  • Patent number: 9749078
    Abstract: Techniques, apparatus and systems are described for accommodating the optical network units (ONUs) having different nominal upstream bitrates on the same passive optical network (PON) system by making the specified burst preamble and the bandwidth map allocation record format invariant with respect to the nominal upstream bitrate of a target ONU. The disclosed techniques, apparatus and systems allow seamless evolution of the lower-bitrate services to higher-bitrate services offered to an end-user without need to upgrade the central office equipment. In addition they can avoid the adverse consequences of inadvertently connecting a high-upstream-bitrate ONU to a lower-upstream-bitrate network.

  • Patent number: 9706333
    Abstract: In a machine to machine (M2M) communication network comprising M2M application servers and M2M nodes such as M2M devices and gateways, applications that are specific to different M2M Service Providers (SPs) may be hosted. Different services are provided by different M2M Service Providers, while being hosted on a single Home Gateway, by the use of sensing and actuation equipment for different services. The home gateway may typically be owned by a home owner while some equipment may be services-specific and not owned by the home owner. Interfaces are provided enabling individual services providers to independently control resources allocated to their services hosted on the M2M node.

  • Patent number: 9635652
    Abstract: A method of transmitting data from a UE to an eNB is provided. In response to a data transmission request from a MTC application, the UE chooses a preamble ID based on the data size and transmits a random access preamble message to the eNB. The eNB returns a random access response message to the UE. The random access response message identifies resource allocated in an uplink channel and includes one or more transmission power control parameters associated with the second uplink channel. After determining that the data size is less than or equal to the allocated resources in the second uplink channel, the UE transmits a scheduled transmission message to the eNB using the allocated resource in the second uplink channel at a transmission power level determined by the one or more transmission power control parameters.

  • Patent number: 9532350
    Abstract: Enhanced physical downlink control channel are multiplexed with physical downlink data channel in frequency division multiplexing (FDM), or in frequency division multiplexing (FDM)+time division multiplexing (TDM). FDM mode applies to users that have only UL grants in that subframe. UL grants of different users are cross-interleaved and transmitted over the entire physical resource blocks (both slots) in FDM. Frequency resources for cross-interleaved UL grants are distributed. TDM+FDM applies to users that have both DL and UL grants, or have only DL grant in that subframe. DL/UL grant (maybe mixed) is transmitted only in the first slot of physical resource blocks in TDM+FDM, where the second slots in those resource blocks can be used for those users' downlink data transmission.
