Abstract: The exemplary embodiments relate to a user equipment configured to connect to a network that supports simultaneous connection to a first radio access technology (RAT) and a second RAT. The UE may receive coverage information associated with the first RAT and a cell of the second RAT, receive an indication of the current UE location relative to the cell of the second RAT and determine whether the first RAT is available for camping based on the coverage information and the indication of the current UE location relative to the cell of the second RAT.

Abstract: A user equipment device may determine whether to power down one or more components based at least on a scheduling parameter that includes an indication of cross-slot scheduling. The device may power down the one or more components prior to decoding control information during a slot for which the scheduling parameter indicates that cross-slot scheduling is in place.

Abstract: Techniques described herein may enable a user equipment (UE) to optimize radio access technology (RAT) and radio resources (e.g., bandwidth parts (BWPs)) when communicating with the network. This may be based on one or more factors or conditions, such as whether the UE is currently using 4th generation (4G) RAT or 5th generation (5G) RAT, whether the UE is in an active mode or idle mode, a BWP used by the UE, whether an application or network service requires a certain throughput, a type of application being used by the UE, an amount of network congestion, and so on. RAT optimization may also be based on whether the UE is using a frequency range 1 (FR1) or frequency range 2 (FR2), whether the UE is stationary or moving, whether the UE is experiencing beam failures, uplink (UL) switches, link quality measurements (LQMs), reference signal received power (RSRP) measurements, and so on.

Abstract: This disclosure relates to techniques for reducing latency in a high-propagation-delay wireless communication system. A user equipment device (UE) may transmit to a base station a random access initiation message, having a characteristic that is configured to indicate to the base station a requested size of a subsequent uplink grant to be provided by the base station for transmission of uplink data by the UE. For example, the characteristic may include a predetermined preamble included in the random access initiation message, such that a requested grant size is indicated by which preamble the UE selects from a plurality of possible preambles. As another example, the characteristic may include which RACH occasion is selected by the UE to transmit the random access initiation message. In response, the base station may allocate resources for use by the UE based on the characteristic.

Abstract: A user equipment (UE) device may perform random access to a base station in the context where propagation delay between the base station and the UE device is large. The UE device randomly selects a random access preamble from an available set of preambles. The UE device selects a time slot for transmission of the random access preamble based on a configured correspondence between allowable time slots and subsets of the available set. The UE device transmits the random access preamble to a base station in the selected time slot, with timing advance to compensate for a common delay. Thus, the base station, knowing the configured correspondence, is able to determine the time slot in which the random access preamble was transmitted. The UE device receives a random access response that has been addressed with a Random Access Radio Network Temporary Identifier (RA-RNTI).

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment (UE) device to adaptively provide enhanced the quality of service (QoS) for an application. The UE may request a dedicated bearer or flow for communications conducted over a network between a UE application and a server associated with the application. The UE may use various information, including a QoS profile associated with the application, to determine requested QoS parameters and/or determine whether to provide the enhanced QoS functionality, e.g., whether to request the dedicated bearer/flow from the network. These techniques may tend to provide more appropriate QoS to the application, which may improve user experience.
