摘要： According to one or more aspects, the teachings herein improve user equipment (UE) Channel State Information (CSI) feedback, by letting the precoder part of a CSI feedback report comprise factorized precoder feedback. In one or more such embodiments, the factorized precoder feedback corresponds to at least two precoder matrices, including a recommended "conversion" precoder matrix and a recommended "tuning" precoder matrix. The recommended conversion precoder matrix restricts the number of channel dimensions considered by the recommended tuning precoder matrix and, in turn, the recommended tuning precoder matrix matches the recommended precoder matrix to an effective channel that is defined in part by said recommended conversion precoder matrix.

摘要： A system, method and node of single-carrier layer shifting for multiple- stream transmission in a network. Per-symbol layer shifting for multiple-stream transmission is implemented using DFTS-OFDM as an access technique. Code word-to-layer mapping is fixed within a DFTS-OFDM symbol and only shifted across consecutive DFTS-OFDM symbols. The method begins by receiving a multiple-stream transmission by a mapping module for transmission. The transmission includes a plurality of subframes and information carrying symbols transmitted on a plurality of layers. A per-symbol layer shifting scheme is then implemented on the transmission where layer shifting is conducted upon each symbol.

摘要： The present invention relates to a method and arrangements in a communication system for Multi User Multiple-Input-Multiple-Output (MU-MIMO) signaling via Multiple-Input-Multiple-Output (MIMO) antennas between a base station and one of a plurality of mobile terminals supporting both Single User and Multi User Multiple- Input-Multiple-Output (SU-MIMO and MU-MIMO) signaling modes. Switching between the modes is supported in the system and the modes have partly shared signaling.

Bits, i.e. data bits, of the identified redundant signaling is re-interpreted or re-defined to comprise signaling information associated with MU-MIMO mode. The signaling information associated with MU-MIMO mode is signaled to the mobile terminal by using the reinterpreted redundant bits.
