Description
Technical Field
The embodiment of the invention relates to the technical field of mobile communication, in particular to a prescheduling duration control method and a base station.
Background
In Long Term Evolution (LTE) of the universal mobile telecommunications technology, uplink scheduling refers to a base station scheduler dynamically selecting which terminals are scheduled according to various grasped information and how much transmission resources are allocated to the terminals. The scheduler can maximize the system throughput or optimize the user experience according to different scheduling purposes and different algorithms, and can also pursue a certain balance between the two. Currently, uplink scheduling is mainly triggered by User Equipment (UE), and mainly includes the following procedures:
1. the UE transmits an Uplink Scheduling Request (SR) through an Uplink Control Information (UCI) in a Physical Uplink Control Channel (PUCCH) to Request an Uplink resource from a base station (Evolved Node B, eNB);
2. after receiving the SR, the eNB issues a UL grant permission;
3. the UE informs the eNB of the data volume needing to be transmitted;
4. after receiving a Buffer State Report (BSR) reported by the UE, the eNB determines how to allocate resources to the UE for data transmission according to a Sounding Reference Signal (SRS) reported by the UE and a comprehensive analysis of existing resources of the eNB.
However, when the UE transmits Uplink data each time, if there is no Physical Uplink Shared Channel (PUSCH) resource, the UE needs to apply for the PUSCH through the SR, which undoubtedly results in an increase in Uplink data delay, thereby affecting the perception of the user. Therefore, in order to reduce uplink delay, an uplink prescheduling mechanism is introduced.
The uplink pre-scheduling mechanism allocates a certain uplink resource to the UE in advance, and the UE does not need to apply through an SR process, so that the time delay of uplink data can be reduced. Meanwhile, after the pre-scheduling mechanism is started, if the UE has no real data, a padding (padding) packet is also sent, which causes null scheduling, so that uplink data sent by the UE is increased, thereby increasing Interference over Thermal (IoT). Therefore, the core problem of current prescheduling is how to reduce IoT rise as much as possible on the basis of optimizing latency.
In order to solve the above problem, the conventional mechanism mainly reduces IoT degradation caused by pre-scheduling by limiting the number of Physical Resource Blocks (PRBs) of a single subframe pre-scheduling or limiting the uplink pre-scheduling duration.
However, in some cases, ioT cannot be effectively reduced by limiting the total number of PRBs in a single subframe or limiting the uplink pre-scheduling duration, because in a cell, there may exist some UEs in the uplink pre-scheduling duration, only a small part of data in the data that is passed through the pre-scheduling is real data, and the rest is padding packets. Therefore, setting the same total number of PRBs or uplink prescheduling duration for all UEs in a cell does not effectively reduce IoT.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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 some, but not all, embodiments of the present invention. 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.
Fig. 1 shows a flowchart of a method for controlling a pre-scheduling duration according to an embodiment of the present invention.
As shown in fig. 1, a method for controlling a pre-scheduling duration according to an embodiment of the present invention is applied to a base station, and the method includes:
The preset period of the uplink pre-scheduling may be preset. The preset period may be set to a short time value, such as 10 seconds, 30 seconds, and in the current preset period, a first pre-scheduling parameter of a last preset period of the terminal is obtained;
the uplink pre-scheduling parameter is a ratio of an effective pre-scheduling frequency of the uplink pre-scheduling operation to a total pre-scheduling frequency, and the first pre-scheduling parameter is an uplink pre-scheduling parameter of a previous preset period. If the uplink data sent by the user corresponding to the pre-scheduling operation includes real data, but not all packets, the pre-scheduling is effective.
Specifically, the uplink pre-scheduling parameter may be determined according to the following formula 1:
equation 1:
wherein, P is an uplink pre-scheduling parameter, N1 is an effective pre-scheduling frequency, and N2 is a total pre-scheduling frequency.
The preset corresponding relation is a mapping relation between an uplink pre-scheduling parameter and a pre-scheduling time length, the first pre-scheduling time length of the terminal in the preset period is determined according to the preset corresponding relation and the first pre-scheduling parameter of the terminal, and the pre-scheduling time length of each terminal can be controlled respectively.
Due to the fact that the service conditions of all the terminals are different, the pre-scheduling duration is controlled respectively, and the IoT can be prevented from being lifted. For example, for a terminal with a higher first pre-scheduling parameter, the allocated first pre-scheduling duration is longer, and for a terminal with a lower first pre-scheduling parameter, the allocated first pre-scheduling duration is shorter, so that a situation that more padding packets are uploaded by a terminal with a lower first pre-scheduling parameter due to the same pre-scheduling restriction measure applied to all terminals in the cell can be avoided.
And 103, controlling the duration of the uplink prescheduling operation of the terminal according to the first prescheduling duration.
The method comprises the steps that the duration of uplink pre-scheduling operation of a terminal is controlled according to a first pre-scheduling duration, and users of different service models are realized and correspond to different pre-scheduling durations; the uplink prescheduling duration time can be configured in a self-adaptive mode according to the prescheduling condition of a preset period on the terminal, and is not set uniformly in a cell level. The terminal with higher uplink pre-scheduling parameters in the last preset period, that is, the frequency of effective pre-scheduling is higher, because the time of the preset period is shorter, the real uplink data that the terminal needs to send is still more in the current preset period, and therefore, the terminal is configured with longer pre-scheduling duration. Similarly, for a terminal corresponding to a lower gear, the effective pre-scheduling frequency is lower, and a shorter pre-scheduling duration is configured, so that the situation that too many padding packets are sent to cause the lifting of the IoT is avoided.
In the above embodiment of the present invention, a first pre-scheduling parameter of a terminal is obtained, a first pre-scheduling duration corresponding to the first pre-scheduling parameter is determined according to a preset corresponding relationship between an uplink pre-scheduling parameter and a pre-scheduling duration, and a duration of an uplink pre-scheduling operation of the terminal is controlled according to the first pre-scheduling duration; the uplink pre-scheduling duration time in the current period is controlled according to the pre-scheduling condition of the last preset period of the terminal, the uplink pre-scheduling duration time of the terminal is configured adaptively and dynamically, and the terminals of different service models correspond to different uplink pre-scheduling duration times, so that more padding packets caused by improper configuration are avoided, and the IoT is reduced. The invention solves the problem that the IoT can not be effectively reduced by limiting the total PRB number of the single subframe pre-scheduling or limiting the uplink pre-scheduling duration in the prior art.
Preferably, in the embodiment of the present invention, the preset corresponding relationship includes at least two gears of the uplink pre-scheduling parameter, and the gear to which the larger uplink pre-scheduling parameter belongs is not lower than the gear to which the smaller uplink pre-scheduling parameter belongs;
each gear corresponds to different pre-scheduling time lengths, and the gears and the pre-scheduling time lengths are in a direct proportion relation.
The preset corresponding relation comprises a threshold value, and the uplink pre-scheduling parameters are divided into at least two different gears through the threshold value; each gear corresponds to a numerical value interval of the uplink pre-scheduling parameter, and the gear to which the larger uplink pre-scheduling parameter belongs is not lower than the gear to which the smaller uplink pre-scheduling parameter belongs.
As a specific example, when there is a threshold value N1, the correspondence relationship includes two gears, namely, a D1 gear and a D2 gear (the D1 gear is higher than the D2 gear), and if the uplink pre-scheduling parameter is greater than N1, the uplink pre-scheduling parameter belongs to the D1 gear; if the uplink pre-scheduling parameter is smaller than N1, the uplink pre-scheduling parameter belongs to D2 grade; when the uplink pre-scheduling parameter is equal to N1, the uplink pre-scheduling parameter may be divided into a D1 gear or a D2 gear, which is not limited herein in the embodiments of the present invention.
Each gear corresponds to different pre-scheduling time lengths, and the gear and the pre-scheduling time lengths are in a direct proportion relationship, that is, the pre-scheduling time length corresponding to a higher gear is longer than the pre-scheduling time length corresponding to a lower gear, for example, in the above example, the pre-scheduling time length corresponding to the D1 gear is longer than the pre-scheduling time length corresponding to the D2 gear. Because the uplink pre-scheduling parameter of the terminal corresponding to the higher gear in the last preset period is higher, that is, the frequency of effective pre-scheduling is higher, and because the time of the preset period is shorter, the real uplink data that the terminal needs to send in the current preset period is still more, so that the terminal is configured with longer pre-scheduling duration. Similarly, for a terminal corresponding to a lower gear, the frequency of effective pre-scheduling is lower, and a shorter pre-scheduling duration is configured, so that excessive padding packet transmission and IoT lifting are avoided.
Optionally, in this embodiment of the present invention, the step of controlling a duration of an uplink pre-scheduling operation of the terminal according to the first pre-scheduling duration includes:
and controlling the operation duration of each uplink pre-scheduling operation of the terminal in the current preset period to be the first pre-scheduling duration.
Specifically, for each terminal, the operation duration of each uplink pre-scheduling operation of the terminal in the current preset period is controlled to be the first pre-scheduling duration, so that the uplink pre-scheduling duration of the terminal in the current preset period is dynamically adjusted according to the pre-scheduling condition of the terminal in the previous preset period.
Preferably, in the embodiment of the present invention, the step of obtaining the first pre-scheduling parameter of the terminal in a preset period includes:
and obtaining the effective pre-scheduling times of the uplink pre-scheduling operation of the terminal in a preset period.
The step of obtaining the first pre-scheduling parameter of the last preset period of the terminal comprises obtaining the effective pre-scheduling times of the uplink pre-scheduling operation of the last preset period of the terminal and obtaining the total pre-scheduling times of the uplink pre-scheduling operation of the last preset period of the terminal. The number of effective pre-scheduling times is the number of effective uplink pre-scheduling operations, and the base station or the terminal can record the number of effective uplink pre-scheduling operations occurring at the terminal, so as to facilitate subsequent determination of uplink pre-scheduling parameters (as in the first case below).
Preferably, in the embodiment of the present invention, the step of obtaining the effective pre-scheduling times of the uplink pre-scheduling operation in a preset period at the terminal includes two cases, namely a case one and/or a case two, specifically:
in the first situation, the base station obtains the effective pre-scheduling times of the uplink pre-scheduling operation of the terminal in a preset period, which are recorded in advance by the base station.
In case one, in each preset period, the base station counts the number of times of the effective uplink pre-scheduling operation, for example, in each uplink pre-scheduling operation, the base station counts the PUSCH scheduled by the terminal according to the pre-scheduling condition, and determines whether the operation is an effective pre-scheduling operation: if a Protocol Data Unit (PDU) of a Media Access Control (MAC) layer of the PUSCH corresponding to the uplink pre-scheduling operation includes a payload of a non-MAC layer, determining that the uplink pre-scheduling operation is an effective pre-scheduling operation; therefore, if the payload (payload) of the MAC PDU includes the payload of the non-MAC layer in addition to the MAC control message, it may be determined that the payload of the non-MAC layer is the real uplink data of the terminal.
Acquiring a protocol data unit PDU of a media access control MAC layer of a physical uplink shared channel resource PUSCH of each uplink prescheduling operation of the terminal in a previous preset period;
for each uplink pre-scheduling operation, if the PDU of the MAC layer of the PUSCH corresponding to the uplink pre-scheduling operation comprises a payload of a non-MAC layer, determining that the uplink pre-scheduling operation is an effective pre-scheduling operation;
and determining the number of the effective pre-scheduling operation, wherein the number of the effective pre-scheduling operation is the effective pre-scheduling number.
When the number of times of effective uplink pre-scheduling operation of the terminal in a previous preset period is obtained, the terminal can also obtain the PDU of the MAC layer of the PUSCH of each uplink pre-scheduling operation of the terminal in the previous preset period, and whether the uplink pre-scheduling operation is the effective uplink pre-scheduling operation is judged in real time according to the PDU of the MAC layer; and determining the total times of the effective uplink pre-scheduling operation.
In the embodiment of the present invention, a first pre-scheduling parameter of a terminal is obtained, a first pre-scheduling duration corresponding to the first pre-scheduling parameter is determined according to a preset corresponding relationship between the uplink pre-scheduling parameter and a pre-scheduling duration, and the duration of an uplink pre-scheduling operation of the terminal is controlled according to the first pre-scheduling duration; the uplink prescheduling duration time in the current period is controlled according to the prescheduling condition of a preset period on the terminal, so that the uplink prescheduling duration time of the terminal is adaptively and dynamically configured; and the terminals of different service models correspond to different uplink pre-scheduling durations, and for the terminal with a higher effective uplink pre-scheduling operation rate in the previous preset period, the longer uplink pre-scheduling duration is configured, otherwise, the shorter uplink pre-scheduling duration is configured, so that more padding packets caused by improper configuration are avoided, and the IoT is reduced.
Fig. 2 is a schematic flow chart illustrating a method for controlling a pre-scheduled time period according to another embodiment of the present invention, where in this embodiment, the corresponding relationship includes three gears.
As shown in fig. 2, the method for controlling a pre-scheduling duration provided in the embodiment of the present invention is applied to a base station, and the method includes:
The preset period of the uplink pre-scheduling may be preset. The preset period can be set to a short time value, such as 10 seconds and 30 seconds, and in the current preset period, a first pre-scheduling parameter of a preset period on the terminal is obtained;
the uplink pre-scheduling parameter is a ratio of effective pre-scheduling times of the uplink pre-scheduling operation to total pre-scheduling times, and the first pre-scheduling parameter is an uplink pre-scheduling parameter of a previous preset period. The effective pre-scheduling means that if the uplink data sent by the user corresponding to the pre-scheduling operation includes real data, but not all packets, the pre-scheduling is effective pre-scheduling.
The preset corresponding relation is a mapping relation between an uplink pre-scheduling parameter and a pre-scheduling time length, the first pre-scheduling time length of the terminal in the preset period is determined according to the preset corresponding relation and the first pre-scheduling parameter of the terminal, and the pre-scheduling time length of each terminal can be controlled respectively.
Specifically, the preset correspondence relationship can be represented by the following table 1:
table 1:
| uplink pre-scheduling parameters | Gear position | Prescheduling duration |
| P1<X<P2 | M1 | T1 |
| P2<X<P3 | M2 | T2 |
| P3<X<P4 | M3 | T3 |
Wherein, X, P1-P6 are uplink pre-scheduling parameters, and P1< P2< P3< P4< P5< P6;
m1, M2 and M3 are gears, and M1 is lower than M2 and lower than M3;
t1, T2 and T3 are gears, the duration of T3 is longer than that of T2, and the duration of T2 is longer than that of T1;
when P1< X < P2, the corresponding gear is M1, and the corresponding pre-scheduling duration is T1.
When X = P1, P2, or P3, the corresponding gear may be the previous gear or the next gear, and the embodiment of the present invention is not limited herein.
Because the service conditions of each terminal are different, the uplink pre-scheduling duration is controlled respectively, and the lifting of the IoT can be avoided. For example, for a terminal with a first uplink pre-scheduling parameter and a higher first pre-scheduling parameter, the allocated first uplink pre-scheduling duration is longer, and for a terminal with a first uplink pre-scheduling parameter and a lower first pre-scheduling parameter, the allocated first uplink pre-scheduling duration is shorter, so that the situation that more padding packets are uploaded by terminals with the first uplink pre-scheduling parameter and the lower first pre-scheduling parameter due to the same pre-scheduling limitation measure for all terminals in a cell can be avoided.
And 203, controlling the duration of the uplink pre-scheduling operation of the terminal according to the first pre-scheduling duration.
The method comprises the steps that uplink pre-scheduling duration of a terminal is controlled according to a first pre-scheduling duration, users of different service models are achieved, and the different pre-scheduling durations correspond to the users; the uplink prescheduling duration time can be configured in a self-adaptive mode according to the prescheduling condition of a preset period on the terminal, and is not set uniformly in a cell level. The terminal with higher uplink pre-scheduling parameters in the last preset period, that is, the effective pre-scheduling frequency is higher, and because the time of the preset period is shorter, the real uplink data that the terminal needs to send in the current preset period is still more, so that a longer pre-scheduling duration is configured for the terminal. Similarly, for a terminal corresponding to a lower gear, the frequency of effective pre-scheduling is lower, and a shorter pre-scheduling duration is configured, so that excessive padding packet transmission and IoT lifting are avoided.
In the above embodiment of the present invention, a first pre-scheduling parameter of a terminal is obtained, a first pre-scheduling duration corresponding to the first pre-scheduling parameter is determined according to a preset corresponding relationship between an uplink pre-scheduling parameter and a pre-scheduling duration, and a duration of an uplink pre-scheduling operation of the terminal is controlled according to the first pre-scheduling duration; the uplink pre-scheduling duration time in the current period is controlled according to the pre-scheduling condition of the last preset period of the terminal, the uplink pre-scheduling duration time of the terminal is configured adaptively and dynamically, and the terminals of different service models correspond to different uplink pre-scheduling duration times, so that more padding packets caused by improper configuration are avoided, and the IoT is reduced.
