摘要： A method for power control in a long term evolution (LTE) network is disclosed and includes configuring a user equipment (UE) with a plurality of transmit power levels where each transmit power level corresponds to a subframe type. A first power level is used in subframes protected by cooperative coordination between base stations. A second power level corresponds to unprotected subframes. The method also includes scheduling the UE to transmit in accordance with the configured transmit power levels.

摘要： Techniques for estimating and reporting channel quality indicator (CQI) are disclosed. Neighboring base stations may cause strong interference to one another and may be allocated different resources, e.g., different subframes. A UE may observe different levels of interference on different resources. In an aspect, the UE may determine a CQI for resources allocated to a base station and having reduced or no interference from at least one interfering base station. In another aspect, the UE may determine multiple CQI for resources of different types and associated with different interference levels. For example, the UE may determine a first CQI based on at least one first subframe allocated to the base station and having reduced or no interference from the interfering base station(s). The UE may determine a second CQI based on at least one second subframe allocated to the interfering base station(s).

摘要： Methods and apparatus for processing channel quality information (CQI) and scheduling resources subject to cooperative resource allocation based on the CQI are provided. To convey the CQI for protected/unprotected subframes in a single report, a new vector CQI format may be utilized. Two alternatives for CQI processing this vector format and the advantages of each are described. In the first alternative, a single entry from the CQI vector is selected for processing by a downlink scheduler and/or other media access control (MAC) blocks (e.g., a PHICH, DCI power control, and/or PDCCH scheduler). In the second alternative, the selection from the CQI vector is made on a per-subframe basis, and both the subframe and the selected CQI element are processed by the downlink scheduler and/or the other MAC blocks. In this manner, better scheduling decisions may be made using the CQI vector.

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 apparatuses are provided that include mitigating interference for devices communicating with femto nodes or other low power base stations by assigning protected resources for communicating therewith. The protected resources can be negotiated with a macrocell base station using interference cancellation. The protected resources can be assigned based on an early or late handover event, which can indicate that the device may be susceptible to interference from the macrocell base station.
