图3为本公开实施例的网络设备的结构框图;
图4为本公开实施例的网络设备的模块示意图;
图5为本公开实施例的终端的结构框图;
图6为本公开实施例的终端的模块示意图。
为使本公开要解决的技术问题、技术方案和优点更加清楚,下面将结合附图及具体实施例进行详细描述。
如图1所示,为本公开实施例提供的一种信号传输方法的流程示意图,应用于网络设备,包括:
步骤101:配置至少一个发送波束;所述发送波束为节能信号的传输资源对应的波束;
这里,网络设备为每个节能信号的传输资源均配置至少一个发送波束beam,即配置一个或者多个发送beam。
需要说明的是,节能信号的传输资源具体是指节能信号的发送资源。
这里,节能信号的发送资源是指发送节能信号的时间与频率,但也不排除其他资源,如码分资源和空间资源。
步骤102:在所述至少一个发送波束上,发送所述节能信号。
本步骤中,具体的,通过与节能信号对应的传输资源,在至少一个发送波束上发送该节能信号。
本公开实施例的信号传输方法,通过配置至少一个发送波束;所述发送波束为节能信号的传输资源对应的波束;在所述至少一个发送波束上,发送所述节能信号,如此,能够实现基于波束的节能信号的传输,保证后续终端能够根据接收到的节能信号的指示执行相应的事件,达到节省终端电量的目的。
基于图1所示的实施例,作为一较佳地实现方式,步骤101可包括:
通过高层信令或者物理层信令,配置一个发送波束。
本步骤中,具体的,通过高层信令或者物理层信令,为节能信号的传输资源配置一个发送beam。
其中,较佳地,网络设备(如基站)可通过RRC(Radio Resource Control,无线资源控制)信令半静态配置或者预先约定的方式为终端静态配置终端专用UE specific或者终端组专用UE group specific的节能信号的发送资源,之后,通过RRC信令为该节能信号配置一个发送beam。较佳地,该节能信号为基于序列的节能信号。当然,也不排除其他形式的节能信号。
基于图1所示的实施例,作为一较佳地实现方式,步骤101可包括:
通过高层信令或者物理层信令,配置至少两个发送波束。
本步骤中,具体的,通过高层信令或者物理层信令,为节能信号的传输资源配置至少两个发送beam,也就是多个发送beam。
基于图1所示的实施例,作为一较佳地实现方式,步骤101可包括:
配置至少两个传输资源,所述传输资源为所述节能信号对应的资源;
本步骤中,具体的,通过高层信令,配置至少两个传输资源。
为每个所述传输资源配置至少一个发送波束。
这里,高层信令可包括高层RRC信令或MAC CE。
当然,还可通过物理层信令,配置至少两个传输资源。这里,物理层信令可包括物理层PDCCH信令。
需要说明的是,网络设备可以先配置多个传输资源,配置完该多个传输资源后,再分别为该多个传输资源中的每个传输资源配置至少一个发送beam。
网络设备还可以配置一个传输资源A,配置完该传输资源A后,再为该传输资源A配置至少一个发送beam;接着,再配置一个传输资源B,配置完该传输资源B后,再为该传输资源B配置至少一个发送beam,依次类推,直至配置完成n个传输资源,且为每个传输资源配置至少一个发送beam。
进一步地,所述节能信号为基于物理下行控制信道PDCCH的节能信号,所述方法还可包括:
为所述发送波束配置参考信号,其中,不同的发送波束对应不同的参考信号。
具体的,所述不同的发送波束对应不同的参考信号包括以下中的一项:
不同的发送波束对应的参考信号的序列相同,图样不同;
不同的发送波束对应的参考信号的序列不同,图样相同;
不同的发送波束对应的参考信号的序列不同,且图样不同。
需要说明的是,若参考信号的序列与波束信息相关,这里,不同的发送波束对应的参考信号的序列不同,可以是与参考信息的序列相关的波束信息不同,具体的,可以是产生参考信号的序列的gold序列的初始相位中包含的波束索引beam index信息不同。
在一示例中,节能信号为基于PDCCH的节能信号,网络设备为该节能信号的传输资源,即CORESET配置多个发送beam,并为不同的发送beam配置不同的DRMS(Demodulation Reference Signal,解调参考信号),也就是说,不同的发送beam之间所配置的DRMS不同,具体的,可以是不同的发送beam之间所配置的解调参考信号图样DRMS pattern不同。
这里,一般地,发送beam可包括多个聚合等级,其中,不同的聚合等级之间所配置的DRMS pattern不同。
基于图1所示的实施例,作为一可选地实现方式,步骤102可包括:
从所述至少一个发送波束中选择一目标发送波束;
本步骤中,具体的,网络设备可根据终端的信道传输质量,从所述至少一个发送波束中选择一目标发送波束。
比如,网络设备获取终端上报的终端所处的信道环境的信道传输质量,网络设备根据终端的信道传输质量,从所述至少一个发送波束中选择一与终端的信道传输质量相适应的目标发送波束。
这里,与终端的信道传输质量相适应的目标发送波束,也就是目标发送波束能够使网络设备发送的节能信号以较佳的信号质量到达终端的接收机的方向。
在所述目标发送波束上发送所述节能信号。
基于网络设备通过高层信令或者物理层信令,配置至少两个发送波束的实施例,作为一可选地实现方式,步骤102可包括:
在至少两个第一时间单元上,通过所述至少两个发送波束中相同的发送波束发送所述节能信号。
本步骤中,利用相同的发送波束在多个位置(较佳的,多个第一时间单元)上发送节能信号。
比如,网络设备(如基站)在得到终端上报的信道质量信息时,网络设备可以利用在至少两个发送波束中选定的发送波束(即相同的发送波束)在多个第一时间单元上发送节能信号。这样,能够使网络设备发送的节能信号以较佳的信号质量到达终端的接收机的方向。
作为又一可选地实现方式,步骤102可包括:
在至少两个第一时间单元上,分别通过所述至少两个发送波束中不同的发送波束发送所述节能信号,不同的第一时间单元对应不同的发送波束。
本步骤中,不同的第一时间单元对应不同的发送波束,也就是说,第一时间单元与发送波束之间具有对应关系。
比如,网络设备(如基站)在未得到终端上报的信道质量信息时,网络设备可以利用在至少两个发送波束中不同的发送波束发送节能信号,这样,至少能够保证终端接收到节能信号。
基于网络设备配置至少两个传输资源,所述传输资源为所述节能信号对应的资源;为每个所述传输资源配置至少一个发送波束的实施例,作为一可选地实现方式,所述方法还可包括:
配置至少两个第二时间单元,不同的第二时间单元对应不同的传输资源。
本步骤中,具体的,通过高层信令、物理层信令或者预先约定,配置至少两个第二时间单元。
比如,通过高层RRC信令或MAC CE或者预先约定,配置每个传输资源对应的节能信号的发送时间单元(即第二时间单元)。
基于此,进一步地,步骤102可以包括:
在至少两个第二时间单元上,且在所述至少两个第二时间单元各自对应的传输资源上,通过与所述传输资源对应的至少一个发送波束发送所述节能信号。
需要说明的是,由于基站在不同传输资源上的发送波束不同,第二时间单元为通过发送波束发送节能信号的时间与网络设备波束切换的时间之和。也就是说,第二时间单元除了包括通过发送波束发送节能信号的时间外,还包括预留出的网络设备波束切换的时间。
一般地,第二时间单元的时间大于上述实施例中的第一时间单元的时间。
在一示例中,当节能信号为基于PDCCH的节能信号时,网络设备(如基站)为基于PDCCH的节能信号配置T个控制资源集CORESET,并为每个CORESET配置W个发送beam,W≥1,且W为正整数。
网络设备可依次在不同的第二时间单元,在不同CORESET上通过各自对应的发送波束发送相同的节能信号。
比如,T=2or 3,W=1,网络设备可以预先定义每个发送时间单元(即第二时间单元)为K个OFDM符号,每个K个OFDM符号,网络设备在一个CORESET上通过对应的发送波束发送一次节能信号。
需要注意的是,由于网络设备在不同CORESET上的发送波束不同,K个OFDM符号包括预留出的网络设备波束切换的时间。
当W>1,即每个CORESET上配置的发送波束大于一个时,网络设备在每个发送时间单元,即K个OFDM符号上,依次在当前CORESET对应的W个发送波束上发送节能信号,或者在当前CORESET对应的大于或者等于1且小于W个发送波束上发送节能信号。
需要说明的是,上述在多个CORESET及其对应的多个发送波束上发送的节能信号是相同的节能信号。
进一步地,为了实现上述步骤,并提高终端接收节能信号的准确性,所述方法还包括:
为终端配置用于终端在时间单元上检测发送波束的先验信息,所述时间单元包括第一时间单元或第二时间单元。
具体的,本步骤可具体包括:
通过高层信令、物理层信令或者预先约定,为终端配置用于终端在时间单元上检测发送波束的先验信息。
这里,发送波束的先验信息至少包括但不限于:时间单元与发送波束之间的对应关系。也就是,不同的时间单元对应不同的发送波束,这里,可通过网络设备配置(具体可以是通过RRC信令半静态配置)或者与终端预先约定的静态配置的方式得到。如此,终端可分别针对不同波束进行检测。
本公开实施例的信号传输方法,通过配置至少一个发送波束;所述发送波束为节能信号的传输资源对应的波束;在所述至少一个发送波束上,发送所述节能信号,如此,能够实现基于波束的节能信号的传输,保证后续终端能够根据接收到的节能信号的指示执行相应的事件,达到节省终端电量的目的。
如图2所示,为本公开实施例提供的信号传输方法的流程示意图,应用于终端,包括:
步骤201:接收网络设备在至少一个发送波束上发送的节能信号。
本步骤中,至少一个发送波束beam包括一个或多个发送beam。
需要说明的是,网络设备为节能信号对应的传输资源配置至少一个发送beam,配置完成后,可通过高层信令或者物理层信令通知终端。终端获知网络设备配置的至少一个发送beam,针对每个发送beam,终端都有对应的接收beam。
也就是说,本步骤中,具体的,可通过接收beam,接收网络设备在至少一个发送波束上发送的节能信号。
本公开实施例的信号传输方法,通过接收网络设备在至少一个发送波束上发送的节能信号,如此,能够实现基于波束的节能信号的传输,保证终端能够根据接收到的节能信号的指示执行相应的事件,达到节省终端电量的目的。
基于图2所示的实施例,作为一较佳的实现方式,所述发送波束包括一个发送波束,步骤201可包括:
在与所述发送波束对应的接收波束上,接收所述网络设备在所述发送波束上发送的节能信号。
这里,由于网络设备为节能信号对应的传输资源配置一个发送波束,终端通过网络设备的信令通知获知该发送波束,针对该发送波束,终端具有对应的接收波束。这样,在保证终端在对应该发送波束的接收波束上准确地接收到节能信号的同时,还能够节省资源,降低终端的复杂度。
基于图2所示的实施例,作为一较佳的实现方式,所述发送波束包括至少两个发送波束,所述至少两个发送波束对应相同的节能信号;步骤201之后,所述方法还可包括:
确定网络设备在所述至少两个发送波束中选定的目标发送波束。
需要说明的是,由于终端不知道网络设备在哪个发送波束上发送节能信号,也便无法得知终端能够在哪个接收波束上接收到节能信号,所以为了确定接收到节能信号的接收波束,降低功耗,提升解调解码节能信号的成功率,需要确定网络设备在所述至少两个发送波束中选定的目标发送波束。
基于此,在节能信号为基于PDCCH的节能信号,网络设备为发送波束 配置参考信号的情况下,相应地,作为一可选的实现方式,本步骤,确定网络设备在所述至少两个发送波束中选定的目标发送波束,可具体包括:
对所述发送波束对应的参考信号进行检测,不同的发送波束对应不同的参考信号;
本步骤中,具体的,对每个发送beam对应的基于PDCCH的节能信号的DMRS执行假设检测,较佳的,该检测可利用简单的序列相关性进行。
若检测到参考信号,则确定与所述参考信号对应的发送波束为网络设备在所述至少两个发送波束中选定的目标发送波束。
这里,具体的,若仅检测到一个参考信号,则确定与该参考信号对应的发送波束为网络设备在所述至少两个发送波束中选定的目标发送波束。
若检测到至少两个参考信号,则确定所述至少两个参考信号中目标参考信号对应的发送波束为网络设备在所述至少两个发送波束中选定的目标发送波束,较佳的,所述目标参考信号对应的信道传输质量大于预设门限值。
本步骤中,终端检测到参考信号,确定与所述参考信号对应的发送波束为网络设备在所述至少两个发送波束中选定的目标发送波束,则对在与该目标发送波束对应的目标接收波束接收到的节能信号执行节能信号的解调解码,否则,不执行节能信号的解调解码。如此,能够降低功耗,提升解调解码节能信号的成功率。
这里,在所述发送波束包括至少两个发送波束,所述至少两个发送波束对应相同的节能信号的情况下,作为一可选的实现方式,步骤201可包括:
在相同的第一时间单元上,通过至少两个接收波束分别接收各自对应的发送波束上发送的节能信号。
需要说明的是,该实现方式对应于网络设备侧为节能信号的传输资源配置至少两个发送波束,并为所述发送波束配置参考信号,其中,不同的发送波束对应不同的参考信号的情形。
下面以网络设备侧的方法中的示例为例,继续阐述对应终端侧的行为,即节能信号为基于PDCCH的节能信号,网络设备为该节能信号控制资源集CORESET配置多个发送beam,并为不同的发送beam配置不同的DRMS,也就是说,不同的发送beam之间所配置的DRMS不同。网络设备(如基站) 在选定的beam上发送节能信号,终端首先接收多个发送beam对应的节能信号,例如高频段模拟波束时,较佳的,终端在相同的第一时间单元上,通过N个接收beam接收各自对应的N个发送beam发送的节能信号,其中,N≥2,且N为正整数。
接着,对每个发送beam对应的基于PDCCH的节能信号的DMRS执行假设检验,该检验较佳的利用简单的序列相关性进行,若终端在相应的beam接收位置检测到该发送beam对应的DMRS,终端执行复杂信道译码操作。
这里,在相同的第一时间单元上,通过至少两个接收波束分别接收各自对应的发送波束上发送的节能信号,具体是指终端在同一个第一时间单元上,利用至少两个波束同时接收各自对应的发送波束上发送的节能信号。
需要指出的是,终端在相同的第一时间单元能够接收多个波束,一般来说需要终端具有这样的能力,比如,终端的天线具有多个面板panel。
作为又一可选的实现方式,步骤101可包括:
在至少两个第一时间单元上,分别接收所述至少两个发送波束发送的节能信号,不同的第一时间单元对应不同的发送波束;
进一步可选地,确定网络设备在所述至少两个发送波束中选定的目标发送波束,可具体包括:
基于预先约定、基站配置或随机选择的方式,对所述至少两个发送波束进行信号检测;
若检测到节能信号,则确定与所述节能信号对应的发送波束为网络设备在所述至少两个发送波束中选定的目标发送波束。
需要说明的是,该实现方式对应于网络设备侧为节能信号的传输资源配置至少两个发送波束,在至少两个第一时间单元上,分别通过所述至少两个发送波束中不同的发送波束发送所述节能信号的情形。
也就是说,网络设备在多个发送beam中选择一发送beam在多个发送时间单元上发送节能信号,相应地,终端在节能信号的不同MO(Monitoring occasion,检测机会)处,根据预先约定、基站配置或者随机选择的方式,分别在多个MO处分别对不同的发送波束进行检测,比如,基站通过RRC信令半静态配置或者基站与终端预先约定的静态配置方式约定不同第一时间单元 (如不同MO)与发送波束的对应关系,这样终端就能分别针对不同波束进行检测。
需要说明的是,MO是从终端角度来说的,从网络设备的角度来说即节能信号的发送机会,由于二者是完全一一对应关系,在此不做区分。
更具体的,基站为节能信号的发送资源,如可以是基于PDCCH的节能信号对应的CORESET配置M个发送beam,比如M=2。基站根据UE所处的信道环境选择一个发送beam,在多个发送机会发送该节能信号,或者基站在不同的第一时间单元(如多个节能信号发送机会)上在多个发送beam上发送节能信号。终端在多个MO上分别按照基站采用不同的发送波束对节能信号进行接收。也就是说,终端在多个MO上对多个beam发送方向进行假设检验。
这里,终端在MO上所检测beam的方向,可以由基站RRC信令半静态配置或者预先约定的方式静态配置,也可以是基站随机选择一个beam进行发送。
比如说index为奇数的MO,终端假定基站的发送波束为发送波束1,然后检测节能信号;index为偶数的MO,终端假定基站的发送波束为发送波束2,然后检测节能信号;在没有发送波束如何检测的先验信息时,终端可以随机交替对发送波束进行检验,比如当前MO可以假定发送波束为1或者2,下一个MO则假定发送波束为2或者1进行检验。
基于图2所示的实施例,作为一较佳的实现方式,步骤201可包括:
在至少两个第二时间单元上,分别接收网络设备在所述至少两个第二时间单元各自对应的传输资源上,通过在所述传输资源对应的至少一个发送波束上发送的节能信号,所述传输资源为所述节能信号对应的资源。
需要说明的是,该实现方式对应于网络设备侧配置至少两个传输资源,所述传输资源为所述节能信号对应的资源;为每个所述传输资源配置至少一个发送波束的情形。
下面以网络设备侧的方法中的示例为例,继续阐述对应终端侧的行为,即当节能信号为基于PDCCH的节能信号时,网络设备(如基站)为基于PDCCH的节能信号配置T个控制资源集CORESET,并为每个CORESET配 置W个发送beam,W≥1,且W为正整数。网络设备可依次在不同的第二时间单元,在不同CORESET上通过各自对应的发送波束发送相同的节能信号。
相应地,终端在对应的发送时间单元(即第二时间单元)接收不同CORESET及其对应的不同波束上的发送的节能信号。
需要说明的是,从终端节点角度,只要终端在一个CORESET对应的一个波束上解调解码出节能信号即可停止后续的波束扫描。
另一种实现方式,终端在不同的CORESET对应的一个波束上检测PDCCH对应的DMRS,如果检测到DMRS才进行解调解码,如果检测不到DMRS则不执行解调解码;如果基站检测到多个DMRS序列,会在选择一个信道传输质量较佳的DMRS序列对应的基于PDCCH的节能信号进行解调解码。
作为一可选的实现方式,在确定网络设备在所述至少两个发送波束中选定的目标发送波束之后,所述方法还可包括:
对与所述目标发送波束对应的目标节能信号进行解调与解码;
本步骤中,对确定网络设备在所述至少两个发送波束中选定的目标发送波束之后,对该目标发送波束对应的目标节能信号进行解调与解码,对其他发送波束不进行解调解码处理,这样不仅能够降低终端功耗,还能够提升解调解码节能信号的成功率。
在所述目标节能信号解调与解码成功后,指示终端执行目标事件,所述目标事件包括:唤醒接收机或者进入睡眠模式。
本步骤中,需要说明的是,目标时间包括但不限于:唤醒接收机或者进入睡眠模式。
本公开实施例的信号传输方法,通过接收网络设备在至少一个发送波束上发送的节能信号,如此,能够实现基于波束的节能信号的传输,保证终端能够根据接收到的节能信号的指示执行相应的事件,达到节省终端电量的目的。
