Description

The equipment of control channel and method in the wireless communication system

Technical field

The present invention relates to wireless communication system, particularly relate to the equipment and the method for control channel in the wireless communication system.

Background technology

At present, 3GPP standardization body has set about beginning its existing system standard is carried out long-term evolution (Long Term Evolution is hereinafter to be referred as LTE).OFDM (Orthogonal Frequency Division Multiplexing is designated hereinafter simply as OFDM) technology is with its higher availability of frequency spectrum, and lower processing complexity becomes the downlink transfer scheme that LTE adopts.

Be a kind of multi-carrier modulation communication technology on the OFDM technological essence, its basic principle is the data flow of a two-forty to be decomposed into several rate data streams transmit simultaneously on one group of mutually orthogonal subcarrier.The OFDM technology is because its multicarrier character has performance advantage aspect a lot.(1) significant advantage of OFDM technology is because data parallel transmission on a plurality of subcarriers respectively, and the corresponding growth of the length of the symbol on each subcarrier is insensitive to channel delay; Add protection on each symbol at interval by further giving, (CP CyclicPrefix), under the situation of channel delay less than circulating prefix-length, can eliminate intersymbol interference (ISI) fully promptly to introduce Cyclic Prefix.Like this, each subcarrier has all experienced flat fading channel.(2) availability of frequency spectrum height of OFDM technology, ofdm signal are actual on frequency domain an overlapping, and this overlapping on improved the availability of frequency spectrum to a great extent.(3) ability of the anti-narrow band interference of OFDM technology and frequency selective fading is stronger.Can make OFDM obtain frequency diversity and time diversity gain by chnnel coding with interweaving, thereby resist narrow band interference and frequency selective fading effectively.(4) modulation of OFDM technology can realize by baseband I FFT conversion, and IFFT/FFT has ripe quick calculation method, can realize in dsp chip and hardware configuration easily.

The frame structure of the descending ofdm system of existing LTE as shown in Figure 1.Radio Resource is structure (101-103) with the frame, and frame length is identical with WCDMA, is 10ms; Each radio frames is subdivided into a plurality of subframes (104-107) (present hypothesis is that every frame comprises 20 subframes, and subframe is long to be 0.5ms); Each subframe comprises a plurality of OFDM symbols according to the difference of configuration, and short CP subframe comprises 7 symbols (108), and long CP subframe comprises 6 symbols (109).In the LTE system, need effectively to support unicast service and multicast/broadcast business simultaneously that most probable multiplex mode is a Time Division Multiplexing.Wherein the symbol of the OFDM of unicast service only needs relatively shorter Cyclic Prefix (CP, about 4.8 μ s).For multicast/broadcast business, consider to be not inclined in the LTE system to require system synchronization, and the influence of each sub-district propagation delay, the OFDM symbol of multicast/broadcast business must dispose long CP (about 16.7 μ s).Different just because of clean culture OFDM symbol with the CP length that multicast/broadcast OFDM symbol need dispose, caused the number of the OFDM symbol that can comprise in the corresponding subframe different (short 7 symbols of CP subframe, 6 symbols of long CP subframe).

In current LTE discusses, the mode that has two kinds of basic channel resources to divide.First kind is local formula transmission channel, promptly some continuous subcarriers is divided into a channel as Resource Block, and this method helps utilizing multi-user diversity, thereby improves the throughput of system.Another kind is the distributed transmission channel, the running time-frequency resource of promptly distributing to some subscriber equipmenies be distributed to whole with certain rules or partial-band in, thereby the gain of frequency diversity is bigger.These two kinds of channel distribution modes respectively have superiority and replenish mutually, can be applied in the same subframe simultaneously, thereby in a subframe, use local formula transmission channel to obtain multi-user diversity gain, use the distributed transmission channel to obtain frequency diversity gain the other subscriber equipment to some subscriber equipmenies.

The scheduling of customer equipment data and transmission are to be base unit with the Resource Block.In current discussion, the notion of Physical Resource Block (Physicalresource block) and virtual resource blocks (Virtual resource block) has been proposed about LTE down channel resources dividing mode.Physical Resource Block comprises M continuous sub-carriers on frequency domain, comprise N OFDM symbol simultaneously in time.Virtual resource blocks is abstract to channel resource on Physical Resource Block, and virtual resource blocks is divided into distributed virtual resource block and local formula virtual resource blocks.Distributed virtual resource block is corresponding to the resource of distributed transmission channel, and local formula virtual resource blocks is corresponding to the resource of local formula transmission channel.

For the convenience of narrating, the unified in the following description base unit that uses Resource Block to represent the down channel resources scheduling of the present invention.For down direction, Resource Block is corresponding to local formula virtual resource blocks or distributed virtual resource block.

In discussing at present, the system bandwidth that LTE supported comprises 1.25MHz, 1.6MHz, 2.5MHz, 5MHz, 10MHz, 15MHz and 20MHz.Subscriber equipment needs to support the system bandwidth smaller or equal to 10MHz at least, promptly in the system bandwidth transceive data that is 1.25MHz in the 10MHz.When system bandwidth is 20MHz, just have multiple UEs having different bandwidth capability like this: the subscriber equipment that promptly has is supported the system bandwidth of 20MHz, and remaining subscriber equipment is not supported.Same problem also appears in the system bandwidth of 15MHz.When the base station when subscriber equipment sends data, the bandwidth of control signaling and data all is less than or equals the bandwidth processing ability of subscriber equipment.

Corresponding to the situation that the subscriber equipment of multiple different bandwidth disposal ability is arranged in 15MHz mentioned above and the 20MHz system bandwidth, the example of existing a kind of base station transmits control signaling method as shown in Figure 2.In Fig. 2, system bandwidth is 20MHz, and all transmission in each OFDM symbol of the control signaling of subscriber equipment.Control signaling 201 and 202 is transmitted in the subband of a 10MHz wide 207, and control signaling 203 and 204 is transmitted in the subband of another 10MHz wide 208.Different therewith is that control signaling 205 and 206 is transmitted in the system bandwidth of 20MHz.Under this mode, the subscriber equipment of base station configuration 10MHz bandwidth processing ability detects control signaling 201,202,203 and 204 (specifically, the subscriber equipment that is in 10MHz bandwidth 207 detects control signaling 201 and 202, and the subscriber equipment that is in 10MHz bandwidth 208 detects control signaling 203 and 204), and the subscriber equipment of configuration 20MHz bandwidth processing ability detects control signaling 205 and 206.The resource allocation of indication subscriber equipment in the control signaling, information such as transformat.Indicate for resource allocation, control signaling 201 and 202 has been indicated in 10MHz bandwidth 207 resource allocation information corresponding to corresponding certain subscriber equipment, control signaling 203 and 204 has been indicated in 10MHz bandwidth 208 resource allocation information corresponding to corresponding certain subscriber equipment, and control signaling 205 and 206 has been indicated in whole 20MHz bandwidth the resource allocation information corresponding to corresponding certain subscriber equipment.

The method of control signaling indexed resource assignment information as described in Figure 2 mainly contains the shortcoming of two aspects:

A) in this method, the transmission bandwidth difference of the control signaling that subscriber equipment detected of different bandwidth disposal ability.Can increase the complexity of base station when configuration control signaling like this.

B) in this method, the form of the control signaling that subscriber equipment detected of different bandwidth disposal ability is also inequality usually.This is the information that needs indexed resource to distribute owing in the control signaling, and the bit number of this informational needs is relevant with indicated bandwidth usually.So also can increase the complexity of base station when configuration control signaling.

Embodiment

The present invention proposes the equipment and the method for control channel in a kind of wireless communication system, comprise the steps:

The operation of base station:

A) deployment scenario of the bandwidth of being supported greater than certain customers' equipment corresponding to system bandwidth in the wireless communication system, the base station in the above-mentioned wireless communication system is divided into two part bandwidth with its system bandwidth;

B) each subscriber equipment is given with resource block assignments in above-mentioned base station;

C) at each subscriber equipment, the master control signaling that corresponding channel resources is distributed is transmitted in above-mentioned base station in a part bandwidth;

D) when the bandwidth of above-mentioned subscriber equipment support equals system bandwidth, in the indicated channel resource of above-mentioned control signaling, above-mentioned base station transmits is indicated channel resource allocation situation in another part bandwidth corresponding to time control signaling of above-mentioned subscriber equipment;

E) above-mentioned base station sends the control signaling that comprises master control signaling and time control signaling.

In the step a) of the present invention, the deployment scenario of the bandwidth of being supported greater than certain user's equipment corresponding to system bandwidth in the wireless communication system, base station in the above-mentioned wireless communication system is divided into two part bandwidth with its system bandwidth, and wherein each part bandwidth all is less than or equal to the bandwidth that subscriber equipment is supported.In the following description, the wide B of being of the regiment commander that sets up departments, the part bandwidth is respectively B ₁And B ₂System bandwidth with 20MHz is an example, and some supports the system bandwidth of 20MHz in the subscriber equipment of its service, and some only supports the system bandwidth of 10MHz.The base station is divided into its system bandwidth the part bandwidth of two 10MHz.As shown in Figure 2, the whole system bandwidth is divided into part bandwidth 207 and 208.

In the step b) of the present invention, (CQI) indicated according to the channel quality of subscriber equipment in the base station, the bandwidth that subscriber equipment is supported, and the information such as data traffic information of subscriber equipment are given each subscriber equipment resource block assignments.The data traffic information of subscriber equipment is meant the data volume and the corresponding quality of service requirement of each subscriber equipment for descending.System bandwidth with 20MHz is an example, and corresponding to the subscriber equipment of supporting the 10MHz bandwidth, the base station is distributes resource blocks in its residing 10MHz bandwidth.Corresponding to the subscriber equipment of supporting the 20MHz bandwidth, the base station is distributes resource blocks in whole 20MHz bandwidth.

In the step c) of the present invention, corresponding to the subscriber equipment of back-up system bandwidth not, the control signaling that the base station selects control channel to come transmission channel resources to distribute in its residing bandwidth.In the following description, the control signaling that this transmission channel resources is distributed is called the master control signaling.Corresponding to the subscriber equipment of back-up system bandwidth, two kinds of situations are arranged.First kind of situation is that the base station is that all Resource Block that subscriber equipment distributed all are in certain part bandwidth in step b).In this case, the base station selects control channel to transmit the master control signaling in its part bandwidth.Second kind of situation is that the base station is in the part bandwidth B in step b) subscriber equipment institute assigned portions Resource Block ₁In and other Resource Block is in the part bandwidth B ₂In.In this case, the part bandwidth B is selected according to certain criterion in the base station ₁Or part bandwidth B ₂In a control channel transmit the master control signaling.For instance, the base station part bandwidth that can select to transmit more Resource Block is transmitted the master control signaling.In this step, also can comprise other information in the master control signaling of base station transmits, for example transformat mixes and selects to retransmit (Hybrid AutomaticRepeat Request is designated hereinafter simply as HARQ) information etc. automatically.

In the step d) of the present invention, corresponding to the subscriber equipment of back-up system bandwidth not, the situation of the channel resource allocation that they are all is transmitted in step c), therefore the situation that does not need other signaling to come indicating channel resource to distribute.

In the step d) of the present invention, subscriber equipment corresponding to the back-up system bandwidth, the base station is in the indicated channel resource of above-mentioned master control signaling, and transmission is indicated channel resource allocation situation in another part bandwidth corresponding to another control signaling of above-mentioned subscriber equipment.In the following description, this signaling is called time control signaling.It should be noted that inferior control signaling itself may comprise one or two signaling according to the difference of design.Concrete design will provide hereinafter.With Fig. 3 is example, and the base station is in the 10MHz part bandwidth 304 for Resource Block (data 302) part of user equipment allocation, and part is in the 10MHz part bandwidth 305.The allocation situation of channel resource in 10MHz part bandwidth 304 of subscriber equipment indicated in the base station in master control signaling 301.The base station is in the indicated channel resource of master control signaling 301, and transmission time control signaling 303 is indicated the allocation situation of channel resource in 10MHz part bandwidth 305 of subscriber equipment.

In the step d) of the present invention, corresponding to the subscriber equipment of back-up system bandwidth, inferior control signaling can be transmitted separately, also can with other control informations (for example transformat, HARQ information) multiplexing back transmission.Inferior control signaling and other control information multiplexing back transmission has dual mode.A kind of mode is to adopt set form, the i.e. base station channel resource that whether has been user equipment allocation in another part bandwidth no matter all includes time control signaling of the channel resource allocation situation in another part bandwidth of indication in the control signaling after multiplexing.Another mode is to adopt two kinds of forms: promptly when the channel resource that has been user equipment allocation in another part bandwidth of base station, control signaling after multiplexing comprises time control signaling of the channel resource allocation situation in another part bandwidth of indication, and other control information; When the base station was not the user equipment allocation channel resource in another part bandwidth, the control signaling after multiplexing only comprised other control information.

In step d) of the present invention, corresponding to distributed channel transmission, a kind of mode is that channel resource allocation situation in another part bandwidth is indicated with a bit information in the base station in inferior control signaling.For example use " 0 " to indicate in another part bandwidth and be not this user equipment allocation channel resource, and use " 1 " to indicate be this user equipment allocation in another part bandwidth channel resource.Also can indicate in another part bandwidth, to be this user equipment allocation channel resource, in another part bandwidth, not be this user equipment allocation channel resource and use " 1 " to indicate with " 0 ".Because adopting the main purpose of distributed transmission mode is to maximally utilise frequency diversity, thereby a kind of saving means of signaling is that the position of channel resource in two part bandwidth is identical when subscriber equipment during in the equal allocated channel resource of two part bandwidth.

Indicate channel resource allocation situation in another part bandwidth with a bit information corresponding to above-mentioned base station in inferior control signaling, the transmission means of this bit information has two kinds.First kind of mode is to adopt the mode of code division multiplexing (Code Division Multiplexing is designated hereinafter simply as CDM).A kind of implementation that adopts the CDM mode be with this bit information with a sequence modulation, and be added to and control in the some or all of subcarrier of the indicated channel resource of signaling.Another kind of mode is to adopt the mode of time-division-frequency division multiplexing, and promptly the parton carrier wave with the indicated channel resource of control signaling transmits this bit information.

In step d) of the present invention, corresponding to local formula Channel Transmission, base station transmits time control signaling has three kinds of modes:

First kind of mode is: the channel resource allocation situation of described the direct indication of control signaling in another part bandwidth.A kind of implementation is the bit mapping of indication channel resource allocation.Suppose total N available subcarrier in the system bandwidth, a Resource Block comprises M subcarrier at frequency domain, for each part bandwidth, has

Individual Resource Block.Therefore indicating the method for channel resource allocation situation in another part bandwidth with the mode of bit mapping is one of transmission The sequence of bit $a_i,i=\mathrm{1,2},...\frac{N}{2M},$ A wherein _iOn behalf of this Resource Block ,=0 do not distribute to this subscriber equipment, and a _iOn behalf of this resource block assignments ,=1 give this subscriber equipment.Can certainly use a _iOn behalf of this resource block assignments ,=0 give this subscriber equipment, and a _iOn behalf of this Resource Block ,=1 do not distribute to this subscriber equipment.

The second way is the base station by indicate the channel resource that whether has been this user equipment allocation in another part bandwidth with a bit information, and when this bit information is indicated in another part bandwidth to this user equipment allocation channel resource, indicate concrete channel resource allocation situation with independent control signaling.In the following description, an above-mentioned bit information is called time control signaling A, and the control signaling of the channel resource allocation situation that independent indication is concrete is called time control signaling B.For inferior control signaling A, a kind of mode is to indicate with " 0 " not to be this user equipment allocation channel resource in another part bandwidth, is this user equipment allocation channel resource and use " 1 " to indicate in another part bandwidth.Also can indicate in another part bandwidth, to be this user equipment allocation channel resource, in another part bandwidth, not be this user equipment allocation channel resource and use " 1 " to indicate with " 0 ".The transmission means of above-mentioned time control signaling A has two kinds.First kind of mode is to adopt the mode of CDM.A kind of implementation that adopts the CDM mode is with a sequence modulation, and in the some or all of subcarrier of the indicated channel resource of master control signaling that is added to inferior control signaling A.Another kind of mode is to adopt the mode of time-division-frequency division multiplexing, and promptly the parton carrier wave with the indicated channel resource of master control signaling transmits time control signaling A.Indicate concrete channel resource allocation situation and first kind of mode mentioned above similar with inferior control signaling B, difference is under the manner, when indicating concrete channel resource, can indicate does not have to be the situation of this user equipment allocation channel resource in another part bandwidth.With Fig. 4 is example, and the situation shown in Fig. 4 a is when be the situation of user equipment allocation channel resource in 10MHz bandwidth 406.The base station is in the 10MHz bandwidth 405 for Resource Block (data 402) part of user equipment allocation, and part is in the 10MHz bandwidth 406.The allocation situation of channel resource in 10MHz bandwidth 405 of subscriber equipment indicated in the base station in master control signaling 401.The base station is in the indicated channel resource of master control signaling 401, transmission time control signaling A (bit information) 403 indicate in 10MHz bandwidth 406 base station for this user equipment allocation Resource Block, and in inferior control signaling B404 the concrete channel resource allocation situation of indication.Situation shown in Fig. 4 b is when be not the situation of user equipment allocation channel resource in 10MHz bandwidth 406.The base station all is in the 10MHz bandwidth 405 for the Resource Block (data 408) of user equipment allocation, and the allocation situation of channel resource in 10MHz bandwidth 405 of subscriber equipment indicated in the base station in master control signaling 407.The base station is in the indicated channel resource of master control signaling 401, and transmission time control signaling A (bit information) 404 indicates that the base station is not this user equipment allocation Resource Block in 10MHz bandwidth 406.

The third mode is applicable to when the descending local formula channel of base station assigns is subjected to the restriction of continuity distribution.This restriction is meant that the base station only saves descending signaling consumption for a specific subscriber equipment continuous resource block assignments.Definition border Resource Block is two Resource Block that the part bandwidth is adjacent.As shown in Figure 5, border Resource Block 504 is a Resource Block adjacent with another 10MHz part bandwidth 507 in the 10MHz part bandwidth 506.Similarly, border Resource Block 505 is a Resource Block adjacent with another 10MHz part bandwidth 506 in the 10MHz part bandwidth 507.Under this restrictive condition, when the channel resource of the indication of master control signaling in step c) comprised the border Resource Block, usefulness time control signaling in base station was indicated the channel resource allocation situation in another part bandwidth.When the channel resource of the indication of master control signaling in step c) does not comprise the border Resource Block, because the base station be not the user equipment allocation data in another part bandwidth, so the base station need not time be controlled signaling and indicates channel resource allocation situation in another part bandwidth.With Fig. 5 is example, and the situation shown in Fig. 5 a is when the situation of having distributed the border Resource Block in 10MHz part bandwidth 507.The base station is in the 10MHz bandwidth 506 for Resource Block (data 502) part of user equipment allocation, and part is in the 10MHz bandwidth 507.The allocation situation of channel resource in 10MHz part bandwidth 506 of subscriber equipment indicated in the base station in master control signaling 501.Owing to distributed border Resource Block 504 in part bandwidth 506, concrete channel resource allocation situation is indicated in the base station in inferior control signaling 503.Situation shown in Fig. 5 b is when the situation that does not have the allocation boundary Resource Block in 10MHz part bandwidth 506.The base station all is in the 10MHz part bandwidth 506 for the Resource Block (data 509) of user equipment allocation and does not have allocation boundary Resource Block 504, so the base station does not need to indicate channel resource allocation situation in another part bandwidth with time control signaling.

In the step e) of the present invention, the base station is carried out chnnel coding and transmission respectively with master control signaling and time control signaling.

The operation of subscriber equipment:

A) subscriber equipment receives the master control signaling;

When the bandwidth of above-mentioned subscriber equipment support equals system bandwidth, subscriber equipment reads time control signaling of base station transmits according to the position of the indicated channel resource of master control signaling, and obtains channel resource allocation situation in another part bandwidth by inferior control signaling;

Above-mentioned subscriber equipment is receiving subscriber data on the Resource Block of base station assigns.

In the step a) of the present invention, subscriber equipment at first receives the master control signaling on corresponding resource.Corresponding to the subscriber equipment of back-up system bandwidth not, the base station disposes the control channel of several transmission master control signalings in its residing bandwidth; Corresponding to the subscriber equipment of back-up system bandwidth, the base station disposes the control channel (all disposing one or more control channel in each part bandwidth usually) of several transmission master control signalings in the bandwidth of whole system.When subscriber equipment and base station connected, the base station was by the residing running time-frequency resource of high-level signaling notifying user equipment control channel.Whether subscriber equipment is that it has sent the master control signaling by detecting network for the control channel of its configuration detects network.

In the step b) of the present invention, when inferior control signaling and the transmission of the multiplexing back of other control information, adopt the mode of set form corresponding with the base station, because include time control signaling of the channel resource allocation situation in another part bandwidth of indication in the control signaling after multiplexing all the time, subscriber equipment reads time control signaling according to set form.Adopt the mode of two kinds of forms corresponding with the base station, subscriber equipment detects control channel behind time control signaling and other information multiplexings respectively according to two kinds of forms.If when passing through according to a kind of form decoding back cyclic redundancy check (CRC) (Cyclic Redundance Check is designated hereinafter simply as CRC) wherein, then subscriber equipment reads according to this form and time controls signaling.If promptly when subscriber equipment according to the form decoding back that has transmission time control signaling by CRC check, then subscriber equipment is informed in that the base station is not its distributes resource blocks in another part bandwidth; And if pass through CRC check according to the form decoding back that transmission time control signaling is arranged when subscriber equipment, then subscriber equipment is informed in that the base station can obtain concrete resource block assignments information by inferior control signaling for it has distributed Resource Block and subscriber equipment in another part bandwidth.

In the step b) of the present invention, transmit corresponding to distributed channel, when channel resource allocation situation in another part bandwidth was indicated in the base station with a bit information in inferior control signaling, subscriber equipment read this bit information and obtains channel resource allocation situation in another part bandwidth.For example use " 0 " to indicate and in another part bandwidth, be not this user equipment allocation channel resource, in another part bandwidth, be this user equipment allocation channel resource and use " 1 " to indicate.The result who deciphers this bit information when subscriber equipment is during for " 0 ", and subscriber equipment is informed in that the base station is not its distributes resource blocks in another part bandwidth; And the result who deciphers this bit information when subscriber equipment is during for " 1 ", and subscriber equipment is informed in another part bandwidth the base station and has distributed Resource Block for it, and concrete resource block assignments mode with work as the forward part bandwidth in identical.

In the step b) of the present invention, first kind of mode corresponding to time control signaling of base station transmits under the local formula Channel Transmission mode, when indicate another part bandwidth with bit mapping mode in during the situation of channel resource allocation, suppose total N available subcarrier in the system bandwidth, a Resource Block comprises M subcarrier at frequency domain, has transmitted one in the inferior control signaling

The sequence of bit $a_i,i=\mathrm{1,2},...\frac{N}{2M},$ A wherein _iOn behalf of this Resource Block ,=0 do not distribute to this subscriber equipment, and a _iOn behalf of this resource block assignments ,=1 give this subscriber equipment.Subscriber equipment passes through a after reading time control signaling _iValue can obtain the situation of channel resource allocation concrete in another part bandwidth.

In the step b) of the present invention, the second way corresponding to time control signaling of base station transmits under the local formula Channel Transmission mode, subscriber equipment reads inferior control signaling A (supposing to indicate in another part bandwidth with " 0 " among time control signaling A is not this user equipment allocation channel resource, is this user equipment allocation channel resource and use " 1 " to indicate in another part bandwidth) earlier.When the result of subscriber equipment decoding time control signaling A be " 0 ", subscriber equipment was informed in that the base station is not its distributes resource blocks in another part bandwidth; And when the result of subscriber equipment decoding time control signaling A be " 1 ", subscriber equipment was informed in another part bandwidth the base station and has distributed Resource Block for it, and subscriber equipment need then read the inferior information that signaling B obtains concrete channel resource allocation of controlling.

In the step b) of the present invention, the third mode corresponding to time control signaling of base station transmits under the local formula Channel Transmission mode, promptly when continuous resource block assignments was only given a specific subscriber equipment in the base station, subscriber equipment judged whether the channel resource that the master control signaling is indicated comprises the border Resource Block.If do not comprise the border Resource Block, then the base station is not the user equipment allocation data in another part bandwidth.If comprise the border Resource Block, then subscriber equipment reads time the control signaling and obtains channel resource allocation situation in another part bandwidth.

In the step c) of the present invention, subscriber equipment has obtained the positional information of base station for the Resource Block of its distribution according to the information in master control signaling and time control signaling, thereby receives data on corresponding resource blocks.

In the equipment drawing of base station scheduling resource and emission control signaling, the control signaling maker module 602 of base station is embodiment of the present invention as shown in Figure 6.The Scheduler module 601 of base station is indicated (CQI) according to the channel quality of subscriber equipment, the bandwidth that subscriber equipment is supported, and the information such as data traffic information of subscriber equipment determine how to give each subscriber equipment with resource block assignments; The control signaling maker module 602 of base station produces the master control signaling according to the situation of resource block assignments and indicates channel resource allocation situation in the part bandwidth of its transmission, and for the subscriber equipment of back-up system bandwidth, generation time control signaling is indicated the channel resource allocation situation in another part bandwidth; Last base station will be controlled signaling and launch in emitter 603.Concrete base station hardware block diagram provides in an embodiment.

The equipment drawing of subscriber equipment processing controls signaling as shown in Figure 7, the control signal processor module 703 of subscriber equipment is embodiment of the present invention.701 receiving systems receive the radiofrequency signal that the base station sends, and carry out processing back demultiplexings in module 702 physical channel demodulation multiplexers such as radio frequency reception and analog-to-digital conversion and go out to control signaling and other physical channels.In module 703 control signal processors, when the bandwidth of subscriber equipment support equals system bandwidth, subscriber equipment reads time control signaling of base station transmits according to the position of the indicated channel resource of master control signaling, and obtains channel resource allocation situation in another part bandwidth by inferior control signaling; Subscriber equipment receiving subscriber data on the Resource Block of base station assigns then.When subscriber equipment received data, module 703 control signal processors offered module 702 physical channel demodulation multiplexers with the information of the Resource Block of base station assigns.Concrete subscriber equipment receives hardware block diagram and provides in an embodiment.
