Abstract: Mechanisms are provided for a user equipment (UE) to perform a handover operation from a first base station in a serving cell to a second base station in a target cell under conditions. The UE can receive a conditional handover instruction including a channel quality condition for the handover operation and an additional condition for the handover operation. The UE may determine an operation order between testing the channel quality condition and testing the additional condition, and further determine whether the channel quality condition or the additional condition is met or not. In response to a determination that the channel quality condition is met and a determination that the additional condition is met, the UE can perform the handover operation to handover the UE from the first base station to the second base station.

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: Some aspects relate to apparatuses and methods for implementing mechanisms for a network to trigger the UE to obtain synchronization with one or more cell neighbors in the network. Some aspects of this disclosure relate to apparatuses and methods for implementing mechanisms for measuring and using TA for a beam group and for uplink signal multiplexing. For example, a UE includes a transceiver configured to wirelessly communicate with a serving cell and a processor communicatively coupled to the transceiver. The processor receives, from the serving cell, a first message indicating Physical Random Access Channel (PRACH) resource configuration associated with a neighbor cell. The processor further receives a second message to trigger transmission of a PRACH message to the neighbor cell. The processor further generates the PRACH message responsive to the second message and according to the PRACH resource configuration cell and transmits the PRACH message to the neighbor cell.
