In S201, the first configuration information is the configuration information for N number of reference signal that relay node is sent to user equipment, N ≥1。

Wherein, the configuration information of N number of reference signal includes at least one of following information: the transmission of N number of reference signal Time；The carrier frequency of N number of reference signal；The sequence of N number of reference signal；The subcarrier spacing of N number of reference signal；N number of reference The port information of signal；The reference signal of N number of reference signal indexes.

In interference detecting method shown in Fig. 2, base station can be the first equipment above-mentioned, and relay node can be aforementioned The second equipment, user equipment can be third equipment above-mentioned.Certainly, aforementioned first equipment is also possible to remove in relay system Another relay node other than second equipment, aforementioned third equipment are also possible to another in addition to the second equipment in relay system One relay node does not limit this in the embodiment of the present application.

It should be noted that base station actively can send the first configuration information to relay node in S201, can also be based on The request of relay node sends the first configuration information to relay node, does not limit this in the embodiment of the present application.Further, since Relay node can be sent when sending reference signal to user equipment based on different numerology, thus base station is to relaying It may further indicate that relay node when sending reference signal to user equipment based on which in the first configuration information that node is sent Numerology is sent.

Optionally, relay node can be according to the first configuration after base station sends the first configuration information to relay node in S201 Information sends N number of reference signal to user equipment, then, base station can survey N number of reference signal according to the first configuration information Amount, to determine the link (i.e. access link) between relay node and user equipment to base station and relay node according to measurement result Between link (i.e. return link) interference.

Specifically, N number of reference signal that relay node is sent to user equipment can be sent using different shaped-beams. For example, N number of shaped-beam, which can be used, in relay node sends N number of reference signal to user equipment respectively, at this point, the first configuration information Instruction relay node be can be used to when sending reference signal using which shaped-beam.So, base station can be according to first Configuration information measures the link (i.e. access link) under N number of shaped-beam between relay node and user equipment and saves to base station and relaying The interference of link (i.e. return link) between point.

After base station carries out interference measurement to N number of reference signal, base station needs to indicate relaying section according to measurement result Point is sent in the subsequent transmission signal to user equipment based on which kind of configuration, is done with reducing access link to return link It disturbs.The indicating mode can there are many, two of them mode is set forth below.

Mode one

After base station carries out interference measurement to N number of reference signal, base station can send third configuration information to relay node, Third configuration information is the configuration information of at least one reference signal in N number of reference signal, so that relay node can root Signal is sent to user equipment according to third configuration information, to reduce interference of the access link to return link.

In mode one, after carrying out interference measurement to N number of reference signal, base station can be sieved according to measurement result for base station It selects at least one reference signal in N number of reference signal, and the configuration information of at least one reference signal is sent to After node.Measurement result mentioned here may include at least one of following information: the reference signal of N number of reference signal connects Receive the channel quality instruction of power (reference signal receiving power, RSRP), N number of reference signal Signal-to-noise ratio (the signal-to- of (channel quality indicator, CQI), N number of reference signal Interference rate, SIR), Signal to Interference plus Noise Ratio (the signal to interference of N number of reference signal Plus noise ratio, SINR).That is, base station can be surveyed when relay node sends reference signal to user equipment One or more of parameters such as RSRP, CQI, SIR or SINR of the reference signal are measured, the ginseng is then determined according to measurement result Examine interference of the access link where signal to return link；It, can basis after the measurement to N number of reference signal is completed in base station The measurement result of N number of reference signal filters out at least one reference signal, by the configuration information (of at least one reference signal Three configuration informations) it is sent to relay node.

Wherein, at least one reference signal that base station filters out can be in when access link interferes smaller to return link After the corresponding reference signal sent of node.Particularly, when relay node sends N to user equipment respectively using N number of shaped-beam When a reference signal, at least one base station selected reference signal and at least one shaped-beam are corresponded, that is to say, that base Stand to the third configuration information that relay node is sent indicate relay node using at least one above-mentioned shaped-beam to user When equipment sends at least one reference signal, access link is smaller to the interference of return link.So, relay node is receiving After third configuration information you can learn that: it is subsequent to user equipment send signal when, at least one above-mentioned shaped-beam can be used It sends, to reduce interference of the access link to return link.

It should be noted that in the embodiment of the present application, information type that the first configuration information and third configuration information include It can be different.For example, the first configuration information may include the sending time and carrier frequency of N number of reference signal, third matches confidence Breath may include the port information and reference signal index of at least one reference signal；Alternatively, the first configuration information may include N The sequence and carrier frequency of a reference signal, third configuration information may include at least one reference signal subcarrier spacing and Carrier frequency.

Mode two

After base station carries out interference measurement to N number of reference signal, base station can be sent in N number of reference signal to relay node At least one reference signal measurement result；Correspondingly, relay node receives in N number of reference signal that base station is sent at least The measurement result of one reference signal, so that relay node is determined according to the measurement result of at least one reference signal rear Continue and is sent during sending signal to user equipment based on which kind of configuration.

Wherein, the measurement result of at least one reference signal includes following at least one: the mark of at least one reference signal Knowledge or configuration information；The RSRP of at least one reference signal；The CQI of at least one reference signal；At least one reference signal SIR；The SINR of at least one reference signal.

It should be noted that not only may include at least in the measurement result of at least one reference signal in mode two The parameter of one reference signal, such as RSRP, CQI, SIR and SINR, can also include at least one reference signal mark and Configuration information, this is because: if base station only to relay node send at least one reference signal RSRP, CQI, SIR and One or more of parameters such as SINR, it is relay node to user that relay node, which is difficult to pick out this at least one reference signal, Which reference signal in N number of reference signal that equipment is sent.Therefore, base station can send at least one ginseng in the measurement results The mark and configuration information of signal are examined, for relay node recognizes at least one reference signal.Wherein, at least one is joined The configuration information for examining signal includes at least one of following information: the sending time of at least one reference signal；At least one The carrier frequency of reference signal；The sequence of at least one reference signal；The subcarrier spacing of at least one reference signal；At least one The port information of a reference signal；The reference signal of at least one reference signal indexes.

Mode two and mode one the difference is that: in mode one, at least one reference signal is base station according to N number of ginseng Examine what the measurement result of signal filtered out, and base station sent to relay node be at least one reference signal configuration information (i.e. third configuration information), relay node can matching based at least one reference signal in the subsequent transmission signal to user equipment Confidence breath (i.e. third configuration information) is sent；And at least one reference signal in mode two can be base station according to measurement As a result preliminary screening goes out from N number of reference signal, is also possible to not by N number of reference signal of screening, and base station is in After node send be at least one reference signal measurement result, relay node is in the survey for receiving at least one reference signal After measuring result, further at least one reference signal can be screened, can be based in the subsequent transmission signal to user equipment The configuration information of all or part of reference signal at least one reference signal is sent.

In addition, in order to enable measurement result is more accurate, relay node is each in interference detecting method shown in Fig. 2 While sending reference signal to user equipment, reference signal can also be sent to base station on the same running time-frequency resource, in order to just The reference signal that relay node is sent to base station is known as " the second reference signal " in differentiation, the embodiment of the present application.Work as relaying Node is when sending reference signal to user equipment and base station on the same running time-frequency resource, in access link and return link simultaneously There are data transmission, thus measurement result in this case can be more accurate.Particularly, in above process, relay node The second reference signal sent to base station can be zero energy reference signal (zero power reference signal, ZP RS).That is, relay node is used for the reference signal of interference measurement simultaneously to user equipment transmission on the same running time-frequency resource ZP RS is sent to base station, at this point, since access link and return link occupy the running time-frequency resource, thus in the running time-frequency resource On reference signal transmission not will receive the interference of other signals, base station measures reference signal on the running time-frequency resource, Measurement result is more accurate.

In interference detecting method shown in Fig. 2, since base station has sent the first configuration information to relay node, and first Configuration information is the configuration information for N number of reference signal that relay node is sent to user equipment, that is to say, that relay node can be with N number of reference signal is sent to user equipment according to the first configuration information.Since the first configuration information is known for base station , thus N number of reference signal that base station can send relay node to user equipment based on the first configuration information is interfered Measurement, so that base station can be with the link (i.e. access link) between acquiring relay node and user equipment between base station and relay node Link (i.e. return link) interference.

It should be noted that since relay node can be based on different when sending reference signal to user equipment Numerology is sent, thus may further indicate that relay node base when sending reference signal to user equipment in the second configuration information Which sent in numerology.

The difference of embodiment two and embodiment one is pointed out to be: in embodiment one, the configuration information (of N number of reference signal One configuration information) it is that relay node is sent to after being determined by base station, relay node can match confidence based on the first of base station transmission It ceases to user equipment and sends N number of reference signal, base station can carry out interference measurement according to the first configuration information itself determined；And it is real It applies in example two, the configuration information (i.e. the second configuration information) of N number of reference signal is to be sent to base station after being determined by relay node, Relay node can send N number of reference signal to user equipment based on the second configuration information itself determined, and base station can also be with base Interference measurement is carried out in the second configuration information received from relay node.

Optionally, relay node can be according to the second configuration after relay node sends the second configuration information to base station in S401 Information sends N number of reference signal to user equipment, then, base station can survey N number of reference signal according to the second configuration information Amount, to determine the link (i.e. access link) between relay node and user equipment to base station and relay node according to measurement result Between link (i.e. return link) interference.

Specifically, N number of reference signal that relay node is sent to user equipment can be to be sent out using different shaped-beams It send.For example, N number of shaped-beam, which can be used, in relay node sends N number of reference signal to user equipment respectively, at this point, second matches Which shaped-beam confidence breath can be used to instruction relay node when sending reference signal using.So, base station can root According to the second configuration information measure the link (i.e. access link) under N number of shaped-beam between relay node and user equipment to base station and The interference of link (i.e. return link) between relay node.

Mode one

In mode one, after carrying out interference measurement to N number of reference signal, base station can be sieved according to measurement result for base station It selects at least one reference signal in N number of reference signal, and the configuration information of at least one reference signal is sent to After node.Measurement result mentioned here may include at least one of following information: the RSRP of N number of reference signal, N number of ginseng Examine the CQI of signal, the SIR of N number of reference signal, N number of reference signal SINR.That is, in relay node to user equipment When sending reference signal, base station can measure one of parameters such as RSRP, CQI, SIR or SINR of the reference signal or several Kind, interference of the access link where the reference signal to return link is then determined according to measurement result；When base station is completed to N After the measurement of a reference signal, at least one reference signal can be filtered out according to the measurement result of N number of reference signal, extremely by this The configuration information (third configuration information) of a few reference signal is sent to relay node.

It should be noted that in the embodiment of the present application, information type that the second configuration information and third configuration information include It can be different.For example, the second configuration information may include the sending time and carrier frequency of N number of reference signal, third matches confidence Breath may include the port information and reference signal index of at least one reference signal；Alternatively, the second configuration information may include N The sequence and carrier frequency of a reference signal, third configuration information may include at least one reference signal subcarrier spacing and Carrier frequency.

Mode two

In addition, in order to enable measurement result is more accurate, relay node is each in interference detecting method shown in Fig. 4 While sending reference signal to user equipment, reference signal can also be sent to base station on the same running time-frequency resource, in order to just The reference signal that relay node is sent to base station is known as " the second reference signal " in differentiation, the embodiment of the present application.Work as relaying Node is when sending reference signal to user equipment and base station on the same running time-frequency resource, in access link and return link simultaneously There are data transmission, thus measurement result in this case can be more accurate.Particularly, in above process, relay node The second reference signal sent to base station can be ZP RS.That is, relay node is on the same running time-frequency resource to user Equipment sends the reference signal for interference measurement and sends ZP RS to base station, at this point, since access link and return link are equal The running time-frequency resource is occupied, thus the reference signal transmission on the running time-frequency resource not will receive the interference of other signals, base station exists Reference signal is measured on the running time-frequency resource, measurement result is more accurate.

In interference detecting method shown in Fig. 4, since relay node has sent the second configuration information to base station, and second Configuration information is the configuration information for N number of reference signal that relay node is sent to user equipment, that is to say, that relay node can be with N number of reference signal is sent to user equipment according to the second configuration information, base station can also save relaying based on the second configuration information N number of reference signal that point is sent to user equipment carries out interference measurement, so that base station can be with acquiring relay node and user equipment Between interference of the link (i.e. access link) to the link (i.e. return link) between base station and relay node.

Based on the description above to embodiment two, the embodiment of the present application also provides a kind of interference detecting method, which surveys Amount method can be considered a specific example of method shown in Fig. 4, and method shown in this method and Fig. 4 can cross-reference.Referring to Fig. 5, This method comprises the following steps:

S501: relay node sends first message to base station, is used to indicate relay node and sends to user equipment with reference to letter Number when the running time-frequency resource used.

Wherein, used running time-frequency resource can be considered side shown in Fig. 4 when relay node sends reference signal to user equipment A specific example of the second configuration information in method.

As previously mentioned, the second configuration information is the configuration information for N number of reference signal that relay node is sent to user equipment. The configuration information of N number of reference signal includes at least one of following information: the sending time of N number of reference signal；N number of reference letter Number carrier frequency；The sequence of N number of reference signal；The subcarrier spacing of N number of reference signal；The port information of N number of reference signal； The reference signal of N number of reference signal indexes.So, in method shown in Fig. 5, relay node sends reference signal to user equipment When used running time-frequency resource can be considered the sending time of N number of reference signal and the carrier frequency of N number of reference signal.

In addition, relay node can also send N number of ZP RS to base station on above-mentioned running time-frequency resource in S502.Wherein, ZP RS For a specific example of the second reference signal in method shown in Fig. 4.Since the power of ZP RS is zero, thus relay node is real Not oriented base station sends reference signal on border, and only occupies the running time-frequency resource between base station and relay node.It does so Benefit be: relay node on the same running time-frequency resource to user equipment send for interference measurement N number of reference signal simultaneously N number of ZP RS is sent to base station, at this point, the reference signal sent on the running time-frequency resource not will receive the interference of other signals, base station Reference signal can be measured on the running time-frequency resource, to accurately determine interference of the access link to return link.

S503: interference of the access link to return link under the base station measurement shaped-beam.

By S502~S503 execute n times: i.e. every time execution S502 when relay node be all made of different shaped-beams to Family equipment sends parameter signal, and access link does return link under each shaped-beam of base station measurement when executing S503 every time It disturbs.So, by the way that S502~S503 is executed n times, base station can determine that access link does return link under N number of shaped-beam It disturbs.

S504: base station sends a notification message to relay node, to notify relay node when sending signal to user equipment The shaped-beam set that can be used.

In S504, tax that relay node includes in the shaped-beam set that can use when sending from signal to user equipment Shape wave beam is at least one shaped-beam in aforementioned N number of shaped-beam.

In S504, base station can be considered method shown in Fig. 4 by the shaped-beam set that notification message is indicated to relay node In third configuration information a specific example.In method shown in Fig. 4, third configuration information is that base station is sieved according to measurement result The configuration information of at least one reference signal in reference signal select, N number of, and in method shown in Fig. 5, shaped-beam set At least one shaped-beam in shaped-beam filtered out for base station, N number of；In the method as shown in Fig. 5, N number of shaped-beam It is one-to-one with N number of reference signal, thus base station indicates relay node using in N number of shaped-beam by notification message At least one shaped-beam sends signal to user equipment, that is, base station is N number of to relay node transmission in method shown in Fig. 4 The configuration information (i.e. third configuration information) of at least one reference signal in reference signal.

In S504, base station can be high-level signaling or DCI to the notification message that relay node is sent.Wherein, high-level signaling Including but not limited to: RRC information, MAC CE, broadcast message, system message etc..

By method shown in Fig. 5, base station can configure used figuration when relay node sends signal to user equipment Beam set, to reduce interference of the access link to return link.

Embodiment three

It is a kind of interference detecting method provided by the embodiments of the present application referring to Fig. 6.This method comprises the following steps:

S601: relay node sends measurement result to base station；Correspondingly, base station receives the measurement knot that relay node is sent Fruit.

Wherein, measurement result is at least one of N number of reference signal that user equipment is sent to relay node with reference to letter Number measurement result, N >=1.

In interference detecting method shown in Fig. 6, base station can be the first equipment above-mentioned, and relay node can be aforementioned The second equipment, user equipment can be third equipment above-mentioned.Certainly, aforementioned first equipment is also possible to remove in relay system Another relay node other than second equipment, aforementioned third equipment are also possible to another in addition to the second equipment in relay system One relay node does not limit this in the embodiment of the present application.

In S601, when relay node sends measurement result to base station, can be used different reporting schemes: relay node can be with The measurement result or relay node for reporting at least one reference signal one by one can be by the measurement knots of at least one reference signal Fruit uniformly reports；In addition, relay node while the measurement result for reporting at least one reference signal, can also report at least one The ordering scenario of the measurement result of a reference signal.

Specifically, in S601, the measurement result of at least one reference signal may include following at least one: at least one ginseng Examine the mark or configuration information of signal；The RSRP of at least one reference signal；The CQI of at least one reference signal；At least one The SIR of reference signal；The SINR of at least one reference signal.That is, being sent to relay node with reference to letter in user equipment Number when, relay node can measure one or more of parameters such as RSRP, CQI, SIR or SINR of the reference signal, then Interference of the access link where the reference signal to return link is determined according to measurement result；When relay node is completed to N number of After the measurement of reference signal, that is, it can determine the measurement result of N number of reference signal.In so S601, relay node reports N to base station It include two kinds of situations: the first situation, relay node root when the measurement result of at least one reference signal in a reference signal At least one reference signal is filtered out according to the measurement result of N number of reference signal, and by the measurement result of at least one reference signal It is reported to base station, here, at least one reference signal that relay node filters out can be access link and interfere return link The user equipment corresponding reference signal sent when smaller；Second situation, relay node do not execute screening movement, directly will be N number of The measurement result of reference signal is reported to base station.

It should be noted that not only may include at least one reference signal in the measurement result of at least one reference signal Parameter, such as RSRP, CQI, SIR and SINR can also include the mark and configuration information of at least one reference signal, this is Cause are as follows: if relay node only sends one in the parameters such as RSRP, CQI, SIR and SINR of at least one reference signal to base station A or multiple, base station is difficult to pick out at least one reference signal to be N number of reference signal that user equipment is sent to relay node In which reference signal.Therefore, relay node can send the mark of at least one reference signal in the measurement results and match Confidence breath, for base station recognizes at least one reference signal.Wherein, the configuration information of at least one reference signal includes At least one of following information: the sending time of at least one reference signal；The carrier frequency of at least one reference signal；Extremely The sequence of a few reference signal；The subcarrier spacing of at least one reference signal；The port information of at least one reference signal； The reference signal of at least one reference signal indexes.

In addition, base station can Xiang Zhongji before the measurement result that relay node sends at least one reference signal to base station Node sends resource allocation information, which is used to indicate the measurement that relay node sends at least one reference signal Used resource when as a result.So, relay node can indicate after receiving resource allocation information in resource allocation information Resource on to base station send measurement result.

Optionally, before relay node sends measurement result to base station, base station can send first to relay node and match Confidence breath, the first configuration information are the configuration information of N number of reference signal.Wherein, the configuration information of N number of reference signal includes following At least one of information: the sending time of N number of reference signal；The carrier frequency of N number of reference signal；The sequence of N number of reference signal Column；The subcarrier spacing of N number of reference signal；The port information of N number of reference signal；The reference key of N number of reference signal.

It should be noted that base station actively can send the first configuration information to relay node, it can also be based on relaying section The request of point sends the first configuration information to relay node, does not limit this in the embodiment of the present application.Further, since user sets It is standby to be sent based on different numerology when sending reference signal to relay node, thus base station is sent out to relay node It may further indicate that user equipment when sending reference signal to relay node based on which in the first configuration information sent Numerology is sent.

After base station sends the first configuration information to relay node, the first configuration information can be sent to use by relay node Family equipment, then user equipment when sending above-mentioned N number of reference signal to relay node, can be carried out based on the first configuration information It sends.While user equipment sends reference signal to relay node, relay node can also be according to the first configuration information to N A reference signal measures.

Specifically, N number of reference signal that user equipment is sent to relay node can be carried out using different shaped-beams It sends.For example, N number of shaped-beam, which can be respectively adopted, in user equipment sends N number of reference signal to relay node, at this point, first matches Which shaped-beam confidence breath can be used to instruction user equipment when sending reference signal using.So, relay node The link (i.e. access link) under N number of shaped-beam between relay node and user equipment can be measured according to the first configuration information to base The interference for the link (i.e. return link) stood between relay node.

In addition, in method shown in Fig. 6, measurement of the base station at least one reference signal for receiving relay node transmission As a result after, further at least one reference signal can be screened according to the measurement result, and to relay node after screening The second configuration information is sent, the second configuration information is all or part of reference signal at least one reference signal with confidence Breath.Wherein, the configuration information of all or part of reference signal includes at least one of following information: all or part of with reference to letter Number sending time；The carrier frequency of all or part of reference signal；The sequence of all or part of reference signal is all or part of The subcarrier spacing of reference signal；The port information of all or part of reference signal；The reference of all or part of reference signal is believed Number index.

Wherein, all or part of reference signal that base station filters out can be access link to return link interference it is smaller when The corresponding reference signal sent of user equipment.Particularly, it is sent when N number of shaped-beam is respectively adopted in user equipment to relay node When N number of reference signal, at least one reference signal and at least one shaped-beam that relay node filters out are corresponded.Assuming that The quantity for all or part of reference signal that base station filters out is M, M >=1, then also there is M shaped-beam with this M with reference to letter Number correspond.That is, the second configuration information that base station is sent to relay node, which indicates user equipment, is using above-mentioned M When a shaped-beam sends M reference signal to relay node, access link is smaller to the interference of return link.So, it relays Node is can notifying user equipment after receiving the second configuration information: it is subsequent send signal to relay node when, can be used Above-mentioned M shaped-beam is sent, to reduce interference of the access link to return link.

Optionally, the second configuration information that base station is sent to relay node may further indicate that the survey of all or part of reference signal Measure sort result situation.For example, the measurement result at least one reference signal that relay node is sent in S601 to base station is The RSRP of at least one reference signal, then base station is filtering out all or part of reference signal from least one reference signal Afterwards, when sending the second configuration information to relay node, all or part of reference signal can be also indicated in the second configuration information RSRP according to ordering scenario from high to low or from low to high.

In addition, in order to enable measurement result is more accurate, user equipment is each in interference detecting method shown in Fig. 6 While sending reference signal to relay node, base station can also be sent to relay node with reference to letter on the same running time-frequency resource Number, for the ease of distinguishing, the reference signal that base station is sent to relay node is known as " the second reference signal " in embodiment three.When User equipment and base station are when sending reference signal to relay node on the same running time-frequency resource, in access link and return link Data transmission is existed simultaneously, thus relay node can be more accurate to the measurement result of N number of reference signal in this case.Especially Ground, in above process, the second reference signal that base station is sent to relay node can be ZP RS.That is, relay node Reference signal that user equipment is sent, for interference measurement can be received on the same running time-frequency resource, and receives base station The ZP RS of transmission, at this point, since access link and return link occupy the running time-frequency resource, thus on the running time-frequency resource Reference signal transmission not will receive the interference of other signals, and relay node can survey reference signal on the running time-frequency resource Amount, measurement result are more accurate.

In interference detecting method shown in Fig. 6, relay node sends the measurement knot of at least one reference signal to base station Fruit, wherein at least one reference signal is the reference of at least one of N number of reference signal that user equipment is sent to relay node Signal.Base station can filter out all or part from least one reference signal according to the measurement result of at least one reference signal Reference signal, and the configuration information of all or part of reference signal is sent to relay node.Wherein, the whole that base station filters out Or part reference signal can be the user equipment corresponding reference signal sent when access link interferes smaller to return link.In After the configuration information of all or part of reference signal is sent to user equipment by node, user equipment is subsequent to relay node It can be sent based on the configuration information of all or part reference signal when sending signal, to reduce access link to passback chain The interference on road.

Based on the description above to embodiment three, the embodiment of the present application also provides a kind of interference detecting method, which surveys Amount method can be considered a specific example of method shown in Fig. 6, and method shown in this method and Fig. 6 can cross-reference.Referring to Fig. 7, This method comprises the following steps:

S701: user equipment sends request message to relay node, and request base station configures user equipment and sends out to relay node Used running time-frequency resource when sending reference signal.

Wherein, used running time-frequency resource can be considered side shown in Fig. 6 when user equipment sends reference signal to relay node A specific example of the first configuration information in method.

As previously mentioned, the first configuration information is the configuration information for N number of reference signal that user equipment is sent to relay node. The configuration information of N number of reference signal includes at least one of following information: the sending time of N number of reference signal；N number of reference letter Number carrier frequency；The sequence of N number of reference signal；The subcarrier spacing of N number of reference signal；The port information of N number of reference signal； The reference signal of N number of reference signal indexes.So, in method shown in Fig. 7, user equipment sends reference signal to relay node When used running time-frequency resource can be considered the sending time of N number of reference signal and the carrier frequency of N number of reference signal.

S702: the request message that user equipment is sent is transmitted to base station by relay node.

S703: base station sends response message to relay node, sends reference signal to configure user equipment to relay node When used running time-frequency resource.

In addition, base station can also configure from above-mentioned running time-frequency resource and send N number of ZP RS to relay node in S703.Its In, ZP RS is a specific example of the second reference signal in method shown in Fig. 6.Since the power of ZP RS is zero, thus base Actually not oriented relay node of standing sends reference signal, and only occupies the time-frequency money between base station and relay node Source.The advantage of doing so is that: relay node receives from user equipment, for interference measurement on the same running time-frequency resource N number of reference signal, and N number of ZP RS from base station is received, at this point, the reference signal sent on the running time-frequency resource will not be by To the interference of other signals, relay node measures reference signal on the running time-frequency resource, and measurement result is more accurate.

In S703, base station can be high-level signaling or DCI to the response message that relay node is sent.Wherein, high-level signaling Including but not limited to: RRC information, MAC CE, broadcast message, system message etc..

S704: user equipment is saved using a shaped-beam in N number of shaped-beam to relaying on above-mentioned running time-frequency resource Point sends reference signal.

S705: relay node measures interference of the access link to return link under the shaped-beam.

Specifically, relay node can on the occupied running time-frequency resource of ZP RS measuring reference signals RSRP, CQI, SIR With the parameters such as SIN, so that it is determined that interference of the access link to return link under the shaped-beam.

S704~S705 is executed n times: user equipment is all made of different shaped-beams in when executing S704 every time Parameter signal is sent after node, relay node measures under each shaped-beam access link to return link when executing S705 every time Interference.So, by the way that S704~S705 is executed n times, relay node can determine that access link is to passback under N number of shaped-beam The interference of link.

S706: relay node is to base station report measurement results.

Wherein, relay node to the measurement result that base station reports be at least one reference signal in N number of reference signal Measurement result.Here include two kinds of situations: the first situation, relay node are filtered out according to the measurement result of N number of reference signal At least one reference signal, and the measurement result of at least one reference signal is reported to base station, here, relay node filters out At least one reference signal can be access link it is smaller to return link interference when corresponding reference the letter sent of user equipment Number；Second situation, relay node do not execute screening movement, the measurement result of N number of reference signal are directly reported to base station.
