Abstract: A system and a method for estimating a transmission channel of a communication link. A transmitter can transmit a first transmission signal and a receiver can receive the first transmission signal through the transmission channel. The first transmission signal includes data elements and pilots, each of the pilots being located at specified locations within a time-frequency domain of the first transmission signal. The receiver can determine a level of interference for each of the pilots, the level of interference being indicative of an extent of distortion on a respective pilot caused by a second transmission signal interfering with the first transmission signal. The receiver can further determine an interference-mitigated pilot for each pilot based on the determined level of interference determined for each respective pilot. The receiver can use the determined interference-mitigated pilots to estimate the transmission channel of the first transmission signal.

Abstract: A method of low-latency audio transmission in a mobile communications network utilizing first data frames or subframes encoded according to a first format and shorter second data frames encoded in another second format for audio data. An audio transmission system includes a terminal, a base station, and an audio receiver. The terminal transmits via an uplink audio data that are encoded in the second format and other data that are encoded in the first format. The audio receiver directly receives the audio data transmitted via the uplink. The encoding/decoding of the audio data of one of the second data frames is influenced by other audio data of the same second data frame but not by audio data of another second data frame. Audio transmission from the terminal to the audio receiver is effected in the allocated time slots and frequencies in a waveform in conformity with the mobile communications network.
