Description

Technical Field

[0001] The present application relates to the field of communications, and in particular, to a method and a communication device for reporting beam reports. Background Art

[0002] In the fifth generation (5G) communication system, network equipment (e.g., next generation node B (gNB)) can interact with user equipment (UE) through beamforming technology. By measuring the beam, the UE can report the beam report to the network equipment. In addition, the UE can send a scheduling request (SR) to the network equipment to request uplink transmission resources. However, the current methods of UE reporting beam reports have certain limitations. Therefore, how to enhance the traditional scheduling request (SR) is an urgent problem to be solved. Summary of the invention

[0003] In view of this, the present application provides a method for reporting beam reports, a communication device, a chip system, a computer-readable storage medium, a computer program product and a communication system, so that the network equipment can accurately know the UE's need to send beam reports, thereby improving the reliability of the transmission beam reports.

[0004] In a first aspect, a method for reporting a beam report is provided, which can be performed by a UE, or can be performed by a component configured in the UE (such as a circuit, a chip, or a chip system, etc.), or can be implemented by a logic module or software that can implement all or part of the UE function. This application is not limited to this.

[0005] Specifically, the method includes: the UE sends a first scheduling request SR to a network device, the first SR is used to request reporting of a beam report; the first SR includes one or more of the following: first indication information, priority information of the beam report; the first indication information is used to indicate the request type of the first SR; and reporting the beam report.

[0006] In some embodiments, after the UE sends the first SR, the transmission resources used for reporting the beam report may be preconfigured resources or configured by the network device, and there is no specific limitation on this. For example, after the UE sends the first SR to the network device, it receives the DCI sent by the network device, and the DCI is used to indicate the transmission resources; the UE reports the beam report using the transmission resources indicated by the DCI. For another example, after sending the first SR, the UE reports the beam report after an interval of preset time domain resources.

[0007] Based on the above technical solution, the UE sends a first scheduling request SR to the network device to request to report a beam report, and carries one or more of the following in the first SR: first indication information, priority information of the beam report; so that the network device can accurately know the need of the UE to send a beam report, thereby improving the reliability of the transmission beam report. Compared with the traditional SR that is only used to request uplink scheduling resources, the first SR introduced in the embodiment of the present application supports requesting to upload a beam report, which helps to improve the flexibility and accuracy of beam management.

[0008] It should be noted that the UE reports the beam report in the first mode or the second mode. The first mode refers to a mode in which the UE reports the beam report without relying on the scheduling of the network device, but uses the uplink control information UCI in the pre-configured resources. The second mode refers to a mode in which the UE reports the beam report based on the resources dynamically scheduled by the network device. For example, the first mode is mode B in the 3GPP standard; the second mode is mode A in the 3GPP standard.

[0009] The embodiments of the present application provide solutions for reporting beam reports using the first mode or the second mode.

[0010] In a possible implementation, when the UE reports a beam report in the first mode, the first SR includes at least: the first indication information; the first indication information is used to indicate that the request type of the first SR is the first type, and the first type is an SR for requesting to send a beam report. The first type is an SR type (or enhanced SR) extended by the embodiment of the present application. Therefore, the embodiment of the present application introduces an extended SR type, and the extended SR type supports the UE to request to upload a beam report, which can more accurately reflect the resource requirements of the UE.

[0011] Optionally, the first indication information is encoded using a first number of bits, and the value of the first number of bits is used to indicate the type of the first SR. For example, the first number is 1; the 1-bit encoding scheme can reuse the first PUCCH channel resource (for example, the first PUCCH channel in step 1 in mode B) to save channel overhead.

[0012] Optionally, the first indication information is further used to indicate whether the first SR requests an uplink shared channel resource.

[0013] Optionally, the first indication information is encoded using a second number of bits, and different values ​​of the second number of bits are used to indicate whether the first SR is an SR for sending a beam report, and / or whether the first SR requests an uplink shared channel resource. For example, the second number is 2. Therefore, the flexibility of the first indication information can be enhanced through the second number of bit encoding schemes, thereby indicating more meanings.

[0014] In a possible implementation, before sending the first SR, the method further includes: the UE receives RRC signaling from a network device, and the RRC signaling includes a coding scheme configuration for the first indication information. Therefore, the UE can obtain the coding scheme of the first indication information by receiving the RRC signaling sent by the network device, so that the UE can subsequently use the coding scheme to send the first indication information, and flexibly determine the meaning of the first indication information based on its own needs, thereby indicating the request type of the SR, for example, for requesting uplink resources, or for requesting an upload beam report.

[0015] Exemplarily, the first indication information is a scheduling request beam report indication (SR beam report indicator, SRBRI).

[0016] The following describes a solution for the second mode. In one possible implementation, when the UE reports the beam report using the second mode, the first SR includes at least priority information of the beam report; the method further includes: the UE receives downlink control information DCI from a network device, and the DCI is used to schedule uplink transmission resources for transmitting beam reports based on the priority information; the UE reports the beam report on the uplink transmission resources based on the scheduling of the DCI. Therefore, by adding the priority information of the beam report in the first SR, the network device can allocate transmission resources to the UE according to the priority information, thereby ensuring smooth transmission of high-priority beam reports.

[0017] In a possible implementation, the priority information is encoded using a third number of bits, and different values ​​of the third number of bits are used to indicate different reporting priorities of the beam report. For example, the third number is 2.

[0018] In order to further dynamically guide the network device to dynamically configure appropriate resources for the UE, the embodiment of the present application also proposes to introduce resource indication information in the SR. The first SR also includes resource indication information, and the resource indication information is used to indicate whether uplink shared channel resources are required. Therefore, by adding resource indication information in the first SR, the network device can accurately know the resource requirements of the UE.

[0019] Optionally, the resource indication information is encoded using a fourth number of bits, and different values ​​of the fourth number of bits are used to indicate whether uplink shared channel resources are required. For example, the fourth number is 1. Therefore, by introducing 1 bit of information to indicate resource requirements, it does not occupy too much overhead, which helps to save channel overhead.

[0020] In some application scenarios, the method is applied to a vehicle network communication scenario; the UE is a V2X device. The V2X device sends a first SR to a network device or another V2X device, and the first SR is used to request a beam report; the first SR includes one or more of the following: first indication information, priority information of the beam report; wherein the first indication information is used to indicate the request type of the first SR; the V2X device reports the beam report. Optionally, the request type of the first SR is indicated by the first indication information, and the first indication information occupies a small number of bits (such as 1 bit or 2 bits), which can reduce signaling overhead.

[0021] In some other application scenarios, the method is applied to industrial Internet of Things IIOT or high-reliability and low-latency industrial automation communication scenarios; the UE is an IIOT device; the IIOT device sends a first scheduling request SR to a network device, and the first SR is used to request a beam report; the first SR includes one or more of the following: first indication information, priority information of the beam report; wherein the first indication information is used to indicate the request type of the first SR; the IIOT device reports a beam report. Optionally, the first SR includes priority information of the beam report. Therefore, the IIOT device can ensure the transmission priority of critical signals by sending priority information of the beam report to the network device so that the network device can respond or schedule resources using the priority information.

[0022] In some other application scenarios, the method is applied to intelligent manufacturing scenarios based on a communication network (such as 5G); the UE is a machine device; the machine device sends a first scheduling request SR to a network device or a management device, and the first SR is used to request a beam report; the first SR includes one or more of the following: first indication information, priority information of the beam report; wherein the first indication information is used to indicate the request type of the first SR; the machine device reports a beam report. Through the method of reporting beam reports in the embodiments of the present application, the device or network can accurately understand the needs of the machine device, which helps to optimize the communication scheduling between machine devices in the communication network (such as a 5G network), thereby improving production efficiency.

[0023] It should be understood that in the above-mentioned application scenarios, various specific implementation methods of the first SR can be referred to the previous description. For the sake of brevity, they will not be elaborated here one by one.

[0024] In a second aspect, a method for reporting a beam report is provided, which can be performed by a network device, or can be performed by a component configured in the network device (such as a circuit, a chip, or a chip system, etc.), or can be implemented by a logic module or software that can implement all or part of the network device functions. This application is not limited to this.

[0025] Specifically, the method includes: a network device receives a first scheduling request SR from a UE, the first SR is used to request reporting of a beam report; the first SR includes one or more of the following: first indication information, priority information of the beam report; the first indication information is used to indicate the request type of the first SR; and receives the beam report.

[0026] Based on the above technical solution, the network device can accurately know the need of the UE to send a beam report based on one or more of the following carried in the first SR: first indication information, priority information of the beam report, by receiving the first SR sent by the UE, thereby improving the reliability of the transmission beam report. That is, after receiving the first SR sent by the UE, the network device can identify the request type of the first SR based on the first indication information in the first SR; thereby ensuring that the beam report triggered by the UE through mode B is correctly processed. At the same time, since no new signaling is introduced, additional signaling overhead can be reduced. Compared with the traditional SR that is only used to request uplink scheduling resources, the first SR introduced in the embodiment of the present application supports requesting to upload beam reports, which helps to improve the flexibility and accuracy of beam management.

[0027] In a possible implementation, when the UE adopts the first mode to report the beam report, the first SR includes at least: the first indication information; the first indication information is used to indicate that the request type of the first SR is the first type, and the first type is an SR for requesting to receive the beam report.

[0028] In a possible implementation, the first indication information is encoded using a first number of bits, and the value of the first number of bits is used to indicate the type of the first SR. Therefore, after receiving the first SR sent by the UE, the network device can accurately identify the request type of the first SR based on the value of the first indication information (such as SRBRI) in the first SR, and thus respond to the UE based on the request type, for example, ensuring that the beam report triggered by the UE through mode B is correctly processed.

[0029] In a possible implementation manner, the first indication information is further used to indicate whether the first SR requests an uplink shared channel resource.

[0030] In a possible implementation, the first indication information is encoded using a second number of bits, and different values ​​of the second number of bits are used to indicate whether the first SR is an SR reported by a received beam, and / or whether the first SR requests uplink shared channel resources.

[0031] In a possible implementation, before receiving the first SR, the method further includes: the network device sends RRC signaling to the UE, and the RRC signaling includes a coding scheme configuration of the first indication information. Therefore, the network device configures the coding scheme of the first indication information to the UE in advance, so that the UE can subsequently use the coding scheme to send the first indication information.

[0032] In a possible implementation, when the UE adopts the second mode to report the beam report, the first SR includes at least priority information of the beam report; the method also includes: the network device sends downlink control information DCI, and the DCI is used to schedule uplink transmission resources for transmitting the beam report based on the priority information; and receives the beam report on the uplink transmission resources.

[0033] Optionally, the priority information is encoded using a third number of bits, and different values ​​of the third number of bits are used to indicate different reporting priorities of the beam report.

[0034] In a possible implementation manner, the first SR further includes resource indication information, where the resource indication information is used to indicate whether uplink shared channel resources are needed.

[0035] Optionally, the resource indication information is encoded using a fourth number of bits, and different values ​​of the fourth number of bits are used to indicate whether uplink shared channel resources are needed.

[0036] In some application scenarios, the method is applied to a vehicle networking communication scenario; the network device is a device in the vehicle networking communication scenario; the network device receives a first scheduling request SR from a V2X device, the first SR is used to request a beam report; the first SR includes one or more of the following: first indication information, priority information of the beam report; wherein the first indication information is used to indicate the request type of the first SR; and the beam report reported by the V2X device is received. Based on this, the network device can accurately identify the needs of the V2X device, thereby improving the transmission reliability; further, for scenarios of inter-device communication (such as a V2X device and another V2X device), it also helps to improve the reliability of cooperative communication between vehicles.

[0037] In some other application scenarios, the method is applied to industrial Internet of Things IIOT or high-reliability, low-latency industrial automation communication scenarios; the network device is a network device in the industrial Internet of Things IIOT or high-reliability, low-latency industrial automation communication scenarios; the network device receives a first scheduling request SR sent by the IIOT device, and the first SR is used to request to report a beam report; the first SR includes one or more of the following: first indication information, priority information of the beam report; wherein the first indication information is used to indicate the request type of the first SR; and receives a beam report from the IIOT device. Optionally, the first SR includes priority information of the beam report. Therefore, the network device can ensure the transmission priority of critical signals by obtaining the priority information of the beam report in the first SR and using the priority information for response or resource scheduling.

[0038] In some other application scenarios, the method is applied to a smart manufacturing scenario based on a communication network (such as 5G); the network device is a network device or a management device in a smart manufacturing scenario; the network device receives a first scheduling request SR from a machine device, and the first SR is used to request a beam report; the first SR includes one or more of the following: first indication information, priority information of the beam report; wherein the first indication information is used to indicate the request type of the first SR; and receiving a beam report from the machine device. Through the method for reporting beam reports in the embodiments of the present application, the network can accurately understand the needs of the machine device, which helps to optimize the communication scheduling between machine devices in a communication network (such as a 5G network), thereby improving production efficiency.

[0084] In actual applications, multiple network devices can collaborate to assist the terminal in achieving wireless access, and different network devices can respectively implement part of the functions of the base station. For example, the network device can be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU).

For example, the access network device in the vehicle to everything (V2X) technology can be a road side unit (RSU). Multiple access network devices in the communication system can be base stations of the same type or different types. The base station can communicate with the terminal or communicate with the terminal through a relay station. The terminal can communicate with multiple base stations in different access technologies. The embodiments of the present application do not limit the specific technology and specific device form adopted by the access network device.

[0087] The UE of the embodiment of the present application may also be referred to as: terminal equipment, station, mobile station (MS), mobile terminal (MT), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication equipment, user agent or user device, etc.

[0088] The access network equipment and / or the terminal can be fixed or movable. The access network equipment and / or the terminal can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on the water surface; they can also be deployed on aircraft, balloons and artificial satellites in the air. The embodiments of the present application do not limit the application scenarios of the access network equipment and terminals. The access network equipment and the terminal equipment can be deployed in the same scenario or different scenarios. For example, the access network equipment and the terminal equipment are deployed on land at the same time; or, the access network equipment is deployed on land and the terminal equipment is deployed on the water surface, etc., and examples are not given one by one.

[0089] In the present application, the device for realizing the function of the network device may be a network device, or a device that can support the network device to realize the function, such as a processor, a circuit, a chip, or a chip system, etc. The device can be installed in the network device or connected to the network device for use. For example, the device for realizing the function of the network device may be an access network device, or a module in the access network device (such as a chip, a chip system, or a software module, etc.), or a control subsystem containing the function of the access network device. For example, the control subsystem containing the function of the access network device may be a control center in a scenario where the terminal can be applied, such as a smart grid, industrial control, smart transportation, or a smart city. In the technical solution provided in the present application, the technical solution provided in the present application is described by taking the device for realizing the function of the network device as a network device as an example.

[0090] In the present application, the device for realizing the function of the terminal device may be the terminal device, or may be a device capable of supporting the terminal device to realize the function, such as a processor, a circuit, a chip, or a chip system, etc. The device may be installed in the terminal device or connected to the terminal device for use. In the technical solution provided in the present application, the technical solution provided in the present application is described by taking the terminal device as an example in which the device for realizing the function of the terminal device is the terminal device.

[0091] The communication between the access network device and the terminal device may follow a certain protocol layer structure. Exemplarily, the protocol layer structure may include a control plane protocol layer structure and a user plane protocol layer structure. For example, the control plane protocol layer structure may include at least one of the following: a radio resource control (RRC) layer, a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, a media access control (MAC) layer, or a physical (PHY) layer. For example, the user plane protocol layer structure may include at least one of the following: a service data adaptation protocol (SDAP) layer, a PDCP layer, an RLC layer, a MAC layer, or a physical layer.

[0092] Figure 2 FIG. 1 is a schematic diagram of the structure of an access network device. As an implementation example, Figure 2 As shown, the access network device may include at least one CU and at least one DU. This design may be referred to as CU and DU separation. A CU may be connected to one or more DUs. CU and DU may be divided according to the protocol layers of the wireless network: for example, the functions of the PDCP layer and the protocol layers above (such as the RRC layer and the SDAP layer, etc.) are set in the CU, and the functions of the protocol layers below the PDCP layer (such as the RLC layer, the MAC layer and the PHY layer, etc.) are set in the DU; for another example, the functions of the protocol layers above the PDCP layer are set in the CU, and the functions of the protocol layers below the PDCP layer are set in the DU, without limitation. When the CU includes a CU-CP and a CU-UP, the CU-CP is used to implement the control plane function of the CU, and the CU-UP is used to implement the user plane function of the CU. For example, when the CU is configured to implement the functions of the PDCP layer, the RRC layer and the SDAP layer, the CU-CP is used to implement the RRC layer function and the control plane function of the PDCP layer, and the CU-UP is used to implement the SDAP layer function and the user plane function of the PDCP layer. This application does not limit the names of CU and DU. The above division of the processing functions of the CU and DU according to the protocol layer is only an example, and may also be divided in other ways.

[0093] The CU may be connected to the core network. Optionally, the CU may have some functions of the core network.

[0094] Furthermore, some functions of DU can be separated and set. Figure 2As shown, this part of the functions can be implemented by a radio unit (RU). The RU can have a radio frequency function. The present application does not limit the name of the RU. The DU and the RU can be split or separated at the PHY layer. For example, the DU can implement the high-level functions in the PHY layer, and the RU can implement the low-level functions in the PHY layer or implement the low-level functions and the radio frequency functions. The high-level functions in the PHY layer include functions that are closer to the MAC layer, and the low-level functions in the PHY layer include functions that are closer to the radio frequency. For example, the high-level functions of the PHY layer include one or more of the following: forward error correction (FEC) encoding / decoding, scrambling, or modulation / demodulation. The low-level functions of the PHY layer include one or more of the following: fast Fourier transform (FFT) / inverse fast Fourier transform (IFFT), beamforming, or physical random access channel (PRACH) extraction and filtering, etc. The RU can communicate radio frequency signals with the terminal device through the air interface. The pre-coding function of the PHY layer code can be located in the DU or in the RU. The splitting method between DU and RU can be various possible methods without limitation. There is an interface between DU and RU. For example, depending on the splitting method, the interface between DU and RU can be a common public radio interface (CPRI) interface or an enhanced common public radio interface (eCPRI) interface.

[0095] Optionally, any one of the above-mentioned CU, CU-CP, CU-UP, DU and RU can be a software module, a hardware structure, or a software module plus a hardware structure, without limitation. Among them, the existence forms of different entities can be the same or different. For example, CU, CU-CP, CU-UP and DU are software modules, and RU is a hardware structure. For the sake of brevity, all possible combinations are not listed here one by one. These modules and their execution methods are also within the scope of protection of the embodiments of the present application. For example, when the method of the embodiment of the present application is executed by an access network device, it can be specifically executed by at least one of CU, CU-CP, CU-UP, DU, or RU.

[0096] In order to facilitate understanding by those skilled in the art, the terms or related technologies that may be involved in the embodiments of the present application are explained below. For example, the description of some terms or technologies can also refer to the description in the 3rd Generation Partnership Project (3GPP) standard protocol.

[0097] Beam: A beam is a communication resource. A beam can be a wide beam, a narrow beam, or other types of beams. The technology for forming a beam can be beamforming technology or other technical means. Beamforming technology can be specifically digital beamforming technology, analog beamforming technology, and hybrid digital / analog beamforming technology. Different beams can be considered as different resources. The same information or different information can be sent through different beams. Optionally, multiple beams with the same or similar communication characteristics can be regarded as a beam. A beam can include one or more antenna ports for transmitting data channels, control channels, and detection signals. For example, a transmit beam can refer to the distribution of signal strength formed in different directions in space after the signal is transmitted by the antenna, and a receive beam can refer to the distribution of signal strength of wireless signals received from the antenna in different directions in space. It can be understood that one or more antenna ports that form a beam can also be regarded as an antenna port set.

[0098] Beam reporting: refers to the process of UE reporting beam quality and beam decision results to network equipment (such as RAN). Beam determination refers to the measurement results obtained through beam measurement, such as selecting one or more beams with better beam quality from multiple beams. Beam measurement refers to the evaluation of the quality of the received signal by the communication device.

[0099] Beam quality: can be measured by reference signal received power (RSRP), block error rate (BLER), reference signal received quality (RSRQ), reference signal received strength indicator (RSSI), signal to interference and noise ratio (SINR), signal to noise ratio (SNR), channel quality indicator (CQI), correlation and other metrics. It should be understood that the beam quality metric is not limited in the embodiments of the present application.

[0100] The embodiment of the present application does not specifically limit the triggering event (EVENT) of the beam report. For example, the triggering event of the beam report is a triggering event defined in 3GPP.

[0101] Exemplarily, the triggering event of the beam report includes the following: Event 1: the quality of the current beam is worse than a certain threshold; Event 2: the quality of at least one new beam (such as L1-RSRP value) is higher than a certain threshold of the quality of the current beam; Event 7: The quality (e.g., L1-RSRP value) of at least one new beam is higher than a certain threshold value of the quality of a reference signal (RS); the reference signal is an RS derived from an activated transmission configuration indicator (TCI) state with the Mth best quality. The activated TCI state with the Mth best quality is determined based on a beam pool; the multiple beams included in the beam pool are sorted in order from best to worst according to beam quality.

[0102] It should be understood that the values ​​of the thresholds involved in the above-mentioned events, or the quantitative indicators of the signal quality, can refer to the description in the protocol, or can be set based on the actual application scenario, and the embodiments of the present application do not specifically limit this.

[0103] The UE supports the following two modes for transmission of beam reports. Figure 3A and Figure 3B Describe them separately.

[0104] refer to Figure 3A , Figure 3A FIG. 4 shows an example flow chart of a UE reporting a beam report based on mode A. Figure 3A As shown, it includes the following three steps: Step 1: The UE sends a first physical uplink control channel (PUCCH) to a network device. Correspondingly, the network device receives the first PUCCH. The first PUCCH is used to request a beam report to be carried by resources of a second uplink (UL) channel.

[0105] For example, the first PUCCH occupies 1 bit. The first PUCCH includes a scheduling request SR, and the SR is used to request the second UL channel resource to transmit the beam report.

[0106] Step 2: The network device sends downlink control information (DCI) to the UE. Correspondingly, the UE receives the DCI. The DCI is used to indicate the second UL channel resource.

[0107] After receiving the DCI, the UE detects the DCI format to obtain the resources used to transmit the beam report, such as the second uplink channel resources.

[0108] Step 3: The UE reports a beam report through the second UL channel. Correspondingly, the network device receives the beam report sent by the UE through the second UL channel.

[0109] For example, the second UL channel is a physical uplink shared channel (PUSCH).

[0110] In mode A, the network device dynamically schedules uplink control information (UCI) to implement the reporting of beam reports. However, since the urgency and / or resource requirements of each beam report may be different, the traditional SR mechanism cannot effectively guide the network device to dynamically configure resources (for example, the second uplink channel resources). Therefore, it is urgent to propose a method that can dynamically configure resources to transmit beam reports.

[0111] refer to Figure 3B , Figure 3B FIG. 4 shows an example flow chart of a UE reporting a beam report based on mode B. Figure 3B As shown, it includes the following two steps: Step 1: The UE sends a first PUCCH to a network device. Correspondingly, the network device receives the first PUCCH.

[0112] For example, the first PUCCH occupies 1 bit. The first PUCCH includes a scheduling request SR, and the SR is used to notify the network device to transmit a beam report through the second UL channel resource.

[0113] Step 2: The UE reports a beam report through the second UL channel. Correspondingly, the network device receives the beam report sent by the UE through the second UL channel.

[0114] Optionally, a fixed time domain resource is provided between the UE executing step 1 and the UE executing step 2. For example, the UE executes step 2 a plurality of time slots after executing step 1.

[0115] In step 2 of mode B, the UE uses the uplink control information UCI in the pre-configured resources of the second UL channel to report the beam report. That is, the UE does not rely on the scheduling resources of the network device to transmit the beam report. However, since the traditional SR is currently used to request uplink resources, if the traditional SR is used to upload the beam report, it will cause a conflict in the SR function, making it impossible for the network device to accurately know the SR request, thereby affecting the reliability of the transmission beam report.

[0116] For example, the explanations of the above-mentioned mode A and mode B may also refer to the description in the 3GPP standard protocol.

[0117] As can be seen from the above, there are certain limitations in reporting beam reports based on mode A or mode B. Currently, there is no optimization solution for reporting beam reports through scheduling requests SR in the above mode A or mode B.

[0118] In view of this, an embodiment of the present application provides a method for reporting a beam report, wherein the UE sends a first SR, where the first SR is used to request reporting a beam report, and transmits the beam report based on the first SR, thereby improving the transmission reliability of the beam report.

[0119] The scheme provided by the present application is described in detail below in conjunction with the corresponding flowchart. It can be understood that the schematic flowchart provided by the present application mainly uses different devices (such as UE or network devices) as the execution subject of the interactive schematic to illustrate the method, but the present application does not limit the execution subject of the interactive schematic. For example, the device (such as UE or network device) in the schematic flowchart can also be a chip, a chip system, or a processor that supports the device to implement the method, or a logic module or software that can implement all or part of the functions of the device.

[0120] Here, a unified explanation is given. In the interaction process of the embodiment of the present application, the message or signaling interaction involved can adopt the message or signaling in the standard, or it can be a newly introduced message or signaling, and the embodiment of the present application does not make specific limitations on this.

[0121] Figure 4 This is an example flow chart of a method for reporting a beam report in an embodiment of the present application. It can be understood that Figure 4 The UE in can be Figure 1 The UE in the UE may also refer to a device in the UE (such as a processor, chip, or chip system). The network device may be Figure 1 or Figure 2 The network device in the network device may also refer to a device in the network device (such as a processor, chip, or chip system, etc.). Figure 4 As shown, the method includes: Step 401: The UE sends a first SR to a network device. Correspondingly, the network device receives the first SR. The first SR is used to request a beam report.

[0122] The first SR includes one or more of the following: first indication information, priority information of beam report; the first indication information is used to indicate the request type of the first SR.

[0123] Optionally, the first SR includes at least first indication information. The first indication information is used to indicate the request type of the first SR. Exemplarily, by introducing 1-bit indication information, different values ​​of the 1-bit represent different meanings. The first SR can be a traditional SR, that is, an SR for requesting uplink channel resources, or an SR for requesting an upload beam report, that is, an extended SR (or enhanced SR) of the present application.

[0124] Exemplarily, when the UE sends a beam report through mode B, the UE sends the first SR carrying the first indication information. For the network device, when receiving the first SR, the request type of the first SR is identified according to the first indication information included in the first SR, thereby accurately identifying the UE request, so that the beam report is correctly processed; and the overhead of additional signaling can also be reduced.

[0125] Optionally, the first SR indicates priority information of the beam report. The priority information of the beam report may indicate the urgency of the beam report, and may implicitly indicate whether the first SR is a traditional SR or an SR for requesting to upload a beam report. Exemplarily, by extending the additional information of the SR, the SR load can carry more UCI.

[0126] Exemplarily, when the UE sends a beam report through mode A, the UE sends the first SR carrying the priority information. For the network device, when the first SR is received, the urgency of the first SR is identified according to the priority information included in the first SR, thereby accurately identifying the UE needs, so that the beam report is correctly processed; and the overhead of additional signaling can also be reduced.

[0127] For example, if the priority information of the beam report indicates non-priority, it means that the first SR is a traditional SR, so the network device can process it according to the traditional SR after receiving the first SR; if the priority information of the beam report indicates the first priority, it means that the first SR is an enhanced SR, that is, an SR requesting the transmission of a beam report, so the network device can know that the UE requests the transmission of a beam report. In the case where the first SR is an enhanced SR, if the UE uses mode B to transmit the beam report, the network device receives the beam report reported by the UE after several time domain resources; if the UE uses mode A to transmit the beam report, the network device sends DCI to the UE after receiving the first SR. The DCI is used to schedule uplink transmission resources so that the UE uses uplink transmission resources to report the beam report.

[0128] It should be understood that the above content included in the first SR is only an exemplary description, and the embodiments of the present application are not limited to this. In fact, the first SR may also include other information elements for indicating whether to request the transmission of the beam report, or the first SR may include a greater or lesser number of information elements. Exemplarily, the first SR includes both the first indication information and the priority information of the beam report.

[0129] It should be noted that step 410 may be step 1 in the aforementioned mode A or step 1 in mode B, and is not specifically limited thereto. Exemplarily, the first SR is carried in the aforementioned first PUCCH.

[0130] Step 402: The UE reports a beam report. Correspondingly, the network device receives the beam report reported by the UE.

[0131] In some embodiments, after the UE sends the first SR, the transmission resources used for reporting the beam report may be pre-configured resources or configured by the network device, without specific limitation. That is, after the UE sends the first SR, it may not need a reply or response from the network device, but instead reports the beam report after the preset time domain resources, or reports the beam report using pre-configured resources. Alternatively, after the UE sends the first SR, it may receive the transmission resources sent by the network device, and then use the transmission resources to send the beam report.

[0132] For example, after sending the first SR to the network device, the UE receives the DCI sent by the network device, where the DCI is used to indicate transmission resources; the UE uses the transmission resources indicated by the DCI to report a beam report. For another example, after sending the first SR, the UE reports a beam report after an interval of preset time domain resources. The embodiment of the present application does not specifically limit the mode adopted by the UE to report a beam report. Optionally, the UE adopts the first mode or the second mode to report a beam report.

[0133] It should be understood that the embodiments of the present application do not specifically limit the triggering conditions or events for reporting the beam report, and reference may be made to the description in the relevant technology. In other words, no matter what method is used to trigger the reporting of the beam report, the method of the embodiments of the present application is applicable.

[0134] Optionally, the first mode refers to a mode in which the UE does not rely on the scheduling of the network device, but uses the uplink control information UCI in the pre-configured resources to report the beam report. For example, the first mode is mode B in the 3GPP standard. For a detailed description of mode B, please refer to the previous article Figure 3B For the sake of brevity, the explanation is not repeated here.

[0135] Optionally, the second mode refers to a mode in which the UE reports a beam report based on resources dynamically scheduled by the network device. For example, the second mode is mode A in the 3GPP standard. For a detailed description of mode A, please refer to the previous article. Figure 3A For the sake of brevity, the explanation is not repeated here.

[0136] Exemplarily, step 420 may be step 3 in the aforementioned mode A, or may be step 2 in mode B. The beam report is carried in the aforementioned second UL channel.

[0137] In an embodiment of the present application, the UE sends a first scheduling request SR to the network device to request to report a beam report, and the first SR carries one or more of the following: first indication information, priority information of the beam report; so that the network device can accurately know the need of the UE to send a beam report, thereby improving the reliability of the transmission beam report. Compared with the traditional SR which is only used to request uplink scheduling resources, the first SR introduced in the embodiment of the present application supports requesting to upload a beam report, which helps to improve the flexibility and accuracy of beam management.

[0138] The embodiments of the present application provide solutions for using the first mode or the second mode to report beam reports. Figure 5 and Figure 6 Describe them separately.

[0139] In a possible embodiment, when the UE reports a beam report in the first mode, the first SR includes at least first indication information.

[0140] Taking the first mode as mode B as an example, for ease of understanding, we introduce Figure 5 The method flow of the UE using mode B to transmit beam report in the embodiment of the present application is described. Figure 5 As shown, at least the following steps are included: Step 501: UE sends a first PUCCH to a network device. Correspondingly, the network device receives the first PUCCH. The first PUCCH includes a first SR, and the first SR includes first indication information.

[0141] For the description of the first SR, please refer to the previous text, which will not be repeated here for the sake of brevity.

[0142] Optionally, the first indication information is used to indicate that the request type of the first SR is a first type, and the first type is an SR used to request to send a beam report. The first type is an SR type (or enhanced SR) extended in an embodiment of the present application. By extending the SR type, the extended SR type supports the UE to request to upload a beam report, which can more accurately reflect the resource requirements of the UE.

[0143] It should be noted that the first indication information may adopt different coding schemes to indicate different meanings. Optionally, the first indication information occupies a certain number of bits, and different values ​​of the certain number of bits are used to characterize the type of SR, and / or to characterize other requirements such as whether to request uplink shared channel resources. For example, the first indication information is encoded using 1 bit, and different values ​​of the 1 bit represent different SR types. For another example, the first indication information is encoded using 2 bits, and the different values ​​of the 2 bits can represent more meanings than 1 bit. Regarding the coding scheme of the first indication information, it can be predefined by the protocol or configured by the network device to the UE, and there is no specific limitation on this. This will be explained later in conjunction with the examples in Table 1 and Table 2.

[0144] For unified explanation here, the specific implementation methods of "predefined" may include any of the following: predefined by the protocol, or specified by the manufacturer of the communication equipment, defined by the communication operator, preset in the communication equipment when it leaves the factory, or agreed in advance by other agreed methods.

[0145] Step 502: The UE sends a second UL channel to the network device. Correspondingly, the network device receives the second UL channel, wherein the second UL channel includes a beam report.

[0146] For the execution sequence between step 501 and step 502, please refer to the previous text. Figure 3B For the sake of brevity, the description will not be elaborated here.

[0147] Optionally, before the UE sends the first SR (or before step 501), the method further includes: step 500, the network device sends an RRC signaling to the UE. Correspondingly, the UE receives the RRC signaling. The RRC signaling includes a coding scheme configuration of the first indication information.

[0148] Optionally, the encoding scheme configuration of the first indication information includes the number of bits occupied by the first indication information and / or the meaning corresponding to the value of the bit.

[0149] Exemplarily, the RRC signaling includes a scheduling request beam report indicator (SR beam report indicator, SRBRI). By introducing SRBRI, it is used to distinguish between traditional SR and enhanced SR. That is, the network device informs the UE of the relevant reporting information of the beam report indicator through the information element (IE) SRBRI included in the RRC signaling.

[0150] That is to say, the network device can configure the coding scheme of the first indication information to the UE in advance, so that the UE can subsequently use the coding scheme to send the first indication information, and flexibly determine the meaning of the first indication information based on its own needs, and then indicate the request type of the SR, for example, for requesting uplink resources, or for requesting to upload a beam report. After receiving the first SR sent by the UE, the network device can identify the request type of the first SR based on the first indication information in the first SR, and can distinguish whether the SR is used to request uplink resources or to request to report a beam report, which helps to reduce scheduling uncertainty; thereby ensuring that the beam report triggered by the UE (for example, a beam report triggered by mode B; or, a beam report triggered by beam A) is correctly processed. That is, no matter what mode the UE uses to report the beam report, as long as the first SR carries the above-mentioned first indication information, it can ensure that the beam report triggered by the UE is correctly processed. At the same time, since no new signaling is introduced, additional signaling overhead can be reduced.

[0151] The embodiment of the present application does not limit the specific encoding scheme of the first indication information. Optionally, in one implementation, the first indication information is encoded using a first number of bits, and the value of the first number of bits is used to indicate the type of the first SR.

[0152] The embodiment of the present application does not specifically limit the value of the first number. Exemplarily, the value of the first number is 1, that is, the type indication of the SR is implemented by a 1-bit coding scheme. By adopting a 1-bit coding scheme to indicate the SR type, the purpose of indicating the SR type can be achieved without occupying too many bits, which can save the number of bits. The 1-bit coding scheme is described in conjunction with the example in Table 1 below.

[0153] Table 1

[0154] In the above Table 1, SRBRI occupies 1 bit. When the SRBRI value is 0, it means that the SR is used to request uplink shared channel resources (such as PUSCH), that is, the first SR is a traditional SR; when the SRBRI value is 1, it means that the SR is used to request to send a beam report, that is, the first SR is an extended SR. It should be understood that the meanings represented by the various values ​​​​in the examples in Table 1 are only exemplary descriptions, and the embodiments of the present application are not limited to this.

[0155] The above 1-bit coding scheme can reuse the first PUCCH channel resource (ie, the first PUCCH channel in step 1 in the above-mentioned mode B) to save channel overhead.

[0156] Therefore, after receiving the first SR sent by the UE, the network device can accurately identify the request type of the first SR based on the value of SRBRI in the first SR, and thus respond to the UE based on the request type, for example, ensuring that the beam report triggered by the UE through mode B is correctly processed.

[0157] The first indication information implements the indication of the SR request type through a 1-bit coding scheme. In order to further enhance the flexibility of the first indication information, the present application also provides another coding scheme. Optionally, the first indication information is also used to indicate whether the first SR requests an uplink shared channel resource.

[0158] Optionally, the first indication information is encoded using a second number of bits, and different values ​​of the second number of bits are used to indicate whether the first SR is an SR for sending a beam report, and / or whether the first SR requests uplink shared channel resources.

[0159] Exemplarily, the second quantity is 2. That is, the first indication information includes two bits, representing SR and SRBRI respectively. There are four possible values ​​for the two bits, representing different meanings, so that the UE can clearly express whether to send only beam reports, or whether additional uplink shared channel resources are required, thereby improving the flexibility of the first indication information. As shown in Table 2 below: Table 2

[0160] In the above Table 2, taking 01 as an example, it means that the UE requests to send a beam report, but does not request additional uplink shared channel resources. When the value of the 2-bit is 11, it means that the UE not only requests to send a beam report, but also requests additional uplink shared channel resources; the case where the value of the 2-bit is 11 is applicable to the scenario where the UE sends multiple beam reports, that is, multiple beam reports require more uplink shared channel resources to be transmitted. Of course, if the UE is sufficient to send a beam report through the aforementioned second UL channel resources, there is no need to request additional uplink shared channel resources.

[0161] It should be understood that the meanings represented by the various values ​​in Table 2 above are only exemplary descriptions, and the embodiments of the present application are not limited thereto. In fact, the meanings represented by the above values ​​may have other possibilities. It should also be understood that the encoding schemes shown above (such as Table 1 or Table 2) may be pre-configured by the network device or pre-defined by the protocol, and no specific limitation is made to this.

[0162] Therefore, after receiving the first SR sent by the UE, the network device can accurately identify the request type of the first SR based on the value of the SRBRI in the first SR, and respond to the UE based on the request type, for example, ensuring that the beam report triggered by the UE through mode B is correctly processed. In addition, based on the encoding method of the second number, more information about the UE behavior can be obtained, which helps to more accurately identify the needs of the UE so as to make a corresponding response.

[0163] For example, the various implementations described in the above possible embodiments can be understood as adopting the first mode (such as the aforementioned Figure 3B An improved scheme for reporting beam reports in mode B) is shown in FIG.

[0164] In the above possible embodiments, by introducing the first indication information in the first SR, the conflict problem of the traditional SR function mentioned above is solved, so that the network device can clearly know the scheduling request SR sent by the UE, thereby improving the transmission reliability of the beam report.

[0165] In another possible embodiment, when the UE adopts the second mode to report the beam report, the first SR includes at least priority information of the beam report.

[0166] Taking the second mode as mode A as an example, for ease of understanding, we introduce Figure 6 The method flow of the UE using mode A to transmit beam report in the embodiment of the present application is described. Figure 6 As shown, at least the following steps are included: Step 601: The UE sends a first PUCCH to a network device. Correspondingly, the network device receives the first PUCCH. The first PUCCH includes a first SR, and the first SR includes priority information of a beam report.

[0167] For the description of the first SR, please refer to the previous text, which will not be repeated here for the sake of brevity.

[0168] The priority information of the beam report is used to characterize the priority of the beam report, or the urgency of the triggering event. For example, if there are multiple UEs requesting to transmit beam reports at the same time, and different beam reports have different priorities, the network device will prioritize the allocation of transmission resources to the UE requesting to transmit a high-priority beam report, thereby ensuring the smooth transmission of the high-priority beam report.

[0169] Mode A relies on the network device to configure resources for the UE to transmit beam reports. Optionally, when the UE reports beam reports in the second mode, the method further includes: step 602, the network device sends downlink control information DCI to the UE. Correspondingly, the UE receives the DCI. The DCI is used to schedule uplink transmission resources based on the priority information (the uplink transmission resources are used for the UE to transmit beam reports).

[0170] Step 603: The UE reports the beam report in the uplink transmission resource based on the scheduling of the DCI.

[0171] That is to say, when the UE adopts mode A to report the beam report, the UE carries the priority information of the beam report through the SR, so that the network equipment can process the UE's request based on the priority information, thereby meeting the UE's business needs.

[0172] The embodiment of the present application does not specifically limit the encoding scheme of the priority information of the beam report. Optionally, the priority information of the beam report is encoded using a third number of bits, and different values ​​of the third number of bits are used to indicate different reporting priorities of the beam report.

[0173] Table 3

[0174] In the above Table 3, a 2-bit coding scheme is adopted, and different values ​​represent different priorities. For example, when the priority information value is 00, it represents non-priority, or traditional SR; for another example, when the priority information value is 01, it represents low priority. Low priority, medium priority and high priority can represent priorities of different urgency. Of course, different priorities can be determined based on beam quality. For example, the worse the beam quality, the higher the reporting priority of the beam report.

[0175] It should be understood that the coding scheme in Table 3 is only an example description, and the embodiments of the present application are not limited thereto. In fact, a greater or lesser number of bits may be used to characterize the priority of the beam report. As shown in Table 4 below: Table 4

[0176] In the above Table 4, 1 bit can be introduced to represent the priority information, which helps to further save the number of bits and is relatively simple to implement. Of course, the coding scheme in Table 4 is applicable to the case where the UE reports a small number of beam reports (for example, one beam report). If the UE needs to report multiple beam reports, the coding scheme in the above Table 3 or a coding scheme with a larger number of bits indicating the priority information can be used to ensure that the beam report with the highest priority is transmitted first.

[0177] In order to further dynamically guide the network device to dynamically configure appropriate resources for the UE, the embodiment of the present application also proposes to introduce resource indication information in the SR. Optionally, the first SR also includes resource indication information, and the resource indication information is used to indicate whether uplink shared channel resources, such as PUSCH resources, are required.

[0178] The embodiment of the present application does not specifically limit the coding scheme of the resource indication information. Optionally, the resource indication information is encoded using a fourth number of bits, and different values ​​of the fourth number of bits are used to indicate whether uplink shared channel resources are required.

[0179] The embodiment of the present application does not specifically limit the value of the fourth number. Exemplarily, the value of the fourth number is 1, that is, a bit is used to indicate whether additional uplink shared channel resources are needed. This is described in conjunction with the example in Table 5 below.

[0180] Table 5

[0181] In the above Table 5, the resource indication information occupies 1 bit. When the resource indication information value is 0, it means that the UE does not need additional uplink shared channel resources; when the resource indication information value is 1, it means that the UE needs additional uplink shared channel resources. It should be understood that the meanings represented by the various values ​​​​in the examples in Table 5 are only exemplary descriptions, and the embodiments of the present application are not limited to this. By introducing 1 bit of resource indication information, it will not occupy too much overhead, which helps to save channel overhead.

[0182] Therefore, after receiving the first SR sent by the UE, the network device can accurately know whether the UE needs uplink shared channel resources based on the value of the resource indication information in the first SR, and then respond to the UE based on the request type, for example, dynamically configuring resources for the UE, ensuring accurate scheduling of the network device, and helping to improve the transmission reliability of the beam report.

[0183] It should be noted that if the UE indicates more information, such as the specific amount of resource requirements, additional bits may be added for indication, which has higher flexibility.

[0184] It should also be noted that the encoding schemes shown above (such as one or more of Table 3, Table 4 and Table 5) may be pre-configured by the network device or pre-defined by the protocol, and there is no specific limitation on this.

[0185] In the second mode, taking Table 3 and Table 4 above as an example, when the first SR includes both the priority information and the resource indication information, it can be understood as an extension of the load information of the traditional SR. For example, 3 bits of information are added to notify the network device of the priority and resource requirements of the beam report, thereby helping to avoid competitive scheduling delays and improve scheduling accuracy and resource utilization. The embodiment of the present application does not specifically limit the location of the added 3 bits of information. Exemplarily, by adding 3 bits of additional information to the load field in the original SR; or, by extending the PUCCHSR load, 3 bits of information are appended to the original PUCCH SR, wherein the SR is transmitted via the PUCCH, and the aforementioned PUCCHSR can be understood as the PUCCH used to transmit the SR.

[0186] Of course, the above description is based on an example that the first SR includes both the priority information and the resource indication information, and the embodiments of the present application are not limited to this. For example, the first SR includes the priority information but does not include the resource indication information. For another example, the first SR includes the resource indication information but does not include the priority information.

[0187] In the above embodiment, by introducing priority information and / or resource indication information in the first SR, the problem that the traditional SR mechanism mentioned above cannot effectively guide the network device to dynamically configure resources is solved, so that the network device can dynamically configure resources based on the urgency and / or resource requirements of the beam report, which helps to improve the reliability of the transmission beam report.

[0188] It should be understood that the foregoing is described separately in the first mode and the second mode. In fact, the embodiments of the present application are not limited to this. In some cases, the first mode and the second mode may not be distinguished, that is, the various implementation methods shown above can be implemented in combination. Or, in some cases, the various implementation methods mentioned above can be applicable to the first mode or the second mode, that is, there is no limit on which implementation method must be implemented in a certain mode. For example, the first SR includes the first indication information and the priority information of the beam report. For another example, the first SR also includes the first indication information, the priority information of the beam report, and the resource indication information. For the implementation methods of each information, please refer to the previous description.

[0189] Here, it is uniformly explained that each coding scheme shown in the embodiment of the present application is an exemplary description, and the embodiment of the present application is not limited thereto. For example, the meaning represented by the value of the bit involved in the above coding scheme may be different from the meaning shown in the above table. For another example, the above coding scheme can be equivalently replaced by other coding schemes.

In addition, the network device can accurately identify the needs of the V2X device based on the first indication information in the first SR reported by the V2X device, thereby improving transmission reliability; further, for scenarios of inter-device communication (such as a V2X device and another V2X device), it also helps to improve the reliability of collaborative communication between vehicles.
