Abstract: The present invention is directed to systems and methods for measuring the interference for computation of signal to interference ratio (SIR) in DSSS CDMA cellular communication systems, by selectively using a transmission gap in one of the control channels. A specific example embodiment is directed to the computation of the SIR in a system, such as the 3GPP system, where PCCPCH data is multiplexed with SCH data in the downlink from the base station. At the mobile unit, once the PCCPCH is located in the received communication signal, the receiver measures the traffic interference in a chip period in the PCCPCH channel that corresponds to an interval where there is a transmission gap in the PCCPCH data. This gap is provided in the 3GPP system for permit the transmission of primary and secondary SCH data. The SIR is readily determined using the measured interference in the transmission gap.

Abstract: Matching a rate of data bits, in a matrix of data bits interleaved by a predetermined interleaving process, to a desired rate by deletion of redundant data bits or repetition of data bits derived from the matrix. It includes steps of determining in a non-interleaved matrix of the data bits a pattern of bits to be deleted or repeated to provide the desired data rate, decoding an address of each bit in said pattern in a manner inverse to the interleaving process to product a respective address of the bit in the matrix of interleaved data bits, and deleting or repeating the respective bit in the interleaved data bits in dependence upon the respective address. The address decoding is performed in the same manner as a coding of addresses for producing the interleaved data bits from the non-interleaved matrix of the data bits.

Abstract: A system and method is presented for reuseing its S-CDMA related hardware (e.g., timestamp, minislot and frame count hardware) to create an extended mode to DOCSIS 2.0, namely to allow the TDMA channel to have any minislot size as is afforded to the S-CDMA channel. This reuse of existing S-CDMA hardware to create the extended mode is accomplished without the burden (e.g., complexity, cost, and schedule) of additional hardware to perform a separate set of calculations. In order to accomplish the foregoing, parameters are determined to use in a S-CDMA-type UCD message such that when that UCD message is interpreted by both the cable modem and CMTS hardware as though it were an S-CDMA message, the result is an TDMA minislot size that represents a desired integer number of ticks per minislot. In addition, the system and method periodically constructs the relationship between the system timestamp count, a channel's minislot count and the frame count via a timestamp snapshot.

Abstract: A method and apparatus related to a communication system in which a plurality of remote units encode data bursts using a predetermined codeword set and transmit the encoded data bursts to a hub station over a multiple-access channel. When the hub station receives a data burst from one of the remote units, the hub station demodulates the received data burst and correlates the received data burst with each codeword within the predetermined codeword set to determine which codeword has the maximum correlation. The hub station uses the correlation to derive a timing synchronization signal and/or a carrier frequency adjustment signal to be sent back to the remote unit. The signals provide information to the remote unit to synchronize its timing or adjust its carrier frequency for transmitting subsequent data bursts. The hub station may also use the correlation to estimate a signal-to-noise ratio.

Abstract: In a code division multiple access communication system, a method and apparatus provide for an efficient testing of operating behavior of a quality indicator bit. The method and the accompanying apparatus include configuring a receiver to expect to receive a communication channel at a full data rate, and transmitting a signal from a transmitter to the receiver. The signal is carrying the communication channel at a data rate other than said full data rate, and at a power level for receiving at the full data rate. Consequently, the receiver fails to receive the communication channel at the full data rate. A received signal to noise ratio of the received signal at the receiver is determined. A value of the quality indicator bit is determined based on the determined signal to noise ratio. The determined value of the quality indicator bit is communicated to the transmitter.

Abstract: A method and apparatus for controlling uplink transmission powers of mobile stations in the cellular system are disclosed. Because mobile stations have inherent limitations and output power dynamic range, one mobile station which migrates very close to a common base station may be instructed to reduce its transmission power level to an amount which is less than the inherent mobile station minimum output power threshold. If the mobile station does not reduce power, it dominates neighboring mobile stations, causing other mobile stations which are operating within acceptable parameters to be dropped in favor of the dominating mobile station. The present invention provides a method and apparatus for removing an offending mobile station transmission until a path loss increases to the point that the offending mobile station can operate within acceptable reception power levels by transmitting at its inherent minimum power level.

Abstract: A downhole telemetry system employing code division multiple access (CDMA) is disclosed. In one embodiment, the downhole telemetry system comprises one or more downhole transmitters and an uphole receiver. Each of the downhole transmitters transmits a corresponding uplink signal which is generated using amplitude modulation of corresponding code word signals. The code word signals are orthogonal to each other, and the transmitters may be configured to adjust the timing to assure synchronous arrival of the various uplink signals at the receiver. Each of the transmitters may be allocated a different number of code words when it is desired to allow for unequal bandwidth requirements. Such allocation is preferably dynamic. Additional modulation techniques may be employed with CDMA, including frequency division multiplexing, time division multiplexing, and frequency re-use.

Abstract: A communications waveform format is provided for a satellite-based telecommunications system. The waveform format includes forward and return link waveforms between the satellite, earth stations and terminals.

The forward and return link spectrum may be divided into channels, the frequencies and spacing of which are adjustable to compensate for Doppler effects, thereby maintaining synchronization. The spectrum of the terminal links may be divided into multiple subbands (e.g., 38), each of which may support multiple (e.g., 80) ODS-CDM channels.

Abstract: A hybrid DSMA-CR/CDMA methodology provides efficient access to one of a group of common packet channels in a cell of a spread spectrum wireless communication network. The base station broadcasts status information as to the availability and/or available data rates for each common packet channel (CPCH) or group of CPCH channels. Each mobile station uses the status information to select an available channel and/or a channel with sufficient data rate. The mobile station then starts transmission of a series of access preambles, each of which contains a signature corresponding to the selected channel. The mobile station transmits the preambles at increasing power levels. When the base station detects a preamble transmission, the base station responds with a corresponding acknowledgment. Upon receiving this acknowledgment, the mobile station preferably selects a collision detection (CD) signature and transmits a CD preamble containing that signature.

Abstract: A wireless communications system employs code-division multiple access information transmission techniques where the uplink and downlink transmission bandwidths are unequal. The higher bandwidth is an integer multiple of the lower bandwidth. The present system requires a base station and a subscriber unit to have two pseudo-random code generators which can be clocked separately. Alignment of the uplink and downlink pseudo-random spreading codes is achieved by truncating the code sequence for the lower speed link at the conclusion of a complete code sequence for the higher speed link.

Abstract: The present invention uses a portion of an orthogonal spreading code space in a CDMA spectrum for uplink signaling from a user element to a base station. By assigning the user elements one or more signaling codes, which are orthogonal to those used to spread data, to use for uplink signaling, the present invention significantly reduces interference between signaling channels, and between the data channels and the signaling channels, while supporting additional capacity. The signaling codes may be individually assigned to user elements or assigned to groups of user elements. Further, different length signaling codes may be assigned to the user elements to support different signaling rates depending on Quality of Service (QoS) requirements.

Abstract: A slot-aligned IQ data buffer scheme has a third buffer that allows a processing engine to slide the selection of a vector to be processed so that it aligns with the framing of the data. This is particularly advantageous for CDMA and WCDMA systems where there are overlaying coded data streams, each with its own frame timing, since data is processed cleanly at boundaries in the data such that the processing hardware can be minimized. A first level of muxing selects a pair of buffers having the data to be processed from among three buffers. A second level of muxing selects the sample number required. The third level of muxing selects the correct chips for the alignment of the slot. The third stage is implemented with a barrel shifter to minimize hardware generally associated with use of multiplexing.

Abstract: A mobile station provides for a more robust reacquisition process with the base station. The mobile station performs an evaluation of the signal conditions from the base station. The mobile station may perform this evaluation at the end of a call, upon release, or immediately after release. If the signal is strong, the mobile station will jump directly back to the synchronization channel. However, if the signal has deteriorated, the mobile station may determine it is more appropriate to reacquire the pilot signal of a base station. The mobile station may also use the signal characteristics to determine whether to perform a full acquisition, a quick acquisition, or a wide acquisition. The mobile station may also use a history to assist in the reacquisition process.

Abstract: A service option overlay for a CDMA wireless communication in which multiple allocatable subchannels are defined on a reverse link by assigning different code phases of a give long pseudonoise (PN) code to each subchannel. The instantaneous bandwidth needs of each on-line subscriber unit are then met by dynamically allocating none, one, or multiple subchannels on an as needed basis for each network layer connection. The system efficiently provides a relatively large number of virtual physically connections between the subscriber unites and the base stations on the reverse link for extended idle periods such as when computers connected to the subscriber unites are powered on, but not presently actively sending or receiving data. These maintenance subchannels permit the base station and the subscriber units to remain in phase and time synchronization. This in turn allows fast acquisition of additional subchannels as needed by allocating new code phase subchannels.

Abstract: A smart different prime code multiplexing system. Using the characteristic that two different prime codes do not interfere with each other, these two prime codes are combined to replace the conventional asynchronous division multiple access. Without affecting the user and the original data, in the original optical fiber transmission system, other users or data are dynamically added to improve the insufficient capacity of the prime code system. The decoding capacity is thus raised to achieve the objective of multiple access. Furthermore, in the invention, a synchronous parallel prime code is used to increase the original asynchronous decoding capacity. Therefore, a decoding capacity in the asynchronous system similar to that of the synchronous system is obtained. Characteristics such as ultra-high capacity and ultra-high operating speed can also be achieved.

Abstract: A greater variety of frequency combinations may be utilized in multiple situations, including, by way of example but not limitation, hard handovers, soft handovers, macrodiversity, etc. Soft handovers, for example, may be executed between two base stations (BSs) with respect to a mobile station (MS) in which the uplink (UL) and downlink (DL) frequency pairs used to communicate with each base station differ from each other. For instances, only the UL carrier channel, only the DL carrier channel, or both the UL and the DL carrier channels may differ for the respective communications between the MS and the respective BSs. In the first two cases in which only one carrier channel differs, variable duplex distance (VDD) is implemented. In the third case in which both carrier channels differ, constant duplex distance (CDD) is implemented.

Abstract: A received power of a code division multiple access (CDMA) signal is determined. Samples of a spectrum associated with the received CDMA signal are taken as received samples, which are then correlated with a code of the CDMA signal. For correlated samples below a first threshold, those correlated samples are processed by being made to be zero. For samples between the first threshold and a second threshold, those correlated samples are processed by rescaling. The correlated samples above the second threshold are passed unchanged. The received power level of the received CDMA signal is determined using the correlated samples after the processing.

Abstract: Disclosed is a method of setting an initial transport format combination (TFC) in a MAC layer of a CDMA system. the MAC layer selects the initial maximum useable TFC value using transport format set (TFS) and transport format combination set (TFCS) information received from a radio resource control (RRC) layer during an initialization of a channel setting among respective layers, and sets the initial maximum useable TFC by transmitting the initial maximum useable packet data unit (PDU) value to the respective radio link control (RLC) layers according to the selected initial maximum useable TFC value. The RLC layer sets the proper maximum PDU by comparing the initial maximum useable PDU value predetermined during the above process with buffer occupancy (BO), and if the initial data is generated, it transmits the data of a proper size to the MAC layer at the transmission time interval (TTI) when the initial data is generated.

Abstract: When employing HARQ in soft handover (SHO) in a mobile communication system, a mobile station in communication with multiple base stations is signaled by each of the base stations when a packet sent by the mobile station is correctly received. However, while one or more base stations may have received the transmission correctly, others may not have, and retransmission may be called for. To address the possibility of having to resend such a packet, the mobile station of the invention retransmits only if a selected number of the base stations received the transmission incorrectly and does not if at least one base station received the original transmission correctly. The mobile transmits at a rate selected according to a rule from data rate information or signaling received from one or more of the base stations. The network is then able to retrieve the packet from one or more of the base stations which have received it correctly and to supply it to another or others which have not.

The display areas are arranged in the Paley order, and therefore the display areas do not overlap with one another.
