Description

一种混合自动重传反馈方法、装置及存储介质A hybrid automatic retransmission feedback method, device and storage medium 技术领域Technical Field

本公开涉及通信技术领域，尤其涉及一种混合自动重传反馈方法、装置及存储介质。The present disclosure relates to the field of communication technology, and in particular to a hybrid automatic repeat request feedback method, device and storage medium.

背景技术Background technique

目前，网络控制中继器(network controlled repeater，NCR)可以以低成本的方式提高系统覆盖。其中，NCR可以包括两部分，即移动终端(mobile termination，MT)部分和转发(forwarding，Fwd)部分。其中，MT部分可以用来接收基站发送的控制命令。控制命令可以用于控制Fwd部分的行为，例如波束指示方向、转发的开启和关闭等。Currently, network controlled repeaters (NCRs) can improve system coverage in a low-cost way. NCRs can include two parts, namely the mobile termination (MT) part and the forwarding (Fwd) part. The MT part can be used to receive control commands sent by the base station. The control commands can be used to control the behavior of the Fwd part, such as beam indication direction, forwarding on and off, etc.

NCR可以接收来自基站的无线资源控制(radio resource control，RRC)信令、媒体接入控制元素(medium access control control element，MAC CE)信令和动态的下行控制信息(downlink control information，DCI)信令。其中，RRC信令和MAC CE信令一般在物理下行共享信道(physical downlink shared channel，PDSCH)中进行传输。而三代合作伙伴计划(3rd generation partnership project，3GPP)也允许了针对PDSCH进行混合自动重传请求(hybrid automatic repeat-request，HARQ)的反馈。其中HARQ的反馈包括确认(acknowledgement，ACK)反馈和/或否定确认(negative acknowledgement，NACK)反馈。NCR can receive radio resource control (RRC) signaling, medium access control element (MAC CE) signaling and dynamic downlink control information (DCI) signaling from the base station. Among them, RRC signaling and MAC CE signaling are generally transmitted in the physical downlink shared channel (PDSCH). The 3rd generation partnership project (3GPP) also allows hybrid automatic repeat-request (HARQ) feedback for PDSCH. Among them, HARQ feedback includes acknowledgment (ACK) feedback and/or negative acknowledgment (NACK) feedback.

但是，针对承载了侧控制信息(side control information)的DCI或物理下行控制信道(physical downlink control channel，PDCCH)上如何进行反馈，目前并未涉及，因此，如何对承载侧控制信息的DCI或PDCCH进行反馈，是需要解决的问题。However, how to provide feedback on the DCI or physical downlink control channel (PDCCH) that carries side control information has not been addressed yet. Therefore, how to provide feedback on the DCI or PDCCH that carries side control information is a problem that needs to be solved.

It should be understood that the embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the terminal.

本公开实施例中，网络设备110、中继设备120与终端130可以采用任意可行的无线通信技术以实现相互传输数据。其中，网络设备110向中继设备120发送数据所对应的传输通道称为下行信道(downlink，DL)，中继设备120向终端130发送数据所对应的传输通道也可称为DL。终端130向中继设备120发送数据所对应的传输通道称为上行信道 (uplink，UL)，中继设备120向网络设备110发送数据所对应的传输通道也可称为UL。可以理解的是，本公开实施例中所涉及的网络设备可以是基站。当然网络设备还可以是其它任意可能的网络设备，终端可以是任意可能的终端，本公开不作限定。In the embodiments of the present disclosure, the network device 110, the relay device 120 and the terminal 130 may adopt any feasible wireless communication technology to realize mutual data transmission. Among them, the transmission channel corresponding to the data sent by the network device 110 to the relay device 120 is called a downlink channel (downlink, DL), and the transmission channel corresponding to the data sent by the relay device 120 to the terminal 130 may also be called DL.

Of course, the network device may also be any other possible network device, and the terminal may be any possible terminal, which is not limited by the present disclosure.

目前，NCR可以以低成本的方式提高系统覆盖。其中，NCR可以包括两部分，即MT部分和Fwd部分。如图2所示出的通信场景示意图，可以看出，该通信场景200中，NCR 220中的MT部分221可以通过控制链路(control link)接收基站210发送的控制命令。其中，该控制命令可以用于控制Fwd部分222的行为。例如回程链路(backhual link)和接入链路(access link)上的行为。如，波束指示方向、转发的开启(ON)和关闭(OFF)等。NCR 220可以基于Fwd部分222的行为，向终端230转发基站210发送的数据。At present, NCR can improve system coverage in a low-cost manner. Among them, NCR can include two parts, namely the MT part and the Fwd part. As shown in the communication scenario schematic diagram of Figure 2, it can be seen that in the communication scenario 200, the MT part 221 in the NCR 220 can receive the control command sent by the base station 210 through the control link. Among them, the control command can be used to control the behavior of the Fwd part 222. For example, the behavior on the backhaul link and the access link. For example, the beam indication direction, forwarding on (ON) and off (OFF), etc. NCR 220 can forward the data sent by the base station 210 to the terminal 230 based on the behavior of the Fwd part 222.

在一些例子中，NCR的MT部分表示该NCR也可以看做是一种简易版的终端。也可以作为终端接收网络设备发送的命令，并进行相应操作。例如接收控制命令，并基于该控制命令控制自身作为中继时的一些转发行为，即控制Fwd部分的一些行为。。In some examples, the MT part of NCR indicates that the NCR can also be regarded as a simplified version of a terminal. It can also receive commands sent by network devices as a terminal and perform corresponding operations. For example, it receives control commands and controls some forwarding behaviors when it acts as a relay based on the control commands, that is, controls some behaviors of the Fwd part.

NCR可以接收来自基站的RRC信令、MAC CE信令和动态的DCI信令。其中，RRC信令和MAC CE信令一般在PDSCH中进行传输。而3GPP也允许了针对PDSCH进行HARQ的反馈。以此保证信令的正确接收，增强其鲁棒性。其中，HARQ的反馈可以包括ACK和/或NACK。但是对于承载侧控制信息的DCI或PDCCH上如何进行反馈，目前仍未达成一致。NCR can receive RRC signaling, MAC CE signaling and dynamic DCI signaling from the base station. Among them, RRC signaling and MAC CE signaling are generally transmitted in PDSCH. 3GPP also allows HARQ feedback for PDSCH. This ensures the correct reception of signaling and enhances its robustness. Among them, HARQ feedback can include ACK and/or NACK. However, there is still no consensus on how to provide feedback on DCI or PDCCH that carries control information on the bearer side.

在相关技术中，针对UE的一些特殊的DCI也存在HARQ反馈。比如，UE需要针对半静态调度(semi－persistent scheduling，SPS)释放(release)的DCI进行反馈。In related technologies, HARQ feedback also exists for some special DCIs of UE. For example, UE needs to provide feedback for DCI released by semi-persistent scheduling (SPS).

而PDCCH是否需要进行HARQ反馈，针对不同信令需要具体分析。比如没有调度PDSCH的PDCCH，如承载SPS失活(deactivation)的信令；又比如，对时延要求不高的信令，如承载SPS deactivation的信令；又比如，需要的可靠性高的信令，如承载统一(unified)传输配置指示(transmission configuration indication，TCI)指示(indication)。Whether PDCCH needs HARQ feedback requires specific analysis for different signaling. For example, PDCCH that does not schedule PDSCH, such as signaling that carries SPS deactivation; for example, signaling that does not require high latency, such as signaling that carries SPS deactivation; for example, signaling that requires high reliability, such as signaling that carries unified transmission configuration indication (TCI) indication.

同时，在侧控制信息中除了包括波束调整的信息，还有可以包括ON-OFF信息、功率控制(power control)信息、时分双工(time division duplex，TDD)信息等信息。其中，有些信息比如ON-OFF信息会对后续的中继转发行为造成影响，并且没有太高的时延要求。At the same time, in addition to the beam adjustment information, the side control information may also include ON-OFF information, power control information, time division duplex (TDD) information, etc. Among them, some information such as ON-OFF information will affect the subsequent relay forwarding behavior, and there is no high latency requirement.

因此，目前亟需一种可以针对不同信令能够支持不同反馈特性的方法。对于如何对包括侧控制信息的DCI或PDCCH进行反馈，是需要解决的问题。Therefore, a method that can support different feedback characteristics for different signaling is urgently needed. How to provide feedback for DCI or PDCCH including side control information is a problem that needs to be solved.

本公开通过DCI对包括侧控制信息的DCI进行HARQ反馈的指示，使得不同信令可以支持不同的反馈方式。进而保证相应信令的正确接收，提升通信系统的鲁棒性。The present disclosure uses DCI to indicate HARQ feedback on DCI including side control information, so that different signaling can support different feedback modes, thereby ensuring the correct reception of corresponding signaling and improving the robustness of the communication system.

图3是根据一示例性实施例示出的一种混合自动重传反馈方法流程图，如图3所示， 方法由中继设备执行。其中，中继设备可以是上述提到的NCR，方法可以包括以下步骤：FIG3 is a flow chart of a hybrid automatic repeat request feedback method according to an exemplary embodiment. As shown in FIG3 , the method is executed by a relay device. The relay device may be the NCR mentioned above, and the method may include the following steps:

在步骤S11中，接收网络设备发送的下行控制信息DCI。In step S11, downlink control information DCI sent by a network device is received.

在一些实施例中，中继设备可以接收网络设备发送的DCI。其中，该DCI包括侧控制信息，该DCI在PDCCH上进行传输。In some embodiments, the relay device may receive DCI sent by the network device, wherein the DCI includes side control information and the DCI is transmitted on the PDCCH.

例如，中继设备可以接收网络设备发送的包括侧控制信息的DCI。For example, the relay device may receive DCI including the side control information sent by the network device.

在步骤S12中，根据DCI确定是否向网络设备进行混合自动重传HARQ反馈。In step S12, it is determined whether to perform hybrid automatic repeat request (HARQ) feedback to the network device according to the DCI.

在一些实施例中，中继设备可以根据S11中接收到的DCI，确定是否向网络设备进行HARQ反馈。其中，该HARQ反馈表示中继设备对包括侧控制信息的DCI进行HARQ反馈。In some embodiments, the relay device may determine whether to perform HARQ feedback to the network device according to the DCI received in S11. The HARQ feedback indicates that the relay device performs HARQ feedback on the DCI including the side control information.

其中，是否向网络设备进行HARQ反馈，可以包括进行HARQ反馈以及不进行HARQ反馈。Whether to perform HARQ feedback to the network device may include performing HARQ feedback or not performing HARQ feedback.

可以理解，由于DCI在PDCCH上传输，因此对DCI进行HARQ反馈，也可以认为是对传输该DCI的PDCCH进行HARQ反馈。It can be understood that, since the DCI is transmitted on the PDCCH, performing HARQ feedback on the DCI can also be considered as performing HARQ feedback on the PDCCH that transmits the DCI.

本公开通过DCI对包括侧控制信息的DCI进行HARQ反馈的指示，使得不同信令可以支持不同的反馈方式。进而保证相应信令的正确接收，提升通信系统的鲁棒性。The present disclosure uses DCI to indicate HARQ feedback on DCI including side control information, so that different signaling can support different feedback modes, thereby ensuring the correct reception of corresponding signaling and improving the robustness of the communication system.

本公开实施例提供的混合自动重传反馈方法中，DCI包括HARQ反馈指示域；根据DCI确定是否向网络设备进行混合自动重传HARQ反馈，可以包括：根据HARQ反馈指示域确定是否向网络设备进行HARQ反馈。In the hybrid automatic repeat request feedback method provided by the embodiment of the present disclosure, the DCI includes a HARQ feedback indication field; determining whether to perform hybrid automatic repeat request HARQ feedback to the network device according to the DCI may include: determining whether to perform HARQ feedback to the network device according to the HARQ feedback indication field.

在一些实施例中，中继设备接收到网络设备发送的包括侧控制信息的DCI中，可以包括HARQ反馈指示域。该HARQ反馈指示域用于指示该中继设备是否向网络设备进行HARQ反馈。中继设备可以根据HARQ反馈指示域，确定是否向网络设备进行HARQ反馈。In some embodiments, the DCI including the side control information sent by the network device and received by the relay device may include a HARQ feedback indication field. The HARQ feedback indication field is used to indicate whether the relay device performs HARQ feedback to the network device. The relay device may determine whether to perform HARQ feedback to the network device based on the HARQ feedback indication field.

例如，HARQ反馈指示域可以指示中继设备向网络设备对包括侧控制信息的DCI进行HARQ反馈。或者，HARQ反馈指示域可以指示中继设备不向网络设备对包括侧控制信息的DCI进行HARQ反馈。For example, the HARQ feedback indication field may indicate that the relay device performs HARQ feedback on the DCI including the side control information to the network device. Alternatively, the HARQ feedback indication field may indicate that the relay device does not perform HARQ feedback on the DCI including the side control information to the network device.

例如，HARQ反馈可以包括HARQ-ACK或HARQ-NACK。For example, the HARQ feedback may include a HARQ-ACK or a HARQ-NACK.

本公开通过DCI中的HARQ反馈指示域，指示是否对包括侧控制信息的DCI进行HARQ反馈，使得不同信令可以支持不同的反馈方式。进而保证相应信令的正确接收，提升通信系统的鲁棒性。The present disclosure indicates whether to perform HARQ feedback on the DCI including the side control information through the HARQ feedback indication field in the DCI, so that different signaling can support different feedback modes, thereby ensuring the correct reception of the corresponding signaling and improving the robustness of the communication system.

本公开实施例提供的混合自动重传反馈方法中，根据HARQ反馈指示域确定是否向网络设备进行HARQ反馈，包括：HARQ反馈指示域为第一数值，根据第一数值对DCI进 行HARQ反馈。In the hybrid automatic repeat request feedback method provided by the embodiment of the present disclosure, whether to perform HARQ feedback to the network device is determined according to the HARQ feedback indication field, including: the HARQ feedback indication field is a first value, and HARQ feedback is performed on the DCI according to the first value.

在一些实施例中，HARQ反馈指示域可以为第一数值，在此情况中，HARQ反馈指示域的第一数值可以表示对包括侧控制信息的DCI进行HARQ反馈。In some embodiments, the HARQ feedback indication field may be a first value. In this case, the first value of the HARQ feedback indication field may indicate that HARQ feedback is performed on the DCI including the side control information.

例如，HARQ反馈指示域为第一数值，中继设备根据第一数值对包括侧控制信息的DCI进行HARQ-ACK反馈。For example, the HARQ feedback indication field is a first value, and the relay device performs HARQ-ACK feedback on the DCI including the side control information according to the first value.

又例如，HARQ反馈指示域为第一数值，中继设备根据第一数值对包括侧控制信息的DCI进行HARQ-NACK反馈。For another example, the HARQ feedback indication field is a first value, and the relay device performs HARQ-NACK feedback on the DCI including the side control information according to the first value.

可以理解，若包括侧控制信息的DCI对时延要求不高的情况下，可以对包括侧控制信息的DCI进行HARQ反馈。It can be understood that if the DCI including the side control information does not have a high requirement on the delay, HARQ feedback can be performed on the DCI including the side control information.

本公开通过HARQ反馈指示域为第一数值以指示包括侧控制信息的DCI进行HARQ反馈，使得不同信令可以支持不同的反馈方式。进而保证相应信令的正确接收，提升通信系统的鲁棒性。The present disclosure uses the HARQ feedback indication field as the first value to indicate that the DCI including the side control information performs HARQ feedback, so that different signaling can support different feedback modes, thereby ensuring the correct reception of the corresponding signaling and improving the robustness of the communication system.

本公开实施例提供的混合自动重传反馈方法中，根据HARQ反馈指示域确定是否向网络设备进行HARQ反馈，包括：HARQ反馈指示域为第二数值，根据第二数值对包括侧控制信息的DCI不进行HARQ反馈。In the hybrid automatic repeat request feedback method provided by the embodiment of the present disclosure, whether to perform HARQ feedback to the network device is determined according to the HARQ feedback indication field, including: the HARQ feedback indication field is a second value, and HARQ feedback is not performed on the DCI including the side control information according to the second value.

在一些实施例中，HARQ反馈指示域可以为第二数值，在此情况中，HARQ反馈指示域的第二数值可以表示对包括侧控制信息的DCI不进行HARQ反馈。In some embodiments, the HARQ feedback indication field may be a second value. In this case, the second value of the HARQ feedback indication field may indicate that no HARQ feedback is performed on the DCI including the side control information.

例如，HARQ反馈指示域为第二数值，中继设备根据第二数值对包括侧控制信息的DCI不进行HARQ-ACK反馈。For example, the HARQ feedback indication field is a second value, and the relay device does not perform HARQ-ACK feedback for the DCI including the side control information according to the second value.

又例如，HARQ反馈指示域为第二数值，中继设备根据第二数值对包括侧控制信息的DCI不进行HARQ-NACK反馈。For another example, the HARQ feedback indication field is a second value, and the relay device does not perform HARQ-NACK feedback for the DCI including the side control information according to the second value.

可以理解，若包括侧控制信息的DCI对时延要求高的情况下，可以不对包括侧控制信息的DCI进行HARQ反馈。It can be understood that if the DCI including the side control information has a high delay requirement, HARQ feedback may not be performed on the DCI including the side control information.

本公开通过HARQ反馈指示域为第二数值以指示包括侧控制信息的DCI不进行HARQ反馈，使得不同信令可以支持不同的反馈方式。进而保证相应信令的正确接收，提升通信系统的鲁棒性。The present disclosure uses the HARQ feedback indication field as the second value to indicate that the DCI including the side control information does not perform HARQ feedback, so that different signaling can support different feedback modes, thereby ensuring the correct reception of the corresponding signaling and improving the robustness of the communication system.

本公开实施例提供的混合自动重传反馈方法中，HARQ反馈包括以下任意一项：混合自动重传确认HARQ-ACK；混合自动重传否定确认HARQ-NACK。In the hybrid automatic repeat request feedback method provided in the embodiment of the present disclosure, the HARQ feedback includes any one of the following: a hybrid automatic repeat request confirmation HARQ-ACK; a hybrid automatic repeat request negative confirmation HARQ-NACK.

在一些实施例中，HARQ反馈可以是混合自动重传确认HARQ-ACK。In some embodiments, the HARQ feedback may be a Hybrid Automatic Repeat Request Acknowledgement HARQ-ACK.

例如，当中继设备正确解调侧控制信息时，可以向网络设备发送HARQ-ACK。For example, when the relay device correctly demodulates the side control information, it can send a HARQ-ACK to the network device.

在一些实施例中，HARQ反馈可以是混合自动重传否定确认HARQ-NACK。In some embodiments, the HARQ feedback may be a hybrid automatic repeat request negative acknowledgement HARQ-NACK.

例如，当中继设备没有正确解调侧控制信息时，可以向网络设备发送HARQ-NACK。For example, when the relay device fails to correctly demodulate the side control information, it may send a HARQ-NACK to the network device.

本公开可以支持多种HARQ的反馈信息，以适应多种通信场景。进而保证相应信令的正确接收，提升通信系统的鲁棒性。The present disclosure can support multiple HARQ feedback information to adapt to multiple communication scenarios, thereby ensuring the correct reception of corresponding signaling and improving the robustness of the communication system.

本公开实施例提供的混合自动重传反馈方法中，HARQ反馈指示域为专用信息位，专用信息位只用于指示是否进行HARQ反馈。In the hybrid automatic repeat request feedback method provided by the embodiment of the present disclosure, the HARQ feedback indication field is a dedicated information bit, and the dedicated information bit is only used to indicate whether to perform HARQ feedback.

在一些实施例中，HARQ反馈指示域可以是专用信息位，该专用信息位可以只用于指示是否对包括侧控制信息的DCI进行HARQ反馈。In some embodiments, the HARQ feedback indication field may be a dedicated information bit, which may be used only to indicate whether to perform HARQ feedback on the DCI including the side control information.

例如，可以在DCI中新增专用信息位，如HARQ反馈(feedback)使能(enable)/非使能(disable)信息位。For example, dedicated information bits may be added to the DCI, such as HARQ feedback enable/disable information bits.

如，当HARQ feedback enable/disable信息位为第一数值时，可以表示为enable，即指示中继设备需要对包括侧控制信息的DCI进行HARQ反馈。也可以理解为，指示中继设备需要对传输包括侧控制信息的DCI的PDCCH进行HARQ反馈。如，可以是发送HARQ-ACK或发送HARQ-NACK。For example, when the HARQ feedback enable/disable information bit is the first value, it can be represented as enable, indicating that the relay device needs to perform HARQ feedback on the DCI including the side control information. It can also be understood as indicating that the relay device needs to perform HARQ feedback on the PDCCH that transmits the DCI including the side control information. For example, it can be sending HARQ-ACK or sending HARQ-NACK.

又如，当HARQ feedback enable/disable信息位为第二数值时，可以表示为disable，即指示中继设备不需要对包括侧控制信息的DCI进行HARQ反馈。也可以理解为，指示中继设备不需要对传输包括侧控制信息的DCI的PDCCH进行HARQ反馈。如，可以不发送HARQ-ACK以及HARQ-NACK。For another example, when the HARQ feedback enable/disable information bit is the second value, it can be represented as disable, which indicates that the relay device does not need to perform HARQ feedback on the DCI including the side control information. It can also be understood as indicating that the relay device does not need to perform HARQ feedback on the PDCCH that transmits the DCI including the side control information. For example, HARQ-ACK and HARQ-NACK may not be sent.

例如，HARQ feedback enable/disable信息位可以是1比特(bit)的信息位，第一数值可以是1，第二数值可以是0。或者，第一数值可以是0，第二数值可以是1。本公开对第一数值、第二数据的具体数值不作限定。For example, the HARQ feedback enable/disable information bit may be a 1-bit information bit, the first value may be 1, and the second value may be 0. Alternatively, the first value may be 0, and the second value may be 1. The present disclosure does not limit the specific values of the first value and the second value.

本公开通过在DCI中新增专用于指示是否对包括侧控制信息的DCI进行HARQ反馈的专用信息位，使得不同信令可以支持不同的反馈方式。进而保证相应信令的正确接收，提升通信系统的鲁棒性。The present disclosure adds a dedicated information bit in DCI for indicating whether to perform HARQ feedback on the DCI including the side control information, so that different signaling can support different feedback modes, thereby ensuring the correct reception of the corresponding signaling and improving the robustness of the communication system.

本公开实施例提供的混合自动重传反馈方法中，HARQ反馈指示域为复用信息域，复用信息域用于联合指示是否进行HARQ反馈，以及用于指示反馈不同于HARQ反馈的其它信息。In the hybrid automatic repeat request feedback method provided by the embodiment of the present disclosure, the HARQ feedback indication field is a multiplexed information field, and the multiplexed information field is used to jointly indicate whether to perform HARQ feedback, and to indicate feedback of other information different from HARQ feedback.

在一些实施例中，HARQ反馈指示域可以是复用信息域，即DCI中已有的信息域。且该信息域已用于指示不同于上述HARQ反馈的其它信息。也就是说，HARQ反馈指示域可以复用DCI中已有的信息域，作为复用信息域。使得复用信息域可以用于联合指示是否对包括侧控制信息的DCI进行HARQ反馈，以及用于指示反馈不同于上述HARQ反馈的任意其它信息。In some embodiments, the HARQ feedback indication field may be a multiplexed information field, that is, an existing information field in the DCI. And the information field has been used to indicate other information different from the above HARQ feedback. In other words, the HARQ feedback indication field may reuse the existing information field in the DCI as the multiplexed information field. The multiplexed information field may be used to jointly indicate whether to perform HARQ feedback on the DCI including the side control information, and to indicate feedback of any other information different from the above HARQ feedback.

例如，HARQ反馈指示域可以复用HARQ过程(process)身份标识(identity document，ID)作为复用信息域进行指示。For example, the HARQ feedback indication field can reuse the HARQ process identity document (ID) as the multiplexed information field for indication.

如，当HARQ process ID为第一数值时，可以指示中继设备需要对包括侧控制信息的DCI进行HARQ反馈。也可以理解为，指示中继设备需要对传输包括侧控制信息的DCI的PDCCH进行HARQ反馈。如，可以发送HARQ-ACK或HARQ-NACK。For example, when the HARQ process ID is the first value, it can indicate that the relay device needs to perform HARQ feedback on the DCI including the side control information. It can also be understood as indicating that the relay device needs to perform HARQ feedback on the PDCCH that transmits the DCI including the side control information. For example, HARQ-ACK or HARQ-NACK can be sent.

又如，当HARQ process ID为第二数值时，可以指示中继设备不需要对包括侧控制信息的DCI进行HARQ反馈。也可以理解为，指示中继设备不需要对传输包括侧控制信息的DCI的PDCCH进行HARQ反馈。如，可以不发送HARQ-ACK以及HARQ-NACK。For another example, when the HARQ process ID is the second value, it can indicate that the relay device does not need to perform HARQ feedback on the DCI including the side control information. It can also be understood as indicating that the relay device does not need to perform HARQ feedback on the PDCCH that transmits the DCI including the side control information. For example, HARQ-ACK and HARQ-NACK may not be sent.

例如，HARQ process ID为第一数值可以是0，第二数值可以是非0。或者，第一数值可以是任意数值，第二数值可以是与第一数值不同的数值。本公开对第一数值、第二数据的具体数值不作限定。For example, the first value of the HARQ process ID may be 0, and the second value may be non-0. Alternatively, the first value may be any value, and the second value may be a value different from the first value. The present disclosure does not limit the specific values of the first value and the second value.

在一些实施例中，HARQ反馈指示域可以是对DCI中任意已有的信息域进行重新翻译，并作为复用信息域。以便用于联合指示是否进行HARQ反馈，以及不同于HARQ反馈的其它信息。In some embodiments, the HARQ feedback indication field may be a retranslation of any existing information field in the DCI and used as a multiplexed information field to jointly indicate whether to perform HARQ feedback and other information different from HARQ feedback.

其中，复用信息域可以在同一时刻同时指示是否进行HARQ反馈以及不同于HARQ反馈的其它信息。比如调制编码方式(modulation and coding scheme，MCS)域的最高比特位用于指示是否进行HARQ反馈，剩余的比特位用于指示调制编码方式。The multiplexed information field can simultaneously indicate whether to perform HARQ feedback and other information different from HARQ feedback at the same time. For example, the highest bit of the modulation and coding scheme (MCS) field is used to indicate whether to perform HARQ feedback, and the remaining bits are used to indicate the modulation and coding scheme.

又例如，复用信息域还可以在不同情况下指示是否进行HARQ反馈或者不同于HARQ反馈的其它信息。比如在特定情况下，如特定的无线网络临时标识(radio network temporary identity，RNTI)加扰方式1下，表示是否进行HARQ反馈，在特定的RNTI加扰方式2下，表示不同于HARQ反馈的其它信息。For another example, the multiplexing information field may also indicate whether to perform HARQ feedback or other information different from HARQ feedback in different situations. For example, in specific situations, such as a specific radio network temporary identity (RNTI) scrambling mode 1, it indicates whether to perform HARQ feedback, and in a specific RNTI scrambling mode 2, it indicates other information different from HARQ feedback.

本公开通过复用DCI中已有的信息域，以指示是否对包括侧控制信息的DCI进行HARQ反馈，使得不同信令可以支持不同的反馈方式。进而保证相应信令的正确接收，提升通信系统的鲁棒性。The present disclosure multiplexes the existing information field in DCI to indicate whether to perform HARQ feedback on the DCI including the side control information, so that different signaling can support different feedback modes, thereby ensuring the correct reception of the corresponding signaling and improving the robustness of the communication system.

本公开实施例提供的混合自动重传反馈方法中，图4是根据一示例性实施例示出的另一种混合自动重传反馈方法流程图。如图4所示，方法还可以包括以下步骤：In the hybrid automatic repeat request feedback method provided in the embodiment of the present disclosure, FIG4 is a flow chart of another hybrid automatic repeat request feedback method according to an exemplary embodiment. As shown in FIG4, the method may further include the following steps:

在步骤S21中，接收网络设备发送的无线资源控制RRC信令。In step S21, a radio resource control RRC signaling sent by a network device is received.

在一些实施例中，中继设备可以接收网络设备发送的RRC信令。该RRC信令可以用于指示HARQ反馈指示域内数值与是否进行HARQ反馈的对应关系。In some embodiments, the relay device may receive RRC signaling sent by the network device. The RRC signaling may be used to indicate the corresponding relationship between the value in the HARQ feedback indication field and whether to perform HARQ feedback.

例如，当HARQ反馈指示域为专用信息位时，RRC信令可以用于指示该专用信息位中第一数值和/或第二数值，与是否进行HARQ反馈的对应关系。如指示以下至少一种对 应关系：第一数值表示发送HARQ-ACK或HARQ-NACK；第一数值表示不发送HARQ-ACK和HARQ-NACK；第二数值表示发送HARQ-ACK或HARQ-NACK；第二数值表示不发送HARQ-ACK和HARQ-NACK。For example, when the HARQ feedback indication field is a dedicated information bit, the RRC signaling may be used to indicate the correspondence between the first value and/or the second value in the dedicated information bit and whether HARQ feedback is performed. For example, at least one of the following correspondences may be indicated: the first value indicates sending HARQ-ACK or HARQ-NACK; the first value indicates not sending HARQ-ACK and HARQ-NACK; the second value indicates sending HARQ-ACK or HARQ-NACK; the second value indicates not sending HARQ-ACK and HARQ-NACK.

又例如，当HARQ反馈指示域为复用信息域时，RRC信令可以用于指示该复用信息域中第一数值和/或第二数值，与是否进行HARQ反馈的对应关系。如指示以下至少一种对应关系：第一数值表示发送HARQ-ACK或HARQ-NACK；第一数值表示不发送HARQ-ACK和HARQ-NACK；第二数值表示发送HARQ-ACK或HARQ-NACK；第二数值表示不发送HARQ-ACK和HARQ-NACK。For another example, when the HARQ feedback indication field is a multiplexing information field, the RRC signaling may be used to indicate the correspondence between the first value and/or the second value in the multiplexing information field and whether HARQ feedback is performed. For example, at least one of the following correspondences is indicated: the first value indicates sending HARQ-ACK or HARQ-NACK; the first value indicates not sending HARQ-ACK and HARQ-NACK; the second value indicates sending HARQ-ACK or HARQ-NACK; the second value indicates not sending HARQ-ACK and HARQ-NACK.

本公开可以通过RRC指示HARQ反馈指示域内数值与是否进行HARQ反馈的对应关系，以便通过HARQ反馈指示域内数值指示是否对包括侧控制信息的DCI进行HARQ反馈，使得不同信令可以支持不同的反馈方式。进而保证相应信令的正确接收，提升通信系统的鲁棒性。The present disclosure can indicate the correspondence between the value in the HARQ feedback indication field and whether to perform HARQ feedback through RRC, so as to indicate whether to perform HARQ feedback on the DCI including the side control information through the value in the HARQ feedback indication field, so that different signaling can support different feedback modes, thereby ensuring the correct reception of the corresponding signaling and improving the robustness of the communication system.

本公开实施例提供的混合自动重传反馈方法中，基于预定义规则确定以下至少一种信息：HARQ反馈的时间；HARQ反馈的时频域资源；HARQ反馈的发送功率。In the hybrid automatic repeat request feedback method provided by the embodiment of the present disclosure, at least one of the following information is determined based on predefined rules: the time of HARQ feedback; the time-frequency domain resources of HARQ feedback; and the transmission power of HARQ feedback.

其中，在一些实施例中，为了降低HARQ指示相关的开销，可以通过预定义和/或预配置的方式，对HARQ反馈的时间、HARQ反馈的时频域资源和HARQ反馈的发送功率中的至少一项信息进行确定。In some embodiments, in order to reduce the overhead related to the HARQ indication, at least one of the information including the time of HARQ feedback, the time-frequency domain resources of HARQ feedback and the transmit power of HARQ feedback can be determined in a predefined and/or preconfigured manner.

在一些实施例中，可以通过预定义的方式，确定HARQ反馈的时间。例如，可以假设中继设备接收到PDCCH中DCI的时隙(slot)是slot#0，那么可以预定义中继设备在slot#0之后的第4个时隙对DCI进行HARQ反馈。显然，此种情况中，DCI中则可以无需包含时间间隔指示，例如类似K1的时间间隔指示。In some embodiments, the time of HARQ feedback can be determined in a predefined manner. For example, it can be assumed that the time slot (slot) in which the relay device receives the DCI in the PDCCH is slot#0, then the relay device can be predefined to perform HARQ feedback on the DCI in the 4th time slot after slot#0. Obviously, in this case, the DCI does not need to include a time interval indication, such as a time interval indication similar to K1.

在一些实施例中，可以通过预配置的方式对HARQ反馈的时频域资源进行配置。可以理解，时频域资源包括时域资源和频域资源，时域资源例如可以是符号(symbol)，频域资源可以是子载波。例如，可以通过RRC信令预先配置一组物理上行控制信道(physical uplink control channel，PUCCH)资源。可以理解，该组PUCCH资源中包括至少一个PUCCH资源。当中继设备需要针对PDCCH中传输的DCI进行HARQ反馈时，可以从该组PUCCH资源中选择一个PUCCH资源进行HARQ反馈。显然，此种情况中，DCI中无需包含PUCCH资源(resource)indicator。In some embodiments, the time-frequency domain resources for HARQ feedback can be configured in a preconfigured manner. It is understood that the time-frequency domain resources include time domain resources and frequency domain resources. The time domain resources can be, for example, symbols, and the frequency domain resources can be subcarriers. For example, a group of physical uplink control channel (PUCCH) resources can be preconfigured through RRC signaling. It is understood that the group of PUCCH resources includes at least one PUCCH resource. When the relay device needs to perform HARQ feedback for the DCI transmitted in the PDCCH, a PUCCH resource can be selected from the group of PUCCH resources for HARQ feedback. Obviously, in this case, the DCI does not need to include a PUCCH resource indicator.

例如，当预先配置的一组PUCCH资源中包括一个PUCCH资源，则中继设备可以选择该PUCCH资源进行HARQ反馈。又例如，当预先配置的一组PUCCH资源中包括多个PUCCH资源，则中继设备可以选择该组PUCCH资源中的任意一个PUCCH资源进行 HARQ反馈。可以根据预先设定的规则或是根据协议中规定的，从该组PUCCH资源中的任意一个PUCCH资源，本公开不作限定。For example, when a pre-configured set of PUCCH resources includes a PUCCH resource, the relay device may select the PUCCH resource for HARQ feedback. For another example, when a pre-configured set of PUCCH resources includes multiple PUCCH resources, the relay device may select any one of the PUCCH resources in the set for HARQ feedback. Any one of the PUCCH resources in the set may be selected according to a pre-set rule or as specified in a protocol, and the present disclosure does not limit this.

在一些实施例中，可以通过预定义的方式，确定HARQ反馈的发送功率。例如预应以PUCCH power control。In some embodiments, the transmit power of the HARQ feedback may be determined in a predefined manner, such as by using PUCCH power control.

当然，可以通过预定义和/或预配置的方式，对HARQ反馈的时间、HARQ反馈的时频域资源和HARQ反馈的发送功率中的任意一项信息进行确定；或是对HARQ反馈的时间和HARQ反馈的时频域资源进行确定；或是对HARQ反馈的时间和HARQ反馈的发送功率进行确定；或是对HARQ反馈的时频域资源和HARQ反馈的发送功率进行确定；或是对HARQ反馈的时间、HARQ反馈的时频域资源和HARQ反馈的发送功率进行确定。Of course, any one of the information including the time of HARQ feedback, the time-frequency domain resources of HARQ feedback and the transmit power of HARQ feedback can be determined in a predefined and/or preconfigured manner; or the time of HARQ feedback and the time-frequency domain resources of HARQ feedback can be determined; or the time of HARQ feedback and the transmit power of HARQ feedback can be determined; or the time-frequency domain resources of HARQ feedback and the transmit power of HARQ feedback can be determined; or the time of HARQ feedback, the time-frequency domain resources of HARQ feedback and the transmit power of HARQ feedback can be determined.

本公开通过预先配置多种参HARQ指示的相关参数，以降低HARQ指示相关的开销，进而节省了资源，提升HARQ反馈的效率。The present disclosure pre-configures a variety of HARQ indication-related parameters to reduce HARQ indication-related overhead, thereby saving resources and improving HARQ feedback efficiency.

本公开实施例提供的混合自动重传反馈方法中，方法还包括：向网络设备发送第一信息，其中，第一信息为HARQ反馈。In the hybrid automatic repeat request feedback method provided by the embodiment of the present disclosure, the method further includes: sending first information to the network device, wherein the first information is HARQ feedback.

在一些实施例中，中继设备可以向网络设备发送第一信息。其中，第一信息用于描述对包括侧控制信息的DCI进行的HARQ反馈。可以理解为，第一信息为上述HARQ反馈In some embodiments, the relay device may send first information to the network device. The first information is used to describe the HARQ feedback for the DCI including the side control information. It can be understood that the first information is the above HARQ feedback

例如，中继设备可以向网络设备发送第一信息。该第一信息可以是HARQ bit。该HARQ bit可以只描述对包括侧控制信息的DCI进行的HARQ反馈，也就是说，该HARQ bit与其它HARQ反馈不进行复用。其中，该HARQ bit可以表示HARQ-ACK或HARQ-NACK。For example, the relay device may send first information to the network device. The first information may be a HARQ bit. The HARQ bit may only describe the HARQ feedback for the DCI including the side control information, that is, the HARQ bit is not multiplexed with other HARQ feedbacks. The HARQ bit may represent HARQ-ACK or HARQ-NACK.

可以理解，中继设备不希望在对包括侧控制信息的DCI进行HARQ反馈(或传输包括侧控制信息的DCI的PDCCH进行HARQ反馈)的slot内，有其它需要反馈的HARQ反馈bit。因此，当在对包括侧控制信息的DCI进行HARQ反馈(或传输包括侧控制信息的DCI的PDCCH进行HARQ反馈)的slot内，有其它需要反馈的HARQ反馈bit的情况下，中继设备可以丢弃其它需要反馈的HARQ反馈bit。使得HARQ反馈信息只包括描述对包括侧控制信息的DCI的HARQ反馈。It can be understood that the relay device does not want other HARQ feedback bits that need to be fed back in the slot for performing HARQ feedback on the DCI including the side control information (or performing HARQ feedback on the PDCCH that transmits the DCI including the side control information). Therefore, when there are other HARQ feedback bits that need to be fed back in the slot for performing HARQ feedback on the DCI including the side control information (or performing HARQ feedback on the PDCCH that transmits the DCI including the side control information), the relay device can discard the other HARQ feedback bits that need to be fed back. This allows the HARQ feedback information to only include the description of the HARQ feedback on the DCI including the side control information.

本公开通过向网络设备发送只描述对包括侧控制信息的DCI进行HARQ反馈的HARQ反馈信息，使得不同信令可以支持不同的反馈方式。进而保证相应信令的正确接收，提升通信系统的鲁棒性。The present disclosure sends HARQ feedback information that only describes HARQ feedback of DCI including side control information to a network device, so that different signaling can support different feedback modes, thereby ensuring correct reception of corresponding signaling and improving the robustness of the communication system.

本公开实施例提供的混合自动重传反馈方法中，方法还包括：向网络设备发送第二信息，其中，第二信息用于联合指示HARQ反馈，和/或，用于指示不同于HARQ反馈的其它HARQ反馈。In the hybrid automatic repeat request feedback method provided by the embodiment of the present disclosure, the method also includes: sending second information to the network device, wherein the second information is used to jointly indicate HARQ feedback and/or to indicate other HARQ feedback different from HARQ feedback.

在一些实施例中，中继设备可以向网络设备发送第二信息。其中，第二信息用于联合 指示HARQ反馈。和/或，第二信息还用于指示不同于HARQ反馈的任意其它HARQ反馈。也就是说，第二信息可以是HARQ反馈与任意其它HARQ反馈进行复用的信息。In some embodiments, the relay device may send second information to the network device. The second information is used to jointly indicate the HARQ feedback. And/or, the second information is also used to indicate any other HARQ feedback different from the HARQ feedback. That is, the second information may be information multiplexed with the HARQ feedback and any other HARQ feedback.

例如，中继设备可以向网络设备发送第二信息。第二信息可以是HARQ bit。该HARQ bit可以即用于描述对包括侧控制信息的DCI的HARQ反馈，也可以用于描述不同于对包括侧控制信息的DCI的HARQ反馈的其它HARQ反馈。其中，该HARQ bit可以表示HARQ-ACK反馈或HARQ-NACK。For example, the relay device may send the second information to the network device. The second information may be a HARQ bit. The HARQ bit may be used to describe the HARQ feedback to the DCI including the side control information, or may be used to describe other HARQ feedback different from the HARQ feedback to the DCI including the side control information. The HARQ bit may represent a HARQ-ACK feedback or a HARQ-NACK.

本公开通过向网络设备发送与其它HARQ反馈进行复用的HARQ反馈信息，使得不同信令可以支持不同的反馈方式。进而保证相应信令的正确接收，提升通信系统的鲁棒性。The present disclosure sends HARQ feedback information multiplexed with other HARQ feedback to a network device, so that different signaling can support different feedback modes, thereby ensuring the correct reception of corresponding signaling and improving the robustness of the communication system.

本公开实施例提供的混合自动重传反馈方法中，HARQ反馈的优先级高于其它HARQ反馈的优先级。In the hybrid automatic repeat request feedback method provided by the embodiment of the present disclosure, the priority of HARQ feedback is higher than the priority of other HARQ feedback.

在一些实施例中，当上述HARQ反馈可以与其它HARQ反馈进行复用的情况下，HARQ反馈的优先级高于其它HARQ反馈的优先级。即，包括侧控制信息的DCI的HARQ反馈的优先级可以设置高于其它HARQ反馈的优先级。In some embodiments, when the above HARQ feedback can be multiplexed with other HARQ feedback, the priority of the HARQ feedback is higher than the priority of other HARQ feedback. That is, the priority of the HARQ feedback of the DCI including the side control information can be set higher than the priority of other HARQ feedback.

例如，当PUCCH资源只够承载2bit信息，而HARQ bit的数量为3，则需要丢弃1bit信息。此时，可以通过优先级方式优先保留优先级较高的bit信息。当设置包括侧控制信息的DCI的HARQ反馈优先级高于其它HARQ反馈的优先级的情况下，将会优先丢弃其它HARQ反馈对应的bit，而保留包括侧控制信息的DCI的HARQ反馈对应的bit。For example, when the PUCCH resource is only enough to carry 2 bits of information, and the number of HARQ bits is 3, 1 bit of information needs to be discarded. In this case, the bit information with higher priority can be retained in a priority manner. When the HARQ feedback priority of the DCI including the side control information is set higher than the priority of other HARQ feedbacks, the bits corresponding to other HARQ feedbacks will be discarded first, and the bits corresponding to the HARQ feedback of the DCI including the side control information will be retained.

本公开通过设置HARQ反馈优先级，以便当PUCCH资源不够的情况下，可以优先保留包括侧控制信息的DCI的HARQ反馈，使得不同信令可以支持不同的反馈方式。进而保证相应信令的正确接收，提升通信系统的鲁棒性。The present disclosure sets the HARQ feedback priority so that when PUCCH resources are insufficient, the HARQ feedback of the DCI including the side control information can be reserved first, so that different signaling can support different feedback modes, thereby ensuring the correct reception of the corresponding signaling and improving the robustness of the communication system.

本公开实施例提供的混合自动重传反馈方法中，图5是根据一示例性实施例示出的又一种混合自动重传反馈方法流程图。如图5所示，方法还可以包括以下步骤：In the hybrid automatic repeat request feedback method provided in the embodiment of the present disclosure, FIG5 is a flow chart of another hybrid automatic repeat request feedback method according to an exemplary embodiment. As shown in FIG5, the method may further include the following steps:

在步骤S31中，接收网络设备发送的资源指示信息。In step S31, resource indication information sent by a network device is received.

在一些实施例中，中继设备可以接收网络设备发送的资源指示信息。其中，资源指示信息用于指示中继设备发送第二信息的PUCCH资源。In some embodiments, the relay device may receive resource indication information sent by the network device, wherein the resource indication information is used to indicate a PUCCH resource for the relay device to send the second information.

例如，中继设备可以接收网络设备发送的一个或多个资源指示信息。For example, the relay device may receive one or more resource indication information sent by the network device.

在步骤S32中，根据资源指示信息确定PUCCH资源。In step S32, the PUCCH resource is determined according to the resource indication information.

在一些实施例中，中继设备可以根据S31中接收到的一个或多个资源指示信息，确定出发送第二信息的PUCCH资源。In some embodiments, the relay device may determine the PUCCH resource for sending the second information according to one or more resource indication information received in S31.

例如，该PUCCH资源可以为在进行HARQ反馈的时隙之前，最后一次接收到网络设备发送的资源指示信息所指示的PUCCH资源。当然，该PUCCH资源也可以为在进行 HARQ反馈的时隙之前，任意第N次接收到网络设备发送的资源指示信息所指示的PUCCH资源，本公开不作限定。For example, the PUCCH resource may be the PUCCH resource indicated by the resource indication information sent by the network device received for the last time before the time slot for HARQ feedback. Of course, the PUCCH resource may also be the PUCCH resource indicated by the resource indication information sent by the network device received for any Nth time before the time slot for HARQ feedback, which is not limited in the present disclosure.

例如，当包括侧控制信息的DCI的HARQ反馈可以与其它HARQ反馈进行复用的情况下，中继设备在slot#1接收到资源指示信息1，指示在slot#9的PUCCH资源#1上反馈HARQ 1。中继设备还可以在slot#3接收到资源指示信息2，指示在slot#9的PUCCH资源#2上反馈HARQ 2。中继设备可以确定在slot#9的PUCCH资源#2上进行HARQ反馈。For example, when the HARQ feedback of the DCI including the side control information can be multiplexed with other HARQ feedbacks, the relay device receives resource indication information 1 in slot#1, indicating that HARQ 1 is fed back on PUCCH resource #1 in slot#9. The relay device can also receive resource indication information 2 in slot#3, indicating that HARQ 2 is fed back on PUCCH resource #2 in slot#9. The relay device can determine to perform HARQ feedback on PUCCH resource #2 in slot#9.

在步骤S33中，基于PUCCH资源向网络设备发送第二信息。In step S33, second information is sent to the network device based on the PUCCH resources.

在一些实施例中，中继设备可以在S32中确定的PUCCH资源上，向网络设备发送第二信息。In some embodiments, the relay device may send the second information to the network device on the PUCCH resource determined in S32.

例如，中继设备可以在slot#9的PUCCH资源#2上一起反馈HARQ 1和HARQ 2。其中，HARQ 1、HARQ 2中有一个是包括侧控制信息的DCI的HARQ反馈；另一个是其它HARQ反馈。For example, the relay device can feed back HARQ 1 and HARQ 2 together on PUCCH resource #2 in slot #9. Among them, one of HARQ 1 and HARQ 2 is the HARQ feedback of DCI including side control information; the other is other HARQ feedback.

可以理解，发送第二信息的PUCCH资源可以根据距离该次反馈时隙最近的一次调度所指示的PUCCH资源确定。It can be understood that the PUCCH resource for sending the second information can be determined according to the PUCCH resource indicated by the latest scheduling to the feedback time slot.

本公开提供了发送HARQ反馈信息的PUCCH资源确定方式，以便在包括侧控制信息的DCI的HARQ反馈可以与其它HARQ反馈进行复用的情况下，可以选择相应的PUCCH发送相应HARQ反馈信息，使得不同信令可以支持不同的反馈方式。进而保证相应信令的正确接收，提升通信系统的鲁棒性。The present disclosure provides a PUCCH resource determination method for sending HARQ feedback information, so that when the HARQ feedback of the DCI including the side control information can be multiplexed with other HARQ feedbacks, the corresponding PUCCH can be selected to send the corresponding HARQ feedback information, so that different signaling can support different feedback methods, thereby ensuring the correct reception of the corresponding signaling and improving the robustness of the communication system.

基于相同构思，本公开还提供了一种应用于网络设备的混合自动重传反馈方法。Based on the same concept, the present disclosure also provides a hybrid automatic retransmission feedback method applied to a network device.

图6是根据一示例性实施例示出的再一种混合自动重传反馈方法流程图，如图6所示，方法由网络设备执行。方法可以包括以下步骤：FIG6 is a flow chart of another hybrid automatic repeat request feedback method according to an exemplary embodiment. As shown in FIG6 , the method is executed by a network device. The method may include the following steps:

在步骤S41中，向中继设备发送下行控制信息DCI。In step S41, downlink control information DCI is sent to the relay device.

在一些实施例中，网络设备可以向中继设备发送DCI。其中，该DCI包括侧控制信息，该DCI在PDCCH上进行传输，该DCI用于指示中继设备确定是否向网络设备进行HARQ反馈。HARQ反馈表示对包括侧控制信息的DCI进行HARQ反馈。In some embodiments, the network device may send DCI to the relay device. The DCI includes side control information, the DCI is transmitted on the PDCCH, and the DCI is used to instruct the relay device to determine whether to perform HARQ feedback to the network device. The HARQ feedback indicates performing HARQ feedback on the DCI including the side control information.

例如，网络设备向中继设备发送包括侧控制信息的DCI。该DCI用于中继设备确定是否对包括侧控制信息的DCI进行HARQ反馈。For example, the network device sends a DCI including the side control information to the relay device. The DCI is used by the relay device to determine whether to perform HARQ feedback on the DCI including the side control information.

例如，是否向网络设备进行HARQ反馈，可以包括进行HARQ反馈以及不进行HARQ反馈。For example, whether to perform HARQ feedback to the network device may include performing HARQ feedback or not performing HARQ feedback.

可以理解，由于DCI在PDCCH上传输，因此对DCI进行HARQ反馈，也可以认为是对传输该DCI的PDCCH进行HARQ反馈。It can be understood that, since the DCI is transmitted on the PDCCH, performing HARQ feedback on the DCI can also be considered as performing HARQ feedback on the PDCCH that transmits the DCI.

本公开通过DCI对包括侧控制信息的DCI进行HARQ反馈的指示，使得不同信令可以支持不同的反馈方式。进而保证相应信令的正确接收，提升通信系统的鲁棒性。The present disclosure uses DCI to indicate HARQ feedback on DCI including side control information, so that different signaling can support different feedback modes, thereby ensuring the correct reception of corresponding signaling and improving the robustness of the communication system.

本公开实施例提供的混合自动重传反馈方法中，DCI还包括HARQ反馈指示域，HARQ反馈指示域用于指示是否向网络设备进行HARQ反馈。In the hybrid automatic repeat request feedback method provided by the embodiment of the present disclosure, the DCI also includes a HARQ feedback indication field, and the HARQ feedback indication field is used to indicate whether to perform HARQ feedback to the network device.

在一些实施例中，网络设备发送的包括侧控制信息的DCI中，还可以包括HARQ反馈指示域。该HARQ反馈指示域用于指示中继设备是否向网络设备进行HARQ反馈。例如，中继设备是否向网络设备对包括侧控制信息的DCI进行HARQ反馈。In some embodiments, the DCI including the side control information sent by the network device may also include a HARQ feedback indication field. The HARQ feedback indication field is used to indicate whether the relay device performs HARQ feedback to the network device. For example, whether the relay device performs HARQ feedback to the network device for the DCI including the side control information.

例如，HARQ反馈指示域可以指示中继设备向网络设备对包括侧控制信息的DCI进行HARQ反馈。或者，HARQ反馈指示域可以指示中继设备不向网络设备对包括侧控制信息的DCI进行HARQ反馈。For example, the HARQ feedback indication field may indicate that the relay device performs HARQ feedback on the DCI including the side control information to the network device. Alternatively, the HARQ feedback indication field may indicate that the relay device does not perform HARQ feedback on the DCI including the side control information to the network device.

例如，HARQ反馈可以是HARQ-ACK或HARQ-NACK。For example, the HARQ feedback may be HARQ-ACK or HARQ-NACK.

本公开通过DCI中的HARQ反馈指示域，指示中继设备是否对包括侧控制信息的DCI进行HARQ反馈，使得不同信令可以支持不同的反馈方式。进而保证相应信令的正确接收，提升通信系统的鲁棒性。The present disclosure uses the HARQ feedback indication field in the DCI to indicate whether the relay device performs HARQ feedback on the DCI including the side control information, so that different signaling can support different feedback modes, thereby ensuring the correct reception of the corresponding signaling and improving the robustness of the communication system.

本公开实施例提供的混合自动重传反馈方法中，HARQ反馈指示域为第一数值，第一数值表示对DCI进行HARQ反馈。In the hybrid automatic repeat request feedback method provided by the embodiment of the present disclosure, the HARQ feedback indication field is a first value, and the first value indicates HARQ feedback for DCI.

在一些实施例中，HARQ反馈指示域可以为第一数值，在此情况中，HARQ反馈指示域的第一数值可以表示对包括侧控制信息的DCI进行HARQ反馈。In some embodiments, the HARQ feedback indication field may be a first value. In this case, the first value of the HARQ feedback indication field may indicate that HARQ feedback is performed on the DCI including the side control information.

例如，HARQ反馈指示域为第一数值，第一数值表示对包括侧控制信息的DCI进行HARQ-ACK反馈。For example, the HARQ feedback indication field is a first value, and the first value indicates that HARQ-ACK feedback is performed on the DCI including the side control information.

又例如，HARQ反馈指示域为第一数值，第一数值表示对包括侧控制信息的DCI进行HARQ-NACK反馈。For another example, the HARQ feedback indication field is a first value, and the first value indicates that HARQ-NACK feedback is performed on the DCI including the side control information.

可以理解，若包括侧控制信息的DCI对时延要求不高的情况下，可以对包括侧控制信息的DCI进行HARQ反馈。It can be understood that if the DCI including the side control information does not have a high requirement on the delay, HARQ feedback can be performed on the DCI including the side control information.

本公开通过HARQ反馈指示域为第一数值以指示包括侧控制信息的DCI进行HARQ反馈，使得不同信令可以支持不同的反馈方式。进而保证相应信令的正确接收，提升通信系统的鲁棒性。The present disclosure uses the HARQ feedback indication field as the first value to indicate that the DCI including the side control information performs HARQ feedback, so that different signaling can support different feedback modes, thereby ensuring the correct reception of the corresponding signaling and improving the robustness of the communication system.

本公开实施例提供的混合自动重传反馈方法中，HARQ反馈指示域为第二数值，第二数值表示对包括侧控制信息的DCI不进行HARQ反馈。In the hybrid automatic repeat request feedback method provided by the embodiment of the present disclosure, the HARQ feedback indication field is a second value, and the second value indicates that HARQ feedback is not performed on the DCI including the side control information.

在一些实施例中，HARQ反馈指示域可以为第二数值，在此情况中，HARQ反馈指示域的第二数值可以表示对包括侧控制信息的DCI不进行HARQ反馈。In some embodiments, the HARQ feedback indication field may be a second value. In this case, the second value of the HARQ feedback indication field may indicate that no HARQ feedback is performed on the DCI including the side control information.

例如，HARQ反馈指示域为第二数值，第二数值表示对包括侧控制信息的DCI不进行HARQ-ACK反馈。For example, the HARQ feedback indication field is a second value, and the second value indicates that HARQ-ACK feedback is not performed for the DCI including the side control information.

又例如，HARQ反馈指示域为第二数值，第二数值表示对包括侧控制信息的DCI不进行HARQ-NACK反馈。For another example, the HARQ feedback indication field is a second value, and the second value indicates that HARQ-NACK feedback is not performed for the DCI including the side control information.

可以理解，若包括侧控制信息的DCI对时延要求高的情况下，可以不对包括侧控制信息的DCI进行HARQ反馈。It can be understood that if the DCI including the side control information has a high delay requirement, HARQ feedback may not be performed on the DCI including the side control information.

本公开通过HARQ反馈指示域为第二数值以指示包括侧控制信息的DCI不进行HARQ反馈，使得不同信令可以支持不同的反馈方式。进而保证相应信令的正确接收，提升通信系统的鲁棒性。The present disclosure uses the HARQ feedback indication field as the second value to indicate that the DCI including the side control information does not perform HARQ feedback, so that different signaling can support different feedback modes, thereby ensuring the correct reception of the corresponding signaling and improving the robustness of the communication system.

本公开实施例提供的混合自动重传反馈方法中，HARQ反馈包括以下任意一项：混合自动重传确认HARQ-ACK；混合自动重传否定确认HARQ-NACK。In the hybrid automatic repeat request feedback method provided in the embodiment of the present disclosure, the HARQ feedback includes any one of the following: a hybrid automatic repeat request confirmation HARQ-ACK; a hybrid automatic repeat request negative confirmation HARQ-NACK.

在一些实施例中，HARQ反馈可以是混合自动重传确认HARQ-ACK。In some embodiments, the HARQ feedback may be a Hybrid Automatic Repeat Request Acknowledgement HARQ-ACK.

例如，当中继设备正确解调侧控制信息时，可以向网络设备发送HARQ-ACK。For example, when the relay device correctly demodulates the side control information, it can send a HARQ-ACK to the network device.

在一些实施例中，HARQ反馈可以是混合自动重传否定确认HARQ-NACK。In some embodiments, the HARQ feedback may be a hybrid automatic repeat request negative acknowledgement HARQ-NACK.

例如，当中继设备没有正确解调侧控制信息时，可以向网络设备发送HARQ-NACK。For example, when the relay device fails to correctly demodulate the side control information, it may send a HARQ-NACK to the network device.

本公开可以支持多种HARQ的反馈信息，以适应多种通信场景。进而保证相应信令的正确接收，提升通信系统的鲁棒性。The present disclosure can support multiple HARQ feedback information to adapt to multiple communication scenarios, thereby ensuring the correct reception of corresponding signaling and improving the robustness of the communication system.

本公开实施例提供的混合自动重传反馈方法中，HARQ反馈指示域为专用信息位，专用信息位只用于指示是否进行HARQ反馈。In the hybrid automatic repeat request feedback method provided by the embodiment of the present disclosure, the HARQ feedback indication field is a dedicated information bit, and the dedicated information bit is only used to indicate whether to perform HARQ feedback.

在一些实施例中，HARQ反馈指示域可以是专用信息位，该专用信息位可以只用于指示是否对包括侧控制信息的DCI进行HARQ反馈。In some embodiments, the HARQ feedback indication field may be a dedicated information bit, which may be used only to indicate whether to perform HARQ feedback on the DCI including the side control information.

例如，可以在DCI中新增专用信息位，如HARQ feedback enable/disable信息位。For example, dedicated information bits may be added to the DCI, such as the HARQ feedback enable/disable information bits.

如，当HARQ feedback enable/disable信息位为第一数值时，可以表示为enable，即指示中继设备需要对包括侧控制信息的DCI进行HARQ反馈。也可以理解为，指示中继设备需要对传输包括侧控制信息的DCI的PDCCH进行HARQ反馈。如，可以是发送HARQ-ACK或发送HARQ-NACK。For example, when the HARQ feedback enable/disable information bit is the first value, it can be represented as enable, indicating that the relay device needs to perform HARQ feedback on the DCI including the side control information. It can also be understood as indicating that the relay device needs to perform HARQ feedback on the PDCCH that transmits the DCI including the side control information. For example, it can be sending HARQ-ACK or sending HARQ-NACK.

又如，当HARQ feedback enable/disable信息位为第二数值时，可以表示为disable，即指示中继设备不需要对包括侧控制信息的DCI进行HARQ反馈。也可以理解为，指示中继设备不需要对传输包括侧控制信息的DCI的PDCCH进行HARQ反馈。如，可以不发送HARQ-ACK以及HARQ-NACK。For another example, when the HARQ feedback enable/disable information bit is the second value, it can be represented as disable, which indicates that the relay device does not need to perform HARQ feedback on the DCI including the side control information. It can also be understood as indicating that the relay device does not need to perform HARQ feedback on the PDCCH that transmits the DCI including the side control information. For example, HARQ-ACK and HARQ-NACK may not be sent.

例如，HARQ feedback enable/disable信息位可以是1bit的信息位，第一数值可以是1， 第二数值可以是0。或者，第一数值可以是0，第二数值可以是1。本公开对第一数值、第二数据的具体数值不作限定。For example, the HARQ feedback enable/disable information bit may be a 1-bit information bit, the first value may be 1, and the second value may be 0. Alternatively, the first value may be 0, and the second value may be 1. The present disclosure does not limit the specific values of the first value and the second value.

本公开通过在DCI中新增专用于指示是否对包括侧控制信息的DCI进行HARQ反馈的专用信息位，使得不同信令可以支持不同的反馈方式。进而保证相应信令的正确接收，提升通信系统的鲁棒性。The present disclosure adds a dedicated information bit in DCI for indicating whether to perform HARQ feedback on the DCI including the side control information, so that different signaling can support different feedback modes, thereby ensuring the correct reception of the corresponding signaling and improving the robustness of the communication system.

本公开实施例提供的混合自动重传反馈方法中，HARQ反馈指示域为复用信息域，复用信息域用于联合指示是否进行HARQ反馈，以及用于指示反馈不同于HARQ反馈的其它信息。In the hybrid automatic repeat request feedback method provided by the embodiment of the present disclosure, the HARQ feedback indication field is a multiplexed information field, and the multiplexed information field is used to jointly indicate whether to perform HARQ feedback, and to indicate feedback of other information different from HARQ feedback.

在一些实施例中，HARQ反馈指示域可以是复用信息域，即DCI中已有的信息域。且该信息域已用于指示不同于上述HARQ反馈的其它信息。也就是说，HARQ反馈指示域可以复用DCI中已有的信息域，作为复用信息域。使得复用信息域可以用于联合指示是否对包括侧控制信息的DCI进行HARQ反馈，以及用于指示反馈不同于上述HARQ反馈的任意其它信息。In some embodiments, the HARQ feedback indication field may be a multiplexed information field, that is, an existing information field in the DCI. And the information field has been used to indicate other information different from the above HARQ feedback. In other words, the HARQ feedback indication field may reuse the existing information field in the DCI as the multiplexed information field. The multiplexed information field may be used to jointly indicate whether to perform HARQ feedback on the DCI including the side control information, and to indicate feedback of any other information different from the above HARQ feedback.

例如，HARQ反馈指示域可以复用HARQ process ID作为复用信息域进行指示。For example, the HARQ feedback indication field can reuse the HARQ process ID as the multiplexing information field for indication.

如，当HARQ process ID为第一数值时，可以指示中继设备需要对包括侧控制信息的DCI进行HARQ反馈。也可以理解为，指示中继设备需要对传输包括侧控制信息的DCI的PDCCH进行HARQ反馈。如，可以发送HARQ-ACK或HARQ-NACK。For example, when the HARQ process ID is the first value, it can indicate that the relay device needs to perform HARQ feedback on the DCI including the side control information. It can also be understood as indicating that the relay device needs to perform HARQ feedback on the PDCCH that transmits the DCI including the side control information. For example, HARQ-ACK or HARQ-NACK can be sent.

又如，当HARQ process ID为第二数值时，可以指示中继设备不需要对包括侧控制信息的DCI进行HARQ反馈。也可以理解为，指示中继设备不需要对传输包括侧控制信息的DCI的PDCCH进行HARQ反馈。如，可以不发送HARQ-ACK以及HARQ-NACK。For another example, when the HARQ process ID is the second value, it can indicate that the relay device does not need to perform HARQ feedback on the DCI including the side control information. It can also be understood as indicating that the relay device does not need to perform HARQ feedback on the PDCCH that transmits the DCI including the side control information. For example, HARQ-ACK and HARQ-NACK may not be sent.

例如，HARQ process ID为第一数值可以是0，第二数值可以是非0。或者，第一数值可以是任意数值，第二数值可以是与第一数值不同的数值。本公开对第一数值、第二数据的具体数值不作限定。For example, the first value of the HARQ process ID may be 0, and the second value may be non-0. Alternatively, the first value may be any value, and the second value may be a value different from the first value. The present disclosure does not limit the specific values of the first value and the second value.

在一些实施例中，HARQ反馈指示域可以是对DCI中任意已有的信息域进行重新翻译，并作为复用信息域。以便用于联合指示是否进行HARQ反馈，以及不同于HARQ反馈的其它信息。In some embodiments, the HARQ feedback indication field may be a retranslation of any existing information field in the DCI and used as a multiplexed information field to jointly indicate whether to perform HARQ feedback and other information different from HARQ feedback.

其中，复用信息域可以在同一时刻同时指示是否进行HARQ反馈以及不同于HARQ反馈的其它信息。比如MCS域的最高比特位用于指示是否进行HARQ反馈，剩余的比特位用于指示调制编码方式。The multiplexed information field can indicate whether to perform HARQ feedback and other information different from HARQ feedback at the same time. For example, the highest bit of the MCS field is used to indicate whether to perform HARQ feedback, and the remaining bits are used to indicate the modulation and coding mode.

又例如，复用信息域还可以在不同情况下指示是否进行HARQ反馈或者不同于HARQ反馈的其它信息。比如在特定情况下，如特定的RNTI加扰方式1下，表示是否进行HARQ 反馈，在特定的RNTI加扰方式2下，表示不同于HARQ反馈的其它信息。For another example, the multiplexing information field may also indicate whether to perform HARQ feedback or other information different from HARQ feedback in different situations. For example, in a specific situation, such as a specific RNTI scrambling mode 1, it indicates whether to perform HARQ feedback, and in a specific RNTI scrambling mode 2, it indicates other information different from HARQ feedback.

本公开通过复用DCI中已有的信息域，以指示是否对包括侧控制信息的DCI进行HARQ反馈，使得不同信令可以支持不同的反馈方式。进而保证相应信令的正确接收，提升通信系统的鲁棒性。The present disclosure multiplexes the existing information field in DCI to indicate whether to perform HARQ feedback on the DCI including the side control information, so that different signaling can support different feedback modes, thereby ensuring the correct reception of the corresponding signaling and improving the robustness of the communication system.

本公开实施例提供的混合自动重传反馈方法中，图7是根据一示例性实施例示出的另一种混合自动重传反馈方法流程图。如图7所示，DCI还包括HARQ反馈指示域，方法还可以包括以下步骤：In the hybrid automatic repeat request feedback method provided in the embodiment of the present disclosure, FIG7 is a flow chart of another hybrid automatic repeat request feedback method according to an exemplary embodiment. As shown in FIG7, the DCI also includes a HARQ feedback indication field, and the method may further include the following steps:

在步骤S51中，向中继设备发送无线资源控制RRC信令。In step S51, a radio resource control RRC signaling is sent to the relay device.

在一些实施例中，网络设备可以向中继设备发送RRC信令。该RRC信令可以用于指示HARQ反馈指示域内数值与是否进行HARQ反馈的对应关系。In some embodiments, the network device may send an RRC signaling to the relay device. The RRC signaling may be used to indicate the corresponding relationship between the value in the HARQ feedback indication field and whether to perform HARQ feedback.

例如，当HARQ反馈指示域为专用信息位时，RRC信令可以用于指示该专用信息位中第一数值和/或第二数值，与是否进行HARQ反馈的对应关系。如指示以下至少一种对应关系：第一数值表示发送HARQ-ACK或HARQ-NACK；第一数值表示不发送HARQ-ACK和HARQ-NACK；第二数值表示发送HARQ-ACK或HARQ-NACK；第二数值表示不发送HARQ-ACK和HARQ-NACK。For example, when the HARQ feedback indication field is a dedicated information bit, the RRC signaling can be used to indicate the correspondence between the first value and/or the second value in the dedicated information bit and whether HARQ feedback is performed. For example, at least one of the following correspondences is indicated: the first value indicates sending HARQ-ACK or HARQ-NACK; the first value indicates not sending HARQ-ACK and HARQ-NACK; the second value indicates sending HARQ-ACK or HARQ-NACK; the second value indicates not sending HARQ-ACK and HARQ-NACK.

又例如，当HARQ反馈指示域为复用信息域时，RRC信令可以用于指示该复用信息域中第一数值和/或第二数值，与是否进行HARQ反馈的对应关系。如指示以下至少一种对应关系：第一数值表示发送HARQ-ACK或HARQ-NACK；第一数值表示不发送HARQ-ACK和HARQ-NACK；第二数值表示发送HARQ-ACK或HARQ-NACK；第二数值表示不发送HARQ-ACK和HARQ-NACK。For another example, when the HARQ feedback indication field is a multiplexing information field, the RRC signaling may be used to indicate the correspondence between the first value and/or the second value in the multiplexing information field and whether HARQ feedback is performed. For example, at least one of the following correspondences is indicated: the first value indicates sending HARQ-ACK or HARQ-NACK; the first value indicates not sending HARQ-ACK and HARQ-NACK; the second value indicates sending HARQ-ACK or HARQ-NACK; the second value indicates not sending HARQ-ACK and HARQ-NACK.

本公开可以通过RRC指示HARQ反馈指示域内数值与是否进行HARQ反馈的对应关系，以便通过HARQ反馈指示域内数值指示是否对包括侧控制信息的DCI进行HARQ反馈，使得不同信令可以支持不同的反馈方式。进而保证相应信令的正确接收，提升通信系统的鲁棒性。The present disclosure can indicate the correspondence between the value in the HARQ feedback indication field and whether to perform HARQ feedback through RRC, so as to indicate whether to perform HARQ feedback on the DCI including the side control information through the value in the HARQ feedback indication field, so that different signaling can support different feedback modes, thereby ensuring the correct reception of the corresponding signaling and improving the robustness of the communication system.

本公开实施例提供的混合自动重传反馈方法中，基于预定义规则确定以下至少一种信息：HARQ反馈的时间；HARQ反馈的时频域资源；HARQ反馈的发送功率。In the hybrid automatic repeat request feedback method provided by the embodiment of the present disclosure, at least one of the following information is determined based on predefined rules: the time of HARQ feedback; the time-frequency domain resources of HARQ feedback; and the transmission power of HARQ feedback.

其中，在一些实施例中，为了降低HARQ指示相关的开销，可以通过预定义和/或预配置的方式，对HARQ反馈的时间、HARQ反馈的时频域资源和HARQ反馈的发送功率中的至少一项信息进行确定。In some embodiments, in order to reduce the overhead related to the HARQ indication, at least one of the information including the time of HARQ feedback, the time-frequency domain resources of HARQ feedback and the transmit power of HARQ feedback can be determined in a predefined and/or preconfigured manner.

在一些实施例中，可以通过预定义的方式，确定HARQ反馈的时间。例如，可以假设中继设备接收到PDCCH中DCI的slot是slot#0，那么可以预定义中继设备在slot#0之后 的第4个时隙对DCI进行HARQ反馈。显然，此种情况中，DCI中则可以无需包含时间间隔指示，例如类似K1的时间间隔指示。In some embodiments, the time of HARQ feedback can be determined in a predefined manner. For example, it can be assumed that the slot in which the relay device receives the DCI in the PDCCH is slot#0, and then the relay device can be predefined to perform HARQ feedback on the DCI in the 4th time slot after slot#0. Obviously, in this case, the DCI does not need to include a time interval indication, such as a time interval indication similar to K1.

在一些实施例中，可以通过预配置的方式对HARQ反馈的时频域资源进行配置。可以理解，时频域资源包括时域资源和频域资源，时域资源例如可以是symbol，频域资源可以是子载波。例如，可以通过RRC信令预先配置一组PUCCH资源。可以理解，该组PUCCH资源中包括至少一个PUCCH资源。当中继设备需要针对PDCCH中传输的DCI进行HARQ反馈时，可以从该组PUCCH资源中选择一个PUCCH资源进行HARQ反馈。显然，此种情况中，DCI中无需包含PUCCH resource indicator。In some embodiments, the time-frequency domain resources for HARQ feedback can be configured in a preconfigured manner. It is understood that the time-frequency domain resources include time domain resources and frequency domain resources. The time domain resources can be, for example, symbols, and the frequency domain resources can be subcarriers. For example, a group of PUCCH resources can be preconfigured through RRC signaling. It is understood that the group of PUCCH resources includes at least one PUCCH resource. When the relay device needs to perform HARQ feedback for the DCI transmitted in the PDCCH, a PUCCH resource can be selected from the group of PUCCH resources for HARQ feedback. Obviously, in this case, the DCI does not need to include a PUCCH resource indicator.

例如，当预先配置的一组PUCCH资源中包括一个PUCCH资源，则中继设备可以选择该PUCCH资源进行HARQ反馈。又例如，当预先配置的一组PUCCH资源中包括多个PUCCH资源，则中继设备可以选择该组PUCCH资源中的任意一个PUCCH资源进行HARQ反馈。可以根据预先设定的规则或是根据协议中规定的，从该组PUCCH资源中的任意一个PUCCH资源，本公开不作限定。For example, when a pre-configured set of PUCCH resources includes a PUCCH resource, the relay device may select the PUCCH resource for HARQ feedback. For another example, when a pre-configured set of PUCCH resources includes multiple PUCCH resources, the relay device may select any one of the PUCCH resources in the set for HARQ feedback. Any one of the PUCCH resources in the set may be selected according to a pre-set rule or as specified in a protocol, and the present disclosure does not limit this.

在一些实施例中，可以通过预定义的方式，确定HARQ反馈的发送功率。例如预应以PUCCH power control。In some embodiments, the transmit power of the HARQ feedback may be determined in a predefined manner, such as by using PUCCH power control.

当然，可以通过预定义和/或预配置的方式，对HARQ反馈的时间、HARQ反馈的时频域资源和HARQ反馈的发送功率中的任意一项信息进行确定；或是对HARQ反馈的时间和HARQ反馈的时频域资源进行确定；或是对HARQ反馈的时间和HARQ反馈的发送功率进行确定；或是对HARQ反馈的时频域资源和HARQ反馈的发送功率进行确定；或是对HARQ反馈的时间、HARQ反馈的时频域资源和HARQ反馈的发送功率进行确定。Of course, any one of the information including the time of HARQ feedback, the time-frequency domain resources of HARQ feedback and the transmit power of HARQ feedback can be determined in a predefined and/or preconfigured manner; or the time of HARQ feedback and the time-frequency domain resources of HARQ feedback can be determined; or the time of HARQ feedback and the transmit power of HARQ feedback can be determined; or the time-frequency domain resources of HARQ feedback and the transmit power of HARQ feedback can be determined; or the time of HARQ feedback, the time-frequency domain resources of HARQ feedback and the transmit power of HARQ feedback can be determined.

本公开通过预先配置多种参HARQ指示的相关参数，以降低HARQ指示相关的开销，进而节省了资源，提升HARQ反馈的效率。The present disclosure pre-configures a variety of HARQ indication-related parameters to reduce HARQ indication-related overhead, thereby saving resources and improving HARQ feedback efficiency.

本公开实施例提供的混合自动重传反馈方法中，方法还包括：接收中继设备发送的第一信息，其中，第一信息为HARQ反馈。In the hybrid automatic repeat request feedback method provided by the embodiment of the present disclosure, the method further includes: receiving first information sent by a relay device, wherein the first information is HARQ feedback.

在一些实施例中，网络设备可以接收中继设备发送的第一信息。其中，第一信息用于描述对包括侧控制信息的DCI进行的HARQ反馈。In some embodiments, the network device may receive first information sent by the relay device, wherein the first information is used to describe HARQ feedback performed on the DCI including the side control information.

例如，网络设备可以接收中继设备发送的第一信息。第一信息可以是HARQ bit。该HARQ bit可以只描述对包括侧控制信息的DCI进行的HARQ反馈，也就是说，该HARQ bit与其它HARQ反馈不进行复用。其中，该HARQ bit可以表示HARQ-ACK或HARQ-NACK。For example, the network device may receive first information sent by the relay device. The first information may be a HARQ bit. The HARQ bit may only describe the HARQ feedback for the DCI including the side control information, that is, the HARQ bit is not multiplexed with other HARQ feedbacks. The HARQ bit may represent HARQ-ACK or HARQ-NACK.

可以理解，中继设备不希望在对包括侧控制信息的DCI进行HARQ反馈(或传输包 括侧控制信息的DCI的PDCCH进行HARQ反馈)的slot内，有其它需要反馈的HARQ反馈bit。因此，当在对包括侧控制信息的DCI进行HARQ反馈(或传输包括侧控制信息的DCI的PDCCH进行HARQ反馈)的slot内，有其它需要反馈的HARQ反馈bit的情况下，中继设备可以丢弃其它需要反馈的HARQ反馈bit。使得HARQ反馈信息只包括描述对包括侧控制信息的DCI的HARQ反馈。It can be understood that the relay device does not want other HARQ feedback bits that need to be fed back in the slot for performing HARQ feedback on the DCI including the side control information (or performing HARQ feedback on the PDCCH that transmits the DCI including the side control information). Therefore, when other HARQ feedback bits that need to be fed back are present in the slot for performing HARQ feedback on the DCI including the side control information (or performing HARQ feedback on the PDCCH that transmits the DCI including the side control information), the relay device may discard other HARQ feedback bits that need to be fed back, so that the HARQ feedback information only includes the description of the HARQ feedback on the DCI including the side control information.

本公开通过向网络设备发送只描述对包括侧控制信息的DCI进行HARQ反馈的HARQ反馈信息，使得不同信令可以支持不同的反馈方式。进而保证相应信令的正确接收，提升通信系统的鲁棒性。The present disclosure sends HARQ feedback information that only describes HARQ feedback of DCI including side control information to a network device, so that different signaling can support different feedback modes, thereby ensuring correct reception of corresponding signaling and improving the robustness of the communication system.

本公开实施例提供的混合自动重传反馈方法中，方法还包括：接收中继设备发送的第二信息，其中，第二信息用于联合指示HARQ反馈，和/或，用于指示不同于HARQ反馈的其它HARQ反馈。In the hybrid automatic repeat request feedback method provided by the embodiment of the present disclosure, the method also includes: receiving second information sent by the relay device, wherein the second information is used to jointly indicate HARQ feedback and/or to indicate other HARQ feedback different from HARQ feedback.

在一些实施例中，网络设备可以接收中继设备发送的第二信息。其中，第二信息用于联合指示HARQ反馈。和/或，第二信息还用于指示不同于HARQ反馈的任意其它HARQ反馈。也就是说，第二信息可以是HARQ反馈与任意其它HARQ反馈进行复用的信息。In some embodiments, the network device may receive second information sent by the relay device. The second information is used to jointly indicate the HARQ feedback. And/or, the second information is also used to indicate any other HARQ feedback different from the HARQ feedback. That is, the second information may be information multiplexed with the HARQ feedback and any other HARQ feedback.

例如，网络设备可以接收中继设备发送的第二信息。第二信息可以是HARQ bit。该HARQ bit可以即用于描述对包括侧控制信息的DCI的HARQ反馈，也可以用于描述不同于对包括侧控制信息的DCI的HARQ反馈的其它HARQ反馈。其中，该HARQ bit可以表示HARQ-ACK或HARQ-NACK。For example, the network device may receive the second information sent by the relay device. The second information may be a HARQ bit. The HARQ bit may be used to describe the HARQ feedback for the DCI including the side control information, or may be used to describe other HARQ feedback different from the HARQ feedback for the DCI including the side control information. The HARQ bit may represent HARQ-ACK or HARQ-NACK.

本公开通过向网络设备发送与其它HARQ反馈进行复用的HARQ反馈信息，使得不同信令可以支持不同的反馈方式。进而保证相应信令的正确接收，提升通信系统的鲁棒性。The present disclosure sends HARQ feedback information multiplexed with other HARQ feedback to a network device, so that different signaling can support different feedback modes, thereby ensuring the correct reception of corresponding signaling and improving the robustness of the communication system.

本公开实施例提供的混合自动重传反馈方法中，HARQ反馈的优先级高于其它HARQ反馈的优先级。In the hybrid automatic repeat request feedback method provided by the embodiment of the present disclosure, the priority of HARQ feedback is higher than the priority of other HARQ feedback.

在一些实施例中，当HARQ反馈可以与其它HARQ反馈进行复用的情况下，HARQ反馈的优先级高于其它HARQ反馈的优先级。即，包括侧控制信息的DCI的HARQ反馈的优先级可以设置高于其它HARQ反馈的优先级。In some embodiments, when HARQ feedback can be multiplexed with other HARQ feedback, the priority of HARQ feedback is higher than the priority of other HARQ feedback. That is, the priority of HARQ feedback of DCI including side control information can be set higher than the priority of other HARQ feedback.

例如，当PUCCH资源只够承载2bit信息，而HARQ bit的数量为3，则需要丢弃1bit信息。此时，可以通过优先级方式优先保留优先级较高的bit信息。当设置包括侧控制信息的DCI的HARQ反馈优先级高于其它HARQ反馈的优先级的情况下，将会优先丢弃其它HARQ反馈对应的bit，而保留包括侧控制信息的DCI的HARQ反馈对应的bit。For example, when the PUCCH resource is only enough to carry 2 bits of information, and the number of HARQ bits is 3, 1 bit of information needs to be discarded. In this case, the bit information with higher priority can be retained in a priority manner. When the HARQ feedback priority of the DCI including the side control information is set higher than the priority of other HARQ feedbacks, the bits corresponding to other HARQ feedbacks will be discarded first, and the bits corresponding to the HARQ feedback of the DCI including the side control information will be retained.

本公开通过设置HARQ反馈优先级，以便当PUCCH资源不够的情况下，可以优先保留包括侧控制信息的DCI的HARQ反馈，使得不同信令可以支持不同的反馈方式。进而 保证相应信令的正确接收，提升通信系统的鲁棒性。The present disclosure sets the HARQ feedback priority so that when PUCCH resources are insufficient, the HARQ feedback of the DCI including the side control information can be reserved preferentially, so that different signaling can support different feedback modes, thereby ensuring the correct reception of the corresponding signaling and improving the robustness of the communication system.

本公开实施例提供的混合自动重传反馈方法中，图8是根据一示例性实施例示出的又一种混合自动重传反馈方法流程图。如图8所示，方法还可以包括以下步骤：In the hybrid automatic repeat request feedback method provided in the embodiment of the present disclosure, FIG8 is a flow chart of another hybrid automatic repeat request feedback method according to an exemplary embodiment. As shown in FIG8, the method may further include the following steps:

在步骤S61中，向中继设备发送资源指示信息。In step S61, resource indication information is sent to the relay device.

在一些实施例中，网络设备可以向中继设备发送资源指示信息。其中，资源指示信息用于指示中继设备发送第二信息的PUCCH资源。In some embodiments, the network device may send resource indication information to the relay device, wherein the resource indication information is used to indicate a PUCCH resource for the relay device to send the second information.

在步骤S62中，基于PUCCH资源接收中继设备发送的第二信息。In step S62, second information sent by the relay device is received based on the PUCCH resource.

在一些实施例中，网络设备可以基于S61中资源指示信息所指示的PUCCH资源接收中继设备发送的第二信息。In some embodiments, the network device may receive the second information sent by the relay device based on the PUCCH resource indicated by the resource indication information in S61.

例如，网络设备向中继设备发送一个或多个资源指示信息，网络设备可以在最后一次发送的资源指示信息所指示的PUCCH资源上，接收中继设备发送的第二信息。又例如，网络设备以在任意第N次发送资源指示信息所指示的PUCCH资源上，接收中继设备发送的第二信息，本公开不作限定。For example, the network device sends one or more resource indication information to the relay device, and the network device can receive the second information sent by the relay device on the PUCCH resource indicated by the resource indication information sent last. For another example, the network device receives the second information sent by the relay device on the PUCCH resource indicated by any Nth sending of the resource indication information, which is not limited in this disclosure.

本公开提供了发送HARQ反馈信息的PUCCH资源确定方式，以便在包括侧控制信息的DCI的HARQ反馈可以与其它HARQ反馈进行复用的情况下，可以选择相应的PUCCH发送相应HARQ反馈信息，使得不同信令可以支持不同的反馈方式。进而保证相应信令的正确接收，提升通信系统的鲁棒性。The present disclosure provides a PUCCH resource determination method for sending HARQ feedback information, so that when the HARQ feedback of the DCI including the side control information can be multiplexed with other HARQ feedbacks, the corresponding PUCCH can be selected to send the corresponding HARQ feedback information, so that different signaling can support different feedback methods, thereby ensuring the correct reception of the corresponding signaling and improving the robustness of the communication system.
