Definitions
- the invention relates to a method for the automatic alignment of antennas of stations of a radio link, a master transceiver and an operating method for a master transceiver. Furthermore, the invention relates to a slave transceiver and an operating method for a slave transceiver and a directional radio arrangement.
- Directional radio systems in particular with wavelengths in the range of millimeter waves (60 GHz, 70-80 GHz, 90 GHz), use antennas with a very strong directivity, ie a very narrow radiation pattern, partly due to frequency-regulatory requirements.
- the typical opening angles of 60 GHz radio relay systems are, for example, between 0.5 ° and 3 °. However, some even more concentrated antennas are in use.
- the very small opening angle of the antennas and the consequent small beam diameters especially in connection with non-fixed distances between two radio stations, lead to great difficulties in the alignment of the antennas.
- microwave radio stations are also referred to simply as stations below. Manual alignment of the antennas is very time consuming and requires additional aids.
- Desirable is thus an accelerated automatic alignment of antennas of a radio link.
- This object is achieved according to a first aspect by a method for the automatic alignment of antennas of stations of a radio link, wherein one station is configured as a master and at least one other station as a slave and in which in a first phase of the master and the slave Coarse scanning for determining a mutual coarse alignment in which master and slave can exchange signals with each other, and wherein in a second phase after the coarse alignment has been identified and set, the master determines a control beam direction of the master and a control beam direction of the slave, hereinafter referred to as master Control beam direction and slave control beam direction are designated, and the slave whose slave control beam direction specifies.
- the master respectively gives a new slave beam direction and a dwell time in which the slave is to receive in this new slave beam direction.
- the master then sends search signals in a predetermined number of its master beam directions without lingering in the master beam directions, the slave performs signal quality parameter determination for each received signal during the dwell time, and stores its results.
- both stations are directed into the respective predetermined control beam direction, the slave transmits the results of the signal quality parameter determination and, on the basis of the signal quality parameter determination, an optimal mutual alignment of the antennas of the master and slave is determined and these are aligned accordingly ,
- the invention is based on the finding that a method for automatic alignment of antennas of a radio link can be accelerated by, after a coarse alignment was found in which the master and the slave can communicate with each other, the master increases its scanning speed. This happens in the present case by leaving no residence time in the respective master beam direction, but changes directly after sending a signal to the next master beam direction and the slave continuously receives signals and only after a search of the master over a predetermined number of its master beam directions of Slave transmitted to the master, in which beam direction he has received signals in which quality.
- the slave remains in this case for each pass on a slave beam direction predetermined by the master and changes only in the next pass on a turn determined by the master new slave beam direction. Using this method, accelerated searches can be performed over all combinations of beam directions of master and slave.
- beam position is meant in relation to antennas in the present application in different embodiments, for example, an orientation of an antenna by mechanical means, or for example, an orientation of the antenna, which alone or additionally by electronically influencing the radiation characteristics, such as beam steering can be adjusted.
- beam direction is not always used in terms of antennas and stations of a radio link in the context of the present application in the sense of a transmission direction, but depending on the context (transmitter or receiver) in the sense of a receive direction.
- the dwell time of the slave in the second phase corresponds to the amount of time the master requires to send seek signals in the predetermined number of master beam directions.
- dwell time is used here for periods of time in which a respective station dwells in a beam direction until the end of a predetermined time independently of signals arriving in this time.
- waiting time is used for periods of time in which a respective station dwells in a beam direction until either a certain signal has arrived or a predetermined time has elapsed.
- coarse sampling in the first phase comprises the following steps: the master sends a search signal in a first master beam direction and then waits for a defined waiting time for a response signal and changes to a second one if no response signal after the waiting time Master beam direction, upon receipt of a response signal, the master sends a start signal in the first master beam direction, with which a second phase is initiated; the slave waits in a first slave beam direction a defined waiting time which is greater than the waiting time of the master for receiving a search signal and changes in the absence of a search signal after the waiting time to a second slave beam direction, upon receipt of a search signal, it sends a response signal in the first slave beam direction.
- This method provides a way of coarse sampling.
- Other methods that can serve to find a combination of a master beam direction and a slave beam direction in which master and slave can communicate with each other are also suitable.
- the master takes over the control functionality for the communication between master and slave and thus enables a controlled communication between both stations during the search. Therefore, the method according to the invention can be used particularly advantageously in TDD-based methods which have no possibility for continuous control.
- the stations therefore work with a TDD-based method. In TDD-based methods, only one frequency channel is used so that the two stations can not simultaneously transmit a continuous signal during a scan of beam combinations.
- a sample of beam combination means here the search of master and slave for combinations of their respective beam directions, in which a communication between master and slave is possible.
- the method is used at stations operating in a frequency range above 50 GHz.
- frequency ranges in some cases high antenna gains and thus very small beam widths are prescribed for frequency regulation in the outdoor area, so that a method for alignment is required.
- very large antennas are necessary to realize high antenna gains.
- high antenna gains Above 50 GHz, even highly concentrated antennas are relatively small.
- the method can also be used in all other frequency ranges, provided that directional antennas are used with adjustable orientation.
- termination criteria for the iterations of the second phase may be defined.
- an abort criterion may be that an alignment has been found in which the signals of the desired quality can be transmitted or a certain number of slave beam directions have been traversed.
- the alignment can be further accelerated. In this case, the search space no longer extends beyond all possible combinations and possibly the optimal combination is not found (for example, if several alignments lead to a contact due to reflections). But this is not a problem because the combination found meets all the requirements for data transmission.
- the missing distance indication requires that always the smallest beam diameter is used, ie the antenna gain, which is necessary for the maximum specified distance of the system. Moreover, in some cases, the use of a larger beam diameter that is a smaller antenna gain frequency regulatory not allowed. In addition, the maximum transmit power required for the largest possible specified distance is also used. However, if the distance of the stations is lower, this can lead to an overload of the input amplifiers on the receiver.
- this results in a communication link not being established can be, because the overdriven signal no response takes place and the transmitter has no knowledge of whether the response is missing due to a lack of agreement of the beam directions or due to an overload of the receiver.
- the master or the slave measures in the first phase when detecting an overdriven signal, the duration of this overdriven signal in the first phase. From the duration of the overdriven signal and a comparison with a desired duration of an expected search or response signal, the reception of the expected search or response signal is then concluded and a response provided in response to the receipt of this expected search or response signal is sent , This embodiment allows the communication between master and slave, even if it has come to an overdrive.
- This embodiment makes use of the insight that communication can be established despite overriding, when the station receiving an overdriven signal measures the duration of the overdriven signal and concludes from this period of time and a comparison of this time duration with a desired duration of an expected signal can that the expected signal has arrived and then sends an appropriate response to the expected signal. It is particularly advantageous for the master in the context of this embodiment, when it receives an overdriven response signal in a first phase, to determine from a received power of the response signal a new transmission power of the search signal which is lower than that previously used and subsequently the master Search signal with the new transmission power sends.
- This process is then preferably carried out iteratively until either a non-overdriven exchange of search signal and response signal has occurred or a presence of an abort criterion is detected without receipt of a non-overdriven signal.
- this method it is possible, in addition to optimizing the alignment of the antennas, to automatically optimize the transmission power and to avoid communication aborts in fundamentally suitable beam directions due to overloading.
- the expiration of a predetermined maximum waiting time is a suitable stopping criterion or the passage of a predetermined number of iterations.
- the first phase is continued with a new master beam direction.
- the master After a non-overdriven exchange of response signal and search signal in a preferred embodiment, the master sends a start signal, with which it triggers the beginning of the second phase.
- the inventive method can be performed not only with a master and a slave, but also with multiple slaves, which are each addressed in different time slots. Thus, the operation of a radio link with more than two stations is possible.
- the invention relates to a master transceiver for operating a radio link, hereinafter master, with a transceiver configured to generate, transmit and receive signals in adjustable directions via at least one antenna and a control unit which is designed for automatic alignment of the antenna, the transceiver unit in a first phase to perform a coarse scan for determining a mutual coarse alignment with a slave transceiver, slave hereinafter to initiate after completion of coarse scanning a second phase and in the second phase of the send Receive unit to specify a master control beam direction and in the slave a slave control beam direction.

- the master is preferably designed to measure the duration of this overdriven signal in the first phase when detecting an overdriven signal, from the duration of the overdriven signal and a comparison with a setpoint duration of one expected response signal to close upon receipt of the expected response signal and to send a response provided in response to the receipt of this expected response signal response.

- Figure 1 shows schematically a method for automatic alignment of antennas of stations of a radio link according to the first aspect of the invention.
- the Method for automatically aligning antennas of stations of a radio link according to the first aspect of the invention is a two-stage process.
- a beam search is performed, in other words a coarse scan for determining a mutual coarse alignment of the antennas of the stations.
- the first station, the master M scans in a first phase quickly over a predetermined number of its master beam directions. For this he selects a master beam direction and sends in this a Discover packet (S1 1 1). Subsequently, the master waits for a response signal in step S112.
- the master does not receive a response signal during the waiting time, it continues its search with step S1 13, switching to the next master beam direction.
- the second station the slave in turn scans in the first phase over a predetermined number of its slave beam directions.
- the scan speed of the slave is slower than the scan speed of the master.
- the slave waits for the reception of a DISCOVER packet sent by the master (S121). If the slave does not receive such a DISCOVER packet during its waiting time, it continues its scan in a next slave beam direction in step S122. If the slave receives a DISCOVER packet during the waiting time, it responds with a HEREIAM packet in step S123.
- This HEREIAM packet may include, among other things, an assessment of the receive signal quality of the DISCOVER packet (eg, RSSI) and the selected transmit direction. If the selected transmission direction is transmitted from the slave to the master M, then it is possible for him to determine the current position of the slave in the scan algorithm. It should be mentioned that the names of the packet types used are only examples. Of course, other names can also be used. Besides the use of DISCOVER and HEREIAM package types, the use of other types of packages is also within the scope of the invention. The packages may also have other functions or contain other parameters as well.
- step S1 14 a signal to initiate a second phase to the slave.
- This signal may contain a simple control packet for confirming the coarse alignment, but it may also be a more extensive handshake protocol between master and slave exchanged.
- the slave Upon receipt of the second phase initiation signal in step S124, the slave also switches to the second phase. In the second phase, a fast iterative search of further connection possibilities controlled by the master M takes place in the remaining beam combination possibilities. For this purpose, the master M gives the slave at the beginning of an iteration in step S1 15 a slave control beam direction, as well as another, until now not tested slave beam direction and the time, in which the slave should receive in this direction.
- step S1 15 the master determines a master control beam direction.
- step S125 the slave receives the information of the master.
- step S126 the slave then dwells in the specified slave beam direction until the dwell time has expired.
- step S116 the master sends DISCOVER packets in a predetermined number of its master beam directions without waiting for a response. This considerably speeds up the run for testing the beam combination possibilities.
- the slave also stores parameters of the received packets in step S126, e.g. B. the used beam direction of the master and parameters for signal quality assessment, such. B. an indicator for the reception power, such. For example, the RSSI value (Received Signal Strength Indicator).
- the master sets the master control beam direction after passing through the predetermined number of master beam directions in step S1 17.
- the slave sets the slave control beam direction (S127) and now transmits to the master the parameters of the received packets as well as the parameters for signal quality evaluation.
- the master iteratively continues the evaluation at step S1 15 with the transmission of the previous or a new beam direction for the controller, as well as a new slave beam direction for the slave, until a predetermined number of beam combinations have been tested.
- the master evaluates the parameters received from the slave and thus determines an optimal alignment of slave and master.
- Optimal alignment means guaranteeing the best possible signal quality, whereby the signal quality is evaluated, for example, with the received signal strength.
- a measure of the accuracy of the received signal for example the bit error rate, is additionally used. If an exchange between master and slave fails in the course of the procedure or a timeout occurs when returning to the predetermined control beam direction, ie no packet from the other station arrives within a specified waiting time, then in one embodiment the station can automatically return to the first phase , In this case, it advantageously selects a beam direction which corresponds to the last-used beam direction or one of the last-used adjacent and previously successfully tested beam directions. This procedure can be used to ensure that the connection search starts again with a beam direction in the vicinity of which a connection was already possible. This also leads to an acceleration of the method, for example compared to a restart with the coarse alignment.
- the master transmits at the beginning of the first phase with its maximum transmission power in order to also detect such stations. be able to reach those who are at a maximum distance to him. If an overload of the receiver's receive amplifier occurs due to the maximum transmission power of the master, then the incoming packet can generally not be decoded without error. In the prior art, no evaluation of the information contained and no handshake implementation is then possible.
- a connection can be established by both stations performing a time measurement of the incoming signal when receiving an overdriven signal. If an overdriven signal is received, the received power during the packet reception is at or near the maximum level.
- the receiving station By measuring the duration of the overdrive and comparing the duration of the overdriven signal with a desired duration of an expected signal, the receiving station, e.g. B. the slave, determine that it is probably z. B. is a DISCOVER package. If the slave can conclude that it has received a DISCOVER packet, it will in turn send a HEREIAM packet. In a preferred embodiment of the method, this HEREIAM packet is also overridden at the master. For its part, the master can carry out a time measurement of the overdriven signal as well as a comparison with the desired duration of an expected signal and thus conclude that a HEREIAM packet has been received.
- the master can determine a new transmission power, which is reduced compared to the previous transmission power and send with this reduced transmission power another DISCOVER packet.
- the respective station can adjust its latency in the current cycle accordingly, ie, the station extends its latency by the duration of the overdriven packet. This process is repeated iteratively until either a successive reduction in performance allows a faultless exchange of DISCOVER and HEREIAM packets or until a timeout expires, since no more packets arrive. In the latter case, the two stations continue with the first phase of the procedure. In the former, the master sends the signal to initiate the second phase. If the slave can decode this, the procedure continues in the second phase as described above.
- the slave if the master has sent a signal to the slave after the faultless exchange of DISCOVER and HEREIAM packets that it can not decode, the slave resets its slave beam direction by one position and remains in the first phase, ie it does not save any Parameters of incoming signals and also does not send anything to the master. The master then notices after the first iteration of the second phase that it is not receiving any signal from the slave in the master control beam direction. Then he sets his transmission power back to the maximum and starts again with the first phase.

- the master After the sending that of the DISCOVER packet, the master does not dwell in the first master beam direction to await a response, but aligns with a next master beam direction in step MS203 unless it has already used a predetermined number of master beam directions (n ). If the master has passed through all the prescribed master beam directions (y), it orients itself to a previously determined master control beam direction (MS204).
- the master sends a query packet to the slave for transmission of results of a signal quality parameter determination of the slave. The master can also simply wait for the receipt of a packet from the slave containing this information. If the master has not received the information from the slave, the master restarts phase 1 with step MS206.
- the master If the master has received the information from the slave (y), the master starts a query in step MS207 whether a predetermined number of beam combinations has been tested. If this is not the case, then in step MS208 the master sends a slave control beam direction as well as a new slave beam direction and a dwell time in which the slave is to stay in this slave beam direction to the slave and thus starts the iteration again at step MS201. If all predetermined beam combinations are tested (y), the master evaluates the results of the signal quality parameter determination transmitted by the slave in step MS209. For this purpose, in a step MS209a the master can first sort the tested beam combinations on the basis of the results of the signal quality parameter determination (eg RSSI) and send slave beam directions selected with the slave to the priority of the respective beam direction.
- the signal quality parameter determination eg RSSI
- step MS209b the master can then, in exchange with the slave, evaluate the selected beam combinations iteratively and with a bidirectional measurement of further signal quality parameters, eg the bit error rate or the packet error rate.
- the evaluation of the bit / packet error rate with approximately 1000 packets per beam direction advantageously takes place.
- step MS209c the master can then select the optimal beam combination from the evaluation and transmit it to the slave with a handshake protocol. If the handshake was successful (y), the antennas are aligned accordingly and the procedure is completed (MS210). If the handshake was not successful (n), then in step MS21 1 the master beam direction is discarded and if no further suitable beam combinations are available (y), phase 1 is restarted MS212.
- FIG. 4 schematically shows an operation method for a slave transceiver according to the fourth aspect of the invention.
- the operating procedure begins with a first Phase P1.
- step SS101 the slave is initialized at a first beam position.
- step S102 in this slave beam-beam direction, the slave waits a predetermined waiting time to receive a DISCOVER packet of a master. The waiting time of the slave is longer than a waiting time of the master.
- the slave If the slave has not received a DISCOVER packet from a master within the waiting time, it sets a next slave beam direction in step SS103 and again waits for the reception of a DISCOVER packet in step SS102. If the slave has received a DISCOVER packet (y), it sends in step SS104 a response signal to the master from which it received the DISCOVER packet. With the response signal, the slave can optionally also send to the master information about the signal quality parameters of the receiving packet as well as about its current slave beam direction. If the slave has not received a first phase DISCOVER packet but a second phase DISCOVER packet, it proceeds to step SS203, in which case the DISCOVER packet additionally includes a slave control beam direction.
- step SS105 after sending a response signal to the master in step SS104, the slave waits to receive a start signal for the second phase P2 or to exceed a predetermined time for a timeout. If the slave has not received a start signal for the second phase (n), it resets its slave beam direction by one position in step SS106 and restarts with step SS102. If the slave has received from the master a start signal for the second phase P2 (y), the slave starts the second phase by switching over to the slave beam direction transmitted by the master at the initiation of the second phase in step SS201. In step SS202, the slave stores all received packets as well as the results of signal quality parameter determinations of the received packets.
- step SS202 the slave proceeds to step SS202 until the time has elapsed (y). After the dwell time has elapsed, the slave switches to the slave control beam direction transmitted by the master in step SS203. There, in step SS204, the slave may optionally wait for the reception of a polling packet from the master, and after having received it (y), proceed to step SS206. If the slave does not receive a polling packet from the master in step SS204, the slave will reset its beam direction by one position in step SS205 and begin again with step SS102 of the first phase.
- step SS206 the slave sends the results of the signal quality parameter determinations and optionally further information about the received packets to the master.
- Step SS206 may either be following a waiting time of the slave in step SS204 for a query packet of the master, or the transmission of the information in step SS206 is effected after the expiration of the dwell time.
- step SS207 the slave may turn to a control signal of the master or the master Waiting for a timeout period to expire. If the slave does not receive a packet of the master (s) during the timeout period, the slave continues to step SS205. However, if the slave has received a packet from the master, it evaluates this in step SS208.
- step SS210 the slave can receive the optimal alignment from the master and secure it via a handshake protocol.
- step SS209 the slave may perform an iterative evaluation of beam combina- tions determined by the master together with the master. If the handshake has been successfully performed (y) in step SS210, the antennas are aligned accordingly and the process is completed (SS21 1).
- step SS212 If the handshake is unsuccessful, the slave beam direction is rejected as inappropriate (SS212) and, if no further beam combinations have been identified as appropriate, phase P1 is restarted in step SS213. If further suitable beam combinations have been identified by the master, then a next beam combination is selected by the master and with a handshake to the slave the beam combination and the slave beam direction are passed in step SS210.
