A method at a network node, comprising: configuring first control information of a first type of control channel, which indicates data required by a user equipment UE in a first state on a data channel; configuring second control information of a second type of control channel, which indicates data required by the UE in a second state on the data channel; transmitting only the first control information on the first type of control channel to the UE, when the UE is in the first state; and transmitting only the second control information on the second type of control channel to the UE, when the UE enters the second state from the first state, wherein configuration information of the second type of control channel is included in the data required by the UE in the first state which are indicated by the first control information of the first type of control channel, before the UE enters the second state from the first state, wherein the first type of control channel is any one of a non-active-mode control channel and an active-mode control channel, and the second type of control channel is any another one of the non-active-mode control channel and the active-mode control channel, and wherein control information of the non-active-mode control channel indicates non-UE-dedicated data on the data channel, and control information of the active-mode control channel indicates UE-dedicated data on the data channel, and wherein the first state of the UE is either of an Idle or Dormant state and an Active state, and the second state of the UE is the other of the Idle or Dormant state and the Active state, and wherein the data required by the UE in the Idle state and the Dormant state are non-UE-dedicated data indicated by the control information of the non-active-mode control channel, and the data required by the UE in the Active state are UE-dedicated data indicated by the control information of the active-mode control channel. configuring first control information of a first type of control channel, which indicates data required by a user equipment UE in a first state on a data channel; configuring second control information of a second type of control channel, which indicates data required by the UE in a second state on the data channel; transmitting only the first control information on the first type of control channel to the UE, when the UE is in the first state; and transmitting only the second control information on the second type of control channel to the UE, when the UE enters the second state from the first state, wherein configuration information of the second type of control channel is included in the data required by the UE in the first state which are indicated by the first control information of the first type of control channel, before the UE enters the second state from the first state, wherein the first type of control channel is any one of a non-active-mode control channel and an active-mode control channel, and the second type of control channel is any another one of the non-active-mode control channel and the active-mode control channel, and wherein control information of the non-active-mode control channel indicates non-UE-dedicated data on the data channel, and control information of the active-mode control channel indicates UE-dedicated data on the data channel, and wherein the first state of the UE is either of an Idle or Dormant state and an Active state, and the second state of the UE is the other of the Idle or Dormant state and the Active state, and wherein the data required by the UE in the Idle state and the Dormant state are non-UE-dedicated data indicated by the control information of the non-active-mode control channel, and the data required by the UE in the Active state are UE-dedicated data indicated by the control information of the active-mode control channel.
