Specific embodiment
Various embodiments of the present invention are described in detail below with reference to attached drawing.It, will be in addition, for ease of description
EPDCCH is described each embodiment of the invention as an example of predetermined physical down control channel.This field skill
Art personnel are appreciated that the control of predetermined physical downlink involved in present invention letter to can also develop including future communication technologies
The dedicated PDCCH of the machine-type communication being likely to occur in journey.
Referring to Fig.1, in step s101, base station determines the bandwidth of the RF block for transmitting next time.The bandwidth mark of RF block
Know the position of the RF block in whole system bandwidth.
For example, the channel quality that base station can be reported based on user equipment indicates (CQI) information, it is used for next time to determine
The bandwidth of the RF block of transmission, as shown in Figure 2.In another example base station can also randomly at some, it thinks to need to change
At the time of the bandwidth location of RF block, the bandwidth of the RF block for transmitting next time is determined.
It is understood that the amount of bandwidth of RF block is in the case of MTC UE is limited to and runs on 1.4MHz
1.4MHZ.Currently, in current or following technology development, if low cost MTC UE is limited to, to run on other bands roomy
It is small, then, the amount of bandwidth of RF block will match other amount of bandwidth.
After the bandwidth that base station has determined the RF block for transmitting next time, in step s 102, when previous transmission
EPDCCH is transmitted in (for example, subframe 1 or subframe 5 on) in Fig. 2, base station.In the Downlink Control Information (DCI) of EPDCCH carrying
Bandwidth including the RF block determined by base station next time for transmitting and the PDSCH in working as previous transmission or transmitting next time
The resource used.The bandwidth of RF block indicated by the DCI that user equipment is carried based on EPDCCH, when transmitting next time, at this
EPDCCH and/or PDSCH is received in the bandwidth of RF block.
EPDCCH and PDSCH can be multiplexed in RF block, for example, the RF block in the subframe 1 of Fig. 2.If working as previous biography
When defeated, EPDCCH and PDSCH are multiplexed RF block, then include in the DCI of EPDCCH carrying is used for down determined by base station
The bandwidth of the RF block once transmitted and the resource used in PDSCH in working as previous transmission.User equipment is held based on EPDCCH
The position PDSCH indicated by the DCI of load, receives data in corresponding resource.
Alternatively, EPDCCH can also use up the RF block in the bandwidth resources of the RF block, such as the subframe 5 of Fig. 2.In this feelings
Under shape, data will be transmitted in next subframe, this is cross-subframe scheduling.That is, being wrapped in the DCI of above-mentioned EPDCCH carrying
The bandwidth for being the RF block for being used to transmit next time determined by base station included and the money used in PDSCH in transmission next time
Source.
Then, in step s 103, when transmitting next time, EPDCCH is transmitted in the bandwidth of the RF block in base station
And/or PDSCH.For example, as shown in Figure 2, in subframe 2 or subframe 6, the bandwidth of RF block after the change is uploaded for base station
Defeated EPDCCH and PDSCH.
Referring to Fig. 2, if base station is maintained in the bandwidth of same RF block and transmits in the subsequent subframe 3,4,5 of subframe 2
EPDCCH and/or PDSCH namely base station do not change the bandwidth location of RF block, then, in one example, in subframe 2,3,4
It can not include the configuration information of the bandwidth of RF block in the DCI of the EPDCCH carrying of transmission.In another example, in subframe 2,
It also may include the configuration information of the bandwidth of RF block, certainly, the bandwidth of the RF block in the DCI for the EPDCCH carrying transmitted on 3,4
Configuration information and subframe 1 on transmit EPDCCH carrying DCI in include the configuration information of bandwidth of RF block it is identical.
It should be noted that subframe 1,2 shown in Figure 2 ..., 7 only to facilitate explanation and it is carried out
Number, in fact, Fig. 2 shows each subframe between it is not necessarily continuous.
DCI involved in the present invention can be the simple type DCI for being exclusively used in machine-type communication newly defined, in this way can be
The expense of scheduling is reduced to a certain extent.Alternatively, existing DCI in the prior art, such as format 0/1/1A/ also can be used
The bit that those are not used by can be used in existing DCI to indicate the RF block for transmitting next time in 1B/1C DCI
Bandwidth.
Since EPDCCH is not the message for needing to confirm, if user equipment does not receive the EPDCCH,
It may step-out so between base station and user equipment.Based on the consideration, base station is being received from user equipment every time
ACK/NACK signaling or receive the data from user equipment after, can all judge be in the scheduled duration after the reception
It is not no and receive the ACK/NACK signaling from the user equipment or the data from the user equipment.If in the reception
The ACK/NACK signaling from the user equipment or the number from the user equipment are not received in the scheduled duration later
According to then base station can consider its step-out between user equipment, then base station may return to last correct transmission
Radio block bandwidth on carry out subsequent transmission, for example, as shown in Figure 3 subframe 5.If this after the reception is pre-
The ACK/NACK signaling from the user equipment or the data from the user equipment are received again in timing is long, then are returned
State judgment step.
The radio block that last time correctly transmits determines in the following manner: in the bandwidth of the radio block, for uplink, base
Station receives the ACK/NACK signaling from user equipment, and/or for downlink, base station receives the number from user equipment
According to；Or if the radio block that the last time correctly transmits is not having the radio block correctly transmitted before previous transmission
The radio block that system defines.
In another example, if base station does not receive in the scheduled duration after the reception from the user
The ACK/NACK signaling of equipment or data from the user equipment, then base station can also go to the band for the block that system defines
Subsequent transmission is carried out on width, for example, subframe 5 as shown in Figure 4.The bandwidth information for the block that the system defines can be led to by base station
It crosses RRC signaling and is sent to user equipment.
Specifically, for example, base station is used by oneself receiving ACK/NACK signaling from user equipment or receive every time
After the data of family equipment, can star timer and carry out timing, the timing duration of the timer be it is above-mentioned refer to it is predetermined
Duration.For example, the timing duration of the timer can be matched with the duration of DRX timer, for example, equal to DRX timer when
Long or the duration for DRX timer multiple.If timer base station after timing expires is not received yet to use by oneself again
Any information of family equipment can then be back to one then base station can think its step-out between user equipment
Subsequent transmission is carried out in the bandwidth of the secondary radio block correctly transmitted；Or it can also go in the bandwidth of the block that system defines and carry out
Subsequent transmission.Specifically which kind of mode is subsequent biography (is carried out that is, being back in the bandwidth of the last radio block correctly transmitted using
It is defeated, still go to and carry out subsequent transmission in the bandwidth for the block that system defines), it can make an appointment between the base station and the user equipment
It is good.
It is understood that in order to increase the reliability of transmission, base station is back to the last radio block correctly transmitted
It in bandwidth or goes in the bandwidth of the block that system defines when carrying out subsequent transmission, higher convergence grade can be used
(aggregation level) is transmitted.
Ground is corresponded, in user equipment side, user equipment after receiving EPDCCH and/or PDSCH, all can every time
Judge whether receive EPDCCH and/or PDSCH again in the scheduled duration after the reception.If after the reception
The scheduled duration in do not receive EPDCCH and/or PDSCH, then user equipment can consider that it has lost between base station
Step, then user equipment may return in the bandwidth of the last radio block correctly transmitted and carry out receipt of subsequent.If institute
It states in the scheduled duration after receiving and receives EPDCCH and/or PDSCH, then return to above-mentioned judgment step.Certainly, another
In one example, user equipment, which can also be gone to, carries out receipt of subsequent in the bandwidth for the block that system defines.This depend on base station and
Making an appointment between user equipment.Similarly, user equipment side can also realize above-mentioned function by a timer.
In order to preferably make base station synchronous in reception in the transmission of EPDCCH with user equipment, just back to the last time
In the bandwidth for the radio block really transmitted or go to the EPDCCH transmitted in the bandwidth of the block that system defines can be defined on it is specific
Subframe on transmitted, such as passed perhaps on odd numbered sub-frames or in first subframe of each frame on even subframe
It is defeated.For example, for the situation transmitted in first subframe of each frame, after timer timing expires, base station and use
Family equipment needs to wait until to carry out the transmitting-receiving of EPDCCH again in the first subframe of next frame.
