Description

一种信号发送和检测的方法及装置
本申请要求在2014年6月25日提交中国专利局、申请号为201410291316.0、发明名称为“一种信号发送和检测的方法及装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域,尤其涉及一种信号发送和检测的方法及装置。
背景技术
D2D(Device-to-Device,设备到设备)技术,是指邻近的UE(User Equipment,用户设备)可以在近距离范围内通过直连链路进行数据传输的方式,不需要通过中心节点进行转发,D2D技术本身的短距离通信特点和直接通信方式使其具有如下优势:UE近距离直接通信方式可实现较高的数据速率、较低的延迟和较低的功耗;利用网络中广泛分布的UE以及D2D通信链路的短距离特点,可以实现频谱资源的有效利用;D2D的直接通信方式能够适应本地数据共享需求,提供具有灵活适应能力的数据服务;D2D直接通信能够利用网络中数量庞大且分布广泛的UE以拓展网络的覆盖范围。
为了保证传输的可靠性,D2D通信中,UE(User Equipment,用户设备)在发送信号时,在一个传输周期内可能使用一个物理资源发送一次信号,也可能使用多个物理资源发送重复的信号。此时,接收端的UE需要知道所检测的信号的重复传输配置信息,即信号的重复传输次数和/或每次重复传输所用的物理资源,才能进行信号的关联检测。如果UE支持在一个传输周期内针对一个信号进行重复传输,以提高传输可靠性,则重复传输所使用的物理资源是关联的,即重复传输的物理资源具有一定的时域或者频域跳频关系。
现有技术中UE在一个传输周期内针对一个信号进行重复传输时,如何使得接收端UE在检测信号时确定信号的重复传输配置信息是需要解决的问题,目前并没有具体方案。

具体实施方式
本申请实施例提供一种信号发送和检测的方法及装置,用户设备将信号的重复传输配置信息通过同步信道发送,当接收端的用户设备在检测信号时,可以检测出信号的重复传输配置信息,从而知道所检测信号的重复传输次数和/或重复传输所用的跳频图样。
本申请实施例适用于用户设备进行信号发送与检测的过程,尤其适用于D2D技术中,UE进行信号发送与检测的过程。
本申请实施例中所发送的信号包括但不限于D2D信号,其中,D2D信号包括但不限于D2D发现信号或者D2D通信调度信息。在以下实施例中均以D2D信号作举例。其他信号的发送也是与D2D信号采用同样的方法,在此不再一一赘述。
D2D技术包括D2D发现和D2D通信两种技术。对于D2D发现,用户设备一般在周期性出现的资源池中进行D2D发现信号的发送或者接收。对于D2D通信,用户设备需要发送携带D2D通信调度信息(英文:Scheduling Assignment)的控制信道和相应的数据信道,接收端先接收D2D通信调度信息,再根据D2D通信调度信息来检测相应的数据信道。
在D2D信号收发过程中,用户设备需要知道接收资源区域(该接收资源区域用于其他用户D2D信号的接收),也需要知道发送资源区域(该发送资源区域用于自身D2D信号的发送),由于硬件限制,用户设备无法在一个子帧内同时进行D2D信号的发送和接收。一般情况下,资源区域包括一个子帧集合或者PRB(Physical Resource Block,物理资源块)集合,以及该子帧集合或者PRB集合出现的周期,一个传输周期内可以有若干子帧,每个子帧包含若干PRBs用于传输D2D信号。在每个D2D信号传输周期内,用户设备可以在不发送D2D信号的子帧内都进行其他用户设备的D2D信号的检测。用户设备的发送资源池或者接收资源池在有网络覆盖时一般由基站进行配置,在没有网络覆盖时可以由簇头配置或者预配置在设备中。而且,如果用户设备支持在一个传输周期内或者针对一个数据包进行多次重复传输,以提高传输可靠性,则多次传输所使用的物理资源是关联的,即多次传输的物理资源具有一定的时域或者频域跳频关系。
用户设备传输信号时,首先要确定信号的重复传输配置信息,重复传输配置信息包括重复传输次数和/或重复传输所用的跳频图样。在有了这些信息后就可以确定信号在传输时所使用的物理资源,信号就是在物理资源上传输的。
下面结合说明书附图对本申请实施例做详细描述。
如图1所示,本申请实施例提供的一种信号发送方法的流程图,该方法包括:
步骤101:用户设备确定信号的重复传输配置信息,所述重复传输配置信息包括重复传输次数和/或重复传输所用的跳频图样;
步骤102:所述用户设备将所述重复传输配置信息通过同步信道发送;
步骤103:所述用户设备根据所述重复传输配置信息进行所述信号的发送。
上述流程中,重复传输信号所使用的物理资源具有一定的时域或者频域跳频关系,这种关系可以用跳频图样来描述,跳频图样为时域跳频图样和/或频域跳频图样。
上述流程中,如果没有与接收端约定重复传输次数,需要将重复传输次数作为重复传输配置信息发送,如果没有与接收端约定跳频图样,需要将跳频图样作为重复传输配置信息发送。
步骤101中,重复传输配置信息中所包含的重复传输次数和/或重复传输所用的跳频图样可以有多种方式确定。下面分别详细描述用户设备如何确定重复传输次数和重复传输所用的跳频图样。
较佳的,用户设备采用以下方式之一确定重复传输次数:
方式1:通过接收网络侧配置确定重复传输次数。具体的,用户设备可以通过网络侧设备的广播信息或者专门的高层信令获得重复传输次数的配置信息。
方式2:通过预先配置的方式确定重复传输次数。比如,重复传输次数是预先配置到用户设备中的或者是由协议约定的,用户设备根据该预先配置到该用户设备中的信息获得重复传输次数。
较佳的,用户设备采用以下方式之一确定重复传输信号所用的跳频图样:
方式1:通过接收网络侧设备配置的跳频图样。具体的,用户设备可以通过网络侧设备的广播信息或者高层信令获知跳频图样的配置;或者配置一个用于生成跳频图样的物理层ID,根据该物理层ID获得跳频图样。
方式2:根据预先配置到所述用户设备中的跳频图样来确定。比如,跳频图样是预先配置到用户设备中的或者是由协议约定的,用户设备根据该预先配置到该用户设备中的信息获得跳频图样。
方式3:用户设备自主配置所用的跳频图样。比如,用户设备根据设定的策略配置所用的跳频图样时,用户设备可以随机地从可用的跳频图样中选择所用的跳频图样,或者,用户设备根据一些D2D参数获得跳频图样对应的跳频公式,从而确定所用的跳频图样。比如根据自己的D2D源ID(Source ID)、D2D同步源ID(Synchronization Source ID)、目标ID(Target ID)、通信组ID(Group ID)等D2D相关参数得到跳频图样。
步骤102中,用户设备可通过同步信道发送同步信号进行信道同步。比如,在D2D传输过程中,所述同步信道为物理设备到设备同步信道(Physical Device to Device Synchronization Channel,PD2DSCH)。通常,用户设备在进行信号发送前,首先要进行信道同步。用户设备根据参考同步源发送的同步信号来获得发送信号的同步参考。用户设备发送信号时,也可以同时发送同步信号为其他用户设备提供同步参考,或者同时传输同步信道以传递一些资源配置信息或者同步信息,用于辅助其他用户设备进行同步或者信号的发送或接收。
较佳的,步骤103中,所述用户设备根据所述重复传输配置信息进行信号发送,包括:所述用户设备根据所述重复传输配置信息确定所述信号传输时所使用的物理资源,在所述物理资源上进行所述信号的发送。
较佳的,所述用户设备可根据如下方式之一确定所述信号传输时所使用的物理资源:
方式1:所述用户设备根据所述信号的重复传输配置信息中的重复传输次数以及约定的重复传输所用的跳频图样,确定一个传输周期内除第一次以外的每次重复传输所使用的物理资源。这种方式应用于重复配置信息中包含重复传输次数但不包含重复传输所用的跳频图样的情况。
方式2:所述用户设备根据所述信号的重复传输配置信息中的重复传输所用的跳频图 样以及约定的重复传输次数,确定一个传输周期内除第一次以外的每次重复传输所使用的物理资源。这种方式应用于重复配置信息中不包含重复传输次数但包含重复传输所用的跳频图样的情况。
方式3:所述用户设备根据所述信号的重复传输配置信息中的重复传输次数以及重复传输所用的跳频图样,确定一个传输周期内除第一次以外的每次重复传输所使用的物理资源。这种方式应用于重复配置信息中包含重复传输次数以及重复传输所用的跳频图样的情况。
应当指出的是,上述3种方式中,不仅根据重复传输次数和跳频图样,还结合第一次传输的物理资源确定后续重复传输所用的物理资源。
较佳的,所述用户设备根据网络侧设备配置的信息确定所述一个传输周期内的第一次传输所使用的物理资源;或者,所述用户设备根据设定的策略或预先配置的物理资源确定所述一个传输周期内的第一次传输所使用的物理资源。并在每个传输周期内,在确定的第一次传输所使用的物理资源上进行上述信号的第一次发送。
上述流程中,步骤102中,用户设备还可以将发送资源池信息或者接收资源池信息一起通过同步信道发送。用户设备自主选择物理资源时在发送资源池中选择物理资源,即用户设备选择的物理资源必须在发送资源池的范围内。而接收资源池主要用于网络侧配置物理资源的情况,即用户设备发送信号所用的物理资源由网络侧配置时,用户设备只需要告知接收端的用户设备接收资源池信息。相应地,步骤103中,用户设备根据重复传输配置信息所确定的物理资源是从发送资源池或者接收资源池中选择的。这样,可以一方面,信号发送方用户设备可以根据重复传输配置信息从所述发送资源池或者接收资源池中选择物理资源进行信号发送,另一方面,信号接收方用户设备可根据重复传输配置信息从所述发送资源池或者接收资源池中选择物理资源进行信号检测。
其中,如果一个传输周期内的第一次传输所使用的物理资源是用户设备A自主选择的,例如根据设定的策略或预先配置的物理资源选择的,那么,用户设备A在其发送资源池中,根据设定的策略或预先配置的物理资源确定一个传输周期内第一次传输所使用的物理资源,信号传输时所使用的物理资源;然后,根据重复传输次数、跳频图样以及第一次传输所使用的物理资源,在其发送资源池中确定后续重复传输所使用的物理资源;将重复传输配置信息通过同步信道进行发送,可选的,还将用户设备A的发送资源池信息一起通过同步信道发送;在确定的物理资源上发送信号。
其中,如果一个传输周期内的第一次传输所使用的物理资源是网络侧配置,那么,一个传输周期内的第一次传输所使用的物理资源在用户设备A的接收资源池中,用户设备A根据重复传输次数、跳频图样以及第一次传输所使用的物理资源,在其接收资源池中确定后续重复传输所使用的物理资源;将重复传输配置信息通过同步信道进行发送,可选的, 还将用户设备A的接收资源池信息一起通过同步信道发送;在确定的物理资源上发送信号。
如图2所示,本申请实施例提供的一种信号检测方法的流程图,该方法包括:
步骤201:用户设备通过检测同步信道获得重复传输配置信息,所述重复传输配置信息包括信号的重复传输次数和/或所述信号重复传输所用的跳频图样;
步骤202:所述用户设备根据所述重复传输配置信息进行信号检测。
步骤201中,用户设备检测到发送信号的用户设备在同步信道中的发送的重复传输配置信息,此时用户设备同时也获得了目标用户设备的重复传输配置信息。
这里的目标用户设备可以是:检测到的发送信号的用户设备;或者与检测到的发送信号的用户设备采用相同重复传输配置信息的用户设备;或者与检测到的发送信号的用户设备相同小区的用户设备;或者与检测到的发送信号的用户设备的初始同步源相同的用户设备。
具体的,用户设备从同步信道中获取重复传输配置信息时,也可以获取同步信道中的发送资源池或者接收资源池信息。
步骤202中,用户设备根据所述重复传输配置信息,获得目标用户设备发送的信号的重复传输次数和/或信号重复传输所用的跳频图样,从而确定除第一次传输的信号以外,每次信号重复传输所用的物理资源,从而在相应物理资源上进行信号的检测。
较佳的,所述用户设备根据所述重复传输配置信息确定所述信号重复传输所使用的物理资源;
所述用户设备在所述物理资源上进行所述信号的检测。
用户设备采用以下方式之一确定检测的信号所用的物理资源:
当重复传输配置信息只包含重复传输次数时,用户设备根据重复传输配置信息,获得目标用户设备的信号重复传输次数,并基于约定好的重复传输所用的跳频图样,确定一个传输周期内除第一次传输信号以外,每次信号重复传输所用的物理资源,从而在相应物理资源上进行信号的检测。
当重复传输配置信息只包含重复传输所用的跳频图样时,用户设备基于网络侧配置或者约定好的信号重复传输次数,根据所述重复传输配置信息中的重复传输所用的跳频图样,确定一个传输周期内除第一次传输信号以外,每次信号重复传输所用的物理资源,从而在相应物理资源上进行信号的检测。
当重复传输配置信息包含重复传输次数和重复传输所用的跳频图样时,用户设备根据所述重复传输配置信息中的信号重复传输次数和重复传输所用的跳频图样,确定一个传输周期内除第一次传输信号以外,每次信号重复传输所用的物理资源,从而在相应物理资源上进行信号的检测。
以上方法中,用户设备根据重复传输配置信息确定各次传输所用的物理资源时,信号 第一次传输所用的物理资源可以由网络侧设备配置,或者用户设备将所有可能用于传输目标用户设备信号的物理资源都作为第一次信号传输所用的物理资源。应当指出的是,不仅根据重复传输次数和跳频图样,还结合第一次传输的物理资源确定后续重复传输所用的物理资源。
较佳的,所述用户设备确定一个传输周期内除第一次以外的每次重复传输所使用的物理资源之前,还包括:
所述用户设备根据网络侧设备配置的信息确定所述信号在所述一个传输周期内的第一次传输所使用的物理资源;或者
所述用户设备将发送资源池中每个物理资源均确定为所述信号在所述一个传输周期内的第一次传输所用的物理资源。
用户设备可以结合重复传输配置信息以及同步信道中携带的发送资源池或接收资源池信息,确定关联检测目标用户设备信号的物理资源。比如,重复传输所用的所有物理资源都是在发送资源池或者接收资源池内选择的。
用户设备根据检测到的目标用户设备信号的物理资源,进行目标用户设备信号的关联检测。具体的,用户设备可以将多次重复传输对应的多个物理资源上检测到的信号进行合并后再进行解调。合并解调可以是将对不同物理资源上的信号直接进行合并后解调,也可以是对不同信号进行检测后得到各个信号的软比特信息,再将软比特信息进行合并后解调。
本申请实施例中所检测的信号包括但不限于D2D信号,其中,D2D信号包括但不限于D2D发现信号或者D2D通信调度信息。其他信号的检测也是与D2D信号的检测采用同样的方法,在此不再一一赘述。
下面以D2D发现信号或D2D通信调度信息为例,详细描述D2D发现信号发送和检测的具体流程。
实施例一:
发送端的用户设备接收网络侧设备通过广播信息通知的D2D发现信号的重复传输次数。具体的,网络侧设备可以通过SIB(System Information Broadcast,系统信息广播)中的1比特信息通知发送端的用户设备当前的D2D发现信号重复传输次数是1还是2,假设当前指示的重复传输次数是2。
发送端的用户设备通过1比特信令指示当前D2D发现信号的重复传输次数,并通过PD2DSCH发送;
发送端的用户设备根据网络侧指示的重复传输次数,基于约定好的重复传输所用的多个传输资源之间的跳频图样,得到D2D发现信号在每次重复传输时所用的物理资源,从而在相应的物理资源上进行D2D发现信号的发送。具体的,发送端的用户设备通过如下方式 确定两次重复传输所用的物理资源:第一次传输所用的物理资源由网络侧设备通过专属高层信令配置,第二次传输所用的物理资源通过固定的跳频图样得到。比如,跳频图样可以是:
PRB(2)=[PRB(1)+P]mod nRB
SF(2)=[SF(1)+1]mod nSF
其中,PRB(1)、PRB(2)分别是两次传输所用的频域资源,SF(1)、SF(2)分别是两次传输所用的时域资源,nRB,nSF为发送资源池总的频域和时域资源数,P为约定好的固定值,这里假设为0,即多次重复传输所用的物理资源为连续子帧的相同PRB资源。
接收端的用户设备检测发送端的用户设备的PD2DSCH中的信息,从PD2DSCH中获取发送端的用户设备的D2D发现信号的重复传输次数信息,从而确定目标用户设备(即与发送端的用户设备同小区的所有用户设备)的信号的重复传输次数;
接收端的用户设备获知目标用户设备的D2D发现信号的重复传输次数后,基于约定好的重复传输所用的多个传输资源之间的跳频图样,确定各次重复传输所用的发现资源,作为关联检测目标用户设备的D2D发现信号的物理资源。具体的,用户设备将网络侧指示的接收资源池中的所有资源都确定为候选的第一次传输发现资源,对应的第二次传输所用的发现资源通过上述跳频图样得到,即多次传输的D2D发现信号占用连续子帧中相同PRB资源。
接收端的用户设备在候选多次重复传输所用的物理资源上关联检测发送端用户设备所在小区各用户设备的发现信号。接收端的用户设备在盲检过程中,对重复传输所用的两个物理资源进行关联检测,即连续子帧的相同PRB资源上检测到的信号或者信息进行合并后再进行解调,并用此方法依次对所有候选发现资源进行盲检,检测出发送端用户设备所在小区各用户设备的发现信号。
实施例二:
发送端用户设备从发送资源池中候选的跳频图样中随机选择一个跳频图样,作为D2D通信调度信息重复传输所用的多个传输资源之间的跳频图样;
发送端用户设备将跳频图样的信息通过同步信道发送。具体的,发送端用户设备将选择的跳频图样在候选跳频图样中对应的索引,以及发送端用户设备发送D2D通信调度信息所用的发送资源池信息通过PD2DSCH发送;
发送端用户设备基于预先约定好的信号重复传输次数,比如固定在协议中的次数,这里假设重复传输次数为2,根据信号重复传输所用的多个传输资源之间的跳频图样确定两次重复传输所用的物理资源,从而在相应物理资源上进行D2D通信调度信息的发送。具体的,发送端用户设备从发送资源池中根据自身的D2D ID得到一个物理资源作为第一次传输D2D通信调度信息所用的物理资源,第二次重复传输所用的物理资源通过第一次传输所 用的物理资源和前面确定的跳频图样得到,且需要保证第二次传输的物理资源也在D2D通信调度信息所用的发送资源池内。
接收端用户设备检测发送端用户设备的PD2DSCH中的信息,根据其中的跳频图样索引获知发送端用户设备的D2D通信调度信息重复传输所用跳频图样,并获知发送端用户设备的发送资源池信息。
接收端用户设备基于预先约定好的信号重复传输次数(这里约定的为2),根据获知的发送端用户设备的D2D通信调度信息的重复传输所用的跳频图样,确定各次重复传输所用的物理资源,作为关联检测发送端用户设备的D2D通信调度信息的物理资源。具体的,接收端用户设备将得到的发送端用户设备的发送资源池中的每个资源都确定为候选的第一次传输物理资源,对应的第二次传输所用的物理资源通过第一次传输物理资源和上述确定的跳频图样得到。
接收端用户设备在候选的第一次传输物理资源和对应的重复传输物理资源上关联检测发送端用户设备的信号。具体的,接收端用户设备将两次重复传输对应的物理资源上检测到的信号或者信息进行合并后再进行解调,并依次检测各候选的物理资源。
实施例三:
发送端用户设备确定自身的D2D信号的重复传输次数和信号重复传输所用的多个传输资源之间的跳频图样。具体的,发送端用户设备通过网络侧发送的1比特高层信令获知重复传输次数的配置为4,并根据自身的同步源ID确定D2D信号重复传输所用的多个传输资源之间的跳频图样。确定方法如下:(预先约定好)
PRB(2)=[PRB(1)+P]mod nRB
SF(2)=[SF(1)+K]mod nSF
其中,PRB(1),PRB(2)分别是两次传输所用的频域资源,SF(1),SF(2)分别是两次传输所用的时域资源,nRB,nSF为发送资源池总的频域和时域资源数,P根据发送端用户设备的D2D ID得到,K为约定好的固定值。
发送端用户设备将上述确定的重复传输配置信息通过同步信道发送。具体的,发送端用户设备将指示重复传输次数的2比特信息、用于确定跳频图样的发送端用户设备的同步源ID,以及发送端用户设备发送D2D信号所用的发送资源池信息通过同步信道发送;
发送端用户设备基于确定的信号重复传输次数(这里假定为4),根据信号重复传输所用的跳频图样确定四次重复传输所用的物理资源,从而在相应资源上进行D2D信号的发送。具体的,信号第一次传输所用的物理资源由用户设备从发送资源池中随机选择,其他重复传输所用的物理资源通过第一次随机选择的物理资源和上述跳频图样得到,跳频图样中的nRB,nSF由发送端用户设备的发送资源池大小确定。
接收端用户设备检测发送端用户设备的同步信道中的信息,根据其中的重复传输次数 指示信息获知发送端用户设备信号的重复传输次数,根据其中的发送端用户设备的同步源ID确定重复传输所用的多个传输资源之间的跳频图样,并获知发送端用户设备的发送资源池信息。
