    摘要: The present application relates to a method for operating a cellular multiple input and multiple output system comprising a first device (20) having at least two antenna arrays (22, 23) and second device having at least two antennas (32, 33). According to the method, a same uplink pilot signal is broadcasted from each antenna (32, 33) of the second device (30) and the same uplink pilot signal is received at each antenna array (22, 23) of the first device (20). At the first device (20), first device transmission parameters are determined for each antenna array (22, 23) depending on the received same uplink pilot signal. Downlink pilot signals are sent via antenna array (22, 23) using the determined first device transmission parameters and the downlink pilot signals are received at each antenna (32, 33) of the second device (30). This second device determines second device receiving parameters for each antenna (32, 33) depending on the received downlink pilot signals.

    摘要: Enhanced sounding reference signal (SRS) transmissions for multiple input, multiple output (MIMO) operation are disclosed in which a user equipment (UE) detects an observed interference level for each receiver chain of the UE. In response to an imbalance, the UE precodes a SRS targeting downlink operation to indicate the imbalance. The UE then transmits the precoded SRS. In alternative aspects, the precoded SRS vector may be determined by an evolved nodeB (eNB). In such aspects, the eNB determines the precoded SRS vector targeting downlink operations for the served UEs, wherein the determined precoded SRS vector includes determining the precoded SRS vector on a per UE basis, enabling the precoded SRS vector for either one or both of frequency division duplex (FDD) systems and time division duplex (TDD) systems, or enabling the precoded SRS vector for aperiodic SRS only. The eNB then transmits the determined precoded SRS vector to the UE.

    摘要: A method sends uplink control information from the user equipment to a serving node of a radio communications system by first encoding (1413) uplink control information bits into symbols. The encoded symbols are split (1415) into at least two groups of symbols for use to achieve diversity transmission. Each of the at least two groups of symbols are cyclically repeated (1417) to generate a repeated group for each of the at least two groups of symbols. Then the repeated groups are mapped (1421) each to different transmission ports of the user equipment for diversity transmission as uplink control information through a plurality of uplink transmission slots of the uplink subframe.
