Abstract

The present disclosure relates to packaging of feedback information bits in a wireless communication system. Some embodiments are applicable to both Frequency Division Duplexing (FDD) and Time Division Duplexing (TDD) systems, whereas other embodiments are particularly well-suited for TDD systems. In some embodiments, a method of operation of a wireless device in a cellular communications networkcomprises receiving, from the cellular communications network, an indication of one of a plurality of predefined sets of feedback information codebook sizes, the plurality of predefined sets of feedback information codebook sizes being disjoint subsets of a plurality of predefined feedback information codebook sizes. In some embodiments, the indication enables the wireless device to return an expected number of feedback information bits to the cellular communications network, particularly in a saturation where the wireless device misses one or more downlink assignments.

Description

[0001] related application [0002] This application claims the benefit of PCT Patent Application Serial No. PCT / CN2015 / 090840 filed September 25, 2015, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0003] The disclosed subject matter generally relates to telecommunications. Certain embodiments relate more specifically to uplink control channel transmissions (e.g., physical uplink control channel (PUCCH) transmissions in 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE)), further enhancing carrier aggregation (FeCA), and / or Downlink Assignment Index (DAI). Background technique [0004] Carrier aggregation (CA) [0005] The use of LTE carrier aggregation, introduced in 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) Release (Rel) 10 and enhanced in Rel-11, enables peak Improvements in data rate, system capacity, and user experience, the multiple carriers can reside in the same band or i...
