Background technique

High bandwidth is future wireless network, including 5G (5th generation mobile networks or 5th Generation wireless systems, 5G) wireless network newly eat dishes without rice or wine (New Radio, NR) development necessity. Since low-frequency range (such as below 6GHz frequency range) bandwidth gradually exhausts, high band will become future wireless network and seek workable frequency Section selection.In current NR research, high band (such as 20-30GHz frequency range) is the important frequency range of its spread bandwidth.It therefore, can be with , it is envisioned that high band may will seem important in certain scenes with the increase of the following wireless bandwidth.Frequency electromagnetic waves have around The problems such as penetrating ability difference and serious propagation attenuation may cause partial region to occur because of environment, such as blocking for building Coverage hole.Therefore, the relay node (Relay Node, RN) of introducing enhancing covering becomes solution high frequency to solve blind area covering The important means of covering.But the deployment of relay node, if wired solving backhaul (Backhaul, BH) (again by traditional It is wireless backhaul, the application may not use with being distinguish) it is likely to result in that cost is excessively high, and operator is difficult to receive.Therefore, In view of the high bandwidth of future wireless network, NR considers to introduce integrated access and backhaul (Integrated Access and Backhaul, IAB) scheme to further decrease lower deployment cost, improves disposition flexibility, and thus introduces to have and access backhaul one The relaying of body, the application will access the integrated relay node of backhaul and be known as relay transmission receiving point (relay Transmission Reception Point, rTRP) to distinguish the relaying of LTE.Third generation partner program 3GPP (English Text: Third Generation Partnership Project；3GPP) RAN1 (English: radio access network working group 1；RAN1) 86 meetings determined NR IAB research project verification, study in junction network, backhaul link with Access the joint operation mechanism of (link), wherein the dynamic resource allocation of backhaul link and access link is that one of IAB is important Design object.

In LTE, by taking the downlink transfer of backhaul link as an example, the resource allocation of backhaul link is single with 10 milliseconds of radio frames Several sub-frame configurations in one radio frames are backhaul link subframe by bit period configuration, in backhaul link subframe, RN is by sending out Sending pattern switching is reception pattern, carries out backhaul link reception, RN just can not be to its subordinate's user equipment (User at this time Equipment, UE) carry out downlink transfer.To avoid subordinate UE from carrying out cell specific reference signal CRS (Cell- in this subframe Specific Reference Signal, CRS) operation, eNB and the RN such as detection be required to configure backhaul link subframe to more Media broadcast multicast service single frequency network MBSFN (Multimedia Broadcast multicast service Single Frequency Network, MBSFN) subframe.

In NR, access and backhaul use identical technology to will lead to backhaul with the variation of access user data rate The dynamic change of bandwidth can relatively frequently, and the configuration mode of the MBSFN of similar LTE makes the resource distribution of access link ineffective It is living.In addition, the synchronization signal block (Synchronization Signal block, SS block) in NR, partial channel-state Reference signal CSI-RS (Channel-state information reference signal, CSI-RS), track reference letter The downstream cycles signals such as number TRS (tracking reference signals, TRS) and local channel detect reference signal SRS (Sounding Reference Signal, SRS), Physical Uplink Control Channel PUCCH (Physical Uplink Control Channel, PUCCH) etc. upward cycles signal, these periodic signals usually to the maintenance of the link performance of UE have weight It acts on, and quickly cannot be reconfigured or be closed, if since access and the variation of backhaul link resource lead to access link It is clashed with backhaul link resource, will affect access link performance.Therefore, keeping backhaul link and the access link resource can Under the premise of flexible allocation, and it is avoided that the cyclical signal conflict of backhaul link and access link is a need in NR IAB It solves the problems, such as.

Fig. 1 is IAB communication system provided by the embodiments of the present application.

It should be noted that the communication system that the embodiment of the present application refers to includes but is not limited to: narrowband Internet of things system (English Text: Narrow Band-Internet of Things, referred to as: NB-IoT), global system for mobile communications (English: Global System for Mobile Communications, referred to as: GSM), enhanced data rates for gsm evolution system (English: Enhanced Data rate for GSM Evolution, referred to as: EDGE), broadband CDMA system (English: Wideband Code Division Multiple Access, referred to as: WCDMA), CDMA 2000 system (English: Code Division Multiple Access, referred to as: CDMA2000), TDS-CDMA system (English: Time Division-Synchronization Code Division Multiple Access, referred to as: TD-SCDMA), it drills for a long time Into system (English: Long Term Evolution, abbreviation: LTE), and next generation's 5G mobile communication system.

In communication system shown in Fig. 1, integrated access and backhaul IAB system are given.One IAB system is at least Including a base station 100, usual base station 100 referred to as DgNB (Donor gNB, DgNB) and the one or more that it is serviced UE 101, one or more relay node rTRP 110, the rTRP 110 are connected to base station 100 by wireless backhaul link 113, And one or more UE 111 that the rTRP 110 is serviced.Base station includes but is not limited to: evolved node B (evolved Node Base, eNB), radio network controller (Radio Network Controller, RNC), node B (Node B, NB), Base station controller (Base Station Controller, BSC), base transceiver station (Base Transceiver Station, BTS), Home eNodeB (for example, Home evolved NodeB or Home Node B, HNB), Base Band Unit (BaseBand Unit, BBU) or the next-generation new radio base station (NR, New Radio) (such as gNB) etc..

It is integrated access and back haul system can also include another or multiple relay node rTRP 120, this or Multiple relay node rTRP 120 are connected to relay node rTRP 110 by wireless backhaul link 123 to be linked into system, And its one or more UE 121 serviced.In figure, relay node rTRP 110 and rTRP 120 pass through wireless backhaul chain Road is connected to network.In this application, the wireless backhaul link is returned from the perspective of relay node, such as wirelessly Journey link 113 is the backhaul link of relay node rTRP 110, and wireless backhaul link 123 is the backhaul of relay node rTRP 120 Link.As shown in Figure 1, a relay node, such as 120, can by wireless backhaul link, such as 123, connect another relaying section Point, such as 110, are thus connected to network, moreover, wireless relay system can be by multistage wireless relay connection to network.In general, The node of offer wireless backhaul link resource, such as 110, referred to as upstream node, being linked into network by wireless backhaul link Relay node, such as 120, referred to as downstream node.In general, downstream node can be regarded as a user equipment of upstream node UE.It should be understood that in integration access shown in FIG. 1 and back haul system, relay node one upstream node of connection, but In following relay system, in order to improve the reliability of wireless backhaul link, a relay node, such as 120 can have on multiple Trip node provides service simultaneously for a relay node.In this application, the user equipment (UE) 102,112,122, can be Static or mobile device.Such as mobile device can be mobile phone, intelligent terminal, tablet computer (tablet), notebook electricity Brain (laptop), video game console, multimedia player even move or static relay node etc..Static equipment It is usually located at fixed position, such as computer, access point (is connected to network, such as relay node by Radio Link).Relaying section The title of point rTRP 110,120 is not intended to limit the scene or network that it is disposed, and can be such as relay, RN etc. any other Title.The application is only the needs for facilitating description using rTRP.

In Fig. 1, all Radio Links 102,112,122,113,123 are all two-way links, including uplink and downlink pass Transmission link, particularly, wireless backhaul link 113,123 can be used for upstream node and provide service for downstream node, as upstream is saved Point 100 provides wireless backhaul service for downstream node 110.The downlink transfer refers to upstream node, is downstream such as node 100 Node is transmitted such as node 110, and uplink refers to downstream node, such as node 110, gives upstream node, such as node 100, Transmit data.The node is not limited to network node or UE, for example, in D2D (Device to Device, D2D) scene Under, UE can serve as relay node as other UE service.Wireless backhaul link can be access link again in some scenarios, such as Backhaul link 123 can also be considered access link for node 110, and backhaul link 113 is also the access chain of node 100 Road.The present invention will be mainly illustrated with downlink transfer, it should be noted that all methods also will to the transmission of up direction It is applicable in.

When relay node is under half-duplex constraint, for time division duplex (Time Division Duplexing, TDD) band Interior relaying, wireless backhaul link are overlapped with the frequency spectrum resource of access link, and downlink wireless backhaul link of the rTRP in base station carries out When reception, it cannot be transmitted on the uplink to subordinate UE or equipment；And rTRP is carried out on backhaul link to base station When row transmission, the transmission of subordinate UE or equipment on uplink access link cannot be connect.

Above-mentioned half-duplex constraint under, should be avoided backhaul link and access link equidirectional transmitted and caused by when Domain transmission collision, such as the downlink transfer in the downlink transfer and access link on backhaul link.In LTE, backhaul link is used Semi-static reserved resource is not in the above transmitting-receiving conflict.And in NR, due to accessing the integrated design with backhaul link, The variation of access link may result in the dynamic change of backhaul link, to cause conflicting for backhaul link and access link. It, can be by dispatching to avoid conflict, but for the periodic signal of access link for the resource of the dynamic dispatching of access link Unlike resource, such as TRS and LTE CRS, which is not fixation, can be with flexible configuration, therefore, this Under flexible configuration mechanism, rTRP can be with separate configurations periodic signal, to improve preferable system performance, therefore, so that the period believes Number collision avoidance mechanism relative data transmission dynamic dispatching it is more difficult.

When above-mentioned conflict occurs, rTRP must abandon periodic signal on data receiver or access link on backhaul link Transmission, the reliability of backhaul link can be reduced by abandoning the data receiver on backhaul link, and abandon access link periodic signal Transmission may cause the serious error of UE.The performance of rTRP can both be seriously affected.

In order to enable supporting the relay node rTRP of IAB that there is the flexibility centainly dispatched, while avoided again due to rTRP The transmission of transmission on access link, especially cyclical signal and the scheduling of backhaul link clash, and can permit Receiving upstream node after node rTRP, such as DgNB (Donor gNB, DgNB), backhaul link resource configuration when, according to working as The periodic signal resource of preceding configuration determines the entry-into-force time of backhaul resources configuration, to effectively avoid the configuration due to upstream node Caused by resource contention, meanwhile, can make rTRP have certain freedom degree be not necessarily to when carrying out period resource distribution The resource for notifying its periodic signal configured of upstream node, to save unnecessary signaling overheads.

When relay node rTRP receives upstream node, such as DgNB, when the backhaul link resource of configuration, since upstream node is matched The resource set may have lap with relay node for the UE or equipment of its service resource configured, therefore, it is undesirable that The backhaul link resource configured enables immediately, but the UE or equipment for needing that relay node is waited to service it carry out resource weight After matching, then enable backhaul link resource configuration.So the backhaul link resource that relay node needs that upstream node is notified to be configured Entry-into-force time point, to avoid the backhaul link resource that upstream node is configured is enabled immediately and cause with relay node be its What the UE or equipment serviced was configured, such as periodic signal, it clashes.Entry-into-force time point, which refers to, is receiving upstream node After resource distribution sometime, the so-called moment refers to some subframe or some time slot (slot) or some symbol in subframe Initial position.

After relay node determines the entry-into-force time point of backhaul link resource, a configuration response is sent to upstream node and is disappeared Breath, wherein the entry-into-force time point of the resource configured comprising upstream node.

Since the period of unlike signal and required resource may be different, upstream node may such as base station gNB A resource set is configured for relay node rTRP, the present invention is known as first resource config set, that is, first resource config set is first The resource distribution collection of the network equipment and the second LA Management Room link.First resource config set may include at least one resource Group, the resource of each resource group include one of at least following information: the cycle information of resource, running time-frequency resource information, resource Type information, Configuration Type instruction, the corresponding index of resource group.

When upstream node is that relay node rTRP configures multiple resource groups, at least one resource group therein can be activated As the transfer resource of current backhaul link, and the resource that other are not activated is as standby resources.Multiple resource groups of configuration The resource that all cannot be used for the transmission of periodic signal, but be not activated can be used to be counted for the UE that it is serviced by relay node According to transmission.Moreover, upstream node can be provided according to the needs of channel variation or the variation of backhaul link transmission rate to first Source config set is reconfigured, or reactivates the resource of at least one resource group for backhaul link transmission.

Fig. 2 Signalling exchange flow chart between network element provided by the embodiments of the present application.Wherein first network equipment 200 can be Relay node 110 in Fig. 1, second network equipment 210 can be the base station 110 in Fig. 1；First network equipment can also be figure Relay node 120 in 1, second network equipment can be the relay node 110 in Fig. 1.That is, first network equipment is in Fig. 1 After the downstream node in system, second network equipment is the upstream node in Fig. 1, wherein upstream node, relay node and under Trip node is also possible to UE, for example, using certain UE to provide service as relay node for other UE under certain D2D scenes. The embodiment of the present application has follow steps.

S201, first network equipment 200 receive the first resource config set that second network equipment 210 is sent.

Second network equipment determines first resource config set, and sends first resource config set to first network equipment.Its In, first resource config set includes at least one resource group, and each resource group includes following at least one information: the rope of resource group Fuse breath, the cycle information of the frequency domain information of the time domain assignation information of resource, the type information of resource, resource, resource, configuration class Type indicates information.

The index information of resource group is used to be identified for each resource group in first resource config set, so as to subsequent logical The index information of the resource group is crossed one group of resource in first resource config set is activated or is reconfigured.In general, the second net For network equipment using the resource with same period as a resource group, the resource of different cycles belongs to different resource groups.Pass through The different periods realizes the configuration of different backhaul link resource demands.When only configuring one group of resource, the index information of resource group It is not required.

The time domain assignation information of resource is the time-domain information of one group of resource in first resource config set.In tdd mode, Since backhaul transport and the access link transmission of rTRP cannot appear in same direction simultaneously, i.e., downlink transfer cannot be carried out simultaneously Or uplink, therefore, backhaul link and access link are in time domain mutual exclusion.To FDD, then can by the frequency domain information of resource come Realize the configuration of return link resource.Particularly, the time-frequency assignation information of resource includes the assignment of symbol.Especially in certain configurations In, the configuration of periodic signal is only configured on certain symbols of certain subframes, then other symbols then can be used for moving State scheduling.For example, the such as 12-13 sign bit that base station 100 can assign some subframe is transmitted for periodic signal, and symbol 0-10 leaves the transmission that rTRP carries out data for, and the 11st symbol is converted as uplink and downlink.

The type of resource includes following at least one type: main resource and auxiliary resources, that is, the type information of resource is used One group of resource in configuration first resource config set is main resource or auxiliary resources.In a kind of possible implementation In, second network equipment can configure main resource for rTRP and auxiliary resources, main resource referred within the relatively long time, Resource distribution remains unchanged, and the transmission for backhaul link that is bound to, and auxiliary resources is then the needs according to backhaul link The resource that dynamic uses is to carry out dynamic dispatching by PDCCH, if certain to depend on backhaul link for backhaul link Actual bandwidth needs.To these two types of resources, rTRP not can be carried out periodic signal, such as CSI-RS, the transmission of TRS, SSB.It is right Main resource, rTRP cannot be used, and to auxiliary resources, if backhaul link does not use, be can be used for rTRP and taken by it The UE or equipment of business carry out data transmission.At this point, it is main that second network equipment is specified for the resource group in first resource config set Resource or auxiliary resources are wanted to help rTRP to determine configuration and the data dispatch of periodic signal.

The cycle information of resource includes: the sequence or sequence index used, port numbers, sub-frame configuration, in power at least It is a kind of.

The resource that Configuration Type is used to indicate in first resource config set is used as increment configuration and still reconfigures completely. Configuration Type instruction can be as each resource group separate configurations in first resource config set, also can be applied to the first money All resource groups in the config set of source.Wherein, increment configuration is to increase or decrease part resource on the basis of existing resource Configuration method, that is, only increase or decrease part resource；Reconfigure completely is to replace existing resource with completely new resource distribution Configuration method, that is, the resource of all first resource config sets configured before reconfiguration completely is considered in vain, with what is newly configured The first resource config set of first resource config set substitution former configuration.

S202, first network equipment determine the resource entry-into-force time point of the first resource config set.

First network equipment 200 determines resource entry-into-force time point after receiving the first resource config set of backhaul link, And to network-feedback resource entry-into-force time point.The resource entry-into-force time point includes at least one of following information: system-frame Number SFN (System Frame Number), subframe numbers or deviant, the resource group of the backhaul link of configuration, in time of day At least one of.For example, can indicate some resource group entry-into-force time point or received first by SFN and subframe numbers No. SFN of resource distribution collection and a deviant, wherein deviant is one of following combination: radio frames and subframe, wirelessly Frame and time slot or radio frames and symbol or radio frames and subframe and symbol or radio frames and time slot and symbol；Deviant can also To be using subframe or time slot or symbol as the count value of unit, deviant even further includes the relevant information of subframe, the son The relevant information of frame includes subcarrier spacing used in subframe, TTI length etc..Time of day can use subframe or time slot or symbol Number it is used as unit, it can also be by the time of day of protocol definition, such as using some TTI as basic time of day.

After first network equipment receives the first resource config set of the second network equipments configuration, it is thus necessary to determine that resource comes into force Mainly there is periodic signal at time point due to relay node rTRP for the UE or device configuration of its service, such as SS block, CSI- The associated random access resource such as RS, TRS or SS block, or the UE or equipment that are serviced for it carry out data biography It is defeated, since the transmission needs of these signals or data are eating dishes without rice or wine to continue for some time, in order to guarantee these signals or data transmission Performance, rTRP cannot be immediately finished these transmission.When DgNB or some upstream relay node are relay node rTRP configuration When first resource config set and relay node rTRP overlap for the resource of its UE serviced or device configuration, it is possible to It can clash.Therefore, rTRP is after receiving first resource config set, it is thus necessary to determine that the received first resource config set of institute is No and rTRP is currently that its UE for being serviced or device configuration or the resource of scheduling clash.Consider half-duplex constraint, rTRP If periodic signal that UE or equipment that the first resource config set received is serviced in time domain and the rTRP for it are configured or It is just at least partially overlapped in the resource of scheduled transmission, then there is conflict.It is its UE serviced or the dynamic of equipment to rTRP For scheduling, it is typically due to hybrid automatic repeat-request HARQ (Hybrid Automatic Repeat reQuest, English letter Claim HARQ) it retransmits or the interval of uplink UL grant received between data transmission, these resources cannot be used immediately to The transmission of backhaul link.Therefore, rTRP will match according to the first resource config set received and for currently serviced UE or equipment The resource set or dispatched determines that resource entry-into-force time point, i.e. upstream node will be used for when coming into force of the resource of backhaul link It carves.Before the resource comes into force the moment, UE or device configuration period letter that rTRP can be serviced by scheduling or again for it Number to avoid and by the conflict of backhaul resources to be used.

S203, first network equipment feed back the resource entry-into-force time point of first resource config set to second network equipment.

It, will be to second network equipment after rTRP determines resource entry-into-force time point, that is, (such as DgNB is it to upstream node The upstream rTRP of service) resource entry-into-force time point is sent to respond the first resource config set of second network equipment transmission.Second The network equipment activates one group in first resource config set after the resource entry-into-force time point for receiving the transmission of first network equipment Or multiple sets of resources.The information that resource entry-into-force time point includes is as described above, repeat no more.

It, can be to avoid between the access link resource and backhaul link resource of first network equipment by the embodiment of the present application Because of resource contention caused by the configuration of cyclical signal, access link transmission performance is promoted.

In a kind of optinal plan, if first network equipment determines between first resource config set and access link resource Do not conflict, first network equipment can only send confirmation message.At this point, second network equipment is receiving the first network hair After the response to first resource config set sent, then it is assumed that the backhaul link resource configured is received and swashed by first network equipment Configured resource living, the resource activated can be any group or multiple sets of resources in the resource group of configuration.

It by the embodiment of the present application, can quickly carry out accordingly, and simplify response message, improve efficiency of transmission.

Fig. 3 is the method flow of determining entry-into-force time point provided by the embodiments of the present application.Fig. 3 embodiment is using TDD as example Son, it should be appreciated that TDD is an example, can also be frequency division duplex (Frequency Division Duplexing, FDD), The various equivalent modifications for any other determination resource entry-into-force time point that those skilled in the art are readily apparent that Or replacement, all should belong to the invention discloses technical scope.

S300, rTRP first determine whether first resource config set is be overlapped with access link resource.If be not overlapped, really Determine the resource entry-into-force time, otherwise enters in next step.Overlapping include at least configured first resource config set in the time domain and The access link resource of rTRP configuration or scheduling has the identical subframe in part, time slot or symbol.If be not overlapped, determining resource Entry-into-force time can be some time point, be also possible to the instruction information to come into force.

S301, the configuration of access link periodic signal is determined whether there is.If so, then entering step 302, otherwise enter step Rapid 305 to judge whether there is dynamic data dispatch.

S302, determine whether periodic signal closes to an end, described close to an end referred to since current time, at several milliseconds To between several hundred milliseconds, dependent on realization or configuration, but the present embodiment is without limitation on concrete implementation.If the period letter of configuration Number close to an end transmission, then enters step 303.

S303, periodic signal end time point is determined.End time point refers to some time point after current time, It is often referred to some subframe or time slot or symbol of some radio frames.

S304, determine that the deadline is reconfigured in periodic signal.When step 303 judges that periodic signal will not close to an end, RTRP can reconfigure the current UE that it is serviced or the periodic signal that equipment is transmitted, so that the period reconfigured Signal will not be at least overlapped with the first resource config set received in the time domain, when reconfiguring the completion of all periodic signals Between put the earliest entry-into-force time point of namely first resource config set, rTRP is using the time point as resource entry-into-force time point.

S305, dynamic dispatching is determined whether.After the end time for having determined periodic signal, or in step 301 really Being scheduled on access link does not have periodic signal configuration, then rTRP needs it is judged whether or not the UE that is serviced it or equipment Otherwise dynamic dispatching enters S307 if so, then entering S306.

S306, the end time for determining current transmission.That is, determining the time that the dynamic dispatching on access link terminates Point.During being reconfigured to periodic signal or receiving upstream node, such as DgNB or relay node, first resource match Before setting collection, since certain UE or equipment are also in data transmission state, it is therefore desirable to be clicked through to the end time of dynamic dispatching Row judgement.The re-transmission that dynamic dispatching is typically due to eat dishes without rice or wine causes a data transmission that can continue several milliseconds to a few tens of milliseconds, and The transmission of the data of the UE that rTRP services it or equipment is controlled by rTRP, and therefore, rTRP can determine dynamic dispatching The time point of end.

S307, resource entry-into-force time point is determined.When step 300 determines that first resource config set and access link resource exist When overlapping, selection cycle signal terminates time point, periodic signal be reconfigured in deadline point and dynamic dispatching end time point compared with Long one is used as resource entry-into-force time point.When step 300 determines that first resource config set and access link resource be not be overlapped When, then rTRP can determine some time point as resource entry-into-force time point, for example, estimation upstream node is properly received resource life Some time point of time message is imitated as the entry-into-force time, the present embodiment does not constrain or rTRP thinks that first resource configures Collection comes into force, and upstream nodes send the instruction information to come into force, when use the money of first resource config set Source depends on upstream node, and rTRP reserves the resource of first resource config set then to avoid conflict, and how is specific upstream node When use first resource config set, the present embodiment do not constrain.

It should be understood that Fig. 3 is a possible method for judging resource entry-into-force time point, specific implementation and examine Constraint the present embodiment of worry does not limit, any other determination resource that those skilled in the art are readily apparent that The various equivalent modifications or substitutions of entry-into-force time point, all should belong to the invention discloses technical scope.For example, in Fig. 3 It may first determine the end time of the dynamic dispatching in step 305, then judge periodic signal.Here a possible reality is only provided Applying method.

By the embodiment of the present application, resource entry-into-force time point can be determined, avoid the periodic signal or dynamic on access link The resource of state scheduling and the backhaul link resource conflict of upstream node configuration, promote the transmission performance of access link.

In a kind of optional scheme, first network equipment, can also be to second before receiving first resource config set The information that the network equipment reports the resource for being not useable for backhaul link or can be used for backhaul link resource, Fig. 4 are the application implementation The method flow for the resource report that example provides.

S401, first network equipment 200 send the report of Secondary resource config set to second network equipment 210.

First network equipment 200 can send Secondary resource to second network equipment and match before first resource config set Collection report is set, Secondary resource config set is the resource distribution collection of the downstream node of first network equipment 200.Second network equipment 210 receive Secondary resource config set report after, according to Secondary resource config set be assured which resource can with or not It can be used for backhaul link transmission.Secondary resource config set specifically includes the resource that access link cyclical signal uses, or The resource not used by access link, it includes information it is similar with aforementioned first resource config set, repeat no more.First The network equipment 200 sends the report of Secondary resource config set to second network equipment 210, and Secondary resource config set therein is mainly used First resource config set is determined in second network equipment 210, avoids the resource and Secondary resource config set of first resource config set Resource overlapping at least in the time domain, or reduce the resource of overlapping.

In a kind of possible realization, rTRP can also report whether support LTE user, if supporting LTE user, The configuration information of LTE user and MBSFN sub-frame is supported in instruction in the report of Secondary resource config set.

S402, second network equipment 210 send the report response of Secondary resource config set to first network equipment 200.

The report response of Secondary resource config set can be to Secondary resource config set in the report of Secondary resource config set really Recognize, indicates the conflicting resource of resource that backhaul link transmission not will use and give in Secondary resource config set, Secondary resource Config set reports that response message is optional.In a kind of optinal plan, second network equipment 210 is according to second network equipment 210 The report of Secondary resource config set is sent, first resource config set is determined, and reconfigure backhaul link resource, that is, uses first resource Config set message replaces Secondary resource config set to report response message, indicates that second network equipment 210 may partially receive resource Resource distribution in Secondary resource config set, or do not receive the resource distribution in Secondary resource config set.At this point, the first net Network equipment 200 needs the backhaul resources avoided with specified in first resource config set to conflict.That is, second network equipment 210 after receiving the Secondary resource config set of first network equipment 200, can directly transmit a Secondary resource config set and ring It answers, or sends first resource config set message, concrete implementation mode this embodiment does not constrain.

Step S403-S405 is repeated no more with the S201-S203 of Fig. 2.

By the embodiment of the present application, can make second network equipment is the backhaul link resource of first network device configuration Conflict minimize, improve the efficiency of resource distribution, promote the transmission performance of access link.

In a kind of optional scheme, second network equipment 210 can also report with activly request first network equipment 200 The report of two resource distribution collection.Fig. 5 is the method flow of resource request provided by the embodiments of the present application.

S501, first network equipment connect the Secondary resource config set request of 200 second network equipments of reception 210 transmission.

Second network equipment 210 determines the need for configuring first resource config set, Huo Zhegen for first network equipment 210 It determines the need for increasing according to the Buffer Status Report BSR (Buffer Status Report, BSR) of first network equipment 200 Add backhaul link resource, if it is determined that need to configure first resource config set or increase backhaul link resource, then to first network Equipment 200 sends the request of Secondary resource config set.The request of Secondary resource config set can be sent by physical layer signaling, such as A bit is carried in physical downlink control channel PDCCH (Physical Downlink Control Channel, PDCCH) Instruction information, or using certain format PDCCH, specifically can be by protocol definition；Or pass through MAC (Medium Access Control, MAC) layer control signaling MAC CE (MAC Control Element, MAC CE)；Or by wireless Resources control RRC (Radio Resource Control, RRC) message is requested to send.

First network equipment 200 receives resource using the step of after request message, step is with Fig. 4, repeats no more.

By the embodiment of the present application so that the first resource config set of the second network equipments configuration is more accurate, reduce by The possible multiple information exchange caused by resource contention causes to configure the longer problem of time delay.Pass through activly request first The network equipment 200 carries out the transmission of Secondary resource config set report, promotes Allocation Efficiency.

In a kind of optional scheme, second network equipment 210, can be to first after completing first resource config set Resource distribution collection is reconfigured.Fig. 6 is the method for reconfiguration process of first resource config set provided by the embodiments of the present application.

S601, first network equipment 200 receive the reconfiguration message that second network equipment 210 is sent, and described reconfigure disappears Breath is for reconfiguring first resource config set.Second network equipment 210 can be according to backhaul link, such as bandwidth, letter Road variation etc., adjusts backhaul link resource, redefines first resource config set, and be allocated to first network equipment 200.This is heavy Configure message can aforementioned first network equipment 200 complete first resource config set after whenever progress.It reconfigures Message is mainly used for being adjusted backhaul link resource or be reconfigured completely to optimize transmission performance.In some cases, Since the handling capacity that the variation of access link number of users or link will lead to access link changes, correspondingly, backhaul link Resource will be also adjusted to adapt to access link bandwidth.

Reconfiguring for first resource config set can be reconfiguration completely or increment reconfiguration, is reconfigured completely, refers to complete reconfiguration The resource of all first resource config sets configured before, the money of all first resource config sets is considered after complete reconfiguration In vain, the first resource config set of former configuration is replaced with the first resource config set newly configured.Then only part provides for increment reconfiguration Source reconfiguration can pass through the resource of first resource config set if first resource config set includes the index information of resource group The index information of group reconfigures the resource of first resource config set.

In a kind of optional scheme, can be distinguished by a type of message instruction is the reconfiguration of first resource config set The message of the message or first resource config set set.Type of message instruction indicates that current message is first resource config set The message that message or first resource config set reconfigure.If it is first resource config set reconfiguration message, then should also distinguish It is complete reconfiguration and increment reconfiguration.

S602-S603 is repeated no more with the S202-S203 in Fig. 2.

By the embodiment of the present application, reconfiguring so that resource utilization is improved to backhaul resources may be implemented, and And access link and backhaul link bandwidth adaptation are adapted to, lifting system performance.

In a kind of optinal plan, above-mentioned first resource config set can also further include another second network equipment Resource distribution.In some scenarios, a link may cause terminal or rate not to be able to satisfy rTRP's due to many reasons The requirement of backhaul link can enable two backhaul links simultaneously then as same rTRP service.Two the second networks are set at this time Standby be the upstream node of rTRP simultaneously, and is serviced for the same rTRP.The embodiment of the present application claims in two second network equipments Second network equipment based on one, second network equipment supplemented by another, wherein main second network equipment provides control for user Function, auxiliary second network equipment then mainly provide data-transformation facility.In such a scenario, generally for avoiding main second network The resource distribution of equipment and auxiliary second network equipment clashes, need main second network equipment and auxiliary second network equipment it Between coordinated, to avoid the configuration conflict of two second network equipments, and main second network equipment and auxiliary second network are set It can directly hold consultation between standby, and unified configuration is carried out by main second network equipment, second network equipment of master and auxiliary the Two network equipments can also respectively configure its resource, but the resource configured is the resource after negotiating.Concrete mode Dependent on protocol definition.Fig. 7 is the process that two the second LA Management Rooms provided by the embodiments of the present application are held consultation.Step is such as Under:

S701, main second network equipment send resource negotiation request to auxiliary second network equipment to request auxiliary second network to set The standby rTRP for request configures first resource config set.Indicate it is the first of which relay node rTRP in resource negotiation request Resource distribution collection.The first resource config set of multiple rTRP can be requested simultaneously.In the request, it also may include main second network Equipment is the first resource config set of the rTRP configuration of request.

S702, auxiliary second network equipment are after receiving resource negotiation request, and feedback resources negotiate response, wherein being included as one The first resource config set that a or multiple rTRP are respectively configured.

If the resource and main second network equipment in the response of S703, resource negotiation be the resource of same rTRP configuration not Conflict then sends simple resource negotiation confirmation to auxiliary second network equipment.Otherwise a resource distribution collection not conflicted is sent, The resource distribution collection not conflicted is for the backhaul link transmission between auxiliary second network equipment and rTRP.

Above-mentioned resource negotiation request message and resource negotiation response message can be transmitted by RRC agreement.

It should be understood that message above name is only used for indicating function, actual message name may be different from this, but main function Can negotiate backhaul resources for rTRP.Any other message name replacement with the same or similar functions changes, all at this The protection scope of invention.

Pass through the embodiment of the present application, it is ensured that the backhaul link resource of the first network equipment with multiple upstream nodes It will not clash, reduce transmission interference, and reduce and eat dishes without rice or wine due to repeatedly negotiating bring caused by avoiding resource from being overlapped Signaling overheads.

In a kind of optional scheme, rTRP can also lead in Secondary resource config set report message shown in Figure 4 and 5 Know upstream node (such as base station 100), the first resource config set that other upstream nodes configure for it.Since the same rTRP can be with Support two or more upstream nodes, therefore, each upstream node be the rTRP configuration resource there can be no conflicts.One kind can Capable implementation method is other upstream nodes of upstream node can be notified for the of its configuration in the report of Secondary resource config set One resource distribution collection, this is provided between being very beneficial for solving multiple upstream nodes when being unable to direct communication multiple upstream nodes The problem of source configuration conflict.

In a kind of optional scheme, after the first network equipment feedback resources entry-into-force time, may further comprise: Two network equipments are activated and/or are deactivated one or more groups of resources in first resource config set by signaling.When the second network Equipment be first network device configuration first resource config set in include multiple resource groups when, especially include main resource and When auxiliary resources, first resource can be activated or deactivated by physical layer descending control signaling PDCCH or MAC CE or RRC One or more groups of resources in config set.It should be understood that first network equipment cannot on main resource when configuring multiple sets of resources Configure periodic signal.Therefore, when the main resource of configuration is not activated, first network equipment, which can be used, not to be activated Main resource is transmitted for data.Once being activated, then it cannot be used for data transmission.When activating the first money using above-mentioned signaling One or more groups of resources in the config set of source should provide the index information of resource group in signaling.

The flexible change of resource can be realized to fit by simply activating and/or deactivating signaling through this embodiment The fast-changing scene of backhaul link bandwidth is answered, configuration or the first resource config set of frequent first resource config set are avoided Reconfigure bring signaling overheads.

In a kind of optional scheme, activates in signaling and the instruction of resource group is carried out using Bit String.Fig. 8 is the application implementation The activation configuration method for the resource group that example provides.When the resource group of configuration is more, when assigning multiple resource groups simultaneously, often A resource group all indexs of reference will consume more signaling overheads to carry out instruction.A kind of possible mode is by different money Source changes a corresponding bit, and the corresponding bit of all resource groups is put together to form a Bit String (bitmap).Fig. 8 In, the Bit String that Bitmap800 is formed by the corresponding bit 801-805 of 5 resource groups, first group and second group resource of expression will It is assigned to the resource of backhaul link transmission.

The mode of Bit String through this embodiment can reduce signaling overheads, improve allocative efficiency.

In a kind of optional scheme, first network equipment receives the conversion that second network equipment is sent and indicates information.? When with multilevel relay, if first network equipment and second network equipment are all relay node, and second network equipment For the upstream node of first network equipment, second network equipment is first network device configuration first resource config set at this time.It can Routing can be caused to change, it is likely that second network equipment becomes under first network equipment due to the variation of network environment Node is swum, in this case, to guarantee that transmission is not disrupted, first network equipment receives the conversion that second network equipment is sent It indicates information, indicates that second network equipment will carry out backhaul link transmission by first network equipment.It should be understood that in conversion Before downstream node, second network equipment receives the control of its superior node, therefore, remains as control node, so needing logical The control for crossing second network equipment to be converted.The conversion instruction information can be carried on RRC or MAC CE or PDCCH In message.

After first network equipment receives conversion instruction information, backhaul link resource association will be carried out with second network equipment It adjusts, method such as earlier figures 2, Fig. 4, method shown in fig. 5 repeats no more.Optionally, second network equipment is to first network While equipment sends conversion instruction information, first can also will be given for the resource report of its terminal or downstream node that are serviced The network equipment, that is, have the function of the report of Secondary resource config set, as previously mentioned, repeating no more.

Through this embodiment, in the network for avoiding multistage wireless from relaying, in the case where there is transformation due to upstream and downstream node, Need route finding process again and bring data-transmission interruptions and the too long problem of time delay.Therefore, it effectively reduces The delay of transformation bring and data-transmission interruptions due to node.

In a kind of optional scheme, the first resource config set and/or first resource config set of aforementioned all embodiments Reconfiguration message can be carried on the PDSCH (Physical of RRC signaling or MAC CE signaling or PDCCH or PDCCH assignment Downlink Sharing Channel, PDSCH) in resource.In comparison, backhaul link resource is carried out using PDCCH to refer to With quick resource reconfiguration is able to achieve, still, when carrying out the configuration of first resource config set using physical layer signaling, it is suitble to configuration First resource config set the smaller scene of stock number.When being configured in the PDSCH resource using PDCCH assignment, Comprising instruction information in PDCCH assignment message, instruction information is for indicating that distributed PDSCH is to be used for transmission first resource to match Collection is set, physical layer completes the resource distribution of first resource config set at this time.

Through this embodiment, providing a variety of flexible configuration signals makes the message transmission of foregoing embodiments be able to reality It is existing, and it is adapted to a variety of different application scenarios.

Fig. 9 is the representation method of multiple sets of resources provided by the embodiments of the present application.First resource configuration in previous embodiment Collection and Secondary resource config set can be there are two types of representation methods: being not useable for the resource of backhaul link, or can be used for backhaul chain The resource on road.The embodiment of the present application is to be not useable for the resource of backhaul link as scheme explanation, it should be appreciated that reporting can be used for back The resource of journey link has the same or similar method, also within protection scope of the present invention.

By taking the downlink transfer of backhaul link as an example, the resource for being not useable for backhaul link includes: first network equipment 200 exists The periodic signal sent on access link, such as synchronous associated random access resource of block SS block, TRS, SS block Deng and first network equipment 200 to the monitoring windows of other network node signals, such as the beam scanning of SSB or CSI-RS.For The signaling overheads for reducing the report of Secondary resource config set needs a kind of effective method to report the access of first network equipment The use state of link circuit resource.

First network equipment, such as rTRP, the period reported send a signal to the synchronization signal block SS sent less comprising itself Block, at least partly CSI-RS, TRS, the associated random access resource of SS block, and need received from other sections The above-mentioned periodic reference signal of point.A kind of method that Fig. 9 uses virtual period signal reporting, the virtual period signal indicate The time interval for multiple periodic signals that first network equipment reports is not necessarily identical as the periodic signal of wherein some resource. It may include multiple and different periodic signals in one virtual period.For example, as in a virtual period 900, contained in figure The resource distribution of 912,913,914 three different periodic signals, these signals is different, and passes for different periodic signals Defeated, different periodic signals have different priority.Different signal types and/or priority are conducive to second network equipment Which determine resource and should retain to clash to avoid the access link resource with first network equipment.For example, grade one is Synchronization signal block SS block, grade two are TRS and period CSI-RS etc..Alternatively, rTRP be report unavailable resource (or week Phase signal) clear configuration level, agreement does not provide the grade of each periodic signal, but may provide shared by high-grade signal reporting The maximum ratio of resource.All occurring in radio frames 910 and 920 such as 912 and 914, the period is 10 subframe lengths, 911, 921,931 indicate the subframe for being not used in periodic signal transmission, and 913 period is then 20 subframe lengths.912 in figure, 922,9932 frequency domain resource configurations having the same, they are located at the different location of different subframe expressions in the time domain, equally , 914,924,934 frequency domain resource configurations having the same, 913,933 frequency domain resource configurations having the same.Report when It waits, including at least the configuration information of subframe or time slot or symbol of each periodic signal in a virtual period, virtual period Starter system frame number SFN and/or subframe numbers, cycle length, frequency domain resource information (such as starting material of each periodic signal resource Manage the frequency-domain physical resource number of resource location and occupancy), time-domain position of each periodic signal in virtual period, every kind of period letter Number type and priority in one or more information.In the scheduling granularity that more refines of future, time-domain resource can be with One subframe or several subframes or time slot are unit, and it is single for being also possible to one or more symbols in a subframe or time slot Position is configured.

It should be understood that being only an example shown in Fig. 9, specific virtual period length, wireless frame length, son are not constrained Frame length, the subframe numbers or symbolic number of the resource of configuration.Include since different Numerology will lead in a radio frames Subframe or number of timeslots it is different, the symbolic number for including in a subframe is different.Specific frame structure caused by these factors is not With the basic skills for having no effect on the program, all within protection scope of the present invention.

Through this embodiment, effectively multiple groups periodic signal can be indicated, to reduce signaling overheads, and passes through differentiation The use of different resource avoids the change to important periodic signal as far as possible, thus lifting system performance.

In a kind of optinal plan, first network equipment can also only report unavailable resource, not distinguish different resource class Type and/or priority.Therefore, subframe or time slot when reporting, comprising each periodic signal in a virtual period Or the configuration information of symbol, the starter system frame number SFN and/or frame number of virtual period, cycle length, each unavailable resource exist The time-domain position and/or frequency domain resource of virtual period configure.Without the type comprising each periodic signal and/or priority etc., To reduce the signaling overheads of resource reporting.

In a kind of optinal plan, first network equipment can report the configuration of partial periodicity signal and its corresponding type And/or priority, and periodical differentiation is not done to other resources, sending cycle signal can be reported simultaneously and reports unavailable money Source.For example, synchronous information block burst collection (Synchronization Signal block burst set, SS block Burst set) its configuration can be directly reported, and CSI-RS and TRS etc. can pass through virtual period signal method or unavailable resource Method is reported.The method reported by multiple resources can provide the flexibility of resource distribution, reduce signaling overheads.

In a kind of optinal plan, first network equipment can indicate reported money in the report of Secondary resource config set Source is that complete update reports or incremental update reports, and is reported if it is complete update, second network equipment is receiving the first net Configuration information before should being abandoned after the Secondary resource config set report that network equipment is sent, using new configuration as backhaul link The configuration of resource refers to.If it is incremental update, then first network equipment should be noted that the resource information of increase and/or deletion. In such a way that the embodiment of the present application can provide a variety of Secondary resource config set reports, flexibly and easily, maximizing reduces signaling Expense.

In a kind of optinal plan, second network equipment only configures the resource that backhaul link is used in some cycles.Figure 10 For a kind of configuration method of aperiodic resource provided by the embodiments of the present application.In Figure 10, in the time that the period is N number of subframe Interior, subframe 2,3,4 is configurable for backhaul link resource, is not grouped to resource.When being configured to resource, Instruction is complete reconfiguration or increment configuration in configuration message, and if it is complete configuration, then new received resource distribution is in resource Original resource distribution will be completely covered after coming into force.It is configured if it is increment, then indicates which resource is to increase in configuration message The resource of the resource or deletion that add, method is as previously mentioned, repeat no more.

By the embodiment of the present application, the service life of resource is specified, it can be to avoid to the fast-changing backhaul link of bandwidth The long-term configuration bring wasting of resources, improves the service efficiency of frequency spectrum resource.

In a kind of optinal plan, a PDCCH can assign multiple groups backhaul link resource simultaneously.In previous embodiment, When carrying out the assignment of backhaul link using PDCCH, multiple groups backhaul link money can be assigned simultaneously in a PDCCH signaling Source.Figure 11 is the method that PDCCH provided by the embodiments of the present application assigns multiple sets of resources.One PDCCH can control multiple groups backhaul The distribution of link circuit resource.As PDCCH 1100 controls first group of resource 1101, second group of resource 1102, third group resource 1103. This method with a PDCCH control multiple sets of resources, suitable for the aforementioned configuration side for carrying out first resource config set with PDCCH Method, or first resource config set is assigned with PDCCH, such as resource distribution is carried out with bitmap.

The present embodiment completes the configuration of multiple sets of resources by a PDCCH signaling, improves the allocative efficiency of backhaul link, drops Low signaling overheads.

In a kind of optinal plan, a PDCCH configures one group of backhaul link resource, completes multiple groups by multiple PDCCH The configuration of resource.Figure 12 is the method that PDCCH provided by the embodiments of the present application assigns one group of resource.Each PDCCH configures one group Backhaul link resource, if PDCCH 1200 configures first group of backhaul link resource 1201, PDCCH 1202 configures second group of backhaul Link circuit resource 1203, PDCCH 1204 configure third group backhaul link resource 1205.If aforementioned carry out the first money using PDCCH When the configuration of source config set, if to configure multiple sets of resources, need to carry out resource distribution using multiple PDCCH.PDCCH can be with Full resource configuration or incremental resource configuration are carried out, method is the same, repeats no more.
