技术领域
本申请属于无线通信技术领域,具体涉及一种旁链路资源选择方法及终端。
背景技术
新无线(New Radio,NR)旁链路(SideLink,SL,也可以称为侧链路,副链路等)资源选择方式有两种,一种基于基站调度(mode 1),另一种基于用户设备(User Equipment,UE,也称为终端)自主选择(mode 2)。对于基站调度的资源选择方式,UE用于数据传输的旁链路资源由基站决定,并通过下行信令通知发送端(TX)UE;对于UE自主选择的资源选择方式,UE在(预)配置的资源池中选择可用的传输资源,UE在进行资源选择之前先进行信道监听,根据信道监听结果选择出干扰较小的备选资源集合(candidate resource set),再从所述备选资源集合中随机选择用于传输的资源。
3GPP即将讨论对mode 2的资源选择方式的增强。如下方案为备选项:UE-A决定一个建议的资源集合,UE-A将建议的资源集合通知给UE-B,UE-B在进行mode 2资源选择时可以考虑UE-A所通知的建议的资源集合。
由于根据现有的mode 2资源选择方式以及根据增强后的mode 2资源选择方式,会得到不同的备选资源集合,那么,UE在进行资源选择时,如果随意采用现有的或增强的资源选择方式,传输的可靠性则无法保证。
另外,UE判断资源抢占和/或进行资源选择重评估时,是否进行资源重选会有至少两种不同的依据。UE在得到这些模糊的依据时,进行不必要的资源重选,会破坏系统整体的传输可靠性;或,UE在需要进行资源重选的时候而没有及时重选资源,造成系统/其他UE的传输性能下降。
另外,UE可以进行资源预留。假设UE在资源选择时采用现有的资源选择方式,所选的资源进行了资源预留。UE在传输新的传输块(TB)时,可能需要采用增强的资源选择方式,所以预留的资源可能不再适合新的传输,因而需要触发资源重选。

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、完整地描述,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在没有作出创造性劳动前提下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数据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。然而,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,尽管这些技术也可应用于NR系统应用以外的应用,如第6代(6 th Generation,6G)通信系统。
图1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11和网络侧设备12。其中,终端11也可以称作终端设备或者用户终端(User Equipment,UE),终端11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)、可穿戴式设备(Wearable Device)或车载设备(VUE)、行人终端(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。
下面首先对NR SL资源分配/选择进行简单介绍。
NR旁链路资源选择方式有两种,一种基于基站调度(mode 1),另一种基于用户设备(User Equipment,UE,也称为终端)自主选择(mode 2)。
对于mode 2,具体的工作方式如下:1)发送终端(TX UE)在资源选择被触发后,首先确定资源选择窗口,资源选择窗口的下边界在资源选择触发后的T1时间,资源选择的上边界在资源选择触发后的T2时间,其中,T2是UE实现的方式在其TB传输的包延迟预算(packet delay budget,PDB)内选择的值,T2不早于T1。2)UE在资源选择之前,需要确定资源选择的备选资源集合(candidate resource set),根据资源选择窗口内的资源上测量的参考信号接收功率(Reference Signal Received Power。RSRP)与相应的RSRP门限(threshold)做对比,如果RSRP高于RSRP门限,那么对该资源进行资源排除,不能纳入备选资源集合。进行资源排除后资源选择窗口内剩余的资源组成备选资源集合。备选资源集合中的资源在资源选择窗口中的资源的占比要不少于X%(X的取值可以为20,35,50),如果少于X%,RSRP门限需要按照步进值(如3dB)进行增加,再进行所述资源排除操作,直到可以选出不少于所述X%的资源。3)备选资源集合确定后,UE随机在备选资源集合中选择传输资源。另外,UE在本次传输可以为接下来的传输预留传输资源。
示例性的,对于mode 2资源选择方式的增强包括多种方式,例如利用辅 助信息限制资源选择窗口[T1,T2]的确定方式、改变资源选择中RSRP测量值或RSRP门限值、区分资源集合内外备选资源的选中概率等等。特别的,根据现有的mode 2资源选择方式以及部分增强后的mode 2资源选择方式,会得到不同的备选资源集合。

1)基于是否满足预设条件,确定所述目标操作是否能够采用所述第二资源选择方式;
可选的,所述预设条件由协议规定、控制节点配置、控制节点预配置或其他终端指示。

c)传输的媒体接入控制协议数据单元(MAC PDU)或传输块的特性;
UE进行不同类型的TB或MAC PDU传输时,适合采用不同(传统的/增强的)资源选择方式进行资源选择。同理,UE有可能不适合在单一的资源选择方式所预留的资源上进行不同类型的TB或MAC PDU传输。
例如,传输的MAC PDU的服务质量(QoS)、优先级(priority)、延迟(latency)和/或可靠性(reliability)等满足预设要求能够使用第二资源选择方式。
再例如,一个MAC PDU使用第二资源选择方式需要满足该MAC PDU在之前已经传输失败x次,x为大于或等于1的正整数。
d)传输类型,所述传输类型包括:单播、组播和广播中的至少一项;
例如,第二资源选择方式只适用于单播(unicast)和/或组播(groupcast)和/或广播(broadcast)传输。
例如,传输的目的标识(destination ID)指向特定的终端或终端组(group)(例如辅助信息的发送或接收终端或终端组)时能够使用第二资源选择方式。
对于资源选择辅助信息的发送或接收终端,适用的传输类型可以不同。 例如,资源选择辅助信息的接收终端进行单播传输时,采用第二资源选择方式;而资源选择辅助信息的发送终端进行单播、组播和广播传输时,均需采用第二资源选择方式。
e)所述终端和/或接收终端支持的能力或类型;

f)所述终端和/或接收终端处于指定小区覆盖范围内或指定旁链路同步信号(SLSS)覆盖范围内。
例如,基站配置某小区的资源给UE-A,UE-A转发给UE-B,UE-B基于该资源进行传输,此时,该资源使用的资源选择方式只在基站覆盖内有效/UE-A的覆盖范围内有效。
2)基于终端实现确定所述目标操作是否能够采用所述第二资源选择方式。
终端实现即终端自身决定。
(2)确定采用的资源选择方式
本申请实施例中,可选的,若初始资源选择不能够采用所述第二资源选择方式,确定初始资源选择采用所述第一资源选择方式。初始资源选择不能够采用所述第二资源选择方式可以根据上述预设条件判断,也可以是终端实现确定。
可选的,若不满足(或者不能预估是否满足)所述预设条件,确定初始资源选择不能够采用所述第二资源选择方式。
可选的,若满足所述预设条件,确定初始资源选择能够采用所述第二资源选择方式,即,初始资源选择能够同时采用所述第一资源选择方式和所述第二资源选择方式。

本申请实施例中,对初始资源选择使用的资源选择方式进行明确,避免随意采用传统的(即现有的)/增强的资源选择方式,TB传输的可靠性无法保证的问题。
(二)所述目标操作为资源选择重评估或资源抢占检测
下面首先对资源选择重评估和资源抢占检测分别进行说明。
1)资源选择的重评估
在Mode 2资源选择方式中,资源选择的重评估(re-evaluation)机制被支持,该机制的简要描述如下:UE为了判断已经选择但未预留的资源(PSCCH/PSSCH资源)是否仍为空闲或低干扰状态,UE至少在‘m-T3’时刻进行资源选择的重评估,‘m’时刻是该资源的预留信息首次发送的时刻,T3至少包括UE进行资源选择处理的时长。UE至少在‘m-T3’重新执行资源选择的步骤,得到备选资源集合。如果UE所选资源仍在该备选资源集合中,UE无需进行资源重选;否则,UE在备选资源集合中选择新的传输资源。
2)资源抢占(Resource pre-emption)
在Mode 2资源选择方式中,资源抢占机制被支持,该机制的简要描述如下:一个UE已经预留的资源和其它具有更高优先级业务的UE所预留或选择的资源重叠(或部分重叠),如果该UE在相关资源上的SL-RSRP测量值 大于某个关联的(associated)SL-RSRP门限值时,该UE会触发资源的重新选择。
UE为了判断已经预留的资源(PSCCH/PSSCH资源)是否被抢占,参见图3,UE至少在‘m-T3’时刻进行抢占检测,‘m’时刻是该资源所在的时刻或者是该资源的预留信息发送的时刻,T3至少包括UE进行资源选择处理的时长。UE至少在‘m-T3’重新执行资源选择的步骤,得到备选资源集合。如果UE所选资源仍在该备选资源集合中,UE无需进行资源重选;否则,UE在备选资源集合中选择新的传输资源。
(1)确定资源选择重评估或资源抢占检测是否能够采用所述第二资源选择方式
本申请实施例中,可以采用以下方式之一确定资源选择重评估或资源抢占检测是否能够采用第二资源选择方式:

所述激活时段可以由其他终端激活,例如通过接收到其他终端发送的资源选择辅助信息或接收到其他终端发送的激活指示信息进行激活。
b)频域资源条件;
例如,在某些载频、带宽部分(BWP)或资源池(resource pool)能够使用第二资源选择方式。
c)传输的媒体接入控制协议数据单元(MAC PDU)或传输块(TB)的特性;
UE进行不同类型的TB或MAC PDU传输时,适合采用不同(传统的/增强的)资源选择方式进行资源选择。同理,UE有可能不适合在单一的资源选 择方式所预留的资源上进行不同类型的TB或MAC PDU传输。
例如,传输的MAC PDU的服务质量(QoS)、优先级(priority)、延迟(latency)和/或可靠性(reliability)等满足预设要求能够使用第二资源选择方式。
再例如,一个MAC PDU使用第二资源选择方式需要满足该MAC PDU在之前已经传输失败x次,x为大于或等于1的正整数。
d)传输类型,所述传输类型包括:单播、组播和广播中的至少一项;
例如,第二资源选择方式只适用于单播(unicast)和/或组播(groupcast)和/或广播(broadcast)传输。
例如,传输的目的标识(destination ID)指向特定的终端或终端组(group)(例如辅助信息的发送或接收终端或终端组)时能够使用第二资源选择方式。
对于资源选择辅助信息的发送或接收终端,适用的传输类型可以不同。例如,资源选择辅助信息的接收终端进行单播传输时,采用第二资源选择方式;而资源选择辅助信息的发送终端进行单播、组播和广播传输时,均需采用第二资源选择方式。
e)所述终端和/或接收终端支持的能力或类型;
所述终端和/或接收终端支持的能力或类型需要支持第二资源管理方式。所述终端和/或接收终端支持的能力或类型例如为车辆(Vehical)UE或行人(Pedestrian)UE等。
f)所述终端和/或接收终端处于指定小区覆盖范围内或指定旁链路同步信号(SLSS)覆盖范围内。
例如,基站配置某小区的资源给UE-A,UE-A转发给UE-B,UE-B基于该资源进行传输,此时,该资源使用的资源选择方式只在基站覆盖内有效/UE-A的覆盖范围内有效。
2)基于终端实现确定资源选择重评估或资源抢占检测是否能够采用所述第二资源选择方式。
终端实现即终端自身决定。
3)基于是否满足预设条件和第一预设规则,确定所述目标操作是否能够采用所述第一资源选择方式。
可选的,所述第一预设规则包括以下至少之一:
a)资源选择重评估或资源抢占检测与初始资源选择采用相同的资源选择方式;
b)对于同一个传输块的多个旁链路传输资源采用相同的资源选择方式。
本申请的一个应用场景示例如下:在初始资源选择后,激活了第二资源选择方式,此时资源选择重评估不必采用第二资源选择方式,即便协议规定采用或/至少采用第二资源选择方式。
本申请实施例中,所述初始资源选择可以包括以下至少之一:
TB的初始资源选择;
旁链路授权(SL grant)/旁链路进程(SL process)的初始资源选择。
(2)确定资源选择方式
1)在本申请的一些实施例中,可选的,无论资源选择重评估或资源抢占检测是否能够采用所述第二资源选择方式,确定资源选择重评估或资源抢占检测采用所述第一资源选择方式。
也即可以不考虑预设条件,直接确定资源选择重评估或资源抢占检测采用所述第一资源选择方式。
2)在本申请的一些实施例中,可选的,若资源选择重评估或资源抢占检测不能够采用所述第二资源选择方式,确定资源选择重评估或资源抢占检测采用或者至少采用所述第一资源选择方式。资源选择重评估或资源抢占检测不能够采用所述第二资源选择方式可以根据上述预设条件判断,也可以是终端实现确定。
可选的,若不满足(或者不能预估是否满足)所述预设条件,确定资源选择重评估或资源抢占检测不能够采用所述第二资源选择方式。
所述不能预估是否满足预设条件的示例包括:判断周期性预留资源是否需要被抢占的时候,UE在某些情况下不能预估下一周期的资源上的MAC PDU传输特性是否满足预设条件。
3)在本申请的一些实施例中,可选的,若资源选择重评估或资源抢占检测能够同时采用所述第一资源选择方式和所述第二资源选择方式,基于第一方式确定的资源选择重评估或资源抢占检测采用的资源选择方式包括以下之 一:
a)所述第一资源选择方式;
即只采用第一资源选择方式进行资源选择。
b)至少包括所述第一资源选择方式;
即至少采用第一资源选择方式进行资源选择。可以采用第二资源选择方式进行资源选择,也可以不采用第二资源选择方式。
c)所述第二资源选择方式;
即只采用第二资源选择方式进行资源选择。
d)至少包括所述第二资源选择方式;
即至少采用第二资源选择方式进行资源选择。可以采用第一资源选择方式进行资源选择,也可以不采用第一资源选择方式。
e)所述第一资源选择方式和所述第二资源选择方式。
即同时采用第一资源选择方式和第二资源选择方式进行资源选择。
可选的,所述第一方式为以下之一:
1)协议规定、控制节点配置、控制节点预配置或其他终端指示;
所述控制节点可以为基站或者其他终端。所述其他终端指示例如为发送资源辅助信息的终端指示。
2)终端实现;
终端实现即终端自身决定。
在本申请的一些实施例中,可选的,所述控制节点配置或其他终端指示的内容包括:资源选择辅助信息,所述资源选择辅助信息包括以下至少之一:建议的资源集合的指示信息、资源的干扰情况、资源的使用情况、资源的碰撞情况、资源的预留情况、资源上的传输信息特性等等。可选的,所述其他终端可以为接收终端(RX UE)或者其他非接收终端。
UE在进行资源选择重评估或资源抢占检测时,如果随意采用传统的(即现有的)或增强的资源选择方式进行判断,会造成资源重选的错误判断。本申请实施例中,对资源选择重评估或资源抢占检测时采用的资源选择方式进行明确,避免了错误判断资源重选的问题。
另外,若资源选择重评估或资源抢占检测可以同时采用传统的(即现有的) 和增强的资源选择方式进行判断,UE判断资源抢占检测或进行资源选择重评估时,是否进行资源重选会有至少两种不同的依据。本申请中,对资源重选的依据进行明确,避免UE进行不必要的资源重选,从而破坏系统整体的传输可靠性;或,避免UE在需要进行资源重选的时候而没有及时重选资源,造成系统/其他UE的传输性能下降的问题。
(3)资源重选的触发
在本申请的一些实施例中,可选的,根据确定的资源选择方式执行所述目标操作包括:若只使用所述第一资源选择方式和所述第二资源选择方式其中之一执行所述资源选择重评估或资源抢占检测,根据使用的资源选择方式,确定是否触发资源重选。可选的,若选择的资源不在使用的资源选择方式确定的备选资源集合中,确定触发资源重选,否则,确定不触发资源重选。

2)在本申请的一些实施例中,可选的,确定是否触发资源重选之后还包括:若同时使用所述第一资源选择方式和所述第二资源选择方式执行所述目标操作,且所述第一资源选择方式和所述第二资源选择方式均触发了资源重选,基于第二方式确定资源重选使用的目标备选资源集合。
可选的,所述第二方式包括以下之一:
a)协议规定、控制节点配置、控制节点预配置或其他终端指示;
b)终端实现;
c)第二预设规则。
可选的,所述第二预设规则包括:将能够选择出满足HARQ RTT条件的旁链路传输资源的备选资源集合作为所述目标备选资源集合。
下面对HARQ RTT条件进行简单说明。
至少针对mode 2,为了保证PSSCH重传的资源出现在TX UE解调反馈信息之后,规定任意两次选择的PSSCH传输资源间的时间间隔需要大于混合自动重传请求往返时间(HARQ RTT)时间(即下述Z=a+b为所述HARQ RTT时间)。a是第一个资源的PSSCH(共享信道)传输的最后一个符号的结束和相应PSFCH(反馈信道)接收的第一个符号的开始之间的时间间隔,由资源池配置和MinTimeGapPSFCH和periodPSFCHresource的更高层参数确定。b是PSFCH接收和处理加旁链路重传准备所需的时间,包括必要物理信道的多路复用和任何TX-RX/RX-TX切换时间,由UE实现确定。
图4为a和b的示意图。图4中b值较小,PSFCH接收和处理/重传的准备能够在物理旁边链路反馈信道(Physical Sidelink Feedback Channel,PSFCH)所在时隙(slot)内完成,则说明第一个PSCCH/PSSCH资源和第二个PSCCH/PSSCH资源满足HARQ RTT时间要求。
可选的,上述确定的目标备选资源集合为以下之一:
a)所述第一资源选择方式确定的备选资源集合;
b)所述第二资源选择方式确定的备选资源集合。
c)所述第一资源选择方式和所述第二资源选择方式确定的备选资源集合确定的目标备选资源集合。
可选的,可以在目标备选资源集合中随机选择一个资源。
3)在本申请的一些实施例中,可选的,若同时使用所述第一资源选择方式和所述第二资源选择方式进行旁链路传输资源选择,且所述第一资源选择方式和所述第二资源选择方式其中之一触发了资源重选,基于所述第一资源选择方式和所述第二资源选择方式确定的备选资源集合确定目标备选资源集合。
可选的,若目标备选资源集合基于所述第一资源选择方式和所述第二资源选择方式确定,所述目标备选资源集合为所述第一资源选择方式和所述第二资源选择方式确定的备选资源集合的交集或并集。
可选的,可以在备选资源集合中随机选择一个资源。
在本申请的一些实施例中,可选的,若采用所述第二资源选择方式执行所述资源选择重评估或资源抢占检测,向接收终端发送信令,以触发所述接收终端上报资源选择辅助信息,所述资源选择辅助信息包括以下至少之一:建议的资源集合的指示信息、资源的干扰情况、资源的使用情况、资源的碰撞情况、资源的预留情况、资源上的传输信息特性等等。
(三)所述目标操作为资源重选
在本申请的一些实施例中,可选的,若所述终端预留的旁链路传输资源没有在建议的资源集合中,确定触发资源重选;
或者,若所述终端预留的旁链路传输资源在建议的资源集合中,确定触发资源重选。
例如UE在资源选择时采用第一资源选择方式,所选的资源进行了资源预留。UE在传输新的TB时,可能需要采用第二资源选择方式,所以预留的资源可能不再适合新的TB传输,因而需要触发资源重选。
所述预留为周期性预留和/或非周期预留。
在NR SL中,发送终端(TX UE)会对其选择的资源进行资源预留(预 留分为周期性预留和非周期性预留),预留资源为以后的物理旁边链路控制信道(Physical Sidelink Control Channel,PSCCH)或物理旁链路共享信道(Physical Sidelink Shared Channel,PSSCH)传输所用。
非周期预留可以通过旁链路控制信息(Sidelink Control Information,SCI)中的时域资源分配(Time resource assignment)域实现,预留的资源至少可以用作同一个TB的传输。
周期预留可以通过SCI中的资源预留周期(Resource reservation period)域实现,当前周期预留的周期性资源可以用作下一个TB的传输。
下面结合具体实施例,对本申请的方法进行举例说明。
实施例一
在一个实施例中,若TX UE接收到的资源选择辅助信息能够反映RX UE检测到的资源干扰情况,则TX UE能够采用第二资源选择方式,但不要求TX UE必须采用第二资源选择方式。
在另一个实施例中,若TX UE接收到的资源集合指示信息反映RX UE的接收时间段,TX UE必须采用第二资源选择方式。
实施例二
(1)UE根据从另一个UE接收的资源选择辅助信息(资源选择辅助信息可能包括资源干扰情况和/或建议的资源集合的指示信息)的内容判定目标操作采用的资源选择方式。
例如,满足以下至少之一,判定目标操作采用的资源选择方式为:1)第一资源选择方式;或,至少包括第一资源选择方式;或,第二资源选择方式;或,至少包括第二资源选择方式;或,第一资源选择方式和第二资源选择方式:
1)接收的资源选择辅助信息反映另一个UE检测到的资源干扰情况。
2)接收的建议的资源集合的指示信息反映该UE和/或另一个UE的资源选择倾向。例如:
a)优先选择resource set的资源(例如UE使用第二资源选择方案,优先选择resource set内的资源。
b)只选择或不选择resource set内的资源(例如UE使用第二资源选择方 案,只选择或不选择resource set内的资源。
3)接收的建议的资源集合的指示信息反映该UE所在的UE组的资源使用(例如使用资源进行信息发送)倾向。
该场景为一个UE向一组UE或一组UE中的部分UE发送资源选择辅助信息的场景。
4)接收的建议的资源集合的指示信息反映另一个UE的接收时间段。例如DRX on时间。
(2)UE根据自身发送的资源选择辅助信息(资源选择辅助信息可能包括资源干扰情况和/或建议的资源集合的指示信息)的内容判定目标操作采用的资源选择方式。
例如,满足以下至少之一,判定目标操作采用的资源选择方式为:1)第一资源选择方式;或,至少包括第一资源选择方式;或,第二资源选择方式;或,至少包括第二资源选择方式;或,第一资源选择方式和第二资源选择方式:
1)发送的资源选择辅助信息反映UE检测到的资源干扰情况。
2)发送的建议的资源集合的指示信息反映该UE和/或另一个UE的资源选择倾向。例如:
a)优先选择resource set的资源(例如UE使用第二资源选择方案,优先选择resource set内的资源。
b)只选择或不选择resource set内的资源(例如UE使用第二资源选择方案,只选择或不选择resource set内的资源。
3)发送的建议的资源集合的指示信息反映该UE所在的UE组的资源使用(例如使用资源进行信息发送)倾向。
该场景为一个UE向一组UE或一组UE中的部分UE发送资源选择辅助信息的场景。
4)发送的建议的资源集合的指示信息反映改UE的接收时间段。例如DRX on时间。
实施例三
在一个实施例中,TX UE接收来自RX UE的建议的资源集合的指示信 息,指示RX UE只能在特定的资源上进行接收(例如DRX on时间)。TX UE需要向该RX UE发送TB或MAC PDU。TX UE在本次发送之前,发送了信息(例如广播传输)且预留了资源。对于本次发送,如果TX UE判断所预留的资源不在RX UE所建议的资源集合内,TX UE需要进行资源重选。
在另一个实施例中,TX UE接收来自RX UE的建议的资源集合的指示信息,指示RX UE只能在特定的资源上进行接收(例如DRX on时间)。TX UE需要向该RX UE发送TB或MAC PDU。在TB重传的时候,TX UE接收到RX UE改变了的建议的资源集合的指示信息,如果为本次TB传输预留的资源不在新的建议的资源集合内,TX UE进行资源重选。
本申请实施例中,明确了当目标操作能够同时采用传统的资源选择方式和增强的资源选择方式时,如何确定目标操作采用的资源选择方式,而非随意选择现有的或增强的资源选择方式,避免了不必要的资源选择,或者资源重选的错误判断,以保证传输的可靠性。同时,明确了资源重选的触发条件,保证终端选择合适的传输资源,提高传输的可靠性和有效性。
