Description

Uplink data transmission method and system, terminal and storage medium
Technical Field
The present invention relates to the field of communications technologies, and in particular, to an uplink data transmission method and system, a terminal, and a storage medium.
Background
With the development of mobile communication technology, people use data services more and more frequently, and the rate of the data services directly affects the user experience. According to the related protocol of 3gpp.ts36.321, as shown in fig. 1, uplink scheduling of a base station is generally divided into the following steps:
1. the terminal UE requests uplink resources from the base station, that is, the terminal sends a Scheduling Request (SR) to the base station. This step tells the base station that there is data to be sent, and the SR will send Uplink Control Information (UCI) in a PUCCH (Physical Uplink Control Channel) in a specified subframe and period according to the configuration of the upper layer. When the base station receives the SR, it issues an UL Grant (Uplink Grant) to the terminal, first allocates a small amount of resources to the terminal, and then the terminal tells the base station how much data needs to be transmitted through a BSR (Buffer State Report).
2. And monitoring the quality of an uplink channel. The base station compares the SRS (Sounding Reference Signal) sent by the terminal with a known Signal to determine the uplink channel sending quality of the terminal, and if the uplink channel sending quality of the terminal is good and data needs to be sent, the base station allocates uplink resources to the terminal for sending the data;
3. the terminal tells the base station that the terminal needs to send data, namely the terminal sends BSR to the base station, and after the base station receives the BSR reported by the terminal, the base station determines whether to allocate resources to the UE according to the comprehensive analysis of the uplink channel quality, the existing resources of the base station and the like;
4. the base station allocates resources according to internal implementation and informs the terminal of which resources the data can be sent on, and the step still informs the terminal through the UL Grant;
5. and finally, the terminal realizes the transmission of uplink data according to the scheduling of the base station.
According to the uplink scheduling procedure, it can be seen that the BSR plays an important role in the process of applying for resources from the base station. If the BSR is not sent, the base station considers that the terminal has no resource to send, and corresponding uplink resources are not allocated to the terminal. According to the specification of the 3gpp.ts36.321 protocol on BSR, there are the following triggering modes for BSR:
1. the terminal periodically sends BSR to the base station according to a periodic BSR Timer periodicBSR-Timer, and the BSR of the type is called periodic BSR (periodic BSR);
2. if new data arrives in the Buffer of the terminal and the priority of the new data is higher than that of the original data in the Buffer, the terminal is triggered to send a regular bsr (regular bsr);
3. the terminal is also triggered to send a regular BSR by the retransmission Timer retxsrb-Timer timeout. The retransmission timer is a timer set to prevent the terminal from not receiving the UL Grant within a certain time after sending the periodic BSR. And when the retransmission timer is overtime, the terminal actively sends the conventional BSR and continues to apply for resources. And when the terminal receives the UL Grant of the newly transmitted data, restarting the retransmission timer.
The difference between the regular BSR and the periodic BSR is that: when a regular BSR is triggered but a terminal does not have enough UL-SCH (Uplink shared Channel) resources for transmitting the BSR, the terminal may transmit an SR request; and when the periodic BSR is triggered but the terminal does not have sufficient UL-SCH resources for transmitting the BSR, the terminal does not transmit the SR request.
Due to the fact that the actual base station network environment is complex, the parameter definitions are also uneven, when the terminal does not receive the UL Grant issued by the base station for a long time, for example, the period of the periodic BSR timer is set to be long, the base station often does not respond to the transmitted BSR due to the fact that the access terminal has many access terminals, and the like, the terminal is required to apply for resources by transmitting the conventional BSR triggered by the retransmission timer, even the SR is transmitted for many times, but the conventional configuration is often insufficient to meet the requirement of uplink transmission, and user experience is affected at this time.

Example 1
Fig. 3 is a schematic flowchart of an uplink data transmission method provided in this embodiment, where the method may be executed by an uplink data transmission system, the system may be implemented in a software and/or hardware manner, the system may include part or all of a terminal and a base station, and the uplink data transmission method is described below with reference to the terminal and the base station as an execution subject, as shown in fig. 3, the uplink data transmission method provided in this embodiment may include:
step S101, the base station sends the period of the retransmission timer to the terminal.
In an example of the specific implementation, the base station sends an RRC (Radio Resource Control) reconfiguration message to the terminal, where the RRC reconfiguration message includes a period of the retransmission timer.
And step S102, the terminal adjusts the period of the retransmission timer according to the space of the buffer occupied by the uplink data packet. The user uses the terminal to do uplink service, namely, sends uplink data to the base station side, generates a corresponding uplink data packet according to the TCP/IP protocol, and stores the uplink data packet in a buffer of the terminal.
In an optional embodiment, as shown in fig. 4, step S102 specifically includes:
step S102a1, determining whether the space occupied by the uplink data packet in the buffer exceeds a first ratio, if yes, performing step S102b 1; if not, go to step S102c 1. The first ratio may be set according to actual conditions, for example, 20% or 50%.
And step S102b1, reducing the period of the retransmission timer.
Step S102c1, maintaining the period of the retransmission timer. In the present embodiment, the period for maintaining the retransmission timer means to maintain the period of the retransmission timer at the original period, that is, the period of the retransmission timer transmitted from the base station to the terminal in step S101.
In this embodiment, when the space occupied by the uplink data packet in the buffer exceeds the first ratio, the period of the retransmission timer for triggering transmission of the regular BSR is reduced, the transmission frequency of the regular BSR is increased to obtain more uplink resources, and meanwhile, the situation that packet loss is forced due to buffer overflow caused by no uplink resources is avoided.
In addition, it should be noted that, with the transmission of uplink data, the space occupied by the buffer by the uplink data packet is dynamically changed, and when the space occupied by the buffer by the uplink data packet is restored from exceeding the first proportion to being lower than the first proportion, the cycle of the retransmission timer needs to be restored to the original cycle, that is, the regular BSR is sent according to the cycle defined by the upper layer, so that the power consumption of the terminal can be saved, meanwhile, the uplink rate can be guaranteed not to be affected, and the user experience is guaranteed.
In another optional embodiment, as shown in fig. 5, step S102 specifically includes:
step S102a2, determining whether the space occupied by the uplink data packet in the buffer exceeds a first ratio, if yes, executing step S102b 2; if not, go to step S102e 2.
Step S102b2, judging whether the space occupied by the uplink data packet in the buffer exceeds a second proportion, if not, executing step S102c 2; if yes, go to step S102d 2.
And step S102c2, reducing the period of the retransmission timer to a first period.
And step S102d2, reducing the period of the retransmission timer to a second period.
Step S102e2, maintaining the period of the retransmission timer.
Wherein the second ratio is higher than the first ratio, and the first period is higher than the second period.
In a specific example, the first ratio is 20%, the second ratio is 80%, the period of the retransmission timer sent by the terminal receiving base station, that is, the original period is sf320, the first period is half of the original period, that is, sf160, and the second period is one-fourth of the original period, that is, sf 80. Where sf320 represents the length of 320 subframes, sf160 represents the length of 160 subframes, and sf80 represents the length of 80 subframes. In this example, when the space occupied by the uplink packet in the buffer is 20% or less, the cycle of the retransmission timer is sf320, when the space occupied by the uplink packet in the buffer is 20% to 80%, the cycle of the retransmission timer is sf160, and when the space occupied by the uplink packet in the buffer is 80% or more, the cycle of the retransmission timer is sf 80.
In this embodiment, when the space occupied by the uplink packet in the buffer exceeds the first ratio and does not exceed the second ratio, the period of the retransmission timer for triggering transmission of the regular BSR is reduced, and the transmission frequency of the regular BSR is increased to obtain more uplink resources; and under the condition that the space occupied by the uplink data packet in the buffer exceeds the second proportion, the period of the retransmission timer is further reduced to obtain more uplink resources, and the condition that the buffer overflows to cause packet loss is avoided.
In another optional embodiment, as shown in fig. 6, step S102 specifically includes:
step S102a3, determining whether the space occupied by the uplink data packet in the buffer exceeds a first ratio, if yes, executing step S102b 3; if not, go to step S102c 3.
Step S102b3, reducing the period of the retransmission timer.
Step S102c3, adjusting the period of the retransmission timer according to the type of the uplink data packet. In a specific implementation, the uplink data packet can be classified according to its description information.
In an alternative embodiment of step S102c3, if the type of the uplink data packet is a predetermined type, the period of the retransmission timer is decreased. In this embodiment, the preset type may be customized according to actual conditions, and the preset type may be one or multiple. In one example, the preset category includes a DNS (Domain Name System) query packet. In another example, the preset category includes a DNS query packet and an RSRA packet. Wherein the RSRA packet is used to obtain ipv6 addresses to establish a link to obtain data transmission.
In one example of implementation, the periods of the retransmission timers in steps S102b3 and S102c3 are reduced to the same period, e.g., both reduced to half of the original period. In another example of the specific implementation, the periods of the retransmission timers in the steps S102b3 and S102c3 are reduced to different periods, which may be set according to actual situations.
In an example of the implementation, the period of the retransmission timer may be reduced to a uniform period for different predetermined types of uplink data packets. In another example of the specific implementation, the preset categories may be divided into different priorities, and the period of the retransmission timer is reduced to a period corresponding to the priority for the preset categories with different priorities. Wherein the higher the priority, the lower the period.
In this embodiment, when the space occupied by the uplink data packet in the buffer does not exceed the first ratio, the period of the retransmission timer is adjusted according to the type of the uplink data packet, specifically, if the type is a preset type, the transmission frequency of the regular BSR is increased by reducing the period of the retransmission timer to obtain more uplink resources, and meanwhile, the situation that the buffer overflows due to the absence of the uplink resources and the packet is lost is avoided.
And step S103, the terminal sends a regular BSR to the base station according to the adjusted cycle of the retransmission timer. In this embodiment, the retransmission timer times out to trigger the terminal to send a regular BSR to the base station, and when the terminal does not have enough UL-SCH resources for sending the BSR, the terminal sends an SR request to the base station to continue applying for resources, so as to ensure the frequency of sending an uplink data packet by the terminal.

The receiving module is used for receiving the period of the retransmission timer sent by the base station.
The adjusting module is used for adjusting the period of the retransmission timer according to the space occupied by the uplink data packet in the buffer.
In an optional implementation manner, the adjusting module specifically includes: a first judging unit, configured to judge whether the space occupied by the uplink data packet in the buffer exceeds a first ratio, and if so, reduce the period of the retransmission timer, and if not, maintain the period of the retransmission timer. The period of maintaining the retransmission timer is to maintain the period of the retransmission timer at an original period, that is, the period of the retransmission timer transmitted from the base station to the terminal.
In this embodiment, when the space occupied by the uplink data packet in the buffer exceeds the first ratio, the period of the retransmission timer for triggering the transmission of the regular BSR is reduced, the transmission frequency of the regular BSR is increased to obtain more uplink resources, and meanwhile, the situation that packet loss is forced due to the overflow of the buffer due to no uplink resources is avoided.
In addition, it should be noted that, with the transmission of uplink data, the space occupied by the buffer by the uplink data packet is dynamically changed, and when the space occupied by the buffer by the uplink data packet is restored from exceeding the first proportion to being lower than the first proportion, the period of the retransmission timer needs to be restored to the original period, that is, a conventional BSR is sent according to the period defined by the upper layer, so that the power consumption of the terminal can be saved, and meanwhile, the uplink rate can be guaranteed not to be affected, and the user experience is guaranteed.
In an optional implementation manner, the adjusting module further includes an adjusting unit.
The first judging unit is also used for calling the adjusting unit when the space occupied by the uplink data packet in the buffer does not exceed the first proportion.
The adjusting unit is configured to adjust a period of the retransmission timer according to a type of the uplink data packet.
In an optional embodiment, the adjusting unit is specifically configured to decrease the period of the retransmission timer when the type of the uplink data packet is a preset type.
In an example of the implementation, the period of the retransmission timer may be reduced to a uniform period for different predetermined types of uplink data packets. In another example of the specific implementation, the preset categories may be divided into different priorities, and the period of the retransmission timer is reduced to a period corresponding to the priority for the preset categories with different priorities. Wherein the higher the priority, the lower the period.
In this embodiment, when the space occupied by the uplink data packet in the buffer does not exceed the first ratio, the period of the retransmission timer is adjusted according to the type of the uplink data packet, specifically, if the type is a preset type, the transmission frequency of the regular BSR is increased by reducing the period of the retransmission timer to obtain more uplink resources, and meanwhile, the situation that the buffer overflows due to the absence of the uplink resources and the packet is lost is avoided.
In another optional embodiment, the adjusting module specifically includes a second judging unit and a third judging unit.
The second judging unit is used for judging whether the space occupied by the uplink data packet in the buffer exceeds the first proportion and is lower than the second proportion, and if so, the period of the retransmission timer is reduced to the first period.
The third determining unit is configured to determine whether the space occupied by the uplink data packet in the buffer exceeds a second ratio, and if so, decrease the period of the retransmission timer to a second period.
Wherein the second ratio is higher than the first ratio, and the first period is higher than the second period.
In this embodiment, when the space occupied by the uplink packet in the buffer exceeds the first ratio and does not exceed the second ratio, the period of the retransmission timer for triggering transmission of the regular BSR is reduced, and the transmission frequency of the regular BSR is increased to obtain more uplink resources; and under the condition that the space occupied by the uplink data packet in the buffer exceeds the second proportion, the period of the retransmission timer is further reduced to obtain more uplink resources, and the condition that the buffer overflows to cause packet loss is avoided.
And the sending module is used for sending the regular BSR according to the adjusted cycle of the retransmission timer. In this embodiment, the retransmission timer times out to trigger the terminal to send a regular BSR to the base station, and when the terminal does not have enough UL-SCH resources for sending the BSR, the terminal sends an SR request to the base station to continue applying for resources, so as to ensure the frequency at which the terminal sends an uplink data packet.
