Description

The system and method for link and MAC layer transaction complete process

It is 60/085,752 interests that this application requires in the U.S. Provisional Application sequence number of on May 17th, 1998 application, and its title is the system and method for media interviews control in the wireless data communication system.

The present invention relates to the complete process of link and media access layer transaction in the communication system, be specifically related to this process in the time slot communication system.

It is that the sum of errors loss that is used for data communication system recovers that link layer recovers agreement.Because the loss and the error characteristics of especially severe in the link, it is important especially that link layer recovers for radio communication.

(for example, IS-130), supervisory frame normally exchanges between the peer-entities of the radio link protocol that connects and cut off (RLP) for honeycomb fashion circuit data system.Do not provide connection duration or last effective order to count the motor-driven RLP of reception of anticipatory knowledge.It is that similarly protocol status remained on during the cycle of non-activity that mobile data link protocol (MDLP) operates among the CDPD.

The grouped data transaction often has sudden, has long non-activity between each transaction.For have the long internal affairs processing time intermittence transaction mobile radio station for, (even each transaction can relate to mass data shift), keeping the RLP state information in long free time is that very less efficiently utilizes Internet resources.In addition, exchange utilizes valuable air interface resource between the supervisory frame that is used to cut off, and may cause setting up some additional delay of new connection.So efficient fast, moderately end transaction is handled and is sought after, particularly when link layer protocol does not turn back in this network.GSM General Packet Radio Service (GPRS) adopts diverse ways.Under the GPRS situation, the position is retained in each radio link control (RLC) piece, in order that point out the end of Temporary Block Flow.This additional overhead is inefficient for long transaction in each RLC piece, causes some losses of the handling capacity that may have.The objective of the invention is to overcome, or reduce the effect of above-mentioned one or more problems at least.

According to the present invention, provide a kind of system and method that is used for implementing the radio link protocol complete process towards the packet data communication system of transaction.The step that this method comprises has: utilize MAC layer controller specified data backlog and transmission to comprise the BEGIN protocol Data Unit of sign (transaction size indicating device) to receiver.This method is further comprising the steps of: start the transmission of MAC layer transaction with response BEGIN PDU.

Still according to the present invention, a kind of packet data communication system towards transaction is described.This system comprises: the MAC layer controller is used for determining MAC layer buffer data backlog; With the MAC layer transmitter, be used for transmission and comprise the BEGIN protocol Data Unit of sign (transaction size indicating device) to receiver.This system also comprises a kind of device, is used to start the transmission of MAC layer transaction with response BEGIN protocol Data Unit.

When description was of the present invention, this application utilized media interviews controls (MAC) layer hypothesis, and it is based on the model of OSI(Open Systems Interconnection).OSI is the standard card cage of communicating by letter between the different system of accepting in the world by different sellers' manufacturings.The main communication protocol of the current great majority that adopt has the structure based on osi model.Osi model is organized into 7 different classes to communication process, this 7 class be placed on based on the hierarchical sequence of customer relationship on.Layer 7 to layer 4 is handled end-to-end communication information source and message destination.And layer 3 to layer 1 is handled access to netwoks.

Layer 1, physical layer is handled the physical unit of sending data by circuit, that is, and electricity, machinery and control data circuit function.Layer 2, data link layer, the process and the agreement of processing operational communications circuit.Layer 3, network layer, determination data are how to shift between the computer and route between each network internal and network.

We know that Packet Data Channel can be supported multiple modulation.MAC layer with layer 3 all frame is provided, and they have been transformed into the byte stream that utilizes delimiter.Radio link protocol (RLP) also is referred to as to retransmit link protocol, is used for transfer layer 2 all frames between sub-district and mobile radio station, and vice versa.The byte stream of layer 3 is segmented into all frames of RLP, and the sliding window re-transmission scheme is used for sending in order and recovering.

MAC layer transaction preferably transmitted from the BEGIN frame.On up link and down link, the MAC layer converts layer 3 all frame to byte stream, and this byte stream is assembled into a series of CONTINUE frames.The last new data subframe of transaction utilizes the END frame to send.

The BEGIN frame of each transaction be stop with standby mode under utilize 4 level modulation technology to send so that obtain confirming from receiver.After receiving the BEGIN frame, receiver initialization RLP.Also utilize BEGIN frame initialization section echo (PE) to be used for transaction, in that transaction, determine the operational mode of follow-up automatic re-send request may (ARQ) pattern CONTINUE frame.

On up link and down link, the operational mode of two kinds of possible ARQ pattern CONTINUE frames is arranged.First kind is incremental redundancy degree (pattern 0), and second kind is regular coding (pattern 1).We know that pattern 0 and pattern 1 can adopt fixed modulation or Adaptive Modulation.

Mistake in the ARQ check transmission data.Transmitter is based on error detection occurs (check) field in the content encoding transmission data of this message.Receiver then recomputates the check field, and it and the check field that receives are compared.If two check field unanimities then send ACK (affirmation) to transmitter.If two check fields are inconsistent, then return NAK (negative acknowledgment) transmitter and retransmit this message.

For the transmission of up link and down link, provide the bitmap feedback of ARQ stastus format.In addition, on the basis of each time slot, provide the ACK/NAK feedback to be used for the transmission of up link.

Fig. 1 represents the high-level block diagram according to operation on the Packet Data Channel 100 of the present invention.Drawn towards the packet data communication system 105 of transaction, its middle level 3 all frames 110 offer the layer 2 at transmitter 120 places, MAC layer 115, and convert the byte stream that utilizes boundary sign to.This just allows MAC layer 115 unified connecting gear to be provided for different layer 3 agreements.This byte stream is segmented into rlp frame, and distributes a frame sequence number (FSN).FSN does not send clearly as the rlp frame of part.

For under arbitrary pattern than high throughput, according to layer 2 backlog with from the knowledge of the channel-quality feedback 130 of receiver 135, layer 1125 data conversion become to be selected from 4 grades, 8 grades, or the symbol of 16 grades of modulation.Channel quality is to use through the signal of the physical layer of receiver 135 decoder input in 2 140 on the layer and the ratio of interference and noise Measure.Decoder 140 output layers 3 all frames 150 then.

The moving station mark symbol that the utilization of IS-136 digital control channel is interim also is referred to as part echo (PE).Suppose that PE is abridged mobile station identity (MSID), that is, be used as PE for last 7 of MSID.Because this mechanism, two or more active users use the probability of identical PE very big, because mobile device can not correctly be differentiated their PE, with regard to the protocol status that often leads to errors.

In Fig. 2, this probability tables is shown as the function of while active user number on this channel.In packet data application (opposite with speech or circuit data applications), the possibility of sharing same channel at 10 of any given times or more active users is very big.In these cases, the probability that the part echo repeats reaches 25% and Geng Gao, and this is that correct system's operation is unacceptable.

This problem is resolved selectively, PE value by distributing a suggestion (for example, dynamic PE) or effectively mobile device identity (AMI) is given each mobile device, is used for the down link transaction and be used for need be more than the up link transaction of single character group.Down link transaction and up link transaction all are the MAC layer transaction of part.AMI is launched machine and receiver and is using on specific Packet Data Channel during the transaction as unique (distribution) local identifier.New AMI distributes to each new transaction, has therefore eliminated potential ambiguity.Same AMI can be used for any direction (that is, it is to be started by up link or down link that AMI distributes, and no matter which begins earlier, and before the both direction DTD, maintenance is always distributed).

When identifying a transmission opportunity,, just start new transaction if transmission buffer comprises new data.Down link can be ACK or NAK, but up link ACK always.Preferably, each MAC layer transaction is from BEGIN protocol Data Unit (PDU) handshaking, carries out with a series of CONTINUE PDUs transmission.BEGINPDU comprises the part Echo Rating of suggestion and/or the operational mode of suggestion.ARQ pattern CONTINUE PDUs can send with incremental redundancy degree pattern (pattern 0) or regular coding pattern (pattern 1), and the ARQ process of two kinds of patterns is different.Monitor that ARQ status PDU s is the periodic feedback that is used for providing accepting state to transmitter.

BEGIN PDU shake hands (that is, the ACK of BEGIN PDU shift) set up the operational mode of AMI and follow-up CONTINUE PDUs.We know that on multi-rate channel, realizing distributing mutually also is to use selectively.

Base station (also being referred to as the sub-district) starts the transaction of down link selectively by the transmission of BEGIN PDU.The parameter that BEGIN PDU represents comprises: mobile station identity (MSID); The ARQ pattern represents that this transaction is ACK or NAK actually; The search pointer (PI) that is used for the ACK transaction, whether expression needs mobile radio station to provide ACK through the ARQ status PDU; Distribute to the AMI value of mobile radio station; Mode indicator (MI) represents that follow-up down link CONTINUE PDU is regular coding or incremental redundancy degree actually; Distribute (PA) the subsequent data transfer phase on expression up link or the down link mutually.

If AMI is distributed to mobile radio station, identical AMI value is just distributed in the base station in BEGIN PDU.If mobile radio station does not have available AMI, the AMI value is just chosen randomly in the base station from the value that group allows, and utilizes BEGIN PDU that it is distributed to mobile radio station.The base station transmit control device under mode designated (IR or FC) in BEGIN PDU transmission initialization RLP.After receiving BEGIN PDU, mobile radio station receives controller initialization equity RLP under mode designated.

Fig. 3 represents the example device of 155 layers of the controls of media interviews in the duplex wireless data communication system (MAC).MAC 155 and layer 3160 (network layer), physical layer (layer 1) 165 (it comprises MAC layer transmitter 166 and MAC layer receiver 167) and management entities 170.In this example, MAC 155 provides data and quickens the control delivery service to layer 3160 and other higher layer entities more.MAC 155 utilizes layer 1 165, sends its PDU through MAC layer transmitter 166 by radio interface 175.Management entity 170 initialization stop, and suspend the operation of recovery and managing MAC 155.Management entity 170 is also monitored the mistake of MAC 155.Management entity 170 also provides dynamic PE management, is used for the packet data communication system 105 of Fig. 1 towards transaction.MAC 155 comprises two service access points (SAP): the SAP1 and the SAP0 that is used for expedited data and control that are used for regular data.Each SAP has corresponding transmission buffer (TXB), and sectionalizer (SGM) removes sectionalizer (DSGM), extractor (FRX), and transmission control unit (TCU) (TC).From the PDUs of different transmission control unit (TCU)s (also being referred to as the ARQ engine) TC0 and TC1, and provide the order of priority scheduling among channel access manager (CAM) 180 multiplexed Fig. 3.CAM 180 also is responsible for the random access of up link.MAC subchannel controller (SCC) 185, preferably up to 9 (SCC0 to SCC8), control is by the transmission of each wireless data subchannel.The overall MAC of MAC layer controller (MLC) 190 controls disposes and is connected with management entity 170.PDU encoder (PENC0 and PENC1) and decoder (PDEC0 and PDEC1) provide the channel coding/decoding of MAC PDUs under pattern 0 (incremental redundancy degree) or pattern 1 (regular coding).Pattern 0 section encoder (SENC0) and decoder (SDEC0) provide coding/decoding under the incremental redundancy degree pattern of transmission, interleaving/de-interleaving, and piecemeal/go piecemeal (blocking/deblocking).

MAC transmission control unit (TCU) (TC) internal structure of mobile radio station in Fig. 4 presentation graphs 3 is positioned at Fig. 1 MAC layer 2115 inside of transmitter 120.Transmission control unit (TCU) 192 is made up of following sub-piece: transmit control device (TCTX) 195 receives controller (TCRX) 200, broadcasting controller (TCB) 205, and router (TCRT) 210.Transmit control device 195 is connected to sectionalizer (SGM0 of Fig. 3 and SGM1), PDU encoder (PENC0 and PENC1), and CAM 180, the TCRT 210 of MLC 190 and Fig. 4.TCRX 200 and TCB 205 controllers are connected to sectionalizer (DSGM of Fig. 3), the MLC 190 of Fig. 4 and TCRT 210.TCRT 210 is connected to the TCTX 195 of Fig. 3, and TCRX 200, TCB205, MLC 190 and PDU decoder (PDEC0 and PDEC1).

Fig. 5 is the route treatment state figure that describes mobile radio station transmission control unit (TCU) 192 among Fig. 4.The router two 10 of Fig. 4 preferably shifts the frame of decoding to suitable process (send, receive or the broadcasting controller) in transmission control unit (TCU) 192.Had better adopt router two 10 with receiving control information, for example, distribute mutually, inquiry indication, broadcasting change notice and page or leaf indication continuously, can send to mobile device selectively by the reciprocity transmission control unit (TCU) that is positioned at the place, base station.Router two 10 tracking mobile stations are at the sleep state 215 of Fig. 5 or wake-up states 220 actually, and whether AMI has distributed to mobile device actually.We know, and are relevant with various conditions, and the router two 10 of Fig. 4 is the frame that receives of route correspondingly.

Router two 10 receives the frame of decoding through data.ind () primitive from the CAM 180 of Fig. 3.The router two 10 of Fig. 4 can be moved on to wake-up states 220 and returns through wake.req () and sleep.req () primitive respectively from the sleep state 215 of Fig. 5 by the MLC 190 of Fig. 3.The router two 10 of Fig. 4 sends the reception of data.ind () primitive to Fig. 4, sends or broadcasting controller (TCRX 200, TCTX 195 and TCB 205).Router two 10 notifies relevant page or leaf of the MLC190 of Fig. 3 or page or leaf to receive (through wake.ind ()) continuously, and broadcasting changes notice and receives (through bcn.ind ()) and new distribution mutually (through phase.ind ()/phase.req ()).

The transmit control device 192 of Fig. 6 key diagram 4 and the CAM 180 of Fig. 3 and the idle condition reciprocation of PDU encoder (PENC0 or PENC1).Fig. 6 illustrates that also carries out the transition to an example of waiting for distribution state.

In Fig. 6, the piece that transmits in the retrieval BEGIN PDU process preferably the up link transaction begin carry out, in order that the end that retrieve data and determine whether based on the size of transaction should Executive Office be managed from sectionalizer (SGM0 of Fig. 3 or SGM1).

When transmission opportunity occurring on the up link, the transmit control device 192 of Fig. 4 receives poll.ind () primitive from the CAM180 of Fig. 3.The transmit control device 192 of Fig. 4 points out with the response of poll.res () primitive whether this process can send data selectively.In idle condition, the TCTX195 of Fig. 4 sends BEGIN or ARQ STATUS PDUs.If the CAM 180 of Fig. 3 provides transmission opportunity this TCTX 195 to Fig. 4, then TCTX 195 responds with poll.con () primitive.TCTX 195 constructs a PDU and this PDU is delivered to the PDU encoder through data.req (), if be BEGIN PDU, just enters the wait distribution state.When the data of retrieval TCTX 195, TCTX192 calculates the number of data block in the buffer (TXB0 or TXB1), and determines from beginning it just should is that end (NB-Tx＜NB-Max and End-Tx-Flag=True) or this transaction of transaction should be from beginning with regard to unrestricted (NB-Tx=NB-Max and End-Tx-Flag=False).If the TCTX 195 of Fig. 4 just should be the end of transaction from beginning, the TS among the BEGIN PDU (transaction size) field just is arranged to the size of transaction in the data block, otherwise is arranged to NB-Max (maximum of NB-Max is 63).As an example of data block format, the escape sequence that this data block is stipulated from RFC 1662 begins, and it is at IETF RFC 1662, and " ppp in the class HDLC framing " described in one literary composition July in 1994, is incorporated in that this is for reference.

The transmit control device 192 of the Fig. 4 that describes in Fig. 7 presentation graphs 6 and the CAM 180 of Fig. 3 and the wait distribution state reciprocation of PENC1.Fig. 7 also describes new data block process and the retrieval ARQ state bitmap process calculated.The each execution when calculating new data block process, the TCTX 195 of Fig. 4 was preferably never by sending in the air, and still can be included in selectively in the current transaction.Retrieval ARQ state bitmap process relates to and the communicating by letter of the reception controller (TCRX) 200 of Fig. 4, and to retrieve a bitmap, this bitmap is pointed out the ARQ protocol status of down link transaction.

When transmission opportunity appeared at up link, transmit control device 192 received poll.ind () from the CAM180 of Fig. 3.The transmit control device 192 of Fig. 4 is with poll.res () primitive response, points out that transmit control device 192 can send data selectively.In waiting for distribution state, TCTX195 can send ARQ STATUS PDUs (if being inquired about by reciprocity transmission control unit (TCU) 192) selectively.If the CAM 180 of Fig. 3 provides the TCTX 195 of transmission opportunity to Fig. 4, then the CAM 180 of Fig. 3 sends poll.con () primitive.The TCTX195 retrieval ARQ state bitmap of Fig. 4 is constructed a PDU, gives PDU encoder this PDU through data.req ().When calculating new data block, the TCTX 195 of Fig. 4 at first checks the end (End-Tx-Flag=True) that has arrived current transaction whether.If this situation, 195 of TCTX calculate the piece of retaining, and until current end of transaction (representing with BST-Status), and ignore the data that end of transaction may arrive buffer (TBX0 among Fig. 3 or TBX1) afterwards.If not this situation, the MAC buffer of the TCTX195 calculating chart 3 of Fig. 4, all data (representing) among TXB0 or the TXB1 with BST-Status and TXB-Status sum.If the new piece number of pressing this method calculating is greater than NB-Max, then transaction can continue as unrestricted selectively.Otherwise need terminal procedure.

Fig. 8 represents the free time, waits the transition between underway of transaction under to be allocated and pattern 0 and pattern 1 state.Receive through PCF (as being that the True situation is by shown in the data.con () primitive) according to CAM and Error=Null condition just confirming its BEGIN PDU after or distribute (as (ARQ-Status-Rx) primitive and condition WAI and AMI=AMI-Idle are shown in the False according to the data.ind () of TCRT 200) receiving downlink ARQstatus PDU with AMI after, the TCTX 195 of Fig. 4 can be selectively from waiting for that distribution state carry out the transition to one of underway state of transaction (depending on the uplink mode of negotiating with the base station (UL-pattern)).Waiting for distribution state, timer T-WAT and BOFF-START can cancel selectively and TCTX195 can transit back idle condition selectively.Before the permission mobile radio station repeated its access attempts, these timers specified this mobile radio station should wait for the time quantum that distributes through the AMI/Mode of ARQ Staus PDU.

In the underway state of transaction (pattern 0 and pattern 1), TCTX 195 can be selectively through PCF (data.con () of CAM 180 in according to Fig. 3) with through ARQ StatusPDU (data.ind () of TCRT 200 in according to Fig. 4) confirmation of receipt.If send table 230 sky among Figure 12, there are not new data (not having the data backlog) to send (NB-Tx＜=0), just finish transaction, the TCTX 195 of Fig. 4 carries out the transition to idle condition selectively.Otherwise TCTX195 remains on the underway state of transaction, unless non-activity timer (T-INAC) cancels.

Fig. 9 describes the underway state of transaction, sees Fig. 8, the reciprocation between the transmit control device 192 of Fig. 4 and the CAM 180 of Fig. 3 and the PDU encoder (PENC0 or PENC1 among Fig. 3).Fig. 9 also describes the process that finds retransmitted data blocks.This process is carried out at every turn selectively, and the TCTX 195 of Fig. 4 determines in the transmission table 230 of Figure 12 whether any data block is arranged, and these data blocks also are not received the machine affirmation and can retransmit (that is the data backlog, is arranged).

When transmission opportunity when up link occurs, transmit control device 192 receives poll.ind () primitive from the CAM180 of Fig. 3.Transmit control device 192 points out whether can maybe must send data with the response of poll.res () primitive.At the underway state of transaction, the TCTX195 of Fig. 4 can send ARQ STATUS (if being inquired about by reciprocity transmission control unit (TCU)) or CONTINUE PDUs selectively.If the CAM of Fig. 3 180 decisions provide the TCTX 195 of transmission opportunity to Fig. 4, the CAM 180 of Fig. 3 just sends poll.con () primitive.The TCTX 195 structure PDU of Fig. 4 give PDU encoder it through data.req ().

Figure 10 describes retrieval and passes the data block process of sending out.This process is that the TCTX 195 by Fig. 4 carries out, each TCTX 195 structure CONTINUE PDU, the data block that has been sent out before it comprises but must have retransmitted again is because receiver can not be correctly to they decodings (that is the data backlog of another kind of type).The number of this data block depend on present modulator approach (as an example, 38 grades of modulation with 24 grades of modulation) and depend on before the End piece that sends whether must retransmit to notify receiver the relevant last ordinal number that should from transaction, expect.If this End piece must be retransmitted (End-RTx-Flag=False), this process produces this End piece and it is put into the SCCxT table 235 of Figure 12.If after the data block that retrieval is retransmitted, still have headspace in PDU, this process is just (underway as if terminal step with redundant End piece, promptly, End-Tx-Flag=True) or with filling block (, that is, End-Tx-Flag=False) fill this space if terminal step does not also begin.

Figure 11 illustrates the process of retrieving novel data block.This process is that the TCTX 195 by Fig. 4 carries out, each TCTX 195 structure CONTINUE PDU, the data block (the data backlog of any kind) that it never sent before comprising.The number of this data block depends on present modulator approach (as an example, 38 grades of modulation with 24 grades of modulation) and depend on whether the End piece sends with the relevant last ordinal number that should expect of notice receiver from transaction.If the former End piece that sends also must retransmit (End-RTx-Flag=False) again or if (NB-Tx＜NB-Max), then this process produces this End piece and it is put into the SCCxT table 235 of Figure 12 the number of the middle new data block of MAC buffer (TXB0 of Fig. 3 and TXB1) less than predetermined threshold value.If after the retrieving novel data block, in PDU, still have headspace, this process is just (underway as if terminal step with redundant End piece, promptly, End-Tx-Flag=True) or with filling block (, that is, End-Tx-Flag=False) fill this space if terminal step does not also begin.

Figure 12 describes structure PDU process 225, sends the used subchannel controller of (TxT) table 230 and Fig. 4 TCTX and sends (SCCxT) table 235.How various controls and data field fill with all values and data among the structure PDU process 225 explanation PDUs.The TxT table 230 of Figure 12 is the ARQ states that are used for tracing figure 4 transmit control devices 192, that is, in sending window before the data block state and the order of transmission.SCCxT table 235 is the relations that are used to follow the tracks of between piece and PDUs and the subchannel, has sent this PDUs on this subchannel.Whole MAC block messages in the relevant switching of SCCxT table 235 storage, they are also confirmed without physics control field (PCF).SCCxT table 235 also is used for helping structure PDUs.TxT table 230 and SCCxT table 235 all are the means of determining the data backlog of MAC layer.

Figure 13 represents the PCF process, as the part of 192 execution of mobile radio station transmit control device among Fig. 4.Ul transmissions had been received before PCF provided on the subchannel subchannel, just was updated corresponding to the transmission table that sends piece.The affirmation of all pieces that sent in the up link character group before on the AR of TC192 place.If PCF points out that the Q state variable also is updated with reflection PCF to be confirmed.For the piece of each affirmation, TC192 provides the data.con signal to sectionalizer (SGM0 of Fig. 3 or SGM1).If the data block that sent in the up link character group before on the subchannel is a negative acknowledgment through PCF, then this data block is labeled as and can retransmits.

The ARQ state procedure that the mobile radio station transmit control device of Figure 14 key diagram 4 is carried out.If the AMI and/or the pattern of mobile radio station suggestion are unacceptable, ARQ Status PDU can be used for distributing AMI and pattern to give this mobile radio station.Perhaps, it can point out that this mobile radio station must be waited for later AMI and/or mode assignments.This process also makes the ARQ state variable at TC 192 places and transmission table (TxT230 of Figure 12) upgrade.If the NND field among the ARQ Status PDU is set, then this mobile radio station hypothesis does not have new layer 3 data to send.If near the end of transaction, send the End piece, then in ARQ Status PDU, confirm this End piece by the EBR position.If ARQ Status PDU comprises status of a sovereign figure, point out the accepting state of all pieces in the receiver window, then this bitmap is used to upgrade reception and the resettability state (that is, transmit control device is understood this receiver window) that sends the Biao Neizhu piece.For each piece that bitmap is confirmed, TC 192 provides the data.con signal to sectionalizer.

The mobile radio station that Figure 15 is illustrated under the transaction startup receives the controller process.Reception controller (TCRX) 200 of Figure 15 key diagram 4 is from the PDU decoder of Fig. 3, PDEC0 or PDEC1, the signal that (at state Data.ind) obtains.The signal that Fig. 4 TCRX 200 that also draws sends, to the sectionalizer that goes of Fig. 3, DSGM0 or DSGM1, the process of (at state Data.ind) and MLC190 (at state StartRx.ind).

TCRX 200 at Fig. 4 is in idle condition, and BEGIN PDUs is received selectively.At the PDU decoder from Fig. 3, PDEC0 or PDEC1 receive after the BEGIN PDU, and whether TCRX 200 these transaction of decision of Fig. 4 confirm and whether this transaction is restricted (that is, being limited to the transfer of NB-Rx Data piece).For the ARQ transaction, TCRX 200 also determines the ARQ pattern (pattern 0 or pattern 1) of this transaction and initialization ARQ engine (also being referred to as the TC 192 of Fig. 4) under mode designated.The TCRX 200 of Fig. 3 provides the startup of MAC transaction with response BEGIN frame.

Mobile radio station received the controller process when Figure 16 illustrated in regular coding Mode A RQ transaction is carried out.Figure 16 represents from TCTX 195 (at state Poll.ind), the PDU decoder of the MLC190 of Fig. 3 (at state StopRx.Req) and Fig. 3, PDEC0 or PDEC1, the signal that (at state Data.ind) received by the TCRX 200 of Fig. 4.The TCRX 200 that Figure 16 goes back presentation graphs 4 delivers to TCTX 195 (state Data.req), and Fig. 3 removes sectionalizer, DSGM0 or DSGM1, the signal of the MLC 190 of (at state error.ind) and Fig. 3 (at state Error.ind).
