In the embodiment of the present invention, the judgement of Base Band Unit to the position attaching relation of the terminal in compass of competency and extension unit can be, but not limited in the following ways.
Base Band Unit is before the current scheduling moment arrives, based on the cycle of setting, the judgement of the terminal in execution compass of competency and the position attaching relation of extension unit, and based on the extension unit that each terminal in the position attaching relation determination compass of competency obtained accesses.Certainly, the extension unit that at least one terminal of current scheduling moment uplink scheduling accesses can be determined.
Particularly, within the cycle of setting, Base Band Unit, according to ascending resource scheduling result, determines the ascending resource that any one terminal in compass of competency is corresponding;
When the scheduling instance of ascending resource corresponding to any one terminal above-mentioned arrives, open at least one extension unit, receive the data that any one terminal above-mentioned reports based on the ascending resource of described correspondence;
Base Band Unit is resolved the data received, and by the position attaching relation of any one terminal above-mentioned in analysis result determination compass of competency and extension unit.
Be described in detail below in conjunction with the decision procedure of embody rule scene to the position attaching relation of above-mentioned terminal and extension unit.
As shown in Figure 2 b, suppose that current area connects three extension units by a Base Band Unit and forms, be respectively extension unit 1, extension unit 2 and extension unit 3, worked in coordination with covering by these three extension units.
Assuming that the terminal in the compass of competency of current area has 6, respectively: UE0, UE1, UE2, UE3, UE4 and UE5, Base Band Unit can determine the position attaching relation of all terminals and extension unit in compass of competency within the cycle of setting, only be introduced for UE0 and UE1 below, according to a certain scheduling rule, for the terminal scheduling in the compass of competency of community resource distribution as shown in Figure 2 b.The scheduling instance corresponding for the ascending resource of UE0 distribution is T1, T5 and T6, and the scheduling instance that the ascending resource for UE1 distribution is corresponding is T3, T8 and T9.
For UE0, in the T1 moment, only open extension unit 1, extension unit 2 and extension unit 3 are closed, and Base Band Unit receives return data, resolves, if parse the data of UE0, then determine that the position of UE0 belongs to extension unit 1 to return data.

In the T6 moment, only open extension unit 3, extension unit 1 and extension unit 2 are closed, and Base Band Unit receives return data, resolves, if parse the data of UE0, then determine that the position of UE0 belongs to extension unit 3 to return data.
In like manner, for UE1, in the T3 moment, only open extension unit 1, extension unit 2 and extension unit 3 are closed, and Base Band Unit receives return data, resolves, if parse the data of UE1, then determine that the position of UE1 belongs to extension unit 1 to return data.
In the T8 moment, only open extension unit 2, extension unit 1 and extension unit 3 are closed, and Base Band Unit receives return data, resolves, if parse the data of UE1, then determine that the position of UE1 belongs to extension unit 2 to return data.
In the T9 moment, only open extension unit 3, extension unit 1 and extension unit 2 are closed, and Base Band Unit receives return data, resolves, if parse the data of UE1, then determine that the position of UE1 belongs to extension unit 3 to return data.
It should be noted that, the mode of Base Band Unit of the present invention to the judgement of the position attaching relation of the terminal in compass of competency and extension unit is not restricted, not only can adopt aforesaid way, can also realize based on prior art small area identification code (CELLID) positioning mode, multiple cell relay positioning map matching method and many CELLID colocated method.
Base Band Unit periodically updates the position attaching relation of terminal in compass of competency and extension unit, and Base Band Unit at judgement extension unit when effective transfer resource in current scheduling moment, utilize up-to-date position attaching relation.
Base Band Unit also can obtain the resource allocation result of at least one terminal above-mentioned according to the dispatch situation in current scheduling moment, the ascending resource that resource allocation result and terminal took in the current scheduling moment.
Base Band Unit is according to the positioning result of at least one terminal above-mentioned obtained and resource allocation result, the effective transfer resource on the extension unit that at least one terminal above-mentioned accesses can be determined, and, the effective transfer resource on all extension units in whole compass of competency can be determined further.
Particularly, at least one extension unit that Base Band Unit accesses at least one terminal above-mentioned, by in whole ascending resources of at least one extension unit above-mentioned, the ascending resource at least one terminal distribution above-mentioned is defined as the effective transfer resource of at least one extension unit above-mentioned in the current scheduling moment;
Base Band Unit is by whole ascending resources of at least one extension unit above-mentioned, and other ascending resources except effective transfer resource are defined as the failed transmission resource of at least one extension unit above-mentioned in the current scheduling moment;
Whole ascending resources in the above-mentioned extension unit do not accessed are defined as the failed transmission resource of the above-mentioned extension unit do not accessed in the current scheduling moment by the extension unit that Base Band Unit does not access at least one terminal above-mentioned in the extension unit in compass of competency.
Wherein, effective transfer resource is in whole ascending resources of extension unit, resource shared by dispatch terminal, then according to scheduling result, only on effective transfer resource of extension unit, just carry the signal transmission of terminal, can think to make an uproar in the end at the signal of failed transmission transmitted over resources.

Base Band Unit controls the extension unit that in the extension unit in compass of competency, at least one terminal above-mentioned does not access, and is reset by the signal that whole ascending resource transmits.
Namely, the extension unit that Base Band Unit accesses for the terminal of current scheduling moment uplink scheduling, effective transfer resource carries out the transmission of upward signal, turns off the signal in failed transmission resource.Like this, only transmit useful signal, the end noise cancellation signal in failed transmission resource is reset, effectively inhibits the end to make an uproar.
For the extension unit that the terminal of non-present scheduling instance uplink scheduling accesses, all ascending resources are all failed transmission resource, namely turn off the signal on void in whole transfer resource, like this, remove the transmission of end noise cancellation signal further, inhibit the end to make an uproar greatly.
So far, the method for uplink signal transmissions that the embodiment of the present invention provides is introduced complete.
Below in conjunction with concrete application scenarios, the embodiment of the present invention is further described in detail.
Consult shown in Fig. 4, for the network architecture of novel room subsystem in the embodiment of the present invention, in figure, BBU represents Base Band Unit, RRU represents extension unit, for distinguishing different extension units, adopts RRUabc to represent some extension units, wherein, a represents the call number of EU (i.e. expanding element), and b represents the call number of Port on EU (i.e. port), and c represents the numbering of different RRUs on same EU same port.Such as, RRU013 represents, the call number of the expanding element at this extension unit place is 0, and the call number of port is 1, is numbered 3.
In embodiments of the present invention, BBU, EU0, RRU000, RRU001, RRU002, RRU003, RRU004, RRU005, RRU006, RRU007, RRU010, RRU011, RRU012, RRU013, RRU014, RRU015, RRU016, RRU017 is adopted to work in coordination with the covering of this community.Wherein, adopt above-mentioned 16 RRU to carry this cell signal respectively, carry out degree of depth covering.
Upper 8 RRU connected of EU0, port0 adopt the mode of cascades superposition by port0 by signal gathering to EU0; After upper 8 extension units connected of EU0, port1 adopt the mode of cascade superposition to be superposed by the signal on port0 and port1 to EU0, EU0 by signal gathering by port1, send to BBU.
The data that final BBU resolves are the superposed signal on 16 RRU, if directly sent by the signal on each RRU, so, make an uproar and also superpose in the end on 16 RRU, the end of causing lifting of making an uproar is 12db, makes signal-to-noise ratio degradation 12db, has a strong impact on communication quality.
And in the embodiment of the present invention, by judging the RRU at the terminal place of current scheduling, resource terminal in RRU taken is defined as effective transfer resource, only on effective transfer resource, transmit upward signal.Concrete example explanation below.

Because UE3 belongs to RRU003, therefore by RRU003 frame number be 100, subframe numbers be 3 subframe on RB20-RB50 be defined as effective transfer resource, other RB are failed transmission resource;
Because UE6 belongs to RRU016, therefore by RRU0016 frame number be 100, subframe numbers be 3 subframe on RB80-RB99 be defined as effective transfer resource, other RB are failed transmission resource;
By RRU001, RRU002, RRU004, RRU005, RRU006, RRU007, RRU010, RRU011, RRU012, RRU013, RRU014, RRU015, RRU017 frame number be 100, subframe numbers be 3 subframe on whole ascending resources be defined as failed transmission resource.
Wherein, can think that the signal transmitted on effective transfer resource is useful signal, be noise signal at the signal of failed transmission transmitted over resources.
Base Band Unit controls 16 extension units, only on effective transfer resource, transmits upward signal.Be specially:
Base Band Unit control RRU000 frame number be 100, subframe numbers be 3 subframe on only open the transmission that RB0-RB9 carries out upward signal, by other RB signal reset; And,
