Abstract: A method and apparatus for timing advance (TA) synchronization for uplink (UL) data transmissions are provided. A base station transmits a TA instruction to a UE. The TA instruction indicates one of at least two TA options. The first TA option indicates direct initial grant-free (GF) uplink (UL) data transmissions. The second TA option indicates indirect initial GF UL data transmissions with the UE initiating TA reference signaling for updating a TA parameter of the UE. The UE performs an initial GF UL data transmission to the base station based on the TA instruction.

Abstract: A method is provided for radio link failure (RLF) detection, link failure recovery, beam failure recovery (BFR) and radio link monitoring (RLM), and for interactions between modules for RLF, BFR, RLM and, integration and unification of indications. A device may measure a reference signal received over one or more communication paths of a radio link to generate reference signal measurements, and select, from the one or more communications paths, at least one path for link quality assessment of a radio link operation based on the reference signal measurements and a configured criterion. The device may generate a radio link indication based on an assessed link quality metric or a link recovery operation status associated with the selected at least one path, and send the radio link indication from a physical layer of the device to a upper layer of the device.

Abstract: Embodiments of the present invention provide a spectrum detection method and apparatus, and a base station. According to the method, in the embodiments, a first base station sends spectrum detection information to an auxiliary device, where the spectrum detection information is used to instruct the auxiliary device to detect whether a first spectrum is occupied; then, the first base station receives first spectrum status information sent by the auxiliary device, so that the first base station determines whether the first spectrum in an area in which the auxiliary device is located is occupied. Therefore, it is implemented that the first base station may determine whether user equipment is interfered by another communications system device in a process in which the user equipment uses the first spectrum, so as to implement sharing of a spectrum by the user equipment with the another communications system device.
