Abstract: Certain aspects of the present disclosure provide techniques for synchronization signal block (SSB) transmission in different frequency intervals. A method that may be performed by a user equipment (UE) includes receiving a first SSB from an entity in a non-terrestrial network (NTN) at a first time and frequency location. The method generally includes determining one or more time and frequency locations of one or more other SSBs from the entity in the NTN based on the first time and frequency location. The method generally includes monitoring for the one or more other SSBs at the determined one or more time and frequency locations.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a transmission frequency for an uplink transmission based at least in part on a reference point for the uplink transmission, the reference point being associated with one of: a satellite that provides a cell covering the user equipment, the satellite being associated with a non-terrestrial network, or a gateway associated with the satellite; and transmit the uplink transmission based at least in part on the transmission frequency. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive, from a base station, a scheduling downlink control information (DCI) communication that schedules a physical downlink shared channel (PDSCH) transmission, the scheduling DCI including an indication of a resource allocation for a DCI communication, wherein the resource allocation for the DCI communication includes one or more resources included in a resource allocation for the PDSCH transmission, and receive the PDSCH transmission that includes the DCI communication based at least in part on the indication of the resource allocation for the DCI communication. Numerous other aspects are provided.

Abstract: A scheduling entity can schedule regular or periodic control resources (CORESETs) that are relatively sparse in the time domain compared to dynamic CORESETS. Sparsely scheduled regular CORESETs can reduce the overhead incurred by a user equipment for monitoring the control channels in the CORESETs or search spaces. When the network has a burst of data to send, the scheduling entity can use downlink control information (DCI) piggybacked in physical downlink shared channel (PDSCH) resources to schedule dynamic CORESETs between the regular CORESETs. The dynamic CORESETs can provide resources for a PDSCH and/or physical downlink shared channel (PUSCH).

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for determining quasi co-location (QCL) and/or transmission configuration information (TCI) state assumption information for a dynamic control resource set (CORESET). In some cases, if certain conditions are met, a user equipment (UE) may follow QCL assumptions for a physical downlink shared channel (PDSCH) scheduled by a same PDCCH that indicated the dynamic CORESET. An example method by a UE generally includes receiving at least one downlink control information (DCI), of a first physical downlink control channel (PDCCH), that schedules at least one dynamic CORESET; and receiving a second PDCCH in the dynamic CORESET, wherein the UE is to apply at least one QCL assumption associated with a PDSCH for the at least one dynamic CORESET if one or more conditions are met.

Abstract: A non-terrestrial network is provided that includes a satellite that transmits an orbital parameter message to a user equipment. The user equipment processes the orbital parameter message to determine a current range from the user equipment to the satellite based upon the received orbital parameter message, a timing offset and a frequency offset for an uplink transmission to the satellite.
