  • Patent number: 11146476
    Abstract: In one embodiment, a copy of an original packet of a traffic flow is created at an ingress leaf node of a cloud switch. The ingress leaf node forwards the original packet along a less-specific path through the cloud switch, the less-specific path based on a domain index of an egress domain for the original packet. The copy of the original packet is modified to create a more specific path learn request packet. The ingress leaf node forwards the more specific path learn request packet along the less-specific path through the cloud switch. The ingress leaf node received back a more specific path learn request reply packet that includes an indication of a fabric system port. The ingress leaf node then programs a forwarding table based on the indication of the fabric system port, to have subsequent packets of the traffic flow forwarded along a more-specific path.

  • Patent number: 11115924
    Abstract: Multi-band Wake-up (MWU) signal transmission and detection is disclosed. A transmitter determines a MWU signal that indicates availability of one or more sub-bands to a first user in a serving cell, and transmits the MWU signal for the one or more sub-bands in the serving cell. A clear channel assessment (CCA) status on the one or more sub-bands that are available to the first user is carried by the payload of MWU signals. The MWU signal includes a first user identifier that identifies the first user as a targeted receiver of the MWU signal. The first user has priority over a second user to utilize the one or more sub-bands. Correspondingly, a receiver receives a MWU signal for one or more sub-bands in the serving cell, decodes a payload of the MWU signal, and determines availability of the one or more sub-bands to the first user based on the payload of the MWU signal.

  • Patent number: 11102689
    Abstract: Connection control circuitry is provided for a User Equipment (UE) configurable to offload communication of packet data from a cellular radio-access network comprising a Trusted Wireless Local Access Network (TWLAN) and a Trusted Wireless Access Gateway (TWAG) with IP Address preservation. The connection control circuitry has a connection requesting module configured to send a distinguishable-connection establishment message to the TWAG, requesting setup of a TWAG-routed data connection comprising at least one of a Packet Data Network (PDN) connection and a Non-Seamless Wireless Offload (NSWO) connection. A unique virtual gateway interface address is used to identify a point-to-point link between the UE and the TWAG. This allows the TWAG to distinguish between multiple substantially simultaneous point-to-point links which support multiple substantially simultaneous packet data connections. Other embodiments may be described and claimed.

  • Patent number: 11082329
    Abstract: The described technology is generally directed towards lossless delivery of data when there are route changes, e.g., in an integrated access and backhaul (IAB) multi-hop relay network. When a route changes is to occur, the last unchanged node in a multiple hop route preserves the data (e.g., copies unacknowledged and unsent PDCP PDUs from the protocol stack corresponding to the radio link control layer of the failed relay hop, and populates a replacement protocol stack for the node in the new route with the preserved data. Also described is pre-emptive detection of link failure, which triggers a route change based on monitoring retransmissions to detect a deteriorating link, which can occur before complete link communication failure.

  • Patent number: 11076417
    Abstract: This disclosure generally relates to downlink transmission scheduling for D2D UE based on subframe pattern. In one embodiment, the D2D UE may provide the BS with information on a pattern of the D2D reception subframes that indicates the usage of at least some of the D2D reception subframes. From the pattern, the BS may determine one or more D2D reception subframes in which the UE wants to monitor the D2D reception and/or the cellular reception. Then the BS may avoid scheduling the downlink transmission in the subframes in which the UE monitors the D2D reception. In the other D2D reception subframes, the downlink transmission can be scheduled. In this way, the UE can properly switch between the D2D reception and cellular reception, without any conflicts or downlink resource waste.

  • Patent number: 11070631
    Abstract: A terminal device, for example a 3GPP Proximity Services (ProSe)-enabled user equipment, obtains imprecise location information relating to a location of the terminal device, and transmits a proximity service discovery message, wherein the discovery message includes the imprecise location information. A second terminal device, again for example a 3GPP Proximity Services (ProSe)-enabled user equipment, receives a proximity service discovery message containing location information. The second terminal device obtains location information relating to its location, and calculates a distance from the location indicated by the location information in the received discovery message to its location. The second terminal device acts on the received discovery message only if the calculated distance is less than a predetermined distance.

  • Patent number: 11039425
    Abstract: Methods, systems, and devices for wireless communication employing polar code techniques are described. In some examples, polar codes with a cross-referenceable nested structure for hierarchical signaling may be used in a wireless communication system. For example, a user equipment may monitor a common portion and a dedicated portion of a control channel, the common portion assigned to a first set of control channel resources and the dedicated portion assigned to a second set of control channel resources within the control channel. The UE may concatenate, based at least in part on the monitoring, information fields of one or more symbols received via the first and second sets of control channel resources to form a polar-encoded codeword. The UE may decode the polar-encoded codeword to obtain common information from the common portion and dedicated information from the dedicated portion.

  • Patent number: 11019547
    Abstract: A method and system to control UE handover is disclosed herein. A source base station serving a UE receives from the UE a measurement report that specifies a signal strength of a neighboring target base station. The source base station sets a value of a handover threshold parameter, with the set value being based at least in part on whether the target base station is a relay base station or a non-relay base station. Further, the source base station may compare the specified signal strength of the target base station to the set value of the handover threshold parameter and determine that a handover condition is satisfied. Responsive to making such a determination, the source base station may invoke handover of the UE from the source base station to the target base station.
