Embodiment Construction

[0072] In the technical solution provided by the embodiment of the present invention, the core idea is to carry the signaling notifying the UE to activate or deactivate the multi-carrier in the MAC PDU (Protocol Data Unit, protocol data unit) of the MAC layer, based on the MAC CE and the MAC sub The field of -header is used to design the signaling format related to the carrier activation and deactivation process. Specifically, the signaling can be represented by a MAC sub-header indicating the activation and deactivation of all available carriers of the UE, where the LCID adopts one of the currently reserved bit modes, and the R bit indicates that the signaling is an activation signaling The deactivation signal is still used; there is no need to design a special MAC CE field content, that is, the padding bits of the MAC CE corresponding to the MAC sub-header are zero. In addition, the LCID can also be used directly to distinguish the activation signaling from the deactivation ...

Abstract

The embodiment of the invention discloses a method for activating carrier waves, which comprises the following steps of: receiving a media access control protocol data unit (MAC PDU) from a network side, wherein the MAC PDU carries activation information through a media access control sub-header (MAC sub-header) corresponding to a media access control control element (MAC CE); and activating or deactivating the carrier waves configured on the network side according to the activation information carried by the MAC sub-header. The embodiment of the invention saves the electric quantity of user equipment (UE). The embodiment of the invention also discloses a device and a system applying the method.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a carrier activation method, device and system. Background technique [0002] As a subsequent enhanced version of 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) LTE (Long Term Evolution, Long Term Evolution) technology, the LTE-A (LTE Advanced, Advanced Long Term Evolution) system introduces carrier aggregation (carrier aggregation) technology to support higher bandwidth transmissions. [0003] The basic principle of carrier aggregation is to meet higher bandwidth requirements by aggregating two or more working carriers together. After the carrier aggregation technology is introduced, the number of working carriers in a cell changes from one to multiple, forming a multi-carrier communication scenario. In the carrier aggregation technology, multiple working carriers (uplink or downlink) are aggregated together to serve UE (User E...
