Abstract: Embodiments of the disclosure relate to operational association between communication devices in the presence of a link-budget imbalance between an upstream link and a downstream link at one of the communication devices. The association relies on a request for a narrowband resource block sent form the communication device having the link-budget imbalance to a remote communication device that can schedule and/or allocate the narrowband resource block. The request can be modulated according to an on-off keying modulation scheme or can be encoded according to a multi-repetition encoding scheme. In response to the narrowband resource block being allocated, an association request can be sent to the remote communication device in the narrowband resource block.

Abstract: An approach is provided for defining a 1 MHz preamble of a packet. The approach involves determining a preamble sequence of a packet, the preamble sequence having a determinable length. The approach also involves causing, at least in part, the preamble sequence to be divided into a predetermined number of blocks. The approach further involves causing, at least in part, a mathematical operation and a summation over the predetermined number of blocks and a corresponding number of received blocks. The approach also involves causing, at least in part, the summation to be maximized to determine the preamble sequence corresponds to one of a first bandwidth or a second bandwidth, the second bandwidth being greater than the first bandwidth, to determine a type of the packet.

Abstract: A system and method are provided to intelligently undertake mandated scanning for radar signals prior to operating a particular wireless device in the 5 GHz band. The disclosed systems and methods provide a capability by which wireless devices are enabled to intelligently scan using a 160 MHz signal, or the largest bandwidth that the wireless device has the capacity to occupy. The disclosed scheme makes use of information about the location of the wireless device to determine characteristic of the environment in which the wireless device is operating. Locations of potentially conflicting radar installations, such as at airports and on military installations, are generally “known.” This information is used to compare to a determined geographic location of the wireless device to assess whether full broad bandwidth DFS scanning cane be reasonably undertaken or whether some narrower channel scanning is appropriate for the wireless device based on proximity to radar installations.

Abstract: Generally, embodiments to enable, indicate and detect Short Interframe Space (SIFS) of different time durations, a short (or small) SIFS which is shorter in duration than a regular SIFS, are described herein. Embodiments may comprise logic such as hardware and/or code to signal a short SIFS or a regular SIFS by setting or clearing a bit of a management frame transmitted by a station to an access point during the network association process, or by setting or clearing a bit in the SIG field of the preamble of a data unit transmitted by an access point to an associated station. In some embodiments, a third party station is able to receive the data unit sent by the access point, and decode, e.g., the SIG field bit to determine whether the short SIFS duration or regular SIFS duration is defined for the communication between the access point and the station.

Abstract: A platform to facilitate updating an equalizer in addition to other receiver functionality is disclosed. A transmitting entity transmits one or more pilot tones in each protocol data unit (PDU) such as a packet. A receiving entity is able to derive a sufficiently accurate channel response estimate with the pilot tones under most channel conditions. The method and apparatus rotates the pilot tones through each of the subcarriers over the packet. The pilot tones would be separated by some number of data subcarriers so that estimation of slope and intercept for subcarrier tracking could be maintained. As the pilot tones are swept across the subcarriers, the taps for the equalizer for the subcarriers for which the pilot tones currently populate would be updated as well. This approach allows the system to track channel changes over time.

Abstract: A time division multiple access (TDMA) waveform for controlling a MIL-STD-188-183 compliant demand assignment multiple access (DAMA) satellite communication network contains a short duration and minimal data content, time-hack, that is repeatedly transmitted by a supervisory control radio, so that the time hack occurs twice within a DAMA frame, ensuring that every radio can acquire frame synchronization, irrespective of overlap in receipt of one of the time-hacks with a voice/data channel transmission by that radio. The time-hack also identifies which one among a list of different frame formats stored in the radio is to be employed.

Abstract: Apparatus, and an associated method, for a packet radio communication system that utilizes a packet retransmission scheme. A data packet, together with a selected number of retransmissions thereof are sent to a mobile station, or other receiving station. A channel condition estimator estimates channel conditions on the communication channel and, responsive to the channel condition estimates, selection is made of the number of packet data retransmissions that are to be effectuated prior to performing decoding operations to recover the informational content of the data packet.

Abstract: A receiver and method are provided for receiving signals transmitted thereto from a transmitter during operation of a radio communication system. To synchronize the receiver with the transmitter, the receiver includes a delay lock loop circuit capable of receiving a pilot signal and a diversity signal transmitted from a plurality of transmit antennas and/or received by a plurality of receive antennas. The delay lock loop circuit is capable of calculating a first error signal based upon the pilot signal, and a second error signal based upon the diversity signal. The delay lock loop circuit is then capable of forming a combined error signal based upon the first and second error signals, and capable of synchronizing the receiver with the transmitter based upon the combined error signal.

Abstract: A method detects an absence of a transmitted frame in a wireless communications system that operates with a discontinuous transmission (DTX) protocol between a transmitter and a receiver. The method includes decoding a received signal over a frame period to determine a cumulative metric; normalizing the cumulative metric and comparing the normalized cumulative metric to a threshold for determining whether the frame was a transmitted frame or a non-transmitted frame. The determined cumulative metric may be a maximum cumulative metric or a zero state cumulative metric. The wireless communications system may be a CDMA system, the receiver may be contained within a mobile station, and the determination of whether the frame was a transmitted frame or a non-transmitted frame can be employed, as one non-limiting example, during execution of a power control algorithm.

Abstract: Approximator apparatus, and an associated method, for approximating a Euclidean norm. A transformer transforms component portions of a data symbol into transformed values. And, the transformed values are provided to an estimator. The estimator estimates the Euclidean norm responsive to the transformed values provided thereto. When a higher level Euclidean norm is to be approximated, transforming and estimations are iteratively performed to form successive two dimensional Euclidean norm approximations.
