US 2018/0027461 A1 · Deactivation Method and Apparatus for a Secondary Cell and Communications System

Abstract

A deactivation method and apparatus for a secondary cell and a communications system. The deactivation method includes: restarting a deactivation timer associated with a first SCell carrying a PUCCH, in a case where a deactivation timer is restarted or a channel quality indicator report is transmitted in any second SCell in a secondary PUCCH cell group. Hence, a case will not occur where understanding of an activation state of a secondary cell by a UE and a base station is inconsistent due to an UE autonomous deactivation mechanism.

Claims11

Dependent claims

A deactivation apparatus for a secondary cell (SCell), configured in a user equipment (UE), the UE being configured with a first SCell carrying a physical uplink control channel (PUCCH) and a second SCell carrying no PUCCH;

wherein the deactivation apparatus comprises:
a configuring unit configured to configure the first SCell carrying a PUCCH to be deactivated by a deactivation media access control (MAC) control element (CE);
and the first SCell carrying the PUCCH is configured as not operating a deactivation timer, or a value of a deactivation timer of the first SCell is configured as being greater than a value of a deactivation timer of the second SCell.

A deactivation apparatus for an SCell, configured in a UE, the UE being configured with a first SCell carrying a PUCCH and a second SCell carrying no PUCCH, the first SCell and one or more second SCells whose uplink control information is transmitted via the PUCCH of the first SCell constituting a secondary PUCCH cell group;

the UE being further configured with a primary cell (PCell) carrying a PUCCH, the PCell and one or more second SCells whose uplink control information is transmitted via the PUCCH of the PCell constituting a primary PUCCH cell group;
wherein the deactivation apparatus comprises:
a configuring unit configured to configure the secondary PUCCH cell group with a secondary cell group deactivation timer;
and
a restarting unit configured to restart the secondary cell group deactivation timer in a case where any SCell of the secondary PUCCH cell group satisfies a timer restart condition.
