摘要： Providing for a multipoint equalization (MPE) framework for coordinated multipoint (CoMP) transmission in wireless communication is described herein. The disclosed MPE framework involves distributed scheduling decisions for CoMP transmission, reducing complexity of scheduling coordination as compared with centralized scheduling techniques that coordinate scheduling decisions for multiple network base stations. Further, the MPE framework involves distributed computation of CoMP transmission coefficients, relying on a maximum of two backhaul hops to obtain information for the computation, and disseminate the transmission coefficients. The disclosed MPE framework shows substantial gains in various network deployments over conventional CoMP techniques.

摘要： Techniques for reporting channel state information (CSI) based on scalable channel feedback are described. A user equipment (UE) may receive data transmission from one or more cells among a plurality of cells and may report CSI for each of the plurality of cells. For scalable channel feedback, the UE may report CSI with different granularity for different cells. The granularity of feedback for each cell may be selected based on the quality of a communication channel between the cell and the UE, which may be determined based on a long-term channel gain for the cell. The granularity of feedback may be defined by a subband size, a reporting interval, granularity of quantization of CSI, etc. The UE may report CSI for each cell based on the granularity of feedback for the cell. The UE may receive data transmission sent by at least one cell based on the reported CSI.

摘要： Techniques for reporting channel state information (CSI) are described. A user equipment (UE) may receive data transmission from one or more cells among a plurality of cells and may report CSI for each of the plurality of cells. In an aspect, the UE may generate CSI with different quantization granularity (e.g., different codebook sizes), or different frequency granularity (e.g., different subband sizes), and/or different time granularity (e.g., different reporting intervals) for different cells based on the performance impact of each cell for data transmission to the UE. The performance impact of each cell may be determined based on a long-term channel gain or received power of the cell at the UE. The UE may quantize the CSI for each cell based on the codebook size for the cell. The UE may generate the CSI for each cell based on the subband size and/or the reporting interval for the cell.

摘要： Techniques for scheduling UEs are described. In one design, a scheduler (e.g., for a cell) may receive channel direction information (CDI) and channel strength information (CSI) from a plurality of UEs. In one design, the CDI from each UE may include at least one eigenvector, and the CSI from each UE may include at least one singular value corresponding to the at least one eigenvector. The scheduler may schedule at least one UE among the plurality of UEs for data transmission based on the CDI and CSI from the plurality of UEs. The scheduler may select the at least one UE based on a metric related to signal-to-leakage ratio (SLR), or spectral efficiency, etc. In one design, the scheduler may evaluate the performance of different sets of UEs to determine whether to schedule one UE for single-user MIMO or multiple UEs for multi-user MIMO.
