Embodiment Construction

[0048] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0049] CoMP communication utilizes the collaboration between geographically separated multiple network elements to communicate with the UE, including coordinated multi-point transmission and / or coordinated multi-point reception, and transforms the interference between cells into expectations through joint processing (JP: Joint Processing) signals, or through coordinated scheduling / beamforming (CS / CB: Coordinated Scheduling / Coordinated Beamforming) to avoid confli...

Abstract

The invention discloses a coordinated multi-point communication power headroom reporting method and device. The method comprises that user equipment obtains an uplink coordinated multi-point (CoMP) measurement set configured by a serving base station, and the uplink CoMP measurement set contains measurement configuration information of a receiving point (RP); the user equipment estimates the downlink loss according to the uplink CoMP measurement set; and the user equipment generates a power headroom report (PHR) according to the downlink loss and reports the PHR to the serving base station. By employing the above method and device, the user equipment can estimate the downlink loss, PUSCH / PUCCH transmitting power and PH more accurately, the uplink resource can be distributed more accurately, interference is reduced, and the uplink throughput can be increased.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method and device for power headroom report (Power headroom report, PHR) of coordinated multi-point (coordinated multi-point, CoMP) communication. Background technique [0002] In the 3rd Generation Partnership Project (3rd Generation Partner Project, 3GPP) long term evolution (long term evolution, LTE) and advanced long term evolution (LTE advanced, LTE-A), the power headroom reporting process refers to the user equipment (User Equipment , user equipment) to the serving base station (serving base station) to report the difference information between the nominal maximum transmit power of the user equipment on each activated serving cell and the estimated transmit power on the uplink shared channel (uplink shared channel, UL-SCH), and at the same time During the power headroom reporting process, the user equipment also reports to the serving base station inf...
