For example, periodic data is grouped from event flip-over type data using different resource pools or resource pool.

Embodiment two

A kind of V2X communication means, the method that UE selections send resource includes：Resource is sent based on the method choice that UE is grouped, Different transmission resources are selected to send V2X signals of communication for different groups of UE.

UE group technologies include：Geographical position based on UE and/or regional extent packet, it is different on geographical position or in not UE with regional extent belongs to different groups.Such as, V2P communication in, according to P-UE geographical position whether in track group, The position P-UE in track and the P-UE outside track respectively in different UE groups, or, the P-UE in different tracks Respectively different groups.The P-UE of difference group selects different resources to send P2V (Pedestrian to Vehicle, pedestrian user It is sent to vehicle user) signal, or, base station or roadside equipment dispatch different resources, different resources for different groups of UE It is included in the different SC-FDMA subframes of time domain selection and/or different RB is selected in frequency domain.

Or, based on random number packet, UE random generation positive integer, the positive integer value identical of generation in the range of 0~N UE is identical group, and the UE of difference group selects similar and different resource, and wherein N value sends V2X signals of communication with UE Cycle it is relevant.Such as, in V2P communications, it is assumed that the P-UE resource pool cycle is 100ms, P2V signals send the cycle For 1s, take N=10, P-UE [0,10) scope generates random positive integer m, and the offset of transmission resource is determined according to m values, 1s cycle bias internals amount sends P2V signals for selection resource in m*100ms resource pool；Or, base station or roadside equipment are The UE of difference group dispatches different resources, and different resources is included in the different SC-FDMA subframes of time domain selection and/or in frequency Domain selects different RB.

Or, indication signal is transmitted by newly defining physical channel, congestion information is indicated.Wherein, the new physical channel that defines includes control Channel and/or data transmission channel.Or further comprise, congestion information at least include occur signal congestion resource time domain scale and/ Or resource frequency domain, and/or congestion degree.V-UE random selection resource send indication signal, or using control and/or The resource competition method that data are sent, such as by signal detection, or Energy-aware.

Embodiment five

A kind of V2X communication means, the method that terminal sends V2X signals of communication includes：Determined based on resource contention or signal congestion The transmission of V2X signals of communication.Specifically include：

In the event of resource contention or signal congestion, then the transmission of V2X signals of communication is determined based on the relative distance with receiving terminal. For example, in V2P communications, if V-UE determines that the signal that P-UE is sent occurs resource contention or signal congestion occurs, sending out Resource contention or congested instruction signal and/or V2X signals are sent, P-UE is received after indication signal according to configured information determination generation There is congestion in resource contention.P-UE is based on the V2X signals or the transmitting terminal V-UE of indication signal relative distance with receiving Determine the transmission of P2V signals.Such as, judged according to threshold value, if the relative distance is less than thresholding, send V2P letters Number or selection send P2V signals with the last P2V signal identicals resource that sends, if repeatedly receiving indication signal instruction Identical resource clashes and/or occurred congestion, such as R times, R=2, and 3,4 ..., and the relative distance is less than thresholding, Then P-UE reselects resource and sends P2V signals；Otherwise, do not send or postpone to send P2V signals and/or increase the transmission cycle P2V signals are sent, or the resource that selection is differed with last transmission P2V signals sends P2V signals.Or, according to door Limit value judges, if the relative distance is more than thresholding, selection sends P2V with the last P2V signal identicals resource that sends Signal, otherwise, selection send the resource transmission P2V signals that P2V signals are differed with last.

Or, in the event of resource contention or congestion, then the geographical position based on terminal and/or regional extent determine V2X communication letters Number transmission.For example, in V2P communications, if P-UE determines occur resource contention or congestion, P-UE is based on oneself Geographical position and/or regional extent determine the transmission of P2V signals.Such as, judged based on place lane position, if P-UE exists Within the scope of track, then send P2V signals or selection and send P2V signals with the last P2V signal identicals resource that sends； Otherwise, do not send or postpone to send P2V signals and/or increase transmission cycle transmission P2V signals, or selection and last transmission The resource that P2V signals are differed sends P2V signals.Or, it is grouped according to P-UE geographical position and/or regional extent, than Such as, the distance based on from road-center, different P-UE is divided into different groups, as shown in fig. 7, Fig. 7 is according to present invention implementation The schematic diagram that the transmission of V2X signals of communication is determined based on geographical position of example, is divided into the P-UE in tri- groups of I, II, III, group I Send P2V signals or then send P2V signal identicals resource with the selection last time and send P2V signals；P-UE in group II Delay sends P2V signals and/or the increase transmission cycle sends P2V signals, or selects to send P2V signals not phase with the last time Same resource sends P2V signals；P-UE in group III does not send or postpones to send P2V signals and/or increase transmission cycle hair P2V signals, or selection is sent to send the resource transmission P2V signals that P2V signals are differed with last.Or, three differences The UE of group selects the different transmission cycles respectively and/or different delays sends P2V signals.

Or, in the event of resource contention or congestion, then the relative movement direction based on terminal determines the transmission of V2X signals of communication. For example, in V2P communications, if P-UE determines occur resource contention or congestion, P-UE is according to receiving terminal V-UE movement Direction determines that P2V signals are sent.If V-UE moving direction is forward direction, i.e. V-UE and P-UE distance are more and more nearer, Then P-UE sends P2V signals or selection and sends P2V signals with the last P2V signal identicals resource that sends；Otherwise, no Send or delay sends P2V signals and/or the increase transmission cycle sends P2V signals, or selection sends P2V letters with last Number resource differed sends P2V signals.

Or, in the event of the transmission of resource contention or congestion, then the mark ID values determination V2X signals of communication based on terminal. For example, in V2P communications, if P-UE determines occur resource contention or congestion, P-UE judges according to Termination ID value, such as Fruit ID values are odd number, then P-UE selections index sends P2V signals for the subframe of odd number, if ID values are even number, P-UE Selection index sends P2V signals for the subframe of even number.Or, ID values are based on sending cycle T selection skew for the P-UE of odd number Amount 1 sends P2V signals, and ID values are based on transmission cycle T selection offset 2 for the P-UE of even number and send P2V signals.Wherein, Offset 1 and offset 2 are the skew of the original position in Relative resource cycle, and offset 1 and offset 2.

Or, in the event of resource contention or congestion, then send V2X signals of communication based on different cycles.Confirm occur resource punching The UE of prominent or congestion changes transmission cycle transmission signal, such as increases the transmission cycle；If it is confirmed that not occurring resource contention or gathering around Plug, UE also changes the transmission cycle, such as reduces the transmission cycle.For example, in V2P communications, if P-UE confirms occur resource Conflict or congestion, then increase transmission cycle transmission P2V signals, if there are still resource contention or congestion, continuing to increase hair Send the cycle.When continuous several times do not have resource contention or congestion, then P-UE reduces the transmission cycle of P2V signals.

Or, in the event of resource contention or congestion, then V2X signals of communication are sent based on random delay, terminal by generate with Machine number X, X resource period of delay or transmission resource period postpone X transmission V2X signals of communication on the time.For example, In V2P communications, if V-UE determines occur resource contention or congestion, random number X is generated, such as generates X=3, and postpone P2V signals are sent after X=3ms.Or, such as in V2P communications, if P-UE is determined to occur resource contention or gathered around Plug, then generate random number X, such as generate X=5, and postpones to send P2V signals after 5 times of transmission resource periods.
