Description

支持sTTI的基站、用户设备及其执行的方法 技术领域
本发明涉及无线通信技术领域,更具体地,本发明涉及短时传输时间间隔(Short Transmission Time Interval,sTTI)下的功率控制方法,以及基站和用户设备。
背景技术
现代无线移动通信系统呈现出两个显著特点,一是宽带高速率,比如第四代无线移动通信系统的带宽可达100MHz,下行速率高达1Gbps;二是移动互联,推动了移动上网、手机视频点播、在线导航等新兴业务。这两个特点对无线移动通信技术提出了较高要求,主要有:超高速率无线传输、区域间干扰抑制、移动中可靠传输信号、分布式/集中式信号处理等等。在未来的增强第四代(4G)及第五代(5G)无线移动通信系统中,为了满足上述发展需求,各种相应的关键技术开始被提出和论证,值得本领域的研究人员广泛关注。
在2016年6月举行的3GPP RAN 72全会上,提出了一个新的工作项目(参见非专利文献:RP-161044:New WID for LTE:Latency reduction by processing time reduction)。在该项目的前期研究(study item,SI)中,延迟降低(Latency Reduction)技术将在上行和下行同时支持短时TTI(short TTI,简称sTTI),其中1个sTTI包含的正交频分复用(OFDM)符号的数目小于14,例如其可以包含2个OFDM符号或7个OFDM符号,或者包含其他小于14的数目的OFDM符号。该项目支持的下行信道有短时物理下行控制信道(Short Physical Downlink Control Channel,简称sPDCCH)和短时物理下行共享信道(Short Physical Downlink Shared Channel,简称sPDSCH)。该项目支持的上行信道有短时物理上行控制信道(Short Physical Uplink Control Channel,简称sPUCCH)和短时物理上行共享信道(Short Physical Uplink Shared Channel,简称sPUSCH)。其中sPDCCH,sPDSCH,sPUCCH以及sPUSCH都是以sTTI作为传输 时间间隔的物理信道。sPDCCH用于传输下行控制信息,sPDSCH用于传输下行数据信息,sPUCCH用于传输上行控制信息,sPUSCH用于传输上行数据信息。
同时,很多公司提出希望UE同时支持延迟降低的sTTI和LTE/LTE-A的TTI,其中LTE/LTE-A的TTI时间长度为1ms,包含有14个OFDM符号。本发明中,TTI指的是LTE/LTE-A的持续周期为1ms且包含14个OFDM符号的子帧(subframe)或者传输时间间隔;sTTI指的是持续周期小于1ms且包含小于14个OFDM符号的子帧(subframe)或者传输时间间隔,例如其可以包含2个OFDM符号或7个OFDM符号,或者包含其他小于14的数目的OFDM符号。

在附图中,相同的附图标记指示相同或类似的要素。
具体实施方式
下面结合附图和具体实施方式对本发明进行详细阐述。应当注意,本发明不应局限于下文所述的具体实施方式。另外,为了简便起见,省略了对与本发明没有直接关联的公知技术的详细描述,以防止对本发明的理解造成混淆。
下文以LTE移动通信系统及其后续的演进版本作为示例应用环境,具体描述了根据本发明的多个实施方式。然而,需要指出的是,本发明不限于以下实施方式,而是可适用于更多其它的无线通信系统,例如今后的5G蜂窝通信系统。
本发明中,TTI(Transmission Time Interval)指的是LTE/LTE-A的持续周期为1ms且包含14个OFDM符号的子帧(subframe)或者传输时间间隔;sTTI指的是持续周期小于1ms且包含小于14个OFDM符号的子帧(subframe)或者传输时间间隔,例如其可以包含2个OFDM符号或7个OFDM符号,或者包含其他小于14的数目的OFDM符号。为了便于区分,也将TTI称为LTE TTI,将sTTI称为短时TTI。
本发明中,探测参考信号(Sounding Reference Signal,简称SRS)是LTE支持的用于信道探测的参考信号,其以TTI为传输时间间隔进行传输。通过UE发送SRS,可以帮助基站测量信道质量。另外,SRS还可以用于控制上行链路功率或上行链路定时提前。
本发明中,物理上行共享信道(PUSCH)和物理上行控制信道(PUCCH)是LTE支持的以TTI作为传输时间间隔的物理信道。短时物理上行共享信道(sPUSCH)和短时物理上行控制信道(sPUCCH)是前述延迟降低(Latency Reduction)技术支持的以sTTI作为传输时间间隔的物理信道。其中,PUCCH和sPUCCH均用于传输上行控制信息,PUSCH和sPUSCH均用于传输上行数据信息。
与传统的LTE系统中的情形类似,在本发明实施例的系统中,基站向用户设备提供无线电接入。基站可以包括调度器,用于在所服务的UE之间分配上行链路(UL)数据传输资源和下行链路(DL)数据传输资源。调度器将决定针对每一个UE的分组数据传输要使用的资源(例如,时频资源),以及监控分组分配和系统负载。
在本发明实施例中将主要考虑上行传输及其资源配置。具体地,本发明实施例中,由于UE同时支持TTI和sTTI,基站的调度器将配置用 于SRS传输、PUSCH传输、PUCCH传输、sPUSCH传输、sPUCCH传输等的物理层资源,并且通过控制信道向UE发送这些配置信息。UE参考从基站接收的配置信息来确定用于上行链路传输(如SRS传输、PUSCH传输、PUCCH传输、sPUSCH传输、sPUCCH传输等)的时序、频率、调制和编码等。
基站给UE配置的基于TTI的传输(如SRS传输、PUSCH传输、和/或PUCCH传输)和基于sTTI的传输(如sPUSCH传输、和/或sPUCCH传输)有可能并发并因此发生冲突,此时需要一种合适的方式来解决这种情况。本发明实施例提供了解决这种并发冲突的方案。下面参考附图进行详细描述。
图1示出了根据本发明实施例的支持TTI和sTTI二者的基站BS 100的框图。应该理解,所述基站BS 100可以是新的独立设备,或者通过改进现有LTE基站来实现。如图所示,基站BS 100可以包括:发射单元110、调度器120和接收单元130。
基站的调度器120配置为:生成针对所服务的用户设备UE的上行资源配置信息。例如,生成针对UE的SRS传输、PUSCH传输、PUCCH传输、sPUSCH传输、sPUCCH传输等的物理资源配置信息。
基站通过发射单元110向UE发送下行传输。例如通过发射单元110,经由控制信道向UE发送调度器生成的针对UE的配置信息。
接收单元130配置为接收UE发送的上行传输。
本领域技术人员应理解,基站BS 100还可以包括实现其功能所必需的其他功能单元,如各种存储器、基带信号生成/提取单元、其他物理上行信道接收处理单元和其它物理下行信道发射处理单元等等。然而为了简便,省略了这些公知元件的详细描述。
图2示出了根据本发明的支持TTI和sTTI二者的用户设备UE 200的框图。应该理解,所述UE 200可以是新的独立设备,或者通过改进现有LTE的用户设备来实现。如图所示,UE 200可以包括:接收单元210、发射单元220、以及处理单元230。接收单元210配置为接收来自基站的下行传输,例如来自基站的针对SRS传输、PUSCH传输、PUCCH传输、sPUSCH传输、sPUCCH传输等的资源配置信息。处理单元230配置为根据所接收的来自基站的配置信息,确定用于SRS传输、PUSCH 传输、PUCCH传输、sPUSCH传输、sPUCCH传输等的资源配置,如时序、频率、调制和编码等。特别地,根据本发明实施例,UE的处理单元230将确定当存在并发的基于sTTI的传输与基于TTI的传输时,如何避免冲突。发射单元220配置为向基站发送上行传输,例如根据处理单元230确定的资源配置来发射SRS传输、PUSCH传输、PUCCH传输、sPUSCH传输、sPUCCH传输等。
本领域技术人员应理解,UE 200还包括实现其功能所必需的其他功能单元,如各种存储器、基带信号生成/提取单元、其他物理下行信道接收处理单元和其他物理上行信道发射处理单元等等。然而为了简便,省略了这些公知元件的详细描述。
在本发明实施例中,SRS传输,PUCCH和PDCCH是基于TTI的传输的示例。sPDCCH和sPUCCH是基于sTTI的传输的示例。
本发明实施例提出,当要进行的基于TTI的传输和基于sTTI的传输落在同一OFDM符号内,落在同一传输时间间隔TTI内,或者落在同一短时传输时间间隔sTTI内,认为基于TTI的传输和基于sTTI的传输出现了并发情形。。
在并发情形下,本发明提出可以采取下述抑制策略之一以避免冲突:在发生重叠的OFDM符号内,只执行基于TTI的传输和基于sTTI的传输中的一个,而抑制另一个;备选地,在发生重叠的传输时间间隔TTI内,只执行基于TTI的传输和基于sTTI的传输中的一个,而抑制另一个;备选地,在发生重叠的短时传输时间间隔sTTI内,只执行基于TTI的传输和基于sTTI的传输中的一个,而抑制另一个;备选地,在发生重叠的时频资源上只执行基于TTI的传输和基于sTTI的传输中的一个,而打孔(puncture)掉另一个,其中所述时频资源是一个或多个RE(资源单元)或者一个或多个RB(资源块)。
在本发明的一些实施例中,可以预先设定UE在并发期中只执行基于TTI的传输而抑制基于sTTI的传输;或者反之,只执行基于sTTI的传输而抑制基于TTI的传输。
根据本发明的另一些实施例,基站还可以向UE发送另一配置信息,以指示是否允许基于TTI的传输和基于sTTI的传输并发执行。仅在该另一配置信息指示不允许基于TTI的传输和基于sTTI的传输并发执行时, 才在所调度的基于TTI的传输和基于sTTI的传输的并发期中,抑制基于TTI的传输,或者抑制基于sTTI的传输。
优选地,本发明还提出,仅在UE没有配置载波聚合时,才执行上述的在基于TTI的传输和基于sTTI的传输存在并发时抑制二者之一的方案,而在UE配置了载波聚合时,不执行上述抑制方案。这是考虑到,在UE配置了载波聚合后,可以通过其他调度来避免TTI传输和sTTI传输的冲突,因此可能不需要使用上述抑制方案。本发明还提出,可以通过确定是否收到多个(多于一个)时间提前组(Timing Advance Group,简称TAG)的配置来判断是否配置了载波聚合。具体地,当收到多个TAG时,说明UE配置了载波聚合,反之则没有配置载波聚合。
下面参考图3-图6来详细描述当UE同时支持TTI和sTTI时,UE如何处理并发的基于TTI的传输和基于sTTI的传输。
下面参考图3来说明当出现并发的SRS传输和sPUSCH时的处理方案。图3示出了根据本发明实施例的基站BS 100配置用户设备UE 200进行SRS传输和sPUSCH传输的方法1000的流程图。
如图所示,该方法开始于步骤S1110步骤。
在步骤S1110中,基站100(具体地,通过调度器)生成针对UE 200的上行资源配置信息,所述配置信息指示UE要进行SRS传输和sPUSCH传输。
在步骤S1120中,基站100向UE 200发送所生成的配置信息。
在步骤S1210中,UE 200接收基站发送的配置信息。
在步骤S1220中,UE 200根据所接收的配置信息向基站100发送上行传输。其中,当根据配置信息确定要进行的SRS传输和sPUSCH传输存在并发时,或者备选地当根据所接收的配置信息确定要进行的SRS传输和sPUSCH传输存在并发并且没有收到多于一个时间提前组时:UE在并发期中只执行SRS传输和sPUSCH传输之一而抑制另一个。
在步骤S1130中,基站100接收UE 200发送的上行传输。
步骤S1220中UE执行的抑制策略可以用多种方式实现。为了便于理解,下面列出若干示例。
作为一个实施例,基站发送配置信息指示UE进行SRS传输和sPUSCH传输。当SRS和sPUSCH在同一OFDM符号传输或在同一TTI 传输或在同一sTTI传输时,UE传输SRS,不传输sPUSCH。
作为另一个实施例,基站发送配置信息指示UE进行SRS传输和sPUSCH传输。当没有收到多个时间提前组(Timing Advance Group,TAG)的配置,且SRS传输和sPUSCH传输在同一OFDM符号传输或在同一TTI传输或在同一sTTI传输时,UE传输SRS,不传输sPUSCH。
作为另一个实施例,基站发送配置信息指示UE进行SRS传输和sPUSCH传输。当SRS传输和sPUSCH传输在同一OFDM符号传输或在同一TTI传输或在同一sTTI传输时,UE传输sPUSCH,不传输SRS。
作为另一个实施例,基站发送配置信息指示UE进行SRS传输和sPUSCH传输。当没有收到多个TAG的配置,且SRS传输和sPUSCH传输在同一OFDM符号传输或在同一TTI传输或在同一sTTI传输时,UE传输sPUSCH,不传输SRS。
作为另一个实施例,基站发送配置信息指示UE进行SRS传输和sPUSCH传输。当SRS传输和sPUSCH传输在同一OFDM符号传输或在同一TTI传输或在同一sTTI传输时,SRS与sPUSCH重叠的时频资源的处理方法是打孔(puncture)掉重叠区域的SRS,其中时频资源指的是若干个RE或者是若干个RB。
作为另一个实施例,基站发送配置信息指示UE进行SRS传输和sPUSCH传输。当SRS传输和sPUSCH传输在同一OFDM符号传输或在同一TTI传输或在同一sTTI传输时,SRS与sPUSCH重叠的时频资源的处理方法是打孔(puncture)掉重叠区域的sPUSCH,其中时频资源指的是若干个RE或者是若干个RB。
作为另一个实施例,基站发送配置信息指示UE进行SRS传输和sPUSCH传输。当SRS传输和sPUSCH传输在同一OFDM符号传输或在同一TTI传输或在同一sTTI传输时,SRS与sPUSCH重叠的时频资源的处理方法是对重叠区域的sPUSCH进行速率匹配(rate matching)。
下面参考图4来说明当出现并发的SRS传输和sPUCCH时的处理方案。图4示出了根据本发明实施例的基站BS 100配置用户设备UE 200进行SRS传输和sPUCCH传输的方法2000的流程图。
如图所示,该方法开始于步骤S2110步骤。
在步骤S2110中,基站100(具体地,通过调度器)生成针对UE 200 的上行资源配置信息,所述配置信息指示UE要进行SRS传输和sPUCCH传输。
在步骤S2120中,基站100向UE 200发送所生成的配置信息。
在步骤S2210中,UE 200接收基站发送的配置信息。
在步骤S2220中,UE 200根据所接收的配置信息向基站100发送上行传输。其中,当根据配置信息确定要进行的SRS传输和sPUCCH传输存在并发时,或者备选地当根据所接收的配置信息确定要进行的SRS传输和sPUCCH传输存在并发并且没有收到多于一个时间提前组时:UE在并发期中只执行SRS传输和sPUCCH传输之一而抑制另一个。
在步骤S2130中,基站100接收UE 200发送的上行传输。
步骤S2220中UE执行的抑制策略可以用多种方式实现。为了便于理解,下面列出若干示例。
作为一个实施例,基站发送配置信息指示UE进行SRS传输和sPUCCH传输。当SRS传输和sPUCCH传输在同一OFDM符号传输或在同一TTI传输或在同一sTTI传输时,UE传输SRS,不传输sPUCCH。
作为另一个实施例,基站发送配置信息指示UE进行SRS传输和sPUCCH。当没有收到多个TAG的配置,且SRS传输和sPUCCH传输在同一OFDM符号传输或在同一TTI传输或在同一sTTI传输时,UE传输SRS,不传输sPUCCH。
作为另一个实施例,基站发送配置信息指示UE进行SRS传输和sPUCCH传输。当SRS传输和sPUCCH传输在同一OFDM符号传输或在同一TTI传输或在同一sTTI传输时,UE传输sPUCCH,不传输SRS。
作为另一个实施例,基站发送配置信息指示UE进行SRS传输和sPUCCH传输。当没有收到多个TAG的配置,且SRS传输和sPUCCH传输在同一OFDM符号传输或在同一TTI传输或在同一sTTI传输时,UE传输sPUCCH,不传输SRS。
作为另一个实施例,基站发送配置信息指示UE进行SRS传输和sPUCCH传输。当SRS传输和sPUCCH传输在同一OFDM符号传输或在同一TTI传输或在同一sTTI传输时,SRS与sPUCCH重叠的时频资源的处理方法是打孔(puncture)掉重叠区域的SRS,其中时频资源指的是若干个RE或者是若干个RB。
作为另一个实施例,基站发送配置信息指示UE进行SRS传输和sPUCCH传输。当SRS传输和sPUCCH传输在同一OFDM符号传输或在同一TTI传输或在同一sTTI传输时,SRS与sPUCCH重叠的时频资源的处理方法是打孔(puncture)掉重叠区域的sPUCCH,其中时频资源指的是若干个RE或者是若干个RB。
作为另一个实施例,基站通过配置信令来指示是否允许UE同时进行SRS传输和sPUCCH传输。该配置信令可以由RRC来承载或者由物理层来承载。该配置信令可以具有二元值。例如将该配置信令记为sPUCCHSRS-SimultaneousTransmission。当sPUCCHSRS-SimultaneousTransmission配置为第一值(如True)时,SRS传输和sPUCCH可以在同一OFDM符号传输或在同一TTI传输或在同一sTTI传输。当sPUCCHSRS-SimultaneousTransmission配置为第二值(如False)时,SRS传输和sPUCCH不可以在同一OFDM符号传输或在同一TTI传输或在同一sTTI传输。具体地,当sPUCCHSRS-SimultaneousTransmission配置为第二值(如False)时,且当SRS传输和sPUCCH传输在同一OFDM符号传输或在同一TTI传输或在同一sTTI传输时,UE不传输SRS而是传输sPUCCH,如短类型的sPUCCH(shortened format sPUCCH),其中短类型的sPUCCH是包含OFDM数目小于其所在sTTI包含OFDM数目的sPUCCH。备选地,当sPUCCHSRS-SimultaneousTransmission配置为第二值(如False)时,且当SRS传输和sPUCCH传输在同一OFDM符号传输或在同一TTI传输或在同一sTTI传输时,UE传输SRS,不传输sPUCCH。
下面参考图5来说明当出现并发的SRS传输和sTTI传输时的处理方案。此处,sTTI传输包括sPUSCH传输和sPUCCH传输。图5示出了根据本发明实施例的基站BS 100配置用户设备UE 200进行SRS传输和sTTI传输的方法3000的流程图。
如图所示,该方法开始于步骤S3110步骤。
在步骤S3110中,基站100(具体地,通过调度器)生成针对UE 200的上行资源配置信息,所述配置信息指示UE要进行SRS传输和sTTI传输。
在步骤S3120中,基站100向UE 200发送所生成的配置信息。
在步骤S3210中,UE 200接收基站发送的配置信息。
在步骤S3220中,UE 200根据所接收的配置信息向基站100发送上行传输。其中,当根据配置信息确定要进行的SRS传输和sTTI传输存在并发时,或者备选地当根据所接收的配置信息确定要进行的SRS传输和sTTI传输存在并发并且没有收到多于一个时间提前组时:UE在并发期中只执行SRS传输和sTTI传输之一而抑制另一个。
在步骤S3130中,基站100接收UE 200发送的上行传输。
步骤S3220中UE执行的抑制策略可以用多种方式实现。为了便于理解,下面列出若干示例。
作为一个实施例,基站发送配置信息指示UE进行sTTI传输和SRS传输。当sTTI和SRS在同一OFDM符号传输或在同一TTI传输或在同一sTTI传输时,UE传输SRS,不传输sTTI。
作为另一个实施例,基站发送配置信息指示UE进行sTTI传输和SRS传输。当没有收到多个TAG的配置,且sTTI和SRS在同一OFDM符号传输或在同一TTI传输或在同一sTTI传输时,UE传输SRS,不传输sTTI。
作为另一个实施例,基站发送配置信息指示UE进行sTTI传输和SRS传输。当sTTI和SRS在同一OFDM符号传输或在同一TTI传输或在同一sTTI传输时,UE传输sTTI,不传输SRS。
作为另一个实施例,基站发送配置信息指示UE进行sTTI传输和SRS传输。当没有收到多个TAG的配置,且sTTI和SRS在同一OFDM符号传输或在同一TTI传输或在同一sTTI传输时,UE传输sTTI,不传输SRS。
作为另一个实施例,基站发送配置信息指示UE进行sTTI传输和SRS传输。当sTTI传输和SRS传输在同一OFDM符号传输或在同一TTI传输或在同一sTTI传输时,SRS与sTTI重叠的时频资源的处理方法是打孔(puncture)掉重叠区域的SRS,其中时频资源指的是若干个RE或者是若干个RB。
作为另一个实施例,基站发送配置信息指示UE进行sTTI传输和SRS传输。当sTTI传输和SRS传输在同一OFDM符号传输或在同一TTI传输或在同一sTTI传输时,SRS与sTTI重叠的时频资源的处理方法是打 孔(puncture)掉重叠区域的sTTI,其中时频资源指的是若干个RE或者是若干个RB。
作为另一个实施例,基站通过配置信令指示UE进行sTTI传输和SRS传输。该配置信令可以由RRC来承载或者由物理层来承载。该配置信令可以具有二元值。例如将该信令记为sTTISRS-SimultaneousTransmission。当sTTISRS-SimultaneousTransmission配置为第一值(如True)时,sTTI传输和SRS传输可以在同一OFDM符号传输或在同一TTI传输或在同一sTTI传输。当sTTISRS-SimultaneousTransmission配置为第二值(如False)时,sTTI传输和SRS传输不可以在同一OFDM符号传输或在同一TTI传输或在同一sTTI传输。
下面参考图6来说明当出现并发的TTI传输和sTTI传输时的处理方案。此处,TTI传输包括PUSCH传输和/或PUCCH传输。sTTI传输包括sPUSCH传输和/或sPUCCH传输。图6示出了根据本发明实施例的基站BS 100配置用户设备UE 200进行TTI传输与sTTI传输的方法4000的流程图。
如图所示,该方法开始于步骤S4110步骤。
在步骤S4110中,基站100(具体地,通过调度器)生成针对UE 200的上行资源配置信息,所述配置信息指示UE要进行TTI传输和sTTI传输,例如进行PUSCH传输和/或PUCCH传输与sPUSCH传输和/或sPUCCH传输。
在步骤S4120中,基站100向UE 200发送所生成的配置信息。
在步骤S4210中,UE 200接收基站发送的配置信息。
在步骤S4220中,UE 200根据所接收的配置信息向基站100发送上行传输。其中,当根据配置信息确定要进行的TTI传输和sTTI传输存在并发时,或者备选地当根据所接收的配置信息确定要进行的TTI传输和sTTI传输存在并发并且没有收到多于一个时间提前组时:UE在并发期中只执行TTI传输和sTTI传输之一而抑制另一个。
在步骤S4130中,基站100接收UE 200发送的上行传输。
步骤S4220中UE执行的抑制策略可以用多种方式实现。为了便于理解,下面列出若干示例。
作为一个实施例,当sPUSCH和PUSCH在同一OFDM符号传输或在同一TTI传输或在同一sTTI传输时,UE传输PUSCH,不传输sPUSCH。
作为另一个实施例,当sPUSCH和PUSCH在同一OFDM符号传输或在同一TTI传输或在同一sTTI传输时,UE传输sPUSCH,不传输PUSCH。
作为另一个实施例,当sPUCCH和PUSCH在同一OFDM符号传输或在同一TTI传输或在同一sTTI传输时,UE传输PUSCH,不传输sPUCCH。
