US 10,764,811 B2 · Method for handover to relay node, related device, and system

Abstract

A method for handover to a relay node, a related device, and a system, where the method includes sending, by a base station of a target cell in an initial random access procedure initiated by a terminal device for the target cell, indication information to the terminal device using a random access message to instruct the terminal device to report information about a candidate relay device corresponding to the terminal device, receiving the information about the candidate relay device from the terminal device determining, in the candidate relay device according to the information about the candidate relay device, a target relay node used for relay communication between the terminal device and the base station, and handing over the terminal device to the target relay node.

Dependent claims

A network device, comprising:

a transmitter;
a receiver;
and
a processor coupled to the transmitter and the receiver and configured to:
send, using the transmitter in an initial random access procedure initiated by a terminal device for a target cell, indication information to the terminal device using a first random access message to instruct the terminal device to report information about a candidate relay device corresponding to the terminal device;
receive, using the receiver, the information about the candidate relay device from the terminal device;
determine, in the candidate relay device according to the information about the candidate relay device, a target relay node used for relay communication between the terminal device and the network device;
and
hand over the terminal device to the target relay node.

A terminal device, comprising:

a transmitter;
a receiver;
and
a processor coupled to the transmitter and the receiver and configured to:
receive, using the receiver in an initial random access procedure for a target cell, indication information from a base station corresponding to the target cell using a first random access message, wherein the indication information instructs the terminal device to report information about a candidate relay device corresponding to the terminal device;
and
send, using the transmitter, the information about the candidate relay device to the base station in response to the indication information to enable the base station to determine a target relay node in the candidate relay device and to hand over the terminal device to the target relay node.
