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

The embodiment of the present invention provides an uplink data transmission method, device, apparatus, and system, and relates to the field of communication, wherein the method includesthat a first terminal sends uplink data of a first service type on a first uplink resource; the first terminal receives a scheduling indication sent by an access network access device, wherein the scheduling indication includes a starting location and a scheduling period of the semi-persistent scheduling; the first terminal stopping sending the uplink data of the first service type before the starting location;the first terminal, after the location, sends the uplink data of the first service type again according to the scheduling period. The first terminal determines the scheduling start location and the scheduling period according to the scheduling indication, and the first terminal performs the operations of suspending sending and resending according to the starting location, so that the uplink transmission of the first service type can avoid the uplink transmission of a second service type so as to ensure the transmission delay requirement 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 ...
