Description
Technical field
The present invention relates to the transmission plan in wireless communication system, narrow band transmission is more particularly to supported
Dispatching method and device.
Background technology
At 3GPP (3rd Generation Partner Project, third generation cooperative partner program)
In RAN (Radio Access Network, wireless access network) #69 plenary session, NB-IOT
(NarrowBand Internet of Things, arrowband Internet of Things) is set up the project.NB-IOT branch
Hold 3 kinds of different operator schemes (RP-151621)：
Independent 1. (Stand-alone) operation, i.e., dispose on the frequency spectrum that GERAN systems are used.
2. protection band is operated, i.e., carried in LTE (Long Term Evolution, Long Term Evolution)
Disposed on untapped resource block in the protection band of ripple
3. with deployment on interior operation, the i.e. resource block on LTE carrier waves
Further, in NB-IOT, UE (User Equipment, user equipment) up and
It is descending all support 180kHz (kiloHertz, KHz) RF (Radio Frequency,
Radio frequency) PRB of bandwidth, i.e., one (Physical Resource Block, Physical Resource Block).
RAN1#83 meeting of 3GPP, NB-IOT systems introduce Single-tone (lists up
Frequently the concept that transmission and Multi-tone (multifrequency) are transmitted).Single-tone refers to UE up
During transmission, it can only be transmitted on one sub-carrier.Multi-tone transmission is then continued to use now
LTE (Long Term Evolution, Long Term Evolution) up SC-FDMA (Single
Carrier-Frequency Division Multiple Access, single-carrier frequency division multiple access)
Transmission means, i.e., be transmitted over the plurality of subcarriers.Single-frequency transmission a benefit be exactly, UE
Upstream radio-frequency realizes that simply, (Peak to Average Power Ratio, peak value is put down without PAPR
Equal power ratio) the problem of, and cost of implementation is low, it is possible to relatively low power consumption is kept, to improve end
The pot life of end-cell.
For traditional LTE system, ascending HARQ (Hybrid Automatic Repeat reQuest,
Hybrid automatic repeat-request)-ACK (Acknowledgement, confirm) can be in PUCCH
(Physical Uplink Control Channel, Physical Uplink Control Channel) or PUSCH
Upper transmission.And for NB-IOT, one intuitively idea be as far as possible reduction physical layer channel
Species, to reduce UE complexity.Therefore, a possible scheme is HARQ-ACK in physics
Layer data channel, i.e., will not design physical layer control channel specifically for HARQ-ACK.
The content of the invention
In 3GPP RAN1#83Ad_hoc meetings, for based on Single-tone and Multi-tone
Uplink, respectively define and take the different resource units (Resource Unit) of millisecond number.
For Single-tone, the corresponding PUSCH (Physical of 15kHz subcarrier spacings
Uplink Shared Channel, Physical Uplink Shared Channel) resource units time domain take
8ms (millisecond), the corresponding PUSCH resource units of 3.75kHz subcarrier spacings take 32ms in time domain.
For Multi-tone, corresponding resource units are in time domain when PUSCH takes 3 subcarriers
4ms is taken, corresponding resource units take 2ms in time domain when PUSCH takes 6 subcarriers,
Corresponding resource units take 1ms in time domain when PUSCH takes 12 subcarriers.
Inventor is had found by studying, based on resource units defined above, in Single-tone,
And under subcarrier spacing is 3.75kHz scene, a uplink at least needs to take 32ms.
And if by the UL of DL-SCH (Downlink Shared Channel, DSCH Downlink Shared Channel)
HARQ-ACK is put into PUSCH transmission, it is likely that occur that PUSCH corresponding UL Grant (are awarded
Give) DL Grant (authorizing) corresponding earlier than DL-SCH, under this scene, base station is in scheduling PUSCH
Shi Wufa knows whether the PUSCH needs to be embedded in UL HARQ-ACK transmission, also can not just notify
UE carries out the associative operations such as rate-matched to improve spectrum efficiency.A kind of intuitively scheme is PDSCH
Corresponding UL HARQ-ACK wait the PUSCH transmission of next UL Grant scheduling, but
Because the time window that up-downgoing is dispatched under Single-tone is mismatched, by taking 3.75kHz as an example,
Descending scheduling window is 1ms, and upper behavior 32ms, and the above method can bring downlink data transmission pair
The a large amount of delays for the uplink feedback answered.
