Abstract:
The present invention relates to a base station, a small cell, and a method for scheduling a communications link resources. A first small cell reports load information and channel state information of a channel between the first small cell and a neighboring second small cell to a base station. The first small cell receives link pre-scheduling signaling from the base station. The link pre-scheduling signaling includes wireless resource occupation information that indicates an occupancy of a wireless resource of the first small cell by a backhaul link. The first small cell allocates a first wireless resource in available wireless resources to the backhaul link according to the channel state information and the wireless resource occupation information, and allocates a second wireless resource in the remaining available wireless resources to an access link used for data transmission between the first small cell and a user equipment device.

Embodiments of the present invention provide an uplink control information feedback method, a base station, and a user equipment. The method includes: receiving uplink scheduling information of a non-independent small base station; and sending uplink control information (UCI) over a physical uplink shared channel (PUSCH) of the non-independent small base station according to the uplink scheduling information. In the embodiments of the present invention, the user equipment uses the physical uplink shared channel of the small base station to offload traffic from the physical uplink control channel (PUCCH), thereby reducing the load of the physical uplink control channel of the macro base station and reducing the collision probability.
