摘要： Method and apparatus for a channel sensitive scheduler for scheduling transmissions in a communication system. The scheduler is defined by a priority function of the channel condition as determined by amount of transmission power needed by a mobile station. In one embodiment the channel condition is determined based on the transmission pilot power of each mobile station and is used to calculate a priority value for each mobile station. The mobile stations are then scheduled to transmit based on the priority value.

摘要： Techniques to mitigate inter-cell interference using joint time and frequency division are described. A frequency band is divided into multiple non-overlapping frequency subbands. The transmission timeline is divided into Tin and Tout time intervals. Data is exchanged with users in at least one inner region of a cell on the entire frequency band in the Tin time intervals. Data is exchanged with users in multiple outer regions of the cell on the multiple frequency subbands in the Tout time intervals. The frequency band may be partitioned into three frequency subbands. Data may then be exchanged with users in first, second and third outer regions on first, second and third frequency subbands, respectively. The regions in which the users are located may be determined based on pilot and/or other measurements.

摘要： Techniques for efficiently sending channel state information using differential encoding are described. Differential encoding may be performed across space, across frequency; across space and frequency, across space, frequency and time, or across some other combination of dimensions. In one design, spatial state information may be determined for multiple spatial channels on multiple subbands. The spatial channels may correspond to different antennas, different precoding vectors, etc. Channel quality indicator (CQI) values may be obtained for the multiple spatial channels on the multiple subbands. The CQI values may be differentially encoded across the multiple spatial channels and the multiple subbands to obtain differential CQI information. In another design, CQI values may be obtained for multiple spatial channels on the multiple subbands in multiple time intervals and may be differentially encoded across space, frequency and time. The differential CQI information and the spatial state information may be sent as feedback.
