    摘要: A system and method are provided to selectively increase the reliability for transmission of select data packets that are determined to be important or critical. When the data packets are PDUs arranged in PDU-SETs, a user plane function (UPF) receives the PDU-SETs from a content server, and, based on header information, e.g., the UPF filters the PDU-SETs according to respective reliability levels. For PDU-SETs in the highest reliability level, a manner of transmitting the PDU-SETs is modified to increase reliability of the transmission for at least part of the transmission path. For example, the redundancy of the PDUs in the PDU-SETs can be increased for one or more legs of the transmission path by generating duplicates of the PDUs, which are transmitted together with the original PDUs. Further, reliability can be increased for respective legs by transmitting the PDUs using an acknowledgement mode.

    摘要: Systems and methods to support Physical Uplink Shared Channel (PUSCH) multi-Transmission/Reception Point (TRP) scheduling are provided. In some embodiments, the wireless device performs one or more of: obtaining a configuration for Transmission Configuration Indicator (TCI) states for Uplink (UL) PUSCH scheduling; activating/deactivating a subset of configured TCI states). If two TCI states are indicated, the wireless device transmits two different PUSCHs each corresponding to one of the indicated TCI states. If one TCI state is indicated, the wireless device transmits a single PUSCH corresponding to the indicated TCI state. The wireless device maps indicated TCI states to the transmission occasions or actual repetitions is preconfigured via higher layer parameter(s) or is given by a predefined rule. The wireless device applies a Transmitted Precoding Matrix Indicator (TPMI) to transmission occasions or actual repetitions associated with each indicated TCI state based on a signaled value and/or a predefined value.

    摘要: The described techniques address the issues of latency and lengthy processing times associated with conventional redundant sensor measurement systems that rely upon digital transmission protocols by implementing a diverse analog sensor interface architecture. The described architecture may advantageously use a number of sensor measurement paths that may be independent of one another or share any suitable number of common components to provide varying levels of redundancy. The analog interfaces may provide signal diversity with respect to the use of different types of analog transmission protocols, which may include different signaling interfaces (e.g. differential versus single-ended), different transmission interfaces (e.g. voltage versus current interfaces), and/or the use of different signalization schemes.

    摘要: A method of operating a transmission system (1) having a first network (2) and at least one second network (3) where data is exchanged between these at least two networks (2, 3) in that data of the first network (2) is fed to duplicating means (4), then is transmitted wirelessly to separating means (5) via at least two transmission paths (6, 7) by PRP, and is forwarded by the separating means (5) to the connected second network (3), characterized in that the data is transmitted via the first transmission path (6) as data packets and, if a data packet was not transmitted, this data packet is retransmitted via at least the second transmission path (7).
