Description

Device and method for frame composition in wireless communication system {APPARATUS AND METHOD FOR FRAME STRUCTURE IN WIRELESS COMMUNICATION SYSTEM}

The present invention relates to an apparatus and method for constructing a frame in a wireless communication system, and more particularly, to an apparatus and method for constructing a frame in a wireless communication system of Half Duplex-Frequency Division Duplex (hereinafter referred to as H-FDD). will be.

Today, many wireless communication technologies have been proposed as candidates for high speed mobile communication. Orthogonal Frequency Division Multiple Access (hereinafter, referred to as OFDMA) is one of the candidate technologies for the next generation of wireless communication. The OFDMA technique is being standardized in a working group of IEEE (IEEE) 802.16e.

The wireless communication system defined in the IEEE 802.16e standard performs communication using a frame structure configured as shown in FIG. 1 using a time division duplex scheme.

1 shows a frame configuration of a wireless communication system using a time division duplex scheme according to the prior art.

As shown in FIG. 1, a frame 100 of a wireless communication system using the time division duplex scheme includes a downlink subframe 110 and an uplink subframe 120 through time resources.

In this case, there is a TTG (Transmit / receive Transition Gap) 130 for switching the operation of the terminal between the downlink subframe 110 and the uplink subframe 120. In addition, there is a Receive / Transmit Transition Gap (RTG) 140 for switching the operation of the UE between the uplink subframe 120 and the downlink subframe of the next frame.

Recently, as the demand for multimedia services increases, studies on wide-band wireless communication systems using a plurality of frequency bands in order to transmit a lot of data faster have been conducted. For example, in the case of the H-FDD scheme, the wireless communication system performs communication using two frequency bands. That is, the base station transmits a signal to terminals located in the service area through the first frequency band, and the terminals transmit a signal to the base station through the second frequency band. However, UEs using the H-FDD scheme cannot transmit signals through the second frequency band while receiving signals through the first frequency band.

Therefore, the wireless communication system using the H-FDD scheme operates between the downlink period and the uplink period so that the terminal can transmit a signal through the second frequency band after receiving the signal through the first frequency band. You have to set the transition section.

In this case, since the frequency band in which the terminal receives the signal and the frequency band in which the signal is transmitted are different from each other in the wireless communication system according to the H-FDD scheme, the wireless communication system has the same operation switching interval as in the time division duplex scheme as shown in FIG. Cannot be set. Therefore, in a wireless communication system using the H-FDD scheme, a frame structure including a section for switching the operation of the terminal is required.

Accordingly, an object of the present invention is to provide an apparatus and method for constructing a frame in a wireless communication system of Half Duplex-Frequency Division Duplex (hereinafter referred to as H-FDD).

Another object of the present invention is to provide an apparatus and method for setting an operation switching interval of a terminal in an H-FDD wireless communication system.

It is still another object of the present invention to additionally use one or more symbols among symbols included in a time division duplex frame configuration in an H-FDD wireless communication system as an operation switching interval, and thus, the operation switching interval of the UE in the H-FDD scheme. An apparatus and a method for setting a larger than a time division duplex scheme are provided.

According to a first aspect of the present invention for achieving the objects of the present invention, a frame configuration method for supporting a terminal using a half-duplex (Frequency Division Duplex) scheme in a wireless communication system, the first Spaced apart between the subframes included in the frequency band and the subframes included in the second frequency band by using the average of the operation switching intervals of the terminal, and the subframes included in the second frequency band In the state characterized in that it comprises the step of moving to the right by the difference between the average of the operation switching interval and the operation switching interval of the terminal.

According to a second aspect of the present invention, in a wireless communication system, a terminal device using a half duplex frequency division duplex scheme includes a method for changing an operation switching interval and an operation switching interval of the terminal according to frame configuration information. A controller which controls the transmitter to generate an uplink subframe from a time point shifted to the right by the difference of the average, and controls the radio frequency (RF) processor to switch the operation mode according to a transmission section and a reception section; When the transmission period ends, the signal is switched to the reception mode for receiving the signal of the first frequency band to receive the signal, and when the reception period ends, the signal is switched to the transmission mode for transmitting the signal through the second frequency band. An RF processor for transmitting and generating an uplink signal during a transmission period under the control of the controller And a receiver receiving a downlink signal provided from the RF processor during a reception period and transmitting to the receiver.

As described above, at least one of symbols included in a time division duplex frame configuration in a half duplex-frequency division duplex (H-FDD) type wireless communication system is used as an operation switching interval. By additionally using the H-FDD scheme to set the operation switching interval, there is an advantage that the UE can smoothly switch the operation while maintaining the frame structure of the time division duplex scheme to the maximum.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

Hereinafter, the present invention is a half-duplex-frequency division duplex (hereinafter referred to as H-FDD) scheme in a full duplex-frequency division duplex (F-FDD) wireless communication system. A technique for configuring a frame including an operation switching interval for a terminal of UE will be described.

The terminal of the H-FDD scheme receives a signal from a serving node through a first frequency band and transmits a signal to the serving node through a second frequency band. However, the terminal cannot transmit a signal through the second frequency band while receiving a signal through the first frequency band.

Therefore, the F-FDD system should configure a frame that can support the operation switching interval of the terminal of the H-FDD scheme. In this case, the terminal of the H-FDD scheme is different from the frequency band for receiving the signal and the frequency band for transmitting the signal, so the time required for the operation switching should be longer than the time division duplex (TDD) system. Therefore, the F-FDD system should set the operation switching interval for the terminal of the H-FDD scheme larger than the operation switching interval of the TDD system. For example, when the bandwidth is 10M, the TDD system sets the TTG (Transmit / receive Transition Gap) to 105.714us in consideration of the maximum SSTTG (Subscriber Station TTG) and SSRTG 50us for switching the operation of the terminal, and RTG Set Receive / transmit Transition Gap to 60us. In this case, since the frequency band is changed when the H-FDD scheme is switched, the terminal of the H-FDD scheme should be set to a value of about 100 us greater than SSTTG and SSRTG of the TDD system. In the following description, TTG and RTG of the TDD system will be referred to as TTG (TDD) and RTG (TDD).

When the bandwidth is 10M, the TDD system is composed of 47 Orthogonal Frequency Division Multiplex Access (OFDMA) symbols, one TTG (TDD) and one RTG (TDD). At this time, one OFDMA symbol has a size of 102.87us. In this case, the F-FDD system requires 100us more than the SSTTG and SSRTG of the TTD system in order to switch the operation of the terminal of the H-FDD scheme. Accordingly, the F-FDD system extends the TTG (TDD) section and the RTG (TDD) section by using one OFDMA symbol among 47 OFDMA symbols of the TDD system, as shown in Equation 1 below. -Can be used as TTG and RTG for the UE of the FDD scheme.

Here, the TTG (H-FDD) represents the TTG for the terminal of the H-FDD scheme, the RTG (H-FDD) represents the RTG for the terminal of the H-FDD scheme, and the TTG (TDD) is a TDD system Represents the TTG of, and the RTG (TDD) represents the RTG of the TDD system.

As shown in Equation 1, the F-FDD system sets the TTG to have the same length as adding half of one OFDMA symbol to the TTG (TDD), and sets one RTG to the RTG (TDD). The same length as that of adding half of the OFDMA symbol is set to be the same.

In another embodiment, the F-FDD system may use one or more OFDMA symbols of the TDD system to extend the TTG (TDD) and the RTG (TDD).

As described above, the F-TDD system additionally uses one or more OFDMA symbols in the TTG (TDD) and the RTG (TDD) to configure the TTG and the RTG for the operation switching of the UE of the H-FDD scheme.

In this case, since the UE of the H-FDD scheme configures downlink and uplink using different frequency bands, the F-FDD system may configure a frame including the TTG and RTG using the procedure of FIG. 2. Can be.

2 illustrates a procedure for configuring a frame for a UE of a half-duplex frequency division duplex scheme according to an embodiment of the present invention.

Referring to FIG. 2, first, in step 201, the F-FDD system calculates an average of operation switching intervals for the H-FDD type UE. For example, when an operation switching interval for the H-FDD type UE is configured by adding one OFDMA symbol to the TTG (TDD) and the RTG (TDD), the F-FDD system is represented by Equation 2 below. An average of the operation switching intervals for the H-FDD type UE is calculated.

Here, the GAP represents an average of operation switching intervals for the H-FDD type UE, the TTG (TDD) represents a TTG of a TDD system, and the RTG (TDD) represents an RTG of a TDD system.

The TTG and RTG for the H-FDD type UE are the same as the TTG (TDD) and RTG (TDD) extended by one OFDMA symbol. Accordingly, the F-FDD system may calculate the average of the operation switching intervals for the H-FDD type UE using the TTG (TDD), the RTG (TDD), and the OFDMA symbol as shown in Equation (2). have.

After calculating the average of the operation switching intervals, the F-FDD system proceeds to step 203 to separate the subframes using the average of the operation switching intervals for the H-FDD type UEs. For example, the F-FDD system includes an operation switching interval for UEs of the H-FDD scheme between downlink subframes located in a first frequency band and uplink subframes located in a second frequency band. Spaced to the same size as the average. In this case, in the F-FDD system, the last downlink subframe of the i-th frame and the first downlink subframe of the (i + 1) th frame are also equal to the average of the operation switching intervals for the H-FDD type UEs. Spacing to size In addition, in the F-FDD system, the last uplink subframe of the i-th frame and the first uplink subframe of the (i + 1) th frame are also equal to the average of the operation switching intervals for the H-FDD type UEs. Spacing to size

In another embodiment, the F-FDD system separates downlink subframes located in a first frequency band by twice the average of an operation switching interval for the H-FDD type UEs. In this case, the F-FDD system does not separate the last downlink subframe of the i-th frame from the first downlink subframe of the (i + 1) th frame.

In addition, the F-FDD system does not space between uplink subframes located in the second frequency band. In this case, the F-FDD system averages an operation switching interval for the H-FDD UE between the last uplink subframe of the i-th frame and the first downlink subframe of the (i + 1) th frame. Two times apart.

In step 205, the F-FDD system proceeds to the operation switching interval of the H-FDD terminal and the operation switching interval calculated in step 201 to set the operation switching interval for the H-FDD terminal. Calculate the difference between the means. In this case, the F-FDD system calculates the difference between the average of the operation switching interval calculated in step 201 and the operation switching interval of the terminal of the H-FDD scheme as shown in Equation 3 below.

Here, the TTG (H-FDD) represents the TTG for the terminal of the H-FDD scheme, the RTG (H-FDD) represents the RTG for the terminal of the H-FDD scheme, and the TTG (TDD) is a TDD system TTG of the TG, the RTG (TDD) represents the RTG of the TDD system, the GAP is the average of the TTG (H-FDD) and RTG (H-FDD) of the operation switching interval for the terminal of the H-FDD scheme The same value indicates the size of the region inserted between the subframes.

The average of the operation switching interval may be calculated using TTG (TDD) and RTG (TDD) as shown in Equation 2 above. Therefore, as shown in Equation 3, the difference between the average of the operation switching interval and the calculated operation switching interval for the H-FDD terminal may be calculated by the TTG (TDD) and the RTG (TDD). That is, the difference between the average of the operation switching interval and the calculated operation switching interval for the H-FDD type UE has the same value as half of the difference between the TTG (TDD) and the RTG (TDD). In addition, the difference between the average of the operation switching interval and the calculated operation switching interval for the terminal of the H-FDD scheme has the same value as half of the difference between the TTG and the RTG, which is the operation switching interval of the terminal.

After calculating the difference between the average of the operation switching interval and the operation switching interval, the F-FDD system proceeds to step 207 in which the difference between the average of the dynamic switching interval and the coin switching interval of the second frequency band is increased. Shift uplink subframes to the right. That is, in step 203, an average of uplink subframes of the second frequency band for the dynamic switching period and the coin switching period is separated from each other by using the average of the operation switching periods for the H-FDD type UE. Move to the right by the car.

The F-FDD system then terminates this algorithm.

As described above, the F-FDD system may configure a frame by using a difference between an average of operation switching intervals and an operation switching interval for the H-FDD type UE.

The F-FDD system configures the terminals of the H-FDD scheme into two groups using the method of FIG. 2 so that the UEs belong to the second group when the base station transmits a downlink signal to the UEs belonging to the first group. A frame may be configured as shown in FIG. 3 to receive an uplink signal from the FIG.

3 is a block diagram of a terminal using a half-duplex frequency division duplex scheme according to an embodiment of the present invention.

Referring to FIG. 3, first, the F-FDD system subframes regions 360 and 370 that are the same as the average of the operation switching intervals for the H-FDD type UE as shown in FIG. 3A. Insert between them. Here, the average of the operation switching intervals for the H-FDD type UE is calculated as shown in Equation 2.

For example, the F-FDD system includes a downlink subframe transmitted to terminals belonging to a first group in a first frequency band of an i-th frame and a downlink subframe transmitted to terminals included in a second group. The region 360 having the same size as the average of the operation switching intervals is inserted therebetween. Subsequently, the F-FDD system transmits a downlink subframe transmitted to the terminals included in the second group of the i-th frame and the terminals transmitted to the terminals included in the first group of the (i + 1) th frame. An area 370 having the same size as the average of the operation transition periods is inserted between link subframes.

In addition, the F-FDD system operates between an uplink subframe transmitted by terminals belonging to a first group and an uplink subframe transmitted by terminals included in a second group in a second frequency band of an i-th frame. The region 380 having the same size as the average of the transition intervals is inserted. Thereafter, the F-FDD system includes an uplink subframe transmitted by terminals included in the second group of the i-th frame and an uplink subframe transmitted by terminals included in a first group of the (i + 1) th frame. An area 390 having the same size as the average of the operation transition periods is inserted between the frames.

Subsequently, the F-FDD system performs uplink subframes of a second frequency band on the H-FDD type UE in the frame configured as shown in FIG. 3A as shown in FIG. The frame is shifted to the right by the difference 330 between the operation switching section and the value calculated by Equation 2 above.

In this case, the frame configures a downlink subframe for transmitting a downlink signal from the base station to the terminals of the first group during the first period 310 of the first frequency band. In addition, the base station configures a downlink subframe for transmitting a downlink signal from the base station to the terminals of the second group. Here, the frame structures of FIGS. 3A and 3B are expressed from the base station point of view. Accordingly, the terminal receives the downlink subframe half of a round trip delay (RTD) after the downlink subframe is transmitted due to a delay in a wireless environment.

The frame configures an uplink subframe for transmitting the uplink signal to the base station by the second group of terminals during the first period 310 of the second frequency band. In addition, the second group 320 configures uplink subframes for transmitting uplink signals to the base station by the first group of terminals. Here, the terminal should transmit the uplink subframe half of the RTD before the time point of transmitting the illustrated downlink subframe in consideration of a delay according to a wireless environment.

Therefore, referring to the terminals included in the first group in FIG. 3B, the terminal is located between the first section 310 of the first frequency band and the second section 320 of the second frequency band. TTG 340 is configured to switch operations. In addition, the RTG 300 is configured to switch the operation between the second section 320 of the second frequency band and the first section of the first frequency band of the next frame.

Referring to the terminals included in the second group, the RTG 351 is configured to switch the operation between the first section 310 of the second frequency band and the second section 320 of the first frequency band. do. In addition, the TTG 341 is configured to switch the operation of the terminal between the second section 320 of the first frequency band and the first section of the second frequency band of the next frame.

In another embodiment, the F-FDD system may configure a frame as shown in FIG. 4.

4 is a block diagram of a terminal using a half-duplex frequency division duplex scheme according to another embodiment of the present invention.

Referring to FIG. 4, first, the F-FDD system includes regions 460 and 470 that are equal to the average of operation switching intervals of UEs using the H-FDD scheme as shown in FIG. 4A. Insert between subframes. Here, the average of the operation switching intervals is calculated as in Equation 2.

For example, the F-FDD system includes a downlink subframe transmitted to terminals belonging to a first group in a first frequency band of an i-th frame and a downlink subframe transmitted to terminals included in a second group. The regions 460 and 470 having the same size as the average of the operation switching intervals are inserted in between. Subsequently, the F-FDD system transmits a downlink subframe transmitted to the terminals included in the second group of the i-th frame and the terminals transmitted to the terminals included in the first group of the (i + 1) th frame. Link subframes are placed consecutively.

The F-FDD system continuously positions an uplink subframe transmitted by terminals belonging to a first group and an uplink subframe transmitted by terminals included in a second group in a second frequency band of an i-th frame. . Thereafter, the F-FDD system includes an uplink subframe transmitted by terminals included in the second group of the i-th frame and an uplink subframe transmitted by terminals included in a first group of the (i + 1) th frame. Between the frames, regions 480 and 490 having the same size as twice the average of the motion switching intervals are inserted.

Subsequently, the H-FDD system operates the uplink subframes of the second frequency band in the frame configured as shown in FIG. 4A as shown in FIG. The frame is shifted to the right by the difference 430 of the value calculated in 2>.

In this case, the frame configures a downlink subframe for transmitting a downlink signal from the base station to the terminals of the first group during the first period 410 of the first frequency band. In addition, during the second period 420, the base station configures a downlink subframe for transmitting a downlink signal to the UEs of the second group. Here, the frame structures of FIGS. 4 (a) and 4 (b) are expressed from the viewpoint of the base station. Therefore, the terminal receives the downlink subframe half of the RTD after the downlink subframe is transmitted due to the delay of the wireless environment.

The frame configures an uplink subframe for transmitting the uplink signal by the second group of terminals to the base station during the first period 410 of the second frequency band. In addition, the first group of terminals configures an uplink subframe for transmitting an uplink signal to the base station during the second period 420. Here, the terminal should transmit the uplink subframe half of the RTD before the time point of transmitting the illustrated downlink subframe in consideration of a delay according to a wireless environment.

Therefore, referring to the terminals included in the first group in FIG. 4B, the terminal is located between the first section 410 of the first frequency band and the second section 420 of the second frequency band. TTG 440 is configured to switch this operation. In addition, the RTG 450 is configured to switch the operation between the second section 420 of the second frequency band and the first section of the first frequency band of the next frame.

Referring to the terminals included in the second group, the RTG 451 is configured to switch the operation between the first section 410 of the second frequency band and the second section 420 of the first frequency band. do. In addition, the TTG 441 is configured to switch the operation of the terminal between the second section 420 of the first frequency band and the first section of the second frequency band of the next frame.

Hereinafter, the block configuration of the H-FDD type terminal for performing communication using a frame including an operation switching interval for the H-FDD type terminal in the F-FDD system will be described.

5 is a block diagram of a terminal using a half-duplex frequency division duplex according to the present invention.

As shown in FIG. 5, the terminal includes a transmitter 500, a receiver 510, a controller 520, and an RF processor 530.

First, the transmitter 500 includes a frame generator 501, a resource mapper 503, a modulator 505, and a digital / analog converter (DAC) 507.

The frame generator 501 generates an uplink subframe to be transmitted to the upper node through a second frequency band during a period for transmitting a signal to the upper node under the control of the controller 520.

The resource mapper 503 allocates an uplink subframe generated by the frame generator 501 to a burst of the corresponding link and outputs the burst.

The modulator 505 encodes and modulates the subframe provided from the resource mapper 503 according to the modulation level. Here, the modulation level represents a Modulaton and Coding Scheme (MSC) level.

The digital-analog converter 507 converts the digital signal provided from the modulator 505 into an analog signal and outputs the analog signal to the RF processor 530.

The receiver 510 includes an analog / digital converter (ADC) 511, a demodulator 513, a resource demapper 515, and a frame extractor 517.

The analog / digital converter 511 converts an analog signal provided from the RF processor 530 into a digital signal.

The demodulator 513 demodulates and decodes the digital signal provided from the analog-to-digital converter 511 according to the modulation level.

The resource demapper 515 extracts the actual subframes allocated to the burst of each link provided from the demodulator 513.

The frame extractor 517 extracts the subframe transmitted from the serving node in the subframe provided from the resource demapper 515.

When the RF processor 530 receives a reception period, the RF processor 530 switches to a reception mode for receiving a downlink signal of a first frequency band under the control of the controller 520. Thereafter, the RF processor 530 receives a downlink signal of a radio frequency transmitted by a serving node, converts the signal into a baseband signal, and outputs the baseband signal to the receiver 510.

In addition, the RF processor 530 is switched to the transmission mode for transmitting the uplink signal through the second frequency band under the control of the controller 520 when the transmission period. Thereafter, the RF processor 530 converts a baseband uplink signal provided from the transmitter 500 into a high frequency signal and transmits the signal to a serving node through an antenna.

The controller 520 controls the frame generator 501 and the RF processor 530 according to frame configuration information including an operation switching interval for the H-FDD type terminal. For example, when performing communication using the frame configuration as shown in (b) of FIG. 3, the controller 520 is as much as the difference between the average of the operation switching interval and the operation switching interval as shown in Equation (3). The frame generator 501 is controlled to transmit an uplink subframe at a time shifted to the right. Here, the shifting interval is equal to half of the difference between TTG (TDD) and RTG (TDD) and half of the difference between TTG and RTG.

In addition, the controller 520 controls the RF processor 530 to receive the downlink signal by switching to the reception mode of the first frequency band during the reception period. In addition, the controller 520 controls the RF processor 530 to transmit the uplink signal by switching to the transmission mode of the second frequency band during the transmission period.

In this case, the controller 520 controls the RF processor 530 to switch from the transmission mode to the reception mode during the TTG period and controls the RF processor 530 to switch from the reception mode to the transmission mode during the RTG period. .
