数据传输的方法和装置Method and device for data transmission

技术领域technical field

本申请涉及通信领域，并且更具体地，涉及一种数据传输的方法和装置。The present application relates to the communication field, and more specifically, to a data transmission method and device.

背景技术Background technique

为了解决日益增长的通信需求，高频(6G以上频段，主要包括28G、39G、60G、73G等)因其丰富的频谱资源成为业界研究和开发的热点。特别是52.6～71G这段频谱，其显著特点为大带宽，为了充分利用这段频谱资源，提高峰值速率或吞吐，业界提出将单个载波所占用的带宽从现在新一代无线通信系统(new radio，NR)的400M增加至约2G或更高，同时由于终端的硬件等限制了波形调制过程中的快速傅里叶变换(fast fourier transformation，FFT)点数，因此，大子载波间隔如240k、480k、960k甚至1920k的研究被提出。In order to meet the growing communication needs, high frequency (frequency bands above 6G, mainly including 28G, 39G, 60G, 73G, etc.) has become a hot spot for research and development in the industry due to its rich spectrum resources. In particular, the 52.6-71G spectrum is characterized by large bandwidth. In order to make full use of this spectrum resource and increase the peak rate or throughput, the industry proposes to reduce the bandwidth occupied by a single carrier from the current new generation wireless communication system (new radio, NR) of 400M increases to about 2G or higher, and because the hardware of the terminal limits the number of fast Fourier transformation (fast fourier transformation, FFT) points in the waveform modulation process, therefore, large subcarrier intervals such as 240k, 480k, 960k and even 1920k studies were proposed.

但是，增大子载波间隔会导致时隙缩短，这对终端的处理能力提出了更高的要求。目前的一种解决方案为多时隙调度，此时以多时隙为单位检测/监测/盲检控制信道，且控制信道调度的共享信道在时间上也以多时隙为单位，即终端可以多个时隙检测一次控制信道，降低控制信道检测复杂度和功耗。However, increasing the subcarrier spacing will lead to shortening of the time slot, which puts forward higher requirements on the processing capability of the terminal. A current solution is multi-slot scheduling. At this time, the control channel is detected/monitored/blindly detected in units of multi-slots, and the shared channel of the control channel scheduling is also in units of multi-slots in time, that is, the terminal can use multiple time slots as a unit. The control channel is detected once every slot, which reduces the complexity and power consumption of control channel detection.

当上述多时隙调度应用至高频的单下行控制信息(downlink controlinformation，DCI)调度多个时隙的物理下行共享信道(physical downlink sharechannel，PDSCH)或物理上行共享信道(physical uplink share channel，PUSCH)，或单DCI调度多个PDSCH或PUSCH时，会使得DCI的负载增加较多，造成下行物理控制信道的覆盖降低。When the above multi-slot scheduling is applied to high-frequency single downlink control information (downlink control information, DCI) scheduling multiple time slots of physical downlink shared channel (physical downlink shared channel, PDSCH) or physical uplink shared channel (physical uplink share channel, PUSCH) , or when a single DCI schedules multiple PDSCHs or PUSCHs, the load of the DCI will be increased considerably, resulting in a decrease in the coverage of the downlink physical control channel.

第一方面，提供了一种数据传输的方法，包括：网络设备向终端设备发送下行控制信息DCI，DCI用于调度至少一个物理共享信道，DCI包括第一信息，第一信息用于联合指示至少一个物理共享信道的新数据指示NDI信息和冗余版本RV信息；网络设备根据第一信息与终端设备进行数据传输。In a first aspect, a data transmission method is provided, including: a network device sends downlink control information DCI to a terminal device, the DCI is used to schedule at least one physical shared channel, the DCI includes first information, and the first information is used to jointly indicate at least The new data of a physical shared channel indicates NDI information and redundancy version RV information; the network device performs data transmission with the terminal device according to the first information.

根据本申请的技术方案，通过联合指示物理共享信道的NDI信息和RV信息，有助于降低DCI的负载，保证PDCCH的覆盖。According to the technical solution of the present application, by jointly indicating the NDI information and the RV information of the physical shared channel, it is helpful to reduce the load of the DCI and ensure the coverage of the PDCCH.

其中，网络设备根据第一信息与终端设备进行数据传输包括上行数据传输和下行数据传输。上行数据传输时，终端设备为数据的发送方，网络设备为数据的接收方；下行数据传输时，网络设备为数据的发送方，终端设备为数据的接收方。Wherein, the data transmission between the network device and the terminal device according to the first information includes uplink data transmission and downlink data transmission.

其中，当第一子集和/或第二子集有且仅有一个元素(即，只包括一个RV)时，不需要额外的信息指示具体的RV，因此此时NDI联合指示或隐式指示或间接指示的RV信息为全部的RV信息；当第一子集和/或第二子集的元素数大于1且小于或等于4时，需要额外的信息指示子集中具体的RV信息，此时NDI联合指示或隐式指示或间接指示的RV信息为部分RV信息。Wherein, when the first subset and/or the second subset have one and only one element (that is, only include one RV), no additional information is required to indicate a specific RV, so at this time NDI joint indication or implicit indication Or the RV information indirectly indicated is all RV information; when the number of elements in the first subset and/or the second subset is greater than 1 and less than or equal to 4, additional information is required to indicate the specific RV information in the subset, at this time The RV information jointly indicated by NDI or implicitly indicated or indirectly indicated is partial RV information.

结合第一方面，在第一方面的某些实现方式中，上述方法还包括：网络设备发送无线资源控制RRC消息，RRC消息用于指示第一RV集合，第一RV集合包括第一信息指示的RV信息对应的RV。With reference to the first aspect, in some implementations of the first aspect, the above method further includes: the network device sends a radio resource control RRC message, the RRC message is used to indicate the first RV set, and the first RV set includes the information indicated by the first information. The RV corresponding to the RV information.

结合第一方面，在第一方面的某些实现方式中，RRC消息用于指示多个RV集合，上述方法还包括：网络设备发送媒体接入控制MAC信息，MAC信息用于指示多个RV集合中的第一RV集合。With reference to the first aspect, in some implementations of the first aspect, the RRC message is used to indicate multiple RV sets, and the above method further includes: the network device sends media access control MAC information, and the MAC information is used to indicate multiple RV sets 1st RV collection in.

根据本申请的技术方案，通过RRC消息发送冗余版本集合的信息，与DCI信息相结合，可以同时实现冗余版本的灵活配置以及减少冗余版本指示的负载。According to the technical solution of the present application, the information of the redundancy version set is sent through the RRC message, and combined with the DCI information, the flexible configuration of the redundancy version and the reduction of the load of the redundancy version indication can be realized at the same time.

结合第一方面，在第一方面的另一些实现方式中，上述至少一个物理共享信道包括多个物理共享信道，第一信息还用于同时指示多个物理共享信道的数据均为初传数据或重传数据。其中，第一信息的大小为1比特。With reference to the first aspect, in some other implementation manners of the first aspect, the above-mentioned at least one physical shared channel includes multiple physical shared channels, and the first information is also used to simultaneously indicate that the data of the multiple physical shared channels are all initial transmission data or Retransmit data. Wherein, the size of the first information is 1 bit.

结合第一方面，在第一方面的另一些实现方式中，DCI还包括第二信息，第二信息用于指示多个物理共享信道中的首个物理共享信道的HARQ进程。With reference to the first aspect, in some other implementation manners of the first aspect, the DCI further includes second information, and the second information is used to indicate the HARQ process of the first physical shared channel among the multiple physical shared channels.

结合第一方面，在第一方面的另一些实现方式中，当多个物理共享信道的数据均为初传数据时，除用于初传数据的物理共享信道的首个HARQ进程之外的其他用于初传数据的所述物理共享信道的HARQ进程为基于指示的HARQ进程依次加一。In combination with the first aspect, in some other implementation manners of the first aspect, when the data of multiple physical shared channels are all initially transmitted data, other than the first HARQ process of the physical shared channel used for initially transmitted data The HARQ process of the physical shared channel used for initial data transmission is the indication-based HARQ process plus one in sequence.

进一步地，由于HARQ进程不是无限制增加的，目前NR协议中，HARQ进程的总数量为32、16或者64，即HARQ进程的取值范围为0～32、0～15或者0～63，因此当传输的PDSCH数量超过32(或者16或者64)后，会重新从0开始计数，并依据此规律进行循环。示例性的，假设重传对应的HARQ进程集合为空集，调度的第i+1个物理共享信道的HARQ进程可以是mod(A+i，M)，其中，A为上述第二信息所指示的HARQ进程，M为HARQ进程的总数量，如32、16或者64。Further, since the HARQ process is not unlimitedly increased, in the current NR protocol, the total number of HARQ processes is 32, 16 or 64, that is, the value range of the HARQ process is 0-32, 0-15 or 0-63, so When the number of transmitted PDSCHs exceeds 32 (or 16 or 64), it will restart counting from 0, and cycle according to this rule. Exemplarily, assuming that the HARQ process set corresponding to the retransmission is an empty set, the HARQ process of the i+1th physical shared channel scheduled may be mod(A+i, M), where A is indicated by the above-mentioned second information HARQ processes, M is the total number of HARQ processes, such as 32, 16 or 64.

结合第一方面，在第一方面的另一些实现方式中，当多个物理共享信道的数据均为重传数据时，多个物理共享信道中的除首个物理共享信道之外的物理共享信道的HARQ进程从重传HARQ进程集合中按照时间顺序依次确定。With reference to the first aspect, in some other implementation manners of the first aspect, when the data of multiple physical shared channels are all retransmission data, the physical shared channels of the multiple physical shared channels except the first physical shared channel The HARQ processes are determined sequentially from the retransmission HARQ process set in chronological order.

根据本申请的技术方案，当单个DCI调度的多个物理共享信道均用于初传或者重传数据时，增加一个比特可以联合指示该DCI调度的全部物理共享信道均用于初传或者重传数据，替代每个物理共享信道对应的NDI域，显著减少了多个物理共享信道的NDI指示比特数。According to the technical solution of this application, when multiple physical shared channels scheduled by a single DCI are used for initial transmission or retransmission of data, adding one bit can jointly indicate that all physical shared channels scheduled by the DCI are used for initial transmission or retransmission The data replaces the NDI field corresponding to each physical shared channel, and significantly reduces the number of NDI indication bits of multiple physical shared channels.

结合第一方面，在第一方面的又一些实现方式中，上述至少一个物理共享信道包括多个物理共享信道，多个物理共享信道包括用于初传数据的物理共享信道和用于重传数据的物理共享信道，DCI还包括第三信息，第三信息用于指示用于重传数据的物理共享信道的数量。With reference to the first aspect, in still some implementation manners of the first aspect, the at least one physical shared channel includes multiple physical shared channels, and the multiple physical shared channels include a physical shared channel for initial data transmission and a physical shared channel for retransmission data. The DCI further includes third information, where the third information is used to indicate the number of physical shared channels used for retransmitting data.

可选地，第三信息还可以用于指示用于初传数据的物理共享信道的数量。这样，通过计算也可以得知用于重传数据的物理共享信道的数量。Optionally, the third information may also be used to indicate the number of physical shared channels used for initial data transmission.

结合第一方面，在第一方面的又一些实现方式中，DCI还包括第四信息，第四信息用于指示用于重传数据的物理共享信道中的首个物理共享信道的HARQ进程。With reference to the first aspect, in still some implementation manners of the first aspect, the DCI further includes fourth information, and the fourth information is used to indicate the HARQ process of the first physical shared channel among the physical shared channels used for retransmitting data.

结合第一方面，在第一方面的又一些实现方式中，除用于重传数据的首个物理共享信道HARQ进程之外的其他用于重传数据的物理共享信道的HARQ进程从重传HARQ进程集合中按照时间顺序依次确定；用于初传数据的首个物理共享信道的HARQ进程为指示的HARQ进程后且不包含在重传HARQ进程集合中的第一个HARQ进程，除用于初传数据的首个物理共享信道之外的其他用于初传数据的物理共享信道的HARQ进程基于首个初传的物理共享信道的HARQ进程，依次加一。In combination with the first aspect, in still some implementations of the first aspect, except for the first physical shared channel HARQ process used for retransmitting data, the HARQ processes of other physical shared channels used for retransmitting data start from the retransmission HARQ process The set is determined in chronological order; the HARQ process of the first physical shared channel used for the initial data transmission is the first HARQ process after the indicated HARQ process and not included in the retransmission HARQ process set, except for the initial transmission The HARQ processes of other physical shared channels other than the first data physical shared channel used for initial data transmission are based on the HARQ process of the first initial physical shared channel, and are sequentially incremented by one.

其中，其他用于初传数据的物理共享信道的HARQ进程可以用公式mod(A+k,M)表示，其中，A为上述第四信息所指示的HARQ进程，M为HARQ进程的总数量，如32、16或者64，k为使得mod(A+k，M)不属于重传对应的HARQ进程集合中的最小正整数。Wherein, other HARQ processes of the physical shared channel used for initial data transmission can be represented by the formula mod(A+k,M), wherein, A is the HARQ process indicated by the fourth information above, and M is the total number of HARQ processes, Such as 32, 16 or 64, k is the minimum positive integer that makes mod(A+k, M) not belong to the HARQ process set corresponding to the retransmission.

根据本申请的技术方案，通过重新定义单个DCI调度的多个物理共享信道中用于重传的物理共享信道和用于初传的物理共享信道的位置分布，将用于重传或初传的物理共享信道集中传输，在DCI中增加域用于指示单个DCI调度的多个物理共享信道中用于重传的物理共享信道的数量，替代每个物理共享信道对应的NDI域，显著减少了多个物理共享信道的NDI指示比特数，降低了DCI的负责，提升了PDCCH的覆盖。According to the technical solution of this application, by redefining the position distribution of the physical shared channel used for retransmission and the physical shared channel used for initial transmission among the multiple physical shared channels scheduled by a single DCI, the physical shared channel used for retransmission or initial transmission Centralized transmission of physical shared channels, adding fields in DCI to indicate the number of physical shared channels used for retransmission in multiple physical shared channels scheduled by a single DCI, replacing the NDI field corresponding to each physical shared channel, significantly reducing multiple The number of NDI indication bits of a physical shared channel reduces the burden of DCI and improves the coverage of PDCCH.

其中，上述差分值的步进值为一固定值或者或非固定值。Wherein, the step value of the above-mentioned difference value is a fixed value or a non-fixed value.

例如，上述差分值可以为N*ΔMCS，或者SUM_i＝0,…,N(ΔMCS_i)，其中，N为非负整数，i越大，ΔMCS_i的绝对值越大。For example, the above differential value may be N*ΔMCS, or SUM_i=0,...,N (ΔMCS_i ), where N is a non-negative integer, and the larger i is, the larger the absolute value of ΔMCS_i is.

根据本申请的技术方案，当DCI调度的物理共享信道包括多个码字时，在DCI中增加域用于指示物理共享信道多个码字的NDI信息，替代每个码字对应的NDI域，显著减少了多个码字的NDI指示比特数，进一步地，第二个码字的MCS可以通过第一个码字的MCS值和两个MCS值之间的差分值指示，可以进一步地减少DCI的负载，提升PDCCH的覆盖。According to the technical solution of the present application, when the physical shared channel scheduled by the DCI includes multiple codewords, a field is added to the DCI to indicate the NDI information of multiple codewords of the physical shared channel, replacing the NDI field corresponding to each codeword, The number of NDI indication bits of multiple codewords is significantly reduced.

为便于理解本申请实施例，下面对本申请实施例涉及的概念进行解释。To facilitate understanding of the embodiments of the present application, concepts involved in the embodiments of the present application are explained below.

1、冗余版本(redundancy version，RV)1. Redundancy version (RV)

在编码过程中，原始信源比特(A个比特)会以1/3的码率编码得到母码(3A个比特)，然后根据实际码率按照某种规则从母码中选择部分比特(长度为B，B由实际码率决定，约为A/CodeRate，下文以编码比特集代替)作为最终的编码结果用于调制、映射等。如图2所示，阴影部分为原始信源比特，整个圆环为母码，一个箭头所包括的部分则为某次传输的实际比特。其中不同的箭头即表示不同的冗余版本。In the encoding process, the original source bits (A bits) will be coded at a code rate of 1/3 to obtain the mother code (3A bits), and then some bits (length is B, B is determined by the actual code rate, which is about A/CodeRate, hereinafter replaced by the coded bit set) as the final coding result for modulation, mapping, etc. As shown in Figure 2, the shaded part is the original source bit, the entire circle is the mother code, and the part included by an arrow is the actual bit of a certain transmission. Different arrows indicate different redundancy versions.

在数据传输过程中，会有部分数据因为信道条件等导致传输错误，此时需要重传错误的数据包，保证接收端的数据接收完整性。重传必须发送与初传相同的码块(codeblock，CB)或传输块(transmission block，TB)，但是每次重传可以选择不同的编码比特集，只要这些编码比特代表相同的CB或TB。在新一代无线通信系统NR中，根据重传的比特信息与初传是否相同，软合并方案分为追逐合并(chase combining，CC)和增量冗余(incremental redundancy，IR)。追逐合并中重传的比特信息与初传相同(即发送相同的灰色箭头对应的编码比特集)，增量冗余中重传的比特信息不需要与初传相同。During the data transmission process, some data may be transmitted incorrectly due to channel conditions, etc. At this time, it is necessary to retransmit the wrong data packets to ensure the integrity of the data reception at the receiving end. The retransmission must send the same codeblock (CB) or transmission block (TB) as the initial transmission, but each retransmission can choose a different set of coded bits, as long as these coded bits represent the same CB or TB. In the new generation wireless communication system NR, according to whether the retransmitted bit information is the same as the initial transmission, soft combining schemes are divided into chase combining (CC) and incremental redundancy (IR). The retransmitted bit information in chase combining is the same as the initial transmission (that is, the same coded bit set corresponding to the gray arrow is sent), and the retransmitted bit information in incremental redundancy does not need to be the same as the initial transmission.

在追逐合并中，发送方将原始信息比特加上循环冗余校验(cyclic redundancycheck，CRC)后通过编码产生编码比特集，无论初传还是重传都要发送这个编码比特集。每次重传信息都与初传相同，可以提升信噪比。In chase combining, the sender adds a cyclic redundancy check (CRC) to the original information bits to generate a coded bit set through encoding, and the coded bit set must be sent regardless of initial transmission or retransmission. Each retransmission information is the same as the initial transmission, which can improve the signal-to-noise ratio.

在增量冗余中，每一次重传并不需要与初传相同。相反，会生成多个编码比特集，每个集合都携带相同的信息。每当需要重传时，通常会传输与前一次不同的编码比特集，接收端会把重传的数据与前一次传输的数据进行合并。每次重传的编码比特集称为一个RV。增量冗余通过重传来发送额外的冗余信息，随着重传次数的增加，冗余信息不断累积，信道编码效率不断降低，从而获得更好的译码效果。In incremental redundancy, each retransmission does not need to be the same as the initial transmission. Instead, multiple sets of coded bits are generated, each carrying the same information. Whenever a retransmission is required, a different coded bit set than the previous one is usually transmitted, and the receiving end will combine the retransmitted data with the previous transmitted data. The coded bit set for each retransmission is called an RV. Incremental redundancy sends additional redundant information through retransmission. As the number of retransmissions increases, redundant information accumulates and channel coding efficiency decreases, thereby obtaining better decoding results.

结合上述描述，从图中可以看出，RV0包含了全部的系统比特，RV3包含了大部分系统比特，所以RV0和RV3传输的编码比特集可以支持自解码，即在仅传输了RV0或RV3时，二者均有较高概率恢复出原始比特，而RV1和RV2包含大部分或全部都是校验比特，所以无法自解码，必须结合RV0或RV3的编码比特集，才能正确译码。Combined with the above description, it can be seen from the figure that RV0 contains all the systematic bits, and RV3 contains most of the systematic bits, so the coded bit sets transmitted by RV0 and RV3 can support self-decoding, that is, when only RV0 or RV3 is transmitted , both have a high probability of recovering the original bits, and RV1 and RV2 contain most or all of the check bits, so they cannot be self-decoded, and must be combined with the coded bit set of RV0 or RV3 to decode correctly.

2、多时隙调度2. Multi-slot scheduling

现有NR系统中共享信道的调度、控制信道的检测周期、混合自动重传请求(hybridautomatic repeat request，HARQ)进程等均与子载波间隔有关，如共享信道的调度单位在时间上是时隙(14个OFDM符号)或迷你时隙(2～13个OFDM符号)，时隙的持续时间由子载波间隔确定，子载波间隔越大，时隙的持续时间越短，如图3所示，其中一个矩形框表示一个时隙，由图可知，子载波为120k的一个时隙内可分别包含240k的2个时隙、480k的4个时隙、960k的8个时隙。控制信道的检测频率也是时隙。因此当数据子载波间隔从现有NR系统中的120k增加至480k或960k时，480k或960k对应的时隙时间会缩短至120k的时隙时间的1/4或1/8，若此时仍以时隙为单位检测控制信道，对终端的处理能力将是一个巨大的挑战。因此，针对大子载波间隔时隙缩短的问题，其中一种解决方案为多时隙调度，此时共享信道和控制信道在时间上均以多时隙为单位进行调度，即终端可以多个时隙检测一次控制信道，以期望降低控制信道检测复杂度和功耗。In the existing NR system, the scheduling of the shared channel, the detection period of the control channel, and the hybrid automatic repeat request (HARQ) process are all related to the subcarrier spacing. For example, the scheduling unit of the shared channel is a time slot ( 14 OFDM symbols) or mini-slots (2 to 13 OFDM symbols), the duration of the time slot is determined by the subcarrier spacing, the larger the subcarrier spacing, the shorter the duration of the time slot, as shown in Figure 3, one of The rectangular frame represents a time slot. It can be seen from the figure that a time slot with a subcarrier of 120k can include 2 time slots of 240k, 4 time slots of 480k, and 8 time slots of 960k. The detection frequency of the control channel is also a time slot. Therefore, when the data subcarrier spacing is increased from 120k in the existing NR system to 480k or 960k, the time slot time corresponding to 480k or 960k will be shortened to 1/4 or 1/8 of the time slot time of 120k. Detecting the control channel in units of time slots will pose a huge challenge to the processing capability of the terminal. Therefore, one solution to the problem of shortening time slots with large subcarrier intervals is multi-slot scheduling. At this time, both the shared channel and the control channel are scheduled in units of multi-slots in time, that is, the terminal can detect multiple time slots. A control channel is expected to reduce control channel detection complexity and power consumption.

目前，NR协议中定义了两种多时隙调度的传输块映射方法，一种是在多个时隙内多次传输同一个传输块，一种是多个时隙内传输多个不同传输块。第一种方法中的同一个传输块在多次传输中有不同的冗余版本，接收端对同一个传输块多个冗余版本合并解调，增强覆盖；第二种方法一次传输多个不同的传输块，可以减少下行控制信息(downlinkcontrol information，DCI)的检测次数的同时，维持高的吞吐。当一个DCI调度多个(如N_pusch个)PUSCH，且不同PUSCH承载不同的TB时，相比调度单PUSCH承载单个TB，有以下几个区别点：Currently, two transmission block mapping methods for multi-slot scheduling are defined in the NR protocol. One is to transmit the same transmission block multiple times in multiple time slots, and the other is to transmit multiple different transmission blocks in multiple time slots. In the first method, the same transmission block has different redundant versions in multiple transmissions, and the receiving end combines and demodulates multiple redundant versions of the same transmission block to enhance coverage; the second method transmits multiple different redundancy versions at one time. The transmission blocks can reduce the number of downlink control information (DCI) detections while maintaining high throughput. When a DCI schedules multiple (such as N_pusch ) PUSCHs, and different PUSCHs carry different TBs, compared with scheduling a single PUSCH to carry a single TB, there are the following differences:

(1)新数据指示(new data indicator，NDI)域的负载从1个比特增加为N_pusch个比特：每个比特对应一个PUSCH，用于指示初传或重传。(1) The load of the new data indicator (new data indicator, NDI) field is increased from 1 bit to N_pusch bits: each bit corresponds to a PUSCH, and is used to indicate initial transmission or retransmission.

(2)RV域的负载从2个比特增加为N_pusch个比特：每个比特对应一个PUSCH，用于指示PUSCH的RV版本。(2) The load of the RV field is increased from 2 bits to N_pusch bits: each bit corresponds to a PUSCH, and is used to indicate the RV version of the PUSCH.

a)当调度单个PUSCH时，单个PUSCH的TB的冗余版本可以是RV0～RV3中任一种，因此需要2个比特指示冗余版本，其指示的冗余版本如下表1所示：a) When scheduling a single PUSCH, the redundancy version of the TB of a single PUSCH can be any of RV0-RV3, so 2 bits are required to indicate the redundancy version, and the redundancy version indicated is shown in Table 1 below:

表1 DCI调度单个PUSCH时所指示的冗余版本情况表Table 1 Table of redundancy versions indicated when DCI schedules a single PUSCH

冗余版本字段的值The value of the redundant version field应用的冗余版本RVApplied redundant version RV000000010111101022111133

b)当调度多个PUSCH时，为了降低RV域的整体负载，每个PUSCH改为一个比特指示冗余版本，具体的指示信息如下表2所示：b) When scheduling multiple PUSCHs, in order to reduce the overall load of the RV domain, each PUSCH is changed to a bit to indicate the redundancy version. The specific indication information is shown in Table 2 below:

冗余版本字段的值The value of the redundant version field应用的冗余版本RVAppliedredundant version RV00001122

另外，当DCI调度单PDSCH，单PDSCH上承载多个TB时，如调度层数大于4时，需在多层上映射两个独立的码字，前ceil(Nlayer/2)上映射第一个码字，后floor(Nlayer/2)上映射第二个码字，其中Nlayer为调度层数，ceil(x)表示对x向上取整，floor(x)表示对x向下取整。In addition, when DCI schedules a single PDSCH and multiple TBs are carried on a single PDSCH, if the number of scheduling layers is greater than 4, two independent codewords need to be mapped on multiple layers, and the first one is mapped on the front ceil (Nlayer/2) After the codeword, the second codeword is mapped to floor(Nlayer/2), where Nlayer is the number of scheduling layers, ceil(x) means to round up x, and floor(x) means to round down x.

在调度层数大于4时引入两个码字的原因即不同层上的信道质量相差较大，一个码字不能很好匹配不同层上的信道，因此通过两个码字可以分别引入两个调制编码方式，分别匹配不同质量的信道。因此，相比DCI调度单PDSCH且调度层数小于等于4时，调度单PDSCH且调度层数大于4的DCI格式有以下变化：The reason for introducing two codewords when the number of scheduling layers is greater than 4 is that the channel quality on different layers is quite different, and one codeword cannot well match the channels on different layers. Therefore, two codewords can be used to introduce two modulations respectively. The encoding method matches channels with different qualities respectively. Therefore, compared with DCI scheduling a single PDSCH and the number of scheduling layers is less than or equal to 4, the DCI format that schedules a single PDSCH and the number of scheduling layers is greater than 4 has the following changes:

(1)调制和编码方案(modulation and coding scheme，MCS)指示域由5比特增加为10比特：每个码字或TB(单PDSCH时一个码字即对应一个TB)对应5比特，用于指示每个码字的MCS。(1) The modulation and coding scheme (MCS) indication field is increased from 5 bits to 10 bits: each codeword or TB (one codeword corresponds to one TB in the case of a single PDSCH) corresponds to 5 bits, which are used to indicate MCS for each codeword.

(2)NDI域由1比特增加为2比特：每个码字或TB对应一个比特，用于指示是初传还是重传。(2) The NDI field is increased from 1 bit to 2 bits: each codeword or TB corresponds to one bit, which is used to indicate whether it is initial transmission or retransmission.

(3)RV域由2比特增加为4比特：每个码字或TB对应2个比特，用于指示当前传输的码字或TB的冗余版本。(3) The RV field is increased from 2 bits to 4 bits: each codeword or TB corresponds to 2 bits, which are used to indicate the redundancy version of the currently transmitted codeword or TB.

当目前NR协议中的方案直接扩展至高频的单DCI调度多个时隙的PDSCH或PUSCH，或单DCI调度多个PDSCH或PUSCH时，会使得DCI的负载增加较多，造成下行物理控制信道的覆盖降低，如以单DCI调度单个PDSCH且调度单码字为基准，单DCI调度8个PDSCH/PUSCH和/或调度双码字时增加的负载分别如下表所示：When the solution in the current NR protocol is directly extended to high-frequency single DCI scheduling PDSCH or PUSCH with multiple time slots, or single DCI scheduling multiple PDSCH or PUSCH, the load of DCI will increase greatly, causing downlink physical control channel For example, based on a single DCI scheduling a single PDSCH and scheduling a single codeword, the increased load when asingle DCI schedules 8 PDSCH/PUSCH and/or double codewords is shown in the following table:

其中“8”是目前NR协议中允许的单DCI调度的PDSCH的最大数量。由上表可以看出，单DCI调度多时隙和/或单DCI调度双码字(每个PDSCH)均导致负载增加了较多，特别是同时调度多PDSCH/PUSCH和双码字的场景，假设DCI的总负载为100比特，其增加了30％+的负载，在相同的物理下行控制信道(physical downlink control channel，PDCCH)资源下，等效的码率会增加，对PDCCH的覆盖造成很严峻的压力。Where "8" is the maximum number of PDSCHs scheduled by a single DCI allowed in the current NR protocol. As can be seen from the above table, single DCI scheduling multiple time slots and/or single DCI scheduling double codewords (each PDSCH) will lead to a large increase in load, especially in the scenario where multiple PDSCH/PUSCH and double codewords are scheduled at the same time, assuming The total load of DCI is 100 bits, which increases the load by 30%. Under the same physical downlink control channel (physical downlink control channel, PDCCH) resources, the equivalent code rate will increase, causing serious problems to the coverage of PDCCH pressure.

基于此，针对单DCI调度多PDSCH/PUSCH和/或双码字的场景，提出一种新的数据传输的指示方法，可以降低DCI的负载，保证PDCCH的覆盖。Based on this, for the scenario where multiple PDSCH/PUSCH and/or double codewords are scheduled by a single DCI, a new data transmission indication method is proposed, which can reduce the load of DCI and ensure the coverage of PDCCH.

可选地，当个物理共享信道的数据均为重传数据时，除用于重传数据的首个物理共享信道HARQ进程之外的其他用于重传数据的物理共享信道的HARQ进程从重传HARQ进程集合中按照时间顺序依次确定。Optionally, when the data of each physical shared channel is retransmission data, the HARQ processes of other physical shared channels used for retransmission data except for the first physical shared channel HARQ process used for retransmission data start from the retransmission The HARQ process set is sequentially determined according to time sequence.

在本申请实施例的再一种可能的实现方式中，上述至少一个物理共享信道还可以包括多个物理共享信道，多个物理共享信道可以包括用于初传数据的物理共享信道和用于重传数据的物理共享信道，此时，上述DCI还可以包括第三信息，第三信息用于指示用于重传数据的物理共享信道的数量。In yet another possible implementation manner of the embodiment of the present application, the above-mentioned at least one physical shared channel may also include multiple physical shared channels, and the multiple physical shared channels may include a physical shared channel for initial data transmission and a physical shared channel for A physical shared channel for data transmission.

如图5所示，HARQ进程总数为32，假设用于重传数据的物理共享信道中的首个物理共享信道的HARQ进程为HARQ 0，则用于初传数据的首个物理共享信道的HARQ进程为以HARQ0为起点(不包括HARQ 0)，按照顺时针顺序，且不在或不属于重传HARQ进程集合中的第一个HARQ进程。As shown in Figure 5, the total number of HARQ processes is 32.

图6示出了本申请数据传输方法的具体示例的一例示意性流程图。Fig. 6 shows a schematic flowchart of a specific example of the data transmission method of the present application.

S401，终端设备102接收来自网络设备101的RRC消息，该RRC消息包括RV版本信息。S401, theterminal device 102 receives an RRC message from thenetwork device 101, where the RRC message includes RV version information.

具体地，网络设备101可以在PDSCH/PUSCH(以下将以物理共享信道同时指示PDSCH/PUSCH)的配置中增加信息：定义一个或多个RV集合(或者列表)，每个RV集合中可以包含1种或2种或4种冗余版本，当包含多个RV时，不同的RV集合可以有不同的RV，或有相同的RV冗余版本和不一样的RV顺序。以RV集合举例如下：Specifically, thenetwork device 101 can add information to the configuration of PDSCH/PUSCH (hereinafter, PDSCH/PUSCH will be indicated as a physical shared channel): define one or more RV sets (or lists), and each RV set can contain 1 One or two or four redundancy versions. When multiple RVs are included, different RV sets can have different RVs, or have the same RV redundancy version but different RV sequences. Take the RV set as an example as follows:

假设有X_RV个RV集合{RVset_{_0},RVset_{_1}，……，RVset_{_XRV-1}}，X_RV为正整数，其中，X_RV个RV集合中的RV集合i，即RVset_{_i}包含2个RV，如RVset_{_i}＝{RV0，RV2}；RV集合j即RVset_{_j}包含4个RV，如RVset_{_j}＝{RV0，RV2，RV3，RV1}，RV集合k即RVset_{_k}包含2个RV，如RVset_{_k}＝{RV0，RV3}，RV集合l即RVset_{_l}包含4个RV，如RVset_{_l}＝{RV0，RV3，RV2，RV1}，其中i、j、k、l为满足0<＝i、j、k、l<X_RV的整数。Suppose there are X_RV sets of RV {_{RVset_0} ,_{RVset_1} , ...,_{RVset_XRV-1} }, X_RV is a positive integer, wherein, RV set i in the X_RV sets of RVs, that is,_{RVset_i} contains 2 RVs, Such as_{RVset_i} = {RV0, RV2}; RV set j, that is,_{RVset_j} contains 4 RVs, such as_{RVset_j} = {RV0, RV2, RV3, RV1}, RV set k, that is,_{RVset_k} contains 2 RVs, such as_{RVset_k} = {RV0, RV3}, RV set 1, that is,_{RVset_l} contains 4 RVs, such as_{RVset_l} = {RV0, RV3, RV2, RV1}, wherein i, j, k, l satisfy 0<=i, j, k, Integer of l<X_RV .

可选地，网络设备101在定义RV集合(或列表)时可以复用现有的分组，例如，在时域资源分配(Time domain resource allocation，TDRA)表格中针对每一行定义一个RV集合，其中，TDRA表格中的一行表示一种调度，可以包括一个或多个物理共享信道，调度的物理共享信道的数量可以由该行起始和长度指示值(start and length indicator value，SLIV)的数量确定，每个SLIV对应一个物理共享信道在时隙内的时域资源分配情况，RV集合中的RV的数量和TDRA表格中该行的SLIV数量有关。优选地，SLIV数量增加，RV集合中RV数量减少，如SLIV数量为1时，RV集合包含4个RV，SLIV数量大于1小于或等于4时，RV集合包含2个RV，SLIV数量大于或等于4时，RV集合包含1个RV。Optionally, thenetwork device 101 may reuse existing packets when defining an RV set (or list), for example, define an RV set for each row in a time domain resource allocation (TDRA) table, where , a row in the TDRA table represents a scheduling, which can include one or more physical shared channels, and the number of scheduled physical shared channels can be determined by the number of start and length indicator values (SLIV) of the row , each SLIV corresponds to the time-domain resource allocation of a physical shared channel in a time slot, and the number of RVs in the RV set is related to the number of SLIVs in this row in the TDRA table. Preferably, the number of SLIVs increases and the number of RVs in the RV set decreases. For example, when the number of SLIVs is 1, the RV set contains 4 RVs; when the number of SLIVs is greater than 1 and less than or equal to 4, the RV set contains 2 RVs, and the number of SLIVs is greater than or equal At 4, the RV set contains 1 RV.

S402，终端设备102接收网络设备发送的DCI信息，该DCI信息包括第一信息，第一信息用于联合指示至少一个物理共享信道的NDI信息和/或RV信息。S402. Theterminal device 102 receives DCI information sent by the network device, where the DCI information includes first information, and the first information is used to jointly indicate NDI information and/or RV information of at least one physical shared channel.

当X_RV＝1时，具体的RV信息可由DCI直接或间接(显示或隐式)指示；可选地，当X_RV>1时，网络设备101可以通过媒体接入控制(medium access control，MAC)激活其中一个RV集合(可称为第一RV集合)，然后再由DCI直接或间接(显示或隐式)指示第一RV集合中的具体的RV信息。例如，网络设备101通过MAC激活上述RV集合i即RVset_{_i}＝{RV0，RV2}，则DCI可以基于该RVset_{_i}指示具体的RV为RV0或者RV2；又例如，MAC激活上述RV集合j即RVset_{_j}＝{RV0，RV2，RV3，RV1}，则DCI可以基于RVset_{_j}指示具体的RV为RV0或者RV2或者RV3或者RV1。When X_RV =1, the specific RV information can be directly or indirectly (explicitly or implicitly) indicated by DCI; optionally, when X_RV >1, thenetwork device 101 can use medium access control (medium access control, MAC ) to activate one of the RV sets (may be referred to as the first RV set), and then the DCI directly or indirectly (explicitly or implicitly) indicates specific RV information in the first RV set. For example, thenetwork device 101 activates the above-mentioned RV set i through MAC, that is,_{RVset_i} = {RV0, RV2}, then the DCI can indicate that the specific RV is_RV0 or RV2 based on the RVset_i; for another example, the MAC activates the above-mentioned RV set j, that is,_{RVset_j} ={RV0, RV2, RV3, RV1}, then the DCI can indicate that the specific RV is_RV0 or RV2 or RV3 or RV1 based on RVset_j.

根据本申请的技术方案，通过RRC消息发送冗余版本集合的信息，与DCI信息相结合，可以同时实现冗余版本的灵活配置以及减少DCI中冗余版本指示的负载。例如，当单个DCI调度的物理共享信道的数量为N，且N大于4时，若第一RV集合中仅有一个RV，相比目前NR协议，DCI可以至少节省N个比特(在物理共享信道包括双码字时，可以减少N*2个比特)，若第一RV集合中有两个RV，但两个RV分别和初传、重传关联，则有相同的好处，即单码字时节省N个RV指示比特，有效降低了DCI的负载。According to the technical solution of the present application, the information of the redundancy version set is sent through the RRC message, and combined with the DCI information, the flexible configuration of the redundancy version and the reduction of the load of the redundancy version indication in the DCI can be realized at the same time. For example, when the number of physical shared channels scheduled by a single DCI is N, and N is greater than 4, if there is only one RV in the first RV set, compared with the current NR protocol, DCI can save at least N bits (in the physical shared channel When double codewords are included, N*2 bits can be reduced), if there are two RVs in the first RV set, but the two RVs are respectively associated with initial transmission and retransmission, then there is the same benefit, that is, when a single codeword N RV indication bits are saved, which effectively reduces the DCI load.

以下将按照物理共享信道的不同情况，对本申请的各种情形进行介绍：The following will introduce various situations of this application according to different situations of the physical shared channel:

在该情形下，第一信息用于联合指示物理共享信道的NDI信息和RV信息。下面将以RV的部分或全部信息与NDI绑定，可由NDI间接或隐式指示为例，对该情形进行详细说明。In this case, the first information is used to jointly indicate the NDI information and RV information of the physical shared channel. The following will take an example in which part or all of the information of the RV is bound to the NDI, which can be indirectly or implicitly indicated by the NDI, to describe this situation in detail.

例如，当待选择或待确认的RV数量为4个时，如确定的第一RV集合中包含4个RV时，可将RV分为两组，组1和组2，其中NDI指示一个物理共享信道的数据为初传数据时，则该物理共享信道的RV只能是组1中的一种，NDI指示该物理共享信道的数据为重传数据时，该物理共享信道的RV只能是组2中的一种，如组1＝{RV0，RV3}，组2＝{RV1，RV2}；此时，DCI中额外的RV指示仅需要一个比特即可，即一个比特确定该物理共享信道的RV是组1中的哪一种，或组2中的哪一种。For example, when the number of RVs to be selected or confirmed is 4, if the determined first RV set contains 4 RVs, the RVs can be divided into two groups,Group 1 andGroup 2, where NDI indicates a physical share When the channel data is initial transmission data, the RV of the physical shared channel can only be one ofgroup 1, and when the NDI indicates that the data of the physical shared channel is retransmission data, the RV of the physical shared channel can only be one ofgroup 1. 2, such asgroup 1={RV0, RV3},group 2={RV1, RV2}; at this time, only one bit is needed for the additional RV indication in the DCI, that is, one bit determines the physical shared channel Which one is the RV ingroup 1, or which one is ingroup 2.

又例如，当待选择或待确认的RV数量为2个时，如确定的第一RV集合中包含2个RV时，可直接由NDI间接或隐式指示或确定RV，如NDI指示一个物理共享信道的数据为初传数据时，该物理共享信道的RV为第一RV集合中的第一个RV，NDI指示该物理共享信道的数据为重传数据时，该物理共享信道的RV为第一RV集合中的第二个RV。For another example, when the number of RVs to be selected or confirmed is 2, if the determined first RV set contains 2 RVs, the RV can be directly or implicitly indicated or determined by NDI, for example, NDI indicates a physical share When the channel data is initial transmission data, the RV of the physical shared channel is the first RV in the first RV set, and when the NDI indicates that the data of the physical shared channel is retransmission data, the RV of the physical shared channel is the first Second RV in RV collection.

需要说明的是，上述以NDI隐式指示RV的方式为例，但本申请对其不作限定，本申请还可以用RV信息隐式指示NDI信息。例如，当DCI中的RV域指示一个物理共享信道的冗余版本为{RV0，RV3}中的一种时，则该物理共享信道的数据为初传数据，或该物理共享信道的NDI信息为初传，否则该物理共享信道的数据为重传数据。还可以结合上一次传输中指示的冗余版本一起联合判断，如上一次指示的冗余版本为RV0或者RV3，此次指示的冗余版本为RV1或者RV2，则确定此次的传输为重传，其中两次传输所基于的物理共享信道的HARQ进程相同。It should be noted that, the above-mentioned manner in which NDI implicitly indicates RV is taken as an example, but this application does not limit it, and this application may also use RV information to implicitly indicate NDI information. For example, when the RV field in the DCI indicates that the redundancy version of a physical shared channel is one of {RV0, RV3}, then the data of the physical shared channel is initial transmission data, or the NDI information of the physical shared channel is initial transmission, otherwise the data of the physical shared channel is retransmission data. It can also be jointly judged in conjunction with the redundancy version indicated in the previous transmission. If the redundancy version indicated last time is RV0 or RV3, and the redundancy version indicated this time is RV1 or RV2, then it is determined that this transmission is a retransmission. The HARQ process of the physical shared channel on which the two transmissions are based is the same.

当单个DCI调度的物理共享信道为N，且N大于1时，相比于目前NR协议，本申请的技术方案可以至少减少N个比特，特别地，当物理共享信道包括多码字时，可以减少更多比特。When the number of physical shared channels scheduled by a single DCI is N, and N is greater than 1, compared with the current NR protocol, the technical solution of this application can reduce at least N bits. In particular, when the physical shared channel includes multiple codewords, it can Cut more bits.

情形2：Scenario 2:

在该情形下，第一信息用于联合指示多个物理共享信道的NDI信息。此时，多个物理共享信道均用于初传或重传数据。In this case, the first information is used to jointly indicate NDI information of multiple physical shared channels. At this time, multiple physical shared channels are used for initial transmission or retransmission of data.

具体地，在DCI增加一个域，指示单DCI调度的多个物理共享信道是用于初传还是重传数据，此时仅需要一个比特，替代目前NR协议中每个物理共享信道均有一个比特指示该信道用于初传或重传数据。Specifically, a field is added to the DCI to indicate whether multiple physical shared channels scheduled by a single DCI are used for initial transmission or retransmission of data. At this time, only one bit is needed, instead of one bit for each physical shared channel in the current NR protocol. Indicates that the channel is used for initial transmission or retransmission of data.

可选地，若指示初传，则同时在DCI中指示第一个物理共享信道的HARQ进程，其他物理共享信道的HARQ进程依次加一。此外，若其中某个HARQ进程还未结束传输，如属于之前传输出错需要重传的物理共享信道，或某个HARQ进程属于重传对应的HARQ集合，则在进程依次加一时可以选择跳过该HARQ进程。Optionally, if initial transmission is indicated, the HARQ process of the first physical shared channel is indicated in the DCI at the same time, and the HARQ processes of other physical shared channels are sequentially incremented by one. In addition, if one of the HARQ processes has not completed the transmission, if it belongs to the physical shared channel that needs to be retransmitted due to a previous transmission error, or if a certain HARQ process belongs to the HARQ set corresponding to the retransmission, you can choose to skip the process when the process is incremented by one. HARQ process.

具体地，参照图5中的描述，用于初传数据的首个物理共享信道的HARQ进程为以DCI中指示的第一个物理共享信道的HARQ进程为起点(不包括该HARQ进程)，按照顺时针顺序，且不在重传HARQ进程集合中的第一个HARQ进程。Specifically, referring to the description in FIG. 5, the HARQ process of the first physical shared channel used for initial data transmission starts from the HARQ process of the first physical shared channel indicated in the DCI (excluding the HARQ process), according to In clockwise order, the first HARQ process that is not in the retransmission HARQ process set.

进一步地，由于HARQ进程不是无限制增加的，目前NR协议中，HARQ进程的总数量为32、16或者64，即HARQ进程的取值范围为0～32、0～15或者0～63，因此当传输的PDSCH数量超过32(或者16或者64)后，会重新从0开始计数，并依据此规律进行循环。示例性的，假设重传对应的HARQ进程集合为空集，调度的第i+1个物理共享信道的HARQ进程可以是mod(A+i，M)，其中，A为指示的HARQ进程，M为HARQ进程的总数量，如32、16或者64。Further, since the HARQ process is not unlimitedly increased, in the current NR protocol, the total number of HARQ processes is 32, 16 or 64, that is, the value range of the HARQ process is 0-32, 0-15 or 0-63, so When the number of transmitted PDSCHs exceeds 32 (or 16 or 64), it will restart counting from 0, and cycle according to this rule. Exemplarily, assuming that the set of HARQ processes corresponding to the retransmission is an empty set, the HARQ process of the scheduled i+1th physical shared channel may be mod(A+i, M), where A is the indicated HARQ process, and M is the total number of HARQ processes, such as 32, 16 or 64.

可选地，若指示重传，则同时在DCI中指示第一个重传物理共享信道的HARQ进程，其他物理共享信道的HARQ进程依次按时间顺序从缓存器中读取，如缓存器按时间先后顺序存储的HARQ进程分别为{H1，H2，H3，H4，H5，H6，…}，那么当指示的HARQ进程为H1，且调度的物理共享信道数量为4时，则重传的物理共享信道对应的HARQ进程依次为{H1，H2，H3，H4}。Optionally, if retransmission is indicated, the HARQ process of the first retransmission physical shared channel is indicated in the DCI at the same time, and the HARQ processes of other physical shared channels are sequentially read from the buffer in chronological order, such as the buffer by time The HARQ processes stored in sequence are {H1, H2, H3, H4, H5, H6, ...}, then when the indicated HARQ process is H1 and the number of scheduled physical shared channels is 4, the retransmitted physical shared channels The HARQ processes corresponding to the channels are {H1, H2, H3, H4} in sequence.

如图7所示，假设共有32个HARQ进程，编号为0～31。在第一次调度(第一个PDCCH)的8个PDSCH(每个PDSCH对应一个时隙)分别配置HARQ进程0～7，其中第7个时隙即编号为6的HARQ进程对应的PDSCH传输失败，第二次调度的8个PDSCH分别配置HARQ进程8～15，其中编号为11和13的HARQ进程对应的PDSCH传输失败，第三次调度的8个PDSCH分别配置HARQ进程16～23，其中编号为17的HARQ进程对应的PDSCH传输失败，第四次调度的8个PDSCH分别配置HARQ进程24～31，其中编号为31的HARQ进程对应的PDSCH传输失败。As shown in FIG. 7 , it is assumed that there are 32 HARQ processes numbered 0-31. Configure HARQ processes 0 to 7 in the 8 PDSCHs (each PDSCH corresponds to a time slot) of the first scheduling (the first PDCCH), and the seventh time slot, that is, the PDSCH corresponding to the HARQ process numbered 6, fails to transmit , the 8 PDSCHs scheduled for the second time are respectively configured with HARQ processes 8-15, among which the PDSCH transmissions corresponding to the HARQ processes numbered 11 and 13 fail to be transmitted, and the 8 PDSCHs scheduled for the third time are respectively configured with HARQ processes 16-23, where the numbered The PDSCH transmission corresponding to the 17th HARQ process fails, and the 8 PDSCHs scheduled for the fourth time are respectively configured with HARQ processes 24 to 31, and the PDSCH transmission corresponding to the HARQ process numbered 31 fails.

终端设备102会将传输成功或传输失败的信息以肯定应答(acknowledgement，ACK)或否定应答(negative acknowledgement，NACK)的形式反馈给网络设备101，网络设备101根据终端设备102的反馈信息，即可确认出传输失败的PDSCH对应的HARQ进程，并按产生错误的时间顺序存储在缓存器中，即缓存器中按时间先后顺序存储的HARQ进程依次为{6，11，13，17，31}。在下一次调度中，若调度的PDSCH均为重传PDSCH，则重传的PDSCH对应的HARQ进程依次按存入缓存器的先后顺序取，如重传的PDSCH数为4，在DCI中指示HARQ进程为6，则除了首个PDSCH的其他PDSCH的HARQ进程分别为11，13，17，然后网络设备依次选择缓存器中HARQ进程6和位于6之后的三个HARQ进程对应的PDSCH重传，即HARQ进程分别为6，11，13，17对应的PDSCH重传。Theterminal device 102 will feed back information about the success or failure of the transmission to thenetwork device 101 in the form of an acknowledgment (ACK) or a negative acknowledgment (NACK), and thenetwork device 101 can, according to the feedback information from theterminal device 102, Confirm the HARQ process corresponding to the PDSCH that failed to transmit, and store it in the buffer according to the time sequence in which the error occurred, that is, the HARQ processes stored in the buffer in chronological order are {6, 11, 13, 17, 31}. In the next scheduling, if the scheduled PDSCHs are all retransmitted PDSCHs, the HARQ processes corresponding to the retransmitted PDSCHs are taken in the order in which they are stored in the buffer. For example, the number of retransmitted PDSCHs is 4, and the HARQ process is indicated in the DCI is 6, the HARQ processes of other PDSCHs except the first PDSCH are 11, 13, and 17 respectively, and then the network device sequentially selects the PDSCH retransmission corresponding to theHARQ process 6 in the buffer and the three HARQ processes after 6, that is, HARQ The processes are the PDSCH retransmission corresponding to 6, 11, 13, and 17 respectively.

在下一次调度中，若调度的PDSCH均为初传，则可以指示第一个PDSCH的HARQ进程为0，或32mod 32，A mod B表示A除以B的余数，如10mod 32＝10，40mod 32＝8，则其他的PDSCH的HARQ进程依次加一。由于网络设备101还未收到终端设备102反馈的重传的HARQ进程{6，11，13，17}对应的PDSCH正确传输的信息，因此在依次加一的过程中，需要跳过缓存器中的HARQ进程，如跳过HARQ进程{6，11，13，17，31}，因此此时调度的初传PDSCH的HARQ进程分别为{0，1，2，3，4，5，7，8}。In the next scheduling, if the scheduled PDSCHs are all initial transmissions, you can indicate that the HARQ process of the first PDSCH is 0, or 32mod 32, A mod B means the remainder of dividing A by B, such as 10mod 32 = 10, 40mod 32 =8, then the HARQ processes of other PDSCHs are incremented by one. Since thenetwork device 101 has not received the correct transmission information of the PDSCH corresponding to the retransmitted HARQ process {6, 11, 13, 17} fed back by theterminal device 102, it is necessary to skip HARQ process, such as skipping the HARQ process {6, 11, 13, 17, 31}, so the HARQ process of the initial transmission PDSCH scheduled at this time is {0, 1, 2, 3, 4, 5, 7, 8 }.

因此，当单个DCI调度的物理共享信道的数量为N(N为大于1的整数)，且每个物理共享信道只有一个码字时，相比目前NR协议，可以减少指示所有PDSCH是初传还是重传的域在DCI中的负载，共N-1个比特，进一步地，当结合情形1中的方案，即同时隐式或间接指示RV信息时，可以省略或减少DCI中指示各PDSCH的RV的N个比特，即集合情形1和情形2，总共减少2N-1个比特。Therefore, when the number of physical shared channels scheduled by a single DCI is N (N is an integer greater than 1), and each physical shared channel has only one codeword, compared with the current NR protocol, it can be reduced to indicate whether all PDSCHs are initially transmitted or transmitted. The load of the retransmitted field in the DCI is N-1 bits in total. Furthermore, when combined with the solution inCase 1, that is, when the RV information is implicitly or indirectly indicated at the same time, the RV indicated in each PDSCH in the DCI can be omitted or reduced The N bits of , that is,aggregate case 1 andcase 2, reduce 2N-1 bits in total.

根据本申请的技术方案，当单个DCI调度的多个物理共享信道均用于初传或者重传数据时，增加一个比特可以联合指示该DCI调度的全部物理共享信道均用于初传或者重传数据，替代每个物理共享信道对应的NDI域，显著减少了多个物理共享信道的NDI指示比特数，有助于减少DCI的负载，提升PDCCH的覆盖。According to the technical solution of this application, when multiple physical shared channels scheduled by a single DCI are used for initial transmission or retransmission of data, adding one bit can jointly indicate that all physical shared channels scheduled by the DCI are used for initial transmission or retransmission The data replaces the NDI field corresponding to each physical shared channel, significantly reducing the number of NDI indication bits of multiple physical shared channels, helping to reduce the DCI load and improve the coverage of the PDCCH.

情形3：Case 3:

在该情形下，第一信息用于联合指示多个物理共享信道的NDI信息。此时，多个物理共享信道包括用于初传数据的信道和用于重传数据的信道。In this case, the first information is used to jointly indicate NDI information of multiple physical shared channels. At this time, the multiple physical shared channels include a channel for initial data transmission and a channel for retransmission data.

具体地，此时DCI还包括第三信息，即需要K_b个比特指示一次调度(单DCI)中重传的物理共享信道的数量。且重传的物理共享信道位于单DCI调度的多物理共享信道中固定的位置，如前K_ReT(0<＝K_ReT<＝2^K_b-1，K_b为DCI中指示重传的PDSCH数量的域负载)个物理共享信道为重传的物理共享信道。还可以是后K_ReT个物理共享信道为重传的物理共享信道。K_ReT的值由K_b个比特的指示值确定，如以K_b＝2为例，‘00’表示重传的PDSCH数量为0，‘01’表示重传的PDSCH数量为1，‘10’表示重传的PDSCH数量为2，‘11’表示重传的PDSCH数量为3。Specifically, at this time, the DCI also includes third information, that is, K_b bits are required to indicate the number of retransmitted physical shared channels in one scheduling (single DCI). And the retransmitted physical shared channel is located at a fixed position in the multi-physical shared channel scheduled by single DCI, such as the previous K_ReT (0<=K_ReT <=2^K_b -1, K_b is the PDSCH indicating retransmission in the DCI The domain load of the number) physical shared channel is the physical shared channel for retransmission. It may also be that the last K_ReT physical shared channels are physical shared channels for retransmission. The value of K_ReT is determined by the indicator value of K_b bits. For example, taking K_b = 2 as an example, '00' indicates that the number of retransmitted PDSCHs is 0, '01' indicates that the number of retransmitted PDSCHs is 1, and '10' Indicates that the number of retransmitted PDSCHs is 2, and '11' indicates that the number of retransmitted PDSCHs is 3.

例如，DCI还可以包括第四信息，第四信息用于指示用于重传数据的物理共享信道中的首个物理共享信道的HARQ进程。其他用于重传数据的物理共享信道的HARQ进程则依次从缓存器中按时间先后顺序选择，此部分请参照情形2中的描述，在此不再赘述。其他用于初传数据物理共享信道的HARQ进程确定方法如下：For example, the DCI may further include fourth information, and the fourth information is used to indicate the HARQ process of the first physical shared channel among the physical shared channels used for retransmitting data. The other HARQ processes of the physical shared channel used for retransmitting data are sequentially selected from the buffer in chronological order. For this part, please refer to the description inscenario 2, and details will not be repeated here. Other HARQ process determination methods for the initial data transmission physical shared channel are as follows:

a)确定第一个用于初传数据的物理共享信道的HARQ进程：第一个用于初传数据的物理共享信道的HARQ进程为指示的第一个重传HARQ进程后可用的第一个进程，可用的进程指不属于重传缓存器中的进程，且不属于已被调度的还未收到反馈信息的物理共享信道对应的进程。具体地，参照图5中的描述，用于初传数据的首个物理共享信道的HARQ进程为以DCI中指示的第一个物理共享信道的HARQ进程为起点(不包括该HARQ进程)，按照顺时针顺序，且不在或不属于重传HARQ进程集合中的第一个HARQ进程。a) Determine the first HARQ process of the physical shared channel used for initial data transmission: the first HARQ process of the physical shared channel used for initial data transmission is the first available after the indicated first retransmission HARQ process Process, an available process refers to a process that does not belong to the process in the retransmission buffer, and does not belong to the process corresponding to the scheduled physical shared channel that has not received feedback information. Specifically, referring to the description in FIG. 5, the HARQ process of the first physical shared channel used for initial data transmission starts from the HARQ process of the first physical shared channel indicated in the DCI (excluding the HARQ process), according to In clockwise order, and not in or not belonging to the first HARQ process in the retransmission HARQ process set.

b)其他用于初传数据的物理共享信道的HARQ进程在第一个用于初传数据的物理共享信道的HARQ进程基础上，依次加一，且跳过缓存器中存储的HARQ进程，进一步地，由于HARQ进程不是无限制增加的，目前NR协议中，HARQ进程的总数量为32、16或者64，即HARQ进程的取值范围为0～32、0～15或者0～63，因此当传输的PDSCH数量超过32(或者16或者64)后，会重新从0开始计数，并依据此规律进行循环。示例性的，假设重传对应的HARQ进程集合为空集，调度的第i+1个物理共享信道的HARQ进程可以是mod(A+i，M)，其中，A为指示的HARQ进程，M为HARQ进程的总数量，如32、16或者64。b) The HARQ process of other physical shared channels used for initial data transmission is based on the HARQ process of the first physical shared channel used for initial data transmission, plus one in turn, and the HARQ process stored in the buffer is skipped, further Specifically, since the HARQ process is not unlimitedly increased, in the current NR protocol, the total number of HARQ processes is 32, 16 or 64, that is, the value range of the HARQ process is 0-32, 0-15 or 0-63, so when After the number of transmitted PDSCHs exceeds 32 (or 16 or 64), it will restart counting from 0, and cycle according to this rule. Exemplarily, assuming that the set of HARQ processes corresponding to the retransmission is an empty set, the HARQ process of the scheduled i+1th physical shared channel may be mod(A+i, M), where A is the indicated HARQ process, and M is the total number of HARQ processes, such as 32, 16 or 64.

如图8所示，假设共有32个HARQ进程，编号为0～31，前四次调度中依次有HARQ进程为{6，10，13，17，31}的PDSCH传输失败。则终端设备102上报后，网络设备101端的重传数据缓存器中可以存储{6，10，13，17，31}。当下一次传输时，总共调度了8个时隙，其中用于指示用于重传数据的PDSCH数量的比特即K_b为2，指示值为‘11’，即有3个PDSCH的数据为重传数据，剩下的5个PDSCH的数据均为初传数据。假设指示的第一个用于传输重传数据的PDSCH的HARQ进程为6，其他用于传输重传数据的PDSCH的HARQ进程依次从重传数据缓存器中按时间先后顺序取出，即第二个和第三个用于重传数据的PDSCH的HARQ进程依次为6之后的10和13。根据前文所述的方法，第一个用于初传数据的PDSCH的HARQ进程为6之后第一个可用的进程，可知，第一个用于初传数据的PDSCH的HARQ进程为7，其他用于初传数据的PDSCH的HARQ进程依次+1，且跳过缓存器中的HARQ进程，即其他用于初传数据的PDSCH的HARQ进程为8，9，11，12(跳过HARQ进程10)。As shown in FIG. 8 , assuming that there are 32 HARQ processes in total, numbered 0-31, in the first four schedulings, the PDSCH transmissions of the HARQ processes {6, 10, 13, 17, 31} failed sequentially. Then, after theterminal device 102 reports, {6, 10, 13, 17, 31} may be stored in the retransmission data buffer at thenetwork device 101 side. When the next transmission, a total of 8 time slots are scheduled, where the bit used to indicate the number of PDSCHs used for retransmission data, that is, K_b is 2, and the indication value is '11', that is, there are 3 PDSCH data for retransmission data, and the data of the remaining 5 PDSCHs are initial transmission data. Assume that the indicated HARQ process of the first PDSCH used to transmit retransmitted data is 6, and the HARQ processes of other PDSCHs used to transmit retransmitted data are sequentially taken out from the retransmitted data buffer in chronological order, that is, the second and The third HARQ process of the PDSCH used for retransmitting data is 10 and 13 after 6 in sequence. According to the method described above, the HARQ process of the first PDSCH used for the initial data transmission is the first available process after 6. It can be seen that the HARQ process of the first PDSCH used for the initial data transmission is 7, and the other uses The HARQ process of the PDSCH for the initial data transmission is sequentially +1, and the HARQ process in the buffer is skipped, that is, the HARQ processes of other PDSCHs for the initial data transmission are 8, 9, 11, 12 (skip the HARQ process 10) .

需要说明的是，若HARQ进程24～31对应的PDSCH的ACK和NACK信息未及时在PUCCH资源上反馈，则在确定用于初传数据的PDSCH的HARQ进程时，HARQ进程24～31也属于不可用进程。It should be noted that if the ACK and NACK information of the PDSCH corresponding to the HARQ processes 24-31 are not fed back on the PUCCH resource in time, when determining the HARQ process of the PDSCH used for the initial data transmission, the HARQ processes 24-31 are also unavailable. Use the process.

因此，当单个DCI调度的物理共享信道的数量为N(N为大于1的整数)，且每个物理共享信道只有一个码字时，相比目前NR协议，DCI负载可以减少N-K_b个用于指示所有PDSCH的数据是初传还是重传的比特，进一步地，当结合情形1中的方案，即同时隐式或间接指示各PDSCH的RV信息时，DCI负载还可以减少或省略指示RV的N个比特，即总共减少2N-K_b个比特。Therefore, when the number of physical shared channels scheduled by a single DCI is N (N is an integer greater than 1), and each physical shared channel has only one codeword, compared with the current NR protocol, the DCI load can be reduced by NK_b for Indicates whether the data of all PDSCHs are initial transmission or retransmission bits. Furthermore, when combined with the solution inCase 1, that is, when the RV information of each PDSCH is implicitly or indirectly indicated at the same time, the DCI load can also reduce or omit the N indicating the RV. bits, that is, a total reduction of 2N-K_b bits.

情形4Situation 4

在该情形下，第一信息用于联合指示物理共享信道的多个码字的NDI信息和/或RV信息。In this case, the first information is used to jointly indicate NDI information and/or RV information of multiple codewords of the physical shared channel.

其具体指示方法与上文相同，即在DCI中通过一个域，同时指示一个物理共享信道的多个码字是用于初传还是重传数据，此时仅需要一个比特，替代目前NR协议一个物理共享信道的每个码字均有一个比特指示该信道用于初传或重传数据。The specific indication method is the same as above, that is, through a field in the DCI, at the same time indicate whether multiple codewords of a physical shared channel are used for initial transmission or retransmission data. At this time, only one bit is needed to replace the current NR protocol. Each codeword of the physical shared channel has a bit indicating that the channel is used for initial transmission or retransmission of data.

还包括，在DCI中通过一个域，同时指示一个物理共享信道的多个码字的RV，即多个码字的RV相同，此时仅需要2个或1个比特(2个对应单PDSCH，1一个对应多PDSCH)，替代目前NR协议中一个物理共享信道的每个码字均有一个比特指示该信道传输数据过程中的RV版本。It also includes, through a field in the DCI, indicating the RV of multiple codewords of a physical shared channel at the same time, that is, the RV of multiple codewords is the same, and only 2 or 1 bits are required at this time (2 corresponds to a single PDSCH, 1 corresponding to multiple PDSCHs), replacing each codeword of a physical shared channel in the current NR protocol has a bit indicating the RV version in the process of transmitting data on this channel.

当单个DCI调度的物理共享信道的数量为N(N正整数)，且每个物理共享信道为双码字，每个物理信道的双码字的NDI均相同，用一个比特同时指示双码字的NDI，每个物理信道的双码字的RV均相同，用一个或2个比特同时指示双码字的RV时，相比目前NR协议，N>1时可以减少2N个比特(每个PDSCH可以减少1个指示第二个码字的NDI的比特，1个指示第二个码字的RV的比特)，N＝1时，可以减少3个比特(可以减少1个指示第二个码字的NDI的比特，2个指示第二个码字的RV的比特)。When the number of physical shared channels scheduled by a single DCI is N (N positive integer), and each physical shared channel is a double codeword, the NDI of the double codewords of each physical channel is the same, and one bit is used to indicate the double codeword at the same time The RV of the double codeword of each physical channel is the same, and when one or two bits are used to indicate the RV of the double codeword at the same time, compared with the current NR protocol, when N>1, 2N bits can be reduced (each PDSCH Can reduce 1 bit indicating the NDI of the second codeword, 1 bit indicating the RV of the second codeword), when N=1, can reduce 3 bits (can reduce 1 indicating the second codeword bits of the NDI, 2 bits indicating the RV of the second codeword).

进一步的，还可以结合情形1和/或情形2，进一步减少DCI负载。Further, the DCI load may be further reduced in combination withCase 1 and/orCase 2.

进一步地，在该情形下，本申请还可以采用多码字的MCS值采取差分指示的方式，减少DCI的负载。Further, in this case, the present application may also adopt a manner of differential indication of MCS values of multiple codewords to reduce the load of the DCI.

例如，第一个码字的MCS按目前NR协议中的方法指示(5个比特)，如MCS指示(MCS_idx)，第二个码字的MCS指示一个差分值，如△MCS，则第二个码字的MCS为MCS_idx-△MCS。For example, the MCS of the first codeword is indicated according to the method in the current NR protocol (5 bits), such as the MCS indication (MCS_idx), and the MCS of the second codeword indicates a differential value, such as △MCS, then the second The MCS of the code word is MCS_idx-△MCS.

可选地，本申请实施例可以对△MCS采取均匀调整步进的表示方式。具体地，例如，△MCS＝A*ii，ii＝1，2，…，I_max，A即为差分MCS调整步进，其取值可以大于1，如A＝2，I_max的取值可以固定，如I_max＝8，因为两个码字间的MCS差值超过一定阈值后，两个码字独立的MCS对系统性能提升有限，为了降低复杂度，可以不调度质量较差的层，即将调度层控制为调度单码字所需要的层数。如现有NR协议中，当层数大于4时，才调度双码字，若调度层数大于4时，层间信道质量差较大，此时双码字所在层的信道质量差较大，使得双码字的MCS差值超过阈值，则其相比于仅调度4层传输单码字，性能提升非常有限，因此从降低复杂度的角度，可以仅调度4层传输单码字。即双码字的MCS差值超过阈值后的应用场景有限，所以可以限制两个码字上MCS差值取值范围，通过避免配置出不合理的场景，进一步降低DCI中MCS的负载。Optionally, in this embodiment of the present application, a uniform adjustment step may be used to represent ΔMCS. Specifically, for example, △MCS=A*ii, ii=1, 2, ..., I_max, A is the differential MCS adjustment step, and its value can be greater than 1, such as A=2, the value of I_max can be fixed, For example, I_max=8, because when the MCS difference between two codewords exceeds a certain threshold, the independent MCS of two codewords can only improve the system performance. Controls the number of layers required to schedule a single codeword. For example, in the existing NR protocol, when the number of layers is greater than 4, the dual codewords are scheduled. If the number of scheduling layers is greater than 4, the channel quality difference between layers is relatively large. At this time, the channel quality difference of the layer where the dual codewords are located is relatively large. If the MCS difference of the double codewords exceeds the threshold, compared with only scheduling 4 layers for single codeword transmission, the performance improvement is very limited. Therefore, from the perspective of reducing complexity, only 4 layers for single codeword transmission can be scheduled. That is, the application scenarios after the MCS difference of the double codeword exceeds the threshold are limited, so the range of the MCS difference between the two codewords can be limited, and the load of the MCS in DCI can be further reduced by avoiding unreasonable configuration scenarios.

当单DCI调度的每个物理共享信道有双码字时，相比目前NR协议(以MCS指示需要5个比特为例)，I_max＝8时DCI负载可以减少2个比特(MCS域)，因为此时，第二个MCS仅需要3个比特指示，I_max＝4时DCI负载则可以减少3个比特(MCS域)，第二个MCS仅需要2个比特指示。进一步的，还可以与情形1和/或情形2中的方案相结合，即同时联合指示一个PDSCH的NDI和RV信息，或联合指示多个PDSCH的NDI信息，可以进一步的减少DCI的负载。When each physical shared channel scheduled by a single DCI has double codewords, compared to the current NR protocol (taking 5 bits for the MCS indication as an example), the DCI load can be reduced by 2 bits (MCS domain) when I_max=8, because At this time, the second MCS only needs 3-bit indication, and when I_max=4, the DCI load can be reduced by 3 bits (MCS field), and the second MCS only needs 2-bit indication. Furthermore, it can also be combined with the solution incase 1 and/orcase 2, that is, jointly indicate the NDI and RV information of one PDSCH at the same time, or jointly indicate the NDI information of multiple PDSCHs, which can further reduce the DCI load.

可选地，还可以对△MCS采取非均匀调整步进的表示方式。具体地，△MCS＝{MCS_△1，MCS_△2，…，MCS_{△I_max}}，其中MCS_△i-MCS_△(i-1)的值随着i的增加而增加，即在同一个MCS_idx下，基于△MCS确定的第二个码字的MCS对应的谱效越低时，两个连续的△MCS的差值越大。其有益效果请参照上述描述，在此不再赘述。Optionally, non-uniform adjustment steps can also be used for △MCS. Specifically, △MCS={MCS_△1 , MCS_△2 , ..., MCS_{△I_max} }, where the value of MCS_△i - MCS_△(i-1) increases with the increase of i, that is, under the same MCS_idx , the lower the spectral efficiency corresponding to the MCS of the second codeword determined based on ΔMCS, the greater the difference between two consecutive ΔMCS. For its beneficial effects, please refer to the above description, which will not be repeated here.

应理解，作为示例而非限定，上述对△MCS采取均匀量化以及非均匀量化只是本申请列举的一些表示方式。在实际应用中，或者随着技术的发展，△MCS还可以由其他表示方式，本申请不对其进行限定。例如，考虑到传输两个码字时第一个码字映射的层所对应的信道质量较好，其MCS取值会较高，比如大于10或者大于指定值，利用该特性，可以进一步降低第一个码字的MCS的负载，如限制双码字时第一个码字的MCS取值范围为A～28，假如A取值>＝13，则第一个码字的MCS的负载可以降低为4比特。It should be understood that, as an example rather than a limitation, the uniform quantization and non-uniform quantization for ΔMCS mentioned above are just some representations listed in this application. In practical applications, or with the development of technology, ΔMCS can also be expressed in other ways, which are not limited in this application. For example, considering that the channel quality corresponding to the layer mapped by the first codeword is better when transmitting two codewords, its MCS value will be higher, such as greater than 10 or greater than a specified value. Using this feature, the second layer can be further reduced. The MCS load of a codeword, for example, the MCS value range of the first codeword is A～28 when restricting double codewords, if the value of A>=13, then the MCS load of the first codeword can be reduced is 4 bits.

还应理解，上述差分指示还可以拓展到第二个码字的MCS值，即，第一个码字的MCS通过第二个码字的MCS和两个MCS之间的差分值确定。It should also be understood that the above differential indication may also be extended to the MCS value of the second codeword, that is, the MCS of the first codeword is determined by the MCS of the second codeword and the difference between the two MCSs.

根据本申请的技术方案，当DCI调度的多个物理共享信道包括多个码字时，在DCI中增加域用于指示物理共享信道多个码字的NDI信息，替代每个码字对应的NDI域，显著减少了多个码字的NDI指示比特数，进一步地，第二个码字可以通过第一个码字的MCS值和两个MCS值之间的差分值指示，可以进一步地减少DCI的负载，提升PDCCH的覆盖。According to the technical solution of this application, when the multiple physical shared channels scheduled by DCI include multiple codewords, a field is added in the DCI to indicate the NDI information of multiple codewords of the physical shared channel, replacing the NDI corresponding to each codeword field, which significantly reduces the number of NDI indication bits for multiple codewords. Further, the second codeword can be indicated by the MCS value of the first codeword and the difference between the two MCS values, which can further reduce the DCI load, and improve the coverage of the PDCCH.

需要说明的是，上述情形中，除情形2与情形3存在择一关系外，其他情形均可任意组合，以进一步的减少DCI的负载。例如上文已经列举的，情形2、情形3以及情形4可以与情形1相结合，在此基础上，本领域技术人员可以想到，情形2可以与情形4相结合，或者情形3可以与情形4相结合。又例如，尽管上文未示出，情形1、2(或3)和4也可以同时相结合，即第一信息用于联合指示单个DCI调度的多个物理共享信道的多个码字的NDI信息和/或RV信息。It should be noted that, in the above cases, except that there is an alternative relationship betweencase 2 andcase 3, other cases can be combined arbitrarily, so as to further reduce the load of the DCI. For example, as already listed above,Situation 2,Situation 3 and Situation 4 can be combined withSituation 1. On this basis, those skilled in the art can imagine thatSituation 2 can be combined with Situation 4, orSituation 3 can be combined with Situation 4. Combine. For another example, although not shown above,situations 1, 2 (or 3) and 4 can also be combined at the same time, that is, the first information is used to jointly indicate the NDI of multiple codewords of multiple physical shared channels scheduled by a single DCI information and/or RV information.
