Claim 11:
12. A non-transitory computer readable storage medium, wherein the computer readable storage medium stores a computer readable instruction, and when a computer reads and executes the computer readable instruction, the computer is caused to perform the following:
obtaining a grant-free (GF) resource configured by a base station;
obtaining a target service corresponding to to-be-transmitted data;
responsive to determining that the target service is not in a preset list, transmitting the to-be-transmitted data by using the GF resource, or
responsive to determining that the target service is in the preset list, obtaining a current channel quality;
comparing the current channel quality with a first preset range and a second preset range, wherein the first preset range is different from the second present range; and
in response to the current channel quality being a first channel quality, transmitting the to-be-transmitted data by using the GF resource, or transmitting the to-be-transmitted data by using a grant-based (GB) resource, wherein the first channel quality falls within the first preset range, or
in response to the current channel quality being a second channel quality, skipping transmitting the to-be-transmitted data by using the GF resource, wherein the second channel quality falls within the second preset range;
wherein the first channel quality is better than the second channel quality;
wherein a parameter related to the current channel quality comprises:
at least one of a reference signal received power (RSRP), reference signal received quality (RSRQ), a reference signal carrier-to-interference-and-noise ratio (RS-CINR), or a path loss (PL) of a channel corresponding to the current channel quality;
wherein:
the first channel quality meets at least one of the following: the RSRP is greater than a first threshold, the RSRQ is greater than a second threshold, the RS-CINR is greater than a third threshold, or the PL is less than a fourth threshold; and
the second channel quality meets at least one of the following: the RSRP is less than the first threshold, the RSRQ is less than the second threshold, the RS-CINR is less than the third threshold, or the PL is greater than the fourth threshold;
wherein the obtaining, by the terminal device, the GF resource configured by the base station comprises: receiving, by the terminal device, GF configuration information sent by the base station;
wherein the method further comprises:
performing, by the terminal device, a calculation based on the GF configuration information, to determine the first preset range and the second preset range; and
wherein the performing, by the terminal device, the calculation based on the GF configuration information, to determine the first preset range and the second preset range comprises:
performing, by the terminal device, a calculation according to a first preset formula based on a maximum transmit power, PCMAX, of the terminal device, a reference transmit power, PT,RS of a downlink signal, and the GF configuration information, to obtain the first threshold.
