Embodiment Construction

[0016] Therefore, the present invention aims to provide a new signaling and procedure to support the configuration of ABS with reduced transmission power on a macro cell.

[0017] In the following, two different signaling modes supporting ABS with reduced transmission power on a macro cell according to specific embodiments of the present invention will be specifically introduced for inter-cell interference coordination (ICIC). One way is a dynamic working mechanism based on data channel transmission power, which is configured by PDCCH signaling and defined in a data control information (Data Control Information, DCI) format. Another way is based on a semi-static working mechanism configured by RRC signaling. Hereinafter, the corresponding signaling and procedures of the two modes will be described in detail.

[0018] For transmission mode 1 (TransmissionMode1, TM1) to transmission mode 6 (TransmissionMode6, TM6), the user terminal sets the parameter P A Serves as a reference...

Abstract

The invention provides a method in a macrocell base station in a wireless communication network for indicating a user terminal governed by the macrocell base station to regulate macrocell almost blank subframe transmission power accepted by the user terminal. The method includes the following steps: sending first power regulation indication information to the user terminal, and sending second power regulation indication information to the user terminal, wherein the second power regulation indication information is used for indicating difference between each source energy of a physical downlink shared channel of an almost blank subframe of the macrocell accepted by the user terminal and each source energy of a cell specific reference channel of the almost blank subframe of the user terminal.

Description

technical field [0001] The present invention relates to a wireless communication network, in particular to a method and a device for adjusting the ABS transmission power of a macro cell considered by a UE. Background technique [0002] In the discussion of Heterogeneous network (HetNet) eICIC of 3GPPL TERel-10, an almost blank subframe (Almost Blank Subframe, ABS) with reduced power or reduced activity is applied in a macro cell (Macrocell) to alleviate the (Picocell) interference. The so-called heterogeneous network refers to a network that includes various base stations (such as macro base stations and other microcell base stations, etc.), and the areas covered by these base stations overlap at least partially. A macrocell is a network that provides wireless coverage served by high-power cellular base stations. The so-called small cell usually covers a small area in a heterogeneous network, for example, in a room (office, shopping plaza, station, etc.). In a cellular ne...
