Abstract

The invention discloses a method for uplink transmission of URLLC service based on SUL. and URLLC UE, the service data correspondingly includes eMBB service data and URLLC service data, and it is characterized in that, when the eMBB UE transmits the eMBB service, the gNB allocates the time-frequency required for the eMBB service transmission to the UE in advance on the high-frequency uplink carrier Domain resources, when the eMBB UE has not yet sent the eMBB service on the resources allocated by the gNB, the URLLC UE requests to send the URLLC service. At this time, the gNB does not preempt the resources previously allocated to the eMBB UE, and the gNB chooses to allocate the time-frequency to the URLLC UE on the SUL carrier. domain resources, the subsequent URLLC UE sends URLLC services on the assigned SUL carrier. The SUL-based URLLC service uplink transmission method provided by the present invention has the advantages of reducing the influence on eMBB service transmission and the radio resource overhead of resource conflict resolution.

Description

technical field [0001] The present invention relates to the technical field of 5G communication, in particular to a SUL-based URLLC service uplink transmission method thereof. Background technique [0002] The fifth generation mobile communication (5G, Fifth Generation) standard contains new functional features, including: enhanced mobile broadband (eMBB) to address human-centric use cases for accessing multimedia content, services and data; Ultra-Reliable Low Latency Communication (URLLC) with specifications for latency and reliability; and massive Machine Type Communication (mMTC), which can allow a very large number of connected devices, Transfer relatively small amounts of non-latency sensitive information. [0003] In the actual communication process, URLLC services and eMBB services coexist. In view of the low-latency and high-reliability characteristics of URLLC services, URLLC will seize resources of eMBB services to complete service data transmission. Specifically...
