Under a kind of application scenarios, in network each neighbor cell base station (i.e. adjacent base station) between by the service condition of the PRB of mutual (one or more) neighbor cell of direct interface between base station or indirect interface so that the service condition of the PRB of neighbor cell is known in each base station according to interactive information.

In actual applications, can periodically (concrete interaction cycle specifically can set according to concrete scene) between adjacent base station, or under the triggering of one or more trigger events, the utilization power of the PRB of mutual neighbor cell.For example, trigger event C1 can be: the amplitude of variation of the utilization rate of the up PRB (and/or descending PRB) of community exceedes the threshold value of setting (such as can be 20%, 40% or other value); Trigger event C2 can be: the amplitude of variation of the ratio of the utilization rate of up PRB and the utilization rate of descending PRB exceedes the threshold value of setting (be such as 10%, 20% or other value).

Such as, certain community that macro base station M1 is administrative (is expressed as community C _m1, community C _m1for macrocell) (be expressed as community C with administrative certain community of Pico base station P1 _p1, community C _p1for Pico community) neighbor cell each other, administrative certain community of macro base station M2 (is expressed as community C _m2) with the administrative community C of Pico base station P1 _p1neighbor cell each other; Macro base station M1 and Pico base station P1 can be periodic, or under the triggering of trigger event C1 and/or trigger event C2, the service condition of mutual respective cell uplink/downlink PRB, macro base station M1 can know the community C under the P1 of Pico base station accordingly _p1uplink/downlink PRB whether not enough.

Similar, macro base station M2 and Pico base station P1 also can be periodic, or under the triggering of trigger event C1 and/or trigger event C2, the service condition of mutual respective cell uplink/downlink PRB.

Macro base station M1 and Pico base station P1 can at mutual load related messages, indicate the service condition instruction of carrying PRB in the message of radio resource state or other message, the instruction of this service condition can indicate the utilization rate of cell uplink in the unit interval/descending PRB, or indicate the use number of cell uplink in the unit interval/descending PRB, or indicate the uplink/downlink PRB whether this community exists redundancy, or whether the uplink/downlink PRB indicating this community is not enough, or for indicating the information that other can characterize the service condition of uplink/downlink PRB, the service condition of the PRB of neighbor cell is known in base station according to interactive information.

The deficiency of cell downlink PRB can embody by the high utilization rate of descending PRB, also can reflect by the one or more of following information: community Access class barring, community user service quality is not high or community user satisfaction is low.

In actual applications, for reducing the signaling consumption of the service condition of mutual community PRB between base station, such as average for correspondence 10 (or other number) PRB can be used as a grade, when using the amplitude of variation of PRB to reach 10 (or other number) PRB, base station is just carried out alternately.Between base station, the service condition of the mutual community PRB mode that also available index indicates is carried out, and can well reduce signaling consumption mutual between base station like this.Table 1 citing shows the corresponding relation that a kind of index and PRB use number:

Table 1

Index	DL/UL	Average use PRB number
			0000	DL or UL	10
0001	DL or UL	20
			0010	DL or UL	30
0011	DL or UL	40
			0100	DL or UL	50
0101	DL or UL	60
			0110	DL or UL	70
0111	DL or UL	80
			1000	DL or UL	90
1001	DL or UL	100

For the corresponding relation shown in table 1, such as index 0000 indicates average use 10 PRB, and index 1000 indicates average use 90 PRB, and the rest may be inferred.

203, macro base station M1 adjusts community C _m1the configuration of PRB, with by macrocell C _m1the PRB of part or all of redundancy is supplied to the access link that Pico base station is used as community;

Under a kind of application scenarios, whether macro base station M1 judgement reduces community C _m1the configuration quantity of descending PRB, can carry out with reference to one or more in following three reference conditions:

Reference conditions one: the community C of macro base station M1 _m1up PRB have redundancy;

Reference conditions two: Pico base station P1 Xia Yu community C _m1adjacent community (comprises community C _p1) descending PRB not enough;

Reference conditions three: there is stronger cell interference issues between the adjacent base stations such as macro base station M1 and Pico base station P1, now Pico base station P1 may at community C _p1apply RE technology.(due to community C _m1in have (community C comprised to neighbor cell _p1) cell reselection bias configuration and measure the bias configuration that reports, macro base station M1 can be known and community C accordingly _m1adjacent adjacent area C _p1whether apply RE configuration).

Wherein, above-mentioned reference conditions one are essential reference conditions, and reference conditions two and reference conditions three are optional reference conditions.

Macro base station M1 can utilize step 201 and step 202 to know community C _m1with community C _p1the service condition of PRB.Macro base station M1 according to reference conditions one or according to reference conditions one and reference conditions two or according to reference conditions one and reference conditions three or according to reference conditions one and reference conditions two and reference conditions three, can adjudicate and whether adjust community C _m1the configuration of PRB.When reference conditions meet, macro base station M1 can determine to reduce community C _m1the configuration quantity of up PRB, with by community C _m1the PRB of part or all of redundancy is supplied to the access link that Pico base station is used as community.

For ease of understanding, below with macrocell C _m1with Pico community C _p1be FDD community, the cell spectrum resource deployment situation example under network initial state can as shown in Fig. 4-a or Fig. 4-b.

Under network initial state shown in Fig. 4-a and Fig. 4-b, macrocell C _m1with Pico community C _p1up-downgoing frequency range be deployed as can be identical, up-downgoing frequency range is all 20M bandwidth, namely Pico community has the spectrum disposition of empty frame part.Also can be different, without the spectrum disposition of empty frame part on such as Pico community.

Macro base station M1 can according to macrocell C _m1the redundancy condition of ascending resource, by macrocell C _m1the position of PRB carry out (comprising quantity) adjustment of various ways, reduce macrocell C _m1the configuration quantity of up PRB, by macrocell C _m1the part or all of up PRB of redundancy is supplied to Pico base station P1 and is applied to its community access link, and Pico base station P1 then can according to macro base station M1 to macrocell C _m1the position adjustment of PRB, correspondence is newly disposed (or multiple) TDD and is configured the community that compatibility mode or non-TDD configure non-compatible pattern and (can claim community C _p2), be appreciated that the newly deployed community C of Pico base station P1 _p2with macrocell C _m1neighbor cell each other.

Illustrate the various changes of network design state below for heterogeneous network, the situation of homogeneous network and heterogeneous network are similar.

Adjustment scene (one):

Macro base station M1 can reduce macrocell C _m1the quantity of subframe corresponding to whole FDD uplink bands, so that redundancy section subframe is supplied to neighbor cell C _p2configure as descending time slot.Such as network cell deployable state is scene shown in from scene changes shown in Fig. 4-a to Fig. 4-c or Fig. 4-d.

Under such as scene shown in Fig. 4-c, macro base station M1 adjusts macrocell C _m1the position of FDD sub-frame of uplink, make Pico base station P1 newly can dispose the community C of tdd mode _p2.Wherein, the 0th, 1 and 5,6 work song frames in its sub-frame of uplink empty are put, so that Pico base station P1 is configured as neighbor cell C with macro base station M1 in Fig. 4-c _p2descending sub frame be example, can also be other TDD cell configuration mode certainly, configuration mode be similar, does not repeat one by one herein.As shown in table 2, the uplink and downlink timeslot proportion relation of the tdd mode of current definition comprises following 7 kinds, and the configuration mode that same frequency range meets following 7 kinds of uplink and downlink timeslot proportion relations is all the configuration of TDD compatibility.

Table 2

In table 2, D represents sub-frame of uplink, and U represents descending sub frame, and S represents conversion subframe, and conversion subframe can regard a kind of descending sub frame as, the TDD configuration 0 in the corresponding table 2 of Fig. 4-c.

Meanwhile, in order to avoid macrocell C _m1upstream data sends the neighbor cell C on same frequency _p2downlink data receive interference, macrocell C _m1with community C _p2fDD ascending time slot position corresponding to downlink transfer time slot do not send business datum, can send control signaling at the corresponding ascending control channel of this time slot.

Wherein, in scene shown in Fig. 4-a and Fig. 4-c, can community only on FDD UL frequency spectrum on Pico base station, also can outside Shi Chugai community, there is FDD community in addition, the shared identical resource of the position of the sub-frame of uplink of this FDD community and the sub-frame of uplink of this new deployment community.

For when transforming to the application scenarios of such as Fig. 4-c from Fig. 4-a, the proportioning change of TDD ascending-descending subframes (time slot) different on macrocell and/or Pico community can be as shown in table 3.

Table 3

Under such as scene shown in Fig. 4-d, macro base station M1 adjusts macrocell C _m1the position of FDD sub-frame of uplink, Pico base station P1 can newly be disposed community C that non-TDD configures compatibility mode (flexible configuration pattern) _p2.Wherein, front four subframes in its sub-frame of uplink empty are put, so that Pico base station P1 is configured as neighbor cell C with macro base station M1 in Fig. 4-d _p2descending sub frame be example, can also be the compatible cell configuration mode of other non-TDD certainly, configuration mode be similar, does not repeat one by one herein.

In actual applications, base station sends a signal to subscriber equipment at descending time slot, and this downstream signal can experience certain channel, thus when causing arriving user, has certain transmission delay.And subscriber equipment can send signal at ascending time slot, similarly, this signal also can experience certain transmission delay and arrive base station, and base station end arrives the consistent of base station to keep the up moment of all users, thus the time that subscriber equipment needs transmission in advance to postpone sends upward signal to base station.Can think under ordinary meaning, the transmission delay of up-downgoing is identical, and maximum delay spread is relevant with radius of society R.For a TDD user, certain State Transferring from Received signal strength is also needed to become to send the change-over time of the state of signal.

In the TDD configuration mode such as shown in Fig. 4-c; the GP of protection interval (GP) the reusable TDD system between up-downgoing; and in the compatible configuration mode of the non-TDD such as shown in Fig. 4-d; existence due to descending time slot does not meet the TDD configuration relation of standard definition, so reconfigurable GP.

Wherein, the descending time slot obtained on FDD UL carrier wave such as can adopt the following two kinds mode to the GP between ascending time slot:

First kind of way: one or more descending OFDM symbol and/or the upgoing O FDM symbol of putting sky (namely diging up) descending time slot and ascending time slot adjacent, to obtain the protection interval between descending time slot and ascending time slot.Such as under the scene shown in Fig. 4-d, base station can at FDD UL 20M frequency range small area C _p2the ending of descending sub frame part or the beginning of sub-frame of uplink part dig up part OFDM symbol, do downstream-to-upstream change-over time and be up to the GP of down conversion time, this GP also can as the interference avoided between base station and base station (interference between up-downgoing).This GP needs the macro base station considering N circle, if the radius of such as macrocell is R, so GP=N*2*R/C, C are the light velocity.

The second way: the descending time slot on FDD UL carrier wave frequency range or ascending time slot forward/the N number of OFDM symbol of rear skew, be used as GP with the N number of OFDM symbol vacated.

In above-mentioned two kinds of modes, the N number of symbol dug up or offset to configure, also can be the configuration mode of several regulations pre-set, base station can inform the corresponding configuration mode of subscriber equipment of its service or the index of configuration mode, and subscriber equipment knows GP configuring condition accordingly.

Adjustment scene (two):

Under such as scene shown in Fig. 4-e, Fig. 4-f, macro base station M1 adjusts macrocell C _m1the position of FDD sub-frame of uplink, make Pico base station P1 can the community C of newly deployed TDD compatibility mode _p2.

Wherein, the 0th, 1 and 5,6 work song frames in sub-frame of uplink corresponding to its part FDD uplink sub-carrier empty are put, so that Pico base station P1 is configured as neighbor cell C with macro base station M1 in Fig. 4-e and Fig. 4-f _p2descending sub frame be example, certainly also can be other the compatible cell configuration mode of TDD, configuration mode is similar, does not repeat one by one herein.

Under such as scene shown in Fig. 4-g and Fig. 4-h, macro base station M1 adjusts the position of sub-frame of uplink corresponding to the part FDD uplink band of macrocell Cm1, makes Pico base station P1 also can the community C of newly deployed non-TDD compatibility mode (flexible configuration pattern) _p2.Wherein, front four subframes in sub-frame of uplink corresponding to its part FDD uplink band empty are put, so that Pico base station P1 is configured as neighbor cell C with macro base station M1 in Fig. 4-g and Fig. 4-h _p2descending sub frame be example, certainly also can be other non-TDD cell configuration mode flexibly, configuration mode is similar, does not repeat one by one herein.

Meanwhile, in order to avoid community C _p1upstream data sends the upper community C to identical time slot _p2downlink data send interference, Pico community C _p1with Pico community C _p2upstream transmission time slot position corresponding to downlink transfer time slot can not send data, such as, shown in Fig. 4-e, Fig. 4-f, Fig. 4-g or Fig. 4-h.In order to support legacy version UE, putting on sky (diging up) time slot, can be able to send control signaling.If but the interval of two of correspondence uplink bands is comparatively large, then its interference can be ignored usually, now, Pico community C _p1with Pico community C _p2ascending time slot position corresponding to descending time slot can send data and upstream control signaling.

Further, if Pico community C _p2downlink transfer time slot and macrocell C with itself and adjacent frequency _m1upstream transmission time slot between there is the problem of interference, then macrocell C _m1go up and Pico community C _p2the upstream transmission time slot position of downlink transfer time slot adjacent frequency can not service data transmission, to avoid mutual interference, such as, shown in Fig. 4-f or Fig. 4-h.In order to support legacy version UE (namely not supporting the UE of this configuration mode), on the time slot putting sky (diging up), can be able to send control signaling.

For when transforming to the application scenarios of such as Fig. 4-e from Fig. 4-b, the proportioning change of TDD ascending-descending subframes different on macrocell and/or Pico community can (wherein, two sub-carrier wave frequency ranges calculate with 10 subframes respectively) as shown in table 4.

Further, eNB configuration update message or community activation message (message m s2) also can be carried: macro base station M1 adjusts macrocell C _m1the purposes information (such as indicate the access link for configuring Pico community or configure wireless backhaul link or energy-conservation configuration) of resource, and/or, macrocell C _m1the activationary time information etc. of resource adjustment.

Certainly, wherein one or more in above-mentioned information also can not be carried in eNB configuration update message or community activation message (message m s2), and default behavior can be adopted between base station to confirm corresponding configuration mode.Such as, if do not comprise macro base station M1 in indication information to adjust macrocell C _m1frequency point information, the macro base station M1 of resource adjust macrocell C _m1the bandwidth information of resource, now, macro base station M2 can be defaulted as macro base station M1 and adjust macrocell C _m1the frequency of resource is initial frequency corresponding to cell downlink frequency range, and macro base station M1 adjusts macrocell C _m1the bandwidth of resource is bandwidth corresponding to cell downlink frequency range, by that analogy.Or, also agreement can specify one or more fixing resources adjustment modes between base station, can the mode information of direct interaction resource adjustment or index information that only mutual resource adjustment mode is corresponding between base station, resource can be adjusted situation notice opposite end.Certainly, if only have a kind of resource to adjust mode, then notice opposite end whether adjustresources only can be needed.

Macro base station M2 can activate message (message m s2) according to eNB configuration update message or community, changes administrative community C _p2the up PRB configuration of neighbor cell, to avoid producing area interference.

Be appreciated that between macro base station M1, macro base station M2 and Pico base station P1, by interface direct between base station, such as X2, Iur, Iub or eat dishes without rice or wine; Or by indirectly interface, such as S1, Iu oral sex mutual information between base station.

206, macro base station M1 notice resides in community C _m1xia UE community C _m1configuration change;

Under a kind of application scenarios, macro base station M1 is in change or prepare change community C _m1ascending resource configuration time, if service part UE (such as the UE of R10 version) support community C _m1the configuration mode of this new UL subframe, and community C _m1when special HARQ feedback design is done in this new sub-frame of uplink configuration, macro base station M1 can eat dishes without rice or wine, with broadcast mode or mode of unicast, to redaction UE notifying cell C _m1uL subframe (time slot) configuration of change, and can not notify for the UE of legacy version.

Wherein, macro base station M1 can send service cell updating configuration information to the part or all of UE of its service, one or more of the following information of this service cell updating configuration information:

Adjust community C _m1up and/or the downlink frequency dot information of resource, adjust community C _m1up and/or the downlink bandwidth information of resource, adjustment community C _m1up and/or downstream position information, the community C of blank (mute) subframe after resource _m1the activationary time information of resource adjustment.

The Pico base station non-TDD of possible configuration is configured to the situation of compatible community, the eat dishes without rice or wine advice method of macro base station M1 to the UE of the redaction under it has broadcast mode (passing through system broadcast message) and mode of unicast (by dedicated signaling message).

Wherein, macro base station M1 notifies UE according to broadcast mode, and macro base station M1 can by community C _m1the configuration information of up mute subframe (time slot) be put on SIB2, its form can be as follows:

In addition, if use dedicated signaling notice UE, community C _m1the information of up-downgoing mute can transmit being carried in multiple descending signaling, such as beep-page message, connection establishment message, connect reconfiguration message, connection re-establishment message, in downstream message message transfer.

207, Pico base station P1 configures new Pico community C _p2;

Wherein, Pico base station P1 can according to macrocell C _m1there is provided ascending resource, and neighbor cell is to macrocell C _m1disturbance regime, determine to use macrocell C _m1the ascending resource provided disposes Pico community C _p2, new deployment Pico community C _p2can regard as and the resource of the wireless access links of community is configured to another kind from without being adjusted to or having adjusted to increase from one configuration.

New deployment Pico community C _p2ascending-descending subframes (time slot) proportioning:

Pico base station P1 can according to macrocell C _m1there is provided the number of sub frames of ascending resource and TDD cell configuration mode to mate, be met the Pico community C of TDD cell configuration mode _p2ratio of uplink subframe to downlink subframe.Or the process needs that Pico base station P1 also can dispatch according to HARQ time slot and up-downgoing, determine Pico community C _p2ascending-descending subframes (time slot) proportioning.

Main with by Pico community C below _p2being configured to the compatible allocating cell (namely Pico base station P1 newly disposes a TDD cell) of TDD for example is described, and by Pico community C _p2the situation being configured to the uplink-downlink configuration of the compatible allocating cell of a non-TDD (namely flexibly uplink-downlink configuration) is also similar.

For scene shown in Fig. 4-c, macrocell C _m1fDD UL 4 descending sub frames can be provided, because S subframe also regards descending sub frame as, so 4 descending sub frames that FDD UL is supplied to can be 2 DL subframes and 2 S subframes, also can be 3 DL subframes and 1 S subframe, the TDD now in corresponding table 2 be configured to configuration mode 0.Macro base station M1 then can according to the Pico community C of the configuration TDD of Pico base station _p2the position relationship of ascending-descending subframes (time slot), determine at macrocell C _m1which subframe (time slot) position of part or all of uplink band does not send business datum.

For (namely configuring the compatible allocating cell of non-TDD) when uplink-downlink configuration flexibly, Pico community C _p2the position of ascending-descending subframes can be decided by effective HARQ sequential.Such as FDD or TDD or FDD is in conjunction with TDD mode, or the sequential relationship of new definition.

Before this, hardware processing capability (comprising transmitting and receiving ability, such as transmitter number and/or receiver number etc.) that also can be respective alternately between base station, or unactivated incomplete community configured information.A community can be increased for base station and there is no the cell configuration ability of frequency spectrum resource, also can inform adjacent base station.This interactive information can send when inter-base station interface is set up, also can be mutual in follow-up interface signaling.

Such as, carrying out descending transmission to be supported in FDD UL frequency range, needing the transmission channel that increase by is new on this base station.If macro base station M1 (resource provides base station) knows that Pico base station P1 has the ability of newly-increased transmission channel, then macro base station M1 can send message to Pico base station P1 targetedly, provides the FDD UL resource of frequency range to it.

Can first configuration section community C on the P1 of Pico base station _p2information is (although community C _p2off-duty deactivation status is in before not configuring up-downgoing resource), and carry out alternately with adjacent base station (comprising macro base station M1 and macro base station M2), wherein, community C mutual between base station _p2partial configuration information can comprise one or more of following information:

Community C _p2physical-layer cell identifier, high layer cell identifiers, tracking area code, PLMN mark etc.;

Community C _p2mode of operation be tdd mode or fdd mode (optionally);

Community C _p2state when configuration (not be completely deactivation status).

In addition, if the hardware processing capability of not interacting base station between base station, then the base station of resource can be provided can to send FDD UL resource to part or all of adjacent base station information is provided, and the response that the adjacent base station with corresponding hardware processing capability may correspond to.

Under a kind of application scenarios, macro base station M1 (providing the base station of up FDD UL resource) sends eNB configuration update message (message m s1) to Pico base station P1 (receiving the base station of ascending resource), carries the macrocell C of the adjustment that macro base station M1 provides in eNB configuration update message _m1the configuration of FDD ascending resource, and the purposes indicating adjusted ascending resource.

In actual applications, macro base station M1 (donor base station) can in the FDD information in the service cell information of amendment in Article 1 eNB configuration update message (message m s1), send TDD cell concrete configuration to Pico base station P1, namely macro base station M1 determines that neighbor cell TDD configures, specifically can be as shown in table 6, but be not limited to this:

Table 6

Wherein, for the IE Muted UL config newly increased, its concrete configuration can be as shown in table 7, but be not limited to this:

Table 7

Or the configuration of muted subframe also can not use bitmap mode to indicate, but use corresponding TDD configuration mode instruction, namely indicate the one in TDD configuration 0 to TDD configuration 6.The time slot position that TDD descending sub frame is corresponding is exactly the macrocell C that macro base station M1 mute falls _m1the time slot position of UL subframe.

After adjacent Pico base station P1 receives the message of carrying above-mentioned configuration information, the reason that mute ascending resource configures if know to configure TDD access link, so Pico base station P1 can configure frequency and the bandwidth of TDD cell accordingly according to the up frequency in the up configuration of mute and bandwidth, in addition, if FDD UL resource community determines TDD cell configuration, then macro base station M1 can to the concrete time slot position comprising mute subframe in mute subframe configuration information.The neighbor cell of Pico base station P1 directly according to the time slot position of this mute subframe, can determine the up-downgoing proportioning of TDD cell and the original position of configuration.Then, P1 base station, Pico base station is the parameters such as this cell configuration ECGI, PCI, TAC, PLMN, and sends eNB configuration update message to adjacent base station.

In addition, in the mute ascending resource UL configuration information of macro base station M1 source eNB, Mute sub-frame configuration part only can also configure number of sub-frames, and concrete TDD cell configuration is decided by the Pico base station P1 of configuration TDD cell.

So, the concrete configuration of IE Muted UL config can be as shown in table 8, but be not limited to this:

Table 8

If according to the configuration mode shown in table 8, macro base station M1 can receive that Pico base station P1 sends comprise the eNB configuration update message of TDD cell configuration after, macrocell C is carried out in the position at the descending sub frame place of the TDD cell just configured according to Pico base station P1 _m1the non-scheduled operation (mute) of sub-frame of uplink.

Further, Pico base station P1 can carry the information of detailed new cell configuration in eNB configuration update message, such as, shown in table 9.
