Abstract: A wireless terminal may receive downlink signaling over a downlink signaling channel from a base station, with the downlink signaling including a DTX indicator for a first downlink MIMO layer and a retransmission data indicator for a second downlink MIMO layer. Soft bits for the second MIMO layer may be generated for a TTI corresponding to the downlink signaling, and the soft bits may be decoded. After decoding the soft bits, an ACK message for the second MIMO layer may be transmitted responsive to success decoding the soft bits or a NACK message for the second MIMO layer may be transmitted responsive to failure decoding the soft bits, and a default response may be transmitted for the first MIMO layer for the TTI.

Abstract: Transmission quality is improved in an environment in which direct waves dominate in a transmission method for transmitting a plurality of modulated signals from a plurality of antennas at the same time. All data symbols used in data transmission of a modulated signal are precoded by hopping between precoding matrices so that the precoding matrix used to precode each data symbol and the precoding matrices used to precode data symbols that are adjacent to the data symbol in the frequency domain and the time domain all differ. A modulated signal with such data symbols arranged therein is transmitted.

Abstract: The invention relates to a MAP decoding method of a signal received through a noisy channel, the signal being composed of symbols in an alphabet having a non-uniform probability distribution, the symbols being represented by points in a lattice (Λ). The probability distribution of symbols is modeled using a Gaussian distribution. An augmented lattice (Λexp) is formed from the lattice (Λ) and the ratio (β) between variance of the noise and variance of the Gaussian distribution of symbols. Therefore, the disclosed MAP decoding method consists essentially of decoding using an ML criterion searching the point in the augmented lattice closest to the point representative of the received signal (yexp).
