Abstract

The invention discloses a random access transmission method and a terminal. The method comprises the steps of acquiring a demodulation reference signal DMRS sequence generation parameter of a physicaluplink shared channel PUSCH; and sending a random access message according to the DMRS sequence generation parameter, wherein the random access message corresponds to the PUSCH and the PRACH. In therandom access process of the terminal provided by the embodiment of the invention, the random access message is sent on the random access resource according to the DMRS sequence generation parameter of the PUSCH. Accordingly, network equipment demodulates the PUSCH on the random access resource according to the DMRS sequence generation parameter, thereby obtaining the corresponding random accessmessage, improving the success rate of data detection, avoiding unnecessary blind detection, and reducing the detection complexity of the network equipment.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a random access transmission method and a terminal. Background technique [0002] Fifth generation (5 th Generation, 5G) mobile communication system, or New Radio (NR) system, needs to adapt to diverse scenarios and business requirements. The main scenarios of NR system include enhanced Mobile Broadband (eMBB) communication, large-scale IoT (massive Machine Type Communications, mMTC) communication and ultra-reliable and ultra-low latency communication (Ultra-Reliable and Low Latency Communications, URLLC). These scenarios put forward requirements for the system such as high reliability, low latency, large bandwidth, and wide coverage. For services that occur periodically and have a fixed packet size, in order to reduce the overhead of downlink control signaling, network devices can use semi-static scheduling to continuously allocate certain resources for the tra...
