Background technology
At present, in order to improve the utilance of Radio Resource, usually in the residential quarter, adopt the power pool technology to share to realize power at intercarrier.As, suppose that each residential quarter all can dispatch M carrier wave, the Common transport channel (being called for short public affairs delivers a letter) that is used for the public breath of delivering a letter of transmission is configured in the TS0 time slot of main carrier, after adopting the power pool technology, allow main carrier TS0 time slot and descending pilot frequency time slot (DwPCH) in, to use total transmitting power of M carrier wave to carry out signal and launch, the coverage of breath thereby the public affairs that can increase the residential quarter are delivered a letter; Accordingly, (be called for short at the time slot that is used for service data transmission, business time-slot, as, TS2, TS3......TS6) adopt the power pool technology then to depend on the power demand of single carrier, be specially: the large covering of low capacity is the principal character at networking initial stage, this feature main manifestations is that number of users is less, the user distribution of each intercarrier is very uneven, because user distribution is at the diverse location of residential quarter, thereby the situation that really needs the residential quarter to adopt full power to transmit is actually rare, the situation that the transmitting power of each carrier wave reaches capacity simultaneously still less, therefore, in business time-slot, if when certain carrier wave covers deficiency owing to the reasons such as user present position cause, can use the transmitting power of other carrier waves to satisfy the demand of this customer service quality, at this moment, just can in the residential quarter, adopt the power pool technology to realize the distribution of transmitting power at intercarrier; At present, transmit power allocations between the business time-slot intercarrier mainly is that the expectation power according to each carrier wave distributes, namely when total transmitting power of M carrier wave can satisfy total expectation power of each carrier wave, total transmitting power is distributed according to corresponding expectation power at each intercarrier, and when total transmitting power of M carrier wave can not satisfy total expectation power of each carrier wave, if not enough problem appears covering in certain carrier wave, then guarantee other allocation of carriers to transmitting power satisfy under the prerequisite of the current user demand of corresponding carriers, with the demand pro-rata of remaining transmitting power according to each carrier wave, to reach the purpose of utilizing to greatest extent power resource.
At present, give tacit consent to auxiliary carrier wave and do not support channel configuration at the TS0 time slot, yet in order further to improve data transmission efficiency and to improve resource utilization, under the prior art, the TS0 time that begins to plan to be supported in auxiliary carrier wave configures code channel, accordingly, about the transmit power allocations problem of major-minor intercarrier at the TS0 time slot, but formulated following embodiment:
(1) major-minor intercarrier adopts the implementation in existing business time slot power pond to carry out the distribution of transmitting power at the TS0 time slot, namely according to the corresponding transmitting power of expectation power division of each carrier wave.
Yet employing scheme (1) needs dynamically to transmit the expectation power of each carrier wave, and this relates to all too many levels of system's operation, and flow process is complicated, has reduced Systems balanth.
(2) without under the antenna failure condition, configure each carrier wave and be no more than total transmitting power of all antennas of whole residential quarter in the transmitting power sum of TS0 time slot, and when antenna failure, configure auxiliary carrier wave and penetrate power at the TS0 time slot regardless of allocation.
Yet, after the employing scheme (2), when antenna failure, can not use auxiliary carrier wave at TS0 time slot bearer service data or the public affairs breath of delivering a letter, thereby reduce wireless resource utility efficiency.
(3) without under the antenna failure condition, configure each carrier wave is no more than whole residential quarter in the transmitting power sum of TS0 time slot total transmitting power, and when antenna failure, account for the ratio of main aerial number according to current effective antenna number, descend to carrying out equal proportion in the transmitting power of the public carrier wave of delivering a letter of TS0 time slot carrying.For example, suppose always to have eight antennas, its total transmitting power is 6w, and at the TS0 time slot, the transmitting power of the public carrier wave of delivering a letter of carrying is 4w, so, when two antennas broke down, at the TS0 time slot, the transmitting power of the public carrier wave of delivering a letter of carrying was dropped to 4 * 6/8=3W by equal proportion.
Yet, after the employing scheme (3), when antenna failure, can cause cell coverage area to dwindle, and then affect systematic function.
In sum, all support the situation of channel configuration at the TS0 time slot for major-minor carrier wave, existing scheme in each intercarrier distribution transmitting power is all undesirable, therefore, needs the corresponding carrier transmit power allocation scheme of redesign.

In the embodiment of the invention, network side apparatus can be base station controller (RNC), also can be the base station.
Based on technique scheme, in the embodiment of the invention, take assigned timeslot be the TS0 time slot as example, consult shown in Figure 2ly, network side apparatus is as follows for the detailed process of each the carrier wave configuration of transmit power that comprises in any one frequency range:
Step 200: network side apparatus determines that all carrier waves in any one frequency range in the public affairs that the carrying of TS0 time slot is public to be adopted when delivering a letter total transmitting power of delivering a letter, are designated as totalpower_cch.
In the present embodiment, when execution in step 200, the following operation of the concrete execution of network side apparatus:
S2000: network side apparatus is determined respectively each carrier wave in above-mentioned any one frequency range in the public affairs that the carrying of TS0 time slot is public to be adopted when the delivering a letter transmitting power of delivering a letter, and the public affairs of remembering any one carrier wave n transmitting power of delivering a letter is power_c
n, 1≤n≤N, N are the carrier number in any one frequency range.
In the present embodiment, when carrying out S2000, for any one carrier wave n (can be main carrier, also can be auxiliary carrier wave), network side apparatus configuration power_c
nConcrete mode as follows:
If current flow process relates to the public affairs changing process of delivering a letter, then network side apparatus need to be judged carrier wave n whether the actual bearer public affairs are delivered a letter at the TS0 time slot, because network side apparatus is had the ability and authority is dispatched Radio Resource, therefore network side apparatus can know whether carrier wave n is configured to have carried public affairs and delivers a letter, if, then according to carrier wave n in cycle that each public affairs of TS0 time slot are delivered a letter, length, offset parameter, add up (maximum cycle of discontinuous distribution) occurs in 128 subframes public affairs deliver a letter transmitting power and maximum, this maximum is configured to the power_c that carrier wave n adopts at the TS0 time slot
n, for example: carrier wave n in the TS0 time slot configuration P-CCPCH (cycle 4, length 4, skew 0,2 code channel transmitting power 25dbm), S-CCPCH (cycle 4, length 2, skew 0,2 code channel power 25dbm), FPACH (power 25dbm), then power_c
n=29.77dbm...... (the specific implementation flow process does not repeat them here for existing known technology), otherwise, with power_c
nBe configured to 0;
If current flow process does not relate to the public affairs changing process of delivering a letter, then network side apparatus is with the power_c of carrier wave n
nBe configured to 0.
The above-mentioned public affairs changing process of delivering a letter can comprise that residential quarter Establishing process, cell re-configuration process, frequency add flow process, frequency deletion flow process, public Establishing process, public reprovision flow process and public deletion flow process etc. that passes of passing of passing.
Network side apparatus can adopt aforesaid way to determine respectively the public affairs of each carrier wave of comprising in any frequency range transmitting power of delivering a letter.
S2001, the transmitting power addition of delivering a letter of the public affairs of each carrier wave that network side apparatus will obtain obtains public affairs deliver a letter total transmitting power, i.e. totalpower_cch.
For example, totalpower_cch=power_c
1+ power_c
2+ ... power_c
n+ ...+power_c
N, N is the carrier number in the frequency range, power_c
1, power_c
2, power_c
n, power_c
NBe respectively in the frequency range public affairs of each carrier wave transmitting power of delivering a letter.
Step 210: network side apparatus determines that all carrier waves in above-mentioned any one frequency range allow total transmitting power in the maximum of TS0 time slot, are designated as totalpower_ante.
In the present embodiment, during execution in step 201, network side apparatus need be determined the effective number of antennas of current reality (being the number of fault-free antenna), be designated as K, and the maximum transmitting power (for all carrier waves in any one frequency range) that allows of default single antenna, be designated as P_OUT, P_OUT represents the signal transmitting capacity of single antenna, surpass P_OUT, antenna just might burn, and then, network side apparatus multiplies each other the effective number of antennas of reality and the maximum transmitting power that allows of single antenna, to obtain maximum total transmitting power, the i.e. totalpower_ante=K*P_OUT of allowing.When effectively antenna number K changed, totalpower_ante need to recomputate.
Step 220: the public affairs that network side apparatus will obtain total transmitting power of delivering a letter allows total transmitting power to compare with maximum, and according to comparative result, pass priority principle based on public affairs, each carrier wave that configures respectively in above-mentioned any one frequency range allows transmitting power in the single antenna single carrier maximum of TS0 time slot.
The so-called public priority principle that passes namely refers to the preferential public transmitting power of delivering a letter that guarantees, based on this principle, in the embodiment of the invention, the concrete mode of network side apparatus execution in step 220 is as follows:
If comparative result is totalpower_ante≤totalpower_cch, namely represent based on current antenna situation, at the TS0 time slot, the public affairs that the maximum of each carrier wave allows total transmitting power to be not enough to undertake each carrier wave in above-mentioned any one frequency range total transmitting power of delivering a letter, therefore, should be respectively account for the deliver a letter ratio of total transmitting power of public affairs according to the public affairs of each carrier wave transmitting power of delivering a letter, corresponding carriers is suitably reduced in the maximum transmitting power that allows of the single antenna single carrier of TS0 time slot, thereby under the prerequisite that does not exceed the total transmitting power of maximum permission, the public affairs that farthest satisfy each carrier wave transmitting power of delivering a letter, for example, adopt following formula one to calculate any carrier wave n in the maximum transmitting power that allows of the single antenna single carrier of TS0, be designated as P
nThe single antenna single carrier:
Pn single antenna single carrier=P_OUT*power_c
n/ totalpower_cch formula one
For example, for 3 frequencies (i.e. 3 carrier waves) residential quarter:
Carrier wave 1 is at the maximum transmitting power=P_OUT*power_c that allows of the single antenna single carrier of TS0 time slot
1/ totalpower_cch;
Carrier wave 2 is at the maximum transmitting power=P_OUT*power_c that allows of the single antenna single carrier of TS0 time slot
2/ totalpower_cch;
Carrier wave 3 is at the maximum transmitting power=P_OUT*power_c3/totalpower_cch that allows of the single antenna single carrier of TS0 time slot;
If comparative result is totalpower_ante>totalpower_cch, namely represent based on current antenna situation, at the TS0 time slot, the public affairs that the maximum of each carrier wave allows total transmitting power to be enough to undertake each carrier wave in above-mentioned any one frequency range total transmitting power of delivering a letter, therefore, can be under the public affairs that preferentially satisfy each carrier wave be delivered a letter the prerequisite of transmitting power, remaining transmitting power is divided equally between each carrier wave, thereby the maximum transmitting power that allows of the single antenna single carrier that has improved each carrier wave, strengthened signal quality, adopt following formula two to calculate any carrier wave n in the maximum transmitting power that allows of the single antenna single carrier of TS0, be designated as P
nThe single antenna single carrier:
Pn single antenna single carrier=[power_cn+ (totalpower_ante-totalpower_cch)/N] * (1/K) formula two
For example, for 3 frequencies (i.e. 3 carrier waves) residential quarter:
Carrier wave 1 is at the maximum transmitting power=[power_c that allows of the single antenna single carrier of TS0 time slot
1+ (totalpower_ante-totalpower_cch)/3] * (1/K);
Carrier wave 2 is at the maximum transmitting power=[power_c that allows of the single antenna single carrier of TS0 time slot
2+ (totalpower_ante-totalpower_cch)/3] * (1/K);
Carrier wave 3 is at the maximum transmitting power=[power_c that allows of the single antenna single carrier of TS0 time slot
3+ (totalpower_ante-totalpower_cch)/3] * (1/K).
Certainly, above-mentioned formula one and formula two only for for example, in the practical application, can for concrete applied environment, pass priority principle based on public affairs and select voluntarily suitable account form under two kinds of comparative results of upper kind, do not repeat them here.
Based on above-described embodiment, network side apparatus can adopt same way as to configure the maximum transmitting power that allows of single antenna single carrier of each carrier wave in each frequency range, does not repeat them here.
In sum, in the embodiment of the invention, network side apparatus according to each carrier wave in the frequency range at the public affairs of assigned timeslot deliver a letter total transmitting power and the maximum comparative result that allows transmitting power, pass priority principle based on public affairs, configure the maximum transmitting power that allows of single antenna single carrier of each carrier wave, like this, expectation power in the time of needn't be according to the carriers carry different business is dynamically adjusted the maximum transmitting power that allows of single antenna single carrier of carrier wave, thereby reduced implementation complexity, guaranteed the stability of a system, simultaneously, when the part antenna breaks down, owing to having adopted public biography priority principle to configure the maximum transmitting power that allows of single antenna single carrier of each carrier wave, therefore, can the remaining antenna capabilities of maximum using, guaranteed the utilance of Radio Resource, farthest do not reduce cell coverage area, thereby effectively guaranteed systematic function.
On the other hand; to be configured complete after; when at every turn before the T0 time slot sends data; the power conservation treatment need to be carried out for each carrier wave in the base station; take a carrier wave as example; be specially: base station service based demand is carried out power control for this carrier wave; namely determine the single carrier transmitting power that this carrier wave adopts at code channel and the transmission of data of TS0 time slot carrying; then; to obtain again the single carrier transmit power allocations to each antenna, and make the single antenna single carrier transmitting power on each antenna be not more than the maximum transmitting power that allows of default single antenna single carrier.Like this; because each carrier wave can carry out the single-antenna power protection according to the maximum transmitting power that allows of the single antenna single carrier of each comfortable TS0 time slot; therefore; can guarantee that each carrier wave can not surpass the maximum transmitting power that allows of single antenna in the single-antenna transmission power sum of TS0 time slot; be P_OUT, thereby guaranteed the safety of antenna.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
