Abstract
Embodiments of the present disclosure relate to methods and apparatuses for relay replacement. According to some embodiments of the disclosure, a method may include: receiving assistant information associated with a first network node, which functions as a relay node between the BS and a user equipment (UE); and in response to initiating a replacement procedure to replace the first network node based on the received assistant information, deactivating the first network node and activating a second network node as the relay node.
Claims21
A method performed by a base station (BS), comprising:
- receiving assistant information associated with a first network node, which functions as a relay node between the BS and a user equipment (UE);
- and
- in response to initiating a replacement procedure to replace the first network node based on the received assistant information, deactivating the first network node and activating a second network node as the relay node.
6-14. (canceled)
A base station (BS) for wireless communication, comprising:
- at least one memory;
- and
- at least one processor coupled with the at least one memory and configured to cause the BS to:
- receive assistant information associated with a first network node that functions as a relay node between the BS and a user equipment (UE);
- and
- deactivate the first network node and activate a second network node as the relay node in response to a replacement procedure initiated to replace the first network node based on the assistant information.
A network node for wireless communication, comprising:
- at least one memory;
- and
- at least one processor coupled with the at least one memory and configured to cause the network node to:
- transmit, to a base station (BS), assistant information associated with the network node that functions as a relay node between the BS and a user equipment (UE);
- receive, from the BS, a deactivation indication to deactivate the network node as the relay node;
- and
- deactivate the network node in response to the deactivation indication.
A user equipment (UE) for wireless communication, comprising:
- at least one memory;
- and
- at least one processor coupled with the at least one memory and configured to cause the UE to:
- transmit a radio resource control (RRC) setup request message to a first network node that transmits the RRC setup request message to a base station (BS);
- receive a RRC reject message from the first network node that receives the RRC reject message from the BS, the RRC reject message indicating an identifier of a second network node;
- and
- perform a random access procedure according to the identifier to initiate accessing the second network node.
