Embodiment Construction

[0034] An embodiment of the present disclosure relates to a method for confirming downlink data received on a downlink channel of an unlicensed spectrum in a wireless access network from a user equipment (UE) to a base station (BS) on an uplink channel, and a user using the method equipment. For example, in some embodiments, the mobile telecommunication system may be a 5G mobile network and the radio access network may be an unlicensed spectrum compliant with 5G NR-U (New Radio in Unlicensed Spectrum) defined by 3GPP standards.

[0035] The method includes the UE receiving a first downlink control information element that does not contain an explicit indication about the group identifier and / or does not include an explicit indication about the new feedback indicator. In some embodiments, the first downlink control information element may be a Fallback Downlink Control Information (FB-DCI) element.

[0036] Upon receiving the first downlink control information element, the UE ...

Abstract

Upon receiving a first DCI that does not contain an explicit indication regarding a group identifier and / or a new feedback indicator, the UE determines whether group-based acknowledgement feedback is activated. If so, the first DCI is allocated to the default group. The UE determines whether to switch a new feedback indicator value for the default group based on a comparison of the field value in the first DCI and the field value in the default group. The UE then sends acknowledgement feedback of the first group of downlink data to the base station in the uplink channel according to the new feedback indicator.

Description

technical field [0001] The present disclosure relates to the field of telecommunications, and in particular to a method for confirming downlink data received on an uplink channel to a downlink channel on an unlicensed spectrum in a radio access network from a user equipment to a base station, and a user equipment using the method. Background technique [0002] The radio access network is a part of the telecommunication system. The 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) defines the fifth generation (fifth generation, 5G) mobile communication network, which uses the new radio (5G New Radio, 5G NR) as the radio access technology (Radio Access Technology) , RAT). [0003] In the 5G NR RAT defined by the 3GPP standard, downlink transmission and uplink transmission are scheduled by the base station. Here, the downlink refers to the data sent from the base station (Base Station, BS) to the user equipment (User Equipment, UE), and the uplink ...
