摘要： 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.

摘要： A wireless communication system facilitates multichannel periodic and aperiodic feedback (e.g., Channel Quality Indicator (CQI), Rank indicator (RI), Precoding Matrix Indicator (PMI)) from a population of user equipment while facilitating legacy single carrier communication. Paired downlink (DL)/uplink (UL) or many-to-one mapping communication can be established by common system information or dedicated signaling. In one aspect, a flag sent by system information or by dedicated signaling can indicate which means controls. Feedback can be configured for each carrier independently reported in a concatenated in frequency fashion, reported in a cycle in time fashion, or reported in a staggered in time and frequency fashion. Feedback can be reported jointly as one wide bandwidth. Feedback can be a single report perhaps reported on a data channel for more capacity or by cycled carrier/subband reporting.

摘要： Systems, methods, apparatuses, and computer program products are described for power headroom reporting. A mobile device may identify a transmit power associated with each of a number of independently power controlled channels on one or multiple carriers configured for use by the mobile device. The transmit power may relate to one channel that is an uplink control channel, and one or more additional channels that are uplink shared channels. The identified transmit power of one channel (e.g., the uplink control channel) may be a virtual transmit power, while other identified transmit powers may be measured transmit powers for actual transmissions. The identified transmit powers may be added up, and the power headroom available for the mobile device may be calculated using the accumulated transmit powers. The mobile device may transmit a power headroom report to a base station.

摘要： Systems and methodologies are described that facilitate system frame number (SFN) indication and identification during a random access procedure (e.g., associated with a handover). As described herein, a target cell can configure one or more Random Access Responses (RARs) designated for transmission to a terminal during the access phase of a handover to include the SFN of the target cell. Techniques are further described herein by which the target cell can include SFN information in a sub-header associated with a RAR, in the payload of a RAR, and/or in other appropriate manners. In addition, the target cell can configure one or more flags of the RAR to indicate the presence of SFN information. Upon receiving a RAR with embedded SFN information, a terminal can utilize the SFN for operations such as frequency hopping or uplink resource configuration as described herein.

摘要： Systems and methodologies are described that facilitate selecting an uplink carrier for random access within a wireless environment having multiple carriers. Selection of an uplink carrier for random access can be randomly selected from a set of available uplink carriers. Additionally, the uplink carrier for random access can be selected based upon which uplink carrier is paired with an anchor carrier. Further, the uplink carrier for random access can be identified based upon a bandwidth related to the user equipment (UE). Reference signals can also be employed in order to identify an uplink carrier to perform random access.

摘要： A wireless communication system implementing Carrier Aggregation (CA) allows activation and deactivation of certain component carriers. Transmit power on an uplink component carrier being reactivated may be controlled by predetermining appropriate power control parameters to be used upon reactivation. The predetermined power control parameters may depend on a last known power control state of the deactivated component carrier or may be reset to apply an initial low power state.
