Description
Technical field
The present invention relates to wireless communication technology field, relate in particular to a kind of method, system and device of transfer of data.
Background technology
Third generation partner program (3rd Generation Partnership Project, mobile cellular communication of future generation system 3GPP) (Long Term Evolution-Advanced, LTE-Advanced) in; In order to improve the throughput of system; Introduced carrier aggregation (Carrier Aggregation, CA) technology is in the promptly same sub-district; (Component Carrier CC) gathers together with a plurality of member carriers.When carrying out data quantity transmitted when bigger with the terminal in the LTE-A system, need simultaneously in the enterprising data transfer of a plurality of CC, to improve the speed of transfer of data.The terminal is when adopting these a plurality of CC to carry out transfer of data; Need monitor downlink physical control channel (the PhysicalDownlink Control Channel of the bearing downlink control signaling on these a plurality of CC simultaneously; PDCCH); With the downlink physical shared channel of bearing downlink data (Physical Downlink Shared Channel, PDSCH).
Figure 1A is for being a plurality of CC structural representations of parameter with frequency f and time t in the prior art; The carrier sense of in the LTE-A system, adopting is machine-processed as follows: PDCCH and PDSCH on terminal monitoring the one CC, and a CC is also referred to as anchor CC, like the CC1 among the figure; When lot of data need be transmitted with this terminal; The CC that network side is being monitored through this terminal sends the control signaling that starts monitoring the 2nd CC to the terminal, i.e. CC2, CC3 and CC4 among the figure; Terminal this control signaling through receiving at a CC; Startup is to the monitoring of the 2nd CC, and according to the system message of this each CC that listens to, adopts a CC and the 2nd CC polymerization to carry out the transmission of data with network side.
