Abstract

Disclosed in the present invention are an uplink power control method and device. In embodiments of the present invention, a current actual state of an uplink is identified, and power control is performed according to the identification result. If a current actual state is an empty-packet state, empty packet processing is performed to reduce an uplink transmission power; furthermore, if real-time detection during the empty-packet state indicates occurrence of data and/or signaling transmission, the empty-packet state is changed to restore the uplink transmission power. In this way, the present invention reduces uplink system capacity consumption of empty uplink packets, and decreases a transmission power of a terminal, thus increasing the battery runtime of the terminal.

Description

一种上行链路功率控制方法及装置Uplink power control method and device 技术领域Technical field
本发明涉及UMTS移动通信***领域,特别涉及UMTS的HSUPA上行链路功率控制方法和装置。The present invention relates to the field of UMTS mobile communication systems, and in particular to a HSUPA uplink power control method and apparatus for UMTS.
背景技术Background technique
对于UMTS(Universal Mobile Telecommunication System,通用移动通信***)***,终端上行数据信道的发送通常伴随着上行控制信道的发送,而实际终端的上行数据信道平均占空比很低(占空比:数据发送在业务持续时间内的比例),这意味着上行控制信道在很多时候是不必要发送的,分析结果表明,因上行空包数据消耗的上行***容量超过上行***总量的50%,并导致终端的待机时间大大减少。For the UMTS (Universal Mobile Telecommunication System) system, the transmission of the uplink data channel of the terminal is usually accompanied by the transmission of the uplink control channel, and the average duty ratio of the uplink data channel of the actual terminal is low (duty cycle: data transmission) In the proportion of the duration of the service, this means that the uplink control channel is not necessarily sent in many cases. The analysis results show that the uplink system capacity consumed by the uplink null packet data exceeds 50% of the total uplink system and leads to the terminal. The standby time is greatly reduced.
随着数据业务的飞速增长,小区的空口容量问题日益突出。为了应对容量增大问题,调整DRBC FACH,PCH状态转换进行缓解。但终端在FACH,PCH态下进行Ping,Http等业务,性能不如在DCH态。如何保证业务的性能体验特别是ping包,http,即时聊天通信等,又不损失***容量,降低无数据发射时的功控信道的发射功率是比较经济务实的做法。同时,在保证终端要求的服务质量前提下,如何对处于空包的上行信道进行有效功率控制,最大程度降低终端的发射功率来减少上行干扰,从而增加***的上行容量和提升终端的待机时间,一直是UMTS***研究的关键问题。With the rapid growth of data services, the problem of air interface capacity of the community has become increasingly prominent. In order to cope with the capacity increase problem, the DRBC FACH is adjusted, and the PCH state transition is mitigated. However, the terminal performs services such as Ping and Http in the FACH and PCH modes, and the performance is not as good as in the DCH state. How to ensure the performance experience of the service, especially the ping package, http, instant chat communication, etc., without losing the system capacity, and reducing the transmission power of the power control channel without data transmission is a more economical and pragmatic approach. At the same time, under the premise of ensuring the quality of service required by the terminal, how to perform effective power control on the uplink channel in the null packet, thereby minimizing the transmission power of the terminal to reduce uplink interference, thereby increasing the uplink capacity of the system and improving the standby time of the terminal. It has always been a key issue in UMTS system research.

下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments.

本发明根据E-DPCCH的SIR来识别上行链路当前的实际状态,且当上行链路处于空包状态时,通过E-DPCCH的SIR来判断是否有数据发送,从而来控制发射功率,即若无数据发送,则降低终端上行的发射功率,从而提升***上行的容量,若有数据发送,即恢复或者提高终端上行的发射功率。The present invention identifies the current actual state of the uplink according to the SIR of the E-DPCCH, and determines whether there is data transmission through the SIR of the E-DPCCH when the uplink is in the empty packet state, thereby controlling the transmission power, that is, if If no data is sent, the uplink transmit power is reduced, thereby increasing the uplink capacity of the system. If data is transmitted, the uplink transmit power is restored or increased.
实施例一Embodiment 1
参见图1a,为本发明的一种上行链路功率控制方法的一实施例的流程图。本实施例中,该上行链路功率控制方法具体包括步骤:FIG. 1a is a flowchart of an embodiment of an uplink power control method according to the present invention. In this embodiment, the uplink power control method specifically includes the following steps:
S101,对上行链路的当前实际状态进行识别,若为空包状态,则执行步骤S103,否则,重新识别。S101: Identify the current actual status of the uplink, and if it is in the empty packet state, execute step S103, otherwise, re-recognize.
由于现有技术中,终端上行数据信道的发送通常伴随着上行控制信道的发送,并且上行数据信道平均占空比(占空比:数据发送在业务持续时间内的比例)很低,即在业务持续时间M个TTI内,无论是否有数据发送,该上行链路的状态处于非空包状态的,即SirTarget_DPCCH=SirTarget_RNC,这必然使得上行空包数据消耗的上行***容量超过上行***总量的50%。然而,在数据发送前或发送后,该上行链路其实是没有数据发送的,即其实际状态是处于空包状态。因此,为了实现上行链路功率控制,需要先对该上行链路的当前实际状态进行识别,若为空包状态,则进行空包处理,以降低上行的发射功率。具体地,该步骤S101包括步骤:In the prior art, the transmission of the uplink data channel of the terminal is usually accompanied by the transmission of the uplink control channel, and the average duty ratio of the uplink data channel (duty ratio: the ratio of data transmission in the duration of the service) is low, that is, in the service. Within the M TTIs of duration, regardless of whether there is data transmission, the state of the uplink is in a non-empty packet state, that is, SirTarget_DPCCH=SirTarget_RNC, which inevitably makes the uplink system capacity of the uplink null packet data exceed the total amount of the uplink system 50. %. However, before or after the data is transmitted, the uplink actually has no data to be sent, that is, its actual state is in an empty packet state. Therefore, in order to implement uplink power control, it is necessary to first identify the current actual state of the uplink, and if it is in the empty packet state, perform null packet processing to reduce the uplink transmit power. Specifically, the step S101 includes the following steps:
按照预设的间隔,连续获取N(1<N<M,该N为自定义的间隔)个TTI内的E-DPCCH的SIR,并判断是否每个TTI内的E-DPCCH的SIR均超过了预设的信干比门限值,若均未超过,则可知当前实际上是无数据发送,即该上行链路的当前实际状态为空包状态,执行步骤S103;否则,说明有数据发送,则该上行链路的当前实际状态为非空包状态,则不更改该上行链路的当前实际状态,并再次重新进行检测。According to the preset interval, consecutively obtain N (1 < N < M, the N is a custom interval) SIR of the E-DPCCH within the TTI, and determine whether the SIR of the E-DPCCH in each TTI exceeds If the preset signal-to-interference ratio threshold is not exceeded, it may be known that there is no data transmission at present, that is, the current actual state of the uplink is a null packet state, and step S103 is performed; otherwise, data transmission is performed. If the current actual state of the uplink is a non-empty packet state, the current actual state of the uplink is not changed, and the detection is performed again.
S103,进行空包处理,以降低终端上行的发射功率,执行步骤S105。S103: Perform null packet processing to reduce the uplink transmit power of the terminal, and perform step S105.
在一具体实施例中,当信令承载在E-DPDCH上时,通过将SirTarget_DPCCH降低DeltaSir_DPCCH以完成空包处理,从而降低终端上行的发射功率。 In a specific embodiment, when the signaling is carried on the E-DPDCH, the null packet processing is performed by lowering the SirTarget_DPCCH to complete the null packet processing, thereby reducing the uplink transmit power of the terminal.
在另一具体实施例中,参见图1b,当信令承载在DPDCH上时,在执行步骤S103之前,即将SirTarget_DPCCH降低DeltaSir_DPCCH之前,还需要对步骤S101的识别结果进行验证,即判断DPDCH信道上是否有信令发送,具体地,连续获取上述N个TTI中每个TTI帧尾检测DPCCH的TFCI字段,并判断是否每个TTI帧尾检测DPCCH的TFCI字段为0,若均为0,则确定上述识别结果正确,即上行链路的当前状态确实为空包状态,即既无数据发送,也无信令发送,则执行步骤S103,否则,执行步骤S101,即重新识别,并验证识别结果,直至验证识别结果正确时,也即是说需要重新连续获取N个TTI内E-DPCCH的SIR以及每个TTI帧尾检测DPCCH的TFCI字段,并进行判断,如此循环直至判断出每个TTI内E-DPCCH的SIR低于预设门限值,且每个TTI帧尾检测DPCCH的TFCI字段均为0为止,再进行空包处理。In another embodiment, referring to FIG. 1b, when the signaling is carried on the DPDCH, before the step S103 is performed, before the SirTarget_DPCCH is lowered by the DeltaSir_DPCCH, the identification result of the step S101 needs to be verified, that is, whether the DPDCH channel is determined. There is signaling, specifically, continuously acquiring the TFCI field of each TTI frame detection DPCCH in the foregoing N TTIs, and determining whether the TFCI field of the DPCCH is 0 in each TTI frame tail, and if all are 0, determining the above The recognition result is correct, that is, the current state of the uplink is indeed a null packet state, that is, neither data transmission nor signaling is sent, then step S103 is performed; otherwise, step S101 is performed, that is, re-identification is performed, and the recognition result is verified until When the verification result is correct, that is, it is said that the SIR of the E-DPCCH in the N TTIs and the TFCI field of the DPCCH of each TTI frame are required to be continuously obtained, and the judgment is performed, and the loop is determined until the E- in each TTI is determined. The SIR of the DPCCH is lower than the preset threshold, and the TFCI field of the DPCCH for each TTI frame detection is 0, and then the null packet processing is performed.
S105,实时检测经过空包处理的上述上行链路是否有数据和/或信令要发送,若是,则执行步骤S107,否则重新检测。S105: Real-time detection is performed on the uplink that is processed by the null packet, and whether data and/or signaling is to be sent. If yes, step S107 is performed, otherwise, re-detection is performed.
具体实施时,由于该上行链路进行了空包处理,即其当前的实际状态为空包状态,因此,可通过实时获取当前TTI内E-DPCCH的SIR,并判断所获取的SIR是否超过预设的信干比门限值来判断该上行链路是否有数据发送,若是,则判定为有数据发送,并执行步骤S107,否则为无数据发送,并执行步骤S105,即重新检测直至检测到有数据发送为止;和/或者,通过实时获取当前TTI帧尾检测DPCCH的TFCI字段,并判断该TFCI字段是否为0来判断上行链路是否有信令发送,若不为0,说明有信令发送,则执行步骤S107,否则,无信令发送,则重新检测,即执行步骤S105。In the specific implementation, since the uplink is subjected to the null packet processing, that is, the current actual state is a null packet state, the SIR of the E-DPCCH in the current TTI can be obtained in real time, and it is determined whether the acquired SIR exceeds the pre-predetermined state. The signal-to-interference ratio threshold is used to determine whether the uplink has data transmission. If yes, it is determined that there is data transmission, and step S107 is performed, otherwise, no data is transmitted, and step S105 is performed, that is, re-detection until detection. If there is data transmission; and/or, the TFCI field of the DPCCH is detected by the current TTI frame tail in real time, and it is determined whether the TFCI field is 0 to determine whether the uplink has signaling. If not, it indicates that there is signaling. If yes, go to step S107. Otherwise, if there is no signaling, re-detect, that is, step S105 is performed.
在一具体实施例中,对于信令承载在E-DPDCH上的情况,可通过实时获取当前TTI内E-DPCCH的SIR,并判断所获取的SIR是否超过预设的信干比门限值来判断该上行链路是否有数据发送,若是,则判定为有数据发送,并执行步骤S107,否则为无数据发送,并执行步骤S105,即重新检测直至检测到有数据发送为止;In a specific embodiment, for the case where the signaling is carried on the E-DPDCH, the SIR of the E-DPCCH in the current TTI can be obtained in real time, and it is determined whether the acquired SIR exceeds a preset signal-to-interference ratio threshold. Determining whether the uplink has data transmission, and if so, determining that there is data transmission, and executing step S107, otherwise, no data transmission, and performing step S105, that is, re-detecting until data transmission is detected;
在另一具体实施例中,对于信令承载在DPDCH上的情况,由于信令承载于DPDCH,因此,需要结合上述检测数据发送和检测信令发送的方式来进行检测,参见图1b,具体地,先判断是否有数据发送(即判断当前TTI内E-DPCCH的SIR是否超过预设的门限值),若判断出有数据发送,则可直接执行步骤S107,若判断出无数据发送时,则进一步判断是否有信令发送(即判断当前TTI帧尾检测DPCCH的TFCI字段是否为0),若判断出有信令发送,则执行步骤S107,否则,重新检测(实时检测是否有数据和/或信令发送);或者,也可以先判断是否有信令发送,若判断出有信令发送,则执行步骤S107,否则,再判断是否有数据发送,若判断出有数据发送,则执行步骤S107,否则,重新检测。也即是说,针对于信令承载在DPDCH上的情况,只需要检测出有数据发送或者有信令发送这两种情况中的任何一种,即需要解除该上行链路的空包状态,而具体是先判断有数据发送,还是先判断有信令发送,可以根据实际需要进行调整。 In another specific embodiment, for the case where the signaling is carried on the DPDCH, since the signaling is carried on the DPDCH, it is required to perform detection in combination with the foregoing detection data transmission and detection signaling transmission, see FIG. 1b, specifically First, it is determined whether there is data transmission (that is, whether the SIR of the E-DPCCH in the current TTI exceeds a preset threshold value). If it is determined that there is data transmission, step S107 may be directly performed, and if it is determined that no data is transmitted, Then, it is further determined whether there is signaling (ie, determining whether the TFCI field of the current TTI frame detection DPCCH is 0), and if it is determined that there is signaling, step S107 is performed, otherwise, re-detection (real-time detection of data and/or Or signaling (), or you can first determine whether there is signaling. If it is determined that there is signaling, proceed to step S107. Otherwise, determine whether there is data transmission. If it is determined that there is data transmission, perform steps. S107, otherwise, re-detect. That is to say, in the case that the signaling is carried on the DPDCH, only one of the two cases of data transmission or signaling needs to be detected, that is, the state of the empty packet of the uplink needs to be cancelled. Specifically, it is first determined whether there is data transmission, or it is first determined that there is signaling, which can be adjusted according to actual needs.
进一步地,由于是根据所获取的SIR来检测是否有数据发送,但有可能存在虚检的情况,因此,参见图1b,当判断出所获取的SIR超过预设的门限值后,执行步骤S107之前,还需要校验是否存在虚检的情况,若不存在,再执行步骤S107,具体地,可通过判断当前TTI内E-DPCCH的RSN字段是否为0,若是,则不为虚检,执行步骤S107,否则为虚检,并重新检测。Further, since it is detected whether there is data transmission according to the acquired SIR, there may be a case of a virtual check. Therefore, referring to FIG. 1b, when it is determined that the acquired SIR exceeds a preset threshold, step S107 is performed. Before that, it is also required to check whether there is a virtual check. If not, step S107 is performed. Specifically, it can be determined whether the RSN field of the E-DPCCH in the current TTI is 0. If yes, the virtual check is not performed. Step S107, otherwise it is a false check and is re-detected.
S107,解除空包状态。具体实施时,通过设置当前SirTarget_DPCCH=SirTarget_RNC,以解除空包状态。S107, the empty packet status is released. In the specific implementation, the current packet state is cancelled by setting the current SirTarget_DPCCH=SirTarget_RNC.
本实施例中通过对上行链路当前的实际状态进行识别,并根据识别结果来进行功率控制,即当其当前实际状态为空包状态时,则进行空包处理以降低重大的上行发射功率,而当其在空包状态下,要数据发送时,则解除其空包状态,以恢复其上行发射功率,从而降低上行空包数据消耗的上行***容量,节省终端发射功率,进而提升终端的待机时间。In this embodiment, the current actual state of the uplink is identified, and power control is performed according to the identification result, that is, when the current actual state is the empty packet state, the null packet processing is performed to reduce the significant uplink transmit power. When it is in the empty packet state, when data transmission is required, the empty packet state is released to restore its uplink transmission power, thereby reducing the uplink system capacity of the uplink null packet data consumption, saving terminal transmission power, thereby improving terminal standby. time.
