Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive system information associated with a set of neighboring cells included in a non-terrestrial network (NTN). The UE may be connected to or camped in a current cell included in the NTN. The current cell may be associated with a current platform. The UE may monitor a neighboring cell, of the set of neighboring cells, based at least in part on the system information. 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 an indication of a polarization of at least one synchronization signal block (SSB). The UE may determine a polarization of another beam based at least in part on the indicated polarization. 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 determine timing misalignment information for a timing misalignment between an uplink timeline and a downlink timeline associated with a non-terrestrial cell. The UE may transmit the timing misalignment information to a satellite associated with the non-terrestrial cell. Numerous other aspects are described.

Abstract: Aspects described herein relate to communicating a demodulation reference signal (DMRS) corresponding to a downlink control channel, buffering, based on receiving the DMRS, samples of a downlink data channel associated with the downlink control channel, and processing, during on a time period indicated based at least in part on a sequence of the DMRS, at least a portion of the samples of the downlink data channel. Another aspect relates to determining, based at least in part on a sequence of the DMRS, a time offset from the downlink control channel to a downlink data channel, and determining, based at least in part on the time offset, a time period based on which to transmit or start processing samples of the downlink data channel.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for mitigating timing resolution limitations due to synchronization signal blocks (SSBs) with low subcarrier spacing (SCS). An example method by a user equipment (UE) generally includes detecting a SSB; determining a start time of a control resource set (CORESET) associated with the detected SSB, wherein the start time of the CORESET is aligned with a boundary of a symbol having a larger cyclic prefix (CP) than one or more other symbols in a same half-subframe; and monitoring the CORESET for a physical downlink control channel (PDCCH) transmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive configuration information that schedules a search space set; receive, on the search space set, first downlink control information (DCI) that schedules or configures one or more second DCIs that are multiplexed with one or more semi-persistent scheduling occasions; and process the one or more second DCIs based at least in part on the first DCI. Numerous other aspects are provided.

Abstract: Aspects described herein relate to receiving, from a base station, a downlink communication indicating resources scheduled for one or more repetitions of a downlink control channel, receiving, from the base station, the one or more repetitions of the downlink control channel, and combining the one or more repetitions of the downlink control channel to decode the downlink control channel. In another aspect, the network can transmit, to a user equipment (UE), a downlink communication indicating resources scheduled for one or more repetitions of a downlink control channel, and transmitting, to the UE, the one or more repetitions of the downlink control channel over the resources.

Abstract: Aspects of the present disclosure relate to a technique for determining quasi co-location (QCL) and/or transmission configuration information (TCI) state assumption information for a dynamic control resource set (CORESET). A user equipment (UE) may receive and/or detect a downlink control information (DCI) that schedules at least one dynamic CORESET and indicates a TCI state from a list of one or more TCI states for the dynamic CORESET. The UE may apply the indicated TCI state for processing physical downlink control channel (PDCCH) transmissions in the dynamic CORESET when one or more conditions are met.
