インターレースされたFDM DMRSのためのコム適応
Document Type and Number:
Japanese Patent JP6976316
Kind Code:
Comb adaptation for interlaced frequency division multiplex (IFDM) demodulation reference signals (DMRS) is discussed. Transmission configuration for DMRS may be assigned to UEs with a coded combination of cyclic shift, orthogonal cover code, OCC, and a comb value. Some assigned combinations provide for a different comb value to be used for the different slots in the same subframe. Further aspects provide additional interference randomization through comb shifting, using inter-subframe hopping functions.
