Abstract

Position based WPAN (wireless personal area network) management. Based on either the relative position or the specific location of devices within a WPAN, communication between the various devices is managed by grouping the devices into two or more groups. In addition, the communication between theses various devices may be governed by profiles assigned to the groups (or even the actual individual devices) that are assigned based on their locations within the WPAN. The relative locations of the devices may be made using ranging that is performed by transmitting UWB (ultra wide band) pulses between the various devices within the WPAN. Alternatively, each device may include GPS (global positioning system) functionality and information corresponding to the specific locations of the devices may be communicated between the devices, and that information may be used to group devices user and/or assign profiles to govern the communication to and from the devices.

Description

1261435 IX. Description of the invention: [Technical field to which the invention pertains] ‘In particular, the invention relates to communication management of a communication system in the communication system. [Prior Art] The bedding communication system has been continuously developed for many years. In recent years, piconet-type communication systems have grown faster. A piconet can be seen as a network that is established when two devices are connected to support poor communication between them. Sometimes, piconet is also known as pAN (personal area network). The piconet typically operates in an area having a radius of up to about 10 meters. As we all know, the Bluetooth communication standard is the first PAN communication standard that has been developed so far. In a piconet, the communication between different devices works in strict accordance with the M/S (master/slave) configuration. In a Bluetooth piconet, each device in the device can be configured in a master/slave configuration. In general, one of these devices (in this case, sometimes referred to as a piconet controller) or the first device of the Bluetooth piconet acts as the "master" device of the Bluetooth piconet to the Bluetooth piconet. From, the device transmits beacon communication (or accesses the invitation communication). In other words, the main I of the Bluetooth piconet polls the slave device and requests it to respond. However, other piconets can be implemented so that the devices do not follow this Μ/S (master/slave) relationship work. In this case, devices that can run different piconets can be called PNC (piconet coordinator) and DEV (pseudo network device for non-PNC users). Communication between DEV and its own within the piconet. Sometimes, 1261435 = 3 riding one or more as the main running coffee as the main 'I' but riding the tree to strengthen this, generally only Bluetooth micro Strict Μ/s relationship. There are some other situations in the track. 'Two or a plurality of piconets cooperate to operate, and at least two micro-networks operate to make the distribution network (distributed network) realize 2 less one correction device For example, in the case of distribution, DEV can be combined with two or A number of PNC fathers. This kind of Wei can make different devices in different piconets that are far apart from each other communicate through the PNC of the distribution network. However, in the distribution network implementation, the monthly b can appear - the problem · each pico Each of the nets must be close to each other without interfering with each other. It is required to perform a large number of synchronizations in the local area. 'It is difficult to achieve in some cases. It should also be noted that it is not realized in the distribution network. The piconet that works independently may also be adversely affected by other piconet interferences that work relatively close. The IEEE (Electrical and Electronics Engineers Association) Working Group 8〇215 has developed pAN communication standards and recommended practices (some These standards and draft recommendations are generally provided under the protection of the IEEE 8〇215 Working Group. Perhaps the most common standard is the IEEE 8〇2151 standard, which uses the dental core' and its general support. Up to approximately 1 Mbps (million bits per second) operating rate. The proposed IEEE 802.15.2 draft specification is intended to support the IEEE 802.15.1 dental core and possibly any other wireless communication. The system coexists in the frequency range of about 1261435 2.4 GHz. As an example, the Qiqiu, 8〇2.lla and IEEE 8〇2.llg wlAM (Wireless Local Area Network) standards all work at about 2.4. Within the scope of GHz, this (10)2"5.2 draft proposal has been developed to ensure that WLANs and piconets can work in close proximity to each other while not significantly disturbing each other. Another 'developed ΙΕΕΕ8〇2·15·3 high data rate pAN standard, trying to support the I rate of about 55Mbps in South. In the right j ffiEE 8 () 215 3 standard ^, PNC and DEV do not work in accordance with the relationship between the two according to Bluetooth. In contrast, PNCs generally work as APs (access points) and manage their differences to ensure that their respective communications are completed in accordance with their appropriate time slots, thus ensuring proper performance and difficulty in the piconet. (10) 2"5·3 Gaolong rate pAN standard extension is IEEE 802.15.3 WPAN (Wireless Personal Area Network) high data rate replacement PHY task group Zumba). It is sometimes referred to as the extension of the high data rate PAN, which supports operating rates up to 48_ps. The standard system developed by the 1EEE 802.15 working group is the 资料8〇2·ΐ5·4 φ low data rate ΡΑΝ standard, which generally supports data rates in the range of approximately 1 〇 kbps (kilobits per second) and 250 kbps. Generally, in such a WPAN, the communication between each user equipment and a pNc (pseudo-network) (and between peer-to-peer (p2p) different user devices) is based on, for example, a single code rate, a single modulation, and a single domain data. The rate is equal to the general scheme. There is currently no such device in the prior art, so that communication between different devices traveling to and from a 1261435 or multiple piconets can be handled by any other method than the conventional solution. SUMMARY OF THE INVENTION The different features of the present invention can be found in WPAN (Wireless Personal Area Network). The WPAN includes a PNC (Pico Network Coordinator) and a plurality of DEVs (User Pico Net Devices). The PNC transmits a UWB (Ultra Wide Band) pulse to each of the plurality of DEVs. After receiving their respective UWB pulses, each of the plurality of devs sends back a UWB pulse to the PNC. The PNC determines the relative distance of each of the PN and the plurality of DEVs by performing a distance correction of the relative position of each of the plurality of DEVs by the length of the round trip time of the transmitted UWB pulse and the received UWB pulse. Then, based on the distance correction of each of the plurality of DEVs, the PNC divides the plurality of DEVs into at least two groups' and determines a corresponding round for the parent group. Each set of profiles manages communication between the DEV and PNC of the group (and can also manage communication between the groups of DEVs). In some embodiments, the WPAN includes two different piconets (e.g., a first piconet and a second piconet) supported by two different PNCs. In such an embodiment, both PNCs complete the distance correction for all DEVs within the WPAN. Then, the two PNCs cooperate to divide each DEV into groups that can be served by each PNC by distance correction information. In some other embodiments, the PNC establishes p2p (peer-to-peer) communication between the two DEVs. The PNC identifies the corresponding p2p profile to manage the communication between the two DEVs communicating via the p2p communication 1261435 mode. The p2p profile includes data rate, buffer density, code with code rate, and TFC (time frequency code). The PNC can be used as a repeater for P2P communication between DEVs. It should also be noted that any one of the contours can include: #料率, modulation density, code with code rate, and any or a plurality of TFCs. . ^ The group divided by the DEV can be divided into at least two groups such that one set of devices is closer to the PNC than to the other set. The first group employs a first profile, with a first data rate, a first modulation density, a first code having a first code rate, and at least a second of the second ones - managing the communication between the DEV and the café. The second group employs a second profile, a second dragon rate, a second tone (four degrees), a second code having a second code rate, and at least one of the second TFCs - managing the second group and the PNC. In some cases, the first-five rate is the second dragon rate. Alternatively, the modulation density may be on the order of magnitude higher than the second modulation density. In addition, the first code rate is higher than the second code rate. Can be separated by the mother __ complete - money a number of DEV in each - Qing distance correction.

[Embodiment] The first figure A is a UWB (super 24 1261435 embodiment) compared with some other types of signals of the present invention. The energy pulse is transmitted on the spectrum by a narrowband frequency carrier transmission; ^Τ: 'Γ communication By the whole width _ ordering work, such as 'financial number can be regarded as occupying a narrow frequency' such as 15. In addition, its power transfer density (PSD) - generally rises ^ frequency of ~ other interference signals within the PSD, Moreover, the spread spectrum signal that occupies a relatively narrow portion of the available spectrum is completely different. The WB signal can actually be regarded as a pulse-signal (the pSD is more than the PSD of other ^-disturbing signals in the spectrum). Her __ signal needs to take the band of small bandwidth bribes. For example, the amount of Wei machine domain (that is, originally concentrated on narrowband) is spread over a wider frequency band. One of the advantages of spread spectrum signal 102 is that it has narrowband interference. Provide immunity. Casting 101 can't erase UWB -5fU Tiger 1〇3 'Because UWB signal 1〇3 has much wider bandwidth. Note that ^103 signal 103 has the same function as a function of time, not a frequency function. Figure B is a diagram of the present invention dividing the spectrum of UWB (Ultra Wide Band) into sub-frequencies One embodiment of the band. Relatively speaking, the FCC (Federal Communications Commission) has recently defined the spectrum available for UWB communication between 3.iGHz (gigahertz) and 10.6GHz. In addition, the FCC will also be available in any UWB in the UWB spectrum. The minimum spectral width of the signal is defined as 500 MHz (megahertz). In addition, the definition of the FCC allows the PSD of the UWB spectrum spanning the bandwidth of 41.25 dBm/MHz. As a cue signal, the OdBm reference is the signal power decibel of imw (milliwatts) ( dB), which means that the total power available to UWB is approximately -14.26 dBm over any single 5 〇〇 MHz sub-band over the UWB bandwidth over 7.5 GHz. Alternatively, if the pulse is available in UWB bandwidth For the entire 7.5 GHz transmission, the total transmission power of the UWB is about _2 5 dBm. Figure 2A is an embodiment of a piconet (denoted as a wireless personal area network) constructed by the present invention. As described above, the piconet can be viewed. A network established by any two devices connected to communicate with each other. The piconet can be implemented by a PNC (Pico Network Coordinator) 201 and one or a plurality of DEV202_210 (piconet devices). In some cases, DEV don't directly interact with each other Communication, but through the PNC to communicate with each other. In order to support the communication between each DEV and PNC 201 at some time, the communication must be realized in one way, that is, the communication key between each DEV and pNC2〇2 will not Interfering with other communication links in any other SOP (simultaneously operating piconet) that are relatively close in range. That is, when two or more piconets are operating relatively close to each other, each of the respective piconets Communication must be achieved in such a way that two or more piconets can operate simultaneously (ie coexistence and operation) without interfering with each other. It should also be noted that PNC2 (n operates to enable p2p (peer-to-peer) communication between two DEVs within a piconet. Further, the piconet operation in this embodiment and other embodiments described herein follows IEEE 802.15. The constraints provided by the 3a standard, and may also be implemented such that the piconet runtime also follows other wireless standards. Figure 2B is an example of a TFC (time frequency code) 26 126 435 κ ̄ e. Function, the frequency band being used will jump from one frequency band to another. The use of TFC is an operational measure to make the communication channel more robust. For example, when noise such as background noise is relatively limited to the spectrum, a specific port P knife $ TFC will help minimize the harmful effects of this particular frequency-limited noise. 1 Frequency hopping can be seen as a period of time (four) in the frequency of the firing process. In a pass (10), the transmitter and receiver operate synchronously, making Any given time = every one runs at the same frequency. In this particular embodiment, the available spectrum is divided into n frequency bands. In the first time interval communication is operated by frequency band 1, In the first: time interval, the band η works, and the third time interval is operated by the band 3' and continues to work as shown in the schematic diagram. It should also be as long as the _ _ _ interval is long enough _ The whole pulse of the communication channel is _. The time interval of the communication at any given frequency is generally reduced by the length of the symbol. ___ - Example 'in the case of the signal, it is difficult Γ is divided into 15 sub-bands with a bandwidth of 5_Z. The frequency hopping can be seen as a function of hopping between different sub-bands with a bandwidth of 5G() MHz. The third picture is compared with the impulse response of the communication channel. FC (time = one of the side hopping time intervals. For the communication between the two and the daily sales = NC and -), the impulse response is taken as ^ and the pulse response can be regarded as a communication secret. Pulse 27 1261435 The sword as a time letter in intensity can be seen as a response to the communication system of the communication channel 205. The pulse changes in response to the number of attenuations. The pulse responds to the pulse response time of the time required for complete attenuation.

-===The pulse handsome (four) is called communication _ by the first (meaning the first day - the frequency band in the interval υ tfc time interval of the duration of the performance than the communication channel pulse response time is much longer. In some embodiments, the duration of the TFC interval is considerably longer than the pulse response time of the pass channel. As an example, the interval length can be as much as 1 G times the communication channel pulse period (eg, ·). It allows all the energy of the pulse to be generated at the time of transmission and on the (four). Similarly, when switching according to TFC to another, the phaseliner will also respond longer than the communication channel pulse. In the technology of the piconet method, frequency hopping has been implemented, that is, the time interval is generally only one symbol long; it is generally much shorter than the impulse response time of the communication channel. As the case, if the frequency hopping is completed too fast, the pulse is transmitted. Most of the energy will be lost. In accordance with the present invention, the frequency hopping is completed over a longer period of time to capture the full energy of the transmitted pulses, thereby ensuring more robust and more accurate communication. Further, the present invention provides a solution. Will OF The DM coding and the TFC modulation of the OFDM symbols are combined to support the simultaneous operation of a plurality of piconets, each of the plurality of piconets including a plurality of DEVs.

It should be noted again that the PNC enables P2P 28 1261435 (peer-to-peer) communication for two separate DEVs within the piconet. The communication method described herein can be realized by communication between pNc and the piconet DEV, and can also be realized by p2p communication between two separate networks in the piconet. The fourth figure is another embodiment of a TFC (Time Frequency Code) that can be employed in accordance with the present invention. This embodiment shows that the two separate piconets work by dividing the TFC by two orthogonal to each other. However, it should also be noted that the number of TFCs used to support s〇p (simultaneously running piconet) communication continues to increase, and considering the limited number of bands used in any tfc, the orthogonality of the test_holding TFC The more difficult it is. Although it is possible to achieve when the number of SOPs is small, as the number of s〇p increases, it becomes impossible to take into account the inherent periodicity of the TFC. However, in the embodiment where only two SOPs are used, the piconet i uses TFC" to support the communication between the I stations included therein. In addition, the piconet 2 uses 2 to support communication between the devices included therein. In the present embodiment, each of the 'TFC 1 and TFC 2' in each of the intervals is operated by a different frequency band. For example, when D1 FC1 is frequency dependent, Dc Fc 2 operates by Band 2. Similarly, when TFC 1 operates by Band 2, TFC 2 operates by Band 5. The two-but Fc orthogonal operation continues during the respective SOP work. Each of the respective TFCs repeatedly supports each subsequent work in the respective piconet. This orthogonal operation of the two TFCs allows more than one piconet to coexist in relatively close proximity to each other. In addition, it should be noted that each device in the respective piconet communicates with each other by corresponding to the piconet iTFC. 29 435 弟一弟五图健吻日__之晴 (code is divided into Wei. CDMA can be regarded as a short-term allocation to Ke Qian " = continuous time slot, the band allocation is non-adaptive, that is, according to the predetermined turn Performing work by Band 2 and Signal 3 by frequency work'

The body signal 1 is called by the frequency band 3, the signal 2 is made by the frequency band U, and the signal 3 is hunted by the frequency f 2 guard. During time slot 3, the signal is operated by the band, the signal 2 is operated by the band 2, and the job 3 is operated by the band 3. * The work of screaming (such as the user) is done by the pN (pseudo-dummy) code and the other PN code-like and communication 丨_ The hash code is often referred to as spread spectrum coding. The modulation signal is extended by the spread spectrum coding. At the receiver end of the face channel, the same spread spectrum coding (i.e., the weight) is used to despread the signal to enable the data transmitted from the particular device to be demodulated by the appropriate target device. Considering CDMA as the input signal is transformed by the communication system, the work of CDMA can be better understood. At the transmitter end of the communication channel, the input of a particular user is first provided to the modulator 5〇1, where the data is modulated by the carrier to produce a modulated signal (si) 5〇2. Then, the data modulated signal 5 〇 2 is multiplied by a spread spectrum code (gl ) 504 corresponding to the particular user to generate a spread spectrum signal (glsl), which is then supplied to the communication channel 503. This signal can be regarded as a convolution of the modulated signal spectrum and the spread spectrum encoded spectrum. At the same time, the input 506 of another user within communication system 30 1261435 is modulated and spread in a similar manner. At the receiver end of the communication channel, it receives a linear combination of all the spread signals provided by other users, such as glsl+g2s2+g3s3+··· until all users. Then at the receiver, the total received signal is multiplied by the spread spectrum code gl5 〇 8 to produce a synthesis including gl2sl 吼唬 plus unwanted signals (eg glg2s2+glg3s3+···, etc.). In CDMA, spread spectrum coding is generally chosen to be orthogonal to each other. That is, when any-spread code is compared with other spread code, the result is 〇. Given the spread spectrum coding gl(t), g2W, g3(t), etc., the orthogonality of the spread spectrum coding can be expressed as follows: a fgi(1)gj(t)dt 〇

Then, after the fine Wei Wei is transferred to H, the signal provided by the transmitter of the orbital channel is extracted here and optimally estimated. The sixth figure is an embodiment of the 0FDM (Positive Domain Division Multiple Access) according to the present invention. 0 ugly coding can be seen as dividing the available spectrum into a plurality of narrow-band subcarriers (such as carriers with lower data rates). In general, the frequency response of these subcarriers is overlapping and orthogonal. The per-subcarrier can be transmitted simultaneously by the narrowband carrier of the multi-reproduction coding technique. The guard time interval and the OFDM coding are performed by performing a larger number. There is often a 12,614,35 space gap between different OFDM symbols in an attempt to reduce the lsi (symbol interference between symbols) caused by the multipath effect in the communication system (especially in the wireless communication (4)). The smallest. In addition, in the guard interval, _ cp (CydicpreflX) can also be used to counter the singular effect of the channel used for the purple data transmission. In general, CP can be seen as a more effective ageing. In one embodiment, 125 base frequencies can be implemented to generate a signal in the subband of 15 bandwidths 5 Ζ in the area spectrum. Hunting by OFDM encoding can also yield other benefits. For example, multiple fundamental frequencies can provide an effective method to handle the interference. One of the fundamental frequencies corresponding to the position of the scale can be turned off (to eliminate the sensitivity to the narrowband interference), but it can still operate effectively. This method of turning off one or more fundamental frequencies does not cause significant bandwidth loss' because the bandwidth available for each of the individual fundamental frequencies in the 0FDM symbols does not occupy a large bandwidth. Therefore, 〇FDM coding provides a solution that combines the 〇F brain coding with the TFC modulation of the present invention to compensate for narrowband interference without sacrificing a large amount of bandwidth. The seventh figure is an embodiment of a location-based intra-piconet management (represented by a radial embodiment) in accordance with the present invention. This implementation shows how the relative distance between different (user piconet devices) and PNC (piconet coordinator) can be used to divide the DEV into at least two groups (e.g., more than one group). In this embodiment, it is determined that the strict path issued as the position from the PNC is performed. In the area 每, each DEV has a reachable portion (more frequently, a portion that can support no 1261435 line communication), these DEVs Equally divided into Group 1. In this embodiment, DEV is DEV 1 202 and DEV 4 208. Communication between DEV 1 202 and DEV 4 208 is managed as Profile 1. As described in more detail below, there are several possible parameters. Included in the profile. Some possible parameters include code rate, modulation density, data rate, and/or TFC. However, other parameters may be included without departing from the scope and spirit of the present invention. The grouping, DEV 2 204 is divided into area 2. The communication between DEV 2 2〇4 and PNC 2〇1 is managed according to profile 2. Continuing to explain the grouping of DEVs in this embodiment, DEV 3 206 is divided into area 3. DEV 3 The communication between 206 and PNC 201 is managed according to profile 2. Continuing with the description of the grouping of DEVs in this embodiment, DEV 5 210 and DEV6 212 can be grouped into areas 3 beyond the area. DEV 5 210 and DEV6 212 and PNC 201 Communication between the four according to the corridor Each of the different profiles of the communication between the management PNC and the different sets of DEVs includes a number of signatures and any other parameters selected by the particular designer for the location-based WpAN management system. The number of parameters includes data rate, modulation density. The code with the code rate and the TFC. In addition, the contour selected from the _ group of possible contours or the same contour can also be used to manage the p2p communication between the communication systems. As shown in the real towel, the DEV is divided. In the circle (in two dimensions) or in the larger and larger ball, the p 12c is issued by the distance of 33 1261435 (in three dimensions). To determine the relative distance between SPNC and DEV, PNC Each DEV transmits a UWB (Ultra Wide Band) pulse. After each corresponding DEV receives its own UWB pulse, the DEV sends back another UWB pulse to the PNC. The pNC transmits the UWB pulse and the received UWB pulse. The round trip time length is corrected for the distance of each DEV relative position to determine the relative distance between the PNC and each DEV. This is by means of a relatively short duration of UWB pulses (eg, the length is generally less than lmec (nanoseconds) Therefore, the UWB pulse generally travels at a speed of about insec/feet. It allows the PNC to resolve the signal to within about lnsec, thereby relatively accurately measuring the relative position of the DEV to the PNC. And the completion of the distance correction, which is mainly done by the PNC, it should also be noted that any one or a plurality of DEVs can also be implemented to complete the distance correction. The distance correction method performed by the DEV can be used to request a profile and/or assign the particular DEV to a group, the group of communications being managed according to a profile.

Other embodiments may use alternatives such as GPS (Global Positioning System) functionality included in different devices and/or two-dimensional calculations including at least three devices (e.g., a PNC and two DEVs) to determine location information for different device towels. This alternative embodiment will be mentioned below and will be described in detail. The eighth figure is an embodiment of a position-based microgrid management (represented by a radial embodiment) in accordance with the present invention. This embodiment shows that there are a number of 34 1261435 DEVs and two PNC4NC 1 201 and PNC 2 203 that can work to complete the distance correction of all DEVs in the area. PNC 201 & PNC 2 203 collectively completes the distance correction of all DEVs, grouping them accordingly, and selecting the communication wheel for managing the communication between the DEV and PNC 1 201 and PNC 2 203. In addition, one or both of the PNC 1 201 and the PNC 2 203 can guide two or more DEVs to perform p2p communication therebetween, and complete the distance correction between the relative distances, and then

This information is provided to PNC 1 201 and PNC 2 203. At the same time, the triangle calculation can be done by one or both of PNC 1 201 and PNC 2 203 to determine one or a plurality of precise positions of the DEV in the region relative to PNC 1 201 and PNC 2 203. In the present embodiment, the distribution of the DEV is the same as that of the embodiment described above, except that there are two PNCs in this embodiment. Therefore, the grouping of DEVs can be done in different ways, while at the same time providing a more efficient implementation. For example, those DEVs that are close to the PNC 2 203 can be grouped together; the DEV 2 204, DEV 3 206, and DEV 6 212 can be divided into a piconet (such as the piconet 2) for communication according to the management area of the corridor 3. PNC 1 201 serves the remaining DEVs 1 202 and 4 208 (in area 1 by rim!), while TMC 1201 serves DEV 5 210 (outside area 3 of outline 2). These DEVs and PNC 1 201 can be viewed as another piconet (e.g., piconet 1). It can be seen that the contour becomes more robust as the DEV group moves away from the respective PNCs to become 35 1261435. For example, as the communication link becomes more noisy, a lower data rate, a lower density density, or a more robust code can be used to manage the DEVs that travel away from the appropriate PNC. This principle of increasing the stability of the wheel as it moves away from the coffee can also be applied to other realities. In addition, the Gu can also select the appropriate wheel to manage the communication between the two DEVs in the P2P communication system. When the two DEVs are relatively close to each other, a less robust profile (e.g., a higher data rate and/or a higher modulation density) may be used as the two DEVs are relatively close to each other. The ninth figure is an example of a piconet-based (indicated by a triangle) based on location within the ship's bribe. This embodiment shows how the distance correction is performed by P2p communication between different DEVs and the three-dimensional calculation using pNC 2〇1 and each completed lining correction. Knowing the relative distance between different DEvs, it is known that the relative position of each other can be determined with high accuracy. For example, the P2P distance correction between DEV 1 202 and DEV 2 204 and the distance correction information between PNC 201 and DEV 1 202 and DEV 2 204 can be used to determine the specific location of the device within the area. The pNC 2〇1 can perform the distance correction between the dev 202 and the DEV 2 204 by itself, and the PNC 2〇1 can guide the DEV丨2〇2 and one or both of the DEV 2 204 to complete the p2p distance correction therebetween. Then, one or both of the DEV 1 202 and the DEV 2 204 can send the distance correction 5f back to the PNC 201, so that the PNC can perform a triangulation calculation to determine the specific positions of the three DEVs with each other. In this way, more precise grouping can be performed. Or, it can be selected for each DEV served by its own PNC 2〇1 36 1261435

Choose the appropriate outline. Similarly, trigonometric calculations can be accomplished by PNC 2〇1 and ;dev 2 202 and DEV 3 206. Alternatively, each device may include a GPS function that can discriminate the absolute position of the device on the earth from the particular accuracy provided by the Gps#. This information can be transmitted between different I sets, enabling them to be properly grouped and contoured to manage communications to and from these devices. In recent years, Gps technology has matured and it is possible to include this positioning function in different devices without significantly increasing its complexity. In any of the embodiments of distance correction, triangulation, or GPS positioning, the position determination can be done in a cycle required by a particular designer. For example, a predetermined time period can be selected, and once the time period has elapsed, a position determination is completed. More specifically, one or more DEVs capable of GPS can be constructed to send a position to pNc every n seconds (or minutes, or select any time interval). Similarly, the distance correction can be done for one or more devices after the predetermined time period has elapsed. This method can be fined, and the dynamic change of the relative position between each other is made every time. In this way, the peaks of the garments can be updated as needed/or the appropriate contours can be selected to accommodate changes in the apparatus to ensure efficient operation of the entire system in response to any changes in the position of the shot. Figure 11A is an embodiment of changing the profile based on changes in the relative position of the devices within the piconet. This embodiment shows how the communication between the PNC 201 and (4) 2〇2 at time 1 is managed by the profile 丨. Then, at time 2, the DEV 2〇2 37 1261435 changes the position of the PNC 201. Then, at time 2, contour 2 is selected to manage the communication between PNC 2〇1 and DEV 202. Profiles 1 and 2 can be completely different, or the difference can be as small as the one contained therein. For example, each contour can have an associated data rate, modulation density, code rate, TFC, or some other parameter.

I When switching from contour 1 to contour 2, one or more of these parameters (or all parameters) in the contour can be changed. Figure 11B shows an embodiment of p2p (peer-to-peer) communication between two DEVs (user piconet devices) in accordance with its relative position within the piconet in accordance with the present invention. In the present embodiment, the PNC 2〇1 manages the communication between the PNC and the DEV 1 202 and the DEV 2 204 by means of the profile. Pnc 201 then directs one or both of DEV 1 202 and DEV 2 204 to support p2p communication therebetween. However, the PNC 201 is positioned relative to each other by the DEV 202 and the DEV 2 2〇4, and then the PNC 2〇1 directs it to manage communication therebetween by the wheel 2 . This embodiment shows how to utilize and select different profiles depending on the relative position of the communication devices in the area. It is assumed that the DEVs are separated from each other by a distance between them and the PNC, which can support a data rate higher than the data rate between them and the PNC 201. The tributary rate 2 associated with profile 2 may be higher than the data rate 丨 associated with profile 丨. In addition, the modulation density 2 of the contour 2 _ may be as strong as the contour 1 (such as having a higher modulation density), and the code associated with the contour 2 = the code associated with the non-rotation 1 is reluctant (if Less redundancy or parity). 38 1261435 It is assumed that the communication link between user devices 1 and 2 (slave) does not require this protection (if its noise may be less, etc.) to support higher data rates, thus providing faster information transmission. The embodiment can also support one of the DEVs that seeks to communicate with other DEVs through the PNC. Therefore, the pNC unilaterally guides them to support p2p communication while considering the relatively close privateness of the DEVs. A p2p communication request is issued from any of these DEVs. Figure 10C is another embodiment of piconet management within a location based on the present invention. This embodiment shows how the PNC 201 acts as a repeater (e.g., filter and amplification) in point-to-point communication between the devices DEV1 202 and DEV2 204. The PNC 201 can independently determine the relative position of the device (DEV1 2〇2 and DEV2 2〇4) relative to the PNC 201, and then the pNC 2〇1 can be unilaterally interposed as a repeater to ensure higher communication between devices. performance. All of the various embodiments described herein benefit from the location of the known devices within the region. In general, with this information, it is possible to operate in this way to achieve the maximum possible data throughput and the most efficient profile. It also enables the most efficient use of the performance and processing resources of the different devices included. The eleventh figure is a complementary embodiment in which the degree of shoulder garment is changed according to the position of one or more of the devices within the piconet. The modulation density spectrum involves a higher order modulation density and a modulation density of the rut low P white. For example, the modulation density spectrum ranges from i〇24QAM (positive 39 1261435 intermodulation amplitude), 256QAM, 64QAM, 16QAM, 8PSK (8 phase shift keying), QPSK (quadrature phase shift keying) to BPSK (binary displacement phase keying) ). Other modulation schemes may be similarly employed and arranged in order of increasing density/descending order without departing from the scope of the invention. Higher order modulation densities may include l〇24QAM and 256QAM. Lower order modulation densities can be considered to include 8psK, QPSK and BPSK. In some embodiments, higher order modulation densities may be considered to include only 16QAM, while lower order modulation densities may be considered to include QpsK and/or BPSK.

Higher order modulation densities can be used in the pass link without relative D-son and/or interference. For example, in a communication link with little noise, using a high modulation degree allows %C to be larger than the throughput. Conversely, lower order mineral density is available; noise and/or interference is large in the communication link. These lower order modulation densities make the data transmitted over the communication link more robust. " It should be pointed out that 'there are many factors that can modulate the density so that the modulation density varies within the enclosure'. These factors include that the devices become far apart (eg, ^^

Dynamic), communication link. The voice becomes louder, or some other limiting factor, to the extent that it is; the knowledge of the robustness of the communication link, so that the 'may suffer or data collapse. Pass the _ road to the passing wheel; = above the #_ flip, flip through (in this 系 系 = 之 何 何 何 何 何 何 何 何 何 何 何 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 40 1261435 The twelfth figure is based on the position of the device in one or a plurality of piconets. How does the actual paste complete the contour change (parameter change) on the spectrum? Each porch, tuned, has a code rate code that provides redundancy (as in the case of four), TFC, and any other one or more of the parameters required in a given real =. The spectrum can be divided into several discrete planes, from high-order secondary corridors to low-order secondary rounds. For example, higher-order rounds provide communication with higher f-volumes (such as less product, higher reliability, etc.). Higher data throughput on the keyway. 2 Order contours can be used for wireline recordings (eg, noise drums, low reliability, etc.) for communication on communication links. For example, 'high order rims and lower order second rounds When comparing, 'higher order contours have more __, higher modulation density (eg, More constellation points, higher order codes (eg, more redundancy or parity), a more robust tfc when comparing straight TFCs to lower contoured TFCs. " The proper profile change management device Inter-communication, recovery _ more than the face is changed in terms of density in the above embodiment, the same as the above, such as: With the two devices farther apart, the communication link D Sanyin is larger or other suitable reasons can choose different corridors More specifically, if the relative distance between the two communication devices becomes larger, a more robust (order: lower) profile can be selected to manage the future communication of the two splicing. Similarly, if the two communicate with each other The relative distance becomes smaller, then 41 1261435. The = unsteady (higher order) wheel corridor manages the two devices in the future. The two π's used to manage the communication between devices can be based on the communication system. The position of the product is adjusted. Again, in the month of the invention alone, the other considerations can be heard to guide the choice of the alternative wheel #. In some cases, only one parameter in the wheel grinding is required to be changed according to the consideration. Thirteenth_piconet The embodiment shows a predetermined limited set of contours (and corresponding parameters) stored in the non-y-set according to the present invention. This embodiment shows that the right-hand clustering can include both the two devices (four) Corresponding information. For example, the PNC 201 includes information corresponding to the contour i, the corridor 2, the corridor '-··· and the contour η. Similarly, the parent of the DEV in the communication system includes the wheel # 1 , contour 2, rim 3, ._· and the corresponding information of the wheel η. Thus, to support communication between any two of these devices, both devices have information corresponding to the appropriate contour, so that It can be efficiently communicated (eg, 'all with the same data rate expected to be one or more, the same code, the same modulation density, and/or the same TFC.) As an example, the PNC 201 can communicate with the DEV 1 202, Both PNC 2〇1 and DEV 1 202 use contour 2. Similarly, the PNC 201 can communicate with the DEV 2 204 such that both the PNC 2〇1 and the DEV 2 2〇4 employ a contour n. Similarly, the PNC 201 can direct the DE ν 202 and the user device 2 to complete the ρ 2 ρ communication therebetween, so that the DEV 1 202 and the DEV 2 2 〇 4 both use the contours in the Ρ 2 ρ communication to provide different contours to each device. Corresponding information can support effective communication between them 42 1261435. Fig. 14, Fig. 15, and Fig. 16 are flowcharts showing different embodiments of the WPAN (Wireless Personal Area Network) management method completed in accordance with the present invention. Referring to Figure 14, the method begins by determining where each of the WPANs are located. It may involve the relative position of different devices to each other or the specific location of these devices. It can be done in different ways. For example, the position of a particular device can be determined by triangulation. Or, it may involve the determination of the radial distance from the PNC to the different DEVs. In still another embodiment, it may involve a GPS (Global Positioning System) function embedded in a different device to determine its specific location in a certain degree of precision provided by the Gps function. The method then continues to divide the different devices into groups based on their relative or specific location within the WPAN. For example, it may involve grouping DEVs based on the distance from the PNC. Or, it may involve grouping the DEVs according to their specific locations within the wpAN. The method then assigns contours to correspond to one or more groups divided by the device. The method then supports communication between the pNC and one or more of the DEVs within the group by the assigned profile. Alternatively, the method may involve supporting communication between DEVs within one or more of the groups by means of a contour of the knives. It also supports the communication between the two DEVs by one or more of the assigned profiles. 0 1261435 Referring to the fifteenth figure, the method supports one or a plurality of intra-group PNCs from the profile assigned by the wpAN. Communication with one or more DEVs begins. The method continues to monitor the relative or specific location of each device within the WPAN. It may involve determining the position of the wire by triangulation. Or, it may involve determining the radial distance from different DEVs starting from the PNC. The method then continues to detect changes in the relative or specific position of the various devices within the WPAN; this can be achieved by the completion of the corrections after each lapse of time. The method then involves the assignment of a change (or round_parameter) according to any change in the relative or specific position of each device within the WPAN, if necessary. The method then follows the mosquito new/changed distribution profile pNc and one or more groups of one or more packages of communication. Again, it may involve establishing a p2p communication between two DEVs by the PNC. Referring to Figure 16, beginning, the method can follow one of two possible paths. Stone-road control, this method uses triangulation to determine the specific location of each device in the chat. Alternatively, the method can use the Gps (Global Positioning System) = in the device to determine the specific location of each device within the WPAN. Regardless of which method is used to determine the specific location of each device within the WPAN, then the method involves all DEVs from the wpan from one or more of the positive transmission locations. Then the method involves a request for communication between the two DEVs by the PNC; 44 1261435 or the method involves unilaterally directing communication between the two devs by the PNC. Then, in a decision box, the method determines whether the two devs are at the forefront of each other. If the fine device is in the Huanfan, the Lin method continues to use the PNC's and also establishes the Qing communication between the two devs through the first corridor. If possible. If the two DEVs are not within a predetermined distance from each other, the method continues to support communication between the two by the PNC' and also by the second profile (e.g., the gallery 2). If necessary, it involves using the PNC with the _ pedal communication key relay. It can be completed when the ten DEV supports the ρ2ρ communication between them. It should also be noted that the various methods described in the fourteenth, fifteenth, and sixteenth aspects of FIG. 16 can also be accomplished in the apparatus and/or system embodiments described in other portions of the system. The above invention is in accordance with the invention, and the method is as follows: Within the scope of the following patent application.
