摘要： A method, an apparatus, and a computer program product for wireless communication are provided for separating control transmissions and data transmissions within the coverage area of a plurality of transmission/reception points or points that are geographically displaced, the plurality of points comprising a macro node and a plurality of remote radio heads (RRHs) coupled to the macro node. Separating control transmissions and data transmissions in the macro node/RRH configuration may allow UEs to be associated with one set of transmission points for data transmissions and the same set or a different set of transmission points for common control signaling. Separating control transmissions and data transmissions may also allow for faster reconfiguration of antenna ports used for UE data transmission compared with reconfiguration via a handover process.

摘要： Methods and apparatus for enforcing codebook properties (e.g., constant modulus and/or finite alphabet) in adaptive and dual-stage codebooks are described. One example method generally includes receiving multiple feedback aspects of a channel for wireless communications determining multiple codewords based on the multiple feedback aspects, determining a final precoding matrix based on the multiple codewords, enforcing at least one codebook property in at least one of the multiple codewords or the final precoding matrix, applying the final precoding matrix to a plurality of spatial streams to form precoded spatial streams, and transmitting the precoded spatial streams. For certain aspects, enforcing the at least one codebook property includes quantizing elements in each of the multiple codewords and/or the final precoding matrix to the nearest value in a finite alphabet or to increase a performance metric.

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.
