下面结合附图对本申请所提供的信道测量方法及其装置进行详细地介绍。
图2为本申请一实施例的信道测量方法的流程示意图，该方法应用于终端设备，如图2所示，该方法包括：
S21，获取时频资源中多个子带中的不可用子带。
如图3所示，信号在太赫兹频段的传播损耗比较严重，导致不同距离的用户具有不同的可用带宽。在本实施例中，终端设备对时频资源中的信号进行测量，进而获取通信中的不可用带宽。
本实施例中定义了时频频域的资源单位子带，比如，1个子带包含M个资源块(resource block，RB)，1个资源块包含N个正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)子载波。
在一些实现中，设置有参考信号，通过对接收的参考信号进行测量，获取多个子带中的不可用子带。
可选地，可以在频域不同位置的多个子带上接收参考信号，也可以在不同时间接收子带上的参考信号。
S22，向网络设备发送指示信息，其中，指示信息用于向网络设备上报不可用子带。
可选地，终端设备基于不可用子带生成指示信息，或者，基于可用子带生成指示信息，并将指示信息发送给网络设备。在一些实现中，指示信息可以显示指示，例如，可以直接上报不可用子带的起始子带序号和不可用子带的子带数目。在另一些实现中，指示信息也可以隐式指示，例如，可以上报不可用子带的表征信息，如不可用子带的资源指示值。
本申请实施例提供一种信道测量方法，通过终端设备在配置的时频资源上进行测量，获取通信中的不可用带宽，为基站调度提供准确的信道质量信息。
图4为本申请一实施例的信道测量方法的流程示意图，该方法应用于终端设备，如图4所示，该方法包括：
S41，在多个子带上接收参考信号。
可选地，网络设备在多个子带上同时向终端设备发送参考信号，或者，网络设备在多个子带上分时向终端设备发送参考信号。根据参考信号的发送方式，可选地，终端设备可以在多个子带上同时接收各自传输的参考信号，或者，在多个子带上分时接收各自传输的参考信号。
其中，参考信号可以是小区参考信号(Cell Reference Signal，CRS)、信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS)、解调参考信号(Demodulation Reference Signal，DRS)、上行探测参考信号(Sounding Reference Signal，SRS)、解调参考信号(DemodulationReference Signal，DMRS)。
S42，对多个子带上传输的参考信号进行测量，获取不可用子带。
对接收的参考信号进行测量，获取参考信号的测量结果，该测量结果可以反应子带的质量，本公开中，可以根据参考信号的测量结果，从多个子带中确定出不可用子带。可选地，也可以根据参考信号的测量结果，从多个子带中确定出可用子带。其中不可用子带的质量较差，可用子带的质量较好。
例如，可以有设定的阈值，当参考信号的测量结果低于设定阈值，则传输该参考信号的子带为不可用子带。
S43，向网络设备发送指示信息，其中，指示信息用于向网络设备上报不可用子带。
关于步骤S43的具体实现可以参见本公开各实施例中相关介绍，此处不再赘述。
本申请实施例提供一种信道测量方法，通过对参考信号进行测量，获取到通信中的不可用带宽。
图5为本申请一实施例的信道测量方法的流程示意图，该方法应用于终端设备，如图5所示，该方法包括：
S51，在通过第一信令配置或协议约定的时频资源上对参考信号进行接收。
网络设备通过第一信令把测量参考信号的时频资源指示给终端设备，并在配置的时频资源上对参考信号进行传输。
S52，通过第二信令配置或协议约定目标信号质量。
网络设备通过第二信令把目标信号质量配置给终端设备，终端设备将配置的目标信号质量与接收的参考信号质量进行对比。
其中，目标信号质量为终端设备所能接受的最低信号质量，为了进行对比，目标信号质量包括信号的各项测量值。
S53，通过第三信令配置或协议约定目标测量量。
网络设备通过第三信令把目标测量量指示给终端设备，目标测量量包括以下至少一个：参考信号接收功率RSRP、参考信号接收质量RSRQ、信噪比和干扰比SINR、接收信号强度指示RSSI。
参考信号接收功率(Reference Signal Receiving Power，RSRP)是长期演进(Long Term Evolution，LTE)网络中可以代表无线信号强度的关键参数以及物理层测量需求之一，是考虑的测量频率带宽上承载参考信号的所有资源粒子上接收到的信号功率的平均值。
接收信号强度指示(Received Signal Strength Indication，RSSI)是无线发送层的可选部分，用来判定链接质量，以及是否增大广播发送强度。
参考信号接收质量(Reference Signal Receiving Quality，RSRQ)被定义为N*RSRP/(发送载波RSSI)之比，其中N是发送载波RSSI测量带宽的资源块RB个数。RSRQ实现了一种有效的方式报告信号强度和干扰相结合的效果。
信噪比和干扰比(Signal to Interference plus Noise Ratio，SINR)是指接收到的有用信号的强度与接收到的干扰信号的强度的比值，可以简单的理解为信噪比。
S54，对多个子带上传输的参考信号进行测量，获取不可用子带。
根据第三信令配置的目标测量量对参考信号进行测量，例如，当目标测量量为RSRP时，对参考信号的RSRP进行测量；当目标测量量为RSRQ和SINR时，对参考信号的RSRQ和SINR进行测量。
获取参考信号在多个子带上的目标测量量，确定目标测量值小于目标信号质量的目标子带，其中，目标子带为不可用子带。

因为不可用子带一般为连续的多个子带，所以可以获取不可用子带的第一起始子带序号和不可用子带的第一子带数目。例如，当不可用子带为子带序号为8、9、10的子带，则第一起始子带序号为8，第一子带数目为3。
当不可用子带为不连续的多个子带，则可以获取多组第一子带起始序号和第一子带数目。例如，当不可用子带序号为6、7、8、10、11，此时第一组第一子带起始序号为6，第一子带数目为3，第二组第一子带起始序号为10，第一子带数目为2。
