Device scheduling method and system

摘要

A method for scheduling pairs in a plurality of pairs of devices for pair communication in a telecommunication network, each pair of devices including a transmitter and a receiver. The method includes: allocating a different time interval to each of the transmitters for emitting training signals, the training signals allowing determining channel estimates; obtaining channel information from at least one receiver having received training signals emitted by at least one of the transmitters, the channel information being determined by the receiver by analysis of the received training signal, the channel information including a channel estimate of a channel between the receiver and the transmitter that emitted the received training signal; and scheduling for pair communication, in the same time interval, the pairs for which a quality indicator verifies a predefined criterion, the quality indicator being determined using channel estimates obtained from receivers of the pairs in the set.

1. A method for scheduling pairs in a plurality of pairs of devices for pair communication in a telecommunication network, each of said pairs of devices comprising a transmitter and a receiver, said method comprising the following acts implemented by a coordinating device in the telecommunication network:
allocating a different time interval to each of the transmitters of said plurality of pairs for emitting training signals, said training signals allowing determining channel estimates, obtaining channel information from at least one receiver, comprised in a pair of the plurality of pairs, having received training signals emitted by at least one of said transmitters, said channel information being determined by said receiver by analysis of said at least one received training signal, said channel information comprising at least one channel estimate of a channel between said receiver and a transmitter having emitted said at least one received training signal, scheduling for pair communication, in the same time interval, the pairs of a set of pairs in the plurality of pairs for which a quality indicator verifies a predefined criterion, said quality indicator being determined using channel estimates obtained from receivers of the pairs in said set, and determining transmitter beamforming vectors using the channel estimates associated with the scheduled pairs and sending said transmitter beamforming vectors to each associated transmitter of the scheduled pairs, said transmitter beamforming vectors allowing the transmitter to transmit signals during the time interval with a spatial beam pattern associated with the channel estimates determined by said receiver.
