Description

Technical Field

[0001] This application relates to the field of communication technologies, and particularly to a beam management method and apparatus. Background Art

[0002] In the current 5th generation mobile communication technology (5G) era, as well as in the future 5G+ and 6G eras, there are problems of signal and energy degradation during the transmission of signals in the medium and high frequency bands (such as 6 GHz, 28 GHz). Usually, a larger antenna array is adopted, and by performing weighted processing on the antenna array, the signal energy is concentrated within a smaller angular range to form a signal similar to a light beam, which is called a beam.

[0003] As the number of communication signals increases, the number of beams transmitted by the antenna also increases accordingly, which results in the processing capacity of the base station being unable to meet the signal processing requirements. To solve the problem that the base station cannot process too many signals, a hybrid beamforming (HBF) architecture is introduced. However, when signal transmission is performed based on the HBF architecture, the performance of the multi-user system may be affected. Summary of the Invention

[0004] This application provides a beam management method and apparatus for implementing analog beam measurement, selection, and reporting under a hybrid beam architecture.

[0005] The technical solutions are as follows:

[0006] In a first aspect, an embodiment of this application provides a beam management method. The method includes: A network device sends M pilot packets to a terminal device. Each of the M pilot packets corresponds to multiple pilot resources or multiple pilot ports, where M is a positive integer. The network device obtains measurement values and index values of at least one of the M pilot packets. The measurement values are used to characterize the channel state information of the pilot packets; the index values are used to characterize the pilot resources or pilot ports associated with the measurement values.

[0007] Wherein, one pilot packet corresponds to one analog beam or multiple digital beams of one analog beam.

[0008] In a possible embodiment, the pilot packet may be a pilot resource set packet or a pilot resource packet. When the pilot packet is a pilot resource set packet, each pilot packet corresponds to multiple pilot resources; when the pilot packet is a pilot port packet, each pilot packet corresponds to multiple pilot ports.

[0009] An example where a network device configures multiple pilot resource sets for a terminal device, where each pilot resource set corresponds to one or more pilot resources. Among them, the pilots included in different pilot resource sets are sent with different analog domain weights and the same or different digital domain weights, that is, the analog beams corresponding to different pilot resource sets are different. Among one or more pilot resources in the same pilot resource set, each pilot resource included is sent with the same analog domain weight and different digital domain weights, that is, the analog beams corresponding to different pilot resources in the same pilot resource set are the same, and the digital beams are different.

[0010] An example where a network device configures a pilot resource set for a terminal device, which includes multiple pilot resources, and each pilot resource corresponds to multiple pilot ports. Among them, the pilots included in different pilot resources are sent with different analog domain weights and the same or different digital domain weights, that is, the analog beams corresponding to different pilot resources are different. Among one or more pilot ports in the same pilot resource, each pilot port included is sent with the same analog domain weight and different digital domain weights, that is, the analog beams corresponding to different pilot ports in the same pilot resource are the same, and the digital beams are different.

[0011] In this application, the network device sends multiple pilot packets to the terminal device. Different pilot packets correspond to different analog beams, and each pilot packet in the multiple pilot packets corresponds to multiple pilot resources or multiple pilot ports. The terminal device calculates the measurement value of each pilot packet according to the multiple pilot packets. The terminal device then reports the measurement value corresponding to each pilot packet to the network device. Since the analog beams of different pilot packets are different, the measurement and reporting of different analog beams can be realized, thereby realizing the perception of different analog beams by the terminal device and improving the communication performance of the multi-user system.

[0048] To facilitate a clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, terms such as "first" and "second" are used to distinguish identical or similar items with basically the same functions and effects. For example, the first valid signal and the second valid signal are only used to distinguish different valid signals, and do not limit their sequence. Those skilled in the art can understand that terms such as "first" and "second" do not limit the quantity and execution order, and "first" and "second" do not necessarily mean different.

[0052] The network architecture and service scenarios described in the embodiments of this application are to more clearly illustrate the technical solutions of the embodiments of this application and do not constitute a limitation on the technical solutions provided by the embodiments of this application. Those of ordinary skill in the art know that with the evolution of the network architecture and the emergence of new service scenarios, the technical solutions provided by the embodiments of this application are equally applicable to similar technical problems. In the embodiments of this application, the method provided is described by taking its application in a New Radio (NR) system or a 5G network as an example.

[0053] Before introducing the embodiments of this application, the following interpretations are made for the relevant terms involved in the embodiments of this application:

[0054] 1) Wave beam: It refers to a signal similar to a light beam formed by concentrating signal energy within a small angular range through weighted processing of the antenna array on the base station side or the terminal side.

[0055] 2) Transmission Configuration Indicator (TCI): It is used to indicate relevant information about the downlink beam in the downlink control information (DCI).

[0056] 3) Spatial relation: It is used to indicate relevant information about the uplink beam.

[0057] As Figure 1 shown, Figure 1 Figure (a) shows a communication system provided by an embodiment of the present application. The communication system includes one or more network devices and one or more terminal devices. For example Figure 1 in Figure (a), multiple terminal devices (such as terminal 102 and terminal 103) communicate with one network device (such as base station 101), Figure 1 and Figure (b) shows one terminal device (such as terminal 107) communicating with multiple network devices (such as base stations 104, 105, and 106).

[0058] Among them, the communication between the network device and the terminal device needs to use a wave beam. The manifestation of the wave beam in NR can be a spatial domain filter, a spatial filter, a spatial domain parameter, a spatial parameter, a spatial domain setting, a spatial setting, Quasi-colocation (QCL) information, a QCL hypothesis, a QCL indication, etc. The wave beam can be indicated by the TCI-state parameter or the spatial relation parameter. Therefore, in the present application, the wave beam can be replaced by a spatial domain filter, a spatial filter, a spatial domain parameter, a spatial parameter, a spatial domain setting, a spatial setting, QCL information, a QCL hypothesis, a QCL indication, TCI-state, spatial relation, etc.

[0059] It can be understood that the wave beam can also be other terms representing the wave beam, which are not limited in the present application.

[0060] Among them, the network device needs to send data information using a transmission beam (Tx beam), and the terminal device needs to receive data information using a reception beam (Rx beam).

[0061] The transmission beam refers to the distribution of signal strength formed in different directions in space after the signal is transmitted by the antenna and is used to transmit signals. The transmission beam can also be a spatial domain transmission filter, a spatial transmission filter, a spatial domain transmission parameter, a spatial transmission parameter, a spatial domain transmission setting, a spatial transmission setting, and the downlink beam can be indicated by the TCI-state parameter.

[0062] The reception beam can refer to the signal strength distribution of the wireless signal received from the antenna in different directions in space and is used to receive signals. The reception beam can also be a spatial domain reception filter, a spatial reception filter, a spatial domain reception parameter, a spatial reception parameter, a spatial domain reception setting, a spatial reception setting, and the uplink beam can be indicated by the spatial relationship, the uplink TCI-state, and the sounding reference signal (SRS) resource.

[0063] In this application, the beam can be a wide beam, a narrow beam, or other types of beams. The technology for forming the beam can be beamforming technology (such as digital beamforming technology, analog beamforming technology, hybrid digital / analog beamforming technology, etc.), or other technologies.

[0064] In an application scenario, during the downlink transmission between a network device and a terminal device, the transmission beam used by the network device is determined by the network device, and the reception beam used by the terminal device is determined by the network device notifying the terminal device.

[0065] As an example, as shown in Figure 1 Figure (a) in, base station 101 sends a downlink control information (DCI) signaling to terminal 102. The DCI signaling contains a TCI field, and this TCI field is used to indicate a TCI-state. This TCI-state includes a target reference signal resource (also known as a pilot resource). For the process of downlink transmission using this TCI-state, terminal 102 receives using the reception beam corresponding to this pilot resource. Among them, the reception beam corresponding to the pilot resource is known to terminal 102 in advance. For example, terminal 102 can obtain the reception beam by measuring this pilot resource.

[0066] As another example, for the process of uplink transmission between the network device and the terminal device, based on the above TCI-state, terminal 102 can use the transmission beam corresponding to this target reference signal resource to send data, or use the reception beam corresponding to this target reference signal resource to send data in reverse.

[0067] Among them, during the communication process between the network device and the terminal device, the network device can indicate multiple different beams for channels and / or reference signals to the terminal device, or can also indicate a beam to the terminal device, and this beam is simultaneously used for multiple channels and / or reference signals, which is called a common beam. It should be noted that the common beam is only for the convenience of description in the embodiments of this application, and it can also have other names, which are not limited in this application.

[0068] As an example, the network device can indicate an uplink common beam to the terminal device for the transmission of multiple uplink channels and / or uplink reference signals; or, the network device can also indicate a downlink common beam to the terminal device for the transmission of multiple downlink channels and / or downlink reference signals; or, the network device can also indicate an uplink and downlink common beam to the terminal device for the transmission of multiple uplink channels and / or uplink reference signals, as well as multiple downlink channels and / or downlink reference signals.

[0069] The terminal device in the embodiments of the present application is a device with wireless communication capabilities. The terminal device is also known as a user equipment (UE), a mobile station (MS), a mobile terminal (MT), etc., and is a device that provides voice and / or data connectivity to users. For example, a handheld device with a wireless connection function, a vehicle-mounted device, etc. Currently, some examples of terminals are: mobile phones, tablet computers, laptop computers, palmtop computers, mobile internet devices (MIDs), wearable devices (such as smart watches, smart bracelets, pedometers, etc.), vehicle-mounted devices (such as cars, bicycles, electric vehicles, airplanes, ships, trains, high-speed rails, etc.), virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in self-driving, wireless terminals in remote medical surgery, wireless terminals in smart grid, wireless terminals in transportation safety, wireless terminals in smart city, wireless terminals in smart home (such as refrigerators, TVs, air conditioners, electricity meters, etc.).

[0071] It should be understood that the network device and the terminal device in the embodiments of the present application can be deployed on land, including indoor or outdoor, handheld or vehicle-mounted; or deployed on water; or deployed on airplanes, balloons, and satellites in the air. The embodiments of the present application do not limit the application scenarios of the network device and the terminal device.

[0072] Figure 2 The figure shows a schematic diagram of the network element structure of a communication device provided by the embodiments of the present application. The network element structures of the terminal device and the network device in the embodiments of the present application can refer to the structure as Figure 2 shown. The communication device includes a processor 201, a communication line, at least one transceiver 202, and an antenna 203.

[0073] The processor 201 can be a general-purpose central processing unit (CPU), a microprocessor, an application-specific integrated circuit (ASIC), or one or more integrated circuits for controlling the execution of the program of the present application solution.

[0074] The communication line may include a path for transmitting information between the above components.

[0075] The transceiver 202, using any device of the transceiver type, is used to communicate with other devices or communication networks, such as Ethernet, radio access network (RAN), wireless local area networks (WLAN), etc.

[0076] The transceiver 202 includes a transmitter 2021 and a receiver 2022. The transmitter 2021 is connected to the antenna 203, and the receiver 2022 is connected to the antenna 203.

[0077] Optionally, the communication device may further include a memory 204.

[0078] The memory 204 may be a read-only memory (ROM) or other type of static storage device that can store static information and instructions, a random access memory (RAM) or other type of dynamic storage device that can store information and instructions, or an electrically erasable programmable read-only memory (EEPROM), a compact disc read-only memory (CD-ROM) or other optical disc storage, optical disc storage (including compact discs, laser discs, optical discs, digital versatile discs, Blu-ray discs, etc.), magnetic disk storage media or other magnetic storage devices, or any other medium that can be used to carry or store the desired program code in the form of instructions or data structures and can be accessed by a computer, but is not limited thereto. The memory 204 may exist independently and be connected to the processor 201 through a communication line. The memory 204 may also be integrated with the processor 201.

[0079] Among them, the memory 204 is used to store computer execution instructions for implementing the solution of this application, and is controlled by the processor 201 for execution. The processor 201 is used to execute the computer execution instructions stored in the memory 204, so as to implement the method provided in the following embodiments of this application.

[0080] Optionally, the computer execution instructions in the embodiments of this application may also be referred to as application code, and the embodiments of this application do not make specific limitations thereon.

[0081] In a specific implementation, as an embodiment, the processor 201 may include one or more CPUs.

[0082] In a specific implementation, as an example, a communication device may include multiple processors, and each of these processors may be a single-CPU processor or a multi-CPU processor. The processor here may refer to one or more devices, circuits, and / or processing cores for processing data (such as computer program instructions).

[0083] The antenna 203 is generally located on an antenna panel, and there is one or more antennas on an antenna panel. One or more antennas are arranged in an antenna array to perform beamforming, thereby forming an analog beam. Among them, the antenna array can generate multiple analog beams in different directions.

[0084] In a specific implementation, the terminal device may be equipped with multiple antenna panels, and the multiple antenna panels are distributed at different positions and face different directions, ensuring that no matter which direction the terminal device faces, there is at least one antenna panel facing the network device, so as to perform data transmission with the network device.

[0085] Optionally, the terminal device may simultaneously turn on all antenna panels for transmission, or alternatively, may use only a single antenna panel for transmission at a time. Whether the antenna panel of the terminal device is in an open or closed state generally needs to be notified to the network device.

[0086] In the embodiments of the present application, the antenna panel can also be represented in other ways. For example, the antenna panel can be characterized by an antenna port (such as a channel state information-reference signal (CSI-RS) port, a sounding reference signal (SRS) port, a demodulation reference signal (DMRS) port, a phase tracking reference signal (PTRS) port, a cell reference signals (CRS) port, a tracking reference signal (TRS) port, a synchronization signal and physical broadcast channel block (SSB) port) or an antenna port group; it can also be characterized by a resource (such as a CSI-RS resource, an SRS resource, a DMRS resource, a PTRS resource, a CRS resource, a TRS resource, an SSB resource, etc.) or a resource group; it can also be characterized by a certain channel (such as a physical uplink control channel (PUCCH), a physical uplink sharing channel (PUSCH), a physical random access channel (PRACH), a physical downlink sharing channel (PDSCH), a physical downlink control channel (PDCCH), a physical broadcast channel (PBCH), etc.); it can also be characterized by a beam, QCL, TCI-state, spatial relation or an index configured in QCL, TCI-state, spatial relation; it can also be characterized by a beam group, a QCL group, a TCI-state group, a spatial relation group, etc., which are not limited in the embodiments of the present application.

[0087] In the prior art, each beam corresponds to a pilot resource. By measuring the pilot resource, a communication device can obtain the quality of the beam. Taking the transmit beam of a network device as an example, after the network device configures the pilot resource for a terminal device, the terminal device measures the pilot resource to obtain a measurement value and reports the measurement value to the network device. The network device can know the quality of the beam corresponding to the pilot resource based on the measurement value.

[0088] Currently, due to the increase in the number of beams, the processing burden on the communication device has increased. Therefore, in some related technologies, a large-array hybrid beamforming (HBF) architecture is usually used. The HBF architecture solves the problem of the decline in the processing ability of the communication device caused by the excessive number of beams. Specifically, first, analog beamforming is performed on the transmit beams of the network device and combined into multiple analog-domain beams (also called analog beams), and then digital beamforming is performed on the multiple analog-domain beams and combined into multiple digital-domain beams (also called digital beams). At this time, each analog beam corresponds to a pilot resource. For example, the pilot resource configured by the network device for the terminal device includes a resource set, and each resource set includes multiple resources. The resource is the pilot resource corresponding to each analog beam, and each resource includes 1 or 2 pilot ports. Based on the measurement values measured from multiple resources, the terminal device selects 1 to 4 resources and the corresponding measurement values of each resource and reports them to the network device. The network device can know the quality of the analog beam. It can be understood that if the resource includes 1 pilot port, the reported measurement value is the measurement value of the pilot port. If the resource includes 2 pilot ports, the reported measurement value is the average of the measurement values of the 2 pilot ports.

[0089] However, since there are multiple digital beams in the same analog beam, at this time, different pilot resources need to be configured for different digital beams under the same analog beam. When the terminal device selects 1 to 4 from multiple pilot resources for reporting, since the terminal device cannot perceive the specific weighting method of the pilot resources (such as the analog beamforming method and the digital beamforming method), the selected pilot resources may be based on different digital beams under the same analog beam, which results in the inability to effectively measure different analog beams.

[0090] To solve the above problems, the present application proposes a beam management method. By grouping the pilot resources for beam management, the pilot resources of the same analog beam are in the same group, and the pilot resources of different analog beams are in different groups. The group-level measurement values are measured, and pilot resources are selected from different groups and reported to the network device, so as to realize the measurement, selection, and reporting of analog beams under the HBF architecture.

[0091] In the embodiments of the present application, the specific structure of the execution subject of a beam management method is not particularly limited in the embodiments of the present application. As long as a program recording the code of a beam management method in the embodiments of the present application can be run to communicate according to a beam management method in the embodiments of the present application. For example, the execution subject of a beam management method provided in the embodiments of the present application can be a functional module in a network device that can call and execute the program, or a communication device applied to the network device, such as a chip. The execution subject of a beam management method provided in the embodiments of the present application can be a functional module in a terminal device that can call and execute the program, or a communication device applied to the terminal device, such as a chip. The present application does not limit this.

[0092] As Figure 3 shown in the flowchart of a beam management method provided in the embodiments of the present application, the method includes:

[0093] Step 301: The network device sends M pilot packets to the terminal device. Correspondingly, the terminal device receives M pilot packets from the network device. Each pilot packet in the M pilot packets corresponds to multiple pilot resources or multiple pilot ports, and M is a positive integer.

[0094] Among them, a pilot packet refers to a grouped pilot. For example, it can be a set of grouped pilot resources or a grouped pilot resource. A pilot packet corresponds to one analog beam or multiple digital beams of one analog beam.

[0095] A pilot packet corresponds to one analog beam or multiple digital beams of one analog beam.

[0096] For example, the network device sends 3 pilot packets to the terminal device, namely pilot packet 1, pilot packet 2, and pilot packet 3. The analog beams corresponding to the 3 pilot packets are analog beam 1, analog beam 2, and analog beam 3 respectively. When pilot packet 1 corresponds to 3 pilot resources, pilot resources 1, 2, and 3 correspond to analog beam 1 and respectively correspond to digital beams 1, 2, and 3. Or, when pilot packet 1 corresponds to 3 pilot ports, pilot ports 1, 2, and 3 correspond to analog beam 1 and respectively correspond to digital beams 1, 2, and 3.

[0097] Among them, the pilot resources may be channel state information-reference signal (CSI-RS) resources, sounding reference signal (SRS) resources, demodulation reference signal (DMRS) resources, phase tracking reference signal (PTRS) resources, cell reference signals (CRS) resources, tracking reference signal (TRS) resources, synchronization signal and physical broadcast channel block (SSB) resources, etc., which are not limited in the embodiments of this application.

[0098] Among them, the pilot ports may also be physical antennas, antenna ports, reference signal ports, virtual ports, etc. The pilot ports include CSI-RS ports, SRS ports, DMRS ports, PTRS ports, CRS ports, TRS ports, SSB ports, etc., which are not limited in the embodiments of this application.

[0099] In a possible embodiment, the pilot grouping may be a pilot resource set (resourceSet) grouping, a pilot resource (resource) grouping, or a pilot port (port) grouping. When the pilot grouping is a pilot resource set grouping, each pilot grouping corresponds to multiple pilot resources; when the pilot grouping is a pilot port grouping, each pilot grouping corresponds to multiple pilot ports.

[0100] As an example, the network device configures multiple pilot resource sets for the terminal device, where each pilot resource set corresponds to one or more pilot resources. Among them, the pilots included in different pilot resource sets are transmitted with different analog domain weights and the same or different digital domain weights, that is, the analog beams corresponding to different pilot resource sets are different. Among the one or more pilot resources in the same pilot resource set, each pilot resource included is transmitted with the same analog domain weight and different digital domain weights, that is, the analog beams corresponding to different pilot resources in the same pilot resource set are the same, and the digital beams are different.

[0101] For example, the network device configures four pilot resource sets, namely resourceSet#1, resourceSet#2, resourceSet#3, and resourceSet#4, for the terminal device. Each pilot resource set includes four pilot resources, namely resource#1, resource#2, resource#3, and resource#4. The analog beams corresponding to resourceSet#1, resourceSet#2, resourceSet#3, and resourceSet#4 are analog beam 1, analog beam 2, analog beam 3, and analog beam 4, respectively. The pilots included in the four pilot resources in resourceSet#1 are transmitted using digital domain weights 1, 2, 3, and 4, respectively. The same applies to the pilot resources in resourceSet#2, resourceSet#3, and resourceSet#4, which will not be elaborated here.

[0102] It should be noted that the pilots included in the four pilot resources in resourceSet#2, or resourceSet#3, or resourceSet#4 can be transmitted using the same or different digital domain weights as those used for the pilots included in the four pilot resources in resourceSet#1. For example, the pilots included in the four pilot resources in resourceSet2 can also be transmitted using digital domain weights 1, 2, 3, and 4, respectively, or using digital domain weights 4, 5, 6, and 7. This is not limited in the embodiments of this application.

[0103] In an embodiment of the present application, the pilot resource set may be a channel state information - synchronization signal and physical broadcast channel block - resource set (CSI - SSB - resourceSet), or a channel state information - interference measurement - resource set (CSI - IM - resourceSet), or a non - zero power - channel state information - reference signal - resource set (NZP - CSI - RS - resourceSet), or a zero power - channel state information - reference signal - resource set (ZP - CSI - RS - resourceSet), which is not limited in the embodiments of the present application.

[0104] As another example, the network device configures a pilot resource set for the terminal device, which includes multiple pilot resources, and each pilot resource corresponds to multiple pilot ports. Among them, the pilots included in different pilot resources are sent with different analog domain weights and the same or different digital domain weights, that is, the analog beams corresponding to different pilot resources are different. Among one or more pilot ports in the same pilot resource, the pilots included in each pilot port are sent with the same analog domain weight and different digital domain weights, that is, the analog beams corresponding to different pilot ports in the same pilot resource are the same, and the digital beams are different.

[0105] For example, a network device configures a pilot resource set resourceSet#1 for a terminal device. ResourceSet#1 includes four pilot resources, namely resource#1, resource#2, resource#3, and resource#4. Each pilot resource includes four pilot ports, namely port#1, port#2, port#3, and port#4. The analog beams corresponding to resource#1, resource#2, resource3, and resource#4 are analog beam 1, analog beam 2, analog beam 3, and analog beam 4, respectively. The pilots included in the four pilot ports in resource#1 are transmitted using digital domain weights 1, digital domain weight 2, digital domain weight 3, and digital domain weight 4, respectively. The same applies to the pilot ports in resource#2, resource#3, and resource#4, which will not be elaborated here.

[0106] It should be noted that the pilots included in the four pilot resources in resource#2, or resource#3, or resource#4 can be transmitted using digital domain weights that are the same as or different from those used for the pilots included in the four pilot ports in resource#1. For example, the pilots included in the four pilot ports in resource#2 can also be transmitted using digital domain weights 1, digital domain weight 2, digital domain weight 3, and digital domain weight 4, respectively, or using digital domain weights 4, digital domain weight 5, digital domain weight 6, and digital domain weight 7. This is not limited in the embodiments of the present application.

[0107] Optionally, in the case where the pilot grouping is pilot port grouping, polarization grouping can be performed on the multiple pilot ports included in each pilot resource. It can be understood that every two pilot ports correspond to one beam.

[0108] In an embodiment of the present application, when the pilot grouping corresponds to L pilot ports and L is an even number, every two pilot ports form a group and correspond to one analog beam, including: the kth pilot port and the (k + N / 2)th pilot port correspond to one group, where k is a positive integer. Or, the kth pilot port and the (k + 1)th pilot port correspond to one group, where k is an odd number.

[0109] For example, take the case where the pilot resource resource#1 includes 8 pilot ports port#1 to port#8. Port#1 and port#5 correspond to one analog beam, port#2 and port#6 correspond to one analog beam, port#3 and port#7 correspond to one analog beam, and port#4 and port#8 correspond to one analog beam. It can be understood that among the 8 pilot ports, the first half of the pilot ports are of the same polarization beam, and the second half of the pilot ports are of another polarization beam. Or, port#1 and port#2 correspond to one analog beam, port#3 and port#4 correspond to one analog beam, port#5 and port#6 correspond to one analog beam, and port#7 and port#8 correspond to one analog beam. It can be understood that among the 8 pilot ports, the pilot ports with odd numbers are of the same polarization beam, and the pilot ports with even numbers are of another polarization beam.

[0110] In an embodiment of the present application, the pilot resource may be CSI-SSB-resource, or CSI-IM-resource, or NZP-CSI-RS-resource, or ZP-CSI-RS-resource, which is not limited in the embodiments of the present application.

[0111] Step 302: The terminal device obtains the measurement value of each pilot packet.

[0112] The measurement value is used to characterize the channel state information of the pilot packet, and the measurement value may be any one of reference signal received power (RSRP), or reference signal receiving quality (RSRQ), or signal to interference plus noise ratio (SINR).

[0113] Among them, when each pilot packet corresponds to a pilot resource set, the measurement value of the pilot packet is the measurement value of the pilot resource set; when each pilot packet corresponds to a pilot resource, the measurement value of each pilot packet is the measurement value of the pilot resource.

[0114] In a possible embodiment of the present application, when each pilot packet corresponds to multiple pilot resources, determining the measurement value corresponding to each pilot packet includes: the terminal device determines the measurement value of each pilot resource among the multiple pilot resources corresponding to each pilot packet.

[0115] As an example, the terminal device measures the measurement values of each pilot resource according to multiple pilot resources in each pilot resource set, and then determines the measurement value of the pilot resource set according to the measurement values of each pilot resource.

[0116] It can be understood that the measurement value of the pilot resource set is determined by the measurement values of multiple pilot resources in the pilot resource set. Specifically, the measurement value corresponding to each pilot group includes one or more of the following: the average value or the maximum value of the measurement values of multiple pilot resources; or, the measurement values of multiple pilot resources are arranged in a preset order, and the average value or the sum value of the first N measurement values, where N is a positive integer.

[0117] For example, taking the measurement value as RSRP, the network device configures multiple pilot resource sets (resourceSet) for the terminal device, each pilot resource set includes multiple pilot resources (resource), the terminal device calculates the RSRP of each pilot resource, and takes the maximum RSRP within the same pilot resource set as the RSRP of the pilot resource set.

[0118] For example, resourceSet#1 includes four pilot resources, namely resource#1, resource#2, resource#3, and resource#4. The terminal device calculates that the RSRPs of resource#1, resource#2, resource#3, and resource#4 are RSRP1, RSRP2, RSRP3, and RSRP4 respectively. After comparing the four RSRPs, it is determined that RSRP2 is the maximum value, then RSRP2 is taken as the RSRP of resourceSet#1.

[0119] For example, taking the measurement value as RSRP, the network device configures multiple pilot resource sets (resourceSet) for the terminal device, each pilot resource set includes multiple pilot resources (resource), the terminal device calculates the RSRP of each pilot resource, compares the multiple RSRPs within the same pilot resource set, arranges them in a preset order, and takes the average or sum of the largest first N RSRPs as the RSRP of the pilot resource set.

[0120] For example, resourceSet#1 includes four pilot resources: resource#1, resource#2, resource#3, and resource#4. The terminal device calculates that the RSRPs of resource#1, resource#2, resource#3, and resource#4 are RSRP1, RSRP2, RSRP3, and RSRP4 respectively. The four RSRPs are compared and sorted in a preset order (from largest to smallest), determining that RSRP1 > RSRP2 > RSRP4 > RSRP3. Taking N as 2, that is, taking the first two RSRPs (RSRP1 and RSRP2) for averaging to obtain RSRP*, and using RSRP* as the RSRP of resourceSet#1; or, performing summation to obtain RSRP+, and using RSRP+ as the RSRP of resourceSet#1.

[0121] It should be noted that the preset order can also be from smallest to largest, or other permutation orders, which are not limited in the embodiments of the present application.

[0122] Optionally, after the terminal device calculates the RSRP of each pilot resource in a pilot resource set, it selects the RSRPs of N pilot resources for averaging or summation as the RSRP of this pilot resource set. Among them, the N pilot resource numbers selected for different pilot resource sets are the same.

[0123] For example, if the RSRPs of resource#1 and resource#3 in resourceSet#1 are selected for averaging or summation, then the RSRPs of resource#1 and resource#3 in resourceSet#2 are also selected for averaging or summation in resourceSet#2.

[0124] It should be noted that the value of N can be configured by the network device or determined by the terminal device, which is not limited in the embodiments of the present application.

[0125] Optionally, after the terminal device calculates the RSRP of each pilot resource in a pilot resource set, it averages or sums the RSRPs of the pilot resources with the same number in different pilot resource sets as the RSRP of the pilot resource.

[0126] For example, resourceSet#1, resourceSet#2, and resourceSet#3 all include four pilot resources: resource#1, resource#2, resource#3, and resource#4. After the terminal device calculates the RSRP of each pilot resource in each pilot resource set, it averages or sums the RSRP of resource#1 in resourceSet#1, resource#1 in resourceSet#2, and resource#1 in resourceSet#3 as the RSRP of resource#1. Or it averages or sums the RSRP of resource#2 in resourceSet#1, resource#2 in resourceSet#2, and resource#2 in resourceSet#3 as the RSRP of resourcet#2.

[0127] In another possible embodiment of the present application, when each pilot packet corresponds to multiple pilot ports, determining the measurement value corresponding to each pilot packet includes: the terminal device determines the measurement value of each pilot port among the multiple pilot ports corresponding to each pilot packet.

[0128] As another example, the terminal device measures the measurement values of one or more pilot ports according to one or more pilot ports in each pilot resource, and then determines the measurement value of the pilot resource according to the measurement values of the one or more pilot ports.

[0129] It can be understood that the measurement value of the pilot resource is determined by the measurement values of multiple pilot ports in the pilot resource. Specifically, the measurement value corresponding to each pilot packet includes one or more of the following: the average value or the maximum value of the measurement values of multiple pilot ports; or, the measurement values of multiple pilot ports are arranged in a preset order, and the average value or the sum value of the first N measurement values, where N is a positive integer.

[0130] Illustrated by way of example, taking the measurement value as RSRP, the network device configures a pilot resource set (resourceSet) for the terminal device, which includes multiple pilot resources (resource), and each pilot resource includes multiple pilot ports (port). The terminal device calculates the RSRP of each pilot port and takes the maximum RSRP within the same pilot resource as the RSRP of the pilot resource.

[0131] For example, resource#1 includes four pilot ports: port#1, port#2, port#3, and port#4. The terminal device calculates the RSRP of port#1, port#2, port#3, and port#4 as RSRP1, RSRP2, RSRP3, and RSRP4 respectively. The four RSRPs are compared, and it is determined that RSRP2 is the maximum value. Then, RSRP2 is used as the RSRP of resource#1.

[0132] For example, taking the measured value as RSRP, the network device configures a pilot resource set (resourceSet) for the terminal device, which includes multiple pilot resources (resource). Each pilot resource includes multiple pilot ports (port). The terminal device calculates the RSRP of each pilot port, compares the multiple RSRPs within the same pilot resource, arranges them in a preset order, and takes the average or sum of the top N largest RSRPs as the RSRP of this pilot resource.

[0133] For example, resource#1 includes four pilot ports: port#1, port#2, port#3, and port#4. The terminal device calculates the RSRP of port#1, port#2, port#3, and port#4 as RSRP1, RSRP2, RSRP3, and RSRP4 respectively. The four RSRPs are compared and sorted in a preset order (for example, in descending order), and it is determined that RSRP1 > RSRP2 > RSRP4 > RSRP3. Taking N as 2, that is, taking the average of the first two RSRPs (RSRP1 and RSRP2) to obtain RSRP*, and using RSRP* as the RSRP of resource1; or, summing them to obtain RSRP+, and using RSRP+ as the RSRP of resource#1.

[0134] Optionally, after the terminal device calculates the RSRP of each pilot port in a pilot resource, it selects the RSRP of N pilot ports for averaging or summing as the RSRP of this pilot resource. Among them, the numbers of the N pilot ports selected for different pilot resources are the same.

[0135] For example, if the RSRP of port#1 and port#3 in resource#1 is selected for averaging or summing, then the RSRP of port#1 and port#3 in resource#2 is also selected for averaging or summing in resource#2.

[0136] Optionally, after the terminal device calculates the RSRP of each pilot port in a pilot resource, it averages or sums the RSRPs of the pilot ports with the same number in different pilot resources as the RSRP of the pilot port.

[0137] For example, resource#1, resource#2, and resource#3 included in resourceSet#1 all include four pilot ports: port#1, port#2, port#3, and port#4. After the terminal device calculates the RSRP of each pilot port in each pilot resource, it averages or sums the RSRPs of port#1 in resource#1, port#1 in resource#2, and port#1 in resource#3 as the RSRP of port#1. Or it averages or sums the RSRPs of port#2 in resource#1, port#2 in resource#2, and port#2 in resource#3 as the RSRP of port#2.

[0138] It should be noted that the receiving beams used by the terminal device to receive pilot signals of different pilot resource sets, or different pilot resources, or different pilot ports can be the same or different, which is not limited in the embodiments of the present application.

[0139] Step 303: The network device obtains the measurement values and index values of at least one pilot packet among the M pilot packets. Correspondingly, the terminal device reports the measurement values and index values of at least one pilot packet among the M pilot packets to the network device.

[0140] Among them, the measurement value is used to characterize the channel state information of the pilot packet.

[0141] As an example, when the pilot packet is a pilot resource packet, the measurement value of the pilot packet is the measurement value of the pilot resource set, or the measurement value of the pilot packet is the combined measurement value of the pilot resources with the same index in multiple pilot resource sets, and the terminal device reports the measurement value of each pilot resource set to the network device.

[0142] The following takes the network device configuring four pilot resource sets, namely resourceSet#0, resourceSet#1, resourceSet#2, and resourceSet#3, for the terminal device as an example. Each pilot resource set includes four pilot resources: resource#0, resource#1, resource#2, and resource#3, to illustrate the measurement values corresponding to each pilot packet reported by the terminal device to the network device.

[0143] Example 1: The terminal device selects the same pilot resource (such as selecting resource#0 in each pilot resource set) in different pilot resource sets for RSRP calculation, and uses the RSRP corresponding to this pilot resource (for example, the RSRP of resource#0 in resourceSet#0 is RSRP0, the RSRP of resource#0 in resourceSet#1 is RSRP1, the RSRP of resource#0 in resourceSet#2 is RSRP2, and the RSRP of resource#0 in resourceSet#3 is RSRP3) as the RSRP of the corresponding pilot resource set, and reports it to the network device. That is, RSRP0 is the RSRP of resourceSet#0, RSRP1 is the RSRP of resourceSet#1, RSRP2 is the RSRP of resourceSet#2, and RSRP3 is the RSRP of resourceSet#3.

[0144] Example 2: The RSRP0 reported by the terminal device is the average value or the sum of the RSPR corresponding to resource#0 of resourceSet#0, resource#0 of resourceSet#1, resource#0 of resourceSet#2, and resource#0 of resourceSet#3; RSRP1 is the average value or the sum of the RSPR measurement values corresponding to resource#1 of resourceSet#0, resource#1 of resourceSet#1, resource#1 of resourceSet#2, and resource#1 of resourceSet#3; RSRP2 is the average value or the sum of the RSPR measurement values corresponding to resource#2 of resourceSet#0, resource#2 of resourceSet#1, resource#2 of resourceSet#2, and resource#2 of resourceSet#3; RSRP3 is the average value or the sum of the RSPR measurement values corresponding to resource#3 of resourceSet#0, resource#3 of resourceSet#1, resource#3 of resourceSet#2, and resource#3 of resourceSet#3.

[0145] Example 3: RSRP0 reported by the terminal device is the average value or the sum of the RSRPs corresponding to the four pilot resources resource#0, resource#1, resource#2, and resource#3 of resourceSet#0; RSRP1 is the average value or the sum of the RSRPs corresponding to the four pilot resources resource#0, resource#1, resource#2, and resource#3 of resourceSet#1; RSRP2 is the average value or the sum of the RSRPs corresponding to the four pilot resources resource#0, resource#1, resource#2, and resource#3 of resourceSet#2; RSRP3 is the average value or the sum of the RSRPs corresponding to the four pilot resources resource#0, resource#1, resource#2, and resource#3 of resourceSet#3.

[0146] As another example, when the pilot grouping is pilot port grouping, the measurement value of the pilot grouping is the measurement value of the pilot resource, and the terminal device reports the measurement value of at least one pilot grouping to the network device.

[0147] Taking the network device configuring four pilot resources resource#0, resource#1, resource#2, and resource#3 for the terminal device as an example, where each pilot resource includes four pilot ports port#0, port#1, port#2, and port#3, the specific examples are similar to the above Examples 1, 2, and 3 and will not be elaborated here.

[0148] Among them, the index value is used to represent the pilot resource or pilot port associated with the measurement value.

[0149] For example, when the pilot grouping corresponds to multiple pilot resources, the index value can represent the set of pilot resources or the pilot resource associated with the measurement value; when the pilot grouping corresponds to multiple pilot resources, the index value can represent the pilot resource or the pilot port associated with the measurement value.

[0150] In a possible implementation, the index value is associated with the measurement value of the pilot grouping, each index value is associated with one or more measurement values, or multiple index values are associated with one measurement value.

[0151] For example, taking Example 1 in the above embodiments as an example, as shown in Table 1, the Channel State Information Reference Signal Resource Indicator (CSI-RS resource indicator, CRI) is an index value, and one index value is associated with multiple measurement values. When CRI is 0, it identifies four measurement values: RSRP0, RSRP1, RSRP2, and RSRP3.

[0152] Table 1

[0153]

[0154] For example, taking Example 2 in the above embodiments as an example, as shown in Table 2, one index value is associated with one measurement value. When CRI is 0, it identifies RSRP0; when CRI is 1, it identifies RSRP1; when CRI is 2, it identifies RSRP2; when CRI is 3, it identifies RSRP3. Alternatively, the index value is related to the number of the pilot resource. As shown in Table 3, when CRI is N0, the corresponding RSRP is the RSPR corresponding to resource#N0 of resourceSet#0; when CRI is N1, the corresponding RSRP is the RSPR corresponding to resource#N1 of resourceSet#1, and so on. Among them, the values of N0, N1, N2, and N3 can be the same or different.

[0155] Table 2

[0156] CRI RSRP 0 RSRP0 (resourceSet#0 - resource#0 + resourceSet#1 - resource#0 + …) 1 RSRP1 (resourceSet#0 - resource#1 + resourceSet#1 - resource#1 + …) 2 RSRP2 (resourceSet#0 - resource#2 + resourceSet#1 - resource#2 + …) 3 RSRP3 (resourceSet#0 - resource#3 + resourceSet#1 - resource#3 + …)

[0157] Table 3

[0158] CRI RSRP N0 RSRP0 (resourceSet#0 - resource#N0) N1 RSRP1 (resourceSet#0 - resource#N1) N2 RSRP2 (resourceSet#0 - resource#N2) N3 RSRP3 (resourceSet#0 - resource#N3)

[0159] For example, taking Example 3 in the above embodiments as an example, multiple index values are related to the numbers of the pilot resources in the pilot resource set. As shown in Table 4, when CRI is 0, 1, 2, or 3, then RSRP0 is the average value or the sum (taking the sum as an example in Table 4) of the RSRPs corresponding to resource#0, resource#1, resource#2, and resource#3 in resourceSet#0 respectively.

[0160] Table 4

[0161]

[0162] In this application, the network device sends multiple pilot packets to the terminal device. Different pilot packets correspond to different analog beams, and each pilot packet in the multiple pilot packets corresponds to multiple pilot resources or multiple pilot ports. The terminal device calculates the measurement value of each pilot packet according to the multiple pilot packets. The terminal device then reports the measurement value corresponding to at least one pilot packet to the network device. Since the analog beams of different pilot packets are different, the measurement and reporting of different analog beams can be realized, so as to realize the perception of different analog beams by the terminal device and improve the communication performance of the multi-user system.

[0163] Step 304: The network device sends the spatial domain reception indication information of the downlink signal to the terminal device according to the measurement value corresponding to at least one pilot packet reported by the terminal device. Correspondingly, the terminal device receives the spatial domain reception indication information of the downlink signal from the network device.

[0164] Among them, the spatial domain reception indication information is used to indicate the reception beam reference for the terminal device to receive the downlink signal.

[0165] As an example, the network device sends TCI information to the terminal device according to the measurement value corresponding to each pilot packet. The TCI information is associated with the identification information of the pilot packet. The terminal device determines the reception beam of the terminal device based on the TCI information. Specifically, different reception beams are maintained for different analog beams, and the same reception beam is maintained for the same analog beam and different digital beams. Among them, the identification information of the pilot packet associated with the TCI can be the identification information of the pilot resource set (for example, resourceSet#0), or the identification information of the pilot resource (for example, resource#1), or the identification information of the pilot port (for example, port#2).

[0166] In a possible implementation manner, the TCI information is TCI-state. The network device indicates the TCI-state through the TCI field in the downlink control information (DCI).

[0167] For example, the size of the TCI field is 3 bits (bit), which can specifically represent 8 different field values (codepoint). Each field value corresponds to an index of a TCI-state, and the TCI-state index can uniquely identify a TCI-state.

[0168] In a possible embodiment of this application, the spatial domain reception indication information includes a local index. The local index is used to indicate the pilot packet reported by the terminal device for reference in the spatial domain reception of the downlink signal.

[0169] As an example, when a network device receives measurement values of multiple pilot packets reported by a terminal device and sends spatial reception indication information to the terminal device, the first local index is associated with the first pilot packet reported by the terminal device, the second local index is associated with the second pilot packet reported by the terminal device, and so on. One pilot packet corresponds to one analog beam or multiple digital beams of one analog beam.

[0170] For example, a local index of 0 indicates that the downlink signal reception refers to the first pilot packet reported by the terminal device, and a local index of 1 indicates that the downlink signal reception refers to the second pilot packet reported by the terminal device.

[0171] In a possible embodiment, each TCI-state includes an index (tci-StateId) and two quasi-co-location information (QCL-Info). Each QCL-Info includes a cell field and a partial bandwidth (bandwidth, BWP) identifier, which are used to indicate which BWP in which cell the TCI-state is applied to. The QCL-Info also includes a reference signal, indicating which reference signal resource forms a QCL relationship with. Among them, the QCL relationship means that two reference signal resources have the same spatial parameters. The QCL-Info also includes qcl-Type, which is used to determine the same spatial parameters. The qcl-Type can have four values, namely typeA, typeB, typeC, and typeD. Among them, typeD means that two reference signal resources have the same spatial reception parameter information, that is, two beams have the same reception beam.

[0172] In a possible implementation manner, the specific process by which the network device instructs the terminal device to determine the reception beam through the TCI-state includes the configuration of the TCI-stste, the activation of the TCI-state, and the indication of the TCI-state:

[0173] First, the network device configures 8 TCI-states for the terminal device through radio resource control (RRC) signaling. All 8 TCI-states include a QCL-Info of typeD. It can be understood that the network device can also configure TCI-states that do not include QCL-info of typeD, which is not limited in the embodiments of the present application.

[0174] Secondly, after the network device configures multiple TCI-states, 8 TCI-states are activated through a medium access control-control element (MAC-CE). These 8 TCI-states correspond one-to-one with 8 values of the TCI field in DCI. For example, Figure 4 The figure shows a schematic diagram of the MAC-CE structure for activating TCI-states. Among them, fields T0 to T(N-2)×8+7 respectively correspond to the configured TCIs with indexes from 0 to (N-2)×8+7. The size of each field is 1 bit, and the value of the field is 0 or 1. When the value of the field is 1, it indicates that the TCI-state is activated; when the value of the field is 0, it indicates that the TCI-state is not activated. Each MAC-CE can have 8 active fields with a value of 1, and the rest are all 0. The 8 TCI-states corresponding to the 8 fields with a value of 1 are the 8 TCI-states corresponding to the 8 values of the TCI field in DCI. For example, the minimum value 000 of the TCI field corresponds to the TCI-state with the smallest activated index in the MAC-CE.

[0175] It should be noted that the MAC-CE has other functions besides TCI-state activation, which will not be elaborated here.

[0176] Finally, the network device indicates a specific TCI-state through the TCI field in DCI. For example, when the value of the TCI field in the DCI sent by the network device to the terminal device is 000, it means that the beam adopts the TCI-state corresponding to 000. The reference signal included in the QCL-Info of type D in this TCI-state is the channel state information reference signal (CSI-RS) with index #1, indicating that the beam is the same as the receiving beam corresponding to the CSI-RS with index #1.

[0177] Among them, the receiving beam corresponding to the CSI-RS with index #1 is determined by the terminal device through measurement. Therefore, through the specific value of the TCI field, the terminal device can determine the corresponding receiving beam and thus receive data using the corresponding receiving beam.

[0178] Optionally, during the beam management pilot measurement phase, the terminal device maintains two receiving beams for each analog beam. The first is a common receiving beam, that is, different analog beams use the same receiving beam for reception. The second is a dedicated receiving beam, that is, a corresponding receiving beam is independently maintained for each analog beam, and the receiving beams corresponding to different analog beams may be the same or different.

[0179] In a possible implementation, the network device indicates the receive beam set that the terminal device should adopt based on whether the values of pilot packet information (such as pilot resource set identifier, pilot resource identifier, pilot port identifier, beam index identifier, etc.) are valid. For example, when the pilot packet information associated with TCI has a valid value and the network device configures the pilot packet information containing this value for the terminal device, the dedicated receive beam of this analog beam is adopted. When the pilot packet information associated with TCI has an invalid value, that is, the pilot packet information configured by the network device for the terminal device does not contain this value, the common receive beam is adopted.

[0180] In another possible implementation, the network device configures reservation indication information for the terminal device, and the reservation indication information is used to indicate the type of receive beam adopted by the terminal device. For example, 0 indicates receiving using the common receive beam; 1 indicates receiving using the dedicated receive beam of each analog beam.

[0181] The above embodiments describe, taking downlink transmission as an example, the implementation manner in which the network device configures multiple pilot packets and spatial domain receive indication information for the terminal device. It can be understood that in uplink transmission, the specific implementation manner is similar, where the transmit beam of the uplink transmission is indicated by a spatial relation. Similar to TCI-state, the spatial relation is used to determine the transmit beam adopted by the terminal device.

[0182] In a possible implementation, the network device configures a spatial relation for the terminal device through RRC signaling. The spatial relation includes identification information of the spatial relation, identification information of the cell, pilot resources, path loss measurement reference signals, power control parameters, etc. The pilot resources are used to indicate the corresponding uplink beam. The uplink transmission adopts spatial relation#1, and this spatial relation#1 includes pilot resource#2, indicating that the transmit beam of this uplink transmission is the transmit beam or receive beam of pilot resource#2.

[0183] For example, when the pilot resource is SRS, it indicates that the transmit beam adopted for the uplink transmission is the transmit beam of SRS. Another example is that when the pilot resource is SSB / CSI-RS, it indicates that the transmit beam adopted for the uplink transmission is the receive beam of SSB / CSI-RS.

[0184] It can be understood that the network device can configure multiple spatial relationships for the terminal device, and then activate one of the multiple spatial relationships through MAC-CE for data transmission. For example, the physical uplink control channel (PUCCH), physical uplink shared channel (PUSCH), SRS, etc. included in the uplink transmission all require corresponding spatial relationships. The spatial relationships of PUCCH and SRS are both indicated by MAC-CE signaling, while PUSCH is associated with a specific SRS during transmission and uses the spatial relationship of SRS for transmission.

[0185] The above mainly introduces the solution of the embodiment of the present application from the perspective of the interaction between each network element. It can be understood that each network element, such as a communication device, etc., includes corresponding structures and / or software modules for implementing the above functions. Those skilled in the art should easily realize that, combined with the units and algorithm steps of each example described in the embodiments disclosed herein, the present application can be implemented in the form of hardware or a combination of hardware and computer software. Whether a certain function is executed in the way of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution.

[0186] The embodiment of the present application provides a beam management device, which includes: a transceiver, a memory, a processor, and a computer program stored on the memory and executable on the processor.

It should be noted that some types of terminal devices may not have an input / output device.

[0189] When data needs to be sent, after the processor performs baseband processing on the data to be sent, it outputs a baseband signal to the radio frequency circuit. The radio frequency circuit performs radio frequency processing on the baseband signal and then sends the radio frequency signal outwards in the form of electromagnetic waves through the antenna. When data is sent to the terminal device, the radio frequency circuit receives the radio frequency signal through the antenna, converts the radio frequency signal into a baseband signal, and outputs the baseband signal to the processor. The processor converts the baseband signal into data and processes the data. For the sake of convenience of explanation, Figure 5 only one memory and one processor are shown in the figure.
