摘要： In this disclosure, methods for antenna combining to meet the pilot requirement of the massive MIMO system, and apparatuses for the same are provided. In a user equipment (UE) perspective of view, the UE transmits first pilot signals via each of multiple antennas of the UE, and receives antenna combining information from a base station. Here, the antenna combining information combines the multiple antennas into one or more antenna groups based on the first pilot signals, and each of orthogonal sequences is allocated to each of the antenna groups. The UE transmits second pilot signals using the allocated orthogonal sequences for each of the antenna groups. The second pilot signals can be used for estimating downlink channel from the base station to the UE.

摘要： Grouping based reference signal transmission scheme for massive MIMO is disclosed. UEs are grouped and each UE group receives information on a sequence used for the uplink reference signal from a base station. The information is determined to assign orthogonal sequences to UEs within a UE group considering at least one or more of a number of orthogonal sequences, a number of the UEs within the UE group, amount of information to be transmitted, channel condition between the base station and each UE, and a number of sequences assigned to each UE of the UEs.

摘要： A reference signal transmission scheme is presented. A first user equipment (UE) receives first information identifying which uplink subframe of a plurality of subframes is enabled to transmit an uplink reference signal, and receives second information identifying a sequence used for the uplink reference signal from a base station. The first information is used to identify a different uplink subframe to a first UE group including the first UE and a second UE group other than the first UE group. The second information is determined to assign different orthogonal sequences to each of UEs of the first UE group. The first UE transmits the uplink reference signal to the base station at the uplink subframe identified by the first information using the sequence identified by the second information.
