Claim of US Patent No. 10,560,967

1. A method for channel transmission of a remote node, the method comprising:intermittently receiving a forward channel transmitted from a host node,
wherein the receiving of the forward channel comprises,
measuring a state of the forward channel for a first period by enabling an operation of a receiver of the remote note for the first period, and stopping a measurement of the state of the forward channel for a second period by disabling the operation of the receiver for the second period,
wherein the first period and the second period are arranged in a flow of time repetitively, and a measurement interval is adjusted based on inverse proportion to a change of a Doppler frequency of the received forward channel,
wherein the measurement interval is a time interval between the first periods arranged in a flow of time repetitively;
determining whether the state of the forward channel satisfies a preset channel condition to transmit a random access channel (RACH); and
transmitting the random access channel (RACH) based on the determined result,
wherein the measuring the state of the forward channel is intermittently performed to estimate a transmission power for transmitting the random access channel (RACH) until the random access channel (RACH) is transmitted, and
wherein the measuring the state of the forward channel is intermittently performed after a triggering event for the random access channel (RACH) transmission occurred.
