首先对本申请所涉及的应用场景进行介绍:
图2为本申请一实施例提供的网络架构示意图,本申请提供的技术方案基于如图1所示的网络架构,该网络架构中包括至少一个终端设备10,通过无线接口与网络设备20通信,为清楚起见,图2中只示出一个终端设备和一个网络设备。
5G新无线(New radio,NR)系统定义了三大应用场景,包括增强型移动宽带(enhanced mobile broadband,eMBB),超高可靠超低时延通信(ultra-reliable and low latency communication,URLLC)和海量机器类通信(massive machine type communications,mMTC)。目前研究人员发现实际的应用中还包括了一些不属于这三大应用场景的新业务和新的终端类型,它们有着一定的,但远小于eMBB的传输速率需求,它们对时延的要求比URLLC要低但可能又比eMBB要高,它们还有着机器类通信的业务属性。这种新业务(新场景)被定义为轻量级的新型无线技术(New radio-Light,NR-light)业务。
NR-Light主要考虑视频监控,工业传感器和可穿戴设备这几大应用场景。这类场景的终端,即NR-Light终端不需要很高的复杂度。其收/发天线数可能被降低至1根,其处理能力可能被降至MTC级别,其主要支持的制式将可能是半双工频分复用(HD-FDD)。在HD-FDD下,终端在某一时刻 只能收不能发,或者只能发不能收。这种制式下,终端在接收下行数据后需要对该数据进行反馈时,需要切换至上行再发送反馈信息。
如图3所示,HD-FDD模式下如果终端采用动态调度的方式,接收下行调度信息(DCI)后需切换至上行发送上行数据。
上述方式不利于上行数据的速率提升,对于视频监控的场景,DCI会占用比较多的子帧资源。
为了增加上行数据率,可以考虑采用动态多TB的调度方式,如图1所示,一个DCI一次性调度多个上行TB,该方式中,因为需要连续不断的为终端分配上行数据的资源,因此DCI的数量较多。虽然解决了上行传输速率的问题,但是DCI的开销仍然较大。
对于视频监控场景,其上行数据量通常远大于下行,且其数据有着一定的传输规律,如数量相对稳定、周期相对固定等。因此视频监控的场景可以使用配置授权(configured grant,CG)的方式进行数据传输。
配置授权CG指网络设备通过激活一次上行授权给终端设备,在终端设备不收到去激活的情况下,将会一直使用第一次上行授权所指定资源进行上行传输,其有两种传输类型:
配置授权type 1:由无线资源控制(Radio Resource Control,RRC)通过高层信令进行配置(IE ConfiguredGrantConfig);
配置授权type 2:由DCI进行指示上行授权的激活和去激活,其需要的参数由IE ConfiguredGrantConfig进行配置,但是需要由DCI激活时才进行使用。
本申请考虑在CG中引入多TB机制,即一个周期发多个TB,TB发送完成后转至下行接收可能的DCI信息。对此,终端只需确定一个周期传输的TB数,传完之后可以回到下行接收,在下一个周期再进行上行传输。相比于图1的技术,在CG中引入多TB不仅能解决了上行传输速率的问题,还能有效降低DCI的开销。
以下对配置授权进行详细介绍:
type 1配置授权和type 2配置授权根据IE ConfiguredGrantConfig中字段rrc-ConfiguredUplinkGrant进行区别。如果该字段rrc-ConfiguredUplinkGrant配置,则为type 1配置授权,如果该域未被配置,则为配置授权type 2,其IE ConfiguredGrantConfig详细配置如下所示:
Figure PCTCN2021085718-appb-000001
Figure PCTCN2021085718-appb-000002
rrc-ConfiguredUplinkGrant为type 1配置授权的特有参数,剩余部分参数为type1和type2的共有参数。从上面可以看出,如果上行授权配置类型为type 1,则rrc-ConfiguredUplinkGrant中的参数全为type 1需要的参数,其包括:时域资源、频域资源、调制编码方案(IMCS)、天线端口、SRS资源指示、解调参考信号(DM-RS)等相关参数。除此之外,IE ConfiguredGrantConfig也包含了type 1和type 2需要的公共参数,如:周期(periodicity)、HARQ进程数(nrofHARQ-Processes)、功控、重复次数(repK)、重复的冗余版本(repK-RV)等上行传输时需要的全部参数。
同时,对于type 2而言,可以看出,除了type 1和type 2需要的公共参数,其并没有配置时域资源、频域资源,调制编码方案(IMCS)等相关参数,从上文可知,配置授权type 2由DCI进行激活,因此对于type 2,当终端收到IE ConfiguredGrantConfig中配置的与type 1和type 2所需要的公共参数后,不会立即进行上行传输,只有当终端收到由CS-RNTI加扰的DCI指示激活,并会携带时域资源、频域资源,调制编码方案(IMCS)等相关参数,终端才会进行type 2的上行免授权传输。如果高层没有在上行免授权所分配的资源上传输DCI进行激活,则终端不会在GrantConfig配置的资源上发送任何内容。
本申请下面以具体的实施例对本申请的技术方案进行详细说明。下面这几个具体的实施例可以相互结合,对于相同或相似的概念或过程可能在 某些实施例不再赘述。
图4是本申请提供的传输方法一实施例的流程示意图。如图4所示,本实施例提供的方法可以应用于终端,该方法包括:
步骤101、接收指示信息,根据指示信息确定传输块的第一数量;指示信息用于激活配置授权;
具体的,终端接收指示信息,例如是网络设备发送的指示信息,该指示信息用于激活配置授权,例如包括配置授权的参数信息,终端根据该指示信息,确定传输块的第一数量,第一数量可以是一个或多个。
步骤102、根据传输块的第一数量,进行数据传输。
具体的,终端根据确定的第一数量进行数据传输,若第一数量为一个,则在一个CG周期内进行单TB传输;若第一数量为多个,则在一个CG周期内进行多TB传输。
如图5所示,例如第一数量为4,则根据指示信息确定第一数量后以4个TB进行上行传输,传输完成后监听网络设备发送的下行控制信息,网络设备除了在接收失败的情况下发送重传指示,其余的时机可以不用发送下行控制信息,节省信令开销。
该方式中,网络侧通过配置授权向终端分配资源,网络侧激活一次上行授权给终端,在终端不收到去激活的情况下,将会一直使用第一次上行授权所指定资源进行上行传输。
本实施例的方法,接收指示信息,根据所述指示信息确定传输块的第一数量;所述指示信息用于激活配置授权,由于配置授权只需激活一次就可以一直使用,除非进行去激活,因此只需一次指示信息,即可根据确定的传输块的第一数量进行上行数据传输,节省了下行信令开销。
在上述实施例的基础上,指示信息包括第一指示信息,或者,指示信息包括:第二指示信息,或者,指示信息包括第一指示信息和第三指示信息,或者,指示信息包括第三指示信息和第四指示信息,其中,
第一指示信息用于指示配置授权的第一公共参数信息;第一公共参数信息包括:传输块的第一预设数量;
第二指示信息用于指示第一类型配置授权的专用参数信息;专用参数信息包括:传输块的第二预设数量;
第三指示信息用于激活第二类型配置授权;
第四指示信息用于指示配置授权的第二公共参数信息;第二公共参数信息包括:重复传输次数。其中,第四指示信息可以不包括传输块的第一预设数量。
具体的,若指示信息包括第一指示信息,第一指示信息用于指示配置授权的第一公共参数信息;第一公共参数信息包括:传输块的第一预设数量。即配置授权的公共参数可以指示传输块的数量。
在一实施例中,所述指示信息包括第一指示信息,所述根据指示信息确定传输块的第一数量,包括:
将所述第一预设数量作为所述传输块的第一数量;或,
所述指示信息包括第二指示信息,所述根据指示信息确定传输块的第一数量,包括:
将所述第二预设数量作为所述传输块的第一数量。
对于第一类型type1的配置授权来说,终端可以根据第一公共参数信息中指示的第一预设数量,确定第一数量,即将第一预设数量作为第一数量。
若指示信息包括第二指示信息,第二指示信息用于指示第一类型配置授权的专用参数信息;专用参数信息包括:传输块的第二预设数量。即传输块的数量通过type1配置授权的专用参数指示。
对于第一类型type1的配置授权来说,终端可以根据第一类型配置授权的专用参数信息中指示的第二预设数量,确定第一数量,即将第二预设数量作为第一数量。
其中,在某些实施例中,第一预设数量和第二预设数量可能同时配置,则第一预设数量可以与第二预设数量相同,或不同。
若第一预设数量和第二预设数量不同,则对于终端来说,可以将第一预设数量或第二预设数量作为第一数量,本申请实施例对此并不限定。
在实际应用中,若第一预设数量或第二预设数量为空,按默认值X进行配置授权的单TB或多TB传输。默认值X可以是协议规定的预设数值的。
在一实施例中,所述指示信息包括第一指示信息和第三指示信息,或所述指示信息包括第三指示信息和第四指示信息,所述根据指示信息确定传输块的第一数量,包括:
若所述第三指示信息包括所述传输块的第二数量,则将所述第三指示信息包括的第二数量作为所述传输块的第一数量。
若指示信息包括第一指示信息和第三指示信息,即通过第一指示信息配置type1和type2配置授权的公共参数,通过第三指示信息激活type2配置授权。
对于第二类型type2的配置授权来说,若第三指示信息包括传输块的第二数量,则终端可以根据第三指示信息指示的第二数量确定第一数量,即将第二数量作为第一数量。
在某些实施例中,第一指示信息和第三指示信息均指示传输块的数量的情况下或只有第三指示信息指示传输块的数量的情况下,以第三指示信息中指示的数量为准,第二数量可以与第一预设数量不同。
在一实施例中,第二数量小于或等于传输块的第一预设数量。
具体的,若第一指示信息和第三指示信息均指示传输块的数量的情况下,第三指示信息指示的第二数量以第一指示信息指示的公共参数中的数量作为最大值,即不超过公共参数中的第一预设数量,例如公共参数中第一预设数量为4,则第三指示信息可以指示1,2,3,4;例如公共参数中第一预设数量为8,则第三指示信息可以指示1-8任一数值。
在其他实施例中,第二数量小于或等于协议规定的最大值,而不是配置的第一预设数量,例如第一指示信息中第一预设数量为4,第三指示信息中第二数量为8。
在一实施例中,若第三指示信息不包括传输块的第二数量,则终端可以根据第一指示信息指示的第一预设数量确定第一数量,即将公共参数中指示的传输块的第一预设数量作为第一数量。
若指示信息包括第三指示信息和第四指示信息,即通过第四指示信息配置type1和type2配置授权的公共参数,通过第三指示信息激活type2配置授权。
对于第二类型type2的配置授权来说,若第三指示信息包括传输块的第二数量,则终端可以根据第三指示信息指示的第二数量确定第一数量,即将第二数量作为第一数量。
在一实施例中,若第三指示信息指示传输块的数量的情况下,第三指示信息指示的第二数量以一个数量阈值作为最大值,即第二数量小于或等 于该数量阈值,该数量阈值为根据第四指示信息指示的重复传输次数得到。
在一实施例中,该数量阈值与重复传输次数成反比。
在一实施例中,重复传输次数可配置为1,2,4,8。
例如重复传输次数repK为1时,数量阈值可以为8,第三指示信息中的第二数量可以指示1-8任一个数值(整数),例如通过两比特指示1,2,4,8中一个数值;如果repK为2,则数量阈值可以为4,第三指示信息中的第二数量可以指示1-4任一个数值;如果repK为4,则数量阈值可以为2,第三指示信息中的第二数量可以指示1或2;以此类推。
在一实施例中,所述指示信息包括第三指示信息和第四指示信息,且所述第三指示信息中不包括所述传输块的第二数量,所述根据指示信息确定传输块的数量,包括:
根据所述重复传输次数,确定所述传输块的第一数量。
若第三指示信息不包括传输块的第二数量,则终端可以根据第四指示信息指示的公共参数确定第一数量,例如该公共参数为重复传输次数repK。
在一实施例中,可以根据重复传输次数,确定所述传输块的第一数量。
在实际应用中,避免过长时间发送上行数据,若重复传输次数较大,则可以减小多TB传输的传输块数量。若重复传输次数较小,则可以适当增大多TB传输的传输块数量。
在一实施例中,传输块的第一数量与所述重复传输次数成反比。
在一实施例中,重复传输次数可配置为1,2,4,8。
例如重复传输次数repK为1时,第三指示信息中的第二数量可以为8;如果repK为2,则第三指示信息中的第二数量可以为4;如果repK为4,则第三指示信息中的第二数量可以为2;以此类推。
在该方式中,激活type2的第三指示信息中没有指示传输块的数量,则可以通过type1和type2配置授权的公共参数中的某些参数隐式的得到传输块的第一数量,例如通过重复传输次数隐式得到传输块的数量。
在一实施例中,第一指示信息由高层信令承载,例如由RRC信令承载;
在一实施例中,第二指示信息由高层信令承载,例如由RRC信令承载;
在一实施例中,第四指示信息由高层信令承载,例如由RRC信令承载;
在一实施例中,第三指示信息由下行控制信息(DCI)承载。
对于第二类型type2的配置授权来说,在其他实施例中,协议中可以 规定一个默认的最大的传输块的数量,比如8。例如通过DCI的两比特信息指示传输块的第一数量,则可以通过两比特指示{1,2,4,8}四种选项。或,也可以通过更多的比特指示第一数量。但第一数量不能超过默认的最大的传输块的数量。
上述具体实施方式中,公共参数的相同字段在不同类型的配置授权下对应不同功能,可以增加configured grant的配置灵活性,尽可能地合理利用空口资源,而且提升了配置授权的上行数据率,同时节省了下行信令。
在一实施例中,指示信息中还可以包括多传输块传输的使能指示信息,例如该使能指示信息可以承载在第一指示信息或第四指示信息中。
步骤102可以通过如下方式实现:
根据使能指示信息和传输块的第一数量,进行数据传输。
具体的,在进行数据传输前可以确定使能指示信息是否使能多传输块传输的方式,若使能,且第一数量为多个,则按照第一数量进行多传输块传输。
若未使能,则按照单传输块传输。
在一实施例中,步骤102之前还进行如下操作:
确定是否激活动态调度的多传输块传输方式;
若激活动态调度的多传输块传输方式,则根据所述传输块的第一数量,进行数据传输。
具体的,如果动态调度没有激活多TB传输,则DL所需子帧较多。比如configured grant一次传4个TB,如果都出错了,那就需要4个DCI来指示重传4个TB,如果动态调度激活多TB传输,比如configured grant一次传4个TB,如果都出错了,那就只需要1个DCI来指示重传4个TB。因此,在动态调度激活多TB传输的情况下配置授权激活(或使能)多TB传输才生效,即在动态调度激活多TB传输的情况下才按照前述实施例中任一方式确定第一数量,并进行数据传输,否则终端在配置授权的方式下不以多TB的方式上传数据,这时默认的第一数量依然是1。
上述具体实施方式中考虑了将动态调度多TB传输是否激活来作为配置授权的多TB传输是否激活的一个前提条件,增加重传时的效率并节省信令。
在一实施例中,多传输块传输的使能指示信息Multi-TB enable/disable 和第一预设数量TB number1是configured grant中的公共参数:
对于type1 configured grant(rrc-ConfiguredUplinkGrant存在)
若Multi-TB enable,且TB number1非空,按公共参数中TB number1进行configured grant多TB传输。
若Multi-TB enable,且TB number1为空,按默认值X进行configured grant单或多TB传输(协议规定的默认值)。
对于type2 configured grant(rrc-ConfiguredUplinkGrant不存在)
若激活type2配置授权的DCI中不存在第二数量TB number2域,第一数量按公共参数来确定(第一预设数量或重复传输次数)。
若激活type2配置授权的DCI中存在TB number2域(公共参数Multi-TB enable,DCI中TB number2域才存在):。
1、DCI中TB number2域指示的第二数量覆盖公共参数TB number1,以DCI中指示的值为准(如RRC指示TB number1为4,DCI可以指示TB number2为8,例如8为规定的上限)。2、DCI中TB number2可指示的TB number2值以公共参数中的TB number1作为最大值(如公共参数指示TB number1为4,DCI可以指示1,2,3,4)
在一实施例中,DCI中可指示的TB number2还可以根据公共参数中的其他域隐式得到。
如果Multi-TB enable/disable是configured grant中的公共参数,TB number1是rrc-ConfiguredUplinkGrant中的参数:
对于type1 configured grant,rrc-ConfiguredUplinkGrant存在:
若Multi-TB enable,且TB number1非空,按TB number1进行configured grant多TB传输。
若Multi-TB enable,且TB number1为空,按默认值X进行configured grant单或多TB传输(默认值可为1或非1)。
对于type2 configured grant,rrc-ConfiguredUplinkGrant不存在:
若激活type2配置授权的DCI中存在TB number2域(公共参数Multi-TB enable,DCI中TB number2域才存在):
1、协议默认一个最大的TB number3。比如8,这时DCI中可以指示的TB number2以TB number3为最大值,例如默认两比特指示{1,2,4,8}四种选项。
2、隐式指示:根据重复传输次数repK隐式确定。例如repK可配置为1,2,4,8,为避免过长时间发送上行数据,考虑数量阈值max TB number与repK成反比:比如repK为1时,max TB number为8,例如可以通过DCI两比特指示1,2,4,8,或者通过更多比特指示下小于或等于8的整数;如果repK为2,则Maximum TB number为4,例如可以通过DCI 2比特指示1,2,3,4;如果repK为4,则Maximum TB number为2,例如可以通过DCI 2比特指示1,2;以此类推。
若激活type2配置授权的DCI中不存在TB number2域:公共参数Multi-TB enable时,type2配置授权的TB number2确定方式。
1、协议默认一个TB number4。比如8,这时DCI激活configured grant后按协议默认的TB number4来传输。
2、隐式指示:根据repK隐式确定。repK可配置为1,2,4,8,为避免过长时间发送上行数据,考虑type2的TB number2与repK成反比:比如repK为1,TB number2为8,DCI激活的configured grant传输的TB数为8;如果repK为2,TB number2为4,DCI激活的configured grant传输的TB数为4;如果repK为4,TB number2为2,DCI激活的configured grant传输的TB数为2;以此类推。
上述实施例中,公参数中的TB数域对于不同类型的configured grant有不同的功能,对于Type1其表示需要传输的TB数,对于Type2其表示DCI中可指示的值,或可指示的最大值。
