  • Publication number: 20190281520
    Abstract: A device is provided for operating in a communication system that comprises a plurality of individual networks. The device comprises one or more subscriber modules for assisting the device to attach to a network. The number of those one or more subscriber modules is fewer than the number of the plurality of networks. The device being configured to initiate a pre-attach procedure to attach itself to all of the plurality of networks before it establishes a connection with one of those networks. It is also configured to connect to one of the plurality of networks for communicating data with that network while remaining attached to the others of the plurality of networks. The advantage of a device that pre-attaches to more than one network is that it significantly reduces the time needed for the device to switch later from being connected to one network to another network.

  • Publication number: 20190230480
    Abstract: A relay device for operating in a communication system that comprises at least two individual networks. The networks may be “individual” in the sense that they are different from each other. Different networks comprise different functionalities. In particular, different networks will tend to operate in different spectrum, have separate authorization and/or authentication procedures and/or apply different transmission technologies. Each network comprises a network device and a remote device that are configured to wirelessly transfer data between them. The relay device is configured to receive data transmitted by a device in a first one of the networks over a first section of radio spectrum. It is also configured to transmit that data to a device in a second one of the networks over a second section of radio spectrum that is different from the first section of radio spectrum.

  • Publication number: 20190132887
    Abstract: The present invention relates to a random access scheme exhibiting a non-isometric frame duration and a low latency. The RA and data messages have a duration with a different time unit and the time slot of the RA message is much shorter than the duration of one data frame. A specific signature, which is designed to be robust against the collisions, is transmitted during the RA request, the signature being either a unique sequence or a compressed signature. The user equipment device transmits the data message immediately after receiving its resource through a frame structure showing a time misalignment between adjacent data frames located in different or identical frequency sub-bands. A frequency guard band is inserted between its resource and an adjacent resource assigned to another user equipment device, the frequency guard band having an adaptive size according to the level of time misalignment and its impact on the distortion.
