Downlink assignment indicator design for multi-carrier wireless communication

摘要

Systems and methodologies are described herein that facilitate various techniques for enhanced downlink assignment index (DAI) signaling in a multi-carrier wireless communication system. As described herein, DAI and/or other indicator signaling transmitted on a first carrier can be configured to carry information relating to a number of downlink transmission assignments applied to at least a second carrier, which in some cases can be disparate from the first carrier. To these ends, described herein are techniques for cross-carrier DAI signaling, multiple DAI signaling, aggregate DAI signaling, and other similar techniques. As additionally described herein, DAI signaling can be related to downlink control transmissions and/or downlink data transmissions in connection with respective techniques that can be applied to the DAI signaling.

1. A method, comprising:
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 in the plurality of carriers; and configuring, for communication over at least one or more second carriers in 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.
