Abstract: A method of wireless communication by a receiving device includes receiving a message by the receiving device from a transmitting device. The method further includes identifying a type of the message based on a message header of the message. The message header includes an identifier field of a determined length. The identifier field includes an identifier associated with the type of the message. The identifier is selected from a set of identifier values including one or more identifier values that fully identify the type of the message and one or more extension field inclusion values that indicate an inclusion of an extension field of the identifier field.

Abstract: This disclosure provides systems, methods and apparatuses, including computer programs encoded on computer storage media, for uplink switching for enhanced mobility. In some aspects, this disclosure provides techniques for potentially reducing or eliminating service interruptions experienced during a handover from a source cell to a target cell. Additionally, this disclosure provides techniques for potentially simplifying or improving uplink communications while a UE is connected to both the source cell and the target cell during the handover. This disclosure further provides techniques for potentially reducing UE power consumption or improving uplink resource utilization during a handover from a source cell to a target cell while a UE is connected to both the source cell and the target cell during the handover.

Abstract: A method and apparatus for receiving a notification of missing packets include receiving a set of data packets transmitted by a device and having a corresponding set of sequence numbers, identifying one or more data packets having corresponding sequence numbers that fall within the set of sequence numbers and are yet to be received, receiving an indication from the device that the one or more data packets will not be transmitted by the device, and processing the set of data packets without the one or more data packets in response to receiving the indication.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment concurrently communicates with a source base station (BS) and a target BS on a connection with the source BS and a connection with the target BS as part of a make-before-break (MBB) handover procedure; and performs a common packet data convergence protocol (PDCP) function for the connection with the source BS and the connection with the target BS before the connection with the source BS is released as part of the MBB handover procedure. Numerous other aspects are provided.

Abstract: In an aspect, a network supporting a number of client devices includes a network device that generates a context for a client device. The client device context may include network state information for the client device that enables the network to communicate with the client device. The client device may obtain, from a network device that serves a first service area of the network, information that includes a first client device context. The client device may enter a second service area of the network served by a second network device. Instead of performing a service area update procedure with the network, the client device may transmit a packet in the different service area with the information that includes the client device context. The client device may receive a service relocation message including information associated with the different network device in response to the transmission.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may select at least one target node for a radio resource control connection, wherein the user equipment is in a particular radio resource control communication state when the at least one target node is selected, and wherein the user equipment is configured to communicate using dual-connectivity, wherein context information associated with the user equipment is stored by the user equipment, a master node associated with the user equipment, and a secondary node associated with the user equipment based at least in part on the user equipment being in the particular radio resource control communication state; and/or transmit information to the at least one target node or the master node to cause the context information to be provided to the at least one target node. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide methods and apparatus for beam selection in uplink-based and downlink-based mobility scenarios, for example, for new radio (NR) systems which can improve handover reliability, reduce handover frequency, and improve power efficiency. Certain aspects provide a method for wireless communications by a user equipment (UE). The method generally includes transmitting an uplink reference signal with an indication of a preferred downlink beam and receiving a downlink transmission based, at least in part, on the uplink reference signal.

Abstract: A method, an apparatus, and a processor-readable storage medium for wireless communication are provided. A transmitter transmits data packets to a receiver, encodes the data packets to generate parity packets, stores the parity packets in a retransmission buffer, receives information from the receiver indicating that a data packet was not correctly decoded, and transmits to the receiver the parity packets stored in the retransmission buffer for recovering the data packet not correctly decoded without retransmitting the data packet not correctly decoded. The transmitter may further retransmit to the receiver the parity packets. The transmitted data packets may be encoded at a medium access control (MAC) layer of the transmitter. The retransmission buffer may be located at a radio link control (RLC) layer or a packet data convergence protocol (PDCP) layer of the transmitter. A reordering buffer at the receiver may be located at the RLC layer or PDCP layer.

Abstract: Various aspects of the disclosure relate to delivering a limited amount of system information. For example, the delivery of system information may be divided into broadcasting a limited amount of the system information and using unicast signaling for delivery of the remaining system information. In some aspects, the delivery of a limited amount of system information may involve broadcasting a compressed PLMN ID list (e.g., broadcasting indications of PLMNs). In some aspects, the delivery of a limited amount of system information may involve broadcasting an indication of the version of system information that is valid for a cell. In some aspects, the delivery of a limited amount of system information may involve broadcasting multiple configurations of system information along with indications of each configuration. In some aspects, the delivery of a limited amount of system information may involve broadcasting compressed non-cell-related system information.

Abstract: In an aspect, a network supporting client devices includes one or more network nodes implementing network functions. Such network functions enable a client device to apply a security context to communications with the network when the client device is not in a connected mode. The client device obtains a user plane key shared with a user plane network function implemented at a first network node and/or a control plane key shared with a control plane network function implemented at a second network node. The client device protects a data packet with the user plane key or a control packet with the control plane key. The data packet includes first destination information indicating the first network node and the control packet includes second destination information indicating the second network node. The client device transmits the data packet or control packet.
