Description

HARQ-ACK反馈时刻、位置的确定以及设备和介质
本申请要求申请日为2020/2/12的中国专利申请202010089136.X的优先权。本申请引用上述中国专利申请的全文。
技术领域
本发明属于5G(5th generation mobile networks，第五代移动通信技术)通信领域，尤其涉及一种HARQ-ACK(Hybrid Automatic Repeat request-ACK，混合自动重传请求-确认)反馈时刻、位置的确定以及设备和介质。
背景技术
在5G NR(New Radio，新空口)中，PDSCH(Physical Downlink Shared Channel，物理下行共享信道)用于传输下行数据，PDCCH(Physical Downlink Control Channel，物理下行控制信道)用于传输DCI(Downlink Control Information,下行控制信息)。此前，NR规定一个DCI仅调度一个小区的PDSCH，在确定PDSCH对应的HARQ-ACK反馈的时刻时，如图1所示：
K0，K1单位都是时隙(slot)，K0表示PDSCH与PDCCH的时间间隔。K1表示HARQ-ACK反馈与PDSCH的时间间隔。PDSCH对应的HARQ-ACK反馈的时刻即为PDSCH的结束时刻加K1。
如今，NR决定支持一个DCI调度至多两个小区的PDSCH，如何在此情况下确定HARQ-ACK反馈的时刻成为现阶段亟需解决的问题。
另外，NR动态HARQ-ACK码本的确定基于计数DAI(counter DAI，Downlink Assignment Indicater，下行分配指示)和总DAI(total DAI)。对于某一个PUCCH(Physical Uplink Control Channel，物理上行链路控制信道)，NR中总DAI为物理下行控制信道监听时刻集合内从第一个DAI时刻至当前DAI时刻，在所有小区，基站发送的DCI的总数量。计数DAI为物理下行控制信道监听时刻集合内，基站在当前DAI时刻发送的从第一个小区至当前小区DCI次数的累加计数，与前一DAI时刻对应的总DAI之和。
计数DAI在同一DAI时刻按照小区编号从小到大进行计数。
在DCI中的指示如下表的例子所示，配置了6个小区(cell)，在三个PDCCH监听时刻(occasion)所监听得到的PDCCH内计数DAI及总DAI数值如下表所示：
Figure PCTCN2021075646-appb-000001
Figure PCTCN2021075646-appb-000002
上述计算计数DA和总DAI的方法也仅能在一个DCI调度一个小区的PDSCH时实现，如何在一个DCI调度超过一个小区的PDSCH的情况下确定计算计数DAI和总DAI，进而确定HARQ-ACK位置也是现阶段亟需解决的问题。

实施例1
本实施例提供一种确定HARQ-ACK反馈时刻的方法。所述方法包括：
当DCI调度多于一个小区的PDSCH时，以被调度的小区中的1个小区的PDSCH的结束时刻所在时隙为参考时隙，计算HARQ-ACK反馈的时刻所在时隙：
HARQ-ACK反馈的时刻所在时隙＝n+k
上式中，n为所述参考时隙，k为DCI中指示的HARQ-ACK反馈与所述参考时隙之间的时隙偏差。
本实施例中，DCI调度小区的总数优选为2。
本实施例的第一种情况中，所述参考时隙可以为被调度的小区中，服务小区ID(serving cell ID)最小的小区的PDSCH的结束时刻所在时隙。下面给一实例对上述方法做进一步说明：
如图2所示，基站在slot n在PDCCH中传输DCI，DCI调度2个小区(cell1,cell2)的PDSCH(PDSCH1,PDSCH2)，假设DCI中指示ARQ-ACK反馈与PDSCH的时隙偏差k1＝2且PUCCH的子载波间隔与cell 1相同：
若cell 1的serving cell ID＝245，cell 2的serving cell ID＝345，则以PDSCH1的结束时刻所在时隙slot n+1为参考时隙，由此计算出HARQ-ACK反馈的时刻所在时隙为slot n+3，即用户设备在以PUCCH子载波间隔为粒度的slot n+3内进行HARQ-ACK反馈。
在本实施例的第二种情况中，考虑到载波指示标识(Carrier indicator flag，缩写为CIF)较小的小区通常是较重要的辅载波，由此所述参考时隙可以为被调度的小区中，具有的载波指示标识最小的小区的PDSCH的结束时刻所在时隙。下面给一实例对上述方法做进一步说明：
同样如图2所示，基站在slot n在PDCCH中传输DCI，DCI调度2个小区(cell1,cell2)的PDSCH(PDSCH1,PDSCH2)，假设DCI中指示ARQ-ACK反馈与PDSCH的时 隙偏差k1＝2且PUCCH的子载波间隔与cell 1相同：
若cell 1的CIF＝0，cell 2的CIF＝3，则以PDSCH1的结束时刻所在时隙slot n+1为参考时隙，由此计算出HARQ-ACK反馈的时刻所在时隙为slot n+3，即用户设备在以PUCCH子载波间隔为粒度的slot n+3内进行HARQ-ACK反馈。
在本实施例的第三种情况中，所述参考时隙可以为被调度的小区中，被高层信令配置为参考小区的PDSCH的结束时刻所在时隙。其中的高层信令可以包括RRC(Radio Resource Control，无线资源控制)信令。下面给一实例对上述方法做进一步说明：
同样如图2所示，基站在slot n在PDCCH中传输DCI，DCI调度2个小区(cell1,cell2)的PDSCH(PDSCH1,PDSCH2)，假设DCI中指示ARQ-ACK反馈与参考时隙的时隙偏差k1＝2且PUCCH的子载波间隔与cell 1相同：
若高层信令配置cell 1与cell2一起进行多小区调度时，cell 1为参考小区，则以cell1的PDSCH的结束时刻所在时隙slot n+1为参考时隙，由此计算出HARQ-ACK反馈的时刻所在时隙为slot n+3，即用户设备在以PUCCH子载波间隔为粒度的slot n+3内进行HARQ-ACK反馈。
在本实施例的第四种情况中，为了更容易确定反馈时刻、不会出现处理时间不足的问题，所述参考时隙可以为：在被调度的小区的PDSCH的结束时刻所在时隙不同时，最晚结束的PDSCH的结束时刻所在时隙，或，在被调度的小区的PDSCH的结束时刻所在时隙相同时，同时结束的PDSCH的结束时刻所在时隙。下面给一实例对上述方法做进一步说明：
基站在slot n在PDCCH中传输DCI，DCI调度2个小区(cell1,cell2)的PDSCH(PDSCH1,PDSCH2)，假设DCI中指示ARQ-ACK反馈与参考时隙的时隙偏差k1＝2且PUCCH的子载波间隔与cell 1相同：
若同样如图2所示，PDSCH1的结束位置晚于PDSCH2的结束位置，则以PDSCH1的结束时刻所在时隙slot n+1为参考时隙，由此计算出HARQ-ACK反馈的时刻所在时隙为slot n+3，即用户设备在以PUCCH子载波间隔为粒度的slot n+3内进行HARQ-ACK反馈；
若如图3所示，PDSCH2的结束位置晚于PDSCH1的结束位置，则以PDSCH2的结束时刻所在时隙slot n+2为参考时隙，由此计算出HARQ-ACK反馈的时刻所在时隙为slot n+4，即用户设备在以PUCCH子载波间隔为粒度的slot n+4内进行HARQ-ACK反馈；
若如图4所示，PDSCH1的结束位置与PDSCH2的结束位置相同，均结束于slot n+1， 则以slot n+1为参考时隙，由此计算出HARQ-ACK反馈的时刻所在时隙为slot n+3，即用户设备在以PUCCH子载波间隔为粒度的slot n+3内进行HARQ-ACK反馈。
本实施例的方法弥补了现有技术在一个DCI调度多于一个小区的PDSCH时无法确定HARQ-ACK反馈的时刻的不足，可以支持一个PUCCH同时反馈一个DCI调度多于一个PDSCH所对应的HARQ-ACK。
实施例2
本实施例提供一种确定HARQ-ACK反馈时刻的方法。所述方法包括：
当DCI调度多于一个小区的PDSCH时，分别计算每个小区的PDSCH对应的HARQ-ACK反馈的时刻所在时隙：
HARQ-ACK反馈的时刻所在时隙＝n i+k
上式中，n i为对应的第i个小区的PSDSCH的结束时刻所在时隙，k为DCI中指示的ARQ-ACK反馈与对应的PDSCH的结束时刻所在时隙之间的时隙偏差。其中，i为正整数且不超过DCI调度小区的总数。
本实施例中，DCI调度小区的总数优选为2。
下面给一实例对上述方法做进一步说明：
基站在slot n在PDCCH中传输DCI，DCI调度2个小区(cell1,cell2)的PDSCH(PDSCH1,PDSCH2)，假设DCI中指示ARQ-ACK反馈与PDCCH的时隙偏差k1＝2且PUCCH的子载波间隔与cell 1相同：
若如图5所示，PDSCH1的结束时刻所在时隙为slot n+1，PDSCH2的结束时刻所在时隙为slot n+2，则PDSCH1对应的HARQ-ACK反馈的时刻所在时隙为slot n+3，PDSCH2对应的HARQ-ACK反馈的时刻所在时隙为slot n+4，即用户设备在以PUCCH1子载波间隔为粒度的slot n+3内进行PDSCH1对应的HARQ-ACK反馈，在以PUCCH2子载波间隔为粒度的slot n+4内进行PDSCH2对应的HARQ-ACK反馈。
本发明弥补了现有技术在一个DCI调度多于一个小区的PDSCH时无法确定HARQ-ACK反馈的时刻的不足，可以支持一个PUCCH同时反馈一个DCI调度多于一个PDSCH所对应的HARQ-ACK。
实施例3
本实施例提供一种在动态码本内确定HARQ-ACK位置的方法。所述方法包括：
当DCI调度至少一个小区的PDSCH时，计算计数DAI和总DAI：
计数DAI＝当前DCI的前一次DCI中的计数DAI+调度小区的总数
总DAI＝当前DCI的前一次DCI中的总DAI+调度小区的总数。
其中，若DCI调度一个小区的PDSCH，则：
计数DAI＝当前DCI的前一次DCI中的计数DAI+1；
总DAI＝当前DCI的前一次DCI中的总DAI+1；
所述方法还包括将所述小区的PDSCH对应的HARQ-ACK放在所述计数DAI的DAI计数的位置。
若DCI调度多于一个小区的PDSCH，则所述方法还包括：
将被调度的小区按照预设规则排序，将排序后小区的PDSCH对应的HARQ-ACK相应放在所述计数DAI的第一个到最后一个DAI计数的位置。
其中，所述预设规则可以包括：
按照小区的服务小区ID由小到大排序；
或，按照小区具有的载波指示标识由小到大排序；
或，按照被高层指令配置的参考小区优先的规则排序(即被高层指令配置为参考小区的排在最前面)。
本实施例中，被调度的小区的CBG(码块组)配置相同。
本实施例中，DCI调度小区的总数优选为2。以此为例，当DCI调度2个小区的PDSCH时，其中被调度的2个小区的CBG配置相同，则：
计数DAI＝当前DCI的前一次DCI中的计数DAI+2；
总DAI＝当前DCI的前一次DCI中的总DAI+2；
将被调度的小区按照预设规则排序，将排序后小区的PDSCH对应的HARQ-ACK相应放在所述计数DAI的第一个到最后一个DAI计数的位置，具体可以包括以下步骤中的任意一种：
第一种，对应于按照小区的服务小区ID由小到大排序的预设规则：将所述2个小区中服务小区ID最小的PDSCH对应的HARQ-ACK放在所述计数DAI的第一个DAI计数的位置，服务小区ID最大的PDSCH对应的HARQ-ACK放在所述计数DAI的第二个DAI计数的位置；
第二种，对应于按照小区具有的载波指示标识由小到大排序的预设规则：将所述2个小区中具有的载波指示标识最小的小区的PDSCH对应的HARQ-ACK放在所述计数DAI的第一个DAI计数的位置，具有的载波指示标识最大的小区的PDSCH对应的HARQ-ACK放在所述计数DAI的第二个DAI计数的位置；
第三种，对应于按照被高层指令配置的参考小区优先的规则排序的预设规则：将所述2个小区中被高层信令配置为参考小区的PDSCH对应的HARQ-ACK放在所述计数 DAI的第一个DAI计数的位置，未被所述高层信令配置为参考小区的PDSCH对应的HARQ-ACK放在所述计数DAI的第二个DAI计数的位置，其中的高层信令可以包括RRC信令。
下面给一实例对上述方法做进一步说明：
在载波聚合的情况下实际DAI如下表所示，而非DCI中的指示(在实际值的基础上模4)。其中表中加(2)的DAI表示此DCI是调度2个小区的PDSCH，这两个小区的serving cell ID分别为234和345，这两个小区的CIF分别为0和3：
Figure PCTCN2021075646-appb-000003
针对上表，若采用上述的第一种步骤确定两个小区的PDSCH对应的HARQ-ACK的位置，则：
Occasion0内cell 1 PDSCH对应的HARQ-ACK放在计数DAI(＝1)的第一个DAI计数的位置，即第一HARQ-ACK位置，cell 2 PDSCH对应的HARQ-ACK放在计数DAI(＝2)的第二个DAI计数的位置，即第二HARQ-ACK位置。Occasion1内cell 1 PDSCH对应的HARQ-ACK放在计数DAI(＝7)的第一个DAI计数的位置，即第七HARQ-ACK位置，cell 2 PDSCH对应的HARQ-ACK放在计数DAI(＝8)的第二个DAI计数的位置，即第八HARQ-ACK位置。
同样针对上表，若采用上述的第二种步骤确定两个小区的PDSCH对应的HARQ-ACK的位置，则：
Occasion0内cell 1 PDSCH对应的HARQ-ACK放在计数DAI(＝1)的第一个DAI计数的位置，即第一HARQ-ACK位置，cell 2 PDSCH对应的HARQ-ACK放在计数DAI(＝2)的第二个DAI计数的位置，即第二HARQ-ACK位置。Occasion1内cell 1 PDSCH对应的HARQ-ACK放在计数DAI(＝7)的第一个DAI计数的位置，即第七HARQ-ACK位置，cell 2 PDSCH对应的HARQ-ACK放在计数DAI(＝8)的第二个DAI计数的位置，即第八HARQ-ACK位置。
同样针对上表，若采用上述的第三种步骤确定两个小区的PDSCH对应的HARQ- ACK的位置，则：
若高层信令配置cell1为参考小区，则：occasion0内cell 1 PDSCH对应的HARQ-ACK放在计数DAI(＝1)的第一个DAI计数的位置，即第一HARQ-ACK位置，cell 2PDSCH对应的HARQ-ACK放在计数DAI(＝2)的第二个DAI计数的位置，即第二HARQ-ACK位置。Occasion1内cell 1 PDSCH对应的HARQ-ACK放在计数DAI(＝7)的第一个DAI计数的位置，即第七HARQ-ACK位置，cell 2 PDSCH对应的HARQ-ACK放在计数DAI(＝8)的第二个DAI计数的位置，即第八HARQ-ACK位置。
相反，若高层信令配置cell2为参考小区，则：occasion0内cell 2 PDSCH对应的HARQ-ACK放在计数DAI(＝1)的第一个DAI计数的位置，即第一HARQ-ACK位置，cell 1 PDSCH对应的HARQ-ACK放在计数DAI(＝2)的第二个DAI计数的位置，即第二HARQ-ACK位置。Occasion1内cell 2 PDSCH对应的HARQ-ACK放在计数DAI(＝7)的第一个DAI计数的位置，即第七HARQ-ACK位置，cell 1 PDSCH对应的HARQ-ACK放在计数DAI(＝8)的第二个DAI计数的位置，即第八HARQ-ACK位置。
需要说明的是，上述第n HARQ-ACK位置可对应多个bit，如当没有配置CBG且支持2个码字且非HARQ-ACK bundle，一个HARQ-ACK位置有2bits。如当没有配置CBG且支持2个码字且HARQ-ACK bundle时，一个HARQ-ACK位置有1bits。如当配置CBG且支持2个码字且CBG＝8时，一个HARQ-ACK位置有8bits。
本实施例的方法提供了新的计数DAI和总DAI的计算方式，以及基于该计算方式的、在动态码本内确定HARQ-ACK位置的具体方案，尤其是在动态码本中反馈一个DCI调度两个小区的PDSCH所对应的HARQ-ACK位置的方案，具有简化高层信令配置、不需要额外动态信令交互的优点。
