Description

[0001] This application is a divisional application of invention application No. 201911154613.X, filed on November 22, 2019, entitled "Communication Method and Apparatus". Technical Field

[0002] This application relates to communication technology, and more particularly to a communication method and apparatus. Background Technology

[0003] In the field of communications, the transmitting and receiving ends typically communicate using antennas. To meet the increasingly demanding communication requirements of users, multiple antennas are usually installed in both the transmitting and receiving ends, and communication is achieved through these multiple antennas.

[0004] In existing technologies, communication processes based on multiple antennas typically involve the transmitting end selecting a transmitting antenna for data transmission and the receiving end selecting a receiving antenna for data reception. For example, taking a terminal device sending data to a base station with two transmitting antennas, the antenna selection process mainly includes two stages: uplink measurement and downlink control. In the uplink measurement stage, the terminal device uses different antennas on different time-frequency resources to transmit sounding reference signals (SRS). The base station uses the received SRS to estimate the channel quality of the two antennas of the terminal device and selects the transmitting antenna with the better channel quality. In the downlink control stage, the base station implicitly includes the antenna selection result in the uplink scheduling control information sent to the terminal device. The terminal device then performs blind detection on the uplink scheduling control information to obtain the base station's antenna selection result and selects a suitable transmitting antenna based on this result.

[0005] However, with the increasing number of antennas in the transmitting and receiving ends, especially when both the transmitting and receiving ends use panels with antenna arrays consisting of several antennas for communication, the existing technology requires all antenna ports in each panel to be allocated a time-frequency resource to transmit SRS, resulting in high resource overhead. Summary of the Invention

[0006] This application provides a communication method and apparatus to solve the technical problem of high resource overhead in multi-antenna communication in the prior art.

[0007] In a first aspect, embodiments of this application provide a communication method, including:

[0008] The second electronic device receives K panel reference signals from the first electronic device through N panels; wherein, the panel reference signals are associated with the identifiers of the panels in the first electronic device that transmit the panel reference signals; N and K are both integers greater than or equal to 2; the second electronic device measures the signal quality of the K panel reference signals. That is, using panels as the basic selection unit in communication eliminates the need to allocate reference signal resources for each antenna interface in multi-antenna communication, thus reducing resource overhead. Specifically, the first electronic device can send K panel reference signals to the second electronic device through panels, and the panel reference signals are associated with the identifiers of the panels in the first electronic device that transmit the panel reference signals. After receiving the K panel reference signals through N panels, the second electronic device can measure the signal quality of the received K panel reference signals. Furthermore, based on the measurement results, it can select a first panel for receiving data transmitted by the first electronic device and / or for transmitting data to the first electronic device, thereby achieving communication with the first electronic device. In other words, in this embodiment, instead of using antennas as the basic selection unit as in the prior art, a panel consisting of an antenna array containing several antennas is used as the basic selection unit in communication, which eliminates the need to allocate reference signal resources for each antenna interface in multi-antenna communication, thus reducing resource overhead.

[0009] In one possible design, the second electronic device further includes: the second electronic device sending first indication information to the first electronic device using the first panel; the first panel is related to the signal quality of K panel reference signals, and the first indication information is indication information related to one or more panels of the first electronic device. In this way, when the first electronic device needs to send data to the second electronic device, it can determine the panel to which the data should be sent based on the first indication information. Furthermore, during this process, the first electronic device does not need to measure the signal quality between each panel of the first electronic device and each panel of the second electronic device, thereby saving the computing resources of the first electronic device.

[0010] In one possible design, the panel reference signal includes one or more of the following signals: a first panel reference signal, the initial value of which is a pseudo-random sequence associated with the identifier of the panel transmitting the panel reference signal; a second panel reference signal, the second panel reference signal associated with at least one of the following: the identifier of the panel transmitting the panel reference signal, or the initial value of a pseudo-random sequence of a physical layer-side walkway control channel demodulation reference signal PSCCH DMRS; a third panel reference signal, the third panel reference signal associated with at least one of the following: the identifier of the panel transmitting the panel reference signal, or the initial value of a pseudo-random sequence of a physical layer-side walkway broadcast channel demodulation reference signal PSBCH DMRS; and a fourth panel reference signal, the fourth panel reference signal associated with at least one of the following: the identifier of the panel transmitting the panel reference signal, or the initial value of a pseudo-random sequence of a physical layer-side walkway channel state information reference signal SL-CSI-RS.

Because the first indication information includes the panel identifiers of the second electronic device, the first electronic device can understand the status of the second electronic device.

[0017] In one possible design, the second electronic device receives K panel reference signals from the first electronic device through N panels, including: the second electronic device receives K panel reference signals from the first electronic device through N panels in multiple time units; since the panel reference signals in the second electronic device are received in a time-division manner, interference between the panel reference signals sent between the panels can be avoided, thereby enabling the second electronic device to obtain more accurate measurement results when measuring signal quality.

[0018] Alternatively, the second electronic device receives K panel reference signals from the first electronic device through N panels in one time unit.

[0075] The method described in this application can be applied to long term evolution (LTE) systems, 5G systems, or future mobile communication systems.

[0076] The first electronic device and the second electronic device described in the embodiments of this application can both be terminal devices, network devices, vehicles or other electronic devices, or chip systems, circuits or modules in vehicles or other electronic devices, etc., and this application does not impose any limitations. It should be noted that, for the sake of consistency, the embodiments provided in this application are described using the first electronic device and the second electronic device as examples.

[0077] In this embodiment of the application, when the first electronic device is a network device and the second electronic device is a terminal device; or when the first electronic device is a terminal device and the second electronic device is a network device; or when both the first and second electronic devices are network devices, the first and second electronic devices can communicate based on a network system. For example, the network system can be: a 5G communication system, an LTE communication system, a UMTS terrestrial radioaccess network (UTRAN) system, or a GSM / EDGE radio access network (GERAN) architecture. Alternatively, it could be a public land mobile network (PLMN) system, a 6G system, or a subsequent communication system, etc. This embodiment of the application does not limit the specific implementation of such systems.

[0078] The terminal equipment may include multiple panels. The terminal equipment can refer to industrial robots, industrial automation equipment, user equipment (UE), access terminals, user units, user stations, mobile stations, mobile stations, remote stations, remote terminals, mobile devices, user terminals, terminals, wireless terminal equipment, user agents, or user devices. For example, the terminal equipment can be a cellular phone, cordless phone, session initiation protocol (SIP) phone, wireless local loop (WLL) station, personal digital assistant (PDA), handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, in-vehicle equipment, wearable device, terminal equipment in a 5G network or a network after 5G, or terminal equipment in a future evolved public land mobile network (PLMN). This application does not limit the scope of the application.

[0079] The network device can have multiple panels and can be used to communicate with terminal devices. For example, the network device can be a 5G new radio access technology (NR) base station (gNodeB, gNB), a long term evolution (LTE) base station (eNB), a base station (NodeB, NB) in a wideband code division multiple access (WCDMA) system, a base transceiver station (BTS) in a GSM or CDMA system, a relay station, an access point, vehicle-mounted equipment, wearable devices, and network-side equipment in networks after 5G, or network equipment in future evolved PLMN networks, roadside site units (RSUs), relay nodes with base station resource allocation functions, or terminals with resource allocation functions, etc. This application does not impose any restrictions on these aspects.

[0080] The first and second electronic devices in this application embodiment can also communicate based on a vehicle-to-everything (V2X) system. In the sidelink (SL) communication of the V2X system, a second frequency range (FR2) can be applied to enable the deployment and application of frequency bands above 6 GHz, providing support for functions such as vehicle platooning, extended sensors, and autonomous driving. Alternatively, frequency bands below 6 GHz can also be used in the SL communication of the V2X system; this application embodiment does not specifically limit this approach.

[0081] For example, V2X can include four parts: vehicle-to-network (V2N), vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), and vehicle-to-pedestrian (V2P). The main function of V2X is to enable vehicles to connect to cloud servers via mobile networks, thereby using applications such as navigation, entertainment, and anti-theft provided by the cloud servers. V2V can be used for information exchange and alerts between vehicles, such as for collision avoidance warnings. V2I can be used for communication between vehicles and road infrastructure (such as traffic lights and roadblocks) to obtain road management information such as traffic light signal timing. V2P can be used for vehicles to provide safety warnings to pedestrians or non-motorized vehicles on the road.

[0082] The first electronic device can be configured with multiple panels, which can also be called arrays, antenna panels, etc. A panel refers to an antenna array composed of several antennas, and the panel is generally directional.

[0083] Multiple panels can have different orientations. For example, the number of panels can be determined by (M... g N g ) indicates that M g N represents the number of panels in the vertical dimension. g This indicates the number of panels in the horizontal dimension. A single panel is numbered (m...). g ,n g ) indicates that 0 ≤ m g <M g , 0≤n g <N g .

[0084] The antenna configuration on a single panel is represented by (M, N, P), where M represents the number of antennas in the vertical dimension on a single panel, N represents the number of antennas in the horizontal dimension on a single panel, and P represents the number of antenna polarizations.

[0085] Panel (m) g ,n g The orientation of (Ω) is determined by (Ω) mg,ng ,Θ mg,ng ) indicates that Ω mg,ng Representing the azimuth angle, it characterizes the horizontal pointing angle of the panel, Θ mg,ng The tilt angle represents the vertical orientation angle of the panel.

[0086] It is understandable that when the first electronic device is applied to a multiple input multiple output (MIMO) system, the multi-panel setup is beneficial to improving the configuration flexibility of the MIMO system.

[0087] The first electronic device can have various panel configuration methods, for example, such as Figure 1 The diagram illustrates a possible panel configuration (which can be referred to as Configuration 1) when the first electronic device is a vehicle. Four panels are mounted on the roof, and each panel may contain four dual-polarized antennas. Specific parameters could be: (M, N, P, M...) g N g )=(1,4,2,1,4), Ω 0,1 =Ω 0,0 +90°, Ω 0,2 =Ω 0,0 +180°, Ω 0,3 =Ω 0,0 +270°, Θ 0,0 =Θ 0,1=Θ 0,2 =Θ 0,3 =90°. The vehicle can transmit signals using a wide beam in all four horizontal directions or receive signals using a wide-angle spatial filter.

[0088] For example, such as Figure 2 This illustrates another possible panel configuration (which can be called configuration two) when the first electronic device is a vehicle. Two panels are mounted on the front and rear bumpers of the vehicle, respectively. Each panel can contain eight dual-polarized antennas, with specific parameters including (M, N, P, M). g N g )=(2,4,2,1,2), Ω 0,0 =0°, Ω 0,1 =180°, Θ 0,0 =Θ 0,1 =90°. The vehicle can use a wide beam for signal transmission or a wide-angle spatial filter for signal reception in both the front and rear horizontal directions.

[0089] In practical applications, because the antenna on the panel is a directional antenna, the panel is directional in both the vertical and horizontal dimensions. If the vehicle selects an inappropriate panel when transmitting signals, the transmitted signal may not be directed to the receiver, or the receiver's spatial filter may not be able to cover the signal transmitted by the vehicle, or the signal transmitted by the vehicle may experience additional path loss or penetration loss, resulting in a mismatch between the transmitting and receiving ends and a decrease in channel gain and signal-to-noise ratio.

[0090] The specific panel configuration of the second electronic device can be referred to the panel configuration description of the first electronic device. The panel configuration of the second electronic device may be different from or the same as that of the first electronic device, and will not be elaborated here.

[0091] This is understandable, as both the first and second electronic devices may include 32 single-polarized antennas. If the antennas are used as selection targets during communication between the first and second electronic devices, time-domain resources need to be allocated to transmit sidelink sounding reference signals (SL-SRS) for each antenna port of either the first or second electronic device, resulting in significant resource overhead. Furthermore, the link quality of different antenna ports is primarily affected by small-scale fading in the channel. Rapid changes in small-scale fading require high-frequency channel measurements for antenna selection. However, when both the first and second electronic devices are vehicles, the link quality during communication between different panels in the FR2 band of V2X SL is mainly affected by the relative positions of the vehicles and the presence of obstacles between them. Since the relative positions and obstacles between vehicles change relatively slowly, low-frequency channel measurements may be necessary. Therefore, using antennas as selection targets is not suitable for communication scenarios between the first and second electronic devices.

[0092] In this embodiment of the application, a communication method is proposed that uses the panels in the first electronic device and the panels in the second electronic device as selection objects. This allows the first electronic device or the second electronic device to perform signal quality measurement, sending panel selection or receiving panel selection as basic units when communicating, without needing to allocate reference signal resources for each antenna interface, thus reducing resource overhead.

[0093] When using a panel as the selection object, the technical aspects that may be involved include:

[0094] Panel determination: refers to the process by which the sender or receiver determines which sending panel or receiving panel should be selected.

[0095] Panel measurement: refers to the process by which the receiver measures a reference signal sent by the transmitter that is related to panel selection.

[0096] Panel measurement: refers to the process by which the receiver reports the panel measurement results to the sender.

[0097] Panel sweeping refers to the process in which the sender selects a panel in sequence to send data, and the receiver selects a panel in sequence to receive data.

[0098] Panel correspondence allows the receiver to determine its sending panel based on the selected receiving panel, and the sender to determine its receiving panel based on the selected sending panel. For example, in V2X SL, panel correspondence intuitively means that the receiving panel of the destination vehicle UE can act as a sending panel to transmit information (such as reporting information) to the source vehicle UE, and the sending panel of the source vehicle UE can act as a receiving panel to receive information transmitted by the destination vehicle UE. Panel correspondence eliminates the need for repeated panel selection when the receiver transmits information to the sender.

[0099] The above technical points will be explained in detail in subsequent embodiments, and will not be repeated here.

[0100] It should be noted that although beam management may involve processes such as beam determination, beam measurement, beam reporting, and beam scanning, beam management is mainly geared towards large-scale MIMO systems. In current V2X SL communication, the number of antennas on a single array of the vehicle UE is limited, making it impossible to form a narrow beam with obvious directionality. Therefore, beam management cannot be obviously used in the panel-based communication method of this application embodiment.

[0101] The method described in this application can be applied to unicast, multicast, and broadcast application scenarios. Subsequent embodiments will be illustrated using the example where both the first and second electronic devices are vehicles.

[0102] For example, Figures 3 to 5 Three possible system architecture diagrams of embodiments of this application are shown.

[0103] Figure 3 A schematic diagram of the system architecture of the method according to an embodiment of this application in a unicast application scenario is shown. Figure 3 As shown, in a unicast scenario, there can be a source vehicle UE and a destination vehicle UE. The source vehicle UE can act as an information sending entity in V2X SL, and the destination vehicle UE can act as an information receiving entity in V2X SL. The destination vehicle UE can also measure the quality of the signal received from the source vehicle UE and can send the measurement results back to the source vehicle UE.

[0104] The source vehicle UE can transmit a beam to the destination vehicle UE. The transmitted beam can be a directional radiation pattern from the same antenna port on a panel of the source vehicle UE. The received beam can be a directional spatially filtered pattern from the same antenna port on the receiving panel of the destination vehicle UE. Figure 3 Only the transmitted beam is marked, represented by a petal shape.

[0105] Figure 4A schematic diagram of the system architecture of the method according to an embodiment of this application in a multicast application scenario is shown. Figure 4 As shown, in a multicast scenario, there can be one source vehicle UE and a group of destination vehicle UEs.

[0106] The source vehicle UE can send beams to a group of destination vehicle UEs. The number of destination vehicle UEs can be set according to the actual application scenario, and this application embodiment does not specifically limit this.

[0107] Figure 5 A schematic diagram of the system architecture of the method according to an embodiment of this application in a broadcast application scenario is shown. Figure 5 As shown, in a broadcast scenario, there can be a source vehicle UE, without distinguishing the destination vehicle UE.

[0108] The source vehicle UE can broadcast signals using multiple panels, and the destination vehicle UE can be a vehicle that can receive the broadcast signals from the source vehicle UE.

[0109] Taking a first electronic device as the source vehicle UE and a second electronic device as the destination vehicle UE as an example, the technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be implemented independently or in combination with each other. The same or similar concepts or processes may not be described again in some embodiments.

[0110] Figure 6 This is a flowchart illustrating a communication method provided in an embodiment of this application, such as... Figure 6 As shown, the method includes:

[0111] S601: The second electronic device receives K panel reference signals from the first electronic device through N panels; wherein, the panel reference signals are related to the identifiers of the panels in the first electronic device that transmit the panel reference signals; N and K are both integers greater than or equal to 2.

[0112] S602: The second electronic device measures the signal quality of K panel reference signals.

[0113] In this embodiment of the application, the first electronic device can send K panel reference signals to the second electronic device through M panels, and the second electronic device can receive K panel reference signals from the first electronic device through N panels.

[0114] The panel reference signal in this application embodiment is a signal related to the identifier of the panel that sends the panel reference signal. The specific form of the panel reference signal can be a pseudo-random sequence, such as a gold sequence. The identifier of the panel can be set according to the actual application scenario, and this application embodiment does not specifically limit it.

[0115] After receiving K panel reference signals from the first electronic device using N panels, the second electronic device can measure the signal quality of the received K panel reference signals. For example, it can measure the reference signal received power (RSRP) of each panel reference signal.

[0116] Optionally, the measurement result obtained from measuring the signal quality of the reference signal of panel K can be used to determine the first panel for receiving data transmitted by the first electronic device from among N panels. This first panel can also be used by the second electronic device to transmit data to the first electronic device. That is, in this embodiment, instead of selecting the unit based on the antenna as in the prior art, the basic selection unit in communication is a panel consisting of an antenna array containing several antennas. This eliminates the need to allocate reference signal resources for each antenna interface in multi-antenna communication, thus reducing resource overhead.

[0117] Optionally, the second electronic device may use the first panel to send first instruction information to the first electronic device; the first instruction information is instruction information related to one or more panels of the first electronic device.

[0118] In this embodiment, after the second electronic device obtains the measurement result by measuring the signal quality of the K panel reference signal, it can determine that the signal quality is better when one or more panels of the first electronic device send the panel reference signal. Therefore, the second electronic device can use the first panel to send the identifier of one or more panels of the first electronic device that have better signal quality when sending the panel reference signal to the first electronic device, or send the measurement result to the first electronic device. When the first electronic device needs to send data to the second electronic device, it can determine the panel to send data to the second electronic device according to the first indication information. In this process, the first electronic device does not need to measure the signal quality between each panel of the first electronic device and each panel of the second electronic device, thereby saving the computing resources of the first electronic device.

[0119] For example, Figure 7 The diagram illustrates the signaling flow of a communication method in a unicast scenario according to an embodiment of this application.

[0120] S701: The first electronic device acquires M panel reference signals; the panel reference signals are related to the identifier of the panel of the first electronic device; M is an integer greater than or equal to 2.

[0121] In this embodiment of the application, the first electronic device may include M panels, each panel may correspond to a panel reference signal, and the panel reference signal is a signal related to the identification of the panel of the first electronic device, so that communication can be realized based on the panel reference signal with the panel as the selection unit.

[0122] The first electronic device can generate M panel reference signals based on the identifiers of the M panels.

[0123] The first electronic device can also obtain M panel reference signals according to the provisions of the protocol.

[0124] The first electronic device may also obtain M panel reference signals from network devices or other devices, and this application embodiment does not specifically limit this.

[0125] In this embodiment, the panel identifiers can be configured according to protocols or actual application scenarios. For example, the panel identifier can be a number. In the first panel configuration described above, the panel facing the same direction as the vehicle can be numbered 0, and the other three panels can be numbered 1, 2, and 3 in clockwise or counterclockwise directions respectively. Alternatively, the four panels in the vehicle can be arbitrarily numbered 0, 1, 2, and 3, or any other numbering can be used. This embodiment does not limit this. In the second panel configuration described above, two panels in the vehicle can be numbered differently from those in the first configuration, such as 4 and 5, so that a specific panel can be identified by its number.

[0126] Or, the panel's identifier i panel_ID It can be calculated from the number and the identifier of the panel configuration in the first electronic device. For example, using n config One feasible method to represent the array configuration itself is: configure a corresponding n config =0, configuration two corresponds to n config =1. Use universal array numbering (m g ,n g The horizontal array number n in ) g Each battlefront is numbered. One feasible approach is to assign n to the battlefront facing the same direction as the vehicle in configuration one. g =0, and the others are numbered n in clockwise direction. g =1, n g =2 and n g =3. In configuration two, the array face with the same orientation as the vehicle is numbered n. g =0, the other array is numbered n g =1. Using n config and n g Calculate array surface identifier i panel_ID For the multiple arrays in Configuration 1 and Configuration 2, a feasible array identification method is i panel_ID =2 2 n config +n g Combined with the aforementioned n config and ng In the representation method, the array surface identifier in configuration one is i. panel_ID =0,1,2,3, the two array face identifiers in configuration two are i panel_ID =4,5.

[0127] It is understood that the panel markings may also be represented in other ways depending on the actual application scenario, and this application embodiment does not specifically limit this.

[0128] The panel reference signal in this application embodiment may include various forms. This application embodiment uses a first panel reference signal as an example for illustration.

[0129] In one possible implementation, the initial value of the pseudo-random sequence of the first panel reference signal is related to the identifier of the panel that transmits the panel reference signal.

[0130] The first panel reference signal can be defined as a Panel Specific Reference Signal (PS-RS), or it can be defined as a signal with other names. Taking PS-RS as an example, PS-RS is a reference signal used to characterize the source array of the signal and contains the array's identification information. The generation process of PS-RS is affected by the configuration and numbering of its corresponding panel.

[0131] Optionally, the initial value C1 of the pseudo-random sequence of PS-RS init Satisfying the formula:

[0132] C1 init =2 11 (i panel_ID +1)+2 6 (i panel_ID +1)

[0133] S702: The first electronic device sends K panel reference signals to the second electronic device through M panels; wherein, the first electronic device sends one or more panel reference signals on any one of the M panels; K is an integer greater than or equal to M.

[0134] S703: The second electronic device receives K panel reference signals from the first electronic device through N panels.

[0135] In this embodiment of the application, each panel of the first electronic device can send a panel reference signal corresponding to the panel, and each panel can send one or more panel reference signals corresponding to the panel. Therefore, K can be an integer greater than or equal to M.

[0136] In this embodiment, taking the panel reference signal PS-RS as an example, the PS-RS can be mapped to a single time unit (e.g., a time slot) with the Physical Sidelink Control Channel (PSCCH) or the Physical Sidelink Shared Channel (PSSCH) in a frequency-division multiplexing, time-division multiplexing, or both. When the panel of the first electronic device transmits the PS-RS, the Sidelink Control Information (SCI) can carry the presence indication information of the PS-RS and / or the resource mapping mode of the PS-RS. Optionally, in a unicast scenario, the SCI can also carry information indicating the time-frequency resources used by the second electronic device in subsequent reporting of measurement results.

[0137] In one optional implementation, the first electronic device sequentially transmits K panel reference signals to the second electronic device through M panels in multiple time units. For example, the first electronic device can sequentially select a panel to transmit time units containing PS-RS signals in a certain time order. Accordingly, the second electronic device can receive the K panel reference signals from the first electronic device through N panels in multiple time units. Because the panel reference signals in the first electronic device are transmitted in a time-division multiplexing manner, interference between the panel reference signals transmitted by different panels can be avoided, thereby enabling the second electronic device to obtain more accurate measurement results when subsequently measuring signal quality.

[0138] In another alternative implementation, the first electronic device transmits K panel reference signals to the second electronic device through M panels in one time unit. For example, the first electronic device can simultaneously transmit K panel reference signals to the second electronic device through M panels in one time unit; consequently, the second electronic device can receive the K panel reference signals from the first electronic device through N panels in one time unit. Because the first electronic device transmits panel reference signals to the second electronic device simultaneously through M panels, time resources for transmitting panel reference signals can be saved.

[0139] S704: The second electronic device measures the signal quality of K panel reference signals.

[0140] In this embodiment, the second electronic device can measure the RSRP of the received K panel reference signals. Therefore, the optimal receiving panel can be determined based on the measured RSRP of the K panel reference signals. This optimal receiving panel can also be the transmission array used by the second electronic device when sending information to the first electronic device. For example, the second electronic device obtains 8 RSRPs during one transmission array scan: P 4,0 P 5,0 P 4,1 P 5,1 P 4,2 P 5,2 P 4,3 P 5,3 The maximum value is P. 5,0 The second electronic device can then determine that array 5 is the optimal receiving array.

[0141] Optionally, the second electronic device can obtain the panel identifier of the panel reference signal corresponding to the panel in the first electronic device through blind detection, and then determine the start and end points of the panel scanning time of the first electronic device accordingly.

[0142] For example, suppose Indicated on the panel j of the second electronic device paneI_ID The first electronic device panel i measured on panel_ID The PS-RS transmits the RSRP. During the measurement process, the second electronic device blindly detects the i carried by a certain PS-RS. panel_ID After receiving the information, the start time, end time, and current scanning progress of the first electronic device's panel scanning are known, allowing the determination of the number of panels already scanned and those to be scanned. For example, taking panel 5 in the first electronic device as configuration one and panel 5 in the second electronic device as configuration two, the second electronic device uses the PS-RS received from panel 5 to blindly detect i... panel_ID When the result equals 0, a judgment is made: one transmitting panel has been scanned, and three more transmitting panels will be scanned. This allows the second electronic device to reserve resources for receiving panel reference signals from the first electronic device.

[0143] S705: The second electronic device sends first indication information to the first electronic device using the first panel; the first panel is related to the signal quality of K panel reference signals, and the first indication information is indication information related to one or more panels of the first electronic device.

[0144] In this embodiment of the application, the second electronic device can obtain the time-frequency resource indication used to send the first indication information from the SCI in the first electronic device. The first indication information can be set in the SCI and sent to the first electronic device in the corresponding time domain.

[0145] In this embodiment, the second electronic device can use the panel with the largest RSRP of the received reference signal as the first panel to send first indication information to the first electronic device. The first indication information may include one or more measurement results. Alternatively, it can use the panel with the second or third largest RSRP of the received reference signal as the first panel to send the first indication information to the first electronic device, etc. This embodiment does not specifically limit the method.

[0146] The first indication information may be associated with a panel of the first electronic device. For example, the first indication information may include the identifier of the panel in the first electronic device corresponding to the maximum RSRP, and / or, the maximum RSRP, on the one hand, because the first indication information contains less content, it can save signaling resources, and on the other hand, after receiving the first indication information, the first electronic device can directly use the panel corresponding to the panel identifier contained in the first indication information as the best panel for communication with the second electronic device.

[0147] The first indication information may also be related to multiple panels of the first electronic device. For example, the first information may include the identifiers of the panels corresponding to a large number of RSRPs in the first electronic device, and / or, where q can be a positive integer greater than or equal to 2. In this embodiment, because the maximum RSRP reflects the optimal communication array between the first and second electronic devices, the link corresponding to this maximum RSRP may fail due to changes in the positions of the first and second electronic devices. Therefore, by including multiple panel identifiers in the first indication information, the first electronic device can select the appropriate panel from among the multiple panels according to its needs, ensuring robustness of communication.

[0148] In one possible implementation, the first indication information includes one or more sets of panel information, each set of panel information including at least one of the following: an identifier of any panel of the first electronic device, an identifier of any panel of the second electronic device, or a measurement result of a reference signal corresponding to the set of panel information.

[0149] For example, Table 1 shows the possible contents of a first indication message. The transmitting array identifier may be an identifier of an array in a first electronic device, and the receiving array identifier may be an identifier of an array in a second electronic device.

[0150] Table 1

[0151]

[0152] In another possible implementation, the first indication information includes one or more panel information, each panel information including at least one of the following: an identifier of any panel of the first electronic device, and a measurement result of a reference signal corresponding to that panel.

[0153] For example, Table 2 shows the possible contents of a first indication message. The transmitting array identifier may be an identifier of an array in a first electronic device.

[0154] Table 2

[0155]

[0156] The difference between Table 2 and Table 1 is that Table 2 does not include the panel identifier of the second electronic device. Therefore, in the embodiment corresponding to Table 2, signaling resources can be saved. In contrast, Table 1 includes the panel identifier of the second electronic device, which allows the first electronic device to understand the status of the second electronic device.

[0157] For example, Figure 8 This diagram illustrates the beneficial effect of the destination vehicle UE reporting multiple sets of RSRPs and corresponding transmit and receive array identifiers to the source vehicle UE.

[0158] like Figure 8 As shown, both the source vehicle UE and the destination vehicle UE use configuration one, i.e., four panels are mounted on the roof of the vehicle. Both vehicles are moving eastward at speeds v and 2v, respectively. At time t0, the destination vehicle UE reports the RSRP of two array selection schemes, with the maximum RSRP being P. 3，1 Therefore, at time t0, the source vehicle UE selects 1 as the transmitting array and the destination vehicle UE selects 3 as the optimal receiving array. V2X SL is indicated by the line connecting the two. Since the destination vehicle UE is faster, transmitting array 1 gradually becomes unable to cover receiving array 3, therefore P 3,1 It will gradually decrease. Conversely, the P corresponding to the other set of array selection schemes... 2,0 The RSRP gradually increases. Based on the change in RSRP, the source vehicle UE predicts that its own transmitting array will switch to 0, and the destination vehicle UE's receiving array will switch to 2. At time t1, the link completes the switching between the transmitting and receiving arrays, and the maximum RSRP reported in the array report becomes P. 2,0 This is consistent with the prediction. Furthermore, since the array report provides both optimal and suboptimal array selection options, when the optimal array selection option encounters a link failure, the source vehicle UE is able to quickly attempt to restore link communication using the suboptimal array selection option.

[0159] For example, Figure 9 The diagram illustrates a unicast application scenario where the first electronic device is the source vehicle UE and the second electronic device is the destination vehicle UE.

[0160] The source vehicle UE can maintain panel identifiers (also known as array identifiers) and PS-RS (e.g., including PS-RS0, PS-RS1, PS-RS2, and PS-RS3), and perform array scanning, sequentially sending PS-RS0, PS-RS1, PS-RS2, and PS-RS3 to the destination vehicle UE. The destination vehicle UE can measure the RSRP of the received PS-RS signal while receiving the PS-RS, or it can measure the RSRP of the PS-RS signal after receiving all PS-RS0, PS-RS1, PS-RS2, and PS-RS3. This application embodiment does not limit this.

[0161] The destination vehicle UE can use the array corresponding to the largest RSRP as the optimal array and send the transmit array identifier and receive array identifier corresponding to the largest RSRP to the source vehicle UE. Alternatively, it can send the transmit array identifier and receive array identifier corresponding to multiple larger RSRPs to the source vehicle UE.

[0162] The source vehicle UE can determine the optimal array of the source vehicle UE based on the information sent by the destination vehicle UE, and then use the optimal array to send or receive data with the destination vehicle UE.

[0163] For example, Figure 10 This diagram illustrates the communication timing between a source vehicle UE and a destination vehicle UE according to an embodiment of this application. During the panel scanning step, the source vehicle UE can select different panels to transmit relevant reference signals in multiple time slots. If the source vehicle UE uses panel configuration one, it requires four time slots; if it uses panel configuration two, it requires two time slots. Simultaneously, the destination vehicle UE performs panel measurements and determines the receiving panel after the measurements are completed. Then, the destination vehicle UE uses one time slot to send reporting information to the source vehicle UE, and the source vehicle UE determines the transmitting panel based on the reporting information. After the transmitting panel is determined, the source vehicle UE uses that panel to send data information to the destination vehicle UE via PSSCH. The PS-RS transmission cycle in the diagram refers to the interval between two panel scans, representing the period for performing panel selection. Periodic panel selection is used to update the panel selection results. Alternatively, panel selection can be performed aperiodically, triggering the panel selection process again when the link fails.

[0164] In one possible implementation, Figure 7 The corresponding panel reference signal can be a second panel reference signal. This second panel reference signal is different from the first panel reference signal.

[0165] In one possible implementation, the second panel reference signal is associated with at least one of the following: the identifier of the panel that transmits the panel reference signal, or the initial value of a pseudo-random sequence of the Physical Sidelink Control Channel Demodulation Reference Signal (PSCCH DMRS).

[0166] In this embodiment, the second panel signal may be defined as PSCCH DMRS, but this PSCCH DMRS has a different meaning from the PSCCH DMRS in the historical protocol. The second panel signal may also be defined by other names, and this embodiment does not specifically limit it.

[0167] Optionally, the initial value C2 of the pseudo-random sequence of the second panel reference signal. init Satisfying the formula:

[0168] C2 init =(2 l C2 init，0 +i panel_ID )mod 2 31

[0169] Among them, C2 init，0 The initial value of the original pseudo-random sequence of PSCCH DMRS in the historical protocol can also be understood as the initial value of the pseudo-random sequence of PSCCH DMRS without considering panel selection. l is related to the total number of panel identifiers defined in the network. The total number of panel identifiers defined in the network can be the total number of all panel identifiers in the possible panel configurations in the network. For example, taking the total number of panel identifiers as 6 in the above embodiment, the value of l can be 3.

[0170] Since DMRS can be generated based on pseudo-random sequences, this embodiment modifies the initial value C2 of the pseudo-random sequence without affecting the functionality of DMRS or the accuracy of blind detection. init It is used to carry array identification, and because it gives PSCCH DMRS a new function, there is no need to allocate new reference signal resources, which can save signaling resources.

[0171] In one possible implementation, Figure 7 The corresponding panel reference signal can be a third panel reference signal. This third panel reference signal is different from the first panel reference signal.

[0172] In one possible implementation, the third panel reference signal is associated with at least one of the following: the identifier of the panel that transmits the panel reference signal, or the initial value of a pseudo-random sequence of the Physical Sidelink Broadcast Channel Demodulation Reference Signal (PSBCH DMRS).

[0173] In this embodiment, the third panel signal may be defined as PSBCH DMRS, but this PSBCH DMRS has a different meaning from the PSBCH DMRS in the historical protocol. The third panel signal may also be defined by other names, and this embodiment does not specifically limit it.

[0174] Optionally, the initial value C3 of the pseudo-random sequence of the third panel reference signal. init Satisfying the formula:

[0175] C3 init =(2 l C3 init，0 +i panel_ID )mod 2 31

[0176] Among them, C3 init，0 The initial value of the original pseudo-random sequence of PSBCH DMRS in the historical protocol can also be understood as the initial value of the pseudo-random sequence of PSBCH DMRS without considering panel selection. l is related to the total number of panel identifiers defined in the network. The total number of panel identifiers defined in the network can be the total number of all panel identifiers in the possible panel configurations in the network. For example, taking the total number of panel identifiers as 6 in the above embodiment, the value of l can be 3.

[0177] In this embodiment, the first electronic device can sequentially select a panel to transmit a Sidelink Synchronization Signal (SL-SSB), and the PSBCH in the SL-SSB carries the third panel reference signal. Because a new function is given to the PSBCH DMRS, there is no need to allocate new reference signal resources, which can save signaling resources.

[0178] In one possible implementation, Figure 7 The corresponding panel reference signal can be a fourth panel reference signal. This fourth panel reference signal is different from the first panel reference signal.

[0179] In one possible implementation, the fourth panel reference signal is associated with at least one of the following: the identifier of the panel that transmits the panel reference signal, or the initial value of a pseudo-random sequence of the Sidelink Channel State Information Reference Sign (SL-CSI-RS).

[0180] In this embodiment, the fourth panel signal may be defined as SL-CSI-RS, but this SL-CSI-RS has a different meaning from the SL-CSI-RS in the historical protocol. The fourth panel signal may also be defined by other names, and this embodiment does not specifically limit it.

[0181] Optionally, the initial value C4 of the pseudo-random sequence of the fourth panel reference signal. init Satisfying the formula:

[0182] C4 init =(2 l C4 init，0 +i panel_ID )mod 2 31

[0183] Among them, C4 init0 The initial value of the original pseudo-random sequence of SL-CSI-RS in the historical protocol can also be understood as the initial value of the pseudo-random sequence of SL-CSI-RS without considering panel selection. l is related to the total number of panel identifiers defined in the network. The total number of panel identifiers defined in the network can be the total number of all panel identifiers in the possible panel configurations in the network. For example, taking the total number of panel identifiers as 6 in the above embodiment, the value of l can be 3.

[0184] In this embodiment of the application, when the second electronic device sends the first indication information to the first electronic device, it can send PSSCH reporting information carrying the first indication information to the first electronic device on a designated time-frequency resource used for feedback SL-CSI-RS.

[0185] Since this application embodiment endows SL-CSI-RS with new functions, it does not require the allocation of new reference signal resources, thus saving signaling resources.

[0186] It should be noted that, in the C1 embodiment of this application... init C2 init C3 init and C4 init This is defined to distinguish the initial values ​​of the pseudo-random sequences from the first to the fourth reference signals. In application, a unified C might be used. init This application does not impose specific limitations on this aspect.

[0187] For example, when the communication method of this application embodiment is applied to a multicast scenario, unlike the embodiment corresponding to the unicast scenario, when the first electronic device sends K panel reference signals through M panels, each of the second electronic devices in a group of second electronic devices (which may include multiple second electronic devices) receives the K panel reference signals from the first electronic device through multiple panels, and respectively performs the step of measuring the signal quality of the K panel reference signals by the single second electronic device corresponding to the unicast scenario, and optionally, sending first indication information to the first electronic device. For details, please refer to the description of the embodiment corresponding to the unicast scenario, which will not be repeated here. Optionally, unlike the embodiment corresponding to the unicast scenario, the first electronic device may specify for each transmitting panel that the second electronic device reports the panel measurement results on a certain time-frequency resource after the transmitting panel scan is completed.

[0188] For example, Figure 11 A schematic diagram of the signaling flow of a communication method in a broadcast scenario according to an embodiment of this application is shown.

[0189] S1101: The first electronic device acquires a panel reference signal for broadcasting.

[0190] S1102: The first electronic device transmits the panel reference signal through M panels.

[0191] S1103: One or more second electronic devices measure the signal quality of the panel reference signal received by each panel.

[0192] In this embodiment, the panel reference signal used for broadcasting can be any one of the first to fourth panel signals described above. Optionally, the initial value of the pseudo-random sequence of the panel reference signal used for broadcasting is set to a special value; for example, in a PS-RS signal, C1 can be set. init The PS-RS signal obtained when all bits are 0 is used as panel reference information for broadcasting, or C1 can be set. init The PS-RS signal obtained when all bits are 1 is used as panel reference information for broadcasting, or a panel reference signal specifically for broadcasting can be set according to the actual application scenario. This application embodiment does not specifically limit this.

[0193] The panel reference signal used for broadcasting can be generated by the first electronic device or set in the protocol; this application embodiment does not specifically limit this.

[0194] A first electronic device can transmit a panel reference signal using M panels. One or more second electronic devices capable of receiving this panel reference signal can then measure the RSRP of the panel reference signal received by each of their own panels. Through blind detection, they determine that the panel reference signal transmitted by the first electronic device is for broadcasting. Each second electronic device can compare the RSRP of different panels to determine the optimal receiving panel, thus enabling data reception in broadcast application scenarios. Optionally, if a second electronic device has information to send to the first electronic device, the second electronic device can use the optimal receiving panel as the transmitting panel.

[0195] For example, Figure 12 This diagram illustrates another unicast application scenario where the first electronic device is the source vehicle UE and the second electronic device is the destination vehicle UE.

[0196] It should be noted that the panel identification method, panel reference signal measurement method, and panel determination method in this embodiment are different from those in the previous embodiment. Figures 6 to 9 The descriptions in the embodiments are similar and will not be repeated here. Similar to... Figures 6 to 9 Unlike the previous embodiment, this embodiment requires panel scanning, panel reporting, and acquisition of panel reference signals.

[0197] Specifically, in this embodiment, ① the source vehicle UE uses all panels to transmit signals simultaneously. The source vehicle UE can use all panels to broadcast any identical reference signal. Optional reference signals may include those in existing protocols such as PSCCH DMRS, PSSCH DMRS, SL-SSB, or SL-CSI-RS.

[0198] ② Destination vehicle UE panel measurement. The destination vehicle UE uses each receiver panel to measure the RSRP of a selected reference signal, for example, Panel j panel_ID RSRP measured above.

[0199] ③ Optimal Receiving Panel Determination for Destination Vehicle UE. The destination vehicle UE compares all RSRPs to determine the optimal receiving panel. Based on the panel correspondence property, this optimal receiving panel is also the transmitting panel that the destination vehicle UE should use to send information to the source vehicle UE. Figure 12 Taking the scenario setting as an example, the target vehicle UE receives two RSRPs: P4 and P5. The maximum value is P5, and the target vehicle UE determines that panel 5 is the best receiving panel based on this.

[0200] ④ The destination vehicle UE transmits a signal using the selected panel. Corresponding to the reference signal used by the source vehicle UE, the destination vehicle UE transmits the same reference signal using the receiving panel in step ③ based on the panel correspondence properties.

[0201] ⑤ Source vehicle UE panel measurement. The source vehicle UE uses each receiver panel to measure the RSRP of the selected reference signal. Indicates panel i panel_ID RSRP measured above.

[0202] ⑥ Source vehicle UE transmission panel determination. The source vehicle UE compares all RSRPs, determines the best receiving panel, and determines that the best receiving panel is also the best transmitting panel based on the panel's corresponding properties. Figure 12 Taking the scenario setting as an example, the source vehicle UE receives four RSRPs: P0, P1, P2, and P3. The maximum value is P0, and based on this, the source vehicle UE determines that panel 0 is the best receiving panel and also the best transmitting panel.

[0203] It is understandable that for V2X SL broadcast scenarios, only steps ①②③ of this embodiment are required.

[0204] In this embodiment, the source vehicle UE does not need to acquire the panel reference signal, and the destination vehicle UE does not need to report the signal measurement results to the source vehicle UE. Therefore, the time slot resources occupied by panel scanning can be saved, resulting in lower latency.
