Title:
CODE BLOCK GROUP FEEDBACK TECHNIQUES FOR MULTIPLE CARRIERS OR TRANSMISSION TIME INTERVALS
Document Type and Number:
WIPO Patent Application WO/2019/014175
Kind Code:
A3
Abstract:
Methods, systems, and devices for wireless communication are described that provide for configuration of multiple component carriers (CCs) or multiple transmission time intervals (TTIs) for data transmission to a user equipment (UE). Feedback resources may be configured for transmission of feedback information from the UE, and one or more CCs or TTIs may be configured for either code block group (CBG) feedback or transport block (TB) feedback, and one or more other CCs or TTIs may be configured for TB feedback. A UE may select whether to use CBG feedback or TB feedback for one or more CCs or TTIs, based at least in part on an amount of feedback information to be transmitted, an amount of available feedback resources, an error pattern associated with one or more of the CCs or TTIs, or any combination thereof.
