  • Patent number: 10674457
    Abstract: Logic may comprise hardware and/or code to coordinate communications of wireless communications devices to reduce power consumption by stations. Logic may coordinate communications in an access point. Logic may generate and transmit a wake frame from the access point to the station to wake the receive circuitry of the station. Logic of the station may wake the receive circuitry from an idle mode, which may be a less linear and less sensitive mode, to a receiver (RX) active state, which is a high linear and high sensitivity mode. Once the receiver circuitry enters the RX active state, the station is ready to receive a transmission. Logic may implement the wake frame as a medium access control frame or as a null data packet, physical layer frame.

  • Patent number: 10623194
    Abstract: A novel method of conducting multicast traffic in a network is provided. The network includes multiple endpoints that receive messages from the network and generate messages for the network. The endpoints are located in different segments of the network, each segment including one or more of the endpoints. For a source endpoint to replicate a particular message (e.g., a data packet) for all endpoints belonging to a particular replication group (i.e., multicast group) within the network, the source endpoint replicates the particular message to each endpoint within the source endpoint's own segment and to a proxy endpoint in each of the other segments. Each proxy endpoint in turn replicates the particular message to all endpoints belonging to the particular replication group within the proxy endpoint's own segment.

  • Patent number: 10623067
    Abstract: Various embodiments disclosed herein provide for an enhanced timing advance scheme to support MU-MIMO in an integrated access and backhaul system. The timing advance scheme disclosed herein aligns the arrival time between backhaul links and access links to enable MU-MIMO gain at the receiver side. In the integrated access and backhaul system, which comprises distributed nodes, the timing advance offset for an access link transmission (a transmission to a node further away in hops from the core network, or to a user equipment device) can be modified by offsetting it with the timing advance of the backhaul link (e.g., from a parent node). This enables the arrival time for transmissions, both access link transmissions from the UE or child node, and backhaul link transmissions from a parent node to arrive at the same time.

  • Patent number: 10567130
    Abstract: An access node of the wireless communication network determines a configuration of a first search space (210) in terms of first time domain coordinates and first frequency domain coordinates of a time-frequency grid of radio resource elements. Further, the access node determines a configuration of a second search space (220) in terms of second time coordinates and second frequency domain coordinates of the time-frequency grid. The second search space (220) differs from the first search space at least with respect to the time domain coordinates. In radio resource elements of the first search space (210), the access node transmits downlink control information for a first class of radio devices subject to a first timing requirement. In radio resource elements of the second search space (220), the access node transmits downlink control information for a second class of radio devices subject to a second timing requirement which is stricter than the first timing requirement.
