Description
Technical field
The present invention relates to the transmission plans of the wireless signal in wireless communication system, more particularly to configurable subcarrier
The method and apparatus of the wireless transmission at interval.
Background technique
Existing LTE (Long-term Evolution, long term evolution) and LTE-A (Long Term Evolution
Advanced, the long term evolution of enhancing) in system, the subcarrier spacing (Subcarrier Spacing) of each down channel is equal
It is consistent, and is equal to 15kHz.In Release-14, communicated for IoT (Internet of Things, Internet of Things), it is special
Be not NB (Narrowband, narrowband)-IoT equipment, propose uplink use the subcarrier spacing of 3.75kHz (kHz) with
Reduce the complexity and cost of terminal device.
The wireless access technology (NR, New Radio access technologies) of a new generation is at present by 3GPP
(3rd Generation Partner Project, third generation cooperative partner program) project verification.Wherein, three kinds of scenes are in TR
It is defined in (Technical Report) 38.913, is respectively:
- eMBB (enhanced Mobile Broadband, the mobile broadband of enhancing)
- mMTC (massive Machine Type Communications, a large amount of machine type communication)
(Ultra-Reliable and Low Latency Communications and low prolongs at ultrahigh reliability-URLLC

In existing LTE and lte-a system, all DM-RS (Demodulation based on data channel transmission
Reference Signal, demodulated reference signal) sequence generates, and is mapped to a PRB (Physical Resource
Block, Physical Resource Block) centering RE (Resource Element, resource unit) mode, be all based on fixed son and carry
Wave spacing design.UE only needs to obtain the AP (Antenna Port, antenna port), the number of plies (Number of of base station configuration
Layer), SCI (Scrambling Identity, scrambling code identification) and other relevant informations, so that it may know DM-RS in a PRB
The position RE occupied by centering, and generate the reference signal sequence of DM-RS.When UE and base station support a variety of subcarrier spacings
When, the corresponding different DM-RS generating modes and mapping mode for different sub-carrier interval are also required to be defined.
A kind of simple mode configures different DM-RS generating mode and mapping side aiming at different sub-carrier interval
Formula.However, the above method there is a problem of two it is significant.First problem is that the mapping mode of DM-RS is predefined at present
, the AP number and the number of plies that base station only needs dynamic instruction to configure, if subcarrier spacing can be flexible according to application scenarios and demand
Variation, if predefining the mapping mode and sequence generating mode of a variety of DM-RS, system realization will be complex.Second is asked
