- UE2 measures CSI-RS1, obtains resources at time T1+3, and feeds back the measurement result of CSI-RS1 to UE1;
- UE1 sends CSI-RS2 at T2 and waits for UE2 to feedback;
- UE2 measures CSI-RS2, but within the window [T2, T2+4] does not obtain resources, does not feed back to UE1, and discards the measurement result;
- UE1 does not receive feedback until T2+4, so it no longer waits for feedback from UE2, and sends CSI-RS3 to UE2 at the subsequent time T3;
- the above is only an example with a fixed window length of 4 slots.
- the length can also be dynamically changed. For example, if the CBR measurement shows that the link is congested, a longer window is used (because it may be difficult for the UE to reserve Send resources), if the link is idle, then use a shorter window.

下面分别对反馈窗口、标识信息、反馈资源和HARQ反馈信息进行详细说明:
可选的,在所述关联信息包括所述反馈窗口的情况下,所述第一终端发送的测量信号关联至少一个反馈窗口,所述测量结果关联的测量信号,包括:
所述测量结果的反馈窗口关联的测量信号。
该实施方式中,第一终端发送测量信号时,每个测量信号关联有至少一个反馈窗口,例如:对于测量信号,关联至少一个反馈窗口,窗口长度为N,用于接收测量反馈。这样,当接收到测量结果,就可以通过测量结果所在反馈窗口,确定其关联的测量信号。
在一种实现方式中,上述第一终端发送的测量信号关联至少一个反馈窗口可以包括:
所述第一终端发送的测量信号后,启动的至少一个反馈窗口,其中,所述至少一个反馈窗口的属性可以与如下至少一项参数相关:
终端处理能力、资源池配置、带宽部分(Band Width Part,BWP)的参数集(numerology)、BWP的子载波间隔(subcarrier spacing,SCS)、载波的numerology、载波的SCS、小区的numerology和小区的SCS。
其中,上述属性可以包括反馈窗口的起始时间和窗口长度中的至少一项。
上述终端处理能力可以是上述第一终端的处理能力或者第二终端的处理能力,上述资源池配置可以是上述sidelink的资源池配置,上述BWP、载波和小区可以是上述sidelink的BWP、载波和小区。
上述属性与上述至少一项参数相关可以是,上述属性由上述至少一项确定,例如:窗口长度N不小于终端的处理时延,或者,窗口的起始时间T为测量信号发送时间+终端的处理时延,或者,不同BWP、载波或资源池配置,或不同的numerology可以有不同的处理时延或窗口长度,或者不同终端类型可以有不同的处理时延或窗口长度。
需要说明的是,上述参数与属性的关系可以预先配置,或者控制节点指 示等。另外,一个参数可以是与一个属性值对应的,或者一个参数可以是与一个属性值范围或者属性参考值对应。
在一种实现方式中,所述至少一个反馈窗口的属性固定不变,或者,所述至少一个反馈窗口的属性根据服务质量(Quality of Service,QoS)需求、信道状态或链路拥塞情况动态调整。
其中,上述QoS需求可以是优先级、时延、可靠度要求等等,而上述链路拥塞情况可以是信道繁忙比率(channel busy ratio,CBR)或信道占用比率(Channel occupancy ratio,CR)测量结果等等。
另外,上述反馈窗口的属性固定不变可以是,针对一个参数对应的属性固定不变,例如:一个参数对应一个属性值;而上述动态调整可以是,针对一个参数对应的属性可以动态调整,例如:一个参数对应一个属性值范围或者属性参考值,可以在该范围内动态调整,或者基于该属性参考值动态调整。
例如:对于某个参数(资源池配置或载波或numerology等等),反馈窗口的窗口长度可以是固定长度的,例如,由协议定义或网络配置确定;或可变长度,如根据QoS需求或信道状态或链路拥塞情况动态调整窗长(例如,当链路拥塞时,使用更长的窗口)。
需要说明的是,本公开的一些实施例中,反馈窗口的时间单位粒度可以是无线帧、子帧、时隙(slot)、子时隙(sub-slot)、符号(symbol)等等,窗口长度可以是基于***时间(system frame number,SFN),sidelink时间(direct frame number,DFN),或资源池的有效时域信息等等。
另外,反馈窗口可以是由控制节点配置,或者在发送终端和接收终端间直接协商,或协议定义或预配置等等。
在一种实现方式中,若所述至少一个反馈窗口超时,且未获取到测量结果,则所述第一终端不再等待所述至少一个反馈窗口关联的测量信号的测量结果。
这样可以实现,在反馈窗口内未接收到测量结果,则确定该测量信号的反馈结果反馈失败,从而不再等待,以避免第一终端继续等待浪费资源。
例如:第一终端发送测量信号后,在T时刻启动反馈窗口;
其中,在T+N的窗口内等待接收终端的测量反馈,且可以是启动长度为 N的定时器;
当满足以下任一条件时,第一终端认为窗口时间已过:
如果第一终端在窗口内收到至少一个有效的测量反馈,则认为窗口时间已过,此时可以停止定时器;
如果超过窗口时间,第一终端仍然没有收到测量反馈,则认为窗口时间已过,此时可以确认定时器发生超时。
如果超过窗口时间,则不再等待第一终端关联该测量信号的反馈。
进一步的,在上述测量信号的至少一个反馈窗口内,第一终端不发送第二个测量信号。
而第二终端在收到测量信号后,可以在窗口内(T+N时刻内)反馈测量结果。例如:可以启动长度为N的定时器,并在发送反馈后停止该定时器,如果第二终端在该窗口内无法反馈(例如,由于没能获取sidelink资源进行传输,或由于半双工限制无法发送反馈,或反馈发送失败,或功率受限无法发送反馈,等等),则第二终端可以丢弃该测量结果,不在窗口外反馈。另外,如果定时器超时仍然没有发送成功,也可以丢弃该测量结果。
如果第二终端在窗口内接收到第一终端发送的新的测量信号,第二终端可以放弃之前收到的测量信号与测量结果,重新确定窗口起始时间,并在窗口内反馈关联新的测量信号的测量结果。例如:可以重启长度为N的定时器。
需要说明的是,本公开的一些实施例中,发送测量信号的资源,可以是第一终端通过资源感知(sensing)、预留获取的,也可以是控制节点分配的。而发送测量反馈的资源,可以是第二终端通过资源感知(sensing)、预留获取的,也可以是控制节点分配的。
下面以第一终端为UE1,第二终端为UE2,测量信号为CSI-RS进行举例说明,包括以下内容:
1、UE1与UE2进行sidelink传输,UE1配置了CSI-RS测量信号给UE2测量,反馈窗口长度为4个slot;
2、UE1在T1时刻发送CSI-RS1,等待UE2反馈;
3、UE2对CSI-RS1进行测量,在T1+3时刻获取到资源,向UE1反馈CSI-RS1的测量结果;
4、UE1在T2时刻发送CSI-RS2,等待UE2反馈;
5、UE2对CSI-RS2进行测量,但在窗口内[T2,T2+4]没有获取到资源,没有向UE1反馈,并丢弃该测量结果;
6、UE1到T2+4为止没有收到反馈,从而不再等待UE2的反馈,在后续T3时刻发送CSI-RS3给UE2;
其中,上述仅是以窗口长度固定为4个slot进行举例说明,该长度也可以动态变化,例如,如果CBR测量显示链路拥塞,则使用较长的窗口(因为此时UE可能难以预留到发送资源),如果链路较空闲,则则使用较短的窗口。
需要说明的是,通过反馈窗口的方式,可以达到如下效果:
对于每一个收到的测量结果,第一终端都清楚它关联的CSI-RS;
反馈开销低,测量结果反馈只需要携带测量结果本身,不需要任何其他信息(例如,关联的标识信息等等);
控制信令开销低,指示测量信号的控制信令(例如,SCI)不需要携带额外指示(例如,SCI中的分配索引等)。
可选的,在所述关联信息包括所述标识信息的情况下:
所述标识信息用于关联测量信号,所述测量结果关联的测量信号包括:所述标识信息关联的测量信号;或者
所述标识信息用于关联测量信号的参数信息,所述测量结果关联的测量信号包括:所述标识信息关联的参数信息对应的测量信号。
其中,上述标识信息用于关联测量信号可以是,上述标识信息用于识别出测量结果关联的测量信号。例如:标识信息用于关联一个特定的测量信号,从而第一终端可以通过该标识信息得知测量结果与哪个测量信号关联,以及第二终端是否漏检了哪个测量信号。
而上述标识信息用于关联测量信号的参数信息可以是,上述标识信息用于识别出测量结果关联的测量信号的参数信息,从而通过该参数信息可以确定具体的测量信号。
其中,上述参数信息可以包括如下至少一项:
时域信息、频域信息、码域信息、标识、反馈窗口信息、控制信令信息和相对于所述测量结果的传输时刻的时间间隔。
其中,上述时域信息可以是测量信号的子帧、slot/sub-slot或symbol编号等等,而上述频域信息可以是测量信号的起始物理资源模块(Physical Resource Block,PRB)或子信道索引(sub-channel index)等等,上述码域信息可以是测量信号的序列或加扰序列或正交掩码(orthogonal cover code,OCC)序列等等,上述反馈窗口信息可以是测量信号关联的反馈窗口的信息,如起始时域信息、窗口长度等等,或控制信令信息可以是SCI中的分配索引或HARQ进程号或SCI的资源位置或index等等。
该实施方式中,可以通过上述至少一项参数确定测量结果关联的测量信号。
另外,为了减少开销,上述标识信息可以是上述至少一项参数信息经过特定运算的结果,例如:对slot index或sub-channel index求模运算(MOD)的结果,例如:上述标识信息=slot index mod K,K是定义/(预)配置的。
可选的,在所述关联信息包括所述标识信息的情况下,所述获取测量结果,包括:
获取测量结果消息,所述测量结果消息携带有一个或者多个测量结果,以及每个测量结果的标识信息。
其中,所述测量结果消息的载荷(Payload)可以携带一个或者多个测量结果,以及每个测量结果的标识信息,且所述Payload为固定大小或者可变大小,其中,在所述Payload为可变大小的情况下,所述测量结果消息还携带有测量结果的数量指示。
这样,可以实现如果第二终端反馈测量结果时,一次反馈中可以携带多个测量结果,则可以用以下方式设计测量结果的payload:
一、固定大小的Payload,不管第二终端实际需要反馈的测量结果的数量,Payload可以分成N个部分,每个部分包含一个或多个测量结果与(可选的)该测量结果关联的标识信息。另外,可以按照测量结果的时间顺序或频域顺序或类型或分组等排列构造,且对于没有对应测量结果的部分,第二终端可以填充一个特殊值(例如,无效值);
二、可变大小的payload,可以是媒体接入控制层控制单元(Media Access Control Control Element,MAC CE)或携带(piggyback)在PSSCH中;如 果是MAC CE,MAC CE包含有效的反馈测量结果的数量指示,以及每个测量结果与(可选的)该测量结果关联的标识信息;如果piggyback在PSSCH中,则反馈中包含多个测量结果与(可选的)该测量结果关联的标识信息;或者,反馈中包含一个固定大小部分,指示反馈结果的数量,以及一个可变大小的部分,包含每个测量结果与(可选的)该测量结果关联的标识信息。
例如:在上述步骤201中第一终端可以获取到一个或者多个测量结果,例如:第一终端在发送测量信号后,等待第二终端的测量反馈,且在收到有效测量反馈前,第一终端仍然可以发送新的测量信号;第二终端在收到测量信号后,向第一终端反馈测量结果,一次反馈中可以携带一个或多个测量结果,每个结果关联一个或一组标识信息(例如,ID)。
进一步的,如果有测量结果关联的标识信息相同,第二终端可以只反馈其中一个或部分结果。例如:可以按优先级排序选择,优先级可以是关联的测量信号的时间顺序(例如,越早或越晚发送的测量信号,优先级越高等等),或调度指示(例如,SCI)中指示的QoS信息,或测量信号的资源分配属性(例如,测量信号的带宽越大,则优先级越高)。
或者,第二终端也可以合并该组测量信号的测量结果并反馈,例如,对该组内的多个测量信号进行测量,将结果经过平均或滤波等操作得到一个合并的测量结果并反馈。
进一步的,有所述参数信息重叠的多个测量信号的发送时间存在时间间隔,这样在一些场景中,有效地避免反馈错误。其中,上述参数信息重叠可以是上述至少一个项参数信息中的部分或者全部重叠,例如:如果两个测量信号间有部分或者全部属性重叠(例如,测量信号包含了相同的带宽、PRB、sub-channel或起始频域位置等),则第二终端可以预期(或认为、假设)这两个测量信号的发送至少有一个时间间隔,即一个第一终端在一个反馈窗口内不会发送相同标识的测量信号给同一个第二终端。
下面以第一终端为UE1,第二终端为UE2,测量信号为CSI-RS进行举例说明,包括以下内容:
1、UE1与UE2进行sidelink传输,UE1配置了CSI-RS测量信号给UE2测量;
2、UE1在T1、T2时刻分别发送CSI-RS1、CSI-RS2给UE2,如图3所示;
3、UE2在T3、T4时刻获取到资源,向UE1反馈CSI-RS1、CSI-RS2的测量结果,如图3所示;
4、每个反馈结果中携带了测量结果与关联的CSI-RS的标识信息,例如,发送CSI-RS的slot MOD P,或发送CSI-RS的起始sub-channel index MOD Q。P、Q是预定义的常量。
需要说明的是,通过标识信息的方式,可以达到如下效果:
对于每一个收到的测量结果反馈,根据反馈中的标识信息,第一终端都清楚该测量结果关联的测量信号。不管是第二终端漏检了某一个CSI-RS,还是第一终端没收到某一个测量反馈,第一终端都能够发现具体是哪个传输失败了;
测量信号发送延迟低,可以连续发送多个测量信号用于测量,有利于提高测量精度;
控制信令开销低,指示测量信号的控制信令(例如,SCI)不需要携带额外指示(例如,SCI中的分配索引等)。
下面再以第一终端为UE1,第二终端为UE2,测量信号为CSI-RS进行举例说明,包括以下内容:
1、UE1与UE2进行sidelink传输,UE1配置了CSI-RS测量信号给UE2测量;
2、UE1在T1、T2时刻分别发送CSI-RS1、CSI-RS2给UE2,如图4所示;
3.UE2在T3时刻获取到资源,向UE1同时反馈CSI-RS1、CSI-RS2的测量结果,如图4所示;
其中,反馈结果中携带了反馈的测量结果的数量(=2),以及每个测量结果与关联的CSI-RS的标识信息;
或者,还有一种情况是反馈结果中携带了一个测量结果,该测量结果是UE2合并了CSI-RS1与CSI-RS2的测量结果,从而获得更好更精确的结果;例如,CSI-RS1占用了子信道0-9,CSI-RS2占用了子信道10-19,UE2反 馈的宽带(wideband)测量结果由于测量了子信道0-19,因而比单独基于CSI-RS1或CSI-RS2更为准确。
需要说明的是,通过标识信息的方式,可以达到如下效果:
对于每一个收到的测量结果反馈,根据反馈中的标识信息,第一终端都清楚该测量结果关联的测量结果。如果第二终端漏检了某一个测量信号,第一终端可以发现具体是哪个传输丢失了;
测量信号发送延迟低,可以连续发送多个测量信号用于测量,有利于提高测量精度;
控制信令开销低,指示测量信号的控制信令(例如,SCI)不需要携带额外指示(例如,SCI中的分配索引等)。
可选的,在所述关联信息包括所述反馈资源的情况下,所述第一终端发送测量信号时分配有测量结果的反馈资源,所述测量结果关联的测量信号,包括:
所述测量结果的反馈资源对应的测量信号。
该实施方式中,可以是第一终端在发送测量信号时,为该测量信号分配为测量结果的反馈资源,从而第一终端从该资源获取第二终端的测量结果,并通过测量结果使用的反馈资源,确定测量结果关联的测量信号。例如:第一终端发送测量信号时,为第二终端分配资源用于发送测量反馈,第一终端可以是在控制信令(例如,SCI,MAC CE,或RRC)中指示测量信号,同时指示(包括预留、分配)了sidelink资源给第二终端。
另外,指示测量信号与指示资源可以是相同或不同的控制信令,例如SCI指示测量信号,而MAC CE指示sidelink资源。且第二终端的标识可以携带在指示资源预留的信令中,例如MAC CE同时指示sidelink资源和在该资源上传输反馈信息的终端。
进一步的,上述反馈资源可以用于发送数据,所述测量结果携带在所述数据反馈,这样可以节约资源。
例如:第二终端使用该资源发送数据(可以是给第一终端或其他终端,可以是单播或组播等等),并同时使用数据携带测量反馈。且一次反馈中可以携带一个或多个测量结果,当携带多个结果时,每个结果可以关联一个或一 组标识信息,具体可以参见上述标识信息的实施方式的相应说明,此处不作赘述。
需要说明的是,不作限定反馈资源可以用于发送数据,例如:上述反馈资源可以是仅用于反馈测量结果,而不用于发送数据。
下面以第一终端为UE1,第二终端为UE2,测量信号为CSI-RS进行举例说明,包括以下内容:
1、UE1与UE2进行sidelink传输,UE1配置了CSI-RS测量信号给UE2测量;
2、UE1在T1时刻给UE2发送PSSCH,在调度该PSSCH的SCI中指示有CSI-RS发送,同时,该SCI预留了后续T2时刻的资源给UE2;
3、UE2收到该SCI,对CSI-RS进行测量,并在T2时刻在SCI预留的资源反馈测量结果。
需要说明的是,通过反馈资源的方式,可以达到如下效果:
对于每一个收到的测量结果反馈,第一终端都清楚该测量结果关联的测量信号。如果第二终端漏检了T1时刻的传输,第一终端在T2时刻预留的资源不会收到第二终端的数据,因此可以发现传输丢失了;
测量信号发送延迟低,可以连续发送多个测量信号用于测量,有利于提高测量精度;
反馈开销低。
可选的,在所述关联信息包括所述HARQ反馈信息的情况下,所述第一终端发送的数据携带测量信号,所述测量结果关联的测量信号,包括:
所述测量结果的HARQ反馈信息对应的数据所携带的测量信号。
其中,上述HARQ反馈信息是对第一终端发送的数据的HARQ反馈信息,由于第一终端发送的数据携带有测量信号,且反馈信息为与所述测量结果一起发送的HARQ反馈信息,这样第一终端接收到测量结果和HARQ反馈信息,就可以确定对应的数据,进而确定对应的测量信号。
例如:第一终端发送物理旁链路共享信道(Physical Sidelink Shared Channel,PSSCH)数据,并携带测量信号给第二终端,且第一终端可以在控制信令(例如,SCI,MAC CE,或RRC)中指示PSSCH资源以及测量信号。
当第二终端接收到该PSSCH数据,并解调PSSCH数据,测量PSSCH关联的测量信号,之后,第二终端同时发送该PSSCH数据的HARQ反馈以及关联该PSSCH数据的测量信号的测量反馈。其中,第二终端可以使用HARQ反馈的物理旁链路反馈信道(Physical Sidelink Feedback Channel,PSFCH)资源进行发送,或携带在PSSCH资源中发送。
另外,还可以是预先配置多个候选的PSFCH,第二终端选择其中一个PSFCH反馈HARQ反馈信息,通过反馈HARQ反馈信息的PSFCH来表示上述测量结果,即第一终端通过接收HARQ反馈信息,以获取到上述测量结果。例如,预先配置了PSFCH-0与PSFCH-1,第二终端反馈测量结果时,如果反馈测量结果0,选择PSFCH-0发送HARQ反馈信息,以通过PSFCH-0来表示测量结果0,否则,选择PSFCH-1发送,以通过PSFCH-1来表示测量结果1。
需要说明的是,上述测量结果0和测量结果1可以是一种测量结果索引,第一终端通过该索引可以确定具体的测量结果内容;当然,也可以是测量结果具体值为0或者为1,且上述测量结果0和1仅是举例说明,例如:可以配置N个候选的PSFCH,这样表示N个测量结果。
同样,该实施方式中,一次反馈中可以携带一个或多个测量结果,当携带多个结果时,每个结果可以关联一个或一组标识信息,具体可以参见上述标识信息的实施方式的相应说明,此处不作赘述。
第一终端接收HARQ反馈以及测量反馈,根据关联的PSSCH数据传输可以确定该测量反馈关联的测量信号。
下面以第一终端为UE1,第二终端为UE2,测量信号为CSI-RS进行举例说明,包括以下内容:
1、UE1与UE2进行sidelink传输,UE1配置了CSI-RS测量信号给UE2测量。
2、UE1在T1时刻给UE2发送PSSCH,在调度该PSSCH的SCI中指示有CSI-RS发送
3、UE2收到该SCI,对PSSCH进行解调,并对CSI-RS进行测量
4.UE2在T2时刻,在用于HARQ反馈的PSFCH信道中一起携带测 量结果。
需要说明的是,通过HARQ反馈信息的方式,可以达到如下效果:
对于每一个收到的测量结果反馈,第一终端都清楚该测量结果关联的测量信号。如果第二终端漏检了T1时刻的传输,第一终端在T2时刻不会收到第二终端的反馈,因此可以发现传输丢失了;
测量信号发送延迟低,可以连续发送多个测量信号用于测量,有利于提高测量精度;
反馈开销低。
需要说明的是,上述反馈窗口、标识信息、反馈资源和HARQ反馈信息的实施方式是可以相互结合实现的,例如:以反馈窗口和标识信息相结合为例:
第一终端发送的测量信号关联一个反馈窗口;
且第一终端在收到有效测量反馈前,仍然可以发送新的测量信号;
第二终端在收到测量信号后,向第一终端反馈测量结果;
如果第二终端在窗口内接收到第一终端发送多个测量信号,则第二终端可以放弃部分测量结果,或反馈合并的测量,例如:如果两个信号的标识相同,可以放弃,或者取平均信号测量值。或者,如果第二终端在窗口内接收到第一终端发送多个测量信号,第二终端可以一次反馈中可以携带一个或多个测量结果,例如,测量信号的标识不同;另外,每个测量结果可以关联一个标识信息。
且如果测量结果超过反馈窗口,则第二终端可以丢弃该测量结果,不向第一终端反馈该结果。
需要说明的是,本公开的一些实施例中,一次测量结果(或者称作一个测量结果)可以是对一个或多个测量信号的测量结果,也就是说,一个测量结果可以关联一个或者多个测量信号。当测量结果关联多个测量信号时,第二终端可以在反馈窗口时间内测量多个测量信号来获得一个测量结果。从而有利于提高宽带(wideband)测量的精度。
另外,测量结果的反馈可以是携带在PSSCH中,或在PSFCH信道中传输,或者可以通过第二终端选择并使用的PSFCH来表示测量结果,具体可以 参见上述预先配置多个候选的PSFCH的相应说明,本公开并不作限定反馈测量结果的具体实现方式。
本公开的一些实施例中提供的sidelink测量结果获取方法,可以用于sidelink下终端之间反馈测量结果,可以明确测量信号与测量结果之间的关联关系,从而解决了终端间由于无法确定测量信号与测量结果之间的关联关系,导致链路传输调整出错以及后续数据传输失败的问题。
具体可以通过以下一个或多个方法确定测量信号与测量结果之间的关联关系:
1、对于测量信号定义反馈窗口,第二终端只在反馈窗口内反馈测量结果;
2、测量反馈中包含一个或多个测量报告,每个测量报告包含测量结果以及该结果关联的测量信号的标识信息(例如,CSI-RS的起始PRB/sub-channel index);
3、第一终端在发送测量信号时,为第二终端预留资源用于反馈测量结果;
4、第二终端在发送数据HARQ反馈时,把测量结果与HARQ反馈复用在一起发送。
请参见图5,图5是本公开的一些实施例提供的一种sidelink测量结果发送方法的流程图,该方法应用于第二终端,如图5所示,包括以下步骤:
