Abstract

Embodiments of the present invention provide a method and device for adjusting a CCE aggregation level of a control channel unit. The method includes: determining the CCE occupancy rate of the control channel unit in each time slot of the cell where the terminal is located; according to the CCE occupancy rate and a preset occupancy rate threshold, determining the The first parameter and the second parameter of the CCE occupancy rate; if the target spectral efficiency of the terminal is greater than or equal to the spectral efficiency threshold, and the first parameter is greater than or equal to the preset first parameter threshold, the physical The CCE aggregation level of the downlink control channel PDCCH is reduced to the first preset level; if the target spectral efficiency is less than the spectral efficiency threshold, and the second parameter is less than the preset second parameter threshold, aggregate the CCE of the PDCCH of the terminal Level up by the second preset level. The invention solves the problem in the prior art that the CCE aggregation level is adjusted through the MCS level, which affects the utilization of PDCCH resources.

Description

technical field [0001] The present invention relates to the technical field of mobile communications, and in particular, to a method and device for adjusting a CCE aggregation level of a control channel element. Background technique [0002] In a wireless communication system, a Physical Downlink Control Channel (PDCCH) carries functions such as scheduling and resource allocation information of a terminal (User Equipment, UE). In the 5G New Radio (NR) protocol, one PDCCH can be transmitted on n consecutive Control Channel Elements (CCEs), and each CCE consists of 12 Resource Element Groups (REGs). . [0003] The aggregation level represents the number of CCEs occupied by a PDCCH, that is, the PDCCH can use the CCE aggregation level to represent the occupied control resources. Generally, the higher the CCE aggregation level of a PDCCH, the better its demodulation performance, but the more control resources it occupies; in multi-user testing, the PDCCH resources are likely t...
