    Abstract: Systems and methodologies are described that facilitates communicating Physical Control Format Indicator Channel (PCFICH) information to a user equipment (UE) in which the PCFICH information is specific to a particular component carrier. The PCFICH information for each component carrier can be communicated via an anchor component carrier in order to reduce decoding each PCFICH information for each component carrier. In particular, the PCFICH information can be decoded for an anchor component carrier and PCFICH information for additional carriers can be included in a Multi-Carrier (MC) grant of the Physical Downlink Control Channel (PDCCH).

    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: Certain aspects of the present disclosure present techniques for generating a downlink control information (DCI) message which may be transmitted with a particular organization of a downlink control channel and techniques for receiving the same. The DCI message may support uplink enhancements such as single-user multiple input multiple output (SU-MIMO) and clustered DFT-S-OFDM, and may limit blind decoding operations at a user equipment.

    Abstract: Techniques for performing channel interleaving to achieve similar SINRs for multiple code blocks are described. In one design, a transmitter station (e.g., a base station or a UE) determines a plurality of resource groups assigned for data transmission. Each resource group includes a plurality of resource elements formed by a cluster of subcarriers in a time interval. The transmitter station partitions a transport block into a plurality of code blocks, processes each code block to obtain data symbols for that code block, and maps the data symbols for each code block to at least one resource element in each of the plurality of resource groups. The transmitter station transmits the mapped data symbols for the plurality of code blocks to a receiver station. In one design, the transmitter station receives an ACK or a NACK for the transport block and retransmits all code blocks if a NACK is received.

    Abstract: Systems and methods for a wireless communication system are provided. The method includes estimating a time-variation of a channel through which the wireless communication system transmits. This also includes decreasing the estimated time-variation of the channel from a signal transmitted by the wireless communications system. An iterative process and components are provided to allow efficient and accurate frequency domain equalization. Various processing components remove or mitigate components of channel variation and recovers a circular convolution, in order that frequency domain equalization (FDE) structures developed for static channels become effective in time-varying channels. For time varying channels, a vector is determined which represents a degradation of the corresponding equivalence between the time domain and the frequency domain which is relied upon by the frequency domain equalization. Thus, a time variation cancellation process is performed where said vector is iteratively subtracted from the frequency domain equalization. In this manner, frequency domain equalization performance is improved in the presence of time varying channels.
