    Abstract: It is desired to try to reduce power consumption in a transmit-and-receive point (TRP) in a wireless network. In some embodiments, to try to reduce overall power consumption, multiple (e.g. two) sets of radio frequency (RF) components are utilized by a TRP, one set having lower power consumption than the other set(s), and switching between the different sets during operation. For example, a TRP may include a first radio frequency unit (RFU) and a second RFU. The second RFU is designed to have higher power consumption than the first RFU. During operation, the TRP uses the second RFU to perform wireless communication in response to a trigger, and otherwise uses the first RFU to perform wireless communication.

    Abstract: A bandwidth resource switching method and apparatus are provided. When a network device sends bandwidth resource indication information to a terminal by using downlink control information, the network device may impose some constraints on uplink transmission mode-related configuration information or SRS-related configuration information on an indicated bandwidth resource, and other indication information carried in the downlink control information, so that no ambiguity occurs when the terminal parses the bandwidth resource indication information. Alternatively, when a side of a terminal receives bandwidth resource indication information sent by a network device by using downlink control information, the terminal parses, in an unambiguous interpretation manner, configuration information on a bandwidth resource indicated by the bandwidth resource indication information in the downlink control information. According to the application, a BWP is smoothly switched to perform uplink transmission, uplink transmission efficiency can be improved, and system robustness can be improved.

    Abstract: This application discloses a data sending method, a data receiving method, and a related apparatus. First phase rotation is performed on modulated data to obtain time domain rotated data. Frequency domain transform is performed on the time domain rotated data to obtain frequency domain data. Second phase rotation is performed on the frequency domain data to obtain frequency domain rotated data. Time domain transform is performed on the frequency domain rotated data to obtain time domain data. The time domain data is sent. Therefore, phase rotation may be separately performed on the modulated data and the frequency domain data based on an SC-FDMA waveform, to reduce a maximum amplitude of the time domain data and reduce a PAPR of the sent time domain data.
