Abstract

The embodiment of the invention provides a channel capacity control method and device. According to the embodiment of the invention, the utilization rate of the control channel element CCE in the cellis counted by the main cell; according to the utilization rate of the CCE, an aggregation level of the CCE, a target value of a block error rate BLER of a physical downlink control channel PDCCH andthe maximum lifting value of the transmitting power during emission of the CCE are determined and can be flexibly adjusted according to the utilization rate of the CCE, the situation that the experience of all users of the whole main cell is sharply reduced after the CCE resources are greatly occupied is avoided, meanwhile, the situation that the load of a PDCCH of the main cell is too high is avoided, and interference of the main cell to adjacent cells is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a channel capacity control method and device. Background technique [0002] The current physical downlink control channel (Physical Downlink Control Channel, PDCCH for short) resource allocation is based on the coverage strategy, which can guarantee the PDCCH resource of a single user. The PDCCH is a resource set composed of Control Channel Elements (CCE for short). [0003] However, when a large amount of traffic occurs in the primary cell, a large amount of control channel element (CCE) resources will be occupied, resulting in a sharp decline in the experience of all users in the entire primary cell. The load is too high, resulting in greater interference from the primary cell to neighboring cells. Contents of the invention [0004] Embodiments of the present invention provide a channel capacity control method and device, so as to avoi...
