Description

A beam adjustment method and device

technical field

The present application relates to the field of communication technologies, and in particular, to a beam adjustment method and apparatus.

Background technique

In order to improve the capacity of users in the communication system and the communication rate of terminal equipment, the 5th generation mobile networks (5G) new radio (NR) system introduces the millimeter wave spectrum. The millimeter-wave spectrum has a large bandwidth and a high data transmission rate. For example, the 28GHz carrier frequency bandwidth can be as high as 800MHz. Compared with the 4th generation mobile communication technology (4G) long term evolution (LTE) system In the 20MHz bandwidth, the transmission rate is up to 40 times.

Although the bandwidth of the millimeter wave spectrum is large, the signal attenuation is large during the transmission process. In order to solve the problem of large attenuation of mmWave signals, multi-input-multi-output (MIMO) is introduced to improve the signal gain. MIMO can improve the gain of the millimeter wave signal and reduce the loss of the signal, but the signal does not have a specified direction during the transmission process, the coordination between multiple antennas is low, and the signals are prone to mutual interference. In order to transmit directional beams, beamforming comes into being. The beamforming includes analog beamforming, digital beamforming and hybrid beamforming. Analog beamforming is to adjust the corresponding phase value of each beam through a phase shifter, so as to form a beam with a certain direction, and the adjusted beam scanning range can cover the terminal equipment in a certain area, and provide the Equipment provides services. However, when the analog beam is formed, the phase adjustment can only be adjusted according to the fixed weighted value of the phase shifter, so that only one analog beam in the frequency band serves the terminal equipment, and the terminal equipment in the analog beam cannot occupy all the frequency domain. resources, so that the frequency domain resources cannot be fully utilized.

detailed description

In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings. The specific operation methods in the method embodiments may also be applied to the apparatus embodiments or the system embodiments. Wherein, in the description of the present application, unless otherwise specified, the meaning of "plurality" is two or more.

In order to better illustrate the solution of the application, the terms used in the application are explained below first:

Network equipment: a node in a radio access network (RAN), also known as a base station, or a RAN node (or device). At present, some examples of access network equipment are: gNB/NR-NB, transmission reception point (TRP), evolved node B (evolved node B, eNB), radio network controller (radio network controller, RNC) ), node B (node B, NB), base station controller (BSC), base transceiver station (base transceiver station, BTS), home base station (for example, home evolved NodeB, or home Node B, HNB), A base band unit (BBU), or a wireless fidelity (Wifi) access point (AP), or a network device in a 5G communication system, or a network device in a possible future communication system, or satellite. The network device may also be other devices with network device functions. For example, the network device may also be a device-to-device (D2D) or machine-to-machine (M2M) communication serving as a network Device-enabled devices, for example, connected car devices. The network device may also be a network device in a possible future communication system.

Terminal device: It can also be called UE, mobile station (MS), mobile terminal (MT), etc. It is a device that provides voice or data connectivity to users, and it can also be an Internet of Things device. For example, the terminal device includes a handheld device with a wireless connection function, a vehicle-mounted device, and the like. At present, terminal devices can be: mobile phones (mobile phones), tablet computers, notebook computers, PDAs, mobile internet devices (MIDs), wearable devices (such as smart watches, smart bracelets, pedometers, etc.) , in-vehicle equipment (for example, cars, bicycles, electric vehicles, airplanes, ships, trains, high-speed rail, etc.), virtual reality (VR) equipment, augmented reality (AR) equipment, industrial control (industrial control) wireless terminals, smart home equipment (such as refrigerators, TVs, air conditioners, electricity meters, etc.), intelligent robots, workshop equipment, wireless terminals in self-driving, wireless terminals in remote medical surgery, A wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, or a wireless terminal in a smart home, flying equipment (for example, Intelligent robots, hot air balloons, drones, airplanes), etc.

Beamforming, also known as beamforming, is a signal processing technology that uses sensor arrays to send and receive signals directionally. By adjusting the parameters of the basic unit of the phased array, signals at certain angles obtain constructive interference, while signals at other angles obtain constructive interference. The signal obtains destructive interference, and beamforming can be used for both the signal transmitter and the signal receiver. In practical applications, including: digital beamforming, analog beamforming and hybrid beamforming. Among them, digital beamforming is to form multiple beams through the regulation of analog-to-digital converters and digital-to-analog converters. When the beam is formed by analog beamforming, a phase shifter is applied. Since the direction of the phase shifter is fixed, only a beam with one direction can be formed.

Resource block (RB): 12 consecutive subcarriers in the frequency domain, and one slot (slot) in the time domain is 1 RB.

Resource element (resource element, RE): a subcarrier in the frequency domain and a symbol (symbol) in the time domain, it is an RE.

It should be noted that the beamforming in 4G is realized by digital beamforming, and there can be multiple digital beams with different directions in a slot or a symbol, so that each beam can Fully occupy the frequency domain resources, as shown in Figure 1. Among them, beam 1 is indicated by the diagonal line in the lower left, beam 1 can serve UE1, and the occupied frequency domain resources are also indicated by the diagonal line in the lower left; Beam 2 is indicated by the grid line, and beam 2 can serve UE2, occupying The frequency domain resources of 1 are also indicated by grid lines; Beam 3 is indicated by the lower right slashes, beam 3 can serve UE3, and the occupied frequency domain resources are also indicated by the lower right slashes. Multiple UEs can be scheduled in one time slot. Since there may be multiple digital beams in one time slot in 4G, UEs can be fully scheduled under different digital beams, so the frequency domain resources corresponding to the slot can be fully utilized in 4G.

However, in 5G, the phase shifter is used to adjust the phase of the analog beam to perform beamforming. The analog beamforming can only obtain the beam in one direction, so one time slot or one symbol or multiple time slots or more There is only one beam within a symbol. The UE corresponding to one beam may not be able to fully utilize the frequency domain resources corresponding to each time slot, and resources may be wasted, as shown in FIG. 2 . Among them, beam 1 is indicated by the lower right slash, beam 1 can serve UE1, and the occupied frequency domain resources are also indicated by the lower left slash, UE1 can only occupy part of the frequency domain resources, so that there are a lot of frequency domain resources The remaining frequency domain resources cannot be fully utilized.

In addition, when using analog beamforming, if the base station needs to schedule two UEs in the PDCCH, and the two UEs receive services under different analog beams, because different analog beams occupy different symbol resources, two different analog beams The beam needs to occupy two orthogonal frequency division multiplexing (orthogonal frequency division multiplexing, OFDM) symbols, as shown in FIG. 3 . Among them, beam 0 corresponding to UE0 is indicated by slashes, and beam 0 occupies symbol 0, which is also indicated by slashes; beam 1 corresponding to UE1 is indicated by grid lines, and beam 1 occupies symbol 1, which is indicated by grid lines. Two beams need to occupy 2 OFDM symbols overhead. If the base station performs beam scheduling in the PUCCH, the overhead of 2 OFDM symbols is also required. Wherein, beam 0 corresponding to UE0 is indicated by a slash, and beam 0 occupies symbol 12; beam 1 corresponding to UE1 is indicated by grid lines, and beam 1 occupies symbol 13.

Therefore, it can be seen that when different UEs are scheduled through different analog beams, the OFDM symbol overhead will increase. For example, in the PDCCH, UE0 performs downlink scheduling through beam 0, and UE1 performs uplink scheduling through beam 1, which requires 2 OFDM symbols overhead; If in DDDSU (downlink slot/downlink slot/downlink slot/Special Slot/Uplink Slot), each D slot needs to correspond to an uplink acknowledgement (acknowledge, ACK)/non-acknowledgement (negative acknowledgement, NACK), and each D The analog beams scheduled on the slot are all different, and a maximum of 4 OFDM symbols need to be allocated on the U slot. Therefore, when using analog beamforming, the symbol overhead in the time domain is very large, but in practical applications, the above D slot It may correspond to one analog beam, then only one OFDM symbol needs to be allocated on the U slot.

Based on this, the present application provides a beam adjustment method to improve resource utilization. The solution provided in this application can be applied to 4G, 5G, or higher standard communication technology, which is not specifically limited in this application.

FIG. 4 shows a schematic diagram of a network architecture applicable to the beam adjustment method provided by the present application provided by an embodiment of the present application. The network architecture includes a baseband processing unit (building baseband unit, BBU) and an active antenna unit (active antenna unit, AAU). Among them, the BBU is mainly used for channel codec, baseband signal modulation and demodulation, protocol processing and other functions. AAU mainly completes RF signal modulation and demodulation, RF analog signal power amplification, and beam transmission, so as to provide services for terminal equipment. The network architecture can transmit data through the interface protocol of common public radio interface (CPRI), and can also transmit data through the interface protocol of enhanced common public radio interface (eCPRI). No specific limitation is made.

FIG. 5 shows a schematic flowchart of the beam adjustment method provided by the present application, and the network device may refer to the following steps to perform:

Step 501: Determine the number of resources and signal quality occupied by each terminal device in the plurality of terminal devices when receiving the service under the first analog beam.

Step 502: Determine the number of resources and signal quality occupied by each terminal device when receiving the service under the second analog beam according to the number of resources and signal quality occupied by each terminal device when receiving the service under the first analog beam.

Step 503, when the sum of the number of resources occupied by each terminal device when receiving the service under the second analog beam is less than the total number of carrier resources, and the signal quality of each terminal device when receiving the service under the second analog beam is greater than the preset value. If the threshold is set, the second analog beam is used to serve multiple terminal devices; wherein, the radiation area of the second analog beam is larger than the radiation area of the first analog beam.

It should be noted that, in the above step 501, there may be multiple terminal devices in the area radiated by the first analog beam emitted by the network device, but only the terminal device that has data interaction with the network device can determine the number of resources occupied by it. and signal quality. For example, the first analog beam 1 radiates area 1, and area 1 includes UE, MS, MT, tablet computer, and handheld computer, but in area 1, only UE and tablet computer have data interaction with network equipment, so network equipment The number of resources and signal quality occupied by the UE and the tablet can be determined.

In the above step 501, when each terminal device receives the service under the first analog beam, the number of resources occupied and the signal quality can be indicated by different information in different channels of the network device, such as: in the PDCCH through each terminal device The corresponding CCE aggregation level is used to determine the number of resources occupied by the terminal equipment and the signal quality. It should be noted that the CQI is used to indicate the channel quality. Since the CCE aggregation level is determined by the MCS corresponding to the downlink CQI, for example, CQI15 corresponds to the MCS2 level, and the MCS2 level corresponds to the CCE aggregation level of 6, so it can be understood as through the CCE The aggregation level indicates the signal quality, and the information used to indicate the number of resources and the signal quality in other channels will not be described one by one here.

The above steps 502 and 503 can be understood that the network device obtains the number of resources and signal quality occupied by each terminal device when receiving services under the first analog beam, and pre-calculates according to the number of resources occupied by each terminal device and the signal quality. , determine whether these terminal devices can still receive communication services under the second analog beam after changing the first analog beam into the second analog beam, and if so, serve these terminal devices through the second analog beam. In order to illustrate the solution of the present application more vividly, the following example is used to illustrate that in the area 1 covered by the first analog beam 1, there are UE1, UE2 and UE3 in the area 1, and UE1, UE2 and UE3 are all devices to be scheduled (that is, There is a terminal device for data interaction with the network equipment, which will not be described below); the area 2 covered by the first analog beam 2, there are UE4 and UE5 in the area 2, and UE5 is the equipment to be scheduled; the first analog beam 3 covered under In area 3, UE6 exists in area 3, and UE,6 is a device to be scheduled. The network device may acquire the number of resources and signal quality occupied by UE1, UE2, UE3, UE5 and UE6. If the network device determines through budget that the sum of the resources occupied by UE1, UE2, UE3, and UE5 is less than the total number of carrier resources, and the signal quality is greater than the preset threshold, the first analog beam 1 and the first analog beam are replaced by the second analog beam. Beam 2 provides services for UE1, UE2, UE3, and UE5. The replacement here can be understood as broadening the first analog beam 1 and the first analog beam 2 to obtain the second analog beam, which can also be understood as directly passing a radiation area. A large beam is used to replace the first analog beam 1 and the first analog beam 2, which is not specifically limited in this application.

In addition, it should be noted that, in practical applications, other first analog beams may also be included. Although the UE3 under the first analog beam 3 in the above example fails to receive services under the second analog beam, the network device may also The number of resources occupied by the terminal equipment under the first analog beam and the number of resources occupied by UE3 are budgeted, and it is determined whether the sum of the occupied resources is less than the total number of carrier resources, and the signal quality is greater than the preset threshold. A second analog beam serves these UEs.

In this application, when the network device determines that the sum of the resources occupied by multiple terminal devices is less than the total number of carrier resources, and the signal quality is greater than the preset threshold, the second analog beam with a larger radiation area serves the terminal device, Compared with the first analog beam with a smaller radiation area, this method can cover more terminal devices and make more full use of frequency domain resources. In addition, because different first analog beams may occupy multiple time domain symbols resource, the present application uses the second analog beam with a larger radiation area to serve the terminal equipment, which can reduce the symbol overhead of time domain resources.

In one embodiment, if the sum of the number of resources occupied by the devices to be scheduled under the first analog beam 1 and the devices to be scheduled under the first analog beam 2 is less than or equal to the total number of resources, and the number of resources under the first analog beam 1 If the signal quality of the device to be scheduled and the device to be scheduled under the first analog beam 2 are both greater than the preset threshold, the second analog beam is used to schedule the device to be scheduled under the first analog beam 1 and the first analog beam 2 .

For example, if the first analog beam 1 and the first analog beam 2 are adjacent beams, the first analog beam 1 and the first analog beam 2 can be combined into one under the precondition that the device to be scheduled satisfies the above conditions. The wide beam is also the second analog beam, and the second analog beam has a peak; if the first analog beam 1 and the first analog beam 2 are not adjacent beams, then on the premise that the equipment to be scheduled satisfies the above conditions, The first analog beam 1 and the first analog beam 2 can be combined into one wide beam, that is, the second analog beam, that is, the second analog beam has multiple peaks.

In addition, in different time slots or symbols, different analog beams may be included, and these analog beams will occupy different frequency domain resources, and the corresponding carriers of different physical channels may be different, so the total number of resources of the corresponding carriers is also For example, the carrier bandwidth in the PDCCH is 200MHz, and when the subcarrier space (SCS) is 120kHz, the corresponding number of resources is 132RB (because the 5G protocol stipulates that the protection bandwidth needs to be reserved, and the protection bandwidth is 5MHz). When 200MHz is approximately equal to 132RB*12*120kHz+5*2MHz); the carrier bandwidth in PUCCH is AMHz, and when SCS is xkHz, the corresponding number of resources is WRB (because the 5G protocol stipulates that the protection bandwidth needs to be reserved, in the When the guard bandwidth is 5MHz, AMHz is approximately equal to WRB*12*xkHz+5*2MHz). If different time slots correspond to different first analog beams, it can be calculated according to the number of resources occupied by the devices to be scheduled served by the first analog beam, and it is determined that if the first analog beam is widened into the second analog beam, the device to be scheduled 1 Whether the occupied resources are less than or equal to the total number of resources of the carrier, if it is less than, then determine whether the remaining total resources can still satisfy the other devices to be scheduled 2 under the first analog beam to receive services under the second analog beam, if it can meet the demand , then the device to be scheduled 1 and the device to be scheduled 2 are served through the second analog beam.

In addition, it should be noted that the terminal equipment served by the analog beam in this application may be constantly changing, and can be flexibly converted into the first analog beam or the second analog beam to serve the terminal equipment according to the actual needs of the terminal equipment. For example, terminal device 1 receives services under the second analog beam, but terminal device 1 needs to perform some special tasks, such as: running games and playing ultra-high-definition videos. At this time, terminal device 1 needs higher signal quality. Obviously, the receiving service under the second analog beam cannot meet the service requirements of the terminal device 1, so the terminal device 1 can be served through the first analog beam.

In addition, in some special scenarios, the second analog beam can be used to serve the terminal equipment directly, and it is not necessary that the number of resources occupied by the terminal equipment and the signal quality meet the conditions in the above step 503 . This special scenario can include: confined small-scale spaces, such as canteens, basketball courts, office buildings, etc., can directly use the second analog beam to provide services for the UE, and the width of the second analog beam can be determined according to the width of the terminal equipment in different scenarios. The number can also be determined by other parameters in different scenarios, such as services performed by the terminal device, etc., which is not specifically limited in this application.

In order to better illustrate the solution of the present application, the solution of the present application will be described in detail below in different physical channels in combination with specific embodiments. However, in practical application, in addition to the following physical channels, the solution provided by the present application It can also be applied to other physical channels, which is not specifically limited here:

Case 1. The network device performs beam adjustment in the PDCCH

It should be noted that when the beam adjustment scheme in Case 1 is implemented, in the PDCCH, the number of resources and the signal quality may be indicated by one or more of the following first information, where the first information includes: CCE aggregation level, or downlink CQI, or MCS of PDSCH; then the network device determines, according to the first information, the number of resources occupied and the signal quality of each terminal device when receiving services under the second analog beam.

The network device determines that the sum of the corresponding resource numbers after the first analog beam corresponding to each terminal device is broadened to the second analog beam is less than the total number of resources of the carriers in the PDCCH, then determines that the first analog beam corresponding to each terminal device is broadened as the second analog beam. After beaming, the signal quality of each terminal device; if it is determined that the signal quality of each of the terminal devices is greater than a preset threshold, the second analog beam is used to serve a plurality of the terminal devices. The following uses the CCE aggregation level as an example, but in practical applications, it can also be indicated by MCS or CQI. The CQI can feed back the quality of the channel, and the order corresponding to the corresponding MCS can be determined based on the value of the CQI, and then the CCE aggregation level corresponding to the terminal device can be determined by the order of the MCS.

The carrier of the network device in the PDCCH may be a millimeter wave, or a beam of other frequency bands, which is not specifically limited in this application. In addition, according to the scheduling priority of each terminal device, the number of resources and signal quality required by each terminal device after the first analog beam corresponding to each terminal device is widened into the second analog beam can be sequentially determined. For example, the network device will acquire the beam identity document (ID) of the first analog beam serving each terminal device, the scheduling priority corresponding to each terminal device, and the CCE aggregation level corresponding to each terminal device, and maintain the above-mentioned first a message. The network device can store the above-mentioned first information so as to adjust the beam width according to the first information. In practical application, a table similar to Table 1 can be maintained in the network device, and the above-mentioned first information can also be stored in other storage forms. information, and each information in the first information can also be stored after being set according to a preset coding rule, which is not specifically limited in this application. Table 1 shows the scheduling priorities, corresponding first analog beam identifiers, and CCE aggregation levels corresponding to each UE. In practical application, only some rows or columns in Table 1 are applied, which are not specifically limited here. In addition, in the solution of the present application, the CCE aggregation level may indicate the resource occupation of the UE. Among them, one CCE contains 6 REGs, and one REG corresponds to one RB; the larger the value corresponding to the scheduling priority, the lower the scheduling priority.

Table 1

It should be noted that it is assumed that the first analog beam 0 can serve multiple UEs, including: UE0, UE1, UE5, UE7, and UE9. However, only UE0 and UE1 have data interaction with the network device, that is, scheduling is required, and the network device maintains the CCE aggregation levels corresponding to UE0 and UE1. It is assumed that the first analog beam 1 can serve multiple UEs, including: UE2, UE3, UE4, UE6 and UE8. However, only UE2 and UE3 have data interaction, that is, scheduling is required, and the network device maintains the CCE aggregation levels corresponding to UE2 and UE3. In addition, the information in Table 1 is maintained and changed dynamically in real time. If UE5 under the first analog beam 0 also has data interaction with the network device, the CCE aggregation level corresponding to UE5 is also added to Table 1, or the An analog beam 0 and a first analog beam 1 are widened into a second analog beam A, and the second analog beam A provides services for UE0-UE3 at the same time, then the first analog beam 0 and the first analog beam 1 in Table 1 are updated to A second analog beam A.

In addition, if the carrier in the PDCCH is a millimeter wave, and the bandwidth of the millimeter wave is 200MHz and the SCS is 120kHz, then the number of resources corresponding to the millimeter wave is 132RB. According to Table 1, it can be known that UE0 has the highest scheduling priority, and the CCE aggregation level corresponding to UE0 is 4CCE, that is, occupies 24RBs (4*6RBs). In order to ensure that UE0 can demodulate PDCCH under the second analog beam, when determining the number of resources required by UE0 under the second analog beam, it can be determined by increasing the CCE aggregation level corresponding to UE0 by 2 times, such as: UE0 The corresponding CCE aggregation level is raised from 4CCE to 8CCE. At this time, it is determined by calculation that the number of resources required by UE0 under the second analog beam is 48 RBs (8*6RB), so that it can be guaranteed that UE0 can receive services under the second analog beam. It should be noted that, after each UE corresponding to the first analog beam is widened into the second analog beam, the corresponding number of resources can be set according to the actual application, which is not specifically limited in this application. It can be twice the number of resources occupied by the UE before the beam broadening, or it can be the number of resources occupied by the UE before the beam broadening plus a specific value.

Assuming that the first analog beam 0 corresponding to UE0 occupies 48 RBs after being widened, it can be seen from calculation that 48 RBs is much smaller than the number of resources corresponding to millimeter waves, 132 RBs. Under the first analog beam 0, there is still UE1 performing scheduling. After calculation, it can be known that after the first analog beam 0 is widened, the number of resources occupied by UE1 is also 48RB. After the UE under the first analog beam 0 is scheduled, there are still millimeter-wave resources remaining, and the remaining 36RB (132RB-48RB-48RB). The network device first determines the number of resources occupied by the beam 1 corresponding to UE2 after widening according to the scheduling priority. After calculation, it can be known that the number of resources occupied by UE2 is 24RB (4*6RB), and 24RB is less than 36RB. At this time, there are still 12 RBs (132RB-48RB-48RB-24RB) of millimeter-wave resources remaining, but the remaining 12RB resources are not enough for UE3 under the first analog beam 1 to demodulate the PDCCH (due to the CCE aggregation corresponding to UE3). The level is 2CCE. After the first analog beam 1 is widened, 24 RBs (4*6 RBs) are required to demodulate the PDCCH, but the remaining millimeter-wave resources are only 12 RBs, so the widened beam cannot serve UE3). Therefore, the first analog beam 0 and the first analog beam 1 are widened into a wide beam (beam A) to serve UE0, UE1, and UE2, and the same PDCCH OFDM symbol can be used for scheduling for UE0, UE1, and UE2, obviously. Reduce the symbol overhead in the time domain. In addition, providing services to the UE through a broadened second analog beam also fully utilizes the frequency domain resources of the millimeter wave.

In addition, in order to show the solution in this application more vividly, please refer to the schematic diagram shown in FIG. 6 , in which the network device sends the first analog beam 0 at time 1 and the first analog beam 1 at time 2, and the network device sends the first analog beam 1 at time 2. UE0 needs to be scheduled under beam 0, UE1 needs to be scheduled under first analog beam 1, UE0 occupies OFDM symbol 0, and UE1 occupies OFDM symbol 1. In FIG. 6 , the first analog beam 0 is indicated by the lower right oblique line, the first analog beam 1 is indicated by the grid line, and the second analog beam A is indicated by the horizontal line. After the network device widens the first analog beam 0 and the first analog beam 1 into the second analog beam A, the sum of the resources occupied by the UE0 and the UE1 does not exceed the total number of resources of the carrier, and the first analog beam 0 and the first analog beam After the analog beam 1 is widened into the second analog beam A, the signal quality of UE0 and UE1 is degraded, but it is enough to demodulate the PDCCH, then the extended second analog beam A provides services for UE0 and UE1, and UE0 and UE1 only occupy 1 symbol resources in the frequency domain, that is, OFDM symbol 0.

In addition, in practical application, if the signal quality of the UE is sufficient to demodulate the PDCCH, the extended second analog beam can be used to serve multiple UEs. In another example, the beam ID of the beam served by each terminal device maintained by the network device in real time, the scheduling priority corresponding to each terminal device, and the CCE aggregation level corresponding to each terminal device may be as shown in Table 2 below. Only some rows or columns in Table 2 are applied, and no specific limitation is made here.

Table 2

If the bandwidth of the millimeter wave is 200MHz, the number of resources corresponding to SCS 120kHz is 132RB. According to the scheduling priority, the remaining resources of the network device when the first analog beam 0 is widened are 12RB (132RB-4*2*6RB-6*2*6RB) ), in the case where the first analog beam 0 is widened, the remaining resources 12RB are not enough to enable the UE under the first analog beam 1 to demodulate the PDCCH when the first analog beam is widened, so the first analog beam 0 and the first analog beam 1 cannot be formed into a second analog beam. However, after calculating the first analog beam 2 corresponding to UE4, the resources required after widening are 12RB (1*2*6RB). At this time, the remaining resources of millimeter waves can be fully utilized by UE4. Therefore, the first analog beam 0 and The first analog beam 2 can be expanded into a wide beam (the second analog beam B), but since the first analog beam 0 and the first analog beam 2 are not adjacent beams, the second analog beam is a multi-peak beam, such as shown in Figure 7. In FIG. 7 , the network device sends the first analog beam 0 at time 1, the first analog beam 1 at time 2, and the first analog beam 2 at time 3, and UE0 and UE1 need to be scheduled under the first analog beam 0 , UE2 needs to be scheduled under the first analog beam 1, and UE4 needs to be scheduled under the first analog beam 2. UE0 and UE1 occupy OFDM symbol 0, UE1 occupies OFDM symbol 1, and UE4 occupies OFDM symbol 2. In FIG. 7 , the first simulated beam 0 is indicated by the lower right slash, the first simulated beam 1 is indicated by the grid line, the first simulated beam 2 is indicated by the high-density black dots, and the second simulated beam is indicated by the low-density black dots B. After the network device widens the first analog beam 0 and the first analog beam 2 into the second analog beam B, the sum of the resources occupied by the UE0 and the UE1 does not exceed the total number of resources of the carrier, and the first analog beam 0 and the first analog beam After the analog beam 2 is widened into the second analog beam B, the signal quality of UE0, UE1, and UE4 is degraded, but the signal quality is sufficient to demodulate the PDCCH. UE1 and UE4 only occupy one symbol resource in the frequency domain, that is, OFDM symbol 0 .

In addition, it should also be noted that if the number of resources occupied by the terminal device is greater than the number of resources of the beams sent by the network device, the first analog beam corresponding to the UE is not widened. It is assumed that the highest scheduling priority of UE0 is 1, and its corresponding CCE aggregation level is 16CCE, that is, 96RB (16*6RB) resources are occupied. However, if the beam corresponding to UE0 is widened, the signal quality of the beam will also decrease. In order to ensure that UE0 can demodulate the PDCCH, the CCE aggregation level corresponding to UE0 needs to be improved. For example, the CCE aggregation level corresponding to UE0 is increased to 32CCE, but the resource corresponding to 32CCE is 192RB (32*6RB). Obviously, 192RB is greater than the total number of resources of the carrier, 132RB, and the total number of resources of the carrier is not enough for the widened beam of UE0. In addition, the PDCCH demodulation capability of UE0 decreases after beam broadening, so the beam corresponding to UE0 cannot be broadened.

Case 2. The network device performs beam adjustment in the PUCCH

It should be noted that when the beam adjustment scheme in Case 2 is implemented, in the PUCCH, the number of resources and the signal quality may be indicated by one or more of the following first information, where the first information includes: a reference signal The SINR of the PUSCH, or the MCS of the PUSCH; then the network device determines, according to the second information, the number of resources occupied and the signal quality of each terminal device when receiving the service under the second analog beam.

The network device determines that the sum of the corresponding resource numbers after the first analog beam corresponding to each terminal device is widened to the second analog beam is less than the total number of resources of the carriers in the PUCCH, then determines that the first analog beam corresponding to each terminal device is widened as the second analog beam. After beaming, the signal quality of each terminal device; if it is determined that the signal quality of each of the terminal devices is greater than a preset threshold, the second analog beam is used to serve a plurality of the terminal devices. It should be noted that the network device can also sequentially determine the number of resources and signal quality required by each terminal device after the first analog beam corresponding to each terminal device is widened to the second analog beam according to the scheduling priority of each terminal device. For example, the network device will acquire the beam ID of the first analog beam serving each terminal device, the scheduling priority corresponding to each terminal device, and the SRS SINR corresponding to each terminal device, and maintain the above-mentioned second information in real time. The network device can store the above-mentioned second information so as to adjust the beam width according to the information. In practical applications, a table similar to Table 3 can be maintained in the network device, and the above-mentioned first information can also be stored in other storage forms. The information in the first information can also be stored after being set according to a preset coding rule, which is not specifically limited in this application. Table 3 shows the corresponding scheduling priorities, corresponding beam identifiers, and SRS SINR values of each UE. In practical application, only some rows or columns in Table 3 are applied, which are not specifically limited here.

table 3

It should be noted that it is assumed that the first analog beam 0 can serve multiple UEs, including: UE0, UE1, UE5, UE7, and UE9. However, only UE0 and UE1 have data interaction with the network device, that is, scheduling is required, and the SRS SINRs corresponding to UE0 and UE1 are maintained. It is assumed that the first analog beam 1 can serve multiple UEs, including: UE2, UE3, UE6 and UE8. However, only UE2 and UE3 have data interaction, that is, scheduling is required, and the SRS SINRs corresponding to UE2 and UE3 are maintained. In addition, the information in Table 3 is maintained and changed dynamically in real time, which is not described in detail here, and can refer to the description in the PDCCH.

In addition, if the bandwidth of the carrier is 200MHz and the SCS is 120kHz, the number of resources corresponding to the carrier is 132RB. According to Table 3, it can be seen that UE0 has the highest scheduling priority, and UE0 corresponds to the first analog beam 0. The network device needs to determine whether the number of resources required by UE0 after the first analog beam is widened is less than 132 RBs, and if not, beam 0 is not widened. If the number of resources required by UE0 after the first analog beam is widened (for better description, it is assumed that the number of resources is 96 RBs) is less than 132 RBs, it needs to be determined according to the value A0 of the SRS SINR corresponding to UE0 in the PUCCH, the signal of UE0 quality. If the signal quality of the UE0 is higher than the minimum signal quality corresponding to the demodulated PUCCH than the preset value, it is determined that the UE0 can receive the service in the extended second analog beam. The preset value is determined according to the sum of the decibel (dB) number of the signal drop after beam broadening and the protection margin. Assuming that the signal decreases by 3dB after the first analog beam broadening, the preset value is 3dB+protection margin .

Next, it is judged whether the number of resources required by UE1 after the first analog beam is broadened is less than 36RB (132RB-96RB). , it is determined that the UE1 can receive the service under the extended second analog beam. If the resources of the carrier still exist after the first analog beam 0 is widened, determine whether the UE2 and UE3 under the first analog beam 1 need less resources after the first analog beam 1 is widened than after the first analog beam 0 is widened. , the remaining resources of the carrier, if yes, determine whether the signal quality of UE2 and UE3 is higher than the minimum signal quality corresponding to the demodulated PUCCH by a preset value. If the signal quality of UE2 and UE3 is higher than the minimum signal quality corresponding to the demodulated PUCCH by a preset value, then it is determined whether the resources required after the first analog beam 2 is widened are less than the first analog beam 0 and the first analog beam 1 are widened. Then, the remaining resources of the carrier, if not, the first analog beam 0 and the first analog beam 1 are expanded into a wide beam, that is, the second analog beam provides services for UE0-UE3, and provides a PUCCH OFDM for UE0-UE3 Symbol overhead. It should be noted that the broadened beam is similar to the second analog beam A provided in FIG. 6 .

In addition, if it is determined that after the first analog beam corresponding to the terminal equipment is widened, the number of resources occupied by the UE under the first analog beam is less than the number of resources of the carrier, then it is determined in turn that the terminal equipment under the other first analog beams is in the beam The number of resources occupied after the widening and the signal quality are determined until it is determined that the number of millimeter-wave resources is occupied, or the remaining resources are not enough for the terminal equipment in other first analog beams to demodulate the PUCCH in the widened beam. When the first simulated beam is widened, it may occur that the non-adjacent beams shown in FIG. 7 are widened into multi-peak beams when the beam is widened.

Case 3. The network equipment is adjusted in the PDSCH/PUSCH beam

It should be noted that when the beam adjustment scheme in Case 3 is implemented, in PDSCH, the number of resources and signal quality may be indicated by one or more of the following third information, where the third information includes: MCS or RSPR or uplink CQI; then the network device determines, according to the third information, the number of resources occupied and the signal quality of each terminal device when receiving the service under the second analog beam.

The network device determines that the sum of the corresponding resource numbers after the first analog beam corresponding to each terminal device is broadened to the second analog beam is less than the total number of resources of the carriers in the PDSCH, then determines that the first analog beam corresponding to each terminal device is broadened as the second analog beam. After beaming, the signal quality of each terminal device; if it is determined that the signal quality of each of the terminal devices is greater than a preset threshold, the second analog beam is used to serve a plurality of the terminal devices.

In addition, in the PUSCH, the number of resources and signal quality may be indicated by one or more of the following third information, where the fourth information includes: MCS, RSPR, or downlink CQI; The number of resources and signal quality occupied by the terminal device when receiving the service under the second analog beam.

The network device determines that the sum of the number of resources corresponding to the first analog beam broadening corresponding to each terminal device is smaller than the total number of resources of the carriers in the PUSCH, then determines that the first analog beam broadening corresponding to each terminal device is the second analog beam. After beaming, the signal quality of each terminal device; if it is determined that the signal quality of each of the terminal devices is greater than a preset threshold, the second analog beam is used to serve a plurality of the terminal devices.

Since the situations of PDSCH and PUSCH are relatively similar, the following description takes PDSCH as an example, and the third indication information is MCS. It should be noted that the network device can also sequentially determine the number of resources and signal quality required by each terminal device after the first analog beam corresponding to each terminal device is widened to the second analog beam according to the scheduling priority of each terminal device. For example, the network device will obtain the beam ID of the first analog beam serving each UE, the scheduling priority corresponding to each UE, and the signal quality corresponding to each UE. The signal quality can be indicated by MCS or RSRP, and the network device maintains real-time maintenance. The above third information. The network device can store the above-mentioned third information so as to adjust the beam width according to the third information. In practical applications, a table similar to Table 4 can be maintained in the network device, and the above-mentioned first information can also be stored in other storage forms. information, and each information in the first information can also be stored after being set according to a preset coding rule, which is not specifically limited in this application. Table 4 shows the scheduling priority corresponding to each terminal device, the corresponding beam identifier and the value of the MCS. In practical application, only some rows or columns in Table 4 are applied, which are not specifically limited here.

Table 4

It should be noted that if the bandwidth of the carrier is 200MHz and the SCS is 120kHz, then the number of resources corresponding to the carrier is 132RB. According to Table 4, it can be seen that the scheduling priority of UE0 is the highest, the scheduling priority is 1, and the first analog beam corresponding to UE0 is 0. The network device needs to determine whether the number of resources required by UE0 after the first analog beam is widened is less than 132RB, if not less than , the first analog beam 0 is not broadened. If the number of resources required by the UE0 after the first analog beam is widened (for better description, it is assumed that the number of resources is 96 RBs) is less than 132 RBs, the signal quality of the UE0 in the PDSCH needs to be determined according to the value of the MCS corresponding to the UE0. If the first analog beam 0 is widened into the second analog beam, the signal quality will decrease by the preset value, then the value of the MCS corresponding to UE0 changes from B0 to B0', where B0 is greater than B0', and the preset value is based on the first analog beam. It is determined by the sum of the number of dB of signal drop and the protection margin after an analog beam broadening. Assuming that the signal drops by 3dB after the first analog beam is widened, the preset value is 3dB+protection margin. It is determined in turn that the number of resources required by UE1 and UE2 when the first analog beam is widened, and whether the signal quality is greater than the minimum signal quality required for demodulation of the PDSCH by a preset value. If so, the first analog beam 0 and the first analog beam 1 are formed into a wide beam and the second analog beam provides services for UE0-UE2. The broadened beam The second simulated beam is similar to the wide beam provided in Figure 6.

In addition, if it is determined that after the first analog beam corresponding to the UE is widened, the number of resources occupied by the UE under this beam is less than the number of resources of the carrier, then it is determined in turn that the UEs under the other first analog beams are after the first analog beam is widened. The number of occupied resources and the signal quality are determined until it is determined that the number of millimeter-wave resources is occupied, or the remaining resources are not enough for the UE to demodulate the PDSCH in the broadened beam under other first analog beams. When the first simulated beam is widened, it may occur that the non-adjacent beams shown in FIG. 7 are widened into multi-peak beams when the beam is widened.

In this application, the network device can refer to the above different situations, obtain corresponding information in different physical channels, and determine the number of resources occupied by each terminal device and the corresponding signal quality according to the corresponding information, and then determine a plurality of When the sum of the resources occupied by the terminal equipment is less than the total number of carrier resources, and the signal quality is greater than the preset threshold, the terminal equipment is served by the second analog beam with a larger radiation area. Compared with the first analog beam with a smaller radiation area, this method can cover more terminal devices and make more full use of frequency domain resources. In addition, the first analog beam with a smaller radiation area may occupy multiple For the symbol resources in the time domain, the present application uses the second analog beam with a larger radiation area to serve the terminal equipment, which can reduce the symbol overhead of the time domain resources.

In one embodiment, on an uplink channel such as PUCCH or PUSCH, the signal quality of the terminal equipment can be determined through SRS. For specific implementation, the following examples can be referred to. The network equipment first obtains the service for each UE when performing detection through SRS. The beam ID of the beam, the scheduling priority corresponding to each UE, and the number of resources occupied by each UE, the occupied resources can be determined by the information fed back by SINR or RSPR, and the network equipment maintains the above information in real time. The network device may store the above information so as to adjust the beam width according to the information, and may store the information in the manner shown in Table 5. Table 5 shows the corresponding scheduling priorities, corresponding beam identifiers and SINR values of each UE. When measuring PUCCH and PUSCH signals, you can refer to the results of signal measurement in SRS. In practical applications, only the values in Table 5 are used. Some rows or columns are not specifically limited here.

table 5

According to Table 5, it can be seen that UE0 has the highest scheduling priority, the scheduling priority is 1, and the beam corresponding to UE0 is 0. The network device needs to determine whether the number of resources required by UE0 is less than the preset number of resources (the number of resources includes the number of RE resources and/ or the number of code division resources).

The network device can pre-schedule UE0 and UE1. If it is determined that the number of resources required by UE0 and UE1 is less than the preset number of resources, and when pre-scheduling UE2, the number of resources required by UE2 is also less than the preset number of resources, then UE0 -UE2 can write and receive services in the second analog beam, and can allocate one symbol resource for UE0-UE2. If the network device obtains the SINR according to the SRS measurement corresponding to UE0, it is denoted as C0. The SINR is obtained according to the SRS measurement corresponding to the UE1, which is denoted as C1. The SINR is obtained according to the SRS measurement corresponding to UE2, which is denoted as C2. In PUSCH, if the network equipment uses the first analog beam to receive the SRS, the SINR corresponding to each UE needs to be corrected (because the beam used in the SRS is different from the PUSCH beam), C0'=C0+preset value; when the network equipment uses the second analog beam The beam receives the SRS, and the SINR corresponding to each UE does not need to be modified (because the beam used in the SRS is the same as that used in the PUSCH). Wherein, the preset value is determined according to the sum of the number of dB of signal reduction after beam broadening and the protection margin.

When the signal quality of each of the terminal devices is greater than the preset threshold, a second analog beam is used to serve multiple terminal devices; wherein the radiation area of the second analog beam is larger than the radiation area of the first analog beam .

In a possible implementation manner, the second analog beam has one or more peaks.
