通常情况下，在载波带宽为大带宽的通信***中，终端设备的带宽能力可能小于载波带宽。例如，在5G移动通信***的新空口(new radio，NR)技术中，载波带宽最大可能为400MHz，终端设备的带宽能力可能为20MHz、50MHz或100MHz等。在5G***中，网络设备通过为终端设备配置载波带宽中的部分载波带宽(以下称之为“载波带宽部分”)，并将该载波带宽部分中的部分或全部资源分配给终端设备，以供网络设备与终端设备间的通信；其中，该载波带宽部分的带宽小于或等于终端设备的带宽能力。
在部分应用场景下(例如多参数场景、带宽回退场景等)，网络设备确定终端设备需要进行载波带宽部分的切换。由于不同带宽大小的载波带宽部分对应的频率分集增益不同，为了保证上行信息能正确接收，终端设备在不同带宽大小的载波带宽部分上发送信息时所采用的发射功率应该也不同。
在上述方法中，网络设备采用小区或载波特定的配置方式(即不同的小区或载波独立配置的方式)为终端设备配置功率控制参数，即终端设备在小区或载波内各频率资源上均使用相同的功率控制参数。
在配置有载波带宽部分的场景中，不同载波带宽部分的配置可能不同，在该场景中如何进行功率控制是一个值得被研究的问题，以保证上行信息的正确接收。
本申请实施例提供的功率控制方法及装置，网络设备通过采用载波带宽部分特定的配置方式(即不同的载波带宽部分独立配置的方式)为终端设备配置功率控制参数，实现了网络设备根据载波带宽部分的不同为终端设备配置不同的功率控制参数，以便终端设备在不同载波带宽部分上可以采用不同的发射功率发送信息，从而保证了在载波带宽部分切换时的上行信号质量(或上行覆盖)。
本申请实施例中涉及的第一载波带宽部分和第二载波带宽部分可以位于同一载波。可选地，第一载波带宽部分和第二载波带宽部分也可以位于不同载波，例如对于LTE和NR共存场景，第一载波带宽部分位于NR专用上行载波(NR dedicated uplink)载波或频率，第二载波带宽部分位于增补上行(supplementary uplink，SUL)载波或频率。专用上行载波和增补上行载波可以属于同一个小区。

需要说明的是，终端设备根据任一载波带宽部分对应的功率控制参数确定在该载波带宽部分进行数据传输对应的发射功率的方式，可以参见上述“终端设备根据第一功率控制参数确定在第一载波带宽部分进行数据传输对应的第一发射功率”的方式，此处不再赘述。
步骤S203、终端在第一载波带宽部分上根据第一发射功率发送第一上行信息，和/或，在第二载波带宽部分上根据第二发射功率发送第二上行信息。
其中，第一发射功率是根据第一功率控制参数确定的，第一功率控制参数是根据功率控制参数指示信息确定的；第二发射功率是根据第二功率控制参数确定的，第二功率控制参数是根据功率控制参数指示信息确定的。
本步骤中，终端设备在根据功率控制参数指示信息(用于指示网络设备为终端设备所分配的至少一个载波带宽部分分别对应的功率控制参数)确定出该至少一个载波带宽部分对应的功率控制参数，并分别根据该至少一个载波带宽部分中每个载波带宽部分对应的功率控制参数确定在每个载波带宽部分进行数据传输对应的发射功率后，分别在每个载波带宽部分上根据对应的发射功率发送上行信息。
例如，若功率控制参数指示信息用于指示载波带宽部分A对应的功率控制参数A，则终端设备在根据功率控制参数指示信息确定载波带宽部分A对应的功率控制参数A，并根据功率控制参数A确定在载波带宽部分A进行数据传输对应的发射功率后，在载 波带宽部分A上根据该发射功率发送上行信息；其中，如载波带宽部分A可以为本申请实施例中涉及的第一载波带宽部分，对应的功率控制参数A可以为第一功率控制参数以及对应的发射功率可以为第一发射功率；载波带宽部分A可以为本申请实施例中涉及的第二载波带宽部分，对应的功率控制参数B可以为第二功率控制参数以及对应的发射功率可以为第二发射功率。
又例如，若功率控制参数指示信息用于指示第一载波带宽部分对应的第一功率控制参数和第二载波带宽部分对应的第二功率控制参数，则终端设备在根据功率控制参数指示信息确定第一载波带宽部分对应的第一功率控制参数和第二载波带宽部分对应的第二功率控制参数，并根据第一功率控制参数确定在第一载波带宽部分进行数据传输对应的第一发射功率，以及根据第二功率控制参数确定在第二载波带宽部分进行数据传输对应的第二发射功率后，分别在第一载波带宽部分上根据第一发射功率发送第一上行信息，以及在第二载波带宽部分上根据第二发射功率发送第二上行信息。
当然，功率控制参数指示信息还可以用于指示其它数量个载波带宽部分对应的功率控制参数，对应地，终端设备在根据功率控制参数指示信息确定各载波带宽部分对应的功率控制参数，并确定在各载波带宽部分进行数据传输对应的发射功率后，分别在每个载波带宽部分上根据对应的发射功率发送上行信息。
步骤S204、网络设备在第一载波带宽部分接收第一上行信息，和/或，在第二载波带宽部分接收第二上行信息。
若功率控制参数指示信息用于指示网络设备为终端设备所分配的至少一个载波带宽部分分别对应的功率控制参数，则网络设备在各载波带宽部分分别接收终端设备发送的上行信息。
例如，若功率控制参数指示信息用于指示载波带宽部分A对应的功率控制参数A，则终端设备在载波带宽部分A接收上行信息；其中，如载波带宽部分A可以为本申请实施例中涉及的第一载波带宽部分，对应的上行信息可以为第一上行信息；载波带宽部分A可以为本申请实施例中涉及的第二载波带宽部分，对应的上行信息可以为第二上行信息。
又例如，若功率控制参数指示信息用于指示第一载波带宽部分对应的第一功率控制参数和第二载波带宽部分对应的第二功率控制参数，则终端设备在第一载波带宽部分接收第一上行信息，以及在第二载波带宽部分接收第二上行信息；其中，第一上行信息的发射功率为第一发射功率，第二上行信息的发射功率为第二发射功率。
当然，功率控制参数指示信息还可以用于指示其它数量个载波带宽部分对应的功率控制参数，对应地，终端设备在各载波带宽部分分别接收终端设备发送的上行信息。
本申请实施例中，网络设备通过向终端设备发送功率控制参数指示信息，以便终端设备根据接收到的功率控制参数指示信息确定出第一载波带宽部分对应的第一功率控制参数以及第二载波带宽部分对应的第二功率控制参数；进一步地，终端设备在第一载波带宽部分上根据第一发射功率(根据第一功率控制参数确定的)向网络设备发送第一上行信息，以及在第二载波带宽部分上根据第二发射功率(根据第二功率控制参数确定的)向网络设备发送第二上行信息。可见，实现了网络设备根据载波带宽部分的不同为终端设备配置不同的功率控制参数，以便终端设备在同一载波的不同载波 带宽部分上可以采用不同的发射功率发送信息，从而保证了在载波带宽部分切换时的上行信号质量(或上行覆盖)。
通常情况下，不同的PUCCH有效载荷大小使用不同的PUCCH格式，其中，有效载荷是指该PUCCH承载的信息比特量，不同的PUCCH格式对于不同的编码调制方式。例如，PUCCH有效载荷较大的使用PUCCH格式4或者PUCCH格式5，PUCCH有效载荷较小的使用PUCCH格式1或者PUCCH格式2。
考虑到PUCCH格式1或者PUCCH格式2承载的PUCCH有效载荷较小，其正交复用能力较强，即允许较多的用户通过使用不同的循环移位在同一个RB中发送各自的PUCCH，则当频率分集增益恶化时，可以通过减少复用获得频率分集增益，因此其对于频率分集增益的恶化不敏感，可以不需要考虑在载波带宽部分切换时进行功率补偿。但PUCCH格式4或者PUCCH格式5承载的PUCCH有效载荷较大，其正交复用能力较弱，则其对于频率分集增益的恶化较为敏感，需要考虑在载波带宽部分切换时进行功率补偿。

可见，本申请实施例中，通过网络设备不需要为每种PUCCH格式都配置多个功控参数，从而可以减少网络设备发送功率控制指示信息的信令开销。
