Detailed Description

As described in the background art, in the prior art, when a radio link failure occurs in a communication link between a relay device and a serving base station, the relay device performs inter-base station handover, or the relay device performs cell selection/reselection, the relay device notifies a remote device served by the relay device, and further triggers the remote device to reselect the relay device or a serving cell.

However, when the relay device cannot continue to implement the relay function, the relay device does not inform the remote device that it serves, so that the remote device that it serves may not be able to access the network.

In the embodiment of the present invention, when the relay device determines that it cannot continue to implement the relay function, the relay device may send the first indication information to indicate that it cannot continue to implement the relay function. The remote device served by the relay device may receive the first indication information, so as to learn that the relay device cannot continue to implement the relay function, and further perform any operation such as cell selection/reselection, relay device selection/reselection, RRC reestablishment, and the like according to the user equipment status, and reselect a suitable cell or relay device to re-access the network.

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below.

Referring to fig. 1, a flowchart of a relay communication method in an embodiment of the present invention is given. Referring to fig. 2, a communication system architecture diagram in an embodiment of the present invention is presented. The relay communication method according to the embodiment of the present invention is described in detail below with reference to fig. 1 and 2.

The Relay communication method provided in the embodiment of the invention can be executed by a chip (such as a baseband chip) with a data processing function in a Relay device (Relay UE), and can also be executed by a chip module of the chip with the data processing function in the Relay device.

In fig. 2, a Remote device (Remote UE) communicates with a serving base station (gNB) through a Relay device (Relay UE). And forwarding control signaling and user plane data corresponding to the remote equipment through the relay equipment.

The relay device may communicate with the serving base station via a Uu link (link), and the remote device may communicate with the relay device via a PC5 link (link).

Step S101, determining that the relay function cannot be continuously implemented.

In implementations, it may be determined whether the relay device is able to continue to implement the relay function by detecting the signal quality of the Uu link between the relay device and the serving base station.

In an embodiment of the present invention, the signal quality of the Uu link of the relay device and the serving base station may be characterized by a reference signal received power (Reference Signal Receiving Power, RSRP) parameter. It will be appreciated that the signal quality of the Uu link of the relay device with the serving base station may also be characterized by other parameters, not limited to the RSRP parameters described above.

In the embodiment of the invention, the service base station can configure a Uu link signal quality minimum threshold value for the relay equipment in advance and send the Uu link signal quality minimum threshold value to the relay equipment. When the relay device detects that the signal quality corresponding to the Uu link is smaller than the minimum threshold, the relay device can determine that the signal quality corresponding to the current Uu link is poor, and the relay device may not be capable of continuing to realize the relay function.

In the embodiment of the invention, the service base station can also configure a Uu link signal quality maximum threshold value for the relay equipment in advance and send the Uu link signal quality maximum threshold value to the relay equipment. When the relay device detects that the signal quality corresponding to the Uu link is greater than the maximum threshold, the relay device can determine that the signal quality corresponding to the current Uu link is stronger, the distance between the relay device and the service base station may be closer, and the distance between the relay device and the remote device is farther. At this time, the relay apparatus may not continue to implement the relay function.

In the embodiment of the invention, the service base station can also configure a Uu link signal quality maximum threshold value and a Uu link signal quality minimum threshold value for the relay equipment at the same time and send the Uu link signal quality maximum threshold value and the Uu link signal quality minimum threshold value to the relay equipment. And when the relay equipment detects that the signal quality corresponding to the Uu link between the service base stations is between the maximum threshold value and the minimum threshold value, the relay equipment can continue to realize the relay function. Otherwise, when the relay device detects that the signal quality corresponding to the Uu link is greater than the maximum threshold value or the signal quality corresponding to the Uu link is less than the minimum threshold value, it can be determined that the relay function cannot be continuously realized at present.

Step S102, first indication information is sent.

In a specific implementation, when the relay device determines that the relay function cannot be continuously implemented, the first indication information may be sent, where the first indication information may be used to indicate that the relay device cannot continuously implement the relay function.

The relay device may send the first indication information to the remote device for service, or may send the first indication information to the access network device for service, or may send the first indication information to both the remote device for service and the access network device for service.

In the embodiment of the invention, when the relay device sends the first indication information to the remote device of the service, the first indication information can be sent to the remote device of the service through PC5-S signaling, and the first indication information can also be sent to the remote device of the service through PC5-RRC signaling.

The remote devices setting the relay device service include a remote device 1, a remote device 2, and a remote device 3. When the relay device determines that the relay function cannot be continued, the first instruction information may be transmitted to the remote device 1, the remote device 2, and the remote device 3.

In the embodiment of the invention, when the relay device sends the first indication information to the remote device serving through the PC5-S signaling, the information carried by the PC5-S signaling is the first indication information.

When the relay device sends the first indication information to the served remote device through the PC5-RRC signaling, the relay device may issue a notifiationessagesidelink message to the remote device, where the notifiationessagesidelink message is used to indicate that the relay device cannot implement the relay function.

In the embodiment of the present invention, after the relay device determines that the relay function cannot be continuously implemented, a discovery message (discovery message) may also be broadcast, where the discovery message may carry the first indication information. After receiving the discovery message, the remote device served by the relay device can acquire the first indication information from the remote device, so as to acquire that the relay device currently providing the service cannot continue to realize the relay function.

It is known in the art that when a relay device determines that it can currently implement a relay function, it broadcasts a discovery message to inform remote devices in its vicinity. In the embodiment of the invention, when the relay device determines that the relay device cannot continuously realize the relay function, the discovery message can be broadcasted so as to inform the remote device served by the relay device.

For example, the remote devices served by the relay device include the remote device 1, the remote device 2, and the remote device 3. When the relay device determines that the relay function cannot be continued currently, the discovery message is broadcast. After receiving the discovery message, the remote devices 1, 2 and 3 can determine that the relay device cannot continue to implement the relay function.

In a specific implementation, if the first indication information is sent by the relay device to the served remote device, the remote device may perform the relay communication method provided in the following embodiment.

Referring to fig. 3, another relay communication method in the embodiment of the present invention is given, and the following description is made with reference to the embodiment shown in fig. 1.

The relay communication method provided in fig. 3 may be performed by a chip (such as a baseband chip) having a data processing function in the remote device, or may be performed by a chip module of the chip including the data processing function in the remote device.

Step S301, receiving first indication information.

In an implementation, the remote device may receive the first indication information sent by the relay device. After receiving the first indication information sent by the relay device, the remote device may perform a corresponding operation according to the state of its own user equipment.

In the embodiment of the present invention, the first indication information may be used to indicate that the relay device that provides the service cannot continue to implement the relay function. Specifically, when the relay device generates the first indication information and sends the first indication information to the remote device, the description of the corresponding related content with reference to fig. 1 and fig. 1 may be correspondingly referred to, which is not repeated herein.

Step S302, corresponding operation is executed according to the state of the user equipment.

In practical applications, the ue states corresponding to the remote device may include RRC connected state, IDLE state (IDLE state), inactive state (inactive state), and so on. The remote device may be in different user device states and may perform different operations.

In the embodiment of the present invention, if the remote device is in a connected state, the remote device may execute an RRC reestablishment procedure; if the remote device is in an idle state or inactive state, the remote device may perform cell selection or cell reselection operations, or may perform relay device selection or relay device reselection operations.

For example, the remote device 1 is in an RRC connected state, and after receiving the first indication information, the remote device 1 knows that the relay device cannot continue to implement the relay function, and the remote device 1 executes an RRC reestablishment procedure.

After receiving the first indication information, the remote device 1 knows that the relay device cannot continue to realize the relay function, and the remote device 2 performs the relay device reselection operation.

The remote device 3 is in an idle state, and after receiving the first indication information, the remote device 1 knows that the relay device cannot continue to realize the relay function, and the remote device 3 performs a cell reselection operation.

In a specific implementation, the relay device that cannot continue to implement the relay function may also send the first indication information to the access network device that provides the service. For a remote device in a connected state, the relay communication method provided by the following embodiment may be performed.

Referring to fig. 4, another relay communication method according to an embodiment of the present invention is shown, and is described below in conjunction with fig. 1 and the corresponding description.

The relay communication method provided in fig. 4 may be performed by a chip (such as a baseband chip) having a data processing function in the remote device, or may be performed by a chip module of the chip including the data processing function in the remote device.

Step S401, receiving measurement configuration information sent by the serving access network device.

In a specific implementation, the relay device may carry the first indication information through RRC dedicated signaling, and send the RRC dedicated signaling to the serving access network device. After receiving the first indication information, the access network device knows that the relay device cannot continue to realize the relay function at present, and can generate measurement configuration information and send the measurement configuration information to the remote device served by the relay device. The measurement configuration information may be used in a measurement procedure of the remote device.

In embodiments of the present invention, measurement configuration information may be used to instruct the remote device which cells/relay devices to measure. Specifically, the specific content included in the measurement configuration information may refer to measurement configuration information configured in the existing handover process, which is not described herein.

In the embodiment of the invention, the access network device can issue the measurement configuration information to the relay device, and then the relay device issues the measurement configuration information to the remote device of the service.

Step S402, executing a corresponding measurement operation according to the measurement configuration information, and reporting a measurement result corresponding to the measurement operation.

In a specific implementation, after receiving the measurement configuration information, the remote device may execute a corresponding measurement operation, and report the obtained measurement result to the serving base station. The measurement operation performed by the remote device according to the measurement configuration information, the operation of reporting the measurement result, and the like may refer to the prior art.

In the embodiment of the invention, the remote device can report the measurement result to the relay device and then report the measurement result to the service base station by the relay device.

After receiving the measurement result reported by a certain remote device, the service base station can trigger a switching process, such as switching negotiation with base stations belonging to other relay devices/other cells, if the other party allows, the service base station can switch the remote device to the corresponding relay device/cell, and send a switching command to the remote device. The serving base station may send a handover command to the relay device, and the relay device forwards the handover command to the remote device.

For example, the serving base station receives the measurement result reported by the remote device 1. After determining to switch the remote device 1 to other cells, the serving base station sends a switching command to the relay device. The relay device forwards the received handover command to the terminal device 1. After receiving the handover command, the terminal device 1 performs a cell handover operation.

In the embodiment of the invention, the service base station does not receive the measurement result sent by the remote equipment. For example, the remote device does not receive measurement configuration information issued by the serving base station, or the remote device does not report the measurement result successfully.

When the serving base station does not receive the measurement result reported by a certain remote device, the serving base station can issue an RRC reestablishment command to the remote device. After receiving the RRC reestablishment command, the remote device may execute an RRC reestablishment procedure according to the RRC reestablishment command. The specific flow of the remote device performing the RRC reestablishment operation may also be referred to in the prior art, and will not be described herein.

The serving base station may first issue the RRC reestablishment command to the relay device, and then the relay device forwards the RRC reestablishment command to the corresponding remote device.

For example, the serving base station does not receive the measurement result reported by the remote device 2. The serving base station sends an RRC reestablishment command to the relay device. The relay device forwards the received RRC reestablishment command to the terminal device 2. After receiving the RRC reestablishment command, the terminal device 2 performs an RRC reestablishment operation.

In a specific implementation, referring to fig. 5, another relay communication method in an embodiment of the present invention is given. The following description is made in connection with fig. 1 and the corresponding description, fig. 4 and the corresponding description.

The relay communication method provided in fig. 5 may be executed by a chip having a data processing function in the access network device, or may be executed by a chip module of the chip including the data processing function in the access network device.

In step S501, first indication information is received.

Step S502, configuring and issuing measurement configuration information to a remote device.

In embodiments of the present invention, measurement configuration information may be used to instruct the remote device which cells/relay devices to measure. Specifically, the specific content included in the measurement configuration information may refer to measurement configuration information configured in the existing handover process, and will not be described herein.

As can be seen, in the embodiment of the present invention, when the relay device determines that it cannot continue to implement the relay function, the relay device may send the first indication information to indicate that it cannot continue to implement the relay function. The remote device served by the relay device may receive the first indication information, so as to learn that the relay device cannot continue to implement the relay function, and further perform any operation such as cell selection/reselection, relay device selection/reselection, RRC reestablishment, and the like according to the user equipment status, and reselect a suitable cell or relay device to re-access the network.
