Description

The method and apparatus of terminal physical layer handling capacity limit negotiation

Technical field

The present invention relates to global inserting of microwave (WIMAX, World Interoperability for Microwave Access) wireless metropolitan area network technology, be particularly related to terminal physical layer in the WIMAX wireless MAN (PHY, Physical layer) capabilities limits negotiation method and device.

Background technology

IEEE 802.16E protocol definition insert (OFDMA based on OFDM, Orthogonal Frequency Division Multiple Access) mobile broadband wireless of physical layer inserts standard, adopt the WIMAX wireless metropolitan area network technology of this consensus standard to compare broadband wireless access technologys such as existing WI-FI, can reach higher throughput, service quality (QoS is provided, Quality of Service), the security performance and the better extensibility that strengthen, thereby this technology has obtained great concern in recent years, each big operator sets up experimental network and commercial network one after another in the world at present, and increasing communications equipment vendor also develops abundant WIMAX product.

Because the end product performance of different manufacturers produce has very big difference,, when giving certain terminal transmission business datum, just may influence business above terminal processing capacity if the different disposal ability of different terminals is not understood in the base station.Specifically, the part of most critical is exactly the size of the every frame deal with data of terminal up-downgoing amount in the terminal processing capacity, be also referred to as the up-downgoing limited processing ability, comprise media access control layer (MAC, Medium Access Control layer) limited processing ability and PHY limited processing ability two parts, if the base station can not satisfy the requirement of MAC and PHY limited processing ability for the business datum of terminal transmission simultaneously, terminal may cause loss of data even service disconnection because abandon the frame that the base station sends unusually.

For the MAC limited processing ability, agreement has defined special cell (IE, Information Element) holds consultation for terminal and base station, the cell of above-mentioned protocol specialized definition can be called the cell that the MAC limited processing ability is consulted, comprise at the 11.7.8.6.1 Maximum amount of MAC level data per DL frame of down link with at the 11.7.8.6.1 Maximum amount of MAC level data per UL frame of up link, defined a maximum number of byte and the maximum number of byte that the interior terminal of uplink frame can be handled that the interior terminal of downlink frame can be handled respectively, the two is a unit with 256 bytes all.

For the PHY limited processing ability, be not given for the cell that the PHY limited processing ability is consulted in the existing protocol, but in order between base station and terminal, also to hold consultation at the PHY limited processing ability, there is following solution at present, mainly comprise: in the process of base station and terminal interaction, after channel adjustment is finished, at terminal basic capacity (SBC, Subscriber Station Basic Capability) in the negotiation, the modulation coding mode that terminal to report self is supported, this reports by two defined cells and realizes in existing protocol, be 11.8.3.7.2 OFDMA SS demodulator and 11.8.3.7.2OFDMA SS modulator, stipulate according to agreement, whether these two cells can only the current terminal of informing base station support the modulation coding mode of 64QAM, at registration (REG, Registration) in the negotiation, by agreement is 11.7.8.6.1 Maximum amount of MAC level data per DL frame and the 11.7.8.6.1 Maximum amount of MAC level data per UL frame that the every frame capabilities limits of MAC is consulted definition, report PHY limited processing ability value to the base station, i.e. the maximum amount of data of handling to the every frame of base station reporting terminal.

Use said method, need preestablish several assumed conditions, comprising:

1) owing in SBC consults, reports the cell of definition of modulation coding mode, whether modulation coding mode that can only the current terminal of informing base station is 64 quadrature amplitude modulation (QAM, Quadratic Amplitude Modulation), will not notify for other modulation coding modes, if therefore the modulation coding mode of the current terminal of informing base station is not support 64QAM in SBC consults, the modulation coding mode that terminal is used can't be determined in the base station.In view of the situation, when supposing the current modulation coding mode of not supporting 64QAM of terminal, promptly acquiescence is supported the modulation coding mode of 16QAM.

When 2) supposing that terminal is supported certain modulation coding mode, terminal is supported all the FEC types in this modulation coding mode.For example, if terminal is supported the modulation coding mode of 64QAM, suppose that then terminal supports to comprise 1/2,2/3,5/6 FEC type in the 64QAM modulation coding mode, wherein 5/6 is called high order modulation coded system, the maximum that the every frame of counterpart terminal can the deal with data amount.

3) suppose that must there be strict derived relation in MAC limited processing ability (is unit with the byte) and PHY limited processing ability (is unit with slot).

Based on above-mentioned 1)-3) assumed condition, the explanation of above behavior example specifically comprises PHY limited processing ability negotiation method at present:

In terminal one side, clear and definite self the PHY limited processing ability value of terminal, for example 100 slot are handled in the up every frame restriction of the PHY on certain terminal, if the modulation coding mode of this terminal support is 64QAM, corresponding high order modulation coded system is 5/6, promptly a slot carrying byte number is 30, and then 3000 bytes are handled in the up every frame restriction of terminal PHY; In SBC consults, in the IE OFDMA SS modulator of SBC request (SBC-REQ) message, fill in " supporting 64QAM "; In REG consults, in the IE Maximum amount of MAC level data per UL frame of REG request (REG-REQ) message, fill in value 3000/256.

One side in the base station, the base station is according to the Maximum amount of MAC level data per UL frame and the OFDMA SS modulator of terminal to report, again in conjunction with above-mentioned assumed condition 2), think that promptly terminal supports all the FEC types in the 64QAM modulation coding mode, with high-order is the derivation benchmark, oppositely deriving the up limited processing ability value of terminal PHY is 100 slot of every frame, each slot carrying byte number is 30, when terminal sent business datum, the scheduling of every frame all must not surpass 100 slot follow-up.

At present the every frame capabilities limits of PHY is consulted the method for employing,, also has following defective though remedied the deficiency of agreement regulation to a certain extent:

Find in the actual test, for certain modulation coding mode, terminal may not supported all FEC types (the especially FEC type of high-order), for example in the 64QAM modulation coding mode, if terminal is not supported high order modulation coded system 5/6, and the base station is also still according to assumed condition 2) in the principle of defined oppositely derive, promptly support high order modulation coded system 5/6 oppositely to derive according to terminal, the result of result who draws like this and physical end PHY limited processing ability is inevitable inequality.

As seen, in consulting, SBC reports modulation coding mode according to the cell of stipulating in the present agreement, and the cell of consulting by the MAC limited processing ability in REG consults reports the method for PHY limited processing ability to the base station, may cause the negotiation of PHY limited processing ability the mistake that is difficult to avoid to occur, the base station according to negotiation result when the terminal transmit traffic data, still terminal be may cause because abandon the frame that receives unusually, thereby loss of data or service disconnection caused.

At first, introduce two kinds of methods that embodiment of the invention terminal PHY limited processing ability is consulted.

Fig. 1 is first kind of terminal PHY of embodiment of the invention limited processing ability negotiation method flow chart, and this flow process comprises:

Step 101: the cell that is used for the negotiation of PHY limited processing ability that the base station receiving terminal sends, the PHY limited processing ability value that carried terminal reports in the described cell.

In this step, the cell that the PHY limited processing ability is consulted is a cell newly-increased in existing protocol, can comprise that at the PHY capability Uplink frame of up link with at the PHY capability Downlink frame of down link these two cells are the PHY limited processing ability value that reports of carried terminal directly.PHY limited processing ability value in this step, can comprise the maximum amount of data that continuum size in the every frame of PHY and/or the every frame of PHY are handled, wherein the size of the continuum in the every frame of PHY is used than the littler unit of slot as data unit, and the maximum amount of data that the every frame of PHY is handled both can use slot as data unit, also can use than the littler unit of slot as data unit, for example, if slot multiply by a sub-channel metrics with three symbols in uplink frame in existing protocol, and in downlink frame, multiply by a sub-channel metrics with two symbols, the then above-mentioned unit littler than slot can adopt a symbol to multiply by a sub-channel metrics at uplink/downlink frames.

Step 102: the PHY limited processing ability value of described terminal to report, negotiation terminal PHY limited processing ability are used in the base station.

In this step, the negotiation that carry out the base station can have different execution modes based on different situations.When there was not the PHY limited processing ability in base station itself, the PHY limited processing ability value of terminal to report can directly be duplicated as the result who consults in the base station; When there was the PHY limited processing ability in base station itself, the PHY limited processing ability value of base station comparison self PHY limited processing ability value and terminal to report was got minimum value as the result who consults.

The cell that is used for the negotiation of PHY limited processing ability in the above-mentioned steps 101 can send to the base station by terminal by the SBC request message, and can further include after the negotiation terminal PHY limited processing ability in the step 102 negotiation result is returned terminal, can this negotiation result be returned terminal by the base station by the SBC response message.

First kind of terminal PHY of embodiment of the invention limited processing ability negotiation method, terminal sends to the base station and is used for the cell that the PHY limited processing ability is consulted, the PHY limited processing ability value that carried terminal reports in this cell, for terminal directly reports PHY limited processing ability value that approach is provided to the base station, the base station can use the PHY limited processing ability value of these terminal to report directly to hold consultation, and accurately draws the negotiation result of PHY limited processing ability.

Be example with concrete application scenarios below, introduce several better embodiment of first kind of terminal PHY of embodiment of the invention limited processing ability negotiation method.

The better embodiment one of first method

Suppose that the application scenarios in this better embodiment is: the terminal initial access network; The PHY limited processing ability value that terminal reports to the base station comprises the size in continuous data zone in data maximum that the every frame of the PHY of terminal is handled and the every frame, wherein the data maximum of the every frame processing of PHY is data unit with slot, and in every frame the size in continuous data zone with than the littler unit of slot as data unit, for example a symbol multiply by a subchannel and measures this unit littler than slot; There is not the PHY limited processing ability in base station itself; The PHY limited processing ability consults to finish in the SBC negotiations process, and wherein terminal reports PHY limited processing ability information by SBC-REQ, and the base station is returned negotiation result by SBC response message (SBC-RSP) to terminal.

In this better embodiment, the cell that is used for the negotiation of PHY limited processing ability that increases newly is positioned at existing protocol 11.8.3.7 OFDMA PHY parameter chapters and sections, table one and table two show the structure of this PHY limited processing ability negotiation at descending and up cell respectively, and this structure just illustrates.

Table one PHY capability per Downlink frame

Table two PHY capability per Uplink frame

Fig. 2 shows the flow chart of this better embodiment, and this flow process comprises:

Step 201: carry cell PHY capability per Downlink frame and PHY capability per Uplink frame in SBC-REQ message, the size of continuum reports the base station in the data maximum that the every frame of terminal PHY is handled and the every frame.

Step 202: there is not the PHY limited processing ability in base station self, and the PHY limited processing ability value of duplicating terminal to report is as negotiation result.

Step 203: the base station sends SBC-RSP message to terminal, the negotiation result of carrying in the step 202 in this message to be drawn, still send by PHY capability per Downlink frame and PHY capability per Uplink frame, this result shows that the base station accepted the PHY limited processing ability situation of terminal.

Above-mentioned steps 201～step 203 is descriptions that negotiations process is carried out at the PHY limited processing ability, the conventional steps that before step 201 and after the step 203, also comprises base station and terminal interaction, these steps all are those skilled in the art's common practise, repeat no more here.

After the above-mentioned steps 203, and after follow-up business stream is set up and is finished, base station and terminal communicate, to each uplink frame and downlink frame structure MAP (MAP, Mobile Application Part) during message, the base station all can be dispatched according to the result that the PHY limited processing ability is consulted, and guarantees to be transferred to the business datum of terminal within terminal PHY limited processing ability.

The better embodiment two of first method

Suppose that the application scenarios in this better embodiment is: the terminal initial access network; The PHY limited processing ability information that terminal reports to the base station comprises the data maximum that the every frame of the PHY of terminal is handled, and this data maximum is data unit with slot; There is the PHY limited processing ability in base station itself, is the data maximum that PHY every frame in base station is handled, and this data maximum also is data unit with slot; The PHY limited processing ability consults to finish in the SBC negotiations process, and wherein terminal is by SBC-REQ information reporting PHY limited processing ability value, and the base station is returned negotiation result by SBC-RSP message to terminal.

In this better embodiment, the cell that the PHY limited processing ability that increases newly is consulted, be arranged in existing protocol 11.8.3.7 OFDMA physical layer parameter chapters and sections, the structure of this cell and table one are with similar shown in the table two, but because the maximum amount of data that the every frame of PHY is handled is only paid close attention in PHY limited processing ability aspect, therefore only fill in maximum slot number in the 0-7 bit, other bits can adopt the mode such as 0 of putting.

Fig. 3 shows the flow process of this better embodiment, and this flow process comprises:

Step 301: carry cell PHY capability per Downlink frame and PHY capability per Uplink frame in SBC-REQ message, the data maximum that the every frame of terminal PHY is handled reports the base station.

Step 302: there is the PHY limited processing ability in base station self, and the data maximum that the data maximum that the every frame of PHY of base station comparison self is handled and the every frame of PHY of terminal to report are handled is got the result that minimum value is consulted as the PHY limited processing ability.

Step 303: the base station sends SBC-RSP message to terminal, carries the minimum value that compares gained in the step 302 in this message, promptly carries the negotiation result of PHY limited processing ability.

Similarly, after follow-up business stream after the above-mentioned steps 303 is set up and is finished, base station and terminal communicate, during to each uplink frame and downlink frame structure MAP message, the base station all can be dispatched according to the result that the PHY limited processing ability is consulted, and guarantees to be transferred to the business datum of terminal within the PHY limited processing ability.

If in this better embodiment, terminal is also restricted to the size of continuum in the every frame of PHY, and the base station is also restricted in this respect, and then in step 302, also can hold consultation according to the method for the comparison of being introduced in this respect in the base station.

In the better embodiment one and better embodiment two of above-mentioned first method, describe all be the terminal initial access network time how to hold consultation at the PHY limited processing ability with the base station, in actual applications, terminal is after initial access network, also may switch and reenter network or re-accessing network under idle pulley, being terminal switches to the process of other base stations from current serving BS, and the base station that can switch to is called target BS.

Wherein when terminal is switched re-accessing network, terminal is optimized situation according to re-accessing network may not have SBC-REQ message, target BS can obtain the PHY limited processing ability value of terminal to report and the PHY limited processing ability negotiation result of terminal from current serving BS, if self there is the PHY limited processing ability in this target BS, can use the PHY limited processing ability of self to hold consultation again with the PHY limited processing ability value of the terminal to report that obtains, if new negotiation result is different with the PHY limited processing ability negotiation result of the terminal of obtaining, then target BS can send to terminal by RNG-RSP message or independent SBC-RSP message with new negotiation result, in the service dispatching after the terminal re-accessing network, target BS according to new negotiation result to the terminal transmission business datum.

When terminal under idle pulley during re-accessing network, processing mode during with above-mentioned switching re-accessing network is similar, just the serving BS of terminal needs earlier the PHY limited processing ability value of terminal to report and the PHY limited processing ability negotiation result of terminal to be sent to paging controller, and target BS obtains the PHY limited processing ability value of terminal to report and the PHY limited processing ability negotiation result of terminal from above-mentioned paging controller.

In the better embodiment one and better embodiment two of above-mentioned first method, being used for cell that the PHY disposal ability consults SBC request message and the SBC response message by the SBC negotiation phase carries, this is a kind of preferred implementation, can also carry this cell in the request message of RNG negotiation phase or REG negotiation phase or response message.

Fig. 4 is second kind of terminal PHY of embodiment of the invention limited processing ability negotiation method flow chart, and this flow process comprises:

Step 401: the cell that is used for the modulation coding mode negotiation that the base station receiving terminal sends, the modulation coding information of carried terminal in the described cell.

Step 402: the modulation coding information of described terminal is used in the base station, and the high order modulation coded system that negotiation terminal is supported is returned the high order modulation coded system of described terminal support to terminal.

Step 403: the maximum amount of data that every frame that the cell that the base station receiving terminal is consulted by the MAC limited processing ability reports is handled.

Step 404: the base station is according to the high order modulation coded system of described terminal, from the cell that described MAC limited processing ability is consulted, parse the maximum amount of data of every frame processing of terminal, with the maximum amount of data of the described every frame processing that parses, as the negotiation result of terminal PHY limited processing ability.

In this step, the base station parses the method for the maximum amount of data that the every frame of terminal handles, be the high order modulation coded system of supporting according to the terminal of consulting, consult the content that cell carries, oppositely derive the maximum amount of data that the every frame of terminal PHY is handled from the MAC limited processing ability.

Second kind of terminal PHY of embodiment of the invention limited processing ability negotiation method, by terminal by being used for the cell that modulation coding mode is consulted, directly provide modulation coding mode information to the base station, the base station modulation coding information that can provide according to terminal then, the high order modulation coded system that negotiation terminal is supported, thereby improve accuracy during the maximum amount of data that every frame of resolving terminal to report the cell of consulting from the MAC limited processing ability is handled, make terminal and base station can accurately consult the PHY limited processing ability.

In the second method that the embodiment of the invention provides, the modulation coding information of terminal to report comprises two kinds of situations: modulation coding mode tabulation of self supporting and the high order modulation coded system of self supporting.At above-mentioned two kinds of different situations, the base station is when the high order modulation coded system that negotiation terminal is supported, the operation of being carried out is also inequality.

When terminal by the cell that is used for modulation coding mode and consults report be the modulation coding mode tabulation of self supporting the time, the modulation coding mode in the described modulation coding mode tabulation is used in the base station, the high order modulation coded system of supporting with self relatively, all modulation coding modes of the high order modulation coded system of selecting that exponent number is supported smaller or equal to self in the tabulation of described modulation coding mode, again from the described modulation coding mode of selecting, the negotiation result of the high order modulation coded system of supporting as terminal that exponent number wherein is the highest, the base station is used for the cell of modulation coding mode negotiation when terminal is returned negotiation result, what carry in this cell also is list information, high order modulation coded message in this list information is exactly the high order modulation coded system that the terminal that negotiates is supported, terminal receives the modulation coding mode of knowing the high-order of wherein consulting behind this list information.

When terminal by the cell that is used for modulation coding mode and consults report be the high order modulation coded system of self supporting the time, the high order modulation coded system of described terminal to report is used in the base station, the high order modulation coded system of supporting with self relatively, select the negotiation result of the high order modulation coded system that modulation coding mode that wherein exponent number is little supports as terminal, the base station is used for cell that modulation coding mode consults when terminal is returned negotiation result, and what carry in this cell is exactly the high order modulation coded system of the terminal support consulted.

In two kinds of situations that the modulation coding information of above-mentioned terminal to report comprises, be used for the content difference that cell that modulation coding mode consults carries, the list information that promptly carries is different with the high order modulation coded system that directly reports, and therefore is used for the cell that modulation coding mode consults and will has different structures in above-mentioned two kinds of situations.

Below in conjunction with concrete application scenarios, a kind of better embodiment of second kind of terminal PHY of embodiment of the invention limited processing ability negotiation method is described.
