It should be noted that, in the following embodiments and drawings, components that are not directly related to the present invention have been omitted and are not shown; and the dimensional relationships between the components in the drawings are merely for ease of understanding and are not intended to limit the actual ratio.

The first embodiment of the present invention is shown in FIG. 2, which is a schematic diagram of a WiMAX wireless network 2. The WiMAX wireless network 2 includes a base station 21 and a mobile station 23. Note that this embodiment only uses one. The base station 21 and a mobile station 23 are exemplified. In other examples, the base station 21 may also perform subsequent bandwidth request procedures for multiple mobile stations at the same time, and the mobile station 23 may be commercially available. Any electronic product with WiMAX wireless network transmission capabilities.

The mobile station 23 is required to perform a network service and requests the base station 21 to request a bandwidth. Accordingly, the mobile station 23 will generate a selected transmission sequence 230 and a fast access message 232, and will select the transmission sequence 230 and quickly save the data. The message 232 is simultaneously transmitted to the base station 21 in a frame. It should be noted that the selected transmission sequence 230 of the embodiment includes a specific bit information (eg, stream identification, bandwidth). The size of the fast access message 232 includes a station identification code corresponding to the mobile station 23. In addition, in other embodiments, the bandwidth size can be placed in the fast memory according to actual needs. The message 232 is not limited to this.

After receiving the selected transmission sequence 230 and the fast access message 232, the base station 21 will know that there is a station to request the bandwidth, and more preferably the station identification code included in the fast access message 232 and the specific transmission sequence 230. Bit information, learn The mobile station 23 wants to request the bandwidth and the size of the bandwidth. Next, the base station 21 will determine whether to allocate the bandwidth to the mobile station 23 according to the state of the network resource of the WiMAX wireless network 1, and if it decides to allocate the frequency. To the mobile station 23, the base station 21 will further generate and transmit a consent signal 210 to the mobile station 23 to inform the mobile station 23 that the requested bandwidth has been configured. After receiving the consent signal 210, the mobile station 23 can perform a data transmission 234 with the base station 21 by obtaining the configured bandwidth.

To explain in more detail how the mobile station 23 communicates with the base station 21 to obtain the bandwidth configuration, please refer to FIG. 3, which is a schematic diagram of the mobile station 23 and the base station 21. As can be seen from FIG. 3, the mobile station 23 includes a storage unit 231, a microprocessor 233, and a transmission/reception interface 235. The microprocessor 233 is electrically connected to the storage unit 231 and the transmission/reception interface 235. 21 includes a memory 211, a microprocessor 213, and a transmission/reception interface 215. The microprocessor 213 is electrically connected to the storage unit 211 and the transmission/reception interface 215. The mobile station 23 and the base station 21 will be described below. The functions of each module are included.

The storage unit 231 of the mobile station 23 is configured to store a transmission information 236 and a sequence generating function 238. The transmission information 236 includes various information required for the mobile station 23 to transmit, such as a stream identification code, a station identification code, and a message. Box information and complex transmission sequences and so on.

When the bandwidth is to be requested from the base station 21, the microprocessor 233 of the mobile station 23 will select a selected transmission sequence 230 from the complex transmission sequence according to the sequence generation function 238 to avoid transmission with other mobile stations during transmission. Collision, the selected transmission sequence 230 can be viewed as a bandwidth request preamble.

In particular, the frame of the WiMAX wireless network may include a plurality of transmission sequences that are orthogonal to each other to avoid interference on the transmission. However, if the mobile station 23 selects the same transmission sequence in the frame in multiple selections. The transmission interference still occurs. To effectively reduce the transmission interference, the sequence of the transmission information 236 is generated as follows: RN = ( a × current_state + p ) mod m

The RN is a number of the selected transmission sequence 230, a is a first preset parameter, and the current_state is information shared by the base station 21 and the mobile station 23, and the information may be the station identification code of the mobile station 23, and the information may be One of the frames, one stream identification code of the mobile station 23, and a combination thereof, p is a second preset parameter, and m is the total number of one of the transmission sequences.

In addition, the storage unit 231 of the mobile station 23 can also store a first sequence correspondence 239, and the microprocessor 233 of the mobile station 23 can select the selected transmission sequence 230 from the complex transmission sequence according to the first sequence correspondence 239. For example, refer to FIG. 4 , which is a schematic diagram of a sequence correspondence relationship. In this embodiment, the first sequence correspondence 239 is used to indicate the correspondence between the stream identification code and the complex transmission sequence. In other embodiments, The first sequence correspondence 239 can be used to indicate the correspondence between other information and the complex transmission sequence.

The FIDN in Fig. 4 represents the stream identification code numbered N, N is from 0 to 23, SM is the transmission sequence numbered M, M is from 0 to 23, and the first sequence is corresponding to 239. FID0 corresponds to S3, FID1 corresponds to S4, FID2 corresponds to S5, ..., FID21 corresponds to S0, FID22 corresponds to S1, and FID23 corresponds to S2, in other words, transmission sequence S0 to transmission sequence S23 are arranged in a cyclic manner. The first sequence corresponds to relationship 239.

In order to reduce the chance of selecting the same transmission sequence, the microprocessor 233 of the mobile station 23 The first sequence correspondence 239 is subjected to a displacement process according to the total number of the transmission sequences (the total number of transmission sequences in the embodiment is 24) and the information shared by the base station 21 and the mobile station 21 to generate a second sequence correspondence. . In detail, when the shared information is 113, the microprocessor 233 will perform 113 division by the total number of transmission sequences and take the rest of the operations, that is, 113 mod 24 is equal to 17, and then the first sequence correspondence 239 is shifted. 17 units of displacement processing to generate a second sequence correspondence, the second sequence correspondence relationship FID0 corresponds to S20, FID1 corresponds to S21, FID2 corresponds to S22, ..., FID21 corresponds to S17, FID22 corresponds to S18 and FID23 Corresponds to S19.

Next, the microprocessor 233 selects the selected transmission sequence from the transmission sequences according to the second sequence correspondence and the stream identification code of the mobile station 23. For example, the stream identification of the mobile station 23 If the code is FID0, the selected transmission sequence will be the transmission sequence of S20. Similarly, if the stream identification code of the mobile station 23 is FID21, the selected transmission sequence will be the transmission sequence of S17.

After the selected transmission sequence 230 is selected, the microprocessor 233 of the mobile station 23 can embed a specific bit information (eg, stream identification, bandwidth, etc.) according to the transmission information 236. In the transmission sequence 230, and based on the transmission information 236, a quick access message 232 is generated. The fast access message 232 includes at least one station identification corresponding to the mobile station 23.

In addition, to ensure that the fast access message 232 is not corrupted during transmission, the microprocessor 233 can perform a Cyclic Redundancy Check (CRC) operation on the fast access message 232 to generate a mobile station CRC. Code and will The mobile station CRC code is embedded in the fast access message 232, so that the base station 21 can verify whether the fast access message 232 is complete according to the mobile station CRC code, and how the base station 21 verifies the integrity of the fast access message 232 according to the mobile station CRC code. Sex will be explained later.

Moreover, after the fast access message 232 containing the mobile station CRC code and the selected transmission sequence 230 are generated, the transmitting/receiving interface 235 is configured to send the selected transmission sequence 230 and the fast access message 232 in a frame. To base station 21.

The storage unit 211 of the base station 21 is configured to store a network resource state 212 of the WiMAX wireless network 1 and the sequence generation function 238. The transmission/reception interface 215 of the base station 21 is configured to receive the selected transmission sequence 230 and quickly save the data. The message 232 is fetched, and the microprocessor 213 of the base station 21 will determine whether the selected transmission sequence 230 can be decoded according to the sequence generation function 238. If not, the microprocessor 213 will transmit a first anti-recognition through the transmission/reception interface 215. (non-acknowledgement) signal to the mobile station 23, the mobile station 23 can regenerate and transmit the fast access message including the mobile station CRC code and the selection of the specific bit information according to the foregoing action according to the foregoing action. The sequence is transmitted to the base station 21.

For example, the microprocessor 21 of the base station 21 can decode the selected transmission sequence 230 according to the sequence generation function 238, and it can be known that one of the stations has specific bit information (for example, stream identification code, bandwidth size, etc.). Wide, need to pay attention, at this time, the base station 21 only knows that there is one station wanting to request the bandwidth, but it is unknown that the mobile station 23 wants to request the bandwidth. Next, the microprocessor 21 of the base station 21 will judge whether the fast access message 232 is decodable. If not, the microprocessor 213 will transmit a second anti-acceptance signal to the mobile station 23 through the transmission/reception interface 215. The 23 mobile stations should respond to the second anti-approval signal. A bandwidth request signal including at least a size of the bandwidth to be requested and a station identification code corresponding to the mobile station 23 is transmitted to the base station 21.

Next, the microprocessor 213 of the base station 21 will determine whether the bandwidth request signal is decodable. If not, the microprocessor 213 will transmit a third anti-acceptance signal to the mobile station 23 through the transmission/reception interface 215. The station 23 is retransmitted for the third counter-approval signal, and at least includes the bandwidth request signal of the station identification code corresponding to the size of the bandwidth to be requested to the base station 21.

For example, the microprocessor 213 of the base station 21 can decode the bandwidth request signal, and can know that the mobile station 23 wants to request the bandwidth according to the station identification code included in the bandwidth request signal, and then, the micro-processing of the base station 21 The device 213 determines, according to the network resource status 212 and the bandwidth to be requested included in the bandwidth request signal, whether there is sufficient network resource configurable to the bandwidth size requested by the mobile station 23. If so, the base station 21 The microprocessor 213 sends a consent signal 210 to the mobile station 23 through the transmission/reception interface 215 to notify the mobile station 23 that the data transmission 234 can be performed with the base station 21 by using the bandwidth.

If the fast access message 232 is decodable, the microprocessor 213 of the base station 21 will know that the mobile station 23 wants to request the bandwidth according to the station identification code included in the quick access message 232. Next, the base station 21 The microprocessor 213 will determine whether there are sufficient network resources configurable to the bandwidth requested by the mobile station 23 according to the network resource status 212 and the bandwidth to be requested. If so, the microprocessor 213 of the base station 21 A consent signal 210 is sent to the mobile station 23 via the transmitting/receiving interface 215 to inform the mobile station 23 that the data transmission 234 can be performed with the base station 21 using the bandwidth.

In addition, after receiving the fast access message 232, the microprocessor 213 of the base station 21 A cyclic redundancy check operation may be performed on the fast access message 232 to generate a base station CRC code, and determine whether the mobile station CRC code and the base station CRC code are the same. If yes, the fast access message 232 is complete. If not, the quick access message 232 is incomplete, and the check action may be determined according to actual needs.

In addition, after generating the mobile station CRC code, the microprocessor 233 of the mobile station 23 can perform a mutual exclusion or (XOR) operation on the mobile station CRC code and the station identification code of the mobile station 23 to generate a mobile station mutual exclusion. Or CRC code, and embed it in the fast access message 232.

If the stream identification code that is taken out is within a reasonable range, it indicates that the fast access message 232 is complete. If the extracted stream identification code is outside the reasonable range, the microprocessor 213 of the base station 21 will take it. The station identification code registered in the base station 21 is repeated until the stream identification code that is taken out is within the reasonable range.
