US 11,889,473 B2 · Resource switching method, and resource allocation method, apparatus, device and system

Abstract

The present disclosure relates to the technical field of communications, and disclosed thereby are a resource switching method and a resource allocation method, apparatus, device and system. The method comprises: when a terminal determines that a first BWP currently used needs to be switched, the terminal selects a second BWP among at least two BWPs configured in advance; and the terminal switches from the first BWP to the second BWP. By means of the present disclosure, a terminal may autonomously configure and switch BWPs without needing an access network device to specify the BWP for the terminal, and the BWP may be introduced into a communication system supporting large bandwidth such as D2D, thus reducing the power consumption of the terminal within the communication system, and ensuring that the communication of the terminal is effective by switching the BWP in time.

Claims17

Dependent claims

A method for resource switching, comprising:

obtaining, by a terminal, present communication status information;
responsive to the present communication status information not matching a first bandwidth part (BWP) presently used by the terminal, determining, by the terminal, that it is necessary to switch the first BWP presently used;
responsive to the terminal determining that it is necessary to switch the first BWP presently used, selecting, by the terminal, a second BWP among at least two pre-configured BWPs, comprising:
determining, by the terminal, configuration information of a BWP to be switched to based on the present communication status information, wherein the configuration information comprises at least one of:
a bandwidth, a subcarrier spacing, a type of a cyclic prefix (CP) or a pilot configuration;
and
searching, by the terminal, for a BWP matching the configuration information among the at least two pre-configured BWPs, and determining the BWP as the second BWP;
and
switching, by the terminal, from the first BWP to the second BWP.

A method for resource configuration, comprising:

obtaining, by a terminal, at least one pre-configured bandwidth part (BWP) set, wherein each of the at least one pre-configured BWP set comprises at least one BWP;
selecting, by the terminal, a BWP set from the at least one pre-configured BWP set;
and
selecting, by the terminal, a first BWP from the BWP set, comprising:
obtaining, by the terminal, present communication status information;
determining, by the terminal, configuration information of a BWP to be selected based on the present communication status information, wherein the configuration information comprises at least one of:
a bandwidth, a subcarrier spacing, a type of a cyclic prefix (CP) or a pilot configuration;
and
searching, by the terminal, for a BWP matching the configuration information from the BWP set, and determining the BWP as the first BWP;
wherein the method further comprises:
when the BWP set selected by the terminal comprises at least two BWPs, and it is determined that it is necessary to switch the first BWP presently used, selecting, by the terminal, a second BWP from the BWP set;
and switching, by the terminal, from the first BWP to the second BWP.
