Between, and DCI is sent to user equipment 20 using determining search space.
Below according to the corresponding relationship of search space and Goal time order, a point situation is illustrated:
Situation one, the network side equipment determine that first timing corresponds to the public search space, determine described
Two timing correspond to the specific search space the UE.
Determine that network side equipment 10 passes through public affairs when needing to indicate user equipment 20 using the first timing in network side equipment 10
Search space sends DCI to user equipment 20 altogether；When the determination of network side equipment 10 needs to indicate user equipment 20 using second
When sequence, network side equipment 10 sends DCI to user equipment 20 by the specific search space UE.
Correspondingly, user equipment 20 detects the DCI that network side equipment 10 is sent, sending DCI according to network side equipment 10 makes

The public search space of the embodiment of the present invention is used for transmission and Paging (paging message), RAResponse
(Random access Response, random accessing message), BCCH (Broadcast Control Channel, Broadcasting Control
Channel) etc. relevant Downlink Control Information (public information of cell level), which is the same for all UE.UE
Specific search space is used for transmission and DL-SCH (Downlink share channel, DSCH Downlink Shared Channel), UL-SCH
The relevant control information (information of UE rank) such as (Uplink share channel, Uplink Shared Channel).But when UE is special
When fixed search space does not have enough available resources, public search space can be used for the control that transmission belongs to some particular UE
Information processed.But public search space is only used for transmitting lesser DCI format (format) 0/1A/3/3A/1C.Therefore, public
Search space and the specific search space UE might have overlapping region.
The search space that the DCI that network side equipment 10 is sent is used is determined for the ease of user equipment 20, and the present invention is implemented
Example network side equipment sends different size of DCI in different search spaces, so that user equipment 20 is according to the DCI's detected
Size determines the search space that the DCI that network side equipment is sent is used.
A point situation is illustrated below:

The network side equipment 10 of the embodiment of the present invention is after determining Goal time order, according to pair of Goal time order and search space
It should be related to, determine and send the search space that DCI is used.If the determination of network side equipment 10 sends DCI in the specific search space UE,
Then network side equipment 10 sends x bit DCI in the specific search space UE；If network side equipment 10 is determined in public search space
Middle transmission DCI, then network side equipment 10 sends the DCI for increasing y cover bit in public search space, i.e., in common search
X+y bit DCI is sent in space.
Correspondingly, user equipment 20 needs to detect network side equipment respectively in public search space and the specific search space UE
10 DCI sent, the DCI that user equipment 20 is sent using following manner detection network side equipment 10:
Optionally, the user equipment is sent in the public search space using x+y bit-detection network side equipment
DCI, in the DCI that the specific search space the UE uses x bit-detection network side equipment to send.
Optionally, the cover bit y=1 and y cover bit is 0.
User equipment of the embodiment of the present invention 20 carries out detecting it in the different size of DCI that different search spaces uses
Afterwards, the user equipment determines that network side equipment 10 sends the search space that DCI is used, tool according to the size of the DCI detected
Body:

The search space that standby 10 transmission DCI is used is public search space；If user equipment 20 detects what network side equipment 10 was sent
The size of DCI is x bit, it is determined that it is the specific search space UE that network side equipment 10, which sends the search space that DCI is used,.
Optionally, cover bit is located at the end position of DCI information bit.
It should be noted that, since public search space being not present in secondary carrier, network side is set in multi-carrier transmission
The standby specific search space UE by secondary carrier sends DCI to user equipment 20, can specifically be sent using following manner:
Mode one, the network side equipment send x bit DCI in the specific search space UE of secondary carrier；
Correspondingly, the user equipment is sent out in the specific search space UE of secondary carrier using x bit-detection network side equipment
The DCI sent.
The transmission x+y bit DCI in the specific search space UE of mode two, the network side equipment secondary carrier；
Correspondingly, the user equipment uses x+y bit-detection network side equipment in the specific search space UE of secondary carrier
The DCI of transmission.
It is described in detail below with two implementations.
Example one:
The embodiment of the present invention is single carrier transmission.If network side equipment 10 sends DCI instruction using public search space and uses
