摘要： There is provided a method, computer program, and apparatus for causing an apparatus for a first access node to perform: establishing a connection towards a user equipment via a serving cell supported by the first access node; instructing the user equipment to obtain a first timing advance value for a target cell supported by a second access node, wherein the first timing advance value indicates a timing for transmitting uplink transmissions to the target cell; receiving, from the user equipment, an indication that the first timing advance value is or will soon be invalid; and determining whether to instruct the user equipment to obtain a second timing advance value for the target cell in dependence on the received indication, the second timing advance value being obtained later in time than the first timing advance value.

摘要： Systems, methods, apparatuses, and computer program products for configuration and transmission of a channel state information reference signal (CSI-RS). A method may include forwarding, to a network element, synchronization signal block measurements of a target cell along with synchronization signal block indices. The method may also include requesting the network element to provide a channel state information reference signal configuration for a channel state information reference signal index whose source reference signal corresponds to at least one of the synchronization signal block indices. The method may further include receiving the channel state information reference signal configuration from the network element. In addition, the method may include transmitting the channel state information reference signal configuration to a user equipment. Further, the method may include receiving a measurement report on the channel state information reference signal index according to the channel state information reference signal configuration.

摘要： Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of interruption time reduction. The method comprises receiving, at a terminal device and from a centralized network device, a configuration at least indicating that a L1 measurement for cell change is to be reported by the terminal device with an indication of interruption free TA acquisition for a cell associated with the cell change, or per a panel indication of the terminal device; and transmitting, to a distributed network device, a report of the L1 measurement based on the configuration.

摘要： Systems, methods, apparatuses, and computer program products for the acquisition and provision of channel state information for a target cell early in the process of layer one/layer two inter-cell mobility are provided. For example, a method can include a user equipment receiving a first configuration of layer one measurement and reporting together with a second configuration for channel state information measurement and reporting for a candidate cell. The method can also include reporting layer one measurement according to the first configuration. The method can further include performing channel state information measurements according to the second configuration. The method can additionally include reporting the channel state information measurements to a network element to be forwarded to the candidate cell.
