Description
Technical field
The present invention relates to mobile communication technology field more particularly to a kind of data transmission method for uplink, device, network side and ends
End.
Background technology
With being constantly progressive for radiotechnics, various radio traffics emerge in multitude, and radio traffic institute
The frequency spectrum resource of support is limited, is continuously increased to bandwidth demand in face of people, and traditional business correspondence master is to be used
Frequency spectrum resource shows extremely nervous situation between 300MHz~3GHz, can no longer meet the demand of future wireless system.
In future wireless system, it will extension is supported than carrier frequency higher used by forth generation (4G) communication system
Carrier frequency communicated, for example 28GHz, 45GHz etc., the potential working frequency range of 5G new RAT (NR) systems reach
100GHz.High band (>6GHz), since the decaying of electromagnetic wave is very big, it usually needs the method for wave beam forming is transmitted to be promoted
Distance, this makes the angle of coverage of wave beam become smaller.Again since the rf chain way of base station is limited, the wave beam number that can be sent simultaneously
It is limited, it needs to be sent and connect in such a way that rotation is sent to realize 360 degree or 120 degree of covering.Usual feelings
Under condition, for user equipment newly access or Idle state (UE, User Equipment), needed in access system to sweep
The mode retouched obtains the sides UE and the respective optimal transmission wave beam of network side and receives wave beam, however this beam scanning is simultaneously
Resource utilization can be reduced.
The type of service that NR is supported at present is divided into three classes, and super reliable low latency communicates (URLLC, Ultra-Reliable
And Low Latency Communications), mobile broadband (eMBB, the enhanced Mobile of enhancing
Broadband), magnanimity machine type communication (mMTC, massive Machine type communications).It is not of the same trade or business
The demand of business also differs, for example URLLC business needs reliabilities is high, and delay is low (user's delay is 0.5ms), and mMTC is then more
Emphasize that the terminal quantity for needing to support is more, little power consumption, and for reliability and delay aspect then without too high request.In order to prop up
These flexible and changeable business are held, a kind of new UE states are introduced in NR, that is, RRC_INACTIVE states, the state can be seen
Work is between UE idle states in long term evolution (LTE, Long Term Evolution) and a kind of shape among connection status
State.UE keeps battery saving mode in this state, has seldom Signalling exchange with network side, but network side still need to UE carry out with
Track, it is known which cell UE is currently located at and the optimal services of UE send also receiving node (TRP, Transmission and
Receive Point), and support that the uplink of small data volume is sent and downlink is sent.In order to realize that network side carries out UE
Tracking, UE can periodically send some reference signals.Under normal conditions, such as in LTE, upstream data is carried out, first
It needs UE first to access network, then can just proceed by some flows of upstream data transmission, delay in this case itself
Can be bigger, along with, since beam scanning can make this access delay more obvious, this obviously cannot meet NR in NR
The demand of middle business, the especially demand of URLLC business.

Time-domain resource between the corresponding downstream feedback of uplink reference signals there are correspondences.Network side is UE
Meeting while collocating uplink reference signal pass corresponding with its time-domain resource between feeding back when the resource of collocating uplink reference signal
System, UE and network side send or receive signal according to these correspondences.
Illustratively, as in Fig. 3, terminal UE side receives wave beam there are two launching beam, two and is indicated respectively with 1,2.Net
Network side gNB uses a, b, c to indicate respectively there are three wave beam, three launching beams are received.Ascending reference signal resource 1~6, and it is anti-
The correspondence for presenting resource 7~12 is that 1 correspondence 7,2 corresponds to 8 ..., and so on, 6 correspond to 12.And configure UE in resource 1,3,
Identical launching beam, configuration UE is used to use identical launching beam in resource 2,4,6 on 5.UE is with correspondence
Resource on launching beam with receive beam direction it is identical.
