Compared to LTE system, 5G NR system will have wider array of spectral range (within GHz).Since signal is located at high frequency Range, compared to low frequency signal by by bigger path loss and signal fadeout, signal intensity also can more acutely.It is based on This, NR system is by using extensive multiple-input, multiple-output (multiple-input-multiple-output, MIMO) and multi-beam (multi-beam) technology may be implemented signal and concentrate in a direction transmitting, enhances the anti-fading ability of signal.This Also for wireless backhaul technology use and deployment creates condition.Wireless backhaul technology between base station by establishing based on wave beam Radio Link carries out data, signalling, network erection and lower deployment cost can be reduced, for the 5th third-generation mobile communication technology (5thGeneration, 5G) in the scenes such as dense deployment, indoor transmissions for, be of great significance.Access passback integration Technology can share band resource by access link and return link, dispose with frequency, and can promote frequency spectrum utilizes effect Rate.
Due to being needed in high frequency using wave beam, (new radio, NR) system of newly eating dishes without rice or wine introduces the general of wave beam management It reads.Wave beam management refers to base station and user side to the system obtained and management is transmitted and received for user's downlink and uplink wave beam Column operating process, including the measurement of beam selection, wave beam, wave beam report and the parts such as beam scanning.Wave beam management is based on a series of Reference signal progress, base station or user, using the different wave beams that sends or receives, realize for wave beam in these reference signals Scanning.User or base station are measured based on the wave beam of scanning, the selection course of further progress wave beam and the knot by selection Fruit is fed back.
In the discussion and conclusion of current NR, the wave beam management process of upstream or downstream is only related to, and independently carry out It discusses.However in IAB scene, relaying transmitting-receiving node is configurable to send to base station and terminal simultaneously, i.e. relaying transmitting-receiving section Point while the transmission for carrying out return link uplink and access link downlink.Due to also needing to carry out wave beam management under IAB scene Process needs to match respectively for the wave beam management of uplink and downlink if independently carrying out the wave beam management of uplink and downlink Set corresponding reference signal resource, it will cause the waste of running time-frequency resource.Meanwhile if independent wave beam management process is not same Shi Jinhang also will cause the deadline of wave beam management to lag.Further, since not accounting for return link and access link simultaneously The influence of transmission, the wave beam that base station and terminal are selected after independent beam management may be mutually of interference, to biography later It is defeated to affect.
The application provides a kind of wave beam management method, to solve relaying transmitting-receiving node in IAB scene independently into Possible extra resource expense when the wave beam of row access link and return link manages, wave beam management time delay is longer etc. to ask Topic.Compared with prior art, united beam management method provided by the present application can efficiently use shared reference signal resource and Wave beam completes the wave beam management on return link and access link, can reduce the overall delay of resource overhead and wave beam management.Such as Shown in Fig. 2, the application provides a kind of wave beam management method, mainly includes the following steps:
Step 101, relaying transmitting-receiving node determines first resource group and Secondary resource group, the resource in the first resource group Unit is for carrying out the measurement and selection of wave beam in the first wave beam group between the relaying transmitting-receiving node and terminal, and described second Resource unit in resource group is for carrying out the measurement of the wave beam in the second wave beam group between the relaying transmitting-receiving node and base station And selection.
Wherein, the wave beam in the first wave beam group described in step 101 is that the relaying transmitting-receiving node configures for access link Management wave beam, the wave beam in the second wave beam group is the management wave beam that the relaying transmitting-receiving node is return link configuration.
It should be noted that for a relaying transmitting-receiving node, superior node is base station in IAB scene, Downstream site is terminal, relays and is connected between transmitting-receiving node and base station by return link, is relayed between transmitting-receiving node and terminal It is connected by access link.When relaying wave beam progress corporate management of the transmitting-receiving node to access link and return link, relaying Transmitting-receiving node is equal to downlink wave beam management, wave beam pipe of the relaying transmitting-receiving node to return link to the wave beam management of access link Reason is equal to uplink beam management, and for ease of description, in the application, relaying transmitting-receiving node is sent by return link to base station Wave beam be uplink beam, the wave beam sent to terminal by access link is downlink wave beam.
Step 102, resource unit and the first wave that the relaying transmitting-receiving node includes according to the first resource group The corresponding relationship of the wave beam of Shu Zuzhong sends the wave beam in the first wave beam group.Correspondingly, terminal is connect using first resource group Receive the wave beam in the first wave beam group from relaying transmitting-receiving node.
Step 103, resource unit and second wave that the relaying transmitting-receiving node includes according to the Secondary resource group The corresponding relationship of the wave beam of Shu Zuzhong sends the wave beam in the second wave beam group；Wherein, when the first resource group includes There are when identical resource unit, the relaying transmitting-receiving node exists the resource unit that resource unit and the Secondary resource group include The wave beam sent on the identical resource unit is the shared wave beam of the access link and the return link.Correspondingly, Base station receives the wave beam in the second wave beam group from relaying transmitting-receiving node using Secondary resource group.
Step 102 and step 103 do not have strict sequence, the resource unit for including when the first resource group and institute Resource unit that Secondary resource group includes is stated there are when identical resource unit, identical resource list in step 102 and step 103 The transmission of shared wave beam in member is simultaneous.
Wherein, first resource group includes one or more resource units, and Secondary resource group includes one or more resource lists Member, first resource group and Secondary resource group may exist common source, and common source can also be not present.In the wave beam of not homogeneous In scanning, first resource group and Secondary resource group be may be the same or different.
The resource unit that the resource unit and the Secondary resource group for wherein including when the first resource group include exists When identical resource unit, identical resource unit includes one or more resource units, and identical resource unit refers to first The resource unit that resource group and Secondary resource group are overlapped in time-frequency domain resources, resource unit can be for shared by one wave beams of transmission Running time-frequency resource.
Wherein, relaying transmitting-receiving node is sent multiple in the first wave beam group using multiple resource units in first resource group Downlink wave beam.It relays transmitting-receiving node and uses multiple uplinks in multiple resource units the second wave beam group of transmission in Secondary resource group Wave beam.There are identical moneys for the resource unit that the resource unit and the Secondary resource group for including when the first resource group include When source unit, multiple uplink beams in the multiple downlink wave beams and the second wave beam group in the first wave beam group exist Identical wave beam shares wave beam, the resource unit for sending shared wave beam is properly termed as common source unit.
For example, Secondary resource group includes 4 resource units as shown in figure 3, first resource group includes 4 resource units, the One resource group and Secondary resource group include two common source units, and relaying transmitting-receiving node uses 4 resources of first resource group Unit transmission downlink wave beam 1, wave beam 2, wave beam 3, wave beam 4, relaying transmitting-receiving node are sent out using 4 resource units of Secondary resource group Uplink beam 3 is sent, wave beam 4, wave beam 5, wave beam 6, then wave beam 3 and wave beam 4 are to share wave beam, it can be understood as relaying transmitting-receiving node Wave beam 3 and wave beam 4 are sent to terminal and base station simultaneously.
Downlink wave beam in first wave beam group can be sent by the reference signal on access link, in the second wave beam group Uplink beam can be sent by the reference signal on return link, so first resource group can be the downlink in access link Reference signal resource, Secondary resource group can be the ascending reference signal resource in return link.
In a kind of possible design, relaying transmitting-receiving node described in step 101 determines first resource group and Secondary resource Group, comprising:
The relaying transmitting-receiving node determines the first reference signal resource according to the second reference signal resource, so that described first Reference signal resource partly overlaps with second reference signal resource, and the relaying transmitting-receiving node is provided according to the first reference signal Source determines the first resource group, determines the Secondary resource group, the first resource group packet according to the second reference signal resource It is contained in first reference signal resource, the Secondary resource group is included in second reference signal resource.
Wherein, first reference signal resource is that the relaying transmitting-receiving node configures for the terminal, for accessing The wave beam management of link.Second reference signal resource is that the base station configures for the relaying transmitting-receiving node, is used for back Pass the wave beam management of link.
Optionally, the first reference signal resource and the second reference signal resource can be period, aperiodic or semi-continuous match It sets.
First reference signal resource partly overlaps with second reference signal resource, and meaning refers to the first reference Signal resource can be multiplexed with second reference signal resource, i.e., the reference signal on return link in time-frequency domain resources with The reference signal of access link has intersection in time-frequency domain resources, and when the first reference signal resource and second is with reference to letter When number resource is period assignment, period that the period that the first reference signal resource has can have with the second reference signal resource It is identical.
Optionally, the reference signal on return link can be specific reference signal on return link, such as detection reference Signal (sounding reference signal, SRS).Reference signal on access link can specifically refer to for user Signal, such as synchronous block (synchronization signal block, SSB) or channel state information reference signals (channel state information-RS,CSI-RS)。
Based on above method process, shared reference signal resource and shared wave beam can be efficiently used, complete passback and Wave beam management on access link can reduce the overall delay of resource overhead and wave beam management
Based on above-mentioned steps 101 to step 103, when relaying transmitting-receiving node carries out the joint wave of return link and access link When beam tube is managed, if needed for the wave beam management of ascending reference signal resource needed for the wave beam management of return link and access link Downlink reference signal resource there are in time-frequency domain resources some be overlapped, relaying transmitting-receiving node can efficiently use it is shared Reference signal resource and wave beam complete a part of wave beam management on passback and access link, are conducive to reduce this subwave beam tube The resource overhead of reason and and be conducive to reduce the overall delay of entire wave beam management process.
In addition, when relaying transmitting-receiving node independently carries out wave beam management to return link and access link, due to not examining The influence for considering return link and access link simultaneous transmission causes the wave beam that base station and terminal are selected after independent beam management can It can be mutually of interference, transmission later is affected.The above-mentioned united beam management method of the application, due to upgoing wave The reference signal resource of beam and downlink wave beam is by relaying transmitting-receiving node corporate management, therefore, during corporate management, just It can guarantee that wave beam selected by base station and terminal will not interact, therefore even if return link and access link simultaneous transmission, Wave beam selected by base station and terminal will not interact.
But when relaying wave beam progress corporate management of the transmitting-receiving node to access link and return link, on return link Beam power may be consistent, the beam power on access link may be inconsistent, this can bring terminal based on the wave measured The larger problem of the error of beam reception power progress beam selection.In the application, relaying transmitting-receiving node can be sent out to terminal in advance The power offset values of the wave beam on access link are sent, and then are solved using wave beam when sharing wave beam on bring access link Send the inconsistent bring above problem of power.
In a kind of possible design, before step 102, relaying transmitting-receiving node generates one for the downlink wave beam sent Group power offset values, and the power offset values of each wave beam are informed into terminal, specifically, comprising: the relaying transmitting-receiving node Determine in the first resource group each associated function of wave beam in each corresponding wave beam of resource unit and the first wave beam group Rate deviant；The relaying transmitting-receiving node is according to the corresponding wave beam of resource unit each in the first resource group and described Each associated power offset values of wave beam determine each associated power offset values of resource unit in the first resource group；
The relaying transmitting-receiving node sends each associated power of resource unit in the first resource group to the terminal Deviant.
In the embodiment of the present application, when uplink beam and downlink wave beam, which exist, shares wave beam, wave beam is shared in downlink wave beam The inconsistent problem of power is sent with what non-common wave beam was likely encountered, in order to avoid sending power in downlink wave beam to terminal The accuracy of wave beam measurement has an impact, and the embodiment of the present application generates one before each beam scanning, to each downlink wave beam Group power offset values, and the power offset values of each downlink wave beam are informed into terminal, so that terminal is by using power offset values Beam quality is calculated again after compensating to the actual transmission power of each downlink wave beam, it can be in the downlink wave beam of access link In the case where with different transmission power, the accuracy of terminal beams measurement is not still influenced.
It should be noted that wave beam management of the relaying transmitting-receiving node to access link, refers to relaying transmitting-receiving node and terminal Between multiple beam scanning and report process, by a series of reference signal resources use different transmission/receptions Wave beam realizes that this process can be repeated, and continues for some time, so that it is determined that optimal out use wave beam.Under primary The beginning of traveling wave beam scanning process can be relaying transmitting-receiving node triggering, such as when the uplink beam scanning process on return link After base station triggers, relaying transmitting-receiving node can be after the uplink beam scanning that is triggered, and the wave beam triggered on access link is swept Retouch process.It can also be configured periodic triggers.The duration of beam scanning process is the effective of primary aperiodic triggering Time or the effective time of period triggering.Before beam scanning each time, relaying transmitting-receiving node will determine each be activated Resource unit corresponding to power offset values, until relaying transmitting-receiving node notice base station and terminal send wave beam no longer change Become.
Optionally, the relaying transmitting-receiving node determines the corresponding power offset values of each wave beam in the first wave beam group, It include: the transmission power that the relaying transmitting-receiving node determines each wave beam in the first wave beam group；The relaying transmitting-receiving node According to the transmission power of one of wave beam in the first wave beam group, the function of each wave beam in the first wave beam group is determined Rate deviant.
Specifically, can be in determining the first wave beam group after the transmission power of each downlink wave beam, by one of them Transmission power level is as benchmark, deviation between transmission power and benchmark based on each downlink wave beam in the first wave beam group, Calculate the power offset values of each downlink wave beam in the first wave beam group.
If the wave beam in the first wave beam group can be divided into shared wave beam and non-common wave beam, the transmitting function of wave beam is shared Rate can be consistent with the transmission power of uplink beam, and the transmission power for sharing wave beam and non-common wave beam can be inconsistent, non-total Can be consistent with the transmission power of wave beam, it can also be inconsistent.The power offset values of wave beam in first wave beam group are received by relaying It sends out node and (such as being generated based on path loss) is generated based on the channel measurement of upstream or downstream.
It optionally, can be using the transmission power of a non-common wave beam as benchmark, or by the hair of a shared wave beam Power is penetrated as benchmark, or using a preset fixed value as benchmark, which, which can be, is different from sharing wave beam The transmission power of transmission power and non-common wave beam.
Optionally, relaying transmitting-receiving node determines the corresponding power offset values of each resource unit in the first resource group, Establish the pass between multiple resource units in first resource group and the power offset values of multiple wave beams in the first wave beam group Connection relationship.Before triggering wave beam management, relaying transmitting-receiving node establishes multiple resource units and first wave in first resource group Incidence relation between the power offset values of multiple wave beams of Shu Zuzhong, and then each power offset values and a downlink are joined Examining signal resource is associated, so that the wave beam using this downlink reference signal resource will be preset in one of relaying transmitting-receiving node Transmission power on the basis of carry out corresponding power excursion, so as to terminal according to the power offset values of these wave beams carry out wave beam Measurement.
So relaying transmitting-receiving node determines the corresponding power offset values of each resource unit in the first resource group, this Process can be relaying transmitting-receiving node and carry out what first time beam scanning triggered before, at this point, first resource group is relaying transmitting-receiving Node will carry out the downlink reference signal resource used needed for first time beam scanning, and the wave beam in the first wave beam group is relaying Transmitting-receiving node will carry out the required downlink wave beam used when first time beam scanning.Or this process is also possible to relaying transmitting-receiving It is inclined to the corresponding power of downlink reference signal resource used needed for beam scanning next time after node completes a beam scanning What shifting value triggered when being updated, at this point, first resource group is that relaying transmitting-receiving node will carry out needed for beam scanning next time The downlink reference signal resource used, the wave beam in the first wave beam group are that relaying transmitting-receiving node will carry out beam scanning next time The downlink wave beam that Shi Suoxu is used.Beam scanning of the every completion of transmitting-receiving node is relayed, last wave will be directed to according to terminal The feedback that beam scanning is sent calculates in beam scanning next time, and wave beam is sent used by relaying transmitting-receiving node and its is answered The power situation of the use, and further determine that the power offset values used needed for each wave beam, and by the power offset values with Each corresponding downlink reference signal resource of wave beam is associated.
It should be noted that for the downlink reference signal resource used that is not activated in the first reference signal resource, Power offset values can not be associated with, or do not notify the corresponding power offset values of its history.
Wherein, the relaying transmitting-receiving node determines the corresponding wave beam of each resource unit in the first resource group, Specifically:
The relaying transmitting-receiving node after determining first resource group and determining multiple wave beams in the first wave beam group, Relaying transmitting-receiving node configure multiple resource units in the first resource group and multiple wave beams in the first wave beam group it Between corresponding relationship.

In a kind of possible design, the terminal is according to the corresponding power of resource unit each in the first resource group Deviant selects one or more wave beams from the first wave beam group, comprising: the terminal obtains the first resource group In each resource unit Reference Signal Received Power；For the first resource unit in the first resource group, described first Resource unit is any resource unit in the first resource group, and the terminal is according to the associated function of first resource unit Rate deviant is corrected the Reference Signal Received Power of the first resource unit, obtains the first resource list The equivalent Reference Signal Received Power of member；The terminal is according to the equivalent ginseng of each resource unit in the first resource group Signal reception power is examined, selects one or more wave beams from the first wave beam group.
Every time after the beam scanning process of relaying transmitting-receiving node, it is preferable that terminal can feed back one or more beam qualities The index of reference signal resource give relaying transmitting-receiving node, so as to relay transmitting-receiving node can be come according to the feedback information of terminal it is true Wave beam when fixing a beam scanning in the first wave beam group.Specifically, when completing wave on user equipment downlink reference signal resource After beam measurement, one or a set of reference signal resource is selected, the index number of corresponding reference signal resource is fed back into relaying and is received Send out node.Selected principle can be based on the Reference Signal Received Power (RS measured on each reference signal resource receiving power,RSRP).Terminal corresponding power of reference signal resource used in each downlink wave beam of acquisition is inclined It, can be on the basis for the RSRP that actual measurement arrives, in addition corresponding power offset values, calculate reference letter after shifting value Equivalent RSRP in number resource, and then guarantee the accuracy of wave beam measurement.
In a kind of possible design, the terminal is received in the first resource group from the relaying transmitting-receiving node The corresponding power offset values of each resource unit, comprising: the terminal receives the first instruction from the relaying transmitting-receiving node Information, the first instruction information includes N number of indication field, and N number of indication field is used to indicate N number of power offset values, institute The indication field for stating the corresponding power offset values of each resource unit in first resource group is included in N number of indication field； Wherein, the resource unit in the first resource group is included in N number of resource unit that first reference signal resource is pre-configured In subset, name placement of the N number of indication field in the first instruction information is pre- with first reference signal resource For the name placement of N number of resource unit subsets of configuration there are one-to-one relationship, N is the positive integer greater than 1.In this way, by pre- The incidence relation for first binding the indication field of subset and deviant, does not need the explicit corresponding downlink of each wave beam of informing terminal What reference signal resource and the corresponding power offset values size of each downlink reference signal resource be, it is only necessary to tell end The power offset values of the downlink reference signal resource of which position in N number of subset are held to need to update, and the power excursion updated It is worth size, only needs N number of indication field that can notify above-mentioned incidence relation in this way, is conducive to save signaling overheads.
In a kind of possible design, the terminal is received in the first resource group from the relaying transmitting-receiving node The corresponding power offset values of each resource unit, comprising: the terminal receives the second instruction from the relaying transmitting-receiving node Information, the second indication information are used to indicate the position rope of each resource unit in the first resource group to the terminal Draw power offset values corresponding with the location index；Wherein, the second indication information is carried believes in radio resource control RRC In order, perhaps carries in MAC-CE signaling or carry in DCI signaling.
For base station side, when relaying transmitting-receiving node sends upgoing wave to base station on a series of reference signal resource Shu Shi, base station receive the transmission wave beam from relaying transmitting-receiving node on a series of reference signal resources.Specifically, comprising: Base station determines Secondary resource group, and base station receives the wave in the second wave beam group from relaying transmitting-receiving node using Secondary resource group Beam, the resource unit in the Secondary resource group is for carrying out the measurement and choosing of wave beam between the relaying transmitting-receiving node and terminal It selects.Base station carries out the measurement and selection of transmission wave beam relaying during the beam scanning of transmitting-receiving node triggering, base station is used Secondary resource group in multiple resource units and institute received second wave beam group in multiple wave beams one-to-one correspondence.Wherein, institute Secondary resource group is stated in the second reference signal resource, second reference signal resource is used for the wave beam pipe of return link Reason.Since first resource group is included in the first reference signal resource, base station can be in the first reference signal resource position It is monitored to obtain the occupied Secondary resource group of wave beam in relaying transmitting-receiving node the second wave beam group of transmission.In some possibility Embodiment in, can also from relaying transmitting-receiving node to base station feedback relaying transmitting-receiving node send the second wave beam group in wave beam Occupied Secondary resource group.
For base station, following methods process is also executed in the wave beam management method process of relaying transmitting-receiving node:
In a kind of possible design, the base station using Secondary resource group receive from relaying transmitting-receiving node second Before wave beam in wave beam group, the method also includes: the base station sends the second index information to the relaying transmitting-receiving node, Second index information include the base station it is upper wave beam measurement and selection are once carried out between relaying transmitting-receiving node when from The location index of resource unit corresponding to the one or more wave beams selected in the management wave beam having received, so as to described Transmitting-receiving node beam information according to corresponding to second index information is relayed, determines multiple waves in the second wave beam group Beam.Optionally, the second index information can be carried physically shared channel (the physical downlink of row by base station Shared channel, PUSCH) or Physical Uplink Control Channel (physical downlink control channel, PUCCH relaying transmitting-receiving node is sent in).
In a kind of possible design, the method also includes: the base station obtains each money in the Secondary resource group The Reference Signal Received Power of source unit；The base station is according to the Reference Signal Received Power, from the second wave beam group One or more wave beams are selected, and send base station selected one or more wave beam institutes out to the relaying transmitting-receiving node The location index of corresponding resource unit.Every time after the beam scanning process of relaying transmitting-receiving node, base station can feed back one Or the index of multiple preferable reference signal resources of beam quality gives relaying transmitting-receiving node, to relay transmitting-receiving node according to base station Feedback information come the transmission power of wave beam and each wave beam when determining beam scanning next time in the second wave beam group.Specifically For, after measurement is completed in base station on ascending reference signal resource, one or a set of reference signal resource is selected, will accordingly be joined The index number for examining signal resource feeds back to relaying transmitting-receiving node.Selected principle can be based on each reference signal resource Measure obtained RSRP.
Based on above method process, there is different transmission power with the wave beam of downlink access link, uplink return link For there is wave beam equal-wattage, the wave beam of downlink access link and the wave beam of uplink return link to have shared wave beam, this Shen Please embodiment a kind of method flow of wave beam management method is provided, as shown in figure 4, mainly comprising the steps that
Step 1: relaying transmitting-receiving node is the reference signal for relaying one group of return link of transmitting-receiving node configuration according to base station Resource configures the reference signal resource of a group of access link for terminal.
Wherein, configuration mode has the following two kinds situation:
The first situation: if the bandwidth of return link is less than or equal to the bandwidth of access link, the reference of access link Signal resource includes the reference signal resource of return link.
Second situation: if the band of return link is wider than the bandwidth of access link, the reference signal of access link Resource is contained in the reference signal resource of return link.
Step 2: relaying transmitting-receiving node activates the reference signal resource of a part of return link for uplink beam management, swashs The reference signal resource of a part of access link living is used for downlink wave beam management, and for ease of description, activation is used for down going wave The reference signal resource of beam tube reason is first resource group, and the reference signal resource for uplink beam management of activation is the second money Source group.
Step 3: relaying transmitting-receiving node is that each reference signal resource configures a power offset values in first resource group, to The corresponding power offset values of each reference signal resource of terminal notification.
For example, first resource group includes N number of reference signal resource, for carrying N number of reference signal, N number of reference signal is used In transmitting N number of downlink wave beam, relaying transmitting-receiving node configures one group of power offset values { Δ P1,...,ΔPN), wherein N is is configured Power offset values number (can be the same or different between power offset values).Each power offset values and access link Reference signal resource set in a reference signal resource for access link it is associated, that is, use the reference signal The transmission wave beam of (reference signal, RS) resource will have corresponding power excursion.Meanwhile by each power offset values It is configured with the incidence relation of a reference signal resource for access link by RRC signaling, or logical by MAC CE signaling Know, informs terminal.
Step 4: relaying transmitting-receiving node scans the first wave beam group in the first resource group of access link, in return link The second wave beam group is scanned in Secondary resource group, at the same time, terminal scans the first wave beam in the first resource group of access link The second wave beam group is scanned in group, base station in the Secondary resource group of return link.Wherein, when first resource group and Secondary resource group have When having common source, the first wave beam group and the second wave beam group have shared wave beam, and relaying transmitting-receiving node scans on common source Share wave beam.
Wherein, it is identical with RS resource used on access link in return link to share wave beam, i.e. relaying transmitting-receiving node The access link RS resource of activation is in time-frequency domain and periodically upper identical as by the return link RS resource of base station activation.
After terminal receives the transmission wave beam of a relaying transmitting-receiving node, according to the corresponding access link RS resource of wave beam and Its corresponding power offset values calculates the equivalent Reference Signal Received Power of each reference signal (it can be appreciated that wave beam).
Its calculation isWhereinI-th of reference signal resource is measured for terminal Obtained equivalent Reference Signal Received Power, RSRPiI-th of reference signal resource measurement is obtained for terminal practical with reference to letter Number receive power, Δ PiFor the corresponding power offset values of i-th of reference signal resource.
After terminal is completed the wave beam measurement on access link and calculated, beam selection is carried out according to certain rule, is such as selected Then the equivalent maximum wave beam of RSRP feeds back corresponding reference signal resource index number to relaying transmitting-receiving node.It completes base station After wave beam measurement on return link, the reference signal resource index number of one return link of similar selection feeds back to relaying Transmitting-receiving node.
Step 5: after relaying transmitting-receiving node receives the feedback of base station and terminal, updating the wave beam and second in the first wave beam group Wave beam in wave beam group updates the corresponding power offset values of each reference signal resource.
For updated wave beam is needed, transmitting-receiving node is relayed by the power offset values of each updated wave beam and one The RS resource of a access link is associated, and by signaling each new power offset values of terminal and each access chain Incidence relation between the RS resource on road, the signaling can be RRC, MAC-CE or DCI signaling.
Wherein, the method for update is equivalent to each that its corresponding power of access link RS resource updates to be used is inclined Shifting value.In next beam scanning, if there is the shared wave beam with uplink beam, certain wave beams are relative to other downlink wave beams Power excursion is carried out, then these wave beams are used in corresponding RS resource.If the power of all downlink wave beams is all consistent (i.e. there is no the shared wave beams with uplink beam, and the power of all downlink wave beams can be the same at this time), then can by all wave beams So that in the RS resource that no associated power deviates or all wave beams can be used power excursion be 0 RS resource.
Step 6: judging that whether send uplink beam and downlink wave beam no longer changes, and if so then execute step 7, returns if not Step 3, repeat step 3 to 5 until relaying transmitting-receiving node no longer trigger transmission beam scanning until.
The beam scanning for wherein repeating step step 3 to 5 is real by the periodical appearance of RS resource or aperiodic activation It is existing.For example, being to open or close by configuring the domain repetition in RS resource IE, realization indicates whether that having carried out wave beam sweeps It retouches.
Step 7: relaying transmitting-receiving node signals base and terminal send wave beam and no longer change, such as are reconfigured using RRC signaling Or it is indicated using dynamic signaling.
For example, modification access link RS resource information element is reconfigured by RRC signaling in relaying transmitting-receiving node The domain (repetition) is repeated in (information element, IE) IE is " ON "；Request base station by return link RS simultaneously It is revised as in the domain repetition of resource " ON ".Its wave beam being meant that on each reference signal resource is identical wave Beam.
1 to step 7 through the above steps, and return link and access link may be implemented and use identical reference signal resource Wave beam management process is carried out with wave beam, improves the efficiency of wave beam management, resource overhead needed for saving wave beam management.Compared to return Link and the independent wave beam management process of access link are passed, passback and the united beam management of access link may be implemented.Simultaneously By using power offset values, wave still can not be influenced in the case where access link wave beam has different transmission power The accuracy of beam measurement.
As a kind of alternative, above-mentioned steps 2 be could alternatively be: is divided into the first reference signal resource reserved Part and non-reserved parts, mark off N number of subset for reserved part, this N number of subset is used for the wave beam management of access link, these Mutual exclusion between subset, i.e., no common portion, and notify terminal, i.e., each terminal to know each access the division result of subset Which subset is the RS resource of link belong to.The notice of subset division result can match with the RS resource of access link in step 1 Synchronous progress is set, i.e., at the end of the configuration of the RS resource of access link, the division of subset is had also determined that.
In above-mentioned steps 4, when terminal receives on the reference signal resource of some access link sends wave beam, according to Subset serial number and its corresponding power offset values belonging to reference signal resource, calculate equivalent RSRP.
Above-mentioned steps 5 can be replaced: after relaying transmitting-receiving node receives the feedback of base station and terminal, update in the first wave beam group Wave beam and the second wave beam group in wave beam, the corresponding power offset values of N number of subset are updated.
Based on step 4 measurement as a result, relaying transmitting-receiving node determines the power offset values of K (K is less than or equal to N) a wave beam It will change, then relay transmitting-receiving node and pass through the signalings such as RRC or MAC-CE or DCI for the power offset values of this K wave beam Notify to terminal, wherein K power offset values have it is certain put in order, each power offset values corresponding one divides in advance The RS subset of resources of access link, and the position arrangement and the RS resource of access link that each power offset values occur in the signaling The index number of subset has corresponding relationship.For example, in MAC-CE signaling, K power offset values in the signaling have one Fixed puts in order.In this way, appear in the power offset values of position 1, then with the RS subset of resources phase of the access link of serial number 1 Association.
In this alternative, may be implemented passback and access link using identical reference signal resource and wave beam into Traveling wave beam management process improves the efficiency of wave beam management, resource overhead needed for saving wave beam management.Pass through the side implicitly updated Formula is updated the incidence relation between power offset values and reference signal resource, being capable of saving signaling expense.
In another alternative, in step 5, according to the feedback of base station and terminal, the wave beam of next time is found When scanning process does not have common beam, the transmission power of downlink wave beam is identical during next beam scanning, without carrying out When the update of power offset values, a kind of mode is can still to update the corresponding power offset values of each reference signal resource, only It is that power offset values are updated to 0.Another way is to replace above-mentioned steps 2 are as follows: relaying transmitting-receiving node activates Secondary resource Group be used for uplink beam management, activation information resources group be used for downlink wave beam management, wherein Secondary resource group information resources group with Secondary resource group is without common source.
Above-mentioned steps 3 are saved, and above-mentioned steps 4 can be replaced: information resources of the relaying transmitting-receiving node in access link The first wave beam group is scanned in group, the second wave beam group is scanned in the Secondary resource group of return link, and at the same time, terminal is accessing The first wave beam group is scanned in the information resources group of link, the second wave beam group is scanned in base station in the Secondary resource group of return link. Wherein, the first wave beam group and the second wave beam group do not share wave beam.
Above-mentioned steps 5 can be replaced: after relaying transmitting-receiving node receives the feedback of base station and terminal, update in the first wave beam group Wave beam and the second wave beam group in wave beam, adjust the first wave beam group in wave beam transmission power, adjust the second wave beam group in Each wave beam transmission power.Uplink and downlink wave beam management process in the non-IAB scene of step 5 at this time is similar.
This embodiment is not limited to only carry out occurring as soon as after a common beam scans do not have the case where common beam.Work as root When not having common beam according to feedback result discovery, it can start to execute above-mentioned interchangeable step 4 and step 5.
In above-mentioned alternate embodiment, it can make when not having the condition using common beam, united beam pipe Reason process can return back to independent upstream or downstream wave beam management process, can be compatible with the wave beam pipe of existing upstream or downstream Reason process executes.
