Problems solved by technology

[0008] However, determining whether the user equipment performs contention-based random access or non-contention random access only according to whether the user equipment monopolizes the preamble resource will cause the base station to be unable to control the number of accessed user equipment, thus resulting in unbalanced load of the base station

Abstract

The invention provides an uplink signal sending method and user equipment. The sending method comprises the following steps: obtaining resource configuration information of an uplink signal; determining a random access mode to be used; and sending the uplink signal according to the obtained resource configuration information of the uplink signal and the determined random access mode, the random access mode comprising a four-step random access mode and a two-step random access mode.

Description

technical field [0001] The present disclosure relates to the technical field of wireless communication systems, and more specifically, the present disclosure relates to a method for sending an uplink signal and a user equipment using the method. Background technique [0002] In a wireless communication system, signal transmission mainly includes: signal transmission from base station (gNB) to user equipment (UserEquipment, UE) (called downlink transmission), and the corresponding time slot is called downlink time slot; from UE to base station The signal transmission (called uplink transmission), the corresponding time slot is called uplink time slot. [0003] In the downlink transmission of the wireless communication system, the wireless communication system periodically sends the synchronization signal and the broadcast channel to the user equipment through the synchronization signal block (Synchronization Signal / PBCH Block, SSB), wherein the period is the synchronization s...
