  • Systems and methods for data representation and transportation
    Patent number: 9894421
    Abstract: Systems and methods reduce redundancy in a data representation. The data is divided into a plurality of data portions. The data portions are used to encode a plurality of compressed data portions, wherein the compressed data portions correspond to a subset of the data portions and comprise less redundant data than the subset of the data portions. The compressed data portions are also encoded in accordance with data in the remaining data portions. The compressed data portions are transmitted instead of the subset of the data portions with the remaining data portions according to a sequence of data portions. Each of the compressed data portions is transmitted upon receiving an acknowledgment message that indicates successful transmission of a previous data portion or compressed data portion in the sequence of data portions.

  • Coordination of Wi-Fi P2P and LTE data traffic
    Patent number: 9894708
    Abstract: For LTE cellular data and Wi-Fi P2P technology coexistence scenario, a user equipment can generate in-device coexistence (IDC) indication message to the base station for DRX-based IDC solution. LTE data scheduling is described by a set of DRX parameters, while Wi-Fi P2P data scheduling is described by Opportunistic Power Saving (OppoPS) and Notification of Absence (NoA) parameters. When generating the IDC indication message for Wi-Fi P2P group client (GC), the DRX parameters must be selected carefully to maximize efficiency. Even though Wi-Fi shares less time, with proper time alignment, its coexistence performance could be better. For Wi-Fi P2P group owner (GO) with IDC TDM scheduling constraints, OppoPS and NoA should be aligned with DRX parameters to achieve best performance.
