According to e.g. of the present invention embodiment also Figure 4 shows a transmission device is a method for managing link in.

Also said surface reference to an 4, the device 100 said transmission, said transmission device 100 and receiving device 200 401 step monitors a status of link between the.. In other words,, the said link status monitoring the transmission device 100. For example, the transmission device 100, RSSI (Received Signal Strength Indicator), SNR (Signal to Noise Ratio) wireless such as packet error rate or index (PER: Packet Error Rate) through monitoring link status can be said.

the transmission device 100, in a step 403, to determine said link state deactivated. For example, the transmission device 100, said link state when is hereinafter prescribed threshold value, said link state can be judged to be at an is degrading. While, the transmission device 100, said link state is said exceeds the a predetermined threshold, said link state is not deterioration in. parallel parking operation can be judged to have undergone an aspect. Receives deterioration in said link state is, the device 100 transmission said link status said a returned to its step 401 can be monitoring.

Said link state is degrading when the target is judged to be, the transmission device 100, in a step 405, said link corresponding to at least two color pixels and decides the rates of data transfer. the transmission device 100, the data transmission rate according to said link state during range said can be changing the rates of data transfer.

I.e., the transmission device, said link state is degrading when, by lowering the rates of data transfer, said said for transmitting/receiving a packet can be maintain a link.

According to other embodiment of the present invention, said device receiving said a link state can be monitored by the OS. For example, the device receiving said, RSSI, SNR based on at least one said. able to monitor the link. In addition, link status said received result the monitoring device is said beamforming based on the. can be determined.

Figure 5 shows a transmission device of the present invention embodiment also according to e.g. other for managing link in is a method.

Also said 5 reference to an surface, the transmission device 100, device 100 and receiving device 200 in step 501 between said transmission monitoring the link status. For example, the transmission device 100, RSSI, such as SNR wireless indicator or said through packet error rate can be monitoring link status.

the transmission device 100, in a step 503, said link state to determine a deactivated. For example, the transmission device 100, said link state when is hereinafter prescribed threshold value, said link state can be judged to be at an is degrading. While, the transmission device 100, said link state is said exceeds the a predetermined threshold, said link state is not deterioration in. parallel parking operation can be judged to have undergone an aspect. Said link state is deterioration in receives, said a returned to its step 501 the device 200 transmission said link status can be monitoring.

the transmission device 100, when the target is judged to be is degrading link state said, in a step 505, performs beamforming. The beamforming said, plurality of arranged (array) antenna (antenna) is implemented via, antenna gain (gain) , the, can transmit data, the distance available can be have a bend extending to the circuit. In addition, said capable of beamforming said since the reverse link has a higher a directional antennas, different antennas directions can be link. If, said transmission device 100 and said if device 200 using omni directional antenna is received, said transmission device 100 and said receiving device 200 the only one link or channel between (the various pathway (path) no meaning is not), resulting in the channel characteristics also can be only one. However, said transmission device 100 and receiving said said device 200 is capable of beamforming in case of using the plurality of array antennas, said antennas each beam direction according to said received transmission device 100 and said device 200 between the plurality of channels or links are can be formed. Thus, state or characteristic thereof of said number of links to can be different. , the transmission device 100, at least one of number of links to said link when is, the implementation illustrated also said 4 without changing the rates of data transfer, the beamforming said, said transmission device 100 and better between said receiving device 200 can be search the link and into the.

Also 6a to 6e according to e.g. the of the present invention embodiment the beamforming for carrying out transmission device is shown that method are..

The data 6a also said if the Ethernet when heating is carried out in the is. it is shown a beamforming. Also said 6a reference to an surface, said transmission device 100 in one link packet delivering rate (packet delivery rate) decreases, the 601, queue level reception of said receiving device 200 605 KIPO 2007. For example, said packet delivering rate when silicon layer and the substrate 601, the number of packets being transmitted to said receiving device 200 a sampling pulse according to a clock, said received queue level may 605 is reduced. , the transmission device 100, said packet delivering rate 601 603 predetermined beamforming threshold be less than, said beamforming can be. Beamforming section 607 during said beamforming, in which crosstalk is suppressed, said transmission device 100 the receiving device can't send data packets to. Thus, the queue level transmission of said transmission device 100 605, 607 said beamforming section reduces the as. The, said beamforming threshold 603 low, due to performing beamforming late, said beamforming said received queue level is 0 in an evaporator is supplied to the. can occur. Thus, service number door to the ball number. can occur. For example, device 200 is received from said transmission device 100 between said embodiment for medical imaging received one case power output unit for outputting an electric device, said. can be disconnected output medical Image.

The void also said received queue level 6b (empty) to prevent to high beamforming threshold 609 when the mother pipe having a. it is shown a. Also said 6b reference to an surface, the transmission device 100, said beamforming low said received queue level is due to threshold formed in 0 prevent, said high beamforming threshold 609. may be established. the transmission device 100, packet transmission is reduced when, due to high said beamforming threshold 609, low beamforming threshold 603 said faster than when using beamforming can be. Thereby, said 0 605 is received before the queue level may complete KIPO & said beamforming.

Also 6c continuously brake only exemplary the beamforming is performed. Also said 6c reference to an surface, said transmission device 100 601 delivering rate of packets decreases, the, queue level reception of said receiving device 200 605 KIPO 2007. For example, said packet delivering rate when silicon layer and the substrate 601, the number of packets being transmitted to said receiving device 200 a sampling pulse according to a clock, said received queue level may 605 is reduced. , the transmission device 100, said packet transmission rate predetermined high beamforming threshold 601 609 be less than, 1 second beamforming can be. In the case of also said 6c, the beamforming second said 1, said received queue level is 0 605 is completed before the is. However, said packet delivering rate 601 609 threshold beamforming high said again be less than, the transmission device 100 performs beamforming second 2. Due to said high beamforming threshold 609, in beamforming said second 1 queue level is received but can be realized is 0, beamforming continuous, i.e., due to said 2 second beamforming, said received in said 2 second beamforming is queue level is 0. In other words,, 609, although a high said beamforming threshold, said received queue level is said 2 second beamforming is begins to low, said received queue level is in said 2 second beamforming can be is 0.

Also 6d beamforming has beamforming according to delivering rate packet after a predetermined value is. examples of situations where. Also said 6d reference to an surface, the transmission device 100, packet transfer rate threshold beamforming 613 whether or more beamforming based on the perform KIPO &. Also said as shown in 6d, said beamforming 613 said packet transfer rate exceeds a threshold, said. normal does not performing beamforming the transmission device 100. In addition, packet transfer rate said beamforming 613 if less than said threshold, the said transmission device performs beamforming. However, said packet transfer rate but less than said threshold beamforming 613, 615 which a quality threshold service when greater than or equal, said beamforming unnecessary beamforming can be is.

Also 6e a continuous beamforming takes into account the level queue receives on/off status from an number when the amount of the beamforming whether the exemplary. Also said 6e reference to an surface, the transmission device 100, said 2 second beamforming in an evaporator is supplied to the receiving queue level is 0 a bit is inserted for identifying the of, said 2 based on which a quality threshold service 615 [...] may second beamforming performance number. The 615 which a quality threshold service said, said transmission device 100 is performing beamforming second said 2 after beamforming second said 1 determine whether to a basis for projecting the. value. The 615 which a quality threshold service said, device 200 quality of service in said packet delivering rate 601 according to said received can be determined based on. For example, the transmission device 100, after beamforming second said 1, again when the reduction of the packet delivering rate 601, 601 delivering rate packet said said service is to improve convenience of a user by which a quality threshold 615 can be. the transmission device 100, said decreasing said packet delivering rate 601 615 which a quality threshold service if not, the mobile is, without having to perform a second beamforming said 2 can be or delay. According to of the present invention embodiment, the transmission device 100, where a queue state reception of device 200 receiving said predetermined criteria is based on whether the second said 2 makes it possible to determine whether the KIPO & performing beamforming.
