Expense is conducive to improve spectrum utilization efficiency.
Fig. 1 is a kind of flow chart for controlling information acquisition method one embodiment of the present invention, and this method may include following
Several steps:
Step 101: terminal detection is currently used in the component carrier of carrier wave polymerization.
The component carrier includes pass with the terminal association of the network side equipment according to control searching carrier rule setting
Joint control carrier wave, the control searching carrier rule include location information of the association control carrier wave in component carrier.
In carrier aggregation technology, the component carrier that can be used for carrier wave polymerization can be continuous frequency spectrum resource, can also
To be discontinuous frequency spectrum resource.Carrier wave polymerization is that can combine multiple component carriers continuously or discontinuously to make together
With providing higher power system capacity to increase bandwidth.
For the component carrier of carrier wave polymerization, some can be used for transmitting control information, and to control carrier wave, some are served only for
Data are transmitted, are data carrier.
And in component carrier, carrying control information control carrier wave may include it is multiple, for access network terminal,
The component carrier that the association being associated controls carrier wave namely terminal is resident is had, different terminals may be associated in together
In one control carrier wave.
Since control information includes uplink/downlink resource allocation information or power control information etc., terminal needs to be believed according to control
Breath carry out data send and receive or power adjustment etc..Terminal needs to obtain the control information of oneself, i.e. its association control
The control information carried in carrier wave, therefore the search of the down control channel in carrier wave polymerization is related generally in the present embodiment, with
It enables the terminal to read the control information in down control channel.
In the present embodiment, network side equipment is carried according to control searching carrier rule setting with the control that is associated with of terminal association
Wave.The control searching carrier rule includes location information of the association control carrier wave in the component carrier.
The control searching carrier rule can be that network side equipment is predetermined, and network side equipment can carry the control
Wave search rule is supplied to terminal.
Since the component carrier polymerizeing for carrier wave may change, but network side equipment is searched according to the control carrier wave
Searching position of the association control carrier wave of rope rule setting in component carrier is constant, so even component carrier becomes
Change, terminal can still determine that the association in present component carrier wave controls carrier wave according to the control searching carrier rule.
Location information of the association control carrier wave in the component carrier as defined in the control searching carrier rule can wrap
Include location information and association control carrier wave location information in control carrier wave of the control carrier wave in component carrier.

When variation, searching position of the association control carrier wave in component carrier is constant.
Terminal can be used for the component carrier of carrier wave polymerization with real-time detection, in order to the current component carrier of determination.
Each carrier wave all has index, and carrier wave can be indicated with carrier index, therefore the component carrier of terminal detection can be with
Including carrier index, while it may further determine that out the carrier number of component carrier, it can be unique according to the carrier index of component carrier
Find corresponding component carrier.
Terminal detection is currently used in the component carrier of carrier wave polymerization, after can be accessing terminal to network side apparatus, network side
Equipment is by the main carrier information of system configuration, the component carrier comprising being currently used in carrier wave polymerization, and currently without using
Main carrier, notify that, to terminal, terminal can determine to be currently used in from the main carrier information component of carrier wave polymerization
Carrier wave.
Certainly other modes can also be used, can be introduced in detail in embodiment below.
Step 102: according to the control searching carrier rule, determining the association control carrier wave in the component carrier.
After terminal detects component carrier, the association in component carrier can be determined according to the control searching carrier rule

When component carrier is indicated with indexing, identified association control carrier wave is the rope for including association control carrier wave
Draw.
Such as terminal component carrier index detected is 1,5,6,7,8,9, control searching carrier rule is component carrier
The 2nd is association control carrier wave in 3 carrier waves of middle low frequency part, and 3 carrier index of low frequency part are 1,5,6, for control
Carrier index, and then can learn that the index of association control carrier wave is 5, so as to carry out subsequent operation on carrier wave 5.
If component carrier changes, component carrier index is 1,2,3,4,5,6, then advises according to the control searching carrier
Then, it can determine that the index of association control carrier wave becomes 2.
Step 103: being detected in association control carrier wave, obtain control information.
After determining association control carrier wave, it can detected in corresponding association control carrier wave, if detection exists
Corresponding control information can be read in control channel.
Such as determine that the index of association control carrier wave is 2, then Channel Detection can be carried out, on carrier 2 to read control
Information processed.
In the present embodiment, terminal detection is currently used in the component carrier of carrier wave polymerization, and according to control searching carrier rule
Then, association control carrier wave in the component carrier is determined, so as to be associated with control load corresponding according to control carrier wave is associated with
It is detected on wave, to obtain control information.Due to being currently used in the component carrier of carrier wave polymerization, network side equipment is also to press
