Abstract

The invention provides a method for adjusting the CCE (control channel element) aggregation level in a cluster service, a base station and a monitoring terminal. The method comprises the steps that the base station sends group signaling to a group in a periodic mode, wherein the group signaling carries configuration information used for indicating the monitoring terminal to configure SR (scheduling request) resources in a PUCCH (physical uplink control channel); a first time, which is acquired by calculating in the current period, of DCI (downlink control information) sent to the group is sent to the monitoring terminal, thereby enabling the monitoring terminal to report SR signals to the base station on the SR resources when a second time calculated in the current period of the received DCI is less than the first time, wherein the monitoring terminal is located at an uplink self-synchronization state, the base station detects whether the SR signals are received on the SR resources, the aggregation level of a CCE is up-regulated to a target aggregation level from the current aggregation level if the SR signals are detected on the SR resources, and the DCI is sent to the group according to the target aggregation level of the CCE in the next period. The base station flexibly adjusts the aggregation level of the CCE according to the SR signals fed back by the monitoring terminal.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for adjusting CCE aggregation levels in trunking services, a base station and a monitoring terminal. Background technique [0002] The main feature of the trunking service is that one speaker terminal speaks, and multiple monitoring terminals are listening, and each terminal in the trunking service may be in multiple cells, or may be in the same cell. In the same cell, only one terminal is used as the speaker terminal, and the other terminals are listener terminals. This is called a group in the trunking service. [0003] For a non-cluster service, the base station configures a scheduling request (SchedulingRequest, SR for short) resource for a terminal in a connected state. When the terminal has uplink data to be uploaded, it sends an uplink scheduling request to the base station through the SR resource. A group in the trunking service only has downlink services, and cannot ...
