During the communication process, data transmission between electronic devices is sudden. There is data transmission for a period of time, but there is no data transmission for the next period of time. Therefore, discontinuous reception (DRX) is often used for data transmission. That is, when there is no data transmission, power consumption can be reduced by stopping receiving the Physical Downlink Control Channel (PDCCH), thereby increasing the battery life of the electronic device.

In related technologies, in order to save power consumption, data is usually transmitted in parallel uplink and downlink transmission, that is, the sender accumulates a certain number of data packets and then sends them to the receiver, thereby avoiding the need for the receiver to Being able to receive data and frequently start and sleep will increase the load on the receiving end processor. At the same time, in order to facilitate upstream and downstream data transmission in parallel, the starting times of the upstream and downstream DRX cycles will be aligned.

In the above related technologies, although simultaneous data transmission 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. Therefore, the DRX cycle After alignment, the requirements for DDR bandwidth are too high, resulting in data transmission failure.

Detailed ways

In order to make the purpose, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

The "plurality" mentioned in this article means two or more than two. "And/or" describes the relationship between related objects, indicating that there can be three relationships. For example, A and/or B can mean: A exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the related objects are in an "or" relationship. In addition, the relevant data involved in this application can be data authorized by the user or fully authorized by all parties.

It should be noted that the information (including but not limited to user equipment information, user personal information, etc.), data (including but not limited to data used for analysis, stored data, displayed data, etc.) and signals involved in this application, All are authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data need to comply with relevant laws, regulations and standards of relevant countries and regions. For example, the target data volume, first data transmission period and second data transmission period involved in this application are all obtained with full authorization.

Please refer to FIG. 1 , which shows a schematic diagram of the implementation environment involved in the data transmission method provided by an exemplary embodiment of the present application. The implementation environment includes a sending end 10 and a receiving end 20 . The sending end 10 and the receiving end 20 communicate through the network.

In order to reduce power consumption, the sending end 10 and the receiving end 20 perform data transmission according to the data transmission cycle. The data transmission period includes a first data transmission period of the uplink data transmission link and a second data transmission period of the downlink data transmission link. Both the first data transmission period and the second data transmission period include an activation period and a sleep period. During the activation period, the data transmission link is powered on and can transmit data. During the sleep period, the data transmission link is powered off. During this period, the data transmission link does not transmit data. Therefore, during the data transmission process, the data transmission link does not need to be powered on all the time, thereby reducing power consumption.

During the data transmission process, the data transmitted during the uplink data transmission and downlink data transmission processes are transmitted through double data rate memory (Double Data Rate, DDR), where DDR is used to cache the data to be transmitted. Therefore, the bandwidth of DDR will limit the efficiency and transmission results of data transmission.

Wherein, both the receiving end 20 and the sending end 10 can be mobile terminals, such as mobile phones (or "cellular" phones) and computers with mobile terminals.

The receiving end 20 and the sending end 10 can also be mobile phones, tablet computers, computers with wireless communication functions, or wearable devices. In the embodiment of the present application, there is no specific limitation on this.

Please refer to FIG. 2 , which shows a flow chart of a data transmission method according to an exemplary embodiment of the present application. The method includes:

Step S201: The terminal determines a target data amount. The target data amount is the data amount transmitted by the uplink data transmission link within a first duration. The first duration is the activation time in the first data transmission cycle of the uplink data transmission link. The corresponding duration of the segment.

The target data amount is the amount of data transmitted by the uplink data transmission link during the activation period of a first data transmission cycle. In some embodiments, each time the terminal performs data transmission, it predicts the amount of data that needs to be transmitted by the uplink data transmission link of this data transmission. In some embodiments, the terminal provides the bandwidth for the uplink data transmission link based on the first duration corresponding to the activation period in the first data transmission cycle of the uplink data transmission link and the bandwidth of the uplink data transmission link provided by the DDR, To determine the maximum amount of data that the uplink data transmission link can transmit in each data transmission cycle.

Correspondingly, in some embodiments, the terminal reads the data amount of data cached in the memory to obtain the target data amount, and the memory is used to cache the data transmitted by the uplink data transmission link within the first duration. When transmitting data through the uplink, the terminal first caches the data to be transmitted in the memory. When the time reaches the start time of the activation period of the first data transmission cycle, the terminal passes the data cached in the memory through the uplink data. Transmission link for data transmission. In this implementation, the terminal determines the target data volume of this 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 transmitted in uplink and downlink data transmission links is affected by the bandwidth of the data transmission link, that is, 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, and the product of the first data parameter bandwidth and the first duration is used as the maximum transmission rate that the uplink data transmission link can transmit within the first duration. Data volume, and use the maximum data volume as the target data volume. In the embodiment of this application, the maximum amount of data that the uplink data transmission link can transmit within the first duration is used as the target data amount. This not only ensures that the uplink data transmission link can also transmit the original data after adjusting the data transmission bandwidth. The maximum amount of data transmitted by the data transmission bandwidth, and there is no need to determine the target data amount for this data transmission during this data transmission, thereby improving the efficiency of data transmission.

It should be noted that the terminal can be a receiving end or a sending end. In the embodiment of the present application, this is not specifically limited.

Step S202: The terminal determines the second duration of the downlink data transmission link, where the second duration is the duration corresponding to the activation time period in the second data transmission cycle of the downlink data transmission link.

The downlink data transmission link is a data transmission link bound to the uplink data transmission link of the terminal. The duration of the second data transmission period and the first data transmission period are the same. The lengths of the first data transmission period and the second data transmission period are set as needed, and are not specifically limited in this 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 cycle, and the second duration is set as needed. In the embodiment of the present application, the second duration is not specifically limited.

In some embodiments, relevant information of the currently used second data transmission cycle is cached in the terminal. The relevant information includes the duration of the second data transmission cycle and the duration corresponding to the activation time period in the second data transmission cycle. Correspondingly, the terminal reads the cached relevant information and obtains the second duration from the relevant information. In some embodiments, the terminal records the duration corresponding to the activation period in the second data transmission cycle through a timer, and stores the activation period locally. When it is necessary to obtain the second duration, the second duration is read from the local storage, or the timing result of the timer is determined as the second duration.

Step S203: Based on the target data amount and the second duration, the terminal adjusts the first data transmission bandwidth of the uplink data transmission link to obtain a second data transmission bandwidth.

The second data transmission bandwidth is smaller than the first data transmission bandwidth. In this step, the terminal adjusts the duration of the activation 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 amount can be within the second duration. Transmission is performed, thus reducing the demand for bandwidth per unit time, thereby adjusting the first data transmission bandwidth to the second data transmission bandwidth, thereby reducing the demand for bandwidth and ensuring the throughput of the data transmission system.

Step S204: Based on the second data transmission bandwidth, the terminal transmits the data to be transmitted through the uplink data transmission link within the activation time period in the second data transmission cycle.

In this step, the terminal sends the data that needs to be transmitted by the uplink data transmission link to other terminals based on the adjusted second data transmission bandwidth and the activation time period in the second data transmission cycle. Correspondingly, the terminal uses the second data transmission bandwidth as the transmission rate and the second duration corresponding to the activation period in the second data transmission cycle as the transmission duration to transmit the data to be transmitted.

Referring to Figure 3, the first data transmission bandwidth of the terminal's uplink data transmission link is Before the first data bandwidth of the road, the data transmission bandwidth of the terminal in the t1 time period is X+Y; the terminal adjusts the data transmission duration of the uplink data transmission link from the first duration to the second duration, and The data transmission bandwidth is adjusted from the first data transmission bandwidth to the second data transmission bandwidth Z, and 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 the t2 time period is Z+Y , the terminal transmits data based on the adjusted data transmission bandwidth and data transmission duration.

Please refer to FIG. 4 , which shows a flow chart of a data transmission method according to an exemplary embodiment of the present application. The method includes:

Step S401: The terminal determines a target data amount. The target data amount is the data amount transmitted by the uplink data transmission link within a first duration. The first duration is the activation time in the first data transmission cycle of the uplink data transmission link. The corresponding duration of the segment.

The principle of this step is the same as that of step S201 and will not be described again.

Step S402: The terminal determines the second duration of the downlink data transmission link, where the second duration is the duration corresponding to the activation time period in the second data transmission cycle of the downlink data transmission link.

The principle of this step is the same as that of step S202 and will not be described again.

Step S403: The terminal determines the target data transmission rate based on the second duration and the target data amount.

The data transmission rate is the ratio of the amount of data transmitted and the transmission duration. Accordingly, in the embodiment of the present application, the terminal determines the quotient of the target data amount and the second duration as the target data transmission rate. In this way, the quotient of the target data amount and the second duration is determined as the target transmission rate. Since the target data amount is the maximum amount of data that the uplink data transmission link can transmit, the quotient of the target data amount and the second duration is determined as data transfer rate, thereby ensuring that data throughput is not affected.

Step S404: The terminal determines the data transmission bandwidth that matches the target data transmission rate as the second data transmission bandwidth.

The data transmission rate is positively related to the data transmission bandwidth. In some embodiments, the value of the terminal target data transmission rate is used as the value of the data transmission bandwidth that matches the target data transmission rate to obtain the second data transmission bandwidth. In some embodiments, based on the target data transmission rate, the terminal determines a second data transmission bandwidth that matches 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 can be determined based on any relationship algorithm between the data transmission rate and the data transmission bandwidth. In the embodiment of the present application, this is not specifically limited.

Step S405: Based on the second data transmission bandwidth, the terminal transmits the data to be transmitted through the uplink data transmission link within the activation time period in the second data transmission cycle.

The principle of this step is the same as that of step S204 and will not be described again.

In some embodiments, the terminal adopts the structure of a modem and a wireless network access point (Access Point, AP). Among them, the modem and AP are connected through a high-speed serial computer expansion bus (Peripheral Component Interconnect Express, PCIE) interface, and the PCIE is powered on through a hardware accelerator to control the activation and sleep of the modem and AP. In order to prevent the waste of power consumption caused by the hardware accelerator keeping the PCIE powered on during the sleep time of the data transmission cycle. This embodiment of the present application proposes to adjust the power-on state of the hardware accelerator based on the data transmission cycle of the downlink data transmission link. See Figure 5, which shows a flow chart of a data transmission method according to an exemplary embodiment of the present application. The method includes:

Step S501: The terminal determines a target data amount. The target data amount is the data amount transmitted by the uplink data transmission link within a first duration. The first duration is the activation time in the first data transmission cycle of the uplink data transmission link. The corresponding duration of the segment.

Step S502: The terminal determines the second duration of the downlink data transmission link, where the second duration is the duration corresponding to the activation time period in the second data transmission cycle of the downlink data transmission link.

Step S503: Based on the target data amount and the second duration, the terminal adjusts the first data transmission bandwidth of the uplink data transmission link to obtain a second data transmission bandwidth.

The principle of this step is the same as that of step S203 and will not be described again.

Step S504: The terminal controls the operating state of the hardware accelerator based on the second data transmission cycle of the downlink data transmission link. The hardware accelerator is used to control the downlink data transmission link and the uplink data transmission link based on the operating state. data transmission.

Referring to Figure 6, in this embodiment of the present application, the duration of the power-on state of the hardware accelerator is consistent with the second data transmission cycle. Before entering the activation period, the terminal wakes up the hardware accelerator to make the hardware accelerator work. During sleep, During this period, the terminal control hardware accelerator also enters the sleep state. Correspondingly, in response to the current time reaching the activation time of the downlink data transmission link, the terminal controls the hardware accelerator to enter the activation state. When the hardware accelerator is in the activation state, the hardware accelerator is used to control the uplink data transmission link and the The downlink data transmission link performs data transmission; in response to the activation duration of the hardware accelerator reaching the second duration, the terminal controls the hardware accelerator to enter a sleep state, and while the hardware accelerator is in a sleep state, the hardware accelerator is used to control the uplink data The transmission link and the downlink data transmission link stop transmitting data.

It should be noted that this step can also be executed before step S201. In the embodiment of the present application, the execution order of this step is not specifically limited.

Step S505: The terminal controls the uplink data transmission link through the hardware accelerator, and based on the second data transmission bandwidth, transmits the data to be transmitted through the uplink data transmission link within the activation period in the second data transmission cycle.

In the embodiment of the present application, by keeping the duration of the power-on state of the hardware accelerator consistent with the second data transmission cycle, the terminal wakes up the hardware accelerator before entering the activation period and causes the hardware accelerator to work during the sleep period. , the terminal controls the hardware accelerator to also enter the sleep state, thereby preventing the uplink and downlink data transmission links from being powered on during the sleep period of the data transmission cycle, thereby saving the terminal's power consumption and further increasing the battery life.
