摘要： A communication unit for a radio communication system comprises a receiver for receiving data over an air interface. The receiver can operate in a first diversity mode and a second diversity mode. The first diversity mode may specifically correspond to no receive diversity being employed and the second diversity mode may correspond to signals from two or more fully or partially de-correlated antennas being combined. The communication unit comprises a data unit which determines a first data characteristic for a section of data to be received over the air interface. A switching unit is arranged to switch between the first diversity mode and the second diversity mode in response to the first data characteristic. The invention may allow improved performance and e.g. reduced power consumption by allowing an improved adaptation of diversity operation. In particular, an improved trade-off between power consumption and performance may be achieved in many embodiments.

摘要： A packet data transmission protocol that uses transmission windows includes a packet control unit (PCU) (4, 8) that transmits (100) blocks of data packets from a first transmission window. A user equipment (UE) (2) sends (102) a negative acknowledgement to the PCU if the packets are not received properly, whereupon the PCU construct (106) a dummy radio link control (RLC) block (60), including at least header information upon event of an established (104) trigger (60) event. The PCU sends (108) the dummy RLC block at a more robust coding rate to prevent a RLC stall condition.
