A sensor inserter for a physiological characteristic sensor includes a housing that defines a track system that extends from a bottom of the housing toward a top of the housing. The sensor inserter includes a striker assembly movable relative to the housing between a first state, a second, cocked state and a third, disposal state. The striker assembly is movable from the second, cocked state to the third, disposal state to couple the physiological characteristic sensor to an anatomy. The striker assembly includes a lock beam that engages with the track system as the striker assembly moves between the first state, the second, cocked state and the third, disposal state. In the third, disposal state the lock beam inhibits movement of the striker assembly from the third, disposal state to the first state.

Data packet retransmission by a radio link control (RLC) protocol entity of a transmit end is described herein. The retransmission includes sending a target sequence number and a first data packet to a MAC entity of the transmit end and recording a quantity of times the target sequence number is transmitted to the MAC entity of the transmit end at an RLC layer. In accordance with receiving the target sequence number and a negative acknowledgement that are sent by the MAC entity, obtaining the RLC layer transmission count corresponding to the target sequence number. In accordance with determining the RLC layer transmission count is less than an RLC layer transmission threshold, sending a retransmission instruction based on the first data packet to the MAC entity. In accordance with a retransmission condition at the RLC layer being met, the RLC entity of the transmit end triggers retransmission at the RLC layer.
