Description
本申请要求2022年3月15日提交中国专利局、申请号为202210253394.6、发明名称为“数据传输方法及装置、计算机可读存储介质”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
本申请涉及通信技术领域,具体地涉及一种数据传输方法及装置、计算机可读存储介质。
随着用户对上行业务需求的快速增长,对网络中的终端设备的上行覆盖率、速率和时延都提出了更高的需求。现有的时分双工(Time Division Duplexing,简称TDD)系统中网络设备在同一时域资源上的传输方向是相同的,例如,网络设备在时隙0上的传输方向为下行,则网络设备在时隙0上只能进行下行通信,无法进行上行通信。对于具有上行业务需求的用户设备(User Equipment,简称UE,也可称为终端设备)而言,这就导致UE无法在时隙0及时传输上行数据。
为满足用户的上行业务需求,一种可能的解决方式是,网络设备在频域上划分用于上行传输的频域资源范围和用于下行传输的频域资源范围,在保证不同UE可以使用不同范围内的频域资源同时进行上下行传输的同时,利用频分减少干扰以降低网络设备的复杂度,也更易于实现。
但是,现有技术仅讨论网络设备侧可能的解决方案,并未考虑UE侧的具体处理逻辑。若UE侧仍沿用现有技术进行数据传输,可能导致不同UE之间、网络设备和UE之间进行数据传输时产生干扰。

本申请实施例提供的方法涉及网络设备和UE,网络设备和UE之间可以进行上下行信号的传输。
本申请实施例的UE是一种具有无线通信功能的设备,可以称为
终端(terminal)、终端设备、移动台(mobile station,MS)、移动终端(mobile terminal,MT)、接入终端设备、车载终端设备、工业控制终端设备、UE单元、UE站、移动站、远方站、远程终端设备、移动设备、UE终端设备、无线通信设备、UE代理或UE装置等。UE可以是固定的或者移动的。需要说明的是,UE可以支持至少一种无线通信技术,例如长期演进(Long Term Evolution,简称LTE)、新空口(new radio,NR)等。例如,UE可以是手机(mobile phone)、平板电脑(pad)、台式机、笔记本电脑、一体机、车载终端、虚拟现实(virtual reality,VR)终端设备、增强现实(augmented reality,AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端、蜂窝电话、无绳电话、会话启动协议(session initiation protocol,SIP)电话、无线本地环路(wireless local loop,WLL)站、个人数字助理(personal digital assistant,PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、可穿戴设备、未来移动通信网络中的终端设备或者未来演进的公共移动陆地网络(public land mobile network,PLMN)中的终端设备等。在本申请的一些实施例中,终端设备还可以是具有收发功能的装置,例如芯片系统。其中,芯片系统可以包括芯片,还可以包括其它分立器件。
本申请实施例中网络设备是一种为UE提供无线通信功能的设备,也可称之为接入网设备、无线接入网(radio access network,RAN)设备、或接入网网元等。其中,网络设备可以支持至少一种无线通信技术,例如LTE、NR等。示例的,网络设备包括但不限于:第五代移动通信系统(5th-generation,5G)中的下一代基站(generation nodeB,gNB)、演进型节点B(evolved node B,eNB)、无线网络控制器(radio network controller,RNC)、节点B(node B,NB)、基站控制器(base station controller,BSC)、基站收发台(base transceiver station,BTS)、家庭基
站(例如,home evolved node B、或home node B,HNB)、基带单元(baseband unit,BBU)、收发点(transmitting and receiving point,TRP)、发射点(transmitting point,TP)、移动交换中心等。网络设备还可以是云无线接入网络(cloud radio access network,CRAN)场景下的无线控制器、集中单元(centralized unit,CU)、和/或分布单元(distributed unit,DU),或者接入网设备可以为中继站、接入点、车载设备、终端设备、可穿戴设备以及未来移动通信中的网络设备或者未来演进的PLMN中的网络设备等。在一些实施例中,网络设备还可以为具有为UE提供无线通信功能的装置,例如芯片系统。示例的,芯片系统可以包括芯片,还可以包括其它分立器件。
如背景技术所言,现有技术在讨论通过允许不同UE同时在不同频域资源进行上下行传输以满足用户的上行业务需求时,仅考虑网络设备侧的处理方式,并未考虑UE侧的具体处理逻辑。
但是对于UE侧而言,UE仍然支持半双工,也即UE在某个时间点只能进行下行接收或上行发送。并且根据现有标准的规定,UE是基于整个频域(如整个部分带宽(Bandwidth Part,简称BWP))进行上行通信或下行通信的,这会在网络设备采用上述解决方式来配置资源并进行数据传输时造成UE和网络设备之间、UE之间的干扰。
例如,从网络设备的角度,网络设备可以在时隙0使用频域资源范围1向UE1发送下行数据,同时使用频域资源范围2接收UE2发送的数据。但是对于UE2而言,由于UE2是基于整个频域进行上行通信的,因而UE2可能在时隙0使用频域资源范围1上传数据,则UE2发送的上行信号将对UE1在频域资源范围1的下行接收产生干扰。这种干扰在UE1和UE2距离很近时变得尤为严重。
为解决上述技术问题,本申请实施例提供一种数据传输方法,包括:网络设备向UE发送第一配置信息,相应的,UE接收第一配置信息,其中,第一配置信息用于配置至少一个频域资源对的频域位置,每一频域资源对包括上行频域资源和下行频域资源,同一个频域资源
对中的上行频域资源和下行频域资源为同一时域资源上的两个频域资源,同一个频域资源对中的上行频域资源和下行频域资源不重叠;UE可以根据第一时间单元的传输方向,在第一时间单元对应的频域资源对中选择上行频域资源或者下行频域资源,并在第一时间单元上传输数据。
本实施方案确保UE能够准确获知上下行传输的频域资源范围,使得UE能够准确使用当前时间单元(即第一时间单元)的传输方向确定该时间单元对应的上行(或下行)频域资源进行上行(或下行)传输,从而避免和其他UE或网络设备产生干扰。具体而言,UE可以基于第一配置信息确定网络设备配置给UE的各频域资源对的具体频域位置。进一步,在第一时间单元上实际进行数据传输时,根据第一配置信息结合第一时间单元的传输方向,选择网络设备在该第一时间单元配置给UE的上行频域资源或下行频域资源传输数据。由此,UE进行数据传输的频域资源能够被精确限定到网络配置给该UE的符合当前传输方向的频域资源上,从而确保不同UE都在各自被配置的特定频域资源上进行数据传输,避免网络设备和UE之间、UE和UE之间进行数据传输时产生干扰。
为使本申请的上述目的、特征和有益效果能够更为明显易懂,下面结合附图对本申请的具体实施例做详细的说明。
图1是本申请一实施例(记为第一实施例)提供的一种数据传输方法的信令交互图。
本实施方案可以应用于数据传输场景,在本场景中,进行数据传输的双方均在配置的频域资源上根据指示的传输方向进行数据传输,以避免干扰。所述干扰的产生原因例如可以是,同一时刻占用配置给其他UE的频域资源或被其他UE占用配置给自己的频域资源传输数据,且其他UE和自己的传输方向相反。
在具体实施中,下述步骤(简称S)101至S103所提供的数据传输方法中,UE执行的动作,可以由UE中的具有数据传输功能的芯
片执行,也可以由UE中的基带芯片执行。网络设备执行的动作,可以由网络设备中的具有数据传输功能的芯片执行,也可以由网络设备中的基带芯片执行。
具体地,参考图1,本实施方案所述数据传输方法可以包括如下步骤:
S101,网络设备(可以记为网络设备12)向UE(可以记为UE11)发送第一配置信息。相应的,UE11从网络设备12接收第一配置信息。
第一配置信息可以用于配置至少一个频域资源对的频域位置,每一频域资源对可以包括上行频域资源和下行频域资源。
在一个具体实施方式中,第一配置信息可以通过无线资源控制(Radio Resource Control,简称RRC)信令承载。
在一个具体实施方式中,上行频域资源可以为上行BWP中的一段或多段频域资源,下行频域资源可以为下行BWP中的一段或多段频域资源。
上行频域资源为上行BWP中的一段频域资源可以指,上行频域资源连续地占据上行BWP的带宽中的一段带宽区间,如图2示出的上行频域资源0和上行频域资源1。上行频域资源为上行BWP中的多段频域资源可以指,上行频域资源不连续地占据上行BWP的带宽中的多段带宽区间。对于上行BWP而言,可以划分得到一个或多个上行频域资源。上行BWP的所有带宽都可以划分从而得到至少一个上行频域资源。或者,可以仅部分上行BWP的带宽被划分成上行频域资源,如图2中上行BWP0的空白部分就是被保留的带宽区间。其中,不同索引的上行频域资源之间可以有部分频域资源重叠,也可以频域资源完全不重叠,本申请不作限制。
网络设备12可以向UE11配置多个上行BWP,其中每一上行BWP均可以划分有至少一个上行频域资源。相应的,第一配置信息可以包括:对于每一上行BWP,所述上行BWP中各上行频域资源的
频域位置和索引(索引也可以称为编号)。不同的上行BWP上的上行频域资源可以各自分别设置索引。例如,上行BWP1上的上行频域资源的索引可以从0开始,上行BWP2上的上行频域资源的索引也可以从0开始。不同的上行BWP上的上行频域资源也可以联合设置索引,例如,上行BWP1上的上行频域资源的索引为0-4,则上行BWP2上的上行频域资源的索引可以从5开始。
需要说明的是,当一个上行BWP仅包括一个上行频域资源时,针对该上行BWP,第一配置信息可以包括也可以不包括该上行频域资源的索引。
示例性的,在指示上行频域资源的频域位置时,可以在BWP上行公共(BWP-UplinkCommon)消息或者BWP上行专有(BWP-UplinkDedicated)消息中增加上行频域资源的配置,如可以在消息中增加上行频域资源添加列表(uplinkSubband-ToAddModList)指示元素(Indicate Element,简称IE),该列表的大小为上行BWP中上行频域资源数量的最大值(maxNrofSubbands),此IE可以包含各个上行频域资源的索引和频域位置。频域位置的配置可以通过资源指示值(Resource Indication Value,RIV)配置一段连续的频域资源,或者通过比特图(bitmap)的形式配置一段或者多段频域资源。
类似的,下行频域资源为下行BWP中的一段频域资源可以指,下行频域资源连续地占据下行BWP的带宽中的一段带宽区间,如图2示出的下行频域资源1。下行频域资源为下行BWP中的多段频域资源可以指,下行频域资源不连续地占据下行BWP的带宽中的多段带宽区间,如图2示出的下行频域资源0。对于下行BWP而言,可以划分得到一个或多个下行频域资源。下行BWP的所有带宽都可以划分从而得到至少一个下行频域资源,如图2所示。或者,可以仅部分下行BWP的带宽被划分成下行频域资源。其中,不同索引的下行频域资源之间可以有部分频域资源重叠(例如图2中的下行频域资源1和下行频域资源0),也可以频域资源完全不重叠,本申请不作限制。
网络设备12可以向UE11配置多个下行BWP,其中每一下行BWP均可以划分有至少一个下行频域资源。相应的,第一配置信息可以包括:对于每一下行BWP,所述下行BWP中各下行频域资源的频域位置和索引。不同的下行BWP上的下行频域资源可以各自分别设置索引。例如,下行BWP1上的下行频域资源的索引可以从0开始,下行BWP2上的下行频域资源的索引也可以从0开始。不同的下行BWP上的下行频域资源也可以联合设置索引,例如,下行BWP1上的下行频域资源的索引为0-4,则下行BWP2上的下行频域资源的索引可以从5开始。当一个下行BWP仅包括一个下行频域资源时,针对该下行BWP,第一配置信息可以包括也可以不包括该下行频域资源的索引。
示例性的,在指示下行频域资源的频域位置时,可以在BWP下行公共(BWP-DownlinkCommon)消息或者BWP下行专有(BWP-DownlinkDedicated)消息中增加下行频域资源的配置,如可以在消息中增加下行频域资源添加列表(DownlinkSubband-ToAddModList)IE,该列表的大小为下行BWP中下行频域资源数量的最大值(maxNrofSubbands),此IE可以包含各个下行频域资源的索引和频域位置。频域位置的配置可以通过RIV配置一段连续的频域资源,或者通过比特图(bitmap)的形式配置一段或者多段频域资源。
在一个具体实施方式中,上行BWP和下行BWP可以配置成BWP对,一个BWP对中的上行BWP和下行BWP可以是在频域上具有交叠的两段频域资源,例如,一个BWP对中的上行BWP可以为下行BWP中的一部分。例如,索引相同的上行BWP和下行BWP可以为一个BWP对。同一BWP对中索引相同的上行频域资源和下行频域资源可以配置为一个频域资源对。例如,继续参考图2,索引为0的下行BWP(记作BWP0)上配置了索引为0的下行频域资源(记作下行频域资源0)和索引为1的下行频域资源(记作下行频域资源1),上行BWP0上配置了索引为0的上行频域资源(记作下行频域资源0)
和索引为1的上行频域资源(记作上行频域资源1)。则下行频域资源0和上行频域资源0为一个频域资源对,下行频域资源1和上行频域资源1为一个频域资源对。
在一个具体实施方式中,同一个频域资源对中的上行频域资源和下行频域资源可以为同一时域资源上的两个频域资源。具体地,同一时域资源可以指相同的时域资源,所述时域资源可以包括一个或多个时间单元对应的资源。所述时间单元可以为UE11和网络设备12在时域上的通信粒度。例如,本申请中的时间单元(例如,第一时间单元)可以为时隙、迷你时隙、子帧、符号、帧等。
进一步,同一个频域资源对中的上行频域资源和下行频域资源不重叠。
由此,可以以一个时间单元内的单个频域资源为粒度配置不同频域资源的传输方向。具体而言,在一个时间单元对应的BWP内可以配置多个频域资源,且不同频域资源配置的传输方向可以不同。对于网络设备12而言,在一个时间单元内,既可以在下行频域资源向UE11发送数据,还可以在上行频域资源接收其他UE发送的数据。例如,在下文中的图5中,在时隙0,网络设备12可以在频域资源对0中的下行频域资源0向UE11发送数据,还可以在频域资源对0中的上行频域资源0接收其他UE发送的数据。
在一个具体实施方式中,同一频域资源对中的上行频域资源和下行频域资源在频域上可以连续也可以不连续。若不连续,则上行频域资源和下行频域资源之间可以存在一个不为0的频域间隔,该频域间隔在上行频域资源与下行频域资源之间形成保护带(guard band),从而可以避免上行频域资源与下行频域资源之间的干扰。例如,参见下文中的图5,频域资源对0中的上行频域资源和下行频域资源之间空白部分即保护带。
在一个具体实施方式中,继续参考图1,本实施方案所述数据传输方法还可以包括步骤:
S102,响应于接收到第一配置信息,UE11确定网络设备12配置给UE11的至少一个频域资源对的频域位置。其中,S102为可选步骤。
具体的,UE11可以根据第一配置信息确定每个BWP对中的频域资源对的频域位置。
例如,可以在BWP下行公共消息或者BWP下行专有消息下新增的频域资源的配置IE中获取各下行频域资源的频域位置和索引。同样的,可以在BWP上行公共消息或者BWP上行专有消息下新增的频域资源的配置IE中获取各上行频域资源的频域位置和索引。
在一个具体实施方式中,继续参考图1,本实施方案所述数据传输方法还可以包括步骤:
S103,UE11根据第一时间单元的传输方向在第一时间单元对应的频域资源对中选择上行频域资源或者下行频域资源,并在第一时间单元上与网络设备12传输数据。例如,假设第一时间单元对应的传输方向为上行,则UE11在执行S103时可以选择第一时间单元对应的频域资源对中的上行频域资源,并在第一时间单元向网络设备12发送数据。又例如,假设第一时间单元对应的传输方向为下行,则UE11在执行S103时可以选择第一时间单元对应的频域资源对中的下行频域资源,并在第一时间单元接收网络设备12发送的数据。
对于网络设备12而言,可以根据各个终端设备在第一时间单元上的传输方向,在第一时间单元对应的所述频域资源对中选择上行频域资源或者下行频域资源,并在第一时间单元上传输数据。例如,结合图2,在第一时间单元,网络设备12既可以在下行频域资源0向UE11发送数据,还可以在上行频域资源0接收其他UE发送的数据。
在一个具体实施方式中,第一配置信息可以包括一个频域资源对,此时所述第一时间单元对应的所述频域资源对为第一配置信息所配置的这个频域资源对。对于配置给UE的多个BWP,第一配置信息可以包括每一BWP上的一个频域资源对,此时第一时间单元对应
的频域资源对为当前被激活的BWP上由第一配置信息配置的这个频域资源对。
在一个具体实施方式中,第一配置信息可以包括多个频域资源对,此时需要确定第一时间单元实际使用的频域资源对。对于配置给UE的多个BWP,第一配置信息可以包括每一BWP上的频域资源对,其中,至少一个BWP上有多个频域资源对,此时第一时间单元对应的频域资源对为当前被激活的BWP上由第一配置信息配置的多个频域资源对中的一个。接下来结合图3对确定第一时间单元实际使用的频域资源对的具体流程进行详细阐述。
具体地,参考图3,图3是本申请另一实施例(记作第二实施例)提供的一种数据传输方法的信令交互图,与上述图1所示第一实施例的区别在于,在本具体实施中,网络设备12在执行S101的同时或之后,还可以执行S104,向UE11发送指示信息,所述指示信息用于确定在所述第一时间单元进行数据传输的频域资源对。响应于接收到指示信息,UE11可以执行S105,在第一时间单元之前从当前所处频域资源对(以下称作源频域资源对)或BWP对切换至指示信息所指示的频域资源对(即目标频域资源对)。此处的指示信息可以为下文中的指示信息1,也可以为下文中的指示信息2。若为下文中的指示信息2,则在传输指示信息2之前,网络设备和UE之间也可以传输下文中的指示信息1,本申请不作限制。在本申请下文中的描述中,若提到指示信息,而未明确说明该指示信息是指示信息1还是指示信息2时,均认为该指示信息既可以是指示信息1也可以是指示信息2。
在一个具体实施中,所述指示信息(记为指示信息1)可以包括初始激活(first active)频域资源对的索引,所述初始激活频域资源对的索引对应的初始激活频域资源对为所述至少一个频域资源对中的一个频域资源对。
具体地,初始激活频域资源对可以是初始激活BWP对上的频域资源对,每一BWP对上均可以配置对应的初始激活频域资源对,当
BWP对变成初始激活BWP对时,该BWP对上配置的初始激活频域资源对即为UE11接下来进行数据传输时使用的频域资源对。所述初始激活BWP对可以由网络设备12通过RRC信令配置(即指示信息1携带在RRC信令中)。
进一步,S105可以包括步骤:在初始接入之后,从初始BWP对切换至初始激活BWP对上的初始激活频域资源对的索引对应的初始激活频域资源对,此时,所述第一时间单元对应的频域资源对为所述初始激活频域资源对。
例如,UE11初始接入网络设备12管理的小区后,可以从初始(initial)BWP对切换至初始激活BWP对,并具体地切换至指示信息1中指示的初始激活BWP对上的初始激活频域资源对的索引对应的初始激活频域资源对。然后,在S103中在第一时间单元上按照指示的传输方向使用初始激活频域资源对中的上行频域资源或下行频域资源和网络设备12传输数据。
在一个具体实施中,指示信息1可以包括默认频域资源对的索引,所述默认频域资源对的索引对应的默认频域资源对为所述至少一个频域资源对中的一个频域资源对。
UE11在至少一个频域资源对中的任一频域资源对,或初始激活频域资源对上进行数据传输期间,当满足资源回退条件时,UE11可以切换至默认频域资源对的索引对应的默认频域资源对,并在接下来使用默认频域资源对和网络设备12继续数据传输。为便于表述,接下来将切换前UE11使用的频域资源对记作源频域资源对。
具体地,默认频域资源对可以是默认BWP对上的频域资源对,默认BWP对可以由网络设备12通过RRC信令配置(即指示信息1携带在RRC信令中)。
进一步,S105可以包括步骤:在满足资源回退条件的情况下,从源频域资源对切换至默认频域资源对的索引对应的默认频域资源
对,此时,所述第一时间单元对应的频域资源对为所述默认频域资源对。
进一步,资源回退条件可以包括非激活定时器(inactivity timer)超时,所述非激活定时器可以由网络设备12通过RRC信令配置。
例如,非激活定时器超时的时候,UE11会回退到默认BWP对上的默认频域资源对。然后,在S103中在第一时间单元上按照指示的传输方向使用默认频域资源对中的上行频域资源或下行频域资源和网络设备12传输数据。
需要说明的是,指示信息1可以包括初始激活频域资源对的索引和/或默认频域资源对的索引,初始激活频域资源对的索引用于指示从初始BWP对切换至其他频域资源对的场景下的目标频域资源对,默认频域资源对的索引用于指示在满足资源回退条件的情况下进行频域资源对切换场景下的目标频域资源对。此时,指示信息1携带在RRC信令中。
如果指示信息1没有指示默认频域资源对,则UE11可以从源频域资源对回退到整个默认BWP对上。然后,按照第一时间单元的传输方向使用默认BWP对中的上行BWP或下行BWP在第一时间单元上传输数据。默认BWP对和指示信息1可以均携带在RRC信令中,也可以携带在不同的消息中,本申请不作限制。
如果RRC信令没有配置默认BWP对,则UE11可以从源频域资源对回退到初始BWP对上。然后,按照第一时间单元的传输方向使用初始BWP对中的上行BWP或下行BWP在第一时间单元上传输数据。
在一个具体实施方式中,指示信息1可以由RRC信令承载。例如,除了前述实施例所述的第一配置信息外,BWP上行公共消息或BWP上行专有消息下新增的频域资源的配置IE中还可以指示初始激活上行频域资源的索引,BWP下行公共消息或BWP下行专有消息下
新增的频域资源的配置IE中还指示初始激活下行频域资源的索引,指示的初始激活上下行频域资源的索引相同(即指示了初始激活频域资源对),从而通过RRC信令配置初始激活频域资源对。
又例如,除了前述实施例所述的第一配置信息外,BWP上行公共消息或BWP上行专有消息下新增的频域资源的配置IE中还可以指示默认上行频域资源的索引,BWP下行公共消息或BWP下行专有消息下新增的频域资源的配置IE中还指示默认下行频域资源的索引,指示的默认上下行频域资源的索引相同(即指示了默认频域资源对),从而通过RRC信令配置默认频域资源对。
再例如,除了前述实施例所述的第一配置信息外,BWP上行公共消息或BWP上行专有消息下新增的频域资源的配置IE中还可以指示初始激活上行频域资源的索引和默认上行频域资源的索引,BWP下行公共消息或BWP下行专有消息下新增的频域资源的配置IE中还指示初始激活下行频域资源的索引和默认下行频域资源的索引,指示的初始激活上下行频域资源的索引相同(即指示了初始激活频域资源对)、默认上下行频域资源的索引相同(即指示了默认频域资源对),从而通过RRC信令配置初始激活频域资源对和默认频域资源对。
在第一个典型的应用场景中,参考图4,假设RRC信令配置初始激活BWP对为BWP对2,默认BWP对为BWP对1,BWP对1上的默认频域资源对和BWP对2上的初始激活频域资源对如图中所示。图4中横坐标为时间(t),纵坐标为频率(f)。
在初始接入后,UE11可以从初始BWP对切换至BWP对2上的上行频域资源和下行频域资源。
切换完成后,UE11可以开启非激活定时器,而当非激活定时器到期时,UE11从初始激活频域资源对切换到BWP对1上的默认频域资源对。
在UE11使用BWP对2上的频域资源对传输数据期间,非激活
定时器可以因接收到新的指示信息(记为指示信息2)而重置(reset)。指示信息2可以用于动态指示频域资源对的索引,接下来将结合图5至图8对基于指示信息2动态切换频域资源对的具体实现方式进行详细阐述。
在一个具体实施方式中,指示信息2可以通过下行控制信息(Downlink Control Information,简称DCI)承载,以指示接下来进行数据传输的频域资源对的索引。例如,可以在DCI中增加频域资源对指示域(indicator),以指示需要切换至的频域资源对的索引。DCI中动态指示的频域资源对的索引对应的频域资源对,为所述至少一个频域资源对中的一个。
进一步,S105可以包括步骤:从源频域资源对切换至指示信息2指示的频域资源对的索引对应的频域资源对,所述第一时间单元对应的频域资源对为所述指示信息2指示的频域资源对。
在一个具体实施方式中,指示信息2指示的频域资源对和源频域资源对可以属于相同BWP对。也就是说,指示信息2触发的频域资源对的切换是在相同BWP内进行的。
具体地,DCI可以包括BWP指示域和频域资源对指示域,若BWP指示域中的BWP对的索引和源频域资源对所在BWP对的索引相同,则可以确定本次切换是在同一BWP对内切换频域资源对,无需切换BWP对。或者,DCI可以仅包括频域资源对指示域,则UE11可以确定本次切换是在同一BWP对内进行的。
例如,参考图5,UE11被配置BWP对0中的频域资源对0和频域资源对1,并且当前使用BWP对0的频域资源对0传输数据。在时隙0,UE11收到DCI 0_1,且DCI 0_1中K2值为3,BWP指示域不变,频域资源对指示域显示频域资源对需要从频域资源对0切换到频域资源对1。则UE11在接收到DCI 0_1的时隙的K2个时隙内切换至频域资源对1,并且在频域资源对1中的上行频域资源上进行上行传输。K2表示从收到DCI到上行发送物理上行共享信道(Physical
Uplink Shared Channel,简称PUSCH)的时间间隔。此时,S103中的第一时间单元可以为时隙3。
又例如,参考图6,UE11被配置BWP对0中的频域资源对0和频域资源对1,并且当前使用BWP对0的频域资源对0传输数据。在时隙0,UE11收到DCI 1_1,且其中K0值为3,BWP指示域不变,频域资源对指示域显示频域资源对需要从频域资源对0切换到频域资源对1。则UE11在接收到DCI 1_1的时隙的K0个时隙内切换至频域资源对1,并且在频域资源1中的下行频域资源上进行下行传输。K0表示从收到DCI到接收物理下行共享信道(Physical Downlink Shared Channel,简称PDSCH)的时间间隔。此时,S103中的第一时间单元可以为时隙3。
在一个具体实施方式中,指示信息2指示的频域资源对和源频域资源对可以属于不同的BWP对。也就是说,指示信息2触发的频域资源对的切换包括BWP对的切换和频域资源对的切换。
具体地,DCI可以包括BWP指示域和频域资源对指示域,若BWP指示域指示的BWP对的索引不同于源频域资源对所在BWP对的索引,则可以确定本次切换需要跨BWP对进行。
例如,参考图7,UE11被配置BWP对0中的频域资源对0和频域资源对1,并且当前使用BWP对0的频域资源对0传输数据。在时隙0,UE11在BWP对0的下行频域资源0收到DCI 0_1,且其中BWP指示域指示的BWP为BWP1,频域资源对指示域指示的频域资源对为频域资源对2,此时频域资源对2为BWP指示域指示的BWP对1上的频域资源对2。则UE11在接收到DCI0_1的时隙的K2个时隙内切换至BWP对1的频域资源对2,并且在频域资源对2中的上行频域资源2进行上行传输。此时,S103中的第一时间单元可以为时隙3。
又例如,参考图8,UE11被配置BWP对0中的频域资源对0和频域资源对1,并且当前使用BWP对0的频域资源对0传输数据。
在时隙0,UE11在BWP对0的下行频域资源0收到DCI 1_1,且其中BWP指示域为BWP1,频域资源对指示域为频域资源对2,此时频域资源对2为BWP指示域指示的BWP对1上的频域资源对2。则UE11在接收到DCI1_1的时隙的K0个时隙内切换至频域资源对2,并且在频域资源对2中的下行频域资源上进行下行传输。此时,S103中的第一时间单元可以为时隙3。
在一个具体实施方式中,DCI中用于指示调度资源的信息域(information field)可以根据源频域资源对和指示信息指示的频域资源对的带宽差异进行调整。
例如,当源频域资源对的带宽小于指示信息所指示的频域资源对的带宽,则前一次发送的DCI中信息域的大小比本次发送所需的信息域要小,此时可以对信息域进行补零到所需信息域大小。假设指示源频域资源对的前一次发送DCI的信息域为5bit,例如为10000,当带宽变大,信息域变大为6bit,则此次DCI的信息域高位补一个0,变为010000。
又例如,当源频域资源对的带宽大于指示信息所指示的频域资源对的带宽,则前一次发送的DCI中信息域的大小比本次发送所需的信息域要大,此时可以从信息域的最低位开始截取所需信息域大小作为信息域取值。假设指示源频域资源对的前一次发送DCI的信息域为6bit,例如111111,若本次指示频域资源对的DCI的信息域只有5bit,则保留低5bit,变为11111。
在一个具体实施方式中,继续参考图3,网络设备12在执行S104的同时或之后,还可以执行S106,向UE11发送第二配置信息,所述第二配置信息用于配置第一时段内各时间单元的传输方向,所述第一时间单元属于所述第一时段。第一时段可以通过UE级时隙配置。其中,第一时间单元可以为第一时段中的任意一个时间单元。
响应于接收到第二配置信息,在S103中,UE11可以根据第二配置信息所指示的第一时间单元的传输方向,选择正确的上行频域资源
或下行频域资源进行传输。
例如,若第二配置信息指示第一时间单元的传输方向为上行,则S103中,UE11选择第一配置信息配置的第一时间单元对应的频域资源对中的上行频域资源向网络设备12发送数据。
此时,网络设备12也根据第一配置信息和第二配置信息在第一时间单元对应的频域资源对中的上行频域资源接收UE11发送的数据。同时,网络设备12还可以在配置给其他UE的第一时间单元对应的频域资源对上和其他UE传输数据。
又例如,若第二配置信息指示第一时间单元的传输方向为下行,则S103中,UE11选择第一配置信息配置的第一时间单元对应的频域资源对中的下行频域资源接收网络设备12发送的数据。
此时,网络设备12也根据第一配置信息和第二配置信息在第一时间单元对应的频域资源对中的下行频域资源向UE11发送数据。同时,网络设备12还可以在配置给其他UE的第一时间单元对应的频域资源对上和其他UE传输数据。
由此,采用本实施方案,确保UE能够准确获知上下行传输的频域资源范围,使得UE能够准确使用当前时间单元(即第一时间单元)的传输方向确定该时间单元对应的上行(或下行)频域资源进行上行(或下行)传输,从而避免和其他UE或网络设备产生干扰。具体而言,UE可以基于第一配置信息确定网络设备配置给UE的各频域资源对的具体频域位置。进一步,在第一时间单元上实际进行数据传输时,根据第一配置信息结合第一时间单元的传输方向,选择网络设备在该第一时间单元配置给UE的上行频域资源或下行频域资源传输数据。由此,UE进行数据传输的频域资源能够被精确限定到网络配置给该UE的符合当前传输方向的频域资源上,从而确保不同UE都在各自被配置的特定频域资源上进行数据传输,避免网络设备和UE之间、UE和UE之间进行传输时产生干扰。
进一步,采用本实施方案的网络设备通过主动发送第一配置信息,向管理的各UE指示进行上下行传输的频域资源范围,使得各UE能够准确使用当前时间单元(即第一时间单元)的传输方向确定该时间单元对应的上行(或下行)频域资源进行上行(或下行)传输,从而避免不同UE之间或UE和自身之间的数据传输产生干扰。具体而言,网络设备可以基于第一配置信息指示配置给UE的各频域资源对的具体频域位置。进一步,在第一时间单元上实际进行数据传输时,根据配置给各UE的第一配置信息结合第一时间单元的传输方向,选择在该第一时间单元配置给各UE的上行频域资源或下行频域资源分别和各UE传输数据。由此,网络设备和特定UE进行数据传输的频域资源能够被精确限定到配置给该特定UE的符合当前传输方向的频域资源上,从而确保不同UE都在各自被配置的特定频域资源上进行数据传输,网络设备站和UE之间、UE和UE之间进行数据传输时的干扰得以被避免。
