Description

Resource allocation method and communication device

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a method and a communications device for configuring resources.

Background

In the long term evolution (long term evolution, LTE) and fifth generation (5) ^Th In generation, 5G) communication systems, the location function is based on a location management function (location management function, LMF)Realized by the method. For example, in a downlink scenario, the terminal device measures the positioning reference signal (position reference signal, PRS) transmitted by the network device and reports the measured value of PRS-reference signal received power (reference signal received power, RSRP) to the LMF. The LMF determines the location of the terminal device based on the measurement.

Currently, the third generation partnership project (3 ^rd generation partnership project,3 GPP) protocol has defined the resource allocation of PRS, but the resource allocation of side-link (SL) -PRS is not discussed in detail. Therefore, how to reasonably configure the resources of the SL-PRS is a problem to be solved.

Fig. 1 is a schematic diagram of a suitable communication system 100 in accordance with an embodiment of the present application. As shown in fig. 1, communication system 100 includes a network device 110, a terminal device 120, and a terminal device 130. The number of terminal devices and network devices included in the communication system 100 is not limited in the embodiments of the present application. It should be understood that fig. 1 is only exemplary and is not intended to limit the scope of protection claimed in this application. The terminal device 120 and the terminal device 130 may be any one of the terminal devices listed above, and the network device 110 may be any one of the network devices listed above.

In the communication system shown in fig. 1, communication between the terminal device 120 and the terminal device 130 may be performed through a PC5 interface, that is: SL communication is enabled between terminal device 120 and terminal device 130. Communication between terminal device 120 or terminal device 130 and network device 110 may also be via an air interface (Uu).

Optionally, the network device 110 may also connect with the LMF through a mobility management function (access and mobility management function, AMF).

In the communication system shown in fig. 1, in a Downlink (DL) scenario, the terminal device 120 measures PRS transmitted by the network device 110 and reports the measured value of PRS-RSRP to the LMF. The LMF determines the location of the terminal device 120 based on the measurement.

Specifically, by measuring two PRSs transmitted by network device 110 and network device 140 (not shown in fig. 1) respectively, terminal device 120 measures two measurements: a first measurement and a second measurement. Wherein the first measurement corresponds to a first PRS (transmitted by network device 110) and the second measurement corresponds to a second PRS (transmitted by network device 140). After the terminal device 120 reports the first measurement value and the second measurement value to the LMF, in combination with the respective transmit beam patterns of the network device 110 and the network device 140, can calculate a respective departure angle (angle of departure, AOD) of each network device.

It is understood that the transmit beam pattern of the network device may be transmitted to the LMF by the network device, or may be pre-stored in the LMF, which is not limited in this application.

In one example, the LMF may send the first measurement value and the second measurement value to corresponding network devices, respectively, and the network devices may calculate the AOD by themselves and report the first measurement value and the second measurement value to the LMF. For example, the LMF sends the first measurement to network device 110 and the second measurement to network device 140. The network device 110 calculates a first AOD from the first measurement value and reports the first AOD to the LMF. The network device 140 calculates a second AOD based on the second measurement and reports the second AOD to the LMF.

On the premise that the positions of all network devices are known, the LMF forms a ray which takes the position of the network device as a starting point and deflects the angle of the ray as the AOD based on the AOD of the network device. Further, the intersection point of the two rays determined by the LMF is the location of the terminal device.

Although the above description is an introduction to the existing DL-PRS based positioning principle, the basic principle of the SL based positioning technique is similar to the existing DL-PRS based positioning principle. The difference between the two is that: in the SL-based positioning technique, the terminal device 120 needs to report the measurement value of SL-PRS-RSRP to the LMF, namely: the terminal device 120 needs to measure the AOD of other terminal devices.

In the positioning technology based on SL, the resource allocation mode of SL-PRS is similar to the resource allocation mode of the existing DL-PRS, namely: the protocol may define the following information:

1. A start symbol (resource symbol offset) within the slot;

2. number of occupied symbols (number of symbols).

For DL-PRS, the DL-PRS does not need to configure automatic gain control (automatic gain control, AGC) symbols and GAP (GAP) symbols, and the transmit power is determined by the network device. Wherein each DL-PRS can only be transmitted using one antenna port.

For SL-PRS, each SL-PRS resource needs to be associated with one beam and transmitted using one antenna port. SL-PRS also requires configuration of AGC symbols and GAP symbols.

Specifically, an orthogonal frequency division multiplexing (orthogonal frequency division multiplexing, OFDM) symbol immediately following the last symbol of a physical side-downlink shared channel (PSSCH), a physical side-downlink feedback channel (PSFCH), or a secondary-synchronization signal and a PBCH block (S-SSB), or a side-downlink positioning reference signal (side-link positioning reference signal, SL-PRS) may be used as the GAP symbol (the OFDM symbol immediately following the last symbol used for PSSCH, PSFCH or S-SSB serve as a guard symbol).

Wherein, as described in paragraphs 8.3.1.5and8.3.2.3, the first OFDM symbol repetition (the first OFDM symbol of a PSSCH and its associated PSCCH is duplicated as descripted in clauses 8.3.1.5and 8.3.2.3) of the PSSCH and its associated physical side uplink control channel (PSCCH). In addition, the first OFDM symbol of the PSFCH and its associated PSCCH is replicated as described in clause 8.3.4.2.2 (the first OFDM symbol of a PSFCH and its associated PSCCH is duplicated as descripted in clauses 8.3.4.2.2). It should be appreciated that the first OFMD symbol described above may be understood as an AGC symbol.

The resource elements for PSCCH in the first OFDM symbol of the mapping operation described above, including any demodulation reference signals (demodulation reference signal, DMRS), phase-tracking reference signals (PT-RS) or channel state information (channel state information, CSI) -Reference Signals (RS), or side-uplink positioning reference signals (side-link positioning reference signal, SL-PRS) that occur in the first OFDM symbol should be replicated (the resource elements used for the PSCCH in the first OFDM symbol in the mapping operation above including any DM-RS, PT-RS or CSI-RS occurring in the first OFDM symbol shall be duplicated in the immediately preceding OFDM symbol) in the immediately preceding OFDM symbol.

In the SL-based positioning technique, the terminal device 120 needs to measure SL-PRS transmitted by a plurality of terminal devices. If multiple SL-PRSs are transmitted using multiple transmit beams, additional configuration of AGC symbols and GAP symbols is required. The AGC symbol is used for adjusting an operating point by the receiving end, so that the gain of the amplifying circuit is automatically adjusted according to the signal strength, and the GAP symbol is used for receiving and transmitting the conversion by the receiving end, as can be seen in fig. 2.

Fig. 2 is a schematic diagram of a time domain resource configuration of SL-PRS. As shown in fig. 2, the time domain resources of the first SL-PRS and the time domain resources of the second SL-PRS each include one AGC symbol and one GAP symbol. The AGC symbol may be a first symbol of a time domain resource of the SL-PRS and the GAP symbol may be a last symbol of the time domain resource of the SL-PRS. The time domain resources of the first SL-PRS are separated from the time domain resources of the second SL-PRS by GAP symbols. The symbols between the AGC symbols and the GAP symbols are used to actually transmit SL-PRS.

As can be seen from fig. 2, if multiple SL-PRSs are transmitted through multiple transmit beams, one AGC symbol needs to be configured for each of the time domain resources of the SL-PRSs, which results in a large overhead for allocation and scheduling of the time domain resources of the SL-PRSs.

In view of the above technical problems, the present application provides a method for configuring resources and a communication device, which can complete transmission of a side uplink positioning reference signal with low overhead of an automatic gain control symbol.

The resource configuration method of the embodiment of the present application will be described below with reference to the accompanying drawings.

Fig. 3 is an interactive flow diagram of a method 300 for configuring resources according to an embodiment of the present application. The method flow in fig. 3 may be performed by the first communication device, or performed by a module and/or a device (e.g., a chip or an integrated circuit, etc.) installed in the first communication device and having a corresponding function, which embodiments of the present application are not limited to. The first communication means may be a network device or a terminal device. The first communication device will be described below as an example. As shown in fig. 3, the method 300 includes:

s310, the first communication device determines M symbols of a first time unit, the first X symbols in the M symbols are used for transmitting AGC symbols, the M symbols are also used for transmitting N SL-PRSs, the N SL-PRSs at least comprise a first SL-PRS and a second SL-PRS, the first SL-PRS occupies a first symbol set, the second SL-PRS occupies a second symbol set, M is more than or equal to 2, X is more than or equal to 1, and N is more than or equal to 2.

In particular, M symbols determined by the first communication device may be used to transmit the AGC symbols with N SL-PRSs. Wherein each of the N SL-PRSs may each occupy a different set of symbols, e.g., a first SL-PRS occupies a first set of symbols and a second SL-PRS occupies a second set of symbols. The number of symbols in each symbol set may be the same or different, which is not limited in this application. The number of symbols in each symbol set may be one or a plurality of symbols, and the present application is not limited thereto. For convenience of description, the embodiments of the present application will be described by taking m=5, x=1, and n=2 as examples, but are not limited to other values.

It should be appreciated that the OFDM symbols used to transmit the AGC symbols may also be used to transmit the first SL-PRS, i.e., the AGC symbols may be multiplexed with the first SL-PRS by the same OFDM symbol. Therefore, the above relationship of M.gtoreq.2, X.gtoreq.1, N.gtoreq.2 holds true.

In one example, one of the 5 symbols within the first time unit determined by the first communication device may be used to transmit an AGC symbol and the remaining four symbols may be used to transmit the first SL-PRS and the second SL-PRS.

In one possible implementation, the first SL-PRS occupies a first set of symbols, the first set of symbols including at least one symbol, and the second SL-PRS occupies a second set of symbols, the second set of symbols including at least one symbol. The following continues with the description of the arrangement relationship between the first symbol set and the second symbol set.

In this embodiment, the number of AGC symbols used for transmitting may be one or more, that is: AGC symbols may be transmitted by occupying one or more OFDM symbols. In this way, the SL-PRS transmission can be completed with lower AGC symbol overhead.

In one possible implementation, the present application also supports side-uplink positioning between other signal-participating devices. For example, sounding reference signals (sounding reference signal, SRS), or side-uplink control information (SCI), etc.

For ease of description, the embodiments of the present application will be described with respect to SL-PRS, but are not limited to other types of signals. Therefore, some or all descriptions of the SL-PRS in the present application may be equally applicable to other types of signals, and are not described in detail herein.

It will be appreciated that the AGC symbols may be replaced by other signals having the same function and different names, and the present application is not limited to the expression AGC symbols.

As can be seen from fig. 2, the time domain resources of the first SL-PRS include one AGC symbol and one GAP symbol, and the time domain resources of the second SL-PRS also include one AGC symbol and one GAP symbol, which makes the overhead of the AGC symbols in the time domain resources of the SL-PRS larger. By combining the technical scheme disclosed by the embodiment of the application, the time domain resource of the second SL-PRS does not comprise the AGC symbol, so that the cost of the AGC symbol can be saved. Specific details will be described below.

S320, the first communication device transmits the AGC symbol and N SL-PRSs on M symbols.

The first communication device may complete the transmission of AGC symbols and N SL-PRSs on M symbols, which in turn may enable inter-device side-uplink positioning.

In summary, through the above technical scheme, the present application can achieve the completion of the transmission of the SL-PRS with lower overhead of the AGC symbol.

In addition, the cost of AGC symbols in the time domain resource of SL-PRS is reduced, and the receiving complexity of a receiving end can be reduced.

In one possible implementation, the M symbols may be consecutive M symbols. In this way, the transmission of AGC symbols and multiple SL-PRSs on consecutive symbols may be achieved.

In one possible implementation, S320 may further include:

the first communication device transmits N SL-PRSs through K transmitting antennas, wherein K is more than or equal to 2.

Specifically, the first mapping rule is satisfied between K transmit antennas and N side-uplink positioning reference signals. The first communication device selects a corresponding transmit antenna from the K transmit antennas to transmit a corresponding SL-PRS via a first mapping rule. For example, if k=2 and n=2, the first mapping rule may be: the first transmit antenna (which may also be an antenna port) corresponds to a first SL-PRS and the second transmit antenna corresponds to a second SL-PRS.

When there is more SL-PRS than transmit antennas, one transmit antenna may correspond to one or more SL-PRS, which may be set according to a specific case, which is not limited in the present application.

Illustratively, when there are multiple transmit antennas, the first mapping rule may be: the first transmit antennas correspond to SL-PRS#1 and SL-PRS#2, and the second transmit antennas correspond to SL-PRS#3 and SL-PRS#4. The first mapping rule may also be: the first transmit antenna corresponds to SL-PRS#1, the second transmit antenna corresponds to SL-PRS#2, SL-PRS#3, SL-PRS#4, and so on.

Alternatively, the above description can also be understood as: the first communication device transmits the SL-PRS using an antenna or maps different antenna ports onto resources of different SL-PRS. The description is unified herein, and will not be repeated.

The present application supports transmitting multiple SL-PRSs over multiple transmit antennas. Meanwhile, when the plurality of SL-PRSs are transmitted through the plurality of transmit antennas, a first mapping rule between the plurality of transmit antennas and the plurality of SL-PRSs may be established. Therefore, the measuring capability of the side-link positioning angle of the communication device can be improved, and the cost and complexity in measuring the SL-PRS can be reduced.

Specifically, when the first communication apparatus transmits multiple SL-PRSs to the second communication apparatus according to the first mapping rule described above, different SL-PRSs may correspond to different transmit antennas, which may enable the second communication apparatus to receive the multiple SL-PRSs on the multiple transmit antennas, and may determine an angle between the multiple SL-PRSs, thereby completing inter-device side uplink positioning.

In one possible implementation, S320 may include:

the first communication device transmits N SL-PRSs through L transmission beams, wherein L is more than or equal to 2.

In particular, the second mapping rule is satisfied between the L transmit beams and the N sidelink positioning reference signals. Through the second mapping rule, the first communication device selects a corresponding transmit beam from the L transmit beams to transmit a corresponding SL-PRS. For example, if l=2 and n=2, the second mapping rule may be: the first transmit beam corresponds to a first SL-PRS and the second transmit beam corresponds to a second SL-PRS.

When there is more SL-PRS than transmit beams, one transmit beam may correspond to one or more SL-PRS, which may be set according to a specific case, which is not limited in this application.

Illustratively, when there are multiple transmit beams, the second mapping rule may be: the first transmit beam corresponds to SL-PRS#1 and SL-PRS#2 (or the first communication device transmits different SL-PRS using different transmit beams), and the second transmit beam corresponds to SL-PRS#3 and SL-PRS#4. The second mapping rule may also be: the first transmit beam corresponds to SL-PRS#1, the second transmit beam corresponds to SL-PRS#3, SL-PRS#2, SL-PRS#4, and so on.

The present application supports transmitting multiple SL-PRSs over multiple transmit beams. When transmitting the plurality of SL-PRSs over the plurality of transmit beams, a second mapping rule between the plurality of transmit beams and the plurality of SL-PRSs may be established. Therefore, the measuring capability of the side-link positioning angle of the communication device can be improved, and the cost and complexity in measuring the SL-PRS can be reduced.

Specifically, when the first communication apparatus transmits multiple SL-PRSs to the second communication apparatus according to the second mapping rule described above, different SL-PRSs correspond to different transmission beams, which may enable the second communication apparatus to receive the multiple SL-PRSs on the multiple transmission beams, and may determine an angle between the multiple SL-PRSs, and finally complete inter-device side uplink positioning.

Optionally, the first mapping rule and/or the second mapping rule may be predefined by a protocol (e.g. a 3GPP protocol), or may be indicated by the second communication device to the first communication device.

In one possible implementation, the first communication device determines that the M symbols are implemented by receiving configuration information # 1. That is, the first communication apparatus receives the configuration information #1, and the configuration information #1 is used to configure the M symbols described above. For example, the configuration information #1 may include time domain configuration information of AGC and time domain configuration information of N SL-PRSs in the first time unit. In this way, the first communication apparatus completes transmission of the side uplink positioning reference signal according to the time domain configuration information of the M symbols included in the configuration information # 1.

In one possible implementation, the configuration information #1 may be further used to configure the first mapping rule and/or the second mapping rule.

In one possible implementation, the first time unit includes any one of the following: time slots, subframes, or system frames.

In one possible implementation manner, when k=2 and n=2, the first mapping rule may include:

the first SL-PRS is mapped to a first transmit antenna and the second SL-PRS is mapped to a second transmit antenna.

In one possible implementation, when l=2 and n=2, the second mapping rule may include:

the first SL-PRS is mapped to a first transmit beam and the second SL-PRS is mapped to a second transmit beam.

Alternatively, the first transmit beam may be the strongest transmit beam. The first communication device determines the strongest transmit beam (i.e., the first transmit beam) by a previous SL data transmission or beam sweep. The first communication device determines a symbol for transmitting AGC from the above 5 symbols according to the first transmission beam.

Alternatively, the second transmit beam may be an adjacent transmit beam differing from the power of the first transmit beam by a fixed value, which may be 10-15dBm, for example, or other values. The time domain resource of the second SL-PRS corresponding to the second transmit beam may not require an AGC symbol. Therefore, the cost of AGC symbols can be reduced, time domain resources of SL-PRS can be reasonably configured, and the cost of allocation and scheduling when the time domain resources of SL-PRS are configured can be reduced.

Through the technical scheme, the transmission of the SL-PRS can be completed with lower cost of the AGC symbol.

In addition, the present application can also achieve reduced reception complexity at the receiving end by reducing the overhead of AGC symbols in the time domain resources used to transmit SL-PRS.

In one possible implementation, the first set of symbols may include two symbols (hereinafter referred to as symbol a), and the second set of symbols may include two symbols (hereinafter referred to as symbol B).

Specifically, symbol a corresponds to a symbol between an AGC symbol and a GAP symbol of a time domain resource of a first SL-PRS shown in fig. 2, and symbol B corresponds to a symbol between an AGC symbol and a GAP symbol of a time domain resource of a second SL-PRS shown in fig. 2.

In one possible implementation manner, any one of the following is satisfied between the first symbol set and the second symbol set:

1) The symbol B is not included between any two symbols A; (mapping rule # 1)

2) At least two symbols A include at least one symbol B therebetween; (mapping rule # 2)

3) The symbol A is not included between any two symbols B; (mapping rule # 3)

4) At least two symbols B include at least one symbol a therebetween. (mapping rule # 4)

In brief, one or more symbols of the second set of symbols are not included between any two symbols of the first set of symbols; alternatively, at least two symbols in the first set of symbols include one or more symbols of the second set of symbols therebetween.

Illustratively, any two symbols a do not include symbol B therebetween, and may be: AABB. In brief, a plurality of symbols a in the first symbol set are centrally distributed, and a plurality of symbols B in the second symbol set are centrally distributed. At least a second symbol B is included between at least a pair of symbols a, which may be: AABBAABB or abaabbbbaaaabbbb, etc. Briefly, a sparse distribution is satisfied between the first set of symbols and the second set of symbols. The symbol A is not included between any two symbols B, and can be: AABBBBBB. In brief, the plurality of symbols of the first set of symbols are distributed in a set of symbols and the plurality of symbols of the second set of symbols are distributed in a set of symbols. At least one symbol a is included between at least one pair of symbols B, which may be: AABBAABB or abbabbbaaaabbbb, etc. Briefly, a sparse distribution is satisfied between the first set of symbols and the second set of symbols. See fig. 4 and 5 for details.

Fig. 4 is a schematic diagram of a first mapping rule according to an embodiment of the present application. As shown in fig. 4 (a), m=6, the number of agc symbols is 1, the number of gap symbols is 1, the first SL-PRS occupies 2 symbols, and the second SL-PRS occupies 2 symbols. Two symbols occupied by the first SL-PRS (centrally arranged) are mapped to the first transmit antenna and two symbols occupied by the second SL-PRS (centrally arranged) are mapped to the second transmit antenna (see mapping rule # 1). As shown in fig. 4 (b), m=6, the number of agc symbols is 1, the number of symbols of gap is 1, the first SL-PRS occupies 2 symbols, and the second SL-PRS occupies 2 symbols. Two symbols occupied by the first SL-PRS (separately arranged) are mapped to the first transmit antenna and two symbols occupied by the second SL-PRS (separately arranged) are mapped to the second transmit antenna (see mapping rule # 2). Fig. 5 is a schematic diagram of a second mapping rule according to an embodiment of the present application. As shown in fig. 5 (a), m=6, the number of agc symbols is 1, the number of gap symbols is 1, the first SL-PRS occupies 2 symbols, and the second SL-PRS occupies 2 symbols. Two symbols occupied by the first SL-PRS (centrally arranged) are mapped to the first transmit beam and two symbols occupied by the second SL-PRS (centrally arranged) are mapped to the second transmit beam (see mapping rule # 1). As shown in fig. 5 (b), m=6, the number of agc symbols is 1, the number of symbols of gap is 1, the first SL-PRS occupies 2 symbols, and the second SL-PRS occupies 2 symbols. Two symbols occupied by the first SL-PRS (separately arranged) are mapped to the first transmit beam and two symbols occupied by the second SL-PRS (separately arranged) are mapped to the second transmit beam (see mapping rule # 2).

The foregoing is to be understood as being merely illustrative, and the embodiments of the present application are not limited to specific arrangements.

Alternatively, the first symbol set and the second symbol set may be scheduled across a timeslot/subframe/system frame, or may be scheduled in the same timeslot/subframe/system frame, which is not limited in this application.

In one possible implementation, the second communication device may indicate the first mapping rule and/or the second mapping rule to the first communication device by using indication information.

Optionally, the indication information includes any one of the following: semi-static signaling such as radio resource control (radio resource control, RRC) signaling, medium access control-element (MAC-CE), and PC 5-RRC.

Optionally, the indication information further includes any one of the following: dynamic signaling of downlink control information (downlink control information, DCI), SCI and PSSCH.

Alternatively, the second communication device may indicate by a part of bits when indicating by a dynamic or semi-static manner. For example, 2 is represented by G bits ^G Each bit combination, different bit combinations representing different mapping rules, respectively. Wherein the G bits may be reserved bits on DCI, SCI and PSSCH or new field/bits of dynamic signaling.

Illustratively, when g=1, "0" represents a mapping rule #1, and "1" represents a second mapping rule #2.

Illustratively, when g=2, "00" represents a mapping rule #1, "10" represents a mapping rule #2, "01" represents a mapping rule #3, "11" represents a mapping rule #4, and the like, which is not limited in this application.

In one possible implementation, the second communication device may indicate, via one or more bits, whether to employ the aforementioned disclosed low ACG symbol mode.

Illustratively, the second communication device indicates a multiple AGC symbol mode by bit 1, a fewer AGC symbol mode by bit 0, and so on, or vice versa, without limitation of the present application.

Alternatively, the first mapping rule and the second mapping rule may be predefined.

Specifically, the multi-AGC symbol mode means that the number of AGC symbols is consistent with the number of SL-PRSs. The small AGC symbol mode means that the number of AGC symbols is less than the number of SL-PRSs. The description is unified herein, and will not be repeated.

In one possible implementation, the first communication device may also receive the indication information before transmitting the SL-PRS. Wherein the indication information can be used to indicate the first mapping rule or the second mapping rule.

Through the technical scheme, the first communication device acquires the mapping rule between the transmitting antenna or the transmitting beam and the SL-PRS, and determines the proper transmitting antenna or the transmitting beam to transmit the SL-PRS based on the acquired mapping rule, so that the side uplink positioning process between the devices is completed.

Alternatively, the source from which the first communication device receives the indication information may be plural. For example, the indication information may be part of the pre-configuration information (e.g., factory configuration), part of the SCL information, or part of the PC5 RRC information. Specific details are described further below.

In addition, this may increase the flexibility of the indication.

The method of configuring the resources shown in fig. 3 will be further described below in conjunction with fig. 6.

Fig. 6 is an interactive flow diagram of a method 600 for configuring resources according to an embodiment of the present application. The method flow in fig. 6 may be performed by the terminal device 120 or by a module and/or a device (e.g., a chip or an integrated circuit, etc.) installed in the terminal device 120 with corresponding functions. The following description will take the terminal device 120 as an example. As shown in fig. 6, the method 600 includes:

optionally, S601, the terminal device 120 receives configuration information #1, which is used to configure the M symbols described above.

Specifically, configuration information #1 includes time domain configuration information of an AGC symbol in a first time unit and time domain configuration information of N SL-PRSs. Through the configuration information #1, the terminal device 120 determines time domain configuration information of each symbol of the M symbols, thereby completing transmission of SL-PRS.

Alternatively, the terminal device 120 may receive the configuration information #1 from the network device 110, or the terminal device 120 may receive the configuration information #1 from the terminal device 130, or the configuration information #1 may be preconfigured, which is not limited to a specific implementation.

In one possible implementation, when the terminal device 120 obtains the configuration information #1 through a pre-configuration or a manner instructed by the network device 110, the terminal device 120 may also send the configuration information #1 to the terminal device 130. The terminal device 130 determines the above-described M symbols based on the configuration information #1 transmitted by the terminal device 120.

Optionally, S610, the terminal device 120 receives the first information, which is used to configure the SL positioning parameter.

The first information received by the terminal device 120 may be from the network device 110, or from the preconfigured information, or from the terminal device 130. For example, the network device 110 may send RRC signaling to the terminal device 120, the RRC signaling including the first information. For example, the first information is stored in the terminal device 120 by a preconfigured technical means, such as factory settings.

In one possible implementation, the first information may further include configuration information #1.

Alternatively, the first information may be preconfigured information, which may also be used to configure information required for the underlying communication/positioning procedure, such as SL positioning parameters.

Alternatively, the first information may also be statically configured, without requiring a fast update, so that signaling overhead may be saved.

In one possible implementation, the SL positioning parameters include at least one of:

a first mapping rule, opening antenna port switching capability, or a second mapping rule.

Illustratively, the terminal device 120 is capable of obtaining a first mapping rule, namely: the terminal equipment 120 may transmit the corresponding SL-PRS over different transmit beams (alternatively, the terminal equipment 120 may transmit the corresponding SL-PRS using different power). The terminal device 120 can switch different antenna ports according to the open antenna port switching capability parameter. The terminal device 120 can obtain a second mapping rule, namely: the terminal device 120 may transmit the corresponding SL-PRS through different transmit antennas.

Optionally, the SL positioning parameters may further include: either a multiple AGC symbol mode or a fewer AGC symbol mode is used.

In one possible implementation, the first information includes indication information. Wherein, the term "comprising" is understood as: the indication information is part of the first information, or the first information is the indication information, which is not limited in this application.

S620, the terminal device 120 sends SL location request information to the terminal device 130 for requesting the SL location service between the terminal device 120 and the terminal device 130.

Accordingly, the terminal device 130 receives the SL location request information transmitted from the terminal device 120, and initiates the SL location service based on the SL location request information.

Optionally, the SL positioning request information may also carry quality of service (quality of service, qoS) indicators, such as delay, accuracy, etc.

Alternatively, the SL positioning request information transmitted from the terminal device 120 to the terminal device 130 may also include configuration information #1.

S630, the terminal device 130 sends second information to the terminal device 120, for configuring SL positioning report information.

Accordingly, the terminal device 120 receives the second information transmitted from the terminal device 130.

Specifically, the second information may be configured between the terminal device 120 and the terminal device 130 through PC5-RRC signaling.

In one possible implementation, the SL location reporting information includes at least one of:

1) Locating the reporting type of measurement. Such as: SL-AOD, SL-arrival Time (TOA), SL-relative arrival time (relative time of arrival, RTOA), etc.;

2) Non-positioning measurement reporting type. Such as: one or more of serving base station information of the terminal device, absolute position information of the terminal device, and orientation information;

3) Whether the reverse transmission of the SL-PRS is needed or not, and the triggering state of the SL-PRS of the reverse transmission;

4) Whether a different transmit beam or transmit antenna is required to transmit the SL-PRS;

5) A first mapping rule and/or a second mapping rule;

6) An available transmit panel (Tx panel) and transmit antenna (Tx port) (i.e., an available transmit beam or transmit antenna);

7) Multiple AGC symbol patterns and/or fewer AGC symbol patterns are used.

With the above information, the terminal device 120 can clearly use what way to perform SL positioning measurement, and then, SL positioning can be performed better between the terminal device 120 and the terminal device 130.

S640, the terminal device 120 transmits sci#a to the terminal device 130.

Accordingly, the terminal device 130 receives sci#a transmitted from the terminal device 120, the sci#a being used for scheduling pssch#a. The pssch#a may include request information for requesting the terminal device 130 to transmit SL location report information, or may include SL location report information transmitted from the terminal device 120 to the terminal device 130.

In one possible implementation, the second information includes indication information. Wherein, the term "comprising" is understood as: the indication information is part of the second information, or the second information is the indication information, which is not limited in this application.

In one possible implementation, before sending sci#a to terminal device 130, terminal device 120 receives dci#a sent by network device 110, which is used to schedule SL-PRS for sending SL-prs#a.

In one possible implementation, dci#a may indicate a transmission mode of SL-PRS through reserved bits (e.g., 2 bits) or a new SCI field, for example, a single-beam transmission mode, a single-antenna port transmission mode, a multi-beam transmission mode, a multi-antenna port transmission mode; alternatively, the mapping rule between the SL-PRS and the transmit beam or transmit antenna.

Alternatively, dci#a may also indicate a multiple AGC symbol mode or a fewer AGC symbol mode through reserved bits or a new SCI field.

In one possible implementation, sci#a may also indicate the transmission mode of SL-PRS by a reserved bit (e.g., 2 bits) or a new SCI field, e.g., single beam transmission mode, single antenna port transmission mode, multi-beam transmission mode, multi-antenna port transmission mode; alternatively, the mapping rule between the SL-PRS and the transmit beam or transmit antenna. In other words, SCI#A may also be used to indicate the transmission mode of SL-PRS. Dynamic indication can be realized through SCI, and the first communication device can dynamically adjust the transmission mode according to the channel condition, so as to improve the positioning measurement effect.

Alternatively, sci#a may also indicate a multiple AGC symbol pattern or a fewer AGC symbol pattern by a reserved bit or a new SCI field.

In addition, by reserving bits, the present application may not add additional dynamic signaling overhead.

In one possible implementation, sci#a may also be used to indicate the first mapping rule and/or the second mapping rule.

The SL-PRS transmission mode of terminal device 120 may be indicated by network device 110. In this manner, terminal device 120 is able to transmit SL-PRS according to the direction of network device 110.

The terminal device 130 determines a transmission mode in which the terminal device 120 is to transmit the SL-PRS according to the sci#a transmitted by the terminal device 120. For example, the terminal device 120 indicates that the transmission mode of the SL-PRS is a multi-beam transmission mode through the sci#a, and the terminal device 130 determines that the terminal device 120 transmits a plurality of SL-PRSs through the multi-beam according to the sci#a. Alternatively, the terminal device 120 indicates that the transmission mode of the SL-PRS is the transmission mode of the multi-antenna port through the sci#a, and the terminal device 130 determines that the terminal device 120 will transmit the multiple SL-PRSs through the multi-antenna port according to the sci#a.

Accordingly, the terminal device 130 may perform corresponding SL-PRS measurements according to SCI#A.

It should be appreciated that the number of trigger status bits in sci#a may be configured by the first information. The field value corresponding to the triggering state in SCI#A is used for searching the triggered SL-PRS and the requested SL positioning reporting information.

S650, the terminal device 120 transmits pssch#a to the terminal device 130.

The terminal device 120 determines the strongest transmit beam from the pssch#a transmission and thus determines the AGC symbol. In other words, PSSCH#A can be used by the terminal device 120 to determine the strongest transmit beam or AGC symbol.

S660, the terminal device 120 sends SL-PRS#A to the terminal device 130.

Specifically, SL-PRS#A corresponds to a trigger state in SCL#A.

Alternatively, the SL-prs#a transmitted by the terminal device 120 to the terminal device 130 is transmitted through a first transmit beam or a first transmit antenna.

In one possible implementation, SL-PRS#A sent by terminal device 120 to terminal device 130 may be used for AOD measurements.

By the technical scheme, the method and the device can support the implementation of the side uplink positioning between the devices with lower cost of AGC symbols.

In one possible implementation, the method 400 may further include:

s660, terminal device 130 transmits sci#b to terminal device 120.

Accordingly, terminal device 120 receives sci#b transmitted from terminal device 130. The description of sci#b may refer to the description of sci#a, and will not be described herein.

S670, the terminal device 130 transmits pssch#b to the terminal device 120.

Accordingly, the terminal device 120 receives the pssch#b transmitted from the terminal device 130. The description of pssch#b may refer to the description of pssch#a, and will not be described herein.

S680, the terminal device 130 sends SL-PRS#B to the terminal device 120.

Accordingly, the terminal device 120 receives the SL-PRS#B transmitted from the terminal device 130. The description of the SL-prs#b may refer to the description of the SL-prs#a, and will not be described herein.

In one possible implementation, terminal device 120 sends multiple SCIs to terminal device 130. When the terminal device 120 transmits a plurality of SCIs to the terminal device 130, the correspondence between the SL-PRS transmitted by the terminal device 120 to the terminal device 130 and the plurality of SCIs may be configured by the first information. For example, the terminal device 120 transmits the SL-PRS corresponding to the first SCI among the plurality of SCIs to the terminal device 130 according to the information configured by the first information.

In one possible implementation manner, the first information, the second information, the sci#a, and the like may include indication information, that is, information for configuring the first mapping rule and/or the second mapping rule may be carried in the first information, the second information, the sci#a, and the like.

It should be understood that although S610 to S680 are described as an example, the present application does not limit all steps in S610 to S680 to the essential steps, and some steps may be omitted or combined with each other.

In addition, the sequence of the adjacent steps in S610 to S680 is not limited in the present application.

It should be understood that the content shown in fig. 6 is only exemplary, and any flow or modification derived based on fig. 6 should be regarded as one of the technical solutions disclosed in the embodiments of the present application.

It should be appreciated that the network device 110 in the flow chart shown in fig. 6 may be communicatively coupled to the terminal device 120 as well as the terminal device 130. The network device 110 may perform the methods or steps related to the foregoing processes, and specific details may be found in the foregoing description, which is not repeated herein.
