Description

Data transmission method, device, terminal and storage medium

Technical Field

The present application relates to the field of communications technologies, and in particular, to a data transmission method, apparatus, terminal, and storage medium.

Background

With the rapid development of the communication technology field, in the cellular network, direct communication can be performed between the terminal and the terminal, and the link between the terminal and the terminal is called Sidelink (SL). In a wireless communication network, since a terminal usually uses a battery, in order to prolong the service life of the battery and avoid frequent battery replacement or charging, a DRX mechanism needs to be introduced in a sidelink for the purpose of saving energy.

Data are transmitted between the terminal and the terminal through the SL, and the terminal is used as a data receiver for energy conservation, and the terminal only needs to monitor in partial time period without continuous monitoring. Furthermore, for two data transmission modes present on SL: multicast and broadcast, the DRX configuration information currently has two acquisition modes, one is to acquire the DRX configuration information through a camping cell or a serving cell when the terminal is located within the coverage of the base station, and the other is to use the preconfigured DRX configuration information when the terminal is located outside the coverage of the base station.

At present, because the multicast and broadcast terminals do not establish a connection and do not perform interactive configuration, when some terminals are located in a coverage area and some terminals are located outside the coverage area, DRX configuration information obtained by the terminals may be different, and thus, the two terminals may not be able to communicate.

Referring to fig. 1, fig. 1 is a schematic diagram of an architecture of a data transmission system according to an embodiment of the present application. As shown in fig. 1, the data transmission system includes a network device 110, a first terminal 120, and a second terminal 130. The network device 110 and the first terminal 120 perform data transmission by creating data transmission channels (Uplink, UL) link and downlink), and the first terminal 120 and the second terminal 130 communicate with each other through SL.

Based on the system architecture shown in fig. 1, the first terminal 120 can obtain first DRX configuration information, where the first DRX configuration information is information provided by a first cell, and the first cell is a serving cell or a camped cell of the first terminal; acquiring second DRX configuration information, wherein the second DRX configuration information is information pre-configured in the first terminal, and the first DRX configuration information is different from the second DRX configuration information; if the Reference Signal Received Power (RSRP) of the first cell is smaller than an RSRP threshold, determining third DRX configuration information according to the first DRX configuration information and the second DRX configuration information; and carrying out data transmission according to the third DRX configuration information.

It should be noted that the forms and numbers of the network device 110, the first terminal 120, and the second terminal 130 shown in fig. 1 are only examples, and do not limit the embodiments of the present application.

A data transmission method in the embodiment of the present application is described below with reference to fig. 2A, where fig. 2A is a schematic flow chart of the data transmission method provided in the embodiment of the present application, and the method specifically includes the following steps S101 to S104.

S101, a first terminal acquires first Discontinuous Reception (DRX) configuration information.

The first DRX configuration information is information provided by a first cell, and the first cell is a serving cell or a camped cell of the first terminal.

In addition, the first DRX configuration information is DRX configuration information obtained through system information of the cell when the first terminal is located within a coverage of a base station.

It should be noted that, in the embodiment of the present application, when the first terminal is located within the coverage of the base station, the serving cell or the camping cell of the first terminal provides the first DRX configuration information to the first terminal through the system information to implement configuration of the DRX configuration information of the first terminal.

Further, the system information may include System Information Block (SIB) information.

S102, the first terminal acquires second DRX configuration information.

The second DRX configuration information is information pre-configured in the first terminal, and the first DRX configuration information is different from the second DRX configuration information.

In addition, the second DRX configuration information is DRX configuration information used by the terminal when the first terminal is located outside the coverage of the base station.

It should be noted that, in the embodiment of the present application, it is considered that the serving party configures the second DRX configuration information in the first terminal in advance as needed, and the second DRX configuration information is not specifically limited.

S103, if the Reference Signal Received Power (RSRP) of the first cell is smaller than the RSRP threshold, the first terminal determines third DRX configuration information according to the first DRX configuration information and the second DRX configuration information.

The RSRP threshold is not specifically limited, and a user may set the RSRP threshold according to actual needs.

In a specific implementation, when the reference RSRP of the first cell is smaller than the RSRP threshold, the first terminal is located at the edge of the first cell to which the first terminal belongs, and therefore, other terminals located outside the coverage of the base station and using the second DRX configuration information may exist around the first terminal.

In this example, when the reference RSRP of the first cell of the terminal is smaller than the RSRP threshold, the DRX configuration information determined by the DRX configuration information provided by the cell and the DRX configuration information pre-configured in the first terminal is used to ensure consistency of the DRX configuration information of the sidelink between the terminal and the other terminal in a multicast or broadcast manner.

S104, the first terminal transmits data according to the third DRX configuration information.

Wherein, the data transmission performed by the first terminal according to the third DRX configuration information may be: and the first terminal sends data according to the third DRX configuration information, and/or the first terminal receives data according to the third DRX configuration information.

As can be seen, in this example, the first terminal enables data transmission with other terminals through the DRX configuration information determined by the DRX configuration information provided by the cell and the DRX configuration information pre-configured in the first terminal.

In one possible example, the method further comprises: and if the reference RSRP is greater than or equal to the RSRP threshold value, the first terminal carries out data transmission according to the first DRX configuration information.

The reference RSRP is greater than or equal to the RSRP threshold, that is, when the terminal is within the coverage of the base station and is far from the cell edge, at this time, there is no other terminal located outside the coverage and using the second DRX configuration information around the terminal, and therefore, the terminal may directly use the DRX configuration information provided by the serving cell or the camped cell of the terminal to perform data transmission.

Wherein the first DRX configuration information comprises at least one of a first cycle starting position, a first activation offset, a first DRX cycle, a first activation timer, a first DRX inactivity timer, a first hybrid automatic repeat request round trip delay (HARQ RTT) timer and a first DRX retransmission timer; the second DRX configuration information includes at least one of a second cycle start position, a second activation offset, a second DRX cycle, a second activation timer, a second DRX inactivity timer, a second HARQ RTT timer, and a second DRX retransmission timer.

The cycle start position (DRX-StartOffset) refers to a position where the DRX cycle starts, and is generally expressed in units of subframes (subframes).

The activation offset (drx-SlotOffset) refers to the length of time, typically in slots, that needs to be delayed to start the activation timer.

The DRX cycle (DRX-LongCycle or DRX-ShortCycle) refers to a cycle of mainly configured DRX, including a period of time that needs to be monitored and a period of time that may enter DRX.

An activation timer (DRX-onDurationTimer) determines the period of time for which the DRX cycle needs to be continuously monitored for the beginning.

The DRX inactivity timer (DRX-inactivity timer) determines a period of time to continue monitoring after indicating newly transmitted control signaling.

A Hybrid Automatic Repeat reQuest (HARQ) Round Trip Time (RTT) Timer (drx-HARQ-RTT-Timer) refers to a minimum waiting Time period before HARQ retransmission of the SL is performed.

The DRX retransmission timer (DRX-retransmission timer) determines the longest time period that the terminal needs to monitor before HARQ retransmission of the SL.

In the following, on the premise that the reference RSRP of the serving cell or the camped cell of the first terminal is smaller than the RSRP threshold, the determination methods of various parameters in the multiple types of third DRX configuration information in different scenarios according to the embodiments of the present application are described in detail.

First, a description will be given of a scenario in which the first terminal is a data sender.

For the active time in the third DRX configuration information, the determining, by the first terminal, the third DRX configuration information according to the first DRX configuration information and the second DRX configuration information includes: the first terminal determining a first activation time according to the first cycle start position, the first activation offset, the first DRX cycle, and the first activation timer; the first terminal determines a second activation time according to the second cycle start position, a second activation offset, the second DRX cycle and the second activation timer; the first terminal determines the intersection of the first activation time and the second activation time as a first target activation time; the first terminal determines that the third DRX configuration information includes the first target activation time.

The first activation time is determined by:

if the current subframe number satisfies [ (sfn × 10) + subframe number ] modulo (where modulo is a modulo operation) that the first DRX cycle = the first cycle start position, starting the first activation timer after the first activation offset is postponed from the subframe start position, where the first activation time is a time for which the first activation timer runs.

The second activation time is determined by:

if the current subframe number satisfies [ (sfn × 10) + sfn ] modulo second DRX cycle = second cycle start position, where modulo is modulo operation, the second activation timer is started after the second activation offset is postponed from the subframe start position, and the second activation time is the time for the second activation timer to run.

After determining the first activation time and the second activation time by the first terminal in the above manner, determining an intersection of the first activation time and the second activation time, taking the intersection as the first target activation time, and determining that the third DRX configuration information includes the first target activation time.

For example, please refer to fig. 2B. As the first active time configuration in the first DRX configuration information, if the first DRX configuration information includes a first cycle start position A1-1 (not shown), a first active offset A1-2 (not shown), a first DRX cycle B1 and a first activation timer C1, the first terminal is able to determine a first active stop position D1 of the first DRX cycle B1, and a time from a first activation timer start time A1 (determined by the first cycle start position A1-1 and the first active offset A1-2) to D1 is the first active time. If the second DRX configuration information includes the second cycle start position A2-1, the second activation offset A2-2, the second DRX cycle B2, and the second activation timer C2, the first terminal can determine the second activation stop position D2 of the second DRX cycle B2, and the time from the second activation timer start time A2 (determined by the second cycle start position A2-1 and the second activation offset A2-2) to D2 is the second activation time, as in the second DRX configuration information. When the first terminal is used as a data sender, the first active time in the third DRX configuration information determined by the first terminal is an intersection of the time from A1 to D1 and the time from A2 to D2, and as shown in the figure, the time from A2 to D1 is the first target active time, and it is finally determined that the third DRX configuration information includes the time from A2 to D1.

For the DRX inactivity timer in the third DRX configuration information, the first terminal determines the implementation mode of the third DRX configuration information according to the first DRX configuration information and the second DRX configuration information as follows: the first terminal compares the first DRX inactivity timer with the second DRX inactivity timer, and determines that the DRX inactivity timer with smaller length in the first DRX inactivity timer and the second DRX inactivity timer is a first target DRX inactivity timer; the first terminal determines that the third DRX configuration information includes the first target DRX inactivity timer.

As can be seen, when the reference RSRP of the first cell is smaller than the RSRP threshold, the first terminal sends data by using the DRX inactivity timer provided by the first cell and the DRX inactivity timer preconfigured in the first terminal, and having a smaller length.

For the HARQ RTT timer in the third DRX configuration information, the first terminal determines, according to the first DRX configuration information and the second DRX configuration information, that the implementation manner of the third DRX configuration information is:

the first terminal compares the first HARQ RTT timer with the second HARQ RTT timer to obtain that the HARQ RTT timer with the larger length in the first HARQ RTT timer and the second HARQ RTT timer is a first target HARQ RTT timer; the first terminal determines that the third DRX configuration information includes the first target HARQ RTT timer.

In a specific implementation, when the reference RSRP of the first cell is smaller than the RSRP threshold, the first terminal sends data by using the HARQ RTT timer provided by the first cell and the HARQ RTT timer configured in advance in the first terminal, where the HARQ RTT timer has a larger length.

For example, please refer to fig. 2c, e is the starting position of the HARQ RTT timer. As configured in the first DRX configuration information, G1 is the starting position of the first DRX retransmission timer, and the length of time between E and G1 is the length of the first HARQ RTT timer F1. As configured in the second DRX configuration information, G2 is the starting position of the second DRX retransmission timer, and the length of time between E and G2 is the length of the second HARQ RTT timer F2. Since the length of F1 is greater than the length of F2, if the first terminal is used as the data sender, the configuration in the third DRX configuration information uses F1 with a larger length as the first target HARQ RTT timer, that is, the first target HARQ RTT timer is F1.

For the DRX retransmission timer in the third DRX configuration information, the implementation manner of the first terminal determining the third DRX configuration information according to the first DRX configuration information and the second DRX configuration information may be: the first terminal acquires a first sum of the first DRX retransmission timer and the first HARQ RTT timer; the first terminal acquires a second sum of the second DRX retransmission timer and the second HARQ RTT timer; the first terminal compares the first sum value with the second sum value, and determines the smaller sum value of the first sum value and the second sum value as a first target sum value; the first terminal subtracts the first target HARQ RTT timer from the first target sum value to obtain a first target DRX retransmission timer; the first terminal determines that the third DRX configuration information includes the first target DRX retransmission timer.

For example, please refer to fig. 2c, e is the starting position of the HARQ RTT timer. As configured in the first DRX configuration information, G1 is the starting position of the first DRX retransmission timer, the length of time between E and G1 is the length of the first HARQ RTT timer F1, and the first DRX retransmission timer is H1. As configured in the second DRX configuration information, G2 is the starting position of the second DRX retransmission timer, the length of time between E and G2 is the length of the second HARQ RTT timer F2, and the second DRX retransmission timer is H2. Since the first sum F1+ H1 is greater than the second sum F2+ H2, and the length of F1 is greater than the length of F2, when the first terminal is used as a data sender, the configuration in the third DRX configuration information determines that F1 with a longer length is used as the first target HARQ RTT timer, that is, the length of the first target HARQ RTT timer is F1, and F1 is subtracted from the smaller first target sum F2+ H2 of F1+ H1 and F2+ H2 to obtain the first target DRX retransmission timer H3, it can be understood that in this case, the first terminal uses G1 as the starting position of the first target DRX retransmission timer.

As a possible implementation manner, an implementation manner of the first terminal performing data transmission according to the third DRX configuration information is as follows: and the first terminal sends data according to at least one of the first target activation time, the first target DRX static timer, the first target HARQ RTT timer and the first target DRX retransmission timer.

The most preferable data transmission mode is that the first terminal transmits data according to the first target activation time, the first target DRX inactivity timer, the first target HARQ RTT timer and the first target DRX retransmission timer.

Next, a description will be given of a scenario in which the first terminal is the data receiving side.

For the active time in the third DRX configuration information, the implementation manner of the first terminal determining the third DRX configuration information according to the first DRX configuration information and the second DRX configuration information may be: the first terminal determining a first activation time according to the first cycle start position, the first activation offset, the first DRX cycle, and the first activation timer; the first terminal determines a second activation time according to the second cycle start position, a second activation offset, the second DRX cycle and the second activation timer; the first terminal determines the union set of the first activation time and the second activation time as a second target activation time; the first terminal determines that the third configuration information DRX configuration information includes the second target activation time.

The first activation time is determined by:

if the current subframe number satisfies [ (sfn × 10) + subframe number ] modulo the first DRX cycle = the first cycle start position, where modulo is a modulo operation, the first activation timer is started after the subframe start position delays the first activation offset, and the first activation time is a time for the first activation timer to run.

The second activation time is determined by:

if the current subframe number satisfies [ (sfn × 10) + subframe number ] modulo ] second DRX cycle = second cycle start position, where the modulo is a modulo operation, the second activation timer is started after the second activation offset is postponed from the subframe start position, and the second activation time is a time for the second activation timer to run.

After the first terminal determines the first activation time and the second activation time in the above manner, the first terminal determines a union of the first activation time and the second activation time, takes the union as a second target activation time, and determines that the third DRX configuration information includes the second target activation time.

For example, referring to fig. 2D, as the first active time configuration in the first DRX configuration information, if the first DRX configuration information includes the first cycle start position A1-1 (not shown), the first active offset A1-2 (not shown), the first DRX cycle B1 and the first activation timer C1, the first terminal can determine the first active stop position D1 of the first DRX cycle B1, and the time from the first activation timer start time A1 (determined by the first cycle start position A1-1 and the first active offset A1-2) to D1 is the first active time, and the length of the first active time is equal to C1. And configuring a second active time in the second DRX configuration information, where if the second DRX configuration information includes the second cycle start position A2-1, the second active offset A2-2, the second DRX cycle B2, and the second activation timer C2, the first terminal is able to determine the second active stop position D2 of the second DRX cycle B2, and a time from a second activation timer start time A2 (determined by the second cycle start position A2-1 and the second active offset A2-2) to D2 is the second active time, and at this time, a length of the second active time is equal to a length of C2. When the first terminal is used as a data receiver, the first active time in the third DRX configuration information determined by the first terminal is a union of the time from A1 to D1 and the time from A2 to D2, and the time from A1 to D2 shown in the figure is the second target active time.

For the DRX inactivity timer in the third DRX configuration information, the first terminal determines the implementation mode of the third DRX configuration information according to the first DRX configuration information and the second DRX configuration information as follows: the first terminal compares the first DRX quiescent timer with the second DRX quiescent timer, and determines the DRX quiescent timer with larger length in the first DRX quiescent timer and the second DRX quiescent timer as a second target DRX quiescent timer; the first terminal determines that the third DRX configuration information includes the second target DRX inactivity timer.

In a specific implementation, the first terminal receives data by using the first cell to provide the DRX inactivity timer and the DRX inactivity timer configured in advance in the first terminal, where the DRX inactivity timer has a larger length, when the reference RSRP of the first cell is smaller than the RSRP threshold.

For the HARQ RTT timer in the third DRX configuration information, the first terminal determines, according to the first DRX configuration information and the second DRX configuration information, that the implementation manner of the third DRX configuration information is: the first terminal compares the first HARQ RTT timer with the second HARQ RTT timer to obtain a HARQ RTT timer with a smaller length in the first HARQ RTT timer and the second HARQ RTT timer as a second target HARQ RTT timer; the first terminal determines that the third DRX configuration information includes the second target HARQ RTT timer.

In a specific implementation, the first terminal receives data by using the HARQ RTT timer provided by the first cell and the HARQ RTT timer configured in advance in the first terminal, where the HARQ RTT timer has a smaller length, when the reference RSRP of the first cell is smaller than the RSRP threshold.

For example, please refer to fig. 2E, where E is the starting position of the HARQ RTT timer. As configured in the first DRX configuration information, G1 is the starting position of the first DRX retransmission timer, and the length of time between E and G1 is the length of the first HARQ RTT timer F1. As configured in the second DRX configuration information, G2 is the starting position of the second DRX retransmission timer, and the length of time between E and G2 is the length of the second HARQ RTT timer F2. Since the length of F2 is smaller than the length of F1, if the first terminal is used as the data receiver, the configuration in the third DRX configuration information uses F2 with a smaller length as the second target HARQ RTT timer, in this case, the length of the second target HARQ RTT timer is F2.

For the DRX retransmission timer in the third DRX configuration information, the first terminal determines the implementation mode of the third DRX configuration information according to the first DRX configuration information and the second DRX configuration information as follows:

the first terminal acquires a first sum of the first DRX retransmission timer and the first HARQ RTT timer; the first terminal acquires a second sum of the second DRX retransmission timer and the second HARQ RTT timer; the first terminal compares the first sum value with the second sum value, and determines the larger sum value of the first sum value and the second sum value as a second target sum value; the first terminal subtracts the second target HARQ RTT timer from the second target sum value to obtain a second target DRX retransmission timer; the first terminal determines that the third DRX configuration information includes the second target DRX retransmission timer.

For example, please refer to fig. 2E, where E is the starting position of the HARQ RTT timer. As configured in the first DRX configuration information, G1 is the starting position of the first DRX retransmission timer, the length of time between E and G1 is the length of the first HARQ RTT timer F1, and the first DRX retransmission timer is H1. As configured in the second DRX configuration information, G2 is the starting position of the second DRX retransmission timer, the length of time between E and G2 is the length of the second HARQ RTT timer F2, and the second DRX retransmission timer is H2. Since the first sum F1+ H1 is greater than the second sum F2+ H2, and the second target HARQ RTT timer is F2, if the first terminal is used as the data receiver, the configuration in the third DRX configuration information obtains the second target DRX retransmission timer H4 by subtracting the length of F2 from the larger second target sum F1+ H1 of F1+ H1 and F2+ H2, and it can be understood that in this case, the first terminal uses G2 as the start position of the second target DRX retransmission timer.

As a possible implementation manner, the performing, by the first terminal, data transmission according to the third DRX configuration information includes: and the first terminal receives data by at least one of the second target activation time, the second target DRX inactivity timer, the second target HARQ RTT timer and the second target DRX retransmission timer.

The most preferable data receiving method is that the first terminal receives data according to the second target activation time, the second target DRX static timer, the second target HARQ RTT timer and the second target DRX retransmission timer.
