Description

一种探测参考信号SRS周期的配置方法及装置 技术领域
本申请涉及无线通信技术领域，特别涉及一种探测参考信号SRS周期的配置方法及装置。
背景技术
探测参考信号(sounding reference signal，SRS)是终端设备发送给网络设备的上行参考信号，用于估计上行信道性能，为上行资源调度以及下行波束赋形提供参考。
现有技术中，SRS信号可以周期性发送，SRS周期的配置与小区用户数密切相关。小区用户数较少时，配置较短的SRS周期，可以尽可能保障用户下行的波束赋形(beamforming，BF)性能，小区用户数较多时，配置较长的SRS周期，可以保障用户基本的SRS测量性能，避免部分用户因分配不到SRS资源而产生掉话。然而，SRS周期的调整需要通过无线资源控制(radio resource control，RRC)信令对用户的SRS资源进行重配。若根据小区用户数实时地调整SRS周期，在用户数短时间内波动较大或是用户数统计不及时不准确等场景下，会导致SRS周期调整过于频繁，产生巨大的信令开销。
发明内容
本申请实施例提供一种探测参考信号SRS周期的配置方法及装置，用以有效地配置SRS周期，减小信令开销。
第一方面，本申请实施例提供一种探测参考信号SRS周期的配置方法，该方法可由通信装置执行，例如网络设备或网络设备中的芯片，该方法包括：通信装置获取第一小区的至少一个邻区在第一时段内的无线资源控制RRC连接用户数，根据第一小区的至少一个邻区在第一时段内的RRC连接用户数，预测第一小区在第二时段内的RRC连接用户数，根据预测的第一小区在第二时段内的RRC连接用户数，为在第二时段内接入第一小区的终端设备配置SRS周期。
采用上述设计，通信装置可在第二时段到来前，根据第一时段内第一小区的至少一个邻区的RRC连接用户数，来预测第二时段内第一小区的RRC连接用户数，进而为在第二时段内接入第一小区的终端设备配置SRS周期。由此可知，通信装置可预先为第一小区配置第二时段内可用的SRS周期，在第二时段内无需重新配置，从而可避免SRS周期调整过于频繁的问题，有效降低SRS周期配置的信令开销。同时，又可使配置的SRS周期符合第一小区在第二时段内的接入情况。
在第一方面的一种可能的设计中，针对第一小区的至少一个邻区中的每个邻区，该邻区在第一时段内的RRC连接用户数包括该邻区在第一时段内的各个时刻的RRC连接用户数。如此，所述预测的第一小区在第二时段内的RRC连接用户数可以为，第一小区的至少一个邻区在第一时段内的第一时刻的RRC连接用户数之和，其中，该至少一个邻区在第一时刻的RRC连接用户数之和大于或等于该至少一个邻区在第一时段内的其他时刻的RRC连接用户数之和。或者，也可以理解为，所述预测的第一小区在第二时段内的RRC连接用户数为，第一小区的至少一个邻区的RRC连接用户数之和在第一时段内可达到的 最大值。
采用上述设计，由于可根据在第二时段之前的第一时段内，第一小区的至少一个邻区的RRC连接用户数之和的最大值，来预测第二时段内第一小区的用户数，因此可得到在第二时段内可能接入第一小区的最大RRC连接用户数，根据该最大的RRC连接用户数来配置第二时段内的SRS周期，可有效避免当大量终端设备在第二时段内批量接入第一小区时，部分终端设备因分配不到SRS资源而产生掉话的问题。
在第一方面的一种可能的设计中，通信装置可根据预测的第一小区在第二时段内的RRC连接用户数，以及RRC连接用户数与SRS周期之间的映射关系，为在第二时段内接入第一小区的终端设备设置SRS周期。其中，所述RRC连接用户数与SRS周期之间的映射关系可以是预定义的，也可以是预先配置在通信装置中的，此外，该映射关系也可以由通信装置根据需要适时调整。
在第一方面的一种可能的设计中，通信装置可实时统计第一小区的RRC连接用户数，并向第一小区的至少一个邻区发送(例如，可以周期性地发送)统计的第一小区的RRC连接用户数，实时统计的第一小区的RRC连接用户数用于每个邻区配置SRS周期。如此，可支持第一小区的各个邻区也能够采用与第一小区相同或类似的方式来配置SRS周期，从而有效减小配置SRS周期的信令开销。
第二方面，本申请实施例提供另一种探测参考信号SRS周期的配置方法，该方法可由通信装置执行，例如网络设备或网络设备中的芯片，该方法包括：通信装置获取第一小区的RRC连接用户数在一个变化周期内的历史统计数据，所述变化周期包括多个时段，所述历史统计数据包括第一小区在该变化周期内的每个时段的RRC连接用户数；通信装置根据第一小区在一个变化周期中与第三时段处于相同位置的时段的RRC连接用户数，预测第一小区在第三时段的RRC连接用户数；通信装置根据预测的第一小区在第三时段的RRC连接用户数，为在第三时段内接入第一小区的终端设备配置SRS周期。
采用上述设计，通信装置可在第三时段到来前，根据第一小区的RRC连接用户数的历史变化规律来预测第三时段内第一小区的RRC连接用户数，从而为第三时段内接入第一小区的终端设备配置SRS周期。如此，通信装置可预先为第一小区配置第三时段内可用的SRS周期，在第三时段内无需重新配置，从而可避免SRS周期调整过于频繁的问题，有效降低SRS周期配置的信令开销。同时，又可使配置的SRS周期符合第一小区在第三时段内的接入情况。
在第二方面的一种可能的设计中，该通信装置获取第一小区的RRC连接用户数在一个变化周期内的历史统计数据可包括：通信装置获取第一小区在过去的设定时长范围内的RRC连接用户数，根据该第一小区在过去的设定时长范围内的RRC连接用户数，确定变化周期，该设定时长范围包括多个变化周期；针对一个变化周期中的每个时段，通信装置根据第一小区在该设定时长范围内包括的多个变化周期中的该时段的RRC连接用户数，确定历史统计数据中第一小区在该时段的RRC连接用户数。如此，可使得第一小区的RRC连接用户数在一个变化周期内的历史统计数据能够反映第一小区的RRC连接用户数的变化规律，从而为预测第一小区在第三时段内的RRC连接用户数提供指导。
在第二方面的一种可能的设计中，所述历史统计数据中第一小区在该时段的RRC连接用户数可以为该第一小区在设定时长范围内包括的多个变化周期中的该时段的RRC连接用户数的平均值；或者，所述历史统计数据中第一小区在该时段的RRC连接用户数为 该第一小区在设定时长范围内包括的多个变化周期中的该时段的RRC连接用户数经过数据滤波的值；或者，通信装置还可根据第一小区在设定时长范围内包括的多个变化周期中的该时段的RRC连接用户数的累积分布曲线，来确定历史统计数据中第一小区在该时段的RRC连接用户数。
采用上述设计，通信装置可采用多种可能的方式来确定历史统计数据中第一小区在一个RRC连接用户数的变化周期的各个时段对应的RRC连接用户数的具体数值，从而可有效提高SRS周期配置方法的灵活性。

实施例一
请参考图2，为本申请实施例提供的一种探测参考信号SRS周期的配置方法的流程示意图，该方法包括如下步骤：
步骤S201、通信装置获取第一小区的至少一个邻区在第一时段内的RRC连接用户数。
本申请实施例中，通信装置可以为图1中所示的通信系统中的网络设备或网络设备中的芯片，该通信装置的覆盖下可包括一个或多个小区。第一小区是指该通信装置所覆盖的其中一个小区。该第一小区的至少一个邻区可以包括该通信装置覆盖下的小区，也可以包括其他通信装置(如其他网络设备)覆盖下的小区，本申请并不限定。
若上述至少一个邻区中的某一邻区与第一小区均在该通信装置的覆盖下，那么该通信装置可以直接获取该邻区在第一时段内的RRC连接用户数，例如从内存中直接读取。若某一邻区与第一小区在不同通信装置的覆盖下，那么该通信装置可通过通信装置之间的接口从管辖该邻区的另一通信装置处获取该邻区在第一时段内的RRC连接用户数。
所述第一时段可包括多个时刻，针对第一小区的至少一个邻区中的每个邻区，该邻区在第一时段内的RRC连接用户数包括该邻区在第一时段内的各个时刻的RRC连接用户数。
步骤S202、通信装置根据第一小区的至少一个邻区在第一时段内的RRC连接用户数，预测第一小区在第二时段内的RRC连接用户数，该第二时段在第一时段之后。
本申请实施例中，通信装置可在第二时段到来前，预测第二时段内第一小区的RRC连接用户数，其中预测的第二时段内第一小区的RRC连接用户数，用于配置第二时段内第一小区的SRS周期，即在第二时段内接入第一小区的终端设备发送SRS信号的周期。
具体的，通信装置可通过如下方式预测第二时段内第一小区的RRC连接用户数：
针对第一时段内的每个时刻，通信装置将第一小区的至少一个邻区在该时刻的RRC连接用户数进行求和，得到求和值，进而，将第一时段中包括的各个时刻对应的求和值中的最大值，作为预测的第二时段内第一小区的RRC连接用户数。
也就是说，假设在第一时段中，第一小区的至少一个邻区的RRC连接用户数之和在第一时刻达到最大值，那么预测的第一小区在第二时段内的RRC连接用户数为，第一小区的至少一个邻区在第一时刻对应的RRC连接用户数之和，即第一小区的至少一个邻区 的RRC连接用户数之和的最大值。可以理解，该至少一个邻区在第一时刻对应的RRC连接用户数之和大于或等于该至少一个邻区在第一时段内的其他时刻对应的RRC连接用户数之和。
应理解，本申请实施例中，第一时段位于第二时段之前，第一时段可以与第二时段相邻，也可以不相邻。第一时段与第二时段的关系可以由通信装置配置，也可以是预定义或预配置的，本申请并不限定。此外，第一时段与第二时段的时长可以相同或不同，本申请也不限定。
步骤S203、通信装置根据预测的第一小区在第二时段内的RRC连接用户数，为在第二时段内接入第一小区的终端设备配置SRS周期。
具体的，该通信装置根据预测的第一小区在第二时段内的RRC连接用户数，以及RRC连接用户数与SRS周期之间的映射关系，为在第二时段内接入第一小区的终端设备配置SRS周期。该RRC连接用户数与SRS周期之间的映射关系可以是通信装置配置的，也可以是预定义或预配置的，还可由通信装置根据需要适时调整，本申请并不限定。
采用上述技术方案，通信装置可在第二时段到来前，根据第一时段内第一小区的至少一个邻区的RRC连接用户数，预测第二时段内第一小区的RRC连接用户数，进而为在第二时段内接入第一小区的终端设备配置SRS周期。由此可知，通信装置可预先为第一小区配置第二时段内可用的SRS周期，在第二时段内无需重新配置，从而可避免SRS周期调整过于频繁的问题，有效降低SRS周期配置的信令开销。同时，又可使配置的SRS周期符合第一小区在第二时段内的接入情况。
进一步地，本申请实施例中，通信装置可以第二时段的时长为周期，周期性地配置第一小区的SRS周期，即通信装置可每经过一个第二时段的时长为第一小区配置一次SRS周期，相应地，上述步骤S201至步骤S203可以第二时段的时长为单位重复地执行，每经过一次第二时段的时长就执行一次。如此，可使得第一小区的SRS周期可以被及时调整，以满足终端设备的通信需求。
本申请实施例提供的技术方案还可应用于高速场景下，例如图3所示的高铁场景。高速场景下，终端设备具有高速移动、快速切入切出小区、以及批量切入切出小区等特征。由于终端设备的高速移动，小区内的RRC连接用户数也有可能快速变化。若根据实时统计的RRC用户数配置SRS周期，则有可能因信令时延的存在，SRS周期的配置速度跟不上终端设备的移动速度，而使得SRS周期配置不准确，需要进行反复的重配。而本申请实施例中，由于可根据在第二时段之前的第一时段内，第一小区的至少一个邻区的最大RRC连接用户数之和，来预测第二时段内第一小区的用户数，因此可得到在第二时段内可能接入第一小区的最大RRC连接用户数，根据该最大的RRC连接用户数来配置第二时段内的SRS周期，可有效避免当大量终端设备在第二时段内批量接入第一小区时，部分终端设备因分配不到SRS资源而产生掉话的问题。
举例来说，如图3所示，第一小区部署在高铁沿线，其RRC连接用户数呈现出如图4所示的变化规律，即当高速列车经过时，大量终端设备快速地切入小区，第一小区内的RRC连接用户数快速达到峰值，在高速列车经过后，第一小区内的RRC连接用户数又快速地恢复到较低水平，且保持基本稳定。
采用本申请实施例提供的技术方案，通信装置可根据第一小区的小区属性、列车时刻表、以及列车载客量等信息，将第二时段的时长设置为一辆高速列车经过第一小区所需的 平均时间，将第一时段的时长设置为小于第一小区中时间相邻的两辆高速列车之间的最小发车间隔。
通信装置还可以第二时段的时长为单位周期性的配置第一小区的SRS周期，具体的：通信装置可在每个第二时段到来前，将第二时段之前的一段时间确定为第一时段，计算第一时段内第一小区的各个邻区的RRC连接用户数的之和的最大值。例如，第二时段的时长可以为15s，第一时段可以为第二时段之前的15s、10s或5s的时间，每当一个第二时段将要到来时，通信装置可获取第一小区的各个邻区在第二时段之前的前15s、10s或5s的时间中RRC连接用户数。随后，通信装置将该第一时段内第一小区的各个邻区的RRC连接用户数的之和的最大值，确定为预测的第二时段内第一小区的RRC连接用户数。进而，通信装置可根据该预测的第二时段内第一小区的RRC连接用户数，为第二时段内接入第一小区的终端设备配置SRS周期。
如图5所示，第一小区与第一小区的各个邻区在地理位置上距离较近，经过第一小区的邻区的列车也有可能经过第一小区，即高铁场景下，当第一小区的邻区有列车经过时，第一小区的邻区的RRC连接用户数可能会快速地传递到第一小区，并导致第一小区中的RRC连接用户数激增。如此，通过计算在第二时段之前的第一时段中第一小区的至少一个邻区的RRC连接用户数之和，预测第二时段中第一小区的RRC连接用户数，并根据该预测的第二时段中第一小区的RRC连接用户数提前配置第二时段中第一小区的SRS周期，可有效避免因SRS周期的调整速度跟不上列车的移动速度，而导致SRS周期的配置不及时以及重配置信令开销太大的问题，从而满足终端设备的移动性需求。
在一种可能的设计中，本申请实施例中，该通信装置还可实时统计第一小区中的RRC连接用户数，并向第一小区的至少一个邻区周期性地发送该统计的第一小区的RRC连接用户数，统计的该第一小区的RRC连接用户数可用于邻区配置SRS周期。相应的，在步骤S201中，第一小区的各个邻区也可实时统计自己小区中的RRC连接用户数，并周期性地发送给第一小区，以便于通信装置利用邻区统计的RRC连接用户数，执行步骤S201至步骤S203，为第一小区配置SRS周期。应理解，第一小区的各个邻区向第一小区发送统计的RRC连接用户数的周期与第一时段的时长、第二时段的时长可以相同或不同，本申请并不限定。
实施例二
请参考图6，为本申请实施例提供的另一种探测参考信号SRS周期的配置方法的流程示意图，该方法包括如下步骤：
步骤S601、通信装置获取第一小区的RRC连接用户数在一个变化周期内的历史统计数据，该变化周期包括多个时段，该历史统计数据包括第一小区在变化周期内的每个时段的RRC连接用户数。
本申请实施例中，第一小区的RRC连接用户数可具有周期性的变化规律，所述第一小区的RRC连接用户数在一个变化周期内的历史统计数据可用于反映该第一小区的RRC连接用户数的变化规律，所述变化周期可以理解为第一小区的RRC连接用户数周期性变化的周期。
具体的，该第一小区的RRC连接用户数在一个变化周期内的历史统计数据可通过如下方式得到：
首先，通信装置可获取第一小区在过去的设定时长范围内的RRC连接用户数。为了获得足够的历史数据来提炼第一小区的RRC连接用户数的变化规律，该设定时长范围可设置的较长，例如可设置为过去的1个月、2个月甚至半年等。应理解，该设定时长范围可由通信装置配置，或者也可以是预定义或与配置的，本申请并不限定。
随后，通信装置可根据第一小区在过去的设定时长范围内的RRC连接用户数，确定RRC连接用户数的变化周期，所述设定时长范围包括多个变化周期。该步骤也可以理解为，确定第一小区的RRC连接用户数周期性变化的周期，例如，该变化周期可以为1天、2天、3天、1周、2周等。若变化周期为1周，则可表示第一小区的RRC连接用户数在各周的变化情况是相同或类似的。
进而，针对一个变化周期中的每个时段，通信装置可根据第一小区在设定时长范围内包括的多个变化周期中的该时段的RRC连接用户数，确定历史统计数据中第一小区在该时段的RRC连接用户数。例如，在一种可能的实现方式中，通信装置可将第一小区在所述设定时长范围内包括的多个变化周期中的该时段的RRC连接用户数的平均值，确定为历史统计数据中第一小区在该时段的RRC连接用户数；或者，在另一种可能的设计中，通信装置也可对第一小区在所述设定时长范围内包括的多个变化周期中的该时段的RRC连接用户数进行数据滤波(如ALPHA滤波法)，得到历史统计数据中第一小区在该时段的RRC连接用户数；再或者，在另一种可能的设计中，通信装置还根据第一小区在所述设定时长范围内包括的多个变化周期中该时段的RRC连接用户数的累积分布曲线(CDF曲线)，确定历史统计数据中该第一小区在该时段的RRC连接用户数，例如可根据第一小区在所述设定时长范围内包括的多个变化周期中该时段的RRC连接用户数绘制CDF曲线，冉从将取该CDF曲线中x％点对应的值，作为历史统计数据中第一小区在该时段的RRC连接用户数。
为了精确地体现第一小区的RRC连接用户数的变化规律，本申请实施例中，通信装置可将第一小区的RRC连接用户数的一个变化周期划分为多个时段，一个时段可以理解为第一小区的RRC连接用户数的统计数据在时间上的统计粒度，即一个时段对应一个第一小区的RRC连接用户数的统计数据。例如一个变化周期可以为1周，一个时段为15分钟，通信装置可将一个变化周期按照每15分钟的时间粒度划分为多个时段，并逐一确定每个时段对应的第一小区的连接用户数的统计数据。
如此，通信装置可得到一个变化周期中的各个时段的第一小区的RRC连接用户数，从而得到第一小区的RRC连接用户数在一个变化周期内的历史统计数据，即第一小区的RRC连接用户数的变化规律。该第一小区的RRC连接用户数的变化规律也可以表现为如图7所示的函数曲线的形式，也可以为数据表格或者其他的图表的形式，本申请并不限定。
步骤S602、通信装置根据第一小区在变化周期中与第三时段处于相同位置的时段的RRC连接用户数，预测第一小区在第三时段的RRC连接用户数。
步骤S603、通信装置根据预测的第一小区在第三时段的RRC连接用户数，为在第三时段内接入第一小区的终端设备配置SRS周期。
举例来说，通信装置要配置第三时段内第一小区的SRS周期，若第一小区的RRC连接用户数的变化周期为1周，一个时段为15分钟，第三时段为某个周一的上午10:00分至10:15分，那么通信装置可在第三时段到来前，根据第一小区的RRC连接用户数在一个变化周期中的历史统计数据，将该历史统计数据中周一的上午10:00分至10:15分对应的第 一小区的RRC连接用户数，确定为预测的第三时段中的第一小区的RRC连接用户数，进而根据该预测的第三时段中的第一小区的RRC连接用户数，为在第三时段内接入第一小区的终端设备配置SRS周期。
采用上述技术方案，通信装置可在第三时段到来前，根据第一小区的RRC连接用户数的历史变化规律来预测第三时段内第一小区的RRC连接用户数，从而为第三时段内接入第一小区的终端设备配置SRS周期。由此可知，通信装置可预先为第一小区配置第三时段内可用的SRS周期，在第三时段内无需重新配置，从而可避免SRS周期调整过于频繁的问题，有效降低SRS周期配置的信令开销。同时，又可使配置的SRS周期符合第一小区在第三时段内的接入情况。
需要说明的是，本申请实施例提供的两种配置SRS周期的方法可以理解为两种配置SRS周期的方式，通信装置可根据第一小区的小区属性，确定第一小区所处的应用场景，进而选择为第一小区配置SRS周期的方式。例如，若第一小区部署在高铁沿线，那么考虑到第一小区中终端设备可能高速移动并批量地切入切出，那么通信装置可采用实施例一中所述的配置的SRS周期的方法；若第一小区部署在大型公共场所中(例如体育场、校园、教师、车站、红绿灯等场景)，那么考虑到第一小区中可能存在着短时间内大量用户集体切入切出，但不会高速移动，通信装置可采用实施例二中所述的配置的SRS周期的方法。应理解，上述两个实施例中所描述的技术特征也可以相互结合使用，本申请并不限定。
本申请实施例还提供一种通信装置，请参阅图8，为本申请实施例提供的一种通信装置的结构示意图，该通信装置800包括：收发模块810和处理模块820。该通信装置可用于实现上述任一方法实施例中涉及通信装置的功能。例如，该通信装置可以是网络设备或网络设备中包括的芯片。

在一种可能的设计中，每个邻区在第一时段内的无线资源控制RRC连接用户数包括该邻区在第一时段内的每个时刻的RRC连接用户数；预测的第一小区在第二时段内的RRC连接用户数为：第一小区的至少一个邻区在第一时段内的第一时刻的RRC连接用户数之和，该至少一个邻区在第一时刻的RRC连接用户数之和大于或等于该至少一个邻区在第一时段内的其他时刻的RRC连接用户数之和。
在一种可能的设计中，处理模块820具体用于，根据预测的第一小区在第二时段内的RRC连接用户数，以及RRC连接用户数与SRS周期之间的映射关系，为在第二时段内接入第一小区的终端设备设置SRS周期。
在一种可能的设计中，处理模块820还用于，可实时统计第一小区的RRC连接用户数；收发模块810还用于周期性地向第一小区的至少一个邻区发送统计的第一小区的RRC连接用户数，实时统计的第一小区的RRC连接用户数用于每个邻区配置SRS周期。
应理解，该通信装置中涉及的处理模块820可以由处理器或处理器相关电路组件实现，收发模块810可以由收发器或收发器相关电路组件实现。该通信装置中的各个模块的操作 和/或功能分别为了实现图2中所示方法的相应流程，为了简洁，在此不再赘述。
