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.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a first base station for wireless communication, associated with a first radio access technology (RAT), may generate a message to cause a user equipment to wake up from a power saving state or to reconfigure a cycle associated with the power saving state, wherein the message includes an indication that the user equipment is to wake up from the power saving state or to reconfigure the cycle; and/or transmit the message toward the user equipment via a second base station, associated with a second RAT and the user equipment, to cause the user equipment to wake up from the power saving state or reconfigure the cycle. Numerous other aspects are provided.

Abstract: Systems and methods for enabling and providing uplink based mobility procedures are disclosed. Embodiments provide uplink based mobility procedures in which one or more physical channel typically used to facilitate uplink based mobility is not utilized. For example, an uplink based mobility process of embodiments utilizes a UL-based mobility specific ID and/or synchronization signals to provide information for decoding signals avoiding the use of physical cell identifier channel (PCICH). Embodiments of an uplink based mobility process utilize a physical channel, such as a physical slot format indication channel (PSFICH) or a physical downlink control channel (PDCCH), to provide uplink mobility signal acknowledgements and paging indications avoiding the use of a physical keep alive channel (PKACH).

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: Discovery and synchronization channels are discussed for user-tracking zones in a cellular network. User-tracking zones reduce the mobility tracking burden on the UE and shift the tracking responsibility to the network. This shift allows for UE and network power savings from reduced searching at the UE as well as through efficient paging area tracking and less broadcast signaling. The various aspects provide channel design for initial synchronization and discovery of the user-tracking zones. A single frequency network (SFN) synchronization channel is provided with at least a reference signal for time synchronization and payload information that may include a zone identifier (ID), formatting for a system information transmission request, and resource allocation for the request. The zone ID may be included in the payload or embedded into the reference signal. Facility is also provided for handling zone nodes of different power classes that allows for maintaining the SFN operations.
