  • Gap enhancements in wireless networks
    Patent number: 11690054
    Abstract: Aspects relate to enhancing the provision of gaps at transitions between resources allocated for communication on access links and resources allocated for communication on backhaul links. In some examples, a child integrated access backhaul network (IAB) node may transmit a message to a parent IAB node requesting a number of guard symbols to provide a gap at transitions. In some examples, the parent IAB node may transmit the number of guard symbols provided at transitions to the child IAB node. The parent IAB node, child IAB node, and/or an IAB donor node central unit may further identify a subcarrier spacing associated with the number of guard symbols.

  • Managing a backhaul configuration in a wireless multi-hop network
    Patent number: 11672031
    Abstract: A first control node may communicate with a user equipment (UE) using an integrated access and backhaul (IAB) network, and a second control node may manage a configuration of the IAB network. The second control node may not have the information needed to configure the IAB network, such as quality of service (QoS) information associated with a data radio bearer (DRB) used for communications between the first control node and the UE, and thus may not be able to configure a user plane interface tunnel and/or a radio link control (RLC) channel to assist with satisfying the QoS level. Some techniques and apparatuses described herein enable the second control node to receive QoS information associated with setting up a user plane interface tunnel between the first control node and an IAB node that serves a UE for which the user plane interface tunnel is being set up.

  • Beam optimization for soft physical cell identifier change
    Patent number: 11659413
    Abstract: Aspects of disclosure relate to a network node for changing a physical cell identifier (PCI). The network node transmits a first signal based on a first PCI during a first synchronization signal block (SSB) occasion, transmits a second signal based on the first PCI during a second SSB occasion, and transitions from the first PCI to a second PCI. During a transition period, the network node transmits the first signal based on the second PCI during the first SSB occasion, and continues to transmit the second signal based on the first PCI during the second SSB occasion. After an end of the transition period, the network node continues to transmit the first signal based on the second PCI during the first SSB occasion, and ceases transmission of the second signal based on the first PCI during the second SSB occasion. Other aspects and features are also claimed and described.
