Abstract

Various solutions for reducing uplink overhead with respect to user equipment and network apparatus in mobile communications are described. An apparatus may monitor a downlink channel. The apparatus may determining whether downlink control information (DCI) is received on the downlink channel. The apparatus may skip a hybrid automatic repeat request-acknowledgement (HARQ-ACK) feedback transmissionon an uplink channel in an event that no DCI is received on the downlink channel.

Description

[0001] cross reference [0002] This application is part of a non-provisional application claiming priority to U.S. Patent Application No. 62 / 616,599, filed January 12, 2018, the entirety of which is incorporated herein by reference. technical field [0003] The present invention relates generally to mobile communications, and in particular to reducing uplink overhead with respect to user equipment and network devices in mobile communications. Background technique [0004] Unless otherwise indicated herein, the approaches described in this section are not prior art to the claims listed below and are not prior art by virtue of being in this section. [0005] In New Radio (New Radio, NR), type 1 hybrid automatic repeat request-acknowledgment (automatic repeat request-acknowledgement, HARQ-ACK) codebook transmission is introduced to improve transmission reliability. When the user equipment (UE) is configured with "physical downlink shared channel (pdsch)-HARQ-ACK-Codebook = se...
