Embodiment
Its structure of the mobile communication system of representing among Fig. 1 is corresponding to known GSM mobile radio telephone network, and it has a plurality of mobile MSC of central office, base station controller BSC, base station BS and mobile radio station MS and at least one OMC operation and maintenance centre OMC.The mobile MSC of central office is networking or set up the alternative communication network inlet of a fixed network PSTN for example mutually.In addition, these move the MSC of central office each are connected with a base stations control BSC at least.And each base station controller BSC can be connected with a base station BS at least.Such base station BS is a radio station, and it can set up, remove and keep one or more dedicated radio link to mobile radio station MS by a radio interface.For example the OMC operation and maintenance centre OMC that connects on a base station controller BSC is embodied as mobile radio telephone network or is the control of its network equipment and maintenance function.The function of this structure is not limited to described gsm system, and can migrate on other mobile communication system, makes the present invention also can use those places.
Fig. 1 example of passing the imperial examinations at the provincial level illustrates 3 dedicated radio link, both is used between 3 mobile radio station MS and base station BS descending also at uplink direction defeated useful information ni, for example voice or data message or signaling information.Being transmitted in the point-to-point connection of useful information ni realized whereby.Base station BS is connected with antenna equipment AE, and it for example is made up of 3 single irradiators.Each single irradiator is in a regional interior orientation emission of the radio plot that service is provided by base station BS.Can use also in principle that single irradiator of greater number-by using adaptive antenna, it produces controlled width of cloth ejected wave lobe on the locus of mobile radio station MS.For transmission useful information ni,, can realize capacity gain-adaptive antenna gain thus by the quantity of point-to-point connection higher under constant bandwidth.Radio technical resources is better used.
Outside useful information ni, from base station BS return mobile radio station MS on point-to-multipoint connects-in case of necessity constantly-organizational information oi is provided.This organizational information oi comprises recognition network for example, stays the essential information of district (LA, the band of position) and radio plot (CI, cell identification), but also relevant for the available transmission channel of base station BS with about the information of the frequency of adjacent radio cells.This moment, organizational information oi was at the logical transport channel-control channel of regulation-for example have frequency channels (FCCH, the FREQUENCY CONTROL channel) and the radio broadcasting channel of synchronizing channel (SCH) (BCCH, Broadcast Control Channel) or Common Control Channel (CCCH) on down direction, send and receive.Theaomni-directional transmission when realizing organizational information oi by all single transmit devices of antenna equipment AE.
Having communicating to connect of useful information ni and organizational information oi between base station BS and mobile radio station MS suffers to propagate by the subsidiary multichannel on direct propagation path that for example produces in the reflection on the building.Compare the big antenna gain of generation with theaomni-directional transmission by the directional transmissions of useful information ni on the regulation single transmit device of antenna equipment.The quality that communicates to connect is improved by directional transmissions, realizes but can only can not connect point-to-multipoint point-to-point connection in known mobile communication system.
If from the motion of mobile radio station MS, then multichannel is propagated and can be caused in the signal component of the different propagation paths of the mobile radio station MS place information signal that receives overlapping in time together with other interference.The task of base station BS and base station controller BSC is, payment organizational information oi less antenna gain during theaomni-directional transmission on down direction is so that can realize as far as possible efficiently and economically using radio resource under constant bandwidth.Should not surpass total transmitting power this moment for the transmission channel of transmission organizational information oi.
Fig. 2 represents by having bandwidth B, for example B=16MHz or B=2MHz, the frame structure of radio interface transport information.Here, this radio interface has a time-division multiplex (TDMA) or frequency multiplexing (FDMA) component and a Code Division Multiplex component.Preference information transmission according to the present invention for example with TDMA and CDMA component to the TDMA/CDMA mobile radio communicaltions system in conjunction with explanation, but also can use the various combinations of above-mentioned multiple cut-in method.Can provide more multiband-its not single illustrating in Fig. 2 for mobile radio communicaltions system.
The TDMA component comprises a time shaft t, it one for example by 8 time slot ts1, ts2 ... so segmentation in the time frame of composition makes message transmission carry out with radio blocks (pulse train).The FDMA component comprise one have by a plurality of frequency channels FK1, FK2 ... the frequency axis f of the frequency frame of composition.Time slot or frequency channels constitute transmission channel, are included in the useful information of a plurality of connections between mobile radio station and the base station in it simultaneously at every turn.Here, each radio blocks, the useful information ni that comprises in a transmission channel UEK who is made of for example time slot t2 can distinguish to c8 by means of the extended code c1 according to the CDMA component on code axle c.Extended code c1 constitutes the fine texture that connects special use to c8, uses this fine texture can transmit maximum 8 the parallel subscriber signals of mobile radio station in this example simultaneously.Useful information for the signal of composition data, voice and signaling preferably uses standardized extended method.Carry out a kind of power adjustments for the useful information ni in this connection, this adjusting depends on each that measure and received power signalling on relevant mobile radio station and base station BS.For the total transmitting power of emission information in each time slot is constant.
Be transmission organizational information oi on down direction simultaneously, in system, prepare or select a transmission channel UEKS, set up time slot ts1 for it in this example or another selectable scheme is frequency channels FK1.Transmission channel UEKS with organizational information oi preferably always is present in first time slot of a tdma frame or multiframe.But the linking number that has useful information ni in transmission channel UEKS reduces than the maximum number of transmission channel, reduces to 6 connections from 8 connections altogether in this example.The useful information ni of 6 connections of this reservation is distinguished from each other to c6 by extended code c1 with the same usually.The useful information ni that all the other two connections exist is in due form replaced by organizational information oi is some or all of at least, and is logged in selected transmission channel UEKS.Only be used to transmit organizational information oi at a kind of UEKS of this transmission channel in particular cases, no longer comprise useful information.
For the following realization power adjustments of the organizational information oi in transmission channel UEKS, promptly it is preferably constant transmitted power emission and transmission with one, and this power is than being each the transmitting power height that has with the connection of information ni.Connection by reducing useful information can corresponding raising organizational information transmitting power, but keep total transmitting power constant.This means that the transmitter antenna gain (dBi) during theaomni-directional transmission organizational information oi-this just can realize during usually only in single connection on a point-to-multipoint connects as antenna equipment using adaptive antenna, needn't improve total transmitting power of selected transmission channel.Its advantage is, the increase of the connection by while providing organization's information or the number of mobile radio station and capacity gain under constant bandwidth on the radio interface.Consequently for the efficient and economic message transmission of organizational information, it should provide use for mobile radio station as much as possible in by the radio plot of base station services.Radio technical resources is performed well in useful information transmission and organizational information transmission.
Data d-voice, data or the signaling of useful information ni-expansion and data oia, the oiB of organizational information oi, the expansion of oid realize according to Fig. 2.Here, data oia, oiB, oid represent different organizational informations, for example the organizational information of being prepared by different control channels (seeing top Fig. 1).They preferably time-division multiplex be included among the transmission channel UEKS of rather than a plurality of selections.For useful information ni, each data symbol d is represented to Q6 with Q1 by the spreading factor of the number of chips definition of each data symbol with the execution of extended code c1 in the c6 this moment.The spreading factor Q1 of first subscriber signal for example equals 3.Extended code c1 repeats to data symbol d ground from data symbol d.The expansion of the data oia of organizational information oi, oiB, oid can realize according to DS-CDMA method (direct sequence), this moment this data symbol symbol perdurabgility for example greater than symbol perdurabgility of the data d of useful information ni.The DS extended code is continuous extended code, represents with Q7 and Q8, and it is greater than the extended code of useful information ni.For the length of the chip of expansion useful information ni and organizational information oi equates.Also can abandon the expansion of organizational information oi, use because it can unify to offer a plurality of mobile radio stations.It inserts among the transmission channel UEKS of selection and the transmitting power transmission to improve simply under this kind situation.If in selected transmission channel UEKS, outside organizational information oi, exist without any useful information ni, then can be in this example the power of this channel improve 8 times-come theaomni-directional transmission information corresponding to 9dB-.
Fig. 3 represents the structure according to base station controller BSC in the mobile communication system of Fig. 1 and base station BS.Base station controller BSC has signal handling equipment SP, for example digital signal processor and have assembled unit MUX and the control appliance ST of selected cell AUS.Assembled unit MUX is used to make up from signal handling equipment SP for transmitting the signal of ready useful information ni and the signal of organizational information oi at down direction.Selected cell AUS is that pure useful information transmission distributes transmission channel UEK or is the transmission distribution transmission channel UEKS of organizational information oi, and is additional in case of necessity with useful information ni.
In the multiplexing equipment of assembled unit MUX, 8 of a plurality of communicating to connect-mostly be most in this example-subscriber signal distribute to a time slot.By in signal handling equipment SP, expanding useful information ni, in assembled unit MUX, produce the signal that is superimposed as a public broadband signal with the extended code of distributing.For tissue receiving information advantageously reduces the linking number that has useful information, arrange and carry out by unit equipment MUX by control appliance ST.
Be the suitable transmission channel UEK/UEKS informing base station BS of message transmission, this base station has the transmitting apparatus SE of a band power control unit LS and transmission unit UE.Carry out the conversion to analog high frequency in the unit of in the end mentioning, its modulated and amplification is as sending signal tx by antenna equipment AE emission.Power control unit LS is adjusted to the transmitted power that improves to mobile radio station transmission organizational information, and this depends on the number that reduces connection when having with information and realizes.For total transmitted power of the transmission channel of the selection that preferably makes up by time slot remains unchanged, perhaps less under the best circumstances.
Fig. 4 represents the structure of used mobile radio station MS.The received signal rx that receives from antenna equipment AE amplifies among the high frequency unit HF of transmission unit UE of transmitting apparatus in corresponding to the base station at one, converts base band and demodulation to.Received signal converts for example digitized symbol with discrete deposit value in analog to digital converter ADC.Coupling device KE connection mode number converter ADC and signal handling equipment SP, the latter are included as according to JD method (joint-detection) as digital signal processor and better detect JD processor JD-P of useful information ni and for detecting the RAKE receiver of organizational information oi.
Detect parallel carrying out, this moment, signal handling equipment SP used extended code known in receiver relevant with the data of the useful information ni (see figure 2) that receives, so that reduce the bandwidth of received signal and the gap of amplifying signal level and noise level.With this Data Detection because interference unit or under the strong jamming between the signal, also can carry out.RAKE receiver RAKE is measured as the received power of organizational information oi in mobile radio station MS, and use it as decision to another cell switch be the reference of power adjustments.
