Embodiment Construction

[0023] The detailed description set forth below in connection with the accompanying figures is intended as a description of various configurations and is not intended to represent the only configurations in which the concepts described herein may be practiced. The detailed description includes specific details to provide a thorough understanding of various concepts. It will be apparent, however, to one skilled in the art that these concepts may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form in order to avoid obscuring the concepts.

[0024] For configured grants in carrier aggregation mode, different resource sets may be configured in different carriers. According to the present disclosure, it is disclosed for configured authorization defect feedback indicator (CG-DFI) feedback, configured authorization configuration and activation in case of carrier aggregation (CA) and / or authorization ass...

Abstract

Configured grant operations for new radio (NR) unlicensed spectrum (NR-U) carrier aggregation (CA) are disclosed. In an aspect, a method of wireless communication by a user equipment (UE) may include transmitting uplink (UL) data to a base station according to a configured grant configuration. The method may also include determining a carrier to receive feedback from the base station based on the configured grant configuration. The method may further include receiving feedback from the base station on the carrier in response to the transmitting of the UL data.

Description

[0001] This application claims Indian Provisional Application Serial No. 201941007087 filed on 22 February 2019 entitled "Configured Grant Operation for New Radio Unlicensed Spectrum Carrier Aggregation" and filed on 18 February 2020 entitled "CONFIGURED GRANT OPERATION FOR NEWRADIO UNLICENSED SPECTRUM CARRIER AGGREGATION," US Patent Application No. 16 / 793,756, the entire contents of which are expressly incorporated herein by reference. Background technique [0002] Aspects of the present disclosure relate generally to communication systems and, more particularly, to configured licensed operation for New Radio (NR) Unlicensed Spectrum (NR-U) Carrier Aggregation (CA). [0003] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging and broadcast. Typical wireless communication systems may employ multiple access techniques capable of supporting communication with multiple users by sharing availabl...
