[0029] The example titles of the following sections are used to facilitate understanding of the disclosed subject matter and do not limit the scope of the claimed subject matter in any way. Therefore, one or more features of one example section can be combined with one or more features of another example section. In addition, for clarity of explanation, 5G terminology is used, but the technology disclosed in this document is not limited to 5G technology and can be used in wireless systems that implement other protocols.

[0030] I. Transmission opportunities for unlicensed sidelink positioning

[0031] The number of transmission opportunities may be defined by M, and the maximum number of transmission opportunities may be defined by N, where M ≥ N, and M, N are integers. In some example embodiments, the number of transmission opportunities M may represent the total number of transmission opportunities in one and / or each time period (e.g., a radio frame, a specific duration, etc.). In some example embodiments, the number of transmission opportunities M may represent the number of partial transmission opportunities in one and / or each time period, and P may define the total number of transmission opportunities in one and / or each time period such that P = Q*M. That is, in some example embodiments, or

[0032] In various embodiments, sidelink control information (SCI) triggers positioning reference signal (PRS) transmission, PRS period, PRS window. In various embodiments, SCI precedes the triggered resource. In various embodiments, each of at least one of M, N, or Q can be configured using any one or more of the following: default value, SCI, radio resource control (RRC), downlink control information (DCI), media access control control element (MAC CE), non-access stratum (NAS), higher layer parameters, or system information block x (SIBx), where x is an integer.

[0033] II. Relationship between PRS Quiet Pattern Information and Unlicensed Sidelink Positioning Transmission Opportunities

[0034] According to various embodiments, since the listen before talk (LBT) process and the silence pattern information are used for interference cancellation, the silence pattern information is not configured or enabled for side link positioning. In some example embodiments, at least the silence pattern information can be configured / enabled to extend the number of consecutive repetitions or parameter M. For example, the number of consecutive repetitions can be 1, 2, 4, 8, and / or other suitable integers. In some example embodiments, at least the silence pattern information can be configured or enabled across different repetitions using a bitmap. For example, for a given repetition, if the bitmap is 1 and the listen before talk (LBT) process results in a failure, the LBT process can be performed for the repetition with a bitmap of 0.

[0035] III. Indication of LBT in Sidelink Signal

[0036] In various embodiments, one or more PRS LBT parameters are indicated in the first region or the second region. The first region and the second region may include SCI information. For example, in one region, the SCI that may be carried on the PSCCH is the first level SCI for transmitting the sidelink scheduling information, while in another region, the SCI carried on the PSCCH is the second level SCI for transmitting the sidelink scheduling information.

[0037] In various embodiments, the LBT parameters for the sidelink signal may be preconfigured. In various embodiments, (multiple) LBT parameters are associated with (multiple) PRS parameters. In various embodiments, (multiple) PRS parameters include at least one of the following items: PRS duration, (multiple) PRS opportunities / number of repetitions in a PRS, or PRS priority. In various embodiments, one or more LBT parameters for SCI are associated with PRS parameters. In various embodiments, an SCI is associated with one or more PRS configurations. In various embodiments, SCI, PRS configurations, or PRS may use one of broadcast, unicast, and multicast. In various embodiments, LBT parameters may be generated based on components of the sidelink signal, based on certain locations of the sidelink signal or the presence of data in a time slot, etc. In various embodiments, the sidelink time slot may be one or more subframes, one or more parts within a subframe (e.g., one or more half frames), etc. For example, in some example embodiments, if there is no data in the sidelink timeslot of the SL-SSB, the LBT priority parameter for the sidelink synchronization signal block (SL-SSB) may be set to the highest priority value (e.g., p=1). In some examples, if there is data in the sidelink timeslot, the LBT priority parameter may be determined based on the LBT priority with data quality of service (QoS) and / or physical sidelink shared channel (PSSCH). In some examples, if there is data and a physical sidelink feedback channel (PSFCH), the LBT priority parameter may be determined based on the LBT priority associated with the PSFCH. In some examples, if there is data, PRS, and / or PSFCH in a sidelink timeslot or a sidelink specified duration, the LBT priority associated with at least one (or any one or more) of the data, PRS, and / or PSFCH may be used for the LBT priority parameter. In one non-limiting illustrative example, a sidelink timeslot may include a PRS associated with a high LBT priority and data associated with a low LBT priority, and the high LBT priority of the PRS may be used for the LBT priority parameter instead of the low LBT priority of the data. In another non-limiting illustrative example, a sidelink timeslot may include data associated with a high LBT priority (e.g., voice data) and a PRS associated with a low LBT priority, and the LBT priority parameter may be based on the high LBT priority of the data. In various embodiments, only type 1 LBT parameters are used in sidelink positioning. In various embodiments, a specified duration is a continuous logical resource in a sidelink resource configuration. IV. LBT Priority and PRS Priority

[0038] In various embodiments, the higher the PRS priority value, the higher the LBT priority parameter. Table 1 shows an example relationship between PRS priority values ​​and LBT priority parameters according to an example embodiment.

[0039]

[0040] Table 1

[0041] In various embodiments, parameters are used for association of PRS priority and LBT priority (CAPC: Channel Access Priority Class).

[0042] In various embodiments, the sidelink PRS uses parameters associated with uplink LBT or parameters associated with downlink LBT.

[0043] For the communication device, in various embodiments, if the LBT priority for the sidelink data is higher than the LBT priority for the sidelink PRS, the LBT process for the sidelink data starts before / before the LBT process for the sidelink PRS. Similarly, if the LBT priority for the sidelink PRS is higher than the LBT priority for the sidelink data, the LBT process for the sidelink PRS starts before / before the LBT process for the sidelink data.

[0044] In some example scenarios, the LBT priority for sidelink data may be the same as that for sidelink PRS, and in some example embodiments, the LBT process for sidelink data starts before / before the LBT process for sidelink PRS. In other example embodiments, in such example scenarios, the LBT process for sidelink PRS starts before / before the LBT process for sidelink data.

[0045] In various embodiments, a first sidelink PRS (PRS1) and a second sidelink PPS (PRS2) may be involved, and if the LBT priority for the first sidelink PRS is higher than the LBT priority for the second sidelink PRS, the LBT process for the first sidelink PRS starts before / before the LBT process for the second sidelink PRS. For the communication device, the LBT priority for the first sidelink PRS and the LBT priority for the second sidelink PRS may be the same, and the LBT is associated with the timing of the received PRS indication information. In some embodiments, the LBT may refer to the LBT priority for both sidelink PRS1 and sidelink PRS2.

[0046] In various embodiments, PRS LBT may be configured or default.

[0047] V.PRS transmission and resource block (RB) set

[0048] In various embodiments, the lowest resource block (RB) or resource element (RE) index of the PRS is aligned / associated with the start of each RB set. In various embodiments, the lowest RB / RE index of the PRS is aligned / associated with the start of all RB sets. In various embodiments, the lowest RB / RE index is aligned / associated with the start of a certain RB set.

[0049] In various embodiments, PRS is not transmitted in the gaps between RB sets in the frequency domain.

[0050] In various embodiments, the gap between RB sets is associated with PRS parameters or other parameters (eg, PRS bandwidth / PRS frequency domain occupancy length, UE capability).

[0051] VI. Sidelink Data Transmission and RB Grouping

[0052] Figure 1A-Figure 1D A diagram illustrating data subchannels and RB sets is provided. In various embodiments, sidelink data may be transmitted or valid in subchannels that do not overlap with RB sets. For example, Figure 1A "Data subchannel 1" shown, Figure 1C The "Data Subchannel 1" and Figure 1C The sidelink data in the "Data Subchannel 2" shown can be transmitted or is valid.

[0053] In various embodiments, sidelink data may be invalid in subchannels that do not overlap or partially overlap with an RB set. For example, Figure 1A "Data subchannel 2" shown, Figure 1B The "Data Subchannel 1" and Figure 1B The sidelink data in "Data Subchannel 2" shown may be invalid.

[0054] In various embodiments, the sidelink data may be invalid in subchannels where the control signal in the frequency domain does not overlap or partially overlaps with the RB set. Figure 1A "Data subchannel 2" shown, Figure 1B The "Data Subchannel 1" and Figure 1B The sidelink data in the "data subchannel 2" may be invalid.

[0055] In various embodiments, sidelink data is not transmitted in the gaps between RB sets in the frequency domain. Figure 1D The gap between two RB sets in which sidelink data is not transmitted is illustrated. Figure 1D "Data Subchannel 1" shown may be active. Figure 1DThe "Data Subchannel 2" shown may be invalid.

[0056] In various embodiments, sidelink data is transmitted in the frequency domain in the gaps between RB sets. Figure 1D The gap between two RB sets in which sidelink data is transmitted is illustrated. Figure 1D The "Data Sub-Channel 1" and "Data Sub-Channel 2" shown may be invalid.

[0058] VII. Sl-RS-ForSensing Configuration in Sidelink (If PRS is introduced)

[0059] sl-RS-ForSensing may be selected for different resource configurations for sidelink data and PRS, where at least one of the following is configured: a resource pool, a bandwidth part (BWP), a carrier frequency, or a subchannel. In various embodiments, the sl-RS-ForSensing parameter is selected for each different resource configuration. According to some example embodiments, for independently configured sidelink control information (SCI) for PRS, the sl-RS-ForSensing for PRS is configured with a demodulation reference signal (DMRS) of a PRS physical sidelink control channel (PSCCH). According to some example embodiments, for an independent PRS configuration associated with one or more data configurations, the SCI is included in the one or more data configurations, and the sl-RS-ForSensing parameter is configured as at least one of a PSCCH DM RS, a PSCCH DM RS, or a PSCCH DM-RS for the PRS. According to some example embodiments, if (multiple) PRS configurations and (multiple) data configurations are in the same configuration, the SCI is included in the (multiple) configurations and the sl-RS-ForSensing parameter is configured as at least one of PSCCH DM RS, PSCCH DM RS, or PSCCH DMRS of PRS.

[0060] VIII. Allowed Sidelink PRS

[0061] In various embodiments, if a standalone PRS configuration is introduced, the SL-SyncAllowed parameter is included in the standalone PRS configuration. In various embodiments, this parameter in the data configuration is associated with the PRS configuration or used in the PRS configuration, or the parameter is not included in the PRS configuration. In various embodiments, a PRS configuration list is configured and all configuration parameters can be reused according to the Third Generation Partnership Project (3GPP) Release 16 / 17. The PRS parameters that should be configured may include comb size, PRS period, etc.

[0062] IX. Sidelink PRS Sensing / Selection Window Parameters

[0063] In various embodiments, the sidelink data and the sidelink PRS may use the same or independent resource configuration. In various embodiments, the sidelink data and the sidelink PRS may use the same or different control information (e.g., one SCI set, different SCIs). Alternatively, the control information for the sidelink PRS may be included in the PSSCH.

[0082] According to the above, in some examples, the T2 parameter indicates the end of the selection window.As shown, in various embodiments, the T2 parameter can take a value greater than or equal to the T2min parameter and less than or equal to the packet delay budget.

In various embodiments, the UE receives one or more sl-SelectionWindowList parameters at a time prior to receiving one or more sidelink PRSs.

[0084] In the configuration example of the sl-SelectionWindowList parameter described above (eg, sl-SelectionWindowList-r16), the sl-Priority-r16 parameter indicates the priority of the data.

[0099] XI. Issues related to the sidelink irrelevant window

[0100] Figure 3 A diagram including a first time window (eg, a sensing window) and a second time window (eg, a selection window) for a SL_PRS and illustrating various embodiments is provided. Figure 3 Also included is a first time window (e.g., a sensing window) and a second time window (e.g., a selection window) for sidelink data. Figure 3 As shown, the sensing window for SL_PRS can be independent (e.g., with respect to frequency, with respect to time) of the sensing window for sidelink data, and the selection window for SL_PRS can be independent (e.g., with respect to frequency, with respect to time) of the selection window for sidelink data. For example, in some example scenarios, the sensing window for SL_PRS can occur earlier in time than the sensing window for sidelink data, or it can occur later in time than the sensing window for sidelink data. For example, in some example scenarios, the selection window for SL_PRS can occur earlier in time than the selection window for sidelink data, or it can occur later in time than the selection window for sidelink information.

[0101] Within the sensing window for SL_PRS and / or for sensing of sidelink data, the UE may receive and detect sensing results. In various embodiments, the UE receives and detects sensing results based on system information (SI) that it may receive from another wireless communication node / device (e.g., another UE, a base station). In some example scenarios, a UE that may receive and detect sensing results in a sensing window (e.g., a sensing window for SL_PRS, a sensing window for data) receives SI from a second UE, and the sidelink PRS is transmitted to the second UE. In various embodiments, the SI includes parameters associated with a second time window (e.g., a selection window) (e.g., defining the parameter), and the UE may transmit one or more sidelink PRSs within the second time window. For example, in various embodiments, the SI may include at least one of the parameters discussed in Section IX.

[0102] exist Figure 3 In the above, n refers to a certain duration in the configuration of data, or the first time slot after a certain duration in the configuration of data; n_PRS refers to a certain duration in the configuration of data, or the first time slot after a certain duration in the configuration of data.

[0103] Figure 3 Further illustrated is the transmission of one or more sidelink PRSs to the second UE, and in various embodiments, the transmission of the one or more sidelink PRSs occurs in time later than the reception and detection of sensing results during a sensing window of the SL_PRS and based thereon. In various embodiments, the transmission of the one or more sidelink PRSs occurs during a second time window (e.g., a selection window) that is later in time than the sensing window. In various embodiments, the transmission of the one or more sidelink PRSs is based on the SCI_PRS or control information associated with the SL_PRS, such as Figure 3 As shown. For example, the SCI_PRS can specify the time (e.g., within a selection window) to transmit one or more sidelink PRSs. In some examples, the SCI_PRS can specify additional aspects of the (multiple) sidelink PRS transmissions, such as specific resource blocks used for the sidelink PRSs.

[0104] In various embodiments, the SCI_PRS may be periodically received by the UE from another wireless communication device / node (e.g., a base station, another UE). In various embodiments, the UE transmits one or more sidelink PRSs to a second UE, and the UE receives SI and / or SCI_PRS from the second UE.

[0105] In various embodiments, the selection window for the SL-PRS is associated with at least one of a PRS period for a transmitting user equipment (TX UE), a PRS priority of the TX UE.

[0106] In various embodiments, the selected resources in the selection window are based on the resources of the SCI / control information of the SL_PRS in the sensing window for the SL-PRS.

[0107] In various embodiments, the selected resource in the selection window is independent of the SCI / control information for the sidelink data in the sensing window for the data;

[0108] In various embodiments, the sensing window for the SL-PRS is associated with at least one of: one or more PRS periods for a receiving user equipment (RX UE), one or more PRS priorities for the RX UE, a PRS SCS for an RS UE, a PRS duration, or a number of PRS configurations.

[0109] In various embodiments, the sensing / selection window for sidelink data is compared with the sensing / selection window for SL-PRS. For example, if the sensing / selection window for data is lower than the sensing / selection window for SL-PRS, the start time of the sensing / selection window for SL-PRS is later / earlier / prior to the sensing / selection window for data, or the end time of the sensing / selection window for SL-PRS is later / earlier / prior to the sensing / selection window for data.

[0117] The data configuration is indicated by SCI.

[0118] The priority of the independent PRS and the PRS configuration is indicated by the SCI, or the data configuration is indicated by the SCI.

[0119] · If the priority is indicated by the SCI of the independent PRS or the PRS configuration, use the priority

[0120] value to determine the priority;

[0121] · If the priority is indicated by the SCI of the PRS configuration, the independent PRS has the lowest / highest priority;

[0122] · The SCI of the independent PRS or the PRS configuration has no priority indication; the independent PRS has the lowest / highest priority; the SCI of the PRS configuration has the lowest / highest priority, and the SCI of the PRS configuration has the same priority as the associated data configuration. For example: independent PRS priority > data configuration priority; independent PRS priority < data configuration priority; independent PRS priority > priority of the SCI of the PRS configuration; independent PRS priority < priority of the SCI of the PRS configuration; data configuration priority > priority of the SCI of the PRS configuration; data configuration priority < priority of the SCI of the PRS configuration.
