It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further discussion thereof is necessary in subsequent figures.
The inventors found through research that: the super uplink technology requires that the 5G terminal schedules two uplink carriers in a TDM (Time-division multiplexing, time division multiplexing) manner, and transmits only on one carrier at a Time. Because the 5G terminals have high power (+26 dBm) transmission capability over the mainstream TDD spectrum, the additional FDD uplink carrier transmission power may cause the total terminal transmission power capability to exceed SAR regulatory requirements.
In view of at least one of the above technical problems, the present disclosure provides a super uplink power control method, a terminal, and a computer-readable storage medium.
The core ideas of the present disclosure are: by reducing power in exchange for more schedulable slot resources, FDD carriers are enabled to maximize use of resources under super uplink specifications.
The 3GPP standard generally considers that the terminal can achieve full slot transmission, i.e., FDD mode, at a maximum transmit power level of 23dBm, when SAR requirements are met, and the system design has no margin.
The test method, while taking into account SAR regulations, is based on an average power test over a period of time. Thus, when the terminal operates in NR (New Radio) SA (stand alone networking) high power mode (+26 dBm), the standard gives a maximum slot ratio (Duty Cycle) limit of 50% by default. So that the average power is equivalent to the FDD mode of 23 dBm.
