Herein described are apparatuses, systems, and methods for measurement and reporting of channel state information within wireless network systems. In embodiments, an apparatus for a user equipment (UE) may include memory to store a rank indicator (RI), a precoding matrix index (PMI), and a channel quality indicator (CQI) of channel state information (CSI) for the UE. The apparatus may further include circuitry to concatenate the RI, the PMI, and the CQI to produce a concatenated CSI element, generate a CSI report that includes the concatenated CSI element, and cause the CSI report to be transmitted to a base station within a single slot. Other embodiments may be described and/or claimed.

A communication device for uplink transmission with a first type of information and a second type of information includes a demultiplexing circuit, a vector selection circuit, a permutation circuit and a Reed-Muller encoding circuit. The demultiplexing circuit generates a first group of information bits and a second group of information bits according to the first type of information and the second type of information. The vector selection circuit selects code vectors from a predetermined vector set for the first group of information bits and the second group of information bits. The permutation circuit permutes the code vectors according to the first group of information bits and according to the second group of information bits. The Reed-Muller encoding circuit encodes the first group of information bits and the second group of information bits with the permuted code vectors for providing different levels of protection.

Methods are disclosed for improving communications on feedback transmission channels, in which there is a possibility of bit errors. The basic solutions to counter those errors are: proper design of the CSI vector quantizer indexing (i.e., the bit representation of centroid indices) in order to minimize impact of index errors, use of error detection techniques to expurgate the erroneous indices and use of other methods to recover correct indices.
