Description

数据传输方法及装置、存储介质 技术领域
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。
背景技术
在Rel-18(Release-18,版本18)duplex(全双工)enhancement(增强)项目中,对如何实现基站侧的duplex操作进行研究。对于Rel-18duplex基站,其可在semi-static flexible symbol(半静态可变符号)上同时调度不同的终端进行上行和下行传输,具体地可通过如下任意一种方式实现:
第一种方式,通过显式信令在semi-static flexible symbol上配置UL subband(UpLink subband,上行子带)或者DL subband(DownLink subband,下行子带)。其中,UL subband和DL subband分别用于上行传输和下行传输。
第二种方式,通过调度的方式指示duplex终端在所述semi-static flexible symbol上进行发送或者接收,也即此时全双工操作对于duplex终端是透明的。
对于semi-static flexible symbol,基站可进一步的通过SFI(Slot Format Indication,时隙格式指示符)进行传输方向的变更,例如将semi-static flexible symbol指示为DL、UL或者dynamic flexible(动态可变)。
此时SFI指示的传输方向有可能与基站为duplex终端指示或者配置的传输方向不同。如何处理SFI和基站指示的传输方向冲突的问题,目前并没有相关解决方案。

具体实施方式
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”。
Rel-18 duplex enhancement项目中将对全双工方案进行研究,具体地,网络侧设备能够在一个slot(时隙)内同时进行数据的接收和发送。作为一种可能的方案,网络在semi-static flexible符号上调度或者指示全双工终端进行数据的发送或者接收。但是对于semi-static flexible符号而言,网络侧可通过SFI指示其传输方向为UL、DL或者dynamic flexible。当SFI指示的传输方向与基站指示的数据/信号传输方向发生冲突时,终端如何处理当前并没有明确的方案。
在NR(New Radio,新空口)系统中,基站通过SIB1(System Information Block1,系统信息块1)携带tdd-UL-DL-ConfigurationCommon(上下行时分双工通用配置),从而配置小区级别的TDD(Time Division Duplex,时分双工)UL-DL configuration(配置)。额外的,如果基站配置了RRC(Radio Resource Control,无线资源控制)signaling(信号)携带的tdd-UL-DL-ConfigurationDedicated(上下行时分双工专用配置),则TDD UL-DL configuration可以由两者共同确定。所述TDD UL-DL configuration包含如下类型的时域资源:半静态DL symbol;半静态UL symbol;半静态flexible symbol。
其中半静态DL symbol和半静态UL symbol的传输方向不能变更,而半静态flexible symbol可以通过SFI动态的调整传输方向,例如指示为UL、DL或者flexible。
在协议中,对于SFI指示的传输方向,有如下定义:
对于SFI指示的UL symbol,终端不期待基站调度的传输方向与之冲突,且只期待在其上传输上行;
对于SFI指示的DL symbol,终端不期待基站调度的传输方向与之冲突,且只期待在其上接收下行;
对于SFI指示的flexible symbol,终端在接收到基站指示之前不期待在其上进行任 何发送接收。
如果SFI指示的传输方向与基站为duplex终端指示或者配置的传输方向不同,目前并没有相关解决方案。
为了解决上述技术问题,本公开提供了一种数据传输方向、装置及存储介质。下面先从终端侧介绍一下本公开提供的数据传输方法。

下面对本公开提供的数据传输方法进一步举例说明如下。
实施例1,假设终端为Rel-18及后续版本终端,具有半双工能力或者具有全双工能力,本公开不做任何限定。假设基站在TDD频段的semi-static fexible符号上执行全双工操作,也即同时进行调度下行数据和上行数据。第一时间单元为semi-static flexible symbol,可以通过基站发送的以下信息来确定:
tdd-UL-DL-ConfigurationCommon;
tdd-UL-DL-ConfigurationCommon、tdd-UL-DL-ConfigurationDedicated。
基站通过如下两种方式指示终端在所述semi-static flexible符号上的传输方向,本公开实施例不做任何限制:
基站为所述终端配置第一子带的第一数据传输方向,即配置UL subband或者DL subband。在所述UL subband内,终端只能进行上行发送;在所述DL subband内,终端只能进行上行接收。基站在所述UL subband或者DL subband内进行数据信道的调度或者参考信号的指示。
基站通过调度信息或者高层配置指示终端在所述semi-static symbol上进行发送或者接收。基站不需要为所述终端显式的配置UL subband或者DL subband。
进一步的,基站通过SFI指示所述semi-static flexible symbol的传输方向,也即根据业务状况或者干扰状况,将所述semi-static flexible symbol指示为DL、UL或者dynamic flexible。
在本公开实施例中,假设基站通过TDD UL-DL configuration配置的时隙结构为DFFFF,也即在TDD配置周期内,第一个slot为DL slot,剩余的4个slot为flexible slot,参照图9A所示。当然,本公开实施例提供的方法也可直接应用于其他的TDD UL DL时隙结构,本公开对此不作限定。
在本公开实施例中,假设基站在所述semi-flexible symbol上的UL subband上调度了上行传输,即在图9A所示的后4个slot上,配置了上行子带,参照图9B所示。需要注意的是,所述上行传输可以为上行数据,或者上行参考信号,本申请亦不做任何限制。
假设所述基站通过SFI指示所述semi-static flexible symbol为DL symbol或者flexible symbol,则终端忽略所述SFI指示,仍然按照基站的调度在所述UL subband内进行上行传输。此时基站不能在所述UL subband内为所述终端调度下行传输。
参照图10所示,基站发送的SFI指示的第二数据传输方向为:DDDSU。即基站通过SFI将后4个slot对应的第二数据传输方向此时,分别指示为下行、下行、可变、上行。而之前基站在后4个可变slot上配置了上行子带(参照图9B所示)。可以看出,除了最后一个可变slot之外,其他3个可变slot上第一数据传输方向与第二数据传输方向均不同。此时,终端可以忽略SFI的指示,以及按照第一数据传输方向在上行子带上发送数据。参照图10所示,终端仍然在其他3个可变slot的上行子带上发送数据,基站在对应的上行子带上接收数据。
需要说明的是,所述SFI指示的DL symbol或者flexible symbol与终端在UL subband内的上行传输部分或者完全重合,本公开对此不做限定。
实施例2,如实施例1所述,基站发送的SFI指示的传输方向与在semi-static flexible symbol上的DL subband发生了冲突。
假设所述基站通过SFI指示所述semi-static flexible symbol为UL symbol或者flexible symbol,则终端忽略所述SFI指示,仍然按照基站的调度在所述DL subband内接收数据,基站则在该DL subband内发送数据。此时基站不能在所述DL subband内为所述终端调度上行传输。
实施例3,实施例1,假设终端为Rel-18及后续版本终端,具有半双工能力或者具有全双工能力,本公开不做任何限定。假设基站在TDD频段的semi-static fexible符号上执行全双工操作,也即同时进行调度下行数据和上行数据。第一时间单元为semi-static flexible symbol,可以通过基站发送的以下信息来确定:
tdd-UL-DL-ConfigurationCommon;
tdd-UL-DL-ConfigurationCommon、tdd-UL-DL-ConfigurationDedicated。
基站通过如下两种方式指示终端在所述semi-static flexible符号上的传输方向,本公开实施例不做任何限制:
基站为所述终端配置第一子带的第一数据传输方向,即配置UL subband或者DL subband。在所述UL subband内,终端只能进行上行发送;在所述DL subband内,终端只能进行上行接收。基站在所述UL subband或者DL subband内进行数据信道的调 度或者参考信号的指示。
基站通过调度信息或者高层配置指示终端在所述semi-static symbol上进行发送或者接收。基站不需要为所述终端显式的配置UL subband或者DL subband。
进一步的,基站通过SFI指示所述semi-static flexible symbol的传输方向,也即根据业务状况或者干扰状况,将所述semi-static flexible symbol指示为DL、UL或者dynamic flexible。
在本公开实施例中,假设基站通过TDD UL-DL configuration配置的时隙结构为DFFFF,也即在TDD配置周期内,第一个slot为DL slot,剩余的4个slot为flexible slot,参照图9A所示。当然,本公开实施例提供的方法也可直接应用于其他的TDD UL DL时隙结构,本公开对此不作限定。
在本公开实施例中,假设基站在所述semi-flexible symbol上的UL subband上调度了上行传输,即在图9A所示的后4个slot上,配置了上行子带,参照图9B所示。需要注意的是,所述上行传输可以为上行数据,或者上行参考信号,本申请亦不做任何限制。
假设所述基站通过SFI指示所述semi-static flexible symbol为DL symbol或者flexible symbol,则终端忽略所述基站的配置或指示的所述UL subband内的传输。也即终端按照基站发送的SFI的指示确定数据传输方向。此时基站不能在所述UL subband占据的资源内调度下行传输。
参照图11所示,基站发送的SFI指示的第二数据传输方向为:DDDSU。即基站通过SFI将后4个slot对应的第二数据传输方向分别指示为下行、下行、可变、上行。而之前基站在后4个可变slot上配置了上行子带(参照图9B所示)。可以看出,除了最后一个可变slot之外,其他3个可变slot上第一数据传输方向与第二数据传输方向均不同。此时,终端可以按照SFI指示的第二数据传输方向执行数据传输,丢弃基站在第一子带上配置的数据传输,参照图11所示,除了最后一个可变slot之外,终端在其他3个slot上的数据传输方向分别为下行、下行、可变。当然,最后1个符号的数据传输方向为上行,该符号上的上行子带可以保留。
实施例4,如实施例3所述,基站发送的SFI指示的传输方向与在semi-static flexible symbol上的DL subband发生了冲突。假设所述基站通过SFI指示所述semi-static flexible symbol为UL symbol或者flexible symbol,则终端忽略所述基站调度在所述DL subband内的下行接收。此时基站能够在所述DL subband占据的资源内为所述终端调度上行传输。
实施例5,假设终端为Rel-18及后续版本终端,具有半双工能力或者具有全双工能力,本公开不做任何限定。假设基站在TDD频段的semi-static fexible符号上执行全双工操作,也即同时进行调度下行数据和上行数据。第一时间单元为semi-static flexible symbol,可以通过基站发送的以下信息来确定:

tdd-UL-DL-ConfigurationCommon、tdd-UL-DL-ConfigurationDedicated。
基站通过如下两种方式指示终端在所述semi-static flexible符号上的传输方向,本公开实施例不做任何限制:
基站为所述终端配置第一子带的第一数据传输方向,即配置UL subband或者DL subband。在所述UL subband内,终端只能进行上行发送;在所述DL subband内,终端只能进行上行接收。基站在所述UL subband或者DL subband内进行数据信道的调度或者参考信号的指示。
基站通过调度信息或者高层配置指示终端在所述semi-static symbol上进行发送或者接收。基站不需要为所述终端显式的配置UL subband或者DL subband。
进一步的,基站通过SFI指示所述semi-static flexible symbol的传输方向,也即根据业务状况或者干扰状况,将所述semi-static flexible symbol指示为DL、UL或者dynamic flexible。
在本公开实施例中,假设基站通过TDD UL-DL configuration配置的时隙结构为DFFFF,也即在TDD配置周期内,第一个slot为DL slot,剩余的4个slot为flexible slot,参照图9A所示。当然,本公开实施例提供的方法也可直接应用于其他的TDD UL DL时隙结构,本公开对此不作限定。
在本公开实施例中,假设基站在所述semi-flexible symbol上的UL subband上调度了上行传输,即在图9A所示的后4个slot上,配置了上行子带,参照图9B所示。需要注意的是,所述上行传输可以为上行数据,或者上行参考信号,本申请亦不做任何限制。
假设所述基站通过SFI指示所述semi-static flexible symbol为的传输方向与所述终端的子带传输方向不同,则终端通过如下方式确定在所述subband内的相关行为:
如果在所述semi-static flexible symbol上的UL subband或者DL subband内传输的信道或信号,即第一信息为半静态配置的,第一信息可以WieSPS PDSCH,CG PUSCH,periodic SRS,periodic CSI RS等,则duplex终端按照SFI指示的方向确定传输方向。如果所述SFI指示的方向与半静态传输方向不同,则终端忽略或者丢弃所述半静态传输。对应地,基站不期待接收所述半静态上行传输或者发送所述半静态下行传输。
如果在所述semi-static flexible symbol上的UL subband或者DL subband内传输的信道或者信号为基站通过动态信令进行指示的,则duplex终端忽略SFI并按照基站的动态指示传输对应的信道或者信号。其中,所述动态信令为DCI或者MAC CE。
实施例6,如实施例1-实施例5所述,本公开对于SFI与确定semi-static flexible symbol上subband的信令之间的时序关系不做任何限定。
