Abstract
A method includes: obtaining, by a terminal, configuration information, wherein the configuration information comprises a maximum quantity of signal transmitting attempts corresponding to each coverage enhancement level; determining, by the terminal according to the obtained configuration information, a transmit power used for transmitting the signal at a coverage enhancement level currently used by the terminal; and transmitting the signal using the determined transmit power.
Claims20
A computer program product comprising computer-executable instructions for storage on a non-transitory computer readable medium that, when executed by a processor, cause an apparatus to:
- obtain configuration information, wherein the configuration information comprises a maximum quantity of attempts of transmitting a signal corresponding to each of a plurality of coverage enhancement levels;
- determine, according to the configuration information, a transmit power used for transmitting the signal at a coverage enhancement level currently used by the apparatus;
- and
- transmit the signal using the transmit power, wherein the signal comprises a random access preamble sequence.
A computer program product comprising computer-executable instructions for storage on a non-transitory computer readable medium that, when executed by a processor, cause an apparatus to:
- obtain configuration information, wherein the configuration information comprises a quantity of repetition times required for a signal to be transmitted at a coverage enhancement level currently used by the apparatus;
- determine, according to the quantity of repetition times, a transmit power used for transmitting the signal at the coverage enhancement level currently used by the apparatus;
- and
- transmit the signal using the transmit power, wherein the signal comprises a random access preamble sequence.
A computer program product comprising computer-executable instructions for storage on a non-transitory computer readable medium that, when executed by a processor, cause an apparatus to:
- configure configuration information, wherein the configuration information indicates a power compensation value for each of a plurality of coverage enhancement levels, wherein the configuration information comprises a quantity of repetitions for a signal to be received at each coverage enhancement level, and wherein there is a correspondence between the quantity of repetitions and the power compensation value for each of the plurality of coverage enhancement levels;
- and
- transmit the configuration information to a terminal served by the apparatus.
