In LTE-A cordless communication networks, base station is also referred to as e nodes B (i.e. eNB).Fig. 2 shows the flow chart of the method for the base station activation carrier component according to an embodiment of the invention in cordless communication network.According to Fig. 2, in step 201, the carrier component information on multiple uplink carrier components being included in switching command is sent to user equipment.In step 202, one of uplink carrier component of the user equipment selection is activated.In step 203, the downlink carrier component matched with one of uplink carrier component of the selection is activated, so that the user equipment accesses Target cell.
In one embodiment, after the user equipment accesses the Target cell, activate the remaining uplink carrier component in the multiple uplink carrier component and match somebody with somebody with it
To downlink carrier component.
In one embodiment, the remaining uplink carrier component in the multiple uplink carrier component of medium education signaling activation and the downlink carrier component matched with it are passed through.
In one embodiment, the downlink carrier component matched by one of uplink carrier component of dedicated signaling inquiry and the selection of SIB2 information or user equipment, to activate the downlink carrier component.
Fig. 3 shows the flow chart of the method according to an embodiment of the invention that carrier component is activated in the user equipment of cordless communication network.According to Fig. 3, in step 301, the carrier component information that wave component is planted on multiple up-links in being included in switching command is received from base station.In step 302, based on the carrier component information, one of them of the multiple uplink carrier component is selected.In Bu Sudden 303, when one of uplink carrier component of the selection and its downlink carrier component of pairing are activated, Target cell is accessed.
Describe to be used for the method that selection uplink carrier component is transmitted for PRACH within a wireless communication network according to an embodiment of the invention below.
Fig. 4 shows user equipment selection uplink carrier component according to an embodiment of the invention for the flow chart of the method for transmission.According to Fig. 4, in step 401, the uplink carrier component that the downlink carrier component of its pairing is activated is determined from the uplink carrier component of activation.In step 402, the uplink carrier component transmitted for Physical Random Access Channel PRACH is selected from the uplink carrier component of the determination.
According to one embodiment of present invention, one of which in the following manner come select for PRACH transmit uplink carrier component：
(1) user equipment selection carries the uplink carrier component of the pairing downlink carrier component of activation, and the uplink carrier component provides earliest PRACH transmission time slots to accelerate PRACH processes.If there is multiple such uplink carrier components, then the uplink carrier component of the best pairing with activation can be selected first；
(2) user equipment can be randomly chosen uplink carrier component, unique to require
It is, the pairing downlink carrier component of selected uplink carrier component should also be as being activated.
