还例如,某个SRS序列对应梳状资源(Comb)数等第一传输对应Comb数,则可根据第一传输
确定的Comb数确定请求第二传输的SRS的序列。
所述Comb数域最大CS数量基于如下表格确定:
其中,KTC是CS的最大值。
值得注意的是:S2101可为可选步骤,例如,终端和网络设备可以基于预定义方式确定第一传输的传输参数,此时网络设备发送配置信息的步骤可省略。

在一些实施例中,下行传输的发送参数可为下行传输的发送密度和/或发送的下行传输的索引。
如图4D所示,假设第一传输为SRS,SRS的不同序列则可对应于下行传输不同密度。例如,第一网络设备和/或第二网络设备在未接收到作为第一传输(即图4D中的WUS)时,SSB关闭。此处的SSB关闭为不发送SSB。在接收到为序列1和/或序列2的SRS之后,网络设备在一个周期内发送2个SSB。在接收到为序列3的SRS之后,网络设备在一个周期内发送4个SSB。例如,如图4D所示,序列1和序列2的SRS可用于触发网络设备发送不同索引的SSB。
在一些实施例中,终端使用不同的波束发送第一传输,可对应于向第一网络设备和/或第二网络
设备请求不同的下行传输。
S2103:网络设备向终端发送第二传输。

物理下行控制信道(Physical Downlnk Control Channel,PDCCH)信息和/或物理下行共享信道(Physical DownlnkShared Channel,PDSCH)信息。在一些实施例中,若第二传输包括SIB,则第二传输可至少包括SIB1。通常情况下SIB1可用于配置其他SIB的传输,因此对于终端而言SIB1更为重要。
在一些实施例中,该发送第二传输的网络设备可为当前处于休眠状态的网络设备。
在一些实施例中,该发送第二传输的网络设备可为当前在执行NES机制的网络设备。
在一些实施例中,该发送第二传输的网络设备可为当前正在执行网络节能(Network Energy Saving,NES)机制的网络设备。示例性地,该网络节能机制可包括但不限于:小区的非连续发送、小区的非连续接收、小区的间歇性激活等。
当然在另一些实施例中,该网络设备也可以是出于工作状态的网络设备,即该网络设备既没有休眠,也没有执行NES机制。
在一些实施例中,该发送第二传输的网络设备可为基于按需模式发送下行传输的网络设备。

在一些实施例中,网络设备在接收到第一传输之后,可根据请求发送的第二传输的重要性(可由第二传输的功能体现)和/或网络设备的当前状态,确定是否向终端发送第二传输。
在确定向终端发送第二传输时,则向终端发送第二传输,否则不向终端发送第二传输。
示例性地,第一传输可携带指示请求的第二传输的标识信息,网络设备可根据标识信息确定待传输的第二传输,根据第二传输的功能以及当前自身是否处于休眠状态、或预计自身维持NES执行的持续时长等,综合确定是否发送第二传输。
又示例性地,网络设备收到第一传输根据自身的状态切换,确定自身将很快退出不发送或者按需发送第二传输的NES机制,则网络设备可以提前退出NES机制以响应终端的请求,或者,网络设备可以等待原定退出NES机制的时间退出NES机制,再按照半静态周期或者动态配置周期发送第二传输。
在还有一些实施例中,网络设备可以根据小区内请求同一个第二传输的终端数和/或请求次数等请求状况,确定是否向终端发送第二传输。
在另一些实施例中,网络设备在接收到第一传输,就确定发送第二传输。
在一些实施例中,网络设备在接收到第一传输之后,在第二传输的第一时间窗口内向终端发送第二传输。

在一些实施例中,终端在前一次第一传输发送之后的第一时间窗口内接收第二传输但接收失败或者第二传输解码失败时,继续向第一网络设备发送第一传输。
在一些实施例中,该第一时间窗口可为由预定义确定,例如,第一时间窗口可由协议约定。又例如,该第一时间窗口可是终端和网络设备共同知晓的默认窗口。
在一些实施例中,该第一时间窗口可由网络设备配置,例如,可以前述配置信息中的某一个信息或多个信息定义。
在另一些实施例中,该第一时间窗口还可由携带前述配置信息以外的网络信令指示。该网络信令可包括物理层信令和/或高层信令。该物理层信令可包括但不限于下行控制信息。该高层信令可包括但不限于RRC信令。
终端继续发送的第一传输,依然用于触发第一网络设备和/或第二网络设备发送第二传输。
在一些实施例中,若终端尚未接收到所有的第二传输,继续发送的第一传输可用于请求剩余未接收到的第二传输。
在一些实施例中,终端还可以通过重新发送第一传输请求新的第二传输。
值得注意的是:S2101、S2103以及S2104均可为可选步骤。例如,第一传输的传输参数采用预定义方式确定,则网络设备无需向终端发送配置信息,则S2101可省略。又例如,网络设备接收到第一传输之后可根据实际网络情况确定不发送第二传输,继续维持网络设备的低功耗状态实现网络更好的节能效果,则S2103可省略。在一些实施例中,若网络设备未配置第一时间窗口或者未预定义第一时间窗口,则终端在发送第一传输之后的第一时间窗口内未接收到第二传输时,可以不再继续发送第一传输,可默认为等待网络设备自行发送第二传输等,因此S2104可省略。
如图3A所示,本公开实施例提供一种下行传输触发方法,可由终端执行。该方法可包括:
S3101:接收配置信息。
在一些实施例中,如图3B所示,终端接收第二网络设备发送的配置信息。
在一些实施例中,如图3C所示,终端接收第一网络设备发送的配置信息。
在一些实施例中,该配置信息可用于终端发送第一传输。
该配置信息的信息内容可参见图2对应实施例的相关描述,此处就不再重复了。
在一些实施例中,该S3101可省略,第一传输的传输参数可以根据预定义方式确定。
值得注意的是:该S3101可单独作为一个实施例执行,终端接收到配置信息之后,但是并未发送第一传输。
S3102:发送第一传输。
在一些实施例中,终端向第一网络设备发送第一传输。
在一些实施例中,终端根据配置信息或预定义确定第一传输的传输参数,根据确定的传输参数向第一网络设备发送第一传输。
该第一传输,用于触发第一网络设备和/或第二网络设备发送第二传输。
此处第一网络设备和/或第二传输的相关描述可以参见图2对应的实施例。
此处终端发送第一传输的可选实施方式可参见图2对应实施例的S2102。
值得注意的是:该S3102可单独作为一个实施例执行,也可以与S3101组合实施。
S3103:接收第二传输。
在一些实施例中,在发送第一传输之后接收第二传输。
在一些实施例中,在发送第一传输的第一时间窗口内接收第二传输。
在一些实施例中,该第一时间窗口的相关描述可以参见图2对应的实施例。
值得注意的是:该S3103可单独作为一个实施例执行,例如其他终端向网络设备发送了第一传输且第二传输是被广播的,则此时S3103可单独执行。在一些实施会中,S3103可与S3101至S3102中的一个或两个组合实施。
如图3D所示,终端从第一网络设备接收第二传输。
示例性地,若第一网络设备接收的第一传输中携带有与第二网络设备相关的标识信息,则可第一网络设备会认为第一传输是请求第二网络设备发送第二传输,则第一传输会被第一网络设备转发或透传至第二网络设备,如此,终端将接收到第二网络设备发送的第二传输。
在一些实施例中,与第二网络设备相关的标识信息可包括但不限于以下至少之一:
第二网络设备的设备标识,例如,基站标识;
第二网络设备的小区标识。
在一些实施例中,第一网络设备可作为常规小区的网络设备。该常规小区可为周期性发送下行传输的小区。该常规小区关联有一个不会周期性发送下行传输的小区A。此时,第一网络设备接收到第一传输,就默认是请求小区A的下行传输,因此第一网络设备会将第一传输转发或透传至第二网络设备。故终端会收到第二网络设备发送的下行传输。
值得注意的是:该S3102和S3102组合实施,也可以与S3101至S3102组合实施。
如3E所示,终端从第二网络设备接收第二传输。
S3104:继续发送第一传输。
在一些实施例中,终端继续向第一网络设备发送第一传输。
在一些实施例中,终端未接收到第二传输或接收到的第二传输解码失败,继续发送第一传输。
在一些实施例中,终端在发送第一传输之后的第一时间窗口内未接收到第二传输,继续发送第一传输。
此处终端继续发送第一传输的可选实施方式可参见图2对应实施例的S2104。
值得注意的是:该S3104可与S3102组合施例,或S3104可与S3101和S3102组合实施。
值得注意的是:S3101、S3103以及S3104均可为可选步骤。例如,第一传输的传输参与采用预定义方式确定,则终端无需从网络设备接收配置信息。网络设备在接收到第一传输之后确定不第二传输,则终端无法接收到第二传输。或者终端获取第二传输的需求消失,则终端可以不执行S3103。若终端不再有第二传输的获取需求、第一时间窗口未被配置或未被预定义,则终端也可无需继续发送第一传输。例如,终端发送指定次数第一传输之后依然没有接收到第二传输,可默认网络设备不会发送第二传输,为了避免无线环境的干扰,则不再继续发送第一传输,从而S3104可省略。该指定次数可为1次或多次。
如图4A所示,本公开实施例提供一种下行传输触发方法,可由第一网络设备执行。该方法可包括:
S4101:发送配置信息。
在一些实施例中,第一网络设备向终端广播、组播或单播配置信息。
在一些实施例中,该配置信息的信息内容和/或携带信令都可以参见图2对应的实施例。

在一些实施例中,第一网络设备向第二网络设备发送第一传输。如图4C所示,第一网络设备向第二网络设备发送第一传输。
在一些实施例中,若第一传输同时向第一网络设备和第二网络设备请求第二传输,则第一网络设备在自身向终端发送第二传输的同时,将第一传输转发给第二网络设备,以触发第二网络设备发送第二传输。
在一些实施例中,第一网络设备向第二网络设备透传或转发第一传输。例如,第一网络设备基于与第二网络设备之间的基站间接口向第二网络设备发送第一传输。又例如,第一网络设备基于与第二网络设备之间的隧道向第二网络设备发送第一传输。
值得注意的是:该S4104可与S4102组合式实施例,也可以是S4104、S4101及S4102三者组合实施例。
S4105:继续接收第一传输。
在一些实施例中,在接收到前一个第一传输后间隔第二传输的第一时间窗口后,继续接收第一传输。

该第二传输的第一时间窗口可参见图2对应的实施例。
在一些实施例中,S4101、S4103以及S4104至S4105均可为可选步骤。例如,第一传输的传输参与采用预定义方式确定,则第一网络设备无需发送配置信息。又例如,配置信息由第二网络设备发送,则第一网络设备也无需发送配置信息。因此S4101可省略。第一网络设备在接收到第一传输之后确定不第二传输,则S4103可省略。若第一传输用于触发第二网络设备发送第二传输,则同样可省略S4103。若第一传输请求第一网络设备发送第二传输,则S4104可省略。若终端不再有第二传输的获取需求、第一时间窗口未被配置或未被预定义,则第一网络设备也可无需继续发送第一传输,则S4105可省略。例如,终端发送指定次数第一传输之后依然没有接收到第二传输,可默认网络设备不会发送第二传输,为了避免无线环境的干扰,则不再继续发送第一传输,从而S4105可省略。该指定次数可为1次或多次。
如图5所示,本公开实施例提供一种下行传输触发方法,可由第二网络设备执行。该方法可包括:
S5101:发送配置信息。
在一些实施例中,第二网络设备向终端广播、组播或单播配置信息。

值得注意的是:该S5104可与S5102组合作为一个实施例实施、也可以与S5102以及S5103组合实施,还可以与S5101、S5102以及S5103组合实施。
在一些实施例中,S5101、S5103以及S5104至S5105均可为可选步骤。例如,第一传输的传输参与采用预定义方式确定,则第二网络设备无需发送配置信息。又例如,配置信息由第一网络设备发送,则第二网络设备也无需发送配置信息。因此S5101可省略。第二网络设备在接收到第一传输之后确定不第二传输,则S5102和S5103可省略。若第二网络设备确定不发送第二传输,则S5103可省略。若终端不再有第二传输的获取需求、第一时间窗口未被配置或未被预定义,则第二网络设备也可无需继续接收送第一传输,则S5105可省略。
第二传输可包括下行参考信号和/或下行信息,以下对下行参考信号中的SSB和/或SRS的配置进行相关介绍。
网络设备基于业务需求情况等,停止发送对应的SSB。
终端在SSB的接收期间无法接收对应SSB。若终端期望可以接收到对应SSB,则UE发送对应的唤醒信号(wake up signal,WUS)信号给网络设备。该WUS信号可为前述第一传输中参考信号的一种。
网络设备可基于终端的WUS选择是否继续发送SSB。
若网络设备确定发送SSB,网络设备发送对应的确认(acknowledgement character,ACK),确定传输SSB。
终端在发送WUS后开始尝试接收SSB和/或ACK。此时终端可接收对应ACK后,开始尝试接
收SSB。
在一些实施例中,SSB可周期性或非周期性发送。
SSB图样(pattern)可与子载波间隔(sub Carrier Space,SCS)等有关,SSB的发送周期为20ms,具体的图样可如下表所示:
SSB配置方式可如下:
首先,SSB可用于小区搜索。
其次,终端可通过S1B1获取SSB的配置。
例如,通过SSB的服务小区配置SIB(ServingCellConfigCommonSIB)信息单元携带SSB的配置信息。
该ServingCellConfigCommonSIB信息单元可如下:
注:SSB突发(ssb-PositionsInBurst)可包括两个字段,分别是:在一个组(inOneGroup)字段和组呈现(groupPresence)字段。这两个字段都可包括8个比特的比特字符串(BIT STRING)。
在一个周期内SSB突发有64个时,则inOneGroup字段中一个比特的不同值,可指示一个突发组的SSB突发是否发送。一个突发组可包括8个SSB突发。此时,groupPresence字段的8个比特分别指示inOneGroup字段指示发送的突发组中各个SSB突发是否发送。
在一个周期内SSB突发有16个时,则inOneGroup字段和groupPresence字段分别指示8个SSB突发是否发送。
ssb-PeriodicityServingCell字段指示SSB发送周期。
3)基于服务小区公共配置(servingcellConfigCommon)IE进行SSB配置。
servingcellConfigCommon IE可如下:
一个SSB突发(burst)内包含4、8或64个SSB。服务小区SSB周期(ssb-periodicityServingCell)
字段配置的SSB的发送周期。
SSB频域位置可采用如下方式确定:
SSB频域范围基于终端通过在对应频域范围搜索盲检对应的SSB确定。
在一些实施例中,SSB在频域上占据20个资源块)(Resource Block,RB)。
SIB1配置方式:
1)方式一:基于主信息块(Master Information Block,MIB)配置SIB1。
MIB内的物理下行控制信道配置SIB1(pdcch-ConfigSIB1),用于指示调度SIB1的DCI format0_1(SI-RNTI)加扰的控制资源集(CORESET)#0和搜索空间(SearchSpace)#0。SIB1的缺省(default)周期可为20ms,终端盲检对应的下行控制信息(Downlink Control Information,DCI)获取SIB1的传输指示,在DCI指示传输SIB1时,则终端指示的位置接收对应的物理下行共享信道信息,解析物理下行共享信道信息得到SIB1。
2)方式二:基于SIB1指示的服务小区配置功能SIB(servingCellConfigCommonSIB)内的物理下行控制信道配置公共(PDCCH-configCommon)IE配置SIB1。
PDCCH-configCommon IE包含:搜索空间(searchspace,SS)SIB1配置和/或控制资源集(CORESET)#0和搜索空间(SearchSpace)#0的配置。
对应辅小区的SIB1获取,一为通过服务小区公共(servingcellConfigCommon)IE配置二为通过专用SIB1传输(dedicatedSIB1-Delivery)IE配置。
SRS基于如下方式配置:
ServingCellConfig->UplinkConfig->BWP-Uplink->BWP-UplinkDedicated->SRS-config。
ServingCellConfig IE包含UplinkConfig IE。
UplinkConfig IE包含BWP-Uplink IE。
BWP-Uplink IE包含BWP-UplinkDedicated IE。
BWP-UplinkDedicated IE包含SRS-config IE。该SRS-configIE为SRS的配置信息。
SRS对应功能(usage)可如下:
基于SRS应用场景的不同,包含以下几种:
{波束管理(beamManagement),码本(codebook),非码本(nonCodebook),天线切换(antennaSwitching)},具体场景基于功能配置。
SRS所在频域位置可由RRC信令配置确定:
SRS所在RB位置可用如下方式确定:
SRS所占RB数可基于c-SRS确定,所述c-SRS基于高层信令配置。SRS的RB起始位置基于频移(freqDomainShift(nshift))确定。
在的条件下,对应SRS参考位置为CRB#0的子载波0的位置,否则SRS频域起始参考位置为所在激活BWP的最低位置。
SRS所在RE位置:SRS所在RE起始位置KTC∈{2,4,8}决定SRS传输的梳齿,以KTC=2为例,对应RB内SRS每隔2个RE传输,所述两个参数基于高层参数transmissionComb确定。
SRS所在时域位置可由RRC信令配置确定。
对于周期和半静态的SRS,其所在时隙t可基于半静态周期和偏移量(SRS-PeriodicityAndOffset)配置,SRS在时隙内的符号起始位置和所占符号长度基于起始位置(startPosition)字段和符号数(nrofSymbols)字段指示。对于AP SRS,对应SRS传输基于DCI触发。
SRS触发方式:
对于半静态的SRS,对应SRS传输基于MAC CE触发,以SRS资源集(SRS resource set)为粒度。
对于非周期(即动态)的SRS,基于DCI 0_1或DCI 0_2中的SRS request触发,触发对应的SRS resource set的传输。
SRS序列:
对应SRS序列基于ZC序列确定,所述序列与天线端口CSαi以及传输梳状值Comb KTC∈{2,4,8}有关。
终端侧的下行传输处理方法可如下:

实施方式:
假设终端为Rel-18及后续版本终端,且终端为支持NES特性的终端。为支持网络节能的需求,考虑到网络设备在一定时间内可能放弃发送对应的系统信息,例如,SSB和/或SIB1/SIBn,或者放弃接收对应的上行信号,例如,RACH等,终端需要基于对应的网络侧行为放弃系统信息的接收,或者,上行信号的传输。值得注意的是,本公开实施例方案除了应用在NES场景中,还可应用在其他场景中,本公开实施例方案对此不作限制。
若网络设备在一定时间内放弃发送对应的信息,信息可以称为on-demand信息,本公开实施例方案以SSB和SIB1为例,信息为按需(on-demand)SSB和/或SIB1,阐述本公开实施例方案。对于其他的信息,也在本公开实施例方案的保护范围在内,在此不再赘述。
本公开实施例方案涉及的on demand SSB/SIB的状态指示,包括以下至少之一:
基站不发送SSB且不传输SIB1;
基站不发送SSB且发送SIB1;
基站发送SIB1且不发送SSB;
基站发送SSB且按需发送SIB1;
基站发送SIB1且按需发送SSB。
本公开实施例方案主要针对基站不传输SSB,或SIB1的状态下,终端需要对应SSB和/或SIB1发送的系统消息的条件下,发送对应的参考信号,用于请求基站传输对应SSB和/或SIB1。
本公开实施例方案主要设计参考信号,实现上述信息请求过程。基于此,与本公开实施例相关的过程如下所示:
步骤1:终端确定用于触发请求的SRS的配置信息。配置信息可以基于信令配置或预定义方式确定,具体实施场景可能包括以下一种或多种:
实施例1-2:
在本实施例中,假设基站为支持网络节能技术的基站。基站能够根据网络负载、驻留终端数目、业务类型、服务时段等选择停止发送部分下行信号或者信道。当然,对于基站是否发送部分下行信号或者信道的决策过程和策略本公开实施例不做任何限定。基站接收到终端发送的指示信息后,可根据终端的请求信息,选择恢复发送下行信号或者信道。在本实施例中,根据终端请求,基站确定发送如下下行信号或者信道任意之一或者任意组合:SSB、SIB1、TRS、PDCCH、PDSCH、CSI-RS。
在一些实施例中,该下行信号还可包括:PSS和SSS,DRS等。
在一些实施例中,该下行信号还可包括其他新定义的下行参考信号。
在本实施例中,终端通在PUCCH上发送PUCCH信息,通过PUCCH信息请求基站发送下行信号和/或信号。在本实施例中,终端通过参考信号承载请求信息。在后续描述中称之为参考信号。
此处的PUCCH信息为前述第一传输的一种。在一些实施例中,该第一传输还可包括各种参考信号。以下以参考信号为例进行举例说明,具体实现时下列实施例中的参考信号都可以替换成“第一传输”。
在本实施例中,终端在周期性出现的参考信号发送资源上发送特定的参考信号,参考信号用于请求基站发送下行信号和/或信道。发送参考信号资源用于终端发送请求第二传输的各种类型的参考信号和/或上行信息。
在本实施例中,终端通过如下方法确定用于请求基站下行传输的参考信号所占时频资源。本公开实施例对于终端的状态不做任何规定,例如本公开实施例可应用于连接态终端,亦可应用于空闲态(IDLE)或者非激活态(INACTIVE)终端。本公开实施例对于发送参考信号时频资源的配置来自于何种基站亦不做任何限定,例如本公开实施例中的相关配置信息可由终端请求下行传输的基站发送,亦可用其他基站发送。
根据基站发送的小区专用(specific)信令中的配置信息确定,本公开实施例不限定小区-specific信令的类型,例如SIB1或者其他SIB。或者,根据基站发送的UE-dedicated RRC signalling中的配置信息确定。或者,通过协议预定义的方式确定,也即终端在协议中规定好的默认(default)资源上发送参考信号。该参考信号可用于请求基站下行传输。
由于用于请求基站下行传输传输的参考信号的资源,可能与用于发送CSI或者HARQ确认信息
或者SR信息的资源冲突。在此场景下,本公开实施例假设终端在资源上按照需要发送CSI或者HARQ确认或者SR信息。或者,在此场景下,本公开实施例假设终端在资源上发送参考信号。
在本公开实施例中,参考信号的发送资源可包括但不限于PUCCH资源。例如,在一些实施例中,该参考信号的发送资源还可包括PRACH资源。
对于用于发送参考信号的发送资源,其为通过前述任意方法配置或者确定的额外发送资源,该发送资源也即不同于传统的用于承载ACK/NACK或者调度请求(SR)的资源。或者,用于发送参考信号的发送资源与现有(legacy)发送资源共享,也即通过前述任意方法之一,在发送资源集(set)中选取一个或者多个发送资源用于发送请求基站下行传输的指示信息。在此假设下,基站需要告知终端用于发送请求基站下行传输指示信息的发送资源标识,且发送资源不能用来发送CSI信息或者HARQ确认信息或者SR的资源。或者,终端需要通过预定义的方式确定用于发送下行传输指示信息的发送资源标识,例如,集合中标识最小或表示最大的发送资源。
基于如上假设和配置,终端在参考信号资源上,在需要请求基站侧发送对应下行信号或者信道时,发送承载请求基站下行传输请求信息的参考信号。在本实施例中,假设终端在资源上发送特定的参考信号,用于请求基站发送下行信道或者信号。信息参考信号用于请求基站发送SSB,或者SIB1,或者SSB和SIB1,或者特定波束(beam)对应的SSB,波束(beam)对应的SIB1,或者,特定波束对应的SSB或者SIB1、或者其他任意下行信道和/或信号的组合,如前。
用于请求基站进行下行信号或者信道发送的第一传输参考信号,可通过协议预定义的方式确定,例如,可以通过协议约定等预定义方式约定参考信号的长度以及特定比特组成的信息,例如,‘00000000000’;亦可通过基站进行配置,也即基站指定何种比特指示对应的信息用做参考信号。
进一步地,特定参考信号可对应于下行信号和/或信道的发送波束,例如对应的一个或者多个SSB索引(index)。前述参考信号与终端请求的信号和/或信道的对应关系通过高层信令进行配置或者通过协议预定义的方式确定。
进一步地,第一传输可以用于请求特定波束的SSB和/或SIB1,波束与第一传输使用的波束准共址,本公开实施例不做任何限定。
当终端处于空闲态和/或非激活态时,配置信息不释放,终端仍可根据配置信息在对应时频资源上发送PUCCH format#2,用于请求基站发送对应的下行信号或者信道。
进一步地,终端发送参考信号后,在T之后的第一个请求的下行信道和/或信号传输时域资源位置检测接收对应的下行信道和/或信号。T根据终端能力确定,或者通过基站发送的配置信息确定。该T可对应于前述第一时间窗口。即第一时间窗口可根据终端的能力和/或基站和终端之间收发信息单侧时间间隔确定。
基站检测接收到终端发送的参考信号后,发送终端请求的下行信号或者信道。
参考信号当然下行信道可为前述信道或者信号的任意一种或者任意组合,本公开实施例不做任何限定。另外,以SSB为例,在SSB关闭(OFF)期间,基站可选择性的发送其他的信号或者信号,本公开实施例亦不做任何限定。在如下例子中,假设终端可通过八种不同的信息参考信号向基站请求SSB的发送。示例性地,在信息所占比特等于3比特,示例性地,假设此时SSB的传输图样为case A,且为3GHz以下,因此系统内的SSB为4个。在本例中假设终端发送参考信号和SSB的对应关系如下,对应关系通过前述任意方法确定:
000对应于SSB#0和SSB#1;
001对应于SSB#2和SSB#3;
010对应于SSB#0、SSB#1、SSB#2和SSB#3;
011对应于SSB#0;
100对应于SSB#1;
101对应于SSB#2;
110对应于SSB#3。
为了全面的示例性说明本实施例方案,假设终端在三个不同的参考信号传输位置发送了不同的参考信号,当基站未接收到任何终端发送的任何参考信号时,基站不需要发送SSB。当基站接收到终端发送的参考信号对应‘000’时,则发送SSB#0和SSB#1;当基站接收到终端发送的参考信号对应‘001时,则发送SSB#2和SSB#3;当基站接收到终端发送的参考信号对应‘010时,则发送SSB#0、SSB#1、SSB#2和SSB#4。其他指示信息类似,在此不再赘述。
当然如前,本公开实施例方法不限定为SSB,也不限定参考信号和下行信号的对应关系。例如,在本例中假设终端发送参考信号和SIB1的对应关系如下,对应关系通过前述任意方法确定:
000对应于波束#1发送的SIB1;
001对应于波束#2发送的SIB1;
010对应于波束#3发送的SIB1;
011对应于波束#4发送的SIB1;
100对应于全不波束发送的SIB1。
实施场景一:
终端基于小区1获取对应的SRS的配置信息,并在小区2上需要请求小区2对应的基站发送SIB1时,在小区1上发送对应的小区1的SRS请求信息。
在此场景下,小区2为以on demand模式传输SSB和/或SIB1的小区,示例性地,小区可以被称为非锚点小区。终端在需要对应SIB1传输时,需要发送对应的SIB1/SSB请求信息。
在此场景下,小区1可以为正常发送SSB和/或SIB1的小区,示例性地,小区可以被称为锚点小区。
锚点小区可以配置一个或多个其他小区(例如,非锚点小区)的用于SIB1/SSB请求的SRS配置。同时,也会接收对应多个非锚点小区的SIB1/SSB请求信息。
示例性地,UE在小区1上发送针对小区2的SIB1/SSB请求信息,小区1对应的基站接收请求信息后,会将上述请求信息传递给小区2对应的基站。小区2对应的基站接收上述请求信息后,可以按需决定是否发送SSB、SIB1;
用于SIB1/SSB请求的SRS配置可以包含以下一种或多种参数:
小区ID:小区ID为非锚点小区的标识;
频率信息:非锚点小区使用的频点、频段或载波的频率;
SSB:非锚点小区对应的SSB相关信息,例如,SSB index和/或频域范围等。
SRS对应的时频域资源:起始频域资源单元、频域所占RB数、对应Comb数、SRS符号长度、SRS符号起始位置、SRS传输时隙、周期、跳频(Frequency Hop,FH)等,具体描述见实施例1和实施例2、在此不再赘述。
SRS对应的序列信息:SRS对应端口数、SRS对应CS、SRS对应Comb数等,具体描述见实施例1和实施例2,在此不再赘述。
SRS对应的功能:beamManagement、codebook、nonCodebook、antennaSwitching或其他新定义usage,具体见实施例1和实施例2;
UE确定上述配置后,可以基于配置信息传输对应的参考信号。
一种可能的实施方式,请求信息SRS对应的小区可以基于预定义方式确定。示例性地,不同小区跟不同CS相关联,在终端想请求小区2的SIB1的条件下,可以小区2对应的CS生成SRS序列。
基站接收上述SRS序列后,也可以基于CS确定对应关联的小区。从而执行后续操作。
实施场景二:
终端基于小区1获取对应的SRS的配置信息,并在小区2上需要请求小区2对应的基站发送SIB1时,在小区2上发送对应的小区2的SRS请求信息。
在此场景下,小区2为以on demand模式传输SSB和/或SIB1的小区,示例性地,小区可以被称为非锚点小区。终端在需要对应SIB1传输时,需要发送对应的SIB1/SSB请求信息。
在此场景下,小区1可以为正常发送SSB和/或SIB1的小区。
示例性地,小区1可以被称为锚点小区。锚点小区可以配置一个或多个其他小区(例如,非锚点小区)的用于SIB1/SSB请求的SRS配置。
示例性地,UE在小区1上获取对应的SRS配置,并基于上述配置在小区2发送对应的SIB1/SSB请求信息,小区2对应的基站接收上述请求信息后,可以按需决定是否发送SSB、SIB1;
用于SIB1/SSB请求的SRS配置与实施场景一类似,在此不再赘述。
如上,UE确定上述配置后,可以基于配置信息传输对应的SRS。
实施场景三:
终端基于小区2获取对应的SRS的配置信息,并在小区2上需要请求小区2对应的基站发送SIB1时,在小区2上发送对应的小区2的SRS请求信息。
在此场景下,小区2为以on demand模式传输SSB和/或SIB1的小区。并且,小区2需要配置对应的SRS配置信息,终端在需要对应SIB1传输时,需要发送对应的SIB1/SSB请求信息。
在此场景下,小区2可能需要终端在获取SIB1之前获取对应的SRS配置信息。据此,SRS配
置信息需要通过SSB(例如,MIB)配置或新定义下行Common信令确定。配置信息基于实施例1和实施例2确定,在此不再赘述。
一种可能的实施方式,基于预定义方式确定SRS配置信息的pattern,pattern可以基于配置信息确定,配置信息基于实施例1和实施例2确定,在此不再赘述。
一种可能的实施方式,小区2基于pdcch-ConfigSIB1配置确定预定义pattern中的一种。
值得注意的是,在UE获取SIB1之前,UE无法获知initial UL BWP对应的频域信息。只能获知SSB的频域信息,SRS的资源位置可能以SSB对应的频域信息为参考位置,具体见实施例1和实施例2方式定义,在此不再赘述。
值得注意的是,在UE获取SIB1之前,UE无法获知TDD相关的配置的信息,只能获知SSB的时域信息,SRS的时域位置可能以SSB对应的时域位置为参考位置,具体见实施例1和实施例2方式定义,在此不再赘述。
从终端角度来说,在终端确定小区2处于SSB和/或SIB1 off的条件下,终端基于pdcch-ConfigSIB1确定SRS配置信息,或确定配置信息的pattern,并基于配置信息传输SRS请求SSB和/或SIB1传输。
实施场景四:
终端基于预定义方式确定SRS配置信息,并在小区2上需要请求小区2对应的基站发送SIB1时,则终端在小区2上发送对应的小区2的SRS。
在此场景下,小区2为以on demand模式传输SSB和/或SIB1的小区。并且,小区2需要配置对应的SRS配置信息,终端在需要对应SIB1传输时,需要发送对应的SIB1/SSB请求信息。
在此场景下,小区2可能需要终端在获取SIB1之前获取对应的SRS配置信息。据此,终端可能需要基于小区2对应的SSB确定SRS配置信息,具体配置信息与实施场景三的图样类似,在此不再赘述。
在此场景下,SRS配置信息需要通过预定义方式确定,具体配置信息见实施例1和实施例2,在此不再赘述。
步骤2:终端确定小区2处于SSB和/或SIB1关闭状态。状态确定可以基于信令配置或预定义方式确定。
示例性地,终端通过显示信令确定SSB和/或SIB1的开启或关闭。
示例性地,终端基于预定义方式确定SSB和/或SIB1的开启或关闭。
示例性地,终端在第一时间窗内尝试接收SSB和/或SIB1,在终端成功接收SSB和/或SIB1后,终端确定处于SSB和/或SIB1的开启状态。
示例性地,终端在第一时间窗内尝试接收SSB和/或SIB1,并没有接收到对应的SSB/SIB信号,终端确定处于SSB和/或SIB1的关闭状态。
在SSB的开启状态下,网络设备周期性发送SSB。
在SSB的关闭状态下,网络设备不会周期性发送SSB。
在SIB1的关闭状态下,网络设备不会周期性发送SIB1。
在SIB1的开启状态下,网络设备会周期性发送SIB1。
第一时间窗基于信令配置或预定义方式确定,具体包括以下一种或多种:
第一时间窗起始位置基于如下方式确定:
终端上次接收SSB和/或SIB1对应时间单元,和/或,终端上次盲检SIB1对应DCI(SI-RNTI加扰的DCI 1_0)对应的时间单元;
第一时间窗持续长度基于如下方式确定:
M个时间单元,时间单元可以为帧、子帧、时隙、符号;
M个SSB传输周期,或者,M个SI-RNTI加扰的DCI 1_0的盲检周期;
N/M基于预定义或信令指示方式确定,示例性地,N等于2,M等于2。
步骤3:终端确定SRS配置信息,并发送对应的SRS信令请求SSB和/或SIB1传输。
步骤4-a:基站接收SRS,并确定SRS信令为请求SSB/SIB传输的信令。
SRS主要用于上行信道探测,例如,对应于波束管理(beamManagement)、基于码本(codebook)的测量、基于非码本(nonCodebook)的测量、天线切换(antennaSwitching)中的一种,可以称为第一SRS。
在本公开实施例场景中,针对SRS,引入了新的功能,即,SSB和/或SIB1请求信息的功能,可以称为第二SRS。
为区分上述两种功能,基站可以基于如下方式区分:
基于时频域资源区分,为第一SRS和第二SRS配置不同的时频域资源,基站基于不同的时频域资源,区分不同的SRS。
基于SRS序列区分,为第一SRS和第二SRS配置不同的SRS序列,基站基于不同的SRS序列,区分不同的SRS。
基于SRS对应的功能区分,为第一SRS和第二SRS配置不同的功能,从而达到区分SRS的目的。从终端的角度,终端也基于上述方式区分第一SRS和第二SRS,具体方式与基站类似,在此不再赘述。
步骤4-b:基站接收SRS,并确定是否传输对应的SSB和/或SIB1。
基站接收上述信号请求后,可以选择传输对应的SSB和/或SIB1。或者,基站接收上述信号请求后,可以选择继续不传输对应的SSB和/或SIB1。
步骤5:终端在发送对应的SSB和/或SIB1请求信息后,开始尝试接收对应的SSB和/或SIB1。
示例性地,终端在第一时间窗内尝试接收SSB和/或SIB1,在终端成功接收SSB和/或SIB1后,终端不再发送参考信号。
示例性地,终端在第一时间窗内尝试接收SSB和/或SIB1,并没有接收到对应的SSB/SIB信号,此时,终端发送参考信号。
示例性地,终端在第一时间窗内尝试接收SSB和/或SIB1,并没有接收到对应的SSB/SIB信号,此时,终端放弃SSB和/或SIB1接收。
示例性地,终端基于SSB配置周期或SIB1对应的配置周期尝试接收,在连续尝试N个周期后,若终端没有成功接收到对应的SSB和/或SIB1,终端放弃SSB和/或SIB1接收;或在终端有需求时,发送对应的参考信号。
第一时间窗基于信令配置或预定义方式确定,具体包括以下一种或多种:
第一时间窗起始位置基于如下方式确定:
终端发送参考信号所在时间单元;
终端发送参考信号后的下一个SSB传输周期,和/或,发送参考信号后的第一个SIB对应的DCI盲检周期;
终端上次接收SSB和/或SIB1对应时间单元,和/或,终端上次盲检SIB1对应DCI(SI-RNTI加扰的DCI 1_0)对应的时间单元;
第一时间窗持续长度基于如下方式确定:
M个时间单元,该时间单元可以为帧、子帧、时隙、符号;
M个SSB传输周期,或者,M个SI-RNTI加扰的DCI 1_0的盲检周期。
N/M基于预定义或信令指示方式确定,示例性地,N等于2,M等于2。
述为本公开实施例方案的具体实施流程。
实施例1:参考信号可为SRS,终端基于预定义或信令指示的方式确定传输参考信号的时频域资源以及对应的参考信号序列,并发送对应的参考信号。
