This application is a continuation application of U.S. patent application Ser. No. 16/959,770 filed on Jul. 2, 2020, which is the U.S. national phase of PCT Application PCT/CN2018/125477 filed on Dec. 29, 2018, which claims priority to Chinese Patent Application No. 201810009128.2 filed on Jan. 4, 2018, which are incorporated herein by reference in their entireties.
The present disclosure relates to the field of communication technologies, and more particularly, to a state processing method, a user equipment and a base station.
Long term evolution LTE systems introduce carrier aggregation techniques. A carrier technology is that a user equipment UE connects and communicates with a network through a plurality of cells, one cell is a primary cell (PCell) and the other cells are secondary cells (SCells). The SCell may be in the activated/deactivated state and PCell may not be in a deactivated and remains activated.
When the base station adds one or more SCell through RRCConnectionReconfiguration (RRC connection reconfiguration message), the initial state of these SCells is deactivated; similarly, in the handover scenario, the target base station sends the SCell configuration information to the source base station through the HandoverCommand (handover command). When the source base station forwards the SCell configuration information to the UE through the RRCConnectionReconfiguration, the initial states of all the SCells are deactivated.
