[0034] The embodiments of the present disclosure provide a communication method and apparatus, a communication device, a communication system, and a storage medium.

[0035] In a first aspect, an embodiment of the present disclosure provides a communication method, the method comprising:

[0036] The first device determines N candidate positions of a positioning reference signal, where N is a positive integer greater than 1;

[0037] The first device sends the positioning reference signal at a first candidate position, wherein the first device detects that a channel is idle before the first candidate position, the N candidate positions include the first candidate position, and the channel is a channel where a shared spectrum is located.

[0038] In the above embodiment, the first device determines N candidate positions for a positioning reference signal, where N is a positive integer greater than 1. When the first device detects that the channel is idle before a candidate position, it determines the candidate position as the first candidate position and sends a positioning reference signal at the first candidate position. It can be seen that in the embodiment of the present disclosure, there are N candidate positions corresponding to the positioning reference signal. The first device determines whether the channel is idle before each candidate position to try to see whether the positioning reference signal can be sent at the candidate position. Since there are multiple candidate positions, the success rate of sending the positioning reference signal can be greatly improved, ensuring that the positioning measurement can be performed stably and accurately.

[0039] In combination with some embodiments of the first aspect, in some embodiments, the number of the first candidate positions is no greater than 1.

[0040] In the above embodiment, by ensuring that the number of first candidate positions used by the first device to send a positioning reference signal is no more than 1, so as to ensure that the first device successfully sends a positioning reference signal, the situation of "the first device causing channel busyness due to frequent or multiple transmissions of positioning reference signals, thereby affecting other devices' transmission of positioning reference signals" is further avoided. This ensures that other devices can send positioning reference signals in a timely manner, guarantees the accuracy of positioning measurements, and reduces positioning delays.

[0041] In combination with some embodiments of the first aspect, in some embodiments, the interval value between adjacent candidate positions is less than a first threshold.

[0042] In the above embodiment, the interval value between adjacent candidate positions is small. Therefore, when multiple first devices are required to send positioning reference signals to the second device for the second device to perform positioning measurement, even if different first devices send positioning reference signals at different first candidate positions due to different determined first candidate positions, since the interval between different candidate positions is small, even if different first devices send positioning reference signals at different first candidate positions, the time intervals between different first devices sending positioning reference signals will be small, thus avoiding the situation of "due to the large interval between the received positioning reference signals, the positioning result is determined by using the positioning reference signals sent by the transmitter at multiple times with a large time interval", thereby reducing the positioning delay and further ensuring the positioning accuracy.

[0043] In conjunction with some embodiments of the first aspect, in some embodiments, determining N candidate positions of the positioning reference signal includes at least one of the following:

[0044] receiving first information for configuring N candidate positions of a positioning reference signal;

In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0238] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0239] The following embodiments of the present disclosure may be applied to the communication system 100 shown in Figure 1, or a portion thereof, but are not limited thereto. The entities shown in Figure 1 are illustrative only. The communication system may include all or part of the entities shown in Figure 1, or may include other entities outside of Figure 1. The number and form of the entities may be arbitrary. The connection relationship between the entities is illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0240] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0241] Optionally, in a communication system, for downlink positioning measurements, the introduced positioning reference signal is: downlink positioning reference signal (PRS); for uplink positioning measurements, the introduced positioning reference signal is: sounding reference signal (SRS); for sidelink (SL) measurements, the introduced positioning reference signal is: SL PRS and / or SL SRS; Optionally, in some embodiments, during positioning measurements, the above-mentioned positioning reference signal is usually sent on the authorized spectrum, that is, the transmission time of the positioning reference signal is configured, and if the transmission time does not conflict with the resources of other signals, the positioning reference signal is sent at the transmission time. The other signals here refer to other signals that need to be sent or received by the same sending point corresponding to the positioning reference signal.

[0242] In some embodiments, in order to improve positioning bandwidth and spectrum utilization, the transmission and reception of positioning reference signals based on unlicensed spectrum are introduced. Among them, unlicensed spectrum and shared spectrum can be replaced with each other. Optionally, at least one transmission time of positioning reference signals will also be configured on the unlicensed spectrum. Before each transmission time, the transmitter needs to perform a channel access procedure (channel access procedure), including but not limited to listen before talk (LBT) to monitor the channel status of the unlicensed spectrum. Optionally, the transmitter needs to first monitor the energy on the unlicensed spectrum. If the energy intensity is lower than the threshold, it means that the channel of the unlicensed spectrum is not occupied by other devices, that is, the channel of the unlicensed spectrum is in an idle state, and LBT is successful. At this time, the transmitter will send the positioning reference signal through the unlicensed spectrum at the next transmission time. If the energy intensity is higher than the threshold, it means that the channel of the unlicensed spectrum is occupied by other devices, that is, the channel of the unlicensed spectrum is busy and LBT fails. At this time, the transmitter cannot use the unlicensed spectrum to send the positioning reference signal in the next transmission time.

[0243] However, in some embodiments, positioning measurement generally requires multiple transmitters to send positioning reference signals. For example, a PRS-based positioning method requires multiple TRPs to send PRSs, and a SL-PRS-based positioning method requires multiple UEs or PRUs to send SL PRSs or SL SRSs. In this case, the receiving end measures the positioning reference signals of multiple transmitters at simultaneous or adjacent transmission times and obtains accurate positioning results based on the measurement results. However, due to the different surrounding environments of the multiple transmitters, the LBT results may also be different. For example, at the same or similar transmission time, some transmitters may succeed in LBT while some may fail in LBT. This may result in some transmitters being able to successfully send positioning reference signals while some may not be able to successfully send positioning reference signals. In this case, the receiving end may only be able to receive positioning reference signals sent by a smaller number of transmitters at the same or similar transmission time, which may affect the positioning accuracy. Moreover, if these transmitters are far away from the positioning target, the positioning accuracy may be further affected.

[0244] Alternatively, in other embodiments, the positioning reference signal may also be configured with a number of repeated transmissions, and the number of repeated transmissions is mainly used to avoid losing a certain transmission when it may conflict with other signals that the positioning reference signal transmission point needs to send or receive. The time interval between two adjacent repeated transmissions is at the slot level, and multiple repeated transmissions can all be sent if there is no conflict with other signals. In this case, the receiving end may use the positioning reference signal sent by the transmitting end at multiple transmission times with a large time interval to determine the positioning result. However, for a receiving end in a mobile state, this method may cause the receiving end to be in a different position when receiving the positioning reference signal sent by the transmitting end at multiple transmission times with a large time interval, which will also reduce the positioning accuracy and increase the positioning delay.

[0245] FIG2A is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2A , the embodiment of the present disclosure relates to a communication method for use in a communication system 100, the method comprising:

[0246] Step 2101: The first device determines N candidate positions of a positioning reference signal.

[0247] Optionally, N is a positive integer greater than 1.

[0248] Optionally, in some embodiments, the positioning reference signal may include at least one of the following: PRS; SRS; SL PRS; SL SRS.

[0249] Optionally, in some embodiments, the first device may be a transmitter of a positioning reference signal. Optionally, when the positioning reference signal is a PRS, the first device may be a TRP, a base station, or a PRU; when the positioning reference signal is an SRS, a SL PRS, or a SL SRS, the first device may be a UE or a PRU.

[0250] In some embodiments, the N candidate positions may indicate possible transmission positions of a positioning reference signal. In some embodiments, the N candidate positions may be used to: when a first device needs to transmit a positioning reference signal, the first device may determine, from the N candidate positions, a first candidate position for transmitting the positioning reference signal based on previous channel states of each candidate position.

[0251] Optionally, in some embodiments, the interval value between adjacent candidate positions is small, for example, it can be smaller than a first threshold value, such as X symbols or Y time slots, where X and Y are positive integers. By making the interval value between adjacent candidate positions small, when multiple first devices are required to send positioning reference signals to a second device for the second device to perform positioning measurements, even if different first devices send positioning reference signals at different first candidate positions due to different determined first candidate positions, since the interval between different candidate positions is small, even if different first devices send positioning reference signals at different first candidate positions, the time intervals between the different first devices sending positioning reference signals will be small, thus avoiding the situation of "using positioning reference signals sent by the transmitter at multiple times with a large time interval to determine the positioning result", thereby reducing positioning delay and further ensuring positioning accuracy.

[0252] Optionally, in some embodiments, the method for the first device to determine N candidate positions of the positioning reference signal may include at least one of the following:

[0253] receiving first information, where the first information is used to configure N candidate positions of a positioning reference signal;

[0254] N candidate positions of a positioning reference signal are determined based on a default rule.

[0255] Optionally, in some embodiments, the above-mentioned "receiving first information" may, for example, receive first information sent by at least one of a location management function (LMF), an access network device, and a UE. Optionally, when the first device is a TRP or a base station or a PRU, the first device may receive the first information sent by the LMF, for example, the first information sent by the LMF through an interface or protocol between the LMF and the base station, or the first device may autonomously determine the first information; when the first device is a UE or a PRU, the first device may receive the first information sent by at least one of the LMF, the access network device, and the UE. For example, the first information sent by the LMF through the Long Term Evolution Positioning Protocol (LPP) message can be received, or the first information sent by the access network device through at least one of the Radio Resource Control (RRC) signaling, the Media Access Control Control Element (MAC CE) signaling, and the Downlink Control Information (DCI) signaling can be received; or the first information sent by at least one of the RRC, MAC CE, sidelink control information (SCI), physical sidelink broadcast channel (PSBCH), physical sidelink shared channel (PSSCH), physical sidelink shared channel (PSCCH), and physical sidelink feedback channel (PSFCH) of the sidelink can be accessed.

[0256] Optionally, in some embodiments, the above-mentioned “determining N candidate positions of the positioning reference signal” may include at least one of the following methods:

[0257] Method 1: Determine a time window, where multiple positions in the time window are the starting positions of the candidate positions.

[0258] Optionally, in some embodiments, the multiple positions in the time window may be any time domain unit except the last M time domain units in the time window, where M is a positive integer and the M time domain units are the length of time occupied by the positioning reference signal. Optionally, the time domain unit may be, for example, at least one of a time slot and a symbol.

[0259] Optionally, in some embodiments, the aforementioned determined time window may be, for example, at least one of: a starting position of the time window, a window length, and an ending position. Optionally, in some embodiments, the starting position of the time window may include at least one of a starting time slot of the time window and a starting symbol of the time window; the window length may include at least one of a number of time slots and a number of symbols; and the ending position may include at least one of an ending time slot and an ending symbol.

[0260] Optionally, in some embodiments, when the starting position of the time window is the starting time slot, the window length is the number of time slots and the ending position is the ending time slot; when the starting position of the time window is the starting symbol, the window length is the number of symbols and the ending position is the ending symbol.

[0261] Method 2: Determine the starting position of each candidate position among N candidate positions.

[0262] Optionally, the starting position of the candidate position may include at least one of the following:

[0263] The starting time slot of the candidate position;

[0264] The starting symbol of the candidate position.

[0265] Method three: Determine the starting position of the first candidate position among N candidate positions and the interval value between adjacent candidate positions, and determine the starting positions of other candidate positions among the N candidate positions except the first candidate position based on the starting position of the first candidate position and the interval value between adjacent candidate positions.

[0266] Optionally, in some embodiments, the starting position of the first candidate position plus the interval value can be used to obtain the starting position of the second candidate position, and the starting position of the second candidate position plus the interval value can be used to obtain the starting position of the third candidate position, and so on, to obtain the starting position of each candidate position.

[0267] Optionally, in some embodiments, the end position of the first candidate position may be determined based on the start position of the first candidate position. For example, the end position of the first candidate position may be obtained by adding the start position of the first candidate position to the duration occupied by the positioning reference signal. Subsequently, the start position of the second candidate position may be obtained by adding the interval value to the end position of the first candidate position. The start position of the third candidate position may be obtained by adding the interval value to the end position of the second candidate position. The start position of each candidate position may be obtained by analogy. The end position of the same candidate position is the start position plus the duration occupied by the positioning reference signal.

[0268] Optionally, in some embodiments, the interval value may include at least one of the following:

[0269] Number of interval slots;

[0270] Number of interval symbols.

[0271] Optionally, in some embodiments, the interval value may be agreed upon by a protocol.

[0272] Optionally, in some embodiments, when the starting position of the first candidate position is the starting time slot, the interval value is the number of interval time slots; when the starting position of the first candidate position is the starting symbol, the interval value is the number of interval symbols.

[0273] Step 2102: The first device determines relevant information of a positioning reference signal.

[0274] Optionally, in some embodiments, the relevant information of the positioning reference signal may be used by the first device to determine how to send the positioning reference signal based on the relevant information.

[0275] Optionally, the relevant information of the positioning reference signal may include at least one of the following:

[0276] Time domain parameters of the reference signal for positioning purposes;

[0277] Frequency domain parameters of positioning reference signals;

[0278] Comb parameters of reference signals for positioning purposes;

[0280] Quasi Co-location (QCL) information of positioning reference signals;

[0281] Spatial relationship information of reference signals for positioning purposes;

[0282] Resource identification (Identity, ID) of the positioning reference signal;

[0283] Resource set ID of the reference signal for positioning purposes.

[0284] Optionally, in some embodiments, the time domain parameter may include at least one of the following:

[0285] cycle;

[0286] Start time slot;

[0287] Start symbol;

[0288] The number of occupied symbols;

[0289] Number of repeated transmissions;

[0290] The interval value between repeated transmissions.

[0291] Optionally, in some embodiments, the interval value between adjacent candidate positions is smaller than the interval value and the period between repeated transmissions.

[0292] Optionally, in some embodiments, the frequency domain parameter may include at least one of the following:

[0293] Frequency domain position;

[0294] Frequency domain offset;

[0295] Frequency hopping mode.

[0296] Optionally, in some embodiments, the comb parameter may include at least one of the following:

[0297] Comb value;

[0298] Circular shift.

[0299] Optionally, in some embodiments, the power control parameter may include at least one of the following:

[0300] P0 value;

[0301] alpha value;

[0302] Pathloss reference signal (pathloss RS).

[0303] Optionally, in some embodiments, the relevant information of the positioning reference signal may be sent to the first device by at least one of the LMF, the access network device, and the UE through the first information.

[0304] Step 2103: The first device sends a positioning reference signal at the first candidate location.

[0305] Optionally, in some embodiments, the first candidate location may be one of N candidate locations. Specifically, the first candidate location may be a candidate location immediately after the time point at which the first device detects that the channel is idle. In other words, in some embodiments, the first device may transmit the positioning reference signal at the first candidate location on the premise that the first device detects that the channel is idle before the first candidate location.

[0306] Optionally, the aforementioned channel may be a channel where a shared spectrum is located. Optionally, the shared spectrum may be understood as, for example, an unlicensed spectrum.

[0307] Optionally, the above “channel idleness detected” may be understood as detection of LBT success, for example.

[0308] Optionally, the above “detecting that the channel is idle” may be understood as detecting that the energy value on the channel where the shared spectrum is located is lower than a threshold.

[0309] Optionally, in some embodiments, the above-mentioned “sending a positioning reference signal at the first candidate position” may include:

[0310] The positioning reference signal is sent starting from the starting position of the first candidate position.

[0311] Optionally, in some embodiments, the number of the above-mentioned first candidate positions is not greater than 1. That is, in some embodiments, after the first device sends a positioning reference signal at the first candidate position, the positioning reference signal is no longer sent at other candidate positions after the first candidate position. By setting the number of first candidate positions for the first device to send positioning reference signals to be no greater than 1, on the premise of ensuring that the first device successfully sends the positioning reference signal, the situation of "the first device causing channel busy due to frequent or multiple transmissions of positioning reference signals, thereby affecting the transmission of positioning reference signals by other devices" is further avoided, thereby ensuring that other devices can send positioning reference signals in a timely manner, ensuring the accuracy of positioning measurement, and reducing positioning delay.
