    Abstract: Methods, systems, and devices for wireless communication are described. One method includes identifying a plurality of intermediate precoders corresponding to a plurality of tone subsets. The plurality of intermediate precoders define a plurality of vectors across the plurality of tone subsets. The method further includes selecting, for each vector of the plurality of vectors, a subset of non-frequency domain components of the vector, such as time-domain components; modifying the plurality of intermediate precoders to a plurality of smoothed precoders based at least in part on the selected subset of non-frequency domain components for each vector; and precoding a plurality of transmit streams using the plurality of smoothed precoders. The plurality of smoothed precoders is smoothed in a frequency domain compared to the plurality of intermediate precoders. Smoothing precoders may enable application of wideband channel estimation techniques using user equipment (UE)-specific reference signals.

    Abstract: Systems and techniques are disclosed to reduce pilot overhead by providing common reference signals coded with cover codes that are orthogonal in time and frequency domains. Common reference signals that are coded by cover codes orthogonal in both domains can be de-spread in both the time and frequency domains for improved resolution and larger pull-in windows. Semi-uniform pilot spacing in both the frequency and time domains can be utilized. In time domain, a first pilot symbol pair is spaced by a first time interval and a second pilot symbol pair is spaced by a second time interval from the first pair, the second interval being greater than the first. In frequency domain, a first set of pilot symbols is densely placed in a selected frequency band and a second set of pilot symbols is sparsely placed surrounding and including the selected frequency band.

    Abstract: The various embodiments provide circuitry and methods for packing Log Likelihood Ratio ("LLR") values into a buffer memory in a compressed format which reduces the amount of buffer memory required. Various embodiments use a type of quantization which reduces the bit width of the LLR values that are stored, with the particular level of quantization depending upon the code rate of the data. The degree, pattern, and periodicity of bit width compression employed may depend upon the code rate of the received transmission. Bit width patterns use for LLR value quantization may be generated by a shift register circuit which provides an efficient mechanism for controlling an LLR packer circuit based upon the code rate of the received signal.
