Abstract: Methods, systems, and devices for wireless communications are described. a first donor node may serve a relay node, which in turn may serve a child node. The first donor node may determine to transfer (e.g., via a handover procedure) the relay node to a second donor node. The first donor node may transmit a first context transfer request for the relay node to the second donor node, and may transmit a second context transfer request for the child node of the relay node to the second donor node. The first donor node may indicate a correlation between the two context transfers. The second donor node may identify the correlated context transfers, and may successfully perform a migration procedure for the relay node and any descendent devices or nodes based on the correlated context transfers.

Abstract: Systems and methods are provided herein for handling Quality of Service (QoS) mobility and dual connectivity. In some embodiments, a method of operation of a network node in a cellular communications network includes deciding to split an existing Protocol Data Unit (PDU) session that includes a current uplink tunnel information; and setting up resources for the split PDU session. In this way, it may be possible to support QoS mobility in the different tunnel during dual connectivity. In some embodiments, the network node is a Master Next Generation—Radio Access Network (NG-RAN) node, and setting up resources for the split PDU session includes sending an S-Node Addition/Modification Request including the current uplink tunnel information for the split PDU session to a Secondary NG-RAN node in the cellular communications network; and receiving a newly added additional downlink tunnel information from the Secondary NG-RAN node.

Abstract: This technology allows time synchronization in wireless networks with mobile stations. A wireless network controller transmits instructions to access points (“APs”) within the wireless network to monitor transmissions for time synchronization. One or more second APs observe fine time measurement (“FTM”) exchanges between a first AP and a mobile station. A particular second AP determines whether to perform a time synchronization with the first AP based on the detection of the FTM exchange or a determination that the station is moving toward the second AP. For time synchronization, the second AP determines the time that the first AP transmitted the FTM exchange and the time of transmission from the first AP to the second AP. The second AP synchronizes a second AP clock to the summation of the time of the transmission of the FTM exchange and the time of transmission from the first AP to the second AP.

Abstract: An indication to schedule a first uplink channel can be transmitted, where the first uplink channel can correspond to a first transmission occasion and a first priority. An indication to schedule a second uplink channel can be transmitted, where the second uplink channel can correspond to a second transmission occasion and a second priority, where the first transmission occasion can overlap in time with the second transmission occasion and the first priority can be higher than the second priority. A particular symbol of the second uplink channel from which a transmission of the second uplink channel is cancelled by a user equipment can be determined based on the first transmission occasion overlapping in time with the second transmission occasion. A reception of the second uplink channel can be cancelled based on the determined particular symbol.

Abstract: Timing advance (TA) handling for sidelink (SL)-assisted positioning of a first user equipment (UE), comprises determining the first UE is configured to transmit an SL positioning reference signal (SL-PRS) to a second UE for the SL-assisted positioning. A guard period length can be determined based on a configuration of the first UE for transmitting the SL-PRS, where the guard period may comprise a period of time during which the SL-PRS is transmitted by the first UE. A message can be sent to a serving transmission reception point (TRP) of the first UE, where the message indicates the guard period and comprises a TA-related request. The TA-related request includes a request to postpone applying a TA command received by the first UE until after the guard period, or a request for the serving TRP not to send a TA command to the first UE during the guard period.

Abstract: Adaptive energy detection (ED) threshold medium access is discussed based on deployment and traffic type. The network nodes sharing a shared communication network are configured with multiple discrete ED thresholds or a range of ED values. As a transmitting node prepares to attempt access to the shared communication spectrum, it identifies an access trigger condition within the network. Such a condition may include traffic type, deployment, or access conditions. In response to detecting an access trigger condition, the transmitting node may select an ED threshold associated with the access trigger condition. Alternatively, upon detection of the access trigger condition, the transmitting node may implement a random ED threshold from the candidate range of ED threshold values.

Other aspects relate to transmitting the TA command and not receiving an overlapping uplink transmission.
