Embodiment Construction

[0087] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0088] Three major scenarios of 5G were defined at the 3GPP meeting: eMBB, mMTC and uRLLC. Among them, eMBB refers to high-traffic mobile broadband services such as 3D / ultra-high-definition video, mMTC refers to large-scale Internet of Things services, and uRLLC refers to low-latency, high-reliability connection services such as unmanned driving and industrial automation. When the terminal transmits any of the three services, the terminal first sends a resource application to the access network device, and the access network device allocates resource scheduling to the terminal, and the terminal then transmits data according to the resource scheduling.

[0089] When performing resource scheduling, there are two scheduling methods ...

Abstract

Embodiments of the present application provide an uplink data transmission method, device, device, and system, which relate to the communication field. The method includes: a first terminal sends uplink data of a first service type on a first uplink resource; The scheduling instruction sent by the network access device, the scheduling instruction includes the starting position and scheduling period of the semi-persistent scheduling; the first terminal suspends sending the uplink data of the first service type before the starting position; After the location, the uplink data of the first service type is sent again according to the scheduling period. In this application, the first terminal determines the scheduling start position and the scheduling cycle according to the scheduling instruction, and the first terminal performs the operation of suspending transmission and resending according to the starting position, so that the uplink transmission of the first service type can avoid the second service type Uplink transmission, thus ensuring the transmission delay requirements of the second service type.

Description

technical field [0001] The present disclosure relates to the communication field, and in particular to an uplink data transmission method, device, device and system. Background technique [0002] The Third Generation Partnership Project (Third Generation Partnership Project, 3GPP) meeting defined three major scenarios of 5G: enhanced mobile broadband (enhance Mobile Broad Band, eMBB), massive machine type communication (massive Machine Type of Communication, mMTC) and Ultra Reliable & Low Latency Communication (uRLLC). [0003] Since terminals supporting uRLLC services have high requirements on transmission delay, and uRLLC can initiate its own service transmission at any time according to its own needs, if the current physical transmission resources carry eMBB services, the transmission between the two will occur conflict. On the one hand, the reliability of the uRLLC service is affected, and on the other hand, the transmission of the eMBB is also affected. Contents of ...
