    摘要: Methods, apparatuses, and computer program products are disclosed for facilitating indicating and detecting control region sizes. A multi-carrier communication between a wireless terminal and a base station is facilitated by a first carrier having a first control region size and a second carrier having a second control region size. Embodiments are disclosed in which control region sizes are ascertained from a control signal, wherein the control is generated by either scrambling an aspect of the control signal based on the second control region size, or relating the second control region size with the first control region size. Other disclosed embodiments for ascertaining control region sizes include a reverse interleaver embodiment, wherein a set of modulation symbols is mapped beginning from a last data symbol and ending with a first available data symbol.

    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.

    摘要: In accordance with one or more aspects and corresponding disclosure thereof, various aspects are described in connection with channel quality indicator (CQI) feedback in connection with one or more downlink carriers. An anchor carrier scheme is employed to provide channel quality indicator (CQI) feedback of one or more downlink carriers. An indication is set to identify that a designated uplink carrier is used to convey the CQI feedback. An uplink carrier is selected from a set of uplink carriers as an anchor carrier to convey the CQI feedback. CQI feedback is transmitted for one or more downlink carriers using the designated carrier.

    摘要: Methods, systems, apparatus and computer program products are provided to facilitate the configuration and allocation of control information associated with transmissions of a wireless communication system. In systems that utilize multiple component carriers, cross-carrier signaling may be used to carry the control information associated with one component carrier on a different component carrier. By allowing control information messages to share their allocated search spaces, the number of decoding attempts needed to obtain control information can be kept within desirable limits while improving scheduling and resource allocation flexibility. This Abstract is provided for the sole purpose of complying with the Abstract requirement rules that allow a reader to quickly ascertain the disclosed subject matter. Therefore, it is to be understood that it should not be used to interpret or limit the scope or the meaning of the claims.
