Description

一种参考信号发送方法及其装置

技术领域
本发明涉及通信领域，尤其涉及一种参考信号发送方法及其装置。
背景技术
无线资源管理(Radio Resource Management，RRM)：是在有限带宽的条件下，为网络内无线用户终端提供业务质量保障，其基本出发点是在网络话务量分布不均匀、信道特性因信道衰弱和干扰而起伏变化等情况下，灵活分配和动态调整无线传输部分和网络的可用资源，最大程度地提高无线频谱利用率，防止网络拥塞和保持尽可能小的信令负荷。RRM包括功率控制、信道分配、调度、切换、接入控制、负载控制和自适应编码调制等。
目前，在长期演进(Long Term Evolution，LTE)系统中，RRM中的小区切换采用基于下行参考信号的测量方式，即基站向其覆盖范围内的用户设备(User Equipment，UE)发送参考信号(Reference signal，RS)，通常发送固定时频资源的公共参考信号(Common Reference signal，CRS)；某个UE在接收到该基站发送的CRS时，根据CRS进行测量，并向该基站上报测量结果；该基站在接收到该UE反馈的测量结果时，根据测量结果判断该UE是否需要进行小区切换。
UE在通信过程中，可能处于移动状态，可能从小区的中心位置移动到小区的边缘位置或从小区的边缘位置移动到小区的中心位置，但是在这些情况下，基站依然向UE发送CRS，换言之，基站配置发送方式固定，在一定程度上增加CRS开销。

具体实施方式
下面结合本发明实施例中的附图对本发明实施例进行描述。
请参见图1a，为举例地可以应用本发明实施例的一种网络架构示意图，该网络架构示意图可以是LTE通信系统的网络架构，也可以是通用移动通信系统(Universal Mobile Telecommunications System，UMTS)陆地无线接入网(UMTS Terrestrial Radio Access Network，UTRAN)架构，或者全球移动通信系统(Global System for Mobile Communications，GSM)/增强型数据速率GSM演进(Enhanced Data Rate for GSM Evolution，EDGE)系统的无线接入网(GSM EDGE Radio Access Network，GERAN)架构，甚至还可以是第五代移动通信(5th-Generation，5G)系统架构。该网络架构示意图包括移动性管理实体(Mobility Management Entity，MME)/服务网关(Serving Gate Way，SGW)、基站和用户设备(User Equipment，UE)。需要说明的是，图1a所示的MME/SGW、基站和UE的形态和数量用于举例说明，并不构成对本发明实施例的限定。
其中，MME是第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)LTE中的关键控制节点，属于核心网网元，主要负责信令处理部分，即控制面功能，包括接入控制、移动性管理、附着与去附着、会话管理功能以及网关选择等功能。SGW是3GPP LTE中核心网网元的重要网元，主要负责用户设备数据转发的用户面功能，即在MME的控制下进行数据包的路由和转发。
其中，基站用于与用户设备进行通信，可以是GSM系统或码分多址接入(Code Division Multiple Access，CDMA)中的基站(Base Transceiver Station，BTS)，也可以是WCDMA系统中的基站(Node B，NB)，还可以是LTE系统中的演进型基站(Evolutional Node B，eNB)，甚至还可以是5G系统中的基站以及未来通信系统的基站。基站主要负责空口侧的无线资源管理、服务质量(Quality of Service，QoS)管理、数据压缩和加密等功能。针对核心网侧，基站主要负责向MME转发控制面信令以及向SGW转发用户面业务数据。
其中，用户设备是通过基站接入网络侧的设备，可以包括但不限于蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，未来5G网络中的终端设备等。
图1a所示的S1接口，为基站与核心网之间的标准接口。其中，基站通过S1-MME接口与MME连接，用于控制信令的传输；基站通过S1-U接口与SGW连接，用于用户设备数据的传输。其中，S1-MME接口和S1-U接口统称为S1接口。
图1a所示的X2接口，为基站与基站的标准接口，用于实现基站之间的互通。
图1a所示的Uu接口，为用户设备与基站之间的标准接口，用户设备通过Uu接口接入到LTE/5G网络。
请参见图1b，为举例地可以应用本发明实施例的另一种网络架构示意图，该网络架构示意图可以是下一代无线通信系统中的新空口(New Radio，NR)的网络架构图。在该网络架构示意图中，一个基站被分为一个集中式单元(Centralized Unit，CU)和多个传输接 收点(Transmission Reception Point，TRP)/分布式单元(Distributed Unit，DU)，即基站的基于带宽的单元(Bandwidth Based Unit，BBU)被重构为DU和CU功能实体。需要说明的是，图1b所示的集中式单元、TRP/DU的形态和数量用于举例说明，并不构成对本发明实施例的限定。图1b所示的基站1和基站2各自对应的集中式单元的形态虽然有所不同，但是并不影响各自的功能。可以理解的是，集中式单元1和虚线范围内的TRP/DU是基站1的组成元素，集中式单元2和实线范围内的TRP/DU是基站2的组成元素，基站1和基站2为NR系统中涉及的基站。
其中，CU处理无线高层协议栈功能，例如无线资源控制(Radio Resource Control，RRC)层，分组数据汇聚层协议(Packet Data Convergence Protocol，PDCP)层等，甚至也能够支持部分核心网功能下沉至接入网，术语称作边缘计算网络，能够满足未来通信网络对于新兴业务例如视频，网购，虚拟/增强现实对于网络时延的更高要求。
其中，DU主要处理物理层功能和实时性需求较高的层2功能，考虑到无线远端单元(Radio Remote Unit，RRU)与DU的传输资源，部分DU的物理层功能可以上移到RRU，伴随RRU的小型化，甚至更激进的DU可以与RRU进行合并。
CU可以集中式的布放，DU布放取决实际网络环境，核心城区，话务密度较高，站间距较小，机房资源受限的区域，例如高校，大型演出场馆等，DU也可以集中式布放，而话务较稀疏，站间距较大等区域，例如郊县，山区等区域，DU可以采取分布式的布放方式。
图1b所示的S1-C接口，为基站与核心网之间的标准接口，具体S1-C所连接的设备未在图1b中示出。
基于图1a或图1b所示的网络架构示意图，目前采用的基于下行信号的测量方式为：基站或TRP向其覆盖范围内的UE发送CRS；UE在接收到CRS时，根据CRS进行测量，并向基站或TRP上报测量结果；基站或TRP在接收到UE反馈的测量结果时，根据测量结果判断该UE是否需要进行小区切换。不管UE如何移动，基站或TRP依然向UE发送CRS，换言之，基站或TRP配置发送方式固定，在一定程度上增加CRS开销。
鉴于此，本发明实施例提供一种参考信号发送方法及其装置，可以实现网络设备灵活配置参考信号，可以节省网络设备的参考信号开销。本发明实施例中的参考信号可以是用于测量的参考信号，可以是用于小区间或小区内移动性测量的参考信号。各个实施例中不再赘述。下文中将针对参考信号为小区特定参考信号或用户设备特定参考信号或用户设备组特定参考信号进行介绍。
相应地，本发明实施例还提供一种参考信号接收方法及其装置，接收小区特定参考信号或用户设备特定参考信号或用户设备组特定参考信号，并根据小区特定参考信号或用户设备特定参考信号或用户设备组特定参考信号进行测量，可以提高测量结果的准确性。
本发明实施例提供的参考信号发送方法及其装置、参考信号接收方法及其装置可以应用于图1a或图1b所示的网络架构示意图中。本发明实施例中的网络设备可以是图1a所示的基站，也可以是图1b所示的TRP/DU，还可以是TRP/DU与CU的组合。本发明实施例中的用户设备可以包括但不限于蜂窝电话、无绳电话、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，未来5G网络中的终端设备等。本发明实施例提供的参考信号发送方法、参考信号接收方法可以应用于 用户设备处于连接态的情况。
下面将对本发明实施例提供的参考信号发送方法进行详细介绍。
请参见图2a，为本发明实施例一提供的参考信号发送方法流程示意图，该方法包括但不限于如下步骤：
步骤S101：网络设备发送小区特定参考信号的配置信息；
其中，所述cell specific参考信号的配置信息用于指示所述cell specific参考信号的空口发送信息，其中空口发送信息可以包括端口(port)数量、port位置、时频资源映射规则、发送周期、时间偏移量、带宽等信息中的一种或多种，换言之，所述cell specific参考信号的配置信息指示所述cell specific参考信号在哪些port上发送，占用哪些时频资源，以及其时间配置信息(发送周期、时间偏移量等)。其中，port数量指示占用了多少个port，例如1，2，4等；port位置指示占用哪些port，例如port 1、port 2等，port数量和port位置联合指示发送所述cell specific参考信号的端口信息。
其中，所述cell specific参考信号表示基于小区的参考信号，针对同一小区的每个波束(beam)，采用的参考信号都相同；或者，针对同一小区的参考信号都是采用相同的配置。所述cell specific参考信号可以为cell specific信道状态信息参考信号(Channel State Information-Reference Signal，CSI-RS)，也可以为测量参考信号(Measurement Reference Signal，MRS)，还可以为移动参考信号(Mobility Reference Signal，MRS)，还可以为物理广播信道(Physical Broadcast Channel，PBCH)的解调参考信号(Demodulation Reference Signal，DM-RS)。
若所述cell specific参考信号为所述cell specific CSI-RS，则其时频资源配置情况可以举例参见图3所示，为4端口的CSI-RS的时频资源配置示意图，cell specific CSI-RS与CSI-RS的配置类似，图3中横向表示时间维度，一帧，两个时隙，14个符号；纵向表示频率维度，12个子载波。图3中灰色阴影区域所示的3列表示为UE分配的带宽资源，斜线区域或竖线区域所示的部分表示配置CSI-RS所占用的时频资源。所述cell specific CSI-RS的时间配置信息可参见图4所示的CSI-RS的子帧配置表，图4中配置周期即为发送周期，子帧偏移量即为时间偏移量。
所述cell specific参考信号的空口发送信息还包括资源块位置信息，指示所述cell specific参考信号配置在同步信号块(Synchronization Signal block，SS block)中还是配置在测量块(measurement block)中。所述网络设备可将所述cell specific参考信号配置在SS block中或配置在measurement block中。测量块可以是一种新定义的资源块，用于传输用于测量的参考信号。当然，测量块也可以不叫做测量块，可以叫做其他名字，只要功能包括传输用于测量的参考信号就可以。所述网络设备可在一个或多个SS block上配置所述cell specific参考信号，或在一个或多个measurement block上配置所述cell specific参考信号，视具体情况而定。
其中，SS block中存在同步信号，反之measurement block中可以不存在同步信号。SS block中除配置有同步信号之外，还可配置其它参考信号，measurement block可配置用于UE测量的参考信号。SS block、measurement block的时频资源结构可以举例地与LTE系统中的时频资源结构相同，时间维度上有14个符号，表示一帧，频率维度上有12个子载波。 时频资源上SS block和measurement block的数量在此不作限定。
若所述网络设备将所述cell specific参考信号配置在SS block中，则可以无需告知UE，比如通过标准规定，SS block中一些资源是用于传输用于同步的参考信号，一些资源用于传输用于测量的参考信号，因为SS block中配置有用于同步的参考信号，UE需根据用于同步的参考信号进行同步，若还配置有其它参考信号，则UE在获取到SS block时可以获知存在其它参考信号。所述网络设备可将所述cell specific参考信号配置在measurement block中，进一步可选地，还可以在measurement block中配置其他类型参考信号，比如UE specific参考信号，进一步可选地，还可以在measurement block中配置用于同步的参考信号参考信号。
所述网络设备向所述网络设备所属小区内的所有用户设备发送所述cell specific参考信号的配置信息，或广播例如通过PBCH广播所述cell specific参考信号的配置信息。
若所述cell specific参考信号为所述cell specific CSI-RS或为MRS，则所述网络设备向所述网络设备所属小区内的所有用户设备发送所述cell specific CSI-RS的配置信息或者所述网络设备广播例如通过PBCH广播所述cell specific CSI-RS的配置信息，或所述网络设备向所述网络设备所属小区内的所有用户设备发送所述MRS的配置信息或者所述网络设备广播例如通过PBCH广播所述MRS的配置信息。可以理解的是，针对某个TRP所属小区内的所有UE的cell specific参考信号的配置信息相同。
可选地，所述网络设备向所述网络设备所属小区内的所有用户设备发送或所述网络设备广播例如通过PBCH广播所述cell specific CSI-RS的模式索引(pattern index)。例如3个比特的pattern index可以表示8种cell specific CSI-RS的方案，其中每种cell specific CSI-RS的方案对应着一种配置信息。例如，UE在接收到广播消息时，获取pattern index，根据该pattern index对应的cell specific CSI-RS的方案的时频资源对cell specific CSI-RS进行测量。
步骤S102：所述网络设备根据所述小区特定参考信号的配置信息发送所述小区特定参考信号；
具体地，所述网络设备根据所述cell specific参考信号的配置信息发送所述cell specific参考信号，即根据所配置的端口、时频资源映射规则、资源块等信息发送所述cell specific参考信号。

具体地，所述用户设备为所述网络设备所属小区内的任意一个用户设备。
在一种可能实现的方式，所述用户设备可通过广播消息接收所述网络设备发送的所述cell specific CSI-RS的配置信息或所述MRS的配置信息，即所述cell specific CSI-RS的配置信息或所述MRS的配置信息携带在广播消息中。
在一种可能实现的方式，所述用户设备通过RRC信令接收所述网络设备发送的所述UE group specific CSI-RS的配置信息，即所述UE group specific CSI-RS的配置信息携带在RRC信令中。
所述用户设备在接收到所述cell specific参考信号的配置信息时，获取所述cell specific参考信号的配置信息，以便接收所述cell specific参考信号。
步骤S104：所述用户设备根据接收所述小区特定参考信号；
具体地，所述用户设备根据所述cell specific参考信号的配置信息接收所述cell specific参考信号。接收参考信号的过程可以理解为根据地图查找建筑的过程，所述cell specific参考信号的配置信息类比于地图，所述cell specific参考信号类比于建筑。
步骤S105：所述用户设备根据所述小区特定参考信号进行测量；
具体地，所述用户设备根据SS block或measurement block中的所述cell specific参考信号进行测量，得到测量结果。所述测量结果可以包括参考信号接收功率(Reference Signal Received Power，RSRP)、参考信号接收质量(Reference Signal Received Quality，RSRQ)、接收信号强度指示(Received Signal Strength Indicator，RSSI)等结果中的至少一种。具体的测量方法在此不作限定。
本发明实施例一，通过网络设备配置并发送cell specific参考信号，由于cell specific参考信号配置是基于小区级别的参考信号配置，因此可以节省网络设备的参考信号开销。
