  • Publication number: 20100107041
    Abstract: Method and System for Utilization of an Outer Decoder in a Broadcast Services Communication System is described. Information to be transmitted is provided to a systematic portion of a plurality of transmit buffers and encoded by an outer decoder communicatively coupled to the transmit buffer. The resulting redundant bits are provided to a parity portion of each transmit buffer. The content of the transmit buffers, is multiplexed and encoded by an inner decoder to improve protection by adding redundancy. The receiving station recovers the transmitted information by an inverse process. Because a decoding complexity depends on the size of a systematic portion of the transmit buffer, reasoned compromise between a systematic portion size and number of transmit buffers yields decreased decoding complexity.

  • Patent number: 7630719
    Abstract: A method and apparatus for rapidly assigning traffic channels to a plurality of mobile stations in a wide area high-speed packet data cellular communication system. Mobile stations transmit access probes on randomly selected access channels to selected base stations to initiate traffic channel assignments. The access probe comprises a pilot preamble, a traffic channel request, and a pilot/data request channel (DRC). The pilot preamble allows the selected base station to easily detect the access probe transmission. The traffic channel request includes data that identifies the mobile station. Immediately after transmitting the traffic channel request, the mobile station begins communicating with the base station on both the forward and reverse communication links. The selected base station immediately supervises the mobile station's transmission power. The mobile station selects from a group of available power control sub-channels.

  • Patent number: 7499427
    Abstract: In a data communication system capable of variable rate transmission, high rate packet data transmission improves utilization of the forward link and decreases the transmission delay. Data transmission on the forward link is time multiplexed and the base station transmits at the highest data rate supported by the forward link at each time slot to one mobile station. The data rate is determined by the largest C/I measurement of the forward link signals as measured at the mobile station. Upon determination of a data packet received in error, the mobile station transmits a NACK message back to the base station. The NACK message results in retransmission of the data packet received in error. The data packets can be transmitted out of sequence by the use of sequence number to identify each data unit within the data packets.

  • Patent number: 7400606
    Abstract: In a CDMA data communication system capable of variable rate transmission, utilization of beam switching techniques decreases the average interference caused by transmissions of a base station to subscriber stations within a cell, and in neighboring cells. Base stations utilize multiple transmit antennas, each transmitting signals at controlled amplitudes and phases, to form transmit signal corresponding to sector divisions. Data and reference signals are transmitted along sector division beams that alternate according to fixed time slots in order to increase system capacity and data rates by maximizing carrier-to-interference ratios (C/I) measured at subscriber stations.

  • Publication number: 20070286142
    Abstract: Methods and apparatus for communicating between an access terminal (AT) and an Access Point (AP) are described. For communications over the air link, between an AP and an AT a PN (Pseudo-random Noise) code based address is used as an AP identifier, e.g., address. The PN code based address may be based on Pilot PN code based signals received from an AP. Thus, the PN based AP address may be determined from pilot signals received from an AP. The PN based AP address may be a shortened version of a PN code corresponding to an AP, a full PN code corresponding to an AP, or a value which can be derived in a known manner from a PN code corresponding to an AP.

  • Publication number: 20070286152
    Abstract: Addressing methods and apparatus which use airlink resources in an efficient manner are described. In order to use airlink resources efficiently, a variety of address types are supported. The number of bits in the address may vary depending on the type. In order to support a variety of different address types, of different lengths, in one embodiment, an address used for communications over an airlink is constructed by including in the address an address type field used to communicate an address type indicator and, optionally, an address field used to communicate an address value. The address field is variable in length and may be null, requiring the communication of no bits in this field, for certain types of addresses. Four types of addresses which may be supported include: i) an Access Terminal assisted address, ii) a Network assisted address, 3) a Pilot PN based address; and 4) a reserved address.

  • Publication number: 20070286151
    Abstract: Methods and apparatus for communicating between an access terminal (AT) and a device serving the AT by way of an Access Point (AP) are described. In accordance with one feature serving devices may be assigned specific addresses which are interpreted based on the source of the communication, e.g., MAC packet, in which the address is used. Such addresses may be interpreted as being of a different type than other addresses which can be interpreted and/or used without taking into account the identity of the sender. In some embodiments Session Controllers and/or Internet Attachment Points (IAPs) are identified with such addresses. The address value is the same for one or more ATs but is interpreted at an AP receiving such the IAP address based on information corresponding to the AT which sent the packet including the IAP or Session Controller address.

  • Patent number: 7308100
    Abstract: A method and apparatus for time-based charging for viewing content from a broadcast-multicast service (BCMCS) at a mobile station of a wireless communication system is disclosed. A count value (SKCount) is determined based upon the number of generated short-term keys (SK) that are used to decrypt particular content from the BCMCS. The amount of time the particular content is viewed at the mobile station may be determined as a function of the count value (SKCount) and the period (SKPeriod) between the generation of the short-term keys. This provides information about a user's actual content view time since the short-term key is needed to view the particular content broadcast to the mobile station.

  • Patent number: 7272138
    Abstract: A novel method and apparatus is presented for providing transparent mobility of an entity within a network, by allowing the entity, which has a communication path set up between it and a peer entity, to move from one location to another, without informing the peer entity of this movement, and without having the communication path broken. The invention is applicable to decentralized networks using IP protocols, and is particularly applicable on networks where the mobility mechanism neither introduces latency nor decreases the available bandwidth of the network. In the invention, neither is latency increased nor is bandwidth utilization increased, as is done in other mobility models. Additionally, the invention utilizes standard protocols that are widely available from a plurality of equipment manufacturers on a variety of platforms. Thus, the invention provides a very cost-effective model for network providers that need to support transparent mobility within their networks.

  • Patent number: 7233794
    Abstract: A communication system that allows a soft handoff to be completed, even when the communications link between the active base station and the mobile station deteriorates before the mobile station has received the handoff direction message. The mobile station maintains a list of base stations that the mobile station is in communication with, referred to as an “Active Set”. In addition, the mobile station maintains another list of base stations that are proximate to the base stations in the active set. This list is referred to as the “Neighbor Set”. A memory within the mobile station includes information that would allow the mobile station to demodulate information transmitted from those base stations on the neighbor set. In accordance with the disclosed method and apparatus, the mobile station places a base station in the active set upon including the base station in a pilot strength measurement message (PSMM).
