In one embodiment, an apparatus includes memory storing instructions and processing circuitry coupled to the memory. The processing circuitry is to implement the instructions to select a resource block group (RBG) size configuration from a set of RBG size configurations based on a bandwidth part (BWP) size. Each RBG size configuration is to indicate RBG sizes associated with respective ranges of BWP sizes, and the RBG sizes are to indicate a number of frequency-domain physical resource blocks (PRBs) for physical downlink shared channel (PDSCH) or physical uplink shared channel (PUSCH) transmissions. The processing circuitry is further to implement the instructions to allocate PRBs for communication between the gNB device and a user equipment (UE) device via the PDSCH or PUSCH transmissions based on the selected RBG size, and to encode downlink control information (DCI) that indicates the allocated PRBs for transmission to the UE device.

Provided are a method for selecting an initial bandwidth part (BWP), a terminal device and a network device. The method includes: determining, by a terminal device, a target initial BWP among a plurality of initial BWPs for a first cell according to measurement results of a plurality of reference signal beams in the first cell. Each initial BWP in the plurality of initial BWPs is associated with at least one reference signal beam, and the first cell is a cell which the terminal device currently camps on.

A method includes a first access network device that sends first indication information to a second access network device. The first indication information indicates information about a current active BWP and/or transmission rate information of a terminal device on the first access network device. The second access network device determines information about a first-time active BWP and/or BWP configuration information of the terminal device on the second access network device based on the first indication information. The method may be used to enable the second access network device to determine the appropriate information about the first-time active BWP and/or the appropriate BWP configuration information of the terminal device on the second access network device. In this way, service interruption caused by switching of an active BWP is reduced, and/or service interruption caused by changing of a BWP configuration is reduced.

The present disclosure relates to a pre-5.sup.th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4.sup.th-Generation (4G) communication system such as Long Term Evolution (LTE). Inter-cell coordinated transmission through a multi-transmission reception point (multi-TRP) in a wireless or communication system is described. A terminal receives configuration information related to a multi-TRP, checks whether inter-cell multi-TRP transmission is configured on the basis of the configuration information, based on the inter-cell multi-TRP transmission being configured, checks a control resource set (CORESET) for the multi-TRP on the basis of the configuration information, receives downlink control information (DCI) for the multi-TRP through the CORESET, and receives data from the multi-TRP on the basis of the DCI.
