Abstract

The invention discloses a service data transmission method, a base station and a terminal. The method comprises the following steps: determining numerical value configuration Numerology information oftarget service, the maximum transmission times of the service data of the target service and a redundancy version adopted in every transmission according to a transmission performance indicator of the target service; and within the maximum transmission times, sending the service data to the terminal through a transmission resource corresponding to the numerical value configuration information byadopting the redundancy version corresponding to every transmission. The base station disclosed by the invention determines the numerical value configuration information according to the transmissionperformance indicator of the generated service to ensure the delay requirements of the service transmission, and further determines the maximum transmission times and the redundancy version adopted in every transmission according to the transmission performance indicator of the generated service to ensure the transmission reliability of the service data. If the transmission performance indicatorsof the service are different, various parameters configured to the service are different so as to meet different reliability and delay requirements.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a service data transmission method, a base station and a terminal. Background technique [0002] At present, the general LTE service is based on the stop-and-wait method, that is, the terminal (UE, User Equipment) feeds back a response to the base station after receiving the downlink data service, and the base station determines whether to retransmit according to the response. When uplinking data, an acknowledgment is sent to the UE, and the UE determines whether to retransmit according to the acknowledgment. Compared with traditional mobile communication systems, future New Radio (NR, New Radio) mobile communication systems need to adapt to more diverse scenarios and business requirements. The main scenarios of NR include mobile broadband enhanced eMBB, large-scale Internet of Things mMTC, and ultra-high reliability and ultra-low latency communication URLLC. T...
