One method may include a UE determining that a first TCI state is to be applied in a first slot and a second TCI state is to be applied in a second slot. The first TCI state is associated with a first TAG ID, a second TCI state is associated with a second TAG ID different than the first TAG ID, and the second slot is succeeding and adjacent to the first slot. The method may further include, based upon the determining, determining a third slot. The second TCI state is firstly to be applied in the third slot.

Abstract: Embodiments of the present disclosure relate to timing adjustment. A terminal device performs timing advance (TA) acquisition on at least one target cell for cell switching from a serving cell for the terminal device to one of the at least one target cell. Then, the terminal device adjusts downlink timing of the at least one target cell, when a timer is running at the terminal device. As a result, it is allowed to efficiently control downlink timing maintenance burden at the terminal device.

Abstract: Embodiments of the present disclosure relate to methods, devices, apparatuses, and computer readable medium for positioning enhancement mechanism. A first device determines that a third device is to transmit a positioning related message in a non-connected state. The first device transmits assistance information to a second device serving the third device. The assistance information comprises at least one of data size and a transmission periodicity for the positioning related message. By means of the assistance information, the base stations are provided with proactive knowledge of the positioning related message. In this way, the base station is capable of determining appropriate configurations for the SDT procedure. The terminal device may then transmit the positioning related message in the RRC NON-CONNECTED state via the SDT. As such, the efficiency of SDT procedure can be improved, while avoiding segmentation or subsequent transmission of the positioning report.
