背景技术Background technique

随着通信技术发展，一些通信***可支持的终端类型越来越多，例如：支持手机、平板电脑、机器人等，以及还可以支持能力有限终端(reduced capability UE，RedCap UE)，如穿戴设备、工业传感器、视频监控设备等。然而，目前通信***中控制信令所包含的比特数较多，某一些终端，如RedCap UE由于覆盖能力受限，导致无法成功接收包含较大比特数的控制信令。也就是说，该控制信令可能无法满足一些终端的覆盖需求，导致控制信令的覆盖效果较差。With the development of communication technology, some communication systems can support more and more terminal types, such as mobile phones, tablets, robots, etc., as well as reduced-capability UE (RedCap UE), such as wearable devices, Industrial sensors, video surveillance equipment, etc. However, the control signaling in the current communication system contains a large number of bits, and certain terminals, such as RedCap UE, cannot successfully receive the control signaling containing a large number of bits due to the limited coverage capability. In other words, the control signaling may not meet the coverage requirements of some terminals, resulting in poor coverage of the control signaling.

请参见图2，图2是本申请实施例提供的一种控制信令获取方法的流程图，该方法应用于终端，如图2所示，包括以下步骤：Please refer to FIG. 2. FIG. 2 is a flowchart of a method for obtaining control signaling according to an embodiment of the present application. The method is applied to a terminal, as shown in FIG. 2, and includes the following steps:

步骤201、获取第一级控制信令，所述第一级控制信令携带基本控制信息。Step 201: Obtain first-level control signaling, where the first-level control signaling carries basic control information.

其中，上述获取第一级控制信令可以是接收网络侧设备发送的第一级控制信令，或者可以是依据协议规定获取第一级控制信令，即第一级控制信令为协议约定。如协议约定，第一级控制信令的下行控制信息(Downlink Control Information，DCI)格式(format)和/或DCI内容(content)。Wherein, acquiring the first-level control signaling may be receiving the first-level control signaling sent by the network-side device, or may be acquiring the first-level control signaling according to protocol provisions, that is, the first-level control signaling is a protocol agreement. As agreed in the agreement, the downlink control information (Downlink Control Information, DCI) format and/or DCI content of the first-level control signaling.

上述基本控制信息可以是用于信号接收与解调的必要信息，如数据解调的相关指示，或者可以是协议约定的控制信息中最基本或者最重要的一种或者多种控制信息。例如，基本控制信息为DCI格式标识、频域资源分配、调制与编码方式等。除了基本控制信息之外的其他控制信息，例如，时域资源分配等可以通过网络侧配置一个默认值或初始值。这样可以实现仅通过获取第一级控制信令终端就可解调调度信息。由于第一级控制信令携带基本控制信息，而不携带其他控制信息，这样可以降低第一级控制信令的比特数，以增强第一级控制信令的覆盖效果。The above-mentioned basic control information may be necessary information for signal reception and demodulation, such as related instructions for data demodulation, or may be one or more of the most basic or most important control information agreed by the protocol. For example, the basic control information is DCI format identification, frequency domain resource allocation, modulation and coding mode, etc. In addition to basic control information, other control information, such as time domain resource allocation, can be configured with a default value or initial value through the network side. In this way, it is possible to demodulate the scheduling information only by acquiring the first-level control signaling terminal. Since the first-level control signaling carries basic control information and does not carry other control information, the number of bits of the first-level control signaling can be reduced in this way to enhance the coverage effect of the first-level control signaling.

步骤202、获取第二级控制信令，所述第二级控制信令所携带的控制信息用于如下至少一项：Step 202: Acquire second-level control signaling, where the control information carried in the second-level control signaling is used for at least one of the following:

指示其他控制信息。Indicates other control information.

其中，上述获取第二级控制信令可以是接收网络侧设备发送的第二级控制信令，或者可以是依据协议规定获取第二级控制信令，即第二级控制信令为协议约定。Wherein, obtaining the second-level control signaling described above may be receiving the second-level control signaling sent by the network side device, or may be obtaining the second-level control signaling according to protocol provisions, that is, the second-level control signaling is a protocol agreement.

如，协议约定第二级控制信令的DCI format和/或DCI content；又如，第二级控制信令的媒体接入控制单元(Medium access control-control element，MAC CE)资源时频位置，逻辑信道标识(logical channel identity，LCID)以及MAC CE内容。For example, the agreement stipulates the DCI format and/or DCI content of the second-level control signaling; another example is the time-frequency location of the Medium access control-control element (MAC CE) resource of the second-level control signaling. Logical channel identity (LCID) and MAC CE content.

上述更新所述第一级控制信令携带的基本控制信息可以是，第二级控制信令携带的控制信息用于更新第一级控制信令中携带的基本控制信息的无线资源控制(Radio Resource Control，RRC)配置信息，且可以是更新所述第一级控制信令携带的基本控制信息中的全部或部分控制信息。The foregoing update of the basic control information carried in the first-level control signaling may be that the control information carried in the second-level control signaling is used to update the radio resource control of the basic control information carried in the first-level control signaling. Control, RRC) configuration information, and may be to update all or part of the control information in the basic control information carried in the first-level control signaling.

例如，第二级控制信息用于更新调制与编码方案的RRC配置表格。For example, the second-level control information is used to update the RRC configuration table of the modulation and coding scheme.

上述指示其他控制信息可以是，除了第一级信令中的基本控信息之外，通过第二级控制信息指示其他一个或者多个控制信息。The above-mentioned indicating other control information may be, in addition to the basic control information in the first-level signaling, indicating other one or more control information through the second-level control information.

例如，第二级控制信令携带的其他控制信息可以是时域分配、第二级控制信令的生效时延指示、冗余版本、HARQ进程号等。For example, other control information carried by the second-level control signaling may be time domain allocation, the effective delay indication of the second-level control signaling, redundancy version, HARQ process number, and so on.

又例如，第二级控制信令携带的控制信息可以是DCI format 1-1,0-1或者DCI format 1-0,0-0中除去第一级控制信令中所携带基本控制信息之外的其他控制信息。For another example, the control information carried in the second-level control signaling may be DCI format 1-1, 0-1 or DCI format 1-0, 0-0 except for the basic control information carried in the first-level control signaling Other control information.

需要说明的是，本申请实施例中，并不限定步骤201和步骤202的执行顺序，例如：如图2所示，先执行步骤201，再执行步骤202，或者步骤201和步骤202同时执行，或者先执行步骤202再执行步骤201.It should be noted that, in the embodiment of the present application, the execution order of step 201 and step 202 is not limited. For example, as shown in FIG. 2, step 201 is executed first, and then step 202 is executed, or step 201 and step 202 are executed at the same time. Or first perform step 202 and then perform step 201.

本申请实施例中，通过上述分级传输控制信令的步骤，可通过第一级控制信令携带基本控制信息，来降低控制信令的比特数，进而提高控制信令的覆盖效果。In the embodiment of the present application, through the above step of hierarchical transmission of control signaling, basic control information can be carried through the first level of control signaling to reduce the number of bits of control signaling, thereby improving the coverage effect of control signaling.

作为一种可选的实施方式，所述方法还包括：As an optional implementation manner, the method further includes:

依据所述第一级控制信令和/或所述第二级控制信令，执行信号接收与解调。According to the first level control signaling and/or the second level control signaling, signal reception and demodulation are performed.

其中，上述依据所述第一级控制信令和/或所述第二级控制信令，执行信号接收与解调可以包括：Wherein, the foregoing performing signal reception and demodulation according to the first level control signaling and/or the second level control signaling may include:

依据所述第一级控制信令和所述第二级控制信令，执行信号接收与解调；或者Perform signal reception and demodulation according to the first level control signaling and the second level control signaling; or

依据所述第一级控制信令，执行信号接收与解调；或者Perform signal reception and demodulation according to the first level control signaling; or

依据所述第二级控制信令，执行信号接收与解调。According to the second-level control signaling, signal reception and demodulation are performed.

上述依据所述第一级控制信令，执行信号接收与解调可以是，仅依据上述基本控制信息进行信号的接收与解调。例如：在一些场景中通过上述基本控制信息指示了信号的接收时频资源，从而在该接收时频资源上进行接收与解调。需要说明的是，该实施方式中，可以是在获取到第二级控制信令之前依据所述第一级控制信令，执行信号接收与解调，当然，对此不作出限定，例如：也可以获取到第二级控制信令之后，依据所述第一级控制信令，执行信号接收与解调。According to the first-level control signaling, the signal reception and demodulation may be performed by the signal reception and demodulation only according to the basic control information. For example, in some scenarios, the receiving time-frequency resource of the signal is indicated by the above-mentioned basic control information, so that reception and demodulation are performed on the receiving time-frequency resource.

例如：第二级控制信令的比特小于预设阈值的情况下，通过打孔的方式将第二DCI复用到PDSCH上，而在比特大于或者等于预设阈值的情况下通过速率匹配rate matching的方式将第二DCI复用到PDSCH上。Rate matching方式中可以将第二DCI映射在与PDSCH DMRS相邻符号(OFDM symbol)上。For example: when the bits of the second-level control signaling are less than the preset threshold, the second DCI is multiplexed onto the PDSCH by puncturing, and if the bits are greater than or equal to the preset threshold, rate matching is used. The second DCI is multiplexed onto the PDSCH. In the rate matching mode, the second DCI can be mapped on the adjacent symbol (OFDM symbol) of the PDSCH DMRS.

由于在生效后使用，这样可以保证终端与网络侧设备对第二级控制信令理解一致，以避免数据传输或解调错误。Since it is used after it takes effect, it can ensure that the terminal and the network-side device have the same understanding of the second-level control signaling, so as to avoid data transmission or demodulation errors.

另外，上述第二级控制信令的HARQ反馈资源可以是高层配置的，也可以是通过第一级控制信令的相关域指示的。In addition, the HARQ feedback resource of the second-level control signaling may be configured by a higher layer, or may be indicated by the relevant field of the first-level control signaling.

进一步的，在第二级控制信令为组公共控制信令的情况下，可以不支持第二级控制信令的HARQ反馈。Further, when the second-level control signaling is a group common control signaling, HARQ feedback of the second-level control signaling may not be supported.

如果连接M次未成功解调所述信号，则切换到默认搜索空间组上监听PDCCH，或者停止对所述第一级控制信令和/或所述第二级控制信令的获取。If the signal is not successfully demodulated for M connections, then switch to the default search space group to monitor the PDCCH, or stop acquiring the first-level control signaling and/or the second-level control signaling.

上述M的取值可以是网络侧配置或协议约定，或UE通过能力上报给基站的，如大于或者等于1的整数。The value of M may be configured by the network side or agreed by a protocol, or reported by the UE to the base station through capability, such as an integer greater than or equal to 1.

上述默认搜索空间组可以是网络侧配置或协议约定的。The above-mentioned default search space group may be configured on the network side or agreed upon by a protocol.

例如：终端连续4次解调或反馈上述第一级控制信令和/或第二级控制信令所调度的数据都为NACK，则切换到或者回退到默认搜索空间组或默认搜索空间集合上监听PDCCH。For example, if the terminal demodulates or feeds back the data scheduled by the above-mentioned first-level control signaling and/or second-level control signaling are NACK for 4 consecutive times, it will switch to or fall back to the default search space group or default search space set. Monitor the PDCCH.

另外，上述PDCCH可以是下行调度DCI或者上行调度DCI，如回退DCI(fallback DCI)，具体如DCI format 0_0,1_0。In addition, the above-mentioned PDCCH may be downlink scheduling DCI or uplink scheduling DCI, such as fallback DCI (fallback DCI), specifically, DCI format 0_0, 1_0.

该实施方式中，可以及时在默认搜索空间组上监听PDCCH，以使得终端在未成功解调所述调度数据的情况下，及时监听其他控制信令，以实现数据的解调。In this implementation manner, the PDCCH can be monitored on the default search space group in time, so that the terminal can monitor other control signaling in time when the scheduled data is not successfully demodulated to achieve data demodulation.

作为一种可选的实施方式，上述第一级控制信令包括如下至少一项：As an optional implementation manner, the foregoing first-level control signaling includes at least one of the following:

载波指示、时域资源分配指示、虚拟资源块VRB与物理资源块PRB的映射关系、冗余版本、HARQ进程号、下行分配指示、PDSCH反馈的PUCCH资源指示、PDSCH到HARQ反馈定时指示、物理资源块PRB绑定大小指示、速率匹配指示、DMRS初始化序列。Carrier indicator, time domain resource allocation indicator, virtual resource block VRB and physical resource block PRB mapping relationship, redundancy version, HARQ process number, downlink allocation indicator, PDSCH feedback PUCCH resource indicator, PDSCH to HARQ feedback timing indicator, physical resource Block PRB bundling size indication, rate matching indication, DMRS initialization sequence.

该实施方式中，可以实现对第一级控制信令进行扩展，具体可以由网络侧配置或者协议约定。In this implementation manner, the first-level control signaling can be extended, which can be specifically configured by the network side or agreed by a protocol.

作为一种可选的实施方式，在所述第一级控制信令调度下行传输的情况下，所述第二级控制信令所携带的控制信息包括如下至少一项：调制与编码方式指示、DCI格式标识、频域资源分配指示、新传数据指示；As an optional implementation manner, in the case that the first-level control signaling schedules downlink transmission, the control information carried in the second-level control signaling includes at least one of the following: modulation and coding mode indication, DCI format identification, frequency domain resource allocation indication, new transmission data indication;

或者，在所述第一级控制信令调度上行传输的情况下，所述第二级控制信令中的控制信息包括如下至少一项：调制与编码方式指示、DCI格式标识、频域资源分配指示、新传数据指示、上行共享信道UL-SCH指示和开环指示。Or, in the case that the first-level control signaling schedules uplink transmission, the control information in the second-level control signaling includes at least one of the following: modulation and coding mode indication, DCI format identifier, frequency domain resource allocation Indication, newly transmitted data indication, uplink shared channel UL-SCH indication and open loop indication.

该实施方式中，可以实现对第二级控制信令进行扩展。且第二级控制信令如果与第一级控制信令携带相同的控制信息时，第二级控制信令中携带的该控制信息可以是用于对第一级控制信令携带的该控制信息的更新。或者，第二级控制信令与第一级控制信令携带的控制信息不同。例如：第一级控制信令中携带的基本控制信息包括调制与编码方式指示，则第二级控制信令中携带的控制信息中不包括调制与编码方式指示。In this implementation manner, the second-level control signaling can be extended. And if the second-level control signaling carries the same control information as the first-level control signaling, the control information carried in the second-level control signaling may be used to carry the control information for the first-level control signaling Update. Or, the control information carried in the second level control signaling is different from the control information carried in the first level control signaling. For example, if the basic control information carried in the first level control signaling includes the modulation and coding mode indication, the control information carried in the second level control signaling does not include the modulation and coding mode indication.

作为一种可选的实施方式，本申请实施例中的基本控制信息中的调制与编码方式指示的可配置比特低于第一配置比特。As an optional implementation manner, the configurable bit indicated by the modulation and coding mode in the basic control information in the embodiment of the present application is lower than the first configuration bit.

其中，上述第一配置比特可以是协议规定的调制与编码方式指示的配置比特，如协议规定的调制与编码方式指示的配置比特为5比特，则上述本申请实施例中的基本控制信息中的调制与编码方式指示的可配置比特低于5比特。例如：针对一些终端只需要支持最低端的8种MCS，因此控制信令中的MCS只需要3比特指示。Wherein, the above-mentioned first configuration bit may be a configuration bit indicated by a modulation and coding mode specified by the protocol. For example, if the configuration bit indicated by a modulation and coding mode specified by the protocol is 5 bits, then the basic control information in the above-mentioned embodiment of the present application The configurable bits indicated by the modulation and coding method are less than 5 bits. For example, some terminals only need to support the lowest 8 types of MCS, so the MCS in the control signaling only needs 3 bits to indicate.

另外，上述基本控制信息中的调制与编码方式指示的可配置比特低于第一配置比特可以理解为，上述基本控制信息中的调制与编码方式指示是经过压缩的指示信息。In addition, if the configurable bit indicated by the modulation and coding mode in the basic control information is lower than the first configuration bit, it can be understood that the modulation and coding mode indication in the basic control information is compressed indication information.

作为一种可选的实施方式，本申请实施例中的基本控制信息中的频域资源分配指示的最大可配置比特低于第二最大可配置比特。As an optional implementation manner, the maximum configurable bit of the frequency domain resource allocation indication in the basic control information in the embodiment of the present application is lower than the second maximum configurable bit.

其中，上述第二最大可配置比特可以是协议规定的频域资源分配指示的最大可配置比特，这样由于频域资源分配指示的最大可配置比特低于第二最大可配置比特，从而实现对频域资源分配指示的压缩，即降低频域资源分配指示的比特数。Wherein, the above-mentioned second maximum configurable bit may be the maximum configurable bit of the frequency domain resource allocation indication specified by the protocol. In this way, since the maximum configurable bit of the frequency domain resource allocation indication is lower than the second maximum configurable bit, frequency matching is achieved. The compression of the domain resource allocation indication is to reduce the number of bits of the frequency domain resource allocation indication.

通过上述调制与编码方式指示和频域资源分配指示可以进一步降低第一级控制信令的比特数。Through the above-mentioned modulation and coding mode indication and frequency domain resource allocation indication, the number of bits of the first-level control signaling can be further reduced.

作为一种可选的实施方式，上述第一级控制信令中的全部或部分基本控制信息采用联合编码。As an optional implementation manner, all or part of the basic control information in the above-mentioned first-level control signaling adopts joint coding.

例如：第一级控制信令的中的FDRA和MCS等可以联合编码；例如，对于边缘的终端的FDRA和MCS联合编码，一共用4比特表示16种预定义的FDRA和MCS组合等，当然，也可以扩展到更多域的更多组合，此处仅是举例说明。For example: FDRA and MCS in the first-level control signaling can be jointly coded; for example, for the joint coding of FDRA and MCS for edge terminals, a shared 4 bits represent 16 predefined combinations of FDRA and MCS, etc. Of course, It can also be extended to more combinations of more domains, here is just an example.

通过联合编码可以进一步降低第一级控制信令的比特数。Through joint coding, the number of bits of the first-level control signaling can be further reduced.

进一步的，上述基本控制信息还可以包括切换指示，该切换指示用于终端接收目标控制信令，并停止接收所述上述第一级控制信令和第二级控制信令，其中，所述目标控制信令为未分级的控制信令，或者可以称作正常的控制信令。Further, the above-mentioned basic control information may also include a handover indication, which is used by the terminal to receive target control signaling and stop receiving the above-mentioned first-level control signaling and second-level control signaling, wherein the target The control signaling is unclassified control signaling, or can be called normal control signaling.

例如：上述第一DCI还可以有指示DCI format切换的比特，如小区边缘终端移动到小区中心时，该比特指示终端开始接收正常DCI格式(例如，DCI format 1-0 0-0 1-1 0-1)，不获取上述第一DCI和第二DCI。For example: the above-mentioned first DCI may also have a bit indicating DCI format switching. For example, when the cell edge terminal moves to the cell center, this bit indicates that the terminal starts to receive the normal DCI format (for example, DCI format 1-0 0-0 1-1 0 -1), do not acquire the above-mentioned first DCI and second DCI.

另外，本申请实施例中，可以将第一DCI和第二DCI的搜索空间与其他控制信令的搜索空间分成不同的搜索空间，因此，上述切换指示也可以指示搜索空间的切换。In addition, in the embodiment of the present application, the search spaces of the first DCI and the second DCI and the search spaces of other control signaling may be divided into different search spaces, therefore, the above switching instruction may also indicate the switching of the search space.

本申请实施例中，获取第一级控制信令，所述第一级控制信令携带基本控制信息；获取第二级控制信令，所述第二级控制信令所携带的控制信息用于如下至少一项：更新所述第一级控制信令携带的基本控制信息；指示其他控制信息。这样由于第一级控制信令携带的是基本控制信息，可降低控制信令的比特数，进而提高控制信令的覆盖效果。In the embodiment of this application, the first-level control signaling is acquired, and the first-level control signaling carries basic control information; the second-level control signaling is acquired, and the control information carried in the second-level control signaling is used for At least one of the following: update the basic control information carried in the first-level control signaling; indicate other control information. In this way, because the first-level control signaling carries basic control information, the number of bits of the control signaling can be reduced, thereby improving the coverage effect of the control signaling.

下面以通过多个实施例对本申请实施例提供的方法进行举例说明，可以包括以下：The following uses multiple embodiments to illustrate the methods provided in the embodiments of the present application, which may include the following:

实施例一：Example one:

该实施例中，以第一级控制信令和第二级控制信令为两级DCI，且配置第二级控制信令的HARQ反馈机制进行举例说明：In this embodiment, the first level control signaling and the second level control signaling are two levels of DCI, and the HARQ feedback mechanism of the second level control signaling is configured for example:

网络侧配置给RedCap UE下行两级DCI，每级DCI各自的域如下。且两级DCI分别承载在网络所配置的搜索空间(Search Space，SS)内，如图6所示，终端被配置在SS1中检测第一DCI，在SS2中检测第二DCI。终端由第一DCI中的指示来判断是否检测第二DCI。The network side configures the RedCap UE to downlink two levels of DCI, and the respective domains of each level of DCI are as follows. In addition, the two levels of DCI are respectively carried in a search space (Search Space, SS) configured by the network. As shown in FIG. 6, the terminal is configured to detect the first DCI in SS1 and detect the second DCI in SS2. The terminal judges whether to detect the second DCI according to the indication in the first DCI.

其中，第一DCI可以为UE specific DCI，包括如下至少一项：Wherein, the first DCI may be UE-specific DCI, including at least one of the following:

DCI格式标识；DCI format identification;

频域资源分配指示；Frequency domain resource allocation indication;

新传数据指示；Newly transmitted data instructions;

用于指示是否检测所述第二级控制信令的指示域；An indication field used to indicate whether to detect the second level control signaling;

用于检测和/或解调所述第二级控制信令的指示域。An indication field used to detect and/or demodulate the second-level control signaling.

其中，检测所述第二级控制信令的指示域可以通过1比特来指示是否检测第二级控制信令的指示域，如‘0’表示不需要检测，‘1’表示需要检测。Wherein, the indicator field for detecting the second-level control signaling may use 1 bit to indicate whether to detect the indicator field of the second-level control signaling, for example, '0' indicates that detection is not required, and '1' indicates that detection is required.

用于检测和/或解调所述第二级控制信令的指示域可以包括解调第二级控制信息所需信息的指示域，如2比特，指示域包含参数：AL和CCE起始index(联合编码)。RRC配置组合如下：‘00’表示：AL起始index为4，CCE起始index为2(AL,CCE start index＝4,2)；‘01’表示：AL,CCE start index＝4,6；‘10’表示：AL,CCE start index＝8,24；‘11’表示：AL,CCE start index＝8,32。The indicator field used to detect and/or demodulate the second-level control signaling may include an indicator field of information required to demodulate the second-level control information, such as 2 bits. The indicator field includes parameters: AL and CCE start index (Joint coding). The RRC configuration combination is as follows: '00' means: AL start index is 4, CCE start index is 2 (AL, CCE start index = 4, 2); '01' means: AL, CCE start index = 4, 6; '10' means: AL,CCE start index=8,24; '11' means: AL,CCE start index=8,32.

第二DCI可以为UE specific DCI由PDCCH进行传输，可以包括如下至少一项：The second DCI may be UE-specific DCI transmitted by the PDCCH, and may include at least one of the following:

第二级控制信令的生效时延指示、载波指示、时域资源分配指示、虚拟资源块VRB到物理资源块PRB的映射关系、冗余版本、HARQ进程号、下行分配索引、被调度的物理上行控制信道PUCCH的发射功率控制TPC命令、PUCCH资源指示、PDSCH到HARQ反馈定时指示、物理资源块PRB绑定大小指示、速率匹配指示、零功率ZP信道状态指示参考信号CSI-RS触发、天线端口、传输配置指示TCI、探测参考信号SRS请求、DMRS序列初始化、带宽部分BWP指示、辅小区休眠指示、传输块2的调制与编码方式、传输块2的新传数据指示、传输块2的冗余版本、码块组CBG传输指示、CBG刷新指示、物理层PHY优先级标识。The effective delay indicator of the second level control signaling, carrier indicator, time domain resource allocation indicator, virtual resource block VRB to physical resource block PRB mapping relationship, redundancy version, HARQ process number, downlink allocation index, scheduled physical Uplink control channel PUCCH transmit power control TPC command, PUCCH resource indicator, PDSCH to HARQ feedback timing indicator, physical resource block PRB bundling size indicator, rate matching indicator, zero power ZP channel state indicator reference signal CSI-RS trigger, antenna port , Transmission configuration indication TCI, sounding reference signal SRS request, DMRS sequence initialization, bandwidth part BWP indication, secondary cell dormancy indication, transmission block 2 modulation and coding mode, transmission block 2 new transmission data indication, transmission block 2 redundancy Version, code block group CBG transmission indication, CBG refresh indication, physical layer PHY priority identification.

其中，终端测两级DCI的可以包括如下两种方式：Among them, the two-level DCI measurement of the terminal can include the following two methods:

一、根据第一DCI的指示，终端不需要检测第二级控制信令。如图6所示，第一个第一DCI指示不需要检测第二DCI，此时终端根据第一DCI的指示以及当前生效的第二DCI(上一个检测到的第二DCI)的指示来解调数据。1. According to the instruction of the first DCI, the terminal does not need to detect the second level control signaling. As shown in Figure 6, the first first DCI indicates that the second DCI does not need to be detected. At this time, the terminal resolves it according to the first DCI indication and the currently effective second DCI (the last detected second DCI) indication. Tune data.

二、根据第一DCI的指示，最后两个域的指示为‘1’终端需要检测第二DCI，‘01’表示第二DCI的AL和CCE start index为4,6。如图6所示，终端通过盲检第二个第一DCI，并根据第一DCI的指示检测第二DCI。但由于第二DCI生效时延为在第二DCI发送完ACK后的下一个时隙生效。因此，本次PDSCH(即第二个PDSCH)依旧根据第二个第一DCI跟前一个第二DCI来解调。直到完成第二DCI的HARQ反馈后，该第二DCI生效。如图6所示，第三个和第四个PDSCH是根据第一DCI跟生效后的第二DCI来解调的。2. According to the indication of the first DCI, the indication of the last two fields is '1' that the terminal needs to detect the second DCI, and '01' indicates that the AL and CCE start index of the second DCI are 4,6. As shown in FIG. 6, the terminal blindly detects the second first DCI, and detects the second DCI according to the indication of the first DCI. However, because the second DCI valid time delay is valid in the next time slot after the second DCI sends the ACK. Therefore, this PDSCH (ie, the second PDSCH) is still demodulated based on the second first DCI and the previous second DCI. Until the HARQ feedback of the second DCI is completed, the second DCI takes effect. As shown in FIG. 6, the third and fourth PDSCHs are demodulated based on the first DCI and the second DCI after taking effect.

进一步的，第二DCI可以仅支持反馈ACK，且在第二子码本中反馈。Further, the second DCI may only support ACK feedback, and the feedback is in the second sub-codebook.

如果终端连续N次解调两级DCI调度的数据都为NACK，则切换到/回退到搜索空间组1上监听下行调度DCI format1-0/0-0。If the terminal continuously demodulates the data of the two levels of DCI scheduling for N times, it will switch to/fall back to search space group 1 to monitor the downlink scheduling DCI format 1-0/0-0.

实施例2：Example 2:

该实施例中，以第二级控制信令为MAC CE，MAC CE生效时间＝3slots。不支持第二级控制信令单独的HARQ反馈，且MAC CE为UE specific配置进行举例说明：In this embodiment, the second-level control signaling is MAC CE, and the effective time of MAC CE = 3 slots. Separate HARQ feedback for level 2 control signaling is not supported, and MAC CE is UE-specific configuration for example:

网络配置给RedCap UE下行两级DCI，每级DCI各自的field如下。The network configures RedCap UE to downlink two levels of DCI, and the respective fields of each level of DCI are as follows.

第一DCI包括如下至少一项：The first DCI includes at least one of the following:

调制与编码方式指示、控制信息DCI格式标识、频域资源分配指示、新传数据指示。Modulation and coding mode indication, control information DCI format identification, frequency domain resource allocation indication, new transmission data indication.

第二级控制信令为MAC CE，该MAC CE承载多个子MAC CE，分别携带激活相关控制信息的指示，具体包括如下至少一项：The second level of control signaling is the MAC CE. The MAC CE carries multiple sub-MAC CEs and respectively carries instructions for activating related control information, which specifically includes at least one of the following:

其中，上述多个子MAC CE中以(TDRA)MAC CE为例：Among the above multiple sub-MAC CEs, (TDRA) MAC CE is taken as an example:

RRC配置了16个TDRA列表，通过TDRA MAC CE来动态指示其中一个(也可以激活多个)，定义TDRA MAC CE及其对应的LCID和MAC CE format。具体如下：RRC is configured with 16 TDRA lists, one of them is dynamically indicated through TDRA MAC CE (multiple can also be activated), and TDRA MAC CE and its corresponding LCID and MAC CE format are defined. details as follows:

特定终端的PDCCH MAC CE的时域资源分配由带LCID的MAC子头标识，该MAC子头固定为8比特，字段如图7所示。The time domain resource allocation of the PDCCH MAC CE of a specific terminal is identified by the MAC subheader with LCID. The MAC subheader is fixed to 8 bits, and the fields are shown in FIG. 7.

如图8所示，TDRA行ID(TDRA row ID):此字段指示由TDRA行ID标识的TDRA行ID，该字段的长度为4位。As shown in Figure 8, TDRA row ID (TDRA row ID): This field indicates the TDRA row ID identified by the TDRA row ID, and the length of this field is 4 bits.

其中，R表示预留位，可以为0比特。Among them, R represents a reserved bit, which can be 0 bits.

此外，该TDRA MAC CE的LCID取值如下表所示：In addition, the LCID value of the TDRA MAC CE is shown in the following table:

码点或者索引(Codepoint/Index)Codepoint or Index (Codepoint/Index)	LCID值LCID value
6464	TDRA MAC CETDRA MAC CE

进一步的，上述TDRA MAC CE可以是固定大小的，也可以是可变大小的。Further, the aforementioned TDRA MAC CE may be of a fixed size, or may be of a variable size.

其中，上述第二控制信令中剩余的MAC CE的设计类似，都可以如上TDRA MAC CE来设计与定义。Among them, the design of the remaining MAC CE in the above second control signaling is similar, and can be designed and defined as the above TDRA MAC CE.

另外，上述第一DCI可以承载在网络所配置的搜索空间内，如图9所示，被配置在SS1中检测第一DCI。第二级控制信信令由第一DCI动态调度(具体时域位置)，如图9所示第二级控制信信令承载在PDSCH信道中传输。终端通过解码PDSCH，并根据MAC子头中的LCID标识来判断是否有第二级控制信信令。第二级控制信信令的生效时延为3slots。在生效之前，终端根据第一DCI和前一个第二级控制信信令的指示来解调数据。In addition, the above-mentioned first DCI may be carried in a search space configured by the network. As shown in FIG. 9, it is configured to detect the first DCI in SS1. The second level control signal signaling is dynamically scheduled by the first DCI (specific time domain location). As shown in FIG. 9, the second level control signal signaling is carried in the PDSCH channel for transmission. The terminal determines whether there is second-level control letter signaling by decoding the PDSCH and according to the LCID identifier in the MAC subheader. The effective delay of the second-level control signal signaling is 3 slots. Before taking effect, the terminal demodulates the data according to the instructions of the first DCI and the previous second-level control signal signaling.

终端检测两级控制信令可以包括如下两种方式：The two-level control signaling for terminal detection can include the following two methods:

一、终端根据第一个第一DCI的指示以及当前生效的第二级控制信信令(上一个检测到的级控制信信令)的指示来解调数据。1. The terminal demodulates the data according to the indication of the first first DCI and the indication of the currently effective second level control signal signaling (the last detected level control signal signaling).

二、终端检测第二个第一DCI获取PDSCH，通过解调获得级控制信信令相关控制信息。在该级控制信信令生效后，UE会根据检测的第一DCI和该级控制信信令来解调数据，如最后两个PDSCH。2. The terminal detects the second first DCI to obtain the PDSCH, and obtains control information related to the level control signal signaling through demodulation. After this level of control signal signaling takes effect, the UE will demodulate data according to the detected first DCI and this level of control signal signaling, such as the last two PDSCHs.

需要说明的是，本申请实施例中，第二级控制信令为MAC CE的情况下，MAC CE可以采用如下设计：It should be noted that in the embodiment of this application, when the second-level control signaling is the MAC CE, the MAC CE may adopt the following design:

一、MAC CE为UE specific的。一个MAC CE中包括多个控制信息，可以如图10所示：1. MAC CE is UE specific. A MAC CE includes multiple control information, as shown in Figure 10:

二、MAC CE为group common的，一个MAC CE中包括多个终端的相关控制信息，可以如图11所示。2. MAC CE is group common, and one MAC CE includes related control information of multiple terminals, as shown in Figure 11.

需要说明的是，本申请实施例中第二级控制信令为MAC CE时，本申请实施例中，对MAC CE的格式不作限定，例如：也可以设计成与随机接入响应(Random Access Response，RAR)的串行MAC PDU，例如：如图12所示。It should be noted that when the second-level control signaling in the embodiment of this application is MAC CE, in the embodiment of this application, the format of MAC CE is not limited. For example, it can also be designed as a random access response (Random Access Response). , RAR) serial MAC PDU, for example: as shown in Figure 12.

本申请实施例中，引入两级DCI的方案，第一级控制信令传输必要的基本控制信息(比特数非常少)，第二级控制信令传输更精细的控制信息。终端在大多数情况下仅需要接收第一级控制信令即可解调数据或者发送数据，从而能够弥补由于RedCap UE能力限制而导致下行PDCCH的覆盖不够等缺点。同时第二级控制信令的设计也解决了网络调度受限等问题。In the embodiment of the present application, a two-level DCI solution is introduced. The first-level control signaling transmits necessary basic control information (the number of bits is very small), and the second-level control signaling transmits finer control information. In most cases, the terminal only needs to receive the first-level control signaling to demodulate or send data, which can make up for the shortcomings of insufficient downlink PDCCH coverage due to RedCap UE capability limitations. At the same time, the design of the second-level control signaling also solves the problems of limited network scheduling.
