This disclosure relates to techniques for performing long term evolution cell specific reference signal rate matching for new radio physical downlink shared channel resource mapping in a wireless communication system. A wireless device may establish a wireless link with a fifth generation new radio cell. Information indicating to perform long term evolution cell specific reference signal rate matching for a physical downlink shared channel for the cell for a long term evolution carrier may be received by the wireless device. A set of rate matching patterns may be selected by the wireless device. Long term evolution cell specific reference signal rate matching for the physical downlink shared channel for the cell may be performed by the wireless device for the long term evolution carrier using the selected set of rate matching patterns.

LTE CRS rate matching for 5G NR PDSCH resource mapping

An equalizer includes: a channel estimator configured to generate a set of time-domain channel coefficients based on a receive signal; a frequency-domain transformer configured to generate a set of frequency-domain channel coefficients based on a frequency transform of the set of time-domain channel coefficients; an equalizer coefficient generator configured to generate a set of frequency-domain equalizer coefficients based on the set of frequency-domain channel coefficients; a time-domain transformer configured to generate a set of time-domain equalizer coefficients based on a time transform of the set of frequency-domain equalizer coefficients; and a filter configured to filter the receive signal based on a filter function that is based on the set of time-domain equalizer coefficients.

Equalizer and method for equalizing a receive signal

One embodiment of the present invention relates to a transceiver. The transceiver includes a transmitter having a first transmission path configured to transmit a digital baseband signal over a wireline medium. In addition, the transmitter has a second transmission path configured to transmit a radio frequency signal over a wireless medium. Other systems and methods are also disclosed.
