背景技术
在LTE(Long Term Evolution,长期演进)系统中基于PC-5接口的车辆之间的直接通信中,如何准确地获得数据传输占用资源的能量或者功率,可以有效地辅助车联网中的资源分配。
当前,一种获得数据传输占用资源的能量或者功率的方法是:通过与数据传输资源关联的SA(Scheduling assignment,调度分配)信息进行能量测量,并将能量测量的结果标识为对应的数据传输资源的能量。这种方法主要的好处是简单。但是,由于SA信息发送功率有可能与数据Data发送的功率不同,并且数据传输占用的频域资源的大小在每次传输的时候有可能不同,因此会造成标识的数据传输占用资源的能量与实际的数据传输占用资源的能量有比较大的偏差,从而影响数据传输资源的分配,造成资源调度的不准确。

需要说明的是,这些界定的名词并不能限制本公开文本的保护范围,根据实际情况,可进行适当的调整。
在此,预先说明的是,当接收功率或能量与其他的对象并列时,表示接收功率或能量中的一个和其他的对象的并列,如根据接收功率或能量和预设策略进行资源选择表示的含义是:
根据接收功率和预设策略进行资源选择;或者
根据能量和预设策略进行资源选择。
参见图5所示,本公开文本实施例提供一种资源调度方法,用于为第一移动通信终端分配传输资源,包括如下步骤:
步骤51,接收第二移动通信终端发送的调度分配信息;
步骤52,根据所述调度分配信息确定所述第二移动通信终端需要占用并用于数据传输的第一时频传输资源;
步骤53,确定所述第一移动通信终端在所述第一时频传输资源的每一个时频传输资源单位上的第一接收功率或能量;
步骤54,根据所述第一接收功率或能量为所述第一移动通信终端调度用于数据传输的目标时频传输资源。
相对于相关技术的以SA信息的接收功率或能量来进行调度的方式而言,本公开文本具体实施例通过用于数据传输的时频传输资源单位上的接收功率或能量来调度用于数据传输的第二时频传输资源,能够提高标识的数据传输占用资源的能量的精度,减少与实际的数据传输占用资源的能量的偏差,提高资源调度的准确性。
其中,所述时频传输资源单位为子带或物理资源块PRB,通过确定每一个时频传输资源单位上的接收功率或能量。
目前,在LTE-based V2V(Vehicle to Vehicle,车辆到车辆)技术中,确定采用基于LTE D2D(Device to Device,设备到设备)的方式进行改进,其中属于控制信息的调度分配(SA)信息与数据信息(Data)是通过不同的信 道进行传输,接收端通过检测控制信道中携带的SA信息,再根据SA信息中携带的信息进行数据信息的接收。而在进行资源选择时,可存在两种方式,一种为用户设备UE自发进行,另一种为基站辅助进行。
相应地,参见图6A和图6B所示,本公开文本实施例中,所述资源调度方法可由第一移动通信终端执行,所述第一移动通信终端根据收集到的信息自发地为自身分配传输资源,所述资源调度方法也可由基站E-UTRAN(Evolved UMTS Terrestrial Radio Access Network,演进的UMTS(Universal Mobile Telecommunications System,通用移动通信系统)陆地无线接入网)执行,所述基站通过收集到的信息为第一移动通信终端分配传输资源,并将分配结果下发至所述第一移动通信终端。
具体地,当所述资源调度方法由基站执行时,在所述基站调度到目标时频传输资源后,会下发包括所述目标时频传输资源的位置信息的授权信息(例如V2Vgrant信息)至所述第一移动通信终端,以使所述第一移动通信终端完成传输资源的选择,进行数据传输。
本公开文本实施例中,在通过SA的接收功率或能量的测量结果来获取数据传输占用资源的接收功率或能量时,参见图7所示,所述步骤53具体包括:
步骤71,获取所述第一移动通信终端在承载所述调度分配信息的第二时频传输资源上的第二接收功率或能量;
步骤72,根据所述第二接收功率或能量确定所述第一接收功率或能量;
其中,所述第一接收功率或能量为所述第二接收功率或能量与A1/K1的乘积,所述A1为所述第二移动通信终端发送数据时的第一发射功率或能量与发送所述调度分配信息的第二发射功率或能量的比值;
所述K1为所述第一时频传输资源所包括的时频传输资源单位的数量。
下面,通过具体实例对上述功率或能量确定步骤进行详细说明。其中,下面实例均是以功率确定为例来说明的,但同样适用于能量确定。
在一些实例中,参见图2所示,当SA和Data的传输位于不同的子帧时,第一移动通信终端UE0在接收到其他移动通信终端UE′发送的SA信息的时候,数据的传输还没有发生,因此只能通过SA的接收功率测量结果来标识 在后续数据传输占用的时频传输资源的接收功率。同时,在SA接收成功的情况下,从SA信息中可以获取关联的数据传输占用的PRB个数。
假设,SA的传输占用N个PRB,而关联的数据传输占用K个子带(时频传输资源单位),每个子带包含M个PRB,UE0接收到UE′的SA的功率测量的结果为P_sa(第二接收功率),对应的数据传输占用的时频传输资源的(以M个PRB(即子带)为粒度)的功率为P_data_subband(第一接收功率)。
情况一:SA传输与数据传输分配相同的功率
其中,该情况一例如为SA传输与数据传输都是以UE′的全部功率进行发送,即A1=1,K1=K。那么,可以得到:
UE0在数据传输所占用的资源上接收的总的功率为P_data=P_sa,而在每个子带上接收的功率就为P_data_subband=P_data/K=P_sa/K,即:
P_data_subband=P_sa*A1/K1。
情况二:SA传输和关联的数据传输之间发送的功率是不相的
其中,该情况二例如为SA发送功率与数据发送功率之间的比值是a∶1,即A1=1/a,K1=K。那么,可以得到:
UE0在数据传输所占用的资源上接收的总的功率为P_data=P_sa/a,而在每个子带上接收的功率就为P_data_subband=P_data/K=P_sa/(a*K),即P_data_subband=P_sa*A1/K1。
这种情况下,需要通过信令指示SA发送功率和data发送功率之间的偏差,而所述信令可以通过SA携带,也可以通过高层信令配置。
在一些实例中,参见图3所示,SA和数据的传输位于相同的子帧,其中在数据传输占用的时频传输资源上的接收功率可以通过接收到的SA的功率测量结果获得。
假设,SA的传输占用N个PRB,而关联的数据传输占用K个子带,每个子带包含M个PRB,UE0接收到UE′的SA的功率测量的结果为P_sa(第二接收功率),在对应的数据传输占用资源(以M个PRB(即子带)为粒度)上的接收功率为P_data_subband(第一接收功率)。
情况一:SA传输与数据传输采用按照PRB等功率分配的方法
这种情况下,SA发送功率与数据发送功率之间的比值N/(M*K),即 A1=(M*K)/N,K1=K,其处理过程如下所述:
计算每个PRB上的SA的接收功率为P_sa_rb=P_sa/N;
计算传输数据的时频传输资源中,在每个子带上的接收功率如下:
P_data_subband=P_sa_rb*M=P_sa*M/N。
即:
P_data_subband=P_sa*A1/K1。
情况二:SA传输和关联的数据传输的发送功率不同
假定用于SA传输的PRB上的发送功率与用于数据传输的PRB上的发送功率的比值是a∶1,则SA发送功率与数据发送功率的比值为:(a*N)/(M*K),则:
A1=(M*K)/(a*N)
K1=K。
由此可以得到:
传输SA的PRB上的接收功率P_sa_rb为P_sa/N,而传输数据的PRB上的接收功率P_data_rb为P_sa_rb/a,则传输数据的子带上接收的功率P_data_subband为P_data_rb*M=P_sa*M/(N*a),即:
P_data_subband=P_sa*A1/K1。
这种情况下,需要通过信令指示传输SA的PRB上的发送功率和传输数据的PRB上的发送功率之间的偏差,而所述信令可以通过SA携带,也可以通过高层信令配置。
本公开文本实施例中,当所述第一时频传输资源与承载所述调度分配信息的第二时频传输资源在同一子帧时,还可直接获取数据传输占用资源的接收功率或能量,具体地,参见图8所示,所述步骤53具体包括:
步骤81,检测所述第一移动通信终端在所述第一时频传输资源上的第三接收功率或能量;
步骤82,根据所述第三接收功率或能量确定所述第一接收功率或能量;
其中,所述第一接收功率或能量为第三接收功率/K1,所述K1为所述第一时频传输资源所包括的时频传输资源单位的数量。
举例来说,参见图3所示,SA和数据的传输位于相同的子帧。假设,SA 的传输占用N个PRB,而关联的数据传输占用K个子带,每个子带包含M个PRB,终端在数据传输所占用的资源上的总接收功率为P_data(第三接收功率),则在传输数据的PRB上的接收功率P_data_rb为:P_data/(K*M)。
因此传输数据在子带上的接收功率P_data_subband为:P_data_rb*M=P_data/K,即P_data_subband=P_data/K1。
具体地,如图4所示,SA传输和数据传输位于相同的子帧,但是SA中既包含当前数据传输的资源指示,也包含下一次传输的资源指示,其中相同标识区域数据传输表示的是对同一数据的初传和重传。其中,UE0总是希望根据当前子帧的测量,获取当前SA信息中指示的下一次数据传输的功率,例如如图4所示的虚线框所指的子帧41中,SA指示的当前子帧中数据传输占用的第一资源42中的子带的个数与下一次数据传输占用的第二资源43中的子带的个数是不同的,因此也需要根据在当前子帧测量到的,传输数据在子带上的接收功率P_data_subband_1来确定下一次传输数据在子带上的接收功率P_data_subband_2。如果当前子帧中的数据传输占用的子带个数为K1,下一次数据传输占用的子带个数为K2,那么P_data_subband_2=P_data_subband_1*K1/K2。
本公开文本实施例中,参见图9所示,所述步骤54具体包括:
步骤91,根据所述第一移动通信终端在所述第一时频传输资源的每一个时频传输资源单位上的第一接收功率或能量和预定策略选择目标子帧;
步骤92,获取所述第一移动通信终端在承载所述目标子帧对应的所述调度分配信息的第三时频传输资源上的第三接收功率或能量;
步骤93,根据第三接收功率或能量确定所述目标子帧中每一个时频传输资源单位是否可用;
步骤94,根据所述目标子帧中每一个时频传输资源单位是否可用的信息调度所述目标时频传输资源。
在UE自发的选择资源的方式中,UE需要感知资源的占用情况,从而进行资源的选择,通常来说有两种方式:一种是根据接收到的其它UE的SA信息,获知其它UE的数据传输占用的资源指示,从而在未被占用的传输资源中选择传输的资源;另一种是直接在数据传输的资源上进行功率检测,如果 功率高于一定的门限,那么认为对应的传输资源是被占用的,在此基础上,选择未被占用的传输资源进行数据的传输。在第一种方式中,如果数据传输与关联的SA的传输位于同一子帧,那么UE需要根据当前的感知确定后续一段时间内资源是否被占用,因此需要知道数据传输持续占用的时间或者周期,从而确定未来一段时间内的传输资源的占用情况,同理对于基于传输资源的能量检测,也需要知道数据传输持续占用的时间或者周期,从而确定未来一段时间内的传输资源的占用情况。
简单来说,如图1所示,UE需要根据能量检测或者SA的检测以及数据传输持续占用资源的时间或者周期来构建未来一定数量的子帧的资源占用情况,从而在选择空闲的资源进行传输。图1中标识了UE1、UE2和UE3传输资源占用的情况,UE4如果需要进行数据传输,可以在空闲的资源中选择资源。或者进一步的可以通过SA检测或能量检测的方式获知哪个子帧上的干扰小(即子帧中对应的接收功率或能量的和值小),并结合预定策略,选择一个或多个干扰较小的目标子帧。其中,所述预定策略例如为选择两个、三个或四个等目标子帧。例如,在图1中,UE4可以选择第一个子帧和最后一个子帧(虚线所框的子帧)进行传输资源的传输。
在确定能量分布之后,如何选择目标子帧可以有多种方式,如选择功率和最小的子帧,也可以按照功率和从小到大的顺序,选择多个子帧,而选择的子帧的数量可以预先确定,也可以根据功率和超过预定门限的子帧数量来确定,在此不一一描述。
本公开文本实施例中,当所述第三时频传输资源与所述第三时频传输资源承载的调度分配信息所指示的第四时频传输资源在同一子帧时,所述第三接收功率或能量为:第四接收功率或能量与A2的比值;
其中:所述第四接收功率或能量为所述第一移动通信终端在所述第四时频传输资源上的接收功率或能量;
所述A2为所述第二移动通信终端在所述第四时频传输资源的发射功率或能量与所述第二移动通信终端在所述第三时频传输资源上的发射功率或能量的比值。
上述方式中,通过数据的接收功率检测结果来获取SA的接收功率能够 得到更加准确的SA接收功率结果,原因如下。
相对而言,数据所占用的资源远大于SA所占用的资源,因此接收端对数据的接收功率结果会更加准确或者说误差更小,而利用误差更小的检测结果进行计算得到的SA接收功率会更加准确。
相关技术中,在资源分配中终端可以根据SA接收的能量或功率,来判断当前接收到的SA指示的传输资源是否属于需要有效规避的传输资源。例如设定一个SA的功率门限,如果接收到的SA的功率高于所述功率门限,那么认为接收的SA指示的传输资源是需要进行规避的传输资源,否则认为接收的SA指示的传输资源是空闲的。
上述机制在负载比较高的时候,可以有效地提高资源分配的效率。但由于SA和数据传输可能位于相同子帧,也可能位于不同子帧,而在SA和数据传输位于相同子帧的情况下,数据传输占用的频域资源的大小都会发生变化,同时还有各种信道衰落的影响等,这些都会影响SA的接收能量,从而导致使用一个统一的门限无法进行正确的判别。
对此举例如下。
当SA和数据在不同子帧传输时,SA可以独占所有的发射功率,而当SA和数据在同一子帧传输时,SA需要和数据共享发射功率,在这两种情形下,依据SA的接收功率进行资源是否占用的判断,使用同一门限很明显是不合理的。所以,本公开文本实施例中,可对目标子帧对应的SA信息进行划分,例如划分为第一模式的SA信息(对应在同一子帧情况)和第二模式的SA信息(对应不在同一子帧情况),并统一进行SA的能量归一化处理(把不同的情形统一到一个统一的标准下进行考量),以减小所述目标子帧对应的所述SA信息由于模式差异导致的接收功率或能量的差异。
具体地,本公开文本实施例中,所述目标子帧对应的所述调度分配信息包括:
第一模式的调度分配信息,所在的第五时频传输资源和所指示的时频传输资源在同一子帧;和
第二模式的调度分配信息,所在的第六时频传输资源和所指示的时频传输资源不在同一子帧。
相应地,参见图10所示,所述步骤93具体包括:
步骤101:计算同一中间场景中,第一模式的调度分配信息的第五接收功率或能量对应的第七功率或能量,以及第二模式的调度分配信息的第六接收功率或能量对应的第八功率或能量;
换句话说,本公开文本具体实施例中,步骤101中,对所述第一移动通信终端在所述第五时频传输资源上的第五接收功率或能量和在所述第六时频传输资源上的第六接收功率或能量进行转换,得到转换后的接收功率或能量,减小了所述目标子帧对应的所述调度分配信息由于模式差异导致的接收功率或能量的差异;
步骤102:利用转换得到的第七接收功率或能量以及第八接收功率或能量确定所述目标子帧中每一个时频传输资源单位是否可用。
具体地,对所述第五接收功率或能量进行转换得到的接收功率或能量为:
第五接收功率或能量*N/(N+M);
对所述第六接收功率或能量进行转换得到的接收功率或能量为:
(1+A3)*第六接收功率或能量*N/(N+M);或者
(1+1/A3)*第七接收功率或能量*N/(N+M);
其中,所述N为预设的所述调度分配信息占用的时频传输资源单位数量,所述M为预设的数据传输占用的时频传输资源单位数量,A3为所述第二移动通信终端发送数据的发射功率或能量与发送所述第二模式的调度分配信息的发射功率或能量的比值,所述第七接收功率或能量为所述第一移动通信终端在所述第二模式的调度分配信息所指示的时频传输资源上的接收功率或能量。
这样,利用SA接收能量的归一化结果进行门限判断,如果高于SA接收门限,则表示当前SA信息中指示的数据传输的资源在后续一段时间或者按照一定的周期持续占用,否则数据传输的资源认为是空闲的,可有效提高资源分配的性能。
下面,通过具体实例对SA的能量归一化处理进行说明。
这里,SA功率归一化的基准为:SA占用N个PRB,数据传输占用一个子带(M个PRB,即预设的数据传输占用的时频传输资源单位数量)的情况 下,SA和数据的发送基于PRB等功率分配。
在一些实例中,SA和关联数据位于不同子帧,并假定SA和数据采用等功率发送,归一化的处理可以采用将SA的接收的总功率按PRB的个数等功率的分散在SA占用的N个PRB和数据传输占用的M个PRB(一个子带)中,然后计算N个PRB上的SA的接收功率,归一化之后的SA功率为:P_sa*N/(N+M)。
在一些实例中,SA和关联数据位于相同子帧,SA占用N个PRB,数据传输占用K个子带,每个子带包含M个PRB,并假定SA和数据传输按照PRB等功率分配,即A3=(K*M)/N,归一化的处理可以分为以SA功率测量结果P_sa为基础的归一化处理或者以P_data_subband为基础的归一化处理。
具体过程详细说明如下。
以SA能量测量P_sa为基础的归一化处理过程包括如下步骤:
根据P_sa,计算传输SA的PRB上的接收功率P_sa_rb为:P_sa/N;
由于传输数据的PRB上的发送功率与传输SA的PRB上的发送功率相同的,所以,传输SA的PRB上的接收功率P_data_rb与传输数据的PRB上的接收功率P_data_rb也相同,即P_sa_rb等于P_data_rb;
在当前子帧SA和数据的总接收功率为P_sa_rb*(N+K*M)=(1+A3)*P_sa;
归一化的SA接收功率的结果为:(1+A3)*P_sa*N/(N+M)。
以P_data_subband为基础的归一化处理过程包括如下步骤:
根据传输数据在子带上的接收功率P_data_subband计算传输数据在PRB上的接收功率P_data_rb为:P_data_subband/M;
由于传输数据的PRB上的发送功率与传输SA的PRB上的发送功率相同的,所以,传输SA的PRB上的接收功率P_data_rb与传输数据的PRB上的接收功率P_data_rb也相同,即P_sa_rb等于P_data_rb;
当前子帧SA和数据的总接收功率为P_data_rb*(N+K*M)=(1+A3)*P_sa;
归一化的SA接收功率的结果为:(1+A3)*P_sa*N/(N+M)。
在一些实例中,SA和关联数据位于相同子帧,SA占用N个PRB,数据传输占用K个子带,用于SA传输的PRB上的发送功率与用于数据传输的PRB上的发送功率的比值是a∶1,以P_data_subband为基础的归一化处理过程包括 如下步骤:
根据传输数据在子带上的接收功率P_data_subband计算传输数据在PRB上的接收功率P_data_rb为:P_data_subband/M;
用于SA传输的PRB上的发送功率与用于数据传输的PRB上的发送功率的比值是a∶1,所以,传输SA的PRB上的接收功率P_sa_rb等于a*P_data_rb;
在当前子帧SA和数据的总接收功率为P_data_rb*K*M+P_sa_rb*N=(1+A3)*P_sa;
归一化的SA接收功率的结果为:(1+1/A3)*P_data*N/(N+M)。
其中,当以SA功率测量结果P_sa为基础的归一化处理过程基本一致,在此不再重复描述。
本公开文本实施例中,根据对目标子帧的分析,当所述目标子帧中的时频传输资源单位对应的调度分配信息的接收功率或能量(可以是原始的接收功率或能量,也可以是转换后的接收功率或能量)大于或等于预定门限时,所述时频传输资源单位不可用,否则所述时频传输资源单位可用。
其中,所述预定门限可根据实际情况进行确定,本公开文本不对其进行限制。
