Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless access system, and more particularly to a method for transmitting or receiving data using a super-frame structure, which can reduce power loss and maintain a burden. [Prior Art]

A typical wireless communication system provides one or more shared resources to multiple users. For example, wireless communication systems may employ various multiple access schemes such as code division multiple access (CDMA), time division multiple access (TDMA), and frequency division multiple access (FDMA). In general, the base station schedules radio resources. The radio resources are uplink resources in the uplink and downlink resources in the downlink. In the downlink, the base station notifies the user equipment of the downlink resources assigned to the data stream, and the user equipment receives the data stream via the downlink resources. In the uplink, the base station notifies the user equipment of an uplink resource assigned to the data stream, and the user equipment receives the data stream via the uplink resource. The amount of assigned radio resources varies depending on the stream traffic to be transmitted, the channel status, or the quality of service (QoS). The more data stream traffic, the more non-line resources that must be assigned. However, due to the limited amount of wireless resources, it is necessary to efficiently assign radio resources. Information about the assignment of radio resources must be repeatedly provided to the user equipment because the user equipment must be aware of the information about radio resource assignments in the uplink or downlink to receive the data stream. The information about the wireless resource refers to a control signal transmitted to the user equipment via a dedicated control channel or a normal control channel. The exclusive control channel refers to the control channel for a particular user device, while the normal control channel refers to the control channel for all user devices in the application area.

Excessive map headers increase the system maintenance burden when transferring data via a normal control channel or a dedicated control channel in each frame. Therefore, it is necessary to increase the transmission period of the normal control channel. In addition, since the user equipment that does not need to transmit and receive data must also decode the data in the exclusive control channel and all redundant data areas, the user equipment also suffers power loss. Systems with long transmit frames add more feedback delays than systems with short transmit frames. This feedback delay can result in degradation of link suitability performance. [Disclosure] [Technical Problem] An object of the present invention devised to solve the problem is to provide a super-frame structure capable of reducing a MAP header of a transmission frame and reducing communication power. Another object of the present invention devised to solve the problem is to provide a method for transmitting data using the super-text framework. Yet another object of the present invention devised to solve the problem is to provide a method of receiving hyperframe data from a user device. The technical solution achieves the goal of the invention by providing a super-information framework including a super-frame header. The super-text framework includes: one including user data.

At least one sub-frame may be disposed between the data area control areas, and the feedback channel may be within a prescribed number of frames of the dedicated control area before being in the control area. The normal control area may include a resource area for the start position of the sub-frame to start in the sub-frame. The normal control area may include the starting position being 0 or greater. In addition, the normal control area may include information on the number of sub-frames that are started from the starting position. The number of consecutive subframes may be one or greater.

And including a dedicated control area containing information area assignment information, the designation of the poor information refers to the source allocation of the tributary area, and the super box. The dedicated control area can be arranged to one of a plurality of locations, with the exception of one of the subframes of the superframe header. The domain, the channel is the channel source, and the domain is associated with the dedicated sub-information, the BCH. Before the start of i, 1 ' 2, including Super: Generate data area, the transfer should be at least 8 200922182 The exclusive control area can be located before the superframe header and include information for the location of the exclusive control area The available resources between the superframe locations are assigned to the data area. The exclusive control area of the new zone (eg IEEE 802.1 6m) can be arranged in at least one subframe of several subframes, except for the old legacy areas of IEEE 802.16e.

The dedicated control area can be arranged in a different subframe depending on the frequency band. The data area assignment information may include at least one of the following two types of information: the position of the sub-frame at the beginning of the data area; and the number of sub-frames belonging to the data area. The hyperframe header may further include a normal control area for transmitting information about the sub-frames managed by the dedicated control area. The super frame header may further include a normal control area, which includes information about the location of the feedback channel, the feedback channel is used to transmit channel information of the downlink, and the feedback channel may be located before the dedicated control area, and the dedicated control area is The specified number of sub-frames.

Advantageous Effects According to an exemplary embodiment of the present invention, a user equipment that does not need to transmit and receive data uses a super-frame structure to decode data area assignment information by using data area information indicated by a dedicated control area, thereby powering Minimize consumption, reduce feedback delays, and reduce system maintenance burden. [Embodiment] Exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. The exemplified embodiments of the present invention are intended to be illustrative of the specific embodiments of the invention. Figure 1 is a block diagram showing a wireless communication system. Wireless communication systems are widely used to provide a variety of communication services, such as voice and packet data. The wireless communication system includes a User Equipment (UE) 10 and a Base Station (B S) 20. Each user device 10 can be fixed or mobile. Other terms may be used to refer to user equipment 1 , such as a mobile station (M S ), a 10 200922182 user terminal (UT), a subscriber station (SS), or a wireless device. Base station 20 is a fixed station that communicates with user equipment 10 and may be referred to by other terms, such as a Node B (B-B), a base transceiver system (BTS), or an access point. One or more units may be present within the base station 20.

In the following, downlink refers to communication from base station 20 to user equipment 10, and uplink refers to communication from user equipment 10 to base station 20. In the downlink, the transmitter can be part of the base station 20 and the data receiver can be part of the user equipment 10. In the uplink, the transmitter can be part of the user equipment 10 and the data receiver can be part of the user equipment 20. Multiple access schemes for downlink transmission and uplink transmission may differ from each other. For example, an orthogonal frequency division multiple access (OFDMA) scheme can be used for downlink transmission, and a single carrier frequency division multiple access (SC-FDMA) scheme can be used for uplink transmission. Multiple access schemes applied to wireless communication systems are not limited. For example, CDMA, TDMA, FDMA, SC-FDMA 'OFDMA or other conventional modulation techniques can be used depending on the multiple access scheme. The modulation scheme described above demodulates signals received from a plurality of users of the communication system to increase the capacity of the communication system. Figure 2 illustrates an example of a frame structure. The frame structure of Figure 2 can be applied to a frequency division duplex (FDD) scheme and a time division duplex (TDD) scheme. The frame structure includes a common control area, a dedicated control area, and a data area. These control areas are only used to transmit control signals, and are usually assigned a number of 11 200922182 control channels. The data area is used to transfer data and is usually assigned a data channel. The control channel transmits a control signal that transmits the user data. The control channel and the data channel can be constructed by a frame. The control signal indicates a signal that is not a user profile, including an acknowledgment (ACK) / negative acknowledgment (NACK) signal, a channel quality indicator (CQI), a precoding matrix index (PMI), a rank indicator (RI), and a scheduling request signal. and many more.

Unlike the control area, user data and control signals can be transmitted in the data area. That is, when the user transmits only the control signal, the control channel can be assigned so that the control signal can be transmitted via the control channel. When the user equipment transmits data and control signals, a data area can be assigned to transmit data and control signals. However, when there are a large number of control signals to be transmitted, or when the control signals are not suitable for transmission via the control channel, even if only the control signals are transmitted, a wireless resource can be assigned to the data area to transmit the control signals. The normal control area is an area in which control information transmitted to all user equipments is carried, such as system parameters, preamble, location of the ranging area, and the like. A dedicated control area is an area in which control information is transmitted to a particular user device or to a plurality of specific user devices. For example, the data area assignment information (or MAP information) of the resources required for each user equipment to transmit and receive data is the control information of the exclusive control area. The ACK/NACK channel, CQI channel, etc. can be transmitted via the normal control area, via the dedicated control area, or can be transmitted via both the normal control area and the dedicated control area. Figure 3 illustrates another example of a frame structure. Frame system is a physical regulation 12 200922182

To illustrate the sequence of data that can be used in the fixed time period of the OFDMA specification. For convenience of explanation, the manner of the frame used in the TDD system is shown, but is used in the frame structure used in the FDD system. This frame can be a frame. The frame includes a downlink frame and an uplink channel

The message box. TDD shares the same frequency in both uplink and downlink transmissions, '一_七_ 仓仓 Sjt

And downlink transmissions occur at different time intervals. The downlink frame temporarily leads the uplink frame. The downlink (DL) frame includes a frame control header (FCH), a downlink MAP (DL-mAP), an uplink key MAp (UL-MAP), and a DL cluster area. The uplink (UL) frame includes several cluster areas. The guard time for distinguishing between the uplink frame and the downlink frame is inserted into the middle portion of the frame (ie, between the downlink frame and the uplink frame) And is inserted after the frame (ie, after the uplink frame). The transmit/receive transition gap (ττ^) is the gap between the DL cluster and the subsequent UL cluster. The receive/transmit transition gap (RTG) is the gap between the UL cluster and the subsequent UL cluster. The foregoing is used for initial synchronization, cell search, frequency offset, and channel estimation between the base station and the user equipment. The FCH includes information about the DL-MAP message length and the DL-MAP coding scheme. dL-ΜΑΡ is the area where the DL-MAP message is transmitted. The DL-MAP message defines access to the downlink channel. The DL-ΜΑΡ message includes the number of configuration changes for the Downlink Channel Descriptor (DCD) and the Base Station Identifier (ID). The downlink channel descriptor description is applied to the current link cluster profile below the MAP. Downlink Cluster 13 200922182 The profile indicates the characteristics of the Link Physical Channel. The downlink channel descriptor is periodically transmitted by the base station via the DCD message.

The UL-MAP is an area that transmits UL-MAP messages. The UL-MAP message defines access to the upstream keyway. The UL-MAP message includes a configuration change count for the Uplink Path Channel Descriptor (UCD) and a valid start time for the uplink assignment as defined by the UL-MAP. U C D describes the uplink cluster profile. The uplink cluster profile indicates characteristics of the uplink physical channel. The UCD is periodically transmitted by the base station via UCD messages. One portion of the uplink channel frame includes a fast feedback area. The fast feedback area is assigned for fast uplink transmissions faster than the usual uplink data, and CQI or ACK/NACK signals can be carried over the area. The fast feedback area can be located in any area of the link frame and is not limited to the position or size shown in FIG. Figure 4A illustrates an example of a super-framework. The super frame consists of 10 sub-frames, each of which includes 2 time slots. A time slot includes a plurality of OFDM symbols in a time region and at least one subcarrier within the frequency region. A time slot is used to assign units of radio resources within the time zone. For example, a time slot can include 6 or 7 OFDM symbols. The super-frame structure shown is only an example. The number of sub-frames included in the super-frame, the number of time slots included in the sub-frame, and the number of FD Μ symbols included in the time slot are Can be modified. This hyperframe can also be called a radio frame. Figure 4 illustrates the relationship between a superframe, frame, sub-frame, and Ο F D 14 14 200922182. In Figure 4B, a superframe has a length of 20 milliseconds and consists of 4 frames, each frame having a length of 5 milliseconds. There is a hyperframe header at the beginning of the superframe, which includes the superframe header system information and broadcast messages. The hyperframe header can have an architecture consisting of several symbols or a number of sub-frames. A frame of 5 milliseconds in length consists of 8 subframes, each subframe having 6 OFDMA symbols.

Figure 5 illustrates a super-information framework in accordance with an exemplary embodiment of the present invention. The super frame is divided into a common control area and a plurality of categories. The normal control area is an optional area that is optionally included in the super message frame. The normal control signal for each user is transmitted via the normal control area located at the beginning of the hyperframe. If the normal control area is not included in the superframe, the normal control signal can be transmitted via the dedicated control area. A category consists of a dedicated control area and a data area. The dedicated control area and the data area are arranged in an alternating pattern. The data area assignment information is control information that directs the data area to which the resource control is assigned by the dedicated control area. The data area assignment information may be included in the normal control area or the dedicated control area. In this case, the dedicated control area may not assign resources to some of the data areas due to the state of the network being loaded or for other reasons. If it is determined that the tributary area indicated by the poor area is not the tribute area, the exclusive control area includes resource assignment information, which is a resource for each user in the data area guided by the information area assignment information. Refers to 15 200922182 faction. The data area assignment information transmitted in the exclusive control area of category 1 may be a control signal, which may indicate a data area belonging to the category 1 or a data area indicating category 2 different from the category 1. Although the figure shows that there are three categories in the superframe, it should be understood that the number of categories may be more or less than three.

Figure 6 illustrates a super-frame structure in accordance with another exemplary embodiment of the present invention. The normal control area, the dedicated control area, and the data area included in a super frame are divided into multiple sub-frames. The Transmission Time Interval (TTI) is the time required to transmit a subframe. Each zone may include at least one subframe. In Fig. 6, the common control area and the dedicated control area included in the super frame are respectively composed of a sub-frame, and the data area is composed of 4 sub-frames. Therefore, the super frame has 11 sub-frames, which constitute a common control area, a dedicated control area and a data area. Figure 7 illustrates a superframe architecture in accordance with yet another exemplary embodiment of the present invention. In Figure 7, a category is illustrated which is part of the super-text framework. Different from the size of the dedicated control area of the super frame in FIG. 6, the exclusive control area of the super frame in FIG. 7 may be smaller than a sub-frame. That is, the dedicated control area can occupy an area smaller than a sub-frame and can be changed or fixed in a sub-frame according to the system. If the size of the dedicated control area is changed within a sub-frame, and 16 200922182 is fixed, the dedicated control area always occupies one part of a sub-frame, and is not included in one of the sub-frames of a super frame. Other parts of the dedicated control area can be included in a data area. The size of the dedicated control area can be pre-defined as a predetermined size or can be known via a common control area. Figure 8 illustrates a method of assigning a data area and a feedback channel in accordance with an exemplary embodiment of the present invention.

For convenience of explanation, the super-message framework used in the F D D system is shown. However, the present invention can be applied to a super-frame structure used in a T D D system. The downlink superframe consists of a common control signal and three categories. The data area for each of category 1 to category 4 consists of 4 sub-frames. The normal control area can be included in the super message box as appropriate. If the normal control area is not included in the super message frame, the super frame consists only of these categories. The uplink hyperframe is not divided into normal control areas and multiple categories, but is divided into sub-frames. The data area assignment information 1 and 2 directs the data area to which the resource is assigned by the dedicated control area. The data area guided by the information area assignment information 1 of category 1 is the two rear sub-frames in the data area of the category 1 and the two front sub-frames of the information area of the category 2. The data area indicated by the information area assignment information 2 of the category 2 is the two rear sub-frames in the data area of the category 2 and the two front sub-frames of the data area of the category 3. That is, the exclusive control area may assign resources to the data areas belonging to its category, and may also assign resources to other types of data areas. The data area assigned by the exclusive control area to 17 200922182 indicating resource allocation may be continuous or non-contiguous.

In addition, the data area to which the dedicated control area indicates the resource assignment may be adjacent to the exclusive control area, or may be separated from the dedicated control area by some subframes. That is, the dedicated control area may be spaced apart by a specified number of sub-frames before the dedicated control area assigns a resource data area to it. This provides time for the user equipment to decode the data area assignment information received from the dedicated control area in the downlink. Therefore, the user equipment that does not need to transmit or receive only decodes the resource assignment information of the dedicated control area without decoding the subframe of the data area. If there is no data to be received in the downlink or the user equipment that has no data to be transmitted in the uplink only decodes the data area assignment information, the power consumption caused by decoding the sub-frames belonging to the redundant data area can be eliminated. The uplink hyperframe periodically transmits downlink channel information ("feedback information") for scheduling via the feedback channel. Control signals, such as CQI and PMI, that should be periodically fed back are primarily transmitted via the feedback channel. The feedback channel in the uplink super-frame is located in several sub-frames before the dedicated control area of the downlink super-frame, and the number of sub-frames can be a specified value. Therefore, feedback information is received in advance, and the feedback information is used for scheduling. The base station can directly transmit new resource assignment information, including feedback information, in the dedicated control area. Therefore, the user equipment can reduce the delay from the transmission time of the feedback information to the data transmission/reception time ("feedback delay") by using the new resource assignment information including the feedback information. In the system of FIG. 8, if the user equipment transmits the feedback information 1 to the base station via the feedback channel 1 of the uplink hyperframe, the feedback information 1 is applied to the exclusive after the two sub-frames. Gongyuan of the control area assigned Gongxun. The maximum feedback delay for the transmission time from the poor source to the downlink is 6 TTI.

Hereinafter, the number of sub-frames in which the feedback channel leads the dedicated control area is referred to as the leading position. In Fig. 8, since the feedback channel 1 leads the two sub-frames of the exclusive control area of the category 2, the leading position of the feedback channel 1 is 2. The base station can transmit information about the leading location via the normal control area. Control signals, such as C QI and Μ Μ I, which should be periodically fed back, are primarily transmitted via the feedback channel. The feedback channel is preceded by a subframe before the dedicated control area, so that the base station can schedule before transmitting the dedicated control area. The base station can predetermine the lead position and transmit feedback information. Alternatively, the base station may update the lead positions within each hyperframe or during several hyperframes and notify the user device of the lead position. Although four sub-frames are shown in the data area t, the present invention is not limited thereto. Figure 9 illustrates a method of assigning a data area and a feedback channel in accordance with another exemplary embodiment of the present invention. For convenience of explanation, the super-message framework used in the F D D system is shown. However, the present invention is applicable to the super frame structure used in the TD D system. The data area designation information 1 and 3 of the downlink designate a data area adjacent to the exclusive control area. Data area assignment information for the downlink 2 19 200922182 Specifies a data area corresponding to the 4 subframes from the frame following the exclusive control area. In the system of Figure 9, if the user equipment transmits the feedback information 1 to the base station via the feedback channel 1 of the uplink frame, the message 1 is applied to the resource information of the dedicated control area after the two subframes. The maximum feedback delay is 4TTI for the transmission of the information to the downlink by the resource. Figure 10 illustrates an example of data area information in the super-frame structure shown in Figure 6. The dedicated control area occupies a sub-frame, such as the information area in the data area shown in Figure 6 is the control signal transmitted in the normal control area or the exclusive control, and may include the location of the data area and the length of the data area. method. The data area assignment information may indicate a data area including the data area (the exclusive control area assigns location information ("starting position") of the child frame to the data area, and may include a continuous message of the starting position The number of frames. The starting position may indicate a relative distance of the sub-message corresponding to the data area indicated by the sub-signal signal from the dedicated control area. The starting position may be 〇 or more, used by each user. The starting position may be irregular, and the number of consecutive sub-frames may be 1, 2 or greater. Information about the number of starting consecutive subframes may be via a normal control area (eg, transmission. Therefore, continuous subframes) The number can be changed according to the information transmitted via the common track or the dedicated control channel. The two sub-roads are super-returned to assign the time domain of the assigned time zone, and the source is the source. The value of the control. The position or the 'BCH' control pass 20

200922182 In Figure 10, the starting position of the data field indicated by the data area assignment information is 1, and the number of consecutive subframes is 2. That is, the data area indicated by the data area assignment information starts from a position separated from the exclusive area by a sub-frame, and the two sub-frames after the start position are used as information for assigning resources to the exclusive control area. region. Figure 1 1 illustrates an example of data area information in the super-frame structure shown in Figure 7. The dedicated control area occupies one of the sub-frames, as shown in Figure 7. Therefore, the sub-frame as the starting point of the data area includes the exclusive control field. Whether the dedicated control area occupies one part of the sub-frame can be indicated by the general control area. Correspondingly, if the exclusive control area is one of the sub-frames, the starting point of the starting position of the data area is 〇. In Fig. 1, the starting position 2 of the data area indicated by the information area assignment information is obtained, and the number of consecutive sub-frames from the starting position is 3. Figure 12 illustrates the feedback channel in the uplink in accordance with the present invention. The uplink hyperframe consists of a plurality of sub-frames. The feedback channel occupies a sub-frame. The feedback channel 2 occupies a portion of a sub-frame. The feed channel can be fixed to occupy a sub-frame. The size of the feedback channel can be determined or can be changed as part of a sub-frame within a sub-frame. Fig. 13 is a flow chart illustrating a data transfer method in accordance with an exemplary embodiment of the present invention. The data area assignment information is about the location and size of the data area to which the specific proprietary control area assigns resources in the downlink (or uplink) hyperframe. Before the transmission of the data, the base station of the base station, the Ministry of Communications, >

200922182 This information area is assigned information (step S 2 0 0) to ensure a data area to be sent to the data. The base station transmits the data area assignment information (S 2 1 0 ) to the user equipment. The user equipment can know which subframe of the data area can receive the downlink hyperframe by using the data area assignment information. The data area assignment information can be transmitted in the normal control area or in the exclusive control area when there is a normal control area. The base station transmits the data by using the resources for scheduling the entire data area (step S220). Figure 14 illustrates a method of transmitting a hyperframe in accordance with the present invention. Each hyperframe includes a common control area, and the general control includes a preamble. In the common super-frame structure, the normal control channel is transmitted via the hyperframe, and the preamble is used for the time synchronization of the superframe. The preamble of the hyperframe requires a long transmission period to reduce the maintenance burden. The foregoing can be transmitted via the data area or the dedicated control area and the super preamble to reduce the delivery time. Figures 15A and 15B illustrate a configuration example of a proprietary control in accordance with the present invention. Figure 15A illustrates a set of exclusive control regions using F D Μ. This dedicated control region can be assigned by subchannels of a particular frequency band. The figure illustrates a configuration example of a dedicated control area using TDM. This control area can be assigned by a specific symbol on the timeline. As the present invention, the interval of the transmission step is not assigned to the previous area. The frame area of the previous section is 1 5Β Exclusive 22

200922182 In an example, one part of the exclusive control area can be constructed by F D , and part of it can be constructed by TDM. Remaining data area of the sub-frame included in the dedicated control channel. Pre-existing control area indication, as shown in Figure 8. Alternatively, the dedicated control channel of the corresponding subframe indicates the remaining data area, as shown in the figure. Figures 16A and 16B illustrate an example of a dedicated control area for the remaining zone in accordance with the present invention. Diagrams 1 6 A and 1 6 B are exemplary and can be used independently with the configuration of the following proprietary control areas. The sub MAP Sub can be used as a dedicated control area indicating the data areas S #0 to S#5. Sub-MAP 1 to Sub-MAP η-1 can be used as a dedicated control area, a data area of the downlink subframe. Figures 17 and 17 illustrate an example of arranging a dedicated control region in an FDD frame in accordance with the present invention. In Figure 17A, the second dedicated control region follows a super-header region. In Figure 17B, the second dedicated control area is followed by a superframe header area. If the dedicated control area is in front of the superframe field in the F D D frame, the dedicated control area may indicate the domain of the superframe area or the remaining area of the next dedicated control area. In addition, the predecessor area may include information for assigning available resources to the sub-data area up to the superframe header area.

Figures 18A through 18D illustrate the presence of a frame field in TDD in accordance with the present invention in TDD and may be acted upon by a field such as a ninth field, or a -MAP 0 sub-MAP. 23 in the exclusive control box of the remaining area of the district

200922182 A dedicated control area in front of the header area of a superframe. If the superframe header area and the dedicated control area are in the same sub-message, the resources used to transmit the dedicated control channel may be insufficient. Therefore, the placement of the control area may cause the dedicated control area not to overlap with the super-frame header area, and the super-frame header area is a sub-frame, which is in the normal control area and the preceding text. If the dedicated control area is located before the head of the superframe, as shown in Figures 18A through 18D, the dedicated control area may include information for available resources between the dedicated control area and the head of the hyperframe. Assigned to this data area. Figures 19A through 9F illustrate a dedicated control region in a TDD system frame in accordance with the present invention, each dedicated control region being located before a hyperframe header region relative to a region. If the exclusive control area is located just adjacent to the head area of a superframe, the symbol "A" indicates the old area. For example, the legacy area can be used in the area of the user equipment of the IEEE 8 0 2.1 6e system, which is one of the systems of the IEEE 8 0 2.1 6m system. The old area includes an old user device, that is, an old one. Unlike Figures 18A through 18D, Figures 19A through 19F are guaranteed to be compatible with older equipment. If the old area is arranged in a superframe area, the exclusive area can be arranged in a subframe that does not overlap the old area. If the number of old areas increases, as shown in Figure IF, the compatibility with the old user equipment can be improved, but the delay is increased in user equipment supporting IEEE 802.16m systems. . The old parameter of the frame-specific standard domain is for the first one. There is a new 24 200922182. The 2 0 A picture and the 20th picture illustrate an example of arranging a dedicated control area in a super-frame of a TDD system according to the present invention. . The superframe header includes the normal control area and the previous section. The normal control area can indicate how many sub-frames are managed by each dedicated control area. The dedicated control area can be placed without overlapping the sub-frame of a superframe header area. The remaining area of the superframe header can be assigned for other purposes using the previous dedicated control area located before the superframe header. For example, if multiple carriers are used, the previously dedicated control region may indicate a frequency band that is not used as the header of the hyperframe. Figures 2 1 A through 2 1 C illustrate the arrangement of dedicated control regions for each frequency band in accordance with the present invention.
