摘要： Embodiments of the present disclosure relate to methods and apparatus for beam maintenance in a radio access network, in particular, through random access preamble transmission for beam maintenance. A terminal device receives, from a network device, a resource configuration for contention-free random access. The resource configuration indicates a plurality of CFRA resources each associated with a respective synchronization signal and physical broadcast channel block index or channel state information reference signal index. The plurality of CFRA resources are applicable for timing advance acquiring in a target network device. The terminal device transmits, to the target network device, one or more CFRA physical random access channels based on the resource configuration. In this way, beam maintenance may be performed based on an SSB index or CSI-RS index associated with one of the transmitted CFRA PRACH(s) before a cell switch command or a random access response.

摘要： Examples of the present disclosure relate to User Equipment positioning. Certain examples provide an apparatus (10), for example such as a RAN node (120) or a Location server (140), configured to: determine Position Reference Signal, PRS, configuration information (605, 705) comprising information for enabling a network element, for example such as a UE (110) or a RAN node (120), of a RAN (100) to: send a PRS (200), wherein the PRS comprises: a first portion (201) of the PRS configured to be sent in a first time interval (T1) over a first frequency range (fr1); a second portion (202) of the PRS configured to be sent in a second time interval (T2), different to the first time interval, over a second frequency range (fr2), wherein the second frequency range partially overlaps the first frequency range thereby defining an overlapping frequency range (ofr); and wherein a subrange of frequencies (ufr) of the second frequency range is not used to send the second portion of the PRS; and send, the PRS configuration information to the network element of the RAN.

摘要： Systems, methods, apparatuses, and computer program products for reporting of feasibility of activated transmission configuration indicator/transmission coordination indication (TCI) states. For example, a user equipment (UE) may determine whether one or more measurements satisfy one or more thresholds for one or more TCI states, and may transmit an indication of whether the one or more measurements satisfy the one or more thresholds. The UE may then deactivate at least one of the one or more activated TCI states, or may activate one or more additional TCI states, based on the indication, and may use one or more of the activated TCI states for a downlink (DL) or uplink (UL) transmission.
