ABSTRACT:
A point to multipoint device for use in a wireless network operates a sequence of variable duration communication channels, allocatable to telecommunications units. A training sequence indication and a repetition rate indication are stored indicating a training sequence and repetition rate for the training sequence in the sequence of communication channels associated with the point to multipoint device. An interface receives a synchronization signal issued to all point to multipoint devices in the wireless network, and uses it to determine a time for a first occurrence of the training sequence to occur. Communication channel control logic causes control data to be transmitted to the telecommunications units identifying the sequence of channels, the training sequence indication and the repetition rate. Beamforming logic determines beamforming weights used to produce a reception beam at an antenna array.
