TECHNICAL FIELD

The present disclosure relates to methods for transmitting and receiving uplink control information for a next-generation/5G radio access network (hereinafter, referred to as “new radio” (NR) that is under discussion in the 3rd generation partnership project (3GPP).

BACKGROUND ART

Recently, the 3GPP has approved the “Study on New Radio Access Technology”, which is a study item for research on next-generation/5G radio access technology. On the basis of the Study on New Radio Access Technology, Radio Access Network Working Group 1 (RAN WG1) has been discussing frame structures, channel coding and modulation, waveforms, multiple access methods, and the like for the new radio (NR). In the NR, It is required to design not only to improve a data transmission rate as compared with the long term evolution (LTE)/LTE-Advanced, but also to meet various requirements in detailed and specific usage scenarios.

An enhanced mobile broadband (eMBB), massive machine-type communication (mMTC), and ultra-reliable and low latency communication (URLLC) are proposed as representative usage scenarios of the NR. In order to meet the requirements of the individual scenarios, it is required to design the NR to have flexible frame structures, compared with the LTE/LTE-Advanced.

Thus, a specific procedure is required for the flexible channel structure and uplink/downlink transmission for satisfying requirements of various usage scenarios using limited radio resources. In particular, in order for a user equipment to transmit uplink control information to a base station, methods are needed for satisfying requirements of each scenario by configuring various channel structures.

DETAILED DESCRIPTION OF THE INVENTION

Technical Problem

In accordance with embodiment of the present disclosure to address such issues, methods are provided i) for configuring a flexible uplink control channel for satisfying requirements of various usage scenarios, and ii) for enabling a user equipment to transmit uplink control information using the uplink control channel, for satisfying requirements of each usage scenario.

Technical Solution

In accordance with an aspect of the present disclosure, a method of a user equipment is provided for transmitting uplink control information. The method includes: receiving at least one of uplink control channel resource set configuration information and uplink control channel transmission information from a base station, configuring an uplink control channel including the uplink control information based on at least one of the uplink control channel resource set configuration information and the uplink control channel transmission information, and transmitting the uplink control channel to the base station. The uplink control channel is configured with one or more uplink control channel formats classified based on the number of symbols that configure the uplink control channel.

In accordance with another aspect of the present disclosure, a method of a base station is provided for receiving uplink control information. The method includes: configuring at least one of uplink control channel resource set configuration information and uplink control channel transmission information for a user equipment, transmitting at least one of the uplink control channel resource set configuration information and the uplink control channel transmission information, and receiving an uplink control channel configured to include the uplink control information based on at least one of the uplink control channel resource set configuration information and the uplink control channel transmission information. The uplink control channel is configured with one or more uplink control channel formats classified based on the number of symbols that configure the uplink control channel.

In accordance with still another aspect of the present disclosure, a user equipment is provided for transmitting uplink control information. The user equipment includes: a receiver receiving at least one of uplink control channel resource set configuration information and uplink control channel transmission information from a base station, a controller configuring an uplink control channel including the uplink control information based on at least one of the uplink control channel resource set configuration information and the uplink control channel transmission information, and a transmitter transmitting the uplink control channel to the base station. The uplink control channel is configured with one or more uplink control channel formats classified based on the number of symbols that configure the uplink control channel.

In accordance with yet another aspect of the present disclosure, a base station is provided for receiving uplink control information. The base station includes: a controller configuring at least one of uplink control channel resource set configuration information and uplink control channel transmission information for a user equipment, a transmitter transmitting at least configured one of the uplink control channel resource set configuration information and the uplink control channel transmission information, and a receiver receiving an uplink control channel configured to include the uplink control information based on at least one of the uplink control channel resource set configuration information and the uplink control channel transmission information. The uplink control channel is configured with one or more uplink control channel formats classified based on the number of symbols that configure the uplink control channel.

Effects of the Invention

In accordance with embodiments of the present disclosure, in networks deployed with one or more service scenarios, it is possible to satisfy requirements of each service and to enable a user equipment to transmit uplink control information by efficiently using radio resources.
