In dynamic spectrum sharing between a first radio access type and a second radio access type, information indicating indirectly whether a minimum resources are reserved for downlink reference transmissions of the first radio access type, is used to determine in devices rate matching scheme to be used, or to determine resources which can be used.

A bandwidth mode indication method and apparatus are provided, and relate to the field of communication technologies. The method includes: A transmit end sends a first frame to a receive end, where the first frame includes a service field, the service field includes a first field, the first field indicates whether a bandwidth mode indication field carried in the first frame is allowed to indicate a target bandwidth mode, and the target bandwidth mode includes one or more of bandwidth modes other than 20 MHz, 40 MHz, 80 MHz, and 80+80 MHz or 160 MHz.

A communication control method is used in a mobile communication system for providing a multicast broadcast service (MBS). The communication control method includes transmitting, by a base station, MBS data to user equipment in a first cell, transmitting, by the base station to the user equipment, a notification message indicating that an MBS cell being a cell used to transmit or receive the MBS data is to be changed from the first cell to a second cell, and receiving, by the user equipment configured to receive the MBS data from the base station, the notification message from the base station.

A communication method and an apparatus. A terminal device camps on a first BWP, where the terminal device is in a non-connected state. The terminal device receives a first message from a network device, where the first message is for indicating a second BWP; and the terminal device switches from the first BWP to the second BWP.

A method and apparatus are provided, in which information of a frequency domain resource of a control resource set of an active downlink bandwidth part and information of a search space set associated with the control resource set are received (302). A frequency location of the control resource set is determined (304) at a physical downlink control channel monitoring occasion of the search space set based on the information of the frequency domain resource and information of frequency hopping of the control resource set. Blind decoding of physical downlink control channel candidates is performed (306) based on the determined frequency location of the control resource set at the physical downlink control channel monitoring occasion.

A base station belonging to a first cell group (CG) that includes a transceiver configured to connect to a user equipment (UE) and a processor configured to transmit a command to the UE to perform a BWP switch, and monitor a physical uplink control channel (PUCCH) for an acknowledgement or a negative acknowledgement (ACK/NACK) for a predetermined period of time, wherein the predetermined period of time is the sum of a standard-defined period of time between transmission of a radio resource control (RRC) command and receipt of the ACK/NACK, a time to process an RRC command, and a time to perform a BWP switch.
