图1示出本申请实施例可应用的一种无线通信系统的结构图。无线通信系统包括远端终端11、网络侧设备12和中继终端13。其中,远端终端11也可以称作终端设备或者用户终端(User Equipment,UE),远端终端11可以是手机、平板电脑(Tablet Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant,PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer,UMPC)、移 动上网装置(Mobile Internet Device,MID)、可穿戴式设备(Wearable Device)或车载设备(Vehicle User Equipment,VUE)、行人终端(Pedestrian User Equipment,PUE)等终端侧设备,可穿戴式设备包括:手环、耳机、眼镜等。需要说明的是,在本申请实施例并不限定远端终端11的具体类型。网络侧设备12可以是基站或核心网,其中,基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station,BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set,BSS)、扩展服务集(Extended Service Set,ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点、发送接收点(Transmitting Receiving Point,TRP)或所述领域中其他某个合适的术语,只要达到相同的技术效果,所述基站不限于特定技术词汇,需要说明的是,在本申请实施例中仅以NR系统中的基站为例,但是并不限定基站的具体类型。
下面结合附图,通过具体的实施例及其应用场景对本申请实施例提供的推荐比特率确定方法进行详细地说明。
请参见图2,图2是本申请实施例提供的一种推荐比特率确定方法的流程图,该推荐比特率确定方法包括:
步骤201、第一中继终端执行第一操作,所述第一操作包括如下至少一项:
接收第一目标设备发送的第一推荐比特率信息;
向第二目标设备发送第二推荐比特率信息;
其中,所述第一推荐比特率信息包括所述第一目标设备与所述第一中继终端之间的推荐比特率;
所述第二推荐比特率信息包括所述第一中继终端与所述第二目标设备之间的推荐比特率。
具体的,第一中继终端也可称为relay UE,第一中继终端可以接收第一目标设备发送的第一推荐比特率信息,也可以向第二目标设备发送第二推荐比特率信息,还可以接收第一目标设备发送的第一推荐比特率信息之后,向第二目标设备发送第二推荐比特率信息。第一目标设备可为远端终端(也可 称为remote UE)、网络侧设备(例如,基站)或第二中继终端,第二目标设备也可为远端终端、网络侧设备或第二中继终端,也就是说,第一中继终端可以与远端终端、网络侧设备或第二中继终端进行推荐比特率信息的发送和接收。
第一中继终端可位于网络侧设备和远端终端之间,即网络侧设备和远端终端不直接进行通信,而是通过第一中继终端进行通信。例如,在层3(Layer 3,L3)的用户终端到网络(UE-to-Network,U2N)架构中,远端终端对于基站来说是不可见的,relay UE将remote UE的传输需求当成自己的需求,向基站进行请求,基站获知的都是relay UE的传输需求。
第一中继终端也可位于第一远端终端和其他远端终端之间,即第一远端终端和其他远端终端不直接进行通信,而是通过第一中继终端进行通信。例如,在L3的用户终端到用户终端(UE-to-UE,U2U)架构中,与第一远端终端通信的最终端为其他远端终端,在第一远端终端和其他远端终端之间,设置有第一中继终端,或者,设置有第一中继终端和其他中继终端。
在U2N架构或U2U架构中,网络侧设备与远端终端之间,或者远端终端(即第一远端终端)与其他远端终端之间,均通过第一中继终端进行通信,第一中继终端接收的第一推荐比特率信息,和/或,第一中继终端发送第二推荐比特率信息,使得第一中继终端在进行推荐比特率交互及传递时,远端终端业务源编码可更好的适应链路情况,提升传输的效率,保障了远端终端的业务体验和系统效率。
可选地,在所述接收第一目标设备发送的第一推荐比特率信息的步骤之前,第一中继终端还可以先确定当前是否处于中继通信连接状态,和/或,确定所述第一目标设备。
可选地,在所述向第二目标设备发送第二推荐比特率信息的步骤之前,第一中继终端可以先确定待发送的第二推荐比特率信息,和/或,确定所述第二目标设备。
在本申请一个实施例中,所述第一目标设备包括网络侧设备,所述第一推荐比特率信息包括所述网络侧设备与所述第一中继终端之间的Uu链路的推荐比特率。
在relay UE的Uu接口上,基站可以向relay UE发送携带第一推荐比特率信息的媒体访问控制(Media Access Control,MAC)控制元素(Control Element,CE)信令,用于发送上行和/或下行的推荐比特率,即第一推荐比特率信息包括网络侧设备与第一中继终端之间的Uu链路的推荐比特率,第一推荐比特率信息通过所述第一中继终端的Uu接口获取。
在本申请一个实施例中,所述第二目标设备包括网络侧设备,所述第二推荐比特率信息包括所述第一中继终端与所述网络侧设备之间的Uu链路的推荐比特率。relay UE也可以通过Uu链路向基站发送上行和/或下行的推荐比特率请求,即第二推荐比特率信息包括第一中继终端与网络侧设备之间的Uu链路的推荐比特率。
在本申请一个实施例中,所述第二目标设备包括网络侧设备,所述第二推荐比特率信息包括的推荐比特率根据如下方式确定:
所述第一中继终端接收的所述至少一个远端终端发送的推荐比特率。
上述中,在所述至少一个远端终端为一个远端终端的情况下,所述至少一个远端终端发送的推荐比特率可理解为该一个远端终端发送的推荐比特率;在所述至少一个远端终端包括两个以及多个远端终端的情况下,所述至少一个远端终端发送的推荐比特率可理解为该至少一个远端终端中各远端终端发送的推荐比特率。
第一中继终端可以将至少一个远端终端中各个终端发送的推荐比特率之和发送给网络侧设备,第一中继终端也可以根据获取的与所述网络侧设备之间的Uu链路质量或容量,确定Uu链路的推荐比特率,并比较推荐比特率之和与Uu链路的推荐比特率的大小,将值小的推荐比特率确定为第二推荐比特率信息包括的推荐比特率,并将第二推荐比特率信息发送给网络侧设备。
另外,所述第二目标设备包括网络侧设备,所述第二推荐比特率信息包括的推荐比特率还可以根据如下其中一种方式确定:
所述第一中继终端获取的与所述网络侧设备之间的Uu链路质量或容量;
所述第一中继终端获取的与至少一个远端终端之间的PC5链路质量或容量。
具体的,在所述第一中继终端获取到与所述至少一个远端终端之间的 PC5链路质量或容量的情况下,根据所述第一中继终端与每个远端终端之间的PC5链路质量或容量,确定各远端终端对应的推荐比特率,并将各远端终端对应的推荐比特率之和确定为所述第二推荐比特率信息包括的推荐比特率。
在所述第一中继终端获取到与所述网络侧设备之间的Uu链路质量或容量,且所述第一中继终端获取到与至少一个远端终端之间的PC5链路质量或容量的情况下,根据所述第一中继终端与每个远端终端之间的PC5链路质量或容量,确定各远端终端对应的推荐比特率;
若各远端终端对应的推荐比特率之和大于根据Uu链路质量或容量确定的推荐比特率,则将根据Uu链路质量或容量确定的推荐比特率确定为所述第二推荐比特率信息包括的推荐比特率;
若各远端终端对应的推荐比特率之和小于根据Uu链路质量或容量确定的推荐比特率,则将各远端终端对应的推荐比特率之和确定为所述第二推荐比特率信息包括的推荐比特率。
也就是说,relay UE如果发现自己的链路情况不好,不能容纳现有的业务源速率,可以向基站建议推荐比特率。例如,relay UE可以测量Uu链路(relay UE与基站之间的通信链路)和PC5链路(relay UE与各remote UE之间的通信链路),综合考虑Uu链路和PC5链路的质量和容量,以较小容量来决定推荐比特率。
例如,relay UE测量的Uu链路,确定推荐比特率,直接上报给基站供参考;或者,relay UE测量PC5链路,即,relay UE与每个remote UE之间的PC5链路,形成针对每个remote UE的推荐比特率,再将可复用到一个Uu逻辑信道标识(Logical Channel Identifier,LCID)的不同remote UE的推荐比特率加和,形成Uu LCID级别的推荐比特率,上报给基站。
在本申请一个实施例中,所述第二目标设备包括网络侧设备;
在第一中继终端向第二目标设备发送第二推荐比特率信息之后,所述方法还包括:
启动禁止定时器,所述禁止定时器用于禁止所述第一中继终端向所述网络侧设备发送推荐比特率信息。
例如,relay UE向基站上报一次Uu推荐比特率之后,会启动禁止定时器, 在禁止定时器运行期间不允许再次上报,直至定时器超时,再进行上报。
在U2N场景中,网络侧设备是控制方,relay UE或remote UE是请求方。而在U2U场景中,通信的两端为relay UE和remote UE,或者,一个remote UE与另一个remote UE,或者一个relay UE与另一个relay UE,第一推荐比特率信息或第二推荐比特率信息中还需要包括指示第一中继终端或远端终端是请求方或控制方的指示信息。请求方也可称为建议方或接收方,控制方也可称为决策方或发送方。
例如,TX UE(即发送UE,发送UE可为relay UE或remote UE)为真正执行业务源速率调整,可以由TX UE作为决策方,决定这个方向的比特率,而RX UE由于是接收方,相对被动,它可以根据自己的测量情况给予建议。
在发送终端1(Transport UE1,TX UE1)(UE1为控制方)到接收终端2(Receive UE2,RX UE2)(UE2为请求方)的方向,TX UE1给出的推荐比特率是业务源编码真正执行的速率,而RX UE2给出的推荐比特率可以是这个方向的建议值;反之,在TX UE2(UE2为控制方)到RX UE1(UE1为请求方)的方向,TX UE2给出的推荐比特率是业务源编码真正执行的速率,而RX UE1给出的推荐比特率可以是这个方向的建议值。
U2U场景中,通信的两端任意一个UE都有权决定,也有权建议,在信令中携带指示信息自身是决定还是建议即可,便于对端遵照或者参考执行。
也就是说,所述第一目标设备包括远端终端;
所述第一推荐比特率信息包括:与所述远端终端和所述第一中继终端中至少一项相关联的目标对象的推荐比特率,以及指示信息;
和/或,
所述第二目标设备包括远端终端;
所述第二推荐比特率信息包括:与所述远端终端和所述第一中继终端中至少一项相关联的目标对象的推荐比特率,以及指示信息;
其中,所述指示信息用于指示所述远端终端或所述第一中继终端为控制方或请求方。
其中,所述指示信息包括如下至少一项:
用于指示控制方向的方向标识位,所述控制方向为所述远端终端向所述 第一中继终端的方向,或所述第一中继终端向所述远端终端的方向;
标识位,所述标识位用于指示所述远端终端和所述第一中继终端中的一者为控制方,和/或另一者为请求方。
具体的,为每个方向划分清晰的标识,例如UE1→UE2作为方向(direction)1,UE2→UE1作为direction2,在direction 1方向上,默认UE1决定,UE2建议,在direction 2上,默认UE2决定,UE1建议。direction 1和direction 2即为方向标识位,根据该方向的方向标识位可知UE1、UE2为控制方或请求方。
若控制UE1到UE2的信令方向,则bit置位为0,如果控制反方向,bit置位为1;bit即为方向标识位,根据该方向的方向标识位可知UE1、UE2为控制方或请求方。
远端终端或所述第一中继终端为控制方还是建议方,可以采取默认的规定,或者显式指示,例如,采用标识位进行指示。举例来说,通过1个比特位携带,若比特位为0表示控制方,比特位为1表示建议方。
所述目标对象包括如下至少一项:
PC5 LCID;
目的层二标识;
源层二标识;
PC5链路;
PC5优先级;
信道繁忙率(Channel Busy Ratio,CBR)区间。
由于U2U涉及到的是两个UE之间,例如,第一remote UE和relay UE之间,relay UE和第二remote UE之间,在进行推荐比特率交互时可以采用如下粒度:
使用PC5 LCID粒度:指推荐的推荐比特率是针对一个PC5 LCID进行控制或者请求,对于业务源端的UE(业务源端的UE可理解为remote UE)将根据该比特率设置一个逻辑信道的速率;
使用PC5独特的目的层二标识(即Destination L2 ID)粒度:指推荐的推荐比特率是针对一个特定的Destination L2 ID进行控制或者请求,对于业 务源端的UE将根据该比特率设置发往一个Destination L2 ID的速率;
使用PC5独特的源层二标识(Source L2 ID)以及Destination L2 ID粒度;指推荐的推荐比特率是针对一个特定的Source L2 ID以及Destination L2 ID进行控制或者请求,对于业务源端的UE将根据该比特率设置由特定Source L2 ID发往特定Destination L2 ID的速率;

使用PC5优先权粒度:指推荐的推荐比特率是针对一个特定的PC5优先权进行控制或者请求,对于业务源端的UE将根据该比特率设置特定PC5优先权发送速率;
使用信道繁忙率(Channel Busy Ratio,CBR)区间(Range)粒度;指推荐的推荐比特率是针对一个特定的CBR区间进行控制或者请求,对于业务源端的UE将根据该比特率设置位于特定CBR区间时的发送速率。
在本申请一个实施例中,所述第一推荐比特率信息包括至少一个承载标识,以及承载标识对应的第一推荐比特率。
第一中继终端在接收第一推荐比特率信息之后,可对第一推荐比特率进行拆分后发送。即,在一种实现方式中,所述至少一个承载标识为所述第一中继终端与第一目标设备之间的承载的承载标识;
相应的,在所述接收第一目标设备发送的第一推荐比特率信息之后,所述方法还包括:
所述第一中继终端根据所述至少一个承载标识,以及所述第一中继终端存储的第一映射表,确定下一跳对应的第一目标承载标识,所述第一映射表包括所述第一中继终端上一跳对应的承载标识与下一跳对应的承载标识之间的映射关系;
在所述第一目标承载标识包括第一标识和第二标识的情况下,所述第一中继终端对所述第一推荐比特率进行拆分,获得所述第一标识对应的推荐比特率,以及所述第二标识对应的推荐比特率;
所述第一中继终端在所述第一标识对应的承载上发送所述第一标识对应 的推荐比特率;
所述第一中继终端在所述第二标识对应的承载上发送所述第二标识对应的推荐比特率。
也就是说,在根据第一映射表确定第一中继终端的上一跳的承载标识对应多个下一跳的承载标识的情况下,可将从上一跳接收到的第一推荐比特率进行拆分,拆分成多个下一跳的承载对应的推荐比特率。承载标识可为LCID,无线链路控制(Radio Link Control,RLC)承载标识,或者资源块(Resource Block,RB)标识等。
例如,U2N架构中,控制一般为下行方向:gNB→relay UE(这两者之间为Uu LCID粒度)或者relay UE→remote UE(这两者之间为PC5 LCID粒度),控制的粒度是当前接口的LCID。gNB为relay UE的上一跳,remote UE为relay UE的下一跳。若根据第一映射表确定Uu LCID映射多个PC5 LCID,则relay UE按照速率组成进行等比划分,将从gNB接收的第一推荐比特率分割成多个PC5推荐比特率,然后将各PC5推荐比特率通过各PC5 LCID对应的承载进行发送。
第一标识和第二标识各自对应的承载为第一中继终端与其他UE(可以为remote UE,也可以为另一个relay UE)之间的承载,则根据第一标识和第二标识可以确定两个UE。relay UE可以按照根据第一标识和第二标识各自确定的UE的速率参数,对第一推荐比特率进行拆分,例如,根据保证比特率(Guaranteed Bit Rate,GBR)数值的比例关系,对第一推荐比特率进行拆分,若两个UE各自的GBR为2Mbps,即一比一的关系,第一推荐比特率为3Mbps,则relay按比例拆分之后,每个UE的比特率为1.5Mbps。
U2U架构中,控制一般为TX UE→RX UE方向:TX remote UE→relay UE(本跳为PC5 LCID粒度)或者relay UE→RX remote UE(本跳为PC5 LCID粒度),也可以反方向控制,控制的粒度是当前接口的LCID。若根据第一映射表确定一个上一跳PC5 LCID映射多个下一跳PC5 LCID,relay UE按照速率组成进行等比划分,将接收的第一推荐比特率分割成多个下一跳PC5推荐比特率。
第一中继终端在接收第一推荐比特率信息之后,可对第一推荐比特率进 行合并后发送。即,在本申请一个实施例中,所述第一目标设备包括至少两个终端,所述终端包括远端终端和第二中继终端中的至少一个,例如,第一目标设备包括两个远端终端,或者包括两个第二中继终端,或者一个远端终端和一个中继终端。所述至少一个承载标识为所述至少两个终端中各终端与所述第一中继终端之间的承载的承载标识;相应的,在所述接收第一目标设备发送的第一推荐比特率信息之后,所述方法还包括:
所述第一中继终端根据所述至少一个承载标识,以及所述第一中继终端存储的第一映射表,确定下一跳对应的第二目标承载标识,所述第一映射表包括所述第一中继终端上一跳对应的承载标识与下一跳对应的承载标识之间的映射关系;
在所述第二目标承载标识仅包括一个承载标识的情况下,所述第一中继终端在所述第二目标承载标识对应的承载上发送推荐比特率之和,其中,所述推荐比特率之和为所述至少一个承载标识中各承载标识对应的第一推荐比特率之和。
例如,第一中继终端将至少一个远端终端中各个终端发送的推荐比特率发送给网络侧设备的情况下,若各个终端发送的推荐比特率可复用到一个Uu LCID,例如,可复用各个终端中具有相同或者近似服务质量(Quality of Service,QoS)请求的数据流,则将各终端发送的推荐比特率之和发送给网络侧设备。
请参见图3,图3是本申请实施例提供的一种推荐比特率确定方法的流程图,如图3所示,本申请实施例提供的推荐比特率确定方法,包括:
步骤301、远端终端执行第二操作,所述第二操作包括如下至少一项:
向第一中继终端发送第一推荐比特率信息;
接收所述第一中继终端发送的第二推荐比特率信息;
其中,所述第一推荐比特率信息包括所述远端终端与所述第一中继终端之间的推荐比特率;
所述第二推荐比特率信息包括所述第一中继终端与所述远端终端之间的推荐比特率。
在中继架构中,远端终端与网络侧设备可通过第一中继终端进行通信,远端终端与其他远端终端之间也通过第一中继终端进行通信。远端终端可以 向第一中继终端发送第一推荐比特率信息,也可以接收第一中继终端发送的第二推荐比特率信息,其中,接收或发送的推荐比特率信息中包括远端终端与第一中继终端之间通信的推荐比特率。
本实施例中,远端终端执行第二操作,所述第二操作包括如下至少一项:向第一中继终端发送第一推荐比特率信息;接收所述第一中继终端发送的第二推荐比特率信息;其中,所述第一推荐比特率信息包括所述远端终端与所述第一中继终端之间的推荐比特率;所述第二推荐比特率信息包括所述第一中继终端与所述远端终端之间的推荐比特率。远端终端通过与第一中继终端之间进行推荐比特率交互,第一中继终端可将其与网络侧设备或其他远端终端之间的推荐比特率进行传递,使得远端终端业务源编码可更好的适应链路情况,提升传输的效率,保障了远端终端的业务体验和系统效率。
可选的,在远端终端向第一中继终端发送第一推荐比特率信息之后,所述方法还包括:
启动禁止定时器,所述禁止定时器用于禁止所述远端终端向所述第一中继终端发送推荐比特率信息。
例如,远端终端向第一中继终端上报一次PC5推荐比特率之后,会启动禁止定时器,在禁止定时器运行期间不允许再次上报,直至定时器超时,再进行上报。
在U2N场景中,网络侧设备是控制方,remote UE是请求方。而在U2U场景中,通信的两端为relay UE和remote UE,或者,一个remote UE与另一个remote UE,第一推荐比特率信息或第二推荐比特率信息中还需要包括指示第一中继终端或远端终端是请求方或控制方的指示信息。请求方也可称为建议方或接收方,控制方也可称为决策方或发送方。
例如,TX UE(即发送UE,发送UE可为relay UE或remote UE)为真正执行业务源速率调整,可以由TX UE作为决策方,决定这个方向的比特率,而RX UE由于是接收方,相对被动,它可以根据自己的测量情况给予建议。
在TX UE1(UE1为控制方)到RX UE2(UE2为请求方)的方向,TX UE1给出的推荐比特率是业务源编码真正执行的速率,而RX UE2给出的推荐比特率可以是这个方向的建议值;反之,在TX UE2(UE2为控制方)到RX UE1 (UE1为请求方)的方向,TX UE2给出的推荐比特率是业务源编码真正执行的速率,而RX UE1给出的推荐比特率可以是这个方向的建议值。
U2U场景中,通信的两端任意一个UE都有权决定,也有权建议,在信令中携带指示信息自身是决定还是建议即可,便于对端尊照或者参考执行。
可选的,所述第一推荐比特率信息包括:与所述远端终端和所述第一中继终端中至少一项相关联的目标对象的推荐比特率,以及指示信息;
和/或,
所述第二推荐比特率信息包括:与所述远端终端和所述第一中继终端中至少一项相关联的目标对象的推荐比特率,以及指示信息;
其中,所述指示信息用于指示所述远端终端或所述第一中继终端为控制方或请求方。
所述指示信息包括如下至少一项:
用于指示控制方向的方向标识位,所述控制方向为所述远端终端向所述第一中继终端的方向,或所述第一中继终端向所述远端终端的方向;
标识位,所述标识位用于指示所述远端终端和所述第一中继终端中的一者为控制方,和/或另一者为请求方。
具体的,为每个方向划分清晰的标识,例如UE1->UE2作为direction 1,UE2->UE1作为direction2,在direction 1方向上,默认UE1决定,UE2建议,在direction 2上,默认UE2决定,UE1建议。direction 1和direction 2即为方向标识位,根据该方向的方向标识位可知UE1、UE2为控制方或请求方。UE1可为远端终端,UE2可为第一中继终端。
若控制UE1到UE2的信令方向,则bit置位为0,如果控制反方向,bit置位为1;bit即为方向标识位,根据该方向的方向标识位可知UE1、UE2为控制方或请求方。
远端终端或所述第一中继终端为控制方还是建议方,可以采取默认的规定,或者显式指示,例如,采用标识位进行指示。举例来说,通过1个比特位携带,若比特位为0表示控制方,比特位为1表示建议方。
可选的,所述目标对象包括如下至少一项:
PC5 LCID;
目的层二标识;
源层二标识;

由于U2U涉及到的是两个UE之间,例如,第一remote UE和relay UE之间,relay UE和第二remote UE之间,在进行推荐比特率交互时可以采用如下粒度:
使用PC5 LCID粒度:指推荐的推荐比特率是针对一个PC5 LCID进行控制或者请求,对于业务源端的UE(业务源端的UE可理解为remote UE)将根据该比特率设置一个逻辑信道的速率;
使用PC5独特的目的层二标识(即Destination L2 ID)粒度:指推荐的推荐比特率是针对一个特定的Destination L2 ID进行控制或者请求,对于业务源端的UE将根据该比特率设置发往一个Destination L2 ID的速率;
使用PC5独特的源层二标识(Source L2 ID)以及Destination L2 ID粒度;指推荐的推荐比特率是针对一个特定的Source L2 ID以及Destination L2 ID进行控制或者请求,对于业务源端的UE将根据该比特率设置由特定Source L2 ID发往特定Destination L2 ID的速率;

使用信道繁忙率(Channel Busy Ratio,CBR)区间(Range)粒度;指推荐的推荐比特率是针对一个特定的CBR区间进行控制或者请求,对于业务源端的UE将根据该比特率设置位于特定CBR区间时的发送速率。
可选的,所述第一中继终端包括至少两个中继终端,所述第二推荐比特率信息包括至少两个中继终端发送的推荐比特率;
在所述接收所述第一中继终端发送的第二推荐比特率信息之后,所述方法还包括:
若所述至少两个中继终端发送的推荐比特率的和大于所述远端终端的最大速率,则所述远端终端将所述和确定为所述远端终端的新的最大速率。
在通信的两个远端终端之间,可以有多条路径可以到达对端,例如第一路径为remote UE1→relay UE 2→relay UE4→remote UE6,即remote UE1发送的推荐比特率可依次经过relay UE 2和relay UE 4,最终到达remote UE6;第二路径为remote UE1→relay UE 3→relay UE5→remote UE6,即remote UE1发送的推荐比特率可依次经过relay UE 3和relay UE 5,最终到达remote UE6,每条路径都有速率调整信息,remote UE6需要综合不同路径的速率调整信息进行加和考虑,若最终总和超出remote UE6的速率上限,则可将最终总和设置为remote UE6的新的最大速率,remote UE6后续在两条路径上按照推荐比例进行速率分布。
请参见图4,图4是本申请实施例提供的一种推荐比特率确定方法的流程图,如图4所示,本申请实施例提供的推荐比特率确定方法,包括:
步骤401、网络侧设备执行第三操作,所述第三操作包括如下至少一项:
向第一中继终端发送的第一推荐比特率信息;
接收所述第一中继终端发送的第二推荐比特率信息;
其中,所述第一推荐比特率信息包括所述网络侧设备与所述第一中继终端之间的推荐比特率;所述第二推荐比特率信息包括所述第一中继终端与所述网络侧设备之间的推荐比特率。
上述中,第一中继终端可基于第一中继终端与网络侧设备之间的链路的质量和容量,确定推荐比特率,发送给网络侧设备;也可以基于第一中继终端与远端终端之间的链路的质量和容量,确定推荐比特率,发送给网络侧设备;还可以将第一中继终端接收的远端终端的推荐比特率发送给网络侧设备。网络侧设备可与第一中继终端进行推荐比特率交互,并通过第一中继终端进行推荐比特率传递,从而根据实际情况调整推荐比特率,使得远端终端业务源编码可更好的适应链路情况,提升传输的效率,保障了远端终端的业务体 验和系统效率。
上述中,所述第一推荐比特率信息和所述第二推荐比特率信息均可包括所述网络侧设备与所述第一中继终端之间的Uu链路的推荐比特率。需要说明的是,第一推荐比特率信息和所述第二推荐比特率信息中的推荐比特率可相同,也可不同。
以下列举具体实施例对本申请提供的推荐比特率确定方法进行举例说明。
本申请的方法可应用在副链路中继架构中,是一种逐跳方式的推荐比特率交互方法,也就是说,推荐比特率的控制和请求过程,均是在直接连接的两个节点之间进行的。
L2 U2N架构和L3 U2N架构中,均可以进行逐跳(Hop-by-hop)的推荐比特率控制和请求,其中控制和请求均是在直接连接的两个节点之间进行。
控制一般为下行方向:gNB→relay UE(这两者之间为Uu LCID粒度)或者relay UE→remote UE(这两者之间为PC5 LCID粒度),控制的粒度是当前接口的LCID。gNB为relay UE的上一跳,remote UE为relay UE的下一跳。若根据第一映射表确定Uu LCID映射多个PC5 LCID,则relay UE按照速率组成进行等比划分,将从gNB接收的第一推荐比特率分割成多个PC5推荐比特率,然后将各PC5推荐比特率通过各PC5 LCID对应的承载进行发送。
请求一般为上行方向:remote UE→relay UE(这两者之间为PC5 LCID粒度)或者relay UE→gNB(这两者之间为Uu LCID粒度),remote UE为relay UE的上一跳,gNB为relay UE的下一跳。relay UE可以根据它接收到的请求信息和自身对两边链路(与gNB之间的Uu链路,以及与remote UE之间的PC5链路)的测量信息,综合之后取值小的推荐比特率,向gNB进行请求。
L2 U2U架构和L3 U2U架构中,均可以进行逐跳(Hop-by-hop)的推荐比特率控制和请求,其中控制和请求均是在直接连接的两个节点之间进行。
控制方向为TX→RX方向:TX remote UE→relay UE(本跳PC5 LCID粒度)或者relay UE→RX remote UE(本跳PC5 LCID粒度),但反方向控制也是可以的,可以默认控制的方向、显式携带方向指示或指示信息,控制的粒度是当前接口的LCID,当一个上一跳PC5 LCID中映射了多个下一跳PC5 LCID 时,由relay UE按照速率组成进行等比划分,将relay UE接收到的推荐比特率分割成多个下一跳PC5推荐比特率。
请求方向为RX→TX方向:RX remote UE→relay UE(本跳PC5 LCID粒度)或者relay UE→TX remote UE(本跳PC5 LCID粒度),但反方向请求也是可以的,可以默认控制的方向、显式携带方向指示或指示信息,relay UE可以根据它接收到的请求信息和自己对两边链路的测量信息,综合之后取小,向remote UE进行请求。
网络侧设备与远端终端之间,或者两个远端终端之间设置一个中继终端,这种架构可理解为单跳架构;网络侧设备与远端终端之间,或者两个远端终端之间设置至少两个中继终端,这种架构可理解为多跳架构。多跳架构是在单跳架构上的不断迭代,多跳架构中也支持上述方式的控制和请求。
在L2 U2N架构和L3 U2N架构中,基站是不可见remote UE,relay UE将remote UE的数据需求当成自己的需求,向基站进行请求,因此基站看到的都是relay UE的传输需求。这样,在relay UE的Uu接口上,基站可向relay UE发送携带推荐比特率的MAC CE,用于推荐上行/下行的推荐比特率,同样的,relay UE也可以向基站发送上下行的推荐比特率请求。
对于relay UE来说,如果接收到基站发送的上行/下行的推荐比特率,由于其中是携带LCID的,relay UE可获知是对哪个逻辑信道进行的推荐比特率调整。relay UE的一个无线承载/逻辑信道里,可以复用不同remote UE的具有相同或者近似QoS请求的数据流,也就是说,一个relay UE的Uu LCID里,是可以复用不同remote UE的数据流的,由于上行推荐比特率最终调整的是remote UE的业务源编码速率,下行推荐比特率也与remote UE的下行接收相关,relay UE会将接收到的推荐比特率信息,转发给涉及的不同remote UE,过程如下:
如果relay UE接收到推荐比特率信息(基站发送的)包括的LCID对应的逻辑信道上,只有一个remote UE的数据流,则relay UE可以直接根据推荐比特率信息组织一个相同的PC5推荐比特率发给给remote UE;
如果relay UE接收到推荐比特率信息包括的LCID对应的逻辑信道上,有两个或者两个以上remote UE的数据流,则relay UE可以按照这两个或者两个UE各自的速率参数,例如GBR数值的比例关系,对基站发送的推荐比特率信息包括的推荐比特率进行按比例拆分,例如两个UE各自GBR为2Mbps,即一比一的关系,推荐比特率信息包括的推荐比特率为3Mbps,则relay UE按比例拆分之后,每个remote UE的推荐比特率为1.5Mbps;
relay UE将完成拆分之后的推荐比特率,分别组织PC5推荐比特率,发送给涉及的remote UE。
remote UE或者relay UE如果发现自己的链路情况不好,不能容纳现有的业务源速率,也可以向基站进行推荐比特率的建议:
如果是relay UE,则它可以测量Uu链路和PC5链路,综合考虑Uu链路和PC5链路的质量和容量,以较小的那个来决定推荐比特率;
relay UE测量的Uu链路/容量,一般可以直接决定Uu LCID级别(即可能是多个remote UE的聚合级别)的推荐比特率,直接上报给基站供参考;
relay UE测量的PC5链路/容量,一般是基于每个remote UE级别的,因此可以先形成针对每个remote UE的推荐比特率,再将可复用到一个Uu LCID对应的逻辑信道的不同remote UE的推荐比特率加和,形成Uu LCID级别的推荐比特率,上报给基站供参考;
relay UE上报一次Uu推荐比特率之后,会启动禁止定时器,在定时器运行期间不允许再次上报,直至定时器超时,再进行上报;
如果是remote UE,由于它看到的只有PC5链路质量和容量,因此remote UE可以向relay UE上报PC5 LCID对应的逻辑信道的推荐比特率请求,relay UE将可复用到一个Uu LCID对应的逻辑信道的不同remote UE的推荐比特率进行加和处理,形成Uu LCID级别的推荐比特率请求,上报给基站;
Remote UE上报一次PC5 LCID对应的逻辑信道推荐比特率之后,会启动禁止定时器,在定时器运行期间不允许再次上报,直至定时器超时,再进行上报;
relay UE上报一次Uu LCID对应的逻辑信道的推荐比特率之后,会启动禁止定时器,在定时器运行期间不允许再次上报,直至定时器超时,再进行上报。
在L2中继架构中,由于在承载映射方面有类似性,一个remote UE的端到端(E2E)无线承载(Radio Bearer,RB)一般在PC5接口(interface)映射到一个RLC承载或LCID上,多个remote UE的E2E RB在relay UE Uu就接口可以复用到一个RLC承载或LCID上,上述推荐比特率请求在L2架构的基站、relay UE和remote UE之间也可以适用。
U2U场景中,即remote UE的通信对端是另一个remote UE,但是这两种是直接通信,也可以进行推荐比特率的控制和请求。
两端分别发送推荐比特率信息,remote UE1和relay UE2之间发送他们之间PC5接口的LCID粒度的推荐比特率控制或者建议信息,相应的,relay UE2和对端remote UE2之间也发送他们之间PC5接口的LCID粒度的推荐比特率控制或者建议信息。由relay UE考虑LCID内部的E2E RB的映射与加和关系,进行一定的等比例换算和分摊,具体可参见前文陈述,在此不再赘述。
在这种方式中,由于每一段控制的都是各自段的LCID粒度的推荐比特率,可引入方向位、控制位或者请求位来指示控制的方向和建议的方向,即确定哪个远端终端为控制方或建议方。
U2U场景中,任意一个remote UE或者relay UE可以向自己的上一跳节点进行推荐比特率的请求过程,例如remote UE可以向relay UE请求,relay UE可以向另一端remote UE请求,请求都是根据自己当前判断的链路容量以及能够掌握的其它链路容量综合考虑,并在多种容量中取小,进行逐步请求推荐比特率上报,并供最终端的remote UE决定最终的推荐比特率控制信息内容。
前面以单跳来举例,即中间只有一个relay UE。但在复杂的场景中,无论是U2N还是U2U都可能会涉及到多跳的场景。
以每一跳的信令进行逐级传递,接收节点再根据速率组成向后续节点进 行按比例分发或者合并。
分发的情况,例如第一跳的一个LCID对应两个第二跳的LCID,且两个第二跳的LCI对应的逻辑信道的速率相等,则第二跳分别发送两个推荐比特率信息给两个第二跳端点,且推荐比特率均为初始值的一半,第三跳又各自包含两个LCID且速率相等,则第三跳每个分支分别发送两个推荐的比特率信息给两个第三跳端点,且推荐的比特率均为接收到值的一半,即初始推荐比特率值的1/4,依次类推,直到最终的remote UE收到推荐比特率;
合并的情况,主要应用于在两个最终节点之间,有多条路径可以到达对端,例如remote UE1→relay UE 2→relay UE4→gNB/Remote UE6和remote UE1→relay UE 3→relay UE5→gNB/Remote UE6,每条路径可能都有速率调整信息,最终gNB或Remote UE6需要综合不同路径的速率调整信息进行加和考虑,如果最终总和超出了上限,则将最终总和设置为gNB或Remote UE6的上限,并在两条路径按照推荐比例进行速率分布。
本申请给出了在副链路中继架构中remote UE和其服务基站,以及remote UE与对端的remote UE之间,进行逐跳推荐比特率交互及传递的方法,能够使得remote UE业务源编码更好的适应链路情况,提升了传输的效率,保障了remote UE的业务体验和系统效率。
