Problems solved by technology

This method of statically configuring SRS resources for CoMP UEs will significantly reduce the available SRS resources for non-CoMP UEs, thereby affecting the utilization of SRS resources and further affecting the user capacity supported by SRS
[0007] To sum up, the existing technology cannot completely avoid the problem that the SRS signal of the CoMP UE is interfered by the coordinated cell, and affects the utilization rate of the SRS resource, thereby reducing the number of users supported by the SRS resource and reducing the system performance.

Embodiment Construction

[0060] Embodiments of the present invention provide a sounding reference signal SRS resource allocation method and device, which reasonably allocate SRS resources for CoMP UEs and non-CoMP UEs through preset resource allocation rules, and realize the orthogonality between SRS resources of different UEs. Furthermore, the problem that the SRS signal of the downlink CoMP UE is interfered by the coordinated cell is solved, and at the same time, due to the rational allocation of SRS resources, the utilization rate of the SRS resources is improved, thereby improving the downlink CoMP performance.

[0061] Such as figure 2 As shown, the embodiment of the present invention provides a sounding reference signal SRS resource allocation method, the method includes:

[0062] S21. Determine a first SRS resource group and a second SRS resource group shared between the serving cell and the coordinated cell;

[0063] S22. According to a preset resource allocation rule, allocate unallocated S...

Abstract

The invention provides a detection reference signal SRS resource allocation method and device. The method and device are used for preventing an SRS of downlink CoMP UE from being interfered by a cooperative cell, improving the utilization rate of SRS resources and further improving downlink CoMP performance. The method includes the steps of determining a first SRS resource group and a second SRS resource group shared between a service cell and the cooperative cell, allocating unallocated SRS resources in the first SRS resource group for the coordinated multiple points (CoMP) user equipment (UE) according to a preset resource allocation rule, and allocating unallocated SRS resources in the second SRS resource group for non-CoMP UE.

Description

technical field [0001] The present invention relates to the communication field, in particular to a sounding reference signal SRS resource allocation method and device. Background technique [0002] In the Long Term Evolution (LTE) system, both the downlink data transmission and the uplink data transmission adopt an orthogonal multiple access method based on Orthogonal Frequency Division Multiplex (OFDM). In the process of frequency networking, the ability of the serving cell to receive the signal sent by its user equipment (User Equipment, UE), or the ability of the UE to receive the signal sent by its serving cell will be interfered by the coordinated cell. 3GPP introduces a coordinated multiple point (Coordinated Multiple Points, CoMP) technology in the R11 release. [0003] In downlink CoMP, the SRS signal sent by the CoMP UE is received in the serving cell and the coordinated cell at the same time, because the SRS resources of the CoMP UE and the SRS resources of the U...
