Abstract:
1. A method for signaling multi-user multiple-input multiple-output (MU-MIMO) transmission parameters, the method comprising: receiving a downlink control information message with a distributed virtual resource block (DVRB) flag, a power share bit, and two transmission precoding matrix index (TPMI) bits conveying the transmission parameters on a condition of a two transmitting antenna configuration, wherein the two TPMI bits indicate TPMIs of wireless transmit receive units (WTRUs) co-scheduled using the two transmitting antenna configuration; receiving a downlink control information message with a DVRB flag and six TPMI bits conveying the transmission parameters on a condition of a four transmitting antenna configuration, wherein the six TPMI bits indicate TPMIs of WTRUs co-scheduled using the four transmitting antenna configuration, and wherein power sharing for the four transmitting antenna configuration is obtained from the six TPMI bits; and processing the downlink control information messages and the transmission parameters associated therewith to provide MU-MIMO reception for the two transmitting antenna configuration and the four transmitting antenna configuration.
