Description

波束选择方法及装置 技术领域
本公开涉及通信技术领域，尤其涉及一种波束选择方法及装置。
背景技术
随着无线通信技术的飞速发展，授权频谱上的频谱资源大多都被各种通信系统占用，因此为了扩大频率资源，提高波束选择速率和吞吐量，无线通信系统将工作频段扩展到了非授权频谱。对于信号传输特性比较好的频段，如低频段上，无线通信系统的部署已经比较拥挤，因此在第五代移动通信技术(5th Generation，简称为5G)系统的研究中，考虑在较高的频段上部署无线通信系统，并通过波束(beam)的方式在传输数据。
相关技术中，提出了通过授权辅助接入(LicenseAssisted Access，简称为LAA)的机制来使用非授权频段，也就是说，通过授权频段来辅助实现非授权频段的使用。为了保证与其他在非授权频段上工作的通信系统，如无线局域网络(WIreless-FIdelity，简称为WIFI)共存，在LAA中引入了采用先听后说(Listen-Before-Talk，简称为LBT)的信道竞争接入机制，发送端在有数据需要发送时需要检测信道是否空闲，并且只能有在信道处于空闲状态时，发送端才能发送数据。基站在不同的时间上可能采用不同的波束进行数据的传输，用户设备在初始接入过程中会与基站确定最优的传输波束和传输波束，由于在非授权频段上需要进行信道检测，因此可能导致在信道繁忙的情况下，用户设备无法在初始接入过程中确定最优波束，进而影响系统的性能。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
本公开提供的技术方案适用于用户设备接入采用波束进行传输的系统的过程。
图1A是根据一示例性实施例示出的一种波束选择方法的流程图，图1B是根据一示例性实施例示出的一种波束选择方法的场景图，图1C是根据一示例性实施例示出的一种待传输数据通过不同的波束发送的示意图一，图1D是根据一示例性实施例示出的一种待传输数据通过不同的波束发送的示意图二；该波束选择方法可以应用在数据接收端，如用户设备和基站上，如图1A所示，该波束选择方法包括以下步骤 101-103：
在步骤101中，确定设定传输周期内用于监听待传输数据的接收位置。
在一实施例中，设定传输周期内用于监听待传输数据的接收位置可以由基站配置，如果用户设备为数据接收端，基站可通过RRC信令，MAC CE或是物理层信令将接收位置发送给用户设备；在一实施例中，设定传输周期内用于监听待传输数据的接收位置还可以由系统预先在协议中约定。
在一实施例中，设定传输周期内用于监听待传输数据的接收位置可以为设定传输周期内的时间点，如图1C中标记11-标记14所标记的时间点；在一实施例中，设定传输周期内用于监听待传输数据的接收位置可以为设定传输周期内的一个时间窗口，如图1D中标记15所标记的时间窗口，数据接收端可以在该时间窗口中持续监听待传输数据。
在一实施例中，在用户设备为数据接收端时，待传输数据可以为同步块信号，或者为同步块信号和其他能够指示传输波束的波束信息的信令或者信号，具体的数据发送和接收过程可分别参见图2和图3A所示实施例；在基站为数据接收端时，待传输数据可以为用户设备进行接入的随机接入前导码，具体的数据发送和接收过程可参见图4所示实施例。
在步骤102中，在接收位置监听数据发送端通过不同波束发送的待传输数据，待传输数据能够指示对应的传输波束。
在一实施例中，系统可以通过隐式规则预先建立待传输数据与对应的传输波束的对应关系，在通过一个传输波束发送数据时，即选择与该传输波束之间具有对应关系的待传输数据(如同步块信号、随机接入前导码)进行发送。
在一实施例中，待传输数据中可以显性地携带用于标识传输波束的波束信息，由此实现待传输数据能够指示对应的传输波束。
在步骤103中，基于监听结果，确定最优传输波束。
在一实施例中，数据接收端在设定传输周期内的所有接收位置完成监听操作之后，即可基于在每一个接收位置监听到的待传输数据，确定最优传输波束，可将接收质量最高的待传输数据所对应的数据传输波束确定为最优传输波束。例如，设定传输周期内共有4个接收位置，监听到了2个待传输数据，待传输数据1通过波束1，待传输数据2通过波束2传输，待传输数据1的信号接收质量高于待传输数据2的信号接收质量，则可确定波束1优于波束2，可将波束1确定为最优传输波束。
在一示例性场景中，如图1B所示，以移动网络为新一代网络(如5G网络) 并且基站为gNB为例进行示例性说明，但是本公开技术方案并不限定在新一代网络中使用，在图1B所示的场景中，包括gNB10、UE20，其中，UE20在进行初始接入过程中，可在设定传输周期(同步块信号传输周期)监听gNB10发送的同步块信号，或者其他的能够识别波束的信令或者信号，并基于在设定传输周期内的监听结果确定出最优传输波束；或者，gNB10也可在设定传输周期内监听UE20发送的随机接入前导码，并基于在设定传输周期内的监听结果确定出最优传输波束。
本实施例中，通过上述步骤101-103，数据接收端可在设定传输周期内的两个以上的接收位置监听待传输数据，例如，在一个同步块发送周期内的两个以上的接收位置监听同步块信号或者其他能够指示传输波束的信令或者信号，并根据监听结果确定最优传输波束。由此，本公开技术方案实现了数据接收端在用户设备初始接入过程中通过两个以上的接收位置监听待传输数据，进而确定最优的用于通信的波束，避免了相关技术中在信道繁忙时用户设备无法在初始接入过程中确定最优波束的问题。
下面以具体实施例来说明本公开实施例提供的技术方案。
图2是根据一示例性实施例示出的另一种波束选择方法中各个实体的交互流程图；本实施例利用本公开实施例提供的上述方法，以基站为数据发送端、用户设备为数据接收端、待传输数据为同步块信号为例进行示例性说明，基站可在进行信道检测失败导致无法传输同步块信号时执行本实施例的技术方案。如图2所示，包括如下步骤：
在步骤201中，基站基于设定传输周期内待检测信道的信道状态以及设定的位置参数，确定针对每一个波束的目标发送位置。
在一实施例中，设定的位置参数可以为多个发送位置的位置集合，参见图1B中标记11-14所标记的，一个同步块信号传输周期内可以设定有四个发送位置，标记11和标记13为针对波束1的发送位置，标记12和标记14为针对波束2的发送位置；在一实施例中，参见图1C中标记15所标记的，一个同步块信号传输周期内可以设定有一个用于发送同步块信号的发送窗口，发送窗口中可以由针对每一个波束的多个发送位置。
在一实施例中，设定的位置参数可以由系统协议约定；在一实施例中，设定的位置参数可以由基站设定，并且通过RRC信令，或MAC CE，或物理层信令将设定的位置参数发送给用户设备。
在一实施例中，基站可在基于设定的位置参数确定的多个发送位置上使用不同的波束发送同步块信号，但是由于基站要利用非授权频谱资源发送数据时，需要测量信道的信号能量，进而基于信道的信号能量确定出信道是否为空闲，如果不空闲，则 基站不能在信道上使用对应的波束发送数据，因此用于发送同步块信号的发送位置需要为信道状态为空闲并且为基于设定的位置参数确定到的资源。
在步骤202中，基站在针对每一个波束的目标发送位置通过对应的传输波束发送同步块信号。
在一实施例中，参见图1B中标记11-14所标记的，一个同步块信号传输周期内可以设定有四个发送位置，在标记11和标记13所标记的发送位置通过波束1发送同步块信号，在标记12和标记14所标记的发送位置通过波束2发送同步块信号，如果标记11所标记的发送位置，信道检测为信道检测失败，则可检测标记13所标记的发送位置，进行信道检测，并且在信道检测成功时，在标记13所标记的发送位置通过波束1发送同步块信号。
在一实施例中，针对每一个波束，若在一个同步块信号传输周期内确定出多个信道为未占用状态的发送位置，可将第一个信道为未占用状态的发送位置确定为目标发送位置，也即，针对每一个波束，目标发送位置只有一个位置；在一实施例中，针对每一个波束，若在一个同步块信号传输周期内确定出多个信道为未占用状态的发送位置，可将所有信道为未占用状态的发送位置确定为目标发送位置，也即，针对每一个波束，目标发送位置可以有多个。
在一实施例中，参见图1C中标记15所标记的，一个同步块信号传输周期内可以设定有一个用于发送同步块信号的发送窗口，在该发送窗口中，基站可持续检测信道的信道状态，并且在信道检测成功时，使用每一个的波束在信道检测成功的第一个位置或者所有位置发送同步块信号。
在步骤203中，用户设备确定设定传输周期内用于监听同步块信号的接收位置，并在接收位置监听数据发送端通过不同波束发送的同步块信号，同步块信号能够指示对应的传输波束。
在一实施例中，用户设备也可通过设定的位置参数确定设定传输周期内用于监听同步块信号的接收位置。
在一实施例中，系统可以通过隐式规则预先建立同步块信号与对应的传输波束的对应关系，在通过一个传输波束发送数据时，即选择与该传输波束之间具有对应关系的同步块信号(如同步块信号、随机接入前导码)进行发送。
在一实施例中，同步块信号中可以显性地携带用于标识传输波束的波束信息，由此实现同步块信号能够指示对应的传输波束。
在步骤204中，基于监听结果，确定最优传输波束。
在一实施例中，步骤204的描述可参见图1A所示实施例的步骤103的描述，这里不再详述。
本实施例中，公开了一种用户设备初始接入过程中确定最优传输波束的实现方式，基站可在一个设定传输周期内的多个发送位置使用不同的波束发送同步块信号，进而使得用户设备在初始接入过程中确定最优的用于通信的波束，避免了相关技术中在信道繁忙时用户设备无法在初始接入过程中确定最优波束的问题。
图3A是根据一示例性实施例示出的另一种波束选择方法中各个实体的交互流程图，图3B是根据一示例性实施例示出的一种待传输数据通过不同的波束发送的示意图三；本实施例利用本公开实施例提供的上述方法，以基站为数据发送端、用户设备为数据接收端、待传输数据为同步块信号和其他能够识别波束的信令或者信号为例进行示例性说明，基站可在进行信道检测失败导致无法传输同步块信号时执行本实施例的技术方案。如图3A所示，包括如下步骤：
在步骤301中，基站基于设定传输周期内待检测信道的信道状态以及设定的位置参数，确定针对每一个波束的目标发送位置。
在一实施例中，基站可在基于设定的位置参数确定的多个发送位置上使用不同的波束发送同步块信号或是波束指示信令或者波束指示信号，但是由于基站要利用非授权频谱资源发送数据时，需要测量信道的信号能量，进而基于信道的信号能量确定出信道是否为空闲，如果不空闲，则基站不能在信道上使用对应的波束发送数据，因此用于发送同步块信号波束指示信令或者波束指示信号的发送位置需要为信道状态为空闲并且为基于设定的位置参数确定到的资源。
在一实施例中，参见图3B中标记31-34所标记的，一个同步块信号传输周期内可以为每一个波束设定的目标发送位置可以包括一个以上的发送位置，其中对于同步块信号的发送，可以为每一个波束预先配置一个发送同步块信号的发送位置，而其它的发送位置用于发送波束指示信令或者波束指示信号；例如，在标记31所标记的发送位置通过波束1发送同步块信号，在标记32所标记的发送位置通过波束2发送同步块信号，而在随后的发送位置可以使用波束指示信令或者波束指示信号，如果标记33所标记的发送位置通过波束1发送波束指示信令或者波束指示信号，在标记34所标记的发送位置通过波束2发送波束指示信令或者波束指示信号。
在一实施例中，如果在一个设定传输周期内通过波束1成功发送了同步块信号，则在随后的发送位置，可以使用波束1发送波束指示信令或者波束指示信号，也可以不使用波束1再次发送波束指示信令或者波束指示信号。
在一实施例中，参见图1C中标记15所标记的，一个同步块信号传输周期内可以设定有一个用于发送同步块信号的发送窗口，发送窗口中可以有多个可用于发送待传输数据的位置，针对每一个波束，若在发送窗口内确定出多个信道为未占用状态的位置，可将第一个信道为未占用状态的位置确定为目标发送位置，也即，针对每一个波束，目标发送位置只有一个位置；在一实施例中，针对每一个波束，若在一个发送窗口内确定出多个信道为未占用状态的位置，可将所有信道为未占用状态的位置确定为目标发送位置，也即，针对每一个波束，目标发送位置可以有多个。
在一实施例中，设定的位置参数可以由系统协议约定；在一实施例中，设定的位置参数可以由基站设定，并且通过RRC信令，或MAC CE，或物理层信令将设定的位置参数发送给用户设备。
在步骤302中，在目标发送位置中第一个用于发送同步块信号的位置通过对应的传输波束发送同步块信号，执行步骤303或者步骤304。
在步骤303中，若没有成功发送同步块信号，则在后面的其他目标发送位置通过对应的传输波束发送波束指示信令或者波束指示信号，执行步骤305。
在一实施例中，波束指示信令或者波束指示信号可以标识传输波束的波束信息。其中，波束指示信号可以为一个预先定义的导频序列，波束指示信令可以为一个用于指示传输波束的专署信令，也可以为一个已有信令，通过在已有信令中携带标识传输波束的波束信息来确保数据接收端能够识别波束指示信令的传输波束。
在一实施例中，本领域技术人员可以理解的是，波束指示信令可以为一个承载在某个信道上的、具有一定的传输格式的信令，信令的内容中需要携带标识传输波束的波束信息，信令其他部分的内容并不做限定。
在步骤304中，若成功发送同步块信号，则在后面的其他目标发送位置继续发送波束指示信令或者波束指示信号，或者在后面的其他目标发送位置拒绝发送波束指示信令或者波束指示信号。
在步骤305中，用户设备确定设定传输周期内用于监听同步块信号的接收位置，并在接收位置监听数据发送端传输的待传输数据。
在一实施例中，系统可以通过隐式规则预先建立同步块信号与对应的传输波束的对应关系，在通过一个传输波束发送数据时，即选择与该传输波束之间具有对应关系的待传输数据(如同步块信号、随机接入前导码)进行发送。
在一实施例中，同步块信号中可以显性地携带用于标识传输波束的波束信息，由此实现待传输数据能够指示对应的传输波束。
在步骤306中，用户设备基于监听结果，确定最优传输波束。
在一实施例中，步骤306的描述可参见图1A所示实施例的步骤103的描述，这里不再详述。
本实施例中，公开了一种用户设备初始接入过程中确定最优传输波束的实现方式，基站在一个设定传输周期内由于信道检测失败造成无法使用一个波束传输同步块信号时，在设定传输周期内的其他发送位置发送波束指示信令或者波束指示信号，进而实现用户设备尽快地获取最优传输波束，避免了相关技术中在信道繁忙时用户设备无法在初始接入过程中确定最优波束的问题。
图4是根据一示例性实施例示出的另一种波束选择方法中各个实体的交互流程图；本实施例利用本公开实施例提供的上述方法，以用户设备为数据发送端、基站为数据接收端、待传输数据为随机接入前导码为例进行示例性说明。如图4所示，包括如下步骤：
在步骤401中，用户设备基于设定传输周期内待检测信道的信道状态以及设定的位置参数，确定针对每一个波束的目标发送位置。
在一实施例中，用户设备可基站通过RRC信令，或MAC CE，或物理层信令发送的位置参数；基于位置参数确定接收位置，或者基于位置参数确定一个包含多个接收位置的接收窗口。
在一实施例中，用户设备可基于系统约定，确定在设定传输周期内监听待传输数据的位置参数，基于位置参数确定接收位置，或者基于位置参数确定一个包含多个接收位置的接收窗口。
在步骤402中，用户设备在针对每一个波束的目标发送位置通过对应的传输波束发送待传输数据，用于数据接收端基于监听待传输数据的监听结果确定最优波束。
在步骤403中，基站确定设定传输周期内用于监听待传输数据的接收位置，在接收位置监听数据发送端通过不同波束发送的待传输数据，待传输数据能够指示对应的传输波束。
在步骤404中，基站基于监听结果，确定最优传输波束。
在一实施例中，步骤403和步骤404的操作步骤可参见图2所实施例的步骤203和步骤204的描述，这里不再详述。
在一实施例中，基站在确定最优传输波束之后，可向用户设备发送用于指示最优传输波束的消息，例如，基站基于监听随机接入前导码的监听结果确定出波束3为信号质量最好的波束，则可指示用户设备，波束3为信号质量最好的波束，由此用户设备在后续向基站发送数据时，可优先使用波束3发送数据。
本实施例中，公开了一种用户设备初始接入过程中确定最优传输波束的实现方式，用户设备可在一个随机接入过程中通过不同的波束在多个发送位置发送随机接入前导码，进而使得基站在初始接入过程中确定最优的用于通信的波束，避免了相关技术中在信道繁忙时用户设备无法在初始接入过程中确定最优波束的问题。
图5是根据一示例性实施例示出的一种波束选择方法的流程图；该波束选择方法可以应用在数据发送端，如用户设备和基站上，如图5所示，该波束选择方法包括以下步骤501-502：
在步骤501中，基于设定传输周期内待检测信道的信道状态以及设定的位置参数，确定针对每一个波束的目标发送位置。
在一实施例中，确定目标发送位置的实现方式可参见图6所示实施例，这里先不详述。
在一实施例中，设定的位置参数可以由基站设定，也可由系统通过协议约定。
在一实施例中，确定目标发送位置的实现方式可参见图2所示实施例的步骤201的描述，或者参见图4所示实施例的步骤401的描述，这里不再详述。
在步骤502中，在针对每一个波束的目标发送位置通过对应的传输波束发送待传输数据，用于数据接收端基于监听待传输数据的监听结果确定最优波束。
在一实施例中，若用户设备为数据发送端，则用户设备可在目标发送位置通过对应的传输波束发送随机接入前导码；在一实施例中，若基站为数据发送端，则基站可在目标发送位置通过对应的传输波束发送同步块信号，或者同步块信号和波束指示信令或波束指示信号。
在一实施例中，若基站为数据发送端，则可通过图2和图3A所示实施例描述的方式实现待传输数据的发送和接收，这里不再详述。
在一实施例中，若用户设备为数据发送端，则可通过图4所示实施例描述的方式实现待传输数据的发送和接收，这里不再详述。
本实施例中，公开了一种用户设备初始接入过程中确定最优传输波束的实现方式，数据发送端可以基于设定的位置参数确定出多个发送位置，并且基于信道状态从多个发送位置中选择目标发送位置，进而实现用户设备尽快地获取最优传输波束。
图6是根据一示例性实施例示出的又一种波束选择方法的流程图；本实施例利用本公开实施例提供的上述方法，以数据发送端如何确定目标发送位置为例进行示例性说明。如图6所示，包括如下步骤：
在步骤601中，基于设定的位置参数，确定针对每一个波束的可用于发送待传 输数据的发送位置或者发送窗口。
在一实施例中，设定的位置参数可以为多个发送位置的位置集合；在一实施例中，设定的位置参数还可以为一个用于发送同步块信号的发送窗口。

在一实施例中，对于非授权频谱资源，数据发送端在可用于发送待传输数据的发送位置或者发送窗口发送数据之前，先进行信道检测，如果信道检测为信道状态为未占用状态，则可将可用于发送待传输数据的发送位置或者发送窗口确定为目标发送位置。在一实施例中，针对每一个波束，可将信道状态为非占用状态的所有发送位置均确定为目标发送位置；在一实施例中，针对每一个波束，也可以只将信道状态为非占用状态的第一个发送位置确定目标发送位置。
本实施例中，通过设定的位置参数确定出可用于发送待传输数据的发送位置或者发送窗口后，可进一步通过信道检测确定出目标发送位置，进而实现数据的发送。
