One notable patent is a "Device discovery using distributed random access for device-to-device communication." This invention proposes a fast device discovery protocol that achieves a high success rate for device-to-device (D2D) communication within LTE-A networks. The protocol involves monitoring a randomly transmitted beacon from other devices in a defined time period. In this process, an eNB allocates distributed uplink resources for the random access of beacon transmission by the D2D user equipment (UEs), optimizing resource usage based on the number of D2D UEs and target discovery probability.

Another significant patent is related to "Multiple-input multiple-output systems and methods for wireless communication thereof for reducing the quantization effect of precoding operations utilizing finite codebooks." This patent provides a method to mitigate quantization effects in MIMO systems by obtaining downlink channel state information at the receiver and selecting indices of precoding matrices from a set of finite codebooks. The refined precoding matrices generated based on these selections play a crucial role in enhancing transmission quality between the transmitter and receiver.
