As shown in fig. 1, one embodiment of the present invention provides a method 100 of side link relay processing, which may be performed by a user equipment, in other words, by software or hardware installed at the user equipment, for example, by a relay user equipment, the method comprising the steps of:

The relay capability parameters of the relay user equipment include at least one of a supported maximum rate, an average rate, a data packet delay budget PDB, a data packet error rate PER, an average time window AW, a priority level PL and a data maximum burst quantity MDBV.
S104: and carrying out relay processing according to the relay capability parameters.
Thus, in the embodiment of the present invention, the relay capability parameter of the relay user equipment is determined by the relay user equipment, where the relay capability parameter of the relay user equipment includes at least one of a supported maximum rate, an average rate, a data packet delay budget PDB, a data packet error rate PER, an average time window AW, a priority PL, and a data maximum burst MDBV, and relay processing is performed according to the relay capability parameter, so that relay processing can be reasonably implemented based on the relay capability of the relay user equipment.
As shown in fig. 2, one embodiment of the present invention provides a method 200 of side link relay processing, which may be performed by a user equipment, in other words, by software or hardware installed at the user equipment, for example, by a remote user equipment, the method comprising the steps of:

Therefore, in the embodiment of the invention, the remote user equipment performs the relay processing according to the relay capability parameter, so that the relay processing can be reasonably realized based on the relay capability of the relay user equipment.
As shown in fig. 3, one embodiment of the present invention provides a method 300 of side link relay processing, which may be performed by a user equipment, in other words, by software or hardware installed at the user equipment, for example, by a relay terminal and/or a remote user equipment, the method comprising the steps of:
s312: and the relay user equipment determines the relay capability parameters of the relay user equipment.
Wherein the relay capability parameters of the relay user equipment include at least one of a supported maximum rate, an average rate, a data packet delay budget PDB, a data packet error rate PER, an average time window AW, a priority PL and a data maximum burst quantity MDBV;
s314: and the relay user equipment sends the relay capability parameters of the relay user equipment.
The relay user equipment sends the relay capability parameters of the relay user equipment to the remote user equipment through unicast, multicast or broadcast.
In one possible implementation, the relay capability parameter of the relay user equipment may be identified by a resource from which the signal is transmitted. Specifically, the relay UE may identify the relay capability parameters of the relay UE by sending discovery on different resources, thereby distinguishing between different relay capabilities of different relay user equipments.
For example, different UE capabilities may be distinguished according to different time-frequency resources, specifically, the base station processes the discovery signal sent by the UE with the relay capability parameter of 100M rate on F1, and sends the discovery signal by the UE with the relay capability parameter of 200M rate on F2. Thus, the relay capability parameter of the relay user equipment can be identified by the resource of the transmission signal.

In case the remote user equipment decides to establish a relay connection, a first connection request is sent to the relay user equipment.
S316: the relay user equipment receives the first connection request to establish a relay connection.
An embodiment of the present invention herein shows a specific implementation of the foregoing step S312. Of course, it should be understood that step S312 may be implemented in other manners, and embodiments of the present invention are not limited thereto.
In one possible implementation, step S312 may include: and determining the relay capacity parameter of the relay user equipment according to the signal condition of the radio interface Uu port between the universal terrestrial radio access network UTRAN and the relay user equipment, which is measured by the relay user equipment.
For example, when the base station processes that the downlink Reference Signal Received Power (RSRP) of the relay UE for the camping cell is 20dbm, the relay UE may determine that its own relay capability parameter includes that the supported maximum rate is 10M rate. When the downlink RSRP of the relay UE for the camping cell is 40dbm, the relay UE may determine that the relay capability parameter includes a supported maximum rate of 20M.
In one possible implementation, step S312 may include: and determining the relay capability parameter of the relay user equipment according to the characteristics of the service cell connected with the relay user equipment.
For example, when a relay UE connects to a cell with a subcarrier spacing of 30khz, the relay UE may determine that its own relay capability parameters include a packet delay budget PDB, may claim to support a 10ms delay. When the relay UE connects to a cell with a subcarrier spacing of 120khz, the relay UE may determine its own relay capability parameters including a packet delay budget PDB, and may claim its own relay function supporting a 5ms delay.
In one possible implementation, step S312 may include: and determining the relay capability parameter of the relay user equipment according to the residual resources after the relay user equipment provides service for the current remote user equipment.
Specifically, the relay UE may determine a total relay capability parameter, subtract the resource for providing service to the current remote user equipment from the total relay capability parameter, and obtain the remaining resource after providing service to the current remote user equipment, thereby determining the relay capability parameter of the relay user equipment.
For example, a relay UE may provide 100M relay capability altogether, currently serving two remote UEs, providing one UE with 50M rate and the other with 30M rate, so the relay UE may determine its own relay capability parameter as 20M rate.
Therefore, the method for processing the side link relay provided by the embodiment of the invention can reasonably declare the relay capability parameter of the relay UE by sending the relay capability parameter of the relay UE by the relay UE, and reasonably realize relay connection based on the relay capability of the relay UE.
As shown in fig. 4, another embodiment of the present invention provides a method 400 of side link relay processing, which may be performed by a user equipment, in other words, by software or hardware installed at the user equipment, for example, by a relay terminal and/or a remote user equipment, the method comprising the steps of:
s412: and the relay user equipment determines the relay capability parameters of the relay user equipment.
The relay capability parameters of the relay user equipment include at least one of a supported maximum rate, an average rate, a data packet delay budget PDB, a data packet error rate PER, an average time window AW, a priority level PL and a data maximum burst quantity MDBV.
S424: the remote user equipment sends a second connection request.
The second connection request includes a target relay capability parameter of the remote user equipment.
S414: the relay user equipment receives the second connection request.
The second connection request includes a target relay capability parameter of the remote user equipment.
S416: and the relay user equipment sends a connection notification to the remote user equipment so as to establish a relay connection.
In one possible implementation, the relay user equipment may compare the target relay capability parameter of the remote user equipment with the relay capability parameter determined in step S412, and in case the relay capability parameter determined in step S412 satisfies the target relay capability parameter of the remote user equipment, send a connection notification to the remote user equipment, thereby establishing the relay connection.
Otherwise, in the case that the relay capability parameter determined in step S412 does not meet the target relay capability parameter of the remote user equipment, the relay user equipment may not respond to the second connection request, not establish the relay connection with the remote user equipment, and may also send a notification to the remote user equipment indicating that the relay connection cannot be established.
S426: and the remote user equipment receives the connection notification sent by the relay user equipment, so that relay connection is established.
In one possible implementation, step S412 may include: and determining the relay capacity parameter of the relay user equipment according to the signal condition of the radio interface Uu port between the universal terrestrial radio access network UTRAN and the relay user equipment, which is measured by the relay user equipment.
In one possible implementation, step S412 may include: and determining the relay capability parameter of the relay user equipment according to the characteristics of the service cell connected with the relay user equipment.
In one possible implementation, step S412 may include: and determining the relay capability parameter of the relay user equipment according to the residual resources after the relay user equipment provides service for the current remote user equipment.
Therefore, the method for processing the side link relay provided by the embodiment of the invention can reasonably declare the relay capability parameter of the relay UE by receiving the target relay capability parameter of the remote user equipment and reasonably realize relay connection based on the relay capability of the relay user equipment.

The remote user equipment determines whether to establish the relay connection according to the relay capability parameter of the relay user equipment. Specifically, if the relay capability parameter of the relay user equipment received by the remote user equipment meets the target value of the relay capability parameter of the remote user equipment, the relay connection is determined to be established.
S528: the remote user equipment sends a first connection request to establish the relay connection.
S518: the relay user equipment receives the first connection request to establish the relay connection.
