Technical solution of the present invention will be described in detail below by specific embodiment.
The flow chart of the communication means that Figure 1A provides for first embodiment of the invention.As shown in Figure 1A, the method for the present embodiment comprises:
Step 101, Macro are that a UE carries out ascending resource configuration, send upward signal or channel to make a UE according to described ascending resource configuration respectively to macro station and a PLN.
In the present embodiment, be described for the LPN (i.e. a LPN) of the UE of in network (i.e. a UE) and the potential access of this UE (potential access can be accessed maybe may access), other UE select the process of point of network attachment identical therewith.In various embodiments of the present invention, described network refers to and controls by Macro and Macro the network that lower each LPN forms, and each LPN passes through optical fiber or other wired or wireless modes are connected with Macro, each LPN of Macro centralized control.The coverage of each LPN and Macro has at least part to repeat.Wherein, a UE is also under the covering of Macro.
Macro is that a UE carries out ascending resource configuration, and Macro sends which or which upward signal or up channel and corresponding running time-frequency resource position thereof by ascending resource configuration instruction the one UE.In the present embodiment, Macro configures instruction the one UE to Macro or/and a LPN sends upward signal or up channel by ascending resource.Wherein, Macro can indicate a UE to send wherein any one or the combination in any such as PUSCH, PUCCH, PRACH, DMRS and SRS, but is not limited thereto.
One UE receives Macro or/and after the ascending resource configuration that sends of a LPN, according to the instruction of ascending resource configuration to Macro or/and a LPN sends upward signal or up channel.
The upward signal that step 102, Macro send a UE or channel are measured, and obtain the first out-hole run information of Macro itself, and the upward signal that a LPN sends a UE or channel are measured, and obtain the first out-hole run information of a LPN.
Wherein, the first out-hole run information refers to the out-hole run information obtained upward signal or the channel measurement of a UE transmission.The first out-hole run information of Macro refers to the out-hole run information that the upward signal that sent a UE by Macro or channel measurement obtain; The first out-hole run information of the one LPN refers to the out-hole run information that the upward signal that sent a UE by a LPN or channel measurement obtain.
Step 103, Macro receive the first out-hole run information of the LPN that a LPN sends.
In the present embodiment, after a LPN measures the first out-hole run information of a LPN, the first out-hole run information of a LPN is sent to Macro; Macro receives the first out-hole run information of the LPN that a LPN sends.
Step 104, Macro to Macro's and/or the first out-hole run information of a LPN carry out bias treatment, obtain bias treatment result.
In the present embodiment, Macro can add a bias in the first out-hole run information of Macro, and/or adds a bias in the first out-hole run information of a LPN.Wherein, added bias can be on the occasion of, also can be negative value.The result of bias treatment can make the LPN first out-hole run information after being biased be greater than the first out-hole run information of the Macro after being biased, so that a UE can select a LPN as its point of network attachment as far as possible.It is to be appreciated that the size of the bias increased and positive and negatively can to arrange as required.If need UE as much as possible to be attached to macro station, the LPN first out-hole run information after being biased also can be made to be less than the first out-hole run information of the Macro after being biased, and the present invention does not describe in detail this.
A kind of execution mode comprises: Macro is upper can be previously stored with bias list, stores the relevant information that Macro carries out needed for bias treatment in this bias list.In the present embodiment, store in bias list when the first out-hole run information of Macro is less than the first out-hole run information of a LPN, be left intact or increase the information of 0 bias.In addition, in bias list, any one information following is also stored:
When the first out-hole run information of Macro is more than or equal to the first out-hole run information of a LPN, need to increase by the first up bias to the first out-hole run information of Macro.Wherein, the first up bias is negative value, is mainly used in the first out-hole run information of Macro to turn down.
When the first out-hole run information of Macro is more than or equal to the first out-hole run information of a LPN, need to increase by the second up bias to the first out-hole run information of a LPN.Wherein, the second up bias be on the occasion of, be mainly used in the first out-hole run information of a LPN to heighten.
When the first out-hole run information of Macro is more than or equal to the first out-hole run information of a LPN, need to increase by the first up bias to the first out-hole run information of Macro and increase by the second up bias to the first out-hole run information of a LPN.
Based on above-mentioned, Macro can carry out bias treatment according to default bias list to the first out-hole run information, and the mode of concrete process comprises:
If the first out-hole run information of Macro is less than the first out-hole run information of a LPN, then Macro can not process the first out-hole run information of Macro, does not also carry out bias treatment to the first out-hole run information of a LPN.In other words, Macro by Macro's and/or the first out-hole run information of a LPN increase bias, but this bias is 0.
If the first out-hole run information of Macro is more than or equal to the first out-hole run information of a LPN, then Macro can adopt following arbitrary bias treatment mode:
Macro is according to " when the first out-hole run information of Macro is more than or equal to the first out-hole run information of a LPN; need to increase by the first up bias to the first out-hole run information of Macro " this information stored in bias list, the first out-hole run information of Macro itself is increased by the first up bias, keep the first out-hole run Information invariability of a LPN, the first out-hole run information of Macro after being biased and the first out-hole run information of a LPN are compared.The the first out-hole run information supposing Macro is x1, first up bias is a1, the first out-hole run information of the one LPN is y1, the first out-hole run information of the Macro after being then biased is (x1+a1), then as (x1+a1) < y1, select a LPN as point of network attachment; Otherwise, select Macro as point of network attachment.
Macro is according to " when the first out-hole run information of Macro is more than or equal to the first out-hole run information of a LPN; need to increase by the second up bias to the first out-hole run information of a LPN " this information stored in bias list, the first out-hole run information of the one LPN is increased by the second up bias, keep the first out-hole run Information invariability of Macro, the first out-hole run information of the LPN after making the first out-hole run information of Macro and being biased compares.The the first out-hole run information supposing Macro is x1, the first out-hole run information of the one LPN is y1, second up bias is a2, the first out-hole run information of the LPN after being then biased is (y1+a2), then as x1 < (y1+a2), select a LPN as point of network attachment; Otherwise, select Macro as point of network attachment.
Macro according to store in bias list " when the first out-hole run information of Macro is more than or equal to the first out-hole run information of a LPN, need to increase by the first up bias to the first out-hole run information of Macro and increase by the second up bias to the first out-hole run information of a LPN " this information, the first out-hole run information of Macro is increased by the first up bias, the first out-hole run information of the one LPN is increased by the second up bias, the first out-hole run value of the LPN after making the first out-hole run information of the Macro after being biased and being biased compares.As (x1+a1) < (y1+a2), select a LPN as point of network attachment; Otherwise, select Macro as point of network attachment.
Illustrate at this, Macro also can not carry out bias treatment according to bias list to the first out-hole run information, and carries out bias treatment directly according to Macro with the comparative result of the first out-hole run information of a LPN.
Step 105, Macro, according to bias treatment result, are selected LPN or Macro as the point of network attachment of a UE, are communicated to make a UE by point of network attachment.
Macro is to Macro's itself with after the first out-hole run information of a LPN carries out bias treatment, if the first out-hole run information of Macro is less than the first out-hole run information of a LPN, illustrate that the service of a LPN is better than Macro, therefore Macro is a UE selects a LPN as its point of network attachment, thus a UE is communicated by a LPN.If the first out-hole run information of Macro is greater than the first out-hole run information of a LPN, illustrate that the service of Macro is better than a LPN, therefore Macro selects Macro as the point of network attachment of a UE, thus a UE is communicated by Macro.
In the present embodiment, Macro selects the point of network attachment during uplink receiving of a LPN as a UE, the upward signal sent for responsible reception the one UE or channel, point of network attachment when simultaneously selecting a LPN to send as a UE descending, sends downstream signal or channel for being responsible for a UE.Or point of network attachment when point of network attachment when Macro selects the uplink receiving of Macro simultaneously as a UE and a UE descending sends, is responsible for upward signal that reception the one UE sends or channel and is responsible for sending downstream signal or channel to a UE.
In the present embodiment, by using out-hole run information, and by carrying out bias treatment to out-hole run information, making UE that LPN can be selected as point of network attachment, solving the problem that prior art cannot improve community from LPN or regional split gain.In addition, the present embodiment is not subject to the restriction of identical cell ID scene and different cell ID scene, more UE all can be made to select LPN as point of network attachment, improve the community from LPN or regional split gain under any scene.
The flow chart of the communication means that Figure 1B provides for second embodiment of the invention.As shown in Figure 1B, the method for the present embodiment comprises:
Step 111, Macro are that Macro itself and a LPN carry out downstream signal configuration, with make a UE according to the configuration of described downstream signal respectively to Macro's and the downstream signal of a LPN measure, with the first down-run survey information of the first down-run survey information and a LPN that obtain Macro.
In the present embodiment, be described for the LPN (i.e. a LPN) of the UE of in network (i.e. a UE) and the potential access of this UE, other UE select the process of point of network attachment identical therewith.Description about network see the description of step 101, can not repeat them here.
Macro is that a UE carries out downstream signal configuration, and Macro is received by downstream signal configuration instruction the one UE and measures which or which downstream signal, and indicates a UE measurement result to be returned.In the present embodiment, Macro is measured the downstream signal that a Macro and LPN sends by downstream signal configuration instruction the one UE.Wherein, Macro can indicate a UE to measure CSI-RS or USRS, and measurement result is returned to a Macro and LPN, but is not limited thereto.
After one UE receives the downstream signal configuration of Macro or LPN transmission, the instruction according to downstream signal configuration is measured the downstream signal that a Macro and/or LPN sends respectively, and measurement result is returned to a Macro and/or LPN.Wherein, the downstream signal measurement of a UE to Macro obtains the first down-run survey information of Macro, and the downstream signal measurement of a UE to a LPN obtains the first down-run survey information of a LPN.
Step 112, Macro receive the first down-run survey information of the Macro that a UE sends, and a LPN receives the first down-run survey information of the LPN that a UE sends.
Wherein, after a UE measurement obtains the first down-run survey information of Macro, the first down-run survey information of Macro is sent to Macro.After one UE measurement obtains the first down-run survey information of a LPN, the first down-run survey information of a LPN is sent to a LPN.
Step 113, Macro receive the first down-run survey information of the LPN that a LPN sends.
One LPN receives after a UE sends to its first down-run survey information, and its first down-run survey information is sent to Macro, and Macro receives the first down-run survey information of the LPN that a LPN sends.
Illustrate at this, the present embodiment receives the first respective down-run survey information separately for LPN and Macro and is described, but is not limited to this.Such as, a LPN can assist Macro to receive the first down-run survey information of the Macro of UE feedback, and the first down-run survey information receiving Macro is sent to Macro.Again such as, Macro can also assist a LPN to receive the first down-run survey information of a LPN of UE feedback.
Step 114, Macro to Macro's and/or the first down-run survey information of a LPN carry out bias treatment, obtain bias treatment result.
In the present embodiment, Macro can add a bias in the first down-run survey information of Macro, and/or adds a bias in the first down-run survey information of a LPN.Wherein, added bias can be on the occasion of, also can be negative value.The result of bias treatment should make the LPN first down-run survey information after being biased be greater than the first down-run survey information of the Macro after being biased, so that a UE can select a LPN as its point of network attachment as far as possible.
A kind of execution mode comprises: Macro is upper can be previously stored with bias list, stores the relevant information that Macro carries out needed for bias treatment in this bias list.In the present embodiment, store in bias list when the first down-run survey information of Macro is less than the first down-run survey information of a LPN, be left intact or increase the information of 0 bias.In addition, in bias list, any one information following is also stored:
When the first down-run survey information of Macro is more than or equal to the first down-run survey information of a LPN, need to increase by the first descending bias to the first down-run survey information of Macro.Wherein, the first descending bias is negative value, is mainly used in the first down-run survey information of Macro to turn down.
When the first down-run survey information of Macro is more than or equal to the first down-run survey information of a LPN, need to increase by the second descending bias to the first down-run survey information of a LPN.Wherein, the second descending bias be on the occasion of, be mainly used in the first down-run survey information of a LPN to heighten.
When the first down-run survey information of Macro is more than or equal to the first down-run survey information of a LPN, need to increase by the first descending bias to the first down-run survey information of Macro and increase by the second descending bias to the first down-run survey information of a LPN.
Based on above-mentioned, Macro can carry out bias treatment according to default bias list to the first down-run survey information, and the mode of concrete process comprises:
If the first down-run survey information of Macro is less than the first down-run survey information of a LPN, then Macro can not process the first down-run survey information of Macro, does not also carry out bias treatment to the first down-run survey information of a LPN.In other words, Macro by Macro's and/or the first down-run survey information of a LPN increase bias, but this bias is 0.
If the first down-run survey information of Macro is more than or equal to the first down-run survey information of a LPN, then Macro can adopt following arbitrary bias treatment mode:
Macro is according to " when the first down-run survey information of Macro is more than or equal to the first down-run survey information of a LPN; need to increase by the first descending bias to the first down-run survey information of Macro " this information stored in bias list, the first down-run survey information of Macro itself is increased by the first descending bias, keep the first down-run survey Information invariability of a LPN, the first down-run survey information of Macro after being biased and the first down-run survey information of a LPN are compared.The the first down-run survey information supposing Macro is x2, first descending bias is b1, the first down-run survey information of the one LPN is y2, the first down-run survey information of the Macro after being then biased is (x2+b1), then as (x2+b1) < y2, select a LPN as point of network attachment; Otherwise, select Macro as point of network attachment.
Macro is according to " when the first down-run survey information of Macro is more than or equal to the first down-run survey information of a LPN; need to increase by the second descending bias to the first down-run survey information of a LPN " this information stored in bias list, the first down-run survey information of the one LPN is increased by the second descending bias, keep the first down-run survey Information invariability of Macro, the first down-run survey information of the LPN after making the first down-run survey information of Macro and being biased compares.The the first down-run survey information supposing Macro is x2, the first down-run survey information of the one LPN is y2, second descending bias is b2, the first down-run survey information of the LPN after being then biased is (y2+b2), then as x2 < (y2+b2), select a LPN as point of network attachment; Otherwise, select Macro as point of network attachment.
Macro according to store in bias list " when the first down-run survey information of Macro is more than or equal to the first down-run survey information of a LPN, need to increase by the first descending bias to the first down-run survey information of Macro and increase by the second descending bias to the first down-run survey information of a LPN " this information, the first down-run survey information of Macro is increased by the first descending bias, the first down-run survey information of the one LPN is increased by the second descending bias, the first down-run survey value of the LPN after making the first down-run survey information of the Macro after being biased and being biased compares.As (x2+b1) < (y2+b2), select a LPN as point of network attachment; Otherwise, select Macro as point of network attachment.
Illustrate at this, Macro also can not carry out bias treatment according to bias list to the first down-run survey information, and carries out bias treatment directly according to Macro with the comparative result of the first down-run survey information of a LPN.

The flow chart of a kind of resource allocation methods that Fig. 2 A provides for fourth embodiment of the invention.As shown in Figure 2 A, the method for the present embodiment comprises:
Step 201, Macro obtain the interference value in network between every two LPN.
In the present embodiment, the interference strength between two between LPN can be divided into high interference or low interference by Macro.Concrete, Macro by interference threshold as the thresholding dividing high interference and low interference.Based on this, Macro can characterize interference strength between two between LPN by interference value.
Wherein, Macro can obtain the information relevant with interference of each LPN in network, and the information relevant with interference between two between LPN being compared, according to obtain with disturb the interference value of relevant acquisition of information between two between LPN.

A kind of execution mode as shown in Figure 2 B, comprising:
Step 2011a, Macro obtain the second out-hole run information of each LPN in network, and described second out-hole run information is that in network, each LPN configures the upward signal of UE transmission that it is measured to network side (i.e. Macro) or channel measurement obtains.
Wherein, Macro can select a UE, and the upward signal or the channel that configure this UE transmission are measured, and obtain the second out-hole run information of Macro.Each LPN in network also can select this UE according to the configuration of network side, and the upward signal sent this UE or channel are measured, and obtain the second out-hole run information of oneself.The second out-hole run information in the present embodiment and the first out-hole run information similar, if the UE that Macro and each LPN selects is a UE, and the upward signal sent or channel are also identical, then for the LPN in each LPN, the second out-hole run information is exactly the first out-hole run information.
After each LPN measures the second respective out-hole run information, the second respective out-hole run information is sent to Macro.Macro receives the second out-hole run information of each LPN oneself that each LPN sends.
Step 2012a, Macro in network between two the difference of the second out-hole run information of LPN and up difference threshold compare, judge whether the difference of the second out-hole run information of two LPN compared is less than or equal to up difference threshold; If judged result is yes, perform step 2013a; If judged result is no, perform step 2014a.
Wherein, up difference threshold presets, and its size is determined by concrete network environment, does not limit its occurrence.

Wherein, it is high interference that the first interference value shows between two LPN, or is potential high interference.
Step 2014a, Macro determine that between two LPN comparing, interference value is the second interference value.
Wherein, it is low interference that the second interference value shows between two LPN, or is potential low interference.
Another kind of execution mode as shown in Figure 2 C, comprising:
Step 2011b, Macro obtain the second down-run survey information of each LPN in network, and described second down-run survey information is that the pre-configured UE of network side (i.e. Macro) obtains the downstream signal measurement that each LPN sends.
Wherein, Macro can configure instruction UE by downstream signal and receives downstream signal and measure downstream signal, and report measurement results, the i.e. second down-run survey information of Macro.Each LPN in network also can select this UE according to the configuration of network side, and sends downstream signal to this UE.Before this, Macro receives the downstream signal of LPN and measures downstream signal by this UE of downstream signal configuration instruction, and report measurement results, by the second down-run survey information reporting of LPN to LPN.The second down-run survey information in the present embodiment and the first down-run survey information similar, if the UE that Macro and each LPN selects is a UE, and the downstream signal sent is also identical, then for the LPN in each LPN, the second down-run survey information is exactly the first down-run survey information.
The second respective down-run survey information is sent to Macro after receiving the second down-run survey information that UE reports by each LPN.Macro receives the second down-run survey information of each LPN oneself that each LPN sends.
Step 2012b, Macro in network between two the difference of the second down-run survey information of LPN and descending difference threshold compare, judge whether the difference of the second down-run survey information of two LPN compared is less than or equal to descending difference threshold; If judged result is yes, perform step 2013b; If judged result is no, perform step 2014b.
Wherein, descending difference threshold presets, and its size is determined by concrete network environment, does not limit its occurrence.
Step 2013b, Macro determine that the interference value between two LPN comparing is the first interference value.
Wherein, it is high interference that the first interference value shows between two LPN, or is potential high interference.
Step 2014b, Macro determine that the interference value between two LPN comparing is the second interference value.
Wherein, it is low interference that the second interference value shows between two LPN, or is potential low interference.
Another execution mode as shown in Figure 2 D, comprising:
Step 2011c, Macro obtain the positional information of each LPN in network.
Wherein, the positional information of LPN refers to the geographical position residing for LPN.
Step 2012c, Macro, according to the positional information of LPN between two in network, obtain the distance between two between LPN, and judge whether the distance between two between LPN is less than or equal to distance threshold; If judged result is yes, perform step 2013c; If judged result is no, perform step 2014c.
Wherein, distance threshold presets, and its size is determined by concrete network environment, does not limit its occurrence.
Distance between two between LPN refers to address location residing for two LPN, two LPN distance geographically obtained.Wherein, two LPN distance geographically embodies the relation between the coverage of two LPN to a certain extent.
Step 2013c, Macro determine that the interference value between two LPN comparing is the first interference value.
Wherein, it is high interference that the first interference value shows between two LPN, or is potential high interference.
Step 2014c, Macro determine that the interference value between two LPN comparing is the second interference value.
Wherein, it is low interference that the second interference value shows between two LPN, or is potential low interference.Step 202, Macro are divided in the rule of disturbance group according to two LPN that interference value is greater than default interference threshold, are divided in one or more interference group by the LPN in network.
After determining the interference relationships in network between each LPN, Macro is divided in the rule of disturbance group according to two LPN that interference relationships is high interference, divides into groups to LPN each in network.Wherein, the possibility of result of grouping comprises an interference group or multiple interference group.
The execution mode of the interference value between two between LPN is obtained in conjunction with above-mentioned Macro, interference value between two between LPN and default interference threshold can compare by Macro, be high interference between two LPN that interference value is greater than interference threshold, need to be divided in different interference groups.In the present embodiment, interference threshold is less than the first interference value and is greater than the second interference value.
Step 203, Macro, according to the rule of distributing orthogonal resource between disturbance group, are that a LPN distributes running time-frequency resource, pass through distributed running time-frequency resource communicate with a UE to make a LPN.
The flow chart of the another kind of resource allocation methods that Fig. 2 E provides for fourth embodiment of the invention.As shown in Figure 2 E, the method for the present embodiment comprises:
Step 201a, Macro obtain the interference value in network between every two LPN.
Step 201a see the description of step 201, can not repeat them here.
Two LPN that step 202a, Macro are less than or equal to interference threshold according to interference value are divided in same interference group, and two LPN that interference value is greater than interference threshold are divided in the rule of disturbance group, are divided in one or more interference group by the LPN in network.
In the present embodiment, two LPN that Macro is simultaneously less than or equal to interference threshold according to interference value are divided in same interference group, and two LPN that interference value is greater than interference threshold are divided in the rule of disturbance group, carry out packet transaction to the LPN in network.
Macro itself is divided in another interference group being different from above-mentioned one or more interference group by step 203a, Macro, or is divided into by Macro itself in an interference group in above-mentioned one or more interference group.
After by each LPN grouping, Macro also divides into groups to himself.
A kind of execution mode that Macro divides into groups to himself is: oneself is directly divided in an independently interference group by Macro, this means between Macro and all LPN it is strong jamming.
The another kind of execution mode that Macro divides into groups to himself is: Macro is according to the interference value between LPN each in Macro oneself and network, LPN and Macro being less than or equal to interference threshold according to interference value is divided in same interference group, LPN and Macro that interference value is greater than interference threshold is divided in disturbance group, divides into groups to oneself.This method of salary distribution means that Macro may be in same interference group with some LPN, belongs to low interference.
Step 204, Macro distribute orthogonal resource according between disturbance group, for LPN each in network distributes running time-frequency resource, pass through distributed running time-frequency resource communicate with the UE being attached to each LPN to make each LPN.
After each LPN and Macro is all assigned to different interference groups, Macro, according to the basic principle of distributing orthogonal resource between disturbance group, is each LPN and Macro distribution running time-frequency resource.
For between the LPN that potential interference is less or LPN and Macro, nonopiate running time-frequency resource can be used, also can use orthogonal running time-frequency resource.Wherein, in order to better support the durability of the running time-frequency resource between LPN or between LPN and Macro, improve running time-frequency resource utilance, between the LPN that potential interference is less or LPN and Macro to distribute nonopiate running time-frequency resource be a kind of preferred implementation.Therefore, the Macro of the present embodiment distributes nonopiate running time-frequency resource according in same interference group, for each LPN in same interference group distributes running time-frequency resource.
Composition graphs 1A-Fig. 1 C illustrated embodiment, the resource allocation methods of the present embodiment specifically refers to is selecting a LPN as its point of network attachment for a UE, when one LPN communicates with a UE, first by dividing interference group, according to the interference group at a LPN place, distributing nonopiate running time-frequency resource according in same interference group, and distribute orthogonal resource between disturbance group, is that a LPN distributes running time-frequency resource.

In addition, from above-mentioned, the time pattern of the present embodiment is with 8 milliseconds for the cycle, and the subframe that can to regard as by the cycle be 8 milliseconds forms.
The orthogonal time resource of the present embodiment mainly refers to Macro being running time-frequency resource used when each LPN or Macro dispatches, if above-mentioned very first time pattern is to the 8th time pattern.Nonopiate running time-frequency resource refers to each time slot being not yet assigned to orthogonal resource, these nonopiate time-frequencies can distribute to LPN or Macro in same interference group simultaneously, in addition, can also on the time slot distributing to nonopiate running time-frequency resource reserved part time interval resource, identical channel or signal is sent for Macro and LPN cooperation, such as, CRS, Physical Downlink Control Channel (enhanced/evolvedPhysical Downlink Control Channel, PDCCH), PDSCH, P/S-SS or USRS etc. are sent for Macro and LPN cooperation.

Wherein, a kind of orthogonal resource realized by above-mentioned time pattern as shown in Figure 2 F.
The resource allocation methods that the present embodiment provides, namely reduces the interference between potential each LPN or between LPN and Macro, ensures again to obtain channeling gain between these LPN or between LPN and Macro.
Further, in the above-described embodiments, Macro is existed between potential strongly disturbing LPN and Macro, soft orthogonal running time-frequency resource can also be adopted.So-called soft orthogonal running time-frequency resource refers to each LPN for being in Macro in disturbance group, Macro is that those LPN distribute the running time-frequency resource corresponding with the edge UE in Macro mutually orthogonal running time-frequency resource, and can be running time-frequency resource non-orthogonal with those LPN for the running time-frequency resource that the center UE in Macro is corresponding, also can be orthogonal running time-frequency resource.
Based on above-mentioned, Macro needs in advance each UE being attached to Macro to be divided into edge UE and center UE.Usually, Macro adopts signal to noise ratio (the Signal-to-Noise Ratio of each UE of the access Macro got, SNR) compare with signal-noise ratio threshold, or macro adopts Signal to Interference plus Noise Ratio (the Signal-to-Interference-Noise Ratio of each UE of access Macro, SINR) compare with Signal to Interference plus Noise Ratio thresholding, or macro adopts the channel quality of each UE of the access Macro got instruction (Channel Quality Indicator, CQI) thresholding is indicated to compare with channel quality, or the signal strength signal intensity of each UE of the access Macro got and signal strength threshold are compared, edge UE in Macro and center UE is determined according to comparative result.If the SINR of UE is greater than signal-noise ratio threshold, then UE centered by this UE, on the contrary this UE is edge UE.If the signal strength signal intensity of UE is greater than signal strength threshold, then UE centered by this UE, on the contrary this UE is edge UE.
If LPN and the Macro in above-mentioned Figure 1A-Fig. 1 C is in different interference groups, then Macro can be that the first LPN distributes the running time-frequency resource corresponding with the edge UE in Macro mutually orthogonal running time-frequency resource, to make a LPN be communicated with a UE by the running time-frequency resource that the running time-frequency resource corresponding with the edge UE in Macro that be assigned to is mutually orthogonal, reduce the interference between a Macro and LPN.Namely a LPN carries out scheduling of resource and the distribution of a UE on the running time-frequency resource be assigned to.
At present, 3GPP is discussing carrier aggregation (Carrier Aggregation, CA) technology, and CA passes through the polymerization of different carrier thus forms multi-carrier transmission, can improve network capacity further.Wherein, different carrier can be positioned at the continuous print of same frequency range or different frequency range or discrete frequency band.Such as, the application scenarios of the HetNet in a kind of CA provides the covering of Macro for carrier wave F1, and carrier wave F2 provides the covering of each LPN, and wherein mobility covers also based on carrier wave F1.Wherein, carrier wave F1 is 800 megahertzes (MHz) and 2GHz, and carrier wave F2 is 3.5GHz.But not providing Macro and LPN in the application scenarios of current HetNet is efficient communication method under multi-carrier case, is not more given in the method such as the Resourse Distribute under multi-carrier case, network attachment point selection.
For the problems referred to above, the embodiment of the present invention provides a kind of communication means of HetNet multi-carrier.The communication means of this multicarrier relates generally to how each UE in network selects point of network attachment, how to improve network capacity, how to reduce Communication Jamming, the solution of the how aspect problem such as Resources allocation.
First, the embodiment of the present invention provides a kind of network architecture of many running time-frequency resources, and is referred to as Ccell (aggregation cell) or Cnet (polymeric network) or Hicell (floored community).Wherein, " C " in Ccell or Cnet can be understood as covering (coverage), capacity (capacity), converges (coverged), cooperates (cooperative), gathers (collective), coordination (coordinated) or cloud (cloud) or coordinated multipoint transmission (CoMP); " Hi " in Hicell can be understood as layering (Hierarchical), super (Hyper) or mixing (Hybrid).Ccell or Cnet that the embodiment of the present invention provides or this network architecture of Hicell can be counted as and to be made up of cover layer and capacity layer or by basic communication layer with strengthen communication layers and form or be made up of general communication layers and private communication layer or by common communications layer and specific communication layer or be made up of common communication layer and private communication layer.That is, the network architecture under the multicarrier that the embodiment of the present invention provides, namely Ccell or Cnet or the Hicell network architecture are made up of two-layer.In order to without loss of generality, the embodiment of the present invention is by this two-layer called after first resource layer and Secondary resource layer respectively.
When multiple running time-frequency resource is made up of carrier resource, these corresponding two resource layers are first carrier layer and the second carrier wave layer, the carrier set that first carrier layer with the second carrier wave layer use or frequency range set different, and the power used also can difference.The embodiment of the present invention provides two kinds about the definition mode of first carrier layer and the second carrier wave layer.A kind of definition mode is: according to the size of carrier wave/frequency range that Macro and LPN uses, divide all carrier wave/frequency ranges, forms first carrier layer and the second carrier wave layer.Such as, first carrier layer cover layer is that carrier set 1/ frequency range set 1 forms, and the second carrier wave layer is that carrier set 2/ frequency range set 2 forms.Another kind of definition mode is: according to the power of Macro in used each carrier wave/frequency range, divide all carrier wave/frequency ranges that Macro and LPN uses, and forms first carrier layer and the second carrier wave layer.Such as, the first cover layer is coverage corresponding to low-power resource transmission, and the second cover layer is coverage corresponding to high power resource transmission.
If multiple running time-frequency resource layer is made up of sub-frame resources, these corresponding two resource layers are the first subframe layer and the second subframe layer, the sub-frame set that the first subframe layer with the second subframe layer use or subframe type different, and the power used also can difference.A kind of definition mode is: subframe be divided into normal sub-frames and ABS subframe or MBSFN sub-frame according to subframe type or fall lower powered ABS subframe or fall lower powered MBSFN sub-frame.Can use for the first subframe layer and fall lower powered ABS subframe or ABS subframe or fall lower powered MBSFN sub-frame.One or more in four kinds of subframes above can be used for the second subframe layer.Falling lower powered ABS subframe can be carry out Power Limitation to all channels except CRS and common signal channel and synchronizing channel or signal in ABS subframe, makes its transmitted power lower than certain threshold value.Typically at least need CSI-RS or/and DMRS carries out power reduction transmission.Such as Macro is configured to fall lower powered ABS subframe at the first subframe layer, and LPN is configured to ABS subframe at the first subframe layer.Macro and LPN is configured to normal sub-frames and/or MBSFN sub-frame at the second subframe layer.At the first subframe layer, Macro and LPN all can send signal or channel, such as ePDCCH, CSI-RS, USRS or PDSCH etc. to the UE being attached to Macro or LPN.Because Macro sends to fall lower powered ABS subframe in the subframe that LPN is corresponding, such as, serve for the UE for its channel quality better as high SINR, thus reduce the interference to the UE under LPN, make LPN obtain higher capacity at the first subframe layer.Wherein, above, " power " in described reduction power or " power " in power reduction refer to the transmitted power of Macro signal or channel on the first subframe layer.
If described multiple running time-frequency resource is made up of carrier resource and sub-frame resources, two corresponding resource layers can be the combinations of carrier wave layer and subframe layer.Such as, Macro is the power on each carrier wave according to the size of multiple years wave frequencies or Macro, multiple carrier wave is divided into first carrier layer and the second carrier wave layer, Macro is according to the type of each subframe, be the first subframe layer and the second subframe layer by multiple sub-frame division, Macro using the first subframe layer of first carrier layer and the second carrier wave layer as first resource layer, using the second subframe layer of the second carrier wave layer as Secondary resource layer.At the first carrier layer of first resource layer, Macro can reduce its transmitted power, can send ePDCCH, CSI-RS, USRS or PDSCH etc., or not send PDCCH or CRS.At the first subframe layer of the second carrier wave layer of first resource layer, Macro can reduce the transmitted power of channel except CRS, common signal channel and synchronizing channel or signal, such as, reduce the transmitted power of CSI-RS, make it lower than certain threshold value.Normal sub-frames or MBSFN sub-frame etc. can be configured at Secondary resource layer i.e. the second subframe layer of the second carrier wave layer communicate.
In addition, the communication means in Ccell or Cnet or Hicell also can be called floored community (LayerCell) or layering carrier wave (LayerCarrier) or carrier wave (FlexCarrier or Flexcarrier) or community (FlexCell or Flexcell) or the flexibly communication means of carrier aggregation net (Flexcarrier A Net or FCAN) or carrier wave/community (FlexC) (C wherein has identical implication with the C of Ccell above) etc. flexibly flexibly flexibly.
First illustrate that in HetNet application scenarios, UE selects the method for point of network attachment under multicarrier by specific embodiment below, still access a LPN for an a UE and UE in the following embodiments and be described.In addition, only illustrate for carrier wave in the following embodiments, frequency range and carrier wave have similar processing procedure, carrier wave layer and resource layer or subframe layer have similar processing procedure, the process of further various first resource layer is similar to the process of first carrier layer, and the process of various Secondary resource layer is similar to the second carrier wave layer.
The flow chart of the communication means that Fig. 3 A provides for fifth embodiment of the invention.As shown in Figure 3A, the method for the present embodiment comprises:
Step 301, Macro be the power on each carrier wave according to the size of multiple years wave frequencies or Macro, multiple carrier wave is divided into first carrier layer and the second carrier wave layer.
First, Macro according to the definition to first carrier layer and the second carrier wave layer, to a Macro and LPN multiple carrier waves that each LPN uses in a network divide.
When dividing with the first definition mode, Macro by multiple years wave frequencies respectively compared with the carrier frequency thresholding preset, the carrier wave that multiple carrier wave medium frequency is greater than carrier frequency thresholding is divided into first carrier layer, the carrier wave that multiple carrier wave medium frequency is less than or equal to carrier frequency thresholding is divided into the second carrier wave layer, and the transmitted power arranged on each carrier wave of Macro on first carrier layer is less than the transmitted power on each carrier wave of Macro on the second carrier wave layer, meet power requirement in definition to make first carrier layer and the second carrier wave layer.Wherein, carrier frequency thresholding can be arranged according to concrete network application adaptability by Macro, does not limit at this to its occurrence.
When dividing with the second definition mode, Macro transmitted power on each carrier compares with the power threshold preset by Macro, carrier wave corresponding to the power being less than or equal to power threshold is divided into first carrier layer, carrier wave corresponding for the power being greater than power threshold is divided into the second carrier wave layer.On the first carrier layer marked off in like fashion, the transmitted power of each carrier wave is less than the transmitted power of each carrier wave on the second carrier wave layer.
Wherein, the transmitted power of Macro on each carrier wave of first carrier layer is identical, and its transmitted power on each carrier wave of the second carrier wave layer is also identical.By the transmitted power of Macro on each carrier wave of first carrier layer, referred to as the power of Macro on first carrier layer, by the transmitted power of Macro on each carrier wave of the second carrier wave layer, referred to as the power of Macro on the second carrier wave layer.Wherein, the power of Macro on first carrier layer is less than its power on the second carrier wave layer.
Wherein, the power of each LPN on each carrier wave of first carrier layer, and its power on each carrier wave of the second carrier wave layer is all identical.By the power of each LPN on each carrier wave of first carrier layer, referred to as the power of each LPN on first carrier layer, by the power of LPN on each carrier wave of the second carrier wave layer, referred to as the power of each LPN on the second carrier wave layer.Namely the power of each LPN on first carrier layer is identical with its power on the second carrier wave layer.
Illustrate at this, the multiple carrier waves in the present embodiment are not limited to 2, and the carrier wave that is on each carrier wave layer can be more than 1 or 2 or 2.The carrier wave that each carrier wave layer comprises can be discrete frequency range, and such as, the carrier wave on first carrier layer comprises the frequency spectrum of 3.6GHz, and the carrier wave on the second carrier wave layer comprises the frequency spectrum of 800MHz and 900MHz.Wherein, because high frequency carrier is less than the coverage of low frequency carrier signal, therefore, generally using high frequency carrier as first carrier layer, for improving network capacity, and using low frequency carrier signal as the second carrier wave layer, in order to improve network coverage.
For the carrier bandwidths on first carrier layer or the second carrier wave layer or variable number, the traffic carrying capacity that can carry based on it or resource utilization or load are configured.Such as, on the second carrier wave layer traffic carrying capacity higher or resources occupation rate is higher or load is heavy time, can be the variable number that the carrier wave of the second carrier wave layer configures large bandwidth or more; When not having idle carrier resource available, also the carrier wave of first carrier layer can be configured in the carrier set of the second carrier wave layer, such as, the carrier wave of the first carrier layer of large bandwidth is configured to the carrier wave of the second carrier wave layer, and the carrier wave of the second carrier wave layer of little bandwidth is configured to the carrier wave of first carrier layer.Extreme case, all can also be configured to the carrier wave of the second carrier wave layer by all carrier resources.
Each UE, according to the speed of each UE in the ability of UE each in network and/or network, is divided into mobile UE group by step 302, Macro, UE ability 1 group and UE ability 2 groups.
Further, multicarrier is being divided into two carrier wave layers, after being responsible for promoting network capacity and network coverage respectively, Macro, by the capability reporting of each UE, obtains the ability of each UE, and by carrying out speed monitoring to each UE, obtains the speed of each UE; Then, according to ability and/or the speed of each UE, the UE under Ccell or Hicell network (i.e. the network at a LPN place) is divided into groups.In the present embodiment, UE is divided into UE ability 1 group, mobile UE group and UE ability 2 groups.A kind of method of ability for UE can be the type according to UE, and the Class1 specified in such as standard to type 8, thus can determine that this UE is ability 1 group of UE or ability 2 groups of UE.Different types can belong to different ability groups.Wherein, type is 6,7, and the UE of 8 belongs to Rel-10UE, and the UE of Class1 ~ 5 is the UE before Rel-10.A kind of point-score is using Class1 ~ 5 as ability 1 group, and the UE of type 6 ~ 8 is as ability 2 groups.Or standard newly defines UE type such as type 9 ~ N, N >=9 of Rel-11, then can using UE Class1 ~ 8 as ability group 1, and using UE type 9 ~ N as ability group 2.Now also ability 1 group can be called legacy UE group, and ability 2 groups is called non-legacyUE group.Another method of ability for UE is in conjunction with the type of UE and/or the type phase independently parameter with UE, such as whether supports ePDCCH and/or the measurement to the CSI-RS more than 1 non-zero (non-zero) through-put power to UE.For not supporting ePDCCH and/or to the UE of the measurement of the CSI-RS more than 1 non-zero (non-zero) through-put power UE as ability group 1; For supporting ePDCCH and/or to the UE of the measurement of the CSI-RS more than 1 non-zero (non-zero) through-put power UE as ability group 2.
Wherein, the UE that mobile UE group comprises refers to that speed is greater than the UE of certain translational speed (such as a certain speed threshold).The present embodiment can realize covering with reliable the high efficiency of UE each in LTE system by dividing different UE groups.
In the present embodiment, UE is divided in order to UE group 1, UE group 2 and mobile UE group, but is not limited thereto, such as can segment further UE ability, thus mark off more group.Can be relatively more flexible for the access of grouping UE on carrier wave layer, such as, when free remaining carrier resource or resource utilization are lower than certain value on the second carrier wave layer, according to the supportable of UE, corresponding UE group can be increased.
In order to realize the support to UE in UE ability 1 group, the second carrier wave layer of the present embodiment can comprise legacy carrier wave, to provide the backwards compatibility to UE in Legacy UE or ability 1 group.In order to realize the support to UE in UE ability 2 groups, the first carrier layer of the present embodiment can comprise non-legacy carrier wave or extra carrier type or legacy carrier wave, to reduce expense further, such as adopt reduce or do not send CRS, thus provide better performance for the UE of UE ability 2 groups.That is, be comparatively preferred embodiment: adopt the second carrier wave layer to be the service of mobile UE group or adopt the second carrier wave layer to be the 1 group of service of UE ability, and adopting first carrier layer to be the 2 groups of services of UE ability.
Wherein, adopt the second carrier wave layer be mobile UE group or for UE ability 1 group service time, for its service object can be in the Macro on the second carrier wave layer, also can be in certain LPN on the second carrier wave layer.When adopting first carrier layer to be UE ability 2 groups service, for the object of its service can be in the Macro on first carrier layer, also can be certain LPN be on first carrier layer.
Step 303, Macro judge whether a UE belongs to UE ability 2 groups, if judged result is no, perform step 304; If judged result is yes, perform step 305.
Based on above-mentioned, Macro judges that a UE is divided in UE ability 2 groups, is still divided in two other UE group, so that determine to provide Macro or LPN of the service carrier resource used to a UE.
Step 304, Macro control Macro communicate with a UE with each LPN, and perform step 306 on the second carrier wave layer.
When Macro judges a UE not in UE ability 2 groups, when namely a UE is in UE ability 1 group or mobile UE group, then Macro preferably control Macro itself communicate with a UE on the second carrier wave layer with each LPN, to improve the coverage of network." each LPN " described in this step mainly refers to the LPN that a UE accesses, and namely indicates a LPN on its second carrier wave layer, carry out the transmission of data or control channel with a UE.
Wherein, Macro controls each LPN on the second carrier wave layer, carries out communicating that mainly to comprise Macro be the resource that a UE distributes on the second carrier wave layer with a UE, and be advertised as the resource on the second carrier wave layer that a UE distributes to each LPN, thus enable a LPN and UE at the enterprising Serial Communication of corresponding resource.
Step 305, Macro control Macro communicate with a UE with each LPN, and perform step 306 on first carrier layer.
When Macro judges that a UE is in UE ability 2 groups, then Macro preferably control Macro itself and each LPN communicate with a UE on first carrier layer, to improve network capacity, reduce the power overhead of network." each LPN " described in this step equally mainly refers to the LPN that a UE accesses, and namely indicates a LPN to carry out the transmission of data or control channel with a UE on its first carrier layer.
Wherein, Macro controls each LPN on first carrier layer, carries out communicating that mainly to comprise Macro be the resource that a UE distributes on first carrier layer with a UE, and be advertised as the resource on first carrier layer that a UE distributes to each LPN, thus enable a LPN and UE at the enterprising Serial Communication of corresponding resource.
The present embodiment is by above-mentioned steps 301-step 305, under Macro and each LPN uses the scene of multiple carrier wave simultaneously, carry out with a UE communicate used carrier wave or frequency resource with each LPN, for the step of follow-up selection point of network attachment lays the foundation for a UE have selected Macro.
Step 306, Macro obtain Macro with the out-hole run information of a LPN, or Macro obtain the corresponding Macro of difference that UE sends with the down-run survey information of a LPN, or Macro obtain Macro with the out-hole run information of a LPN and corresponding Macro with the down-run survey information of a LPN.
Step 307, Macro to Macro's and/or the out-hole run information of a LPN carry out bias treatment, or to Macro's and/or the down-run survey information of a LPN carry out bias treatment, or to Macro's and/or the out-hole run information of a LPN and corresponding Macro's and/or a corresponding LPN's down-run survey information carry out bias treatment respectively.
Step 308, Macro, according to bias treatment result, are selected LPN or Macro as the point of network attachment of a UE, are communicated to make a UE by point of network attachment.
Above-mentioned steps 306-step 308 see the corresponding description of Figure 1A-Fig. 1 C illustrated embodiment, can not repeat them here.
If forward step 306 to by step 304, and perform subsequent step 307 and step 308, then, in operating process shown in step 306-step 308, Macro communicates with a UE on the second carrier wave layer with a LPN.Such as Macro and a LPN use the carrier wave on the second carrier wave layer and power to send downstream signal to a UE, and receive the feedback information of a UE.
If forward step 306 to by step 305, and perform subsequent step 307 and step 308, then, in operating process shown in step 306-step 308, Macro communicates with a UE on first carrier layer with a LPN.Such as Macro and a LPN use the carrier wave on first carrier layer and power to send downstream signal to a UE, and receive the feedback information of a UE.
In the present embodiment, first by Macro's and LPN's multiple carrier wave carry out layering, then the UE in network is divided into groups, after the UE group determining each UE place, according to the UE group at UE place for UE selects that Macro's communicate with used carrier wave and frequency resource with LPN, namely the carrier wave layer that UE accesses first is determined, then point of network attachment is being selected for UE, solve UE under multicarrier environment and select the problem of point of network attachment, achieve simultaneously and make UE as much as possible select LPN as point of network attachment, improve the community from LPN or regional split gain.
The flow chart of the communication means that Fig. 3 B provides for sixth embodiment of the invention.The present embodiment realizes based on Fig. 3 A illustrated embodiment, and as shown in Figure 3 B, the method for the present embodiment comprised before step 304:
Step 304a, Macro judge whether the resource utilization of Macro on the second carrier wave layer or the resource utilization sum of Macro and each LPN on the second carrier wave layer are greater than utilance thresholding; If judged result is no, perform step 304; If judged result is yes, perform step 305.
Wherein, the resource utilization sum of Macro and each LPN on the second carrier wave layer is obtained with the resource utilization addition of each LPN on the second carrier wave layer by the resource utilization of Macro on the second carrier wave layer.
Further, Macro can also judge whether the resource utilization of Macro on first carrier layer or the resource utilization sum of Macro and each LPN on first carrier layer are less than or equal to utilance thresholding; If if judged result is no, perform step 304; If judged result is yes, perform step 305.
Wherein, the resource utilization sum of Macro and each LPN on first carrier layer is obtained with the resource utilization addition of each LPN on first carrier layer by the resource utilization of Macro on first carrier layer.
Further, the method for the present embodiment, compared with Fig. 3 A illustrated embodiment, also comprised before step 305:
Step 305a, Macro judge whether the resource utilization of Macro on first carrier layer or the resource utilization sum of Macro and each LPN on first carrier layer are greater than utilance thresholding; If judged result is no, perform step 305; If judged result is yes, perform step 304.
Further, Macro can also judge whether the resource utilization of Macro on the second carrier wave layer or the resource utilization sum of Macro and each LPN on the second carrier wave layer are less than or equal to utilance thresholding; If judged result is no, perform step 305; If judged result is yes, perform step 304.
In the present embodiment, adjust according to the resource utilization of the Macro carrier wave layer used that to communicate with UE, achieve the priority of the grouping attached first carrier layer of UE and the second carrier wave layer to a certain extent, that is, although first carrier layer has lower expense, allow UE ability 2 groups of priority access first carrier layers, but when the resource utilization of first carrier layer reaches certain value or the resource utilization of the second carrier wave layer lower than certain value time, just UE ability 2 groups is carried out to the access of the second carrier wave layer; And for be also when only having the resource utilization of the second carrier wave layer to reach certain value the second carrier wave layer or the resource utilization of first carrier layer lower than certain value time, just UE ability 1 group or mobile UE are carried out to the access of first carrier layer, thus the resource of the second carrier wave layer can be made full use of, be also conducive to the advantage that first carrier layer plays low-power saving power resource.
This illustrate, in some cases, can only include above-mentioned steps 304a and step 305a one of them.
Further, except UE being divided into groups and select according to the access that UE group result carries out carrier wave layer, can also by dividing into groups to channel, and the access selection of carrier wave layer is carried out based on the group result of channel.Wherein, can divide into groups to channel based on business, such as, channel is divided into common signal channel (such as control channel) and dedicated channel (such as Traffic Channel or data channel).Adopt same running time-frequency resource transmission or employing broadcast mode or employing multicast to send common signal channel by Macro and LPN, can be sent on the second carrier wave layer by Macro and LPN.The mode being sent separately by Macro or sent separately by LPN or sent by Macro and LPN cooperation is adopted to send to dedicated channel.Further, can be non-broadcastedly to the transmission of dedicated channel, namely do not need all LPN and the Macro under Macro on identical running time-frequency resource one be all UE send.Wherein, to dedicated channel can by Macro independent or LPN separately or Macro and LPN cooperation send on first carrier layer.Here the method for classifying is carried out based on business, with the method not contradiction of carrying out based on UE classifying above.Such as, the UE of static/low speed can be applied to here based on the classification of business, and movement/control channel of UE at a high speed and data channel still can adopt the mode of broadcast to send.
The various embodiments described above or execution mode achieve under multicarrier environment, to make UE as much as possible select LPN as point of network attachment, below by the saving problem of the lifting and power resource that introduce multicarrier environment lower network capacity.
In embodiments of the present invention, for first carrier layer, the Upgrade Problem of what emphasis will solve is capacity.When the number of LPN in network exceed the dense degree of some or UE (referred to as focus) reach can be covered by LPN time, can reduce in the transmitted power of first carrier layer Macro, carry out the covering of newly-increased LPN to UE, not only can promote network capacity but also can saving power resource.
In embodiments of the present invention, the power bracket of regulation Macro on first carrier layer is: higher limit is the transmitted power (referred to as power) of Macro on the second carrier wave layer, and lower limit is the transmitted power of LPN.
Based on above-mentioned, seventh embodiment of the invention provides a kind of execution mode reducing the power of Macro on first carrier layer, and as shown in Figure 4, this execution mode comprises:
The path loss that each UE on the first carrier layer of step 401, Macro statistics access Macro is corresponding or RSRP or SINR, and from statistics, obtain greatest path loss or minimum RSRP or minimum SINR.
In the aforementioned embodiment, Macro determines according to the UE group at UE place the carrier wave layer that each UE accesses.Therefore in the present embodiment, Macro can according to the various signal of each UE of the first carrier layer of Macro and access Macro in communication process or channel, within a certain period of time, the information such as the path loss of each UE accessed under Macro first carrier layer or RSRP or SINR of pilot signal are added up.Then, Macro, from the path loss of each UE counted on or RSRP or SINR of pilot signal, obtains greatest path loss or minimum RSRP or minimum SINR.
Step 402, Macro, according to greatest path loss or minimum RSRP or minimum SINR, reduce the power of Macro on first carrier layer.
After acquisition greatest path loss or minimum RSRP or minimum SINR, Macro, based on the greatest path loss obtained or minimum RSRP or minimum SINR, reduces the power of Macro on first carrier layer.Such as, Macro can according to greatest path loss or minimum RSRP or minimum SINR, within the power bracket of Macro on first carrier layer, carry out dynamic conditioning, even can turn off the power (now Macro is 0 in the lower transmit power limit value of first carrier layer) of first carrier layer.
The present embodiment provides a kind of Macro according to according to greatest path loss or minimum RSRP or minimum SINR, and reduce the execution mode of the power of Macro on first carrier layer, this execution mode comprises:
It is the power of Macro on the second carrier wave layer that step 4021, Macro arrange the power upper limit value of Macro on first carrier layer, and to arrange the lower limit value of Macro on first carrier layer be the power of each LPN on first carrier layer or on the second carrier wave layer, or to arrange Macro lower limit value on first carrier layer be 0.Wherein, if the resource utilization of Macro on first carrier layer is within a certain period of time lower than certain value, then the power of Macro on first carrier layer is likely 0.
Step 4022, Macro carry out power grade division according to the power upper limit value of Macro on first carrier layer and lower limit value, and arrange the path loss thresholding or RSRP thresholding or SIRN thresholding that correspond to each power grade.
Concrete, its reducible power is divided into some grades by Macro, suppose the power bracket of Macro on first carrier layer to be divided into successively from higher limit to lower limit value PA, PB ..., PN, be namely divided into N number of power grade.Wherein, the power of Macro on the second carrier wave layer is Macro power upper limit value on first carrier layer, and that corresponding can be P
a, the power of each LPN on first carrier layer or the second carrier wave layer or performance number 0 are the lower limits of the power of Macro on first carrier layer, and that corresponding can be P
n.Then, if be benchmark with greatest path loss, then Macro arranges path loss thresholding corresponding to this N number of power grade respectively, and is designated as A
pL, B
pL..., N
pL.If with minimum RSRP for benchmark, then Macro arranges RSRP thresholding corresponding to this N number of power grade respectively, and is designated as A
rSRP, B
rSRP..., N
rSRP.If with minimum SINR for benchmark, then Macro arranges SINR thresholding corresponding to this N number of power grade respectively, and is designated as A
sINR, B
sINR..., N
sINR.
The path loss thresholding of greatest path loss with corresponding each power grade compares by step 4023, Macro, obtaining and be less than greatest path loss and differ minimum path loss thresholding with greatest path loss, is power grade corresponding to obtained path loss thresholding by the power setting of Macro on first carrier layer; Or, minimum RSRP compares with the RSRP thresholding of corresponding each power grade by Macro, obtaining and be greater than minimum RSRP and differ minimum RSRP thresholding with minimum RSRP, is power grade corresponding to obtained RSRP thresholding by the power setting of Macro on first carrier layer; Or, minimum SINR compares with the SINR thresholding of corresponding each power grade by Macro, obtaining and be greater than minimum SINR and differ minimum SINR thresholding with minimum SINR, is power grade corresponding to obtained SINR thresholding by the power setting of Macro on first carrier layer.
Concrete, if be benchmark with greatest path loss, the path loss thresholding of greatest path loss with corresponding each power grade compares, if greatest path loss > is A by Macro
pL, then Macro reduces its power on first carrier layer to P
a; If B
pL< greatest path loss < A
pL, then Macro reduces its power on first carrier layer to P
b; So, N is worked as
pLduring < greatest path loss, then Macro reduces its power on first carrier layer to P
n.
If with minimum RSRP for benchmark, minimum RSRP compares with the RSRP thresholding of corresponding each power grade, if B by Macro
rSRP< minimum RSRP < A
rSRP, then Macro reduces its power on first carrier layer to P
a; So, as minimum RSRP < N
rSRPtime, then Macro reduces its power on first carrier layer to P
n.
If with minimum SINR for benchmark, minimum SINR compares with the SINR thresholding of corresponding each power grade, if B by Macro
sINR< minimum SINR < A
sINR, then Macro reduces its power on first carrier layer to P
a; So, as minimum SINR < N
sINRtime, then Macro reduces its power on first carrier layer to P
n.
In above process, the initial power of Macro on first carrier layer is normally greater than power corresponding to greatest path loss or minimum RSRP or minimum SINR, therefore, the present embodiment arranges the power of Macro on first carrier layer according to greatest path loss or minimum RSRP or minimum SINR, the power of Macro on first carrier layer can be reduced, and by reducing the power of Macro on first carrier layer, achieve the object of hoist capacity, saving power resource.
Further, illustrating at this, reducing the power of each LPN on first carrier layer, with further saving power resource by adopting the method similar with reducing the power of Macro on first carrier layer.After power reduction, the power of each LPN on first carrier layer and on the second carrier wave layer can be different.

In the above-described embodiments, the cell ID of cell ID and Macro of each LPN on first carrier layer on first carrier layer can be identical, also can not be identical, the cell ID of cellID and Macro of each LPN on the second carrier wave layer on the second carrier wave layer can be identical, also can not be identical.But, the UE of high-speed mobile can be caused to switch frequently between Macro and LPN because LPN and Macro has different cell ID, switching can cause the consumption of network side resource and the reduction of UE side user impression frequently, therefore, switching frequency should be reduced as the second carrier wave layer promoting coverage as far as possible.
For the problems referred to above, the present embodiment can be arranged on each LPN on the second carrier wave layer and have identical cell ID with the Macro on the second carrier wave layer, thus avoids switching frequently.Now, on the second carrier wave layer, each LPN has the cell ID identical with Macro.
Further, each LPN that Macro can also be arranged on first carrier layer has identical cell ID with the Macro on first carrier layer.
Further, Macro is according to greatest path loss or minimum RSRP or minimum SINR, after reducing the power of Macro on first carrier layer, Macro is less to the interference of each LPN on first carrier layer, therefore, each LPN that Macro can be arranged on first carrier layer has different cell ID from the Macro on first carrier layer, and the cell ID arranged between each LPN is also different, now, on first carrier layer, different cell ID is used between each LPN and between each LPN and Macro, first carrier layer can obtain community or regional split gain completely.
In embodiment above, on the second carrier wave layer, each LPN have employed the cell ID identical with Macro and avoids switching frequently.But in real network, can as required on first carrier layer and each LPN on the second carrier wave layer carry out cell ID distribution, by trading off to identical cell ID and different cell ID, namely the mixing cell ID method of salary distribution is adopted to each LPN under Macro, so not only can take into account network performance but also can performance of handoffs be taken into account.Based on this, following examples of the present invention provide a kind of method for Macro under multicarrier environment and each LPN distribution cell ID.

Wherein, the process that the 3rd down-run survey information of the Macro on first carrier layer and the 3rd down-run survey information of the LPN of on first carrier layer compare comprises by Macro: first the 3rd down-run survey information of the Macro on first carrier layer is all measured thresholding with default second with the 3rd down-run survey information of the LPN compared and compared by Macro; If the 3rd down-run survey information of the Macro on first carrier layer and the 3rd down-run survey information of the LPN compared all are greater than the second default measurement thresholding, Macro continues comparing the Macro on first carrier layer with default second difference threshold with the difference of the 3rd down-run survey information of compared LPN; If the Macro on first carrier layer is less than default second difference threshold with the difference of the 3rd down-run survey information of compared LPN, Macro arranges different cell ID for the Macro on first carrier layer and the LPN that compares.
In other cases, Macro is that this LPN and Macro arranges identical cell ID.
The process that the 3rd down-run survey information of the LPN of two on first carrier layer compares comprises by Macro: first the 3rd down-run survey information of the LPN of two on first carrier layer is all measured thresholding with second and compared by Macro; If the 3rd down-run survey information of these two LPN on first carrier layer is all greater than the second measurement thresholding, Macro continues the difference of the 3rd down-run survey information of these two LPN on first carrier layer and default second difference threshold to compare; If the difference of the 3rd down-run survey information of these two LPN on first carrier layer is less than the second difference threshold, Macro is that these two LPN on first carrier layer arrange different cell ID.
In other cases, Macro is that these two LPN arrange identical cell ID.
Wherein, the downstream signal that Macro and LPN sends can be CSI-RS or USRS.
In the present embodiment, Macro is according to the measurement result of the upward signal sent UE or channel or the downstream signal feedback of each LPN and Macro that measures according to UE, by comparing with default measurement thresholding and difference threshold, for LPN and Macro carries out the distribution of cell ID on first carrier layer, make not only there is identical cell ID but also there is different cell ID on first carrier layer, namely the distribution of the cell ID to each LPN under Macro is completed by the mixing cellID method of salary distribution, reach the object not only network performance can taken into account but also performance of handoffs can be taken into account.
Further, Macro can be not only each LPN and the Macro distribution cell ID on first carrier layer by the mixing cell ID method of salary distribution, can adopt equally in this way for each LPN and Macro on the second carrier wave layer distributes cell ID.Wherein, Macro is that a kind of execution mode that each LPN and Macro on the second carrier wave layer distributes cell ID comprises by the mixing cell ID method of salary distribution: Macro obtains the 4th out-hole run information of the 4th out-hole run information of Macro on the second carrier wave layer and each LPN on the second carrier wave layer.Wherein, the 4th out-hole run signal of every two LPN on the second carrier wave layer is that the upward signal that sends same UE respectively of these two LPN or channel measurement obtain, and the Macro's on the second carrier wave layer is that the upward signal that sends same UE respectively of Macro and this LPN or channel measurement obtain with the 4th out-hole run information of any one LPN.
Then, the four out-hole run information of the 4th out-hole run information of the Macro on the second carrier wave layer with each LPN on the second carrier wave layer compares by Macro, if the 4th out-hole run information of the Macro on the second carrier wave layer is all greater than the default 3rd with the 4th out-hole run information of compared LPN measure thresholding, and Macro on the second carrier wave layer be less than default 3rd difference threshold with the difference of the 4th out-hole run information of compared LPN, Macro arranges different cell ID for the Macro on the second carrier wave layer and the LPN that compares.

Another kind of execution mode is: the four down-run survey information of Macro of Macro acquisition on the second carrier wave layer and the 4th down-run survey information of each LPN on the second carrier wave layer.Wherein, the 4th down-run survey signal of every two LPN on the second carrier wave layer is that same UE obtains the downstream signal measurement that two LPN of this on the second carrier wave layer send respectively, and the Macro's on the second carrier wave layer is that same UE obtains the downstream signal measurement that Macro and this LPN sends respectively with the 4th down-run survey information of any one LPN.

The 4th down-run survey information of every two LPN on the second carrier wave layer compares by Macro, if the 4th down-run survey information of these two LPN on the second carrier wave layer is all greater than the 4th measure thresholding, and the difference of the 4th down-run survey information of these two LPN on the second carrier wave layer is less than the 4th difference threshold, Macro is that two LPN arrange different cell ID.
The detailed realization of above-mentioned two kinds of execution modes see Fig. 5 A and Fig. 5 B, can not repeat them here.
The present embodiment completes the distribution of the cell ID to each LPN under Macro equally by the mixing cell ID method of salary distribution, reach the object not only can taken into account network performance but also can take into account performance of handoffs.
Illustrate at this, previous embodiments of the present invention is equally applicable to the scene that not only there is identical cell ID but also there is different cell ID.Illustrate to there are 6 LPN under supposing Macro, be respectively a LPN, the 2nd LPN, the 3rd LPN, the 4th LPN, the 5th LPN and the 6th LPN.2nd LPN, the 4th LPN and the 6th LPN are positioned at same interference group, and are there is potential strongly disturbing LPN with the LPN in another interference group, the 3rd LPN and the 5th LPN.Suppose that a LPN, the 3rd LPN have the cell ID identical with Macro with the 5th LPN, and the 2nd LPN, the 4th LPN have the cell ID different from Macro with the 6th LPN after cell ID distributes.Because the 2nd LPN, the 4th LPN have the cell ID different from Macro with the 6th LPN, it can obtain community or regional split gain.Soft orthogonal resource can be used for Macro, namely for the low speed UE meeting certain channel quality requirement under Macro, or SINR or signal strength signal intensity are higher than the UE (such as center UE) of certain thresholding, one LPN, the 3rd LPN, the 5th LPN and Macro adopt identical running time-frequency resource to transmit, such as a LPN, the 3rd LPN, the 5th LPN and Macro can use simultaneously the very first time pattern in Fig. 2 E to the 8th time pattern wherein any one or its combination transmit, thus obtain regional split gain.For the UE (such as edge UE) of SINR under Macro lower than certain thresholding, Macro can use the running time-frequency resource orthogonal with a LPN, the 3rd LPN, the 5th LPN to transmit data, such as, a Macro and LPN, the 3rd LPN, the 5th LPN use the carrying out of time patterns different in Fig. 2 E to transmit respectively.In addition, for high speed UE, can identical running time-frequency resource be used to carry out the transmission of data and control channel between Macro and the LPN with identical cell ID, obtain diversity gain, thus ensure the reliability of communication.
Based on above-mentioned, the scene of identical cell ID and different cell ID can be there is between each LPN and Macro on first carrier layer or on the second carrier wave layer simultaneously, LPN or Macro with different cell ID is sent respectively to specific CRS, PSS, SSS, PDCCH, PCFICH, PHICH, PDSCH, CSI-RS, USRS and ePDCCH of its coverage cell.Continue for a LPN, if a LPN has the cell ID different from other LPN and Macro, then a LPN needs specific CRS, PSS, SSS, PDCCH, PCFICH, PHICH, PDSCH, CSI-RS, USRS and ePDCCH of transmission the one LPN institute coverage cell.
Have the LPN of identical cell ID for Macro, the transmission means of its signal or channel has following several:
The first transmission means: Macro and LPN all sends identical CRS, and Macro and LPN all sends the combination of identical PDCCH, PCFICH, PHICH and PBCH one of them or its.For a LPN, that is, if a LPN has identical cell ID with Macro on first carrier layer or on the second carrier wave layer, then a Macro and LPN all sends CRS, PDCCH, PCFICH, PHICH and PBCH one of them or its and combines on first carrier layer, or a Macro and LPN all sends CRS, PDCCH, PCFICH, PHICH and PBCH one of them or its and combines on the second carrier wave layer.
The second transmission means: Macro and LPN all sends identical CRS, and Macro and LPN all sends the combination of identical PDCCH, PCFICH, PHICH, PBCH and PDSCH one of them or its.Wherein, PDSCH is based on CRS demodulation.For a LPN, that is, if a LPN has identical cell ID with Macro on first carrier layer or on the second carrier wave layer, then a Macro and LPN sends CRS, PDCCH, PCFICH, PHICH, PBCH and PDSCH one of them or its and combines on first carrier layer; Or a Macro and LPN sends CRS, PDCCH, PCFICH, PHICH, PBCH and PDSCH on the second carrier wave layer.
The third transmission means: Macro sends CRS, PDCCH and PBCH one of them or its combination, and LPN does not send above-mentioned channel/signal.For a LPN, that is, if a LPN has identical cell ID with Macro on first carrier layer or on the second carrier wave layer, then only have Macro on first carrier layer or on the second carrier wave layer, all send the combination of CRS, PDCCH and PBCH one of them or its, a LPN does not send.
4th kind of transmission means: Macro and LPN does not all send CRS or PDCCH.For a LPN, that is, if a LPN has identical cell ID with Macro on first carrier layer or on the second carrier wave layer, then a Macro and LPN does not all send CRS or PDCCH.
Further, for above-mentioned four kinds of transmission meanss, Macro and orthogonal resource can be used to send USRS and PDSCH on first carrier layer or on the second carrier wave layer with the LPN (such as a LPN) that Macro has an identical cell ID.
In above-mentioned four kinds of transmission meanss, if do not send CRS, then Macro and can use orthogonal resource on first carrier layer with the LPN (such as a LPN) that Macro has an identical cell ID or the second carrier wave layer send USRS and PDSCH, to obtain diversity gain.That is, Macro and can orthogonal resource be used to send USRS on first carrier layer or on the second carrier wave layer or on the second carrier wave layer with the LPN (such as a LPN) that Macro has an identical cell ID.Or, Macro and can orthogonal resource be used to send PDSCH on first carrier layer or on the second carrier wave layer or on the second carrier wave layer with the LPN (such as a LPN) that Macro has an identical cell ID.
In above-mentioned four kinds of transmission meanss, if do not send CRS, then Macro and can also use identical running time-frequency resource on first carrier layer with the LPN (such as a LPN) that Macro has an identical cell ID or the second carrier wave layer send USRS and PDSCH, to obtain spatial multiplex gains.That is, Macro and can also identical running time-frequency resource be used to send USRS on first carrier layer or on the second carrier wave layer with the LPN (such as a LPN) that Macro has an identical cell ID.Or, Macro and can also identical running time-frequency resource be used to send PDSCH on first carrier layer or on the second carrier wave layer with the LPN (such as a LPN) that Macro has an identical cell ID.
Wherein, USRS and PDSCH of corresponding same UE is identical; USRS and PDSCH of corresponding different UEs is generally different, and the precoding of such as USRS can be different, and the content of PDSCH carrying can be different.But have the LPN of identical cell ID for Macro with Macro, USRS and PDSCH sent is identical, if namely Macro sends USRS and PDSCH of certain UE, this LPN also can send USRS and PDSCH of this UE.
Further, control channel (ePDCCH) that is that can also adopt expansion for the UE of UE ability 2 groups or that strengthen carries out control channel transmission.The pilot tone based on DMRS can be used with PDCCH to carry out demodulation unlike ePDCCH, share the running time-frequency resource position shared by PDSCH with PDSCH, such as with Resource Block to (RB pair) for granularity carries out Resourse Distribute.EPDCCH can be the UE service of UE ability 2 groups at first carrier layer or the second carrier wave layer.
Such as, if a UE belongs to UE ability 2 groups, a LPN sends CRS and PDCCH on the second carrier wave layer, and first carrier layer sends ePDCCH.
Further, current LPN is main it is considered that omnidirectional antenna.The benefit of sectorization to increase the isolation between sector, improves the signal quality in single sector, increases the reusable resource in space.In order to obtain spatial gain further, LPN can be considered to carry out sectorization.Such as, LPN is divided into 3 sectors, 6 sectors; Or vertical plane cell splitting or horizontal plane cell splitting, to form the antenna coverage areas of more than 2 or 2, wherein, each overlay area has the main beam of oneself to cover.These antenna overlay area is sector.Macro is after being divided into first carrier layer and the second carrier wave layer by multiple carrier wave, Macro can also carry out any one sectorization process following:
Macro carries out sectorization process to LPN each in network on first carrier layer and/or on the second carrier wave layer.Wherein, because the power of LPN is smaller, on first carrier layer and the second carrier wave layer, se ctor partition is carried out to LPN simultaneously.Wherein, to LPN on first carrier layer and the sector the second carrier wave layer marking off equal number be a kind of Alternate embodiments, or, also can mark off the different sector of quantity.
Macro carries out sectorization process on Macro first carrier layer.
Macro carries out sectorization process on Macro first carrier layer, and on first carrier layer and/or on the second carrier wave layer, carries out sectorization process to LPN each in network.
Further, Macro is that identical or not identical cellID is distributed in the different sectors of each LPN in network, that is can have identical cell ID or different cell ID between these sectors.A kind of sectorization result schematic diagram that Fig. 6 A provides for eighth embodiment of the invention.Wherein, Macro does not carry out sectorization at first carrier layer, and each LPN is split into 3 sectors, and each sector has identical cellID.The another kind of sectorization result schematic diagram that Fig. 6 B provides for eighth embodiment of the invention.Wherein, Macro is split into 3 sectors at first carrier layer, and the value lower limit of its power is the power of each LPN, and higher limit is the power of Macro at the second carrier wave layer, and each LPN is split into 3 sectors, and each sector has different cell ID.Another sectorization result schematic diagram that Fig. 6 C provides for eighth embodiment of the invention.Wherein, Macro is split into 6 sectors at first carrier layer, and each LPN is split into 6 sectors, and is all there is identical or different cell ID in each sector.
Wherein, when sector number is greater than 4, Macro can distribute different cell ID for adjacent sectors, such as, realize by least arranging 2 cell ID the object that adjacent sectors uses different cell ID, thus reduces the interference between sector.
In addition, in Fig. 6 A-Fig. 6 C, LPN is split into the sector of same number at first carrier layer and the second carrier wave layer, but is not limited thereto, such as: Macro can by same LPN on first carrier layer and divide the sector of different number on the second carrier wave layer.
In above-mentioned each division result, Macro can for there is the LPN of identical cell ID sector between distribute orthogonal resource, to reduce interference.
Further, the difference in quality of downlink or uplink signal between two sectors can comparing the LPN with identical cell ID, when its difference is higher than certain thresholding, these two sectors are classified as resource multiplex collection, otherwise these two sectors are classified as the accurate orthogonal set of resource.Macro is that the LPN of resource multiplex collection uses multiplexing running time-frequency resource, such as, all use a time pattern in Fig. 2 E.Such as, if be positioned at a LPN of the second carrier wave layer, the 3rd LPN and the 5th LPN is classified as resource multiplex collection, uses identical time-domain resource between them.In like manner, if be positioned at the 2nd LPN of the second carrier wave layer, the 4th LPN and the 6th LPN is classified as resource multiplex collection, and they also use identical time-domain resource.Macro can use other time-domain resource.
Further, the sector downlink or uplink channel/signal quality of accurate for resource orthogonal set is sorted, for the UE of channel quality lower than certain value, as edge UE, between the LPN of the accurate orthogonal set of resource, distributes orthogonal running time-frequency resource.For the UE of channel quality higher than certain value, between the LPN of the accurate orthogonal set of resource, distribute multiplexing running time-frequency resource.
For LPN sectorization, Macro can be the CSI-RS configuration of each sector configuration particular sector, Macro obtains the down channel situation of each sector according to CSI-RS quality measurement feedback result, thus determining that UE is to the attachment of sector, this mode had both been applicable to LPN or Macro that the second carrier wave layer is also applicable to first carrier layer.Wherein, the description of the LPN accompanying by UE can select see UE in Figure 1A-Fig. 1 C illustrated embodiment the attaching process of each sector, is not described in detail in this.
