[0048] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The step numbers in the following embodiments are only for ease of explanation and do not limit the order of the steps. The execution order of each step in the embodiments can be adapted according to the understanding of those skilled in the art.

[0049] For ease of understanding, the technical terms used in this application will be introduced below.

[0050] 1. Beam:

[0051] A beam is a directional signal transmission or reception effect created by the transmitter or receiver of a network or terminal device through an antenna array, similar to the beam of light from a flashlight focused in one direction. Using beams to transmit and receive signals can effectively increase the transmission distance.

[0052] The beam can be a wide beam, a narrow beam, or other types of beam. The beamforming technology can be beamforming technology or other technologies. Specifically, beamforming technology can be digital beamforming technology, analog beamforming technology, or hybrid digital / analog beamforming technology, etc.

[0053] Beams are generally associated with resources. For example, during beam measurement, network devices measure different beams using different resources, and the terminal devices provide feedback on the measured resource quality, allowing the network devices to determine the quality of the corresponding beam. During data transmission, beams can also be indicated by their corresponding resources. For instance, network devices use the Transmission Configuration Index (TCI) field in downlink control information (DCI) to indicate a transmission configuration indicator-state, and the terminal device determines the beam corresponding to that reference resource based on the reference resource contained in that TCI-state.

[0054] In communication protocols, beams can be specifically represented as digital beams, analog beams, spatial domain filters, spatial filters, spatial parameters, TCI, TCI-states, etc. Beams used for transmitting signals can be called transmission beams (or Tx beams), spatial domain transmission filters, spatial transmission filters, spatial domain transmission parameters, spatial transmission parameters, etc. Beams used for receiving signals can be called reception beams (or Rx beams), spatial domain reception filters, spatial reception filters, spatial domain reception parameters, spatial reception parameters, etc.

[0055] It is understood that the embodiments of this application uniformly use the term "beam" for description, but "beam" can be replaced by other equivalent concepts, and is not limited to the concepts mentioned above.

[0056] 2. Resources:

[0057] In communication protocols, reference signals are configured in the form of resources. Network devices will configure various reference signals to terminal devices in the form of resources. A resource is a configuration information unit, which usually includes parameters related to a reference signal, such as the time-frequency resource location of the reference signal, the number of ports, the time domain type (periodic / semi-static / aperiodic), etc.

[0058] Resources can be either uplink or downlink signal resources. Uplink signals include, but are not limited to, sounding reference signals (SRS) and demodulation reference signals (DMRS). Downlink signals include, but are not limited to, channel state information reference signals (CSI-RS), cell specific reference signals (CS-RS), user equipment specific reference signals (US-RS), demodulation reference signals (DMRS), and synchronization system / physical broadcast channel blocks (SS / PBCH blocks); among which, the SS / PBCH block can be abbreviated as synchronization signal block (SSB).

[0059] Resources can be configured via radio resource control (RRC) messages. Structurally, a resource is a data structure that includes relevant parameters for its corresponding uplink / downlink signal. These parameters include the type of uplink / downlink signal, the resource granularity carrying the uplink / downlink signal, the transmission time and period of the uplink / downlink signal, and the number of ports used to transmit the uplink / downlink signal. Each uplink / downlink signal resource has a unique identifier to identify that specific resource.

[0060] 3. Antenna panel:

[0061] Antenna panel can refer to the antenna panel of a network device or the antenna panel of a terminal device. An antenna panel typically has one or more antennas arranged in an antenna array to perform beamforming, thereby forming a simulated beam. The antenna array can generate simulated beams pointing in different directions. That is, multiple simulated beams can be formed on each antenna panel, and beam measurement can be used to determine which simulated beam is best for that antenna panel. In the embodiments of this application, unless otherwise specified, antenna panel refers to the antenna panel of the terminal device.

[0062] Antenna panels can be represented by a panel or a panel index, or they can be implicitly represented in other ways. For example, antenna panels can be characterized by antenna ports (such as CSI-RS ports, SRS ports, DMRS ports, phase-tracking reference signal (PTRS) ports, cell-specific reference signal (CRS) ports, tracking reference signal (TRS) ports, or SSB ports, etc.) or groups of antenna ports. They can also be characterized by resources (such as CSI-RS resources, SRS resources, DMRS resources, PTRS resources, CRS resources, TRS resources, SSB resources, etc.) or groups of resources. Alternatively, they can be characterized by a specific channel (such as physical uplink control channel (PUCCH), physical uplink sharing channel (PUSCH), physical random access channel (PRACH), PDSCH, physical downlink control channel (PDCCH), or physical broadcast channel (PBCH), etc.).

[0063] Terminal devices can be equipped with multiple antenna panels, which can be distributed in different locations and facing different directions. This ensures that no matter which direction the terminal device faces, at least one antenna panel will be facing the network device, enabling data transmission with the network device.

[0064] The technical solutions of this application embodiment can be applied to various communication systems, such as Wi-Fi wireless network systems, vehicle-to-everything (V2X) communication systems, device-to-device (D2D) communication systems, vehicle-to-everything (V2X) communication systems, fourth-generation (4G) mobile communication systems, such as long-term evolution (LTE) systems, worldwide interoperability for microwave access (WiMAX) communication systems, fifth-generation (5G) systems, such as new radio (NR) systems, and future communication systems, etc.

Furthermore, combinations of these approaches are also possible.

Any embodiment or design scheme described as "exemplary" in this application should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of the term "exemplary" is intended to present the concept in a concrete manner.

[0069] Figure 1 This is a schematic diagram of the architecture of a multi-beam communication system provided in an embodiment of this application. Figure 1 As shown, the communication system includes a terminal device 100 and a network device 200, and the terminal device 100 and the network device 200 are communicatively connected.

[0070] The terminal device 100 can be a terminal device with transceiver functions, or a chip or chip system that can be installed in the terminal device. The terminal device 100 can also be referred to as user equipment (UE), access terminal equipment, subscriber unit, user station, mobile station (MS), mobile station, remote station, remote terminal equipment, mobile device, user terminal equipment, terminal equipment, wireless communication equipment, user agent, or user device.

Alternatively, the terminal device may also be a customer-premises equipment (CPE).

[0071] Network device 200 can be an access network (AN) device, or a radio access network (RAN) device. RAN devices provide access functions for terminal devices and are responsible for functions such as radio resource management, quality of service (QoS) management, data compression, and encryption on the air interface side.

[0072] Understandable. Figure 1 This is a simplified diagram for ease of understanding. The communication system may also include other network devices and / or other terminal devices. Figure 1 It was not drawn.

[0073] like Figure 2 As shown, this embodiment of the invention provides a multi-beam communication method applied to a terminal device, including:

[0074] S110. Receive several reference signals sent by the network device through several antenna panels, and determine the optimal beam for each antenna panel based on the signal reception quality information of the reference signals.

[0075] The signal reception quality information of the reference signal characterizes the signal reception performance of the reference signal. This information includes, but is not limited to, the reference signal receiving power (RSRP). The optimal beam characterizes the beam with the highest signal reception quality of the reference signal.

[0076] The optimal beam for each antenna panel is the beam with the best signal quality when receiving the reference signal, i.e., the beam with the highest reference signal receiving power (RSRP). Network devices and terminal devices can schedule the transmission and reception times of the reference signal. Based on this, the network device sends the reference signal to the terminal device, which can then receive the reference signal using each beam of each antenna panel to determine the RSRP of each beam on each antenna panel, thereby determining the optimal beam for each antenna panel.

[0077] S120. Send the measurement results to the network device; the measurement results include the identification information of the best beam of several antenna panels and the signal reception quality information of the corresponding reference signal.

[0078] The identification information of the optimal beam represents the distinguishing information of the optimal beam, including but not limited to the identifier corresponding to the optimal beam or the identifier of the reference signal corresponding to the optimal beam. Measurement results can be used to indicate multiple optimal beams. For example, the measurement results may include the identifier of each optimal beam among multiple optimal beams, or the identifier of the reference signal corresponding to each optimal beam among multiple optimal beams, and the RSRP corresponding to each optimal beam among multiple optimal beams. That is, the measurement results may include: the correspondence between each optimal beam and the reference signal corresponding to that optimal beam, and the RSRP corresponding to each optimal beam. In this case, since the network device knows the correspondence between the reference signal and the network device's beam, or in other words, the network device knows which beam of the network device was used to transmit the reference signal, the network device can determine the correspondence between the network device's beams and the optimal beams of the terminal device based on the correspondence between each optimal beam and the reference signal corresponding to that optimal beam.

[0079] For example, the measurement results may include: reference signal #1 - beam #1 - RSRP #1, reference signal #1 - beam #2 - RSRP #2, reference signal #2 - beam #3 - RSRP #3, and reference signal #3 - beam #4 - RSRP #2. In this case, reference signal #1 corresponds to beam #a of the network device, reference signal #2 corresponds to beam #b of the network device, and reference signal #3 corresponds to beam #c of the network device. Therefore, the network device determines that beam #a corresponds to beams #1 and #2, beam #b corresponds to beam #3, and beam #c corresponds to beam #4.

[0080] S130. Receive first indication information sent by the network device, determine a first beam set for performing uplink simultaneous interpretation based on the first indication information, and perform uplink simultaneous interpretation using the first beam set; the first indication information is determined based on the measurement results.

[0081] The first indication information is used to instruct the terminal device to perform uplink simultaneous transmission using a first set of beams from a plurality of optimal beams. The first set of beams may include at least some of the beams from the plurality of optimal beams.

[0082] The network device determines the first indication information based on the measurement results and sends the first indication information to the terminal device. After receiving the first indication information, the terminal device first determines the first beam set for performing uplink simultaneous interpretation based on the first indication information, and then performs uplink simultaneous interpretation using the determined first beam set.

[0083] Optionally, see Figure 3 Communication methods applied to terminal devices also include:

[0084] S140. During the uplink simultaneous transmission process, if the uplink quality of the first beam in the first beam set does not meet the standard, a second indication message is sent to the network device; the second indication message indicates that the uplink quality of the first beam does not meet the standard.

[0085] During uplink simultaneous transmission using the first beam set, if the terminal device determines that the uplink transmission quality of the first beam in the first beam set is poor, the terminal device sends a second indication message to the network device. This allows the network device to determine a third indication message based on the second indication message and then send the third indication message back to the terminal device. The second indication message indicates that the uplink quality of the first beam does not meet preset requirements.

[0086] S150. Receive the third indication information sent by the network device, determine the second beam set for performing uplink simultaneous interpretation based on the third indication information, and perform uplink simultaneous interpretation using the second beam set; the third indication information is determined based on the measurement results and the second indication information.

[0087] The terminal device receives a third indication message from the network device, determines a second beam set for performing uplink simultaneous transmission based on the third indication message, and performs uplink simultaneous transmission using the second beam set. The third indication message indicates that the terminal device needs to use the second beam set from among multiple optimal beams for uplink simultaneous transmission; the second beam set does not include the first beam.

[0088] In other words, since the network device knows in advance which beams the terminal device can use for uplink transmission, when the network device learns that the uplink transmission quality of certain beams is poor, the network device can instruct the terminal device to use other beams to continue performing uplink transmission to ensure transmission quality.

[0089] Optionally, see Figure 4 The uplink quality of the first beam in the first beam set was determined to be substandard using the following method:

[0090] S141. During the uplink simultaneous transmission process, if there is a target object in the beam pointing direction of the first beam, reduce the uplink transmission power of the first beam.

[0091] S142. If the uplink transmission power of the first beam is less than the uplink transmission power threshold, it is determined that the uplink quality of the first beam in the first beam set is not up to standard.

[0092] During uplink simultaneous transmission using the first beamset, if a target object is present in the direction of the first beam's pointing, the terminal device determines to reduce the uplink transmission power of the first beam. If the uplink transmission power of the first beam is reduced to below the uplink transmission power threshold, the terminal device determines that the uplink transmission quality of the first beam is poor. The target object can be a human body or any other entity whose electromagnetic radiation level needs to be controlled. In this case, the terminal device needs to reduce the uplink transmission power of the first beam to ensure that its electromagnetic radiation to the target object is within a controllable range or within the limits permitted by regulations.

[0093] Optionally, see Figure 5 Communication methods applied to terminal devices also include:

[0094] S160. During the uplink simultaneous transmission process, if the uplink quality of all beams in the first beam set fails to meet the standard, a fourth indication message is sent to the network device; the fourth indication message indicates that the uplink quality of all beams in the first beam set fails to meet the standard.

[0095] During uplink simultaneous transmission using the first beam set, the terminal device determines that the uplink transmission quality of all beams in the first beam set is poor. For example, if a target object exists in the pointing direction of the first beam set, the terminal device determines to reduce the uplink transmission power of the first beam set. If the uplink transmission power of the first beam set is reduced to below the uplink transmission power threshold, the terminal device determines that the uplink transmission quality of all beams in the first beam set is poor. Based on this, the terminal device can send fourth indication information to the network device. This fourth indication information can be used to indicate that the uplink transmission quality of all beams in the first beam set is poor.

[0096] S170. Receive fifth indication information sent by the network device, and send a target beam to at least one reflecting device according to the fifth indication information, so that the reflecting device reflects the target beam back to the network device; wherein the beams of the reflecting device and the first beam set point in different directions; the fifth indication information is determined according to the fourth indication information.

[0097] The network device receives a fourth indication from the terminal device, and based on this fourth indication, determines at least one reflecting device that is not located in the beam pointing direction of the first beam set. This at least one reflecting device can be an intelligent reflecting surface (IRS) used to reflect the received beam back to the network device; for example, it can enhance the received beam before reflecting the enhanced beam back to the network device. In other words, poor uplink transmission quality for all beams in the first beam set may indicate that multiple optimal beams of the terminal device are blocked, thus requiring a new uplink transmission method, such as reflecting beams back to the network device via reflecting devices, to ensure transmission quality. The network device can send a fifth indication to the terminal device, which in turn receives this fifth indication. This fifth indication indicates that the terminal device needs to send beams to at least one reflecting device. For example, the fifth indication may include the identifier of each of the at least one reflecting device, as well as the location information of each of the at least one reflecting device. Since the terminal device and the network device have agreed on the reflective devices in advance, the terminal device can determine which reflective devices to send beams to and the specific locations of these reflective devices based on the identifiers and location information of at least one reflective device, and then send the target beams in the direction of that location.

[0098] It is understandable that if the uplink transmission quality of all beams in the first beam set is poor, the network device can still use the method of changing beams.

[0099] On the other hand, see Figure 6This invention provides a multi-beam communication method applied to network devices, comprising:

[0100] S210, Send several reference signals to the terminal equipment.

[0101] The network device sends a reference signal to the terminal device. The terminal device receives the reference signal through its antenna panel and records relevant information such as the signal reception quality of the reference signal. Based on the relevant information of the reference signal, it generates measurement results and sends the measurement results to the network device.

[0102] S220, Receive measurement results sent by the terminal device; the measurement results include the identification information of the best beam of several antenna panels and the signal reception quality information of the corresponding reference signal, and the measurement results are determined by the terminal device based on the reference signal received by several antenna panels.

[0103] The network device receives measurement results sent by the terminal device. The measurement results include the identification information of the best beams of several antenna panels and the signal reception quality information of the corresponding reference signals. The signal reception quality information includes, but is not limited to, the RSRP of multiple best beams.

[0104] S230. Determine the first indication information based on the measurement results and send the first indication information to the terminal device so that the terminal device determines the first beam set for performing uplink simultaneous interpretation based on the first indication information and performs uplink simultaneous interpretation using the first beam set.

[0105] The network device determines first indication information based on the measurement results and sends the first indication information to the terminal device, so that the terminal device determines the first beam set for performing uplink simultaneous interpretation based on the first indication information and uses the first beam set to perform uplink simultaneous interpretation. The first indication information is used to indicate to the terminal device that it needs to use the first beam set from multiple optimal beams to perform uplink simultaneous interpretation.

[0106] Specifically, the network device can determine the first beam set based on the RSRPs of each of the multiple optimal beams. For example, the network device can select a preset number of beams from the multiple optimal beams in descending order of RSRP, and determine these selected beams as the first beam set. Alternatively, the network device can determine the first beam set in any other possible way, without specific limitations.

[0107] For example, when the preset number of beams is 2, the network device can select the beams corresponding to RSRP#2 and RSRP#4 in descending order, such as RSRP#2 > RSRP#4 > RSRP#1 > RSRP#3, i.e., beams#2 and#4 as the first beam set.

[0108] Optionally, see Figure 7 Communication methods applied to network devices also include:

[0109] S240, Receive the second indication information sent by the terminal device; the second indication information indicates that the uplink quality of the first beam in the first beam set is not up to standard;

[0110] S250. Determine the third indication information based on the second indication information and the measurement results, and send the third indication information to the terminal device so that the terminal device can determine the second beam set for performing uplink simultaneous interpretation based on the third indication information and perform uplink simultaneous interpretation using the second beam set.

[0111] During the uplink simultaneous transmission process performed by the terminal device, if the network device receives a second indication information sent by the terminal device, the second indication information indicates that the uplink quality of the first beam in the first beam set is not up to standard; the network device removes the first beam with the uplink quality that is not up to standard from the first beam set in the second indication information, and selects other beams with better signal reception quality from the measurement results for use in uplink simultaneous transmission, generates a second beam set based on the modified simultaneous transmission beams, generates a third indication information based on the second beam set, and sends the third indication information to the terminal device, so that the terminal device determines the second beam set for performing uplink simultaneous transmission based on the third indication information and uses the second beam set to perform uplink simultaneous transmission.

[0112] For example, if the terminal device determines that the transmission quality of beam #2 is poor, the second indication information that the terminal device can report may include: beam #2 and an indication cell, the indication cell being used to indicate that the transmission quality of the beam is poor. The network device can determine a second beam set based on the second indication information, such as continuing to select a preset number of beams in descending order of RSRP, including beam #4 and beam #1.

[0113] Optionally, see Figure 8 Communication methods applied to network devices also include:

[0114] S260, Receive the fourth indication information sent by the terminal device; the fourth indication information indicates that the uplink quality of all beams in the first beam set is not up to standard.

[0115] During the uplink simultaneous transmission process performed by the terminal device, when the uplink quality of all beams in the first beam set fails to meet the standard, the terminal device sends a fourth indication message to the network device. The fourth indication message indicates that the uplink quality of all beams in the first beam set fails to meet the standard.

[0116] S270. Determine the fifth instruction information according to the fourth instruction information and send the fifth instruction information to the terminal device so that the terminal device sends a target beam to at least one reflecting device, and the target beam is reflected by the reflecting device to the network device; wherein the beams of the reflecting device and the first beam set point in different directions.

[0117] The network device determines a fifth indication based on the received fourth indication and sends the fifth indication to the terminal device. The fifth indication instructs the terminal device to send a target beam to at least one reflecting device. The terminal device sends the target beam to the at least one reflecting device, which reflects the target beam towards the network device; wherein the beams of the reflecting devices and the first beam set point in different directions.

[0118] Implementing this embodiment of the invention provides the following beneficial effects: In this embodiment, firstly, the network device sends several reference signals to the terminal device. These reference signals are used to test the communication quality of the terminal device. Next, the terminal device receives these reference signals from the network device through several antenna panels. Based on the signal reception quality information of the reference signals, it determines the optimal beam for each antenna panel. Based on the identification information of the optimal beams of the antenna panels and the corresponding signal reception quality information of the reference signals, it determines the measurement result and sends the measurement result to the network device. Based on the measurement result, the signal reception quality of each beam can be accurately determined. Then, the network device receives the measurement result, determines first indication information based on the measurement result, and sends the first indication information to the terminal device. The first indication information includes information about beams with better signal reception quality. Next, the terminal device receives the first indication information, determines a first beam set for performing uplink simultaneous transmission based on the first indication information, and performs uplink simultaneous transmission using the first beam set. The first beam set with better signal reception quality is selected for uplink simultaneous transmission, thereby enabling the network device to accurately schedule the terminal device to use beams with better signal transmission quality for uplink simultaneous transmission, ensuring uplink transmission quality.
