Description

一种上行传输码本确定方法及设备
本申请要求在2017年8月11日提交中国专利局、申请号为201710686814.9、发明名称为“一种上行传输码本确定方法及设备”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,特别涉及一种上行传输码本确定方法及设备。
背景技术
多输入多输出系统(Multiple-Input Multiple-Output,MIMO)技术是通过在终端和演进型基站(evolved Node B,eNB;下称基站)分别使用多个发射天线和接收天线,MIMO技术能充分利用空间资源,使得传输信号通过终端和基站的多个天线传送和接收,进而能够在不增加频谱资源和天线发射功率的情况下,成倍的提高系统信道容量,从而改善通信质量。
目前,为了进一步的提升MIMO技术所带来的改善通信质量的增益,在第五代移动通信技术(5-Generation,5G)中采用了大规模天线技术。其中,基站的天线中可以包括数量庞大的天线单元和收发单元,例如天线单元和收发单元的数量都可以为128、256或者512,终端中也可以配置由数量较多的天线单元组成的天线阵列,在进行通信时,可以通过基站和终端的多个天线进行信号的发送或者接收,以减少信号衰减,提升通信质量。通常来讲,在5G通信系统中,可以采用支持基于码本的上行传输方案,也可以采用支持非码本的上行传输方案。
其中,对于基于码本的上行传输方案,是指在基站和终端预先配置多个码本,每个码本包含多个预编码矩阵,再通过选择的码本确定其包含的预编码矩阵,采用最终确定的预编码矩阵进行数据传输。目前,基站根据终端上报的探测参考信号(Sounding Reference Signal,SRS)资源确定终端采用的码本信息,并将码本信息通知终端,终端则根据基站的通知确定相应的码本,但目前基站仅是根据SRS资源指示的信道状况来进行码本的配置,并未考虑终端的当前状态,因此可能终端的当前状态不足以支持基站配置的码本。

附图说明
为了更清楚地说明本申请实施例的技术方案,下面将对本申请实施例中所需要使用的附图作简单地介绍,显而易见地,下面所介绍的附图仅仅是本申请的一些实施例,对于本领域普通技术人员来讲,在不付出创造性劳动的前提下,还可以根据这些附图获得其他的附图。
图1为本申请实施例提供的上行传输码本确定方法的流程示意图;
图2为本申请实施例提供的上行传输码本确定方法的流程示意图;
图3为本申请实施例提供的终端的一种结构示意图;
图4为本申请实施例提供的基站的一种结构示意图;
图5为本申请实施例提供的计算机装置的一种结构示意图。
具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚,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。
下面介绍本申请实施例的技术背景。
目前,对于基于码本的上行传输方案,基站是根据终端上报的探测参考信号(Sounding Reference Signal,SRS)资源确定终端采用的码本信息,并将码本信息通知终端,终端则根据基站的通知确定相应的码本,但目前基站仅是根据SRS资源指示的信道状况来进行码本的配置,并未考虑终端的当前状态,因此可能终端的当前状态不足以支持基站配置的码本,则会造成通信过程无法正常进行的情况,使得用户体验质量不佳。
鉴于此,本申请实施例提供一种上行传输码本确定方法,在该方法中,终端可以向基站上报终端当前的数据传输能力信息,以使基站在进行码本的确定时,可以依据终端的当前的数据传输能力信息来确定适合终端当前状况的码本,或者通知终端让其根据自己的当前状况自行确定码本,这样,不管是基站选择的码本,还是终端自行确定的码本,都是符合终端当前的实际状况的,且符合终端当前的码本支持能力,使得用户通信体验质量能够更佳。
下面结合附图介绍本申请实施例提供的技术方案。
请参见图1,本申请一实施例提供一种上行传输码本确定方法,该方法的流程描述如下。该方法可以通过本申请实施例提供的终端来执行,同时,在下面的描述中,同时还会 涉及到基站侧的上行传输码本确定方法的流程。
步骤101:终端向基站发送数据传输能力信息;数据传输能力信息用于表征终端当前的天线能够支持的数据传输的能力;
步骤102:终端接收基站发送的码本指示信息;码本指示信息用于指示终端进行上行传输的码本;或者码本指示信息用于表征基站对数据传输能力信息译码成功或者未成功的确认信息;
步骤103:终端基于码本指示信息确定上行传输对应的码本。
本申请实施例中,在终端和基站进行通信之前,基站和终端可以预先约定或配置一个或多个码本,例如可以是终端在不同的天线结构时配置不同的码本。其中,终端中的天线是可以根据终端的使用状况来进行选择性关闭或者开启的,例如在终端检测到电量不足时,则可以选择关闭一些天线,这样,就可以减少这些天线工作时需要使用的电量,以起到省电的作用。这样,当某些天线被关闭之后,终端的天线结构则会发生变化。
本申请实施例中,终端可以向基站发送数据传输能力信息,所述数据传输能力信息用于表征所述终端当前的天线能够支持的数据传输的能力。其中,在终端的天线结构不同时,对于数据传输的支持能力也是不同的,因此数据传输能力信息则可以是终端当前的天线结构。具体的,终端可以是在天线结构发生变化之后,向基站发送当前的数据传输能力信息;或者,终端也可以是周期性的向基站发送数据传输能力信息,当然,在具体的应用中,还可以按照其他可能的方式来发送数据传输能力信息,本申请对此不做限制。
其中,终端发送的数据传输能力信息可以包括但不限于以下信息中的一个或者多个:
(1)终端能够使用的面板(panel)的数量。其中,panel是指终端中的一组天线,例如可以是处于同一平面的天线的集合,可以是方向指向性相同的天线的集合,也可以是对应同一个射频通路的天线的集合,也可以是一组多个射频通路对应的天线,也可以是一组具有相同或相似特性的收发单元(Transmission Receive Unit,TRU或者TXRU)或者天线单元的集合,例如,同一个panel内的收发单元(或天线单元)具有相同的模拟发送波束,一个panel内的收发单元具有一定的相关性等,或者同一个panel内的收发单元(或天线单元)采用同一个波束组内的发送波束等。
(2)每个panel包括的收发单元的数量。其中,一个收发单元可以与一个天线单元连接,也可以与多个天线单元连接。
(3)每个panel包括的天线端口的数量。

本申请实施例中,终端可以将终端当前的天线信息发送给基站,也可以是终端根据终端当前的天线确定一个或者多个能够采用的码本,并将确定的码本或者与码本对应的一个或者多个信息发送给基站。若是基站接收到的是终端当前的天线信息,则基站可以根据该天线信息确定一个或者多个码本,并将该码本或者码本对应的一个或者多个信息发送给终端;若是基站接收到的是终端确定的码本或者与码本对应的一个或者多个信息,则基站可以向终端反馈一个确认信息,用于指示终端是否采用终端自己确定的码本,或者基站也可以为终端指定一个码本。

在基站确定适合该终端当前状态的码本之后,基站则可以根据确定结果生成码本指示 信息,该码本指示信息用于指示基站为终端确定的用于进行上行传输的码本。具体的,该码本指示信息可以包括但不限于以下信息中的一种或者多种:

(2)用于指示码本序号的码本序号选择信息。其中,为便于码本的管理,可以对多个码本进行编号,且终端和基站中对相同的码本的序号需相同。则码本序号选择信息则是用于是指基站为终端确定的码本的序号,那么终端在接收到码本序号选择信息之后,则可以直接根据码本序号选择信息指定的序号确定进行上行数据传输采用的码本。
(3)基站为所述终端配置的参考信号天线端口的数量。基站也可以不直接通知终端为其确定的码本是哪种类别或者具体的序号,则基站可以通知终端为终端确定的码本对应的天线端口的数量,那么终端在收到基站为所述终端配置的参考信号天线端口的数量之后,则可以根据这个数量与码本的对应关系确定进行上行数据传输采用的码本。具体的, 终端中的天线可以包括不同维度的天线,例如垂直维度的天线和水平维度的天线,那么相对应的,天线端口也可以包括垂直维度的天线端口和水平维度的天线端口,也就是说,这里所指的天线端口的数量可以是总的天线端口的数量,也可以是不同的维度的天线端口的数量,例如垂直维度的天线端口的数量和水平维度的天线端口的数量。
(4)码本对应的天线的数量。基站可以通过发送码本对应额天线的数量的方式通知终端为其确定的码本,那么终端在收到天线的数量之后,则可以根据天线的数量与码本的对应关系确定进行上行数据传输的码本。具体的,天线的数量可以是总的天线的数量,也可以是不同的维度的天线的数量,例如垂直维度的天线的数量和水平维度的天线的数量。
(5)码本对应的采样率。采样率可以是过采样率,以生成更多的预编码矩阵,这样,终端除了可以在终端的天线对应的方向上进行数据的传输,还可以在除这些方向的其他方向进行数据的传输,过采样率即是用于表征其他方向的数量的多少的值。也可以是子采样率,用于从一组较多数目的预编码矩阵中去掉一些预编码。例如基站和终端约定了一些预编码矩阵的生成方式,其对应一定数目预编码矩阵。这样,通过基站为终端配置采样率,可以在此基础上生成更多的预编码矩阵或选择其中的一部分预编码矩阵。基站可以通过发送码本对应的采样率的方式通知终端为其确定的码本,那么终端在收到采样率之后,则可以根据采样率与码本的对应关系确定进行上行数据传输的码本。
(6)码本对应的天线间的相位旋转因子。天线间的相位旋转因子对应于用来确定天线间的相位旋转的信息。可以是一个确定的数值,也可以是一组数的集合,也可以是指示具体的相位旋转的指示信息,也可以是一个指示天线相位旋转相位的集合的指示信息。
(7)用于指示选择所述panel中的一个或者多个panel的panel选择信息。panel选择信息可以是基站选择的panel的信息,也可以是SRS资源指示信息(SRS resource index,SRI)。panel选择信息也可以是一个预编码指示信息,该预编码指示信息用于指示基站为终端选择的panel。panel选择信息还可以采用bitmap的方式发送给终端,例如基站为终端选择了一个或者多个panel,每一个panel可以采用1比特进行编码,当panel的对应位为1时则表示基站为终端选择了该panel,例如当终端包括4个panel时,且基站向终端发送的bitmap为1101时,则表示基站为终端选择panel序号为0、1、3,而序号为2的panel没有被选择。
(8)传输秩指示(Rank Indication,RI)信息。其中,RI信息用于指示基站为终端配置的进行上行传输时的秩。那么终端接收到该RI信息之后,可以根据RI信息确定与该RI信息对应的码本,也可以根据RI信息以及其他信息综合来确定对应的码本。这里的RI信息不仅用于确定码本,还可以用于确定基站为该终端配置的数据流数。
(9)码本中的功率因子指示信息。功率因子指示信息对应于用来确定码本中天线间的功率的信息。功率因子指示信息可以 是一个确定的数值,也可以是一组数的集合,也可以是指示具体的功率或功率差的指示信息,也可以是一个指示功率或功率差的集合的指示信息。终端收到功率因子指示信息之后,则可以知道如何确定码本中天线间的功率,以及根据功率确定码本。
(10)码本对应的预编码矩阵分组信息。预编码矩阵分组信息可以包含预编码组的数量信息,预编码组内的预编码数量信息,每个预编码组内的预编码间的间隔信息,所有预编码组间的间隔信息中的一个或多个。终端接收到预编码矩阵分组信息之后,则确定码本对应的预编码矩阵分组情况,再结合基站发送的预编码指示信息和/或传输秩指示信息,就可以确定码本信息。
(11)码本对应的天线结构。例如天线结构包括两个维度,天线结构为两个维度各自包含的天线数目。例如维度为垂直维和水平维,天线结构为垂直维的天线数目和水平维的天线数目。
其中,基站也可以给终端配置新的码本,即与预先存储在终端和基站中的码本皆不同的码本,那么基站需要将新码本包括的信息通知给终端,新码本包括的信息例如可以是上述采样率、相位旋转因子等信息。当然,码本指示信息还可以包括其他可能的参数信息,本申请实施例对此不做限制。
具体的,终端还可以向基站发送上行参考信号,基站则可以对终端发送的上行参考信号进行测量,并根据测量结果和上述对数据传输信息的译码结果结合确定该终端进行上行传输采用的码本,并生成码本指示信息。对于上行参考信息测量这一部分内容属于现有技术的范畴,因此在此不再赘述。
基站在生成上述码本指示信息之后,则可以将码本指示信息发送给终端。终端接收到码本指示信息之后,则可以根据码本指示信息中包括的信息确定基站为其指定的码本,并采用这种码本来进行上行数据的传输。具体的,终端如何基于码本指示信息包括的信息确定码本的过程可以参见上述码本指示信息包括的信息部分的描述,在此不再赘述。
本申请实施例中,基站发送给终端的码本指示信息或者码本更新指示信息都可以通过半静态信令或者动态信令进行发送。半静态信令例如可以是无线资源控制(Radio Resource Control,RRC)信令或者媒体接入控制信道单元(Media Access Control Channel Element,MAC CE)信令;动态信令例如可以是下行物理控制信道(Downlink Control Information,DCI)信令。
具体的,基站生成的码本指示信息还可以包括多个部分,例如码本指示信息可以包括第一指示信息和第二指示信息。其中,第一指示信息可以是上述码本指示信息包括的信息中的一个或者多个,第二指示信息可以是上述码本指示信息包括的信息中出第一指示信息信息之外的其余信息中一个或者多个。当然,码本指示信息也不限于包括两部分的信息,还可以三部分或者更多分组的信息,具体的可以根据实际应用进行合理的设置,本申请实 施例对此不作限制。
其中,当基站生成的码本指示信息包括多个部分的信息时,基站则可以对多个部分的信息联合或独立发送。例如,基站可以在不同的信道和/或不同的时刻将不同部分的信息发送给终端。
例如,当码本指示信息包括第一指示信息和第二指示信息时,基站可以通过MAC CE信令将第一指示信息发送给终端,以及通过DCI信令将第二指示信息发送给终端。
例如,当第一指示信息包括panel选择信息,例如panel选择信息可以为SRI指示信息,以及第二指示信息包括码本对应的天线端口数量信息时,则基站可以在终端进行初始化接入的波束扫描之后将第一指示信息发送给终端,以及在终端进行上行数据的调度是再将第二指示信息发送给终端。
当然,第一指示信息和第二指示信息也可以通过相同的信道和/或相同的时刻发送给终端,本申请对此不做限制。
下面将以具体的例子对上述通过码本指示信息指示终端相应的码本的方法进行说明。
终端和基站可以协议约定了N种码本,终端向基站发送的数据传输能力信息可以包括垂直维和水平维的TXRU数目,或者天线单元数目,以及码本种类的码本种类选择信息等,其中码本种类信息可以包括第一种和第二种码本,其中第二种码本中的每一个码本对应于不同的传输流数。基站接收到终端的数据传输能力信息后,结合对上行参考信号的测量,确定终端采用第二种码本进行传输,并确定了终端的传输流的数量。基站向终端发送码本指示信息,所述码本指示信息包含第二种码本的指示信息和RI,RI用于指示传输秩(传输流的数量)。终端根据这个码本指示信息,就可以知道采用第二种码本中流数为TRI的码本进行传输。
第二种实施方式为:在基站接收到终端发送的数据传输能力信息之后,对数据传输能力信息进行译码,并向终端反馈码本指示信息,该码本指示信息为用于表征基站对数据传输能力信息译码成功或者未成功的信息。
具体的,当基站对数据传输能力信息译码成功时,基站则可以根据数据传输能力信息知道终端可以支持的码本,则基站可以直接向终端反馈用于表征基站已经对数据传输能力信息译码成功的码本指示信息。相对应的,终端在收到该码本指示信息之后,则可以知道基站已经成功译码数据传输能力信息,且基站并未为其指定需要采用的码本,那么终端则可以直接通过终端发送给基站的数据传输能力信息确定终端进行上行数据传输的码本,并采用该码本进行上行数据的传输。
具体的,当基站对数据传输能力信息译码未成功时,基站则会向终端反馈用于表征基站对数据传输能力信息译码未成功的码本指示信息。相对应的,终端接收到该码本指示消息之后,则可以知道基站未成功译码数据传输能力信息,那么可能是数据传输能力信息传 输过程中发生的差错等,则终端会重新向基站发送终端当前的传输能力信息。或者,若是终端当前已经在采用确定的码本进行上行数据传输了,那么终端也可以继续采用当前正在采用的码本进行上行数据的传输。
本申请实施例中,基站还可以在接收到终端发送的数据传输能力信息之后,向终端发送的码本指示信息可以包括用于指示终端进行上行传输的码本的信息和用于表征基站对数据传输能力信息译码成功或者未成功的信息。其中,基站可以在不同时刻和/或不同信道将这两部分信息发送给终端,基站也可以在相同时刻和/或相同信道将这两部分信息发送给终端。那么,终端在接收到这两部分信息之后,则可以根据这两部分信息来确定进行上行传输采用的码本。
本申请实施例中,终端在接收基站发送的码本指示信息之后,还可以根据码本指示信息和终端向基站发送的数据传输能力信息综合来确定行上行传输采用的码本。其中,若是终端最终确定的码本与基站码本指示信息中指示的码本不同,终端还可以将最终确定的码本信息发送给基站,以使得基站能够知道该终端采用的码本。
本申请实施例中,还可能存在这样的情况,在终端向基站发送数据传输能力信息之后,则终端可以开始计时,并确定在预设时间阈值内是否接收到基站的反馈信息,该反馈信息可以是上述的码本指示信息,也可以是用于更新码本的码本更新指示信息。若是终端确定在预设时间阈值内未接收到基站的反馈信息,则终端可以基于发送给基站的数据传输能力信息进行用于上行数据传输的码本,或者,若是终端当前已经在采用确定的码本进行上行数据传输了,那么终端也可以继续采用当前正在采用的码本进行上行数据的传输。
本申请实施例中,基站还可以向终端发送传输预编码矩阵指示(Transmission Pre-coding Matrix Indicator,TPMI)信息,TPMI信息用于指示终端所采用的码本中的预编码矩阵。因此,在终端接收到该TPMI信息,且终端已经确定进行上行数据传输所采用的码本之后,则可以根据TPMI信息和TRI信息以及确定采用的码本来确定该码本中与TPMI信息和TRI信息对应的预编码矩阵,并采用该预编码矩阵来进行上述数据的传输。
本申请实施例中,在终端已经采用确定码本在进行上行数据传输时,终端的天线还可能会发生变化。例如当终端电量不足时,可能会关闭其中一部分的天线。那么终端可以将当前的数据传输能力信息发送给基站。
相应的,基站在可以接收基站发送的数据传输能力信息之后,还可以根据该数据传输能力信息确定终端当前正在采用的码本是否需要更新,并生成码本更新指示信息。其中,码本更新指示信息用于指示终端对当前正在采用的码本进行更新或者不更新。
在终端接收到基站发送的码本更新指示信息之后,则可以确定是否需要对当前正在采用的码本进行更新。若终端确定需要更新当前正在采用的码本,则终端可以重新确定进行 上行数据传输的码本。具体的,重新确定码本的过程即为上述确定码本的过程,即上述第一种实施方式或者第二种实施方式描述的过程,因此对于此的描述可以参考上述第一种实施方式或者第二种实施方式的描述,在此不再赘述。或者,若终端确定不更新当前正在采用的码本,则终端可以继续采用当前正在采用的码本。
本申请实施例中,基站发送给终端的码本更新指示信息也可以通过半静态信令或者动态信令进行发送。半静态信令例如可以是无线资源控制(Radio Resource Control,RRC)信令或者媒体接入控制信道单元(Media Access Control Channel Element,MAC CE)信令;动态信令例如可以是下行物理控制信道(Downlink Control Information,DCI)信令。
本申请实施例中,基站向终端发送传输预编码矩阵指示信息;所述传输预编码矩阵指示信息用于从所述码本指示信息所对应的码本中指示终端上行传输对应的预编码矩阵。
综上所述,本申请实施例中,终端可以向基站上报终端当前的数据传输能力信息,以使基站在进行码本的确定时,可以依据终端的当前的数据传输能力信息来确定适合终端当前状况的码本,或者通知终端让其根据自己的当前状况自行确定码本,这样,不管是基站选择的码本,还是终端自行确定的码本,都是符合终端当前的实际状况的,且符合终端当前的码本支持能力,即终端当前的状态足以支持所采用的码本,这样用户通信体验质量能够更佳。
