Description

Side link resource selection processing method, side link resource selection processing device, communication equipment and readable storage medium

Technical Field

The application belongs to the technical field of communication, and particularly relates to a side link resource selection processing method, a side link resource selection processing device, communication equipment and a readable storage medium.

Background

With the development of communication technology, sidelink (SL) transmission is widely used. The present side link resource can be selected by the terminal independently or can be allocated by the network side equipment. For the autonomous selection mode, after the triggering of the resource selection, the transmitting end (TX UE) generally determines a resource selection window first, determines an alternative resource set based on the resource selection window, and then performs resource exclusion on the alternative resource to obtain a target alternative resource set. The final target candidate resource set is obtained because resource exclusion is currently only performed based on reference signal received power (Reference Signal Received Power, RSRP) and non-monitored slots (non-monitored slots) measured on resources within the resource selection window. This results in that the side link resources selected randomly for transmission in the target candidate resource set are prone to situations where transmission is not possible (e.g. collision with other resources occurs), and thus the reliability of SL transmission is low in the prior art.

Detailed Description

Technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application are within the scope of the protection of the present application.

It is to be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or otherwise described herein, and that the terms "first" and "second" are generally intended to be used in a generic sense and not to limit the number of objects, for example, the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/" generally means a relationship in which the associated object is an "or" before and after.

It is noted that the techniques described in embodiments of the present application are not limited to long term evolution (Long Term Evolution, LTE)/LTE evolution (LTE-Advanced, LTE-a) systems, but may also be used in other wireless communication systems, such as code division multiple access (Code Division Multiple Access, CDMA) Time division multiple access (Time Division Multiple Access, TDMA), frequency division multiple access (Frequency Division Multiple Access, FDMA), orthogonal frequency division multiple access (Orthogonal Frequency Division Multiple Access, OFDMA), single-carrier frequency division multiple access (Single-carrier Frequency Division Multiple Access, SC-FDMA), and other systems. The terms "system" and "network" in embodiments of the present application are often used interchangeably, and the techniques described may be used for both the above-mentioned systems and radio technologies, as well as other systems and radio technologies. The following description describes a New air interface (NR) system for purposes of example and uses NR terminology in much of the description that follows, but these techniques are also applicable to applications other than NR system applications, such as generation 6 (6) ^th Generation, 6G) communication system.

In order to facilitate understanding of the embodiments of the present application, the following technical points are first described:

1. New air interface sidelink (NR SL) resource selection.

There are two ways of NR SL resource allocation, 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, a sidelink resource of the UE for data transmission is determined by the base station and is notified to a transmitting end (TX UE) through 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 (sending) result, and then randomly selects resources for transmission from the resource set.

For mode 2, the specific operation is as follows:

step 1: when the TX UE performs resource selection, the medium access layer (Medium Access Control, MAC) layer provides the physical layer with a resource selection related parameter, where the parameter includes a resource selection trigger time-slot n (slot_n), a remaining packet delay budget (remaining PDB), a priority (priority), a number of sub-channels (number of sub-channels) and a resource reservation interval (resource reservation interval), and after the physical layer acquires the resource selection related parameter, the physical layer determines a resource selection window first, where a lower boundary of the resource selection window is at a T1 time after slot_n, and an upper boundary of the resource selection window is at a T2 time of slot_n, where T2 is a value selected by the UE implementation in a remaining PDB transmitted by its TB, and T2 is not earlier than T1.

Step 2: before the UE selects a resource, it needs to determine an alternative set of resources (candidate resource set) for the resource selection, and compares the reference signal received power (Reference Signal Received Power, RSRP) measured on the resources in the resource selection window with a corresponding RSRP threshold (RSRP threshold), and if the RSRP is higher than the RSRP threshold, the resource is excluded from being included in the alternative set of resources. 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 (for example, 3 dB), and then the resource exclusion operation is performed until the ratio of the resources not less than x% can be selected.

Step 3: after the alternative resource set is determined, the UE randomly selects transmission resources in the alternative resource set. In addition, the UE may reserve transmission resources for the next transmission at this time of transmission.

The above step 2 can be described in the related art as 7 sub-steps as follows:

step 2-1: the UE determines an alternative resource based on the resource selection window, and the total number of alternative resources is denoted as m_total.

Step 2-2: the UE obtains a sensing result, e.g. reservation information in a physical secondary link control channel (Physical SideLink Control Channel, PSCCH), in a listening window (sensing window), reservation resource associated RSRP measurement values.

Step 2-3: the UE determines an initial RSRP threshold value (initial RSRP threshold).

Step 2-4: the UE initializes a set of alternative resources, including all the alternative resources determined in step 2-1 (which may also be referred to as all the alternative resources in the resource selection window).

Step 2-5: the UE performs resource exclusion based on a non-monitored slot, and excludes resources meeting a first preset condition from the alternative resource set.

Step 2-5a: if the number of the remaining resources in the candidate resource set is less than x% m_total after the resource exclusion is performed based on step 2-5, the candidate resource set is restored to the initial candidate resource set determined in step 2-4.

Step 2-6: and the UE performs resource exclusion based on the comparison of the RSRP measured value and the RSRP threshold value, and excludes the resources meeting the second preset condition from the alternative resource set.

Step 2-7: if the number of the remaining resources in the alternative resource set is less than x% m_total after the resource exclusion is performed based on the step 2-6, the RSRP threshold is raised by 3dB, and the process continues to return to the step 2-4.

2. NR sidelink resource selection enhancement (enhancement) scheme.

Enhancement schemes are divided into scheme 1 (scheme 1) and scheme 2 (scheme 2).

For scheme 1, UE-A determines "transmission resources (i.e., preferred resource) that favor UE-B's use" and recommends this set of resources to UE-B, which may consider the set of resources recommended by UE-A in making the resource selection. The UE-A determines preferred resource based on at least Condition 1-A-1 (Condition 1-A-1) and Condition 1-A-2 (Condition 1-A-2) as follows. In particular for condition 1-a-2, UE-a selects preferred resource from the candidate resources, and "target slots" are excluded after step 6 in the process of determining the candidate resource set by UE-a.

A "target slot" may be understood as a SL reception (time) resource that the UE-a does not expect to receive, including at least one of the following (time) resources:

(1) UE-a does not expect received SL (time) resources due to half duplex limitations.

(2) UE-a does not expect SL (time) resources for SL reception due to concurrency constraints.

(3) SL transmission resources (/ time resources) for UE-A.

(4) When the UE-B sends PSSCH to the UE-A, PSFCH transmission and reception conflict (time) resource of the UE-A is caused, namely half duplex conflict.

(5) When the UE-B transmits the PSSCH to the UE-a, a physical sidelink feedback channel (Physical SideLink Feedback Channel, PSSCH) of the UE-a is caused to transmit and receive conflicting (time) resources, i.e., half duplex collisions.

(6) When the UE-B transmits PSSCH to the UE-A, the PSSCH reception and the UL transmission of the UE-A collide with (time) resources.

(7) When the UE-B transmits PSSCH to the UE-A, the (time) resource causing the PSFCH transmission and UL transmission of the UE-A collide, i.e. concurrency collision.

(8) When the UE-B transmits PSSCH to the UE-A, it causes multiple PSFCH transmission collisions (time) resources of the UE-A, i.e. concurrency collisions.

For condition 1-a-1 in scheme 1, the related art specifies that the preferred set of resources for the transmission of UE-B is in the form of candidate single-slot resources. For condition 1-a-2 in scheme 1, the preferred set of resources for ue-B transmission is one form of candidate single-slot resources specified in the related art:

after step 2-6, UE-a excludes candidate single-slot candidate operations belonging to "slots for which SL reception is not expected from UE-B due to half-duplex when UE-a is the receiving end of UE-B".

For another scheme of scheme 1, UE-A determines "transmission resources not prone to be used by UE-B (i.e., non-preferred resource)", and recommends this set of resources to UE-B, which may consider the set of resources recommended by UE-A in making the resource selection. The UE-A determines non-preferred resource based on at least Condition1-B-1 (Condition 1-B-1) and Condition1-B-1 (Condition 1-B-2) as follows. Especially for condition1-B-1, UE-a determines non-preferred resource based on the RSRP measurement value associated with reserved resource of the other UEs compared to the (pre) configured RSRP threshold.

For condition 1-B-1 of scheme 1, the following two options are supported:

-option 1: the reserved resources of the other UE identified by UE-a, whose RSRP measurement value is larger than a (pre) configured RSRP threshold value determined by at least the priority value indicated by the UE's sidelink control information (Sidelink Control Information, SCI);

-option 2: the reserved resources of the other UEs identified by UE-a have RSRP measurement values smaller than the (pre) configured RSRP threshold value, which is determined at least by the priority value indicated by the SCI of the UE when UE-a is the destination of the Transport Block (TB) sent by the UE.

For scheme 1 of the non-favored resource set, the following conditions are supported:

-condition 1-B-2:

resources (e.g., time slots) where SL reception from UE-B is not expected due to half-duplex operation when UE-a is the intended receiving end of UE-B.

For scheme 2, UE-A determines that a collision occurs with the transmission resources of UE-B and indicates the collision to UE-B. When the UE-A determines that resources conflict, the UE-A is based on at least Condition2-A-1 and Condition 2-A-2 as follows. Especially for Condition2-a-1, if UE-a as RX UE decides that its TX UE's transmission resources overlap with the transmission resources of the other UE and that the RSRP measurement value associated with the other UE transmission resources is larger than the (pre) configured RSRP threshold (or that the difference between the RSRP measurement value associated with the other UE transmission resources and the RSRP measurement value associated with the TX UE's transmission resources is larger than the preset RSRP threshold), UE-a decides that the transmission resources collide.

The resource pool level (pre) configuration may enable one of the following options:

(1) Option 1:

for condition 2-A-1 of scheme 2, the following additional criteria are supported to determine the resources where the expected/potential resource conflict occurs:

(a) For the case where UE-a is the destination UE of the TBs transmitted by UE-B:

the resources overlap in time and frequency with reserved resources of other UEs whose RSRP measurement is greater than the RSRP threshold value, according to the priorities included in SCI:

the sender priority (prio_tx) and the receiver priority (prio_rx) are priorities indicated in SCI, and overlap reservation is made for UE-B and other UEs, respectively.

(b) For the case where UE-a is the destination UE of a TB transmitted by another UE:

when the RSRP measurement of the reserved resources of UE-B is greater than the RSRP threshold value according to the priority included in SCI, the resources overlap fully/partially with the reserved resources of other UEs in time and frequency:

the sender priority and the receiver priority are priorities indicated in SCI, and overlap reservation is performed for other UE and UE-B, respectively.

(2) Option 4:

for condition 2-A-1 of scheme 2, the following additional rules are supported to determine the resources where the expected/potential resource conflict occurs.

In comparison to the RSRP measurement of reserved resources of UE-B, the resources overlap in time and frequency with reserved resources of other UEs whose RSRP measurement is greater than the (pre) configured RSRP threshold value.

when the RSRP measurement of the reserved resources of the UE-B is greater than the (pre) configured RSRP threshold value compared to the RSRP measurement of the resources, the resources overlap fully/partially in time and frequency with the reserved resources of other UEs.

The support of option 4 depends on the UE's capabilities, among other things.

In scheme 2, inter-UE coordination information is determined in support of at least the following:

among the resources indicated by the SCI of UE-B, UE-a considers that an expected/potential resource conflict occurs on resources that satisfy at least one of the following conditions:

condition 2-a-2: resources (e.g., time slots) where SL reception from UE-B is not expected due to half-duplex operation when UE-a is the intended receiver of UE-B.

Problem 1: for scheme 1, when UE-A determines a transmission resource (preferred resource) that is intended for UE-B or a transmission resource (non-preferred resource) that is not intended for UE-B based on a candidate single slot set of resources (candidate single-slot resource set), a "target slot" may be excluded after step 2-6 identified by candidate single-slot resource set based on Condition 1-A-2 or Condition 1-B-2. However, when the number of "target slots" is too large, at least the following problems are caused:

1) The number of remaining alternative resources is always less than x% m_total, resulting in a dead loop of steps 2-4-2-7;

2) The interference strength of the remaining resources in the alternative resource set is large, and the transmission reliability is affected.

In addition, if UE-A does not perform the sending, UE-A will not perform steps 2-6.

Problem 2: for scheme 1, UE-A determines non-preferred resource, based on Condition 1-B-1, UE-A will determine non-preferred resource based on a comparison of the RSRP measurement and the RSRP threshold. The determination of non-preferred resource should reflect at least the resource interference strength that UE-a can tolerate, and the setting of RSRP threshold requires a corresponding flexibility since the system expects UE-a to tolerate interference strength that is affected by how busy the system resources are.

Problem 3: for scheme 2, when the UE-A decides that resources collide, based on Condition 2-A-1, the UE-A will determine non-preferred resource based on a comparison of the RSRP measurement (or the difference of the RSRP measurement) and the RSRP threshold. The determination of resource conflict should be based at least on the resource interference strength that UE-a can tolerate, and the setting of RSRP threshold requires corresponding flexibility since the system expects that the interference strength that UE-a tolerates is affected by the busyness of the system resources.

Embodiment one: condition 1-A-2/Condition 1-B-2

In the case where UE-A does not perform the sending, UE-B directly excludes the "target slot" after determining initial candidate single-slot resource set. In the case of UE-A serving, UE-B excludes the "target slot" after step 2-6.

Alternative 1: the first information indicates the number/duty cycle of "target slots".

Optionally, the first information indicates a maximum value of the number or a range value of the minimum value of the number of "target slots"; alternatively, the first information indicates a duty ratio value of "target slot"/a maximum value of duty ratio/a minimum value of duty ratio/a range value of number duty ratio.

Optionally, the duty ratio is the duty ratio of the total number of slots of the "target slot" in the initial candidate set/in the resource selection window.

The first information is protocol conventions/configurations/preconfigured/obtained according to convention rules.

Alternative 2: the first information indicates the number/duty cycle of candidate resources that the UE excludes based on the "target slot".

Alternative 2-1: the first information indicates the number/duty cycle of alternative resources that the UE can use for resource exclusion, overlapping the "target slot".

Optionally, the first information indicates a range value of the number value/maximum value/minimum value/number of the number of candidate resources; alternatively, the first information indicates a ratio value/a maximum value of the ratio/a minimum value of the ratio/a range value of the number ratio of the alternative resource.

Optionally, the duty cycle is a duty cycle of a total number of candidate resources of the candidate resources in the initial candidate set/in a resource selection window.

Alternative 2-2: the first information indicates that after candidate resources are excluded based on a "target slot", a reduction in a candidate resource duty cycle of the candidate resource set is less than/equal to y%, the duty cycle being relative to a duty cycle of the candidate resource in the initial candidate set; the UE may exclude as many alternative resources as possible as long as the above condition is satisfied.

For example, y% is protocol contract/configuration/pre-configured/derived from contract rules.

Alternative 2-3: the first information indicates that after candidate resources are excluded based on a 'target slot', the ratio of the candidate resources to the candidate resources before the exclusion is reduced by less than/equal to Y% or the number of the candidate resources is reduced by less than/equal to Y%; the UE may exclude as many alternative resources as possible as long as the above condition is satisfied.

M_total, the UE may further exclude as many candidate resources overlapping with the "target slot" as possible, so long as the number of remaining candidate resources is ensured to be greater than/equal to x%. M_total.

Alternative modes 1-4: after the candidate resources are excluded based on the "target slot", the number of candidate resources in the candidate resource set needs to be greater than/equal to x% m_total.

Alternative 3: the alternative resource occupancy/number in the alternative resource set is reduced, for example by x% in steps 2-7.

Optionally, the offset is protocol contract/configure/preconfigured/derived according to contract rules.

Optionally, the offset is determined based on the number of "target slots". For example, offset is the ratio of the "target slot" to the total number of slots in the initial candidate set.

The preset value is determined, for example, according to the number of (max) preferred resource/non-preferred resource that the UE-a can indicate.

Alternative 4: the cardinality of the alternative resource duty cycle in the alternative resource set is reduced, i.e., m_total in steps 2-7 is reduced.

When the UE performs resource exclusion based on the "target slot", the UE assumes that the duty cycle base is m_total-offset/m_total, and determines whether to complete the alternative resource set determination according to m_total-offset/m_total.

Optionally, the offset/y% is protocol contract/configured/preconfigured/derived according to contract rules. For example, the offset value is equal to the number of alternative resources that overlap with the "target slot".

Alternative 6: if the number of alternative resources overlapping the "target slot" is greater than a preset value (e.g., (1-x%)) m_total, the UE does not exclude alternative resources overlapping the "target slot", at least preventing step 4) -step 7).

Alternative 7: if the number of alternative resources overlapping the "target slots" and the number of resources excluded based on non-monitor slots are greater than a preset value (e.g., (1-x%). M_total), the UE does not exclude alternative resources overlapping the "target slots" and/or resumes resources excluded based on non-monitor slots, at least preventing the dead loop of steps 2-4-2-7.
