DOWNLINK ASSIGNMENT INDICATOR DESIGN FOR MULTI-CARRIER WIRELESS COMMUNICATION Russian patent published in 2014 - IPC H04L27/26 

FIELD: radio engineering, communication.

SUBSTANCE: method involves identifying a plurality of carriers configured for communication in a wireless communication system; determining a number of downlink transmission assignments associated with one or more first carriers from the plurality of carriers; and configuring, for communication over at least one or more second carriers from the plurality of carriers, at least one indication that specifies the number of downlink transmission assignments associated with at least the one or more first carriers. At least one indication includes a downlink assignment index (DAI) signalling, wherein the DAI signalling includes a time-based DAI, and a DAI indicating the number of downlink transmission assignments on the plurality of carriers.

EFFECT: reduced cost of transmitting cyclic shift values, high efficiency of using a bundling window.
