Method of applying discontinuous reception operation and related communication device

摘要

A method of applying DRX operation for a mobile device in a wireless communication system is disclosed. The mobile device is configured with a primary serving cell and at least one secondary serving cell, and the DRX operation is already applied to the activated serving cell (e.g. primary serving cell), but not applied to the deactivated serving cell. The method comprises receiving a control element, wherein the control element is used for activating the at least one secondary serving cell; and applying the DRX operation to the at least one secondary serving cell when this serving cell's activation/deactivation state has just been changed from deactivation to activation state according to the control element.

1. A method of applying discontinuous reception (DRX) operation for a mobile device in a wireless communication system, the method comprising:
the mobile device being configured with a primary serving cell and at least one secondary serving cell which is deactivated; the mobile device applying the DRX operation to the primary serving cell; the mobile device not applying the DRX operation to the at least one secondary serving cell which is deactivated; when the mobile device receives, upon the at least one secondary serving cell being deactivated and the DRX operation having been applied on the primary cell, an activation MAC (Medium Access Control) control element for activating the at least one secondary serving cell, applying the DRX operation to the at least one secondary serving cell according to the activation MAC control element; and applying the DRX operation on the primary serving cell and the activated at least one secondary serving cell when a DRX Inactivity Timer expires.
