Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for uplink pre-scheduling.
Background
With the development of communication technology, in order to transmit uplink data, the base station mainly adopts the following method for resource allocation to the terminal:
a terminal sends Control information including a Scheduling Request (SR) to a base station through a Physical Uplink Control CHannel (PUCCH), then the base station sends an Uplink Scheduling grant (UL grant) to the terminal according to the received SR, and allocates a small amount of resources to the terminal, and further, after the terminal reports a Buffer Status Report (BSR) to the base station, the base station allocates resources to the terminal according to a Sounding reference signal (Sounding RS, SRs) of the terminal and its own existing resources, and then the terminal performs Physical Uplink Shared CHannel (PUSCH) resource allocation.
However, with this method, when the terminal performs uplink data transmission each time, if there is no PUSCH resource, it needs to apply for SR, obviously, this will increase the time delay of uplink data, and affect the user rate perception.
In the prior art, in order to reduce uplink data delay and improve user rate perception, a base station adopts an uplink pre-scheduling mechanism to perform PUSCH resource scheduling. The uplink pre-scheduling mechanism is a mechanism that a terminal does not need to perform SR application, PUSCH resources are periodically allocated to the terminal after uplink or downlink real data is triggered, so that SR application triggered when uplink data arrives is reduced, and Interference over Thermal (IoT) is reduced by limiting the number of total Physical Resource Blocks (PRBs) pre-scheduled by a single subframe.
However, in this way, since the terminal with a poor channel environment has higher transmission power, this may improve IoT of the cell and Key Performance Indicators (KPIs) of the network, and further, the terminal with a poor channel environment may cause pre-scheduled data retransmission, and since the scheduling priority of the retransmitted data is higher than that of newly transmitted data, this may affect data transmission of other terminals, and reduce transmission efficiency of other terminals.

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.
In order to reduce IoT of a cell, improve KPI of a network, avoid data retransmission, improve transmission efficiency of each terminal and optimize resource allocation when uplink pre-scheduling is performed, in the embodiment of the invention, an uplink pre-scheduling method is designed.
Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Referring to fig. 1, in the embodiment of the present invention, a specific process of uplink pre-scheduling is as follows:
step 100: and the base station monitors the transmission state information of the terminal to obtain a monitoring result.
In practical application, the base station monitors the transmission state information of each terminal, and obtains the monitoring result of each terminal respectively.
The transmission state information represents a data transmission state between the terminal and the local, that is, whether data transmission is performed between the terminal and the local.
For example, the base station monitors the transmission state of the terminal, and obtains a monitoring result representing that no data transmission occurs between the local terminal and the terminal when determining that no data transmission occurs between the terminal and the local terminal.
For another example, the base station monitors the transmission state of the terminal, and when determining that the base station is sending data to the terminal, obtains a monitoring result representing that the data is sent to the terminal locally.
Therefore, the base station can determine whether data transmission is performed between the terminal and the local area or not through a monitoring result obtained by monitoring the transmission state information of the terminal.
Step 110: and the base station determines the terminal with the transmission state information meeting the preset triggering condition according to the monitoring result.
In practical application, the base station determines that the transmission state information of the terminal meets the preset trigger condition according to the monitoring result, and may adopt, but is not limited to, the following several ways:
the first mode is as follows: and when the base station determines that the terminal transmission state information represents the data sent by the local receiving terminal according to the monitoring result, determining that the terminal transmission state information meets the preset triggering condition.
The second way is: and when the base station determines that the terminal transmission state information represents that data is locally sent to the terminal according to the monitoring result, determining that the transmission state information of the terminal meets a preset trigger condition.
Therefore, the base station can trigger a subsequent uplink pre-scheduling mechanism when determining that data transmission is performed between the local station and the terminal through the monitoring result, thereby reducing the SR application process triggered when the terminal needs to allocate resources, reducing the time delay of uplink data and improving the efficiency of the system.
Further, the base station performs priority ranking on each terminal of which the transmission state information meets the preset triggering condition, so that the base station can sequentially perform subsequent judgment and scheduling processing on each terminal according to the priority ranking of each terminal in subsequent steps.
Step 120: and the base station acquires the current signal comparison result of the terminal.
In practical applications, when step 120 is executed, the signal comparison result can be obtained in, but not limited to, the following two ways:
the first mode is as follows: the method comprises the steps of obtaining a signal of a cell where a terminal is located and a signal of an adjacent cell based on measurement information reported by the terminal, comparing the signal of the cell where the terminal is located with the signal of the adjacent cell according to a preset mode to obtain a comparison result, and taking the comparison result as a current signal comparison result of the terminal.
The second way is: the method comprises the steps of obtaining a signal of a cell where a terminal is located, a signal of an adjacent cell and the current frequency spectrum efficiency of the terminal based on measurement information reported by the terminal, comparing the signal of the cell where the terminal is located with the signal of the adjacent cell according to a preset mode to obtain a comparison result, and taking the comparison result and the current frequency spectrum efficiency of the terminal as the current signal comparison result of the terminal.
And the signal comparison result represents a result obtained after the signal of the cell where the terminal is located and the signal of the adjacent cell are compared in a preset mode.
And when the base station determines that the signal intensity of the cell where the terminal is positioned is higher than that of the adjacent cell, setting the scheduling state corresponding to the terminal to be invokable, and taking the scheduling state as a comparison result.
And when the base station determines that the signal intensity of the cell where the terminal is positioned is lower than that of the adjacent cell, setting the scheduling state corresponding to the terminal as non-invokable, and taking the scheduling state as a comparison result.
For example, the measurement information reported by the terminal is an a3 entry event, the base station determines that the signal strength of the cell where the terminal is located is lower than that of the neighboring cell based on the measurement information reported by the terminal, sets the scheduling state corresponding to the terminal as unavailable, and takes the scheduling state as the current comparison result of the terminal.
For another example, the measurement information reported by the terminal is an a3 exit event, the base station determines, based on the measurement information reported by the terminal, that the signal strength of the cell in which the terminal is located is higher than that of the neighboring cell, sets the scheduling state corresponding to the terminal to be invocable, and takes the scheduling state as the current comparison result of the terminal.
Therefore, the base station can determine the current signal comparison result of the terminal according to the comparison result of the signal intensity of the cell where the terminal is located and the signal intensity of the adjacent cell, or the comparison result of the signal intensity of the cell where the terminal is located and the signal intensity of the adjacent cell and the current frequency spectrum efficiency of the terminal, so that the quality of the signal comparison result of the terminal can be determined.
Step 130: and the base station judges whether the signal comparison result meets the preset scheduling condition.
In practical application, the base station determines whether the signal comparison result meets a preset scheduling condition, and may include, but is not limited to, the following modes:
the first mode is as follows: and when the signal comparison result is determined to be the comparison result, judging whether the scheduling state corresponding to the comparison result is callable, if so, executing the step 140, otherwise, executing the step 150.
For example, the base station determines that the signal comparison result is the current comparison result of the terminal, and determines that the scheduling status corresponding to the comparison result is callable, then step 140 is executed.
For another example, the base station determines that the signal comparison result is the current comparison result of the terminal, and determines that the scheduling status corresponding to the comparison result is not invokable, then step 150 is executed.
Therefore, the base station can determine the current signal comparison result of the terminal, namely whether the signal intensity of the cell where the terminal is located is higher than that of the adjacent cell or not, according to the scheduling state corresponding to the comparison result, and further judge whether the terminal is called or not according to the scheduling state.
The second way is: and when the signal comparison result is the comparison result and the spectral efficiency, judging whether the scheduling state corresponding to the comparison result is not invokable or not and whether the spectral efficiency is lower than a preset threshold value or not, if so, executing the step 150, otherwise, executing the step 140.
For example, the base station determines the signal comparison result as the comparison result and the spectral efficiency, determines that the scheduling status corresponding to the comparison result is not invokable, and if the spectral efficiency is lower than the preset threshold, then step 150 is executed.
For another example, the base station determines the signal comparison result as the comparison result and the spectrum efficiency, determines that the scheduling status corresponding to the comparison result is callable, and if the spectrum efficiency is higher than the preset threshold, then step 140 is executed. Therefore, the base station can determine the current signal comparison result of the terminal according to the current comparison result and the spectrum efficiency of the terminal, and further determine whether to schedule the terminal according to the quality of the signal comparison result.
Step 140: and the base station schedules the terminal.
Step 150: the base station does not schedule the terminal.
Therefore, the base station can determine the current signal comparison result of the terminal according to the signal comparison result corresponding to the terminal, or the comparison result and the spectrum efficiency, and further, only the terminal with the good signal comparison result is scheduled, but the terminal with the poor signal comparison result is not scheduled, so that the problem of data retransmission caused by the poor signal comparison result is avoided, the interference to other terminals is reduced, the transmission efficiency of each terminal is improved, the resource configuration is optimized, the IoT of a cell is reduced, and the KPI of a network is improved.

Further, the base station determines that the signal comparison result is the current comparison result of the terminal, and determines that the scheduling state corresponding to the comparison result is available, and then schedules the terminal.
The second application scenario is:
the base station monitors the transmission state information of the terminal, obtains a monitoring result, determines that the transmission state information of the terminal represents local transmission data to the terminal according to the monitoring result, and determines that the transmission state information of the terminal meets a preset trigger condition.
