Description
The application is the divisional application of following original application:
-- the applying date of original application: on February 01st, 2016
-- the application number of original application: 201610070382.4
-- the invention and created name of original application: dispatching method and device in a kind of wireless communication
Technical field
The present invention relates to the transmission plan in wireless communication system, more particularly to the dispatching method for supporting narrow band transmission and
Device.
Background technique
In 3GPP (3rd Generation Partner Project, third generation cooperative partner program) RAN (Radio
Access Network, wireless access network) in #69 plenary session, NB-IOT (NarrowBand Internet of Things, it is narrow
Band Internet of Things) it is set up the project.NB-IOT supports 3 kinds of different operation modes (RP-151621):
1. independent (Stand-alone) operation, i.e., dispose on the frequency spectrum that GERAN system uses.
2. protection band operates, i.e., in the protection band of LTE (Long Term Evolution, long term evolution) carrier wave not
It is disposed on the resource block used
3. being disposed on the resource block on LTE carrier wave with interior operation
Further, in NB-IOT, UE (User Equipment, user equipment) supports 180kHz in uplink and downlink
RF (Radio Frequency, the radio frequency) bandwidth of (kiloHertz, kHz), i.e. a PRB (Physical Resource
Block, Physical Resource Block).
RAN1#83 meeting of 3GPP, NB-IOT system uplink introduce Single-tone (single-frequency) transmission and
The concept of Multi-tone (multifrequency) transmission.Single-tone refer to UE uplink send when, only can on one sub-carrier into
Row transmission.Present LTE (Long Term Evolution, long term evolution) uplink SC-FDMA is then continued to use in Multi-tone transmission
The transmission mode of (Single Carrier-Frequency Division Multiple Access, single-carrier frequency division multiple access),
Transmitted over the plurality of subcarriers.One benefit of single-frequency transmission is exactly that UE upstream radio-frequency is realized simply, without PAPR
The problem of (Peak to Average Power Ratio, papr), and cost of implementation is low, and can keep compared with
Low power consumption, to improve the pot life of end cell.
For traditional LTE system, (Hybrid Automatic Repeat reQuest mixes automatic weight to ascending HARQ
Pass request)-ACK (Acknowledgement, confirmation) can PUCCH (Physical Uplink Control Channel,
Physical Uplink Control Channel) or PUSCH on transmit.And for NB-IOT, an intuitive idea is to reduce object as far as possible
The type of layer channel is managed, to reduce the complexity of UE.Therefore, a possible scheme is HARQ-ACK in physical layer data channel
Upper transmission will not design physical layer control channel specifically for HARQ-ACK.
Summary of the invention
In 3GPP RAN1#83 Ad_hoc meeting, for the uplink based on Single-tone and Multi-tone,
It respectively defines and occupies the different resource units (Resource Unit) of millisecond number.For Single-tone, 15kHz
The corresponding PUSCH in carrier wave interval (Physical Uplink Shared Channel, Physical Uplink Shared Channel) resource units
8ms (millisecond) is occupied in time domain, the corresponding PUSCH resource units of 3.75kHz subcarrier spacing occupy 32ms in time domain.For
For Multi-tone, corresponding resource units occupy 4ms in time domain when PUSCH occupies 3 subcarriers, and PUSCH occupies 6 sons
Corresponding resource units corresponding resource units in time domain occupancy 2ms, PUSCH 12 subcarriers of occupancy are accounted in time domain when carrier wave
Use 1ms.
Inventors discovered through research that resource units based on above-mentioned definition, in Single-tone, and subcarrier spacing
Be 3.75kHz scene under, a uplink at least needs to occupy 32ms.And if by DL-SCH (Downlink Shared
Channel, DSCH Downlink Shared Channel) UL HARQ-ACK be put into PUSCH transmission, it is likely that will appear the corresponding UL of PUSCH
Grant (authorizing) DL Grant (authorizing) corresponding earlier than DL-SCH, in this scenario, base station can not be known when dispatching PUSCH
Whether the road PUSCH needs to be embedded in the transmission of UL HARQ-ACK, also can not just notify UE carry out the relevant operations such as rate-matched with
Improve spectrum efficiency.A kind of intuitive scheme is that the corresponding UL HARQ-ACK of PDSCH waits next UL Grant to dispatch
PUSCH transmission, however since the time window that uplink and downlink is dispatched under Single-tone mismatches, by taking 3.75kHz as an example, downlink
Scheduling window is 1ms, and upper behavior 32ms, and the above method can bring largely prolonging for the corresponding uplink feedback of downlink data transmission
Late.
