Description

Transmission method and terminal equipment

Technical Field

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

Background

Currently, a Long Term Evolution (LTE) system can support sidelink (or translated to sidelink, abbreviated as SL) transmission, that is, support terminal devices such as User Equipment (UE) to directly perform data transmission on a physical layer. The ProSe (Proximity-based services) may provide functions such as Direct discovery (for example, a UE discovers that there is a UE around which the UE may be directly connected) and Direct communication (for example, data interaction between the UE and the UE around) and the like.

In the ProSe Network architecture, a communication interface between the UE and the UE is referred to as a PC5 interface, and an interface between the UE and an Evolved UMTS Terrestrial Radio Access Network (E-UTRAN) device is referred to as a Uu interface. In R12, transmission priorities for data transmission and reception of the Uu port, transmission and reception of the PC5 port discovery, and transmission and reception of the PC5 port Communication are specified as follows (arranged from high to low): 1) transmitting and receiving data of a Uu port; 2) SL PC5 port data sending and receiving; 3) SL PC5Discovery signaling and listening.

In R13, in order to improve discovery transmission performance, a sidelink discovery gap (SL discovery gap) is introduced, and the sidelink discovery gap is specifically used for transmission and reception of discovery. In addition, in consideration of the specificity of the Uu port Random Access Channel (RACH), the transmission priorities for data transmission and reception of the Uu port, transmission and reception of the PC5 port discovery, and transmission and reception of the PC5 port Communication are reordered (ranked from high to low): 1) data transmission and reception of the Uu port RACH; 2) a SL PC5 port discovery channel notification message (within the SL discovery gap period); 3) transmitting the NON-RACH data through a Uu port; 4) SL PC5 port discovery listening (in SL discovery gap period); 5) receiving the NON-RACH data through a Uu port; 6) SL PC5 data transmission and reception.

In addition, in R13, a near field communication data Packet Priority (ProSe Per-Packet Priority, PPPP) is introduced, and the PPPP can be divided into 8 groups at most and takes values of 0-7. The smaller the PPPP value is, the higher the priority of data packet transmission is, one data packet may correspond to 1 or more PPPP values, and the PPPP value corresponding to the data packet may be referred to when the transmission priority of the data packet needs to be determined.

In a future fifth Generation New Radio (5G NR) system, in order to meet service requirements, a New service, i.e., an Ultra-Reliable and Low Latency communication (URLLC) service, is introduced, and transmission can be achieved over an NR Uu port. However, after introducing URLLC traffic, it is not clear how to transmit collided URLLC traffic and sidelink transmission traffic.

The transmission method of the present invention will be described below with reference to the embodiments and the drawings.

Referring to fig. 1, an embodiment of the present invention provides a transmission method, which is applied to a terminal device, and includes the following steps:

step 101: and when the URLLC service collides with the sidelink transmission service, performing transmission processing according to the transmission priority of the URLLC service and the sidelink transmission service.

It should be noted that the URLLC service may be selected as a Uu port service, and transmission may be implemented on a Uu port (for example, an NRUu port); the sidelink transmission service can be selected as a PC5 port service, and can realize transmission on a PC5 port.

Optionally, the sidelink transmission service may include at least one of:

sidelink Discovery (Sidelink Discovery) transport traffic and Sidelink Communication (Sidelink Communication) transport traffic.

According to the transmission method provided by the embodiment of the invention, when the URLLC service collides with the sidelink transmission service, the transmission processing is carried out according to the transmission priority of the URLLC service and the sidelink transmission service, so that the transmission of the collided URLLC service and the sidelink transmission service can be determined, the collision of corresponding transmission resources is avoided, and the requirement of the high-priority service can be further ensured to be preferentially met.

In the embodiment of the invention, when the terminal equipment selects the priority of the service transmission on the Uu port and the PC5 port, the influence of the specificity of the URLLC service can be increased and considered. Optionally, before step 101, the method may further include:

the terminal equipment judges whether the transmission service communicated with the network equipment is URLLC service;

and step 101 may comprise:

and when the transmission service communicated with the network equipment is the URLLC service and the URLLC service collides with the sidelink transmission service, the terminal equipment performs transmission processing according to the transmission priority of the URLLC service and the sidelink transmission service.

Therefore, the influence of the specificity of the URLLC service on the Uu port can be fully considered, and the requirement of the high-priority service is guaranteed to be met preferentially.

In the embodiment of the present invention, after introducing the URLLC service, a new Radio Network Temporary Identity (RNTI) may be introduced to the terminal device, where the new RNTI may be denoted as MCS-C-RNTI, and the MCS-C-RNTI may be used to indicate a new Modulation and Coding Scheme (MCS) TABLE (MCS TABLE), and the new MCS TABLE is generally used for the URLLC service, but is not limited to the URLLC service.

Optionally, the process of the terminal device determining whether the transmission service communicated with the network device is the URLLC service may be:

and the terminal equipment judges whether the transmission service communicated with the network equipment is the URLLC service or not according to the MCS-C-RNTI and/or the MCS table.

Wherein, the MCS-C-RNTI can be used for indicating whether a transmission service communicated with the network equipment is URLLC service. The MCS-C-RNTI may be used to indicate whether a transmission traffic communicated with the network device is URLLC traffic. That is, according to the MCS-C-RNTI, and/or the MCS table, it can be directly indicated whether data transmission on the Uu port is URLLC traffic.

Further, the MCS-C-RNTI and/or MCS table may be indicated by any one of:

downlink Control Information (DCI) and common search space (CCS)

It can be understood that, in the specific implementation, besides directly indicating whether the data transmission on the Uu port is the URLLC service according to the MCS-C-RNTI and/or the MCS table, the DCI may first indicate the MCS-C-RNTI and/or the MCS table, and further identify whether the data transmission on the Uu port is the URLLC service according to the MCS-C-RNTI and/or the MCS table; or the CCS defines and indicates the MCS-C-RNTI and/or the MCS table, and then whether the data transmission on the Uu port is the URLLC service is identified according to the MCS-C-RNTI and/or the MCS table.

The DCI may adopt a new DCI format or an existing DCI format, and when the existing DCI format is adopted, the extension field of the existing DCI may be used to indicate the MCS-C-RNTI and/or the MCS table.

In the embodiment of the present invention, when determining the transmission priority of the URLLC service and the sidelink transmission service, the terminal device may simply determine based on the service type, or may determine based on a preset condition, which is respectively described as follows.

Optionally, when the determination is made based on the service type, the terminal device may directly determine that the transmission priority of the URLLC service is higher than the transmission priority of the sidelink transmission service. Further, the process of the terminal device performing transmission processing according to the transmission priority of the URLLC service and the sidelink transmission service may include:

and the terminal equipment determines that the transmission priority of the URLLC service is higher than that of the sidelink transmission service, transmits the URLLC service and discards the sidelink transmission service.

Thus, the implementation of URLLC service can be preferentially guaranteed.

It can be understood that, in a specific implementation, when it is determined that the transmission priority of the URLLC service is higher than the transmission priority of the sidelink transmission service, in addition to performing the above-mentioned transmission processing, that is, transmitting the URLLC service, and discarding the sidelink transmission service, it may also perform transmission processing in other manners, such as transmitting the URLLC service, and buffering the data packet in the sidelink transmission service to transmit at a subsequent time, so as to avoid information omission.

Optionally, when the determination is performed based on a preset condition, the preset condition may be that a value of the priority identifier corresponding to the data packet in the sidelink transmission service is greater than (or smaller than) a preset threshold value. The preset threshold may be configured or preconfigured by the network device, agreed in advance by a protocol, or obtained by negotiating between the network device and the terminal device.

For example, when the sidelink transmission service is a sidelink discovery transmission service, the preset threshold may be represented as thresssl-TxPriority 1; or when the sidelink transmission service is the sidelink communication transmission service, the preset threshold may be represented as thresssl-TxPriority 2; or in specific implementation, the sidelink discovery transmission service and the sidelink communication transmission service may share a preset threshold.

Further, the process of the terminal device performing transmission processing according to the transmission priority of the URLLC service and the sidelink transmission service may include:

acquiring a priority identifier corresponding to each data packet in the sidelink transmission service;

respectively judging whether the priority mark corresponding to each data packet meets a preset condition;

when the priority mark of a first data packet meets the preset condition, determining that the transmission priority of the URLLC service collided with the transmission of the first data packet is higher than the transmission priority of the first data packet, transmitting the URLLC service, and discarding the first data packet; and/or

And when the priority mark of the second data packet does not meet the preset condition, determining that the transmission priority of the URLLC service collided with the transmission of the second data packet is lower than the transmission priority of the second data packet, transmitting the second data packet, and discarding the URLLC service.

It should be noted that the first data packet may include one or more data packets, and the second data packet may include one or more data packets. The priority identifier corresponding to each data packet may be selected by an application layer, and may be carried in Sidelink Control Information (SCI).

In addition, in specific implementation, when it is determined that the transmission priority of the URLLC service collided with the transmission of the first data packet is higher than the transmission priority of the first data packet, in addition to performing the above-mentioned transmission processing, that is, transmitting the URLLC service, and discarding the first data packet, it may also perform transmission processing in other manners, for example, transmitting the URLLC service, and buffering the first data packet for transmission at a subsequent time, so as to avoid information omission. Or, when it is determined that the transmission priority of the URLLC service colliding with the transmission of the second data packet is lower than the transmission priority of the second data packet, in addition to performing the above-mentioned transmission processing, that is, transmitting the second data packet, and discarding the URLLC service, it may also perform other transmission processing, such as transmitting the second data packet, and buffering the data packet in the URLLC service, so as to transmit at a subsequent time, thereby avoiding information omission.

Therefore, the transmission priority of the URLLC service and the sidelink transmission service is determined by the aid of the priority identification corresponding to each data packet in the sidelink transmission service, and the transmission priority of the URLLC service and the sidelink transmission service can be determined according to different conditions, so that collision of transmission resources can be avoided, and the requirement of the high-priority service can be guaranteed to be met preferentially.

In this embodiment of the present invention, optionally, the priority identifier may include at least one of the following items:

quality of service Class Identifier (QoS Class Identifier, QCI); for example, in a specific implementation, the value of the QCI may be set to an integer, and a smaller value of the QCI indicates a higher transmission priority of the corresponding packet, or a larger value of the QCI indicates a higher transmission priority of the corresponding packet;

at least one of the quality of service files QoSprofile corresponding to the QCI, that is, at least one QoSprofile of the qosprofiles corresponding to the QCI;

QoS Flow identification (QoS Flow ID, QFI); for example, in a specific implementation, the value of QFI may be set to be an integer, and the smaller the value of QFI, the higher the transmission priority of the corresponding data packet is represented, or the larger the value of QFI, the higher the transmission priority of the corresponding data packet is represented;

PPPP; for example, in a specific implementation, the value of PPPP may be set to an integer, and the smaller the value of further PPPP, the higher the transmission priority of the corresponding data packet is represented, or the larger the value of PPPP, the higher the transmission priority of the corresponding data packet is represented.

In the embodiment of the invention, when the sidelink discovery transmission service is carried out by utilizing the sidelink discovery interval, the required sidelink discovery interval can be configured for the terminal equipment by means of terminal request reporting and network configuration before the sidelink discovery transmission service is carried out. Specifically, when the sidelink transmission service includes a sidelink discovery transmission service, before step 101, the method may further include:

Wherein the carrier frequency is usable by the network device to configure the terminal device with the sub-link discovery interval at the carrier frequency.

Further, the interval form may include at least one of:
