The coded data that is used for each data flow can be multiplexed by using the OFDM technology to come with pilot data.The given data pattern that pilot data is normally handled in a known way, and can be used for assessing channel response at the receiver system place.Then the multiplexed pilot tone and the coded data that are used for each data flow are modulated (that is sign map) so that modulation symbol to be provided based on the certain modulation schemes of selecting at each data flow (for example, BPSK, QPSK, M-PSK or M-QAM).Can be identified for data rate, coding and the modulation of each data flow by the instruction that processor 230 is provided.In certain embodiments, the number of parallel spatial stream can change according to the class information from user's emission.
The modulation symbol that then will be used for all data flow is provided to TX MIMO processor 220, and it can further handle modulation symbol (for example, at OFDM).TX MIMO processor 220 is then with N TIndividual symbols streams is provided to N TIndividual reflector (TMTR) 222a is to 222t.In certain embodiments, TX MIMO processor 220 according to described subscriber channel response message based on to the user of emission symbol and the antenna of therefrom launching symbol come symbol to data flow to apply wave beam to form flexible strategy.
Each reflector 222a receives and handles respective symbol stream so that one or more analog signals to be provided to 222t, and further described analog signal is regulated (for example, amplification, filtration and up-conversion) so that the modulation signal that is suitable for via the mimo channel emission to be provided.Then respectively from N TIndividual antenna 224a launches from the N of reflector 222a to 222t to 224t TIndividual modulation signal.
At receiver system 250 places, the modulation signal of being launched is by N RIndividual antenna 252a receives to 252r, and will be provided to corresponding receiver (RCVR) 254 from line 252 received signal every day.254 pairs of corresponding received signals of each receiver are regulated (for example, filtration, amplification and down converted), described conditioning signal is carried out digitlization so that sample to be provided, and further handle described sample so that corresponding " reception " symbols streams to be provided.
RX data processor 260 is then from N RIndividual receiver 254 receives described N RIndividual receiving symbol flows, and based on specific receiver treatment technology it is handled so that the Grade numbers of " detection " symbols streams to be provided.The processing that RX data processor 260 is done hereinafter is described in further detail.Each detected symbol stream comprises the symbol as the assessment of the modulation symbol of launching at respective stream of data.RX data processor 260 then carries out demodulation, release of an interleave and decoding to each detected symbol stream, to recover the business datum of described data flow.The processing complementation that the TX MIMO processor 220 at processing that RX data processor 260 is done and ejector system 210 places and TX data processor 214 are performed.
At ejector system 210 places, receive, regulate, handle by demodulator 240 demodulation and by RX data processor 242, by antenna 224 to recover the CQI that receiver system is reported by receiver 222 from the modulation signal of receiver system 250.Then the CQI that is reported is provided to processor 230, and in order to (1) definite data rate and the coding and modulation scheme that will be used for described data flow, and (2) produce the various controls at TX data processor 214 and TX MIMO processor 220.
In the multi-address radio communication system 200 of Fig. 2, TX data processor 214 associative processors 230 and memory 232 can be operated to determine the number corresponding to the scheduling beep-page message of receiver system in the overlay area 250.TX data processor 214 can be configured to produce hashed value at each scheduling receiver system 250 based on unique identifier that accesses terminal.TX data processor 214 can produce Quick Paging message, and it comprises the number of the receiver system of being discerned in the described Quick Paging message 250 and dispatches the hashed value of receiver system 250 corresponding to each.
Each receiver system 250 can be operated to receive Quick Paging message and to recover the respective Hash value.RX processor 260 associative processors 270 and memory 272 can determine whether any hashed value in the Quick Paging message discerns receiver system 250.If it is discerned by hashed value, receiver system 250 can monitor beep-page message so.Perhaps, if its hashed value is not included in the Quick Paging message, receiver system 250 can be converted to resting state and can wait for next scheduling Quick Paging message so.
Fig. 3 is the simplification functional-block diagram of embodiment that is used to produce and launches the system 300 of beep-page message.Described system 300 can be the part of ejector system of (for example) Fig. 2 or the part of access point shown in Figure 1.
The simplification functional-block diagram of Fig. 3 only illustrates a part that is associated with generation and emission Quick Paging message in the described system.Simplify functional-block diagram for example do not show with generation or mapping and Quick Paging message in the related blocks such as piece that are associated of the beep-page message that is associated of accessing terminal discerned, and do not have displaying to being sent to scheduling, processing and the emission of the data, information or other business that access terminal.
300 embodiment of system of Fig. 3 comprise timing and synchronization module 302, and it is coupled to scheduler 304.Scheduler 304 is coupled to Quick Paging message generator 310, and the generation of initial Quick Paging message.Quick Paging message generator 310 is coupled to encoder 320 with Quick Paging message according to circumstances.The Quick Paging message that encoder 320 operations are encoded with generation with the position of coding Quick Paging message.TX MIMO processor 330 is coupled in described coding output.TX MIMO processor 330 couples a signal to transmitter stage 340, and described transmitter stage 340 uses antenna 344 to transmit.
The timing of position, frame, piece or bag that timing and synchronization module 302 tracking systems 300 receive and produce.In one embodiment, timing and synchronization module 302 are kept bit synchronization, and the position that makes system 300 be produced has the roughly the same cycle.Timing and synchronization module 302 also can be synchronously and tracking groove and frame timing, and wherein each frame comprises the position of predetermined number.In ofdm system, groove can comprise one or more OFDM symbols, and frame can comprise one or more grooves.
Superframe can comprise the frame of predetermined number.In addition, the concrete frame in the superframe can be exclusively used in customizing messages.For instance, each superframe can comprise have predetermined length (for example six frames or six OFDM symbols) leading.
Superframe preamble can be used for filling all broadcast channels that access terminal in the overlay area that is transmitted into access point.A part of superframe preamble can be assigned to the quick paging channel (QPCH) that is used to pass on Quick Paging message.For instance, Quick Paging message can be frame or the OFDM symbol in the superframe preamble.The length of superframe preamble can be static or can change based on the size of the block of information of distributing to Quick Paging message.
In one embodiment, distribute to Quick Paging message the position number be static.In another embodiment, the number that divides the position task Quick Paging message is dynamic, and determines based on the number that accesses terminal that need notify in Quick Paging message to small part.Number in the position of distributing to Quick Paging message is under the dynamic situation, and system 300 can distribute many positions by selecting one in the predetermined group packet length.Perhaps, system 300 can be configured in preset range or with the form that increases progressively single position Quick Paging message be distributed in the position of any number.
System 300 can be configured to send the size of Quick Paging message in the field of described message or certain other message.In one embodiment, system 300 does not send the size of Quick Paging message and depends on receiver and determines the bag size.
Timing and synchronization module 302 are coupled to scheduler 304.Scheduler 304 tracking communication links and system 300 are with the information of emission, and part is dispatched described information based on system timing.In one embodiment, scheduler 304 determines that wireless communication systems are just attempting to be in accessing terminal of idle state and to set up active communications session with current.
Quick Paging message generator 310 determines that according to scheduler 304 in the overlay area of dispatching patchers 300 which accesses terminal paging receiving message.Quick Paging message generator 310 comprises beep-page message counter 312, identification hash generator 314 and message assembler 316 access terminal.
Beep-page message counter 312 is determined through scheduling with the number in the current superframe or the access terminal paging message of launching during other Quick Paging cycle based on scheduler 304.Beep-page message counter 312 is determined through the different number that access terminal of scheduling with paging receiving message.Owing to multiple reason, can in Quick Paging message generator 310, use this number.
Among the adjustable length embodiment of Quick Paging message, the number of being notified in the Quick Paging message that accesses terminal can be indicated the length of Quick Paging message, and described number can be included in the field of Quick Paging message therein.The length of Quick Paging message is among the embodiment of static state therein, is used for can changing based on the number of being notified in Quick Paging message that accesses terminal at the number of the position that the identification of Quick Paging message accesses terminal.The number of being notified in the Quick Paging message that accesses terminal can be included in the mode to inform that the identification that accesses terminal accesses terminal in the field of Quick Paging message.
The identifier that accesses terminal hash (ATIH) generator 314 is configured to produce the compressed version of identifier of accessing terminal.Though following examples are described as hash function with compression function, but in fact ATIH generator 314 can be the compression identifier generator of any kind, and can use any mapping or the algorithm that produce less bits to compress ATI value or certain other identifier that accesses terminal.
Each accesses terminal and has the unique identifier that is called the identifier that accesses terminal (ATI).If the ATI that accesses terminal is carried in the beep-page message, accesses terminal so and know that network has data to send.
ATIH generator 314 is configured to determine the N position hash (being called ATIH) (for example, ATIH=HashFunction (ATI)) of ATI.In certain embodiments, ATI can be 48 to 128 long, and N can be 8.ATI may not be unique to the mapping of ATIH, because ATIH generator 314 may be compressed into ATI the representation with less bits.To be mapped to the number of the potential access terminal AT I value of same ATIH to decrement (also the being called compression ratio) influence of ATI execution.
ATIH generator 314 can keep one or more ATIH values, and making does not have the ATI value to be mapped to the ATIH value that is kept.For instance, ATIH generator 314 can be left zero ATIH value, so that any situation that accesses terminal will not be notified in indication.Can come ATIH generator 314 is guaranteed will be mapped to null value unintentionally without any access terminal AT I value by keeping zero ATIH value.
If the ATIH that accesses terminal is carried in the Quick Paging message, access terminal so and determine that network has paging and will send, and the supervision beep-page message that accesses terminal is checked the paging that is directed to it.On the contrary, if ATIH does not carry in Quick Paging message, access terminal so and can save power and can change into and change low power sleep state into by reading gating message not.
Accessing terminal two differences has under the situation of identical ATIH, and ATI can cause the Quick Paging conflict to the not exclusive mapping of ATIH value.Under this type of situation, included not exclusive ATIH causes to access terminal more than one and monitors described beep-page message in the Quick Paging message, but only at a beep-page message that accesses terminal with described ATIH value.For instance, if ATIH generator 314 produces identical ATIH at two different access terminal AT 1 with AT2, and this ATIH is carried in the Quick Paging message, and AT1 and AT2 all will monitor beep-page message so.Yet it is not paging at AT2 that actual beep-page message may only contain at AT1.
Among the adjustable length embodiment of Quick Paging message, ATTH generator 314 produces the ATIH value according to pre-defined algorithm therein.ATIH generator 314 accesses terminal at each that will notify in Quick Paging message and produces ATIH corresponding to ATI.May there be physical constraints to the length of Quick Paging message.Therefore, system 300 can define can be in Quick Paging message clear and definite the accessing terminal of maximum number of identification.
The length of Quick Paging message is that ATIH generator 314 parts produce the ATIH value based on the number that accesses terminal that will notify among the embodiment of static state in Quick Paging message therein.ATIH generator 314 is carried out the variable compressive of ATI value, and compression ratio changes according to the number of notifying in the Quick Paging message that accesses terminal at least.When notifying less accessing terminal in Quick Paging message, the ATIH generator uses than little compressible so that the possibility of minimizing Quick Paging conflict may be favourable.In some cases, ATIH generator 314 does not even need to compress the ATI value, and ATI can be identical value with ATIH.Along with the number that accesses terminal notified in the Quick Paging message increases, ATIH generator 314 can increase compression ratio, makes that the total number that is used to discern the position that accesses terminal in the Quick Paging message is approximate identical.
For instance, system 300 can be to the position of Quick Paging distribution of messages fixed number N QP_BLKIn addition, the specific fields that is exclusively used in the ATIH value in the Quick Paging message can have maximum length, for example 35.If beep-page message counter 312 determines to have only one to access terminal and need notify in Quick Paging message, ATIH generator 314 can produce to have and be less than or equal to 35 ATIH so.If beep-page message counter 312 is determined to notify two to access terminal, ATIH can be configured to produce each and has the ATIH value that is not more than 17 so.Similarly, access terminal in order to notify three in Quick Paging message, ATIH generator 314 produces each and has the ATIH value that is not more than 11.May there be physical constraints to ATIH generator 314 applied compression ratios.Therefore, system 300 can be provided with the maximum number that accesses terminal that can clearly discern in Quick Paging message.
As mentioned above, no matter Quick Paging message has car space or distance to go, system 300 can define the maximum number that accesses terminal that can clearly discern in Quick Paging message.That is to say, can send Quick Paging message via quick paging channel with limited capacity (for example, Q position).Can have some examples like this, wherein the beep-page message counter 312 definite numbers that access terminal that will notify are greater than the maximum number that can clearly notify.In this type of situation, Quick Paging message can comprise that there is the field than the Quick Paging that the manys notice that can contain in the Quick Paging message in identification.This field can be described as " more " or " extra identifier " fields.

ATIH generator 314 can be configured to produce the ATIH value that is less than or equal to maximum number.In one embodiment, ATIH generator 314 produces the ATIH value for having accessing terminal of minimum ATIH value.In another embodiment, ATIH generator 314 produces the ATIH value for all of dispatching at beep-page message access terminal, and another module determines which ATIH value is in order to fill Quick Paging message.
316 operations of message assembler are with the Quick Paging message that collects based on beep-page message counter 312 determined numbers.Message assembler 316 is filled the field of discerning the number that accesses terminal.If the number that accesses terminal is greater than pre-determined maximum number, 316 uses of message assembler are corresponding to the value of maximum number so.
Message assembler 316 is also filled the ATIH field that identification accesses terminal in the Quick Paging message.If the number that accesses terminal that will notify in Quick Paging message is less than or equal to maximum number (comprising zero), 316 series connection of message assembler are corresponding to the ATIH value that accesses terminal so.Message assembler 316 is removed " more " fields, and described " more " fields can be single positions.
If the number that accesses terminal that will notify in Quick Paging message is greater than maximum number, the ATIH value of the maximum number from minimum ATIH value, selected of message assembler 316 series connection so.Message assembler 316 can sort to the ATIH value, and fills Quick Paging message with the order that increases the ATIH value.Message assembler 316 is concluded " more " fields.
Message assembler 316 can be to the zero padding of Quick Paging message or is otherwise filled, so that obtain required message-length.The number of notifying in according to Quick Paging message at ATIH generator 314 that accesses terminal and producing under the situation of different ATIH values, message assembler 316 can be to the zero padding of Quick Paging message to provide consistent Quick Paging message-length.
