1. A wireless communication device, comprising:
a transmitter configured to transmit, to another wireless communication device, a downlink data signal at a time unit n, the downlink data signal comprising an activation or deactivation command acting on a secondary cell; and
a receiver configured to receive an uplink control signal carrying the HARQ-ACK information corresponding to the downlink data signal, transmission of the uplink control signal corresponding to a time unit which is a time unit n+k+1 or a time unit n+k, the time unit n+k+1 is time that the another wireless communication device applies corresponding action not earlier than or the another wireless communication device applies applying actions related to a deactivation timer of the secondary cell, the time unit n+k relating to timing that the another wireless communication device applies actions related to a CSI report which is related to or corresponds to the activation or deactivation command, wherein
the k is obtained through calculation by using a formula as below:
k=k′1+3Nslotsubframe,μ;
where,
Nslotsubframe,μ refers to the number of slots contained in each subframe when SCS (subcarrier spacing) configuration corresponding to transmission of the uplink control signal is μ, and
k′1 refers to the slot offset or offset between the downlink data signal and the uplink control signal carrying the HARQ-ACK information corresponding to the downlink data signal.
