[0002] Vehicle-to-Everything (V2X) has been introduced in 5G wireless communication technology. According to the channel structure of V2X communication, the direct link between two user equipments (UEs) is called sidelink (SL). Sidelink is a Long Term Evolution (LTE) feature introduced in 3GPP Release 12, and enables direct communication between proximate UEs with data not needing to go through a base station (BS) or core network.

[0003] It is desirable to increase network throughput, coverage, and robustness, and to reduce latency and power consumption for 5G and / or NR networks. As 5G and NR networks evolve, various aspects need to be researched and developed to perfect 5G / NR technology. SUMMARY

[0004] Some embodiments of the present application provide a method for wireless communication performed by a user equipment (UE). The method includes receiving sensing report configuration information, and the sensing report configuration information includes linkage information between a set of sidelink resources, a sensing result request resource, and a sensing result report resource for the UE; determining whether to transmit a sensing result message based on the sensing report configuration information; and in response to a determination to transmit the sensing result message, transmitting the sensing result message.

[0018] The detailed description of the drawings is intended as a description of the preferred embodiments of the present application and is not intended to represent the only form in which the present application can be practiced. It is understood that the same or equivalent functions can be accomplished by different embodiments that are intended to be encompassed within the spirit and scope of the present application.

[0019] Reference will now be made in detail to some embodiments of the present application, examples of which are illustrated in the accompanying drawings. To facilitate understanding, embodiments are provided under a particular network architecture and new service cases, such as 3GPP 5G, 3GPP LTE Release 8, etc. It is contemplated that all embodiments in the present application are also applicable to similar technical problems as the network architecture and new service cases evolve; and furthermore, the terminology cited in the present application can vary, which should not affect the principles of the present application.

[0020] Figure 1 A schematic diagram illustrating a wireless communication system in accordance with some embodiments of the present application is shown.

[0021] Figure 1 As shown in FIG. 1, the wireless communication system 100 includes at least one user equipment (UE) 101 and at least one base station (BS) 102. In particular, for illustrative purposes, the wireless communication system 100 includes two UEs 101, such as UE 101a and UE 101b, and one BS 102. Although a particular number of UEs 101 and BSs 102 are depicted in FIG. 1, it is contemplated that any number of UEs 101 and BSs 102 can be included in the wireless communication system 100. Figure 1 As shown in FIG. 1, the wireless communication system 100 includes at least one user equipment (UE) 101 and at least one base station (BS) 102. In particular, for illustrative purposes, the wireless communication system 100 includes two UEs 101, such as UE 101a and UE 101b, and one BS 102. Although a particular number of UEs 101 and BSs 102 are depicted in FIG. 1, it is contemplated that any number of UEs 101 and BSs 102 can be included in the wireless communication system 100.

[0022] The UE(s) 101 can include a computing device, such as a desktop computer, a laptop computer, a personal digital assistant (PDA), a tablet computer, a smart television (e.g., a television connected to the Internet), a set-top box, a game console, a security system (including security cameras), a vehicle computer, a network device (e.g., a router, switch, and modem), or the like. According to some embodiments of the present application, the UE(s) 101 can include a portable wireless communication device, a smart phone, a cellular phone, a flip phone, a device with a subscriber identity module, a personal computer, a selective call receiver, or any other device capable of sending and receiving communication signals on a wireless network.

[0023] In some embodiments of the application, the UEs are pedestrian UEs (P-UEs or PUEs) or cyclist UEs. In some embodiments of the application, the UEs 101 include wearable devices, such as smart watches, fitness bands, optical head-mounted displays, or the like. Further, the UE(s) 101 can be referred to as subscriber units, mobiles, mobile stations, users, terminals, mobile terminals, wireless terminals, fixed terminals, subscriber stations, user terminals, or devices, or by other terminology used in the art, to describe any device that uses a wireless communication link to communicate over a wireless channel. The UEs 101 can communicate directly with the BSs 102 via LTE or NR Uu interfaces.

[0024] In some embodiments of the application, each of the UE(s) 101 can be deployed with IoT applications, eMBB applications, and / or URLLC applications. For example, the UE 101a can implement IoT applications and can be named as an IoT UE, while the UE 101b can implement eMBB applications and / or URLLC applications and can be named as an eMBB UE, a URLLC UE, or an eMBB / URLLC UE. It is contemplated that the specific type(s) of applications deployed in the UE(s) 101 can vary and are not limited.

[0025] According to some embodiments of the application, Figure 1 , the UE 101a acts as a Tx UE and the UE 101b acts as an Rx UE. The UE 101a can exchange V2X messages with the UE 101b over a sidelink (e.g., a PC5 interface defined in 3GPP TS 23.303). The UE 101a can transmit information or data to other UE(s) within a V2X communication system through sidelink unicast, sidelink groupcast, or sidelink broadcast. For example, the UE 101a transmits data to the UE 101b in a sidelink unicast session. The UE 101a can transmit data to the UE 101b and other UEs in a group of UEs (not shown in Figure 1 ) through a sidelink groupcast transmission session. Also, the UE 101a can transmit data to the UE 101b and other UEs (not shown in Figure 1 ) through a sidelink broadcast transmission session.

[0026] Alternatively, according to some other embodiments of the application, Figure 1 , the UE 101b acts as a Tx UE and transmits V2X messages, and the UE 101a acts as an Rx UE and receives V2X messages from the UE 101b.

[0027] According to some embodiments of the application, Figure 1In some embodiments of the disclosure, the UEs 101 can be grouped into one or more groups, and each group includes a leader UE and one or more member UEs. For example, the UE 101a acts as a member UE and the UE 101b acts as a leader UE. In another example, the UE 101a acts as a leader UE and the UE 101b acts as a member UE.

[0028] Figure 1 Both the UE 101a and the UE 101b in embodiments of the disclosure can transmit information to and receive control information from the BS 102, e.g., via LTE or NR Uu interface. The BS(s) 102 can be distributed throughout an area. In certain embodiments of the present application, each of the BS(s) 102 can also be referred to as an access point, an access terminal, a base, a base unit, a macro base unit, a Node-B, an evolved Node B (eNB), a gNB, a home Node-B, a relay node, or a device, or be described using some other terminology, as is commonly used in the art. The BS(s) 102 are generally part of a radio access network that can include one or more controllers that can be communicably coupled to one or more corresponding BSs 102.

[0029] The wireless communication system 100 can be compatible with any type of network capable of sending and receiving wireless communication signals. For example, the wireless communication system 100 is compatible with wireless communication networks, cellular telephone networks, time division multiple access (TDMA) based networks, code division multiple access (CDMA) based networks, orthogonal frequency division multiple access (OFDMA) based networks, LTE networks, 3GPP based networks, 3GPP 5G networks, satellite communication networks, high altitude platform networks, and / or other communication networks.

[0030] In some embodiments of the present application, the wireless communication system 100 is compatible with 5G NR of the 3GPP protocol, where the BS(s) 102 transmit data using an OFDM modulation scheme on the downlink (DL) and the UE(s) 101 transmit data using a discrete Fourier transform spread orthogonal frequency-division multiplexing (DFT-S-OFDM) or cyclic prefix OFDM (CP-OFDM) scheme on the uplink (UL). More generally, however, the wireless communication system 100 can implement some other open or proprietary communication protocol, such as WiMAX, among other protocols.

[0031] In some embodiments of the present application, the BS(s) 102 can communicate using other communication protocols, such as wireless communication protocols of the IEEE 802.11 family. Also, in some embodiments of the present application, the BS(s) 102 can communicate via licensed spectrum, while in other embodiments the BS(s) 102 can communicate via unlicensed spectrum. The present application is not intended to be limited to implementation of any particular wireless communication system architecture or protocol. In still other embodiments of the present application, the BS(s) 102 can communicate with the UE(s) 101 using 3GPP 5G protocols.

[0032] In 3GPP standard document TS 36.300 [2], the design related to partial sensing for UEs (e.g., PUEs) is as follows. A resource pool for transmitting UEs (e.g., PUEs) can overlap with resources used for V2X sidelink communications. For each transmission pool, a resource selection mechanism (i.e., a random selection procedure, or a partial sensing based selection mechanism) that is allowed to be used in this transmission pool is also configured. The partial sensing based selection mechanism can also be named as partial sensing based resource selection mechanism, partial sensing mechanism, partial sensing procedure, or the like. If a UE (e.g., PUE) is configured to use either a random selection mechanism or a partial sensing based selection mechanism for one transmission pool, the specific resource selection mechanism is selected by implementation of the UE.

[0033] If a UE (e.g., PUE) is configured to use only a partial sensing based selection mechanism, the UE shall use the partial sensing based selection mechanism in the pool. Since only partial sensing operation is allowed, the UE shall not do random selection mechanism in the pool. If a BS does not provide a random selection pool, a UE that only supports random selection mechanism cannot perform sidelink transmission. In an exceptional pool, the UE uses a random selection mechanism.

[0034] According to 3GPP standard document TS 36.213 [4], if a UE (e.g., PUE) is configured to use a partial sensing based selection mechanism, the UE will only monitor resources in a subset of subframes. Compared with a random selection mechanism, a partial sensing based selection mechanism can reduce the probability of resource collision. Compared with a full sensing based selection mechanism, a partial sensing based selection mechanism can achieve power saving to some extent.

[0035] When a UE (e.g., PUE) is configured to use a partial sensing based selection mechanism, the UE will only monitor resources in a subset of subframes. Compared with a random selection mechanism, a partial sensing based selection mechanism can reduce the probability of resource collision. Compared with a full sensing based selection mechanism, a partial sensing based selection mechanism can achieve power saving to some extent. Figure 1When the UE 101a or UE 101b (illustrated and shown in FIG. 1 ) performs a partial sensing-based selection mechanism or a partial sensing-based reselection mechanism, the UE should be sensed over a periodic sensing window with all allowed resource reservations configured by higher layers before using the sensing result(s) for the resource reselection mechanism. The UE may not know when the resource selection or reselection process will be performed, and therefore, the UE's sensing window should be periodic. Without loss of generality, if the first time unit (e.g., a subframe in the time and frequency domains) of the partial sensing window is used as the starting point of the partial sensing cycle, the distribution of the partial sensing windows in the time domain may be Figure 2 In display.

[0036] Figure 2 An exemplary distribution of partial sensing windows in the time domain according to some embodiments of the present application is illustrated.

[0037] It can be seen that in Figure 2 In the embodiment of the present invention, there are three partial sensing cycles in the partial sensing window, and each partial sensing cycle (eg, Figure 2 The partial sensing cycle shown in FIG) includes an ON sensing duration (e.g., Figure 2 ) and OFF duration (e.g., Figure 2 ). It is contemplated that in some other embodiments of the present application, there may be a greater or lesser number of partial sensing cycles in the partial sensing window.

[0038] The on-sensing duration of a partial sensing cycle may also be named as the on-sensing duration of the partial sensing cycle, the sensing active time of the partial sensing cycle, the sensing active time of the partial sensing cycle, or the like. The off-sensing duration of a partial sensing cycle may also be named as the off-sensing duration of the partial sensing cycle, the sensing inactive time of the partial sensing cycle, the sensing inactive time of the partial sensing cycle, or the like.

[0039] Currently, resource selection based on sensing or partial sensing was initially introduced in 3GPP Release 14 V2X for vehicle UEs (VUEs) and pedestrian UEs (PUEs) operating in Mode 2. In this case, a UE in Mode 2 can determine resource selection based solely on its own sensing results. In 3GPP Release 16, UEs can be grouped together to facilitate internal information exchange between UEs and roadside units (RSUs).

[0040] For example, "vehicle platooning" enables vehicles to dynamically form a group that travel together, allowing the grouped vehicles to drive automatically via exchanging internal information. "Extended sensors" enable exchanging raw or processed data collected by local sensors or live video data among vehicles, RSUs, pedestrians' devices, and V2X application servers. In this case, vehicles can enhance their perception of their environment beyond what their own sensors can detect and have a more holistic view of the local situation. In "advanced driving," each vehicle and / or RSU shares data obtained from its local sensors with proximate vehicles, and thus it allows vehicles to coordinate their trajectories or maneuvers. In addition, each vehicle shares its driving intent with proximate vehicles.

[0041] Then, for sidelink communication in mode 2, it is needed to solve how to utilize the cooperation feature among multiple UEs to facilitate sensing and partial sensing based resource allocation while guaranteeing power saving. However, details on how to solve this problem have not been defined.

[0042] Some embodiments of the present application provide a sensing measurement and reporting mechanism to enable a UE to effectively utilize the sensing results measured by other UEs without the need to build a connection among them. Some embodiments of the present application provide a method for requesting sensing report configuration information. Some embodiments of the present application provide a method for transmitting sensing report configuration information. Some embodiments of the present application provide an apparatus for requesting sensing report configuration information. Some embodiments of the present application provide an apparatus for transmitting sensing report configuration information.

[0043] Figure 3 A flowchart of a method of wireless communication in accordance with some embodiments of the present application is illustrated. Figure 3 Embodiments of the present application can be performed by a UE (e.g., Figure 1 UE 101a or UE 101b) as illustrated and shown in FIG. 1. The UE can be a PUE or a VUE. The UE can function as a member UE. The sensing result request and reporting function can be enabled or disabled for the UE.

[0044] In Figure 3 In the exemplary method 300 as shown in FIG. 3, in operation 301, the UE receives sensing report configuration information. In some embodiments, the UE transmits a sensing report configuration request and then receives the sensing report configuration information.

[0045] In some embodiments, the UE receives pedestrian-to-anything (P2X) resource selection configuration information for a selected resource pool, and the P2X resource selection configuration information includes the sensing report configuration information. The P2X resource selection configuration information can be represented by resourceSelectionConfigP2X.

[0046] In some other embodiments, the UE receives Vehicle-to-Everything (V2X) resource selection configuration information for a selected resource pool, and the V2X resource selection configuration information includes sensing report configuration information. The V2X resource selection configuration information can be represented by resourceSelectionConfigV2X.

[0047] The sensing report configuration information can include linking information between a set of sidelink resources for the UE, a sensing result request resource, and a sensing result report resource. The linking information can include at least one of:

[0048] (1) a time and frequency offset between the set of sidelink resources for the UE and the sensing result request resource;

[0049] (2) a time and frequency offset between the set of sidelink resources for the UE and the sensing result report resource; and

[0050] (3) a time and frequency offset between the sensing result request resource and the sensing result report resource.

[0051] The sensing report configuration information indicates configuration(s) of sensing result request and report, and can be represented by Sesnsing-ReportConfig. Sesnsing-ReportConfig can be configured by radio resource control (RRC) signaling, MAC control element (CE), sidelink control information (SCI) signaling, or downlink control information (DCI) signaling. The set of sidelink resources for the UE indicates a sensing window, and can be represented by SensingWindow. The sensing result request resource can be represented by RequestResource. The sensing result report resource can be represented by RequestResource.

[0052] In some embodiments of the present application, Sesnsing-ReportConfig explicitly or implicitly includes an identification of the UE. The identification of the UE can be represented by ueID. The ueID can be associated with each detection window, and is indicated in Sesnsing-ReportConfig. The ueID can be a full-size UE identification. The ueID can be only an index within a set of identifiers.

[0053] In one example, the ueID can be explicitly indicated in Sesnsing-ReportConfig. In another example, the ueID can be implicitly indicated in Sesnsing-ReportConfig. For example, a set of SensingWindow for a set of UEs will be indicated according to an ordered sequence of ueIDs.

[0054] In some embodiments of the present application, the Sesnsing-ReportConfig can include at least one of the following: a set of sidelink resources for the UE, a sensing result request resource, a sensing result report resource, a candidate resource range for the UE, a traffic type, a traffic priority, and a transmission type. The set of sidelink resources for the UE can be represented by a SensingWindow. The sensing result request resource can be represented by a RequestResource. The sensing result report resource can be represented by a RequestResource. The candidate resource range for the UE can be represented by a CandidateResource. The value of the CandidateResource can be represented by a resource in time domain and / or frequency domain.

[0055] The traffic type can be represented by a TrafficType. For example, the traffic type can be one of the following: a periodic traffic type, an aperiodic traffic type, a pedestrian-to-anything (P2X) traffic type, and a vehicle-to-anything (V2X) traffic type.

[0056] The traffic priority can be represented by a TrafficPriority. For example, the traffic priority can be one of the following: a proximity service per-packet priority (PPPP) defined in long term evolution (LTE) sidelink, and a priority defined in PC5 5G QoS identifier (PQI).

[0057] The transmission type can be represented by a TransmissionType. For example, the transmission type can be one of the following: an initial transmission type, and a retransmission type.

[0058] The Sesnsing-ReportConfig can include one or more sensing report configuration items, and the sensing result message corresponds to a subset of the one or more sensing report configuration items. In Figure 8 Exemplary details of these items are described in the embodiments.

[0059] The operation of sensing or measurement can be performed on a set of sidelink resources, i.e., a SensingWindow, in order to derive the number or numbers of resources to be reported. The SensingWindow can be represented by a resource in time domain and / or frequency domain. For example, the SensingWindow can be represented in a resource pool by the following:

[0060] (1) a set of indices of subframes;

[0061] (2) an index of a boundary subframe;

[0062] (3) an index of a starting subframe of the SensingWindow and a size of the SensingWindow (i.e., a total number of subframes);

[0063] or

[0064] (4) Subframe offset from previous SensingWindow and size of SensingWindow (i.e., total number of subframes).

[0065] In some embodiments of the present application, SensingWindow is configured for periodic, semi-persistent, or aperiodic.

[0066] • Periodic SensingWindow occurs in every periodSW subframe. The value of periodicity of periodSW can be configured in Sensing-ReportConfig.

[0067] • For semi-persistent SensingWindow, a certain periodicity can be configured. The operation of sensing result request and reporting can be initiated or de-initiated based on MAC control element (MAC CE).

[0068] • For aperiodic SensingWindow, no periodicity is configured. The UE is explicitly triggered for each operation of sensing result request and reporting, e.g., by sidelink control information (SCI) signaling.

[0069] For different sensing report configuration entries within Sensing-ReportConfig, the mode of SensingWindow (i.e., consecutive or non-consecutive) or the size of SensingWindow (i.e., total number of subframes) can be the same or different.

[0070] In operation 302 of the exemplary method 300, the UE determines whether to transmit a sensing result message based on the received sensing report configuration information.

[0071] In operation 303 of the exemplary method 300, in response to the determination to transmit the sensing result message, the UE transmits the sensing result message.

[0072] In some embodiments of the present application, the sensing result message in operation 303 is a sensing result request. The UE can transmit a sensing result request for a sensing result request resource. The sensing result request resource can be determined based on the sensing report configuration information received in operation 301 of the exemplary method 300. In an embodiment, the UE further determines whether to transmit the sensing result request based on:

[0073] (1) Resource selection trigger time or resource reselection trigger time of the UE (e.g., time instance “n” shown in the embodiment of FIG. 1); Figure 4

[0074] (2) Whether the sensing result request resource is available; and ​

[0075] (3) UE's candidate resource range (i.e., CandidateResource).

[0076] In some other embodiments of the present application, the sensing result message in operation 303 is a sensing result report. For example, the sensing result report can include the reserved resource(s) in the given resource range CandidateResource, and the reserved resource(s) are reserved by certain traffic defined by TrafficType, TrafficPriority or TransmissionType, and detected within the UE's SensingWindow. In an alternative example, the sensing result report can include the recommended resource(s) in the given resource range CandidateResource, and the recommended resource(s) are determined based on the sensing result detected within the UE's SensingWindow.

[0077] If the above two examples of the report content within the sensing result report are both supported in some embodiments, the different content can be indicated by the "report type" defined in the field "report message", Figure 8 For example, the "report type" can indicate that the sensing result report is used to report the reserved resource(s), or the sensing result report is used to report the recommended resource(s).

[0078] In an embodiment, the UE first receives a sensing result request for a sensing result request resource, and then transmits a sensing result report for a sensing result report resource in response to the received sensing result request indicating that the UE meets the reporting condition.

[0079] In another embodiment, the UE first determines whether the detected energy on the sensing result request is higher than a predefined threshold; and then, in response to the energy being higher than the predefined threshold, the UE transmits a sensing result report for a sensing result report resource.

[0080] The details described in all the foregoing embodiments of the present application (e.g., the specific operations of the UE's sensing result report and related parameters) are applicable to Figures 4 to 8 all the embodiments shown in

[0081] Figure 4 An example of the selection mechanism based on exemplary partial sensing is illustrated according to some embodiments of the present application.

[0082] Figure 4 Three partial sensing windows, i.e., sensing window 1, sensing window 2 and sensing window 3, of three UEs are shown. Although Figure 4The sensing window 1, the sensing window 2 and the sensing window 3 are not overlapped as shown, but in some other embodiments of the present application, these partial sensing windows can be overlapped in time domain and / or frequency domain.

[0083] According to Figure 4 Embodiments, three UEs are configured with partial sensing based resource selection mechanism, and correspond to three partial sensing windows respectively. For example, the three UEs are UE1, UE2 and UE3 respectively, and each of them can be Figure 1 UE 101a or UE 101b as shown and demonstrated in FIG. 1, or Figure 1 another UE not shown in FIG. 1. UE1 senses on “sensing window 1” with all allowed resource reservation periodicities configured by higher layer, UE2 senses on “sensing window 2” with all allowed resource reservation periodicities configured by higher layer, and UE3 senses on “sensing window 3” with all allowed resource reservation periodicities configured by higher layer. It can be considered that there can be different correspondence between UEs and partial sensing windows, and it does not limit the principles of the present application.

[0084] The sensing results obtained in “sensing window 1” can be used to determine one or more candidate resources for PSCCH transmission and / or PSSCH transmission in a resource selection window. Then, at time instance “n”, resource selection (or reselection) can be triggered. Figure 4 As shown in FIG. 2, the resource (re)selection trigger is time instance “n”. Then, for PSCCH transmission and / or PSSCH transmission based on the sensing results obtained from “sensing window 1”, UE1 can determine one or more candidate resources in “resource selection window 1” between time instance “n” and time instance “n+T2”. T2 is a time period greater than 0. For example, the value range and determination method of T2 can be determined as specified in 3GPP standard documents.

[0085] Although resource (re)selection can be triggered at time instance “n”, UE1 can not determine one or more candidate resources at time instance “n” because there can be processing delay of UE1. The processing delay T1 of UE1 can be greater than or equal to 0. For example, the value range and determination method of T1 can be determined as specified in 3GPP standard documents.

[0086] Figure 4 As shown in FIG. 3, in “resource selection window 1” of UE1, another UE (e.g. VUE) can transmit aperiodic transmission. The aperiodic transmission can include an initial transmission (e.g. “initial transmission” as shown in FIG. 4) coupled with two retransmissions (e.g. “coupled retransmission” as shown in FIG. 4). Figure 4 As shown in FIG. 3, in “resource selection window 1” of UE1, another UE (e.g. VUE) can transmit aperiodic transmission. The aperiodic transmission can include an initial transmission (e.g. “initial transmission” as shown in FIG. 4) coupled with two retransmissions (e.g. “coupled retransmission” as shown in FIG. 4). Figure 4 As shown in FIG. 3, in “resource selection window 1” of UE1, another UE (e.g. VUE) can transmit aperiodic transmission. The aperiodic transmission can include an initial transmission (e.g. “initial transmission” as shown in FIG. 4) coupled with two retransmissions (e.g. “coupled retransmission” as shown in FIG. 4). Figure 4It can be seen that the initial transmission is within the "sensing window 3" of UE 3, and the two coupled retransmissions are within the "resource selection window 1" of UE 1. The initial transmission and the two coupled retransmissions can be transmitted by UE 2, or by a UE different from UE 1, UE 2, and UE 3. Since the transmission pattern of the aperiodic transmissions (i.e., the initial transmission and the two coupled retransmissions) is unpredictable, it cannot be sensed by UE 1. Therefore, for P2X related sidelink communications, aperiodic transmissions are highly likely to collide with the candidate resources determined based on the partial sensing mechanism.

[0087] In some embodiments of the present application, the resource for UE to transmit the sensing result report can be defined as "resource for reporting" or "reporting resource", which can be denoted by ReportResource. Reference Figure 4 , the black block denoted by p i indicates the available sidelink (PSCCH or PSSCH) resources of ReportResource. The sensing result report of a UE can be denoted by Sensing-ResultReport. There is a link between SensingWindow and ReportResource. The reporting resource can follow its corresponding SensingWindow configuration or scheduling. The link can be done by describing the ReportResource with certain time and frequency offset from a certain reference resource block of the corresponding SensingWindow.

[0088] In some embodiments of the present application, the resource for the request of UE to transmit the sensing result report can be defined as "resource for request" or "request resource", which can be denoted by RequestResource. The request for the sensing result report can also be named as "sensing result request", and can be denoted by Sensing-ResultRequest. There is also a link between SensingWindow and RequestResource. The link can be done by describing the RequestResource with certain time and frequency offset from a certain reference resource block of the corresponding SensingWindow. Reference Figure 4 , the grid block denoted by q i indicates the available sidelink (PSCCH or PSSCH) resources of RequestResource. Preferably, RequestResource is within the range of SensingWindow. In that case, the UE will not perform additional sensing and detection for Sensing-ResultRequest.

[0089] The time and frequency offset of a RequestResource or a ReportResource can be fixed. For example, a RequestResource or a ReportResource is pre-configured, e.g., in a resource pool. The time and frequency offset of a RequestResource or a ReportResource can be dynamic. For example, a RequestResource or a ReportResource is scheduled by a UE or a network (e.g., a BS). The specific time and frequency location of a RequestResource or a ReportResource in different sensing windows can be different.

[0090] In particular, Figure 4 Embodiments of the present disclosure show three resources (i.e., q1, q2, and q3) for requesting and three resources (i.e., p1, p2, and p3) for reporting associated with “Sensing Window 1”, “Sensing Window 2”, and “Sensing Window 3”, respectively. “Sensing Window 1” can be denoted by SensingWindow#1. “Sensing Window 2” can be denoted by SensingWindow#2. “Sensing Window 3” can be denoted by SensingWindow#3. Figure 4 “Resource Selection Window 1” in embodiments of the present disclosure includes Figure 4 Candidate Resource 1 shown in FIG. 1, which can be denoted by CandidateResource#1.

[0091] In Figure 4 In embodiments of the present disclosure, when the reporting condition(s) is / are satisfied, UE1 configured with SensingWindow#1 will report the sensing result on resource p1 in its SensingWindow#1 according to the configuration, when the reporting condition(s) is / are satisfied, UE2 configured with SensingWindow#2 will report its number on resource p2, and when the reporting condition(s) is / are satisfied, UE3 configured with SensingWindow#3 will report its number on resource p3. The reporting operation of UE1, UE2, and UE3 can be periodic, semi-persistent, or aperiodic, and follow the configuration of their corresponding sensing window.

[0092] In Figure 4 In embodiments of the present disclosure, if there is Figure 4 the processing delay of UE1 “T1” shown in FIG. 1, which is greater than 0, and Figure 4As shown in FIG. 6, the starting time of CandidateResource#1 is time instant "n+Tx", then UE1 can determine whether there is available RequestResouce and ReportResource between the time interval of [n+T1, n+Tx]. In response to there is available RequestResouce and ReportResource between the time interval of [n+T1, n+Tx], UE1 can determine to send the sensing result request.

[0093] In embodiments of the operation of pre-configuring sensing result request and reporting in a resource pool, the procedure of UE in higher layer and the procedure of UE in physical layer are described as follows. In these embodiments, Sensing-ReportConfig can be indicated by network via configurable parameters, or can be pre-configured in a resource pool.

[0094] Regarding the procedure of UE in higher layer

[0095] In particular, if a UE is configured to transmit P2X related V2X sidelink communications, if the UE determines lower layers to transmit P2X related V2X sidelink communications based on partial sensing procedure using a selected resource pool, and if Sensing-ReportConfig is included in P2X resource selection configuration information (i.e., resourceSelectionConfigP2X) of the selected resource pool, the UE shall configure lower layers to transmit sidelink control information and corresponding data based on partial sensing procedure using the selected resource pool coupled with sensing result request and reporting function.

[0096] If a UE is configured to transmit V2X sidelink communications, if the UE determines lower layers to transmit V2X sidelink communications based on sensing procedure using a selected resource pool, and if Sensing-ReportConfig is included in V2X resource selection configuration information (i.e., resourceSelectionConfigV2X) of the selected pool, the UE shall configure lower layers to transmit sidelink control information and corresponding data using the selected resource pool coupled with sensing result request and reporting function.

[0097] Regarding the procedure of UE in physical layer, if Sensing-ReportConfig is configured for a UE by higher layer, the following embodiments of step are used when identifying candidate resource(s) within a resource selection window. Figure 5 The legacy of identifying candidate resource(s) within a resource selection window includes the following steps, for example, partial sensing based resource selection specified in 3GPP Release 14 V2X for pedestrian UEs (PUEs) operating in Mode 2.

[0098] (1) UE (e.g. Figure 4 UE1 in the example should determine a set of subframes within the interval [n+T1, n+T2] (which can be represented by the original candidate resource set S) through its implementation. Figure 4 The "candidate resource 1" shown in is S.

[0099] (2) UE based on the partial sensing window of UE (e.g. Figure 4 Based on the sensing results detected in the sensing window 1), the reserved (several) resources in S are excluded from S.

[0100] (3) The UE further determines (several) candidate resources from (several) remaining resources in S based on the energy detection result of the resources in S.

[0101] In this application, a UE (e.g. Figure 4 UE1 in the present invention may incorporate the sensing result report obtained from other UEs (e.g., UE3) into the operation of identifying (several) candidate resources. Specifically, the UE may utilize the sensing result report in the following operations: (1) determining a group of subframes as the original candidate resource group S; and / or (2) excluding the resources reserved in S from S; and / or (3) further determining (several) remaining candidate resources in S based on the sensing results detected in the partial sensing window of the UE and indicated in the sensing result report. For example, if the sensing result report obtained by UE1 from other UE3 includes (several) reserved resources (e.g., Figure 4 , two coupled retransmissions reserved in "Candidate Resource 1" by an aperiodic transmission), then the reserved resource(s) may be removed from S by UE1 in order to avoid resource conflicts between UE1's transmission and the detected aperiodic transmission. Figure 4 , the reservation information of the two coupled retransmissions is detected in the initial transmission of the aperiodic transmission within "sensing window 3". In an alternative example, if the sensing result report obtained by UE1 from other UE3 includes (several) recommended resources, UE1 may consider the (several) recommended resources in further determining (several) candidate resources among (several) remaining resources in S.

[0102] Figure 5 An exemplary flow chart for sensing result request and reporting according to some embodiments of the present application is illustrated. Figure 5 Examples and Figure 4 and Figure 5 UE1 and UE3 in the table represent UE1 and UE3 respectively, and the above Figure 4 The corresponding functions and operations of UE1 and UE3 described in the embodiment of FIG. Figure 5UE1 and UE3 in FIG. 1 can refer to other UEs performing similar functions and operations, and the specific names of UE1 and UE3 can change in different embodiments, e.g., UEx and UEy.

[0103] In an embodiment of FIG. 1, if resource (re)selection is triggered at “n”, UE1 can determine a sensing result request (i.e., Sensing-ResultRequest) at q3; if resource (re)selection is triggered at “n”, UE1 can determine Sensing-ResultRequest at q2 and q3, respectively; and if resource (re)selection is triggered at “n”, UE1 can determine not to send Sensing-ResultRequest because no RequestResource is available. Figure 4

[0104] In an embodiment of FIG. 1, if resource (re)selection is triggered at “n”, UE1 can determine a sensing result request (i.e., Sensing-ResultRequest) at q3; if resource (re)selection is triggered at “n”, UE1 can determine Sensing-ResultRequest at q2 and q3, respectively; and if resource (re)selection is triggered at “n”, UE1 can determine not to send Sensing-ResultRequest because no RequestResource is available. Figure 4 Figure 5 An embodiment of FIG. 1 assumes that UE1 selects CandidateResource#1 and is associated with SensingWindow#1, and UE3 is associated with SensingWindow#3. When resource (re)selection is triggered at “n”, UE1 determines whether to send a sensing result request (i.e., Sensing-ResultRequest) based on time instant “n”, available RequestResouce, available ReportResource, and its CandidateResource (i.e., CandidateResource#1).

[0105] For example, UE1 determines whether there is an available RequestResouce and associated ReportResource between time instant “n” and CandidateResource#1. In response to there being an available RequestResouce and associated ReportResource between time instant “n” and CandidateResource#1, UE can determine to send a sensing result request.

[0106] In step 501 of FIG. 1, if UE1 determines to send a sensing result request (i.e., Sensing-ResultRequest), UE1 will send Sensing-ResultRequest to the corresponding RequestResource. UE1 will send Sensing-ResultRequest via broadcast or groupcast through sidelink communication. Figure 5

[0107] In step 501 of FIG. 1, if UE1 determines to send a sensing result request (i.e., Sensing-ResultRequest), UE1 will send Sensing-ResultRequest to the corresponding RequestResource. UE1 will send Sensing-ResultRequest via broadcast or groupcast through sidelink communication. Figure 5 ​​​In an embodiment of the method, if RequestResource is included in SensingWindow#3 of UE3, UE3 will detect Sensing-ResultRequest during its sensing operation. If UE3 satisfies the reporting condition, UE3 determines whether to send Sensing-ResultReport for the corresponding ReportResource according to the indication of Sensing-ResultRequest. In an embodiment of the method, if RequestResource is included in SensingWindow#3 of UE3, UE3 will detect Sensing-ResultRequest during its sensing operation. If UE3 satisfies the reporting condition, UE3 determines whether to send Sensing-ResultReport for the corresponding ReportResource according to the indication of Sensing-ResultRequest. In Figure 5 In step 502 of the method, if UE3 determines to send sensing result report (i.e., Sensing-ResultReport), UE3 will send Sensing-ResultReport for the corresponding ReportResource. UE3 will send Sensing-ResultReport via broadcast or groupcast through sidelink communication.

[0108] For example, if the energy detected on Sensing-ResultRequest is higher than a predefined threshold, UE3 determines to send Sensing-ResultReport for the corresponding ReportResource according to the indication of Sensing-ResultRequest.

[0109] In some embodiments of the method, for another UE different from UE1 or UE3, if this UE senses and detects that Sensing-ResultRequest is not set, this UE can use the corresponding ReportResource for transmission if needed. Otherwise, if this UE senses and detects that Sensing-ResultRequest is set, this UE will avoid using the corresponding ReportResource for transmission.

[0110] Figure 6 Another flowchart illustrating a method of wireless communication according to some embodiments of the present application. Figure 6 Embodiments of the method can be performed by a leading UE (e.g., Figure 1 UE 101a or UE 101b) illustrated and shown in FIG. 1.

[0111] In some embodiments of the method, Figure 6In an embodiment, in step 601, the UE or the network (e.g., the base station) receives a sensing report configuration request. In step 602, the UE or the network determines sensing report configuration information (i.e., Sesnsing-ReportConfig). Sesnsing-ReportConfig includes linking information between SensingWindow, RequestResource, and ReportResource. In step 603, the UE or the network transmits the sensing report configuration information.

[0112] exist Figures 1 to 5 The details described in the embodiments illustrated and shown in FIG, especially those related to the sensing result request and reporting process, are applicable to Figure 6 In addition, Figure 6 The details described in the embodiments apply to Figures 1 to 5 and all embodiments 7 to 9.

[0113] In an embodiment where the operation of the sensing result request and report is scheduled by the UE or the network (e.g., the BS), the process for the UE to configure is described as follows. In an embodiment where the network determines the Sensing-ReportConfig of the UE, the network may transmit the Sensing-ReportConfig to the UE via RRC signaling, MAC CE, or DCI signaling. Figure 7 Specific examples are described in .

[0114] Figure 7 Another exemplary flow chart for sensing result request and reporting according to some embodiments of the present application is described. Figure 7 In the embodiment of the present invention, the member UE may be Figure 4 and 5 UE1 described in , and the leading UE may be Figure 4 and 5 UE2 or UE3 described in , or another UE (eg, UEx) in different embodiments. Figure 7 In the embodiment of the present invention, the member UE may be Figure 1 UE 101a or UE 101b as described and shown in FIG, and the leading UE may be Figure 1 UE 101b or UE 101a as described and shown in FIG.

[0115] In step 701, a member UE sends a sensing report configuration request to a leader UE. The sensing report configuration request may be named a request for sensing report configuration or similar. The request indicates that the member UE supports the related functions of sensing result request and reporting.

[0116] In step 702, the sensing result request and reporting function is enabled through higher layer signaling. When enabled, the leader UE will determine Sensing-ReportConfig for the member UEs in response to the received sensing report configuration request.

[0117] In step 703, the leader UE sends sensing report configuration information to the member UEs to indicate Sensing-ReportConfig to the member UEs. The indication may be conveyed via RRC signaling, MAC CE, or SCI signaling.

[0118] Figure 8 The following describes exemplary sensing report configuration information according to some embodiments of the present application. Figure 8 Explanation of exemplary Sensing-ReportConfig. It is considered that the Sensing-ReportConfig in this application may include Figure 8 The elements or items in more or less other elements or items, and may contain Figure 8 The elements or items in the are different elements or items.

[0119] exist Figure 8 In the embodiment, each configuration contains Figure 8 One or more configuration items indicated by the index in column 1 of . Each configuration item in Sensing-ReportConfig contains three fields: "Report Quantity", "Request Message" and "Report Message". Specifically:

[0120] The report quantity further includes service type, service priority, transmission type, sensing window configuration, and candidate resource configuration. The sensing window configuration refers to the set of sidelink resources in the time and frequency domains for the UE and can be represented by SensingWindow. The candidate resource configuration refers to the range of candidate resources for the UE and can be represented by CandidateResource.

[0121] The request message further includes a request type and / or a requested resource. The request type may include, for example, one digit, X digits, or a bit string.

[0122] The report message further contains a report type and / or report resources. The report type can be periodic, semi-persistent, or aperiodic. Alternatively, the report type can indicate whether the sensing result report includes (several) reserved resources or (several) recommended resources.

[0123] In some embodiments of the present application, the Sensing-ResultRequest may be formatted as follows:

[0124] (1) Sensing-ResultRequest is one bit. If Sensing-ResultRequest is set to 1, and if Sensing-ResultRequest is transmitted for RequestResource associated with SensingWindow #j (e.g., in step 701 in the embodiment of Figure 7 FIG. 6), then the result of sensing in SensingWindow #j based on the default configuration entry (i.e., the last line "default" in the embodiment of Figure 8 FIG. 6) should be reported (e.g., in step 703 in the embodiment of Figure 7 FIG. 6). The default configuration entry can indicate a sensing result report indicating the resource(s) reserved by some traffic defined by TrafficType, TrafficPriority, or TransmissionType in the given resource range CandidateResource #k and detected within SensingWindow #j.

[0125] (2) Sensing-ResultRequest is an X-bit field indicating an index to the Sesnsing-ReportConfig table, Figure 8 shown in FIG. 6. If Sensing-ResultRequest is set to its value domain (e.g., #i), and if Sensing-ResultRequest is transmitted for RequestResource associated with SensingWindow #j i (e.g., in step 701 in the embodiment of Figure 7 FIG. 6), then the result of sensing in SensingWindow #j based on configuration entry #i should be reported (e.g., in step 703 in the embodiment of Figure 7 FIG. 6). The configuration entry can indicate a sensing result report indicating the resource(s) reserved by some traffic defined by TrafficType, TrafficPriority, or TransmissionType in the given resource range CandidateResource #k i and detected within SensingWindow #j. i

[0126] For example, if i = 2, then the result of sensing in SensingWindow #j2 based on the configuration entry indicated by the index "#2" in the fourth line of the embodiment of Figure 8 FIG. 6 should be reported.

[0127] ​(3) Sensing-ResultRequest is a bit string whose size (i.e., total number of configuration items) is Sensing-ReportConfig. If the i-th bit of Sensing-ResultRequest is set to 1, and if the transmission of Sensing-ResultReport for RequestResource#j i associated with RequestResource is triggered, then the result detected in SensingWindow#j i based on configuration item#i should be reported. In each bit string, one or more bits can be set to 1 simultaneously. A configuration item can indicate a sensing result report indicating the resource(s) reserved by certain traffic defined by TrafficType, TrafficPriority or TransmissionType in a given resource range CandidateResource#k i in SensingWindow#j i .
