Description

Technical Field

[0001] The present application relates generally to sensing in wireless networks and, in particular embodiments, to communication-assisted sensing. Background Art

[0002] Existing sensing schemes can be considered to have the characteristics of single-base sensing or multi-base sensing.

[0003] In a single-base sensing scheme, a given network node transmits a radio frequency (RF) sensing signal. The given network node also receives an echo of the RF sensing signal. This configuration is convenient in that no additional overhead known to be associated with the use of pilot signals is required, since the communication data can be reused for the sensing signal. However, it may be considered that the single-base sensing scheme relies on full-duplex capability or special signal design for sensing reception. In addition, it may be considered that the range of sensing is limited to the area around a given network node.

[0004] In multistatic sensing, the node that receives the echo of the sensing signal is different from the node that sent the sensing signal. An example of multistatic sensing is bistatic sensing, where a sending node sends the sensing signal and a receiving node receives the sensing signal after it passes through a channel between the sending node and the receiving node. The use of multistatic sensing can achieve efficient and scalable environmental sensing through cooperative sensing. Summary of the invention

[0005] There are many challenges in exploiting the advantages of multi-base sensing for future wireless communication networks. In multi-base sensing approaches based on the use of dedicated sensing pilot signals, the disadvantage is the amount of overhead caused by the dedicated sensing pilot signals. Alternatively, in approaches based on reusing communication pilot signals as sensing pilot signals, the communication pilots may be considered too sparse to achieve processing gain that provides adequate sensing performance.

[0006] Various aspects of the present application relate to a solution that implements a multi-base sensing solution in a manner that aims to avoid the above-mentioned disadvantages of the existing proposed solutions.

[0007] Various aspects of the present application relate to using communication data as perception pilot signals. One advantage of using communication data as perception pilot signals is that perception overhead is reduced. Another advantage of using communication data as perception pilot signals is that there is processing gain. The processing gain can be attributed to a large number of data symbols. A large number of data symbols can be displayed to achieve relatively simple fast Fourier transform (FFT)-based reception. Another advantage of using communication data as perception pilot signals is that the communication data can be viewed as similar to a large-sized random data set. Using a large-sized random data set to perceive pilot signals may prove to have advantages in terms of automatic ambiguity. It is known that automatic ambiguity is a key performance indicator in terms of delay estimation and Doppler frequency offset estimation.

[0008] Various aspects of the present application relate to various communication-assisted sensing schemes, in which user equipment can use communication signals for sensing purposes.

[0009] After learning the sensing capabilities of the device, the network node may send a sensing report configuration to the device. The network node may send a definition of a sensing area of ​​a communication scheduling area to the device. The network node may also send a definition of a sensing feedback reporting channel to the device. After sending the scheduled data transmission to the device, the network node may receive a sensing report from the device on the sensing feedback reporting channel based on processing the scheduled data transmission received by the device in the sensing area.

[0010] Existing versions of multi-base awareness solutions do not provide an end-to-end solution to address the overhead and performance issues inherent in existing versions of multi-base awareness solutions.

[0011] Various aspects of the present application relate to a multi-base sensing solution, the solution being characterized in that the sensing performance can be optimized according to the sensing capabilities of the nodes expected to perform the sensing. Efficient sensing can be achieved by processing the scheduled data transmission to obtain the sensing parameters. Since the use of additional sensing overhead is avoided, the sensing can be considered to be efficient. There are a large number of data symbols in the scheduled data transmission, so the sensing performance enhancement (partly due to the increase in processing gain) and the resolution enhancement can be considered possible. It can be seen that the large number of data symbols can realize a very simple sensing reception algorithm (e.g., an FFT-based scheme) without the need for complex algorithms (e.g., super-resolution schemes).

[0012] Various aspects of the present application relate to a configuration for efficient sensory feedback reporting. That is, sensory feedback reporting can be more efficient by associating multiple data blocks.

[0013] Various aspects of the present application relate to decoding and processing scheduled data transmissions on multiple beams for sensing purposes. Advantageously, power savings can be achieved because the beamforming is known during communication setup and power does not need to be expended on beamforming of sensing signals.

[0014] According to an aspect of the present invention, a method for a network node or base station is provided. The method comprises receiving a sensing capability report from a device. The method further comprises sending a definition of a sensing area to the device, the sensing area definition being defined based on the sensing capability report. The method further comprises sending a definition of a sensing feedback reporting channel to the device, and sending a data transmission to the device. The method further comprises receiving a sensing report from the device on the sensing feedback reporting channel based on processing a scheduled data transmission received in the sensing area.

[0015] According to another aspect of the present invention, a method for an electronic device or user equipment is provided. The method includes sending a perception capability report to a base station. The method also includes receiving a definition of a perception area from the base station, the perception area definition being defined based on the perception capability report. The method also includes receiving a definition of a perception feedback reporting channel from the base station, and the base station receiving a data transmission. The method also includes sending a perception report to the base station on the perception feedback reporting channel based on processing the data transmission received in the perception area.

[0016] Further aspects of the present invention relate to an apparatus, a computer-readable storage medium, a computer program product and a processor for performing the aforementioned method.

[0017] According to another aspect of the present invention, a system is provided, comprising a device and a base station in wireless communication with the device. The device is configured to send a sensing capability report and receive a data transmission. The device is further configured to send a sensing report on a sensing feedback reporting channel based on processing the data transmission received in a sensing area. The base station is configured to send a definition of the sensing area based on the sensing capability report to the device. The base station is further configured to send a definition of the sensing feedback reporting channel based on the sensing capability report to the device. The base station is further configured to send the data transmission to the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] refer to Figure 1 , a simplified schematic diagram of a communication system is provided as a non-limiting illustrative example. The communication system 100 includes a radio access network 120. The radio access network 120 may be a next generation (e.g., sixth generation (6G) or higher) radio access network or a traditional (e.g., 5G, 4G, 3G or 2G) radio access network. One or more communication electronic devices (electric devices, ED) 110a, 110b, 110c, 110d, 110e, 110f, 110g, 110h, 110i, 110j (generally referred to as 110) may be interconnected or connected to one or more network nodes (170a, 170b, generally referred to as 170) in the radio access network 120. The core network 130 may be part of the communication system and may be dependent on or independent of the radio access technology used in the communication system 100. In addition, the communication system 100 includes a public switched telephone network (PSTN) 140, the Internet 150, and other networks 160.

[0040] Figure 2An exemplary communication system 100 is shown. Typically, the communication system 100 enables multiple wireless or wired elements to transmit data and other content. The communication system 100 can be used to provide content such as voice, data, video and / or text through broadcast, multicast and unicast, etc. The communication system 100 can operate by sharing resources such as carrier spectrum bandwidth between its constituent elements. The communication system 100 may include a terrestrial communication system and / or a non-terrestrial communication system. The communication system 100 can provide a wide range of communication services and applications (such as earth monitoring, remote sensing, passive perception and positioning, navigation and tracking, autonomous delivery and mobility, etc.). The communication system 100 can provide a high degree of availability and robustness through the joint operation of the terrestrial communication system and the non-terrestrial communication system. For example, integrating a non-terrestrial communication system (or its components) into a terrestrial communication system can produce a heterogeneous network that can be regarded as consisting of multiple layers. Compared with traditional communication networks, heterogeneous networks can obtain better overall performance through efficient multi-link joint operation between terrestrial networks and non-terrestrial networks, more flexible function sharing, and faster physical layer link switching.

[0041] Terrestrial communication systems and non-terrestrial communication systems can be considered as subsystems of the communication system. Figure 2 In the example shown, the communication system 100 includes electronic devices (EDs) 110a, 110b, 110c, 110d (generally referred to as EDs 110), radio access networks (RANs) 120a, 120b, non-terrestrial communication networks 120c, core networks 130, public switched telephone networks (PSTNs) 140, the Internet 150, and other networks 160. The RANs 120a, 120b include corresponding base stations (BSs) 170a, 170b, which may be generally referred to as terrestrial transmit and receive points (T-TRPs) 170a, 170b. The non-terrestrial communication network 120c includes an access node 172, which may be generally referred to as a non-terrestrial transmit and receive point (NT-TRP) 172.

[0042] Alternatively or additionally, any ED 110 may be used to connect, access, or communicate with any T-TRP 170a, T-TRP 170b, and NT-TRP 172, the Internet 150, the core network 130, the PSTN 140, other networks 160, or any combination of the foregoing. In some examples, ED 110a may communicate with T-TRP 170a for uplink and / or downlink transmissions via a ground air interface 190a. In some examples, ED 110a, 110b, 110c, and 110d may also communicate directly with each other via one or more sidelink air interfaces 190b. In some examples, ED 110d may communicate with NT-TRP 172 for uplink and / or downlink transmissions via a non-ground air interface 190c.

[0043] The air interfaces 190a and 190b may use similar communication technologies, such as any applicable wireless access technology. For example, the communication system 100 may implement one or more channel access methods in the air interfaces 190a and 190b, such as code division multiple access (CDMA), space division multiple access (SDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal FDMA (OFDMA), single-carrier FDMA (SC-FDMA) or direct Fourier transform spread OFDMA (DFT-OFDMA). The air interfaces 190a and 190b may utilize other high-dimensional signal spaces, which may involve a combination of orthogonal dimensions and / or non-orthogonal dimensions.

[0044] The non-terrestrial air interface 190c can enable communication between ED 110d and one or more NT-TRPs 172 via a wireless link or a simple link. For some examples, the link is a dedicated connection for unicast transmission, a connection for broadcast transmission, or a connection between a group of EDs 110 and one or more NT-TRPs 175 for multicast transmission.

[0045] The RANs 120a and 120b communicate with the core network 130 to provide voice, data, and other services to the EDs 110a, 110b, and 110c. The RANs 120a and 120b and / or the core network 130 may communicate directly or indirectly with one or more other RANs (not shown), which may (or may not) be directly served by the core network 130 and may (or may not) use the same radio access technology as the RANs 120a and / or RANs 120b. The core network 130 may also serve as a gateway access between (i) the RANs 120a and 120b and / or the EDs 110a, 110b, and 110c and (ii) other networks, such as the PSTN 140, the Internet 150, and other networks 160. In addition, some or all of the EDs 110a, 110b, and 110c may include functionality to communicate with different wireless networks over different radio links using different radio technologies and / or protocols. Instead of (or in addition to) wireless communications, EDs 110a, 110b, and 110c may communicate with a service provider or switch (not shown) and with the Internet 150 via a wired communication channel. PSTN 140 may include a circuit-switched telephone network for providing plain old telephone service (POTS). Internet 150 may include a network of computers and / or subnets (intranets) and may include protocols such as Internet Protocol (IP), Transmission Control Protocol (TCP), and User Datagram Protocol (UDP). EDs 110a, 110b, and 110c may be multi-mode devices capable of operating in accordance with a variety of wireless access technologies and may include multiple transceivers required to support these technologies.

Each ED 110 connected to T-TRP 170 and / or NT-TRP 172 can be dynamically or semi-statically opened (i.e., established, activated or enabled), closed (i.e., released, deactivated or disabled) and / or configured in response to one or more of connection availability and connection necessity.

[0048] ED 110 includes a transmitter 201 and a receiver 203 coupled to one or more antennas 204. Only one antenna 204 is shown. Alternatively, one, some or all of the antennas 204 may be panels. Transmitter 201 and receiver 203 may be integrated into a transceiver, for example. The transceiver is used to modulate data or other content so that it can be sent through at least one antenna 204 or a network interface controller (NIC). The transceiver can also be used to demodulate data or other content received through at least one antenna 204. Each transceiver includes any applicable structure for generating signals for wireless or wired transmission and / or for processing signals received wirelessly or wired. Each antenna 204 includes any applicable structure for sending and / or receiving wireless or wired signals.

[0049] ED 110 includes at least one memory 208. Memory 208 stores instructions and data used, generated, or collected by ED 110. For example, memory 208 may store software instructions or modules for implementing some or all of the functions and / or embodiments described herein and executed by one or more processing units (e.g., processor 210). Each memory 208 includes any applicable volatile and / or non-volatile storage and retrieval device.

Each input / output device includes any suitable structure for providing information to or receiving information from a user, such as through the operation of a speaker, microphone, keypad, keyboard, display, or touch screen (including network interface communication).

[0051] ED 110 includes a processor 210 for performing operations including operations related to preparing transmissions for uplink transmission to NT-TRP 172 and / or T-TRP 170, operations related to processing downlink transmissions received from NT-TRP 172 and / or T-TRP 170, and operations related to processing sidelink transmissions to and from another ED 110. Processing operations related to preparing transmissions for uplink transmissions may include operations such as encoding, modulation, transmit beamforming, and generating symbols for transmission. Processing operations related to processing downlink transmissions may include operations such as receive beamforming, demodulation, and decoding received symbols. According to an embodiment, receiver 203 may receive downlink transmissions, possibly using receive beamforming, and processor 210 may extract signaling from the downlink transmissions (e.g., by detecting and / or decoding the signaling). An example of signaling may be a reference signal sent by NT-TRP 172 and / or T-TRP 170. In some embodiments, the processor 210 implements transmit beamforming and / or receive beamforming according to a beam direction indication, such as beam angle information (BAI), received from the T-TRP 170. In some embodiments, the processor 210 may perform operations related to network access (e.g., initial access) and / or downlink synchronization, such as operations related to detecting a synchronization sequence, decoding, and obtaining system information. In some embodiments, the processor 210 may perform channel estimation, for example, using a reference signal received from the NT-TRP 172 and / or the T-TRP 170.

[0052] Although not shown, the processor 210 may constitute a part of the transmitter 201 and / or a part of the receiver 203. Although not shown, the memory 208 may constitute a part of the processor 210.

[0053] The processor 210, the processing components of the transmitter 201, and the processing components of the receiver 203 may all be implemented by the same or different one or more processors for executing instructions stored in a memory (e.g., the memory 208). Alternatively, some or all of the processor 210, the processing components of the transmitter 201, and the processing components of the receiver 203 may be implemented using a programmed field-programmable gate array (FPGA), a central processing unit (CPU), a graphical processing unit (GPU), or a dedicated circuit such as an application-specific integrated circuit (ASIC).

T-TRP 170 may refer to the above-mentioned device or a means in the above-mentioned device (eg, a communication module, a modem, or a chip).

[0055] In some embodiments, various parts of T-TRP 170 may be distributed. For example, some modules of T-TRP 170 may be located at the far end of the device that houses the antenna 256 of T-TRP 170, and may be coupled to the device that houses the antenna 256 through a communication link (not shown) sometimes called a fronthaul, such as a common public radio interface (CPRI). Therefore, in some embodiments, the term T-TRP 170 may also refer to the modules on the network side that perform processing operations such as ED 110 location determination, resource allocation (scheduling), message generation, and encoding / decoding, which are not necessarily part of the device that houses the antenna 256 of T-TRP 170. These modules may also be coupled to other T-TRPs. In some embodiments, T-TRP 170 may actually be multiple T-TRPs that operate together to serve ED 110, for example, by using coordinated multi-point transmission.

[0056] like Figure 3As shown, T-TRP 170 includes at least one transmitter 252 and at least one receiver 254 coupled to one or more antennas 256. Only one antenna 256 is shown. Alternatively, one, some, or all of antennas 256 may be panels. Transmitter 252 and receiver 254 may be integrated as a transceiver. T-TRP 170 also includes a processor 260 for performing operations, including operations related to: preparing transmissions for downlink transmission to ED 110; processing uplink transmissions received from ED 110; preparing transmissions for backhaul transmission to NT-TRP 172; and processing transmissions received from NT-TRP 172 in the backhaul. Processing operations related to preparing transmissions for downlink or backhaul transmissions may include operations such as coding, modulation, precoding (e.g., multiple input multiple output (MIMO) precoding), transmit beamforming, and generating symbols for transmission. Processing operations associated with processing transmissions received in the uplink or backhaul may include operations such as receive beamforming, demodulating received symbols, and decoding received symbols. Processor 260 may also perform operations associated with network access (e.g., initial access) and / or downlink synchronization, such as generating the content of a synchronization signal block (SSB), generating system information, etc. In some embodiments, processor 260 also generates a beam direction indication, such as a BAI, which scheduler 253 may schedule for transmission. Processor 260 performs other network-side processing operations described herein, such as determining the location of ED 110, determining the deployment location of NT-TRP 172, etc. In some embodiments, processor 260 may generate signaling, such as to configure one or more parameters of ED 110 and / or one or more parameters of NT-TRP 172. Any signaling generated by processor 260 is sent by transmitter 252. It should be noted that "signaling" used herein may also be referred to as control signaling. Dynamic signaling may be sent in a control channel such as a physical downlink control channel (PDCCH), and static or semi-static high-layer signaling may be included in a data packet sent in a data channel such as a physical downlink shared channel (PDSCH).

[0057] The scheduler 253 may be coupled to the processor 260. The scheduler 253 may be included in the T-TRP 170 or may operate separately.

The T-TRP 170 also includes a memory 258 for storing information and data. The memory 258 stores instructions and data used, generated, or collected by the T-TRP 170. For example, the memory 258 may store software instructions or modules for implementing some or all of the functions and / or embodiments described herein and executed by the processor 260.

[0058] Although not shown, the processor 260 may constitute a part of the transmitter 252 and / or a part of the receiver 254. In addition, although not shown, the processor 260 may implement the scheduler 253. Although not shown, the memory 258 may constitute a part of the processor 260.

[0059] The processor 260, the scheduler 253, the processing components of the transmitter 252, and the processing components of the receiver 254 may all be implemented by the same or different processors in one or more processors for executing instructions stored in a memory (e.g., the memory 258). Alternatively, some or all of the processor 260, the scheduler 253, the processing components of the transmitter 252, and the processing components of the receiver 254 may be implemented using a dedicated circuit such as an FPGA, a CPU, a GPU, or an ASIC.

[0060] It should be noted that the NT-TRP 172 is shown as a drone only as an example, and the NT-TRP 172 can be implemented in any applicable non-ground form, such as a high-altitude platform, a satellite, a high-altitude platform as an international mobile telecommunication base station, and an unmanned aerial vehicle, which will be discussed below. In addition, in some implementations, the NT-TRP 172 may have other names, such as a non-ground node, a non-ground network device, or a non-ground base station. The NT-TRP 172 includes a transmitter 272 and a receiver 274 coupled to one or more antennas 280. Only one antenna 280 is shown. Alternatively, one, some or all of the antennas can be panels. The transmitter 272 and the receiver 274 can be integrated into a transceiver. NT-TRP 172 also includes a processor 276 for performing operations, including operations related to: preparing transmissions for downlink transmission to ED 110; processing uplink transmissions received from ED 110; preparing transmissions for backhaul transmission to T-TRP 170; and processing transmissions received from T-TRP 170 in the backhaul. Processing operations related to preparing transmissions for downlink or backhaul transmissions may include operations such as encoding, modulation, precoding (e.g., MIMO precoding), transmit beamforming, and generating symbols for transmission. Processing operations related to processing transmissions received in the uplink or backhaul may include operations such as receive beamforming, demodulating received signals, and decoding received symbols. In some embodiments, processor 276 implements transmit beamforming and / or receive beamforming based on beam direction information (e.g., BAI) received from T-TRP 170. In some embodiments, processor 276 may generate signaling, such as to configure one or more parameters of ED 110. In some embodiments, NT-TRP 172 implements physical layer processing but does not implement higher layer functions such as functions of the medium access control (MAC) or radio link control (RLC) layer. This is only an example, and more generally, NT-TRP 172 may implement higher layer functions in addition to physical layer processing.

[0061] The NT-TRP 172 also includes a memory 278 for storing information and data. Although not shown, the processor 276 may constitute a part of the transmitter 272 and / or a part of the receiver 274. Although not shown, the memory 278 may constitute a part of the processor 276.

[0062] Processor 276, the processing components of transmitter 272, and the processing components of receiver 274 may all be implemented by the same or different one or more processors for executing instructions stored in a memory (e.g., memory 278). Alternatively, some or all of processor 276, the processing components of transmitter 272, and the processing components of receiver 274 may be implemented using a programmed FPGA, CPU, GPU, or ASIC, etc., for dedicated circuits. In some embodiments, NT-TRP 172 may actually be multiple NT-TRPs operating together to serve ED 110, for example, via coordinated multi-point transmission.

[0063] The T-TRP 170, NT-TRP 172, and / or ED 110 may include other components, but these components have been omitted for clarity.

[0064] One or more steps of the exemplary methods provided herein may be performed by Figure 4 The corresponding unit or module is executed. Figure 4 Units or modules in devices such as ED 110, T-TRP 170, or NT-TRP 172 are shown. For example, a signal can be sent by a sending unit or a sending module. A signal can be received by a receiving unit or a receiving module. A signal can be processed by a processing unit or a processing module. Other steps can be performed by an artificial intelligence (AI) module or a machine learning (ML) module. The corresponding units or modules can be implemented using hardware, one or more components or devices that execute software, or a combination thereof. For example, one or more units or modules can be programmed integrated circuits such as FPGAs, CPUs, GPUs, or ASICs. It should be understood that if these modules are implemented, for example, using software executed by a processor, these modules can be retrieved by the processor in whole or in part as needed, retrieved individually or collectively for processing, retrieved in one or more instances, and these modules themselves can include instructions for further deployment and instantiation.

[0065] Other details about ED 110, T-TRP 170 and NT-TRP 172 are known to those skilled in the art. Therefore, these details are omitted here.

[0066] Devices such as base station 170 can cover a cell. Wireless communication with a device can occur on one or more carrier frequencies. A carrier frequency will be referred to as a carrier. Alternatively, a carrier may be referred to as a component carrier (CC). A carrier can be characterized by its bandwidth and reference frequency, such as the center frequency, the lowest frequency, or the highest frequency of the carrier. A carrier can be on a licensed spectrum or on an unlicensed spectrum. Wireless communication with a device may also or conversely occur on one or more bandwidth parts (BWPs). For example, a carrier may have one or more BWPs. More generally, wireless communication with a device may occur on a spectrum. A spectrum may include one or more carriers and / or one or more BWPs.

[0067] The cell may include one or more downlink resources, optionally one or more uplink resources. The cell may include one or more uplink resources, optionally one or more downlink resources. The cell may include both one or more downlink resources and one or more uplink resources. As an example, the cell may include only one downlink carrier / BWP, or only one uplink carrier / BWP, or multiple downlink carriers / BWP, or multiple uplink carriers / BWP, or one downlink carrier / BWP and one uplink carrier / BWP, or one downlink carrier / BWP and multiple uplink carriers / BWP, or multiple downlink carriers / BWP and one uplink carrier / BWP, or multiple downlink carriers / BWP and multiple uplink carriers / BWP. In some embodiments, alternatively or additionally, the cell may include one or more sidelink resources, including sidelink transmission and reception resources.

[0068] A BWP is a set of continuous or non-contiguous frequency subcarriers on one carrier, or a set of continuous or non-contiguous frequency subcarriers on multiple carriers, or a set of non-contiguous or continuous frequency subcarriers, and may have one or more carriers.

[0069] In some embodiments, a carrier may have one or more BWPs, for example, a carrier may have a bandwidth of 20 MHz and consist of one BWP, or a carrier may have a bandwidth of 80 MHz and consist of two adjacent continuous BWPs, etc. In other embodiments, a BWP may have one or more carriers, for example, a BWP may have a bandwidth of 40 MHz and consist of two adjacent continuous carriers, each of which has a bandwidth of 20 MHz. In some embodiments, a BWP may include non-continuous spectrum resources, consisting of a plurality of non-continuous multi-carriers, wherein the first carrier in the non-continuous multi-carrier may be in the mmW band, the second carrier may be in the low frequency band (e.g., the 2 GHz band), the third carrier (if present) may be in the THz band, and the fourth carrier (if present) may be in the visible light band. The resources belonging to a BWP in a carrier may be continuous or non-continuous. In some embodiments, a BWP has non-continuous spectrum resources on a carrier.

[0070] Wireless communication can occur over an occupied bandwidth. The occupied bandwidth can be defined as the width of the frequency band such that below a lower frequency limit and above an upper frequency limit, the average power transmitted is equal to a specified percentage β / 2 of the total average transmit power, for example, β / 2 is 0.5%.

[0071] The carrier, BWP or occupied bandwidth may be signaled by a network device (e.g., base station 170) dynamically (e.g., in known physical layer control signaling such as downlink control channel information (DCI)), semi-statically (e.g., in radio resource control (RRC) signaling or in signaling in the medium access control (MAC) layer), or predefined according to an application scenario, or determined by UE 110 based on other parameters known to UE 110, or may be fixed, for example, by a standard.

[0072] UE location information is often used in cellular communication networks to improve various performance indicators of the network. For example, these performance indicators may include capacity, flexibility and efficiency. Such improvements can be achieved when network elements utilize the location, behavior, mobility patterns, etc. of the UE in the context of prior information that describes the wireless environment in which the UE operates.

[0073] The perception system can be used to help collect UE posture information, including the position of the UE in the global coordinate system, the speed and direction of movement of the UE in the global coordinate system, azimuth information, and information about the wireless environment. "Location" is also called "position", and these two terms can be used interchangeably in this article. Examples of well-known perception systems include radio detection and ranging (RADAR) and light detection and ranging (LIDAR). Although the perception system is usually separated from the communication system, using an integrated system to collect information helps to reduce the hardware (and cost) in the system and the time resources, frequency resources, or space resources required to perform these two functions. However, using communication system hardware to perform perception of UE posture and environmental information is extremely challenging and is an unresolved problem. The difficulty of this problem is related to factors such as the limited resolution of the communication system, the dynamic nature of the environment, and the huge number of objects whose electromagnetic properties and positions need to be estimated.

[0074] Therefore, integrated sensing and communication (also called integrated communication and sensing) is a desirable function for existing and future communication systems.

[0075] Any or all of ED 110 and BS 170 may be perception nodes in system 100. A perception node is a network entity that performs perception by sending and receiving perception signals. Some perception nodes are communication devices that perform both communication and perception. However, it is possible that some perception nodes do not perform communication but are dedicated to perception. Perception agent 174 is an example of a perception node dedicated to perception. Unlike ED 110 and BS 170, perception agent 174 does not send or receive communication signals. However, perception agent 174 can transmit configuration information, perception information, signaling information, or other information within the communication system 100. Perception agent 174 can communicate with core network 130 to transmit information with the rest of the communication system 100. As an example, perception agent 174 can determine the location of ED 110a and send the information to base station 170a through core network 130. Although Figure 2 Only one awareness agent 174 is shown in the figure, and any number of awareness agents may be implemented in the communication system 100. In some embodiments, one or more awareness agents may be implemented at one or more RANs 120.

[0076] The sensing node can combine the sensing-based technology with the reference signal-based technology to enhance the UE posture determination. This type of sensing node may also be referred to as a sensing management function (SMF). In some networks, SMF may also be referred to as a location management function (LMF). SMF may be implemented as a physically independent entity located at a core network 130, which is connected to a plurality of BSs 170. In other aspects of the present application, SMF may be implemented as a logical entity co-located within BS 170 by logic executed by processor 260.

[0077] like Figure 5 As shown, when the SMF 176 is implemented as a physically independent entity, it includes at least one processor 290, at least one transmitter 282, at least one receiver 284, one or more antennas 286 and at least one memory 288. A transceiver (not shown) can be used instead of the transmitter 282 and the receiver 284. The scheduler 283 can be coupled to the processor 290. The scheduler 283 can be included in the SMF 176 or can be run separately. The processor 290 implements various processing operations of the SMF 176, such as signal encoding, data processing, power control, input / output processing or any other function. The processor 290 can also be used to implement some or all of the functions and / or embodiments described in more detail herein. Each processor 290 includes any applicable processing or computing device for performing one or more operations. Each processor 290 can include, for example, a microprocessor, a microcontroller, a digital signal processor, a field programmable gate array or an application-specific integrated circuit.

[0078] Reference signal based pose determination techniques belong to the "active" pose estimation paradigm. In the active pose estimation paradigm, the inquirer of pose information (e.g., UE 110) participates in the process of determining the pose of the inquirer. The inquirer can send or receive (or send and receive) signals specific to the pose determination process. Positioning techniques based on global navigation satellite systems (GNSS) such as the known global positioning system (GPS) are other examples of the active pose estimation paradigm.

[0079] In contrast, perception techniques such as radar-based ones can be considered to belong to the “passive” pose determination paradigm, where the target has no knowledge of the pose determination process.

[0080] By integrating perception and communication in one system, the system does not need to operate according to only one paradigm. Therefore, the combination of perception-based techniques and reference signal-based techniques can lead to enhanced pose determination.

[0081] For example, enhanced pose determination can include obtaining UE channel subspace information, which is particularly useful for UE channel reconstruction at the sensing node, especially for beam-based operation and communication. The UE channel subspace is a subset of the entire algebraic space defined in the spatial domain, in which the entire channel from TP to UE is located. Therefore, the UE channel subspace defines the TP-UE channel with very high accuracy. The impact of signals sent through other subspaces on the UE channel is negligible. Understanding the UE channel subspace helps reduce the workload required for UE channel measurement and network-side channel reconstruction. Therefore, compared with traditional methods, the combination of sensing-based techniques and reference signal-based techniques can achieve UE channel reconstruction with much less overhead. Subspace information can also contribute to subspace-based sensing to reduce sensing complexity and improve sensing accuracy.

[0082] In some embodiments of integrated sensing and communication, the same radio access technology (RAT) is used for sensing and communication. This avoids the need to reuse two different RATs on one carrier spectrum, or two different RATs require two different carrier spectrums.

[0083] In an embodiment of integrating sensing and communication under one RAT, the first set of channels can be used to send sensing signals and the second set of channels can be used to send communication signals. In some embodiments, each channel in the first set of channels and each channel in the second set of channels is a logical channel, a transport channel or a physical channel.

[0084] At the physical layer, communication and perception can be performed through separate physical channels. For example, a first physical downlink shared channel PDSCH-C is defined for data communication, while a second physical downlink shared channel PDSCH-S is defined for perception. Similarly, separate physical uplink shared channels (PUSCH) PUSCH-C and PUSCH-S can be defined for uplink communication and perception.

[0085] In another example, the same PDSCH and PUSCH can also be used for both communication and sensing, where separate logical layer channels and / or transport layer channels are defined for communication and sensing. It should also be noted that the control channel and the data channel used for sensing can have the same or different channel structures (formats), occupying the same or different frequency bands or bandwidth portions.

[0086] In another example, a common physical downlink control channel (PDCCH) and a common physical uplink control channel (PUCCH) can be used to carry control information for sensing and communication. Alternatively, separate physical layer control channels can be used to carry separate control information for communication and sensing. For example, PUCCH-S and PUCCH-C can be used for uplink control for sensing and communication, respectively, and PDCCH-S and PDCCH-C can be used for downlink control for sensing and communication, respectively.

[0087] At each of the physical, transport, and logical layers, different combinations of shared and dedicated channels for sensing and communication may be used.

[0088] The term RADAR originates from the phrase "radio detection and ranging"; however, the expressions with different capitalizations (e.g., radar and radar) are equally valid and are now more common. Radar is commonly used to detect the presence and location of objects. A radar system radiates radio frequency energy and receives echoes of energy reflected from one or more targets. The system determines the position of a given target based on the echoes returned from the given target. The radiated energy can be in the form of energy pulses or continuous waves, which can be represented or defined by a specific waveform. Examples of waveforms used in radar include frequency modulated continuous wave (FMCW) and ultra-wideband (UWB) waveforms.

[0089] Radar systems can be monostatic, bistatic, or multistatic. In a monostatic radar system, the radar signal transmitter and receiver are co-located, such as integrated into the transceiver. In a bistatic radar system, the transmitter and receiver are spatially separated and the separation distance is equivalent to or greater than the expected target distance (commonly referred to as range). In a multistatic radar system, two or more radar components are spatially distinct but have a shared coverage area. Multistatic radars are also called multistation or mesh radars.

[0090] Ground-based radar applications face challenges such as multipath propagation and shadowing. Another challenge is the identifiability issue, as ground targets have similar physical properties. Integrating sensing into communication systems is likely to face the same challenges, if not more.

[0091] Communication nodes can be either half-duplex or full-duplex. Half-duplex nodes cannot use the same physical resources (time, frequency, etc.) to both transmit and receive; in contrast, full-duplex nodes can use the same physical resources to transmit and receive. Existing commercial wireless communication networks are all half-duplex. Even if full-duplex communication networks become practical in the future, it is expected that at least some nodes in the network will still be half-duplex nodes because half-duplex devices have lower complexity, cost, and power consumption. In particular, full-duplex implementations are more challenging at higher frequencies (e.g., in the millimeter wave bands) and are very challenging for small, low-cost devices (such as femtocell base stations and UEs).

[0092] The limitations of half-duplex nodes in communication networks pose further challenges to devices and systems that integrate sensing and communication into communication networks. For example, both half-duplex and full-duplex nodes can perform bistatic or multistatic sensing, but monostatic sensing generally requires the sensing node to have full-duplex capabilities. Half-duplex nodes can perform monostatic sensing under certain restrictions, such as in pulse radars with specific duty cycles and ranging capabilities.

[0093] The properties of a perceptual signal or a signal used for both perception and communication include the waveform of the signal and the frame structure of the signal. The frame structure defines the time domain boundaries of the signal. The waveform describes the shape of the signal as it changes over time and frequency. Examples of waveforms that can be used to perceive signals include ultra-wideband (UWB) pulses, frequency-modulated continuous waves (FMCW) or "chirps", orthogonal frequency-division multiplexing (OFDM), cyclic prefix (CP)-OFDM, and discrete Fourier transform spread (DFT-s)-OFDM.

[0094] In an embodiment, the sensing signal is a linear chirp signal with a bandwidth of B and a duration of T. Such a linear chirp signal is well known for use in FMCW radar systems. The linear chirp signal is generated by an initial time t chirp0 The initial frequency f chirp0 To the final time t chirp1 The final frequency f chirp1 The frequency increase definition is as follows, where the relationship between frequency (f) and time (t) can be expressed as a linear relationship ff chirp0 =α(tt chirp0 ),,in Defined as the chirp slope. The bandwidth of a linear chirp signal can be defined as B = fchirp1 -f chirp0 , the duration of the linear chirp signal can be defined as T = t chirp1 -t chirp0 In baseband representation, this linear chirp signal can be expressed as

[0095] As used herein, precoding may refer to any coding operation or modulation that transforms an input signal into an output signal. Precoding may be performed in different domains and typically transforms an input signal in a first domain into an output signal in a second domain. Precoding may include linear operations.

[0096] Terrestrial communication systems can also be referred to as land-based or on-ground communication systems, but terrestrial communication systems can also or alternatively be implemented on or in the water. Non-terrestrial communication systems can fill the coverage gaps in underserved areas by expanding the coverage of cellular networks using non-terrestrial nodes, which is essential for establishing seamless global coverage and providing mobile broadband services to unserved / underserved areas. In the current scenario, it is almost impossible to implement terrestrial access point / base station infrastructure in oceans, mountains, forests or other remote areas.

[0097] The terrestrial communication system may be a wireless communication system using 5G technology and / or next generation wireless technology (e.g., 6G or higher). In some examples, the terrestrial communication system may also adapt to some traditional wireless technologies (e.g., 3G or 4G wireless technologies). The non-terrestrial communication system may be a communication system using a satellite constellation such as a traditional geostationary orbit (GEO) satellite, which broadcasts public / hotspot content to a local server. The non-terrestrial communication system may be a communication system using a low earth orbit (LEO) satellite, and it is known that LEO satellites can better balance large coverage areas with propagation path loss / delay. The non-terrestrial communication system may be a communication system using very low earth orbit (VLEO) stable satellite technology, thereby greatly reducing the cost of launching satellites into lower orbits. The non-terrestrial communication system may be a communication system using a high altitude platform (HAP), and it is known that HAP provides a low path loss air interface for users with limited power budgets. A non-terrestrial communication system may be a communication system that uses an unmanned aerial vehicle (UAV) (or unmanned aerial system, UAS) to achieve dense deployment, because the coverage of the UAV (or UAS) may be limited to a local area, such as airborne, balloon, quadcopter, drone, etc. In some examples, GEO satellites, LEO satellites, UAVs, HAPs, and VLEOs may be horizontal and two-dimensional. In some examples, UAVs, HAPs, and VLEOs may be coupled to integrate satellite communications into cellular networks. The emerging 3D vertical network consists of many mobile (except geostationary satellites) and high-altitude access points such as UAVs, HAPs, and VLEOs.

[0098] MIMO technology enables an antenna array consisting of multiple antennas to send and receive signals to meet high transmission rate requirements. ED 110 and T-TRP 170 and / or NT-TRP can use MIMO to communicate through wireless resource blocks. MIMO uses multiple antennas at the transmitter to send wireless resource blocks through parallel wireless signals. It can be seen that multiple antennas can be used at the receiver. MIMO can beamform parallel wireless signals to achieve reliable multipath transmission of wireless resource blocks. MIMO can bind parallel wireless signals that transmit different data together to increase the data rate of the wireless resource block.

[0099] In recent years, a MIMO (massive MIMO) wireless communication system having a T-TRP 170 and / or NT-TRP 172 configured with a large number of antennas has attracted widespread attention from academia and industry. In a massive MIMO system, a T-TRP 170 and / or NT-TRP 172 is usually configured with more than ten antenna elements (see Figure 3 The T-TRP 170 and / or NT-TRP 172 are typically used to serve dozens (e.g., 40) of EDs 110. The large number of antenna units of the T-TRP 170 and NT-TRP 172 can greatly improve the spatial freedom of wireless communications, greatly improve the transmission rate, spectrum efficiency, and power efficiency, and reduce inter-cell interference to a great extent. The increase in the number of antennas allows each antenna unit to be made smaller and less expensive. By utilizing the spatial freedom provided by the large-scale antenna units, the T-TRP 170 and NT-TRP 172 of each cell can communicate with multiple EDs 110 in the cell simultaneously on the same time-frequency resources, thereby greatly improving the spectrum efficiency. The large number of antenna units of the T-TRP 170 and / or NT-TRP 172 also enables each user to have better spatial directivity during uplink and downlink transmissions, thereby reducing the transmit power of the T-TRP 170 and / or NT-TRP 172 and ED 110, and correspondingly improving the power efficiency. When the number of antennas of T-TRP 170 and / or NT-TRP 172 is sufficient, the random channels between each ED 110 and T-TRP 170 and / or NT-TRP 172 can be close to orthogonal, thereby reducing interference between cells and users and noise impact. The above advantages make large-scale MIMO have broad application prospects.

[0100] A MIMO system may include a receiver connected to a receive (Rx) antenna, a transmitter connected to a transmit (Tx) antenna, and a signal processor connected to the transmitter and the receiver. Each of the Rx antenna and the Tx antenna may include multiple antennas. For example, the Rx antenna may have a uniform linear array (ULA) antenna, in which multiple antennas are arranged in rows at even intervals. When a radio frequency (RF) signal is transmitted through the Tx antenna, the Rx antenna may receive a signal reflected and returned from a target in front.

[0101] A non-exhaustive list of possible elements or possible configurable parameters in some embodiments of a MIMO system includes: a panel; and a beam.

[0102] A panel is a unit of an antenna group or antenna array or antenna subarray, which can independently control a Tx beam or an Rx beam.

[0103] A beam may be formed by performing amplitude and / or phase weighting on data sent or received by at least one antenna port. A beam may be formed by other methods, such as adjusting relevant parameters of an antenna unit. A beam may include a Tx beam and / or an Rx beam. The transmit beam indicates the distribution of signal strength formed in different directions in space after the signal is transmitted through the antenna. The receive beam indicates the distribution of signal strength of wireless signals received from the antenna in different directions in space. The beam information may include a beam identifier, an antenna port identifier, a channel state information reference signal (CSI-RS) resource identifier, an SSB resource identifier, a sounding reference signal (SRS) resource identifier, or other reference signal resource identifiers.

[0104] If the choice is between single-base sensing and multi-base sensing, it can be considered that in order to realize the concept of "network as sensor" in future wireless communication systems, multi-base sensing configuration is the most suitable choice. Some existing proposals can be understood as attempts to take advantage of multi-base sensing to serve future wireless communication networks. One existing proposal is based on a scheme using dedicated sensing pilot signals. Another existing proposal is based on a scheme that reuses communication pilot signals as sensing pilot signals. Exemplary communication pilot signals include CSI-RS, demodulation reference signal (DMRS), phase tracking reference signal (PTRS) and positioning reference signal (PRS). Schemes based on the use of dedicated sensing pilot signals may be considered to have an unfavorable amount of overhead. In schemes based on reusing communication pilots, communication pilots may be considered too sparse to achieve processing gain that provides appropriate sensing performance.

[0105] Aspects of the present application are directed to schemes for implementing a multistatic sensing scheme in a manner that aims to avoid the disadvantages of prior proposed schemes, which have been outlined above.

[0106] Various aspects of the present application relate to using communication data as perception pilot signals. One advantage of using communication data as perception pilot signals is that perception overhead is reduced. Another advantage of using communication data as perception pilot signals is that there is processing gain. The processing gain can be attributed to a large number of data symbols. A large number of data symbols can be displayed to achieve relatively simple fast Fourier transform (FFT)-based reception. Another advantage of using communication data as perception pilot signals is that the communication data can be viewed as similar to a large-sized random data set. Using a large-sized random data set to perceive pilot signals may prove to have advantages in terms of automatic ambiguity. It is known that automatic ambiguity is a key performance indicator in terms of delay estimation and Doppler frequency offset estimation.

[0107] Various aspects of the present application relate to various communication-assisted sensing schemes, in which user equipment can use communication signals for sensing purposes.

[0108] Figure 6 An exemplary communication scheduling region 600 is shown. The exemplary communication scheduling region 600 is defined as a grid indexed by bandwidth parts (BWP1, BWP2, BWP3, BWP4) and time slots (TS1, TS2, TS3, TS4, TS5, TS6). It should be noted that a common communication scheduling region can be defined as indexed by K bandwidth parts, where K is not necessarily equal to 4. Similarly, a common communication scheduling region can be defined as indexed by M time slots, where M is not necessarily equal to 6. Figure 6 The exemplary communication schedule region 600 includes six data block transmissions (DB0, DB1, DB2, DB3, DB4, DB5).

[0109] Figure 7 An example of a signal flow between UE 110 and TRP 170 is shown in a signal flow diagram. Initially, UE 110 may send (step 702) a capability report to TRP 170. The capability report may include an indication of buffering capabilities at UE 110 and an indication of perceived processing capabilities at UE 110. The indication of perceived processing capabilities may include one or more of: an indication of perceived processing delay; an indication of perceived bandwidth processing capabilities; an indication of perceived duration processing capabilities.

[0110] In response to receiving the capability report, TRP 170 may send (step 704) a perception report configuration to UE 110. For example, TRP 170 may send (step 704) the perception report configuration using RRC signaling. UE 110 may use the perception report configuration to define the content of its perception reports and / or the manner in which the perception reports are sent, as further described below. For example, the perception report configuration may define the behavior of UE 110 in the event of a decoding error, and whether the perception report is merged with feedback of the decoding error or sent separately.

[0111] TRP 170 may then send (step 706) information defining the perception area. For example, TRP 170 may send (step 706) the perception area definition using DCI. It should be noted that the perception area may be defined to include the entire given communication scheduling area (see Figure 6 The exemplary communication scheduling area 600 of FIG. 100 or a subset of a given communication scheduling area. The sensing area definition may be based on a capability report sent (step 702) by the UE 110. The sensing area definition may additionally or alternatively be based on a specified "quality of sensing" (QoSe) parameter. The communication scheduling area may include N data block transmissions allocated for sensing detection.

[0112] TRP 170 may define (step 708) a sensory feedback channel.

[0113] When defining (step 708) the sensing feedback channel, the TRP 170 may consider the length dimension of the sensing area, the self-reported UE processing delay, the sensing report type, and the acceptable sensing delay parameter.

[0114] Next, TRP 170 may send (step 710) to UE 110 an indication of the definition of a sensory feedback channel.

[0115] The transmission of the definition of the sensory feedback channel (step 710) may be accomplished using DCI.

[0116] In response to receiving (step 712) the scheduled transmission from TRP 170, UE 110 may process the received scheduled transmission. Processing the received scheduled transmission may include performing (step 714) decoding of data of the scheduled transmission, thereby obtaining decoded data. UE 110 may buffer the decoded data. Processing the received scheduled transmission may include UE 110 performing (step 716) a sensing parameter estimation operation. UE 110 may perform (step 716) a sensing parameter estimation operation based on information about the decoded data of the data block transmission allocated for sensing detection.

[0117] Processing the received scheduled transmission may also include UE 110 sending (step 718) a perception report to TRP 170. UE 110 may employ a perception feedback channel as described in the received definition. UE 110 may send (step 718) the perception report using PUSCH.

[0118] The perception report may be sent in combination with other information or may be sent separately. For example, the other information may be communication related feedback, in which case the perception report may be combined with the communication related feedback and the combined information may be sent on a communication related feedback channel. When the perception report is to be sent separately, the perception report may be sent on a dedicated perception report channel. The combination of the perception report with other information may depend on the timing relationship between the perception report and the other information.

[0119] The UE capability report sent in step 702 may include an indication of the ability to buffer data after decoding (step 714) a scheduled transmission received (step 712) at UE 110. In a first scenario, UE 110 does not have the ability to buffer data blocks that have been received (step 712) and decoded (step 714). In this first scenario, UE 110 may be configured to perform (step 716) a perception parameter estimation operation on each individual decoded data block in response to the data block being decoded (step 714). In a second scenario, UE 110 has the ability to buffer data blocks that have been received (step 712) and decoded (step 714). In practice, UE 110 may have the ability to buffer multiple decoded data blocks. UE 110 may be configured to perform (step 716) a perception parameter estimation operation on multiple decoded data blocks.

[0120] The UE capability report sent in step 702 may include an indication of the capability to perform multiple BWPs and parallel baseband perceptual parameter estimation after the data block has been decoded (step 714). In a first scenario, UE 110 does not have the capability to perform (step 716) perceptual parameter estimation on multiple BWPs. Accordingly, UE 110 may be configured to perform (step 716) perceptual parameter estimation on a data block decoded from a particular BWP. In a second scenario, UE 110 has the capability to perform (step 716) perceptual parameter estimation on a decoded (step 714) data block jointly on multiple BWPs.

[0121] The UE capability report sent in step 702 may include an indication of processing capabilities. The indication of processing capabilities may include an indication of perceived bandwidth processing capabilities. The indication of processing capabilities may also include an indication of time processing capabilities. The indication of processing capabilities may also include an indication of the possible complexity of perceived reception. The indication of the possible complexity of perceived reception may be represented by the FFT size that the receiver can handle and whether the receiver can use a super-resolution algorithm. The UE capability report sent in step 702 may include an indication of the UE power mode. The indication of perceived processing delay may be understood to be related to how much power budget the UE has available to perform the perception operation (after decoding its scheduled data blocks). The indication of the UE power mode may indirectly indicate other capabilities, such as processing capabilities, multi-BWP processing capabilities, and receiver complexity capabilities.

[0122] The UE capability report sent in step 702 may include an indication of the perception processing delay. The indication of the perception processing delay may be understood to relate to the amount of additional delay (time taken) that may be associated with the UE 110 performing (step 716) the perception parameter estimation to obtain the perception report. Since the delay is already associated with the time taken by the UE 110 to decode (step 714) the received data block, this delay is referred to as "extra" delay.

[0123] Figure 8 Shown is the indication Figure 6 A sensing area 800 of a subset of the exemplary communication scheduling area 600 .

[0124] Fig. 9 Exemplary steps in a method of processing received scheduled transmissions performed by a UE 110 without buffering capability and multi-BWP processing capability are shown. Due to the lack of buffering capability and multi-BWP processing capability, the UE 110 may be configured to perform perceptual parameter estimation for each decoded data block separately. Fig. 9 The method is represented as a plurality of methods performed on a plurality of exemplary data blocks. The exemplary data blocks are referenced by data block indexes DB0 and DB(G-1). Figure 8 As shown, not all data blocks may be designated for sensing.

[0125] Fig. 9 The various methods shown are based on the assumption that the data block DB0 in the first time slot is designated for sensing and the data block DB(G-1) in the Gth time slot is designated for sensing. In addition, Fig. 9 The various methods shown are based on the assumption that OFDM-based waveforms are used for communication / sensing. Fig. 9The various methods shown are based on the assumption that UE 110 does not have multi-BWP capability, and therefore, G DBs should be scheduled on G time slots for UE 110. In general, this is not the case. In general, multiple DBs can be scheduled on the same time slot for UE 110.

[0126] In the first time slot, UE 110 obtains (step 902-0) a first receiving matrix Y0. The first receiving matrix Y0 can be understood as indicating the time domain signal y(t) received by cyclic prefix removal and FFT operation. After waveform demodulation is applied, the set of complex symbols received on each resource element (RE). Next, UE 110 decodes (step 904-0) the first data block referenced by the data block index DB0. After determining (step 906-0) that the decoding is successful, UE 110 reconstructs (step 908-0) the first transmitting matrix X0. Reconstructing the first transmitting matrix X0 includes applying forward error correction to the decoded information bits, modulating the coded bits, and mapping the modulated symbols to the resource elements corresponding to the time / frequency region allocated for the first data block. Next, UE 110 can determine (step 910-0) a first channel matrix Z0. The channel matrix can be determined (step 910-0) as a two-dimensional FFT of the quotient of the receiving matrix and the reconstructed transmitting matrix. That is, Z0 = FFT 2D (Y0 / X0). Based on the first channel matrix, UE 110 may estimate (step 912-0) various perception parameters, including a delay parameter and a Doppler frequency shift parameter. Next, UE 110 may send (step 914-0) a first perception report to TRP 170. The first perception report may include some or all of the perception parameters that have been determined (step 912-0) and may be associated with data block index DB0.

[0127] Fig. 9 1 shows two sensing methods for data blocks received in two corresponding time slots (a first time slot and a Gth time slot) among multiple sensing methods for data blocks received in multiple corresponding time slots. Multiple time slots may include: Figure 6 As shown, all time slots when sensing occurs based on all data blocks will be used. Multiple time slots may include Figure 8 As shown, a subset of time slots when sensing will occur based on a subset of data blocks.

[0128] In the Gth time slot, UE 110 obtains (step 902-G-1) the Gth receiving matrix Y G-1 . Obtain (step 902-G-1) the Gth receiving matrix Y G-1This can be implemented in a manner similar to the manner of obtaining (step 902-0) the first receiving matrix Y0 described above. Next, UE 110 decodes (step 904-G-1) the G-th data block referenced by the data block index DB(G-1). After determining (step 906-G-1) that the decoding is successful, UE 110 reconstructs (step 908-G-1) the G-th transmitting matrix X G-1 . Reconstruct (step 908-G-1) the Gth transmission matrix X G-1 This may be implemented in a manner similar to the manner of reconstructing (step 908-0) the first transmit matrix X0 described above. Next, UE 110 may determine (step 910-G-1) the Gth channel matrix Z G-1 The Gth channel matrix can be determined (step 910-G-1) as the two-dimensional FFT of the quotient of the receive matrix and the reconstructed transmit matrix. That is, Z G-1 =FFT 2D (Y G-1 / X G-1 ). Based on the G-th channel matrix, UE 110 may estimate (step 912-G-1) various perception parameters. Next, UE 110 may send (step 914-G-1) a G-th perception report to TRP 170. The G-th perception report may include some or all of the perception parameters that have been determined (step 912-G-1) and may be associated with data block index DB(G-1).

[0129] Fig.10 Shown by Fig. 9 The exemplary steps in the method of processing a received scheduled transmission performed by a method dedicated to UE 110 compared to a UE 110 with buffering capability and multi-BWP processing capability. Due to the buffering capability and multi-BWP processing capability, UE 110 can be used to jointly perform perception parameter estimation for multiple decoded data blocks. Fig.10 The method is shown as a plurality of methods performed on a plurality of exemplary data blocks. Fig. 9 Compared with the various methods shown, Fig.10 The last few steps of the various methods shown are the same. The exemplary data blocks are referenced by data block indices DB0 and DB(G-1). Figure 8 As shown, not all data blocks may be designated for sensing.

[0130] In the first time slot, UE 110 acquires (step 1002-0) a first reception matrix Y0. Next, UE 110 decodes (step 1004-0) a first data block referenced by data block index DB0. After determining (step 1006-0) that the decoding has been successful, UE 110 caches (step 1007-0) the first reception matrix Y0.

[0131] In the Gth time slot, UE 110 obtains (step 1002-G-1) the Gth receiving matrix Y G-1 . Next, UE 110 decodes (step 1004-G-1) the G-th data block referenced by the data block index DB(G-1). After determining (step 1006-G-1) that the decoding is successful, UE 110 caches (step 1007-G-1) the G-th received matrix Y G-1 .

[0132] Next, UE 110 may combine all transmit matrices [X0, ..., X G-1 ] to determine (step 1009) the overall transmit matrix X. UE 110 may also combine all receive matrices [Y0, ..., Y G-1 ] to determine (step 1009) the overall receiving matrix Y. The receiving matrix [Y0,…,Y G-1 Each of the transmission matrices [X0, ..., X0] can be obtained in a manner similar to the manner in which the first receiving matrix Y0 is obtained (step 902-0) as described above. G-1 Each of the transmission matrices X can be reconstructed in a manner similar to the manner of reconstructing the first transmission matrix X0 described above (step 908-0). g and the receiving matrix Y g The process of (g=0, .., G-1) may include inserting 0 matrices for time / frequency resources ("empty regions") on which no data blocks are transmitted. In this case, the size of the 0 matrices may be obtained according to the number of OFDM symbols and the number of subcarriers corresponding to the empty regions.

[0133] Next, UE 110 may determine (step 1010) an overall channel matrix Z. The overall channel matrix Z may be determined (step 1010) as the two-dimensional FFT of the quotient of the overall receive matrix Y and the overall transmit matrix X. That is, Z = FFT 2D (Y / X). Based on the overall channel matrix Z, UE 110 may estimate (step 1012) various perception parameters. Next, UE 110 may send (step 1014) an overall perception report to TRP 170. The overall perception report may include some or all of the perception parameters determined (step 1012).

[0134] Various aspects of the present application involve TRP 170 scheduling the configuration of a perceptual feedback reporting channel and sending the configuration of the perceptual feedback reporting channel via DCI to UE 110. Since perceptual detection is associated with data decoding, there are many options for the content of the perceptual feedback reporting channel.

[0135] In the first option, the TRP 170 can be Fig.11As shown, a PDCCH 1104 including instructions for UE 110 is sent. It should be noted that a data block (not shown) to be used for perception detection at UE 110 can be carried by PDSCH 1102. The instructions can indicate to UE 110 that a perception feedback reporting channel is bundled with future transmissions as part of the HARQ protocol. In the case where the perception report is associated with each individual HARQ process, the perception feedback reporting channel can be defined separately for each HARQ process. In this case, the instructions include the perception reporting resources 1110 (in the time domain and frequency domain) allocated by TRP 170 for each perception feedback reporting channel. Generally, the instructions, in particular the perception reporting resources, can be transmitted to UE 110 in a new field of the DCI in PDCCH 1104. Subsequently, after a delay associated with decoding and perception detection, UE 110 can send PUSCH 1106, where UE 110 includes HARQ feedback 1108. In the same PUSCH 1106 , UE 110 may use perception reporting resources 1110 allocated by TRP 170 to send perception feedback reports.

[0136] exist Fig.12 In the exemplary table 1200 of FIG. 1104 , the number of bits is associated with each of the plurality of fields of the DCI in the PDCCH 1104. It is known that the DCI includes UL resource specifications in the frequency domain and / or time domain for the HARQ feedback 1108 for a particular number of HARQ processes. Fig.12 The exemplary table 1200 in FIG. 1 differs from the conventional UL resource specification in that: Fig.12 The exemplary table 1200 in includes specifications of the perception reporting resources 1110 in the frequency domain and / or time domain for the perception feedback report channel transmission. Multiple perception reporting resources 1110 per HARQ process may be defined for the case where decoding errors occur in certain data blocks.

[0137] In a second option, the TRP 170 may be Fig.13 As shown, a PDCCH 1304 including instructions for UE 110 is transmitted. It should be noted that a data block (not shown) to be used for perception detection at UE 110 may be carried by PDSCH 1302. The instructions may indicate to UE 110 that a perception feedback report channel is to be transmitted separately from future transmissions as part of the HARQ protocol. In the case where the perception report is associated with each individual HARQ process, a perception feedback report channel may be defined separately for each HARQ process. In contrast, in Fig.13In the illustrated case, the instruction includes the perception reporting resources 1310 (in the time and frequency domains) allocated by the TRP 170 for the perception feedback reporting channel. In general, the instruction, in particular the perception reporting resources, may be transmitted to the UE 110 in a new field of the DCI in the PDCCH 1304. Subsequently, after a delay associated with decoding and perception detection, the UE 110 may send a first PUSCH 1306-0, in which the UE 110 includes the HARQ feedback 1308. In a second PUSCH 1306-1, the UE 110 may use the perception reporting resources 1310 allocated by the TRP 170 to send the perception feedback reporting channel. It should be noted that in Fig.13 In the example embodiment, the HARQ feedback 1308 precedes the perception report in the perception report resource 1310 in time. However, this is not necessarily the case. In fact, it is contemplated that the perception report in the perception report resource 1310 may precede the HARQ feedback 1308 in time.

[0138] The second option may be considered to be mainly applicable to the scenario where the UE 110 sends a single aggregated awareness report for all decoded data blocks in a given awareness area.

[0139] In a second option, the perception feedback reporting channel may use the perception reporting resource defined using a new field in the UL DCI (format 0_0 or 0_1). That is, the UE 110 may include the perception feedback reporting channel in the second PUSCH 1306-1.

[0140] exist Fig.14 In the exemplary table 1400 of FIG. 1400 , the number of bits is associated with each of the plurality of fields of the DCI in the PDCCH 1304. It is known that the DCI includes UL resource specifications in the frequency domain and / or time domain for the HARQ feedback 1308 for a particular number of HARQ processes. Fig.14 The exemplary table 1400 in FIG. 1 differs from the conventional UL resource specification in that: Fig.14 The exemplary table 1400 in FIG. 1400 includes specifications of the perception reporting resources 1310 in the frequency domain and / or time domain for the perception feedback reporting channel transmission. Fig.12 Compared to the exemplary table 1200 in Fig.14 In the exemplary table 1400 in FIG. 14 , the UL awareness reporting resource specification is not related to a specific HARQ process.

[0141] In the event that the UE 110 experiences decoding errors (NACKs) for some data blocks, it is understood that sensing may not be performed. In response to experiencing decoding errors (NACKs), the UE 110 may operate in a manner defined in a configuration. The configuration may be transmitted to the UE using RRC signaling via SensingReportConfiguration. The configuration may include instructions regarding whether the UE 110 is to bundle sensing feedback reports with HARQ processes or what actions to take in case of decoding errors.

[0142] In an exemplary configuration (corresponding to sensingNACKreportconfiguration0), UE 110 may ignore unsuccessful decoding of data blocks in the sensing feedback report.

[0143] In another exemplary configuration (corresponding to sensingNACKreportconfiguration1) and as Fig.15 As shown, UE 110 may send a perception feedback report corresponding to the NACK data block in a manner separate from a perception feedback report corresponding to the ACK data block after the NACK data block is finally successfully decoded after retransmission.

[0144] Fig.15 It is shown that the UE 110 may receive an initial transmission 1502-0 of a first data block DB0. After failing to correctly decode the initial transmission 1502-0 of the first data block DB0, the UE 110 may send a first PUSCH 1506-0. The first PUSCH 1506-0 may include a NACK 1504N to indicate to the TRP 170 that the first data block DB0 has not been correctly decoded. Although the first PUSCH 1506-0 includes a perception reporting resource 1508, the UE 110 causes the perception reporting resource 1508 to remain unused because the UE 110 does not have any perception estimation results to report. Subsequently, the UE 110 may receive a retransmission 1502-1 of the first data block DB0_RV1. After correctly decoding the first data block DB0 with the aid of the retransmission 1502-1 of the first data block DB0_RV1, the UE 110 may send a second PUSCH 1506-1. The second PUSCH 1506-1 may include an ACK 1504A to indicate to the TRP 170 that DB0 has been correctly decoded and the retransmission 1502-1 of the first data block DB0_RV1. The second PUSCH 1506-1 may also include two perceptual feedback channels: a first perceptual feedback channel 1510-0 for the initial transmission 1502-0 of the first data block DB0, and a second perceptual feedback channel 1510-1 for the retransmission 1502-1 of the first data block DB0_RV1.

[0145] In another exemplary configuration (corresponding to sensingNACKreportconfiguration2) and as Fig.16 As shown, UE 110 may send the perception feedback report together in one reporting opportunity.

[0146] Fig.16 It is shown that the UE 110 may receive an initial transmission 1502-0 of a first data block DB0. After failing to correctly decode the initial transmission 1502-0 of the first data block DB0, the UE 110 may send a first PUSCH 1506-0. The first PUSCH 1506-0 may include a NACK 1504N to indicate to the TRP 170 that the first data block DB0 has not been correctly decoded. Although the first PUSCH 1506-0 includes a perception reporting resource 1508, the UE 110 causes the perception reporting resource 1508 to remain unused because the UE 110 does not have any perception estimation results to report. Subsequently, the UE 110 may receive a retransmission 1502-1 of the first data block DB0_RV1. After correctly decoding the first data block DB0 with the aid of the retransmission 1502-1 of the first data block DB0_RV1, the UE 110 may send a second PUSCH 1506-1. The second PUSCH 1506-1 may include an ACK 1504A to indicate to the TRP 170 that DB0 was correctly decoded and the retransmission 1502-1 of the first data block DB0_RV1. The second PUSCH 1506-1 may also include an aggregated perception feedback channel 1610 for the initial transmission 1502-0 of the first data block DB0 and the retransmission 1502-1 of the first data block DB0_RV1.

[0147] Various aspects of the present application are directed to a scenario in which UE 110 receives multiple PDSCH transmissions associated with multiple corresponding spatial layers from TRP 170.

[0148] It is known that two signals received after being transmitted from the same antenna port of a given device may experience the same wireless channel. In contrast, two signals received after being transmitted from two different antenna ports of a given device may experience different wireless conditions. It should be noted that in some cases, two signals received after being transmitted from two different antenna ports may experience a wireless channel with common properties. In these cases, it can be said that the antenna ports are quasi-co-located (QCL). In fact, efforts can be made to enhance the possibility of quasi-co-location of two or more PDSCH transmissions. This attempt can be called a QCL configuration.

[0149] In the absence of a QCL configuration for multiple PDSCH transmissions, UE 110 may process each received PDSCH transmission individually. UE 110 may process each received PDSCH transmission as described above.

[0150] However, in case there is a QCL configuration for two PDSCH transmissions sent from the same antenna port or on the same beam, for example at TRP 170, UE 110 may choose to process the PDSCH transmissions for sensing purposes and to send sensing feedback reporting purposes.

[0151] Consider this situation, there is a first communication scheduling region 1700A for a first group of PDSCH transmissions and a second communication scheduling region 1700B for a second group of PDSCH transmissions, such as Fig.17 Given that Fig.17 It should be noted that the resources (BWP1, TS3) scheduled for a data block (DB2) in the first communication scheduling region 1700A are the same as the resources (BWP1, TS3) scheduled for the same data block (DB2) in the second communication scheduling region 1700B. These resources may be referred to as overlapping resources.

[0152] In a first option, UE 110 may process the received quasi co-located PDSCH transmissions and send a single perception feedback report for all received quasi co-located PDSCH transmissions. In the first option, the perception feedback report is unlikely to be associated with a specific HARQ process.

[0153] In the second option, UE 110 may process the received quasi-co-located PDSCH transmissions and send a single perception feedback report corresponding to each PDSCH transmission. In the second option, when UE 110 is scheduled on overlapping resources, it is possible that one data block from the first PDSCH transmission (DB2 in the first communication scheduling region 1700A, see Fig.17 ) is successfully decoded, and another data block from the second PDSCH transmission (DB2 in the second communication scheduling region 1700B, see Fig.17) was not successfully decoded. In this case, UE 110 may report perception based on processing data block DB2 from the first PDSCH transmission. Alternatively, UE 110 may also recognize that the data block from the first PDSCH transmission has been successfully decoded even though it is interfered with by data in the second PDSCH transmission. Therefore, for perception purposes, UE 110 may delay processing of the data block from the first PDSCH transmission. Subsequently, UE 110 may also delay sending a perception feedback report related to the data block from the first PDSCH transmission. UE 110 may wait for a retransmission of data block DB2 from the second PDSCH transmission. After successfully decoding data block DB2 from the second PDSCH transmission, UE 110 may process the data block from the first PDSCH transmission for perception purposes. UE 110's processing of the data block from the first PDSCH transmission may include interference removal. That is, the information obtained by successfully decoding data block DB2 from the second PDSCH transmission may indicate that UE 110 may remove interference from data in data block DB2 from the second PDSCH transmission from the data block from the first PDSCH transmission. Similarly, information obtained by successfully decoding data block DB2 from the first PDSCH transmission may indicate that UE 110 may remove interference from data in data block DB2 from the first PDSCH transmission from the data block from the second PDSCH transmission. Due to interference mitigation, the receiver experiences a higher effective signal to noise plus interference ratio (SINR) condition for both data blocks, and thus this process may help obtain more accurate perceptual estimates corresponding to both data blocks.

[0154] All these UE behaviors can be defined as additional SensingReportConfiguration parameters (via RRC signaling) to indicate the UE behavior in this scenario.
