摘要： The present invention relates to methods and arrangements in a multi-antenna radio communication system, in particular to methods and arrangements for improved multiple HARQ transmission in such systems. While HARQ transmission schemes, as known in the art, only can consider the fact whether or not a transmission attempt has been successful the present invention provides a HARQ retransmission scheme that considers the reception quality for already performed transmissions of a same data packet when selecting a resource allocation for necessary re-transmissions. Resource allocation for retransmissions is based on a pre-defined metric indicating a quality of the reception of the previous transmission attempts. Such a metric can be derived from a quality measure derived in the receiver unit, e.g. a CQI or CSI-based value, or an appropriate measure of the mutual information, e.g. the accumulated conditional mutual information (ACMI).

摘要： In a radio network a determination is made whether to implement cyclical delay diversity (CDD) for a radio frequency connection involving a radio base station (26) and a wireless terminal (30). The determination whether to implement cyclical delay diversity (CDD) is made in accordance with interference distribution at the wireless terminal (30), as such interference distribution is measured or otherwise perceived. When a determination is made to implement the cyclical delay diversity for the connection, plural transmit antennas (38) of the radio base station (26) are employed to implement the cyclical delay diversity for the connection. One or more indications of the interference distribution may be received and used to make the determination. The indication(s) of interference distribution can take the form of information received from the wireless terminal, and/or the form of frequency reuse plan information for interfering cells. For example, the determination to implement the cyclical delay diversity can be made affirmatively if the frequency reuse for interfering cells is above a predetermined frequency reuse number. In differing embodiments, either the radio base station (26) or the wireless terminal (30) can make the CDD implementation determination.

At least one other mobile terminal located within said cell having the same beam pattern associated therewith as that of said identified beam pattern to be served during said slot is scheduled.
