移动台发射功率的控制方法和装置 The mobile station transmission power control method and apparatus

技术领域 FIELD

[0001] 本发明涉及通信技术领域,特别涉及一种移动台发射功率的控制方法和装置。 [0001] The present invention relates to communication technology, and particularly relates to a method and apparatus for controlling transmission power of a mobile station. 背景技术 Background technique

[0002] 传统话音采用一个时隙给一个用户使用的分配方式,随着用户数量的不断增加,需要在相同的资源上承载更多路的话音,因此出现了在一个时隙和ARFCN(Absolute RadioFrequency Channel Number,绝对频点号)上复用多个用户的技术,如MUROS (Multi-User ReuseOne Slot,多用户复用同一时隙)技术,可以在固定的载频和频谱上获得容量的显著增加。 [0002] traditional voice mode using a time slot assigned to one user, as the number of users is increasing, the need for more voice bearer channel on the same resources, resulting in the (Absolute RadioFrequency in one slot and ARFCN increased significantly Channel number, the absolute frequency point number) with a plurality of users multiplexed on the technology, such as MUROS (multi-user ReuseOne slot, multi-user multiplexing in the same time slot) technique, the capacity can be obtained at a fixed carrier frequency spectrum and .

[0003] 参见图1,MUROS在一个时隙上复用两个用户MS(Mobile Mation,移动台)1 和MS2,且MUROS提供两个子信道,每个MS占用一个子信道,子信道通过正交或近似正交的训练序列来区分。 [0003] Referring to Figure 1, in a slot MUROS multiplexing two users MS (Mobile Mation, the mobile station) 1 and MS2, and provide two MUROS sub-channels, each MS occupies one subchannel, subchannel orthogonal training sequence or approximately orthogonal to distinguish. 在下行方向,BTS(Base Station Subsystem,基站子系统)发送两路GMSK(GaussianMinimum Shift-frequency Keying,高斯最小频移键控)信号,产生类QPSK(Quadrature PhaseShift Keying,四相相移键控)信号,MS通过相互正交的训练序列和增强的干扰消除技术,将不属于自己的信号,当作干扰信号进行消除,从而解出属于自己的一路信号。 In the downstream direction, BTS (Base Station Subsystem, BSS) transmitting two GMSK (GaussianMinimum Shift-frequency Keying, Gaussian Minimum Shift Keying) signal is generated based QPSK (Quadrature PhaseShift Keying, Quadrature Phase Shift Keying) signal , the MS technique by eliminating interference and enhanced training sequence orthogonal to each other, not their own signals, as to eliminate interference signals, thereby solving one signal of their own. 在上行方向,两个复用的MS使用GMSK调制在同一时隙发送信号,BTS使用SIC(Successive InterferenceCancellation,连续干扰消除)或者JD(Joint Detection, 联合检测)的方式解调两路复用的信号,并通过不同的训练序列来区别两个用户。 In the upstream direction, two multiplexed MS uses GMSK modulation signal is transmitted in the same time slot, the BTS using SIC (Successive InterferenceCancellation, successive interference cancellation) or JD (Joint Detection, joint detection) manner demodulated signal multiplexed in two and to distinguish between two users through the different training sequences.

[0004] 为了提高频谱效率、更有效地利用硬件和频谱资源,通常采用功率控制算法、按照一定的原则对MS的发射功率(即上行功率)进行控制。 [0004] In order to improve spectral efficiency, more efficient use of hardware and spectrum resource, usually a power control algorithm, the MS transmit power (i.e., uplink power) is controlled in accordance with certain principles. 该原则具体如下:如果BTS的接收电平或接收质量高于期望值,则适当降低MS的发射功率;如果BTS的接收电平或接收质量低于期望值,则适当提高MS的发射功率;同时综合考虑接收电平和接收质量因素,以提高功率控制的准确性和有效性。 The principle as follows: If the reception level or the reception quality of the BTS is higher than desired, it is appropriate to reduce the transmit power of the MS; If the level or quality of reception of the receiving BTS lower than expected, then a suitable increase the transmission power of the MS; while considering reception level and reception quality factors, in order to improve the accuracy and effectiveness of power control. 对MS的发射功率进行控制的过程如下:BSC(BaSe Station Controller,基站控制器)接收到BTS发来的一定数量的上行测量报告后,通过插值、滤波等处理方法得到实际上行链路的接收电平和接收质量,并与期望的上行链路的接收电平和接收质量相比较,根据比较的结果确定是否需要调整MS的发射功率,如果是,则通过功率控制算法,计算出应调整至的功率级别,向MS发送功率调整命令。 Process for controlling the transmission power of the MS as follows: BSC (BaSe Station Controller, Base Station Controller) sent to the BTS receives a number of uplink measurement report, the actual uplink reception level obtained by the processing method of interpolation and filtering level and reception quality, and compared with a desired power level and the reception quality of the reception of the uplink, determines whether to adjust the transmit power of the MS, if so, by the power control algorithm to calculate a power level should be adjusted according to the result of the comparison transmission power adjustment commands to the MS. 例如,分别设定接收电平的上限阈值和下限阈值以及接收质量的上限阈值和下限阈值,并设定计数器P和N。 For example, the reception level are set an upper threshold and a lower threshold and an upper threshold value of the reception quality and a lower threshold, and sets the counter P and N. 当连续接收P个测量报告中有N个超过上述阈值,则进行功率调整,如果是高于上限阈值则下调功率,如果是低于下限阈值则上调功率。 When P continuously received measurement reports that there are N exceeds the threshold value, the power adjustment is performed, if it is above the upper threshold power is lowered, if it is below the lower threshold power up.

[0005] 在对现有技术进行分析后,发明人发现:对复用的终端用户分别单独进行功率控制,可能会导致复用的信号之间干扰过大,接收和解调性能下降,甚至无法解调。 [0005] After the analysis of the prior art, the inventors found that: the end user are multiplexed power control alone, may result in interference between the multiplexed signals is too large, received and demodulated performance degradation, can not even demodulation.

[0028] 401 =BSC预设信号强度上限、信号强度下限、信号质量上限、信号质量下限、信号强度差值上限和信号强度差值下限,BSC接收来自BTS的测量报告,该测量报告中包括来自于复用MS的信号的强度和质量等信息,具体可以包括:BTS接收MSl的第一信号的强度Al 和质量Bl与BTS接收的MS2的第二信号的强度A2和质量B2。 [0028] 401 = BSC signal strength of the preset limit, the lower limit of the signal strength, signal quality limit, the lower limit of signal quality, signal strength difference between the upper limit and the lower limit of the difference between the signal strength, the BSC receives measurement reports from the BTS, from the measurement report comprises A2 and B2 strength strength mass Al and Bl quality received signal with a first BTS BTS MSl the received second signal MS2: to a multiplexed signal strength and quality of the MS information may include specific.

[0029] 其中,上限值可以根据需要设置为不同的值。 [0029] where, the upper limit value may be a different value as required. 例如,根据仿真结果设置信号强度下限和上限为(_60dbm,-80dbm),信号质量下限和上限为(0等级、2等级),信号强度差值下限和上限为(5dB,10dB)等等,其中信号质量的一个等级可以根据需要设置为不同的值,如4dB 等。 For example, according to the simulation result is set as the lower and upper signal strength (_60dbm, -80dbm), lower and upper limits signal quality (level 0, level 2), signal strength difference between lower and upper limits (5dB, 10dB) and the like, wherein a signal quality level at different values ​​may be provided as necessary, such as 4dB like.

[0030] 其中,接收信号的强度通常表现为接收电平值。 [0030] wherein the intensity of the received signal usually through the reception level value.

[0031] BSC在接收到测量报告后还可以进行预处理:进行插补以抵消丢失的部分测量报告的影响,进行滤波以抵消测量报告的偶然不稳定性的影响等等,从而保证测量报告的准确性和真实性,更好地进行功率控制。 [0031] BSC upon receiving the measurement report may also be pretreated: interpolated to offset the loss of a portion of a measurement report, filtered to offset the effects of accidental instability measurement report, etc., in order to ensure a measurement report accuracy and authenticity, better power control.

[0032] 402 :BSC判断Al是否在信号强度上限和信号强度下限之间,如果是,则不调整MSl 的发射功率;如果Al高于信号强度上限,则减小MSl的发射功率,如果Al低于信号强度下限,则增加MSl的发射功率;并且判断Bl是否在信号质量上限和信号质量下限之间,如果是,则不调整MSl的发射功率;如果Bl高于信号质量上限,则减小MSl的发射功率,如果Bl 低于信号质量下限,则增加MSl的发射功率。 [0032] 402: BSC Al determines whether the signal strength between the lower and upper signal strength, if it is, no adjustment of the transmission power MSl; Al, if the signal strength is higher than the upper limit, the transmission power is reduced MSl, if low Al signal strength lower limit, increasing the transmit power of MSl; Bl and determines whether the signal quality between the mass and the upper limit signal, if it is, no adjustment of the transmission power MSl; Bl if the signal quality is higher than the upper limit, is reduced MSl transmission power, if the signal quality is less than the lower limit Bl, then increasing the transmit power of MSl. 其中,根据信号强度和信号质量对MSl进行功率调整不分先后顺序,也可以同时进行,直到MSl的发射功率同时满足信号强度和信号质量的要求为止。 Wherein, based on the signal strength and signal quality of MSl power adjustment regardless of the order, it may be performed simultaneously, until the transmit power of MSl simultaneously meet the requirement of signal strength and signal quality.

[0033] 403 :BSC判断A2是否在信号强度上限和信号强度下限之间,如果是,则不调整MS2 的发射功率;如果A2高于信号强度上限,则减小MS2的发射功率,如果A2低于信号强度下限,则增加MS2的发射功率;并且判断B2是否在信号质量上限和信号质量下限之间,如果是,则不调整MS2的发射功率;如果B2高于信号质量上限,则减小MS2的发射功率,如果B2 低于信号质量下限,则增加MS2的发射功率。 [0033] 403: BSC A2 determines whether the signal strength between the lower and upper signal strength, if it is, no adjustment of the transmission power MS2; A2 if the signal strength is greater than the upper limit, the transmit power is reduced MS2, if low A2 signal strength lower limit, increasing the transmit power of MS2; B2 and determines whether or not the signal quality between the mass and the upper limit signal, if it is, no adjustment of the transmission power MS2; B2 if signal quality is higher than the upper limit, is reduced MS2 transmission power, if the signal quality is less than the lower limit B2, then increasing the transmit power of MS2. 其中,根据信号强度和信号质量对MS2进行功率调整不分先后顺序,也可以同时进行,直到MS2的发射功率同时满足信号强度和信号质量的要求为止。 Wherein, based on the signal strength and signal quality of the MS2 power adjustment regardless of the order, it may be performed simultaneously, until the transmit power of MS2 simultaneously meet the requirement of signal strength and signal quality.

[0034] 步骤402与403为BSC对MSl和MS2分别进行第一次功率调整,可以不分先后顺序,也可以同时执行。 [0034] Step 403 to 402 and the BSC MSl and MS2 respectively for the first power adjustment, regardless of the order may be, may be performed simultaneously.

[0035] 具体地,在增加发射功率时,可以将增加的功率值设置为:(信号强度上限+信号强度下限)/2-接收信号的强度;在减小发射功率时,可以将减小的功率值设置为:接收信号的强度_(信号强度上限+信号强度下限)/2。 [0035] Specifically, when increasing the transmission power, the power can be increased signal strength value is set to the upper limit + :( limit signal intensity) intensity / 2- signal is received; in reducing the transmission power, can be reduced to power value is set to: _ intensity (signal intensity upper limit + signal strength) of the received signal / 2.

[0036] 404 :BSC计算接收的来自两个移动台的信号强度的差值,假设Al >A2,则用二者相减得到差值A1-A2。 [0036] 404: difference signal strength from two mobile stations is received by the BSC, assuming Al> A2, the difference obtained by subtracting both the A1-A2.

[0037] 405 :根据计算得到的差值与上述差值范围,判断该差值A1-A2是否在预设的信号强度差值上限和信号强度差值下限之间,如果是,则BSC不对上述第一次调整后的两个MS的发射功率进行再次调整,流程可以结束;如果该差值A1-A2高于信号强度差值上限,则执行406 ;如果该差值A1-A2低于信号强度差值下限,则执行407。 [0037] 405: The difference between the calculated range difference described above, the difference A1-A2 determines whether a difference between a predetermined upper limit signal intensity difference between the signal strength and, if so, the BSC does not above MS, two after the first re-adjust the transmit power adjustment, the process may end; if the difference A1-A2 is higher than the upper limit signal intensity difference, 406 is performed; if the difference is lower than the signal strength A1-A2 the difference between the lower limit, perform 407.

[0038] 406 :按照减小上述差值的方向对第一次功率调整后的两个MS的发射功率进行调整,具体地,可以在满足Bl和B2均不小于信号质量下限的条件下,减小第一次调整后的MSl 的发射功率。 [0038] 406: follow the direction of decreasing the above two difference values ​​the transmission power of the MS after the first adjustment of power adjustment, in particular, can under Bl and B2 are not less than the lower limit signal quality is satisfied, Save MSl transmit power for the first time after a small adjustment.

[0039] 进一步地,减小MSl的发射功率后,还可以包括: After [0039] Further, MSl reduced transmit power may further comprise:

[0040] 如果Al达到信号强度下限且差值A1-A2仍高于信号强度差值上限,则增加第一次调整后的MS2的发射功率,直到差值A1-A2不高于信号强度差值上限或者A2达到信号强度上限或者B2达到信号质量上限,然后结束。 [0040] If the signal strength at the lower limit Al A1-A2 and the difference between the signal strength is still higher than the upper limit difference, MS2 transmit power is increased after the first adjustment, until the difference A1-A2 is not higher than the signal intensity difference A2 reaches the upper limit or the upper limit of the signal strength or signal quality reaches the upper limit B2, and then ends.

[0041] 407 :按照增加上述差值的方向对第一次调整后的两个MS的发射功率进行调整, 具体地,可以在满足Bl和B2均不小于信号质量下限的条件下,减小第一次调整后的MS2的发射功率。 [0041] 407: for increases in the direction of the above two difference values ​​the transmission power of the MS after the first adjustment to adjust, in particular, can under Bl and B2 are not less than the lower limit signal quality is satisfied, the first reduced MS2 transmit power after an adjustment.

[0042] 进一步地,减小MS2的发射功率后,还可以包括: [0042] Further, after reducing the transmission power of MS2, also comprising:

[0043] 如果A2达到信号强度下限且差值A1-A2仍低于信号强度差值下限,则增加第一次调整后的MSl的发射功率,直到差值A1-A2不低于信号强度差值下限或者Al达到信号强度上限或者Bl达到信号质量上限,然后结束。 [0043] If the signal strength at the lower limit A2 A1-A2 and the difference between the signal strength is still below the lower limit of the difference, the transmit power is increased MSl after the first adjustment, the difference A1-A2 until the signal strength is not less than the difference The lower limit of Al or Bl reaches the upper or signal strength quality signal reaches the upper limit and then ends.

[0044] 在本实施例中当计算得到的差值不满足预设的范围时,优先采用减小一个MS的发射功率的方式进行调整,其次再考虑增加另一个MS的发射功率的方式进行调整。 [0044] In the present embodiment, when the calculated difference does not satisfy the preset range, preferentially using a reduced transmit power mode of the MS is adjusted, then consider further increasing the transmit power is adjusted in a manner MS .

[0045] 在上述控制两个移动台的发射功率的过程中,包括第一次单独分别控制和第二次联合控制的过程,如果增加或减小的发射功率值超过预设的最大步长,则按照最大步长增加或减小发射功率;如果没有超过预设的最大步长,则按照实际计算的值增加或减小移动台的发射功率。 [0045] In the two control transmission power of the mobile station in the process, including the first and individually control the process of the second joint control, increased or decreased if the transmission power value exceeds the predetermined maximum step size, the increase or decrease transmission power according to the maximum step size; if not exceed the predetermined maximum step size, the increase or decrease transmit power of the mobile station according to the value actually calculated. 例如,预设的最大步长为2dB,如果需要增加或减小IdB时,则按照该值IdB 进行调整,如果需要增加或减小3dB,该值超过了最大步长,则按照最大步长2dB进行调整, 本次调整还未满足条件,则再次进行调整,每次调整的幅度均不能超过最大步长。 For example, the preset maximum length of 2dB step, if necessary to increase or decrease IdB is adjusted in accordance with the value IdB, if desired to increase or decrease 3dB, the value exceeds the maximum step size, the step size according to the maximum 2dB adjustment, this adjustment has not yet satisfied the conditions, then adjust again, the magnitude of each adjustment can not exceed the maximum step size. 另外,还可以分别设置按照信号强度进行功率调整时的最大步长,按照信号质量进行功率调整时的最大步长,以及按照信号强度差值进行功率调整时的最大步长,三种最大步长可以相同,也可以不同。 In addition, also provided are the maximum step size is adjusted according to the signal power strength, the maximum step size of the maximum step length power adjustment and power adjustment by the difference between the signal strength of the signal quality of the three maximum step size It may be the same or different.

[0046] 本实施例根据基站接收复用的移动台的信号强度的差值联合对复用的移动台进行功率控制,有效地抑制了复用的信号之间干扰过大的可能,提高了解调性能,改善了复用效果,使MUROS技术在提高语音容量的同时也保证了业务质量。 [0046] Example embodiment of the present joint multiplexed mobile station power control based on the difference of the receiving mobile station multiplexed signal strength of the base stations, effectively suppress interference between the multiplexed signals may be too large to improve demodulation performance, improved multiplexing effect, the MUROS technology to improve voice capacity while also ensuring the quality of service. 通过先单独对复用的移动台进行功率控制,然后再联合控制,可以进一步提高控制的准确性,极大地改善系统的性能。 The mobile station separately through the first multiplexed power control, and then the joint control, the control accuracy can be further improved, which greatly improve system performance. 在调整功率时优先考虑降低其中一个移动台的发射功率,在保证信号质量处于合理范围内时节省了MS的资源,对于降低MS的功耗,增加MS的待机时间等均有好处。 When adjusting the power priority decrease the transmit power of a mobile station, to ensure the signal quality in the MS saves resources within reasonable limits, to reduce the power consumption of the MS, the MS increases the standby time etc. is good.

[0047] 图4所示的方法中以BSC对两个MS的信号强度取差值进行相应的判断,这种方式还可以替换为其它方式,如计算比值的方式,下面具体举例说明。 The method shown in [0047] FIG. 4 to BSC signal strength taking the difference of two corresponding MS is determined, this approach may also be other alternative ways of computing the ratio, the following specific examples.

[0048] 参见图5,本发明实施例提供的移动台发射功率的控制方法,还可以具体包括: [0048] Referring to Figure 5, the mobile station transmission power control method according to an embodiment of the present invention, may further comprises:
