摘要： Described are an eNB and a UE implementing a CSI-RS protocol. The eNB has an ordered set of antenna ports for a wireless communication channel with the UE, a first circuitry operable to compose CSI-RS configuration messages that assign to the UE various CSI-RS groups specifying one or more CSI-RS antenna ports, and a second circuitry to establish an ordered list of CSI-RS antenna ports. The UE has a set of antennas, a first circuitry operable to receive from the eNB various CSI-RS configuration messages assigning to it CSI-RS groups specifying one or more CSI-RS antenna ports, and a second circuitry operable to index CSI-RS antenna ports specified by the CSI-RS groups as an ordered list of CSI-RS antenna ports. The eNB may transmit CSI-RS to the configured UE, and the UE may perform channel state information measurements on the ordered list of CSI-RS antenna ports.

摘要： Embodiments of the present disclosure describe devices, methods, computer-readable media and systems configurations for transmission point indication in a coordinated multipoint (CoMP) system. A user equipment (UE) may receive common reference signal (CRS) parameters associated with individual base stations of a CoMP measurement set. The UE may also receive a transmission point index corresponding to a first base station of the CoMP measurement set that is scheduled for communications with the UE. A mapping module of the UE may produce a physical downlink shared channel (PDSCH) mapping pattern based on the CRS parameters associated with the scheduled base station.

摘要： Embodiments for providing fast modulation and coding scheme adaptation for LTE regardless of transmission using single-user multiple-input and multiple-output (SU-MIMO) or multiple-user multiple-input and multiple-output are generally described herein. In some embodiments, channel state information reference signals are sent to user equipment by a node. First channel quality indication feedback based on the channel state information reference signals is received from the user equipment. Physical downlink shared channel data and demodulation reference signals are transmitted using a first modulation and coding scheme based on the first channel quality indication feedback. Second channel quality indication feedback based on measurements performed by the user equipment on the demodulation reference signals is received by a node. Physical downlink shared channel data is transmitted using a second modulation and coding scheme based on the second channel quality indication feedback.

摘要： In a wireless, OFDM system, phase noise may be mitigated through the use of an interleaver that is designed to distribute coded block bits across subcarriers of multiple OFDM symbols. Doing so decreases the non-stationary properties of the noise. Such an interleaver may be a rectangular interleaver that maps each block to a different subcarrier to create frequency diversity and to a different OFDM symbol, to create time diversity. One exemplary method of interleaving the symbols is to place a first symbol at row X and column Y of the interleaver. The next symbol is placed in row X+1 and column Y+1. The result of such an interleaving process is a great reduction in the block error rate.
