Description

A kind of method and system of activating component carrier

Technical field

The present invention relates to multicarrier system, in espespecially a kind of multicarrier system, the method and system of activating component carrier.

Background technology

Long Term Evolution (LTE, Long Term Evolution) system Zhong, community only has a up-link carrier and descending carrier.In Long Term Evolution-senior (LTE-A, Long Term Evolution-Advance) stage, in order to improve the transmission rate of up/down row, the up/down row of a LTE-A community can dispose a plurality of component carriers (CC, Component Carrier).

Suppose that there are a plurality of up/down row component carriers a LTE-A community, so, in community one in the LTE-A of idle condition terminal, in order to simplify the behavior of idle-state terminals, the power consumption that reduces terminal, idle-state terminals always resides on some component carriers.But, when LTE-A terminal enters after connection status, in order to allow LTE-A terminal transmit with higher speed, the process that need component carrier configuration, activates, so that carrier wave is managed, thereby allow LTE-A terminal can on a plurality of component carriers, carry out data dispatch simultaneously.So, when LTE-A terminal enters connection status from idle condition, need to go to obtain by certain mode the system configuration information of other component carrier except resident carrier wave or service carrier wave.The system configuration information of these carrier waves comprises Physical Cell Identifier (PCI, Physical Cell ID), frequency, the bandwidth of component carrier, the information such as common radio resources configuration information of component carrier.In LTE system, these information are all to broadcast in Master Information Block (MIB, Master Information Block)/system information block 1 (SIB1, SystemInformation Block)/SIB2.But in LTE-A system, terminal, in order to obtain the system configuration information of other component carrier except resident carrier wave or service carrier wave, has three kinds of solutions at present.

Scheme one, on the resident component carrier of LTE-A terminal, the system information of the component carrier that broadcast cell is all.Like this, the LTE-A terminal of idle condition just can be obtained the up-to-date system information of all component carriers.After LTE-A terminal enters connection status from idle condition, the system information of other component carrier that directly just can provide according to resident carrier wave is dispatched on other component carrier.Scheme one defect is clearly, on the resident component carrier of LTE-A terminal, system message amount is very large, has taken a lot of resources.

Scheme two, allows the LTE-A terminal of idle condition read the system message of all component carriers in community, and when existing component carrier system cell to change, LTE-A terminal reads the system message on this component carrier immediately.Like this, when LTE-A terminal is from idle condition enters connection status, LTE-A terminal is the up-to-date system message of each component carrier according to what obtain, on these component carriers, dispatches.Scheme two is mainly the ability that has strengthened idle-state terminals, still, owing to need to monitoring at any time the beep-page message of the system message modification of all component carriers, has caused the larger problem of LTE-A terminal power consumption.

Scheme three, from idle condition enters connection status, notifies the system information of the component carrier of its use of LTE-A terminal in LTE-A terminal by dedicated signaling.These system informations at least comprise Physical Cell Identifier (PCI, Physical Cell ID), frequency, bandwidth, the common radio resources configuration information of component carrier and the component carrier dedicated radio resources configuration information that LTE-A terminal is used etc. of component carrier.

Fig. 1 is the flow chart of the Activiation method of existing scheme three, and as shown in Figure 1, it is upper that terminal RRC connection is based upon F1/F4, and on F1/F4, UE is carried out to scheduling of resource (step 100~step 101); Suppose as required, evolution base station eNodeB passes through activation command, the component carrier F2/F5 that activated terminals is used, in activation command, carry all system informations and the dedicated radio resources configuration information (step 102) of F2/F5, UE returns to carrier activation success response afterwards, and on F1/F4 and F2/F5, UE is carried out to scheduling of resource (step 103~step 104).Suppose as required, eNodeB passes through activation command, activated terminals is used component carrier F3/F5, deexcitation F2/F5, now, the all system informations and the dedicated radio resources configuration information (step 105) that in activation command, carry F3/F5, UE returns to carrier activation success response afterwards, and on F1/F4 and F3/F5, UE is carried out to scheduling of resource (step 106~step 107).Suppose afterwards more as required, eNodeB passes through activation command, activated terminals is used component carrier F2/F5, deexcitation F3/F5, in activation command, again carry all system informations and the dedicated radio resources configuration information (step 108) of F2/F5, UE returns to carrier activation success response, and on F1/F4 and F2/F5, UE is carried out to scheduling of resource (step 109~step 110).From the flow process shown in Fig. 1, during each activating component carrier, all need to carry the bulk information of new activation carrier wave.

Equally, after switching completes, for terminal can be dispatched on a plurality of component carriers, also need terminal by obtaining someway the system configuration information of a plurality of component carriers of Target cell.At this moment, can use the thought of such scheme three, in switching command, the component carrier dedicated radio resources configuration information that the common radio resources configuration information of the PCI of the component carrier that carried terminal is used in Target cell, frequency, bandwidth, component carrier and terminal are used.

Fig. 2 is the existing flow chart that utilizes the method for the activating component carrier of scheme three after UE has switched, as shown in Figure 2, UE completes the switching from source eNodeB to target eNode B, use component carrier F1/F4, hypothetical target eNodeB passes through activation command, activate the component carrier F2/F5 that UE is used, in activation command, carry all system informations and the dedicated radio resources configuration information of F2/F5, UE returns to carrier activation success response afterwards, and on F1/F4 and F2/F5, UE is carried out to scheduling of resource (step 200~step 203).Suppose as required, activation command is passed through in base station, the component carrier F3/F5 that activated terminals is used, deexcitation F2/F5, in activation command, carry all system informations of F3/F5 and dedicated radio resources configuration information, UE returns to carrier activation success response, and on F1/F4 and F3/F5, UE is carried out to scheduling of resource (step 204~step 206).Suppose afterwards more as required, activation command is passed through in base station, activate the component carrier F2/F5 that UE is used, deexcitation F3/F5, need again again in activation command, to carry all system informations of F2/F5 and dedicated radio resources configuration information, UE returns to carrier activation success response, and on F1/F4 and F2/F5, UE is carried out to scheduling of resource (step 207~step 209).Same, from the flow process shown in Fig. 2, can find out, during each activating component carrier, all need to carry the bulk information of new activation carrier wave.
