    Abstract: PROBLEM TO BE SOLVED: To provide techniques for sending control information in a wireless communication system.SOLUTION: A UE spreads control information across frequency with a DFT and across time with an orthogonal sequence. The UE receives codewords for N HARQ processes in N subframes, determines an ACK value for each HARQ process, codes N ACK values for the N HARQ processes to obtain ACK information, determines output data for the ACK information, and sends the output data in one of M uplink subframes. First control information is processed based on a first coding and multiplexing scheme utilizing code division multiplexing in the time and frequency domains. Second control information is processed based on a second coding and multiplexing scheme utilizing code division multiplexing in the time domain and spreading in the frequency domain.

    Abstract: PROBLEM TO BE SOLVED: To facilitate efficiently indicating parameter(s) associated with a base station utilizing synchronization signals in a wireless communication environment.SOLUTION: Relative locations of a PSC and an SSC in a radio frame can be a function of a parameter. A PSC sequence utilized to generate PSCs can be selected based upon a parameter. Inclusion or exclusion of PSCs from a radio frame can be a function of a parameter. Pseudo random sequence mappings (e.g., to cell IDs or tone locations) can be a function of a parameter. Parameters indicate whether the base station is part of a TDD or FDD system, whether the radio frame employs FS1 or FS2, whether the base station is associated with a macro or femto cell, or whether the base station is associated with a unicast or multicast system.

    Abstract: PROBLEM TO BE SOLVED: To efficiently manage reverse-link resources by allowing a mobile station to select between transmitting a payload at a standard power level and transmitting a smaller payload at a boosted power level.
    SOLUTION: The mobile station can autonomously select a QoS (quality of service) level for physical layer packets. Based on reverse-link transmission information received from a base station, the mobile station derives a reverse-link transmission guideline defining the power levels and associated payloads for at least a standard service and boosted service. The mobile station selects a reverse-link transmission power level from a plurality of power levels, including at least a standard reverse-link transmission power level associated with a standard payload size and a boosted reverse-link transmission power level associated with a boosted payload size, where the standard payload size is greater than the boosted payload size.
