SRS BASE SEQUENCE FOR EXTENDED COMB4 MODE

WIPO Patent Application WO/2017/075812

A1

The present disclosure describes embodiments for reducing collisions for SRS transmitted to cells using comb4 mode and comb2 mode. In an embodiment, the SRS data included in the SRS signals is reordered such that SRS signals transmitted to a cell operating in comb4 mode do not collide with SRS signals transmitted to a cell operating in comb2 mode. In an additional or alternative embodiment, the SRS signals transmitted to a cell operating in comb4 mode are redefined such that the SRS signals transmitted to the cell operating in comb 4 mode do not collide with SRS signals transmitted to a cell operating in comb2 mode.
