Several specific examples are provided below in conjunction with above-mentioned any embodiment：

Only by taking base station (gNB) as an example, the method in this example applied to base station can equally answer network side in this example Deployment for network sides such as cell (cell), cell (small cell), transmitting and receiving point (TRP), access points (AP) is set It is standby.

First example：

Measurement/the coordination being related between two or more base stations, the span link interference for mainly solving base station are surveyed Amount problem.

Base station by prepare/carrying out uplink receiving measures, and uplink receiving base station can be sent out by neighbouring downlink Send base station across link interference, need to reduce this across link interference, promote communication quality, it is necessary first to carry out this across link The measurement of interference.

As shown in fig. 6, the second base station gNB2 downlink transmission the uplink receiving of first base station gNB1 can be caused base station it Between across link interference.In order to carry out across the link interference coordination between base station and eliminate, gNB1 is needed to gNB2 to gNB1's Channel/interference situation measures.

When gNB1 is measured, other than receiving the reference signal of gNB2 transmissions, it is possible to can be by gNB1 adjacent to other The interference of base station or UE in cell are inaccurate so as to cause measuring such as the gNB3 or UE3-1 in Fig. 6.

Across the link interference detection between base station can be carried out by following one or more steps.

Step 1: neighbouring gNB is by return link (backhaul, such as X2 interface or privately owned interface) or eats dishes without rice or wine (such as OTA signalings) send at least one following information：Reference signal sends configuration information, gNB measurement configuration informations.Neighbouring gNB is extremely Few includes sending base station and measuring base station, further, including measures the neighbor base station of base station.

Send base station：In measurement process, sends base station and send reference signal, for measuring.For example, when interference base station is sent out When sending DL, interfered base station UL receptions can be caused across link interference.In measurement process, interference base station sends reference signal, For measuring.Therefore, transmission base station here is interference base station, such as the gNB2 in Fig. 6.

Measure base station：In measurement process, measures base station and receive the reference signal for sending base station transmission, execute measurement.Example Such as, disturbed base station UL receive can be interfered base station DL transmission across link interference.In measurement process, disturbed base station receives The reference signal that interference base station is sent, executes measurement.Therefore, measurement base station here is disturbed base station, such as the gNB1 in Fig. 6.

The span link interference that the reference signal at least can be used for gNB measures.It is described in this example dry across link Measurement is disturbed to may include：RRM measurements, CSI/CQI measurements or interference measurement or path loss measure.

Reference signal for base station measurement can be DL DMRS, CSI-RS or special measurement signal；New measurement letter Number such as the newly-designed signal measured for RRM or channel/interference measures, such as symmetrical DL RS of uplink and downlink RS.Optionally, it uses In base station measurement reference signal be CSI-RS.The special measurement signal can be the measurement letter specially designed in this example Number.

Optionally, above-mentioned reference signal carries cell/Base Station Identification (Identiy, ID) information.It is described include it is following at least One of：The number of cell physics ID or sending point ID (such as TRP ID or AP ID) or cell/base station/sending device.It takes Can be implicit or display with mode.Implicit mode can be scrambled or be participated in the sequence life of reference signal by above-mentioned ID At.

It includes at least one following that reference signal, which sends configuration information,：Transmission subframe/time slot configuration information, sending cycle/ Sending deviation information, sends pattern configuration information, silence (muted-RS) resource allocation information at port information.

Subframe/time slot configuration information is sent, gNB is used to indicate in which subframe/time slot to send reference signal, generally passes through Corresponding sending cycle and/or sending deviation determine or aperiodic triggering is sent.

Pattern configuration information is sent, the time-frequency pattern of the RS (CSI-RS) of gNB transmissions is used to indicate, such as in subframe/time slot Which symbol and which RE on send reference signal.

Muted-RS resource allocation informations, be used to indicate send muted-RS subframe/time slot or running time-frequency resource pattern, Or port, and RS is sent with zero energy in these resources.

GNB measurement configuration informations include at least one following：Measurement object information measures subframe/time slot configuration information, surveys Amount period/measurement deviates/measures duration information, measures pattern configuration information, muted-RS resource allocation informations.

Measurement object information, the channel/interference situation being used to indicate between gNB measurements and which gNB, measurement object can It is indicated with renumbering with cell ID or to gNB.

Subframe/time slot configuration information is measured, is used to indicate gNB in which subframe/time slot to receive or measuring reference signals, It is generally determined by corresponding measurement period and/or measurement offset and/or measurement duration or aperiodic triggering is surveyed Amount.

Pattern configuration information is measured, the time-frequency pattern that gNB measures RS (CSI-RS) is used to indicate, as in subframe/time slot Which symbol and measuring reference signals on which RE.

Silent (muted-RS) resource allocation information, is used to indicate the subframe/time slot or running time-frequency resource for sending muted-RS Pattern or port, and RS is sent with zero energy in these resources.Base station measures the channel of adjacent area/dry in these resources Disturb situation.

For example, neighbouring gNB1, gNB2 and gNB3 in Fig. 6 passes through return link (backhaul, such as X2 interface or private Have interface) or the following reference signal CSI-RS of (such as OTA signalings) interaction that eat dishes without rice or wine send configuration information and/or gNB measuring configurations are believed Breath.

As shown in fig. 7, the also adjacent area each other the adjacent area each other gNB1 and gNB2, gNB1 and third base station gNB3.That is, gNB1 Adjacent area is gNB2 and gNB3；The adjacent area of gNB2 is gNB1；The adjacent area of gNB3 is gNB1.These configuration informations can only adjacent area it Between interaction.

Sending configuration information and measurement configuration information can interact in different time points, can also only interact between the base stations Configuration information is sent, without interaction measurement configuration information.Both information can be interacted in different moments, can also unidirectionally be handed over Mutually.For example, at the T0 moment, gNB2 sends signal to gNB1 and sends configuration information；And at the T1 moment, gNB1 is sent out to gNB2 and gNB3 Give its measurement configuration information.

Configuration generation can be sent according to the signal for sending base station by measuring the measurement configuration information of base station.For example, measurement base Measurement subframe/the time slot stood can be：Send the subset or complete of transmission subframe/time slot of the transmission reference signal in configuration information Collection.For example, it is 20ms (assuming that offset is 0) to send the period that base station signal is sent, namely in sons such as subframes 0/20/40/60/80 Frame is sent.The measurement period for measuring base station is 40ms, namely is measured in subframes such as subframes 0/40/80.

It is to send in the period to send base station and send reference signal, can also be aperiodic transmission.The aperiodic transmission It may include：Triggering based on trigger event is sent.Measurement base station measurement can also be aperiodic across link interference or triggering measures. In some cases, the reference signal for sending base station is periodicity sending, and the measurement for measuring base station is then non-periodic measurement.

Step 2: send gNB sends reference signal according to above-mentioned transmission configuration information.GNB is measured according to measuring configuration to be believed Breath receives the reference signal, and executes measurement.

Optionally, it measures gNB measuring in resource, does not dispatch or do not receive uplink signal/channel from this cell； Or, the UE that notice exempts from scheduling does not send UL signals/channel measuring in resource；Or measure the row of the upstream or downstream in resource Execute silence (muting) operation.Here measurement resource can be and the predetermined running time-frequency resource in previous embodiment.

Optionally, other neighbouring gNB of gNB are measured according to the measuring configuration for measuring gNB, are executed in its measurement resource quiet Silent operation operation, does not send channel/signal, or work in such a way that muted-RS/ transmission powers are zero.Herein other GNB does not include sending gNB.

Optionally, measuring other neighbouring gNB of gNB notifies its subordinate UE, subordinate UE to be held in the measurement resource for measuring gNB Row silent operation does not send UL signals or channel.

For example, being directed to Fig. 6, the downlink transmission of gNB2 can cause across link interference the uplink receiving of gNB1.In order to carry out Across link interference coordination and elimination, gNB1 need to measure the channel conditions and/or disturbance regime of gNB2 to gNB1.In T0 Moment, gNB2 send signal to gNB1 and send configuration information.At the T0-1 moment, gNB2 starts to send with reference to letter according to configuration is sent Number.At the T1 moment, gNB1 sends its measurement configuration information to gNB2 and gNB3.At the T1-1 moment, gNB1 connects according to measuring configuration It receives the signal and executes measurement.T0-1 and T1-1 can be that synchronization or T1-1 are later than T0-1.GNB3 is also according to gNB1 Measuring configuration do not sent in the measurement resource of gNB1 channel/signal or execute muted-RS operation.Further, gNB3 is logical Know that its subordinate UE, subordinate UE execute silent operation in the measurement resource of gNB1, do not send UL signals or channel.

When down channel/disturbance regime between gNB1 is to gNB2 to gNB1 measures, gNB1 can be interfered GNB3 and/or its subordinate UE muting at this time, not can determine disturbing factor when reducing gNB1 tests, improve measurement Accuracy contributes to further interference coordination and elimination.

It measures gNB to measure the channel/interference situation between gNB2 to gNB1, RRM measurement results can be obtained (such as Reference Signal Received Power (RSRP)/received signal strength indicator device (RSSI)/Reference Signal Received Quality that gNB is measured Or CSI/CQI measurement results or interference measurement results (RSRQ)).

By measuring, at least one following channel or interference information can be obtained：Precise channel measurement result, channel square Battle array, feature vector, covariance matrix, interference matrix, interference strength (or interference strength grade classification), RRM measurement results, CQI/ PMI/RI。

Step 3: optional, measure gNB by measurement result information by return link (backhaul, such as X2 interface) or Eat dishes without rice or wine (such as OTA signalings) be sent to send gNB.

GNB1 measures down channel/disturbance regime between gNB2 to gNB1, can obtain RRM measurement results (RSRP/RSSI/RSRQ that such as gNB is measured) or CSI/CQI measurement results or interference measurement results.

Transmitted measurement result information can be the precise information or quantitative information of above-mentioned measurement result, may include as It is at least one lower：Precise channel measurement result, channel matrix, feature vector, covariance matrix, interference matrix, interference strength (or Interference strength grade classification), RRM measurement results, CQI/PMI/RI.

For example, measuring gNB measures RSRP or path loss.RSRP is smaller or path loss is bigger, indicates to send base station distance measurement base It stands remoter.When measuring base station reception UL, by the smaller across link interference of transmission base station DL.So at this time across link interference The ascending power of UE should be influenced smaller.It, will not shadow across link interference when across link interference measurement result is near or approximately at 0 Ring the ascending power of UE.Bigger across link interference, the ascending power of UE should be bigger.

Opposite, RSRP is bigger or path loss is smaller, and it is closer to indicate that transmission base station distance measures base station.It is received when measuring base station When UL, by the bigger across link interference of transmission base station DL.Lifting is so needed to measure the ascending power of base station subordinate UE at this time, Or the mechanism such as the interference coordination of step 4 is used, to reduce the influence sent to UL across link interference.

Step 4：According to measurement result or the measurement result information interacted, interference association is executed between two adjacent gNB It adjusts, interference coordination operation specifically may include at least one following：

GNB is sent when dispatching DL, target downlink signal/channel is mapped in the kernel of interference channel；

GNB is sent when dispatching DL, the direction of analog beam is avoided measuring gNB；

GNB is measured when dispatching UL, is received without using omnidirectional, avoids receiving the wave beam from the directions gNB are sent；

Measure gNB when dispatch UL, if at this time exist transmission gNB to UL receive across link interference, can take down One of row mode avoids interference：The UL transmissions for measuring gNB can be lifted power, delay is sent, changes modulating-coding strategy (MCS), change and send carrier wave, cancel transmission etc..

Send gNB when dispatch DL, if at this time exist send gNB to measure gNB UL reception across link interference, can To take one of following method：Send gNB DL transmission can reduce power, delay send, change MCS, change send carrier wave, Cancel transmission etc..

Step 5: when sending DL signals due to measuring gNB, the UL receptions for sending gNB can also be caused across link interference.Cause This, sends gNB and is also required to obtain the channel/interference situation measured between gNB to transmission gNB.

Mode one：Based on channel heterogeneite, the measurement result information of the measurement gNB received by step 3 is sent GNB, which can convert to obtain, measures gNB to the channel/interference situation sent between gNB.For example, gNB will be sent to measurement gNB's Channel matrix carries out transposition, you can obtains and measures gNB to the channel matrix for sending gNB.

Mode two：Execute step 1 arrive step 3, send gNB measurements obtain measure gNB to transmission gNB between channel/ Disturbance regime.At this point, measuring gNB sends reference signal, and sends gNB and execute measurement.

Second example,

Base station by prepare/carrying out downlink transmission measures, and the base station that downlink is sent can be on neighbouring other The base station that row receives is caused across link interference, and the main purpose of measurement is sent on other base stations for reducing this base station down Row receive across link interference.

This example is with the first exemplary main distinction：

In this example, it is disturbed base station to send base station, such as the gNB1 of Fig. 6, sends base station and sends reference signal, for surveying Amount.Measurement base station is interference base station, such as the gNB2 of Fig. 6, measures base station and receives the reference signal for sending base station transmission, execute survey Amount.

In addition, this exemplary measurement result is also different with the first example from across link interference relationship：

For example, measuring the reception power (RSRP) or path loss of gNB measuring reference signals.

RSRP is smaller or path loss is bigger, and it is remoter to indicate that transmission base station distance measures base station.DL signals are sent when measuring base station When, the UL to sending base station is smaller across link interference caused by receiving, then DL letters can be sent with relatively high power by measuring gNB Number.

RSRP is bigger or path loss is smaller, and it is closer to indicate that transmission base station distance measures base station.DL signals are sent when measuring base station When, the UL signals to sending base station are bigger across link interference caused by receiving.It so needs to reduce the downlink for measuring base station at this time Power, or the mechanism such as the interference coordination of step 4 is used, it reduces caused by being received to the UL for sending base station across link interference It influences.

In addition to the differences mentioned above, this exemplary measurement process with the first exemplary measurement process is same or like (especially walks Rapid one arrives step 3).Alternatively, this exemplary measurement result can also be based on by the first exemplary step one to step 3 measurement result Channel reciprocity obtains.

Third example：

Measurement/the coordination being related between two or more UE, to realize across the link interference measurement between UE.

UE by prepare/carrying out downlink reception is measured, and downlink reception UE can be sent UE by neighbouring uplink Across link interference, the measurement result after measuring can be used for reducing other UE uplinks send to this UE downlink receptions across link Interference.

Step 1: sending UE reference signal is sent according to configuration information is sent.UE is measured to be received according to measurement configuration information The reference signal, and execute measurement.

Send UE：In measurement process, sends UE and send reference signal, for measuring.For example, when interference UE sends UL letters Number when, can to the DL of disturbed UE receive cause across link interference.In measurement process, interference UE sends reference signal, for surveying Amount.Therefore, transmission UE here is interference UE.Such as the UE1-1 in Fig. 6.

Measure UE：In measurement process, measures UE and receive the reference signal for sending UE transmissions, execute measurement.For example, disturbed The DL of UE receive that the UE UL that can be interfered send across link interference.In in measurement process, disturbed UE receives interference UE and sends Reference signal, execute measurement.Therefore, measurement UE here is disturbed UE.Such as the UE2-1 in Fig. 6.

It is duplexing (TDD) for dynamic Time Division, it sends UE and measures UE and adhere to different cells separately.For full duplex, UE is sent Same cell is may belong to UE is measured, different cells can also be adhered to separately.

The reference signal at least can be used for the measurement between UE, the measurement between UE here can be used for RRM measure, CSI/CQI measurements or interference measurement or path loss measure.

Can be UL DMRS, SRS or new measuring signal for the UE reference signals measured；New measuring signal is for example new The signal of design measured for RRM or channel/interference measures, such as the uplink reference signals in uplink and downlink reference signal (RS) (UL RS).Optionally, it is Sounding Reference Signal (SRS) to be used for the reference signal that UE is measured.

In order to reduce the complexity of the measurement between UE, or some interactive unnecessary information less, for being measured between UE Reference signal sent with constant power value or predetermined power value.Namely the reference signal for being measured between UE can not use Row power control.The reason is that if the reference signal power is variation, it needs to notify the UE to reference signal is sent Own base station, and need by the base station notify to measure UE own base station.

In other words, unless receiving measured signal power change or new power value information, measuring UE can assume to measure letter Number power it is constant.

Optionally, above-mentioned reference signal carries cell ID/ base station informations.Including at least one following：Cell physics ID or The number of sending point ID (such as TRP ID or AP ID) or cell/base station/sending device.Carrying mode can be implicit Or display.The sequence that implicit mode could be scrambled or be participated in reference signal by above-mentioned ID generates.

Optionally, above-mentioned reference signal carries the id information of UE.Such as：Cell Radio Network Temporary Identifier/Identity, Cell-RNTI (C-RNTI), Or UE numbers.Similar, carrying mode can be implicit carrying mode or display carrying mode.Implicit carrying mode can pass through Above-mentioned UE id informations scrambling or the sequence for participating in reference signal generate, and carry out recessive reference, and the display carries directly to carry institute State id information.The UE labels may include the UE numbers in the numbers of the UE in cell or set of cells.The recessiveness carrying mode, Can other information and id information be carried in receiving terminal is by the reference signal by reference to the other information that is carried in signal Mapping relations or transformational relation obtain the id information.

It includes at least one following that reference signal, which sends configuration information,：Transmission subframe/time slot configuration information, sending cycle/ Sending deviation information, port information, letter send pattern configuration information, muted-RS resource allocation informations.

Subframe/time slot configuration information is sent, UE is used to indicate in which subframe/time slot to send reference signal, generally leads to Cross corresponding sending cycle and/or sending deviation determine or aperiodic triggering send.

Send pattern configuration information, be used to indicate UE transmission RS (SRS) time-frequency pattern, such as subframe/time slot where Reference signal is sent on a little symbols and which RE；Muted-RS resource distributions be used to indicate send muted-RS subframe/time slot, Or running time-frequency resource pattern or port, and RS is sent with zero energy in these resources.

UE measurement configuration informations include at least one following：Measurement object information measures subframe/time slot configuration information, surveys Amount period/measurement deviates/measures duration information, measures pattern configuration information, muted-RS resource allocation informations.

Measurement object information, instruction UE measure the channel/interference situation between which UE, and measurement object can use UE ID renumbers to indicate to UE.

Subframe/time slot configuration information is measured, is used to indicate UE in which subframe/time slot to receive or measuring reference signals, It is generally determined by corresponding measurement period and/or measurement offset and/or measurement duration or aperiodic triggering is surveyed Amount.

Measure pattern configuration information, be used to indicate UE measure RS (SRS) time-frequency pattern, such as subframe/time slot which Symbol and measuring reference signals on which RE；Muted-RS resource distributions be used to indicate send muted-RS subframe/time slot or Running time-frequency resource pattern or port, and RS is sent with zero energy in these resources.UE measures neighbouring UE in these resources and arrives The channel/interference situation of oneself.

It sends configuration information and is sent to transmission UE by sending UE own base stations.Measurement configuration information is by measuring UE own base stations It is sent to and measures UE.Further, send UE send reference signal can by the aperiodic triggering in the base station, and/or, measure UE Measuring reference signals can also be by the aperiodic triggering in the base station.

Further, send configuration information by return link or can eat dishes without rice or wine to be sent to measurement by sending UE own base stations UE own base stations and/or the adjacent base station for sending base station described in UE.Further, it is sent out by measuring base station and/or adjacent base station described in UE Give subordinate UE.

Further, measurement configuration information by return link or can eat dishes without rice or wine to be sent to transmission by measuring UE own base stations UE own base stations and/or the adjacent base station for measuring UE own base stations.

Generation can be configured according to the transmission for sending UE by measuring the measuring configuration of UE.For example, measure UE measurement subframe/when Gap can be subset or the complete or collected works for sending UE and sending configuration.For example, send UE signals send period be 20ms (assuming that deviate be 0) it, namely in subframes such as subframes 0/20/40/60/80 sends.The measurement period for measuring UE is 40ms, namely in subframe 0/40/80 Etc. subframes measure.

It can be aperiodic or triggering transmission to send the reference signal that UE is sent for measuring UE measurements；Measure UE measure across Link interference can also be aperiodic or triggering measures.Alternatively, the former is periodicity sending, the latter is non-periodic measurement.

Optionally, it measures UE and does not receive downlink signal/channel from this cell in resource measuring.Or base station is being surveyed Silent operation operation is executed in amount resource or does not dispatch DL transmissions.It measures base station described in UE and does not dispatch other UE in resource measuring Carry out UL transmissions.

Optionally, other neighbouring UE (not including sending UE) of UE are measured according to the measuring configuration for measuring UE, in its measurement Silent operation operation is executed in resource, does not send channel/signal, or work in a manner of zero transmission powers of muted-RS/.It is neighbouring Other UE can be and measure UE with cell or adjacent cell.The measuring configuration for measuring UE can be by measuring base station described in UE And/or its adjacent base station is notified to the adjacent UE for measuring UE.

When measurement UE is measured to sending UE to the down channel/disturbance regime measured between UE, to measuring UE meetings Other UE interfered muting at this time, reduce to measure and not can determine disturbing factor when UE is measured, and improve measurement Accuracy contributes to further interference coordination and elimination.

It measures UE and is measured to the channel/interference situation measured between UE to sending UE, RRM measurement results can be obtained (RSRP/RSSI/RSRQ that such as gNB is measured) or CSI/CQI measurement results or interference measurement results or path loss.

At least one following channel or interference information can be obtained：Precise channel measurement result, channel matrix, feature to Amount, covariance matrix, interference matrix, interference strength (or interference strength grade classification), RRM measurement results, CQI/PMI/RI.

UE own base stations are measured Step 2: measuring UE and being reported to measurement result information.Optionally, UE own base stations are measured By return link (backhaul, such as X2 interface) or eat dishes without rice or wine to be sent to base station as described in transmission UE (such as OTA signalings).

Transmitted measurement result information can be the precise information or quantitative information of above-mentioned measurement result, may include as It is at least one lower：Precise channel measurement result, channel matrix, feature vector, covariance matrix, interference matrix, interference strength (or Interference strength grade classification), RRM measurement results, CQI/PMI/RI.Here precise information can directly include various measured values, The quantitative information is information of the measured value by hierarchical processing.

For example, measuring UE measures RSRP or path loss.RSRP is smaller or path loss is bigger, indicates that sending UE range measurements UE gets over Far.When measuring UE reception DL, by the smaller across link interference of transmission UE UL.So at this time across link interference to measure The corresponding descending powers of UE should influence smaller.When across link interference measurement result is near or approximately at 0, not across link interference It can influence the descending power adjustment of UE.Bigger across link interference, the descending power of UE should be bigger.

Opposite, RSRP is bigger or path loss is smaller, indicates that transmission UE range measurements UE is closer.When measuring UE reception DL, By the bigger across link interference of transmission UE UL.It so needs lifting to measure the corresponding descending powers of UE at this time, or uses example The interference coordination mechanism of such as step 3 to reduce the influence received to DL across link interference, or even does not send or postpones to send DL gives measurement UE.

Step 3：According to measurement result or the measurement result information interacted, executed across chain between two adjacent gNB or UE Road interference coordination specifically may be used such as at least one of under type：

UE is sent when carrying out UL transmissions, target uplink signal/channel is mapped in the kernel of interference channel；

UE is sent when carrying out UL transmissions, the direction of analog beam is avoided measuring UE；

It when base station sends DL to UE is measured, measures UE and is received without using omnidirectional, avoid receiving from the directions transmission UE Wave beam；

Measure UE when receiving DL, if at this time exist transmission UE to DL receive across link interference, can take following At least one：The corresponding DL transmissions of measurement UE can be lifted power, delay is sent, change MCS, change sends carrier wave, cancels Send etc..

UE is sent when sending UL, UE is sent to measurement UE DL receptions across link interference if existed at this time, can adopt Remove at least one row：The UL transmissions of transmission UE can reduce power, delay is sent, change MCS, change sends carrier wave, cancels Send etc..

Step 4: opposite, when sending UL due to measuring UE, the DL receptions for sending UE can also be caused across link interference. Therefore, UE is sent at this time and/or its described base station is also required to obtain and measures UE to the channel/interference situation sent between UE.

Mode one：Reciprocity based on channel, the measurement result information of the measurement UE received by step 2, sends The affiliated gNB of UE, which can convert to obtain, measures UE to the channel/interference situation sent between UE.For example, UE will be sent to measurement UE Channel matrix carry out transposition, you can obtain measure UE to transmission UE channel matrix.

Mode two：Step 1 is executed to step 2, UE measurements is sent and obtains measuring UE to the channel/interference sent between UE Situation.At this point, measuring UE sends reference signal, and sends UE and execute measurement.

4th example：

Measurement/the coordination being related between two or more UE, the span link interference measurement for mainly solving UE are asked Topic.

UE by prepare/carrying out uplink transmission is measured, and the UE that uplink is sent can connect other neighbouring downlinks The UE of receipts is caused across link interference, the main purpose of measurement be for reducing this UE uplinks send to other UE downlink receptions across Link interference.

This example is with the exemplary main distinction of third：In this example,

Transmission UE is disturbed UE, such as the UE1-2 of Fig. 6, sends UE and sends reference signal, for measuring.

It is interference UE to measure UE, such as the UE1-1 of Fig. 6, measures UE receptions and sends the reference signal that UE is sent, execute measurement.

For example, measuring UE measures RSRP or path loss.

RSRP is smaller or path loss is bigger, indicates that transmission UE range measurements UE is remoter.When measuring UE transmission UL, to sending UE DL receive caused by it is smaller across link interference, then measure UE can with larger UL power send or normal power send.Across Link interference influences the uplink power control for measuring UE smaller.

Opposite, RSRP is bigger or path loss is smaller, indicates that transmission UE range measurements UE is closer.When measuring UE transmission UL, DL to sending UE is bigger across link interference caused by receiving.It so needs to reduce the ascending power for measuring UE at this time, or uses Such as the mechanism such as interference coordination of third exemplary step three, it reduces caused by being received to the DL for sending UE across link interference contribution. It does not send even or postpones to send.

In addition to the differences mentioned above, this exemplary measurement process with the first exemplary measurement process is same or like (especially walks Rapid one arrives step 2).Alternatively, this exemplary measurement result can also be based on by the first exemplary step one to step 2 measurement result Channel reciprocity obtains.

5th example：

It is related to the measurement of two categories, for across the link interference measurement between base station or between UE.

First category is statistical across link interference measurement：Alternatively referred to as semi-static across link interference measurement.Such as first Example is measured to the RRM in the 4th example.Statistics across the link interference measurement general measure time is long or frequency domain is wide, measurement result Stablize relatively.

For example, by example one or two, gNB1 can measure interference or channel matrix of the gNB2 to oneself；GNB2 can also Measure interference or channel matrix of the gNB1 to oneself.

For example, by example three or four, UE1-1 can measure interference or channel matrix of the UE2-1 to oneself；UE2-1 Interference or channel matrix of the UE1-1 to oneself can be measured.

Two neighbor base stations or two neighbouring UE can be measured by a side, and another party obtains according to channel reciprocity.Also may be used It is all measured with both sides.

Second category is instantaneously across link interference measurement：The transient measurement time is very short, such as a few us to hundreds of us.Instantaneously Across link interference measurement be mainly used for equipment identification adjacent equipment sending direction.

The interference detecting method that this example is related to：Across the link interference measurement of statistics obtains RRM measurement results and/or letter Road/disturbance regime；Instantaneously across link interference measurement obtains interference source or interference radiating way.

By across the link interference measurement of statistics, gNB1 measures disturbed condition or channel matrix of the gNB2 to oneself；gNB2 Disturbed condition or channel matrix of the gNB1 to oneself can also be measured.But gNB1 or gNB2 is except transmission between base station for measuring at this time Reference signal, be practically without business transmission.In other words, gNB1 receives UL business, but gNB2 may be sent without DL at all, Also gNB1 would not be caused across link interference.That is, although gNB1 obtains gNB2 to across the link interference feelings of the possibility of oneself Condition or channel matrix, but actually there is no occur across link interference at this time.But across link interference problem once occurs, this The result measured in advance may be used for interference coordination or interference is eliminated.

When gNB2 has DL transmissions, it can send detectable signal RS2 in the default position that sends.Then, if gNB1 has UL Business, gNB1 or UE1-1 can execute instantaneously across link interference measurement in the default position that measures, and receive RS2, judge that gNB2 has at this time DL is sent.Along with the gNB2 measured in advance can between link interference, gNB1 or the two neighbouring gNB to gNB1 To execute interference coordination or interference cancellation mechanisms.This is equally applicable to across the link interference measurement between UE and UE.

It sends the default transmission position of above-mentioned detectable signal and executes instantaneously across the default measurement position that link interference measures There are incidence relations, such as be all distributed in a time window or one/multiple symbols in or a blank resource in.

6th example：

It is related to across link interference thresholding problem,

Mode one：

Set the first threshold value and/or the second threshold value.It is specific as follows：

The first threshold value is set, if across link interference measurement result is less than or is less than or equal to the first threshold value, also To illustrate to be not present across link interference at this time, or ignore in the presence of across link interference.Data can be at this time It is normal to send, interference elimination method need not be used.This transmission behavior is properly termed as normal transmission mode.

If across link interference measurement result be more than or be more than or equal to the first threshold value, namely can illustrate at this time exist across Link interference, and influence whether that data are sent.At this time must use interference elimination method could send, or not this moment across Link is sent.This transmission behavior is properly termed as after AF panel sending mode or be known as cannot across link transmission mould simultaneously Formula.

Further, the second threshold value is set.Here, the second threshold value is more than the first threshold value.

If across link interference measurement result is more than or is more than or equal to the first threshold value, but is less than or is less than or equal to second Limit value, namely can illustrate exist at this time across link interference, but be not very serious.It need not stop sending or send in the same direction, But it could be sent after interference elimination method must being used.Namely it needs using sending mode after above-mentioned AF panel.It can make With following mechanism：1, power lifting or reduction；2, MCS is changed；

If across link interference measurement result is more than or is more than or equal to the first threshold value, and is more than the second threshold value, namely It can illustrate exist at this time across link interference, and very serious.It cannot be sent immediately with interference negative direction at this time.Namely it needs to make With it is above-mentioned cannot simultaneously across link sending mode.Following mechanism can be used：1, it is sent in the same direction with the interference source measured.Such as it is dry Disturbing source, sending direction is DL at this time, then local area should also be DL, that is, ensure identical sending direction；2, stop sending；3, postpone It sends；4, using different running time-frequency resources, for example, using different Physical Resource Block (PRB) or subband.5, the load sent is replaced Wave；Etc..

Further, there is the following two kinds embodiment：

1, network side configures the first threshold value and/or the second threshold value, base station or UE according to the measurement knot across link interference Fruit independently selects corresponding sending mode according to mentioned above principle based on the comparison result with thresholding.

2, according to across link interference measurement result, (across the link interference measurement result can be that base station oneself measures for base station Gained can also be to be reported after UE is measured), directly above-mentioned sending mode is configured using or to UE.

8th example：

It is related to interference scenes more particularly to transmitting terminal of the gNB between gNB and uses directional beam (directional beam), And receiving terminal receives the interference problem under scene using omnidirectional.

(UE2-1/UE2-2/UE2-3 under gNB1 and gNB2) is sent using directional beam as shown in fig. 7, transmitting terminal, And receiving terminal (UE1-1 under gNB1 and gNB2) is received using omnidirectional.

If there is gNB1 has wave beam to beat to gNB2, namely this side up, gNB1 has downlink transmission.No matter is this when Which position UE sends UL data to gNB2 in gNB2 coverage areas, all can by between base station across link interference.That is, being It is no that there are the downlinks of a base station to the transmission wave beam for depending primarily on gNB1 across link interference of the uplink of another base station.

It can one of as follows or the combinations of multiple steps solves the problems, such as this：

Step 1: executing interference identifing source.Namely interfering beam identification.Interference base station sends ginseng in each directional beam Signal is examined, disturbed base station receives reference signal and executes measurement.

Further, disturbed base station is given the serial number of interfering beam or the corresponding channel/interference condition feedback of serial number dry Disturb base station.Optionally, disturbed base station is only corresponding to oneself maximum one or several interfering beam serial number of interference or serial number Channel/interference condition feedback to interference base station.

This process is interfered and is needed through return link (backhaul, such as X2 between gNB and disturbed gNB similar to example one Interface) or at least one the following information of (such as OTA signalings) interaction of eating dishes without rice or wine：Reference signal sends configuration information, gNB measuring configurations Information.Further, on the basis of example one, it further includes the wave for sending gNB (interference gNB) that reference signal, which sends configuration information, Beam serial number (wave beam ID) or wave beam serial number and corresponding reference signal send configuration information.

Measurement result information is indicated to interference gNB by disturbed gNB.Further, on the basis of example one, knot is measured Fruit information further includes wave beam serial number and corresponding measurement result information, alternatively, disturbed gNB is to oneself interference maximum one A or multiple wave beam serial numbers feed back to interference gNB.

For example, gNB1DL is sent, there are 4 wave beams, respectively send (TX) wave beam 1, TX wave beams 2, TX wave beams 3, TX wave beams 4, gNB1 send reference signal respectively in this 4 wave beams, and gNB2 sends reference signal according to each wave beam that gNB1 is indicated Configuration information is sent, reference signal is received and executes measurement.Obtain the corresponding channel/interference matrix of each wave beam, then Each wave beam serial number and corresponding channel/interference condition feedback are to gNB1.Alternatively, after assessment, only to oneself interference Maximum one or several wave beam serial numbers are sent to gNB1.

Here, suppose that the TX wave beams 1 of gNB1, which receive the UL of gNB2, influences maximum.GNB1TX wave beams 1 and gNB2's is all Uplink receiving constitutes an interference pair.

Step 2: the interfering beam or channel/interference situation, interference base station and disturbed base station that are determined according to step 1 execute Across link interference coordination.

Downlink transmission in gNB TX wave beams 1 is limited or is coordinated, including at least one of：

A. for interference gNB when dispatching DL transmissions, directional beam does not use TX wave beams 1；

B. interference gNB is mapped in target downlink signal/channel in the kernel of interference channel when dispatching DL transmissions. The interference channel can be measured by being disturbed the RS that gNB receptions are sent in TX wave beams 1, then feed back to interference gNB；Alternatively, RS is sent by disturbed gNB, interference gNB measures a channel, then obtains the interference matrix according to channel heterogeneite；

C. DL power is reduced.It reduces and the UL of gNB2 is interfered.

D. it receives the scheduling of gNB2 or sends information, sending direction with the DL/UL of gNB2 is aligned.When gNB2 is sent When DL, gNB1 just can send DL in TX wave beams 1.

When e.gNB1 has downlink transmission, gNB2 is notified, dispatching uplink is not sent gNB2.

F., priority can be set, the TX wave beams 1 of gNB1 downlinks be low priority send (the reason is that it is one side of interference, And all UL in adjacent area can be interfered to receive).Only when adjacent area does not send or sent without the directions UL, just in the TX wave beams 1 into Row DL is sent.

G. it is sent without DL in this wave beam.Or DL transmissions can be just configured with longer cycle/interval.

H. gNB is disturbed when dispatching UL transmissions, is received without using omnidirectional, avoids receiving the wave for coming the directions self-interference gNB Beam.It can be to utilize the signal received on each direction that omnidirectional, which receives, in the present invention, and directional reception can be only receiving part Divide the signal on direction.

I. be disturbed gNB when dispatch UL send when, if at this time in the presence of interference gNB to UL receive across link interference, can To take one of following method：The UE UL of disturbed gNB, which are sent, can be lifted power, delay is sent, change MCS, change transmission Carrier wave, cancellation transmission etc.；

Interfere gNB when scheduling DL is sent, if there is interference gNB at this time to being disturbed the dry across link of gNB UL receptions It disturbs, one of following method can be taken：The DL of interference gNB, which is sent, can reduce power, delay is sent, change MCS, change transmission Carrier wave, cancellation transmission etc..

In addition, other of gNB1 and gNB2 direction TX wave beams can be not limited to the above.

8th example：

It is (fixed using directional beam to be related to interference scenes more particularly to transmitting terminal and receiving terminal of the gNB between gNB To wave beam) interference problem under scene.

As shown in figure 8, transmitting terminal is sent using directional beam, and receiving terminal is received using directional beam.At this point, only When the RX wave beams of gNB2 and the TX wave beams of gNB1 have overlapping, just there is uplink of the downlink signal to another base station of a base station It causes across link interference.

It below can be one or more of as follows this across link interference to detect：

Step 1: executing interference identifing source.Namely interfering beam identification.Interference base station sends ginseng in each directional beam Signal is examined, disturbed base station receives reference signal in each directional beam and executes measurement.Each interfering beam and reception wave beam A transmitting and receiving wave beam pair can be formed.When interference is present or interference is more than pre-determined threshold, interfering beam can be referred to as It is right.

For example, gNB1DL is sent, there are 4 wave beams, respectively TX wave beams 1, TX wave beams 2, TX wave beams 3, TX wave beams 4, gNB1 Send reference signal respectively in this 4 wave beams, there are 4 wave beams for gNB2 receptions, respectively receive (RX) wave beam 1, RX wave beams 2, RX wave beams 3, RX wave beams 4.According to each beam reference signal configuration of gNB1 instructions, gNB2 is in each reception directional beam It receives reference signal and executes measurement.So the matrix of a 4*4 will be formed：

[TX wave beam 1-RX wave beams 1, TX wave beam 1-RX wave beams 2, TX wave beam 1-RX wave beams 3, TX wave beam 1-RX wave beams 4；

TX wave beam 2-RX wave beams 1, TX wave beam 2-RX wave beams 2, TX wave beam 2-RX wave beams 3, TX wave beam 2-RX wave beams 4；

TX wave beam 3-RX wave beams 1, TX wave beam 3-RX wave beams 2, TX wave beam 3-RX wave beams 3, TX wave beam 3-RX wave beams 4；

TX wave beam 4-RX wave beams 1, TX wave beam 4-RX wave beams 2, TX wave beam 4-RX wave beams 3, TX wave beam 4-RX wave beams 4]

Each of matrix value is a transmitting and receiving wave beam pair.Disturbed gNB obtains each wave beam to corresponding Channel/interference matrix, then each wave beam to serial number and corresponding channel/interference condition feedback to gNB1.Optionally, only Interfering maximum one or several wave beams to serial number or interfering beam serial number and/or corresponding channel/interference shape oneself Condition is sent to gNB1.

Here, suppose that across the link interference relationship between gNB1DL and gNB2UL is：RX of the TX wave beams 1 of gNB1 to gNB2 Wave beam 1, which receives, influences maximum.GNB1TX wave beams 1 constitute an interfering beam pair with gNB2RX wave beams 1.GNB2 is TX wave beams 1- The serial number (and/or channel conditions) of 1 interfering beam pair of RX wave beams or only (and/or the channel of interfering beam serial number TX wave beams 1 Situation) it is sent to gNB1.

Other processes similar to example one, interfere need between gNB and disturbed gNB by return link (backhaul, such as X2 interface) or at least one the following information of (such as OTA signalings) interaction of eating dishes without rice or wine：Reference signal sends configuration information, gNB measurements are matched Confidence ceases.Further, on the basis of example one, it further includes sending gNB (interference gNB) that reference signal, which sends configuration information, Wave beam serial number (wave beam ID) or wave beam serial number and corresponding reference signal send configuration information.

Measurement result information is indicated to interference gNB by disturbed gNB.Further, on the basis of example one, knot is measured Fruit information further includes wave beam serial number/wave beam to serial number and corresponding measurement result information, alternatively, disturbed gNB is to oneself Maximum one or more wave beam serial number/wave beams are interfered to feed back to interference gNB to serial number.

Step 2: the interfering beam determined according to step 1 interferes base to serial number and/or corresponding channel/interference situation It stands and disturbed base station executes across link interference coordination.

The transmission of downlink in gNB1TX wave beams 1 and gNB2RX wave beams 1/uplink is limited or is coordinated, including it is following at least One of：

B. interference gNB is mapped in target downlink signal/channel in the kernel of interference channel when dispatching DL transmissions. The interference channel can be measured by being disturbed gNB by the RS that the reception of RX wave beams 1 is sent in TX wave beams 1, then be fed back to dry Disturb gNB；Alternatively, sending RS by disturbed gNB, interference gNB measures a channel, then obtains the interference according to channel heterogeneite Matrix；

C. the DL power in TX wave beams 1 is reduced.It reduces and the UL of gNB2 is interfered.

D. scheduling or transmission information of the gNB2 in RX wave beams 1 are received, direction is sent with the DL/UL of gNB2 and is aligned. When gNB2 sends DL in RX wave beams 1, gNB1 just can send DL in TX wave beams 1.When gNB2 dispatches UL in RX wave beams 1 When, gNB1 also can only dispatch UL in TX wave beams 1.Here TX wave beams/RX wave beams do not represent and send and receive direction.Only indicate wave The expanded angle of valve width or lobe.

When e.gNB1 has downlink transmission in TX wave beams 1, gNB2 is notified, dispatching uplink is not sent gNB2 in RX wave beams 1.

F., priority can be set, and the DL in gNB1TX wave beams 1 is high priority；Or ULs of the gNB2 in RX wave beams 1 For high priority.For example, when 1 priority of TX wave beams is higher, when there are the DL in gNB1TX wave beams 1, then gNB2 is in RX wave beams 1 In UL cannot send/receive, or normal transmitting-receiving (but interference of the DL to oneself UL can be faced at this time).Conversely, when existing UL in gNB2RX wave beams 1, then DLs of the gNB1 in TX wave beams 1 cannot send.

G. DL can be just configured in this TX wave beam 1 with longer cycle/interval to send.For example, by using TDD Configuration 0。

I. be disturbed gNB when dispatch UL send when, if at this time exist interference gNB in RX wave beams 1 UL receive across chain Road is interfered, and one of following method can be taken：UE UL transmissions under disturbed gNB can be lifted power, delay is sent, is changed MCS, change transmission carrier wave, cancellation transmission etc..And/or

Interfere gNB when dispatching DL transmissions, if there is interference gNB TX wave beams 1 at this time to being disturbed gNB RX wave beams 1UL receive across link interference, one of following method can be taken：The DL transmissions of interference gNB can reduce power, delay hair Give, change MCS, change transmission carrier wave, cancel transmission etc..

9th example：

Base station is measured when carrying out across link interference measurement, resource will be measured or measurement pattern notifies to give its subordinate UE.Such as When fruit subordinate UE has uplink transmission, rate adaptation operating can be executed, such as resource is punched or in these measurement resources or survey Not mapping uplink signal or data on spirogram sample.In order to avoid influencing measurement base station measurement.

For example, CSI-RS is used for across link interference measurement, as CSI measurements or RRM measure.Base station is measured in ZP CSI-RS Before carrying out interference measurement on (Zero-Power CSI-RS), the configuration of ZP CSI-RS resource or pattern need to notify to UE.UE When UL is sent, in ZP CSI-RS resource or pattern not maps UL signal or data or execute resource punch operation.

Tenth example：

UE is measured when carrying out across link interference measurement, the base station measures resource or measure pattern in UE executes rate Matching operation, such as resource punch or do not map downlink signal or data in these measurement resources or measurement pattern.

For example, SRS is used for across link interference measurement, as CSI measurements or RRM measure.UE own base stations are measured in ZP SRS DL signals or data are not mapped on (Zero-Power SRS), or execute punch operation.

11st example：

Transmitting terminal is perceived or is measured, and can have hidden node problem.Such as transmitting terminal is perceived or is measured, the result is that not It in the presence of across link interference, but once sends, but exists in receiving side stronger across link interference, this when will influence property Energy.

Solution is to be carried out across link interference perception by receiving terminal or measured.If receiving terminal is UE, UE is carried out across chain Road interference perception measures, and result is reported to gNB.If receiving terminal is gNB, gNB adjusts scheduling or resource according to result Distribution executes interference elimination/coordination system.

12nd example：

As above analysis, dynamic TDD (or being the scenes such as flexibly duplex, duplexing flexibility, full duplex) exist dry across link Disturb problem.It can be solved by interference cancellation mechanisms across link interference, interference coordination mechanism such as measures perception, cooperative beam is assigned Shape/cooperative scheduling, the design of orthogonal uplink and downlink signals etc..But due to the timing offset problem existing for the link, target UL/DL connects It receives and interference DL/UL has that timing is misaligned between link, the robustness for causing interference with the coordination system declines, Jin Erying Ring the performance to similar systems such as dynamic TDD.

Solution is as follows：

Introduce a kind of new measurement amount：Across link timing offset is measured for the timing offset between link.

Further, base station is inclined by across the link timing obtained between adjacent base station across the measurement of link timing offset Difference.And/or UE across the measurement of link timing offset by obtaining across the link timing offset between neighbour UE.

Further, a kind of new timing advance signaling word is introduced：Across link timing advance order (CLI-TA, cross Link interference-timing advance), it is fixed across link to carry out for carrying the information across link timing offset When be aligned, to solving the problems, such as across link synchronization.Base station indicates that UE adjusts uplink transmission timing or base station by CLI-TA The downlink transmission timing of itself is adjusted according to CLI-TA

Specifically, across the link timing offset for the sides UE measures：

It can one of as follows or the combinations of multiple steps solves the problems, such as this.

Step 1：Base station configures and/or instruction UE executes across link timing offset and measures.

The information that configuration/instruction UE executes across link timing offset measurement can pass through RRC signaling or DCI or MAC RE To carry.It is preferred that being measured by RRC signaling or DCI to indicate that UE executes across link timing offset.

It is periodically measured for example, can indicate that UE is executed by RRC signaling.Alternatively, can indicate that UE is held by DCI The aperiodic measurement of row.

Configuration may include the sub-frame configuration that across link timing offset measures or time slot configuration or running time-frequency resource configuration or Pattern configuration or period/offset/duration etc..

Preferably, base station can configure UE when carrying out CLI RRM or CLI CSI measurements, be carried out at the same time across link timing Deviation measures.Such as UE carries out across link timing offset in ZP-SRS resources and measures.ZP-SRS resources of the adjacent UE in the UE Upper transmission SRS.

Across the link timing offset variation of the sides UE is violent compared with base station side.Therefore, across the link timing offset of opposite base station side Measure or traditional LTE in Timing measurement, interval of the sides UE between across link timing offset measures twice wants short.Therefore, may be used To configure, short-period across link timing offset measures or aperiodic across link timing offset measures.

Particularly, base station according to the positions in the cell UE, and/or, UE receptivities such as BLER/SINR/CLI/RRM/ CSI dynamically to indicate that particular UE executes across link interference measurement.For example, being interfered especially for cell edge UE or CLI Larger UE, base station should indicate that it executes across link timing offset and measures.For center of housing estate UE, can not indicate, or compared with Once across link timing offset measures for long period instruction.

Step 2：UE executes across link timing offset and measures, and will be reported to across the measurement result of link timing offset Base station.

For UE according to across the link timing offset measuring configuration of base station or instruction, across the link timing executed between neighbour UE is inclined Difference measurements.

Preferably, UE can be carried out at the same time across link timing offset and measure when carrying out CLI RRM or CLI CSI measurements. Such as UE carries out across link timing offset in ZP-SRS resources and measures.Adjacent UE sends SRS in the ZP-SRS resources of the UE.

UE will be reported to base station across the measurement result of link timing offset, can be reported by following form：Exact value, base Multiple (such as the X, unit 16Ts of the multiple of this chronomere, basic time unit's multiple.Ts is basic time unit), across The quantification gradation of link timing offset.

Step 3：Across the link timing offset measurement result that base station is reported according to UE generates across link synchronization operation strategy. Such as：It executes across link timing alignment or does not adjust across link timing alignment.Further, there is following operation：

Scheme one：Base station adjusts the DL timings of oneself according to across link timing offset measurement result.For example, can shift to an earlier date For the downlink transmission timing of the UE.

Scheme two：Base station notifies across link timing offset measurement result to the base station of the neighbour UE.

For scheme two, advice method can be return link (backhaul, such as X2 interface or privately owned interface) or eat dishes without rice or wine (such as OTA signalings).Across link timing offset measurement result can be notified to adjacent base station by following form：It is exact value, basic Multiple (such as the X, unit 16Ts of the multiple of chronomere, basic time unit's multiple.Ts is basic time unit), across chain The quantification gradation of road timing offset.

For scheme two, further, the base station of the neighbour UE generates across link timing advance order CLI-TA, will It is notified to the neighbour UE.Such as pass through DCI or MAC CE.Preferably, across link timing advance life is carried by MAC CE Enable CLI-TA.Further, the neighbour UE adjusts the uplink transmission timing of oneself according to the CLI-TA received.

Specifically, across the link timing offset for base station side measures：

Step 1：It configures base station and executes across link timing offset measurement.

Preferably, base station can be carried out at the same time across link timing offset and survey when carrying out CLI RRM or CLI CSI measurements Amount.It is measured for example, base station carries out across link timing offset in ZP-CSI-RS resources.ZP-CSI- of the adjacent base station in the base station CSI-RS is sent in RS resources.Alternatively, base station executes across link timing offset and measures when receiving adjacent base station transmission CSI-RS, It does not require whether this base station configures ZP CSI-RS resource.

It can be periodic or acyclic that base station, which is executed with the measurement of across the link timing offset of adjacent base station,.

Since the position of two base stations immobilizes, across the link timing offset variation of base station side is stablized compared with the sides UE.Therefore, Across the link timing offset of the opposite sides UE measures, and the interval between base station side across link timing offset measurement twice will be grown.Therefore, Macrocyclic across link timing offset measurement can be configured or the long period just triggers primary aperiodic across link timing offset and surveys Amount.

Particularly, base station is carried out dynamic trigger and is done across link according to UL receptivities such as BLER/SINR/CLI/RRM/CSI Disturb measurement.For example, base station UL receptivities are poor or CLI interference is larger, it is more than setting threshold value, base station triggers execute non- Period, across link timing offset measured.

Step 2：Across the link timing offset measurement result in base station generates across link synchronization operation strategy.Such as：Execute across Link timing is aligned or does not adjust across link timing alignment.Further, there is following operation：

Scheme one：Base station generates across link timing advance order CLI-TA according to across link timing offset measurement result, will It is notified to affiliated UE.Such as pass through DCI or MAC CE.Preferably, across link timing advance order is carried by MAC CE CLI-TA.Further, the UE adjusts the uplink transmission timing of oneself according to the CLI-TA received.For example, delay is across chain Road timing offset chronomere sends UL.

Scheme two：Base station notifies across link timing offset measurement result to the adjacent base station.

For scheme two, further, the adjacent base station is according to across the link timing offset received as a result, adjusting oneself Downlink transmission timing.For example, across the link timing offset chronomere can be shifted to an earlier date with downlink transmission timing.
