The present invention relates to IEEE 802.15.3 communication, which is a wireless personal area network (WPAN) standard, and more specifically, to improve transmission efficiency in the IEEE 802.15.3 communication method. It is about how to respond.

The IEEE 802.15 Working Group is setting the standard for WPAN, which consists of mobile computing devices within short-haul networks such as PANs, and includes Home Automation, Remote Control, and Ubiquitous Sensor Networks. The movement to apply it is active.

In particular, the recently completed IEEE 802.15.3, also known as HR-WPAN (High Rate-WPAN), aims for a wireless communication network suitable for applications requiring high data rates of 55Mb / s or more, Short distance of 5m to 55m for data transmission over the wireless network, data rate of more than 55 Mbps, dynamic topology configuration of network components, TDMA support for QoS of streams, peer-to-peer connectivity -Peer Connectivity).

The above-mentioned Personal Wireless Network (WPAN) including IEEE 802.15.3 refers to a wireless ad hoc data communication system in which a plurality of independent devices can transmit general data, voice and multimedia data to each other. Such a system defines an individual's behavior radius, that is, all directions within 10 m, as its communication area, and can provide data transmission services that an individual needs, such as transmitting voice data or a video stream or transmitting general data.

 The basic communication range of a personal wireless network is based on a short range personal area within 10 meters as described above, and may be a wired or wireless local area network (LAN), a city network (MAN), a broadband network (WAN), or the like. It can work in conjunction with a wireless network such as Wireless LAN.

In general, in a wired network such as Ethernet, the address assigned to each device does not change, but in a private wireless network, the address refers to the sending / receiving device for which data is provided and is usually without a fixed address. It is dynamically allocated according to the situation.

 Personal wireless networks, on the other hand, can serve fixed, portable and mobile devices. One important feature of portable and mobile devices is that the power source consists mainly of batteries. Accordingly, efficient power management technology is very important because of the limited power capacity of the battery, and the effective design of the protocol of the physical layer or data link layer as well as the component and circuit design is important to reduce power consumption.

The most basic element of a personal wireless network is a device (DEV) (or station), and a piconet is configured when there are two or more stations operating on the same radio frequency channel within the personal active area. Devices are divided into master and slave according to their roles. The master acts as a piconet manager (PNC) that manages the entire piconet, and there can only be one in the piconet. The master controls the slave by broadcasting a beacon. The slave can transmit / receive data under the control of the master.

The piconet is started by the master sending a beacon packet. The beacon packet has reference information about the network, and all slaves in the piconet synchronize the network using the reference information in the beacon packet. As illustrated in FIG. 1, the superframe includes three parts, that is, a beacon period, a contention access period (CAP), and a channel time allocation period (CTAP). The length is variable.

First, in the beacon period, the master transmits a beacon packet having network reference information to the slaves. In the contention period, the slave and the master transmit command packets such as network join request / disassociation request / allow, resource allocation request / allow, and connection request / allow in a random approach. During the contention period, since the exclusive access to the medium through the exclusive allocation of time by the master is not guaranteed, each device accesses the medium using the competitive CSMA / CA. Accordingly, the devices will send a packet if there is a packet to send and the medium is empty for a backoff time.

In an assigned section (CTAP), a device assigned a time slot by a time division multiple access (TDMA) scheme transmits synchronous / asynchronous data and a command packet during the corresponding slot. For example, in FIG. 1, n time slots CAT1, CTA2,..., CTA n-1, and CTA n are time-divided in the allocation interval CFP of the mth superframe #m. A guard time is inserted between slots.

During the allocation interval, each device has exclusive access to the medium for the time slots it allocates. The master distributes time slots in the allocation intervals to each device. During the distributed time slots, each device has exclusive access to the media, and during the assigned slots, each device exchanges data frames and ACK frames for them 1: 1 with the device that they want to exchange data with without master intervention. do.

On the other hand, three types of ACK policies are described in the IEEE 802.15.3 standard. The first is an immediate response (Imm-ACK), in which all ACKs are sent for all media access control (MAC) data frames. This method has the advantage of guaranteeing quality of service (QoS) through the immediate transmission of ACK, while in the case of good channel condition, it sends a lot of ACK unnecessarily, resulting in high power consumption and low throughput. There is a disadvantage.

The second ACK policy, a no-ACK policy, is a method that does not send an ACK at all, and is mainly used in real-time traffic. Since there is no retransmission in the MAC layer, this method does not guarantee QoS when the channel condition is poor and significantly degrades throughput.

Finally, the delayed response (Delayed-ACK) is limited to the isochronous stream (use range). Here, isochronous means a transmission mode that transmits a frame to a receiver by maintaining a timing signal sent from a transmitter as it is known to a person skilled in the art. For example, when isochronous data such as voice or video is mainly transmitted. It is used. In the IEEE 802.15.3 standard, isochronous streams are allocated with CTAs for every superframe and transmitted, and according to the Delayed-ACK policy, only when a transmitting device requests an ACK from a receiving device.

As such, the conventional IEEE 802.15.3 standard mainly uses Imm ACK and No ACK for general data transmission. However, in the wireless environment where there is little error, although ACK is not necessarily required in the MAC layer, the policy of Imm-ACK causes ACK to be overhead in this ideal environment. That is, the energy consumption for transmitting the ACK is increased, and the throughput is significantly lower than when the No-ACK policy is used because of the ACK transmission time. On the other hand, when the No-ACK policy is used in the presence of an error, a significant performance degradation is expected in terms of throughput. On the other hand, since the use of the Delayed-ACK policy described above is limited to isochronous streams, there is a disadvantage that it is not suitable for general data transmission.

In order to solve the above problems, the present invention provides a dynamic ACK policy that can improve communication efficiency and reduce power consumption in response to changes in the channel environment in the MAC layer of IEEE 802.15.3 communication. Its purpose is to.

Steps.

In this case, the ACK processing step may exponentially increase the number of data frames continuously transmitted or increase the number of data frames continuously transmitted when a predetermined number of response (ACK) frames are received. .

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

2 illustrates an operation flow of a dynamic-ACK according to a preferred embodiment of the present invention, and FIGS. 2A and 2B illustrate cases where an error does not exist and a case where an error exists. It is.

Referring to FIG. 2A, as described above, a sender assigned a channel transmits a data frame 1 to a receiver. In response to the normal reception of the frame 1, the receiving side transmits an acknowledgment (ACK) frame to the transmitting side. When the transmitting side normally receives the ACK, the transmitting side sequentially transmits two data frames 2 and 3. The receiving side informs the transmitting side of the normal reception of the two data frames 2 and 3 with one ACK. The transmitting side then transmits four data frames 4 through 7 and receives one ACK for all of these frames. At this time, the ACK frame for the data frames 4 to 7 confirms reception of all four data frames, or, for example, confirms reception of the last / last frame 4 or 7 which is a part thereof. It can be implemented to recognize that these entire frames are normally received.

As described above, according to the preferred embodiment of the present invention, when the data frame transmitted by the transmitting side is normally received at the receiving side, the channel environment is determined to be good, and thus the number of data frames transmitted without ACK is gradually increased. Acknowledgments for these data frames are collectively performed with ACK frames.

Next, referring to FIG. 2B, the sender, which has confirmed normal reception of the data frame 1 from the receiver, transmits two data frames 2 and 3. As described above. At this time, assuming that an error has occurred in the data frame 3, the receiving side notifies the transmitting side of abnormal reception of frame 3 (NAK3). Therefore, after receiving the NAK3 response frame, the transmitting side retransmits the data frame 3 in which the error has occurred and receives the response frame to confirm that there is no abnormality in the retransmission data. In this way, after it is confirmed that there is no abnormality with respect to the single data frame, as described above, the plurality of data frames 4 and 5 are collectively transmitted.

FIG. 3 compares the operations of the conventional Imm-ACK and the No-ACK, and the Dynamic-ACK according to the preferred embodiment of the present invention when there is no error, and the Delayed-ACK defined in the IEEE 802.15.3 standard Do not compare because use is limited. Meanwhile, as described above, each slave node DEV receives a synchronization signal from the master node during the beacon period, and freely transmits and receives data competitively during the contention period CAP. In the allocation period CTAP to which the present invention is applied, It is operated by receiving time allocation between two nodes.

Referring to FIG. 3, if there is no error, the Imm-ACK policy receives an ACK frame for each data frame DATA1 to DATA5 and then transmits a subsequent data frame, thereby lowering transmission efficiency. In the case of No-ACK, since the transmitting side transmits only the data frames DATA1 to DATA5 as shown, and the receiving side does not transmit the ACK frame, transmission efficiency is maximized.

On the other hand, the dynamic ACK according to the preferred embodiment of the present invention initially receives an ACK frame for one data frame DATA1 like the Imm-ACK, and when the data is normally transmitted, the transmitting side transmits the ACK frame. Increasing the amount of data exponentially. That is, the transmitting side sends two data DATA2 and DATA3 and receives an ACK. Accordingly, when normal reception is confirmed, the transmitting side continuously transmits four data DATA4 to DATA7 and receives the ACK. Meanwhile, in the preferred embodiment of the present invention, a case in which the amount of data transmitted by the transmitting side is exponentially increased is illustrated, but it is also possible to increase by a certain number, and the upper limit is on the number of data continuously transmitted without receiving an ACK. May be given.

4 compares the operations of the conventional Imm-ACK and the No-ACK, and the Dynamic-ACK according to the preferred embodiment of the present invention when there is substantially an error.

Referring to FIG. 3, according to the Imm-ACK policy, the transmitting side waits for receiving an ACK frame after transmitting the data frame DATA1. At this time, when the ACK frame is not received or is abnormally received as shown in the drawing, or when a retransmission request (NAK) frame indicating an abnormal reception is received, the data frame DATA1 is retransmitted and the ACK frame is received. do. Subsequently, when the data frame DATA2 is transmitted and an error occurs during the transmission of the data frame as shown in the drawing, the receiving side may not transmit the ACK frame, and thus the transmitting side may not receive the ACK frame. Resend

In the case of No-ACK, even if an error occurs in the data frames DATA2, DATA4, and DATA7 as shown in the figure, the sender cannot determine whether such an error has occurred. Send the data.

Referring to the dynamic-ACK, the transmitting side transmits the data frame DATA1 and normally receives the ACK frame, and then transmits two consecutive data DATA2 and DATA3. At this time, assuming that an error occurs in the third data DATA3 as shown, the receiving side transmits a NAK frame NAK3 requesting retransmission of the data DATA3, and the receiving side receives the corresponding data DATA3. Resend). The receiver immediately transmits an ACK because an error has occurred previously. Subsequently, when the transmitting side receives the ACK of the retransmitted data DATA3 and confirms that the data has been received normally without error, the transmitting side transmits two consecutive data DATA4 and DATA5 and waits to receive the ACK.

5 illustrates a structure of a modified MAC frame to perform a dynamic-ACK policy according to a preferred embodiment of the present invention.

As shown, the standard MAC header includes a stream index, a fragmentation control, a sender ID (SrcID), a receiver ID (DestID), a PNID, and a 2-byte frame control (Frame). Control)

In the frame control unit, the protocol version transmitted first is composed of 3 bits (b0 to b2), and the frame type (FrameType) is defined as 3 bits in the current standard, and the Beacon frame, Imm-ACK frame, and Delayed One of an ACK frame, a command frame, and a data frame is selected.

In the preferred embodiment of the present invention, the dynamic ACK frame is added to the frame type, and the operation is performed when the aforementioned dynamic ACK frame is used in the 2-bit response policy b7 and b8. Define a Dynamic ACK Policy. In addition, the 5-bit reserved bits b11 to b15 may be used in combination with the above-described Dynamic ACK policy bits b7 and b8 to indicate a location where an error occurs. ACK and NAK, respectively indicating normal / abnormal reception, can be distinguished by using two bits or one of the bits of the ACK Policy (b7, b8), alternatively one of the reserved bits b11 to b15. The bits can also be used to distinguish between ACK and NAK frames.

In the following description, an ACK policy (b7, b8) is used to distinguish between an ACK and a NAK, and a combination of the NAK and the reserved bits is used to indicate the number of an error frame.

Figure 6 shows a modification showing a method of transmitting a dynamic response (Dynamic ACK) data frame using a policy according to an embodiment of the present invention in order, and the number of frames to be sequentially transmitted to the 2 ^{K (K} = 0,1 , ..., 5) referred to home, number of the frame where the error occurred in 2 ^K number of data frames (N, N = 0,1, ... , 31) is displayed on the reserved bits of the NAK frame.

As shown, when the transmitting side initiates frame transmission, the counter K is initialized to 0 and transmits one frame (S600). Subsequently, the transmitting side waits for reception of the response frame (S605), and then receives an ACK frame indicating normal reception (S610), or receives a NAK frame indicating a reception error (S615), and during a predetermined time. The ACK / NAK frame may not be received (S620).

In the case of the above-described step (S610), the data frame is been normally received, and increasing the value of K by one and sends a (S625), the number of subsequent data frames corresponding to 2 ^K (S630). Then, the process returns to the aforementioned step S605 and waits for reception of the response frame. Meanwhile, in the above-described step (S625), only up to K = 5 in consideration of the number of data frames identifiable as 5 bits of reserved bits can be increased, and then K = 5 can be maintained.

In the case of the above-described step (S615), since the data frame was not normally received, K is reset (initialized) to 0 (S635), and the Nth data frame indicated by the reserved bit of the NAK frame is retransmitted (S640). Subsequently, the process returns to the above-described step S605 to wait for reception of the response frame.

Finally, in the case of the above-described step (S620), K is reset to 0 (S645), and the first frame of the data frame for which normal reception is not confirmed is retransmitted (S650). Subsequently, the process returns to the above-described step S605 to wait for reception of the response frame.

으로 설정할 수 있으며, 여기서

는 X를 넘지 않는 최대의 정수를 의미한다.7 is as showing a variation of Figure 6, when the number of frames to be sequentially transmitted to the 2 ^K d, and share divided by the other counter by an integer J (quotient) is stored in the K value. for example,

Can be set, where

Is the largest integer not exceeding X.

Initial steps S700 to S720 correspond to steps S600 to S620 of FIG. 6 described above, except that J is set to 0 in step S700.

If it is not an error occurs in the step (S710) is, increases the value of J by one and sends the number of the subsequent data frame corresponding to ^{(S725), 2 K (S630} ). Then, the process returns to the above-described step S705 to wait for reception of the response frame. On the other hand, in step S725 described above, in consideration of the number of data frames identifiable as 5-bit reserved bits, J does not increase to 18 or more, for example, maintains J = 15.

When NAK is received in step S715, the value of J is decreased by 1, or alternatively, J = 0 is set (S735). At this time, it is possible to maintain J = 0 only when the existing J is zero. Next, displayed in the reserved bit of a NAK frame from the N-th data frame retransmitted frames and the 2 ^K (S740), it returns to step (S705) and waits for the reception of a response frame.

Finally, if the time is exceeded because the response frame is not received in the step S720 for a predetermined time, the value of J may be decreased by 1 or alternatively, J = 0 may be set (S745). At this time, when J = 0, the value can be set to be maintained. Then, previously transmitted but not the first frame from the data frame not received a response from the frame (N = 0) to 2 ^K retransmission of data frames, and returns to (S750), step (S705) and waits for the reception of a response frame.

According to this modification, since K = 0 is maintained while J = 0,1,2, ACK must be confirmed for these three consecutive data frames, and J = 3 is set. Consecutive data frames are transmitted. In the subsequent steps as well, the normal reception is ensured in three successive transmissions, thereby doubling the number of consecutively transmitted data frames.

If an error occurs or a response frame is not received in the case of doubling the number of consecutively transmitted frames and transmitting the first time, the continuous transmission is performed as the number J = J-1 is decreased in step S735 or S745. The number of frames is halved. On the other hand, if there is no error in the first transmission after increasing the number of consecutive frames, but the error occurs in the second or third time, the data frame in which an error occurred (when receiving a NAK) or the first frame in which normal reception was not confirmed. The same number of frames is retransmitted.

로부터 K=1이 된다. 이에 따라, 상기 무응답된 2개의 데이터 프레임 중 첫번째 프레임만을 전송하고 ACK 수신을 대기하게 되는 것이다.For example, when J = 5, when two data frames are continuously transmitted but no response, J = 4 is subtracted according to step S735, and the two data frames are retransmitted. Nevertheless, if there is no response again, J = 3 is subtracted.

K = 1 from. Accordingly, only the first frame of the two unresponsive data frames is transmitted and the ACK reception is waited.

On the other hand, in the above-described steps (S735, S745), if J = 0 is set regardless of the continuous transmission cycle, one data frame is retransmitted unconditionally and then three consecutive data frames are normally received to increase the number of frames. Let's do it.

Although the preferred embodiment according to the present invention has been described above, this is merely exemplary and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. Therefore, the protection scope of the present invention should be defined by the following claims.

As described above, using the dynamic response policy according to the present invention, it is possible to replace the Imm-ACK and No-ACK provided by the IEEE 802.15.3 standard, the conflicting power consumption and quality of service (QoS) guarantee Conditions can be adaptively adjusted according to channel conditions. For example, when there is almost no error, the power consumption can be reduced and transmission efficiency can be improved by operating like No-ACK. When an error occurs, the service quality can be improved by operating like Imm-ACK.
