  • Patent number: 9730128
    Abstract: A method, an apparatus, and a computer program product for wireless communication enable user equipment operating in a current cell that provides a multimedia broadcast/multicast service to distinguish between neighboring cells that have different operational characteristics. The presence of a neighboring cell is identified while the user equipment is operating in a first cell and it is determined whether the neighboring cell provides services different from the services provided in the current cell, based on information maintained by the user equipment. The user equipment may move to the neighboring cell to obtain better or different service.

  • Patent number: 9668206
    Abstract: Techniques for multiplexing and transmitting multiple data streams are described. Transmission of the multiple data streams occurs in “super-frames”. Each super-frame has a predetermined time duration and is further divided into multiple (e.g., four) frames. Each data block for each data stream is outer encoded to generate a corresponding code block. Each code block is partitioned into multiple subblocks, and each data packet in each code block is inner encoded and modulated to generate modulation symbols for the packet. The multiple subblocks for each code block are transmitted in the multiple frames of the same super-frame, one subblock per frame. Each data stream is allocated a number of transmission units in each super-frame and is assigned specific transmission units to achieve efficient packing. A wireless device can select and receive individual data streams.

  • Publication number: 20170006249
    Abstract: Systems and methods which provide enhanced isolation for receivers using relatively simple and inexpensive modifications or additional circuitry at a receiving station. Embodiments augment a primary antenna of a receiving station with a correlated heterogeneous antenna element. Augmented antenna systems of embodiments provide an appreciable increase in front-to-back isolation with respect to desired signals received at a receiving station. Such augmented antenna systems are particularly useful in a high interference environment, such as an interference limited environment as may be experienced at the edge of two Single Frequency Networks (SFNs). For example, embodiments of an augmented antenna system may be utilized in situations in which positive carrier to noise ratio (C/N) conditions are present (e.g., more signal than noise is present in the desired signal and more signal than noise is present in the interfering signal).

  • Patent number: 9521411
    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.

  • Patent number: 9473967
    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.

  • Publication number: 20160266231
    Abstract: Systems and methods are provided for determining position location information in a wireless network. In one embodiment, timing offset information is communicated between multiple transmitters and one or more receivers. Such information enables accurate position or location determinations to be made that account for timing differences throughout the network. In another embodiment, transmitter phase adjustments are made that advance or delay transmissions from the transmitters to account for potential timing differences at receivers. In yet another embodiment, combinations of timing offset communications and/or transmitter phase adjustments can be employed in the wireless network to facilitate position location determinations.

  • Publication number: 20160226608
    Abstract: Methods and systems simplify discovery and handoff for multi-frequency broadcast receiver devices, such as mobile TV devices, by providing a virtual home channel that is not dependent on a single frequency network upper layer. The methods and systems may be used in conjunction with a single frequency network upper layer to support areas without upper layer available, or to off load some portion of the common data bandwidth in the single frequency network. For example, the single frequency network may only carry frequency data for the multiple frequency network or only the frequency data for networks with comprehensive market metadata.
