  • Patent number: 8462890
    Abstract: A method and apparatus for jointly decoding a first and second message is disclosed. The signaling scenario illustrated by FIG. 1 and using the codeword properties defined herein, the various embodiments may combine multiple messages under the hypothesis that the value of a message portion corresponding any subsequent observed transmission is different. Accordingly a first buffer may store the first observed message frame (509) and a second buffer may sum the LLR's of subsequent observed frames (513). In the embodiments disclosed, two decoding hypotheses are required only; a first where the two buffers are combined directly (513) and a second where the difference codeword bit LLR's of the first buffer (509) are inverted before combining with those of the second buffer (519). A maximum of N transmissions is allowed by the receiver (523), after which a decoding failure is declared.

  • Patent number: 8463313
    Abstract: A communication system supports H-ARQ, AMC, active set handoff, and scheduling functions in a distributed fashion by allowing a mobile station (MS) to signal control information corresponding to an enhanced reverse link transmission to Active Set base transceiver stations (BTSs) and by allowing the BTSs to perform control functions that were supported by an RNC in the prior art. The communication system allows time and SIR-based H-ARQ flush functions at the BTSs during soft handoff (SHO), provides an efficient control channel structure to support scheduling, H-ARQ, AMC functions for an enhanced reverse link, or uplink, channel in order to maximize throughput, and enables an MS in a SHO region to choose a scheduling assignment corresponding to a best TFRI out of multiple assignments it receives from multiple active set BTS. As a result, the enhanced uplink channel can be scheduled during SHO without any explicit communication between the BTSs.

  • Patent number: 8396047
    Abstract: A wireless communication device receives at least a section of a subframe from a base station in a wireless communication system. The subframe includes transmission resources multiplexed onto subcarriers of orthogonal frequency division multiplexed (OFDM) symbols. A first set of OFDM symbols includes a reference signal and at least a second set of OFDM symbols includes information other than the reference signal (e.g., channel-coded data). The wireless device determines which OFDM symbols of the subframe constitute the first set of OFDM symbols based on an identifier associated with a base station that transmitted the subframe. The wireless device may then process the reference signal from the OFDM symbols that are determined to be the first set of OFDM symbols. The wireless device may also determine which OFDM symbols of the subframe constitute the second set of OFDM symbols and process non-reference signal information from OFDM symbols of the second set.

  • Publication number: 20130028200
    Abstract: A method in a wireless communication terminal includes receiving configuration signaling for transmitting on a first set of radio resources wherein transmitting only on the first set of radio resources leads to a time-domain periodic repetitive pattern of transmissions from the terminal in a transmission interval that causes interference to a companion device communicably coupled to the wireless communication terminal. The terminals selects a second set of radio resources for transmitting on in the transmission interval such that transmissions on a combination of the second set of radio resources and the first set of radio resources does not lead to a periodic repetitive pattern of transmissions from the terminal in the transmission interval.

  • Publication number: 20120281594
    Abstract: A broadband cellular network (BCN) provides a user equipment (UE) access to TVWS resources. The BCN authorizes the UE to access TVWS resources by conveying a mobile device identifier received from the UE, and a cell identifier associated with the UE's coverage area, to a Federal Communications Commission (FCC)-certified Database and receiving, from the Database, and storing an FCC ID associated with the UE and a set of available TVWS resources. The BCN then conveys, to the UE via a broadband cellular technology, a channel resource information element (CRIE) that includes the cell identifier and identifies the set of available TVWS resources. Subsequently, the BCN re-authorizes the UE to access TVWS resources based on the stored FCC ID and without re-conveying the mobile device identifier to the Database. The BCN further utilizes broadband cellular technology procedures to provide a “virtual” contact verification signal (VCVS) to the UE.
