[0002] Spectrum resources, as a scarce resource, are the basis of radio communication. Insufficient frequency supply will affect the development of various radio services. Currently, in addition to planning higher frequency band resources for International Mobile Telecommunications (IMT), an important direction is to strengthen the efficient use of the already allocated frequencies. Since frequency resources have multi-dimensional attributes such as time and space, strengthening the shared use of frequency resources in dimensions such as time and space has become an important means to solve the contradiction between supply and demand. However, using shared frequency bands will cause mutual interference between channels of different networks, thus affecting the channel quality. Summary of the Invention

[0030] 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 and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application. Without conflict, the embodiments in the present application and the features in the embodiments can be arbitrarily combined with each other.

[0031] It should be noted that although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order from that in the flowchart. The terms "first", "second", etc. in the description, claims and the above-mentioned drawings are used to distinguish similar objects and do not necessarily need to describe a specific order or sequence.

[0032] The methods disclosed in the embodiments of the present application include one or more steps or actions for implementing the methods. The method steps and / or actions may be interchanged with each other without departing from the scope of the claims. In other words, unless a specific order of the steps or actions is specified, the order and / or use of the specific steps and / or actions may be modified without departing from the scope of the claims.

[0033] As used in the embodiments of the present application, the term "determine" encompasses a wide variety of actions. For example, "determine" may include operations, calculations, processing, derivations, research, queries (e.g., querying in a table, a database, or another data structure), judgments, and so on. In addition, "determine" may include receiving (e.g., receiving information), accessing (e.g., accessing data in a memory), and so on. Further, "determine" may include resolving, selecting, picking, establishing, and so on. The term "module" may, for example, mean a unit including one or a combination of two or more of hardware, software, and firmware. The "module" may be used interchangeably with, for example, the terms "unit", "logic", "logic block", "component", or "circuit". The "module" may be the smallest unit integrating component elements or a part thereof. The "module" may be the smallest unit for performing one or more functions or a part thereof. The "module" may be implemented mechanically or electronically. For example, the "module" according to the present application may include at least one of an Application-Specific Integrated Circuit (ASIC) chip, a Field-Programmable Gate Array (FPGA), and a programmable logic device for performing known or yet-to-be-developed operations.

[0034] The technologies described in the embodiments of this application can be used in various wireless communication technologies, such as LTE, CDMA, TDMA, FDMA, OFDMA, SC-FDMA, and other networks. The terms "network" and "system" are often used interchangeably. CDMA networks can implement wireless technologies such as Universal Terrestrial Radio Access (UTRA), CDMA2000, and so on. UTRA includes Wideband CDMA (WCDMA) and other variants of CDMA. CDMA 2000 covers the IS-2000, IS-95, and IS-856 standards. TDMA networks can implement wireless technologies such as Global System for Mobile Communications (GSM). OFDMA networks can implement wireless technologies such as NR (e.g., 5G RAN), Evolved UTRA (E-UTRA), Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDMA, and so on. UTRA and E-UTRA are part of the Universal Mobile Telecommunications System (UMTS). The term "cell" can refer to the coverage area of a Node B (NB) and / or NB subsystem that serves the coverage area. In an NR system, the terms "cell" and next-generation Node B (gNB or gNodeB), NR BS, 5G NB, access point (AP), or transmit-receive point (TRP) can be interchangeable. In some examples, a cell may not necessarily be stationary, and the geographical area of a cell can move according to the location of a mobile BS. The term "user" can represent a person who uses an electronic device or a device that uses an electronic device (e.g., an artificial intelligence electronic device).

[0035] Most of the embodiments in this application operate based on the channel state information of the channel between a Base Station (BS) or g Node B (gNB) and a terminal (User Equipment (UE) or Mobile Station (MS)), so the gNB or UE may need to measure the channel state between the base station and the terminal. The above gNB refers to a downlink transmission / uplink reception device located at a predetermined position, and one gNB performs transmission and reception for multiple cells. In a mobile communication system, multiple gNBs can be geographically dispersed, and each gNB can perform transmission and reception for multiple cells. The transmission time for the downlink and uplink can be divided into several frames, each frame can have a predetermined duration (e.g., 10 ms), and each frame can include a variable number of time slots.

[0036] In the embodiments of this application, Channel State Information (CSI) is the channel state information used by a User Equipment (UE) to feedback the downlink channel quality to a g Node B (gNB), so that the gNB can select a suitable Modulation and Coding Scheme (MCS) for the transmission of downlink data, reduce the Block Error Rate (BLER) of downlink data transmission. It consists of a Channel Quality Indicator (CQI), a Precoding Matrix Indicator (PMI), a CSI-RS Resource Indicator (CRI), an SS / PBCH Block Resource Indicator (SSBRI), a Layer Indicator (LI), a Rank Indicator (RI), and a Layer 1 Reference Signal Received Power (L1-RSRP). The time-frequency domain resources required for its transmission are controlled by the gNB.

[0037] In 5G, the cell primary and secondary synchronization signals (Synchronization Signal, SS) and the Physical Broadcast Channel (PBCH) are coupled to a certain extent and appear in the form of an SS / PBCH resource block, simply referred to as SSB (Synchronization Signal and PBCH Block). The physical layer transmission period of the SSB can be configured through the high-layer parameter ssb-periodicityServingCell, and the value range is {5ms, 10ms, 20ms, 40ms, 80ms, 160ms}. The SSB repetition period is mainly set to match the SSB transmission rate. The larger the period, the less time-domain resources the SSB occupies. Within an SSB transmission period, the shaped narrow beams transmitted by the SSB at different candidate transmission moments are not the same.

[0038] In some systems (e.g., Long Term Evolution (LTE) systems), to indicate the quality of a channel (e.g., the link between a UE and a BS), the UE performs measurements and sends a Channel State Information (CSI) report to the BS. For example, the UE can measure the Channel State Information Reference Signal (CSI-RS) sent by the BS. The CSI report typically includes a Channel Quality Indicator (CQI), a Precoding Matrix Indicator (PMI), and a Rank Indicator (RI). The base station can variably adjust the CSI-RS transmission power for various purposes, such as improving channel estimation accuracy, etc. Even if the base station changes the CSI-RS transmission power, the terminal is able to calculate an accurate CQI and report the calculated CQI to the base station. The CQI can be replaced by the Signal-to-Interference Plus Noise Ratio (SINR).

[0039] In a cellular system, the base station should send a reference signal to the terminal for measuring the downlink channel state. In the LTE system of 3GPP, the terminal measures the channel state between the base station and the terminal by using the Channel State Information Reference Signal (CSI-RS) or the Cell Reference Signal (CRS) sent by the base station. In the case of the LTE system, the terminal feeds back information associated with the downlink channel state to the base station, enabling the base station to use this information for downlink scheduling. That is, the terminal measures the reference signal sent by the base station in the downlink and feeds back the information extracted therefrom to the base station in a form defined by the LTE standard.

[0040] Although terms generally associated with 4G and / or 5G wireless technologies may be used to describe aspects in embodiments of the present application, aspects of the content of the present application can be applied to communication systems based on other generations, such as 2G, 3G, and those after 5G.

[0041] Spectrum resources are one of the most important assets of operators. Operators often operate networks of multiple standards simultaneously. After the deployment of 5G, there will be scenarios where 2G, 3G, 4G, and 5G are operated simultaneously. With the continuous increase in the traffic demand of mobile broadband networks, operators are re-farming their 2G / 3G networks to 4G and from 4G to 5G. In traditional operators' multi-standard networks, each standard needs to fixedly occupy a certain amount of spectrum resources. The spectrum resources required for each standard are related to its maximum service capacity. Although the tidal characteristics of the service loads of different standards are different, since each standard monopolizes the spectrum and the spectrums between different standards cannot be shared in a peak-shifted manner, it leads to serious waste of spectrum resources. Spectrum sharing technology can achieve on-demand and dynamic allocation of spectrum resources in the same frequency band.

[0042] Through spectrum refinement management, spectrum sharing can be achieved in multiple dimensions of frequency domain, time domain, and space domain. For example, one of the important applications of 5G, namely drone networking, can achieve reasonable frequency sharing planning in different altitude airspaces, and perform coordination in the frequency domain and time domain between each air layer based on service load and interference characteristic measurements. Combining with dynamic frequency selection and automatic power control functions, a dynamic sharing method is adopted to significantly improve and optimize the spectrum utilization rate.

[0043] Based on this, the embodiments of the present application provide a resource scheduling method, apparatus, device, terminal device, base station, and storage medium, which can adaptively schedule shared frequency bands and improve the usage efficiency of shared frequency bands while ensuring channel quality.

[0044] Referring to Figure 1 , the embodiments of the present application provide a resource scheduling apparatus 100. The resource scheduling apparatus 100 includes:

[0045] A configuration module 110, configured to configure CSI reports, where the CSI reports include aperiodic CSI reports and periodic CSI reports;

[0046] A measurement module 120, connected to the configuration module 110, configured to measure aperiodic first channel state information in a shared frequency band according to the aperiodic CSI report and obtain first measurement information, and measure periodic second channel state information in a non-shared frequency band according to the periodic CSI report and obtain second measurement information;

[0047] A scheduling module 130, connected to the measurement module 120, configured to process the first measurement information and the second measurement information and obtain scheduling information, and determine whether to schedule the shared frequency band according to the scheduling information.

[0048] In some embodiments, configuring the CSI report includes configuring the CSI-RS parameters of the cell and the CSI measurement parameters of the access network device. The aperiodic CSI report includes aperiodic CSI measurement parameters, and the periodic CSI report includes periodic CSI measurement parameters. Among them, the access network device is used to access the wireless communication network of the cell. The access network device may be a user equipment, an access terminal, a user unit, a user station, a mobile station, a mobile device, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user device. The access network device may also be a wireless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication function, a computing device, or other processing devices connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in the future 5G NR network, or a terminal device in the future evolved Public Land Mobile Network (PLMN), etc.

[0049] In some embodiments, the first measurement information includes a first CQI and a first RI, and the second measurement information includes a second CQI and a second RI. Processing the first measurement information and the second measurement information to obtain scheduling information includes: obtaining a first equivalent SINR according to the first CQI; obtaining a first equivalent transport block size (TBSIZE) according to the first equivalent SINR, the first RI, and the first modulation scheme; obtaining a second equivalent SINR according to the second CQI; obtaining a second equivalent transport block size (TBSIZE) according to the second equivalent SINR, the second RI, and the second modulation scheme; obtaining scheduling information according to the first equivalent TBSIZE and the second equivalent TBSIZE. Among them, the scheduling information refers to the scheduling scheme of the network bandwidth determined according to the interference information of the shared frequency band and the non-shared frequency band. If the interference of the shared frequency band is greater than the interference of the non-shared frequency band, the shared frequency band cannot be used, and the scheduling information is to schedule the network bandwidth of the non-shared frequency band; if the interference of the shared frequency band is not greater than the interference of the non-shared frequency band, the shared frequency band can be used, and the scheduling information is to schedule the entire network bandwidth including the shared frequency band and the non-shared frequency band. The larger the equivalent transport block transmitted on the channel, the smaller the interference of the channel. Characterizing the interference information that is not easy to measure through the easily calculated equivalent transport block size can improve the resource scheduling efficiency and thus improve the spectrum utilization rate.

[0050] In some embodiments, obtaining scheduling information according to a first equivalent TBSIZE and a second equivalent TBSIZE includes: comparing the first equivalent TBSIZE and the second equivalent TBSIZE to obtain a first comparison result; and performing scheduling according to the first comparison result. For example, if the comparison result is that the first equivalent TBSIZE is not less than the second equivalent TBSIZE, the shared frequency band can be scheduled, and the scheduling information is to schedule the entire network bandwidth including the shared frequency band and the non-shared frequency band; if the comparison result is that the first equivalent TBSIZE is less than the second equivalent TBSIZE, the shared frequency band cannot be scheduled, and the scheduling information is to schedule the network bandwidth of the non-shared frequency band.

[0051] In other embodiments, obtaining scheduling information according to a first equivalent TBSIZE and a second equivalent TBSIZE includes: adjusting the second equivalent TBSIZE by an adjustment factor to obtain a third equivalent TBSIZE; comparing the first equivalent TBSIZE and the third equivalent TBSIZE to obtain a second comparison result; and performing scheduling according to the second comparison result. The adjustment factor is a positive real number not greater than 1, and the adjustment factor can be set according to the anti-interference ability of the resource scheduling device. For example, if the comparison result is that the first equivalent TBSIZE is less than the second equivalent TBSIZE, the shared frequency band cannot be scheduled, and the second equivalent TBSIZE is adjusted by the adjustment factor so that the first equivalent TBSIZE is not less than the third equivalent TBSIZE, then the shared frequency band can be scheduled. By adjusting the second equivalent TBSIZE by the adjustment factor, the usage conditions of the shared frequency band can be reduced, and the usage efficiency of the shared frequency band can be improved without affecting the channel transmission quality, thereby improving the spectrum utilization rate.

[0052] In some embodiments, the CSI-RS includes a period and an offset, and the measurement module is further configured to: start a first measurement according to the period, the offset, and the DCI, where the first measurement is an aperiodic first CSI measurement on the shared frequency band; and start a second measurement according to the period and the offset, where the second measurement is a periodic second CSI measurement on the non-shared frequency band. The period refers to the number of time slots included in each frame, and the offset refers to the time slot position in each frame for triggering the CSI measurement, and this time slot position corresponds to the start time slot for triggering the CSI measurement in each frame.

[0053] In some embodiments, starting the first measurement according to a period, an offset, and DCI includes: determining a first start time slot according to the period, the offset, and the DCI, where the first start time slot is used to trigger the first measurement in each frame. The configuration module supports setting the number of frames, from a start frame to an end frame, triggering CSI measurements at one or more time slot positions in each frame until CSI measurements are completed for all frames, indicating that one round of CSI measurements is completed. If a new round of CSI measurements is to be started, the time axis jumps back from the end frame to the start frame to restart the CSI measurements. By setting the start time slot, the start time and end time of the CSI measurements can be controlled, which is beneficial for reasonable scheduling. The first measurement is an aperiodic CSI measurement and is triggered by a beam. Therefore, in addition to configuring the period and the offset, a trigger beam of the DCI needs to be received.

[0054] In some embodiments, starting the second measurement according to a period and an offset includes: determining a second start time slot according to the period and the offset, where the second start time slot is used to trigger the second measurement in each frame. The second measurement is a periodic CSI measurement and can be directly triggered by a CSI report. By configuring the period and the offset in the CSI report and setting the second start time slot according to the period and the offset, the start time and end time of the periodic CSI measurements can be controlled, which is beneficial for reasonable resource scheduling.

[0055] In some embodiments, the first start time slot and the second start time slot are different. The first start time slot is used for aperiodic CSI measurements, and the second start time slot is used for periodic CSI measurements. The start time slots of aperiodic CSI measurements and periodic CSI measurements in each frame cannot conflict with each other. If aperiodic CSI measurements and periodic CSI measurements are started at the same time slot, the signals transmitted on the channel may interfere with each other, resulting in incorrect scheduling information. By setting different first and second start time slots, mutual interference of signals can be avoided, and the reliability of resource scheduling can be improved.

[0056] In some embodiments, the configuration module 110 configures the reporting parameters required for CSI reports (for example, CQI, RI, PMI, CRI, BI, etc.) and can support setting at least one reporting parameter. In other embodiments, the configuration module can also support setting the reporting method (for example, periodic, aperiodic, or semi-permanent reporting, where aperiodic and semi-permanent reporting can be configured as one parameter), codebook configuration information, PMI type (full band or partial band), CSI report type (implicit or explicit), channel quality report type (CQI / RSRP), and resource settings.

[0057] In NR, a UE is configured using CSI report settings. The network can send a CSI report trigger, which indicates to the UE to send a CSI report according to the CSI report settings. The UE is also configured using CSI-RS resource settings. The CSI-RS resource settings provide the UE with the configuration of CSI-RS ports mapped to time and frequency resources (e.g., resource blocks (RBs), resource elements (REs)). The UE can be configured to use CSI-RS resources for channel measurements. The CSI-RS report settings and CSI-RS resource settings are configured via higher layer signaling. The CSI-RS trigger and CSI report trigger can be configured via Downlink Control Information (DCI). The CSI-RS trigger is the signaling used to indicate to the UE that CSI-RS will be transmitted. The transmission of CSI-RS follows the settings indicated by the CSI-RS resource settings.

[0058] In the CSI report of LTE, a base station (e.g., BS or gNB) performs the reference signal configuration and reporting-related configuration of a terminal based on the CSI procedure via higher layer configuration. Therefore, in the case of periodic CSI reporting, reporting is performed at the previously configured reporting time points and resources, and in the case of aperiodic CSI reporting, the configuration information previously configured via a trigger in DCI, which is transmitted by the base station via a downlink control signal, is reported.

[0059] In some embodiments, the periodic CSI reporting of a cell is configured as shown in Table 1. CSI-RS-Resource-Mobility is used to configure the first period and the first offset of CSI-RS. The first period and the first offset of CSI-RS are used to determine the frame time slots for triggering CSI measurements. The first period of CSI-RS refers to the number of time slots included in each frame, and the first offset of CSI-RS refers to the time slot position in each frame for triggering CSI measurements. For example, if the first period of CSI-RS is set to 40 time slots, it means that each frame contains 40 time slots. If the first offset of CSI-RS is set to 23, it means that starting from the first time slot of the first frame, CSI-RS is sent at the 23rd time slot position in each frame to trigger CSI measurements. After 40 time slots in the first frame, it automatically jumps to the first time slot of the second frame, and so on. The number of frames can be set, and the number of frames is used to determine the end frame of a round of CSI measurement reporting. For example, if the number of frames is set to 1024, from the first time slot of the first frame to the 40th time slot of the 1024th frame, after the 40th time slot of the 1024th frame, a round of CSI measurement reporting process ends and returns to the first time slot of the first frame.

[0061]

[0062] In some embodiments, the measurement range of the UE is configured as shown in Table 2. "aperiodic" is used to configure the aperiodic measurement range, and the measurement range can be set to a shared frequency band. For example, in the LTE-TDD mode, the frequency band 2575 MHz - 2615 MHz is a shared frequency band for 5G and 4G, and the aperiodic measurement range can be set to a 40M bandwidth of 2575 MHz - 2615 MHz.

[0063] Table 2

[0064]

[0065] In some embodiments, the measurement range of the UE is configured as shown in Table 3. "periodic" is used to configure the periodic measurement range, and the measurement range can be set to the remaining frequency bands that are not shared. For example, in the LTE-TDD mode, the frequency band 2575 MHz - 2615 MHz is a shared frequency band for 5G and 4G, and the periodic measurement range can be set to a 60M bandwidth of 2615 MHz - 2675 MHz. "reportSlotConfig" is used to configure the second period and the second offset of the CSI report measurement reporting of the UE. The second period and the second offset are used to determine the frame time slots for triggering CSI measurements. The second period refers to the number of time slots included in each frame, and the second offset refers to the position of the time slot for triggering CSI measurements in each frame. For example, setting the second period to 80 time slots means that each frame contains 80 time slots, and setting the second offset to 17 means that starting from the first time slot of the first frame, CSI measurements are triggered at the 17th time slot position in each frame. After 80 time slots in the first frame, it automatically jumps to the first time slot of the second frame.

[0066] Table 3

[0067]

[0068] In some embodiments, the measurement module 120 starts CSI measurement according to the CSI report configured by the configuration module 110. Among them, the CSI measurement includes periodic CSI measurement and aperiodic CSI measurement. The periodic CSI measurement is used to measure unshared frequency bands, and the aperiodic CSI measurement is used to measure shared frequency bands. The start time slots of the periodic CSI measurement and the aperiodic CSI measurement are different from each other. For example, the periodic CSI report of the cell is configured as follows: the first period of the CSI-RS is 40 time slots, and the first offset of the CSI-RS is 23; the periodic measurement range of the UE is configured as: 2615 MHz - 2675 MHz; the aperiodic measurement range of the UE is configured as: 2575 MHz - 2615 MHz; the periodic CSI report of the UE is configured as: the second period of the CSI-RS is 80 time slots, and the second offset of the CSI-RS is 17. The first offset of the CSI-RS is 23, and the corresponding air interface time is the 29th time slot in every 40 time slots of each frame. The second offset of the CSI-RS is 17, and the corresponding air interface time is the 19th time slot in every 80 time slots of each frame. When performing periodic CSI measurement, it is triggered based on the periodic CSI report, and the measurement is started at the 19th time slot in every 80 time slots of each frame. When performing aperiodic CSI measurement, it is triggered by DCI based on the aperiodic CSI report, and the measurement is started at the 29th time slot in every 40 time slots of each frame. If it is synchronized with the periodic CSI measurement, it is equivalent to starting the measurement at the 29th time slot and the 69th time slot in every 80 time slots of each frame.

[0069] In the 5G NR system, the aperiodic CSI measurement is triggered by DCI. The periodic CSI report of the cell is configured as follows: the first period of CSI-RS is 40 time slots, and the first offset of CSI-RS is 23, as shown in Table 4. The SSB (synchronization signal and PBCH block) is configured with 2 beams, namely beam 0 and beam 1. SFN represents the frame sequence number, 2n and 2n + 1 represent half-frames, and the combination of 2n and 2n + 1 forms the complete nth frame, where n is an integer and the value range of n is [0, 1024]. In the nth frame, half-frames 2n and 2n + 1 each contain 20 time slots. At the 23rd time slot position in the nth frame, the corresponding air interface time is the 29th time slot, and beam 0 is sent to trigger the CSI measurement. In the (n + 1)th frame, half-frames 2n + 2 and 2n + 3 each contain 20 time slots. At the 23rd time slot position in the (n + 1)th frame, the corresponding air interface time is the 29th time slot, and beam 1 is sent to trigger the CSI measurement. In the (n + 2)th frame, half-frames 2n + 4 and 2n + 5 each contain 20 time slots. At the 23rd time slot position in the (n + 2)th frame, the corresponding air interface time is the 29th time slot, and beam 0 is sent to trigger the CSI measurement. In the (n + 3)th frame, half-frames 2n + 6 and 2n + 7 each contain 20 time slots.

[0072] In some embodiments, the scheduling module 130 obtains CSI measurement results. The CSI measurement results include CQI and RI. It determines the CQI, and the corresponding SINR can be obtained by looking up a table. It determines the SINR, RI, and modulation mode (e.g., QPSK, 16QAM, 64QAM, etc.), and further the corresponding TBSIZE can be obtained by looking up a table. By comparing the TBSIZE1 of periodic CSI measurements and the TBSIZE2 of aperiodic CSI measurements, the interference information of the shared frequency band can be determined. If the interference of the shared frequency band is large, then the non-shared frequency band is used for data communication; if the interference of the shared frequency band is small, then the shared frequency band is used for data communication. In some embodiments, when comparing the TBSIZE1 of periodic CSI measurements and the TBSIZE2 of aperiodic CSI measurements, if TBSIZE1 is greater than TBSIZE2, then the shared frequency band cannot be used, and only the bandwidth of the non-shared frequency band can be used; if TBSIZE1 is not greater than TBSIZE2, then the full bandwidth including the shared frequency band can be used. In other embodiments, the TBSIZE1 is adjusted using an adjustment factor f to obtain TBSIZE3. The value range of the adjustment factor f is (0, 1]. When comparing TBSIZE3 and TBSIZE2, if TBSIZE3 is greater than TBSIZE2, then the shared frequency band cannot be used, and only the bandwidth of the non-shared frequency band can be used; if TBSIZE3 is not greater than TBSIZE2, then the full bandwidth including the shared frequency band can be used. The TBSIZE of periodic CSI measurements is adjusted using the adjustment factor, and the adjustment factor can be set according to the anti-interference ability of the system. By determining whether the shared frequency band can be used, the channel bandwidth can be scheduled. If the shared frequency band can be used, then the full bandwidth can be scheduled; if the shared frequency band cannot be used, then only the bandwidth of the non-shared frequency band can be scheduled.

[0073] Referring to Figure 2 , the embodiments of the present application provide a resource scheduling method, including the following specific steps:

[0074] S210. Configure the CSI-RS parameters of the cell and the CSI measurement parameters of the access network device. The CSI measurement parameters include aperiodic CSI measurement parameters and periodic CSI measurement parameters;

[0075] S220. Measure the aperiodic first channel state information in the shared frequency band and obtain the first measurement information;

[0076] S230. Measure the periodic second channel state information in the non-shared frequency band and obtain the second measurement information;

[0077] S240. Perform scheduling according to the first measurement information and the second measurement information.

[0078] In some embodiments, in step 210, the CSI-RS parameters of the cell include a period and an offset, the aperiodic CSI measurement parameters include CQI, RI, and modulation mode, and the periodic CSI measurement parameters include CQI and RI. Periodic CSI measurements and aperiodic CSI measurements are respectively initiated in an area with a shared frequency band (for example, an area covered by both 5G base stations and 4G base stations). The aperiodic CSI measurement is used to measure the shared frequency band, and the periodic CSI measurement is used to measure the non-shared frequency band. The start time slots of the periodic CSI measurement and the aperiodic CSI measurement are different from each other. In step S220, the aperiodic CSI measurement is triggered by the beam of DCI. For example, the periodic CSI report of the cell is configured as follows: the first period of CSI-RS is 40 time slots, and the first offset of CSI-RS is 22, as shown in Table 5. The SSB is configured with 4 beams, namely beam 0, beam 1, beam 2, and beam 3. SFN represents the frame sequence number, 2n and 2n + 1 represent half-frames, and 2n and 2n + 1 combined form the complete nth frame, where n is an integer and the value range of n is [0, 1024]. In the nth frame, each of the half-frames 2n and 2n + 1 contains 20 time slots. At the 22nd time slot position in the nth frame, the corresponding air interface time is the 28th time slot, and beam 0 is sent to trigger the CSI measurement. In the (n + 1)th frame, each of the half-frames 2n + 2 and 2n + 3 contains 20 time slots. At the 22nd time slot position in the (n + 1)th frame, the corresponding air interface time is the 28th time slot, and beam 1 is sent to trigger the CSI measurement. In the (n + 2)th frame, each of the half-frames 2n + 4 and 2n + 5 contains 20 time slots. At the 22nd time slot position in the (n + 2)th frame, the corresponding air interface time is the 28th time slot, and beam 2 is sent to trigger the CSI measurement. In the (n + 3)th frame, each of the half-frames 2n + 6 and 2n + 7 contains 20 time slots. At the 22nd time slot position in the (n + 3)th frame, the corresponding air interface time is the 28th time slot, and beam 3 is sent to trigger the CSI measurement.

[0081] Step S230, the periodic CSI measurement is triggered by a periodic CSI report. For example, the periodic CSI report of the cell is configured as follows: the first period of the CSI-RS is 40 time slots, and the first offset of the CSI-RS is 22; the periodic CSI report of the UE is configured as follows: the second period of the CSI-RS is 80 time slots, and the second offset of the CSI-RS is 16. The first offset of the CSI-RS is 22, and the corresponding air interface time is the 28th time slot in every 40 time slots of each frame. The second offset of the CSI-RS is 16, and the corresponding air interface time is the 18th time slot in every 80 time slots of each frame. When performing the periodic CSI measurement, the measurement is started at the 18th time slot in every 80 time slots of each frame.

[0082] Step S240, the interference information of the shared band and the non-shared band can be determined according to the first measurement information and the second measurement information. If the interference of the shared band is greater than that of the non-shared band, the non-shared band is used for data communication; if the interference of the shared band is not greater than that of the non-shared band, the shared band is used for data communication. Determining whether the shared band can be used can schedule the channel bandwidth. If the shared band can be used, the full bandwidth including the shared band and the non-shared band can be scheduled; if the shared band cannot be used, only the bandwidth of the non-shared band can be scheduled.

[0083] In some embodiments, step S240, referring to Figure 3 , includes the following specific steps:

[0084] S310. Extract the first channel quality indication and the first rank indication from the first measurement information;

[0085] S320. Extract the second channel quality indication and the second rank indication from the second measurement information;

[0086] S330. Obtain the first equivalent signal-to-interference-plus-noise ratio according to the first channel quality indication;

[0087] S340. Obtain the second equivalent signal-to-interference-plus-noise ratio according to the second channel quality indication;

[0088] S350. Obtain the first equivalent transport block size according to the first equivalent signal-to-interference-plus-noise ratio, the first rank indication, and the first modulation scheme;

[0089] S360. Obtain the second equivalent transport block size according to the second equivalent signal-to-interference-plus-noise ratio, the second rank indication, and the second modulation scheme;

[0090] S370. Schedule the shared band according to the first equivalent transport block size and the second equivalent transport block size.

[0091] By performing step S220 and step S230, CQI, PMI, CRI, SSBRI, LI, RI, L1-RSRP, etc. can be obtained. According to the CQI, the corresponding equivalent SINR can be obtained by looking up a table. Further, according to the SINR, RI, and modulation mode (e.g., QPSK, 16QAM, 64QAM, etc.), the corresponding equivalent TBSIZE can be obtained by looking up a table. The equivalent TBSIZE can be used to evaluate the channel interference. The greater the channel interference, the worse the channel quality, and the smaller the equivalent TBSIZE of the channel; the smaller the channel interference, the better the channel quality, and the larger the equivalent TBSIZE of the channel. By comparing the TBSIZE1 of the periodic CSI measurement and the TBSIZE2 of the aperiodic CSI measurement, the interference information of the shared frequency band and the non-shared frequency band can be determined. If the interference of the shared frequency band is greater than that of the non-shared frequency band, the non-shared frequency band is used for data communication; if the interference of the shared frequency band is not greater than that of the non-shared frequency band, the shared frequency band is used for data communication.

[0092] In some embodiments, step S370, referring to Figure 4 , includes the following steps:

[0093] S410. Compare the first equivalent transport block size and the second equivalent transport block size;

[0094] S420. Perform scheduling according to the comparison result.

[0095] The equivalent TBSIZE can represent the quality of the channel. By comparing the TBSIZE1 measured by periodic CSI and the TBSIZE2 measured by aperiodic CSI, it is determined whether to use the shared frequency band. For example, by performing step S310 and step S320, the CQI1 = 13 and RI1 = 1 obtained from the periodic CSI measurement, and the CQI2 = 14 and RI2 = 1 obtained from the aperiodic CSI measurement are obtained. Among them, the modulation methods of the periodic CSI measurement and the aperiodic CSI measurement are both 16QAM. By looking up the table, it is obtained that the SINR1 corresponding to CQI1 = 13 is 15 dB, and the SINR2 corresponding to CQI2 = 14 is 17 dB. Further, by looking up the table, the TBSIZE1 corresponding to SINR1 = 15 dB, RI1 = 1, and the modulation method of 16QAM is 65576 bits, and the TBSIZE2 corresponding to SINR2 = 17 dB, RI2 = 1, and the modulation method of 16QAM is 73776 bits. Since TBSIZE1 is less than TBSIZE2, that is, the channel quality of the shared frequency band is better than that of the non-shared frequency band, the shared frequency band can be used for data communication, that is, the full bandwidth including the shared frequency band and the non-shared frequency band can be scheduled. Another example is that by performing step S310 and step S320, the CQI1 = 13 and RI1 = 1 obtained from the periodic CSI measurement, and the CQI2 = 2 and RI2 = 1 obtained from the aperiodic CSI measurement are obtained. Among them, the modulation methods of the periodic CSI measurement and the aperiodic CSI measurement are both 16QAM. By looking up the table, it is obtained that the SINR1 corresponding to CQI1 = 13 is 15 dB, and the SINR2 corresponding to CQI2 = 2 is -2 dB. Further, by looking up the table, the TBSIZE1 corresponding to SINR1 = 15 dB, RI1 = 1, and the modulation method of 16QAM is 65576 bits, and the TBSIZE2 corresponding to SINR2 = -2 dB, RI2 = 1, and the modulation method of 16QAM is 5384 bits. Since TBSIZE1 is greater than TBSIZE2, that is, the channel quality of the non-shared frequency band is better than that of the shared frequency band, the shared frequency band cannot be used for data communication, that is, only the bandwidth of the non-shared frequency band can be scheduled.

[0096] In some other embodiments, step S370, referring to Figure 5 , includes the following steps:

[0097] S510. Adjust the second equivalent transport block size using an adjustment factor to obtain a third equivalent transport block size;

[0098] S520. Compare the first equivalent transport block size and the third equivalent transport block size;

[0099] S530. Perform scheduling according to the comparison result.

[0100] The TBSIZE of the periodic CSI measurement is adjusted using an adjustment factor, which can be set according to the anti-interference ability of the system. The value range of the adjustment factor f is (0, 1]. Within the interference range that the system can tolerate, by adjusting the TBSIZE of the non-shared frequency band, the usage conditions of the shared frequency band can be reduced, and the usage efficiency of the shared frequency band can be improved. For example, by performing step S310 and step S320, the CQI1 = 13 and RI1 = 1 of the periodic CSI measurement are obtained, and the CQI2 = 2 and RI2 = 1 of the aperiodic CSI measurement are obtained. Among them, the modulation methods of the periodic CSI measurement and the aperiodic CSI measurement are both 16QAM. By looking up the table, it is obtained that SINR1 = 15dB corresponding to CQI1 = 13, and SINR2 = -2dB corresponding to CQI2 = 2. Further by looking up the table, it is obtained that TBSIZE1 = 65576 bits corresponding to SINR1 = 15dB, RI1 = 1, and the modulation method of 16QAM, and TBSIZE2 = 5384 bits corresponding to SINR2 = -2dB, RI2 = 1, and the modulation method of 16QAM. Perform step S510, and adjust TBSIZE1 using the adjustment factor f = 0.05 (TBSIZE1 * f) to obtain TBSIZE3 = 3278.8 bits. Since TBSIZE2 is greater than TBSIZE3, that is, the channel quality of the shared frequency band is better than that of the adjusted non-shared frequency band, data communication can be performed using the shared frequency band, that is, the full bandwidth including the shared frequency band and the non-shared frequency band can be scheduled. If TBSIZE1 is not adjusted using the adjustment factor f, since TBSIZE1 is greater than TBSIZE2, that is, the channel quality of the non-shared frequency band is better than that of the shared frequency band, data communication cannot be performed using the shared frequency band, that is, only the bandwidth of the non-shared frequency band can be scheduled. The use of the adjustment factor reduces the usage conditions of the shared frequency band.

[0101] In some embodiments, after step S210 and before step S240, referring to Figure 6 , the CSI-RS includes a period and an offset, and the resource scheduling method further includes the following specific steps:

[0102] S610. Execute step S220 according to the period, offset, and downlink control information;

[0103] S620. Execute step S230 according to the period and offset.

[0104] Both periodic CSI measurements and aperiodic CSI measurements are triggered based on CSI reports. Before starting CSI measurements, CSI reports need to be configured. To configure the periodic CSI report of a cell, the period and offset of the CSI-RS are mainly configured. The period and offset of the CSI-RS are used to determine the frame time slots for triggering CSI measurements. The period of the CSI-RS refers to the number of time slots included in each frame, and the offset of the CSI-RS refers to the time slot position in each frame for triggering CSI measurements. Step S610: Configure the periodic CSI report according to the period and offset. Step S620: Since aperiodic CSI measurements are triggered by the beam trigger of the downlink control information (DCI), the aperiodic CSI report needs to be configured according to the period, offset, and DCI. The CSI-RS of the cell can be configured using CSI-RS-Resource-Mobility as shown in Table 1, the aperiodic CSI report of the UE can be configured using aperiodic as shown in Table 2, and the periodic CSI report of the UE can be configured using periodic as shown in Table 3.

[0105] In some embodiments, step S610, referring to Figure 7 , includes the following steps:

[0106] S710. Determine the first start time slot of the aperiodic CSI measurement according to the period, offset, and downlink control information;

[0107] S720. Execute step S220 at the first start time slot of each frame.

[0108] The period of the CSI-RS can determine the number of time slots included in each frame, and the offset of the CSI-RS can determine the time slot position in each frame for triggering CSI measurements. There is a corresponding relationship between the time slot position for triggering CSI measurements and the start time slot for triggering CSI measurements. For example, an offset of 22 corresponds to a start time slot of the 28th time slot, and an offset of 16 corresponds to a start time slot of the 18th time slot. When configuring the aperiodic CSI report, the first start time slot of the air interface moment is determined according to the period, offset, and DCI, and the aperiodic CSI measurement report is reported by beam trigger at the first start time slot of each frame.

[0109] In some embodiments, step S620, referring to Figure 8 , includes the following steps:

[0110] S810. Determine the second start time slot of the periodic CSI measurement according to the period and offset;

[0111] S820. Execute step S230 at the second start time slot of each frame.

[0112] The period of the CSI-RS can determine the number of time slots included in each frame, and the offset of the CSI-RS can determine the time slot position in each frame that triggers CSI measurement. The time slot position pointed to by the offset is not the starting time slot for triggering CSI measurement, and there is a corresponding relationship between the time slot position for triggering CSI measurement and the starting time slot. For example, an offset of 23 corresponds to a starting time slot of the 29th time slot, and an offset of 17 corresponds to a starting time slot of the 19th time slot. When configuring periodic CSI reporting, the second starting time slot of the air interface moment is determined according to the period and the offset, and a periodic CSI measurement report is reported at the second starting time slot of each frame.

[0113] In some embodiments, the first starting time slot of the aperiodic CSI measurement is different from the second starting time slot of the periodic CSI measurement. The starting time slot of the aperiodic CSI measurement and the starting time slot of the periodic CSI measurement in each frame cannot conflict with each other. By setting different first and second starting time slots to avoid conflicts between the two, crosstalk between signals transmitted on the channel can be avoided, thereby improving the reliability of resource scheduling.
