下面对本申请所涉及到的一些通信术语或名词进行解释说明。
1、波束(beam)
波束在新空口(New Radio，NR)协议中的体现可以称为空域滤波器(spatial domainfilter)、空间滤波器(spatial filter)或空间参数(spatial parameter)。用于发送信号的波束可以称为发送波束(transmission beam，Tx beam)、空域发送滤波器(spatial domain transmission filter)或空间发射参数(spatial transmissionparameter)；用于接收信号的波束可以称为接收波束(reception beam，Rx beam)、空域接收滤波器(spatial domain receive filter)或空间接收参数(spatial RXparameter)。
发送波束可以是指信号经天线发射出去后在空间不同方向上形成的信号强度的分布，接收波束可以是指从天线上接收到的无线信号在空间不同方向上的信号强度分布。
应理解，上文列举的NR协议中对于波束的体现仅为示例，不应对本申请构成任何限定。本申请并不排除在未来的协议中定义其他的术语来表示相同或相似的含义的可能。
此外，波束可以是宽波束，或者窄波束，或者其他类型波束。形成波束的技术可以是波束赋形技术或者其他技术。波束赋形技术具体可以为数字波束赋形技术、模拟波束赋形技术或者混合数字/模拟波束赋形技术等。不同的波束可以认为是不同的资源。通过不同的波束可以发送相同的信息或者不同的信息。
可选地，将具有相同或者类似的通信特征的多个波束视为是一个波束。一个波束内可以包括一个或多个天线端口，用于传输数据信道、控制信道和探测信号等。形成一个波束的一个或多个天线端口也可以看作是一个天线端口集。
在本申请实施例中，若未做出特别说明，波束是指网络设备的发送波束。在波束测量中，网络设备的每一个波束对应一个资源，因此可以以资源的索引来唯一标识该资源对应的波束。
2、信道信息
信道信息可以包括以下一种或多种：波束质量、信道质量指示(channel quality indicator，CQI)、预编码矩阵指示符(precoding matrix indicator，PMI)、层指示(layer indicator，LI)、秩指示(rank indicator，RI)、时延扩展(delay spread)、多普勒扩展(doppler spread)、多普勒频移(doppler shift)、平均时延(average delay)、平均增益、空间接收参数(spatial Rx parameters)。
其中，波束质量可以为以下一种：参考信号接收功率(reference signal receiving power，RSRP)、参考信号接收质量(reference signal receiving quality，RSRQ)或信号与干扰加噪声比(signal to interference plus noise ratio，SINR)。
空间接收参数可以包括以下的一种或多种：到达角(angle of arrival，AOA)、平均AOA、AOA扩展、离开角(angle of departure，AOD)、平均离开角AOD、AOD扩展、接收天线空间相关性参数、发送天线空间相关性参数。
可选的，本申请实施例中需要采用绝对值量化上报的对象不限于信道信息中波束质量，还可以为信道信息中除波束质量之外的其他信息，本申请实施例中需要采用差分量化上报的对象不限于波束质量，还可以为信道信息中除波束质量之外的其他信息，在此不做限制。
3、波束质量信息
波束质量信息是对波束质量进行量化确定的。如，针对参考信号接收功率(reference signal receiving power，RSRP)，如果终端设备只需上报一个参考信号的RSRP，或者对于终端设备上报的多个参考信号的RSRP中最大的一个，波束质量信息是对RSRP进行量化确定的。对于终端设备上报的多个参考信号的RSRP中除最大RSRP之外的其他RSRP，波束质量信息是对差分RSRP进行量化确定的，其中，差分RSRP例如可以为最大RSRP与除最大RSRP之外的RSRP之间的差值。
4、绝对值量化和差分量化
绝对值量化，即量化测量值。例如，根据3GPP标准协议TS 38.133 v16.1.0表格10.1.6.1-1，如果RSRP测量值为-100dBm，其量化结果对应的波束质量信息为RSRP_57，若根据3GPP标准协议TS 38.214 v16.2.0的要求使用7个比特进行上报RSRP，即为0111001。
差分量化，即量化两个测量值之间的差值。例如，如果两个波束质量分别为-105.5dBm与-100dBm，以其中最大值-100dBm为参考，-105.5dBm对应的差分RSRP为-5.5dB，即-105.5dBm与-100dBm之间的差值，根据3GPP标准协议TS 38.133 v16.1.0表格10.1.6.1-2，终端设备对-5.5dB的差分RSRP进行量化后其量化结果对应的波束质量信息为DIFFRSRP_2。若根据3GPP标准协议TS 38.214 v16.2.0的要求使用4个比特进行上报差分RSRP，即为0010。
上述内容简要阐述了本申请实施例所涉及的部分名词(或术语)的含义，为更好地理解本申请实施例的提供的信道信息上报方法，下面将对本申请实施例提供的信道信息上报方法的系统架构和/或应用场景进行说明。可理解的，本申请实施例描述的场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定。
为了便于理解本申请，在此介绍本申请实施例涉及的相关技术知识。
一般来说，接入网设备可以向终端设备发送配置信息，该配置信息包括资源配置信息和上报配置信息。其中，资源配置信息包括一个或多个资源集合，每一个资源集合包括一个或多个下行信号的资源，每个下行信号的资源对应一个波束。下行信号包括：信道状态信息参考信号(channel state informationreference signal，CSI-RS)、小区专用参考信号(cell specific  reference signal，CS-RS)、UE专用参考信号(user equipment specific reference signal，US-RS)、解调参考信号(demodulation reference signal，DMRS)、以及同步信号/物理广播信道块(synchronization signal/physical broadcast channel block，SS/PBCH block)。其中，SS/PBCH block可以简称为同步信号块(synchronization signal block，SSB)。上报配置信息包括以下至少一种：终端设备需要上报下行信号的资源标识、终端设备需要上报的波束质量的数目等。另外，上报配置信息还包括资源配置信息的标识，以指示终端设备基于哪一个资源配置信息所配置的资源来测量参考信号。
进一步的，接入网设备可以通过一个或多个发送波束发送一个或多个参考信号给终端设备。终端设备通过一个或多个接收波束接收一个或多个参考信号。终端设备接收到的一个或多个参考信号进行测量，得到一个或多个波束质量。然后，终端设备可以上报波束质量。在一种可能的方式中，终端设备可以根据配置信息进行上报，比如，根据终端设备需要上报的波束质量的数目上报波束质量。最后，接入网设备可以根据终端设备上报的波束质量和调度策略等选择适合数据传输的波束并指示给该终端设备。
需要说明的是，在一种实现方式中，终端设备可以按照接入网设备的配置上报测量得到的所有波束质量中的全部或者部分波束质量给接入网设备，例如，终端设备测量得到3个波束质量，则终端设备上报这2个波束质量给接入网设备。在另一种实现方式中，终端设备可以上报测量得到的波束质量中大于门限值的波束质量给接入网设备，例如，终端设备测量得到3个波束质量，其中，2个波束质量大于门限值，则终端设备上报这2个波束质量给接入网设备。
其次，当上报的波束质量的数量大于1个时，终端设备可以将质量最好的波束质量作为参考值，并采用差分量化对除参考值之外的其余波束质量进行量化后上报。
进一步的，终端设备在上报量化后的波束质量时，可以涉及到不同的比特位宽。示例性的，参见表1，在表1中，RSRP(质量最好的RSRP)对应的比特位宽(bitwidth)为7，差分RSRP(differential RSRP)对应的比特位宽为4，即需要差分上报的RSRP对应的比特位宽为4。可以理解的，比特位宽的具体数值，在本申请中不做限制。
表1：上报波束质量时涉及到的比特位宽
字段(field) 比特位宽
RSRP 7
differential RSRP 4
可以理解的，针对质量最好的波束质量，终端设备采用绝对值量化，以使用7个比特进行上报。如质量最好的RSRP为-100dBm，结合表3，可以确定-100dBm对应的波束质量信息为RSRP_57，RSRP_57以二进制比特表示为0111001。另外，针对质量最好的波束质量，其对应的量化步长为1dB。针对除质量最好的波束质量之外的其他波束质量，终端设备可以根据其他波束质量中每个波束质量与质量最好的波束质量之间的差值进行量化，即对其他波束质量中每个波束质量采用差分量化，以使用4个比特进行上报。如，质量最好的RSRP1为-100dBm，RSRP2为-105.5dBm，RSRP3为-110dBm。那么，RSRP2与RSRP1之间的差值为-5.5dB，RSRP3与RSRP1之间的差值为-11dB。进一步的，参见表2，在表2中，DIFFRSRP_1对应的量化范围为：-2≥ΔRSRP＞-4；DIFFRSRP_2对应的量化范围为：-4≥ΔRSRP＞-6；DIFFRSRP_3对应的量化范围为：-6≥ΔRSRP＞-8；DIFFRSRP_4对应的量化范围为：-8≥ΔRSRP＞-10；DIFFRSRP_5对应的量化范围为：-10≥ΔRSRP＞-12。即，量化步长均为2dB。结合表 2，可以看出，-5.5dB落入的量化范围为-4≥ΔRSRP＞-6，即RSRP2对应的波束质量信息为DIFFRSRP_2，DIFFRSRP_2以二进制比特表示为0010；-11dB落入的量化范围为-10≥ΔRSRP＞-12，即RSRP2对应的波束质量信息为DIFFRSRP_5，DIFFRSRP_5以二进制比特表示为0101。

Figure PCTCN2020116342-appb-000001
综上，可以看出，波束质量的量化过程与量化步长有关。如，质量最好的波束质量为-80dBm，其他波束质量中某个波束质量为-84.1dBm，其他波束质量中另一个波束质量为-85.9dBm。那么，-84.1dBm与-80dBm之间的差值为-4.1dBm，-84.1dBm与-85.9dBm之间的差值为-5.9dB，结合表2，可以看出，-4.1dB和-5.9dB落入的量化范围均为-4≥ΔRSRP＞-6，即终端设备向接入网设备上报的均为DIFFRSRP_2。同时，接入网设备在根据量化步长和质量最好的波束质量对DIFFRSRP_2解析时，由于DIFFRSRP_2对应的-4≥ΔRSRP＞-6，针对-84.1dBm和-85.9dBm，接入网设备可以确定其对应的均为-84dBm至-86dBm。而-86dBm和-84.1dBm之间相差1.9dB，-84dBm和-85.9dBm相差1.9dB。可以看出，针对一个波束质量，终端设备在量化时或接入网设备在解析时最大可以接近2dB的误差。因此，如何降低量化误差是个亟待解决的问题。
