Abstract
A method for optimizing re-transmission in a multi-antenna multi-terminal network, the method comprising the following steps performed by a station of the network: receiving from at least one terminal of multiple terminals one or more messages indicating a failed transmission of data sent to the multiple terminals; determining from the received one or more messages if a switching-to-beam-forming criterion is matched and, if the criterion is matched, initiating a re-transmission of the data to the at least one terminal via a beam-forming technique involving one or more of the multiple antennas and using at least one beam for the re-transmission of the data.
Claims22
A method for optimizing re-transmission in a multi-antenna radio base station within a mobile network including a plurality of mobile terminals, comprising the steps of:
- receiving from at least one terminal of multiple terminals one or more messages indicating a failed transmission of data sent to the multiple terminals,
- determining from the received one or more messages if a switching-to-beam-forming criterion is matched, wherein a spatial distribution of the at least one terminal is determined for an adaptation of the switching-to-beam-forming criterion, and
- if the criterion is matched, initiating a re-transmission of the data to the at least one terminal via a beam-forming technique involving one or more of the multiple antennas and using at least one beam for the re-transmission of the data.

12-21. (canceled)
A system for optimizing re-transmission in a multi-antenna radio base station within a mobile network including a plurality of mobile terminals, comprising:
- receiving unit for receiving from at least one terminal of multiple terminals one or more messages indicating a failed transmission of data sent to the multiple terminals,
- processing unit for determining from the received one or more messages if a switching-to-beam-forming criterion is matched, wherein a spatial distribution of the at least one terminal is determined for an adaptation of the switching-to-beam-forming criterion, and
- if the criterion is matched, transmission unit for initiating a re-transmission of the data to the at least one terminal via a beam-forming technique involving one or more of the multiple antennas and using at least one beam for the re-transmission of the data.
