摘要： The present disclosure describes methods and apparatuses for improved transport block decoding in devices capable of wireless communication, which may include user equipment and network entities. For example, the present disclosure presents methods and apparatuses for decoding a code block from a plurality of code blocks corresponding to a transport block, obtaining a reliability indicator that identifies a reliability of the decoding of the code block, comparing the reliability indicator to a reliability threshold, and determining whether to decode a subsequent code block from the plurality of code blocks based on the comparing. Furthermore, these methods and apparatuses may include determining not to decode at least one subsequent code block of the transport block where the comparing indicates that the reliability indicator is less than the reliability threshold. As such, device power is not unnecessarily consumed by decoding likely superfluous code blocks.

摘要： In an aspect of the disclosure, a method, a computer program product, and an apparatus are provided. The apparatus switches from a multiple receive diversity (RxD) on state to a RxD off state upon detecting a condition is in a certain state. The condition may be a high measure of correlation between a first antenna and a second antenna, or a high level of imbalance between the first antenna and the second antenna. The apparatus also periodically switches back to the RxD on state to determine if the condition remains in the certain state. The time period between entries into the RxD on state is dynamically adjusted as a function of prior conditions.
