Description
Technical Field

Background
The low-power-consumption large-connection scene is one of three service scenes of 5G communication, and the requirements of the mobile Internet of things are reflected. The main challenge facing the low power consumption and large connection scenario is that there are a large number of small data packet transmission services required for 100 ten thousand data connections per square kilometer. The small data packet transmission has the characteristics of small data packet, strong service burstiness and the like, and in order to quickly realize the small data packet service data transmission, potential solutions are to use scheduling-free transmission, novel multiple access transmission, adopt different scheduling schemes and other technical means. Among them, schedule-free transmission is a common solution. The scheduling-free transmission is a transmission mode of data transmission at any time, the data is immediately transmitted at the nearest time point after arriving, a terminal is not required to transmit a scheduling request and wait for the base station to authorize the scheduling, and the control overhead is reduced.
For scheduling-free transmission, because there is no dynamic scheduling information indication, multiple ues perform uplink transmission through the same unlicensed uplink resource, which increases the probability of collision on the same resource. When uplink transmission collision occurs to a plurality of user equipment, data cannot be uploaded, and at this time, data needs to be uploaded again. However, since the scheduling-free transmission is adopted in the data transmission scenario, after uplink transmission collision occurs in a plurality of user equipments, data is uploaded again through the unlicensed uplink resource, and collision may still occur, so that the problem of uplink transmission collision occurring in the user equipments during the scheduling-free transmission process cannot be effectively solved by the conventional collision retransmission solution.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention discloses a service scheduling processing method, which is applied to a base station for scheduling uplink service of a user terminal, and particularly, when the user terminal performs scheduling-free uplink data transmission through an authorization-free uplink physical resource and collides and performs data uploading again, the uplink service scheduling is performed on the collided user terminal so as to avoid the secondary collision.
Referring to fig. 1, in a scheduling-free uplink data transmission scenario, especially in a scheduling-free uplink data transmission scenario with a low power consumption and a large connection, both user terminals UE1 and UE2 … UEn perform uplink data transmission through a set grant-free uplink physical resource. Because the unlicensed uplink physical resource is limited, when a plurality of user terminals uplink-transmit data through the unlicensed uplink physical resource at the same time, collision may occur greatly, and the user terminals that collide cannot realize uplink data transmission.
In the conventional collision solution, when a collision occurs in uplink data transmission of a ue, the collided ue is caused to perform uplink data transmission again. In the scheduling-free uplink data transmission scenario, due to the large number of the user terminals, when the user terminal having the collision performs uplink data transmission again through the authorization-free uplink physical resource, the user terminal still may collide again, and the collision problem cannot be effectively solved.
The service scheduling processing method disclosed by the embodiment of the invention is a service scheduling processing method which is provided for avoiding the situation that the user terminal in the scheduling-free uplink data transmission scene collides again when the uplink data transmission is carried out again after the collision.
Referring to fig. 2, a method for scheduling and processing a service according to an embodiment of the present invention includes:
when a first user terminal and a second user terminal upload data through an authorization-free physical resource and collide with each other, step S201 is executed, the first user terminal or the second user terminal is scheduled to upload data again through a reserved authorized physical resource, and/or the first user terminal or the second user terminal is scheduled to upload data again after a time delay is set.
Specifically, the first user terminal and the second user terminal are used to represent any two user terminals that collide in a scheduling-free uplink data transmission scenario. In the above scheduling-free uplink data transmission scenario, there are a large number of ues, and when the ues perform uplink data transmission collision, uplink data transmission collision must occur between at least two ues. When a plurality of ues collide in uplink data transmission, in order to avoid the collision again when the plurality of ues perform uplink data transmission again, it is necessary to schedule uplink data transmission of at least one of the ues to reduce the possibility of collision again.
In the embodiment of the present invention, the first user terminal and the second user terminal are taken as an example, and a service scheduling processing method when two user terminals collide in uplink data transmission is described.
In the embodiment of the present invention, when the first user terminal and the second user terminal collide with each other by uploading data through the set authorization-free physical resource, the first user terminal or the second user terminal is scheduled to upload data again through the reserved authorized physical resource, or the first user terminal or the second user terminal is scheduled to upload data again after delaying for the set time length.
Specifically, when two user terminals (i.e., a first user terminal and a second user terminal) collide in uplink data transmission, the embodiment of the present invention schedules one of the user terminals (the first user terminal or the second user terminal) to no longer transmit data uplink through the original authorization-free physical resource, but schedules the user terminal to upload data again through the reserved authorized physical resource. Correspondingly, for the user terminal which is not scheduled, the data can be uploaded again through the original authorization-free physical resource after the uplink data transmission collision occurs. Through the scheduling, the two user terminals which have uplink data transmission collision are enabled to respectively perform uplink data transmission again through different physical resources, and uplink data transmission collision of the two user terminals can be effectively avoided.
For example, as shown in fig. 3, it is assumed that UE1 and UE2 collide at time t1 when data is simultaneously transmitted uplink via unlicensed physical resource f 4. According to the technical scheme of the embodiment of the invention, when the UE1 and the UE2 upload data next time, the UE1 is scheduled to upload the data again through the authorized physical resource f1, and the UE2 uploads the data again through the unauthorized physical resource f 4. Since the scheduled UE1 and UE2 respectively perform uplink data transmission through the f1 and f4 physical resources, uplink data transmission collision can be avoided.
Or, when two user terminals (i.e., the first user terminal and the second user terminal) collide with each other in uplink data transmission, the base station schedules one of the user terminals (the first user terminal or the second user terminal) for a delay set time period, and then re-uploads the data. Correspondingly, for the user terminal which is not scheduled, the data can be immediately uploaded again through the original authorization-free physical resource after the uplink data transmission collision occurs.
For example, as shown in fig. 3, it is assumed that UE1 and UE2 collide at time t1 when they simultaneously transmit data uplink via unlicensed physical resource f 4. According to the technical scheme of the embodiment of the invention, the UE1 and the UE2 need to be scheduled when data is uploaded next time, specifically, the UE1 is scheduled to delay the time of setting duration at the time of next uploading (namely, the time of t 2), for example, at the time of t3, the data is re-uplinked through the authorization-free physical resource f4, and the UE2 immediately re-uplinks the data through the authorization-free physical resource f4 at the time of next uploading, namely, at the time of t 2. Since the scheduled UE1 and UE2 respectively perform uplink data transmission through the unlicensed physical resource at times t2 and t3, uplink data transmission collision can be avoided from occurring again.
Further, when the base station schedules one of the user terminals (the first user terminal or the second user terminal) to upload data again after delaying the set time, the user terminal may be specifically scheduled to upload data again through the original authorization-free physical resource, or may be scheduled to upload data again through the reserved authorized physical resource, that is, after the base station schedules the UE1 to set time for delaying the time, the UE1 re-uploads the data through the authorized physical resource f1 at time t 3.
It can be understood that, when the scheduling, by the base station, of one of the user terminals (the first user terminal or the second user terminal) to re-upload data with the delay setting time is specifically to schedule the user terminal to re-upload data through the reserved authorized physical resource, actually, the scheduling of the first user terminal or the second user terminal to re-upload data through the reserved authorized physical resource and the scheduling of the first user terminal or the second user terminal to re-upload data after the delay setting time are implemented at the same time. That is, when the first user terminal and the second user terminal collide in uplink data transmission, one of the user terminals (the first user terminal or the second user terminal) is scheduled to re-upload data through the reserved authorized physical resource, and the user terminal is scheduled to re-upload data with a delay set time length. For example, as shown in fig. 3, it is assumed that UE1 and UE2 collide at time t1 when they simultaneously transmit data uplink via unlicensed physical resource f 4. According to the technical scheme of the embodiment of the invention, immediately scheduling UE1 to delay and set time length in next uploading, and then re-uplink transmitting data through the authorized physical resource f1 at the time of t3, and UE2 re-uplink transmitting data through the authorization-free physical resource f4 at the time of next uploading, namely at the time of t 2.
Through the scheduling, the two collided user terminals can be ensured to occupy different physical resources at different moments to perform uplink data transmission again, so that the two user terminals are further prevented from colliding again. It should be noted that, when the first user terminal or the second user terminal is scheduled to re-upload data through the reserved authorized physical resource and the first user terminal or the second user terminal is scheduled to re-upload data after delaying for a set time, it is guaranteed that the first user terminal or the second user terminal is scheduled for the same user terminal.
Through the above, one of the two user terminals scheduled to have uplink data transmission collision delays for a set time and uploads data again through the non-authorized physical resource or the reserved authorized physical resource, so that the two user terminals having collision can be ensured to occupy the physical resource at different moments, and uplink data transmission collision can be avoided.
The above-mentioned license-free physical resource and the license physical resource both belong to physical resources that can be used for data transmission. In order to occupy user terminals in different types of communication scenes, the embodiment of the invention sets the base station to classify the available physical resources into authorization-free physical resources and authorization physical resources.
The above-mentioned non-authorized physical resource is randomly occupied by the user terminal in the scheduling-free data uplink transmission scene, and the above-mentioned authorized physical resource is occupied by the base station for the user terminal in other communication scenes.
Furthermore, in order to facilitate the scheduling of the user terminal to occupy the authorized physical resource when the uplink data transmission collision occurs in the user terminal which performs the uplink data transmission in the authorization-free physical resource by the base station, the invention sets the base station to reserve a part of the authorized physical resource, which is specially used for being allocated to the user terminal which generates the collision to occupy. It is to be understood that the reserved authorized physical resources refer to a part of authorized physical resources reserved by the base station from the divided authorized physical resources.
It should be noted that, in the embodiment of the present invention, the idea of the service scheduling processing method disclosed in the embodiment of the present invention is described only in the service scheduling processing procedure when the first user terminal and the second user terminal collide with each other in uplink data transmission. However, the embodiment of the present invention is not limited to be applicable to a scenario where two ues collide in uplink data transmission. When a plurality of user terminals have uplink data transmission collision, the technical scheme disclosed by the embodiment of the invention can be referred to, and uplink service scheduling processing is carried out on the plurality of user terminals, so that the plurality of user terminals are prevented from having uplink data transmission collision again. For example, the plurality of collided ues may be scheduled to delay 5ms,10ms,20ms,30ms,40ms … respectively and then upload the data again, or may be scheduled to upload the data again through the reserved authorized resource block group RBG1, RBG2, RBG3 … respectively.
As can be seen from the above description, in the service scheduling processing method disclosed in the embodiment of the present invention, when a collision occurs between a first user terminal and a second user terminal uploading data through an authorization-free physical resource, the first user terminal or the second user terminal is scheduled to upload data again through a reserved authorized physical resource, and/or the first user terminal or the second user terminal is scheduled to upload data again after a time delay is set. Through the scheduling processing, different user terminals which collide can perform uplink data transmission again through different time frequency resources, so that uplink data transmission collision can be effectively avoided, and the problem that the user equipment generates uplink transmission collision in the scheduling-free transmission process is effectively solved.
Optionally, in another embodiment of the present invention, a specific processing procedure for scheduling the first user terminal or the second user terminal to upload data through the reserved authorized physical resource is further disclosed.
Referring to fig. 4, the scheduling of the first user terminal or the second user terminal to upload data again through the reserved authorized physical resource disclosed in the embodiment of the present invention includes:
s401, comparing the magnitude relation of the index values of the modulation and coding strategies of the first user terminal and the second user terminal;
specifically, for the ue having uplink data transmission collision, when one of the ues is scheduled to re-upload data via the reserved authorized physical resource, it needs to determine which ue should be scheduled to re-upload data via the reserved authorized physical resource.
In the embodiment of the invention, the size of the index value of the modulation and coding strategy of the collided user terminal is set to determine which user terminal should be scheduled to upload data again through the reserved authorized physical resource.
The rate configuration in LTE is implemented by an index value of a Modulation and Coding Scheme (MCS). The MCS forms a rate table with the MCS index values as rows and the columns of the table as the factors that affect the communication rate concerned. Therefore, each MCS index value actually corresponds to a physical transmission rate under a set of parameters.
The larger the index value of the MCS of the user terminal is, the higher the physical transmission rate of the user terminal is, and conversely, the smaller the index value of the MCS of the user terminal is, the lower the physical transmission rate of the user terminal is.
If the index value of the modulation and coding strategy of the first user terminal is larger, executing step S402, scheduling the first user terminal to upload data again through the reserved authorized physical resource;
and if the index value of the modulation and coding strategy of the second user terminal is larger, executing step S403, and scheduling the second user terminal to upload data again through the reserved authorized physical resource.
Specifically, in the embodiment of the present invention, the user terminal with a large index value of the MCS in the user terminals where uplink data transmission collision occurs is set to be selectively scheduled to upload data again through the reserved authorized physical resource.
By comparing the index values of the MCS of the first user terminal and the second user terminal, if the index value of the MCS of the first user terminal is larger, the first user terminal is scheduled to upload data again through the reserved authorized physical resource; and if the index value of the MCS of the second user terminal is larger, scheduling the second user terminal to upload data again through the reserved authorized physical resource.
By setting the user terminal with a larger index value of the scheduling MCS, that is, the user terminal with a higher physical transmission rate uploads data again through the reserved authorized physical resource, it can be ensured that the user terminal uploads data again through the reserved authorized physical resource quickly, so that the occupied time of the reserved authorized physical resource is reduced, and other collided user terminals occupy the reserved authorized physical resource to upload data again.
Optionally, in another embodiment of the present invention, a specific processing procedure for scheduling the first user terminal or the second user terminal to upload data again through the reserved authorized physical resource is further disclosed.
In this embodiment of the present invention, the scheduling the first user terminal or the second user terminal to upload data again through the reserved authorized physical resource specifically includes:
and allocating time-frequency resources in the reserved authorized physical resources to the first user terminal or the second user terminal, so that the first user terminal or the second user terminal can upload data again through the divided time-frequency resources.
Specifically, the first user terminal or the second user terminal is scheduled to re-upload data through the reserved authorized physical resources, and the method is mainly used for allocating time-frequency resources in the reserved authorized physical resources to the first user terminal or the second user terminal, so that the first user terminal or the second user terminal re-uploads data through the divided time-frequency resources.
And the base station distributes the time-frequency resource information for the first user terminal or the second user terminal to the first user terminal or the second user terminal through a control channel instruction or an RRC signaling.

The service scheduling processing device disclosed by the embodiment of the invention is applied to a base station and can monitor whether the user terminal which is transmitted in an uplink mode through the authorization-free physical resource is collided or not. When collision of the first user terminal and the second user terminal through the data uploading of the authorization-free physical resources is monitored, the first user terminal or the second user terminal is scheduled to upload data again through the reserved authorized physical resources, and/or the first user terminal or the second user terminal is scheduled to upload data again after time delay is set for a time length. Through the scheduling processing, different user terminals which are collided can perform uplink data transmission again through different time frequency resources, so that uplink data transmission collision can be effectively avoided, and the problem of uplink transmission collision of user equipment in the scheduling-free transmission process is effectively solved.
