1. a kind of method for being used to send random access leader sequence based on LTE-TDD patterns at user equipment end, wherein the partyMethod includes the following steps:

  • Receive the system information that eNB is sent, wherein the system information includes the extension phase about cell corresponding to the eNBClose information;

    Wherein, this method further includes:

    Step b utilizes the U corresponding to LTE-TDD patterns according to the system informationPPTS sends user to the eNB and sets in advanceStandby random access leader sequence, wherein the pre-set time amount corresponding to the random access leader sequence corresponds to the expansionOpen up relevant information;

    Wherein, the extension relevant information includes cell extension radius, and the pre-set time amount is determined as follows:
