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).

Abstract: A priority-resource-limited CoMP scheme is proposed based on a coordination priority index of users which comes into play to perform cooperation set selection and resource allocation in small cell networks. The CoMP control unit (CCU) configures and then transmits to the donor (serving) Transmission/Reception Point (TRP) the coordination priority index which is determined as a function of the required Bit Rate for that specific User Equipment (UE) and the SINR or the CQI. The donor Transmission/Reception Point (TRP) then transmits the coordination priority indexes sent by the CCU to the corresponding User Equipment (UE)s. The configuration of the coordination priority index allows the User Equipment (UE) to select a subset of Channel State Information (CSI) reports or Channel State Information (CSI) quantities to report so that the threshold index of the coordination priority is met.
