SYSTEMS AND METHODS FOR COMMUNICATING CONTROL DATA

USING MULTIPLE PARTITION FORMATS

FIELD

The present invention generally relates to communication systems and, more particularly, to systems and methods for providing systems and methods for communicating control information by transmitting control information on partitions using at least two different partition formats.

BACKGROUND

A wireless telecommunications system can be used to allow information to be communicated between a mobile device and a base station, between a mobile device and an information server, between mobile devices, and so on. The information communicated between the various devices can include audio information (for example, voice), high-speed data, control information and various other types of data.

An exemplary telecommunications system includes a base station controller, one or more base stations, and one or more mobile stations. Each of the base stations is coupled to the base station controller by a network that is normally referred to as the return transport and the physical communication return transport between the base station controller and the base stations. Each of the mobile stations is coupled to one of the base stations. The communication links between mobile stations and base stations comprise wireless links.

laugh like the net in channel in (backhaul). The net in channel in understands typically links in

2/26

The wireless communication link between each mobile station and the base station with which it communicates includes a set of channels for communicating data from the base station to the mobile station, as well as a set of channels for communicating data from the mobile station to the base station. The first set of channels (from the base station to the mobile station) is referred to as a direct link. The second set of channels (from the mobile station to the base station) is referred to as a reverse link.

The channels of both the direct link and the reverse link are configured to carry various types of information. For example, some of the channels carry data, while others carry control information. In one embodiment, the reverse link includes a primary dedicated data channel and a corresponding dedicated control channel. The control channel is configured to carry the information necessary to decode the primary dedicated data channel, such as an indication of the data rate at which data is transmitted on the data channel.

It may be desirable to add another data channel to that system. As with the primary dedicated data channel, it will be necessary to transmit the control information to the additional data channel in order to allow the base station to decode the data that is transmitted on the additional data channel. Conventionally, this control information would be transmitted on an additional control channel corresponding to the additional data channel. This solution, however, is disadvantageous since it requires the use of resources (for example, additional processing, additional spreading codes, etc.) to support the additional control channel. It would therefore be desirable to provide improved systems and methods for communicating

3/26 control information required for the additional data channel.

DETAILED DESCRIPTION

One or more embodiments of the invention are described below. It should be noted that these and any other modalities described below are exemplary and are intended to be illustrative of the invention and not limiting.

As described here, various embodiments of the invention comprise systems and methods for communicating control information by transmitting control information on partitions using at least two different partition formats. In one embodiment, a method is implemented in a wireless communication system. The method

7/26 includes providing at least two different partition formats, formatting control data on the partitions of a control board according to at least two different partition formats, transmitting the control board from a mobile station to a station base via a control channel, receive the control board, extract the control data from the control board according to at least two different partition formats, decode the extracted control data and decode the received data via one or more data channels using the decoded control data. In one embodiment, the method is used to allow additional TFCI data corresponding to two different data channels to be transmitted on a single control channel.

One embodiment of the invention is implemented in a wireless telecommunications system that is designed according to a WCDMA (multiple access code division in broadband) standard. Therefore, it is useful to describe the basic structure and operation of such a system in order to assist in understanding the invention. It should be noted that, while the description below basically focuses on a system that follows this pattern, alternative modalities can be implemented in systems that follow other patterns as well.

With reference to figure 1, a diagram illustrating the structure of a wireless telecommunications system according to a modality is shown. System 100 includes a base station controller 110, a base station 120 that is coupled to base station controller 110 via a return transport channel network 130, and a mobile station 140. System 100 can include base stations

8/26 additional and mobile stations that, for clarity, are not shown in the figures.

The terminology used to refer to the components of the system may differ from one modality to another. For example, base station controller 110 can be referred to as a radio network controller (RNC), base station 120 can be referred to as a Node B and mobile station 140 can be referred to as user equipment (UE). Since several modalities of the invention can be implemented in different types of wireless communication systems (for example, systems designed according to different standards or different versions of the same standard), references to different components of the systems must be interpreted broadly , and references to particular components using terminology applicable to a particular type of system should not be considered to imply that the modalities of the invention are limited to that particular type of system.

It should also be noted that, while the description of this and other modalities focuses on a system in which a mobile station can move in relation to a base station, other modalities can be implemented in systems that allow wireless communication between types alternative devices. It is not necessary for one device to be a base station, nor is it necessary for the other device to be mobile. References here to mobile stations and base stations should therefore be considered to include any wireless transceiver devices that are in communication with each other.

While, in practice, specific designs for base station 120 and mobile station 140 may vary significantly

9/26 significant, each serves as a wireless transceiver to communicate through forward and reverse links. Base station 120 and mobile station 140 therefore have the same general structure. This structure is illustrated in the figure

2.

With reference to figure 2, a functional block diagram illustrating the basic structural components of a wireless transceiver system according to a modality is shown. As shown in that figure, the system comprises a transmission subsystem 222 and a receiving subsystem 224, each of which is coupled to an antenna 226. The transmission subsystem 222 and the receiving subsystem 224 can be collectively referred to as a transceiver subsystem. . The transmission subsystem 222 and the receiving subsystem 224 access the direct and / or reverse link through antenna 226.

transmit subsystem 222 and receive subsystem 224 are also coupled to processor 228, which is configured to control transmit and receive subsystems 222 and 224. Memory 230 is coupled to processor 228 to provide a working space and local storage for the processor. Processor 228 and memory 230 can be collectively referred to as a processing subsystem. A data source 232 is coupled to processor 228 to provide data for transmission through the system. The data source 232 can, for example, comprise a microphone or an input from a network processor device 228. The data is processed by and then sent to the transmission subsystem 222, which transmits the data via antenna 226. The data received by the receiving subsystem 224 through antenna 226 is routed to processor 228 for processing and then to the output of data 234 for

10/26 presentation to a user. Data output 234 can comprise such devices as a speaker, a visual display or an output to a network device.

Those skilled in the art of the invention will appreciate that the structure shown in figure 2 is illustrative and that other modalities may use alternative configurations. For example, processor 228 which may be a general purpose microprocessor, digital signal processor (DSP) or special purpose processor may perform some or all of the functions of other components of the transceiver, or any other processing required by the transceiver. The scope of the claims presented below should therefore not be limited to the particular configurations described here.

Mobile station 140 is not typically stationary (although in some cases it may be). Mobile station 140 may instead move with respect to base station 120. The modified position of mobile station 140 typically causes channel conditions for the wireless link between mobile station 140 and base station 120 vary. Channel conditions can also be affected by other factors, such as atmospheric conditions, movement of other objects between mobile station 140 and base station 120, interference from other transmitters, and so on.

Due to changes in channel conditions for the wireless communication link, there may be changes in the data rate at which mobile station 140 transmits data to base station 120. These changes in data rates used by mobile station 140 to transmit the data is necessary to provide a signal-to-noise ratio (SNR) (or signal / interference-to-noise ratio, SINR) high enough that base station 120 will receive the data with

11/26 an acceptable error rate. The better the conditions of

channel, the higher the data rate what can be used by the mobile station. The worse at conditions channel, the lower the rate in data that must be used by mobile station. The rate in data and O Format of data corresponding to one or more channels can, in some

modalities, be referred to as a transport format (TF) or combination of transport format (TFC). For the sake of clarity, individual transport formats in addition to transport format combinations can be referred to below simply as data rates.

In one embodiment, the mobile station in the wireless telecommunications system is configured to transmit information to the base station on three channels. The first of these channels is a dedicated data channel. This data channel can carry various types of data, including such high priority data as voice data, streaming video or the like, and lower priority data, the delivery of which is not sensitive to delay. This dedicated data channel can be referred to here as the primary data channel. The second of the channels is a control channel. The control channel carries the control information that is needed by the base station in order to properly decode the data transmitted on the primary data channel. This control information can, for example, include pilot channel information, power control information and data rate information. These different types of information can also be characterized as different logical channels within the physical control channel.

The primary data channel and the control channel are found in conventional WCDMA systems.

12/26

Typically, for each frame that is transmitted on the primary data channel, there is a corresponding frame that is transmitted on the control channel. The information contained in the control channel frame is received by the base station, decoded, and then used to decode the information in the data channel frame. The control channel frame can be transmitted synchronously with the corresponding data channel frame, or it can be transmitted before the transmission of the corresponding data channel frame.

In the present embodiment, in addition to the primary data channel and the control channel, a third channel (an improved dedicated data channel) is transmitted from the mobile station to the base station. The improved data channel is used in this mode to transmit data for high-speed and non-delay sensitive services. In alternative modalities, other types of data can be transmitted. As long as it is necessary to transmit control information through the data channel

improved to station shape base what the station base be likely to decode the data received via the channel in Dice improved, these information in control not are

transmitted on a control channel that is separate from the control channel described above. Instead, the control information for the enhanced data channel is combined with the control information for the primary data channel, and the combined control information is transmitted from the mobile station to the base station on the control channel. The way in which this is done is described in detail below.

In this modality, all three channels (the primary dedicated data channel, the dedicated control channel and the improved dedicated data channel) use the

13/26 same frame format. This format is illustrated in figure 3. Figure 3 shows two frames 300 and 310. As shown in this figure, each frame spans ten milliseconds. Each frame is further divided into 15 partitions.

As mentioned above, the control channel is used in this modality to transmit control information including pilot data, power control data and data rate information. With reference to figure 4, a diagram illustrating the structure of this information within each partition is shown. Figure 4 shows a single partition 400. Contained within partition 400 are pilot data 410, power control data 420 and data rate information 430. Partition 400 consists of ten data bits. Six of these ten bits are used to drive pilot data 410, while two bits are used as power control data 420 and two bits are used for data rate information 430. The data rate information is illustrated in the figure as TFCI, or transport format combination indicator. The allocation of the partition bits as shown in figure 4 is referred to as the partition format. The same partition format is conventionally used for each partition.

While the TFCI 430 information comprises only two bits of the partition format, 30 bits are available to communicate the TFCI value for each frame as the selected transport formats used by the mobile station to transmit data on the primary and enhanced data channels are updated accordingly. frame by frame. In other words, while each data channel can select a different transport format for each successive frame, the transport format remains unchanged during the frame. That way, all 30 bits

14/26

TFCI in the frame (two bits times fifteen partitions), instead of just two TFCI bits in a single partition, are available to communicate the selected TFCI value.

It should be noted that the 30 bits of TFCI information transmitted in a frame are encoded data, rather than raw TFCI data. Since the encryption process used in a wireless communication system such as the system of the present embodiment typically increases the number of data bits, less than 30 bits of raw transport format information are communicated. The encoding (and the corresponding increased number of bits) should increase the reliability with which the data is communicated.

Referring to figure 5, a flow chart is shown illustrating the process by which data rate information is encoded according to an embodiment. In this figure, the data rate information (TFCI) is encoded (block 510). In this case, the encoder implements a 1/3 encoding scheme. Coding consists of covering the original data rate information with spreading codes in a way that is well known to those skilled in the art in the field of WCDMA communications. The encoding of the original data rate information, which consists of ten data bits, results in 32 bits of encoded rate information data. Since the partition format for the control channel, as described above with respect to figure 4, provides only 30 bits for data rate information, some form of rate matching must be performed (block 520). In one embodiment, the rate matching function may simply consist of puncturing encrypted data or deleting the last two bits.

In this way, 30 bits of encoded data rate information are generated from ten bits of the

15/26 original data rate information. The 30 bits of encoded data rate information can then be transmitted from the mobile station to the base station by transmitting the first two bits in the first frame partition, the next two bits in the second frame partition, and so on, until all 30 bits have been transmitted.

In a conventional system, all ten bits of the original data rate information are available for use in conducting the data rate used by the primary dedicated data channel. Typically, however, ten bits do not require identifying the data rate for the primary data channel. It is usually the case that there is a relatively small number of possible data rates for that data channel. For example, there can be only four, eight or 16 possible data rates from which the actual data rate can be selected. If there are only four possible data rates, only two bits need to identify which of the four (2 ² ) possible data rates has been selected. Similarly, if there are only eight (2 ³ ) or 16 (2 ⁴ ) possible data rates, only three or four bits, respectively, need to identify the selected rate. Consequently, in these examples, six to eight bits of the ten bits that are available to carry data rate information are not used.

In the present embodiment, bits that are not used to identify the data rate for the primary data channel are, instead, used to identify the data rate of the improved data channel. In the example above, in which four bits are used to drive the data rate of the primary data channel, six of the ten bits are available for use in identifying the data rate of the enhanced data channel. Those six bits

16/26 can serve to identify which data rate is selected from among 64 (2 ⁶⁾ possible rates.

The process of allocating a portion of the ten TFCI bits to one data channel and the rest of the TFCI bits to another data channel is suitable if only ten bits are needed to transmit the data rate information to both data channels. If more than ten bits are needed, however, this method is not suitable. Additional bits must, in some way, be made available to transmit the data rate information.

At first, it may seem possible to simply allocate more than two bits in the partition format for data rate information (TFCI). For example, it may appear that one of the bits allocated for the pilot data (410) or one of the bits allocated for the power control data (420) can simply be allocated to the data rate information (430). This can be problematic, however, since reducing the number of bits allocated for pilot data (410) or power control data (420) can degrade system performance.

The number of bits that are conventionally used for pilot data and power control data were determined through experiments and theoretical study. Channel estimation (which is performed using pilot data 410) and power control (which is performed using power control data 420) are performed on each partition, rather than on each frame. It is therefore necessary to provide sufficient data on each partition to allow for proper channel estimation and power control. It was determined through experiments and theoretical study that for typical conditions, six bits are required for pilot data and

17/26 two bits are required for power control data. If only five bits of pilot data are provided on each partition, the channel estimation performance for the system is degraded. Likewise, if only one bit of power control data is provided in each partition, the power control performance in the system is degraded.

In the present modality, it is assumed that three bits from each partition are necessary to carry the data rate information to the dedicated data channels. This corresponds to a total of 45 encoded bits of data rate information (and 15 bits of raw data rate information if a 1/3 encoding is being used). It is also assumed that the performance of the system would be degraded by the transmission of only five bits of pilot data in each partition or the transmission of just one bit of power control data in each partition. The present system, therefore, changes the partition format periodically to alternately reduce the number of pilot data bits or the number of power control data bits so that three TFCI bits can be included in each partition.

An embodiment of this alternate partition format is illustrated in figure 6. As shown in the figure, a first partition 610 includes six pilot data bits, one power control data bit and three TFCI data bits. A second partition 620 includes five bits of pilot data, two bits of power control data and three bits of TFCI data. A third partition 630 is identical to partition 610 and includes six pilot data bits, one power control data bit and three TFCI data bits. Thus, partition 630 therefore begins by repeating the pattern of partitions 610 and 620. This pattern is

18/26 continued through partitions 640 and 650 and the rest of the partitions in the frame.

Thus, in this mode, six bits of pilot data are transmitted in one partition, then five bits of pilot data are transmitted in the next partition, then six bits are transmitted in the next partition, and so on. While the system channel estimation performance corresponding to partitions in which only five bits of pilot data is transmitted is degraded compared to normal performance (using six bits of pilot data), this degraded performance is experienced in only one partition yes another not. It has been determined that when these periods of degraded performance are interspersed with periods of normal performance (corresponding to the partitions in which six bits of pilot data are transmitted), the total channel estimation performance is only slightly degraded and in fact corresponds to levels acceptable performance. Similarly, although the transmission of just one power control bit in each partition does not provide adequate power control performance, switching between one and two power control bits in successive partitions does not appear to substantially degrade power control. power.

Since each frame includes fifteen partitions, the two-partition pattern in Figure 6 cannot be repeated an entire number of times. As a result, the number of partitions identical to partition 610 will not be equal to the number of partitions identical to partition 620. In one embodiment, the partitions in each frame are identical. That is, the number of partitions identical to partition 610 and the number of partitions identical to partition 620 will be the same in each frame. In an alternative modality, staff

Successive 19/26 may not be identical, but may instead continue the repeat pattern of partitions 610 and 620. Thus, a frame can have eight partitions identical to partition 610 and seven partitions identical to partition 620, while The next frame can have seven partitions identical to partition 610 and eight partitions identical to partition 620.

In another mode, it is assumed that transmitting 40 bits of encoded information, instead of 45 bits. Since 40 is not evenly divisible by fifteen partitions of the control board, the number of bits allocated for the data rate information in each partition changes from one partition to another data rate.

With reference to figure 7, the partition formats of successive partitions in this alternative mode are shown. A first partition 710 in this mode includes six bits of pilot data, one bit of power control data and three bits of TFCI data. A second partition 720 includes five bits of pilot data, two bits of power control data and three bits of TFCI data. A third partition 730 includes six bits of pilot data, two bits of power control data and two bits of TFCI data. This pattern is repeated starting with the fourth and fifth partitions 740 and 750.

In the modality of figure 7, the channel estimation performance of the system is improved with respect to the partition formats of figure 6 since, instead of one partition yes and another not being reduced by a bit, only each third partition has a number reduced bits. More pilot data is therefore communicated to the base station. The same is true of the system's power control performance. 0 number of bits

20/26 power control is reduced for each third partition instead of every second partition, so that more power control data is communicated to the base station. The performance of the system is therefore improved with respect to both channel estimation and power control.

As noted above, in one embodiment, the data rate information that is transmitted on the control boards identifies the data rates for two different data channels. In this mode, the mobile station selects data rates suitable for the two data channels, combines data rate indicators corresponding to those data rates, and then processes the combined data and transmits the data. Control data is transmitted using multiple partition formats. When the control data frame is received by the base station, the information in the multiple partition formats is decoded and the data rate information corresponding to each of the primary and enhanced data channels is extracted and used in decoding the data channels. corresponding data.

The methodology used in the present modality is illustrated in figure 8. Figure 8 is a flowchart illustrating the process of communicating control information to two data channels through a single control channel using multiple partition formats. 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. The first part generally corresponds to the part of the method that is performed by a mobile station. The second part generally corresponds to the part of the method that is performed by a base station. It should be noted that, in addition to the entire method

21/26 shown in the figure, the first and second parts of the method can, by themselves, be considered alternative modalities.

As shown in figure 8, the method begins with the selection of data rate information for the first and second data channels (block 805). The data rate selection for each of the data channels can be carried out in any suitable way, such as the methods that are known in the wireless telecommunications technique. When a data rate for each channel has been selected, a corresponding data rate indicator is also selected. As noted above, if a data rate is selected from 2 ⁿ possible data rates, the selected rate can be represented by a value of n bit.

The data rate information (for example, data rate indicators) for the two data channels is then combined (block 810). In one embodiment, the two data rate indicators are combined simply by attaching each other. Thus, if the data rate indicator for the first data channel consists of a nine-bit value and the data rate indicator for the second data channel consists of a six-bit value, the first nine of the fifteen bits data rate may contain the first data rate indicator, while the last six of the data rate bits may contain the second data rate indicator. In the alternative modalities, the data rate indicators for the two data channels can be combined (multiplexed) differently.

After the data rate information for the two channels is combined, the combined information is encoded (block 815). In one embodiment, the fifteen bits of combined data rate information are

22/26 encoded in the same way as the data rate information for the primary data channel is conventionally encoded. In the mode described above, encoding consists of using a 1/3 encoding scheme and then matching the rate (for example, punching) of the data to generate the number of bits (for example, 45) that can be transmitted in the frame. control.

The encoded data rate information is then formatted in multiple partition formats (block 820). In one embodiment, each partition contains three bits of data rate information and variable numbers of power and pilot control data. The variable formatted data is then transmitted in a frame on the control channel (block 825), with the first three bits of the encoded data rate information being transmitted on partition 0, the next three bits transmitted on partition 1, and so on. onwards.

After the control data frame is transmitted by the mobile station, it is communicated to, and received by, the base station via the dedicated control channel (block 830). Although the partition format of the control information varies from one partition to another, the partition formats that are used are known to the base station, either because that information is predetermined or because the information is communicated through upper layer signaling. The received control information frame is then decoded (block 835). In one embodiment, the decoding of control information is performed in the same way as if only control data for a data channel were included. In other modalities, the decoding of the control information can be carried out in other ways.

23/26

When the control data is decoded, the fifteen bits of control information will be available to the base station. The base station, therefore, extracts the data rate information for each of the first and second data channels (block 840). If the mobile station is combined with the data rate indicators simply by attaching them to each other, the base station extracts the indicators by parsing the bits in the respective data rate indicators for the first and second data channels. If the mobile station multiplexes the data rate indicators in a more complex way, a corresponding demultiplexing method is used by the base station to extract the indicators.

After the data rate indicators for the first and second channels have been extracted from the control information, the base station uses these data rate indicators to determine the data rates at which the first and second data channels are transmitted, then, the codes of the first data channel and the second data channel using the respective data rate information (blocks 845 and 850).

It should be noted that the modalities described above involve the transmission of combined control data since a single data channel typically does not require more than ten bits which can be communicated using the conventional partition format shown in figure 4. However , in some modalities, it may be necessary, when there are more than ten bits of TFCI information, to be communicated by a single channel, in which case multiple described partition formats can be used. It should be noted that multiple partition formats can also be useful in some ways for reasons other than communicating rate information.

24/26 additional data. Other variations in the above modalities are also possible.

Although not discussed in detail above, it should be noted that the functionality described above can be implemented on the mobile stations and on the base stations described above by providing suitable programs that run on the respective processing subsystems of those devices. These program instructions are typically incorporated into a storage medium that is readable by the respective processing subsystems.
