Technical field
The present invention relates to mobile communication technology fields, and in particular to a kind of resource allocation method, resource selection method, information
Method of reseptance and equipment.
Background technique
In existing LTE (Long Term Evolution, long term evolution)-V2X (Vehicle-to-Everything, vehicle
Networking) in, time-domain resource granularity is subframe, and length 1ms, the subcarrier spacing of frequency domain resource is 15kHz;Existing LTE V2X
The minimum-time lag of support is 20ms.
In LTE-V2X, the Basic Design of D2D (Device to Device, device-to-device) frame structure, TTI are continued to use
(transmission time interval) length is 1ms, and a TTI includes two time slots, and first symbol of subframe is used for bearer service data,
Receiving end carries out AGC (Automatic Gain Control, automatic growth control) adjustment on the symbol.Subframe last
A symbol is used as GP (Guard Period, protection interval), and GP carries out RE (Resource using the method for puncture
Element, resource element) mapping.
In PC5V2X signal, dedicated AGC measured zone is not introduced, and wherein the measurement of AGC passes through first of subframe
Symbol carries out, and such way has following features: not introducing additional mechanism in a standard, is one and realizes the method solved;
The resource overhead of fixed AGC is not needed, an OFDM (Orthogonal is only lost when D2D generating state is converted
Frequency Division Multiplexing, orthogonal frequency division multiplexing) symbol.
Due to the higher relative moving speed of car networking, carrier frequency can arrive 6GHz, so the correlation time for receiving signal shortens,
The pilot tone time domain interval of channel needs to shorten.Further, additional frequency shift (FS) is introduced in synchronizing process, therefore,
Under each subframe of PC5V2X, four frequency pilot signs are needed, as shown in figure 1 PSCCH (the Pysical Sidelink of PC5V2X
Control Channel, physical bypass control channel) and PSSCH (Pysical Sidelink Share Channel, physics
Bypass shared channel) shown in the frame structure of channel, specific frequency pilot sign DMRS (Demodulation Reference
Signal, demodulation reference mark) position be (2,5,8,11).
In PC5V2X system, since covering radius target is only 300 meters, LTE routine CP (Cyclic is supported
Prefix, cyclic prefix) length, i.e. routine CP length, system covering can be met and required.
For PSBCH (Pysical Sidelink Broadcast Channel, physical bypass broadcast channel),
The frame structure of PSBCH channel occupies as (4,6,9), the frame knot as shown in Fig. 2, the DMRS number of frequency pilot sign occupied is 3
It further include PSSS (Primary Sidelink Synchronization Signal, main bypass synchronization signal) and SSSS in structure
(Secondary Sidelink Synchronization Signal, auxiliary bypass synchronization signal).
It wherein, include altogether 3 class physical channels in PC5V2X system, PSSCH channel is the channel for carrying data,
Coding, rate-matched, the physical layer process mechanism such as intertexture are identical as D2D;PSCCH is the channel for carrying control information, SA
(Scheduling Assignment, dispatch), coding, rate-matched, the physical layer process mechanism such as intertexture are identical as D2D;
PSBCH channel is used for synchronously control and adjustment, increases 8 bits as reserving compared to D2D, leads to avoid head and the tail symbol is destroyed
The decoding error problem of cause.Wherein the generation of PSSS is identical as D2D, and SSSS uses the SS sequence of LTE subframe 5.
The configuration of the resource pool of SA and DATA (data) includes two kinds of adjacent band and non-adjacent band in the prior art.SA be associated with DATA
Sent in the adjacent band of the same subframe, SA be associated with DATA resource and sent in same subframe, and the two is adjacent on frequency domain.
SA be associated with DATA and sent in the non-adjacent band of the same subframe, SA and DATA use separate physical resource, and the two is on frequency domain
Not overlapping, from user level, SA is also frequency division multiplexing with DATA is associated with, and the DATA resource that SA is indicated with it is in same son
Frame.
In the configuration of resource pool, respectively the transmission mode in adjacent band and non-adjacent band defines the method that resource pool configures,
It is wherein as shown in Figure 3a for the resource pool configuration method that defines of transmission mode in adjacent band, for the money that defines of transmission mode in non-adjacent band
Source pond configuration method is as shown in Figure 3b.
Wherein, include: that can not support minimum 1ms or less delay requirement the shortcomings that existing LTE-V2X, do not support single carrier
The message transmission rate of every sub-frame transmission 31704bit or more, the correlated performance in LTE-V2X are unable to satisfy low time delay, higher
The demand of reliability and message transmission rate.
Meanwhile in LTE-V2X, the time-domain resource and frequency domain resource of SA and DATA use identical granularity.But if branch
It has held different numerology (time-domain resource granularity and frequency domain resource subcarrier spacing), reception UE (User Equipment,
User equipment) it needs to carry out blind examination to SA based on different numerology, it will it is obviously improved UE and the blind examination ability of SA is wanted
It asks.
On the other hand, for backwards compatibility the considerations of, more in support if NR (New Radio, the newly eat dishes without rice or wine) technology of introducing
The NRV2X UE of kind of numerology and only the Release14V2X UE of support 1msTTI length are the shared resource pond the case where
Under, resource exclusion can not be carried out since Release14 can not decode the SA of other numerology, to increase resource collision
Probability.
