Turning now to Figure 12 D, the figure schematic diagram 1240 of the example, non-limiting embodiment of graphical spectrum is shown.Specifically Ground shows frequency spectrum 1242 for the distributing antenna system of transmission modulated signal, and the modulated signal is at it from one Or multiple original/eigenfrequency spectrum segments occupy downlink at frequency spectrum 1242 by frequency conversion (for example, via up-conversion or down coversion) later The frequency channels of link segment 1206 or uplink spectrum segment 1210.

In the example presented, downlink (downlink) channel band 1244 includes by individual downlink tone spectral slice Multiple downlink frequency channels that section 1206 indicates.Equally, uplink (uplink) channel band 1246 includes by individual uplink Multiple uplink frequency channels that link spectral segment 1210 indicates.The spectral shape of independent spectral slice means for each modulation The placeholder of the frequency of signal and associated reference signal, control channel and clock signal distribution.Downlink tone spectral slice Section 1206 or the response of the actual spectrum of each frequency channels in uplink spectrum segment 1210 will be based on used agreement With modulate and further changed according to the time.

According to asymmetric communication system, the quantity of uplink spectrum segment 1210 can be less than or greater than downlink tone The quantity of spectral slice section 1206.In this case, up channel frequency band 1246 can be narrower than or be wider than down channel frequency band 1244. In alternative solution, in the case where implementing symmetrical communication systems, under the quantity of uplink spectrum segment 1210 can be equal to The quantity of line link spectral slice 1206.In this case, the width of up channel frequency band 1246 can be equal to down channel The width of frequency band 1244, and bit padding or other data filling techniques can be used to compensate the variation of upstream traffic.To the greatest extent Pipe down channel frequency band 1244 is shown at the frequency lower than up channel frequency band 1246, but in other embodiments, Down channel frequency band 1144 can be located at the frequency higher than up channel frequency band 1246.In addition, the quantity of spectral slice and these Respective frequencies position of the spectral slice in frequency spectrum 1242 can over time and dynamic changes.For example, can be in frequency spectrum Common control channel is provided in 1242 (not shown), the common control channel can indicate each downlink to communication node 1104 The frequency location of link spectral segment 1206 and each uplink spectrum segment 1210.Depending on traffic conditions or need The network demand of bandwidth is redistributed, downlink spectrum segment 1206 can be changed by means of the common control channel With the quantity of uplink spectrum segment 1210.In addition, downlink spectrum segment 1206 and uplink spectrum segment 1210 It need not separate and be grouped.For example, common control channel can be in an alternating fashion or symmetrical any can be or can not be Other combinations are to identify the downlink spectrum segment 1206 for being followed by uplink spectrum segment 1210.It should be further noted that It is that, instead of utilizing common control channel, multiple control channels can be used, each control channel identifies one or more frequency spectrum pieces The frequency location of section and the type (that is, uplink or downlink) of spectral slice.

In addition, although down channel frequency band 1244 and up channel frequency band 1246 are all shown as occupying single continuous frequency Band, but in other embodiments depends on available frequency spectrum and/or used communication standard, can using two or more Multiple up channel frequency bands and/or two or more down channel frequency bands.Uplink spectrum segment 1210 and downlink The frequency channels of spectral slice 1206 can be by according to DOCSIS 2.0 or more advanced standard agreement, WiMAX standard agreement, super 4G the or 5G voice-and-data agreements such as wideband protocol, 802.11 standard agreements, LTE protocol and/or other standards communication protocols View modulates, occupying through frequency variation signal of formatting.It, can be in these agreements other than the agreement for following Current standards Any agreement is modified for that shown system is combined to be operated together.For example, can to 802.11 agreements or other Agreement is modified to include additional guide and/or individual data channel, thus provide over a wider area collision detection/ Multiple access access (for example, allowing to hear each other via the equipment that certain frequency channel is communicated).In various embodiments, uplink All uplink frequency channels of link spectral segment 1210 and all downlinks of downlink spectrum segment 1206 Frequency channels are formatted all according to same communication protocol.However, in alternative solution, it can be in one or more uplinks The downlink chain of the uplink frequency channel of link spectral segment 1210 and one or more downlink spectrum segments 1206 In the frequency channels the two of road using two or more different agreements come it is for example compatible with various client devices and/ Or it is operated in different bands.

It should be noted that modulated signal can be collected from different original/eigenfrequency spectrum segments, to gather frequency In spectrum 1242.By this method, the first part of the uplink frequency channel of uplink spectrum segment 1210 can be with uplink The uplink frequency channel of link spectral segment 1210 by from one or a different original/eigenfrequency spectrum segment into The second part of row frequency conversion is adjacent.Similarly, the first part of the downlink frequency channel of downlink spectrum segment 1206 It can be from the downlink frequency channel of downlink spectrum segment 1206 by from one or a different original/intrinsic The second part that spectral slice carries out frequency conversion is adjacent.For example, can by 802.11 channel of one or more 2.4GHz of frequency conversion By adjacent with 802.11 channel of one or more 5.8GHz of frequency spectrum 1242 being also converted to centered on 80GHz.It answers When it is noted that each spectral slice, which can have pilot signal etc., can be used for generation under some frequency and phase The associated reference signal of local oscillator signals, the local oscillator signals provide the one or more to this spectral slice Frequency channels are from its drop point in frequency spectrum 1242 to the frequency conversion for being back to its original/eigenfrequency spectrum segment.

Turning now to Figure 12 E, the figure schematic diagram 1250 of the example, non-limiting embodiment of graphical spectrum is shown.Specifically Ground is presented as combined by the transceiver 1230 of communication node 1140A or the transceiver 1232 of communication node 1104B-E to selected The spectral slice selection that the signal processing that spectral slice executes is discussed.As shown, selection includes uplink channel frequency Specific uplink frequency-portions 1258 with 1246 one of uplink spectrum segment 1210 and believe including downlink The particular downlink frequency-portions 1256 of one of the downlink spectrum segment 1206 of road frequency band 1244 are filtered by channel selection Wave passes through, wherein the rest part of uplink channel band 1246 and downlink channel frequency band 1244 is filtered out --- i.e. It is attenuated, to mitigate the adverse effect of the processing to the expected frequency channel passed through by transceiver.Although should be noted that The single specific uplink spectral slice 1210 of selection and particular downlink spectral slice 1206 are shown, but in other realities It applies in example, two or more uplink spectral slices and/or downlink spectrum segment can be made to pass through.

Although transceiver 1230 and 1232 can based on static channel filter uplink frequency part 1258 and under It is operated in the case that uplink frequency part 1256 is fixed, but it is as discussed previously, it can be used and believe via control Transceiver 1230 and 1232 is dynamically configured to specific frequency selection by the instruction that road is sent to transceiver 1230 and 1232.With This mode, can by other network elements of macro base station 1102 or communication network by the uplink frequency channels of corresponding spectral slice and Downlink frequency channels are dynamically assigned to each communication node, so as to the performance of Optimum distribution formula antenna system.

Turning now to Figure 13 A, the flow chart of the example, non-limiting embodiment of method 1300 is shown.Method 1300 can be with It is used together with the one or more functions presented in conjunction with Fig. 1 to Figure 12 with feature.Method 1300 may begin at step 1302, in this step, the equal base stations of the macro base station 1102 of Figure 11 A determine the travel rate of communication equipment.The communication is set The standby mobile communication equipment that can be one of mobile device 1106 illustrated in such as Figure 11 B or static communication equipment (for example, Communication equipment in house or commercial undertaking).Base station can use radio honeycomb communication technology (for example, LTE) and communication equipment Directly communicated, the radio honeycomb communication technology enable base station by from the communication equipment receive location information come The movement of the communication equipment is monitored, and/or voice service and/or data service etc. can be provided to the communication equipment Radio communication service.During communication session, base station and communication equipment utilize the one of some bandwidth (for example, 10MHz-20MHz) A or multiple spectral slices (for example, resource block) come exchange with some intrinsic/original carrier frequency (for example, 900MHz frequency band, 1.9GHz frequency band, 2.4GHz frequency band, and/or 5.8GHz frequency band etc.) wireless signal that is operated.In some embodiments, root According to the timeslot scheduling of communication equipment being distributed to by base station come using these spectral slices.

It, can be according to the GPS coordinate provided from communication equipment by means of cellular radio signal to base station at step 1302 To determine the travel rate of communication equipment.If travel rate is more than threshold value (for example, 25 mph.) at step 1304, Then at step 1306, the radio resource that base station can use base station continues to provide wireless service to communication equipment.In another party Face, if communication equipment has the travel rate lower than the threshold value, base station can be configured for further determining described Whether communication equipment can be redirectrf to communication node so that the radio resource of base station can be used for other communication equipments.

For example, it is assumed that base station detects that communication equipment has slow travel rate (for example, 3mph or close to static).? In some cases, base station can also determine that the communication equipment is placed in particular communication node 1104 by the current location of communication equipment Communication range in.It is specific logical that base station can also determine that the slow travel rate of communication equipment will be such that the communication equipment maintains Believe that sufficiently long grace time (another threshold testing that can be used by base station) is in the communication range of node 1104 to prove It is correct that the communication equipment, which is redirectrf to particular communication node 1104,.Once having carried out such determination, base station is just It may be advanced to step 1308 and select the communication node 1104 being located in the communication range of communication equipment so as to the communication Equipment provides communication service.

Therefore, the selection course executed at step 1308 can be based on according to the GPS provided from communication equipment to base station Coordinate and the communications device locations of determination.Selection course is also based on the travel track of communication equipment, and the track can be It is determined according to several examples of the GPS coordinate provided by the communication equipment.In some embodiments, base station can determine The track of communication equipment is placed in the communication equipment for finally adjacent with the communication node selected by step 1308 latter logical In the communication range for believing node 1104.In the present embodiment, base station can inform this track to multiple communication nodes 1104, so that The switching for the communication service that opposite communication equipment provides can be coordinated by obtaining communication node 1104.

Once having selected one or more communication nodes 1104 at step 1308, base station can proceed to step 1310, in this step, base station distributed at first carrier frequency (for example, 1.9GHz) one or more spectral slices (for example, Resource block) to be used by communication equipment.By base station selected first carrier frequency and/or spectral slice need not in base station and The carrier frequency and/or spectral slice used between communication equipment is identical.For example, it is assumed that base station and communication equipment are utilizing Carrier frequency under 1.9GHz carries out wireless communication between each other.At step 1310, base station can be in step 1308 institute The communication node of choosing selects different carrier frequencies (for example, 900MHz), to be communicated with communication equipment.Similarly, base Standing can distribute and (multiple) spectral slice (for example, resource block) for using between base station and communication equipment for communication node And/or different (multiple) spectral slice and/or timeslot scheduling of timeslot scheduling of (multiple) spectral slice.

At step 1312, base station can generate (multiple) frequencies distributed in step 1310 under first carrier frequency (multiple) first modulated signal in spectral slice section.(multiple) first modulated signals may include being directed to communication equipment Data, the data indicate voice communication session, data communication session or combinations thereof.At step 1314, base station can will be located (multiple) first modulated signal up-conversion under the first intrinsic carrier frequency (for example, 1.9GHz) (is filtered using frequency mixer, band logical Wave device and other circuit systems) to the second carrier frequency (for example, 80GHz), to be selected at step 1308 being directed to Such signal is transmitted in one or more frequency channels of the downlink spectrum segment 1206 of communication node 1104.It is alternative Ground, (multiple) first that base station can provide under first carrier frequency to the first communication node 1104A (illustrating in Figure 11 A) adjust Signal processed is so as to up-conversion to the second carrier frequency, in the downlink for being directed to the communication node 1104 selected at step 1308 It is transmitted in one or more frequency channels of link spectral segment 1206.

At step 1316, base station can be with firing order communication equipment is changed into the communication that step 1308 place is selected Node 1104.When communication equipment carries out direct communication using the radio resource of base station and the base station, these instructions can be by It is directed to the communication equipment.Alternatively, these instructions can be by means of the downlink spectrum segment that illustrates in Figure 12 A 1206 control channel 1202 is communicated to the communication node 1104 selected at step 1308 place.Step 1316 can be in step Before 1312-1314, later or simultaneously occur.

Once these instructions have been launched, base station can proceed to step 1318, and in this step, the base station exists Transmitting is under the second carrier frequency (for example, 80GHz) in one or more frequency channels of downlink spectrum segment 1206 The first modulated signal, to be emitted by the first communication node 1104A (being illustrated in Figure 11 A).Alternatively, in step At 1314, the first communication node 1104A can execute up-conversion, receive from base station in the first intrinsic carrier frequency to work as Under (multiple) first modulated signal when transmit and be in one or more frequency channels of downlink spectrum segment 1206 The first modulated signal under second carrier frequency.First communication node 1104A can serve as principal communication node, for according in step It is distributed at rapid 1310 to the downlink spectrum segment 1206 that each communication node 1104 distributes to downlink communication node 1104 The down link signal generated by base station.It can be by means of the control channel that is illustrated in fig. 12 by the first communication node 1104A The instruction emitted in 1202 provides the distribution of downlink spectrum segment 1206 to communication node 1104.At step 1318, (multiple) first under the second carrier frequency are received in one or more frequency channels of downlink spectrum segment 1206 The communication node 1104 of modulated signal can be configured for: (multiple) first modulated signal by described in downconverts to first carrier Frequency, and removed using the pilot signal of the supply of (multiple) first modulated signal described in use by downlink spectrum segment (for example, phase distortion) is distorted caused by the distribution that 1206 communications hop between communication node 1104B-D jumps onto.Specifically, Export pilot tone it can believe from the local oscillator signals for generating frequency upconversion (for example, via frequency multiplication and/or frequency division) Number.When needing to carry out down coversion, pilot signal can be used to rebuild the frequency of local oscillator signals and phasing version This (for example, via frequency multiplication and/or frequency dividing), it is original in frequency band so that modulated signal is back to it with minimum phase error Part.In this way, it is possible to which the frequency channels to communication system carry out frequency conversion, to be transmitted via distributing antenna system And its initial protion in frequency spectrum is then return to emit to wireless client device.

Once downconversion process is completed, at step 1322, communication node 1104 can utilize and distribute to communication node 1104 same spectral slice emits the first modulated signal under the first intrinsic carrier frequency (for example, 1.9GHz) to logical Believe equipment.It can coordinate step 1322, so that it has been changed into according to the instruction provided at step 1316 in communication equipment Occur after communication node 1104.In order to keep this transformation seamless, and in order to avoid interrupting between base station and communication equipment Existing wireless communications session, the instruction provided in step 1316 can guide communication equipment and/or communication node 1104 to be converted to (multiple) distributed spectral slice and/or timeslot scheduling, the communication node 1104 selected as communication equipment and step 1308 place Between a part of enrollment process and/or subsequent.In some instances, such transformation may require communication equipment in short-term Between concurrently wirelessly communicated with base station and communication node 1104 in section.

Once communication equipment is successfully transitioned to communication node 1104, communication equipment can terminate the channel radio with base station Letter, and continue communication session by means of communication node 1104.The wireless service terminated between base station and communication equipment makes base The certain radio resources stood can be used for being used together with other communication equipments.Although should be noted that base station aforementioned Wireless connection is entrusted into selected communication node 1104 in step, but the communication session between base station and communication equipment by means of The network of the communication node 1104 illustrated in Figure 11 A continues as before.However, the difference is that, base station no longer needs It is communicated using the radio resource of their own with communication equipment.

In order to provide two-way communication between base station and communication equipment, by means of the network of communication node 1104, Ke Yiming Enable communication node 1104 and/or communication equipment using one or more uplinks frequency in the uplink illustrated in Figure 12 A One or more frequency channels of spectral slice section 1210.At step 1316, it can be mentioned to communication node 1104 and/or communication equipment For uplink instruction, one of the enrollment process between communication node 1104 selected as communication equipment and step 1308 place Divide and/or subsequent.Therefore, when the data that there is communication equipment it to need transmitting to base station, the communication equipment can be wireless Ground transmitting can be adjusted at step 1324 by received (multiple) second under the first intrinsic carrier frequency of communication node 1104 Signal processed.(multiple) second modulated signals may include providing at step 1316 to communication equipment and/or communication node Instruction in specify one or more uplink spectrum segments 1210 one or more frequency channels in.

In order to which (multiple) second modulated signal is sent to base station, communication node 1104 can be at step 1326 by these Signal is from the first intrinsic carrier frequency (for example, 1.9GHz) up-conversion to the second carrier frequency (for example, 80GHz).On making Row communication node and/or base station can remove distortion, and (multiple) second modulated signal under the second carrier frequency can be in step Emitted by communication node 1104 using one or more uplink pilots 1208 at 1328.Once base station is via logical Letter node 1104A receives (multiple) second modulated signal under the second carrier frequency, base station can at step 1330 incite somebody to action These signals downconvert to the first intrinsic carrier frequency from the second carrier frequency to obtain by communication equipment in step 1332 The data of offer.Alternatively, the first communication node 1104A, which can be executed, modulates (multiple) second under the second carrier frequency Signal to the first intrinsic carrier frequency down coversion, and to base station provide caused by signal.Then, base station can be to first (multiple) second modulated signal under intrinsic carrier frequency is handled, if so as to direct to be carried out with base station and communication equipment How base station should handle that the signal from communication equipment is similar in the case where wireless communication or exact same way is retrieved The data provided by communication equipment.

Abovementioned steps method 1300 provides one kind for base station 1102 and makes radio resource (for example, fan antenna, frequency spectrum) The mode for the communication equipment that can be used for fast moving, and in some embodiments, pass through the communication equipment weight that will slowly move It is directed to and is communicatively coupled to one or more communication nodes 1104 of base station 1102 to improve bandwidth availability ratio.For example, it is assumed that A communication node 1104 in ten (10) that there is it can be redirectrf to mobile and/or static communication equipment for base station 1102.Into One step assumes that this 10 communication nodes 1104 have the communication range of substantially non-overlap.

It is further assumed that base station 1102 has left during particular time-slot and has been in certain under special carrier frequency These spectral slices are distributed to this all 10 communication nodes by spectral slice (for example, resource block 5,7 and 9), the base station 1104.During operation, base station 1102 can be configured as be not utilized as communication node 1104 and reserve in the timeslot scheduling phase Between and the resource block 5,7 and 9 under the carrier frequency, to avoid interfering.When base station 1102 detect it is slowly moving or quiet When communication equipment only, can the position based on the communication equipment communication equipment is redirectrf to this 10 communications Different communication node in node 1104.For example, when the communication of particular communication devices is redirectrf to specific lead to by base station 1102 When believing node 1104, base station 1102 can will become during distributed time slot and on the resource block 5,7 and 9 under carrier frequency One or more spectral ranges on frequency to the downlink (participating in Figure 12 A) for distributing to discussed communication node 1104.

The communication node 1104 discussed can also be distributed to it can be used to believe the communication provided by communication equipment Number it is redirectrf to the one or more of one or more uplink spectrum segments 1210 in the uplink of base station 1102 Frequency channels.It can be by communication node 1104 according to dividing in one or more corresponding uplink spectrum segments 1210 It is concurrently incident upon base station 1102 to carry out up-conversion to this kind of signal of communication with uplink frequency channel, to be handled.It can Downlink and uplink frequency channel to be distributed by means of control channel as depicted in fig. 12 by base station 1102 It is conveyed to each communication node 1104.Afore-mentioned downlink and uplink assigning process can be also used for other communication nodes 1104, to provide communication service to other communication equipments for being redirectrf to these other communication nodes by base station 1102.

In this diagram, by this 10 communication nodes 1104 to during corresponding time slot is dispatched and under carrier frequency The bandwidth availability ratio of base station 1102 effectively can be improved up to 10 times by reusing for resource block 5,7 and 9.Although base station 1102 is not It is able to use again to carry out wirelessly for the resource block 5,7 and 9 that this 10 communication nodes 1104 are reserved with other communication equipments Communication, but communication equipment is redirectrf to the ability for reusing 10 different communication nodes 1104 of these resource blocks by it Effectively improve the bandwidth ability of base station 1102.Therefore, in certain embodiments, base station 1102 can be improved in method 1300 Bandwidth availability ratio and the resource of base station 1102 is made to can be used for other communication equipments.

It is to be appreciated that in some embodiments, base station 1102 can be configured to selection base station 1102 The direction of antenna system reused point far from the one or more sectors for the communication node 1104 for distributing to same frequency spectrum segment The spectral slice of dispensing communication node 1104.Therefore, base station 1102 can be configured for: in some embodiments, avoid weight With the certain spectral slices for distributing to certain communication nodes 1104；And in other embodiments, pass through selection base station 1102 Other spectral slices of other communication nodes 1104 are distributed to reuse in the particular sector of antenna system.Similar concept can answer The sector as used by communication node 1104 for antenna system 1124.It can be based on by base station 1102 and/or one or more The sector that a communication node 1104 utilizes is come between base station 1102 and one or more of communication nodes 1104 using certain Reuse scheme.

Method 1300, which is also achieved, reuses tradition system when communication equipment is redirectrf to one or more communication nodes System.For example, base station and communication equipment can be carried out wireless communication utilized signaling protocol (for example, LTE) is maintained at base station In the signal of communication exchanged between communication node 1104.Therefore, when spectral slice is distributed to communication node 1104, It is being carried out between base station and communication node 1104, to the modulated signal in these segments exchange can be base station carry out with The identical signal that the direct wireless communication of communication equipment should use.Therefore, it can use added distortion mitigation feature to come Update traditional base station to execute previously described up-conversion and downconversion process, and execute in hardware and/or software with Every other function for just handling the modulated signal under the first intrinsic carrier frequency can keep being basically unchanged.Also It should be noted that in a further embodiment, the channel conversion from original frequency band to same agreement can be utilized Another frequency band.For example, the LTE channel in 2.5GHz frequency band can be up-converted in 80GHZ frequency band, to be transmitted, and And then it is downconverted to 5.8GHz LTE channel (if spectral diversity needs).

It should further be noted that in the case where the range disclosed without departing substantially from this theme, can to method 1300 into Row adjustment.For example, when base station detect communication equipment have will lead to from the communication range of a communication node to another When the track of transformation, the base station (or the communication node discussed) can be by means of the periodicity that is provided by the communication equipment GPS coordinate monitors this kind of track, and correspondingly switching of the coordinating communication equipment to other communication nodes.It can also be by method 1300 are adjusted such that when communication equipment is near transition point of the communication range from a communication node to another, can Under guiding the communication equipment and/or other communication nodes to utilize by base station (or movable communication node) firing order Certain spectral slices and/or time slot in Downlink channels and uplink channel successfully change communication, without interrupting Existing communication session.

It should further be noted that can be with method of adjustment 1300, to coordinate in a case where by communication equipment Wireless communication between communication node 1104 switches back to base station: when base station or movable communication node 1104 detect and communicate Equipment will be transitioned into except the communication range of the communication node and in the communication range of the communication equipment in some point There is no when other communication nodes.This theme discloses other adjustment contemplated to method 1300.It should further be noted that When the carrier frequency of downlink spectral slice or uplink spectrum segment is lower than the intrinsic frequency band of modulated signal, will need Carry out the inverse process of frequency conversion.That is, the modulated signal when transmission in downlink spectrum segment or uplink spectrum segment When, by frequency of use down coversion rather than up-conversion.And downlink spectrum segment or uplink spectrum are in when extracting When modulated signal in segment, by frequency of use up-conversion rather than down coversion.Can further method of adjustment 1300, to make The processing to the numerical data in control channel is synchronized with above-mentioned clock signal.Can with method of adjustment 1300, with Just the reference signal modulated or the clock modulated by the instruction in control channel is used by the instruction in control channel to believe Number.

Further method of adjustment 1300 to avoid the movement of tracking communication equipment but multiple communications can be guided instead Node 1104 emits the modulated signal (under its intrinsic frequency) of particular communication devices, without knowing which communication node is in In the communication range of the particular communication devices.Similarly, each communication node can be ordered to connect from the particular communication devices Modulated signal is received, and transmits such signal in certain frequency channels of one or more uplink spectrum segments 1210, Without knowing which communication node will receive modulated signal from the particular communication devices.This embodiment can help Reduce the implementation complexity and cost of communication node 1104.
