Description

Method and device for allocating time-frequency resources

technical field

Embodiments of the present invention relate to the field of communication technologies, and in particular, to a method and device for allocating time-frequency resources.

Background technique

With the rapid development of mobile communication technologies, the number of user equipment (user equipment, UE) using multimedia mobile services is also increasing continuously. There are a large number of various mobile services, and they continue to grow, which brings great challenges to operators. Therefore, a strategy is needed to use the existing spectrum more efficiently.

Fig. 1 shows a cell pattern using a conventional method of allocating time-frequency resources. When the traffic of Universal Mobile Telecommunications System (UMTS) drops below a preset level, UMTS radio access technology (radio access technology, RAT) releases 5M time-frequency resources. In this mode, the released 5M cell time-frequency resources are exclusively and alternately allocated to Long Term Evolution (LTE) RAT or UMTS RAT according to a certain parameter. For example, when UMTS RAT cell traffic is considered to be low, UMTS RAT releases 5M cell time-frequency resources and allocates them to LTE RAT; when UMTS RAT cell traffic is considered large, LTE RAT releases 5M cell time-frequency resources and allocates them to UMTS RAT . However, the 5M time-frequency resource can only be allocated to one RAT at any time, therefore, the overall throughput of the cell is low.

detailed description

The technical solutions in the embodiments of the present invention will be clearly described below with reference to the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Figure 2A shows a simplified block diagram of an apparatus 200 according to one embodiment of the present invention. Fig. 2B shows a scenario in which an embodiment of the present invention may be applied. Wherein, FIG. 2A is described in conjunction with FIG. 2B.

The apparatus 200 can be used for allocating time-frequency resources on a frequency band of a cell. The cell belongs to a base station, where the base station is at least used for performing data transmission through a first random access technology (random access technology, RAT) and performing data transmission through a second RAT. For example, the first RAT and the second RAT may be Global system for mobile communications (Global system for mobile communications, GSM) RAT, Universal Mobile Telecommunications System (Universal Mobile Telecommunications System, UMTS) RAT and long-term introduction (Long Term Evolution, LTE) RAT any two. The LTE here refers to LTE in a frequency division duplex (frequency division duplex, FDD) mode, that is, the uplink channel bandwidth and the downlink channel bandwidth exist in pairs. In other words, base stations are used to enable integrated deployment of different RATs such as GSM RAT, UMTS RAT and LTETERAT. For example, the base station is a converged radio access network (single radio access network, SRAN) base station. In the following description, the first RAT refers to the UMTS RAT, and the second RAT refers to the LTE RAT. When the traffic of the UMTS RAT drops below a preset level, the UMTS RAT releases the frequency band. The frequency band to be allocated has a bandwidth compatible with data transmission through the first RAT and data transmission through the second RAT. For example, the minimum bandwidth compatible with data transmission via UMTSRAT and data transmission via LTE RAT is 5M.

In FIG. 2B , there are two cells, cell 222 and cell 228 , in this scenario. Cell 228 is a neighboring cell of cell 222, and cell 222 and cell 228 belong to base station 220 and base station 226, respectively. In this scenario, there is also a central control node 242 for controlling signaling processing. The central control node 242 may include but not limited to: a converged radio access network (radio access network, RAN) controller (single RAN controller, SRC), a network management system (network management system, NMS), a network element management system (element management system, EMS) or a mobility management entity (mobility management entity, MME).

In an example, the apparatus 200 may be implemented by the base station 220 to allocate time-frequency resources of the main serving cell 222 of the base station 220 . The device 200 may also be implemented by the base station 226 to allocate time-frequency resources of the primary serving cell 228 of the base station 226 . In another example, the central control node 242 of the apparatus 200 may allocate at least one of the time-frequency resources of the cell 222 and the time-frequency resources of the cell 228 .

For illustrative purposes, in the following description, the device 200 is used to allocate time-frequency resources of the cell 222, but it is not limited thereto. It should be understood that the present invention is also applicable to the base station 226, and is used for allocating the main The time-frequency resources of the serving cell 228, or applicable to the central control node 242, are used to allocate the time-frequency resources of the cell 228 or any other cell. There are one or more cell-center user equipment (cell-center user equipment, CCU) and one or more cell-edge user equipment (cell-edge user equipment, CEU) in the cell 222 . The base station 220 is used for data transmission through the first RAT and data transmission through the second RAT.

As shown in FIG. 2A , the device 200 includes a configuration unit 204 and an allocation unit 206 . The configuring unit 204 and the allocating unit 206 may be implemented by a processor, for example, a processor in the base station 220 or a processor in the central control node 242 . As used herein, the term "processor" refers to one or more devices, circuits, and/or processing cores, such as computer program instructions, for processing data.

The configuring unit 204 is configured to configure at least three types of time-frequency resources based on the time-frequency resources on the frequency band. The three types of time-frequency resources include the first type of time-frequency resources in the first time period, the second type of time-frequency resources in the second time period, and the third type of time-frequency resources in the third time period. The first time period, the second time period and the third time period may occur cyclically. The first time period, the second time period and the third time period are expressed in units of subframes or time slots, but are not limited thereto.

In an example, the configuration unit 204 is configured to set the length of the first time period, the length of the second time period and the length of the third time period. The configuration unit 204 is further configured to set a sequence among the first time period, the second time period and the third time period in the time domain. In one example, the length and order of the different time periods are set randomly. For example, the length of the first time period corresponding to the first type of time-frequency resource can be randomly set as two time slots, and the order is: the first time period is prior to the second time period, and the second time period is prior to the third time period . In another example, the length and sequence of the different time periods are set according to a predetermined configuration.

The allocating unit 206 is configured to allocate the first type of time-frequency resources in the first time period to one or more CCUs that perform data transmission with the first base station in the cell 222 through the first RAT, and to allocate the time-frequency resources of the first type to the cell through the second RAT One or more CCUs performing data transmission by the first base station in 222; allocating the second type of time-frequency resources in the second time period to one or more CCUs performing data transmission with the first base station in cell 222 through the first RAT CEUs; and allocating a third type of time-frequency resource in a third time period to one or more CEUs that perform data transmission with the first base station in the cell 222 through the second RAT.

Fig. 2C shows an example of how to allocate time-frequency resources into three types of time-frequency resources. In the example in FIG. 2C , the first time period, the second time period and the third time period appear twice in a cycle, and the cycle period is 2 subframes (ie, 4 time slots). FIG. 2C shows a first period T1 from time slot TS1 of subframe 1 to time slot TS2 of subframe 2, and a second period T2 from time slot TS1 of subframe 3 to time slot TS2 of subframe 4. The first time period includes time slot TS1 of subframe 1 and time slot TS2 of subframe 1 in the first period T1, and time slot TS1 of subframe 3 and time slot TS2 of subframe 3 in the second period T2. The second time period includes time slot TS1 of subframe 2 in the first period T1 and time slot TS1 of subframe 4 in the second period T2. The third time period includes time slot TS2 of subframe 2 in the first period T1, and time slot TS2 of subframe 4 in the second period T2.

Therefore, in the first time period, one or more CCUs that perform data transmission with the base station 220 through the first RAT and one or more CCUs that perform data transmission with the base station 220 through the second RAT use the first type of time-frequency resources; In the second time period, one or more CEUs that perform data transmission with the base station 220 through the first RAT use the second type of time-frequency resources; in the third time period, one or more CEUs that perform data transmission with the base station 220 through the second RAT The CEU uses the third type of time-frequency resources.

In the downlink data transmission operation, assuming that the time-frequency resources of the cell 222 are allocated according to the above method, in the first time period, the base station 220 uses the first type of time-frequency resources to send downlink data to the cell 222 for data transmission through the first RAT At the same time, the base station 220 also uses the first type of time-frequency resource to send downlink data to the CCU of the cell 222 that performs data transmission through the second RAT. In the second time period, the base station 220 uses the second type of time-frequency resources to send downlink data to the CEUs performing data transmission through the first RAT. In the third time period, the base station 220 uses the third type of time-frequency resources to send downlink data to CEUs performing data transmission through the second RAT. The UE 224 monitors a physical downlink control channel (physical downlink control channel, PDCCH) to acquire indication information of a physical downlink shared channel (physical downlink shared channel, PDSCH), so as to receive corresponding downlink data in the PDSCH according to the acquired indication information.

In the uplink data transmission operation, after the UE 224 completes downlink synchronization and acquires system information from a physical broadcast channel (physical broadcast channel, PBCH) and PDSCH, the UE 224 obtains resource allocation information and access configuration information. The resource allocation information indicates the type of time-frequency resource for UE 224 to transmit uplink data. When the UE 224 requests random access to the network, the UE 224 sends an uplink random access preamble to the base station 220 through a physical random access channel (PRACH) according to the access configuration information for uplink synchronization. After the UE 224 successfully accesses the network, for example, when the UE 224 needs to use a service, the UE 224 sends a service request (service request, SR) through a physical uplink control channel (PUCCH) to request uplink scheduling. Then, the UE 224 monitors the PDCCH to acquire indication information of a physical uplink shared channel (PUSCH), so as to transmit uplink data in the PUSCH according to the resource allocation information and the acquired indication information.

For example, if the UE 224 is a CCU performing data transmission through the first RAT or a CCU performing data transmission through the second RAT, the resource allocation information indicates that the UE 224 uses the first type of time-frequency resources to transmit uplink data. If the UE 224 is a CEU that performs data transmission through the first RAT, the resource allocation information instructs the UE 224 to use the second type of time-frequency resources to transmit uplink data. If the UE 224 is a CEU that performs data transmission through the second RAT, the resource allocation information instructs the UE 224 to use the third type of time-frequency resource to transmit uplink data.

Therefore, by allocating time-frequency resources according to the method described above, at any time in the first time period, both the CCUs performing data transmission through the first RAT and the CCUs performing data transmission through the second RAT can compete for the first type of time-frequency resources for data transfer. From the perspective of the time domain, the time-frequency resource allocated to each RAT in the cell center is extended. As long as the throughput rate of the control cell center is higher than the threshold, the system throughput capability of the cell center is improved.

For example, in the prior art, time-frequency resources are exclusively and alternately allocated to the first RAT and the second RAT in a time-division manner. In a certain time period t, the time-frequency resources are exclusively allocated to the first RAT in the time period t1, and exclusively allocated to the second RAT in the time period t2, where t=t1+t2. For the purpose of illustration, when time-frequency resources are exclusively allocated to one of the first RAT and the second RAT, assuming that the throughput rate of the first RAT is R1, and the throughput rate of the second RAT is R2, then in the prior art, the time period t During this period, the system throughput capacity of the cell center is equal to R1*t1+R2*t2.

In one embodiment of the present application, due to the competitive interference between the first RAT and the second RAT in the first time period, the throughput rate of the first RAT and the throughput rate of the second RAT may be slightly reduced by η1*R1 respectively and η2*R2, where η1 and η2 represent the attenuation factors of the first RAT and the second RAT throughput, respectively. However, since the two RATs share time-frequency resources during the time period t, the time allocated for each RAT is extended to t. Thus, according to an embodiment of the present application, the system throughput of the cell center increases to η1*R1*t+η2*R2*t in the time period t. Wherein, as long as the control attenuation factors η1 and η2 meet the following conditions:

η1*R1+η2*R2>R1*t1/t+R2*t2/t,

Then the system throughput capacity of the cell center is improved.

For example, assuming R1=R2=R, the attenuation factors η1 and η2 must satisfy η1+η2>1. Therefore, in the prior art, the system throughput capability of the cell center is equal to R*t during the time period t. According to an embodiment of the invention, the system throughput capability of the cell center is greater than R*t during the time period t. Therefore, the system throughput capability of the cell center is improved.

On the other hand, the time-frequency resources of the second type and the time-frequency resources of the third type are respectively allocated to CEUs that perform data transmission through the first RAT and CEUs that perform data transmission through the second RAT. Therefore, the CEU will not suffer strong interference from other UEs that transmit data through different RATs. Correspondingly, the throughput rate and throughput of the cell edge CEU are improved, and the overall throughput of the cell is also improved.

Returning to FIG. 2A , optionally, the device 200 further includes a threshold control unit 202 . The threshold control unit 202 is used for setting the threshold of the cell 222 . The threshold is used to determine whether a UE in cell 222, such as UE 224, is a CCU or a CEU. In an example, the threshold is expressed in the form of a signal to interference plus noise ratio (SINR). By comparing the SINR of UE 224 with the threshold value, it is determined that UE 224 is a CCU or CEU. If the SINR of the UE 224 is greater than the threshold, the UE 224 is a CCU; if the SINR of the UE 224 is less than or equal to the threshold, the UE 224 is a CEU. In another example, the threshold is expressed in the form of a distance between UE 224 and base station 220 . By comparing the distance between UE 224 and base station 220 with the size of the threshold, it is determined that UE 224 is a CCU or CEU. If the distance is less than the threshold, the UE 224 is a CCU; if the distance is greater than or equal to the threshold, the UE 224 is a CEU.

Optionally, the apparatus 200 further includes a scheduling unit 208 . The scheduling unit 208 is configured to perform scheduling to obtain load information of the cell 222, for example, to obtain load information through downlink scheduling. The base station 220 sends a downlink reference signal, such as a pilot signal, to each UE in the cell 222 . Each UE in the cell 222 measures the SINR value, and reports a channel quality indicator (channel quality indicator, CQI) as load information to the base station 220 based on the SINR value. For another example, load information is obtained through uplink scheduling. The base station measures the SINR of the uplink reference signal sent by the UE, such as the sounding reference signal, to obtain load information. In an example, after the load information is obtained, if the timer expires, at least one of the configuration unit 204 and the threshold control unit 202 performs the following operations. In another example, if the timer has not expired and the load information indicates that the specific load of the cell 222 is greater than a preset level, an emergency operation is triggered, and at least one of the configuration unit 204 and the threshold control unit 202 is activated to be executed immediately Do the following.

In an example, the load information indicates the load of the first type of time-frequency resources, the load of the second type of time-frequency resources, and the load of the third type of time-frequency resources. The configuration unit 204 is configured to adjust the length of the first time period corresponding to the first type of time-frequency resource, the length of the second time period corresponding to the second type of time-frequency resource, and the length of the third time period corresponding to the third type of time-frequency resource according to the load information. At least one of the lengths of the time period. For example, if the load information indicates that the load of a specific type of time-frequency resource is greater than the first level, the length of the time period corresponding to the specific type of time-frequency resource can be adjusted to a larger value; When the load of the type of time-frequency resource is less than the second level, it is adjusted to a smaller value. Taking CCU as a specific example, when the load information indicates that the load of the first type of time-frequency resource allocated to the CCU is greater than the first level, the length of the first time period may be adjusted from the first length to a second length greater than the first length . When the load information indicates that the load of the first type of time-frequency resource allocated to the CCU is smaller than the second level, the length of the first time period may be adjusted from the first length to a third length shorter than the first length.

In another example, the load information indicates the load of the first type of time-frequency resource, and the loads of the second type of time-frequency resource and the third type of time-frequency resource. Wherein, the threshold control unit 202 is configured to adjust the threshold of the second cell 222 according to the obtained load information. When the load information indicates that the specific load of the UE is greater than the first preset level or less than the second preset level, the threshold of the cell 222 is adjusted. In one example, the threshold includes a SINR threshold. If the SINR of the UE 224 is greater than the SINR threshold, the UE 224 is a CCU; if the SINR of the UE 224 is less than or equal to the SINR threshold, the UE 224 is a CEU. When the load information indicates that the load of the first type of time-frequency resource is greater than the first preset level or the loads of the second type of time-frequency resource and the third type of time-frequency resource are less than the second preset level, the SINR threshold may be changed from the first The value is adjusted to a second value greater than the first value. In this way, when the SINR of some CCUs in the cell 222 is greater than the first value but smaller than the second value, these CCUs become CEUs, so as to reduce the load of CCUs in the cell 222 . When the load information indicates that the loads of the second type of time-frequency resources and the third type of time-frequency resources are greater than the third preset level or that the load of the first type of time-frequency resources is less than the fourth preset level, then the threshold can be taken from the first The value is adjusted to a third value smaller than the first value. In this way, when the SINR of some CEUs in the cell 222 is greater than the third value but smaller than the fourth value, these CEUs become CCUs, so as to reduce the CEU load in the cell 222 .

In another example, the threshold includes a distance threshold. If the distance between the UE 224 and the base station 220 is less than the distance threshold, the UE 224 is a CCU; if the distance between the UE 224 and the base station 220 is greater than or equal to the distance threshold, then the UE 224 is a CEU. When the load information indicates that the load of the first type of time-frequency resource is greater than the first preset level or the loads of the second type of time-frequency resource and the third type of time-frequency resource are smaller than the second preset level, the distance threshold can be taken from the fourth The value is adjusted to a fifth value smaller than the fourth value. In this way, when the distance between some CCUs in the cell 222 and the base station 220 is greater than the fifth value but smaller than the fourth value, these CCUs become CEUs to reduce the CCU load in the cell 222 . When the load information indicates that the loads of the second type of time-frequency resources and the third type of time-frequency resources are greater than the third preset level or that the load of the first type of time-frequency resources is less than the fourth preset level, then the distance threshold can be changed from the fourth The value is adjusted to a sixth value greater than the fourth value. In this way, when the distance between some CEUs in the cell 222 and the base station 220 is greater than the fourth value but smaller than the sixth value, these CEUs become CCUs to reduce the CEU load in the cell 222 .

Optionally, the apparatus 200 further includes a receiving unit 212 and a sending unit 210 . The receiving unit 212 is configured to receive one or more requests from the base station 226 . The sending unit 210 is configured to: send a response to the base station 226 after the receiving unit 212 receives one or more requests.

For example, the receiving unit 212 is configured to receive from the base station 226 a first request indicating that the threshold of the cell 222 will be adjusted. The first request includes reference information indicating interference experienced by one or more CEUs in cell 228 . After the receiving unit 212 receives the first request, the threshold control unit 202 adjusts the threshold of the cell 222 .

In a specific example, when the CEU 230 in the cell 228 is interfered by the CEU in the cell 222, and the interference information indicates that the interference caused by the CEU in the cell 222 to the CEU 230 is greater than a preset level, then the CEU in the cell 222 The SINR threshold is adjusted from the seventh value to an eighth value smaller than the seventh value. In this way, when the SINR of some CEUs in the cell 222 is greater than the eighth value but less than the seventh value, these CEUs become CCUs. Or, the distance threshold of the cell 222 is adjusted from the ninth value to a tenth value greater than the ninth value. In this way, when the distance between some CEUs in the cell 222 and the base station 220 is greater than the ninth value but less than the tenth value, these CEUs become CCUs. Generally speaking, the data transmission power of the CCU is lower than that of the CEU. As a result, fewer CEUs in cell 222 transmit data at higher power, reducing interference to CEUs 230 in cell 228 . Moreover, since the number of CEUs in the cell 222 is reduced, the service requests in the cell 222 are correspondingly reduced, thereby reducing the interference to the CEUs in the cell 228 . After the threshold control unit 202 adjusts the threshold of the cell 222 , the sending unit 210 returns a response to the base station 226 .

Optionally, the receiving unit 212 is further configured to receive from the base station 226 a second request indicating that the three types of time-frequency resources of the cell 222 will be reconfigured. The second request includes time-frequency resource configuration information of the cell 228 . The configuration unit 204 is configured to: after the receiving unit 212 receives the second request, adjust in the time domain the first time period corresponding to the first type of time-frequency resource, the second time period corresponding to the second type of time-frequency resource, and the second time period corresponding to the second type of time-frequency resource. The order among the third time periods corresponding to the three types of time-frequency resources makes the part of the second time period allocated to one or more CEUs in the first cell for data transmission through the first RAT and the part of the second time period allocated to the first cell through the first RAT At least one of the part of the third time period of the one or more CEUs in which the second RAT performs data transmission is staggered from the time period of the one or more CEUs allocated to the second cell. 3A and 3B show examples of how to adjust the order of different types of time-frequency resources in the time domain.

In the example of FIG. 3A , in the first period T1 and the second period T2 , the time-frequency resources of the cell 222 and the time-frequency resources of the cell 228 are allocated, as shown in FIG. 3A . Therefore, CEUs in cell 222 for data transmission over the first RAT are interfered by CEUs in cell 228 for data transmission over the first RAT. CEUs in cell 222 using the second RAT are interfered by CEUs in cell 228 using the second RAT. After receiving the second request including the time-frequency resource configuration information of the cell 228, the order of multiple types of time-frequency resources in the time domain is adjusted in a subsequent period. For example, in the subsequent third period T3 and fourth period T4, the order in the cell 222 is adjusted so that the second time period corresponding to the second type of time-frequency resource is earlier than the third time period corresponding to the third type of time-frequency resource , and the third time period is earlier than the first time period corresponding to the first type of time-frequency resource. Therefore, the position of the second time period corresponding to the second type of time-frequency resource in the cell 222 is staggered from the position of the second time cycle corresponding to the second type of time-frequency resource in the cell 228, and at the same time, the third type of time-frequency resource in the cell 222 is The position of the corresponding third time period is staggered from the position of the third time period corresponding to the third type of time-frequency resource in the cell 228 . This avoids interference between CEUs in cell 222 and CEUs in cell 228 .

In some cases, when the configuration unit 204 adjusts the sequence, the configuration unit 204 is also configured to adjust the length of the first time period corresponding to the first type of time-frequency resource, the length of the second time period corresponding to the second type of time-frequency resource and the length of the second time period corresponding to the second type of time-frequency resource. At least one of the lengths of the third time period corresponding to the third type of time-frequency resource. How to adjust the length of each time period has been exemplified above, and will not be repeated here.

Fig. 4 shows a flow chart of a method for allocating time-frequency resources on a frequency band of a first cell, such as cell 222. FIG. 4 is described in conjunction with FIGS. 2A to 3B . There are one or more CCUs and one or more CEUs in the first cell. The first cell belongs to a first base station, such as base station 220, and is used for data transmission through a first radio access technology (radio access technology, RAT) and data transmission through a second RAT. The method is performed by a device. In one example, the apparatus includes a base station, such as base station 220 or base station 226 . In another example, the apparatus includes a central control node, such as central control node 242 . The central control node may include but not limited to SRC, NMS, EMS or MME.

As shown in Figure 4, the method includes:

In S41, the device configures at least three types of time-frequency resources based on the time-frequency resources on the frequency band. The three types of time-frequency resources include the first type of time-frequency resources in the first time period, the second type of time-frequency resources in the second time period, and the third type of time-frequency resources in the third time period. In one example, the first time period, the second time period, and the third time period occur cyclically.

For example, S41 includes: the device sets the length of the first time period corresponding to the first type of time-frequency resource, the length of the second time period corresponding to the second type of time-frequency resource, and the length of the third time period corresponding to the third type of time-frequency resource length. The device may also set a sequence among the first time period corresponding to the first type of time-frequency resource, the second time period corresponding to the second type of time-frequency resource, and the third time period corresponding to the third type of time-frequency resource.

In S42, the device allocates the first type of time-frequency resources in the first time period to one or more CCUs that perform data transmission with the first base station of the first cell through the first RAT, and to one or more CCUs that communicate with the first base station in the first cell through the second RAT. One or more CCUs for data transmission by the first base station of a cell.

In S43, the device allocates the second type of time-frequency resources in the second time period to one or more CEUs that perform data transmission with the first base station of the first cell through the first RAT.

In S44, the device allocates the third type of time-frequency resource in the third time period to one or more CEUs that perform data transmission with the first base station of the first cell through the second RAT. It should be understood that steps S42 to S44 may be executed sequentially, in parallel, in parallel, or simultaneously.

Therefore, from the perspective of the time domain, the time-frequency resource allocated to each RAT in the cell center is extended. As long as the throughput rate of the control cell center is higher than the threshold, the system throughput capability of the cell center is improved. On the other hand, the time-frequency resources of the second type and the time-frequency resources of the third type are respectively allocated to CEUs performing data transmission through the first RAT and CEUs performing data transmission through the second RAT. Therefore, the CEU will not be strongly interfered by other UEs that transmit data through different RATs. Accordingly, the throughput rate and throughput of the cell edge CEU are improved, and the overall throughput of the cell is also improved.

Optionally, the method also includes:

In S40, the device sets a threshold of the first cell. This threshold is used to determine whether a UE, such as UE 224, is a CCU or CEU. In one example, the threshold is expressed in the form of SINR. If the SINR of the UE 224 is greater than the threshold, the UE 224 is a CCU; if the SINR of the UE 224 is less than or equal to the threshold, the UE 224 is a CEU. In another example, the threshold is expressed in the form of a distance between UE 224 and base station 220 . If the distance is less than the threshold, the UE 224 is a CCU; if the distance is greater than or equal to the threshold, the UE 224 is a CEU.

Optionally, the method also includes:

In S45, the device performs scheduling to obtain load information. In one example, after the load information is obtained, if the timer expires, at least one of steps S451 and S461 is performed. In another example, if the timer has not expired and the load information indicates that the specific load of the cell 222 is greater than a preset level, an emergency operation is triggered, and at least one of steps S451 and S461 is immediately activated.

If the load information indicates the load of the first type of time-frequency resource, the load of the second type of time-frequency resource, and the load of the third type of time-frequency resource, then in S451, the device may adjust the corresponding load of the first type of time-frequency resource according to the load information. At least one of the length of the first time period, the length of the second time period corresponding to the second type of time-frequency resource, and the length of the third time period corresponding to the third type of time-frequency resource. For example, if the load information indicates that the load of a specific type of time-frequency resource is greater than the first level, the length of the time period corresponding to the specific type of time-frequency resource can be adjusted to a larger value; When the load of the type of time-frequency resource is less than the second level, it is adjusted to a smaller value.

If the load information indicates the load of the first type of time-frequency resource, and the loads of the second type of time-frequency resource and the third type of time-frequency resource, then in S461, the device may adjust the threshold of the first cell according to the load information. When the load information indicates that the specific load of the UE is greater than the first preset level or less than the second preset level, the threshold of the cell 222 is adjusted.

Optionally, the method also includes:

In S46, the device receives a first request from a second base station, such as base station 226, indicating that the threshold of the first cell is to be adjusted. The second cell, such as cell 228, belongs to the second base station and is a neighboring cell of the first cell. The first request includes interference information indicating interference experienced by one or more CEUs in the second cell. Then, in S461, the device adjusts the threshold of the first cell according to the load information. For example, when the CEU 230 in the cell 228 is interfered by the CEU in the cell 222, and the interference information indicates that the interference caused by the CEU in the cell 222 to the CEU 230 is greater than a preset level, the SINR threshold of the cell 222 is adjusted from the seventh value to an eighth value smaller than the seventh value, or adjust the distance threshold of the cell 222 from the ninth value to a tenth value greater than the ninth value. Therefore, some CEUs become CCUs. Since the data transmission power of the CCU is lower than that of the CEUs, the number of CEUs transmitting data with higher power in the cell 222 is reduced, reducing the interference to the CEUs 230 in the cell 228 . Moreover, since the number of CEUs in the cell 222 is reduced, the service requests in the cell 222 are correspondingly reduced, thereby reducing the interference to the CEUs in the cell 228 .

Optionally, the method also includes:

In S47, the device receives from the second base station a second request indicating that three types of time-frequency resources of the first cell are to be reconfigured. The second request includes time-frequency resource configuration information of the second cell. Then, in S471, after receiving the second request, the device may adjust the sequence among the three types of time-frequency resources in the first cell, so that the CEUs allocated to one or more CEUs in the first cell for data transmission through the first RAT at least one of the portion of the second time period and the portion of the third time period allocated to one or more CEUs in the first cell for data transmission over the second RAT and the time period of the one or more CEUs allocated to the second cell stagger. This avoids interference between CEUs in cell 222 and CUEs in cell 228 .

Optionally, the method also includes:

In S472, the device further adjusts the length of the first time period corresponding to the first type of time-frequency resource, the length of the second time period corresponding to the second type of time-frequency resource, and the length of the third time period corresponding to the third type of time-frequency resource. at least one of the lengths.

It should be understood that not all steps in FIG. 4 are required, and these steps may be executed in sequence, in parallel, in parallel, or simultaneously.

It should be understood that the foregoing description is for illustrative purposes only. Time-frequency resources can be configured as multiple types of time-frequency resources by different means or in different forms. Regardless of whether at least one type of time-frequency resource is allocated to at least one or more CCUs for data transmission over the first RAT or one or more CCUs for data transmission over the second RAT, or at least one type of time-frequency resource Allocating frequency resources to CEUs for data transmission through each RAT is within the scope of this application.

In another embodiment, two types of time-frequency resources are configured based on the time-frequency resources on the frequency band. The two types of time-frequency resources include the fourth type of time-frequency resources in the fourth time period and the fifth type of time-frequency resources in the fifth time period. Allocating the fourth type of time-frequency resource in the fourth time period to the UE performing data transmission through the first RAT; and allocating the fifth type of time-frequency resource in the fifth time period to the UE performing data transmission through the second RAT. This mode is also applicable to steps except S40 to S44 described in FIG. 4 , which will not be repeated here.
