Method and user equipment for ensuring parallel data random access

摘要

The present invention relates to the technical field of communications. Disclosed in an embodiment of the present invention are a method and user equipment (UE) for ensuring parallel data random access, the method comprising: ensuring that a random access preamble transmitted by the UE via a physical random access channel (PRACH) is not transmitted in the same subframe with other uplink transmissions; alternatively, when the random access preamble transmitted by the UE via the PRACH is transmitted in the same subframe with other uplink transmissions, controlling the priority of the transmission power of the uplink channel that the PRACH and the other uplink transmissions are in when the power is limited. The embodiment achieves ordered transmission of the random access preamble and other uplink transmissions, or achieves concurrent transmission of the random access preamble and other uplink transmissions, thus avoiding the conflict between uplink transmissions and random access process during parallel data random access.
