Description
本公开涉及通信领域,尤其涉及数据传输方法及装置、存储介质。
对于广覆盖等业务场景,需要较长的CP(Cyclic Prefix,循环前缀)对传输的数据进行加扰或解扰,以便达到保护数据的作用。但是在目前5G(5th Generation Mobile Communication Technology,第5代移动通信技术)NR(New Radio,新空口)系统中,仅60kHz(千赫兹)SCS(Sub-Carrier Spacing,子载波间隔)支持eCP(extended Cyclic Prefix,扩展循环前缀)。且基于协议约定中,CP按照BWP(Bandwith Part,带宽部分)进行配置的,也即BWP只能使用预先配置的一个类型CP进行数据传输。
当MBS(Multicast Broadcast service,组播广播服务)业务或者其他业务需要采用扩展CP进行传输时,仅能在60kHz的BWP上进行传输。与此同时,考虑到该终端需要在具有NCP(Normal Cyclic Prefix,常规循环前缀)的BWP上检测接收广播PDCCH(Physical Downlink Control Channel,物理下行控制信道),广播PDSCH(Physical Downlink Shared Channel,物理下行共享信道),单播PDCCH,单播PDSCH或者Rel-17(Release-17,版本17)MBS相关信道等,终端必须在不同的BWP之间进行切换,从而造成调度的限制和传输的时延。另外,在BWP切换期间,网络侧和终端侧不能进行数据的收发,同样造成了传输时延,降低了系统性能。

这里将详细地对示例性实施例进行说明,其示例表示在附图中。下面的描述涉及附图时,除非另有表示,不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反,它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
在本公开使用的术语是仅仅出于描述特定实施例的目的,而非旨在限制本公开。在本公开和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式,除非上下文清楚地表示其他含义。还应当理解,本文中使用的术语“和/或”是指并包含至少一个相关联的列出 项目的任何或所有可能组合。
应当理解,尽管在本公开可能采用术语第一、第二、第三等来描述各种信息,但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如,在不脱离本公开范围的情况下,第一信息也可以被称为第二信息,类似地,第二信息也可以被称为第一信息。取决于语境,如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
目前协议约定只有SCS为60kHz时能够支持eCP。当SCS为其他数值时,只支持NCP。
参照表1所示,表1示出的是对于常规循环前缀,每个slot(时隙)的OFDM(Orthogonal Frequency Division Multiplexing,正交频分复用)symbol(符号)数、每个frame(帧)的时隙数和每个subframe(子帧)的时隙数。
表1
参照表2所示,表2示出的是扩展循环前缀的每个时隙的OFDM符号数、每个帧的时隙数和每个子帧的时隙数。
表2
另外,目前的协议中还约定,每个BWP只能配置一种CP,配置信令如下:
对于终端而言,广覆盖业务长袖,需要通过配置eCP来支持更大的覆盖半径,如果终端需要同时接收广域覆盖类型业务和传统类型业务,则需要在不同的BWP之间进行切换,例如图1所示,BWP#1支持NCP,BWP#2支持eCP。终端在BWP切换期间,网络侧和终端侧不能进行数据的收发,从而造成了传输时延,降低了系统性能。
考虑到未来移动通信系统中,终端需要同时支持NCP和eCP,本公开提供了以下数据传输方法,可以有效避免终端频繁进行BWP切换所导致的系统性能下降的问题。
下面先从终端侧介绍一下本公开提供的数据传输方法。
本公开实施例提供了一种数据传输方法,参照图2所示,图2是根据一实施例示出的一种数据传输方法流程图,可以用于终端,该方法可以包括以下步骤:
在步骤201中,接收基站发送的指示信息。
在本公开实施例中,该指示信息用于配置指定BWP内不同资源所对应的CP类型。其中,指定BWP可以是需要同时支持多种类型CP的BWP。
在一个可能的实现方式中,多种类型CP包括但不限于NCP和eCP,本公开对此不作限定。
在一个可能的实现方式中,终端侧可以基于以下原因确定某BWP属于指定BWP:
终端需要在该BWP上发送接收广覆盖的业务,例如Rel-18 MBS,因此需要采用eCP进行接收;同时,终端在该BWP上需要发送接收legacy(传统)类型业务,例如Rel-15/16/17的业务,所述业务采用NCP进行发送接收;同时,终端在该BWP上需要接收Rel-15/16/17的broadcast(广播)PDCCH和PDSCH,所述broadcast信道采用NCP进行发送。
在步骤202中,基于所述指示信息,在所述指定BWP的不同资源上使用对应类型CP与所述基站进行数据传输。
上述实施例中,终端侧无需进行BWP切换即可在同一BWP上使用多种类型CP进行数据传输,避免终端频繁进行BWP切换,减少了网络侧的调度限制,减少了数据传输时延,且提高了系统传输性能。
在一些可选实施例中,基站发送的指示信息可以用于配置所述指定BWP内一个或多个特定频域资源所对应的CP类型。即在指定BWP内基于FDM(Frequency Division Multiplexing,频分复用)方式确定CP类型。在一个可能的实现方式中,该指示信息可以用于配置指定BWP内使用扩展循环前缀eCP的频域资源范围。
参照图3所示,图3是根据一实施例示出的一种数据传输方法流程图,可以用于终端,该方法可以包括以下步骤:
在步骤301中,接收基站发送的指示信息。
在本公开实施例中,指示信息可以采用SILV(Start Indication Length Value,起始指示和长度值)的方式配置指定BWP内使用扩展循环前缀eCP的频域资源范围。
具体地,该指示信息可以包括但不限于以下至少一项:所述指定BWP内使用eCP的起始RB(Resource Block,资源块)的RB索引;所述指定 BWP内使用eCP的RB数目。

上述实施例中,可以采用SILV的方式配置指定BWP内使用eCP的起始RB的RB索引以及使用eCP的RB数目中的至少一项,从而确定指定BWP内使用eCP进行数据传输的频域范围,其他RB属于使用NCP进行数据传输的频域范围。实现了在同一BWP上使用多种类型CP进行数据传输的目的,避免终端频繁进行BWP切换,减少了网络侧的调度限制,减少了数据传输时延,且提高了系统传输性能。
在一个可能的实现方式中,该指示信息可以用于配置指定BWP内与eCP对应的anchor(锚)RB。
参照图4所示,图4是根据一实施例示出的一种数据传输方法流程图,可以用于终端,该方法可以包括以下步骤:
在步骤401中,接收基站发送的指示信息。
在本公开实施例中,指示信息可以包括所述锚RB的RB索引。
在步骤402中,在所述指定BWP内预设RB与所述锚RB之间的RB上使用eCP与所述基站进行数据传输;以及在所述指定BWP内的其他RB上使用NCP与所述基站进行数据传输。
在本公开实施例中,预设RB可以是协议预先约定好的指定BWP中的一个RB,或预设RB可以是基站通过信令(或信号)等方式配置的指定BWP中的一个RB。可选地,该预设RB可以为所述指定BWP上的第一个RB或最后一个RB。
终端将预设RB与所述锚RB之间的RB作为使用eCP进行数据传输的频域范围,其他RB作为使用NCP的频域范围。
上述实施例中,同样实现了在同一BWP上使用多种类型CP进行数据传输的目的,避免终端频繁进行BWP切换,减少了网络侧的调度限制, 减少了数据传输时延,且提高了系统传输性能。
在一个可能的实现方式中,指示信息可以用于配置使用不同类型CP的多个CFR(Common Frequency Resources,公共频率资源)。
参照图5所示,图5是根据一实施例示出的一种数据传输方法流程图,可以用于终端,该方法可以包括以下步骤:
在步骤501中,接收基站发送的指示信息。
在本公开实施例中,该指示信息可以包括但不限于以下至少一项:CFR配置信息;与所述CFR对应的CP类型指示信息。
需要说明的是,在本公开实施例中,CFR可以用于组播或广播相关信道的传输,例如可以用于传输MBS业务。本公开对于CFR的配置不作限制。
在步骤502中,在所述指定BWP的不同CFR上,使用所述CP类型指示信息所指示的CP与所述基站进行数据传输。
例如,基站通过指示信息配置了CFR#1和CFR#2,对应的CP类型指示信息分别指示了eCP、NCP,则终端在指定BWP内的CFR#1上使用eCP与基站进行数据传输,在指定BWP内的CFR#2上使用NCP与基站进行数据传输。
上述实施例中,实现了在同一BWP上使用多种类型CP进行数据传输的目的,避免终端频繁进行BWP切换,减少了网络侧的调度限制,减少了数据传输时延,且提高了系统传输性能。
在另一个可能的实现方式中,指示信息可以用于配置所述指定BWP内不同频域资源粒度所对应的CP类型。
需要说明的是,终端可以基于协议约定,确定每个频域资源粒度包含的RB,或者,终端可以基于基站发送的指定信令确定每个频域资源粒度包含的RB。
指定信令可以包括但不限于RRC(Radio Resource Control,无线资源控制)信号、系统消息、MBS-MCCH(MBMS Control Channel,多媒体广 播组播控制信道)等。其中,系统消息可以为SIB1或SIBx,本公开对此不作限定。
其中,指定信令中可以采用显式方式直接指示每个频域资源粒度包含的RB。或者,指定信令中可以采用隐式方式指示每个频域资源粒度包含的RB,本公开对此不作限定。
进一步地,每个频域资源粒度可以包括一个RB,或者可以包括多个RB,多个RB可以为多个连续RB或多个离散RB。
参照图6所示,图6是根据一实施例示出的一种数据传输方法流程图,可以用于终端,该方法可以包括以下步骤:
在步骤601中,接收基站发送的指示信息。
在本公开实施例中,指示信息可以为bitmap(比特图)信息。其中,bitmap信息可以为基于BWP级别配置的,或者基于CFR级别配置的,即基站针对每个指定BWP配置对应的bitmap信息,或者基站针对每个指定BWP内的每个CFR配置对应的bitmap信息,本公开对此不作限定。
在步骤602中,在所述指定BWP内与第一比特值对应的频域资源粒度上使用eCP与所述基站进行数据传输;以及在所述指定BWP内与第二比特值对应的频域资源粒度上使用NCP与所述基站进行数据传输。
在本公开实施例中,第一比特值可以为1,相应地,第二比特值可以为0。或者,第一比特值为0,第二比特值为1。
例如,指示信息为1001,第一比特值为1,第二比特值为0,终端可以在指定BWP的第一个、第四个频域资源粒度上使用eCP与基站进行数据传输,在第二个、第三个频域资源粒度上使用NCP与基站进行数据传输。
上述实施例中,实现了在同一BWP上使用多种类型CP进行数据传输的目的,避免终端频繁进行BWP切换,减少了网络侧的调度限制,减少了数据传输时延,且提高了系统传输性能。
需要说明的是,上述实施例中,eCP也可以替换为NCP,终端基于该指示信息与基站进行数据传输的方式与上述实施例的具体过程类似,在此 不再赘述。
在一些可选实施例中,该指示信息可以用于配置所述指定BWP内一个或多个特定时域资源所对应的CP类型。即在指定BWP内基于TDM(Time Division Multiplexing,时分复用)方式确定CP类型。

在本公开实施例中,第一比特值可以为1,相应地,第二比特值可以为0。或者,第一比特值为0,第二比特值为1。
例如,指示信息为1001,第一比特值为1,第二比特值为0,终端可以在指定BWP的第一个、第四个时域资源上使用eCP与基站进行数据传输,在第二个、第三个时域资源上使用NCP与基站进行数据传输。时域资源的大小可以以OFDM符号、slot(时隙)或预定义的时间长度作为单位,本公开对此不作限定。

为了便于理解,对上述数据传输方法进一步举例说明如下。
实施例1,假设终端需要在同一个频段内同时支持NCP和eCP。作为一个例子,终端出于如下原因确定指定BWP:

实施例3,假设终端需要在同一个频段内同时支持NCP和eCP。作为一个例子,终端出于如下原因确定指定BWP:
终端在该BWP上需要发送接收广覆盖的业务,例如Rel-18 MBS,因此需要采用eCP进行接收;同时,终端在该BWP上需要发送接收legacy业务,例如Rel-15/16/17的业务,所述业务采用NCP进行发送接收;同时,终端在该BWP上需要接收Rel-15/16/17的broadcast PDCCH和PDSCH,所述broadcast信道采用NCP进行发送。
在本公开实施例中,基站通过指示信息为终端的指定BWP配置多种类型CP。具体地,基站可以向终端发送包括指示信息的RRC信号、SIB1、SIBx、MBS-MCCH。该指示信息为BWP级别或者cell级别,本公开对此不做限定。
终端侧接收网络侧发送的指示信息,指示信息用于配置使用不同类型 CP的多个公共频率资源CFR。具体地,指示信息包括但不限于以下至少一项:CFR配置信息;与所述CFR对应的CP类型指示信息。
需要说明的是,CFR用于组播或广播相关信道的传输,例如可以用于传输MBS业务。终端在所述指定BWP的不同CFR上,使用所述CP类型指示信息所指示的CP与所述基站进行数据传输。
参照图12所示,基站为终端在指定BWP内配置了CFR#1和CFR#2,其中CFR#1采用NCP进行数据传输,CFR#2采用eCP进行数据传输。
需要注意的是,本公开对于CFR的配置没有任何限制。
实施例4,假设终端需要在同一个频段内同时支持NCP和eCP。作为一个例子,终端出于如下原因确定指定BWP:
终端在该BWP上需要发送接收广覆盖的业务,例如Rel-18 MBS,因此需要采用eCP进行接收;同时,终端在该BWP上需要发送接收legacy业务,例如Rel-15/16/17的业务,所述业务采用NCP进行发送接收;同时,终端在该BWP上需要接收Rel-15/16/17的broadcast PDCCH和PDSCH,所述broadcast信道采用NCP进行发送。
在本公开实施例中,基站通过指示信息为终端的指定BWP配置多种类型CP。具体地,指示信息用于配置所述指定BWP内不同频域资源粒度所对应的CP类型。指示信息可以为比特图bitmap信息。
所述bitmap中的比特位的比特值为0时,其频域资源粒度对应的CP类型为NCP,当所述bitmap中的比特位的比特值为1时,其频域资源粒度对应的CP类型为eCP。所述bitmap中的每个bit位对应的频域资源粒度为1个RB或N个RB,其中N为大于1的正整数。N个RB可以为连续RB或离散RB。N的取值可以通过基站发送的显式信令进行指示,或者通过协议预定义的方式确定。
参照图13所示,假设指示信息对应的bitmap长度为4bit,也即所述bitmap可指示BWP内4个频域资源粒度对应的CP类型,假设bitmap为1010,其中第一个、第三个频域资源粒度对应的CP类型为eCP,第二个、 第四个频域资源粒度对应的CP类型为NCP。
实施例5,假设终端需要在同一个频段内同时支持NCP和eCP。作为一个例子,终端出于如下原因确定指定BWP:
终端在该BWP上需要发送接收广覆盖的业务,例如Rel-18 MBS,因此需要采用eCP进行接收;同时,终端在该BWP上需要发送接收legacy业务,例如Rel-15/16/17的业务,所述业务采用NCP进行发送接收;同时,终端在该BWP上需要接收Rel-15/16/17的broadcast PDCCH和PDSCH,所述broadcast信道采用NCP进行发送。
在本公开实施例中,基站通过指示信息为终端的指定BWP配置多种类型CP。具体地,指示信息用于配置所述指定BWP内一个或多个特定时域资源所对应的CP类型。
其中,指示信息用于配置所述指定BWP内每个时域资源所对应的CP类型。所述一个或多个特定时域资源的大小以正交频分复用OFDM符号、时隙或预定义的时间长度作为单位。
假设每个特定时域资源以OFDM符号为单位,指示信息为bitmap信息。所述bitmap中的比特位的比特值为0时,其OFDM符号上对应的CP类型为NCP,当所述bitmap中的比特位的比特值为1时,其OFDM符号上对应的CP类型为eCP。
假设基站指示的bitmap为00011000001100,其对应使用的CP类型参照图14A所示。
或者指示信息包括以下至少一项:所述指定BWP内使用eCP的起始时域资源的时域资源索引;所述指定BWP内使用eCP的时域资源数目。
假设时域资源以为OFDM符号为单位,则起始OFDM符号的符号索引为3,符号数目为4,参照图14B所示,从OFDM符号#3到OFDM符号#6上使用eCP与基站进行数据传输,其他OFDM符号上使用NCP与基站进行数据传输。
实施例6,如实施例5所述,终端接收基站发送的CP类型指示信息, 确定指定BWP在一个或多个特定时域资源上的CP类型。具体地,指示信息可以包括以下至少一项:周期信息;每个周期内每个所述时域资源所对应的CP类型指示信息。其中,一个或多个特定时域资源的大小以正交频分复用OFDM符号、时隙或预定义的时间长度作为单位。
预定义的时间长度所包含的时域资源数目可以通过如实施例5中所述的任一信令进行指示。
在本公开实施例中,假设所述指示信息用于指示采用eCP的slot或者时间长度,其余没有指示的slot或者时间长度采用NCP。具体地,基站指示所述eCP时域图样的周期,并指示周期内采用eCP的slot或者时间长度。在一个图样周期内指示eCP所占时域资源的方法参照图15A至图15B所示,分别为在一个周期T内基于bitmap方式进行指示,以及在一个周期T内基于SILV方式进行指示,此处不再赘述。
上述实施例中,可以由基站为终端的指定BWP配置多种类型CP,其中,指定BWP是需要同时支持多种类型CP的BWP。终端侧无需进行BWP切换即可在同一BWP上使用多种类型CP进行数据传输,避免终端频繁进行BWP切换,减少了网络侧的调度限制,减少了数据传输时延,且提高了系统传输性能。
