摘要： Embodiments of the invention provide methods for maximizing the bandwidth utilization in the uplink of a communication system supporting time division multiplexing between unicast and multicast/broadcast communication modes during transmission time intervals in the downlink of a communication system. This is accomplished by multiplexing at least unicast control signaling for UL scheduling assignments in TTIs supporting the multicast/broadcast communication mode. Moreover, multiplexing of unicast control signaling can also be accomplished by splitting a symbol of the multicast/broadcast TTI into two shorter symbols with the first of these two shorter symbols carrying at least unicast control signaling and the second of these shorter symbols carrying multicast/broadcast signaling.

摘要： A method of power saving for a wireless transceiver (FIGS. 1 and 2) is disclosed. The transceiver has an active power mode (504) and a reduced power mode (510). The transceiver is operated in the reduced power mode (510) and monitors transmissions from a remote wireless transmitter while in the reduced power mode. The transceiver identifies a transmission from the remote wireless transmitter by a transceiver identity included in the transmission (FIG. 6, UE identification). The transceiver transitions to the active power mode (512) in response to identifying the transmission.

摘要： The present invention provides an apparatus, system and method for removal of interference due to multi-path for multiple transmit antennas (hereinafter referred to as MTA-MPIC) for High Speed Downlink Packet Access (HSDPA) encoded for transmit diversity, such as Space-Time Transmit Diversity (STTD). For a single receive antenna, the signal is received (25) and each multi-path delayed signal is demodulated (21). The demodulation can include long code removal and despreading. Subsequently, each demodulated signal is received by the RAKE receiver (22) for determining the channel estimate and channel normalization for the total HSDPA signal, and for computing space-time decoding for the HSDPA signal. Following the space-time decoding, a data decision is made (23). Next, reconstructed interference signals are generated (24) and combined with the received signal (25). For other user signals, an interference estimate is made from the despreader (322) outputs without applying the RAKE/space-time coding operations.
