## Abstract

A bandwidth part processing method is provided. The method comprises: a terminal device receiving control information; and the terminal device deactivating and/or activating a bandwidth part on the basis of the control information. Also disclosed are another bandwidth part processing method, a terminal device, a network device and a storage medium.

## Claims

### Claim 1

A method for processing Bandwidth Parts (BWPs), comprising:
receiving, by a terminal device, Downlink Control Information (DCI), the DCI carrying indication information; and
performing, by the terminal device, activation processing on a second BWP and deactivation processing on a first BWP based on an information field of the indication information;
wherein the indication information comprises first indication information, the first indication information comprises a first information field, the first information field is 1-bit, and the terminal device performs activation processing on the second BWP and deactivation processing on the first BWP based on a value of the first information field;
wherein performing, by the terminal device, activation processing on the second BWP and deactivation processing on the first BWP based on the information field of the indication information comprises:
if the first information field is a first value, performing, by the terminal device, deactivation processing on the first BWP when activating the second BWP;
wherein the second BWP comprises a plurality of BWPs, and performing activation processing on the second BWP comprises activating the plurality of BWPs simultaneously; and
wherein the first BWP comprises a plurality of BWPs, and performing deactivation processing on the first BWP comprises deactivating the plurality of BWPs simultaneously.

### Claim 2 (depends on 1)

The method of claim 1, wherein performing deactivation processing on the first BWP comprises:
performing deactivation processing on the first BWP meeting a deactivation condition.

### Claim 3

A method for processing a Bandwidth Parts (BWPs), comprising:
sending, by a network device, Downlink Control Information (DCI), the DCI carrying indication information, and an information field of the indication information being configured for a terminal device to perform activation processing on a second BWP and deactivation processing on a first BWP;
wherein the indication information comprises first indication information, the first indication information comprises a first information field, the first information field is 1-bit, and a value of the first information field is configured to indicate that deactivation processing is performed on the first BWP when activating the second BWP;
wherein the second BWP comprises a plurality of BWPs, and the plurality of BWPs are activated simultaneously; and
wherein the first BWP comprises a plurality of BWPs, and the plurality of BWPs are deactivated simultaneously.

### Claim 4

A terminal device, comprising a memory, a transceiver and a processor, wherein
the memory is configured to store a software program capable of running on the processor; and
the transceiver is configured to receive Downlink Control Information (DCI), the DCI carrying indication information; and
the processor is configured to perform activation processing on a second Bandwidth Part (BWP) and deactivation processing on a first BWP based on an information field of the indication information;
wherein the indication information comprises first indication information, the first indication information comprises a first information field, the first information field is 1-bit, and the processor is configured to perform activation processing on the second BWP and deactivation processing on the first BWP based on a value of the first information field;
wherein the processor is configured to, if the first information field is a first value, perform deactivation processing on the first BWP when activating the second BWP;
wherein the second BWP comprises a plurality of BWPs, and performing activation processing on the second BWP comprises activating the plurality of BWPs simultaneously; and
wherein the first BWP comprises a plurality of BWPs, and performing deactivation processing on the first BWP comprises deactivating the plurality of BWPs simultaneously.

### Claim 5 (depends on 4)

The terminal device of claim 4, wherein the processor is configured to
perform deactivation processing on the first BWP meeting a deactivation condition.

### Claim 6

A network device, comprising a memory, a transceiver and a processor, wherein
the memory is configured to store a software program capable of running on the processor; and
the transceiver is configured to send Downlink Control Information (DCI), the DCI carrying indication information, and an information field of the indication information being configured for a terminal device to perform activation processing on a second Bandwidth Part (BWP) and deactivation processing on a first BWP;
wherein the indication information comprises first indication information, the first indication information comprises a first information field, the first information field is 1-bit, and a value of the first information field is configured to indicate that deactivation processing is performed on the first BWP when activating the second BWP;
wherein the second BWP comprises a plurality of BWPs, and the plurality of BWPs are activated simultaneously; and
wherein the first BWP comprises a plurality of BWPs, and the plurality of BWPs are deactivated simultaneously.
