Mobile device assisted coordinated multipoint transmission and reception

摘要

Idle mobile devices are used as cooperating devices to support coordinated multipoint transmission and reception for uplink and downlink communications between a primary mobile device and its serving base station. For uplink communications, the cooperating mobile devices receive the uplink transmission from the primary mobile device and retransmit the received data signal to the serving base station for the primary mobile device. For downlink communications, the cooperating mobile devices receive the downlink transmission from the serving base station and retransmit the received data signal to the primary mobile device.

主权项

1. A method of coordinated multipoint reception implemented by a primary mobile device, comprising:
receiving, by the primary mobile device, during one iteration of a hybrid automatic repeat request (HARQ) process, a first data signal transmitted by a serving base station; in response to an acknowledgement signal transmitted by the primary mobile device to the serving base station, receiving, by the primary mobile device, during a subsequent iteration of the HARQ process and in a subframe following a subframe that the first data signal is received, a second data signal transmitted by a cooperating mobile device in a coordinating set for the primary mobile device, wherein the second data signal comprises a retransmission of the first data signal; and combining the first and second data signals to produce a combined data signal.
