Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a beam adaptive adjustment method, apparatus, base station equipment, and storage medium. Background Art

[0002] With the explosive growth of data services in modern mobile communications, traditional communication frequency bands are no longer able to meet the gigabit data rates and millisecond latency requirements of fifth-generation mobile communications (5G). Millimeter-wave frequency bands offer abundant spectrum resources, making millimeter-wave communications a core technology for 5G. Another core technology for 5G communications is Large Scale Multiple Input Multiple Output (LS-MIMO). LS-MIMO utilizes multi-antenna arrays with 256 or even 512 antenna elements, using high-gain beams to segment the space, thereby improving spectrum utilization and reducing interference.

[0003] In current research and application, multi-antenna arrays typically use beamforming technology to focus wireless signal energy, forming a narrow, directional beam. Generally, a narrower beam increases signal gain and allows for longer coverage. Beam tracking technology allows user devices to be positioned within the narrow beam's direction, providing high-quality communication services.

[0004] However, there are often multiple user devices within the coverage area of ​​a single base station. If the user device deviates from the direction of the narrow beam, the user device will not receive high-quality wireless signals, that is, there is a problem of weak coverage or even zero coverage outside the beam direction. Therefore, how to provide high-quality signal coverage for user devices outside the beam direction has become an urgent problem to be solved. Summary of the Invention

Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0067] In order to facilitate a clearer understanding of the various embodiments of the present application, some relevant technical knowledge is first introduced as follows.

[0068] The technical solution provided in the embodiment of the present application can be applicable to a variety of systems, especially 5G systems. For example, the applicable system can be a global system of mobile communication (GSM) system, a code division multiple access (CDMA) system, a wideband code division multiple access (WCDMA) general packet radio service (GPRS) system, a long term evolution (LTE) system, a LTE frequency division duplex (FDD) system, a LTE time division duplex (TDD) system, an advanced long term evolution (LTE-A) system, a universal mobile telecommunication system (UMTS), a world-wide interoperability for microwave access (WiMAX) system, a 5G new air interface (NR) system, etc. These various systems include terminal equipment and network equipment. The system may also include a core network part, such as an evolved packet system (EPS), a 5G system (5GS), etc.

[0069] The terminal device involved in the embodiments of the present application may be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connection function, or other processing devices connected to a wireless modem. In different systems, the name of the terminal device may also be different. For example, in a 5G system, the terminal device may be called a user equipment (UE). A wireless terminal device can communicate with one or more core networks (CN) via a radio access network (RAN). The wireless terminal device can be a mobile terminal device, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal device. For example, it can be a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device that exchanges language and / or data with a radio access network. For example, personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), and other devices. The wireless terminal device may also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote terminal device, an access terminal device, a user terminal device, a user agent, or a user device, but is not limited in the embodiments of the present application.

[0070] The network device involved in the embodiments of the present application may be a base station, which may include multiple cells providing services to terminals. Depending on the specific application scenario, the base station may also be called an access point, or may be a device in an access network that communicates with a wireless terminal device through one or more sectors on an air interface, or may be named otherwise. The network device may be used to interchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal device and the rest of the access network, wherein the rest of the access network may include an Internet Protocol (IP) communication network. The network device may also coordinate attribute management of the air interface. For example, the network device involved in the embodiments of the present application may be a network device (Base Transceiver Station, BTS) in the Global System for Mobile communications (GSM) or Code Division Multiple Access (CDMA), or a network device (NodeB) in Wide-band Code Division Multiple Access (WCDMA), or an evolutionary network device (eNB or e-NodeB) in the Long Term Evolution (LTE) system, a 5G base station (gNB) in the 5G network architecture (next generation system), or a home evolved Node B (HeNB), a relay node, a home base station (femto), a pico base station (pico), etc., and is not limited in the embodiments of the present application. In some network structures, the network device may include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit may also be geographically separated.

[0071] Network devices and terminal devices can each use one or more antennas for Multiple Input Multiple Output (MIMO) transmission. MIMO transmission can be either Single User MIMO (SU-MIMO) or Multi User MIMO (MU-MIMO). Depending on the configuration and number of antenna combinations, MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO, or Massive-MIMO. It can also use diversity transmission, precoding, or beamforming.

[0072] In the current 5G era, millimeter waves utilize hybrid beams, and these large-scale antenna arrays also enable the emergence of narrow beams with wide coverage. Their ultra-low beamwidth also enables them to distinguish even closer targets, providing better directionality for point-to-point communications. Currently, millimeter waves are widely discussed for narrow-beam point-to-point communications and narrow-beam tracking in V2X (Vehicle to Everything) and high-speed rail. Examples include V2X beam directional scanning communications and beam tracking. In high-speed rail scenarios, a method for narrow-beam point-to-point communication and narrow-beam beam tracking is as follows: given a target data rate as a reference rate, the difference between the average rate within the coverage area of ​​each transmit beam and the given target data rate is minimized, thereby stabilizing the data transmission rate near the target rate. Base stations at different locations use transmit beams of different widths to provide services to user devices carried by the high-speed rail. When the distance between the base station and the high-speed rail is long, a wide beam with low beamforming gain is used to provide wider coverage. When the distance between the base station and the high-speed rail is close, a narrow beam with high beamforming gain is used to compensate for the path loss caused by the long distance. This ensures that the high-speed rail is within the signal coverage area during its travel, ensuring the stability of wireless communication data transmission on the high-speed rail.

[0073] However, current technologies focus on narrow-beam point-to-point communication and narrow-beam beam tracking, ignoring the problems of zero coverage and weak coverage between narrow beams. There is a lack of beam width adjustment solutions for fixed directions, and the capacity advantages of millimeter waves and the advantages of analog beam width that are easy to change and control are not fully utilized.

[0074] The embodiments of the present application use beamforming technology for multi-antenna arrays, so that narrow beams with extremely low width can cover longer distances. However, as the beams become rapidly narrower and their directionality increases, there are application scenarios with zero coverage and weak coverage between the beams of the millimeter wave system.

[0075] Figure 1This is one of the flow charts of the beam adaptive adjustment method provided in the embodiment of the present application, which is applied to a base station, such as Figure 1 As shown, the method includes the following steps:

[0076] Step 110: Receive a first beam measurement report, where the first beam measurement report includes one or more first parameter values, where the first parameter values ​​are used to indicate a signal quality of a millimeter wave beam measured by the user equipment;

[0077] Specifically, the beam management process involves a beam measurement step, in which the UE (User Equipment) measures the quality and characteristics of the received reference signal to identify the optimal beam. Following the beam measurement step, there is a beam reporting step, in which the UE reports the beam measurement results. In one embodiment, the millimeter wave system configures multiple initial narrow beams. Users detect and report millimeter wave beam information and report the signal status of the measured beam to the base station.

[0078] Step 120: Perform millimeter wave beam adaptive adjustment based on the first beam measurement report, where the millimeter wave beam adaptive adjustment includes adjusting the width of the millimeter wave beam.

[0079] Specifically, in order to ensure that sufficient signal gain is ultimately obtained, the beam generated by the large-scale antenna array will usually become very narrow and have strong directivity. Outside the direction of the beam, the user equipment cannot obtain effective signal coverage. In order to make the user within the direction of the beam, beam alignment is required, and the base station needs to use multiple narrow beams to ensure that users in any direction within the cell can be effectively covered. However, after beam alignment, user equipment in a certain direction may not all fall completely within the direction of the beam. There may be one or more user equipment that is close to the direction of a beam and can obtain coverage from the beam, but is slightly offset and has poor signal quality. At the same time, it is far away from other beams and cannot obtain coverage from other beams. In this case, the beam adaptive adjustment method provided in the embodiment of the present application can adjust the width of the beam so that the above-mentioned one or more user equipment fall within the direction of the beam, thereby improving the signal quality.

[0080] The beam adaptive adjustment method provided in the embodiment of the present application adjusts the millimeter wave beam width according to the beam measurement report reported by the terminal, thereby achieving adaptive adjustment of wide and narrow beams and improving the signal coverage of large-scale antenna arrays.

[0081] Figure 2 This is one of the schematic diagrams of beam coverage of the beam adaptive adjustment method provided in the embodiment of the present application, such as Figure 2As shown, the scenario of this embodiment includes an independently networked base station and multiple user equipments, and the independently networked base station uses a large-scale antenna array to transmit millimeter waves.

[0082] Optionally, performing millimeter wave beam adaptive adjustment based on the first beam measurement report includes:

[0083] When the first beam measurement report includes first parameter values ​​of two or more millimeter wave beams, and the first parameter values ​​are all less than a first threshold, selecting the millimeter wave beam corresponding to the largest first parameter value among the first parameter values ​​as the first millimeter wave beam;

[0084] Specifically, in the SA (Standalone, independent networking) scenario, the user equipment detects the signal quality of the millimeter wave beam in the beam measurement step, and accordingly reports the signal quality of the millimeter wave beam in the beam reporting step.

[0085] The width of the first millimeter-wave beam is adjusted from a first width to a second width; wherein the second width is greater than the first width.

[0086] Specifically, the base station needs to cover multiple user devices. To ensure that the user devices receive sufficient signal quality, the base station needs to use multiple narrow beams to aim at the user devices. However, some user devices may be close to the base station but slightly deviate from the direction of the beam. Therefore, the measured signal quality will be less than the predetermined threshold, and the user experience will be poor. Figure 2 As shown, one or more user devices have deviated from the direction of the beam. In this case, the user device can receive two or more millimeter-wave beams, but does not completely fall within the direction of any millimeter-wave beam. Therefore, the signal quality of the measured millimeter-wave beams is less than a predetermined threshold. After the base station receives the beam measurement report reported by the user device, it selects the millimeter-wave beam with the best signal quality among the millimeter-wave beams reported by the user device as the first millimeter-wave beam, adjusts the first millimeter-wave beam from a narrow beam to a wide beam, so that the user device falls within the direction of the first millimeter-wave beam, and improves the signal quality measured by the user device.

[0087] The adaptive beam adjustment method provided in this embodiment of the application compensates for the shortcomings of narrow-beam transmission used by large-scale antenna arrays by adjusting the beam width while maintaining a fixed beam direction based on beam measurement reports submitted by user devices. This allows UEs that have an advantage in distance but not in direction to be covered or better covered. By increasing signal coverage by adjusting the beam width in a fixed direction, the performance of the entire millimeter wave system can be optimized.

[0088] Figure 3This is a second schematic diagram of beam coverage of the beam adaptive adjustment method provided in an embodiment of the present application, such as Figure 3 As shown, the scenario of this embodiment includes a base station of heterogeneous frequency networking and multiple user equipments, and the base station of heterogeneous frequency networking transmits millimeter waves and non-millimeter waves.

[0089] Optionally, the first beam measurement report further includes:

[0090] A second parameter value used to indicate the signal quality of the non-millimeter wave beam measured by the user equipment.

[0091] Specifically, in heterogeneous frequency networking scenarios such as NSA (Non-Standalone) or NRDC (New Radio Dual Connectivity), the user equipment detects the signal quality of the millimeter wave beam and the signal quality of the non-millimeter wave beam in the beam measurement step, and accordingly reports the signal quality of the millimeter wave beam and the signal quality of the non-millimeter wave beam in the beam reporting step.

[0092] The 3GPP standard for 5G primarily includes two frequency bands: the low- to medium-frequency FR1, also known as the Sub-6 GHz band, also known as the centimeter wave band; and the high-frequency FR2, often referred to as millimeter wave because of its millimeter wavelength. In one embodiment, when a user device is dual-connected to Sub-6 and millimeter wave, it detects the signal quality of both the millimeter wave beam and the centimeter wave beam during the beam measurement step and, accordingly, reports the signal quality of both the millimeter wave beam and the centimeter wave beam during the beam reporting step.

[0093] Optionally, performing millimeter wave beam adaptive adjustment based on the first beam measurement report includes:

[0094] When the first parameter value is less than a first threshold value and the second parameter value is greater than a second threshold value, selecting the millimeter wave beam corresponding to the largest first parameter value among the first parameter values ​​as the first millimeter wave beam;

[0095] The width of the first millimeter-wave beam is adjusted from a first width to a second width; wherein the second width is greater than the first width.

[0096] Specifically, the shorter the wavelength, the worse the penetration ability, so centimeter waves have stronger penetration ability than millimeter waves, but millimeter waves have larger bandwidth and faster transmission speeds. Therefore, in the scenario of heterogeneous frequency networking, the signal coverage of centimeter waves emitted by the base station is higher, and the signal quality of centimeter waves received by the UE is more stable, but the signal coverage of millimeter waves is lower, and the UE may not be within the coverage of the millimeter wave signal. The UE will expect to be within the coverage range of the millimeter wave and experience higher data transmission speeds. Figure 3 As shown, the user equipment may be completely within the coverage of a non-millimeter wave beam, but deviate from the direction of the millimeter wave beam. Therefore, the measured signal quality of the non-millimeter wave beam is greater than a predetermined threshold, while the measured signal quality of the millimeter wave beam is less than a predetermined threshold. After receiving the beam measurement report reported by the user equipment, the base station selects the millimeter wave beam with the best signal quality as the first millimeter wave beam reported by the user equipment based on the beam measurement report, and adjusts the first millimeter wave beam from a narrow beam to a wide beam, so that the user equipment falls within the direction of the first millimeter wave beam, thereby improving the millimeter wave signal quality measured by the user equipment.

[0097] The beam adaptive adjustment method provided in the embodiment of the present application adjusts the millimeter wave beam width in the scenario of heterofrequency networking, so that the user equipment covered by the low-frequency beam can be covered by the high-frequency millimeter wave beam in the case of poor experience, such as when the user equipment is at the edge of the low-frequency beam coverage area or there are too many user equipment in the low-frequency beam coverage area, thereby improving the millimeter wave beam coverage rate and enhancing the user experience quality.

[0098] Figure 4 This is a third schematic diagram of beam coverage of the beam adaptive adjustment method provided in an embodiment of the present application, such as Figure 4 As shown, the scenario of this embodiment includes a base station of heterogeneous frequency networking and multiple user equipments, and the base station of heterogeneous frequency networking transmits millimeter waves and non-millimeter waves.

[0099] Optionally, performing millimeter wave beam adaptive adjustment based on the first beam measurement report includes:

[0100] When the first parameter value is greater than or equal to a first threshold and the second parameter value is less than or equal to a second threshold, adapt the second millimeter wave beam and fix the direction and width of the second millimeter wave beam; wherein the second millimeter wave beam is used to cover the user equipment.

[0101] Specifically, in the beam management process, there is a beam scanning step, which means that within a specific period or time period, a beam is sent or received in a pre-set manner to cover a specific spatial area. Some UEs may deviate from the direction of the non-millimeter wave beam, but can fall into the coverage of the millimeter wave beam. Figure 4 As shown, there is a UE at the edge of the coverage range of the non-millimeter wave beam. The signal quality of the millimeter wave beam measured by the UE is greater than the predetermined threshold, and the signal quality of the non-millimeter wave beam is less than the predetermined threshold. After receiving the beam measurement report reported by the user equipment, the base station can adapt a millimeter wave beam, that is, adapt a narrow beam to transmit a signal directionally, so that the UE falls into the coverage range of the millimeter wave beam, and fix the direction and width of the millimeter wave beam, thereby ensuring the stability of the UE's signal quality.

[0102] Specifically, in another scenario, some UEs may fall within the coverage of the millimeter wave beam, and the base station system learns through other means that it needs to adapt a millimeter wave beam for the UE to ensure that the signal quality of the UE is greater than a predetermined threshold. For example, the base station knows that there is a special user and needs to provide long-term millimeter wave beam coverage for the special user. Regardless of whether the non-millimeter wave beam signal quality measured by the user is greater than the predetermined threshold, the base station can adapt a narrow beam in the direction of the special user. After receiving the beam measurement report reported by the user equipment, the base station can adapt a millimeter wave beam, that is, adapt a narrow beam to transmit a directional signal, so that the UE falls within the coverage of the millimeter wave beam, and fix the direction and width of the millimeter wave beam, thereby ensuring the stability of the UE's signal quality.

[0103] The beam adaptive adjustment method provided in the embodiment of the present application can ensure that the user equipment can be covered by the millimeter wave narrow beam by adapting a narrow beam directional transmission signal in the scenario of heterogeneous frequency networking, regardless of the quality of the low-frequency signal, thereby providing millimeter wave dedicated coverage and millimeter wave optimal coverage in scenarios of heterogeneous frequency networking such as millimeter wave and sub-6.

[0104] Figure 5 This is a second flow chart of the beam adaptive adjustment method provided in an embodiment of the present application, as shown in FIG. Figure 5 As shown, the beam adaptive adjustment method provided in the embodiment of the present application also includes the following steps:

[0105] Step 130: Receive a second beam measurement report, where the second beam measurement report includes a third parameter value indicating signal quality measured by the user equipment;

[0106] Specifically, in the beam management process, after performing millimeter wave beam adaptive adjustment, the UE performs beam measurement again and reports the beam measurement result again.

[0107] Step 140: When the third parameter value indicates that the signal quality of the millimeter wave beam is less than a first threshold, restore the width of the millimeter wave beam to an initial width.

[0108] Specifically, it may happen that the beam adaptive adjustment method provided in the embodiment of the present application does not make the signal quality of the millimeter wave beam greater than or equal to the first threshold, that is, after the millimeter wave beam adaptive adjustment is performed, the UE is not completely within the coverage of the millimeter wave beam. In this case, a beam recovery step is required. In the beam adaptive adjustment method provided in the embodiment of the present application, the width of the millimeter wave beam needs to be restored to the initial width, and then other steps such as beam scanning can be continued to provide signal coverage for the user. For example, a hierarchical scanning strategy can be adopted, that is, scanning from wide to narrow. The first stage is a coarse scan, in which the base station uses a small number of wide beams to cover the entire cell and scans the directions aligned with each wide beam in turn. The second stage is a fine scan, in which the base station uses multiple narrow beams to scan one by one the directions covered by the wide beam in the first stage. In summary, after the width of the millimeter wave beam is restored to the initial width, it is basically the same as the case where the beam adaptive adjustment method provided in the embodiment of the present application is not adopted. Therefore, various existing or future invented beam management methods can be used to provide signal coverage for users.

[0109] Step 150: When the third parameter value indicates that the signal quality of the millimeter wave beam is greater than or equal to a first threshold, fix the width and direction of the millimeter wave beam.

[0110] Specifically, there is a situation where the beam adaptive adjustment method provided in an embodiment of the present application makes the signal quality of the millimeter wave beam greater than or equal to a first threshold, that is, after the millimeter wave beam adaptive adjustment is performed, the UE is within the coverage of the millimeter wave beam. In this case, the width and direction of the millimeter wave beam are fixed so that stable signal coverage can be provided to the user.

[0111] Optionally, the first parameter value, the second parameter value, and the third parameter value include at least one of the following:

[0112] Reference signal received power RSRP, reference signal received quality RSRQ, and signal to interference plus noise ratio SINR.

[0113] Specifically, common measurement parameters related to signal status, such as RSRP (Reference Signal Receiving Power), RSRQ (Reference Signal Receiving Quality), and SINR (Signal to Interference plus Noise Ratio), can all be used as parameter values ​​for indicating the signal quality measured by the user equipment.

[0114] Figure 6This is a flowchart of the beam adaptive adjustment method provided in the embodiment of the present application. Figure 6 As shown, the beam adaptive adjustment method provided in the embodiment of the present application includes the following steps:

[0115] Step 600: configuring initial millimeter-wave narrow beams in multiple directions;

[0116] Specifically, the millimeter wave system is configured with multiple initial narrow beams, and the networking mode is detected and reported after the user accesses.

[0117] Step 601: Perform beam scanning;

[0118] Specifically, after beam scanning, the networking scenario is determined. If it is a standalone (SA) scenario, the user only detects and reports the millimeter wave beam information and reports the signal status of the measured beam to the base station, and then proceeds to step 606.

[0119] If it is an NSA / NRDC networking scenario, the user needs to detect and report the signal quality of the non-millimeter wave system and the signal quality of the millimeter wave system, and then proceed to step 602.

[0120] Specifically, in the heterogeneous frequency networking scenario:

[0121] Step 602: Receive millimeter wave and non-millimeter wave beam measurement reports;

[0122] Specifically, the base station receives the signal quality of the non-millimeter wave system and the signal quality of the millimeter wave system reported by the user.

[0123] When the user feedback information satisfies that the non-millimeter wave system signal quality is greater than the set value and the millimeter wave system signal quality is lower than the set value (for example, using RSRP as the reference signal), the process proceeds to step 603;

[0124] If in the heterofrequency networking NSA / NRDC networking scenario, the base station receives a user report that the signal quality of the non-millimeter wave system is lower than the set value and the signal quality of the millimeter wave system beam is greater than the set value, or if it is known before the system is deployed that a narrow beam needs to be fixed in a certain direction to cover special users, then proceed to step 607.

[0125] Step 603: Adjust the millimeter wave beam corresponding to the maximum parameter value to a wide beam;

[0126] Specifically, the base station selects the beam with the best signal quality reported by the user and adapts it to the wide beam.

[0127] Step 604: Receive a millimeter wave beam measurement report;

[0128] Specifically, after adapting to the wide beam, the user reports the millimeter wave beam signal quality again;

[0129] When the base station receives a beam signal quality report from the user that is greater than the set threshold, the existing beam scene is maintained and the process proceeds to step 605 ; until the beam signal quality does not meet the reporting threshold, the initial state of the beam is restored and the process proceeds to step 608 .

[0130] Step 605: Fixing the millimeter wave beam width and / or beam direction;

[0131] Specifically, when the beam information reported by the user detected and received by the base station is greater than a set threshold, the beam width and beam direction are fixed.

[0132] Step 608: Restoring the millimeter wave beam to an initial state;

[0133] Specifically, after adapting to the wide beam, if the user reports again that the millimeter wave beam signal quality does not meet the reporting threshold, the initial state of the beam is restored.

[0134] Step 607: Adapting the directional transmission of the millimeter wave narrow beam;

[0135] Specifically, in the NSA / NRDC networking scenario, when the base station receives a user report that the signal quality of the non-millimeter wave system is lower than the set value and the signal quality of the millimeter wave system beam is greater than the set value, it adapts a narrow beam to directional transmit the signal; for example, in some embodiments, in the case of weak sub6 coverage, a fixed millimeter wave beam can be used to improve the user experience. In other embodiments, when it is known before the system is deployed that a narrow beam needs to be fixed in a specific direction to cover a special user, a fixed narrow beam can be set in that direction for long-term coverage.

[0136] Subsequently, the base station determines whether the beam information detected and reported by the user is greater than a preset threshold. If it is greater than the preset threshold, step 605 is executed; otherwise, step 608 is executed.

[0137] Accordingly, in a standalone network scenario:

[0138] Step 606: Receive a millimeter wave beam measurement report;

[0139] Specifically, if it is an independent networking SA scenario, the user only detects and reports the beam information of the millimeter wave, and reports the signal status of the measured beam to the base station. When the base station receives no less than 2 beam information reported by the user, and both are lower than the set threshold (for example, using RSRP as the reference signal), it proceeds to step 603 and executes subsequent steps accordingly.

[0140] If in the independent networking SA scenario, when the beam information reported by the user detected and received by the base station is greater than the set threshold, the process proceeds to step 608.

[0141] The beam adaptive adjustment method provided in the embodiments of the present application can be applied to all scenarios requiring coordinated coverage of wide and narrow beams, including those involving inter-band networking such as millimeter wave and sub-6. The beam adaptive adjustment method provided in the embodiments of the present application can address the shortcomings of using large-scale antennas for narrow beam long-distance transmission. By increasing capacity or coverage by adjusting the width of the beam in a fixed direction, the system's signal coverage and information transmission quality can be improved.
