Background
In the current scheduling scheme of the base station, the uplink and downlink services of the terminal are distinguished for the scheduling of the terminal and are respectively and independently scheduled. Specifically, when the base station schedules the user, the base station may determine a scheduling result (such as a modulation and coding scheme, a frequency domain scheduling position, and the like) of scheduling the uplink or downlink unidirectional link according to the channel quality/signal-to-interference-and-noise ratio of the uplink or downlink unidirectional link of the scheduled user, so as to maximize the spectral efficiency of the system. For example, uplink service scheduling is performed, and the base station refers to the channel quality/signal-to-interference-and-noise ratio of the uplink; and performing downlink service scheduling, wherein the base station refers to the channel quality/signal-to-interference-and-noise ratio of a downlink.

Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
In various embodiments of the present invention, it should be understood that the sequence numbers of the following processes do not mean the execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
In addition, the terms "system" and "network" are often used interchangeably herein.
In the embodiments provided herein, it should be understood that "B corresponding to a" means that B is associated with a from which B can be determined. It should also be understood that determining B from a does not mean determining B from a alone, but may be determined from a and/or other information.
As shown in fig. 1, a scheduling method according to an embodiment of the present invention is executed by a network device, and includes:
step 101, allocating or adjusting at least one of service scheduling bandwidth, initial frequency point position of service scheduling and termination frequency point position of service scheduling of one or more service transmissions of a first user equipment;
at least one of the allocated or adjusted service scheduling bandwidth, the start frequency point position of the service scheduling and the stop frequency point position of the service scheduling is located in a first frequency band, and the first frequency band has no intermodulation interference, or the intermodulation interference degree of the first frequency band is smaller than a preset threshold;
the service transmission refers to control signaling and/or service data, and the service transmission comprises uplink transmission and/or downlink transmission of services.
According to the above steps, the method of the embodiment of the present invention allocates or adjusts at least one of a service scheduling bandwidth, a start frequency point position of service scheduling, and a stop frequency point position of service scheduling for one or more service transmissions of a first user, wherein at least one of the allocated or adjusted service scheduling bandwidth, the start frequency point position of service scheduling, and the stop frequency point position of service scheduling is located in a first frequency band, and the first frequency band has no intermodulation interference, or the intermodulation interference degree of the first frequency band is smaller than a preset threshold, so that the service transmission of the first user equipment can effectively avoid the intermodulation interference.
At least one of service scheduling bandwidth, starting frequency point position of service scheduling and ending frequency point position of service scheduling of one or more service transmissions is allocated, and the method is suitable for a scene of first resource scheduling of one or more service transmissions. And at least one of the service scheduling bandwidth of one or more service transmissions, the initial frequency point position of the service scheduling and the termination frequency point position of the service scheduling is adjusted, so that the method is suitable for the scene that the first user equipment generates intermodulation interference.
It should be appreciated that, for the existence of intermodulation interference of the user equipment, the scheduling information of the user equipment can be determined by the base station. For example, the uplink bandwidth supported by the base station a ranges from f1 to f2 (e.g., 703MHz for f1 and 733MHz for f2), and the downlink bandwidth ranges from f3 to f4 (e.g., 758MHz for f3 and 788MHz for f 4). When the terminal 1 is scheduled by the base station a to transmit an uplink signal within a bandwidth range from f5 to f6 (e.g., f5 is f1, f6 is f2), an initial frequency point position f7 where third-order intermodulation interference occurs is 2 f5-f6 is 2 f1-f2 is 673MHz, and a termination frequency point position f8 is 2 f6-f5 is 2 f2-f1 is 763MHz, so that if the bandwidth where the terminal 1 is scheduled by the base station a to receive a downlink signal at least includes a 758M-763M band, the uplink signal transmission of the terminal 1 affects the sensitivity of downlink reception of the terminal, and intermodulation interference occurs. Of course, for scheduling of the terminal, the reception of the downlink signal may also affect the transmission of the uplink signal, and is not described herein again.
In this embodiment, optionally, step 101 includes:
and allocating or adjusting at least one of service scheduling bandwidth, start frequency point position of service scheduling and stop frequency point position of service scheduling of one or more service transmissions of the first user equipment according to the service quality requirement.
Therefore, at least one of the allocated or adjusted service scheduling bandwidth, the start frequency point position of the service scheduling and the stop frequency point position of the service scheduling can be suitable for the transmission requirement of one or more service transmissions while avoiding intermodulation interference.
Optionally, the service quality requirement includes at least one of a service rate, a service delay, a service priority, and a service reliability.
As such, scheduling information for one or more traffic transmissions of the first user equipment may be assigned or adjusted based on at least one of traffic rate, traffic delay, traffic priority, and traffic reliability. Specifically, the scheduling information includes at least one of a service scheduling bandwidth, a start frequency point position of the service scheduling, and a stop frequency point position of the service scheduling. Thus, the assigned or adjusted scheduling information will enable higher quality transmissions.
Optionally, in this embodiment, the allocating or adjusting at least one of a service scheduling bandwidth of one or more services of the first user equipment, a start frequency point position of service scheduling, and a stop frequency point position of service scheduling according to a service quality requirement includes:
and under the condition that the bandwidth of the first frequency band meets the service quality requirement of first service transmission of the first user equipment, allocating or adjusting the initial frequency point position and/or the termination frequency point position of service scheduling corresponding to the first service transmission to the initial frequency point position and/or the termination frequency point position of the first frequency band, or allocating or adjusting the initial frequency point position and/or the termination frequency point position to the frequency point interval covered by the first frequency band.
Here, in the case that the bandwidth of the first frequency band satisfies the service quality requirement of the first service transmission of the first user equipment, the start frequency point position of the corresponding service schedule of the first service transmission is allocated or adjusted to the start frequency point position of the first frequency band, and/or the end frequency point position of the corresponding service schedule of the first service transmission is allocated or adjusted to the end frequency point position of the first frequency band. Or, the position of the start frequency point and/or the position of the end frequency point of the corresponding service schedule of the first service transmission may be allocated or adjusted to be within the frequency point interval covered by the first frequency band.
For example, continuing with the base station a, in a certain scheduling timeslot, the base station a performs downlink scheduling on downlink transmission of the terminal 2 (first user equipment) in the scheduling queue, where the downlink scheduling is a 30MHz bandwidth of 758M to 788M, and the terminal 2 has intermodulation interference. For the downlink scheduling of the terminal 2, the frequency band without intermodulation interference (i.e. frequency band 1) is 703M to 730.5M, and the frequency band 1 meets the quality requirement of the uplink transmission (first service transmission) service of the terminal 2, the uplink scheduling corresponding to the uplink transmission of the terminal 2 may be allocated or adjusted, the position of the start frequency point of the uplink scheduling is allocated or adjusted to 703MHz, and/or the position of the stop frequency point of the uplink scheduling is allocated or adjusted to 730.5 MHz. Of course, the start frequency point position and/or the end frequency point position of the uplink scheduling corresponding to the terminal 2 row transmission may also be other frequency points in 703M to 730.5M.
And allocating or adjusting the service scheduling corresponding to the first service transmission, wherein the bandwidth of the allocated or adjusted service scheduling meets the service quality requirement of the first service transmission of the first user equipment.
In addition, in view of a situation that the bandwidth of the first frequency band does not meet the service quality requirement of the first service transmission of the first user equipment, on one hand, optionally, in this embodiment, the allocating or adjusting at least one of the service scheduling bandwidth, the start frequency point position of the service scheduling, and the end frequency point position of the service scheduling of one or more services of the first user equipment according to the service quality requirement includes:
and under the condition that the bandwidth of the first frequency band does not meet the service quality requirement of first service transmission of the first user equipment, allocating or adjusting the position of a start frequency point and/or the position of a stop frequency point of service scheduling corresponding to the first service transmission to a second frequency band, wherein the second frequency band is at least partially overlapped with a frequency point interval covered by the first frequency band.
Here, for a case that the bandwidth of the first frequency band does not meet the service quality requirement of the first service transmission of the first user equipment, the start frequency point position and/or the end frequency point position of the corresponding service schedule of the first service transmission may be allocated or adjusted to a second frequency band at least partially overlapping with the frequency point interval covered by the first frequency band.
For example, continuing with the base station a, in a certain scheduling time slot, the base station a performs downlink scheduling on downlink transmission of the terminal 3 (first user equipment) in the scheduling queue, and performs uplink scheduling on uplink transmission, but intermodulation interference exists in uplink and downlink scheduling of the terminal 3. Assuming that, for the downlink scheduling 758M to 788M of the terminal 3, the frequency bands (i.e., frequency bands 1)703M to 730.5M without intermodulation interference do not satisfy the requirement of the quality of the uplink transmission (first service transmission) service of the terminal 3, the uplink scheduling corresponding to the uplink transmission of the terminal 3 may be adjusted, and the start frequency point position and/or the end frequency point position of the uplink scheduling are allocated or adjusted to a frequency band 2, where the frequency band 2 and the frequency band interval covered by the frequency band 1 are at least partially overlapped.
Certainly, the service scheduling corresponding to the first service transmission is allocated or adjusted, and the bandwidth of the allocated or adjusted service scheduling meets the service quality requirement of the first service transmission of the first user equipment.
On the other hand, optionally, the allocating or adjusting at least one of a service scheduling bandwidth of one or more services of the first user equipment, a start frequency point position of service scheduling, and a stop frequency point position of service scheduling according to the service quality requirement includes:
reducing the service scheduling bandwidth of the first service transmission of the first user equipment and/or allocating or adjusting the initial frequency point position and/or the termination frequency point position of the service scheduling corresponding to the first service transmission under the condition that the bandwidth of the first frequency band does not meet the service quality requirement of the second service transmission of the first user equipment;
wherein the priority of the second traffic transmission is higher than or equal to the priority of the first traffic transmission.
Here, for the case that the bandwidth of the first frequency band does not satisfy the service quality requirement of the second service transmission of the first user equipment, the corresponding service schedule of the first service transmission with the priority lower than that of the second service transmission may be allocated or adjusted. Specifically, the service scheduling bandwidth of the first service transmission may be reduced, or the start frequency point position and/or the end frequency point position of the service scheduling may be allocated or adjusted, and at this time, after the service scheduling of the first service transmission is allocated or adjusted, at least one of the service scheduling bandwidth of the second service transmission, the start frequency point position of the service scheduling, and the end frequency point position of the service scheduling is located in the first frequency band.
For example, continuing with the base station a, in a certain scheduling time slot, the base station a performs downlink scheduling on downlink transmission and uplink scheduling on uplink transmission of the terminal 4 (first user equipment) in the scheduling queue, but intermodulation interference exists in the uplink and downlink scheduling of the terminal 4. If the priority of the downlink transmission (second service transmission) of the terminal 4 is higher than or equal to the priority of the uplink transmission (first service transmission), and for the uplink scheduling of the terminal 4, the frequency band without intermodulation interference does not meet the quality requirement of the downlink transmission service of the terminal 4, the uplink scheduling corresponding to the uplink transmission of the terminal 4 may be allocated or adjusted, so as to reduce the bandwidth of the uplink scheduling, or the position of the start frequency point and/or the position of the stop frequency point of the uplink scheduling may be allocated or adjusted.
The allocation or adjustment of the service schedule corresponding to the first service transmission may preferably enable the first frequency band to meet a service quality requirement of the second service transmission of the first user equipment.
In this embodiment, optionally, the method further includes:
and when the priority of the third service transmission of the second user equipment is higher than or equal to the priority of the first service transmission of the first user equipment and the third service transmission needs to occupy at least part of the first frequency band, reducing the service scheduling bandwidth of the first service transmission of the first user equipment and/or allocating or adjusting the start frequency point position and/or the stop frequency point position of the service scheduling corresponding to the first service transmission.
Here, for a case that the priority of the third service transmission of the second user equipment is higher than or equal to the priority of the first service transmission of the first user equipment, and the third service transmission needs to occupy at least part of the first frequency band, since at least part of the first frequency band is preferentially called for the third service transmission, the service scheduling bandwidth of the first service transmission of the first user equipment may be reduced, and/or the start frequency point position and/or the end frequency point position of the service scheduling corresponding to the first service transmission may be allocated or adjusted, so that the first service transmission may only use part of the bandwidth on the first frequency band that is not occupied by the third service transmission. Preferably, by reducing the service scheduling bandwidth of the first service transmission of the first user equipment, and/or allocating or adjusting the start frequency point position and/or the end frequency point position of the service scheduling corresponding to the first service transmission, a part of the bandwidth not occupied by the third service transmission on the first frequency band may be used as the service scheduling bandwidth of the first service transmission. Of course, if the service scheduling bandwidth of the first service transmission is greater than a part of the bandwidth, which is not occupied by the third service transmission, of the first frequency band, the service scheduling bandwidth of the first service transmission is not adjusted, and the start frequency point position and/or the end frequency point position of the service scheduling corresponding to the first service transmission may also be allocated or adjusted outside the first frequency band.
For example, continuing with the base station a described above, in a certain scheduling time slot, the base station a schedules uplink and downlink transmissions of the terminal 5 (first user equipment) and the terminal 6 (second user equipment) in the scheduling queue, but intermodulation interference exists in the uplink and downlink scheduling of the terminal 5. Assuming that the priority of the uplink transmission (third service transmission) of the terminal 6 is higher than or equal to the priority of the uplink transmission (first service transmission) of the terminal 5, and for the downlink scheduling 758M to 788M of the terminal 5, the frequency band without intermodulation interference (i.e., the frequency band 1) is 703M to 730.5M, but since the bandwidth required for the uplink transmission of the terminal 6 is 23M, the frequency band 710M to 733M is preferentially allocated to the uplink transmission of the terminal 6, so that the uplink transmission of the terminal 6 occupies the part of the frequency band 1, the uplink scheduling corresponding to the uplink transmission of the terminal 5 can be adjusted to reduce the bandwidth of the uplink scheduling to 7M, and the uplink transmission of the terminal 5 is performed only by using the frequency band 703M to 710M, which is the remaining part of the frequency band 1.
Optionally, the allocating or adjusting at least one of a service scheduling bandwidth of one or more service transmissions of the first user equipment, a start frequency point position of service scheduling, and a stop frequency point position of service scheduling includes:
and under the condition that the priority of the first service transmission of the first user equipment is higher than or equal to the priority of the fourth service transmission of the third user equipment, allocating or adjusting the starting frequency point position and/or the ending frequency point position of the service scheduling corresponding to the first service transmission to the starting frequency point position and/or the ending frequency point position of the first frequency band, or allocating or adjusting the starting frequency point position and/or the ending frequency point position of the first frequency band to be within the frequency point interval covered by the first frequency band.
That is to say, for the service transmissions of two users, when the service priority of the service transmission (first service transmission) of the first user equipment is higher than that of the service transmission (fourth service transmission) of the third user equipment, the first service transmission is scheduled preferentially compared with the fourth service transmission, so that the start frequency point position and/or the end frequency point position of the service scheduling corresponding to the first service transmission is allocated or adjusted to the start frequency point position and/or the end frequency point position of the first frequency band, or allocated or adjusted to the frequency point interval covered by the first frequency band.
Of course, the allocation or adjustment of the start frequency point position and/or the end frequency point position of the corresponding service scheduling for the first service transmission may also be performed in combination with the service quality requirement, as described above, which is not described herein again.
For example, continuing with the base station a described above, in a certain scheduling time slot, the base station a schedules uplink and downlink transmissions of the terminal 7 (first user equipment) and the terminal 8 (second user equipment) in the scheduling queue, but intermodulation interference exists in the uplink and downlink scheduling of the terminal 7. Assuming that the priority of the uplink transmission (first service transmission) of the terminal 7 is higher than or equal to the priority of the uplink transmission (fourth service transmission) of the terminal 8, for the downlink scheduling 758M to 788M of the terminal 7, the frequency band without intermodulation interference (i.e., frequency band 1) is 703M to 730.5M, the uplink transmission of the terminal 7 is preferentially scheduled on the frequency band 1, and then the unoccupied part of the first service transmission in the frequency band 1 and/or the part outside the frequency band 1 of the uplink transmission scheduling of the terminal 8 are considered.
In this embodiment, considering that there are often a plurality of terminals scheduled by the network device, optionally, after allocating or adjusting at least one of a service scheduling bandwidth, a start frequency point position of service scheduling, and a termination frequency point position of service scheduling of one or more services of the first user equipment according to the service quality requirement, the method further includes:
and allocating or adjusting at least one of the service scheduling bandwidth, the start frequency point position of the service scheduling and the stop frequency point position of the service scheduling of other user equipment to be scheduled according to the allocation or adjustment of at least one of the service scheduling bandwidth, the start frequency point position of the service scheduling and the stop frequency point position of the service scheduling of one or more services of the first user equipment.
In this way, after allocating or adjusting at least one of the service scheduling bandwidth, the start frequency point position of the service scheduling and the end frequency point position of the service scheduling of one or more services of the first user equipment, for other user equipment to be scheduled, the allocation or adjustment may be further performed based on the allocation or adjustment of the service scheduling of the first user equipment, specifically, at least one of the service scheduling bandwidth, the start frequency point position of the service scheduling and the end frequency point position of the service scheduling of the other user equipment may be allocated or adjusted, so as to avoid interference between subsequent transmissions of each user equipment.
Here, the other user equipments to be scheduled may be user equipments other than the first user equipment in the scheduling queue.
In this embodiment, optionally, the preset threshold includes at least one of the following:
a first value;
the sum of the background noise and the second value;
and adjusting the absolute difference value of the intermodulation interference degree of the front frequency band and the third value.
Therefore, the preset threshold may be an absolute value, i.e., a first value. The preset threshold may also be a relative value, that is, the preset threshold is the sum of the background noise and a second value, that is, the intermodulation interference degree of the first frequency band is not higher than the second value of the background noise; or, the preset threshold is an absolute difference between the intermodulation interference degree of the frequency band before adjustment and the third value, that is, the intermodulation interference degree of the first frequency band is reduced by the third value compared with the intermodulation interference degree of the frequency band before adjustment. Here, the first value, the second value, and the third value are predefined or adjusted in conjunction with a transmission environment.
It should be appreciated that the first user device in this embodiment is preferably an edge user of the network device.
