Abstract

The present invention relates to the field of communications, and discloses a method and device for balancing control channel loads, including: a base station according to the channel quality information of each carrier fed back by a user equipment UE, and a UE scheduled by using the physical downlink control channel PDCCH of the carrier Quantity, divide all carriers into low-load group and high-load group; determine the number of UEs that need to be transferred on each carrier in the high-load group, and determine the number of UEs that can be accommodated on each carrier in the low-load group; according to the needs The number of UEs to be transferred and the number of UEs that can be accommodated, select a carrier in a low-load group for UEs that need to be transferred on the carriers in each high-load group; transfer the UEs that need to be transferred on each carrier in the high-load group , transfer to the corresponding carrier in the low load group. The invention is used to solve the problem in the prior art that the load balance of the control channels of each carrier is not considered, and the resources in the control area cannot be effectively and rationally used.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for balancing control channel loads. Background technique [0002] With the continuous development of communication technology and the popularization of smart terminals, mobile broadband communication based on data services has become the trend of future mobile communication development. In order to meet the rapid development of future data services, LTE-A (Long Term Evolution Advanced) and its subsequent evolution systems introduce CA (Carrier Aggregation, Carrier Aggregation) technology. This technology allows UE (User Equipment, User Equipment) to simultaneously aggregate multiple carriers for its common service. Since the scheduling of PUSCH (Physical Uplink Shared Channel) and PDSCH (Physical Downlink Shared Channel) on different carriers requires PDCCH (Physical Downlink Control Channel) to indicate scheduling information, Therefore, when a UE aggregates mult...
