A method of configuring a channel carrier by a user equipment, comprising: receiving a message carrying channel carrier configuration information sent by a base station, wherein the channel carrier configuration information indicates numerology and/or transmission time interval configuration information for a plurality of carriers associated with a logical channel; and determining each of the plurality of carriers mapped to the logical channel and a numerology and/or a transmission time interval configured for each of the plurality of carriers mapped to the logical channel, based on the channel carrier configuration information; wherein receiving the message carrying the channel carrier configuration information sent by the base station comprises: receiving a Radio Resource Control, RRC, message carrying the channel carrier configuration information sent by the base station; and characterized in that , wherein when the RRC message is an RRC message instructing user equipment to switch to an inactive state, the RRC message further carries respective numerologies and/or transmission time intervals configured for the plurality of carriers associated with the logical channel; and the method further comprises: determining a carrier for a cell when the user equipment in the inactive state resides in the cell; and determining a numerology and/or a transmission time interval configured for the carrier for the cell with respect to the logical channel, based on the carrier for the cell. receiving a message carrying channel carrier configuration information sent by a base station, wherein the channel carrier configuration information indicates numerology and/or transmission time interval configuration information for a plurality of carriers associated with a logical channel; and determining each of the plurality of carriers mapped to the logical channel and a numerology and/or a transmission time interval configured for each of the plurality of carriers mapped to the logical channel, based on the channel carrier configuration information; wherein receiving the message carrying the channel carrier configuration information sent by the base station comprises: receiving a Radio Resource Control, RRC, message carrying the channel carrier configuration information sent by the base station; and characterized in that , wherein when the RRC message is an RRC message instructing user equipment to switch to an inactive state, the RRC message further carries respective numerologies and/or transmission time intervals configured for the plurality of carriers associated with the logical channel; and the method further comprises: determining a carrier for a cell when the user equipment in the inactive state resides in the cell; and determining a numerology and/or a transmission time interval configured for the carrier for the cell with respect to the logical channel, based on the carrier for the cell. determining a carrier for a cell when the user equipment in the inactive state resides in the cell; and determining a numerology and/or a transmission time interval configured for the carrier for the cell with respect to the logical channel, based on the carrier for the cell. <EOS>
