Description

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a data transmission method, a terminal, and a network device.

Background

Both 4G and 5G are scheduling-based systems, and both downlink and uplink data transmissions are resource allocation based on base station scheduling. When the base station performs resource scheduling, according to QoS (quality of service) information acquired during service establishment, the base station maps QoS flows (quality of service flows) of the number of service data to DRBs (data service bearers) on the RAN (radio access network) side, and configures transmission parameters, including logical channel configuration, whether PDCP retransmission is performed, and the like, for each DRB based on the QoS characteristics of the QoS flows mapped thereon.

According to the prior art, the QoS guarantee level of one packet carrying all the packets is the same, i.e. after the first packet is lost, the subsequent packet may be continuously lost, so that the whole transmission link is not available.

Detailed Description

Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

In the following embodiments of the present invention, when a terminal acquires two or more uplink transmission resources overlapping in the time domain (i.e., uplink resource collision), the terminal can only transmit uplink data on one of the uplink resources, and therefore, the priority in the UE is introduced to ensure the transmission of the high priority service.

The intra-UE priority includes both MAC layer priority and physical layer priority.

The basic idea of MAC layer priority refers to that when a base station configures a priority (lch-BasedPrioritization) based on a logical channel for a terminal, the terminal compares the priorities of the logical channels of data mapped to two uplink resources when two uplink resources collide, and preferentially transmits the uplink resources including higher priority logical channel data.

Physical layer priority refers to, for pre-configured resources: the base station configures (ConfiguredGrantConfig) the physical layer priority phy-PriorityIndex of the pre-configured resource in the pre-configured resource CG for the terminal as p0 or p1, wherein p0 represents low priority, and p1 represents high priority; for dynamic scheduling resources, the base station configures priorities allowedPHY-PriorityIndex of corresponding uplink resources in a logic channel configuration (LogicalChannelConfig), and a dynamic scheduling command of the base station for scheduling the uplink resources comprises a priority indication p0 or p1 of the dynamic scheduling resources, and logic channel data only allows mapping to the uplink dynamic scheduling resources with the corresponding priorities. The base station carries the priority indication in the dynamic scheduling command, and if two uplink resources collide, only the uplink transmission is allowed to be sent on the uplink resource with high priority.

The logic channel priority, the transmission priority is configured for the determined service, and the QoS guarantee strength of each service data packet is the same as long as the parameters are not reconfigured for the data of one service, namely, the service data packets have the same performance parameter budget such as time delay, reliability and the like.

The industrial internet has introduced the concept of survivinal time (time-to-live timer), which is used to characterize the availability of services. In the industrial internet, the service requirement parameters of partial periodic deterministic communication service are shown in the following table, and besides the traditional parameters of transmission interval, message size, time delay and the like, survivinal time is introduced.

Meter 1:Periodic deterministic communication service performance requirements

Survival time is defined as in table 1, when the data transmission is incorrect, the survivin time is started, if the subsequent data can be correctly transmitted during the validity period of the survivin time, the service transmission is considered to be available (availability), and if the survivin time is overtime, the data cannot be correctly transmitted, the transmission between the original device and the target device is considered to be unavailable.

As shown in fig. 2, a data transmission method is applied to a terminal, and the method includes:

step 21, sending a priority transmission request to a network side;

Step 22, the receiving network side transmits the uplink data on the resources scheduled by the network side based on the response of the priority transmission request.

In this embodiment of the present invention, the priority transmission request is sent to the network side; the receiving network side transmits uplink data on the resources scheduled by the network side based on the response of the priority transmission request, so that the availability of a communication link is ensured when the 5G system is accessed to the industrial Internet, and the problem of effective transmission of service data is solved.

In an optional embodiment of the present invention, in step 21, the terminal sends the priority transmission request to the network side before a survival time timer (as shown in fig. 1) of the uplink target service expires, where the survival time timer is obtained by at least one of the following manners:

1) The terminal obtains the parameters of the survival time timer through an application layer;

2) And the terminal receives the notification message of the network side and obtains the parameters of the survival time timer through the notification message.

The embodiment of the invention introduces a data transmission method for coping with the survival time timer, and the transmission priority of the specific service is triggered and improved by a terminal request mode so as to reduce the probability of unavailable transmission links, thereby improving the feasibility of overall service data transmission in the industrial Internet.

In an optional embodiment of the present invention, when the terminal obtains the parameter information of the time-to-live timer through the application layer at the terminal side, the parameter of the time-to-live timer is the time length (i.e. expressed by time length) of the time-to-live timer for a specific service or QoS flow, or a multiple of the service data period (i.e. the unit is a number).

The embodiment of the invention is suitable for the service with longer life time timer, because if the life time timer is shorter, if the transmission priority of the service is increased immediately after the occurrence of data transmission errors, the transmission of other services can be influenced by overdriving reaction, and the resource waste can be caused.

In an optional embodiment of the present invention, the network side notifies the terminal of a survival time timer, where the network side obtains the survival time timer of the uplink QoS flow from a delay sensitive Communication auxiliary information TSCAI (TSC (TIME SENSITIVE Communication) ASSISTANCE INFORMATION) sent from the core network to the network side; the network side sends the survival time timer to the terminal and indicates whether the terminal allows the priority transmission request reporting mechanism to be started or not (the permission indication is optional).

In an optional embodiment of the present invention, in step 21, sending a priority transmission request to the network side may include:

And when the preset time period arrives after the survival time timer is started, sending a priority transmission request to the network side. The preset time period may be configured by the base station or set by the terminal itself.

In this embodiment of the present invention, before the terminal detects that the lifetime timer of the uplink transmission of the specific service expires, a priority transmission request is sent to the base station. After receiving the request for preferential transmission, the base station can schedule the uplink transmission of the service preferentially, thereby ensuring that the correct transmission of the service data is completed before the time-out of the life time timer, and further ensuring the availability of the communication link.

In an alternative embodiment of the present invention, the time-to-live timer is started when:

After the terminal transmits the uplink transmission of the data packet containing the QoS flow of the target service or the uplink transmission of the data packet containing the data service bearer DRB mapped by the QoS flow; or alternatively

In an alternative embodiment of the present invention, the physical layer signaling may be a scheduling request, where a scheduling request resource corresponding to the scheduling request is configured as a scheduling request resource corresponding to a logical channel that needs to be transmitted with priority, or the scheduling request uses a scheduling resource that is specifically configured to indicate that the request is transmitted with priority.

In an alternative embodiment of the present invention, the RRC signaling includes at least one of:

A priority transmission request indication;

Remaining time information of the time-to-live timer.

In an alternative embodiment of the present invention, the MAC CE signaling includes at least one of:

sequencing identification of RB/LCID configured by the terminal;

A priority transmission request indication;

Remaining time information of the time-to-live timer.

Here, the MAC CE specifically carries one or more uplink traffic indications that need to be preferentially transmitted, where the uplink traffic indication may be a DRB ID (DRB number) or an LCID (logical channel number) or a QoS Flow ID (QFI).

The following describes the specific implementation procedure of the above embodiment in conjunction with specific implementation examples:

Example 1: the terminal sends a priority transmission request through RRC signaling

The terminal acquires survivinal time corresponding to the uplink service; acquiring a survivin time starting condition, starting survivin time, and triggering a priority transmission request; transmitting a priority transmission request (RRC) signaling, wherein the content of the priority transmission request (RRC) signaling comprises: RB ID, LCID, and/or QoS flow ID; a priority transmission request indication; remaining survivinval time (optional). And receiving the response of the base station side.

The base station side optionally informs the terminal of the survivin time value and/or the starting condition of survivin time. The base station receives the RRC signaling of the priority transmission request sent by the terminal side. And responding to the priority transmission request sent by the terminal, and sending resource allocation/configuration and/or service configuration capable of improving the service reliability.

Example 2: the terminal sends a priority transmission request through MAC signaling:

And the terminal acquires the survivinal time corresponding to the uplink service. And acquiring a survivin time starting condition, starting survivin time, and triggering a priority transmission request. The priority transmission request is sent through the MAC signaling, and the priority transmission request MAC CE comprises the following contents: RB ID, LCID and/or QoS Flow ID (QFI), which may be values configured by RRC signaling in the MAC CE, or a ranking number (in value size or configuration order) of RBs/LCIDs configured by the UE; a priority transmission request indication; remaining survivinval time (optional). And receiving the response of the base station side.

The base station side optionally informs the terminal of the survivin time value and/or the starting condition of survivin time. The base station receives a priority transmission request (MAC CE) sent by the terminal side. And responding to the priority transmission request sent by the terminal, and sending resource allocation/configuration and/or service configuration capable of improving the service reliability.

Example 3: the terminal sends a priority transmission request through physical layer signaling:

and the terminal acquires the survivinal time corresponding to the uplink service. And acquiring a survivin time starting condition, starting survivin time, and triggering a priority transmission request. The method comprises the steps of sending a priority transmission request through physical layer signaling, wherein the physical layer signaling can be a scheduling request, and the scheduling request adopts scheduling request resources corresponding to a logic channel needing priority transmission, namely, the priority transmission request becomes a condition for triggering the scheduling request; or, the scheduling request uses a specially configured SR resource representing a priority transmission request, and the SR resource can be configured for different logic channels respectively; and receiving the response of the base station side.

The base station side optionally informs the terminal of the survivin time value and/or the starting condition of survivin time. The base station receives a priority transmission request physical layer signaling sent by a terminal side; and responding to the priority transmission request sent by the terminal, and sending resource allocation/configuration and/or service configuration capable of improving the service reliability.

According to the data transmission method disclosed by the embodiment of the invention, the transmission priority of the specific service is triggered and improved in a terminal request mode, so that the probability of unavailable transmission links is reduced, and the feasibility of overall service data transmission in the industrial Internet is improved. The invention is suitable for the service with longer survivin time length, because if survivin time is longer, if the transmission priority of the service is increased immediately after a data transmission error occurs, the over-excitation reaction can be caused, the transmission of other services can be influenced, and the resource waste can be caused.
