Uplink transmission resource determining method and apparatus
An uplink transmission resource determining method includes: receiving first system information sent by a network device, where the first system information includes a first physical uplink shared channel (PUSCH) resource configuration; determining whether a preset condition is met; receiving second system information sent by the network device when the preset condition is not met, where the second system information includes a second PUSCH resource configuration; and determining, based on the second PUSCH resource configuration, a parameter used for uplink transmission. In this way, a terminal may flexibly select the PUSCH resource configuration in the first system information or the PUSCH resource configuration in the second system information based on a requirement of the terminal. The second system information is received only when the preset condition is not met, to reduce information obtained by the terminal and reduce power consumption of the terminal.
