  • Optimized cell acquisition for LTE TDD systems or CSG/eMBMS capable UEs
    Patent number: 9826419
    Abstract: Techniques for optimized cell acquisition for long term evolution (LTE) time division duplex (TDD) systems or closed subscriber group (CSG)/evolved Multicast Broadcast Multimedia Service (eMBMS) capable user equipments (UEs) are disclosed. A UE obtains configuration information, CSG capability information, and/or eMBMS capability information for a cell. The UE also stores the obtained information for the cell in a cell information database. In some aspects, the UE may employ the CSG and/or eMBMS capability information to select a weaker cell, during initial frequency scan at power up of the UE, based on cell capability. Additionally or alternatively, the UE may employ the configuration information to determine an initial mutual information (Mi) hypothesis value for physical hybrid-automatic repeat request (HART) indicator channel (PHICH) group mapping of the cell.
