Technical Field

The present disclosure relates to the field of wireless communication technology, and in particular to a method, device, and computer equipment for adjusting interference in a wireless communication channel.

Background Art

With the development of wireless communication technology, in the next generation of broadband wireless communication networks, solving how to support larger bandwidth in the current wireless communication system bandwidth has become a key factor in improving the user terminal throughput between cells and the average user terminal throughput and faces severe challenges.

At present, the Long Term Evolution (LTE) and LTE-Advanced of the 3rd Generation Partnership Project (3GPP), as well as the latest 5G NR (New Radio), all propose to effectively improve the characteristics such as throughput and peak rate through methods such as UL SU-MIMO, DL MIMO extension, UL/DL Coordinated Multi Point Transmission/Reception, Coordinated Multi Point Transmission/Reception (CoMP), and heterogeneous networks. In order to effectively support these new technologies in wireless communication networks, it is necessary to coordinate different cells and clusters and enhance coverage of wireless communication channels.

However, in traditional technologies, since different operators use different spectra and frequency bands, the signal transmission delay across operators will increase significantly. At the same time, cross-link interference (CLI) between different operators will be introduced. The current collaborative coverage enhancement and uplink throughput enhancement technologies will inevitably introduce various interferences, resulting in reduced throughput.

In order to make the purpose, technical solution and advantages of the present disclosure more clear, the present disclosure is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present disclosure and are not used to limit the present disclosure.

It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of this article described here can be implemented in an order other than those illustrated or described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, device, product or equipment that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment.

In this article, the term "and/or" is only a way to describe the association relationship of associated objects, indicating that there can be three relationships.

In addition, the character "/" in this article generally indicates that the associated objects before and after are in an "or" relationship.

As described in the background technology, currently, wireless communication channels have the following main problems:

1. When control channels, such as Sounding Reference Signal (SRS), are periodically transmitted through high-layer signaling, in order to provide sufficient accuracy for estimating the control channel state information (CSI), SRS is periodically configured according to the Doppler curve. However, considering the tradeoff between control channel overhead and the accuracy of channel state estimation, when multiple users are multiplexed in the same control channel symbol, it is difficult to configure the period of the control channel based on the mobility of the user equipment (UE) and/or gNB (5G Base Station), resulting in reduced throughput.

2. For supporting CoMP features and heterogeneous network deployment, the orthogonality of control channel sequences within the cell cannot guarantee the minimization of cross interference of control channels and provide more reliable channel state estimation.

3. For supporting CoMP features and heterogeneous network deployment, the orthogonality of control channel sequences within the cell cannot guarantee the minimization of cross interference of control channels and provide more reliable channel state estimation.

4. The control channel coverage within the cell cannot guarantee the monitorability of the neighboring cell gNB under the support of CoMP characteristics and heterogeneous networks, as well as the reliable CSI estimation of UEs with CoMP characteristics.

5. The early Rel-15 version of 5G NR of 3GPP 5G adapted to the growing business needs of the downlink (DL) and introduced new features and enhancements. However, with the development of the times, new services and applications with large uplink (UL) payloads have emerged. For example, extended reality (XR) and virtual reality (VR) applications with real-time video feeds from devices are becoming more and more widespread, and uplink (UL) traffic demand has begun to increase significantly. After the 3GPP 5G Rel-18 version, 5G introduced functional enhancements to the uplink (UL), but how to balance the uplink (UL) and downlink (DL) loads will face challenges.

6. In different application scenarios, especially in high-power urban macro environments, coverage under different load conditions, especially coverage of cell-edge users, is unbalanced in uplink (UL) and downlink (DL);

7. Since different operators use different spectra and frequency bands, the signal transmission delay across operators will increase significantly. At the same time, cross-link interference (CLI) between different operators will be introduced. The current collaborative coverage enhancement and uplink throughput enhancement technologies will inevitably introduce new types of interference such as gNB self-interference (SI) and gNB-to-gNB cross-link interference (CLI), resulting in a significant decrease in collaborative coverage performance and a significant decrease in uplink (UL) throughput, especially for cell-edge users.

Based on the above main problems existing in the wireless communication channel, an embodiment of the present disclosure provides an interference adjustment method for a wireless communication channel, which is intended to at least partially solve the above problems.

The embodiment of the present disclosure provides an interference adjustment method for a wireless communication channel, which can be applied in an application environment as shown in FIG. 1. The base station 102 communicates with multiple user terminals 104 through a wireless communication channel. The base station 102 and the multiple user terminals 104 can constitute a wireless communication system. The base station 102 obtains the interference type of interference generated by the wireless communication system, and obtains the real-time throughput of the wireless communication system. The base station 102 determines the actual load of the wireless communication system. The base station 102 selects at least one matching adjustment method to adjust the wireless communication channel of the wireless communication system based on the interference type of the interference, the real-time throughput and the actual load. The adjustment method includes: adjusting the duplex mode of the wireless communication channel and adjusting the wireless resources of the wireless communication channel. The user terminal 104 can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, Internet of Things devices and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart car-mounted devices, etc. The base station 102 can usually be a gNB (5G Base Station), which refers to a base station in the fifth generation mobile communication technology. It is a key component in the 5G network and is used to provide wireless network coverage and connect devices. gNB uses new wireless technology and spectrum resources to support higher data transmission rates, lower latency and more connected devices. It can cover a wider area and support more user equipment access, and is an important device for achieving 5G network coverage and transmission.

In one embodiment, as shown in FIG. 2 , a method for adjusting interference of a wireless communication channel is provided, and the method is described by taking the base station 102 of the wireless communication system in FIG. 1 as an example, including the following steps:

S202: Obtain an interference type of interference generated by the wireless communication system, and obtain a real-time throughput in the wireless communication system.

Among them, interference refers to electromagnetic wave interference from other wireless devices or signals, which may affect the communication quality and speed between devices. For example, the interference generated by gNB and user terminal (UE) in random access to wireless communication system, cell switching, CoMP, heterogeneous network or other scenarios. The interference type in some embodiments of the present disclosure may include various types of interference generated within/between cells, cell edges, etc. Further, it may include: inter-subband cross-link interference (CLI) between gNB and gNB, inter-subband cross-link interference (CLI) between user terminals (UE) within a cell, inter-subband cross-link interference (CLI) between user terminals (UE) between cells, interference between user terminals (UE) of other adjacent cells to gNB, interference between gNB of adjacent cells to user terminals (UE), etc.

Specifically, after accessing the wireless communication system, the base station can obtain the interference type of interference generated by various devices (including user terminals and base stations) in the wireless communication. The base station can also obtain the real-time throughput of the wireless communication system.

In some exemplary embodiments, the user terminal (UE) can actively measure its own various interference levels and interference strengths and feed them back to the gNB. The gNB determines the interference type of the interference generated by the wireless communication system based on the information measured by the user terminal (UE) and other information obtained by itself in the wireless communication system. The gNB can also select the modulation and coding scheme (MCS) through the channel quality indication (CQI, Channel Quality Information), perform periodic/non-periodic (burst)/dynamic link adaptation for all user terminals (UE) in the cell of the wireless communication system, and finally make all user terminals (UE) reach the maximum link rate that can be supported without exceeding the target block error rate (BLER, BLock Error Rate), thereby determining the real-time throughput in the wireless communication system.

S204: Determine an actual load of the wireless communication system.

The actual load may include heavy load, medium load and light load.

Specifically, the base station may also determine the actual load of the wireless communication system.

In some exemplary embodiments, the actual load of the wireless communication system may be determined based on the number of devices connected in the wireless communication system, bandwidth utilization, etc.

S206, based on the interference type of the interference, the real-time throughput and the actual load, select at least one matching adjustment method to adjust the wireless communication channel of the wireless communication system; wherein the adjustment method includes: adjusting the duplex mode of the wireless communication channel and adjusting the wireless resources of the wireless communication channel.

The duplex mode may include simplex and full duplex. Adjusting the duplex mode of the wireless communication channel may include adjusting the duplex mode to simplex or full duplex. Adjusting the wireless resources of the wireless communication channel may include releasing the wireless resources of the wireless communication channel or adjusting the number of wireless resources of the wireless communication channel.

Specifically, after determining the interference type of the interference, an adjustment method matching the above information can be selected to adjust the wireless communication channel according to the interference type, real-time throughput and actual load, so as to reduce the interference of the wireless communication channel and thus improve the throughput.

In the above-mentioned interference adjustment method for the wireless communication channel, by obtaining the interference type, real-time throughput and actual load of the interference, the state of the current wireless communication system can be determined according to the interference type, real-time throughput and actual load, so as to select a matching adjustment method in a targeted manner, adjust the duplex mode of the wireless communication channel to balance the throughput of the wireless communication channel, and also adjust the wireless resources to cope with the wireless resource requirements brought about by the increase/decrease of various business requirements; cope with the redundancy of resource allocation in the overlapping and/or non-overlapping areas of the wireless resource allocation of the wireless communication channel caused by various interferences, and cope with the insufficient allocation of wireless resources when dealing with various interferences, thereby improving the throughput of the wireless communication system.

In one embodiment, as shown in FIG3 , the real-time throughput in the wireless communication system includes: the real-time throughput of the uplink and the real-time throughput of the downlink; the selecting at least one matching adjustment mode to adjust the wireless communication channel of the wireless communication system based on the interference type, the real-time throughput and the actual load includes:

S302: Determine a throughput type based on the real-time throughput of the uplink, the real-time throughput of the downlink, and the actual load.

Among them, the uplink (UL) in the wireless communication channel refers to the communication path for transmitting data from the user equipment (such as a mobile phone) to the base station (such as a mobile phone tower). In the uplink, the user equipment sends data, voice, images and other information to the base station. The downlink (DL) refers to the communication path for transmitting data from the base station to the user equipment. In the downlink, the base station sends data, voice, images and other information to the user equipment. The throughput type can be the state of the current wireless communication system determined by the actual load and the real-time throughput of the uplink and the real-time throughput of the downlink.

Specifically, the base station may determine the state of the current wireless communication, that is, the throughput type, based on the real-time throughput of the uplink, the real-time throughput of the downlink, and the actual load.

S304: Based on the throughput type and the interference type of the interference, select at least one matching adjustment method to adjust the wireless communication channel of the wireless communication system.

Specifically, after the throughput type is determined, at least one adjustment method matching the throughput type and the interference type can be determined based on the throughput type and the interference type, and the wireless communication channel of the wireless communication system can be adjusted using the at least one matching adjustment method.

In this embodiment, by determining the throughput type, the current state of the wireless communication system can be accurately obtained, so that adjustments can be made accurately to improve the throughput of the wireless communication system.

In one embodiment, the adjusting the duplex mode of the wireless communication channel and adjusting the wireless resources of the wireless communication channel include:

Adjust the allocation position of the sub-band resources of the wireless communication channel, adjust the duplex mode of the uplink wireless resources, adjust the duplex mode of the downlink wireless resources, adjust the number of uplink wireless resources, adjust the number of downlink wireless resources, release the uplink wireless resources, and release the downlink wireless resources.

Among them, adjusting the allocation position of the wireless communication channel subband resources refers to reallocating the position of the subband in the existing wireless communication channel resources. A subband refers to a small interval of the channel spectrum used to transmit data. Adjusting the allocation position of the subband can change the spectrum interval between different subbands, thereby optimizing the utilization efficiency of channel resources. By reallocating the position of the subband, spectrum resources can be more reasonably allocated to different users or applications, thereby improving the utilization efficiency of the spectrum; adjusting the allocation position of the subband can isolate the spectrum resources between different users or applications from each other, thereby reducing interference between them.

Adjust the duplex mode of the uplink wireless resources, which include simplex and full-duplex. By adjusting the duplex mode of the uplink wireless resources to simplex or full-duplex, the size of the uplink (UL) resources can be adjusted when the uplink (UL) wireless resources are relatively sufficient, and the throughput of the uplink (UL) and downlink (DL) can be balanced by adjusting the uplink (UL) resources, thereby enhancing the collaborative coverage.

Adjust the duplex mode of the downlink wireless resources, which also includes simplex and full-duplex. By adjusting the duplex mode of the downlink wireless resources to simplex or full-duplex, when the downlink (DL) wireless resources are relatively sufficient, adjust the size of the downlink (DL) resources, balance the throughput of the uplink (UL) and downlink (DL) through the adjustment of the downlink (DL) resources, and thus enhance the collaborative coverage.

Adjust the number of uplink wireless resources, including: increase/decrease the number of uplink (UL) wireless resources. Purpose: To cope with the uplink (UL) wireless resource demand caused by the increase/decrease of uplink (UL) business demand; to cope with the redundancy of resource allocation in overlapping and/or non-overlapping areas of uplink (UL) wireless resource allocation caused by various interferences; to cope with insufficient downlink (DL) resource allocation caused by various interferences; to cope with the full link resource allocation caused by various interferences, when it still cannot effectively reduce the interference, provide a protection band on the wireless resources to isolate the resource allocation in overlapping and/or non-overlapping areas.

Adjust the number of downlink wireless resources, including: increase/decrease the number of downlink (DL) wireless resources. Purpose: To cope with the downlink (DL) wireless resource demand caused by the increase/decrease of uplink and downlink (DL) business demand; to cope with the redundancy of resource allocation in overlapping and/or non-overlapping areas of downlink (DL) wireless resource allocation caused by various interferences; to cope with insufficient uplink (UL) resource allocation caused by various interferences; to cope with the full link resource allocation caused by various interferences, when it still cannot effectively reduce the interference, provide a protection band on the wireless resources to isolate the resource allocation in overlapping and/or non-overlapping areas.

Normally, before adjusting the uplink (UL)/downlink (DL) wireless resource size, the duplex mode must be adjusted first. When adjusting the uplink (UL) and/or downlink (DL) wireless resource duplex mode still does not meet the wireless resource allocation requirements, the uplink (UL) wireless resource size is adjusted to cooperate with the adjustment of the wireless resource duplex mode to meet the uplink (UL) and/or downlink (DL) wireless resource requirements.

Release uplink (UL) and/or downlink (DL) wireless resources, including: temporarily not allowing new user terminals (UE) to access the 5G wireless communication system, offline user terminals (UE) with large interference at the cell edge that have already accessed the 5G wireless communication system, user terminals (UE) with poor adjacent channel selectivity (ACS, Adjacent Channel Selectivity), i.e., user terminals (UE) in cells and/or between cells with strong interference, and user terminals (UE) in cells and/or between cells with low self-interference ratio (RSI, Ratio of Self-Interference). Purpose: To solve various interferences caused by asymmetric allocation of uplink (UL) and/or downlink (DL) wireless resources under heavy load, and the lack of protection band when allocating wireless resources in overlapping/non-overlapping areas; to solve the imbalanced allocation of wireless resources when the throughput of uplink (UL) and/or downlink (DL) increases and/or decreases due to service changes.

In one embodiment, when the actual load is a heavy load, the real-time throughput includes: high throughput and low throughput, and determining the throughput type based on the real-time throughput of the uplink, the real-time throughput of the downlink and the actual load includes:

In response to the uplink being high throughput and the downlink being high throughput, determining the throughput type to be heavy-load high full link throughput;

In response to the uplink being of high throughput and the downlink being of low throughput, determining the throughput type to be heavy-load high uplink throughput;

In response to the uplink having a low throughput and the downlink having a high throughput, determining the throughput type as heavy-load high downlink throughput;

In response to the uplink having a low throughput and the downlink having a low throughput, the throughput type is determined to be a heavy-load low full-link throughput.

Specifically, the actual load and real-time throughput of the uplink (UL) and the downlink (DL) can obtain the first relationship shown in Table 1.

Table 1

In one embodiment, when the interference type is inter-base station sub-band cross-link interference, inter-base station sub-band cross-link interference refers to interference of a gNB receiver from another gNB transmitter. As shown in FIG4 , the interference between gNB1 and gNB3, and between gNB2 and gNB3 can be inter-base station sub-band cross-link interference.

The selecting at least one matching adjustment mode to adjust the wireless communication channel of the wireless communication system based on the throughput type and the interference type of the interference includes:

In response to the throughput type being heavy-load high full-link throughput, the wireless communication channel is adjusted in at least one of the following ways: adjusting the allocation position of the sub-band resources of the wireless communication channel, releasing the wireless resources of the uplink, and releasing the wireless resources of the downlink.

Specifically, when the interference type is cross-link interference between sub-bands between base stations, and the throughput type is heavy-load high full-link throughput, any of the following methods can be selected for adjustment, adjusting the allocation position of the sub-band resources of the wireless communication channel, releasing the wireless resources of the uplink, and releasing the wireless resources of the downlink. The channel duplex mode is not adjusted, thereby releasing wireless resources and increasing the protection band as much as possible on the limited wireless resources to reduce interference.

In response to the throughput type being heavy-load high uplink throughput, the wireless communication channel is adjusted in at least one of the following ways: adjusting the duplex mode of downlink wireless resources, adjusting the number of downlink wireless resources.

Specifically, when the interference type of the interference is inter-subband cross-link interference between base stations, and the throughput type is heavy-load high uplink throughput, any of the following methods can be selected for adjustment, adjusting the duplex mode of the downlink wireless resources, adjusting the number of downlink wireless resources, and thus adjusting the duplex mode of the downlink (DL) to increase the uplink (UL) transmission. Match the downlink (DL) channel resources as much as possible on the asymmetric uplink (UL) to increase the full-duplex channel subband. Add a guard band to the overlapping channel subband to reduce interference. Among them, asymmetry means that the actual allocation value of the wireless resources on the uplink (UL) and/or downlink (DL) is asymmetric. For example, the uplink (UL) requires 9 subcarriers of wireless resource allocation, and the downlink (DL) requires 19 subcarriers of wireless resource allocation, then it can be determined that the uplink and downlink are asymmetric. Symmetry means that the uplink (UL) and downlink (DL) wireless resources are evenly allocated.

In response to the throughput type being heavy-load high downlink throughput, the wireless communication channel is adjusted in at least one of the following ways: adjusting the duplex mode of uplink wireless resources, adjusting the number of uplink wireless resources.

Specifically, the duplex mode of the uplink wireless resources and the number of uplink wireless resources are adjusted, thereby adjusting the duplex mode of the uplink (UL) to increase downlink (DL) transmission, and matching the uplink (UL) channel resources as much as possible on the asymmetric downlink (DL) to increase the full-duplex channel subbands. Guard bands can also be added to overlapping channel subbands to reduce interference.

In response to the throughput type being heavy-load low full-link throughput, the wireless communication channel is adjusted in at least one of the following ways: adjusting the allocation position of the sub-band resources of the wireless communication channel, adjusting the duplex mode of the uplink wireless resources, adjusting the duplex mode of the downlink wireless resources, adjusting the number of uplink wireless resources, and adjusting the number of downlink wireless resources.

Specifically, the allocation position of the wireless communication channel sub-band resources is adjusted, the duplex mode of the uplink wireless resources is adjusted, the duplex mode of the downlink wireless resources is adjusted, the number of uplink wireless resources is adjusted, and the number of downlink wireless resources is adjusted. This adjustment method does not require adjustment in the case of low interference to reduce signaling interaction overhead, and can also adjust the duplex mode of the uplink (UL) and/or downlink (DL) on the symmetric channel sub-band to full duplex as much as possible to increase the transmission of the full link at the same time under interference-limited conditions, thereby increasing the throughput of the 5G wireless communication system.

In one embodiment, when the interference type of the interference is the first inter-subband cross-link interference between user terminals. The first inter-subband cross-link interference refers to the impact of the user terminal (UE) transmission on non-overlapping resources in the same cell on another user terminal (UE), and the non-overlapping resources refer to not using the same resources in the time domain, frequency domain and/or code domain. As shown in Figure 5, the interference between the user terminal UE4 and the user terminal UE1 can be the first inter-subband cross-link interference.

The selecting at least one matching adjustment mode to adjust the wireless communication channel of the wireless communication system based on the throughput type and the interference type of the interference includes:

In response to the throughput type being heavy-load high full-link throughput, the wireless communication channel is adjusted in at least one of the following ways: adjusting the allocation position of the sub-band resources of the wireless communication channel, releasing the wireless resources of the uplink, and releasing the wireless resources of the downlink.

Specifically, the allocation position of the wireless communication channel sub-band resources can be adjusted, at least one of the uplink wireless resources and the downlink wireless resources can be released, so as to adjust the allocation position of the existing channel sub-band resources to reduce interference between user terminals (UEs); some resources can also be released to increase the protection band to reduce interference as much as possible.

In response to the throughput type being heavy-load high uplink throughput, the wireless communication channel is adjusted in at least one of the following ways: adjusting the allocation position of the subband resources of the wireless communication channel, and adjusting the number of uplink wireless resources.

Specifically, the allocation position of the wireless communication channel sub-band resources can be adjusted to reduce interference between user terminals (UEs), and the size of the uplink (UL) channel sub-band resources can be adjusted to increase the guard band to reduce interference. The guard band refers to an idle frequency band set up in wireless communication to ensure normal signal transmission. In the electromagnetic spectrum, different wireless communication systems or services may use different frequency bands for communication. In order to avoid interference and conflict between different systems, it is necessary to set a certain guard band between them. The guard band generally refers to a blank frequency band set between two adjacent frequency bands of the spectrum, which is used to avoid the influence of signal interference of adjacent frequency bands on other frequency bands. The setting of this guard band can reduce the mutual interference between different signals in the spectrum and ensure the stable operation between communication systems.

In response to the throughput type being heavy-load high downlink throughput, the wireless communication channel is adjusted in at least one of the following ways: adjusting the allocation position of the subband resources of the wireless communication channel, and adjusting the number of downlink wireless resources.

Specifically, the allocation position of wireless communication channel sub-band resources can be adjusted to reduce interference between user terminals (UEs), and the size of downlink (DL) channel sub-band resources can be adjusted to increase the guard band to reduce interference.

In response to the throughput type being heavy-load low full-link throughput, the wireless communication channel is adjusted in at least one of the following ways: adjusting the allocation position of the sub-band resources of the wireless communication channel, adjusting the duplex mode of the uplink wireless resources, adjusting the duplex mode of the downlink wireless resources, adjusting the number of uplink wireless resources, and adjusting the number of downlink wireless resources.

Specifically, the allocation position of the wireless communication channel sub-band resources can be adjusted to reduce interference between user terminals (UEs), the duplex mode of the channel sub-band resources of the uplink (UL) and/or downlink (DL) can be adjusted to increase the throughput on the symmetrical channel sub-band resources, and the size of the channel sub-band resources of the uplink (UL) and/or downlink (DL) can be adjusted simultaneously to increase the protection band to reduce interference.

In one embodiment, when the interference type of the interference is the second inter-subband cross-link interference between user terminals. The second inter-subband cross-link interference refers to the impact of the user terminal (UE) transmission on non-overlapping resources in an adjacent cell on another user terminal (UE). As shown in Figure 6, the interference between the user terminal UE3 and the user terminal UE1, and the interference between the user terminal UE3 and the user terminal UE2 can be the second inter-subband cross-link interference.

The selecting at least one matching adjustment mode to adjust the wireless communication channel of the wireless communication system based on the throughput type and the interference type of the interference includes:

In response to the throughput type being heavy-load high full-link throughput, the wireless communication channel is adjusted in at least one of the following ways: adjusting the allocation position of the sub-band resources of the wireless communication channel, releasing the wireless resources of the uplink, and releasing the wireless resources of the downlink.

Specifically, by adjusting the allocation position of the wireless communication channel subband resources, the gNB of the adjacent cell can adjust the position of the allocated channel subband resources at the same time through inter-cell collaboration to reduce the interference of the user terminal (UE) between the cells as much as possible. Releasing the uplink wireless resources and releasing the downlink wireless resources can enable the gNB of the adjacent cell to release the user terminal (UE) carried on the overlapping channel subband resources with high interference through inter-cell collaboration, thereby reducing the interference of the user terminal.

In response to the throughput type being heavy-load high uplink throughput or heavy-load high downlink throughput, the wireless communication channel is adjusted in at least one of the following ways: releasing uplink wireless resources, releasing downlink wireless resources.

Specifically, releasing the uplink wireless resources and releasing the downlink wireless resources can enable the gNB of the adjacent cell to release the user terminal (UE) carried on the high-interference overlapping channel subband resources through inter-cell collaboration, thereby reducing the interference of the user terminal.

In response to the throughput type being heavy-load low full-link throughput, the wireless communication channel is adjusted in at least one of the following ways: adjusting the allocation position of the sub-band resources of the wireless communication channel, adjusting the duplex mode of the uplink wireless resources, adjusting the duplex mode of the downlink wireless resources, adjusting the number of uplink wireless resources, and adjusting the number of downlink wireless resources.

Step 17: The feedback field of the gNB correction trigger is set to Triggered and Pending Confirmation.

Step 18: The Enable field of the gNB Modify Trigger is enabled;

Step 19: The gNB sends a trigger to all UEs in the cell.

Step 20: All user terminals (UEs) in the cell receive the trigger and parse all fields;

Step 21: All user terminals (UEs) in the cell determine at least one adjustment method for their own matching;

Step 22: All user terminals (UEs) in the cell modify the feedback field of the trigger to be triggered and confirmed;

Step 23: All UEs in the cell feed back the trigger to the gNB.
