    摘要： Techniques for sending control information in a manner to improve reliability are described. In an aspect, control information may be sent on multiple control channels, which may be independently configured and operated, in order to improve reliability. In one design, a base station may send signaling to instruct at least one UE to receive control information on both a first control channel (e.g., a Physical Downlink control Channel (PDCCH)) and a second control channel (e.g., a Relay PDCCH (R-PDCCH)). The base station may send control information for the at least one UE on the first and second control channels, e.g., in different time and/or frequency regions of a subframe. In another aspect, control information may be sent on a control channel in multiple subframes with bundling to improve reliability. A user equipment (UE) may perform the complementary processing to recover the control information sent by the base station on multiple control channels or with bundling.

    摘要： Time division multiplexing (TDM) partitioning is one of the inter-cell interference coordination (ICIC) mechanisms considered for a heterogeneous network (HetNet) ICIC in a co-channel deployment. For example, in subframes that are pre-allocated to an evolved Node B (eNB), neighbor eNBs may not transmit, hence interference experienced by served user equipments (UEs) may be reduced. Semi-persistent scheduling (SPS) grants may have various available periodicities, which may not be compatible with TDM partitioning. Therefore, a UE may miss an SPS opportunity that was scheduled for a subframe that was not usable by the UE. Hence, using SPS grants with small periodicities in a heterogeneous network with TDM partitioning may require changes which may include adjusting the periodicities of the SPS grants, rescheduling of uplink SPS messages based on resource partitioning information (RPI), and/or determining RPI based on current SPS grants.

    摘要： Methods and apparatus for partitioning resources for enhanced inter-cell interference coordination (eICIC) are provided. Certain aspects involve broadcasting a message indicating time-domain resource partitioning information (RPI), where a user equipment (UE) may be operating in idle mode. With the RPI, the UE may be able to identify protected resources with reduced/eliminated interference from neighboring cells. The RPI in this broadcasted message may be encoded as a bitmap as an alternative or in addition to enumeration of the U/N/X subframes. Other aspects entail transmitting a dedicated or unicast message indicating the time-domain RPI, where a UE may be operating in connected mode. With the RPI, the UE may be able to determine channel state information (CSI), make radio resource management (RRM) measurements, or perform radio link monitoring (RLM), based on one or more signals from a serving base station during the protected time-domain resources.
