[0001] This disclosure relates to a method for use in a terminal device.

[0002] This disclosure also relates to an apparatus for a terminal device. Summary of the Invention

[0003] An exemplary embodiment relates to a method for a terminal device, such as a computer-implemented method, comprising: providing first information characterizing a mapping of at least one Quality of Service (QoS) related parameter of sidelink-based positioning to a corresponding priority, and optionally using the first information. In some embodiments, this can facilitate the coordination of resources used for sidelink-based positioning, for example, with resources that can be used to transmit data via the sidelink.

[0004] In some embodiments, aspects of sidelink-based positioning may include, for example, one or more of the following: a) ranging, and / or b) relative positioning, c) absolute positioning.

[0005] In some embodiments, the terminal device may be, for example, a user equipment (UE) or a data transceiver modem, which may be associated with a moving object such as a vehicle, such as a car or truck.

[0006] In some exemplary embodiments, the terminal device may be at least one of the following (or may be associated with at least one of the following, for example): IoT (Internet of Things) device, infrastructure component or part of infrastructure component (e.g., traffic light, street light, traffic sign, toll station), industrial automation component such as IIoT (Industrial IoT) component or infrastructure (e.g., robot, machine, etc.), mobile broadband user device and / or vehicle.

[0007] In some exemplary embodiments, the terminal device is based on and / or at least partially complies with at least one 3GPP radio standard, such as 4G (fourth generation), 5G (fifth generation), 6G (sixth generation) or other radio access technologies.

[0008] In some embodiments, the terminal device may be used, for example, in conjunction with at least one other terminal device, for a sidelink-based positioning process, which may include transmitting associated signaling to the other terminal device via at least one sidelink interface. In some embodiments, in addition to the signaling transmission associated with the sidelink-based positioning process, data transmission may also be performed to the other terminal device via at least one sidelink interface.

[0009] In some embodiments, a shared resource pool is provided for sidelink transmission, which can lead to conflicts between resources used for transmitting signaling associated with a sidelink-based positioning process and resources used for data transmission in some conventional methods. In some embodiments, the principles of the embodiments enable the avoidance or resolution of such conflicts.

[0010] In some embodiments, two or more resource pools may be provided, for example for sidelink transmission, and may be configured for at least one of the following: a) data, b) sidelink positioning protocol (SLPP), and c) positioning signals.

[0011] In some embodiments, using the first information includes at least one of the following: a) evaluating the priority associated with at least one QoS-related parameter of the sidelink-based location relative to the priority associated with the data to be transmitted on the sidelink, and / or b) comparing the priority associated with at least one QoS-related parameter of the sidelink-based location with the priority associated with the data to be transmitted on the sidelink.

[0012] In some embodiments, the method includes: transmitting information associated with side-link-based positioning via a side link based on first information.

[0013] In some embodiments, the method includes at least one of the following: a) organizing first information in tabular form, and / or b) assigning a corresponding priority to at least one QoS-related parameter.

[0014] In some embodiments, the method includes assigning a resource type to at least one QoS-related parameter, such as indicating at least one QoS-related parameter a) a resource type related to signaling and / or b) a resource type not related to data.

[0015] In some embodiments, the method includes providing information elements that characterize the accuracy (e.g., desired accuracy) associated with sidelink-based positioning.

[0016] In some embodiments, the method includes at least one of the following: a) processing a first QoS-related rule associated with data, such as in a vehicle-to-everything (V2X) layer; b) processing a second QoS-related rule associated with sidelink-based positioning, such as in a vehicle-to-everything (V2X) layer; and c) processing a third QoS-related rule common to both data and sidelink-based positioning.

[0017] In some embodiments, the method includes at least one of the following: a) mapping information to be transmitted associated with side-link-based positioning to at least one bearer based on first information, for example using a layer 2 process, and / or b) mapping information to be transmitted associated with data to at least one bearer based on priority associated with data.

[0018] In some embodiments, the method includes at least one of the following: a) mapping to at least one bearer QoS information (e.g., priority) associated with sidelink-based location based on first information, for example using a layer 2 process, and / or b) mapping to at least one bearer data-associated information to be transmitted based on the to-be-transmitted QoS information (e.g., priority associated with data).

[0019] In some embodiments, the method includes: providing a rule comprising a plurality of entries, for example organized into a table, wherein a first number of entries characterize the priority of a data-related service, and wherein a second number of entries characterize the priority associated with a sidelink-based location.

[0020] In some embodiments, one or more entries in the table represent identifiers, such as IDs, which in some embodiments include the QoS of the data and can be extended in some embodiments, for example, to include IDs that identify location requests or overlapping indications of location requests.

[0021] In some embodiments, a priority, such as that represented by a PQI value according to some planned and / or accepted criteria, may include 8 bits, wherein in some embodiments, 6 bits are used, for example for the current QoS ID, and 2 reserved bits are used.

[0022] In some embodiments, one or more values ​​within 6 bits of the PQI value can be defined, for example, for positioning only. In other words, one or more values ​​represented by the 6 bits of the PQI value can be defined as priority values ​​used only in relation to positioning.

[0023] Therefore, some embodiments involve using one or more values, represented by 6 bits of the PQI value, as priority values ​​associated with the location.

[0024] In some embodiments, the ID may be extended to, for example, 8 bits to provide further priority values, which in some embodiments may be used, for example, for positioning, to indicate a priority value associated with positioning.

[0025] Therefore, some embodiments involve using an 8-bit ID, for example by extending the ID associated with the PQI, to provide additional priority values ​​that can be used for location, and optionally, at least some of the additional priority values ​​are used for location.

[0026] In some embodiments, at least one of the last two bits of the eight PQI bits may be used, for example, to explicitly indicate a PQI value associated with a location. In other words, in some embodiments, the PQI may use six bits (e.g., currently, according to some planned and / or accepted standards), and one of the reserved bits may be used according to indications proposed in some embodiments (e.g., for explicitly indicating a PQI value associated with a location).

[0027] Therefore, some embodiments involve using at least one of, for example, eight PQI bits to indicate (e.g., explicitly indicate) a priority value associated with the location, such as a PQI value.

[0028] In some embodiments, the method includes: providing a first rule, such as organized as a first table, including entries representing priorities of data-related services; and providing additional rules, such as organized as at least one additional table, including entries representing priorities associated with at least one aspect of sidelink-based positioning.

[0029] A further exemplary embodiment relates to an apparatus for a terminal device, wherein the apparatus is configured to perform the method according to the embodiment.

[0033] Further exemplary embodiments relate to a computer-readable storage medium including instructions that, when executed by a computer, cause the computer to perform a method according to an embodiment.

[0034] Further exemplary embodiments relate to a data carrier signal that carries and / or represents a computer program according to an embodiment.

[0035] Further exemplary embodiments relate to the use of methods and / or apparatuses and / or terminal devices and / or communication systems and / or computer programs and / or computer-readable storage media and / or data carrier signals according to embodiments for at least one of the following: a) mapping at least one Quality of Service (QoS) related parameter of sidelink-based location (e.g., signaling associated with sidelink-based location) to a corresponding priority; b) comparing the priority associated with at least one QoS related parameter of sidelink-based location with the priority associated with data; c) avoiding resource conflicts, e.g., conflicts between signaling and data in sidelink-based location; d) using priority and / or QoS information, e.g., priorities of the same type, for coordinating resource usage associated with sidelink transmissions, which are for data and signaling in sidelink-based location; e) resolving, for example, resource conflicts between signaling and data in sidelink-based location.

Detailed Implementation

[0037] See Figure 1 , 2 An exemplary embodiment relates to a terminal device 10 ( Figure 2 A method, such as a computer-implemented method, includes: providing 100 first information I-1, which characterizes at least one QoS-related parameter PARAM-QoS mapping MAP of a sidelink-based location SL-POS (e.g., for signaling associated with the sidelink-based location SL-POS) to a corresponding priority PRIO, and optionally, using 102 first information. In some embodiments, this can facilitate the coordination of resources for the sidelink-based location SL-POS, for example, with resources that can be used to transmit data via the sidelink.

[0038] In some embodiments, at least some, such as all, aspects of the method according to the embodiments may be performed by the apparatus 200.

[0039] In some embodiments, Figure 2 Terminal device 10 may be, for example, a user equipment (UE) or a data transceiver modem, which may be associated with a mobile object, such as a vehicle, such as a car or truck (not shown). In some embodiments, this may also apply to another terminal device 10a.

[0040] In some exemplary embodiments, Figure 2 Terminal device 10 may be at least one of the following (or may be associated with at least one of the following, for example): IoT (Internet of Things) device, infrastructure component or part of infrastructure component (e.g., traffic light, street light, traffic sign, toll station), industrial automation component, such as IIoT (Industrial IoT) component or infrastructure (e.g., robot, machine, etc.), mobile broadband user device and / or vehicle. In some embodiments, this may also apply to additional terminal device 10a.

[0041] In some exemplary embodiments, Figure 2 Terminal device 10 is based on and / or at least partially complies with at least one 3GPP radio standard, such as 4G (fourth generation), 5G (fifth generation), 6G (sixth generation) or other radio access technologies, and can be used, for example, with a corresponding communication system 1000. In some embodiments, this may also apply to another terminal device 10a.

[0042] In some embodiments, Figure 2 Terminal device 10 may be used, for example, together with at least one other terminal device 10a for a sidelink-based positioning process SL-POS, which may include, for example, transmitting relevant signaling to the other terminal device 10a via at least one sidelink interface IF-SL (e.g., PC5 type).

[0043] In some embodiments, for example, in addition to the transmission of signaling and / or other information associated with the sidelink-based positioning process SL-POS, data exchange DAT-EX, such as transmission and / or reception, can also be performed to another terminal device 10a via at least one sidelink interface IF-SL.

[0044] In some embodiments, Figure 2 A shared resource pool (RES-POOL) is provided for sidelink information exchange, such as transmissions, where resource conflicts can occur in some conventional methods for signaling transmissions associated with the sidelink-based positioning process (SL-POS) and for data transmissions, such as data exchange (DAT-EX). In some embodiments, such conflicts can be avoided and / or resolved according to the principles of the embodiments.

[0045] In some embodiments, Figure 1 The first information I-1 using 102 includes at least one of the following: a) evaluating 102a with respect to the priority PRIO-DAT associated with at least one QoS-related parameter PARAM-QoS (e.g., for) sidelink-based positioning SL-POS, relative to the priority PRIO-DAT associated with the data DAT-SL to be transmitted on the sidelink. Figure 2 (a) and / or (b) compare the priority PRIO associated with at least one QoS-related parameter PARAM-QoS of the sidelink-based positioning SL-POS with the priority PRIO-DAT associated with the data DAL-SL to be transmitted on the sidelink 102b.

[0046] In some embodiments, Figure 1 The method includes: based on first information I-1, sending information SL-POS-INF associated with side-link-based positioning SL-POS to, for example, another terminal device 10a on a side link.

[0047] In some embodiments, Figure 1The method includes at least one of the following: a) organizing 100a first information I-1 in tabular form, for example, and / or b) assigning a corresponding priority PRIO to 100b to at least one QoS-related parameter PARAM-QoS. In some embodiments, at least one of organizing 100a and / or assigning 100b may be performed in providing block 100. Note that in some other embodiments, the first information I-1 may be organized in a form other than the tabular form exemplarily mentioned.

[0048] In some embodiments, Figure 3 The method includes: inputting at least one QoS-related parameter PARAM-QoS ( Figure 2 Assign 110 resource type RES-TYPE, for example, indicating at least one QoS-related parameter a) a resource type related to signaling and / or b) not related to data.

[0049] In some embodiments, Figure 3 The method includes providing 112 information elements IE-PREC, which characterize the accuracy associated with side-link-based positioning SL-POS.

[0050] In some embodiments, Figure 4 The method includes at least one of the following: a) processing 120 with data DAT-SL ( Figure 2 The first QoS-related rule associated with this is QoS-RUL-1, for example, in the vehicle-to-everything V2X layer (see...). Figure 11 element E2), b) process 122 ( Figure 4 The second QoS-related rule QoS-RUL-2 associated with sidelink-based location SL-POS, for example in the vehicle-to-everything V2X layer (see Figure 11 The elements E2), c) process 124 for data DAT-SL and side-link based positioning SL-POS common third QoS related rule QoS-RUL-3.

[0051] In some embodiments, at least one of QoS-RUL-1, QoS-RUL-2, and QoS-RUL-3 includes at least one rule. In other words, in some embodiments, for example, it is possible for the first QoS-related rule QoS-RUL-1 to include, for example, a single rule, i.e., the opposite of multiple rules. In some embodiments, this may also apply to other types of rules QoS-RUL-2, QoS-RUL-3.

[0052] In some embodiments, Figure 5The method includes at least one of the following: a) mapping information to be transmitted associated with a side-link-based location SL-POS to at least one bearer BEAR-SL-POS, for example using a layer 2 process, based on first information I-1, and / or b) mapping information to be transmitted associated with data DAT-SL to at least one bearer BEAR-DATA, based on priority PRIO-DAT associated with data DAT-SL.

[0053] In some embodiments, Figure 6 , Figure 7 The method includes providing 140 rules, for example organized as a table TAB-1, including multiple entries e1, e2, ..., ek, ... eN, wherein a first number of N-1 entries e1, e2, ... represent priorities of data-related services (e.g., associated with data transmission on a sidelink), and wherein a second number of N-2 entries ek, ..., eN represent priorities associated with a sidelink-based location SL-POS. In some embodiments, this enables the evaluation of priorities associated with a sidelink-based location SL-POS and a sidelink-based data transmission DAT-SL, for example, comparing these priorities, for example, to avoid and / or resolve resource conflicts, such as a shared resource pool RES-POOL that can be provided for sidelink transmissions in some embodiments. Figure 2 Resource conflicts. Figure 6 The optional box 142 indicates the use of table TAB-1, for example, for evaluation, such as comparison.

[0054] As an example, Figure 7 The first entry e1 of table TAB-1 characterizes a relationship between a priority (e.g., represented by a PQI value) provided in column col_1, for example, in the form of a priority value v1, and one or more attributes (e.g., QoS requirements associated with the priority, such as for a particular data-related service). Therefore, in some embodiments, column col_3 may include, for example, a corresponding value v1a of the QoS parameter (e.g., delay budget) of the data-related service characterized by entry e1. In some embodiments, a resource type (e.g., "data", such as with a guaranteed bit rate, GBR, or "non-data") may be specified in the second column col_2.

[0055] In some embodiments, the PQI value is a specific 5QI, such as a 5G QoS identifier, as defined in clause 5.7.2.1 of 3GPP TS 23.501. Therefore, in some embodiments, the PQI value can be used to characterize priority PRIO and PRIO-DAT. However, in some other embodiments, at least one other value or type of value can be used to characterize priority PRIO and PRIO-DAT, respectively. In some embodiments, the information content of a particular column, such as that characterizing a specific QoS parameter, can be interpreted based on whether the corresponding entry (e.g., row) in table TAB-1 relates to a data-related service or to location. As an example, if entry e1 relates to data, the content of the column characterizing the specific QoS parameter can be interpreted as, for example, "Not Available (NA)," while if another entry ek relates to location, the content of the same column characterizing the specific QoS parameter can be interpreted as a precision value.

[0056] In some embodiments, more or fewer columns may be provided than those exemplarily described.

[0057] As another example, Figure 7 The second entry e2 of table TAB-1 can also characterize the relationship between, for example, the priority provided in column col_1 (e.g., in the form of priority value v2) and, for example, one or more attributes (e.g., QoS requirements associated with the priority), for a particular (other) data-related service, such as a service different from the one associated with entry e1. Therefore, in some embodiments, column col_3 may, for example, include the corresponding value v2a of the QoS parameter of the data-related service characterized by entry e2.

[0058] In some embodiments, further entries... may be provided in a first number of N-1 entries, for example, representing a further relationship between priority and associated QoS parameters, for example, for further data-related services.

[0059] As another example, Figure 7 The k-th entry ek of table TAB-1 represents the relationship between, for example, a priority provided in column col_1 (e.g., in the form of a priority value v3) and, for example, one or more attributes (e.g., QoS requirements associated with the priority), such as a specific aspect of sidelink-based positioning. Therefore, in some embodiments, column col_3 may, for example, include the corresponding value v3a of the QoS parameter for the specific aspect of sidelink-based positioning represented by entry ek. A similar observation applies to other entries eN of table TAB-1, in relation to other values ​​v4, v4a, etc.

[0060] In some embodiments, aspects of sidelink-based positioning may include, for example, one or more of the following: a) ranging, and / or b) relative positioning, c) absolute positioning.

[0061] It can be seen that, Figure 7Table TAB-1 allows both aspects of data transmission with relevant priorities and aspects of location based on side links (e.g., signaling based on side links) with relevant priorities to be considered in the same table, thereby facilitating, for example, prioritizing the allocation of resources for both data and location aspects from a shared resource pool RESPOOL.

[0062] In some embodiments, Figure 8 The method includes: providing 150 first rules, for example organized as a first table TAB-1a, including entries representing the priority of data-related services; and providing 152 additional rules, for example organized as at least one additional table TAB-1b, TAB-1c, including entries representing the priority associated with at least one aspect of sidechain-based positioning.

[0063] As an example, Figure 9A Aspects of the organization information according to some embodiments are schematically depicted, for example in the form of a first table TAB-1a. In some embodiments, the first table TAB-1a enables the consideration of aspects of data transmission with associated priorities, but excludes, for example, aspects related to side-link-based positioning.

[0064] In some embodiments, the first table TAB-1a may include one or more columns, such as eight columns c-1, c-2, c-3, c-4, c-5, c-6, c-7, c-8 (or at least some of the eight columns explained exemplarily), wherein column c-1 is associated, for example, with a priority value; column c-2 is associated, for example, with a resource type; column c-3 is associated, for example, with a default priority level; column c-4 is associated, for example, with a packet delay budget; column c-5 is associated, for example, with a packet error rate; column c-6 is associated, for example, with a default maximum data burst size; and column c-7 is associated, for example, with a default average window. In some embodiments, an optional column c-8 may be provided, for example, to specify further information.

[0065] As an example, in some embodiments, for data-related services used for queuing between terminal devices 10, 10a, the first row r-1 of the first table TAB-1a may, for example, include the first information element ie-1 in the first column c-1, specifying a priority value, such as a PQI value, such as "21". The information element ie-2 in column c-2 and row 1 may, for example, specify a resource type, such as "GBR". The information element ie-3 in column c-3 and row 1 may, for example, specify a default priority level "3". The information element ie-4 in column c-4 and row 1 may, for example, specify a packet delay budget of 20 milliseconds (ms). The information element ie-5 in column c-5 and row 1 may, for example, specify a packet error rate of 10^(-4). The information element ie-6 in column c-6 and row 1 may, for example, specify "unavailable" or "undefined" for the entry in row r-1. The information element ie-7 in column c-7 and row 1 may, for example, specify a default average window of 2000 ms.

[0066] In some embodiments, the first table TAB-1a may include additional entries, such as rows r-2, ..., which are not described in detail for clarity.

[0067] In some embodiments, such as according to Figure 8 Box 152 may be provided exemplarily by Figure 9B The second table TAB-1b is depicted. In some embodiments, Figure 9B The second table, TAB-1b, allows for consideration of aspects related to side-link-based positioning (e.g., Side-Link Positioning Protocol (SLPP) transmissions), along with associated priorities.

[0068] In some embodiments, the second table TAB-1b may include two or more columns, such as six columns c-1, c-2, c-3, c-4, c-5, and c-6, wherein column c-1 is associated with, for example, a priority value (e.g., in the form of a PQI value), column c-2 is associated with, for example, a resource type, column c-3 is associated with, for example, a default priority level, column c-4 is associated with, for example, a packet delay budget, and column c-5 is associated with, for example, a packet error rate. In some embodiments, an optional column c-6 may be provided, for example, to specify further information.

[0069] As an example, in some embodiments, for SLPP transport-related services, the first row r-1 of the second table TAB-1b may, for example, include the first information element ie-10 in the first column c-1, specifying a priority value, such as a PQI value, such as "21". The information element ie-11 in column c-2 and row 1 may, for example, specify a resource type. The information element ie-12 in column c-3 and row 1 may, for example, specify a default priority level of "3". The information element ie-13 in column c-4 and row 1 may, for example, specify a packet delay budget of 100 milliseconds (ms). The information element ie-14 in column c-5 and row 1 may, for example, specify a packet error rate of 10^(-2).

[0070] In some embodiments, Figure 9B The second table TAB-1b may include additional entries, such as rows r-2, ..., which are not described in detail for clarity.

[0071] In some embodiments, such as according to Figure 8 Box 152 can provide another, for example, by Figure 9C An exemplary depiction of the third table TAB-1c. In some embodiments, Figure 9C The third table, TAB-1c, allows for consideration of aspects related to side-link-based ranging, along with associated priorities.

[0072] In some embodiments, Figure 9C The third table, TAB-1c, may include at least two columns, for example, six columns c-1, c-2, c-3, c-4, c-5, and c-6, wherein column c-1 is associated, for example, with a priority value (e.g., in the form of a PQI value), column c-2 is associated, for example, with a default priority level, column c-3 is associated, for example, with a location measurement wait time, column c-4 is associated, for example, with accuracy and / or confidence interval, and column c-5 is associated, for example, with precision. In some embodiments, an optional column c-6 may be provided, for example, to specify further information.

[0073] As an example, in some embodiments, for ranging, the first row r-1 of the third table TAB-1c may, for example, include the first information element ie-20 in the first column c-1, specifying a priority value, such as a PQI value, such as "21". The information element ie-21 in column c-2, row 1 may, for example, specify a default priority level, such as "3". The information element ie-22 in column c-3, row 1 may, for example, specify a positioning measurement wait time of, for example, 10 ms. The information element ie-23 in column c-4, row 1 may, for example, specify an accuracy of, for example, 1 m and / or a 95% confidence interval. The information element ie-24 in column c-5, row 1 may, for example, specify an accuracy of, for example, 0.3 m.

[0074] In some embodiments, Figure 9C The third table TAB-1c may include additional entries r-2, ..., which are not described in detail for clarity.

[0075] In some embodiments, one or more of tables TAB-1a, TAB-1b, and TAB-1c can be used, for example, to evaluate the priority of data-related services and / or location-related services, wherein resources for related sidelink transmissions, such as those from a shared resource pool RES-POOL, can be determined to avoid conflicts, and the priorities of different services can be considered, for example.

[0076] In some embodiments, regarding Figure 7 , 9A The information presented in the exemplary tables of 9B and 9C can be organized in any other form, such as in addition to tables, for example, in the form of rules and / or information associations, where, for example, the QoS-related parameters PARAM-QoS associated with side-link-based positioning SL-POS and the priorities PRIO and PRIO-DAT associated with data transmission DAT-SL can be considered, for example, evaluated.

[0077] As an example, in some embodiments, the principles of the embodiments can be used to enhance an existing table according to some planned and / or accepted standards, such as by adding additional entries to Table 5.4.4-1 of 3GPP TS 23.287, for example by adding additional entries to Table 5.4.4-1 of 3GPP TS 23.287. The planned and / or accepted standards include, for example, proposed and / or standardized PQI-to-QoS feature mappings, provided for example by Table 5.4.4-1 of 3GPP TS 23.287. The additional entries, for example, relate to the mapping of the QoS-related parameter PARAM-QoS of sidelink-based location SL-POS to the corresponding priority PRIO, for example, represented by the PQI value column (column 1) of the table.

[0078] As another example, although traditional Table 5.4.4-1 of 3GPP TS 23.287 may have already included, for example, the above-mentioned... Figure 7 The reference symbol N-1 exemplarily represents the first entry, such as a first number of N-1 entries e1, e2, ... representing the priority of data-related services (e.g., associated with data transmission on a sidelink), but it does not provide entries representing the priority associated with sidelink-based location SL-POS. In some embodiments, this aspect of entries representing the priority associated with sidelink-based location SL-POS can be added to conventional Table 5.4.4-1 of 3GPP TS 23.287, thereby enabling efficient evaluation of priorities associated with different types of QoS requirements or different types of transports (e.g., data-to-location).

[0079] In some embodiments, the method includes: using one or more values ​​of a priority indicator (e.g., a PQI value) for a location-related priority value, such as using one or more values ​​of a priority indicator (e.g., a PQI value) represented by multiple bits (e.g., 6 bits) for a location-related priority value.

Figure 2 ). Element E9 represents the mapping of QoS rules to the bearer.

[0096] In some embodiments, Layer 2 processing E6 may be provided, for example, by an SDAP (Service Data Adaptation Protocol) entity, such as by enhancing a traditional SDAP entity with functionality according to the embodiments.

[0097] In some embodiments, Figure 10 Layer 2 processing E6 may, for example, use the principles according to the embodiment, such as providing and / or evaluating first information 1-1, see, for example, element E8.

[0099] In some embodiments, Figure 11 The exemplary configuration may be implemented, for example, by device 100, for example, for terminal devices 10, 10a, for example, within terminal devices 10, 10a.

[0100] In some embodiments, the principles of the embodiments enable, for example, the extension of existing processing, such as mapping priorities to QoS parameters in the form of PQI (e.g., V2X PQI), for example, extending existing V2X PQI processing schemes, such as tables (e.g., Table 5.4.4-1 of 3GPP TS 23.287), such as including location QoS, and a corresponding mapping from location QoS to associated priorities (e.g., in the form of PQI values). In some embodiments, mappings of transport QoS (e.g., end-to-end, E2E, latency) and / or accuracy and / or precision requirements (e.g., characterizing the number of measurements and / or bandwidth used) can be provided, as well as, for example, an indication of how critical location is to the associated application.

[0101] In some embodiments, the principles of the embodiments can provide advantages in resolving potential resource conflicts between data and location signaling, for example, regarding shared resource pools (RESPOOL). Figure 2 ).

[0102] As mentioned above, for example, refer to Figure 7 In some embodiments, at least some of the data QoS and / or SLPP transport QoS and / or ranging QoS can be provided in the same, for example, single mapping scheme, such as in the form of a single table, such as a PQI table, see example Figure 7 The table.

[0103] As mentioned above, for example, refer to Figure 9A , 9B The exemplary table of 9C may provide two or more tables, for example, with the same PQI / priority, and / or with different PQI and / or priorities.

[0104] In some embodiments, at least some services, such as each service, have a mapping of data and location priority (e.g., PQI) to QoS. In some embodiments, location QoS may be associated with, for example, SLPP transmissions and / or ranging.

[0105] In some embodiments, for example, if two or more tables are used, see, for example Figure 9A , 9B In some embodiments, labels may be provided, such as to enable lower layers to know which group they are processing, if, for example, PQI values ​​are reused across tables. In some embodiments, labels may be provided implicitly (e.g., the lower layer detects the type of group) or explicitly.

[0106] In some embodiments, for example, if two or more tables are used, see, for example Figure 9A , 9B For the three values ​​or types—data, SLPP transmission, and location report—priority values ​​(e.g., PQI values) can be similar. In some other embodiments, the PQIs for different tables can be different.

[0107] In some embodiments, a higher layer may convey at least one of the following: a) priority of SL positioning and / or SLPP transmission, and / or b) remaining latency budget, and / or c) accuracy, and / or d) confidence interval, and / or e) precision, which in some embodiments may be used, for example, by a lower layer for setting mode settings associated with at least one of the following: A) position reference signal PRS, mode, and / or B) comb structure, and / or C) PRS frequency.

[0108] In some embodiments, such as those described in TS 23.287, §5.4.2.4, the range can also be used to locate QoS and can be sent, for example, along with PQI values.

[0109] In some embodiments, when sending a location request, the initiating entity may, for example, provide a PQI value representing the priority PRIO along with the location request (where such a request is specified, for example, by 3GPP TR 23.700, 6.13.2).

[0110] In some embodiments, priority PRIO ( Figure 2 () can be used, for example, for resource allocation.

[0111] In some embodiments, a single QoS may be considered for a service, which may include, for example, transport and location. In some embodiments, at least one priority, namely a Layer 1 (L1) priority, may include, for example, eight levels, and may be considered for, for example, at least one, for example some, for example each entry (which in some embodiments considers a single (e.g., comparable) priority for data and location). In some embodiments herein, “comparable” means that when mapped to an SL radio bearer, Layer 2 may be able to compare, for example, transport layer data request priorities and LCS location layer request priorities, and may, for example, map the corresponding requests to the same or different bearers.

[0112] In some embodiments, the mapping to the radio bearer can be done, for example, at the SDAP (Service Data Adaptation Protocol) layer or another L2 layer, taking into account the associated priority of each transmitted data and / or location LCS request.

[0113] In some embodiments, such as after mapping to a radio bearer, and if both data and transmissions are mapped to the same bearer, the L2 layer (e.g., MAC) can use the priority associated with each of the two different requests, for example, to prioritize the transmission of either of these requests, and / or associate the two requests together (e.g., in the same time slot / allocation), and / or, for example, drop and / or delay either of the two requests based on their priority levels.

[0114] In some other embodiments, two QoS entries may be specified for each service, for example, one for data transmission and one for location. In some embodiments, the specified priorities may be scaled equally (e.g., using a comparable 8-level scale) or differently (e.g., for location, "only" 4 priority values, while for data transmission, 8 priority values).

[0115] In some embodiments, Figure 11 The mapping to the radio bearer can be done in, for example, the SDAP layer or another L2 layer entity E6, taking into account the associated priority of each of the transmitted data and / or location (e.g., LCS) requests, where, for example, two different QoS flow rule entries can be filtered in the L2 layer (e.g., SDAP) entity E6.

[0116] In some embodiments, taking into account each transmitted data (see...) Figure 2 The element PRIO-DAT) and / or the location LCS request (see Figure 2Two different associated priorities of an element PRIO), for example, considering comparable priority mapping criteria, for example, an example of 4 positioning priority levels and 8 transmission priority levels, can be mapped to a radio bearer, for example, in the SDAP layer or another L2 layer E6: P1 positioning > P1, P2, P3 transmission, P2 positioning = P4, P3 positioning = P5, P4 positioning < P6, P7, and P8.

[0117] In some embodiments, further examples and / or rules may be given.

[0118] In some embodiments, for example, if one service (e.g., the second service "S2") follows another service (e.g., the first service "S1"), then a check of priorities and / or consideration of priorities, for example, at least in the resource allocation process, may be performed. For example, if the priorities for service S1 and service S2 are P1 and P2 respectively, and if at least one of these two services is a positioning request, then in some embodiments, the following may be applied: If there is channel congestion: If P2 > P1, then S2 can replace S1 If P2 < P1, then S2 can lower its priority.

[0119] Another exemplary embodiment, Figure 12 , relates to the use 300 of a method according to an embodiment and / or a device 200 according to an embodiment and / or a terminal device 10, 10a according to an embodiment and / or a communication system 1000 according to an embodiment and / or a computer program PRG, PRG' according to an embodiment and / or a computer-readable storage medium SM according to an embodiment and / or a data carrier signal DCS according to an embodiment for at least one of the following: a) mapping 301 at least one quality of service QoS-related parameter associated with sidelink-based positioning (e.g., signaling associated with sidelink-based positioning) to a corresponding priority, b) comparing 302 the priority PRIO associated with at least one QoS-related parameter PARAM-QoS of sidelink-based positioning with the priority PRIO-DAT associated with data DAT-SL, c) avoiding 303 resource conflicts, e.g., resource conflicts between signaling and data of sidelink-based positioning, d) using 304 priorities, e.g., the same type of priorities, for coordinating the resource usage associated with sidelink transmission of data and signaling of sidelink-based positioning, e) resolving 305 resource conflicts, e.g., resource conflicts between signaling and data of sidelink-based positioning.

[0120] In some embodiments, the principles of the embodiments enable the resolution or avoidance of resource conflicts, for example, by prioritizing location QoS settings solely through V2X applications in the sidelink.

[0121] As another example, in some embodiments... Figure 2 Terminal device 10 can receive ranging / SL positioning service requests, for example, as defined in some planned and / or accepted standards (e.g., 3GPP TR 23.700), wherein the ranging / SL positioning service request may, for example, specify the QoS required for the requested ranging / SL positioning service. In some embodiments, first information I-1 may be provided, which characterizes a mapping MAP from the QoS required for the requested ranging / SL positioning service (e.g., which may be characterized by the QoS-related parameter PARAM-QoS) to the corresponding priority PRIO (which may be characterized, for example, as a PQI value). Therefore, the QoS requirements of the ranging / SL positioning service request (e.g., in terms of priority) can be compared with other services (e.g., data-related or location-related).
