Abstract
本申请实施例提供了一种无线通信方法、终端设备以及网络设备,所述方法包括:在所述终端设备发生天线转换的时间单元内或在连续的多个时间单元中的每一个时间单元内,向网络设备发送探测参考信号SRS。本申请提供的方案避免了为终端设备的天线转换过程和SRS分别配置各自的时间单元,能够提升资源利用率以及提升数据吞吐量。
Description
本申请实施例涉及通信领域,并且更具体地,涉及无线通信方法、终端设备以及网络设备。
在新空口(New Radio,NR)中,探测参考信号(Sounding Reference Signal,SRS)信号用于信道探测。网络设备为了获取上行信道的无线传播特性,会配置终端设备在一定的时频资源发射SRS,网络设备通过解调接收到的SRS可以知道当前信道的情况。当终端设备具有多个发射天线或接收天线的时候,网络设备将配置终端设备在多个天线端口上依次发射SRS。网络设备接收到多个端口的SRS后,可以得到完整的多输入多输出(Multiple Input Multiple Output,MIMO)信道空间传输特性,从而可以更好的进行码本选择等操作。
考虑到终端设备切换天线时需要的转换时间(Transient period,TP),通信标准引入了保护时间(Guard Period,GP),终端设备在GP内不做任何发射。
但是,由于GP的长度为对应到不同的子载波间隔(subcarrier spacing,SCS)的1个符号或两个符号,因此,GP在网络设备的调度上带来的影响则是留出了一个符号或两个符号的GP,进而降低了终端设备的数据吞吐量。
此外,相关技术只考虑了两个探测参考信号(Sounding Reference Signal,SRS)的资源或资源集之间的时间间隔的要求,即需要保证两个SRS的资源或资源集之间的时间间隔大于或等于GP,且当两个SRS的资源或资源集之间的时间间隔大于GP时,也不能在两个SRS的资源或资源集之间的时间间隔内进行数据传输。然而,当两个SRS的资源或资源集之间的时间间隔过大时,如果不允许终端设备进行其它信号的发射必然会造成资源浪费并降低了数据吞吐量。

在新空口(New Radio,NR)中,探测参考信号(Sounding Reference Signal,SRS)信号用于信道探测。网络设备为了获取上行信道的无线传播特性,会配置终端设备在一定的时频资源发射SRS,网络设备通过解调接收到的SRS号可以知道当前信道的情况。当终端设备具有多个发射天线或接收天线的时候,网络设备将配置终端设备在多个天线端口上依次发射SRS。网络设备接收到多个端口的SRS后,可以得到完整的多输入多输出(Multiple Input Multiple Output,MIMO)信道空间传输特性,从而可以更好的进行码本选择等操作。
对于时分双工(Time Division Duplexing,TDD)频段来说,上行信道和下行信道具有互异性,且终端设备通常具有的下行天线数量多余上行天线数量,因此终端设备也将在纯下行天线进行SRS信号的发射,用于网络设备对下行信道的估计。
图2是本申请实施例提供的SRS轮发的示意图。
如图2所示,终端设备具有四个接收天线(即天线Ant0~天线Ant3),其中天线Ant0同时作为发射天线。网络设备为了获取四个接收天线对应的信道特性,将为终端设备配置四个SRS时频资源(即SRS资源0~SRS资源3),终端设备依次利用这四个接收天线在其对应的SRS资源上发射SRS信号。例如终端设备可以利用天线Ant0在SRS资源0上发送SRS,利用天线Ant1在SRS资源1上发送SRS,利用天线Ant2在SRS资源2上发送SRS,以及利用天线Ant3在SRS资源3上发送SRS。
终端设备切换天线需要一定的时间,因此,当终端设备从一个天线切换到另外一个天线发射SRS信号时将需要一定的转换时间(Transient period,TP),TP的长度因终端设备而异,例如FR1下的TP最长不超过15us。考虑到TP,通信标准引入了一个保护时间(Guard Period,GP),终端设备在GP内不做任何发射。
图3是本申请实施例提供的SRS轮发和GP之间的位置关系的示意图。
如图3所示,终端设备需要向网络设备轮发SRS0~SRS3时,在发送SRS0之后需要间隔一个GP才能发送SRS1,在发送SRS1之后需要间隔一个GP才能发送SRS2,在发送SRS2之后需要间隔一个GP才能发送SRS3。
但是,由于GP的长度为对应到不同的子载波间隔(subcarrier spacing,SCS)的1个符号或两个符号,因此,GP在网络设备的调度上带来的影响则是留出了一个符号或两个符号的GP,进而降低了终端设备的数据吞吐量。
此外,相关技术只考虑了两个探测参考信号(Sounding Reference Signal,SRS)的资源或资源集之间的时间间隔的要求,即需要保证两个SRS的资源或资源集之间的时间间隔大于或等于GP,且当两个SRS的资源或资源集之间的时间间隔大于GP时,也不能在两个SRS的资源或资源集之间的时间间隔内进行数据传输。然而,当两个SRS的资源或资源集之间的时间间隔过大时,如果不允许终端设备进行其它信号的发射必然会造成资源浪费并降低了数据吞吐量。
有鉴于此,本申请实施例提供了一种无线通信方法、终端设备以及网络设备,能够提升资源利用率以及提升数据吞吐量。
图4是本申请实施例提供的无线通信方法200的示意性流程图,所述无线通信方法200可以由终端设备和网络设备交互执行。图4中所示的终端设备可以是如图1所示的终端设备,图4中所示的网络设备可以是如图1所示的接入网设备。
如图4所示,所述方法200可包括以下部分或全部内容:
S210,终端设备在所述终端设备发生天线转换的时间单元内或在连续的多个时间单元中的每一个时间单元内,向网络设备发送SRS。
换言之,网络设备在所述终端设备发生天线转换的时间单元内或在连续的多个时间单元中的每一个时间单元内,接收所述终端设备发送的SRS。进一步的,网络设备收到所述终端设备发送的SRS后,可基于收到的SRS后,可以得到完整的MIMO信道空间传输特性,从而可以更好的进行码本选择等操作。
本实施例中,在终端设备发生天线转换的时间单元内或在连续的多个时间单元中的每一个时间单元内,向网络设备发送SRS;能够在不引入GP的基础上,考虑到终端设备切换天线需要的时间,相应的,不仅避免了GP在网络设备的调度上带来的影响,还能够提升终端设备的上行传输性能,例如能够提升资源利用率以及数据吞吐量。
示例性地,在所述终端设备的TP小于GP的情况下,终端设备在所述终端设备发生天线转换的时间单元内或在连续的多个时间单元中的每一个时间单元内,向网络设备发送SRS,以充分利用所述终端设备发生天线转换的时间单元的资源,进而提升数据吞吐量。
值得注意的是,本申请将天线转换需要的时间(即TP)和终端设备发射SRS需要的时间设计在同一个时间单元内,即网络设备可以通过在单个时间单元内除TP之外的剩余时间上接收到的稳定信号完成SRS的解调。
示例性地,GP的长度为对应到不同的NR子载波间隔(subcarrier spacing,SCS)的1个符号或两个符号。下面结合表1对GP的长度和SCS之间的对应关系进行示例性说明。
表1
SCS | GP的长度(符号) | GP的长度(us) |
15khz | 1 | 71.43 |
30khz | 1 | 35.71 |
60khz | 1 | 17.86 |
120khz | 2 | 17.86 |
如表1所示,不同SCS对应的用于进行天线切换的GP的长度不同,且GP的长度为一个符号或2个符号。
然而,终端设备在不同天线上发射SRS时,对于FR1(7.125GHz以下频段)而言,其需要的TP在硬件上不超过15us。下面结合表2对TP和GP进行比较。
表2
SCS | GP的长度(us) | TP的长度(us) | TP占GP长度的比例 |
15khz | 71.43 | 15 | 21% |
30khz | 35.71 | 15 | 42% |
60khz | 17.86 | 15 | 84% |
如表2所示,若TP的长度为15us,则终端设备的TP在15khz SCS下最多占21%,在30khz SCS下最多占42%。
考虑到TP的引入的初衷是因为终端设备需要一定的时间去完成从一个发射天线切换到另外一个发射天线,以及进行硬件发射通路的调整(比如发射功率的调整)。在这个时间段内终端设备的发射信号将处于不稳定的状态,信号质量可能无法保证,因此,终端设备不能在这段时间内向网络设备发送任何上行信息。但是,对于15khz SCS和30khz SCS来说,TP在整个GP里面所占的比例并不高,网络设备是具有通过GP内剩余的稳定信号完成解调的潜在有能力的,尤其是终端设备的TP比15us要低的时候。有鉴于此,本申请将终端设备发生天线转换的时间单元设计为用于向网络设备发送SRS的时间单元;能够在不引入GP的基础上,考虑到终端设备切换天线需要的时间,相应的,不仅避免了GP在网络设备的调度上带来的影响,还能够提升终端设备的上行传输性能,例如能够提升资源利用率以及数据吞吐量。
图5是本申请实施例提供的网络设备通过GP内剩余的稳定信号完成解调的示意图。
如图5所述,网络设备在一个GP内除TP之外的时间内,实际上是有能力通过GP内剩余的稳定信号完成解调的;换言之,终端设备可以在一个GP内除TP之外的时间内,向网络设备发送上行信息或信号的。
图6是本申请实施例提供的有GP的情况下的SRS轮发和无GP的情况下的SRS轮发的示意图。
如图6所示,假设一个GP为一个符号且用于传输SRS的时间单元为一个符号,在有GP的情况下,每两个用于传输SRS的符号之间需要间隔一个GP,然而,在无GP的情况下,可以在连续的符号上向网络设备发送SRS,终端设备只需要4个符号就可以完成SRS在四个天线端口上的轮流发射,与有GP的情况相比,可以节省3个GP,即能够提升资源利用率以及数据吞吐量。
应当理解,本申请对涉及的时间单元不作具体限定。示例性地,所述时间单元包括但不限于:符号、时隙、子帧、半帧或无线帧等。
在一些实施例中,所述方法200还可包括:

示例性地,由于终端设备的天线转换所需的时间通常会低于某一阈值,因此,所述多个候选TP中的每一个候选TP可以小于或等于预设TP。例如,所述预设TP可以是15us或其他数值。即所述多个候选TP可以是小于或等于15us的多个TP,如3us、6us、9us、12us等。终端设备根据实际情况上报支持的TP给网络设备。网络设备收到终端设备上报的TP后可以决定是否给终端设备配置在所述终端设备发生天线转换的时间单元内或在连续的多个时间单元中的每一个时间单元内用于发送SRS的资源或 资源集,即不采用GP的方式接收SRS。
示例性地,所述第一信息可通过至少一个比特位的取值在多个候选TP中指示所述终端设备的TP。
举例来说,假设所述多个候选TP为3us、6us、9us、12us,此时,所述终端设备可以通过2bit来完成在多个候选TP中指示所述终端设备的TP。例如,所述第一信息为00时指示所述终端设备的TP为3us,所述第一信息为01时指示所述终端设备的TP为6us,所述第一信息为10时指示所述终端设备的TP为9us,所述第一信息为11时指示所述终端设备的TP为12us。当然,在其他可替代实施例中,所述至少一个比特为也可是其他数量个比特位,以及所述至少一个比特位的取值和候选TP之间也可以是其他对应关系,本申请对此不作具体限定。
在一些实施例中,所述第一信息用于指示所述终端设备的TP是否小于或等于第一阈值,和/或,所述第一信息用于指示所述终端设备的TP是否大于或等于所述第一阈值。
在一些实施例中,所述第一阈值为预定义的,或所述第一阈值通过所述终端设备进行上报,或所述第一阈值由所述网络设备配置或指示。
示例性地,所述网络设备接收到所述第一信息后,基于所述终端设备的TP是否小于或等于第一阈值,确定是否调度终端设备在所述终端设备发生天线转换的时间单元内或在连续的多个时间单元中的每一个时间单元内发送SRS;或者说,所述网络设备可基于所述终端设备的TP是否小于或等于第一阈值,确定是否为所述终端设备预留用于所述终端设备进行天线转换的GP。例如,所述终端设备的TP小于或等于第一阈值时,说明所述网络设备可以承受所述终端设备的TP,此时,所述网络设备可以调度终端设备在所述终端设备发生天线转换的时间单元内或在连续的多个时间单元中的每一个时间单元内发送SRS,即可以不为所述终端设备预留用于所述终端设备进行天线转换的GP;否则,所述网络设备不调度终端设备在所述终端设备发生天线转换的时间单元内或在连续的多个时间单元中的每一个时间单元内发送SRS,即需要为所述终端设备预留用于所述终端设备进行天线转换的GP。
示例性地,所述第一信息可通过1个比特位指示所述终端设备的TP是否小于或等于第一阈值,和/或,所述第一信息可通过所述1个比特位指示所述终端设备的TP是否大于或等于所述第一阈值。
举例来说,假设所述第一阈值为7us,此时,所述终端设备可以通过1bit来完成指示所述终端设备TP小于或等于7us;或终端设备可以通过1bit来完成指示所述终端设备TP大于或等于7us。例如,所述第一信息为0时指示所述终端设备TP小于或等于7us,所述第一信息为1时指示所述终端设备TP大于或等于7us。再如,所述第一信息为1时指示所述终端设备TP小于或等于7us,所述第一信息为0时指示所述终端设备TP大于或等于7us。当然,在其他可替代实施例中,所述第一阈值还可以是7us之外的数值,本申请对此不作具体限定。
此外,所述第一信息用于指示所述终端设备的TP小于或等于第一阈值时,所述终端设备的TP可以默认大于缺省下限值。例如,所述缺省下限值可以是0或其他数值。所述第一信息用于指示所述终端设备的TP是否大于或等于所述第一阈值时,所述终端设备的TP可以默认小于缺省上限值。例如,所述缺省上限值可以是预设值,再如,所述缺省上限值可以根据所述第一阈值确定。例如,所述缺省上限值可以是2倍的第一阈值加1。
举例来说,假设所述第一阈值为7us,所述第一信息用于指示所述终端设备的TP小于或等于7us时,网络设备可以确定所述终端设备的TP在0-7us范围内,0-7us范围包括或不包括7us。所述第一信息用于指示所述终端设备的TP是否大于或等于7us阈值时,网络设备可以确定所述终端设备的TP在7-15us范围内,7-15us范围包括或不包括7us。
在一些实施例中,所述第一信息用于在多个候选范围内指示所述终端设备的TP所在的范围。
在一些实施例中,所述多个候选范围通过多个阈值划分。
在一些实施例中,所述多个阈值为预定义的,或所述多个阈值通过所述终端设备进行上报,或所述多个阈值由所述网络设备配置。
示例性地,所述网络设备接收到所述第一信息后,基于所述终端设备的TP所在的范围,确定是否调度终端设备在所述终端设备发生天线转换的时间单元内或在连续的多个时间单元中的每一个时间单元内发送SRS;或者说,所述网络设备可基于所述终端设备的TP所在的范围,确定是否为所述终端设备预留用于所述终端设备进行天线转换的GP。例如,所述网络设备可以承受所述终端设备的TP所在的范围时,所述网络设备可以调度终端设备在所述终端设备发生天线转换的时间单元内或在连续的多个时间单元中的每一个时间单元内发送SRS,即可以不为所述终端设备预留用于所述终端设备进行天线转换的GP;否则,所述网络设备不调度终端设备在所述终端设备发生天线转换的时间单元内或在连续的多个时间单元中的每一个时间单元内发送SRS,即需要为所述终端设备预留用于所述终端设备进行天线转换的GP。
示例性地,所述第一信息可通过至少一个比特位在所述多个候选范围内指示所述终端设备的TP所 在的范围,和/或,所述第一信息可通过所述至少一个个比特位在所述多个候选范围内指示所述终端设备的TP所在的范围。
举例来说,假设所述多个候选范围包括:0-7us、7-15us,此时,终端设备可以通过1bit来完成指示所述终端设备的TP所在的范围。例如,所述第一信息为0时指示所述终端设备的TP所在的范围为0-7us,所述第一信息为1时指示所述终端设备的TP所在的范围为7-15us。再如,所述第一信息为1时指示所述终端设备的TP所在的范围为0-7us,所述第一信息为0时指示所述终端设备的TP所在的范围为7-15us。当然,在其他可替代实施例中,所述多个候选范围还可以是其他数值范围,本申请对此不作具体限定。
示例性地,所述第一信息可以包括多个比特位,所述多个比特位和所述多个阈值一一对应,在这种情况下,所述多个比特位中的每一个比特位的取值用于指示所述终端设备的TP是否大于所述每一个比特位对应的阈值。进一步的,所述终端设备的TP可以默认大于缺省下限值。例如,所述缺省下限值可以是0或其他数值。所述终端设备的TP可以默认小于缺省上限值。例如,所述缺省上限值可以是预设值,再如,所述缺省上限值可以根据所述第一阈值确定。例如,所述缺省上限值可以所述多个阈值的累计和。
举例来说,假设所述第一阈值为5us和10us,所述缺省下限值为0,所述缺省上限值为15;此时,终端设备可以通过2bit来指示所述终端设备的TP是否大于5us以及是否大于10us。例如,若所述第一信息指示所述终端设备的TP不大于5us且不大于10us,则所述终端设备的TP所在的范围为0-5us,0-5us范围包括或不包括5us。若所述第一信息指示所述终端设备的TP大于5us且不大于10us,则所述终端设备的TP所在的范围为5-10us,5-10us范围包括或不包括5us,5-10us范围包括或不包括10us。若所述第一信息指示所述终端设备的TP大于5us且大于10us,则所述终端设备的TP所在的范围为10-15us,10-15us范围包括或不包括10us。
值得注意的是,所述终端设备的TP的长短对网络设备的解调是由直接影响的,且影响的大小跟网络设备的能力有关。解调能力强的网络设备其可以承受的TP更大(也即采用很少的信号就可以完成SRS的解调),而解调能力弱的网络设备能承受的TP则更小(也即需要更多的信号才能完成SRS的解调)。因此,所述多个候选TP、所述第一阈值或所述多个阈值由所述网络设备配置时,能够使得网络设备基于终端设备上报的第一信息确定的所述终端设备的TP能力能够与网络设备可以承受的TP相匹配,进而保证数据传输的可靠性。简言之,终端设备通过所述第一信息在网络设备配置的多个候选TP中指示所述终端设备的TP,或所述终端设备通过所述第一信息指示是否低于网络设备配置的所述第一阈值,或所述终端设备通过所述第一信息在基于网络设备配置的多个阈值划分的多个候选范围内,指示所述终端设备的TP所在的范围,能够使得网络设备基于终端设备上报的第一信息确定的所述终端设备的TP能力能够与网络设备可以承受的TP相匹配,进而保证数据传输的可靠性。
在一些实施例中,所述TP能力为适用于所述终端设备的能力,或所述TP能力为适用于所述终端设备使用的部分子载波间隔SCS或全部SCS的能力。
示例性地,所述第一信息为所述终端设备对应的信息,或所述第一信息为所述终端设备使用的部分SCS或全部SCS对应的信息。换言之,可以针对所述终端设备、所述终端设备使用的部分SCS或全部SCS上报所述终端设备的TP能力。
当然,在其他可替代实施例中,也可以以其他粒度上报所述终端设备的IP能力,本申请对此不作具体限定。
在一些实施例中,所述终端设备的TP为缺省TP。

在一些实施例中,所述缺省TP为所述终端设备采用的频段所对应的TP。
示例性地,针对FR1频段而言,所述缺省TP可以为15us。
当然,在其他可替代实施例中,FR1频段对应的TP也可以是其他数值,本申请对此不作具体限定。
应当理解,所述终端设备是否上报上文涉及的第一信息,可以是通过网络设备指示或激活,也可以是由所述终端设备自行确定,还可以通过所述网络设备和所述终端设备进行协商的方式确定,本申请对此不作具体限定。
图7是本申请实施例提供的无线通信方法300的示意性流程图,所述无线通信方法300可以由终端设备和网络设备交互执行。图7中所示的终端设备可以是如图1所示的终端设备,图7中所示的网络设备可以是如图1所示的接入网设备。
如图7所示,所述方法300可包括以下部分或全部内容:
S310,在第一时间间隔内除至少一个保护时间GP之外的时间单元内,向网络设备发送上行信息;
其中,所述第一时间间隔的时长大于所述至少一个GP的时长,所述第一时间间隔为相邻的两个 SRS资源或资源集合之间的时间间隔,所述至少一个GP包括用于所述终端设备进行至少一次天线切换的时间单元。
本实施例中,在第一时间间隔内除至少一个GP之外的时间单元内,向网络设备发送上行信息,使得终端设备能够合理利用相邻的两个SRS资源或资源集合之间的空闲时间单元,进而能够提升资源利用率以及数据吞吐量。
当然,在其他可替代实施例中,所述终端设备也可以在所述第一时间间隔内除所述至少一个GP之外的时间单元内,接收所述终端设备发送的下行信息;或所述终端设备也可以在所述第一时间间隔内除所述至少一个GP之外的时间单元内,向所述网络设备发送上行信息并接收所述网络设备发送的下行信息,本申请对此不作具体限定。
值得注意的是,本申请利用第一时间间隔内的除所述至少一个GP之外的空闲的时间单元,向网络设备发送上行信息,能够提升资源利用率以及数据吞吐量。
图8是本申请实施例提供的第一时间间隔的示意图。
如图8所示,当相邻的两个SRS的资源或资源集合之间的第一时间间隔(即SRS0的资源或资源集与SRS1的资源或资源集之间的时间间隔)包括5个符号时,若GP长度为1个符号,则GP可选的位置有5个,即S1~S5。这种情况下,如果只考虑了两个SRS的资源或资源集合之间的时间间隔的要求,即需要保证第一时间间隔大于或等于GP,从而终端设备可以在这个间隔内完成天线的切换及功率调整等。进一步的,当第一时间间隔大于GP时,也不能在第一时间间隔内进行数据传输。然而,当第一时间间隔过大时,如果不允许终端设备进行其它信号的发射必然会造成资源浪费并降低了数据吞吐量。结合图8来说,虽然GP仅占用一个符号,但由于网络设备将不去在S1到S5的符号上调度终端设备进行数据发射,由此带来的问题就是会浪费至少4个符号。有鉴于此,本申请请利用第一时间间隔内的除所述至少一个GP之外的空闲的时间单元,向网络设备发送上行信息,能够提升资源利用率以及数据吞吐量。
在一些实施例中,所述方法300还可包括:
终端设备确定所述至少一个GP在所述第一时间间隔内的位置。
示例性地,终端设备确定所述至少一个GP在所述第一时间间隔内的位置,并在所述第一时间间隔内除所述至少一个GP之外的时间单元内,向网络设备发送上行信息。相应的,网络设备确定所述至少一个GP在所述第一时间间隔内的位置,并在所述第一时间间隔内除所述至少一个GP之外的时间单元内,接收所述终端设备发送的上行信息。
值得注意的是,通过限定第一时间间隔需要大于GP,可以使得终端设备可以在所述第一时间间隔内完成天线的切换及功率调整等。但是,如果不确定GP的位置,也就意味着,对于第一时间间隔大于GP的情况下,由于所述网络设备无法确定终端设备的天线切换发生在哪个时间单元上而导致网络设备无法调度终端设备在非用于天线切换的时间单元上来进行数据传输,造成性能下降。有鉴于此,本实施例通过确定所述至少一个GP在所述第一时间间隔内的位置,使得网络设备能够知道在这种情况下终端设备在哪个时间单元上进行天线切换,即所述至少一个GP的位置,由此,就可以充分利用除所述至少一个GP意外的剩余时间单元进行上行信息或下行信息的传输,进而能够保证数据传输的可靠性以及数据传输成功率。
应当理解,本申请对用于所述终端设备进行至少一次天线切换的时间单元的数量不作具体限定。
例如,在一些实施例中,用于所述终端设备进行至少一次天线切换的时间单元可以是一个时间单元,例如,一个符号,也可以是两个时间单元,例如,两个符号,还可以是其他数量个或其他粒度的时间单元。可选的,用于所述终端设备进行至少一次天线切换的时间单元包括多个时间单元时,所述多个时间单元可以是连续的多个时间单元。
在一些实施例中,所述至少一个GP在所述第一时间间隔内的位置为预定义的。
示例性地,所述至少一个GP在所述第一时间间隔内的位置可以预定义为以下中的至少一项:
a)、第一个时间单元;
b)、最后一个时间单元;
c)、中间位置的时间单元;
d)、第一个时间单元和最后一个时间单元;
e)、中间位置的2个时间单元;
其中,a)、b)以及c)适用于只需要进行一次天线切换的场景,d)和e)适用于需要进行两次天线切换的场景,比如从SRS0的发射天线切换到一个性能更好的天线去发射数据之后又切换回SRS1的发射天线继续发射SRS的情况。
图9是本申请实施例提供的终端设备进行单次天线切换时所述至少一个GP在第一时间间隔内的位 置的示意图。
如图9所示,当相邻的两个SRS的资源或资源集合之间的第一时间间隔(即SRS0的资源或资源集与SRS1的资源或资源集之间的时间间隔)包括5个符号时,若GP长度为1个符号,则GP可选的位置有5个。这种情况下,如图9中的(a)所示,可以预定义所述第一时间间隔内的第一个符号为用于所述终端设备进行单次天线转换的GP(即从用于发送SRS0的天线Ant0转换到用于发送SRS1的天线Ant1时使用的GP),如图9中的(b)所示,可以预定义所述第一时间间隔内的最后一个符号为用于所述终端设备进行单次天线转换的GP(即从用于发送SRS0的天线Ant0转换到用于发送SRS1的天线Ant1时使用的GP),如图9中的(c)所示,可以预定义所述第一时间间隔内的中间位置的符号为用于所述终端设备进行单次天线转换的GP(即从用于发送SRS0的天线Ant0转换到用于发送SRS1的天线Ant1时使用的GP);基于此,所述终端设备在剩余的4个符号上可以向网络设备发送上行信息,例如物理上行共享信道(Physical Uplink Shared Channel,PUSCH)。
图10是本申请实施例提供的终端设备进行单次天线切换时所述至少一个GP在第一时间间隔内的位置的示意图。
如图10所示,当相邻的两个SRS的资源或资源集合之间的第一时间间隔(即SRS0的资源或资源集与SRS1的资源或资源集之间的时间间隔)包括5个符号时,若GP长度为1个符号,则GP可选的位置有5个。这种情况下,如图10中的(a)所示,可以预定义所述第一时间间隔内的第一个符号和最后一个符号为用于所述终端设备进行2次天线转换的GP(即从用于发送SRS0的天线Ant0转换到天线Ant1时使用的GP,以及从天线Ant1转换到用于发送SRS1的天线Ant2时使用的GP),如图10中的(b)所示,可以预定义所述第一时间间隔内的中间位置的两侧的符号为用于所述终端设备进行单次天线转换的GP(即从用于发送SRS0的天线Ant0转换到天线Ant1时使用的GP,以及从天线Ant1转换到用于发送SRS1的天线Ant2时使用的GP);基于此,所述终端设备可以在剩余的3个符号上可以向网络设备发送上行信息,例如PUSCH。
当然,在其他可替代实施例中,所述至少一个GP在所述第一时间间隔内的位置也可以预定义为其他位置,例如中间位置的左侧或右侧的时间单元,再如中间位置的左侧间隔至少一个时间单元的1个或2个时间单元,再如中间位置的右侧间隔至少一个时间单元的1个或2个时间单元,本申请对此不作具体限定。
在一些实施例中,所述方法300还可包括:
终端设备向所述网络设备发送第二信息,所述第二信息用于确定所述至少一个GP在所述第一时间间隔内的位置。
换言之,网络设备接收所述终端设备发送的第二信息;所述网络设备收到所述第二信息后,基于所述第二信息确定所述至少一个GP在所述第一时间间隔内的位置;然后可以基于所述至少一个GP在所述第一时间间隔内的位置利用除所述至少一个GP意外的剩余时间单元进行上行信息或下行信息的传输。
在一些实施例中,所述第二信息用于在多个候选位置中指示所述至少一个GP在所述第一时间间隔内的位置。
示例性地,所述第二信息可通过至少一个比特位的取值在多个候选位置中指示所述至少一个GP在所述第一时间间隔内的位置。
