The irregular uplink time slot is an uplink time slot of an uplink time slot position except a preset uplink time slot position in the target frame. Subsequently, when the maximum signal-to-noise ratio of the terminal in the target irregular uplink time slot is greater than the preset signal-to-noise ratio, the base station can schedule the time slot resource of the target irregular uplink time slot to the terminal.

Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
It should be noted that, in the embodiments of the present application, words such as "exemplary" or "such as" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "e.g." in an embodiment should not be taken as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.
In order to clearly describe the technical solution of the embodiment of the present application, in the embodiment of the present application, the words "first", "second", etc. are used to distinguish identical items or similar items having substantially the same function and effect, and those skilled in the art will understand that the words "first", "second", etc. are not limited in number and execution order.
As described in the background art, in the current 5G traffic, most traffic is downstream traffic, and thus, the structural configuration of frames in the 5G traffic is mainly as follows. The structure of a 2.5ms bi-periodic frame, e.g., of a TDD system, is configured as DDDSU DDSUU. Wherein D represents a downlink time slot, U represents an uplink time slot, and S represents a special time slot.
For some cells that are dominated by uplink traffic, a large amount of uplink traffic can be satisfied by converting the downlink time slots in the frame to uplink time slots. However, the structural configuration of the frame is not changed due to surrounding cells. Therefore, the downlink time slot of the surrounding cell will interfere with the converted uplink time slot, thereby affecting the data transmission quality.
In view of the above problems, the present application provides a method for reducing slot interference, including: when the uplink traffic is greater than the first preset traffic, the base station may configure a frame structure of the current frame to obtain the target frame. The number of uplink time slots in the target frame is greater than the number of uplink time slots of the current frame. The base station may then determine the maximum signal-to-noise ratio of the terminal in the irregular uplink time slot. The irregular uplink time slot is an uplink time slot of an uplink time slot position except a preset uplink time slot position in the target frame. Subsequently, when the maximum signal-to-noise ratio of the terminal in the target irregular uplink time slot is greater than the preset signal-to-noise ratio, the base station can schedule the time slot resource of the target irregular uplink time slot to the terminal.
From the above, the base station can increase the number of uplink timeslots in the current frame when the uplink traffic is large, so as to satisfy the large uplink traffic. Then, since the irregular uplink time slot is an uplink time slot of an uplink time slot position other than the preset uplink time slot position, the base station can schedule the target irregular uplink time slot to the terminal when the maximum signal-to-noise ratio of the terminal in the target irregular uplink time slot is larger.
Because the maximum signal-to-noise ratio of the terminal in the target irregular uplink time slot is larger, and the signal-to-noise ratio is the ratio of the uplink signal power sent by the terminal to the noise power in the uplink time slot, when the maximum signal-to-noise ratio of the terminal in the target irregular uplink time slot is larger, the uplink signal sent by the terminal is less interfered by the noise in the downlink time slot, the demodulation accuracy is higher, and the data transmission quality is higher.
The method for reducing the time slot interference is suitable for a system for reducing the time slot interference. Fig. 1 shows one configuration of the reduced slot interference system. As shown in fig. 1, the reduced slot interference system includes: a base station 101 and a plurality of terminals 102.
Wherein a base station 101 and a plurality of terminals 102 are respectively communicatively connected. The plurality of terminals 102 are terminals in a target cell in the base station 101.
In the present application, the base station 101 may acquire the background noise value of the irregular uplink timeslot, the uplink signal receiving power sent by the terminal, and the transmit power margin of the terminal sent by the terminal. Base station 101 then determines the maximum signal-to-noise ratio for terminal 102 in the irregular uplink time slot. Subsequently, the base station 101 may schedule the slot resources of the irregular uplink slot or the slot resources of the regular uplink slot for the plurality of terminals 102 according to the maximum signal-to-noise ratio of the plurality of terminals 102 in the irregular uplink slot.
The plurality of terminals 102 may transmit power headroom of the terminals to the base station 101 through slot resources of an irregular uplink slot scheduled by the base station 101 for the plurality of terminals 102 and transmit uplink traffic to the base station 101.
Alternatively, the terminal 102 may be a device that provides voice and/or data connectivity to a user, a handheld device with wireless connectivity, or other processing device connected to a wireless modem. The terminal may communicate with one or more core networks via a radio access network (radio access network, RAN). Terminals may be mobile terminals such as mobile telephones (or "cellular" telephones) and computers with mobile terminals, as well as portable, pocket, hand-held, computer-built-in or car-mounted mobile devices which exchange voice and/or data with radio access networks, e.g. cell phones, tablet computers, notebook computers, netbooks, personal digital assistants (personal digital assistant, PDA).
The basic hardware structure of the base station 101 includes elements included in the slot interference reduction device shown in fig. 2 or fig. 3. The hardware configuration of the base station 101 will be described below taking the slot interference reduction device shown in fig. 2 and 3 as an example.

The device for reducing time slot interference comprises a processor 21, a memory 22, a communication interface 23 and a bus 24. The processor 21, the memory 22 and the communication interface 23 may be connected by a bus 24.
The processor 21 is a control center of the slot interference reducing device, and may be one processor or a collective term of a plurality of processing elements. For example, the processor 21 may be a general-purpose central processing unit (central processing unit, CPU), or may be another general-purpose processor. Wherein the general purpose processor may be a microprocessor or any conventional processor or the like.
As one example, processor 21 may include one or more CPUs, such as CPU 0 and CPU 1 shown in fig. 2.

In a possible implementation, the memory 22 may exist separately from the processor 21, and the memory 22 may be connected to the processor 21 by a bus 24 for storing instructions or program code. The processor 21, when calling and executing instructions or program code stored in the memory 22, is capable of implementing the method for reducing slot interference provided in the embodiments of the present application described below.
In the embodiment of the present application, the software program stored in the memory 22 is different for the base station 101, so the functions realized by the base station 101 are different. The functions performed with respect to the respective devices will be described in connection with the following flowcharts.
In another possible implementation, the memory 22 may also be integrated with the processor 21.
The communication interface 23 is used for connecting the time slot interference reduction device with other devices through a communication network, wherein the communication network can be an ethernet, a wireless access network, a wireless local area network (wireless local area networks, WLAN) and the like. The communication interface 23 may include a receiving unit for receiving data, and a transmitting unit for transmitting data.

The bus may be classified as an address bus, a data bus, a control bus, etc. For ease of illustration, only one thick line is shown in fig. 2, but not only one bus or one type of bus.
Fig. 3 shows another hardware configuration of the apparatus for reducing slot interference in the embodiment of the present application. As shown in fig. 3, the means for reducing slot interference may comprise a processor 31 and a communication interface 32. The processor 31 is coupled to a communication interface 32.

The communication interface 32 is used to provide data to the processor 31. The communication interface 32 may be an internal interface of the slot interference reduction device or an external interface (corresponding to the communication interface 23) of the slot interference reduction device.
It should be noted that the structure shown in fig. 2 (or fig. 3) does not constitute a limitation of the slot interference reduction device, and the slot interference reduction device may include more or less components than those shown in fig. 2 (or fig. 3), or may combine some components, or may be a different arrangement of components.
The following describes a method for reducing timeslot interference according to an embodiment of the present application in detail with reference to the accompanying drawings.
The method for reducing the time slot interference provided by the embodiment of the application is applied to the base station 101 in the system for reducing the time slot interference shown in fig. 1, and as shown in fig. 4, the method for reducing the time slot interference provided by the embodiment of the application comprises the following steps:
S401, when the uplink traffic is greater than a first preset traffic, the base station configures a frame structure of a current frame to obtain a target frame.
The number of uplink time slots in the target frame is greater than that of the current frame.
Specifically, the base station may obtain an uplink traffic of the terminal in the target cell. When the uplink traffic of the terminal in the target cell is greater than the first preset traffic, the number of uplink time slots in the current frame in the target cell is greater than or equal to the minimum value of the number of uplink time slots, and the number of uplink time slots in the current frame in the target cell is less than the maximum value of the number of uplink time slots, the base station can determine that the uplink traffic in the target cell is more. Therefore, the base station can configure the frame structure of the current frame in the target cell, thereby increasing the number of uplink slots in the current frame, so that the base station can schedule more uplink slots to the terminal. In this way, the terminal may transmit more uplink traffic to the base station through more uplink timeslots.
Optionally, the base station may obtain an average uplink physical resource block (Physical Resource Block, PRB) utilization of the terminal in the target cell in the first preset time period, and may determine that the uplink traffic in the target cell is greater than the first preset traffic when the average uplink PRB utilization of the terminal in the target cell in the first preset time period is greater than the first preset threshold.
The uplink PRB utilization ratio refers to a ratio of the number of uplink PRBs actually occupied by the terminal in the target cell to the number of available uplink PRBs in the target cell. The first preset time period is a first preset time period before the current time.
Optionally, the base station may acquire the uplink traffic of the terminal in the target cell once after the second preset period of time passes, that is, periodically acquire the uplink traffic of the terminal in the target cell.
Alternatively, the target frame may be a frame structure in the current period, or may be a frame structure in a period next to the current period, which is not limited in the embodiment of the present application.
It should be noted that, when the number of uplink timeslots in the current frame is equal to the maximum number of uplink timeslots and the uplink traffic of the terminal in the target cell is greater than the first preset traffic, the base station does not configure the frame structure of the current frame in the target cell.
Correspondingly, when the uplink traffic of the terminal in the target cell is smaller than or equal to the first preset traffic, the base station does not configure the frame structure of the current frame in the target cell.
Optionally, when the uplink traffic of the terminal in the target cell is smaller than the second preset traffic and the number of uplink time slots in the current frame is greater than the minimum value of the number of uplink time slots, the uplink traffic in the target cell is smaller. At this time, the base station may configure the frame structure of the current frame in the target cell, so as to reduce the number of uplink timeslots in the current frame and increase the number of downlink timeslots, so that the base station may transmit services to the base station through more downlink timeslots.
Wherein the second preset traffic is less than the first preset traffic.
For example, assuming a TDD system 2.5ms bi-periodic field with a current frame of 30 kilohertz (kHz) subcarrier spacing (Subcarrier Spacings, SCS), when the minimum value of the number of uplink slots in the current frame is 2 and the maximum value of the number of uplink slots in the current frame is 6, the frame structure of the current frame may be: when the number of uplink slots in the current frame is 2, the frame structure of the current frame is DDDSU. When the number of uplink slots in the current frame is 3, the frame structure of the current frame is DDDSU DDSUU. When the number of uplink time slots in the current frame is 4, the frame structure of the current frame is DDSUU. When the number of uplink time slots in the current frame is 5, the frame structure of the current frame is DDSUU DSUUU. When the number of uplink time slots in the current frame is 6, the frame structure of the current frame is DSUUU.
When the minimum value of the uplink time slot number in the current frame is 3 and the maximum value of the uplink time slot number in the current frame is 6, the frame structure of the current frame may also be: when the number of uplink slots in the current frame is 3, the frame structure of the current frame is DDDSU DDSUU. When the number of uplink time slots in the current frame is 4, the frame structure of the current frame is DDSUU. When the number of uplink time slots in the current frame is 5, the frame structure of the current frame is DDSUU DSUUU. When the number of uplink time slots in the current frame is 6, the frame structure of the current frame is DSUUU.
Since the frame structures of the front half frame and the rear half frame of the TDD system 2.5ms double period are the same, the base station can perform the same operation on the front half frame and the rear half frame at the same time.
S402, the base station determines the maximum signal-to-noise ratio of the terminal in the irregular uplink time slot.
The irregular uplink time slot is an uplink time slot of an uplink time slot position except a preset uplink time slot position in the target frame.
Specifically, since the irregular uplink time slot is an uplink time slot of an uplink time slot position other than the preset uplink time slot position in the target frame, the uplink time slot position is still a downlink time slot in the frame structure of the surrounding cell. In this way, the downlink time slot of the uplink time slot position in the surrounding cell will interfere with the irregular uplink time slot of the uplink time slot position in the target cell, so that the noise of the terminal for transmitting the service in the irregular uplink time slot is larger, the interference is larger, and finally the transmission quality of the service is affected.
In this case, the base station may determine the influence the terminal is affected in the irregular uplink time slot by the maximum signal-to-noise ratio of the terminal in the irregular uplink time slot. When the maximum signal-to-noise ratio is larger, the terminal has less interference to the transmission service in the irregular uplink time slot, and the transmission quality of the transmission service is higher.
When the number of uplink slots in the target frame is the minimum value of the number of uplink slots, the base station may determine that no irregular uplink slots exist in the target frame.
Optionally, the preset uplink time slot position is the uplink time slot position when the uplink time slot number in the target frame is the minimum value of the uplink time slot number, and may be the same position as the uplink time slot position in the frame of the surrounding cell.
Optionally, when configuring the current frame, the base station may preferentially configure the time slot of the preset uplink time slot position as the uplink time slot.
It should be noted that, the maximum signal-to-noise ratio of the same terminal in different irregular uplink timeslots is different, and the maximum signal-to-noise ratio of different terminals in the same irregular uplink timeslot is different.
S403, when the maximum signal-to-noise ratio of the terminal in the target irregular uplink time slot is greater than the preset signal-to-noise ratio, the base station schedules the time slot resource of the target irregular uplink time slot to the terminal.
Specifically, the greater the maximum signal-to-noise ratio of the terminal in the irregular uplink time slot, the higher the transmission quality of the traffic transmitted by the terminal in the irregular uplink time slot. Therefore, when the maximum signal-to-noise ratio of the terminal in the target irregular uplink time slot is greater than the preset signal-to-noise ratio, the base station can determine that the transmission quality is higher when the terminal transmits the service in the target irregular uplink time slot. Thereafter, the base station may schedule the slot resources of the target irregular uplink slot to the terminal so that the terminal may transmit traffic in the target irregular uplink slot.
Alternatively, the preset signal-to-noise ratios of different irregular uplink timeslots may be the same or different, which is not limited by the embodiment of the present application.
Alternatively, when the preset signal-to-noise ratios of different irregular uplink timeslots may be different, the terminals corresponding to the different target irregular uplink timeslots are different. Accordingly, one terminal may correspond to a plurality of different target irregular uplink timeslots.
When the irregular uplink time slot does not exist in the target frame, the base station directly schedules the regular uplink time slot to the terminal.
Exemplary, when the preset signal-to-noise ratios of different irregular uplink timeslots are different, it is assumed that the terminals in the target cell are each U 1 、U 2 A plurality of irregular uplink time slots are respectively N 1 、N 2 ，N 1 Corresponding to a preset signal-to-noise ratio of D 1 ，N 2 Corresponding to a preset signal-to-noise ratio of D 2 Terminal U 1 Non-regular uplink time slot N 1 The maximum signal to noise ratio of (a) is X 1 Terminal U 1 Non-regular uplink time slot N 2 The maximum signal to noise ratio of (a) is X 2 Terminal U 2 The most significant in the irregular uplink time slot N1Large signal-to-noise ratio of X 3 Terminal U 2 Non-regular uplink time slot N 2 The maximum signal to noise ratio of (a) is X 4 。
When X is 1 Greater than D 1 ，X 2 Greater than D 2 When the base station determines the irregular uplink time slot N 1 The corresponding terminal is U 1 、U 2 . I.e. the irregular uplink time slot N 1 Is U (U) 1 、U 2 Target irregular uplink time slots of (a). When X is 3 Greater than D 1 ，X 4 Less than D 2 When the base station determines the irregular uplink time slot N 2 The corresponding terminal is U 1 . I.e. the irregular uplink time slot N 2 Is U (U) 1 Target irregular uplink time slots of (a).
In some embodiments, as shown in fig. 5 in conjunction with fig. 4, in S403, the time slot resources of the irregular uplink time slot that the base station schedules the target to the terminal specifically include:
s501, when the number of the target irregular uplink time slots is a plurality of, the base station sorts the plurality of target irregular uplink time slots according to the order from small to large of the base noise values of the plurality of target irregular uplink time slots, so as to obtain a first sorting result.
The base noise value may be a total noise power of a Resource Block (RB) of each irregular uplink slot measured by the base station. The floor noise value for each non-regular uplink time slot may be the average of the non-regular uplink time slots in the plurality of frames.
Specifically, when the background noise value of the unconventional uplink time slot is lower, the noise interference suffered by the terminal when transmitting the service is smaller. Thus, the base station may obtain the floor noise value for each non-regular uplink slot before determining the maximum signal-to-noise ratio. Thus, when the number of the target irregular uplink time slots is a plurality of, the base station can sort the target irregular uplink time slots according to the order from the low noise value to the high noise value of the target irregular uplink time slots, so as to obtain a first sorting result.
Alternatively, the base station may re-measure the floor noise value of each irregular uplink slot after the first preset period of time has elapsed.
In combination with the above examplesAssuming that the background Noise value of the irregular uplink time slot N1 is Noise1, the irregular uplink time slot N 2 Is Noise2. Since Noise1 is greater than Noise2, the base station may determine that the first ranking result is (N 1 ，N 2 )。
S502, the base station orders a plurality of terminals corresponding to each target irregular uplink time slot according to the order from the small transmission power margin of the terminals to the large transmission power margin of the terminals so as to obtain a second ordering result corresponding to each target irregular uplink time slot.
Specifically, when the transmission power margin of the terminal is large, the stronger the interference of the noise resistance is when the terminal transmits the service in the irregular uplink time slot. Therefore, the base station can sequence the plurality of terminals corresponding to each target irregular uplink time slot according to the sequence from the small transmission power margin to the large transmission power margin of the terminals so as to obtain a second sequencing result corresponding to each irregular uplink time slot.
In connection with the above example, assume terminal U 1 Is T 1 Terminal U 2 Is T 2 . Due to T 2 Less than T 1 Then the irregular uplink time slot N 1 The corresponding second ranking result is (U 2 ，U 1 ). Non-regular uplink time slot N 2 The corresponding second ranking result is (U 1 )。
S503, the base station sequentially dispatches the time slot resources of the target irregular uplink time slot to a plurality of terminals according to the first sorting result and the second sorting result corresponding to the target irregular uplink time slot.
Specifically, the base station may select the target irregular uplink time slot from the first ordering result according to the order from the low noise floor value to the high noise floor value. The base station may then determine a second ranking result corresponding to the selected target irregular uplink time slot. And then, the base station can sequentially schedule the time slot resources of the selected target irregular uplink time slot for the terminal in the second sequencing result according to the second sequencing result corresponding to the selected target irregular uplink time slot.
Since the lower the background noise value of the irregular uplink time slot is, the less interference the terminal receives from the downlink time slots of surrounding cells when transmitting traffic in the irregular uplink time slot is. The lower the transmission power margin of the terminal is, the smaller the capability of the terminal to resist the interference of the downlink time slot when transmitting the service in the irregular uplink time slot is, so that the base station can schedule the irregular uplink time slot with lower bottom noise value to the terminal with lower transmission power margin through the first sequencing result and the second sequencing result, thereby enabling the terminal with lower noise resistance to transmit the service in the uplink time slot with lower noise influence and reducing the interference of the downlink time slot.
It should be noted that, when the base station schedules the time slot resource of the selected target uplink time slot for the target terminal in the second ordering result corresponding to the selected target irregular uplink time slot, and when the target terminal exists in the second ordering result corresponding to the unselected target irregular uplink time slot, the base station removes the target terminal in the second ordering result corresponding to the unselected target irregular uplink time slot, so as to avoid that the base station schedules multiple uplink time slots for the same terminal in the same scheduling period.
When the time slot resource of the target irregular uplink time slot is scheduled, and the time slot resource of the target irregular uplink time slot is not scheduled by the terminal in the second sequencing result corresponding to the target irregular uplink time slot, the base station schedules the time slot resource of the target irregular uplink time slot to the terminal in the next scheduling period.
Correspondingly, when the time slot resources of the target uplink time slot remain after the terminals in the second ordering result corresponding to the target irregular uplink time slot are all scheduled, other terminals do not meet the preset signal-to-noise ratio of the target irregular uplink time slot, so that the transmission quality of the transmission service of other terminals in the target irregular uplink time slot is poor. In this case, the base station no longer schedules the remaining slot resources of the target uplink slot to other terminals.
Alternatively, the terminals in the second ranking result may be represented by the international mobile equipment identity (International Mobile Equipment Identity, IMEI) of the terminal.
Alternatively, when the transmission power margins of the plurality of terminals are the same, the plurality of terminals may be ordered according to priorities of the plurality of terminals.
In combination with the above example, the base station may select the non-regular uplink time slot N according to the first ordering result 1 . The base station may then determine the irregular uplink time slot N 1 Corresponding second ranking result (U 2 ，U 1 ). Thereafter, the base station may send to the terminal U 2 Scheduling irregular uplink time slots N 1 Is allocated to the slot resources of the mobile station.
When the uplink time slot N is irregular 1 The time slot resources of (1) are scheduled, and the base station selects a second irregular uplink time slot N in a second ordering result 2 . The terminal may then determine the non-regular uplink time slot N 1 Corresponding second ranking result (U 1 ). Thereafter, the base station may send to the terminal U 1 Scheduling irregular uplink time slots N 2 Is allocated to the slot resources of the mobile station.
In some embodiments, the target frame further comprises a regular uplink slot; and presetting an uplink time slot of an uplink time slot position in a target frame by using a conventional uplink time slot. Referring to fig. 5, as shown in fig. 6, the method for reducing timeslot interference provided by the embodiment of the present application further includes:
S601, when the maximum signal-to-noise ratio of the terminal in the irregular uplink time slot is smaller than or equal to a preset signal-to-noise ratio, the base station schedules the time slot resource of the regular uplink time slot to the terminal.
Specifically, when the maximum signal-to-noise ratio of the terminal in the irregular uplink time slot is smaller than or equal to the preset signal-to-noise ratio, the base station can determine that the transmission quality of the terminal is lower when the terminal transmits the service in any irregular uplink time slot. Since the regular uplink time slot is an uplink time slot of the preset uplink time slot position, and the same uplink time slot position of the surrounding cells is also an uplink time slot, the regular uplink time slot is less interfered by the downlink time slots of the surrounding cells. In this way, the base station can schedule the slot resources of the regular uplink slots to the terminal.
It should be noted that, the base station may obtain the traffic to be transmitted of the terminal. When the traffic to be transmitted of the terminal is less than or equal to the second preset threshold, the base station can determine that the traffic to be transmitted of the terminal is less. The base station may then schedule the regular uplink time slots to the terminal. Correspondingly, when the traffic to be transmitted of the terminal is greater than a second preset threshold, the base station can acquire the maximum signal-to-noise ratio of the terminal in the irregular uplink time slot, so as to schedule the irregular uplink time slot to the terminal.
It should be understood that the base station first determines whether the traffic to be transmitted by the terminal is less than or equal to a second preset threshold, and then determines whether the maximum signal-to-noise ratio of the terminal in the irregular uplink time slot is greater than the preset signal-to-noise ratio.
The base station can determine that the terminal with the traffic volume to be transmitted smaller than or equal to the second preset threshold value and the terminal with the maximum signal-to-noise ratio smaller than or equal to the preset signal-to-noise ratio are both terminals corresponding to the conventional uplink time slot. When the base station schedules the regular uplink time slot to the terminal corresponding to the regular uplink time slot, the base station sequentially schedules the regular uplink time slot for the terminal according to the priority of the terminal.
In some embodiments, referring to fig. 6, as shown in fig. 7, the method for reducing timeslot interference provided in the embodiment of the present application further includes:
s701, when the time slot resources of the regular uplink time slot have residual resources, the base station sequentially dispatches the time slot resources of the regular uplink time slot to the terminal corresponding to the target irregular uplink time slot according to the sequence from the small transmission power margin of the terminal to the large transmission power margin of the terminal.
Specifically, after the base station schedules the timeslot resource of the regular uplink timeslot to the terminal, when the timeslot resource of the regular uplink timeslot has residual resources, the base station may determine all terminals corresponding to the target irregular uplink timeslot. And then, the base station sequentially dispatches the time slot resources of the remaining regular uplink time slots to the terminals corresponding to all the target irregular uplink time slots according to the sequence from the small transmission power margin of the terminals to the large transmission power margin of the terminals. Subsequently, after the terminal is scheduled by the remaining time slot resources of the regular uplink time slot, the base station removes all the terminals in the second ordering result because the terminal is already scheduled by the time slot resources of the uplink time slot, so as to avoid that the base station schedules a plurality of uplink time slots for the same terminal in the same scheduling period.
It should be noted that, after determining that the maximum signal-to-noise ratio of the terminal in the target irregular uplink timeslot is less than or equal to the preset signal-to-noise ratio and the traffic to be transmitted is less than or equal to the second preset threshold, the base station first schedules the regular uplink timeslot to the terminal corresponding to the regular uplink timeslot. Then, when the base station determines that there are remaining resources for the slot resources of the regular uplink slot, the base station schedules the remaining resources of the regular uplink slot to the target non-regular uplink slot. And subsequently, the base station schedules the irregular uplink time slot to the terminal corresponding to the target irregular uplink time slot.
In some embodiments, as shown in fig. 8 in conjunction with fig. 7, in S402 above, the base station determining the maximum signal-to-noise ratio of the terminal in the irregular uplink timeslot specifically includes:
s801, a base station acquires a background noise value of an irregular uplink time slot, a transmitting power allowance of a terminal and uplink signal receiving power sent by the terminal.
The uplink signal receiving power sent by the terminal may enable the total receiving power of all RBs sent by the terminal and received by the base station.
Specifically, before transmitting the service to the base station, the terminal may first send an uplink service request to the base station. Therefore, the terminal can transmit the transmission power margin of the terminal to the base station while transmitting the uplink service request. In addition, the base station may measure the floor noise value of each irregular uplink slot and the uplink signal reception power transmitted by the terminal.
Optionally, the terminal may also send the transmit power of the terminal to the base station.
S802, the base station determines the sum of the uplink signal receiving power sent by the terminal and the transmitting power allowance of the terminal as a first value.
Specifically, when the sum of the uplink signal receiving power sent by the terminal and the transmission power margin of the terminal is the maximum uplink signal receiving power that can be sent by the terminal. Therefore, the base station may determine the sum of the uplink signal reception power transmitted by the terminal and the transmission power margin of the terminal as the first value.
The uplink signal received power sent by the terminal is the power obtained by subtracting the uplink signal from the transmission power of the terminal and passing through the path loss. Therefore, the base station can determine that the sum of the transmission power of the terminal and the transmission power margin of the terminal is the second value, that is, the maximum transmission power that the terminal can achieve. And then, the base station can determine that the difference between the transmitting power of the terminal and the receiving power of the uplink signal sent by the terminal is a third value, namely the path loss of the uplink signal sent by the terminal in the transmission process. Subsequently, the base station can determine that the difference between the maximum transmission power which can be achieved by the terminal and the path loss of the uplink signal sent by the terminal in the transmission process is a first value, namely the maximum receiving power of the uplink signal which can be sent by the terminal.
S803, the base station determines the first value and the background noise value of the unconventional uplink time slot as the maximum signal-to-noise ratio of the terminal in the unconventional uplink time slot.
Specifically, the base station may determine the first value and the background noise value of the non-regular uplink time slot as the maximum signal-to-noise ratio of the terminal in the non-regular uplink time slot. Because the base noise values of the plurality of unconventional uplink time slots are different, and the maximum signal to noise ratios of the plurality of terminals are also different, the maximum signal to noise ratio of the same terminal in different unconventional uplink time slots is different, and the maximum signal to noise ratio of different terminals in the same unconventional uplink time slots is also different.
