Embodiment Construction

[0075] In the extended carrier processing method, base station, and user equipment in the carrier aggregation system of the embodiment of the present invention, when data needs to be loaded on the extended carrier, the base station loads the control information and the first data information on the primary component carrier at the first moment , and at the second moment (the difference between the second moment and the first moment is greater than 0), the second data information is loaded on the extension carrier, and the user equipment receives the second data information according to the second moment.

[0076] Such as image 3 As shown, the processing method of the extended carrier in the carrier aggregation system according to the embodiment of the present invention, from the perspective of the base station, includes:

[0077] Step 31, the base station loads and sends control information and first data information on the primary component carrier from the first moment;

Abstract

The invention provides a method for processing an extended carrier in a carrier polymerization system, a base station and user equipment, wherein the processing method is used for an LTE-A (Long Term Evolution-Advanced) system and comprises the following steps: the base station begins to load and send control information and first data information on a main component carrier from a first time; the base station begins to load and send second data information on the extended carrier from a second time while the data is needed to be loaded on the extended carrier, wherein the difference between the second time and the first time is more than 0; and the base station informs the user equipment of the difference between the second time and the first time. According to an embodiment of the invention, the power consumption of the user equipment is reduced while no data transmission exists on the extended carrier.

Description

technical field [0001] The present invention relates to an LTE-A (Long Term Evolution-Advanced, Advanced Long Term Evolution) system, in particular to a method for processing extended carriers in a carrier aggregation system, a base station and user equipment. Background technique [0002] The LTE (Long Term Evolution, long-term evolution) system defines the PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel) used to carry scheduling allocation and control information. The PDCCH can contain up to 3 OFDM (Orthogonal Frequency Division Multiplexing, orthogonal frequency division multiplexing) symbol. The PCFICH (Physical Control Format Indicator Channel, Physical Control Format Indicator Channel) is used to indicate the number of OFDM symbols occupied by the PDCCH in the subframe; the PDSCH (Physical Downlink Shared Channel, Physical Downlink Shared Channel) is used to carry downlink data information. [0003] In an LTE-A (Long Term Evolution-Advanced...
