  • Patent number: 11146985
    Abstract: An SDN architecture, for a cellular communications system, is described herein that includes a Quality of Service (QoS) provisioning framework to provision and manage traffic flows in the cellular communications system. The described architecture separates the control plane and the user plane for the transport of the user plane traffic. Network entities in the SDN architecture, such as a network controller, can detect and react to changes in network state (e.g., load conditions) to route or reroute traffic flows in the network. QoS and routing parameters may be determined for the network traffic on a per-flow basis, even when multiple flows are associated with a single service request.

  • Patent number: 11050504
    Abstract: A base station can obtain channel quality conditions for mobile devices in a scheduling interval and identify a channel quality, a target transmission scheme, and a transmission power level for each of the mobile devices. The base station can assign a unique orthogonal CDMA code and can force the mobile devices to transmit K repeated bursts of uplink data such that each of the mobile devices has a rotated phase shift based on the unique orthogonal CDMA code assigned to each of the mobile devices with each of the mobile devices multiplexed on a same physical channel using an overlaid CDMA operation. The base station can process K repeated bursts that are multiplexed on the same physical channel using the overlaid CDMA operation. The base station can separate the mobile devices according to the unique orthogonal CDMA code and use IQ accumulation according to combine the K repeated bursts.

  • Patent number: 11006259
    Abstract: Briefly, in accordance with one or more embodiments, a fixed device synchronizes with a downlink channel of a network, acquires a master information block including a last system update time; and executes cell selection without acquiring other system information if the last system update time is before the last system access time. Furthermore, the fixed device may listen only for system information block messages that it needs, and ignore other system information blocks. A bitmap may indicate which system information block messages should be listed to for fixed devices, and which may be ignored. In some embodiments, one or more system information blocks may be designated for fixed devices.

  • Patent number: 10863585
    Abstract: Embodiments of an access point (AP), station (STA), and method of communication are generally described herein. The AP may perform channel sensing in a first channel of a first frequency band and a second channel of a second frequency band to obtain access for transmission of a physical layer convergence procedure (PLCP) protocol data unit (PPDU) that comprises multiple subframes. The transmission of the PPDU may be configurable to use a multi-band layer-1 aggregation of the first and second channels. While the second channel is unavailable, the AP may transmit one or more subframes on the first channel without usage of the multi-band layer-1 aggregation. When it is determined that the second channel has become available, the AP may switch to synchronized transmission of the subframes on the first and second channels in accordance with the multi-band layer-1 aggregation.
