  • Patent number: 11116063
    Abstract: A load control system may include a load control device for providing power to an electrical load and a control device that may send instructions to the load control device for providing the power to the electrical load. The control device may communicate with the load control device using a link address assigned to the load control device. The load control device may provide power to the electrical load in a manner that causes the electrical load to indicate the link address assigned to the load control device. The link address may be identified by a user or a user device. The identified link address may be associated with a load control device identifier that may identify a physical location of a load control device that is assigned the link address. A user may control a load control device at a physical location by sending instructions via the link address.

  • Patent number: 10986689
    Abstract: A method, mobile device (101) and radio access network RAN (102) are disclosed for suspending and re-establishing a radio resource control (RRC) connection. In some examples, the mobile device (101) indicates a preference to have the RRC connection either suspended or released. In other examples, RAN (102) sends to the mobile device (101) a connection suspend command message instructing the mobile device to suspend a RRC connection with the RAN (102). The mobile device (101), in response to the connection suspend command message, suspends the RRC connection. When the RRC connection is suspended the mobile device (101) cannot transmit or receive user plane data to the RAN (102) and performs functions the same as or similar to idle mode functions. On suspension, RRC connection information is stored and can be used to re-establish the suspended RRC connection.

  • Patent number: 10812237
    Abstract: In mixed numerology case, the performance of a physical downlink shared channel (PDSCH) can be improved by multiplexing PDSCH of one numerology with the channel state information reference signals (CSI-RS) of the other numerology and use of an advanced receiver. However, due to the interference from the PDSCH of the other numerology, the channel estimation for the underlying UE can be impacted if the CSI-RS is corrupted. An adaptive CSI-RS configuration can be deployed where the CSI-RS density is adapted based on the PDSCH transmission of the other numerology. Namely, based on the scheduling decision of the other numerology, the CSI-RS density can be changed. Thus, the impact on channel estimation can be minimized when the data channel of one numerology is multiplexed with the CSI-RS of the other numerology.

  • Patent number: 10735165
    Abstract: Devices and methods for transmitting information in resource blocks between a base station and one or more communication devices are disclosed. In each resource block (RB) used for a data or control channel transmission, a plurality of non-overlapping regions of resource elements (REs) are defined. Each region is associated with one or multiple unique reference symbols (RSs), and may be further associated with one or more antenna ports. When user equipment (UE) demodulates the information it receives in a particular region of an RB, it uses the RS and/or antenna port associated with that region. The RS and/or antenna port information may be used, for example, to estimate a channel of the communication network or to demodulate and decode the data contained within the associated regions.

  • Patent number: 10715455
    Abstract: In one embodiment, for each distribution period of time, each packet flow is assigned to a path through a packet switching device (e.g., switch fabric) with all packets of the packet flow being sent in order over the assigned path. For a next distribution period, different paths are assigned for these packet flows, with all packets being sent in order over the new corresponding selected path. In one embodiment, these paths are switched often enough to prevent congestion, yet infrequent enough so as to minimize resources for reordering. In one embodiment, the reordering is done at the egress and only for predefined high bandwidth flows (e.g., elephant flows). A distribution period indication is typically associated with each packet to identify its corresponding distribution period. In one embodiment, each routing and egress switching stage in a switching fabric performs reordering.
