Claim 22:
23. A method for user equipment, comprising
communicating with a base station via a plurality of component carriers with carrier aggregation, each component carrier of the plurality of component carriers corresponding to a cell in a plurality of cells,
wherein a first cell among the plurality of the cells provides non access stratum (NAS) mobility information to the user equipment,
wherein one or more other cells among the plurality of the cells, different from the first cell, provide uplink and/or downlink resources to the user equipment, and
wherein the one or more other cells, different from the first cell, include a second cell that is activated for the user equipment; and
in response to a change in system information for the second cell that is activated for the user equipment, receiving first information, which comprises updated system information for the second cell, via a dedicated signaling through the first cell such that the electronic device at the user side need not acquire the updated system information from a broadcast channel of the second cell,
wherein the updated system information for the second cell comprises one or more of:
uplink Power Control information associated with the second cell,
soundingRS-UL-Config information associated with the second cell, or
ul-CyclicPrefixLength information associated with the second cell.
