Abstract: Systems, methods, apparatuses, and computer program products for user equipment based timing advance measurements. The method may include receiving a layer 1/layer 2 triggered mobility configuration for one or more candidate target cells, wherein UE-based TA measurement is enabled for a plurality of cells comprising the one or more candidate target cells and performing user equipment-based timing advance measurements for the plurality of cells according to a first user equipment-based timing advance measurements behavior during a layer 1/layer 2 triggered mobility procedure. An indication to enable a second user equipment-based timing advance measurements behavior may be received. User equipment-based timing advance measurements for the plurality of cells according to the second user equipment-based timing advance measurements behavior based on the indication may be performed.

Abstract: A user equipment (UE) may receive, from a first network entity, an indication of a configuration for the UE to report, to the first network entity, an estimate of a first timing advance value for a second network entity. The UE may determine the estimate of the first timing advance value. The UE may transmit, to the first network entity, the estimate of the first timing advance value for the second network entity or a reference signal time difference associated with the estimate of the first timing advance value. The UE may receive, from the first network entity, an indication of an error value associated with the estimate of the first timing advance value. The UE may determine a second timing advance value based on the estimate of the first timing advance value and the error value. The UE may transmit communications using the second timing advance value.

Abstract: 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.

Abstract: A method is provided that includes receiving a configuration of selection criteria for a timing advance (TA) of a target cell, acquired by respective acquisition schemes including a user equipment (UE)-based acquisition scheme and a random access channel (RACH)-based acquisition scheme. The method includes acquiring a UE-based TA value according to the UE-based acquisition scheme, and transmitting a random access preamble to the target cell that is configured to acquire a RACH-based TA value according to the RACH-based acquisition scheme. The method includes receiving a cell-switch command from a serving cell to trigger a cell switch to the target cell, after the UE-based TA value and the RACH-based TA value are acquired. And the method includes accessing the target cell using a TA value selected from the UE-based TA value and the RACH-based TA value, based on the configuration.

Abstract: 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.

Abstract: 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.

Abstract: Example embodiments of the present disclosure relate to methods, devices, apparatuses and computer readable storage medium for power ramping procedure. In a method, a first apparatus performs a first random access transmission with a transmission power determined based on a power ramping counter. The first random access 5 transmission is associated with a first random access procedure initiated by a physical downlink control channel (PDCCH) order. The first apparatus stores a value of the power ramping counter.
