Abstract: Embodiments provide methods and systems for transmitting an emergency (SOS) message from a user (UE) to a cellular network in a highly robust and energy efficient manner. Specifically, embodiments enable the SOS message to be sent in a synchronous manner despite the asynchronous nature of the network, which significantly enhances the probability of successful reception of the SOS message by at least one base station (eNodeB) of the network. Embodiments further provide highly robust SOS message transmission and reception schemes configured to enhance the successful detection and decoding of the SOS message by at least one base station of the cellular network. In addition, embodiments enable the synchronous transmission of the SOS message to the network without requiring network attachment by the UE. This makes embodiments highly suited for emergency situations in which network coverage is affected and can enable significant and precious power savings at the UE.
Abstract translation: 实施例提供了用于以高度鲁棒且高能效的方式从用户（UE）向蜂窝网络发送紧急（SOS）消息的方法和系统。 具体地，实施例使得SOS消息能够以同步方式发送，尽管网络的异步性质，这显着增强了由网络的至少一个基站（eNodeB）成功接收SOS消息的概率。 实施例还提供了高度鲁棒的SOS消息传输和接收方案，其被配置为增强蜂窝网络的至少一个基站对SOS消息的成功检测和解码。 此外，实施例能够使SOS消息同步传输到网络，而不需要UE的网络连接。 这使得实施例非常适合于其中影响网络覆盖的紧急情况，并且可以在UE处实现显着和宝贵的功率节省。

Abstract: A technique to receive a Multimedia Broadcast Multicast Service (MBMS) broadcast, in which a plurality of source symbols and repair symbols of a broadcast from a broadcast source are received at a UE. The source symbols and repair symbols are based on fountain codes, so that not all of the repair symbols are used to recover the originally sourced data. An application layer of the UE recovers the sourced data and places the receiver in a power-save mode following the last repair symbol used to recover the sourced data, so that remaining repair symbols are not received by the receiver and subsequently processed.
Abstract translation: 一种用于接收多媒体广播多播服务（MBMS）广播的技术，其中在UE处接收来自广播源的广播的多个源符号和修复符号。 源符号和修复符号基于喷泉代码，因此并不是所有修复符号都用于恢复原始来源的数据。 UE的应用层恢复源数据，并将接收机放置在按照用于恢复来源数据的最后修复符号之后的省电模式，使得剩余的修复符号不被接收机接收并随后处理。

Abstract: The present disclosure is directed to a system and method for encoding k input symbols, using a Reed-Solomon erasure correction code, into a longer stream of n output symbols for transmission over an erasure channel. The present disclosure is further directed to a system and method for recovering the original k input symbols from only (and any) k output symbols (out of the n output symbols) received over the erasure channel. A symbol is a generic data unit consisting of one or more bits that can be, for example, a packet. The systems and methods of the present disclosure provide for an adjustable code rate that can be readily adapted based on changing channel conditions without having to reconstruct the encoder/decoder. As a result, such an encoder/decoder can be referred to as rate-independent.
Abstract translation: 本公开涉及一种用于使用Reed-Solomon消除校正码将k个输入符号编码到较长的n个输出符号流中以便在擦除信道上传输的系统和方法。 本公开进一步涉及用于仅从通过擦除信道接收的（和任何）k个输出符号（在n个输出符号中）恢复原始k个输入符号的系统和方法。 符号是由一个或多个比特组成的通用数据单元，其可以是例如分组。 本公开的系统和方法提供了可以基于改变信道条件容易地适应的可调节码率，而不必重建编码器/解码器。 结果，这样的编码器/解码器可以被称为速率无关。

Abstract: Embodiments provide WiFi and LTE tailored transceiver radio frequency (RF) filtering techniques and configurations to enable coexistence between WiFi and LTE transceivers operating in close proximity. In particular, embodiments provide filtering techniques to reject emissions from LTE into WiFi, and vice versa. The filtering techniques eliminate the need for additional isolation between LTE and WiFi antennas (approximately 50 dB), which is beyond what is achievable in practice. Embodiments can be tailored according to different use cases of the WiFi and LTE transceivers (e.g., fixed CPE, portable router, smart phone with tethering).
Abstract translation: 实施例提供WiFi和LTE定制的收发射频（RF）滤波技术和配置，以实现在接近操作的WiFi和LTE收发器之间的共存。 具体地，实施例提供了滤除技术来拒绝从WiFi到WiFi的发射，反之亦然。 滤波技术消除了LTE和WiFi天线之间的额外隔离（约50 dB）的需要，这超出了实际可实现的范围。 可以根据WiFi和LTE收发器（例如，固定CPE，便携式路由器，带有束缚的智能电话）的不同用例来定制实施例。
