Referring now to Fig. 1, show wireless communication system 100 according to each embodiment given here.System 100 comprises base station 102, and it can comprise a plurality of antenna sets.For example, an antenna sets can comprise antenna 104 and 106, and another group can comprise antenna 108 and 110, and other one group can comprise antenna 112 and 114.For each antenna sets shows two antennas; Yet, can utilize more or less antenna for every group.It should be recognized by those skilled in the art that base station 102 can also comprise transmitter chain and receiver chain, it comprises a plurality of parts (for example, processor, modulator, multiplexer, demodulator, demodulation multiplexer, antenna etc.) relevant with reception with the signal transmission respectively.
Every group of antenna and/or the zone of specifying every group of antenna to communicate can be called the sector of base station 102.For example, the antenna sets mobile device that can be used for the sector in the zone that covers with base station 102 communicates.In the communicating by letter on forward link 118 and 124, forward link 118 that the transmitting antenna of base station 102 can utilize beam shaping to improve to be used for mobile device 116 and 122 and 124 signal to noise ratio.In addition, when base station 102 utilizes the mobile device 116 and 122 of beam shaping in being randomly dispersed in relevant overlay area to send, compare the base station and send to its all mobile devices by individual antenna, the mobile device in the neighbor cell can be subjected to littler interference.In addition, as shown in the figure, mobile device 116 and 122 can use equity or ad hoc technology to come direct communication each other.
According to an example, system 100 can be multiple-input and multiple-output (MIMO) communication system.In addition, system 100 can utilize basically the duplex technology of any type come divide communication channels (for example, forward link, reverse link ...), described duplex technology is FDD, TDD etc. for example.Can provide these channels be used for mobile device 116 and 122 and the base station between send control data (perhaps for example, in peering structure, sending to mobile device 122) from mobile device 116.In an example, base station 102 can send to mobile device 116 and 122 to be confirmed or non-affirmation (ACK), and mobile device 116 and 122 can be to base station 102 transmitting channel quality information (CQI). Mobile device 116 and 122 can use ACK to determine whether base station 102 receives and communicate by letter, and base station 102 can use the CQI data to come to mobile device 116 and 122 allocation of channel resources may.
In an example, the channel that is used for sending control data can be had to place communication tactfully, for example in assigned frequency and/or fixed time section, the equipment that makes can confirm that control channel is with receiving control information.For example, aspect this, control channel can be determined in advance and be configured in statically or dynamically mobile device 116 and 122 and/or base station 102 in.In addition, the structure of the control data on the control channel also can pre-determine and dispose.In some wireless multiple-access communication systems, third generation partner program (3GPP) Long Term Evolution (LTE) for example can require or the control channel of expecting to be used to specify mobile device 116/122 and/or base station 102 moved or frequency hopping in one or more time periods.Yet, for example mobile device 116/122 compare base station 102 and/or bottom-layer network with the situation that still less frequency or bandwidth capacity are operated under, under the situation that is not having certain protection time slot, possibly can't realize specific frequency hopping.
For example, in 20MHz 3GPP LTE cordless communication network, can require mobile device 116 and/or 122 on the logic channel of an end that is being positioned at frequency during the time period, to send control data, then frequency hopping to the channel that is positioned at the frequency other end to realize frequency diversity; For 10MHz equipment, for example, can not realize this frequency hopping usually under greater than the situation of 10MHz in the frequency hopping span.Therefore, in the network of the network bandwidth, can use the frequency hopping of replacement to realize different frequency diversities with control channel to this equipment component greater than the bandwidth of a part of mobile device.In a example at 3GPP LTE scene, 10MHz equipment can be in the control channel on the end of frequency frequency hopping, and needn't frequency hopping to the other end of whole frequency.Yet, support the mobile device of 20MHz communication can continue an end frequency hopping from frequency to the other end.In this respect, do not need the minimum transfer frequency of mobile device 116 and/or 122 is made amendment, and keep frequency diversity for control channel.
Show a kind of communicator 200 that is used for wireless communications environment with reference to Fig. 2.This communicator 200 can be base station or its part, mobile device or its part or the random communication means basically that is received in the data that send in the wireless communications environment.This communicator 200 can comprise: control data definition device 202, and it constitutes control data (for example, ack msg and/or CQI data); Symbol mapper 204, it is with data or the sign map a plurality of parts (for example, the tone of an OFDM symbol) to frequency; And transmitter 206, it sends mapped data.
According to an example, this communicator 200 can be sent to the control data about communication channel for example one or more distinct devices.For example, in order to help this communication, control data can be measured and constitute to control data definition device 202, for example ack msg and/or CQI data.Can utilize symbol mapper 204 that control data is suitably placed is used in the transfer bandwidth; In an example, this suitable bandwidth location can require given control data frequency hopping around this bandwidth.In an object lesson, 3GPP LTE can place control data the edge of available bandwidth, and requires to carry out frequency hopping for each given interval.Under the situation of frequency hopping in the transmission rate scope that can use communicator 200, the mapping control data that symbol mapper 204 can be suitable is so that carry out frequency hopping between the higher scope of bandwidth and lower scope edge.
Yet, be lower than under the situation that is used for the required transmission rate of frequency hopping in the transmission rate of communicator 200, can carry out less frequency hopping.This less frequency hopping can be that frequency hopping arrives the frequency different with original frequency, but still in being exclusively used in the initial edge scope of control data.For example, in 20MHz 3GPPLTE network, wherein this network has 3MHz in each edge and can be used for control data (keep 14MHz be used for other data), is 14MHz basically for the minimum frequency hopping of the control data of the communicator of supporting 20MHz.Therefore, for the communicator of supporting 10MHz, frequency hopping can occur in the 3MHz part of the bandwidth that is initially the control channel distribution.Therefore, maximum frequency hopping is 3MHz basically, and it can be realized by the communicator of supporting 10MHz.Support the communicator of 20MHz can continue from an edge frequency hopping to another edge.In addition, be substantially equal at system or the network bandwidth under the situation of bandwidth of all communicators basically wherein, these communicators also can be from an edge frequency hopping of bandwidth to another edge.Symbol mapper 204 can be assigned to symbol with control data according to selected hopping structure.
In another example, have under the situation of a part of communicator support bandwidth lower than network at network (for example, 3GPP LTE network), control channel can be the dissymmetrical structure in available bandwidth edge.Should be noted that can be according to specifying this dissymmetrical structure pro rata at the number that the number of the communicator of network bandwidth place communication is compared the communicator that can not communicate by letter.Therefore, use above-mentioned example, can use the 2MHZ of most approaching edge to be used for control data in an edge of 20MHz bandwidth, and, suppose that 6MHz is used for control data altogether, then can use the 4MHz of most approaching edge in another edge.In an example, the communicator of supporting low bandwidth more (for example, support the communicator of 10MHz) can utilize the 4MHz part so that frequency hopping in inherent this part of section at the appointed time, and support the communicator of complete network frequency hopping can be in the 2MHz edge frequency hopping.Can utilize symbol mapper 204 that this frequency hopping function is provided.In this mode, realized being used for the frequency diversity of control data for communicator with a plurality of throughput capacities.Transmitter 206 can send by symbol mapper 204 mapped symbol.Should be noted that before sending and/or shining upon, can be to these encoding symbols, modulation etc.
Referring now to Fig. 3, show a kind of wireless communication system 300, it can communications of control data, promotes frequency diversity by frequency hopping simultaneously.System 300 comprises base station 302, and it communicates with mobile device 304 (and/or different mobile device (not shown) of arbitrary number).Base station 302 can be to mobile device 304 transmission information on forward link channel; In addition, base station 302 can be from mobile device 304 reception information on reverse chain channel.In addition, system 300 can be a mimo system.In addition, system 300 can be operated in OFDMA wireless network, the 3GPP LTE wireless network etc.In addition, in an example, below shown in the base station 302 and parts and the function described also can appear in the mobile device 304, and vice versa; For being easy to explanation, shown in do not comprise these parts in the structure.
In an example, mobile device 304 can be set up the communication channel with base station 302, and can receive the control data communication information, for example is used to the frequency and/or the frequency hopping information of communicating by letter.For example should be noted that this control data communication information can be from the base station 302 sends to mobile device 304, sends from different equipment, precoding in mobile device 304 perhaps is configured in mobile device 304.This control data communication information can comprise the standard of the control data that is used to transmit following equipment and mobile device 304, wherein said equipment has the basic identical or bigger bandwidth capacity of current bandwidth that utilizes with base station 302, and described mobile device 304 has lower bandwidth capacity.For example, this is favourable in foregoing 3GPP LTE network configuration.In this respect, should be noted that in an example,, then can constitute these instructions based on the bandwidth capacity that obtains mobile device 304 if send by base station 302.
Control data definition device 312 can obtain control data, for example ACK or CQI data, sending to base station 302, and encoder 314 can paired domination number according to encoding.Subsequently, symbol mapper 316 can place control data the appropriate location of the frequency of the control data communication information definition that receives as passing through.As mentioned above, in 3GPP LTE network or similar structures, this can comprise that the bandwidth capacity based on mobile device 304 comes data are carried out frequency hopping to be used for frequency diversity.If mobile device 304 since bandwidth constraint and can not be on entire available bandwidth frequency hopping, then the control data communication information can indicate in the control frequency on a special-purpose edge of bandwidth paired domination number according to carrying out frequency hopping.If mobile device 304 can utilize the whole bandwidth of communication channel, then the control data communication information can indicative of frequency hopping will occur in a edge from bandwidth to another edge.Symbol mapper 316 can be suitable the realization hopping scheme, thereby keep frequency diversity for the mobile device 304 of a plurality of capacity.Subsequently, mobile device 304 can be on control channel sends to control data base station 302.
When the data that receive from mobile device 304, control data can be confirmed by utilizing the control channel structure in control channel dispenser 306 definite bandwidth in base station 302.As mentioned above, control channel can be synchronously or is realized (for example, based on the equipment of network enabled bandwidth and the ratio of the equipment of network enabled bandwidth not) asynchronously.Control channel analyzer 308 can be determined the correlation bandwidth part about control data.For example, this can be based on the standard that sends to mobile device 304.Subsequently, decoder 310 can the paired domination number certificate be decoded so that be further used for base station 302.For example, be under the CQI data conditions at control data, if desired, then can use these data to come to the traffic channel assignment extra resource.In addition, should be noted that control channel is not limited to the edge in frequency, but as long as equipment carries out local frequency hopping in the bandwidth of supporting, the control channel frequency that is kept just can be arranged in any basically position of available bandwidth.
Referring now to Fig. 4, show the example Synchronization Control structure 400 of the frequency-hopping mode of the equipment that in cordless communication network, is used to have the different bandwidth capacity.This control structure 400 utilizes the edge of bandwidth to send control data.At 402 places and the control channel of representing to be used for each equipment at four grids at 404 places; Equipment in Transmission Time Interval (being 1.0ms in this example) frequency hopping once, total bandwidth is 20MHz, and in this example, the control channel that utilizes at 402 and 404 places can have essentially identical amount of bandwidth.Should be noted that and to use random time section or frequency (total frequency and/or control frequency) basically, and these time periods need not to be equal.In addition, as shown in the figure, hopping structure can occur in two above time periods go up (for example, in Transmission Time Interval once more than frequency hopping); Employed in the drawings numeral and tolerance are selected for ease of explanation.
In this example, the equipment that is labeled as C, L, F and I can send with the frequency of abundance so that carry out frequency hopping to be used for control frequency diversity purpose on bandwidth.The equipment that is labeled as A, B, D, E, G, H, J and K can not be done under the situation of certain guard time like this not having; Yet these equipment send on single control frequency edge.Aspect this, to second time period, be in the equipment I of top control frequency and L frequency hopping to edge, bottom control frequency from very first time section; Yet equipment G and H frequency hopping be to more than the frequency, and equipment J and K frequency hopping be below frequency, but not always frequency hopping to the edge, bottom.Equally, equipment C and F from a time period to the next time period from the bottom margin frequency hopping to top, and device A and B frequency hopping be to more than the frequency, but always frequency hopping is not to top, and D and E frequency hopping are below frequency.Therefore, realize that under the situation of the bandwidth capacity that does not change mobile device frequency hopping to be used for the control channel frequency diversity, remains in the available bandwidth of equipment for the continuous time period simultaneously.Should be noted that control channel is not limited to the edge in frequency, but as long as equipment carries out local frequency hopping in the bandwidth of supporting, the control channel frequency that is kept just can be arranged in any basically position of available bandwidth.As shown in the figure, for the equipment of supporting 10MHz, the bandwidth of being utilized that is used for control channel is less than 10MHz, promptly as shown in the figure less than half of 20MHz bandwidth.Therefore, control channel need be at the bottommost edge, as long as but in this example, be used for gross space that equipment carries out frequency hopping less than 10MHz, control channel just can move up.
Referring now to Fig. 5, show the asynchronous control structure 500 of example of the frequency-hopping mode of the equipment that in cordless communication network, is used to have the different bandwidth capacity.This control structure 500 utilizes the edge of bandwidth to send control data.At 502 places and the control channel of representing to be used for each equipment at four grids at 504 places; Equipment in Transmission Time Interval (being 1.0ms in this example) frequency hopping once, total bandwidth is 20MHz, and in this example, can utilize different amount of bandwidth 502 with the control channel at 504 places.In addition, have the equipment of different bandwidth capacity basically and can have control channel in the different edges of bandwidth.Should be noted that and to use random time section or frequency (total frequency and/or control frequency) basically, and these time periods need not to be equal.In addition, as shown in the figure, hopping structure can occur in two above time periods go up (for example, in Transmission Time Interval once more than frequency hopping); Employed in the drawings numeral and tolerance are selected for ease of explanation.
In this example, the equipment that is labeled as C, L, F and I can send with the frequency different with the equipment that is labeled as A, B, D, E, G, H, J and K.The equipment that is grouped in the identical category can carry out frequency hopping to control frequency in the single edge of bandwidth.Therefore, C, L, F and I from the very first time at interval to whole frequency hopping in top of second time interval, and A, B, D, E, G, H, J and K frequency hopping in bottom margin.Therefore, keep frequency diversity, and equipment needn't carry out frequency hopping outside capacity for control channel.Should be noted that in this example equipment C, L, F and I compare network can have littler bandwidth capacity, because needed frequency hopping is basically less than system bandwidth.
In this example, because need only being used for the space of four equipment, the top frequency edges sends control data, can be so be exclusively used in the size of the frequency field of control data less than the bottom frequency, it need be used for the space of eight equipment.As mentioned above, can divide the control frequency edge based on the needed size of place capacity at least in part.For example, 3.6MKz is used for whole control channels and distributes if desired, then can be pro rata with the channel distribution of edge to the equipment that utilizes this channel.Because the equipment of the similar capacity of twice is arranged in top, think that this edge distributes the bandwidth (or 2.4MKz) of twice, and remaining (1.2MKz) distributed to top.Should be noted that these numerals are only used for for example; In the frequency that can utilize arbitrary number basically or size aspect this, distribution etc.
With reference to Fig. 6-7, show and provide the control channel frequency hopping relevant method for the equipment that in cordless communication network, has the different bandwidth capacity.Although these methods are illustrated and are described as a series of actions for ease of explanation, but be to be understood that and recognize, these methods are not subject to the order of action, can occur in sequence and/or take place simultaneously with other action that illustrates here and describe according to different according to some actions of one or more embodiment.For example, it will be appreciated by those skilled in the art that and recognize that a kind of method can alternatively be expressed as for example a series of relevant state or the incident in state diagram.In addition, according to one or more embodiment, can not need the action shown in all to realize a kind of method.
