In embodiments of the present invention, terminal can initiatively trigger the flow process of step 1, that is, terminal when networking, trigger or, terminal triggers according to the needs of self.Also can be after terminal network by the base station, trigger the flow process of step 1 according to the demand of the demand of base station and/or terminal.Can also be in the CQI of embodiment of the invention feedback information process, terminal and/base station periodically triggers the flow process of step 1 change so that adapt to real-time carrier wave.

In embodiments of the present invention, after step 2, the base station can send to terminal with being used to feed back the organizational form of resource, this resource of CQI information and the original position of distributing to the resource of terminal in the carrier wave, so that the CQI information that terminal will need to feed back is fed back with this resource.This resource that is used to feed back CQI information can be used as CQICH (Channel Quality Indicator Channel, the channel quality indicating channel) resource area, the base station can be a plurality of Resource Block according to the basic granularity division that sets in advance with this resource, the Resource Block connective tissue of same terminal will be distributed to, like this, the original position that terminal receives is a call number, the number of carriers that terminal is fed back CQI information as required draws the resource that is used to feed back CQI that base station assigns is given this terminal, and according to call number and the resource that draws the CQI information that needs feed back is fed back to the base station with this resource.Under the situation of this resource according to Tree (tree-like) tissue or Bitmap (bit map) tissue, the original position that terminal receives is a node number, and terminal feeds back to base station with the CQI information that needs feed back with described resource according to this node number.

Method to the embodiment of the invention is described in detail below.Second embodiment of the present invention comprises:

Process one: terminal and base station negotiate need be fed back the carrier wave of CQI information, promptly determine the carrier subset that to feed back CQI information, the carrier subset of feeding back CQI should be a subclass of all carrier wave collection, promptly may be the whole or portion of carriers of all carrier waves.In embodiments of the present invention, the first carrier subclass and the carrier wave in second carrier subset that need to determine overlap, and need broadband CQI information and all subband CQI information of these carrier waves of feedback,

In the process of terminal and base station negotiate, can initiate to consult flow process by terminal, promptly CQI feedback carrier subclass is as shown in Figure 2 consulted flow process, can send the message that request determines to feed back the carrier subset of CQI information to the base station by terminal, after the base station receives this message, determine to feed back the carrier subset of CQI information, and send the message that response determines to feed back the carrier subset of CQI information to terminal.Also can initiate to consult flow process by the base station, similar with method shown in Figure 2, send the message that request determines to feed back the carrier subset of CQI information by the base station to terminal, after terminal receives this message, determine to feed back the carrier subset of CQI information, and send the message that response determines to feed back the carrier subset of CQI information to the base station.

Consult in the flow process in CQI feedback carrier subclass shown in Figure 2, request need to be determined can comprise in the message of carrier subset of feedback CQI information: carrier information; Perhaps, the CQI information of carrier information and carrier wave; Perhaps, carrier information and time period information; Perhaps, the CQI information of carrier information, carrier wave and time period information.Can comprise in the message of the carrier subset of the definite needs feedback of response CQI information: at least one information in indication information, carrier information and the time period information.This indication information can be for agreeing or disagree with the indication of the other side's request, such as " OK ".This carrier information can comprise: at least one information in the bandwidth of the centre frequency of carrier wave, the index information of carrier wave, carrier wave.

In embodiments of the present invention, also can determine carrier subset, and send the message of the carrier subset of determining to the opposite end by terminal or base station.Can comprise in this message: carrier information; Perhaps, the CQI information of carrier information and carrier wave; Perhaps, carrier information and time period information; Perhaps, the CQI information of carrier information, carrier wave and time period information.

In embodiments of the present invention, no matter be need to determine the carrier subset of feedback CQI information, all can determine in the following way: determine carrier subset according in the service conditions of the carrier wave tenability of the loading condition of the channel quality information of at least one carrier wave, at least one carrier wave, terminal, terminal at least one by the base station or by terminal.Determine that with the base station needing the carrier subset of feedback CQI information is that example is described in detail this deterministic process below.This channel quality information comprises: at least one broadband CQI information; And/or, at least one subband CQI information.

The base station determines that the method that need feed back the carrier subset of CQI information comprises:

Mode one: terminal is fed back the CQI information of all carrier waves, comprise broadband CQI and/or subband CQI information, the base station according to receive once or this terminal repeatedly about the CQI information of all carrier waves (under situation repeatedly, the CQI information of base station statistics a period of time), select one or more wherein best carrier wave as the carrier wave collection that will feed back CQI.

Mode two: a CQI feedback carrier subclass directly according to the loading condition of each carrier wave, is selected to terminal in the base station.

Mode three: the base station is selected a CQI feedback carrier subclass according to the carrier wave tenability of terminal to terminal.Support 5 carrier waves such as the base station, terminal is supported 3 carrier waves, and the base station then will select 3 carrier waves as CQI feedback carrier subclass for terminal.

Mode four: the base station is according to the service conditions of terminal, promptly come to select a CQI feedback carrier subclass to terminal according to the transmitted data amount size of terminal, such as having only a Best-Effort service (Besteffort service) when terminal, and bandwidth requirement is not high, in this situation, only carrier wave of needs just is enough to the transmission needs of support terminal, so the CQI feedback carrier subclass of a carrier wave as terminal will be selected in the base station.

When specific implementation, the base station can be taken all factors into consideration according in four kinds of methods listing above one or more, with the CQI feedback carrier subclass of decision terminal.Such as:

Comprehensive example one: 5 carrier waves are supported in the base station, and the carrier wave tenability of terminal is to support 3 carrier waves, the base station can select 3 best carrier waves of the CQI of terminal feedback as the carrier subset that will feed back CQI, can certainly be further according to the service conditions of terminal, want data quantity transmitted seldom such as current terminal, only need a carrier wave with regard under enough situations, the base station can only select a best carrier wave of CQI as the carrier subset that will feed back CQI.

Comprehensive example two: the base station is when determining to feed back the carrier wave collection of CQI for terminal, to take into account the CQI and the loading condition of carrier wave simultaneously, the weight that can be CQI according to the situation of network side when specific implementation different with the load design then relatively the weight after the CQI+ load of each carrier wave can calculate the priority level of each carrier wave, thereby filter out the carrier wave collection that will feed back CQI.In like manner, to feed back on the basis of carrier wave collection of CQI at this and can further dwindle or enlarge CQI feedback carrier subclass according to the service conditions of the carrier wave tenability of terminal and terminal.

Process two: that can condition trigger terminal and base station or periodically redefine CQI feedback carrier subclass.Such as when terminal networks, just can condition triggering the operating process of determining CQI feedback carrier subclass, after determining this carrier subset, triggering that can the cycle in time of back redefines the operating process of CQI feedback carrier subclass, all is with the present case coupling to guarantee carrier wave that CQI feedback carrier subclass is selected.During realization, a message interaction process be can between terminal and base station, increase, the trigger condition and the cycle of flow process consulted to confirm this.Also can directly trigger this process by the unconditional message interaction process of initiatively initiating of terminal or base station, this also can be regarded as the negotiation flow process that condition triggers in essence certainly.Like this, before the process one of the embodiment of the invention or the carrying out in the process of process one, can also comprise process two, promptly be used for determining the trigger condition of CQI feedback carrier subclass negotiation flow process and the message interaction process in the cycle of triggering, initiating by terminal under the situation of trigger condition, as shown in Figure 3, comprising:

Step 1: terminal request CQI feedback carrier subclass is consulted the trigger condition of flow process and/or is triggered periodic messages.Can comprise in this request message: needs are determined the carrier information in the trigger condition and/or the cycle of triggering; Perhaps can also comprise: the trigger condition of request and/or triggering cycle.

Step 2: the base station is confirmed the trigger condition of CQI feedback carrier subclass negotiation flow process and/or is triggered periodic messages.Can comprise in this acknowledge message: the trigger condition of determining and/or the carrier information in the cycle of triggering; Perhaps can also comprise: trigger condition and/or the triggering cycle determined.

This carrier information can comprise: at least one information in the bandwidth of the centre frequency of carrier wave, the index information of carrier wave, carrier wave.

Like this, the feedback carrier subclass is consulted the trigger condition of flow process and the message interaction process in cycle finishes, and terminal triggers the negotiation flow process according to trigger condition or triggering cycle, that is, execution in step 3:CQI feedback carrier subclass is consulted flow process.

The direction of step 1 in the present embodiment and step 2 can change, be that request message in the step 1 can be issued terminal by the base station, also can issue the base station by terminal, the affirmation message in the step 2 can be issued the base station by terminal, also can issue terminal by the base station.

Terminal or base station also can directly be determined or be changed trigger condition and/or triggering cycle, and with carrier information, trigger condition and at least one the notice opposite end in the triggering cycle of determining; Described carrier information comprises: at least one information in the bandwidth of the centre frequency of carrier wave, the index information of carrier wave, carrier wave.

Message interaction process also can initiatively be initiated in terminal or base station, directly triggers process that CQI feedback carrier subclass consults flow process as shown in Figure 4, comprising:

Step 1: terminal request is carried out CQI feedback carrier subclass and is consulted flow operations.

Step 2: CQI feedback carrier subclass negotiation flow operations is confirmed in the base station.

Like this, the message interaction process that triggers CQI feedback carrier subclass negotiation flow process finishes, and terminal triggers the negotiation flow process according to trigger condition or triggering cycle, that is, execution in step 3:CQI feedback carrier subclass is consulted flow process.

Further, the CQI feedback cycle of each carrier wave of terminal correspondence can be adjusted according to the transfer of data situation.This CQI feedback cycle can be determined when terminal networks, also can the time in the process of feedback CQI information, determine, such as: after terminal networks, terminal has only a business, volume of transmitted data is very little, the CQI feedback cycle of the main carrier of terminal correspondence keeps a stable cycle at this moment, such as 5 milliseconds, the CQI feedback cycle of other carrier wave is consulted to be revised as 20 milliseconds by the message of terminal and base station, when terminal is set up more Business Stream, when causing data quantity transmitted to increase, terminal and base station consult the CQI feedback cycle of other carrier waves is revised as 10 milliseconds or 5 milliseconds by message so, the base station just can learn that this terminal gets channel quality condition at other carrier waves like this, can be in the enterprising line data scheduling of these carrier waves.As shown in Figure 5, the process of the CQI feedback cycle of this negotiation adjustment carrier wave comprises:

Step 1: the base station sends a request message to terminal, comprising: carrier information (such as: at least one information in the bandwidth of the centre frequency of the carrier wave of request, index and carrier wave), the request the CQI feedback cycle.

Step 2: terminal sends acknowledge message to the base station, comprising: and carrier information (such as: at least one in the bandwidth of the centre frequency of the carrier wave of request, index and carrier wave), the CQI feedback cycle confirmed.

Like this, the message interaction process of consulting the CQI feedback cycle of modification carrier wave finishes, and terminal triggers the CQI feedback according to the amended cycle.

The direction of message can change in this step 1 and the step 2, and promptly the request message in the step 1 can be issued terminal by the base station, also can issue the base station by terminal, and the affirmation message in the step 2 in like manner.

The CQI feedback cycle of carrier wave also can directly be revised in terminal or base station, and amended CQI feedback cycle and carrier information are sent to the opposite end.

Process three: the CQI information of the carrier wave that terminal comprises CQI feedback carrier subclass is placed on one or more carrier wave to be fed back.During specific implementation, terminal can all be placed on the CQI information of CQI feedback carrier subclass on the carrier wave (such as the main carrier of terminal correspondence for this reason) and feed back, and CQI information that also can each carrier wave is placed on separately to be fed back on the carrier wave.The CQI information of feedback comprises the details of broadband CQI and all subband CQI; And after definite CQI feedback carrier subclass, terminal will only be fed back the CQI information of the carrier wave that this carrier subset comprises, not feed back the CQI information of other carrier wave.

Like this, the terminal scheduling data can be given in the base station in the carrier wave that CQI feedback carrier subclass comprises, because the channel quality condition of this terminal on these carrier waves known in the base station, can carry out more efficiently scheduling.

Adopt present embodiment to save CQI feedback (CQI feedback) information, do not feed back CQI information for the carrier wave in feeding back CQI carrier wave collection not.

In the 3rd embodiment of the present invention, the carrier wave that the first carrier subclass comprises is all carrier waves in the multicarrier system, be the broadband CQI information that terminal need be fed back all carrier waves, second carrier subset is to determine according to the method for the carrier subset of definite needs feedback CQI information of the embodiment of the invention, comprises the steps:

Step 1: terminal is fed back the broadband CQI information of all carrier waves, and being equivalent to each carrier wave all has corresponding basic CQI channel.

Step 2: terminal and base station base station negotiate will be fed back second carrier subset of subband CQI information, that is to say to have only portion of carriers that less important CQI channel is just arranged for terminal; Second carrier subset of the needs feedback subband CQI information of terminal correspondence is a subclass of all carrier set.

How terminal and base station consult determine to need the operating process of carrier wave collection of feedback subband CQI information similar with the CQI feedback carrier subclass negotiation flow process of embodiment one, two, no longer are described in detail here.

In embodiments of the present invention, terminal and base station can condition carrier wave collection that trigger or that periodically redefine needs feedback subband CQI information.

The trigger condition and the message interaction process in cycle that definite CQI feedback carrier subclass of this operating process and embodiment two is consulted flow process are similar.

Step 3: terminal is subband CQI feedback carrier subclass, and promptly the subband CQI information of the carrier wave that comprises of second carrier subset is placed on one or more carrier wave and feeds back.During specific implementation, terminal all is placed on the CQI information of subband CQI feedback carrier subclass on the carrier wave (such as the main carrier of terminal correspondence for this reason) and feeds back, and subband CQI information that also can each carrier wave is placed on separately to be fed back on the carrier wave.

Terminal is placed on the broadband CQI information of all carrier waves on one or more carrier wave to be fed back.During specific implementation, terminal all is placed on the broadband CQI information of all carrier waves on the carrier wave (such as the main carrier of terminal correspondence for this reason) and feeds back, and broadband CQI information that also can each carrier wave is placed on separately to be fed back on the carrier wave.

In the present embodiment, the base station can be added up the broadband CQI information of all carrier waves of terminal in a period of time, carry out carrier wave according to statistics and switch (carrier switch) operation, such as subband CQI feedback carrier subclass, promptly the broadband CQI statistics of the carrier wave in second carrier subset does not have the CQI statistics of the outer carrier wave of subclass good, base station and terminal can consult to revise subband CQI feedback carrier subclass so, and guaranteeing to feed back the carrier wave that the carrier wave of Sub-band CQI concentrates all is that broadband CQI statistics is reasonable.

In the present embodiment, the base station can only be concentrated to the terminal scheduling data at the carrier wave of feedback subband CQI.

The 4th embodiment of the present invention and embodiment three are similar, different places is that present embodiment has two carrier subset, and one is the carrier subset that will feed back broadband CQI, i.e. the first carrier subclass, another is the carrier subset that will feed back subband CQI, i.e. second carrier subset.Can determine this two subclass by terminal and base station negotiate, also can determine these two subclass separately by terminal or base station.Under the situation that terminal and base station negotiate are determined, comprising:

Step 1: terminal and base station negotiate will be fed back the first carrier subclass of broadband CQI information and will feed back second carrier subset of subband CQI information.How terminal and base station consult to determine that the operating process of the first carrier subclass and second carrier subset is similar with the CQI feedback carrier subclass negotiation flow process of embodiment two.

In embodiments of the present invention, terminal and base station can condition trigger or periodically redefine the first carrier subclass and second carrier subset.The trigger condition and the message interaction process in cycle that definite carrier subset of this operating process and embodiment two is consulted flow process are similar.

Step 2: the subband CQI information of the carrier wave that terminal comprises second carrier subset is placed on one or more carrier wave to be fed back.During specific implementation, terminal all is placed on the CQI information of second carrier subset on the carrier wave (such as the main carrier of terminal correspondence for this reason) and feeds back, and subband CQI information that also can each carrier wave is placed on separately to be fed back on the carrier wave.

The broadband CQI information of the carrier wave that terminal comprises the first carrier subclass is placed on one or more carrier wave to be fed back.During specific implementation, terminal all is placed on the CQI information of first carrier subclass on the carrier wave (such as the main carrier of terminal correspondence for this reason) and feeds back, and broadband CQI information that also can each carrier wave is placed on separately to be fed back on the carrier wave.

In the present embodiment, the base station can be added up the broadband CQI information of the carrier wave that the broadband CQI feedback carrier subclass of terminal comprises in a period of time, carries out the carrier wave handover operation according to statistics.

The 5th embodiment of the present invention is on the basis of embodiment one to four, further limits the time period of the carrier wave feedback CQI information in the carrier subset of determining.Specifically can limit the time period of carrier wave feedback CQI information in the mode of time window, carrier wave in the carrier subset just feeds back CQI information in the time window of the activation of correspondence, and in nonactivated time window, can not feed back CQI information, further saved the transport overhead of CQI in this way., can learn in this patent that needing the time period of feedback CQI information is exactly the time window that activates here, and the time period that does not need to feed back CQI information is exactly nonactivated time window.

Can an activationary time window be set to carrier wave; Also can the unequal activationary time window of several length be set to carrier wave; The fixing activationary time window of a length also can be set, periodically limit the time of carrier wave feedback CQI information with this activationary time window, such as: a length be set be 5 milliseconds activationary time window, at a certain specific carriers, limit the time of this carrier wave feedback CQI information every this activationary time window of 10 milliseconds of usefulness, promptly, this carrier wave is in first 5 milliseconds of internal feedback CQI information, cross 10 milliseconds afterwards, again second 5 milliseconds internal feedback CQI information, cross 10 milliseconds afterwards, again the 3rd 5 milliseconds internal feedback CQI information, and the like.

The unit of time window can be second, millisecond, and microsecond, superframe, frame, subframe equal time unit can claim needs feedback CQI the time window of time window for activating of information, and the time window that does not need to feed back CQI information is called nonactivated time window.The schematic diagram of time window is as shown in Figure 6:

By among Fig. 6 as can be seen, suppose in a multicarrier system, for terminal, carrier wave 2 is main carriers of its correspondence, and terminal can be fed back CQI information all the time on main carrier so, but for other carrier wave, terminal can need be fed back the time window of CQI information with base station negotiate, in the time window that activates, it will feed back the CQI information of corresponding carrier wave, and this information can be transmitted by main carrier or other carrier waves.Certainly, even for main carrier, the time window of feedback CQI information need also can be consulted in terminal and base station.

And, determined to need the carrier subset of feedback CQI information by the method for the embodiment of the invention one to four after, can realize reducing the target of CQI transmission by the time window that will feed back CQI information of determining each carrier wave, if promptly do not need certain carrier wave feedback CQI, can be made as 0 by time window and realize the feedback CQI of this carrier wave.

The method of determining the activationary time window of each carrier wave can be definite by terminal or base station, and carrier information and the time period information of determining is sent to the opposite end.Also can be come in to consult by message by terminal and base station, the flow process of the activationary time window of definite each carrier wave be as shown in Figure 7 between terminal and the base station: comprising:

Step 1: terminal sends a request message, the activationary time section of each carrier wave correspondence is determined in request, can comprise in this request message: corresponding carrier information is (such as carrier index, the center frequency point of carrier wave, the bandwidth of carrier wave etc.), activationary time window information (such as the frame number of starting point, the frame number of end point; Or the frame number of starting point adds a time span, and unit is the same, starting point certainly, end point, the unit of time span also can be superframe, subframe, millisecond, microsecond equal time unit), optionally, can also comprise in this request message: the gap periods of this activationary time window information.

The 6th the resource assignment method that embodiment is a CQI channel under the multicarrier of the present invention, promptly in carrier subset that need to have determined feedback CQI information, and determined to be used to feed back after the concrete carrier wave of CQI information (promptly at embodiments of the invention one after five), be used for determining that being used on the carrier wave feed back the method for the resource of CQI information.This method comprises: the resource of CQI information, the organizational form of described resource are determined to be used in each carrier wave feed back in the base station; And the organizational form of described resource and the original position of distributing to the resource of terminal sent to terminal; Terminal is according to the described organizational form and the original position that receive, and the CQI information that needs are fed back feeds back to the base station with described resource.

Present embodiment can be used for the resource assignment method of Primary CQICH and Secondary CQICH under the multicarrier scene.According to different resource organizations's modes, specifically can adopt following two kinds of methods:

Method one:

After the base station is determined to be used in each carrier wave feed back the resource of CQI information, this resource can be used as the resource area of CQICH, is a plurality of Resource Block with this CQICH resource area by a certain basic granularity division that sets in advance, and will distribute to the Resource Block connective tissue of same terminal.Like this, the base station sends to the resource granularity call number of the original position of terminal for the beginning of the Resource Block of this connective tissue.Terminal is according to the call number that receives, draws the resource that the CQICH of a plurality of carrier waves of this terminal correspondence takies according to the number of carriers of described call number and needs feedback CQI information.

The base station informs that the resource area of terminal CQICH can also can be in advance use the resource area of fixed position as CQI channel correspondence at each frame (or superframe) by the mode of broadcasting (or multicast/clean culture).

The CQI feedback carrier of terminal can be the main carrier of terminal correspondence, and like this, the Primary CQICH of terminal correspondence and Secondary CQICH are on this carrier wave.A carrier wave can be the CQI feedback carrier of a plurality of terminals, and promptly the CQICH of a plurality of terminals is placed on the same carrier wave.Wherein PrimaryCQICH is for safeguarding basic connection reliably, it feeds back the average CQI on the whole bandwidth, bandwidth CQI just, and feedback cycle is longer relatively, the Primary CQICH feedback content of each each carrier wave of terminal (being Wideband CQI) is identical with feedback cycle, and size is consistent; Secondary CQICH is timely feedback channel state, to carry out frequency selective scheduling, the relevant scheduling of MIMO etc., thereby obtain the efficient scheduling gain, improve DL (down link, descending) systematic function, the resource size that needs the corresponding CQICH of increasing is to carry more feedback information.

Particularly, for Primary CQICH, because the size of the PrimaryCQICH of each carrier wave of same terminal is consistent with the cycle, further, even for different terminals, their Primary CQICH and cycle also should be similar to, therefore we can design a PrimaryCQI Zone (main CQICH zone), in this zone, each basic granularity is the size (can be 6bits or more) of an average CQI value (average CQI value), the Primary CQICH of a plurality of carrier waves of each terminal assignment continuously in this zone then, because the Primary CQICH's of each carrier wave is equirotal, because we can adopt the method for optimization, the base station uses unicast messages notice terminal assignments to give its beginning index (index), the P rimary CQICH quantity of the carrier wave that terminal will be fed back according to it obtains the resource of the continuous granularity that this index begins, again according to the index of the resource of the ascending order of the carrier index (carrier index) of carrier wave or the primary CQICH correspondence that descending is learnt each carrier wave.That is to say, by an index of a resource of assignment terminal, terminal and base station calculate the index (index) of the corresponding resource of each carrier wave of this terminal Primary CQICH by the rule of acquiescence then, this method has been saved the expense of a plurality of primaryCQICH of terminal of separate assignment in the multicarrier system greatly, has reached the effect of saving overhead (signaling consumption).

Fig. 8 is the schematic diagram of resource organizations's mode of employing mode one, specifically comprises:

Step 1: the resource area of fixed position as CQI channel correspondence used by position or each frame (or superframe) of the resource area of broadcasting (or multicast or clean culture) CQI channel correspondence in the base station, and this Resource Block is divided according to least resource granularity unit (can be the size of broadband CQI in specific implementation).

Step 2: the beginning index (index) of unicast messages notice terminal assignments to the resource area correspondence of its CQI channel correspondence used in the base station.

Step 3: the Primary CQICH quantity of the carrier wave that terminal will be fed back according to it obtains the resource of the continuous granularity that this index begins, again according to the index of the resource of the ascending order of the carrier index of carrier wave or the primary CQICH correspondence that descending is learnt each carrier wave.

This method can be applied among all CQICH; only the resource area of CQICH need be divided by a certain basic granularity; the CQICH resource of determining terminal its a plurality of carrier wave in this zone then is to divide continuously; the resource granularity index that begins of an assignment so; then by terminal; the base station according to the carrier case of terminal (such as the quantity of the carrier wave of feedback CQI; the carrier index of carrier wave) calculates the CQI resource that the CQICH of a plurality of carrier waves of this terminal correspondence takies; all be that the present invention wants the scope protected; in this embodiment just with primary CQICH as a specific embodiment, be not limited to the resource assignation of Primary CQICH.

Method two:

The CQI information of all carrier waves of terminal is fed back in a carrier wave, the resource area of CQICH is divided by a certain basic granularity, and the base station uses Tree (tree-like) or Tree+Bitmap (tree-like and bit map combination) mode to indicate the CQICH resource that each carrier wave distributed to each terminal.

Fig. 9 is the schematic diagram of resource organizations's mode of employing mode two, specifically comprises:

Step 1: (or multicast or clean culture) SecondaryCQICH resource area is broadcasted at each frame (or superframe) in the base station, and this Resource Block is divided according to least resource granularity unit;

Step 2: the base station is by the concrete resource location of Secondary CQICH of each carrier wave of unicast messages notice terminal; Unicast messages uses Tree or Tree+Bitmap mode to indicate concrete resource location.For example, tree node 3 (being resource 7,8) is distributed to the carrier wave 1 of terminal as the SecondaryCQICH resource, node 9 is distributed to the carrier wave 2 of terminal as Secondary CQICH, and tree node 2 (is a

resource

11,12,13,14) distribute to the carrier wave 3 of terminal as Secondary CQICH.Node 2+Bitmap (1011) represents that then

resource

11,13,14 distributes to carrier wave 3, and wherein " 1 " expression takies this resource among the Bitmap, and " 0 " expression does not take this resource.

This mode can be applied among all CQICH, main thought is that the resource area of CQICH is divided by a certain basic granularity, base station use unicast messages is indicated the CQICH resource that each carrier wave distributed to each terminal, and the indicating mode of resource uses Tree or Tree+Bitmap.The CQICH resource adopts Tree or Tree+Bitmap mode to indicate all to be the present invention to want the scope of protecting, in this embodiment just with Secondary CQICH as a specific embodiment, be not limited to the resource assignation of Secondary CQICH.

Mode three:

The CQI information of all carrier waves of terminal is fed back in a carrier wave; The resource area of CQICH is divided by a certain basic granularity, the base station uses the Bitmap mode to notify the resource division of terminal CQICH, and for each CQICH sets up new index, terminal is determined the CQICH resource that its each carrier wave is shared according to the division Bitmap and the CQICH index of CQICH resource.

Figure 10 is the schematic diagram of resource organizations's mode of employing mode three, specifically comprises:

Step 1: resource area is notified terminal Secondary CQICH by using broadcasting, multicast, mode of unicast or fixed position mode in the base station;

Step 2: Secondary CQICH resource division bitmap is broadcasted according to the division of Secondary CQICH in the base station, and its resource division Bitmap is 0010001000010001, wherein the end of " 1 " expression resource division; And rebulid index for each Secondary CQICH;

Step 3: the base station is given terminal the Secondary CQICH index clean culture that each carrier wave distributed of giving each terminal.Terminal just can be determined the Secondary CQICH resource that it takies according to the division Bitmap and the Secondary CQICH index of Secondary CQICH resource area, resource.

This mode can be applied among all CQICH, the resource area of CQICH is divided by a certain basic granularity, the base station uses the Bitmap mode to notify the resource division of terminal CQICH, and for each CQICH sets up new index, terminal is determined the CQICH resource that its each carrier wave is shared according to the division Bitmap and the CQICH index of CQICH resource.The CQICH resource adopts the Bitmap mode to indicate all to be the present invention to want the scope of protecting, in this embodiment just with Secondary CQICH as a specific embodiment, be not limited to the resource assignation of Secondary CQICH.
