Abstract: Provided are method, system, and device for configuring inter-cell changes. The method may be implemented by receiving, by a user equipment (UE), a downlink signal, wherein the downlink signal originates from a serving distributed unit (DU), and wherein the downlink signal comprises at least one of a scheduling gap duration value, a start time value, and a target cell index; performing, by the UE during the scheduling gap duration, an uplink sync with a target cell, based on the downlink signal; and wherein the uplink sync includes sending, by the UE, a preamble transmission to a target cell to acquire a timing advance of the target cell, based on the downlink signal, wherein the target DU is one of a plurality of neighboring cells to the serving DU.

Abstract: A method performed by at least one processor in a user equipment (UE), the method including receiving, from a base station over a channel, a plurality of reference signals corresponding to a state of the channel. The method further including measuring a subset of the received plurality of reference signals. The method further including transmitting, to the base station within a first time interval, a channel status report corresponding to the measuring of the subset of the received plurality of reference signals and a prediction of one more reference signals received by the UE after the first time interval.

Abstract: A method includes sending a first set of one or more probing messages to a UE, the first set of the one or more probing messages including a set of reference signals. The method includes receiving, in response to the first one or more probing messages, a first channel state information (CSI) report from the UEs that includes first CSI derived from measurements of the set of reference signals. The method includes sending, a second set of one or more probing messages to the UE, the second set of the one or more probing messages including a subset of the reference signals. The method further includes receiving, in response to the second set of one or more probing messages, a second CSI report that includes second CSI derived from measurement of the subset of the reference signals.
