Description

Technical Field

[0001] The present application relates to the field of communication technology. Specifically, the present application relates to a method, apparatus, device and computer-readable storage medium for determining an uplink receive beam. Background Art

[0002] Currently, mobile communication systems mainly use microwave frequency bands below 6 GHz, among which frequency bands below 3 GHz are more commonly used. The receiving beams corresponding to uplink time slots are all wide beams. For example, a sector can use a 120-degree wide beam to receive uplink signals.

[0003] Fifth-generation mobile communications (5G) support both low-frequency bands and high-frequency bands (millimeter waves). Currently, mobile communication systems primarily utilize low-frequency bands. However, spectrum resources in these bands are becoming increasingly scarce, significantly limiting support for high-data-rate services. Millimeter-wave bands, on the other hand, offer ample available spectrum resources, which can significantly alleviate the increasing pressure on spectrum resources and meet the demand for high-bandwidth, high-speed services.

[0004] When using the millimeter wave frequency band, the path loss of the millimeter wave signal is large. Therefore, to ensure the coverage of the millimeter wave signal, the millimeter wave base station needs to use a directional narrow beam to send the downlink signal, and also needs to use a directional narrow beam to receive the uplink signal. This means that on the millimeter wave base station side, there are multiple transmit beams for the downlink and multiple receive beams for the uplink. However, the existing low-frequency uplink receive wide beam is not suitable for millimeter wave systems. Therefore, how the millimeter wave base station selects the uplink receive beam is an issue that needs to be considered. Summary of the Invention

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.

Depending on the form and number of antenna combinations, MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO, or massive-MIMO. It can also be diversity transmission, precoded transmission, or beamforming transmission.

[0036] Fifth-generation mobile communications (5G) support both low-frequency bands and high-frequency bands (millimeter waves). Currently, mobile communication systems primarily utilize low-frequency bands. However, spectrum resources in these bands are becoming increasingly scarce, significantly limiting support for high-data-rate services. Millimeter-wave bands, on the other hand, offer ample available spectrum resources, which can significantly alleviate the increasing pressure on spectrum resources and meet the demand for high-bandwidth, high-speed services.

[0037] When using the millimeter wave frequency band, the path loss of the millimeter wave signal is large. Therefore, to ensure the coverage of the millimeter wave signal, the millimeter wave base station needs to use a directional narrow beam to send the downlink signal, and also needs to use a directional narrow beam to receive the uplink signal. This means that on the millimeter wave base station side, there are multiple transmit beams for the downlink and multiple receive beams for the uplink. However, the existing low-frequency uplink receive wide beam is not suitable for millimeter wave systems. Therefore, how the millimeter wave base station selects the uplink receive beam is an issue that needs to be considered.

[0038] In view of this, the present invention provides an adaptive uplink receive beam selection method in a millimeter wave communication system. Using the solution in this embodiment, while ensuring coverage, it is possible to minimize scheduling restrictions on users caused by narrowing the uplink receive beam, thereby improving cell throughput and spectrum efficiency in millimeter wave communication.

[0039] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0040] The embodiment of the present application provides a method for determining an uplink receive beam, such as Figure 1 As shown, the method includes:

[0041] S100: Periodically determine an uplink receive beam for a first user equipment (UE) to be scheduled, wherein determining the uplink receive beam within a period includes:

[0042] S101. Determine a first uplink receive beam coverage level of the first UE to be scheduled based on a signal quality of the first UE to be scheduled and multiple preset thresholds, and a preset first correspondence, wherein the first correspondence is a correspondence between the multiple preset thresholds and each preset uplink receive beam coverage level;

[0043] S102: Determine an uplink receive beam for the first UE to be scheduled from all beams corresponding to the first uplink receive beam coverage level based on the home beam of the first UE to be scheduled, wherein the home beam of the UE is the narrowest downlink transmit beam to which the UE belongs.

[0044] Specifically, in this embodiment, the duration of the cycle is any one of one time slot, multiple time slots, one symbol, and multiple symbols. That is, the process of determining the uplink receive beam for the first user equipment to be scheduled UE is performed once every one time slot, multiple time slots, one symbol, or multiple symbols.

[0045] The method in the above embodiment, by periodically determining the uplink receive beam for the UE to be scheduled, can minimize the scheduling user restrictions caused by the narrowing of the uplink receive beam while ensuring coverage, thereby improving the cell throughput and spectrum efficiency under millimeter waves.

[0046] In some embodiments, S102 may include:

[0047] Based on the belonging beam of the first UE to be scheduled, a first beam is selected as the uplink receiving beam of the first UE to be scheduled from all beams corresponding to the first uplink receiving beam coverage level, wherein the beam coverage area of the first beam includes the beam coverage area of the belonging beam of the first UE to be scheduled.

[0048] That is, from the beams corresponding to the determined uplink receive beam coverage levels, a beam whose beam coverage area includes the beam coverage area of the home beam of the first UE to be scheduled can be selected as the uplink receive beam of the first UE to be scheduled. That is, the beam coverage area of the uplink receive beam determined for the first UE to be scheduled includes the beam coverage area of the home beam of the first UE to be scheduled.

[0049] In the above embodiment, the first UE to be scheduled is any one of the following:

[0050] The UE with the highest scheduling priority among multiple UEs currently to be scheduled;

[0051] The UE corresponding to the highest scheduling priority among the multiple UEs is a UE with the same belonging beam.

[0052] That is to say, if there are multiple UEs to be scheduled, the UE corresponding to the highest scheduling priority can be selected as the first UE to be scheduled, or at least two UEs can be selected as the first UE to be scheduled. The conditions satisfied by the at least two UEs selected are: the UEs have the same belonging beam, and the belonging beam is the belonging beam of the UE with the highest scheduling priority among the multiple UEs to be scheduled.

[0053] For example: there are 5 UEs to be scheduled, which are recorded as: A, B, C, D, and E. Among them, the UE with the highest priority is D, and the UEs with the same belonging beam as D are A and C. Then, the first UE to be scheduled is D, or the first UE to be scheduled is A, C, and D.

[0054] Specifically, in this embodiment, S101 may include:

[0055] When the first UE to be scheduled is the UE corresponding to the highest scheduling priority among the multiple UEs currently to be scheduled, the uplink receiving beam coverage level of the UE is determined based on the signal quality of the UE and multiple preset thresholds, and the correspondence between the multiple preset thresholds and the preset uplink receiving beam coverage levels.

[0056] or,

[0057] When the first UE to be scheduled is at least two UEs selected from multiple UEs currently to be scheduled, the signal quality of the first UE to be scheduled can be the average signal quality of the at least two selected UEs or the signal quality corresponding to the UE with the worst signal quality among the signal qualities of the at least two selected UEs. The uplink receiving beam coverage level of the first UE to be scheduled is determined based on the determined signal quality and multiple preset thresholds, and the correspondence between the multiple preset thresholds and the preset uplink receiving beam coverage levels.

[0058] For example: there are 5 UEs to be scheduled (ABCDE), the UE with the highest priority is D, and the UEs with the same assigned beam as D are A and C. Then, when the first UE to be scheduled is A, C, and D, the signal quality of the first UE to be scheduled is the average signal quality of A, C, and D, or the worst signal quality among A, C, and D.

[0059] In some other embodiments, the method further comprises:

[0060] Determining, based on the uplink receive beam and a preset second correspondence, a set of narrowest downlink transmit beams corresponding to when the uplink receive beam is used for uplink signal reception, wherein the second correspondence is a correspondence between beam coverage areas of beams corresponding to respective preset uplink receive beam coverage levels and the beam coverage area of the narrowest downlink transmit beam;

[0061] The schedulable UEs are determined according to the set of the narrowest downlink transmission beams and the home beams of the multiple UEs.

[0062] Specifically, in this embodiment, determining the schedulable UE according to the set of the narrowest downlink transmission beams and the home beams of the multiple UEs includes:

[0063] A UE among the multiple UEs, whose belonging beam is a beam in the set of the narrowest downlink transmission beams, is determined as the schedulable UE.

[0064] That is, after the uplink receive beam is determined for the first UE to be scheduled, the set of the narrowest downlink transmit beams corresponding to uplink signal reception using the uplink receive beam can be determined based on the correspondence between the beam coverage areas of the beams corresponding to the preset uplink receive beam coverage levels and the beam coverage areas of the narrowest downlink transmit beams. Furthermore, more UEs can be selected from the UEs to be scheduled for scheduling, and the condition satisfied by the selected UEs is that the UE's home beam belongs to a beam in the set of the narrowest downlink transmit beams. In this way, the restrictions on scheduling users caused by the narrowing of the uplink receive beam can be effectively reduced.

[0065] In some other embodiments, the method further comprises:

[0066] Determine, based on the obtained first signal quality and the reception gain of the beam corresponding to the first uplink reception beam coverage level compared to the beam corresponding to the second uplink reception beam coverage level for uplink signal reception, the second signal quality when the beam corresponding to the first uplink reception beam coverage level is used for uplink signal reception, wherein the second uplink reception beam coverage level is any uplink reception beam coverage level among all preset uplink reception beam coverage levels;

[0067] A corresponding second modulation and coding strategy MCS level is obtained according to the second signal quality mapping, and the schedulable UE is scheduled based on the second MCS level to use the uplink receiving beam to receive uplink signals.

[0068] That is to say, since the beams corresponding to different uplink receiving beam coverage levels correspond to different uplink receiving gains, after determining the uplink receiving beam, it is also necessary to determine the signal quality when using the beam corresponding to the coverage level for uplink signal reception based on the uplink receiving gain of the beam in other coverage levels relative to the coverage level to which the uplink receiving beam belongs, and then obtain the modulation and coding strategy MCS level, and use the MCS level to schedule the selected schedulable UE to use the above-mentioned uplink receiving beam for uplink signal reception.

[0069] In some optional embodiments, the method further comprises:

[0070] Normalize the MCS level of each beam corresponding to the uplink receive beam coverage level when receiving uplink signals to the first MCS level of the beam corresponding to the preset uplink receive beam coverage level when receiving uplink signals and perform correction and maintenance;

[0071] The corresponding first signal quality is obtained according to the first MCS level mapping.

[0072] In some other embodiments, before periodically determining an uplink receive beam for the first user equipment to be scheduled UE, the method further includes:

[0073] Determine the maximum uplink receive beam coverage level number corresponding to the highest uplink receive beam coverage level according to the number of the narrowest downlink transmit beams corresponding to when the narrowest downlink transmit beam is used for signal transmission in the entire cell area;

[0074] Dividing the uplink receive beams into different coverage levels among the determined multiple uplink receive beam coverage levels according to the number of uplink receive beams required to complete uplink signal reception in the entire cell area, and obtaining a second corresponding relationship;

[0075] The second corresponding relationship is a corresponding relationship between the beam coverage area of each uplink receiving beam coverage level and the beam coverage area of the narrowest downlink transmitting beam.

[0076] Specifically, in this embodiment, the beam coverage areas of beams in different coverage levels satisfy the following relationship: the beam coverage area of a beam in a low coverage level includes the beam coverage area of a beam in a high coverage level.

[0077] In the millimeter wave communication system, the uplink direction can be completed by one uplink receiving beam alone or multiple uplink receiving beams together to complete the reception of uplink signals in the entire cell area. Figure 2-5 The technical solution of a method for determining an uplink receive beam provided in this application is described in detail.

[0078] 1. Divide the uplink receiving beams into different coverage levels according to the number of uplink receiving beams required to complete the uplink signal reception in the entire cell area.

[0079] The number of narrowest uplink receive beams is the same as the number of narrowest downlink transmit beams, and the beam coverage is reciprocal, meaning the coverage is considered equal. The number of narrowest downlink transmit beams determines the maximum number of coverage levels that can be divided. The maximum number of coverage levels can be calculated using the following formula:

[0080] The maximum coverage level number N=log2(the number of the narrowest downlink transmission beams)+1.

[0081] Then, based on the signal quality of the narrowest downlink transmit beam (such as SRP or SNR), the preset thresholds corresponding to each coverage level are determined, and the corresponding relationship between multiple preset thresholds and the preset coverage levels of each uplink receive beam is obtained. For example, you can refer to the attached Figure 2 In the example diagram, preset threshold 1>preset threshold 2>preset threshold 3>preset threshold 4>preset threshold 5>…>preset threshold N-1.

[0082] 2. According to the number of uplink receiving beams corresponding to the uplink receiving beam coverage level, the corresponding uplink receiving beam weights are pre-designed and stored (i.e., one beam direction corresponds to one weight). The beam coverage area of the beam corresponding to the low coverage level has an inclusive relationship with the beam coverage area of the beam corresponding to the high coverage level. That is, one beam coverage in the high coverage level needs to be attributed to one beam coverage in the low coverage level. For example, you can refer to the attached Figures 3a-3d In the example diagram, coverage level 1 is a low coverage level, coverage level 2 is a second-highest coverage level, and coverage level 3 is a high coverage level.

[0083] 3. Based on the comparison of the signal quality (such as signal-to-noise ratio, receiving power, etc.) of the set user equipment (i.e., the first UE to be scheduled above) with the preset threshold, the appropriate uplink receiving beam coverage level is mapped and selected.

[0084] The set UE may be a UE corresponding to the current highest scheduling priority, or may be a certain type of UE, such as all UEs to be scheduled whose belonging beam is the same as the belonging beam of the current highest scheduling priority UE. The signal quality of the UE of this type may be the average signal quality of the UE of this type or the signal quality of the UE with the worst signal quality in the UE of this type.

[0085] For example: Refer to the attached Figure 2 In the example diagram, it is assumed that the signal quality of the UE satisfies: preset threshold 2 < signal quality of the currently scheduled highest priority user ≤ preset threshold 1, then mapping is performed to select uplink receive beam coverage level 2.

[0086] 4. Based on the narrowest downlink transmission beam to which the UE with the current highest scheduling priority belongs (i.e., the belonging beam mentioned above), select the beam containing the narrowest downlink transmission beam coverage from all beams corresponding to the uplink receiving beam coverage level determined in step 3 above as the uplink receiving beam.

[0087] Assume that the narrowest downlink transmission beam to which the UE with the highest scheduling priority belongs and all beams corresponding to the uplink receiving beam coverage level selected in step 3 meet the following conditions: Figure 4 As shown in the coverage relationship, beam 1 in the uplink reception coverage level 2 is selected as the uplink reception beam.

[0088] 5. Based on the correspondence (1 to 1 or 1 to many) between the beam coverage area of the uplink receive beam and the beam coverage area of the narrowest downlink transmit beam, determine the corresponding narrowest downlink transmit beam set when using the uplink receive beam for uplink signal reception.

[0089] Refer to the attached Figure 5As shown in the diagram, assuming that the entire cell area uses the narrowest downlink transmit beam for transmission, the number of corresponding narrowest downlink transmit beams is 16. When beam 1 in uplink reception coverage level 2 is selected as the uplink receive beam, beam 1 in uplink reception coverage level 2 covers 8 narrowest downlink transmit beams. The corresponding set of narrowest downlink transmit beams when using this uplink receive beam for uplink signal reception is: {narrowest downlink transmit beam 1, narrowest downlink transmit beam 2, narrowest downlink transmit beam 3, narrowest downlink transmit beam 4, narrowest downlink transmit beam 5, narrowest downlink transmit beam 6, narrowest downlink transmit beam 7, narrowest downlink transmit beam 8}.

[0090] 6. All UEs whose belonging beam is a beam in the narrowest downlink transmission beam set can be scheduled and use the uplink receive beam to receive uplink signals.

[0091] For example, assuming that there are currently four UEs that need to be scheduled, UE1 belongs to the narrowest downlink transmission beam 1, UE2 belongs to the narrowest downlink transmission beam 8, UE3 belongs to the narrowest downlink transmission beam 9, and UE4 belongs to the narrowest downlink transmission beam 16. Based on the narrowest downlink transmission beam set determined in step 5 above, it can be seen that UE1 and UE2 can be scheduled and transmit data.

[0092] 7. Different uplink receive beam coverage levels correspond to different uplink receive gains. When determining the MCS level for uplink scheduling, different uplink receive gains need to be considered.

[0093] For example, it is assumed that a certain UE is normalized to the uplink reception coverage level 1 beam reception to determine and correct the MCS level, and the determined MCS level is MCSx (ie, the first MCS level mentioned above).

[0094] When the UE currently uses a beam in uplink reception coverage level n for reception, then:

[0095] 1) Obtain the corresponding signal quality SNRx (i.e., the first signal quality mentioned above) according to the MCSx mapping;

[0096] 2) Considering different uplink reception gains, let the reception gain of uplink reception coverage level n compared to uplink reception coverage level 1 be Gain n_vs_1 , then the signal quality SNRy when receiving with the beam in uplink coverage level n is SNRx = (SNRx + Gain n_vs_1 );

[0097] 3) According to the SNRy (i.e., the second signal quality mentioned above), the corresponding MCS level MCSy (i.e., the second MCS level mentioned above) is mapped, and based on the MCS level MCSy, the UE is scheduled to use the beam in the uplink reception coverage level n for uplink signal reception.

[0098] It should be noted that steps 3, 4, and 5 above primarily determine the uplink receive beam and the set of narrowest schedulable downlink transmit beams. In actual implementation, beam determination must be completed before scheduling. Beams can vary based on a set time unit, which can be one or more time slots or one or more symbols. In other words, beams can be determined periodically, with a periodic duration of one or more time slots or one or more symbols.

[0099] Based on the implementation process of the method for determining an uplink receiving beam provided by the embodiment of the present application described in the above embodiment, it can be known that: the basis for determining the uplink receiving beam is to perform uplink receiving coverage level division. Therefore, the following is first combined with the following Figure 6 Describe the specific process of uplink reception coverage level division.

[0100] Assuming that the entire cell area adopts the narrowest downlink transmission beam for transmission, the corresponding number of the narrowest downlink transmission beams is 16, then the maximum coverage level number N is log2(16)+1=5.

[0101] The uplink receive beam coverage levels can be divided into the following categories:

[0102] Uplink receiving beam coverage level 1: One wide beam independently completes uplink signal reception in the entire cell area;

[0103] Uplink receive beam coverage level 2: Two slightly narrow beams independently complete uplink signal reception in the entire cell area;

[0104] Uplink receive beam coverage level 3: 4 narrow beams independently complete uplink signal reception in the entire cell area;

[0105] Uplink receive beam coverage level 4: 8 narrower wide beams independently complete uplink signal reception in the entire cell area;

[0106] Uplink receive beam coverage level 5: 16 narrowest beams independently complete uplink signal reception in the entire cell area.

[0107] like Figure 6 As shown, there is a corresponding relationship between each coverage level and the preset threshold, wherein there are 4 preset thresholds between the 5 coverage levels, and preset threshold 1>preset threshold 2>preset threshold 3>preset threshold 4.

[0108] The uplink reception beam is selected based on the above uplink reception coverage level classification. The specific implementation process can be described in detail through the following embodiments.

[0109] Example 1

[0110] Assume that there are currently five user equipments (UEs) that need to be scheduled. UE1 belongs to the narrowest downlink transmission beam 1, UE2 belongs to the narrowest downlink transmission beam 6, UE3 belongs to the narrowest downlink transmission beam 9, UE4 belongs to the narrowest downlink transmission beam 10, and UE5 belongs to the narrowest downlink transmission beam 16.

[0111] The highest-priority user equipment currently scheduled is UE1, which is located at the best point and has excellent signal quality. UE1's signal quality is greater than a preset threshold 1. UE1 is normalized to uplink reception coverage level 1, with beam reception to determine and correct the MCS level. The determined MCS level is MCSx.

[0112] (11) Compare the signal quality of the currently scheduled highest priority UE with the preset threshold, and then map and select the appropriate uplink receive beam coverage level.

[0113] The UE with the highest scheduling priority currently is UE1, and its signal quality satisfies: UE1's signal quality > preset threshold 1, so uplink receive beam coverage level 1 is selected.

[0114] (12) Based on the narrowest downlink transmission beam to which the UE with the current highest scheduling priority belongs, a beam containing the narrowest downlink transmission beam coverage is selected as the uplink reception beam from among all beams corresponding to the uplink reception beam coverage level 1 selected in (11).

[0115] The UE with the highest scheduling priority currently is UE1, which belongs to the narrowest downlink transmission beam 1, and the uplink reception beam coverage level 1 has only one wide beam (denoted as beam 1). This wide beam coverage includes the coverage of the narrowest downlink transmission beam 1. Therefore, beam 1 in the uplink reception beam coverage level 1 is selected as the uplink reception beam.

[0116] (13) According to the correspondence between the beam coverage area of the uplink receiving beam and the beam coverage area of the narrowest downlink transmitting beam (one to one or one to many), the corresponding narrowest downlink transmitting beam set when the uplink receiving beam is used for uplink signal reception is determined.

[0117] Beam 1 in uplink receive beam coverage level 1 is a wide beam, which covers all 16 narrowest downlink transmit beams. Therefore, when this uplink receive beam is used for uplink signal reception, the corresponding set of narrowest downlink transmit beams is: {narrowest downlink transmit beam 1, narrowest downlink transmit beam 2, narrowest downlink transmit beam 3, narrowest downlink transmit beam 4, narrowest downlink transmit beam 5, narrowest downlink transmit beam 6, narrowest downlink transmit beam 7, narrowest downlink transmit beam 8, narrowest downlink transmit beam 9, narrowest downlink transmit beam 10, narrowest downlink transmit beam 11, narrowest downlink transmit beam 12, narrowest downlink transmit beam 13, narrowest downlink transmit beam 14, narrowest downlink transmit beam 15, narrowest downlink transmit beam 16}.

[0118] (14) All UEs whose belonging beam is a beam in the narrowest downlink transmission beam set can be scheduled and use the uplink receiving beam to receive uplink signals.

[0119] The five UE belonging beams that currently need to be scheduled are all in the downlink transmission narrowest beam set corresponding to the uplink reception beam, so all five user equipments can be scheduled.

[0120] (15) Different uplink receive beam coverage levels correspond to different uplink receive gains. When determining the MCS level for uplink scheduling, different uplink receive gains need to be considered.

[0121] The currently selected uplink receiving beam is a beam in uplink receiving coverage level 1. Therefore, when uplink scheduling determines the MCS level, there is no need to superimpose the uplink receiving gain, that is, Gain_1vs1=0.

[0122] Taking UE1 as an example, UE1 can be scheduled according to MCSx.

[0123] Example 2

[0124] Assume that there are currently five user equipments (UEs) that need to be scheduled. UE1 belongs to the narrowest downlink transmission beam 1, UE2 belongs to the narrowest downlink transmission beam 6, UE3 belongs to the narrowest downlink transmission beam 9, UE4 belongs to the narrowest downlink transmission beam 10, and UE5 belongs to the narrowest downlink transmission beam 16.

[0125] The highest-priority user equipment currently scheduled is UE 5, located at the cell edge and with poor signal quality. The signal quality of UE 5 is less than a preset threshold of 4. UE 5 is normalized to uplink coverage level 1 for medium beam reception, and the MCS level is determined and corrected. The determined MCS level is MCSx.

[0126] (21) Based on the comparison of the signal quality of the UE with the highest priority currently scheduled with the preset threshold, the appropriate uplink receiving beam coverage level is mapped and selected.

[0127] The UE with the highest scheduling priority is UE 5, and its signal quality satisfies: UE5's signal quality < preset threshold 4, so uplink receive beam coverage level 5 is selected.

[0128] (22) Based on the narrowest downlink transmission beam to which the UE with the current highest scheduling priority belongs, a beam containing the narrowest downlink transmission beam coverage is selected as the uplink reception beam from among all beams corresponding to the uplink reception beam coverage level 4 selected in (21).

[0129] The UE with the highest scheduling priority currently is UE5, which belongs to the narrowest downlink transmission beam 16, and there are 16 uplink reception narrow beams in the uplink reception beam coverage level 5. The number of the narrowest uplink reception beams is the same as the number of the narrowest downlink transmission beams, and the beam coverage is reciprocal, that is, the coverage is considered to be the same. Therefore, beam 16 in the uplink reception beam coverage level 5 is selected as the uplink reception beam.

[0130] (23) According to the correspondence between the beam coverage area of the uplink receiving beam and the beam coverage area of the narrowest downlink transmitting beam (one to one or one to many), the corresponding narrowest downlink transmitting beam set when the uplink receiving beam is used for uplink signal reception is determined.

[0131] Beam 16 in the uplink receive beam coverage level 5 is an uplink receive narrow beam, and its coverage is only the same as the coverage of the downlink transmit narrowest beam 16. Therefore, when using this uplink receive beam for uplink signal reception, the corresponding downlink transmit narrowest beam set is: {downlink transmit narrowest beam 16}.

[0132] (24) All UEs whose belonging beam is a beam in the narrowest downlink transmission beam set can be scheduled and use the uplink receiving beam to receive uplink signals.

[0133] Of the five UEs that currently need to be scheduled, only the belonging beam of UE5 is in the narrowest downlink transmission beam set corresponding to the uplink reception beam. Therefore, only UE5 can be scheduled.

[0134] (25) Different uplink receive beam coverage levels correspond to different uplink receive gains. When determining the MCS level for uplink scheduling, it is necessary to consider different uplink receive gains.

[0135] When UE5 currently uses the beam with uplink reception coverage level 5 for reception, then:

[0136] First, the corresponding signal quality SNRx is obtained according to the MCSx mapping;

[0137] Secondly, the uplink reception gain of uplink reception coverage level 5 compared to uplink reception coverage level 1 is considered (Note: the reception gain of uplink reception coverage level 5 compared to uplink reception coverage level 1 is Gain 5_vs_1 ), calculate the signal quality SNRy when using the beam in uplink reception coverage level 5 for uplink signal reception = (SNRx + Gain 5_vs_1 );

[0138] Finally, the corresponding MCS level MCSy is determined based on the signal quality SNRy, and based on the MCS level MCSy, UE5 is scheduled to use the beam in the uplink reception coverage level 5 to receive uplink signals.

[0139] The above two embodiments show that the coverage of the uplink receive beam affects the number of UEs that can be scheduled. When a wide beam is used for uplink signal reception, all UEs can be scheduled; when a narrow beam is used for uplink signal reception, only some UEs can be scheduled.

[0140] Since the location and signal quality of user equipment within a cell may vary, user equipment at the cell edge has poor signal quality. Only narrow-beam reception can correctly receive uplink signals and ensure uplink coverage. For user equipment at the cell center, the signal quality is very good, and either narrow-beam or wide-beam reception can be used.

[0141] By utilizing the solution of the present invention, the uplink receiving beam can be adaptively selected based on the uplink receiving coverage level and the current highest scheduling priority signal quality, thereby taking into account the number of schedulable user equipment and the coverage of user equipment at different locations in the cell.
