[0039] The technical solutions of this disclosure will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0040] It should be noted that, in this disclosure, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in this disclosure should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0041] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0042] In the description of this disclosure, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Furthermore, "at least one" means one or more, and "more than one" means two or more.

[0043] In an Integrated Sensing and Communication (ISAC) scenario, communication and sensing capabilities are integrated and symbiotic, endowing the network with the ability to both support communication and perceive the physical world. The sensing capability primarily focuses on wireless signal sensing to perform functions such as positioning, ranging, velocity measurement, imaging, detection, recognition, and environmental reconstruction. By transmitting and receiving sensing signals between sensing nodes or within a single sensing node, and analyzing the direct, reflected, scattered, and diffracted signals of the wireless signals, the perception results of the target or environment are obtained. Furthermore, wireless sensing measurements can be combined with radar, cameras, and other sensors to obtain the final perception results.

[0044] During the transmission of sensing signals, the transmission method may vary depending on factors such as antenna position, polarization direction, precoding, and beamforming. Determining the transmission method based on these factors for each transmission results in high overhead and slow transmission speed. To transmit sensing signals more efficiently and conveniently, one or more antenna ports can be defined for the sensing signal.

[0045] Currently, there is a lack of a communication method that defines the antenna port for sensing signals.

[0046] To address the aforementioned technical problems, this disclosure provides a communication method. Since the antenna port can serve different service needs and facilitates flexible resource allocation, by sending sensing configuration information, including relevant configuration information of the port corresponding to the sensing signal, to the first node, the first node can determine the port corresponding to the sensing signal and send the sensing signal based on that port. This enables flexible transmission and reception of the sensing signal, improves sensing performance, helps obtain more multi-dimensional sensing information, and enhances signal reliability.

[0047] The communication method provided in this disclosure can be applied to systems with various communication standards. For example, the systems to which the communication method provided in this disclosure is applicable include, but are not limited to, long-term evolution (LTE) systems, various versions based on LTE evolution, 5G systems, future mobile communication networks (such as 6G mobile communication networks), or multiple converged communication systems. Furthermore, the communication method provided in this disclosure can also be applied to future-oriented communication systems.

[0048] For example, the above communication method can be applied to, for example, Figure 1 In the aforementioned communication system, such as Figure 1 As shown, the communication system includes: a first node 101, a second node 102, and a third node 103.

[0049] The first node 101 is used to receive sensing configuration information from the second node; or, it is used to send sensing signals based on the sensing configuration information; the sensing configuration information includes the relevant configuration information of the port corresponding to the sensing signal.

[0050] The second node 102 is used to send sensing configuration information to the first node; the sensing configuration information includes relevant configuration information of the port corresponding to the sensing signal; or, it is used to receive sensing measurement results from the third node.

[0051] The third node 103 is used to receive the reflected signal of the sensing object, which is the sensing signal sent by the first node reflected by the sensing object; or, it is used to send the sensing measurement result to the second node, which is the measurement result of the reflected signal of the sensing object.

[0052] In some embodiments, the first node 101, the second node 102, and the third node 103 can all be referred to as sensing nodes. A sensing node refers to a node that participates in transmitting sensing signals, receiving / measuring sensing signals, or calculating sensing results.

[0053] In some embodiments, the sensing node can be a base station (BS) or a transmission reception point (TRP), a terminal, a positioning reference unit (PRU), or a sensing reference unit (SRU). Figure 1 Taking the first node 101 as a terminal, the second node 102 as a base station, and the third node 103 as a terminal as an example.

[0054] In some embodiments, the first node 101 may be referred to as the sensing signal transmitting node.

[0055] In some embodiments, the second node 102 may be a sensing node responsible for calculating the sensing results.

[0056] In some embodiments, the sensing node responsible for calculating the sensing results can be the core network, or the sensing core network.

[0057] In some embodiments, the third node 103 may be referred to as a sensing signal receiving node.

[0058] In some embodiments, the sensing modes include monostatic, bistatic (A transmits, B receives), and multistatic (multi-transmit, multi-receive). For example, base station monostatic (single-site sensing), base station A transmits, base station B receives (dual-site sensing), base station transmits, terminal receives, terminal transmits, base station receives, terminal monostatic, terminal A transmits, terminal B receives, and multistatic (multi-transmit, multi-receive).

[0059] In some embodiments, when the sensing mode is spontaneous and spontaneous, the first node 101 and the third node 102 can be the same node.

[0060] In some embodiments, the terminal can be a device with wireless transceiver capabilities, which can be deployed on land, including indoors or outdoors, handheld, wearable, or vehicle-mounted; it can also be deployed on water (such as on ships); and it can also be deployed in the air (e.g., on airplanes, balloons, and satellites). The terminal can be a mobile phone, tablet computer, computer with wireless transceiver capabilities, virtual reality (VR) terminal, augmented reality (AR) terminal, wireless terminal in industrial control, wireless terminal in self-driving, wireless terminal in remote medical care, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, wireless terminal in smart home, etc. The embodiments of this application do not limit the application scenarios. The term "terminal" can sometimes also refer to a user, user equipment (UE), access terminal, UE unit, UE station, mobile station, mobile station, remote station, remote terminal, mobile device, UE terminal, wireless communication device, UE agent, or UE device, etc., but the embodiments of this application do not limit this to these terms.

[0061] In some embodiments, the base station may be a base station in Long Term Evolution (LTE), Long Term Evolution Advanced (LTEA), or an evolved Node B (eNB or eNodeB), a base station device in a 5G network, or a base station in a future communication system. The base station may include various macro base stations, micro base stations, home base stations, wireless remote extensions, reconfigurable intelligent surfaces (RISs), routers, wireless fidelity (WIFI) devices, or various network-side devices such as primary cells and secondary cells.

[0062] It should be noted that, Figure 1 This is just an example framework diagram. Figure 1 The number of devices included and the names of each device are unlimited.

[0063] The application scenarios of the embodiments disclosed herein are not limited. The system architecture and business scenarios described in the embodiments of this disclosure are for the purpose of more clearly illustrating the technical solutions of the embodiments of this disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of this disclosure. As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of this disclosure are also applicable to similar technical problems.

[0064] The communication method provided in the embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0065] The communication method provided in this disclosure can be applied to... Figure 1 The first node 101 in the communication system shown. Figure 2 A flowchart of a communication method is shown, such as... Figure 2 As shown, the communication method includes the following S201-S202:

[0066] S201, Receive perception configuration information from the second node.

[0067] S202, Send sensing signals based on sensing configuration information.

[0068] The sensing configuration information includes the relevant configuration information of the port corresponding to the sensing signal.

[0069] In some embodiments, the sensing signal may also be referred to as the sensing reference signal.

[0070] It should be understood that since antenna ports can serve different service needs and facilitate flexible resource allocation, by sending sensing configuration information, including relevant configuration information of the port corresponding to the sensing signal, to the first node, the first node can determine the port corresponding to the sensing signal and send the sensing signal based on that port. This enables flexible transmission and reception of sensing signals, improves sensing performance, helps to obtain more dimensions of sensing information, and enhances signal reliability.

[0071] In some embodiments, the sensing signal is transmitted through a single antenna port (or a single port); there is an association between the single antenna port and the port corresponding to the communication signal (or other signal / channel besides the sensing signal). It should be noted that transmitting the sensing signal through a single antenna sensing port allows for the concentration of transmission power.

[0072] In some embodiments, the sensing configuration information may be carried in the sensing signal configuration signaling.

[0073] In another possible implementation, the sensing signal configuration signaling may not include configuration information about the antenna port, i.e., the port is not explicitly configured. In this case, the first node can determine the port corresponding to transmit the sensing signal based on a pre-configured / predefined / preset antenna port configuration method.

[0074] In some embodiments, a single antenna port is one of the ports corresponding to a communication signal; the sensing configuration information also includes at least one of the following: a port reference signal for a single antenna port (or a port reference for a sensing signal, or a reference for a sensing port, or a port reference), a resource index or resource set index for a communication signal, and a port number.

[0075] In one possible implementation, a mapping table can be established between the ports corresponding to the sensing signals and the ports corresponding to the communication signals. This mapping table determines the binding association between the sensing signal and a port corresponding to a specific communication signal. In another possible implementation, the set of candidate ports for the sensing signals can be consistent with the set of candidate ports for the communication signals. For example, if the communication signals use N ports, the sensing signal can be bound to port #n among those N ports.

[0076] In one possible implementation, the port reference can be a signal / channel other than the sensing signal. In another possible implementation, a reference signal / channel can be designated as the port reference. For example, the port corresponding to the Phase-Tracking Reference Signal (PT-RS), Channel State Information Reference Signal (CSI-RS), or Demodulation Reference Signal (DMRS) can be determined as the reference for the port corresponding to the sensing signal. In another possible implementation, the port of a communication signal with relatively good channel conditions can be selected and associated with the sensing signal, or a single port can be configured to be associated with the sensing signal.

[0077] In some embodiments, when the sensing configuration information includes a port reference signal but does not include a port number, the single antenna port is determined based on the port reference signal. In one possible implementation, the first node may autonomously select or select a port based on the port reference signal according to certain rules (e.g., optimal channel conditions) as the port for the sensing signal.

[0078] In some embodiments, when a single antenna port is determined based on a port reference signal, the method further includes: sending at least one of the following information to a second node and / or a third node: a timestamp, a time window, an index of the reference signal, and a port number of the single antenna port; the third node is used to receive the reflected signal of the sensed signal. Wherein, the timestamp is the timestamp of the first node transmitting the sensed signal. The time window is the time window during which the first node transmits the sensed signal. Thus, when the first node determines the single antenna port, information related to the first node's determination of the single antenna port can be communicated to the second node and / or the third node, enabling the second node to reliably receive / measure the reflected signal of the sensed signal, and / or the third node to reliably calculate the sensing result. For example, the timestamp or time window, as the transmission time or time interval of the sensed signal, can help determine the elapsed time when the reflected signal of the sensed signal is received by the third node. The index of the reference signal or the port number of the single antenna port can help determine the channel environment corresponding to the sensed signal, etc.

[0079] In some embodiments, if interference exists between the port of the sensing signal and the port of the communication signal, the transmission power of the sensing signal can be reduced to decrease the interference. Alternatively, the interference problem can be handled according to priority. For example, if the sensing signal has a higher priority, the transmission of other communication signals / channels can be adjusted; if the communication signal / channel has a higher priority, the transmission configuration of the sensing signal can be adjusted to reduce its impact on communication. The priority of the sensing signal can be explicitly configured (e.g., through signaling or message indication) or not explicitly configured (pre-configured / predefined for the respective priorities of the sensing signal and the communication signal).

[0080] In some embodiments, the sensing configuration information includes a candidate sensing port set; the candidate sensing port set is used to determine a single antenna port. It should be understood that the first node can select one port, or a single port, from the candidate sensing port set to transmit the sensing signal. In some embodiments, when the sensing signal is a periodic signal, the second node can configure an antenna port for the first node via Radio Resource Control (RRC) signaling (in this case, it can be understood that the candidate sensing port set includes only one antenna port). When the sensing signal is a semi-persistent or non-periodic signal, the second node can configure a set of candidate sensing ports for the first node via RRC signaling and activate a specific sensing port corresponding to the sensing signal using Media Access Control (MAC) Control Element (MAC CE) signaling.

[0081] In some embodiments, the sensing signal is transmitted through a single antenna port; the single antenna port does not coincide with the port corresponding to the communication signal. In this case, the port of the sensing signal can supplement the port of the communication signal. For example, the measurement result of a single-port sensing signal can be used to assist in channel measurement of the communication signal (e.g., Radio Resource Management Measurement (RRM) measurement, CSI measurement). For CSI measurement, assuming there are a total of 8 ports, ports 0-6 can be used for CSI measurement, and the sensing signal uses port 7. In this case, the measurement result of the sensing signal can be used to supplement the CSI measurement of the uncovered port 7.

[0082] In some embodiments, the ports of sensing signals are associated with the ports of communication signals, with the following application scenarios: 1. Sensing signal-assisted communication / communication-assisted sensing: The ports of sensing signals are associated with communication signals / channels; feedback information from the communication ports (such as CSI reports, Synchronization Signal Block (SSB) RRM measurements) is used to assist single-port sensing. 2. Sensing signal fusion design: To improve the maximum unambiguous speed and speed resolution of sensing speed estimation without increasing the resource occupancy of sensing signals, sensing signals can be fused with other communication signals / channels, wherein the ports of the sensing signals and the ports of the other signals / channels they are fused with are consistent.

[0083] It should be noted that sensing signals transmitted through multiple antenna ports (or multi-ports), or multi-port sensing signals, can support the acquisition of more dimensional information. For example, different ports can correspond to different polarizations to obtain sensing information corresponding to multiple polarization directions. For instance, in autonomous driving, it is necessary to detect the position, speed, and trajectory of multiple targets (vehicles, pedestrians). In this case, scanning with multiple ports and multiple beams can improve spatial resolution. For example, different ports in a multi-port system can serve different sensing tasks (port 1 detects targets, port 2 detects speed), allowing for the parallel acquisition of multi-dimensional data.

[0084] Multi-port sensing signals can also assist communication: sensing signals are equipped with multiple ports, making sensing more efficient and enabling the acquisition of sensing results from multiple ports to assist communication beams.

[0085] To address interference between sensing and communication signals, when they share spectrum resources, multi-port designs can achieve spatial domain isolation (e.g., different ports pointing to different users or regions) to reduce interference. Multi-port designs can allocate a subset of ports for sensing and another subset for communication.

[0086] For AI-based perception methods: By inputting multi-port perception data, multi-dimensional training data can be added, thereby improving the accuracy of AI perception.

[0087] In some embodiments, orthogonality between multiple ports can be achieved by at least one of the following:

[0088] Frequency division, where different ports occupy different frequency domain resources;

[0089] Time-division means that different ports occupy different time-domain resources;

[0090] Code division, for example, the frequency-domain orthogonal cover code (FD-OCC) used in demodulation reference signals.

[0091] For example, orthogonality between multiple ports can be achieved through frequency division and code division.

[0092] In some embodiments, when the sensing signal is transmitted through a multi-antenna port, the sensing configuration information may be the sensing reference signal configuration information provided by the sensing core network or base station to the first node, or it may be the information requested by the second node or third node from the base station or the first node for configuration.

[0093] In some embodiments, the sensing signal is transmitted through a multi-antenna port; the sensing configuration information includes at least one of the following: the port number corresponding to the multi-antenna port, the number of ports corresponding to the multi-antenna port, the port reference signal corresponding to the multi-antenna port, the orthogonal code type, the comb size, and the comb offset.

[0094] The port numbers corresponding to multiple antenna ports can be used to configure at least one port for transmitting sensing signals. In one possible implementation, sensing signals from the same port can be transmitted using different beams. In another possible implementation, one port can correspond to a different port, and different ports can use different beams for transmission. In some embodiments, for multiple port numbers corresponding to multiple antenna ports, the association between the port numbers and sensing signal transmission resources / resource sets / configurations can also be explicitly configured. For example, one or more ports can be configured to transmit the same sensing signal resource; or, one sensing signal resource set corresponds to one port, and two sensing signal resource sets can use different ports. In some embodiments, for multiple port numbers corresponding to multiple antenna ports, the association between the port numbers and sensing signal transmission resources / resources / configurations may not be configured. In this case, the first node sends at least one of the following to the second or third node: a timestamp, a time window, an index of the sensing signal resource / set / configuration, and a port number.

[0095] For example, the number of ports corresponding to multiple antenna ports can be N, where N is a positive integer.

[0096] The port reference signal corresponding to a multi-antenna port can also be called the port reference for the multi-antenna port. A port reference can specify a reference signal / channel. For example, the port of the phase-tracking reference signal can be the reference port of the sensing signal, and the sensing signal can be consistent with the port of the phase-tracking reference signal.

[0097] Orthogonal codes can also be called orthogonal cover codes (OCC). The types of orthogonal cover codes can include at least one of the following: non-code division multiplexing (no-CDM), frequency-domain orthogonal cover code (FD-OCC), time-domain orthogonal cover code (TD-OCC), and time / frequency-domain orthogonal cover code (TD / FD-OCC).

[0098] Comb size and comb offset: There is a correlation between the frequency domain resource units or time domain resource units of the comb configuration and the configuration of the orthogonal cover code.

[0099] In some embodiments, different ports or groups of ports in a multi-antenna port configuration correspond to different sensing areas. For example, one port or group of ports may be used for air sensing, while another port or group of ports may be used for ground sensing.

[0100] In some embodiments, different ports or different groups of ports in a multi-antenna port configuration correspond to different beam directions or polarization directions. For example, for a two-port sensing signal, the sensing signals from different ports are transmitted using different antenna polarization directions.

[0101] In some embodiments, the port resources for sensing signals can be based on service configuration.

[0102] In one possible implementation, the port configuration of the sensing signal can be associated with sensing requirements. For example, a single port could be used for basic target detection, while multiple ports could be used for environment reconstruction.

[0103] In one possible implementation, there is a mapping relationship between the ports or port groups in the multi-antenna port set and the ports corresponding to the communication signals. Alternatively, the ports / resources of the communication signals are divided into multiple port groups / resource groups, and each sensing signal port / resource has a mapping relationship with the communication signal port group / resource group. For example, if the number of sensing signal ports is 2 and the number of communication signal ports is 32, then the communication signal ports can be divided into two groups, each corresponding to one sensing signal port.

[0104] In one possible implementation, the port corresponding to the communication signal is the port corresponding to the target communication signal among multiple communication signals. Alternatively, the configuration of a multi-port sensing signal (such as a multi-port index or multiple resource indexes) can be associated with the port / resource of a specific communication signal. For example, a multi-port sensing signal can be associated with a single-port communication signal. Similarly, multiple sensing signal resource configurations can be associated with resource configurations of information other than the sensing signal itself.

[0105] In one possible implementation, the candidate port set for the sensing signal can be consistent with the port set for the communication signal.

[0106] In one possible implementation, the port of the sensing signal can supplement the port of the communication signal. In this case, the ports of the sensing signal and the communication signal do not overlap. For example, the measurement results of a multi-port sensing signal can be used to assist in channel measurements of the communication signal. For instance, for CSI measurements, assuming there are a total of 8 ports, ports 0-5 are available for CSI measurements, and the sensing signal uses ports 6 and 7. In this case, the measurement results of the sensing signal can be used to supplement CSI measurements on ports 6 and 7 that are not covered.

[0107] In some embodiments, the port configuration for sensing signals can be dynamically allocated based on service priority. In one possible implementation, the number of multi-antenna ports is positively correlated with the priority of the sensing service. For example, when the sensing priority is high, more port resources are allocated for sensing (e.g., half of the port resources are allocated for sensing). When the communication priority is high, more port resources are allocated for communication data decoding, and sensing only occupies a small number of port resources (e.g., using a single antenna port to transmit sensing signals).

[0108] In some embodiments, the method further includes: sending the capability information of the first node to the second node. It should be understood that by sending the capability information of the first node to the second node, the second node can be assisted in configuring resources for the first node to be used for sensing, making the resources configured for the first node more suitable for the capabilities of the first node.

[0109] In some embodiments, the capability information of the first node includes at least one of the following: the number of ports supported by the first node; whether it supports associating the antenna port of the sensing signal with the antenna port of the communication signal; and whether it supports determining the transmission port of the sensing signal based on a reference port or a support port reference signal. The number of ports supported by the first node enables the second node to determine the number of ports that the first node can use to transmit sensing signals. Whether it supports associating the antenna port of the sensing signal with the antenna port of the communication signal can be used to determine whether the first node can determine the port corresponding to the sensing signal based on the antenna port of the communication signal, or to determine whether the first node can use the port of the sensing signal as a supplement to the port of the communication signal. Whether it supports determining the transmission port of the sensing signal based on a reference port or a support port reference signal can be used to determine whether the first node has the capability to determine the transmission port of the sensing signal with reference to other signal transmission ports.

[0110] It should be noted that in the case of the first node transmitting and receiving sensing signals independently, there is a self-interference problem caused by signal transmission and reception. To address this problem, at least one of the following methods can be used:

[0111] Physical isolation is achieved by inserting an antenna isolation plate (or antenna isolation grid) between the transmitting and receiving antennas to improve the isolation between them. For example, ... Figure 3 The diagram shown is a schematic of an antenna isolation plate provided in an embodiment of this disclosure, including an antenna reference point (ARP) for the transmitting antenna (transmit x, Tx) of the transmitting antenna panel and an antenna reference point for the receiving antenna (receive x, Rx) of the receiving antenna panel. The transmitting antenna panel and the receiving antenna panel have M rows and N columns, respectively, with coordinates ranging from (0,0) to (M-1, N-1). M and N are both positive integers.

[0112] Interference can be reduced by designing different reference signals and waveforms.

[0113] Interference can be reduced by using different transmission modes; for example, time-division multiplexed pulse waves can be used to transmit and receive sensing signals.

[0114] In some embodiments, the first node supports self-transmitting and self-receiving sensing signals; the receiving antenna and transmitting antenna of the first node satisfy at least one of the following:

[0115] The transmit / receive isolation (or transmit / receive isolation) between the receiving antenna and the transmitting antenna is greater than or equal to a preset decibel;

[0116] The antenna reference point of the receiving antenna is identified in the same way as the antenna reference point of the transmitting antenna;

[0117] The distance between the antenna reference point of the receiving antenna and the antenna reference point of the transmitting antenna is less than or equal to a preset distance.

[0118] Transmit / receive isolation indicates the signal isolation capability between the receiving and transmitting antennas. It represents the percentage of the signal transmitted by the transmitting antenna that is captured by the receiving antenna, i.e., the proportion of the transmitted signal that leaks to the receiver through space, circuitry, or coupling paths. Higher transmit / receive isolation results in better isolation. A transmit / receive isolation greater than or equal to a preset decibel level between the receiving and transmitting antennas of the first node ensures that self-interference during the first node's self-transmitting and self-receiving of signals remains at a low level, guaranteeing accurate and reliable sensing.

[0119] An antenna reference point is a benchmark point in an antenna system used to calibrate the phase, position, and directional characteristics of a signal. It is used for signal phase measurement, determining the antenna's position in the coordinate system, and determining the beam direction. The antenna reference point of the receiving antenna is identified the same as that of the transmitting antenna, meaning that the receiving and transmitting antennas share the same physical reference.

[0120] If the distance between the antenna reference point of the receiving antenna and the antenna reference point of the transmitting antenna is less than or equal to a preset distance, it can ensure that random noise caused by the difference in physical reference between the transmitting and receiving antennas is at a low level, and can ensure that the transmission and reception isolation between the transmitting and receiving antennas is at a reliable level.

[0121] In some embodiments, the method further includes: if the first node supports self-transmitting and self-receiving sensing signals, sending first information to the second node, the first information being used to indicate information about the transmitting antenna of the first node, or information about the receiving antenna and transmitting antenna of the associated first node. This allows the second node to know the information about the transmitting antenna of the first node or the associated transmitting and receiving antennas, enabling the second node to more reliably schedule the first node to transmit and receive sensing signals. The receiving antenna in the associated receiving antenna and transmitting antenna of the first node is the antenna that receives the sensing signals transmitted by the transmitting antenna associated with that receiving antenna.

[0122] In some embodiments, the first information is used to indicate information about the associated receiving antenna and transmitting antenna; the first information includes at least one of the following:

[0123] Does there exist a pair or more pairs of receiving antenna reference points whose distance from the transmitting antenna reference point is less than a preset distance?

[0124] The antenna reference point of the receiving antenna is marked;

[0125] The identifier of the antenna reference point for the transmitting antenna;

[0126] Reference location information;

[0127] The location information of the antenna reference point of the receiving antenna;

[0128] The location information of the antenna reference point of the transmitting antenna;

[0129] The respective antenna reference points for the associated receiving and transmitting antennas.

[0130] Among them, the reference position information can be the position information of a certain reference antenna reference point.

[0131] The position information of the antenna reference point of the transmitting antenna can be the position relative to the antenna reference point of the receiving antenna.

[0132] The associated receiving and transmitting antennas can have a one-to-one correspondence or a one-to-many management relationship. For example, one transmitting antenna can be associated with multiple receiving antennas. One receiving antenna can be managed by multiple transmitting antennas. Transmitting and receiving antennas can be associated one-to-one.

[0133] In some embodiments, the first information is used to indicate information about the transmitting antenna of the first node; the first information includes at least one of the following: location information of the antenna reference point of the transmitting antenna, and the number of transmitting antenna reference points supported by the first node. In one possible implementation, the first information may be requested from the second node to be reported by the first node.

[0134] In some embodiments, a first node supporting self-transmitting and self-receiving sensing signals may report second information to a second node, or the second node may request the first node supporting self-transmitting and self-receiving sensing signals to report second information. The second information is used to indicate information about the associated antenna reference point pair (ARP pair) that the first node has sent to the second node.

[0135] For example, the second information includes at least one of the following:

[0136] The antenna reference point identifier for the transmitting antenna and the antenna reference point identifier for the receiving antenna;

[0137] Timestamp / time window of transmitting antenna, timestamp of receiving antenna;

[0138] Resource identifier / index (ID) for sensing signals.

[0139] In some embodiments, for a sensing node having multiple transmitting antenna reference points and multiple receiving antenna reference points, at least one of the following can be supported:

[0140] The sensing receiving node can report or be requested to report the results of antenna reference point measurements based on one or more receiving antennas to the sensing core network / base station / terminal;

[0141] The sensing transmitting node reports or is requested to report information about the sensing signals it has transmitted to the sensing core network / base station / terminal. The information about the transmitted sensing signals includes at least one of the following: the identifier of the antenna reference point of the transmitting antenna, the identifier of the antenna reference point of the receiving antenna, the timestamp, the time window, the sensing signal transmission configuration index, and the transmission port index.

[0142] The following is an exemplary description of the communication method provided in the embodiments of this disclosure:

[0143] Assume the first node is the sensing transmitting node, the second node is the sensing core network / base station, and the third node is the sensing receiving node. For example... Figure 4 The diagram shown is a flowchart of another communication method provided in an embodiment of this disclosure, used to indicate the process of capability interaction, sensing signal configuration interaction, and sensing signal measurement result interaction.

[0144] The ability to interact with single-port / multi-port sensing signals includes:

[0145] The sensing transmitting node transmits its single-port / multi-port sensing signal transmission capability to the sensing core network / base station; the sensing receiving node transmits its single-port / multi-port sensing signal measurement capability to the sensing core network / base station.

[0146] The sensor signal configuration interaction includes:

[0147] The sensing sending node requests the sensing core network / base station to configure single-port / multi-port sensing signals.

[0148] The sensing transmitting node receives sensing signals from the sensing core network / base station for configuration.

[0149] In one possible implementation, the sensing core network requests the base station to configure single-port / multi-port sensing signal configuration;

[0150] In one possible implementation, the sensing core network requests the sensing transmitting node to send a single-port / multi-port sensing signal configuration.

[0151] In one possible implementation, when the sensing transmitting node is a base station, it may not receive sensing signal configuration from the sensing core network / base station. In this case, the sensing transmitting node can configure the sensing signal configuration according to a request or sensing requirements. The sensing transmitting node can configure the sensing signal parameters to the sensing core network or the sensing receiving node transmitter.

[0152] The interaction of sensing measurement results includes: the sensing core network / base station sending a measurement request to the sensing receiving node; and the sensing core network / base station receiving the measurement report sent by the sensing receiving node.

[0153] In some embodiments, for a two-port sensing reference signal, the two ports of the sensing transmitting node can be allowed to transmit cross-polarized sensing signals, and the sensing receiving node receives the ratio of the phase difference to the received power of the cross-polarized two-port sensing signals, which is beneficial for polarized sensing target identification.

[0154] In one possible implementation, the resources of the sensed signal can be configured using a comb-like structure combined with frequency-domain orthogonal coverage codes or time-domain orthogonal coverage codes; that is, considering comb-like configuration of frequency units or time units. For example, ... Figure 5 The diagram shown is a resource configuration schematic provided by an embodiment of this disclosure, including a resource graph with a comb size of 2 and no orthogonal overlay code; a resource graph with a comb size of 2 and a time-domain resource unit of 2 symbols; and a resource graph with a comb size of 2 and a frequency-domain resource unit of 2 resource elements (REs).

[0155] In another possible implementation, different polarization ports can be used to correspond to different comb offsets to configure the resources for sensing signals.

[0156] In some embodiments, sensing and communication can be combined. For example, during the sensing phase, multi-port sensing signals can be emitted, covering multiple directions, to collect environmental reflection signals. During the communication phase, the sensing results can be used to optimize the beam and transmit user data (e.g., by selecting a codebook based on the results measured by the sensing signals). At the feedback node, the terminal can report sensing auxiliary information (such as target position and velocity) to optimize the subsequent sensing signal port configuration.

[0157] The communication method provided in this disclosure can be applied to... Figure 1 The third node 103 in the communication system shown. Figure 6 A flowchart illustrating another communication method is shown, such as... Figure 6 As shown, the communication method includes the following S601-S602:

[0158] S601, Receive the reflected signal from the object being sensed.

[0159] Among them, the reflected signal is the sensing signal sent by the first node reflected by the sensing object.

[0160] S602, Send the sensing measurement results to the second node.

[0161] The sensing measurement result is the measurement result of the reflected signal of the sensing object.

[0162] In some embodiments, the sensing measurement results include at least one of the following: the port index of the first node transmitting sensing signals, the number of ports of the first node transmitting sensing signals, the sensing measurement results corresponding to each of the multiple transmitting ports of the first node, the sensing measurement results corresponding to the transmitting port of the associated first node and the receiving port of the second node, and the sensing measurement results corresponding to the transmitting port of the associated first node and the receiving antenna polarization direction of the second node.

[0163] In some embodiments, the method further includes: receiving sensing measurement request information from a second node. At this time, S602, sending sensing measurement results to the second node includes: sending sensing measurement results to the second node based on the sensing measurement request information.

[0164] In some embodiments, the sensing measurement request information includes at least one of the following: requesting to report sensing measurement results from one or more transmitting ports of a first node; requesting to measure sensing signals based on one or more receiving ports of a third node; requesting to report differential sensing measurement results; a reference transmitting port for determining differential results; a reference receiving port for determining differential results; a reference receiving polarization direction for determining differential results; requesting to report sensing measurement results corresponding to the transmitting port (or transmitting resource) of the associated first node and the receiving port of the second node; and requesting to report sensing measurement results corresponding to the transmitting port (or transmitting resource) of the associated first node and the receiving antenna polarization direction of the second node.

[0165] Specifically, the request may involve reporting sensing measurement results from one or more transmission ports of the first node. Specifically, the second node may request the third node to report only the sensing measurement results from the transmission ports requested by the second node. Alternatively, the second node may request the third node to report the sensing measurement results corresponding to the sensing signal configuration requested by the second node. For example, the sensing measurement request message may include the number of sensing signal configurations, the number of transmission ports, and the index of the sensing signal configuration or the index of the sensing signal's transmission port, so that the third node reports the sensing measurement results corresponding to the sensing signal configuration index or the sensing signal transmission port index.

[0166] The request is made to measure the sensed signal based on one or more receiving ports of the third node. Specifically, the second node can request the third node to report the measurement and sensing results corresponding to the receiving ports requested by the second node. For example, the sensed measurement request message may include the number of receiving ports or the index of the receiving ports.

[0167] The reference transmitting port, the reference receiving port, or the reference receiving polarization direction used to determine the differential result can be used by the second node to determine the differential sensing measurement result.

[0168] For example, a request to report the sensing measurement results corresponding to the sending port (or sending resource) of the associated first node and the receiving port of the second node can be in the form of {sending port / sending resource #n, receiving port #m}. Here, #n represents the index or sequence number of the sending port / sending resource, and #m represents the index or sequence number of the receiving port.

[0169] The request to report the sensing measurement results corresponding to the polarization direction of the transmitting port of the associated first node and the receiving antenna of the second node can be in the form of {transmitting port / transmitting signal resource #n, receiving antenna polarization direction #m}. Here, #n represents the index or sequence number of the transmitting port / transmitting resource, and #m represents the index or sequence number of the receiving antenna polarization direction. In one possible implementation, the receiving antenna polarization direction can be one or more of horizontal polarization, vertical polarization, 45-degree polarization, and -45-degree polarization.

[0170] In some embodiments, the second node can dynamically activate, deactivate, or adjust the port configuration of the sensing signal based on the feedback sensing results. For example, after receiving a measurement report from the third node, the second node can adjust the sensing signal transmission port configuration.

[0171] In some embodiments, receiving the reflected signal from the sensed object includes: receiving the reflected signal from the sensed object based on a quasi-co-location (QCL) reference source of the sensed signal. It should be noted that quasi-co-location refers to multiple signals / channels having statistical correlation on specific parameters, or in other words, the relevant parameters of the channel environment of multiple signals / channels are similar or consistent on a large scale. In this case, the receiver can determine the characteristics or parameters of other signals among the multiple signals based on a known quasi-co-location reference source. That is, the third node can reliably receive the reflected signal based on the quasi-co-location reference source of the sensed signal without having to remeasure.

[0172] In some embodiments, the quasi-co-located reference source corresponds to a positioning reference signal and / or a communication signal other than a sensing signal. Exemplarily, the quasi-co-located reference source includes at least one of the following: a synchronization signal block (SSB), a channel state information reference signal (CSI-RS) for channel state information, a channel state information reference signal (CSI-RS) for beam management, a channel state information reference signal (CSI-RS) for tracking reference signal, a channel state information reference signal (CSI-RS) for radio link monitoring, a channel state information reference signal (CSI-RS) for radio resource management, a demodulation reference signal (DM-RS), a phase-tracking reference signal (PT-RS), and a sounding reference signal (SRS).

[0173] In some embodiments, the parameters of the quasi-co-located reference source (or quasi-co-located reference parameters) include at least one of the following: Doppler offset, Doppler spread, average delay, delay spread, average gain, and spatial reception parameters.

[0174] For example, assuming the quasi-co-located reference source is the positioning reference signal and the quasi-co-located reference parameters are the spatial receiving parameters, the third node receives the reflected signal based on the receiving beam of the positioning reference signal.

[0175] It should be noted that different quasi-co-located reference sources can be set for different quasi-co-located reference parameters, and there can be multiple quasi-co-located reference sources. For example, for the spatial reception parameter (QCL-type D), the reference source can be DL-PRS, SRS, SL-PRS, SSB, or CSI-RS for RRM.

[0176] In some embodiments, the method further includes:

[0177] Report the capability information of the third node to the second node;

[0178] The capability information of the third node includes at least one of the following:

[0179] Does it support reporting the measurement results of sensing signals from multiple transmission ports?

[0180] Supports reporting the maximum number of sensing signal measurement results from multiple transmission ports;

[0181] Does it support measuring sensed signals based on multiple receiving ports?

[0182] The maximum number of receiving ports that can support the measurement and sensing of signals based on multiple receiving ports;

[0183] Does it support measuring sensing signals based on multiple receiving polarization directions?

[0184] Supports measuring the number of maximum receiving polarization directions in a sensed signal based on multiple receiving polarization directions;

[0185] Supports measuring the supported receiver polarization types in the sensed signal based on multiple receiver polarization directions;

[0186] Does it support reporting the sensing measurement results corresponding to the associated sending port (or sending resource) and receiving port?

[0187] The maximum number of sensing measurement results corresponding to the associated sending port (or sending resource) and receiving port that can be reported is supported;

[0188] Does it support reporting the sensing measurement results of the associated transmitting port (or transmitting resource) and the polarization direction of the receiving antenna?

[0189] The maximum number of sensing measurement results that can be reported for the associated transmitting port (or transmitting resource) and receiving antenna polarization direction is supported.

[0190] In one possible implementation, the associated transmit port (or transmit resource) and receive port can be in the form of {transmit port / transmit signal resource #n, receive port #m}. The associated transmit port (or transmit resource) and receive antenna polarization direction can also be in the form of {transmit port / transmit signal resource #n, receive antenna polarization direction #m}.

[0191] In some embodiments, the first node and the second node may be the same node or different nodes.
