Abstract

This application provides a method for managing an antenna panel, a network device, and a terminal device. The method includes: a network device receives capability information that is of an antenna panel and that is from a terminal device, and sends an activation command and/or a deactivation command to the terminal device, so that the terminal device performs a corresponding operation. In embodiments of this application, the network device assists the terminal device in managing an antenna panel, so that the terminal device can better manage the antenna panel, thereby reducing overheads of the terminal device.

First claim

1 . A method for managing an antenna panel comprising:
receiving, by a network device, from a terminal device, capability information of an antenna panel of the terminal device; and sending, by the network device, first indication information to the terminal device, wherein the first indication information indicates the terminal device to activate and/or deactivate one or more antenna panels.

2 . The method according to claim 1 , wherein the first indication information indicates the terminal device to activate one or more first antenna panels, by carrying information required for activating the one or more first antenna panels; and/or
wherein the first indication information indicates the terminal device to deactivate one or more second antenna panels, by carrying information required for deactivating the one or more second antenna panels.

3 . The method according to claim 1 , further comprising:
sending, by the network device, first resource configuration information to the terminal device, wherein the first resource configuration information is used to configure one or more reference signal resource sets, and each reference signal resource set is associated with one antenna panel.

4 . The method according to claim 1 , wherein in response to the first indication information indicating the terminal device to activate the one or more first antenna panels, the method further comprises:
sending, by the network device, first time information to the terminal device, wherein the first time information indicates that the terminal device is to keep the one or more first antenna panels in an active state after a first time ends.

5 . The method according to claim 1 , wherein in response to the first indication information indicating the terminal device to activate the one or more first antenna panels, the method further comprises:
indicating, by the network device to the terminal device, duration for keeping the one or more first antenna panels activated.

6 . The method according to claim 1 , wherein in response to the first indication information indicating the terminal device to deactivate the one or more second antenna panels, the method further comprises:
sending, by the network device, second time information to the terminal device, wherein the second time information indicates that the terminal device deactivates the one or more second antenna panels after a second time.

7 . The method according to claim 1 , wherein in response to the first indication information indicating the terminal device to deactivate the one or more second antenna panels, the method further comprises:
indicating, by the network device to the terminal device, duration for keeping the one or more second antenna panels deactivated.

8 . A method for managing an antenna panel comprising:
sending, by a terminal device, capability information to a network device; receiving, by the terminal device, first indication information from the network device, wherein the first indication information indicates the terminal device to activate and/or deactivate one or more antenna panels; and activating and/or deactivating, by the terminal device, the one or more antenna panels based on the first indication information.

9 . The method according to claim 8 , wherein in response to the first indication information indicating the terminal device to activate one or more first antenna panels, and carrying information required for activating the one or more first antenna panels, the terminal device activates the one or more first antenna panels; and/or
in response to the first indication information indicating the terminal device to deactivate one or more second antenna panels, and carrying information required for deactivating the one or more second antenna panels, the terminal device deactivates the one or more second antenna panels.

10 . The method according to claim 8 , further comprising:
receiving, by the terminal device, first resource configuration information from the network device, wherein the first resource configuration information is used to configure one or more reference signal resource sets, and each reference signal resource set is associated with one antenna panel.

11 . The method according to claim 8 , wherein in response to the first indication information indicating the terminal device to activate the one or more first antenna panels, the method further comprises:
obtaining, by the terminal device, first time information, wherein the first time information indicates that the terminal device is to keep the one or more first antenna panels in an active state after a first time ends; and keeping, by the terminal device, the one or more first antenna panels in the active state after the first time ends.

12 . The method according to claim 8 , wherein in response to the first indication information indicating the terminal device to activate the one or more first antenna panels, the method further comprises:
obtaining, by the terminal device, duration for keeping the one or more first antenna panels activated; and keeping, by the terminal device, the active state of the one or more first antenna panels within the duration.

13 . The method according to claim 8 , wherein in response to the first indication information indicating the terminal device to deactivate the one or more second antenna panels, the method further comprises:
obtaining, by the terminal device, second time information, wherein the second time information indicates that the terminal device deactivates the one or more second antenna panels after a second time; and performing, by the terminal device, a deactivation operation on the one or more second antenna panels after the second time.

14 . The method according to claim 8 , wherein in response to the first indication information indicating the terminal device to deactivate the one or more second antenna panels, the method further comprises:
obtaining, by the terminal device, duration for keeping the one or more second antenna panels deactivated; and during a performance of deactivating the one or more second antenna panels, keeping, by the terminal device, an inactive state of the one or more second antenna panels within the duration.

15 . A terminal device comprising:
a transmitter, configured to cooperate with a processor to send capability information to a network device; a receiver, configured to cooperate with the processor to receive first indication information that is from the network device, wherein the first indication information indicates the terminal device to activate and/or deactivate one or more antenna panels; and the processor, configured to: activate and/or deactivate the one or more antenna panels based on the first indication information.

16 . The terminal device according to claim 15 , wherein the processor is configured to: if the first indication information indicates the terminal device to activate one or more first antenna panels, and carries information required for activating the one or more first antenna panels, activate the one or more first antenna panels; and/or
if the first indication information indicates the terminal device to deactivate one or more second antenna panels, and carries information required for deactivating the one or more second antenna panels, deactivate the one or more second antenna panels.

17 . The terminal device according to claim 15 , wherein the receiver is further configured to cooperate with the processor to:
receive first resource configuration information from the network device, where
