Embodiment
Embodiments of the invention are described below with reference to accompanying drawing.
(1) the first carrier type (reference picture 1)
As shown in figure 1, the bandwidth of the carrier wave includes the first subband, the second subband 1 and the second subband 2.In the present embodiment,
Second subband is divided into two parts, that is, the second subband 1 and the second subband 2, the first subband are located at the second subband 1 and the second son
Between band 2.It will be understood by those skilled in the art that the other positions relation of the first subband and the second subband is also feasible.
For existing user equipment (that is, the lowest version user equipmenies of release below 12)
If existing user equipment is in idle condition, then, it can reside in the cell with structure shown in Fig. 1
In (carrier wave).For the user equipment, due to only indicating the band of the first subband in MIB (MasterInformation Block)
Width, therefore it thinks that the downlink bandwidth of the cell is the bandwidth of the first subband.The user equipment can with the prior art
Reception system information and beep-page message.
When existing user equipment wants to enter into RRC connection status, it is able to carry out Stochastic accessing to set up RRC connections.Should

On highest version user equipment
For such user equipment, when it is in Idle state, it can be resided in structure shown in Fig. 1
In cell (carrier wave).Now the user equipment thinks that the cell is identical with existing cell.
When the user equipment wants to enter into RRC connection status, it is able to carry out Stochastic accessing to set up RRC connections and energy
Enough receiving random access responses on the first subband.
When base station obtains the ability of the user equipment, namely know that the user equipment is release 12 and the use of the above
After the equipment of family, the base station is the dispatching user facility resource on whole carrier wave.The scheduling of resource can pass through following two modes
Realize：
1. reference picture 2, base station can be the resource that the user equipment is distributed on whole carrier wave by PDCCH.Specifically, base
Stand and Downlink Control Information (DownlinkControl Information, DCI) is transmitted on PDCCH to the user equipment, should
DCI includes the PRB indexes after extension, the position for indicating the PRB that this base station is distributed for the user equipment.Because base station can
The resource that user equipment is distributed on whole carrier wave is thought, accordingly, it would be desirable to be extended to existing PRB indexes.
User equipment is obtained on PDCCH after the DCI corresponding to this user equipment from base station, according in the DCI
PRB index informations and Modulation and Coding Scheme (Modulation and Coding Scheme, MCS) after extension, in the rope
The data from base station are demodulated on the indicated PRB of fuse breath.Due to there is no CRS (Cell-specific in the second subband
Reference signal), it is used to demodulate using DMRS therein (Demodulationreference signal).
In addition, before base station is dispatching user facility resource, base station can be sent out by high-level signaling, such as RRC signaling
Available sub-band information is sent to the user equipment, for its available subband of the notification of user equipment, so, user equipment to be with regard to energy
Enough know the correct bit number of the resource allocation in DCI.
In the present example, in the second subband PDSCH (Physical Downlink SharedChannel) starting character
Number since 0.
2. reference picture 3, base station can be that the user equipment is distributed by EPDCCH resource blocks collection (EPDCCH-PRB-set)
Resource on whole carrier wave.The EPDCCH resource block collection can be only fitted in the first subband or the second subband.
Specifically, DCI is transmitted to the user equipment in base station on EPDCCH resource blocks collection (i.e. in EPDCCH), in the DCI
Including the PRB indexes after extension, the position for indicating the PRB that this base station is distributed for the user equipment.User equipment exists
Obtained on EPDCCH resource block collection after the DCI corresponding to this user equipment from base station, after the extension in the DCI
PRB index informations and Modulation and Coding Scheme (MCS), demodulate the number from base station on the PRB indicated by the index information
According to.
In addition, before base station is dispatching user facility resource, base station can be sent out by high-level signaling, such as RRC signaling
Available sub-band information is sent to the user equipment, for its available subband of the notification of user equipment, so, user equipment to be with regard to energy
Enough know the correct bit number of the resource allocation in DCI.
In the present example, the primary sign of the PDSCH in the second subband is since 0.If EPDCCH resource blocks collection is configured
In the second subband, then the primary sign of EPDCCH resource block collection is since 0.
In the first carrier type, due to comprised only in the second subband limit reference signal (for example, DMRS) and
Do not include System information block, paging and PSS/SSS (PrimarySynchronization Signal/Secondary
Synchronization Signal), therefore, efficient resource unit for data transfer in the first subband compared to having increased
Plus.Therefore, the carrier type results in higher end user throughput and spectrum efficiency.Also, the carrier type allows
Existing user equipment is resident and accesses.
Favourable, base station can also adjust the bandwidth of the first subband based on different scenes.If for example, covering in base station
There is greater number of lowest version user equipment in the range of lid, then base station can be the larger bandwidth of the first subband arrangement, for example
75PRB；If there is greater number of highest version user equipment in the coverage of base station, then base station can be the first subband
Configure less bandwidth, such as 15PRB.
(2) second of carrier type (reference picture 4)
Include PSS/SSS in the carrier wave of this type, its time/frequency location can be with position phase of the prior art
Together, or it can also in a standard be defined and (define different positions).
The carrier wave includes PBCH (Physical Broadcast Channel), and its time/frequency location can be with showing
There is the position in technology identical (as shown in Figure 4), or can also be defined in a standard.In the MIB that PBCH is transmitted, newly
Add information unit be used for indicate include public search space (Common Search Space, CSS) EPDCCH resource blocks
The position of collection.Certainly, existing downlink bandwidth (dl-Bandwidth) in the prior art is also included in the MIB of PBCH transmission,
Phich configures (phich-Config) and System Frame Number (systemFrameNumber).
Specifically, base station sends the relevant information of EPDCCH resource block collection to the user equipment, the EPDCCH on PBCH
The relevant information of resource block collection is used for the position for indicating EPDCCH resource block collection, and the EPDCCH resource blocks, which are concentrated, includes CSS.So
Afterwards, base station sends DCI on CSS, and the DCI includes the letter of Physical Resource Block where being used to indicate system information and beep-page message
Breath.
User equipment is received after the relevant information of the EPDCCH resource block collection from base station, according to the EPDCCH resource blocks
The position of EPDCCH resource block collection indicated by the relevant information of collection, it is determined that the CSS concentrated in the EPDCCH resource blocks position.
Then, user equipment obtains DCI on CSS, and acquisition system information and paging disappear on the Physical Resource Block indicated by DCI
Breath, so as to reside in the cell.
It should be noted that can include DMRS in PBCH is configured to the DCI that demodulation is transmitted in CSS.Certainly, should
DMRS configurations can also be pre-defined.
Detection in order to avoid lowest version user equipment to the carrier wave, it is favourable, PSS/SSS time/frequency location or
Person PBCH time/frequency location is different from existing position.So, lowest version user equipment would not detect the carrier wave.
There is no PDCCH and PCFICH (Physical Control FormatIndicator CHannel) in the carrier wave.
When highest version user equipment wants to set up RRC connections, it performs Stochastic accessing and Stochastic accessing is received in CSS
Response.After base station receives the RRC connection request message from the user equipment, the base station configures special EPDCCH resource blocks
Collect, and message is set up by RRC connections and send the relevant information of the special EPDCCH resource blocks collection to user equipment, this is special
