Description

一种TD-SCDMA系统HSDPA中高阶调制上行信令传输方法技术领域 One kind of TD-SCDMA system the uplink signaling in HSDPA high order modulation transmission TECHNICAL FIELD

本发明涉及3G移动通信系统中的上行信令传输方法,尤其涉及一种TD-SCDMA系统(时分同步码分多址系统)的HSDPA (高速下行分组接入)中的利用哈达码编码的高阶调制上行信令传输方法。 The present invention relates to a method for transmitting uplink signaling 3G mobile communication system, and more particularly to a system, TD-SCDMA (Time Division Synchronous Code Division Multiple Access system) HSDPA (High Speed ​​Downlink Packet Access) using a Hadamard encoded higher order modulating uplink signaling transmission method.

背景技术 Background technique

随着移动多媒体业务的增多,第三代移动通信系统2Mb/s的传输速率将不能满足要求,发展具有更大容量和更大比特传输速率的移动通信系统成为必然。 With the increase of mobile multimedia services, third generation mobile communication system 2Mb / s transmission rate will not meet the requirements, development of a mobile communication system having a larger capacity and a higher bit transmission rate of the inevitable. 因此,WCDMA (Wideband Code Division Multiple Access,宽带码分多址)、CDMA2000和TD-SCDMA (Time Division - Synchronous Code Division Multiple Access,时分同步码分多址)都在进行技术增强,以发展更高的业务速率、提供更多B3G的(后三代移动通讯)应用业务。 Thus, WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access), CDMA2000, and TD-SCDMA (Time Division - Synchronous Code Division Multiple Access, Time Division Synchronous Code Division Multiple Access) technology enhancements are performed to develop a higher business rates, provided (after generation mobile communications) more B3G of business applications. 在3GPP 标准中,基于UMTS标准提出了适用于WCDMA和TD-SCDMA的HSDPA (High Speed Downlink Packet Access,高速下行分组接入)。 In the 3GPP standard, based on the UMTS standard is proposed for WCDMA and TD-SCDMA of HSDPA (High Speed ​​Downlink Packet Access, High Speed ​​Downlink Packet Access). 在另一个标准化组织3GPP2中,也有类似的技术,它们是CDMA2000 1X EV-DO和EV画DV。 In another 3GPP2 standardization organization, has a similar technique, they are CDMA2000 1X EV-DO and EV Videos DV.

HSDPA是3GPP Release 5提出的一种增强方案,主要目的是对分组数据业务的高速支持,并且获得更低的时间延迟、更高的系统吞吐量和更有力的QoS保证。 HSDPA is an enhancement scheme proposed by 3GPP Release 5, the main purpose is to support high-speed packet data service and obtain a lower time delay, higher system throughput and more powerful QoS guarantee. 从技术角度来看,HSDPA通过引入高速下行共享信道(HS-DSCH)增强空中接口,并在UTRAN中增强相应的功能实体。 From a technical standpoint, HSDPA enhanced by introducing a high speed air interface downlink shared channel (HS-DSCH), and enhance the corresponding functional entities in the UTRAN. 从底层来看,主要是引入自适应调制编码(AMC)和H-ARQ (混合ARQ)技术来增加数据吞吐量。 From the bottom view, mainly the introduction of adaptive modulation and coding (AMC) and H-ARQ (Hybrid ARQ) technology to increase data throughput.

HARQ系统是在ARQ系统中引入一个FEC子系统,用来纠正经常出现 HARQ system is introduced into a FEC subsystem ARQ system, often used to correct

4的错误图样以减少重传次数,即在纠错能力范围内,自动纠正错误,超出纠错范围则要求发送端重新发送数据,这增加了系统的可靠性和传输效率。 Error pattern 4 in order to reduce the number of retransmissions, i.e. within the range of error correction capability, automatic error correction, the correction scope of the claims beyond the sending end to resend the data, which increases the reliability and transmission efficiency of the system. and also

就是说,H-ARQ能自动适应瞬间的信道条件提供细微的数据速率调整,而要选择一个适当的调制和编码方式则由AMC根据UE测量或网络端决定的信道条件获得。 That is, H-ARQ can automatically adapt to the instantaneous channel condition provides fine data rate adjustment, and to select an appropriate modulation and coding scheme obtained by the AMC channel conditions measured by the UE or the network decision. AMC在系统限制的范围内,才艮据信道质量情况的改变,调整调制与编码方式。 AMC range limits within the system, it changes according to channel quality Gen case letters, modulation and coding scheme adjustment. 在一个AMC系统中,处于有利位置的用户(通常是那些距离基站很近的用户),会被赋予较高的调制与编码方式(比如16QAM及1/2Turbo编码率);而处于不利位置的用户(通常是那些处于小区边界的用户),会被赋予较低的调制与编码方式(比如QPSK及1/2Turbo编码率)。 In an AMC system, a user in a good location (typically those close to the user from the base station), is given a higher modulation and coding scheme (such as 16QAM and 1 / 2Turbo coding rate); the user disadvantaged position (typically those users at the cell boundary) will be assigned a low modulation and coding scheme (such as QPSK and 1 / 2Turbo coding rate). 在AMC系统中,基站给每个用户的发送功率保持不变,对于位置较好的用户,信道条件好,系统可以向它提供高速率的数据业务,增加系统总吞吐量, 而要最大程度增强分组数据业务的传输能力,提高系统容量,需要引入更高的编码速率和更高阶调制方式(如32QAM, 64QAM, 256QAM )。 In the AMC system, the base station transmit power to each user remains unchanged, the position of the user for a better channel conditions are good, the system can provide high-rate data traffic to it, increases the total throughput of the system, and to maximize the enhancement packet data service transmission capacity, improve system capacity, the need to introduce a higher coding rate and higher order modulation scheme (e.g., 32QAM, 64QAM, 256QAM).

HSDPA的高速业务承载主要是靠高速下行共享信道(HS-DSCH )来实现传输,它是一个HSDPA的专用信道,而所有的相关底层的控制信息则由上行的HS-DSCH共享信息信道(HS-SICH)和下行的HS-DSCH共享控制信道(HS-SCCH )承载。 HSDPA high-speed traffic bearer mainly by high-speed downlink shared channel (HS-DSCH) to implement the transmission, which is a dedicated channel a HSDPA, whereas all the control information of the bottom by the uplink HS-DSCH shared information channel (HS- SICH) and the downlink shared control channel HS-DSCH (HS-SCCH) bearer. HS-SICH信道是HSDPA专用的上行控制信道, 是一个物理信道,用于反馈相关的上行信息,向基站(NodeB)传递用于支持H-ARQ的ACK/NACK信令,同时它还传输用于链路自适应的信道质量指示CQI。 HS-SICH channel is dedicated HSDPA uplink control channel is a physical channel, information related to uplink feedback, transmitted to the base station (the NodeB) for ACK / NACK signaling to support H-ARQ, while it for transmission link adaptation channel quality indicator CQI. CQI用于指示当前信道的质量,包括推荐传输块大小和推荐调制方式,Node B根据CQI决定下一次发送的传输格式。 CQI is used to indicate the quality of the current channel, including the recommended transport block size and modulation scheme recommended, a Node B transmits the transmission format according to the determined CQI. HS-SICH承载的信令有: 推荐调制方式(RMF)(1比特)Xrmfj,推荐传输块大小(RTBS)(6比特)x他s山xrtbs,2, ...,xrtbs,6,混合自动重传请求确认信息ACK/NACK(1比特)Xa^。 HS-SICH signaling bearers are: Recommended Modulation (RMF) (1 bit) Xrmfj, recommended transmission block size (RTBS) (6 bits) x s mountain he xrtbs, 2, ..., xrtbs, 6, hybrid automatic retransmission request acknowledgment information ACK / NACK (1-bit) Xa ^.
