Embodiment
In order to make concrete technical scheme of the present invention, goal of the invention clearer, be described further below in conjunction with concrete execution mode and accompanying drawing.
In embodiment of the present invention, terminal can be according to each relay station of relay station sign identification, terminal is used to report the ascending resource of downlink channel measurement information to base station requests, after obtaining the ascending resource of base station assigns, give the base station with reporting downlink channel measurement information, thereby can improve the base station to descending scheduling and efficiency of resource distribution so that the base station obtains the down channel quality of relay station exactly.With reference to Fig. 1, embodiment of the present invention provides a kind of method for reporting downlink channel measurement information, comprising:
Step 101: obtain the relay station sign, discern relay station according to relay station;
Step 102: measure the down channel of each relay station of identification, send resource request message to the base station;
Step 103: the ascending resource according to base station transmitting terminal resource allocation message appointment sends to the base station with down-run survey information.
With reference to Fig. 2, introduce first embodiment of the invention, about a kind of method for reporting downlink channel measurement information, in the present embodiment, terminal is in normal course of communications, the down channel quality of detection trigger relay station when unusual appears in the channel quality that runs into service relay stations, and measured descending channel information is reported the base station.
Step 201: obtain the relay station sign, and discern relay station according to relay station;
The method that terminal is obtained the relay station sign can obtain for indicating by the base station, and perhaps terminal is stored in advance.
The base station can make terminal can discern relay station by broadcast channel or control channel explicitly or impliedly to terminal indication relay station sign, guarantees that terminal does not produce between to relay station or base station when measuring and obscures carrying out down channel.In transparent scene, terminal can directly receive the relay station sign that the base station sends, in nontransparent scene, the relay station sign that the base station sends is transmitted to terminal by relay station, when transmitting, can transmit, also can transmit by each relay station by a relay station of current service by relay station, when each relay station is transmitted, promptly be equivalent to relay station and in broadcast, send the relay station sign.In the accompanying drawings, the step of dotted line sign is arranged side by side with the step of solid line, when carrying out some steps, can select a kind of method step to carry out flow process according to actual conditions.
The method of explicit indication relay station is the base station with the coding of different relay stations in the base station cell, and perhaps the pilot frequency sequence or the pilot frequency sequence corresponding codes of different relay stations sends to terminal in the network.The frequency resource of the relay station of the frequency resource that the relay station in a sector or wave beam uses and another sector or wave beam is overlapping, can be referred to as the relay station that the space can be discerned in the sub-district, or the non-overlapping relay station in space, in this case, can encode to relay station, as when having three relay stations, can adopt 2 bits 01,10 and 11 represent relay station 1 respectively, relay station 2 and relay station 3, coding can be participated in the base station, also can not participate in coding, when coding is participated in the base station, such as can 00 representing the base station, do not participate in when coding when the base station, then not being identified as the frequency range of relay station pairing is exactly the frequency range of base station.When the shared running time-frequency resource of each relay station has when overlapping, be to have on the space when overlapping, also may there be the overlapping situation of running time-frequency resource between base station and the relay station, in this case, can discern relay station by the superpose method of code word of pilot tone, corresponding base station of each pilot frequency sequence and/or relay station, i.e. also corresponding base station of each coding and/or relay station.Part or all of when overlapping when base station and relay station running time-frequency resource, relay station can adopt the superimposed code different with the base station on pilot tone; When partly or entirely running time-frequency resource is overlapping between the relay station, use different pilot tone superimposed codes between the relay station; Superimposed code can be pseudo random sequence, orthogonal sequence and CAZAC sequence etc., or the identify label of each relay station, as relay station ID or relay station coding or synchronizing signal etc., when existing running time-frequency resource overlapping between relay station or the base station, the base station is informed the superimposed code corresponding codes of each relay station pilot tone use of terminal or is carried out coherent detection by terminal according to the pilot frequency sequence of storing in advance by broadcast channel or control channel, owing to used different superimposed codes on the relay station pilot tone, terminal is carrying out can discerning each relay station when down channel is measured.
The method of implicit indication relay station is that terminal is not informed with the relay station coding in the base station, but terminal is informed in the pairing running time-frequency resource of each relay station position, because being relay station, the base station distributed different running time-frequency resources, different relay stations can use nonoverlapping running time-frequency resource, therefore, as long as terminal has been measured the channel quality on the corresponding running time-frequency resource, then terminal just can identify concrete relay station.
Terminal also can be stored the relay station sign in advance, and the relay station sign of storage can be the pilot frequency sequence or the pilot frequency sequence corresponding codes of different relay stations.
Step 202: terminal is measured the down channel of base station and each relay station and is measured, and selects relay station to carry out resource request;
Terminal with the down channel quality of each service relay stations and thresholding interval [D1, U1] (U1 〉=D1) compare, select down channel quality not at this interval relay station; For non-service relay stations, select channel quality in the non-service relay stations to be higher than the relay station of certain threshold value, this threshold value can be D1, or threshold value that relative value obtains of D1 stack.The thresholding interval value can be informed terminal by base station or relay station.When selecting service relay stations, the service relay stations that also can the selective channel quality be higher than the interval higher limit of thresholding, if when having other service relay stations channel quality to be lower than this threshold value, whether select this service relay stations that is lower than threshold value to report according to the relay station number decision of having selected, because the message resource of resource request may be limited, such as having only 2bit, can only represent 4 relay stations, there are 2 service relay stations channel qualities to be higher than the interval upper limit of thresholding now, lower limit between 1 below threshold region is arranged.At this moment, there are 2 non-service relay stations to be higher than the interval lower limit of thresholding.So at this moment, may only select 2 non-service relay stations being higher than 2 service relay stations of the interval upper limit of thresholding and being higher than the interval lower limit of thresholding, and not select the service relay stations of lower limit between below threshold region.
Step 203: send resource request message to the base station;
For selected relay station, can be all relay station request resource, but consider saving system resource, also can be the relay station request resource of all selections, but can send resource request for several relay stations by the base station designated terminal, terminal sorts the relay station of selecting according to down channel quality, according to the preferential selective channel quality of the number of appointment preferably relay station carry out resource request.
If the down channel quality of base station is higher than a threshold T 2, threshold T 2 can be informed terminal by base station or relay station, the down channel quality of base station is higher than T2, illustrate that then the link-quality between terminal and the base station is good, communication quality between can guaranteeing, then terminal can directly send to the base station with resource request, the explicit or sign of impliedly carrying the best relay station of channel quality in sending to the resource request message of base station, and the sign of relay station number or each relay station.
If the down channel quality of base station is lower than threshold T 2, then terminal sends to the best relay station of channel quality with resource request message, this relay station is transmitted to the base station with this resource request message, and this resource request message can comprise the number that reports relay station or the sign of each relay station.
Step 204: ascending resource is distributed in the base station after receiving resource request message;
The base station is according to received resource request message, distributes ascending resource, finish distribution after, resource allocation message is sent to terminal, can comprise running time-frequency resource position and/or the used code word and/or the relay station sign etc. of use in this resource allocation message.If the received resource request message in base station is that terminal directly sends, then the base station will distribute the resource allocation message of ascending resource directly to send to terminal.
Best relay station is transmitted if the received resource request message in base station is a down channel quality, and then the base station sends to this relay station with resource allocation message, and this relay station is transmitted to terminal with resource allocation message.
Step 205: terminal sends to the base station with downlink channel measurement information;
Terminal directly sends to the base station with downlink channel measurement information after receiving assignment messages, perhaps send to the best relay station of down channel quality, and is transmitted to the base station by this relay station.
Comprise channel quality measurements in this channel quality measurement message to each relay station of having selected, and the indication of the pairing relay station of measurement result, this indication can be explicit or implicit mode.
So far, finished terminal reporting to measured descending channel information.The base station is after receiving the downlink channel measurement information of terminal to report, according to the cooperating relay station of down channel quality decision to the service of terminal, the relay station of perhaps selecting the down channel quality excellence is separately as the service relay stations of terminal, selected relay station is informed terminal, and terminal is finished at the resident of relay station or is switched.
The technical scheme that embodiment of the present invention provides is applicable to dual-modes such as TDD, FDD, and the situation at various cooperating relay station and non-cooperating relay station.
The technical scheme that provides according to present embodiment, relay station is indicated and informed terminal or detect according to the relay station sign of storage by the base station and discern relay station by terminal, make terminal can identify each relay station, report downlink channel measurement information, improved the base station and carried out descending scheduling and efficiency of resource distribution each relay station.Further, select directly or by the best relay station of down channel quality, terminal sends resource request message, guaranteed the reliability of resource request message according to the base station down channel quality condition; Terminal is according to the channel quality of the relay station of measuring and the comparison of the threshold value of being scheduled to, select suitable relay station, can comprise the non-preferably service relay stations of link-quality, reduced the delay of terminal to report, also reduced the delay that non-service relay stations is a Terminal Service non-service relay stations channel quality.
