摘要： An apparatus and method for generating a Channel Quality Indicator (CQI) in a wireless communication system are provided. The method includes receiving a Modulation and Coding Scheme (MCS) index and resource allocation information of a traffic channel and calculating a spectral efficiency at a particular time point, determining a temporary CQI index having a spectral efficiency closest to the calculated spectral efficiency in an index set, reading a CQI metric a time τ before the particular time point, determining, if the temporary CQI index is reported at the particular time point, an error rate based on the CQI metric, the error rate being a probability of an error occurring in a traffic channel after the time τ, receiving an error check result of the traffic channel transmitted at the particular time point and calculating a new error rate by applying a weight to the error check result and the error rate, and determining a CQI index to be fed back to a transmitter using the new error rate. Hence, the CQI index which maximizes spectral efficiency is determined and a Physical Downlink Shared CHannel (PDSCH) acknowledgement (ACK)/negative acknowledgement (NACK) probability is directly estimated adaptively according to a change in channel, thereby providing useful performance in various channel environments.

摘要： Provided is an apparatus and method for controlling an interleaver/deinterleaver memory in a mobile communication system are provided. In particular, an apparatus and method are provided which can reduce unnecessary time and power consumption by eliminating an unnecessary memory erasure. A write address generator generates write addresses. A memory stores values mapped to the write addresses. A memory controller controls the memory in which an input signal is accumulated to a value stored at a write address which is then recorded at the write address if the value stored at the write address is recorded for a previous packet when the input signal is generated. The memory controller controls the memory in which the input signal is recorded at the write address if the value stored at the current record address is a valid value for a current packet.
