为了满足新应用的不断涌现和容量需求的不断增长，未来无线通信网络将充分利用毫米波频段，以提供更大带宽和高数据速率通信。但是，毫米波频段的 传播条件比低频更为严苛，其传输信号的路径损耗大、对阻塞敏感，甚至人体遮挡也会导致信号强度的迅速下降。为此，毫米波信号通常采用大量天线单元形成高定向波束传输，将信号能量集中在一个小角度空间内，以获得较大的天线增益并保证覆盖范围。并且，由于单个波束宽度相对较窄，只能覆盖有限的区域，基站通常利用多个收发波束来覆盖整个小区，同时在数据传输之前需要实现和终端波束的有效对齐。波束管理目的在于建立和维护合适的收发波束对，包括波束扫描、波束测量和上报、波束指示、波束失效检测和恢复四个流程，其对毫米波通信系统至关重要。
在一个典型的波束测量和上报流程中，基站为终端配置多个用于波束测量的参考信号资源，包括信道状态信息参考信号(Channel State Information-Reference Symbol，CSI-RS)资源或同步信号块(Synchronization Signal and物理广播信道(Physical Broadcast Channel，PBCH)block，SSB)，这些参考信号资源分别承载在不同的下行发送波束上。终端对这些参考信号资源进行测量，并将波束测量结果上报给基站。波束测量的上报参数包括终端所选择的一个或多个发送波束对应的参考信号资源索引(比如，SSB资源指示符，(SS/PBCH Block Resource Indicator，SSBRI))，或者，参考信号资源指示符(CSI-RS Resource Indicator，CRI)、物理层参考信号接收功率(Reference Signal Receiving Power，L1-RSRP)或物理层信干噪比(Signal to Interference plus Noise Ratio，L1-SINR)，其中，上报波束个数可由基站根据系统负荷灵活配置。此外，为了体现对多用户面板的支持，对于能够同时接收两个不同参考信号资源(即发送波束)的终端，可以为其配置基于分组的波束上报，这样在每个波束组内，终端可以上报两个不同的参考信号资源，分组个数则由无线资源控制(Radio Resource Control，RRC)参数(比如，nrofReportedRSgroup)配置。
对于L1-RSRP上报，如果基站在CSI报告配置(CSI-ReportConfig)中配置上报资源数为1，则上报的L1-RSRP取值由[-140，_44]dBm范围内的7位有效载荷确定，步长为1dB；如果在CSI-ReportConfig中配置上报资源数大于1，或者基站配置了分组波束上报，则UE应当使用基于差分L1-RSRP的上报。其中，所测量的最大L1-RSRP被量化为[-140，_44]dBm范围内的7位有效载荷，步长为1dB；差分L1-RSRP被量化为[-30，0]dB范围内的4位有效载荷，步长为2dB，并以同一报告实例的最大测量L1-RSRP作为参考RSRP。此外，也支持基于L1-SINR的波束管理机制，将小区间干扰或小区内干扰考虑在内，从而获得更为准确的最优波束信息。L1-SINR的上报采取了与L1-RSRP上报类似的差分 上报机制。
随着人工智能技术的持续发展，无线空口传输与人工智能的融合已经成为未来通信产业发展和标准演进的重要方向。在R18中对人工智能/深度学习技术在空口物理层中的应用进行研究，其中包括评估人工智能/深度学习技术在波束管理中的性能增益和影响。随着未来5G的扩展以及其对人工智能等先进算法的标准支持，现有的波束管理框架将面临严重的压力。举例来说，基站侧进行基于人工智能的模型推理时，需要足够的波束测量结果作为模型输入，这意味着终端可能需要上报大量的波束测量信息，这导致了巨大的信令开销并增加了上行传输的压力。此外，现有的波束上报中未考虑上报波束的时间信息，无法匹配时域波束预测等典型智能空口用例，且上报格式、信令等均存在较大的优化空间。为此，本申请提出了一种信息传输方法，在进行波束上报的同时，有效降低了上报开销，以及提升了上报精度。

在一实施例中，以第一通信节点为终端，第二通信节点为基站为例，对按照参考信号资源索引顺序上报波束测量结果的过程进行说明。示例性地，本实施例中，参考信号资源索引包括：CRI或SSBRI；波束测量结果为RSRP；最大波束测量结果为最大RSRP。
传统的波束上报框架中，终端需要监测和估算所有波束对的质量信息，并选择最优的少数波束信息进行上报，上报参数可以为CRI/SSBRI和RSRP。其中，CRI或SSBRI代表终端选择的CSI-RS资源或SSB资源在资源集合中的索引(即代表了某发送波束)，RSRP表示对应的波束测量结果，也可以理解为对应的波束质量信息。并且，在CSI域的映射顺序中，最大RSRP对应的CRI/SSBRI在第一个位置上报，最大RSRP采用绝对值上报，其余RSRP以最大RSRP作为参考，采用差分上报方式。
在基于人工智能/深度学习的空域波束预测等典型场景下，终端需要上报对所有发送波束的测量信息。为了降低上报开销，终端不需要单独上报CRI/SSBRI，只需要按照CRI/SSBRI的顺序依次上报对应的RSRP，同时采用第一比特信息指示最大RSRP所在的位置，该第一比特信息的取值可以为最大RSRP对应的CRI或其他单独设计的取值。并且，在用于波束测量的参考信号资源集中的CSI-RS或SSB资源数目为K的情况下，则第一比特信息的比特长度为其中，表示向上取整符号。示例性地，图3是本申请实施例提供的一种波束测量信息的上报示意图。如图3所示，假设基站配置了8个CSI-RS资源，分别承载在不同的发送波束上，且终端测量的最大RSRP对应为第三个波束，则终端只需要按照CRI/SSBRI顺序依次上报所有的RSRP，同时上报第一比特信息‘010’，指示基站最大RSRP位于第三个上报波束处。可以理解为，第三个测量波束的RSRP采用绝对值方式上报，其余测量波束的RSRP采用差分方式上报。
或者，终端测量所有发送波束后，对波束测量结果中的最大RSRP采用绝对值方式上报，并将其放在第一个位置上报，其余RSRP以该最大RSRP作为参考，采用差分方式上报。并且，对于最大RSRP对应的波束而言，需要上报其对 应的参考信号资源索引和波束测量结果，其余波束只需要按照CRI的顺序，依次进行差分上报。示例性地，图4是本申请实施例提供的另一种波束测量信息的上报示意图。如图4所示，假设基站配置了8个CSI-RS资源，分别承载在不同的发送波束上，且终端测量的最大RSRP对应为第三个波束，则终端只需要在第一个位置最大RSRP对应的参考信号资源索引，并采用绝对值方式进行上报；其余测量波束的波束测量结果按照CRI的顺序，依次进行差分方式上报对应的波束测量结果，而不需要上报参考信号资源索引。
在一实施例中，为了提升上报精度，设置多个参考RSRP，其中，参考RSRP均采用绝对值上报方式，其余RSRP以同一波束组内的最大RSRP作为参考，采取差分上报方式。首先，由基站在下行信令中配置参考RSRP的个数N，或配置波束组大小M；当N或M不被配置时，表示参考RSRP个数或波束组大小采用默认值。类似的，终端在测量所有发送波束所承载的参考信号资源后，将波束测量结果分为N个波束组，或者，将波束测量结果分为大小为M的多个波束组。预设分组方式为终端按照CRI/SSBRI的顺序，依次将波束测量结果分为多个波束组。并且，终端对每个波束组内的最大RSRP采用绝对值方式上报，并使用额外的第二比特信息指示每个波束组中最大RSRP所在上报位置，此额外的第二比特信息的取值可以为参考RSRP对应的CRI或其他单独设计的取值；每个波束组内的其余RSRP以该组内的最大RSRP作为参考，采用差分上报方式。每个波束组对应的额外比特长度为其中K表示用于波束测量的参考信号资源集中的CSI-RS或SSB资源数目，表示向上取整符号。
示例性地，图5是本申请实施例提供的又一种波束测量信息的上报示意图。如图5所示，假设基站配置8个参考信号资源分别承载在不同发送波束传输，且基站配置参考RSRP个数为N＝2或配置波束组大小为M＝4，即表示将发送波束分为大小为4的两个波束组，则上报格式示意图如图5所示。其中，额外的第二比特信息‘10’指示第一个波束组中最大RSRP位于第三个波束，额外的第二比特信息‘01’指示第二个波束组中最大RSRP位于第二个波束。
在一实施例中，以第一通信节点为终端，第二通信节点为基站为例，对配置 多个参考RSRP(即最大RSRP)，以及上报参考信号资源索引的过程进行说明。示例性地，本实施例中，参考信号资源索引包括：CRI或SSBRI；波束测量结果为RSRP；最大波束测量结果为最大RSRP。
在基于人工智能/深度学习的空域波束预测等典型场景下，终端需要上报对所有发送波束的测量信息。为了提升上报精度，设置多个参考RSRP(即最大RSRP)，其中，参考RSRP均采取绝对值方式进行上报，其余RSRP以同一波束组内的最大RSRP作为参考，并采取差分方式进行上报。
由基站在下行信令中配置参考RSRP的个数N，或配置波束组大小为M，在N或M不被配置的情况下，表示参考RSRP个数或波束组大小均采用默认值。终端在测量所有发送波束所承载的参考信号资源后，将波束测量结果分为N个波束组，或者将波束测量结果分为大小为M的多个波束组。预设分组方式可以为终端将波束测量结果RSRP从大到小排序，并依次分为多个波束组；或者终端根据接收波束的不同进行分组，同一个波束组内的多个RSRP表示终端采用同一个接收波束得到的测量结果。此外，终端对每个波束组内的最大RSRP采用绝对值方式上报，并将其放在每个波束组的第一个位置上报，每个波束组内的其余RSRP以该组内的最大RSRP作为参考，采用差分方式进行上报。示例性地，图6是本申请实施例提供的再一种波束测量信息的上报示意图。如图6所示，假设基站配置8个参考信号资源，并分别承载在不同发送波束传输，且基站配置参考RSRP个数为N＝2或配置波束组大小为M＝4，即表示终端将发送波束分为大小为4的两个波束组，并且，最大RSRP采用绝对值方式上报，以及其它RSRP采用差分方式上报。
在一实施例中，为了降低上报开销，最后一个波束组内，只需要上报最大RSRP及其对应的参考信号资源索引，其余波束测量结果只需要按照剩余CRI/SSBRI的顺序，依次上报其对应的差分RSRP。示例性地，图7是本申请实施例提供的再一种波束测量信息的上报示意图。如图7所示，第一个波束组内，上报每个参考信号资源对应的波束测量结果，以及参考信号资源索引，并且，最大RSRP采用绝对值方式上报，以及其它RSRP采用差分方式上报；第二个波束组内，上报最大RSRP和对应的参考资源索引，并且，最大RSRP采用绝对值方式上报，以及其它RSRP采用差分方式上报。
在一实施例中，以第一通信节点为终端，第二通信节点为基站为例，对由UE灵活选择分组大小，并上报参考信号资源索引的过程进行说明。示例性地，本实施例中，参考信号资源索引包括：CRI或SSBRI；波束测量结果为RSRP；最大 波束测量结果为最大RSRP。
在基于人工智能/深度学习的空域波束预测等典型场景下，终端需要上报对所有发送波束的测量信息。为了提升上报精度，设置多个参考RSRP(即最大RSRP)，其中，参考RSRP均采取绝对值方式进行上报，其余RSRP以同一波束组内的最大RSRP作为参考，采取差分方式进行上报。
在上述实施例中，采用的是固定或预定义的分组方式，即按照一定规则将波束测量结果等分为多个波束组，并分别上报。在实施例中，提供一种更为灵活的分组和上报方式。首先，由基站在下行信令中配置参考RSRP的个数N，或者由终端自主决定参考RSRP的个数N。在N不被配置的情况下，表示参考RSRP个数为1或采用默认值。终端在测量所有发送波束所承载的参考信号资源后，选择其中N个波束测量结果作为参考RSRP，采用绝对值上报方式；其余波束以这N个参考RSRP中的其中一个RSRP作为参考，采用差分上报方式。并且，差分方式上报的每个波束均需要上报对应的额外的第三比特信息，其中，第三比特信息用于指示其所选择的参考RSRP位置，额外的第三比特信息的长度为其中表示向上取整符号。示例性地，图8是本申请实施例提供的再一种波束测量信息的上报示意图。如图8所示，基站配置8个参考信号资源，并分别承载在不同发送波束传输，且基站配置参考RSRP个数为N＝2，则上报格式如图8所示。其中，额外的第三比特信息为‘0’指示所选择的参考RSRP位于第一个位置(即CRI3)，额外的第三比特信息为‘1’指示所选择的参考RSRP位于第二个位置(即CRI1)。
在一实施例中，为了降低上报开销，对参考RSRP对应的波束而言，需要上报其RSRP及其对应的参考信号资源索引，其余波束测量结果只需要按照剩余CRI/SSBRI的顺序，依次上报其对应的差分RSRP以及所选择的参考RSRP位置。示例性地，图9是本申请实施例提供的再一种波束测量信息的上报示意图。如图9所示，将最大RSRP对应的参考信号资源索引(即CRI3和CRI1)进行上报，而其它的RSRP不上报参考信号资源索引，并采用绝对值方式上报最大RSRP，以及其它RSRP采用差分方式上报，并将其它RSRP所选择的参考RSRP的位置进行上报。如图9所示，额外的第三比特信息为‘0’指示所选择的参考RSRP位于第一个位置(即CRI3)，额外的第三比特信息为‘1’指示所选择的参考RSRP位于第二个位置(即CRI1)。
在一实施例中，以第一通信节点为终端，第二通信节点为基站为例，对配置一个参考RSRP(即最大RSRP)，以及上报参考信号资源索引、RSRP和时间信 息的过程进行说明。示例性地，本实施例中，参考信号资源索引包括：CRI或SSBRI；波束测量结果为RSRP；最大波束测量结果为最大RSRP。
在基于人工智能/深度学习的时域波束预测或空时域波束预测等典型场景下，终端需要上报连续多个时刻内对发送波束的测量信息，也即不同时刻的同一个波束会被多次测量，并在同一个上报实例中被上报。为了实现对基站的有效指示，终端的波束测量信息包括CRI/SSBRI、RSRP和时间信息，其中CRI或SSBRI代表终端选择的CSI-RS资源或SSB资源在资源集合中的索引(即代表了某发送波束)，RSRP代表了对应的波束质量信息，时间信息代表对应波束的测量时间。时间信息可以为对应波束所承载的参考信号资源所在的符号、时隙、子帧、帧等。时间信息的上报方式可以分为以下三种形式：
图10是本申请实施例提供的再一种波束测量信息的上报示意图。如图10所示，在每个时刻内，每个测量波束均需要携带时间信息。
图11是本申请实施例提供的再一种波束测量信息的上报示意图。如图11所示，同一个时刻的多个或所有测量波束被作为一个波束组，只有波束组需要携带时间信息。
图12是本申请实施例提供的再一种波束测量信息的上报示意图。如图12所示，所有的波束测量结果先按照CRI/SSBRI顺序进行排序，然后依次按时间信息先后上报，此上报顺序即隐含了时间信息。
在一实施例中，为了指示基站最大RSRP所在位置，终端需要上报额外的第四比特信息，其中，第四比特信息用于指示终端所选择的最大RSRP所在时刻和所处上报位置。假设在一个上报实例中，终端上报了过去T个时刻的波束测量结果，则额外的第四比特信息的长度为其中表示向上取整符号。示例性地，图13是本申请实施例提供的再一种波束测量信息的上报示意图。如图13所示，如果终端上报过去4个时刻的波束测量结果，每个时刻上报最优的4个波束，为了实现对基站的指示，终端需要额外上报第四比特信息‘01’，通知基站第二个时刻的第一个位置的波束测量结果采取绝对值上报方式，其他所有时刻的波束测量结果采取差分上报方式。
在一实施例中，如果每个时刻终端上报波束对应的CRI/SSBRI都一样，则终端在同一个上报实例中上报多个时刻的波束测量结果时，对应的CRI/SSBRI只需要上报一次，并上报额外的第四比特信息，其中，第四比特信息用于指示最大RSRP所在时刻和所处上报位置。并且，不同时刻对应的波束测量结果的上报顺序必须保持一致，以避免基站的错误解码。假设在一个上报实例中，终端上报 了过去T个时刻的波束测量结果，则额外比特的长度为其中表示向上取整符号。示例性地，图14是本申请实施例提供的再一种波束测量信息的上报示意图。如图14所示，如果终端上报过去4个时刻的波束测量结果，每个时刻上报相同的4个波束，为了实现对基站的指示，终端需要额外上报比特‘01’，通知基站第二个时刻的第一个位置的波束测量结果采取绝对值上报方式，其他所有时刻的波束测量结果采取差分上报方式。
在一实施例中，如果每个时刻终端上报波束对应的CRI/SSBRI都一样，且为基站所已知，则终端在同一个上报实例中上报多个时刻的波束测量结果时，只需要按CRI/SSBRI的顺序依次上报各个时刻的波束测量结果，并上报额外的第四比特信息，其中，第四比特信息用于指示最大RSRP所在位置。额外的第四比特信息由两部分组成，第一部分的额外比特用于指示最大RSRP所在时间；第二部分的额外比特用于指示最大RSRP对应的参考信号资源索引，此部分额外比特取值可以为参考RSRP对应的CRI或其他单独设计的取值。假设在一个上报实例中，终端上报了过去T个时刻的波束测量结果，每个时刻上报的波束数目为K，则额外的第四比特信息的长度为或其中比特用于指示最大RSRP对应的时刻，比特用于指示最大RSRP对应的参考信号资源索引，表示向上取整符号。示例性地，图15是本申请实施例提供的再一种波束测量信息的上报示意图。如图15所示，如果终端上报过去4个时刻的波束测量结果，每个时刻上报相同的4个波束(CRI1～CRI4)，为了实现对基站的指示，终端需要按CRI顺序上报所有的测量波束。并且，终端额外上报时间指示比特‘10’和资源索引指示比特‘01’，通知基站第三个时刻的第二个位置(即CRI2)的波束测量结果采取绝对值上报方式，其他所有时刻的波束测量结果采取差分上报方式。
在一实施例中，以第一通信节点为终端，第二通信节点为基站为例，对配置多个参考RSRP(即最大RSRP)，以及上报参考信号资源索引、RSRP和时间信息的过程进行说明。示例性地，本实施例中，参考信号资源索引包括：CRI或SSBRI；波束测量结果为RSRP；最大波束测量结果为最大RSRP。
在基于人工智能/深度学习的时域波束预测或空时域波束预测等典型场景下，终端需要上报连续多个时刻内对发送波束的测量信息，也即不同时刻的同一个波束会被多次测量，并在同一个上报实例中被上报。为了实现对基站的有效指示并提升上报精度，在实施例中，终端选择多个波束测量结果进行绝对值上报，其余测量结果进行差分上报。
如果每个时刻上报的波束都一样，则终端只需要上报一次参考信号资源索引，且每个时刻上报的参考信号资源索引保持一致。此外，每个时刻的多个波束测量结果中，均选择一个功率最大的RSRP作为参考RSRP，采取绝对值上报方式，其余RSRP以同一时刻的最大RSRP为参考，进行差分上报。由于每个时刻的波束上报顺序一样，因此需要上报额外的第五比特信息，其中，第五比特信息用于指示最大RSRP所在上报位置。此额外的第五比特信息的取值可以为最大RSRP对应的CRI或其他单独设计的取值，并且，当用于波束测量的参考信号资源集中的CSI-RS或SSB资源数目为K时，则额外的第五比特信息的长度为其中表示向上取整符号。此外，如果终端上报的所有波束对应的参考信号资源索引都是基站侧已知的，则终端只需要按照CRI/SSBRI的顺序依次上报所有波束，而不需要单独上报每个波束对应的CRI/SSBRI。
示例性地，图16是本申请实施例提供的再一种波束测量信息的上报示意图。如图16所示，如果终端上报过去4个时刻的波束测量结果，每个时刻上报相同的4个波束，为了实现对基站的指示，终端需要额外上报比特‘01’、‘10’、‘00’、‘11’，通知基站所上报的4个时刻中，各个时刻最大RSRP所在位置分别位于第二个波束、第三个波束、第一个波束和第四个波束，这些波束测量结果采取绝对值上报方式，其他波束测量结果均采取差分上报方式。在另一种情况中，针对各个时刻对同一个波束测量得到的多个波束测量结果，均选择一个功率最大的RSRP作为参考RSRP，采取绝对值上报方式，该波束其他时刻测量得到的RSRP以同一波束的最大测量RSRP为参考，进行差分上报。如果每个时刻终端上报波束对应的CRI/SSBRI都一样，则终端在同一个上报实例中上报多个时刻的波束测量结果时，对应的CRI/SSBRI只需要上报一次。并且，如果终端上报的所有波束对应的参考信号资源索引都是基站侧已知的，则终端只需要按照CRI/SSBRI的顺序依次上报所有波束，而不需要单独上报每个波束对应的CRI/SSBRI。此外，终端上报的每个波束均需要携带额外的第六比特信息以指示最大RSRP的时间信息。假设在一个上报实例中，终端上报了过去T个时刻的波束测量结果，则额外的第六比特信息的长度为其中表示向上取整符号。
示例性地，图17是本申请实施例提供的再一种波束测量信息的上报示意图。如图17所示，如果终端上报过去4个时刻对索引为CRI1和CRI3的波束测量结果，为了实现对基站的指示，终端上报的每个波束均需要携带额外的第六比特信息以指示最大RSRP的时间信息。针对波束CRI1，携带额外的第六比特信息为‘10’指示基站最大RSRP位于第三个时刻，该波束其他时刻的测量结果以第 三个时刻的RSRP为参考，进行差分上报。针对波束CRI3，携带额外的第六比特信息为‘01’指示基站最大RSRP位于第二个时刻，该波束其他时刻的测量结果以第三个时刻的RSRP为参考，进行差分上报。
在一实施例中，在现有协议中，配置了信道状态信息上报的上报参数、量化比特长度和量化步长之间的关系。举例而言，根据现有协议所提供的测量上报映射表，所测量的最大L1-RSRP被量化为[-140，_44]dBm范围内的7位有效载荷，步长为1dB；差分L1-RSRP被量化为[-30，0]dB范围内的4位有效载荷，步长为2dB，并以同一报告实例的最大测量L1-RSRP作为参考RSRP。为了实现更为精确的上报效果且体现对人工智能/深度学习算法的支持，可以重配置一张新的测量上报映射表(即上述实施例中的目标测量上报映射表)，相比于传统的测量上报映射表，新的测量上报映射表定义了更长的量化比特和更短的量化步长，从而提升上报精度。终端在接入小区或进入RRC连接态后，需要上报对不同测量上报映射表的支持能力。根据终端的能力上报结果，基站对终端上报时所采用的测量上报映射表进行指示，包括媒体接入控制-控制单元(Media Access Control control element，MAC CE)或下行控制信息(Downlink Control Information，DCI)信令动态指示或其他隐含指示方法，或者终端自主选择上报时所采用的测量上报映射表，并在上行传输中通知基站所选择的测量上报映射表。
