Description

[0001] This application is a divisional application of the invention patent application filed on December 21, 2020, with application number 202080004230.9 and title "Method, Apparatus and Storage Medium for Determining Auxiliary Resource Sets". Technical Field

[0002] This disclosure relates to the field of communication technology, and in particular to a method, apparatus and storage medium for determining auxiliary resource sets. Background Technology

[0003] Since Long Term Evolution (LTE), the Third Generation Partnership (3GPP) has been developing the Sidelink (SL, also known as a direct link) standard for end-to-end direct communication. In July 2020, the first standard for New Radio (NR) Sidelink was finalized in Release 16 (hereinafter referred to as Rel-16), with NR Sidelink solutions primarily intended for Vehicle to Everything (V2X) and public safety. Due to time constraints, Release 16 did not fully support service requirements and operational scenarios for V2X and public safety, and Service and System Aspects (SA) received some enhancements in Release 17 NR Sidelink, such as architectural and system enhancements to support advanced V2X services within 3GPP. Furthermore, the SA working group is exploring other commercial use cases related to NR Sidelink, such as interactive services for network control, enhanced energy-efficient relays, wide coverage, and audiovisual service production. Therefore, at the 86th 3GPP plenary meeting, in the Release 17 project proposal, the enhancement of NRSidelink was included as a work item, with the aim of improving the reliability of Sidelink transmission and reducing latency.

[0004] In the NR Sidelink enhancement, user equipment A (UE A) for direct communication can send an auxiliary resource set to UE B (UE B) using resource selection mode 2, which UE B then considers when selecting resources for its own data transmission. However, in related technologies, the large number of resources in the perceived auxiliary resource set leads to significant signaling overhead for UE A when sending the auxiliary resource set.

[0075] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0076] The auxiliary resource set determination method provided in this disclosure can be applied to... Figure 1 The direct-connect communication system shown. (See attached image) Figure 1As shown, in a scenario where direct communication occurs between directly connected communication devices, the network device configures various transmission parameters for data transmission for directly connected communication device 1. Directly connected communication devices 1, 2, and 3 communicate directly. Obstacles may exist between directly connected communication devices 2 and 3. The communication link between the network device and the directly connected communication devices is an uplink / downlink, while the link between directly connected communication devices is a sidelink.

[0077] In this disclosure, the communication scenario of direct communication between directly connected communication devices can be a Vehicle to Everything (V2X) service scenario. Here, V represents the on-board device, and X represents any object interacting with the on-board device. Currently, X mainly includes on-board devices, handheld devices, roadside infrastructure, and networks. V2X interaction modes include: vehicle to vehicle (V2V), vehicle to infrastructure (V2I), vehicle to handheld devices (V2P), and vehicle to network (V2N).

[0078] With the development of next-generation 5G mobile communication technology, 3GPP Rel-16 utilizes 5G NR technology to support new V2X communication services and scenarios, such as vehicle platooning, extended sensors, advanced driving, and remote driving. Overall, 5G V2X sidelink offers higher communication rates, lower latency, and more reliable communication quality.

[0079] The communication scenario of direct communication between directly connected communication devices can also be a device-to-device (D2D) communication scenario. In the embodiments of this disclosure, the directly connected communication devices performing direct communication can include various handheld devices, vehicle-mounted devices, wearable devices, computing devices, or other processing devices connected to a wireless modem, as well as various forms of user equipment (UE), mobile station (MS), terminal, terminal equipment, etc. For ease of description, the embodiments of this disclosure will use user equipment as an example for the following description.

[0080] Among these enhancements, NR Sidelink can improve transmission reliability and reduce latency. Regarding the enhancement of Mode 2 resource allocation, the 3GPP working group concluded that a method for assisted resource selection between user equipments (UEs) needs to be studied. This method defines two UEs, for example, UE A is an auxiliary UE of UE B, and UE B is the UE that needs to select resources for its own data transmission. UE A determines a resource set and sends it to UE B via Mode 2. When selecting resources, UE B considers the auxiliary resource set sent by UE A; that is, UE B uses an auxiliary resource set assistance mechanism for resource selection. UE B can then send data to UE A and / or other UEs.

[0081] However, when user equipment A sends the auxiliary resource set, if user equipment A sends all the candidate auxiliary resource sets it senses to user equipment B via control signaling, and the number of resources in the weakly sensed candidate auxiliary resource set is large, it will cause a large overhead of control signaling.

[0082] To reduce the overhead of control signaling, embodiments of this disclosure provide an auxiliary resource set determination method. This method proposes that user equipment A selects a subset of time-frequency resources from a perceived candidate auxiliary resource set as an auxiliary resource subset, and reports this auxiliary resource subset to user equipment B. This reduces the number of resources reported by user equipment A to user equipment B, thereby assisting user equipment B in resource selection.

[0083] For ease of description in this embodiment, the device that provides auxiliary resources is referred to as the first device, and the device that uses the auxiliary resource set assistance mechanism to select resources is referred to as the second device.

[0084] Figure 2 This is a flowchart illustrating an auxiliary resource set determination method according to an exemplary embodiment, such as... Figure 2 As shown, the auxiliary resource set determination method is used in the first device and includes the following steps.

[0085] In step S11, a subset of auxiliary resources is determined.

[0086] The auxiliary resource subset includes a portion of the time-frequency resources in the candidate auxiliary resource set sensed by the first device.

[0087] The auxiliary resource set determination method provided in this embodiment determines a subset of time-frequency resources in the candidate auxiliary resource set sensed by the first device as an auxiliary resource subset, which can reduce the number of resources reported to the second device and thus reduce signaling overhead.

[0088] Figure 3 This is a flowchart illustrating an auxiliary resource set determination method according to an exemplary embodiment, such as... Figure 3 As shown, the auxiliary resource set determination method is used in the first device and includes the following steps.

[0089] In step S21, a subset of auxiliary resources is determined.

[0090] The auxiliary resource subset includes a portion of the time-frequency resources in the candidate auxiliary resource set sensed by the first device.

[0091] In step S22, a subset of auxiliary resources is sent.

[0092] The auxiliary resource set determination method provided in this embodiment determines a subset of time-frequency resources in the candidate auxiliary resource set sensed by the first device as an auxiliary resource subset, and sends the auxiliary resource subset to the second user equipment. This can reduce the number of resources reported to the second device, thereby reducing signaling overhead.

[0093] In this embodiment of the disclosure, the second device can receive an auxiliary resource subset sent by the first device, and when making resource selection, it can consider the auxiliary resource subset sent by the first device and use the auxiliary resource set assistance mechanism to make resource selection.

[0094] Figure 4 This is a flowchart illustrating an auxiliary resource set determination method according to an exemplary embodiment, such as... Figure 4 As shown, the auxiliary resource set determination method is used in the second device and includes the following steps.

[0095] In step S31, a subset of auxiliary resources is received.

[0096] The auxiliary resource subset includes a portion of the time-frequency resources in the candidate auxiliary resource set sensed by the first device.

[0097] In this embodiment of the disclosure, the second device receives a subset of auxiliary resources, which includes a portion of time and frequency resources in the candidate auxiliary resource set sensed by the first device, thereby saving the signaling overhead of the second device in receiving the auxiliary resource set.

[0098] The following description of the embodiments disclosed herein will focus on the auxiliary resource subset sent by the first device and / or the auxiliary resource subset received by the second device.

[0099] In one embodiment, the auxiliary resource set determination method provided in this disclosure may include a resource table (ist).

[0100] In this embodiment of the disclosure, the resource table, which is a subset of auxiliary resources, has a table length, hereinafter referred to as the first table length.

[0101] In the auxiliary resource set determination method provided in this embodiment, the first device can report the auxiliary resource subset using a resource table, and report a resource table with a first table length. Assume the first table length is L. The first device reports the auxiliary resource subset using a resource table, and reports the auxiliary resource subset with a table length of L.

[0102] In the auxiliary resource set determination method provided in this embodiment, the second device can receive a resource table with a table length of L and determine an auxiliary resource subset based on the resource table.

[0103] In the auxiliary resource set determination method provided in this embodiment, the first table length of the auxiliary resource subset in the form of a resource table can be a fixed table length. For example, the first table length is a pre-configured fixed table length.

[0104] In this embodiment, when the first device determines the subset of auxiliary resources, it can do so based on the resource selection window of the second device. Specifically, the second device carries its resource selection window in the auxiliary request sent to the first device via control signaling. The first device numbers the resources in the detected candidate auxiliary resource set that fall within the resource selection window of the second device to form a resource table. The method of numbering the resource table is pre-agreed upon by the first and second devices. In other words, both the first and second devices can determine the resource table and its numbering. The resource table numbering is performed in the frequency domain using frequency domain units and in the time domain using time domain units. Frequency domain units can be channels, subchannels, subbands, bands, etc. Time domain units can be slots, radio frames, subframes, mini-slots, symbols, transmission time intervals (TTI), etc. In the embodiments of this disclosure, the resource table numbering is performed in the frequency domain by sub-channel and in the time domain by time slot, but this disclosure is not limited to this.

[0105] In the auxiliary resource set determination method provided in this disclosure, on one hand, the auxiliary resource subset can be a time-frequency resource that conforms to the length of a first table, randomly selected from the candidate auxiliary resource set. That is, in this disclosure embodiment, the first device can use a time-frequency resource that conforms to the length of a first table, randomly selected from the candidate auxiliary resource set, as the auxiliary resource subset.

[0106] Figure 5This illustration shows a schematic diagram of a first device randomly selecting time-frequency resources conforming to a first table length from a candidate auxiliary resource set sensed by the first device, in an exemplary embodiment of this disclosure. (See also...) Figure 5 As shown, the candidate auxiliary resource set sensed by the first device is numbered in the resource table at the subchannel level in the frequency domain and at the slot level in the time domain. (See reference...) Figure 5 In this context, the time-frequency resources in the resource table represent a set of candidate auxiliary resources perceived by the first device. Assuming the first table is pre-configured to have a length L = 8, the first device randomly reports a resource table with a length of 8 from the candidate auxiliary resource set. For example, it can randomly select time-frequency resources numbered {2, 4, 5, 7, 8, 10, 12, 20} as a subset of auxiliary resources and send it to the second device.

[0107] In the auxiliary resource set determination method provided in this disclosure, on the other hand, the auxiliary resource subset may be time-frequency resources that conform to the length of a first table, selected from the candidate auxiliary resource set based on the Reference Signal Receiving Power (RSRP). That is, the first device selects time-frequency resources that conform to the length of the first table from the sensed candidate auxiliary resource set based on RSRP, as the auxiliary resource subset.

[0108] In one embodiment, the first device selects time and frequency resources that conform to the length of a first table from the candidate auxiliary resource set in ascending order of the reference signal received power value.

[0109] Figure 6 This illustration shows a schematic diagram of a first device selecting time-frequency resources conforming to a first table length as a subset of auxiliary resources from a sensed candidate auxiliary resource set based on RSRP in an exemplary embodiment of this disclosure. See also... Figure 6 As shown, during the time period Tproc,0 of the candidate auxiliary resource set sensed by the first device, the RSRP values ​​of the measured Physical Sidelink Control Channel (PSCCH) demodulation reference signals (DMRS) on the monitored resources are sorted from smallest to largest, with priority given to resources with lower RSRP values. According to the table length L of the pre-configured resource table, the first device selects resources with a table length of 8 and low RSRP values, such as {5, 7, 8, 10, 12, 20, 22, 25}, as these time-frequency resources cause the least interference when used by the second device for data transmission. The time-frequency resources numbered {5, 7, 8, 10, 12, 20, 22, 25} are selected as a subset of auxiliary resources and sent to the second device.

[0110] The auxiliary resource set determination method disclosed herein includes a pre-configured resource table with a first table length L, and an auxiliary resource set of length L belonging to the candidate auxiliary resource set sensed by the first device, which is used as an auxiliary resource subset.

[0111] In the auxiliary resource set determination method provided in this embodiment, the first table length of the resource table can be either a pre-configured fixed table length or a flexibly dynamically changing table length.

[0112] In one embodiment, the length of the first table in this disclosure is determined based on the minimum ratio satisfied by the ratio of resources in the candidate auxiliary resource set to resources in the resource selection window of the second device.

[0113] In this embodiment, for ease of description, the minimum ratio between the resources in the candidate auxiliary resource set and the resources in the resource selection window of the second device is referred to as the first ratio. Based on communication protocol R16, to ensure the randomness of resource selection, the ratio between the resources in the candidate auxiliary resource set and the resources in the resource selection window determined in step 1 of resource awareness needs to meet the requirement of ≥X% (the first ratio). Here, X% is specified according to the protocol, thus ensuring more resources and satisfying the randomness of resource selection.

[0114] In one embodiment, the candidate auxiliary resource set determination method provided in this disclosure may set a proportional offset value (Y%) relative to a first proportion. The length of a first table is determined based on the proportional offset value relative to the first proportion.

[0115] In one example, in this embodiment of the present disclosure, the length of the first table can be determined based on the number of resources in the resource selection window of the second device, a first ratio, and a ratio offset value relative to the first ratio. For example, the first device determines the length of the first table by L = S * (X% + Y%). Where S is the number of resources in the UEB resource selection window, X% is the first ratio, Y% is the ratio offset value relative to the first ratio, and L is the length of the first table.

[0116] In this embodiment, the proportional offset value Y% relative to the first ratio is pre-configured by Radio Resource Control (RRC). The number of resources S in the UEB resource selection window is calculated based on their position within the resource selection window. The first device obtains the position of the resource selection window through an auxiliary request from the second device.

[0117] In this embodiment, the first device calculates the first table length of the resource table and notifies the second device of the determined resource table via control signaling. The first device randomly selects and reports a subset of auxiliary resources with a resource table length of L from the perceived candidate auxiliary resource set to the second device. The first table length is determined based on the number of resources in the resource selection window of the second device, a first ratio, and a ratio offset value relative to the first ratio, so that the reported first table length changes with the number of resources in the candidate auxiliary resource set perceived by the first device, making the scheme more flexible.

[0118] In one feasible example, assume the first proportion X% is 40%. When the first device performs candidate auxiliary resource set perception, the final determined resource proportion needs to satisfy greater than X%. For example, in this embodiment of the disclosure, the proportion of the candidate auxiliary resource set is set to 75%. Figure 7 A schematic diagram of a candidate auxiliary resource set identified in a conventional technique is shown. (See also...) Figure 7 As shown, the first device needs to select 21 time and frequency resources from 28 time and frequency resources as auxiliary resources and send them to the second device.

[0119] Figure 8 This illustration shows a schematic diagram of an exemplary embodiment of the present disclosure in which a first device determines the length of a first table and performs auxiliary resource set determination based on the number of resources in the resource selection window of a second device, a first ratio, and a ratio offset value relative to the first ratio. (See also...) Figure 8 As shown in this embodiment, when the first device determines the subset of auxiliary resources, the selected resources need to satisfy a first ratio of X% and a ratio of (X% + Y%). Assuming the first ratio of X% is 40% and (X% + Y%) is 50%, the first device can select 12 time-frequency resources from 28 time-frequency resources as auxiliary resources and send them to the second device.

[0120] Specifically, the first device can select 12 time and frequency resources from 28 time and frequency resources as auxiliary resources to send to the second device. Compared with selecting 21 time and frequency resources from 28 time and frequency resources as auxiliary resources to send to the second device, the number of auxiliary resources reported can be reduced and the signaling overhead can be reduced.

[0121] In the auxiliary resource determination method provided in this embodiment, the first device can determine an auxiliary resource subset based on the resource selection window of the second device.

[0122] In one embodiment, the auxiliary resource subset consists of time-frequency resources with a first timeslot length that are located within the resource selection window of the second device. The first timeslot length is less than the total timeslot length within the resource selection window of the second device.

[0123] In one implementation, the auxiliary resource set is a continuous time-frequency resource with a first time slot length, determined based on a first time. The first time is either the start or end time of the resource selection window of the second device.

[0124] Figure 9 This illustration shows a schematic diagram of a first device determining an auxiliary resource subset based on a resource selection window of a second device in an exemplary embodiment of this disclosure. See also... Figure 9 As shown, user equipment A selects time frequency resources of slots with a fixed length of L (L≤ the number of slots in the resource selection window of user equipment B, and the value of L is pre-configured by RRC) before the end of the resource selection window of user equipment B as an auxiliary resource subset and reports it to user equipment B.

[0125] Specifically, the position of time slot n+T2 at the end of the resource selection window of user equipment B is notified to user equipment A by user equipment B in the auxiliary request via control signaling. The value of the time slot length L is pre-configured via RRC signaling.

[0126] It is understood that in this embodiment of the disclosure, user equipment A is aware of the resource selection window [n+T1, n+T2] of user equipment B. Specifically, user equipment A senses time-frequency resources within user equipment B's resource selection window, but selects time-frequency resources with a reporting time slot length of L as an auxiliary resource subset and reports them to user equipment B. That is, it reports a subset of time-frequency resources located within user equipment B's resource selection window.
