  • Patent number: 10674501
    Abstract: Methods, systems, and devices for wireless communication are described. A base station may indicate time and frequency resources for a low latency physical downlink control channel (sPDCCH), which may be different from another physical downlink control channel (PDCCH), to a user equipment (UE). The base station may then transmit a common sPDCCH (CsPDCCH) message to indicate which low latency control channel elements (sCCEs) are used for sPDCCH transmission during a given subframe. In some cases, the signaling used to indicate the initial resource allocation for sPDCCH may be infrequent relative to the CsPDCCH transmissions. If some of the resources initially allocated for sPDCCH are not actually used for sPDCCH during a subframe, the base station and the UE may use those resources for communicating data. For example, the base station may transmit data using a low latency physical downlink shared channel (sPDSCH) to the UE using those resources.

  • Patent number: 10666772
    Abstract: Novel tools and techniques might provide for implementing extension of customer local area networks (“LANs”) and/or implementing isolated service overlays over a network. In some embodiments, a network service point that is located external to a demarcation point at each of a plurality of customer premises might establish a connection between a service provider network and a customer LAN, which has already been established within a customer premises. The system subsequently extends the customer LAN, via this connection, to span between the network service point and the customer premises. Alternatively, or additionally, the system might establish two or more isolated service overlays across the customer LAN between the network service point and the customer premises, each of the two or more isolated service overlays having network traffic that is isolated from network traffic transmitted along another of the two or more isolated service overlays.

  • Patent number: 10645589
    Abstract: Systems and methods for adaptive method exploits self-interference suppression (SIS) and full-duplex (FD) capabilities in cognitive radio and dynamic spectrum access (DSA) systems to enable simultaneous transmission-and-sensing (TS) or transmission-and-reception (TR) over the same frequency channel in a single operation. The adaptive methods enable secondary users or units (SUs) to switch between different modes of operation, taking into account the primary units (PUs) state, the SUs' traffic, and standards' rules. These adaptive methods significantly enhance the SU throughput and reduce the probability of colliding with PU transmissions.

  • Patent number: 10631197
    Abstract: A system and method which improve the performance of a wireless transmission system by intelligent use of the control of the flow of data between a radio network controller (RNC) and a Node B. The system monitors certain criteria and, if necessary, adaptively increases or decreases the data flow between the RNC and the Node B. This improves the performance of the transmission system by allowing retransmitted data, signaling procedures and other data to be successfully received at a faster rate, by minimizing the amount of data buffered in the Node B. Flow control is exerted to reduce buffering in the Node B upon degradation of channel qualities, and prior to a High Speed Downlink Shared Channel (HS-DSCH) handover.
