Description
Technical field
The present invention relates to be applicable to the Poewr control method of mobile communication system, especially, relate to transmission power control apparatus and the method thereof using reverse channel quality indicator and confirm designator.
Background technology
In radio communication, channel circumstance changes according to the position excursion of portable terminal.Therefore, preferably, revise this modulation and encoding scheme to be suitable for the channel quality of each situation.
About a modulation scheme is set, when this channel quality was good (that is, less interference), this communication system can be used the modulation that allows high-speed data transfer, such as the PSK (phase shift keying) of QAM (quadrature amplitude modulation) and M unit.But, be that it can use the modulation as jamproof BPSK (binary phase shift keying) under the situation of difference at channel quality.
About an encoding scheme is set, when this channel quality when being good, less redundancy (therefore, high code rate) is admissible, makes data to transmit with higher data speed.But when this channel circumstance was difference, this chnnel coding was carried out with more redundancy (lower code rate), made data to transmit with lower data rate.
For the variation according to this channel quality suitably changes this modulation and encoding scheme, need information about current channel quality.Forward channel quality is measured by portable terminal, and is sent to the base station via reverse channel quality indication channel (R-CQICH).Should be noted that this term reverse channel is expressed as derives from portable terminal and is transmitted to network, such as the communication of base station.
H-ARQ (mixed automatic retransmission request) is the method that a kind of mode with ARQ (re-send request may automatically) and FEC (forward error correction) combination is used to improve reliability and throughput.If a kind ofly there is mistake in ARQ in this transmission information, before receiving faultless information, be used for improving the method for transmission reliability in the mode that needs are retransmitted identical information.And FEC is a kind of method that is used for improving in the mode of correcting the mistake that has occurred during the transmission reliability.
During good channel quality, the number of times of the mistake in the information of this reception is low.Therefore, need to use ARQ to retransmit, can keep the reliability of the information of this reception whereby.But during the channel quality of difference, number of times wrong in the information of this reception is high.If use the ARQ that does not have FEC, it can cause the increase of number of retransmission.Therefore, because ARQ does not have any error correction feature, the throughput of this system will be lowered.
Because such problem can solve by FEC, proposed to use this H-ARQ system of ARQ and FEC.As a kind of H-ARQ, there is this IR (redundancy that increases progressively) system.In this IR system, transmitter side primitively sends with high code rate coded data, and it has the redundant bit of smallest number.If the vicious data of this receiver side receiving belt, then it needs to retransmit.Need in response to this, this transmitter side sends extra redundant bit, and this bit is caused by low rate coding.
Data and this redundant bit that the receiver side combination has received with decoding.In this case, the bit of this repeating transmission will compensate the previous grouping that sends.
In the HARQ of wireless communication system system, there is or does not exist mistake in the grouping that portable terminal decoding receives with inspection, and should feed back an ACK (affirmations) or NAK (denying) signal to the base station according to this check result.This packet is retransmitted in the base station that has received this NAK signal.With the grouping of this repeating transmission of decoding and the grouping of transmission primitively, this portable terminal has a diversity or coding gain by combination.This ACK/NAK signal that sends this base station from this portable terminal to is transmitted to this base station via reverse acknowledgement channel (R-ACKCH).
In typical wireless communication system, the specified attribute gain (nominal attribute gain) that is used for R-ACKCH is set to-3dB.In the process of implementing, determined that this gain was set up low for appropriate ACK operation.In other words, the current specified attribute gain that is used for R-ACKCH makes that false alarm probability (even when this transmitter did not send anything on R-ACKCH, this base station receiver detected the probability of ACK) is too high, causes a large amount of RLP to retransmit.
In order to discern this problem, under awgn channel, carry out simulation (simulations) by means of the current specified adjustment yield value of R-ACKCH.The 9600bps R-FCH that this simulation is used on R-ACKCH carries out.This pilot level is power control, makes and can realize 1%PER for R-FCH.
In Fig. 1, lines 2 are represented when ack signal is sent out, the CDF of demodulator output.Lines 4 are when this transmitter does not send anything, the complementary CDF of demodulator output.Lines 6 are when the NAK signal is sent out, the complementary CDF of demodulator output.
For the ease of explaining, can define following probability.
P
A-N: this ack signal is mistakenly detected as the probability of NAK.
P
N-A: this NAK signal is mistakenly detected as the probability of ACK.
P
NO-A: even when this mobile radio station did not send anything on R-ACKCH, this receiver detected the probability of ack signal.
In this example, suppose that a threshold value is given to the output of this base-station demodulator, so that ACK or NAK are detected in this base station.Should be noted that because this base station behavior may be identical for these two kinds of situations " no signal " do not need to come with " NAK " difference.Be used for determining that the criterion of this threshold level is with this P
A-NAnd P
N-AKeep below certain level.The selection of this level should be to realize relatively.But, 0.01 P
A-NSeemingly reasonably select.From Fig. 1, threshold value P hereto
N-ABe 0.001, it is seemingly very rational.But it changes into (turns out) P
NO-ABe 0.3, it is that to be used for appropriate operation be high bit.The P that this is high
NO-ACan cause some wrong incident.
Because this false alarm on R-ACKCH, this wrong incident can be explained as follows.When portable terminal was fully lost the forward packet data control channel that it is provided, this portable terminal can not send any signal on this R-ACKCH.About 30% for these situations, this base station judges that mistakenly ack signal is sent from this portable terminal, and will utilize the new grouping of ARQ channel to handle, and causes the RLP layer for that packet retransmission.Therefore suggestion needs modification to be used for this channel gain (that is through-put power) of R-ACKCH to address this problem.
The through-put power of R-CQICH is used the R-CQICH power adjustment gain and the R-ACKCQICH gain of pilot power (RLGAIN_ACKCQICH_PILOT) is determined.This R-CQICH power adjustment gain is sent to each portable terminal respectively from the base station.And, sent to all portable terminals from this base station usually for this R-ACKCQICH gain of pilot power.
Similarly, the through-put power of R-ACKCH is used the R-ACKCH power adjustment gain and determines for the R-ACKCQICH gain of pilot power (RLGAIN_ACKCQICH_PILOT).This R-ACKCH power adjustment gain is individually sent to each portable terminal from the base station.And, sent to all portable terminals from this base station usually for this R-ACKCQICH gain of pilot power.
As what in description above, mention, in the process of each of determining this R-CQICH and R-ACKCH through-put power, use this R-ACKCQICH gain usually for pilot power (RLGAIN_ACKCQICH_PILOT).But because used this common factor (RLGAIN_ACKCQICH_PILOT) in the process of determining this R-CQICH and R-ACKCH through-put power, following problem is inevitable.
For all portable terminals in a sub-district, the through-put power that R-ACKCH may take place needs to increase, but the situation that the through-put power of R-CQICH need remain unchanged.In this case, this R-ACKCH power adjustment gain should be sent to all portable terminals in this sub-district respectively.
This is to send portable terminals all in the sub-district to because if be used an Overhead Message (overhead message) for this R-ACKCQICH gain of pilot power (RLGAIN_ACKCQICH_PILOT), and the through-put power of this R-CQICH and the through-put power of R-ACKCH are increased.
For example, in the process that detects ACK/NAK, this base station uses the received power of this R-ACKCH to carry out threshold test.Therefore, under the too little situation of the through-put power of this R-ACKCH, this base station can detect no-signal as NAK mistakenly.If this R-ACKCQICH gain for pilot power (RLGAIN_ACKCQICH_PILOT) is transmitted to all portable terminals to address this problem, the through-put power of this R-CQICH is unnecessarily increased so that inefficient.Simultaneously, if this base station sends to this each portable terminal with this R-ACKCH power adjustment gain, the message load that then sends this portable terminal to increases, and this corresponding transmission course becomes complicated in the extreme.
Summary of the invention
Therefore, the present invention proposes the transmission power control method of a kind of R-CQICH (reverse channel quality indication channel) and R-ACKCH (reverse acknowledgement channel), it has been eliminated basically because the limitation and the caused one or more problems of shortcoming of correlation technique.
