摘要： A communication device operating in time division duplex (TDD) mode using multiple antennas is provided herein. The communication device uses receive channel estimation measurements to perform transmit beamforming and multiple input multiple output (MIMO) transmission, based on self-calibration of the various up/down paths via a method of transmission and reception between its own antennas, thus achieving reciprocity mapping between up and down links. Either user equipment (UE) or a base station may routinely perform this self-calibration to obtain the most current correction factor for the channel reciprocity to reflect the most current operating conditions present during TDD MIMO operation.

摘要： A mobile device in a (e.g., full rank N×N) MIMO system is augmented by a plurality of kn antennae coupled to at least one of N beamformers such that the total number of antennae M=Σn=1n=N is greater than the total number of beamformers N. A highest gain anchor (e.g., optimal) antenna set may be selected from among a plurality of antenna sets, each antenna set comprising a different one of the kn antennae for each nth beamformer. The phase(s) of the non-selected kn−1 antennae may be set to align with the phase of the selected anchor antenna for each nth beamformer. Using TDD communication, the highest gain anchor antenna set for transmitting during the uplink periods may be determined using information measured by at least some of the plurality of M antennae while receiving during one or more downlink periods.
