    摘要: Certain aspects of the present disclosure relate to techniques for user-specific search space design for multi-carrier operation in Long Term Evolution Advanced (LTE-A) systems. The user-specific search space can be designed for searching Physical Downlink Control Channels (PDCCHs) transmitted on one component carrier (CC) that schedules Physical Downlink Shared Channel/Physical Uplink Shared Channel (PDSCH/PUSCH) transmissions on two or more different CCs. In one aspect, multiple independent user-specific search spaces can be designed. In another aspect, one user-specific search space can be randomly derived and then expanded to accommodate search for multiple CCs. In yet another aspect, the search space design can retain randomness in starting search element indices of multiple PDSCH/PUSCH CCs, while overlapping of search spaces for multiple PDSCH/PUSCH CCs can be avoided.

    摘要: The described aspects include methods and apparatus for aggregating carriers over a backhaul link between a relay and an evolved Node B (eNB). A first set of subframes of at least a first carrier of a plurality of carriers configured for communicating with an eNB over a backhaul link can be determined. A second set of subframes of at least a second carrier of the plurality of carriers configured for backhaul link communications is also determined, wherein the second set of subframes are different from the first set of subframes. Data received over a plurality of access link carriers can then be communicated to the eNB over the first carrier and the second carrier based at least on the first set of subframes and the second set of subframes.

    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.
