Description

Technical Field

[0001] The present application belongs to the field of communication technology, and specifically relates to a resource processing method, a resource processing device and a terminal. Background Art

[0002] The resource allocation of the New Radio (NR) SideLink (SL) has at least two modes: mode 1 and mode 2. For mode 1, the control node will allocate transmission resources to the terminal, and for mode 2, the terminal will autonomously select transmission resources.

[0003] In the Mode 2 resource allocation mode, the resource preemption mechanism is supported. According to the SL preemption operation, if the resources selected / reserved by the terminal are preempted by other terminals, it is necessary to reselect the resources so that the preempted terminal can perform transport block (TB) transmission on the reselected resources to avoid transmission collision / interference problems. However, in the prior art, there is no solution for how to determine whether the resources selected / reserved by the terminal are preempted, that is, how to re-evaluate the resources selected / reserved by the terminal. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a resource processing method, a resource processing device and a terminal, which can realize the re-evaluation of the resources selected / reserved by the terminal, and solve the problem of low transmission reliability caused by the inability to re-evaluate the resources selected / reserved by the terminal.

[0005] In order to solve the above technical problems, this application is implemented as follows:

[0011] The first resource reservation information is sent at the second moment, and the first moment is before the second moment; the second reserved resources are non-periodic resources, and the third reserved resources are resources within a resource period of periodic resources.

[0012] In a second aspect, a resource processing device is provided, which is applied to a terminal, and the resource processing device includes:

[0015] The second reserved resource indicated by the first resource reservation information;

[0016] The third reserved resource indicated by the first resource reservation information;

[0017] The first resource reservation information is sent at the second moment, and the first moment is before the second moment; the second reserved resources are non-periodic resources, and the third reserved resources are resources within a resource period of periodic resources.

[0018] In a third aspect, a terminal is provided, comprising a processor, a memory, and a program or instruction stored in the memory and executable on the processor, wherein the program or instruction, when executed by the processor, implements the steps of the method described in the first aspect.

[0019] In a fourth aspect, a readable storage medium is provided, on which a program or instruction is stored. When the program or instruction is executed by a processor, the steps of the method described in the first aspect are implemented.

[0033] For ease of understanding, some contents involved in the embodiments of the present application are described below:

[0034] 1. SideLink (SL) resource preemption

[0035] NR Sidelink resource allocation has at least two modes: mode 1 and mode 2. For mode 1, the control node allocates transmission resources to the UE, and for mode 2, the UE independently selects transmission resources.

[0036] In Mode 2 resource allocation mode, the resource pre-emption mechanism is supported, which is briefly described as follows: if the resources reserved / selected by a UE overlap (partially overlap) with the resources reserved / selected by other UEs with higher priority services, the UE will trigger resource reselection if the SL Reference Signal Received Power (RSRP) measurement value on the relevant resources is greater than a certain associated SL-RSRP (associated SL-RSRP) threshold value. The service priority and the SL-RSRP threshold are determined by the transport block (TB) transmission on the resources.

[0037] In order to determine whether a reserved / selected resource is preempted, the UE re-evaluates the resource selection at least at time m-T3, where time m is the time when the resource is located or the time when the resource reservation information indicating the resource is sent, and T3 at least includes the duration of the UE's resource selection process. The resource can be: Physical Sidelink Control Channel (PSCCH) or Physical Sidelink Shared Channel (PSSCH) resources, etc.

[0038] 2. Sidelink resource reservation.

[0039] The UE can reserve its allocated resources (reservation is divided into periodic reservation and non-periodic reservation), and the reserved resources are used for future PSCCH or PSSCH transmission.

[0040] The non-periodic reservation can be realized through the Time Resource Assignment field in the Sidelink Control Information (SCI), and the reserved resources can at least be used for the transmission of the same TB.

[0041] Periodic reservation can be implemented through the Resource Reservation Period field in the SCI. The periodic resources reserved in the current period can be used for at least the transmission of the next TB.

[0042] The resource processing method provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0043] See also Figure 1 , Figure 1 The resource processing method of the embodiment of the present application can be applied to a terminal.

[0044] like Figure 1 As shown, the resource processing method may include the following steps:

[0045] Step 101: re-evaluate the target resource at a first moment.

[0046] That is to say, at the first moment, it is determined whether the target resource reserved by the terminal is preempted.

[0047] In the embodiment of the present application, the target resource may include at least one of the following:

[0048] a first reserved resource corresponding to a second moment;

[0049] The second reserved resource indicated by the first resource reservation information;

[0050] The third reserved resource indicated by the first resource reservation information;

[0051] The first resource reservation information is sent at the second moment, and the first moment is before the second moment; the second reserved resources are non-periodic resources, and the third reserved resources are resources within a resource period of periodic resources.

[0052] Furthermore, the interval between the first moment and the second moment may be greater than or equal to the processing time of resource reselection, so that when the evaluation result of the re-evaluation is that the target resource needs to be reselected, that is, when the target resource is preempted, the terminal may reselect the resource at the second moment or before the second moment, which may avoid transmission collision / interference problems, thereby improving transmission reliability. Of course, in other implementations, the interval between the first moment and the second moment may be greater than a certain threshold, which may be agreed upon by the protocol, configured by the control node, or pre-configured by the terminal, and may be specifically set according to actual needs, and the embodiments of the present application do not limit this.

[0053] In specific implementation, the reservation of the second reserved resource can be implemented through the time resource allocation (Time Resource Assignment) domain; the reservation of the third reserved resource can be implemented through the resource reservation period (Resource Reservation Period) domain. Furthermore, the third reserved resource may include part or all of the resources within the next / multiple resource periods of the periodic resource. It should be noted that in an embodiment of the present application, the next / multiple resource periods can be understood as: the next / multiple resource periods of the current resource period, and the current resource period may be the resource period in which the first reserved resource is located. The one periodic resource can be obtained by shifting a resource in the time domain, and the time domain step of the shift is the length of a resource period. One resource period of the periodic resource may include one / multiple periodic resources.

[0054] The first reserved resource corresponding to the second moment can be understood as: the second moment is the moment where the first reserved resource is located. Optionally, the first reserved resource belongs to a periodic resource, and the first reserved resource can be a resource within a resource period of the periodic resource.

[0055] During implementation, for the second reserved resources and the third reserved resources indicated by the first resource reservation information: in the first implementation mode, the terminal may only re-evaluate the second reserved resources; in the second implementation mode, the terminal may evaluate the second reserved resources and the third reserved resources.

[0056] In the resource processing method of the embodiment of the present application, the terminal can re-evaluate the target resource at the first moment, and the target resource includes at least one of the following: the first reserved resource corresponding to the second moment; the second reserved resource indicated by the first resource reservation information; the third reserved resource indicated by the first resource reservation information; wherein the first resource reservation information is sent at the second moment, and the first moment is before the second moment; the second reserved resource is a non-periodic resource, and the third reserved resource is a resource within the resource period of the periodic resource. It can be seen that the embodiment of the present application can realize the re-evaluation of the resources selected / reserved by the terminal, thereby avoiding transmission collision / interference problems and improving the reliability of transmission.

[0057] The third reserved resource in the embodiment of the present application is described below.

[0058] Optionally, the resource period of the third reserved resource is less than or equal to a first threshold, and the first threshold is agreed upon by a protocol, configured by a control node, or pre-configured by the terminal.

[0059] In this optional implementation, whether the terminal re-evaluates the periodic reserved resources indicated by the first resource reservation information may depend on whether the resource period of the periodic reserved resources indicated by the first resource reservation information is less than the first threshold. Specifically, for periodic resources whose resource period is less than the first threshold, the terminal may re-evaluate them; for periodic resources whose resource period is greater than or equal to the first threshold, the terminal may not re-evaluate them. In this way, the terminal can clearly know whether to re-evaluate the third reserved resources, thereby improving the reliability of transmission.

[0060] In another optional implementation manner, whether the terminal re-evaluates the periodic reserved resources indicated by the first resource reservation information may depend on whether the resource period of the periodic reserved resources indicated by the first resource reservation information is less than or equal to the first threshold. Specifically, for periodic resources whose resource period is less than or equal to the first threshold, the terminal may re-evaluate them; for periodic resources whose resource period is greater than the first threshold, the terminal may not re-evaluate them. In this way, the terminal can clearly know whether to re-evaluate the third reserved resources, thereby improving the reliability of transmission.

[0061] Optionally, it is assumed that the characteristics of the first transmission block TB transmitted on the third reserved resources are the same as the characteristics of the second TB transmitted on the first reserved resources; or, it is assumed that the characteristics of the first TB are predetermined by a protocol, configured by a control node, or preconfigured by the terminal.

[0062] In this optional implementation, the terminal may decide whether to re-evaluate the third reserved resource based on any one of the above assumptions. In specific implementation, if any one of the above assumptions is true, the terminal may re-evaluate the third reserved resource, otherwise the terminal may not re-evaluate the third reserved resource. In this way, the terminal can clearly know whether to re-evaluate the third reserved resource, thereby improving the reliability of transmission.

[0063] During implementation, the above-mentioned characteristics of the TB may include some or all characteristics of the TB. Optionally, the characteristics of the TB include at least one of the following: the priority of the TB mapped on the resource, the packet delay budget (PDB) of the TB. Furthermore, the priority of the TB mapped on the resource may include at least one of the following: the priority of the TB mapped on the PSSCH, the priority of the TB mapped on the PSCCH. Specifically, when the TB is transmitted on the PSSCH, the priority indicated by the PSCCH (associated PSCCH) / SCI corresponding to the PSSCH is the priority of the TB mapped on the resource.

[0064] Exemplary: Under the assumption that the characteristics of the first TB are predetermined by a protocol, configured by a control node or pre-configured by the terminal, it can be assumed that the priority mapped by the first TB on the PSSCH or PSCCH is a maximum value, a minimum value, a configured value or a pre-configured value, or, it can be assumed that the PDB characteristics of the first TB are a fixed value, a configured value or a pre-configured value.

[0065] The following describes a case where the target resource includes the first reserved resource.

[0066] Optionally, when the target resource includes the first reserved resource, the re-evaluating the target resource at the first moment includes:

[0067] When the first condition is met, the target resource is re-evaluated at the first moment, and the first condition includes any one of the following:

[0068] a) the terminal has a TB to be transmitted at the first moment;

[0069] b) the terminal has TB to be transmitted before the first moment;

[0070] c) the terminal has no TB to be transmitted on the first reserved resource;

[0071] The TB to be transmitted is a TB configured to be transmitted on the first reserved resources.

[0072] In this optional implementation, the terminal re-evaluates the first reserved resources at the first moment in two scenarios: Scenario 1: when the first conditions include a) and b), the first reserved resources are re-evaluated at the first moment; Scenario 2: when the first conditions include c), the first reserved resources are re-evaluated at the first moment.

[0073] For scenario one, if the terminal has a TB to be transmitted no later than the first moment, that is, the TB to be transmitted arrives no later than the first moment, the terminal may re-evaluate the first reserved resources at the first moment.

[0074] For scenario 2, optionally, when the first condition is satisfied including that the terminal does not have a TB to be transmitted on the first reserved resource:

[0075] Assume that the characteristics of the third TB transmitted on the first reserved resource are the same as the characteristics of the fourth TB; or, assume that the characteristics of the third TB are agreed upon by a protocol or configured by a control node or pre-configured by the terminal;

[0076] The fourth TB satisfies at least one of the following conditions: the fourth TB and the third TB belong to the same sub-link process (SL Process), and the fourth TB is a previous TB of the third TB.

[0077] The above-mentioned characteristics of TB may include some or all characteristics of TB. For details, please refer to the above description of the characteristics of TB, which will not be repeated here.

[0078] In implementation, the fourth TB may be the TB transmitted before the TB, and further, the fourth TB may belong to the same sub-link process as the third TB; the fourth TB may also belong to a different sub-link process than the third TB. In the case where the fourth TB may belong to the same sub-link process as the third TB, the fourth TB may be the first n transmitted TBs of the third TB, where n is a positive integer.

[0079] In scenario 2, the terminal may decide whether to re-evaluate the first reserved resource according to any of the above assumptions. In specific implementation, if any of the above assumptions is true, the terminal may re-evaluate the first reserved resource, otherwise the terminal may not re-evaluate the first reserved resource.

[0080] In an embodiment of the present application, after the terminal re-evaluates the target resource, for resources that have not been preempted, the terminal can perform TB transmission on the resource; for resources that have been forcibly occupied, the terminal can perform corresponding operations to improve the reliability of transmission, as described below.

[0081] Implementation method 1: Optionally, after re-evaluating the target resource at the first moment, the method further includes:

[0082] When the evaluation result of the re-evaluation is that resource reselection of the third reserved resource is required, performing a first operation, wherein the first operation includes any one of the following:

[0083] reselecting the periodic resource to which the third reserved resource belongs;

[0084] reselecting all periodic resources included in the first sub-link process;

[0085] prohibiting the reservation of the third reserved resource in the first reserved resource;

[0086] Release the first secondary link process;

[0087] The first secondary link process is the secondary link process to which the third reserved resources belong.

[0088] In this implementation manner, the third reserved resource is preempted, and the terminal can avoid transmission collision / interference problems by executing the first operation, thereby improving transmission reliability.

[0089] In the scenario of reselecting the periodic resources to which the third reserved resources belong and reselecting all periodic resources included in the first sub-link process, the terminal performs resource reselection to perform TB transmission on the reselected resources, thereby avoiding transmission collision / interference problems and improving transmission reliability.

[0090] In a scenario where reserving the third reserved resource in the first reserved resource is prohibited, the resource reservation period (Resource Reservation Period) field can be set to 0, so that the third reserved resource will not be reserved in the first reserved resource, thereby avoiding transmission collision / interference problems and improving transmission reliability.

[0091] In the scenario of releasing the first sub-link process, since the first sub-link process is released, the terminal will not use the third reserved resources to execute the first sub-link process, thereby avoiding transmission collision / interference problems and improving transmission reliability.

[0092] Implementation method 2: Optionally, after re-evaluating the target resource at the first moment, the method further includes:

[0093] If the evaluation result of the re-evaluation is that the first reserved resource needs to be reselected, a second operation is performed, where the second operation includes any one of the following:

[0094] releasing the first reserved resources;

[0095] The secondary link process to which the first reserved resources belong is released.

[0096] In this implementation manner, the first reserved resources are preempted, and the terminal can avoid transmission collision / interference problems by performing the second operation, thereby improving transmission reliability.

[0097] In the scenario where the first reserved resources are released, the terminal will not perform TB transmission on the first reserved resources, thereby avoiding transmission collision / interference problems and improving transmission reliability.

[0098] In the scenario where the sub-link process to which the first reserved resources belong is released, the terminal will not use the first reserved resources to execute the first sub-link process, thereby avoiding transmission collision / interference problems and improving transmission reliability.

[0099] Implementation method three: Optionally, after re-evaluating the target resource at the first moment, the method further includes:

[0100] If the evaluation result of the re-evaluation is that the target resource needs to be reselected, reselect the resource to obtain a fourth reserved resource;

[0101] According to a first rule, determining whether to periodically reserve the fourth reserved resource, the first rule comprising at least one of the following:

[0102] 1) The terminal decides whether to periodically reserve the reselected resources;

[0103] 2) Determine whether to periodically reserve the reselected resources according to the second condition, wherein, if the second condition is met, the reselected resources are periodically reserved, and the second condition includes at least one of the following: the number of transmission resources in a resource cycle is less than or equal to a second threshold, and the second threshold is the maximum number of resources allowed in the resource cycle or the maximum number of transmissions allowed for a TB; the channel busy ratio (CBR) is less than a third threshold, and the third threshold is agreed upon by the protocol or configured by the control node or pre-configured by the terminal. Specifically, the number of transmission resources in a resource cycle may be the number of transmission resources in the next resource cycle.

[0104] Optionally, the maximum number of resources allowed in the above-mentioned resource period and the maximum number of transmissions allowed for a TB may be limited by each resource pool (pool) or each bandwidth part (Bandwidth Part, BWP), that is, the maximum number of resources allowed in the above-mentioned resource period and the maximum number of transmissions allowed for a TB may be the maximum number of resources allowed in the above-mentioned resource period and the maximum number of transmissions allowed for a TB of each pool or BWP.

[0105] In this implementation, the target resource is preempted, and the terminal performs resource reselection to obtain the fourth reserved resource. The target resource in this implementation may include one or more of the first reserved resource, the second reserved resource, and the third reserved resource.

[0106] In this implementation manner, after acquiring the reselected resource, ie, the fourth reserved resource, the terminal may determine whether to periodically reserve the reselected resource according to the first rule.

[0107] In the scenario where the first rule includes 1), the terminal can independently decide whether to periodically reserve the reselected resources. If the terminal decides to periodically reserve the reselected resources, that is, to allow periodic reservation, the terminal can periodically reserve the fourth reserved resources, otherwise the fourth reserved resource part is periodically reserved.

[0108] In the scenario where the first rule includes 2), when the second condition is met, the terminal may periodically reserve the fourth reserved resource; otherwise, the terminal may periodically reserve the fourth reserved resource portion.

[0109] During implementation, if the number of transmission resources in a resource period is less than or equal to the second threshold, the terminal may periodically reserve the fourth reserved resource, otherwise the fourth reserved resource portion is periodically reserved. If the CBR is less than the third threshold, the terminal may periodically reserve the fourth reserved resource, otherwise the fourth reserved resource portion is periodically reserved.

[0110] It should be noted that, in some implementations, if the number of transmission resources in a resource period is less than or equal to the second threshold, or the CBR is less than the third threshold, the terminal may periodically reserve the fourth reserved resource.

[0111] Through the above manner, after reselecting resources, the terminal may periodically reserve the reselected resources or may not periodically reserve the reselected resources, thereby improving the flexibility of resource reselection.

[0112] It should be noted that the various optional implementation modes introduced in the embodiments of the present invention may be implemented in combination with each other or may be implemented separately, and the embodiments of the present invention are not limited to this.

[0113] For easier understanding, the following examples are combined with scenario 1 and scenario 2:

[0114] Scenario 1: The UE determines whether the reserved resources of the next resource period are occupied in the previous resource period (i.e., re-evaluates the reserved resources of the next resource period). Figure 2a shown.

[0115] Scenario 2: When the reserved resources in a certain resource period have no corresponding TB transmission, the UE re-evaluates the reserved resources, such as Figure 2b shown.

[0116] Solution 1: This solution targets scenario 1 and explains how to re-evaluate periodically reserved resources.

[0117] 1) For a certain TB transmission, the transmission resources (PSCCH / PSSCH resources) corresponding to time m need to be evaluated for resource selection at time 'm-T3' (reselection is possible after evaluation), and the resources reserved at time m also need to be evaluated for resource selection (reselection is possible after evaluation), and the reserved resources include at least one of the following:

[0118] Only non-periodic reserved resources are evaluated;

[0119] Evaluate resources for both aperiodic and periodic reservations.

[0120] In addition, whether to evaluate the periodically reserved resources may depend on whether the reservation period is less than a certain threshold, and the threshold may at least be defined / controlled node configured / pre-configured.

[0121] 2) Perform resource selection evaluation for determining periodic reserved resources (ie, determine in the current cycle whether resources in subsequent cycles are preempted).

[0122] The assumption of the TB transmitted by the periodically reserved resources is:

[0123] The characteristics (or part of the characteristics) of the TB are the same as the characteristics (or part of the characteristics) of the TB transmitted in the current period, such as the priority mapped by the TB on the PSSCH / PSCCH, the PDB characteristics of the TB, etc.;

[0124] The characteristics (or part of the characteristics) of TB are characteristics agreed upon / configured / pre-configured by the protocol. For example, the priority mapped by TB on PSSCH / PSCCH is the maximum value / minimum value / (pre)configured value, and the PDB characteristic of TB is a fixed value (pre)configured value.

[0125] 3) If it is determined that the periodically reserved resources need to be reselected, perform at least one of the following actions:

[0126] Reselect the corresponding resources of the current cycle;

[0127] The resources requiring resource reselection cannot be reserved in the current cycle (ie, the cycle reservation field of SCI is set to 0);

[0128] Release the SL process that requires resource reselection.

[0129] Solution 2: This solution targets scenario 2 and explains how to re-evaluate periodically reserved resources.

[0130] 1) For the transmission resources (PSCCH / PSSCH resources) at time m, the conditions for resource selection evaluation at time 'm-T3' (or the conditions for reselection after evaluation):

[0131] No later than time 'm-T3', there is TB transmission (ie, TB arrival is no later than time m-T3).

[0132] 2) If there is no TB transmission on the currently reserved resources, the UE also performs resource selection evaluation.

[0133] The assumptions for transferring TB are:

[0134] The characteristics (or part of the characteristics) of the TB are the same as the characteristics (or part of the characteristics) of the TB transmitted last time, such as the priority mapped by the TB on the PSSCH / PSCCH, the PDB characteristics of the TB, etc.;

[0135] The characteristics (or part of the characteristics) of the TB are the same as the characteristics (or part of the characteristics) of the TB transmitted in the previous SL process, such as the priority of the TB mapped on the PSSCH / PSCCH, the PDB characteristics of the TB, etc.;

[0136] The characteristics (or part of the characteristics) of TB are the characteristics agreed / configured / pre-configured by the protocol. For example, the priority mapped by TB on PSSCH / PSCCH is the maximum / minimum / (pre)configured value, and the PDB characteristic of TB is a fixed value (pre)configured value.

[0137] 3) If it is determined that the reserved resources need to be reselected

[0138] Release the current resources that need to be reselected;

[0139] Release the SL process that requires resource reselection.

[0140] Solution 3: This solution explains whether the reselected resources can be reserved periodically to solve the problem of over-reservation of resources.

[0141] When evaluating resource preemption, if the transmission resources (PSCCH / PSSCH resources) of the current period are reselected according to the re-evaluation results, then it is determined whether the reselected resources need to be reserved for the period in the following manner:
