    • An apparatus and method for symbol decoding comprising selecting a degree of freedom (DOF) parameter for a noise vector; selecting a delta probability value; computing a cost function for a lattice point that is one of a discrete set of nominal codeword positions in a hypersphere; selecting a sphere decoding radius based on the DOF parameter, the delta probability value and the cost function; and decoding a symbol using the sphere decoding radius. And, the apparatus and method comprising setting pre-defined threshold probabilities; computing threshold radii based on the pre-defined threshold probabilities; setting an initial sphere radius square to the value of a first threshold radii; finding the Lattice point based on the initial sphere radius square; computing an updated sphere radius square as the minimum of either a cost function or a second threshold radii; and finding a next lattice point based on the updated sphere radius square.

    • TDD devices may transmit using multiple antennas. First and second antennas having first and second receive conditions may receive a communication. In an aspect, first and second transmit conditions for the first and second antennas may be determined based on the first and second receive conditions. In an aspect, the first and second transmit conditions may be compared to select the first or second antenna for transmissions. In an aspect, the first and second receive conditions may be compared to select the first or second antenna for transmissions. In an aspect, first and second transmission conditioning values, which may determine transmission powers, may be determined based on the first and second receive conditions. A first transmission chain, associated with an active radio access technology (RAT) or carrier, and a second transmission chain, associated with an inactive RAT or carrier, may be activated to send transmissions from the first and second antennas.
