Below in conjunction with specific embodiment, technical scheme is described and illustrates.
Preferred embodiment one
The SCI form of advertised information, has two ways：
Mode one：Using 3GPP agreement R12 version definition.
The SCI form of advertised information is still using fixed in 3GPP (3rd Generation Partnership Project) agreement R12 versionJustice.The certain combinations of values of the particular value or several domain that define one of domain here represents that advertised information is true, such as ' ModulationAnd coding scheme (MCS) ' domain uses one of retention (29,30,31), represents that right of way signal is true, or uses ' TimeThe retention in resource pattern ' domain, such as NTRPRetention 0 (N when=7TRP, the bit of Time resource pattern instructionLength), represent that right of way signal is true, that is, represent the pre- resource taking the n-th communication cycle of high priority UE, low priority UEResource selection should be carried out using the corresponding strategy of its priority, such as abandon taking resource, or change resource occupation probability or changeResource selection scope in resource pool etc..
One example：' Modulation and coding scheme (MCS) ' domain value 29 represents that right of way signal is true, noticeThe time domain of other domains of signal SCI instruction and frequency domain resource represent that these resources will be taken by high priority UE in the n-th communication cycle,Low priority UE can not reuse.
Mode two：Define new SCI form.
Define new SCI form, including the combination of in following domain or several：
Pre- occupancy identification field, represents whether high priority UE takies resource in the n-th communication cycle.
Sending probability domain, represents the sending probability of other priority UE.Can be multiple values, indicate respectively different priorities UESending probability.
Frequency domain resource instructions field (FR), represents frequency domain resource region or only selectable frequency domain that other priority UE should avoidResource area.
Time-domain resource instructions field (TR), represents time-domain resource region or only selectable time domain that other priority UE should avoidResource area.
As shown in figure 4, an example is such as：Pre- occupancy is designated 1, and sending probability is p1, p2.Frequency domain resource indicates FR, tableShow that other priority UE only can select in the resource area of FR instruction.Time-domain resource TR, represents that other priority UE only may be usedSelect in the time domain region of TR instruction.
Above SCI content representation, the n-th communication cycle, high priority UE takies resource in advance, and other priority UE are only permissibleSelect resource in the resource area of FR and TR instruction, and, the UE sending probability of 2a priority is p1,2b is preferentialThe sending probability of level UE is p2.
Preferred embodiment two
Position in PSCCH resource pool for the specific SCI resource of broadcasting announcements information, can be pre-configured for user equipment, or byCentroid configures, or sets up configuration signal to indicate by resource pool configuration signal or communication user group.
Example one, the specific SCI resource of advertised information is first SCI resource on PSCCH resource pool, wherein, SCI formDefined in preferred embodiment one.The resource location of sequence number 1 in first SCI resource location in example, such as Fig. 5：
Example two, the specific PSCCH resource sending for advertised information is not limited to first SCI on PSCCH resource poolResource, can define first SCI resource and penultimate SCI resource on PSCCH resource pool and be used for broadcasting announcements information,Or definition resource sequence number N meets the part PSCCH resource that N mod Nt is 2m or 2m+1, wherein Nt is that PSCCH providesThe subframe number in source pond, m is the integer more than or equal to zero.SCI resource as the sequence number 1 and 15 in Fig. 6.
Example three, the specific PSCCH resource of the SCI sending for advertised information, the special PSCCH resource of definable.AsOne end of the low frequency or high frequency that define PSCCH resource pool retains the transmission that continuous running time-frequency resource is used for advertised information.In Fig. 7Advertised information specific PSCCH resource area.Wherein send resource can select in this specific PSCCH resource area one orMultiple.
Alternatively, high priority UE takies the resource in the n-th cycle in advance if desired for broadcasting announcements information, then first defined aboveOne or more transmissions as advertised information are selected in advertised information SCI resource location.But if current period also has data toSend, that is, also need to send the SCI of data dispatch, then need to ensure advertised information SCI of selection with data dispatch SCI not in phaseSame subframe.If both have selected identical subframe position, consider to reselect data dispatch SCI resource, until at least 1Available advertised information SCI of individual selection not with data dispatch SCI in identical subframe.
Preferred embodiment three
Low priority UE takies advertised information SCI ad-hoc location in advance in resource and goes to receive and parse through advertised information, if be properly received,Obtain resource and take advertised information in advance, then the resource process side according to pre-configured resource processing mode or the instruction of advertised information SCIFormula carries out respective resources occupancy process.
If resource location shared by low priority UE current communication cycle sending signal exists with receiving advertised information SCI ad-hoc locationIdentical subframe, for single transmitting-receiving receiver user equipment, preferentially ensures to send the data of oneself, does not only send at oneselfAdvertised information and other signals are received on the subframe of data.
Wherein, pre-configured resource processing mode, is the initially cured configuration of UE equipment, or has obtained money through configuration processSource processes relevant configuration etc..During as there is the pre- Seize ACK message of high priority UE resource, pre-configured is corresponding with UE priority levelSending probability, or predefined selectable scope of resource etc..
The resource processing mode of advertised information SCI instruction, is the SCI content that low priority UE passes through that parsing carries advertised information,Obtain its follow-up sending probability taking resource, selectable scope of resource etc., then according to instruction carries out respective handling.
Alternatively, low priority UE is according to acquired or pre-configured resource occupation relevant configured parameter, in selectable resourceOn, participate in selecting and sending data with corresponding probit.
One example：Pre-configured low priority UE, after the resource occupation signal receiving high priority UE transmission, abandons n-thThe resource selection of communication cycle takies.
Another example, low priority UE, parse advertised information SCI, wherein in SCI parameter, sending probability is p1, can frequency-selectingDomain resource is FR, and optional time-domain resource is TR, then this UE is in the n-th communication cycle, with Probability p 1, in selectable resourceUpper autonomous selection resource carries out data is activation.
