- and
- calculating transmit power of the PRACH based on the path loss;
- wherein the step of calculating a path loss of a physical random access channel PRACH based on power information related to a synchronization broadcast signal block comprises;
- calculating the path loss of the PRACH based on transmit power of the synchronization broadcast signal block and a power offset between a channel state information reference signal (CSI-RS) and the synchronization broadcast signal block, wherein the power offset is configured by a network device.
A terminal, wherein the terminal comprises a processor, a memory, and a computer program stored in the memory and capable of running on the processor, and when the computer program is executed by the processor, steps of a power control method for a physical random access channel are implemented, the method comprising:
- calculating a path loss of a physical random access channel (PRACH) based on power information related to a synchronization broadcast signal block;
- and
- calculating transmit power of the MACH based on the path loss;
- wherein the step of calculating a path lass of a physical random access channel PRACH based on power information related to a synchronization broadcast signal block comprises;
- calculating the path loss of the PRACH based on transmit power of the synchronization broadcast signal block and a power offset between a channel state information reference signal (CSI-RS) and the synchronization broadcast signal block, wherein the power offset is configured by a network device.
A non-transitory computer-readable storage medium, wherein the computer-readable storage medium stores a computer program, and when the computer program is executed by a processor, steps of a power control method for a physical random access channel are implemented, the method comprising:
- calculating a path loss of a physical random access channel (PRACH) based on power information related to a synchronization broadcast signal block;
- and
- calculating transmit power of the PRACH based on the path loss;
- wherein the step of calculating a path loss of a physical random access channel PRACH based on power information related to a synchronization broadcast signal block comprises;
- calculating the path loss of the PRACH based on transmit power of the synchronization broadcast signal block and a power offset between a channel state information reference signal (SCI-RS) and the synchronization broadcast signal block, wherein the power offset is configured by a network device.
