Embodiment Construction

[0031] Embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

[0032] In some scenarios, such as power-constrained scenarios, or scenarios that require extremely high signal quality, such as Ultra Reliable and Low Latency Communication (URLLC), massive Machine Type of Communication (massive Machine Type of Communication, mMTC), repeated transmission is very necessary.

[0033] Repeated sending mainly refers to sending the same source signal multiple times. Transmission parameters for multiple transmissions of the same source signal may or may not be the same. The transmission parameters include at least one of the following: time domain resource parameters, frequency domain resource parameters, and air domain resource parameters. The airspace resources include at least one of multiple-input multiple-output (Multiple-Input Multiple-Output, MIMO) transmission-related parameters and beam-related parameters. When...

Description

technical field [0001] The present application relates to wireless communication networks, for example, to a power control method, device and system. Background technique [0002] One of the key features of the fifth generation mobile communication system (5th Generation, 5G) is to support high frequency bands. The high frequency band has abundant frequency domain resources, but there is a problem of limited coverage due to rapid attenuation of wireless signals. [0003] Sending signals by means of beam properties can concentrate energy in a relatively small space range, thereby improving the coverage of high-frequency signals. In addition, 5G New Radio (NR) technology also needs to support different types of application scenarios. In some scenarios, such as power-limited scenarios or scenarios that require extremely high signal quality, repeated transmission is also an enhancement technology for NR that needs to be supported. characteristics. [0004] Repeated transmissi...
