Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a message from a first non-terrestrial network cell indicating cell synchronization information for a second non-terrestrial network cell. In some examples, the cell synchronization information may indicate whether the first non-terrestrial network cell and the second non-terrestrial network cell are synchronized at a reference point. Additionally, or alternatively, the cell synchronization information may indicate a timing offset value between a first uplink time synchronization reference point of the first non-terrestrial network cell and a second uplink time synchronization reference point of the second non-terrestrial network cell. The UE may calculate a timing associated with signaling from the second non-terrestrial network cell based at least in part on the cell synchronization information. The UE may receive one or more signals from the second non-terrestrial network cell based at least in part on the calculated timing.

Abstract: Aspects of the disclosure relate to devices and methods for managing carrier aggregation. Downlink control information (DCI), transmitted via a primary cell (PCell), may include one or more secondary cell (SCell) dormancy indication (SDI) value(s) for one or more secondary cells (SCells). That DCI may also schedule a physical downlink shared channel. A scheduled entity may transmit acknowledgment information indicating whether the scheduled entity successfully received the DCI. Where the SDI indicates a switch in behavior relative to one or more SCell(s) and the acknowledgment information indicates that the scheduled entity successfully received that DCI, the one or more SCell(s) transition from dormant to active or vice-versa. Accordingly, the scheduled entity conforms its behavior to provide the appropriate dormancy and non-dormancy behavior when utilizing, in addition to the PCell, one or more SCell(s) for wireless communication in carrier aggregation.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a first cell. The UE may receive a request to report one or more parameters associated with handover from the first cell to a second cell during a time period. The one or more parameters may include an estimated propagation delay between the UE and the second cell during the time period, an estimated rate of change in propagation delay during the time period, or both. The UE may transmit a message indicating the parameters in response to the request. The UE may receive an indication of an uplink grant occasion associated with the handover during the time period based on indicating the parameters.

Abstract: Certain aspects of the present disclosure provide techniques for enhancing ephemeris for non-terrestrial networks. For example, UEs of different orbit propagation capabilities (e.g., computing orbit propagation models of different accuracy levels) may receive additional ephemeris parameters. In one aspect, a network entity may determine at least one additional set of ephemeris parameters that includes different ephemeris parameters than one or more basic sets of ephemeris parameters associated with a satellite that provides a coverage for the network entity. The network entity may transmit broadcast signaling indicating the at least one additional set of ephemeris parameters. The UE may receive and use the at least one additional set of ephemeris parameters in an orbit propagation model to compute a state of motion of the satellite.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for measurement without gaps for narrow bandwidth part (BWP) hopping. A user equipment (UE) may measure one or more synchronization signal blocks (SSBs) while performing BWP hopping according to a hopping pattern. The UE may receive data and measure an SSB in a same frequency hop during a same measurement window without a gap. A base station (BS) may transmit a control message to the UE to configure an active BWP for the UE, a set of measurement windows, a hopping pattern, and a set of SSBs that occur within a set of frequency hops to support the measurement without gaps. The active BWP may be defined for measurement purposes to reduce ambiguity. The control message may support alignment of a measurement window with an active frequency hop to support measurement without gaps.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a bandwidth part (BWP) hopping configuration indicating a set of hops for a BWP of the UE. The UE may identify a radio link failure (RLF) during a time period configured by the set of hops. The UE may disable the BWP hopping configuration based at least in part on identifying the RLF. The UE may initiate a random access procedure on a BWP that is associated with the random access procedure. Numerous other aspects are described.

Abstract: Aspects described herein relate to communicating with a base station over multiple frequency bands using a first beam, and switching from the first beam to the second beam during a time period or based on a timing of the reference band. Other aspects relate to transmitting an indication of one or more parameters for determining a reference band of the multiple frequency bands to use as a timing reference for switching beams for communicating over the multiple frequency bands.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to reference signal (RS) designs that allow for tracking loop updates and paging of UEs using various RSs. One example method includes identifying reference signal (RS) monitoring occasions for a user equipment (UE) in an idle or inactive mode; and transmitting, to the UE, reference signals in the identified RS monitoring occasions, the RS monitoring occasions being associated with RS for tracking purposes and RS for an indication the UE is to wake up to process additional signaling.
