1. A method for a cluster terminal to feedback downlink channel information, comprising:

  • configuring, by a cluster terminal in an idle state, a group call context and measuring a current downlink channel in a preset period, after a group call signaling sent by a base station is received;

    sending, by the cluster terminal, a radio resource control, RRC, connection request carrying a measurement result to the base station after determining that the measurement result meets a preset report triggering condition, wherein the base station modifies an air interface resource configuration when determining that a preset condition for modifying the air interface resource configuration is met according to the measurement result, and sends an instruction carrying the modified air interface resource configuration to the cluster terminal; and

    receiving, by the cluster terminal, group call data according to the instruction after the instruction is received.
