Abstract

A wireless communication method, a terminal device and a network device. The method includes canceling or suspending, by a terminal device, an operation of Beam Failure Recovery (BFR) corresponding to a first secondary cell in response to deactivation of the first secondary cell.

First claim

What is claimed is:

1 . A wireless communication method, comprising:
canceling or suspending, by a terminal device, an operation of Beam Failure Recovery (BFR) corresponding to a first secondary cell in response to deactivation of the first secondary cell.

2 . The method according to claim 1 , further comprising:
deactivating, by the terminal device, the first secondary cell according to deactivation signaling from a network device or a deactivation timer for the first secondary cell.

3 . The method according to claim 1 , wherein canceling or suspending, by the terminal device, the operation of BFR corresponding to the first secondary cell comprises:
at a physical layer, stopping, by the terminal device, measuring a beam failure detection reference signal resource corresponding to the first secondary cell.

4 . The method according to claim 3 , further comprising:
at a Media Access Control (MAC) layer, notifying by the terminal device the physical layer to stop measuring the beam failure detection reference signal resource.

5 . The method according to claim 1 , wherein canceling or suspending, by the terminal device, the operation of BFR corresponding to the first secondary cell comprises:
at a physical layer, stopping by the terminal device, reporting a measurement status of a beam failure detection reference signal resource corresponding to the first secondary cell to a Media Access Control (MAC) layer; and/or at the MAC layer, stopping by the terminal device, receiving the measurement status of the beam failure detection reference signal resource corresponding to the first secondary cell reported by the physical layer.

6 . The method according to claim 1 , wherein canceling or suspending, by a terminal device, the operation of BFR corresponding to the first secondary cell comprises:
suspending or resetting, by the terminal device, counting of beam failure instances corresponding to the first secondary cell.

7 . The method according to claim 6 , wherein resetting the counting of the beam failure instances comprises: setting a count value of the beam failure instances to zero.

8 . The method according to claim 1 , wherein canceling or suspending, by the terminal device, the operation of BFR corresponding to the first secondary cell comprises:
stopping, by the terminal device, monitoring of a response of a network device for first information reported by the terminal device.

9 . The method according to claim 8 , wherein the first information is transmitted by Media Access Control Control Element (MAC CE).

10 . The method according to claim 9 , wherein the first information is used to indicate at least one of the following:
a beam failure, identity information of a cell where the beam failure occurs, and identity information of a candidate beam selected by the terminal device.

11 . The method according to claim 10 , wherein the beam failure indicates that a link quality of at least one secondary cell satisfies a second condition.

12 . The method according to claim 11 , wherein the second condition comprises that a cumulative number of beam failure instances corresponding to the at least one secondary cell is greater than a first number threshold, or the cumulative number of beam failure instances corresponding to the at least one secondary cell is greater than or equal to the first number threshold.

13 . A terminal device, comprising one or more processors, memory storing a plurality of programs that, when executed by the one or more processors, cause the terminal device to:
cancel or suspend an operation of Beam Failure Recovery (BFR) corresponding to a first secondary cell in response to deactivation of the first secondary cell.

14 . The terminal device according to claim 13 , wherein when the plurality of programs are executed by the one or more processors, the terminal device is caused to:
deactivate the first secondary cell according to deactivation signaling from a network device or a deactivation timer for the first secondary cell.

15 . The terminal device according to claim 13 , wherein when the plurality of programs are executed by the one or more processors, the terminal device is caused to:
at a physical layer, stop measuring a beam failure detection reference signal resource corresponding to the first secondary cell.

16 . The terminal device according to claim 15 , wherein when the plurality of programs are executed by the one or more processors, the terminal device is caused to:
at a Media Access Control (MAC) layer, notify the physical layer to stop measuring the beam failure detection reference signal resource.

17 . The terminal device according to claim 13 , wherein when the plurality of programs are executed by the one or more processors, the terminal device is caused to:
at a physical layer, stop reporting a measurement status of a beam failure detection reference signal resource corresponding to the first secondary cell to a Media Access Control (MAC) layer; and/or at the MAC layer, stop receiving the measurement status of the beam failure detection reference signal resource corresponding to the first secondary cell reported by the physical layer.

18 . The terminal device according to claim 17 , wherein when the plurality of programs are executed by the one or more processors, the terminal device is caused to:
suspend or reset counting of beam failure instances corresponding to the first secondary cell.

19 . The terminal device according to claim 18 , wherein resetting the counting of the beam failure instances comprises: setting a count value of the beam failure instances to zero.

20 . The terminal device according to claim 13 , wherein when the plurality of programs are executed by the one or more processors, the terminal device is caused to:
stop monitoring of a response of the network device for the first information reported by the terminal device.
