摘要： A communication system provides for adaptive rank determination, for example, a rank 2 transmission in instances where a rank 1 transmission may be indicated under supported feedback modes in current standards where no explicit power adaptation can be assumed, for example, where a user equipment (UE) is limited to reporting a rank 1 channel due to a large dynamic range of a signal or due to a signal received by the UE from one base station (BS) antenna port drowning out a signal received by the UE from another BS antenna port. The communication system provides for the UE to implement rank 2 transmission in such instances by using per-antenna port power control at a BS serving the UE. In one embodiment, the BS controls the rank determination at the UE by signaling transmit power or power offset related parameters to use for rank and transmission parameters determination and feedback.

摘要： A method and receiver for processing a composite signal (112) in a wireless communication system (100) is provided. The method includes receiving a composite signal (112) within a channel bandwidth, wherein the composite signal comprises one or more symbol streams (108, 110, 116) from a plurality of communication units (103, 104). The method also includes sampling the composite signal at a sampling rate, wherein the sampling rate comprises one of equal to a symbol rate of the composite signal or larger than the symbol rate of the composite signal. In addition, the method includes selecting a symbol sampling phase for each of the symbol streams from a plurality of communication units. The symbol streams from each of the communication units are aligned to produce an aligned composite signal by separating the symbol streams for each of the plurality of communication units and orthogonal recombining the symbol streams for each of the plurality of communication units based on the selected symbol sampling phase for each of the plurality of signals. The symbol streams are also separated based on the aligned composite signal.

摘要： A method and apparatus for performing resource allocation with lower required overhead is provided herein. Resource allocations for data transmissions are chosen in such a way as to provide channel quality information for various parts of the channel bandwidth (frequency selective channel quality information), such as allocating two different resource blocks (on different sets of subcarriers) to a mobile unit for two different transmissions. These data transmissions are used to estimate frequency selective channel quality information, thereby eliminating or greatly reducing the need for channel sounding with a broadband pilot. As a result, the overhead on the uplink of the communication system may be significantly reduced.
