Abstract
Provided are a path switching method and apparatus, a path switching configuration method and apparatus, a communication node and a non-transitory computer-readable storage medium. The path switching method is applied to a first user equipment (UE) and may include receiving path switching configuration information, and switching a communication link with a target node from a first link to a second link according to the path switching configuration information.
Claims12
A path switching method, applied to a first user equipment (UE), comprising:
- receiving serving cell information of a relay;
- sending, to a base station, a message including relay-associated information comprising a relay identifier, the serving cell information of the relay, and measurement information of the relay, the measurement information comprising a PC5 reference signal received power (RSRP);
- receiving path switching configuration information from the base station, wherein the path switching configuration information comprises path switching criteria and switching instruction information, the path switching criteria comprising at least one of a first threshold of link quality of a first link and a threshold of PC5 interface link quality of a second link, the switching instruction information comprising the relay identifier;
- and
- switching a communication link with the base station from the first link to the second link in response to the path switching criteria being met, wherein the first link is for direct communication with the base station and the second link is for communication with the base station through the relay, wherein the path switching criteria being met comprises at least one of the link quality of the first link being lower than the first threshold of the link quality or the PC5 interface link quality of the second link being higher than the threshold of the PC5 interface link quality of the second link.

A first user equipment (UE), comprising:
- at least one processor configured to:
- receive, via a receiver, serving cell information of a relay;
- send, via a transmitter to a base station, a message including relay-associated information comprising a relay identifier, the serving cell information of the relay, and measurement information of the relay, the measurement information comprising a PC5 reference signal received power (RSRP);
- receive, via the receiver, path switching configuration information from the base station, wherein the path switching configuration information comprises path switching criteria and switching instruction information, the path switching criteria comprising at least one of a first threshold of link quality of a first link and a threshold of PC5 interface link quality of a second link, the switching instruction information comprising the relay identifier;
- and
- switch a communication link with the base station from the first link to the second link in response to the path switching criteria being met, wherein the first link is for direct communication with the base station and the second link is for communication with the base station through the relay, wherein the path switching criteria being met comprises at least one of the link quality of the first link being lower than the first threshold of the link quality or the PC5 interface link quality of the second link being higher than the threshold of the PC5 interface link quality of the second link.
