    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: Systems and methodologies are described that facilitate scrambling of downlink reference signals utilizing a pseudo-random sequence (PRS) corresponding to a primary synchronization code (PSC) and secondary synchronization code (SSC) combination. Utilization of the combination allows for orthogonal sequencing to be removed from the scrambling. This can be beneficial, for example, where resources required for orthogonalizing the reference signal outweigh the benefit of utilizing the orthogonal sequences. In such scenarios, selective scrambling can be utilized such that the orthogonal sequence or instead the PSC/SSC combination can be provided to leverage advantages of both mechanisms in the given scenarios.

    摘要: Techniques for supporting operation of relay stations in wireless communication systems are described. In an aspect, a bitmap may be sent by a base station and/or a relay station to identify subframes of at least two types in multiple radio frames. For example, the bitmap may indicate whether each subframe covered by the bitmap is of a first type or a second type. UEs may use the bitmap to control their operation. For example, a UE may perform channel estimation or measurement for the subframes of the first type and may skip channel estimation and measurement for the subframes of the second type. In another aspect, a base station may transmit data and/or control information on resources not used by a relay station to transmit a reference signal. This may avoid interference to the reference signal from the relay station, which may improve performance for UEs communicating with the relay station.

    摘要: Techniques for reporting channel state information (CSI) are disclosed. A user equipment (UE) may be configured for operation on multiple carriers with different configurations, e.g., FDD and TDD carriers and/or carriers with different uplink-downlink configurations. The multiple carriers may have different subframes for making measurements for CSI and/or different subframes for sending CSI. In response to a CSI request, the UE may determine at least one reference subframe to use for determining CSI for the multiple carriers. The reference subframe may be common to the plurality of carriers and may, for example, be based the subframe in which the CSI request in sent. Alternatively, the reference subframe may be different for different carriers such as when it is based on different HARQ timelines applicable for the different carriers. The UE may determine the CSI for the multiple carriers based on the reference subframe(s) and may report the CSI.
