Embodiment Construction

[0024] Embodiments of the present invention provide a cell SRS resource allocation method and device. The cell SRS resource pool is divided into a periodic SRS resource pool and an aperiodic SRS resource pool in advance. When resources need to be allocated to a UE, according to the SRS trigger condition of the UE, Determine the resources required by the UE. When the SRS resources required by the UE are periodic SRSs, allocate SRS resources to the UE from the predetermined periodic SRS resource pool; SRS resources are allocated to the UE in the determined aperiodic SRS resource pool, thereby avoiding resource conflicts caused when periodic SRS resources and aperiodic SRS resources are allocated in the cell SRS resource pool at the same time, and improving the utilization rate of SRS resources.

[0025] Such as figure 1 As shown, the cell SRS resource allocation method provided by the embodiment of the present invention includes:

[0026] Step S101, when it is determined that SRS...

Abstract

The invention discloses an allocation method and device for community SRS resources. Periodic SRS resources and non-periodic SRS resources are preserved respectively, so that a community SRS resource pool is divided into a periodic SRS resource pool and a non-periodic SRS resource pool. When user equipment (UE) needs to be allocated with resources, available resources are selected in a corresponding resource pool according to SRS triggering conditions of the UE. When the SRS resources needed by the UE are periodic SRS resources, the UE is allocated with the SRS resources from the predesigned periodic SRS resource pool; and when the SRS resources needed by the UE are non-periodic SRS resources, the UE is allocated with the SRS resources from the predesigned non-periodic SRS resource pool, accordingly, the resource conflict problem of periodic SRS and non-periodic SRS resource alternative allocation caused by access orders and the like of the UE is avoided, the fairness of SRS resource allocation to the UE is guaranteed, and the distribution success rate of the SRS resources is improved.

Description

technical field [0001] The present invention relates to communication technology, in particular to a cell SRS resource allocation method and device. Background technique [0002] In an LTE (Long Term Evolution, Long Term Evolution) system, uplink channel information is measured through an uplink pilot reference signal SRS (Sounding Reference Signal, Sounding Reference Signal). [0003] In the LTE R8 / 9 system, the SRS transmission resource of the UE (User's Equipment, user equipment) is quasi-statically configured through RRC (Radio Resource Control, radio resource control) signaling, and the SRS transmission is a single-port SRS, and the UE follows the high-layer signaling SRS is sent periodically. In the LTE-A (Long Term Evolution Advanced, Advanced Long Term Evolution) R10 system, due to the introduction of features such as uplink MIMO (Multiple Input Multiple Output, Multiple Input Multiple Output), UE often needs to transmit SRS on multiple ports, SRS resource requireme...
