SYMMETRIC AND FULL DUPLEX RELAY IN WIRELESS SYSTEMS |
摘要 |
This invention presents methods comprising a BS with a plural of antennas capable of beamforming two or more spatial multiplexed streams with two or more antennas on UEs; using one or more of relays to project the capacity of the BS to cover one or more UEs; the BS estimating the uplink channel state information (CSI) between each antenna on the BS and each antenna on the one or more UEs using pilots transmitted from the UE antennas in the presence of the relays which amplifies and forwards the one or more pilots; and, the BS making use of the perseverance of the reciprocity of the over the air channel by the symmetry of the DL and UL paths of the relays to obtain the downlink CSI using the estimated uplink CSI that includes the effect of the relays. |
