Abstract: Methods, systems, and devices for wireless communications are described. For instance, a user equipment (UE) may receive, from a base station, a first downlink control information message in a downlink control channel, the first downlink control information message scheduling first resources of a downlink shared channel for a second downlink control information message. The UE may identify a first, UE-specific scrambling sequence for the second downlink control information message. The UE may receive, from the base station, the second downlink control information message based on the first scrambling sequence, the second downlink control information message scheduling second resources of the downlink shared channel for a data message. The UE may receive, from the base station, the data message in the second resources scheduled by the second downlink control information message.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a message indicating a time domain window (TDW) configuration including a start time of a TDW and a length of the TDW, where the TDW is a duration over which a network entity is scheduled to perform joint channel estimation. The UE may receive a timing advance (TA) command during the TDW indicating a TA value to apply to signaling. The UE may transmit the signaling in accordance with the TA value or independent of the TA value based on the UE prioritizing the TA adjustment or maintaining power consistency and phase continuity for DMRS bundling, respectively. The UE may determine whether to prioritize the TA adjustment or DMRS bundling for the joint channel estimation based on one or more parameters satisfying criteria.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may identify an energy per resource element (EPRE) ratio between a synchronization signal block (SSB) symbol containing a primary synchronization signal (PSS) and an SSB symbol containing a secondary synchronization signal (SSS), a physical broadcast channel (PBCH), or both, based on an operating band for the UE, a bandwidth of the SSB symbol containing the PSS and the SSB symbol containing the SSB, the PBCH, or both. The EPRE ratio may be based on maximum regulatory equivalent isotropically radiated power (EIRP) limits, maximum regulatory power spectral density (PSD) limits for the band, or both. The EPRE ratios may be different for different SSB symbols, when different SSB symbols have different bandwidths. A base station may configure and transmit, and a UE may receive, the SSB according to the identified EPRE ratio.

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.
