Describe in detail

The detailed description of setting forth below in conjunction with accompanying drawing is intended to the description as various configurations, and is not intended to only configuration that expression can be put into practice notion described herein.This detailed description comprises that detail provides the thorough to each conception of species.Yet it will be apparent to those skilled in the art that does not have these details can put into practice these notions yet.In some instances, well-known structure and assembly are shown so that avoid falling into oblivion this genus with the block diagram form.

Example telecommunications system

Forward Fig. 1 now to, show the block diagram of the example of explaining orally telecommunication system 100.Each conception of species that provides in the whole text in the disclosure can be striden miscellaneous telecommunication system, the network architecture and communication standard and realized.And non-limiting, the each side of explaining orally among Fig. 1 of the present disclosure is that the UMTS system of adopting by reference TD-SCDMA standard provides as an example.In this example, the UMTS system comprises that (for example, UTRAN), it provides various wireless services such as comprising phone, video, data, information receiving, broadcasting and/or other services to radio access network (RAN) 102.RAN 102 can be divided into such as radio network sub-system (RNS) several RNS 107, and each RNS is by controlling such as the RNC of radio network controller (RNC) 106.For the sake of clarity, RNC 106 and RNS 107 only are shown; Yet except RNC106 and RNS 107, RAN 102 also can comprise any number RNC and RNS.RNC 106 is devices of especially being responsible for assigning, reshuffle and discharging the radio resource in the RNS 107.RNC 106 can be through using any suitable transmission network to interconnect to other RNC (not shown) among the RAN 102 such as direct physical connection, virtual network or suchlike various types of interface.

The geographic area that is covered by RNS 107 can be divided into several cellular cells, wherein each cellular cell of radio transceiver device service.Radio transceiver device is commonly called the B node in UMTS uses, but also can be called base station (BS), basic transceiver station (BTS), radio base station, wireless set, transceiver function, Basic Service Set (BSS), extended service set (ESS), access point (AP) or other certain suitable terms by those skilled in the art.For the sake of clarity, show two B nodes 108; Yet RNS 107 can comprise any number wireless B node.B node 108 provides to the WAP of core net 104 for any number mobile device.The example of mobile device comprises cell phone, smart phone, Session Initiation Protocol phone, laptop devices, notebook, net book, intelligence basis, PDA(Personal Digital Assistant), satelline radio, global positioning system (GPS) equipment, multimedia equipment, video equipment, digital audio-frequency player (for example, MP3 player), camera, game console or any other similar function device.Mobile device is commonly called subscriber's installation (UE) in UMTS uses, but also can be called mobile radio station (MS), subscriber station, mobile unit, subscriber unit, radio-cell, remote unit, mobile device, wireless device, Wireless Telecom Equipment, remote equipment, mobile subscriber station, access terminal (AT), portable terminal, wireless terminal, remote terminal, hand-held set, terminal, user agent, mobile client, client or other certain suitable terms by those skilled in the art.In order to explain orally purpose, three UE 110 are shown are in B node 108 and communicate by letter.The down link (DL) that also is called as forward link is meant the communication link from the B node to UE, and the up link (UL) that also is called as reverse link is meant from the communication link of UE to B node.

As shown in the figure, core net 104 comprises the GSM core net.Yet, as those skilled in the art will recognize that, each conception of species that provides in the whole text in the disclosure can realize in RAN or other suitable Access Networks, so that the access to the core net of the other types except that the GSM network to be provided to UE.

In this example, core net 104 usefulness mobile switching centres (MSC) 112 come the support circuit-switched service with gateway MSC (GMSC) 114.One or more RNC such as RNC 106 can be connected to MSC 112.MSC 112 is devices that route and UE mobility functions were set up, called out to controlling call.MSC 112 also comprises Visitor Location Register (VLR) (not shown), the information relevant with the subscriber during it comprises UE and is in the area of coverage of MSC 112.GMSC 114 provides the gateway through MSC 112, for UE place in circuit switching network 116.GMSC 114 comprises attaching position register (HLR) (not shown), and HLR comprises the subscriber data such as the data of the details that reflect the service that the specific user has subscribed to.HLR also is associated with the authentication center (AuC) that comprises because of the different verify data of subscriber.When the calling that receives to particular UE, GMSC 114 inquiry HLR give the specific MSC of this position of service with the position of confirming this UE and with call forward.

Core net 104 also uses Serving GPRS Support Node (SGSN) 118 and Gateway GPRS Support Node (GGSN) 120 to support packet data service.Represent the GPRS of General Packet Radio Service to be designed to packet data service to be provided than the available higher speed of speed of standard GSM circuit switched data service.GGSN 120 provides the connection to packet-based network 122 for RAN 102.Packet-based network 122 can be internet, proprietary data net or other certain suitable packet-based network.The major function of GGSN 120 is to UE 110 packet-based network connectivty to be provided.Packet is transmitted between GGSN 120 and UE 110 through SGSN 118, and the function that this SGSN 118 carries out in packet-based territory and MSC 112 carries out in circuit commutative field is identical functions fundamentally.

The UMTS air interface is spread spectrum direct sequence CDMA (DS-CDMA) system.Spread spectrum DS-CDMA expands to user data on the much wide bandwidth through multiply by the sequence with the pseudo-random bits that is called chip.The TD-SCDMA standard is based on this type of direct sequence spread spectrum skill, and requires time division duplex (TDD) in addition, but not as in the UMTS/W-CDMA of numerous fdd modes system used FDD (FDD).Both use identical carrier frequency to TDD to the up link (UL) between B node 108 and the UE 110 and down link (DL), but up link and downlink transmission are divided in the different time-gap of carrier wave.

Example TD-SCDMA frame structure

Fig. 4 has explained orally example TD SDMA (TD-SCDMA) frame 400 according to some aspect of the present disclosure.Described like above frame structure 200 to Fig. 2, TD-SCDMA frame 400 can for example comprise the 10ms frame that is subdivided into two 5ms subframes 204.

Each subframe 204 can comprise that seven are used for the traffic time slot (TS) 420 that up link (UL) is communicated by letter with down link (DL).TD-SCDMA be based on that time-division and sign indicating number divide to allow a plurality of UE can share identical radio bandwidth.Down link is shared identical bandwidth with ul transmissions in different TS.In each time slot, a plurality of yards channels are arranged.For example, as shown in Figure 4, have 1 DL time slot (TS0), succeeded by 3 UL time slots (TS1-TS3), again succeeded by 3 DL time slots (TS4-TS6).Typically, TS0 is allocated for overhead channel (for example, P-CCPCH, S-CCPCH, PICH etc.), and TS1-T6 is allocated for traffic channel (for example, DPCH, HS-PDSCH, E-PUCH).As shown in Figure 4, TS0 can be assigned and be used for down link and can pass on such as broadcast channel control messages such as (BCH), and TS1 can be allocated for up link.

204 li of each subframes, possibly exist 2 switching points that up link and down link are separated (otherwise from up link convert into down link and).First switching point can be positioned at down link pilot timeslot (DwPTS) 206 and protection period (GP) 208 places of uplink pilot time slot (UpPTS) between 210.Second switching point can occur in TS1 ending end up with TS6 between Anywhere.Second switching point can determine the traffic essence of specific sub-frame, and it can be a symmetry or asymmetrical.In asymmetric mode, at least one uplink time slot and a downlink time slots can be allocated for traffic.As shown in Figure 4, regardless of asymmetric degree maybe, DwPTS 206, GP 208 and UpPTS 210 can be between TS0 and TS1.

DwPTS 206 can be used for downlink synchronization.GP 208 can determine maximum cellular cell size.Base when UpPTS 210 can be used for confirming from the receiving power level and receive of UE by the B node.As shown in Figure 4, each time slot 420 can comprise 2 data fields 212.Midamble 214 can and be used as training sequence between these two data fields 212 to carry out channel estimating, power measurement and synchronous.

Insert in (HSDPA) agreement 3 physical channels capable of using in the TD-SCDMA high-speed downlink packet: carry the High-Speed Shared Control Channel (HS-SCCH) of the High-Speed Physical Downlink Shared Channel (HS-PDSCH) of user data paroxysm, the modulation of carrying the data paroxysm that is used for HS-PDSCH and encoding scheme and channel code and time interval resource information and carry HS-PDSCH channel transmitted quality index (CQI) and the high-speed shared information channel (HS-SICH) of mixed automatic repeat request (HARQ) ACK/NACK (really receiving/negative true the receipts).

On the other hand; In the TD-SCDMA High Speed Uplink Packet inserted (HSUPA) agreement, 4 physical channels capable of using: the E-DCH hybrid ARQ that the E-DCH that carry enhancement type special channel (E-DCH) the physical uplink link channel (E-PUCH) of UL data paroxysm, when the E-PUCH resource is unavailable, carries the related UL control of E-DCH signaling inserts uplink control channel (E-RUCCH) at random, carry the E-DCH absolute grant channel (E-AGCH) of up link absolute grant control information and carry HARQ ACK/NACK was really received indicator channel (E-HICH).

Fractional frequency reuse

Fig. 5 has explained orally the example arrangement that belongs to the cellular cell that adjoins the B node.Each cellular cell can have the interior section 502 near the B node.Each cellular cell also can have the exterior section 504 that also is called as the cellular cell edge.

Common problem can appear when subscriber's installation (UE) is positioned at cellular cell edge (for example, externally part 504 places).In cellular cell edge, compare and to increase when down link (DL) or up link (UL) interference are positioned near B node (for example, in interior section 502) with UE.Interference typically is owing to the crossover signal from adjacent cells causes.A solution is to use more sane forward error correction (FEC) scheme and spreading factor is increased to SF=16.Yet using FEC not close in this way needs.

According to each side of the present disclosure, can control interference through using higher frequency re-use factor=2 or 3.As UE during, conventional frequency re-use factor=1 is used in transmission more near the B node.This is called as fractional frequency reuse.As shown in Figure 5; In the interior section 502 of cellular cell; But frequency of utilization F1, but in the exterior section 504 of cellular cell, can under the situation of the space reuse factor＞1, (for example reuse this frequency; A cellular cell can use F3 in its exterior section 502, and another adjoins cellular cell and can in its exterior section 502, use F2).

Such fractional frequency reuse can reduce the interference of cellular cell edge.Additional benefits is that owing to the SINR (signal to interference and noise ratio) that improves the hard success rate of transferring can be able to increase.This possibly be useful for depend on the system that hard transfer and relay transfer such as TD-SCDMA etc. for.According to each side of the present disclosure, the technology and the device that allow and/or support the fractional frequency reuse in the TD-SCDMA system are provided.In some aspects, the performance of cellular cell edge and transfer can improve.

The resource of TD-SCDMA system can be time slot or frequency.According to some aspect, some time slots and/or frequency can be allocated to and allow the space reuse factor＞1, and all the other time slots and/or frequency can be allocated to permission reuse factor=1.The interior zone of cellular cell does not produce interference probably, and therefore identical time slot and/or frequency can be used for these interior zones.Adjustable power does not produce interference to guarantee inner cellular cell.Yet identical time slot and frequency should roughly do not shared in the perimeter of cellular cell.In other words, outside cellular cell is assigned to different time slots and/or different frequencies probably.

As an example, Fig. 6 has explained orally the situation of having only a frequency.For example, cellular cell 1 is assigned with TS0 and is used for the traffic channel operation that overhead channel, TS1 and TS4 are used for interior zone 602, and TS3 and TS6 are used for the traffic channel operation of perimeter 604.Cellular cell 2 is assigned with TS0 and is used for the traffic channel operation that overhead channel, TS1 and TS4 are used for interior zone 606, and TS2 and TS5 are used for the traffic channel operation of perimeter 608.Therefore, tolerance frequency reuse factor=2 are used for perimeter 604,608.

In the situation of multiple radio frequency cellular cell, resource can be striden the static or dynamically distribution of frequency.Fig. 7 has explained orally the example allocation to 3 frequency carriers.Each can have following public distribution in the

cellular cell

1,2 and 3: the TS0 of all 3 frequencies is used for the overhead channel, and the TS1 of all 3 frequencies, TS2, TS4 and TS5 are used for the traffic channel operation of interior zone 702.In addition, each has different branches and is used in perimeter operation in the

cellular cell

1,2 and 3.Cellular cell 1 can be assigned with the TS3 of frequency 1 and the operation of traffic channel that TS6 is used for perimeter 704.Cellular cell 2 can be assigned with the TS3 of frequency 2 and the operation of traffic channel that TS6 is used for perimeter 706.Cellular cell 3 can be assigned with the TS3 of frequency 3 and the operation of traffic channel that TS6 is used for perimeter 708.Thus, according to some aspect, each in the perimeter of these cellular cells has the different time slot of frequency, and can support frequency re-use factor=3 to be used for the perimeter of cellular cell.

In other respects, striding time slot that cellular cell change is used for same frequency possibly close and need.As long as the exterior section of cellular cell is not shared the identical time slot (except overhead signal) that same frequency is arranged, the interference between the adjacent cells just can be eliminated.

Another aspect of the present disclosure is explained orally in Fig. 8.Each can have following public distribution in the

cellular cell

1,2 and 3: TS0 is used for the overhead channel, and the TS1 of all 3 frequencies and TS4 are used for the traffic channel operation of inner cellular cell 802.TS2, TS3, TS5 and the TS6 that cellular cell 1 can be assigned with frequency 1 is used for the traffic channel operation of perimeter 804.TS2, TS3, TS5 and the TS6 that cellular cell 2 can be assigned with frequency 2 is used for the traffic channel operation of perimeter 806.TS2, TS3, TS5 and the TS6 that cellular cell 3 can be assigned with frequency 3 is used for the traffic channel operation of perimeter 808.

According to some aspect, can be depending on inner cellular cell zone and come dynamically Resources allocation than the regional resource requirement of outside cellular cell.For example, if just communication and less relatively UE is just communicating by letter in interior zone in the perimeter of many UE is arranged, then resource allocation can make more multi-slot and/or frequency can supply in these perimeters, to use.The example that has the distribution that is beneficial to the zone use of outside cellular cell is shown in Fig. 8.Similarly, if just communication and less relatively UE is just communicating by letter in the perimeter in interior zone of many UE is arranged, then resource allocation can make more multi-slot and/or frequency can supply in these interior zones, to use.The example that has the distribution that is beneficial to the zone use of inner cellular cell is shown in Fig. 7.According to some aspect,, then resource allocation can be changed so that the time slot and/or the frequency that increase can supply to use in the needs part if the relative number of the UE that the UE that in interior zone, operates operates in the zone externally changes significantly.

Resource changing

Otherwise when UE when the cellular cell zone moves on to outside cellular cell zone internally or, network can distribute different resources (that is, UE possibly switch to interior zone or perimeter institute's distributed time slot and/or frequency, depends on the circumstances).In order to trigger this change, network can order UE to provide to have certain internal measurement report: T of following report quality or other parameters _ADV, it is by time difference T _RX-T _TXThe Timing Advance of definition.Fig. 9 shows this parameter.T _RXThe 902nd, the zero-time of first uplink time slot in first subframe of being used by UE is calculated together with base according to the UE of the reception of the beginning of certain downlink time slots the time.T _TXThe 904th, calculate from the zero-time of the same uplink time slot of UE.For example, if UE in UL transmission fully synchronously, T then _ADV906 come down to postpone (RTD) with the round trip of B node, and it is with proportional to the distance of B node.

Special parameter T _hCan be designated as and be used for detecting the threshold value that UE is in inner cellular cell zone or outside cellular cell zone.According to some aspect of the present disclosure, UE can be configured to report T _ADVMeasure.For example, UE can be configured at T _ADV＞T _hIn (that is, UE traverses to outside cellular cell zone in the cellular cell zone internally) time, report.UE also can be configured at T _ADV＜T _hIn (that is, UE traverses to inner cellular cell zone from outside cellular cell zone) time, report.

Figure 10 A has explained orally according to the B node of some aspect of the present disclosure and the exchange of the example between the UE.The B node can transmit measuring control signal 1002 and measure with configuration UE and report T _ADVOtherwise if UE not internally the cellular cell zone be transformed into outside cellular cell zone or (that is, if T _ADVNot with threshold value T _ADV=T _hIntersect), then communicating by letter 1004 can exchange on existing institute Resources allocation.When the B node detects the UE position and between interior zone and perimeter, changes based on measurement report 1006; The B node can use physical channel reconfiguration message or radio bearer reconfiguration signal 1008 to reconfigure DPCH (DPCH), to try hard to redistribute correspondent frequency space reuse factor resource.UE available signal 1010 subsequently confirms the completion that resource is redistributed.Communication 1012 can exchange on time of redistributing and/or frequency resource subsequently.

Figure 10 B has explained orally according to the another kind of example exchange between the B node of some aspect of the present disclosure and the UE.For example, UE can operate under HSDPA, and perhaps in other words, UE is just receiving the paroxysm of DL high-speed data on HS-PDSCH (High-Speed Physical Downlink Shared Channel) 1016.Similarly, UE can operate under HSUPA, and promptly UE is just transmitting the paroxysm of high speed UL data on E-PUCH (enhancement type special channel physical uplink link channel) 1018.As described above, the B node can transmit measuring control signal 1002 and measure with configuration UE and report T _ADVIf T _ADVNot with threshold value T _ADV=T _hIntersect, then communicating by

letter

1016,1018 can exchange according to the frequency and the time resource that are used HS-SCCH (High-Speed Shared Control Channel) or E-AGCH (enhancement type special channel absolute grant channel) 1014 to distribute by the B node.Receiving report T _ADVWith threshold value T _ADV=T _hAfter the measurement report 1006 that intersects, the B node can use HS-SCCH or E-AGCH 1020 the data paroxysm to be distributed to the new time slot of different frequency reuse factor.For example communicate by letter and 1022 and 1024 can exchange according to deallocated resources subsequently.

Thus, according to each side of the present disclosure, for time slot/frequency resource allocation provides the frequency space to reuse so that the cellular cell edge performance can be improved and strengthen the transfer performance in the TD-SCDMA system.
