Abstract:
1. A method for allocation of parameters for radio transmission in a wireless communication network using channel feedback, comprising: determining a channel impulse response over a select time for an antenna link between transmitting network element and a receiving network element at the receiving network element based at least in part on transmissions over the antenna link from the transmitting network element received by the receiving network element; forming a power delay profile representative of the transmissions from the transmitting network element in conjunction with the select time based at least in part on the channel impulse response; assigning fingers in the power delay profile at delay times with a power higher than a predefined threshold in relation to the select time and associating each finger with its corresponding delay time; determining a complex coefficient for each finger in relation to the channel impulse response for the antenna link over the select time to form a compressed impulse response for the antenna link; and feeding back the complex coefficient and corresponding delay time for each finger in the compressed impulse response for the antenna link from the receiving network element to the transmitting network element.
