Abstract

A method and an apparatus for controlling a channel transmission status, can be used in the communication field. The method includes receiving a command for controlling activation of a secondary carrier. Within a preset delay time after the secondary carrier is activated, a channel transmission status corresponding to the secondary carrier to a continuous transmission status can be set.

updating the channel transmission status corresponding to the secondary carrier according to an updated status of the common UE_DTX_DRX_Enable.

9. The method according to claim 1, wherein setting, after the channel transmission status comprises:

setting a common uplink discontinuous transmission activated variable (UL_DTX_Active) for a primary carrier and the secondary carrier;

setting, within the preset delay time after the secondary carrier is activated, a status of the common UL_DTX_Active to a deactivated status; and

setting the channel transmission status corresponding to the secondary carrier according to the status of the common UL_DTX_Active.

10. The method according to claim 9, further comprising:

updating, after the preset delay time, the status of the common UL_DTX_Active to a status same as a status of corresponding UL_DTX_Active before the secondary carrier is activated; and

updating the channel transmission status corresponding to the secondary carrier according to an updated status of the common UL_DTX_Active.

11. The method according to claim 1, further comprising:

updating, after the preset delay time, the channel transmission status corresponding to the secondary carrier according to at least one of the status of the common UE_DTX_DRX_Enabled and the status of the status of the UL_DTX_Active.

12. The method according to claim 1, wherein a value of the preset delay time is equal to one of a value of an enabling delay parameter in a discontinuous transmission and discontinuous reception parameter, a value of an enabling delay parameter separately set by a network side for the secondary carrier, and a preset fixed delay value.
