Abstract: An Encoder Assisted Frame Rate Up Conversion (EA-FRUC) system that utilizes video coding and pre-processing operations at the video encoder to exploit the FRUC processing that will occur in the decoder in order to improve compression efficiency and reconstructed video quality is disclosed. One operation of the EA-FRUC system involves determining whether to encode a frame in a sequence of frames of a video content by determining a spatial activity in a frame of the sequence of frames; determining a temporal activity in the frame; determining a spatio-temporal activity in the frame based on the determined spatial activity and the determined temporal activity; determining a level of a redundancy in the source frame based on at least one of the determined spatial activity, the determined temporal activity, and the determined spatio-temporal activity; and, encoding the non-redundant information in the frame if the determined redundancy is within predetermined thresholds.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. An apparatus, e.g., user equipment (UE), receives a reporting requirement for one or more Multicast-Broadcast Single Frequency Network (MBSFN) physical layer parameters. The UE obtains the one or more MBSFN physical layer parameters including at least one parameter corresponding to a reference signal, and creates a report based on the obtained one or more MBSFN physical layer parameters. The UE may obtain the one or more MBSFN physical layer parameters using user-plane or control-plane based mechanisms. The user-plane mechanism involves the use of a modified version of the reporting mechanism for Quality of Experience (QoE) metrics. The control-plane mechanism involves the use of a modified version of the reporting mechanism for the Minimization of Drive Tests (MDT) metrics.

Abstract: Diversity enhancement for multiple carrier systems is disclosed which includes generation of a multiplexed multicarrier radio frequency (RF) signal having N carriers organized to be accessed at a rate of one carrier access per multicast channel (MCH) scheduling period (MSP) per carrier of the N carriers, thereby requiring N accesses per MSP duration across the N carriers. The method may also include the base station transmitting the RF signal to a user equipment (UE). In other aspects, the diversity enhancements include the UE receiving a multiplexed multicarrier RF signal having N carriers. The UE may access the N carriers by performing one carrier access per MSP per carrier of the N carriers, thereby performing N accesses per MSP duration across the N carriers.

Abstract: Extended duration cyclic prefixes with lower overhead are disclosed in which an integer multiple sequence of carriers above the nominal 300 carrier-per-25 resource blocks (RBs) definition are selected to reduce the cyclic prefix overhead below the normative 20%. Sets of durations are then provided associated with each such integer multiple sequence of carriers that allow for the combined duration of the symbol duration and extended duration cyclic prefix to result in an integer number of carriers for each RB.
