1. a kind of transmission method of Physical Random Access Channel, which is characterized in that this method comprises:

  • Under the scene of carrier wave polymerization, base station sends random access triggering message by main serving cell and gives user equipment (UE);

    The base station sends random access by main serving cell and triggers message to UE, comprising;

    the base station passes through in main serving cellDownlink control channel information send random access triggering message to UE, wherein in the downlink control channel information include instituteState the uplink auxiliary serving cell index where Physical Random Access Channel;

    The UE transmits physical accidental in auxiliary serving cell and connectsEnter channel;

    The base station sends random access procedure message to the UE in main serving cell;

    The UE is in the transmission objectIt manages and sends random access procedure message 3 in the auxiliary serving cell of random access channel to base station;

    Wherein, the base station is in main serviceRandom access procedure message is sent in cell to UE, specifically;

    the UE detect what base station was sent in the main serving cellDownlink Control Information, the UE detect the random access procedure message;

    The UE detects base station transmission in main serving cellDownlink Control Information, specifically;

    the UE is detected according to the random access radio network temporary identifier (RA-RNTI) of configurationDownlink Control Information, wherein the RA-RNTI of each serving cell configuration is different;

    Alternatively, the UE according to the RA-RNTI of configuration comeDownlink Control Information is detected, wherein the RA-RNTI of each serving cell configuration is identical;

    Alternatively, C- of the UE according to configurationRNTI detects Downlink Control Information;

    Alternatively,Under the scene of carrier wave polymerization, base station sends random access triggering message by auxiliary serving cell and gives user equipment (UE);

    UE transmitting physical random access channel in auxiliary serving cell;

    The UE transmits physical accidental access in auxiliary serving cellChannel, comprising;

    uplink auxiliary service of the UE in the downlink auxiliary serving cell SIBX link for receiving random access triggering messageIn cell, the Physical Random Access Channel is sent;

    The base station sent in auxiliary serving cell random access procedure message toThe UE;

    The UE sent in the auxiliary serving cell of the transmitting physical random access channel random access procedure message 3 toBase station;

    Wherein, the base station sends random access procedure message to UE in auxiliary serving cell, specifically;

    the UE detects baseIt stands the Downlink Control Information sent, the UE detects the random access procedure message in auxiliary serving cell;

    The UE detectionThe Downlink Control Information that base station is sent, specifically;

    the UE is detected in the auxiliary serving cell according to the RA-RNTI of configurationThe Downlink Control Information that base station is sent;

    Alternatively, under the UE is detected in the main serving cell according to the RA-RNTI of configurationRow control information, wherein the RA-RNTI of each serving cell configuration is different;

    Alternatively, UE root in the main serving cellDownlink Control Information is detected according to the RA-RNTI of configuration, wherein the RA-RNTI of each serving cell configuration is identical;

    Alternatively, describedUE detects Downlink Control Information according to the C-RNTI of configuration in the main serving cell;

    Alternatively, the UE is in the main clothesThe Downlink Control Information containing carrier wave instructions field is detected according to the RA-RNTI of configuration in business cell, wherein each serving cellThe RA-RNTI of configuration is identical.
