    摘要: Techniques for acknowledging data transmissions in a multi-carrier wireless communication network are disclosed. In some aspects, a user equipment (UE) receives a data transmission on at least one component carrier (CC) in a plurality of configured CCs. The UE determines acknowledgement/negative acknowledgement (ACK/NACK) information for the data transmission and determines an uplink channel for sending the ACK/NACK information. When the ACK/NACK information is sent on a PUCCH, the UE may perform power control based on which CCs in the plurality of configured CCs data is received. When the ACK/NACK information is sent on a PUSCH, the UE may determine a number of resource elements based on its CC configuration.

    摘要: Techniques for reporting channel state information (CSI) in a multi-carrier wireless communication system are disclosed. In some examples, a user equipment determines a configuration for reporting CSI for each component carrier (CC) in a plurality of component carriers. For a first subframe, the user equipment determines a priority for transmitting CSI associated with the plurality of CCs based at least in part on the configuration. The user equipment sends, in the first subframe, a CSI report including the prioritized CSI. The CSI report can include CSI for a single CC, or CSI for multiple CCs. For multi-CC reporting of CSI, the user equipment can multiplex CSI reports or CSI elements for the plurality of CCs up to an available payload size.

    摘要: Techniques for transmitting data by a power-limited user equipment (UE) in a wireless communication system are described. The UE may transmit data of different types on one or more carriers and may be power limited. In some aspects, the UE may prioritize the data to transmit based on the priorities of the different data types, the priorities of carriers on which the data is transmitted, and/or other criteria. In one design, the UE may obtain data to transmit on at least one carrier for the uplink. The UE may determine that it is power limited for transmission on the at least one carrier. The UE may prioritize the data to transmit based on at least one criterion. The UE may allocate its available transmit power to the prioritized data and may transmit the prioritized data at the allocated transmit power.

    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 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: In accordance with one or more aspects and corresponding disclosure thereof, various aspects are described in connection with channel quality indicator (CQI) feedback in connection with one or more downlink carriers. An anchor carrier scheme is employed to provide channel quality indicator (CQI) feedback of one or more downlink carriers. An indication is set to identify that a designated uplink carrier is used to convey the CQI feedback. An uplink carrier is selected from a set of uplink carriers as an anchor carrier to convey the CQI feedback. CQI feedback is transmitted for one or more downlink carriers using the designated carrier.

    摘要: Techniques for supporting communication with carrier extension are described. In one design, a base carrier and at least one segment available to a user equipment (UE) for communication may be determined. At least one operating parameter for the UE may be determined based on a composite bandwidth of the base carrier and the at least one segment. The UE may communicate based on the at least one operating parameter, which may include a resource block group (RBG) size and/or a bitmap used for resource allocation on the downlink, a gap used for resource allocation with frequency hopping on the downlink, a number of hopping bits used for resource allocation with frequency hopping on the uplink, a subband size and/or a number of bandwidth parts used for channel quality indicator (CQI) reporting, a sounding reference signal (SRS) bandwidth and/or a SRS configuration for SRS transmission on the uplink, and/or other operating parameters.
