Abstract: A transmitter that may have marginal power availability is enabled to autonomously retransmit previously transmitted frames containing the same data. The transmitter sends an initial frame to a base transceiver station (BTS) and immediately retransmits the same frame without regard to any ACK/NAK transmission from the BTS. The retransmissions are accumulated in the receiver and decoded after a sufficient quantity of the frame is transmitted. After receiving the last retransmitted frame the BTS sends an ACK/NAK to the transmitter that is accepted.

Abstract: A TRANSMITTER THAT MAY HAVE MARGINAL POWER AVAILABILITY IS ENABLED TO AUTONOMOUSLY RETRANSMIT PREVIOUSLY TRANSMITTED FRAMES CONTAINING THE SAME DATA. THE TRANSMITTER SENDS AN INITIAL FRAME TO A BASE TRANSCEIVER STATION (BTS) AND IMMEDIATELY RETRANSMITS THE SAME FRAME WITHOUT REGARD TO ANY ACK/NAK TRANSMISSION FROM THE BTS. THE RETRANSMISSIONS ARE ACCUMULATED IN THE RECEIVER AND DECODED AFTER A SUFFICIENT QUANTITY OF THE FRAME IS TRANSMITTED. AFTER RECEIVING THE LAST RETRANSMITTED FRAME THE BTS SENDS AN ACK/NAK TO THE TRANSMITTER THAT IS ACCEPTED.

Abstract: A method of transmitting symbols used for channel estimation and a transmitter are disclosed. The transmitter comprises a baseband processor configured to adjust the power level of an enhanced dedicated physical control channel allocated to a receiver based on at least one of a transmission rate and a transport format of a physical data channel allocated to the receiver, and transmit control channel symbols to the receiver over the enhanced dedicated physical control channel at the adjusted power level for use by the receiver in performing channel estimation. A method of performing channel estimation at a receiver and a receiver are disclosed. The receiver comprises a baseband processor configured to detect control channel symbols received from an enhanced dedicated physical control channel allocated to the receiver at a power level corresponding to at least one of a transmission rate and a transport format of a physical data channel allocated to the receiver; and perform channel estimation based at least in part on the detected control channel symbols. The receiver is the mobile station 104 for downlink communication and the radio base station 102 for uplink communication and the transmitter is the radio base station 102 for downlink communication and the mobile station 104 for uplink communication.

Abstract: A node (2) for use in a cellular communication system having interfering signals and employing interference cancellation techniques for mitigating the interfering signals comprises means (24) for obtaining a signal value representing power of a first signal. The node (2) further comprises means (25) for obtaining a precancellation interference value representing powers of signals interfering with the first signal before the interference cancellation is employed. A predictor (23) is arranged for predicting a postcancellation interference value after the interference cancellation as a function of the precancellation interference value. An estimator (29) is connected to the predictor (23) and the means (24) for obtaining a signal value. The estimator (29) is arranged for estimating a signal-to-interference ratio as a ratio between the signal value representing the power of the first signal and the predicted postcancellation interference value.

Abstract: A load control method is described herein that enables a base station to broadcast three downlink signals including a busy indicator, a maximum resource indicator and a minimum resource indicator to a mobile terminal. In response to receiving the downlink signals, the mobile terminal limits the utilization of a resource (e.g., bit rate, transmission power, power offset) it uses to transmit data to the base station. The mobile terminal may also send an uplink signal including a resource request to the base station. The base station can use the resource request to change the downlink signals if needed. It is with the proper use of these uplink/downlink signals that the behavior of the base station can be automatically optimized to the load situation.
