Priority of Chinese Patent Application, the entire contents of which is incorporated herein by reference. Technical field

本发明涉及通信技术领域，特别涉及一种传输方案和 /或反馈模式的配置方法和设备。背景技术 The present invention relates to the field of communications technologies, and in particular, to a transmission scheme and/or a configuration method and device for a feedback mode. Background technique

国际电信联盟 ( International Telecommunications Union , ITU ) 为下一代移动通信***一高级国际移动通信*** （ International Mobile Telecommunication Advanced, T-A ) 的性能提出了非常苛刻的要求。比如，最大***传输带宽达到 100MHz,上下行数据传输的峰值速率需要达到 lGbps和 500M bps, 并对***平均频谱效率尤其是边缘频谱效率提出了非常高的需求。 The International Telecommunications Union (ITU) puts very stringent requirements on the performance of the next generation of mobile communication systems, the International Mobile Telecommunication Advanced (T-A). For example, the maximum system transmission bandwidth reaches 100MHz, and the peak rate of uplink and downlink data transmission needs to reach 1Gbps and 500M bps, and there is a very high demand for the average spectrum efficiency of the system, especially the edge spectrum efficiency.

为了满足 T-A的新要求， 3GPP ( 3rd Generation Partnership Project 第三代合作伙伴计划）在其下一代移动蜂窝通信*** LTE-A中提出了采用协作多点传输技术 ( Coordinated Multi-Point Transmission/Reception , In order to meet the new requirements of T-A, 3GPP (3rd Generation Partnership Project) proposed Coordinated Multi-Point Transmission/Reception in its next-generation mobile cellular communication system LTE-A.

CoMP )来提高***的性能。协作多点传输技术通过地理位置上分离的多个小区的联合调度或者协同传输，提高用户接收信号质量，降低小区间的干扰，从而有效提高***容量和边缘用户频谱效率。一般来说，多个传输点是不同小区的基站。协作多点传输技术分下行的协同传输和上行的联合接收。 CoMP) to improve system performance. The coordinated multi-point transmission technology improves the quality of the received signal and reduces the interference between cells by the joint scheduling or coordinated transmission of multiple cells separated geographically, thereby effectively improving the system capacity and the spectrum efficiency of the edge users. In general, multiple transmission points are base stations of different cells. Cooperative multipoint transmission technology is divided into downlink coordinated transmission and uplink joint reception.

下行多点协同传输技术方案主要分为两类：联合调度和联合发送。联合调度是通过小区之间的时间、频率和空间资源的协调，为不同的 UE ( User Equipment , 用户设备 )分配互相正交的资源，避免相互之间的干扰。小区间的干扰是制约小区边缘 UE性能的主要因素，因此联合调度可以降低小区间的干扰，从而提高小区边缘 UE的性能。如图 1所示，为现有技术中的多小区联合调度的示意图，通过三个小区的联合调度，将可能会相互干扰的三个 UE调度了到相互正交的资源上，有效的避免了小区之间的干扰。 Downlink multipoint coordinated transmission technology solutions are mainly divided into two categories: joint scheduling and joint transmission. Joint scheduling allocates mutually orthogonal resources to different UEs (User Equipments) by coordinating time, frequency, and space resources between cells to avoid mutual interference. Small interval interference is the main factor that restricts the performance of cell edge UEs. Therefore, joint scheduling can be To reduce interference between cells, thereby improving the performance of the cell edge UE. As shown in FIG. 1 , which is a schematic diagram of multi-cell joint scheduling in the prior art, three UEs that may interfere with each other are scheduled to mutually orthogonal resources through joint scheduling of three cells, which effectively avoids Interference between cells.

与联合调度方案只有一个小区向 UE发送数据不同，联合发送方案中有多个小区同时向 UE发送数据，以增强 UE接收信号。如图 2所示，为现有技术中的多小区联合发送的示意图，三个小区在相同的资源上向一个 UE发送数据， UE同时接收多个小区的信号。一方面，来自多个小区的有用信号叠加可以提升 UE接收的信号质量，另一方面，通过联合发送也可以降低 UE受到的干扰，从而提高***性能。 Different from the joint scheduling scheme, only one cell sends data to the UE. In the joint transmission scheme, multiple cells simultaneously send data to the UE to enhance the UE receiving signals. As shown in FIG. 2, which is a schematic diagram of multi-cell joint transmission in the prior art, three cells transmit data to one UE on the same resource, and the UE simultaneously receives signals of multiple cells. On the one hand, the superposition of useful signals from multiple cells can improve the signal quality received by the UE. On the other hand, the joint transmission can also reduce the interference received by the UE, thereby improving system performance.

上行联合接收是指多个小区同时接收一个 UE发出的数据，各小区接收到的数据进行联合处理以提高 UE数据的解调质量。现有技术中的上行联合接收的示意图如图 3所示。 Uplink joint reception means that multiple cells simultaneously receive data sent by one UE, and the data received by each cell is jointly processed to improve the demodulation quality of the UE data. A schematic diagram of uplink joint reception in the prior art is shown in FIG.

在下行 CoMP中，为了配合 eNB ( evolved Node B , 演进的 Β节点，即 LTE基站 )进行合理的调度和传输， UE需要测量各小区的信道质量并进行反馈。 In the downlink CoMP, in order to perform reasonable scheduling and transmission with the eNB (evolved Node B, the evolved Β node, ie, the LTE base station), the UE needs to measure the channel quality of each cell and perform feedback.

在现有技术中， CoMP中定义的反馈类型包括以下三种： In the prior art, the types of feedback defined in CoMP include the following three types:

显式反馈：显式信道状态 /统计消息反馈，反馈的消息未进行任何处理； Explicit feedback: explicit channel status / statistical message feedback, the feedback message is not processed;

隐式反馈：隐式信道状态 /统计消息反馈，反馈经过处理的信息，如 CQI ( Channel Quality Indicator, 信道质量指示） /PMI ( Precoding Matrix Indicator, 预编码矩阵指示） / RI ( Rank Indicator, 等级指示）； Implicit feedback: implicit channel status/statistical message feedback, feedback processed information, such as CQI (Channel Quality Indicator) / PMI (Precoding Matrix Indicator) / RI ( Rank Indicator, level indication ) ;

SRS ( Sounding Reference Signal, 探测参考信号）方式：利用信道互易性， UE发送的 SRS可用于 eNB进行 CSI ( Channel State Information, 信道状态信息）估计。 SRS (Sounding Reference Signal) mode: With channel reciprocity, the SRS sent by the UE can be used by the eNB to perform CSI (Channel State Information) estimation.

现有的 LTE ( Long Term Evolution, 长期演进） ***中反馈模式 /类型是在无线资源控制协议（ Radio Resource Control, RRC )信令中通过显式或者隐式的方式通知的，是一个半静态的过程。对于不同的传输方案定义不同的传输模式，即反馈内容和开销不同，可以使得相应的开销降低，并配合传输方案达到更好的传输性能。 In the existing LTE (Long Term Evolution) system, the feedback mode/type is notified in an explicit or implicit manner in Radio Resource Control (RRC) signaling, which is semi-static. process. Different transmission modes are defined for different transmission schemes, that is, feedback content and overhead are different, which can reduce the corresponding overhead. Low, and with transmission scheme to achieve better transmission performance.

在实现本发明的过程中，申请人发现现有技术至少存在以下问题：当协同调度 /波束赋形方案和联合传输方案切换时，对应的反馈模式应该也相应的切换。如果两种方案被定义为两种传输模式，并且按照现有 LTE***规定的，通过 RRC信令来通知切换模式，那么和反馈模式一样都是半静态的切换。但是，如果考虑两种方案存在于一种传输模式中，按照网络侧的判断可以支持动态的快速切换，反馈模式这种用 RRC信令的切换模式就会无法支持方案的切换，这也使得方案的切换丧失了实际的意义。发明内容 In the process of implementing the present invention, the Applicant has found that the prior art has at least the following problems: When the cooperative scheduling/beamforming scheme and the joint transmission scheme are switched, the corresponding feedback mode should also be switched accordingly. If the two schemes are defined as two transmission modes and the handover mode is notified by RRC signaling as specified by the existing LTE system, it is a semi-static handover as the feedback mode. However, if two schemes are considered to exist in one transmission mode, dynamic fast handover can be supported according to the judgment of the network side, and the handover mode using the RRC signaling mode cannot support the handover of the scheme, which also makes the scheme The switch has lost its practical meaning.

具体实施方式 detailed description

如背景技术所述，现有技术用 RRC信令通知传输方案和反馈模式，无法快速的切换传输方案和对应的反馈类型。 As described in the background art, the prior art uses RRC signaling to notify the transmission scheme and the feedback mode, and cannot quickly switch the transmission scheme and the corresponding feedback type.

本发明实施例所提出的技术方案所采用的主要的解决方式是用物理控制信道来显示或者隐式的通知传输方案或者反馈类型。 The main solution adopted by the technical solution proposed by the embodiment of the present invention is to use a physical control channel to display or implicitly notify a transmission scheme or a feedback type.

本发明实施例的主要技术点是 CoMP中不同的下行传输方案对应不同的反馈模式，并且反馈模式中所包括的反馈内容和 /或开销不同；一方面，在 CoMP中，不同的下行传输方案之间可以动态快速的切换；其中， eNB选择是否使用 CoMP的传输方案，以及使用哪种传输方案，并通过以下方式进行切换： The main technical point of the embodiment of the present invention is that different downlink transmission schemes in the CoMP correspond to different feedback modes, and the feedback content and/or overhead included in the feedback mode are different; On the one hand, in CoMP, different downlink transmission schemes can be dynamically and rapidly switched; wherein, the eNB selects whether to use the CoMP transmission scheme, and which transmission scheme to use, and switches in the following manner:

方式一、硬切换传输方案：在现有传输方案不满足性能要求时，直接切换方案。 Method 1: Hard handover transmission scheme: When the existing transmission scheme does not meet the performance requirements, the scheme is directly switched.

方式二、根据一段时间的反馈内容来决策是否切换传输方案：该方式可以为设置两个反馈周期，较短的周期反馈（开销较小）满足现有传输方案的需要，较长的周期反馈（开销较大）满足所有传输方案的需要。 Manner 2: Determine whether to switch the transmission scheme according to the feedback content of a period of time: The method can set two feedback periods, and the shorter period feedback (small overhead) satisfies the needs of the existing transmission scheme, and the longer period feedback ( The overhead is large) to meet the needs of all transmission scenarios.

另一方面，在 CoMP中，不同的下行传输方案对应的不同的反馈模式也可以相应的快速切换。 On the other hand, in CoMP, different feedback modes corresponding to different downlink transmission schemes can also be quickly switched accordingly.

在本发明实施例所提出的技术方案中， eNB通过 RRC信令设置 UE的不同的反馈模式，以及对应的周期等配置参数，在多种反馈模式的设定过程中，可增加一组 RRC信令内的参数进行设置，也可以通过增加多组 RRC信令进行设置。 In the technical solution provided by the embodiment of the present invention, the eNB sets different feedback modes of the UE and configuration parameters such as corresponding periods through RRC signaling, and may add a group of RRC letters in the process of setting multiple feedback modes. The parameters in the command are set, and can also be set by adding multiple sets of RRC signaling.

在本发明实施例所提出的技术方案中，反馈模式的快速切换通过控制信道中的控制信令（如设置开关等）完成。 In the technical solution proposed by the embodiment of the present invention, the fast switching of the feedback mode is completed by controlling signaling (such as setting a switch) in the control channel.

如图 4所示，为本发明实施例所提出的一种传输方案和 /或反馈模式的配置方法的流程示意图，该方法具体包括以下步骤： FIG. 4 is a schematic flowchart of a method for configuring a transmission scheme and/or a feedback mode according to an embodiment of the present invention, where the method specifically includes the following steps:

步骤 S401、基站通过 PDCCH ( Physical Downlink Control Channel, 物理下行控制信道）向用户设备发送包含传输方案和 /或反馈模式信息的消息。 Step S401: The base station sends a message including a transmission scheme and/or feedback mode information to the user equipment by using a PDCCH (Physical Downlink Control Channel).

具体的，在本步骤之前，还包括以下的配置过程： Specifically, before this step, the following configuration process is also included:

基站通过 RRC信令配置不同的非周期反馈模式；或， The base station configures different aperiodic feedback modes through RRC signaling; or

基站通过 RRC信令配置不同的周期反馈模式，其中包括周期反馈模式所对应的上报资源索引、配置索引和格式信息。 The base station configures different periodic feedback modes through RRC signaling, including the reporting resource index, configuration index, and format information corresponding to the periodic feedback mode.

在此种情况下，如果存在多种反馈模式，则基站通过多组 RRC信令分别配置多个不同的非周期反馈模式或周期反馈模式，或通过一组 RRC 信令的不同参数配置多个不同的非周期反馈模式或周期反馈模式。其中，物理信道的控制信令通过改变现有的 DCI format 0 ( Downlink Control Information format 0 , 下行控制信息格式 0 )的显式指示和 /或隐式指示完成传输方案和 /或反馈模式信息的配置，具体说明如下： In this case, if there are multiple feedback modes, the base station separately configures multiple different aperiodic feedback modes or periodic feedback modes through multiple sets of RRC signaling, or configures multiple different parameters through different parameters of a group of RRC signaling. Aperiodic feedback mode or periodic feedback mode. The control signaling of the physical channel completes the configuration of the transmission scheme and/or the feedback mode information by changing an explicit indication and/or an implicit indication of the existing DCI format 0 (downlink control information format 0). , the specific instructions are as follows:

( 1 )显式配置方式，包括： (1) Explicit configuration methods, including:

基站在通过 PDCCH向用户设备所发送的消息中以不同的开关位指示不同的传输方案和 /或反馈模式；或， The base station indicates different transmission schemes and/or feedback modes with different switch bits in the message sent to the user equipment through the PDCCH; or

基站在通过 PDCCH向用户设备所发送的消息中以不同的比特位指示不同的传输方案和 /或反馈模式。 The base station indicates different transmission schemes and/or feedback modes with different bits in the message transmitted to the user equipment through the PDCCH.

即在 DCI format 0 中设置开关位或比特位指示不同的 CoMP传输方案。 That is, setting the switch bit or bit in DCI format 0 indicates a different CoMP transmission scheme.

考虑尽量减少比特位的扩展，可以用 lbit的开销表示协同调t/协作波束赋形 ( Coordinated Scheduling/ Coordinated Beam Forming , CS/CBF )和联合处理（Joint Processing, JP ) 两种传输方案，或者用 2bits开销表示细化的传输方案，在实际的应用场景中，不排除有其他的开关位表示 CoMP 传输方案的方法。 Considering to minimize the expansion of the bit, you can use the lbit overhead to represent Coordinated Scheduling/Coordinated Beam Forming (CS/CBF) and Joint Processing (JP) transmission schemes, or The 2bits overhead represents a refined transmission scheme. In the actual application scenario, other methods for indicating a CoMP transmission scheme are not excluded.

在具体的实施场景中，反馈不同的内容的方式为反馈类型不变，但是根据开关位所指示的传输方案使得 UE得知需要相应反馈不同的内容。 In a specific implementation scenario, the manner of feeding back different content is that the feedback type is unchanged, but according to the transmission scheme indicated by the switch bit, the UE knows that the content needs to be fed back differently.

对于某些反馈类型，需要 RRC增加信令通知小区个数；反馈类型相应于传输方案进行扩展，即增加新的反馈类型；对于后者开关位控制的传输方案对应一个或者多个反馈类型。 For some types of feedback, RRC needs to increase signaling to notify the number of cells; the feedback type is extended corresponding to the transmission scheme, that is, a new feedback type is added; and the transmission scheme controlled by the latter is corresponding to one or more feedback types.

其中，反馈可以是周期的，也可以是非周期的。 Among them, the feedback can be periodic or acyclic.

周期性反馈是指在 PUCCH ( Physical Uplink Control Channel, 物理上行控制信道）情况下，可以扩展反馈的类型，或者仅通过配置周期和 offset (偏移量）来区分不同小区的反馈，或在 PUSCH情况下，可以扩展反馈的类型，或者通过配置周期和 offset来区分不同小区的反馈，或者通过如上的开关位重用现有的反馈类型，或通过配置周期和 offset重用现有的反馈类型。 The periodic feedback refers to the type of feedback that can be extended in the case of the PUCCH (Physical Uplink Control Channel), or the feedback of different cells can be distinguished only by the configuration period and the offset (offset), or in the PUSCH case. Next, the type of feedback can be extended, or the feedback of different cells can be distinguished by configuring the period and offset, or the existing feedback type can be reused by the switch bit as above, or the existing feedback type can be reused by the configuration period and offset.

在反馈模式扩展的情况下，开关位也可以直接指示不同的反馈模式这时开关位对应的反馈模式可与 RRC信令通知的反馈模式顺序一致。 In the case of extended feedback mode, the switch bits can also directly indicate different feedback modes. At this time, the feedback mode corresponding to the switch bit can be in the same order as the feedback mode of the RRC signaling notification.

对 CQI request比特位进行扩展（现在为 lbit ) , 用于指示周期和非周期、或者 CoMP的不同方案或者不同反馈模式。 The CQI request bit is extended (now lbit) to indicate periodic and non-periodic, or CoMP different schemes or different feedback modes.

( 2 ) 隐式配置方式，包括： (2) Implicit configuration methods, including:

基站在通过 PDCCH向用户设备所发送的消息中以不同的参数取值范围指示不同的传输方案和 /或反馈模式；或， The base station indicates different transmission schemes and/or feedback modes in different message parameter ranges in the message sent to the user equipment through the PDCCH; or

基站在通过 PDCCH向用户设备所发送的消息中以不同的 RNTI ( Radio Network Temporary Identifiery, 无线网络临时标识 )指示不同的传输方案和 /或反馈模式。 The base station indicates different transmission schemes and/or feedback modes with different RNTIs (Radio Network Temporary Identifiers) in the messages sent to the user equipment through the PDCCH.

( 3 )显式和隐式的混合配置方式，包括： (3) Explicit and implicit hybrid configurations, including:

基站在通过 PDCCH向用户设备所发送的消息中以不同的开关位或比特位指示不同的传输方案，并以不同的参数取值范围或 RNTI指示不同的反馈模式。 The base station indicates different transmission schemes with different switch bits or bit bits in the message sent to the user equipment through the PDCCH, and indicates different feedback modes with different parameter value ranges or RNTIs.

其中，在隐式配置方式或显式和隐式的混合配置方式中，不同的参数取值范围包括用户设备通过上行共享信道传输控制信令时，上行共享信道中所传输的资源块的大小或 MCS ( Modulation and Coding Scheme, 调制和编码方案）等级，基站通过资源块的大小或 MCS等级区分不同的反馈内容或反馈类型。 In the implicit configuration mode or the explicit and implicit hybrid configuration mode, the value range of the different parameters includes the size of the resource block transmitted in the uplink shared channel when the user equipment transmits the control signaling through the uplink shared channel. MCS (Modulation and Coding Scheme) level, the base station distinguishes different feedback content or feedback type by the size of the resource block or the MCS level.

步骤 S402、基站接收用户设备按照传输方案和 /或反馈模式信息所对应的方式反馈的反馈内容。 Step S402: The base station receives feedback content that is fed back by the user equipment according to a manner corresponding to the transmission scheme and/or the feedback mode information.

本步骤完成之后，还可以进一步的包括以下的切换流程： After this step is completed, the following switching process may be further included:

步骤 S403、基站根据反馈内容判断是否需要切换用户设备的传输方案和 /或反馈模式。 Step S403: The base station determines, according to the feedback content, whether the transmission scheme and/or the feedback mode of the user equipment needs to be switched.

如果基站判断需要切换，则执行步骤 S404; If the base station determines that the handover is required, step S404 is performed;

如果基站判断不需要切换，则保持现有的传输方案和 /或反馈模式。步骤 S404、基站在得到用户设备发送的相应的反馈内容后进行传输方案的切换。 If the base station determines that no handover is required, then the existing transmission scheme and/or feedback mode is maintained. Step S404: The base station performs handover of the transmission scheme after obtaining the corresponding feedback content sent by the user equipment.

本步骤具体包括以下两种情况：情况一、基站直接将当前的传输方案切换到新的传输方案。 This step specifically includes the following two situations: Case 1: The base station directly switches the current transmission scheme to the new transmission scheme.

情况二、基站根据预设的时间范围内的反馈内容判断是否将当前的传输方案切换到新的传输方案。 Case 2: The base station determines whether to switch the current transmission scheme to the new transmission scheme according to the feedback content in the preset time range.

具体的，此种情况中，基站可以设置两个反馈周期，以开销较小的反馈周期满足现有的传输方案，以开销较大的反馈周期满足新的传输方案。 Specifically, in this case, the base station can set two feedback periods, satisfy the existing transmission scheme with a less expensive feedback period, and satisfy the new transmission scheme with a larger overhead feedback period.

进一步的，基站还可以通过 RRC信令指示开销较大的反馈周期的反馈，使用户设备在到达开销较大的反馈周期的时间点时，根据 RRC信令的配置进行反馈； Further, the base station may further indicate that the feedback period of the feedback period is greater by the RRC signaling, so that the user equipment feeds back according to the configuration of the RRC signaling when the time interval of the feedback period with a large overhead is reached;

其中， RRC信令中对于开销较大的反馈周期的反馈的配置通过开关位配置，或缺省配置。 The configuration of the feedback of the feedback period with a large overhead in the RRC signaling is configured by a switch bit, or a default configuration.

通过应用本发明的技术方案，可以实现不同的 CoMP传输方案对应不同的反馈模式，能更好的节省反馈资源，并且用物理层控制信道的设置开关的方法相对于原来的 RRC信令通知能够更快的切换传输方案和反馈模式。下面，结合具体的实施场景，对本发明实施例所提出的技术方进行详细说明。 By applying the technical solution of the present invention, different CoMP transmission schemes can be implemented corresponding to different feedback modes, which can better save feedback resources, and the method of setting switches of the physical layer control channel can be more advanced than the original RRC signaling notification. Fast switching transmission scheme and feedback mode. The technical party proposed in the embodiments of the present invention will be described in detail below with reference to specific implementation scenarios.

如图 5所示，本发明实施例提出了一种传输方案和 /或反馈模式的配置方法，通过应用本方法， UE在 PUSCH上进行非周期的 CQI上报，具体包括以下步骤： As shown in FIG. 5, the embodiment of the present invention provides a configuration method of a transmission scheme and/or a feedback mode. By applying the method, the UE performs aperiodic CQI reporting on the PUSCH, which specifically includes the following steps:

步骤 S501、 eNB通过 RRC信令通知 UE采用非周期的 CQ 馈模式。其中，相应的各种具体的反馈模式的设定和现有的 R8标准相同， RRC 信令的格式构成在本实施例中也不做改变，具体如表 1所示。 Step S501: The eNB notifies the UE to adopt an aperiodic CQ feed mode by using RRC signaling. The configuration of the corresponding specific feedback mode is the same as that of the existing R8 standard, and the format of the RRC signaling is not changed in this embodiment, as shown in Table 1.

非周期的 CQL^馈模式中各种反馈模式的对应关系 Correspondence of various feedback modes in aperiodic CQL feed mode

UE Selected Mode 2-0 Mode 2-2

(subband CQI) (subband CQI)

Higher Layer-configured Mode 3-0 Mode 3-1 Higher Layer-configured Mode 3-0 Mode 3-1

(subband CQI) (subband CQI)

步骤 S502、 eNB选择是否使用 CoMP的传输方案，如果使用 CoMP的传输方案， eNB进一步确定 UE采用哪种传输方案。 Step S502: The eNB selects whether to use the transmission scheme of the CoMP. If the transmission scheme of the CoMP is used, the eNB further determines which transmission scheme the UE adopts.

步骤 S503、 eNB通过下行物理控制信道（PDCCH )向 UE发送传输方案和反馈模式的设定。 Step S503: The eNB sends the setting of the transmission scheme and the feedback mode to the UE by using a downlink physical control channel (PDCCH).

由于在步骤 S501中已经通过 RRC信令通知 UE采用非周期的 CQL^馈模式，所以本步骤中进一步在 PDCCH中发送 DCI format 0指示 UE在非周期的 CQL^馈模式中所采用的反馈信道和传输方案。 Since the UE has been notified by the RRC signaling in step S501 to adopt the aperiodic CQL feed mode, the DCI format 0 is further transmitted in the PDCCH in this step to indicate the feedback channel used by the UE in the aperiodic CQL feed mode. Transmission scheme.

在本实施例中， eNB在 PDCCH上发送的 DCI format 0中的 CQI request = 1 , 表示 UE通过 PUSCH进行反馈。 In this embodiment, the CQI request = 1 in the DCI format 0 sent by the eNB on the PDCCH indicates that the UE feeds back through the PUSCH.

另一方面， eNB在 DCI format 0 中用开关位指示反馈模式所对应的传输方案，为了尽量减少比特位的扩展，可以采用以下表 2所示的形式表示传输方案： On the other hand, the eNB uses the switch bit in DCI format 0 to indicate the transmission scheme corresponding to the feedback mode. In order to minimize the bit extension, the transmission scheme can be expressed in the form shown in Table 2 below:

开关位与传输方案的对应关系

Correspondence between switch bit and transmission scheme

在此种情况下，比特位的占用是 lbit, 但是此种情况下只能表示两种传输方案，如果***中存在更多的传输方案，则受制于比特位的限制而不能表示，因此，可以进一步通过扩展比特位来表示更加细化的传输方案，具体如表 3所示： In this case, the occupancy of the bit is lbit, but in this case, only two transmission schemes can be represented. If there are more transmission schemes in the system, it is limited by the bit and cannot be represented. Therefore, Further, the extended bit is used to represent a more detailed transmission scheme, as shown in Table 3:

细化的开关位与传输方案的对应关系 Corresponding relationship between the refined switch bits and the transmission scheme

需要指出的是，上述的开关位设置方法和对应的传输方案仅是本发明实施例为了方便说明而给出的一种示例，在具体的应用场景中，不排除有其他的开关位表示 CoMP传输方案的方法，这同样属于本发明的保护范围。 It should be noted that the above-mentioned switch bit setting method and the corresponding transmission scheme are only an example given in the embodiment of the present invention for convenience of description. In a specific application scenario, In addition to other switching bits representing the method of the CoMP transmission scheme, this also falls within the scope of the present invention.

步骤 S504、 UE通过 DCI format 0设置的开关位在 PUSCH中反馈满足传输方案的反馈内容。 Step S504: The UE feeds back the feedback content that satisfies the transmission scheme in the PUSCH by using the switch bit set by the DCI format 0.

例如， DCI format 0中设置的开关位为 10, UE采用相干联合传输的方案，因此如表 1所示，可以对应的反馈模式为 mode 3-1、 mode 2-2或者 mode 1-2。和现有 LTE***不同的是，对于 mode 3-1 , PMI是多个小区联合处理得到的 PMI, CQI也可以理解为服务小区的单个 CQI, 或者对应多个小区联合处理的 PMI的 CQI。 For example, the switch bit set in DCI format 0 is 10, and the UE adopts the scheme of coherent joint transmission. Therefore, as shown in Table 1, the corresponding feedback mode can be mode 3-1, mode 2-2 or mode 1-2. Different from the existing LTE system, for mode 3-1, the PMI is a PMI obtained by combining multiple cells, and the CQI can also be understood as a single CQI of the serving cell, or a CQI corresponding to the PMI of multiple cells jointly processed.

另外，对于相干联合传输的方案，相应的反馈模式中还可反馈对应多个小区的多个 PMI和一个补充的 PMI对应相位校准，这同样也属于 mode 1-2和 mode 2-2的反馈内容范围。其中，小区个数需要高层配置，可在 RRC 信令中增加参数 c表示，在单小区情况下参数 c=l。 In addition, for the coherent joint transmission scheme, the corresponding feedback mode may also feed back multiple PMIs corresponding to multiple cells and one complementary PMI corresponding phase calibration, which also belongs to the feedback contents of mode 1-2 and mode 2-2. range. The number of cells needs to be configured at a high level, and the parameter c can be added in the RRC signaling, and the parameter c=l in the case of a single cell.

具体的 RRC信令示例如下： Specific RRC signaling examples are as follows:

CQI-ReportConfig ::= SEQUENCE { CQI-ReportConfig ::= SEQUENCE {

cqi-ReportMode Aperiodic ENUMERATED { cqi-ReportMode Aperiodic ENUMERATED {

rml2, nn20, rm22, rm30, rm31, Rml2, nn20, rm22, rm30, rm31,

rmA, rmB, spare 1 } OPTIONAL, - Need OR rmA, rmB, spare 1 } OPTIONAL, - Need OR

nomPDSCH-RS-EPRE-Offset INTEGER (-1..6), nomPDSCH-RS-EPRE-Offset INTEGER (-1..6),

cqi-ReportPeriodic CQI-ReportPeriodic OPTIONAL - Need ON cqi-ReportPeriodic CQI-ReportPeriodic OPTIONAL - Need ON

} }

步骤 S505、 eNB接收 UE所反馈的当前传输方案的反馈内容。 Step S505: The eNB receives the feedback content of the current transmission scheme fed back by the UE.

当 eNB参考当前传输方案的反馈内容，认为需要切换传输方案，将要求 UE反馈新的传输方案的反馈内容，并在收到相应的反馈内容后切换到新的传输方案。 When the eNB refers to the feedback content of the current transmission scheme and considers that the transmission scheme needs to be switched, the UE is required to feed back the feedback content of the new transmission scheme, and then switches to the new transmission scheme after receiving the corresponding feedback content.

通过应用本发明的技术方案，可以实现不同的 CoMP传输方案对应不同的反馈模式，能更好的节省反馈资源，并且用物理层控制信道的设置开关的方法相对于原来的 RRC信令通知能够更快的切换传输方案和反馈模式。如图 6所示，本发明实施例提出了另一种传输方案和 /或反馈模式的配置方法，通过应用本方法， UE在 PUSCH上进行非周期的 CQI上报，具体包括以下步骤： By applying the technical solution of the present invention, different CoMP transmission schemes can be implemented corresponding to different feedback modes, which can better save feedback resources, and use physical layer control channel settings. The switch method can switch the transmission scheme and feedback mode faster than the original RRC signaling. As shown in FIG. 6, the embodiment of the present invention provides another method for configuring a transmission scheme and/or a feedback mode. The UE performs aperiodic CQI reporting on the PUSCH by using the method. The method includes the following steps:

步骤 S601、 eNB通过 RRC信令通知 UE采用包含新的反馈类型的非周期的 CQL^馈模式。 Step S601: The eNB informs the UE by using RRC signaling to adopt a non-periodic CQL feed mode including a new feedback type.

与前述实施例不同的是，在本步骤中对反馈类型进行扩展：非周期的 CQL^馈模式中除原有的 R8标准中的各种反馈类型外，还进一步添加针对协同调度 /波束赋形的反馈模式 rmA和联合传输的反馈模式 rmB。 Different from the foregoing embodiment, the feedback type is extended in this step: In addition to various feedback types in the original R8 standard, the non-periodic CQL feed mode is further added for cooperative scheduling/beamforming. The feedback mode rmA and the joint transmission feedback mode rmB.

在具体的应用场景中，可以用一条 RRC信令通知两个或者以上的反馈模式，或者用多条 RRC信令分别通知， RRC信令数量的变化并不影响本发明的保护范围。 In a specific application scenario, two or more feedback modes may be notified by using one RRC signaling, or separately notified by multiple RRC signalings, and the change of the number of RRC signaling does not affect the protection scope of the present invention.

t匕 ^口： T匕 ^ mouth:

CQI-ReportConfig ::= SEQUENCE { CQI-ReportConfig ::= SEQUENCE {

cqi-ReportMode Aperiodic 1 ENUMERATED { cqi-ReportMode Aperiodic 1 ENUMERATED {

nnl2, rm20, rm22, rm30, rm31, Nnl2, rm20, rm22, rm30, rm31,

rmA, rmB, spare 1 } OPTIONAL, - Need OR cqi-ReportModeAperiodic2 ENUMERATED { rmA, rmB, spare 1 } OPTIONAL, - Need OR cqi-ReportModeAperiodic2 ENUMERATED {

} }

其中， cqi-ReportModeAperiodicl表示前述的针对协同调度 /波束赋形的反馈模式 rmA , cqi-ReportModeAperiodic2表示前述的针对联合传输的反馈模式 rmB。步骤 S602、 eNB选择是否使用 CoMP的传输方案，如果使用 CoMP的传输方案， eNB进一步确定 UE采用哪种传输方案。 Where cqi-ReportModeAperiodic1 represents the aforementioned feedback mode rmA for cooperative scheduling/beamforming, and cqi-ReportModeAperiodic2 represents the aforementioned feedback mode rmB for joint transmission. Step S602: The eNB selects whether to use the transmission scheme of CoMP. If the transmission scheme of CoMP is used, the eNB further determines which transmission scheme the UE adopts.

步骤 S603、 eNB通过 PDCCH向 UE发送传输方案和反馈模式的设定。与前述实施例相类似的，由于在步骤 S601中已经通过 RRC信令通知 Step S603: The eNB sends a setting of a transmission scheme and a feedback mode to the UE through the PDCCH. Similar to the foregoing embodiment, since RRC signaling has been notified in step S601

UE采用非周期的 CQ 馈模式，所以本步骤中进一步在 PDCCH中发送The UE adopts a non-periodic CQ feed mode, so this step is further sent in the PDCCH.

DCI format 0指示 UE在非周期的 CQ 馈模式中所采用的反馈信道和传输方案。 DCI format 0 indicates the feedback channel and transmission scheme employed by the UE in the aperiodic CQ feed mode.

另一方面， eNB在 DCI format 0 中用开关位指示反馈模式所对应的传输方案，为了尽量减少比特位的扩展，同样可以采用上述表 2所示的形式以及表 3所示的更加细化的形式表示传输方案。 On the other hand, the eNB uses the switch bit in the DCI format 0 to indicate the transmission scheme corresponding to the feedback mode. In order to minimize the bit extension, the form shown in Table 2 above and the more refined one shown in Table 3 can also be used. The form represents the transmission scheme.

其中，各开关位分别对应上述的两个参数，例如：相对于采用上述表 2所示的形式所表示传输方案，开关位 0对应 cqi-ReportModeAperiodicl, 开关位 1对应 cqi-ReportModeAperiodic2。 The switch bits respectively correspond to the above two parameters, for example: Compared with the transmission scheme represented by the form shown in Table 2 above, the switch bit 0 corresponds to cqi-ReportModeAperiodicl, and the switch bit 1 corresponds to cqi-ReportModeAperiodic2.

在具体的应用场景中，如果是两条 RRC信令，则可以通过 RRC信令发送的时间顺序来确定传输方案和反馈类型的对应。 In a specific application scenario, if there are two RRC signaling, the correspondence between the transmission scheme and the feedback type may be determined by the chronological order of the RRC signaling.

需要指出的是，上述的开关位设置方法和对应的传输方案仅是本发明实施例为了方便说明而给出的一种示例，在具体的应用场景中，不排除有其他的开关位表示 CoMP传输方案的方法，这同样属于本发明的保护范围。 It should be noted that the above-mentioned switch bit setting method and the corresponding transmission scheme are only an example given in the embodiment of the present invention for convenience of description. In a specific application scenario, other switch bits are not excluded to indicate CoMP transmission. The method of the solution is also within the scope of protection of the present invention.

步骤 S604、 UE通过 DCI format 0设置的开关位在 PUSCH中反馈满足传输方案的反馈内容。 Step S604: The UE feeds back the feedback content that satisfies the transmission scheme in the PUSCH by using the switch bit set by the DCI format 0.

后续如果存在传输方案切换的情况，则参考前述实施例，在本实施例中不再赘述。 If there is a case where the transmission scheme is switched, refer to the foregoing embodiment, and details are not described in this embodiment.

通过应用本发明的技术方案，可以实现不同的 CoMP传输方案对应不同的反馈模式，能更好的节省反馈资源，并且用物理层控制信道的设置开关的方法相对于原来的 RRC信令通知能够更快的切换传输方案和反馈模式。如图 7所示，本发明实施例提出了另一种传输方案和 /或反馈模式的配置方法，通过应用本方法， UE在 PUCCH上进行周期的 CQI上报，具体包括以下步骤： By applying the technical solution of the present invention, different CoMP transmission schemes can be implemented corresponding to different feedback modes, which can better save feedback resources, and the method of setting switches of the physical layer control channel can be more advanced than the original RRC signaling notification. Fast switching transmission scheme and feedback Mode. As shown in FIG. 7, the embodiment of the present invention provides another method for configuring a transmission scheme and/or a feedback mode. By applying the method, the UE performs periodic CQI reporting on the PUCCH, and specifically includes the following steps:

步骤 S701、 eNB通过 RRC信令通知 UE进行周期的 CQI上报所对应的资源索引、配置索引和 CQI格式等配置信息。 Step S701: The eNB notifies the UE to perform configuration information such as a resource index, a configuration index, and a CQI format corresponding to the periodic CQI reporting by using the RRC signaling.

步骤 S702、 eNB选择是否使用 CoMP的传输方案，如果使用 CoMP的传输方案， eNB进一步确定 UE采用哪种传输方案。 Step S702: The eNB selects whether to use the transmission scheme of the CoMP. If the transmission scheme of the CoMP is used, the eNB further determines which transmission scheme the UE adopts.

步骤 S703、 eNB通过 PDCCH向 UE发送传输方案和反馈模式的设定。与前述实施例相类似的，由于在步骤 S701中已经通过 RRC信令通知 UE采用周期的 CQL^馈模式，所以本步骤中进一步在 PDCCH中发送 DCI format 0指示 UE在周期的 CQ 馈模式中所采用的反馈信道和传输方案。 Step S703: The eNB sends a setting of a transmission scheme and a feedback mode to the UE through the PDCCH. Similar to the foregoing embodiment, since the UE has been notified by the RRC signaling in step S701 to adopt the periodic CQL feed mode, the DCI format 0 is further transmitted in the PDCCH in this step to indicate that the UE is in the periodic CQ feed mode. Feedback channel and transmission scheme adopted.

在本实施例中， eNB在 PDCCH上发送的 DCI format 0中的 CQI request 不设置为 1 , 即表示 UE不通过 PUSCH进行反馈，而是通过 PUCCH进行反贝。 In this embodiment, the CQI request in the DCI format 0 sent by the eNB on the PDCCH is not set to 1, which means that the UE does not feed back through the PUSCH, but performs an inversion through the PUCCH.

步骤 S704、 UE通过 DCI format 0设置的开关位在 PUCCH中反馈满足传输方案的反馈内容。 Step S704: The UE feeds back the feedback content that satisfies the transmission scheme in the PUCCH by using the switch bit set by the DCI format 0.

步骤 S705、 eNB接收 UE所反馈的当前传输方案的反馈内容。 Step S705: The eNB receives the feedback content of the current transmission scheme fed back by the UE.

步骤 S706、当 eNB参考当前传输方案的反馈内容，认为需要切换传输方案，将要求 UE反馈新的传输方案的反馈内容，并在收到相应的反馈内容后切换到新的传输方案。具体的，决定切换传输方案可根据以下两种方式： Step S706: When the eNB refers to the feedback content of the current transmission scheme and considers that the transmission scheme needs to be switched, the UE is required to feed back the feedback content of the new transmission scheme, and then switches to the new transmission scheme after receiving the corresponding feedback content. Specifically, the decision to switch the transmission scheme can be as follows:

方式一、硬切换传输方案：在现有传输方案不满足性能要求时，直接切换到新的传输方案。 Method 1: Hard handover transmission scheme: When the existing transmission scheme does not meet the performance requirements, it directly switches to the new transmission scheme.

在此种方式下，可以预先设置首选的切换传输方案。 In this way, the preferred switching transmission scheme can be preset.

方式二、根据一段时间的反馈内容来决策是否切换传输方案。 Method 2: Determine whether to switch the transmission scheme according to the feedback content for a period of time.

在此种方式下，可以根据开销大小预先设置长短两个反馈周期，其中，短周期反馈 (开销较小 )满足现有传输方案的需要，长周期反馈 (开销较大）满足所有传输方案的需要。 In this mode, two feedback periods can be set in advance according to the size of the overhead. The short-cycle feedback (small overhead) meets the requirements of the existing transmission scheme, and the long-cycle feedback (higher overhead) meets the requirements of all transmission schemes. .

对于第二种方式，可单独增加一条 RRC信令来指示长周期的反馈，无论切换到哪种短周期反馈，当到达长周期反馈的时间点时， UE都按照这条 RRC信令的配置进行长周期反馈。其中，该 RRC信令中的配置信息可以用开关位指示，也可作为缺省配置。 For the second mode, a single RRC signaling may be added to indicate long-term feedback. Regardless of which short-cycle feedback is switched, when the time of the long-cycle feedback is reached, the UE performs the RRC signaling configuration. Long cycle feedback. The configuration information in the RRC signaling may be indicated by a switch bit or a default configuration.

通过应用本发明的技术方案，可以实现不同的 CoMP传输方案对应不同的反馈模式，能更好的节省反馈资源，并且用物理层控制信道的设置开关的方法相对于原来的 RRC信令通知能够更快的切换传输方案和反馈模式。如图 8所示，本发明实施例提出了另一种传输方案和 /或反馈模式的配置方法，通过应用本方法， UE在 PUCCH上进行周期的 CQI上报，具体包括以下步骤： By applying the technical solution of the present invention, different CoMP transmission schemes can be implemented corresponding to different feedback modes, which can better save feedback resources, and the method of setting switches of the physical layer control channel can be more advanced than the original RRC signaling notification. Fast switching transmission scheme and feedback mode. As shown in FIG. 8, the embodiment of the present invention provides another method for configuring a transmission scheme and/or a feedback mode. By applying the method, the UE performs periodic CQI reporting on the PUCCH, and specifically includes the following steps:

步骤 S801、 eNB通过多条 RRC通知 UE进行周期的 CQI上报所对应的资源索引、配置索引和 CQI格式等配置信息所对应的不同的反馈模式。 Step S801: The eNB notifies the UE to perform different feedback modes corresponding to the configuration information such as the resource index, the configuration index, and the CQI format corresponding to the periodic CQI report by using multiple RRCs.

}, },

其中， cqi-ReportPeriodicl对应反馈模式 A, cqi-ReportPeiodic2对应反馈模式 B。 Among them, cqi-ReportPeriodic1 corresponds to feedback mode A, and cqi-ReportPeiodic2 corresponds to feedback mode B.

步骤 S802、 eNB选择是否使用 CoMP的传输方案，如果使用 CoMP的传输方案， eNB进一步确定 UE采用哪种传输方案。 Step S802: The eNB selects whether to use the transmission scheme of the CoMP. If the transmission scheme of the CoMP is used, the eNB further determines which transmission scheme the UE adopts.

步骤 S803、 eNB通过 PDCCH向 UE发送传输方案和反馈模式的设定。与前述实施例相类似的，由于在步骤 S801中已经通过 RRC信令通知 UE采用周期的 CQ 馈模式，所以本步骤中进一步在 PDCCH中发送 DCI format 0指示 UE在周期的 CQ 馈模式中所采用的反馈信道和传输方案。 Step S803: The eNB sends a setting of a transmission scheme and a feedback mode to the UE through the PDCCH. Similar to the foregoing embodiment, since the UE has been notified by the RRC signaling to adopt the periodic CQ feed mode in step S801, the DCI format 0 is further transmitted in the PDCCH in this step to indicate that the UE is used in the periodic CQ feed mode. Feedback channel and transmission scheme.

对于如表 2所示的形势所表示的传输方案，两个开关位分别对应两条 RRC信令，例如：相对于采用上述表 2所示的形式所表示传输方案，开关位 0对应 cqi-ReportPeriodicl ,开关位 1对应 cqi-ReportPeiodic2 , 由于存在两条 RRC信令，所以通过 RRC信令的发送时间顺序确定传输方案和反馈类型的对应。 For the transmission scheme represented by the situation shown in Table 2, the two switch bits respectively correspond to two RRC signaling, for example: Compared with the transmission scheme represented by the form shown in Table 2 above, the switch bit 0 corresponds to cqi-ReportPeriodicl The switch bit 1 corresponds to cqi-ReportPeiodic2. Since there are two RRC signaling, the correspondence between the transmission scheme and the feedback type is determined by the transmission time sequence of the RRC signaling.

步骤 S804、 UE通过 DCI format 0设置的开关位在 PUCCH中反馈满足传输方案的反馈内容。 Step S804: The UE feeds back the feedback content of the transmission scheme in the PUCCH through the switch bit set by the DCI format 0.

步骤 S805、 eNB接收 UE所反馈的当前传输方案的反馈内容。 Step S805: The eNB receives the feedback content of the current transmission scheme fed back by the UE.

步骤 S806、当 eNB参考当前传输方案的反馈内容，认为需要切换传输方案，将要求 UE反馈新的传输方案的反馈内容，并在收到相应的反馈内容后切换到新的传输方案。 Step S806: When referring to the feedback content of the current transmission scheme, the eNB considers that the handover scheme needs to be switched, and the UE is required to feed back the feedback content of the new transmission scheme, and then switches to the new transmission scheme after receiving the corresponding feedback content.

具体的，决定切换传输方案可根据以下两种方式： Specifically, the decision to switch the transmission scheme can be as follows:

方式二、根据一段时间的反馈内容来决策是否切换传输方案。在此种方式下，可以根据开销大小预先设置长短两个反馈周期，其中，短周期反馈 (开销较小 )满足现有传输方案的需要，长周期反馈 (开销较大）满足所有传输方案的需要。 Method 2: Determine whether to switch the transmission scheme according to the feedback content for a period of time. In this mode, two feedback periods can be set in advance according to the size of the overhead. The short-cycle feedback (small overhead) meets the requirements of the existing transmission scheme, and the long-cycle feedback (higher overhead) meets the requirements of all transmission schemes. .

对于第二种方式，可单独增加一条 RRC信令来指示长周期的反馈 , 无论切换到哪种短周期反馈，当到达长周期反馈的时间点时， UE都按照这条 RRC信令的配置进行长周期反馈。其中，该 RRC信令中的配置信息可以用开关位指示，也可作为缺省配置。 For the second mode, a single RRC signaling may be added to indicate long-term feedback. Regardless of which short-cycle feedback is switched, when the time of the long-cycle feedback is reached, the UE performs the RRC signaling configuration. Long cycle feedback. The configuration information in the RRC signaling may be indicated by a switch bit or a default configuration.

通过应用本发明的技术方案，可以实现不同的 CoMP传输方案对应不同的反馈模式，能更好的节省反馈资源，并且用物理层控制信道的设置开关的方法相对于原来的 RRC信令通知能够更快的切换传输方案和反馈模式。再进一步的，如图 9和图 10所示，本发明实施例提出了另一种传输方案和 /或反馈模式的配置方法，通过应用本方法， UE在 PUCCH上进行周期的 CQI上报。 By applying the technical solution of the present invention, different CoMP transmission schemes can be implemented corresponding to different feedback modes, which can better save feedback resources, and the method of setting switches of the physical layer control channel can be more advanced than the original RRC signaling notification. Fast switching transmission scheme and feedback mode. Further, as shown in FIG. 9 and FIG. 10, the embodiment of the present invention provides another method for configuring a transmission scheme and/or a feedback mode. By applying the method, the UE performs periodic CQI reporting on the PUCCH.

在本实施例中，步骤 S901至 S902、步骤 S904至 S905与前述的图 7所示的实施例相同，步骤 S1001至 S1002、步骤 S1004至 S1005与前述的图 8所示的实施例相同，只有步骤 S903和步骤 S1003存在区别，即在步骤 S903和步骤 S1003中， eNB在 PDCCH上发送的 DCI format 0中的 CQI request = 1 , 表示 UE通过 PUSCH进行反馈。 In this embodiment, steps S901 to S902 and steps S904 to S905 are the same as the embodiment shown in FIG. 7, and steps S1001 to S1002 and steps S1004 to S1005 are the same as the embodiment shown in FIG. 8 described above, and only steps are performed. S903 and step S1003 are different. In step S903 and step S1003, the CQI request = 1 in the DCI format 0 transmitted by the eNB on the PDCCH indicates that the UE performs feedback through the PUSCH.

通过上述说明可以看出，在 PUCCH中只能实现周期的 CQL^馈模式，哪种 CQL^馈模式，根据***要求进行设置。再进一步的，对于上述的各实施例所说明的技术方案，都可以通过扩展 CQI-request的比特位的方式来代替开关位的设置方式。 It can be seen from the above description that only the periodic CQL feed mode can be realized in the PUCCH, and which CQL feed mode is set according to the system requirements. Furthermore, for the technical solutions described in the above embodiments, the setting of the CQI-request bit can be used instead of the setting of the switch bit.

在这种情况下，大部分步骤与前述各实施例相同，在是在第三步存在区别。各实施例中的第三步中， eNB通过 PDCCH向 UE发送传输方案和反馈模式的设定的方式不再是通过 DCI format 0中的开关位设置，而是通过扩展后的不同比特位进行区别，具体为： In this case, most of the steps are the same as in the previous embodiments, and there is a difference in the third step. In the third step of the embodiment, the manner in which the eNB sends the transmission scheme and the feedback mode to the UE through the PDCCH is no longer set by the switch bit in the DCI format 0, but is differentiated by the extended different bits. , Specifically:

( 1 ) eNB在 DCI format 0 中用 CQI request 的最低位表示反馈信道。例如，根据是否在 PUSCH上进行反馈将 DCI format 0中的 CQI request 标记为 0或 1 ,其中， 1表示 UE通过 PUSCH进行反馈， 0表示 UE通过 PUCCH 进行反馈。 (1) The eNB uses the lowest bit of the CQI request in DCI format 0 to represent the feedback channel. For example, the CQI request in the DCI format 0 is marked as 0 or 1 according to whether feedback is performed on the PUSCH, where 1 indicates that the UE performs feedback through the PUSCH, and 0 indicates that the UE performs feedback through the PUCCH.

( 2 ) eNB在 DCI format 0 中用 CQI request的其他位来指示传输方案或者反馈类型，用法和开关位相同，在此不再赘述。如图 11所示，本发明实施例提出了另一种传输方案和 /或反馈模式的配置方法，通过应用本方法， eNB可以隐式的配置 UE的传输方案和 /或反馈模式。 (2) The eNB uses the other bits of the CQI request in the DCI format 0 to indicate the transmission scheme or the feedback type. The usage and the switch bits are the same, and are not described here. As shown in FIG. 11, the embodiment of the present invention provides another method for configuring a transmission scheme and/or a feedback mode. By applying the method, the eNB may implicitly configure a transmission scheme and/or a feedback mode of the UE.

以 eNB配置 UE在 PUSCH上进行周期的 CQL^馈为例，本方法具体包括以下步骤： For example, the eNB configures the UE to perform periodic CQL feed on the PUSCH. The method includes the following steps:

步骤 S1101、 eNB通过多条 RRC通知 UE进行周期的 CQLh>¾所对应的资源索引、配置索引和 CQI格式等配置信息所对应的不同的反馈模式。 Step S1101: The eNB notifies the UE to perform different feedback modes corresponding to the configuration information such as the resource index, the configuration index, and the CQI format corresponding to the CQLh>3⁄4 by the RRC.

步骤 S1102、 eNB选择是否使用 CoMP的传输方案，如果使用 CoMP的传输方案， eNB进一步确定 UE采用哪种传输方案。 Step S1102: The eNB selects whether to use the transmission scheme of the CoMP. If the transmission scheme of the CoMP is used, the eNB further determines which transmission scheme the UE adopts.

步骤 S 1103, eNB通过 PDCCH向 UE发送隐式的传输方案和反馈模式的设定。 Step S1103: The eNB sends an implicit transmission scheme and a feedback mode setting to the UE through the PDCCH.

与前述实施例相类似的，由于在步骤 S1101中已经通过 RRC信令通知 UE采用周期的 CQL^馈模式，所以本步骤中进一步在 PDCCH中发送 DCI format 0指示 UE在周期的 CQ 馈模式中所采用的反馈信道。 Similar to the foregoing embodiment, since the UE has been notified by the RRC signaling in step S1101 to adopt the periodic CQL feed mode, the DCI format 0 is further transmitted in the PDCCH in this step to indicate that the UE is in the periodic CQ feed mode. The feedback channel used.

进一步的，进行传输方案和反馈模式的隐式配置，具体包括以下几种方式： Further, the implicit configuration of the transmission scheme and the feedback mode includes the following methods:

方式一、 eNB设置 I_MCS = 29 (表示通知的 MCS的值为 29 ) , N_PRB < 4 时， UE在 PUSCH中没有数据传输，传输的全部为反馈的控制信息，此种情况对应反馈类型 A; eNB设置 I_MCS = 29 , 5 < N_PRB < N_p ^c^ (例如， N^ = 12 ) , UE在 PUSCH中没有数据传输，传输的全部为反馈的控制信息，此种情况对应反馈类型不同的反馈类型可以对应不同的传输方案。 Mode 1: The eNB sets I _MCS = 29 (indicating that the notified MCS value is 29), N _PRB < 4 At the time, the UE has no data transmission in the PUSCH, and all of the transmissions are feedback control information, which corresponds to the feedback type A; the eNB sets I _MCS = 29, 5 < N _PRB < N _p ^c ^ (for example, N^ = 12 The UE has no data transmission in the PUSCH, and all of the transmissions are feedback control information. In this case, the feedback types with different feedback types may correspond to different transmission schemes.

方式二、 eNB设置 N_PRB≤4 (在不同传输方案对应传输内容都较小）时，设置 I_MCS = ²⁹ , UE在 PUSCH中没有数据传输，传输的全部为反馈的控制信息，对应反馈类型 A; eNB设置 N_PRB≤ 4时， I_MCS = 30 , UE在 PUSCH 中没有数据传输，传输的全部为反馈的控制信息，对应反馈类型 B。 Manner 2: The eNB sets N _PRB ≤ 4 (when the transmission content of different transmission schemes is small), setting I _MCS = ²⁹ , the UE has no data transmission in the PUSCH, and all the transmissions are feedback control information, corresponding to the feedback type A. When the eNB sets N _PRB ≤ 4, I _MCS = 30, the UE has no data transmission in the PUSCH, and all the transmissions are feedback control information, corresponding to the feedback type B.

方式三、 eNB设置不同的 RNTI, A-RNTI对应反馈类型 A或者传输方案 A, B-RNTI对应反馈类型 B或者传输方案 B。 Manner 3: The eNB sets different RNTIs, the A-RNTI corresponds to the feedback type A or the transmission scheme A, and the B-RNTI corresponds to the feedback type B or the transmission scheme B.

在具体的应用场景中，具体采用上述的哪一种方式进行隐式设置并不影响本发明的保护范围。 In a specific application scenario, which one of the above methods is used for implicit setting does not affect the protection scope of the present invention.

步骤 S1104、 UE通过隐式指示的反馈类型或者传输方案和对应的 RRC信令在 PUSCH中反馈满足传输方案的反馈内容。 Step S1104: The UE feeds back the feedback content that satisfies the transmission scheme in the PUSCH by using the implicitly indicated feedback type or the transmission scheme and the corresponding RRC signaling.

步骤 S1105、 eNB接收 UE所反馈的当前传输方案的反馈内容。 Step S1105: The eNB receives the feedback content of the current transmission scheme fed back by the UE.

步骤 S1106、当 eNB参考当前传输方案的反馈内容，认为需要切换传输方案，将要求 UE反馈新的传输方案的反馈内容，并在收到相应的反馈内容后切换到新的传输方案。 Step S1106: When the eNB refers to the feedback content of the current transmission scheme, it is considered that the handover scheme needs to be switched, and the UE is required to feed back the feedback content of the new transmission scheme, and then switches to the new transmission scheme after receiving the corresponding feedback content.

对于第二种方式，可单独增加一条 RRC信令来指示长周期的反馈，无论切换到哪种短周期反馈，当到达长周期反馈的时间点时， UE都按照这条 RRC信令的配置进行长周期反馈。其中，该 RRC信令中的配置信息可以用开关位指示，也可作为缺省配置。 For the second mode, a single RRC signaling may be added to indicate long-term feedback. Regardless of which short-cycle feedback is switched, when the time of the long-cycle feedback is reached, the UE performs the RRC signaling configuration. Long cycle feedback. Wherein, the configuration information in the RRC signaling It can be indicated by a switch bit or as a default configuration.

通过应用本发明的技术方案，可以实现不同的 CoMP传输方案对应不同的反馈模式，能更好的节省反馈资源，并且用物理层控制信道的设置开关的方法相对于原来的 RRC信令通知能够更快的切换传输方案和反馈模式。如图 12所示，本发明实施例提出了另一种传输方案和 /或反馈模式的配置方法，通过应用本方法， eNB可以使用隐式和显式混合的方式配置 UE的传输方案和 /或反馈模式。 By applying the technical solution of the present invention, different CoMP transmission schemes can be implemented corresponding to different feedback modes, which can better save feedback resources, and the method of setting switches of the physical layer control channel can be more advanced than the original RRC signaling notification. Fast switching transmission scheme and feedback mode. As shown in FIG. 12, the embodiment of the present invention provides another configuration scheme of a transmission scheme and/or a feedback mode. By applying the method, an eNB may configure a transmission scheme of a UE by using an implicit and explicit hybrid manner. Feedback mode.

步骤 S 1201、 eNB通过多条 RRC通知 UE进行周期的 CQI上报所对应的资源索引、配置索引和 CQI格式等配置信息所对应的不同的反馈模式。 Step S1201: The eNB notifies the UE to perform different feedback modes corresponding to the configuration information such as the resource index, the configuration index, and the CQI format corresponding to the periodic CQI reporting by using multiple RRCs.

步骤 S1202、 eNB选择是否使用 CoMP的传输方案，如果使用 CoMP的传输方案， eNB进一步确定 UE采用哪种传输方案。 Step S1202: The eNB selects whether to use the transmission scheme of the CoMP. If the transmission scheme of the CoMP is used, the eNB further determines which transmission scheme the UE adopts.

步骤 S 1203、 eNB通过 PDCCH向 UE发送通过隐式和显式混合的方式所设置的传输方案和反馈模式的设定。 Step S1203: The eNB sends, by using a PDCCH, a setting of a transmission scheme and a feedback mode set by implicit and explicit mixing to the UE.

与前述实施例相类似的，由于在步骤 S1201中已经通过 RRC信令通知 UE采用周期的 CQL^馈模式，所以本步骤中进一步在 PDCCH中发送 DCI format 0指示 UE在周期的 CQ 馈模式中所采用的反馈信道。 Similar to the foregoing embodiment, since the UE has been notified by the RRC signaling in step S1201 to adopt the periodic CQL feed mode, the DCI format 0 is further transmitted in the PDCCH in this step to indicate that the UE is in the CQ feed mode of the cycle. The feedback channel used.

另一方面， eNB在 DCI format 0 中用开关位指示传输方案，为了尽量减少比特位的扩展，同样可以采用上述表 2所示的形式以及表 3所示的更加细化的形式表示传输方案。 On the other hand, the eNB indicates the transmission scheme by using switch bits in DCI format 0. In order to minimize the expansion of the bits, the transmission scheme can also be expressed in the form shown in Table 2 above and in the more refined form shown in Table 3.

在本实施例中，假设 eNB在 DCI format 0 中用开关位所指示的传输方案为传输方案 A。 In this embodiment, it is assumed that the transmission scheme indicated by the eNB in the DCI format 0 by the switch bit is the transmission scheme A.

进一步的，对应上述的传输方案进行反馈模式的隐式配置，具体包括以下几种方式： Further, the implicit configuration of the feedback mode is performed corresponding to the foregoing transmission scheme, and the specific package is Including the following ways:

In the feedback type A; the eNB sets I _MCS = ² 9 , 5 ≤ N _PRB ≤ N _P ^C ^ (for example, N _P ^ = 12 ), the UE has no data transmission in the PUSCH, and all the transmissions are feedback control information, This case corresponds to feedback type B in transmission scheme A. If the transmission scheme indicated by the foregoing switch bit is the transmission scheme B, the two types of settings corresponding to the above two settings are respectively the two feedback types of the transmission scheme B.
