    Abstract: A base station (103) operates a hybrid retransmission scheme for a communication to a first subscriber unit (101) over a communication channel of an air interface of a cellular communication system. The base station (103) comprises a retransmission parameter controller (209) which sets a transmission parameter, such as a transmit power or an error correcting scheme, for a transmission of the communication in response to an operating point for the retransmission scheme. A CQI processor (203) determines a channel quality indication for the communication channel and a variation processor (205) determines a variation measure of a variation of the channel quality indication. The variation measure can for example be a rate of change. An operating point controller (207) sets the operating point in response to the variation measure. The invention may allow improved setting of transmission parameters for initial transmissions thereby providing higher throughput, reduced resource

    Abstract: A beamforming processor (133) determines responses for transmit elements (109-115) and receive elements (125-131) for each antenna elements (101-107) of an antenna array. A channel response processor (205) estimates a channel response for each propagation channel between one of the plurality of antenna elements (101-107) and a remote station in response to a signal received from the remote station. A receive compensation processor (207) compensates the channel responses for the receive elements (125-131) but not the transmit elements (109-115). An Eigen beamforming processor (209) then executes an Eigen beamforming algorithm based on the compensated channel responses. The resulting beamform weights are then compensated for the response of the transmit elements (109-115) in a transmit compensation processor (211). By using a separated two stage compensation for responses of the receive elements (125-131) and the transmit elements (109-115), improved beamforming based on Eigen beamforming can be achieved.
