As described above, in current 3GPP standardization efforts, it has been proposed that for the power efficiency of remote equipment
Research.In order to which the trunking to adjacent service (ProSe) carries out selection and gravity treatment, remote equipment needed in each discovery period
It searches for candidate trunking and measures SD-RSRP in each measurement period.In traditional LTE system, for by being used for
The remote equipment of the upper-layer configured of operation of relays, when the RSRP of serving cell or PCell measure be less than threshold value, remote equipment in order to
Candidate relay equipment is searched in selection or gravity treatment in each discovery period.It is set if remote equipment has selectable side link trunking
Standby, then remote equipment, which finds that the SD-RSRP that selected trunking is measured in the period is primary and assesses it at every four, is
It is no to meet relay selection criterion (being defined on 3GPP TS 36.331V14.0.0 (2016-09)).During remote equipment is often used in frequency
After the T of equipmentmeasure,ProSe_Relay_Intra(be detected and measured according to measurement rules) measures candidate trunking
SD-RSRP, as specified in 3GPP TS 36.133V14.1.0 (2016-09), Tmeasure,ProSe_Relay_IntraValue be equal to
Four.It is measured and is operated by above-mentioned SD-RSRP, the ProSe trunkings that remote equipment can select or gravity treatment is suitable.
However for FeD2D, wearable device is usually carried with smart phone together.Smart phone can be used as relaying
Equipment is for assisting wearable device (namely remote equipment).Since remote equipment and trunking often move together.Energy
The selection result of enough reasonable assumption trunkings generally remains constant.Therefore, for candidate relay equipment it is frequent search and
It measures not usually necessary.In this case, the search in the prior art for candidate relay equipment is with SD-RSRP's
It is excessive to measure operation, causes the power wastage of remote equipment.
Therefore, it is necessary to the energy saving of a kind of selection of effective ProSe trunkings for remote equipment and gravity treatment
Scheme.According to the pairs of mobility of wearable device, the search of candidate relay equipment and measurement period can be extended to subtract
It is small that the search of candidate relay equipment and the measurement of SD-RSRP are operated, to save the power consumption of remote equipment.
In order to solve these and other possible potential problems at least partly, in accordance with an embodiment of the present disclosure, allow remote
The period that journey equipment adjusts the search cycle of its candidate relay equipment and SD-RSRP is measured.During once remote equipment has selected
After equipment, begins the evaluation at and whether meet cycle stretch-out condition.If the condition is satisfied, remote equipment extends its candidate relay
The period that the search cycle of equipment and SD-RSRP are measured.According to this method, remote equipment can be in response to searching in candidate
After equipment, the SD-RSRP of the candidate relay equipment is measured with a measurement period.Based on the measurement to SD-RSRP, from candidate
After selection trunking in equipment to match.Determine whether the SD-RSRP of selected trunking meets cycle stretch-out condition.
Meet cycle stretch-out condition in response to the SD-RSRP of selected trunking, extends for measuring selected trunking
With the measurement period of the SD-RSRP of other trunkings in candidate relay equipment.
In this manner it is possible to extend remote equipment for searching for candidate relay equipment and measuring the period of its SD-RSRP, subtract
Few that the search of candidate relay equipment and the measurement of SD-RSRP are operated, the power to provide remote equipment saves gain.Below

The SD-RSRP of candidate trunking is measured with a measurement period.According to the measurement result to SD-RSRP, from all candidates
Trunking in selection one trunking matched.Such as in Fig. 1, the selection of remote equipment 110 and trunking 120
It is matched.After being paired, the selection of remote equipment 110 has the characteristics that pairing is mobile with trunking 120, activates for week
Phase extended detection determines whether the SD-RSRP of this selected trunking 120 meets cycle stretch-out condition.Herein
In the process, the SD-RSRP of candidate trunking is still measured with original measurement period.Once it is determined that the selected relaying is set
Standby 120 SD-RSRP meets cycle stretch-out condition, then extends and set for measuring selected trunking 120 and candidate relay
The measurement period of the SD-RSRP of other trunkings in standby.Embodiment in this respect will be described in detail later.
The principle and specific embodiment of the disclosure are described in detail below in conjunction with Fig. 2 to Fig. 5.First refering to fig. 2,
It illustrates the flow charts according to the exemplary communication methods 200 of some embodiments of the disclosure.It is appreciated that method 200 can be with
Such as implement at remote equipment 110 as shown in Figure 1.For convenience of description, method 200 is described with reference to Fig. 1.
In one embodiment of the disclosure, remote equipment 110 scans for the trunking in coverage area, with hair
Now corresponding trunking and matched therewith.Herein, the trunking in coverage area is set referred to as candidate relaying
It is standby.As shown, 205, when remote equipment 110 searches candidate relay equipment, measure candidate's with a measurement period
Trunking.
210, according to the measurement result of the SD-RSRP by measuring the candidate trunking obtained, from candidate relaying
A trunking 120 is selected in equipment, to be matched with the trunking 120.It should be noted that above-mentioned measurement period
Length can be for remote equipment 110 be pre-configured, can also be from the network equipment associated with the remote equipment 110 100
It receives.
At 215, determine whether the SD-RSRP of selected trunking meets cycle stretch-out condition.If at 215
Judgement result be yes, i.e., the SD-RSRP of selected trunking meets cycle stretch-out condition, then at 220, to being used to survey
The measurement period of the SD-RSRP and other trunkings in candidate relay equipment that measure selected trunking are extended.
If the judgement result at 215 is no, i.e., the SD-RSRP of selected trunking is unsatisfactory for cycle stretch-out condition, then not
Extend the measurement period of the SD-RSRP and other trunkings in candidate relay equipment of selected trunking.In Fig. 2
In, if the judgement result at 215 is no, process can be returned at 205, to carry out the measurement and determination of a new round
Process.It should be noted that according to some embodiments of the disclosure, process can be returned at 205.According to its of the disclosure
His embodiment, process can also terminate herein.
Referring again to 215 in Fig. 2 according to one embodiment of the disclosure, after being paired, still with initial measurement
The SD-RSRP of the selected trunking of period measurement 120.At the same time, remote equipment 110 is also surveyed with initial measurement period
Measure the SD-RSRP of other trunkings in candidate trunking.Then, remote equipment 110 is to selected trunking
120 SD-RSRP is compared with the SD-RSRP of other trunkings in candidate relay equipment.If obtained from measurement result
Go out, the SD-RSRP of selected trunking 120 is persistently higher than in other in candidate trunking within a predetermined period of time
After the SD-RSRP of equipment, then meet cycle stretch-out condition.In addition, according to one embodiment of the disclosure, after being paired, still
The SD-RSRP of selected trunking 120 is so measured with initial measurement period.It is selected if obtained from measurement result
Trunking 120 SD-RSRP within a predetermined period of time persistently be higher than previously given threshold value, then also meet cycle stretch-out item
Part.It should be noted that the threshold value of above-mentioned previously given SD-RSRP can be pre-configured for remote equipment 110, it can also
It is received from the network equipment (such as base station 100 in Fig. 1) associated with the remote equipment 110.
Fig. 3 shows the schematic diagram of the progress cycle stretch-out according to some embodiments of the disclosure.As shown in figure 3,310
In.Either before or after remote equipment selects trunking, remote equipment always sets relaying with measurement period T1
It is standby to carry out SD-RPSP measurements, and the length T1 of measurement period does not change always in the subsequent time.And in 320,
Before remote equipment selects trunking, remote equipment carries out SD-RPSP measurements with measurement period T1 to trunking.Long-range
After equipment selects trunking, remote equipment temporarily carries out SD-RPSP several times to trunking with measurement period T1 and measures.One
Denier remote equipment determines that cycle stretch-out condition is satisfied, i.e., the SD- for the selected trunking having been described in above
RSRP is persistently higher than in the SD-RSRP or selected of other trunkings in candidate trunking within a predetermined period of time
Persistently it is higher than previously given threshold value within a predetermined period of time after the SD-RSRP of equipment, then executes cycle stretch-out.Such as in 320
It shows, measurement period is extended for T2 by T1.Remote equipment can also repeatedly be made whether to meet cycle stretch-out condition really
It is fixed.For example, remote equipment carries out SD-RPSP several times to trunking and measures now with the measurement period after extension, i.e. T2.
Once remote equipment determines that cycle stretch-out condition is satisfied, then cycle stretch-out is executed again.As shown in 320, week is measured
Phase is extended for T3 by T2.By this method, once cycle stretch-out condition is satisfied, remote equipment automatically regulates it and is used for candidate eventually
The period that end equipment is searched for and SD-RSRP is measured.Herein it should be noted that although above for the candidate relaying of measurement
The measurement period of the SD-RSRP of equipment carries out the volume explanation of cycle stretch-out.However, the period shown in Fig. 3 can also be regarded as using
In the discovery period of candidate trunking search.The cycle stretch-out scheme that the disclosure is proposed can be used in above two week
Phase extends above.In fact, the measurement period for being used to search for the search cycle of candidate trunking and being measured for SD-RSRP
Cycle length between relationship be fixed, can be conditioned together.Such as in traditional LTE, remote equipment is each
It was found that periodic searches candidate relay equipment is primary and finds the SD-RSRP of the selected trunking of period measurement at every four
Once.In other words, if the cycle T 1 being shown in FIG. 3 is the candidate relay equipment search cycle, T1 is equivalent to a discovery
Period.If the cycle T 1 being shown in FIG. 3 is the measurement period of SD-RSRP, T1 is equivalent to four discovery periods.
Turn again to the 215 of Fig. 2.What needs to be explained here is that the period mentioned above can gradually be extended.Example
Such as when extension condition meets, the period of remote equipment is changed into twice of original value by original value.Later for example when condition into
When one step is satisfied, become the original value to quadruple from twice of original value.
According to one embodiment of the disclosure, measured for the search cycle of selected trunking 120 and SD-RSRP
Period can be different from search cycle and SD-RSRP measurement periods for other trunkings in candidate relay equipment.One
Denier extends condition and is satisfied, and remote equipment can be come with the period for being longer than the cycle length of selected trunking in candidate
SD-RSRP measurement periods are carried out after other trunkings in equipment, even by will be used in candidate relay equipment
The extension in the period of other trunkings inhibits to set other relayings in candidate relay equipment to infinitely great mode
Standby search and measurement.
According to one embodiment of the disclosure, to the SD-RSRP and candidate relay for measuring selected trunking
The measurement period of other trunkings in equipment extend and can be realized by two methods.Due to being used for searching for candidate
Trunking search cycle and for SD-RSRP measure measurement period cycle length between relationship be it is fixed,
The extension of measurement period can be realized by extending the length in the discovery period for searching for candidate relay equipment, can also increase
Big measurement period and the multiple between the discovery period.For example, remote equipment is primary in each discovery periodic searches trunking,
The SD-RSRP of every four discoveries period measurement trunking is primary.Assuming that the search cycle, there is the first length and measurement period to have
There is the second length, then the second length is equal to four times of the first length.Therefore, extending the period can be by increasing the first length or increasing
Multiple between big second length and the first length is realized.
320 could be aware that the period can continuously be extended in as mentioned before and combination Fig. 3.Such as 320
In, cycle length is extended for T2.If after this according to aforementioned activities, i.e., to measure institute through extended measurement period
The SD-RSRP of the SD-RSRP of the trunking of selection and determining selected trunking continues to meet cycle stretch-out condition,
Then cycle length will be extended for T3.If at this moment determining that the SD-RSRP of selected trunking no longer meets cycle stretch-out
Condition then executes fallback action.I.e. again with initial value, i.e., the search of the progress trunking of cycle T 1 in figure 3 and SD-
RSRP is measured.According to one embodiment of the disclosure, the SD-RSRP of selected trunking no longer meets cycle stretch-out condition
The case where can be the SD-RPSP of this selected trunking be no longer that highest in all candidate relay equipment
, or be this selected trunking SD-RPSP value already below previously given threshold value.
It is stopped suddenly it should be noted that the fallback action is likely to occur in such as trunking, such as works as relaying
Equipment is smart phone, and in the case that the unexpected electricity of smart phone exhausts.The fallback action, which can also be happened to receive, to be come
From the external world, such as the instruction with the network equipment of the associate remote devices or user, the connection with the remote equipment is cut
In the case of shifting to another trunking.Once retracting, then the search to trunking and SD- are carried out with initial value again
RSRP is measured.
It should be pointed out that the configuration of parameter related with cycle stretch-out, such as the condition for cycle stretch-out and rollback
Threshold value and proposition cycle stretch-out process activation and deactivation, can be implemented by following two modes, you can with long-range
It is pre-configured in equipment, such as is added to side chain road and is pre-configured (SL-Preconfig), can be used in the covering model of the network equipment
Remote equipment except enclosing；It can also be set by RRC signaling by the associated network equipment, such as eNB.Therefore, this is long-range
The parameter of equipment can be adjusted neatly.
Fig. 4 shows the flow chart of the exemplary communication method 400 according to the other embodiment of the disclosure.Fig. 5 show by
According to the schematic diagram of the progress cycle stretch-out of the exemplary communication method 400 of the other embodiment according to the disclosure of Fig. 4.With reference to
Fig. 4 and Fig. 5 illustrates the exemplary method of one embodiment according to the disclosure.Some being described in detail above are thin
Section, repeats no more here.
Start execution method 400, searches for candidate trunking.At 405, with cycle T 1 and candidate relaying is measured
The SD-RSRP of equipment.Next based on the measurement to SD-RSRP, at 410, from selection one in candidate trunking
It is matched after equipment.Suitable trunking has such as been selected at 410, then continues to execute 415.It is as suitable in do not chosen
Trunking then returns to 405, continues to execute the search and measurement of candidate relay equipment.At 415, still measured with cycle T 1
The SD-RSRP of selected trunking and other trunkings in candidate relay equipment.Later, determine whether at 420
Meet condition C 1.Such as in the present embodiment, C1 for example can be that the SD-RPSP of selected trunking continues such as x
The T1 periods are higher than the SD-RPSP of the every other trunking in candidate relay equipment.It should be pointed out that being satisfied it in C1
Before, remote equipment executes the measurement of SD-RPSP with cycle T 1 always.Likewise, x values herein can be prewired on a remote device
It sets, can also be set by RRC signaling by the associated network equipment, such as eNB.If judging that C1 is satisfied at 420, far
Cycle T 1 is transformed to 2 (T2 of cycle T by journey equipment>T1).If judging that C1 is not satisfied at 420, process returns to 415, i.e.,
Remote equipment executes the measurement of SD-RPSP with cycle T 1 always.At 425, the measurement of SD-RPSP is executed with cycle T 2.Later
At 430, determine whether to meet condition C 3.Condition C 3 for example can be whether to meet fallback conditions, such as selected relaying
Equipment is no longer above other trunkings in candidate relay equipment.If condition C 3 is satisfied, process returns to 415, i.e., far
Journey equipment executes the measurement of SD-RPSP with cycle T 1 always.If condition C 3 is not satisfied, and then at 435, determine whether
Meet condition C 2.At this moment the measurement of SD-RPSP is still executed with cycle T 2.Condition C 2 for example can be selected trunking
SD-RPSP continues SD-RPSP of the y T2 period higher than the every other trunking in candidate relay equipment.Likewise, herein
Y values can be pre-configured on a remote device, can also be set by RRC signaling by the associated network equipment, such as eNB.
If condition C 2 is satisfied, cycle T 2 is transformed to 3 (T3 of cycle T by remote equipment>T2).Then it at 440, is held with cycle T 3
The measurement of row SD-RPSP.If condition C 2 is not satisfied, process returns to 425, i.e. remote equipment is executed with cycle T 2 always
The measurement of SD-RPSP.Process at 445 is identical as at 430, therefore details are not described herein.It may be noted that the side in Fig. 4
Method 400 the step of showing or action is merely to illustrate that one embodiment of the disclosure shown in Fig. 4, rather than as right
Realize the restriction of disclosed method.Without departing from the protection domain of the disclosure, those skilled in the art can
