Technical terms related to the technical solutions provided in the embodiments of the present application will be described in the following by way of example.

(1) Side Link (SL) resource allocation mode

In the related art, there are two New air interface (NR) SL resource allocation manners, one based on base station scheduling (mode 1) and the other based on UE autonomous resource selection (mode 2). For a resource allocation mode of base station scheduling, determining a sidelink resource for data transmission by the UE by the base station, and notifying downlink UE by downlink signaling; for the resource allocation mode of autonomous selection of the UE, the UE selects available transmission resources in a (pre) configured resource pool, the UE firstly monitors a channel before the resource selection, selects a resource set with smaller interference according to a channel monitoring result, and then randomly selects the resources for transmission from the resource set.

For mode 2, the specific operation is as follows:

1) After the resource selection of the downlink UE is triggered, firstly, a Physical (PHY) layer determines a resource selection window, the lower boundary of the resource selection window is at T1 time after the triggering of the resource selection, the upper boundary of the resource selection is at T2 time after the triggering, wherein T1 is a value selected by the UE implementation manner within a range of [ t1_min, t1_max ], T2 is a value selected by the UE implementation manner within a packet delay budget (packet delay budget, PDB) of its TB transmission, and T2 is not earlier than T1.

2) Before the UE selects a resource, the PHY layer needs to determine an alternative resource combination (candidate resource set) of the resource selection, where the number of alternative resource sub-channels (sub-channels) is determined by a Medium Access Control (MAC) layer, and the UE performs resource exclusion on the resource according to a reference signal received power (Reference Signal Received Power, RSRP) measurement estimated on the resource within the resource selection window (e.g., estimated by listening to a physical sidelink control channel (Physical SideLink Control Channel, PSCCH)/physical sidelink shared channel (Physical SideLink Shared Channel, psch)) and a corresponding RSRP threshold (threshold), and cannot include the alternative resource set if the RSRP of the current transmission resource is higher than the RSRP threshold. And after the resource is removed, the remaining resources in the resource selection window form an alternative resource set. The ratio of the resources in the alternative resource set to the resources in the resource selection window is not less than x%, if the ratio is less than x%, the RSRP threshold needs to be increased according to a step value (3 dB), and then the resource exclusion operation is performed until the resources not less than x% can be selected. In addition, the RSRP comparison is related to the priority of the TB to be transmitted and the priority value demodulated on the PSCCH, and the specific process is not repeated.

3) After the alternative resource set is determined, the PHY layer reports the alternative resource set to the MAC layer, the MAC layer randomly selects transmission resources in the alternative resource set, and the number of the selected resources is determined according to the decision of the MAC layer.

(2) Correlation technique of Sidelink in unlicensed spectrum

For SL-U (unlicensed spectrum), the channel needs to be acquired by LBT (Listen Before Talk) before the SL data is sent. The LBT technique is briefly described as follows:

in future communication systems, shared spectrum such as unlicensed band (unlicensed band) may be used as a supplement to licensed band (licensed band) to help operators expand services. To keep pace with NR deployment and maximize as much as possible unlicensed access based on NR, unlicensed bands may operate in the 5GHz,37GHz and 60GHz bands. Since unlicensed bands are shared by multiple technologies (RATs), such as WiFi, radar, LTE-LAA, etc., in some countries or regions, unlicensed bands must meet regulations to ensure that all devices can use the resources fairly, such as LBT, maximum channel occupancy time (maximum channel occupancy time, MCOT), etc. When the transmission node needs to transmit information, LBT needs to be made first, power detection (ED) is performed on surrounding nodes, and when the detected power is lower than a threshold, the channel is considered to be empty (idle), and the transmission node can transmit. Otherwise, the channel is considered as busy, and the transmission node cannot transmit. The transmission node may be a base station, UE, wiFi AP, etc. After the transmission node starts transmission, the occupied channel time COT cannot exceed MCOT. Furthermore, according to Occupied Channel Bandwidth (OCB) regulation, on unlicensed bands, a transmitting node occupies at least 70% (60 GHz) or 80% (5 GHz) of the entire band per transmission.

Types (types) of LBT commonly used in NRU can be classified into Type1, type2A, type2B, and Type2C. Type1 LBT is a channel interception mechanism based on back-off, and when a transmission node detects that a channel is busy, the transmission node performs back-off, and continues interception until the channel is empty. Type2C is that the transmitting node does not make LBT, i.e., no LBT or transmits immediately (immediate transmission). Type2A and Type2B LBT are one-shot LBT, namely, the node makes one LBT before transmission, if the channel is empty, the transmission is carried out, and if the channel is busy, the transmission is not carried out. The difference is that Type2A makes LBT within 25us, which is suitable for use in sharing COT with gap between two transmissions greater than or equal to 25us. While Type2B makes LBT within 16us, it is suitable for the gap between two transmissions to be equal to 16us when sharing COT. In addition, there is Type 2LBT applicable to LAA/eLAA/FeLAA, and when co is shared, the gap between two transmissions is 25us or more, and Type 2LBT may be used by enb and UE. In addition, in the frequency range 2-2, the types of LBT are Type1, type2 and Type3.Type1 are channel listening mechanisms based on back-off, type2 is one-shot LBT, LBT is 5us within 8us, and Type3 is no LBT.

In the related art, before the UE can transmit on the unlicensed spectrum using the selected resources, the UE needs to perform LBT, if LBT failure occurs, the UE cannot transmit on the selected resources, and the UE needs to reselect resources and reserve resources, resulting in waste of reserved resources. To improve the success rate of transmission, the UE may select and reserve more resources, or trigger a resource reselection when LBT failure occurs. That is, this causes excessive unused resources of reserved resources, which results in problems of waste of reserved resources and degradation of spectrum utilization. The application provides a method for reducing excessive unused resources reserved by UE, which can solve the problem of interference/spectrum utilization rate caused by excessive reserved resources of the UE.

In the method, the device, the UE and the readable storage medium for determining transmission resources provided in the embodiments of the present application, the first UE selects the transmission resources according to a first manner and/or reserves the transmission resources according to a second manner; wherein the first mode includes at least one of: the first UE selects N first transmission resources according to a first rule, wherein N is a positive integer; triggering resource reselection by the first UE under the condition that the first condition is met and the LBT fails; under the condition that the first UE monitors that the second UE has SL resource reservation behavior, determining second transmission resources available for SL delay transmission according to the resource reservation information and the first preset transmission power; the second aspect includes at least one of: the first UE releases reserved transmission resources under the condition that the second condition is met; the first UE reserves transmission resources according to a preset reserved transmission resource number threshold. Therefore, the UE can select the transmission resources according to the first mode and reserve the transmission resources according to the second mode, so that excessive resource reselection can be avoided, the excessive reserved transmission resources are released, and the utilization rate of the transmission resources and the reliability of the transmission resources in data transmission are improved.

The technical solution provided in the embodiments of the present application may be applied to unlicensed spectrum scenarios or other scenarios.

The method, the device, the UE and the readable storage medium for determining transmission resources provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through some embodiments and application scenarios thereof.

Fig. 2 is a flow chart illustrating a method for determining transmission resources according to an embodiment of the present application, as shown in fig. 2, the method for configuring resources may include the following step 201:

step 201, the first UE selects transmission resources according to the first manner and/or reserves transmission resources according to the second manner.

In an embodiment of the present application, the first mode includes at least one of:

mode a: the first UE selects N first transmission resources according to a first rule, wherein N is a positive integer;

mode B: triggering resource reselection by the first UE under the condition that the first condition is met and the LBT fails;

mode C: and under the condition that the first UE monitors that the second UE has SL resource reservation behavior, the first UE determines second transmission resources available for SL delay transmission according to the resource reservation information and the first preset transmission power.

In an embodiment of the present application, the second mode includes at least one of the following:

Mode D: the first UE releases reserved transmission resources under the condition that the second condition is met;

mode F: the first UE reserves transmission resources according to a preset reserved transmission resource number threshold.

In one possible embodiment, the first UE may select transmission resources in a first manner and then reserve the transmission resources.

In one possible embodiment, the first UE may reserve transmission resources in a second manner after selecting the transmission resources.

In one possible embodiment, the first UE may reserve transmission resources in the second manner after selecting transmission resources in the first manner.

Optionally, in an embodiment of the present application, for the foregoing manner a, the first rule includes any one of the following:

rule 1: in the case that the third condition is not satisfied, the N first transmission resources satisfy a fourth condition;

rule 2: in the case that the third condition is satisfied, the N first transmission resources need not satisfy the fourth condition. That is, the N first transmission resources may satisfy the fourth condition, or the N first transmission resources may not satisfy the fourth condition.

Illustratively, the number of LBTs performed on the first transmission resource is less than or equal to a preset number.

The preset number of times may be predefined or agreed upon by a protocol or configured or preconfigured on the network side, for example.

Illustratively, the third condition includes at least one of:

the quality of service (Quality of Service, qoS) parameters of the SL data to be transmitted meet preset QoS requirements;

the transmission resource selected by the first UE is located in a channel occupation time (Channel Occupancy Time, COT) of the first UE or a COT shared by other UEs.

The other UEs may be, for example, UEs other than the first UE.

The preset QoS requirement may be that the priority of the current transmission data needs to be greater than a target threshold value.

The target threshold value may be predefined or agreed upon by a protocol or network-side configured or preconfigured, for example.

Illustratively, the fourth condition described above includes any one of:

the time interval between the current time and the resource selection time of the first transmission resource is greater than or equal to a first preset interval;

the time interval between the resource selection time of the N first transmission resources is greater than or equal to the second preset interval.

The first preset interval may be predefined or protocol-agreed or network-side configured or preconfigured, for example.

The second preset interval may be predefined or protocol-agreed or network-side configured or preconfigured, for example.

It should be noted that the first UE has a certain probability of making a type 2LBT, so even if the above first condition is not satisfied, the first UE still has a probability of making SL transmission.

For example, if the QoS parameter of the SL data to be transmitted meets the preset QoS requirement, the first UE may dynamically decrease the time of type-1LBT to complete LBT before reserving the resources.

Optionally, in this embodiment of the present application, for the above manner B, when the first UE monitors that the LBT fails, the resource reselection may be triggered when the first condition is met.

Illustratively, the first condition includes at least one of:

the QoS parameters of the SL data to be transmitted meet preset QoS requirements,

the network congestion level is less than a first preset threshold,

the number of LBT failures exceeds a second preset threshold,

the accumulated time of LBT failure exceeds a third preset threshold;

the window length of the contention window when the first UE performs LBT exceeds a first threshold.

Notably, the triggering of the resource reselection is only allowed if the window length of the contention window when the first UE performs LBT exceeds the first threshold.

Illustratively, the congestion level may be measured by parameters such as a channel busy rate (Channel Busy Ratio, CBR), LBT backoff period, etc.

The first preset threshold may be predefined or protocol-agreed or network-side configured or preconfigured, for example.

The second preset threshold may be predefined or protocol-agreed or network-side configured or preconfigured, for example.

The third preset threshold may be predefined or protocol-agreed or network-side configured or preconfigured, for example.

The first threshold may be predefined or protocol-agreed or network-side configured or preconfigured, for example.

Therefore, by limiting the condition of triggering reselection due to LBT failure, the problem of reserving excessive transmission resources due to transmission resource reselection caused by LBT failure is avoided.

Optionally, in this embodiment of the present application, for the above manner C, in a case that the first UE monitors that the second UE has a SL resource reservation behavior, the first UE may perform SL delay transmission based on the selected transmission resource.

Illustratively, the above-mentioned resource reservation information reserves resource reservation information of the second resource for the second UE.

The first predetermined transmission power is illustratively predefined or protocol-agreed or network-side configured or preconfigured or determined according to ED (Energy Detection Threshold), e.g. equal or proportional to EDT.

The second transmission resource may be used for SL delay transmission, or may be used for conventional SL transmission, for example.

In an exemplary embodiment, when the first UE detects that the total transmission power on the third transmission resource is greater than or equal to the first predetermined transmission power, the first UE performs SL delay transmission on the second transmission resource under the fifth condition.

Illustratively, the third transmission resource is a reserved transmission resource of the second UE, and there is an overlap between the third transmission resource and the second transmission resource.

Illustratively, the fifth condition includes at least: the first UE succeeds in LBT before SL delay transmission.

That is, in case the first UE detects that the total transmission power on the third transmission resource is greater than or equal to the first predetermined transmission power, the second transmission resource may be used for SL delay transmission.

It should be noted that the relative concept of the delayed transmission is as follows: if a transmission has a cyclic prefix extension (Cyclic prefix extension, CPE), a transmission without CPE on the same time unit has a delayed transmission relative to a transmission with CPE; on the same slot, the transmission from the second symbol (symbol) is a delayed transmission relative to the transmission from the first symbol.

Optionally, in an embodiment of the present application, for the above manner D, the above second condition includes at least one of:

the time interval of the reserved transmission resource at the current moment is larger than the LBT duration requirement;

the reserved transmission resources are not within the COT of the first UE or within the COTs shared by other UEs.

Illustratively, the releasing reserved transmission resources may include: after the first UE completes transmission of the first transport block TB, or after the first UE occupies the first channel to transmit the first TB, the first UE releases the transmission resources reserved for the transmission of the first TB.

Optionally, in this embodiment of the present application, with respect to the foregoing manner F, the first UE may reserve transmission resources according to a preset or agreed or network-side configured predetermined reserved transmission resource number threshold.

Illustratively, the total number of transmission resources, total COT time, etc. that the first UE can reserve within a unit time or time window has an upper limit, or the number of times a particular type of LBT is performed has an upper limit

For example, if the number of reserved transmission resources of the first UE has reached the predetermined number of reserved transmission resources threshold, the first UE does not reserve new transmission resources under the condition that the number of reserved transmission resources is not reduced.

The UE may send an indication information indicating that there is uncertainty or delay in transmission on the reserved transmission resources, e.g., when reserving the selected transmission resources.

Thus, by ensuring that the number of reserved transmission resources does not exceed a predetermined threshold, excessive reservation of transmission resources can be avoided.

Optionally, in the embodiment of the present application, the process of the step 201 "the first UE selects the transmission resource according to the first manner" includes the following step 201a:

step 201a, the first UE selects N first transmission resources from M candidate resource subsets.

Illustratively, each of the M candidate subsets corresponds to a reference signal received power (Reference Signal Received Power, RSRP) threshold.

Illustratively, the subset of alternative resources may be partitioned according to an RSRP threshold value on the transmission resources.

Specifically, the RSRP measurement value of the candidate resource in subset 1 is lower than RSRP threshold 1, and the RSRP measurement value of the candidate resource in subset 2 is lower than RSRP threshold 2 (or, the candidate resource that needs to be removed from subset 2 and repeated with subset 1).

The subset of alternative resources may also be partitioned according to transmission resource occupancy values, for example.

Specifically, the proportion of the candidate resources in the subset 1 to the candidate resources in the resource selection window is higher than x1%, and the proportion of the candidate resources in the subset 2 to the candidate resources in the resource selection window is higher than x2% (or, the candidate resources in the subset 2 need to be removed and repeated in the subset 1). The value to be described, where x% may be equivalent to the alternative resource duty cycle used when the PHY layer identifies the alternative resource set.

For example, the first UE may preferentially select transmission resources in the subset with low interference to transmission resources, and if the candidate resources satisfying the resource selection requirement are insufficient, the first UE may select transmission resources in the subset with low interference to transmission resources in the other subsets.

For example, when the first UE performs the charging evaluation or the resource preemption determination, if a suitable candidate resource exists in the subset with lower interference to the resource is found, the first UE may trigger the resource reselection so as to be able to select the resource with lower interference.

For example, for transmission resources selected in the higher subset of transmission resource interference, the first UE determines whether to transmit on the selected resources based on the probability, and/or the first UE delays (based on the probability) its starting position of transmission.

The probability is illustratively associated with the interference level of the transmission resource or with the Qos of the transmission data.

For example, if the priority of transmitting data is high, the UE has a high probability of transmitting on the selected transmission resource; if the priority of the transmission data is higher, the UE has a higher probability of not delaying the transmission starting position.

Optionally, in the embodiment of the present application, the process of the step 201 "the first UE selects the transmission resource according to the first manner" includes the following step 201b:

step 201b, the first UE selects the start time delay resource as the first transmission resource.

Illustratively, the start time delay resource has a predetermined time delay relative to a transmission start position of the reference resource.

The above-mentioned preset delay may be predefined or protocol-agreed or network-side configured or preconfigured, for example.

Illustratively, the interference determination in the selection of the start time delay resource is determined based on the resource reservation information of the start time delay resource.

Optionally, in the embodiment of the present application, in the step 201b "the first UE may select the start time delay resource as the first transmission resource", the following step 201b1 is included:

In step 201b1, the first UE selects a start time delay resource as the first transmission resource when the sixth condition or the seventh condition is satisfied.

Illustratively, the sixth condition includes at least one of:

the RSRP measured value on the conventional transmission resource which is reserved by the first UE and overlapped with the initial time delay resource is larger than or equal to a second preset threshold value;

the total transmission power on the regular transmission resources reserved by the first UE overlapping the start time delay resources is greater than or equal to the second transmission power.

Illustratively, the second transmission power is associated with EDT.

Illustratively, the seventh condition includes at least one of:

the first UE autonomously decides;

alternative conventional resources are not sufficient;

the first UE triggers a resource reselection due to a resource selection reevaluation or a resource preemption detection.

Optionally, in the embodiment of the present application, after the foregoing step 201b "the first UE selects the start time delay resource as the first transmission resource", the method for determining the transmission resource provided in the embodiment of the present application further includes step 301:

step 301, the first UE generates a resource reservation signaling.

Illustratively, the resource reservation signaling is used to reserve the start time delay resource.

Therefore, the UE can determine the transmission resources through the first rule, the probability of LBT failure is reduced, and the problem that excessive transmission resources are reserved due to reselection of the transmission resources caused by the LBT failure is avoided.

Optionally, in the embodiment of the present application, the method for determining transmission resources provided in the present application further includes the following step 401:

step 401, UE sends first information.

Illustratively, the first information is used to indicate that the first reserved transmission resources have been released.

Illustratively, the first information includes at least one of:

the resource release indication signaling is used to indicate,

the LBT duration reference information is used to determine,

COT duration reference information;

wherein, the LBT duration reference information includes: type 1LBT remaining time; the above-mentioned COT duration reference information includes: the remaining duration of the COT of the UE, or the remaining duration of the COT shared by other UEs.

The above-mentioned resource release indication signaling may be, for example, a sidelink control information (Sidelink Control Information, SCI), a medium access control element (Medium Access Control Control Element, MAC CE), a sidelink feedback control information (Sidelink Feedback Control Information, SFCI), a physical sidelink feedback control channel (Physical SideLink Feedback Channel, PSFCH) carrying the resource release indication information.
