Technical features in different embodiments can be combined to form new embodiments based on their inherent logical relationships.
[0167] The terminology used in the embodiments of this disclosure is for the purpose of describing particular embodiments only and is not intended to limit the scope of this disclosure.
[0168] In this embodiment of the disclosure, unless otherwise stated, elements expressed in the singular form, such as "a," "an," "the," "the," "the," "the," "the," "the," "this," etc., can mean "one and only one," or "one or more," "at least one," etc. For example, when using articles such as "a," "an," "the," etc. in translation, the noun following the article can be understood as either a singular expression or a plural expression.

The description of the descriptive objects is found in the claims or the context of the embodiments, and the use of prefixes should not constitute unnecessary restrictions. For example, if the descriptive object is a "field," the ordinal numbers preceding "field" in "first field" and "second field" do not restrict the position or order of the "fields." "First" and "second" do not restrict whether the "fields" they modify are in the same message, nor do they restrict the order of "first field" and "second field." Similarly, if the descriptive object is a "level," the ordinal numbers preceding "level" in "first level" and "second level" do not restrict the priority between "levels." Furthermore, the number of descriptive objects is not limited by ordinal numbers and can be one or more. For example, in "first device," the number of "devices" can be one or more.

[0204] [Corrected according to Rule 91, 07.03.2025] In some embodiments, research on ISAC technology mainly focuses on scenarios such as Transmit-Receive Point (TRP, such as base station)-TRP bistatic, TRP monostatic, TRP-UE bistatic, UE-TRP bistatic, UE-UE bistatic, and UE monostatic. During the design process of an ISAC system, the service requirements for both communication and sensing need to be considered simultaneously. These six scenarios can be explained as follows (as shown in Figure 1C):
[0205] The base station transmits and receives signals (or gNB transmits and receives signals, i.e., TRP monostatic). The base station sends sensing signals, which, after passing through the environment or objects in the environment, are received and measured by the same base station as reflected / scattered waves.
[0206] Base station A transmits and base station B receives (or gNB A transmits and base station B receives, i.e., TRP-TRP bistatic). Base station A transmits a sensing signal, which passes through the environment or objects in the environment, and base station B receives and measures the reflected / scattered waves.
[0207] The terminal transmits and the base station receives (or the UE transmits and the gNB receives, i.e., UE-TRP bistatic). The terminal sends a sensing signal, which passes through the environment or objects in the environment, and the base station receives and measures the reflected / scattered waves.
[0208] The base station transmits and the terminal receives (or the gNB transmits and the UE receives, i.e., TRP-UE bistatic). The base station sends a sensing signal, which is reflected by the object being measured, and the terminal receives and measures the reflected / scattered wave.
[0209] Terminal-based self-transmission and self-reception (or UE-based self-transmission and self-reception, i.e., UE monostatic). The terminal sends a sensing signal, which passes through the environment or objects in the environment, and the same terminal receives and measures the reflected / scattered waves.
[0210] Terminal A transmits and B receives (or UE A transmits and B receives, i.e., UE-UE bistatic). Terminal A sends a sensing signal, which passes through the environment or objects in the environment, and Terminal B receives and measures the reflected / scattered waves.
[0211] In some embodiments, the terminal or base station can achieve sensing through the form of a self-transmitted and self-received sensing reference signal (sensing RS). For this single-site sensing, determining the parameter information of the sensing reference signal is a pressing technical problem to be solved.
[0212] To address this, the present disclosure proposes a communication scheme that, for a single station such as a terminal or base station, can determine the parameter information corresponding to the sensing reference signal based on first information for the sensing reference signal it transmits and receives itself, thus solving the technical problem of how to determine the parameter information of the sensing reference signal.
[0213] Figure 2A is a schematic diagram illustrating a method for determining parameters according to an embodiment of the present disclosure. To illustrate an implementation of the communication system of Figure 1A, as shown in Figure 2A, the method includes the following steps:
[0214] Step S2101: The terminal obtains the first information.
[0215] In some embodiments, the terminal can achieve sensing through self-transmitted and self-received sensing reference signals (sensing RS). For example, the terminal includes at least two antennas, one antenna a for transmitting sensing reference signals and the other antenna b for receiving sensing reference signals. The terminal transmits sensing reference signals to the sensing object through antenna a, and receives the sensing reference signals transmitted by antenna a and the corresponding sensing reference signals reflected by the sensing object through antenna b. Then, based on the two sensing reference signals received by antenna b, the terminal performs sensing measurements on the sensing object to obtain the corresponding sensing results.
[0216] In some embodiments, the first information can be used to determine parameter information of the sensed reference signal.
[0217] In some examples, the parameter information of the sensing reference signal can be used by the terminal to automatically transmit and receive sensing reference signals for the sensing object.
[0218] In some examples, the parameter information of the sensing reference signal can be explicitly carried by the first information, or implicitly determined by the mapping relationship of the first information.
[0219] In some embodiments, the terminal may determine the first information according to a protocol predefined.
[0220] In some embodiments, the terminal may receive the first information sent by the access network device. In some examples, the access network device may be the access network device corresponding to the terminal.
[0221] In some examples, the access network device may be a base station or a sensing management entity, etc.
[0222] In some embodiments, the terminal may jointly determine the first information based on a protocol predefined parameter and an instruction sent by the access network device. For example, the protocol predefined a plurality of candidate parameter information, and the terminal determined the parameter information of the sensing reference signal from these candidate parameter information according to the instruction sent by the access network device.
[0223] In some embodiments, the terminal may determine the first information based on implementation, and then determine the parameter information of the sensing reference signal. For example, the terminal may determine whether it is necessary to send a sensing reference signal to achieve sensing based on actual needs. If it is necessary to send a sensing reference signal, the terminal may determine the first information on its own, and then determine the parameter information of the sensing reference signal, and then generate and send the sensing reference signal using the parameter information.
[0224] In some embodiments, the first information may include at least one of the following:
[0225] At least one reference signal sequence; constraints on the reference signal sequence; at least one beam; at least one transmit power information; open-loop and closed-loop power control information; constraints on the transmit power information; at least one waveform; indication of whether to use a non-communication waveform; indication of whether to use a communication waveform; at least one guard bandwidth; at least one subcarrier spacing; reference for the value of the subcarrier spacing.
[0226] In step S2102, the terminal determines the parameter information corresponding to the sensing reference signal based on the first information.
[0227] In some embodiments, the parameter information of the sensed reference signal may include at least one of the following A1 to F1:
[0228] A1. Reference signal sequence (RS sequence), which can be used to generate a sensing reference signal.
[0229] B1. Beam information of the sensing reference signal.
[0230] C1. Sensing the transmission power information of the reference signal.
[0231] D1. Perceive the waveform information of the reference signal.
[0232] E1, the guard band of the sensing reference signal in the frequency domain.
[0233] F1, Subcarrier Spacing (SCS) of the Sensing Reference Signal in the Frequency Domain.
[0234] In step S2103, the terminal sends a sensing reference signal to the sensing object based on the parameter information and receives the sensing reference signal reflected by the sensing object.
[0235] In some embodiments, the first information for determining the reference signal sequence (A1) includes at least one of the following:
[0236] At least one reference signal sequence; constraints on the reference signal sequence.
[0237] In some embodiments, for a terminal-based single-site sensing service, the terminal can automatically transmit and receive sensing reference signals on a first time-frequency resource. The first time-frequency resource can be configured to the terminal by a network device. The terminal can determine the sensing reference signals to be transmitted based on at least one RS sequence.
[0238] In some examples, the protocol predefines multiple RS sequences. Access network devices (such as base stations or sensing management entities) configure or notify the terminal of one or more RS sequences via a first signaling instruction. These one or more RS sequences are used by the terminal to generate sensing RS sequences. The first signaling instruction can be at least one of Downlink Control Information (DCI), Media Access Control (MAC) Control Element (CE), or Radio Resource Control (RRC) signaling.
[0239] For example, the access network device configures the terminal to generate the sensing RS sequence via the first parameter of the RRC signaling. The protocol predefines candidate RS sequences as sequence 0, sequence 1, sequence 2, and sequence 3. The first parameter contains two indicator bits: 00 represents sequence 0, 01 represents sequence 1, 10 represents sequence 2, and 11 represents sequence 3. The terminal then determines one or more RS sequences from these candidate RS sequences based on the first parameter to generate the sensing RS.
[0240] In some examples, the access network device configures or notifies the terminal of constraints for the RS sequence via a first signaling instruction. These constraints may include at least one of sequence type, sequence length, autocorrelation, and cross-correlation. The terminal selects an RS sequence based on these constraints. This RS sequence is used by the terminal to generate a sensing RS. The first signaling instruction is at least one of DCI, MAC CE, and RRC signaling.
[0241] In some examples, the protocol predefines constraints on the RS sequence, which may include at least one of sequence type, sequence length, autocorrelation, and cross-correlation. The terminal selects an RS sequence based on these constraints. This RS sequence is used by the terminal to generate the sensing RS.
[0242] In some examples, the protocol predefines a unique RS sequence, and the terminal generates a sensing RS based on this RS sequence.
[0243] In some examples, the protocol predefines multiple RS sequences, from which the terminal selects any one or more RS sequences to generate a sensing RS.
[0244] In some examples, the protocol does not define an RS sequence for single-site sensing services; the terminal determines the RS sequence based on the implementation and generates a sensing RS.
[0245] In some embodiments, the first information for determining the beam information (B1) of the sensing reference signal may include at least one beam.
[0246] In some embodiments, for a terminal-based single-site sensing service, the terminal automatically transmits and receives sensing RS on a first time-frequency resource. This first time-frequency resource can be configured for the terminal by a network device. The terminal needs to determine at least one beam to transmit the sensing RS. This beam can be controlled by a base station, network, or sensing management entity, or it may be related to the terminal implementation.
[0247] In some examples, the access network device configures or notifies the terminal of one or more beams via a second signaling, which are used by the terminal to send a sensing RS. The second signaling can be at least one of DCI, MAC CE, and RRC.
[0248] For example, a base station, network, or sensing management entity configures the beam for sending the sensing RS via the second parameter of the RRC signaling. The protocol predefines candidate beams: beam 0, beam 1, beam 2, and beam 3. This second parameter contains two indicator bits: 00 for beam 0, 01 for beam 1, 10 for beam 2, and 11 for beam 3. The terminal then determines at least one beam from the candidate beams based on the second parameter for sending the sensing RS.
[0249] In some examples, the protocol predefines a single beam for sending sensing RS, through which the terminal sends sensing RS.
[0250] In some examples, the protocol predefines multiple beams for sending sensing RS, and the terminal selects any one or more beams to send sensing RS.
[0251] In some examples, the protocol does not define a beam for single-site sensing services; the terminal determines the beam based on the implementation and sends the sensing RS.
[0252] In some embodiments, the transmit power information (C1) of the sensed reference signal may include at least one of the following A2 to D2:
[0253] A2. Transmission power used, such as the transmission power used to transmit the sensing reference signal.
[0254] B2. Maximum Transmission Power (TPmax): The transmission power used to transmit the sensing reference signal must be less than or equal to this maximum value.
[0255] C2. Initial transmission power, which can be used to determine the actual transmission power of the sensing reference signal.
[0256] D2. Allowable transmission power range, such as the network's allowed transmission power range. The transmission power of the sensing reference signal needs to be configured within this transmission power range. For example, TPmax needs to be less than the maximum value (Pcmax) of this transmission power range. This Pcmax satisfies the network indicated power limit, and the power backoff does not exceed the threshold.
[0257] In some embodiments, the first information for determining the transmission power information (C1) of the sensing reference signal includes at least one of the following:
[0258] At least one transmission power; open-loop and closed-loop power control information (used to determine the transmission power); at least one maximum transmission power (MAX Transmission power, TPmax); and constraints on the maximum transmission power.
[0259] In some embodiments, for terminal-only sensing services, the terminal transmits and receives sensing RS on a first time-frequency resource. This first time-frequency resource is configured to the terminal by the network device. The terminal needs to determine the transmission power (A2) of the transmitted sensing RS.
[0260] In some examples, the protocol predefines multiple transmission powers. Access network devices (such as base stations) configure or notify the terminal of one or more transmission powers via third signaling. These one or more transmission powers are used by the terminal to send sensing RS. This third signaling can be at least one of DCI, MAC CE, and RRC.
[0261] For example, the base station configures the transmission power for the terminal to send sensing RS via the third parameter of the RRC signaling. The protocol predefines candidate transmission powers: Transmission power 0, Transmission power 1, Transmission power 2, and Transmission power 3. The third parameter contains two indicator bits: 00 for Transmission power 0, 01 for Transmission power 1, 10 for Transmission power 2, and 11 for Transmission power 3. The terminal then determines one or more transmission powers from these candidate transmission powers based on the third parameter for sending the sensing RS.
[0262] In some examples, the access network device configures or notifies the terminal via third signaling to determine open-loop and closed-loop power control information for the transmission power, thereby enabling the terminal to determine the transmission power based on the open-loop and closed-loop power control information. This transmission power is used by the terminal to transmit the sensing RS. The third signaling is at least one of DCI, MAC CE, and RRC.
[0263] In some examples, the protocol predefines a single transmission power, and the terminal sends a sensing RS based on that transmission power.
[0264] In some examples, the protocol predefines multiple transmission powers, from which the terminal selects any one or more transmission powers and then uses the selected one or more transmission powers to send the sensing RS.
[0265] In some examples, the protocol does not define the transmission power for single-site sensing services; the terminal determines the transmission power based on the implementation and sends the sensing RS.
[0266] In some embodiments, for terminal-based single-site sensing services, the terminal transmits and receives sensing RS on a first time-frequency resource. This first time-frequency resource is configured to the terminal by the network device. The terminal needs to determine the maximum value TPmax (B2) of the transmission power of the transmitted sensing RS. The transmission power of the terminal transmitting the sensing RS must not exceed TPmax.
[0267] In some examples, the protocol predefines multiple TPmaxes. Access network devices (such as base stations) configure or notify the terminal of one or more TPmaxes via fourth signaling. These one or more TPmaxes are used by the terminal to send sensing RS. The fourth signaling is at least one of DCI, MACCE, and RRC.
[0268] For example, the base station configures the terminal to send the TPmax of the sensing RS via the fourth parameter of the RRC signaling. The protocol predefines candidate TPmax as TPmax 0, TPmax 1, TPmax 2, and TPmax 3. The fourth parameter contains two indicator bits: 00 represents TPmax 0, 01 represents TPmax 1, 10 represents TPmax 2, and 11 represents TPmax 3. The terminal can then determine the TPmax to send the sensing RS based on the fourth parameter.
[0269] In some examples, the access network device configures or notifies the terminal of a restriction on TPmax via fourth signaling, which limits the maximum value of TPmax. The terminal selects TPmax based on this restriction. TPmax is used by the terminal to send the sensing RS. The fourth signaling is at least one of DCI, MAC CE, and RRC.
[0270] In some examples, the protocol predefines a constraint on TPmax, which limits the maximum value of TPmax. The terminal selects TPmax based on the constraint. TPmax is used by the terminal to send the sensing RS.
[0271] In some examples, the protocol predefines a single TPmax, and the terminal sends a sensing RS based on this TPmax.
[0272] In some examples, the protocol predefines multiple TPmaxes, and the terminal selects any one or more TPmaxes from them to send the sensing RS.
[0273] In some examples, the protocol does not define TPmax for single-site sensing services; the terminal determines TPmax based on the implementation and sends a sensing RS.
[0274] In some embodiments, if the strength of the sensing reference signal received by the terminal is less than the strength threshold, the terminal sends a first request to the access network device. The first request is used to request an increase in the transmission power information of the sensing reference signal.
[0275] In some examples, when the strength of the sensed reference signal received by the terminal is less than a first threshold, a first request can be sent to the access network device to request an increase in initial transmission power. For instance, when the terminal determines that the received sensed reference signal is weak, it can send a first request to the access network device, such as a base station or a sense management entity, to request that the access network device increase its initial transmission power (e.g., referred to as the first power). In one example, the terminal can determine the signal strength by the received power of the sensed reference signal; when it falls below a certain power threshold, the terminal sends a first request to increase the first power. This strength threshold can be predefined by the protocol, configured by the base station, network, or sense management entity, or determined based on the terminal implementation.
[0276] In some examples, when the strength of the sensed reference signal received by the terminal is less than a strength threshold, the terminal can update its initial transmit power and send the increased initial transmit power to the access network device. For example, when the terminal determines that the received sensed reference signal is weak, it can increase the initial transmit power (e.g., referred to as the first power) and send the increased result to the access network device.
[0277] In some examples, when the strength of the sensed reference signal received by the terminal is less than a strength threshold, a first request can be sent to the access network device. This first request requests an increase in the allowed configurable transmission power range. For example, when the terminal determines that the received sensed reference signal is weak, it can send a first request to the access network device, such as a base station or a sense management entity, requesting that the access network device increase the maximum value (Pcmax) of the allowed configurable transmission power range. In one example, the terminal can determine the signal strength by the received power of the sensed reference signal. When it falls below a certain power threshold, the terminal sends a first request to increase Pcmax. This strength threshold can be predefined by the protocol, configured by the base station, network, or sense management entity, or determined based on the terminal implementation.
[0278] In some examples, when the strength of the sensed reference signal received by the terminal is less than a strength threshold, the terminal can automatically update the allowed transmit power range and send the corresponding update result to the access network device. For example, when the terminal determines that the received sensed reference signal is weak, it can automatically increase Pcmax and report the increased result through a Power Headroom Report (PHR) to notify the network side. In one example, the terminal determines the signal strength based on the received power of the sensed signal; when it falls below a certain power threshold, the terminal increases Pcmax.
[0279] In some embodiments, when the number of times the terminal fails to decode the sensing reference signal reaches a threshold, the terminal sends a first request to the access network device. The first request is used to request an increase in the transmission power information of the sensing reference signal.
[0280] In some examples, when the number of times the terminal continuously fails to decode the sensing reference signal reaches a threshold, a first request can be sent to the access network device. This first request requests an increase in initial transmission power. For example, when the terminal determines that it has continuously failed to decode the sensing reference signal, it can send a first request to the access network device, such as a base station or a sensing management entity, requesting the network or sensing management entity to increase the first power. In one example, when the terminal fails to decode the sensing reference signal n times consecutively, the terminal sends the first request to increase the first power. This value of n (i.e., the second threshold) can be predefined by the protocol, configured by the base station, network, or sensing management entity, or determined based on the terminal implementation.
[0281] In some examples, when the number of times the terminal continuously fails to decode the sensing reference signal reaches a second threshold, the terminal can automatically update its initial transmit power and send the increased initial transmit power to the access network device. For example, when the number of times the terminal continuously fails to decode the sensing reference signal reaches a threshold, it can automatically increase its initial transmit power (e.g., referred to as the first power) and send the increased result to the access network device.
[0282] In some examples, when the number of times a terminal continuously fails to decode the sensing reference signal reaches a threshold, a first request can be sent to the access network device. This first request is used to request an update to the allowed transmission power range. For example, when the terminal determines that it has continuously failed to decode the sensing reference signal, it can send a first request to the access network device, such as a base station or a sensing management entity, to request the network or sensing management entity to increase Pcmax. In one example, when the terminal fails to decode the sensing reference signal n times consecutively, the terminal sends a first request to increase Pcmax. This value of n (i.e., the threshold) can be predefined by the protocol, configured by the base station, network, or sensing management entity, or determined based on the terminal implementation.
[0283] In some examples, when the number of times a terminal continuously fails to decode the sensing reference signal reaches a threshold, the terminal can automatically update the allowed transmission power range and send the corresponding update result to the access network device. For example, when the number of times a terminal continuously fails to decode the sensing reference signal reaches the threshold, it can automatically increase Pcmax and report the increased result through PHR to notify the network side.
[0284] In some embodiments, when the terminal's sensing accuracy is less than an accuracy threshold, the terminal may receive a first indication sent by the access network device, which is used to increase the transmission power information of the sensing reference signal.
[0285] In some examples, when the Sensing Function (SF) network element determines that the terminal's sensing accuracy is less than an accuracy threshold, the access network equipment can control the terminal to increase its initial transmission power. This accuracy threshold can be determined by predefined protocols, etc.
[0286] In some examples, when the SF network element determines that the terminal's sensing accuracy is less than the accuracy threshold, it can control the terminal to update the allowed configured transmit power range through the access network equipment, such as controlling the terminal to increase Pcmax. This accuracy threshold can be determined by protocol predefinition, etc.
[0287] In some embodiments, the first information for determining the waveform information (D1) of the sensed reference signal may include at least one of the following:
[0288] At least one waveform; an indication of whether a non-communication waveform is used; an indication of whether a communication waveform is used.
[0289] In some embodiments, for terminal-based single-site sensing services, the terminal automatically transmits and receives sensing RS on a first time-frequency resource. This first time-frequency resource is configured to the terminal by the network device. The terminal needs to determine the waveform information of the sensing RS.
[0290] In some examples, the access network device configures or notifies the terminal of one or more Waveforms via the fifth signaling, which are used by the terminal to transmit the sensing RS. This fifth signaling can be at least one of DCI, MAC CE, and RRC. For example, the base station configures the Waveform for the terminal to transmit the sensing RS via the fifth parameter of the RRC signaling. The protocol predefines candidate Waveforms as Waveform 0, Waveform 1, Waveform 2, and Waveform 3. This fifth parameter contains two indicator bits: 00 represents Waveform 0, 01 represents Waveform 1, 10 represents Waveform 2, and 11 represents Waveform 3. The terminal can then determine one or more Waveforms based on the fifth parameter for transmitting the sensing RS.
[0291] In some examples, the access network device configures or notifies the terminal via the fifth signaling whether to send a sensing RS using a non-communication waveform, or whether to use one or more communication waveforms. The fifth signaling can be at least one of DCI, MAC CE, and RRC.
[0292] In some examples, the protocol predefines a single Waveform for sending the sensing RS, through which the terminal sends the sensing RS.
[0293] In some examples, the protocol predefines multiple Waveforms for sending sensing RS, and the terminal selects any one or more Waveforms to send sensing RS.
[0294] In some examples, the protocol does not define a Waveform for single-site sensing services; the terminal determines the Waveform based on the implementation and sends the sensing RS.
[0295] In some embodiments, the first information for determining the guard bandwidth (E1) of the sensing reference signal includes: at least one guard bandwidth.
[0296] In some embodiments, for terminal-based single-site sensing services, the terminal automatically transmits and receives sensing RS on a first time-frequency resource. The first time-frequency resource is configured to the terminal by the network device. Furthermore, to ensure that the sensing service is not interfered with by other signals, and to prevent power leakage when high-capacity terminals transmit sensing RS, a guard band exists in the frequency domain.
[0297] In some examples, the protocol predefines a unique guard band located on either side of the frequency domain within the first time-frequency resource. The guard band can be several frequency domain units.
[0298] In some examples, the protocol predefines multiple Guard bands, and the terminal selects any one of the Guard bands to send the sensing RS. This Guard band is located on both sides of the frequency domain within the first time-frequency resource.
[0299] In some examples, the protocol predefines multiple guard bands. Access network devices configure or notify terminals of a guard band via sixth signaling, which is located on both sides of the frequency domain within the first time-frequency resource. This guard band can be several frequency domain elements. The sixth signaling can be at least one of DCI, MAC CE, and RRC.
[0300] In some embodiments, the first information for determining the subcarrier spacing (F1) of the sensed reference signal includes at least one of the following:
[0301] At least one subcarrier spacing (SCS); the value of the subcarrier spacing is referenced.
[0302] In some embodiments, for terminal-based single-site sensing services, the terminal automatically transmits and receives sensing RS on a first time-frequency resource. The first time-frequency resource is configured to the terminal by the network device. The terminal determines the SCS in the frequency domain of the first time-frequency resource.
[0303] In some examples, the protocol predefines a unique SCS, which is used to transmit the sensing RS. This SCS can take values such as 15, 30, 60, 120, 240, 480, 960 kHz, etc.
[0304] In some examples, the protocol predefines multiple SCSs, from which the terminal selects any one to transmit the sensing RS. The SCS can take values such as 15, 30, 60, 120, 240, 480, or 960 kHz. For instance, assuming all OFDM symbols carrying the sensing RS are allocated to the terminal for sensing RS transmission, since there is no need for multiplexing, the terminal can decide the SCS independently.
[0305] In some examples, the protocol predefines multiple SCSs. The access network device configures or notifies the terminal of an SCS via the seventh signaling. The SCS can have values of 15, 30, 60, 120, 240, 480, 960 kHz, etc., and is used by the terminal to send the sensing RS. The seventh signaling can be at least one of DCI, MAC CE, and RRC.
[0306] In some examples, the protocol predefines a reference value for the SCS (Search Server Classification), and the SCS value is determined based on this reference. This SCS is used by the terminal to transmit the sensing RS (Search Server Reading). For example, the SCS may be the same as the SCS configured in the reference, or the same as the maximum value of the SCS in the reference, or the same as the minimum value of the SCS in the reference. The reference value may include at least one of the following: initial BWP (Background Control Panel), active BWP (Active Background Control Panel), serving cell configuration, primary cell configuration, and secondary cell configuration. The SCS value can be 15, 30, 60, 120, 240, 480, 960 kHz, etc.
[0307] This disclosure proposes a communication scheme in which, for a sensing reference signal transmitted and received by the terminal itself, the terminal can determine the parameter information corresponding to the sensing reference signal based on first information, thus solving the technical problem of how to determine the parameter information of the sensing reference signal.
[0308] Figure 2B is a schematic diagram illustrating a method for determining parameters according to an embodiment of the present disclosure. To illustrate the implementation of the communication system of Figure 1B, taking a base station as an example of an access network device, as shown in Figure 2B, the method includes the following steps:
[0309] In step S2201, the base station obtains the first information.
[0310] In some embodiments, the base station can achieve sensing through self-transmitted and self-received sensing reference signals (sensing RS). For example, the base station includes at least two antennas, one antenna c for transmitting sensing reference signals and the other antenna d for receiving sensing reference signals. The base station transmits sensing reference signals to the sensing object through antenna c, and receives the sensing reference signals transmitted by antenna c and the corresponding sensing reference signals reflected by the sensing object through antenna d. Then, based on the two sensing reference signals received by antenna d, the base station performs sensing measurements on the sensing object to obtain the corresponding sensing results.
[0311] In some embodiments, the first information can be used to determine parameter information of the sensed reference signal.
[0312] In some examples, the parameter information of the sensing reference signal can be used by the base station to automatically transmit and receive sensing reference signals for the sensing object.
[0313] In some examples, the parameter information of the sensing reference signal can be explicitly carried by the first information, or implicitly determined by the mapping relationship of the first information.
[0314] In some embodiments, the base station may determine the first information according to a protocol predefined.
[0315] In some embodiments, the base station may receive the first information sent by the core network equipment.
[0316] In some examples, the core network equipment may be SF network elements, etc.
[0317] In some embodiments, the base station may jointly determine the first information based on a protocol predefined parameter and an instruction sent by the core network device. For example, the protocol predefined a plurality of candidate parameter information, and the base station determined the parameter information of the sensing reference signal from these candidate parameter information based on the instruction sent by the core network device.
[0318] In some embodiments, the base station may determine the first information based on implementation, and then determine the parameter information of the sensing reference signal. For example, the base station determines whether it needs to transmit the sensing reference signal to achieve sensing based on actual needs. If it needs to transmit the sensing reference signal, it can determine the first information itself, and then determine the parameter information of the sensing reference signal, and then generate and transmit the sensing reference signal through the parameter information.
[0319] In some embodiments, the first information may include at least one of the following:
[0320] At least one reference signal sequence; constraints on the reference signal sequence; at least one beam; at least one transmit power information; open-loop and closed-loop power control information; constraints on the transmit power information; at least one waveform; indication of whether to use a non-communication waveform; indication of whether to use a communication waveform; at least one guard bandwidth; at least one subcarrier spacing; reference for the value of the subcarrier spacing.

[0333] In some examples, the protocol predefines constraints on the RS sequence, including at least one of sequence type, sequence length, autocorrelation, and cross-correlation. The base station selects the RS sequence based on these constraints. The RS sequence is used by the base station to generate the sensing RS.
[0334] In some examples, the protocol predefines a unique RS sequence, and the base station generates a sensing RS based on this RS sequence.
[0335] In some examples, the protocol predefines multiple RS sequences, from which the base station selects any one or more RS sequences to generate a sensing RS.
[0336] In some examples, the protocol does not define an RS sequence for single-site sensing services; the base station determines the RS sequence based on the implementation and generates the sensing RS.
[0337] In some embodiments, the first information for determining the beam information (B3) of the sensing reference signal may include at least one beam.
[0338] In some embodiments, for base station-based single-site sensing services, the base station automatically transmits and receives sensing RS on the first time-frequency resource. The base station needs to determine at least one beam for transmitting sensing RS.
[0339] In some examples, the protocol predefines a single beam for transmitting sensing RS, through which the base station transmits sensing RS.
[0340] In some examples, the protocol predefines multiple beams for transmitting sensing RS, and the base station selects any one or more beams from these beams to transmit sensing RS.
[0341] In some examples, the protocol does not define a beam for single-site sensing services; the base station determines the beam based on the implementation and sends sensing RS.
[0342] In some embodiments, the transmit power information (C3) of the sensed reference signal may include at least one of the following A4 to C4:
[0343] A4. Transmission power used, such as the transmission power used to transmit the sensing reference signal.
[0344] B4. Maximum Transmission Power (TPmax): The transmission power used to transmit the sensing reference signal must be less than or equal to this maximum value.
[0345] C4. Initial transmission power, which can be used to determine the actual transmission power of the sensing reference signal.
[0346] In some embodiments, the first information for determining the transmission power information (C3) of the sensing reference signal includes at least one of the following:
[0347] At least one transmission power; open-loop and closed-loop power control information (used to determine the transmission power); at least one maximum transmission power (MAX Transmission power, TPmax); and the limiting conditions for the maximum transmission power.
[0348] In some embodiments, for base station-based single-site sensing services, the base station transmits and receives sensing RS on the first time-frequency resource. The base station needs to determine the transmission power (A4) of the transmitted sensing RS.
[0349] In some examples, the protocol predefines open-loop and closed-loop power control information for the transmission power, allowing the base station to determine the transmission power based on this information. This transmission power is used by the base station to transmit the sensing RS.
[0350] In some examples, the protocol predefines a single transmission power, and the base station sends a sensing RS based on that transmission power.
[0351] In some examples, the protocol predefines multiple transmission powers, from which the base station selects any one or more transmission powers and then uses the selected one or more transmission powers to transmit the sensing RS.
[0352] In some examples, the protocol does not define the transmission power for single-site sensing services; the base station determines the transmission power based on the implementation and sends the sensing RS.
[0353] In some embodiments, for a single-site sensing service, the base station automatically transmits and receives sensing RS on the first time-frequency resource. The base station needs to determine the maximum value TPmax (B4) of the transmission power of the transmitted sensing RS. The transmission power of the base station transmitting the sensing RS must not exceed TPmax.
[0354] In some examples, the protocol predefines a constraint on TPmax, which limits the maximum value of TPmax. The base station selects TPmax based on the constraint. TPmax is used by the base station to transmit the sensing RS.
[0355] In some examples, the protocol predefines a single TPmax, and the base station sends a sensing RS based on this TPmax.
[0356] In some examples, the protocol predefines multiple TPmaxes, and the base station selects any one or more TPmaxes from them to send the sensing RS.
[0357] In some examples, the protocol does not define TPmax for single-site sensing services; the base station determines TPmax based on the implementation and sends a sensing RS.
[0358] In some embodiments, when the strength of the sensing reference signal received by the access network device is less than the strength threshold, the base station sends a second request to the core network device. The second request is used to request an increase in the transmission power information of the sensing reference signal.
[0359] In some examples, when the strength of the sensed reference signal received by the base station is less than a strength threshold, it can send a first request to the core network equipment. This first request requests an increase in initial transmission power. For example, when the base station determines that the received sensed reference signal is weak, it can send a first request to the SF network element, requesting the SF network element to agree to increase its initial transmission power (e.g., the first power). In one example, the base station can determine the signal strength by the received power of the sensed reference signal. When it falls below a certain power threshold, the base station sends a first request to increase the first power. This first threshold can be predefined by the protocol or determined based on the base station implementation.
[0360] In some examples, when the strength of the sensed reference signal received by the base station is less than a strength threshold, the base station can automatically update its initial transmit power and send the updated result to the core network equipment. For example, when the base station determines that the received sensed reference signal is weak, it can automatically increase the initial transmit power (e.g., referred to as the first power) and send the increased result to the core network equipment.
[0361] In some embodiments, when the number of times the access network device fails to decode the sensing reference signal reaches a threshold, a second request is sent to the core network device. The second request is used to request an increase in the transmission power information of the sensing reference signal.
[0362] In some examples, when the number of consecutive failures to decode the Sensing Reference Signal (SRS) by a base station reaches a threshold, a first request can be sent to the core network equipment. This first request requests an update to the initial transmission power. For example, when the base station determines that it has continuously failed to decode the SRS, it can send a first request to the SF network element, requesting the SF network element to agree to increase the initial power. In one example, when the base station has consecutively failed to decode the SRS n times, it sends a first request to increase the initial power. This value of n (i.e., the threshold) can be predefined by the protocol or determined based on the base station implementation.
[0363] In some examples, when the number of times a base station continuously fails to decode the sensing reference signal reaches a threshold, the base station can automatically update its initial transmit power and send the updated result to the core network equipment. For example, when the number of times a base station continuously fails to decode the sensing reference signal reaches a second threshold, it can automatically increase its initial transmit power (e.g., referred to as the first power) and send the increased result to the core network equipment.
[0364] In some embodiments, when the sensing accuracy of the access network device is less than the accuracy threshold, a second indication sent by the core network device is received, which is used to increase the transmission power information of the sensing reference signal.
[0365] In some examples, when an SF network element determines that the base station's sensing accuracy is less than an accuracy threshold, it can control the base station to increase its initial transmission power. This accuracy threshold can be determined by protocol predefinition, etc.
[0366] In some embodiments, the first information for determining the waveform information (D3) of the sensing reference signal may include at least one waveform.
[0367] In some embodiments, for a single-site sensing service, the base station automatically transmits and receives sensing RS on the first time-frequency resource. The base station needs to determine the waveform information of the sensing RS.
[0368] In some examples, the protocol predefines a single Waveform for transmitting the sensing RS, through which the base station transmits the sensing RS.
[0369] In some examples, the protocol predefines multiple Waveforms for transmitting sensing RS, and the base station selects any one or more Waveforms from these to transmit sensing RS.
[0370] In some examples, the protocol does not define a Waveform for single-site sensing services; the base station determines the Waveform based on its implementation and sends the sensing RS.
[0371] In some embodiments, the first information for determining the guard bandwidth (E3) of the sensing reference signal includes: at least one guard bandwidth.
[0372] In some embodiments, for a single-site sensing service, the base station automatically transmits and receives sensing RS on the first time-frequency resource. Furthermore, to ensure that the sensing service is not interfered with by other signals, and to prevent power leakage when a high-capacity base station transmits sensing RS, a guard band exists in the frequency domain.
[0373] In some examples, the protocol predefines a unique guard band located on either side of the frequency domain within the first time-frequency resource. The guard band can be several frequency domain units.
[0374] In some examples, the protocol predefines multiple Guard bands, and the base station selects any one of the Guard bands to send the sensing RS. This Guard band is located on both sides of the frequency domain within the first time-frequency resource.
[0375] In some embodiments, the first information for determining the subcarrier spacing (F3) of the sensed reference signal includes at least one of the following:
[0376] At least one subcarrier spacing (SCS); the value of the subcarrier spacing is referenced.
[0377] In some embodiments, for a single-site sensing service, the base station automatically transmits and receives sensing RS on the first time-frequency resource. The base station determines the SCS in the frequency domain of the first time-frequency resource.
[0378] In some examples, the protocol predefines a unique SCS, which is used to transmit the sensing RS. This SCS can take values such as 15, 30, 60, 120, 240, 480, 960 kHz, etc.
[0379] In some examples, the protocol predefines multiple SCSs, from which the base station selects any one to transmit the sensing RS. The SCS can take values such as 15, 30, 60, 120, 240, 480, or 960 kHz. For instance, assuming that all OFDM symbols carrying the sensing RS are allocated to the base station for sensing RS transmission, since there is no need for multiplexing, the base station can independently decide the SCS.
[0380] In some examples, the protocol predefines a reference value for the SCS (Search Server Classification), and the SCS value is determined based on this reference. This SCS is used by the base station to transmit the Sensing RS (Search Server Reading). For example, the SCS may be the same as the SCS configured in the reference, or the same as the maximum value of the SCS in the reference, or the same as the minimum value of the SCS in the reference. The reference value may include at least one of the following: initial BWP (Background-View Programming), active BWP (Active Background-View Programming), serving cell configuration, primary cell configuration, and secondary cell configuration. The SCS value can be 15, 30, 60, 120, 240, 480, 960 kHz, etc.

[0440] For terminal-based single-site sensing services, the terminal automatically transmits and receives sensing RS on the first time-frequency resource. The first time-frequency resource is configured to the terminal by the network device. The terminal needs to determine the maximum value TPmax (MAX Transmission power) of the transmitted sensing RS. The power of the terminal transmitting the sensing RS must not exceed TPmax. The determination of TPmax includes at least one of the following methods:
[0441] Method 1:
[0442] The protocol predefines multiple TPmaxes. The base station configures / notifies the UE of one or more TPmaxes via a first signaling signal. The one or more TPmaxes are used by the UE to send a sensing RS. The first signaling signal is at least one of DCI, MAC CE, and RRC.
[0443] In one example, the base station configures the UE to send the TPmax of the sensing RS via the first parameter of the RRC signaling.

[0456] For terminal-based single-site sensing services, the terminal automatically transmits and receives sensing RS on a first time-frequency resource. This first time-frequency resource is configured to the terminal by the network device. The terminal needs to determine the first power of the transmitted sensing RS.
