Description

数据传输方法、设备及存储介质 技术领域
本申请实施例涉及通信技术,尤其涉及一种数据传输方法、设备及存储介质。
背景技术
为了提高5G新空口(New Radio,NR)系统中高频带的上行覆盖,引入了补充上行链路(Supplementary Uplink,SUL)。例如将LTE部分频段作为SUL。由于频段越高,信号传输损耗越大,而且由于终端设备的上行功率受限,所以上行覆盖会受限,因此利用LTE部分频段(相对频率较低)作为补充上行,可以提高上行覆盖。
相关技术中,终端设备是根据参考信号接收功率(Reference Signal Received Power,RSRP)确定选择正常上行链路(Normal Uplink,NUL)还是SUL进行上行传输的。具体的,若RSRP大于门限X,则终端设备选择NUL进行上行传输,否则终端设备选择SUL进行上行传输(除非动态调度指示,即若通过DCI指示使用NUL或SUL)。未来网络部署中会引入基于NR的机器类通信(Machine-Type Communication,MTC)终端设备,其应用场景包括工业传感器网络(industrial wireless sensor network,IWSN),可穿戴设备和视频监控等。这些海量终端设备的引入将对小区上行容量造成冲击,若仅按照RSRP确定传输上行数据的载波,可能导致一定时间或条件下一个载波的负荷很重,因此需要一种合理的确定上行传输的载波的方式。

当前,随着人们对速率、延迟、高速移动性、能效的追求以及未来生活中业务的多样性、复杂性,为此3GPP国际标准组织开始研发5G。5G的主要应用场景包括:增强移动超宽带(eMBB)、低时延高可靠通信(URLLC)、大规模机器类通信(mMTC)。
5G新空口NR系统也可以独立部署,5G网络环境中为了降低空口信令和快速恢复无线连接,快速恢复数据业务的目的,定义了一个新的无线资源控制(Radio Resource Control,RRC)状态,即RRC_INACTIVE状态。这种状态有别于RRC_IDLE和RRC_ACTIVE状态。
RRC_IDLE状态是指:移动性为基于终端设备的小区选择重选,寻呼由核心网(Core Network,CN)发起,寻呼区域由CN配置。网络设备侧不存在终端设备接入层(Access Stratum,AS)上下文。不存在RRC连接。
RRC_CONNECTED状态是指:存在RRC连接,网络设备和终端设备存在终端设备AS上下文。网络侧知道终端设备的位置是具体小区级别的。移动性是网络侧控制的移动性。终端设备和网络设备之间可以传输单播数据。
RRC_INACTIVE状态是指:移动性为基于终端设备的小区选择重选,存在CN-NR之间的连接,终端设备AS上下文存在某个基站上,寻呼由无线接入网络(Radio Access Network,RAN)触发,基于RAN的寻呼区域由RAN管理,网络侧知道终端设备的位置是基于RAN的寻呼区域级别的。
在3GPP R17中NR系统中引入NR-light的设备,目前NR-light的设备主要包括以下三个场景:
工业无线传感器(Industrial Wireless Sensors):和URLLC相比,工业无线传感器具有相对低要求的时延和可靠性。同时工业无线传感器的成本和功耗也比URLLC和eMBB要低。
视频监控(Video surveillance),主要用在智慧城市,工业工厂等视讯监控。智慧城市中数据收集和处理,以便于更有效的进行城市资源的监测和控制,给城市居民提供更有效的服务。
可穿戴设备(Wearables)。包括智能手表,电子健康设备以及一些医疗监测设备等。这些设备的一个共性就是小尺寸的设备。
上述三种场景的共性需求:
设备成本:和R15/16 eMBB相比,要求更低的设备成本和复杂度。基本共识是降低带宽和接收天线。
设备尺寸:比较小的设备尺寸。
覆盖:要求达到与R15/16 eMBB相当的覆盖,如果由于降低接收天线,降低带宽,降低功率等级或者其他降低终端设备复杂度带来的覆盖损失需要补偿。
针对上述三种场景,还有一个不同场景,不同的需求。
工业无线传感器:可靠性99.99%,端到端时延100ms。Bit速率需求2Mbps。设备静止不动。电池寿命是几年。对于安全相关的传感器,时延需求为5-10ms。
视频监控:Bit速率需求2-4Mbps,时延需求<500ms,可靠性需求99.0%-99.9%。对于某些高端视频速率2-4Mbps。上行业务量比较大。
可穿戴设备:参考LTE等级Cat 4,速率150Mbps/50Mbps.
为了提高5G新空口NR系统中高频带的上行覆盖,引入了补充上行SUL。例如将LTE部分频段作为SUL。
SUL、NUL和一个下行链路(Down Link,DL)属于同一个小区,在同一时刻最多只存在一个物理上行共享信道(Physical Uplink Shared Channel,PUSCH)传输;
除非网络侧明确指示终端设备使用哪个UL,否则终端设备根据测量门限判决UL的选择。该门限在系统广播里面广播配置。两个UL之间的载波(两个UL即SUL和NUL)可以通过DCI指示进行动态切换。
RRC_IDLE状态或RRC_INACTIVE状态通过服务小区RSRP大小来决定是使用UL还是SUL来进行初始接入。
未来网络部署中会引入基于NR的MTC终端,其应用场景包括工业传感器网络、可穿戴设备和视 频监控等。这些海量终端的引入将对小区上行容量造成冲击,例如为了提高小区上行容量,设计一种场景,即包括NUL和至少一个SUL,此时仅按照RSRP确定传输上行数据的载波可能导致一定时间或条件下一个载波的负荷很重,某些SUL的载波可能无法选择,因此需要一种合理的确定上行传输的载波的方式。
终端设备利用UL授权grant资源进行数据传输。UL grant资源可以包括:动态授权(Dynamic grant,DG)资源,也可以为配置的授权(Configured grant,CG)资源。网络侧通过动态的下行控制信息(Downlink Control Information,DCI)调度DG资源,通过高层信令(如RRC)配置CG资源。目前有两种类型的CG资源,type1CG资源(RRC配置后方可使用)和type 2 CG资源(RRC配置且通过DCI激活后方可使用)。
在Rel-15,type1 CG资源仅可以配置在SUL上,或者NUL上,即两个UL不能同时配置type1 CG资源,对于type2 CG资源类似。此外,一个服务小区上仅配置type1 CG资源或type2 CG资源,即type1 CG资源和type2 CG资源也不能同时配置。而在Rel-16这一限制被打破,即一个服务小区一个BWP可以同时配置type1 CG资源和type2 CG资源。即现有技术中也不存在CG资源传输切换的问题。而现在,这一限制将被打破。由于NUL和SUL都有可能配置CG资源(如NUL配置type1 CG资源,SUL配置Type 2CG资源),这就涉及CG传输切换的问题,以及切换后原载波的CG是否还能传输的问题。
下面对本申请提供的通信方法进行说明。
图1为本申请实施例所应用的一种通信系统的示意图。如图1所示,该通信系统中至少包括网络设备11和终端设备12。可以理解的是,在实际通信系统中,网络设备11以及终端设备12均可以有一个或多个,该图1仅以一个作为示例。
在图1中,网络设备11可以是接入网设备,例如可以是LTE网络及其演进网络中的接入设备,例如演进型基站(Evolutional Node B,简称eNB或eNodeB),或者也可以包括5G NR系统中的下一代节点B(next generation node B,gNB),或者中继站,或者未来新的网络系统中的基站等等。
终端设备12,也可以称为移动终端、用户设备(User Equipment,简称:UE)、接入终端、用户单元、用户站、移动站、移动台、用户终端、终端、无线通信设备、用户代理或用户装置。具体可以是智能手机、蜂窝电话、无绳电话、个人数字处理(Personal Digital Assistant,简称:PDA)设备、具有无线通信功能的手持设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备等。在本申请实施例中,该终端设备具有与网络设备进行通信的接口。

另一种方式:NUL对应的优先选择参数为第一参数a,则至少一个SUL各自对应的优先选择参数分别为(1-a)/n,n为至少一个SUL的数量。

在另一实施例中,还可以对配置在NUL和SUL上的CG资源,配置对应的优先选择参数,例如优先级高低(高或低),或者优先级等级(1、2、3、4等),和/或,选择因子。例如通过网络侧的指示信息配置。其中,选择因子可以用于确定优先级。
在一实施例中,可以通过高层信令向终端设备配置载波或资源的信息。
在其他实施例中,NUL和SUL的资源,以及资源对应的优先选择参数,还可以是预先定义的。
第一信息可以是终端设备侧确定传输上行数据的载波时需要参考的信息,第一信息用于表示选择上行载波时使用的时间限制信息、载波信息、资源信息或业务信息中的至少一项,例如包括网络侧的指示信息、终端设备侧自身确定的信息、网络侧提前给终端设备配置的信息或预定义的信息等。

其中,上述载波为NUL或SUL的载波,资源为NUL或SUL的资源。
其中,切换时间可以是网络配置的,也可以是预定义的,也可以是终端设备自身确定的。
该终端设备与其他终端设备的切换时间可以相同,也可以不同,其他终端设备之间的切换时间可以相同或不同。
在一实施例中,不同类型的终端设备的切换时间可以不同,同一类型的终端设备的切换时间可以相同。
切换时间包括射频RF链路的切换时间,或进一步还可以包括准备资源的时间或其他时间等。
终端设备从所述NUL的上行载波切换到SUL的上行载波、从一个SUL的上行载波切换到另一个SUL的上行载波或从SUL的上行载波切换到NUL的上行载波的切换时间相同或不同。

步骤102、终端设备利用第一上行载波发送上行数据。
若第一上行载波与当前使用的第二上行载波不同,终端设备可以从第二上行载波切换到第一上行载波,并利用第一上行载波发送上行数据;
若第一上行载波与第二上行载波相同,则终端设备维持在第二上行载波传输上行数据。
即终端设备维持在当前使用的第二上行载波上传输上行数据,此时第一上行载波为第二上行载波,即仍使用原第二上行载波传输上行数据。
在一实施例中,终端设备根据第二信息,确定当前使用的第二上行载波;第二信息包括以下至少一项:NUL和/或SUL中资源的优先选择参数、所述NUL和/或所述SUL的载波的优先选择参数、参考信号接收功率(Reference Signal Received Power,简称RSRP)、参考信号接收质量(Reference Signal Received Quality,简称RSRQ)、或网络设备发送的第二指示信息;第二指示信息用于指示初始载波信息,或者指示第一上行载波的信息。其中,第二指示信息还可以包括以下至少一项:载波标识,载波使用有效时间。
其中,初始载波可以是终端设备初始发送上行数据采用的载波,初始载波可以是第二上行载波或NUL或SUL的其他载波。即第二指示信息也可以指示当前要使用的载波的信息。
在一实施例中,还可以包括:
接收第四指示信息,第四指示信息用于配置终端设备是否能够切换载波。
具体的,网络侧可以向终端设备配置终端设备是否能够自主选择载波进行切换,即终端选择或切换载波的特性是可配置的。
本实施例的方法,在多个SUL的情况下可以增加上行容量,即对于多个终端设备来说,总体上可选择的UL增多。终端设备可以灵活切换UL的载波,可以灵活确定上行传输的载波或资源,给与了终端上行传输的灵活性,提高了资源传输效率,一定程度上缓解了PUSCH资源容量受限的问题。
假设终端设备当前使用的上行传输的载波为第二上行载波,则针对第一信息的不同内容,如何确定第一上行载波,可以通过如下几种方式:
方式1:
若第一信息包括网络侧指示的第一待切换载波的信息或所述网络侧指示的第一待切换载波对应的资源信息,即终端设备接收到网络设备的指示信息,该指示信息包括以下至少之一:第一切换标识,第一待切换载波的标识,第一待切换载波的资源,如动态资源;步骤101具体可以通过如下方式实现:
终端设备将第一待切换载波作为第一上行载波。
具体的,终端设备可以根据网络设备的指示选择上行传输的载波,将第一待切换载波作为第一上行载波,若第一待切换载波与当前使用的第二上行载波不同,则进行载波切换,将第二上行载波切换为第一上行载波。
例如,若当前使用的第二上行载波为一个SUL的载波,第一待切换载波可以是NUL或其他SUL的载波,或当前使用的第二上行载波为NUL的载波,第一待切换载波可以是SUL的载波。
方式2:
若第一信息包括:切换时间;即从当前使用的第二上行载波切换到NUL或SUL的其他载波需要的切换时间,即NUL或SUL的载波中除第二上行载波的其他载波;则可以采用如下几种方式实现:
方式2-1:
步骤101之前,还包括:
终端设备接收第一指示信息,第一指示信息包括:第二待切换载波的资源的起始时间;第一指示信息还可以包括以下至少之一:第二切换标识,第二待切换载波的标识,其中,第一指示信息可以是DCI信息;
步骤101,具体包括:
终端设备根据第一指示信息包括的第二待切换载波的资源的起始时间,以及第一信息包括的切换时间,确定是否将第二待切换载波作为第一上行载波。
即在该方式2-1中需要通过网络设备指示的载波的信息,确定是否切换载波。
例如,若当前使用的第二上行载波为一个SUL的载波,第二待切换载波可以是NUL的载波或其他SUL的载波,或当前使用的第二上行载波为NUL的载波,第二待切换载波可以是SUL的载波。
其中,终端设备根据第二待切换载波的资源的起始时间,以及切换时间,确定是否将第二待切换载波作为第一上行载波可以通过如下方式实现:
若第二待切换载波的资源的起始时间和第二上行载波的资源的起始时间的时间差,大于切换时间,则终端设备将第二待切换的载波作为第一上行载波;
或,
若第一指示信息的接收时间或解出时间到第二待切换载波的资源的起始时间的时间差,大于切换时间,则终端设备将第二待切换载波作为第一上行载波。
示例性的,当终端设备当前使用的第二上行载波为NUL的载波时,如使用NUL的CG资源(或DG资源)传输数据时,若此时收到网络设备的指示在其他SUL进行上行传输时,若NUL的CG资源和SUL的CG资源或DG资源的起始时间的时间差大于切换时间,则终端设备切换到SUL使用CG资源或DG资源传输上行数据,否则终端设备仍维持在NUL传输。
示例性的,当终端设备当前使用的第二上行载波为NUL的载波时,如NUL上配置有激活的CG资源(或DG资源),若此时收到网络设备的指示在其他SUL的上行传输时,若第一指示信息的接收或解出的时间到SUL的资源的起始时间的时间差大于切换时间,则终端切换到SUL使用CG资源或DG资源传输上行数据,否则终端设备仍维持在NUL传输。在其他实施例中,若终端设备当前使用的第二上行载波为一个SUL的载波时,若此时收到网络设备的指示在NUL或其他SUL进行上行传输时,与上述情况类似。
进一步的,在确定可以从第二上行载波切换到第一上行载波后,终端设备可以最晚在N-K时刻从第二上行载波切换到第一上行载波;
或者,步骤102,包括:
终端设备最晚在N-K时刻利用第一上行载波发送上行数据;
其中,N为第一上行载波的资源的起始时间,K为切换时间。
示例性的,终端设备当前使用的第二上行载波为NUL的载波时,如NUL上配置有激活的CG资源,若此时收到指示信息在其他SUL的上行传输时,终端设备可以先使用NUL的CG资源继续传输上行数据,最晚在N-K时刻从NUL切换到SUL,或最晚在N-K时刻利用SUL的资源传输上行数据。SUL的资源可以是CG资源或DG资源。或,NUL当前的资源也可以是DG资源。
方式2-2:
若NUL的配置的授权CG资源的起始时间和SUL的CG资源的起始时间的时间差,大于或等于切换时间,且第二上行载波为NUL的载波,则终端设备将SUL的载波作为第一上行载波;
若NUL的CG资源的起始时间和SUL的CG资源的起始时间的时间差,大于或等于切换时间,且第二上行载波为SUL的载波,则终端设备将NUL的载波作为第一上行载波。
该方式2-2可以不需要网络侧的指示,终端设备自主确定第一上行载波。
示例性的,NUL和SUL均有配置并激活的CG资源。当终端设备当前使用的第二上行载波为NUL的载波,并使用CG资源传输上行数据时,若SUL上的CG资源和NUL的CG资源的时间差大于切换时间,则终端设备切换到SUL使用CG资源传输,否则终端设备仍维持在NUL传输上行数据。
示例性的,NUL和SUL均有配置并激活的CG资源。当终端设备当前使用的第二上行载波为SUL的载波,并使用CG资源传输上行数据时,若SUL上的CG资源和NUL的CG资源的时间差大于切换时间,则终端设备切换到NUL使用CG资源传输,否则终端设备仍维持在SUL传输上行数据。
该方式2中在切换时进一步还可以考虑其他信息,例如载波的优先选择参数、资源的优先选择参数、业务优先级、预设时长、载波或资源的状态等。
方式3:
若第一信息包括:预设时长,则终端设备根据第一信息,确定待传输的上行数据使用的第一上行载 波,包括:
若终端设备确定当前时间和上次的载波切换时间的时间间隔小于预设时长,则终端设备将当前使用的第二上行载波作为第一上行载波。
具体的,记录终端设备执行载波切换的时间,若当前时间和上一次的载波切换时间的间隔小于预设时长,则不进行载波切换,即维持当前的第二上行载波传输上行数据;
若间隔大于或等于预设时长,则可以进行载波切换。
在一实施例中,预设时长指的是在终端设备执行载波切换后,不能进行载波切换或主动的载波切换的时长。其中,主动的载波切换情况下,若接收到网络设备的指示则可以切换,不受预设时长限制。
其中,该预设时长可以是配置的,预定义的,终端设备自身确定的。
在一实施例中,可以通过定时器的形式实现对载波切换的时间间隔的控制。如在切换后,或收到网络侧的切换指示后,开启定时器。定时器超时后,可以切换载波。进一步的,在定时器运行期间,若收到网络侧的载波切换指示,则切换载波,否则不换。
该方式3中在切换时进一步还可以考虑其他信息,例如切换时间、载波的优先选择参数、资源的优先选择参数、业务优先级、载波或资源的状态等。
方式4:
若第一信息包括:资源的优先选择参数,优先选择参数包括优先级和/或选择因子,则步骤101,具体可以通过如下方式实现:
若NUL和SUL中存在至少一个第三上行载波的资源的优先选择参数,高于第二上行载波的资源的优先选择参数,则终端设备从至少一个第三上行载波中选择第一上行载波。
若一个UL的载波上的资源为高优先选择参数的资源时,终端设备优先选择该资源进行上行传输。
示例性的,若NUL和SUL均有配置且激活的CG资源,且NUL的CG资源的优先级高。不论何种情况,如NUL和SUL的CG资源冲突(例如当前使用CG资源传输,但收到网络指示使用DG资源传输,或不满足载波优先级等情况下),或者终端设备当前使用的第二上行载波为SUL的载波,或者SUL和NUL的CG资源的起始时间之间的时间差小于切换时间,终端设备优先选择NUL的CG资源传输上行数据。
进一步的,若低优先级的资源正在传输,则终端设备可以直接切换到高优先级的资源上传输上行数据,不用等低优先级的资源传输完成。
该方式4中,同样适用于CG资源和DG资源,或DG资源和DG资源之间的切换,其中,SUL的资源为CG资源,NUL的资源为DG资源;或,NUL和SUL的资源均为DG资源;或,NUL的资源为CG资源,SUL的资源为DG资源;或,NUL和SUL的资源均为CG资源。
在一实施例中,该方式4具体可以通过如下几种方式选择第一上行载波:
若第二上行载波属于SUL,NUL的资源的优先选择参数,高于SUL的资源的优先选择参数,则至少一个第三上行载波为NUL的载波;或,
若第二上行载波属于SUL,SUL中除了第二上行载波的其他SUL的资源的优先选择参数,高于第二上行载波的资源的优先选择参数,则至少一个第三上行载波为其他SUL的载波;或,
若第二上行载波属于NUL,SUL的资源的优先选择参数,高于NUL的资源的优先选择参数,则至少一个第三上行载波为SUL的载波;或
终端设备从至少一个第三上行载波中选择第一上行载波,包括:
若至少一个第三上行载波包括NUL的载波,则从至少一个第三上行载波选择NUL的载波作为第一上行载波;或,
将至少一个第三上行载波中载波标识最小的载波作为第一上行载波;或,
将至少一个第三上行载波中特定的载波标识的载波作为第一上行载波。
具体的,若NUL的资源的优先选择参数,高于SUL的资源的优先选择参数,则可以选择优先选择参数高于第二上行载波的NUL的载波为第一上行载波;
若SUL中除了第二上行载波的其他SUL的载波的资源的优先选择参数,高于第二上行载波的资源的优先选择参数,则可以其他SUL的载波中选择第一上行载波。
若第二上行载波属于NUL,SUL的资源的优先选择参数,高于NUL的资源的优先选择参数,则可以从SUL的载波中选择第一上行载波。
若至少一个第三上行载波包括NUL的载波,则可以优先选择NUL的载波作为第一上行载波;或,将至少一个第三上行载波中载波标识最小的载波作为第一上行载波;或,将至少一个第三上行载波中特定的载波标识的载波作为第一上行载波。
该方式4中在切换时进一步还可以考虑其他信息,例如切换时间、载波的优先选择参数、业务优先级、载波或资源的状态等。
其中,至少一个第三上行载波的资源为动态的授权DG资源,第二上行载波的资源为CG资源。
即可以预先定义或配置,DG资源的优先选择参数高于CG资源的优先选择参数。
不论何种情况,如不同UL的载波的资源冲突,或者终端设备当前使用的第二上行载波不是传输DG资源的载波,或者非当前使用的载波的DG资源的起始时间和当前使用的第二上行载波的CG资源的起始时间之间的时间差小于切换时间,终端设备优先选择DG资源传输上行数据。
方式5:
若第一信息包括:载波的状态;则步骤101具体可以通过如下方式实现:
若NUL和SUL中存在至少一个第四上行载波的状态为激活状态,则终端设备从至少一个第四上行载波中选择第一上行载波。
若第一信息包括:资源的状态;则步骤101具体可以通过如下方式实现:
若NUL和SUL中存在至少一个第一资源的状态为激活状态,则终端设备从至少一个第一资源对应的上行载波中选择第一上行载波。
在该方式5中激活状态的载波或载波上的资源为可选择的用于上行传输的载波或资源。
其中,至少一个第四上行载波的资源为CG资源,或至少一个第一资源为CG资源,即仅配置并激活的CG资源才是可选择的用于上行传输的资源。
该方式5中在切换时进一步还可以考虑其他信息,例如切换时间、资源的优先选择参数、载波的优先选择参数、业务优先级等。
方式6:
第一信息包括:载波的优先选择参数,优先选择参数包括优先级和/或选择因子,步骤101具体可以通过如下方式实现:
若NUL和SUL中存在至少一个第五上行载波的优先选择参数,高于第二上行载波的优先选择参数,则从至少一个第五上行载波中选择第一上行载波。
具体的,终端设备可以优先选择优先级或选择因子高的载波上的资源进行传输。
在一实施例中,具体可以通过如下几种方式确定第一上行载波:
若第二上行载波属于SUL,NUL的载波的优先选择参数高于SUL的载波的优先选择参数,则至少一个第五上行载波为NUL的载波;或,
若第二上行载波属于NUL,SUL的载波的优先选择参数高于NUL的载波的优先选择参数,则至少一个第五上行载波为SUL的载波;或,
若第二上行载波属于SUL,SUL中除了第二上行载波的其他SUL的载波的优先选择参数,高于第二上行载波的优先选择参数,则至少一个第五上行载波为其他SUL的载波。
示例性的,若NUL的载波优先级高,则不论何种情况,如NUL和SUL的资源冲突,或者终端当前使用的第二上行载波为SUL的载波,或者SUL和NUL的资源的起始时间之间的时间差小于切换时间,终端设备优先选择NUL载波的资源传输上行数据。
进一步的,若低优先级的载波的资源正在传输上行数据,则终端设备可以直接切换到高优先级的载波的资源上传输上行数据,不用等低优先级的载波的资源传输完成。
该方式6中,同样适用于CG资源和DG资源,或DG资源和DG资源之间的切换,其中,SUL的资源为CG资源,NUL的资源为DG资源;或,NUL和SUL的资源均为DG资源;或,NUL的资源为CG资源,SUL的资源为DG资源;或,NUL和SUL的资源均为CG资源。
该方式6中在切换时进一步还可以考虑其他信息,例如切换时间、资源的优先选择参数、业务优先级、载波或资源的状态等。
方式7:
第一信息包括:业务优先级,步骤101具体可以通过如下方式实现:
若NUL和SUL中存在至少一个第六上行载波或至少一个第二资源上待传输的上行数据的业务优先级,高于第二上行载波上传输的上行数据的业务优先级,则从至少一个第六上行载波或至少一个第二资源对应的上行载波中选择第一上行载波。
其中,业务优先级可以通过业务的高/低优先级或高/低QoS表示。
具体的,若一个UL的载波(或资源)上的待传输上行数据的业务为高优先级的业务时,终端设备优先选择该业务的上行数据进行传输。
在一实施例中,具体可以通过如下几种方式确定第一上行载波:
若第二上行载波属于SUL,NUL的载波对应的业务优先级,高于SUL的载波对应的业务优先级,则至少一个第六上行载波为NUL的载波;或,
若第二上行载波属于SUL,SUL中除了第二上行载波的其他SUL的载波对应的业务优先级,高于第二上行载波对应的业务优先级,则至少一个第六上行载波为其他SUL的载波;或,
若第二上行载波属于NUL,SUL的载波对应的业务优先级,高于NUL的载波对应的业务优先级,则至少一个第六上行载波为SUL的载波;或,
若第二上行载波属于SUL,NUL中资源对应的业务优先级,高于SUL中资源对应的业务优先级,则至少一个第二资源为NUL中的资源;或,
若第二上行载波属于SUL,SUL中除了第二上行载波的资源的其他资源对应的业务优先级,高于第二上行载波的资源对应的业务优先级,则至少一个第二资源为SUL中除了第二上行载波的资源的其他资源;或,
若第二上行载波属于NUL,SUL中资源对应的业务优先级,高于NUL中资源对应的业务优先级,则至少一个第二资源为SUL中的资源。
其中,假设SUL为至少两个,至少两个SUL中除了第二上行载波对应的SUL之外的其他SUL的载波对应的业务优先级,高于第二上行载波对应的业务优先级,则至少一个第六上行载波为其他SUL的载波。
示例性的,若NUL和SUL均有配置且激活的CG资源,且NUL的CG资源对应的业务优先级高。不论何种情况,如NUL和SUL的CG资源冲突,或者终端设备当前使用的第二上行载波为SUL的载波,或者SUL和NUL的CG资源的起始时间之间的时间差小于切换时间,终端设备优先选择NUL的CG资源传输上行数据。
进一步的,若低优先级的业务正在传输,则终端设备可以直接切换到高优先级的业务去传输,不用等低优先级的业务传输完成。
该方式7中,同样适用于CG资源和DG资源,或DG资源和DG资源之间的切换,其中,SUL的资源为CG资源,NUL的资源为DG资源;或,NUL和SUL的资源均为DG资源;或,NUL的资源为CG资源,SUL的资源为DG资源;或,NUL和SUL的资源均为CG资源。
该方式7中在切换时进一步还可以考虑其他信息,例如切换时间、资源的优先选择参数、载波的优先选择参数、载波或资源的状态等。
在一实施例中,如果NUL和SUL都配置了CG资源,如果当前NUL或SUL其一有CG资源传输某一业务的上行数据,如果另一业务根据其逻辑信道优先级和CG资源的映射关系需要启用另一个UL上的CG资源传输时,终端设备对比新业务与当前CG资源上业务的优先级,决定是否停止当前CG资源传输上行数据,切换到新的UL载波的CG资源上传输新业务的上行数据。例如新业务优先级高或者优先传输,则终端设备切换到新的UL上传输高优先级的业务(即使当前CG资源上还没有传完数据)。例如新业务优先级低或者低优先传输,则终端设备不切换到新的UL上传输(优先保证当前业务传输)
如图3所示,假设当前通过NUL载波上的CG1资源(例如为type1CG资源)传输业务1的上行数据,然后接收到网络设备的指示信息(例如通过DCI指示),指示传输业务2的上行数据,SUL的载波的DG资源用于传输高优先级的业务的上行数据,则切换到图中SUL的载波的DG资源传输业务2的上行数据,由于图3中第3个CG1资源与SUL的载波的DG资源之间的时间差小于切换时间,因此图3中第3个CG1资源不可用,不能继续传输业务1的上行数据。
图3中,第4个CG1资源与SUL的载波的DG资源之间的时间差大于切换时间,当前又没有接收到网络设备的指示,因此可以切换回NUL的载波的CG1资源上传输业务1的数据。
如图4所示,假设NUL和SUL的载波均配置了CG资源(NUL配置了CG1资源,SUL配置了CG2资源,type2CG资源),当前通过NUL载波上的CG资源传输业务1的上行数据,则图4中,SUL的载波上第1个CG2资源不可用,然后接收到网络设备的指示信息(例如通过DCI指示),指示传输业务2的上行数据,SUL的载波的CG2资源用于传输高优先级的业务的上行数据,则切换到图4中SUL的载波的CG2资源传输业务2的上行数据,由于图4中NUL上第3个CG1资源与SUL的载波的CG2资源之间的时间差小于切换时间,因此图4中第3个CG1资源不可用,不能继续传输业务1的上行数据。
图4中,NUL上第4个CG1资源与SUL的载波的CG2资源(SUL上第3个CG2资源)之间的时间差小于切换时间,因此NUL上第4个CG1资源不可用。终端设备继续在SUL上第3个CG2资源传输业务2的上行数据。
方式8:
第一信息包括:用于切换的载波标识信息,步骤101具体可以通过如下方式实现:
若载波标识信息指示NUL的载波,则从NUL和SUL中选择NUL的载波作为第一上行载波;或,
若载波标识信息指示载波标识最小的载波,将NUL和SUL中载波标识最小的载波作为第一上行载波;或,
若载波标识信息指示特定的载波标识的载波,将NUL和SUL中特定的载波标识的载波作为第一上行载波。
其中,若选择NUL的载波作为第一上行载波,进一步还可以考虑其他信息,例如切换时间、资源的优先选择参数、载波的优先选择参数、载波或资源的状态等。
在一实施例中,还可以包括:
接收第五指示信息,第五指示信息包括载波标识信息。第五指示信息用于指示待选择的第一上行载波为NUL的载波,或,用于指示第一上行载波为载波标识最小的载波,或用于指示第一上行载波为特定的载波标识的载波。
本申请实施例的方法,终端设备可以灵活切换UL的载波,可以灵活确定上行传输的载波或资源,给与了终端上行传输的灵活性,提高了资源传输效率,一定程度上缓解了PUSCH资源容量受限的问题。
在本申请的另一实施例中,若终端设备利用第一上行载波的DG资源传输上行数据完成,则终端设备从第一上行载波切换到第二上行载波;或,
若终端设备利用第一上行载波的有效资源传输上行数据完成,终端设备从第一上行载波切换到第二上行载波,有效资源包括有效的DG资源和/或CG资源;或,
若终端设备接收到第三指示信息,终端设备从第一上行载波切换到第二上行载波,第三指示信息包括第二上行载波的信息。
具体的,终端设备根据配置的CG资源和/或调度的DG资源、或网络侧的指示等,确定是否切换UL的载波,或者,维持在当前UL的上行载波进行数据传输。若执行了载波切换,原第二上行载波有配置且激活的CG资源,则终端设备可以执行以下操作之一:
在第一上行载波的DG资源(一个DG资源或重复的DG资源)传输完成后,终端设备主动切换回第二上行载波。
在第一上行载波的有效UL资源传输完成后(DG资源和/或CG资源),终端设备主动切换回第二上行载波。此外,也可以通过网络配置或指示的方式,确定有效UL资源,如网络指示有效UL资源的资源标识/资源标识列表。
仅在网络侧指示在第二上行载波传输后(例如通过DCI指示第二上行载波的标识或该第二上行载波上资源的标识),终端设备重选切换回第二上行载波。网络侧可以指示资源的信息。
该实施例的方法,适用于任意两个载波之间的切换。
本实施例中,给了一种更简单的切换规则,即终端设备仅在收到网络侧指示切换UL上行载波时,或者,在当前的上行载波没有有效资源时(DG和/或CG),终端设备可以切换UL上行载波。其好处在于降低了终端设备处理的复杂度。
如图5所示,假设当前通过NUL载波上的CG资源传输业务1的上行数据,然后接收到网络设备的指示信息,指示传输业务2的上行数据,业务2的优先级高于业务1的优先级,SUL的载波的DG资源用于传输高优先级的业务的上行数据,则切换到图5中SUL的载波的DG资源传输业务2的上行数据,由于图5中SUL的载波的DG资源传输业务2的上行数据没有完成,因此图中NUL上第2、3个CG资源不可用,不能继续传输业务1的上行数据。
图5中,接收到网络设备的调度指示,指示在NUL上传输业务3的上行数据,则切换到NUL上DG资源,传输完成后(即有效资源用完后)切换回NUL上第4个CG资源传输业务1的上行数据。
在本申请的另一实施例中,第二上行载波上的CG资源配置为:若终端设备从第二上行载波切换到第一上行载波后,第二上行载波上的CG资源不使用或挂起;若终端设备从第一上行载波切换到第二上行载波后,第二上行载波上的CG资源可用或恢复;或,
若终端设备从第二上行载波切换到第一上行载波后,第二上行载波上的CG资源去激活或去配置;若终端设备从第一上行载波切换到第二上行载波后,第二上行载波上的CG激活或重配。
具体的,终端设备在确定切换UL载波时,或确定UL载波后,可以将原上行载波配置为:
在原第二上行载波上的CG资源暂时不使用或挂起(suspend),直至传输上行数据的上行载波重新切换到原第二上行载波,再开始使用有效CG资源或有效资源恢复(有效CG资源指的是切换回原第二上行载波之后的配置且激活的CG资源)。
在原第二上行载波上CG资源去激活或去配置。当终端设备切换回原第二上行载波后,网络设备重 新配置或激活该CG资源。
本实施例中给出了切换后原上行载波的资源的使用规则。由于终端设备UL载波切换导致不能使用的UL资源,网络可以给其他终端设备调度使用,保证了系统资源的有效利用,避免了系统资源的浪费。
如图6所示,假设当前通过NUL载波上的CG资源传输业务1的上行数据,然后接收到网络设备的指示信息,指示传输业务2的上行数据,业务2的优先级高于业务1的优先级,SUL的载波的DG资源用于传输高优先级的业务的上行数据,则切换到图6中SUL的载波的DG资源传输业务2的上行数据,NUL上第2、3、4个CG资源配置为暂时不使用、去激活、挂起或去配置,不能继续传输业务1的上行数据。
图6中,接收到网络设备的调度指示,指示在NUL上传输业务3的上行数据,则切换到NUL上DG资源传输业务3的上行数据。
