Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may establish a packet data network (PDN)-connectivity session to a PDN using a cellular radio access technology (RAT) and migrate the PDN-connectivity session from a source access node (AN) to a target AN. Migration may initiate when a decision to perform a handover is made. The target AN may receive a network address and information about a first data radio link established between the UE and source AN. The target AN may establish a second data radio link with the UE based at least in part on the first data radio link information, and may transmit, to the PDN, a path update including the network address and an updated path via the target AN. In some cases, the target AN may forward packets between the UE and the PDN via the second data radio link.

Abstract: A network management function of a relay network may identify relay node support of multi-mobile terminal (MT) operation, and may coordinate configuration of multiple backhaul links supported by the relay node via the multi-MT functionality of the relay node. In some cases, a relay node may transmit MT capabilities to the management function over a first established backhaul link, and the management function may configure a second backhaul link using a second MT function of the relay node. In other cases, the relay node may autonomously establish multi-MT connectivity based on preconfigured parent-selection policies, and the network management function may identify the relay node is dual-connected to the network management function. In either case, the network management function may configure backhaul routes (e.g., backhaul links) and resource configuration across the redundant topology.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE), may receive, at a processing layer of the UE, sets of discontinuous reception (DRX) cycle parameters from a corresponding set of applications at an application layer of the UE. The UE may determine, based on the sets of DRX parameters, a common DRX cycle to satisfy each of the sets of applications. The UE may transmit the common DRX cycle to one or more layers in the user plane protocol stack of the UE. A base station may also receive a request, from the UE, for a set of DRX cycle parameters that satisfies the common DRX cycle of the UE. The base station may transmit an indication of the set of DRX parameters, and receive, from the UE, a confirmation of a DRX cycle associated with the set of DRX cycle parameters.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless systems, a base station centralized unit (CU) may communicate with a user equipment (UE) through a multi-hop backhaul architecture. This multi-hop backhaul connection may include a donor base station and any number of relay base stations connected via backhaul links. In some cases, the relay base stations or the UE may experience data congestion in a logical channel-specific buffer. The relay base stations or UE may implement backpressure signaling (e.g., in the medium access control (MAC) layer) to mitigate the congestion. A wireless device operating as a mobile termination (MT) endpoint may transmit a backpressure report message to a wireless device operating as a base station distributed unit (DU) endpoint for the logical channel. The base station DU may adjust a scheduling rate for data unit transmissions over the indicated logical channel based on the backpressure report.

Abstract: Methods and apparatus for configuring a UE to assist in mitigating network congestion include determining whether a data packet has expired based on a first parameter, which indicates an expiration of the data, and adjusting a transmission of the data packet based on the determination of whether the data packet has expired. In some aspects, the UE may drop the data packet upon determination that the data packet has expired. The UE may be configured detect to a first congestion level, receive a second congestion level from a second UE, and process a frame for transmission based on the first or second congestion level. The UE may be configured determine a priority, generate a data packet that includes a destination parameter or a source parameter, adjust radio resource parameters based on the destination parameter or source parameter, and transmit data packets according to adjusted radio resources.

Abstract: Methods, systems, and devices for wireless communications are described, in which a user equipment (UE) may communicate with one or more other UEs using sidelink communications. Multiple UEs may form a sidelink communications group and provide for sidelink groupcast communications in which an identification of a UE is determined based at least in part on a member identification of the UE within the group. Each UE in the group may determine feedback resources for acknowledgment feedback within the group based on a UE identification and a size of the group.

Abstract: A relay node at a base station may configure a first radio channel with a first priority and a first priority ID, and configure a second radio channel with a second priority and a second priority ID. The base station may configure a third radio channel with a first bearer ID and a first mapping to the first priority, and configure a fourth radio channel with a second bearer ID and a second mapping to the second priority. The relay node may forward packets from the third radio channel to the first radio channel based on the first mapping and insert the first priority ID into a header in the packets. The relay node may forward packets from the fourth radio channel to the second radio channel based on the second mapping, and insert the second priority ID into a header in the packets.

Abstract: A method, apparatus, and computer-readable medium for transmission control include receiving, at a non-access stratum protocol layer, a packet including a reliability request from an application, and determining if the application is authorized to make the reliability request. Further, the aspects include, in response to determining the application is authorized to make the reliability request, performing one of: sending the packet including the reliability request to an access stratum protocol layer, or sending the packet with a modified reliability request to the second protocol layer. Additionally, the aspects include transmitting the packet. Further aspects describe a control plane delivery mechanism for provisioning UE, such as with policies and/or configurations including transmission control reliability authorization information.

Abstract: Methods, systems, and devices for wireless communications are described. The method, system, and apparatus may include managing the operation mode of a user equipment in vehicle-to-everything communication. In some aspects, a user equipment may transmit an inactive request message (or a request message) to a base station to indicate the user equipment is switching from a base station scheduling mode (or a radio access network node scheduling mode) to a peer user equipment scheduling mode (or a roadside unit scheduling mode). The user equipment may receive an acknowledgment message from the base station indicating a state change to allow the peer user equipment scheduling mode. In some cases, the user equipment may receive an area identifier from the base station, and the area identifier may indicate an area where the peer user equipment scheduling mode is allowed.
