- the foregoing case where the DCI schedules a PDSCH to be transmitted on one or more carriers can also be replaced with a case where a DCI indicating the release of SPS resources is transmitted on one or more carriers, and the foregoing manners are also applicable.
- Embodiment 1 (Method 1): Assume that both the first time unit and the second time unit are time slots, and that DCI can schedule a PDSCH to be transmitted on carrier 1 and carrier 2.

Whether the same affects whether the SLIV in TDRA is valid in different time slots, then the number of corresponding candidate downlink transmission opportunities in each time slot of the same carrier is the same; the terminal only needs to be based on the carrier.

- the TDRA form corresponding to each carrier can be the same or different, depending on the configuration and usage of the TDRA form. Any configuration method can be processed using the methods provided in the embodiments of this application; if the TDRA form Carrier 1 and carrier 2 are shared. For example, if a TDRA table is configured for the DCI of scheduling carrier 1 and carrier 2, and it is specified that this TDRA table is applicable to carrier 1 and carrier 2, or high-level signaling directly has a DCI Carrier 1 and carrier 2 scheduled at the same time are configured with a TDRA table to determine the time domain resources on these two carriers. Of course, there can be other configuration methods.
- Carrier 1 and carrier 2 need to be processed separately, so that the number of transmission opportunities in this candidate downlink transmission opportunity set is taken as Mc-max ; if the TDRA table is independent of carrier 1 and carrier 2, for example, high-level information Let carrier 1 and carrier 2 be configured with a TDRA table, the combination of SLIV set and K0 contained in each TDRA table is not exactly the same, or a TDRA table is configured for DCI or for two carriers, each row in the table Contains a combination of two SLIVs, and each SLIV corresponds to a carrier, as shown in Table 1 below, that is, the TDRA indicator field in the DCI indicates an index.
- the SLIV and K0 can be the same or different for the two carriers. If they are the same, you can also reserve a common K0 column for carrier 1 and carrier 2 in Table 1), of course, there can be other configurations.

- Time slot np, p is the number of offset time slots
- the uplink time slot corresponds to the downlink time slot, and the number is the same; when the SCS of the uplink transmission and the downlink transmission are different, one uplink time slot may correspond to multiple
- an uplink time slot n-1 on carrier 1 corresponds to time slots 2n-2 and 2n-2 on carrier 2 2n-1
- the sum of the number of candidate downlink transmission opportunities corresponding to these two time slots can be taken as the candidate downlink transmission opportunities of the second time unit corresponding to time slot n-1 on carrier 2, and the sum of the number of downlink transmission opportunities on carrier 1.
- the candidate downlink transmission opportunities of the second time unit corresponding to time slot n-1 are compared, and the maximum value of carrier 1 and carrier 2 is taken as Mc -max ; in addition, under other feedback timing definitions, regardless of whether the SCS is the same or Different, there may also be other situations where the numbers of the downlink time slots corresponding to the same uplink on carrier 1 and carrier 2 are different, as long as the terminal and base station can uniquely determine the correspondence between the downlink time slots on carrier 1 and carrier 2. (That is, it is possible to know which time slot on carrier 1 and which time slot on carrier 2 are used to transmit a PDSCH at the same time, that is, these two time slots are on carrier 1 and carrier 2 and uplink time slot n-1 respectively.
- the above methods 1-2 and 1-3 can be used to determine the number of candidate downlink transmission opportunities in the corresponding carrier 1 and carrier 2 time slots, and the maximum value is taken as the uplink time.
- Method B To determine whether the SLIV is valid, regardless of whether the TDRA table corresponding to each carrier is the same, because of the time slot structure on different carriers (which symbols in a time slot are configured as downlink symbols and which symbols are configured as uplink symbols Symbols) are different, the time slot structure of different time slots on the same carrier can also be different. It is necessary to judge whether SLIV is valid for each time slot on each carrier, so as to obtain the effective SLIV based on the current time slot.
- the candidate downlink transmission opportunity corresponding to this time slot the number of candidate downlink transmission opportunities obtained in different carriers and different time slots of the same carrier may be different; the advantage of judging whether SLIV is effective is that it can guarantee the HARQ-ACK code On the basis of this stability, the redundancy in the HARQ-ACK codebook is reduced to a certain extent, that is, only the HARQ-ACK position is reserved for subsequent downlink transmission opportunities corresponding to the SLIV where downlink transmission may actually occur;
- the time slot corresponding to the uplink time slot n-1 on carrier 1 and carrier 2 is n-1
- the time slot corresponding to the uplink time slot n-2 is n- 2.
- the specific carrier is carrier 1 (it can be determined according to specific rules, or a specific carrier obtained in advance by signaling, etc., the specific method is not limited)
- the specific way to obtain the HARQ-ACK codebook Same as above method 1-2, no further details; among them, because the number of candidate downlink transmission opportunities contained in each time slot on carrier 1 is not less than the number of candidate downlink transmission opportunities contained in carrier 2 in the corresponding time slot Therefore, even if the base station sends a DCI to schedule a PDSCH to be transmitted only in a certain time
- Embodiment 2 (Method 2): When it is supported to schedule a PDSCH to be transmitted on carrier 1 and carrier 2 through a DCI, assuming that carrier 1 is a specific carrier, and other assumptions are the same as the above methods A and B, then carrier 1 can be adjusted according to the prior art.
- the number of candidate downlink transmission opportunities to obtain an 8-bit HARQ-ACK codebook can also be determined by determining the number of candidate downlink transmission opportunities contained in timeslots n-1 and n-2 of carrier 1 according to the prior art, and then This number is respectively used as the number of candidate downlink transmission opportunities corresponding to uplink time slots n-1 and n-2, and then an 8-bit HARQ-ACK codebook is obtained for the PDSCH scheduled by DCI to be simultaneously transmitted on carrier 1 and carrier 2.
- the HARQ-ACK mapping method for the PDSCH transmitted on a certain carrier is the same as method A, which will not be repeated here;
- time slots n-1 and n-2 corresponding to the uplink time slots n-1 and n-2 on carrier 1 respectively contain 3 and 4 candidate downlink transmissions.
- opportunity to obtain a 7-bit HARQ-ACK codebook it is determined that the time slots n-1 and n-2 corresponding to the uplink time slots n-1 and n-2 on carrier 1 respectively contain 3 and 4 candidate downlink transmissions.

- Candidate downlink transmission opportunities are mapped (that is, this PDSCH is transmitted in time slot n on carrier 2, and carrier 1 is a specific carrier, so a time slot needs to be determined on carrier 1, and this time slot is the same as time slot n on carrier 2.
- this time slot is a time slot that is scheduled at the same time as time slot n on carrier 2 when DCI schedules two carriers at the same time according to the scheduling timing design, such as a time slot that can be determined based on the same K0 value, Find a SLIV that is the same as the SLIV used by the PDSCH in the corresponding time slot of carrier 1, so as to obtain a candidate downlink transmission opportunity corresponding to this PDSCH in this time slot of carrier 1, and then according to the candidate downlink The transmission opportunity uses the position of this time slot of carrier 1 to obtain the mapping position of the HARQ-ACK of the PDSCH in the HARQ-ACK codebook of carrier 1.
- the DCI may contain scheduling indication information for carrier 1 and carrier 2, independently indicating carrier 1 and carrier 2.
- the scheduling information on carrier 2 can also be that only one set of indication fields are included in the DCI, and the scheduling information provided is for two carriers Sharing, that is, for example, the TDRA indicator field in the DCI indicates a SLIV and K0, then on each carrier, a time domain transmission position is determined according to this SLIV and K0, or it can be that part of the indicator field in the DCI is two pairs
- Each carrier is independently indicated, and part of the indication field is shared by two carriers.

相关申请的交叉引用
本申请要求在2020年05月28日提交中国专利局、申请号为202010467902.1、申请名称为“信息传输方法及装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
本申请涉及通信技术领域,尤其涉及信息传输方法及装置。
关于下行控制信息(Downlink Control Information,DCI)调度物理下行共享信道(Physical Downlink Shared CHannel,PDSCH),现有技术中仅支持一个DCI调度一个PDSCH在某一个载波上传输,因此PDSCH都是在每个载波上独立存在的,因此现有技术中半静态混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ)确认码本(codebook)是针对每个载波产生HARQ-ACK码本,然后将多个载波的码本级联在一起得到最终的HARQ-ACK码本进行传输的。其中,HARQ确认包括肯定确认(ACK)和否定确认(NACK),本文为了方便描述,统一采用HARQ-ACK来表示HARQ确认。
若一个DCI调度一个PDSCH在多个载波上传输时,仍然采用现有技术中针对每个载波独立产生HARQ-ACK码本再级联在一起的方式,将导致对多个被联合调度的载波预留冗余的HARQ-ACK反馈比特,从而降低HARQ-ACK的传输效率和性能。
因此,目前针对一个DCI调度一个PDSCH同时在多个载波上传输时,HARQ-ACK是针对每个PDSCH反馈的,并不是针对每个载波,此时如何进行HARQ-ACK反馈现有技术中还没有给出明确的方案。

为了增加调度的效率,节省DCI开销,新的无线(New Radio,NR)版本17(Rel-17)中可能需要考虑采用一个DCI调度多个载波的方式,其中一种实现方式为一个DCI调度一个PDSCH在多个载波上传输,即从数据传输上并不增加DCI调度的PDSCH数量,而是从资源映射上,将一个PDSCH承载的数据映射到多个载波上对应的物理资源集合中传输,从而实现一个DCI调度多个载波上同时进行传输。在这种方式下,现有技术中的半静态HARQ-ACK码本的产生方式不再适用,因此,本申请实施例提供的信息传输方法及装置,可以用于提供此种情况下的通过半静态HARQ-ACK码本方式传输HARQ-ACK的技术方案。
其中,方法和装置是基于同一申请构思的,由于方法和装置解决问题的 原理相似,因此装置和方法的实施可以相互参见,重复之处不再赘述。
本申请实施例提供的技术方案可以适用于多种***,尤其是5G***。例如适用的***可以是全球移动通讯(global system of mobile communication,GSM)***、码分多址(code division multiple access,CDMA)***、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)通用分组无线业务(general packet radio service,GPRS)***、长期演进(long term evolution,LTE)***、LTE频分双工(frequency division duplex,FDD)***、LTE时分双工(time division duplex,TDD)、通用移动***(universal mobile telecommunication system,UMTS)、全球互联微波接入(worldwide interoperability for microwave access,WiMAX)***、5G***以及5G NR***等。这多种***中均包括终端设备和网络设备。
本申请实施例涉及的终端设备,可以是指向用户提供语音和/或数据连通性的设备,具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。在不同的***中,终端设备的名称可能也不相同,例如在5G***中,终端设备可以称为用户设备(user equipment,UE)。无线终端设备可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网进行通信,无线终端设备可以是移动终端设备,如移动电话(或称为“蜂窝”电话)和具有移动终端设备的计算机,例如,可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,它们与无线接入网交换语言和/或数据。例如,个人通信业务(personal communication service,PCS)电话、无绳电话、会话发起协议(session initiated protocol,SIP)话机、无线本地环路(wireless local loop,WLL)站、个人数字助理(personal digital assistant,PDA)等设备。无线终端设备也可以称为***、订户单元(subscriber unit)、订户站(subscriber station),移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点(access point)、远程终端设备(remote terminal)、接入终端设备(access terminal)、用户终端设备(user terminal)、用户代理(user agent)、用户装置(user device),本申请实施例中并不限定。
本申请实施例涉及的网络设备,可以是基站,该基站可以包括多个小区。根据具体应用场合不同,基站又可以称为接入点,或者可以是指接入网中在空中接口上通过一个或多个扇区与无线终端设备通信的设备,或者其它名称。网络设备可用于将收到的空中帧与网际协议(internet protocol,IP)分组进行相互转换,作为无线终端设备与接入网的其余部分之间的路由器,其中接入网的其余部分可包括网际协议(IP)通信网络。网络设备还可协调对空中接口的属性管理。例如,本申请实施例涉及的网络设备可以是全球移动通信***(global system for mobile communications,GSM)或码分多址接入(code division multiple access,CDMA)中的网络设备(base transceiver station,BTS),也可以是带宽码分多址接入(wide-band code division multiple access,WCDMA)中的网络设备(NodeB),还可以是长期演进(long term evolution,LTE)***中的演进型网络设备(evolutional node B,eNB或e-NodeB)、5G网络架构(next generation system)中的5G基站,也可是家庭演进基站(home evolved node B,HeNB)、中继节点(relay node)、家庭基站(femto)、微微基站(pico)等,本申请实施例中并不限定。
下面结合说明书附图对本申请各个实施例进行详细描述。需要说明的是,本申请实施例的展示顺序仅代表实施例的先后顺序,并不代表实施例所提供的技术方案的优劣。
新的无线通信***(即5G NR,5Generation New RAT)中支持灵活的定时关系。对于物理下行共享信道(PDSCH,Physical Downlink Shared CHannel),承载其调度信息的物理下行控制信道(PDCCH,Physical Downlink Control CHannel)指示PDSCH与PDCCH之间的调度时序关系(Scheduling timing,即K0),以及PDSCH到其对应的HARQ-ACK之间的反馈时序关系(HARQ-ACK timing,即K1)。具体地,PDCCH所使用的下行控制信息(DCI,Downlink Control Information)格式中的时域资源分配(Time Domain Resource Assignment,TDRA)指示域,指示PDSCH所在时隙与PDCCH(也可以说DCI,因为DCI是PDCCH的具体传输格式,两者从描述调度和反馈关系上认为等 价)所在时隙的时隙偏移K0。DCI格式中的PDSCH到HARQ-ACK反馈定时(PDSCH-to-HARQ_feedback timing)指示域指示PDSCH结束到HARQ-ACK开始之间的时隙个数K1,即时隙n中传输的PDSCH在时隙n+K1中进行HARQ-ACK传输。
5G NR***中支持半静态(semi-static)和动态(dynamic)两种HARQ-ACK码本(codebook)产生方式。所谓HARQ-ACK codebook即针对在同一个时域位置或上行信道上进行HARQ-ACK反馈的下行传输(包括PDSCH和SPS PDSCH release)产生的HARQ-ACK反馈序列。
semi-static codebook可以根据K1集合中的HARQ-ACK timing值确定每个载波c上(具体的是这个载波上当前激活的部分带宽(Bandwidth partial,BWP)上)对应在一个时隙(slot)或子时隙(sub-slot)n中进行HARQ-ACK反馈的下行传输的位置集合M
c,然后根据M
c即可以确定时隙或子时隙n中传输的HARQ-ACK codebook。
本申请实施例提供的技术方案中,当一个DCI支持调度一个PDSCH在多个载波上传输时(是从DCI的功能上可以允许调度一个PDSCH在多个载波上传输,对于这种DCI,一种实现方式是,规定这样的DCI在调度PDSCH传输时,总是调度一个PDSCH在多个载波上传输,另一种实现方式是,不限制DCI实际调度的PDSCH在几个载波上传输,例如DCI的某一次调度,可以是调度一个PDSCH在一个载波上传输,DCI的另一调度,也可以是调度一个PDSCH在多个载波上传输),对可以由所述DCI调度的多个载波,以所述多个载波为一组,确定一个HARQ-ACK码本,即可以由所述DCI调度的多个载波为一组,统一产生一个HARQ-ACK码本。具体地,例如:
方式1:当在第一时间单元n中传输HARQ-ACK码本时(即DCI调度的下行传输需要在第一个时间单元n中进行HARQ-ACK传输时,需要产生第一时间单元n中传输的HARQ-ACK码本),根据反馈定时K1集合中的每一个值K1i确定一个第一时间单元n-K1
i,确定一个第一时间单元n-K1
i对应的候选的下行传输机会个数(或者也可以称为HARQ-ACK位置个数,一个位置对 应一个下行传输的HARQ-ACK,一个HARQ-ACK位置可以对应1或多比特HARQ-ACK,具体取决于一个下行传输对应的HARQ-ACK比特数)M
c-max;
每一个对应在第一时间单元n中传输HARQ-ACK的第一时间单元n-K1
i对应的M
c-max个候选的下行传输机会,按照对应的K1值的固定顺序级联在一起,构成所述多个载波对应的候选的下行传输机会集合,在第一时间单元n中传输的HARQ-ACK码本中包含与所述候选的下行传输机会集合对应的HARQ-ACK比特数;
所述HARQ-ACK码本中的HARQ-ACK按照接收到的下行传输与所述候选的下行传输机会集合中的下行传输机会的对应关系,映射到所述HARQ-ACK码本中的对应位置。
其中,M
c-max例如可以采用如下方式获得:
方式1-1:M
c-max为所述多个载波中的每个载波上在所述第一时间单元n中进行HARQ-ACK反馈的每个第二时间单元中包含的候选的下行传输机会的最大值;
方式1-1适用于任何情况,包括调度时序(timing)设计上对多个载波是独立的调度timing,即不同的K0值,或者是共同(common)的调度timing,即相同的K0值,根据预定规则,可以基于相同的K0值分别得到每个载波上被调度的具体时间单元;
方式1-2:对于每一个第一时间单元n-K1
i,M
c-max为所述多个载波中的每个载波上对应第一时间单元n-K1
i的第二时间单元中包含的候选的下行传输机会的最大值;
如果在某一个载波上存在多个第二时间单元与所述第一时间单元n-K1
i对应,则这个载波上对应第一时间单元n-K1
i的第二时间单元中包含的候选的下行传输机会为多个第二时间单元中包含的候选的下行传输机会的并集(具体就是多个第二时间单元分别对应的候选的下行传输机会集合按照第二时间单元的前后顺序级联在一起得到的);
方式1-2可以适用于common的调度timing,即在已知第一时间单元n-K1
i 时,根据预定的调度timing规则,可以得到与这个第一时间单元n-K1
i对应的在每个载波上的第二时间单元,即可以根据调度和反馈timing的设计,推断出以第一时间单元n-K1
i为参考的每个被调度的载波上的第二时间单元,即每个载波上的与第一时间单元n-K1
i对应的第二时间单元是固定的,并不是可变的;当然,也不排除方式1-2应用于其他场景;
例如,假设一个DCI调度的多个载波的子载波间隔(Sub-CarrierSpace,SCS)相同,且K0相同,则一个DCI调度在多个载波上根据K0值确定的同一个时隙中传输PDSCH,并且反馈timing定义以与PDSCH所在时隙重叠的最后一个PUCCH时隙(即根据PUCCH传输的SCS确定时隙,即传输PUCCH的载波上的时隙)作为K1=0的参考时隙,从而根据K1值找到HARQ-ACK传输所在的时隙,那么按照这个反过程,当HARQ-ACK在时隙n传输时,可以根据一个K1值得到K1=0的参考时隙n-K1,进而得到与这个时隙重叠的被调度载波上的时隙,就可以知道被调度载波上是哪个时隙与参考时隙n-K1对应了,从而可以依据这些确定的时隙中对应的候选下行传输机会来确定M
c-max。
与方式1-1的区别在于,方式1-1是取了多个载波上所有根据K0和K1的各种组合可能在时隙n中进行HARQ-ACK反馈的时隙中的Mc的最大值,即假设上下行载波的SCS相同,K1={1,2},载波1和载波2上都可能存在时隙n-2和n-1需要在时隙n进行HARQ-ACK反馈,而载波1上的时隙n-2和n-1中可能分别对应的下行传输机会个数分别为3和2,载波2上的时隙n-2和n-1中可能分别对应的下行传输机会个数分别为5和4,那么按照方式1-1,确定的M
c-max=max(3,2,5,4)=5,即根据K1值确定的每个与时隙n(传输HARQ-ACK的时隙)对应的第一时间单元(即时隙n-1和n-2)都对应M
c-max=5个候选的下行传输机会,则多个载波对应的候选的下行传输机会集合中包含了5+5=10个候选的下行传输机会,按照方式1-2,根据K1=1得到参考时隙n-1,与n-1对应的载波1和载波2的时隙假设都为n-1,那么对于参考时隙n-1确定的M
c-max=max(2,4)=4,根据K1=2得到参考时隙n-2,与n-2对应的载波1和载波2的时隙假设都为n-2,那么对于参考时隙n-2确定的 M
c-max=max(3,5)=5,即根据K1值确定的每个与时隙n(传输HARQ-ACK的时隙)对应的第一时间单元(即时隙n-1和n-2)分别对应M
c-max=4和5个候选的下行传输机会,则多个载波对应的候选的下行传输机会集合中包含了4+5=9个候选的下行传输机会。
方式1-3:M
c-max为所述多个载波中的一个特定载波上对应第一时间单元n-K1
i的第二时间单元中包含的候选的下行传输机会;
在方式1-3下,因为根据其中一个载波来确定候选的下行传输机会,如果出现一个DCI仅调度一个PDSCH在一个载波上传输,且传输的载波并不是特定载波的话,可能会出现特定载波上的候选的下行传输机会并不能包含这个载波上的PDSCH传输对应的HARQ-ACK位置的情况,此时需要基站调度保证不出现一个DCI仅调度一个PDSCH在一个载波上传输时其HARQ-ACK与一个DCI调度一个PDSCH在多个载波上传输时进行复用,或者基站调度上保证在其他非特定载波的载波上调度的PDSCH传输都能对应到M
c-max中的一个候选的下行传输机会中。
如果在所述特定载波上存在多个第二时间单元与所述第一时间单元n-K1
i对应,则这个载波上对应第一时间单元n-K1
i的第二时间单元中包含的候选的下行传输机会为多个第二时间单元中包含的候选的下行传输机会的并集;
其中,一个下行传输机会对应X比特HARQ-ACK反馈,X取决于PDSCH的配置参数,例如单传输块(Transport Block,TB)、多TB还是码块组(Code Block Group,CBG)传输,如多TB时是否采用HARQ-ACK空间合并等;
其中,每个第二时间单元中包含的候选的下行传输机会是基于时域资源分配(Time Domain Resource Allocation,TDRA)表格中的所有起点和长度指示值(Start and Length Indicator Value,SLIV)确定的,或者是基于TDRA表格中不与配置的(具体的可以是高层信令配置的)上行符号冲突的SLIV确定的(即有效的SLIV);所述TDRA表格为所述多个载波共有的TDRA表格,或者为对所述DCI配置的TDRA表格,或者为所述多个载波中的每一个载波各自对应的TDRA表格(即不同载波的TDRA表格独立配置,并不一定相同);
例如,当采用方式1-1时,每个第二时间单元中包含的候选的下行传输机会是基于TDRA表格中的所有SLIV确定的,即不进行SLIV是否有效(是否与配置的上行符号冲突)的判断,不去除任何SLIV;当然,也可以选择进行有效性判断,可以分别对每个载波上的第二时间单元先判断TDRA表格中的SLIV是否有效,基于有效的SLIV确定候选的下行传输机会;当采用方式1-2时,可以分别对每个载波上的第二时间单元先判断TDRA表格中的SLIV是否有效,基于有效的SLIV确定候选的下行传输机会;当然,也可以选择不进行有效性判断,分别对每个载波上的第二时间单元根据TDRA表格中的所有SLIV确定候选的下行传输机会;当采用方式1-3时,可以对一个特定载波上的第二时间单元先判断TDRA表格中的SLIV是否有效,基于有效的SLIV确定候选的下行传输机会,当然也可以不进行有效性判断,直接对这个特定载波上的第二时间单元根据TDRA表格中的所有SLIV确定候选的下行传输机会;
例如,当进行SLIV是否有效的判断时:
如果采用共有的TDRA表格,则对所述多个载波中的每个载波,在第二时间单元中,判断TDRA表格中的一个SLIV是否包括这个载波上配置的上行符号(包括,则为冲突),当不包含时,确定这个SLIV有效,当包含时,确定这个SLIV无效;或者,只有在所述多个载波上的所述第二时间单元中,这个SLIV都包含上行符号时,确定这个SLIV无效,其他情况都认为有效(即当所述SLIV在所述多个载波上的至少一个载波上对应的第二时间单元中不包含上行符号,确定所述SLIV有效);
如果采用每个载波单独对应的TDRA表格,则对所述多个载波中的每个载波,在第二时间单元中,判断这个载波对应的TDRA表格中的一个SLIV是否包括这个载波上配置的上行符号(包括,则为冲突),当不包含时,确定这个SLIV有效;
如果采用为DCI配置的TDRA表格,当所述TDRA表格中包含至少一行SLIV是对应一个SLIV组,该SLIV组中的每一个SLIV对应所述多个载波中 的每一个载波时,则当所述SLIV中的每一个SLIV在对应的载波中的所述第二时间单元中都包含上行符号时,确定这个SLIV组无效,否则确定这个SLIV组有效(即当所述SLIV中的SLIV在对应的载波中的至少一个载波上的第二时间单元中不包含上行符号时,确定所述SLIV有效);
其中,上述方式中,如果当前载波配置了PDSCH重复传输M次,则需要基于与第一时间单元n-K1
i对应的第二时间单元,确定M个用于重复传输的第二时间单元(例如第二时间单元为时间单元m,则进一步确定时间单元m-1,m-2,…m-M+1,以这M个时间单元为重复传输的时间单元集合),当一个SLIV在所述M个用于重复传输的第二时间单元的至少一个时间单元中不包含上行符号,确定这个SLIV有效,否则确定这个SLIV无效(即当这个SLIV在所述M个用于重复传输的第二时间单元的每一个时间单元中都包含上行符号时,确定所述SLIV无效);
当所述多个载波中的一个载波上与所述第一时间单元n-K1
i对应的第二时间单元中包含的候选的下行传输机会M
c小于M
c-max时,确定该载波上的M
c个候选的下行传输机会对应于所述M
c-max个候选的下行传输机会中的前M
c个候选的下行传输机会,或后M
c个候选的下行传输机会(如果是等于,就是一一对应);
当DCI调度了一个PDSCH在多个载波上传输时,根据所述PDSCH传输在所述多个载波中的一个特定载波,确定所述PDSCH的HARQ-ACK在所述HARQ-ACK码本中的映射位置;具体的:
在所述一个特定载波上所述下行传输所在的第二时间单元对应的一个第一时间单元n-K1i(即这个载波上的第二时间单元根据反馈定时的定义,确定是参考第一时间单元n-K1
i进行反馈定时的,即以第一时间单元n-K1
i为K1=0对应的时间单元)所对应的M
c-max个候选的下行传输机会中,确定出一个与所述PDSCH对应的候选的下行传输机会,所述PDSCH的HARQ-AK映射到HARQ-ACK码本中与所述对应的候选的下行传输机会所对应的HARQ-ACK位置;
当DCI调度一个PDSCH在所述多个载波上的一个载波上传输时,根据所述PDSCH传输所在的载波,确定所述PDSCH的HARQ-ACK在所述HARQ-ACK码本中的映射位置;具体的:
在所述PDSCH传输所在的载波上所述下行传输所在的第二时间单元对应的一个第一时间单元n-K1i(即这个载波上的第二时间单元根据反馈定时的定义,确定是参考第一时间单元n-K1
i进行反馈定时的,即以第一时间单元n-K1
i为K1=0对应的时间单元)所对应的M
c-max个候选的下行传输机会中,确定出一个与所述PDSCH对应的下行传输机会,所述PDSCH的HARQ-ACK映射到HARQ-ACK码本中与所述对应的下行传输机会所对应的HARQ-ACK位置。
方式2:将所述多个载波中的一个特定载波对应的HARQ-ACK码本,作为所述多个载波对应的HARQ-ACK码本;或者,将所述多个载波中的一个特定载波对应的候选的下行传输机会,作为所述多个载波对应的候选的下行传输机会,基于所述候选的下行传输机会,产生所述多个载波对应的HARQ-ACK码本;其中,具体的对每个载波确定HARQ-ACK码本或者确定候选的下行传输机会的过程为现有技术,不再赘述。
在使用方式2时,需要针对特定的场景,否则可能会出现根据特定载波确定的HARQ-ACK不能包含在另一个非特定载波上调度传输的PDSCH的HARQ-ACK反馈位置;例如,满足如下条件至少一个条件(根据预先规定,可以是满足其中某一个条件,也可以是满足其中多个条件)时使用方式2:
多个载波上的TDRA表格相同;
多个载波上的时隙结构(即哪些时隙是上行,哪些时隙是下行,一个时隙中的哪些符号是上行,哪些符号是下行,不指定为上行或下行的时隙或符号为灵活flexible的)相同;
多个载波的SCS相同;
多个载波中除了特定载波之外的载波上的SLIV包含在特定载波的TDRA表格中;
DCI总是调度PDSCH在所述多个载波中包含特定载波在内的一个或多个载波上传输。当然,也可以对方式2的使用不限制必须满足上述条件,此时,通过基站调度避免出现根据特定载波确定的HARQ-ACK不能包含在另一个非特定载波上调度传输的PDSCH的HARQ-ACK反馈位置的情况,或者出现了这个情况时,认为被调度的PDSCH无HARQ-ACK反馈。
上述方式中,所述特定载波可以为所述多个载波中编号最小或最大的载波,所述多个载波中SCS最小或最大的载波(如果存在多个载波的SCS相同,则可以是任意一个载波或SCS相同的载波中的编号最小或最大的载波),或者为高层信令预先指示的载波,或者所述DCI调度所述多个载波时作为调度时序参考的载波(即一个DCI调度在多个载波上传输PDSCH时,每个载波上在哪个时隙传输PDSCH的调度时序,是以这个载波为参考得到的,即K0是以这个载波为参考得到的),或者所述DCI调度所述多个载波时作为HARQ-ACK反馈时序参考的载波,即一个DCI调度在多个载波上传输PDSCH时,PDSCH在哪个时隙或子时隙反馈HARQ-ACK的反馈时序,是以这个特定载波为参考得到的,即是根据这个特定载波上的PDSCH的结束位置,找到传输PUCCH载波上的一个时隙作为K1=0的参考点的。
可选地,一个DCI调度的在多个载波上传输的PDSCH,与一个DCI调度的在一个载波上传输的PDSCH,不在同一个PUCCH中传输HARQ-ACK;
可选地,所述第一时间单元可以包括:预先定义的A个符号构成的时间段、或子帧、或时隙、或子时隙等,其中,A为正整数;
可选地,所述第二时间单元可以包括:预先定义的B个符号构成的时间段、或子帧、或时隙、或子时隙等,其中,B为正整数;
可选地,所述第一时间单元和所述第二时间单元的定义可以相同或者不同,例如第一时间单元和第二时间单元都是时隙,或者第一时间单元为子时隙,第二时间单元为时隙;
可选地,当配置使用半静态HARQ-ACK码本时,采用上述方式之一确定所述多个载波的HARQ-ACK码本。
终端按照上述方式确定HARQ-ACK码本,并发送给基站;基站是按照上述方式确定HARQ-ACK码本是以所述多个载波为一组产生的,并进行HARQ-ACK码本接收,并且按照终端产生HARQ-ACK码本的逆过程解析出HARQ-ACK码本中对应在多个载波上传输的PDSCH的HARQ-ACK。
上述DCI调度一个PDSCH在一个或多个载波上传输的情况也可以替换为一个指示SPS资源释放的DCI在一个或多个载波上传输的情况,上述方式同样适用。
下面给出几个具体实施例的举例说明。
实施例1(方式1):假设第一时间单元和第二时间单元都为时隙,假设DCI可以调度一个PDSCH在载波1和载波2上传输,两个载波的SCS相同,假设K1集合={1,2},则:
方式A:不进行SLIV是否有效的判断,因为不考虑不同时隙中的上下行划分(即可能一个时隙中包含A1个上行符号,一个时隙中包含A2个上行符号,且上行符号的位置也可能不同)是否相同对TDRA中的SLIV在不同时隙中是否有效的影响,则同一个载波的每个时隙中对应的候选的下行传输机会的个数是相同的;终端只需要根据载波对应的TDRA表格中的SLIV按照现有技术中的SLIV分组方式得到每个载波上的一个时隙对应的候选的下行传输机会,从而得到M
c-max;假设载波1的每个时隙中根据对应的TDRA表格中的SLIV集合确定了4个候选的下行传输机会,载波2的每个时隙中根据对应的TDRA表格中的SLIV确定了3个候选的下行传输机会,则确定M
c-max=4;当在上行时隙n中传输HARQ-ACK码本时,根据K1集合中的每个值,可以分别确定与上行时隙n对应的上行时隙n-1和上行时隙n-2,由于上行和下行的SCS相同,假设每个载波的反馈时序的定义就是以与一个下行时隙中的下行传输重叠的最后一个上行时隙为K1=0的参考点,则在这个反馈时序定义下,可以认为所有与一个上行时隙在时间上重叠的下行时隙(假设载波之间的时隙编号没有偏差),或者按照
的方式可以得到对应的下行 时隙的编号(其中n
U即为上行时隙n,K
1,k即为K1集合中的一个值,n
D为
的非负整数,μ
DL为下行传输的SCS对应的编号,μ
UL为上行传输的SCS对应的编号),基于上述方式,可以得到,与上行时隙n-1对应的下行时隙(即传输PDSCH的时隙)在载波1和载波2上都为时隙n-1,与上行时隙n-2对应的下行时隙(即传输PDSCH的时隙)在载波1和载波2上都为时隙n-2,则上行时隙n中的HARQ-ACK码本是包含了载波1和载波2上的下行时隙n-1和时隙n-2所对应的候选下行传输机会的码本,即假设每个候选下行传输机会对应的HARQ-ACK比特为1(当然在其他实施例中,还是对应X比特,X是与下行传输的配置相关的,比如2个TB传输且不使用空间合并,可以是2比特,配置了4个CBG,可以是4比特等等),则上行时隙n中对应载波1和载波2的HARQ-ACK码本包含了8比特信息,其中前4比特对应时隙n-2对应的4个候选下行传输机会,后4比特对应时隙n-1对应的4个候选下行传输机会;如果在下行时隙n-1中存在一个被调度在载波1和载波2上传输的PDSCH,假设其SLIV对应的是其传输所在时隙中的候选的下行传输机会中第3个,即也就是对应了上行时隙n-1(与这个下行时隙n-1对应的上行时隙)对应的M
c-max=4个候选的下行传输机会中的第3个候选的下行传输机会,则该PDSCH的HARQ-ACK映射到上行时隙n-1对应的4比特HARQ-ACK中的第3比特位置(即8比特HARQ-ACK码本中的第7比特位置);如果在下行时隙n-2中存在一个被调度仅在载波2上传输的PDSCH,假设其SLIV对应的是载波2的时隙n-2中的候选的下行传输机会中的第1个(假设载波2上时隙n-2中的3个候选的下行传输机会对应上行时隙n-2对应的M
c-max=4个候选的下行传输机会中的前3个,则这个PDSCH对应的下行传输机会对应上行时隙n-2对应的M
c-max=4个候选的下行传输机会中的第1个候选的下行传输机会),则该PDSCH的HARQ-ACK映射到上行时隙n-2对应的4比特HARQ-ACK中的第1比特位置(即8比特HARQ-ACK码本中的第1比特位置);终端在上行时隙n中,在确定的PUCCH资源上发送8比特 HARQ-ACK,如图1所示;基站按照上述同样的方式,可以确定终端在上行时隙n中发送了8比特HARQ-ACK码本,在对应的资源上进行接收,并按照上述同样方式可以从8比特HARQ-ACK码本中获得被调度的PDSCH的HARQ-ACK;
其中,根据TDRA表格确定候选的下行传输机会的方式为现有技术,例如,对于仅支持在一个时隙中接收一个单播(unicast)PDSCH的终端,直接确定每个载波的每个时隙对应1个候选的下行传输机会,即M
c-max=1;对于支持在一个时隙中接收超过一个unicast PDSCH的终端,使用每个载波对应的TDRA表格中的所有SLIV按照现有技术中的SLIV分组方式进行SLIV的分组方式,得到多个SLIV组,每个SLIV组对应一个候选的下行传输机会,从而得到每个载波上的每个时隙中的候选的下行传输机会;
其中,在8比特HARQ-ACK码本中还可能存在对应其他PDSCH的HARQ-ACK,这些PDSCH的HARQ-ACK映射到8比特HARQ-ACK码本中的过程同上类似,不再赘述;8比特HARQ-ACK码本所对应的PDSCH可以都是被调度在多个载波上传输的,也可以包含部分调度在多个载波上传输,部分调度在一个载波上传输;
其中,每个载波对应的TDRA表格可以是相同的,也可以是不同的,具体取决于TDRA表格的配置和使用方式,任何配置方式都可以使用本申请实施例提供的方式进行处理;如果TDRA表格对载波1和载波2是共享的,例如,如果对调度载波1和载波2的DCI配置了一个TDRA表格,并且规定这个TDRA表格适用于载波1和载波2,或者高层信令直接对有一个DCI同时调度的载波1和载波2配置一个TDRA表格,用于这两个载波上的时域资源确定,当然还可以有其他配置方式,只要是最终结果是两个载波的TDRA相同的,则在上述方式A中,只需要根据这一个TDRA表格中的SLIV按照现有技术中的SLIV分组方式得到一个时隙对应的候选的下行传输机会集合即可,这对载波1和载波2是相同的,不需要分别对载波1和载波2进行处理,从而将这个候选的下行传输机会集合中的传输机会个数作为M
c-max即可;如果 TDRA表格对于载波1和载波2是独立的,例如高层信令为载波1和载波2分别配置了一个TDRA表格,每个TDRA表格中包含的SLIV集合和K0的组合不完全相同,或者对DCI或对两个载波配置了一个TDRA表格,表格中的每一行包含了两个SLIV的组合,每一个SLIV对应一个载波,如下面的表1所示,即DCI中的TDRA指示域指示一个索引,根据表格可以得到分别对应载波1和载波2的SLIV和K0(当然,K0可以是两个载波相同的,也可以是不同的,如果是相同的,表1中也可以对载波1和载波2保留一个公共的K0列即可),当然还可以有其他配置方式实现两个载波独立的TDRA表格配置,则因为两个载波的TDRA表格中包含的SLIV集合可能是不同的,需要针对两个TDRA表格分别确定每个载波对应的候选的下行传输机会集合,且得到的载波1和载波2上在一个时隙中的候选的下行传输机会的个数可能是不同的,此时取最大值作为M
c-max即可,而对于实际对应的候选下行传输机会的个数小于M
c-max的载波,可以规定是与M
c-max个下行传输机会中的前几个或者后几个对应的,从而可以将载波对应的候选下行传输机会个数小于M
c-max的载波上传输的PDSCH,根据其在这个载波上的下行传输机会与M
c-max个下行传输机会中的某一个机会的对应关系,确定其HARQ-ACK映射到HARQ-ACK码本中的位置。
其中,上述实施例中,因为上行传输和下行传输的SCS相同,且不同载波之间并不存在时隙偏移(即时隙编号上不对齐,比如载波1上的时隙n对应载波2上的时隙n-p,p是偏移的时隙个数),上行时隙与下行时隙一一对应,且编号相同;当上行传输和下行传输的SCS不同时,可能出现一个上行时隙对应多个下行时隙的情况,例如假设载波1的SCS为15kHz,载波2的SCS为30kHz时,按照上述同样假设,载波1上的一个上行时隙n-1对应载波2上的时隙2n-2和2n-1,则可以取这两个时隙各自对应的候选下行传输机会的个数之和作为载波2上与时隙n-1对应的第二时间单元的候选下行传输机会,与载波1上与时隙n-1对应的第二时间单元的候选下行传输机会进行比较,取载波1和载波2中的最大值作为M
c-max;此外,在其他的反馈时序定义下,不 论SCS相同或不同,也可能会出现载波1和载波2上与同一个上行对应的下行时隙的编号不同等其他情况,只要终端和基站能唯一确定载波1和载波2上的下行时隙之间的对应关系(即能够知道载波1上的哪个时隙与载波2上的哪个时隙是用来同时传输一个PDSCH的,即这两个时隙是分别在载波1和载波2上与上行时隙n-1或n-2对应的),就可以使用上述方式1-2和1-3确定对应的载波1和载波2上的时隙中的候选的下行传输机会的个数,从而取最大值作为上行时隙对应的下行传输机会个数,而方式1-1,因为M
c-max覆盖了所有载波上的所有时隙的可能的候选下行传输机会的情况,所以并不限制两个载波上的对应同一个上行时隙n-1或n-2的下行时隙之间是否有关联,比如DCI,如果是单独指示PDSCH在每个载波上的传输时隙(K0)以及反馈时隙(K1)时,也可以做到在一个PDSCH在载波1和载波2上的任意两个时隙中传输时,在时隙n中进行HARQ-ACK反馈,此时由于并不知道载波1和载波2上与一个上行时隙n-1对应的到底是哪两个时隙,则需要按照所有时隙中包含的候选下行传输机会的最大值进行一个上行时隙n-1和n-2对应的候选的下行传输机会的确定以及对应的HARQ-ACK反馈位置的预留。
表1:TDRA表格
方式B:进行SLIV是否有效的判断,则不管每个载波对应的TDRA表格是否相同,因为不同载波上的时隙结构(一个时隙中的哪些符号被配置为下行符号、哪些符号被配置为上行符号)不同,同一个载波上的不同时隙的时 隙结构也可以不同,需要对每个载波上的每个时隙分别进行SLIV是否有效的判断,从而基于当前时隙中的有效的SLIV得到这个时隙对应的候选下行传输机会,不同载波、同一个载波的不同时隙中得到的候选下行传输机会的个数可能是不同的;判断SLIV是否有效的好处,在于可以在保证HARQ-ACK码本稳定性的基础上,在一定程度上降低HARQ-ACK码本中的冗余,即仅对实际可能发生下行传输的SLIV对应的后续下行传输机会预留HARQ-ACK位置;
具体的:按照同上述方式A中的方式,可以得到载波1和载波2上与上行时隙n-1对应的时隙为n-1,与上行时隙n-2对应的时隙为n-2,分别在载波1和载波2上的时隙n-1和n-2中对TDRA表格中的每个SLIV确定是否有效(即这个SLIV是否包含上行符号,包含为无效,不包含为有效),根据有效的SLIV确定每个载波的每个时隙中包含的候选下行传输机会,即当所述终端在一个第二时间单元中仅支持接收一个单播PDSCH时,如果所述第二时间单元中至少包含一个有效SLIV,则确定所述第二时间单元包含1个候选的下行传输机会(否则,没有下行传输机会,即如果所述第二时间单元中不包含有效SLIV,则确定所述第二时间单元中不存在候选的下行传输机会),当所述终端在一个第二时间单元中支持接收超过一个单播PDSCH时,基于所述第二时间单元中确定的有效SLIV,确定所述第二时间单元中的候选的下行传输机会;假设载波1上时隙n-1中确定的候选下行传输机会为3个(即因为判断了SLIV有效性,相对于方式A,减少了1个候选的下行传输机会),载波1上时隙n-2中确定的候选下行传输机会为4个,载波2上时隙n-1中确定的候选下行传输机会为2个(即因为判断了SLIV有效性,相对于方式A,减少了1个候选的下行传输机会),载波2上时隙n-2中确定的候选下行传输机会为3个;
当采用方式1-1时,确定每一个上行时隙(即时隙n-1和n-2)对应的候选下行传输机会的个数都为M
c-max=max(3,4,2,3)=4,即假设每个候选下行传输机会对应的HARQ-ACK比特为1时,类似上述方式A,确定多个载波对应的在上行时隙n中传输的HARQ-ACK码本为8比特,然后对于一个DCI调 度一个PDSCH在载波1和载波2上传输,或者在其中一个载波上传输的情况下HARQ-ACK码本的产生和PDSCH的HARQ-ACK在码本中的映射位置的确定方式同上方式A中的描述,不再赘述;
当采用方式1-2时,则确定上行时隙n-1对应的M
c-max=max(3,2)=3,上行时隙n-2对应的M
c-max=max(4,3)=4,从而确定多个载波对应的在上行时隙n中传输的HARQ-ACK码本为7比特,前4比特对应上行时隙n-2对应的M
c-max=4个候选的下行传输机会(即包含了载波1和载波2在时隙n-2中的下行传输机会在内),后3比特对应上行时隙n-1对应的M
c-max=3个候选的下行传输机会(即包含了载波1和载波2在时隙n-1中的下行传输机会在内);如果在下行时隙n-1中存在一个被调度在载波1和载波2上传输的PDSCH,假设其SLIV对应的是其传输所在时隙中的候选的下行传输机会中第3个,即也就是对应了上行时隙n-1(与这个下行时隙n-1对应的上行时隙)对应的M
c-max=3个候选的下行传输机会中的第3个候选的下行传输机会,则该PDSCH的HARQ-ACK映射到上行时隙n-1对应的3比特HARQ-ACK中的第3比特位置(即7比特HARQ-ACK码本中的第7比特位置);如果在下行时隙n-2中存在一个被调度仅在载波2上传输的PDSCH,假设其SLIV对应的是载波2的时隙n-2中的候选的下行传输机会中的第1个(假设载波2上时隙n-2中的3个候选的下行传输机会对应上行时隙n-2对应的M
c-max=4个候选的下行传输机会中的前3个,则这个PDSCH对应的下行传输机会对应上行时隙n-2对应的M
c-max=4个候选的下行传输机会中的第1个候选的下行传输机会),则该PDSCH的HARQ-ACK映射到上行时隙n-2对应的4比特HARQ-ACK中的第1比特位置(即7比特HARQ-ACK码本中的第1比特位置);终端在上行时隙n中,在确定的PUCCH资源上发送7比特HARQ-ACK,如图2所示;基站按照上述同样的方式,可以确定终端在上行时隙n中发送了7比特HARQ-ACK码本,在对应的资源上进行接收,并按照上述同样方式可以从7比特HARQ-ACK码本中获得被调度的PDSCH的HARQ-ACK;
当采用方式1-3时,假设特定载波为载波1(可以是按照特定规则确定的, 或者信令预先通知的等方式得到的特定载波,具体方式不做限制),则确定上行时隙n-1对应的M
c-max=3(即为载波1上与上行时隙n-1对应的时隙n-1中包含的候选的下行传输机会的个数),上行时隙n-2对应的M
c-max=4(即为载波1上与上行时隙n-2对应的时隙n-2中包含的候选的下行传输机会的个数),进而具体的得到HARQ-ACK码本的方式同上方式1-2,不再赘述;其中,因为载波1上的每个时隙包含的候选的下行传输机会的个数都是不小于载波2在对应的时隙中包含的候选的下行传输机会的个数的,因此,即使基站发送一个DCI调度了一个PDSCH仅在载波2上的某个时隙中传输,则按照载波1的候选的下行传输机会确定的HARQ-ACK码本中总是能包含载波2上的下行传输在内,因为载波2的候选的下行传输机会的个数是载波1上对应的时隙中的候选的下行传输机会的个数的子集;
实施例2(方式2):当支持通过一个DCI调度一个PDSCH在载波1和载波2上传输时,假设载波1为特定载波,其他假设同上方式A和B,则可以根据现有技术对载波1确定HARQ-ACK码本,比如,在不进行SLIV有效性判断时,确定载波1上与上行时隙n-1和n-2分别对应的时隙n-1和n-2中都包含了4个候选的下行传输机会,从而得到8比特HARQ-ACK码本,也可以是根据现有技术确定载波1在时隙n-1和n-2中包含的候选的下行传输机会个数,然后将这个个数分别作为上行时隙n-1和n-2对应的候选的下行传输机会个数,进而得到8比特HARQ-ACK码本,对DCI调度的在载波1和载波2上同时传输的PDSCH或在某一个载波上传输的PDSCH进行HARQ-ACK映射的方式同方式A,此处不再赘述;
比如,在进行SLIV有效性判断时,确定载波1上与上行时隙n-1和n-2分别对应的时隙n-1和n-2中分别包含了3个和4个候选的下行传输机会,从而得到7比特HARQ-ACK码本,也可以是根据现有技术确定载波1在时隙n-1和n-2中包含的候选的下行传输机会个数,然后将这个个数分别作为上行时隙n-1和n-2对应的候选的下行传输机会个数,进而得到7比特HARQ-ACK码本,对DCI调度的在载波1和载波2上同时传输的PDSCH或在某一个载 波上传输的PDSCH进行HARQ-ACK映射的方式同方式B,此处不再赘述;
当DCI调度一个PDSCH在多个载波中没有包含特定载波在内的一个或多个载波上传输时,PDSCH的HARQ-ACK根据PDSCH对应的SLIV在所述特定载波上对应的第二时间单元中对应的候选下行传输机会进行映射(即这个PDSCH在载波2上的时隙n传输,载波1是特定载波,则需要在载波1上确定一个时隙,这个时隙是与载波2上的时隙n对应的时隙,例如这个时隙根据调度时序设计是在DCI同时调度两个载波时,与载波2上的时隙n同时被调度的时隙,比如根据同一个K0值可以确定的时隙,在载波1中的这个对应的时隙中找到一个与这个PDSCH使用的SLIV相同的SLIV,从而得到载波1的这个时隙中的一个与这个PDSCH对应的候选下行传输机会,进而根据这个候选的下行传输机会以载波1的这个时隙的位置,可以得到PDSCH的HARQ-ACK在载波1的HARQ-ACK码本中的映射位置。
上述实施例中,DCI调度一个PDSCH在载波1和载波2上传输时具体的调度实现方式不做限制,例如可以是DCI中包含分别针对载波1和载波2的调度指示信息,独立指示载波1和载波2上的调度信息(如时域资源(包括SLIV和K0)、频域资源、MCS、DMRS端口等),也可以是DCI中仅包含一套指示域,所提供的调度信息对两个载波共享,即例如DCI中的TDRA指示域指示了一个SLIV和K0,则在每个载波上都是按照这个SLIV和K0确定一个时域传输位置等,也可以是DCI中的部分指示域是对两个载波独立指示的,部分指示域是两个载波共享的,等等只要是能实现一个DCI调度一个PDSCH在多个载波上传输的方案,都可以应用在这里;
上述实施例中:将K1以时隙为单位替换为以子时隙为单位时,同样适用;载波1和载波2的SCS不同时,同样适用,一个DCI调度一个PDSCH在更多个载波上传输时,同样适用。
综上所述,本申请实施例提供的技术方案中,当一个DCI可以调度一个PDSCH在多个载波上传输时,多个载波作为一组共同确定一个HARQ-ACK,而不是分别对每个载波确定HARQ-ACK码本再级联在一起。即本申请实施例 给出了一种一个DCI调度一个PDSCH在多个载波上传输时,如何确定多个载波的HARQ-ACK码本的方法,避免根据现有技术分别对每个载波确定HARQ-ACK码本再级联在一起造成的码本冗余,保证了基站和终端对HARQ-ACK传输的理解一致性,降低了HARQ-ACK的冗余,提高了HARQ-ACK传输性能和效率。
在终端侧,参见图3,本申请实施例提供的一种信息传输方法包括:
S101、当一个下行控制信息DCI可以调度一个下行传输在多个载波上传输时,以所述多个载波为一组,确定一个混合自动重传请求确认HARQ-ACK码本;
其中,以所述多个载波为一组,确定一个混合自动重传请求确认HARQ-ACK码本,即:将这多个载波作为一组,对这一组载波产生一个HARQ-ACK码本。
S102、发送所述HARQ-ACK码本。
可选地(对应上述方式1),确定所述HARQ-ACK码本具体包括:

i,确定一个第一时间单元n-K1
i对应的候选的下行传输机会个数M
c-max;
