[0033] The technical solutions provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.
[0034] like Figure 2 As shown, a positioning method 200 on an SL is provided as an exemplary embodiment of this application. The method can be executed by a first terminal, specifically by software and / or hardware installed in the first terminal. The method may include the following steps.
[0035] S210, send the first signal according to the first information.
[0036] The first information may be configured by a terminal (such as a first terminal, a second terminal, etc.) or a network-side device, or it may be specified by a protocol. This embodiment does not impose any restrictions on this.
[0037] In addition, the first information may include at least one of the following (1)-(3).
[0038] (1) The first priority information corresponding to the first signal. The first priority information may include, but is not limited to, priority type, priority indication information, etc. The specific content of the first priority information can be set according to the requirements, and this embodiment does not impose any restrictions.
[0039] (2) The first configuration information corresponding to the first signal. The first configuration information may include resource information, periodic information, terminal identification information, time domain information, frequency domain information, power information, spatial information, etc. involved in sending the first signal. This embodiment does not impose any limitations on this.
[0040] (3) The quality of the first channel corresponding to the first signal. The quality of the first channel can be characterized by parameters such as, but not limited to, Reference Signal Received Power (RSRP), Signal-to-noise ratio (SNR), Signal-to-noise and interference ratio (SINR), Channel Occupancy Ratio (CR), and Channel Busy Ratio (CBR).
[0041] Accordingly, the implementation process of S210 varies depending on the first information. For example, if the first information includes the first priority information corresponding to the first signal, then the aforementioned sending of the first signal according to the first information may include: sending the first signal according to the first priority information corresponding to the signal.
[0042] For example, assuming the first information includes the first priority information corresponding to the first signal and the first configuration information corresponding to the first signal, then the aforementioned sending of the first signal according to the first information may include: sending the first signal according to the first priority information corresponding to the signal and the first configuration information corresponding to the first signal.
[0043] It is understood that when the first information includes other information, such as the first channel quality, the implementation process of S210 can refer to the foregoing description, and will not be repeated here.
[0044] In addition, when the first terminal sends the first signal, it can use multicast, broadcast or unicast to send it in order to realize the positioning of the terminal (such as the first terminal, the second terminal, etc.), such as absolute position positioning or relative position positioning, so as to adapt to the terminal positioning services involved in V2X services.
[0045] Furthermore, in one implementation, the first signal may include an SL reference signal and / or a UU port uplink reference signal to achieve terminal positioning as described in at least one of (1)-(4) below.
[0046] (1) Determine the location of the first terminal.
[0047] (2) Determine the relative position between the first terminal and at least one second terminal.
[0048] (3) Determine the location of at least one second terminal.
[0049] (4) Determine the distance between the first terminal and at least one second terminal.
[0050] It is understood that, among the aforementioned four items, terminal positioning can be achieved by the second terminal that receives the first signal or by the first terminal that sends the first signal. This embodiment does not impose any restrictions on this.
[0051] Furthermore, in this embodiment, the terms "first" and "second" in "first terminal" and "second terminal" are only used for distinction and have no actual meaning. For example, depending on the positioning scenario, the first terminal can be used to transmit the first signal, receive and measure the first signal, or be a scheduling terminal for scheduling the first terminal to transmit the first signal or scheduling the second terminal to receive the first signal. It should be noted that, in addition to the aforementioned first terminal serving as the terminal for transmitting the first signal and the second terminal serving as the terminal for measuring the first signal, in some implementations, there are also terminals that are both the first terminal and the second terminal. In this case, "first terminal" and "second terminal" are functional descriptions.
[0052] In the foregoing embodiments, the first terminal sends a first signal for terminal positioning based on the first information. The first signal includes at least one of the following: first priority information corresponding to the first signal; first configuration information corresponding to the first signal; and first channel quality corresponding to the first signal. Thus, terminal positioning on SL can be realized, while adapting to the terminal positioning service requirements in V2X scenarios.
[0053] like Figure 3As shown, a positioning method 300 on an SL is provided as an exemplary embodiment of this application. The method can be executed by a first terminal, specifically by software and / or hardware installed in the first terminal. The method 300 may include the following steps.
[0054] S310, send the first signal according to the first information.
[0055] In addition to referring to the relevant descriptions in the aforementioned method embodiments, the implementation process of S310 in this embodiment may be as follows: the first information may be determined by at least one of the following (1)-(3).
[0056] (1) Receive higher-layer signaling; the higher-layer signaling may be Radio Resource Control (RRC) signaling, LTE Positioning Protocol (LPP) signaling, etc. For example, the first terminal can obtain the first information by parsing the received higher-layer signaling.
[0057] (2) Receive a first target SCI, wherein the first target SCI includes a Level 1 SCI and / or a Level 2 SCI.
[0058] (3) Monitoring channel quality. For example, the first terminal obtains first information by monitoring channel quality.
[0059] As another implementation, the first information may include at least one of the following (1)-(3).
[0060] (1) The first priority information corresponding to the first signal.
[0061] Wherein, when the first priority information includes priority indication information and / or priority type information, the implementation process of the priority indication information and the priority type information can be referred to the following description.
[0062] 1. The priority type information may include at least one of transmission priority, measurement priority, and collision priority.
[0063] The transmission priority refers to whether to send the first signal first when there are other signals or data to be sent, or whether to send the first signal under different circumstances, such as when the channel quality is good, or when the priority is low but there is no other data to be sent. The measurement priority refers to whether to measure the first signal first when there are multiple signals to be measured, or whether to measure the first signal under different circumstances, such as when the priority is higher or lower than a certain threshold. The collision priority refers to how the first signal is processed when it collides with other signals or channels in terms of resources (such as time domain, frequency domain, spatial domain, etc.).
[0064] 2. The priority indication information includes at least one of the following (a)-(e).
[0065] (a) First indication information, the first indication information is used to indicate that the priority of the first signal is a predetermined priority, the predetermined priority includes N values, each of which represents a different priority.
[0066] In one implementation, assuming the predetermined priority includes three values: a first priority, a second priority, and a third priority, then the first indication information can be used to indicate that the priority of the first signal is the first priority, the second priority, or the third priority.
[0067] In another implementation, the priority indicator is log2(N) bits, such as 3 bits, indicating 8 priorities. For example, 000 is the first priority, 001 is the second priority, and so on.
[0068] In one implementation, the first indication information may also be part of the configuration information of the first signal described below, and this is not limited thereto.
[0069] (b) Second indication information, which indicates the priority of the first signal associated with a designated data channel. The designated data channel may include channels corresponding to the UU port and / or SL, such as SCI, Physical SideLink Control Channel (PSCCH), Physical SideLink Shared Channel (PSSCH), Physical Downlink Control Channel (PDCCH), control resource set (Coreset), etc., which are not limited in this embodiment.
[0070] In one implementation, if the second indication information indicates that the priority of the first signal is associated with a designated data channel, it can be determined that the first signal and the designated data channel have the same priority.
[0071] For example, the second indication information indicates that the first signal is associated with an SCI, and its priority is determined by the priority of the SCI. Another example is that the second indication information indicates multiple priorities, with the SCI selecting the corresponding priority. Yet another example is that the first configuration information of the first signal includes the association information, indicating that the priority of the first signal is associated with a specified data channel, such as PSSCH or PSCCH.
[0072] (c) Third indication information, the third indication information is used to indicate the priority of the first signal associated with a specified reference signal, the specified reference signal may include a UU port uplink reference signal or an SL reference signal, such as a synchronization signal and PBCH block (SSB), a CSI reference signal (CSI-RS), a demodulation reference signal (DMRS), a phase-tracking reference signal (PTRS), a sounding reference signal (SRS), a position reference signal (PRS), etc.
[0073] In one implementation, when the third indication information indicates that the priority of the first signal is associated with a designated reference signal, the first signal has the same priority as the UU port uplink reference signal or the SL reference signal. For example, the third indication information indicates that the first signal is associated with a certain SSB, and its priority is determined by the priority of the corresponding SSB. As another example, the first configuration information of the first signal includes the association information, indicating that the priority of the first signal is associated with a designated signal.
[0074] (d) Priority information of the target location request, wherein the target location request is used to request the first terminal to perform a location operation.
[0075] In one implementation, the first signal has the same priority as the target location request.
[0076] In another implementation, priority information is included in the target location request information, and the related operations triggered by the target request have the same priority, such as sending the first signal or measuring the first signal. It is worth noting that the request to the first terminal to perform a location operation includes, but is not limited to, sending the first location signal, receiving the first information, or sending the second information, at least one of these.
[0077] (e) Priority information of the target signal request, wherein the target signal request is used to request the first terminal to send the first signal.
[0078] In one implementation, the first signal and the target signal request have the same priority.
[0079] (2) The first configuration information corresponding to the first signal.
[0080] The first configuration information may include at least one of the following (a)-(g).
[0081] (a) First resource information.
[0082] The first resource information can be used to indicate the frequency domain resources used to transmit the first signal. In this embodiment, the first resource information may include at least one of the following: frequency layer information, carrier information, bandwidth portion (BWP) information, resource pool information, transmission channel information, aggregation information, frequency domain offset, comb size, starting resource position in the Physical Resource Block (PRB), and bandwidth in the PRB.
[0083] In one embodiment, the frequency layer information can be a collection of the same information, such as including but not limited to at least one of the following: comb size, frequency domain granularity, cyclic prefix (CP) type, frequency domain common starting point (pointA), subcarrier spacing (SCS), etc.
[0084] The carrier information may include, but is not limited to, at least one of the following: carrier ID, frequency domain granularity, CP type, frequency domain common starting point, subcarrier spacing, etc.
[0085] The Bandwidth Part (BWP) information may include, but is not limited to, at least one of the following: BWPID, SL configuration information, Sounding Reference Signal (SRS) configuration information, etc.
[0086] The resource pool configuration information may include, but is not limited to, at least one of the following: resource pool ID, transmission channel configuration information, SL synchronization information, SL starting resource block (RB) information, SL time information, SL signal information, SL window information, SL power information, etc.
[0087] The aggregation information may include, but is not limited to, at least one of the following: multiple carriers, multiple BWPs, multiple frequency layers, multiple transmission channels, aggregation indication information, etc.
[0088] (b) First period information.
[0089] The first period information is used to indicate the period information of the first signal.
[0090] In one implementation, the first periodic information may include at least one of a periodic value set, a silent parameter set, and a repetition index set. For example, the periodic value set may include slots 1, 2, 4, 5, 8…, as shown in Table 1.
[0091] Table 1
[0092] sl1 NULL sl2 INTEGER(0..1) sl4 INTEGER(0..3) sl5 INTEGER(0..4) sl8 INTEGER(0..7) sl10 INTEGER(0..9) …… ……
[0093] The first period information can be a value from the set of period values shown in Table 1 above, such as specifying a period as sl1, which has a period of 1 slot, or specifying a period as sl2, which has a period of 2 slots, and so on.
[0094] The set of silence parameters can indicate the period or repetition of the silence, and can be 1, 2, 3, 4, 6, or 8 bits. For example, 8 bits, such as 00000001, indicates that a cycle is sent every 8 cycles.
[0095] The set of repetition indices indicates the number of repetitions. For example, if one SRS is sent every period, the repetition indicator is 0011, meaning there are four repetition indices, but only the first and second repetition indices are sent.
[0096] (c) Terminal identification information.
[0097] The terminal identification information may include the identification information of the first terminal and / or the identification information of the second terminal, wherein the second terminal is the terminal to be measured.
[0098] In one implementation, the identification information of the first terminal can be any one of the following: identification information of all first terminals in the cell to which the first terminal belongs, common identification information of the first terminals in the cell to which the first terminal belongs, or identification information of all first terminals under the first beam to which the first terminal belongs or under the second beam adjacent to the first beam.
[0099] It is understood that, similar to the identification information of the first terminal, the identification information of the second terminal can also be any of the following: the identification information of all second terminals in the cell to which the second terminal belongs, the common identification information of the second terminals in the cell to which the second terminal belongs, or the identification information of all second terminals under the first beam to which the second terminal belongs or under the second beam adjacent to the first beam.
[0100] (d) First time domain information.
[0101] The first time-domain information includes at least one of the following: subframe offset, synchronization offset, time slot offset, symbol offset, and number of symbols corresponding to the first signal. It is worth noting that the aforementioned offset can be relative to any one of SLSFN0, uu SFN0, BWP start position, transmission channel start position, resource pool start position, SCI position, and DCI position.
[0102] (f) First power information.
[0103] The first power information may include at least one of the following: p0 power value, path loss coefficient, and maximum transmit power of the serving cell corresponding to the first terminal.
[0104] In one implementation, when the first signal includes a UU port uplink reference signal, the first power information may include at least one of the following: the p0 power value on the UU port, the path loss coefficient, the path loss reference signal, and the maximum transmit power of the serving cell corresponding to the first terminal.
[0105] In another implementation, when the first signal includes an SL reference signal, the first power information may include at least one of the following: the p0 power value on the SL, the path loss coefficient, the path loss reference signal, and the maximum transmit power of the serving cell corresponding to the first terminal.
[0106] In the above implementation, the uplink reference signal of the UU port or the reference signal of the SL port can share the same configuration, such as the reference signal of the SL port or the reference signal of the UU port. It is worth noting that the path loss reference signal can also be the path loss reference signal of the SL port or the path loss reference signal of the UU port, or the UU port can only be the path loss reference signal of the UU port, and the SL port can only be the path loss reference signal of the SL port; there are no restrictions here.
[0107] (g) First spatial information.
[0108] The first spatial information includes the spatial relationship between the first signal and a designated signal or a designated channel. For example, the first signal and the designated channel or the designated channel have the same spatial relationship.
[0109] It should be noted that in the preceding (a)-(g), the specified signal can be the signal corresponding to the UU port and / or SL, such as at least one of SCI, SSB, CSI-RS, DMRS, PTRS, SRS, and PRS.
[0110] The designated channel is the channel corresponding to the UU port and / or SL, such as at least one of PSCCH, PSSCH, PDCCH, and Coreset.
[0111] (3) The first channel quality corresponding to the first signal.
[0112] Regarding the first channel quality in (3), please refer to the relevant description in the foregoing embodiments. To avoid repetition, it will not be repeated here.
[0113] It is understood that the first information may include some or all of the contents in (1)-(3) above, and the specific content may be set according to actual needs. This embodiment does not limit this.
[0114] Based on the description of the first information above, if the first information includes the first priority information corresponding to the first signal, or if the first terminal can determine the priority value of the first signal according to the first priority information, then in this case, sending the first signal according to the first information in the above S310 may include any one of the following (1)-(3).
[0115] (1) If the priority value of the first signal is less than the first priority threshold, the first signal shall be sent; otherwise, the first signal may not be sent.
[0116] (2) If the priority value of the first signal is less than the second priority threshold and the priority of the signal or channel that collides with it is greater than the third priority threshold, the first signal shall be sent; otherwise, the first signal may not be sent.
[0117] (3) If the priority value of the first signal is less than the priority value of the signal or channel that it collides with, the first signal shall be sent; otherwise, the first signal may not be sent.
[0118] It should be noted that the signals or channels that collide with the first signal as described in (2) and (3) above can refer to the relevant descriptions of the specified signals and specified channels mentioned above. To avoid repetition, they will not be repeated here. In addition, the first priority threshold, the second priority threshold, and the third priority threshold mentioned above can be configured by the terminal (such as the first terminal or the second terminal, etc.), or by the network-side device, or can be specified by the protocol. This embodiment does not impose any restrictions on this.
[0119] In this embodiment, by further refining the configuration of the first information and then sending the first signal based on the first information, it is possible to further adapt to different positioning requirements under V2X and ensure the accuracy of the positioning results.
[0120] like Figure 4 As shown, a positioning method 400 on an SL is provided as an exemplary embodiment of this application. The method 400 can be executed by a first terminal, specifically by software and / or hardware installed in the first terminal. The method 400 may include the following steps.
