Embodiments of methods in a base station and a UE are disclosed. In some embodiments, a method implemented in a network node includes any one or more of: selectively puncturing transmission of LTE CRS symbols that overlap NR DMRS symbols in a downlink transmission time interval; selectively puncturing transmission of NR DMRS symbols that overlap LTE CRS symbols in the downlink transmission time interval; and selectively reducing a number of NR DMRS symbols transmitted to the UE in the downlink transmission time interval. In some embodiments, a method implemented in a UE includes identifying, in a downlink channel, subchannels containing NR DMRS symbols that are corrupted due to collision with LTE CRS symbols. For each identified subchannel: a respective time averaged channel estimate is determined based on NR DMRS symbols that are not corrupted due to collision with the LTE CRS symbols; and a respective MMSE weight is determined using the time averaged channel estimate.
