下面结合本申请另一个实施例进行说明。
相关技术中对于HARQ-ACK码本的大小确定以及对应的PUCCH资源是通过下面的方式确定的。图3是根据相关技术中的HARQ-ACK反馈的示意图，如图3所示，有4个PDSCH分别被DCI调度且在DCI中配置了对应的反馈HARQ-ACK的slot位置(通过k1指示，k1为slot间隔数)，以及在slot n+k1(n表示PDSCH被传输的slot)的slot中对应的PUCCH资源(通过PRI指示)。进一步的由于这4个PDSCH的DCI中k1的取值指示的是同一上行slot，所以，这些DCI中最后一个DCI指示的PRI是最终反馈这4个PDSCH对应的HARQ-ACK的PUCCH资源(即，把这4个PDSCH各自对应HARQ-ACK信息串接后作为一个HARQ-ACK码本，再在PUCCH资源中传输)。如，第一个PDSCH对应的DCI中包含k1＝4，PRI＝0；第二个PDSCH对应的DCI中包含k1＝3，PRI＝1；第三个PDSCH对应的DCI包含k1＝2，PRI＝0；第四个PDSCH对应的DCI中包含k1＝1，PRI＝0。进一步的相关技术中，还包括根据反馈HARQ-ACK的比特数，确定对应的PUCCH集合，在根据PRI指示，从对应的集合中选择被PRI指示的PUCCH资源。且相关技术规定，PUCCH set0中的PUCCH资源只能传输1～2bit的UCI(包括HARQ-ACK)信息，其余的PUCCH set中，也有对应的传输UCI(包含HARQ-ACK)信息范围，且PUCCH set对应的UCI信息范围彼此不重叠。例如，有2个PUCCH set，PUCCH set0传输的UCI信息范围为1～2bit，PUCCH set1传输的UCI信息范围为大于2bit。这样，图3中，第一个PDSCH的DCI指示的PRI＝0，和第三个PDSCH的DCI指示的PRI＝0，但是它们实际只是的PUCCH资源是属于不同PUCCH set，所以，是属于不同给的PUCCH资源。
相关技术中，总是从指示了相同的反馈HARQ-ACK的slot的多个DCI中选择最后一个(末尾)DCI中指示的PUCCH资源作为所述多个DCI对应的PDSCH的HARQ-ACK反馈的PUCCH资源。这样，图3中，实际上4个PDSCH的HARQ-ACK被复用在一起，且只能使用第4个PDSCH对应的DCI中指示的PUCCH资源来承载。显然，相关技术中机制无法实现将图3中，前面几个PDSCH的HARQ-ACK反馈的PUCCH资源和后面几个PDSCH的HARQ-ACK反馈的PUCCH资源区分为2个。
这样相当于，前面几个PDSCH的HARQ-ACK不能在图3示意UL slot中的时域上靠前的PUCCH中反馈，最终导致它们的HARQ-ACK反馈存在延时。这也是因为最后一个DCI对应的PDSCH的HARQ-ACK准备需要一定的处理时间，所以靠后的PDSCH的HARQ-ACK对应的PUCCH资源只能在图3示意的UL slot中靠后的位置。恰好的，根据相关技术中，前面的PDSCH的HARQ-ACK只能在末尾DCI指示的PUCCH资源中传输。这样前面PDSCH的HARQ-ACK反馈存在时延了。相关技术机制也可以被总结为，在一个UL slot中只有一次HARQ-ACK传输机会。
如果上述PDSCH为超可靠低时延URLLC的PDSCH，显然，相关技术机制将延迟前面的URLLC PDSCH的HARQ-ACK的反馈，这种延时对于URLLC是不可接受的，因为它对于业务的及时性要求非常苛刻。所以，针对URLLC业务的HARQ-ACK反馈的情况，需要考虑优化相关技术机制，减少上述的HARQ-ACK反馈延时，也就是说，需要给出一种办法实现在一个UL slot中实现多次HARQ-ACK传输机会(文中，以slot为单位进行说明，实际上slot可以替换为其他单位，例如子时隙subslot，或者连续的几个OFDM符号构成一个单位，或多个slot或subslot构成一个单位，但是处理都是相同)。
在本申请另一个实施例中存在以下具体实施例。
下面所有具体实施例中，关于根据HARQ-ACK码本大小或比特数确定PUCCH set，再根据PRI在确定的PUCCH set中选择对应的PUCCH资 源。这里显然，不仅仅限于HARQ-ACK码本大小，可以是待传输的UCI比特数，这里UCI可以包含HARQ-ACK，SR和CSI，然后根据待传输UCI的比特确定PUCCH set，再根据PRI在确定的PUCCH set中选择对应的PUCCH资源。
具体实施例1：
在物理层引入一个参数，优先考虑DCI中设置该参数。利用该参数确定DCI中指示的PUCCH资源是否为一个有效的反馈HARQ-ACK码本的PUCCH资源(DCI指示的PUCCH资源，未特殊声明，PUCCH资源是被DCI中的PRI指示的。如果PRI有其他声明，则以其他声明为准，下面所有实施例，类似)。这里的上行单元，可以是上行子帧、时隙、子时隙等，也可以是由连续的n个OFDM符号构成的单元，n值可以预配置，且n个OFDM符号构成的单元中，n值可以不同。后续的具体实施例中的关于上行单元的描述与此处相同。
在一个或多个DCI中指示了相同的上行单元来反馈所述DCI调度的PDSCH的HARQ-ACK信息时，在所述DCI中包含所述参数，使用所述参数来指示当前DCI指示的PUCCH资源是否为一个有效的反馈HARQ-ACK的PUCCH资源。
相对于非有效的反馈HARQ-ACK的PUCCH资源，一个有效的反馈HARQ-ACK的PUCCH资源能够替换之前的非有效PUCCH资源，是被认为需要传输HARQ-ACK码本的PUCCH资源(或者说有效的PUCCH资源替换掉之前非有效的PUCCH资源，且把非有效的PUCCH资源计划发送的HARQ-ACK也在有效PUCCH资源中传输)。
如果接收的当前DCI指示的PUCCH资源被标记为有效的PUCCH资源，则将当前DCI之前(也包括当前DCI)接收的DCI对应的(也是调度的)PDSCH的HARQ-ACK信息复用在一起，作为一个HARQ-ACK码本，在当前DCI指示的PUCCH资源中发送。注意，所述当前DCI之前，向前的截止位置是上一次的HARQ-ACK码本对应的末尾DCI之后开始的。
例如，参数为1bit开销，1bit为1表示为一个有效的反馈HARQ-ACK的PUCCH资源，为0表示不是一个有效的反馈HARQ-ACK的PUCCH资源。
如果直到所述上行单元中被指示的PUCCH资源处(这里是指，在上行单元中被指示的PUCCH资源之前N1+X时长处，其中N1+X至少包括：UE处理PDSCH，和形成对应HARQ-ACK的时间)，UE接收到的所述DCI中的参数取值均为0，则使用接收的所述DCI中末尾DCI中指示的PUCCH资源作为一个有效的PUCCH资源，且将所述DCI对应的PDSCH的HARQ-ACK复用在一起，作为一个HARQ-ACK码本在该有效PUCCH资源中传输。这种方式能有效克服基站在当前DCI调度PDSCH时，不能预测后续是否还有DCI调度PDSCH的情况。
另外，所述参数也可以考虑采用前后DCI中所述参数的比特取值是否反转来表达对应的DCI指示的PUCCH资源是否为一个有效的PUCCH资源。例如，参数取值发生反转的DCI中指示的PUCCH资源为一个有效的反馈HARQ-ACK的PUCCH资源。如果直到所述上行单元中被指示的PUCCH资源处(这里是指，在上行单元中被指示的PUCCH资源之前N1+X时长处，其中N1+X至少包括：UE处理PDSCH，和形成对应HARQ-ACK的时间)，UE接收到的所述DCI中的参数取值均未发生反转，则使用接收的所述DCI中末尾DCI中指示的PUCCH资源作为一个有效的PUCCH资源，且将所述DCI对应的PDSCH的HARQ-ACK复用在一起，作为一个HARQ-ACK码本在该有效PUCCH资源中传输。这种方式能有效克服基站在当前DCI调度PDSCH时，不能预测后续是否还有DCI调度PDSCH的情况。
一个例子如图4所示，图4是根据本申请另一个实施例的具体实施例1的示意图，如图4所示，假设4个PDSCH被DCI调度，且DCI中携带有K1，PRI和所述参数取值，且这些K1指向相同的UL slot(如，第一个PDSCH在DL slot n，K1＝4，那么K1指向的slot为slot n+K1，k1的单位为slot；K1也可以是subslot等单位，此时就假设K1指向了相同的subslot， 处理机制是相同的)，图4中在一个被指向的UL slot中有2个PUCCH资源，第一个PDSCH的DCI的PRI指向了该UL slot中的第一个PUCCH资源。此时第一个PDSCH的DCI中所述参数设置为0，即该DCI中PRI指示的PUCCH资源为非有效PUCCH资源。类似的第二个PDSCH的DCI中，K1＝3，PRI＝1，指向与第一个PDSCH对应的DCI指向的UL slot相同的UL slot，且所述参数置为1，此时就可以确认第二个PDSCH对应的DCI指示的PUCCH资源为一个有效的PUCCH资源。这样，就将该DCI之前(包含当前)接收的DCI对应的PDSCH的HARQ-ACK复用在一起，作为一个HARQ-ACK码本，在这个有效的PUCCH资源中传输。也即是，第一个PDSCH和第二个PDSCH的HARQ-ACK复用在一起作为一个HARQ-ACK码本，并在第二个PDSCH的DCI指示的PUCCH资源中传输所述HARQ-ACK码本。第3个PDSCH对应的DCI中K1＝2，PRI＝0，此时所述参数设置为0，第四个PDSCH对应的DCI中K1＝1，PRI＝0，此时所述参数设置为1，这样，第四个PDSCH的DCI中指示了一个有效的PUCCH资源，这样，第4个PDSCH对应DCI之前(包含)接收到DCI对应的PDSCH的HARQ-ACK复用在一起，作为一个HARQ-ACK码本，在该有效的PUCCH资源中传输。这个HARQ-ACK码本实际包含第3个PDSCH和第4个PDSCH的HARQ-ACK(为什么没有第1,2个PDSCH的HARQ-ACK，因为第1,2个PDSCH的HARQ-ACK作为一个HARQ-ACK已经在第2个PDSCH的DCI指示的有效PUCCH资源中传输了，也是前一次HARQ-ACK码本末尾DCI之后的DCI开始的，即第3个PDSCH的DCI直到当前DCI被选中)复用在一起，作为一个HARQ-ACK码本，并在第4个PDSCH的DCI指示的PUCCH资源传输。
还有一个特例，例如，如果第1，2，3，4的PDSCH的DCI中(假设K1均指向同一slot，如图4)，所述参数取值均为0，那么此时就以末尾DCI中的PRI指示的PUCCH资源作为有效PUCCH资源，且将接收到的所述DCI对应的PDSCH对应的HARQ-ACK复用在一起，作为一个HARQ-ACK码本，在所述有效PUCCH资源中传输。另外，需要注意， 末尾DCI调度的PDSCH满足一个条件，即末尾DCI调度的PDSCH需要一定的时间解码和形成对应的HARQ-ACK信息，假设这些需要N1+X时长，那么末尾DCI调度的PDSCH的末尾和末尾DCI中指示的PUCCH资源的开始之间至少间隔N1+X时长，这样才能保证末尾DCI调度的PDSCH能被及时的解码并形成HARQ-ACK信息。N1+X可以根据UE的硬件能力确定出来。
具体实施例2：
具体实施例2中类似具体实施例1，也是需要在物理层信令中引入一个参数，优选在DCI中增加这个参数，参数用来描述当前DCI对应的(即DCI调度的PDSCH)PDSCH的HARQ-ACK是否为一个HARQ-ACK码本的末尾HARQ-ACK。如果是，则当前DCI指示的PUCCH资源为一个有效的PUCCH资源。
相对于非有效的反馈HARQ-ACK的PUCCH资源，一个有效的反馈HARQ-ACK的PUCCH资源能够替换之前的非有效PUCCH资源，是被认为需要传输HARQ-ACK码本的PUCCH资源(或者说有效的PUCCH资源替换掉之前非有效的PUCCH资源，且把非有效的PUCCH资源计划发送的HARQ-ACK也在有效PUCCH资源中传输)。
如果接收的当前DCI中所述参数指示该DCI对应的PDSCH的HARQ-ACK是一个HARQ-ACK码本的末尾HARQ-ACK，则将当前DCI之前(也包括当前DCI)接收的DCI调度的PDSCH的HARQ-ACK信息复用在一起，在当前DCI指示的有效的PUCCH资源中发送。注意，所述当前DCI之前，向前的截止位置是上一次的HARQ-ACK码本对应的末尾DCI之后开始的。
例如，参数为1bit开销，1bit为1表示为该DCI对应的PDSCH的HARQ-ACK是一个HARQ-ACK码本的末尾HARQ-ACK；1bit为0表示该DCI对应的PDSCH的HARQ-ACK不是一个HARQ-ACK码本的末尾HARQ-ACK。
另外，本方式包含下面的实施，如果直到所述上行单元中被指示的PUCCH资源处(这里是指，在上行单元中被指示的PUCCH资源之前N1+X时长处，其中N1+X至少包括：UE处理PDSCH，和形成对应HARQ-ACK的时间)，UE接收到的所述DCI中的参数取值均为0，则将接收的所述DCI对应的PDSCH的HARQ-ACK复用在一起，作为一个HARQ-ACK码本，且认为所述DCI中的末尾DCI中指示的PUCCH资源作为一个有效的PUCCH资源，且将所述HARQ-ACK码本在所述有效PUCCH资源中传输。这种方式能有效克服基站在当前DCI调度PDSCH时，不能预测后续是否还有DCI调度PDSCH的情况。
另外，所述参数也可以考虑采用前后DCI中所述参数的比特取值是否反转来表达对应的DCI对应的PDSCH的HARQ-ACK是否为一个HARQ-ACK码本的末尾HARQ-ACK。例如，参数取值发生反转的DCI对应的PDSCH的HARQ-ACK为一个HARQ-ACK码本的末尾HARQ-ACK。如果直到所述上行单元中被指示的PUCCH资源处(这里是指，在上行单元中被指示的PUCCH资源之前N1+X时长处，其中N1+X至少包括：UE处理PDSCH，和形成对应HARQ-ACK的时间)，UE接收到的所述DCI中的参数取值均未发生反转，则使用接收的所述DCI中末尾DCI中指示的PUCCH资源作为一个有效的PUCCH资源，且将所述DCI对应的PDSCH的HARQ-ACK复用在一起，作为一个HARQ-ACK码本在该有效PUCCH资源中传输。这种方式能有效克服基站在当前DCI调度PDSCH时，不能预测后续是否还有DCI调度PDSCH的情况。
一个例子如图4所示。假设4个PDSCH被DCI调度，且DCI中携带有K1，PRI和所述参数取值，且这些K1指向相同的UL slot(如，第一个PDSCH在DL slot n，K1＝4，那么K1指向的slot为slot n+K1，k1的单位为slot；K1也可以是subslot等单位，此时就假设K1指向了相同的subslot，处理机制是相同的)，图4中在一个被指向的UL slot中有2个PUCCH资源，第一个PDSCH的DCI的PRI指向了该UL slot中的第一个PUCCH资源。此时第一个PDSCH的DCI中所述参数设置为0，即该DCI对应的 PDSCH的HARQ-ACK不是一个HARQ-ACK码本的末尾HARQ-ACK。类似的第二个PDSCH的DCI中，K1＝3，PRI＝1，指向与第一个PDSCH对应的DCI指向的UL slot相同的UL slot，且所述参数置为1，此时就可以确认第二个PDSCH对应的HARQ-ACK是为一个HARQ-ACK码本的末尾HARQ-ACK，且该DCI中指示的PUCCH资源为一个有效的PUCCH资源。这样，就将该DCI之前(包含当前)接收的DCI对应的PDSCH的HARQ-ACK复用在一起，作为一个HARQ-ACK码本，在这个有效的PUCCH资源中传输。也即是，第一个PDSCH和第二个PDSCH的HARQ-ACK复用在一起作为一个HARQ-ACK码本，并在第二个PDSCH的DCI指示的PUCCH资源中传输所述HARQ-ACK码本。第3个PDSCH对应的DCI中K1＝2，PRI＝0，此时所述参数设置为0，第4个PDSCH对应的DCI中K1＝1，PRI＝0，此时所述参数设置为1，这样，第四个PDSCH对应的HARQ-ACK是为一个HARQ-ACK码本的末尾HARQ-ACK，且该DCI中指示的PUCCH资源为一个有效的PUCCH资源，这样，第4个PDSCH对应DCI之前(包含)接收到DCI对应的PDSCH的HARQ-ACK复用在一起，作为一个HARQ-ACK码本，在该有效的PUCCH资源中传输。这个HARQ-ACK码本实际包含第3个PDSCH和第4个PDSCH的HARQ-ACK(为什么没有第1,2个PDSCH的HARQ-ACK，因为第1,2个PDSCH的HARQ-ACK作为一个HARQ-ACK已经在第2个PDSCH的DCI指示的有效PUCCH资源中传输了，也是前一次HARQ-ACK码本末尾DCI之后的DCI开始的，即第3个PDSCH的DCI直到当前DCI被选中)复用在一起，作为一个HARQ-ACK码本，并在第4个PDSCH的DCI指示的PUCCH资源传输。
还有一个特例，例如，如果第1，2，3，4的PDSCH的DCI中(假设K1均指向同一slot，如图4)，所述参数取值均为0，那么此时就以末尾DCI中的PRI指示的PUCCH资源作为有效PUCCH资源，且将接收到的所述DCI对应的PDSCH对应的HARQ-ACK复用在一起，在所述有效PUCCH资源中传输。另外，需要注意，末尾DCI调度的PDSCH满足一 个条件，即末尾DCI调度的PDSCH需要一定的时间解码和形成对应的HARQ-ACK信息，假设这些需要N1+X时长，那么末尾DCI调度的PDSCH的末尾和末尾DCI中指示的PUCCH资源的开始之间至少间隔N1+X时长，这样才能保证末尾DCI调度的PDSCH能被及时的解码并形成HARQ-ACK信息。N1+X可以根据UE的硬件能力确定出来。
具体实施例3：
具体实施例3中类似具体实施例1，也是需要在物理层信令中引入一个参数，优选在DCI中增加这个参数，参数用来描述当前DCI是否为一个HARQ-ACK码本对应的PDSCH中末尾的PDSCH对应的DCI。如果是，则当前DCI指示的PUCCH资源为一个有效的PUCCH资源。
相对于非有效的反馈HARQ-ACK的PUCCH资源，一个有效的反馈HARQ-ACK的PUCCH资源能够替换之前的非有效PUCCH资源，是被认为需要传输HARQ-ACK码本的PUCCH资源(或者说有效的PUCCH资源替换掉之前非有效的PUCCH资源，且把非有效的PUCCH资源计划发送的HARQ-ACK也在有效PUCCH资源中传输)。
如果接收的当前DCI中所述参数指示该DCI对应的PDSCH的HARQ-ACK是一个HARQ-ACK码本的末尾HARQ-ACK，则将当前DCI之前(也包括当前DCI)接收的DCI调度的PDSCH的HARQ-ACK信息复用在一起，在当前DCI指示的有效的PUCCH资源中发送。注意，所述当前DCI之前，向前的截止位置是上一次的HARQ-ACK码本对应的末尾DCI之后开始的。
例如，参数为1bit开销，1bit为1表示为该DCI为一个HARQ-ACK码本对应的PDSCH中末尾的PDSCH对应的DCI；1bit为0表示该DCI不是一个HARQ-ACK码本对应的PDSCH中末尾的PDSCH对应的DCI。
另外，本方式包含下面的实施，如果直到所述上行单元中被指示的PUCCH资源处(这里是指，在上行单元中被指示的PUCCH资源之前N1+X时长处，其中N1+X至少包括：UE处理PDSCH，和形成对应HARQ-ACK 的时间)，UE接收到的所述DCI中的参数取值均为0，则将接收的所述DCI对应的PDSCH的HARQ-ACK复用在一起，作为一个HARQ-ACK码本，且认为所述DCI中的末尾DCI中指示的PUCCH资源作为一个有效的PUCCH资源，且将所述HARQ-ACK码本在所述有效PUCCH资源中传输。这种方式能有效克服基站在当前DCI调度PDSCH时，不能预测后续是否还有DCI调度PDSCH的情况。
另外，所述参数也可以考虑采用前后DCI中所述参数的比特取值是否反转来表达对应的DCI是否为一个HARQ-ACK码本对应的PDSCH中末尾的PDSCH对应的DCI。例如，参数取值发生反转的DCI对应的PDSCH的HARQ-ACK为一个HARQ-ACK码本的末尾HARQ-ACK。如果直到所述上行单元中被指示的PUCCH资源处(这里是指，在上行单元中被指示的PUCCH资源之前N1+X时长处，其中N1+X至少包括：UE处理PDSCH，和形成对应HARQ-ACK的时间)，UE接收到的所述DCI中的参数取值均未发生反转，则使用接收的所述DCI中末尾DCI中指示的PUCCH资源作为一个有效的PUCCH资源，且将所述DCI对应的PDSCH的HARQ-ACK复用在一起，作为一个HARQ-ACK码本在该有效PUCCH资源中传输。这种方式能有效克服基站在当前DCI调度PDSCH时，不能预测后续是否还有DCI调度PDSCH的情况。
一个例子如图4所示，假设4个PDSCH被DCI调度，且DCI中携带有K1，PRI和所述参数取值，且这些K1指向相同的UL slot(如，第一个PDSCH在DL slot n，K1＝4，那么K1指向的slot为slot n+K1，k1的单位为slot；K1也可以是subslot等单位，此时就假设K1指向了相同的subslot，处理机制是相同的)，图4中在一个被指向的UL slot中有2个PUCCH资源，第一个PDSCH的DCI的PRI指向了该UL slot中的第一个PUCCH资源。此时第一个PDSCH的DCI中所述参数设置为0，即该DCI为一个HARQ-ACK码本对应的PDSCH中末尾的PDSCH对应的DCI。类似的第二个PDSCH的DCI中，K1＝3，PRI＝1，指向与第一个PDSCH对应的DCI指向的UL slot相同的UL slot，且所述参数置为1，此时就可以确认第二 个PDSCH对应的DCI为一个HARQ-ACK码本对应的PDSCH中末尾的PDSCH对应的DCI，且该DCI中指示的PUCCH资源为一个有效的PUCCH资源。这样，就将该DCI之前(包含当前)接收的DCI对应的PDSCH的HARQ-ACK复用在一起，作为一个HARQ-ACK码本，在这个有效的PUCCH资源中传输。也即是，第一个PDSCH和第二个PDSCH的HARQ-ACK复用在一起作为一个HARQ-ACK码本，并在第二个PDSCH的DCI指示的PUCCH资源中传输所述HARQ-ACK码本。第3个PDSCH对应的DCI中K1＝2，PRI＝0，此时所述参数设置为0，第4个PDSCH对应的DCI中K1＝1，PRI＝0，此时所述参数设置为1，这样，第四个PDSCH对应的DCI为一个HARQ-ACK码本对应的PDSCH中末尾的PDSCH对应的DCI，且该DCI中指示的PUCCH资源为一个有效的PUCCH资源，这样，第4个PDSCH对应DCI之前(包含)接收到DCI对应的PDSCH的HARQ-ACK复用在一起，作为一个HARQ-ACK码本，在该有效的PUCCH资源中传输。这个HARQ-ACK码本实际包含第3个PDSCH和第4个PDSCH的HARQ-ACK(为什么没有第1,2个PDSCH的HARQ-ACK，因为第1,2个PDSCH的HARQ-ACK作为一个HARQ-ACK已经在第2个PDSCH的DCI指示的有效PUCCH资源中传输了，也是前一次HARQ-ACK码本末尾DCI之后的DCI开始的，即第3个PDSCH的DCI直到当前DCI被选中)复用在一起，作为一个HARQ-ACK码本，并在第4个PDSCH的DCI指示的PUCCH资源传输。
还有一个特例，例如，如果第1，2，3，4的PDSCH的DCI中(假设K1均指向同一slot，如图4)，所述参数取值均为0，那么此时就以末尾DCI中的PRI指示的PUCCH资源作为有效PUCCH资源，且将接收到的所述DCI对应的PDSCH对应的HARQ-ACK复用在一起，在所述有效PUCCH资源中传输。另外，需要注意，末尾DCI调度的PDSCH满足一个条件，即末尾DCI调度的PDSCH需要一定的时间解码和形成对应的HARQ-ACK信息，假设这些需要N1+X时长，那么末尾DCI调度的PDSCH的末尾和末尾DCI中指示的PUCCH资源的开始之间至少间隔N1+X时长， 这样才能保证末尾DCI调度的PDSCH能被及时的解码并形成HARQ-ACK信息。N1+X可以根据UE的硬件能力确定出来。
具体实施例4：
具体实施例4类似具体实施例1，也是需要在物理层信令中引入一个参数，优选在DCI中增加这个参数，参数用来描述指示截止当前(包含)接收的DCI对应PDSCH的ACK/NACK为止，之前接收的DCI对应的PDSCH的ACK/NACK在一个HARQ-ACK码本中反馈。且当前DCI指示的PUCCH资源为一个有效的PUCCH资源。
相对于非有效的反馈HARQ-ACK的PUCCH资源，一个有效的反馈HARQ-ACK的PUCCH资源能够替换之前的非有效PUCCH资源，是被认为需要传输HARQ-ACK码本的PUCCH资源(或者说有效的PUCCH资源替换掉之前非有效的PUCCH资源，且把非有效的PUCCH资源计划发送的HARQ-ACK也在有效PUCCH资源中传输)。
如果接收的当前DCI中所述参数指示截止当前(包含)接收的DCI对应PDSCH的ACK/NACK为止，之前接收的DCI对应的PDSCH的ACK/NACK在一个HARQ-ACK码本中反馈，则将当前DCI之前(也包括当前DCI)接收的DCI调度的PDSCH的HARQ-ACK信息复用在一起，在当前DCI指示的有效的PUCCH资源中发送。注意，所述当前DCI之前，向前的截止位置是上一次的HARQ-ACK码本对应的末尾DCI之后开始的。
例如，参数为1bit开销，1bit为1表示为该DCI对应的PDSCH的HARQ-ACK是一个HARQ-ACK码本的末尾HARQ-ACK；1bit为0表示该DCI对应的PDSCH的HARQ-ACK不是一个HARQ-ACK码本的末尾HARQ-ACK。
另外，本方式包含下面的实施，如果直到所述上行单元中被指示的PUCCH资源处(这里是指，在上行单元中被指示的PUCCH资源之前N1+X时长处，其中N1+X至少包括：UE处理PDSCH，和形成对应HARQ-ACK的时间)，UE接收到的所述DCI中的参数取值均为0，则将接收的所述 DCI对应的PDSCH的HARQ-ACK复用在一起，作为一个HARQ-ACK码本，且认为所述DCI中的末尾DCI中指示的PUCCH资源作为一个有效的PUCCH资源，且将所述HARQ-ACK码本在所述有效PUCCH资源中传输。这种方式能有效克服基站在当前DCI调度PDSCH时，不能预测后续是否还有DCI调度PDSCH的情况。
另外，所述参数也可以考虑采用前后DCI中所述参数的比特取值是否反转来表达是否截止当前(包含)接收的DCI对应PDSCH的ACK/NACK为止，之前接收的DCI对应的PDSCH的ACK/NACK在一个HARQ-ACK码本中反馈。例如，参数取值发生反转的DCI为截止当前(包含)接收的DCI对应PDSCH的ACK/NACK为止，之前接收的DCI对应的PDSCH的ACK/NACK在一个HARQ-ACK码本中反馈。如果直到所述上行单元中被指示的PUCCH资源处(这里是指，在上行单元中被指示的PUCCH资源之前N1+X时长处，其中N1+X至少包括：UE处理PDSCH，和形成对应HARQ-ACK的时间)，UE接收到的所述DCI中的参数取值均未发生反转，则使用接收的所述DCI中末尾DCI中指示的PUCCH资源作为一个有效的PUCCH资源，且将所述DCI对应的PDSCH的HARQ-ACK复用在一起，作为一个HARQ-ACK码本在该有效PUCCH资源中传输。这种方式能有效克服基站在当前DCI调度PDSCH时，不能预测后续是否还有DCI调度PDSCH的情况。
一个例子如图4所示。假设4个PDSCH被DCI调度，且DCI中携带有K1，PRI和所述参数取值，且这些K1指向相同的UL slot(如，第一个PDSCH在DL slot n，K1＝4，那么K1指向的slot为slot n+K1，k1的单位为slot；K1也可以是subslot等单位，此时就假设K1指向了相同的subslot，处理机制是相同的)，图4中在一个被指向的UL slot中有2个PUCCH资源，第一个PDSCH的DCI的PRI指向了该UL slot中的第一个PUCCH资源。此时第一个PDSCH的DCI中所述参数设置为0，即截止当前(包含)接收的DCI对应PDSCH的ACK/NACK为止，之前接收的DCI对应的PDSCH的ACK/NACK在一个HARQ-ACK码本中反馈。类似的第二个 PDSCH的DCI中，K1＝3，PRI＝1，指向与第一个PDSCH对应的DCI指向的UL slot相同的UL slot，且所述参数置为1，此时就可以确认第二个PDSCH对应的DCI是截止当前(包含)接收的DCI对应PDSCH的ACK/NACK为止，之前接收的DCI对应的PDSCH的ACK/NACK在一个HARQ-ACK码本中反馈，且该DCI中指示的PUCCH资源为一个有效的PUCCH资源。这样，就将该DCI之前(包含当前)接收的DCI对应的PDSCH的HARQ-ACK复用在一起，作为一个HARQ-ACK码本，在这个有效的PUCCH资源中传输。也即是，第一个PDSCH和第二个PDSCH的HARQ-ACK复用在一起作为一个HARQ-ACK码本，并在第二个PDSCH的DCI指示的PUCCH资源中传输所述HARQ-ACK码本。第3个PDSCH对应的DCI中K1＝2，PRI＝0，此时所述参数设置为0，第4个PDSCH对应的DCI中K1＝1，PRI＝0，此时所述参数设置为1，这样，第四个PDSCH对应的DCI是截止当前(包含)接收的DCI对应PDSCH的ACK/NACK为止，之前接收的DCI对应的PDSCH的ACK/NACK在一个HARQ-ACK码本中反馈，且该DCI中指示的PUCCH资源为一个有效的PUCCH资源，这样，第4个PDSCH对应DCI之前(包含)接收到DCI对应的PDSCH的HARQ-ACK复用在一起，作为一个HARQ-ACK码本，在该有效的PUCCH资源中传输。这个HARQ-ACK码本实际包含第3个PDSCH和第4个PDSCH的HARQ-ACK(为什么没有第1,2个PDSCH的HARQ-ACK，因为第1,2个PDSCH的HARQ-ACK作为一个HARQ-ACK已经在第2个PDSCH的DCI指示的有效PUCCH资源中传输了，也是前一次HARQ-ACK码本末尾DCI之后的DCI开始的，即第3个PDSCH的DCI直到当前DCI被选中)复用在一起，作为一个HARQ-ACK码本，并在第4个PDSCH的DCI指示的PUCCH资源传输。
还有一个特例，例如，如果第1，2，3，4的PDSCH的DCI中(假设K1均指向同一slot，如图4)，所述参数取值均为0，那么此时就以末尾DCI中的PRI指示的PUCCH资源作为有效PUCCH资源，且将接收到的所述DCI对应的PDSCH对应的HARQ-ACK复用在一起，在所述有效 PUCCH资源中传输。另外，需要注意，末尾DCI调度的PDSCH满足一个条件，即末尾DCI调度的PDSCH需要一定的时间解码和形成对应的HARQ-ACK信息，假设这些需要N1+X时长，那么末尾DCI调度的PDSCH的末尾和末尾DCI中指示的PUCCH资源的开始之间至少间隔N1+X时长，这样才能保证末尾DCI调度的PDSCH能被及时的解码并形成HARQ-ACK信息。N1+X可以根据UE的硬件能力确定出来。
具体实施例5：
相对于上述的具体实施例1～4，本实施例中使用免开销的方式来隐含通知具体实施例1～4中所述参数取值为1或0时对应的情况。采用在DCI中使用不同的约定的CRC检验来分别表示上述实施例1～4中所述参数取值为1或0。例如，约定CRC_1和CRC_2，当DCI被基站使用CRC_1进行检验时，则表示上述实施例1～4中所述参数取值为1的情况，当DCI被基站使用CRC_2进行校验时，则表示上述实施例1～4中所述参数取值为0的情况。CRC_1对应的CRC校验比特生成多项式为第一种方式，CRC_2对应的CRC校验比特生成多项式为第二种方式。
这样也就是，在一个或多个DCI中指示了相同的上行单元来反馈所述DCI调度的PDSCH的HARQ-ACK信息时，在所述DCI中如果检测到CRC_1校验时，则表示上述实施例1～4中所述参数取值为1的情况，当所述DCI中检测到CRC_2检验时，则表示上述实施例1～4中所述参数取值为0的情况。对应的，也采用与实施例1～4中所述参数取值1或0后续相同的处理规则。
具体实施例5的方案可以避免信令开销，但是略微增加了UE的检测复杂度。
本实施例中，在一个或多个DCI中指示了相同的上行单元来反馈所述DCI调度的PDSCH的HARQ-ACK信息时，在所述DCI中如果检测到CRC_1校验时，则表示该DCI指示的PUCCH资源为一个有效的PUCCH资源。当所述DCI中检测到CRC_2检验时，则表示该DCI指示的PUCCH 资源是非有效的PUCCH资源。
相对于非有效的反馈HARQ-ACK的PUCCH资源，一个有效的反馈HARQ-ACK的PUCCH资源能够替换之前的非有效PUCCH资源，是被认为需要传输HARQ-ACK码本的PUCCH资源(或者说有效的PUCCH资源替换掉之前非有效的PUCCH资源，且把非有效的PUCCH资源计划发送的HARQ-ACK也在有效PUCCH资源中传输)。
如果接收的当前DCI指示的PUCCH资源被标记为有效的PUCCH资源，则将当前DCI之前(也包括当前DCI)接收的DCI对应的(也是调度的)PDSCH的HARQ-ACK信息复用在一起，作为一个HARQ-ACK码本，在当前DCI指示的PUCCH资源中发送。注意，所述当前DCI之前，向前的截止位置是上一次的HARQ-ACK码本对应的末尾DCI之后开始的。
如果直到所述上行单元中被指示的PUCCH资源处(这里是指，在上行单元中被指示的PUCCH资源之前N1+X时长处，其中N1+X至少包括：UE处理PDSCH，和形成对应HARQ-ACK的时间)，UE接收到的所述DCI均采用CRC_2校验，则使用接收的所述DCI中末尾DCI中指示的PUCCH资源作为一个有效的PUCCH资源，且将所述DCI对应的PDSCH的HARQ-ACK复用在一起，作为一个HARQ-ACK码本在该有效PUCCH资源中传输。这种方式能有效克服基站在当前DCI调度PDSCH时，不能预测后续是否还有DCI调度PDSCH的情况。
另外，本实施例中也可以考虑采用前后DCI中校验的CRC是否变化来表达对应的DCI指示的PUCCH资源是否为一个有效的PUCCH资源。例如，当前DCI采用的CRC相对于前一个DCI采用的CRC发生变化，则当前DCI中指示的PUCCH资源为一个有效的反馈HARQ-ACK的PUCCH资源。如果直到所述上行单元中被指示的PUCCH资源处(这里是指，在上行单元中被指示的PUCCH资源之前N1+X时长处，其中N1+X至少包括：UE处理PDSCH，和形成对应HARQ-ACK的时间)，UE接收到的所述DCI中的CRC均未发生变化，则使用接收的所述DCI中末尾 DCI中指示的PUCCH资源作为一个有效的PUCCH资源，且将所述DCI对应的PDSCH的HARQ-ACK复用在一起，作为一个HARQ-ACK码本在该有效PUCCH资源中传输。这种方式能有效克服基站在当前DCI调度PDSCH时，不能预测后续是否还有DCI调度PDSCH的情况。
一个例子如图5所示，图5是根据本申请另一个实施例的具体实施例5的示意图，如图5所示，假设4个PDSCH被DCI调度，且DCI中携带有K1，PRI和CRC校验，且这些K1指向相同的UL slot(如，第一个PDSCH在DL slot n，K1＝4，那么K1指向的slot为slot n+K1，k1的单位为slot；K1也可以是subslot等单位，此时就假设K1指向了相同的subslot，处理机制是相同的)，图5中在一个被指向的UL slot中有2个PUCCH资源，第一个PDSCH的DCI的PRI指向了该UL slot中的第一个PUCCH资源。此时第一个PDSCH的DCI中采用CRC_2校验，即该DCI中PRI指示的PUCCH资源为非有效PUCCH资源。类似的第二个PDSCH的DCI中，K1＝3，PRI＝1，指向与第一个PDSCH对应的DCI指向的UL slot相同的UL slot，且采用CRC_1校验，此时就可以确认第二个PDSCH对应的DCI指示的PUCCH资源为一个有效的PUCCH资源。这样，就将该DCI之前(包含当前)接收的DCI对应的PDSCH的HARQ-ACK复用在一起，作为一个HARQ-ACK码本，在这个有效的PUCCH资源中传输。也即是，第一个PDSCH和第二个PDSCH的HARQ-ACK复用在一起作为一个HARQ-ACK码本，并在第二个PDSCH的DCI指示的PUCCH资源中传输所述HARQ-ACK码本。第3个PDSCH对应的DCI中K1＝2，PRI＝0，此时采用CRC_2校验，第四个PDSCH对应的DCI中K1＝1，PRI＝0，此时采用CRC_1校验，这样，第四个PDSCH的DCI中指示了一个有效的PUCCH资源，这样，第4个PDSCH对应DCI之前(包含)接收到DCI对应的PDSCH的HARQ-ACK复用在一起，作为一个HARQ-ACK码本，在该有效的PUCCH资源中传输。这个HARQ-ACK码本实际包含第3个PDSCH和第4个PDSCH的HARQ-ACK(为什么没有第1,2个PDSCH的HARQ-ACK，因为第1,2个PDSCH的HARQ-ACK作为一个HARQ-ACK 已经在第2个PDSCH的DCI指示的有效PUCCH资源中传输了，也是前一次HARQ-ACK码本末尾DCI之后的DCI开始的，即第3个PDSCH的DCI直到当前DCI被选中)复用在一起，作为一个HARQ-ACK码本，并在第4个PDSCH的DCI指示的PUCCH资源传输。
还有一个特例，例如，如果第1，2，3，4的PDSCH的DCI中(假设K1均指向同一slot，如图4)，且均采用CRC_2校验，那么此时就以末尾DCI中的PRI指示的PUCCH资源作为有效PUCCH资源，且将接收到的所述DCI对应的PDSCH对应的HARQ-ACK复用在一起，作为一个HARQ-ACK码本，在所述有效PUCCH资源中传输。另外，需要注意，末尾DCI调度的PDSCH满足一个条件，即末尾DCI调度的PDSCH需要一定的时间解码和形成对应的HARQ-ACK信息，假设这些需要N1+X时长，那么末尾DCI调度的PDSCH的末尾和末尾DCI中指示的PUCCH资源的开始之间至少间隔N1+X时长，这样才能保证末尾DCI调度的PDSCH能被及时的解码并形成HARQ-ACK信息。N1+X可以根据UE的硬件能力确定出来。
具体实施例6：
具体实施例6相对于上述的实施例1～4，本实施例中使用免开销的方式来隐含通知实施例1～4中所述参数取值为1或0时对应的情况。采用在DCI中使用不同的约定的RNTI加扰来分别表示上述实施例1～4中所述参数取值为1或0。例如，约定RNTI_1和RNTI_2，当DCI被基站使用RNTI_1进行加扰时，则表示上述实施例1～4中所述参数取值为1的情况，当DCI被基站使用RNTI_2进行加扰时，则表示上述实施例1～4中所述参数取值为0的情况。
这样，也就是，在一个或多个DCI中指示了相同的上行单元来反馈所述DCI调度的PDSCH的HARQ-ACK信息时，在所述DCI中如果检测到RNTI_1加扰时，则表示上述实施例1～4中所述参数取值为1的情况，当所述DCI中检测到RNTI_2加扰时，则表示上述实施例1～4中所述参数取 值为0的情况。对应的，也采用与实施例1～4中所述参数取值1或0后续相同的处理规则。
具体实施例6的方式可以避免信令开销，但是略微增加了UE的检测复杂度。
本实施例中，在一个或多个DCI中指示了相同的上行单元来反馈所述DCI调度的PDSCH的HARQ-ACK信息时，在所述DCI中如果检测到RNTI_1加扰时，则表示该DCI指示的PUCCH资源为一个有效的PUCCH资源。当所述DCI中检测到RNTI_2加扰时，则表示该DCI指示的PUCCH资源是非有效的PUCCH资源。
相对于非有效的反馈HARQ-ACK的PUCCH资源，一个有效的反馈HARQ-ACK的PUCCH资源能够替换之前的非有效PUCCH资源，是被认为需要传输HARQ-ACK码本的PUCCH资源(或者说有效的PUCCH资源替换掉之前非有效的PUCCH资源，且把非有效的PUCCH资源计划发送的HARQ-ACK也在有效PUCCH资源中传输)。
如果接收的当前DCI指示的PUCCH资源被标记为有效的PUCCH资源，则将当前DCI之前(也包括当前DCI)接收的DCI对应的(也是调度的)PDSCH的HARQ-ACK信息复用在一起，作为一个HARQ-ACK码本，在当前DCI指示的PUCCH资源中发送。注意，所述当前DCI之前，向前的截止位置是上一次的HARQ-ACK码本对应的末尾DCI之后开始的。
如果直到所述上行单元中被指示的PUCCH资源处(这里是指，在上行单元中被指示的PUCCH资源之前N1+X时长处，其中N1+X至少包括：UE处理PDSCH，和形成对应HARQ-ACK的时间)，UE接收到的所述DCI均采用RNTI_2加扰，则使用接收的所述DCI中末尾DCI中指示的PUCCH资源作为一个有效的PUCCH资源，且将所述DCI对应的PDSCH的HARQ-ACK复用在一起，作为一个HARQ-ACK码本在该有效PUCCH资源中传输。这种方式能有效克服基站在当前DCI调度PDSCH时，不能预测后续是否还有DCI调度PDSCH的情况。
另外，本实施例中也可以考虑采用前后DCI中加扰的RNTI是否变化来表达对应的DCI指示的PUCCH资源是否为一个有效的PUCCH资源。例如，当前DCI采用的RNTI相对于前一个DCI采用的RNTI发生变化，则当前DCI中指示的PUCCH资源为一个有效的反馈HARQ-ACK的PUCCH资源。如果直到所述上行单元中被指示的PUCCH资源处(这里是指，在上行单元中被指示的PUCCH资源之前N1+X时长处，其中N1+X至少包括：UE处理PDSCH，和形成对应HARQ-ACK的时间)，UE接收到的所述DCI中的RNTI均未发生变化，则使用接收的所述DCI中末尾DCI中指示的PUCCH资源作为一个有效的PUCCH资源，且将所述DCI对应的PDSCH的HARQ-ACK复用在一起，作为一个HARQ-ACK码本在该有效PUCCH资源中传输。这种方式能有效克服基站在当前DCI调度PDSCH时，不能预测后续是否还有DCI调度PDSCH的情况。
一个例子如下，图6是根据本申请另一个实施例的具体实施例6的示意图，如图6所示，假设4个PDSCH被DCI调度，且DCI中携带有K1，PRI和RNTI加扰，且这些K1指向相同的UL slot(如，第一个PDSCH在DL slot n，K1＝4，那么K1指向的slot为slot n+K1，k1的单位为slot；K1也可以是subslot等单位，此时就假设K1指向了相同的subslot，处理机制是相同的)，图6中在一个被指向的UL slot中有2个PUCCH资源，第一个PDSCH的DCI的PRI指向了该UL slot中的第一个PUCCH资源。此时第一个PDSCH的DCI中采用RNTI_2加扰，即该DCI中PRI指示的PUCCH资源为非有效PUCCH资源。类似的第二个PDSCH的DCI中，K1＝3，PRI＝1，指向与第一个PDSCH对应的DCI指向的UL slot相同的UL slot，且采用RNTI_1加扰，此时就可以确认第二个PDSCH对应的DCI指示的PUCCH资源为一个有效的PUCCH资源。这样，就将该DCI之前(包含当前)接收的DCI对应的PDSCH的HARQ-ACK复用在一起，作为一个HARQ-ACK码本，在这个有效的PUCCH资源中传输。也即是，第一个PDSCH和第二个PDSCH的HARQ-ACK复用在一起作为一个HARQ-ACK码本，并在第二个PDSCH的DCI指示的PUCCH资源中传 输所述HARQ-ACK码本。第3个PDSCH对应的DCI中K1＝2，PRI＝0，此时采用RNTI_2加扰，第四个PDSCH对应的DCI中K1＝1，PRI＝0，此时采用CRC_1加扰，这样，第四个PDSCH的DCI中指示了一个有效的PUCCH资源，这样，第4个PDSCH对应DCI之前(包含)接收到DCI对应的PDSCH的HARQ-ACK复用在一起，作为一个HARQ-ACK码本，在该有效的PUCCH资源中传输。这个HARQ-ACK码本实际包含第3个PDSCH和第4个PDSCH的HARQ-ACK(为什么没有第1,2个PDSCH的HARQ-ACK，因为第1,2个PDSCH的HARQ-ACK作为一个HARQ-ACK已经在第2个PDSCH的DCI指示的有效PUCCH资源中传输了，也是前一次HARQ-ACK码本末尾DCI之后的DCI开始的，即第3个PDSCH的DCI直到当前DCI被选中)复用在一起，作为一个HARQ-ACK码本，并在第4个PDSCH的DCI指示的PUCCH资源传输。
还有一个特例，例如，如果第1，2，3，4的PDSCH的DCI中(假设K1均指向同一slot，如图4)，且均采用RNTI_2加扰，那么此时就以末尾DCI中的PRI指示的PUCCH资源作为有效PUCCH资源，且将接收到的所述DCI对应的PDSCH对应的HARQ-ACK复用在一起，作为一个HARQ-ACK码本，在所述有效PUCCH资源中传输。另外，需要注意，末尾DCI调度的PDSCH满足一个条件，即末尾DCI调度的PDSCH需要一定的时间解码和形成对应的HARQ-ACK信息，假设这些需要N1+X时长，那么末尾DCI调度的PDSCH的末尾和末尾DCI中指示的PUCCH资源的开始之间至少间隔N1+X时长，这样才能保证末尾DCI调度的PDSCH能被及时的解码并形成HARQ-ACK信息。N1+X可以根据UE的硬件能力确定出来。
具体实施例7：
具体实施例7的方案相对于上述的实施例1～4，本实施例中使用复用其他参数的方式来隐含通知实施例1～4中所述参数取值为1或0时对应的情况。复用相关技术的PRI参数，且为它增加新的含义。PRI在相关技术 的含义是指示一个PUCCH资源(这个PUCCH可能不是一个有效PUCCH资源)，这里额外的，再利用多个PRI取值相同时，末尾的PRI指示的PUCCH资源是一个有效PUCCH资源。
在一个或多个DCI中指示了相同的上行单元来反馈所述DCI调度的PDSCH的HARQ-ACK信息时，将所述DCI中包含相同PRI值的DCI的对应PDSCH的HARQ-ACK复用在一起，作为一个HARQ-ACK码本，且在具有相同PRI值的DCI中末尾DCI中PRI指示的PUCCH中传输所述HARQ-ACK码本。即具有相同PRI值的DCI中末尾DCI中PRI指示的PUCCH资源为一个有效的PUCCH资源。
注意：根据相关技术，根据待传输的UCI比特数确定对应的PUCCH集合，然后再根据PRI是指示从确定的PUCCH集合中选择被PRI指示的PUCCH资源。UE可以有最多4个PUCCH集合，每个PUCCH集合对应着传输给定比特数范围的UCI，例如，UE有2个PUCCH集合，PUCCH集合0中的PUCCH资源只能传输1～2bit的UCI，PUCCH集合1中的PUCCH资源只能传输大于2bit的UCI。所以，有时相同的PRI值，实际只是的PUCCH资源来自不同的PUCCH集合，是不同的PUCCH资源。
也就是说，如果基站需要将多个PDSCH的HARQ-ACK复用在一起，作为一个HARQ-ACK码本，且在一个PUCCH资源中传输，那么基站就在所述多个PDSCH的DCI中设置PRI具有相同的取值，与UE约定，使用所述多个PDSCH的DCI中末尾DCI中的PRI指示的PUCCH资源传输所述HARQ-ACK码本。
一个例子如图7所示，图7是根据本申请另一个实施例的具体实施例7的示意图，如图7所示，在第1,2个PDSCH对应的DCI中基站设置对应的DCI中PRI均为0，第3,4个PDSCH对应的DCI中基站设置对应的DCI中PRI均为2。这样，PRI为0的两个PDSCH的HARQ-ACK复用在一起，作为一个HARQ-ACK码本，在第2个PDSCH对应的DCI中的PRI指示的PUCCH资源中传输。PRI为2的两个PDSCH的HARQ-ACK复用 在一起，作为一个HARQ-ACK码本，在第4个PDSCH对应的DCI中的PRI指示的PUCCH资源中传输。
还有一个特例，例如，如果第1，2，3，4的PDSCH的DCI中PRI取值均为相同值，那么此时就以末尾DCI中的PRI指示的PUCCH资源作为有效PUCCH资源，且将接收到的所述DCI对应的PDSCH对应的HARQ-ACK复用在一起，作为一个HARQ-ACK码本，在所述有效PUCCH资源中传输。另外，需要注意，末尾DCI调度的PDSCH满足一个条件，即末尾DCI调度的PDSCH需要一定的时间解码和形成对应的HARQ-ACK信息，假设这些需要N1+X时长，那么末尾DCI调度的PDSCH的末尾和末尾DCI中指示的PUCCH资源的开始之间至少间隔N1+X时长，这样才能保证末尾DCI调度的PDSCH能被及时的解码并形成HARQ-ACK信息。N1+X可以根据UE的硬件能力确定出来。
具体实施例8：
相对于上述的具体实施例1～4，本实施例中使用复用其他参数的方式来隐含通知实施例1～4中所述参数取值为1或0时对应的情况。复用相关技术的PRI参数，且为它增加新的含义。PRI在相关技术中有3bit开销，组成8种状态，约定其中一种状态表示实施例1～4中所述参数为0的含义，此时PRI指示的PUCCH资源无效，其余的状态表示实施例1～4中所述参数为1的含义，且PRI指示的PUCCH资源为有效的。例如PRI取值中约定“000”表示所述实施例1～4中所述参数为0的含义，其余取值均表示所述实施例1～4中所述参数为1的含义。其余的操作与实施例1～4所述参数取值为1或0的操作相同。下面以实施例1为例进行复述，其余的实施例不再赘述。
在一个或多个DCI中指示了相同的上行单元来反馈所述DCI调度的PDSCH的HARQ-ACK信息时，利用所述DCI中的PRI参数指示那个DCI中指示的PUCCH资源为一个有效的PUCCH资源。如，假设使用“000”表示上述方式1～4中参数取值为0情况，其他状态表达上述方式1～4中参 数取值为1的情况。
也就是说，如果基站需要将多个PDSCH的HARQ-ACK复用在一起作为一个HARQ-ACK码本，且在一个PUCCH资源中传输，那么基站就在所述多个PDSCH的DCI中末尾DCI中设置PRI取值非“000”为状态，来表示该DCI指示的PUCCH资源为一个有效的PUCCH资源，在所述多个PDSCH的DCI中非末尾DCI中设置PRI为“000”。
例如，当前DCI中所述PRI取值为“101”，则当前DCI中指示的PUCCH资源为一个有效的反馈HARQ-ACK的PUCCH资源。如果直到所述上行单元中被指示的PUCCH资源处(这里是指，在上行单元中被指示的PUCCH资源之前N1+X时长处，其中N1+X至少包括：UE处理PDSCH，和形成对应HARQ-ACK的时间)，UE接收到的所有DCI中的PRI取值都为“000”，则使用接收到的DCI中的末尾DCI中PRI指示的PUCCH资源为有效PUCCH资源(此时PRI取值“000”，但是指示的是有效PUCCH资源)。这种方式能有效克服基站在当前DCI调度PDSCH时，不能预测后续是否还有DCI调度PDSCH的情况。
采用上述方案，有效解决了打孔传输时的半静态码本的确定，且开销适中。
