Uplink transmitting power control method for carrier aggregation between base stations, base station, and equipment

Abstract

An embodiment of the present invention provides an uplink transmitting power control method for carrier aggregation between base stations, a base station, and equipment, wherein the method includes that a first base station acquires the maximum uplink transmitting power allocated by user equipment (UE) to the first base station; and the first base station configures the uplink transmitting power for the UE according to the maximum uplink transmitting power. The method provided by the present invention can coordinate the power allocated by the UE to each base station because the maximum transmitting power allocated to the first base station is allocated according to the uplink resource state information of a second base station, so that the first base station can accurately allocate the uplink transmitting power to the UE, and improves the throughput of the UE while satisfying the transmitting power requirements of multiple base stations. Since the uplink resource states configured by other base stations are considered between the base stations, the allocated uplink transmitting power can reduce or even avoid a waste phenomenon, thereby improving the transmission efficiency.

Description

technical field [0001] Embodiments of the present invention relate to wireless communication technologies, and in particular to an uplink transmit power control method, base station and equipment for carrier aggregation between base stations. Background technique [0002] With the development of mobile communication technologies, the 3rd Generation Partnership Project (the 3rd Generation Partnership Project, 3GPP for short) puts forward higher requirements on peak data rate and system bandwidth. In order to meet these requirements, 3GPP Long Term Evolution Advanced (LTE-A for short) introduces carrier aggregation (Carrier Aggregation, CA for short). CA can obtain larger bandwidth by aggregating multiple continuous or non-contiguous component carriers (Component Carrier, CC for short), so as to improve peak data rate and system throughput. In the carrier aggregation system, when a user equipment (User Equipment, UE) works on multiple carriers, the eNB is allowed to schedule ...

AI Technical Summary

Problems solved by technology

For inter-base station CA, after the PHR is triggered, the PHR sent by the UE in any serving cell can only be received by one of the base stations. The base station receiving the PHR does not know the uplink resource allocation of other base stations, and cannot coordinate the uplink resources of each serving cell.

As a result, the waste of transmission resources and the problem of low transmission efficiency
