    Abstract: Multiple downlink (DL) and uplink (UL) carriers can enhance wireless communication between nodes and user equipment (UE). Among the carriers, it is beneficial to have some special, by configuration designated carriers to provide synchronization, system information, paging, data and control for multi-carrier enabled UEs. Thereby, overhead system information can be reduced. For instance, synchronization and paging for a certain cell are not provided on all carriers. A carrier can provide backward compatibility for single carrier UEs for access, synchronization, broadcast, and new control region within the data region of the legacy terminals. Coordination between nodes for selecting anchor carriers that mitigate interference and for transmit power control for non-anchor carriers provide further network performance advantages.

    Abstract: Techniques for supporting fallback operation in a multi-carrier communication system are described. In one aspect, a UE may determine at least one first downlink control information (DCI) format to monitor on a first carrier. The UE may monitor for the first DCI format(s) on the first carrier to detect DCI sent to the UE. The UE may receive a reconfiguration message related to communication on a plurality of carriers by the UE with cross-carrier signaling, and may determine at least one second DCI format to monitor on the first carrier based on the reconfiguration message. The UE may monitor for the first DCI format(s) and the second DCI format(s) on the first carrier after receiving the reconfiguration message.

    Abstract: Systems and methodologies are described herein that facilitate various techniques for enhanced downlink assignment index (DAI) signaling in a multicarrier 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.
