发明名称 Adaptive uplink coordinated multipoint communication for backhaul
摘要 A method and system for adaptive coordinated multipoint support in a wireless communication system are disclosed. According to one aspect, the invention provides an uplink coordinated multipoint, CoMP, method. A CoMP request is received at a cooperating base station from a serving base station. The CoMP request specifies a first CoMP payload type. Responsive to receiving the CoMP request, a second type of CoMP payload to provide to the serving base station is provided. The second type of CoMP payload is determined based at least in part on resource usage. The cooperating base station provides a CoMP payload of the determined second CoMP payload type to the serving base station.

主权项 1. An uplink coordinated multipoint, UL-CoMP, method, comprising: receiving, at a cooperating base station, a UL-CoMP request from a serving base station, the UL-CoMP request requesting assistance from the cooperating base station, the UL-CoMP request specifying a first CoMP payload type; responsive to receiving the UL-CoMP request, determining a second type of CoMP payload type to provide to the serving base station based at least in part on a level of congestion on a backhaul link, the first CoMP payload type being one of: a time domain IQ, TD-IQ, samples payload;a frequency domain IQ, FD-IQ, samples payload;a log-likelihood ratio, LLR, payload; and a transport block, TB, payload; the determining including: determining that the second CoMP payload type is the TD-IQ payload type when the level of congestion is less than a first threshold;determining that the second CoMP payload type is the FD-IQ payload type when the level of congestion is less than a second threshold that is greater than the first threshold;determining that the second CoMP payload type is the LLR payload type when the level of congestion is less than a third threshold that is greater than the second threshold; anddetermining that the second CoMP payload type is the TB payload type when the level of congestion is greater than the third threshold; and providing a CoMP payload of the determined second CoMP payload type to the serving base station.
