Abstract: An apparatus is disclosed for implementing multi-mode oscillation circuitry with stepping control. In an example aspect, the multi-mode oscillation circuitry comprises a resonator coupled to a first oscillator and a second oscillator. The multi-mode oscillation circuitry is configured to selectively be in a first configuration with the first oscillator in an active state and the second oscillator in an inactive state or a second configuration with the first oscillator in the inactive state and the second oscillator in the active state. The apparatus also includes a step-control circuit coupled to the multi-mode oscillation circuitry.

Abstract: Techniques are described for video encoding and decoding with same picture or count numbering for scalability support. One example involves obtaining a portion of a picture (e.g., a slice, a block, or other portion) and determining if weighted prediction is enabled for the portion of the picture. When weighted prediction is enabled, a zero value picture order count offset indicating a reference picture from a reference picture can be used, though different portion of the picture (e.g., different slices of a picture) can have different picture order count offset values. The portion of the picture can then be reconstructed using the reference picture identified by the zero value picture order count offset. Additional embodiments can use weighted prediction flags and different offset value determinations to support scalability or reference pictures in weighted prediction with a different size than the picture being reconstructed.

The UE determines whether the downlink transmission is associated with one rate matching or is associated with a separate rate matching for each of the multiple TCI states. The UE derate matches the downlink transmission based on the determination.

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.

Abstract: In an embodiment, a UE receives a first uplink grant for a first RAT (e.g., 5G NR) and a second uplink grant for a second RAT (e.g., LTE). In one embodiment, the UE schedules an uplink transmission on the first RAT (e.g., by selectively dropping the uplink transmission on particular resource blocks) so as to manage an amount of time that is based on concurrent uplink transmissions on both the first and second RATs are performed. In another embodiment, the UE establishes a first period of time where a BSR transmitted by the UE on the first RAT is adjusted based on scheduling of concurrent uplink multi-RAT transmissions, and a second period of time where no BSR is transmitted by the UE on the first RAT based where concurrent uplink transmissions on both the first and second RATs are not permitted to be scheduled.
