Abstract: Aspects of the present disclosure provide systems and methods for informing a user equipment (UE) that which beam the UE is being served, for example, such as in relation to bandwidth part (BWP) switching in a non-terrestrial network (NTN). According to certain aspects, a network entity may transmit to a user equipment (UE) signaling indicating at least one BWP switch. The network entity provides, to the UE, an indication of a serving synchronization signal block (SSB) for the UE to use after the BWP switch.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a non-terrestrial network (NTN) entity, a message that is associated with an uplink grant. The UE may select, based at least in part on the message, either a cell-specific offset or an updated offset that is indicated after initial access, as a timing offset that accounts for a propagation delay between a base station of the NTN and the UE. The UE may transmit, to the NTN entity, an uplink communication using the timing offset. Numerous other aspects are described.

Abstract: A wireless communication network includes a user equipment (UE) to receive a set of instructions, from a base station, to perform a simultaneous change of a set of current bandwidth parts (BWPs) to a set of new BWPs in a set of cells. The set of instructions schedules set of slots for the UE to receive and/or transmit a set of downlink and/or uplink signals via the set of new BWPs, respectively. The UE also determines a delay associated with performing the simultaneous change of the set of current BWPs to the set of new BWPs, respectively, and determines whether it is able to receive and/or transmit the set of downlink and/or uplink signals via the set of new BWPs in the set of slots satisfying the delay, respectively. A base station is also included to communicate with the UE to effectuate the aforementioned operation.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may monitor, using a first physical downlink control channel (PDCCH) monitoring behavior, for a first downlink control information (DCI) format that indicates a set of resources associated with at least one of a cross component carrier (CC) scheduling or a multiple CC scheduling associated with a first CC and a second CC. The UE may monitor, using a second PDCCH monitoring behavior based at least in part on a determination that a PDCCH monitoring behavior switch condition is satisfied, for a second DCI format. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration for a bandwidth part (BWP). The BWP may overlap with one or more first frequency resources associated with a cell-defining synchronization signal block (CD-SSB) and one or more second frequency resources associated with a non-cell-defining synchronization signal block (NCD-SSB). The UE may perform a measurement using the NCD-SSB (and not the CD-SSB) during an active state of the BWP. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive layer-1/2-triggered mobility (LTM)-based configurations of one or more neighbor cells. The UE may transmit an indication of one or more of a set of one or more latencies or a set of interruption information in association with transmitting random access channel (RACH) communications associated with respective configurations of the LTM-based configurations of the one or more neighbor cells. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communications by an apparatus. A method includes sending user equipment (UE) assistance information to a network entity, the UE assistance information comprising information indicative of: a requested length of a requested time window; a requested periodicity at which the requested time window repeats; and a first requested communication configuration for communicating during the requested time window; receiving a communication configuration from the network entity; and communicating according to the communication configuration.

Abstract: Certain aspects of the present disclosure provide techniques for signaling a scheduling offset for non-terrestrial networks (NTNs). In one aspect, a method for wireless communications by a user equipment (UE) includes receiving first signaling indicating a first part of a scheduling offset associated with a common timing advance (TA); receiving second signaling indicating a second part of the scheduling offset; and transmitting an uplink transmission based on the first and second parts of the scheduling offset.

Abstract: Apparatus, methods, and computer program products for wireless communication are provided. An example method may include receiving, from a network entity, a configuration indicative of a transmit power difference between a special cell in a first frequency band and a secondary cell without an SSB in a second frequency band. The example method may further include determining, based on a condition of an absence of a synchronization signal configuration for the secondary cell, a power of a signal associated with the secondary cell based on the transmit power difference and a measured power associated with the special cell. The example method may further include communicating, with the network entity, via the secondary cell and based on the power determined for the signal associated with the secondary cell.

Abstract: Various aspects of the present disclosure generally relate to wireless communication and more particularly to hybrid measurements and reporting for Layer 1 (L1)/Layer 2 (L2) triggered mobility (LTM). Some aspects more specifically relate to a UE performing filtered measurements of one or more LTM candidate cells. In some aspects, the hybrid measurements and reporting may be associated with measurements using Layer 3 type measurements and reporting using L1 type reports for LTM. In some aspects, one or more cells, from the one or more LTM candidate cells, may be selected (for example, by the UE or by a network node) for L1 measurement or reporting associated with the filtered measurement values. In some aspects, the UE may transmit an L1 measurement report indicating L1 measurement values of the one or more cells. A network node may perform one or more operations in response to the L1 measurement values.
