技术领域
本发明涉及通信技术领域,具体公开了一种参考信号的位置确定方法、指示方法及相关产品。
背景技术
新无线(new radio,NR)系统中,终端设备与网络设备上下行的传输过程中可以进行多个重复(repetition)的传输,即在该多个repetition上传输相同的信息。发送端需要在每个repetition对应时域资源上,发送一个或多个参考信号(reference signal,RS),以便接收端进行估计,解调出发送端在该repetition上所发送的信息。
在信道缓变的情况下,终端设备与网络设备之间可以采用较少的参考信号进行重复传输。即指在某些repetition对应的时域资源上不发送RS,因为信道缓变,该repetition对应的估计可以通过在前面repetition所对应的时域资源上发送的RS实现。
然而,用较少的参考信号进行重复传输会改变RS和repetition之间的对应关系,网络设备如何指示RS的位置以及终端设备如何确定RS的位置,仍处于空白阶段。
发明内容
本申请提供了一种参考信号的位置确定方法、指示方法及相关产品。在通过较少的参考信号进行传输的过程中,可以精确的确定出哪些重复传输资源承载有解调参考信号,哪些重复传输资源没有承载解调参考信号,弥补了现有技术的空白。
第一方面,本申请实施例提供一种参考信号的位置确定方法,该方法的执行主体可以是终端设备,也可以是应用于终端设备中的芯片。下面以执行主体是终端设备为例进行描述。
确定至少两个重复传输资源中承载参考信号的至少一个第一重复传输资源,其中,所述至少两个重复传输资源中存在未承载参考信号的第二重复传输资源;
在所述至少一个第一重复传输资源上接收参考信号和下行信道的重复,在所述第二重复传输资源上接收所述下行信道的重复,或者,在所述至少一个第一重复传输资源上发送参考信号和上行信道的重复,在所述第二重复传输资源上发送所述上行信道的重复。
可以看出,在本申请实施例中,终端设备在进行重复传输的过程中,可以通过较少的参考信号进行重复传输,而且在这种传输模式下,可以精确的确定出哪些重复传输资源承载有参考信号,哪些重复传输资源没有承载参考信号,弥补了现有技术的空白。另外,采用较少的参考信号进行重复传输,与现有的重复传输方式相比,可以节省一部分时域资源,而节省下来的时域资源可以用来传输数据,进而提高了与网络设备之间的通信效率。
第二方面,本申请提供一种参考信号的位置确定方法,该方法的执行主体可以是终端设备,也可以是应用于终端设备中的芯片。下面以执行主体是终端设备为例进行描述。该方法包括:
确定至少两个重复传输资源中承载参考信号的至少一个第一重复传输资源,其中,所述至少两个重复传输资源中存在承载参考信号的第二重复传输资源,且所述至少一个第一重复传输资源中每个第一重复传输资源用于承载参考信号的重复传输资源的数量多于所述第二重复传输资源中用于承载参考信号的重复传输资源的数量;即第一重复传输资源上承载有相对较多的参考信号,第二重复传输资源上承载有相对较少的参考信号;
在所述至少一个第一重复传输资源上接收参考信号和下行信道的重复,在所述第二重复传输资源上接收参考信号和所述下行信道的重复,或者,在所述至少一个第一重复传输资源上发送参考信号和上行信道的重复,在所述第二重复传输资源上发送参考信号和所述上行信道的重复。
可以看出,在本申请实施例中,在进行重复传输的过程中,可以在一些重复传输资源上使用相对较少的资源承载参考信号,而且在这种传输模式下,可以精确的确定出哪些重复传输资源承载相对较多的参考信号,哪些重复传输资源相对较少的承载参考信号,弥补了现有技术的空白。另外,在一些重复传输资源上使用相对较少的资源承载参考信号进行重复传输,与现有的重复传输方式相比,这些重复传输资源上会节省下来一部资源用来传输数据,提高了与网络设备之间的通信效率。
结合第一方面和第二方面,在一些可能的实施方式中,确定至少两个重复传输资源中承载参考信号的至少一个第一重复传输资源之前,所述方法还包括:

可以看出,在本实施方式中,终端设备可以直接根据两个重复传输资源的数量以及至少一个第一重复传输资源的数量,确定出任意两个相邻的第一重复传输资源之间的间隔,无需去考虑处于时域边缘位置的第一传输资源会存在重复传输资源不均匀的问题,提高确定第一重复传输资源的位置的效率,进而提高重复传输的效率。
结合第一方面和第二方面,在一些可能的实施方式中,所述至少一个第一重复传输资源包括前m1个第一重复传输资源和后m2个第一重复传输资源;
所述根据所述至少两个重复传输资源的数量以及所述至少一个第一重复传输资源的数量,确定所述至少一个第一重复传输资源在所述至少两个重复传输资源中的位置,包括:
根据所述至少两个重复传输资源的数量以及所述至少一个第一重复传输资源的数量,分别确定所述前m1个第一重复传输资源在所述至少两个重复传输资源中的位置,以及所述后m2个第一重复传输资源在所述至少两个重复传输资源中的位置,其中,所述至少两个重复传输资源中的第一个重复传输资源承载有解调参考信号;
其中,所述前m1个第一重复传输资源中任意两个相邻的第一重复传输资源之间的第一间隔与所述后m2个第一重复传输资源中任意两个相邻的第一重复传输资源之间的第二间隔不同,且所述前m1个第一重复传输资源中的最后一个第一重复传输资源和所述后m2个第一重复传输资源中的第一个第一重复传输资源之间的间隔为所述第一间隔。
可以看出,在本实施方式中,终端设备考虑到处于时域边缘位置的第一传输资源会存在重复传输资源不均匀的问题,可提前将第一重复传输资源拆分成前后两部分,使第一重复传输资源的分布更加均匀,进而对信道的估计更加精确与合理。
结合第一方面和第二方面,在一些可能的实施方式中,确定至少两个重复传输资源中承载参考信号的至少一个第一重复传输资源之前,所述方法还包括:
接收网络设备发送的所述至少两个重复传输资源的数量以及标称的相邻的第一重复传输资源之间的间隔;
所述确定至少两个重复传输资源中承载参考信号的至少一个第一重复传输资源,包括:
根据所述至少两个重复传输资源的数量以及所述标称的相邻的第一重复传输资源之间的间隔,确定所述至少一个第一重复传输资源在所述至少两个重复传输资源中的位置。
可以看出,在本实施方式中,终端设备可以通过网络设备发送的至少两个重复传输资源的数量以及标称的相邻的第一重复传输资源之间的间隔,确定出第一重复传输资源的位置。因此,终端设备可以通过比较灵活的方式确定出第一重复传输资源的位置。
结合第一方面和第二方面,在一些可能的实施方式中,所述标称的相邻的第一重复传输资源之间的间隔为所述至少一个第一重复传输资源中任意两个相邻的第一重复传输资源之间的间隔;
所述根据所述至少两个重复传输资源的数量以及所述标称的相邻的第一重复传输资源之间的间隔,确定所述至少一个第一重复传输资源在所述至少两个重复传输资源中的位置,包括:
根据所述至少两个重复传输资源的数量以及所述至少一个第一重复传输资源中任意两个相邻的第一重复传输资源之间的间隔,确定所述至少一个第一重复传输资源在所述至少两个重复传输资源中的位置。
可以看出,在本实施方式中,终端设备可以将标称的相邻的第一重复传输资源之间的间隔作为任意两个相邻的第一重复传输资源之间的间隔,无需去考虑处于时域边缘位置的第一传输资源会存在重复传输资源不均匀的问题,提高确定第一重复传输资源的位置的效率。
结合第一方面和第二方面,在一些可能的实施方式中,所述至少一个第一重复传输资源包括前n1个第一重复传输资源和后n2个第一重复传输资源;
所述根据所述至少两个重复传输资源的数量以及所述标称的相邻的第一重复传输资源之间的间隔,确定所述第一重复传输资源在所述至少两个重复传输资源中的位置,包括:
根据所述至少两个重复传输资源的数量以及所述标称的相邻的第一重复传输资源之间的间隔,确定所述至少一个第一重复传输资源的数量;
根据所述至少两个重复传输资源的数量以及所述至少一个第一重复传输资源的数量,分别确定所述前n1个第一重复传输资源在所述至少两个重复传输资源中的位置,以及所述后 n2个第一重复传输资源在所述至少两个重复传输资源中的位置,其中,所述至少两个重复传输资源中的第一个重复传输资源承载有解调参考信号;
其中,所述前n1个第一重复传输资源中任意两个相邻的第一重复传输资源之间的第三间隔与所述后n2个第一重复传输资源中任意两个相邻的第一重复传输资源之间的第四间隔不同,且所述前n1个第一重复传输资源中的最后一个第一重复传输资源和所述后n2个第一重复传输资源中的第一个第一重复传输资源之间的间隔为所述第三间隔。
可以看出,在本实施方式中,终端设备会考虑到处于时域边缘位置的第一传输资源会存在重复传输资源不均匀的问题,可提前将第一重复传输资源拆分成前后两部分;然后,分别确定前后两部分中每个第一重复传输资源的位置,使第一重复传输资源的分布更加均匀,进而对信道的估计更加精确与合理。
结合第一方面和第二方面,在一些可能的实施方式中,在确定至少两个重复传输资源中承载参考信号的至少一个第一重复传输资源之前,所述方法还包括:
接收网络设备发送的第一消息,所述第一消息用于确定所述至少两个重复传输资源中的重复传输资源i被取消;
所述根据所述至少两个重复传输资源的数量以及所述标称的相邻的第一重复传输资源之间的间隔,确定所述至少一个第一重复传输资源在所述至少两个重复传输资源中的位置,包括:
根据所述至少两个重复传输资源的数量、所述标称的相邻的第一重复传输资源之间的间隔以及所述重复传输资源i,确定所述至少一个第一重复传输资源在所述至少两个重复传输资源中的位置。
可以看出,在本实施方式中,若终端设备可以提前预知到某个重复传输资源被取消,则可以结合被取消的重复传输资源,来确定第一重复传输资源的位置,使第一重复传输资源的分布更加合理,不会受被取消的重复传输资源的影响。
结合第一方面和第二方面,在一些可能的实施方式中,所述根据所述至少两个重复传输资源的数量、所述标称的相邻的第一重复传输资源之间的间隔以及所述重复传输资源i,确定所述至少一个第一重复传输资源在所述至少两个重复传输资源中的位置,包括:
确定所述至少两个重复传输资源中位于所述重复传输资源i之后的未被取消的重复传输资源的第一数量;
根据所述第一数量和所述标称的相邻的第一重复传输资源之间的间隔,确定位于所述重复传输资源i之后的未被取消的重复传输资源中第一重复传输资源的位置,其中,位于所述重复传输资源i之后的未被取消的重复传输资源中的第一个重复传输资源承载有参考信号。
可以看出,在本实施方式中,终端设备不会将第一重复传输资源分配到该重复传输资源i的位置,并且在位于该重复传输资源i之后的未被取消的重复传输资源中的第一个重复传输资源上承载有参考信号,则在该重复传输资源i被中断后,位于该重复传输资源i之后的未被取消的重复传输资源仍然可以有参考信号可以使用,不会增加接收端的存储。
结合第一方面和第二方面,在一些可能的实施方式中,所述根据所述至少两个重复传输资源的数量、所述标称的相邻的第一重复传输资源之间的间隔以及所述重复传输资源i,确定所述至少一个第一重复传输资源在所述至少两个重复传输资源中的位置,包括:
确定所述至少两个重复传输资源中位于所述重复传输资源i之前的未被取消传输的重复传输资源的第二数量;
根据所述第二数量和所述标称的相邻的第一重复传输资源之间的间隔,确定位于所述重 复传输资源i之前的未被取消的重复传输资源中第一重复传输资源的位置。
可以看出,在本实施方式中,在重复传输资源i被取消的情况下,终端设备将位于该重复传输资源i之前的未被取消传输的重复传输资源看做多个连续的新的重复传输资源,进行第一重复传输资源的确定,从而可以在某个重复传输资源被取消的情况下,仍然可以使位于该重复传输资源i之前的未被取消传输的重复传输资源的分布比较均匀。
结合第一方面和第二方面,在一些可能的实施方式中,所述根据所述至少两个重复传输资源的数量、所述标称的相邻的第一重复传输资源之间的间隔以及所述重复传输资源i,确定所述至少一个第一重复传输资源在所述至少两个重复传输资源中的位置,包括:
在确定距离所述重复传输资源i之前的最近一个未被取消的重复传输资源和之后的最近一个未被取消的重复传输资源的发送相位不连续的情况下,或者,在确定距离所述重复传输资源i之前的最近一个未被取消传输的重复传输资源和之后的最近一个未被取消传输的重复传输资源的发送功率差异不在所述网络设备配置的第一区域范围内的情况下,根据所述至少两个重复传输资源的数量、所述标称的相邻的第一重复传输资源之间的间隔以及所述重复传输资源i,确定所述至少一个第一重复传输资源在所述至少两个重复传输资源中的位置。
可以看出,在本实施方式中,终端设备先确定发送相位是否连续或者发送功率差异是否不在网络设备配置的第一区域范围内,如果是,则确定在重复传输资源i被取消的前后,所使用的信道不同,从而需要将重复传输资源i考虑在内来确定第一重复传输资源的位置;如果不是,则确定重复传输资源i即使被取消,在重复传输资源i被取消的前后,所使用的信道相同,可以按照正常的方式来确定第一重复传输资源的位置,增加了确定第一重复传输资源的灵活性。
结合第一方面和第二方面,在一些可能的实施方式中,在确定至少两个重复传输资源中承载参考信号的至少一个第一重复传输资源之后,所述方法还包括:
接收网络设备发送的第二消息,所述第二消息用于确定所述至少两个重复传输资源中的重复传输资源j被取消;
根据所述重复传输资源j,调整所述至少一个第一重复传输资源在所述至少两个重复传输资源中的位置。
可以看出,在本实施方式中,若终端设备不能提前预知到重复传输资源j被取消,则在按照正常的方式确定好第一重复传输资源的位置后,需要根据该重复传输资源j重新调整第一重复传输资源的位置,从而使第一重复传输资源的位置分布更加合理,对信道的估计更加准确。
结合第一方面和第二方面,在一些可能的实施方式中,所述根据所述重复传输资源j,调整所述至少一个第一重复传输资源在所述至少两个重复传输资源中的位置,包括:
确定所述至少两个重复传输资源中位于所述重复传输资源j之后的未被取消的重复传输资源的第三数量,以及位于所述重复传输资源j之后的未被取消的第一重复传输资源的第四数量;
根据所述第三数量和所述第四数量,确定位于所述重复传输资源j之后的未被取消的重复传输资源中第一重复传输资源的位置,其中,位于所述重复传输资源j之后的未被取消的重复传输资源中的第一个重复传输资源承载有参考信号。
可以看出,在本实施方式中,终端设备可以只调整位于重复传输资源j之后的未被取消的重复传输资源中第一重复传输资源的位置,这样可以更快的调整好第一重复传输资源的位置,提高重复传输的效率。
结合第一方面和第二方面,在一些可能的实施方式中,所述确定所述至少两个重复传输资源中位于所述重复传输资源j之后的未被取消的重复传输资源的第三数量,以及位于所述重复传输资源j之后的未被取消的第一重复传输资源的第四数量,包括:
在确定第一时间间隔大于或等于第一阈值的情况下,确定所述至少两个重复传输资源中位于所述重复传输资源j之后的未被取消的重复传输资源的第三数量,以及位于所述重复传输资源j之后的未被取消的重复传输资源的第四数量;
其中,所述第一阈值是根据所述终端设备进行数据传输的准备时长确定的,所述第一时间间隔为第一时间和第二时间之间的时间间隔,所述第一时间为所述重复传输资源j之后的未被取消的重复传输资源的开始时间,所述第二时间为接收到所述第二消息的结束时间。
可以看出,在本实施方式中,终端设备先判断第一时间间隔是否大于或等于第一阈值,如果是,则说明还来得及调整位于重复传输资源j之后的未被取消的重复传输资源中第一重复传输资源的位置,此时再去调整,保证调整的合理性。
结合第一方面和第二方面,在一些可能的实施方式中,所述根据所述重复传输资源j,调整所述至少一个第一重复传输资源在所述至少两个重复传输资源中的位置,包括:
确定所述至少两个重复传输资源中位于所述重复传输资源j之前的未被取消的重复传输资源的第五数量,以及位于所述重复传输资源j之前的未被取消的第一重复传输资源的第六数量;
根据所述第五数量和所述第六数量,确定位于所述重复传输资源j之前的未被取消的重复传输资源中第一重复传输资源的位置,其中,位于所述重复传输资源j之前的未被取消的重复传输资源中的第一个重复传输资源承载有解调参考信号。
可以看出,在本实施方式中,终端设备还可以去调整位于重复传输资源j之前的未被取消的重复传输资源中第一重复传输资源的位置,这样可以使重复传输资源j前的未被取消的重复传输资源中第一重复传输资源的分布都比较合理与均匀,这样终端设备在进行位于重复传输资源j前的重复传输的过程中,可以使用该第一重复传输资源上的参考信号进行准确地信道估计。
结合第一方面和第二方面,在一些可能的实施方式中,所述确定所述至少两个重复传输资源中位于所述重复传输资源j之前的未被取消的重复传输资源的第五数量,以及位于所述重复传输资源j之前的未被取消的重复传输资源的第六数量,包括:
在确定第二时间间隔大于或等于第一阈值的情况下,确定所述至少两个重复传输资源中位于所述重复传输资源j之前的未被取消的重复传输资源的第五数量,以及位于所述重复传输资源j之前的未被取消的第一重复传输资源的第六数量;
其中,所述第一阈值是根据所述终端设备进行数据传输的准备时长确定的,所述第二时间间隔为第二时间和第三时间之间的时间间隔,所述第二时间为接收到所述第二消息的结束时间,所述第三时间为所述至少两个重复传输资源中的第一个重复传输资源的开始时间。
可以看出,在本实施方式中,终端设备先判断第二时间间隔是否大于或等于第一阈值,如果是,则说明终端设备还没有使用位于重复传输资源j之前的未被取消的重复传输资源进行重复传输,这个时候可以去调整位于重复传输资源j之前的未被取消的重复传输资源中第一重复传输资源的位置,进而保证调整的合理性。
结合第一方面和第二方面,在一些可能的实施方式中,在确定距离所述重复传输资源j之前的最近一个未被取消的重复传输资源和之后的最近一个未被取消的重复传输资源的发送相位不连续的情况下,或者,在确定距离所述重复传输资源j之前的最近一个未被取消传输 的重复传输资源和之后的最近一个未被取消传输的重复传输资源的发送功率差异不在所述网络设备配置的第一区域范围内的情况下,根据所述重复传输资源j,调整所述至少一个第一重复传输资源在所述至少两个重复传输资源中的位置。
可以看出,在本实施方式中,在重复传输资源j被取消的情况下,终端设备先确定发送相位是否连续或者发送功率差异是否不在网络设备配置的第一区域范围内,如果是,则确定在重复传输资源i被取消的前后,所使用的信道不同,从而需要将重新调整第一重复传输的位置;如果不是,则可以按照之前确好的第一重复传输资源的位置,进行重复传输,无需重新调整,避免额外调整,给终端设备带来处理压力。
第三方面,本申请实施例提供一种参考信号的位置指示方法,该方法的执行主体可以是网络设备,也可以是应用于网络设备中的芯片。下面以执行主体是网络设备为例进行描述。

可以看出,在本实施方式中,在重复传输资源i被取消的情况下,网络设备指示终端设备将位于该重复传输资源i之前的未被取消传输的重复传输资源看做多个连续的新的重复传输资源,进行第一重复传输资源的确定,从而可以在某个重复传输资源被取消的情况下,仍然可以使位于该重复传输资源i之前的未被取消传输的重复传输资源的分布比较均匀。
结合第三方面和第四方面,在一些可能的实施方式中,所述根据所述至少两个重复传输资源的数量、所述标称的相邻的第一重复传输资源之间的间隔以及所述重复传输资源i,确定所述至少一个第一重复传输资源在所述至少两个重复传输资源中的位置,包括:
在确定距离所述重复传输资源i之前的最近一个未被取消的重复传输资源和之后的最近一个未被取消的重复传输资源的发送相位不连续的情况下,或者,在确定距离所述重复传输资源i之前的最近一个未被取消传输的重复传输资源和之后的最近一个未被取消传输的重复传输资源的发送功率差异不在所述网络设备配置的第一区域范围内的情况下,根据所述至少两个重复传输资源的数量、所述标称的相邻的第一重复传输资源之间的间隔以及所述重复传输资源i,确定所述至少一个第一重复传输资源在所述至少两个重复传输资源中的位置。
可以看出,在本实施方式中,网络设备指示终端设备先确定发送相位是否连续或者发送功率差异是否不在网络设备配置的第一区域范围内,如果是,则确定在重复传输资源i被取消的前后,所使用的信道不同,从而需要将重复传输资源i考虑在内来确定第一重复传输资源的位置;如果不是,则确定重复传输资源i即使被取消,在重复传输资源i被取消的前后,所使用的信道相同,可以按照正常的方式来确定第一重复传输资源的位置,增加了确定第一重复传输资源的灵活性。
结合第三方面和第四方面,在一些可能的实施方式中,向终端设备发送所述至少两个重复传输资源的数量以及所述至少一个第一重复传输资源的数量之后,所述方法还包括:
向网络设备发送第二消息,所述第二消息用于指示所述至少两个重复传输资源中的重复传输资源j被取消;以及指示所述终端设备根据所述重复传输资源j,调整所述至少一个第一重复传输资源在所述至少两个重复传输资源中的位置。
可以看出,在本实施方式中,网络设备在终端设备确定了第一重复传输位置,发现有高优先级的传输需要传输,则通过终端设备重复传输资源j被取消,并指示终端设备在按照正常的方式确定好第一重复传输资源的位置后,需要根据该重复传输资源j重新调整第一重复 传输资源的位置,从而使第一重复传输资源的位置分布更加合理,对信道的估计更加准确。
结合第三方面和第四方面,在一些可能的实施方式中,所述根据所述重复传输资源j,调整所述至少一个第一重复传输资源在所述至少两个重复传输资源中的位置,包括:
确定所述至少两个重复传输资源中位于所述重复传输资源j之后的未被取消的重复传输资源的第三数量,以及位于所述重复传输资源j之后的未被取消的第一重复传输资源的第四数量;
根据所述第三数量和所述第四数量,确定位于所述重复传输资源j之后的未被取消的重复传输资源中第一重复传输资源的位置,其中,位于所述重复传输资源j之后的未被取消的重复传输资源中的第一个重复传输资源承载有参考信号。
可以看出,在本实施方式中,网络设备指示终端设备可以只调整位于重复传输资源j之后的未被取消的重复传输资源中第一重复传输资源的位置,这样可以更快的调整好第一重复传输资源的位置,提高重复传输的效率。
结合第三方面和第四方面,在一些可能的实施方式中,所述确定所述至少两个重复传输资源中位于所述重复传输资源j之后的未被取消的重复传输资源的第三数量,以及位于所述重复传输资源j之后的未被取消的第一重复传输资源的第四数量,包括:
在确定第一时间间隔大于或等于第一阈值的情况下,确定所述至少两个重复传输资源中位于所述重复传输资源j之后的未被取消的重复传输资源的第三数量,以及位于所述重复传输资源j之后的未被取消的重复传输资源的第四数量;
其中,所述第一阈值是根据所述终端设备进行数据传输的准备时长确定的,所述第一时间间隔为第一时间和第二时间之间的时间间隔,所述第一时间为所述重复传输资源j之后的未被取消的重复传输资源的开始时间,所述第二时间为接收到所述第二消息的结束时间。
可以看出,在本实施方式中,网络设备指示终端设备先判断第一时间间隔是否大于或等于第一阈值,如果是,也就是说还来得及调整位于重复传输资源j之后的未被取消的重复传输资源中第一重复传输资源的位置,此时再去调整,保证调整的合理性。
结合第三方面和第四方面,在一些可能的实施方式中,所述根据所述重复传输资源j,调整所述至少一个第一重复传输资源在所述至少两个重复传输资源中的位置,包括:
确定所述至少两个重复传输资源中位于所述重复传输资源j之前的未被取消的重复传输资源的第五数量,以及位于所述重复传输资源j之前的未被取消的第一重复传输资源的第六数量;
根据所述第五数量和所述第六数量,确定位于所述重复传输资源j之前的未被取消的重复传输资源中第一重复传输资源的位置,其中,位于所述重复传输资源j之前的未被取消的重复传输资源中的第一个重复传输资源承载有解调参考信号。
可以看出,在本实施方式中,网络设备指示终端设备还可以去调整位于重复传输资源j之前的未被取消的重复传输资源中第一重复传输资源的位置,这样可以使重复传输资源j前的未被取消的重复传输资源中第一重复传输资源的分布都比较合理与均匀,这样终端设备在进行位于重复传输资源j前的重复传输的过程中,可以使用该第一重复传输资源上的参考信号进行准确地信道估计。
结合第三方面和第四方面,在一些可能的实施方式中,所述确定所述至少两个重复传输资源中位于所述重复传输资源j之前的未被取消的重复传输资源的第五数量,以及位于所述重复传输资源j之前的未被取消的重复传输资源的第六数量,包括:
在确定第二时间间隔大于或等于第一阈值的情况下,确定所述至少两个重复传输资源中 位于所述重复传输资源j之前的未被取消的重复传输资源的第五数量,以及位于所述重复传输资源j之前的未被取消的第一重复传输资源的第六数量;
其中,所述第一阈值是根据所述终端设备进行数据传输的准备时长确定的,所述第二时间间隔为第二时间和第三时间之间的时间间隔,所述第二时间为接收到所述第二消息的结束时间,所述第三时间为所述至少两个重复传输资源中的第一个重复传输资源的开始时间。
可以看出,在本实施方式中,网络设备指示终端设备先判断第二时间间隔是否大于或等于第一阈值,如果是,则说明终端设备还没有使用位于重复传输资源j之前的未被取消的重复传输资源进行重复传输,这个时候可以去调整位于重复传输资源j之前的未被取消的重复传输资源中第一重复传输资源的位置,进而保证调整的合理性。
结合第三方面和第四方面,在一些可能的实施方式中,所述根据所述重复传输资源j,调整所述至少一个第一重复传输资源在所述至少两个重复传输资源中的位置,包括:
在确定距离所述重复传输资源j之前的最近一个未被取消的重复传输资源和之后的最近一个未被取消的重复传输资源的发送相位不连续的情况下,或者,在确定距离所述重复传输资源j之前的最近一个未被取消传输的重复传输资源和之后的最近一个未被取消传输的重复传输资源的发送功率差异不在所述网络设备配置的第一区域范围内的情况下,根据所述重复传输资源j,调整所述至少一个第一重复传输资源在所述至少两个重复传输资源中的位置。
可以看出,在本实施方式中,在重复传输资源j被取消的情况下,网络设备指示终端设备先确定发送相位是否连续或者发送功率差异是否不在网络设备配置的第一区域范围内,如果是,则确定在重复传输资源i被取消的前后,所使用的信道不同,从而需要将重新调整第一重复传输的位置;如果不是,则可以按照之前确好的第一重复传输资源的位置,进行重复传输,无需重新调整,避免额外调整,给终端设备带来处理压力。

具体实施方式
本申请实施例中的技术方案,可应用于各种通信系统。比如,第五代(5th generation,5G)移动通信系统以及未来的移动通信系统等。
本申请实施例涉及的终端设备,例如,可以为用户设备(User Equipment,UE)。该UE可以为向用户提供语音和/或数据连通性的设备,例如可以包括具有无线连接功能的手持式设备、或连接到无线调制解调器的处理设备。该UE可以经无线接入网(radio access network,RAN)与核心网进行通信,与RAN交换语音和/或数据。UE可以包括无线用户设备、移动用户设备、设备到设备通信(device-to-device,D2D)用户设备、车到一切(vehicle-to-everything,V2X)用户设备、机器到机器/机器类通信(machine-to-machine/machine-type communications,M2M/MTC)用户设备、物联网(internet of things,IoT)用户设备、订户单元(subscriber unit)、订户站(subscriber station),移动站(mobile station)、远程站(remote station)、接入点(access point,AP)、远程终端(remote terminal)、接入终端(access terminal)、用户终端(user terminal)、用户代理(user agent)、或用户装备(user device)等。例如,可以包括移动电话(或称为“蜂窝”电话),具有移动用户设备的计算机,便携式、袖珍式、手持式、计算机内置的移动装置等。例如,个人通信业务(personal communication service,PCS)电话、无绳电话、会话发起协议(session initiation protocol,SIP)话机、无线本地环路(wireless local loop,WLL)站、个人数字助理(personal digital assistant,PDA)、等设备。还包括受限设备,例如功耗较低的设备,或存储能力有限的设备,或计算能力有限的设备等。例如包括条码、射频识别(radio frequency identification,RFID)、传感器、全球定位系统(global positioning system,GPS)、激光扫描器等信息传感设备。
作为示例而非限定,在本申请实施例中,该UE还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备或智能穿戴式设备等,是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称,如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上,或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备,更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能,例如:智能手表或智能眼镜等,以及只专注于某一类应用功能,需要和其它设备如智能手机配合使用,如各类进行体征监测的智能手环、智能头盔、智能首饰等。
而如上介绍的各种UE,如果位于车辆上(例如放置在车辆内或安装在车辆内),都可以认为是车载用户设备,车载用户设备例如也称为车载单元(on-board unit,OBU),本申请实施例对此不作限定。
本申请实施例还涉及网络设备,例如可以为接入网(Access network,AN)设备。该AN设备可以是指接入网中在空口通过一个或多个小区与无线用户设备通信的设备,例如基站NodeB(例如,接入点),该NodeB可用于将收到的空中帧与网际协议(IP)分组进行相互转换,作为UE与接入网的其余部分之间的路由器,其中,该接入网的其余部分可包括IP网络且。例如,该NodeB可以是长期演进(long term evolution,LTE)系统或高级长期演进(long term evolution-advanced,LTE-A)中的演进型基站(NodeB或eNB或e-NodeB,evolutional Node B),或者也可以包括第五代移动通信技术(the 5th generation,5G)NR系统中的新空口网络设备gNB。该AN设备还可以是一种车到一切(Vehicle to Everything,V2X)技术中的接入网设备为路侧单元(road side unit,RSU)。该RSU可以是支持V2X应用的固定基础设施实体,可以与支持V2X应用的其他实体交换消息。另外,AN设备还可以包括云接入网(cloud radio access network,CloudRAN)系统中的集中式单元(centralized unit,CU)和分布式单元 (distributed unit,DU),此时,该AN设备协调对空口的属性管理。本申请实施例对AN设备不作限定。
为了便于理解本申请,首先在此介绍本申请实施例涉及的相关技术知识。
NR系统中,终端设备与网络设备上下行的传输过程中可以进行多个repetition传输,即在该多个repetition上传输相同的信息。发送端需要在每个repetition对应时域资源上,发送一个或多个RS,以便终端设备或网络设备进行估计,比如,该RS可以为解调参考信号(demodulation reference signal,DM-RS),终端设备或网络设备使用该DM-RS进行信道估计,从而解调出发送端在该repetition上所发送的信息。
如图1所示,每个方框代表一个repetition,该方框中的灰色方框表示发送端发送每个repetition对应的DM-RS时,所要使用的时域资源的位置。可以看出,发送端在相应的时域资源上发送与每个repetition对应的一个DM-RS,接收端可以使用该DM-RS进行信道估计,对发送端在该repetition上传输的数据进行解调。
如图2所示,每个方框代表一个repetition,该方框中的灰色方框为表示发送端发送每个repetition对应的DM-RS时,所要使用的时域资源的位置。可以看出,发送端在相应的时域资源上发送与每个repetition对应的两个DM-RS,则接收端可以使用这两个DM-RS进行信道估计,对发送端在该repetition上传输的数据进行解调。
目前,在讨论的覆盖增强特性中,在提出在信道缓变的情况下,可以采用较少的参考信号进行重复传输,比如,采用DM-RS less技术。也就是说,发送端可以在某些repetition对应的时域资源上不发送DM-RS,因为信道缓变,该repetition对应的信道估计可以通过在前面repetition的时域资源上发送的DM-RS实现。
然而,DM-RS less技术会改变DM-RS和repetition之间的对应关系,网络设备如何指示DM-RS的位置以及终端设备如何确定DM-RS在多个repetition中的位置,仍处于空白阶段。
参阅图3,图3为本申请实施例提供的一种通信系统的结构示意图。通信系统10包括终端设备100和网络设备200。
在本申请的一个实施方式中,在图3所示的通信系统下,终端设备100确定至少两个重复传输资源中承载参考信号的至少一个第一重复传输资源,其中,该至少两个重复传输资源中存在未承载参考信号的第二重复传输资源;在进行下行传输的过程中,终端设备100在该至少一个重复传输资源上接收网络设备200发送的接收参考信号和下行信道的重复,并在该第二重复传输资源上接收该下行信道的重复;或者,在进行上行传输的过程中,终端设备100在该至少一个重复传输资源上向网络设备200发送参考信号,并在该第二重复传输资源上发送该上行信道的重复。其中,该参考信号可以为解调参考信号。
可以看出,在本实施方式中,终端设备100和网络设备200在进行重复传输的过程中,可以通过较少的参考信号进行传输,而且在这种传输模式下,终端设备可以精确的确定出重复传输资源中哪些重复传输资源承载有解调参考信号,哪些重复传输资源没有承载解调参考信号,弥补了现有技术的空白。另外,采用较少的参考信号进行重复传输,与现有的重复传输方式相比,可以节省一部分时域资源,而节省下来的时域资源可以用来传输数据,进而提高终端设备100和网络设备200之间的通信效率。
在本申请的另一个实施方式中,在图3所示的通信系统下,终端设备100确定至少两个重复传输资源中承载参考信号的至少一个第一重复传输资源,其中,该至少两个重复传输资源中还存在承载参考信号的第二重复传输资源,但是,该至少一个第一重复传输资源中的每个第一重复传输资源中用于承载参考信号的重复传输资源的数量多于该第二重复传输资源中 用于承载参考信号的重复传输资源的数量,也就是说第一重复传输资源中承载的参考信号的数量相对较多,第二重复传输资源中承载的参考信号的数量较少;由于,第一重复传输资源和第二重复传输资源上都承载有参考信号,则在进行下行传输的过程中,终端设备100在该至少一个重复传输资源上接收网络设备200发送的接收参考信号和下行信道的重复,并在该第二重复传输资源上接收网络设备200发送的接收参考信号以及该下行信道的重复;或者,在进行上行传输的过程中,终端设备100在该至少一个重复传输资源上向网络设备200发送参考信号,并在该第二重复传输资源上发送参考信号以及该上行信道的重复。
可以看出,在本申请实施例中,在进行重复传输的过程中,可以在一些重复传输资源上使用相对较少的资源承载参考信号,在一些重复传输资源上使用较多的资源承载参考信号,而且在这种传输模式下,可以精确的确定出哪些重复传输资源承载相对较多的参考信号,哪些重复传输资源承载相对较少的承载参考信号,弥补了现有技术的空白。另外,在一些重复传输资源上使用相对较少的资源承载参考信号进行重复传输,与现有的重复传输方式相比,这些重复传输资源上会节省下来一部资源用来传输数据,提高了与网络设备之间的通信效率。
参阅图4,图4为本申请实施例提供的一种参考信号的位置确定方法的流程示意图。本实施例的方法包括以下步骤:
401:终端设备确定至少两个重复传输资源中承载参考信号的至少一个第一重复传输资源,其中,所述至少两个重复传输资源中存在未承载参考信号的第二重复传输资源。
其中,重复传输资源为每个重复传输对应的时域资源,且在每个重复传输资源上进行一次重复传输,即重复传输资源和重复传输一一对应,且多次重复传输所传输的信息是相同的。由于,该至少两个重复传输资源中存在未承载参考信号的第二重复传输资源,也就是说,有部分重复传输资源上不发送参考信号。
其中,该参考信号可以为解调参考信号或者其他的参考信号。本申请不对参考信号的形式进行限定。
402:终端设备在所述至少第一重复传输资源上接收参考信号和下行信道的重复,在所述第二重复传输资源上接收所述下行信道的重复,或者,在所述至少一个第一重复传输资源上发送参考信号和上行信道的重复,在所述第二重复传输资源上发送所述上行信道的重复。
由于第一重复传输资源承载有参考信号,在进行下行传输的过程中,终端设备除了在第一重复传输资源上接收下行信道的重复,还需要接收参考信号,而在第二重复传输资源上只接收下行信道的重复。由于进行repetition传输,在每个repetition上传输的数据相同,则该终端设备在第一重复传输资源上接收的下行信道的重复和在第二重复传输资源上接收的下行信道重复相同。比如,都可以是物理下行共享信道(Physical Downlink Shared Channel,PDSCH)的重复或者物理下行控制信道(Physical Downlink Control Channel,PDCCH)的重复。
同样,由于第一重复传输资源承载有参考信号,在进行上行传输的过程中,终端设备除了在第一重复传输资源上发送上行信道的重复,还发送参考信号,而在第二重复传输资源上只发送上行信道的重复。由于进行repetition传输,在每个repetition上传输的数据相同,则该终端设备在第一重复传输资源上发送的上行信道的重复和在第二重复传输资源上发送的上行信道重复相同。比如,都可以是物理上行共享信道(Physical Uplink Shared Channel,PUSCH)的重复或者物理上行控制信道(Physical Uplink Control Channel,PUCCH)的重复。
可以看出,在本申请实施例中,终端设备和网络设备在进行重复传输的过程中,可以通过较少的参考信号进行重复传输,而且在这种传输模式下,终端设备可以精确的确定出重复传输资源中哪些重复传输资源承载有参考信号,哪些重复传输资源没有承载解调参考信号, 弥补了现有技术的空白。另外,采用较少的参考信号进行重复传输,与现有的重复传输方式相比,可以节省一部分时域资源,而节省下来的时域资源可以用来传输数据,进而提高终端设备和网络设备之间的通信效率。
在一些可能的实施方式中,在进行下行传输的过程中,终端设备在该至少一个第一重复传输资源上接收参考信号,在该第二重复传输资源上接收下行信道的重复,或者,在进行上行传输的过程中,终端设备在该至少一个第一重复传输资源上发送参考信号,在该第二重复传输资源上发送上行信道的重复。
需要说明,之所以只在第一重复传输资源上发送或者接收参考信号,可能是由于该第一重复传输资源中的部分资源被影响,而导致没有多余的资源来承载上行信道或者下行信道的重复,比如,在该第一重复传输资源被占用,只剩下一个符号可以使用的情况下,这个时候就只在该一个符号上承载参考信号。而现有技术中,在某次重复传输的重复传输资源部分资源被影响的情况下,则放弃在本次重复传输上发送或者接收参考信号。
可以看出,本实施方式中,即使某次重复传输的重复传输资源部分资源被影响,终端设备仍然可以在该重复传输资源上发送或者接收参考信号,从而为位于该重复传输资源对应的重复传输之后的其他重复传输提供参考信号,终端设备可以使用该参考信号为其他重复传输进行信道估计,提高其他重复传输的传输成功率。
在一些可能的实施方式中,可能在一个时隙(slot)上进行多个重复传输,则终端设备可以只在该slot中第一个重复传输上发送和接收参考信号,不在该slot中的其他重复传输上发送和接收参考信号。终端设备以slot为周期发送和接收参考信号,使网络设备和终端设备的信道估计更为规整,实现较为简单。其中,该slot为NR系统下的slot。可以理解,在未来更高阶的通信系统中,这里的slot就可以为时间单元,该时间单元包括协议中预先规定的多个正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)符号。
参阅图5,图5为本申请实施例提供的另一种参考信号的位置确定方法的流程示意图。该实施例中与图4所示的实施例相同的内容,此处不再重复描述。本实施例的方法包括以下步骤:
501:网络设备向终端设备发送至少两个重复传输资源的数量以及至少一个第一重复传输资源的数量。
示例性的,网络设备可以通过一条信令向终端设备发送该至少两个重复传输资源的数量以及至少一个第一重复传输资源的数量,比如,该信令可以是物理层信令或者高层信令中的一种,本申请并不对该信令进行限定。
示例性的,网络设备也可以通过不同的信令向终端设备发送该至少两个重复传输资源的数量以及至少一个第一重复传输资源的数量,比如,通过第一信令向终端设备发送该至少两个重复传输资源的数量,通过第二信令向终端设备发送至少一个第一重复传输资源的数量。其中,第一信令和第二信令可以为类型相同的信令或者类型不同的信令。比如,第一信令和第二信令都可以是高层信令或者物理层信令;再如,该第一信令为高层信令,第二信令为物理层信令,或者,该第一信令为物理层信令,第二信令为高层信令。并且,同为高层信令或者物理层信令,该第一信令和第二信令可以是相同的信令,也可以是不同的信令。因此,本申请并不对第一信令和第二信令的形式进行限定。
502:终端设备根据所述至少两个重复传输资源的数量以及所述至少一个第一重复传输资源的数量,确定所述至少一个第一重复传输资源在所述至少两个重复传输资源中的位置。
其中,确定第一重复传输资源在该至少两个重复传输资源中的位置,也就是确定在该至 少两个重复传输资源中哪个重复传输资源上承载解调参考信号。
示例性的,终端设备根据该至少两个重复传输资源的数量以及该至少一个第一重复传输资源的数量,确定该至少一个第一重复传输资源中任意两个相邻的第一重复传输资源之间的间隔;根据该任意两个相邻的第一重复传输资源之间的间隔,确定该至少一个重复传输资源在该至少两个重复传输资源中的位置。其中,该至少两个重复传输资源中的第一个重复传输资源承载有解调参考信号。
如图6所示,从该两个重复传输资源中的第一个重复传输资源开始,按照确定出的间隔从该至少两个重复传输资源中依次确定出所有第一个重复传输资源的位置。
其中,该间隔可以为任意两个相邻的第一重复传输资源之间间隔的第二重复传输资源的数量,如图6所示,该间隔为两个第二重复传输资源。另外,该间隔也可以为该两个相邻的第一重复传输资源之间间隔的重复传输资源的数量,该重复传输资源的数量包括该两个相邻的第一重复传输资源之间的第二重复传输的数量以及该两个相邻的第一重复传输资源中的一个第一重复传输资源,如图6所示,该间隔为三个重复传输资源,即两个第二重复传输资源,以及一个第一重复传输资源。后面提到的间隔均与此类似,不再叙述。
示例性的,在该间隔为任意两个相邻的第一重复传输资源之间间隔的第二重复传输资源的数量的情况下,该间隔可以通过公式(1)表示:
Figure PCTCN2021111203-appb-000001
其中,I为间隔,N为至少两个第二重复传输资源的数量,K为至少一个第一重复传输的数量,
Figure PCTCN2021111203-appb-000002
为向上取整。
在该间隔为两个相邻的第一重复传输资源之间间隔的重复传输资源的数量的情况下,该间隔可以通过公式(2)表示:
Figure PCTCN2021111203-appb-000003
其中,I为间隔,N为至少两个第二重复传输资源的数量,K为至少一个第一重复传输的数量,
Figure PCTCN2021111203-appb-000004
为向上取整。
在一些可能的实施方式中,在该至少两个重复传输资源的数量与至少一个第一重复传输资源的比值不是整数的情况下,则会导致该至少一个第一重复传输资源中的处于时域边缘位置的第一重复传输资源(比如,第一个重复传输资源或最后一个重复传输资源)所对应的重复传输的数量与该至少一个重复传输资源中其他第一重复传输资源所对应的重复传输的数量不同。
举例来说,如图6所示,前三个第一重复传输资源中每个第一重复传输资源对应三个重复传输,比如,在第一个重复传输资源上发送的参考信号可用作前三个重复传输的信道估计,而在最后一个重复传输资源上发送的解调参考信号仅用作最后一个重复传输的信道估计。因此,这种分配第一重复传输资源的方式,导致第一重复传输资源的分布不是特别均匀。应该重新设计合理的分配方式。
示例性的,可将该至少一个重复传输资源拆分成两部分,即该至少一个重复包括前m1个第一重复传输资源和后m2个第一重复传输资源。终端设备可根据该至少两个重复传输资源的数量,以及该至少一个重复传输资源的数量,分别确定该前m1个第一重复传输资源在该至少两个重复传输资源中的位置,以及该后m2个第一重复传输资源在该至少两个重复传输资源中的位置。其中,该至少两个重复传输资源中的第一个重复传输资源承载有解调参考 信号,即该前m1个第一重复传输资源中的第一个第一重复传输资源为该至少两个第一重复传输资源中的第一个重复传输资源。
其中,该前m1个第一重复传输资源中任意两个相邻的第一重复传输资源之间的第一间隔与后m2个第一重复传输资源中任意两个相邻的第一重复传输资源之间的第二间隔不同,且该前m1个第一重复传输资源中的最后一个第一重复传输资源和后m2个第一重复传输资源中的第一个第一重复传输资源之间的间隔为该第一间隔。
示例性的,终端设备根据该至少两个重复传输资源的数量和该至少一个第一重复传输资源的数量,确定m1、m2、第一间隔和第二间隔。根据第一间隔,确定该前m1个第一重复传输资源在该至少两个重复传输资源中的位置。即,终端设备从该至少两个重复传输资源中的第一个重复传输资源开始,根据该第一间隔依次确定该前m1个第一重复传输资源在该至少两个第二重复传输资源中的位置。
示例性的,在以间隔为任意两个相邻的第一重复传输资源之间间隔的重复传输资源的数量的情况下,则第一间隔为
Figure PCTCN2021111203-appb-000005
在以间隔为任意两个相邻的第一重复传输资源之间间隔的第二重复传输资源的数量的情况下,则该第一间隔为
Figure PCTCN2021111203-appb-000006
且m1可通过公式(3)表示:
Figure PCTCN2021111203-appb-000007
其中,N为该至少两个第二重复传输资源的数量,K为该至少一个第一重复传输的数量
Figure PCTCN2021111203-appb-000008
为向上取整。
根据该第一间隔,确定该前m1个第一重复传输资源在该至少两个重复传输资源中的位置。即,终端设备从该至少两个重复传输资源中的第一个重复传输资源开始,根据该第一间隔依次确定该前m1个第一重复传输资源在该至少两个第二重复传输资源中的位置。
示例性的,在以间隔为任意两个相邻的第一重复传输资源之间间隔的重复传输资源的数量的情况下,则第二间隔为
Figure PCTCN2021111203-appb-000009
在以间隔为任意两个相邻的第一重复传输资源之间间隔的第二重复传输资源的数量的情况下,则该第一间隔为
Figure PCTCN2021111203-appb-000010
且m2可通过公式(4)表示:
Figure PCTCN2021111203-appb-000011
其中,N为该至少两个第二重复传输资源的数量,K为该至少一个第一重复传输的数量
Figure PCTCN2021111203-appb-000012
为向上取整。
终端设备先根据该前m1个第一重复传输资源中最后一个第一重复传输资源的位置,以及该第一间隔确定该后m2个第一重复传输资源中第一个重复传输资源的位置;然后,从该后m2个第一重复传输资源中第一个重复传输资源开始,根据该第二间隔依次确定该后m2个第一重复传输资源在该至少两个第二重复传输资源中的位置。
举例来说,如图7所示,若重复传输资源的数量为10,第一重复传输资源的数量为4,则可确定出m1=2,第一间隔为3,因此前2个第一重传输资源之间的第一间隔为3个重复传输资源,因此,从第一个重复传输资源开始,确定出了前2个第一重复传输资源分别为该10个重复传输资源中第一个和第四个重复传输资源;也可确定出m2=2,第二间隔为2,因此,后2个第一重复传输资源之间的第二间隔为2个重复传输资源,因此,根据该第一间隔先确 定出了后2个第一重复传输资源中的第一个重复传输资源为该10个重复传输资源中的第个重复传输资源,然后,根据该第二间隔,确定出了后2个第一重复传输资源中的第二重复传输资源为该10个重复传输资源中的第九个重复传输资源。
可以看出,相比于图6中,第一重复传输资源在该至少两个重复传输资源中的分布,在第一重复传输资源数量相同的情况下,通过图7所示的分配方式,将该至少一个第一重复传输资源分成前后两部,可以让该至少一个重复传输资源中的最后一个第一重复传输资源对应两个重复传输,使第一重复传输资源在该至少两个重复传输资源中的分布更加均匀。
此外,对于上述两种确定第一重复传输资源的方式,如图8所示,可以将间隔相对较小的第一重复传输资源优先放置在该至少两个重复传输资源中的前面,相对于图6中放置第一重复传输资源中的方式来说,将图6中的最后一个第一重复传输资源放置在最前面;相对于图7中放置第一重复传输资源中的方式来说,将间隔较小的后2个第一重复传输资源放置在前面。这样,就会使该至少两个重复传输资源中的前面,第一重复传输资源的密度较高,可以在重复传输资源较少的情况下,可以拥有更多的第一重复传输资源,便于接收端进行一些更准确的估计,比如,频偏估计、统计量估计和信道估计,等等。
503:终端设备在所述至少第一重复传输资源上接收参考信号和下行信道的重复,在所述第二重复传输资源上接收所述下行信道的重复,或者,在所述至少一个第一重复传输资源上发送参考信号和上行信道的重复,在所述第二重复传输资源上发送所述上行信道的重复。
参阅图9,图9为本申请实施例提供的又一种参考信号的位置确定方法的流程示意图。该实施例中与图4和图5所示的实施例相同的内容,此处不再重复描述。本实施例的方法包括以下步骤:
901:网络设备向终端设备发送至少两个重复传输资源的数量以及标称的相邻的第一重复传输资源之间的间隔。
其中,该标称(Nominal)的相邻的第一重复传输资源之间的间隔为位于正常位置的第一重复传输资源中任意两个相邻的第一重复传输资源之间的间隔,该位于正常位置的第一重复传输资源为该至少一个第一重复传输资源中未处于时域边缘位置的第一重复传输资源。
举例来说,如图6所示,该标称的相邻的第一重复传输资源之间的间隔为前三个第一重复传输资源中任意两个相邻的第一重复传输资源之间的间隔。
同样,该间隔可以为位于正常位置的第一重复传输资源中任意两个相邻的第一重复传输资源之间的第二重复传输资源的数量,也可以为该任意两个相邻的第一重复传输资源之间的重复传输资源的数量,该重复传输资源的数量包括该任意两个相邻的第一重复传输资源之间的第二重复传输资源的数量以及该任意两个相邻的第一重复传输资源中的一个重复传输资源。
902:终端设备根据所述至少两个重复传输资源的数量以及所述标称的相邻的第一重复传输资源之间的间隔,确定所述至少一个第一重复传输资源在所述至少两个重复传输资源中的位置。
示例性的,终端设备将该标称的相邻的第一重复传输资源之间的间隔作为该至少一个第一重复传输资源中任意两个相邻的第一重复传输资源之间的间隔。因此,终端设备可根据该至少两个重复传输资源的数量以及该任意两个相邻的第一重复传输资源之间的间隔,确定该至少一个第一重复传输在该至少两个重复传输资源中的位置。其中,具体确定至少一个第一重复传输的位置,可参见步骤502中的内容,不再叙述。
示例性的,终端设备根据该至少两个重复传输资源的数量以及该标称的相邻的第一重复 传输资源之间的间隔,确定该至少一个重复传输资源的数量。
示例性的,在标称的相邻的第一重复传输资源之间的间隔为该位于正常位置的第一重复传输资源中任意两个相邻的第一重复传输资源之间的第二重复传输资源的数量的情况下,则至少一个重复传输资源的数量可通过公式(5)表示:
Figure PCTCN2021111203-appb-000013
其中,K为至少一个重复传输资源的数量,N为至少两个重复传输资源的数量,L为标称的相邻的第一重复传输资源之间的间隔。
示例性的,在该间隔为该任意两个相邻的第一重复传输资源之间的重复传输资源的数量的情况下,至少一个重复传输资源的数量可通过公式(6)表示:

其中,K为至少一个重复传输资源的数量,N为至少两个重复传输资源的数量,L为标称的相邻的第一重复传输资源之间的间隔。
同样,在确定出该至少一个重复传输资源的数量后,可将该至少一个第一重复传输资源拆分成前后两部分,即该至少一个第一重复传输资源包括前n1个第一重复传输资源和后n2个第一重复传输资源。因此,与步骤502中类似,终端设备可根据该至少两个重复传输资源的数量以及该至少一个重复传输资源的数量,分别确定该前n1个第一重复传输资源在该至少两个重复传输资源中的位置,以及该后n2个第一重复传输资源在所述至少两个重复传输资源中的位置,具体确定第一重复传输资源的位置,可参照步骤502中的内容,不再叙述。
其中,该至少两个重复传输资源中的第一个重复传输资源承载有解调参考信号,即该前n1个第一重复传输资源中的第一个第一重复传输资源为该至少两个第一重复传输资源中的第一个重复传输资源。此外,该前n1个第一重复传输资源中任意两个相邻的第一重复传输资源之间的第三间隔与后n2个第一重复传输资源中任意两个相邻的第一重复传输资源之间的第四间隔不同,且该前n1个第一重复传输资源中的最后一个第一重复传输资源和后n2个第一重复传输资源中的第一个第一重复传输资源之间的间隔为该第三间隔。
903:终端设备在所述至少第一重复传输资源上接收参考信号和下行信道的重复,在所述第二重复传输资源上接收所述下行信道的重复,或者,在所述至少一个第一重复传输资源上发送参考信号和上行信道的重复,在所述第二重复传输资源上发送所述上行信道的重复。
参阅图10,图10为本申请实施例提供的又一种参考信号的位置确定方法的流程示意图。该实施例中与图4、图5和图9所示的实施例相同的内容,此处不再重复描述。本实施例的方法包括以下步骤:
1001:网络设备向终端设备发送至少两个重复传输资源的数量以及标称的相邻的第一重复传输资源之间的间隔。
1002:网络设备向终端设备发送第一消息,所述第一消息用于确定所述至少两个重复传输资源中的重复传输资源i被取消。
其中,重复传输资源i可以为该至少两个重复传输资源中的任意一个重复传输资源。在实际应用中,可能会有多个重复传输资源被取消。本申请中仅以一个重复传输资源被取消为例进行举例说明,其他被取消的情况可以参照该一个重复传输资源被取消的情况,不再叙述。
其中,该重复传输资源i被取消,也就是说与该重复传输资源i对应的重复传输被取消。
在终端设备还未来得及根据至少两个重复传输资源的数量以及标称的相邻的第一重复传输资源之间的间隔,确定第一重复传输资源的位置之前,网络设备就已经向终端设备发送第 一消息,通过第一消息指示终端设备在该至少两个重复传输之间有高优先级的传输,终端设备需要中断重复传输资源i上的重复传输。从终端设备的角度来说,在确定第一重复传输资源的位置之前,终端设备就提前预知到该至少两次重复传输资源中有部分重复传输资源被取消。当然,在实际应用中,终端设备也有可能无法提前预知该至少两次重复传输资源中有部分重复传输资源被取消,关于终端设备在哪些场景下可以提前预知重复传输资源被取消,以及在哪些场景下无法提前预知重复传输资源被取消,后面进行详细的介绍,在此不做过多描述。
1003:终端设备根据所述至少两个重复传输资源的数量、所述标称的相邻的第一重复传输资源之间的间隔以及所述重复传输资源i,确定所述至少一个第一重复传输资源在所述至少两个重复传输资源中的位置。
由于终端设备提前预知到重复传输资源i被取消,对于上行传输来说,则可能导致与该重复传输资源i相邻的两个重复传输资源对应的发送相位不连续或者发送功率的差值不在网络设备配置的第一区域范围内,这也就导致终端设备进行两个重复传输时所使用的信道不同,则后面的重复传输不能使用前面的参考信号进行信道估计。
其中,该第一区域范围可以为(q1,q2),q1为负数,q2为正数,且q1和q2的绝对值可以相等或不相等。也就是说,若与该重复传输资源i相邻的两个重复传输资源中后一个重复传输资源对应的发送功率,是大于前一个重复传输资源的,则网络设备所允许发送功率最大的差值为q2,如果差值超过该q2,终端设备可以调整增益档位,进而使用不同的信道进行重复传输;若与该重复传输资源i相邻的两个重复传输资源中后一个重复传输资源对应的发送功率,是小于前一个重复传输资源的,则网络设备所允许发送功率最小的差值为q1,如果差值小于q1,终端设备可以调整增益档位,进而使用不同的信道进行重复传输。
因此,如果终端设备根据图5或图9所示的实施例确定第一重复传输资源的位置,由于重复传输资源i被取消,则可能导致位于该重复传输资源i之后的几个重复传输没有参考信号可以使用,也就导致终端设备需要存储在这期间接收到的数据,增大了终端设备的存储。
示例性的,如图11所示,按照图5或图9所示的实施例确定第一重复传输资源的位置,则终端设备可以确定出第一个重复传输资源、第六个重复传输资源以及第十一个重复传资源承载有参考信号。若第七个重复传输资源不被取消,则第六个-第十个重复传输都可以使用在第六个重复传输资源发送的参考信号进行信道估计。由于第七个重复传输资源被取消,导致第六个重复传输和第八个重复传输使用的信道不同,因此,第八个重复传输不能使用在第六个重复传输资源上发送的参考信号进行信道估计,这样也就导致终端设备需要存储在第八个-第十个重复传输之间所接收到的数据,增大了终端设备的存储。
此外,还有可能的是,如果按照图5或图9所示的实施例来确定第一重复传输资源的位置,可能导致确定出的重复传输资源i是一个第一重复传输资源,则后面的重复传输只能使用在位于重复传输资源i之前的第一重复传输资源上发送的参考信号进行信道估计。但是这个第一重复传输资源,可能与后面的重复传输的距离较远,因为信道的变化,导致对后面的信道估计的质量可能较差。
因此,终端设备根据该至少两个重复传输资源的数量、标称的相邻的第一重复传输资源之间的间隔以及重复传输资源i,确定至少两个重复传输资源中第一重复传输资源的位,使第一重复传输资源的分布更加合理。
示例性的,终端设备确定该至少两个重复传输资源中位于该重复传输资源i之后的未被取消的重复传输资源的第一数量;根据该第一数量和该标称的相邻的第一重复传输资源之间 的间隔,确定位于该重复传输资源i之后的未被取消的重复传输资源中第一重复传输资源的位置。即,相当于把位于该重复传输资源i之后的未被取消的重复传输资源看成多个新的重复传输资源,并根据第一数量以及标称的间隔确定该多个新的重复传输资源中第一重复传输资源的位置,其确定方式可参照图9所述的实施例,不再叙述。
示例性的,终端设备确定该至少两个重复传输资源中位于该重复传输资源i之前的未被取消的重复传输资源的第二数量;根据该第二数量和该标称的相邻的第一重复传输资源之间的间隔,确定位于该重复传输资源i之前的未被取消的重复传输资源中第一重复传输资源的位置。即相当于把位于该重复传输资源i之前的未被取消的重复传输资源看成多个新的重复传输资源,并根据第二数量以及标称的间隔确定该多个新的重复传输资源中第一重复传输资源的位置,其确定方式可参照图9所述的实现方式,不再叙述。
示例性的,如图12所示,将重复传输资源i考虑在内来确定第一重复传输资源的位置,可以确定出第一个重复传输资源、第四个重复传输资源、第八个重复传输资源以及第十二重复传输资源为第一重复传输资源。可以看出,在被取消的第七个重复传输资源之后的第一个未被取消的重复传输资源,即第八个重复传输资源上,直接承载了参考信号,终端设备可以正常解调出在第八个重复传输-第十一个重复传输之间接收的数据,无需增加终端设备的存储。
需要说明的是,重复传输资源i被取消,与其相邻的两个重复传输资源对应的发送相位可能还是连续或者该相邻的两个重复传输资源对应的发送功率也在该网络设备配置的第一区域范围内,则终端设备在进行该两个重复传输资源对应的两个重复传输的过程中,可使用相同的信道。这样相当于重复传输资源i对确定该至少一个重复传输资源的位置并无影响,因此,终端设备可直接根据该至少两个重复传输资源的数量以及该标称的相邻的第一重复传输资源之间的间隔,确定该至少一个重复传输资源在该至少两个重复传输中的位置,其具体的实现方式可参照图9所述的实现方式,不再叙述。
此外,对于发送相位连续或者发送功率在该网络设备配置的第一区域范围内,可以由终端设备自主确定,也可以由网络设备指示。在由终端设备自主确定的情况下,可通该重复传输资源i被取消的时长来确定,如果该时长小于阈值,则确定可以使用图9的方式直接确定第一重复传输资源的位置,否则,使用图10所示的方式来确定第一重复传输资源的位置,本申请并不对终端设备的实现方式进行限定;在由网络设备指示的情况下,可通过该第一消息本身来实现,比如,若网络设备向终端设备发送该第一消息,则说明发送相位连续或者发送功率在该网络设备配置的第一区域范围内,若网络设备向终端设备发送其他的消息来指示重复传输资源i被取消,则说明发送相位不连续或者发送功率不在该网络设备配置的第一区域范围内;当然,也可以通过额外的消息信令,直接指示发送相位是否连续或者发送功率是否在该网络设备配置的第一区域范围内。本申请并不对网络设备的指示方式进行限。
1004:终端设备在所述至少第一重复传输资源上接收参考信号和下行信道的重复,在所述第二重复传输资源上接收所述下行信道的重复,或者,在所述至少一个第一重复传输资源上发送参考信号和上行信道的重复,在所述第二重复传输资源上发送所述上行信道的重复。
参阅图13,图13为本申请实施例提供的又一种参考信号的位置确定方法的流程示意图。该实施例中与图4、图5、图9和图10所示的实施例相同的内容,此处不再重复描述。本实施例的方法包括以下步骤:
1301:终端设备确定至少两个重复传输资源中承载参考信号的至少一个第一重复传输资源,其中,所述至少两个重复传输资源中存在未承载参考信号的第二重复传输资源。
其中,确定第一重复传输资源的位置,可以根据至少两个重复传输资源的数量以及至少一个重复传输的数量实现或者,根据至少两个重复传输资源的数量以及标称的相邻的第一重复传输资源之间的间隔实现,可参照上述图5或图9所示实施例中的实现过程,不再叙述。
当然,终端设备在确定至少两个重复传输资源中承载参考信号的至少一个第一重复传输资源之前,可能接收到了网络设备发送的第一消息,根据该第一消息确定重复传输资源i被取消,然后,根据该重复传输资源i、至少两个重复传输资源的数量以及标称的相邻的第一重复传输资源之间的间隔,确定第一重复传输资源的位置。具体实现方式,可参见图10的实施例所示的过程。
1302:网络设备向终端设备发送第二消息,所述第二消息用于确定所述至少两个重复传输资源中的重复传输资源j被取消。
也就是说,在终端设备确定好第一重复传输资源在该至少两个重复传输资源中的位置后,向终端设备发送第二消息,通过该第二消息指示该终端设备有高优先级的传输进行,进而确定该至少两个重复传输资源中的重复传输资源j被取消。从终端设备角度来说,终端设备无法提前预知哪个重复传输资源被取消。
1303:终端设备根据所述重复传输资源j,调整所述至少一个第一重复传输资源在所述至少两个重复传输资源中的位置。
终端设备在接收到第二消息之前,已经确定好了第一重复传输资源的位置,但是由于重复传输资源j被取消,导致与重复传输资源j相邻的两个重复传输可能所使用的信道不同;也有可能是,该重复传输资源j本身就是一个第一重复传输资源,重复传输资源j被取消,则导致后面的重复传输只能使用在位于重复传输资源j之前的第一重复传输资源上发送的参考信号进行信道估计。但是这个第一重复传输资源,可能与后面的重复传输的距离较远,因为信道的变化,导致对后面的信道估计的质量可能较差。因此,可以重新调整第一重复传输资源的位置。
另外,为了避免增加接收端的存储,则位于重复传输资源j之后的未被取消的重复传输资源中的第一个重复传输资源上承载有参考信号。
示例性的,终端设备确定至少两个重复传输资源中位于重复传输资源j之后的未被取消的重复传输资源的第三数量,以及位于重复传输资源j之后的未被取消的第一重复传输资源的第四数量;然后,根据该第三数量和第四数量确定位于重复传输资源j之后的未被取消的重复传输资源中第一重复传输资源的位置,其中,位于该重复传输资源j之后的未被取消的重复传输资源中的第一个重复传输资源承载有参考信号。
后面详细介绍根据该第三数量和第四数量,确定位于重复传输资源j之后的未被取消的重复传输资源中第一重复传输资源的位置的确定过程,在此不做过多描述。
由于终端设备无法提前预知哪个重复传输资源被取消,且终端设备准备数据是需要一段时间的,因此,终端设备要想调整位于重复传输资源j之后的未被取消的重复传输资源中第一重复传输资源的位置,则可以保证终端设备来的及准备数据。故终端设备先确定第一时间间隔是否大于第一阈值,在确定该第一时间间隔大于或等于第一阈值的情况下,再确定该第三数量和该第四数量,以调整第一重复传输资源的位置。
其中,该第一阈值是根据该终端设备进行数据传输的准备时长确定的,该第一时间间隔为第一时间和第二时间之间的时间间隔,该第一时间为该重复传输资源j之后的未被取消的重复传输资源的开始时间,该第二时间为该终端设备接收到该第二消息的结束时间,且该第二时间是晚于该第一时间。
此外,在确定该第一时间间隔小于该第一阈值的情况下,则终端设备接收到第二消息的时间太晚,换句话说,终端设备接收到该第二消息的时间距离该重复传输资源之后的未被取消的重复传输资源的开始时间太近,可能会导致终端设备来不及为位于重复传输资源j之后的第一个重复传输资源准备数据。因此,即使将第一重复传输资源的位置进行了调整,使位于重复传输资源j之后的第一个重复传输资源上承载参考信号,这个参考信号也是没有作用的。在这种情况下,终端设备可以不调整第一重复传输资源的位置,按照之前确定好的第一重复传输资源的位置进行重复传输;或者,放弃位于重复传输资源j之后的重复传输。
示例性的,如图14所示,假设第一阈值为T1,且第七个重复传输资源被取消,位于该第七个重复传输资源之后的第一重复传输资源的开始时间为t2;若终端设备是在t4之前接收到第二消息,则终端设备来得及为第八个重复传输资源准备数据,这个时候可以重新确定位于第七个重复传输资源之后的重复传输资源中第一重复传输资源的位置,使第八个重复传输资源上承载有参考信号。若终端设备是在t4时间之后接收到第二消息,则终端设备来不及为第八个重复传输资源准备数据,则终端设备可以采用原本调整前确定好的第一重复传输资源进行重复传输,或者放弃第七个重复传输资源之后的重复传输资源。
需要说明,终端设备该第一时间间隔是否大于该第一阈值的方式,可由网络设备来实现。具体地,网络设备自主决策当前是否能对位于重复传输资源j之后的未被取消的重复传输资源中第一重复传输资源的位置进行调整,如果能,则向终端设备发送第二消息,通过该第二消息本身向该终端设备指示能对位于重复传输资源j之后的未被取消的重复传输资源中第一重复传输资源的位置进行调整;或者,通过其他消息指示是否能对位于重复传输资源j之后的未被取消的重复传输资源中第一重复传输资源的位置进行调整。本申请不对网络设备的实现方式进行限定。
另外,重复传输资源j被取消的取消也会导致位于该重复传输资源j之前的未被取消的重复传输资源中第一重复传输资源的分配不再均匀。因此,终端设备可以调整位于该重复传输资源j之前的未被取消的重复传输资源中第一重复传输资源的位置。
可以理解,虽然终端设备无法提前预知重复传输资源j被取消,但是如果终端设备很早就接收到了第二消息,而且这个时候若终端设备还未进行一次重复传输,则可以调整位于该重复传输资源j之前的未被取消的重复传输资源中第一重复传输资源的位置。
示例性的,确定至少两个重复传输资源中位于重复传输资源j之前的未被取消的重复传输资源的第五数量,以及位于重复传输资源j之前的未被取消的第一重复传输资源的第六数量;根据第五数量和第六数量,确定位于重复传输资源j之前的未被取消的重复传输资源中第一重复传输资源的位置,其中,位于重复传输资源j之前的未被取消的重复传输资源中的第一个重复传输资源承载有解调参考信号。
后面详细介绍,根据该第五数量和该第六数量,确定位于重复传输资源j之前的未被取消的重复传输资源中第一重复传输资源的位置,在此不做过多描述。
类似的,终端设备要想调整位于重复传输资源j之前的未被取消的第一重复传输资源的位置,则先确定第二时间间隔是否大于第一阈值,若确定该第二时间间隔大于或等于第一阈值,再确定该第五数量和该第六数量,以调整位于重复传输资源j之前的未被取消的重复传输资源中的第一重复传输资源的位置。
其中,该第一阈值是根据该终端设备进行数据传输的准备时长确定的,该第二时间间隔为第二时间和第三时间之间的时间间隔,该第二时间为终端设备接收到该第二消息的结束时间,且该第二时间早于该第三时间,该第三时间为该至少两个重复传输资源中的第一个重复 传输资源的开始时间。
可以理解,若该第二时间间隔小于该第一阈值,如果重新调整位于重复传输资源j之前的未被取消的第一重复传输资源的位置,则终端设备无法为调整位置后的重复传输资源准备数据。因此,这个时候不能再去调整位于重复传输资源j之前的未被取消的第一重复传输资源的位置,可通过之前确定好的第一重复传输资源的位置进行重复传输。
示例性的,如图14所示,由于第七个重复传输资源被取消,导致位于该第七个重复传输资源之前的重复传输资源中第一重复传输资源的分布不再均匀。比如,第一个重复传输资源对应五个重复传输资源,而第二重复传输资源对应一个重复传输资源。因此,若终端设备是在t3之前接收到该第二消息,则从接收到该第二消息的结束时间到第一个重复传输资源的开始时间之间的间隔大于第一阈值,也就说,终端设备还来得及给第一个重复传输资源准备数据,这样调整了位于重复传输资源j之前的未被取消的重复传输资源中第一重复传输资源的位置,仍然有充足的时间准备数据,因此可调整位于重复传输资源j之前的未被取消的第一重复传输资源的位置,使第一重复传输资源的分布更加均匀。若终端设备是在t3~t1之间接收到了该第二消息,由于来不及为第一个重复传输资源准备数据,这个时候就不能再去调整位于重复传输资源j之前的未被取消的第一重复传输资源的位置,可使用调整前的重复传输资源进行重复传输。当然,若终端设备是在t1~t4之间接收到该第二消息,则位于重复传输资源j之前的部分重复传输资源已被消耗了,这个时候也更不能去调整位于重复传输资源j之前的未被取消的第一重复传输资源的位置。
需要说明,终端设备该第二时间间隔是否大于该第一阈值的方式,可由网络设备来实现。具体地,网络设备自主决策当前是否能对位于重复传输资源j之前的未被取消的重复传输资源中第一重复传输资源的位置进行调整,如果能,则向终端设备发送第二消息,通过该第二消息本身向该终端设备指示能对位于重复传输资源j之前的未被取消的重复传输资源中第一重复传输资源的位置进行调整;或者,通过其他消息指示是否能对位于重复传输资源j之前的未被取消的重复传输资源中第一重复传输资源的位置进行调整。本申请不对网络设备的实现方式进行限定。
下面详细介绍如何确定位于重复传输资源j前后未被取消的重复传输资源中的第一重复传输资源的位置。
示例性的,将该第五数量和第六数量,分别当做新的重复传输资源的数量和新的第一重复传输资源的数量,并根据该新的重复传输资源的数量和新的第一重复传输资源的数量,确定位于重复传输资源j之前的未被取消的重复传输资源中的第一重复传输资源的位置。
示例性的,若
Figure PCTCN2021111203-appb-000015
将该第三数量作为新的重复传输资源的数量,将该第六数量作为新的第一重复传输资源的数量,并根据该新的重复传输资源的数量以及该新的第一重复传输资源的数量,确定位于重复传输资源j之后的未被取消的重复传输资源中的第一重复传输资源的位置。其中,KK2为该第四数量,N2为该第三数量;若
Figure PCTCN2021111203-appb-000016
将该第三数量作为新的重复传输资源的数量,将该第六数量加一之后作为新的第一重复传输资源的数量,终端设备根据该新的重复传输资源的数量以及该新的第一重复传输的数量,确定位于重复传输资源j之后的未被取消的重复传输资源中的第一重复传输资源的位置。
其中,根据重复传输的数量以及第一重复传输的数量,确定第一重复传输资源的位置的实现方式可参见上述过程,不再叙述。
此外,若终端设备接收到网络设备发送的标称的相邻的第一重复传输资源之间的间隔, 则可只获取位于重复传输资源j之后的未被取消的重复传输资源的第三数量;然后,根据该第三数量以及该标称的相邻的第一重复传输资源之间的间隔,确定位于重复传输资源j之前的未被取消的重复传输资源中第一重复传输资源的位置。当然,也可只获取位于重复传输资源j之前的未被取消的重复传输资源的第五数量;然后,根据该第五数量以及该标称的相邻的第一重复传输资源之间的间隔,确定位于重复传输资源j之前的未被取消的重复传输资源中第一重复传输资源的位置。
其中,根据重复传输资源的数量以及标称的相邻的第一重复传输资源之间的间隔,确定第一重复传输资源的位置的方式,可参见上述实现过程,不再叙述。
在一些可能的实施方式中,虽然重复传输资源j被取消,但是被取消后的发送相位也有可能连续或者发送功率也在网络设备配置的第一范围内,这样终端设备也就无需去调整第一重复传输资源的位置。因此,在确定距离所述重复传输资源j之前的最近一个未被取消的重复传输资源和之后的最近一个未被取消的重复传输资源的发送相位不连续的情况下或者在确定距离所述重复传输资源j之前的最近一个未被取消传输的重复传输资源和之后的最近一个未被取消传输的重复传输资源的发送功率差异不在所述网络设备配置的第一区域范围内的情况下,才去调整该至少一个第一重复传输资源在该至少两个重复传输资源中的位置,否则,不用去调整该至少一个第一重复传输资源在该至少两个重复传输资源中的位置。
需要说明,确定发送相位是否连续或者发送功率是否不在第一区域范围内,可以由网络设备来实现。可以由终端设备自主确定,也可以由网络设备指示。具体地,在由终端设备自主确定的情况下,可通该重复传输资源j被取消的时长来确定,如果该时长小于阈值,则确定发送相位连续,否则发送相位不连续;在由网络设备指示的情况下,可通过该第二消息本身来实现,比如,若网络设备向终端设备发送该第二消息,则说明发送相位连续,若网络设备向终端设备发送其他的消息来指示重复传输资源j被取消,则说明发送相位不连续或者发送功率不在该网络设备配置的第一区域范围内;当然,也可以通过其他的消息,直接指示发送相位是否连续或者发送功率是否在该网络设备配置的第一区域范围内。本申请并不对网络设备的指示方式进行限。
1304:终端设备在所述至少第一重复传输资源上接收参考信号和下行信道的重复,在所述第二重复传输资源上接收所述下行信道的重复,或者,在所述至少一个第一重复传输资源上发送参考信号和上行信道的重复,在所述第二重复传输资源上发送所述上行信道的重复。
此外,在信道缓变的情况下,还提出了另外一种DM-RS less技术,该DM-RS less技术主要思想是发送端在某些repetition对应的重复传输资源上发送高密度DM-RS,在某些repetition对应的重复传输资源上发送低密度DM-RS,这样接收端可以使用高密度DM-RS进行精确的信道估计,使用低密度DM-RS进行粗略的信道估计,结合高密度DM-RS和低密度DM-RS进行联合信道估计,以满足不同的信道估计需求。示例性的,高密度DM-RS与低密度DM-RS相比,用于承载高密度DM-RS的重复传输资源的数量多于用于承载低密度DM-RS的重复传输资源的数量,也可以理解为高密度DM-RS的在重复传输资源上传输的DM-RS的数量多于低密度DM-RS在重复传输资源上传输的DM-RS的数量。
如图15所示,发送端可以在第1和第3个repetition对应的重复传输资源上发送高密度DM-RS,在第2和第4个repetition对应的重复传输资源发送低密度DM-RS。
然而,这种DM-RS less技术会造成某些repetition对应的重复传输资源上承载的是高密度DM-RS,某些repetition对应的重复传输资源上承载的是低密度DM-RS。因此,这种DM-RS less技术也会改变DM-RS和repetition之间的对应关系,网络设备如何指示高密度DM-RS的 位置、低密度DM-RS的位置,以及终端设备如何确定高密度DM-RS、低密度DM-RS在多个repetition中的位置,目前也处于空白阶段。
因此,为了上述DM Less技术带来的无法确定出高密度DM-RS、低密度DM-RS在多个repetition中的位置的问题,本申请实施例提供了一种参考信号位置的确定方法。
参阅图16,图16为本申请实施例提供了另外一种参考信号位置的确定方法的流程示意图。该方法包括以下步骤:
1601:终端设备确定至少两个重复传输资源中承载参考信号的至少一个第一重复传输资源,其中,至少两个重复传输资源中存在承载参考信号的第二重复传输资源,且至少一个第一重复传输资源中的每个第一重复传输资源中用于承载参考信号的重复传输资源的数量多于第二重复传输资源中用于承载参考信号的重复传输资源的数量。
其中,确定至少两个重复传输资源中承载参考信号的至少一个第一重复传输资源的方式,与上述图4、图5、图9以及图10中所示出的确定至少一个第一重复传输资源的方式类似,不再叙述。
一般来说,任意两个第一重复传输资源中用于承载参考信号的重复传输资源的数量是相同的,任意两个第二重复传输资源中用于承载参考信号的重复传输资源的数量也是相同的。当然,在实际应用中,也可以将任意两个第一重复传输资源中用于承载参考信号的重复传输资源的数量设计为不同的,以及将任意两个第二重复传输资源中用于承载参考信号的重复传输资源的数量设计为不同的,但是,任意一个第一重复传输资源中用于承载参考信号的重复传输资源的数量多于第二重复传输资源中用于承载参考信号的重复传输资源的数量。
进一步地,用于承载DM-RS的重复传输资源包括频域资源和时域资源。因此,用于承载高密度DM-RS的重复传输资源的数量多于用于承载低密度DM-RS的重复传输资源的数量主要包括以下几种示例:
示例1:若用于承载高密度DM-RS的频域资源的数量和用于承载低密度DM-RS的频域资源的数量相同,则用于承载高密度DM-RS的OFDM符号的数量多于用于承载低密度DM-RS的OFDM符号的数量;
示例2:若用于承载高密度DM-RS的时域资源的数量和用于承载低密度DM-RS的时域资源的数量相同,则用于承载高密度DM-RS的资源单元(resource element,RE)的数量多于用于承载低密度DM-RS的RE的数量;
示例3:用于承载高密度DM-RS的OFDM符号的数量多于用于承载低密度DM-RS的OFDM符号的数量,且用于承载高密度DM-RS的RE的数量多于用于承载低密度DM-RS的RE的数量。
因此,对于本申请来说,第一重复传输资源中用于承载参考信号的重复传输资源的数量多于第二重复传输资源中用于承载参考信号的重复传输资源的数量主要包括以下几种情况:
情况1:若第一重复传输资源中用于承载参考信号的时域资源的数量与第二重复传输资源中用于承载参考信号的时域资源的数量相同,则第一重复传输资源中用于承载参考信号的OFDM符号的数量多于第二重复传输资源中用于承载参考信号的OFDM符号的数量;
情况2:若第一重复传输资源中用于承载参考信号的频域资源的数量与第二重复传输资源中用于承载参考信号的频域资源的数量相同,则第一重复传输资源中用于承载参考信号的RE的数量多于第二重复传输资源中用于承载参考信号的RE的数量;
情况3:第一重复传输资源中用于承载参考信号的OFDM符号的数量多于第二重复传输资源中用于承载参考信号的OFDM符号的数量,且第一重复传输资源中用于承载参考信号的 RE的数量多于第二重复传输资源中用于承载参考信号的RE的数量。
1602:终端设备在所述至少一个第一重复传输资源上接收参考信号和下行信道的重复,在第二重复传输资源上接收下行信道的重复,或者,终端设备在至少一个第一重复传输资源上发送参考信号和上行信道的重复,在第二重复传输资源上发送上行信道的重复。
可以看出,在本申请实施例中,在进行重复传输的过程中,可以在一些重复传输资源上使用相对较少的资源承载参考信号,无需在每个重复传输资源上都承载较多的参考信号,而且在这种传输模式下,可以精确的确定出哪些重复传输资源承载相对较多的参考信号,哪些重复传输资源承载相对较少的承载参考信号,弥补了现有技术的空白。另外,在一些重复传输资源上使用相对较少的资源承载参考信号进行重复传输,与现有的重复传输方式相比,这些重复传输资源上会节省下来一部资源用来传输数据,提高了与网络设备之间的通信效率。
应理解的是,针对本实施例中的DM-RS Less技术,在终端设备确定出高密度DM-RS的位置以及低密度的DM-RS的位置之后,也可能存在重复传输资源被取消的情况,比如,重复传输资源i被取消,由于重复传输资源被取消,可能导致位于重复传输资源i之后的重复传输没有高密度DM-RS进行精确的信道估计,比如,位于该重复传输资源i之后的几个重复传输资源为第二重复传输资源,此时,只能使用第二重复传输资源承载的低密度DM-RS进行粗略的信道估计,如果此时接收端想要进行精确的信道估计,则需要等待下一个承载有高密度DM-RS的重复传输资源的到来,在等待期间,需要将等待期间接收到的重复传输的数据进行存储,增大了接收端的存储。因此,与上述图10中示出的方法类似,在重复传输资源被取消的情况下,可以对第一重复传输资源以及第二重复传输资源的位置进行调整,以减少接收端的存储,其调整方式与图10中示出的调整方式类似,也就是说,分别将图16对应的实施例中提到的第一重复传输资源作为图10中的第一重复传输资源,将第二重复传输资源作为图10中的第二重复资源,不再叙述。
下面介绍在一种特殊的高优先级传输的场景下,如何确定第一重复传输资源的位置。
具体地,在高优先级传输为上行configured grant传输的情况下,为上行configured grant传输预留上行资源,但是,不确定终端设备是否会进行上行传输。因此,在使用DM-RS less技术进行重复传输的过程中,可以通过另外一种处理对上行configured grant传输进行处理。该另一种处理方式包括以下两种处理方式:
示例性的,若终端设备接收到网络设备指示的高优先级传输为上行configured grant传输的情况下,确定该上行configured grant传输不能取消重复传输,也就是说上行configured grant传输不会取消任何一个重复传输资源。因此,终端设备可以按照图5或图9所示的实施例确定第一重复传输资源的位置。
示例性的,若终端设备有机会进行上行传输,则按照图10或图13所示的实施例确定第一重资源的位置;若终端设备没有机会进行上行传输,则按照图5或图9所示的实施例确定第一重复传输资源的位置。
最后,参阅表1,表1详细列举了终端设备是否能提前预知重复传输资源被取消的场景,以在重复传输资源被取消的情况下,终端设备的发送相位是否连续的场景。
