The below introduces the method for interferometry in the disclosed wireless network embodiment illustrated in fig. 5 in detail.Referenced in schematic, concrete steps are as follows:
Step 501, RRC send Sounding_REQ message to BS1 and BS2.Carry initial frame number Start Frame Number in the described interception request (diagram Sounding_REQ message), and the measure the item indication.Concrete, in the present embodiment, described measure the item indication can be audit area specific carriers interference-to-noise ratio request Sounding Zone-specific CINR request (CINR, carrier-to-interference-and-noise ratio, the carrier-in-interference noise ratio), and/or the specific received signal strength indicator request of audit area Sounding Zone-specific RSSI request (RSSI, receivesignal strength indicator, received signal strength indicator).Optionally, the indication of described monitoring project can also comprise uplink signal-channel quality information measurement type indication Type of UL CQI Measurement (UL, Up link, up; CQI, Channel Quality Information, channel quality information).Described Type of UL CQI Measurement is used to indicate the type that needs the subsidiary uplink signal-channel quality information of measuring in the interferometry process.Optionally, can also carry the site information vector of station of the website that needs transmission monitoring signal sounding signals in the described interception request, described site information can be the information of MS1, MS2 and MS3.Optionally, in a further advantageous embodiment, described RRC can also periodically carry out interferometry to require described BS1 and BS2 by carry monitor report cycle Sounding ReportPeriod in described Sounding_REQ message, and the reporting measurement result.Described RRC can be to send simultaneously to described BS1 and described BS2 transmission Sounding_REQ message, also can not send simultaneously.Do not send simultaneously, need to guarantee that all MS that participate in this interferometry can initiate the Sounding process simultaneously according to the initial frame number in the described interception request, carry out interferometry.
Step 502, BS1 send report request REP-REQ (Report Request) message to MS1, BS2 sends REP-REQ message to MS2 and MS3, carry the information of carrying in the message of Sounding_REQ described in the step 501 in the described REP-REQ message, notify each MS to send the Sounding signal at specific audit area SoundingZone.Described Sounding Zone is a time-frequency region.Described BS1 is to MS1, and it can be simultaneously that BS2 sends described REP-REQ message to MS2 and MS3, also can be asynchronous.Do not send simultaneously, need to guarantee that described MS1, MS2 and MS3 can be according to the initial frame number in the described interception request, execution in step 503 is carried out interferometry simultaneously.Described BS1 and BS2 determine which MS to send described report request to according to the site information vector of stations in the described interception request.If do not comprise described site information vector of stations in the described interception request, described BS1 and BS2 determine to participate in the MS of this interferometry in also can own MS from coverage, and send described report request to them.Described BS1 and BS2 also can be outside the MS that the site information of described interception request is indicated, and the MS that increases voluntarily in the coverage participates in this interferometry, and to the MS of described indication and the MS of increase described report request occurs all.
Step 503, described MS1, MS2 and MS3 simultaneously, with same frequency, send Sounding Signals to the BS that can communicate by letter separately according to described initial frame number Start Frame Number in sounding zone.The described BS that can communicate by letter comprises that not only it accesses the BS of the service of obtaining, and also comprises the non-serving BS broadcasts that it can be communicated by letter.Take MS2 as example, its serving BS broadcasts is BS2, but because its intersection area for the coverage of BS1 and BS2, so BS1 also can receive the signal of its transmission, and at this moment, the Sounding Signals that described MS2 sends also sends to described BS1.Comprise parameter information corresponding to monitoring project indication in the REQ of Sounding described in the step 501 message among the described Sounding Signals, calculate measurement result corresponding to described monitoring project indication for described BS1 and BS2.
Step 504, described BS1 and described BS2 are according to described Sounding Signals computation and measurement result, concrete, it can be the specific received signal strength indicator of audit area specific carriers interference-to-noise ratio and/or audit area, step 501 indicating will be measured uplink signal-channel quality information, here also comprise uplink signal-channel quality information, and the measurement result that calculates is carried at sends to described RRC in the Sounding_RSP message.In this step, optional, if fail to finish response measurement result's calculating, then carry the indication Failure Indication that makes mistakes in the described Sounding_RSP message, to make mistakes to described RRC report executing.Similar with step 501, described Sounding_RSP message can be to send to simultaneously described RRC from different BS, also can not send simultaneously.
Optionally, optimize among the embodiment at one, if carry monitor report cycle Sounding Report Period in the Sounding_REQ message in the step 501, then the described REP-REQ message in the step 502 is also carried described monitor report cycle Sounding Report Period.Described MS1, MS2 and MS3 are from described initial frame number, according to indicated cycle in described monitor report cycle, execution in step 503.After the each execution of step 503, step 504 order is carried out, and optional, step 505 also can be carried out.
The transmission path of Sounding_REQ and Sounding_RSP message can be with reference to the associated description of step 401 and step 403 among the figure 4 described embodiment in step 501 and the step 504.Repeat no more herein.The transmission path of Sounding_ACK message is consistent with Sounding_REQ message in the step 501 in the step 505, repeats no more herein.
Described Sounding_REQ, Sounding_RSP and Sounding_ACK message can be the special message according to WiMAX signaling protocol or RADIUS (Remote Authentication Dial in User Service, remote subscriber is dialled in authentication business) agreement or the new definition of Diameter.Concrete, should be such as the parameters that comprises of previous embodiment description in described Sounding_REQ and the Sounding_RSP message.Other parts can with reference to the message component part indication of described agreement, repeat no more herein.
By using the described method of above-described embodiment, RRC can be by carrying initial frame number in Sounding_REQ message, indication BS1 and BS2 carry out interferometry simultaneously, by in Sounding_REQ message, carrying the specific received signal strength indicator request of the interference-to-noise ratio request of audit area specific carriers or audit area, indicate each BS to carry out the project of interferometry, and after measuring end, receive the measurement result that each BS reports.Further, can also carry uplink signal-channel quality information measurement type indication Type of UL CQI Measurement in the described Sounding_REQ message, with the additional uplink signal-channel quality information of measuring in described interferometry process.Further, monitor report cycle Sounding Report Period be can also carry in the described Sounding_REQ message, interferometry and reporting measurement result periodically carried out to indicate.Make mistakes if measure, can also report the indication that makes mistakes.Further, described RRC can also issue sub-carrier distribution manner and the transmitting power of suggestion according to the measurement result that reports by Sounding_ACK message, realizes striding the low interference optimization configuration of BS.
Along with the development of wireless access technology, a kind of wireless access technology that is called relaying technique begins should be used on a large scale.Relaying technique claims again Relay, also claims the multi-hop technology, is so that wireless signal can be through repeatedly transmitting a kind of transmission technology that (multi-hop) arrives the destination.In the wireless transmission net, the relaying technique network architecture partly is comprised of three basic as shown in Figure 6:
(1) MRBS (Multihop Relay Base Station, multi-hop relay base station): a kind of for relay station is connected connection with user terminal, the equipment of management and control.
(2) RS (Relay Station, relay station): a kind of MRBS that depends on, the equipment of connection is provided for other RS or user terminal, be the transfer website of data between base station and the terminal.Some RS also can provide management and control for subordinate RS or user terminal.Between RS and SS eat dishes without rice or wine with MRBS and SS between to eat dishes without rice or wine be identical.
(3) SS/MS (Subscriber Station/Mobile Station, user terminal/portable terminal): generally be called for short terminal, the user uses this equipment access Radio Access Network.
In existing relay system, the safe mode of relay station has two kinds: centralized safety and distributed security.Centralized safety refers to that RS is without any the key information relevant with MS or the RS of subordinate (key that is used for data with the integrality that guarantees administrative messag of encrypted transmission), so it transfers non-decrypting user data or checking MAC administrative messag with in simple only.Its security association is based upon between MS or the RS of subordinate and the MRBS, perhaps is based upon between MS or the RS of subordinate and the higher level RS.Distributed security refers to that RS preserves the key information of its subordinate MS, and the key between RS and MS is different from the key between RS and MRBS.RS need to the message received or data be decrypted and re-encrypted.(distributed security is only different to the key information between the MRBS from access RS to the key information of access RS for MS, does not have the different situation of key information between several RS.)
After relaying technique introduced WiMAX, because the relay station access base station, the disturbed condition of base station cell was more complicated.Introduce relaying technique in the WiMAX system after, BS becomes the multi-hop relay base station MRBS that can support relaying technique, and RS accesses MRBS, and MS is by the RS access network, perhaps directly by the MRBS access network.Under this scene, the deployment of RRC and RRA can have three kinds of modes, respectively as shown in Figure 7.
