具体实施方式
由于波束较窄，为使波束准确聚焦于通信的设备上，要进行波束训练以选择最优或次最优的波束。在接入过程中发生的场景是这样的：由于基站发射和接收信道的互易性不存在，终端选择的最优下行波束，未必是基站接收的最优上行波束。此时，终端发送多次随机接入信号，方便基站多次接收随机接入信号的接收质量，以确定接收波束。这样的话，终端多次发送，终端发送的次数多，功耗大，且基站选择波束的过程也相对繁琐。
以下结合说明书附图及示例性实施例对本公开的方案做详细阐述。
如图1所示，本实施例提供一种上行接收波束的确定方法，应用于基站中，包括：
步骤S110：利用N个接收配置，接收终端发送的一个随机接入信号；所述N为不小于2的整数；
步骤S120：分别获取N个所述接收配置对应的接收状况信息；
步骤S130：根据所述接收状况信息，确定上行接收波束的接收配置。
本实施例所述的上行接收波束的确定方法为应用于基站中的方法。终端又可称之为用户设备(User Equipment,UE)。UE在进行随机接入时，会向基站发送随机接入信号。在本实施例中，所述基站会利用UE的随机接入进行后续从该UE接收数据的上行接收波束的接收配置的确定。这里的接收配置可包括上行接收波束的方向角、波束频率以及极化方向等波束的配置参数的至少其中之一。
在本实施例中为了选择出接收UE发送的数据的最优波束或较优波束，基站会利用N个接收配置，这里N个接收配置中的任意两个至少部分不同，从而基站会获得UE发送的一个随机接入信号的多个接收状况信息。这里的接收状况信息可包括接收信号强度或接收信号质量等标识接收情况好坏的参数。
在步骤S130中，将根据接收状况信息，选择出用于接收后续该UE发送的上行数据的接收配置。例如，该确定出的接收配置，可用于接收该UE发送的上行业务数据。在步骤S130中可包括：选择接收信号强度最强对应的接收配置，作为所述上行接收波束的接收配置，在可包括：选择接收信号强度大于预设轻度的对应的接收配置，作为后续上行接收波束的接收配置。例如，接收配置A接收配置B，接收了UE发送的一个随机接入信号，分别得到信号接收强度A和接收信号强度B；若接收强度A大于接收信号强度B，则在步骤S130中可选择接收配置A作为基站后续接收UE的上行业务数据 等上行数据的接收配置。
基站如此操作，UE仅需发送一个随机接入信号，就可以协助基站完成上行接收波束的接收配置的确定，减少了UE发送随机接入信号的次数，减少了发送随机接入信号所占用的通信资源，降低了UE的功耗。
所述步骤S110的可实现方式有多种，以下提供至少两种可实现方式：
可实现方式一：
所述步骤S110可包括：
在接收所述终端的一个随机接入信号的发送过程中，利用一个或同时利用多个所述接收配置接收所述随机接入信号，并至少调整1次所述接收配置，直至利用N个所述接收配置，接收所述随机接入信号。
在本实施例中，基站在接收一个随机接入信号的过程中，会动态的至少调整一个所述接收配置，直到有N个接收配置用于接收UE本次发送的一个随机接入信号。例如，当基站用一个接收配置接收所述随机接入信号时，则所述基站动态调整N-1次接收该随机接入信号的接收配置。在本实施例中，不同的接收配置在时间维度上，采用时分复用或轮询的方式，可轮流接收所述随机接入信号。
可实现方式二：所述步骤S110可包括：
同时利用N个所述接收配置，分别同时接收终端发送的一个随机接入信号。
同时利用N个接收配置，同时接收所述随机接入信号，这样的话，所述基站会获得多个接收状况信息，再通过接收状况信息的相互比较或预设阈值的比较，选择出符合选择条件的接收配置，作为步骤S130中决策出的所述上行接收波束的接收配置。

在实施例中，所述第一循环前缀的长度与基础信号格式中的基础循环前缀的长度相等。
在一些实施中，所述第一循环前缀的长度与所述基础循环前缀的长度的相差长度在预设范围内。这里预设范围可为20％、10％。例如，所述第一循环前缀的长度比基础循环前缀的长度长20％等。
在另一些实施例中，所述第一循环前缀的长度大于或等于M倍所述基础循环前缀的长度，所述M为正整数。在本实施例中所述M可等于所述N。
所述第一前导码的长度可与所述基础信号格式的基础前导码的长度相等或略小或略大。例如，所述第一前导码的长度是0.8倍的所述基础前导码的长度。
在本实施例中任意两个所述第一前导码可相同或不相同。
在本实施例中所述基站向UE发送第一拓展信号格式，相当于指示UE利用了所述第一拓展信号格式发送所述随机接入信号。在实现时，所述基站 也可以不向所述UE发送随机接入信号的信号格式，UE可以根据自身存储的信号格式，构建随机接入信号；例如，利用所述基础信号格式发送所述随机接入信号等。当然，所述UE也可以用通信协议定义的信号格式发送所述随机接入信号。
在一些实施例中，所述步骤S110还可包括：
当所述随机接入信号的长度大于第一预设长度时，利用N个所述接收配置，分段接收所述随机接入信号。
若UE发送的一个所述随机接入信号的长度较长，一个随机接入资源的资源长度不够时，所述UE将可能分段传输。此时，所述基站在步骤S110中将分段接收，例如，分两次接收一个所述随机接入信号。
所述方法还包括：向所述终端发送分段指示；
所述步骤S110可包括：
当所述随机接入信号的长度大于第一预设长度时，分段接收基于所述分段指示发送的随机接入信号。
在UE分段传输时，是分为几段，可以由基站预先指示。故在本实施例中所述基站还会向终端发送分段指示，在步骤S110中基站接收的是UE根据分段指示分段发送的随机接入信号。这样，由于分段指示是基站发送的，基站自然也知道要分为几次进行接收。所述分段指示可用于指示进行分段传输，还可用于指示分段的段数，还可以用于指示分段间隔，即两次分段传输之间的时间间隔或频率间隔等，方便所述基站根据分段指示，自行预先选择号接收配置进行接收。
当然，在实现时，所述UE也可以自行动态确定是否进行分段传输，基站在接收的过程中，可根据接收的随机接入信号的长度，确定出是否接收完整，若未接收完整，则可以认为要分段接收。
如图2所示，本实施例提供一种随机接入方法，应用于终端中，包括：
步骤S210：确定信号格式；
步骤S220：基于所述信号格式，形成随机接入信号；
步骤S230：向基站发送所述随机接入信号。
在本实施例中所述终端首先确定信号格式，再根据信号格式形成随机接入信号，并向基站发送。在本实施例中，一个所述随机接入信号格式用于所述基站利用N个接收配置进行接收，并基于N个所述接收配置的接收状况信息，选择上行接收波束的接收配置。这样的话，所述UE仅需向基站发送一个所述随机接入信号，就协助基站完成了上行接收波束的接收配置的选择，UE发送的随机接入信号的个数少，减少了UE的功耗，减少了通信资源的占用。
在一些实施例中，所述步骤S210可包括：从所述基站接收第一拓展信号格式；其中，所述第一拓展信号格式包括一个第一循环前缀及N个第一前导码；所述N为不小于2的整数。例如，所述第一循环前缀的长度与基础信号格式中的基础循环前缀的长度相等；或，所述第一循环前缀的长度与所述基础循环前缀的长度的相差长度在预设范围内；或，所述第一循环前缀的长度，大于M或等于M倍所述基础循环前缀的长度，所述M为正整数。所述第一前导码的长度可以与所述基础前导码的长度相等或相当。
在一些实施例中，所述方法还包括：当所述随机接入信号的长度大于第一预设长度时，分段传输所述随机接入信号。
在本实施例中，若所述随机接入信号是基于所述第一拓展信号格式形成的，则有可能出现所述随机接入信号的长度过大，例如，大于第一预设长度，这里的第一预设长度可为一个随机接入资源的资源长度。这样的话，就可能出现，一个随机接入资源无法完整的传输一个所述随机接入信号，在本实施例中，则会进行分段传输。例如，利用多个随机接入资源传输一个所述随机 接入信号。
所述当所述随机接入信号的长度大于第一预设长度时，分段传输所述随机接入信号，包括：确定分段段数；根据所述分段段数，分段传输所述随机接入信号。
在本实施例中首先确定分段段数，例如，是分为2段、3段还是更多段。所述分段的方式有多种，以下提供几种示例性的方式：
第一种：所述确定分段段数，包括：接收所述基站发送的分段指示；根据所述分段指示，确定分段段数。在本实施例中直接根据基站的分段指示，进行分段。
第二种：所述确定分段段数，还包括：根据所述随机接入信号的信号长度，和单个随机接入资源的资源长度，确定所述分段段数。在本实施例中由UE自行根据随机接入信号的信号长度和单个随机接入资源的资源长度，来分段。选择用于传输一个所述随机接入信号的多个随机接入资源的资源长度之和，不小于一个所述随机接入信号的信号长度，以确保一个所述随机接入信号的完整传输。
如图3所示，本实施例提供一种随机接入方法，应用于终端中，包括：
步骤S310：确定信号格式；
步骤S320：根据所述信号格式形成一个随机接入信号；
步骤S330：利用S个发送配置发送至少部分所述随机接入信号；其中，所述S为大于等于1的整数。
在本实施例中，所述终端在发送一个随机接入信号时，会利用S个发送配置进行发送。每一个所述发送配置用于发送一个所述随机接入信号中的全部或部分。这样的话，基站的多个接收配置对应的不同天线，均会接收到所述随机接入信号，这样的话，基站将获得多个接收状况信息，例如，多个接 收强度和/或多个接收质量，从而根据所述接收状况信息，方便所述基站通过一个随机接入信号的接收，选择出用于接收UE发送上行数据的接收配置。这里的接收配置可以参见前述实施例中的接收频率、接收方向及极化方向的至少其中之一。这里的发送配置也可以为发送频率、发送方向互极化方向等发送天线的天线参数。
在一些实施例中，所述步骤S310可包括：
预先从基站接收所述随机接入信号的第二拓展信号格式，其中，所述第二拓展信号格式包括：P1个第二循环前缀、P2个第二前导码；
所述P2等于或大于所述P1；一个所述发送配置下至少发送一个所述第二循环前缀和一个所述第二前导码。
在本实施例中所述UE会从基站接收第二拓展信号格式，这里的第二拓展信号格式可为相对于前述的基础信号格式而言的。在本实施例中包括P1个第二循环前缀和P2个第二前导码。P2大于或等于P1。当所述P2等于P1时，所述第二循环前缀和所述第二前导码，在所述第二拓展信号格式中间隔分布。当所述P2大于所述P1，任意两个所述第二循环前缀不相邻分布，即任意两个所述第二循环前缀之间至少间隔一个或更多的所述第二前导码。
在本实施例中UE发送的随机接入信号是基于第二拓展信号格式形成的，在实现时，也可以是基于所述基础信号格式，或所述第一拓展信号格式等其他信号格式形成的。
在一些实施例中，若采用第二拓展格式，则可能出现一个随机接入资源无法完整传输一个所述随机接入信号的现象，故在本实施例中所述步骤330还可包括：当所述随机接入信号的长度大于第一预设长度时，分段传输所述随机接入信号。
所述当所述随机接入信号的长度大于第一预设长度时，分段传输所述随机接入信号，包括：
确定分段段数；
根据所述分段段数，分段传输所述随机接入信号。
同样的在本实施例中，如何进行分段传输，也可包括多种方式：
方式一：
所述确定分段段数，包括：
接收基站发送的分段指示；
根据所述分段指示，确定分段段数。这里分段指示的相关描述可以参见前述实施例的对应部分，此处就不重复了。
方式二：
所述确定分段段数，还包括：
根据所述随机接入信号的长度，和单个随机接入资源对应的数据长度，确定所述分段段数。
如图4所示，本实施例提供一种上行接收波束的确定方法，应用于基站中，包括：
步骤S410：分别接收终端利用多个发送配置发送的一个随机接入信号；其中，一个所述发送配置发送至少部分所述随机接入信号；
步骤S420：根据不同所述配置发送的随机接入信号的接收状况信息，确定上行接波束的接收配置。
这样的话，基站接收UE发送的一个随机接入信号，会得到多个接收信号强度或质量，选择信号强度最大或接收质量最好的接收天线的接收配置，作为所述上行接收波束的接收配置。这样的话，通过一个随机接入信号的接收，就完成了上行接收波束的接收配置的确定。
在一些实施例中，所述方法还包括：
发送随机接入信号的第二拓展信号格式，其中，所述第二拓展信号格式包括P1个第二循环前缀、P2个第二前导码；其中，所述P2等于或大于所 述P1；一个所述发送配置至少用于发送至少一个所述第二循环前缀和一个所述第二前导码。且任意两个所述第二循环前缀在所述第二拓展格式中不相邻设置。这里的第二拓展信号格式的定义可以参见前述对应的实施例。在实现时，所述第二拓展信号格式还包括一个保护间隔。所述保护间隔位于所有第二循环前缀和第二前导码之后。
如图5所示，本实施例提供一种上行接收波束的确定方法，包括：
步骤S510：利用多个发送配置发送多次指定下行信号；
步骤S520：接收终端发送的随机接入信号；
步骤S530：根据所述随机接入信号的接收参数，确定终端发送所述接入信号对应的所述指定下行信号的接收配置；
步骤S540：根据所述终端发送所述接入信号对应的所述指定下行信号的接收配置，确定上行接收波束的接收配置。
这里的指定下行信号可包括同步信号或部分广播信道的时间或频率位置的信号。所述同步信号可包括主同步信号和辅同步信号等。
在本实施例中基站首先发送多次指定下行信号，接收终端基于所述指定下行信号的接收状况信息，发送的随机接入信号；根据所述随机接入信号的接收时间，确定下行信号的接收配置。终端若接收到一个随机接入信号的信号质量好，则会选择与该次指定下行信号的发送视频资源对应的随机接入资源，发送所述随机接入信号。
步骤S530中的接收参数，可包括所述随机接入信号的接收时间或随机接入信号的随机接入资源对应频段，或发送所述随机接入信号的随机接入资源的编号等信息。每一个所述指定下行信号的发送资源与至少一个随机接入资源建立有关联关系，这种关联关系可为时间关联关系或频率关联关系。例如，所述时间关联关系可表现在两个资源对应的时间在预设范围内，所述频域关联关系，可表现在两个资源使用的频段相差预定值或相差在预定范围 内。故步骤S530中可基于所述接收参数及所述关联关系，确定出终端是基于哪个指定下行信号发送的随机接入信号。这种关联关系，所述基站可以预先通知终端。
故在本实施例中的步骤S540可以根据指定下行信号的接收配置，作为上行接收波束的结束配置，从而完成所述上行接收波束的接收配置的确定，以便后续接收该UE的上行业务数据或上行请求信息等。
在一些实施例中，所述步骤S540可包括：根据所述接收配置，确定所述上行接收波束的波束频率、接收角度和极化方向中的至少之一。
在有些实施例中，所述方法还包括：向所述终端发送随机接入资源的资源起始位置。
通过向所述终端发送随机接入资源的资源起始位置，相当于指示了终端在哪些位置上选择基于所述指定下行信号选择的资源的开始位置。这样基站就不用逐一向终端指示每一个随机接入资源的位置。
如图6所述，本实施例提供一种上行接收波束的确定方法，包括：
步骤S610：接收基站利用不同发送配置发送的指定下行信号；
步骤S620：根据各所述指定下行信号的接收状况信息，选择随机接入资源；
步骤S630：利用所述随机接入资源发送随机接入信号。
在本实施例中，所述终端会接收到基站利用不同发送配置发送的指定下行信号，这里的发送配置可为发送方向及计划方向等。这里的指定下行信号可为前述的同步信号等。在步骤S620会根据各个指定下行信号的接收状况信息，确定随机接入资源，利用选择的随机接入资源发送随机接入信号。这样基站就可以根据资源的相关性，确定终端对哪一个指定下行信号的接收强度或接收质量较好，再根据指定下行信号的发送配置和上行接收波束的接收配置之间的关联性，从而确定出上行接收波束的接收配置。这样可以避免终 端发送多次随机接入信号。而所述指定下行信号也为同步信号等有其他功能的信号，从而减少了通信资源的占用和终端的功耗。
在实现时，所述随机接入信号的接收时间用于所述基站选择上行接收波束的接收配置。如何确定上行接收波束的接收配置，可参见前述实施例的对应部分。
在一些实施例中，所述步骤S620可包括：当一个发送配置下发送的所述指定下行信号的接收强度满足预设条件时，选择与所述指定下行信号的接收时间最近的随机接入资源发送所述随机接入信号。
或者，当一个发送配置下发送的所述指定下行信号的接收强度满足预设条件时，根据接收强度满足预设条件的下行信号的次序或编号，选择与所述次序或编号对应的随机接入资源。
例如，分别对随机接入资源和发送所述指定下行信号的发送资源进行了排序或编号。例如，终端对第3个发送资源发送的指定下行信号的接收质量最好或接收强度最大，或大于预设阈值，则终端选择第3个随机接入资源发送所述随机接入信号。在本实施例中，这里的“对应”可为次序相同或编号相同或相对应。
在一些实施例中，所述步骤S620可包括：选择随机接入资源发送所述随机接入信号；其中，所述随机接入资源对应的时间与终端接收所述指定下行信号的接收时间的时间差，为预设时间间隔。这样的话，基站在接收到随机接入信号的接收时间，和指定下行信号的发送时间结合关联关系，则可以确定出终端当前发送的随机接入信号，是基于哪一个指定下行信号发送的，以简化基站的操作。

在示例中，前述拓展信号的循环前缀的长度可以与基本信号格式的循环前缀长度相当，或者是基础信号格式的循环前缀长度2倍相当或更长。
在示例中，基站可以通过信令通知随机接入信号的随机接入资源的与下行信号的发送资源具有关联关系，这种关联关系体现在时间维度上的时间关联性或频域的关联性；例如，两个资源的时间相差在预设时间内，频率相差在预设频率范围内。
在示例中，基站接收的多个连续的随机接入信号组合后的资源起点 与多个下行信号的发送资源可以存在关联关系；多个连续的随机接入信号的资源由多个连续的随机接入信号组合后的资源起点，多个下行信号的发送资源之间的相对顺序和随机接入信号的格式共同确定。这里的下行信号可为前述的指定下行信号。

分段数量由基站通知终端；或者基站通知终端某段随机接入信号延迟到下一个可用随机资源上传输；或者基站通知终端某段随机接入信号资源被打孔；或者终端知晓某段资源被其他业务占用导致随机接入信号分段。
示例二
本示例还提供一种随机接入方法，包括：
终端接收基站指示的随机接入的信号格式，并遵循相应格式传输随机接入信号；这里的信号格式可为前述拓展信号格式，例如，第一拓展信号格式或第二拓展信号格式。
所述随机接入信号由多个前导码重复并连续组合形成，前导码重复可以是没有携带循环前缀前导码的重复，或者是携带循环前缀的前导码的重复；
所述随机接入信号格式中至少还可包括以下参数之一：循环前缀的长度、前导码重复次数、前导码重复后组合的长度。
所述的前导码重复可以是相同的前导码序列重复，或者是不同的前导码序列重复。
拓展信号格式的循环前缀的长度与前导码基础信号格式的循环前缀长度相当，或者是前导码基础信号格式的循环前缀长度的2倍相当或更 长。
随机接入信号上行资源的与下行信号的发送资源有关联关系，关联关系是通过预定义确定或信令通知的相对时间或相对频率偏差。
多个连续的随机接入信号组合后的资源起点与多个下行信道或信号存在关联关系；多个连续的随机接入信号的资源可以通过多个连续的随机接入信号组合后的资源起点，多个下行信道或信号之间的相对顺序和随机接入信号的格式共同确定。
随机接入信号传输所使用的资源可以是连续的也可以非连续的。
在非连续资源上，随机接入信号分段传输，每段的随机接入信号长度不一定相等，分段后的随机接入信号中前导码需具备循环前缀。
终端接收基站通知分段数量；或者终端接收基站通知某段随机接入信号延迟到下一个可用随机资源上传输的信令；或者终端接收基站通知某段随机接入信号的随机接入资源被打孔的信令；或者终端知晓某段资源被其他业务占用导致随机接入信号分段。
示例三：
如图13为例，提供了5种格式的随机接入信号的信号格式，格式0是基础信号格式，没有任何的前导码重复，循环前缀CP也是用于常规覆盖。图13中的GT表示保护间隔，为Guard Time的缩写。而其余4种格式为拓展信号格式，都对基础格式的前导码进行了多次重复，重复的前导码是相同的。区别在于格式1和格式2的循环前缀的长度和基础格式的循环前缀的长度相当，相当可以理解为相等或者在量级上没有明显差异，比如差异值小于20％。这意味着格式1和2在覆盖距离上和基础格式0是相当的，重复的前导码只用于适配基站接收波束的数量，如重复2次，代表可以给基站提供两次波束接收的机会；重复3次，代表可以给基站提供三次波束接收的机会。格式1a和2a既有前导码的重复， 也有相对于基础格式的明显加长的循环前缀，这代表这种格式既可能用于提供给基站多次波束接收的机会，也可以用于更大距离的覆盖，更大距离的覆盖可以通过更长的前导码序列和循环前缀来提供保证，多个前导码的重复形成的长前导码可以提供能量的累加以满足更远的覆盖距离。随机接入信号的信号格式设计不限于图13中提供的5种，相应的设计准则归纳来说：对基础格式的前导码进行不带循环前缀的多次重复，重复的前导码是相同的；对重复后的长前导码添加不同长度的循环前缀，其中某一种格式的循环前缀和基础格式的循环前缀的长度相当；某一种格式的循环前缀的长度超过基础格式循环前缀的长度1倍或更长且很大可能是整数倍。
针对随机接入信号的信号格式中的前导码重复次数的设定，可以依赖于基站分时接收波束的次数。比如，基站有8个接收波束用于初始接入，这8个波束都是模拟波束，可以分时轮转，所以分时接收波束的次数就是8。若8个波束为混合波束，同一个时刻可以接收4个数字波束，则分时接收波束的次数就是2。这个能力将通过随机接入前导格式的选择隐含通知给终端。
本示例中的拓展信号格式可相当于前述示例中的第一拓展信号格式。
示例四：
本示例提供另外一种随机接入方法，大体操作与示例三中类似，但最大的区别在于前导码重复是携带循环前缀一起的重复。这种重复方式可以适用于终端切换了发射波束或者不同的前导码针对不同的终端的设计需求。
如图14所示的例子：信号格式0是基础信号格式，格式1为拓展信号格式的两个前导码分别用于同一个终端的不同的发射波束，所以实际上决定覆盖距离的仍然是前导码的长度，也就是说覆盖距离和基础格式相当，同样循环前缀的长度也和基础格式相当。格式1a也为拓展信号格式，在格式1a中前导码包括前导码1和前导码2，而格式1中的前导码均为前导码1，故格式1a除了在前后两个前导码上使用了不同的前导码序列外，其余都和格式1相同，使用不同的前导码可以适用于不同的终端。格式2和格式2a均为拓展信号格式以循环前缀进行分界的外环重复的基本目的和格式1及格式1a相同，而同一个循环前缀内的内环前导码重复，目的类似于示例三，即可适用于更远覆盖场景，也可以用于提供给基站更多的接收波束的机会，格式2和格式2a可以认为是示例一和本示例中不带循环前缀重复和混合体。格式2和2a之间的区别在于格式2a外环重复的长前导码不同，可以用于不同的终端。在格式2中所有前导码均为前导码1；格式2a包括的前导码包括前导码1和前导码2。
每一种信号格式末尾的保护间隔GT是不做定义的，但GT的作用不能忽略，GT是用来保护随机接入后正常正交频分(OFDM)符号免受干扰的。GT的功能可以被循环前缀替代，所以多次重复的前导码之间没有GT。
实施例中前导码的格式设计不限于图14中提供的5种，相应的设计准则归纳来说：对基础格式的前导码进行带循环前缀的多次重复，重复的前导码可以是相同也可以是不同的。还可以对已经进行了不带循环前缀重复的长前导码进行带循环前缀的多次重复。
本示例提供的拓展信号格式，可为前述示例中第二拓展信号格式。
示例五：
在随机接入过程中，随机接入信号所选择的上行资源的确定是一个非常重要的问题。如示例三和示例四中提供了不同的随机接入前导格式，由于相应的格式占用不同的时间长度，所以随机接入前导格式会影响到上行资源的选择和确定。
本示例提供一种确定随机接入信号所选择的上行资源的方法，可以依托于初始接入过程中使用到的相关下行信号，如基于同步信号、广播信道的时间、频率位置，通过一个设定的相对偏差或者信令通知的相对偏差来确定上行随机接入信号的上行资源。通过唯一性确定上行随机接入信号资源的好处在于，基站可以从上行随机接入信号的位置识别出终端选择的优化的基站下行信号，比如最优的下行同步信号等。若基站存在信道互易性，则基站不仅可以从上行随机接入信号的位置识别出基站的优化的下行发射信号，还能确定基站的优化的上行接收信号。
如图15所示：TRP是基站无线传输节点，SS1和SS2是两个不同的同步信号，SS1和SS2有先后顺序。UE1和UE3所确定的随机接入资源和SS1相关，由SS1的位置映射而来，UE1和UE3与SS1的相对时间差为Δt1，与SS1的相对频率差为Δf1和Δf3。UE2和UE4所确定的随机接入资源和SS2相关，由SS2的位置映射而来，UE2和UE4与SS2的相对时间差为Δt2，与SS1的相对频率差为Δf1和Δf3。
如果不同的随机接入前导码占用的资源是连续的，所说的资源连续可以是实际物理资源或者逻辑资源在时域或者频域上是连续的。仍然如图3所示，UE1和UE3、UE2和UE4所使用的资源是时域上连续的，那么可以通过映射下行信道或信号的先后顺序来决定不同随机接入前导码占用资源的相对位置。UE只要知道随机接入资源的起点位置，而在随机接入资源中的相对顺序可以通过他们各自与同步信号SS对应关系，同 步信号SS1、SS2的相对顺序来一一映射，并结合随机接入信号的格式就可以唯一确认各个UE的随机接入信号资源。这种通过相对顺序隐含确定资源的方式可以有效节省基站给终端指示的信令。
归纳来说，随机接入信号所选择的上行资源的与下行信号的下行资源有关联关系，关联关系是通过预定义和信令通知的相对时间或频率偏差。当存在多个连续的随机接入信号的情况下，多个连续的随机接入信号组合后的资源起点与多个下行信道或信号存在关联关系。多个连续的随机接入信号的各自的资源可以通过多个连续的随机接入信号组合后的资源起点，多个下行信道或信号之间的相对顺序和随机接入信号的格式共同确定。
示例六
由于基站和终端在最大发射功率上的差异，所以为达到下行同步和上行随机接入相当的覆盖范围，随机接入的资源开销特别是随机接入占用的时长远远大于下行同步信号的资源开销，比如在长期演进(LTE)系统中，5ms中只有一个主同步信号符号，其对于的随机接入信号所占用的资源不小于14个符号。这样在新一代移动通信系统中，由于子帧和时隙长度相对于LTE更短，当要满足一些更大距离的覆盖时，随机接入信号占用的资源有可能会超出随机接入时隙或子帧的长度。
新一代移动通信系统中更倾向于使用时分复用TDD模式，在一个时隙或子帧内既有下行也有上行，传输时隙可能有7个或者14个符号，由于业务的不对称性，能够用于上行传输符号数量可能是比较少的，连续的上行传输符号也可能不能完全容纳随机接入信号。
由于随机接入信号可能长度比较长，这样就会较长时间中断其他终 端在发送业务数据时的上行资源，要减少其他终端的正常业务数据的中断时间。
以上多个原因都要随机接入信号支持非连续传输。图4给出了一种非连续传输的例子。图15来源于将图14的连续随机接入信号传输分割后在不连续的资源上进行传输。
示例性地，图15就是将图14中连续的资源分段形成。分段在信令上可以进行明确的分段指示，基站根据资源情况，以指示终端进行合理的分段，分段指示可以是资源分段的段数或者每段内的前导码的长度，这也意味着不同段之间可能允许的前导码的长度也是不同的。分段之后，为保护前导码之后的正常符号，可以在前导码后形成保护时间GT。分段之前如果重复的前导码没有循环前缀，也可以添加循环前缀，如图16所示，分段前多段前导码属于同一个终端，且没有循环前缀，分段后可以为前导码添加循环前缀。
另外一种示例性的方法是对连续的随机接入资源进行打孔以生成非连续的随机接入传输。对TDD模式来说，时隙内的下行资源可以视为被打孔掉上行资源。打孔后，原打孔位置的随机接入信号延迟到后面的比如下一个可用随机接入资源进行传输，如图17所示：第二个前导码的位置被打孔，其相应的传输延迟到下一个可用前导码资源，或者这部分打孔资源被忽略不在利用。打孔后对第一个前导码自然形成了GT，第二个前导码可以增加循环前缀。可以通过通知终端延迟随机接入信号传输的信令来实现打孔的目的。打孔的一个非常重要的原因是相应的随机接入资源被优先级更重要的业务抢占。

工业实用性
本公开实施例提供了上行接收波束的确定方法及装置、随机接入方法及装置、基站及终端。第一方面，基站可以利用多个接收配置接收一个随机接入信号，从而获得多个接收状况信息，再根据接收状况信息，选择下行接收波束的接收配置，这样终端就不发送多个随机接入信号，减少了终端发送随机接入信号的功耗，降低了多次随机接入信号占用的通信资源。第二方面，终端同时利用多个发送参数发送一个随机接入信号，基站自然会接收到每一个发送参数发送的随机接入信号，这样也可以根据一次随机接入信号的接收状况信息，确定出下行接收波束的接收配置。第三方面，终端首先接收指定下行信号，根据指定下行信号的接收状况信息，选择对应的随机接入资源发送给基站，基站就可以根据随机接入信号的接收时间，及随机接入信号的随机接入资源与指定下行信号的发送资源的对应关系，确定出上行接收波束的接收配置，这样终端同样仅需发送一个随机接入信号。总之，终端发送的随机接入信号的个数减少，减少了随机接入信号的信令开销、降低了终端的功耗、减少了通信资源的占用。因此本公开具有工业实用性。
