Problems solved by technology

[0003] The downlink coverage adopts the method of fixedly setting power and MCS. When the group UE is close to the eNB, it may cause waste of downlink transmission power and radio bearer (Radio Bearer, RB) resource waste. When the group UE is far away from the eNB, It may also cause insufficient downlink coverage, and the effect of downlink coverage is poor.

Embodiment Construction

[0051] figure 1 It is a flowchart of a method for adaptive adjustment of downlink coverage of a trunking system according to the first embodiment of the present invention. Such as figure 1 As shown, the method includes the following processes.

[0052] Step 101: The group UE detects a downlink signal according to the acquired measurement configuration information.

[0053] In this step, the measurement configuration information includes: downlink signal measurement parameters and quality thresholds.

[0054] Step 102: When the measured value of the downlink signal measurement parameter is lower than the quality threshold, the group UE reports the downlink signal quality to the eNB.

[0055] In this step, when the measured value of the downlink signal measurement parameter is lower than the quality threshold, the group UE reports the downlink signal quality to the eNB, so that the eNB adjusts the downlink according to the number of group UEs that report the downlink signal quality obta...

Abstract

The invention provides a trunking system downgoing covering self-adaptive adjusting method, eNB and cluster user equipment (UE). The cluster UE detects downgoing signals according to obtained measurement configuration information which comprises downgoing signal measuring parameters and quality threshold. When a measuring value of the downgoing signal measuring parameters is lower than the quality threshold, the cluster UE reports downgoing signal quality to the eNB, and the eNB adjusts downgoing launching power and/or MCS according to the quantity of the cluster UE reporting downgoing signal quality, wherein the quantity of the cluster UE is obtained through statistics. By means of the trunking system downgoing covering self-adaptive adjusting method, the eNB and the cluster UE, downgoing covering can be adjusted in a self-adaptation mode according to the downgoing signal quality received by the cluster UE, and downgoing covering effect is improved.

Description

Technical field [0001] The present invention relates to mobile communication technology, in particular to a method for adaptive adjustment of downlink coverage of a trunking system, a base station (Evolution Node B, eNB for short) and a group user equipment (User Equipment, UE for short). Background technique [0002] In the Long Term Evolution (LTE) trunking system, cell-oriented point-to-multipoint group communication is usually performed in the downlink direction. In the existing LTE trunking system, there is no connection between the group UE and the eNB, and the eNB performs fixed settings for downlink coverage according to pre-configuration, including power settings and modulation and coding scheme (Modulation and Coding Scheme, MCS for short) settings. [0003] The downlink coverage adopts a fixed setting of power and MCS. When the group UE is close to the eNB, it may cause a waste of downlink transmission power and radio bearer (RB) resources, and when the group UE is far a...
