本公开涉及通信技术领域,特别是指一种混合自动重传请求应答的传输指示方法及设备。
第五代移动通信技术5G新空口NR系统中不支持物理上行控制信道PUCCH和物理上行共享信道PUSCH的同时传输,因此当PUCCH和PUSCH在时间上重叠时,需要将PUCCH承载的上行控制信息转移到PUSCH上和数据进行复用传输。当在PUSCH上复用传输混合自动重传请求应答HARQ-ACK时,需要结合调度PUSCH的下行控制信息DCI中的下行分配索引DAI指示域确定对应的HARQ-ACK码本。
具体的,当UE被配置使用半静态码本时,当UE将HARQ-ACK复用在DCI格式0_1调度的PUSCH上进行传输时,DCI中包含1比特DAI域用于指示在被调度的PUSCH上是否存在HARQ-ACK传输,如果DCI格式0_1中的DAI域值为1,UE依照PUSCH上对HARQ-ACK空间合并的配置,重用在PUCCH上确定HARQ-ACK码本的过程确定在PUSCH上传输的HARQ-ACK码本。如果调度PUSCH的DCI格式0_1中的DAI域值为0,当UE仅在主载波的集合中接收到一个半持续调度SPS PDSCH,或接收到一个由DCI格式1_0调度的PDSCH或一个指示SPS PDSCH释放的DCI格式1_0,且DCI格式1_0中的DAI值为1时,UE仅对收到的一个SPS PDSCH或者DCI格式1_0调度的PDSCH或者指示SPS PDSCH释放的DCI产生1比特HARQ-ACK;否则,UE不在PUSCH上复用HARQ-ACK传输。
当UE被配置使用动态码本时,如果UE被配置使用单载波传输,则在调 度PDSCH传输或者指示SPS PDSCH释放的DCI中仅包含2比特的C-DAI指示信息,无T-DAI。当UE将HARQ-ACK复用在DCI格式0_1调度的PUSCH上进行传输时,DCI中包含2或4比特DAI域用于指示在被调度的PUSCH上是否存在HARQ-ACK传输以及HARQ-ACK的比特数。如果UE没有被配置使用基于码块组CBG的数据传输,DCI格式0_1中包含2比特DAI。如果UE被配置使用基于CBG的数据传输,DCI格式0_1中包含4比特DA,其中2比特对应第一子码本,2比特对应第二子码本。
然而,当支持一个时隙中使用多个时分的PUCCH承载HARQ-ACK时,并不能确定如何将这些PUCCH上承载的HARQ-ACK都转移到PUSCH上进行复用传输。

图6为本公开另一实施例的混合自动重传请求应答的传输指示装置的流程示意图。
为使本公开要解决的技术问题、技术方案和优点更加清楚,下面将结合附图及具体实施例进行详细描述。
如图1所示,本公开的实施例提供一种混合自动重传请求应答的传输指示方法,包括:
步骤101,接收网络侧设备的下行分配索引DAI,其中DAI的信息域指示在物理上行共享信道PUSCH上传输多个混合自动重传请求应答HARQ-ACK码本。
通过上述步骤,本公开实施例的方法,应用于用户设备,会接收网络侧设备的DAI,由于该DAI的信息域指示了在PUSCH上传输多个HARQ-ACK码本,能够实现基于该DAI的信息域指示通过PUSCH复用传输多个HARQ-ACK码本,保证了PUSCH上复用多个HARQ-ACK码本时的传输性能。
可选地,所述接收网络侧设备的下行分配索引DAI,包括:
接收网络侧设备的下行控制信息DCI,其中所述DCI中携带所述DAI,所述DCI用于调度所述PUSCH。
这里,网络侧设备通过调度PUSCH的DCI携带该DAI告知于用户设备。
该实施例中,一方面,可选地,所述DAI的信息域包括N个子域,每个子域指示PUSCH上传输一个HARQ-ACK码本,N为大于或等于2的整数。
如此,将DAI的信息域分为N个子域,其中,N是最大可能在PUSCH上复用传输的HARQ-ACK码本个数,由每个子域指示PUSCH上传输一个HARQ-ACK码本。假设,最大可能在PUSCH上复用传输3个HARQ-ACK码本(HARQ-ACK码本1、HARQ-ACK码本2和HARQ-ACK码本3),即N=3,3个子域和3个HARQ-ACK码本一一对应,如此,DAI的信息域的3个子域(子域A、子域B和子域C),会指示PUSCH上传输一个对应的HARQ-ACK码本。如,子域A指示PUSCH上传输HARQ-ACK码本1,子域B指示PUSCH上传输HARQ-ACK码本2,子域C指示PUSCH上传输HARQ-ACK码本3。
可选地,所述N为:
一个时隙中配置的子时隙个数;或者
与DCI可调度的最大PUSCH的长度重叠的最大子时隙个数;或者
预定义的值;或者
高层信令配置的值。
这里,N可以是一个时隙中配置的子时隙个数,可以是与DCI可调度的 最大PUSCH的长度重叠的最大子时隙个数,可以是预定义的,可以是高层信令配置的。其中,若DCI可调度的最大PUSCH的长度是5个符号,而预先配置了1个时隙中的子时隙个数为7,即每个子时隙的长度是2个符号,则与DCI可调度的最大PUSCH的长度重叠的最大子时隙个数是3,即N=3。
可选地,所述N个子域的每个子域为X个比特,X为大于或等于1的整数。
如此,每个子域中,会通过X比特信息来完成PUSCH上传输一个HARQ-ACK码本的指示。
应该知道的是,HARQ-ACK码本主要分为半静态码本和动态码本,而动态码本还进一步分为是否配置CBG传输。故,在该实施例中,可选地,若当前子域对应的HARQ-ACK码本为半静态码本,则X=1;
若当前子域对应的HARQ-ACK码本为未配置码本组CBG传输的动态码本,则X=2;
若当前子域对应的HARQ-ACK码本为配置CBG传输的动态码本,则X=4。
如此,在当前子域对应的HARQ-ACK码本为半静态码本的情况下,可由该子域的1比特信息进行指示;在当前子域对应的HARQ-ACK码本为未配置CBG传输的动态码本的情况下,可由该子域的2比特信息进行指示;在当前子域对应的HARQ-ACK码本为配置CBG传输的动态码本的情况下,可由该子域的4比特信息进行指示。当然,DAI的信息域中的不同子域可包括不同的比特数量的信息。
该实施例中,另一方面,可选地,所述DAI的信息域包括Y比特的指示信息,所述指示信息联合指示多个HARQ-ACK码本在PUSCH的传输,Y为大于或等于1的整数。
这里,区别于子域与HARQ-ACK码本一一对应的指示,该DAI的信息域会通过Y比特的指示信息联合指示多个HARQ-ACK码本在PUSCH的传输。
可选地,所述多个HARQ-ACK码本均为半静态码本,Y=1;其中,
所述指示信息为1时表示所述多个HARQ-ACK码本全部在PUSCH上传 输,所述指示信息为0时表示所述多个HARQ-ACK码本全部未在PUSCH上传输。
如此,在多个HARQ-ACK码本均为半静态码本的情况下,1比特的指示信息为1,该多个HARQ-ACK码本全部在PUSCH上传输;1比特的指示信息为0,该多个HARQ-ACK码本全部未在PUSCH上传输。
可选地,所述多个HARQ-ACK码本均为未配置CBG传输的动态码本,Y=K,K为大于或等于1的整数;其中,
K比特信息指示所述多个HARQ-ACK码本对应的最大PDSCH的个数。
这里,在多个HARQ-ACK码本均为未配置CBG传输的动态码本的情况下,Y=K,K比特信息是基于该多个HARQ-ACK码本对应的最大PDSCH(最大调度PDSCH)的个数确定的,较优的,K值为2,即通过2比特指示多个HARQ-ACK码本对应的最大PDSCH的个数,若多个HARQ-ACK码本对应的最大PDSCH的个数为4,则K比特信息为11;若多个HARQ-ACK码本对应的最大PDSCH的个数为7,则K比特信息为10。
其中,在所述多个HARQ-ACK码本中,当前HARQ-ACK码本对应PDSCH的个数小于所述最大PDSCH的个数,则所述当前HARQ-ACK码本中的未收到PDSCH传输的反馈位置补充非确认NACK。
可选地,所述多个HARQ-ACK码本均为动态码本,且存在至少一个HARQ-ACK码本被配置CBG传输,Y=P+Q,P为大于或等于1的整数,Q为大于或等于1的整数;其中,
P比特信息指示所述多个HARQ-ACK码本中第一子码本或未配置CBG传输的HARQ-ACK码本对应的PDSCH的个数,Q比特信息指示所述多个HARQ-ACK码本中第二子码本对应的PDSCH的个数;
所述第一子码本为对应传输块TB传输的子码本,所述第二子码本为对应CBG传输的子码本。
这里,在多个HARQ-ACK码本均为动态码本,且存在至少一个HARQ-ACK码本被配置CBG传输的情况下,Y比特指示信息分为两部分:P比特信息和Q比特信息。其中,P比特信息指示该多个HARQ-ACK码本中第一子码本或未配置CBG传输的HARQ-ACK码本对应的PDSCH的个数, Q比特信息指示该多个HARQ-ACK码本中第二子码本对应的PDSCH的个数。
例如,P=2,Q=2,DAI信息域通过4比特信息联合指示在PUSCH上传输该多个HARQ-ACK码本。其中,前2比特信息指示该多个HARQ-ACK码本中第一子码本或未配置CBG传输的HARQ-ACK码本对应的PDSCH的个数,后2比特信息指示该多个HARQ-ACK码本中第二子码本对应的PDSCH的个数。
可选地,所述多个HARQ-ACK码本包括半静态码本和动态码本,且全部的动态码本均未配置CBG传输,Y=1+K;其中,1比特信息指示PUSCH上是否传输所述多个HARQ-ACK码本中的所有半静态码本。
这里,在多个HARQ-ACK码本包括半静态码本和动态码本,且全部的动态码本均未配置CBG传输的情况下,Y比特指示信息分为两部分:1比特信息和K比特信息。其中,1比特信息指示PUSCH上是否传输该多个HARQ-ACK码本中的所有半静态码本,该1比特信息为1时表示该多个HARQ-ACK码本中的所有半静态码本全部在PUSCH上传输,该1比特信息为0时表示该多个HARQ-ACK码本中的所有半静态码本全部未在PUSCH上传输。而K比特信息类似于上述多个HARQ-ACK码本均为未配置CBG传输的动态码本的情况,指示该多个HARQ-ACK码本中使用动态码本的HARQ-ACK码本对应的最大PDSCH的个数。
可选地,所述多个HARQ-ACK码本包括半静态码本和动态码本,且存在至少一个动态码本被配置CBG传输,Y=1+P+Q;其中,
1比特信息指示所述多个HARQ-ACK码本中的所有半静态码本是否在PUSCH上传输。
这里,在多个HARQ-ACK码本包括半静态码本和动态码本,且至少一个动态码本被配置CBG传输的情况下,Y比特指示信息分为三部分:1比特信息、P比特信息和Q比特信息。其中,1比特信息指示PUSCH上是否传输该多个HARQ-ACK码本中的所有半静态码本,该1比特信息为1时表示该多个HARQ-ACK码本中的所有半静态码本全部在PUSCH上传输,该1比特信息为0时表示该多个HARQ-ACK码本中的所有半静态码本全部未在PUSCH上传输。P比特信息和Q比特信息类似于上述多个HARQ-ACK码本 均为动态码本,且存在至少一个HARQ-ACK码本被配置CBG传输的情况,P比特信息指示该多个HARQ-ACK码本中使用动态码本的HARQ-ACK码本中,第一子码本或未配置CBG传输的HARQ-ACK码本对应的PDSCH的个数;Q比特信息指示该多个HARQ-ACK码本中使用动态码本的HARQ-ACK码本中,第二子码本对应的PDSCH的个数。
可选地,所述多个HARQ-ACK码本包括半静态码本和动态码本,Y为大于或等于2的整数;其中,
对于半静态码本的HARQ-ACK码本,在用户设备未接收到对应的PDSCH传输,且所述指示信息指示不存在对应的PDSCH传输的情况下,所述PUSCH上不传输半静态码本的HARQ-ACK码本;反之,所述PUSCH上传输半静态码本的HARQ-ACK码本;
对于动态码本的HARQ-ACK码本,在用户设备未接收到对应的PDSCH传输,且所述指示信息指示不存在对应的PDSCH传输的情况下,所述PUSCH上不传输动态码本的HARQ-ACK码本;反之,所述PUSCH上传输动态码本的HARQ-ACK码本。
这里,在多个HARQ-ACK码本包括半静态码本和动态码本的情况下,不论是被配置使用半静态码本的HARQ-ACK码本,还是被配置使用动态码本的HARQ-ACK码本,在用户设备未接收到对应的PDSCH传输,且Y比特指示信息指示不存在对应的PDSCH传输的情况下,PUSCH上不传输该HARQ-ACK码本;反之,PUSCH上传输该HARQ-ACK码本。
下面,结合具体场景说明本公开实施例的方法的应用:
场景一、用户设备被配置了一个载波用于传输超可靠、低时延通信URLLC业务,使用15kHz的子载波间隔进行传输,在一个时隙中被配置了两个子时隙用于HARQ-ACK反馈,因此在这个载波上传输的PUSCH中最多可能有两个HARQ-ACK码本进行复用传输。
情况1,该用户设备在当前载波上被配置使用半静态码本进行HARQ-ACK反馈,DAI信息域中包含2比特分别指示两个HARQ-ACK码本在PUSCH上的传输情况。这里,DAI信息域中包含2个子域,每个子域包含1比特信息,即N=2,X=1。
如果DAI的信息域为00,则指示没有HARQ-ACK在当前PUSCH上复用传输;
如果DAI的信息域为10,则指示PUSCH所在时隙的第一个子时隙中的HARQ-ACK需要在当前PUSCH上进行复用传输;
如果DAI的信息域为01,则指示PUSCH所在时隙的第二个子时隙中的HARQ-ACK需要在当前PUSCH上进行复用传输;
如果DAI的信息域为11,则指示PUSCH所在时隙的两个子时隙中的HARQ-ACK都需要在当前PUSCH上进行复用传输。
情况2,该用户设备在当前载波上被配置使用半静态码本进行HARQ-ACK反馈,DAI信息域中包含1比特联合指示两个HARQ-ACK码本在PUSCH上的传输情况,即Y=1。
如果DAI的信息域为0,则指示没有HARQ-ACK在当前PUSCH上复用传输;
如果DAI的信息域为1,则指示PUSCH所在时隙的第一个子时隙中的HARQ-ACK和PUSCH所在时隙的第二个子时隙中的HARQ-ACK都需要在当前PUSCH上进行复用传输。
情况3,该用户设备在当前载波上被配置使用动态码本进行HARQ-ACK反馈且没有被配置CBG传输,DAI信息域中包含4比特指示两个HARQ-ACK码本在PUSCH上的传输情况。这里,DAI信息域中包含2个子域,每个子域包含2比特信息,其中前2个比特对应PUSCH所在时隙的第一个子时隙中的HARQ-ACK码本在PUSCH上的复用传输情况,后2个比特对应PUSCH所在时隙的第二个子时隙中的HARQ-ACK码本在PUSCH上的复用传输情况,即N=2,X=2。
假设DAI的信息域为0111,前2比特信息指示PUSCH所在时隙的第一个子时隙中的HARQ-ACK码本对应2个需要反馈的PDSCH传输,后两比特指示PUSCH所在时隙的第二个子时隙中的HARQ-ACK码本对应4个需要反馈的PDSCH传输。假设PDSCH均为基于TB的传输,用户设备确定在PUSCH上反馈的HARQ-ACK码本包含2+4即6比特。因此,当用户设备正确接收到所有PDSCH传输时,用户设备反馈111111。
情况4,该用户设备在当前载波上被配置使用动态码本进行HARQ-ACK反馈且没有被配置CBG传输,DAI信息域中包含2比特联合指示两个HARQ-ACK码本在PUSCH上的传输情况,即Y=K=2。
假设DAI的信息域为11,指示PUSCH所在时隙的第一个子时隙中的HARQ-ACK码本对应4个需要反馈的PDSCH传输,PUSCH所在时隙的第二个子时隙中的HARQ-ACK码本也对应4个需要反馈的PDSCH传输。假设PDSCH均为单个TB的传输,用户设备确定在PUSCH上反馈的HARQ-ACK码本包含4+4即8比特。因此,当用户设备正确接收到所有PDSCH传输时,用户设备反馈10001111。由于DAI的信息域K值是按照多个HARQ-ACK码本对应的最大PDSCH的个数设置的,基站实际可能没有调度这么多的PDSCH传输,反馈码本中的第1~4比特“1000”代表基站实际调度了1个PDSCH传输需要在PUSCH所在时隙的第一个子时隙中的HARQ-ACK码本进行反馈。
情况5,用户设备在当前载波上被配置使用动态码本进行HARQ-ACK反馈且被配置CBG传输,DAI信息域中包含8比特指示两个HARQ-ACK码本在PUSCH上的传输情况。这里,DAI信息域中包含2个子域,每个子域包含4比特信息,其中前4个比特信息对应PUSCH所在时隙的第一个子时隙中的HARQ-ACK码本在PUSCH上的复用传输情况,后4个比特信息对应PUSCH所在时隙的第二个子时隙中的HARQ-ACK码本在PUSCH上的复用传输情况,即N=2,X=4。
假设DAI的信息域为11100100,指示PUSCH所在时隙的第一个子时隙中的第一HARQ-ACK子码本对应4个需要反馈的PDSCH传输,PUSCH所在时隙的第一个子时隙中的第二HARQ-ACK子码本对应3个需要反馈的PDSCH传输,PUSCH所在时隙的第二个子时隙中的第一HARQ-ACK子码本对应2个需要反馈的PDSCH传输,PUSCH所在时隙的第二个子时隙中的第二HARQ-ACK子码本对应1个需要反馈的PDSCH传输。假设被配置的CBG个数为2,用户设备确定在PUSCH上反馈的HARQ-ACK码本包含4+3*2+2+1*2即14比特,其中前4个比特对应PUSCH所在时隙的第一个子时隙中的第一HARQ-ACK子码本,第5~10比特对应PUSCH所在时隙的第 一个子时隙中的第二HARQ-ACK子码本,第11~12比特对应PUSCH所在时隙的第二个子时隙中的第一HARQ-ACK子码本,13~14比特对应PUSCH所在时隙的第二个子时隙中的第二HARQ-ACK子码本。
情况6,用户设备在当前载波上被配置使用动态码本进行HARQ-ACK反馈且被配置CBG传输,DAI信息域中包含4比特联合指示两个HARQ-ACK码本在PUSCH上的传输情况,即Y=P+Q=2+2。
假设DAI的信息域为0101,指示PUSCH所在时隙的两个子时隙中的第一HARQ-ACK子码本都对应2个需要反馈的PDSCH传输,PUSCH所在时隙的两个子时隙中的第二HARQ-ACK子码本都对应2个需要反馈的PDSCH传输。假设被配置的CBG个数为2,用户设备确定在PUSCH上反馈的HARQ-ACK码本包含2+2*2+2+2*2即12比特,其中前2个比特对应PUSCH所在时隙的第一个子时隙中的第一HARQ-ACK子码本,第3~6比特对应PUSCH所在时隙的第一个子时隙中的第二HARQ-ACK子码本,第7~8比特对应PUSCH所在时隙的第二个子时隙中的第一HARQ-ACK子码本,第9~12比特对应PUSCH所在时隙的第二个子时隙中的第二HARQ-ACK子码本。当用户设备正确接收到所有PDSCH传输时,用户设备反馈111111101100。由于DAI的信息域是按照多个子码本对应的最大值设置的,基站实际可能没有调度这么多的PDSCH传输,例如反馈码本中的第7~8比特“10”代表基站实际调度了1个PDSCH传输需要在PUSCH所在时隙的第二个子时隙中的第一HARQ-ACK码本进行反馈,以及第9~12比特“1100”代表基站实际调度了1个基于CBG的PDSCH传输需要在PUSCH所在时隙的第二个子时隙中的第二HARQ-ACK码本进行反馈。
场景二、用户设备在一个载波上被同时配置增强移动宽带eMBB和URLLC业务,均使用15kHz的子载波间隔进行传输,在一个时隙中被配置了两个子时隙用于HARQ-ACK反馈,因此在这个载波上传输的PUSCH中最多可能有三个HARQ-ACK码本进行复用传输,其中一个是eMBB的HARQ-ACK反馈码本,两个是URLLC的HARQ-ACK反馈码本。eMBB被配置使用半静态码本反馈,URLLC业务被配置使用动态码本进行HARQ-ACK反馈且没有被配置CBG传输,DAI信息域指示三个HARQ-ACK 码本在PUSCH上的传输情况。
情况1,DAI信息域中包含3比特联合指示三个HARQ-ACK码本在PUSCH上的传输情况,即Y=1+K=1+2。
假设DAI的信息域为101,其中第1个比特指示半静态码本都需要在PUSCH上进行复用传输,后两个比特指示所有动态码本都对应2个需要反馈的PDSCH传输。假设eMBB的半静态码本对应5比特反馈信息,则用户设备确定在PUSCH上反馈的HARQ-ACK码本一共包含5+2+2即9比特,当用户设备正确接收到所有PDSCH传输时,用户设备反馈100111100。前5个比特对应半静态码本,其中的0表示基站没有在对应的PDSCH传输位置调度传输,第6~7比特对应PUSCH所在时隙的第一个子时隙的动态码本,第8~9比特对应PUSCH所在时隙的第二个子时隙的动态码本,由于DAI的信息域K值是按照多个HARQ-ACK码本对应的最大PDSCH的个数设置的,基站实际可能没有调度这么多的PDSCH传输,反馈码本中的第8~9比特“00”代表基站实际没有调度需要在PUSCH所在时隙的第二个子时隙进行反馈的URLLC PDSCH传输。
情况2:DAI的信息域中包含2比特联合指示三个HARQ-ACK码本在PUSCH上的传输情况,即Y=2。
假设DAI的信息域为01,指示半静态码本都需要在PUSCH上进行复用传输,所有动态码本都对应2个需要反馈的PDSCH传输。用户设备UE的实际反馈行为和上面情况1一样。
情况3:DAI的信息域中包含2比特联合指示三个HARQ-ACK码本在PUSCH上的传输情况,即Y=2。
假设DAI指示为11,如果UE接收到了半静态码本对应的PDSCH传输,这两个比特代表半静态码本都需要在PUSCH上进行复用传输;如果UE没有接收到半静态码本对应的PDSCH传输,这两个比特代表PUSCH上没有半静态码本需要进行复用传输。对于任一个动态码本,如果UE接收到了对应的PDSCH传输,则这两个比特指示对应的动态码本需要在PUSCH上进行复用传输,并基于接收到的PDSCH和对应的下行DAI确定对应的动态码本在PUSCH复用传输的HARQ-ACK反馈比特数。例如,UE接收到了一个下行 DAI为2和一个下行DAI为3的PDSCH传输,需要在PUSCH传输时隙的第一个子时隙进行反馈,UE基于上行DAI确定对应的反馈比特数为4,当这两个PDSCH传输都被正确接收时,UE对这个动态码本反0110;同时,UE接收到了一个下行DAI为2和一个下行DAI为3和一个下行DAI为4的PDSCH传输,需要在PUSCH传输时隙的第二个子时隙进行反馈,UE基于上行DAI确定对应的反馈比特数为4,当这三个PDSCH传输都被正确接收时,UE对这个动态码本反0111。在UE正确接收到所有半静态码本和动态码本对应的PDSCH传输的情况下,UE在PUSCH复用传输的HARQ-ACK码本为1100101100111,其中前5个比特对应半静态码本,其中的0表示基站没有在对应的PDSCH传输位置调度传输,第6~9比特对应PUSCH所在时隙的第一个子时隙的动态码本,第10~13比特对应PUSCH所在时隙的第二个子时隙的动态码本。
应该了解的是,该实施例中,用户设备接收到网络侧设备的DAI后,基于该DAI的信息域,就能够进一步将多个HARQ-ACK在PUSCH上的传输。
