Abstract: A user equipment (UE) may receive, from a base station (BS) configured to support activation of a secondary cell (SCell), a request to provide a measurement report. In response to the request, the UE may perform one or more measurements on the SCell using one or more reference signals (RSs). Additionally or alternatively, the UE may generate the measurement report based on the one or more measurements and further transmit the measurement report to the BS. In some embodiments, the UE may further determine a pathloss estimation based on the one or more measurements.

Abstract: Systems and methods provide multiple cell activation. A user equipment (UE) receives, from a wireless network, a command to activate multiple cells simultaneously. In response, the UE initiates cell activation procedures for the multiple cells. The cell activation procedures include waiting for an active transmission configuration indicator (TCI) indication. The UE monitors for the active TCI indication on any of the multiple cells. In response to receiving the active TCI indication on a first cell of the multiple cells, the UE determines one or more second cells of the multiple cells that share a same spatial relationship with the first cell according to one or more predetermined rule, and autonomously continues the cell activation procedures for the first cell and the one or more second cells.

Abstract: A user equipment (UE) configures radio resource management (RRM) relaxation in extended discontinuous reception (eDRX) in cases with or without a paging transmission window (PTW). The UE determines whether an eDRX cycle is configured as being greater or less than 10.24 seconds; determine whether the UE has met legacy RRM relaxation criteria for a relaxation scaling factor k; and configures RRM relaxation timing based on use of a paging transmission window (PTW) and the relaxation scaling factor k.

Abstract: Disclosed are methods, systems, and computer-readable medium to perform operations including: determining time or frequency synchronization information for each of one or more candidate synchronization signal blocks (SSBs) for a secondary cell (SCell) before receipt of a transmission configuration indication (TCI) state activation command or a SCell activation command, receiving the TCI state activation command, and based on the received TCI state activation command, receiving at least one signal from the SCell using the determined time or frequency synchronization information for one of the one or more candidate SSBs.
