Abstract: Embodiments of this application disclose a resource configuration method, apparatus, and system. A network device sends a resource configuration of a physical uplink control channel PUCCH used for beam failure recovery to a terminal device, where the resource configuration of the PUCCH includes a corresponding transmit beam of the PUCCH. When detecting a beam failure event, the terminal device sends a transmit beam failure recovery request to the network device based on the resource configuration of the PUCCH and a corresponding periodicity of the PUCCH. The periodicity of the PUCCH may be configured by the network device, or may be a preset periodicity. According to the configuration manner of the PUCCH resource used for beam failure recovery in the embodiments of this application, the terminal device can flexibly and effectively perform beam failure recovery.

Abstract: Embodiments provide a beam switching method and a related device. Under the method a first subframe sent by a base station by using a first beam can be received by a terminal device. The first subframe includes first-order downlink control information and second-order downlink control information. The terminal device can search for the second-order downlink control information based on the first-order downlink control information. The first-order downlink control information includes location indication information of the second-order downlink control information in the first subframe. The terminal device can switch from the first beam to a second beam based on the found second-order downlink control information to receive a second subframe. The downlink control information includes a switching indication field of the second beam. In this way, flexibility of beam switching is improved, load balancing of a control channel is implemented, and a latency of beam switching is reduced.

Abstract: This application provides a method and an apparatus for determining a cell activation delay. A terminal device or a network device may determine the cell activation delay corresponding to a to-be-activated cell based on that a downlink spatial filter of a downlink signal of the to-be-activated cell and a downlink spatial filter of a downlink signal of an activated cell are the same or different. In this way, the terminal device sends CSI within the activation delay. The network device is to receive the CSI within the activation delay, and determines, depending on whether the CSI is received, whether the to-be-activated cell is successfully activated, the terminal device and the network device can determine a proper activation delay, to avoid a case in which the terminal device and the network device mistakenly determine, due to an excessively long or excessively short activation delay, whether a secondary cell is successfully activated.
