Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made belongs to the scope of protection of the invention.
The embodiments of the invention provide a kind of sending method of trigger signal, as shown in Fig. 1, including：
101, UE (U s e r E qu i pmen t, user equipment）Detect the discovery signal that transfer point is sent.
Wherein, the discovery signal is that transfer point is sent, and the signal of transfer point is found for the UE.Transfer point is base station or the first UE.
It should be noted that the first UE is the UE in addition to the UE.When transfer point is base station, the discovery signal is that base station is sent, and the signal of the base station is found for the UE.Or, when transfer point is a UE, the discovery signal is that the first UE is sent, and the signal of the first UE is found for the UE, and now communication develops into direct communication or the discovery between UE.In the present invention, above-mentioned two situations do not do any restriction, in description below by find signal by base station send exemplified by illustrate, for the first UE send find signal embodiment it is similar, do not repeat.
Specifically, when UE enters the coverage of some cell, UE can receive the discovery signal of this base station broadcast.The discovery signal is in general compared to normal for the synchronizing signal of UE accesses and for the transmission cycle of broadcast singal, cycle is longer, at least hundred milliseconds ranks, such as 200 milliseconds send once, and normally believe for the UE synchronizing signals accessed and broadcast Number the transmission cycle be 10 milliseconds of ranks, such as the synchronous signal cycle of LTE systems is 5 milliseconds, and period of broadcast channel is 10 milliseconds.
The discovery signal can be sent when base station is in dormant state, and when being in dormant state in base station for UE, the cell of base station administration is found in time, and the cell is measured, such as find signal reception power or find the measurement of signal receiving quality etc..Certainly find that signal can also be sent when base station is in activated state, act on as when being in dormant state with base station, do not limit.
It should be noted that the base station defined in embodiments of the present invention, which is in dormant state, means that base station is in base station under the electricity-saving state closed, this state and only sends the discovery signal；And base station refers to base station in activated state and is in normal service state, now in addition to it can continue to send and find signal, in addition it is also necessary to send the synchronizing signal normally accessed for UE, broadcast channel, public reference signal, control channel and data channel etc..
Further, the discovery signal includes：It was found that reference signal or downlink data packet signal.
It should be noted that UE before detection finds signal, it is necessary to the configuration information for finding signal first be obtained, so as to which according to this configuration information, detection finds signal.
It should be noted that the configuration information for finding signal is on receiving or sending the configuration information during discovery signal.For UE, UE, which is obtained, finds that the configuration information of signal refers to that UE is obtained on receiving the configuration information during discovery signal.
Further, signal is found to find that the configuration information includes findings that the candidate sequence and/or running time-frequency resource of signal during reference signal.
F, ^ it/f^ are bad1■!Think Za do f f-Chu/f>Bad '], M/>It is bad] 1 d of G o/f>Bad '] etc., multiple candidate sequences and/or running time-frequency resource can represent that the cell ID of cell is administered in the base station for sending the discovery signal, and such UE can distinguish different cells by detecting the discovery signal.
It was found that when signal is downlink data packet signal, configuration information can include modulation coding mode, the information such as magnitude of load.The configuration information can be with pre-configured, can also be by signal deployment to UE.
Exemplified by finding reference signal, UE detections find that signal can be understood as UE detections institute Some candidate sequences, therefrom match the actual transmission in base station and find the actual sequence that signal is used, the actual sequence is one of candidate sequence, and then determines that the cell ID of current area is administered in the base station by the actual sequence, that is, is found to current area.
Further, it is described to find the status information that signal carries the transfer point.
Wherein, the status information indicates whether the transfer point can be triggered by the UE by way of sending the trigger signal.
102, the UE is according to the configuration information for finding signal acquisition trigger signal.Wherein, the trigger signal is that the UE is sent, and provides the signal of service for the UE for triggering the transfer point.
The configuration information of the trigger signal is on receiving or sending the configuration information during trigger signal.For the UE in the embodiment of the present invention, the configuration information of trigger signal is on sending the configuration information during trigger signal.For example, configuration information includes：The sequence and/or running time-frequency resource information used during triggering information is sent, and sends power information when triggering information.Or, configuration information includes：Send the sequence and/or running time-frequency resource information used during triggering information.
Specifically, U E are before discovery signal is detected, it may be determined that go out this actual disposition information for finding signal, such as actual sequence and/or actual running time-frequency resource, U E can obtain the configuration information of trigger signal according to the actual disposition information for finding signal.
Further, the trigger signal includes：Trigger reference signal or upstream data bag signal.
It should be noted that different according to trigger signal, its corresponding configuration information is also different.Further, include in the trigger signal：In the case of the triggering reference signal, the configuration information of the trigger signal includes：Candidate sequence and/or running time-frequency resource.
It should be noted that, UE can first determine the corresponding relation found between the configuration information of signal and the configuration information of trigger signal, then after the configuration information for finding signal is determined, according to the corresponding relation between the configuration information and the configuration information of trigger signal for finding signal, the configuration information of trigger signal is determined.
Now, when the configuration information of trigger signal includes candidate sequence, UE can be according to the corresponding relation between the configuration information and the configuration information of trigger signal for finding signal, from discovery letter Number configuration information in have corresponding information with the candidate sequence of trigger signal, determine the candidate sequence used during actual transmission trigger signal.
Further, finding the configuration information of signal includes candidate sequence, it is found that the candidate sequence of signal and the candidate sequence of trigger signal have corresponding relation.UE can determine the candidate sequence of trigger signal according to the candidate sequence for finding signal, and this corresponding relation.
Wherein, the candidate sequence of discovery signal can be corresponding corresponding relation or one-to-many corresponding relation with the corresponding relation between the candidate sequence of trigger signal, can also be many-to-one corresponding relation.In addition, it was found that the sequence of signal can be identical with type with the sequence of trigger signal, such as all it is bad ' J or be all M sequences bad ' the J of Z a do f f _ C hu sequences or different types of sequence, such as the sequence for finding signal is M sequence or G o l d (golds）Sequence, and the sequence of trigger signal is Z a d o f f-C hu sequences.
It should be noted that, it was found that the corresponding relation between the candidate sequence of signal and the candidate sequence of trigger signal can also be other corresponding relations, the corresponding relation of such as multi-to-multi, and the corresponding relation can be pre-set, can also be by signaling UE, the present invention is not limited this.
Specifically, if it was found that the corresponding relation between the candidate sequence of signal and the candidate sequence of trigger signal is --- during corresponding corresponding relation, UE is after the candidate sequence for finding signal is determined, the candidate sequence of a trigger signal can be determined according to the candidate sequence and the candidate sequence of trigger signal --- corresponding corresponding relation for finding signal.
If it was found that when the corresponding relation between the candidate sequence of signal and the candidate sequence of trigger signal is one-to-many corresponding relation, UE is after the candidate sequence for finding signal is determined, can be according to the candidate sequence and the one-to-many corresponding relation of the candidate sequence of trigger signal for finding signal, determine the candidate sequence of one group of trigger signal, now UE can choose the candidate sequence of a trigger signal from the candidate sequence of this group of trigger signal, be used as the candidate sequence in the configuration information of trigger signal.
Further, UE can randomly select the candidate sequence of a trigger signal from the candidate sequence of this group of trigger signal, be used as the candidate sequence in the configuration information of trigger signal.Can also be according to the other information in the configuration information for finding signal（Such as current receiving power information for finding signal etc.）The candidate sequence of a trigger signal is chosen, trigger signal is used as Candidate sequence in configuration information.
It should be noted that UE chooses the candidate sequence of a trigger signal from the candidate sequence of one group of trigger signal, other modes are can also be as the method for the candidate sequence in the configuration information of trigger signal, the present invention is without limitation.
If it was found that when the corresponding relation between the candidate sequence of signal and the candidate sequence of trigger signal is many-to-one corresponding relation, UE is after the set of candidate sequences for finding signal is determined, the candidate sequence for the corresponding trigger signal of set of candidate sequences for finding signal can be determined according to the set of candidate sequences and the many-to-one corresponding relation of the candidate sequence of trigger signal for finding signal.Now, the set of candidate sequences of signal can also be found without determination, and directly go out the candidate sequence of trigger signal come unique correspondence with the candidate sequence of the discovery signal detected, because now finding that multiple candidate sequences of signal both correspond to the candidate sequence of trigger signal, a candidate sequence arbitrarily is detected in so the plurality of candidate sequence, the candidate sequence of trigger signal can be uniquely corresponded to out.
It should be noted that UE determines the method for finding the set of candidate sequences of signal, can be that UE detects a candidate sequence in the configuration information for finding signal, UE can determine the corresponding set of candidate sequences of this candidate sequence according to this candidate sequence.Now, UE has prestored all set of candidate sequences for finding signal.Certainly, UE can determine to find the set of candidate sequences of signal by other method, and the present invention is without limitation.
It should be noted that, it was found that when also including other information in the configuration information of signal, such as running time-frequency resource, then can also be the candidate sequence of the other information in the configuration information for finding signal and trigger signal has corresponding relation, for example, it was discovered that the running time-frequency resource of the configuration information of signal and the candidate sequence of trigger signal have corresponding relation.U E according to find signal configuration information other information, and find signal configuration information in other information and trigger signal candidate sequence corresponding relation, obtain trigger signal configuration information.The specifying information for having corresponding relation with the candidate sequence of trigger signal in configuration information of the present invention to finding signal is not limited.
When the configuration information of trigger signal includes running time-frequency resource, UE can be according to the corresponding relation between the configuration information and the configuration information of trigger signal for finding signal, there is corresponding information with the running time-frequency resource of trigger signal from the configuration information for finding signal, determine trigger signal Running time-frequency resource.
Further, finding the configuration information of signal includes running time-frequency resource, it is found that the running time-frequency resource of signal and the running time-frequency resource of trigger signal have corresponding relation.UE can determine the running time-frequency resource of trigger signal according to the running time-frequency resource for finding signal, and this corresponding relation.
Wherein, running time-frequency resource includes：Frequency resource and time-domain resource.
Now, UE can determine the frequency resource of trigger signal according to the frequency resource for finding signal, and its corresponding relation.UE can determine the time-domain resource of trigger signal according to the time-domain resource for finding signal, and its corresponding relation.
Specifically, finding that the frequency resource of signal and the corresponding relation between the frequency resource of trigger signal can send corresponding between the downstream frequency resource for finding signal and the upstream frequency resource for sending trigger signal.For example, transfer point is sent by certain band frequency resource of descending carrier finds signal, now U E can regard the upstream frequency resource corresponding with this downstream frequency resource as the frequency resource in the configuration information of trigger signal.
It should be noted that during frequency resources of the UE in the configuration information for obtaining trigger signal, can not also be by finding that the configuration information of signal is obtained, now, UE oneself can define frequency resource.
It was found that the corresponding relation between the time-domain resource of signal and the time-domain resource of trigger signal can be --- corresponding corresponding relation or one-to-many corresponding relation.
Specifically, if it was found that the corresponding relation between the time-domain resource of signal and the time-domain resource of trigger signal is --- during corresponding corresponding relation, U E can be after the discovery signal that subframe N receives transfer point transmission, can according to find signal time-domain resource between the time-domain resource of trigger signal --- corresponding corresponding relation, UE can regard subframe N+ 4 as the time-domain resource in the configuration information of trigger signal.
It should be noted that UE can be using other subframes such as subframe N+M as the time-domain resource in the configuration information of trigger signal, M is the positive integer more than 0.The present invention is without limitation.Certainly, UE can also utilize other sequential relationships, and the time-domain resource of trigger signal is determined according to the time-domain resource for finding signal.The present invention is without limitation.
If it was found that when the corresponding relation between the time-domain resource of signal and the time-domain resource of trigger signal is one-to-many corresponding relation, UE can receive the discovery letter of transfer point transmission in subframe N After number, the time-domain resource in the configuration information of trigger signal can be regard subframe N+ i as according to the one-to-many corresponding relation between the time-domain resource and the time-domain resource of trigger signal for finding signal, UE.
It is preferred that, i is 4 integral multiple.
It should be noted that UE can determine i value at random, subframe N+ i are regard as the time-domain resource in the configuration information of trigger signal.Certainly, UE can also determine i value according to UE identification information, regard subframe N+ i as the time-domain resource in the configuration information of trigger signal.Above-mentioned N+ i multiple time-domain resources are usually discontinuous subframe, as long as i is not equal to 1, above-mentioned corresponding relation can also correspond to out a string of continuous subframes as time-domain resource, the continuous j subframe that such as N+ i start, that is N+ i, N+ i+1, N+ i+j -10
If it should be noted that can be that UE identifies this to the first integer modulus when UE determines i value according to UE identification information, obtaining remainder, i value is remainder and 4 product.Wherein, the first integer is pre-set.Certainly, UE determines that i value can also be other method according to UE identification information, and the present invention is without limitation.
It should be noted that UE can also determine i value according to other method, the present invention is without limitation.
It should be noted that UE can also obtain the time-domain resource in the configuration information of trigger signal by other method, for example, the time-domain resource in the configuration information of UE setting themselves trigger signals, the present invention is without limitation.
It should be noted that, it was found that when also including other information in the configuration information of signal, such as candidate sequence, then can also be the running time-frequency resource of also other information and trigger signal in the configuration information for finding signal has corresponding relation, for example, candidate sequence and the running time-frequency resource of trigger signal have corresponding relation.UE according to find signal configuration information other information, and find signal configuration information in other information and trigger signal running time-frequency resource corresponding relation, obtain trigger signal configuration information.The specifying information for having corresponding relation with the running time-frequency resource of trigger signal in configuration information of the present invention to finding signal is not limited.
Include in the trigger signal：In the case of the upstream data bag signal, the configuration information of the trigger signal includes：Modulation coding mode, at least one of magnitude of load and running time-frequency resource. Now, when the configuration information of trigger signal includes modulation coding mode, UE can be according to the corresponding relation between the configuration information and the configuration information of trigger signal for finding signal, there is corresponding information with the modulation coding mode of trigger signal from the configuration information for finding signal, determine the modulation coding mode of trigger signal.
Optionally, it was found that the configuration information of signal includes modulation coding mode, it was found that thering is corresponding information to be modulation coding mode with the modulating-coding of trigger signal in the configuration information of signal, then UE can be according to the modulation coding mode for finding signal, and the corresponding relation of the modulation coding mode of signal and the modulation coding mode of trigger signal is found, determine the modulation coding mode of trigger signal.
It should be noted that thering is corresponding information to can also be other information with the modulation coding mode of trigger signal in the configuration information of discovery signal, for example, the candidate sequence of signal, running time-frequency resource etc. are found, the present invention is without limitation.
When the configuration information of trigger signal includes magnitude of load, UE can be according to the corresponding relation between the configuration information and the configuration information of trigger signal for finding signal, there is corresponding information with the magnitude of load of trigger signal from the configuration information for finding signal, determine the magnitude of load of trigger signal.
Optionally, it was found that the configuration information of signal includes magnitude of load, it was found that thering is corresponding information to be magnitude of load with the modulating-coding of trigger signal in the configuration information of signal, then U E can be according to the magnitude of load for finding signal, and the corresponding relation of the magnitude of load of signal and the magnitude of load of trigger signal is found, determine the magnitude of load of trigger signal.
It should be noted that thering is corresponding information to can also be other information with the magnitude of load of trigger signal in the configuration information of discovery signal, for example, the candidate sequence of signal, running time-frequency resource etc. are found, the present invention is without limitation.
It should be noted that UE is according to the configuration information for finding signal, and finds corresponding relation between the configuration information of signal and the configuration information of trigger signal, the configuration information of trigger signal is obtained.The present invention is to having found that the particular content of the configuration information of signal is not limited.It was found that corresponding relation can be pre-set between the configuration information of signal and the configuration information of trigger signal.

Wherein, the first information is carried in the trigger signal.The first information includes：At least one of described receiving power information, the power information of the trigger signal, power offset information and first Timing offset information for finding signal.
The power offset refers to the deviant between the transmit power of the trigger signal and the transmit power of the discovery signal.First Timing offset information refers to that the UE receives the time interval found between signal and the transmission trigger signal.
Specifically, UE is after the configuration information of trigger signal is obtained, it would know that the resource information for sending and being used during trigger signal, the first information can be added in trigger signal by UE, the trigger signal is sent to the transfer point, its configuration information sends trigger signal into transfer point according to i.e., to cause transfer point after trigger signal is received, the first information that can be in trigger signal determines that transfer point switches to activated state by dormant state, or, when transfer point is in activated state, first transmit power is tuned up according to the first information.
Further, first information carrying is had following several by UE in the method for trigger signal.Specifically, the first information can be added directly in the load of trigger signal by UE, the first information is directly carried by the load of trigger signal, is, as the load data of trigger signal, the first information to be added to the first information in trigger signal.
UE can also be carried the first information by the configuration information of trigger signal.Now, it is not that the content of the first information is added directly in the configuration information of trigger signal, but pre-establish the corresponding relation between the configuration information of the first information and trigger signal, transfer point is when receiving trigger signal, the configuration information of trigger signal can be obtained simultaneously, so as to the corresponding relation between the configuration information according to trigger signal, and the first information and the configuration information of trigger signal, the first information is obtained.That is, carrying the first information by the configuration information of trigger signal.

So, base station is when receiving trigger signal, when the candidate sequence for knowing this trigger signal is 1, according to the corresponding relation between the receiving power information of candidate sequence and discovery signal, it would know that candidate sequence finds the received power value a of signal for 1 correspondence, or correspondence finds that the receiving power rank of signal is 1, so as to obtain the first information.
It should be noted that UE carries the first information by trigger signal, and can also be using other methods, the present invention is without limitation.
Further, when carrying the status information of the transfer point in finding signal, the UE is according to the configuration information of the trigger signal, and sending the trigger signal to the transfer point includes：
The status information indicate the transfer point can by the UE by way of sending the trigger signal to trigger when, the UE sends the trigger signal according to the configuration information of the trigger signal to the transfer point.

The embodiments of the invention provide a kind of method of reseptance of trigger signal, as shown in Fig. 2, including：
201, transfer point determines to find the configuration information of signal and sends the discovery signal according to the configuration information of the discovery signal.
Wherein, the discovery signal is that transfer point is sent, and the signal of the transfer point is found for user equipment (UE).Transfer point can be base station or the first UE. It should be noted that the configuration information for finding signal is on receiving or sending the configuration information during discovery signal.For transfer point, transfer point determines that the configuration information for finding signal is that transfer point is determined on sending the configuration information during discovery signal.
It should be noted that the first UE is the UE in addition to the UE.Now, when transfer point is base station, the discovery signal is that base station is sent, and the signal of the base station is found for UE.Or, when transfer point is a UE, the discovery signal is that the first UE is sent, and the signal of the first UE is found for U E.Now communication develops into direct communication or the discovery between UE.In the present invention, above-mentioned two situations do not do any restriction, in description below by find signal by base station send exemplified by illustrate, for the first UE send find signal embodiment it is similar, do not repeat.
Specifically, can pre-set the configuration information for finding signal in base station, as base station can pre-set the resource information sent when finding signal, such as Time-Frequency Information, candidate sequence etc..Base station is after the configuration information for finding signal is determined, base station in a dormant state when, or base station is active, but when being reduction of the transmit power for sending common signal, discovery signal can be sent by way of broadcast according to its configuration information with some cycles, so that the UE around base station has found and accesses this base station.The discovery signal is in general compared to normal for the synchronizing signal of UE accesses and for the transmission cycle of broadcast singal, cycle is longer, at least hundred milliseconds ranks, such as 200 milliseconds send once, and normally the transmission cycle for the UE synchronizing signals accessed and broadcast singal is 10 milliseconds of ranks, the such as synchronous signal cycle of L TE systems is 5 milliseconds, and period of broadcast channel is 10 milliseconds.
It should be noted that when base station is in activated state and sends the transmit power of common signal without reduction, discovery signal can also be sent by way of broadcast, the present invention is without limitation.
It should be noted that base station in embodiments of the present invention, which is in dormant state, means that base station is in base station under the electricity-saving state closed, this state and only sends the discovery signal；And base station refers to base station in activated state and is in normal service state, now in addition to it can continue to send and find signal, in addition it is also necessary to send the synchronizing signal normally accessed for UE, broadcast channel, public reference signal, control channel and data channel etc..
Further, it is described to find to carry the power information for being found signal in signal.

Transfer point can will be seen that the power information of signal is added directly in the load for finding signal, the power information for finding signal is directly carried by the load of discovery signal, it as will be seen that the power information of signal as the load data for finding signal, it may be found that the power information of signal, which is added to, to be found in signal.
Transfer point can also will be seen that the power information of signal by finding that the candidate sequence of signal is carried, and now, transfer point and UE need to pre-set the corresponding relation between the power information for finding signal and the candidate sequence for finding signal.Transfer point is according to the power information for finding signal, the candidate sequence for finding signal is set, this discovery signal is sent to U E, to cause UE after this discovery signal is received, can be according to the corresponding relation between the power information of the discovery signal pre-set and the candidate sequence of discovery signal, and the candidate sequence of signal is found, determine the transmit power for finding signal.
Exemplary, it is assumed that transfer point is base station, and base station need to be pre-set with UE finds that the candidate sequence 1 of signal represents that the transmission power value for finding signal is Q, it is found that the candidate sequence 2 of signal represents that the transmission power value for finding signal is P.When the transmit power that discovery signal is sent in base station is Q, base station, which is set, finds that the candidate sequence of signal is 1, and will be seen that signal is sent to U E, during so that UE receiving discovery signal, the candidate sequence 1 for finding signal can be known, and the corresponding relation between the power information and the candidate sequence of discovery signal according to default discovery signal, it is Q to determine the transmission power value for finding signal.
It should be noted that in embodiments of the present invention, finding to carry the specific method for the power information for being found signal in signal, can also be other method, the present invention is without limitation.
It should be noted that UE obtain transfer point send find signal when, it is necessary to first obtain find signal configuration information.Now, transfer point and UE can also pre-establish the corresponding relation between the configuration information for finding signal and the power information for finding signal, so that U E are when getting the configuration information for finding signal, it can know that transfer point is sent by the corresponding relation between the configuration information of the default discovery signal set up and the power information of discovery signal It was found that transmit power during signal.Now, transfer point will be seen that the transmit power of signal by finding that the configuration information of signal is carried.

Wherein, the first information is carried in the trigger signal.The first information includes：At least one of described receiving power information, the power information of the trigger signal, power offset information and first Timing offset information for finding signal.
The power offset refers to the deviant between the transmit power of the trigger signal and the transmit power of the discovery signal.First Timing offset information refers to that the UE receives the time interval found between signal and the transmission trigger signal.
It should be noted that the configuration information of the trigger signal is on receiving or sending the configuration information during trigger signal.For the transfer point in the embodiment of the present invention, the configuration information of trigger signal is on receiving the configuration information during trigger signal.For example, configuration information includes：The sequence and/or running time-frequency resource information used during triggering information is received, and receives power information when triggering information.Or, configuration information includes：Receive the sequence used during triggering information and/or running time-frequency resource information etc..
Specifically, transfer point can be after the configuration information for finding signal be determined, Ke Yigen It is found that the configuration information of signal knows the configuration information of trigger signal.Now, transfer point needs first to determine have corresponding relation between the configuration information of the discovery signal and the configuration information of the trigger signal, so as to know the configuration information of trigger signal according to the configuration information for finding signal.
It should be noted that find configuration information and the trigger signal of signal matches somebody with somebody confidence, between there is corresponding relation to pre-set.
Further, the trigger signal includes：Trigger reference signal or upstream data bag signal.

Further, the method for the first information is carried in the trigger signal following several.Specifically, the first information directly by trigger signal load-bearing, be using the first information as trigger signal load data.
The first information can also be carried by the configuration information of trigger signal, now, it is not the content that the first information is directly carried in the configuration information of trigger signal, but pre-establish the configuration information of trigger signal and the corresponding relation of the first information, so as to, transfer point can know the first information according to the configuration information of trigger signal, and the corresponding relation between the first information and the configuration information of trigger signal.
It should be noted that the method for the first information is carried in trigger signal, and can also be using other methods, the present invention is without limitation.
2 03, the transfer point obtains the first information from the trigger signal.
Specifically, transfer point is when getting trigger signal, different according to the method that trigger signal carries the first information, the method for obtaining the first information is also different.
If the first information is directly by the load-bearing of trigger signal, during as using the first information as the load data of trigger signal, transfer point directly parses trigger signal, from trigger signal The first information is obtained in load-bearing.
If the first information is carried by the configuration information of trigger signal, transfer point can know the first information according to the configuration information of trigger signal, and the corresponding relation between the first information and the configuration information of trigger signal.
Exemplary, assuming that transfer point is base station, if the first information includes findings that the candidate sequence carrying in the receiving power information of signal, the configuration information that the first information is passed through into trigger signal, the corresponding relation between candidate sequence and the receiving power information for finding signal has as been pre-established.For example, the received power value a that the correspondence of candidate sequence 1 finds signal has been pre-established, or correspondence finds that the receiving power rank of signal is 1;The correspondence of candidate sequence 2 finds that the received power value b of signal, or correspondence have found that the receiving power rank of signal is 2 corresponding relation.So, base station is when receiving trigger signal, when the candidate sequence for knowing this trigger signal is 1, according to the corresponding relation between the receiving power information of candidate sequence and discovery signal, it would know that candidate sequence finds the received power value a of signal for 1 correspondence, or correspondence finds that the receiving power rank of signal is 1, so as to obtain the first information.
