Uplink transmit power control information determination for performing uplink sending

A terminal device comprising:

• a processor;
• and
• a non-transitory computer-readable medium including computer-executable instructions that, when executed by the processor, cause the terminal device to carry out an uplink transmit power control method comprising:
• receiving a control signaling sent by a radio access network device;
• learning, based on the control signaling, of a slot for a power control information required, by the terminal device, to perform uplink sending;
• and
• obtaining, in the slot for the power control information required for uplink sending, the power control information required to perform uplink sending,
• determining, using the power control information, a transmit power to perform uplink sending,
• wherein the uplink sending is performed using a plurality of consecutive slots, and
• wherein the determining the transmit power, for ones of the plurality of consecutive slots, is performed in accordance with a calculation mode-based determination performed according to the following supported calculation modes:
• an accumulation calculation mode wherein a transmit power of a subsequent slot after a first slot in the plurality of consecutive slots is same as a first transmit power of the first slot of the plurality of consecutive slots;
• an absolute value calculation mode, where each one of the plurality of consecutive slots is treated individually, where a serial number of the first slot in the plurality of consecutive slots is i and corresponds to an offset k, and where a serial number of a subsequent slot is i+n and sequentially corresponds to a slot offset k+n, and in such case learning, based on the serial number of the slot and the corresponding slot offset by subtracting (k+n) from (i+n), of the slot of the power control information required by the terminal device to perform uplink sending, wherein i, k, and n are all natural numbers;
• and
• a slot group mode where the plurality of consecutive slots is treated as a slot group, wherein a serial number of the slot group is same as a serial number of the first slot in the plurality of consecutive slots, and learning, based on the serial number of the slot group and the slot offset information, of the slot of the power control information required by the terminal device to perform uplink sending in the slot group.
