Abstract: A method and an apparatus in a multiple-input multiple-output (MIMO) wireless communication system are provided. A signal is received over a channel. The channel is decomposed into a plurality of virtual channels. Symbol detection is performed on each of the plurality of virtual channels using respective symbol detectors. At least one of the symbol detectors has a lower rank than that of the channel. Output from the symbol detectors is combined to obtain final log likelihood ration (LLR) values for layers of the channel. Decoding is performed using the final LLR values to output a decoded symbol value of the received signal.

Abstract: A method and apparatus are provided. The method includes, but is not limited to, receiving a universal synchronization signal (USS) including a universal primary synchronization signal (UPSS) and a universal secondary synchronization signal (USSS), wherein the USS is coded using a mother code which is extended to m resource blocks (RBs) and n orthogonal frequency division multiplexing (OFDM) symbols and a code cover of m RBs and n symbols is applied to the mother code, determining a cell identity based on the USS, determining a frame timing based on the USS, and connecting a user equipment to a network using the cell identity and the frame timing.
