背景技术
在第五代移动通信技术(5th-Generation,5G)新空口(New Radio,NR)中,支持使用跨时隙的调度方法,因此在一个物理下行控制信道(Physical Downlink Control Channel,PDCCH)检测机会中,可能会传输多于一个用于调度不同时隙或者同一时隙中不同长度的下行数据传输的PDCCH。如图1所示,在时隙0,时隙2,时隙4,时隙6的PDCCH检测机会中都传输了两个PDCCH,分别用于调度n+2和时隙n+3中的下行数据传输,其中,网格填充框表示PDCCH检测机会,斜线填充框表示相同反馈窗口中的物理下行共享信道(Physical Downlink Shared Channel,PDSCH),横线填充框表示混合自动重传应答信息(Hybrid Automatic Repeat request Acknowledgement,HARQ-ACK)反馈,虚线箭头表示PDCCH-PDSCH调度时序,实线箭头表示PDSCH-HARQ-ACK反馈时序。
目前在确定半静态反馈码本时,并没有考虑上述情况,可能会导致产生错误的半静态反馈码本。例如,在图1的例子中,在反馈窗口内的PDSCH对应有4个PDCCH检测机会,则在产生反馈码本时,如果未配置码块组(Code Block Group,CBG)和多码字传输,则对应产生4比特反馈信息,但是实际上每个PDCCH检测机会中传了两个PDCCH,调度了反馈窗口中的8个PDSCH传输,使用相关技术中的半静态码本方案会有4个PDSCH无反馈信息。
目前在确定半静态反馈码本时,并没有考虑在一个PDCCH检测机会中, 可能会传输多于一个用于调度不同时隙或者同一时隙中不同长度的下行数据传输的PDCCH的情况,可能会导致产生错误的半静态反馈码本,从而影响***传输性能。

具体实施方式
为使本公开的目的、技术方案和优点更加清楚,下面将结合附图及具体实施例对本公开进行详细描述。
首先对本公开实施例中所提到的一些概念进行说明如下。
目前在NR通信***中,支持HARQ-ACK反馈使用半静态码本方案。
在对用户配置使用半静态码本方案时,首先需要确定一个反馈窗口M,M定义为基于高层信令配置的最大和最小数据到反馈之间的时隙间隔,以及高层信令配置给用户设备(User Equipment,UE,也称终端)的多个数据到反馈之间的时隙间隔值,UE可以确定出M个用于下行控制信息(Downlink Control Information,DCI)格式1_0或者DCI格式1_1传输的PDCCH检测机会,对应在同一个物理上行控制信道(Physical Uplink Control Channel,PUCCH)或者物理上行共享信道(Physical Uplink Shared Channel,PUSCH)反馈HARQ-ACK。
在产生反馈码本时,按照先载波索引增加后PDCCH检测机会索引增加的顺序对每一个载波上的每一个PDCCH检测机会产生对应的反馈比特,具体过程如下:
如果载波被配置HARQ-ACK不使用空间合并,不使用基于CBG的HARQ-ACK反馈,且当前载波被配置了需要接收两个传输块,则对每一个传输块分别产生1比特的反馈信息,对当前载波当前PDCCH检测机会共产生2比特反馈信息;
如果载波被配置HARQ-ACK使用空间合并,不使用基于CBG的 HARQ-ACK反馈,且当前载波被配置了需要接收两个传输块,则对两个传输块的1比特的反馈信息进行逻辑与操作,对当前载波当前PDCCH检测机会共产生1比特的反馈信息,如果终端仅接收到一个传输块,假设第二个传输块对应的反馈信息为ACK;
如果载波被配置使用基于CBG的HARQ-ACK反馈,且当前载波被配置需要接收两个传输块,则对每一个传输块分别产生X比特的反馈信息,X为高层信令配置载波上使用的最大CBG个数,对当前载波当前PDCCH检测机会共产生2X比特反馈信息;
如果载波被配置使用基于CBG的HARQ-ACK反馈,且当前载波被配置需要接收一个传输块,则对当前载波当前PDCCH检测机会共产生X比特的反馈信息,X为高层信令配置载波上使用的最大CBG个数。
本公开针对相关技术中的半静态反馈码本确定方案,并没有考虑在一个PDCCH检测机会中,可能会传输多于一个用于调度不同时隙或者同一时隙中不同长度的下行数据传输的PDCCH的情况,导致产生的半静态反馈码本不准确,影响***传输性能的问题,提供一种反馈码本确定方法及装置。
如图2所示,本公开实施例的反馈码本确定方法,包括:
步骤21,获取一个载波的一个物理下行控制信道PDCCH检测机会中传输的第一PDCCH数量;
需要说明的是,该第一PDCCH数量指的是一个载波一个PDCCH检测机会中可以传输的最大PDCCH个数。
步骤22,根据所述第一PDCCH数量,确定一个载波的一个PDCCH检测机会的目标反馈信息的长度;
需要说明的是,该目标反馈信息的长度具体为目标反馈信息的比特位个数。
步骤23,根据所述目标反馈信息的长度,确定反馈码本信息。
在得到目标反馈信息的长度,进行反馈信息的确定,得到最终的反馈码本信息,需要说明的是,该反馈码本确定方法可以应用于终端,也可以应用于基站,即终端根据该反馈码本确定方法生成反馈码本信息,并发送给基站,而基站根据该反馈码本确定方法确定终端发送的反馈码本信息,并在对应位 置接收该反馈码本信息。
需要说明的是,步骤21可以采用如下方式中的一种方式实现:
方式一、将一个载波的一个PDCCH检测机会中配置的控制信息资源集合个数,确定为第一PDCCH数量;
方式二、将一个载波的一个PDCCH检测机会中全部控制信息资源集合中配置的用于传输需要进行混合自动重传应答信息(HARQ-ACK)反馈的PDCCH的搜索空间个数之和,确定为第一PDCCH数量;
方式三、将一个载波的一个PDCCH检测机会中全部控制信息资源集合中配置的需要进行HARQ-ACK反馈的搜索空间对应的PDCCH候选集合个数之和,确定为第一PDCCH数量;
需要说明的是,此种实现方式中所说的需要进行HARQ-ACK反馈的搜索空间对应的PDCCH是通过小区无线网络临时标识(C-RNTI)或半静态调度无线网络临时标识(SPS-RNTI)加扰的。
方式四、将一个载波的一个PDCCH检测机会中全部控制信息资源集合中包含的控制信道单元(CCE)个数之和,确定为第一PDCCH数量;
方式五、获取协议预定义的第一PDCCH数量;
需要说明的是,在此种方式下,第一PDCCH数量在通信协议标准预定义,终端或基站可以直接获取得到。
方式六、获取基站通过高层信令配置的第一PDCCH数量;
需要说明的是,在第一PDCCH数量由基站通过高层信令(例如为无线资源控制(RRC)信令)配置给终端时,该第一PDCCH数量为大于或等于1且小于或等于4的整数。
方式七、根据PDCCH检测机会周期,确定第一PDCCH数量。
具体地,该方式七可以采用如下方式中的一种方式实现:
方式A1、将PDCCH检测机会周期确定为第一PDCCH数量;
在此种实现方式下,第一PDCCH数量便等于PDCCH检测机会周期。例如,一个载波上的PDCCH检测机会周期为2个时隙,则说明每2个时隙中存在一个PDCCH检测机会,为了保证所有时隙中的下行传输都能够被调度,则令一个PDCCH检测机会中传输的第一PDCCH数量(即最大PDCCH个数) 为2。
方式A2、根据PDCCH检测机会周期和无线资源控制(RRC)配置的物理下行共享信道(PDSCH)资源分配信息,确定第一PDCCH数量;
在此种实现方式下,第一PDCCH数量由PDCCH检测机会周期和RRC配置PDSCH资源分配信息确定,较优地,第一PDCCH数量为PDCCH检测机会周期中可传输的最大时域上不重叠的PDSCH个数,例如检测机会周期为1个时隙,但是RRC配置的PDSCH资源分配信息中指示PDSCH传输的最小长度为7个正交频分复用(OFDM)符号,则一个时隙(需要说明的是,一个时隙包含14个OFDM符号)中最多传输两个PDSCH,则令一个PDCCH检测机会中传输的第一PDCCH数量为2。
进一步地,步骤22的具体实现方式为:
根据公式:N=A1×A2×A3,得到一个载波的一个PDCCH检测机会的目标反馈信息的长度;
其中,N为一个载波的一个PDCCH检测机会的目标反馈信息的长度;A1为一个载波的一个PDCCH检测机会中传输的第一PDCCH数量;A2为载波配置的传输块的数量;A3为载波配置的最大码块组CBG的数量。
进一步地,步骤23的具体实现方式为:
确定一个载波的一个PDCCH检测机会中每个PDCCH的反馈信息;
根据PDCCH的排序,将每个PDCCH的反馈信息按照所述目标反馈信息的长度进行级联,确定一个载波的一个PDCCH检测机会的反馈码本信息。
具体地,确定一个载波的一个PDCCH检测机会中每个PDCCH的反馈信息的实现方式包括下列实现方式中的一项:
方式B1、当载波没有配置基于CBG的HARQ-ACK反馈时,对每一个传输块确定一比特反馈信息,对每一个PDCCH,将至少一个传输块对应的反馈信息按照传输块的顺序进行级联得到PDCCH对应的反馈信息;
此种实现方式中,是根据一个PDCCH中的每个传输块的反馈信息确定得到此PDCCH对应的反馈信息,因每个传输块是按顺序划分的,所以在级联时,只需按照传输块的划分顺序一一将传输块对应的反馈信息进行级联便得到一个PDCCH对应的反馈信息。
方式B2、当载波配置了基于CBG的HARQ-ACK反馈时,将至少一个CBG对应的反馈信息,按照CBG的顺序进行级联得到传输块对应的反馈信息,对每一个PDCCH,将至少一个传输块对应的反馈信息按照传输块的顺序进行级联得到PDCCH对应的反馈信息;
在此种情况下,每个传输块中划分有多个CBG,因每个CBG是按顺序划分的,在进行级联时,按照CBG的划分顺序一一将CBG对应的反馈信息进行级联,得到每个传输块对应的反馈信息,然后再按照传输块的划分顺序一一将传输块对应的反馈信息进行级联便得到一个PDCCH对应的反馈信息。
方式B3、当载波配置了基于CBG的HARQ-ACK反馈时,对每一个CBG级联两个传输块对应的反馈信息,按照CBG的顺序将至少一个CBG对应的反馈信息进行级联得到PDCCH对应的反馈信息。
在此种情况下,每个传输块中划分有多个CBG,在进行级联时,将两个传输块对应的反馈信息中的对应位置的CBG对应的反馈信息进行级联,然后,在将级联完成后的CBG对应的反馈信息,按照CBG的划分顺序一一将级联完成后的CBG对应的反馈信息级联,得到一个PDCCH对应的反馈信息。
在得到每一个PDCCH对应的反馈信息后,便可以按照PDCCH的排序进行一个载波的一个PDCCH检测机会的反馈码本信息的确定,具体地,PDCCH的排序的确定方式可以采用以下方式中的一项:
方式C1、若第一PDCCH数量为一个载波的一个PDCCH检测机会中配置的控制信息资源集合个数,按照PDCCH对应的控制信息资源集合的标识信息,确定PDCCH的排序;
需要说明的是,若第一PDCCH数量为一个载波的一个PDCCH检测机会中配置的控制信息资源集合个数,每个控制信息资源集合中最多传输一个PDCCH,则根据控制信息资源集合的标识信息便可确定PDCCH的排序,具体地,该控制信息资源集合的标识信息可以为控制信息资源集合ID。
方式C2、若第一PDCCH数量为一个载波的一个PDCCH检测机会中至少一个控制信息资源集合中配置的用于传输需要进行HARQ-ACK反馈的PDCCH的搜索空间个数之和,根据PDCCH对应的控制信息资源集合的标识信息和搜索空间的标识信息,确定PDCCH的排序;
需要说明的是,若第一PDCCH数量为一个载波的一个PDCCH检测机会中至少一个控制信息资源集合中配置的用于传输需要进行HARQ-ACK反馈的PDCCH的搜索空间个数之和,每个搜索空间最多传输一个PDCCH,则根据PDCCH对应的控制信息资源集合的标识信息(例如为控制信息资源集合ID)和搜索空间的标识信息(例如为搜索空间ID)便可确定PDCCH的排序,例如,在每一个控制信息资源集合之内,按照PDCCH对应的不同搜索空间ID进行排序;然后对多个控制信息资源集合之内的PDCCH按照控制信息资源集合ID从小到大的顺序进行排序。
方式C3、若第一PDCCH数量为一个载波的一个PDCCH检测机会中至少一个控制信息资源集合中配置的需要进行HARQ-ACK反馈的搜索空间对应的PDCCH候选集合个数之和,根据PDCCH对应的控制信息资源集合的标识信息、搜索空间的标识信息和搜索空间中的PDCCH候选顺序,确定PDCCH的排序;
例如,在每一个搜索空间之内,按照搜索空间中的PDCCH候选顺序确定PDCCH顺序;然后在每一个控制信息资源集合之内,按照PDCCH对应的不同搜索空间ID进行排序;然后对多个控制信息资源集合之内的PDCCH按照控制信息资源集合ID从小到大的顺序进行排序。
方式C4、若第一PDCCH数量为一个载波的一个PDCCH检测机会中至少一个控制信息资源集合中包含的CCE个数之和,根据PDCCH对应的控制信息资源集合的标识信息和控制信息资源集合中的CCE的标识信息的排序,确定PDCCH的排序;
例如,在每一个控制信息资源集合之内,按照控制信息资源集合中的CCE的标识信息(例如为CCE ID)确定PDCCH顺序;然后对多个控制信息资源集合之内的PDCCH按照控制信息资源集合ID从小到大的顺序进行排序。
方式C5、若基站配置的一个载波的一个PDCCH检测机会中传输的第一PDCCH数量大于1时,根据下行控制信息(DCI)中增加的PDCCH排序指示信息,按照PDCCH排序指示信息从小至大的顺序,确定PDCCH的排序;
需要说明的是,该PDCCH排序指示信息的比特位个数通常由第一PDCCH数量确定,即PDCCH排序指示信息的比特位个数=,其中,A为第 一PDCCH数量。
还需要说明的是,在根据所述目标反馈信息的长度,确定反馈码本信息的过程中,若检测到PDCCH个数小于所述第一PDCCH数量时,在未检测到PDCCH对应的PDCCH反馈信息位置填充非应答(NACK)或非连续传输(DTX)的反馈信息。
下面分别对本实施例的具体应用进行分情况说明如下。
情况一、
假设基站配置终端使用半静态码本方案进行反馈,配置终端在载波A上需要接收一个传输块,配置载波A上的CBG大小为2,配置终端在载波A上一个PDCCH传输机会中的控制信息资源集合(CORSET)个数为3,则认为终端在载波A上一个PDCCH传输机会中可接收的最大PDCCH个数为3,则终端对载波A上一个PDCCH检测机会生成3*1*2=6比特的HARQ-ACK信息。对应的3个PDCCH,在不同的CORSET之内进行传输,如图3所示,则按照CORSET ID确定PDCCH顺序,在CORSET 0中进行传输的为PDCCH1,在CORSET 1中进行传输的为PDCCH2,在CORSET 2中进行传输的为PDCCH3。
分别对每个PDCCH调度的PDSCH生成HARQ-ACK反馈信息,然后按照PDCCH顺序将对应的反馈信息进行级联,如图4所示,共得到6个HARQ-ACK反馈比特,其中比特0和比特1对应于在CORSET 0传输的PDCCH调度的PDSCH的两个CBG,比特2和比特3对应于在CORSET 1传输的PDCCH调度的PDSCH的两个CBG,比特4和比特5对应于在CORSET2传输的PDCCH调度的PDSCH的两个CBG。
情况二、
假设基站配置终端使用半静态码本方案进行反馈,配置终端在载波A上需要接收2个传输块,配置载波A上不使用基于CBG的HARQ-ACK反馈,配置终端在载波A上一个PDCCH传输机会中的CORSET个数为2,每个CORSET中的搜索空间个数为2,则认为终端在载波A上一个PDCCH传输机会中可接收的最大PDCCH个数为4,则终端对载波A上一个PDCCH检测机会生成4*2*1=8比特的HARQ-ACK信息。对应的4个PDCCH,分别在不 同的搜索空间之内进行传输,如图5所示,则按照CORSET ID和搜索空间顺序确定PDCCH的排序,在CORSET0的第一个搜索空间中传输的为PDCCH1,在CORSET0的第二个搜索空间中传输的为PDCCH2,在CORSET1的第一个搜索空间中传输的为PDCCH3,在CORSET1的第二个搜索空间中传输的为PDCCH4,假设终端没有检测到在CORSET1的第一个搜索空间中传输的为PDCCH,终端仍然将CORSET1的第二个搜索空间中传输的PDCCH编号为4。
分别对每个PDCCH调度的PDSCH生成HARQ-ACK反馈信息,然后按照PDCCH顺序将对应的反馈信息进行级联,如图6所示,终端共得到8个HARQ-ACK反馈比特,其中比特0和比特1对应于在CORSET 0第一个搜索空间中PDCCH调度的PDSCH的两个传输块(TB),比特2和比特3对应于在CORSET 0第二个搜索空间中PDCCH调度的PDSCH的两个TB,比特4和比特5对应于在CORSET1第一个搜索空间中PDCCH调度的PDSCH的两个TB,由于终端在这个搜索空间中没有检测到PDCCH,则终端产生两个占位比特NACK/DTX,比特6和比特7对应于在CORSET 1第二个搜索空间中PDCCH调度的PDSCH的两个TB。
情况三、
假设基站配置终端使用半静态码本方案进行反馈,配置终端在载波A上需要接收2个传输块,配置载波A上不使用基于CBG的HARQ-ACK反馈,配置终端在载波A上一个PDCCH传输机会中可接收的最大PDCCH个数为4,则终端对载波A上一个PDCCH检测机会生成2*1*4=8比特的HARQ-ACK信息,并且,基站在DCI中通过2比特指示当前载波当前PDCCH检测机会中传输的PDCCH的排序。如图7所示,在CORSET 0中进行传输且具有较小CCE索引的PDCCH编号为00,在CORSET 0中进行传输且具有较大CCE索引的PDCCH编号为01,在CORSET 1中进行传输且具有较小CCE索引的PDCCH编号为10,在CORSET 0中进行传输且具有较大CCE索引的PDCCH编号为11。
假设终端没有接收到CORSET 1中具有较小CCE索引的为PDCCH,终端对接收到的每个PDCCH调度的PDSCH生成HARQ-ACK反馈信息,然后 按照PDCCH的排序将对应的反馈信息进行级联,对没有收到PDCCH的位置产生NACK/DTX,如图8所示,共得到8个HARQ-ACK反馈比特,比特0和比特1对应于编号为00的PDCCH调度的PDSCH的两个TB,比特2和比特3对应于编号为01的PDCCH调度的PDSCH的两个TB,比特4和比特5为NACK/DTX,比特6和比特7对应于编号为11的PDCCH调度的PDSCH的两个TB。
需要说明的是,在本公开实施例中,因基站和终端采用的均是相同反馈码本确定方法,所以基站和终端的之间不存在理解不一致的问题。
需要说明的是,本公开实施例的反馈码本确定方法,在确定反馈码本时考虑了一个PDCCH检测机会中传输多于一个用于调度不同时隙或者同一时隙中不同长度的下行数据传输的PDCCH的情况,产生正确的反馈码本,保证***传输性能,保证了网络通信的可靠性。
