摘要： Communication device adapted for receiving a MIMO signal is provided. The device comprises a first detector adapted to perform a first symbol detection on the MIMO signal using a first detection method, a detection error determination unit adapted to determine a first detection error of the first symbol detection, a detection error judging unit adapted to determine if the first detection error is above or below a detection threshold, and a second detector, adapted to perform a second symbol detection on the MIMO signal using a second detection method, if the detection error judging unit has determined that the first detection error is above the detection threshold. The communication device is adapted to use results of the symbol detection as final symbol detection results, if the detection error judging unit has determined that the first detection error is below the detection threshold.

摘要： A method comprising, at a mobile station, transmitting a pilot message to a base station in response to determining that no signal has been received at the mobile station within a predetermined time period or that a received signal has been below a predetermined intensity within a predetermined time period, said pilot message comprising a pilot tone sent at reduced bandwidth, and receiving a response from the base station, said response beamsteered towards the receive direction and/or power of the pilot message.
