Abstract
This application provides a link failure recovery method and apparatus. When a link failure occurs and link recovery is performed, if a terminal device determines that no new link is identified, according to the method, the terminal device may report, to a network device, an identifier of a cell in which the link failure occurs and information indicating whether a new link is identified for each cell. The network device may reconfigure a new resource set based on the information, and notify the terminal device of the new resource set by using downlink control information DCI. In other words, a reference signal in another resource set is triggered by using the DCI, and the reference signal in the resource set is reported for link recovery.
Claims20
A link failure recovery method, comprising:
- determining that a link failure occurs in L first cells;
- and
- sending a first request message comprising first indication information to indicate cell information of the L first cells, L≥1, and L is an integer, wherein
- the first indication information comprises at least one of a first part of content or a second part of content, wherein the first part of content is to indicate cell identifiers of the L first cells, and wherein the second part of content is to indicate whether there is no first reference signal that satisfies a first preset condition.
A link failure recovery method, comprising:
- receiving a first request message comprising first indication information to indicate cell information of L first cells in which a link failure occurs, L≥1, and L is an integer, wherein the first indication information comprises at least one of a first part of content or a second part of content, wherein the first part of content is to indicate cell identifiers of the L first cells, and wherein the second part of content is to indicate whether there is no first reference signal that satisfies a first preset condition;
- and
- determining the cell information of the L first cells based on the first request message.
A link failure recovery apparatus, comprising:
- a processor, configured to determine that a link failure occurs in L first cells;
- and
- a transceiver, configured to send a first request message comprising first indication information to indicate cell information of the L first cells, L≥1, and L is an integer, wherein
- the first indication information comprises at least one of a first part of content or a second part of content, wherein the first part of content is to indicate cell identifiers of the L first cells, and wherein the second part of content is to indicate whether there is no first reference signal that satisfies a first preset condition.
A link failure recovery apparatus, comprising:
- a transceiver, configured to receive a first request message comprising first indication information to indicate cell information of L first cells, the L cells are cells in which a link failure occurs, L≥1, and L is an integer, wherein the first indication information comprises at least one of a first part of content or a second part of content, wherein the first part of content is to indicate cell identifiers of the L first cells, and wherein the second part of content is to indicate whether there is no first reference signal that satisfies a first preset condition;
- and
- a processor, configured to determine the cell information of the L first cells based on the first request message.
