Kind Code:
A1
Abstract:
Provided in the present application are a communication method, a communication apparatus and a system. The method comprises: a terminal device receives on a primary cell DCI sent by a network device, the DCI being used to instruct the terminal device to switch a secondary cell from dormant to non-dormant; and the terminal device determines, according to the time delay of BWP handover and first information, that the time interval K0 from the DCI to a PDSCH scheduled by the DCI or the time interval K2 from the DCI to a PUSCH is not shorter than a first time period. The delay of BWP handover comprises a first handover delay, the first handover delay is the delay of BWP handover by the secondary cell, and the duration of the first handover delay is N time units. The first information is used to indicate that there is no PDSCH within minK0 time units and/or no PUSCH within minK2 time units after the terminal device receives the DCI. The duration of the first time period is T1 time units, T1 being the larger value among N and minK0/minK2.
