Embodiment Construction

[0038] Aiming at the problem that the uplink sounding reference signal SRS of each transmission point in the LTE heterogeneous network COMP interferes with each other and affects the quality of channel estimation between cells, the present invention proposes an uplink sounding reference signal configuration method for LTE heterogeneous network CoMP And an LTE heterogeneous network configured with an uplink sounding reference signal.

[0039] The present invention proposes an LTE heterogeneous network configured with uplink sounding reference signals, and its networking structure is as follows: figure 1 As shown, the macrocell base station in the LTE heterogeneous network and the low-power transmission nodes in the coverage area form a heterogeneous cell cluster, and the LTE heterogeneous network includes:

[0040] The base station uniformly configures the cell-level uplink sounding reference signal (SRS) of the CoMP cooperating set in the cluster, and uniformly configures the ...

Abstract

The invention provides a method for configuring up-going detection reference signals and a line termination equipment (LTE) heterogeneous network. A macro cell site of the LTE heterogeneous network and small power transmission nodes in the covering area of the LTE heterogeneous network form a heterogeneous small area cluster, a plurality of CoMP small areas in the heterogeneous small area cluster forms a CoMP cooperation collection for carrying out coordinated multipoint transmission for a same user terminal, area stage SRS resources of the CoMP area and user stage SRS resources of CoMP user experience design (UE) are uniformly configured by the macro cell site of a cluster, and thus the orthogonality of the CoMP UE and the CoMP, the CoMP UE and non-CoMP UE and the non-CoMP UE and the non-CoMP UE of the small area cooperation collection are achieved. According to the method for configuring the up-going detection reference signals and the LTE heterogeneous network, signal to interference plus noise ratio (SINR) of user SRS is improved, and interactive data quantity brought by coordinated SRS resource configuration of each small area is reduced.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to an uplink sounding reference signal configuration method for LTE heterogeneous network CoMP and an LTE heterogeneous network configured with uplink sounding reference signals, which can solve the problem that occurs when the LTE heterogeneous network executes CoMP The problem of mutual interference of uplink sounding reference signals. Background technique [0002] LTE heterogeneous networking generally refers to a networking method in which macro cells (Macro eNB) and low power transmission equipment (LPN: Low Power Node, such as micro cells, Pico, RRH, etc.) are deployed in an LTE network. The LTE heterogeneous network forms overlapping coverage by deploying several low-power transmission devices in the macro cell coverage area, which is used to solve the problem of weak coverage and capacity limitation in the macro cell coverage area. See figure 1 . [0003] In t...
