Latest Patents

Frederic holds a patent titled "Procedure to determine radio link condition using radio link control layer observations." This patent describes a method for controlling the performance of a radio link between a base transceiver station and a radio terminal. The invention allows a radio network controller (RNC) to monitor a directly observable L-parameter and determine a threshold violation without explicit L-L signaling. This capability enables the RNC to trigger a status change of the radio link effectively. The L-radio resource management algorithm prompts both the radio terminal and the RNC to take necessary actions whenever the L-parameter violates a specified threshold. Such actions may include downgrading or upgrading the transmission rate or reconfiguring the radio link. The L-parameter can refer to the radio block error rate or the PDU retransmission rate.
