The embodiment of the present application can be applied to a sidelink relay architecture, as shown in fig. 2 and 3, and fig. 2 and 3 show two typical sidelink relay architecture diagrams.

Under the sidelink relay architecture shown in fig. 2, the relay terminal plays a role of data relay, and may forward data and signaling from the remote terminal to the network device, and may also forward data and signaling from the network device to the remote terminal. Fig. 2 is only a simple example of the relay architecture, and actually, the number of relay terminals between the remote terminal and the network device may also be multiple.

Fig. 3 is only a simple example of the relay architecture, and actually, the number of relay terminals between the remote terminals may also be multiple.

It should be noted that, a relay terminal (relay UE) mentioned in the embodiments of the present specification generally refers to a UE that is a relay for a remote terminal to communicate with other UEs/network devices, and therefore, other technical terms may also be used to describe a relay terminal, such as a relay, a relay node, and so on. A remote terminal (remote UE) in various embodiments of the present specification generally refers to a UE that needs to communicate with other UEs/network devices through a relay, and therefore, other technical terms may also be used to describe a remote terminal, such as a remote terminal, and the like.

The relay UE mentioned in the embodiments of the present application may refer to a UE-to-network relay shown in fig. 2, or may be extended to a UE-to-UE relay shown in fig. 3. The former means that one end of relay UE is connected with remote UE and the other end is connected with network equipment, and the latter means that both ends of relay UE are connected with remote UE.

In addition, the names of relay UE and remote UE mentioned in the embodiments of the present application may be replaced with other terms. In principle, remote UE refers to UE that needs to communicate with other UE/network device sides through relays; relay UE refers to a UE that is a relay for remote UE to communicate with other UEs/base stations.

The execution main body of the embodiment of the present application may be a remote terminal in a sidelink relay architecture, or may be a relay terminal.

In one embodiment, in a case where the execution subject is a relay terminal, the first message and the second message are messages transmitted by the relay terminal, and the first message and the second message may include one of the following examples one to five:

example one: the first message is transmitted by the relay terminal through an UpLink (UpLink, UL), and the first message is a message of the relay terminal itself; the second message is transmitted by the relay terminal through a Sidelink (SL), and the second message is relayed by the relay terminal as a remote terminal.

It should be noted that, the "own" message of the relay terminal mentioned in the embodiments of the present specification may include service data related to the relay terminal itself, where the service data is triggered by a higher layer of the relay terminal; some signaling for controlling the behavior of the relay terminal itself may also be included.

Example two: the first message is transmitted by the relay terminal through UL, and the first message is transferred by the relay terminal as a remote terminal; the second message is transmitted by the relay terminal through SL, and the second message is a message of the relay terminal itself.

Example three: the first message is transmitted by the relay terminal through the UL, and the first message is a message relayed by the relay terminal as a remote terminal (e.g., remote UE 1); the second message is transmitted by the relay terminal through SL, and the second message is relayed by the relay terminal as a remote terminal (e.g. remote UE 2).

Example four: the first message is transmitted by the relay terminal through UL, and the first message is the message of the relay terminal; the second message is transmitted by the relay terminal through the UL, and the second message is relayed by the relay terminal for the remote terminal.

Example five: the first message is transmitted by the relay terminal through the SL, and the first message is the message of the relay terminal; the second message is transmitted by the relay terminal through the SL, and the second message is relayed by the relay terminal as a remote terminal.

In another embodiment, in a case where the execution subject is a remote terminal, the first message and the second message are messages transmitted by the remote terminal, and the first message and the second message include one of the following example six and example seven:

example six: the first message is transmitted by the remote terminal through SL, and the first message does not need to be transferred by the relay terminal; the second message is transmitted from the remote terminal to the relay terminal through the SL, and the second message needs to be relayed by the relay terminal.

Example seven: the first message is transmitted by the remote terminal through UL, and the first message is the message of the remote terminal; the second message is transmitted from the remote terminal to the relay terminal through the SL, and the second message needs to be relayed by the relay terminal.

It should be noted that, the message of the remote terminal "itself" mentioned in the embodiments of the present specification may include service data related to the remote terminal itself, where the service data is triggered by a higher layer of the remote terminal; some signaling for controlling the behavior of the remote terminal itself may also be included.

To describe the method for determining the priority in the embodiment 100 in detail, the method for determining the priority of the first message and the method for determining the priority of the second message will be described in detail below with reference to the seven examples.

It should be noted that, in order to avoid confusion, the same priority parameters x and y are used and the same first offset (offset) is used in the following embodiments of the present specification for explanation. It is understood that the values of these parameters may be different in different embodiments, for example, in one embodiment, the first offset amount (offset) is 5, in another embodiment, the first offset amount (offset) is 6, and so on.

The first threshold a, the third threshold C, the fifth threshold E and the seventh threshold G mentioned in the following embodiments of the present specification are configured or agreed by the network side or configured by other UEs, generally for priority comparison of related data or signaling for transmission on UL. In practice, the first threshold a, the third threshold C, the fifth threshold E and the seventh threshold G may be equal.

The second threshold B, the fourth threshold D, the sixth threshold F and the eighth threshold H mentioned in the following embodiments of the present specification are configured or agreed by the network side or configured by other UEs, and are generally used for priority comparison of related data or signaling transmitted on the SL. In practice, the second threshold B, the fourth threshold D, the sixth threshold F and the eighth threshold H may be equal.

For the information related to the transition on UL or SL, there are three cases: 1) special thresholds, such as a first threshold a, a second threshold B, etc., may be set; 2) or, no special threshold may be set, such as directly using the threshold used for transmitting non-relay messages; 3) the threshold + offset may also be used as a new threshold, e.g., a third threshold + offset.

With respect to the above example one, example two, example three, example four, and example seven, determining the priority of the first message and the second message mentioned in embodiment 100 includes: comparing the priority parameter x of the first message with a first threshold a, and comparing the priority parameter y of the second message with a second threshold B; and determining the priority of the first message and the second message according to the comparison result.

Thus, the transmitting of the first message and the second message according to the determined priority in embodiment 100 may include: in the first case, the priority of the first message is higher (or called higher) than that of the second message, and the first message is transmitted preferentially; in a second case, the priority of the second message is greater than the priority of the first message, the second message being transmitted preferentially.

Wherein the second case comprises the priority parameter of the second message being less than the second threshold and the priority parameter of the first message being greater than the first threshold, i.e. y A; the first case is other than the second case. For example, the first case includes: y B and x > A; y > B and x < A.

It should be noted that, in the embodiments of the present specification, a priority parameter, such as the priority parameter x, is default to be lower, and the priority is higher. Reference to y < B in this embodiment is to be understood as having a priority above the threshold B, but when the parameter value is less than B. The subsequent embodiments are similar thereto.

It should be noted that the first case and the second case do not describe the case where the priority is equal, and in fact, the embodiment can flexibly generalize the case of "equal" to the first case or the second case, for example, the second case can also be y ≦ B and x > a, y ≦ B and x ≧ a, or y < B and x ≧ a, and accordingly, the first case can also have various implementations in consideration of the case of "equal".

For the seven examples from the first example to the seventh example, the determining the priority of the first message and the second message in the embodiment 100 includes: comparing the priority parameter x of the first message with the priority parameter y of the second message; and determining the priority of the first message and the second message according to the comparison result.

Thus, the transmitting the first message and the second message according to the determined priority in embodiment 100 includes: preferentially transmitting the first message when the priority parameter (which refers to a priority value, the lower the value, the higher the priority) of the first message is less than or equal to the priority parameter of the second message, i.e. x is less than or equal to y; and in the case that the priority parameter of the first message is larger than the priority parameter of the second message, namely x is larger than y, the second message is transmitted preferentially.

Optionally, the transmitting the first message and the second message according to the determined priority in embodiment 100 may further include: in the case that x < y, transmitting the first message preferentially; and preferentially transmitting the second message under the condition that x is larger than or equal to y.

For the three examples of the first example, the third example, and the seventh example, determining the priority of the first message and the second message in embodiment 100 includes: comparing the priority parameter x of the first message with a third threshold C and the priority parameter y of the second message with the sum of a fourth threshold D and a first offset; and determining the priority of the first message and the second message according to the comparison result.

Thus, the transmitting the first message and the second message according to the determined priority in embodiment 100 includes:

in the first case, the first message is preferentially sent;

in a second case, preferentially sending the second message;

wherein the second case comprises the priority parameter of the second message being less than the sum of the fourth threshold and a first offset, and the priority parameter of the first message being greater than the third threshold, y < D + offset and x > C; the first case is other than the second case. For example, the first case includes: y < D + offset and x < C; y > D + offset and x > C; y > D + offset and x < C.

It should be noted that the first case does not describe the case of equal priority, and in fact, the embodiment can flexibly generalize the case of "equal" to the first case or the second case, for example, the second case can also be y ≦ D + offset and x > C, y ≦ D + offset and x ≧ C, and y < D + offset and x ≧ C, and accordingly, the first case can also have various implementations in consideration of the case of "equal".

The above-mentioned first offset amount offset may be determined by at least one of the following factors:

1) the priority of the second message itself relayed for the remote terminal, for example, the priority of the service data or signaling itself relayed for the remote UE.

2) A Quality of Service (QoS) budget for the remote terminal when relaying the second message, for example, a QoS budget for the remote UE when relaying the traffic data.

The QoS budget mentioned in this example can be guaranteed for each hop, for example, when the overall QoS latency is 10ms, and when the first message takes 6ms from the remote terminal to the relay terminal, the QoS budget in transit is 4 ms. Or, the overall delay and the delay of each part are defined from the beginning, then the delay from the relay terminal to the network device side is defined to be 5ms, and then the QoS budget when relaying the first message is 5 ms. This example illustrates that the first offset is 1 when the QoS budget is within a first span, 2 when the QoS budget is within a second span, and so on.

3) The hop count of the second message relayed for the remote terminal, for example, the hop count of the service data or signaling relayed for the remote UE.

The hop count mentioned in this example is, for example, a certain message reaches the current relay terminal after passing through two relay terminals from the remote terminal, and the hop count may be 2 or 3 (specifically, calculated depending on the number of relay terminals that have been relayed or calculated by the number of transmission paths); for another example, a certain message reaches the current relay terminal after passing 3 relay terminals from the far end, and the hop count is 3 or 4. For example, when the hop count is 2, the first offset amount is 6; the first offset is 4 for a hop count of 3, and so on.

4) First indication information, where the first indication information indicates that the second message relayed by the remote terminal is a Relay message, for example, an indication that the second message is a Relay message.

5) Identification of the remote terminal.

6) An identity of the relay terminal.

For example, if the current hop count is 1, then the offset is M, the current hop count is 2, and the offset is N. For another example, the second threshold B is originally used for comparing the traffic data or signaling of the Relay UE that needs to be sent over the SL with the second threshold B, and when the message indicates that the message is the traffic data or signaling that needs to be relayed for the remote UE, the message is compared with the threshold B + offset. For another example, when the remote UE id is a, the offset is M1, and when the remote UE id is B, the offset is N1; for another example, when the remote UE id is a, the offset is M2, and when the remote UE id is not a, the offset is 0.

It should be noted that the aforementioned first offset may be determined by at least one of the following factors, which may represent that the first offset is equal to any one of the factors 1) to 6), or may represent that the first offset has a certain mapping relationship with any one of the factors 1) to 6), and the mapping relationship is obtained by the certain mapping relationship through the certain mapping relationship, where the mapping relationship may be implemented by a protocol agreement, network device configuration, peer UE configuration, or UE.

When a plurality of factors 1) to 6) are generated together, one offset may be generated based on comprehensive consideration, and different factors may correspond to different offsets. Such as: when the remote UE id is a and the hop count is 1, the priority y of the second message (e.g., the traffic data or signaling relayed for the remote UE) is compared with the threshold B + offset1+ offset 2; when the remote UE is identified as B and the number of hops is 3, the priority y of the second message (e.g., traffic data or signaling relayed for the remote UE) is compared with the threshold B + offset3+ offset4, and so on.

It should be noted that the first offset amount offset mentioned in the embodiments of the present specification may have a positive value or a negative value.

With respect to example one, example three, example four, example five, example six, and example seven above, determining the priority of the first message and the second message as set forth in embodiment 100 comprises: comparing the priority parameter x of the first message with the sum of the priority parameter y of the second message and a first offset; and determining the priority of the first message and the second message according to the comparison result.

Thus, the transmitting the first message and the second message according to the determined priority in embodiment 100 includes: preferentially sending the first message if the priority parameter of the first message is less than or equal to the sum of the priority parameter of the second message and the first offset, i.e., x < ═ y + offset; in case the priority parameter of the first message is greater than the sum of the priority parameter of the second message and the first offset, i.e. x > y + offset, the second message is sent with priority.

Optionally, the transmitting the first message and the second message according to the determined priority in embodiment 100 may further include: in the case of x < y + offset, transmitting the first message preferentially; and preferentially transmitting the second message under the condition that x is more than or equal to y + offset.

For a detailed description of the first offset amount offset, reference may be made to the foregoing embodiments.

For the second example, the determining the priority of the first message and the second message in the embodiment 100 includes: comparing the priority parameter x of the first message with the sum of a fifth threshold E and a first offset, and comparing the priority parameter y of the second message with a sixth threshold F; and determining the priority of the first message and the second message according to the comparison result.

in the first case, the first message is preferentially sent;

in a second case, preferentially sending the second message;

wherein the second case comprises the priority parameter of the second message being less than the sixth threshold and the priority parameter of the first message being greater than the sum of the fifth threshold and a first offset, y < F and x > E + offset; the first case is other than the second case. For example, the first case includes: y < F and x < E + offset; y > F and x > E + offset; y > F and x < E + offset.

It should be noted that the first case does not describe the case of equal priority, and in fact, the embodiment can flexibly generalize the case of "equal" to the first case or the second case, for example, the second case can also be y ≦ F and x > E + offset, y ≦ F and x ≧ E + offset, and y < F and x ≧ E + offset, and accordingly, the first case can also have various implementations in consideration of the case of "equal".

For the second example, the determining the priority of the first message and the second message in the embodiment 100 includes: comparing the priority parameter x of the first message with the offset of the first offset and with the priority parameter y of the second message; and determining the priority of the first message and the second message according to the comparison result.

Thus, the transmitting the first message and the second message according to the determined priority in embodiment 100 includes: preferentially sending the first message if the sum of the priority parameter of the first message and the first offset is less than or equal to the priority parameter of the second message, i.e. x + offset < y; in case the sum of the priority parameter of the first message and the first offset is larger than the priority parameter of the second message, i.e. x + offset > y, the second message is sent preferentially.

Optionally, the transmitting the first message and the second message according to the determined priority in embodiment 100 may further include: in the case of x + offset < y, transmitting the first message preferentially; and preferentially transmitting the second message when x + offset is larger than or equal to y.

For the fourth example, the determining the priority of the first message and the second message in the embodiment 100 includes: comparing the priority parameter x of the first message with a seventh threshold G and comparing the sum of the priority parameter y and the first offset of the second message with an eighth threshold H; and determining the priority of the first message and the second message according to the comparison result.

in the first case, the first message is preferentially sent;

in a second case, preferentially sending the second message;

wherein the second case comprises the sum of the priority parameter and the first offset of the second message being less than the eighth threshold and the priority parameter of the first message being greater than the seventh threshold, y + offset < H and x > G; the first case is other than the second case. For example, the first case includes: y + offset < H and x < G; y + offset > H and x > G + offset; y + offset > H and x < G.

It should be noted that the first case does not describe the case of equal priority, and in fact, the embodiment can flexibly generalize the case of "equal" to the first case or the second case, for example, the second case can also be y + offset ≦ H and x > G, the second case can also be y + offset ≦ H and x ≧ G, and the second case can also be y + offset < H and x ≧ G, and accordingly, the first case can also have various implementations in consideration of the case of "equal".

To describe the priority determination method provided in the embodiments of the present application in detail, the following description will be made with reference to several specific embodiments.

The first embodiment of the invention:

when the Relay UE needs to send its own service data or signaling to the network device side on the UL (i.e. the first message mentioned above), and send the service data or signaling for relaying the remote UE to the remote UE or to other UEs (UE-to-UE Relay) on the SL (i.e. the second message mentioned above). The priority of the first message and the second message may be determined by one of the following methods 1 to 4.

The embodiment assumes: the service data or signaling of the Relay UE needing to be sent on the UL is x; the priority of service data or signaling which needs to be sent by Relay UE on SL is y; the priority comparison threshold for related data or signaling transmitted on the UL is a; the priority comparison threshold for the relevant data or signaling transmitted on SL is B.

The method comprises the following steps:

comparing the priority x of the own service data or signaling which needs to be sent on the UL by the Relay UE with the threshold A, and simultaneously comparing the priority y of the service data or signaling transferred for the remote UE with the threshold B. If y is less than B and x is greater than A, the business data or signaling transferred for the remote UE is preferentially transmitted; otherwise, the service data or signaling of the Relay UE is preferentially transmitted. For the detailed meaning of "otherwise", reference may be made to the detailed descriptions of "first case" and "second case" in the previous embodiments, which are similar to the subsequent embodiments.

The method 2 comprises the following steps:

directly comparing the priority x of the service data or signaling of the Relay UE which needs to be sent on the UL with the priority y of the service data or signaling transferred for the remote UE, and preferentially transmitting the service data or signaling of the Relay UE if x < > is y; otherwise, the service data or signaling transferred for the remote UE is preferentially transmitted.

The method 3 comprises the following steps:

comparing the priority x of the own service data or signaling which the Relay UE needs to send on the UL with a threshold A, and simultaneously comparing the priority y of the service data or signaling transferred for the Relay UE with a threshold B + offset. If y A, preferentially transmitting service data or signaling transferred for the Remote UE; otherwise, the service data or signaling of the Relay UE is preferentially transmitted.
