METHOD, TERMINAL AND SYSTEM FOR CLUSTER TERMINAL TO FEED BACK DOWNLINK CHANNEL INFORMATION
First Claim
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.

Abstract
A method, a terminal and a system for a cluster terminal to feedback downlink channel information are provided. In the method, a cluster terminal in an idle state configures a group call context and measures a current downlink channel in a preset period, after a group call signaling sent by a base station is received; sends a RRC connection request carrying a measurement result to the base station after determining that the measurement result meets a preset report triggering condition, where 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 receives group call data according to the instruction after the instruction is received.

10. A system for feeding back downlink channel information, comprising:
-
a cluster terminal, and a base station, wherein the base station is configured to send a group call signaling to the cluster terminal; the cluster terminal is configured to configure a group call context and measure a current downlink channel in a preset period after the group call signaling is received, and send an RRC connection request carrying a measurement result to the base station after determining that the measurement result meets a preset report triggering condition; the base station is configured to modify an air interface resource configuration after receiving the RRC connection request carrying the measurement result sent by the cluster terminal and determining that a preset condition for modifying the air interface resource configuration is met according to the measurement result, and send an instruction carrying the modified air interface resource configuration to the cluster terminal; and the cluster terminal is further configured to receive group call data according to the instruction after the instruction is received.

11. A cluster terminal, comprising:
-
a receiver, a transmitter, and a processor;
wherein the processor is configured to;configure a group call context and measures a current downlink channel in a preset period after a group call signaling sent by the base station is received by the receiver; send an RRC connection request carrying a measurement result to the base station via the transmitter 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 receive group call data according to the instruction after the instruction is received by the receiver. - View Dependent Claims (12, 13, 14, 15, 21, 22, 23)
