With reference to figure 1, shown the diagrammatic sketch of structure of the wireless communication system of illustrated example.As shown in this Fig, system 100 comprises and is configured the base station 110 of communicating by letter with a plurality of travelling carriages 120.For example, being arranged to the travelling carriage 120 of radio communication, can be cellular phone, personal information manager (PIM or PDA) or the like.Should be noted that in fact these devices need not be " moving ", but can communicate by letter simply with base station 110 by Radio Link.Corresponding forward link (FL) channel transmission data is passed through to travelling carriage 120 in base station 110, and travelling carriage 120 arrives base station 110 by corresponding reverse link (RL) channel transmission data.
Should be noted that concerning this was open, the identical entry in the accompanying drawing can be trailed lowercase by identical Reference numeral and show, for example, 120a, 120b or the like.These can only be quoted by integral body by Reference numeral at this.
Yet, in fact, but the specific design marked change of base station 110 and travelling carriage 120, each is as the wireless transceiver that is used for by forward link and reverse link communication.Therefore, base station 110 has identical general structure with travelling carriage 120.This structure illustrates in Fig. 2.
With reference to figure 2, shown functional block diagram according to the basic structural components of an execution mode explanation wireless transceiver system.As shown in the drawing, system comprises transmission subsystem 222 and receiving subsystem 224, and wherein each is connected to antenna 226.Send subsystem 222 and receiving subsystem 224 and can integral body be called transceiver subsystem.Send subsystem 222 and receiving subsystem 224 and insert forward direction and reverse link by antenna 226.Send subsystem 222 and receiving subsystem 224 and also be connected to processor 228, this processor is configured to control and sends and receiving subsystem 222 and 224.Memory 230 is connected to processor 228 and thinks that processor provides service area and local memory.Data source 232 is connected to processor 228 to be provided for the data that system transmits.For example, data source 232 can comprise microphone or from the input of the network equipment.These data are handled by processor 228, are sent to the transmission subsystem 222 that transmits data by antenna 226 then.The data that receiving subsystem 224 receives by antenna 226 are forwarded to processor 228 and are used for handling, and are forwarded to data output 234 then and are used for expression to the user.Data output 234 can comprise such as loud speaker, visual display unit or arrive the equipment of the output of the network equipment.
Those skilled in the art of the present invention will recognize that the structure of describing among Fig. 2 is illustrative and other execution mode can use optional configuration.For example, processor 350 can be general purpose microprocessor, digital signal processor (DSP) or application specific processor, can carry out the function of some or all of transceiver other parts, or any other processing that is required by transceiver.Therefore, the scope in this additional claim is not restricted to concrete configuration described here.
Consider to be implemented in the structure of the Fig. 2 in the travelling carriage, the assembly of system can be regarded as being connected to the transceiver subsystem of processing subsystem, and wherein transceiver subsystem is responsible for receiving and to transmit data and processing subsystem by wireless channel and is responsible for preparing and providing data to transceiver subsystem and is used to transmit and receive and handles the data that obtain from transceiver subsystem.Transceiver subsystem can be considered and send subsystem 222, receiving subsystem 224 and antenna 226 to comprise.Processing subsystem can be considered to comprise processor 228, memory 230, data source 232 and data output 234.
As implied above, in fact the base station comprises different channels with communication link between the travelling carriage.With reference to figure 3, shown the diagrammatic sketch of a plurality of channels between explanation travelling carriage and the base station.As shown in FIG., base station 110 transfers data to travelling carriage 120 by one group of forward link channel 310.Typically, these channels comprise Traffic Channel and control channel, and data transmit by Traffic Channel, and control signal transmits by control channel.Each Traffic Channel has one or more relative control channels usually.For example, forward link channel 310 can comprise the forward fundamental channel (F-FCH) that can be used to transmit low speed data, and the forward complement channel (F-SCH) that can be used to high speed, point-to-point communication maybe can be used to the forward high-speed broadcast channel (F-HSBCH) of broadcast to a plurality of receivers.These channels also can comprise Forward Dedicated Control Channel (F-DCCH), forward broadcast control channel (F-BCCH) or the Forward Paging Channel (F-PCH) that can be used to transmit the control information relevant with the others of Traffic Channel or system operation.
Travelling carriage 120 transfers data to base station 110 by one group of reverse chain channel 320.In addition, typically, these channels comprise Traffic Channel and control channel.Travelling carriage 120 can send back the base station with data by channel, such as Reverse Access Channel (R-ACH), inverse expansion access channel (R-EACH), reverse request channel (R-REQCH), reverse enhanced supplemental channel (R-ESCH), Reverse Dedicated Control Channel (R-DCCH), reverse common control channel (R-CCCH) or reverse rate indicator channel (R-RICH).
In many cases, the disturbed restriction of reverse chain-circuit capacity.The base station according to service quality (QoS) demand assignment that is used for various travelling carriages can with reverse link communication resources to travelling carriage so that effectively utilization makes throughput-maximized.
Make the maximum using of reverse link communication resources comprise Several Factors.The factor that will consider is that each travelling carriage can experience the channel quality of variation at any given time from the mixing of the reverse link that the is scheduled transmission of different mobile stations.For increasing total throughout (by the data total amount of all travelling carriages transmission in the sub-district), as long as expectation is that whole reverse link just is fully utilized when having reverse link data to be transmitted.In order to fill up active volume, the flank speed that some travelling carriages can be allowed to can support with them inserts.Additional travelling carriage can be allowed to access up to reaching capacity.When which travelling carriage of decision scheduling, the data volume that maximum rate that each travelling carriage can support and each travelling carriage must transmit can thereby be considered in the base station.Can support the travelling carriage (considering the data volume that supported data rate of travelling carriage and travelling carriage must transmit) of bigger throughput can replace to support at present the optional travelling carriage of high-throughput more and selected.
Another factor that will consider is by each travelling carriage requested service quality.Can allow to postpone to insert a specific travelling carriage and can improve, and select to support the more travelling carriage of high-throughput with the channel of expectation travelling carriage (or more specifically, its supported throughput).Yet the situation that may occur is that the suboptimum travelling carriage may need to be allowed to access to allow travelling carriage to satisfy the minimum quality of service guarantees.Therefore, the data throughout of actual schedule may not be a bare maximum, but can come optimization according to channel condition, available travelling carriage delivering power, quality of service request and similar factor.
Various scheduling mechanisms can be used to allow travelling carriage to transmit data on reverse link.One class reverse link transmits and to comprise that travelling carriage makes request to transmit on reverse link.The base station determines whether available resources can adapt to this request and make permission to allow transmission by the base station.This permission is made clearly for single mobile station, and perhaps it can be the public permission to all travelling carriages.Alternatively, travelling carriage may not have sufficient data or channel quality determining a request, and can spontaneously transfer data to the base station.
One or more travelling carriages are arrived with the capacity allocation of reverse link in the base station.The travelling carriage that permission inserts is allowed to use the maximum power level that can transmit under the situation of permission.In one embodiment, reverse chain-circuit capacity utilizes service pilot (T/P) than distributing.Because the pilot signal of each travelling carriage is controlled adaptively by power and controlled, the T/P of appointment is used for transmitting at reverse link the available horsepower of data than expression.As implied above, indult can be carried out to one or more travelling carriages in the base station, expression is assigned to the T/P value of each travelling carriage, and can carry out public permission to the residue travelling carriage of asking to insert, and expression is permitted for the maximum T/P value that those residue travelling carriages transmit.
Traditionally, T/P is used to distribute reverse chain-circuit capacity to arrive different mobile stations, and does not consider the concrete channel by each travelling carriage use.In other words, in fact, power control is carried out based on each travelling carriage.In native system, the T/P ratio that is used for each channel between specific travelling carriage and the base station is included in Poewr control method, rather than only is used for the distribution between the travelling carriage.
With reference to figure 4 and Fig. 5, shown the flow chart that a method that execution mode adopts is described, this method power controlling is to the different channels between travelling carriage and the base station.Fig. 4 has described the method for using in conjunction with first channel, the power levels of both of wherein regulating first channel (Traffic Channel) and pilot channel.First and the power level of pilot channel increased simultaneously or reduced to keep the T/P ratio between them.Fig. 5 has described the method for using in conjunction with second channel, the power level of wherein not regulating second (business) and pilot channel, but the T/P ratio of adjusting second channel.Therefore, the power level of second channel is effectively regulated and is not influenced the power level of pilot channel.
In one embodiment, first channel is reverse link primary channel (R-FCH), and the power level and the pilot channel that are used for this channel are coordinated to regulate.This channel carries voice communications, this voice communication have typical most important property in wireless communication system (for example, cellular telephone system).Because the service level of this channel may be very strict, the basis of controlling as power with it can guarantee that service level will be satisfactory, although satisfied service level may not can be provided on all channels.
With reference to figure 4, determine also by receive frame data (square frame 410) earlier in the base station whether this frame comprises mistake (square frame 420) and carry out again for the power control of first channel.If this frame comprises mistake (square frame 430), then the power level of first channel is low excessively, should be increased with the power level of representing this channel and pilot channel to travelling carriage (square frame 440) so the base station sends a UP information.When this information was moved the platform reception, travelling carriage increased the power level (square frame 450) of first channel and pilot channel.If this frame does not comprise mistake (square frame 430), then the power level of first channel is that abundant height and base station send a DOWN information to travelling carriage (square frame 460), should be reduced with the power level of representing this channel and pilot channel.When this information was moved the platform reception, travelling carriage reduced the power level (square frame 470) of first channel and pilot channel.
When one of them channel receives mistake and when being necessary to send UP or DOWN message to travelling carriage, the amount that power level (or T/P than) is increased (going up rank) or reduces (following rank) can change with implementation.Typically, the amount that in fact is reduced of the amount that is increased of power level greater than power level.In an exemplary embodiment, pilot tone is carried out power control in conjunction with single Traffic Channel, and last rank have * value of dB, and time rank have */(1/FER-1) value, wherein FER is the frame error rate of pilot channel.Similarly, the T/P of each additional channel ratio can recruitment Y, and reduces with amount Y/ (1/FER-1), wherein the value of FER corresponding to T/P than the channel that is increased/reduces.
In execution mode, pilot tone is controlled by power in conjunction with a plurality of Traffic Channels, and the calculating on last rank and following rank may be had a few more complicated, although this not necessarily necessary situation.In a typical embodiment, last rank are chosen as the calculated maximum that goes up rank that is used for a plurality of channels.In this embodiment, following rank are chosen as the calculated minimum value on rank down that is used for a plurality of channels.In an optional execution mode, last rank can be chosen as the calculated minimum value that goes up rank that is used for a plurality of channels, and rank are chosen as the calculated maximum on rank down that is used for a plurality of channels down.And in another embodiment, last rank are chosen as the calculated maximum that goes up rank that is used for a plurality of channels, and rank are calculated as the calculated rank sum down that is used for a plurality of channels down.In one embodiment, final pilot adjustment is calculated as rank and following rank sum.In another embodiment, final pilot adjustment is further quantized to limited level and is sent to travelling carriage with signal.And in another embodiment, quantize to have two-stage, have fixed amount up or down.
With reference to figure 5, determine also by receive frame data (square frame 510) again in the base station whether received frame comprises mistake (square frame 520) and be performed again for the power control of second channel.If this frame comprises mistake (square frame 530), T/P is than being increased (square frame 540), the current T/P value of each travelling carriage that this base station maintain is used to communicate with by the base station.Message is sent to travelling carriage to represent new T/P value (square frame 560) from the base station then.Travelling carriage is provided with the power level of second channel according to new T/P then.Be different from the flow chart of Fig. 4, pilot power level is not influenced by mistake, this mistake be second channel experience or the variation that in T/P, causes.If this frame does not comprise mistake (square frame 530), the T/P ratio is reduced (square frame 550), and corresponding message is sent to travelling carriage (square frame 560).In addition, new T/P does not influence the power level of pilot signal.
The effect of the method for describing among Fig. 4 illustrates in Fig. 6.Fig. 6 is the diagrammatic sketch of the relative power level of explanation first channel and pilot channel.The diagrammatic sketch of Fig. 6 has shown the function of the power level of these channels as the time.The power level of first channel is indicated by Reference numeral 610, and the power level of pilot channel is indicated by Reference numeral 620.The power level of curve 610 is proportional to the power level of curve 620 as can be seen.It is constant that the ratio of curve (T/P) keeps.When the power level of curve when the moment, t1 was reduced, it is constant that the ratio of curve keeps.In other words, before moment t1 and afterwards, T/P is than identical (that is to say that T/P equals T '/P ').
The effect of the method for describing among Fig. 5 illustrates in Fig. 7.This figure is the diagrammatic sketch of the relative power level of explanation second channel and pilot channel.710 curves of corresponding second channel power level are proportional to the curve 720 of corresponding pilot channel power level, but when being necessary to reduce the power level of second channel (for example, at moment t2), pilot power level is not affected.Therefore, though curve before moment t2 and proportional afterwards, the ratio of curve has changed (that is to say that T/P is not equal to T '/P ').
By realizing on segregated channel that as described above power control, the power level of these channels and/or T/P specific energy have certain independence ground optimization each other.In one embodiment, one of them channel can be optimised by the power level of regulating channel and pilot channel simultaneously, and the residue channel can be by regulating their T/P separately than being optimised.In another embodiment, one group of channel carries out power control simultaneously in conjunction with pilot tone, and another organizes the power level of regulating its T/P ratio and not influencing pilot tone or first group of channel.
Then, travelling carriage can determine whether at each channel transmission data, and selects suitable delivering power, data rate and be used for other parameters of these transmission.Travelling carriage can comprise different considerations to the selection that passes a parameter.For example, as mentioned above, whether travelling carriage can be the stand-by period trade off throughput and uses spontaneous transmission (autonomous transfer) to transmit data with decision.In other words, travelling carriage can transmit at once to reduce the stand-by period, maybe can ask the transmission of higher rate and wait for a public permission or indult.In addition, the maximum T/P that given travelling carriage is allowed to transmit, travelling carriage selecting data speed (being no more than the T/P of permission) is to be suitable for being transmitted the stand-by period of data and/or the demand of throughput.
Can support different throughput level with the different travelling carriage of base station communication.This situation may be owing to the diverse location of travelling carriage in the sub-district, with different speed move, and the channel condition that changes of experience cause.The throughput that can be moved the platform support also can be moved platform to be influenced the selection of various transmission characteristics, such as delivering power, transfer rate and modulation format.Travelling carriage can be based on many factors to the selection of these characteristics.For example, transfer rate can be increased (by reducing encoding rate, increase symbol rate or using the more modulation scheme of high-order) to increase data throughout.
Another factor is the power of travelling carriage.Travelling carriage has limited amount available transmit power.Because data transfer rate is directly related with delivering power, the transfer rate of travelling carriage can be moved the max power constraint of platform amplifier.Available then travelling carriage amount of transmission power can be assigned to one or more pilot channels, one or more data channel and any other relevant control channel.For effectively, relevant pilot channel must be received reliably so that the phase reference of modulation usefulness to be provided.Therefore, a part of available transmit power is assigned to pilot tone, and increases that part of reliability that will increase pilot reception.Yet, increase that part of available transmit power that is assigned to pilot tone and also reduced to can be used for the quantity of power that data transmit, and reduce that part of available transmit power that is assigned to data and also reduced the modulation reliability.But, for any given T/P ratio, suitable modulation format and transfer rate can be determined.
The travelling carriage delivering power also can by BTS management with avoid and other travelling carriage between too much interference, by using power control and various data transmission dispatching technique.Power control is used to reverse link signal is maintained the level that is suitable for the base station.The base station receives pilot signal and controls the power level of travelling carriage so that the pilot power approximately equal that receives from each travelling carriage from each travelling carriage.Because pilot level is roughly the same for each travelling carriage, the T/P that is used for travelling carriage is than the index that becomes the message capacity of being used by travelling carriage during reverse link transmits.The T/P ratio was determined in the base station for each travelling carriage after, travelling carriage can suitably select delivering power, transfer rate and modulation format with in the T/P ratio that rests on permission subsequently.
