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.

Optimized cell acquisition for LTE TDD systems or CSG/eMBMS capable UEs

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.

Achieving fast EMBMS channel switching and adding in LTE

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.

Optimized HARQ recombining within transmission window

In one example, a device includes one or more processors configured to determine that data for at least a portion of a segment of media data has been lost after a remaining portion of the segment has been received via a network transmission in accordance with dynamic adaptive streaming over HTTP (DASH), based on the determination, prior to decoding the media data, add default data to the segment to replace the data that has been determined to be lost to form a replacement segment, and output media data of the replacement segment.
