Transceiver and a repeater

摘要

The invention discloses a transceiver (210, 215; 305, 310, 320, 330) for use in a cellular communications system (200, 300), arranged to communicate with at least one other transceiver in the system by means of technology for Multiple Input Multiple Output, MIMO. The transceiver is also arranged to control the function of a repeater (206, 207, 208, 209; 340) which is arranged to forward communication between the transceiver and said at least one other transceiver, said control being carried out as a result of measured performance parameters of the communication between the transceiver and said at least one other transceiver. In one embodiment, the function in the repeater (206, 207, 208, 209; 340) which the transceiver is arranged to control comprises activation and deactivation of the repeater.

主权项

1. A transceiver for use in a cellular communications system, the transceiver being arranged to:
communicate with at least one other transceiver in said system by means of technology for Multiple Input Multiple Output; activate a first subset of a plurality of repeaters, wherein the first subset of the plurality of repeaters are activated upon determining that the first subset of repeaters:
(i) fulfils a predetermined requirement for capacity or throughput, or(ii) maximize capacity or throughput, or(iii) has a composite channel path gain which exceeds a predetermined threshold; and control the activated first subset of repeaters arranged to forward communication between the transceiver and said at least one other transceiver, said control being carried out as a result of measured performance parameters of the communication between the transceiver and said at least one other transceiver, wherein the transceiver is operable to control one or both of the amplitude and phase of a signal transmitted by each repeater in the first subset that corresponds to a signal transmitted by the transceiver.
