Abstract: Embodiments of the present disclosure provide a resource management method and a related device. The resource management method includes: receiving, by UE, signaling for releasing resource sent by a base station, where the signaling for releasing resource indicates information of resource location; and determining, based on the information of resource location, a time-frequency resource corresponding to the information of resource location in allocated resources already allocated by a network side to the UE, and then releasing the time-frequency resource. The UE may release some of the allocated resources based on an indication of the base station.

Abstract: Embodiments of the present disclosure provide a data transmission method and apparatus. The method includes sending, by a base station to UE, a downlink control channel used to schedule downlink data. The method further includes indicating, by the base station, a first time-frequency resource domain and a second time-frequency resource domain using the downlink control channel. A downlink data channel is sent on a time-frequency resource that is in the first time-frequency resource domain and that does not belong to the second time-frequency resource domain.
