具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员所获得的所有其他实施例,都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象,而不用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换,以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施,且“第一”、“第二”所区别的对象通常为一类,并不限定对象的个数,例如第一对象可以是一个,也可以是多个。此外,说明书以及权利要求中“和/或”表示所连接对象的至少其中之一,字符“/”一般表示前后关联对象是一种“或”的关系。
值得指出的是,本申请实施例所描述的技术不限于长期演进型(Long  Term Evolution,LTE)/LTE的演进(LTE-Advanced,LTE-A)系统,还可用于其他无线通信系统,诸如码分多址(Code Division Multiple Access,CDMA)、时分多址(Time Division Multiple Access,TDMA)、频分多址(Frequency Division Multiple Access,FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access,OFDMA)、单载波频分多址(Single-carrier Frequency Division Multiple Access,SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用,所描述的技术既可用于以上提及的系统和无线电技术,也可用于其他系统和无线电技术。以下描述出于示例目的描述了新空口(New Radio,NR)系统,并且在以下大部分描述中使用NR术语,但是这些技术也可应用于NR系统应用以外的应用,如第6代(6th Generation,6G)通信系统。
为了便于理解本申请实施例,下面先介绍以下技术点:
一、关于Sidelink Relay机制
无线通信系统中的Relay技术,就是在基站与终端之间增加了一个或多个中继节点,负责对无线信号进行一次或者多次的转发,即无线信号要经过多跳才能到达终端。
无线中继技术不仅可用于扩展小区覆盖,弥补小区覆盖盲点,同时也可通过空间资源复用提升小区容量。对于室内覆盖,Relay技术也可起到克服穿透损耗,提升室内覆盖质量的作用。
以较简单的两跳中继为例,无线中继就是将一个基站—终端链路分割为基站—中继站和中继站—终端两个链路,从而有机会将一个质量较差的链路替换为两个质量较好的链路,以获得更高的链路容量及更好的覆盖。
目前长期演进(Long Term Evolution,LTE)中已经支持的Relay为终端到网络的中继(UE-to-Network(U2N)relay),即Relay一端连接UE,一端连接网络侧。跟Relay连接的UE,叫做远端UE(Remote UE)。
新空口(New Radio,NR)也将研究如何支持UE-to-Network Relay机制,典型场景如图1。Remote UE需要与网络侧传输数据,但由于覆盖不佳,找到Relay UE为其中转,其中Relay UE与基站之间是Uu接口,Relay UE和Remote UE之间是sidelink(PC5)接口。一般来说,Relay UE是开放的,可以为任何 Remote UE服务。
NR还将研究如何支持UE-to-UE(U2U)Relay机制,典型场景如图2所示:中间是Relay UE,两端是Remote UE,两端Remote UE由于信号质量不佳,他们的数据传输通过中间的Relay UE中转。数据发送端的Remote UE也称之为源UE(Source UE),数据接收端的Remote UE也称之为目的或目标UE(Destination/Target UE)。
二、关于NR Sidelink BSR(缓存状态报告)格式:
参见图3,NR Sidelink BSR沿用了LTE Sidelink BSR的设计,唯一的不同在于LCG ID、Destination Index和缓冲区大小(Buffer Size,BS)这3个域,或字段(field)的长度定义发生了变化,即:
LCG ID占3比特,最多被分为8组。
Destination Index占5比特,最多有32个组,对应32个Destination L2 ID。
Buffer Size长为8比特,最多有256种BS等级。
而且针对Destination index取值N分别为偶数和奇数的情况,格式是通用的。如图3所示:
三、关于资源分配模式:
Sidelink UE的资源分配模式总共分为两类:
1)基站调度模式(Mode 1):由网络侧设备(基站)控制并为每个UE分配资源(BS schedules SL resource(s)to be used by UE for SL transmission(s))。
2)UE自主模式(Mode 2):由每个UE自主选择资源(UE determines,i.e.BS does not schedule,SL transmission resource(s)within SL resources configured by BS/network or pre-configured SL resources)。
根据现有SL BSR机制,LCG ID数量的上限是8,Destination index数量的上限是32。目前的LCG ID数量或Destination Index数量上限可能不足以满足Sidelink relay场景的需求,导致远端UE和/或中继UE无法很好的使用mode 1资源分配模式,导致在Sidelink relay场景中基站无法为终端进行Sidelink资源调度,影响通信效率。
图4示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端41、终端42和网络侧设备43。其中,终端41、终端42可以是 手机、平板电脑(Tablet Personal 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)、增强现实(augmented reality,AR)/虚拟现实(virtual reality,VR)设备、机器人、可穿戴式设备(Wearable Device)、车载设备(Vehicle User Equipment,VUE)、行人终端(Pedestrian User Equipment,PUE)、智能家居(具有无线通信功能的家居设备,如冰箱、电视、洗衣机或者家具等)、游戏机、个人计算机(personal computer,PC)、柜员机或者自助机等终端侧设备,可穿戴式设备包括:智能手表、智能手环、智能耳机、智能眼镜、智能首饰(智能手镯、智能手链、智能戒指、智能项链、智能脚镯、智能脚链等)、智能腕带、智能服装等。需要说明的是,在本申请实施例并不限定终端41和终端42的具体类型。网络侧设备43可以包括接入网设备或核心网设备,其中,网络侧设备43也可以称为无线接入网设备、无线接入网(Radio Access Network,RAN)、无线接入网功能或无线接入网单元。接入网设备43可以包括基站、无线局域网(WLAN,Wireless Local Area Network)接入点或WiFi节点等,基站可被称为节点B、演进节点B(Evolved Node B,eNB)、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)、家用B节点、家用演进型B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系统中的基站为例进行介绍,并不限定基站的具体类型。
