Abstract: A mobile station may comprise a receiver to receive, from a base station, a broadcast signal indicating a TDD configuration of uplink OFDM symbols and downlink OFDM symbols. The receiver may receive an indication of a symbol range and a subchannel range for use in transmission of CQI feedback. The mobile station may receive first downlink data and transmit first uplink data, using the TDD configuration, wherein the first uplink data comprises CQI feedback information transmitted in accordance with the symbol range and the subchannel range. The receiver may receive second downlink data, from the base station, on a different frequency as the first uplink data is transmitted, while the first uplink data is transmitted.

Abstract: A method and system for minimizing the control overhead in a multi-carrier wireless communication network that utilizes a time-frequency resource is disclosed. In some embodiments, one or more zones in the time-frequency resource are designated for particular applications, such as a zone dedicated for voice-over-IP (VoIP) applications. By grouping applications of a similar type together within a zone, a reduction in the number of bits necessary for mapping a packet stream to a portion of the time-frequency resource can be achieved. In some embodiments, modular coding schemes associated with the packet streams may be selected that further reduce the amount of necessary control information. In some embodiments, packets may be classified for transmission in accordance with application type, QoS parameters, and other properties. In some embodiments, improved control messages may be constructed to facilitate the control process and minimize associated overhead.

Abstract: A multi-carrier cellular wireless network (400) employs base stations (404) that transmit two different groups of pilot subcarriers: (1) cell-specific pilot subcarriers, which are used by a receiver to extract information unique to each individual cell (402), and (2) common pilots subcarriers, which are designed to possess a set of characteristics common to all the base stations (404) of the system. The design criteria and transmission formats of the cell-specific and common pilot subcarriers are specified to enable a receiver to perform different system functions. The methods and processes can be extended to other systems, such as those with multiple antennas in an individual sector and those where some subcarriers bear common network/system information.
