Description

A kind of method and device that vehicle communicates extraneous V2X
Technical field
The present invention relates to fields of communication technology, specifically, the present invention relates to a kind of vehicles to the extraneous V2X methods communicated and Device.
Background technology
Device-to-device (full name in English：Device to Device, english abbreviation：D2D) communication technology relies on it in public affairs Huge potential value in security fields and the normal domestic communications field altogether, realizes standardization in 3 gpp.It is marked in 3GPP In standard, the referred to as bypass (Sidelike) of equipment to the direct communication link between setting is similar with uplink with downlink, There is also control channels and data channel in bypass, the former is known as Bypass Control channel (full name in English：Physical Sidelink Control CHannel, english abbreviation：PSCCH), the latter is known as bypass data channel (full name in English： Physical Sidelink Shared CHannel, english abbreviation：PSSCH).PSCCH is used to indicate the time-frequency of PSSCH transmission The information such as domain resource location, modulation coding scheme and the targeted reception Target ids of PSSCH, PSSCH is for carrying data.
Because the D2D of 3GPP Plays is communicated mainly for low speed terminal, and to time delay sensitivity and is received reliable Property require lower business, it is therefore, wide based on current D2D so the D2D functions of having realized are also far from user demand is met Broadcast communication mechanism, 3GPP is furthermore achieved support high-speed equipment between, between high-speed equipment and low-speed device and high-speed equipment The communication of direct low time delay high reliability between static equipment, i.e. vehicle are to extraneous (full name in English：Vehicle to Vehicle/Perdestrian/Infrastructure/Network, english abbreviation：V2X), the standardization of partial function. Therefore, the bypass communication at present in 3GPP includes the two different patterns of D2D and V2X.
Since V2X communication services have natural periodicity, for the terminal of each participation V2X communications, it is possible to Generate multiple periodic business.Therefore, semi-static resource allocation mechanism is introduced in current standardized V2X systems (full name in English：Semi-Persistent Scheduling, english abbreviation：SPS) mechanism.According to this mechanism, communicated in V2X In the resource distribution mode of middle eNB controls (Mode 3), eNB can be the UE configurations one for carrying out V2X communications by rrc layer signaling Or multiple SPS configurations, when UE generates the business for meeting a certain SPS configurations, eNB can be sent corresponding by down control channel Downlink Control Information (full name in English：Downlink Control Information, english abbreviation：DCI corresponding SPS) is triggered Configuration；When UE no longer generates the business, eNB can send corresponding DCI and discharge SPS configurations corresponding with the business.Due to Support that the DCI format of SPS activation and release is different from current existing DCI format, if the DCI format and existing DCI format When being mapped to the specific downlink search space identical UE, the increase of UE down control channel blind examination numbers will be caused.
In addition to this, congestion control mechanism is also introduced in V2X, UE will adjust maximum transmission power, modulating-coding strategy (full name in English：Modulation and Coding Scheme, english abbreviation：MCS), maximum resource occupation proportion, maximum pass Defeated number etc., to adapt to current Congestion Level SPCC.Since UE needs that open Loop Power control is supported to connect eNB uplinks to reduce simultaneously The interference of receipts, so as to cause can not currently meet congestion control and uplink interference control simultaneously.
For supporting the UE of V2X communications, have the ability to receive Global Navigation Satellite System (full name in English：Global Navigation Satellite System, english abbreviation：GNSS) signal, therefore introduce and be based in V2X communication systems The synchronization mechanism of GNSS.According to this mechanism, GNSS signal can be received in the covering of cellular network cell and accurately UE and it GNSS synchronizing signals UE can be received outside cellular network cell and accurately can send bypass synchronizing signal (english abbreviation：SLSS) and bypass broadcast channel (english abbreviation：PSBCH), the possible difference of the PSBCH contents of the two, when upper State two kinds of UE or with above two UE be with reference to synchronisation source UE identical running time-frequency resource send PSBCH when, between each other will Interference is generated, PSBCH detection failures are caused.
By analyzing above, it can be seen that introduce new Resource Scheduling Mechanism, congestion control in current V2X communication systems Making mechanism and new synchronization mechanism, above-mentioned three kinds of new mechanisms improve the performance of V2X systems, while problems have also been introduced, For these problems, at present still without ideal technical solution.
