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. Additionally or alternative, radio link failures and/or out of synch events may be predicted and proactive responses employed based on previously obtained solutions.

Abstract: Techniques for optimized HARQ recombining are provided. In one exemplary embodiment, a method for wireless communication comprises receiving a broadcast message to determine a timing of a transmission window, receiving at least one transmission within the transmission window, and determining whether the at least one transmission is successfully decoded. The method further comprises instructing a lower protocol layer to ignore remaining transmissions within the transmission window upon a determination that the at least one transmission is successfully decoded, wherein the remaining transmissions and the at least one transmission comprise duplicate copies of a message segment.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives a first MTCH. The apparatus stores MBMS control information for at least a second MTCH. The apparatus subsequently determines to receive the second MTCH. The apparatus then accesses the stored MBMS control information for the second MTCH upon determining to receive the second MTCH. The apparatus receives the second MTCH based on the accessed MBMS control information without acquiring the MBMS control information for the second MTCH after the determination to receive the second MTCH.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for decoding Multimedia Broadcast and Multicast Service (MBMS) data. A User Equipment (UE) may receive a Multicast Control Channel (MCCH) and Multicast Channel Scheduling Information (MSI) in a same subframe of a scheduling period, the MCCH and the MSI relating to one or more MBMS services provided in a Multimedia Broadcast Single Frequency Network (MBSFN) area. The UE may configure at least a first control layer for the one or more MBMS services based on the MCCH and retain the MSI at least until the configuring is complete. The UE may thereafter configure at least a second control layer for the one or more MBMS services based on the MSI.
