Turning now to Figure 16 A, the flow chart of the example, non-limiting embodiment of method 1600 is shown.Method 1600 can be with It is used together with the one or more functions presented in conjunction with Fig. 1-15 with feature.Method 1600 may begin at step 1602, In this step, the equal base stations of the macro base station 1402 of Figure 14 A determine the travel rate of communication equipment.The communication equipment can be with Be one of mobile device 1406 illustrated in such as Figure 14 B mobile communication equipment or static communication equipment (for example, house or Communication equipment in commercial undertaking).Base station can use radio honeycomb communication technology (for example, LTE) and communication equipment directly into Row communication, the radio honeycomb communication technology enable base station by receiving location information from the communication equipment to monitor The movement of communication equipment is stated, and/or the channel radios such as voice service and/or data service can be provided to the communication equipment Telecommunications services.During communication session, base station utilizes one or more of some bandwidth (for example, 10MHz-20MHz) with communication equipment A spectral slice (for example, resource block) exchanges 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, according to by base station The timeslot scheduling for distributing to communication equipment to use 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 1602 To determine the travel rate of communication equipment.If travel rate is more than threshold value (for example, 25 mph.) at step 1604, Then at step 1606, 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 1404 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 1404 to prove It is correct that the communication equipment, which is redirectrf to particular communication node 1404,.Once having carried out such determination, base station is just It may be advanced to step 1608 and select the communication node 1404 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 1608 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 1608 latter logical In the communication range for believing node 1404.In the present embodiment, base station can inform this track to multiple communication nodes 1404, so that The switching for the communication service that opposite communication equipment provides can be coordinated by obtaining communication node 1404.

Once having selected one or more communication nodes 1404 at step 1608, base station can proceed to step 1610, 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 1610, base station can be in step 1608 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 1612, base station can generate (multiple) frequencies distributed in step 1610 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 1614, 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 1608 being directed to Such signal is transmitted in one or more frequency channels of the downlink spectrum segment 1506 of communication node 1404.It is alternative Ground, (multiple) first that base station can provide under first carrier frequency to the first communication node 1404A (illustrating in Figure 14 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 1404 selected at step 1608 It is transmitted in one or more frequency channels of link spectral segment 1506.

At step 1616, base station can be with firing order communication equipment is changed into the communication that step 1608 place is selected Node 1404.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 15 A 1506 control channel 1502 is communicated to the communication node 1404 selected at step 1608 place.Step 1616 can be in step Before 1612-1614, later or simultaneously occur.

Once these instructions have been launched, base station can proceed to step 1618, 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 1506 The first modulated signal, to be emitted by the first communication node 1404A (being illustrated in Figure 14 A).Alternatively, in step At 1614, the first communication node 1404A 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 1506 The first modulated signal under second carrier frequency.First communication node 1404A can serve as principal communication node, for according in step It is distributed at rapid 1610 to the downlink spectrum segment 1506 that each communication node 1404 distributes to downlink communication node 1404 The down link signal generated by base station.It can be by means of the control channel that is illustrated in Figure 15 A by the first communication node 1404A The instruction emitted in 1502 provides the distribution of downlink spectrum segment 1506 to communication node 1404.At step 1618, (multiple) first under the second carrier frequency are received in one or more frequency channels of downlink spectrum segment 1506 The communication node 1404 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 1506 communications hop between communication node 1404B-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 1622, communication node 1404 can utilize and distribute to communication node 1404 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 1622, so that it has been changed into according to the instruction provided at step 1616 in communication equipment Occur after communication node 1404.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 1616 can guide communication equipment and/or communication node 1404 to be converted to (multiple) distributed spectral slice and/or timeslot scheduling, the communication node 1404 selected as communication equipment and step 1608 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 1404 in section.

Once communication equipment is successfully transitioned to communication node 1404, communication equipment can terminate the channel radio with base station Letter, and continue communication session by means of communication node 1404.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 1404 in step, but the communication session between base station and communication equipment by means of The network of the communication node 1404 illustrated in Figure 14 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 1404, Ke Yiming Enable communication node 1404 and/or communication equipment using one or more uplinks frequency in the uplink illustrated in Figure 15 A One or more frequency channels of spectral slice section 1510.At step 1616, it can be mentioned to communication node 1404 and/or communication equipment For uplink instruction, one of the enrollment process between communication node 1404 selected as communication equipment and step 1608 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 1624 by received (multiple) second under the first intrinsic carrier frequency of communication node 1404 Signal processed.(multiple) second modulated signals may include providing at step 1616 to communication equipment and/or communication node Instruction in specify one or more uplink spectrum segments 1510 one or more frequency channels in.

In order to which (multiple) second modulated signal is sent to base station, communication node 1404 can be at step 1626 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 1404 using one or more uplink pilots 1508 at 1628.Once base station is via logical Letter node 1404A receives (multiple) second modulated signal under the second carrier frequency, base station can at step 1630 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 1632 The data of offer.Alternatively, the first communication node 1404A, 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 1600 provides one kind for base station 1402 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 1404 of base station 1402 to improve bandwidth availability ratio.For example, it is assumed that A communication node 1404 in ten (10) that there is it can be redirectrf to mobile and/or static communication equipment for base station 1402.Into One step assumes that this 10 communication nodes 1404 have the communication range of substantially non-overlap.

It is further assumed that base station 1402 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 1404.During operation, base station 1402 can be configured as be not utilized as communication node 1404 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 1402 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 1404.For example, when the communication of particular communication devices is redirectrf to specific lead to by base station 1402 When believing node 1404, base station 1402 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 15 A) for distributing to discussed communication node 1404.

The communication node 1404 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 1510 in the uplink of base station 1402 Frequency channels.It can be by communication node 1404 according to dividing in one or more corresponding uplink spectrum segments 1510 It is concurrently incident upon base station 1402 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 figure 15 a by base station 1402 It is conveyed to each communication node 1404.Afore-mentioned downlink and uplink assigning process can be also used for other communication nodes 1404, to provide communication service to other communication equipments for being redirectrf to these other communication nodes by base station 1402.
