Latest Patents
One of Edholm's latest patents is titled "Power level of transmitted control channel symbol." This invention improves channel estimation accuracy by adjusting the power level of a physical control channel allocated to a receiver based on the transmission rate and/or transport format of a corresponding physical data channel. The physical control channel may include various types such as DPCCH or E-DPCCH, facilitating both uplink and downlink communication. Control channel symbols are transmitted at an adjusted power level, allowing the receiver to perform effective channel estimation.
Another significant patent is the "Method and system for providing autonomous retransmissions in a wireless communication system." This invention enables a transmitter with limited power availability to autonomously retransmit previously sent frames containing the same data. The transmitter sends an initial frame to a base transceiver station and immediately retransmits the same frame without waiting for an acknowledgment. The receiver accumulates these retransmissions and decodes them after a sufficient quantity has been received.
