  • Patent number: 11026154
    Abstract: A wireless network comprises nodes, including routers having a tree-shaped communication topology and end devices, communicate in accordance a network protocol, wherein the routers transmit beacons in respective timeslots within a periodic beaconing interval, passively scan for messages, and, in response to receiving a message, transmit an acknowledgement thereof the received message. An end device that has a message that is pending transmission, passively scans for beacons transmitted from any router; and in response thereto, transmits the message, and passively scans for an acknowledgement, repeating those steps if no acknowledgement is received. This provides responsivity in an environment having rapidly changing propagation paths. To reduce power consumption, the end devices do not passively scan for beacons except when they have a message that is pending transmission, and also at predetermined times for reception of a downstream message.

  • Patent number: 11026171
    Abstract: A wireless device starts a deactivation timer of a secondary cell based on receiving a MAC command indicating activation of the secondary cell. The deactivation timer is restarted in response to receiving a first DCI comprising: a first field indicating an uplink resource block assignment; and a first trigger field indicating that the first DCI is triggered in response to a second trigger of a second DCI. The second DCI is received and comprises: a second trigger field indicating the second trigger; and a second field indicating a subframe offset value. The deactivation timer is restarted in response to receiving the second DCI. In response to the second trigger, transport block(s) are transmitted using the uplink resource block assignment of a subframe. A position of the subframe is determined based on the subframe offset value.

  • Patent number: 11018813
    Abstract: A terminal receives downlink scheduling information of a downlink subframe F(i, j), where a set M of preconfigured downlink subframes in which the downlink subframe F(i, j) is located is divided into N subsets of preconfigured downlink subframes, a bit quantity of a hybrid automatic repeat request-acknowledgement HARQ-ACK that needs to be fed back for each downlink subframe in one subset of preconfigured downlink subframes is a predetermined value, and bit quantities of HARQ-ACKs that need to be fed back for any downlink subframes in different subsets of preconfigured downlink subframes are different. The terminal generates a HARQ-ACK codebook according to a receiving status of downlink data. And the terminal generates uplink control information after encoding the HARQ-ACK codebook; and a sending module sends the uplink control information.

  • Patent number: 11019596
    Abstract: When mobile terminated devices sleep, the devices might not be reachable when needed, for instance when the device is a recipient of data from a third party server. As described herein, a third party application server may inform the network that it has data to send to a particular UE or group of UEs. In an example, the mobile core network (MCN) may use information from the third party server to ensure that the UE is awake when it needs to be. For example, a given UE or group of UEs can be prevented from entering a sleep state before a data transfer is completed.

  • Patent number: 11019660
    Abstract: In 802.11ax networks with access points, a trigger frame offers scheduled and random resource units to nodes for data uplink communication to the access points. To make more effective the usage of the network, the access point may design the trigger frame to force the nodes to send some categories of data. Resource units may be defined in trigger frames to be dedicated to small packets or to some access category data. Adjusting the time length of the resource units helps restricting the type of data that can be conveyed by the resource units. Also, using various frequency widths for resource units in the same trigger frame helps reducing padding in the resource units when various traffic types coexist.

  • Patent number: 11013056
    Abstract: Aspects of the disclosure relate to mechanisms for dynamic prioritization of uplink (UL) traffic at a user equipment (UE). In some examples, the UE may determine to delay transmission of UL traffic by skipping one or more UL transmission opportunities based on one or more factors, such as a power saving indication, a priority level of the UL traffic, a type of the UL traffic, a volume of the UL traffic, and/or current channel conditions. In some examples, the UE may be configured with a parameter controlling the ability of the UE to delay a transmission of UL traffic. In some examples, when the UE is operating in a semi-persistent scheduling mode and a power saving mode, such as a connected mode discontinuous reception (C-DRX) mode, the UE may dynamically interrupt an OFF duration of the C-DRX cycle to transmit UL traffic.
