Claim of US Patent No. 10,143,011

1. A method for processing channel access performed by user equipment, comprising:receiving a fallback to physical random access channel (PRACH) configuration sent by a base station;
configuring, in response to the received fallback to PRACH configuration, the user equipment to allow a discontinuous reception (DRX) state or a short-DRX state of enhanced DRX and prohibit a long-DRX state of the enhanced DRX by triggering the user equipment to fall back to the short-DRX state from the long-DRX state if the user equipment is in the long-DRX state;
receiving a fallback to PRACH indication sent by the base station;
initiating access on PRACH in response to the received fallback to PRACH indication;
entering a continuous reception state in response to the received fallback to PRACH indication; and
if a timer that triggers entering the DRX state is running when the fallback to PRACH indication is received, stopping the timer.
