This application claims priority of the provisional application entitled "IEEE 802.16 based wireless subscriber station for short range ad-hoc data communication", filed June 2, 2006 with a serial number 60/810330.

The technical field to which the invention relates

Embodiments of the present invention relate to systems for wireless data transmission. More specifically, embodiments of the invention relate to a wireless decentralized data transmission.

The level of technology

The 802.16 standards of the Institute of engineers on electrical and electronics (IEEE) describe the radio interfaces for systems of fixed and mobile broadband wireless access, especially for the regional network (MAN) or wide area network (WAN). There are different standards for wireless personal area network (PAN) and wireless local area network (LAN), such as IEEE 802.11, known as Wireless Fidelity (Wi-Fi), IEEE 802.15, known to the public as Bluetooth. Both Bluetooth and Wi-Fi include the Protocol is a decentralized network, so that the user terminal can communicate with another user terminal directly without an access point. A subscriber station (SS) of the IEEE 802.16 standard can transfer data directly between the SS, using the grid mode is. However, the Protocol is so complex that industrial standards, such as global interoperability of broadband wireless access (WiMAX) and wireless broadband (WiBro), did not accept the grid mode.

Equipment such as Bluetooth and Wi-Fi, basically can not carry data, if SS is on small distances (e.g., 300 feet) from the access point. The IEEE 802.16 standard is designed to cover tens of miles. Therefore, the IEEE 802.16 equipment can theoretically replace equipment Bluetooth and Wi-Fi, but not Vice versa.

Decentralized network includes a fixed or mobile subscriber stations (SS), which are located close to each other. Decentralized network with short-range does not have a base station (BS). Instead, it has a server of a mobile station (SMS). SMS opens the wireless channel, which includes continuous frames of fixed duration in time. These frames start with long preambles, followed by the control frame header (FCH). Each FCH contains a label or identifier to represent a decentralized network, so that neighboring SS can distinguish a decentralized network from the infrastructure network, formed through the BS.

The first MS may be MS that performs the process 400. Then the process 400 performs entering data in a decentralized mode with simplified data transfer Protocol of the broadband wireless standard (block 420). Then the process 400 transmits the data to the second MS using the data in decentralized mode (block 430). The process 400 then ends.

Figure 5 is a block diagram of the sequence of operations illustrating the process 410, shown in figure 4, to configure a decentralized mode according to one variant embodiment of the invention.

The operating mode may be a manual mode or automatic mode. Manual mode allows the user us is enableval, to MS mode was MS or SMS in a decentralized network. Automatic mode is first automatically searches for the SMS. When there is no SMS, discovered during the search period, the device itself installs itself as SMS. When there is at least one SMS, discovered during the search period, the device allows the user to select SMS. Then, the process 510 is completed.

6 is a block diagram of the sequence of operations illustrating the process 420, shown in figure 4, for entering data in a decentralized mode according to one variant embodiment of the invention.

When operation is Started, the process 420 determines the operating mode (block 610). The operating mode can be any one of a manual mode and automatic mode. Manual mode is a mode in which the operation mode is set manually or by the user or by default. The operating mode may be a mode MS, the SMS mode or automatic mode.

If the operating mode is MS, the process 420 searches the one or more SMS during the search period (block 625). The search period may be set by default. Next, the process 420 determines whether the detected SMS (block 630). If Yes, the process 420 displays all discovered SMS on the display, allowing the user to select (block 635). In FR the main case, the process 420 moves to block 640. In block 640, the process 420 determines the choice of the user. If the user selects the next search, the process 420 returns to block 625 to continue searching the other SMS. If the user selects the end, the process 420 is completed. If the user selects the SMS, the process 420 proceeds to block 660.

If the operating mode is SMS, the process 420 searches available or empty frequency channel (block 670). Next, the process 420 begins sending data in a decentralized mode as decentralized SMS (block 675) and then exits.

If the operating mode is automatic, the process 420 searches the SMS during the search period (block 645). The search period may be set by a timer. Next, the process 420 determines that the detected whether SMS during the search period (block 650). If not, the process 420 proceeds to block 670. Otherwise, the process 420 displays all discovered SMS for selection by the user (block 655). Next, the process 420 allows the user to select SMS (block 660).

7 is a diagram illustrating the simplified structure 700 frame according to one variant embodiment of the invention.

Message 710 PDU PHY DL includes preamble 752, managing header 754 frame (FCH) cluster 756 DL. FCH 754 can be used to describe the cluster 756 DL and the number of MS in a decentralized network 140. This information is used to calculate the offset in time, as described below. FCH 754 can also be used for storing the modulation type of each cluster UL instead of the message descriptor channel uplink communication (UCD)the UCD message may be excluded. FCH 754 can also be used to store the type of modulation cluster DL, so that the message descriptor of the channel downlink (DCD) may be excluded. The cluster 756 DL includes a broadcast message 762, N PDU 1 MAC PDU MAC N 7641-764Nand the placeholder 766. The cluster 756 DL packs all messages PDU MAC DL. These fields of the message can be parsed for data transmission in a decentralized mode, as described below.

PDU 730jPHY UL includes preamble 772, cluster 774 UL and the gap 776 division of the SS (SSSG). The process of selecting the range can drop through the distribution interval of the cluster UL PDU 730jPHY UL sufficiently long to eliminate the effect of delay spread, to the which can cause a conflict between the message PDU PHY UL, each sent to a different MS. PHY SMS can synchronize PDU PHY UL, even if they do not arrive exactly at the border of each scheduled start time of the cluster UL by joining the preamble 772 at the beginning of the PDU 730jPHY UL. Preamble 772 long enough to SMS discovered clocking, frequency shift power etc., which is also necessary to exclude the selection process of the range.

Figa is a block diagram of the sequence of operations illustrating the process 430, shown in figure 4, to transfer data to another MS according to one variant embodiment of the invention.

When the operation Start, the process 430 may perform at least one of the multiple tasks easier in blocks 820, 830, 840 or 850. These tasks easier, provide simplified data transfer Protocol of the broadband wireless standard (e.g. IEEE 802.16), used by MS in a decentralized network 140. The process 430 can simplify the initial band selection (block 820), the message broadcast control (block 830), the network input (840) or the distribution and planning of the frequency band (block 850). The process 430 then exits.

FIGU is a block diagram of the sequence of operations illustrating the process 820, shown in Figa, simplify range according one is the variant embodiment of the invention.

After the operation Start of the process 820 may perform at least one of the operations or actions in blocks 822 and 824. The process 820 may distribute the interval cluster UL sufficiently long to prevent conflict between PDU PHY UL, each of which is transmitted from a different MS (block 822). The process 820 can attach a long preamble at the beginning of the message PDU PHY UL, contributing to the detection and decoding PDU PHY UL SMS (block 824). Then, the process 820 is completed.

Figs is a block diagram of the sequence of operations illustrating the process 830, shown in Figa, to simplify messages broadcast control according to one variant embodiment of the invention. IEEE 802.16 enter the access Protocol to the transmission medium DL (DL MAP), UL MAP, the message descriptor of the channel downlink (DCD) and descriptor channel uplink communication (UCD). MAP DL includes information about the coding of clusters DL and UL MAP includes information about the coding of clusters UL. DCD and UCD include information on the channel downlink and uplink communications respectively. The transfer of these messages broadcast management presents its own functional capacity of the BS, which may not be required when transferring data in a decentralized mode, and can strengthen Atsa or excluded.

After the operation Start of the process 830 may perform at least one of the operations or actions in blocks 832, 834, 836 and 838. The process 830 may exclude messages MAP DL by packing all messages PDU MAC DL in a single cluster DL (block 832). It is shown in Fig.7. The only cluster 756 DL (7) includes a broadcast message 762 and a unicast message to the MS in a decentralized network 140 (Fig 1).

The process 830 may exclude messages UL MAP by calculating the time-shift cluster UL, using the number of MS in a decentralized network and basic connection identification (CID) (block 834). MAP UL specifies the offset and length of each cluster UL and the UL start time that indicates the boundary of the downlink and uplink communication. Information about the time of the beginning of the UL is not required if it does not change from frame to frame and known each station in a decentralized network 140. SMS and all MS operating in decentralized mode, may have a fixed value, the default start time UL, TTG 715, IRNG 720 and RTG 740, as shown in Fig.7. MS can calculate the offset in time of the cluster UL, which is distributed for themselves, using the following parameters: (1) the number of MS in a decentralized network 140, which is set to FCH 754 (Fig.7). FCH 754 has the space to describe up to 4 on the following clusters DL, one of which is used to describe cluster 756 DL, and other fields can be used to describe the amount of MS. MS knows the offset time of each cluster UL by dividing all of the cluster UL on the number of MS; (2) basic CID, which is included in the simplified message IRNG-RSP (response initial range selection)sent via SMS. If the basic CID of the MS is equal to 1, it can use the first cluster for UL transmission.

The process 830 may exclude the UCD message by including information about modulation in FCH (block 836). The UCD message includes a cluster profile UL, which is used for notification of the modulation type of each cluster UL and some channel information. SMS may include modulation types for each or the entire cluster UL in FCH 754 (7), so that optional SMS broadcast to transmit messages UCD.

The process 830 may simplify the DCD message via profile exceptions cluster DL, code, frame duration, gap transition of the transmit/receive (TTG) and gap transition of the transmit/receive (RTG) (block 838). The DCD message includes a cluster profile DL, which is used for notification of the modulation type of each cluster DL and some channel information. SMS may exclude the cluster profile DL, as the modulation type of the cluster DL described in FCH 754 (Fig.7). SMS can eliminate code DL the activity frame, TTG 715, RTG 740, as these values can be set as default values in decentralized mode. SMS can also exclude all other fields to simplify the DCD message, but may include name, SMS"that is not defined in the IEEE 802.16 standard. The name of the SMS can be used to ensure that the MS displays the list of scanned SMS for the user's convenience. The process 820 then exits.

Fig.8D is a block diagram of the sequence of operations illustrating the process 840, shown in Figa to simplify network entry according to one variant embodiment of the invention. During the initialization process has many stages according to the standards of IEEE 802.16. BS decides, and is the response message and transmits it to each request. These tasks are not necessary when transferring data in a decentralized mode and can therefore be parsed.

When operation is Started, the process 840 may perform at least one of the operations or actions in blocks 841, 842, 843, 844, 845, 846 and 847. These operations simplify procedures mains input data in a decentralized mode.

The process 840 may use fixed default frame duration and the index of the cyclic prefix (CP) (block 841). Through the use of fixed values default is the MS can significantly reduce the number of trial combinations during phase search or scan.

The process 840 may exclude information about power, clocking and frequency shift in the response message to the initial band selection (block 842). As described earlier, these data may be excluded in message IRNG, although the basic CID may be included to identify the MS in a decentralized network 140 (Fig 1).

The process 840 may include a basic connection identification (CID) to identify MS in a decentralized network (block 843). IRNG may include the name of the MS, which can be set by the user. The name of the MS is not defined in the IEEE 802.16 standard. It can be used for SMS display a list involved in the data transfer MS for the convenience of the user.

The process 840 may skip negotiate basic capabilities through the use of fixed default values of the mode of automatic repeat request (ARQ)mode of fragmentation and packing mode (block 844).

The process 840 may skip the authorization and registration of subscriber stations (SS) (block 845). SMS and all MS in a decentralized network 140 (1) may not use the control Protocol of the secret keys (PKM). The encryption key payload and the encryption algorithm can be set manually by the user or payload may be encrypted, if the user does not turn on the encryption of the payload.

p> The process 840 may pass an optional process that is defined in the broadband wireless standard (block 846). Optional process includes at least one of establishing connectivity to an Internet Protocol (IP), setting the time of day and forward operating parameters. SMS and MS in a decentralized network can use the installed manually by the user, IP address or automatically generated static IP address, in which the lower byte of the IP address can be derived from the basic CID.

The process 840 may establish a single connection, numbered basic CID (block 847). By the standards of IEEE 802.16 MS has multiple logical connections to ensure quality of service (QoS), which is described by many parameters and is used for BS planned network traffic. They may not be required in a decentralized network. MS operating in decentralized mode, can use only one connection. This is the only connection may be numbered basic CID. This connection can send and receive all types of data flows and control messages.

The process 840 may perform one or more of the simplifications described above. Then, the process 840 is completed.

File is a block diagram of the sequence of operations, Illus ryuudou process 850, shown in Figa, to simplify the distribution and planning of frequency bands according to one variant embodiment of the invention.

After the operation Start of the process 850 sets the type of planning connection to the service access requirements (UGS) default (block 852). IEEE 802.16 define several types of planning, such as the service access requirements (UGS), the survey in real time (rtPS), survey non-real-time (nrtPS), best possible (BE), etc. BS refers to the type of each connection for distribution of Subhadra UL. In addition, the BS receives a request message bandwidth from the MS, retrieves the requested value and decides which frequency band to be allocated to the connection by reference to the history of the transmission and the QoS parameters of the requested connection. These operations may not be required when transferring data in a decentralized mode. In a decentralized network SMS and MS can only use one basic compound as described above. The planning type of connection can be installed on UGS default. Then, the process 850 is completed.
