Description

蜂窝系统、基站及移动台、以及通信控制方法 Cellular system, a base station and a mobile station, and a communication control method

[0001] 本申请是基于申请号为03807558.X,申请日为2003年4月3日,题为“蜂窝系统、基站及移动台、以及通信控制方法”的发明提出的分案申请。 [0001] This application is a divisional application filed on Application No. 03807558.X, filed April 3, 2003, entitled "cellular system, a base station and a mobile station, and a communication control method" of the present invention.

技术领域 FIELD

[0002] 本发明涉及蜂窝系统、基站及移动台、以及通信控制方法。 [0002] The present invention relates to a cellular system, a base station and a mobile station, and a communication control method.

背景技术 Background technique

[0003] 以往,对于这种蜂窝系统提出有各种系统。 [0003] Conventionally, for such cellular systems have been proposed various systems. 最近,作为这种蜂窝系统之一,由3GPP (第三代伙伴项目)提出了高速下行分组接入(HSDPA:High-Speed Downlink PacketAccess)方式的蜂窝系统。 Recently, as one of such a cellular system, the 3GPP (Third Generation Partnership Project) proposed high-speed downlink packet access (HSDPA: High-Speed ​​Downlink PacketAccess) mode cellular system.

[0004] 下面,对于进行分组通信的蜂窝系统,以上述HSDPA方式的蜂窝系统为例进行说明,但本发明并不局限于HSDPA。 [0004] Next, for a cellular packet communication system, a cellular system according to the HSDPA system will be described as an example, but the present invention is not limited to HSDPA.

[0005] 在HSDPA方式中,将高速数据传送到从蜂窝系统的基站向移动台的下行链路,进而,为进行从基站向移动台的下行链路的传送而使用了高速下行共享信道(HS-PDSCH:High-Speed Physical Downlink SharedChannel)。 [0005] In HSDPA, the high-speed data transfer to the downlink from the base station to the mobile cellular system, and further, to perform downlink transmission to the mobile station using a high speed downlink shared channel (HS from the base station -PDSCH: High-Speed ​​Physical Downlink SharedChannel). 该HS-PDSCH 是用于从各基站向多个移动台进行数据发送的,因此,基站及其控制站确定向多个移动台中的各台进行数据发送的时间表,按每个移动台以不同的时刻(时分方式)发送数据。 The HS-PDSCH is used for data transmission from each base station to a plurality of mobile stations, the base station determines that the mobile station and to a plurality of stations each station schedules for transmission of data, each mobile station in different time (time-division manner) to send data.

[0006] 为控制从所述基站向移动台的数据发送,各基站在与多个移动台的各台之间设定了专用信道DPCH(专用物理信道)。 [0006] transmits data to the mobile station from the base station to control, and the plurality of base stations between the mobile stations in each station set up a dedicated channel DPCH (Dedicated Physical Channel). 该DPCH被用于通过该下行链路信号从基站向移动台发送控制信息,同时通过上行链路信号从移动台向基站发送控制信号。 The DPCH is used to send control information from the base station to the mobile station by the downlink signal to the base station simultaneously transmits a control signal from the mobile station via an uplink signal.

[0007] 在各移动台中,利用HS-PDSCH发送数据的时间比例小,但即使在不发送数据的数据等待状态下,与基站之间还继续设定DPCH,当请求发送数据时,就可以在短时间内开始数据发送。 [0007] In each mobile station, using the HS-PDSCH small percentage of time sending data, but the data is not even in the waiting state for transmitting data between the base station and the DPCH continues to be set, when a request to transmit data, it may be a short time to start data transmission. 因此,各基站同时进行数据发送的移动台在同一时刻只有一个,多数移动台处于数据等待状态,并在与基站之间设定DPCH。 Thus, each base station while the mobile station transmits data to only one, the majority of the mobile station is in a data wait state at the same time, and set the DPCH between the base station.

[0008] 此外,在蜂窝系统中具有称为软交接的技术,可使得移动台与多个基站同时设定信道。 [0008] Further, in a cellular system having a technology referred to as soft handover, the mobile station may be such that a plurality of base stations simultaneously with a channel set. 各基站以规定功率发送公共导频信号,移动台与公共导频信号的发送功率最大的基站设定DPCH,但在软交接中,当存在公共导频信号的发送功率的差很小的其他基站时,也与其他基站设定DPCH,从而与多个基站设定DPCH。 Each base station transmits at a predetermined power of the common pilot signal transmission power of the base station of the maximum signal, the mobile station to set the DPCH and common pilot, but in the soft handover, the other base stations when the difference between the transmission power of a common pilot signal is present in very small when, DPCH be set with other base stations, so that the plurality of base station sets the DPCH. 在下面的说明中,将这样在软交接中设定DPCH的基站称为连接基站。 In the following description, it referred to thus set the DPCH base station in soft handover the connection.

[0009] 另外,在蜂窝系统中应用了称为快速闭环发送功率控制的技术。 [0009] Further, the application technique called fast closed-loop transmission power control in a cellular system. 该快速闭环发送功率控制对于DPCH适用于其上行链路与下行链路二者。 The fast closed loop transmission power control for both the uplink DPCH and suitable for its downlink. 在DPCH的上行链路的发送功率控制中,基站使用被包含在上行信号中的专用导频信号来测量其接收SIR(信号干扰比),并将该测量值与预定的目标SIR作比较。 In the transmission power control of the uplink DPCH, the base station uses a dedicated pilot signal is included in the uplink pilot signal to measure the receiving SIR (Signal to Interference Ratio), and the measured value with a predetermined target SIR for comparison. 然后,当该测量值比目标SIR小时,将表示功率增加的TPC(传输功率控制)比特包含在DPCH的下行信号中通知给移动台;除此之外的时候将表示功率减少的TPC比特包含在DPCH的下行信号中通知给移动台。 Then, when the measured value than the target SIR hours, indicating a power increase TPC (Transmit Power Control) bits contained in the DPCH of the downlink signal to the mobile station; In addition, when the TPC bit indicates reduction of power contained in the DPCH downlink signal to the mobile station. 然后,移动台接收该TPC比特,并根据该TPC比特来增减发送功率。 Then, the mobile station receives the TPC bits, and decreases the transmission power based on the TPC bit. [0010] 当在软交接的同时利用上行链路的发送功率控制时,移动台从多个连接基站的各站接收TPC比特,当至少一个TPC比特表示功率减少时,使DPCH的发送功率减少,除此之外的时候(即,所有TPC比特都表示功率增加时),使DPCH的发送功率增加。 [0010] When the soft handover while using an uplink transmission power control, the mobile station receives TPC bits from a plurality of connection base stations, and when at least one TPC bit indicates reduction of power when the transmission power of the DPCH is decreased, in addition, when (i.e., when all the TPC bits are represented by an increase in power), the transmission power of the DPCH is increased. 通过进行这种发送功率控制,在至少一个连接基站中,在上行链路信号的接收质量满足目标SIR的同时,在所有连接基站中,都能够防止上行链路信号的接收质量超过目标SIR,使得上行链路的干涉波功率不增加。 By performing such transmission power control, at least one connection base station, the uplink signal reception quality satisfies the target SIR at the same time, all connected base stations are capable of preventing the reception quality of the uplink signal exceeds the target SIR, so that interference wave power of the uplink is not increased.

[0011] 另一方面,在DPCH的下行链路的发送功率控制中,移动台利用包含在下行信号中的专用导频信号来测量该接收SIR,并将该测量值与预定的目标SIR相比较。 [0011] On the other hand, the transmission power control of the downlink DPCH, the mobile station contained in the downlink signal using the dedicated pilot signals to measure the reception SIR, and the measured value is compared with a predetermined target SIR . 然后,当该测量值小于目标SIR时,将表示功率增加的TPC比特包含在DPCH的上行信号中通知给基站;除此之外的时候将表示功率减少的TPC比特包含在DPCH的上行信号中通知给基站。 Then, when the measured value is less than the SIR target, representing the TPC bit to increase the power to the base station comprises notification of an uplink DPCH signal; except when the TPC bit indicates reduction of power contained in the notification of the uplink DPCH signal to the base station. 然后,基站接收该TPC比特,并根据该TPC比特来增减发送功率。 Then, the base station receives the TPC bit, and decreases the transmission power based on the TPC bit.

[0012] 当在软交接的同时利用下行链路的发送功率控制时,移动台从多个连接基站的各站接收DPCH的下行链路信号并将其合成,将合成后的下行链路信号的接收SIR与目标SIR相比较来确定TPC比特。 [0012] When the soft handover, while a downlink transmission power control, the mobile station receives the downlink signal of the DPCH from each of plurality of connection base stations and the synthesis, the synthesized downlink signal received SIR and the target SIR determined by comparing the TPC bit. 然后,向多个连接基站发送共同的TPC比特,连接基站的各站根据该TPC比特来增减发送功率。 Then, a plurality of connection base stations sends a common TPC bits, each station connected to the base station decreases the transmission power based on the TPC bit. 如此,通过所有连接基站根据共同的TPC比特来增减发送功率,能够保持连接基站之间的发送功率的均衡,使得在移动台之间的传输损失最小的连接基站所发送的下行链路信号能够被移动台以良好的质量接收,从而能够防止下行链路信号的发送功率增加到所需以上,使得下行链路的干涉波功率不增加。 Thus, all the connected base station decreases the transmission power by the TPC bit in accordance with a common, balanced transmission can be connected between the power station, so that the downlink signal transmission loss between the mobile station connected to the base station transmitted the smallest possible by the mobile station with good reception quality, thereby preventing the transmission power of a downlink signal is increased more than necessary, so that the interference wave power of the downlink is not increased.

[0013] 以上说明的发送功率控制与软交接作为无线接入方式,特别是在CDMA(码分多址)方式的蜂窝系统中,对于通过降低发送功率来降低干涉波功率从而使线路容量增加,是一种有效的技术。 [0013] transmission power control and soft handover described above, as radio access schemes, especially in a cellular system, CDMA (Code Division Multiple Access) scheme, by reducing the transmission power to reduce interference wave power to increase line capacity so that, It is an effective technique.

[0014] 这里,在软交接之中,如图10中对系统概略所示,上述已说明移动台(MS)3是与多个连接基站(BS) 1、2同时连接DPCH的,但HS-PDSCH只与一个基站(在图中为基站I)相连。 [0014] Here, in the soft handover, as shown in the schematic system shown in FIG. 10 pairs, the mobile station has been described above (MS) 3 is connected to a plurality of base stations (BS) 1,2 DPCH simultaneous connections, but HS- PDSCH is connected to only one base station (the base station in FIG. I). 此外,如上所述,移动台3需要将表示是否无差错地接收了由该HS-PDSCH发送过来的分组包的收到确认通知(ACK/NACK:确认/不确认)信息向基站发送,该收到确认通知信息是使用上行链路的HS-DPCCH(高速专用物理控制信道:包括分组的发送控制信息的HS-PDSCH专用控制信道)来发送的。 As described above, the mobile station needs to be 3 indicating whether the packet is received without error by the packet transmitted over the HS-PDSCH receive a confirmation notification (ACK / NACK: acknowledgment / not acknowledgment) message to the base station, the folding the confirmation information using an uplink HS-DPCCH (High Speed ​​dedicated physical control channel: a dedicated control channel HS-PDSCH for transmitting control information packet) is transmitted.

[0015] 该上行链路的HS-DPCCH与上行链路的DPCH之间的关系如图11所示,DPCH由DPCCH(专用物理控制信道)与DPDCH(专用物理数据信道)构成,DPCCH包括专用导频信道(Pilot)、TPC比特和FBI (反馈信息)。 [0015] The relationship between the DPCH HS-DPCCH uplink the uplink 11, DPCH consists of DPCCH (Dedicated Physical Control Channel) and DPDCH (Dedicated Physical Data Channel), the DPCCH comprises a dedicated pilot pilot channel (pilot), TPC bits and the FBI (feedback information). 此外,DroCH为数据(Data),包含用户信息和控制信息。 Further, DroCH data (Data), comprising the user information and control information. 该DPCCH与DroCH被相互正交调制并多路化之后被发送出去。 The DPCCH and DroCH after being mutually orthogonal modulation and multiplexing are transmitted.

[0016] HS-DPCCH被分成相当于DPCCH或DTOCH三倍时隙的时隙长度,并且先前说明的收到确认通知(ACK/NACK)信息及表示下行链路质量的CQI (信道品质指示)被包含在内。 [0016] HS-DPCCH slot is divided into a length corresponding to triple DPCCH slots or DTOCH, and receive a confirmation notification (ACK / NACK) information, and indicates the quality of the downlink CQI (Channel Quality Indication) is the previously described It included. 该HS-DPCCH与DPCH以码分多路被发送。 The DPCH and the HS-DPCCH to be transmitted code division multiplexed. 另外,对包含于该HS-DPCCH中的ACK(接收)/NACK(否)信号的判断,只在发送HS-PDSCH的基站,即分组包发送基站内进行,故不进行基站之间的分集合成。 Further, the ACK included in the HS-DPCCH in the (received) / NACK (NO) determination signal, only the base station transmits the HS-PDSCH, i.e. packets packet in the transmission base station, it does not perform diversity synthesis between the base station .

[0017] 另一方面,如图10所示,上行链路的DPCH在无线网络控制站(RNC)IO中,进行连接基站1、2之间的分集合成,同时,该DPCH如上所述,通过快速闭环发送功率控制将其控制为预定的发送质量,且HS-DPCCH的发送功率PH是以在该DPCH的发送功率H)上加上预定的偏移功率Λ而得到的功率发送的。 [0017] On the other hand, as shown, the uplink DPCH in the radio network controller (RNC) IO, the diversity combining for 10 connected between the base stations 1 and 2, while the DPCH as described above, fast closed loop transmission power control which is controlled to a predetermined transmission quality, and the HS-DPCCH transmission power PH is the power Λ adding a predetermined offset in the transmission power of the DPCH H) obtained in the power transmission. 即,以如下关系发送: That is, the transmission to the following relationship:

[0018] PH = PD+Λ (I)。 [0018] PH = PD + Λ (I).

[0019] 如此,利用HS-PDCCH,基于从移动台发送的ACK/NACK,分组发送基站判断是否在移动台正确地接收到了分组包,如判断为NACK,则认为与其相应的分组包在移动台没有被正确地接收到,再次进行该分组包的发送,以防止分组包丢失。 [0019] Thus, using the HS-PDCCH, based on ACK / NACK transmission from a mobile station, the packet transmission base station determines whether the mobile station correctly receives the packet the packet, if the judgment is NACK, the considered its corresponding packet packet at the mobile station It is not received correctly, the packet transmission packets again, in order to prevent packet loss.

[0020] 这里,特别是当把NACK误判定为ACK时,即使分组包没有被正确地接收,该基站也会发送下一个分组包,因而,那个没有被正确接收的分组包就不会被再发送,而是在移动台丢失了,从而发生分组包丢失。 [0020] Here, in particular when the erroneously determined NACK is ACK, even if a packet is not correctly received packet, the base station also sends a packet packet, therefore, that the packet is not correctly received packet will not be re- transmitting, at the mobile station but lost to packet loss occurs. 因此,对于NACK的接收差错率必须要比对于ACK的接收错误率小得足够多,换句话说,需要充分提高在分组包发送基站的ACK/NACK信号的接收质量。 Thus, for the reception error rate than necessary for receiving the NACK error rate sufficiently ACK is much smaller, in other words, it is necessary to sufficiently increase the reception quality of the base station in a packet ACK packet transmitted / NACK signal.

[0021] 但是,如果不采取什么对策,由于如下所述的动作,ACK/NACK的接收质量会降低。 [0021] However, if any measures are not taken, due to the operation of the reception quality of ACK / NACK may be reduced.

[0022] 在软交接运行中,作为HS-DPCCH的发送功率基准的UL (Up-Link:上行链路)DPCH的发送功率被如下进行控制。 [0022] In soft handover operation, as a reference transmission power of the UL HS-DPCCH (Up-Link: Uplink) transmission power of the DPCH is controlled as follows. 当UL DPCH的接收SIR比基准SIR大时,连接基站发送使功率减少的TPC信号,而当合成后的接收SIR比基准SIR小时,其发送使功率增加的TPC信号。 When receiving SIR UL DPCH is greater than the reference SIR, the base station connection of the power transmission to reduce a TPC signal, and when the reception SIR than the reference SIR after combining hours, so it sends a TPC power increase signal.

[0023] 此外,软交接运行中的移动台从各连接基站接收TPC信号,并在所有TPC信号都为功率增加时,使发送功率增加,在至少有一个TPC信号为功率减少时,使发送功率减少。 When [0023] In addition, the mobile station soft handover operation of the received TPC signals from the respective connection base station, and when all the TPC signals are increased as the power, the transmission power is increased, when at least one TPC signal power decrease, the transmission power cut back. 此时,虽然分组包发送基站的UL DPCH的接收SIR未达到基准SIR,但如果除此之外的基站的UL DPCH的接收SIR为基准SIR以上,则由于相对于移动台的至少一个TPC信号为功率减少,所以移动台使UL DPCH的发送功率减少,而分组包发送基站的UL DPCH的接收SIR会进一步降低。 In this case, although the reception SIR of the base station packet UL DPCH transmitted packets does not reach the reference SIR, but the reception SIR of the UL DPCH if the base station is other than the reference SIR or more, since at least one TPC signal with respect to the mobile station power reduction, the mobile station UL DPCH transmission power is reduced, and reception SIR of the base station packet UL DPCH transmitted packet is further reduced. 因此,HS-DPCCH的接收质量降低。 Thus, the reception quality of HS-DPCCH is reduced.

[0024] 如此,在软交接中,由于分组包发送基站以外的TPC信号,存在HS-DPCCH的接收质量降低,从而容易产生AC K/NACK的接收差错的问题。 [0024] Thus, in soft handover, the TPC signal transmitted packet since the packet than the base station, the reception quality of HS-DPCCH is present is reduced, so that the problem of reception errors easily generated AC K / NACK's.

[0025] 在软交接运行中,如下述那样控制含有TPC信号的DL (Down-Link:下行链路)DPCH的发送功率,其中,该TPC信号是用于控制UL DPCH的发送功率的。 [0025] In soft handover operation, controlled as follows DL (Down-Link: downlink) TPC signal containing the transmission power of the DPCH, which is the TPC signal for controlling the transmission power of the UL DPCH. 软交接运行中的移动台合成从各连接基站发送的DLDPCH,并在合成后的接收SIR比基准SIR大时,发送使功率减少的TPC信号,而在合成后的接收SIR比基准SIR小时,发送使功率增加的TPC信号,各基站根据该TPC信号来控制发送功率。 The mobile station synthetic soft handover operation from DLDPCH each connection base station, and when the received SIR after combining is larger than the reference SIR, the transmission of the power to reduce the TPC signal at the receiving SIR after combining than the reference SIR h, transmission so that a TPC power increase signal, each base station to control transmission power based on the TPC signal.

[0026] 此时,虽然分组包发送基站的DL DPCH的接收SIR比基准SIR小,但是如果除此之外的基站的DL DPCH的接收SIR大的话,则由于合成后的接收SIR比基准SIR大,各基站使DL DPCH的发送功率减少,分组包发送基站的DL DPCH的接收SIR进一步降低。 [0026] In this case, although the reception SIR of the base station transmits packet packet the DL DPCH SIR smaller than the reference, but if the DL DPCH reception SIR of the base station other than large, because the received SIR than the reference SIR after combining large each base station transmission power reduction the DL DPCH, the base station transmits the packet to further reduce the packet receiving the SIR of the DL DPCH. 因此,从分组包发送基站发送的TPC信号的接收质量降低,于是TPC信号的接收差错就会增加。 Thus, the reception quality of the packet transmitted from the packet transmission base station TPC signal decreases, the error thus received TPC signal is increased. 此时,由于分组包发送基站使UL DPCH的接收SIR增加,所以即使移动台发送使发送功率增加的TPC信号,也会由于该TPC信号的差错,而存在UL DPCH的接收SIR降低,与之相应地HS-DPCCH的接收质量降低,容易产生ACK/NACK的接收差错的问题。 At this time, since the base station transmits a packet so that the packet reception SIR UL DPCH is increased, even if the transmission power of the mobile station transmits TPC signal increase, also due to an error of the TPC signal, and there is a reception SIR UL DPCH decreases, corresponding thereto the reception quality of the HS-DPCCH is reduced, the problem of reception errors prone to the ACK / NACK.

[0027] 特别是,在各基站中,由于产生TPC信号的接收差错,分组包发送基站的DL DPCH的发送功率比其他基站的DL DPCH的发送功率小,从而上述问题变得容易产生。 [0027] In particular, in each base station, since the signal TPC reception error is generated, the packet transmission power of the DL DPCH transmitted packet is smaller than the base station transmission power of the DL DPCH other base stations, so that the above problem is liable to occur.

[0028] 用于改善以上问题的以往方式公知有以下两种方法。 Conventional manner [0028] For improving the above problems the following two methods are known.

[0029] 第一种方法是,移动台使HS-DPCCH的偏移功率Λ值在软交接状态时比在非软交接状态时有增加。 [0029] The first method, the mobile station that the offset value Λ HS-DPCCH power ratio of increase in the non-soft handover state when the soft handover state. 在该方法中,由于合适的△根据连接基站的数目、发送分组包的链路的UL接收质量等而不同,所以存在确定最优△的增量比较困难的问题。 In this method, since the UL reception quality △ suitable number of connected base stations, the transmission link for the packets is different, there is determined an optimal increment △ difficult problem. 此外,为了使ACK/NACK的接收差错率足够小,就需要使△值足够大,从而上行链路的发送功率大到所需以上,存在增加移动台的消耗功率,同时还增加上行链路的干涉波功率的缺点。 Further, in order that the reception error rate of ACK / NACK is small enough, it is necessary to make △ is large enough, so that uplink transmission power is large more than necessary, there is an increase in the consumption power of the mobile station, while also increasing the uplink disadvantage of the interference signal power.

[0030] 另外,由于HS-DPCCH的发送功率比DPCCH大,所以存在DPCCH的导频信号的接收质量降低,且信道推断精度降低的缺点。 The reception quality of a pilot signal [0030] Moreover, since the HS-DPCCH transmission power is larger than the DPCCH, the DPCCH there is reduced, and the channel estimation accuracy decreases the disadvantages. 为消除上述缺点,也考虑过向HS-DPCCH施加导频信号,但由于常发送只使用于软交接中的导频信号,存在降低资源的使用效率的问题。 To eliminate the above drawbacks, it is also contemplated applying a pilot signal to the HS-DPCCH, but since the normally used only in soft handover send the pilot signal, there is a problem of reducing the efficiency of use of resources.

[0031] 第二种方法是,软交接(SHO)中,分组包发送基站相对于HS-DPCCH的接收质量生成快速闭环控制式发送功率控制用的信号TPC-HS,以代替通常的TPC信号,或者将二者都向移动台发送。 [0031] The second method is a soft handover (the SHO), the base station transmits the packet with respect to a packet reception quality of HS-DPCCH generated fast closed-loop controlled transmission power control signal TPC-HS, instead of a normal TPC signal, or both to the mobile station. 在该方法中,为在分组包发送基站中满足ACK信号、NACK信号质量,必须使要求质量更严格地来设定目标SIR。 In this method, in order to meet the ACK signal packet in the packet transmitting station, NACK signal quality, quality requirements must be more strictly sets the target SIR. 因此,具有消耗过量的发送信号的缺点。 Thus, the transmission signal having the disadvantage of excessive consumption. 此外,当代替通常的TPC而发送TPC-HS时,HS-DPCCH的功率上升而产生干涉,其结果是,存在其他信道的DPCCH的信道推断精度降低的缺点。 Further, when the TPC-HS is transmitted instead of the usual TPC, HS-DPCCH power interference rise, as a result, the presence of other channels DPCCH channel estimation accuracy decreases the disadvantages. 另外,当发送与通常的TPC不同的TPC-HS时,需要改变时隙格式。 Further, when normal transmitting a TPC different TPC-HS, slot format needs to be changed.

[0032] 本发明的目的是提供一种蜂窝系统,该系统可解决上述现有问题,并可在基站内以高质量接收从移动台向基站发送的、用于分组包收到确认通知的ACK/NACK信号。 [0032] The object of the present invention is to provide a cellular system that can solve the above conventional problems, and high-quality transmission and reception from the mobile station to the base station within a base station, an ACK packet for confirmation of the received packet / NACK signal.

具体实施方式 Detailed ways

[0072] 下面参照附图,对本发明的第一至第五实施例进行说明。 [0072] Referring to the drawings, the first to fifth embodiments of the present invention will be described. 图1是本发明的第一至第五实施例都适用的蜂窝系统的一个例子的概括示意图。 FIG. 1 is a generalized schematic diagram of an example of the first to fifth embodiments of the present invention are applicable to a cellular system. 参照该图,蜂窝系统包括基站1,基站2,移动台3、4、5。 Referring to the figure, the cellular system including a base station 1, station 2, the mobile station 3,4,5. 而且,将基站I与基站2设置在不同的小区内。 Furthermore, base station I and station 2 is provided in different cells. 此外,在本例中,虽然是对相对于三个移动台3、4、5存在两个基站1、2的情形进行了说明,但是并不局限于此,同样也适用于相对于三个移动台3、4、5存在三个以上基站的情形。 Further, in this embodiment, although the case is with respect to the three mobile stations 3, 4 there are two base stations 1 and 2 has been described, but is not limited to this, the same applies to movement with respect to three 3,4,5 station there are cases where three or more base stations. 一般来说,相对于一个基站存在多个移动台。 In general, a base station with respect to a plurality of mobile stations exist.

[0073] 此外,本发明也适用于在该发送系统内存在四个以上移动台的情形,该图将存在三个移动台3、4、5的情形作为一个例子示出。 [0073] Further, the present invention is also applicable to the case where the mobile station memory in the transmission system, four or more, there will be the case in FIG three mobile stations 3, 4 is shown as an example.

[0074] 此外,作为基站与移动台3、4、5之间的无线接入方式,可采用CDMA(码分多址)方式。 [0074] Further, as a radio access scheme between a base station and a mobile station 3,4,5 can be CDMA (Code Division Multiple Access) mode.

[0075] 该图示出了从基站I向移动台3发送HS-PDSCH信号、DPCH I (DL =Down-Link:从基站向移动台的发送)信号和CPICH I (公共导频信号I)信号;从移动台3向基站I发送DPCH I (UL =Up-Link:从移动台向基站的发送)信号。 [0075] The figure shows the HS-PDSCH transmission signal from the base station to the mobile station 3 I, DPCH I (DL = Down-Link: sending from the base station to mobile station) signal and CPICH I (common pilot signal I) signal ; from the mobile station to the base station 3 transmits DPCH I I (UL = Up-Link: sending from the mobile station to the base station) signal. 此外,还示出了从移动台3向基站I发送如图11所示的HS-DPCCH (UL)信号。 In addition, also shows (UL) HS-DPCCH signal from the mobile station 11 shown in FIG 3 transmits to the base station I.

[0076] 同样,示出了从基站2向移动台3发送DPCH 2 (DL)信号和CPICH2信号;从移动台3向基站2发送DPCH 2 (UL)信号。 [0076] Similarly, shows a DPCH 2 (DL) signal and CPICH2 signals transmitted to the base station 2 from the mobile station 3; 3 transmits DPCH 2 (UL) signal from the mobile station to the base station 2. 该DPCH 2 (UL)虽然与DPCH I(UL)接收的基站不同,但作为移动台的发送信号,与DPCH I(UL)是相同的。 This DPCH 2 (UL) although DPCH I (UL) receiving different base stations, but the mobile station as a transmission signal, and DPCH I (UL) are the same. S卩,示出了HS-DPSCH信号及CPICH信号是单向信号,DPCH信号是双向信号。 S Jie, shows a HS-DPSCH signals are unidirectional signals and CPICH signals, the DPCH signal is a bidirectional signal.

[0077] HS-PDSCH为高速信道,用于以短时间收发动画等大型文件。 [0077] HS-PDSCH high-speed channel, a transceiver for a short time animation large files. 此外,CPICH为公共导频信道(只是DL),通过该信道从基站1、2向移动台3全时发送公共导频信号。 In addition, CPICH is a common pilot channel (only DL), 1,2 transmits a common pilot signal to the mobile station 3 wholly through the channel from the base station.

[0078] 此外,DPCH为专用(物理)信道(UL及DL),如图11所示,其是由DPCCH与DPDCH构成的。 [0078] Also, the DPCH is a dedicated (physical) channel (UL and the DL), shown in Figure 11, which is constituted by the DPCCH and DPDCH. 此外,如上所述,在HS-DPCCH中包括ACK/NACK信号和表示下行链路的传送路线质量的CQI等,这DPCCH与HS-DPCCH之间的发送功率的关系,如先前的公式(I)所示。 Further, as described above, including ACK / NACK signal and CQI represents the quality of the transmission path or the like in the downlink HS-DPCCH, the DPCCH that transmit power relation between the HS-DPCCH, as in the previous formula (I) Fig.

[0079] 接着,对第一至第五实施例所有共同的动作进行说明。 [0079] Next, an operation common to all the first to fifth embodiments will be described. 各基站1、2分别发送CPICH Each base station transmits CPICH 1 and 2, respectively

1、2,该CPICH按每个小区通过不同的扰频符号扩展,从而各移动台通过扰频符号的差异进行小区的识别。 2, the cell CPICH for each symbol by different scrambling extended to each mobile station identified by differential cell scrambling symbols. 各移动台在接收下行数据时,设定一个或多个基站与DPCH(UL/DL),变成数据等待状态。 Each mobile station when receiving downlink data, to set one or more base stations and DPCH (UL / DL), the data becomes a wait state.

[0080] 当基站1、2之间CPICH的接收功率的差为预定值以下时,一个移动台3不仅与基站I而且与基站2设定DPCH,成为与多个基站1、2设定DPCH的状态(软交接)。 [0080] When the difference is below a predetermined value between the CPICH reception power of a base station 1, only one mobile station 3 and base station 2 is set to I and DPCH with the base station, and a plurality of base stations become DPCH 1 is set state (soft handover).

[0081] 在UL及DL的DPCH中,含有由规定的比特系列组成的专用导频信号(Pilot)。 [0081] In the UL and the DL DPCH, the dedicated pilot comprising a series of bits consisting of a predetermined pilot signal (Pilot). UL的DPCH发送功率由快速闭环发送功率控制来进行控制,在该控制中,基站利用UL的DPCH的专用导频信号来测定DPCH的接收SIR,并将该测量值与该基站具有的目标SIR进行比较。 The UL DPCH transmission power by the fast closed loop power control to control, in this control, the base station uses the dedicated pilot UL DPCH pilot signal reception SIR of the DPCH is measured, and the measured values ​​with the base station having a target SIR Compare. 然后,当该测量值比目标SIR小时,利用DL的DPCH 1、2将“功率增加”的TPC比特通知给移动台3,除此之外的时候将“功率降低”的TPC比特通知给移动台3。 Then, when the measured value than the target SIR hours, using the DL DPCH 1,2 to "increase power" TPC bit is notified to 3, except when the "power down" the mobile station the TPC bit to the mobile station 3. 此外,该目标SIR的值是从无线网络控制站RNC(图10中的10)发过来的。 In addition, the value of the target SIR from the RNC radio network controller (10 in FIG. 10) sent over.

[0082] 各基站发送HS-PDSCH,该HS-PDSCH为比DPCH高速的信道,以比DL的DPCH大的功率发送。 [0082] Each base station transmits the HS-PDSCH, the HS-PDSCH DPCH than the high-speed channel, transmitted in the DL DPCH is greater than power. 各基站使用一个HS-PDSCH向多个移动台发送数据。 Each base station uses one HS-PDSCH transmits data to a plurality of mobile stations. RNC或者基站确定向各移动台进行数据发送的时间表,从而对每一个移动台以不同的时间表进行数据发送。 RNC or each base station determines the mobile station data transmission schedule to the mobile station for each transmitted data to different schedules. 即,举个例子来说,首先向移动台3进行HS-PDSCH的发送,当该发送结束后,向移动台4进行HS-PDSCH的发送,在该发送结束之后,向移动台5进行HS-PDSCH的发送。 That is, for example, first transmitting the HS-PDSCH to the mobile station 3, when the end of the transmission, the HS-PDSCH transmission to the mobile station 4, after the end of the transmission, to the mobile station for 5 HS- PDSCH transmission.

[0083] 从通信网络向移动台3发送的数据到达RNC后,RNC将该数据向移动台3设定DPCH的基站I或2发送。 [0083] After reaching the RNC from the mobile communication network 3 to the data transmitted, the RNC base station DPCH data set 3 or I 2 to the mobile station. 这里,数据被送入基站I。 Here, the data is sent to the base station I.

[0084] 上面是第一至第五实施例所有的共同动作,下面利用图2的顺序图对第一实施例进行解说。 [0084] The above first to fifth embodiments all common operation, following a first embodiment will be illustrated using the sequence diagram of FIG. 当应从通信网络向移动台(MS) 3发送的数据到达RNC后,RNC将该数据向移动台3设定DPCH的基站(BS)发送。 When should the data communication network to the RNC 3 transmits a mobile station (MS), RNC sends the data to the mobile station 3 is set DPCH base station (BS). 这里,将数据向基站I发送(步骤S10)。 Here, the transmission data (step S10) to the base station I.

[0085] 基站I对移动台3进行意为数据传送的预告(步骤Sll)。 [0085] The base station I to the mobile station data transmission means 3 of the notice (step Sll). 然后,基站I将与ULDPCH的接收质量相对应的SIR提高预定值(步骤S12)。 Then, the base station and the reception quality ULDPCH I corresponding to the predetermined value to improve the SIR (step S12). 此外,使以DL DPCH发送的TPC比特的发送功率增加预定值并进行发送(步骤S13)。 In addition, the transmission power of DL DPCH TPC bit to increase the transmission of the predetermined value and transmitted (step S13). 另外,在将用于平衡功率的基准功率提升一个预定值的同时,将DL DPCH的发送功率也提升一个预定值(步骤S14)。 Further, the reference power for the power balance of a predetermined lift value, while the transmission power of the DL DPCH will also enhance a predetermined value (step S14).

[0086] 该功率平衡是3GPP(第三代伙伴项目)所规定的,是为了在不影响闭环发送功率控制的程度内,通过慢慢地使DL DPCH的发送功率接近所述基准功率,使基站间的所述发送功率平衡。 [0086] The power balance is specified in 3GPP (Third Generation Partnership Project), to an extent that does not affect the closed loop transmission power control, access to the reference power by gradually making the transmission power of the DL DPCH, so that the base station the power balance between the transmission. 是将为进行该平衡调节所使用的基准功率在分组包发送基站I中提升预定值。 For the balance adjustment is carried out by using a predetermined reference power boosting value in the packet in the packet transmission base station I.

[0087] 在移动台3中,接收到来自基站I的数据传送预告后,只根据分组包发送基站I发送的TPC信号对自身发送的UL DPCH的发送功率进行控制(步骤S15)。 After [0087] In the mobile station 3, receives the data transmission notice from the base station I, the only control (step S15) UL DPCH transmission power of the base station transmits packet packet I transmitted TPC signals transmitted by itself.

[0088] 在上述状态下,利用HS-PDSCH从基站I向移动台3发送将数据分割成块之后的第一个分组包#1 (步骤S16),若在移动台3中正确接收到了该分组包#1,则利用HS-DPCCH向基站I发送ACK(步骤S17)。 [0088] In the above state, the HS-PDSCH transmitted from the base station I to the mobile station 3 divides the data into the first packet of the packet # 1 (step S16) after the block, the reception if the mobile station 3 correctly to the packet packet # 1, using the HS-DPCCH transmits ACK (step S17) to the base station I. 下面,同样地从基站I发送分组包#2(步骤S18),从移动台3向基站I发送ACK (步骤S19)。 Hereinafter, similarly to the packet transmitted from the base station I packet # 2 (step S18), 3 transmits ACK (step S19) from the mobile station to the base station I.

[0089] 在数据发送结束后,基站I通知移动台3数据结束(End of Data)(步骤S20)。 [0089] After the end of the data transmission, the base station notifies the mobile station 3 I data end (End of Data) (step S20). 响应数据发送结束,在基站I中进行返回处理,把在步骤S12〜S14中分别改变了的各数值恢复到初始状态(步骤S21)。 Response data transmitting end performs return processing in the base station I, the step S12~S14 are changed in the respective values ​​back to the initial state (step S21). 并且,在移动台3中,把在步骤S15中仅以分组包发送基站I的TPC来控制ULDPCH的发送功率的状态恢复为利用软交接中的所有基站的TPC来控制ULDPCH的发送功率这一初始状态(步骤S22)。 Further, in the mobile station 3, the base station only transmits packets I TPC packet in step S15 to control transmission power ULDPCH restore a state of all base stations using the TPC soft handover is controlled in this initial transmission power ULDPCH state (step S22). 此外,也可以代替数据结束(End of Data)的通知,当预定时间内没有分组包被发送过来时,返回到分组包发送前的初始状态。 Further, instead of the data end notification (End of Data), and when no packet is transmitted over the packet within a predetermined time, returns to the initial state before the packet transmission packet.

[0090] 如上述步骤S15所示,仅以分组包发送基站I的TPC信号来对移动台3自身发送的UL DPCH的发送功率进行控制,从而可以控制移动台的发送功率,使得分组包发送基站I中的UL DPCH满足目标质量,因而,以在该UL DPCH中加上了恒定的偏移功率值(公式(I)中的Λ)后的功率来发送的、HS-DPCCH中的ACK/NACK信号的接收质量也满足目标质量。 [0090] As shown in the above steps, only the base station transmits TPC signal packet I packet S15 to perform the transmission power of the UL DPCH transmitted from the mobile station 3 the control itself, thereby controlling transmission power of the mobile station, the base station transmits packets such that packets the UL DPCH power I satisfies the target quality, so as to add a constant offset power value (formula (I) in Lambda) after the UL DPCH transmitted to, HS-DPCCH in the ACK / NACK signal reception quality satisfies the target quality. 其结果是,ACK/NACK信号的接收精度提高了,且基于HS-DPSCH的数据发送的吞吐量也增加了。 As a result, the accuracy of receiving ACK / NACK signal is increased, and the HS-DPSCH based on the transmission data throughput also increases.

[0091] 此外,分组包发送基站I提高以DL DPCH发送的TPC信号的发动功率(步骤13),或者提高功率平衡的基准功率及DL DPCH的发送功率(步骤S14),由此,降低了分组包发送基站I所发送的TPC信号的接收差错率,并提高了移动台3中的发送功率控制的精度,因此,可以进一步提高分组包发送基站I中的ACK/NACK信号的接收质量。 Motor power (Step 13) [0091] In addition, base station I transmits a packet to improve the packet to DL DPCH TPC signals transmitted, or to improve the power and the reference power balancing the DL DPCH transmission power (step S14), thereby reducing the packet the base station transmits the packet error rate of the received TPC signals transmitted I, and improves the accuracy of transmission power control in the mobile station 3, therefore, possible to further improve the reception quality of the base station I transmits a packet in the packet an ACK / NACK signal. 此外,在分组包发送基站I中,通过提升UL DPCH的目标SIR (步骤S12),可以提高该基站I中的ACK/NACK信号的接收质量。 Further, the base station transmits the packet in the packet I, by increasing the target SIR UL DPCH (step S12), the base station can improve the reception quality of I ACK / NACK signal.

[0092] 根据第一实施例,不必如以往的第二方法那样改变时隙数据形式,并且,由于DPCH与HS-DPCCH的偏移功率值恒定,所以不会如以往的第一及第二方法那样由于DPCH的导频信号的接收质量降低而导致信道推断精度降低,从而不必向HS-DPCCH加入导频信号。 [0092] According to the first embodiment, it is not necessary as in the conventional method of a second data format is changed as the time slot, and, since the offset value of the power of the DPCH and the HS-DPCCH is constant, as does the first and second conventional methods as a degraded reception quality of the DPCH pilot signal resulting from the channel estimation accuracy is deteriorated so that no pilot signal is added to the HS-DPCCH.

[0093] 此外,在本第一实施例中,只在分组包收发过程中采用步骤S12〜S15的处理,在比分组包收发时间更大时间比例的、分组包收发时间以外的时间内,不进行这些处理,故不会在该时间内产生干涉增加的情况。 [0093] Further, in the first embodiment of the present embodiment, only the processing of step S12~S15 employed in a packet during packet transceiver, a larger proportion of time in time than packet transceiving packet, outside packet within the packet transmission and reception time, is not these processes is not generated in the case of interference increasing the time.

[0094] 此外,只通过步骤S15的移动台3中的动作就可以实现本发明的目的,而且将所述步骤S15的动作与步骤S12的分组包发送基站I中的动作组合实施也可以实现本发明的目的。 [0094] Further, only the object of the present invention can be achieved by the mobile station 3 in step S15 in the operation, and the operation of the embodiments in combination with the operation of step S15 step S12, the base station transmits packets I packets may also be implemented according to the present the object of the invention. 此外,在分组包发送基站I中,即使将步骤S13的动作或步骤S14的动作分别独立地进行,也可以实现本发明的目的。 Further, base station I transmits the packet in the packet, even if the operation of the operation of step S13 or step S14 are performed independently, object of the present invention may be practiced. 另外,只提高步骤S14的功率平衡的基准功率也可以。 In addition, the power balance only improve step S14 of the reference power can be.

[0095] 图3及图4分别示出了用于实现第一实施例的基站及移动台的示意性功能框图。 [0095] Figures 3 and 4 show a schematic functional block diagram for implementing the embodiment of a base station and a mobile station in the first embodiment. 参照图3,在基站中,来自天线11的接收信号通过天线转换器(DUP:双工器)12输入到接收部分13,进行放大、变频、解调等处理。 Referring to FIG. 3, the base station receives signals from antenna 11 through the antenna switch: an input (DUP duplexer) 12 to the receiving section 13 performs amplification, frequency conversion, demodulation processing and the like. 解调输出通过信道分离器14被分离为用户信息与各种控制信息。 Demodulation output by a channel separator 14 is separated into a user information and various control information. 这些控制信息被输入到控制部分(CPU) 15,图2的顺序图所示的步骤S12〜S14和S21等处理,根据预先存储在存储器16中的程序顺序来进行。 The control information is input to the control section (CPU) 15, the order of steps shown in FIG. 2 and FIG S12~S14 processing such as S21, is performed sequentially according to a program stored in the memory 16.

[0096] 另一方面,与移动台相对的用户信息和控制信息被在信道合成部分17进行合成,并通过放大部分18放大后提供给发送部分19,并进行调制和变频等处理,再通过天线转换器12及天线11发送出去。 [0096] On the other hand, user information and control information with the mobile station is opposite the channel section 17 in the synthesized synthesis, and supplied to the transmission section 19, and processing such as modulation and frequency conversion through the rear portion 18 enlarge, and then through an antenna converter 12 and the antenna 11 is sent out.

[0097] 参照图4,在移动台中,来自天线21的接收信号通过天线转换器22被提供给接收部分23,并进行放大、变频、解调等处理。 [0097] Referring to Figure 4, in a mobile station, the received signal from the antenna 21 is supplied to the receiving portion 23 through the antenna switch 22, and amplification, frequency conversion, demodulation processing and the like. 解调输出通过信道分离器24被分离为用户信息与作为控制信息的TPC信号。 Demodulation output by a channel separator 24 is separated into a user information and control information as the TPC signal. 该TPC信号被输入到控制部分(CPU) 25,图2的顺序图所示的步骤S15和S22的处理,根据预先存储在存储器26中的程序顺序来进行。 The TPC signal is input to the control section (CPU) 25, the order of steps shown in FIG. 2 and FIG S22 of S15, is performed in program order in the memory 26 stored in advance.

[0098] 另一方面,与基站相对的用户信息和控制信息在信道合成部分27进行合成,并通过放大部分28放大后提供给发送部分29,并进行调制和变频等处理,再通过天线转换器22及天线21发送出去。 [0098] On the other hand, user information and control information in the base station channel opposite to the synthesis section 27 synthesis, and amplified by the amplifying section 29 to the transmission, and modulation and frequency conversion processing section 28, and then through an antenna converter 22 and an antenna 21 is sent.

[0099] 接着,参照图5的动作顺序图来说明本发明的第二实施例。 [0099] Next, a second embodiment will be described with reference to embodiments of the present invention. FIG. 5 is an operation sequence diagram. 应从通信网络向移动台3发送的数据到达RNC后,RNC将该数据向移动台3设定DPCH的基站发送。 After the communication network to the RNC should the data transmitted from the mobile station 3, the data RNC 3 transmits a base station to set the DPCH to the mobile station. 这里,数据被发送至基站I (步骤S30)。 Here, the data is sent to the base station I (step S30).

[0100] 基站I向移动台3进行意为数据传送的预告(步骤S31)。 [0100] The base station I for notice (Step S31) intended for the data transmission to the mobile station 3. 然后,基站I将与ULDPCH的接收质量相对应的目标值SIR提升预定值(步骤S32)。 Then, the base station and the reception quality I ULDPCH SIR target value corresponding to the predetermined lift value (step S32). 另一方面,若移动台3从基站I收到数据传送预告后,则只根据分组包发送基站I所发送的TPC信号来控制自身发送的UL DPCH的发送功率(步骤S33)。 On the other hand, if the mobile station 3 receives the notice of data transmission from the base station I, only the packet from the packet I transmitted TPC signals transmitted to the base station controls the transmission power of the UL DPCH transmitted by itself (step S33). 此外,移动台3仅使DL DPCH的目标SIR增加预定值(步骤S34)。 In addition, the mobile station 3 so that only the DL DPCH target SIR by a predetermined value (step S34).

[0101] 另外,移动台3控制使得自身中的UL DPCH的发送功率控制的上升幅度比下降幅度大,使得控制步骤的增减非对称(步骤S35)。 [0101] Further, the mobile station 3 controls the transmission power such that the rise of the control of the UL DPCH itself larger than the decrease, increase or decrease such that the asymmetrical control step (step S35). 即,如果设增加步骤为APup,设减少步骤为APdown,则使得ΔΡιιρ> Δ Pdown。 That is, assuming that the step of increasing APup, reducing step is provided APdown, so that the ΔΡιιρ> Δ Pdown.

[0102] 另外,移动台3通过从分组包发送基站I发送的DL DPCH的接收SIR,生成用于DLDPCH的功率控制的TPC信号(步骤S36)。 [0102] Further, 3 TPC signal through the power control packet transmitted from the packet receiving SIR of the base station I transmits the DL DPCH, the mobile station generates DLDPCH (step S36).

[0103] 然后,利用HS-PDSCH从基站I向移动台3发送将数据分成块后的各分组包#1和#2(步骤537、539),利用HS-DPCCH从移动台3向基站I发送意为接收到了各分组包的ACK信号(步骤S38、S40)。 [0103] Then, the HS-PDSCH transmitted after the data packet of each packet into blocks # 1 and # 2 (step 537, 539), using the HS-DPCCH 3 transmitted from the mobile station to the base station I I from the base station to the mobile station 3 each intended to receive an ACK signal for the packets (step S38, S40). 数据发送结束后,基站I向移动台3通知数据结束(步骤S41)。 After data transmission, the base station to the mobile station 3 I data end notification (step S41). 响应该数据结束,在基站I中,将在步骤S32中改变了的值恢复为原样(步骤S42),并在移动台3中将在步骤S33〜S36中改变了的处理恢复为原样(步骤S43)。 In response to the data is ended, the base station I, the change in step S32 are restored to their original value back to the processing (step S42), and changes in steps S33~S36 3 in the mobile station is as in the (step S43 ). 此外,在本实施例中,也可以代替数据结束通知,使得当在规定时间内没有分组包发送过来时,就返回到分组包发送前的初始状态。 Further, in the present embodiment, instead of the data end notification, so that when there is no packet transmission over a packet time, returns to the initial state prior to packet transmission in a predetermined packet.

[0104] 在本第二实施例中,除进行与第一实施例的图2中的顺序图的步骤S12及SI 5相同的处(S32及S33)外,还可以在移动台3中,通过使DL DPCH的目标SIR增加(步骤S34),提高在移动台接收的TPC信号的接收质量,并提高UL上的发送功率控制的精度。 [0104] In the second embodiment according to the present embodiment, in addition to the sequence of steps performed in FIG diagram of the first embodiment of SI 2 S12 and at the same (S32 and S33) 5, but may also be in the mobile station 3, by so that the DL DPCH SIR target is increased (step S34), improving the reception quality of the TPC signal received at the mobile station, and to improve the accuracy of the transmission power of the UL control. 由此,提高分组包发送基站中的ACK/NACK信号的接收质量。 Accordingly, the packet transmitted packet to improve reception quality in the base station an ACK / NACK signal.

[0105] 此外,通过使移动台3中的UL DPCH的发送功率的控制步骤非对称,使得增加步骤比减少步骤大(步骤S35),从而可使发送功率增加,使之立即达到所需的接收质量。 [0105] Further, by making the mobile station transmission power control step of the 3 asymmetric UL DPCH, so as to increase the reducing step is greater than the step (step S35), thereby allowing the transmission power is increased, so as to receive immediately the desired quality. 因此,即使在分组包那样的短发送时间内也可以保证所需质量。 Therefore, even in short packet transmission time of the packet may be guaranteed that the required quality. 另外,通过来自分组包发送基站的DL DPCH的接收SIR生成TPC信号(步骤S36),由此使得该DL DPCH在移动台的接收质量变大,从而可正确地接收包含在其中的TPC信号,其结果是,可在基站I中正确接收从移动台发送的HS-DPCCH。 Further, by receiving the generated SIR DL DPCH from the base station of the TPC packet transmitted packet signal (step S36), thereby making the reception quality of DL DPCH in the mobile station becomes large, thereby correctly receiving a signal in which the TPC, which As a result, the received HS-DPCCH transmitted from the mobile station in the base station correctly I below.

[0106] 此外,在第二实施例中,仅在分组包发送中采用步骤S32〜S36的处理,在时间比例比分组包收发时间大的、分组包收发时间以外的时间内,不进行这些处理,因而在该时间内不会产生干涉增加。 [0106] Further, in the second embodiment, the processing steps S32~S36 using only packet transmission in a packet, the packet transmitting and receiving the time scale score time a large group, other than a packet within the packet transmission and reception times, these processes are not performed increases, thus does not produce interference in the time.

[0107] 且在移动台3中,即使只是分别独立实施步骤S34的动作和步骤S36的动作,也可实现本发明的目的。 [0107] and the mobile station 3, which are independent of operation even if only embodiment and the operation of step S34 step S36, may also achieve the object of the present invention. 此外,分组包发送基站I中的步骤S32的动作,与移动台3中的步骤S33的动作组合之后,再结合移动台3中的步骤S35的动作,也可以实现本发明的目的。 Further, the packet transmission packet in step S32, I is the base station operation, and after the mobile station 3 in the step S33 is combination of actions, combined with the operation of mobile station 3 in step S35, the object of the present invention may be practiced.

[0108] 显而易见,图3及图4所示的示意性功能框图也适用于用来实现本第二实施例的基站及移动台。 [0108] Obviously, a schematic functional block diagram shown in FIG. 3 and FIG. 4 is also applicable to a base station and a mobile station for implementing the second embodiment of the present embodiment.

[0109] 接着,参照图6及图7的流程,对本发明的第三实施例进行说明。 [0109] Next, with reference to the flow of FIG. 6 and FIG. 7, a third embodiment of the present invention will be described. 图6是移动台的动作流程,响应来自分组包发送基站I的数据传送预告(步骤S5 1),移动台3根据连接基站1、2以预定的发送功率发送的DL的质量确定HS-DPCCH的偏移功率Λ SHO的增量。 FIG 6 is an operation flow of the mobile station, in response to a data transmission notice packet transmitted from the packet I, the base station (step S5 1), the mobile station 3 is determined in accordance with the quality of the HS-DPCCH DL is connected to the base station 1 to a predetermined transmission power transmitted increment power Λ offset the SHO. 具体地说,测定来自软交接状态下的连接基站1、2的公共导频信号的接收功率RP1、RP2(步骤S52),并判断DL的质量。 Specifically, the base station measures the received power from the connected RP1 soft handover state in the common pilot signal pilot 1, RP2 (step S52), and determines the quality of the DL.

[0110] 根据该接收功率RP1、RP2,确定HS-DPCCH的偏移功率Λ SHO的增量(步骤S53)。 [0110] According to the reception power RP1, RP2, determining the HS-DPCCH offset power Λ SHO increment (step S53). 具体地说,可通过下式计算出偏移功率ASHO: Specifically, the offset can be calculated by the power ASHO:

[0111] ASHO = AN0N-SH0+101og10{max(RPl, RP2)/RP1} (dB) (2)。 [0111] ASHO = AN0N-SH0 + 101og10 {max (RPl, RP2) / RP1} (dB) (2).

[0112] 这里,ΛNON-SHO是非软交接状态时的偏移功率,max(RPI, RP2)表示RPl,RP2中最大的那个。 [0112] Here, when a power offset ΛNON-SHO non-soft handover state, max (RPI, RP2) represents RPl, RP2 that maximum.

[0113]因此,如果 RPl > RP2,则Δ SHO = NON-SHO,如果RPl < RP2,则[0114] Δ SHO = Δ N0N-SH0+101og10 (RP2/RP1) (3), [0113] Thus, if RPl> RP2, the Δ SHO = NON-SHO, if RPl <RP2, the [0114] Δ SHO = Δ N0N-SH0 + 101og10 (RP2 / RP1) (3),

[0115] 右边的第二项为偏移功率的增量。 [0115] The second term of the right side of the delta power offset. 使偏移功率只增加该确定的增量,并发送HS-DPCCH (步骤S54)。 The offset is only incremental power increase of the determination, and transmits the HS-DPCCH (step S54).

[0116] 图7是本第三实施例中的分组包发送基站的动作流程。 [0116] FIG. 7 is an operation flow of a base station packet transmission packet in the third embodiment of the present. 此外,该图7的流程与下面的第四实施例的基站的动作是相同的。 In addition, the operation of the base station in the fourth embodiment the following processes and 7 is the same as FIG. 参照图7,响应HS-DPCCH的接收(步骤S61),进行ACK/NACK的判定,如判定为“NACK” (在步骤S62中为“N”),则进行普通处理(步骤S63)。 Referring to FIG 7, in response to receiving the HS-DPCCH (step S61,), for the ACK / NACK determination, if the judgment is "NACK" (in step S62 is "N"), the normal processing is performed (step S63). 即如果是“NACK”,则进行相应分组包的再次发送。 I.e., if it is "NACK", the corresponding packet retransmission packet is performed.

[0117] 如在步骤S62中判断为“ACK”,则根据HS-DPCCH的ACK/NACK的接收判定结果的可信度来进行确定UL中的分组包发送的动作。 [0117] The determination in step S62 is "ACK", it is determined that the reliability of the result of the HS-DPCCH according to the received ACK / NACK packet to perform an operation determination packet transmitted in the UL. 即,检测ACK/NACK的接收判定结果的可信度(步骤S64),比较该可信度与预定阈值(步骤S65)。 That is, detecting the ACK / NACK reception reliability of the determination result (step S64), comparing the confidence value with a predetermined threshold (step S65). 如果可信度比阈值高,则转为普通处理(步骤S63),如果低,则与ACK/NACK信号无关而通常判断为NACK (步骤S66)。 If higher reliability than the threshold value, then converted to the normal processing (step S63,), if low, the ACK / NACK signal is determined regardless generally NACK (step S66). 因此,进行相应分组包的再次发送(步骤S67)。 Thus, the corresponding packet retransmission packet (step S67).

[0118] 根据本第三实施例,与连接基站中的其他基站相比,根据分组包发送基站的UL的传播损耗(线路质量),即如果传播损耗大,则设定较大的偏移功率(ASHO),如果小则设定较小的偏移功率,从而可以补偿传播损耗所导致的ACK/NACK信号的接收质量的降低。 [0118] According to a third embodiment of the present embodiment, as compared with other base stations connected to base station, according to the UL propagation loss (channel quality) of the base station transmits a packet the packet, i.e., if the propagation loss is large, the power offset is set larger (ASHO), if small is set small offset power, which can compensate for the reduced quality of the received ACK / NACK signal caused by the propagation loss. 此夕卜,在分组包发送基站中的ACK/NACK判断中,如果将NACK误判定为ACK,则会产生分组包丢失,故当判断为ACK时,根据接收判定结果的可信度而常常将其判定为NACK,从而可减少NACK的差错率并降低分组包丢失率,进而可提高吞吐量。 When this Bu Xi, the ACK packet in the packet transmission base station / NACK determination, if the erroneously determined NACK is ACK, packet loss will be generated, it is determined if an ACK, according to the credibility of the determination result and reception often it is determined that the NACK, NACK error rate can be reduced so as to reduce the packet loss rate and, in turn, can improve the throughput.

[0119] 在本实施例中,处于软交接状态的基站数为2,当为3以上时,显然可知上述公式 The number of the base station [0119] In the present embodiment, in the soft handover state is 2, when 3 or more, the above equation is apparent

(2)中的maxlRPl,RP2}就为max{RPl, RP2, RP3,.......}。 (2) maxlRPl, RP2} it is max {RPl, RP2, RP3, .......}.

[0120] 此外,图6及图7的动作当然可通过图3及图4中示出的各功能块来实现。 [0120] In addition, the operation of FIGS. 6 and 7 may of course be shown in FIGS. 3 and 4 by respective functional blocks to implement.

[0121] 下面对本发明的第四实施例进行说明。 [0121] Next, a fourth embodiment of the present invention will be described. 图8是本第四实施例的移动台的动作流程图。 FIG 8 is an operation flowchart of the mobile station according to a fourth embodiment. 响应数据传送预告(步骤S71),移动台根据软交接中的基站数N来确定HS-DPCCH的偏移功率ASHO的增量(步骤S72)。 Trailer response to the data transfer (step S71), the mobile station determines a power offset of HS-DPCCH ASHO increment (step S72) The number of base stations in the soft handover N. 具体来说,是根据下式计算出偏移功率, Specifically, the offset power is calculated according to the following formula,

[0122] ASHO= AN0N-SH0+101og10N(dB) (4), [0122] ASHO = AN0N-SH0 + 101og10N (dB) (4),

[0123] 由此,偏移功率的增量为公式⑷右边的第二项。 The second [0123] Thus, the power of the right delta offset of formula ⑷. 以增加了该增量的公式⑷的偏移功率来发送HS-DPCCH (步骤S73)。 To increase the formula ⑷ the incremental offset power to transmit HS-DPCCH (step S73). 本第四实施例中的分组包发送基站的动作流程与图7的动作流程相同。 FIG operation flow of a packet in the packet transmission base station according to a fourth embodiment of the present operation flow 7 is the same.

[0124] 在本第四实施例中,具有如下效果。 [0124] In a fourth embodiment according to the present embodiment has the following effects. 即,如果软交接中的基站数N变大,则DPCH的接收分集增益变大,故DPCH的发送功率降低,但是在移动台中,如果该数N变大,由于与之相应地HS-DPCCH的偏移功率的增量也变大,因而HS-DPCCH的接收质量不管软交接中的基站数是多少,都可以控制为所需值。 That is, if the number of the base station soft handover in N increases, the DPCH receiving diversity gain becomes large, so that the DPCH transmit power is reduced, but the mobile station, if the number N is large, since corresponding thereto to the HS-DPCCH the incremental offset power also becomes large, and therefore the reception quality of HS-DPCCH in soft handover regardless of the number of base stations is much, can be controlled to a desired value.

[0125] 此外,基站接收移动台发送的比特系列信号,并进行ACK或者NACK的判断,但是当比特系列的接收质量较差时,其信号信息的可信度降低。 [0125] In addition, the base station receives the mobile station transmitted signal series of bits, and the ACK or NACK judgment, but when the reception quality is poor series of bits, which is reliability information of the signal is reduced. 此时,不管是否从移动台发送了NACK,都判断为ACK。 At this time, regardless of whether the NACK transmitted from the mobile station are determined for the ACK. 因此,在本发明中的数据发送基站(分组包发送基站)中,根据HS-DPCCH的ACK/NACK的接收判定结果的可信度而常常判断为NACK。 Thus, the base station transmits data (packet packet transmitting base station) in the present invention, the HS-DPCCH according to the credibility of the ACK / NACK reception determination result and often determines NACK. 由此,可减少NACK的差错率,降低分组包丢失率。 Thereby, the NACK error rate can be reduced, reducing the packet loss rate. 另外,由于不经常进行HS-DPCCH的ACK/NACK的接收判定结果的可信度的计算,只是在判断为ACK时才进行计算,因而可降低用于所述计算的负荷。 In addition, calculating the reliability of the HS-DPCCH since the ACK / NACK reception determination result infrequently, is determined only when the ACK is calculated, and thus can reduce the load for the calculation.

[0126] 此外,在本第四实施例中,在移动台中,只在分组包发送中应用图8的处理,由于在时间比例比分组包发送时间大的、分组包发送时间以外的时间内,不进行这些处理,因而在该时间内不会产生干涉增加。 [0126] Further, in the fourth embodiment according to the present embodiment, the mobile station of FIG. 8 only in processing application packet transmission packet, since the packet transmission time ratio of time is greater than packet, the packet other than the packet transmission time period, these processes are not performed, and thus does not interfere in the increase of time.

[0127] 上述第四实施例的动作显然也可以通过图3及图4所示的各功能块来实现。 [0127] Each functional block of the operation of the fourth embodiment can obviously shown by FIG. 3 and FIG. 4 is achieved.

[0128] 下面对本发明的第五实施例进行说明。 [0128] Next, a fifth embodiment of the present invention will be described. 在第五实施例中,上行链路的DPCH如图10所示,在无线网络控制站(RNC) 10中进行连接基站1、2之间的分集合成,同时该DPCH常通过快速闭环发送功率控制而被控制为预定的接收质量。 In the fifth embodiment, the uplink DPCH shown in Figure 10, the synthesis diversity between the base station 1 is connected in the wireless network control station (the RNC) 10, while the DPCH is often closed loop transmission power control by flash It is controlled to a predetermined reception quality. 具体地说,移动台根据从基站发送的TPC比特来增减DPCH的发送功率,DPDCH的发送功率HFDCH以在DPCCH的发送功率TOPCCH上加上预定的偏移值Λ I而得的功率来进行发送。 Specifically, the mobile station according to the TPC bit transmitted from the base station decreases the transmission power of the DPCH, the transmission power of the DPDCH HFDCH to adding a predetermined offset value Λ I obtained power on the DPCCH transmit power to transmit TOPCCH . S卩,以下面的关系发送: S Jie, send the following relationship:

[0129] PDPDCH = PDPCCH+ Δ I (dB) (5)。 [0129] PDPDCH = PDPCCH + Δ I (dB) (5).

[0130] 另外,HS-DPCCH的发送功率PH以在该DPCCH的发送功率IWCCH上加上预定的偏移值Λ 2而得的功率来进行发送。 [0130] Further, HS-DPCCH transmission power PH to add on the DPCCH transmission power IWCCH predetermined offset value Λ 2 obtained by power transmitted. S卩,以下面的关系发送: S Jie, send the following relationship:

[0131] PH = PDPCCH+ Δ 2 (dB) (6)。 [0131] PH = PDPCCH + Δ 2 (dB) (6).

[0132] 其中,在公式(5)及公式(6)中,各值为分贝值。 [0132] wherein, in the formula (5) and formula (6), each value decibel value.

[0133] 该动作与第一实施例实质上是相同的,但在本第五实施例中,当移动台的发送功率被限定为预定的最大值时,优先确保HS-DPCCH的发送功率,并抑制DroCH的发送功率。 [0133] The operation of the first embodiment are substantially the same, but in the fifth embodiment of the present embodiment, when the transmission power of the mobile station is defined as a predetermined maximum value, the transmission power to ensure that the priority of the HS-DPCCH, and DroCH of suppressing the transmission power. 除这点以外,都与第一实施例相同。 In addition to these points are the same as the first embodiment embodiment. 抑制DrocH的发送功率的控制在图4的移动台的控制部分25中进行。 DrocH suppression control transmission power in the mobile station control section 25 of FIG. 4.

[0134] 图9是本第五实施例中的DroCH的发送功率抑制的流程。 [0134] FIG. 9 is a transmission power in the fifth embodiment DroCH inhibition process. 参照图9,移动台接收TPC比特(步骤S81),计算DPCCH与HS-DPCCH的合计发送功率(步骤S82),计算可分配给DPDCH的最大发送功率(步骤S83)。 Referring to FIG. 9, the mobile station receives the TPC bit (step S81), calculates a DPCCH and HS-DPCCH total transmission power (step S82), calculates the maximum transmission power can be allocated to the DPDCH (step S83). 该DroCH最大发送功率是通过从发送功率的预定最大值中减去DPCCH与HS-DPCCH的合计发送功率而得到的。 The maximum transmission power is obtained by DroCH DPCCH and HS-DPCCH subtracted from a predetermined maximum total transmission power in the transmission power is obtained.

[0135] 然后,当通过公式(5)计算得到的DroCH的发送功率不超过DroCH最大发送功率时,将DPDCH的发送功率作为通过公式(5)计算出的值(步骤S85),当通过公式(5)计算得到的DrocH的发送功率超过DrocH最大发送功率时,抑制DrocH的发送功率使之为DrocH最大发送功率(步骤S86)。 [0135] Then, when the transmission power is calculated by the formula (5) obtained DroCH does not exceed DroCH maximum transmission power of the DPDCH transmission power as computed by Equation (5) (step S85), when by the formula ( 5 transmission power) calculated DrocH DrocH exceeds the maximum transmission power, the transmission power is suppressed so as DrocH DrocH the maximum transmission power (step S86).

[0136] 此外,作为抑制DroCH的发送功率的方法,当移动台的合计发送功率接近预定的最大值时,也可以暂时减小公式(5)中的偏移值Al的值。 [0136] Further, as a method of suppressing the transmission power DroCH, when the total transmission power of the mobile station is close to a predetermined maximum value, may be temporarily reduced offset value Al of the formula (5).

[0137] 在本第五实施例中,具有如下效果。 [0137] In the present embodiment, the fifth embodiment has the following effects. 即,当从移动台到基站的传播损耗大时,或者分组包发送基站接收的干涉波功率大时,移动台需要将HS-DPCCH以大发送功率发送,并将DPCCH与DroCH的发送功率的比保持恒定,由于移动台的发送功率达到预定的最大值,故不会使HS-DPCCH的发送功率充分增加,从而包含于HS-DPCCH中的ACK/NACK信号的接收质量可能降低。 That is, when the propagation from mobile to base station of a large loss, the base station transmits the packet or packets received interference wave power is large, the mobile station needs to send a large HS-DPCCH transmission power ratio and the transmission power of the DPCCH is DroCH remains constant, since the transmission power of the mobile station reaches a predetermined maximum value, so that the transmission power does not sufficiently increase the HS-DPCCH, HS-DPCCH contained in such an ACK / NACK signal reception quality may be reduced.

[0138] 但是,在本第五实施例中,当把移动台的发送功率限制为规定的最大值时,由于抑制了DroCH的发送功率,故可给HS-DPCCH分配的发送功率变大,从而减小ACK/NACK信号的接收质量降低的可能性。 [0138] However, in the fifth embodiment, when the transmission power of the mobile station is limited to a predetermined maximum value, due to the suppression of the transmission power DroCH, it can be allocated to the HS-DPCCH transmission power becomes large, reducing the likelihood of the reception quality of ACK / NACK signal is reduced. 其结果是,在分组包发送基站中提高了ACK/NACK信号的接收质量,并增加了基于HS-DPSCH的数据发送的吞吐量。 As a result, to improve the reception quality of ACK / NACK signal transmission packet in a packet in the base station, and increasing transmission of HS-DPSCH based on data throughput.

[0139] 此外,在第五实施例中,在移动台与多个基站设定专用信道的软交接状态下,如第一实施例的步骤S15所示,在分组包接收中,只用分组包发送基站的TPC信号来对移动台发送的UL DPCH的发送功率进行控制。 The [0139] Further, in the fifth embodiment, the mobile station and the plurality of base station sets a dedicated channel soft handover state, as in the first step of the embodiment illustrated embodiment, the packet received in the packet, only packets with packet S15 UL DPCH transmission power TPC signal transmitted to the base station to the mobile station transmits control. 此时,在该移动台与处于软交接状态的基站中,无论在分组包发送基站以外的基站中DPCCH与DPDCH的接收质量是否满足预定质量目标,由于分组包发送基站中的DPCCH与DroCH的接收质量不满足预定质量目标,所以存在移动台使DPCCH与DrocH的发送功率增加的情况。 In this case, the mobile station and a base station in a soft handover state, regardless of whether the reception quality of the packet in the packet DPCCH and DPDCH, the base station other than the base station satisfying a predetermined transmission quality target, the base station receives the transmitted packet since the packet in the DPCCH and DroCH quality fails to meet predetermined quality objectives, there is a case where the mobile station with the transmission power of the DPCCH DrocH increased. 此时,将DrocH的发送功率增加到所需以上。 In this case, the transmission power DrocH increased more than necessary. 这是由于在处于软交接状态的多个基站中接收到的DPDCH分集合成的缘故。 This is due to a plurality of base stations received in a soft handover state of the DPDCH diversity combining sake. 因此,在软交接状态下,移动台的发送功率被限制为预定最大值的可能性较高。 Thus, in a soft handover state, the transmission power of the mobile station is limited to a predetermined maximum value higher possibility.

[0140] 但是,在本第五实施例中,通过抑制DroCH的发送功率而使HS-DPCCH的发送功率不被移动台的发送功率的最大值所限制。 [0140] However, in the fifth embodiment, the HS-DPCCH transmission power by suppressing the transmission power DroCH is not limited by the maximum transmission power of the mobile station. 因此,特别是在软交接状态下,在分组包发送基站中提高ACK/NACK信号的接收质量的效果增大。 Thus, especially in the soft handover state, the effect of improving the reception quality of an ACK / NACK signal is increased in the packet in the packet transmission base station.

[0141 ] 如上所述,根据本发明,可获得如下效果:即使当移动台通过处于软交接状态而与多个基站设定DPCH的状态时,由于分组包发送基站能够以足够的质量接收HS-DPCCH,由此减少了包含于该HS-DPCCH中的、表示可否正常接收分组包的ACK/NACK信号的差错率,没有分组包丢失,实现了吞吐量的提高。 [0141] As described above, according to the present invention, the following effects: Even when the state of the DPCH when the mobile station is set by the plurality of base stations in a soft handover state, the base station transmits the packet since the packet can be received with sufficient quality HS- the DPCCH, thereby reducing included in the HS-DPCCH is, the error rate indicates whether the packet normally received packet ACK / NACK signal, there is no packet loss, to achieve improved throughput.

[0142] 此外,只是在软交接状态中且在分组包收发中,才进行上述ACK/NACK信号差错率的降低控制,在时间比例比分组包收发时间要大的分组包等待中,不进行该控制,从而不会导致发送功率的增加就可降低ACK/NACK信号的差错率,并且UL/DL DPCH的软交接时的分集效应也不会有任何损失。 [0142] Further, only in the packet and the packet transmitting and receiving only the above-described control for reducing ACK / NACK signal error rate in a soft handover state, the score at the time scale to a large set of packet transmission and reception times of packets waiting in the packet, not the control, resulting in no increase in transmission power can reduce the error rate ACK / NACK signal, and the diversity effect during soft handover UL / DL DPCH will not have any loss.

[0143] 工业实用性: [0143] Industrial Applicability:

[0144] 本发明可适用于包括移动台及基站的蜂窝系统,特别是适用于通过HS-DPCCH从移动台向基站发送ACK/NACK的系统。 [0144] The present invention is applicable to a cellular system comprising a mobile station and a base station, particularly adapted to transmit ACK / NACK to the base station system from a mobile station via HS-DPCCH.
