Example Embodiment

[0054] Hereinafter, we will describe the best implementation of the present invention in detail with reference to the accompanying drawings. First of all, it should be pointed out that the meanings of the terms, words and claims used in the present invention cannot be understood only by their literal and ordinary meanings, but also include meanings and concepts that are consistent with the technology of the present invention. This is because As inventors, we must give proper definitions of terms in order to best describe our invention. Therefore, the configuration given in this description and the drawings are only the preferred embodiments of the present invention, rather than enumerating all the technical characteristics of the present invention. We must realize that there are various equivalent or modified plans that can replace our plans.

[0055] The basic idea of ​​the present invention is to divide SRS resources into multiple SRS sub-resource sets in advance, each set has...

Abstract

The invention discloses a method, a device and a base station for distributing sounding reference signal (SRS) resource in a long term evolution (LTE) system. Before distributing SRS for user equipment (UE), uplink sounding reference signal information (SRS) is divided into a plurality of SRS secondary resources in advance, and a plurality of SRS secondary resource collections are formed, wherein the SRS secondary resources in the identical SRS secondary resource collections are provided with identical resource allocation. The method of distributing SRS resource includes the following steps of ascertaining the SRS secondary collections which are used for distributing the SRS resources for the UE according to access requirement information transmitted by the UE, and distributing the SRS secondary resources capable of being distributed in the ascertained SRS secondary collections to the UE. According to the method, the device and the base station for distributing (SRS) resource in the LTE system, complexity of distribution of the SRS resource can be reduced, search time capable of being used for the distribution of the resource can be shortened, and therefore time of the base station to distribute the SRS resource to the user equipment (UE) can be saved and distribution efficiency is improved.

Description

technical field [0001] The present invention relates to a TD-LTE communication system, in particular to a method, device and base station for allocating SRS resources in the LTE system. Background technique [0002] In the time-division long-term evolution system (TD-LTE system), the uplink sounding reference signal (SRS) is used to measure the quality of the uplink channel. Specifically, the use of SRS can realize frequency selective scheduling of user equipment (UE). frequency selection scheduling), power control and timing advance functions. There are two types of TD-LTE systems at present, which are indoor systems and outdoor systems. For an indoor system, the system function of the SRS is frequency selective scheduling; for an outdoor system, the system function of the SRS includes frequency selective scheduling and beamforming. [0003] The design of the SRS in the current protocol is relatively complicated. This is because, on the one hand, the impact of the SRS on ...
