Embodiment Construction

[0124] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to 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.

[0125] In the hybrid network of macro and micro stations, UEs (User Equipment, user equipment) in the Micro eNB (Micro evolved NodeB, micro station) cell are likely to cause interference to UEs in the Macro eNB (Macro evolved NodeB, macro station) cell. In this way, As a result, the SINR (Signal to Interference plus Noise Ratio, Signal to Interference Plus Noise Ratio) of the user equipment of the macro station is reduced, and the rate is reduced. The overall ...

Abstract

Embodiments of the present invention provide a power control method and device, which relate to the field of communications and can coordinate interference between user equipments and increase cell throughput. The method comprises: a base station receiving a power headroom report reported by a user equipment, and the base station obtaining a second transmit power headroom according to a first transmit power headroom in the power headroom report and a preset parameter, and then the base station performing power control on the user equipment according to a second transmit power headroom; or the base station sending a message to a user equipment through an air interface, the message comprising a preset parameter and the preset parameter being used for determining a second transmit power headroom of the user equipment, and then, the base station receiving a power headroom report reported by the user equipment, and performing power control on the user equipment according to the second transmit power headroom in the power headroom report. The embodiments of the present invention are used for power control in macro and micro networking.

Description

technical field [0001] The present invention relates to the communication field, in particular to a power control method and equipment. Background technique [0002] With the development of mobile broadband and the wide application of various smart terminals, the rapid growth of data services, even the LTE (Long Term Evolution, long-term evolution) network cannot fully meet the future mobile data needs, especially the capacity of hotspot areas, blind spots Coverage, indoor coverage, etc. will put forward higher requirements on the existing macro cellular architecture. The smallcell (microcellular) architecture has effectively improved the network capacity and coverage issues. Macro-micro co-frequency heterogeneous networking is currently an effective method to solve problems such as hotspot capacity and blind spot coverage. [0003] With the increasing popularity of macro and micro network construction methods, while bringing capacity gains, there is also a problem that can...
