Description
本发明涉及信息处理技术领域,尤其涉及一种数据传输方法、终端设备、网络设备、芯片、计算机可读存储介质、计算机程序产品以及计算机程序。
在免授权频谱上,通信设备(例如网络设备)在进行信号发送前,需要对免授权频谱上的信道进行先听后说LBT检测。如果LBT成功,通信设备可以进行信号发送;如果LBT失败,通信设备不能进行信号发送。由于发射设备进行信号发送时具有不确定性,接收设备在接收时,需要进行盲检测,判断发射设备是否成功发送信号。为了保证公平性,在一次传输中,通信设备使用免授权频谱的信道进行信号传输的时长不能超过最大信道占用时间(Maximum Channel Occupation Time,MCOT)。
目前新无线(NR,New Radio)系统规定一个时隙(slot)包含14个时域符号,一个PDSCH/PUSCH只能占用一个slot内的时域符号进行传输。终端最多支持16个HARQ进程。在NR-U系统中为了尽可能避免LBT检测,来自一个发送端的数据应该尽可能连续发送。然而,在使用较大的子载波间隔进行传输时,如图1所示,目前通常采用15Kz子载波间隔、10个HARQ进程,但是采用60kHz为子载波间隔时,一个COT内最多可包括40个HARQ进程。此时,若依然沿用目前的HARQ进程进行TB传输的设计,则会影响传输效率。

实施例一、
本发明实施例提供了一种数据传输方法,应用于终端设备,如图3所示,包括:
步骤301:获取第一时域资源长度;其中,所述第一时域资源长度与当前终端设备传输一个传输块(Transport Block,TB)所采用的子载波间隔相关;
步骤302:接收网络侧发来的配置信息,根据所述配置信息确定采用第一物理资源传输目标TB;其中,所述第一物理资源的时间长度不大于所述第一时域资源长度。
本发明实施例中,所述第一时域资源长度可以理解为用于确定所述终端设备传输一个传输块TB所能使用的时域资源的最大值。
其中,所述第一时域资源长度可以包括以下几种表示方式:
传输一个TB所能占用的TTI(传输时间间隔)的最大数量;
传输一个TB所能占用的时隙slot的最大数量。
传输一个TB所能占用的时域符号的最大数量。
具体地,可以通过RRC信令预配置时域资源列表实现,即列表中包含的最大时域符号数量。
基于前述方案下面针对如何获取第一时域资源长度进行说明:
本申请可以提供两种方式一种为通过网络侧发送的信息确定第一时域资源长度;另一种为由终端设备自身确定第一时域资源长度。
具体的,
方式一、接收网络侧发送的第一信息;其中,所述第一信息用于指示第一时域资源长度。
相应的,终端设备可以根据第一信息中指示的内容直接确定第一时域资源长度。
进一步地,所述第一时域资源长度不大于第一阈值;其中,所述第一阈值的取值与当前终端设备传输一个TB所采用的子载波间隔相关。也就是说,第一时域资源长度与第一阈值相关,并且第一阈值与传输TB的子载波间隔相关。
其中,所述第一阈值的取值与子载波间隔之间的对应关系由协议确定,或者,所述第一阈值的取值根据传输一个TB所使用的子载波间隔以及参考子载波间隔确定。
关于第一阈值的取值和子载波间隔之间的对应关系,可以根据预设的表格来确定,比如,如下表1或表2所示:
| 子载波间隔 | 第一阈值(TTI/slot数量) |
| 15kHZ | 1 |
| 30kHz | 2 |
| 60kHz | 4 |
| 120kHz | 8 |
表1
| 子载波间隔 | 第一阈值(时域符号数量) |
| 15kHZ | 14 |
| 30kHz | 2*14 |
| 60kHz | 4*14 |
| 120kHz | 8*14 |
表2
具体来说,当第一时域资源长度用于表征传输一个TB所能占用的TTI(传输时间间隔)的最大数量或者表征传输一个TB所能占用的时隙slot的最大数量时,可以通过前述表1来确定第一阈值和子载波间隔之间的关系,比如,当子载波间隔为30KHz时,第一阈值可以为2个TTI或者2个时隙,其他的子载波间隔也根据表1来确定,这里不再进行赘述;
当第一时域资源长度用于表征传输一个TB所能占用的时域符号数量时,可以通过前述表2来确定子载波间隔和第一阈值之间的关系,比如,当子载波间隔为60KHz时,对应的第一阈值可以为4*14个时域符号数量,其他子载波间隔对应的第一阈值(最大时域符号数量)也可根据表2进行确定,这里不再进行赘述。
所述第一阈值的取值根据传输一个TB所使用的子载波间隔和参考子载波间隔确定,所述参考子载波间隔由协议约定或基站配置。第一阈值除了采用上述协议规定的对应关系的方式来确定之外,还可以根据子载波间隔和参考子载波间隔来确定,比如,可以包括:
将传输一个TB所使用的子载波间隔除以所述参考子载波间隔所得的结果,作为所述第一阈值。具体的,第一阈值的取值等于传输一个TB所使用的子载波间隔除以所述参考子载波间隔。例如,参考子载波间隔为15kHz,当使用60kHz子载波间隔传输TB时,该TB最多可占用60/15=4个TTI进行传输。
或者,
将传输一个TB所使用的子载波间隔除以所述参考子载波间隔后,乘以第一参数所得到的结果,作为所述第一阈值。具体的,第一阈值的取值等于传输一个TB所使用的子载波间隔除以所述参考子载波间隔在乘以第一参数。例如,参考子载波间隔为15kHz,当使用60kHz子载波间隔传输TB时,该TB最多可占用(60/15)*14=56个时域符号进行传输。
其中,所述参考子载波间隔可以根据实际情况进行设置,比如前述示例中设置的子载波间隔为15KHz,当然还可以设置为其他数值,只是本实施例中不再进行赘述。
方式二、由终端设备确定第一时域资源长度的方式。如下所述:
根据当前终端设备传输一个TB所采用的子载波间隔确定所述第一时域资源长度。
具体的,可以包括:基于协议预设的第一时域资源长度与当前终端设备传输一个TB所采用的子载波间隔之间的对应关系,确定所述第一时域资源长度。
比如,第一时域资源长度和子载波间隔之间的对应关系,可以为以下表3或表4所示来确定:
| 子载波间隔 | 第一时域资源长度(TTI/slot数量) |
| 15kHZ | 1 |
| 30kHz | 2 |
| 60kHz | 4 |
| 120kHz | 8 |
表3
| 子载波间隔 | 第一时域资源长度(时域符号数量) |
| 15kHZ | 14 |
| 30kHz | 2*14 |
| 60kHz | 4*14 |
| 120kHz | 8*14 |
表4
具体来说,当第一时域资源长度用于表征传输一个TB所能占用的TTI(传输时间间隔)的最大数量或者表征传输一个TB所能占用的时隙slot的最大数量时,可以通过前述表3来确定第一时域资源长度和子载波间隔之间的关系,比如,当子载波间隔为60KHz时,第一时域资源长度可以为4个TTI或者4个时隙,其他的子载波间隔也根据表3来确定,这里不再进行赘述;
当第一时域资源长度用于表征传输一个TB所能占用的时域符号数量时,可以通过前述表2来确定子载波间隔和第一时域资源长度之间的关系,比如,当子载波间隔为120KHz时,对应的第一时域资源长度可以为8*14个时域符号数量,其他子载波间隔对应的第一时域资源长度也可根据表4进行确定,这里不再进行赘述。
所述第一时域资源长度的取值根据传输一个TB所使用的子载波间隔和参考子载波间隔确定,比如,可以包括:
将传输一个TB所使用的子载波间隔除以所述参考子载波间隔所得的结果,作为所述第一时域资源长度。具体的,第一时域资源长度的取值等于传输一个TB所使用的子载波间隔除以所述参考子载波间隔。例如,参考子载波间隔为15kHz,当使用60kHz子载波间隔传输TB时,该TB最多可占用60/15=4个TTI进行传输。
或者,
将传输一个TB所使用的子载波间隔除以所述参考子载波间隔后,乘以第一参数所得到的结果,作为所述第一时域资源长度。具体的,第一时域资源长度的取值等于传输一个TB所使用的子载波间隔除以所述参考子载波间隔在乘以第一参数。例如,参考子载波间隔为15kHz,当使用60kHz子载波间隔传输TB时,该TB最多可占用(60/15)*14=56个时域符号进行传输。
其中,所述参考子载波间隔可以根据实际情况进行设置,比如前述示例中设置的子载波间隔为15KHz,当然还可以设置为其他数值,只是本实施例中不再进行赘述。
前述步骤302中,接收网络侧发来的配置信息,根据所述配置信息确定采用第一物理资源传输目标TB,的具体处理方法参见以下说明:
场景一、
若所述第一时域资源长度为以下之一:传输一个TB所能占用的传输时间间隔TTI的最大数量;传输一个TB所能占用的时隙的最大数量;传输一个TB所能占用的最大时域符号数量。
相应的,所述配置信息用于指示在一个时间单元或TTI或时隙内,传输所述目标TB所使用的时域符号资源。
其中,所述第一物理资源包括至少两个时间单元;所述时间单元为TTI或时隙。
所述根据所述配置信息确定采用第一物理资源传输目标TB可以为:根据配置信息,在所述至少两个时间单元内使用相同的时域符号资源传输所述目标TB。
本场景中,所述终端接收基站发送的配置信息,所述配置信息用于指示目标TB在一个TTI/slot内所使用的时域符号,所述终端在多个TTI/slot内使用相同的时域符号传输所述目标TB,参见图4,在图示出的4个时隙中,均采用时隙中间的时域符号资源作为目标TB占用的时域符号资源;另外,需要指出的是,图中所示的第一物理资源所对应的多个时隙或者多个TTI,为连续的多个时隙或连续的多个TTI。当然,在实际处理中,多个时隙或多个TTI还可以为不连续的多个时隙或TTI。
所述多个TTI/slot的数量等于所述第一时域资源长度;或者,所述多个TTI或多个时隙可以由所述基站指示,且取值不大于所述第一时间资源长度。
场景二、
所述第一时域资源长度为以下之一:传输一个TB所能占用的传输时间间隔TTI的最大数量;传输一个TB所能占用的时隙的最大数量;传输一个TB所能占用的最大时域符号数量。
所述第一物理资源包括至少两个时间单元;所述时间单元为TTI或时隙。
根据所述配置信息,确定在所述至少两个时间单元内使用连续的时域符号资源传输所述目标TB;其中,所述连续的时域符号资源为至少两个时间单元包含的全部时域符号资源中的至少部分时域符号。
其中,配置信息,用于指示传输所述目标TB在所述至少两个时间单元中的第一个时间单元内的时域符号起始位置和在所述至少两个时间单元中的最后一个时间单元内的时域符号的结束位置。
可以理解的是,第一个时间单元内的时域符号起始位置,可以为第一个时间单元内的第一个时域符号,当然还可以为第一个时间单元内的第N个时域符号,N大于1且小于第一时间单元内包含的全部时域符号数量;同样的,最后一个时间单元的时域符号结束位置可以为最后一个时间单元中的最后一个时域符号,还可以为最后一个时间单元中的第M个时域符号,M为大于等于1且小于等于最后一个时间单元所包含的全部时域符号的数量。
具体来说,指示传输所述目标TB在所述至少两个时间单元中的第一个时间单元内的时域符号起始位置和在所述至少两个时间单元中的最后一个时间单元内的时域符号的结束位置的方式,可以为:
第一种、配置信息指示起始符号位置(相对于一个slot内)和结束符号位置(相对与一个slot内),所述起始符号和结束符号分别位于第一个slot和最后一个slot。如,起始符号为符号2,结束符号为符号10,则表示在第一slot内符号2开始,在最后一个slot内符号10结束。
第二种、配置信息指示起始符号位置(相对于一个slot内)和持续时间(相对于一个slot内),根据持续时间得到结束符号位置(相对于一个slot内);其中,所述起始符号和结束符号分别位于第一个slot或最后一个slot。如,起始符号为符号2,持续时间为8,则确定结束符号为符号10,则表示在第一slot内符号2开始,在最后一个slot内符号10结束。这种方式,能够重用现有的DCI指示方法,也就是只支持一个slot内调度的方法,从而实现多个slot的调度。
第三种、指示传输目标TB的符号起始位置,或者,指示传输目标TB的符号起始位置以及符号结束位置(相对于多个slot),或者,指示传输目标TB的符号起始位置以及持续长度(包括多个slot)。
这种方式中,可以通过配置信息指示多个信息之一,比如,第一个时间单元中的起始符号为3,那么可以理解为以该起始符号开始进行TB传输,直至TB完成传输;或者,配置信息中设置起始符号为符号2,持续长度为28个符号(一个slot包括14的符号),从起始符号2开始传输TB,直至第三个时间单元中的第2个时间符号终止传输;或者,配置信息中指示起始符号为符号2,结束符号为自开始slot之后的第2个slot内的符号10。
以上示例,可以参见图5,配置信息用于指示目标TB在多个TTI/slot中的第一TTI/slot内的符号起始位置和最后一个TTI/slot内的符号结束位置,中间TTI/slot的所有(可用)符号都用于传输所述目标TB,其中可用符号表示未被其他高优先信道/信号占用的时域符号。其中,所述多个TTI/slot的数量等于所述第一时域资源长度;或者由所述基站指示,且取值不大于所述第一时间资源长度。如图中所示,第一时间资源长度占用了连续的多个时隙(或者TTI)中的连续的时域符号资源。
再进一步地,本场景中第一物理资源可以为:符号起始位置以及符号结束位置内所包含的全部时域符号;
或者,
符号起始位置以及符号结束位置内所包含的全部可用时域符号;其中,所述可用时域符号为高优先级的信号或信道未占用的时域符号。
也就是说,第一物理资源可以为前面确定的全部时域符号,当然还可以为部分时域符号;当第一物理资源包含前述确定的全部时域符号中的部分时域符号时,需要将已经被其他高优先级的信号或信道占用的时域符号去掉,将剩余符号用于传输目标TB。
所述方法还包括:根据所述第一物理资源中时域符号的总数,确定所述目标TB对应的传输块大小TBS。也就是说,根据时域符号的总数来确定一次传输目标TB所对应的传输块大小。比如,当前时域符号可以包含30个时域符号,那么对应的传输块大小TBS则为对应30个时域符号的大小。
可见,通过采用上述方案,就能够根据一个TB采用的子载波间隔相关的第一时域资源长度,来确定传输目标TB采用的第一物理资源并传输目标TB;如此,就能够根据子载波间隔灵活的调整TB传输对应的物理资源,从而保证了系统的传输效率。
实施例二、
本发明实施例提供了一种数据传输方法,应用于网络设备,如图6所示,包括:
步骤601:向终端设备发送第一信息,所述第一信息用于指示第一时域资源长度;其中,所述第一时域资源长度与当前终端设备传输一个TB所采用的子载波间隔相关、且所述第一时域资源长度用于确定所述终端设备传输一个传输块TB所能使用的时域资源的最大值;
步骤602:向终端设备发送配置信息,接收终端设备在第一物理资源上传输的目标TB;其中,所述第一物理资源的时间长度不大于所述第一时域资源长度。
本发明实施例中,所述第一时域资源长度可以理解为用于确定所述终端设备传输一个传输块TB所能使用的时域资源的最大值。
其中,所述第一时域资源长度可以包括以下几种表示方式:
传输一个TB所能占用的TTI(传输时间间隔)的最大数量;
传输一个TB所能占用的时隙slot的最大数量。
传输一个TB所能占用的时域符号的最大数量。
具体地,可以通过RRC信令预配置时域资源列表实现,即列表中包含的最大时域符号数量。
基于前述方案下面针对如何获取第一时域资源长度进行说明:
本申请可以提供两种方式一种为通过网络侧发送的信息确定第一时域资源长度;另一种为由终端设备自身处理来确定第一时域资源长度。
本实施例主要针对网络侧向终端发送第一信息以确定第一时域资源长度的方式来进行说明:
所述第一时域资源长度不大于第一阈值;其中,所述第一阈值的取值与当前终端设备传输一个TB所采用的子载波间隔相关。也就是说,第一时域资源长度与第一阈值相关,并且第一阈值与传输TB的子载波间隔相关。
其中,所述第一阈值的取值与子载波间隔之间的对应关系由协议确定,或者,所述第一阈值的取值根据传输一个TB所使用的子载波间隔以及参考子载波间隔确定。
关于第一阈值的取值和子载波间隔之间的对应关系,可以根据预设的表格来确定,比如,如下表1或表2所示:
| 子载波间隔 | 第一阈值(TTI/slot数量) |
| 15kHZ | 1 |
| 30kHz | 2 |
| 60kHz | 4 |
| 120kHz | 8 |
表1
| 子载波间隔 | 第一阈值(时域符号数量) |
| 15kHZ | 14 |
| 30kHz | 2*14 |
| 60kHz | 4*14 |
| 120kHz | 8*14 |
表2
具体来说,当第一时域资源长度用于表征传输一个TB所能占用的TTI(传输时间间隔)的最大数量或者表征传输一个TB所能占用的时隙slot的最大数量时,可以通过前述表1来确定第一阈值和子载波间隔之间的关系,比如,当子载波间隔为30KHz时,第一阈值可以为2个TTI或者2个时隙,其他的子载波间隔也根据表1来确定,这里不再进行赘述;
当第一时域资源长度用于表征传输一个TB所能占用的时域符号数量时,可以通过前述表2来确定子载波间隔和第一阈值之间的关系,比如,当子载波间隔为60KHz时,对应的第一阈值可以为4*14个时域符号数量,其他子载波间隔对应的第一阈值(最大时域符号数量)也可根据表2进行确定,这里不再进行赘述。
所述第一阈值的取值根据传输一个TB所使用的子载波间隔和参考子载波间隔确定,所述参考子载波间隔由协议约定或基站配置。第一阈值除了采用上述协议规定的对应关系的方式来确定之外,还可以根据子载波间隔和参考子载波间隔来确定,比如,可以包括:
将传输一个TB所使用的子载波间隔除以所述参考子载波间隔所得的结果,作为所述第一阈值。 具体的,第一阈值的取值等于传输一个TB所使用的子载波间隔除以所述参考子载波间隔。例如,参考子载波间隔为15kHz,当使用60kHz子载波间隔传输TB时,该TB最多可占用60/15=4个TTI进行传输。
或者,
将传输一个TB所使用的子载波间隔除以所述参考子载波间隔后,乘以第一参数所得到的结果,作为所述第一阈值。具体的,第一阈值的取值等于传输一个TB所使用的子载波间隔除以所述参考子载波间隔在乘以第一参数。例如,参考子载波间隔为15kHz,当使用60kHz子载波间隔传输TB时,该TB最多可占用(60/15)*14=56个时域符号进行传输。
其中,所述参考子载波间隔可以根据实际情况进行设置,比如前述示例中设置的子载波间隔为15KHz,当然还可以设置为其他数值,只是本实施例中不再进行赘述。
确定配置信息,进而基于配置信息指示终端设备采用第一物理资源传输目标TB,的具体处理方法参见以下说明:
场景一、
所述配置信息用于指示在一个时间单元或TTI或时隙内,传输所述目标TB所使用的时域符号资源。
其中,所述第一物理资源包括至少两个时间单元;所述时间单元为TTI或时隙。
所述根据所述配置信息确定采用第一物理资源传输目标TB可以为:根据配置信息,在所述至少两个时间单元内使用相同的时域符号资源传输所述目标TB。
本场景中,所述终端接收基站发送的配置信息,所述配置信息用于指示目标TB在一个TTI/slot内所使用的时域符号,所述终端在多个TTI/slot内使用相同的时域符号传输所述目标TB,参见图4,在图示出的4个时隙中,均采用时隙中间的时域符号资源作为目标TB占用的时域符号资源;另外,需要指出的是,图中所示的第一物理资源所对应的多个时隙或者多个TTI,为连续的多个时隙或连续的多个TTI。当然,在实际处理中,多个时隙或多个TTI还可以为不连续的多个时隙或TTI。
所述多个TTI/slot的数量等于所述第一时域资源长度;或者,所述多个TTI或多个时隙可以由所述基站指示,且取值不大于所述第一时间资源长度。
场景二、
所述第一时域资源长度为以下之一:传输一个TB所能占用的传输时间间隔TTI的最大数量;传输一个TB所能占用的时隙的最大数量;传输一个TB所能占用的最大时域符号数量。
所述第一物理资源包括至少两个时间单元;所述时间单元为TTI或时隙。
所述配置信息用于指示传输所述目标TB在所述至少两个时间单元中的第一个时间单元内的时域符号起始位置和在所述至少两个时间单元中的最后一个时间单元内的时域符号的结束位置。
可以理解的是,第一个时间单元内的时域符号起始位置,可以为第一个时间单元内的第一个时域符号,当然还可以为第一个时间单元内的第N个时域符号,N大于1且小于第一时间单元内包含的全部时域符号数量;同样的,最后一个时间单元的时域符号结束位置可以为最后一个时间单元中的最后一个时域符号,还可以为最后一个时间单元中的第M个时域符号,M为大于等于1且小于等于最后一个时间单元所包含的全部时域符号的数量。
具体来说,指示传输所述目标TB在所述至少两个时间单元中的第一个时间单元内的时域符号起始位置和在所述至少两个时间单元中的最后一个时间单元内的时域符号的结束位置的方式,可以为:
第一种、配置信息指示起始符号位置(相对于一个slot内)和结束符号位置(相对与一个slot内),所述起始符号和结束符号分别位于第一个slot和最后一个slot。如,起始符号为符号2,结束符号为符号10,则表示在第一slot内符号2开始,在最后一个slot内符号10结束。
第二种、配置信息指示起始符号位置(相对于一个slot内)和持续时间(相对于一个slot内),根据持续时间得到结束符号位置(相对于一个slot内);其中,所述起始符号和结束符号分别位于第一个slot或最后一个slot。如,起始符号为符号2,持续时间为8,则确定结束符号为符号10,则表示在第一slot内符号2开始,在最后一个slot内符号10结束。这种方式,能够重用现有的DCI指示方法,也就是只支持一个slot内调度的方法,从而实现多个slot的调度。
第三种、指示传输目标TB的符号起始位置,或者,指示传输目标TB的符号起始位置以及符号结束位置(相对于多个slot),或者,指示传输目标TB的符号起始位置以及持续长度(包括多个slot)。
这种方式中,可以通过配置信息指示多个信息之一,比如,第一个时间单元中的起始符号为3, 那么可以理解为以该起始符号开始进行TB传输,直至TB完成传输;或者,配置信息中设置起始符号为符号2,持续长度为28个符号(一个slot包括14的符号),从起始符号2开始传输TB,直至第三个时间单元中的第2个时间符号终止传输;或者,配置信息中指示起始符号为符号2,结束符号为自开始slot之后的第2个slot内的符号10。
以上示例,可以参见图5,配置信息用于指示目标TB在多个TTI/slot中的第一TTI/slot内的符号起始位置和最后一个TTI/slot内的符号结束位置,中间TTI/slot的所有(可用)符号都用于传输所述目标TB,其中可用符号表示未被其他高优先信道/信号占用的时域符号。其中,所述多个TTI/slot的数量等于所述第一时域资源长度;或者由所述基站指示,且取值不大于所述第一时间资源长度。如图中所示,第一时间资源长度占用了连续的多个时隙(或者TTI)中的连续的时域符号资源。
再进一步地,本场景中第一物理资源可以为:符号起始位置以及符号结束位置内所包含的全部时域符号;
或者,
符号起始位置以及符号结束位置内所包含的全部可用时域符号;其中,所述可用时域符号为高优先级的信号或信道未占用的时域符号。
也就是说,第一物理资源可以为前面确定的全部时域符号,当然还可以为部分时域符号;当第一物理资源包含前述确定的全部时域符号中的部分时域符号时,需要将已经被其他高优先级的信号或信道占用的时域符号去掉,将剩余符号用于传输目标TB。
所述方法还包括:根据所述第一物理资源中时域符号的总数,确定所述目标TB对应的传输块大小TBS。也就是说,根据时域符号的总数来确定一次传输目标TB所对应的传输块大小。比如,当前时域符号可以包含30个时域符号,那么对应的传输块大小TBS则为对应30个时域符号的大小。
可见,通过采用上述方案,就能够根据一个TB采用的子载波间隔相关的第一时域资源长度,来确定传输目标TB采用的第一物理资源并传输目标TB;如此,就能够根据子载波间隔灵活的调整TB传输对应的物理资源,从而保证了系统的传输效率。

其中,所述第一时域资源长度可以包括以下几种表示方式:
传输一个TB所能占用的TTI(传输时间间隔)的最大数量;
传输一个TB所能占用的时隙slot的最大数量。
传输一个TB所能占用的时域符号的最大数量。
具体地,可以通过RRC信令预配置时域资源列表实现,即列表中包含的最大时域符号数量。
基于前述方案下面针对如何获取第一时域资源长度进行说明:
本申请可以提供两种方式一种为通过网络侧发送的信息确定第一时域资源长度;另一种为由终端设备自身处理来确定第一时域资源长度。
具体的,
方式一、第一处理单元71,通过第一通信单元72接收网络侧发送的第一信息;其中,所述第一信息用于指示第一时域资源长度。
相应的,可以根据第一信息中指示的内容直接确定第一时域资源长度。
进一步地,所述第一时域资源长度不大于第一阈值;其中,所述第一阈值的取值与当前终端设备传输一个TB所采用的子载波间隔相关。也就是说,第一时域资源长度与第一阈值相关,并且第一阈值与传输TB的子载波间隔相关。
其中,所述第一阈值的取值与子载波间隔之间的对应关系由协议确定,或者,所述第一阈值的取值根据传输一个TB所使用的子载波间隔以及参考子载波间隔确定。
关于第一阈值的取值和子载波间隔之间的对应关系,可以根据预设的表格来确定,比如,如下表1或表2所示:
| 子载波间隔 | 第一阈值(TTI/slot数量) |
| 15kHZ | 1 |
| 30kHz | 2 |
| 60kHz | 4 |
| 120kHz | 8 |

表2
具体来说,当第一时域资源长度用于表征传输一个TB所能占用的TTI(传输时间间隔)的最大数量或者表征传输一个TB所能占用的时隙slot的最大数量时,可以通过前述表1来确定第一阈值和子载波间隔之间的关系,比如,当子载波间隔为30KHz时,第一阈值可以为2个TTI或者2个时隙,其他的子载波间隔也根据表1来确定,这里不再进行赘述;

所述第一阈值的取值根据传输一个TB所使用的子载波间隔和参考子载波间隔确定,所述参考子载波间隔由协议约定或基站配置。第一阈值除了采用上述协议规定的对应关系的方式来确定之外,还可以根据子载波间隔和参考子载波间隔来确定,比如,可以包括:
第一处理单元71,将传输一个TB所使用的子载波间隔除以所述参考子载波间隔所得的结果,作为所述第一阈值。具体的,第一阈值的取值等于传输一个TB所使用的子载波间隔除以所述参考子载波间隔。例如,参考子载波间隔为15kHz,当使用60kHz子载波间隔传输TB时,该TB最多可占用60/15=4个TTI进行传输。
或者,
第一处理单元71,将传输一个TB所使用的子载波间隔除以所述参考子载波间隔后,乘以第一参数所得到的结果,作为所述第一阈值。具体的,第一阈值的取值等于传输一个TB所使用的子载波间隔除以所述参考子载波间隔在乘以第一参数。例如,参考子载波间隔为15kHz,当使用60kHz子载波间隔传输TB时,该TB最多可占用(60/15)*14=56个时域符号进行传输。
其中,所述参考子载波间隔可以根据实际情况进行设置,比如前述示例中设置的子载波间隔为15KHz,当然还可以设置为其他数值,只是本实施例中不再进行赘述。
方式二、由终端设备确定第一时域资源长度的方式。如下所述:

具体的,基于协议预设的第一时域资源长度与当前终端设备传输一个TB所采用的子载波间隔之间的对应关系,确定所述第一时域资源长度。
比如,第一时域资源长度和子载波间隔之间的对应关系,可以为以下表3或表4所示来确定:
| 子载波间隔 | 第一时域资源长度(TTI/slot数量) |
| 15kHZ | 1 |
| 30kHz | 2 |
| 60kHz | 4 |
| 120kHz | 8 |

| 15kHZ | 14 |
| 30kHz | 2*14 |
| 60kHz | 4*14 |
| 120kHz | 8*14 |
表4
具体来说,当第一时域资源长度用于表征传输一个TB所能占用的TTI(传输时间间隔)的最大数量或者表征传输一个TB所能占用的时隙slot的最大数量时,可以通过前述表3来确定第一时域资源长度和子载波间隔之间的关系,比如,当子载波间隔为60KHz时,第一时域资源长度可以为4个TTI或者4个时隙,其他的子载波间隔也根据表3来确定,这里不再进行赘述;
当第一时域资源长度用于表征传输一个TB所能占用的时域符号数量时,可以通过前述表2来确定子载波间隔和第一时域资源长度之间的关系,比如,当子载波间隔为120KHz时,对应的第一时域资源长度可以为8*14个时域符号数量,其他子载波间隔对应的第一时域资源长度(最大时域符号数量)也可根据表4进行确定,这里不再进行赘述。
所述第一时域资源长度的取值根据传输一个TB所使用的子载波间隔和参考子载波间隔确定,比如,可以包括:
第一处理单元71,将传输一个TB所使用的子载波间隔除以所述参考子载波间隔所得的结果,作为所述第一时域资源长度。具体的,第一时域资源长度的取值等于传输一个TB所使用的子载波间隔除以所述参考子载波间隔。例如,参考子载波间隔为15kHz,当使用60kHz子载波间隔传输TB时,该TB最多可占用60/15=4个TTI进行传输。
或者,
第一处理单元71,将传输一个TB所使用的子载波间隔除以所述参考子载波间隔后,乘以第一参数所得到的结果,作为所述第一时域资源长度。具体的,第一时域资源长度的取值等于传输一个TB所使用的子载波间隔除以所述参考子载波间隔在乘以第一参数。例如,参考子载波间隔为15kHz,当使用60kHz子载波间隔传输TB时,该TB最多可占用(60/15)*14=56个时域符号进行传输。
其中,所述参考子载波间隔可以根据实际情况进行设置,比如前述示例中设置的子载波间隔为15KHz,当然还可以设置为其他数值,只是本实施例中不再进行赘述。
接收网络侧发来的配置信息,根据所述配置信息确定采用第一物理资源传输目标TB,的具体处理方法参见以下说明:
场景一、
若所述第一时域资源长度为以下之一:传输一个TB所能占用的传输时间间隔TTI的最大数量;传输一个TB所能占用的时隙的最大数量;传输一个TB所能占用的最大时域符号数量。
相应的,所述配置信息用于指示在一个时间单元或TTI或时隙内,传输所述目标TB所使用的时域符号资源。
其中,所述第一物理资源包括至少两个时间单元;所述时间单元为TTI或时隙。
所述第一处理单元71,根据配置信息,在所述至少两个时间单元内使用相同的时域符号资源传输所述目标TB。
本场景中,所述终端接收基站发送的配置信息,所述配置信息用于指示目标TB在一个TTI/slot内所使用的时域符号,所述终端在多个TTI/slot内使用相同的时域符号传输所述目标TB,参见图4,在图示出的4个时隙中,均采用时隙中间的时域符号资源作为目标TB占用的时域符号资源;另外,需要指出的是,图中所示的第一物理资源所对应的多个时隙或者多个TTI,为连续的多个时隙或连续的多个TTI。当然,在实际处理中,多个时隙或多个TTI还可以为不连续的多个时隙或TTI。
所述多个TTI/slot的数量等于所述第一时域资源长度;或者,所述多个TTI或多个时隙可以由所述基站指示,且取值不大于所述第一时间资源长度。
场景二、
所述第一时域资源长度为以下之一:传输一个TB所能占用的传输时间间隔TTI的最大数量;传输一个TB所能占用的时隙的最大数量;传输一个TB所能占用的最大时域符号数量。
所述第一物理资源包括至少两个时间单元;所述时间单元为TTI或时隙。
第一处理单元71,根据所述配置信息,确定在所述至少两个时间单元内使用连续的时域符号资源传输所述目标TB;其中,所述连续的时域符号资源为至少两个时间单元包含的全部时域符号资源中的至少部分时域符号。
其中,配置信息,用于指示传输所述目标TB在所述至少两个时间单元中的第一个时间单元内的时域符号起始位置和在所述至少两个时间单元中的最后一个时间单元内的时域符号的结束位置。
可以理解的是,第一个时间单元内的时域符号起始位置,可以为第一个时间单元内的第一个时域符号,当然还可以为第一个时间单元内的第N个时域符号,N大于1且小于第一时间单元内包含的全部时域符号数量;同样的,最后一个时间单元的时域符号结束位置可以为最后一个时间单元中的最后一个时域符号,还可以为最后一个时间单元中的第M个时域符号,M为大于等于1且小于等于最后一个时间单元所包含的全部时域符号的数量。
具体来说,指示传输所述目标TB在所述至少两个时间单元中的第一个时间单元内的时域符号起始位置和在所述至少两个时间单元中的最后一个时间单元内的时域符号的结束位置的方式,可以为:
第一种、配置信息指示起始符号位置(相对于一个slot内)和结束符号位置(相对与一个slot内),所述起始符号和结束符号分别位于第一个slot和最后一个slot。如,起始符号为符号2,结束符号为符号10,则表示在第一slot内符号2开始,在最后一个slot内符号10结束。
第二种、配置信息指示起始符号位置(相对于一个slot内)和持续时间(相对于一个slot内),根据持续时间得到结束符号位置(相对于一个slot内);其中,所述起始符号和结束符号分别位于第一个slot或最后一个slot。如,起始符号为符号2,持续时间为8,则确定结束符号为符号10,则表示在第一slot内符号2开始,在最后一个slot内符号10结束。这种方式,能够重用现有的DCI指示方法,也就是只支持一个slot内调度的方法,从而实现多个slot的调度。
第三种、指示传输目标TB的符号起始位置,或者,指示传输目标TB的符号起始位置以及符号结束位置(相对于多个slot),或者,指示传输目标TB的符号起始位置以及持续长度(包括多个slot)。
这种方式中,可以通过配置信息指示多个信息之一,比如,第一个时间单元中的起始符号为3,那么可以理解为以该起始符号开始进行TB传输,直至TB完成传输;或者,配置信息中设置起始符号为符号2,持续长度为28个符号(一个slot包括14的符号),从起始符号2开始传输TB,直至第三个时间单元中的第2个时间符号终止传输;或者,配置信息中指示起始符号为符号2,结束符号为自开始slot之后的第2个slot内的符号10。
以上示例,可以参见图5,配置信息用于指示目标TB在多个TTI/slot中的第一TTI/slot内的符号起始位置和最后一个TTI/slot内的符号结束位置,中间TTI/slot的所有(可用)符号都用于传输所述目标TB,其中可用符号表示未被其他高优先信道/信号占用的时域符号。其中,所述多个TTI/slot的数量等于所述第一时域资源长度;或者由所述基站指示,且取值不大于所述第一时间资源长度。如图中所示,第一时间资源长度占用了连续的多个时隙(或者TTI)中的连续的时域符号资源。
再进一步地,本场景中第一物理资源可以为:符号起始位置以及符号结束位置内所包含的全部时域符号;
或者,
符号起始位置以及符号结束位置内所包含的全部可用时域符号;其中,所述可用时域符号为高优先级的信号或信道未占用的时域符号。
也就是说,第一物理资源可以为前面确定的全部时域符号,当然还可以为部分时域符号;当第一物理资源包含前述确定的全部时域符号中的部分时域符号时,需要将已经被其他高优先级的信号或信道占用的时域符号去掉,将剩余符号用于传输目标TB。
所述第一处理单元71,根据所述第一物理资源中时域符号的总数,确定所述目标TB对应的传输块大小TBS。也就是说,根据时域符号的总数来确定一次传输目标TB所对应的传输块大小。比如,当前时域符号可以包含30个时域符号,那么对应的传输块大小TBS则为对应30个时域符号的大小。
可见,通过采用上述方案,就能够根据一个TB采用的子载波间隔相关的第一时域资源长度,来确定传输目标TB采用的第一物理资源并传输目标TB;如此,就能够根据子载波间隔灵活的调整TB传输对应的物理资源,从而保证了系统的传输效率。

所述第一阈值的取值根据传输一个TB所使用的子载波间隔和参考子载波间隔确定,所述参考子载波间隔由协议约定或基站配置。第一阈值除了采用上述协议规定的对应关系的方式来确定之外,还可以根据子载波间隔和参考子载波间隔来确定,比如,所述网络设备还包括:
第二处理单元82,将传输一个TB所使用的子载波间隔除以所述参考子载波间隔所得的结果,作为所述第一阈值。具体的,第一阈值的取值等于传输一个TB所使用的子载波间隔除以所述参考子载波间隔。例如,参考子载波间隔为15kHz,当使用60kHz子载波间隔传输TB时,该TB最多可占用60/15=4个TTI进行传输。
或者,
