Abstract: Systems, apparatus, methods, and computer programs for fast, direct SCell activation are disclosed. In one aspect, a method can include receiving, by a UE, an RRC command that causes the UE to be configured to detect a TRS transmission of a plurality of TRS transmission bursts broadcast by an access node, disregarding, by the UE, one or more TRS transmission of the plurality of TRS transmission bursts that are received, by the UE, during processing of the received RRC command, and after processing, by the UE, of the received RRC command, decoding a TRS transmission of the plurality of TRS bursts that is received subsequent to completion of processing of the received RRC command for automatic gain control (AGC).

Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media for beam failure management, and in particular for beam management for high-speed train (HST) in Frequency Range 2 (FR2). According to embodiments of the present disclosure, a terminal device receives from a network device a configuration concerning a high-speed mode of the terminal device, the terminal device determines a reduced evaluation period for beam management in the high-speed mode based on the configuration. The reduced evaluation period determined by the terminal device is shorter than an evaluation period in a non-high-speed mode. Then, the terminal device performs the beam management using the reduced evaluation period.

Abstract: A cell transmits synchronization signal blocks (SSB) to a user equipment (UE) for the UE to synchronize with the cell. The cell configures a discovery reference signal (DRS) window for synchronization signal block (SSB) transmission to a user equipment (UE), determines that a channel in an unlicensed spectrum is not occupied and transmits multiple SSBs to the UE in response to determining that the channel in the unlicensed spectrum is not occupied.
