Description
Communication method and device
[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on December 26, 2023, with application number 202311818500.1 and application name “Communication Method and Device”, the entire contents of which are incorporated by reference into this application. Technical Field
[0002] The present application relates to the field of communication technology, and in particular to a communication method and device. Background Art
[0003] The deep integration of information technology, mobile communication technology, artificial intelligence and big data technology is driving the evolution of fifth-generation mobile communication technology (5G) to sixth-generation mobile communication technology (6G) at both the technical and business levels. ITU-2030 plans to integrate communication and perception as one of the main considerations for 6G.
[0004] 5G New Radio (NR) utilizes a unified high- and low-frequency air interface design and introduces hybrid digital-analog beamforming. Effective communication between devices, and between devices and network equipment, requires alignment of transmit and receive beams. For integrated interawareness scenarios, a solution that fuses communication and perception beams is urgently needed. Summary of the Invention
[0005] The present application provides a communication method and device that can achieve effective fusion of communication beams and perception beams in a synaesthesia integration scenario.
[0006] In a first aspect, the present application provides a communication method, which includes: determining perception resources, communication resources, a perception beam and a communication beam, wherein the perception beam is used to send a perception signal, and the communication beam is used to send a communication signal; on the perception beam, a first transmission block is sent through the perception resource, the first transmission block includes perception beam indication information, and the perception beam indication information indicates that the transmission beam of the first transmission block is the perception beam; on the communication beam, a second transmission block is sent through the communication resource, and the second transmission block is used for communication.
[0007] Regarding the perception beam, in one example, the perception beam can be determined based on the spatial direction of the perceived object. In another example, the transmitter periodically performs beam scanning in different directions. In this scenario, the beam corresponding to the direction currently being scanned is determined as the perception beam. In yet another example, the transmitter repeatedly transmits perception signals in a directionally determined manner. In this scenario, the beam corresponding to the direction is determined as the perception beam.
[0008] When the method is performed by a user equipment (UE), in one possible implementation, the first transmission block includes sidelink control information (SCI), which carries sensing beam indication information. For example, the sensing beam indication information may be located in a payload of the SCI. In one possible implementation, the first transmission block is a side synchronization signal block (S-SSB).
[0009] When the execution subject of the method is a network device, in one possible implementation, the first transmission block includes downlink control information (DCI), and the DCI carries sensing beam indication information. In one possible implementation, the first transmission block is an SSB.
[0010] In a possible implementation, the first transmission block and the second transmission block are the same transmission block, the sensing resources and the communication resources are the same, and the sensing beam and the communication beam are the same.
[0011] In this implementation, the communication resources and the perception resources are the same, and the communication beam and the perception beam are the same. It can be understood that there is no difference between communication and perception in terms of time-frequency resources and beam resources, and the time-frequency and space resources of the two are integrated.
[0012] In a possible implementation, the sensing resources and the communication resources are the same, and the sensing beam and the communication beam are different.
[0013] In this implementation, since the communication resources and the perception resources are the same, the fusion of the communication beam and the perception beam can be achieved through the spatial division method of the beam domain.
[0014] In a possible implementation, the sensing resources and the communication resources are different, and the sensing beam and the communication beam are the same or different.
[0015] In a possible implementation, when the first transport block is retransmitted multiple times, the beams indicated by the perceived beam indication information of the retransmitted first transport blocks may contain the same beam or may not contain the same beam.
[0016] Its effective effect is that it can indicate different perception beams on different transmission symbols or time slots by utilizing the communication retransmission mechanism, thereby improving perception accuracy while ensuring communication performance. The improvement in perception accuracy depends on the different frequency resources of retransmission, which is equivalent to increasing the bandwidth.
[0017] In one possible implementation, the communication resources are the same as the time domain resources in the perception resources, and the perception beam and the communication beam are different. The method also includes: determining the power of the perception beam and the power of the communication beam based on target parameters, and the target parameters include: service priority, transmission block priority or the spatial distance between the perception beam and the communication beam; on the perception beam, the process of sending the first transmission block through the perception resource includes: on the perception beam, sending the first transmission block through the perception resource according to the power of the perception beam; on the communication beam, the process of sending the second transmission block through the communication resource includes: on the communication beam, sending the second transmission block through the communication resource according to the power of the communication beam.
[0018] For example, services may include perception and / or communication services. For example, with respect to service priority, if the priority of the communication service is higher than that of the perception service, the power of the communication transmit beam may be higher than that of the perception transmit beam. If the priority of the communication service is lower than that of the perception service, the power of the communication transmit beam may be lower than that of the perception transmit beam. With respect to transport block priority, the higher the priority of the transport block, the greater the power of the corresponding transmit beam. With respect to the spatial distance between the perception beam and the communication beam, the closer the spatial distance between the two beams, the greater the power difference between the two beams.
[0019] The beneficial effect is that by allocating power to different sensing beams and communication beams, the leakage interference between different beams can be effectively reduced.
[0020] In a possible implementation, the method further includes: determining a candidate sensing beam set, where the candidate sensing beam set includes at least one candidate sensing beam, and the first transmission block further includes candidate sensing beam indication information, where the candidate sensing beam indication information is used to indicate the candidate sensing beam set.
[0021] The beneficial effect is that the receiving end can determine the perception receiving beam in advance based on the candidate perception beam set indicated by the candidate perception beam indication information, thereby performing a corresponding perception process.

[0081] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.
[0082] The terms "first," "second," and the like in the description, embodiments, claims, and drawings of this application are used solely for descriptive purposes and are not to be construed as indicating or implying relative importance or order. Furthermore, the terms "including," "having," and any variations thereof are intended to cover non-exclusive inclusions, such as, for example, inclusion of a series of steps or units. A method, system, product, or apparatus is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.
[0083] It should be understood that in this application, "at least one (item)" means one or more, and "plurality" means two or more. "And / or" is used to describe the association relationship of associated objects, indicating that three relationships may exist. For example, "A and / or B" can mean: only A exists, only B exists, and A and B exist at the same time, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following items" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b or c can mean: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", where a, b, c can be single or multiple.
[0084] To facilitate understanding, the technical terms involved in the embodiments of the present application are explained below.
[0085] 1.V2X communication
[0086] Cellular vehicle-to-everything (C-V2X) is a V2X communication technology developed based on cellular systems. It leverages and enhances current cellular network functions and elements to achieve low-latency and high-reliability communication between various nodes in the vehicle network.
[0087] Please refer to Figure 1, which is a schematic diagram of a V2X communication scenario provided in an embodiment of the present application. As shown in Figure 1, V2X communication includes vehicle-to-vehicle communication (V2V), vehicle-to-pedestrian communication (V2P), vehicle-to-infrastructure communication (V2I), and vehicle-to-network communication (V2N).
[0088] As cellular systems evolve from the 4th generation mobile communication technology (4G) to 5G, C-V2X evolves from LTE-V2X to NR-V2X (including NR PC5 and NR Uu).
[0089] V2V focuses on vehicle-to-vehicle (SL) communication. Through V2V communication, vehicles on the road can obtain real-time driving information and sensor data from other vehicles, playing a crucial role in enabling autonomous driving. In platooning, the lead vehicle transmits vehicle maneuvering information to the rest of the platoon via V2V, enabling autonomous driving for subsequent vehicles. For extended sensors, upon sensing another vehicle, a vehicle communicates this sensor information to the other vehicles via V2V, addressing the issue of inaccurate environmental perception caused by the limited capabilities of a vehicle's own sensors.
[0090] Furthermore, V2V communication technology can be extended to device-to-device (D2D) communication in any system. D2D communication is also called sidelink (SL) communication.
[0091] 2. Beam
[0092] A beam is a communication resource that creates a unique, directional transmission or reception effect through an antenna array in a transmitter or receiver of a network device or terminal. This effect is similar to the beam formed by a flashlight that focuses light in a single direction. Transmitting and receiving signals using beams can effectively increase signal transmission distance.
[0093] Beams can be divided into transmit beams and receive beams. The technology for forming beams can be beamforming technology or other technical means. Beamforming includes transmit beamforming and receive beamforming. The beamforming technology can be digital beamforming technology, analog beamforming technology, or hybrid digital / analog beamforming technology.
[0094] Transmit beam: The transmitting device sends signals with certain beamforming weights, forming a spatially directional beam. Receive beam: The receiving device receives signals with certain beamforming weights, forming a spatially directional beam.
[0095] Transmitting a signal using a certain transmit beam: transmitting a signal using a certain beamforming weight. Receiving a signal using a receive beam: receiving a signal using a certain beamforming weight. Beamforming may be beamforming in a frequency range (FR) 2.
[0096] Beams generally correspond to resources. For example, when performing beam measurement, the network device measures different beams through different resources, and the terminal device feeds back the measured resource quality, so that the network device can know the quality of the corresponding beam. During data transmission, the beam can also be indicated by its corresponding resource. For example, the network device indicates a transmission configuration indication state (state) through the transmission configuration index (TCI) field in the DCI, and the UE determines the beam corresponding to the reference resource based on the reference resource contained in the state. Different beams can be considered as different resources, and the same information or different information can be sent using (or through) different beams.
[0097] 3. Resources
[0098] In communication protocols, reference signals are configured as resources. Network equipment allocates each reference signal to the UE as a resource. A resource is a configuration information unit, which typically includes parameters related to the reference signal, such as the reference signal's time-frequency resource location, number of ports, and time domain type (periodic, semi-static, or aperiodic).
[0099] Resources can be uplink signal resources or downlink signal resources. Uplink signals include but are not limited to sounding reference signal (SRS) and demodulation reference signal (DMRS). Downlink signals include but are not limited to channel state information reference signal (CSI-RS), cell specific reference signal (CS-RS), user equipment specific reference signal (US-RS), and synchronization system / physical broadcast channel block (SS / PBCH block). Among them, SS / PBCH block can be referred to as SSB.
[0100] Resources can be configured through Radio Resource Control (RRC) messages. In terms of configuration structure, a resource is a data structure that includes parameters related to the corresponding uplink / downlink signal. For example, the uplink / downlink signal type, the resource element carrying the uplink / downlink signal, the uplink / downlink signal transmission time and period, and the number of ports used to transmit the uplink / downlink signal. Each uplink / downlink signal resource has a unique identifier to identify the downlink signal resource.
[0101] 4. Beam management (BM)
[0102] In 5G NR, it refers to the process by which the 5G base station (the next generation nodeB, gNB) and the UE acquire and maintain the beam set for transmission and reception, thereby achieving high-gain communication with reasonable beam pairs.
[0103] The downlink transmit beam training process between the NR terrestrial radio access network and the universal terrestrial radio access network (UE, Uu) includes the following four technical points:
[0104] 1) Beam sweeping: The process by which a UE sequentially selects beams for transmission or reception in a specified scanning manner within a time period to cover a spatial area.
[0105] 2) Beam measurement: The process by which the UE measures the received beamformed signal.
[0106] 3) Beam reporting: The process by which the UE reports beam measurement results to the network equipment.
[0107] 4) Beam determination: The process by which the UE selects its transmit or receive beam.
[0108] Beam management can include three states. Please refer to Figure 2, which is a schematic diagram of downlink beam management provided in an embodiment of the present application. The operations in each state are as follows:
[0109] P-1: The UE measures the base station's transmit beam set and selects the base station's transmit beam and the UE's receive beam.
[0110] P-2: Based on P-1, the UE measures a smaller set of base station transmit beams to improve the base station's transmit beams.
[0111] P-3: The UE uses different receive beams to measure the transmit beam of the same base station and improve its own receive beam.
[0112] Based on the above four technical points and three state operations, downlink beam management is carried out. Its basic process is as follows: In order to implement the transmit beam training in the P-1 and P-2 working states, the base station (BS) will S K transmit beams are allocated S CSI-RS resources are generated, and then these CSI-RS resources are sent out through beam scanning. Among these CSI-RS resources, the maximum number of CSI-RS ports is 2. Other uncertain resource mapping information needs to be configured by the BS and indicated to the UE through RRC signaling. At the same time, the BS only sends CSI-RS resources in a single beam direction at a certain moment. The UE performs beam measurement to obtain the CSI-RS reference signal receiving power (RSRP) and obtains the CRI of the CSI-RS. After measuring the RSRP, the UE selects one or several RSRP values and the corresponding CRI by comparison and reports them to the BS on a given time-frequency resource. The BS uses the reported information to determine the transmit beam to be used, and the initial beam selection process is completed.
[0113] Due to the centralized scheduling system of 5G NR, the time domain position, frequency domain position, bandwidth, and period of the CSI-RS in the physical downlink shared channel (PDSCH) can be centrally configured by the base station and RRC resource scheduling, enabling standalone CSI-RS transmission and resource selection, completing the beam training process.
[0114] 5.SL Resources
[0115] Under network coverage, the UE may obtain SL resource pool configuration information and / or SL bandwidth part (BWP) configuration information by receiving system information block (SIB) of the network equipment, cell-level (cell-specific) RRC signaling or terminal device user-level (UE-specific) RRC signaling. The UE may also use pre-configured SL resource pool configuration information or SL BWP configuration information, for example, when there is no network coverage.
[0116] The SL resource pool configuration information includes resource pool resource information, which can be used to indicate the SL resource pool. The SL resource pool can be a collection of time-frequency resources used for sideline communication between UEs. The resources of the SL resource pool may include resources for the UE to send and receive at least one of the following physical channels: physical sidelink control channel (PSCCH), physical sidelink shared channel (PSSCH), physical sidelink discovery channel (PSDCH), physical sidelink feedback channel (PSFCH), and physical sidelink broadcast channel (PSBCH).
[0117] Among them, PSCCH is used to carry SCI; PSSCH is used to carry at least one information such as control information, data, or side CSI feedback information; PSDCH is used to carry SL discovery messages; PSFCH is used to carry side feedback information, and the side feedback information can be used for feedback on data information, which includes hybrid automatic repeat request (HARQ) response feedback information, such as confirmation response (ACK) or negative acknowledgement (NACK), and can also include CSI feedback information, and can also be used to indicate at least one of the following information: energy-saving information, resource auxiliary information (including recommended resources, non-recommended resources, resource collisions, resource reservation conflicts, half-duplex conflicts that have occurred in the past or will occur in the future, etc.); PSBCH is used to carry information related to side synchronization, etc., and the service types carried by PSBCH can include unicast, multicast and / or broadcast communication types.
[0118] The time domain resources of the SL resource pool include one or more time units, and the time unit can be at least one symbol, at least one time slot, at least one mini-slot, at least one subframe, at least one frame, etc. At least one time unit can be continuous in time or discrete. It should be understood that the time domain units in a resource pool are logically continuous. In the embodiment of the present application, the understanding of the definition of symbols, mini-slots, time slots, subframes, and frames can refer to the relevant introduction of the 3rd Generation Partnership Project (3GPP) protocol, and the embodiment of the present application will not be repeated here.
[0119] Please refer to Figure 3, which is a schematic diagram of an SL time slot provided in an embodiment of the present application. Time slots 1 to 8 are time slots that are continuous in time, and such time slots are called physical time slots. Time slots 1, 3, 5, and 8 are configured as time slots belonging to a resource pool. Time slots 1, 3, 5, and 8 on the physical time slots correspond to time slots 1', 2', 3', and 4' in the resource pool. The continuous time slots contained in the resource pool (i.e., time slots 1', 2', 3', and 4') are continuous time slots from the perspective of the resource pool. Such time slots that are logically continuous but not necessarily continuous in time are called logical time slots.
[0120] The frequency domain of the SL resource pool includes one or more frequency domain units, which can be a resource element (RE), several REs, a resource block (RB), several RBs, a subchannel, or several subchannels. The subchannel size, which indicates the number of RBs that are continuous or interlaced in the frequency domain, can be an integer of 10, 12, 15, 20, 25, 50, 75, or 100.
[0121] The SL resource pool configuration information may also include PSCCH configuration information, which includes the number of symbols occupied by the PSCCH in a time slot and the number of RBs occupied by the PSCCH in a subchannel. The SL BWP configuration information may include SL resource pool information, which is used to configure the number of resource pools included in the BWP. The SL BWP configuration information may include SL bandwidth information, which is used to indicate the bandwidth size for SL communication, for example, indicating that the SL bandwidth is 20 megahertz (MHz). The SL BWP configuration information may also include SL symbol information, which is used to indicate the starting SL symbol position on a time slot and the number of continuous SL symbols occupied. The SL BWP configuration information may also include SL subcarrier spacing and cyclic prefix information, which is used to indicate the subcarrier spacing and cyclic prefix used for SL communication. The cyclic prefix indicates an extended cyclic prefix or a normal cyclic prefix. In one possible configuration, the SL BWP configuration information may also include SL resource pool configuration information. In this application, unless the meaning of the time unit is specifically stated, it is described as a time slot, but the time unit is not limited to being a time slot; unless the meaning of the time-frequency domain unit is specifically stated, it is described as a subchannel, but the frequency domain unit is not limited to being a subchannel.
[0122] 6.SL CSI-RS
[0123] The existing FR1 SL CSI-RS is designed based on the CSI-RS. The SL CSI-RS configuration is selected by the transmitting user equipment (TX UE).
[0124] The SL CSI-RS configuration is provided to the receiving user equipment (RX UE) through the near field communication (PC) 5-RRC configuration. The SL CSI-RS configuration may include the resource mapping mode and number of antenna ports for the SL CSI-RS. In NR V2X, the resource mapping of the SL CSI-RS in the PRB is based on the CSI-RS resource mapping mode in the NR Uu, which supports up to 2 antenna ports (e.g., SL in the PSSCH in NR V2X can support up to two streams), and the frequency domain density is 1, that is, one CSI-RS is configured on each resource block (RB).
[0125] The basic function of the SL CSI-RS is to measure the SL channel to calculate the channel rank indicator (RI) and channel quality indicator (CQI), helping the sending UE determine parameters such as the transmission mode, modulation and coding scheme (MCS), and code rate.
[0126] Please refer to Figure 4, which is a schematic diagram of the SL time slot structure in Rel-16 provided in an embodiment of the present application. The SL time slot structure includes: automatic gain control (AGC), PSCCH, PSSCH and DMRS, etc. The SL CSI-RS only supports unicast transmission and is sent along with the data in the PSSCH area of the transmit time slot. At the same time, it is not transmitted on symbols containing PSCCH, second-level SCI or PSSCH DMRS. Each PRB in the PSSCH uses the same pattern for the SL CSI-RS.
[0127] 7.PSSCH time and frequency resources
[0128] The SCI of the NR SL system is divided into first-level SCI and second-level SCI. The first-level SCI is carried on the PSCCH, and the second-level SCI is carried on the corresponding PSSCH. The first-level SCI is used to schedule the second-level SCI and PSSCH. Since SL is a distributed system, all UEs need to correctly decode the first-level SCI before they can decode the second-level SCI and PSSCH. In order to reduce the complexity of UE's blind detection of PSCCH, the resource location of PSCCH is relatively fixed, and the first-level SCI format information carried is also relatively unique, that is, the UE does not need to blindly detect the time-frequency resource location where the PSCCH is located, nor does it need to blindly detect SCI of different formats. The UE only needs to detect whether there is a first-level SCI at the fixed PSCCH time-frequency resource location.
[0129] Please refer to Figure 5, which is a schematic diagram of the time-frequency resource position of a PSCCH provided in an embodiment of the present application. As shown in Figure 5, PSCCH exists in each subchannel on each time slot, that is, the time domain starting position of a PSCCH is the second symbol used for SL transmission on each time slot, and the length is 2 or 3 symbols (determined by the resource pool configuration information), and the frequency domain position is the smallest physical resource block (PRB) index of each subchannel, and the length is at least 10 PRBs (determined by the resource pool configuration information) but not more than the size of the subchannel.
[0130] The frequency domain resource assignment field and the time domain resource assignment field in the first-level SCI are respectively used to indicate the frequency domain and time domain resources of the PSSCH currently (or re)transmitted by the transport block (TB), as well as the frequency domain and time domain resources reserved for up to two retransmissions of the TB. If the UE reserves resources for semi-static PSSCH, the first SCI also includes a periodic reservation resource field, which is used to indicate the resources for periodic reservation transmission of PSSCH, and its value can be configured by the network device, or pre-configured, or pre-defined. In addition, the first-level SCI can also include the priority of the associated PSSCH, and the format and size of the second-level SCI. The first-level SCI can also be used to indicate the MCS of the data payload carried in the associated PSSCH.
[0131] SCI is divided into two levels (first-level SCI and second-level SCI). This allows non-transmitting UEs to decode only the first-level SCI for channel sensing and determine resources reserved by other transmissions. The second-level SCI, on the other hand, provides additional control information required by transmitting UEs. The PSSCH carries the second-level SCI and a data payload consisting of transmission boxes (TBs). The second-level SCI carries information used to decode the PSSCH and support HARQ feedback and CSI reporting. This information indicates the Layer 1 source and destination ID of the transmission, representing the physical layer identifiers of the transmitting UE and the intended recipient (the receiving UE) of the TB. The Layer 1 source ID allows the receiving UE to identify the transmitting UE and, therefore, the PSFCH for HARQ feedback. The second-level SCI also carries a 1-bit new data indicator, which specifies whether the TB sent in the PSSCH corresponds to a new data transmission or a retransmission. The HARQ process ID is also included in the second-level SCI to identify the TB. The second-level SCI also indicates whether HARQ feedback for the PSSCH is enabled or disabled.
[0132] 8. Resource Allocation Model
[0133] Rel-16 defines two resource allocation modes for the PC5 interface: Mode 1 and Mode 2. In Mode 1, the base station allocates transmission resources to V2X via the Uu interface. Therefore, UEs operating in Mode 1 must be within network coverage. SL spectrum resources can be shared with uplink communication resources. In SL communication, Mode 1 and Mode 2 can be allocated to different resource pools or share a resource pool. Resource pool sharing improves resource utilization efficiency, but it can also easily cause conflicts between Mode 1 and Mode 2. Therefore, Mode 1 UEs notify Mode 2 UEs of their allocated resources for future transmissions.
[0134] Mode 2 is a user-selected resource mode. In Mode 2, the transmission resources of the transmitting UE are independent of the base station. The transmitting UE selects transmission resources within the resource selection window for communication based on the results of its own perception window. Please refer to Figure 6, which is a schematic diagram of the resource selection process of the transmitting UE according to an embodiment of the present application. Figure 6 assumes that the transmitting UE triggers resource selection in time slot n. The specific process is as follows:
[0135] Step 1: Determine the time slot and L subCH The candidate resource R is a unit of continuous sub-channels. x,y , resource selection window [n-T1, n-T2], where, It can be determined based on the following Table 1, where μ SL The subcarrier spacing configured. 2min Less than the remaining packet delay budget (PDB), then T 2min ≤T2≤PDB, otherwise T2=PDB.
[0136] Table 1
[0137] Step 2: Determine the perception window [n-T0, T0 is configured by high-level parameters. It can be determined based on Table 2 below.
[0138] Table 2
[0139] Step 3: Determine the RSRP threshold Th(p i , p j ), the RSRP threshold and the prio of the data to be sent TX , the priority indicated by the received SCI prio RX Regarding Th(p i , p j) is specifically the prio in the RSRP threshold value set configured for the resource pool RX +(prio TX -1)*8 threshold values.
[0140] Step 4: Initialize the available resource set S A , S A Includes all time-frequency resources in the resource selection window.
[0141] Step 5: As shown in Figure 6, from S A The following time-frequency resources are excluded: the time slots of all periodic resource reservations configured in the resource pool corresponding to the unperceived time slots (transmitted time slots) in the perception window.
[0142] Among them, if from S A The excluded time-frequency resources are less than X% of the total resources in the resource selection window, and then re-execute step 4. The value of X% is configured by the resource pool and is consistent with the prio TX related,.
[0143] Step 6: Continue from S A The following time-frequency resources are excluded: when the received first-level SCI is decoded successfully, the RSRP measurement result of the PSSCH DMRS of the time-frequency resource reserved by the first-level SCI is higher than the RSRP threshold determined in step 3, and the time-frequency resource reserved by the first-level SCI is within the resource selection window, the retransmission resources and periodically reserved resources indicated by the first-level SCI.
[0144] Step 7: If S A If the remaining resources in the resource selection window are less than X% of the total resources in the resource selection window, the RSRP threshold determined in step 3 is increased (for example, by 3dB each time), so that S A If the remaining resources are not less than X% of the total resources in the resource selection window, proceed to step 4.
[0145] S A Report to a higher layer, such as the medium access control (MAC) layer.
[0146] In S A Randomly select time-frequency resources (such as r0, r1, r2, ...) for sending data, and re-evaluate the resources (r0, r1, r2, ...) before sending. After re-evaluation, select the time-frequency resources (such as r0, r1, r2, ...) from S A The selected resources (r0′, r1′, r2′, …) are preempted.
[0147] UE-to-UE beam management can use independent / non-standalone CSI-RS (the reference signal SL CSI-RS in the existing FR1 must be unicasted with the data on the PSSCH) as the reference signal for beam training. In the process of using MAC control element (CE) to feedback CSI-RS beams, compared with the distributed centralized management process of the base station and the MAC CE reporting process configured in the existing FR1, considering the resource selection process of the distributed system, the time-frequency position reported by the RX UE MAC CE has potential conflicts, such as half-duplex problems or resource conflicts. Therefore, beam feedback based on SL CSI-RS beam training in SL FR2 needs to be urgently resolved.
[0148] 9. Communication and Perception Integration (abbreviated as Synaesthesia Integration)
[0149] In complex application scenarios, business information processing exhibits highly coupled communication and perception features: 1. Perception and communication overlap in the spatiotemporal domain; 2. Perception and communication functions mutually influence each other; and 3. Communication and perception capabilities share the same requirements for wide-bandwidth spectrum and large-aperture antennas. These characteristics are driving the development of integrated communication and perception technologies, and the simultaneous integration of communication and perception capabilities is a key capability trend in 6G networks.
[0150] As can be seen from the preceding description, current 5G NR utilizes a unified high- and low-frequency air interface design and introduces hybrid digital-analog beamforming. Effective communication between the UE and base station requires alignment of the transmit and receive beams. Communication beam management includes beam measurement reporting, beam indication, and beam failure recovery. In integrated interawareness scenarios, the transmission and reception of sensory signals also require corresponding sensory beam management mechanisms, enabling the integration of sensory and communication beams.
[0151] In a synaesthesia integration scenario, communication signals can interfere with sensory signals. For example, please refer to Figure 7, which is a schematic diagram of a synaesthesia integration scenario provided by an embodiment of the present application. Figure 7 shows two synaesthesia integration scenarios (a) and (b), both of which include a base station 101, a base station 102, a UE 103, a UE 104, and a sensory target. The sensory target can be a dynamic object (e.g., a car) or a static object. In Figure 7, the sensory target is a car.
[0152] Figure 7(a) illustrates the example of base station 101 transmitting and receiving a sensing signal. The reception of the sensing signal faces interference not only between environmental objects but also from uplink communication signals between base station 101 and UE 103, and from communication signals between base station 102 and UE 104. Figure 7(b) illustrates the example of base station 101 transmitting a sensing signal and base station 102 receiving the sensing signal. The reception of the sensing signal faces interference not only between environmental objects but also from uplink communication signals between base station 102 and UE 104, and from communication signals between base station 101 and UE 103.
[0153] An embodiment of the present application provides a communication method, which is used in a synaesthesia integration scenario, allocates communication resources and perception resources at the beam domain granularity, and reduces the interference between communication signals and perception signals while realizing the fusion of communication beams and perception beams. The synaesthesia integration scenario used by this method can be an SL mode2 system in which UEs communicate directly with UEs through a PC5 interface, or a system in which UEs communicate with base stations through Uu ports. Direct communication between UEs includes but is not limited to relay and cooperation between UEs. There may be network coverage or no network coverage in the scenario, and the transmitter or receiver may be within the network coverage range or not. Among them, the SL system can be distributed, with communication connections established between each UE and the base station not participating in the communication; it can also be a centralized scheduling type, with a communication connection established between the base station and the UE. In addition, the embodiment of the present application does not limit the frequency band of communication, for example, it can be FR1 or FR2.
[0154] Please refer to Figure 8, which is a schematic diagram of a communication scenario provided in an embodiment of the present application. Figure 8 shows three communication scenarios (a), (b) and (c). These three communication scenarios all show a base station 201, a vehicle 202 and a vehicle 203, and the vehicle 202 and the vehicle 203 communicate directly through the PC5 interface. In (a) of Figure 8, both the vehicle 202 and the vehicle 203 are within the network coverage. In (b) of Figure 8, the vehicle 202 is within the network coverage, and the vehicle 203 is not within the network coverage. In (c) of Figure 8, both the vehicle 202 and the vehicle 203 are not within the network coverage.
[0155] In the communication method provided in the embodiment of the present application, the two ends of the wireless communication may include a network device and a UE, and the network device and the UE transmit signals through the Uu air interface. Or both ends of the wireless communication may be UEs, and the two UEs transmit signals through the SL air interface. The network devices include but are not limited to: traditional evolved node B (eNB) in the universal mobile telecommunications system (UMTS) / LTE, micro base station eNB in the heterogeneous network (HetNet), base band unit (BBU) and remote radio unit (RRU) in the distributed base station scenario, base band pool (BBU pool) and RRU in the cloud radio access network (CRAN), gNB in 5G NR, etc.
[0156] UE includes, but is not limited to, access terminals, terminal units, terminal stations, mobile stations, mobile stations, remote stations, remote terminals, mobile devices, wireless communication devices, terminal agents, and terminal apparatuses. Access terminals may include, for example, cellular phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), handheld devices with wireless communication capabilities (e.g., mobile phones, foldable electronic devices, handheld computers, and tablet computers), computing devices (e.g., desktop computers, laptop computers, notebook computers, ultra-mobile personal computers, and netbooks), other processing devices connected to wireless modems, vehicle-mounted devices, wearable devices, drones, helicopters, airplanes, ships, robots, and robotic arms, terminal devices in 5G systems, terminal devices in evolved public land mobile networks (PLMNs), augmented reality (AR) devices, virtual reality (VR) devices, artificial intelligence (AI) devices, smart home devices, or smart city devices. The embodiments of the present application do not limit the specific technology and specific device form adopted by the UE.
[0157] Please refer to Figure 9, which is a flow chart of a communication method provided in an embodiment of the present application. The communication method is applied to the sending end in the aforementioned communication scenario, which can be a network device or a UE. The method includes the following steps:
[0158] 301. Determine sensing resources, communication resources, a sensing beam, and a communication beam, where the sensing beam is used to send a sensing signal, and the communication beam is used to send a communication signal.
[0159] Sensing resources refer to sensing time-frequency resources, and communication resources refer to communication time-frequency resources. The UE needs to determine the sensing resources and sensing beams corresponding to each sensing transport block to be sent, as well as the communication resources and communication beams corresponding to each communication transport block to be sent.
[0160] When the transmitting end is a UE, the perception resources and communication resources may be selected by the UE through the aforementioned mode2 process. For example, taking A as the UE executing the method and B as another UE as an example, A listens and decodes the SCI sent by B. The SCI sent by B carries resource indication information, and the resource indication information is used to indicate the time-frequency resources required for B to subsequently send a transmission block. A excludes the time-frequency resources indicated by the SCI in the resource pool (perception resource pool or communication resource pool) and selects time-frequency resources from the remaining available time-frequency resources. When the transmitting end is a network device, the perception resources and communication resources may be configured, preconfigured, defined, or predefined by the network device.
[0161] The communication beam can be determined through the aforementioned beam management process. Regarding the perception beam, in one example, the perception beam can be determined based on the spatial direction of the perception object. In another example, the transmitting end periodically performs beam scanning in different directions. In this scenario, the beam corresponding to the direction currently to be scanned is determined as the perception beam. In yet another example, the transmitting end repeatedly transmits a perception signal in a direction. In this scenario, the beam corresponding to the direction is determined as the perception beam. This embodiment of the present application is not limited to this.
[0162] Before sending a sensing signal, the transmitting end determines the sensing resources and sensing beams allocated for the sensing signal. Before sending a communication signal, the transmitting end determines the communication resources and communication beams allocated for the communication signal. The sensing resources and communication resources can be the same or different, and the sensing beams and communication beams can be the same or different, and this is not limited in this embodiment of the application.
[0163] The perceived resources and communication resources being the same means that the perceived time domain resources and communication time domain resources are the same, and the perceived frequency domain resources and communication frequency domain resources are the same. The perceived resources and communication resources being different means that only the perceived time domain resources and communication time domain resources are different, only the perceived frequency domain resources and communication frequency domain resources are different, or that the perceived time domain resources and communication time domain resources are different, and the perceived frequency domain resources and communication frequency domain resources are different. The same time domain resources can refer to the same time unit.
[0164] 302. Send a first transmission block on a sensing beam using sensing resources, where the first transmission block includes sensing beam indication information, and the sensing beam indication information indicates that a transmission beam of the first transmission block is the sensing beam.
[0165] The receiving end determines that the beam indicated by the perception beam indication information is a perception beam through the perception beam indication information, and further determines that the first transmission block sent by the beam indicated by the information is used for perception, and then performs the corresponding perception measurement process.
[0166] When both the transmitting end and the receiving end are UEs, in one example, the first transmission block may include an SCI, which carries sensing beam indication information. For example, the sensing beam indication information may be located in the payload of the SCI. The SCI may also carry resource indication information, which is used to indicate the sensing resources required by the UE for the next transmission block to be sent. In another example, the first transmission block may be an S-SSB. When the transmitting end is a network device, in one example, the first transmission block may include a DCI, which carries sensing beam indication information. In another example, the first transmission block is an SSB.
[0167] For example, the perception beam indication information can be the frequency resource indicator value (FRIV) of the parameter "frequency resource assignment". Or it can be the time resource indicator value (TRIV) of the parameter "time resource assignment". Or it can also be N_(rsv_period) of the parameter "resource reservation period". The bit size of the perception beam indication information can be configured by the high-level parameter "sl-MaxNumPerReserve" or "sl-ResourceReservePeriodList" (for details, please refer to the 3GPP protocol, and the embodiments of this application will not be described here). For example, the perception beam information can occupy 1 bit, such as "1" represents that the transmitted beam is a perception beam, and "0" represents that the transmitted beam is a non-perception beam.
[0168] The number of first transmission blocks may be one or more, each first transmission block corresponds to a sensing resource and a sensing beam, and the transmitting end sends the first transmission block on the sensing beam corresponding to the first transmission block through the corresponding sensing resource.
[0169] 303. Send a second transmission block on the communication beam through the communication resource, where the second transmission block is used for communication.
[0170] When both the transmitting end and the receiving end are UEs, in one example, the second transport block may include an SCI, which carries resource indication information. The resource indication information is used to indicate the communication resources required by the UE for the next transport block to be transmitted. In another example, the second transport block may be an S-SSB. When the transmitting end is a network device, in one example, the second transport block may include a DCI. In another example, the second transport block is an SSB.
[0171] The number of second transmission blocks can be one or more, each second transmission block corresponds to communication resources and communication beams, and the transmitting end sends the second transmission block through the corresponding communication resources on the communication beam corresponding to the second transmission block.
[0172] The embodiments of the present application can employ different allocations of time-frequency resources and beam resources for different sensing modes, thereby achieving effective integration of sensing beams and communication beams. The following examples illustrate several sensing modes. In the following description, the transmission blocks used for sensing are collectively referred to as first transmission blocks, and the transmission blocks used for communication are collectively referred to as second transmission blocks.
[0173] Example 1: UE-A's self-transmitting and self-receiving sensing mode, UE-A is used to execute the communication method provided in the embodiment of the present application
[0174] Please refer to Figure 10, which is a schematic diagram of a perception mode provided by an embodiment of the present application. UE-A is the TX and RX of the perception signal and the TX of the communication signal. UE-B is the RX of the communication signal. There are objects (targets) to be perceived in both the communication direction and the non-communication direction. Figure 10 shows target1 and target2. For the two cases where the communication object and the perception object are consistent and inconsistent in spatial direction, the embodiment of the present application has different allocations of time-frequency resources and beam resources. The following describes the two cases under the perception mode of Example 1.
[0175] 1. The communication object and the perception object are consistent in the spatial direction: As shown in FIG10 , the perception object within the range of the beam represented by the shadow is consistent with the communication object UE-B in the spatial direction.
[0176] In one example, the first transmission block and the second transmission block are the same transmission block, which can be used for communication and / or perception, and is an integrated sensing and communication (ISAC) transmission block. In this case, the communication resources and the perception resources are the same, and the communication beam and the perception beam are the same. It can be understood that there is no difference between communication and perception in terms of time-frequency resources and beam resources, and the time-frequency and space resources of the two are integrated. Please refer to Figure 11, which is a schematic diagram of a communication resource and a perception resource provided in an embodiment of the present application, and the communication resources and the perception resources overlap.
[0177] At this time, the sensing resources include but are not limited to: AGC or GAP time slot resources for sending data on the communication beam, periodic SSB, PSSCH signals, PSCCH signals, DMRS information, CSI-RS, etc. These resources can be periodic (such as SSB or periodic sidelink data information) or non-periodic (such as non-periodic sidelink data). It can also be a combination of various non-periodic data of sidelink data (such as CSI-RS and DMRS, etc.), and / or a combination of periodic data, and / or a combination of non-periodic and periodic data, etc., and its combined resources can also be periodic and / or non-periodic.
[0178] In another example, the first and second transport blocks are different transport blocks, and the communication resources and sensing resources are different, for example, orthogonal. Please refer to Figure 12, which is a schematic diagram of another embodiment of the present application, illustrating communication resources and sensing resources. The communication resources and sensing resources are orthogonal. Because the communication resources and sensing resources are independent of each other, the communication and sensing processes are interference-free, and the communication beam and sensing beam can be the same or different.
[0179] In an embodiment of this case, when the communication beam and the sensing beam are different and the time domain resources in the sensing resources and the communication resources are the same, power can be allocated to the different sensing beams and communication beams to reduce leakage interference between the different beams. For example, the power of the sensing beam and the power of the communication beam can be determined based on target parameters, including: the priority of the sensing and / or communication services, the transmission block priority, or the spatial distance between the sensing beam and the communication beam. When sending the first transmission block, the first transmission block is sent on the sensing beam using the sensing resources according to the power of the sensing beam. When sending the second transmission block, the second transmission block is sent on the communication beam using the communication resources according to the power of the communication beam. In this way, by adjusting the power between different beams, leakage interference between different beams can be effectively reduced.
[0180] For example, if the communication service has a higher priority than the sensor service, the power of the communication transmit beam can be higher than the power of the sensor transmit beam. If the communication service has a lower priority than the sensor service, the power of the communication transmit beam can be lower than the power of the sensor transmit beam. Regarding transport block priority, the higher the transport block priority, the greater the power of the corresponding transmit beam.
[0181] For the spatial distance between the perception beam and the communication beam, please refer to Figure 13. Figure 13 is a beam diagram provided in an embodiment of the present application. In Figure 13, UE-A has beam 1, beam 2, beam 3, beam 4 and beam 5. Assume that the communication beam includes beam 1, and the perception beam includes beam 3 and beam 5, and their corresponding transmit powers are P1, P3, and P5, respectively. The total transmit power of UE-A is Pmax, Pmax = P1 + P3 + P5 = α*Pmax + β*Pmax + γ*Pmax, (α+β+γ=1). Taking into account the synaesthesia leakage interference between adjacent beams, under the constraint of the total transmit power Pmax, β < γ can be made (because the spatial distance between beam 3 and beam 1 is smaller than the spatial distance between beam 5 and beam 1), so that the interference of beam 3 on beam 1 will be relatively small. Among them, the values of α and β can be set based on the capacity requirements of communication services and perception services. The values of α, β and γ may be configured, preconfigured, defined or predefined by the network device or the UE side.
[0182] In this embodiment, the transmission of the communication signal can be periodic or aperiodic, and the transmission of the perception signal can be periodic or aperiodic, which is not limited in this embodiment of the present application. Please refer to Figures 14 and 15. Figure 14 is a schematic diagram of an implementation of perception provided in an embodiment of the present application, and Figure 15 is a schematic diagram of another implementation of perception provided in an embodiment of the present application. As shown in Figure 14, UE-A periodically sends the first transmission block on different beams. As shown in Figure 15, UE-A periodically sends the first transmission block on the same beam.
[0183] 2. The communication object and the perception object are inconsistent in spatial direction: As shown in Figure 10, target2 is inconsistent with UE-B in spatial direction.
[0184] In one example, the communication resources and the perception resources are the same, and its schematic diagram can refer to the aforementioned Figure 11. At this time, referring to the aforementioned situation where the communication object and the perception object are consistent in the spatial direction, the perception resources include but are not limited to: AGC or GAP time slot resources for sending data on the communication beam, periodic SSB, PSSCH signals, PSCCH signals, DMRS information, CSI-RS, etc. These resources can be periodic (such as SSB or periodic side data information) or non-periodic (such as non-periodic accompanying data). It can also be a combination of various non-periodic data of accompanying data (such as CSI-RS and DMRS, etc.), a combination of periodic data, and a combination of non-periodic and periodic data, etc., and its combined resources can also be periodic or non-periodic.
[0185] Since the communication object and the perception object are inconsistent in the spatial direction, the fusion of the communication beam and the perception beam can be achieved through the spatial division method in the beam domain, that is, the communication beam and the perception beam are different.
[0186] In another example, the communication resources and the sensing resources are different, and the communication beam and the sensing beam can be the same or different. This example can refer to the relevant description of the second example in the scenario where the communication object and the sensing object are aligned in spatial direction, and the embodiments of this application are not repeated here.
[0187] In this embodiment, when the time domain resources in the communication resources and the sensing resources are the same, and the communication beams and the sensing beams are different, power can also be allocated to the different sensing beams and communication beams to reduce leakage interference between the different beams. The specific power allocation process can be referred to the relevant description of the scenario where the communication object and the sensing object are aligned in the spatial direction, and this embodiment of the application is not further described here.
[0188] Example 2: UE-A sends and UE-B receives a perception mode, UE-A is used to execute the communication method provided in the embodiment of the present application
[0189] Please refer to Figure 16, which is a schematic diagram of another perception mode provided by an embodiment of the present application. UE-A is the TX for communication signals and perception signals, and UE-B is the RX for communication signals and perception signals. There are objects to be perceived in both the communication direction and the non-communication direction, and Figure 16 shows target 3 to target 5. For the two cases where the communication object and the perception object are consistent and inconsistent in spatial direction, the embodiment of the present application has different allocations of time-frequency resources and beam resources. The following describes the two cases under the perception mode of Example 2.
[0190] 1. The communication object and the perception object are consistent in the spatial direction: As shown in FIG16 , the perception object (eg, target 5) within the range of the beam represented by the shadow is consistent with the communication object UE-B in the spatial direction.
[0191] In one example, the first transmission block and the second transmission block are the same transmission block, which can be used for communication and / or perception, and is a synaesthesia integrated transmission block. At this time, the communication resources and the perception resources are the same, and the communication beam and the perception beam are the same. It can be understood that there is no difference between communication and perception in terms of time-frequency resources and beam resources. The time-frequency and spatial resources of the two are integrated, and UE-A multiplexes periodic or non-periodic communication signals for perception. Communication resources and perception resources can refer to Figure 11 above, and the embodiments of the present application will not be described in detail here.
[0192] At this time, the sensing resources include but are not limited to: AGC or GAP time slot resources for sending data on the communication beam, periodic SSB, PSSCH signals, PSCCH signals, DMRS information, CSI-RS, etc. These resources can be periodic (such as SSB or periodic sidelink data information) or non-periodic (such as non-periodic sidelink data). It can also be a combination of various non-periodic data of sidelink data (such as CSI-RS and DMRS, etc.), and / or a combination of periodic data, and / or a combination of non-periodic and periodic data, etc., and its combined resources can also be periodic and / or non-periodic.
[0193] For example, when the first / second transport block is retransmitted multiple times, the beams indicated by the sensing beam indication information of the retransmitted first / second transport blocks may or may not contain the same beams. This allows different sensing beams to be indicated in different transmission symbols or time slots by utilizing the communication retransmission mechanism, thereby improving sensing accuracy while ensuring communication performance. The improved sensing accuracy relies on the different frequency resources of the retransmissions, which is equivalent to increasing bandwidth.
[0194] Please refer to Figure 17, which is a schematic diagram of a sensing beam indication provided by an embodiment of the present application. As shown in Figure 17, in the first transmission opportunity of the PSSCH, the sensing beam indication information in the SCI indicates beam 1, that is, the first transport block is sent via beam 1. In the second transmission opportunity of the PSSCH, the sensing beam indication information in the SCI indicates beam 2, that is, the first transport block is sent via beam 2. In the third transmission opportunity of the PSSCH, the sensing beam indication information in the SCI indicates beam 3, that is, the first transport block is sent via beam 3.
[0195] In another example, the first transmission block and the second transmission block are not the same transmission block, and the communication resources and the perception resources are different, for example, the communication resources and the perception resources are orthogonal. The communication resources and the perception resources can refer to Figure 12 above, and the embodiments of the present application are not described here. Since the communication resources and the perception resources are independent of each other, the communication and perception processes are interference-free, and the communication beam and the perception beam can be the same or different. When the communication beam and the perception beam are the same, the fusion of the communication beam and the perception beam can be achieved by time division (that is, different time domain resources).
[0196] In this embodiment, when the time domain resources in the communication resources and the sensing resources are the same, and the communication beams and the sensing beams are different, power can be allocated to the different sensing beams and communication beams to reduce leakage interference between the different beams. The specific power allocation process can be referred to the relevant description of the scenario in which the communication object and the sensing object are aligned in the spatial direction in the aforementioned embodiment 1, and is not further described in this embodiment of the present application.
[0197] In this example, the transmission of the communication signal can be periodic or non-periodic, and the transmission of the perception signal can be periodic or non-periodic, which is not limited in this embodiment of the present application. For details of this example, please refer to the description of the second example in the scenario where the communication object and the perception object are consistent in spatial direction in the aforementioned embodiment 1. This embodiment of the present application will not be repeated here.
[0198] 2. The communication object and the perception object are inconsistent in spatial direction: As shown in Figure 16, target3 and target4 are inconsistent with UE-B in spatial direction.
[0199] The communication object and the perception object are inconsistent in spatial direction. The perception service can be regarded as a service independent of the communication service. The perception resources can be allocated and the perception beams can be indicated based on the perception service.
[0200] For example, UE-A may also determine a candidate sensing beam set, where the candidate sensing beam set includes at least one candidate sensing beam. The first transmission block also includes candidate sensing beam indication information, where the candidate sensing beam indication information is used to indicate the candidate sensing beam set. In this way, the receiving end can determine the sensing receiving beam in advance based on the candidate sensing beam set indicated by the candidate sensing beam indication information, thereby performing the corresponding sensing process. UE-A may determine a sensing candidate beam set (i.e., a candidate sensing beam set) based on a beam feedback process between two UEs of a UE pair in the communication system.
[0201] Please refer to Figure 18, which is a schematic diagram of determining a candidate perception beam set provided by an embodiment of the present application. Figure 18 shows UE-A, UE-B and UE-C, as well as beams 1 to 4. Based on the beam management process of communication with UE-B and UE-C, UE-A determines the beam used to send the synaesthesia transmission block and the perception beam used to send the first transmission block. For example, beam 2 and beam 4 are determined as ISAC beams for sending the synaesthesia transmission block, and beam 1 and beam 3 are determined as perception beams. The UE-A side maintains a candidate perception beam set {beam 1, beam 3}. The first transmission block also includes candidate perception beam indication information for indicating {beam 1, beam 3}.
[0202] In one example, the communication resources and the perception resources are the same, and its schematic diagram can refer to the aforementioned Figure 11, and the embodiments of the present application will not be described in detail here. At this time, referring to the aforementioned situation where the communication object and the perception object are consistent in the spatial direction, the perception resources include but are not limited to: AGC or GAP time slot resources for sending data on the communication beam, periodic SSB, PSSCH signals, PSCCH signals, DMRS information, CSI-RS, etc. sent along the channel. These resources can be periodic (such as SSB or periodic side data information) or non-periodic (such as non-periodic along-channel data). It can also be a combination of resources of various non-periodic data (such as CSI-RS and DMRS, etc.) of along-channel data, and / or a combination of resources of periodic data, and / or a combination of resources of non-periodic and periodic data, etc., and its combined resources can also be periodic and / or non-periodic.
[0203] Since the communication object and the perception object are inconsistent in the spatial direction, the fusion of the communication beam and the perception beam can be achieved through the spatial division method in the beam domain, that is, the communication beam and the perception beam are different.
[0204] In another example, the communication resources and the sensing resources are different, and the communication beam and the sensing beam can be the same or different. This example can refer to the description of the second example in the scenario where the communication object and the sensing object are aligned in spatial direction in the aforementioned embodiment 1, and is not further described in this embodiment of the present application.
[0205] In this embodiment, when the time domain resources in the communication resources and the sensing resources are the same, and the communication beams and the sensing beams are different, power can also be allocated to the different sensing beams and communication beams to reduce leakage interference between the different beams. The specific power allocation process can be referred to the relevant description of the scenario in which the communication object and the sensing object are aligned in the spatial direction in the aforementioned embodiment 1, and this embodiment of the present application will not be repeated here.
[0206] Please refer to FIG. 19 , which is a flow chart of another communication method provided in an embodiment of the present application. FIG. 19 illustrates the method by applying it to a network device as an example. The method may include the following steps:
[0207] 401. Determine sensing resources, communication resources, a sensing beam, and a communication beam. The sensing beam is used to send a sensing signal, and the communication beam is used to send a communication signal.
[0208] 402. On the perception beam, a first transmission block is sent through the perception resource, where the first transmission block includes DCI, and the DCI carries perception beam indication information, or the first transmission block is an SSB, and the SSB carries perception beam indication information, where the perception beam indication information indicates that the transmission beam of the first transmission block is the perception beam.
[0209] 403. Send a second transmission block on the communication beam through the communication resource, where the second transmission block is used for communication.
[0210] The implementation process of processes 401 to 403 can refer to the aforementioned processes 301 to 303, and the allocation of communication resources, perception resources, communication beams and perception beams can also refer to the aforementioned embodiments 1 and 2. The embodiments of this application will not be repeated here.
[0211] In summary, the communication method provided in the embodiment of the present application first determines the perception resources, communication resources, perception beams and communication beams, the perception beams are used to send perception signals, and the communication beams are used to send communication signals, and then the first transmission block is sent on the perception beam through the perception resources, and the second transmission block is sent on the communication beam through the communication resources, the second transmission block is used for communication, the first transmission block includes perception beam indication information, the perception beam indication information indicates that the transmission beam of the first transmission block is the perception beam, after the communication resources and communication beams are allocated to the transmission blocks used for communication, and the perception resources and perception beams are allocated to the transmission blocks used for perception, by adding the perception beam indication information to the transmission blocks used for perception, the receiving end is instructed to perform perception processing on the transmission blocks sent on the beams indicated by the perception beam indication information, thereby realizing the effective fusion of the communication beam and the perception beam in the synaesthesia integration scenario.
[0212] Furthermore, in the embodiment of the present application, in the perception mode where the transmitting end transmits and receives independently or the transmitting end transmits and the receiving end receives, the communication resources and the perception resources can be designed to be the same or different for the two situations where the spatial directions of the communication object and the perception object are consistent or inconsistent. When the communication resources and the perception resources are the same, the communication beam and the perception beam can be the same; when the communication resources and the perception resources are different, the communication beam and the perception beam can be the same or different, thereby achieving effective fusion of the communication beam and the perception beam. In addition, when the time domain resources in the communication resources and the perception resources are the same, and the communication beam and the perception beam are different, power can be allocated to different perception beams and communication beams to reduce leakage interference between different beams.
