  • Publication number: 20180014192
    Abstract: Systems, methods, and instrumentalities are disclosed that provide for a gateway outside of a network domain to provide services to a plurality of devices. For example, the gateway may act as a management entity or as a proxy for the network domain. As a management entity, the gateway may perform a security function relating to each of the plurality of devices. The gateway may perform the security function without the network domain participating or having knowledge of the particular devices. As a proxy for the network, the gateway may receive a command from the network domain to perform a security function relating to each of a plurality of devices. The network may know the identity of each of the plurality of devices. The gateway may perform the security function for each of the plurality of devices and aggregate related information before sending the information to the network domain.

  • Publication number: 20170026163
    Abstract: The invention involves utilizing pieces of disjoint spectral blocks. In one embodiment, a frequency division duplex approach is used, where each spectral block is utilized solely for either uplink or downlink communications. In another embodiment, a time division duplex approach is used, where each spectral block is time divided and uplink and downlink communications are assigned to different time slots within the same spectral blocks. In another embodiment, a code division duplex approach is utilized, where uplink and downlink communications are assigned different codes/hopping patterns within a same spectral block.
