Since different embodiments of the present invention can be implemented in different types of wireless communication systems (such as purely designed according to different standards or different versions of the same standard), the different components mentioned in the present invention should be understood in a broad sense, and # Use terms that apply to a specific type of system

Generation-specific components should not be construed to mean that embodiments of the present invention are limited to their specific type of system. It should also be noted that although the T ^ 4 embodiment and other embodiments described herein are more important than a system in which one mobile station can move relative to a base station, other embodiments can also be implemented in A system capable of wireless communication between other types of devices. One of the devices may not be _ "Meidi △," a "mobile" device. Therefore, the references in this article and the reference and base stations should be regarded as including any wireless transceivers that can communicate with each other. 96557.doc -11-200524438 In practice, although the specific design of base station 120 and mobile station 14 Everywhere is different, but both are used-through the forward and reverse links: wireless transceivers. Therefore, base station 12 () and mobile station 总体 have the same overall structure. This structure is shown in FIG. 2. All of them are face-to-antenna 226 respectively. The transmitting subsystem 222 and the receiving subsystem 2/24 may be-collectively referred to as-a transceiver subsystem. The transmitting subsystem and the receiving subsystem 224 may access the forward link and / or the reverse link via the antenna 226. Referring to FIG. 2, there is shown a functional block diagram for explaining the basic structural components of a wireless transceiver system according to an embodiment of the present invention. As shown in the figure, the system includes a transmitting subsystem 222 and a receiving subsystem 224.

The transmitting subsystem 222 and the receiving subsystem 224 are also coupled to a processor 228. The processor 228 is configured to control the transmitting subsystem 222 and the receiving subsystem 220. The memory 23 is coupled to the processor 228 to provide work for the processor.

To the processor 228 for processing, and then to the data output terminal 234 'for providing to the user. The data output terminal 234 may include a device such as a speaker as a visual display or an output terminal output to a network device. Those skilled in the art should understand that the structure shown in FIG. 2 is only for illustration. He only knows that other structures can be used. For example, the processor 22 $ 96557.doc -12 · 200524438 can be a general-purpose microprocessor, digital message, inch towel; a processor, and can perform some or all functions of other components in the transceiver, or a transceiver Households: Any other processing required. Therefore, the scope of the patent application scope V described below is not limited to the specific structure described herein. The mobile station 140 is usually not stationary (although ...) Conversely, the mobile station 14. The change in position with respect to the base force mobile station U0 usually causes the wireless link between the mobile station 14 and the base station 120. The channel status changes. The channel status may also be affected by 2 conditions such as atmospheric conditions, the night of other objects between the mobile station and the base station 12 (), and interference from other transmitters. There are changes, so the data rate of the mobile station 140 II D 120 transmission data may also change accordingly. The mobile radio data is beneficial: the change of the material is to provide a sufficient 〇a ^ mbSNR (or the signal to add interference to the interference Information ^, SI is necessary to receive the data with the platform m at an acceptable error rate. The channel-like '% 佳佳' mobile station can be used, the difference is, the more you can use it, The lower the data rate that the channel status must use, the lower the data rate. In some embodiments, the data rate of one or more channels and the corresponding lean format can be referred to as a transmission grid wheel format combination. Each can be separated in the output format The format of the transmission wheel and the transmission method are called the data rate earlier. Two = China, the wireless communication system, and the mobile station I state is that the base station contains special data, "^ Shooting. The first channel among these channels is the first, the first, the second. This data channel can carry various types of data, including 96557.doc 200524438 such as voice data, streaming video or similar data. And its delivery of lower priority data that is not sensitive to delay. In this article, the dedicated data channel can be referred to as the primary data channel, and the second channel is a control channel. The control channel is used to carry the base station as The control information required to correctly decode the data transmitted on the main data channel. The control information may (for example) include pilot channel information, power control information, and data rate information. These different types of information are also It can be characterized as different logical channels in the physical control channel. In the conventional WCD M A system, there is a main data channel and a control channel. Generally, for each message transmitted on the main data channel Each frame has a corresponding frame transmitted on the control channel. The information contained in the control channel frame is used to decode the information in the data channel frame after it is received and decoded by the base station. The control channel frame is It can be transmitted synchronously with the corresponding data channel frame, or before the corresponding data channel frame is transmitted. In this embodiment, in addition to the main data channel and the control channel, a third is also transmitted from the mobile station to the base station. Channel (an enhanced dedicated data channel). In this embodiment, the enhanced data channel is used to transmit data for high-speed services that are not sensitive to delay. In alternative embodiments, other types of data can also be transmitted. The control information for the enhanced data channel needs to be transmitted to the base station so that the base station can decode the data received through the enhanced data channel. However, the control information is not in a control independent of the above control channel. Launch in the channel. Instead, control information for the enhanced data channel is combined with control information from one to the data channel, and then the combined control information is transmitted from the mobile station to the base station on one control channel. The following will explain in detail 96557.doc -14- 200524438 the way to achieve this type of launch. In this embodiment, all = a channel (main dedicated data channel, dedicated control

The control channel and the enhanced dedicated channel (M. Beko channel) both use the same frame format. The format is shown in Figure 3. Figure 3 — A sip of two frames 300 and 310. As shown in the figure, each frame spans ten milliseconds. Each frame is advanced into 15 time slots. As described above, in this embodiment, the control channel is used to transmit control information 'including pilot data, power control data, and data rate information. Referring to FIG. 4, the figure shows a diagram for explaining the structure of the information in each time slot. FIG. 4, "shows a single time slot 400. The time slot 400 contains the introductory information" ο, Power control data 420 and data rate information 43. The time slot 400 is composed of ten bits. Six of these ten bits are used to transmit the pilot data 410, while two bits are used for power control data 42 and two bits are used for data rate information 430. The data rate information is shown in the figure as 1 []? (: 1, or a round format combination indicator. Although TFCI information 43 only contains two bits in each time slot, it can be used to transmit each The frame has more than two bits of TFCI. The reason is that the selected transmission format used by the mobile station to transmit data on the main data channel and the enhanced data channel is updated frame by frame. In other words, ' Each data channel can choose a different transmission format for each subsequent frame. However, the transmission format remains unchanged during the frame. Therefore, all 30 TFCI bits (two bits) in the frame Multiplied by fifteen time slots)-instead of just two TFCI bits in a single time slot, one can be used to transmit the selected TFCI value. 96557.doc -15 · 200524438 Although there is 3 in the frame The single bit is dedicated to body + TFT printing, tearing and pinning. Shooting FCI Bexun to the base station, however, the real bit. This is because the transmission format information will be used in encoding operations to improve the reliability of data transmission. , And: " :: The amount of this element. The following will be This process is summarized. Θθ "shooting material = two pictures: shows a flowchart for _χ data-the process of data encoding in the embodiment of the present invention. Rate information ㈣1} implementation of encoding (block 510). In = line one 1/3 encoding scheme. The encoding operation is composed of the following :: WCDMA communication field public yuan, white capital oblique,… π use the spreading code to cover the original data rate composed of ten data bits Encoding results in 32-bit coded rate information. Since the control data format described provides only 30 bits for data :, some form of rate matching must be performed (block 520). In the embodiment, the 'rate matching function' can only consist of "perforating" the coded data or discarding the last two bits. Therefore, 30 = coded data will be generated from the original data rate information of these ten bits. Data rate information. Then, ^ and other 30-bit coded data rate information can be transmitted from the mobile station to the base station by transmitting the first two bits in the first slot of the frame, Sent in the second slot of the frame The next two bits, and so on, until all 30 bits have been transmitted. In the Baizhi system, 'all ten bits of raw data rate information are available for transmitting data used by the main dedicated data channel. Rate. However, 96557.doc -16-200524438 does not usually need to use ten bits to identify the data rate used for the main data channel. It is usually the case that only a relatively small number of possible data rates are used for the data channel. For example, there may be only four or eight possible data rates available for the actual data rate of the main dedicated channel. If there are only four possible data rates, only two bits are required to identify the Which of the four possible data rates is used? ^ K selects the lean data rate. Similarly, if there are only eight (2) or 16 (24) possible data rates, then only three or four bits are required to identify the selected rate. Therefore, in these examples, six to eight of the ten bits that are available for transmitting data rate information are unpaid. In this embodiment, the bits that are not used to identify the data rate of the main data channel are used to identify the data rate of the enhanced data channel. In the above example, since four bits are used to transmit the data rate of the main data channel, six of the ten bit% s in the waiting list can be used to identify the data rate of the enhanced data channel. These six bits can be used to identify which data rate is selected from the 64 (26) possible rates. Therefore, in this implementation,-the main data channel = channel to choose the appropriate data rate, and set the data rate indicator of these values in the ten available bits, and then if these bits 〇3 The data rate information of the main channel is processed in the same way as the ten-bit 7L s base station receives the control data frame, and extracts the data corresponding to the main data channel and enhanced data communication; S2 rate information 'and use this data rate information to decode the corresponding lean channel. 96557.doc 200524438 The method used in this example is shown in FIG. 6. FIG. 6 is a flowchart illustrating a process of transmitting control information for two data channels through a single control channel. The method shown in the figure includes a first part on the left side of the figure and a second part on the right side of the figure. This first part generally corresponds to the part of the method performed by the mobile station. This second part generally corresponds to the part of the method performed by the base station. It should be noted that in addition to the entire method shown in the figure, the first part and the second part of the method may themselves be considered as alternative embodiments. As shown in FIG. 6, the method first selects data rate information for the first, primary dedicated data channel (block 605), and selects data rate information for the second, enhanced dedicated data channel (block 61). . The data rate can be selected for each data channel in any suitable manner, such as using methods known to them in wireless communication technology. When ^ -data rate is selected for each channel, the corresponding data rate symbol is also selected. As mentioned above, if -data rate is selected from 2% of possible data rates, the selection rate can be expressed by bit values. The data rate information (e.g., data rate indicator) for the two data channels is then combined (block 615). In the embodiment, only one of the two data rate indicators is added to the other to combine them. So 'if the data rate indicator of the first data channel consists of-four-bit values, and the data rate indicator of the second data channel consists of one six-bit value ^', then the ten data rate bits The first four bits in the middle may include the first data rate inconsistency, and the last six of the ten f data rate bits may each include a §! Second data rate indicator. In an alternative embodiment, the data rate indicators of the two data channels 96557.doc 200524438 may be combined (multiplexed) in a different manner. After combining the data rate information of the two data channels, the combined information is coded (block 620). In one embodiment, the ten bits of the combined data rate information are the ten bits of the data rate information with the main data channel.

Bits are encoded in the same way as usual. In the above embodiment, the encoding operation is composed of: covering the data bits with a spreading code (such as using a 1/3 encoding scheme), and then performing rate matching (such as puncturing) on the data to generate a control signal The number of bits transmitted in the box (for example 30). The encoded data rate information is then transmitted in a frame on the control channel (block 625). In the above embodiment, 'this consists of the following operations: two bits of the encoded data rate information are transmitted in each time slot of the control frame. Therefore, the first two bits of the encoded data rate information are transmitted in time slot 0, the next two bits are transmitted in time slot 1, and so on.

After the control data frame is transmitted by the mobile station, it is transmitted to the base station via the dedicated control channel and received by the base station (block 63). The received control information frame is then decoded (block 635). In _implementation, the control is decoded in the same way as if the control data of the -data channel is included. In the other way, the control data can also be used to decode the control data. After the control data is decoded, the base The station can get these ten bits of control information. Therefore, the base station will extract the data rate information for each data channel in the first and second channels (block _. If the action was originally only by appending the middle-data rate indicator to another 96557. doc -19- 200524438 rate indicator to combine these data rate indicators, the base station will extract these ten bits into data rate indicators for the first and second data channels to extract These indicators. If the mobile station multiplexes the data rate indicators together in a more complex way, the base station uses a corresponding demultiplexing method to extract these indicators. When self-control information After the data rate indicators for the first and second data channels are extracted from the base station, the base station uses these data rate indicators to determine the data rate used when transmitting the first and second data channels, and then uses the respective data Rate information to decode the first data channel and the second data channel (blocks 645, 650). It should be noted that many changes can also be made in the embodiment described above, which does not depart from the patent application below. The scope of the present invention is described in detail below. For example, 'Although the foregoing embodiment involves combining data rate information for two data channels on a single control channel, in other embodiments, it is also possible to combine The data rate information for two or more data channels can be combined. The data rate information for n data channels can also be combined in m control channels, where η is greater than m. In another embodiment, the data rate information can be combined. Information other than data rate information (such as frame formatting information) for different data channels is combined on one or more control channels. In another variation, bits available for transmitting data rate information can be used Assigned to different data channels differently than described above. For example, instead of assigning four bits to one channel and six bits to another channel ', two / eight bits can be assigned , Three / seven bits, five / five bits, etc. Alternative frame and / or time slot formats can also be used to make 96557.doc -20- 200524438 available for transmitting data rate information More bits At or less than ten. Higher-level signaling can be used to change the bit allocation between these different data rate indicators from time to time.
