具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本申请。下文中将结合附图对本申请的实施例进行详细说明。
随着无线通信技术的迅猛发展，低频段资源日益紧张，而具有更多频谱资源和带宽的毫米波频段将成为未来无线通信系统的重要频段。但是，毫米波频段波长较短，其传播条件比传统的6GHz以下频段要苛刻得多，存在路径损耗高和对阻塞敏感等问题。为此，毫米波信号通常需要进行波束赋型，将信号能量集中在一个小的角空间内以形成增益更大的赋性波束。波束管理通过建立和维护一个合适的波束对，实现发送端和接收端波束方向的对齐，从而获得最佳的传输性能。波束管理对毫米波通信系统至关重要，包括波束扫描、波束测量、波束上报和波束指示等。
波束扫描是指基站或用户设备(User Equipment，UE)依次使用不同的模拟波束覆盖一个空间区域的过程。在波束扫描期间，基站或UE顺序地发送来自整个码本或码本子集的波束，以便为数据和控制通道找到良好的收发波束对。波束扫描过程主要包括发送端波束扫描P-2过程和接收端波束扫描P-3过程。
图1示出了一种P-2波束管理过程的示意图。如图1所示，假设基站为下一代基站(next generation NodeB，gNB)，在P-2波束管理过程中，gNB配置高层参数资源集非零功率信道状态信息参考信号资源集(Non-Zero Power-CSI-RS-ResourceSet，NZP-CSI-RS-ResourceSet)，每个资源集中包含多个采用不同发送波束传输的信道状态信息参考信号(Channel State Information-Reference Signal，CSI-RS)或单边带(Single Side Band，SSB)资源，UE采用固定接收波束接收和测量CSI-RS或SSB资源，以完成发送端波束测量过程。此外，如果gNB没有提供UE侧接收波束的辅助信息，UE可能需要轮巡接收波束，即用于波束管理的CSI-RS资源集合重复传输多次，UE分别使用不同的接收波束进行接收，从而实现接收波束的扫描。
图2示出了一种P-3波束管理过程的示意图。如图1所示，假设基站为gNB，在P-3波束管理过程中，gNB配置高层参数资源集NZP-CSI-RS-ResourceSet，每个资源集中包含多个采用相同发送波束传输的CSI-RS或SSB资源，UE采用不同接收波束接收和测量CSI-RS或SSB资源，以实现接收波束的扫描。此外，gNB可能需要轮巡发送波束，即配置多个采用不同发送波束传输的CSI-RS资源集合，来实现发送波束的扫描。
由于波束通常是从预先确定的模拟波束码本中选择的，因此，对码本中所有发射波束和接收波束进行穷尽扫描是一种最优的波束训练方案。然而，这可能会导致过高的训练开销、测量功耗和处理延时。
本申请提供的信令的发送、接收方法可以应用于各类无线通信系统中，例如长期演进(long term evolution，LTE)系统、第四代移动通信技术(4th-generation，4G)系统、第五代移动通信技术(5th-generation，5G)系统、LTE与5G混合架构系统、5G新无线电(New Radio，NR)系统、以及未来通信发展中出现的新的通信系统，如第六代移动通信技术(6th-generation，6G)系统等。图3示出了一实施例提供的一种无线通信系统的组网示意图。如图3所示，该无线通信系统包括终端设备110、接入网设备120和核心网设备130。
终端设备110可以是一种具有无线收发功能的设备，可以部署在陆地上(如室内或室外、手持、穿戴或车载等)；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星等)。一些终端设备110的举例为：UE、手机、移动台、平板电脑、笔记本电脑、超级移动个人计算机(Ultra-mobile  Personal Computer，UMPC)、手持计算机、上网本、个人数字助理(Personal Digital Assistant，PDA)等可以联网的用户设备，或虚拟现实(Virtual Reality，VR)终端、增强现实(Augmented Reality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等，或物联网中的物联网节点，或车联网中的车载通信装置，或娱乐、游戏设备或系统，或全球定位系统设备等。本申请的实施例对终端设备110所采用的技术和设备形态不做限定，另外，终端设备110可以简称终端。
接入网设备120是终端设备110通过无线方式接入到该无线通信系统中的接入设备，可以是基站(base station)、长期演进增强(Long Term Evolution Advanced，LTEA)中的演进型基站(evolved NodeB，eNB或eNodeB)、发送接收点(transmission reception point，TRP)、5G移动通信系统中的基站或gNB、未来移动通信系统中的基站或无线保真(Wireless Fidelity，WiFi)系统中的接入节点等。基站可以包括各种宏基站、微基站、家庭基站、无线拉远、路由器、WIFI设备或者主小区(primary cell)和协作小区(secondary cell)等各种网络侧设备、定位管理功能(Location Management Function，LMF)设备。也可以是完成基站部分功能的模块或单元，例如，可以是集中式单元(central unit，CU)，也可以是分布式单元(distributed unit，DU)。本申请的实施例对接入网设备所采用的技术和设备形态不做限定，另外，接入网设备可以简称基站。
核心网设备130可以包括接入与移动性管理网元和会话管理网元。示例性地，终端设备110可以通过接入网设备120接入核心网，从而实现数据传输。
在本申请实施例中，提供一种可运行于上述无线通信系统的信令的发送、接收方法，通信节点及存储介质，相比于传统的穷尽扫描方法，本申请只需要发送或测量部分时刻的波束，预测其他时刻的波束，从而减小在时域上的波束训练开销、提升波束对齐精度，在更小的波束训练开销情况下获得理想的波束赋形增益和频谱效率。
下面，对信令的发送方法、信令的接收方法，通信节点及其技术效果进行描述。
图4示出了一实施例提供的一种信令的发送方法的流程示意图，如图4所示，本实施例提供的方法适用于第一通信节点。在本示例中，第一通信节点(也可以称为第一通信节点设备)可以是基站，第二通信节点(也可以称为第二通 信节点设备)可以是终端设备。该方法包括。

S120、接收第二通信节点上报的CSI信息以及时间戳信息。
在一实施例中，在S120执行之前，第一通信节点还可以向第二通信节点发送第二信令，第二信令用于指示第二通信节点的接收波束保持不变。其目的在于：如果第二通信节点的接收波束发生改变，可能会导致第二通信节点上报的CSI信息以及时间戳信息失效。
在一实施例中，本申请上述实施例的共性在于一些时刻不需要发送CSI-RS资源。因此，对于半持续的(semi-persistent)CSI-RS资源或半持续的CSI上报，第一通信节点还可以向第二通信节点发送第三信令，第三信令用于指示一次波束预测过程中的激活周期和去激活周期中的至少之一。

在第一个示例性实施方式中，假设由基站实现基于AI的波束预测，对于CSI reporting setting，基站向UE发送第一信令，第一信令用于指示UE上报一 个或多个时间戳上的CSI信息以及时间戳信息。UE根据第一指令，向基站上报CSI信息以及时间戳信息，以减少上报次数。其中，CSI信息包括以下至少之一：RSRP、CRI、RSRQ、参考信号接收信号、SINR、SNR；时间戳信息包括以下至少之一：时隙索引或时隙编号、子帧索引或子帧编号、符号索引或符号编号。
例如，图6示出了一实施例提供的一种波束预测示意图。如图6所示，假设周期CSI-RS的发送时隙索引为1，2，3，…(即周期为1)，一个CSI-RS资源子集周期包括5个时隙索引，即CSI-RS子集周期的重复数量为5。基站指示UE上报时隙1，2，3上的CSI信息，故而UE向基站上报时隙1上的CSI信息(如CRI/RSRP)以及对应的时隙索引1、时隙2上的CSI信息(如CRI/RSRP)以及对应的时隙索引2，时隙3上的CSI信息(如CRI/RSRP)以及对应的时隙索引3，以使得基站据此预测时隙索引4，5的最优波束。
又例如，图7示出了一实施例提供的另一种波束预测示意图。如图7所示，假设周期CSI-RS的发送时隙索引为1，2，3，…(即周期为1)，一个CSI-RS周期包括1个时隙索引。基站指示UE上报时隙1，3，5上的CSI信息，故而UE向基站上报时隙1上的CSI信息(如CRI/RSRP)以及对应的时隙索引1、时隙3上的CSI信息(如CRI/RSRP)以及对应的时隙索引3，时隙5上的CSI信息(如CRI/RSRP)以及对应的时隙索引5，以使得基站据此预测时隙索引6的最优波束。
或者，基站指示UE上报时隙3，5，7上的CSI信息，故而UE向基站上报时隙3上的CSI信息(如CRI/RSRP)以及对应的时隙索引3、时隙5上的CSI信息(如CRI/RSRP)以及对应的时隙索引5，时隙7上的CSI信息(如CRI/RSRP)以及对应的时隙索引7，以使得基站据此预测时隙索引8的最优波束。以此类推。
同理，假设由UE实现基于AI的波束预测，以图6所示的波束预测示意图为例，基站指示UE上报时隙4，5上的CSI信息，故而UE根据时隙1上的CSI信息(如CRI/RSRP)以及对应的时隙索引1、时隙2上的CSI信息(如CRI/RSRP)以及对应的时隙索引2，时隙3上的CSI信息(如CRI/RSRP)以及对应的时隙索引3，预测时隙索引4，5的最优波束。随后UE将预测得到的时隙4上的CSI信息(如CRI/RSRP)以及对应的时隙索引4、时隙5上的CSI信息(如CRI/RSRP)以及对应的时隙索引5上报给基站。
在一实施例中，UE上报的CRI/RSRP可以为一个或多个时间戳上的最强CRI/RSRP，也可以为一个或多个时间戳上的强度位于前K位的CRI/RSRP，K≥2、且K为整数。此外，UE还上报固定CRI或固定发送波束或固定发送接收波束对情况下的CRI/RSRP，以跟踪UE的移动轨迹，辅助AI预测。
在整个时域波束预测过程(多个测量周期)中，基站通过高层信令指示UE 接收波束保持不变。否则，可能导致上报的CRI/RSRP没有意义。
在第二个示例性实施方式中，结合第一个示例性实施方式可知，上述实施例的共性在于一些时刻不需要发送CSI-RS资源。由于基于循环神经网络(Recurrent Neural Network，RNN)的AI模型具有确定长度的输入输出，假设定义AI模型的输入为M个周期的最优波束索引，输出为未来N个周期的最优波束索引。因此，对于半持续的CSI-RS资源或半持续的CSI上报，基站还可以向UE发送第三信令，第三信令用于指示一次波束预测过程中的激活周期和去激活周期中的至少之一，即指定媒体控制-控制单元(Media Access Control control element，MAC CE)激活周期和去激活周期中的至少之一。
第三信令可以采用如下三种方式中的任一方式指示：
1)若激活周期和去激活周期为连续周期，则第三信令包括激活周期数M和去激活周期数N中的至少之一，N，M为正整数。
在该方式中，第三信令包括激活周期数M和去激活周期数N中的至少之一，即激活M个周期后自动去激活；或者去激活N个周期后自动重新激活；或者激活M个周期后自动去激活N个周期(即激活一次时域波束预测过程)。
图8示出了一实施例提供的一种激活周期和去激活周期的示意图。如图8所示，假设周期CSI-RS的发送时隙索引为1，2，3，…(即周期为1)，一个CSI-RS周期包括1个时隙索引。第三信令包括激活周期3和去激活周期2，即在一次波束预测过程中，激活3个CSI-RS资源集周期后自动去激活2个CSI-RS资源集周期，一次波束预测过程的周期为5个CSI-RS资源集周期。
2)若激活周期和去激活周期为非连续周期，则第三信令采用bitmap指示。
在该方式中，第三信令采用bitmap指示，即通过bitmap指示激活/去激活的pattern。示例性的，bitmap中的1表示激活，bitmap中的0表示去激活。
图9示出了一实施例提供的另一种激活周期和去激活周期的示意图。如图9所示，假设周期CSI-RS的发送时隙索引为1，2，3,…(即周期为1)，一个CSI-RS周期包括1个时隙索引。第三信令的bitmap配置为10101，即在一次波束预测过程中，第1个、第3个和第5个CSI-RS资源集周期为激活周期，第2个和第4个CSI-RS资源集周期为去激活周期，一次波束预测过程的周期为5个CSI-RS资源集周期。
3)若CSI-RS为非周期CSI-RS，则第三信令包括配置CSI-RS资源集或CSI-RS资源的重复数量和bitmap中的至少之一。
在该方式中，以图8为例，重复数量为3，UE可以根据此数量的CSI-RS资源集或CSI-RS资源，向基站上报CSI信息；或者，以图9为例，重复数量为5，bitmap配置为10101，UE可以结合重复数量5和bitmap 10101来配置CSI-RS资源集或CSI-RS资源；或者，以图9为例，重复数量也可以理解为3，即描述的是CSI-RS资源集或CSI-RS资源实际重复发送的次数，bitmap为10101。
在第三个示例性实施方式中，对于时域波束预测，本申请定义了一种新的CSI-RS resource set类型：非周期性、周期性、半持久性的CSI-RS resource set的属性定义在资源子集层次。
图10示出了一实施例提供的一种周期性CSI-RS资源的示意图，图11示出了一实施例提供的一种空域波束预测情况下的CSI-RS资源的示意图。结合图10和图11可知，与周期性CSI-RS资源相比，在空域波束预测情况下，可以根据每个时隙内测量的波束，预测该时隙内的空域波束。
对于时域波束预测情况下的CSI-RS资源：将ZP CSI-RS的非周期性、周期性、半持久性的属性定义在资源子集(resource subset)层次。图12示出了一实施例提供的一种时域波束预测情况下的CSI-RS资源子集的示意图。示例性的，以图12所示整个资源子集作为一个整体(即配置周期)；同时，针对图12所示的整个资源子集合，配置参数：重复数量或重复因子、offset和bitmap。其中，offset指示了资源位置，bitmap为0表示该位置未发送参考信号资源，bitmap为1表示发送了参考信号资源。
例如，图12中将5个波束扫描的位置(前3个位置进行波束扫描，后2个位置不进行波束扫描)作为一个整体，repetition number为5，bitmap为11100，而offset参数则被定义在resource set层次，假定5个波束扫描的位置为连续的时隙，第1个CSI-RS resource set中的配置的offset为0，第2个CSI-RS resource set中的配置的offset为1，第3个CSI-RS resource set中的配置的offset为2。
在本申请中，还可以将空域波束预测和时域波束预测相结合，只在一些时刻发送采样波束以降低开销。图13示出了一实施例提供的一种空域波束预测和时域波束预测相结合的CSI-RS资源子集的示意图。在空域波束预测和时域波束预测相结合的情况下，可以采用第二级bitmap指示采样波束的位置(即历史波束测量的位置)。如图13所示，第一级bitmap为11100，对于图13中的第一次波束扫描，第二级bitmap为11111；对于第二次波束扫描，第二级bitmap为10101；对于第三次波束扫描，第二级bitmap为01110。
另外，对于CSI上报，将CSI上报的非周期性、周期性、半持久性属性定 义在resource subset层次，其原理与上述实施例中的描述类似，为了简洁，此处不再赘述。
