A transmitting device comprises a plurality of distributed transceivers, a baseband processor and a network management engine. Data streams are generated at baseband by the baseband processor. Diversity coding such as space-time coding may be performed over the generated data streams in the baseband. The transmitting device concurrently transmits each of the coded streams in a same radio frequency (RF) band to a receiving device over the entire distributed transceivers through associated antennas. When needed, the network management engine may identify one or more auxiliary devices providing available transceivers and antenna beamformers to the transmitting device for sharing. Beam patterns and antenna orientations may be determined for associated antennas of the available transceivers for the transmitting device.

A method and system for controlling discontinuous reception (DRX) in a mobile device in a wireless communications network uses autonomous DRX control after initial VoIP traffic setup. If the mobile device transmits a negative-acknowledgement signal (NACK) indicating unsuccessful receipt of a VoIP packet, then it autonomously turns on a predetermined delay time later to receive the retransmission of the VoIP packet. The predetermined delay time is related to the time for the base station to process the NACK and prepare the VoIP packet for retransmission. When the mobile device transmits or retransmits a VoIP packet, reception is deactivated, but is autonomously activated the predetermined delay time later to receive an acknowledgement signal (ACK) or NACK.
