技术领域 FIELD

[0001] 本发明涉及下行分量载波的标识及上报技术,尤其涉及一种高级长期演进系统(LTE-A, Long Term Evolution-Advanced)中下行分量载波的标识方法及同步下行分量载波的上报方法与装置。 [0001] identification relates to the downlink component carrier of the present invention, and reporting technology, particularly to a Long Term Evolution Advanced (LTE-A, Long Term Evolution-Advanced) in the downlink component carrier and the method of identifying the synchronization method of reporting downlink component carrier and device.

背景技术 Background technique

[0002] LTE-A系统是长期演进(LTE,Long Term Evolution)系统的下一代演进系统。 [0002] LTE-A system is a long term evolution (LTE, Long Term Evolution) system is an evolved next-generation system. 图1为LTE-A系统中载波聚合及分量载波关系的示意图,如图1所示,LTE-A系统采用载波聚合(Carrier Aggregation,又称载波聚集)技术扩展传输带宽,以获得更高的数据速率。 1 is a schematic system LTE-A component carriers and carrier aggregation relationship, shown in Figure 1, LTE-A system adopts carrier aggregation (Carrier Aggregation, known as carrier aggregation) technique bandwidth expansion, in order to obtain higher data rate. 每个聚合的载波称为一个分量载波(ComponentCarrier)。 Each polymeric carrier is called a component carrier (ComponentCarrier). 分量载波在频谱上可以是连续的,也可以是非连续的。 On component carrier spectrum may be continuous, it may be non-contiguous.

[0003] LTE-A系统的下行传输带宽由多个下行分量载波聚合而成;上行传输带宽可能只包含一个上行分量载波,也可能由多个上行分量载波聚合而成。 [0003] downlink transmission bandwidth LTE-A system is polymerized from a plurality of downlink component carriers made; uplink transmission bandwidth may contain only one uplink component carrier, the polymerization may also be formed by a plurality of uplink component carriers. 即系统上、下行带宽可能包含不同数目的分量载波。 That is on the system, downlink bandwidth may comprise a different number of component carriers. 即使系统上、下行分量载波的数目相同,对某个用户终端(UE,UserEquipment)而言,其下行接收带宽包含的分量载波数同上行发送带宽包含的分量载波数也可能不同。 Even on the system, the same number of downlink component carriers, for a user equipment (UE, UserEquipment), the number of carrier components contained in its reception bandwidth of downlink carriers row above the number of components included in the transmission bandwidth may be different. 上、下行分量载波数量不等的情况称为非对称载波聚集。 On an unequal number of downlink component carriers called asymmetric carrier aggregation.

[0004] LTE-A系统的下行分量载波上可以发送同步信号(Synchronization Signal)并承载有广播信道。 [0004] may transmit a synchronization signal (Synchronization Signal) on the downlink component carrier LTE-A system and carries a broadcast channel. 此处一个下行分量载波上的“广播信道”是指承载了某个分量载波或某几个分量载波或整个小区的广播消息的信道,这些消息可以被小区内的全部用户终端或小区内具有某一相同属性的所有用户终端所接收。 Here a downlink component "broadcast channel" refers to a carrier carrying on a certain component carrier or a component carrier or a few channels throughout the cell broadcast message, the message may be all the user terminals have a cell or within the cell all user terminals received an identical attribute. 另外,广播信道可以指物理层的物理信道,也可以指介质访问控制子层(MAC子层)的传输信道或无线资源管理子层(无线资源控制(RRC, Radio Resource Control)层)的逻辑信道。 Further, the broadcast channel may refer to physical channels at the physical layer, it may also refer to a medium access transmission channel control sublayer (MAC sub-layer) or radio resource management sub-layer (Radio Resource Control (RRC, Radio Resource Control) layer) logical channel . 广播信道承载的广播消息也称为系统信息(SystemInformation)。 A broadcast channel carrying the broadcast message is also referred to as system information (SystemInformation).

[0005] LTE系统的系统信息由主信息块(MIB,Master Information Block)和一系列系统信息块(SIB, System Information Block)承载。 [0005] system information of the LTE system and a number of system information blocks (SIB, System Information Block) carried by a master information block (MIB, Master Information Block). 其中,MIB包含一些最基本的系统信息,包括下行系统带宽、物理下行HARQ指示信道(PHICH)的配置信息、系统帧号等。 Wherein, the MIB contains some basic information system, comprising a downlink system bandwidth, downlink physical HARQ indicator channel (PHICH) configuration information, system frame number and the like. MIB在物理广播信道(PBCH, Physical BroadcastChannel)上周期发送。 MIB period is sent on a physical broadcast channel (PBCH, Physical BroadcastChannel).

[0006] SIB 根据内容分为11 类(SystemlnformationBlockType I 〜11),并在物理下行共享信道(PDSCH, Physical Downlink Shared Channel)上发送。 [0006] SIB The content is divided into 11 classes (SystemlnformationBlockType I ~11), and the shared channel (PDSCH, Physical Downlink Shared Channel) transmitted in a physical downlink. 其中,SystemInformationBlockType2 (SIB-2)包含了该小区的无线资源配置信息(radioresource configurationinformation),其中包括上行载波的频点信息(可缺省)、上行系统带宽,以及随机接入配 Wherein, SystemInformationBlockType2 (SIB-2) includes radio resource configuration information of the cell (radioresource configurationinformation), which includes frequency information of uplink carriers (available default), an uplink system bandwidth, and a random access with

置参数。 Configuration parameters.

[0007] 图2为LTE系统中随机接入的流程图,如图2所示,用户终端根据SIB-2中的随机接入配置参数,在选定的物理随机接入信道(PRACH, Physical RandomAccess Channel)上向基站发送随机接入前导(Random Access Preamble)。 [0007] FIG 2 is a flowchart of a random access in the LTE system, shown in Figure 2, the user terminal configuration parameters SIB-2 in the random access, at the selected physical random access channel (PRACH, Physical RandomAccess on Channel) transmits a random access preamble to a base station (random access preamble). 基站接收到随机接入前导后,利用其中的随机接入前导序列,计算定时提前量,并向该用户终端分配用于下一步传输的信道资源和小区无线网络临时标识号(C_RNTI,Cell Radio Network Temporary Identifier),经物理下行共享信道发送,称为随机接入响应(Random Access Response)。 The base station after receiving the random access preamble, wherein the random access preamble sequence to calculate a timing advance, to channel resources assigned to the terminal and a cell radio network temporary identity number (C_RNTI, Cell Radio Network for the next transmission of the user Temporary Identifier), by transmitting a physical downlink shared channel, known as a random access response (random access response). 用户终端在收到随机接入响应后,按照随机接入响应中的信道资源分配信息在物理上行共享信道(PUSCH, Physical Uplink Shared Channel)上发送首次调度上行传输(First scheduledULtransmission,简写为scheduled transmission,又称为Message 3,简写为Msg 3)。 The user terminal after receiving the random access response, the channel resource allocation information according to the physical uplink shared random access response transmitting first uplink transmission scheduling (First scheduledULtransmission the channel (PUSCH, Physical Uplink Shared Channel), abbreviated as scheduled transmission, also known as Message 3, abbreviated as Msg 3). Msg3根据触发该随机接入过程的事件不同而包含有不同的信息,包括比如RRC连接请求(RRCConnection Request)、C_RNTI等等。 Msg3 different events triggering the random access procedure includes different information, including, for example an RRC connection request (RRCConnection Request), C_RNTI like. 当该随机接入过程是基于竞争的,基站收到Msg 3后还要按其内容反馈竞争解决消息(ContentionResolution)给用户终端,称为Message 4,简写为Msg 4。 When the random access procedure is contention-based, the base station 3 even after their receipt Msg Content feedback contention resolution message (ContentionResolution) to the user terminal, called Message 4, abbreviated as Msg 4.

[0008] LTE系统使用ZadofT-Chu (简称ZC)序列的循环移位序列作为随机接入前导序列。 [0008] LTE system ZadofT-Chu (referred ZC) sequence cyclic shift as the random access preamble sequence. 这些ZC序列又称为根序列,这些循环移位序列又称为零相关区域(ZCZ,Zero CorrelationZone)序列。 These sequences, also known as a root ZC sequence, the cyclic shift sequence, also known as zero correlation zone (ZCZ, Zero CorrelationZone) sequence. 基站在SIB-2中的随机接入配置参数中通知用户终端本小区PRACH可以使用的第一条ZC序列的逻辑索引以及循环移位的步长(即循环移位量)。 The first base station configures the logical index of the ZC sequence informing the user terminal of the present cell PRACH parameters may be used in SIB-2 and a random access step size of cyclic shift (i.e. cyclic shift amount). 用户终端根据某种映射规则从第一条根序列的逻辑索引得到该序列的物理索引,然后根据循环移位量以及一定的“循环移位限制规则”生成可用的ZCZ序列。 User terminals to obtain the physical index of the sequence from the first sequence of logical root indexes according to a certain mapping rule, and "cyclic shift restriction rule" according to certain cyclic shift amount and the generated available ZCZ sequences. 这些循环移位限制规则是由循环移位限制标识使能的。 These cyclic shift restriction rule is identified by a cyclic shift limitations enabled. 如果ZCZ序列的数量少于门限值T(LTE系统中,T = 64),则用户终端自动递增序列逻辑索引,利用下一条ZC序列继续生成ZCZ序列,直到ZCZ序列的总数等于上述门限值为止。 If the number of ZCZ sequences is less than the threshold value T (LTE system, T = 64), the user terminal automatically increments the index sequence logic, continue generating ZCZ sequences using the ZC sequence a, ZCZ sequences until the total number equal to said threshold value until. 所生成的T条ZCZ序列按照生成的先后顺序标号,称为随机接入前导序列号,序列号取值为0,1,...,T-1。 The T-bar ZCZ sequences generated according to the generated reference sequence, called a random access preamble sequence number, the sequence number value of 0,1, ..., T-1. 最后,用户终端在所有生成的可用ZCZ序列中按一定的规则选择一条作为随机接入前导序列发送。 Finally, the user terminal is available ZCZ sequences generated according to certain rules as to select a random access preamble sequence transmitted.

[0009] 在LTE-A系统中,多个下行分量载波上的系统信息可能通知了同一个上行分量载波的频点和带宽信息,即多个下行分量载波可能对应于同一个上行分量载波。 [0009] In the LTE-A system, a plurality of system information on the downlink component carriers may be notified of the same uplink component carrier frequency and bandwidth information, i.e., a plurality of downlink component carriers may correspond to the same uplink component carrier. 在随机接入过程中,当基站检测到在这个上行分量载波上发送的随机接入前导序列时,基站无法确定发送该信号的用户终端同步在哪一个下行分量载波上。 In the random access procedure when the base station detects the random access preamble sequence transmitted on the uplink component carriers, the base station can not determine the user terminal transmits the signal on which a synchronization downlink carrier component. 于是,基站需要在所有对应的下行分量载波上发送对应于同一个前导的随机接入响应。 Thus, the base station needs on all of the corresponding downlink component carrier corresponding to the same transmitting a random access preamble response. 同理,当基站检测到在这个上行分量载波上发送的Msg 3时,基站无法确定发送该信号的用户终端同步在哪一个下行分量载波上。 Similarly, when the base station detects 3:00 transmitted on the uplink component carrier Msg, the base station can not determine the user terminal transmits the synchronization signal in which a downlink component carrier. 于是,基站需要在所有对应的下行分量载波上发送竞争解决消息Msg 4。 Thus, the base station needs to send a contention resolution message Msg 4 on all of the corresponding downlink component carrier. 如果随机接入过程结束后,基站仍无法确定该用户终端所同步的下行分量载波,后续的下行信号和/或下行信令可能也需要在多个下行分量载波上发送。 If the random access procedure ends, the base station still can not determine the synchronized downlink component carrier of the user terminal, a subsequent downlink signal and / or downlink signaling may need to be sent on a plurality of downlink component carriers. 这将造成系统资源的严重浪费。 This will cause a serious waste of system resources.

[0010] 因此,在LTE-A系统中,基站如何确定在哪个下行分量载波上发送随机接入响应和/或竞争解决消息Msg 4成为一个亟待解决的问题。 [0010] Accordingly, the LTE-A system, how to determine the base station transmits the random access response and / or a contention resolution message Msg 4 becomes a serious problem in which downlink component carrier.
