AI Technical Summary

Problems solved by technology

However, this move will result in a decrease in overall radio resource utilization, which may not be able to support large-scale connections of mMTC user devices
Moreover, the current uplink data signal transmission of URLLC and mMTC does not provide the transmission of uplink control signals. Therefore, the user equipment can only transmit uplink data signals according to the parameters pre-configured by the base station, which makes the transmission of uplink data signals inflexible.

Abstract

A user equipment (UE) and a base station (BS) are provided. The UE receives an uplink transmission configuration message indicating a pre-configured radio resource pool and an uplink control configuration message indicating an uplink control radio resource in the pre-configured radio resource pool from the BS. The UE transmits an uplink control message on the uplink control radio resource and transmits an uplink data signal on an uplink data radio resource in the pre-configured radio resource pool so that the BS receives the uplink data signal according to the uplink control message.

Description

technical field [0001] The invention relates to a user device and a base station. Specifically, the base station can allocate uplink control radio resources to a plurality of user equipments respectively from a pre-configured radio resource pool, and the user equipments can be allocated in the uplink grant-free condition The uplink control message is transmitted on the uplink control radio resource, and the uplink data radio resource is selected from the pre-configured radio resource pool to transmit the uplink data signal. Background technique [0002] With the rapid development of wireless communication technology, various applications of wireless communication have filled people's lives, and people's demand for wireless communication is also increasing. In order to meet various applications in life, the next-generation mobile communication system (currently commonly known as 5G mobile communication system) proposes new service types, such as: Ultra-reliable and Low Laten...
