This patent application claims the priority of provisional application No. 61/028480, which is entitled "METHODS AND APPARATUS FOR HEADER FORMAT BASED ON PACKET SIZE", filed February 13, 2008, assigned the copyright holder for this application and is hereby expressly included in the materials of the present application by reference.

Prior art

In some wireless communication systems, the signals are transmitted in the format frame. Within the frame format information is divided into packets and formatted according to the actual data payload to be transmitted over the communication system, and other proprietary information, which is used to transmit various information specific to the communication system, such as information used, for example, to obtain synchronization and decoding of the frame. This service information as a rule, is located in the packet header within the frame and is connected to suitable the m data packet payload, belongs to the header information.

In some types of communication having a low data rate (and the small size package), such as voice over IP (VoIP), for example, it is desirable to minimize the service header information to increase system throughput, for example, to support a larger number of VoIP calls in the system. In addition, it is noted that the levels control the medium access (MAC) and higher frames are organized so that the headers will be correctly formatted in order processing immediately before the associated data packets or payloads. In communication systems having a higher data transfer rates and large packet sizes, however, the size of the header, of course, increases for processing large packets in the receiver. The typical format with headers, organized for processing before each corresponding data packet, which is favorable for communication c low speeds, tends to slow down the processing of large packages and their big titles in the receiver during communication with high data transmission speeds. Accordingly, there is a need to coordinate and transmission of low speed data transmission, and transmission of high speed data transmission in the communication system, at the same time providing a mechanism to enhance the processing of the header for transmission of high speed data transfer.

DETAILED DESCRIPTION

According to the aspect, now disclosed methods and apparatus provide the formatting of a frame, which provides optimized processing for frames received at the mobile device, such as, for example, the access terminal (at). This is achieved through the format of a frame that includes a header at the beginning of the wireless frame in front of the packet payload, especially for frames with large packets payload and, thus, a larger frame size. When processing in the receiver, this format provides more efficient processing than in the case when the frames are arranged so that each header is placed with its associated payload. In another aspect, disclosed here are methods and apparatus provide the formatting of a frame, which depends either on the full size of the communication frame (e.g. frame MAC)or on the size of the pack is impressive payload within a single communication frame. If the frame or packet payload in the frame are smaller, such as for communication according to VoIP, the headers are in conjunction with their associated package payload, in order to optimize the size of the header. On the other hand, if the communication frame or packet payload within the frame are great for high-bandwidth data, such as UMB, or LTE, the frames are arranged alternately to include all the headers in the first place in the frame to packet payload, to optimize the ability of the receiver processing the frame. Thus, the formatting of a frame adapted to be optimal for the type of communication carried out with the frame.

In the following described examples, for reasons of consistency and clarity in the disclosure uses some of the terminology associated with the technology ultra mobile broadband (UMB). It should be emphasized, however, that the examples described here are also applicable to other technologies, such as technologies associated with Long-term Development (LTE), Multiple Access, Code Division multiple access (CDMA), cdma2000 EV-DO, Multiple Access with time Division multiplexing (TDMA), Multiple Access, Frequency Division multiple access (FDMA), Multiple Access with Orthogona inim Frequency Division multiplexing (OFDMA), etc. Specialists in this field will be clear that when applying the disclosed methods and devices for other technologies the corresponding terminology will undoubtedly be different. As examples, the access point (AP) may be a fixed station used for communicating with the terminals and may also be referred to the access point, Node B, a base station or some other terminology. The access terminal (AT) may also be called an access terminal (AT), user equipment (UE), a wireless communication device, terminal, access terminal or some other terminology.

According to the aspect, Figure 1 illustrates a system 100 for wireless communication, which can be used are disclosed here are methods and devices. Access point (AP) or base station 102 transmits the information to the terminal 104 via direct lines 106, 108 communication. The transmitted information may be arranged in communication frames for packaging data.

Access point (AP) may be a fixed station used for communicating with the terminals and may also be referred to as an access point, Node B, a base station or some other terminology. The access terminal (AT) may also be called an access terminal, user equipment (UE), a wireless device, t is renala, access terminal or some other terminology.

Figure 2 illustrates an exemplary format of the frame control the medium access (MAC) (and above)that can be transferred, for example, AP 102 in the system of figure 1. The frame 200, in particular, is exemplary format for UMB to optimize headers, for example, for smaller packets payload. As discussed above, for communication according VoIP uses smaller packets payload, but the frame 200 is not restricted to this, and it is optimal with various other types of communications that are sensitive to synchronization like voice. As shown, the frame 200 MAC includes one or more header frame 202 (shown only for short) for each packet within the frame 200. The header 202 are referred to as Protocol headers Consolidation Package (PCP), are the first in the frame 200 and are used to specify where to find the various "n" of data packets within a communication frame 200. After the header 202 of the first header 204 is shown positioned directly in front associated with him or the corresponding payload data 206. Headers, as will be explained later, can be configured according to the Protocol of the Line Radio, Streaming Protocol, Protocol fragmentation and re-Assembly is, or Protocol identification of logical channels, for example. A pair of header - payload", such as the header 204 and a payload 206, can be called as a "package" and, more specifically, the MAC package in this example.

After the payload 206 the following header 208 and the corresponding payload 210 are received in sequential order the flesh to the n-th header 212 and corresponding payload data or packet 214. After the steam header and payload data of the end portion 216 of the MAC frame 200 may be enabled to determine or indicate the end of frame 200, or at least the end of the n payload data within the frame 200. Full size frame 200 is illustrated in Figure 2 dimension 217.

Figure 2 also illustrates an expanded or enlarged view of 218 approximate header top level, which is applicable to all titles of the frame 200, such as the header 204. As can be seen, the header 218 includes a number of fields, some of which are variable in length in bits and depend on the size of the payload or data packet to which it corresponds. Accordingly, this allows the header to be changing according to the specific size of the payload data or package.

As shown, the header 218 may include a Header 220 Route, which has bits of the Route variable length in bits, that the decrees which determine a route to the destination of the package. The header 218 may also include a Header 222 Thread to indicate the flow that corresponds to this package. In addition, title 218 includes a Protocol header line communication (RLP), which includes the Index 224 encryption Key Field 226 Sequence Segmentation and reassembly (SAR), box 228 First + Last and header 230 Fast Negative Acknowledgement (QN). The RLP header is extracted or obtained from a level other than level MAC, and added to the header 218. Various fields in the header of the RLP may also be variable based on the size of the package, such as region 226 SARSeq or Header 230 QN. It should be noted that the RLP header received from other levels (e.g. level RLP or when building headers for frame 200 level MACS).

It is also noted that the header 202 PCP can also be formatted so that it included information field (not shown) to indicate whether there is more than one PCP header in the frame 200. The header 202 PCP may also include short or long length field, which is used to specify the increased length of the payload in the case of long fields to support the large size of the payload Module Data Protocol Segmentation and reassembly (SAR PDU). As an example, the length field in the header of PCP may be 6 bits in length DL is instructions for a shorter length of a payload of up to 64 bytes and the length field is 14 bits to indicate greater lengths payload up to 16384 bytes.

Figure 3 illustrates an alternative exemplary format of the frame control the medium access (MAC) (and above)that can be transmitted from the AP 102 in the system of figure 1, for example. In particular, the frame 300, which in this example is a MAC-layer frame for the UMB system, configured or formatted so as to provide optimized processing on the receiver side, receiving and processing the frame. As can be seen in figure 3, the frame 300 includes "n" headers (302, 304, 306 inclusive), located at the beginning of the frame 300 before their respective payloads (308, 310, 312). As was discovered by the inventors, this is the location of the headers and payloads within the communication frame, such as frame 300, provides optimization processing on the receiver side, demodulateur and decoding the frame.

The frame 300 may also include package 314 the Number of Headers at the beginning of the frame (for example, single-byte field indicating the number of data packets in the frame 300). Package 314 reports the number of packet headers (i.e., the number "n") in the frame 300. The frame 300 also includes an end portion 315 MAC, which completes the frame 300.

Also figure 3 shows an expanded view of 316 typical header, such as header 302. As shown views 316, the header includes for the of olook 318 PCP, which can be used to communicate information PCP to another level, as well as information about the route header. The header may also include the RLP header having a backing field 320, box 322 Index Key Cipher, box 324 First + Last field 326 of cryptocephalinae (Cryptosync). In addition, within the field Cryptosync various bits (not shown) can be used to specify the code of the function, direction, counter to the router ID of the thread Counter Reset SAR and virtual number sequence SAR. It should be noted that in the example Cryptosync can be installed with a length of 96 bits.

In addition, according to the aspect, the length of the header in the frame 300 may be set equal to a fixed size, to improve the optimization processing performed by the receiver. When fixing the size of the header processing in the receiver additionally optimized, since the fixed size provides predictability for the processing of the receiver and is used to prevent bottlenecks in the processing performed by the receiver. Specific length headers can be set in accordance with a specific system or type of communication performed by the communication frame.

Figure 4 shows how the format of a communication frame that can use the base station, access point, or other transmitter of the communication system such as communication system or LTE UMB. As shown, determine the size of the subject Assembly frame for wireless communication, such as a MAC frame, as shown by step 402. It is noted that this determination of the amount can be based on a full size frame wireless communication (e.g., 217), or, alternatively, the sizing can be based on one or more of the dimension(s) payload data in the communication frame. As another alternative, the size determination at step 402 may be based on known whether the type of communication (for example, broadband is associated with a large frame size). Thus, if the connection is a broadband connection, such as in systems UMB or LTE, it is known that the frame size is large compared to the other communications, such as VoIP.

According to the method according to Figure 4, the MAC frame reassembling, and a lot of headers, each corresponding to a respective payload MAC, have in the communication frame before many payloads MAC, when a certain frame size is greater than a predefined threshold, as shown by process step 404. As discussed above, by placing all MAC headers before any of the payloads MAC, as illustrated by the example in Figure 3, the processing of the communication frame can be optimized in the receiver.

According to an alternative aspect, determining the size of the stage 402 may be based on determining the size of at least one of the payloads and headers, not the full size of the communication frame. Accordingly, the decision to format the frame, placing the headers before any useful loads at stage 404, it would be based on that, does that at least one of the size of the payload and the header is greater than a predefined threshold.

As an example of the process by which a payload of the MAC can be generated or collected in the process in steps 402 and 404, Figure 5 illustrates a sequential series of frame Assembly when passing through multiple levels. It should be noted that the terminology used in this example, refers to the communication systems LTE, but the concept it is not limited and may apply to UMB or any other suitable communication systems. As shown, packet data 502, such as an IP data packet is associated, or is appended to the header 504 Protocol Packet Data Convergence (PDCP) at the level of the PDCP. This header 504, as an example, may include a Sequence number (SN) of the PDCP. In a further aspect, the SN may have a length of 7 or 12 bits, depending on the logical channel. Linking data packet 502 and PDCP Header 504 in a couple may or may not order the conclude in itself added the end part with the checksum security (for example, A 4-byte field).

With a pair 502, 504 is then associated or add the header 506 control line radio (RLC) at the next level RLC. Finally, the United RLC payload, consisting of a header 506 RLC, header 504 PDCP, package 502 data or multiple payloads RLC (not shown), can then be collected for use as payload 508 MAC at the MAC level. As can be seen in this example, the payload 508 MAC, designated as payload 1 MAC, connected with the header 510 MAC. As further shown, payload 2 MAC (512) is also a communication frame with its associated header 2 MAC (514), which is located in front of a payload MAC (508, 512).

6 illustrates an exemplary header that can be used for various heading levels shown in figure 5. Again, as in Figure 5, the terminology used in this example, refers to the communication systems LTE, but the concept is not limited to it and can relate to UMB or any other suitable communication systems. As shown, the header 602 PDCP includes field 604 management of the 4-bit field 606 serial numbers, having either 7 or 12 bits. Header 608 RLC-specific mode, such as Sequiterpenes Mode or VoIP, may include field 610 controls with 3 or 6 bits, and the field 612 then kovago number of 5 or 10 bits. Another alternative for RLC header for Quaterwave Mode, such as FTP/TCP, shows the header 614 having a control field of 6 bits and a sequence number of 10 bits.

Header 616 MAC may consist of field 618 controls with 3-bit field 620 logical channel ID, which is 5 bits in length, and field 622 length of 7 or 15 bits. In addition, the size of the headers can be fixed to the large size of the data packets. Thus, in example 6, the sequence number 606 RLC would be set to 10-bit sequence number 604 PDCP installed in 12-bit field 622 of the length of the MAC header is 15 bits.

According to another aspect, the format of the communication frame can be made depending on the size of the packet payload data to optimize the formatting for the types of communications. When the frame payload are small, such as in the case of communication according to the VoIP communication frame may be formatted according to the first format, such as format to optimize specify the size of the headers. Conversely, when the payload is large, such as in the case of connection with high bandwidth, the communication frame can be an alternative formatted according to another format, such as format to optimize processing of the frame in the receiver.

7 shows a logical block is J. such an exemplary method for use in formatting the configuration of headlines in the communication frame, depending on the size of the communication frame. As shown, the size of the formatted communication frame is determined at the step 702. After determining the size of the communication frame, the process goes to step 704. At step 704, at least one label corresponding to at least one data packet format according to the first format, when the packet size is less than the predefined size, and according to the second format when the packet size is equal to this predetermined size or more. Predetermined amount depends on the communication system and related standards. As examples only, obviously large packs order 4000-6000 bytes in communication according to UMB or LTE would be above a predetermined threshold, whereas a much smaller packages VoIP 40-50 bytes would be significantly below a predetermined threshold.

According to the aspect, the first format may include volatile configuring the size of the at least one header, based on the length of the corresponding at least one data packet. As the example in figure 2, the header 218 in the optimized format of the header uses a variety of fields of variable length so that the size of the header can be set or adjusted based on the size of the data packet. This flexibility provides the opportunity to ensure that the header size is optimized to be as small as possible on the I of the specified data packet. In addition, the first format in step 704 may also include grouping at least one header with a corresponding at least one data packet within a communication frame, as illustrated by the example of the frame 200 in figure 2, which satisfies the specific types of communication, such as communication via voice over IP.

According to another aspect, the second format at step 704 may include placing at least one header in the communication frame before and independently from the corresponding at least one data packet. Thus, each header corresponding to the data packet is separated or made independent of the data packet and placed before the data packets or payloads in the communication frame. An example of such a format is illustrated frame 300 MAC figure 3. In the separation of headers and associated payloads or data packets, especially in the case of large data packets used in the communication (for example, TCP/IP), the resulting benefit is a more efficient processing of the communication frame in the receiver, since the processing of the header can be started while waiting for the reception of the actual payloads that will be demodulates and decoded.

In the example, the second format at step 704, the size of ENISA least one header may be set to a prescribed fixed length, such as that discussed above in connection with the example of the MAC header in Figure 5. When you install headers in a fixed length receiver provides benefits consisting in predictability. When the size of each header is known to the receiver, requires less processing to determine how many bits will be present in the header, thus contributing to further optimize processing.

According to another aspect of the second format at step 704, the header format of the second information used by the receiver of the communication frame to encrypt or processing at least one data packet is contained within at least one title. As an example this particular, Figure 3 shows that the header 316 includes the header 318 PCP within each heading, so that information about PCP and the Route is contained within each respective title. Accordingly, the header processing can be optimized, and the headers can be independent from the other titles and, more importantly, from their respective data packets. This causes the contrast-optimized header of the format of figure 2, where the headers 220 PCP are separate from the headers (e.g., 202) and processed before processing group header and packet data.

Fig Illus who demonstrates exemplary transceiver 800, which formats and transmits the communication frame based on the size of the data packet in accordance with the formats and methods disclosed here. Transceiver 800 may represent an access point (for example, AP 102 in figure 1), base station or other suitable hardware such as a processor or set of circuits/modules), software, firmware, firmware or any combination thereof for use in the AP device. As shown, the transceiver 800 includes a Central bus 802 data or similar device for the communication connection or pairing several circuits together. The circuit includes a CPU (Central processing unit) or the controller 704, the transceiver circuit 806 and the memory module 808.

The transceiver circuit 806 includes a receiver for processing received signals before they are sent to the Central data bus 802, and a transmitting circuit for processing and buffering data from the bus 802 data before sending them out of the device 800, for example, to one or more access terminals, as shown wireless line(s) 810 connection. Accordingly, the circuit of the transceiver 806 may include a radio frequency circuit for transmission over the wireless line 810 due to one or more access terminals.

CPU/controller performs the function of data management bus data 802 and, in addition, the function of General data processing, including the execution of the instructional content of a memory module 808. Here, we note that instead of a separate implementation, as shown in Fig as an alternative schemes transceiver 706 may be integrated as part of the Central processor/controller 704. As a further alternative, the entire apparatus 700 may be implemented as a specialized integrated circuit (ASIC) or similar device.

The memory module 808 may include one or more sets of instructions/modules. In an exemplary device 800 instructions/modules include, among other things, the function 812 format frame, which is configured to perform the techniques described here, namely the formatting of a frame discussed above in conjunction with Figure 2-7. In the example on Fig memory module 808 may be a scheme of RAM (random access memory). Approximate parts, such as the functions in block 812, are software procedures, modules and/or data sets. The memory module 808 may be associated with another schema memory (not shown), which may be volatile or non-volatile type. As an alternative, the memory module 808 may be made of the circuits of other types, such as EEPROM (electrically erasable programmable read only memory), EPROM (electrically programmable memory only lactemia), ROM (read only memory), ASIC (specialized integrated circuit), magnetic disk, optical disk and other computer-readable media known in the art.

Fig.9 shows another example of the device for use in a transceiver in a communication system, which can be used for formatting headers in communication frames. It is noted that the device 900 may be performed in the access point or base station, for example. It should also be noted that the described device 900 is not limited to an implementation only in the access point or base station, but may also be implemented in any suitable hardware, which formats the communication frames to send.

The device 900 includes a module or means 902 for determining frame size wireless (or, alternatively, the size of one or more payloads of data within a communication frame). As an example, the tool 902 may be implemented with one or more components within the transceiver. As an example Fig, memory 810 in conjunction with the Central processor/controller 804 may provide a means 902. Information defined by the tool 902 may then be communicated to various other modules or tools in the device 900 via the bus 904 or similar suitable communicatio is a great pair.

The device 900 also includes a means 906 for formatting a communication frame to include one or more headers at the beginning of the frame before any data packets in the frame, when a certain frame size wireless is above a predetermined threshold. Alternatively, the means 906 may determine that the size of one or more payloads of data is above a predetermined threshold to decide to format if the headers at the beginning of the frame. It should be noted that the tool 906 may perform the processes of step 404 and formatting shown in Figure 3, or 5, as examples. Like the tool 902 above, the tool 906 may be implemented with one or more components within the transceiver, and, more specifically, with those who carry out the Assembly or organization of communication frames, including frames MAC. As an example on Fig, memory 810 in conjunction with the Central processor/controller 804 may provide a means 906. The tool 906 may communicate with the transceiver circuits 908 to transmit a communication frame having the desired formatting performed by means 906.

In addition, the device 900 may include an optional machine-readable medium or storage device 910, configured to retain the machine-readable instructions and data for effecting the processes and behavior of one or more of the modules in the device 900. In addition, the device 900 may include a processor 912 configured to execute machine-readable instructions in the memory 910, and thus, may be configured to perform one or more functions of the various modules in the device 900.

Figure 10 shows another example of a device 1000 for use in a transceiver in a communication system, which can be used for formatting headers in communication frames. It is noted that the device 1000 can be implemented in the access point or base station, as examples. It should be also noted that the open device 1000 is not limited to an implementation only in the access point or base station, but may also be implemented in any suitable device that formats the communication frames to send.

The device 1000 includes a module or means 1002 for determining frame size wireless MAC. In an alternative aspect, the size of one or more payloads of data that must be placed in the communication frame can be determined by means 1002. As an example, the tool 1002 can be implemented with one or more components within the transceiver. As an example Fig, memory 810 in conjunction with the Central processor/controller 804 may provide a means 1002. Information, the definition is by means 1002, may then be communicated to various other modules or tools in the device 1000 via the bus 1004 or similar suitable communication pair.

The device 1000 also includes a means 1006 for formatting header corresponding to the at least one packet according to the first format, when the frame size MAC wireless communication is below a predetermined size, and formatting at least one header according to the second format when the batch size is equal to or greater than a predetermined size. It should be noted that the means 1006 may perform the processes of step 704 7 and formatting, as shown in figure 2 and Figure 3, or 5, as examples, depending on the size of the communication frame.
