Abstract

A beam failure processing method includes determining a beam failure of a first cell. A beam failure recovery procedure of a primary cell in the first cell and a second cell is performed before beam failure recovery of the first cell succeeds and if a beam failure of the second cell is determined. The first cell is the primary cell and the second cell is a secondary cell, or the first cell is the secondary cell and the second cell is the primary cell. The method also includes sending information to a network device. The information is used to indicate at least a beam failure of the primary cell in the first cell and the second cell.

determining a beam failure of a first cell, wherein a beam failure recovery procedure of a primary cell in the first cell and a second cell is performed before beam failure recovery of the first cell succeeds and if a beam failure of the second cell is determined, and wherein the first cell is the primary cell and the second cell is a secondary cell, or the first cell is the secondary cell and the second cell is the primary cell; and sending information to a network device, wherein the information is used to indicate at least a beam failure of the primary cell in the first cell and the second cell.

2 . The method according to claim 1 , wherein the method comprises suspending or terminating a beam failure recovery procedure of the secondary cell in the first cell and the second cell.

3 . The method according to claim 2 , wherein the suspending or terminating the beam failure recovery procedure of the secondary cell in the first cell and the second cell comprises one or more of the following:
suspending or terminating a beam failure detection timer of the secondary cell, and resetting the timer; suspending or terminating a beam failure detection counter of the secondary cell, and resetting the counter; and skipping sending beam failure recovery request information of the secondary cell to the network device.

4 . The method according to claim 1 , wherein the information sent to the network device used to indicate at least the beam failure of the primary cell in the first cell and the second cell is third information, and the method further comprises:
after determining that beam failure recovery of the primary cell in the first cell and the second cell succeeds, sending first information to the network device, wherein the first information is used to indicate a beam failure of the secondary cell in the first cell and the second cell; and receiving second information from the network device, wherein the second information is used to indicate a first beam, and the first beam is used to receive, in the secondary cell, downlink information from the network device.

5 . The method according to claim 4 , wherein the secondary cell in the first cell and the second cell is a first secondary cell, and the receiving of the second information from the network device comprises:
receiving, in the primary cell, the second information from the network device; or receiving, in a third cell, the second information from the network device, wherein the third cell is a second secondary cell in which no beam failure occurs.

6 . The method according to claim 4 , wherein the first information is sent by using a first resource, and the method further comprises:
determining that the first beam is a new available beam in the secondary cell, wherein the first beam is associated with the first resource.

7 . A beam failure processing apparatus, comprising:
at least one processor; and one or more memories coupled to the at least one processor, the one or more memories having programming instructions stored thereon that, when executed by the at least one processor, cause the apparatus to: determine a beam failure of a first cell, wherein a beam failure recovery procedure of a primary cell in the first cell and a second cell is performed before beam failure recovery of the first cell succeeds and if a beam failure of the second cell is determined, and wherein the first cell is the primary cell and the second cell is a secondary cell, or the first cell is the secondary cell and the second cell is the primary cell; and send information to a network device, wherein the information is used to indicate at least a beam failure of the primary cell in the first cell and the second cell.

8 . The apparatus according to claim 7 , wherein the apparatus is further caused to:

receiving, in the primary cell, the second information from the network device; or receiving, in a third cell, the second information from the network device, wherein the third cell is a second secondary cell in which no beam failure occurs.

12 . The apparatus according to claim 10 , wherein the first information is sent by using a first resource, and the apparatus is further caused to:
determine that the first beam is a new available beam in the secondary cell, wherein the first beam is associated with the first resource.

13 . A non-transitory computer-readable storage medium having instructions stored thereon that, when executed by a processor, causes an apparatus to:
determine a beam failure of a first cell, wherein a beam failure recovery procedure of a primary cell in the first cell and a second cell is performed before beam failure recovery of the first cell succeeds and if a beam failure of the second cell is determined, and wherein the first cell is the primary cell and the second cell is a secondary cell, or the first cell is the secondary cell and the second cell is the primary cell; and send information to a network device, wherein the information is used to indicate at least a beam failure of the primary cell in the first cell and the second cell.
