Relay terminal device measurement reporting method, and apparatus

A method for receiving information of a relay terminal device, performed by a network device, comprising:

• sending, via a radio resource control (RRC) message, second indication information to a remote terminal device, wherein the second indication information is configured to indicate a trigger condition for sending first indication information;
• receiving the first indication information sent by the remote terminal device, wherein the first indication information is configured to indicate information of a specified relay terminal device, and the information of the specified relay terminal device is determined based on a discovery signal;
• wherein the trigger condition comprises detection of a trigger event;
• wherein the trigger event comprises:
• a reference signal receiving power (RSRP) of the discovery signal being greater than a first threshold;
• or a RSRP of a sidelink communication signal being greater than a second threshold;
• wherein the information of the specified relay terminal device comprises an identification (ID) of a relay terminal device, an ID of a serving cell of the relay terminal device and a measurement result of the relay terminal device;
• wherein the ID of the serving cell comprises:
• an ID of a cell where a relay terminal device in an idle state resides;
• or an ID of a cell where a relay terminal device in an inactive state resides.

A communication apparatus, comprising a processor, and a memory having computer programs stored thereon, wherein when the computer programs are executed by the processor, the communication apparatus is caused to perform:

• determining information of a specified relay terminal device based on a discovery signal;
• receiving, via a radio resource control (RRC) message, second indication information sent by a network device;
• determining a trigger condition based on the second indication information sent by the network device;
• determining that the trigger condition is satisfied, and sending first indication information to the network device, wherein the first indication information is configured to indicate the information of the specified relay terminal device;
• wherein the trigger condition comprises detection of a trigger event;
• wherein the trigger event comprises:
• a reference signal receiving power (RSRP) of the discovery signal being greater than a first threshold;
• or a RSRP of a sidelink communication signal being greater than a second threshold;
• wherein the information of the specified relay terminal device comprises an identification (ID) of a relay terminal device, an ID of a serving cell of the relay terminal device and a measurement result of the relay terminal device;
• wherein the ID of the serving cell comprises:
• an ID of a cell where a relay terminal device in an idle state resides;
• or an ID of a cell where a relay terminal device in an inactive state resides.
