Carrier aggregation technology is that subscriber equipment can work on multiple community simultaneously, a community comprises a pair UL (up link)/DL (down link) CC (member carrier, Component Carrier), instead of in LTE system and wireless communication system before, only have the pattern of a set of carrier wave.In the system of carrier aggregation, each member carrier can be continuous, and also can be discrete, the bandwidth between each member carrier can be identical or different, and in order to keep compatible with LTE system, the maximum bandwidth of each member carrier is restricted to 20MHz.It is generally acknowledged that the community number maximum number that subscriber equipment can be polymerized is 5 at present.In addition, LTE-A also classifies to the community of carrier aggregation, is divided into:
PCell (Primary Cell, main plot): terminal is polymerized in multiple community and is only had a community to be defined as Pcell, Pcell by base station selected, and passes through RRC (Radio Resource Control, wireless heterogeneous networks) signal deployment to terminal.Only have on Pcell and be configured with PUCCH (Physical Uplink ControlChannel, physical layer ascending control channel);
SCell (auxiliary community, Secondary Cell): the community in all communities of terminal polymerization except Pcell is all SCell.
In CA system, the processes such as some cell managements (such as delete a Ge Fu community, reprovision one Ge Fu community, activation/deactivation one Ge Fu community, Serving cell signal quality report) need often the aggregation cell of UE is retrieved.Community within the scope of a polymerization uniquely can be determined by frequency and PCI (Physical cellID, physical cell identity).From the angle of signaling consumption, can avoid reusing carrier frequency and these two parameters of PCI in a large number by introducing cell number parameter.Determined the cell number parameter introducing UE rank in current standard discussion, be encoded to 3bit, the numbering of a community will while this community newly-increased by network allocation to UE.The cell number of main plot is fixed as 0, and the community label scope of application of auxiliary community is 1 ~ 7.
Business due to subscriber equipment may have fluctuation and sudden, namely in certain period, traffic carrying capacity is little, and traffic carrying capacity is very large in certain period, when user apparatus service amount is fewer time, in order to better economize on electricity, lte-a system introduces the concept of activation/deactivation, and the Pell of regulation UE does not allow to be deactivated, acquiescence is in state of activation always, and can carry out activation/deactivation operation to Scell.
For the carrier wave of deexcitation, UE does not need to perform PDCCH (Physical Downlink ControlChannel, physical downlink control channel) monitoring/PDSCH (Physical Downlink SharedChannel, physical down link sharing channel) receive, do not need to send PUSCH (Physical UplinkShared Channel, physical uplink link shared channels)/SRS (Sounding Reference Signal, detection reference signal)/CQI (Channel Quality Indicator, channel quality indicates) etc., so just can reach better power savings.
LTE-A R11 is based on improving spectrum efficiency, better supporting to determine the consideration of Hetnet (heterogeneous network) scene and economize on electricity to do downlink transfer to strengthen, introduce a kind of new descending carrier, be referred to as descending expansion carrier wave here.
Introduce because expansion carrier wave is new in lte-a system, at present not for measurement and the synchronization scenario of expansion carrier wave.
