The transmission method provided by the embodiments of the present application is described in detail below with reference to the accompanying drawings by using some embodiments and application scenarios thereof.

Currently, the single carrier bandwidth and the transmission rate and throughput that can be provided by sidelink technology are limited, and cannot meet the requirements of some high-rate services. Therefore, carrier Aggregation (CA) is considered to be supported on sidelink to meet the following demand for high rate traffic. However, there is a limit to simultaneous reception (which may include measurement, in other words, simultaneous measurement) or simultaneous transmission by the UE, and both the UE itself and the control node guarantee that the actual transceiving is not limited. Specifically, the method comprises the following steps:

scene 1: limitation of multiple transmissions simultaneously or within a predetermined time range

Case1: i.e. a scenario where the transmit limit TX limit is larger than the receive limit RX limit.

In this scenario, it is assumed that the number of carriers that the UE can simultaneously support transmission is 3, and the number of simultaneously received carriers is 2. Referring to fig. 2, if the UE sends the pschs on 3 carriers respectively, it can be seen that the UE can send the pschs on 3 carriers and/or CCs at the same time, and if the feedback PSFCHs corresponding to the 3 pschs are located at the same time, it means that the UE needs to receive the PSFCHs on the 3 carriers at the same time, which exceeds the reception limit or reception capability of the UE, and needs to avoid this problem through reasonable resource selection/scheduling.

Case2: i.e. one case under TX limit = RX limit.

In this scenario, it is assumed that the number of carriers that the UE can simultaneously support transmission is 2, and the number of simultaneously received carriers is 2. Referring to fig. 3, if the UE transmits 3 pschs on 3 carriers respectively, and only 2 pschs are transmitted simultaneously, so that the transmission capability of the UE is not exceeded, but the feedback PSFCHs corresponding to the 3 pschs are located at the same time, which means that the UE needs to receive the PSFCHs on the 3 carriers simultaneously, and exceeds the reception limit or reception capability of the UE, which needs to avoid this problem through reasonable resource selection/scheduling.

Case3: i.e. a case where TX limit < RX limit.

In this scenario, it is assumed that the number of carriers that the UE can simultaneously support transmission is 2, and the number of simultaneously received carriers is 3. Referring to fig. 4, if the UE receives NACK on the PSFCH of three carriers at the same time, the UE needs to perform corresponding PSSCH retransmission on the three carriers, respectively, and if the three selected retransmission resources are overlapped in time domain, the transmission limit of the UE is exceeded, resulting in abnormal retransmission.

In general, since TX and RX may have some association relationship in some cases, one of them does not exceed the corresponding limit, but the other of the association may exceed its corresponding limit.

Scene 2: limitation due to processing time

Typically, the capabilities of the UE also include time constraints such as processing delays. If the processing delay requirement cannot be met between transmissions, the transmissions may still not be performed normally. Assuming that the number of carriers that the UE can support simultaneous transmission or within a preset range is 1, referring to fig. 5, assuming that the UE transmits the pscch on carrier or CC #1, then transmits the pscch on carrier or CC #2, and then returns to the PSFCH after carrier or CC #1 ends, although the two PSSCHs are not transmitted simultaneously, if the interval between the two PSSCHs is less than the processing time required by the UE to switch carriers, it may result in abnormal transmission.

In view of the foregoing problems, embodiments of the present application provide a transmission method, an apparatus, a device, and a medium, where a target limitation of a first UE in SL transmission is defined, so that the first UE determines the target limitation of the first UE, and may determine, based on the target limitation, a transmission mode in which the first UE transmits a target transmission object.

The first device comprises at least one of: the system comprises a first UE, a second UE, a control node and other equipment; the second UE is a UE associated with the first UE sidelink transmission.

In one example, the first, actual limit, i.e., TX limit actual = TX limit, and/or RX limit actual = RX limit, and/or total limit actual = total limit.

Further optionally, in this embodiment of the present application, a first association relationship exists between the first receiving restriction and the first sending restriction; and/or the presence of a gas in the gas,

a second association exists between the actual transmission limit and any one of:

the limit is actually received and the data is,

a first transmission limit and the actual transmission limit,

a first limit of reception is set for the first,

a first reception limit and a first transmission limit; and/or the presence of a gas in the gas,

a third relationship exists between the actual reception limit and any one of:

the actual limit of the transmission is set,

a first reception limit and an actual transmission limit,

the first transmission limit is set to a value equal to or greater than the first transmission limit,

a first reception limit and the first transmission limit;

wherein the first association is related to at least one of the following preset values:

the first transmission limits a corresponding first preset value,

a second preset value corresponding to the first transmission limit;

the second association is related to at least one of the following preset values:

the first transmission limits a corresponding first preset value,

a first preset value corresponding to the actual transmission limit,

the third correlation relates to at least one of the following preset values:

the first transmission limits a corresponding second preset value,

a second preset value corresponding to the actual transmission limit;

illustratively, the first preset value (e.g., alpha hereinafter) is less than or equal to: the associated number of bearers expected to receive (e.g., alpha0, below) is sent at least once at a time or within a time range over any or preset number P of bearers.

Illustratively, the second preset value (e.g., beta, hereinafter) is less than or equal to: the associated number of bearers expected to transmit (e.g., beta0, infra) is received at least once at a time or within a time range over any or a preset number of Q bearers.

It should be noted that the first association, the second association, and the third association may also be regarded as a predetermined rule, and thus the first device may infer other restrictions based on the known partial restrictions and the predetermined rule. For example, the first device may infer the first transmission limit based on the first reception limit and the first association.

For the first transmission limit and the actual transmission limit, the control node or the first device or the other device ensures at least one of:

1): TX limit = RX limit/alpha, and/or TX limit > = RX limit/alpha0

Wherein Alpha (i.e. the first preset value corresponding to the first transmission limit) < = Alpha0.Alpha0 is the number of bearers that are expected to receive for one or more transmissions of a certain bearer (e.g. at least one of carrier, CC, cell, BWP, resource pool, resource). For example, a psch transmission on a certain carrier may correspond to one or more PSFCH receptions on a carrier, and if alpha0 is interpreted as the number of carriers that one psch transmission corresponds to expected receptions, alpha0=1. In one possible example, alpha =1.

2): RX limit = TX limit/beta, andor, RX limit > = TX limit/beta0

Wherein Beta (i.e. the second preset value corresponding to the first transmission limit) < = Beta0.Beta0 is the number of the bearer objects which are expected to be sent and received one or more times by a certain bearer object. For example, multiple PSFCH receptions on a certain carrier may correspond to multiple PSSCH transmissions on one carrier, and if beta0 is interpreted as the number of carriers received at one time corresponding to the desired transmission, then beta0=1; for example, multiple PSFCH receptions on a certain carrier would correspond to PSSCH transmissions on Y carriers, and if beta0 is interpreted as one reception corresponding to the number of carriers expected to be transmitted, then beta0= Y. In one possible example, beta =1.

3)：TX limit actual＝RX limit actual/alpha actual，

And/or, TX limit actual > = RX limit actual/alpha actual0,

and/or TX limit actual = min (TX limit, RX limit actual/alpha actual) or max (TX limit, RX limit actual/alpha actual),

and/or TX limit actual = min (TX limit, RX limit actual/alpha actual 0) or max (TX limit, RX limit actual/alpha actual 0),

and/or, TX limit actual = RX limit/alpha actual,

and/or, TX limit actual > = RX limit/alpha actual0,

and/or TX limit actual = min (TX limit, RX limit/alpha actual) or max (TX limit, RX limit/alpha actual),

and/or, TX limit actual = min (TX limit, RX limit/alpha actual 0) or max (TX limit, RX limit/alpha actual 0).

Wherein Alpha actual (i.e. the first preset value corresponding to the actual transmission limit) <= Alpha actual0.

Alpha actual0 is the number of bearers that a certain bearer should expect to receive in one or more transmissions. For example, a psch transmission on a certain carrier may correspond to one or more PSFCH receptions on a carrier, and alpha actual0=1 if alpha actual0 is interpreted as one psch transmission corresponding to the number of carriers expected to be received. In one possible example, alpha actual =1.

4)：RX limit actual＝TX limit actual/beta actual，

And/or, RX limit actual > = TX limit actual/beta actual0,

and/or RX limit actual = min or max (RX limit, TX limit actual/beta actual),

and/or, RX limit actual = min or max (RX limit, TX limit actual/beta actual 0),

and/or, RX limit actual = TX limit/beta actual,

and/or, RX limit actual > = TX limit/beta actual0,

and/or RX limit actual = min or max (RX limit, TX limit/beta actual),

and/or RX limit actual = min or max (RX limit, TX limit/beta actual 0).

Wherein Beta actual (i.e. a second preset value corresponding to the actual transmission limit) <= Beta actual0.

Beta actual0 is the number of the bearer objects which are expected to be sent and received one or more times by a certain bearer object. For example, multiple PSFCH receptions on a certain carrier will correspond to multiple PSSCH transmissions on one carrier, and if beta actual0 is interpreted as one reception corresponding to the number of carriers expected to be transmitted, then beta actual0= 1; for example, multiple PSFCH receptions on a certain carrier may correspond to PSSCH transmissions on Y carriers, and if beta actual0 is interpreted as one reception corresponding to the number of carriers desired to be transmitted, then beta actual0= Y. In one possible example, beta actual =1.

It should be noted that the above formula does not divide completely, considering that the result should be rounded up or down.

The target limitation in the embodiments of the present application will be explained below with several examples.

Example 1: transmission of one carrier wave reception of one carrier wave.

For example, assuming that the number of simultaneously supportable carriers for transmission by the UE is 3, and the number of simultaneously received carriers is 2, that is, TX limit =3, rx limit =2, the maximum number of simultaneously transmitted carriers = min (2, 3) =2, and the maximum number of simultaneously received carriers = min (2, 3) =2 when actually performing transmission, that is, the number of simultaneously transmitted carriers is not more than 2 and the number of simultaneously received carriers is not more than 2, which is guaranteed by the UE during scheduling in transmission and/or control nodes.

Example 2: the transmission of one carrier corresponds to the reception of alpha0 carriers.

For example, alpha0=2, transmission on a certain carrier corresponds to reception on 2 carriers, and assuming that the number of carriers that the UE can simultaneously support for transmission is 6, that is, TX limit =6, RX actual limit or RX limit =6/2=3, the UE guarantees during scheduling at the transmission and/or control node, and the number of simultaneously received carriers does not exceed 3.

Example 3: reception of one carrier corresponds to transmission of beta0.

For example, beta0=2, reception on a certain carrier corresponds to transmission on 2 carriers, and assuming that the number of carriers that the UE can simultaneously support for reception is 6, that is, RX limit =6, TX actual limit or TX limit =6/2=3, that is, the UE guarantees during scheduling at the transmission and/or control node that no more than 3 carriers are simultaneously transmitted.

Further alternatively, in the embodiment of the present application, the above-mentioned actual limit is determined based on the first limit.

Further optionally, in this embodiment of the present application, the actual transmission limit is determined based on a first transmission limit and a first predetermined rule;

wherein the first predetermined rule comprises at least one of:

at least one of the actual transmission limits is less than or equal to a first value,

at least one of the actual transmission limits is equal to the second value,

at least one of the actual transmission limits is equal to a third value;

the first value is the minimum of the first transmit limit and the first receive limit;

the second value is determined based on the first transmit limit and the first receive limit;

the third value is determined based on the first transceiving restriction.

It should be noted that, the first predetermined rule may be considered as an association relationship, for example, at least one of the actual transmission limits is less than or equal to a first value, and the actual transmission limit may be considered as being associated with the first transmission limit and the first reception limit; at least one of the actual transmission restrictions is equal to the second value, and the actual transmission restrictions may be considered to have an association relationship with the first transmission restrictions and the first reception restrictions; at least one of the actual transmission limits is equal to the third value, and the actual transmission limit may be considered to be associated with the first transceiving limit.

Illustratively, the control node or the first UE or the second UE guarantees that at least one of the actual transmission limits is smaller than or equal to a first value = min (TX limit, RX limit).

Illustratively, the control node or the first UE or the second UE guarantees that at least one of the actual transmission limits (e.g. TX limit actual or RX limit actual or total limit actual) is equal to the second value.

In one example, the second value = min (a × TX limit, b × RX limit). Wherein a and b can be 0, positive or negative, or decimal.

Example 1: TX limit actual = min (TX limit, RX limit).

Example 2: RX limit actual = min (TX limit, RX limit).

In another example, the second value = c × TX limit + d × RX limit. Wherein c and d can be 0, positive or negative, or decimal.

Illustratively, the control node or the first device or the second UE guarantees that at least one of the actual transmission limits is equal to a third value, the third value = e total limit, e may be a positive number, may be a fractional number.

In the embodiment of the present application, the essence of the transmission method provided in the embodiment of the present application is that the relationship between the transmission limit and the reception limit is constrained so that the relationship matches the relationship between transmission and reception. For example, the maximum number of transmitted carriers is equal to the maximum number of received carriers, so that when the TX RX has correlation, especially when the TX of a certain carrier is correlated to the RX of the carrier or another carrier, the maximum number of actually simultaneously transmitted carriers is equal to the maximum number of actually simultaneously received carriers, thereby avoiding problem 1.

It should be noted that the difference between the limitation of the number of bearer objects and the limitation of the number of resources. For example, the maximum number of bearers that can be sent simultaneously is limited to 2, but multiple PSFCHs may be sent simultaneously on each bearer, and thus the maximum number of resources of the PSFCHs that can be sent actually at the same time may be much larger than 2.

Optionally, in this embodiment, when the first device selects or reports a target resource of the target transmission object, or another UE indicates the target resource, or the control node configures or schedules the target resource, the transmission of the target transmission object does not exceed the target limit (that is, the transmission of the target transmission object is prevented from exceeding the target limit). Wherein the target resource comprises at least one of: candidate resources for the actual transmitted resources. It should be noted that the candidate resource refers to a part of the resource used for actual transmission.

Further optionally, in this embodiment of the application, the target transmission object includes: a first transport object and/or a second transport object; the transmission mode corresponding to the first transmission object is sending, and the transmission mode corresponding to the second transmission object is receiving. It should be noted that the transmission mode corresponding to the first transmission object is sending, which means that the target resource of the first transmission object is used for sending; similarly, the transmission mode corresponding to the second transmission object is reception, which means that the target resource of the second transmission object is used for reception.

Further optionally, in this embodiment of the application, if the target transmission object at least includes the first transmission object, the not-exceeding-target-limit includes at least one of the following:

the corresponding transmission of the first transmission object does not exceed the corresponding target limit;

the expected transmission associated with the first transmission object does not exceed the corresponding target limit;

the expected transmission associated with the first transport object corresponding to the sending of the first transport object does not exceed the corresponding target limit.

Illustratively, the expected transmission associated with the first transmission object includes: and the first transmission object is expected to be sent or received correspondingly. Further, the expected reception corresponding to the first transmission object is: the expected reception corresponding to the transmission of the first transmission object is, similarly, the expected transmission corresponding to the first transmission object is: the transmission corresponding to the first transport object corresponds to the desired transmission.

It should be noted that the sending corresponding to the first transmission object and the expected transmission associated with the first transmission object do not exceed the corresponding target limit means that the total transmission of the sending corresponding to the first transmission object and the expected transmission associated with the first transmission object does not exceed the corresponding target limit. For example, the total number of expected transmissions associated with the first transport object sent for the first transport object does not exceed the corresponding maximum number limit.

Illustratively, if the target resource of the first transport object is used for transmission, the first device or other UE or control node guarantees at least one of:

the target resource or transmission of the first transport object (either simultaneously or within a preset time frame) does not exceed the target limit (e.g., does not exceed TX limit and/or TX limit actual; and/or does not exceed RX limit and/or RX limit actual);

a target resource of the first transport object or an expected transmission (e.g., expected reception) of sending a corresponding third transport association (either simultaneously or within a preset time frame) does not exceed a target limit (e.g., the expected reception of the first transport object association does not exceed RX limit and or RX limit actual).

Further optionally, in this embodiment of the application, if the target transmission object at least includes the second transmission object, the no-exceeding target limit includes at least one of the following:

the corresponding reception of the second transmission object does not exceed the corresponding target limit;

the expected transmission associated with the second transmission object does not exceed the corresponding target limit.

The expected transmission associated with the second transport object is not exceeded by a corresponding receipt of the second transport object.

Illustratively, the expected transmission associated with the second transmission object includes: and the expected sending or the expected receiving corresponding to the second transmission object. Further, the expected reception corresponding to the second transmission object is: the expected reception corresponding to the reception of the second transmission object is, similarly, the expected transmission corresponding to the second transmission object is: the second transmission object corresponds to receiving the corresponding expected transmission.

Illustratively, if the target resource of the second transport object is for reception, the first device or other UE or control node guarantees at least one of:

(either simultaneously or within a preset time frame) the target resource or reception of the second transmission object does not exceed the target limit (e.g., does not exceed the TX limit and/or the TX limit actual; and/or does not exceed the RX limit and/or the RX limit actual);

the target resource of the second transport object or the expected transmission (e.g., expected transmission) of the reception associated fourth transport object does not exceed the target limit (e.g., the expected reception associated with the first transport object does not exceed the TX limit and or the TX limit actual).

Further optionally, in an embodiment of the present application, the target transmission object includes: a first transport object and a second transport object, and said no-more-than-target-limit comprises at least one of:

the sending corresponding to the first transmission object and the receiving corresponding to the second transmission object do not exceed the corresponding target limit;

the expected transmission associated with the first transport object and the expected transmission associated with the second transport object do not exceed the corresponding target limits;

the expected transmission associated with the second transport object sent in correspondence with the first transport object does not exceed the corresponding target limit;

the expected transmission associated with the first transport object is received for the second transport object without exceeding the corresponding target limit.

Illustratively, if the target resource of the first transport object is used for transmission and the target resource of the second transport object is used for reception, the first device or other UE or control node guarantees at least one of:

(simultaneously or within a preset time range) the target resource or transmission of the first transmission object does not exceed the corresponding target limit;

the expected receipt of the target resource of the first transport object or the transmission of the corresponding third transport object (simultaneously or within a preset time range) does not exceed a target limit;

(simultaneously or within a preset time range) the target resource or reception of the second transmission object does not exceed the corresponding target limit;

(simultaneously or within a preset time range) the target resource of the second transport object or the expected transmission of the received corresponding fourth transport object does not exceed a target limit;

at least two of the target resource or transmission of the first transmission object and the target resource or reception of the second transmission object and the target resource or transmission of the first transmission object and the expected reception of the corresponding third transmission object and the target resource or reception of the second transmission object and the expected transmission of the corresponding fourth transmission object do not exceed the corresponding target limits (e.g. do not exceed TX limit and/or TX limit actual, do not exceed RX limit and/or RX limit actual, do not exceed total limit and/or total limit actual).

In one example, the total limit and/or total limit actual may include:

for example, a target resource or transmission of a first transport object and a target resource or reception of a second transport object, and an expected transmission (e.g., an expected transmission) of an associated fourth transport object, do not exceed TX limit and/or TX limit actual (simultaneously or within a preset time frame).

For example, the target resource or reception of the second transport object and the target resource or transmission of the associated third transport object (e.g., the desired reception) do not exceed RX limit and/or RX limit actual (simultaneously or within a preset time frame).

For example, the target resource or transmission of the first transmission object and the target resource or reception of the second transmission object do not exceed (simultaneously or within a preset time range) total limit and/or total limit actual.

For example, a target resource of a first transport object or a desired transmission (e.g., desired reception) to send a corresponding third transport object and a target resource of a second transport object or a desired transmission (e.g., desired transmission) to receive a corresponding fourth transport object do not exceed the total limit and/or the total limit actual (simultaneously or within a preset time frame).
