In order to better understand the solutions provided by the embodiments of the present disclosure, the related technologies related to the embodiments of the present disclosure will be described first.

1) Configuration authorization: CG (configured grant)

Instead of allocating radio resources once per slot/TTI to a UE (specified via PDCCH) when dynamically scheduled, the configuration grant allows semi-static configuration of radio resources and periodic allocation of the resources to a particular UE.

In short, the network side notifies the UE that a certain resource can be used periodically, and optionally, the location of the periodic resource may be notified through RRC signaling. Optionally, the network side may further notify the UE of information such as frequency domain location, start/stop time, and MCS of the used resource. In this way, the network reduces PDCCH notification overhead through periodic resource allocation.

And configuring an authorization scheduling mode, which is suitable for periodic services, such as VoIP, or services with periodic control signaling in some URLLC services.

The configuration grant is an uplink scheduling manner. There are two ways of type1 and type 2.

In Type 1: the RRC allocates periodic resources, and after the RRC is configured, the resources are in an activated state, namely the UE can use the resources to send uplink data after receiving the RRC configuration message;

in Type2, the RRC allocates periodic resources, but the initial state is inactive, the network side needs to activate the resources through physical layer signaling, and after data transmission is finished, the resources are deactivated through DCI. Similarly, the configuration information of the partial configuration grant, such as modifying the time-frequency domain location information of the resource, may also be modified through physical layer signaling.

2) Logical channel priority comparison

If the UE is configured with priority comparison of overlapping resources, namely when the configuration authorization and the dynamic authorization or the configuration authorization resources overlap in time, the UE compares the priorities and judges which authorization is transmitted preferentially according to the priority. The process of the UE comparing the priorities means that the UE compares the priorities of the two grants. The authorized priority refers to the highest priority among the data that has been multiplexed or the logical channels that will have multiplexed data.

Or when the configuration authorization collides with the SR resource, the UE compares the priority level and judges that the configuration authorization or the SR resource is transmitted preferentially according to the priority level. The process of comparing the priorities by the UE means that the UE compares the priorities of the configured authorized resources, that is, the highest priority among the priorities of the data already multiplexed or the logical channels to be multiplexed, and the SR priority means the priority of the logical channel triggering the SR.

When the configuration authorization is prioritized down, if the MAC layer has generated a data packet, the UE stores the data packet in the MAC entity, and the UE may automatically retransmit or wait for network-side retransmission scheduling. When the network side configures automatic transmission (autonomous transmission), the UE may perform a new transmission using the next available configuration grant.

3)LBT(listen before talk)

LBT is a physical layer sounding technique used in unlicensed spectrum, and a device may determine whether a channel is occupied by listening. When the device detects that the channel is busy before transmitting data, the device stops data transmission until the channel is free. The device detects that the channel is busy, which may also be referred to as receiving an LBT failure indication.

The network side configures a plurality of configuration authorizations for the UE, and a plurality of priorities exist in a logical channel which can be multiplexed to the configuration authorizations, namely high-priority data or low-priority data.

As shown in fig. 1, at time T1, HP # N multiplexes only lower priority data, but due to LBT failure, the UE needs to retransmit the data of HP # N, and the UE can select T2 to configure the grant on grant # 2. However, T2 has data with higher priority to arrive, and if the retransmission data is transmitted by priority at this time, the T2 data cannot be transmitted, which results in an increased delay.

On the other hand, in the TSN network, in order to avoid overcoming the delay jitter, the network side configures multiple sets of configuration grants, and when data jitter occurs, the UE may continue to transmit the data at the next configuration grant time. As shown in fig. 2, the priorities of multiple sets of configuration authorization data multiplexed here are the same, data packet 3 (HP # 1) cannot be sent in the previous CG period due to LBT failure or priority reduction, and can only be sent in the next CG period, in order to ensure that retransmission delay can only be selected to perform retransmission in CG #1, and at this time, a new data packet arrives, then the UE can only send on CG # 2.

In the above scenario, the judgment sequences for new transmission and retransmission are different, which causes different final data delay influences, and all schemes need to be formulated to solve the above problems.

The data transmission method, device and storage medium provided by the embodiments of the present disclosure aim to solve the above technical problems in the prior art.

The following describes in detail the technical solutions of the embodiments of the present disclosure and how to solve the above technical problems with specific embodiments. The several embodiments may be combined, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the disclosed embodiments will be described below with reference to the accompanying drawings.

The data transmission method provided by the embodiment of the disclosure can be applied to the application environment shown in fig. 3. Fig. 3 includes a base station 301 and a terminal 302, where the base station 301 sends configuration information to the terminal 302, and the terminal 302 performs data transmission based on the configuration information in the following manner: performing data retransmission by using a configuration authorization mode; and if the authorization of the newly transmitted data conflicts with the authorization of the retransmitted data, determining the characteristics of the configuration authorization respectively corresponding to the retransmitted data and the newly transmitted data, and transmitting the retransmitted data or the newly transmitted data based on the characteristics of the configuration authorization.

A possible implementation manner is provided in the embodiment of the present disclosure, as shown in fig. 4, a data transmission method is provided, which is described by taking the application of the method to the terminal in fig. 3 as an example, and may include the following steps:

step S401, a configuration authorization mode is used for data new transmission;

step S402, if the authorization of the newly transmitted data conflicts with the authorization of the retransmitted data, the characteristics of the configuration authorization respectively corresponding to the retransmitted data and the newly transmitted data are determined, and the retransmitted data or the newly transmitted data are transmitted based on the characteristics of the configuration authorization.

Wherein the feature of the configuration authorization may include at least one of: and configuring the priority corresponding to the logic channel of the authorized bearer.

Specifically, the retransmission data may be retransmitted based on any one of the following manners:

performing retransmission based on network equipment scheduling;

the terminal carries out autonomous retransmission according to the priority of newly transmitted data;

In a specific implementation process, the new data authorization conflicts with the retransmission data authorization, that is, the retransmission data authorization collides with the new data authorization, a transmission sequence of the retransmission data and the new data, that is, whether the retransmission data is preferentially transmitted or the new data is transmitted can be determined according to characteristics of configuration authorization corresponding to the retransmission data and the new data, and the retransmission data and the new data are transmitted based on the transmission sequence.

In the above embodiment, when the authorization of the newly transmitted data conflicts with the authorization of the retransmitted data, the terminal may determine whether to preferentially transmit the newly transmitted data or the retransmitted data, so as to ensure the delay reliability of the service.

A possible implementation manner is provided in the embodiment of the present disclosure, the step S402 determines features of configuration authorization respectively corresponding to the retransmitted data and the newly transmitted data, and the transmitting the retransmitted data or the newly transmitted data based on the features of configuration authorization may include:

a. determining the characteristic of a first configuration authorization corresponding to the retransmission data, and determining the characteristic of a second configuration authorization corresponding to the newly transmitted data;

b. determining the transmission sequence of the retransmitted data and the newly transmitted data based on the characteristics of the first configuration authorization and the characteristics of the second configuration authorization;

c. the retransmission data or the newly transmitted data is transmitted based on the transmission order.

Specifically, determining the transmission sequence of the retransmitted data and the newly transmitted data based on the characteristics of the first configuration grant and the characteristics of the second configuration grant may include:

The configuration authorization configuration set comprises at least two groups of configuration authorization configurations, and the cycle size, transport Block (TB) size and modulation coding mode of each group of configuration authorization configurations are the same; different configuration grant configurations have different time domain position offsets, i.e. different time starting positions.

And if the first configuration authorization and the second configuration authorization belong to the same configuration authorization set and the characteristics of the first configuration authorization and the characteristics of the second configuration authorization are the same, transmitting the retransmission data preferentially.

Specifically, when the data transmission is performed on the retransmission data in a configuration authorization manner, the selected configuration authorization conforms to the following conditions:

configuring the authorized Physical Uplink Shared Channel (PUSCH) duration (maxUSCHduration) to be greater than or equal to the maximum value of the configured PUSCH duration; and the configured PUSCH duration is the PUSCH duration configured by the logic channel corresponding to the retransmission data.

The following further describes a data transmission process when the first configuration grant and the second configuration grant belong to the same configuration grant configuration set, with reference to specific embodiments.

In one embodiment, the data transmission method of the present application may include the following steps:

1) The network equipment sends configuration information to the terminal;

2) The terminal performs data transmission by using a configuration authorization mode according to the configuration information;

3) The terminal uses the configuration authorization to perform data transmission; due to the reason of a channel, the priority is reduced, or the LBT fails, and the like, newly transmitted data cannot be transmitted;

4) The terminal executes retransmission, and when the authorization of newly transmitted data conflicts with the authorization of retransmitted data, the terminal determines the characteristics of configuration authorization corresponding to the retransmitted data and the newly transmitted data respectively;

5) If the characteristics of the configuration authorization respectively corresponding to the retransmitted data and the newly transmitted data are the same, and the first configuration authorization and the second configuration authorization belong to the same configuration authorization set, the terminal preferentially transmits the retransmitted data.

The above embodiments will be described below with reference to examples.

In one example, the terminal is a UE, as shown in fig. 5, HP #1 cannot transmit at time T1 due to channel reasons, or due to a reduced priority, or due to LBT failure, and cannot complete retransmission in CG cycle 1 because retransmission requires time to process, so the UE needs to select an appropriate CG grant for retransmission in CG cycle 2.

Meanwhile, the UE generates a new data packet in the CG authorization period 2, and at this time, since the priorities of the logical channels multiplexed into all the configuration authorizations are the same, in order to avoid the increase of the HP #1 delay, the UE preferentially transmits the retransmission of the HP #1, and selects a configuration authorization on the subsequent resources, and performs the transmission of the newly generated data in the period 2.

The above embodiments and examples illustrate the data transmission process when the first configuration authorization and the second configuration authorization belong to the same configuration authorization configuration set, and the data transmission process when the first configuration authorization and the second configuration authorization belong to different configuration authorization configuration sets will be further described below with reference to the embodiments and examples.

The embodiment of the present disclosure provides a possible implementation manner, where determining a transmission sequence of retransmitted data and newly transmitted data based on a feature of a first configuration authorization and a feature of a second configuration authorization, the method may further include:

Specifically, determining the transmission order based on a first priority corresponding to the retransmitted data and a second priority corresponding to the newly transmitted data may include:

(1) If the first highest priority is higher than the second highest priority, the transmission sequence is to transmit the retransmission data preferentially;

(2) If the second highest priority is higher than the first highest priority, the transmission sequence is to transmit the newly transmitted data preferentially.

1) The network equipment sends configuration information to the terminal;

2) The terminal performs data new transmission by using a configuration authorization mode according to the configuration information;

5) If the characteristics of the configuration authorization respectively corresponding to the retransmitted data and the newly transmitted data are different, and the first configuration authorization and the second configuration authorization belong to different configuration authorization configuration sets, the terminal determines a transmission sequence based on a first priority corresponding to the retransmitted data and a second priority corresponding to the newly transmitted data.

The above embodiments will be described below with reference to examples.

In an example, as shown in fig. 6, the terminal is a UE, the network device configures logical channels with different priorities for configuration grant #1 and configuration grant #2, which are simply described as High prio and low prio priority orders, and at time T1, a new transmission of process # N is not successfully transmitted. Then at time T2 the UE may perform a retransmission on the configuration grant #2 while the UE has a new transmission at time T2 of the configuration grant # 2. At this time, since different logical channel priorities may be configured on different configuration grants, the UE compares the highest level of the logical channel multiplexed to the CG #2T2 time point corresponding to the newly transmitted data with the highest level of the logical channel corresponding to the data transmitted on the HP # N.

In this example, HP # N multiplexes data with a lower priority, and newly transmitted data multiplexed at CG #2T2 includes data with a higher priority, so that the priority of the logical channel corresponding to the newly transmitted data is higher than that of the logical channel corresponding to the retransmitted data, so that at T2, the UE preferentially transmits the newly transmitted data, and the retransmitted data HP # N continues to wait until the next available configuration grant.

The above embodiments illustrate the process of transmitting the retransmission data or the newly transmitted data by the terminal according to the feature of the configuration authorization.

In another embodiment, a Hybrid automatic repeat request (HARQ) process set may be configured first, and the retransmission data and the new transmission data may be transmitted by combining the HARQ process set.

The embodiment of the present disclosure provides a possible implementation manner, further including:

(1) Receiving a hybrid automatic repeat request (HARQ) process set configured by a network side, wherein the HARQ process set is configured for CG configuration with the same characteristics;

(2) If the new transmitted data authorization conflicts with the retransmitted data authorization, determining the transmission sequence of the retransmitted data and the new transmitted data based on a process set corresponding to the HARQ process of the new transmitted data and a process set corresponding to the HARQ process of the retransmitted data;

(3) The retransmission data or the newly transmitted data is transmitted based on the transmission order.

Specifically, determining the transmission sequence of the retransmitted data and the newly transmitted data based on the process set corresponding to the HARQ process of the newly transmitted data and the process set corresponding to the HARQ process of the retransmitted data may include:

a. if the HARQ process of the newly transmitted data and the HARQ process of the retransmitted data are in the same HARQ process set, the transmission sequence is to transmit the retransmitted data preferentially;

b. if the HARQ process of the newly transmitted data and the HARQ process of the retransmitted data are in different HARQ process sets, determining a transmission sequence based on a first priority corresponding to the retransmitted data and a second priority corresponding to the newly transmitted data;

Specifically, if the first priority is higher than the second priority, the transmission sequence is to transmit the retransmission data preferentially; if the second priority is higher than the first priority, the transmission sequence is to transmit the newly transmitted data preferentially.

The following describes a process for data transmission based on a HARQ process set in conjunction with specific embodiments.

1) The network equipment configures a hybrid automatic repeat request (HARQ) process set; the HARQ process set is configured for CG configuration of the same features;

2) The network equipment sends the HARQ process set to the terminal;
