    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 physical uplink control channel (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 physical uplink shared channel (PUSCH), the UE may determine a number of resource elements based on its CC configuration.

    摘要: Techniques for sending control information relating to multiple downlink carriers and data on a single uplink carrier are described. A user equipment (UE) may be scheduled to transmit on a designated uplink carrier. The UE can multiplex control information for multiple downlink carriers with data for transmission on the uplink carrier in a same subframe. Multiplexing may be performed according to a type of the control information and/or an ordering, priority, or association of the downlink carriers. The UE can selectively encode the control information separately for each downlink carrier and/or jointly across downlink carriers. The control information may be mapped to a single layer or multiple layers of a data channel. The UE may send the multiplexed control information and data on the data channel in the subframe while maintaining a single-carrier waveform.

    摘要: Systems and methodologies are described that facilitate reducing false detections of control channels during blind decode when multiple component carriers are configured. A UE can perform blind detection of control channels on a plurality of carriers, wherein each control channel detected can be validated to reduce false detections. In one aspect, a reference carrier can be selected, wherein one or more detected control channels are validated so long as one detected control channel is on the reference carrier. In another aspect, control channel can be bundled such that multiple control channel detections are required for validation. Moreover, dummy control channels can be introduced that provide UE with guidance during blind decoding, as well as provide validation of detections. Further, various combinations of a reference carrier, bundling, and/or a dummy control channel can be utilized.
