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.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may indicate measurement gap information to a base station. For example, a UE may receive signaling configuring hopping patterns for multiple bandwidth parts (BWPs). Each BWP may include resource blocks having a bandwidth that is less than a threshold bandwidth support by the UE. The UE may transmit control signaling indicating measurement gap information for frequency spectrum bands, and the control signaling may indicate whether a measurement gap is applicable for measurements. The indication may be based on hopping patterns and a frequency-domain location of signals to be measured. The UE may determine a measurement gap pattern for an active BWP based on an association between the measurement gap pattern and the active BWP, or between the measurement gap pattern and a hopping pattern. The UE may perform measurements on signals based on the measurement gap pattern.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication that the UE is to perform radio resource management (RRM) measurements at a first periodicity. The UE may identify an RRM measurement relaxation grouping to which the UE belongs based on at least one of a mobility of the UE or a location of the UE within a cell, such as whether the UE is near a cell-edge, or whether the UE is stationary or moving in accordance with low-mobility, or a combination thereof. The UE may determine a first relaxation parameter from a plurality of relaxation parameters based on measurement relaxation criterion associated with the cell, where the plurality of relaxation parameters may be associated with the RRM measurement relaxation grouping. The UE may perform the RRM measurements at a second periodicity that is based on the first relaxation parameter.

Abstract: This disclosure provides systems, methods and apparatus for a signaling mechanism associated with activating a secondary cell (SCell) for uplink control information (UCI), including under circumstances in which the SCell is deactivated and belongs to a timing advance group (TAG) lacking a valid timing advance (TA) value. In one aspect, a user equipment (UE) and one or more components of a network entity may employ a signaling mechanism for establishing an SCell as a PUCCH-SCell in scenarios in which the PUCCH-SCell belongs to a secondary TAG (sTAG) lacking a valid TA value. The signaling mechanism may include signaling to directly provide the network entity with beam measurement information associated with one or more SCells of the sTAG or may include singling that the network entity may use to derive the beam measurement information associated with the one or more SCells of the sTAG.

Abstract: Methods, systems, and devices for wireless communications are described. A serving base station or a serving satellite may transmit a timing configuration to the UE based on a reference unit, such as a location at a beam center for a respective satellite, a threshold distance relative to the beam center for the respective satellite, a reference time, or any combination thereof. In some cases, the UE may monitor for one or more SSBs from the neighboring satellites according to the timing configuration and a respective propagation delay between the UE and each of the neighboring satellites. The UE may measure the SSBs according to the measurement gap and measurement window in the timing configuration. In some examples, the UE may perform a cell handover procedure or a cell reselection procedure based on measuring the SSBs.

Abstract: Methods, systems, and devices for wireless communications are described. A network entity may identify a set of cells associated with performing communications with a user equipment (UE). The network entity may transmit, to the UE, a configuration signal indicating one or more sets of reference signal formats, each set of reference signal formats including a mapping of reference signal formats to respective cells of the set of cells. The network entity may transmit, to the UE, a trigger signal indicating an active set of reference signal formats of the one or more sets of reference signal formats, the trigger signal indicative of reference signal transmission from the cells of the set of cells in accordance with the reference signal formats associated with the active set of reference signal formats.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain emission control information that indicates a first emission control configuration associated with a first operating configuration and a second emission control configuration associated with a second operating configuration. The UE may transmit, using the first emission control configuration or the second emission control configuration based at least in part on a UE operating configuration associated with the UE, a communication. Numerous other aspects are described.

Abstract: Aspects present herein relate to methods and devices for wireless communication including an apparatus, e.g., a UE and/or a base station. The apparatus may identify at least one scheduling offset associated with a propagation delay between a base station of a NTN and the UE. The apparatus may also select a first scheduling offset of the at least one scheduling offset associated with the propagation delay between the base station and the UE. Additionally, the apparatus may transmit, to the base station, an uplink transmission based on the first scheduling offset, the uplink transmission being associated with a PUSCH, a PUCCH, or a PRACH.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a source base station, configuration information for a handover, wherein the configuration information indicates, for a target non-terrestrial cell, timing and synchronization parameters including a scheduling timing offset, a round trip time between a reference point and a target base station associated with the target non-terrestrial cell, satellite ephemeris information, an ephemeris validity duration associated with the satellite ephemeris information, common timing advance parameters, and a common timing advance validity duration associated with the common timing advance parameters. The UE may perform the handover with the target base station associated with the target non-terrestrial cell based at least in part on the timing and synchronization parameters for the target non-terrestrial cell. Numerous other aspects are described.

Abstract: Systems, methods, and devices for secondary cell activation using temporary reference signals are provided. In one aspect, a method of wireless communication performed by a user equipment (UE), includes receiving, from a base station (BS) via a first cell, an activation command to activate a second cell different from the first cell, and receiving, from the BS via the second cell during an activation period, a first reference signal different from a synchronization signal block (SSB). The method further includes performing a measurement of the first reference signal, and operating in the second cell based on the measurement. In some aspects, using reference signals different from SSBs may reduce the delay associated with activating the secondary cell.
