Abstract

The invention provides a random access processing method, a user terminal and a network side device. The method comprises the steps of selecting a backspacing value of a next random access try based on a backspacing range corresponding to the random access if the random access try is failed, wherein the backspacing range is a range value determined based on setting parameters corresponding to thecurrent random access try; and delaying the next random access try based on the backspacing value. As the backspacing range is determined based on the setting parameters corresponding to the current random access try, configuration of different backspacing ranges for different random access is realized, configuration flexibility of the backspacing range is improved and different delay performancesfor different random access configuration can be realized.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a random access processing method, user terminal and network side equipment. Background technique [0002] Compared with the past mobile communication system, the future 5G mobile communication system needs to adapt to more diverse scenarios and business requirements. The main scenarios of 5G include eMBB, URLLC, and mMTC. These scenarios place requirements on the system for high reliability, low latency, large bandwidth, and wide coverage. In order to meet different needs of services and different application scenarios, the subcarrier spacing of the 5G system is no longer a single 15kHz like in LTE. The system can support multiple subcarrier spacings, and different subcarrier spacings can be applied to different scenarios. For example, for a high frequency band and a large bandwidth, a relatively larger subcarrier spacing can be configured. At the same time, a large ...
