    摘要: Certain aspects of the present disclosure relate to techniques for indicating downlink assignments to a user equipment (UE). According to certain aspects, the techniques generally involve generating a downlink assignment index (DAI) indicating a number of assigned downlink transmissions for a user equipment (UE) configured to communicate using multiple component carriers and transmitting a physical downlink control channel (PDCCH) containing the DAI to the user equipment (UE) in a frequency division duplexing (FDD) subframe in which uplink and downlink transmissions may take place at the same time on different carrier frequencies.

    摘要: 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.

    摘要: Aspects disclosed herein relate to channel and interference estimations in a multiple transmission point environment including an eNB and RRHs. In the disclosed aspects, one or more transmission points can signal to a UE to measure channel state conditions based on a first and a second resource pattern. The UE may receive the signaling and perform interference estimation based at least in part on the first resource pattern, and channel estimation based at least in part on the second resource pattern. The UE may generate a channel state report based on the interference and channel estimations, and transmit the channel state report to a transmission point. The eNB may employ the received channel state report in scheduling one or more resources for use by the UE, and may select or adjust network traffic on the first and the second resource pattern, to affect the resulting channel and interference estimation.

    摘要: Techniques for conveying system bandwidths in a wireless communication system are described. In an aspect, system bandwidth information may be signaled to first user equipments (UEs) supporting a first set of system bandwidths and second UEs supporting a second set of system bandwidths. In one design, a base station may obtain and broadcast system bandwidth information indicating a first system bandwidth for the first UEs and a second system bandwidth for the second UEs. The first system bandwidth may be selected from the first set, and the second system bandwidth may be selected from the second set, which may be a superset of the first set. The system bandwidth information may include a first part and a second part. The first part may convey the first system bandwidth for the first UEs. The first and second parts may convey the second system bandwidth for the second UEs.

    摘要: A method, an apparatus, and a computer program product for wireless communication are provided for separating control transmissions and data transmissions within the coverage area of a plurality of transmission/reception points or points that are geographically displaced, the plurality of points comprising a macro node and a plurality of remote radio heads (RRHs) coupled to the macro node. Separating control transmissions and data transmissions in the macro node/RRH configuration may allow UEs to be associated with one set of transmission points for data transmissions and the same set or a different set of transmission points for common control signaling. Separating control transmissions and data transmissions may also allow for faster reconfiguration of antenna ports used for UE data transmission compared with reconfiguration via a handover process.
