第一时间单元是可用于传输反馈信息的时间单元的起始位置。示例性的,第一时间单元由终端确定;或者,第一时间单元根据激活信令确定。第一时间单元为时隙或子时隙或至少一个时域符号。
终端从第一时间单元开始,逐一时间单元判断当前时间单元中是否有可用的PUCCH资源用于传输反馈信息。若当前时间单元有可用的PUCCH资源,则将当前时间单元确定为第二时间单元,在第二时间单元中进行反馈信息的传输;若当前时间单元没有可用的PUCCH资源,则对下一个时间单元进行判断。若直至判断到最大反馈时间对应的时间单元,仍没有得到第二时间单元,则丢弃该反馈信息。第二时间单元为时隙或子时隙或至少一个时域符号,第二时间单元位于第一时间单元之后,且第二时间单元在最大反馈时间对应的时间单元之前,或第二时间单元是最大反馈时间对应的时间单元。
最大反馈时间对应的时间单元是第一时间单元加上最大反馈时间后指示的时间单元;或者,最大反馈时间对应的时间单元是SPSPDSCH结束传输时所位于的时间单元加上最大反馈时间后指示的时间单元。
示例性的,以在时间单元n中传输的SPSPDSCH为例。确定其第一时间单元为n+k1,最大反馈时间为T。从第一时间单元n+k1开始判断是否有可用的PUCCH资源用于传输SPSPDSCH的反馈信息,若时间单元n+k1中没有,则对时间单元n+k1+1进行判断。若判断有可用的PUCCH资源,则确定当前时间单元为第二时间单元,并在第二时间单元发送反馈信息,停止对之后的时间单元进行判断;若判断没有可用的PUCCH资源,则继续进行下一时间单元的判断。以此类推。若直至时间单元n+k1+T或n+T都没有可用PUCCH资源, 则丢弃该反馈信息。
也即:若根据预配置的反馈时间确定第一时间单元无法传输所述SPSPDSCH的反馈信息,通过第二时间单元发送所述SPSPDSCH的反馈信息;其中,所述第二时间单元在所述第一时间单元之后,且所述第二时间单元在所述最大反馈时间对应的时间单元之前,或第二时间单元是最大反馈时间对应的时间单元。
若根据预配置的反馈时间确定第一时间单元无法传输所述SPSPDSCH的反馈信息,在所述最大反馈时间对应的时间单元以及所述最大反馈时间对应的时间单元之前,不存在用于传输所述SPSPDSCH的反馈信息的第二时间单元,丢弃所述SPSPDSCH的反馈信息。
综上所述,本实施例提供的方法中,通过激活信令确定SPSPDSCH的最大反馈时间,终端基于该最大反馈时间发送或丢弃SPSPDSCH的反馈信息,网络设备基于该最大反馈时间接收SPSPDSCH的反馈信息,使得在不超过最大反馈时间的前提下,尽可能向网络设备发送反馈信息,降低因丢弃反馈信息造成的系统可靠性下降。
上述最大反馈时间可以采用如下三种实现方式中的至少一种来实现:
方式一:由激活信令直接指示最大反馈时间,如图3实施例所示;
方式二:由激活信令所指示的预配置的HARQ时间集合中的最大值来确定,如图7实施例所示;
方式三:由激活信令所指示的n个预配置的HARQ时间集合中的最大值中的最小一个来确定,n为大于1的整数,如图8实施例所示。
图3示出了本申请一个示例性实施例提供的一种反馈信息的发送方法的流程图。本实施例以该方法由终端执行来举例说明。该方法包括:
步骤420:根据激活信令确定SPSPDSCH的最大反馈时间;
激活信令用于激活一个SPSPDSCH配置,SPSPDSCH配置用于配置SPSPDSCH。激活信令直接指示了最大反馈时间。
可选地,最大反馈时间由激活信令的反馈时间信号域(PDSCH-to-HARQ_feedback timing indicator)指示。
示例性的,根据SPSPDSCH对应的激活信令中的反馈时间信号域指示的取值为4,确定最大反馈时间T为4*时间单元,时间单元可以是时隙或子时隙或至少一个时域符号。
步骤440:基于最大反馈时间发送或丢弃SPSPDSCH反馈信息。
终端从第一时间单元开始,逐一时间单元判断当前时间单元中是否有可用的PUCCH资源用于传输反馈信息。若当前时间单元有可用的PUCCH资源,则确定当前时间单元为第二时间单元,并在第二时间单元中进行反馈信息的传输;若当前时间单元没有可用的PUCCH资源,则对下一个时间单元进行判断。若直至判断到最大反馈时间对应的时间单元,仍没有得到第二时间单元,则丢弃该反馈信息。前述最大反馈时间对应的时间单元是第一时间单元加上最大反馈时间后指示的时间单元;或者,是SPSPDSCH结束传输时位于的时间单元加上最大反馈时间后指示的时间单元。第二时间单元为时隙或子时隙或至少一个时域符号,第二时间单元位于第一时间单元之后,且第二时间单元在最大反馈时间对应的时间单元之前,或第二时间单元是最大反馈时间对应的时间单元。
也即:若根据预配置的反馈时间确定第一时间单元无法传输所述SPSPDSCH的反馈信息,通过第二时间单元发送所述SPSPDSCH的反馈信息;其中,所述第二时间单元在所述第一时间单元之后,且所述第二时间单元在所述最大反馈时间对应的时间单元之前,或第二时间单元是最大反馈时间对应的时间单元。
若根据预配置的反馈时间确定第一时间单元无法传输所述SPSPDSCH的反馈信息,在所述最大反馈时间对应的时间单元以及所述最大反馈时间对应的时间单元之前,不存在用于传输所述SPSPDSCH的反馈信息的第二时间单元,丢弃所述SPSPDSCH的反馈信息。
第一时间单元是可用于传输反馈信息的时间单元的起始位置。第一时间单元为时隙或子时隙或至少一个时域符号。
可选地,第一时间单元由传输SPSPDSCH的时间单元n与最小反馈时间t相加得到。最小反馈时间根据网络设备发送的信令确定,或最小反馈时间根据终端处理能力确定,或最小反馈时间由通信协议约定的定时关系确定。
示例性的,第一时间单元根据网络设备发送的信令确定。网络设备针对每套SPSPDSCH配置分别配置最小反馈时间t;或者,网络设备配置一个最小反馈时间t,适用于多套SPSPDSCH配置。传输SPSPDSCH的时间单元n与最小反馈时间t相加得到第一时间单元。
示例性的,第一时间单元根据终端处理能力确定:第一时间单元为包括第一符号的时间单元。其中,第一符号为SPSPDSCH接收完成之后满足处理时延的第一个符号或第一个上行符号,处理时延根据终端能力确定。第一符号包括但不限于第一时域符号和第二时域符号。
具体实现方法有以下两种:
第一种实现方式是确定包括第一时域符号的时间单元为第一时间单元。由公式T proc,1=((N 1+d 1,1+d 1,2)(2048+144)·κ2 )·T c得出处理时延T proc,1。其中,N 1表示终端的处理能力,d 1,1用于指示信道的类型或是指示PDSCH符号的数量,d 1,2用于指示PDSCH符号的数量,κ为64,μ由调度PDSCH的PDCCH的子载波间隔、调度PDSCH的子载波间隔以及用于发送HARQ的上行链路信道的子载波间隔中的其中之一得到最大的T proc,1。第一时域符号为SPSPDSCH结束位置加上T proc,1时间之后的第一个时域符号。例如图4所示,SPSPDSCH接收完成之后满足时延的第一时域符号位于T proc,1右侧箭头指示的位置,第一时域符号位于时间单元n+1中,即最小反馈时间t为1*时间单元,第一时间单元为时间单元n+1。
第二种实现方式是第一时间单元为包括第二时域符号的时间单元。在终端支持PDSCH处理能力2的情况下,即处理能力较强的情况下,当μ=0时,N=5;当μ=1时,N=5.5;当μ=2时,N=11。在终端支持PDSCH处理能力1的情况下,即处理能力较弱的情况下,当μ=0时,N=10;当μ=1时,N=12;当μ=2时,N=22;当μ=3时,N=25。其中,μ是根据SPS PDSCH所使用的子载波间隔与承载反馈信息的PUCCH所使用的子载波间隔中最小的子载波间隔,按照图5的对应关系确定的。例如图6所示,SPSPDSCH接收完成之后满足时延的第二时域符号位于N右侧箭头指示的位置,第二时域符号位于时间单元n+2中,即最小反馈时间为t为2*时间单元,第一时间单元为时间单元n+2。
示例性的,第一时间单元由通信协议约定的定时关系确定。例如,在终端支持PDSCH处理能力2的情况下,即处理能力较强的情况下,最小反馈时间t为1*时间单元;在终端支持PDSCH处理能力1的情况下,即处理能力较弱的情况下,最小反馈时间t为2*时间单元。传输SPSPDSCH的时间单元n与最小反馈时间t相加得到第一时间单元。
最大反馈时间对应的时间单元是指第一时间单元加上最大反馈时间对应的时间单元;或者,最大反馈时间对应的时间单元是SPSPDSCH传输完成时所在的时间单元加上最大反馈时间对应的时间单元。
示例性的,本实施例中以一个在时间单元n中传输的SPSPDSCH为例。基于终端的处理能力确定该SPSPDSCH的最小反馈时延为1*时间单元,即可得到第一时间单元为时间单元n+1。根据最大反馈时间T为4*时间单元,可以得到最大反馈时间T对应的时间单元为时间单元n+5或时间单元n+4。
终端从第一时间单元n+1开始,逐一时间单元判断当前时间单元中是否有可用的PUCCH资源用于传输反馈信息。若当前时间单元有可用的PUCCH资源,则确定当前时间单元为第二时间单元,在第二时间单元中进行反馈信息的传输;若当前时间单元没有可用的PUCCH资源,则对下一个时间单元进行判断。若直至判断到最大反馈时间对应的时间单元,即时间单元n+5或时间单元n+4,仍没有得到第二时间单元,则丢弃该反馈信息。第二时间单元为时隙或子时隙或至少一个时域符号,位于第一时间单元之后,且第二时间单元在最大反馈时 间对应的时间单元之前,或第二时间单元是最大反馈时间对应的时间单元。
综上所述,本实施例提供的方法,通过激活信令确定SPSPDSCH的最大反馈时间,并基于最大反馈时间发送或丢弃SPSPDSCH反馈信息。该方法网络设备能够通过激活信令精确地指示了SPS配置对应的最大反馈时延,使得反馈信息可以在最大反馈时延对应的时间单元及之前的时间单元中选择可用于传输的资源,提供了一种提高传输系统效率,保障反馈消息时延性的方法。

终端从第一时间单元n+1开始,逐一时间单元判断当前时间单元中是否有可用的PUCCH资源用于传输反馈信息。若当前时间单元有可用的PUCCH资源,则确定当前时间单元为第二时间单元,并在第二时间单元中进行反馈信息的传输;若当前时间单元没有可用的PUCCH资源,则对下一个时间单元进行判断。若直至判断到最大反馈时间对应的时间单元,仍没有得到第二时间单元,则丢弃该反馈信息。第二时间单元为时隙或子时隙或至少一个时域符号,第二时间单元位于第一时间单元之后,且第二时间单元在最大反馈时间对应的时间单元之前,或第二时间单元是最大反馈时间对应的时间单元。
也即:若根据预配置的反馈时间确定第一时间单元无法传输所述SPSPDSCH的反馈信息,通过第二时间单元发送所述SPSPDSCH的反馈信息;其中,所述第二时间单元在所述第一时间单元之后,且所述第二时间单元在所述最大反馈时间对应的时间单元之前,或第二时间单元是最大反馈时间对应的时间单元。

若能在根据最大反馈时间T确定的时间单元及之前,得到第二时间单元,该第二时间单 元为时隙或子时隙或至少一个时域符号,存在可用于传输SPSPDSCH的反馈信息的PUCCH资源,则在该第二时间单元传输SPSPDSCH的反馈信息,对第二时间单元之后的时间单元不再进行判断。
步骤346b:丢弃SPSPDSCH的反馈信息。
若在根据最大反馈时间T确定的时间单元及之前,未能得到第二时间单元,该第二时间单元中存在可用于传输SPSPDSCH的反馈信息的PUCCH资源,则丢弃该SPSPDSCH的反馈信息。

图10示出了本申请一个示例性实施例提供的反馈信息的接收方法的流程图。本实施例以该方法由网络设备来执行来举例说明。该方法包括:
步骤720:根据激活信令确定SPSPDSCH的最大反馈时间;
激活信令用于激活一个SPSPDSCH配置,SPSPDSCH配置用于配置SPSPDSCH。
最大反馈时间是保证反馈信息能够满足时延要求的时长。反馈信息是终端对SPSPDSCH是否成功接收的HARQ反馈信息,比如,确认信息(ACK)代表成功接收,否认信息(NACK)代表未能成功接收。可选地,最大反馈时间由网络设备基于SPSPDSCH的业务时延要求来确定。
示意性的,最大反馈时间由激活信令指示;或者,最大反馈时间是基于激活信令对应的预配置的混合自动重传请求(Hybrid Automatic Repeat Request,HARQ)时间集合中的最大值确定的;再或者,在激活信令对应的DCI格式包括n种DCI格式的情况下,n为大于1的整数,n种DCI格式对应有n个预配置HARQ时间集合,n个预配置HARQ时间集合中的每个预配置HARQ时间集合具有最大值。最大反馈时间是基于n个最大值中的最小一个确定的。或者理解为,最大反馈时间是基于n个最大值中的最小值确定的。
步骤740:基于最大反馈时间接收SPSPDSCH反馈信息。
第一时间单元是可用于传输反馈信息的时间单元的起始位置。示例性的,第一时间单元根据网络设备发送的信令,或者终端处理能力,或者通信协议约定的定时关系确定;或者,第一时间单元根据激活信令确定。第一时间单元为时隙或子时隙或至少一个时域符号。
网络设备从第一时间单元开始,逐一时间单元判断当前时间单元中是否有可用的PUCCH资源用于传输反馈信息。若当前时间单元有可用的PUCCH资源,则将当前时间单元确定为第二时间单元,在第二时间单元中接收反馈信息;若当前时间单元没有可用的PUCCH资源,则对下一个时间单元进行判断。若直至判断到最大反馈时间对应的时间单元,仍没有得到第二时间单元,则放弃接收该反馈信息。第二时间单元为时隙或子时隙或至少一个时域符号,第二时间单元位于第一时间单元之后,且第二时间单元在最大反馈时间对应的时间单元之前。
最大反馈时间对应的时间单元是第一时间单元加上最大反馈时间后指示的时间单元;或者,最大反馈时间对应的时间单元是SPSPDSCH结束传输时所位于的时间单元加上最大反馈时间后指示的时间单元。
也即:若根据预配置的反馈时间确定第一时间单元无法传输所述SPSPDSCH的反馈信息,通过第二时间单元接收所述SPSPDSCH的反馈信息;其中,所述第二时间单元在所述第一时间单元之后,且所述第二时间单元在所述最大反馈时间对应的时间单元之前,或第二时间单元是最大反馈时间对应的时间单元。
若根据预配置的反馈时间确定第一时间单元无法传输所述SPSPDSCH的反馈信息,在所述最大反馈时间对应的时间单元以及所述最大反馈时间对应的时间单元之前,不存在用于传输所述SPSPDSCH的反馈信息的第二时间单元,放弃接收所述SPSPDSCH的反馈信息。示例性的,以在时间单元n中传输的SPSPDSCH为例。确定其第一时间单元为n+k1,最大反馈时间为T。从第一时间单元n+k1开始判断是否有可用的PUCCH资源用于传输SPSPDSCH的反馈信息,若时间单元n+k1中没有,则对时间单元n+k1+1进行判断。若判断有可用的PUCCH资源,则确定当前时间单元为第二时间单元,并在第二时间单元接收反馈信息,停止对之后的时间单元进行判断;若判断没有可用的PUCCH资源,则继续进行下一时间单元的判断。以此类推。若直至时间单元n+k1+T或n+T都没有可用PUCCH资源,则放弃接收该反馈信息。
综上所述,本实施例提供的方法中,根据激活信令确定SPSPDSCH的最大反馈时间,并且基于最大反馈时间选择是否接收SPSPDSCH反馈信息。该方法能够通过延迟SPSPDSCH对应的反馈信息的传输时间,使得因在预配置的HARQ时间单元中没有PUCCH资源而被丢弃的反馈信息得以被传输,避免了因反馈信息被丢弃造成的系统效率降低。此外,本方法通过确定最大反馈时间,对最大反馈时间对应的时间单元及之前没有找到用于传输的资源的反馈信息不予接收,保障了反馈信息的时效性。
由网络设备执行的反馈信息的接收方法与由终端执行的反馈信息的发送方法类似,另可参考步骤320至步骤346b,步骤420至步骤440,步骤520至步骤540,以及步骤620至步骤640,这里不再赘述。
