Abstract

Various schemes for reducing uplink overhead with respect to user equipment and network devices in mobile communications. The device can monitor the downlink channel. The device may determine whether downlink control information (DCI) is received on the downlink channel. In the event that DCI is not received on the downlink channel, the device may skip sending hybrid automatic repeat request-acknowledgment (HARQ-ACK) feedback on the uplink channel.

Description

[0001] cross reference

[0002] The present application is a part of the non-provisional application of prioritization of U.S. Patent Application No. 62 / 616, 599, filed on January 12, 2018, which is incorporated herein by reference. Technical field

[0003] The present invention generally relates to mobile communications, and in particular, to reduce uplink overhead of user equipment and network devices in mobile communication. Background technique

[0004] Unless otherwise stated herein, the method described in this section is not the claimed claims, and is not as prior art due to the present sections.

[0005] In New Radio, NR, the type 1 mixing automatic retransmission request - confirmation (AutomaticRepeat Request-Acknowledge "is introduced to improve transmission reliability. When the user equipment (UE) is configured with a "Physical Downlink Shared Channel, PDSCH -HARQ-ACK-CODEBOOK = Semi-static", the UE needs to report in the HARQ-ACK codebook. The corresponding PDSCH rec...
