Claim of US Patent No. 10,602,525

9. A method of wireless communication, comprising:advertising a physical random access channel (PRACH) configuration that has PRACH resources comprising only subframes that are pre-defined uplink subframes for time division duplex (TDD) configurations available at a base station or a subset of the TDD configurations, the PRACH configuration being unavailable in legacy user equipments (UEs); and when a contention-based PRACH process is used:
scheduling a random access response and a contention resolution message of the PRACH process on downlink subframes such that a corresponding scheduled transmission and an acknowledgement (ACK) message for the contention resolution message are transmitted on subframes that are the pre-defined uplink subframes for the time division duplex (TDD) configurations available at the base station or the subset of the TDD configurations available at the base station; or
defining a new timeline for the scheduled transmission and the ACK message for the contention resolution message, the new timeline including transmissions on subframes that are the pre-defined uplink subframes for the TDD configurations available at the base station or the subset of the TDD configurations available at the base station.
