Abstract

The invention relates to the communication field and discloses a method and a device for balancing control of a channel load. The method comprises the following steps that a base station divides all carriers into a low load group and a high load group according to channel quality information of each carrier, which is fed back by user equipment UE, and the number of UE for scheduling by utilizing a physical downlink control channel PDCCH of the carrier; the base station determines the number of UE which needs transfer on each carrier in the high load group and the number of UE which can be accepted on each carrier in the low load group; the base station selects one carrier in the low load group for the UE which needs transfer on each carrier in the high load group according to the number of the UE which needs transfer and the number of the UE which can be accepted; and the base station transfers the UE which needs transfer on each carrier in the high load group to the corresponding carrier in the low load group. The method and the device are used for solving the problem that in the prior art, the load balance of each carrier control channel is not considered so that resources of a control region cannot be effectively and reasonably employed.

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 data services in the future, the LTE-A (Long Term Evolution Advanced) and its subsequent evolution systems introduce a 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, when UE aggregates multi...
