Description

一种辅服务小区的资源的控制、管理方法和装置Method and device for controlling and managing resources of auxiliary service cell 技术领域Technical field
本发明实施例涉及但不限于通信领域,尤其涉及一种辅服务小区的资源的控制、管理方法和装置。The embodiments of the present invention relate to, but are not limited to, the field of communications, and in particular, to a method and a device for controlling and managing resources of a secondary serving cell.
背景技术Background technique
图1为相关技术中3GPP蜂窝移动家族制式中的长期演进***(LTE,Long Term Evolution)的***架构示意图,包括:核心网侧的移动管理实体(MME,Mobility Management Entity),服务网关(SGW,Serving GetWay),无线接入网侧的用户设备或称为终端(UE,User Equipment)和基站(eNodeB,简称为eNB),它们之间是Uu空中接口或称为空口,eNB和MME之间是S1-MME(S1for the control plane)接口,eNB和SGW之间是S1-U接口,eNB之间是X2-U(X2-User plane)和X2-C(X2-Control plane)接口。1 is a schematic diagram of a system architecture of a Long Term Evolution (LTE) system in a 3GPP cellular mobile family system, including: a mobility management entity (MME, Mobility Management Entity), and a service gateway (SGW, Serving GetWay), the user equipment on the radio access network side is called a UE (User Equipment) and a base station (eNodeB, eNB for short). The Uu air interface is called an air interface. The eNB and the MME are between the eNB and the MME. The S1-MME (S1 for the control plane) interface is an S1-U interface between the eNB and the SGW, and an X2-U (X2-User plane) and an X2-C (X2-Control plane) interface between the eNBs.
从LTE***Rel-10版本开始,为了提升终端的峰值速率,动态协调和利用多个授权载波小区间的无线资源,终端和基站能在多个授权载波上配置的小区内进行上下行通讯,实现多授权载波上的数据收发,此时基站给终端配置有多个服务小区:其中一个主服务小区Pcell(唯一承担PUCCH信道反馈的服务小区)+多个辅服务小区Scell(至少有PDSCH和/或PUSCH信道数据传输的服务小区)。这就是LTE载波聚合技术(CA,Carrier Aggregation),目前暂时限于对授权载波的聚合,且终端最大支持5个授权载波的聚合,即最大聚合带宽为5x 20M=100M。Starting from the Rel-10 version of the LTE system, in order to improve the peak rate of the terminal and dynamically coordinate and utilize the radio resources between the multiple licensed carrier cells, the terminal and the base station can perform uplink and downlink communication in the cells configured on the multiple authorized carriers. The data is transmitted and received on the multi-authorized carrier. At this time, the base station configures the terminal with multiple serving cells: one primary serving cell Pcell (the only serving cell that bears the PUCCH channel feedback) + multiple secondary serving cells Scell (at least PDSCH and/or PUSCH channel data transmission service cell). This is the LTE carrier aggregation technology (CA). Currently, it is limited to the aggregation of authorized carriers. The terminal supports the aggregation of five authorized carriers, that is, the maximum aggregate bandwidth is 5x 20M=100M.
由于LTE***授权频段内的授权载波资源相对匮乏(需要多家运营商去竞标购买),且宏基站(Macro eNB)下宏小区同构部署组网已经不能满足日益增加的LTE用户大业务流量的需求,因此LTE运营商希望开发和利用非授权频段内的非授权载波(Unlicensed Carrier)资源(不需要运营商去竞标购买,多个运营商可以自由地竞争抢占和使用),并且采用微基站(Micro eNB)或者低功率基站节点(LPN,Low Power Node)下的微小区异构部署组网来进行业务热点的覆盖,比如人口流量密集的区域。 The licensed carrier resources in the licensed band of the LTE system are relatively scarce (requires multiple operators to bid for purchase), and the macro-cell homogeneous configuration network of the macro base station (Macro eNB) cannot meet the increasing traffic of LTE users. Demand, therefore, LTE operators want to develop and utilize unlicensed carrier resources in unlicensed bands (no need for operators to bid for purchases, multiple operators can freely compete for preemption and use), and use micro base stations ( A micro-area heterogeneous deployment network in a micro-eNB or a low-power base station (LPN) to cover service hotspots, such as a densely populated area.
图2(a)为相关技术中LTE授权载波聚合的示意图。在图2(a)的示意图中,两个上下行无线覆盖大致相同,分别处于同授权频段内两个相邻的不同授权载波上的宏小区配置成CA操作的示意图,UE在有效覆盖范围内,能同时和两个授权载波上的宏小区进行上下行通讯,实现双授权载波上的数据收发。图2(b)为相关技术中LTE授权载波聚合的示意图,其是在图2(a)的基础之上,又增加了两个LPN微小区,它们分别处于非授权频段内两个不同的非授权载波上,且通过地面光纤协同和2(a)中的两个宏小区保持时序关系的同步;两个授权载波上的宏小区+两个非授权载波上的微小区,理论上也能共同配置成CA的操作,UE在其有效覆盖范围内,能同时和两个授权载波上的宏小区+两个非授权载波上的微小区进行上下行通讯,实现多载波上的数据收发。FIG. 2(a) is a schematic diagram of LTE authorized carrier aggregation in the related art. In the schematic diagram of FIG. 2(a), the two uplink and downlink radio coverages are substantially the same, and the macro cells on two adjacent different licensed carriers in the same licensed frequency band are respectively configured as CA operations, and the UE is within the effective coverage. The uplink and downlink communication can be performed simultaneously with the macro cell on the two authorized carriers to implement data transmission and reception on the dual authorized carrier. FIG. 2(b) is a schematic diagram of LTE-authorized carrier aggregation in the related art. On the basis of FIG. 2(a), two LPN micro-cells are added, which are respectively in two unlicensed frequency bands. On the authorized carrier, and through the terrestrial fiber coordination and the two macro cells in 2(a) to maintain the synchronization of the timing relationship; the macro cells on the two authorized carriers + the micro cells on the two unlicensed carriers can theoretically also be common In the operation of the CA, the UE can simultaneously perform uplink and downlink communication with the macro cell on the two authorized carriers and the micro cells on the two unlicensed carriers within the effective coverage of the UE to implement data transmission and reception on multiple carriers.
图3为相关技术中LTE纯授权载波聚合的工作架构图;在图3所示架构中,在eNB或者UE作为发送端的时候,MAC协议实体中配置有N个并行的HARQ(Hybrid Automatic Repeat reQuest,混合自动重传请求)实体,在特定TTI(Transmission Time Interval,传输时间间隔)(即eNB调度上下行数据块的TTI)下产生的N个HARQ数据包(或称为MAC PDU),经过物理层PHY实体的一系列相关处理(例如:信道编码,调制,资源块适配映射等),最后转化为LTE特定的物理波形信号,在N个授权载波上发送出去;作为接收端的UE或者eNB通过MAC和PHY实体进行相反的处理。这里唯一的主服务小区Pcell和N-1个辅服务小区Scell都是配置在授权载波之上的。3 is a working architecture diagram of LTE purely licensed carrier aggregation in the related art; in the architecture shown in FIG. 3, when the eNB or the UE is acting as a sender, N parallel HARQs (Hybrid Automatic Repeat reQuests) are configured in the MAC protocol entity. The hybrid automatic repeat request (eNB), the N-th HARQ data packet (or MAC PDU) generated under a specific TTI (Transmission Time Interval) (ie, the TTI of the eNB scheduling uplink and downlink data blocks) passes through the physical layer. A series of related processing of the PHY entity (eg, channel coding, modulation, resource block adaptation mapping, etc.), and finally converted into LTE specific physical waveform signals, which are transmitted on N authorized carriers; the UE or eNB as the receiving end passes the MAC The opposite is done with the PHY entity. Here, the only primary serving cell Pcell and N-1 secondary serving cells Scell are configured on the authorized carrier.
图4为相关技术中LTE非授权载波聚合的工作架构图。在图4所示架构中,在eNB或者UE作为发送端的时候,MAC协议实体中配置有N个并行的HARQ实体,但是其中一个或多个是服务授权载波的传统HARQ实体(同附图3中的HARQ实体),而其余是服务非授权载波的U-HARQ实体(需要对传统HARQ实体针对非授权载波的特性进行改造和增强);产生的N个HARQ数据包(或者MAC PDU),经过物理层PHY实体的一系列相关处理(例如:信道编码,调制,资源块适配映射等),最后转化为LTE特定的物理波形信号,其中一部分是在授权载波上发送出去的,而另外一部分是在非授权载波上发送出去的,同样这里也做了PHY和U-PHY实体的区分,以标 识和传统PHY实体的不同。这里仍然有唯一的授权载波上的主服务小区Pcell和多个授权载波上的辅服务小区Scell,而同时还有多个非授权载波上的辅服务小区U-Scell。FIG. 4 is a working architecture diagram of LTE unlicensed carrier aggregation in the related art. In the architecture shown in FIG. 4, when the eNB or the UE is the transmitting end, there are N parallel HARQ entities configured in the MAC protocol entity, but one or more of them are traditional HARQ entities that serve the licensed carrier (as in FIG. 3). The HARQ entity), and the rest are U-HARQ entities serving unlicensed carriers (requires modification and enhancement of the characteristics of the unlicensed carrier for the legacy HARQ entity); the generated N HARQ packets (or MAC PDUs), through the physics A series of correlation processing of the layer PHY entity (eg, channel coding, modulation, resource block adaptation mapping, etc.), and finally converted to LTE specific physical waveform signals, some of which are sent on the licensed carrier, and the other part is The non-authorized carrier is sent out, and the PHY and U-PHY entities are also distinguished here. The difference between the knowledge and the traditional PHY entity. There is still a primary serving cell Pcell on the unique authorized carrier and a secondary serving cell Scell on the plurality of authorized carriers, and at the same time a secondary serving cell U-Scell on the plurality of unlicensed carriers.
由于在一个物理局部区域,非授权载波上的资源被多个同运营商和/或异运营商的多个eNBs和/或WIFI AP节点所共享,因此每个eNB都要通过LBT(Listen Before Talk,先听后讲)的方式来先监听检测信道的忙闲,再尝试抢占非授权载波上的信道资源。比如:在同一片服务区域,运营商A的eNB1为自己的用户UE1配置了CA:Pcell1+U-Scell;运营商B的eNB2为自己的用户UE2配置了CA:Pcell2+U-Scell;Pcell1和Pcell2分别处于运营商A和B自己的授权载波上,彼此之间没有干扰冲突和信道资源共享的问题;但是U-Scell却处于相同的非授权载波上,此时每当运营商A和/或B的eNB想在U-Scell上发送数据,必须要先监听检测该非授权载波是否被其它节点(eNB、WIFI AP、UE等)所占用。比如eNB1在一个周期时刻执行CCA(Clear Channel Assessment)检测出来的该非授权载波全带宽上的接收能量大于一门限,则表示此时它已经被占用,eNB1此刻不能再去抢占该非授权载波上的信道资源。之后通常eNB1在时间上回退一段时间,等下一个周期时刻,再执行下一轮的CCA检测,以尝试抢占该非授权载波上的资源。Since the resources on the unlicensed carrier are shared by multiple eNBs and/or WIFI AP nodes of the same carrier and/or different operators in one physical local area, each eNB must pass LBT (Listen Before Talk). The method of listening to the latter is to listen to the busy channel of the detection channel first, and then try to preempt the channel resources on the unlicensed carrier. For example, in the same service area, eNB1 of operator A configures CA:Pcell1+U-Scell for its own user UE1; eNB2 of operator B configures CA:Pcell2+U-Scell for its own user UE2; Pcell1 and Pcell2 is on the carrier's own authorized carriers, and there is no interference collision and channel resource sharing between them; but the U-Scell is on the same unlicensed carrier. At this time, whenever the operator A and/or The eNB of B wants to send data on the U-Scell, and must first listen to detect whether the unlicensed carrier is occupied by other nodes (eNB, WIFI AP, UE, etc.). For example, when the received energy of the unlicensed carrier detected by the CCA (Clear Channel Assessment) is greater than a threshold, the eNB1 indicates that it has been occupied at this time, and the eNB1 cannot reoccupy the unlicensed carrier at this moment. Channel resources. Then, usually, eNB1 rolls back time for a period of time, waits for the next cycle time, and then performs the next round of CCA detection to try to preempt the resources on the unlicensed carrier.
因此,在同一非授权载波频点上,如何充分利用多个源发于不同物理位置上eNB节点的服务U-Scell的资源是亟待解决的问题。该问题对于同一授权载波频点上的场景也普遍适用。Therefore, how to fully utilize the resources of the service U-Scell of the eNB node originating from different physical locations on the same unlicensed carrier frequency point is an urgent problem to be solved. This problem is also generally applicable to scenarios on the same licensed carrier frequency.

下面对本发明实施例提供的方法进行说明:The method provided by the embodiment of the present invention is described below:
eNB和UE都具备对非授权载波进行CA的能力。eNB通过前期对目标非授权频段的广泛扫描和监听检测,能给出自己服务的特定UE(即满足一定无线环境条件的UE,下同)一种LTE有非授权载波聚合的配置,即至少有一个授权载波上的Pcell和一个或N个的非授权载波小区U-Scell(i,j),其中i为非授权载波的索引号,j为在第i个非授权载波上配置的服务小区索引号。根据LTE中CA技术的配置限制,j只能为1,表示在第i个非授权载波上只能配置有唯一个U-Scell。根据上述实施例内容,j可以取值[1,2,3…M],表示在第i个非授权载波上最大能配置有M个U-Scell。这M个U-Scell的PCI(Physical-layer Cell Identity,小区物理标识)和ECGI(E-UTRAN Cell Global Identifier,小区全球标识)可以相同,也可以不同。M个U-Scell的标识(PCI和ECGI)相同表示这M个U-Scell从高层RRC协议看来属于同一个服务小区,每个U-Scell只是该服务小区协同下的其中一个信号发射和接收点(TP,Transmission Point);M个U-Scell的标识(PCI和ECGI)不同表示这M个U-Scell从高层RRC协议看来属于多个独立的服务小区,需要RRC进行独立地配置,每个U-Scell都能独立地进行信号发射和接收,即,使用同一非授权载波的资源的至少两个辅服务小区的标识不同,这将是本文后续详细介绍的内容,同理,使用同一授权载波的资源的至少两个辅服务小区的标识不同。其中,所述辅服务小区的标识为小区物理标识PCI和小区全球标识ECGI。Both the eNB and the UE have the capability to perform CA on unlicensed carriers. The eNB can provide a specific UE for its own service (that is, a UE that satisfies a certain radio environment condition, the same below) through the extensive scanning and monitoring detection of the target unlicensed frequency band in the previous stage, and the LTE has an unlicensed carrier aggregation configuration, that is, at least a Pcell on an authorized carrier and one or N unlicensed carrier cells U-Scell(i,j), where i is the index number of the unlicensed carrier, and j is the serving cell index configured on the ith unlicensed carrier number. According to the configuration limitation of the CA technology in LTE, j can only be 1, indicating that only a single U-Scell can be configured on the i-th unlicensed carrier. According to the above embodiment, j can take the value [1, 2, 3...M], indicating that M U-Scells can be configured on the i-th unlicensed carrier. The PCI (Physical-layer Cell Identity) and the ECGI (E-UTRAN Cell Global Identifier) of the M U-Scells may be the same or different. The identifiers of the M U-Scells (PCI and ECGI) are the same, indicating that the M U-Scells belong to the same serving cell from the high-layer RRC protocol, and each U-Scell is only one of the signals transmitted and received by the serving cell. Point (TP, Transmission Point); M U-Scell identifiers (PCI and ECGI) differently indicate that the M U-Scells belong to multiple independent serving cells from the high-layer RRC protocol, and need to be independently configured by RRC. Each U-Scell can independently transmit and receive signals, that is, the identifiers of at least two secondary serving cells using the same unlicensed carrier are different, which will be described in detail later in this document. Similarly, the same authorization is used. The identifiers of at least two secondary serving cells of the resources of the carrier are different. The identifier of the secondary serving cell is a cell physical identifier PCI and a cell global identifier ECGI.
所述演进基站获取所述终端所处的非授权微小区的信息;Obtaining, by the evolved base station, information about an unauthorized micro cell where the terminal is located;
所述演进基站根据所述非授权或者授权微小区的配置帧格式,为所述终端选择辅服务小区。The evolved base station selects a secondary serving cell for the terminal according to the configured frame format of the unlicensed or authorized micro cell.
由于配置帧格式有两种不同的情况,下面针对两种情况进行分别说明:Since there are two different situations in the configuration frame format, the following two cases are described separately:
1:U-Scell是个纯下行的帧格式小区,即U-SDL(Unlicensed-Supplementary Downlink,非授权载波充当补充下行传输资源)情况;2:U-Scell是个有上下 行的帧格式小区,即U-UL/DL(Unlicensed-Uplink Downlink,非授权载波充当上行和下行传输资源)情况。其中:1: U-Scell is a pure downlink frame format cell, that is, U-SDL (Unlicensed-Supplementary Downlink, unlicensed carrier acts as supplementary downlink transmission resource); 2: U-Scell is up and down A frame format cell of a row, that is, a U-UL/DL (Unlicensed-Uplink Downlink, an unlicensed carrier serving as an uplink and downlink transmission resource). among them:
1:U-SDL配置情况:1: U-SDL configuration:
S1:对于特定UE,通过在第i个非授权载波上的RRM(Radio Resource Management,无线资源管理)导频测量,发现自己同时处于周边多个LTE非授权微小区的信号覆盖之下。通过读取这些非授权微小区的***广播消息,获悉了它们的小区物理标识PCI和小区全球标识ECGI;S1: For a specific UE, by using RRM (Radio Resource Management) pilot measurement on the i-th unlicensed carrier, it is found that it is simultaneously under the signal coverage of multiple LTE unlicensed micro cells in the periphery. By reading the system broadcast messages of these unauthorized micro cells, they are informed of their cell physical identity PCI and cell global identity ECGI;
S2:UE向演进基站eNB发送终端所处的非授权或者授权微小区集合的标识信息;其中,UE通过授权载波上的宏小区信令无线承载(SRB,Signaling Radio Bearer)发送RRC消息把这些发现的非授权微小区上报给eNB;S2: The UE sends the identifier information of the unlicensed or authorized micro cell set in which the terminal is located to the evolved base station eNB. The UE sends the RRC message by using the macro cell signaling radio bearer (SRB) on the authorized carrier to send the RRC message. The unlicensed micro cell is reported to the eNB;
S3:eNB通过对这些非授权微小区PCI和ECGI的检索和内部分析,发现其中,多个U-Scell(i,j)服务小区都属于当前宏小区的同一eNB下,且都处于U-SDL配置模式,因此它们的下行时序都相同,满足配置下行CA的基本条件;S3: The eNB finds that the multiple U-Scell (i, j) serving cells belong to the same eNB of the current macro cell by searching and internal analysis of the unlicensed micro cell PCI and ECGI, and both are in U-SDL. Configuration mode, so their downlink timing is the same, meeting the basic conditions for configuring the downlink CA;
S4:eNB采用LTE技术:RRC配置流程对UE进行有非授权载波的CA配置:Pcell+多个U-Scell(i,j);S4: The eNB adopts the LTE technology: the RRC configuration procedure performs the CA configuration of the unlicensed carrier on the UE: Pcell+multiple U-Scell(i,j);
S5:eNB按照和多个U-Scell(i,j)处于不同载波频点相同的方式,进行MAC协议层相关处理,如多个下行并行的HARQ进程管理,多个并行的MAC PDU发送准备等,分别通过理想回传链路(Ideal Backhaul如光纤)发送给多个U-Scell(i,j)服务节点,然后在授权宏小区Pcell上进行PDCCH跨载波下行调度;S5: The eNB performs MAC protocol layer related processing in the same manner as multiple U-Scells (i, j) are in different carrier frequency points, such as multiple downlink parallel HARQ process management, multiple parallel MAC PDU transmission preparation, and the like. And transmitting to the plurality of U-Scell (i, j) serving nodes through an ideal backhaul link (Ideal Backhaul, for example, optical fiber), and then performing PDCCH cross-carrier downlink scheduling on the authorized macro cell Pcell;
S6:多个U-Scell(i,j)服务节点根据LBE(Load Based Equipment)或者FBE(Frame Based Equipment)的规则和要求,在一个特定时刻(即根据CCA算法,需要做CCA检测的时刻,下同)进行下行CCA检测,尝试占用整个非授权载波信道;如果下行CCA检测的能量低于预设门限,表示该信道空闲,多个U-Scell(i,j)服务节点就可以分别利用自己抢占到的非授权载波资源进行PDSCH数据块的发送。如果CCA检测失败,则该服务节点就不能利用相应的U-Scell(i,j)资源进行PDSCH数据块的发送。因此UE可以独立地从多个 U-Scell(i,j)接收PDSCH数据块,但是实际不能同时从多个U-Scell(i,j)同时接收多个PDSCH数据块,通过U-Scell(i,j)发送节点的CCA检测和抢占,导致数据块的发送和接收时间上是错开的,以时分方式进行;S6: a plurality of U-Scell (i, j) service nodes are required to perform CCA detection according to the rules and requirements of LBE (Load Based Equipment) or FBE (Frame Based Equipment) at a specific time (ie, according to the CCA algorithm, The same downlink) performs downlink CCA detection, and attempts to occupy the entire unlicensed carrier channel; if the energy of the downlink CCA detection is lower than the preset threshold, indicating that the channel is idle, multiple U-Scell (i, j) service nodes can respectively utilize themselves The preempted unlicensed carrier resources are used to transmit PDSCH data blocks. If the CCA detection fails, the serving node cannot use the corresponding U-Scell (i, j) resource to transmit the PDSCH data block. So the UE can independently from multiple The U-Scell(i,j) receives the PDSCH data block, but cannot actually receive multiple PDSCH data blocks simultaneously from multiple U-Scells (i, j), and transmits the CCA detection of the transmitting node through the U-Scell (i, j). And preemption, causing the transmission and reception time of the data block to be staggered, in a time division manner;
S7:UE按照和多个U-Scell(i,j)处于不同载波频点相同的方式,进行MAC协议层相关处理,下行MAC PDU接收和重排序,下行HARQ进程反馈,根据接收的结果,在授权宏小区Pcell上进行PUCCH上行反馈。S7: The UE performs MAC protocol layer correlation processing, downlink MAC PDU reception and reordering, and downlink HARQ process feedback according to the same manner that multiple U-Scells (i, j) are in different carrier frequency points, according to the received result, The PUCCH uplink feedback is performed on the authorized macro cell Pcell.
上述流程的总体工作方式和U-Scell(i,j)处于不同的载波频点类似,但是区别就在于U-Scell(i,j)实际可以配置处于同一非授权载波频点,这样UE可以在一个非授权载波频点上和多个U-Scell(i,j)建立多条无线链接Radio Link,最大程度聚合利用周边的非授权载波资源,这样可以避免U-Scell(i,j)服务节点因为经历它所在局部区域的CCA检测失败,而无法及时下行发送PDSCH数据块,从而对下行数据传输率有负面影响的问题。The overall working mode of the above process is similar to that of the U-Scell (i, j) at different carrier frequencies, but the difference is that the U-Scell (i, j) can actually be configured at the same unlicensed carrier frequency, so that the UE can Multiple unlicensed carrier frequencies and multiple U-Scells (i, j) establish multiple radio links, which maximize the aggregation of the surrounding unlicensed carrier resources, thus avoiding U-Scell (i, j) service nodes. Because the CCA detection of the local area in which it is located fails, the PDSCH data block cannot be sent in the downlink in time, which has a negative impact on the downlink data transmission rate.
上述内容理论上同样可以适用于授权载波的情况下,即Scell(i,j)可以配置处于同一授权载波频点,这样UE可以在一个授权载波频点上和多个Scell(i,j)建立多条无线链接。但是对于授权载波,由于多个Scell(i,j)服务节点在下行发送不同的PDSCH数据块之前,不会做CCA下行检测,因此如果多个Scell(i,j)同时在一个TTI下行调度了PDSCH数据块,则UE侧会产生接收冲突,无法正确接收解调;如果多个Scell(i,j)不同时在一个TTI下行调度了PDSCH数据块,则可以通过优化单节点调度或者下行多点协作技术(COMP,Coordinated Multiple Point Transmission)获得更好的增益。而对于非授权载波,由于多个U-Scell(i,j)服务节点在下行发送数据块之前,总会做CCA下行检测,因此U-Scell(i,j)同时在一个TTI下行调度了PDSCH数据块的概率很低,则UE侧产生的接收冲突概率也较低,从而正确接收解调概率较高。由于单节点存在抢占和使用非授权载波资源短时性和公平性的限制,因此无法有效通过优化单节点调度或者下行多点协作技术来获得增益,因此本发明实施例的应用价值更大。The above content can also be applied to the authorized carrier in theory, that is, Scell(i, j) can be configured to be at the same authorized carrier frequency, so that the UE can establish a plurality of Scells (i, j) at one authorized carrier frequency. Multiple wireless links. However, for the authorized carrier, since multiple Scell(i,j) serving nodes do not perform CCA downlink detection before transmitting different PDSCH data blocks in the downlink, if multiple Scells (i, j) are scheduled in one TTI downlink at the same time, In the PDSCH data block, the UE side generates a reception collision and cannot receive the demodulation correctly. If multiple Scells (i, j) are different, the PDSCH data block is scheduled in one TTI downlink, and then the single node scheduling or the downlink multipoint can be optimized. Coordinated Multiple Point Transmission (COMP) achieves better gain. For an unlicensed carrier, since multiple U-Scell (i, j) serving nodes always perform CCA downlink detection before transmitting data blocks in the downlink, U-Scell(i, j) simultaneously schedules PDSCH in one TTI downlink. The probability of the data block is very low, and the probability of receiving collision generated by the UE side is also low, so that the correct reception and demodulation probability is high. Because a single node has the limitation of preemption and use of unlicensed carrier resources for short-term and fairness, the gain cannot be effectively obtained by optimizing single-node scheduling or downlink multi-point cooperation technology. Therefore, the application value of the embodiment of the present invention is greater.
2:U-UL/DL配置情况。2: U-UL/DL configuration.
DL的方式方法同上面情况1,只是eNB做下行CCA检测和资源抢占受限在DL子帧的位置;UL对应UE做上行CCA检测和资源抢占,只是受限在 UL子帧的位置,下面将详细描述:The DL mode is the same as the above case 1, except that the eNB performs downlink CCA detection and resource preemption is limited in the location of the DL subframe; the UL corresponding UE performs uplink CCA detection and resource preemption, but is limited in The location of the UL subframe, which will be described in detail below:
S1:对于特定UE,通过在第i个非授权载波上的RRM导频测量,发现自己同时处于周边多个LTE非授权微小区的信号覆盖之下。通过读取这些非授权微小区的***广播消息,获悉了它们的PCI和ECGI;S1: For a specific UE, by RRM pilot measurement on the i-th unlicensed carrier, it is found that it is under the signal coverage of multiple LTE unlicensed micro cells in the periphery. Obtain their PCI and ECGI by reading the system broadcast messages of these unauthorized micro cells;
S2:UE通过授权载波上的宏小区信令无线承载(SRB,Signaling Radio Bearer)发送RRC消息把这些发现的非授权微小区上报给eNB;S2: The UE sends an RRC message to the eNB by sending an RRC message to the eNB by using an RRC message on the radio bearer (SRB, Signaling Radio Bearer).
S3:eNB通过对这些非授权微小区PCI和ECGI的检索和内部分析,发现其中多个U-Scell(i,j)服务小区都属于当前宏小区的同一eNB下,且都处于U-UL/DL配置模式,因此它们的上下行时序都相同,满足配置上下行CA的基本条件;S3: The eNB finds that multiple U-Scell (i, j) serving cells belong to the same eNB of the current macro cell by searching and internal analysis of these unlicensed micro cells PCI and ECGI, and all are in U-UL/ DL configuration mode, so their uplink and downlink timings are the same, meeting the basic conditions for configuring the uplink and downlink CA;
S4:eNB采用LTE技术:RRC配置流程对UE进行有非授权载波的CA配置:Pcell+多个U-Scell(i,j);S4: The eNB adopts the LTE technology: the RRC configuration procedure performs the CA configuration of the unlicensed carrier on the UE: Pcell+multiple U-Scell(i,j);
S5:eNB按照和多个U-Scell(i,j)处于不同载波频点相同的方式,进行MAC协议层相关处理,如多个上下行并行的HARQ进程管理,多个并行的MAC PDU发送准备等,分别通过理想回传链路(Ideal Backhaul如光纤)发送给多个U-Scell(i,j)服务节点,然后在授权宏小区Pcell上进行PDCCH跨载波下行调度。因为UE还需要在非授权载波资源做上行数据的传输,因此eNB还需要在授权宏小区Pcell上进行PDCCH跨载波上行调度。S5: The eNB performs MAC protocol layer correlation processing in the same manner as multiple U-Scells (i, j) are in different carrier frequency points, such as multiple uplink and downlink parallel HARQ process management, and multiple parallel MAC PDU transmission preparations. Etc., respectively, is sent to multiple U-Scell (i, j) serving nodes through an ideal backhaul link (Ideal Backhaul, such as optical fiber), and then PDCCH cross-carrier downlink scheduling is performed on the authorized macro cell Pcell. Because the UE also needs to perform uplink data transmission on the unlicensed carrier resources, the eNB also needs to perform PDCCH cross-carrier uplink scheduling on the authorized macro cell Pcell.
S6:多个U-Scell(i,j)服务节点根据LBE(Load Based Equipment)或者FBE(Frame Based Equipment)的规则和要求,在一个特定时刻进行下行CCA检测,尝试占用整个非授权载波信道;如果下行CCA检测的能量低于预设门限,表示该信道空闲,多个U-Scell(i,j)服务节点就可以分别利用自己抢占到的非授权载波资源进行PDSCH数据块的发送。如果CCA检测失败,则该服务节点就不能利用相应的U-Scell(i,j)资源进行PDSCH数据块的发送。因此UE可以独立地从多个U-Scell(i,j)接收PDSCH数据块,但是实际不能同时从多个U-Scell(i,j)同时接收多个PDSCH数据块,通过U-Scell(i,j)发送节点的CCA检测和抢占,导致发送和接收时间上是错开的。对于上行,单个UE根据LBE(Load Based Equipment)或者FBE(Frame Based Equipment)的规则和要求,在一个特定时刻进行上行CCA检测,尝试占用整个非授权载波信道;如 果上行CCA检测的能量低于预设门限,表示该信道空闲,单个UE就可以抢占和利用到非授权载波资源进行PUSCH数据块的发送,eNB可以通过多个U-Scell(i,j)服务节点接收上行数据块,形成接收分集。如果上行CCA检测失败,该UE就暂时不能进行PUSCH数据块的发送,时间上回退等待下个抢占时机;S6: The plurality of U-Scell (i, j) service nodes perform downlink CCA detection at a specific moment according to rules and requirements of LBE (Load Based Equipment) or FBE (Frame Based Equipment), and try to occupy the entire unlicensed carrier channel; If the energy of the downlink CCA detection is lower than the preset threshold, indicating that the channel is idle, the multiple U-Scell (i, j) serving nodes may separately transmit the PDSCH data block by using the pre-emptied unlicensed carrier resources. If the CCA detection fails, the serving node cannot use the corresponding U-Scell (i, j) resource to transmit the PDSCH data block. Therefore, the UE can independently receive PDSCH data blocks from multiple U-Scells (i, j), but can not simultaneously receive multiple PDSCH data blocks from multiple U-Scells (i, j) simultaneously, through U-Scell (i , j) The CCA detection and preemption of the transmitting node causes the transmission and reception time to be staggered. For the uplink, a single UE performs uplink CCA detection at a specific time according to the rules and requirements of the LBE (Load Based Equipment) or FBE (Frame Based Equipment), and attempts to occupy the entire unlicensed carrier channel; If the energy of the uplink CCA detection is lower than the preset threshold, indicating that the channel is idle, a single UE can preempt and utilize the unlicensed carrier resources to transmit the PUSCH data block, and the eNB can serve through multiple U-Scells (i, j). The node receives the uplink data block to form a receive diversity. If the uplink CCA detection fails, the UE temporarily cannot transmit the PUSCH data block, and the time retreats to wait for the next preemption opportunity;
S7:UE按照和多个U-Scell(i,j)处于不同载波频点相同的方式,进行MAC协议层相关处理,下行MAC PDU接收和重排序,下行HARQ进程反馈,根据接收的结果,在授权宏小区Pcell上进行PUCCH上行反馈。U-Scell(i,j)服务节点把接收到的PUSCH数据块通过理想回传链路发回给eNB,eNB只要能从一个U-Scell(i,j)服务节点上正确接收到PUSCH数据块,就通过授权宏小区Pcell进行PHICH下行确认反馈,如果eNB无法从任何一个U-Scell(i,j)服务节点上正确接收到PUSCH数据块,则要求UE重传PUSCH数据块。S7: The UE performs MAC protocol layer correlation processing, downlink MAC PDU reception and reordering, and downlink HARQ process feedback according to the same manner that multiple U-Scells (i, j) are in different carrier frequency points, according to the received result, The PUCCH uplink feedback is performed on the authorized macro cell Pcell. The U-Scell (i, j) serving node sends the received PUSCH data block back to the eNB through the ideal backhaul link, and the eNB can correctly receive the PUSCH data block from a U-Scell (i, j) serving node. The PHICH downlink acknowledgement feedback is performed by authorizing the macro cell Pcell. If the eNB cannot correctly receive the PUSCH data block from any one of the U-Scell (i, j) serving nodes, the UE is required to retransmit the PUSCH data block.

图7为本发明应用示例一提供的运营商A一授权载波宏小区A下非授权载波微小区的部署示意图。图7所示示意图中eNB通过前期对目标非授权频段5150MHz-5350MHz的广泛扫描和监听检测,决定后续CA的工作频段范围为:5160MHz-5170MHz的10M U-Scell(i,j)带宽。FIG. 7 is a schematic diagram of deployment of an unlicensed carrier micro cell in an A-licensed carrier macro cell A according to an application example 1 of the present invention. In the schematic diagram shown in FIG. 7, the eNB determines the operating frequency range of the subsequent CA to be 10M U-Scell(i,j) bandwidth of 5160MHz-5170MHz through extensive scanning and monitoring detection of the target unlicensed frequency band 5150MHz-5350MHz.
S101:对于特定UE,通过在5160MHz-5170MHz非授权载波上的RRM导频测量,发现自己同时处于周边多个LTE非授权微小区的信号覆盖之下。通过读取这些非授权微小区的***广播消息,获悉了它们的PCI和ECGI;S101: For a specific UE, by RRM pilot measurement on an unlicensed carrier of 5160 MHz-5170 MHz, it is found that it is simultaneously under the signal coverage of multiple LTE unlicensed micro cells in the periphery. Obtain their PCI and ECGI by reading the system broadcast messages of these unauthorized micro cells;
S102:UE通过授权载波上的宏小区信令无线承载(SRB,Signaling Radio Bearer)发送Measurement Report消息把这些发现的非授权微小区上报给eNB;S102: The UE sends a Measurement Report message to the eNB by sending a Measurement Report message by using a Signaling Radio Bearer (SRB) on the authorized carrier.
S103:eNB通过对这些非授权微小区PCI和ECGI的检索和内部分析,发现其中3个U-Scell(i,1),U-Scell(i,2),U-Scell(i,3)服务小区都属于当前宏小区的同一eNB下,且都处于U-SDL配置模式,因此它们的下行时序都相同,满足配置下行CA的基本条件;S103: The eNB finds three U-Scell(i,1), U-Scell(i,2), U-Scell(i,3) services by searching and internal analysis of these unlicensed microcells PCI and ECGI. The cells belong to the same eNB of the current macro cell, and are all in the U-SDL configuration mode. Therefore, their downlink timings are the same, and the basic conditions for configuring the downlink CA are met.
S104:eNB采用LTE技术:RRC配置流程对UE进行有非授权载波的 CA配置:Pcell+U-Scell(i,1)+U-Scell(i,2)+U-Scell(i,3);S104: The eNB adopts an LTE technology: an RRC configuration procedure is performed on the UE with an unlicensed carrier. CA configuration: Pcell+U-Scell(i,1)+U-Scell(i,2)+U-Scell(i,3);
S105:eNB按照和3个U-Scell(i,1),U-Scell(i,2),U-Scell(i,3)处于不同载波频点相同的方式,进行MAC协议层相关处理,如多个下行并行的HARQ进程管理,多个并行的MAC PDU发送准备等,分别通过理想回传链路(Ideal Backhaul如光纤)发送给U-Scell(i,1),U-Scell(i,2),U-Scell(i,3)服务节点,然后在授权宏小区Pcell上进行PDCCH跨载波下行调度;S105: The eNB performs MAC protocol layer correlation processing according to the manner that the three U-Scells (i, 1), U-Scells (i, 2), and U-Scells (i, 3) are in different carrier frequency points, such as Multiple downlink parallel HARQ process management, multiple parallel MAC PDU transmission preparation, etc., respectively sent to U-Scell (i, 1), U-Scell (i, 2) through an ideal backhaul link (Ideal Backhaul such as optical fiber) a U-Scell (i, 3) serving node, and then performing PDCCH cross-carrier downlink scheduling on the authorized macro cell Pcell;
S106:U-Scell(i,1),U-Scell(i,2),U-Scell(i,3)服务节点根据FBE的规则和要求,在一个特定时刻进行下行CCA检测,尝试占用整个5160MHz-5170MHz非授权载波信道;如果下行CCA检测的能量低于预设门限,表示该信道空闲,U-Scell(i,1),U-Scell(i,2),U-Scell(i,3)服务节点就可以分别利用自己抢占到的非授权载波资源进行PDSCH数据块的发送。如果CCA检测失败,则该服务节点就不能利用相应的资源进行PDSCH数据块的发送。UE独立地从U-Scell(i,1),U-Scell(i,2),U-Scell(i,3)接收PDSCH数据块,但是实际不能同时接收多个PDSCH数据块;S106: U-Scell(i,1), U-Scell(i,2), U-Scell(i,3) The serving node performs downlink CCA detection at a specific moment according to the rules and requirements of the FBE, and attempts to occupy the entire 5160 MHz. -5170MHz unlicensed carrier channel; if the energy of downlink CCA detection is lower than the preset threshold, it indicates that the channel is idle, U-Scell(i,1), U-Scell(i,2), U-Scell(i,3) The serving node can separately transmit the PDSCH data block by using the unlicensed carrier resources that it preempts. If the CCA detection fails, the serving node cannot use the corresponding resources to transmit the PDSCH data block. The UE independently receives the PDSCH data block from the U-Scell (i, 1), U-Scell (i, 2), U-Scell (i, 3), but cannot actually receive multiple PDSCH data blocks at the same time;
S107:UE按照和U-Scell(i,1),U-Scell(i,2),U-Scell(i,3)处于不同载波频点相同的方式,进行MAC协议层相关处理,下行MAC PDU接收和重排序,下行HARQ进程反馈,根据接收的结果,在授权宏小区Pcell上进行PUCCH上行反馈。S107: The UE performs MAC protocol layer correlation processing and downlink MAC PDU according to the same manner that U-Scell (i, 1), U-Scell (i, 2), and U-Scell (i, 3) are in different carrier frequency points. Receiving and reordering, downlink HARQ process feedback, and performing PUCCH uplink feedback on the authorized macro cell Pcell according to the received result.
对于LTE Rel-10版本之后纯授权载波的聚合。有此配置约束:UE在每个授权载波上只能配置有一个服务小区(唯一的小区物理标识PCI,Physical Cell Identity和全球标识ECGI,E-UTRA Cell Global Identity),而Pcell和Scell(s)的维护更新则通过LTE***无线资源管理(RRM,Radio Resource Management)和RRC连接重配机制完成的。比如用一个无线质量覆盖更好和/或小区负荷更轻的目标Pcell_new或Scell_new去替换当前无线质量覆盖较差和/或小区负荷较重的源Pcell_old或Scell_old,但在同一时刻每个授权载波上只能配置有一个Pcell或Scell,这种维护更新对LTE网络***容量和终端的业务体验都有益处。和LTE纯授权载波聚合的场景不同,有LTE非授权载波聚合的情况下,每个非授权载波上的U-Scell(i)对于特定UE,它的资源存在和可使用性是不确定的,即使UE在一个非授权载波上配置了一个U-Scell(i), 不是任何时刻它就一定能抢占到和利用到非授权载波资源的,因为这还依赖于该eNB节点和UE周边复杂的无线干扰环境。如果有LTE非授权载波聚合的情况依旧沿用纯授权载波聚合的配置约束,则可能导致U-Scell(i)的资源使用效率比授权Scell(i)要差,从而UE不能从CA技术中充分获得数据速率增益。Aggregation of purely licensed carriers after the LTE Rel-10 release. There is this configuration constraint: the UE can only be configured with one serving cell (the unique cell physical identifier PCI, Physical Cell Identity and E-UTRA Cell Global Identity), and Pcell and Scell(s) on each authorized carrier. The maintenance update is completed by the LTE system Radio Resource Management (RRM) and the RRC connection reconfiguration mechanism. For example, a target Pcell_new or Scell_new with better radio quality coverage and/or lighter cell load is used to replace the source Pcell_old or Scell_old with poor current radio quality coverage and/or cell load, but at the same time on each authorized carrier. Only one Pcell or Scell can be configured. This maintenance update is beneficial to the LTE network system capacity and the service experience of the terminal. Different from the scenario of LTE purely licensed carrier aggregation, in the case of LTE unlicensed carrier aggregation, the U-Scell(i) on each unlicensed carrier is uncertain for its resource existence and usability for a specific UE. Even if the UE is configured with a U-Scell(i) on an unlicensed carrier, It is not always possible to preempt and utilize unlicensed carrier resources, since this also depends on the complex wireless interference environment around the eNB node and the UE. If the LTE unlicensed carrier aggregation still uses the configuration constraints of purely authorized carrier aggregation, the resource usage efficiency of the U-Scell(i) may be worse than that of the authorized Scell(i), so that the UE cannot fully obtain the CA technology.

图8为本发明应用示例二提供的运营商B一授权载波宏小区B下非授权载波微小区的部署示意图。图7所示示意图中,eNB通过前期对目标非授权频段5150MHz-5350MHz的广泛扫描和监听检测,决定后续CA的工作频段范围为:5260MHz-5280MHz的20M U-Scell(i,j)带宽。FIG. 8 is a schematic diagram of deployment of an unlicensed carrier micro cell in an operator B-authorized carrier macro cell B according to application example 2 of the present invention. In the schematic diagram shown in FIG. 7, the eNB determines the operating frequency range of the subsequent CA to be 20M U-Scell(i,j) bandwidth of 5260MHz-5280MHz through extensive scanning and monitoring detection of the target unlicensed frequency band 5150MHz-5350MHz.
S201:对于特定UE,通过在5260MHz-5280MHz非授权载波上的RRM导频测量,发现自己同时处于周边多个LTE非授权微小区的信号覆盖之下。通过读取这些非授权微小区的***广播消息,获悉了它们的PCI和ECGI;S201: For a specific UE, by RRM pilot measurement on an unlicensed carrier of 5260 MHz-5280 MHz, it is found that it is simultaneously under the signal coverage of multiple LTE unlicensed micro cells in the periphery. Obtain their PCI and ECGI by reading the system broadcast messages of these unauthorized micro cells;
S202:UE通过授权载波上的宏小区信令无线承载(SRB,Signaling Radio Bearer)发送Measurement Report消息把这些发现的非授权微小区上报给eNB;S202: The UE sends the Measurement Report message to the eNB by sending a Measurement Report message by using a Signaling Radio Bearer (SRB) on the authorized carrier.
S203:eNB通过对这些非授权微小区PCI和ECGI的检索和内部分析,发现其中U-Scell(i,1),U-Scell(i,2)服务小区都属于当前宏小区的同一eNB下,且都处于U-UL/DL配置模式,因此它们的上下行时序都相同,满足配置上下行CA的基本条件;S203: The eNB finds that the U-Scell(i,1) and U-Scell(i,2) serving cells belong to the same eNB of the current macro cell by searching and internal analysis of the unlicensed microcells PCI and ECGI. Both are in the U-UL/DL configuration mode, so their uplink and downlink timings are the same, which satisfies the basic conditions for configuring the uplink and downlink CA;
S204:eNB采用LTE技术:RRC配置流程对UE进行有非授权载波的CA配置:Pcell+U-Scell(i,1)+U-Scell(i,2);S204: The eNB adopts the LTE technology: the RRC configuration procedure performs the CA configuration of the unlicensed carrier on the UE: Pcell+U-Scell(i,1)+U-Scell(i,2);
S205:eNB按照和U-Scell(i,1),U-Scell(i,2)处于不同载波频点相同的方式,进行MAC协议层相关处理,如多个上下行并行的HARQ进程管理,多个并行的MAC PDU发送准备等,分别通过理想回传链路(Ideal Backhaul如光纤)发送给U-Scell(i,1),U-Scell(i,2)服务节点,然后在授权宏小区Pcell上进行PDCCH跨载波下行调度。因为UE还需要在非授权载波资源做上行数据的传输,因此eNB还需要在授权宏小区Pcell上进行PDCCH跨载波上行调度; S205: The eNB performs MAC protocol layer related processing in the same manner as the U-Scell (i, 1) and the U-Scell (i, 2) are in different carrier frequency points, for example, multiple uplink and downlink parallel HARQ process management, and more Parallel MAC PDU transmission preparation, etc., respectively sent to the U-Scell (i, 1), U-Scell (i, 2) service node through an ideal backhaul link (Ideal Backhaul, such as optical fiber), and then in the authorized macro cell Pcell The PDCCH cross-carrier downlink scheduling is performed on the PDCCH. The eNB also needs to perform PDCCH cross-carrier uplink scheduling on the authorized macro cell Pcell because the UE also needs to perform uplink data transmission on the unlicensed carrier resource.
S206:U-Scell(i,1),U-Scell(i,2)服务节点根据FBE的规则和要求,在一个特定时刻进行下行CCA检测,尝试占用5260MHz-5280MHz非授权载波信道;如果下行CCA检测的能量低于预设门限,表示该信道空闲,U-Scell(i,1),U-Scell(i,2)服务节点就可以分别利用自己抢占到的非授权载波资源进行PDSCH数据块的发送。如果CCA检测失败,则该服务节点就不能利用相应的资源进行PDSCH数据块的发送。因此UE独立地从U-Scell(i,1),U-Scell(i,2)接收PDSCH数据块,但是不能同时接收多个PDSCH数据块。对于上行,单个UE根据FBE的规则和要求,在一个特定时刻进行上行CCA检测,尝试占用5260MHz-5280MHz非授权载波信道;如果上行CCA检测的能量低于预设门限,表示该信道空闲,单个UE就可以抢占和利用到非授权载波资源进行PUSCH数据块的发送,eNB可以通过U-Scell(i,1),U-Scell(i,2)服务节点接收,形成接收分集。如果上行CCA检测失败,该UE就暂时不能进行PUSCH数据块的发送,时间上回退等待下个抢占时机;S206: U-Scell (i, 1), the U-Scell (i, 2) serving node performs downlink CCA detection at a specific moment according to the rules and requirements of the FBE, and attempts to occupy an unlicensed carrier channel of 5260 MHz-5280 MHz; if the downlink CCA The detected energy is lower than the preset threshold, indicating that the channel is idle, and the U-Scell (i, 1) and U-Scell (i, 2) serving nodes can respectively use the unlicensed carrier resources that they preempt to perform the PDSCH data block. send. If the CCA detection fails, the serving node cannot use the corresponding resources to transmit the PDSCH data block. Therefore, the UE independently receives PDSCH data blocks from U-Scell (i, 1), U-Scell (i, 2), but cannot simultaneously receive multiple PDSCH data blocks. For the uplink, a single UE performs uplink CCA detection at a specific moment according to the rules and requirements of the FBE, and attempts to occupy an unlicensed carrier channel of 5260 MHz-5280 MHz; if the energy of the uplink CCA detection is lower than a preset threshold, it indicates that the channel is idle, and the single UE The PUSCH data block can be preempted and utilized by the unlicensed carrier resource, and the eNB can receive the U-Scell (i, 1), U-Scell (i, 2) service node to form the receive diversity. If the uplink CCA detection fails, the UE temporarily cannot transmit the PUSCH data block, and the time retreats to wait for the next preemption opportunity;
S207:UE按照和U-Scell(i,1),U-Scell(i,2)处于不同载波频点相同的方式,进行MAC协议层相关处理,下行MAC PDU接收和重排序,下行HARQ进程反馈,根据接收的结果,在授权宏小区Pcell上进行PUCCH上行反馈。U-Scell(i,1),U-Scell(i,2)服务节点把接收到的PUSCH数据块通过理想回传链路发回给eNB,eNB只要能从U-Scell(i,1),U-Scell(i,2)任意一个服务节点上正确接收到PUSCH数据块,就通过授权宏小区Pcell进行PHICH下行确认反馈,如果eNB无法从U-Scell(i,1)和U-Scell(i,2)正确接收到PUSCH数据块,则要求UE重传PUSCH数据块。S207: The UE performs MAC protocol layer correlation processing, downlink MAC PDU reception and reordering, and downlink HARQ process feedback according to the manner that the U-Scell (i, 1) and the U-Scell (i, 2) are in different carrier frequency points. According to the received result, the PUCCH uplink feedback is performed on the authorized macro cell Pcell. The U-Scell (i, 1), U-Scell (i, 2) serving node sends the received PUSCH data block back to the eNB through the ideal backhaul link, as long as the eNB can from the U-Scell (i, 1), If the PUSCH data block is correctly received on any of the service nodes of the U-Scell (i, 2), the PHICH downlink acknowledgement feedback is performed by the authorized macro cell Pcell, if the eNB cannot obtain the U-Scell (i, 1) and the U-Scell (i) 2) If the PUSCH data block is correctly received, the UE is required to retransmit the PUSCH data block.
需要说明的是,终端在采用本发明实施例提供的方法进行数据传输时,可以按照LTE技术进行上下行数据的传输,即按照协议中规定的辅服务小区处于不同载波频点相同前提下数据传输方式进行传输,也就是说,在采用本发明实施例的方法时,虽然辅服务小区的资源部署方式与协议规定的不同,但仍可以沿用协议中规定的方式进行数据传输,无需对相关技术中的传输机制做任何修改,即可充分发挥资源的利用率,实现简单方便。It should be noted that when the terminal performs data transmission by using the method provided by the embodiment of the present invention, the uplink and downlink data may be transmitted according to the LTE technology, that is, the data transmission is performed under the same premise that the secondary serving cell is in different carrier frequency points according to the protocol. The mode is transmitted, that is, when the method of the embodiment of the present invention is used, although the resource deployment mode of the secondary serving cell is different from that specified by the protocol, the data transmission may be performed in the manner specified in the protocol, without using the related technology. By making any modifications to the transmission mechanism, the utilization of resources can be fully utilized, and the implementation is simple and convenient.
