Embodiment Construction

[0073] In the embodiment of the present invention, there are two schemes for using a DRX-related timer to perform implicit carrier deactivation, one is UE-based implicit deactivation, and the other is CC-based implicit deactivation. The former method can only deactivate all DL SCCs of the UE, while the latter method can deactivate different DL SCCs respectively.

[0074] At the same time, based on different understandings of the DRX mechanism, the schemes for using DRX-related timers to perform implicit carrier deactivation in the embodiments of the present invention are also different. The carrier deactivation scheme is introduced.

[0075] Embodiment 1 of the present invention provides a method for implicit carrier deactivation, which is applied to the situation of DRX mechanism understanding 1, such as Figure 7 shown, including:

[0076] In step 701, the UE obtains the status of the configured drx-Inactivity timer / HARQ RTTtimer / drx-Retransmission timer; when the statuses...

Abstract

The invention provides an implicit carrier deactivation method and equipment. The method comprises that: when learning that a downlink secondary component carrier (DL SCC) does not have data and control information transmission needs, a user terminal deactivates the DL SCC. The invention also provides an implicit carrier deactivation mechanism in a long term evolution-advanced (LTE-A) system.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and equipment for using a timer to deactivate an implicit carrier. Background technique [0002] In a mobile communication system based on a shared channel, such as LTE (Long Term Evolution, long-term evolution), the transmission of uplink and downlink data is controlled by the eNB (evolved Node-B, base station) scheduler. When the scheduler determines to schedule a certain user , the terminal will be notified on which resource to send or receive data through the control channel. The UE (User Equipment, terminal) monitors the control channel, and when it detects that it contains its own scheduling information, it completes data transmission (uplink) or reception (downlink) according to the instructions on the control channel. In the activated state, since the terminal is not sure when the eNB will schedule it, a common working mode is that the terminal continuously mon...
