Technical Field
The present disclosure relates to the field of communications technologies, and in particular, to a data transmission method, an apparatus, a terminal, and a storage medium.
Background
During communication, data transmission between electronic devices is bursty, with data transmission during a period of time, but not during a subsequent period of time. Therefore, Discontinuous Reception (DRX) is often used for data transmission. That is, when there is no data transmission, the power consumption can be reduced by stopping receiving a Physical Downlink Control Channel (PDCCH), thereby increasing the service time of the battery of the electronic device.
In the related art, usually, in order to save power consumption, during data transmission, a mode of performing parallel uplink and downlink transmission is adopted for data transmission, that is, a sending end accumulates a certain number of data packets and then sends the data packets to a receiving end, so that the situation that the load of a processor of the receiving end is aggravated due to frequent startup and dormancy of the receiving end for receiving data is avoided, and meanwhile, in order to realize parallel uplink and downlink data transmission, the starting time of the DRX cycles of the uplink and the downlink can be aligned.
In the related art, although the mode of performing data transmission simultaneously can bring benefits in terms of power consumption, when uplink and downlink data are concurrent, the DDR bandwidth of the data transmission system is the sum of the uplink DDR bandwidth and the downlink DDR bandwidth, so that after DRX cycles are aligned, the requirement for the DDR bandwidth is too high, and data transmission fails.

Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
Reference herein to "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. In addition, the relevant data referred to in the present application may be data authorized by the user or sufficiently authorized by each party.
It should be noted that information (including but not limited to user equipment information, user personal information, etc.), data (including but not limited to data for analysis, stored data, displayed data, etc.), and signals referred to in this application are authorized by the user or sufficiently authorized by various parties, and the collection, use, and processing of the relevant data is required to comply with relevant laws and regulations and standards in relevant countries and regions. For example, the target data amount, the first data transmission period, the second data transmission period, and the like referred to in this application are all obtained with sufficient authorization.
Referring to fig. 1, a schematic diagram of an implementation environment related to a data transmission method according to an exemplary embodiment of the present application is shown. The implementation environment includes a transmitting end 10 and a receiving end 20. The transmitting end 10 and the receiving end 20 communicate with each other through a network.
In order to reduce power consumption, the transmitting end 10 and the receiving end 20 perform data transmission according to a data transmission cycle. The data transmission period comprises a first data transmission period of the uplink data transmission link and a second data transmission period of the downlink data transmission link. The first data transmission period and the second data transmission period each include an active period and a sleep period. In the activation time period, the data transmission link is in a power-on state and can perform data transmission, in the sleep time period, the data transmission link is in a power-off state, and in the sleep time period, the data transmission link does not perform data transmission. Therefore, in the data transmission process, the data transmission link does not need to be in a power-on state all the time, and the power consumption is further reduced.
In the process of Data transmission, Data transmitted in the processes of uplink Data transmission and downlink Data transmission are transmitted through a Double Data Rate (DDR) memory, wherein the DDR memory is used for caching Data to be transmitted. Thus, the DDR bandwidth may limit the efficiency of data transfer and the transfer results.
In some embodiments, the receiving end 20 and the transmitting end 10 are terminals having a wireless communication function. Both the receiving end 20 and the transmitting end 10 may be mobile terminals, such as mobile phones (or "cellular" phones), and computers with mobile terminals, such as portable, pocket, hand-held, computer-embedded, or vehicle-mounted mobile devices. The receiving end 20 and the transmitting end 10 may also be a mobile phone, a tablet computer, a computer with a wireless communication function, or a wearable device. In the embodiments of the present application, this is not particularly limited.
Referring to fig. 2, a flow chart of a data transmission method according to an exemplary embodiment of the present application is shown. The method comprises the following steps:
step S201: the terminal determines a target data volume, wherein the target data volume is a data volume transmitted by an uplink data transmission link within a first time length, and the first time length is a time length corresponding to an activation time period in a first data transmission cycle of the uplink data transmission link.
The target data amount is a data amount of data transmitted by the uplink data transmission link in an active period of a first data transmission cycle. In some embodiments, the terminal predicts the data amount that needs to be transmitted by the uplink data transmission link of the data transmission each time the data transmission is performed. In some embodiments, the terminal determines the maximum amount of data that can be transmitted by the uplink data transmission link in each data transmission period according to a first duration corresponding to the active time period in the first data transmission period of the uplink data transmission link and a bandwidth provided by the uplink data transmission link for the uplink data transmission link, where the bandwidth is provided by the DDR.
Accordingly, in some embodiments, the terminal reads the data amount of the data buffered in the memory to obtain the target data amount, and the memory is used for buffering the data transmitted by the uplink data transmission link within the first time period. When the terminal transmits data through an uplink, data to be transmitted is firstly cached in the memory, and when the time reaches the starting time of the activation time period of the first data transmission period, the terminal transmits the data cached in the memory through the uplink data transmission link. In this implementation manner, the terminal determines the target data volume of the data transmission before the activation time period of each data transmission cycle, so that the data transmission bandwidth corresponding to the target data volume can be adjusted more accurately.
In some embodiments, the terminal determines the target data amount based on the first data transmission bandwidth and the first duration. The transmission rate of data transmission in the uplink and downlink data transmission link is affected by the bandwidth of the data transmission link, i.e. the maximum transmission rate does not exceed the maximum bandwidth of the data transmission link. Therefore, in this embodiment of the present application, the first data transmission bandwidth is used as the data transmission rate, the product of the first data parameter bandwidth and the first time duration is used as the maximum data amount that can be transmitted by the uplink data transmission link within the first time duration, and the maximum data amount is used as the target data amount. In the embodiment of the application, the maximum data volume which can be transmitted by the uplink data transmission link within the first time period is used as the target data volume, so that the maximum data volume which can be transmitted by the original data transmission bandwidth can be transmitted after the data transmission bandwidth is adjusted by the uplink data transmission link, and the target data volume for data transmission at this time does not need to be determined when the data transmission is performed at this time, thereby improving the efficiency of data transmission.
It should be noted that the terminal may be a receiving end or a transmitting end, and in this embodiment, this is not specifically limited.
Step S202: and the terminal determines a second time length of the downlink data transmission link, wherein the second time length is a time length corresponding to the activation time period in a second data transmission period of the downlink data transmission link.
The downlink data transmission link is a data transmission link bound to an uplink data transmission link of the terminal. The second data transmission period and the first data transmission period have the same duration. The duration of the first data transmission period and the duration of the second data transmission period are set according to needs, and this is not particularly limited in the embodiment of the present application. The second duration is a duration corresponding to the activation time period in the second data transmission cycle. The second duration is less than the duration of the second data transmission period, and the second duration is set according to needs.
In some embodiments, the terminal caches relevant information of the currently used second data transmission period, where the relevant information includes a duration of the second data transmission period and a duration corresponding to an activation time period in the second data transmission period. Correspondingly, the terminal reads the cached related information and acquires the second duration from the related information. In some embodiments, the terminal records a duration corresponding to the activation time period in the second data transmission cycle through a timer, and stores the activation time period locally. And when the second time length needs to be acquired, reading the second time length from a local storage, or determining a timing result of the timer as the second time length.
Step S203: and the terminal adjusts the first data transmission bandwidth of the uplink data transmission link based on the target data volume and the second time length to obtain a second data transmission bandwidth.
The second data transmission bandwidth is less than the first data transmission bandwidth. In this step, the terminal adjusts the duration of the activation time period for data transmission in the first data transmission cycle from the first duration to the second duration, so that the data corresponding to the target data volume can be transmitted within the second duration, which reduces the requirement for bandwidth in unit time, and thus adjusts the first data transmission bandwidth to the second data transmission bandwidth, i.e., reduces the requirement for bandwidth, and also ensures the throughput of the data transmission system.
Step S204: and the terminal transmits the data to be transmitted through the uplink data transmission link in the activation time period in the second data transmission cycle based on the second data transmission bandwidth.
In this step, the terminal sends the data to be transmitted by the uplink data transmission link to other terminals based on the adjusted second data transmission bandwidth and the activated time period in the second data transmission cycle. Correspondingly, the terminal transmits the data to be transmitted by taking the second data transmission bandwidth as a transmission rate and taking the second duration corresponding to the activation time period in the second data transmission cycle as a transmission duration.
Referring to fig. 3, the first data transmission bandwidth of the uplink data transmission link of the terminal is X, the first time duration is t1, the third data transmission bandwidth of the downlink data transmission link is Y, the second time duration is t2, and before the first data bandwidth of the uplink data transmission link is adjusted, the data transmission bandwidth of the terminal in the time period of t1 is X + Y; the terminal adjusts the data transmission duration of the uplink data transmission link to a second duration from a first duration, adjusts the data transmission bandwidth of the uplink data transmission link from the first data transmission bandwidth to a second data transmission bandwidth Z, wherein the second data transmission bandwidth Z is smaller than the first data transmission bandwidth X, after adjustment, the data transmission bandwidth of the terminal in a time period t2 is Z + Y, and the terminal performs data transmission based on the adjusted data transmission bandwidth and the adjusted data transmission duration.
In the embodiment of the application, the data transmitted by the uplink transmission link is averaged to the second duration corresponding to the downlink data transmission link, so that the problem that in the initial stage of data transmission, when data transmission is performed, data impact is generated due to large bandwidths of the uplink data transmission link and the downlink data transmission link, so that the bandwidth is insufficient, and further data transmission failure is caused is solved.
Referring to fig. 4, a flowchart of a data transmission method according to an exemplary embodiment of the present application is shown. The method comprises the following steps:
step S401: the terminal determines a target data volume, wherein the target data volume is a data volume transmitted by an uplink data transmission link within a first time length, and the first time length is a time length corresponding to an activation time period in a first data transmission cycle of the uplink data transmission link.
This step is the same as the principle of step S201, and is not described herein again.
Step S402: and the terminal determines a second time length of the downlink data transmission link, wherein the second time length is a time length corresponding to the activation time period in a second data transmission period of the downlink data transmission link.
The principle of this step is the same as that of step S202, and is not described herein again.
Step S403: the terminal determines a target data transmission rate based on the second duration and the target data amount.
Correspondingly, in the embodiment of the present application, the terminal determines a quotient of the target data size and the second time length as the target data transmission rate. In this way, the quotient of the target data volume and the second time length is determined as the target transmission rate, and the quotient of the target data volume and the second time length is determined as the data transmission rate because the target data volume is the maximum data volume which can be transmitted by the uplink data transmission link, so that the data throughput is not influenced.
Step S404: and the terminal determines the data transmission bandwidth matched with the target data transmission rate as the second data transmission bandwidth.
The transmission rate of data is positively correlated with the transmission bandwidth of data. In some embodiments, the value of the terminal target data transmission rate is used as the value of the data transmission bandwidth matching the target data transmission rate to obtain the second data transmission bandwidth. In some embodiments, the terminal determines, based on the target data transmission rate, a second data transmission bandwidth matched with the target data transmission rate according to the corresponding relationship between the data transmission rate and the data transmission bandwidth. The corresponding relationship between the data transmission rate and the data transmission bandwidth may be determined according to any relationship algorithm between the data transmission rate and the data transmission bandwidth, which is not specifically limited in this embodiment of the present application.
Step S405: and the terminal transmits the data to be transmitted through the uplink data transmission link in the activation time period in the second data transmission cycle based on the second data transmission bandwidth.
The principle of this step is the same as that of step S204, and is not described herein again.
In the embodiment of the application, the data transmitted by the uplink transmission link is averaged to the second duration corresponding to the downlink data transmission link, so that the problem that in the initial stage of data transmission, when data transmission is performed, data impact is generated due to large bandwidths of the uplink data transmission link and the downlink data transmission link, so that the bandwidth is insufficient, and further data transmission failure is caused is solved.
In some embodiments, the terminal is configured to employ a modem (modem) and an Access Point (AP). The modem and the AP are connected through a PCIE interface, and the PCIE is electrified through a hardware accelerator, so that the activation and the dormancy of the modem and the AP are controlled. In order to prevent the power consumption waste caused by the fact that the hardware accelerator keeps the power-on state of the PCIE in the sleep time of the data transmission period. In an embodiment of the present application, a power-on state of the hardware accelerator is adjusted based on a data transmission period of a downlink data transmission link, and referring to fig. 5, a flowchart of a data transmission method according to an exemplary embodiment of the present application is shown. The method comprises the following steps:
step S501: the terminal determines a target data volume, wherein the target data volume is a data volume transmitted by an uplink data transmission link within a first time length, and the first time length is a time length corresponding to an activation time period in a first data transmission cycle of the uplink data transmission link.
This step is the same as the principle of step S201, and is not described herein again.
Step S502: and the terminal determines a second time length of the downlink data transmission link, wherein the second time length is a time length corresponding to the activation time period in a second data transmission period of the downlink data transmission link.
The principle of this step is the same as that of step S202, and is not described herein again.
Step S503: and the terminal adjusts the first data transmission bandwidth of the uplink data transmission link based on the target data volume and the second time length to obtain a second data transmission bandwidth.
The principle of this step is the same as that of step S203, and is not described herein again.
Step S504: and the terminal controls the operation state of a hardware accelerator based on the second data transmission period of the downlink data transmission link, and the hardware accelerator is used for controlling the data transmission of the downlink data transmission link and the uplink data transmission link based on the operation state.
Referring to fig. 6, in the embodiment of the present application, the duration of the power-on state of the hardware accelerator is kept consistent with the second data transmission period, before entering the activation period, the terminal wakes up the hardware accelerator to operate the hardware accelerator, and during the sleep period, the terminal controls the hardware accelerator to also enter the sleep state. Correspondingly, in response to that the current time reaches the activation time of the downlink data transmission link, the terminal controls the hardware accelerator to enter an activation state, and when the hardware accelerator is in the activation state, the hardware accelerator is used for controlling the uplink data transmission link and the downlink data transmission link to perform data transmission; and in response to that the activation duration of the hardware accelerator reaches the second duration, the terminal controls the hardware accelerator to enter a sleep state, and when the hardware accelerator is in the sleep state, the hardware accelerator is used for controlling the uplink data transmission link and the downlink data transmission link to stop data transmission.
It should be noted that this step may also be executed before step S201, and in the embodiment of the present application, the execution order of this step is not particularly limited.
Step S505: and the terminal controls an uplink data transmission link through the hardware accelerator, and transmits the data to be transmitted through the uplink data transmission link within the activation time period in the second data transmission cycle based on the second data transmission bandwidth.
The principle of this step is the same as that of step S204, and is not described herein again.
In the embodiment of the application, the duration of the power-on state of the hardware accelerator is kept consistent with the second data transmission period, the terminal wakes up the hardware accelerator before entering the activation time period to enable the hardware accelerator to work, and the terminal controls the hardware accelerator to also enter the sleep state in the sleep time period, so that the power-on of the uplink and downlink data transmission links in the sleep time period of the data transmission period is prevented, the power consumption of the terminal is further saved, and the service life of the battery is further prolonged.
