[0001] Cross-reference to related applications

[0002] The present application claims priority from Chinese Patent Application No. 202010454315.9 filed on May 26, 2020, the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0003] The present application belongs to the field of communication technology, and particularly relates to a resource processing method, a resource processing apparatus and a terminal. BACKGROUND

[0004] There are at least two modes of mode 1 and mode 2 for resource allocation of a new radio (NR) side link (SL). For the mode 1 mode, a control node allocates transmission resources for a terminal, and for the mode 2 mode, the terminal autonomously selects transmission resources.

[0005] In the mode 2 resource allocation mode, a resource pre-emption mechanism is supported. According to the SL pre-emption operation, if the resources selected / reserved by the terminal are pre-empted by other terminals, the terminal needs to reselect resources to 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 pre-empted, i.e., how to reevaluate the resources selected / reserved by the terminal.

However, the following description describes a New Radio (NR) system for example purposes, and NR terminology is used in most of the following description, although these techniques can also be applied to applications other than NR system applications, such as 6th Generation (6G) communication systems.

[0036] For the convenience of understanding, some contents related to the embodiments of the present application are described as follows:

[0037] I. SideLink (SL) resource pre-emption.

[0038] There are at least two modes, mode 1 and mode 2, for resource allocation of NR Sidelink. For mode 1, the control node allocates transmission resources for the UE, and for mode 2, the UE autonomously selects transmission resources.

[0039] In the mode 2 resource allocation mode, a resource pre-emption mechanism is supported, and a brief description of the mechanism is as follows: the resources reserved / selected by a UE and the resources reserved / selected by other UEs with higher priority services overlap (partially overlap), and if the SL reference signal received power (RSRP) measurement value of the UE on the relevant resources is greater than a certain associated SL-RSRP threshold, the UE triggers reselection of resources. The service priority and the SL-RSRP threshold are determined by the transmission of a transport block (TB) on the resources.

[0040] In order to determine whether the reserved / selected resource is preempted, the UE re-evaluates the resource selection at least at m-T3, where m is the time of the resource or the time of sending the resource reservation information indicating the resource, and T3 includes at least the duration of the resource selection process of the UE. The resource can be a physical sidelink control channel (PSCCH) or a physical sidelink shared channel (PSSCH) resource, etc.

[0041] II. Resource reservation of sidelink

[0042] The UE can perform resource reservation (including periodic reservation and aperiodic reservation) on the allocated resource, and the reserved resource is used for subsequent PSCCH or PSSCH transmission.

[0043] The aperiodic reservation can be implemented by a time resource assignment (Time Resource Assignment) field in sidelink control information (SCI), and the reserved resource can be used for transmission of the same TB.

[0044] The periodic reservation can be implemented by a resource reservation period (Resource Reservation Period) field in SCI, and the periodically reserved resource can be used for transmission of the next TB.

[0045] The resource processing method provided in the embodiments of the present application will be described in detail in combination with the accompanying drawings, specific embodiments and application scenarios.

[0046] Referring to FIG. 1, FIG. 1 is a flowchart of the resource processing method provided in the embodiments of the present application. The resource processing method of the embodiments of the present application can be applied to a terminal.

[0047] As shown in FIG. 1, the resource processing method can include the following steps:

[0048] Step 101, re-evaluating a target resource at a first time.

[0049] That is, determining whether the target resource reserved by the terminal is preempted at the first time.

[0050] In the embodiments of the present application, the target resource can include at least one of the following:

[0051] a first reserved resource corresponding to a second time;

[0052] the second reserved resource indicated by the first resource reservation information;

[0053] the third reserved resource indicated by the first resource reservation information;

[0054] The first resource reservation information is sent at the second time, and the first time is before the second time. The second reserved resource is an aperiodic resource, and the third reserved resource is a resource in a resource period of a periodic resource.

[0055] Further, the interval between the first time and the second time can be greater than or equal to the processing time of resource reselection, so that in the case where the evaluation result of the reevaluation is that resource reselection is needed for the target resource, i.e., the target resource is preempted, the terminal can perform resource reselection at or before the second time, and transmission collision / interference problems can be avoided, thereby improving the reliability of transmission. Of course, in other embodiments, the interval between the first time and the second time can be greater than a certain threshold, which can be agreed by a protocol, configured by a control node, or preconfigured by the terminal, and can be set according to actual needs. The embodiments of the present application do not limit this.

[0056] In a specific implementation, the reservation of the second reserved resource can be implemented by a time resource assignment (Time Resource Assignment) field, and the reservation of the third reserved resource can be implemented by a resource reservation period (Resource Reservation Period) field. Further, the third reserved resource can include part or all of the resources in the next resource period(s) of the periodic resource. It should be noted that in the embodiments of the present application, the next resource period(s) can be understood as the next resource period(s) of the current resource period, and the current resource period can be the resource period in which the first reserved resource is located. One periodic resource can be obtained by shifting one resource in the time domain, and the time domain step of the shift is the length of one resource period. One resource period of the periodic resource can include one / multiple periodic resources.

[0057] The first reserved resource corresponding to the second time can be understood as the time at which the second time is the first reserved resource. Optionally, the first reserved resource belongs to a periodic resource, and the first reserved resource can be one resource in a resource period of a periodic resource.

[0058] In implementation, for the second reserved resource and the third reserved resource indicated by the first resource reservation information: in a first implementation, the terminal can only perform reevaluation on the second reserved resource; and in a second implementation, the terminal can perform evaluation on the second reserved resource and the third reserved resource.

[0059] The resource processing method of the embodiments of the present application can reevaluate the target resource at the first time, and the target resource includes at least one of the following: the first reserved resource corresponding to the second time; 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 time, and the first time is before the second time; the second reserved resource is an aperiodic resource, and the third reserved resource is a resource in a resource period of a periodic resource. It can be seen that the embodiments of the present application can realize reevaluation of the resources selected / reserved by the terminal, and can further avoid transmission collision / interference problems and improve transmission reliability.

[0060] The third reserved resource in the embodiments of the present application is described below.

[0061] Optionally, the resource period of the third reserved resource is less than or equal to a first threshold, and the first threshold is agreed by a protocol, configured by a control node, or preconfigured by the terminal.

[0062] In the optional embodiment, whether the terminal reevaluates the periodic reserved resource indicated by the first resource reservation information can depend on whether the resource period of the periodic reserved resource indicated thereby is less than the first threshold. Specifically, for a periodic resource with a resource period less than the first threshold, the terminal can reevaluate it; and for a periodic resource with a resource period greater than or equal to the first threshold, the terminal can not reevaluate it. In this way, the terminal can explicitly know whether to reevaluate the third reserved resource, thereby improving transmission reliability.

[0063] In another optional embodiment, whether the terminal reevaluates the periodic reserved resource indicated by the first resource reservation information can depend on whether the resource period of the periodic reserved resource indicated thereby is less than or equal to the first threshold. Specifically, for a periodic resource with a resource period less than or equal to the first threshold, the terminal can reevaluate it; and for a periodic resource with a resource period greater than the first threshold, the terminal can not reevaluate it. In this way, the terminal can explicitly know whether to reevaluate the third reserved resource, thereby improving transmission reliability.

[0064] Optionally, it is assumed that the characteristics of a first transport block (TB) transmitted on the third reserved resource are the same as the characteristics of a second TB transmitted on the first reserved resource; 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.

[0065] In the optional implementation, the terminal can determine whether to reevaluate the third reserved resource according to any of the above assumptions. In implementation, if any of the above assumptions is true, the terminal can reevaluate the third reserved resource, otherwise the terminal can not reevaluate the third reserved resource. In this way, the terminal can explicitly know whether to reevaluate the third reserved resource, thereby improving the reliability of transmission.

[0066] In implementation, the characteristics of the TB can include part or all of the characteristics of the TB. Optionally, the characteristics of the TB include at least one of the following: priority of the TB mapping on the resource, packet delay budget (PDB) of the TB. Further, the priority of the TB mapping on the resource can include at least one of the following: priority of the TB mapping on the PSSCH, priority of the TB mapping on the PSCCH. Specifically, when the TB is transmitted on the PSSCH, the priority indicated by the associated PSCCH / SCI of the PSSCH is the priority of the TB mapping on the resource.

[0067] For example, in the case of assuming that the characteristics of the first TB are predetermined by the protocol, configured by the control node, or preconfigured by the terminal, it can be assumed that the priority of the first TB mapping on the PSSCH or the PSCCH is the maximum value, the minimum value, the configured value, or the preconfigured value, or it can be assumed that the PDB characteristics of the first TB are fixed value, configured value, or preconfigured value.

[0068] The following describes the case where the target resource includes the first reserved resource.

[0069] Optionally, in the case where the target resource includes the first reserved resource, the reevaluation of the target resource at the first time includes:

[0070] In the case where the first condition is met, the target resource is reevaluated at the first time, and the first condition being met includes any of the following:

[0071] a) The terminal has a TB to be transmitted at the first time;

[0072] b) The terminal has a TB to be transmitted before the first time;

[0073] c) The terminal does not have a TB to be transmitted on the first reserved resource;

[0074] Wherein, the TB to be transmitted is a TB configured to be transmitted on the first reserved resource.

[0075] In the optional embodiment, the terminal re-evaluating the first reserved resource at the first time can be divided into two scenarios: scenario one, the terminal re-evaluates the first reserved resource at the first time when the first condition satisfies a) and b); scenario two, the terminal re-evaluates the first reserved resource at the first time when the first condition satisfies c).

[0076] For scenario one, if there is a TB to be transmitted no later than the first time, i.e., the TB to be transmitted arrives no later than the first time, the terminal can re-evaluate the first reserved resource at the first time.

[0077] For scenario two, optionally, when the first condition satisfies that the terminal has no TB to be transmitted on the first reserved resource:

[0078] Suppose that the third TB transmitted on the first reserved resource has the same characteristics as the fourth TB; or, suppose that the characteristics of the third TB are agreed by the protocol or configured by the control node or pre-configured by the terminal;

[0079] Wherein, the fourth TB satisfies at least one of the following: the fourth TB belongs to the same SL process as the third TB, and the fourth TB is a TB transmitted before the third TB.

[0080] The characteristics of the above-mentioned TB can include part or all of the characteristics of the TB. For details, refer to the foregoing description of the characteristics of the TB, which will not be repeated here.

[0081] In implementation, the fourth TB can be a TB transmitted before the TB, and further, the fourth TB can belong to the same SL process as the third TB; the fourth TB can also belong to a different SL process from the third TB. In the case where the fourth TB belongs to the same SL process as the third TB, the fourth TB can be a TB transmitted before the third TB for n times, where n is a positive integer.

[0082] In scenario two, the terminal can decide whether to re-evaluate the first reserved resource according to any of the above-mentioned assumptions. In specific implementation, if any of the above-mentioned assumptions is true, the terminal can re-evaluate the first reserved resource, otherwise the terminal can not re-evaluate the first reserved resource.

[0083] In the embodiments of the present application, after the terminal re-evaluates the target resource, for the resource that is not pre-empted, the terminal can perform TB transmission on the resource; for the resource that is pre-empted, the terminal can perform corresponding operations to improve the reliability of transmission, which will be described in detail as follows.

[0084] In an implementation, after the re-evaluation of the target resource at the first time, the method further comprises:

[0085] In a case where the evaluation result of the re-evaluation indicates that the third reserved resource needs to be re-selected, a first operation is performed, and the first operation comprises any one of the following:

[0086] re-selecting a periodic resource to which the third reserved resource belongs;

[0087] re-selecting all periodic resources included in the first sidelink process;

[0088] prohibiting reserving the third reserved resource in the first reserved resource;

[0089] releasing the first sidelink process;

[0090] wherein the first sidelink process is a sidelink process to which the third reserved resource belongs.

[0091] In this implementation, the third reserved resource is preempted, and the terminal can avoid the transmission collision / interference problem by performing the first operation, thereby improving the reliability of transmission.

[0092] In a case of re-selecting a periodic resource to which the third reserved resource belongs and re-selecting all periodic resources included in the first sidelink process, the terminal performs resource re-selection to perform TB transmission on the re-selected resource, thereby avoiding the transmission collision / interference problem and improving the reliability of transmission.

[0093] In a case of prohibiting reserving the third reserved resource in the first reserved resource, a resource reservation period field can be set to 0, so that the third reserved resource is not reserved in the first reserved resource, thereby avoiding the transmission collision / interference problem and improving the reliability of transmission.

[0094] In a case of releasing the first sidelink process, since the first sidelink process is released, the terminal does not perform the first sidelink process using the third reserved resource, thereby avoiding the transmission collision / interference problem and improving the reliability of transmission.

[0095] In an implementation, after the re-evaluation of the target resource at the first time, the method further comprises:

[0096] In a case where the evaluation result of the re-evaluation indicates that the first reserved resource needs to be re-selected, a second operation is performed, and the second operation comprises any one of the following:

[0097] releasing the first reserved resource;

[0098] releasing a sidelink process to which the first reserved resource belongs.

[0099] In the embodiment, the first reserved resource is preempted, and the terminal can avoid the transmission collision / interference problem by performing the second operation, thereby improving the reliability of the transmission.

[0100] In the scenario of releasing the first reserved resource, the terminal will not perform TB transmission on the first reserved resource, thereby avoiding the transmission collision / interference problem and improving the reliability of the transmission.

[0101] In the scenario of releasing a sidelink process to which the first reserved resource belongs, the terminal will not perform the first sidelink process using the first reserved resource, thereby avoiding the transmission collision / interference problem and improving the reliability of the transmission.

[0102] Embodiment three, optionally, after the re-evaluation of the target resource at the first time, the method further comprises:

[0103] In the case where the evaluation result of the re-evaluation is that the target resource needs to be reselected, performing resource reselection to obtain a fourth reserved resource;

[0104] According to a first rule, it is determined whether to periodically reserve the fourth reserved resource, the first rule comprising at least one of the following:

[0105] 1) the terminal decides whether to periodically reserve the reselected resource;

[0106] 2) according to a second condition, it is determined whether to periodically reserve the reselected resource, wherein in the case where the second condition is met, the reselected resource is periodically reserved, and the second condition being met comprises at least one of the following: the number of transmission resources in a resource period is less than or equal to a second threshold, the second threshold being the maximum number of resources allowed in a resource period or the maximum number of times a TB is allowed to be transmitted; the channel busy ratio (CBR) is less than a third threshold, the third threshold being agreed by a protocol or configured by a control node or preconfigured by the terminal. Specifically, the number of transmission resources in the one resource period can be the number of transmission resources in the next resource period.

[0107] Optionally, the maximum number of resources allowed in the resource period, and the maximum number of times a TB is allowed to be transmitted can be limited per resource pool (pool) or per bandwidth part (BWP), i.e., the maximum number of resources allowed in the resource period, and the maximum number of times a TB is allowed to be transmitted can be the maximum number of resources allowed in the resource period, and the maximum number of times a TB is allowed to be transmitted per pool or BWP.

[0108] In the embodiment, the target resource is preempted, and the terminal performs resource reselection to obtain the fourth reserved resource. The target resource in the embodiment can include one or more of the first reserved resource, the second reserved resource, and the third reserved resource.

[0109] In the embodiment, after obtaining the reselected resource, i.e., the fourth reserved resource, the terminal can determine whether to periodically reserve the reselected resource according to a first rule.

[0110] In the case where the first rule includes 1), the terminal can autonomously determine whether to periodically reserve the reselected resource. If the terminal determines to periodically reserve the reselected resource, i.e., to allow periodic reservation, the terminal can periodically reserve the fourth reserved resource, otherwise, the terminal does not periodically reserve the fourth reserved resource.

[0111] In the case where the first rule includes 2), if the second condition is met, the terminal can periodically reserve the fourth reserved resource, otherwise, the terminal does not periodically reserve the fourth reserved resource.

[0112] In implementation, if the number of transmission resources in a resource period is less than or equal to a second threshold, the terminal can periodically reserve the fourth reserved resource, otherwise, the terminal does not periodically reserve the fourth reserved resource. If the CBR is less than a third threshold, the terminal can periodically reserve the fourth reserved resource, otherwise, the terminal does not periodically reserve the fourth reserved resource.

[0113] It should be noted that in some implementations, if the number of transmission resources in a resource period is less than or equal to a second threshold, or the CBR is less than a third threshold, the terminal can periodically reserve the fourth reserved resource.

[0114] In the above manner, after performing resource reselection, the terminal can periodically reserve the reselected resource, or can not periodically reserve the reselected resource, thereby improving the flexibility of resource reselection.

[0115] It should be noted that the various optional embodiments introduced in the embodiments of the present application can be combined with each other to be implemented, or can be implemented alone, and the embodiments of the present application do not limit this.

[0116] For the convenience of understanding, the following illustrates the scene 1 and scene 2 examples:

[0117] Scene 1: The UE judges whether the reserved resource of the next resource period is occupied (i.e. re-evaluates the reserved resource of the next resource period) in the previous resource period, as shown in FIG. 2a.

[0118] Scene two: when the reserved resource of a certain resource period has no corresponding TB transmission, the reserved resource is re-evaluated, as shown in FIG. 2b.

[0119] Scheme one: this scheme is for scene 1, which explains how to re-evaluate the periodic reserved resource.

[0120] 1) For a certain TB transmission, the transmission resource (PSCCH / PSSCH resource) corresponding to time m needs to be evaluated at'm-T3' time (after evaluation, it can be reselected), and the resource reserved at m time also needs to be evaluated (after evaluation, it can be reselected). The reserved resource includes at least one of the following:

[0121] Only evaluate the non-periodic reserved resource;

[0122] Evaluate the non-periodic and periodic reserved resources.

[0123] In addition, whether to evaluate the periodic reserved resource can depend on: the reservation period is less than a certain threshold, and the threshold can be at least defined / configured / preconfigured by the control node.

[0124] 2) For judging the periodic reserved resource for resource selection evaluation (i.e. judging whether the resource of the subsequent period is occupied after the current period).

[0125] The assumption of the TB transmitted by the periodic reserved resource is:

[0126] 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 of the TB mapped on the PSSCH / PSCCH, the PDB characteristics of the TB, etc.

[0127] The characteristics (or part of the characteristics) of the TB are the characteristics agreed / configured / preconfigured by the protocol, such as the priority of the TB mapped on the PSSCH / PSCCH being the maximum value / minimum value / (pre)configured value, and the PDB characteristics of the TB being a fixed value(pre)configured value.

[0128] 3) If it is judged that the periodically reserved resource needs resource reselection, at least one of the following behaviors is performed

[0129] reselect the corresponding resource of the current period;

[0130] the current period cannot reserve the resource that needs resource reselection (i.e., the periodic reservation field of SCI is 0);

[0131] release the SL process that needs resource reselection.

[0132] Solution two: This solution is for scenario 2, and explains how to reevaluate the periodically reserved resource.

[0133] 1) For the transmission resource (PSCCH / PSSCH resource) located at time m, the condition for resource selection evaluation at time'm-T3' (or, the condition for reselection after evaluation):

[0134] There is TB transmission (i.e., TB arrival is not later than time m-T3) not later than time'm-T3'.

[0135] 2) If there is no TB transmission on the current reserved resource, the UE also performs resource selection evaluation.

[0136] The assumption of the transmission TB is:

[0137] The characteristics (or part of the characteristics) of the TB are the same as the characteristics (or part of the characteristics) of the TB of the previous transmission, such as the priority of the TB mapping on PSSCH / PSCCH, the PDB characteristics of the TB, etc.

[0138] The characteristics (or part of the characteristics) of the TB are the same as the characteristics (or part of the characteristics) of the TB of the previous transmission on the SL process, such as the priority of the TB mapping on PSSCH / PSCCH, the PDB characteristics of the TB, etc.

[0139] The characteristics (or part of the characteristics) of the TB are the characteristics agreed / configured / pre-configured by the protocol, such as the priority of the TB mapping on PSSCH / PSCCH being the maximum value / minimum value / (pre)configured value, the PDB characteristics of the TB being a fixed value (pre)configured value

[0140] 3) If it is judged that the periodically reserved resource needs resource reselection

[0141] release the current resource that needs reselection;

[0142] release the SL process that needs resource reselection.

[0143] Scheme three: this scheme illustrates whether the reselected resource can be periodically reserved to solve the problem of over-reservation of resources.
