Abstract: Wireless communications systems and methods related to signaling of direct current (DC) locations of user equipment devices (UEs) in a new radio (NR) network are provided. A wireless communication device receives, from a base station, at least one of a carrier aggregation (CA) configuration or a bandwidth part (BWP) configuration. The wireless communication device determines a direct current (DC) location based on at least one of the CA configuration or the BWP configuration. The wireless communication device transmits, to the base station, a report based on the determined DC location. The wireless communication device communicates, with the base station, a phase tracking reference signal (PTRS) configured based on the report.

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: Systems and techniques are disclosed to separate paging and access cell selection (and use) among available cells based on different paging cell and access cell requirements and specific service availability. A UE selects a first cell that meets paging cell requirements as a paging cell and a second cell that meets service requirements as an access cell. Once the UE selects a paging cell, the UE camps on the paging cell to wait for a paging request or a mobile originated request. The UE can select and camp on the access cell prior to a data need, where latency requirements are strict, or delay access cell selection until there is data to transmit where latency requirements are more lax. The UE may also include measurement information of surrounding cells with a paging response/service request, which a core network uses to speed up establishment of dual connectivity or carrier aggregation.

Abstract: Techniques are described for wireless communication. A method for wireless communication at a user equipment (UE) includes establishing a connection with a network node; receiving from the network node, as part of establishing the connection, an AS security indication indicating an AS protocol layer for protecting data packets; and configuring AS security protection for data packets based at least in part on the AS security indication and the indicated AS protocol layer. A method for configuring AS security includes establishing a connection with a UE; receiving from a network access device controller, as part of establishing the connection, an AS security indication indicating an AS protocol layer for protecting data packets; and configuring AS security protection for data packets transmitted to or received from the UE based at least in part on the AS security indication and the indicated AS protocol layer.

Abstract: Various aspects described herein relate to techniques for mobility mode selection in uplink-based and downlink-based mobility in wireless communications systems. In an aspect, a method for wireless communications may include determining that a user equipment (UE) is operating in a first mobility mode, determining whether the UE satisfies at least one condition associated with mobility of the UE for mobility mode selection, and selecting a second mobility mode based on a determination that the UE satisfies the at least one condition, wherein each of the first mobility mode and the second mobility mode is an uplink mobility mode or a downlink mobility mode. The techniques described herein may apply to different communications technologies, including the 5th Generation (5G) New Radio (NR) communications technology.

Abstract: Methods, systems, and devices for wireless communication are described. The methods, systems, and devices may provide for a time varying allocation of resources which includes a shared pattern of resources. The shared pattern of resources may be generated, determined, or otherwise identified by a base station and transmitted to the user equipment (UE). The shared pattern of resources may include one or more resource blocks (RBs) allocated for uplink transmission such as uplink control information to be transmitted using a physical uplink control channel (PUCCH) or uplink data transmissions using a physical uplink shared channel (PUSCH).

Abstract: Methods, systems, and devices are described for wireless communication. A first method includes receiving, at a user equipment (UE), a first set of system information; determining, based at least in part on the first set of system information, that additional system information is available; transmitting a request for the additional system information; and receiving the additional system information at the UE. A second method includes transmitting, from a base station, a first set of system information; receiving a request for additional system information; and transmitting the additional system information based at least in part on the request.

Some aspects provide for assembling a first frame comprising one or more packets, transmitting the first frame, determining whether a portion of one or more packets was truncated during the assembling of the first frame, and transmitting a second frame comprising at least the truncated portion of the one or more packets of the first frame. Some aspects provide for receiving a first frame comprising one or more packets, determining that a portion of one or more packets is truncated, and determining whether to ignore as padding at least the truncated portion of the one or more packets of the first frame.

Abstract: A method, an apparatus, and a processor-readable storage medium for wireless communication are provided. In an aspect, the apparatus is a subordinate entity that receives an indication of a resource allocated for an uplink transmission. The subordinate entity also receives a condition associated with the resource. The subordinate entity evaluates whether the condition is satisfied and determines whether to transmit a packet using the resource based on the condition being satisfied. In another aspect, the apparatus is a scheduling entity that generates an indication of a resource allocated for an uplink transmission. The resource is associated with a condition that limits access to the resource. The scheduling entity transmits the indication and the condition to a subordinate entity and receives a packet from the subordinate entity via the resource based on the condition being satisfied.
