Abstract
This application provides an information indication method and apparatus for a non-terrestrial communication network. The method includes: A terminal receives first indication information, where the first indication information includes a bandwidth part BWP indication field, and the BWP indication field indicates a BWP identifier offset; the terminal determines a second bandwidth part identifier BWP_ID based on the BWP identifier offset, where the second BWP_ID corresponds to a target beam of the terminal; and the terminal switches to the target beam. The method extends indication of BWP identifiers on a premise of compatibility with indication based on conventional downlink control information DCI.
Claims20
An information indication method, wherein the method comprises:
- receiving, by a terminal, first indication information, wherein the first indication information comprises a bandwidth part (BWP) indication field, and the BWP indication field indicates a BWP identifier offset;
- determining, by the terminal, a second bandwidth part identifier BWP_ID based on the BWP identifier offset, wherein the second BWP_ID corresponds to a target beam of the terminal;
- and
- switching, by the terminal, to the target beam.
An information indication method, wherein the method comprises:
- sending, by a network device, a first bandwidth part identifier (BWP_ID), wherein the first BWP_ID corresponds to a current serving beam of a terminal;
- and
- sending, by the network device, first indication information, wherein the first indication information comprises a bandwidth part (BWP) indication field, the BWP indication field indicates a BWP identifier offset, and the BWP identifier offset indicates an offset value of an identifier of a target beam of the terminal relative to the first BWP_ID.
A communication apparatus, wherein the apparatus comprises a processor and a transceiver, and the processor is electrically coupled to the transceiver;
- the transceiver is configured to receive first indication information, wherein the first indication information comprises a bandwidth part (BWP) indication field, and the BWP indication field indicates a BWP identifier offset;
- and
- the processor is configured to determine a second bandwidth part identifier (BWP_ID) based on the BWP identifier offset, wherein and the second BWP_ID corresponds to a target beam of the terminal;
- and
- the processor is configured to switch to the target beam.
