Description

Technical Field

[0001] The present disclosure relates to, but is not limited to, the field of communication technology, and in particular to a beam processing method, apparatus, communication device, and storage medium. Background Art

[0002] The demand for spectrum for mobile communications continues to increase with the development of mobile technology. Low-frequency bands, such as the sub-6 GHz band, are becoming increasingly scarce. Currently, available spectrum resources are expanding to higher frequencies. Currently, 5G millimeter-wave bands are in use from 26.25 GHz to 51.2 GHz, with research underway for bands above 51.2 GHz. For high-frequency applications, continuous, ultra-long bandwidth is a key requirement for increasing channel capacity. Currently, up to 2.16 GHz of continuous bandwidth is being used in unlicensed spectrum applications from 51.2 GHz to 66 GHz.

[0003] High-frequency electromagnetic waves are significantly affected by particles such as rain and dust during their propagation, and this effect becomes more pronounced as the frequency increases. Due to these scattering and refraction effects, electromagnetic waves of different frequencies can experience beam splitting, similar to the rainbow phenomenon, during propagation. This phenomenon is particularly prone to beam splitting in the continuous, wide bandwidths of high-frequency mobile communications applications. This beam splitting prevents beams of different frequencies from converging into the same beamforming direction, reducing the capacity of the communication channel. Summary of the Invention

[0004] The embodiments of the present disclosure disclose a beam processing method, apparatus, communication equipment, and storage medium.

[0005] According to a first aspect of an embodiment of the present disclosure, a beam processing method is provided, which is applied to a UE, including:

[0006] In response to meeting the segmented reporting conditions of the Channel State Information (CSI)-Reference Signal Received Power (RSRP), the measurement results of the CSI-RSRP measured based on the sub-frequency band where the beam is located are reported, wherein the measurement results are used for the base station to determine whether beamforming adjustment is required.

[0007] According to a second aspect of an embodiment of the present disclosure, a beam processing method is provided, which is applied to a base station, including:

[0008] Receiving a CSI-RSRP measurement result based on a beam-based frequency band, wherein the measurement result is reported by the user equipment UE based on the frequency band in which the beam is located after the user equipment UE meets the CSI-RSRP segment reporting condition;

[0009] Based on the measurement results, determine whether beamforming adjustment is needed.

[0010] According to a third aspect of an embodiment of the present disclosure, a beam processing apparatus is provided, applied to a UE, including:

[0011] The first sending module is configured to report the CSI-RSRP measurement result measured based on the sub-frequency band where the beam is located in response to the CSI-RSRP segment reporting condition, wherein the measurement result is used for the base station to determine whether beamforming adjustment is required.

[0012] According to a fourth aspect of an embodiment of the present disclosure, a beam processing device is provided, applied to a base station, including:

[0013] The second receiving module is configured to receive a measurement result of a channel state information-reference signal received power CSI-RSRP measured based on a beam-based sub-frequency band, wherein the measurement result is measured and reported by the user equipment UE based on the sub-frequency band in which the beam is located after the user equipment UE meets the CSI-RSRP segment reporting condition;

[0014] The second processing module is configured to determine whether beamforming adjustment is required based on the measurement result.

[0015] According to a fifth aspect of an embodiment of the present disclosure, a communication device is provided, the communication device including:

[0016] processor;

[0017] a memory for storing processor-executable instructions;

[0018] The processor is configured to implement the beam processing method of any embodiment of the present disclosure when running the executable instructions.

[0019] According to a sixth aspect of an embodiment of the present disclosure, a computer storage medium is provided, wherein the computer storage medium stores a computer executable program, and when the executable program is executed by a processor, the beam processing method of any embodiment is implemented.

[0020] The technical solutions provided by the embodiments of the present disclosure may have the following beneficial effects:

[0021] In an embodiment of the present disclosure, when the UE meets the CSI-RSRP segment reporting conditions, it reports the CSI-RSRP measurement results based on the sub-frequency band where the beam is located. In this way, the base station can determine whether beamforming adjustment is required based on the measurement results of the sub-frequency band measurement. In this way, in an embodiment of the present disclosure, the situation where the beam cannot be concentrated due to beam splitting can be reduced. For example, the situation where the beam cannot be concentrated due to beam splitting in the high frequency band bandwidth where the beam is located can be reduced, and the directional gain of the entire frequency band where the beam is located is improved, thereby improving the quality of the communication connection between the UE and the base station, thereby improving the communication quality between the UE and the base station.

[0039] Please refer to Figure 1 , which shows a schematic structural diagram of a wireless communication system provided by an embodiment of the present disclosure. Figure 1 As shown, the wireless communication system is a communication system based on cellular mobile communication technology, and the wireless communication system may include: several user equipments 110 and several base stations 120.

[0040] The user equipment 110 may be a device that provides voice and / or data connectivity to a user. The user equipment 110 may communicate with one or more core networks via a radio access network (RAN). The user equipment 110 may be an Internet of Things user device, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an Internet of Things user device. For example, the user equipment 110 may be a fixed, portable, pocket-sized, handheld, computer-built-in, or vehicle-mounted device. For example, a station (STA), subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device, or user equipment. Alternatively, the user equipment 110 may be a device on an unmanned aerial vehicle. Alternatively, the user equipment 110 may be an in-vehicle device, such as a vehicle-mounted computer with wireless communication capabilities, or a wireless user device connected to an external vehicle-mounted computer. Alternatively, the user equipment 110 may also be a roadside device, for example, a street lamp, a traffic light, or other roadside device with a wireless communication function.

[0041] The base station 120 may be a network-side device in a wireless communication system. The wireless communication system may be a fourth-generation mobile communication technology (4G) system, also known as a long-term evolution (LTE) system; or, the wireless communication system may be a 5G system, also known as a new air interface system or a 5G NR system. Alternatively, the wireless communication system may be a next-generation system of the 5G system. The access network in the 5G system may be referred to as a new generation radio access network (NG-RAN).

[0042] Among them, the base station 120 can be an evolved base station (eNB) adopted in a 4G system. Alternatively, the base station 120 can also be a base station (gNB) adopting a centralized distributed architecture in a 5G system. When the base station 120 adopts a centralized distributed architecture, it usually includes a centralized unit (CU) and at least two distributed units (DU). The centralized unit is provided with a protocol stack of a packet data convergence protocol (PDCP) layer, a radio link layer control protocol (RLC) layer, and a medium access control (MAC) layer; the distributed unit is provided with a physical (PHY) layer protocol stack. The embodiment of the present disclosure does not limit the specific implementation method of the base station 120.

[0043] A wireless connection can be established between the base station 120 and the user equipment 110 via a wireless air interface. In various implementations, the wireless air interface is a wireless air interface based on the fourth generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth generation mobile communication network technology (5G) standard, for example, the wireless air interface is a new air interface; or, the wireless air interface can also be a wireless air interface based on the next generation mobile communication network technology standard of 5G.

[0044] In some embodiments, E2E (End to End) connections may also be established between user devices 110. For example, vehicle-to-vehicle (V2V) communication, vehicle-to-infrastructure (V2I) communication, and vehicle-to-pedestrian (V2P) communication in vehicle-to-everything (V2X) communication scenarios.

[0045] Here, the above user equipment can be considered as the terminal equipment in the following embodiments.

[0046] In some embodiments, the wireless communication system may further include a network management device 130 .

[0047] Several base stations 120 are respectively connected to a network management device 130. The network management device 130 may be a core network device in a wireless communication system. For example, the network management device 130 may be a mobility management entity (MME) in an evolved packet core (EPC). Alternatively, the network management device may be other core network devices, such as a serving gateway (SGW), a public data network gateway (PGW), a policy and charging rules function (PCRF), or a home subscriber server (HSS). The embodiments of the present disclosure do not limit the implementation form of the network management device 130.

[0048] In order to better understand the technical solutions described in any embodiment of the present disclosure, first, a partial description of beam communication is given:

[0049] In some embodiments, beam sweeping is performed by evaluating the channel through the base station's channel state information reference signal (CSI-RS) and using multiple beams with different directions to cover the cell. Figure 2 As shown, the base station uses eight beams (e.g., beams t1 through t8) to cover the cell it serves. During downlink transmission, the base station transmits wireless signals using beams with different directional directions (e.g., beams r1 through r4). This process is called beam scanning. In this scenario, the UE measures the wireless signals transmitted by different beams and reports relevant information to the base station. The base station then determines the optimal transmit beam for the UE based on the relevant information reported by the user.

[0050] For example, a portion of CSI-RS resources is used for beam management. The corresponding port resource mapping is configured on the CSI, and the corresponding Channel State Information-Reference Signal Received Power (CSI-RSRP) is measured. Different beams have different directivities and directional gains, and the measured CSI-RSRP is also different. In this way, the base station can select the corresponding beam as the communication beam based on the CSI-RSRP measurement results fed back by the UE.

[0051] However, when the frequency is too high, such as when the continuous frequency of a single carrier is too wide, beam splitting can result in only certain frequencies within a given beam direction meeting the maximum directional gain requirement. Consequently, at other frequencies across the entire continuous bandwidth (excluding the specific frequency), the beam direction may not be properly directed toward the UE and may even deviate significantly, resulting in poor communication connection quality or even disconnection.

[0052] like Figure 3 As shown, an embodiment of the present disclosure provides a beam processing method, applied to a UE, including:

[0053] Step S31: In response to meeting the CSI-RSRP segment reporting condition, reporting the CSI-RSRP measurement result based on the sub-frequency band where the beam is located, wherein the measurement result is used for the base station to determine whether beamforming adjustment is required.

[0054] In some embodiments, the UE may be various mobile terminals or fixed terminals. For example, the UE may be, but is not limited to, a mobile phone, a computer, a server, a wearable device, a game console, or a multimedia device.

[0055] In some embodiments, the base station may be of various types. For example, the base station may be, but is not limited to, a base station of a third-generation mobile communication (3G) network, a base station of a fourth-generation mobile communication (4G) network, a base station of a fifth-generation mobile communication (5G) network, or other evolved base stations. Furthermore, the base station may be a terrestrial network base station or a non-terrestrial network base station.

[0056] In some embodiments, satisfying the segmented CSI-RSRP reporting conditions may include: the UE possessing the segmented CSI-RSRP reporting capability. Here, the UE possessing the segmented CSI-RSRP reporting capability includes: the UE possessing the CSI-RSRP reporting capability for each frequency band, or the UE possessing both the CSI-RSRP measurement capability for each frequency band and the CSI-RSRP reporting capability for each frequency band. Thus, in this embodiment, as long as the UE possesses the segmented CSI-RSRP reporting capability, the CSI-RSRP measurement results for the frequency band in which the beam is located can be reported.

[0057] The UE here has CSI-RSRP frequency band measurement, which can be: during a beam scanning process, the UE's software and hardware support frequency band measurement of the beam.

[0058] The sub-frequency band in which the beam is located here may be a sub-frequency band of the frequency band in which the beam is located. In one embodiment, if the UE supports CSI-RSRP measurement of a sub-frequency band of a beam, it is determined that the UE has the segmented reporting capability of CSI-RSRP.

[0059] In other embodiments, the CSI-RSRP segment reporting condition may be satisfied, for example, if the bandwidth of the frequency band in which the beam resides is greater than or equal to a predetermined bandwidth. For example, if the bandwidth of the frequency band in which the beam resides is greater than or equal to 2 GHz, the CSI-RSRP segment reporting condition is satisfied.

[0060] In yet other embodiments, satisfying the segmented CSI-RSRP reporting conditions may include: requiring segmented reporting of the bandwidth of the frequency band in which the beam resides. For example, if the bandwidth of the frequency band in which the beam resides is greater than or equal to a predetermined bandwidth, it may be considered that the bandwidth of the frequency band in which the beam resides requires segmented reporting. Of course, in other embodiments, requiring segmented reporting of the bandwidth of the frequency band in which the beam resides may be implemented in any other feasible manner, which is not limited herein.

[0061] In yet other embodiments, the conditions for segmented CSI-RSRP reporting may include: the UE possessing segmented CSI-RSRP reporting capability and the bandwidth of the frequency band in which the beam resides being greater than or equal to a predetermined bandwidth. Thus, in this embodiment, the CSI-RSRP measurement results for the sub-frequency bands in which the beam resides are reported only when both the UE possessing segmented CSI-RSRP reporting capability and the bandwidth of the frequency band in which the beam resides requiring segmented reporting are satisfied.

[0062] In one embodiment, the predetermined bandwidth may be the minimum bandwidth of a beam supported by the UE and / or the base station.

[0063] In another embodiment, the predetermined bandwidth may also be any bandwidth greater than the minimum bandwidth of a beam supported by the UE and / or base station. For example, it may be N times the minimum bandwidth of a beam supported by the UE and / or base station, where N is an integer greater than 1.

[0064] The beamforming adjustment here can be any method that can be implemented by the base station; for example, one possible implementation method can be that the base station adjusts the corresponding beam through a delay device; the specific method of beamforming adjustment is not limited here.

[0065] Here, the sub-band of a beam is a portion of the frequency band in which the beam is located. For example, the frequency band in which the beam is located is a total frequency band, and the total frequency band is divided into at least one sub-band. The bandwidth of each sub-band can be the same or different.

[0066] In one embodiment, the measurement result includes: CSI-RSRP.

[0067] In an embodiment of the present disclosure, after the UE meets the CSI-RSRP segment reporting conditions, it reports the measurement results of the CSI-RSRP measured based on the sub-frequency band where the beam is located. In this way, the base station can determine whether beamforming adjustment is required based on the measurement results of the CSI-RSRP measured in the sub-frequency band. In this way, in an embodiment of the present disclosure, the situation where the beam cannot be concentrated due to beam splitting can be reduced, for example, the situation where the beam cannot be concentrated due to beam splitting in a high frequency band bandwidth can be reduced, and the directional gain of the entire frequency band where the beam is located can be increased, thereby improving the quality of the communication connection between the UE and the base station, and further improving the communication quality between the UE and the base station.

[0068] In some embodiments, the measurement result of the CSI-RSRP measured based on the sub-frequency band where the beam is located in the reporting step S31 may be a periodic reporting of the measurement result of the CSI-RSRP measured based on the sub-frequency band where the beam is located, or may be a trigger event-based reporting of the measurement result of the CSI-RSRP measured based on the sub-frequency band where the beam is located. The trigger event here may be that the UE meets the CSI-RSRP segmented reporting conditions, or any other feasible method, which is not limited here. In this way, the embodiment of the present disclosure can realize the determination of whether the base station needs to perform beamforming adjustment in a variety of application scenarios, and thus can solve the problem of beam inability to be concentrated due to beam splitting in more scenarios.

[0069] It should be noted that those skilled in the art will understand that the method provided in the embodiments of the present disclosure may be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0070] like Figure 4 As shown, an embodiment of the present disclosure provides a beam processing method, applied to a UE, including:

[0071] Step S41: obtaining one or more sub-frequency bands of the frequency band where the beam is located;

[0072] Step S42: Perform measurement based on the sub-frequency band to obtain the CSI-RSRP measurement result of the sub-frequency band where the beam is located.

[0073] In some embodiments, when the frequency band where the beam is located is divided into multiple sub-frequency bands, the bandwidths of any two sub-frequency bands may be the same or different. Here, multiple means two or more.

[0074] In one embodiment, the sub-frequency bands are formed by a plurality of continuously distributed frequency points.

[0075] For example, if the bandwidth of the frequency band in which the beam is located is 2 GHz, the 2 GHz frequency band in which the beam is located can be divided into four sub-bands, and the bandwidth of each of the four sub-bands can be 500 MHz, or the bandwidths of the four sub-bands can be 400 MHz, 600 MHz, 600 MHz, and 400 MHz, respectively. For example, if the frequency band in which the beam is located is 0 to 2 GHz, the four sub-bands are 0 to 500 MHz, 500 MHz to 1 GMHZ, 1 GMHZ to 1.5 GMHZ, and 1.5 GHz to 2 GHz, respectively.

[0076] For example, if the bandwidth of the frequency band in which the beam resides is 2 GHz, the 2 GHz frequency band in which the beam resides can be divided into 5 sub-bands, 6 sub-bands, 8 sub-bands, 10 sub-bands, and so on. In this way, in this example, the frequency band in which the beam resides can be divided into any appropriate number of sub-bands. The greater the number of sub-bands divided here, the more CSI-RSRP measurement results obtained, and the more accurately it can be determined whether beamforming adjustment is required.

[0077] For example, if the bandwidth of the frequency band in which the beam resides is less than the predetermined bandwidth, the frequency band in which the beam resides may be divided into a sub-frequency band. If the bandwidth of the frequency band in which the beam resides is greater than the predetermined bandwidth, the frequency band in which the beam resides may be divided into multiple sub-frequency bands. The predetermined frequency band herein may be greater than or equal to the minimum bandwidth of the beam supported by the UE and / or base station.

[0078] In the above step S42, the UE may perform CSI-RSRP measurement based on each sub-frequency band where the beam is located, and obtain the CSI-RSRP measurement result of each sub-frequency band where the beam is located.

[0079] For example, if the frequency band where the beam is located is 2 GHz, and the 2 GHz is divided into 5 sub-bands, the UE can perform CSI-RSRP measurement in the 5 sub-bands respectively to obtain CSI-RSRP measurement results of the 5 sub-bands respectively.

[0080] In the disclosed embodiments, the UE can divide the frequency band in which the beam is located into a certain number of sub-bands, perform CSI-RSRP measurements on each sub-band, and report the measurement results to the base station. In this way, the disclosed embodiments allow the base station to know the CSI-RSRP of each sub-band in which the beam is located, and thus accurately determine whether the base station needs to perform beamforming adjustments based on the measurement results of each sub-band.

[0081] It should be noted that those skilled in the art will understand that the method provided in the embodiments of the present disclosure may be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0082] like Figure 5 As shown, an embodiment of the present disclosure provides a beam processing method, applied to a UE, including:

[0083] Step S51: In response to not meeting the CSI-RSRP segment reporting condition, reporting the CSI-RSRP measurement result measured based on the frequency band where the beam is located.

[0084] In some embodiments, the CSI-RSRP segment reporting conditions are not met, including:

[0085] The UE does not have the capability of reporting CSI-RSRP in segments, and / or the bandwidth of the frequency band where the beam is located is less than or equal to the predetermined bandwidth.

[0086] In other embodiments, failure to meet the segmented CSI-RSRP reporting conditions may include: the frequency band bandwidth of the beam not requiring segmented reporting. For example, if the frequency band bandwidth of the beam is less than or equal to a predetermined bandwidth, it can be considered that the frequency band bandwidth of the beam does not require segmented reporting. Of course, in other embodiments, omitting segmented reporting of the frequency band bandwidth of the beam can be achieved by any other feasible method, which is not a limitation here.

[0087] The CSI-RSRP measurement result measured in the frequency band where the beam is located can be used by the base station to determine whether the beam is used as a beam for communication with the UE.

[0088] In the disclosed embodiments, if the UE does not meet the segmented CSI-RSRP reporting conditions, it can report the CSI-RSRP measurement results measured in the frequency band where the beam is located to the base station. This also enables reporting of the CSI-RSRP measurement results. This disclosed embodiment facilitates subsequent beam management operations such as determining the beam to communicate with the UE based on the CSI-RSRP measurement results, and can also improve the communication quality between the base station and the UE to a certain extent.

[0089] A beam processing method disclosed in an embodiment of the present disclosure may include:

[0090] The measurement is performed based on the frequency band where the beam is located to obtain the CSI-RSRP measurement result of the frequency band where the beam is located.

[0091] If the UE does not meet the conditions for segmented CSI-RSRP reporting, it can perform CSI-RSRP measurement on the frequency band where the beam is located. That is, the frequency band where the beam is located is treated as a total frequency band and CSI-RSRP measurement is performed on this total frequency band. For example, if the bandwidth of the frequency band where the beam is located is 400 MHz, it is determined that the beam does not need segmented reporting and that the UE can perform CSI-RSRP measurement on this 400 MHz frequency band. In this way, the UE can obtain a CSI-RSRP measurement result for the frequency band where the beam is located and report this CSI-RSRP measurement result to the base station.

[0092] In this way, in the embodiment of the present disclosure, when the UE does not meet the CSI-RSRP segment reporting conditions, it can also measure the frequency band where the beam is located, so that the base station can also know the measurement results of the CSI-RSRP in the frequency band where the beam is located, which is beneficial to subsequent beam management operations.

[0093] It should be noted that those skilled in the art will understand that the method provided in the embodiments of the present disclosure may be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0094] It should be noted here that the following beam processing method is applied to a base station and is similar to the description of the beam signal processing method applied to a UE described above. For technical details not disclosed in the embodiment of the beam processing method applied to a base station in this disclosure, please refer to the description of the embodiment of the beam processing method applied to a UE in this disclosure, and no detailed explanation is given here.

[0095] like Figure 6 As shown, an embodiment of the present disclosure provides a beam processing method, applied to a base station, including:

[0096] Step S61: receiving a CSI-RSRP measurement result based on a beam-based frequency band, wherein the measurement result is reported by a user equipment (UE) based on the frequency band in which the beam is located after the user equipment (UE) meets a CSI-RSRP segment reporting condition;

[0097] Step S62: Based on the measurement result, determine whether beamforming adjustment is required.

[0098] In some embodiments, satisfying the CSI-RSRP segment reporting condition may include: the UE having a CSI-RSRP segment reporting capability.

[0099] In other embodiments, satisfying the CSI-RSRP segment reporting condition may include: the bandwidth of the frequency band where the beam is located is greater than or equal to the predetermined bandwidth.

[0100] In some other embodiments, the CSI-RSRP segmented reporting condition may include: the bandwidth of the frequency band where the beam is located needs to be segmented reported. For example, if the bandwidth of the frequency band where the beam is located is greater than or equal to the predetermined bandwidth, it can be considered that the bandwidth of the frequency band where the beam is located needs to be segmented reported.

[0101] In some further embodiments, satisfying the CSI-RSRP segment reporting condition may include: the UE has the CSI-RSRP segment reporting capability and the bandwidth of the frequency band where the beam is located is greater than or equal to the predetermined bandwidth.

[0102] In an embodiment of the present disclosure, a base station receives CSI-RSRP measurement results for each frequency band of a beam transmitted by a UE, and determines whether beamforming adjustment is required based on these measurement results. In this way, the embodiment of the present disclosure can reduce the occurrence of beams that cannot be focused due to beam splitting. For example, it can reduce the occurrence of beams that cannot be focused due to beam splitting in high-band bandwidths, thereby increasing the directional gain of the frequency band in which the beam is located, and thereby improving the communication quality between the UE and the base station.

[0103] It should be noted that those skilled in the art will understand that the method provided in the embodiments of the present disclosure may be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0104] like Figure 7 As shown, an embodiment of the present disclosure provides a beam processing method, applied to a base station, including:

[0105] Step S71: Obtain the CSI-RSRP difference between the measurement results of any two sub-frequency bands;

[0106] Step S72: Determine whether beamforming adjustment is required based on the difference and the threshold.

[0107] In one embodiment, a measurement result of a sub-frequency band measurement includes a CSI-RSRP.

[0108] For example, if the frequency band in which the beam is located is divided into 5 sub-frequency bands, the 5 sub-frequency bands are: P1, P2, P3, P4 and P5; then any two sub-frequency bands can be any group of P1 and P2, P1 and P3, P1 and P4, P1 and P5, P2 and P3, P2 and P4, P2 and P5, P3 and P4, P3 and P5, or P4 and P5.

[0109] In one embodiment, the threshold value is a maximum value used to indicate whether the base station needs to perform beamforming adjustment.

[0110] In the disclosed embodiments, a base station can obtain the measurement results of any two sub-bands and determine the difference in CSI-RSRP between the measurement results of the two sub-bands. Based on the difference between the difference and a threshold, the base station can determine whether beamforming adjustment is required. In this way, the disclosed embodiments can accurately determine whether beamforming adjustment is required.

[0111] The embodiment of the present disclosure provides a beam processing method, in which step S72 may include:

[0112] In response to an absolute value of the difference being greater than a threshold value, determining that beamforming adjustment is required;

[0113] or,

[0114] In response to the absolute value of the difference being less than or equal to the threshold value, it is determined that beamforming adjustment is not required.

[0115] For example, in response to the absolute value of the difference between the CSI-RSRP of any two sub-frequency bands being greater than a threshold value, it is determined that beamforming adjustment is required; or, in response to the absolute value of the difference between the CSI-RSRP of any two sub-frequency bands being less than or equal to the threshold value, it is determined that beamforming adjustment is not required.

[0116] If the absolute value of the difference between the CSI-RSRP values ​​of any two sub-frequency bands is greater than the threshold, the beam is severely split between the two sub-frequency bands, and beamforming adjustment is required. Alternatively, if the absolute value of the difference between the CSI-RSRP values ​​of any two sub-frequency bands is less than or equal to the threshold, the beam is not severely split between the two sub-frequency bands, and beamforming adjustment is not required.

[0117] In the disclosed embodiments, a base station can accurately determine whether beamforming adjustment is required based on the difference between the CSI-RSRP values ​​of each sub-band and a threshold value. This facilitates performing beamforming adjustment when necessary, thereby improving the communication connection quality between the UE and the base station, and thereby improving the communication quality between the UE and the base station. Alternatively, beamforming adjustment can be omitted when not necessary, thereby saving base station energy consumption.

[0118] A beam processing method provided by an embodiment of the present disclosure may include: in response to the absolute value of the difference being less than or equal to a threshold value, obtaining the CSI-RSRP measurement result of the frequency band in which the beam is located based on the CSI-RSRP measurement result measured in the frequency band.

[0119] Thus, in the embodiment of the present disclosure, if the absolute value of the difference between the CSI-RSRP of any two sub-frequency bands is less than or equal to the threshold value, the measurement result of the CSI-RSRP measured in the sub-frequency band where the beam is located can also be processed to obtain a CSI-RSRP measurement result of the frequency band where the beam is located; thereby facilitating the subsequent management of subsequent beams based on the CSI-RSRP by the base station.

[0120] An embodiment of the present disclosure provides a beam processing method, which may include:

[0121] Obtain the average value of CSI-RSRP in the measurement results of each sub-frequency band;

[0122] The average value is used as the CSI-RSRP measurement result of the frequency band where the beam is located.

[0123] Here, obtaining the average CSI-RSRP value in the measurement results of each frequency band measurement includes: in response to the absolute value of the difference being less than or equal to the threshold value, obtaining the average CSI-RSRP value in the measurement results of each sub-frequency band measurement.

[0124] In the disclosed embodiments, the base station can obtain the average CSI value from the measurement results for each sub-frequency band in which the beam is located, and use this average value as the CSI-RSRP measurement result for the frequency band in which the beam is located. Thus, in the disclosed embodiments, when the UE does not meet the CSI-RSRP reporting conditions for each sub-frequency band, the base station can determine the CSI-RSRP measurement result for the frequency band in which the beam is located based on the CSI-RSRP measurement results for each sub-frequency band, thereby facilitating the base station's subsequent management of the beam.

[0125] In other embodiments, the CSI-RSRP measurement result of the frequency band where the beam is located may not be obtained based on the average value of the CSI-RSRP in the measurement results of each sub-frequency band measurement; for example, the CSI-RSRP within a predetermined power value range of the above average value may be used as the CSI-RSRP measurement result of the frequency band where the beam is located, or any CSI-RSRP in the measurement results based on each sub-frequency band measurement may be used as the CSI-RSRP measurement result of the frequency band where the beam is located, or the maximum CSI-RSRP in the measurement results based on each sub-frequency band measurement may be used as the CSI-RSRP measurement result of the frequency band where the beam is located, and so on.

[0126] It should be noted that those skilled in the art will understand that the method provided in the embodiments of the present disclosure may be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0127] like Figure 8As shown, an embodiment of the present disclosure provides a beam processing method, applied to a UE, including:

[0128] Step S81: receiving a CSI-RSRP measurement result based on the frequency band where the beam is located; wherein the measurement result is reported based on the measurement of the frequency band where the beam is located after the UE does not meet the CSI-RSRP segment reporting condition.

[0129] The measurement result here is measured and reported based on the frequency band where the beam is located after the UE determines that the UE does not meet the CSI-RSRP segment reporting conditions.

[0130] In some embodiments, failure to meet the CSI-RSRP segment reporting condition may include: the UE does not have the CSI-RSRP segment reporting capability, and / or the bandwidth of the frequency band where the beam is located is less than or equal to the predetermined bandwidth.

[0131] In other embodiments, failure to meet the segmented CSI-RSRP reporting conditions may include: the frequency band bandwidth of the beam not requiring segmented reporting. For example, if the frequency band bandwidth of the beam is less than or equal to a predetermined bandwidth, it can be considered that the frequency band bandwidth of the beam does not require segmented reporting. Of course, in other embodiments, omitting segmented reporting of the frequency band bandwidth of the beam can be achieved by any other feasible method, which is not a limitation here.

[0132] In the disclosed embodiments, if the UE does not meet the segmented CSI-RSRP reporting conditions and cannot report CSI-RSRP measurement results by frequency band, the UE can treat the frequency band in which the beam resides as a single frequency band for CSI-RSRP measurement and report the measurement results. In this way, the base station can receive the UE's CSI-RSRP measurement results based on the frequency band in which the beam resides. In this case, the base station receives a single CSI-RSRP measurement result for the frequency band in which the beam resides.

[0133] Thus, in the embodiment of the present disclosure, if the UE does not meet the CSI-RSRP segment reporting conditions, the base station can also determine the management of the beam based on the measurement result of a total CSI-RSRP received from the UE in the frequency band where the beam is located.

[0134] An embodiment of the present disclosure provides a beam processing method, which may include:

[0135] From the CSI-RSRP measurement results of the frequency band where at least one beam is located, the beam corresponding to the maximum CSI-RSRP value is selected as the beam for communicating with the UE.

[0136] For example, if the base station uses eight beams to cover its serving cell, namely beams 1 to 8, the base station receives the CSI-RSRP measurement results of the frequency bands in which the eight beams are located. From the eight measurement results, the base station selects the beam corresponding to the maximum CSI-RSRP value. For example, if the beam corresponding to the maximum CSI-RSRP value is beam 6, the base station may select beam 6 as the beam for communicating with the UE.

[0137] The CSI-RSRP measurement result of the frequency band in which the beam is located can be obtained from the UE, or can be obtained by the base station itself based on the CSI-RSRP measurement results of multiple sub-frequency bands in which the beam is located. The method by which the base station obtains the CSI-RSRP measurement results of the multiple sub-frequency bands in which the beam is located can be any feasible method. For example, in the above-mentioned step embodiment, the CSI-RSRP of each sub-frequency band in which the beam is located is averaged, and the average value is used as the measurement result of the frequency band in which the beam is located.

[0138] In the disclosed embodiments, when a UE does not meet the segmented CSI-RSRP reporting conditions, the base station can obtain a total CSI-RSRP measurement result for the frequency band in which the beam resides. Based on the measurement results for the frequency bands in which multiple beams reside, the base station selects the beam corresponding to the maximum CSI-RSRP value, that is, the beam with the best received signal, as the beam for communication with the UE. In this way, the disclosed embodiments can also improve the quality of the communication connection between the UE and the base station, thereby improving the communication quality between the UE and the base station.

[0139] It should be noted that those skilled in the art will understand that the method provided in the embodiments of the present disclosure may be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0140] The following provides specific examples in combination with any of the above embodiments:

[0141] like Figure 9 As shown, an embodiment of the present disclosure provides a beam processing method, which is applied to a communication device, where the communication device includes a UE and a base station, including:

[0142] Step S91: The UE determines whether the segmented reporting conditions of CSI-RSRP are met; if so, execute step S92; if not, execute step S93:

[0143] In one embodiment, the UE determines whether the UE has the capability of segmented reporting of CSI-RSRP and whether the beam needs to be reported in segment; if the UE determines that the UE has the capability of segmented reporting of CSI-RSRP and the beam needs to be reported in segment, step S92 is executed; if the UE determines that the UE does not have the capability of segmented reporting of CSI-RSRP and / or does not need segmented reporting of the beam, step S93 is executed.

[0144] In one embodiment, the beam needs to be reported in segments, including: the bandwidth of the frequency band where the beam is located is greater than the predetermined bandwidth; the beam does not need to be reported in segments, including: the bandwidth of the frequency band where the beam is located is less than or equal to the predetermined bandwidth.

[0145] Step S92: The UE performs CSI-RSRP measurement based on the sub-frequency band where the beam is located, and sends the measurement result of the CSI-RSRP measured in the sub-frequency band where the beam is located to the base station;

[0146] In one embodiment, the UE divides the frequency band where the beam is located into at least one sub-frequency band; the UE performs CSI-RSRP measurement based on the sub-frequency band, and reports the measurement result of the CSI-RSRP measured in the sub-frequency band to the base station.

[0147] Step S93: The UE performs CSI-RSRP measurement based on the frequency band where the beam is located, and sends the measurement result of the CSI-RSRP measured in the frequency band where the beam is located to the base station;

[0148] Step S94: The base station determines whether the absolute value of the difference between the CSI-RSRP values ​​in the measurement results of any two sub-frequency bands is greater than a threshold value; if so, execute step S95; if not, execute step S96;

[0149] Step S95: The base station determines that beamforming adjustment is required;

[0150] Step S96: The base station determines the CSI-RSRP measurement result of the frequency band where the beam is located based on the CSI-RSRP measurement result of the sub-frequency band where the beam is located;

[0151] In one embodiment, the base station obtains an average value of CSI-RSRP measured in the sub-frequency band where the beam is located, and uses the average value as the CSI-RSRP measurement result of the frequency band where the beam is located. Here, the sub-frequency band where the beam is located is a part of the frequency band where the beam is located.

[0152] Step S97: The base station determines whether the beam is used as a beam for communicating with the UE based on the CSI-RSRP measurement result of the frequency band where the beam is located.

[0153] In one embodiment, the base station obtains CSI-RSRP measurement results of the frequency bands where multiple beams are located, and selects the beam corresponding to the maximum CSI-RSRP value from the CSI-RSRP measurement results of the frequency bands where the multiple beams are located as the beam for communicating with the UE.

[0154] Exemplarily, the UE is in a Radio Resource Control (RRC) connection state and needs to periodically report CSI-RSRP to adjust the beam direction of the base station. If the UE operates in a high frequency band, such as a frequency band above 52 GHZ, the UE continuous transmission bandwidth can be configured to be greater than or equal to 2 GHZ. If the UE has the ability to report CSI-RSRP in segments and determines that the UE meets the CSI-RSRP segment reporting conditions, the UE can perform segmented reporting based on the frequency band where the beam is located. The UE is configured to have a bandwidth of 2 GHZ for the frequency band where the beam is located and uses a 960 kHz subcarrier spacing (SCS). The UE divides the total bandwidth of 2 GHZ into 5 consecutive 400 MHZ sub-bands; the UE performs CSI-RSRP measurements on each 400 MHZ sub-band and reports the measurement results to the base station. The base station receives the measurement results of CSI-RSRP measured on the five 400 MHz sub-bands, and the CSI-RSRP power values ​​in the measurement results of the five sub-bands are: P1, P2, P3, P4 and P5. The base station obtains a difference based on the CSI-RSRP of any two sub-bands. The difference values ​​obtained by subtracting the CSI-RSRP of the arbitrary two sub-bands are 10 groups in total, namely: (P1-P2), (P1-P3), (P1-P4), (P1-P5), (P2-P3), (P2-P4), (P2-P5), (P3-P4), (P3-P5) and (P4-P5). In response to determining that the absolute value of any one of the 10 groups of differences is greater than a threshold value, the base station determines that beamforming adjustment is required. In one embodiment, the threshold value is 10 mW.

[0155] For example, the UE is in an RRC connected state and needs to periodically report CSI-RSRP to adjust the base station beam direction. If the UE operates in a low frequency band, such as a frequency band below 52 GHZ, the UE continuous transmission bandwidth can be configured to 400 MHZ. If the UE does not have the ability to report CSI-RSRP segmented, and it is determined that the UE does not meet the CSI-RSRP segmented reporting conditions, the UE can measure and report based on the frequency band where the beam is located. The UE only reports one CSI-RSRP in the entire 400 MHZ bandwidth, and the CSI-RSRP is used as the measurement result of the 400 MHZ where the beam is located. The base station receives the measurement results of different beams, and selects the beam corresponding to the CSI-RSRP with the largest CSI-RSRP from multiple measurement results as the beam for communicating with the UE.

[0156] In an embodiment of the present disclosure, when the UE meets the CSI-RSRP segment reporting conditions, the measurement results of CSI-RSRP can be measured and reported based on the sub-frequency band where the beam is located, so that the base station can determine whether beamforming adjustment is required based on the measurement results of CSI-RSRP measured in the sub-frequency band; if the CSI-RSRP of any two sub-frequency bands in the measurement results of the sub-frequency band CSI-RSPR is greater than the threshold value, it is determined that beamforming adjustment is required. In this way, the embodiment of the present disclosure can reduce the occurrence of the situation where the beam cannot be concentrated due to beam splitting, can enhance the directional gain of the entire frequency band where the beam is located, can improve the quality of the communication connection between the UE and the base station, and thus improve the communication quality between the UE and the base station.

[0157] Alternatively, when the UE does not meet the CSI-RSRP segment reporting conditions, CSI-RSRP measurement can be performed based on the entire frequency band where the beam is located and the measurement results can be reported, so that the base station can know the CSI-RSRP measurement results of the frequency band where the beam is located; and the base station can select a beam with the best CSI-RSRP measurement result as the beam for communication with the UE based on the CSI-RSRP measurement results of the frequency bands where multiple beams are located. In this way, the embodiment of the present disclosure can improve the quality of the communication connection between the UE and the base station when the UE does not meet the CSI-RSRP segment reporting conditions and cannot report the CSI-RSRP measurement results by frequency band, thereby improving the communication quality between the UE and the base station.
