Document Type and Number:
WIPO Patent Application WO/2016/161548
Kind Code:
A1
Abstract:
A method and apparatus for deactivating a secondary cell, and a communication system. The deactivation method comprises: in the case where a deactivation timer is restarted or a channel quality indication report is transmitted in any one of second secondary cells of a secondary PUCCH cell group, restarting a deactivation timer associated with a first secondary cell which carries a PUCCH. Thereby, the situation where a user equipment and a base station have an inconsistent understanding of an activated state of a secondary cell, which is caused by an autonomous deactivation mechanism of the user equipment, cannot occur.
