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

[0061] The embodiment of the present application provides a resource scheduling method and device, which performs time-frequency resource scheduling under each beam group, so that the resource scheduling processing particles are reduced to the range of the beam group, thereby refining the resource scheduling processing granularity. Among them, the method and the device are based on the same application concept. Since the principles of solving the problem by the method and the device are similar, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0062] The resource scheduling method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown in FIG. , the terminal 100 and the network device 200 perform data communication via a wireless system.

[0063] The technical solution provided in the embodiment of the present application can be applicable to a variety of systems. For example, the applicable system may be a long term evolution (LTE) system, an LTE frequency division duplex (FDD) system, an LTE time division duplex (TDD) system, an advanced long term evolution (LTE-A) system, a universal mobile telecommunication system (UMTS), a worldwide interoperability for microwave access (WiMAX) system, a 5G new air interface (NR) system and its evolved communication system, etc. These various systems may 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.

[0064] The terminal device involved in the embodiments of the present application may be referred to as a terminal, and may be a device that provides voice and / or data connectivity to the terminal, a handheld device with a wireless connection function, or other processing devices connected to a wireless modem. In different systems, the names of terminal devices may also be different. For example, in a 5G system, the terminal device may be referred to as a user equipment (UE). A wireless terminal device may be a USB storage device, other personal computer memory devices, and a dongle, or may communicate with one or more core networks (CN) via a radio access network (RAN). A wireless terminal device may be a mobile terminal device, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal device, for example, 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 Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDA), personal computers, tablet computers, Machine-type Communication (MTC) terminal devices, etc. Wireless terminal devices may also be referred to as systems, subscriber units, subscriber stations, mobile stations, mobile stations, remote stations, access points, remote terminal devices, access terminals, user terminals, user agents, user devices, and wireless access points and routers / modems that meet the limitations of this definition, etc., which are not limited in the embodiments of the present application.

[0065] The network device involved in the embodiment of the present application may be a base station, which may include multiple cells providing services to the terminal. Depending on the specific application scenario, the base station may also be called an access point, or may be a device in the access network that communicates with the wireless terminal device through one or more sectors on the air interface, or other names. The network device may be used to replace the received air frame with the Internet Protocol (IP) packet, 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 the attribute management of the air interface. For example, the network device involved in the embodiment of the present application may be an evolutionary network device (evolutional Node B, eNB or e-NodeB) in the long term evolution (LTE) system, a 5G base station (gNB) in the 5G network architecture (next generation system), etc., or a home evolved Node B (HeNB), a relay node, a home base station (femto), a pico base station (pico), a network test device, etc., which is not limited in the embodiment of the present application. In some network structures, the network devices may include centralized unit (CU) nodes and distributed unit (DU) nodes, and the centralized unit and the distributed unit may also be arranged geographically separately.

[0066] The terminal in the embodiment of the present application sends relevant information or similar descriptions to the network device, which only indicates that the terminal sends the relevant information in the form of a wireless signal, and its intended recipient is the network device. The network device can obtain the relevant information by receiving the wireless signal.

[0067] In an exemplary embodiment, Figure 2 As shown, a resource scheduling method is provided, and the method is applied to a base station as an example for explanation. Figure 2 As shown, the resource scheduling method may include:

[0068] Step S201: divide beams into groups based on beams configured by the wireless system.

[0069] Among them, the beam can be a wide beam, or a narrow beam, or other types of beams. The technology for forming the beam can be beamforming technology or other technologies. For example, the beamforming technology can specifically be digital beamforming technology, analog beamforming technology, or hybrid digital / analog beamforming technology. Different beams can be considered as different resources. The beam used to send a signal can be called a transmit beam; the beam used to receive a signal can be called a receive beam. The transmit beam can refer to the distribution of signal strength in different directions in space after the signal is transmitted by the antenna, and the receive beam can refer to the signal strength distribution of the wireless signal received from the antenna in different directions in space.

[0070] The base station can support the use of two or more beams to send and receive data at any time. The terminal can determine the available beams by searching for reference information (such as pilot signals) sent by the base station and feedback the selection result to the base station. Since the area covered by each beam is limited, the base station can use multiple transmit beams to complete the cell coverage and communicate with the terminal.

[0071] In the embodiment of the present application, in order to complete the cell coverage, the wireless system may pre-configure multiple beams. In the embodiment of the present application, there is no restriction on the number of beams pre-configured by the wireless system, the type of beams, and the way of forming beams.

[0072] The base station may divide multiple beam groups based on the beams configured by the wireless system. Each beam group may include a beam configured by the wireless system. Specifically, each beam group may include one or more beams configured by the wireless system. That is, the number of beams included in each beam group may be one or more. The number of beams included in each beam group may be set as needed. It is understood that when the number of beams included in each beam group is small, the number of beam groups is large, and the granularity of resource scheduling is finer; when the number of beams included in each beam group is large, the fewer the number of beam groups, the coarser the granularity of resource scheduling. In addition, the number of beams included in different beam groups may be the same or different. For example, beam group 1 and beam group 2 may both include two beams, or beam group 1 includes one beam but beam group 2 includes two beams. In the embodiment of the present application, there is no restriction on the number of beams included in each beam group, and each beam configured by the wireless system is divided into a beam group, that is, each beam corresponds to a unique beam group.

[0073] In one example, each beam group may include one of the beams configured by the wireless system. Figure 3 FIG. 4 shows an exemplary schematic diagram of beam grouping. Figure 3As shown, the wireless system is configured with four beams, namely, beam 1, beam 2, beam 3, and beam 4. The base station can divide each beam configured by the wireless system into a beam group. That is, the base station can divide the beams configured by the wireless system into four beam groups, namely, beam group 1, beam group 2, beam group 3, and beam group 4. Among them, beam group 1 includes beam 1, beam group 2 includes beam 2, beam group 3 includes beam 3, and beam group 4 includes beam 4.

[0074] In another example, each beam group may include multiple beams configured by the wireless system. For example, the wireless system is configured with four beams, namely beam 1, beam 2, beam 3 and beam 4. The base station may divide beam 1 and beam 2 into beam group 1, and divide beam 3 and beam 4 into beam group 2.

[0075] Step S202: Allocate time-frequency resources of the wireless system to each beam group.

[0076] The base station can allocate the time-frequency resources of the wireless system to each beam group for use, so that each beam group has corresponding time-frequency resources.

[0077] In a possible implementation manner, step S202 may include: allocating the time-frequency resources of the wireless system to each beam group in an equal-proportional manner or a non-equal-proportional manner.

[0078] In one example, the base station can allocate the time-frequency resources of the wireless system to each beam group according to an average allocation strategy, that is, an equal proportion. The total time-frequency resources of the entire wireless system are 100%. Figure 3 As for the division method shown, if the allocation is in equal proportion, the time-frequency resources that each beam group can obtain account for 25% of the total time-frequency resources of the wireless system.

[0079] In another example, the base station may allocate the time-frequency resources of the wireless system in a non-uniformly proportional manner according to the actual population density, the actual traffic model within the coverage area, etc., so that the time-frequency resources allocated to each beam group are related to the actual population density, the actual traffic model within the coverage area, etc. For example, if the actual population density within the coverage area corresponding to a beam group is relatively large, a higher proportion of time-frequency resources is allocated to the beam group; if the actual population density within the coverage area corresponding to a beam group is relatively small, a lower proportion of time-frequency resources is allocated to the beam group.

[0080] Step S203: determining the beam group corresponding to each terminal according to the belonging beam of each terminal accessing the wireless system.

[0081] The terminal's belonging beam may represent the beam to which the terminal belongs among the beams configured by the wireless system. The terminal's belonging beam is determined based on the signal strength of each beam configured by the wireless system. The signal strength of each beam is measured by the terminal at the same time. That is, the terminal can measure the signal strength of each beam configured by the wireless system at the same time, and then determine the terminal's belonging beam based on the measured signal strength.

[0082] In one example, the terminal's home beam may represent the beam with the largest signal strength among the beams. That is, the terminal may determine the beam corresponding to the largest signal strength among the measured signal strengths as the terminal's home beam.

[0083] The base station may first determine the beam group to which the terminal belongs, and then determine the beam group as the beam group corresponding to the terminal. Ultimately, each terminal accessing the base station may determine its corresponding beam group.

[0084] In a possible implementation, step S203 may include: for each terminal accessing the wireless system, receiving a home beam indication sent by the terminal, and grouping the beam to which the home beam of the terminal belongs as the beam group corresponding to the terminal.

[0085] The home beam indication sent by the terminal can be used to indicate the home beam of the terminal. In this way, after receiving the home beam indication sent by the terminal, the base station can determine the beam group corresponding to the terminal according to the beam group where the home beam indicated by the home beam belongs.

[0086] In one example, the attribution beam indication may be sent by the terminal at a certain time interval. In this way, the base station can periodically update the correspondence between the terminal and the beam grouping, which has both stability and accuracy. In another example, the attribution beam indication may be sent by the terminal when the attribution beam changes. In this way, once the attribution beam of the terminal changes, the base station can timely update the correspondence between the terminal and the beam grouping, which ensures real-time performance and improves accuracy.

[0087] Figure 4 FIG. 2 is a flow chart showing a process of determining a home beam provided by an embodiment of the present application. Figure 4 As shown, the process of obtaining the home beam indication may include:

[0088] Step S401: The terminal receives a multi-beam signal sent by a base station.

[0089] Step S402: The terminal measures the signal strength of each beam.

[0090] Step S403: The terminal determines the maximum value of the signal strengths of the various beams and obtains an indication of the belonging beam.

[0091] Step S404: The terminal sends a home beam indication to the base station. After step S404, the process returns to step S401.

[0092] First, the terminal receives the multi-beam signal sent by the base station according to the configuration of the wireless system. Then, the terminal measures the signal strength of each beam, and according to the measured signal strength, determines the beam with the strongest signal strength in the multi-beam signal as the belonging beam. Then, the belonging beam indication is generated according to the belonging beam. Finally, the belonging beam indication is sent to the terminal. After executing the above steps, the terminal can return to step S401 to perform the next round of signal reception, strength measurement and belonging beam transmission.

[0093] like Figure 3 As shown, the signal strengths of the four beams currently measured by the terminal are "beam 1 signal strength", "beam 2 signal strength", "beam 3 signal strength" and "beam 4 signal strength" respectively. When the "beam 1 signal strength" is the maximum, the terminal sends an belonging beam indication to the base station to indicate that "beam 1" is the belonging beam. When the "beam 2 signal strength" is the maximum, the terminal sends an belonging beam indication to the base station to indicate that "beam 2" is the belonging beam. When the "beam 3 signal strength" is the maximum, the terminal sends an belonging beam indication to the base station to indicate that "beam 3" is the belonging beam. When the "beam 4 signal strength" is the maximum, the terminal sends an belonging beam indication to the base station to indicate that "beam 4" is the belonging beam.

[0094] Step S204: performing time-frequency resource scheduling for each terminal based on the beam group corresponding to each terminal and the time-frequency resources allocated to each beam group.

[0095] The base station can obtain the terminal corresponding to each beam group according to the beam group corresponding to each terminal. For example, terminal 1 corresponds to beam group 1, terminal 2 corresponds to beam group 2, terminal 3 corresponds to beam group 1, and terminal 4 corresponds to beam group 2. Then it can be obtained that beam group 1 corresponds to terminal 1 and terminal 3, and beam group 2 corresponds to terminal 2 and terminal 4.

[0096] At this point, the base station has determined the terminal corresponding to each beam group and the time-frequency resources allocated to each beam group. Based on this, for each beam group, the base station can allocate the time-frequency resources allocated by the beam group to the terminal corresponding to the beam group. For example, beam group 1 corresponds to terminal 1 and terminal 2, and beam group 2 corresponds to terminal 3, terminal 4, and terminal 5; beam group 1 is allocated with time-frequency resource 1, and beam group 2 is allocated with time-frequency resource 2; then the base station can allocate time-frequency resource 1 to terminal 1 and terminal 2 in a certain way, and allocate time-frequency resource 2 to terminal 3, terminal 4, and terminal 5 in a certain way.

[0097] In one possible implementation, step S204 may include: determining the priority of each terminal based on the channel state measurement value and service throughput of each terminal; and scheduling time-frequency resources for each terminal based on the beam grouping corresponding to each terminal and the time-frequency resources allocated to each beam grouping in order of priority from high to low.

[0098] The base station can obtain the channel state measurement value and service throughput of each terminal, and then determine the priority of each terminal according to the channel state measurement value and service throughput of each terminal, so as to sort each terminal in order of priority from high to low. It is understandable that the larger the channel state measurement value, the higher the priority of the terminal, and the larger the service throughput, the higher the priority of the terminal. The base station can perform calculation processing on the channel state measurement value and service throughput by rating, weighted summation or other methods to determine the priority of the terminal. The embodiment of the present application does not limit the specific calculation processing method.

[0099] Since different beam groups correspond to different terminals. Therefore, in the embodiment of the present application, the terminals corresponding to the same beam group can be prioritized based on the beam group, and there is no need to prioritize the terminals corresponding to different beam groups. For example, beam group 1 corresponds to terminal 1 and terminal 2, and beam group 2 corresponds to terminal 3, terminal 4, and terminal 5; then terminal 1 and terminal 2 can be prioritized, as well as terminal 3, terminal 4, and terminal 5, and terminal 1 does not need to compare and prioritize with terminal 3, terminal 4, and terminal 5.

[0100] After the base station completes the terminal priority sorting, it can schedule time-frequency resources for each terminal in order of priority from high to low, based on the beam grouping corresponding to each terminal and the time-frequency resources allocated to each beam grouping. Specifically, for each beam grouping, the terminal can prioritize the terminals corresponding to the beam grouping, and then allocate the time-frequency resources corresponding to the beam grouping to the terminals corresponding to the beam grouping in order of priority from high to low. For example, beam grouping 1 corresponds to terminal 1 and terminal 2 and time-frequency resource 1, and the priority of terminal 2 is higher than that of terminal 1. The base station can allocate time-frequency resource 1 to terminal 2 and terminal 1 in turn.

[0101] In a possible implementation, the time-frequency resource scheduling of terminals corresponding to different beam groups is performed in parallel. In this way, the resource scheduling efficiency can be improved. Since the terminals corresponding to different beam groups are allocated with the time-frequency resources of different beam groups, the time-frequency resource scheduling of terminals corresponding to different beam distributions will not affect each other. Therefore, the time-frequency resource scheduling of terminals corresponding to different beam groups can be performed in parallel, thereby improving the efficiency of resource scheduling processing.

[0102] Figure 5 FIG. 1 is a flow chart showing a resource scheduling method provided in an embodiment of the present application. Figure 5 As shown, the method may include:

[0103] Step S500: The base station enters the resource scheduling entry.

[0104] Step S501: The base station divides beams into groups according to beams configured in the wireless system.

[0105] Step S502: The base station allocates time-frequency resources of the wireless system to each beam group.

[0106] Step S503: The base station receives a belonging beam indication from the terminal, and sets or updates a beam group corresponding to the terminal according to the belonging beam indication.

[0107] Step S504: The base station enters each beam group according to the beam grouping and performs resource scheduling processing.

[0108] like Figure 5 As shown, step S504 may include: step S5041 to step S5048.

[0109] Step S5041, priority queuing of terminals within beam 1 group.

[0110] Step S5042: allocating time-frequency resources within beam 1 group.

[0111] Step S5043, priority queuing of terminals within beam 2 group.

[0112] Step S5044: allocating time-frequency resources within beam 2 group.

[0113] Step S5045, priority queuing of terminals within beam 3 group.

[0114] Step S5046, time-frequency resource allocation within beam 3 grouping.

[0115] Step S5057, priority queuing of terminals within beam 4 group.

[0116] Step S5058: allocating time-frequency resources within beam 4 grouping.

[0117] Step S505, end the current resource scheduling. After step S505, return to step S503.

[0118] The base station divides the beam groups according to the configured multiple beams. The base station uses an equal or non-equal proportion allocation method to allocate the total time-frequency resources of the base station system to the beam groups obtained from step S501. The base station receives the belonging beam indication from the terminal and sets or updates the beam group corresponding to the terminal. The base station simultaneously performs terminal priority queuing and time-frequency resource allocation in each beam group for the time-frequency resources and terminals corresponding to each beam group. For example, beam group 1, beam group 2, beam group 3, and beam group 4 perform resource scheduling processing for the terminals in their beam groups at the same time. End this resource scheduling processing and return to the terminal beam group setting or updating and resource scheduling processing in each beam group.

[0119] The resource scheduling method provided in the embodiment of the present application first divides the beam groups based on the beams configured by the wireless system; then allocates the time-frequency resources of the wireless system to each beam group, and determines the beam groups corresponding to each terminal accessing the wireless system; finally, based on the beam group corresponding to each terminal and the time-frequency resources allocated to each beam group, performs time-frequency resource scheduling for each terminal. In this way, time-frequency resource scheduling is performed separately under each beam group, so that the resource scheduling processing particles are reduced to the range of the beam group, thereby refining the resource scheduling processing granularity.

[0120] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders.
