Description

Data transmission method and device

technical field

The present application relates to communication technology methods, and in particular, to a data transmission method and device.

Background technique

With the development of communication technology, many mobile terminals (such as mobile phones) have dual SIM Dual Standby (DSDS) functions. Among them, dual-card dual-standby means that two subscriber identity module (SIM) cards are installed in a mobile phone at the same time, and the two SIM cards can be on the network standby at the same time.

DSDS mobile phones can be configured with only one set of transceiver radios to save hardware costs. In this way, when the mobile phone is in standby, the two SIM cards in the DSDS mobile phone can monitor paging in time-sharing. However, since the DSDS mobile phone is only equipped with one set of transceiver radio frequency; therefore, the DSDS mobile phone can only realize dual-card dual-standby, but cannot realize dual-card simultaneous communication. However, in practical applications, users have dual-card dual-pass requirements in many scenarios.

As shown in FIG. 1 , the terminal 110 of user A may be the above-mentioned terminal supporting DR-DSDS, and two SIM cards may be installed in the terminal 110 : SIM card 1 and SIM card 2 . After user B uses the terminal 120 to initiate a voice paging request to the SIM card 1 of the terminal 110 , user A can use the terminal 110 to make a voice call with the user B who holds the terminal 120 through the SIM card 1 of the terminal 110 . As shown in FIG. 1 , when user A uses the terminal 110 to conduct a voice call with user B who holds the terminal 120 through the SIM card 1 of the terminal 110, user C may use the terminal 130 to initiate a voice search to the SIM card 2 of the terminal 110. A call request, requesting to conduct a voice call with the user A who holds the terminal 110 through the SIM card 2 of the terminal 110 .

In order to solve the problem that a DSDS mobile phone with only one set of radio frequency transmission and reception cannot be dual-connected, a dual-card uplink DSDS technology is proposed in the prior art. The core idea of this technology is to use the packet scheduling feature of 4G or 5G network services to time-division multiplex the air interface uplink of the data to be sent by the two SIM cards. In addition, when the data to be sent of the two SIM cards collide, the DSDS terminal chooses to first send the data to be sent of one SIM card (taking SIM card 1 as an example), and discard the other SIM card (taking SIM card 2 as an example). Example) of the data to be sent. After that, the DSDS terminal uses the retransmission mechanism to ensure the successful transmission of the data to be sent by the SIM card 2 .

However, based on the retransmission mechanism, after the DSDS mobile phone receives the feedback information returned by the network side, the DSDS mobile phone can only resend the data to be sent by the SIM card 2, resulting in a large delay in sending the data to be sent by the SIM card 2.

Rather, the use of words such as "exemplary" or "such as" is intended to present the related concepts in a specific manner.

The data and the transmission block in the embodiments of the present application have the same meaning and can be replaced with each other, and are described in a unified manner here, and will not be repeated below.

In order to facilitate the understanding of the technical solutions of the present application, the following briefly introduces the technical terms involved in the present application.

1. SIM card

In a mobile communication system, a SIM card can be used as an identifier of a mobile user's network identity. The SIM card is used to store user data and complete user identity authentication. One SIM card corresponds to one mobile user. It should be noted that the SIM card can store the user identity. For example, the subscriber identity may be: an international mobile subscriber identification number (IMSI) or a subscription permanent identifier (SUPI).

SIM cards can be implemented in the form of physical cards, such as standard SIM cards, Mini-SIM cards, Micro SIM cards, and Nano SIM cards. This type of SIM card may also be called a universal subscriber identity module (USIM) card.

The SIM card can also be implemented in the form of a built-in chip, such as an embedded subscriber identity module (embedded-SIM, eSIM) card.

The SIM card can also be implemented in the form of software.

2. Time domain resources

In this embodiment of the present application, the granularity of time domain resources may be a transmission time interval (TTI) in an LTE system, a symbol-level short TTI, or a short TTI with a large subcarrier interval in a high-frequency system , or a radio frame, slot, mini-slot (mini-slot) or an OFDM symbol in the 5G system.

3. HARQ

HARQ is a technology that combines forward error correction (FEC) and automatic repeat request (ARQ) methods. HARQ automatically corrects errors within the range of error correction capabilities. If the error correction range is exceeded, the sender is required to retransmit, which increases system reliability and improves system transmission efficiency.

Among them, FEC means that the data sent by the sender includes forward error correction codes or redundant information. When the receiver receives the data, it passes a check (for example, cyclic redundancy check (CRC)) ) After an error is found, it can be corrected by forward error correction code or redundant information, so that the sender can reduce the number of retransmissions (ie, retransmit data).

ARQ means that the receiving end judges the correctness of the received data by checking (for example, CRC check), if the data is received correctly, the receiving end sends an ACK to inform the sending end, otherwise the receiving end sends a NACK to inform the sending end, and the sending end receives When NACK, the data can be retransmitted to the receiver. ACK and NACK are HARQ feedback.

4. HARQ process

HARQ uses the stop-and-wait protocol to send data. In the stop-and-wait protocol, after the sender sends a transport block (TB), it stops and waits for an acknowledgment. The receiver will use 1-bit information to perform ACK feedback or NACK feedback on the TB. However, the sender stops and waits for an acknowledgment after each transmission, resulting in very low throughput. Therefore, multiple parallel HARQ processes can be used: while one HARQ process is waiting for an acknowledgment, the sender can use another HARQ process to continue sending data.

Exemplarily, the terminal uses the first HARQ process to send TB1, finishes sending TB1 at time T1, receives HARQ feedback from TB1 at time T2, and waits for the confirmation of TB1 during the time period from T1 to T2, and waits for the confirmation of this time. During a period of time, the second HARQ process can be used to send TB2, after sending TB2 at time T2, and receiving HARQ feedback of TB2 at time T3, during the time period from T2 to T3, wait for the confirmation of TB2, and wait for the confirmation of this time. For a period of time, the third HARQ process can be used to send TB3.

It should be noted that each HARQ process can process one TB in one transmission time interval (transmission time interval, TTI). There is a one-to-one correspondence between TB and HARQ processes.

5. Asynchronous HARQ (asynchronous HARQ)

Asynchronous HARQ means that data retransmission can occur at any time, and HARQ processes can be used in any order.

It should be understood that in the case of using asynchronous HARQ, the receiving end does not know the time when the transmission occurs, so the HARQ process ID needs to be sent to the receiving end together with the data.

The advantage of asynchronous HARQ is that retransmission scheduling has greater flexibility.

Currently, the NR system adopts asynchronous HARQ when performing uplink data transmission in a dynamic scheduling manner.

6. Synchronous HARQ (synchronous HARQ)

Synchronous HARQ means that the HARQ process can only retransmit data at a fixed time. With synchronous HARQ, a device can only use a specific HARQ process on a specific subframe.

The advantage of synchronous HARQ is that since the receiving end knows in advance the moment when the transmission occurs, no additional signaling overhead is required to indicate the sequence number of the HARQ process. The HARQ process number can be directly derived from the system frame number/subframe number.

Currently, the LTE system adopts synchronous HARQ in uplink data transmission. The following briefly introduces the synchronous HARQ in the LTE system.

1) Frequency Division Duplexing (FDD)-LTE

For the FDD-LTE system, if the UE receives an uplink grant (UL grant) or a physical hybrid ARQ indicator channel (PHICH) in subframe n, the UE will Send the physical uplink shared channel (PUSCH). The PUSCH is used to carry uplink data.

For the FDD-LTE system, if the UE receives a PHICH in subframe n, the PHICH corresponds to the PUSCH sent by the UE in subframe n-4.

2) Time Division Duplexing (TDD)-LTE

For TDD UL/DL configurations 1 to 6, if the UE receives a UL grant or PHICH in subframe n (only NACK is received), the UE will send the corresponding PUSCH in n+k1 subframe. Exemplarily, the value of k1 can be determined according to Table 1 below.

Table 1

Exemplarily, taking the TDD UL/DL Configuration as 1 as an example, assuming that the UE receives the UL grant in subframe 1, the UE shall send the corresponding PUSCH in subframe 7.

For TDD UL/DL configurations 1 to 6, if the UE receives a PHICH in subframe n, the PHICH corresponds to the PUSCH sent on subframe n-k2. Exemplarily, the value of K2 can be determined according to Table 2 below.

Table 2

The above is an introduction to the terms involved in the embodiments of the present application, which are uniformly described here, and will not be repeated below.

Currently, when the data of the two SIM cards collide in the time domain, the DSDS terminal chooses to send the data of one SIM card first, and discard the data of the other SIM card. After that, the DSDS terminal reuses the retransmission mechanism to retransmit the discarded data.

Exemplarily, as shown in FIG. 2( a ), the time slot #14 occupied by data 3 and the time slot #17 occupied by data 6 overlap in the time domain, so the data 3 of the SIM card 2 and the data 6 of the SIM card 1 overlap in the time domain. conflict in the time domain. After arbitration, the terminal decides to send the data packet 6 of the SIM card 1 and discard the data packet 3 of the SIM card 2 . After that, the terminal can only retransmit the data packet 3 of the SIM card 2 after receiving the feedback information from the network device.

However, the transmission delay caused by the retransmission mechanism is relatively large. Moreover, the higher the level of the network protocol that initiates retransmission, the greater the retransmission delay and data load, which degrades the user experience. As shown in Figure 2(b), the delay time of physical layer retransmission reaches the millisecond level; the delay time of MAC layer retransmission reaches hundreds of milliseconds level; the high-level protocol layer (that is, the protocol layer above the MAC layer, such as the RRC layer) ) The delay time of retransmission reaches the second level.

It can be seen that, for the DSDS terminal, in the scenario where the data of the two SIM cards collide in the time domain, there are problems of high data retransmission rate and large transmission delay.

In order to solve the above technical problem, an embodiment of the present application provides a data transmission method, which is applied to a terminal configured with multiple SIM cards. The technical idea of the data transmission method is: when the data of SIM card 1 and the data of SIM card 2 conflict in the time domain, the terminal can send the data of SIM card 1 preferentially and send the data of SIM2 later. In this way, the terminal does not need to wait for the feedback information of the data of the SIM card 2 from the network device, and can flexibly adjust the sending time of the data of the SIM card 2, so that the data of the SIM card can be transmitted as soon as possible and reduce the data transmission delay.

For convenience of description, the technical solution in the prior art is hereinafter referred to as a "retransmission sending mode", and the technical solution provided by the embodiments of the present application is referred to as a "delayed sending mode".

Optionally, in order to pursue higher transmission performance, the "delayed sending mode" can be adopted for the data of any service.

Optionally, in order to take into account the balance between transmission performance and complexity, the data of the first type of service adopts the "retransmission and transmission mode", and the data of the second type of service adopts the "delayed transmission mode".

Exemplarily, the first type of service refers to a service that does not have high requirements for implementation, such as a file transfer service and the like.

Exemplarily, the second type of service refers to a service with high implementation requirements, such as a voice call service, a video session service, and the like. Therefore, the data of the second type of service is the data requiring the transmission delay to be less than the first value, and/or the data requiring the packet loss rate to be less than the second value.

As shown in FIG. 3 , the terminal 200 may include: a first SIM card interface 210 , a second SIM card interface 220 , a manager 240 respectively coupled to the first SIM card interface 210 and the second SIM card interface 220 , and the manager 240 The processor 230 is coupled, and the processor 230 is connected to the transceiver 250 .

The above-mentioned first SIM card interface 210 is used for installing the SIM card 1 and communicating with the SIM card 1 , and the above-mentioned second SIM card interface 220 is used for installing the SIM card 2 and communicating with the SIM card 2 .

Exemplarily, each SIM card configured in the terminal in the embodiment of the present application may be a system supporting a Global System for Mobile Communication (GSM) standard, a Universal Mobile Telecommunications System (UMTS) standard, Time Division Synchronous Code Division Multiple Access (TD-SCDMA) system, Long Term Evolution (Long Term Evolution, LTE) system, Code Division Multiple Access (Code Division Multiple Access, CDMA) system and other standards Any kind of SIM card.

Optionally, only two SIM card interfaces are shown in FIG. 3 above, and the terminal 200 may also be configured with more SIM card interfaces.

It should be noted that the radio frequency Tx path in this embodiment of the present invention may also be referred to as a Tx radio frequency resource or a transmitter (transmitter), and the radio frequency Rx path may also be referred to as an Rx radio frequency resource or a receiver (Receiver).

Wherein, in the embodiment of the present invention, the above-mentioned radio frequency Tx channel and radio frequency Rx1 channel may also be referred to as an RF main channel, and the above-mentioned radio frequency Rx2 channel may be referred to as an RF sub-channel. That is, the uplink and downlink RF devices (such as the radio frequency Tx channel and the radio frequency Rx1 channel) in the RF main channel are multiplexed, and the RF secondary channel has only the downlink RF devices (such as the radio frequency Rx2 channel).

FIG. 4 shows a schematic diagram of a communication system provided by an embodiment of the present application. As shown in FIG. 4 , the terminal 200 can install at least two SIM cards, such as a first SIM card and a second SIM card. The first SIM card in the terminal 200 may be the main card of the terminal 200, and the second SIM card may be the secondary card of the terminal 200; or, the second SIM card in the terminal 200 may be the main card of the terminal 200, and the first SIM card It can be a secondary card of the terminal 200 .

The terminal 200 may establish a wireless connection with the first network device 300 using the first SIM card. In this way, the terminal 200 and the first network device 300 can mutually transmit the data of the first SIM card.

Correspondingly, the terminal 200 may use the second SIM card to establish a wireless connection with the second network device 400 . In this way, the terminal 200 and the network device 400 can mutually transmit the data of the SIM card 2 .

The above-mentioned first network device 300 and second network device 400 may be the same network device or different network devices. It should be understood that the second network device 300 and the first network device 400 may be the same network device, or may be different network devices. For example, if the first SIM card and the second SIM card belong to the same operator and support the same network standard, the first network device 300 and the second network device 400 may be the same network device. For another example, if the first SIM card and the second SIM card do not belong to the same operator, the first network device 300 and the second network device 400 are not the same network device. The embodiments of the present application are uniformly described here, and will not be repeated below.

The above-mentioned network device may be a base station or a base station controller for wireless communication. For example, the base station may include various types of base stations, such as a micro base station (also referred to as a small cell), a macro base station, a relay station, an access point, etc., which are not specifically limited in this embodiment of the present application. In the embodiment of the present application, the base station may be an evolutional node B (evolutional node B, eNB or e-NodeB) in long term evolution (long term evolution, LTE), an internet of things (internet of things, IoT) or a narrowband thing The eNB in the Internet of Things (narrow band-internet of things, NB-IoT), the base station in the future 5G mobile communication network or the future evolution of the public land mobile network (public land mobile network, PLMN), the embodiment of this application does not make any limit. In this embodiment of the present application, the apparatus for implementing the function of the network device may be the network device, or may be an apparatus capable of supporting the network device to implement the function, such as a chip system. In the embodiments of the present application, the technical solutions provided by the embodiments of the present application are described by taking the apparatus for implementing the functions of the network equipment as the network equipment as an example.

The network equipment mentioned in this application, such as a base station, generally includes a baseband unit (baseband unit, BBU), a remote radio unit (remote radio unit, RRU), an antenna, and a feeder for connecting the RRU and the antenna. Among them, the BBU is used for signal modulation. The RRU is responsible for radio frequency processing. The antenna is responsible for the conversion between the guided traveling waves on the cable and the space waves in the air. On the one hand, the distributed base station greatly shortens the length of the feeder between the RRU and the antenna, which can reduce the signal loss and the cost of the feeder. On the other hand, the RRU plus antenna is relatively small and can be installed anywhere, making network planning more flexible. In addition to the remote RRU, all BBUs can also be centralized and placed in the central office (CO). Through this centralized method, the number of base station computer rooms can be greatly reduced, and supporting equipment, especially air conditioners, can be reduced. Energy consumption can reduce a lot of carbon emissions. In addition, after the scattered BBUs are integrated into a BBU baseband pool, they can be managed and scheduled in a unified manner, and resource allocation is more flexible. In this mode, all physical base stations have evolved into virtual base stations. All virtual base stations share the user's data transmission and reception, channel quality and other information in the BBU baseband pool, and cooperate with each other to realize joint scheduling.

In some deployments, a base station may include a centralized unit (CU) and a distributed unit (DU). The base station may also include an active antenna unit (AAU). The CU implements some functions of the base station, and the DU implements some functions of the base station. For example, the CU is responsible for processing non-real-time protocols and services, and implementing functions of radio resource control (RRC) and packet data convergence protocol (PDCP) layers. The DU is responsible for processing physical layer protocols and real-time services, and implementing functions of the radio link control (RLC), media access control (MAC), and physical (PHY) layers. AAU implements some physical layer processing functions, radio frequency processing and related functions of active antennas. Since the information of the RRC layer will eventually become the information of the PHY layer, or be transformed from the information of the PHY layer, therefore, under this architecture, higher-layer signaling, such as RRC layer signaling or PDCP layer signaling, can also It is considered to be sent by DU, or, sent by DU+AAU.

As shown in FIG. 6 , a data transmission method provided in an embodiment of the present application is applied to a terminal configured with multiple SIM cards, and the method includes the following steps:

S101. The terminal determines that the first time domain resource and the second time domain resource overlap in the time domain.

The first time domain resource is a time domain resource that is scheduled to send the first data of the first SIM card. The second time domain resource is a time domain resource scheduled to transmit the second data of the second SIM card.

It should be understood that the first time domain resource and the second time domain resource overlap in the time domain, which may be: the first time domain resource and the second time domain resource overlap partially or completely in the time domain.

Optionally, when the data of the two SIM cards collide in the time domain, the terminal can determine, according to the data priorities of the two SIM cards, that the data with high priority is obtained for transmission authorization, and the data with low priority is not authorized. Obtained transmission authorization. It should be understood that the data that has obtained the transmission authorization can be sent normally.

It should be understood that the priority of the data may be determined according to factors such as the quality of service required by the data, the service type of the data, and the like, which is not specifically limited in this embodiment of the present application. For example, the priority of the data of the voice service may be higher than that of the data of the file transfer service.

Exemplarily, the processing of the first data and the second data by the terminal will be specifically described below by taking the acquisition of the first data and the transmission authorization as an example.

S102. The terminal sends the first data of the first SIM card in the first time domain resource.

Optionally, the first data may be carried on the first PUSCH.

S103. The terminal sends the second data on the third time domain resource.

Wherein, the third time domain resource is a time domain resource scheduled for sending the third data of the second SIM card. It should be understood that the third data is different from the second data.

In this embodiment of the present application, the third time domain resource is located after the second time domain resource. For example, if the time-domain resources have symbol granularity, the third time-domain resources are located after the second time-domain resources, specifically, the start symbol of the third time-domain resources is located after the end symbols of the second time-domain resources. For another example, taking the time domain resource as the subframe as the granularity, the third time domain resource is located after the second time domain resource, specifically: the subframe occupied by the third time domain resource is located in the subframe occupied by the second time domain resource frame after.

Optionally, when the communication system accessed by the second SIM card adopts synchronous HARQ during uplink data transmission, the time interval between the third time domain resource and the second time domain resource is smaller than the second time domain resource and The time interval between resources in the fourth time domain. The above-mentioned fourth time domain resource refers to the time domain resource occupied by the data sent on the second time domain resource during retransmission.

It should be understood that in the case of synchronous HARQ, the time interval between the second time domain resource and the fourth time domain resource is a first preset value.

In the LTE system, the time interval between two time domain resources can be expressed by the difference between the subframe numbers of the two time domain resources.

Taking the FDD-LTE system as an example, the difference between the subframe number of the second time domain resource and the subframe number of the fourth time domain resource is 8. For example, the second time domain resource is subframe 1, and the fourth time domain resource is subframe 9.

Taking the TDD-LTE system as an example, the difference between the subframe number of the second time domain resource and the subframe number of the fourth time domain resource may be k1+k2. Wherein, k1 is the difference between the subframe number of the second time domain resource and the subframe number of the time domain resource carrying the feedback information. K2 is the difference between the subframe number of the time domain resource carrying the feedback information and the subframe number of the fourth time domain resource. Exemplarily, reference may be made to Table 1 for the manner of determining k1. For the determination method of k2, please refer to Table 2.

In this embodiment of the present application, the third time domain resource does not overlap with the first time domain resource. In other words, the third time domain resource is after the first time domain resource. In this way, it is avoided that the second data and the first data conflict again in the time domain, so that the terminal needs to reschedule time domain resources for the second data.

Optionally, the second data may be carried on the second PUSCH. The second PUSCH is different from the first PUSCH.

The embodiment shown in FIG. 6 is illustrated by an example. As shown in FIG. 7 , in the case where the data 3 of the SIM card 2 and the data 5 of the SIM card 1 conflict in the time domain, the terminal sends the SIM card first after arbitration. Data 5 of card 1, and data 3 of SIM card 2 are scheduled to be sent on time slot #16.

Based on the embodiment shown in FIG. 6 , in a scenario where the data of the two SIMs collide in the time domain, the terminal stores the first data of the first SIM card in the originally scheduled time domain resource (that is, the first time domain resource). ), and the second data of the second SIM card is delayed to be sent on the third time domain resource. That is, the terminal may send the second data of the second SIM card before receiving the feedback information of the second data. In this way, the terminal can reduce the delay in sending the second data of the second SIM card.

In this embodiment of the present application, the uplink data transmission of the terminal may be based on a "request-grant" transmission mechanism, or an uplink dynamic authorization-free transmission mechanism.

Among them, the "request-grant" transmission mechanism may also be referred to as a dynamic scheduling mechanism. The "request-grant" transmission mechanism is specifically: when the terminal has data to transmit, the terminal dynamically applies to the network for uplink resources, so that the terminal can perform data transmission on the uplink resources allocated by the network device.

The uplink dynamic grant-free transmission mechanism can also be called a semi-persistent scheduling mechanism. The uplink dynamic authorization-free transmission mechanism is specifically as follows: after the terminal and the network device establish an RRC wireless connection, the network device can specifically allocate and configure authorization resources for the terminal. After that, when the terminal has data that needs to be transmitted, the terminal can directly use the configuration authorization resource to send the data.

It should be understood that, compared with the uplink dynamic grant-free transmission mechanism, the "request-grant" transmission mechanism is more flexible. Compared with the "request-grant" transmission mechanism, the data transmission delay of the uplink free dynamic authorization transmission mechanism is lower.

Optionally, for the first data of the first SIM card, in the case of adopting the uplink dynamic authorization-free transmission mechanism, based on the embodiment shown in FIG. 6, as shown in FIG. 8(a), the data transmission method is in step Step S201 is also included before S101.

S201. The terminal receives first configuration information sent by a first network device.

Wherein, the first configuration information may be used to configure a first configuration authorization time domain resource for the terminal. It should be understood that the first configuration authorization time domain resource is related to the first SIM card. The first configuration authorizes the time domain resource to be used for transmitting data of the first SIM card, for example, the above-mentioned first data.

Optionally, the first configuration information can also be used to configure other transmission parameters used in uplink dynamic authorization-free transmission for the terminal, such as open-loop power control related parameters, waveform, redundancy version sequence, repetition times, frequency hopping mode, resource Allocation type, number of HARQ processes, DMRS related parameters, MCS table, Resource Block Group (RBG) size, frequency domain resources, and MCS.

Optionally, the first configuration information may be carried in RRC signaling or in DCI signaling, which is not limited in this embodiment of the present application.

Based on the embodiment shown in FIG. 8( a ), the terminal may determine the time domain resource authorized by the first configuration according to the first configuration information. Furthermore, the terminal may authorize the time domain resource according to the first configuration, and determine the first time domain resource. It should be understood that the first time domain resource is a part or all of the time domain resources authorized by the first configuration.

Optionally, for the first data of the first SIM card, in the case of adopting the "request-authorization" mechanism, based on the embodiment shown in FIG. 6, as shown in FIG. 8(b), the data transmission method is in step Before S101, steps S301-S302 are further included.

Exemplarily, taking the communication system as an LTE system as an example, assuming that the time domain resource is a subframe, the subframe number Q1 of the first time domain resource is determined according to the subframe number n1 of the time domain resource carrying the first scheduling information. For example, Q1=n1+m1.

Exemplarily, taking the communication system as an LTE system as an example, assuming that the time domain resource is a subframe, the subframe number Q3 of the third time domain resource is determined according to the subframe number n3 of the time domain resource carrying the third scheduling information. For example, Q3=n3+m3.

In the FDD-LTE system, m3=4. In the TDD-LTE system, m3 can be determined according to the TDD UL/DL configuration and n2. The TDD UL/DL configuration is configured by the network side to the terminal.

Based on the second scenario, the third scheduling information includes configuration information of the third time domain resource. Exemplarily, the configuration information of the third time domain resource is used to indicate the following parameters: a slot offset value, a start symbol of the third time domain resource, a symbol length of the third time domain resource, and the like. The time slot offset value included in the configuration information of the third time domain resource is used to determine the time slot where the third time domain resource is located.

In this way, the terminal can determine the second time domain resource according to the configuration information of the third time domain resource included in the third scheduling information.

Optionally, the third scheduling information may further include a process ID of the third HARQ process. The third HARQ process is the HARQ process used to transmit the third data in the HARQ entity corresponding to the second SIM card.

Optionally, the third HARQ process is different from the second HARQ process.

Based on the embodiment shown in FIG. 9( c ), the terminal may determine the third time domain resource according to the third scheduling information. Further, the terminal may also determine a HARQ process for transmitting the third data in the second SIM card.

Optionally, before step S103, the terminal needs to schedule the second data. The scheduling method of the terminal may be the rescheduling method of the physical layer or the rescheduling method of the MAC layer.

Optionally, taking the rescheduling manner of the physical layer as an example, based on the embodiment shown in FIG. 6 , as shown in FIG. 10 , the data transmission method further includes steps S701 to S702 before step S103 .

S701. The physical layer of the terminal sends first indication information to the MAC layer of the terminal.

The first indication information is used to instruct the MAC layer to temporarily stop scheduling of data. In this way, the conflict between the data scheduling of the MAC layer and step S702 is avoided.

In this embodiment of the present application, the above-mentioned physical layer and MAC layer belong to a protocol stack corresponding to the second SIM card.

S702. The physical layer of the terminal buffers the second data stored in the storage area of the second HARQ process into the storage area of the third HARQ process.

Correspondingly, step S103 in FIG. 6 can be specifically implemented as step S703 in FIG. 10 .

S703. The terminal uses the third HARQ process to send the second data on the third time domain resource.

Based on the embodiment shown in FIG. 10 , in a scenario where the data of two SIM cards collide in the time domain, the terminal delays sending the second data of the second SIM card by means of physical layer rescheduling, which is beneficial to reduce collision and collision , and reduce the sending delay of the second data.

The embodiment shown in FIG. 10 is explained by way of example. As shown in FIG. 11 , it is assumed that the terminal uses SIM card 1 to access the NR system of the first operator, and the terminal uses SIM card 2 to access the NR system of the second operator. Among them, the NR system of the first operator schedules the data 6 of the SIM card 1 of the terminal to be transmitted in time slot #15 to time slot #17, and the NR system of the second operator schedules the data 3 of the SIM card 2 of the terminal at time slot #15 to time slot #17 transmission on slot #14. It can be seen that the data 3 of the SIM card 2 and the data 6 of the SIM card 1 conflict in the time domain. After arbitration, the terminal decides to delay sending the data 3 of the SIM card 2 . Therefore, in the protocol stack corresponding to the SIM card 2, the HARQ entity in the physical layer of the terminal sends the first indication information to the MAC layer, and blocks the MAC layer to schedule new data packets. After that, the HARQ entity buffers data 3 into the storage area of any one of the multiple HARQ processes (HARQ0-HARQ3 in FIG. 11 ) corresponding to time slot #16, so that data 3 can be sent on time slot #16 .

Optionally, taking the rescheduling manner of the MAC layer as an example, based on the embodiment shown in FIG. 6 , as shown in FIG. 12 , the data transmission method further includes steps S801 to S804 before step S103 .

S801. The physical layer of the terminal sends a serial number (serial number, SN) of the second data to the MAC layer of the terminal.

S802. The MAC layer of the terminal searches for the second data from the data buffer area of the MAC layer according to the sequence number of the second data.

S803. The MAC layer of the terminal sends the second data to the physical layer of the terminal.

S804. The physical layer of the terminal stores the second data in the storage area of the third HARQ process.

Correspondingly, step S103 in FIG. 6 may be embodied as step S805 in FIG. 12 .

S805. The terminal uses the third HARQ process to send the second data on the third time domain resource.

Based on the embodiment shown in FIG. 12 , in a scenario where the data of two SIM cards collide in the time domain, the terminal delays sending the second data of the second SIM card by means of MAC layer rescheduling, which is beneficial to reduce the collision and collision , and reduce the sending delay of the second data.

The embodiment shown in FIG. 12 is described by way of example. As shown in FIG. 13 , it is assumed that the terminal uses SIM card 1 to access the NR system of the first operator, and the terminal uses SIM card 2 to access the NR system of the second operator. Among them, the NR system of the first operator schedules the data 6 of the SIM card 1 of the terminal to be transmitted in time slot #15 to time slot #17, and the NR system of the second operator schedules the data 3 of the SIM card 2 of the terminal at time slot #15 to time slot #17 transmission on slot #14. It can be seen that the data 3 of the SIM card 2 and the data 6 of the SIM card 1 conflict in the time domain. After arbitration, the terminal decides to delay sending the data 3 of the SIM card 2 . Therefore, in the protocol stack corresponding to SIM card 2, the HARQ entity of the physical layer of the terminal sends the serial number of data 3 to the MAC layer, and the MAC layer finds the data 3 from the data buffer area of the MAC layer, and reschedules the time slot# 14. Data 3 that cannot be sent is buffered in the storage area of any one of the multiple HARQ processes (HARQ0-HARQ3 in FIG. 13) corresponding to time slot #16, so that data 3 can be stored at the time slot #16. sent on slot #16.

At present, due to the uncertainty of the uplink transmission of the terminal, the data of one SIM card may conflict with the data of other SIM cards in the time domain for many times, and the data of the SIM card may not obtain the transmission authorization, resulting in the The data of the SIM card cannot be transmitted for a long time, which increases the transmission delay of the data of the SIM card. In addition, the data of the SIM card cannot be transmitted for a long time, which will also cause the terminal to have a large backlog of data to be sent, so that the terminal needs a large buffer space to store the data to be sent.

In order to solve this technical problem, the embodiments of the present application provide the following technical solutions:

One technical solution

As shown in FIG. 14 , a data transmission method provided by an embodiment of the present application includes the following steps:

S901. The terminal determines that the target data of the target SIM card meets a preset condition.

The target SIM card may be any one of multiple SIM cards configured in the terminal.

Exemplarily, the preset condition is: when the target data of the target SIM card conflicts with the data of other SIM cards in the time domain, the target data of the target SIM card has not obtained the transmission authorization.

Optionally, the conflict between the target data of the target SIM card and the data of other SIM cards in the time domain may refer to: the time domain resources scheduled to send the target data of the target SIM card and the time domain resources scheduled to send other SIM cards. The time domain resources of the data of the card overlap in the time domain.

Optionally, the target data of the target SIM card has not obtained the transmission authorization, which may be because: the priority of the target data of the target SIM card is lower than the priority of the data of other SIM cards.

S902, the terminal increases the priority of the target data of the target SIM card.

As a possible implementation manner, the terminal increases the priority of the target data of the target SIM card from the first priority to the second priority. The difference between the second priority and the first priority may be fixed or dynamically changed.

Based on the embodiment shown in FIG. 14 , after the target data of the target SIM card conflicts with the data of other SIM cards in the time domain, the terminal increases the priority of the target data of the target SIM card to improve the target data of the target SIM card. The probability that the data will get the transmission authorization on the next collision. It can be seen that the technical solution of the present application can alleviate the problem that the target data of the target SIM card cannot be transmitted for a long time, thereby reducing the transmission time delay of the target data of the target SIM card. In addition, the technical solution of the present application also makes it unnecessary for the terminal to buffer more data to be sent, so as to save the buffer space of the terminal.

technical solution two,

As shown in FIG. 15 , a data transmission method provided by an embodiment of the present application includes the following steps:

S1001. The terminal obtains the number of times that the target data of the target SIM card meets a preset condition.

As a possible implementation manner, when the target data of the target SIM card meets the preset condition for the first time, the terminal sets a corresponding counter for the target data of the target SIM card, and sets the count value of the counter to 1. After that, whenever the target data of the target SIM card satisfies the preset condition once, the terminal adds 1 to the counter corresponding to the target data of the target SIM card.

S1002. When the number of times that the target data of the target SIM card meets the preset condition is greater than or equal to a second preset value, the terminal sends the target data of the target SIM card.

The second preset value may be configured by the network device to the terminal, or may be determined by the terminal itself.

As a possible implementation, when the number of times that the target data of the target SIM card satisfies the preset condition is greater than or equal to the second preset value, no matter whether the target data of the target SIM card conflicts with the data of other SIMs in the time domain , the terminals all send the target data of the target SIM card.

Based on the embodiment shown in FIG. 15 , when the number of times that the target data of the target SIM card satisfies the preset condition is greater than or equal to the second preset value, the terminal compulsorily sends the target data of the target SIM card to avoid the The target data cannot get a transmission opportunity because it collides with the data of other SIM cards in the time domain. That is, the technical solution of the present application can alleviate the problem that the target data of the target SIM card cannot be transmitted for a long time, thereby reducing the transmission delay of the target data of the target SIM card. In addition, the technical solution of the present application also makes it unnecessary for the terminal to buffer more data to be sent, so as to save the buffer space of the terminal.
