Document Type and Number:
WIPO Patent Application WO/2023/212881
Kind Code:
A1
Abstract:
Disclosed in the embodiments of the present disclosure are a demodulation reference signal (DMRS) transmission method, and an apparatus. The method comprises: a network-side device determining that a conflict condition is satisfied (S61); generating an additional DMRS (S62); and transmitting a cell-specific reference signal (CRS) and the additional DMRS by means of an orthogonal cover code (OCC) (S63). Therefore, an NR PDCCH and an LTE CRS are simultaneously transmitted by means of an OCC, and an additional DMRS is transmitted on a resource which is occupied by CRS transmission, such that the capacity of the NR PDCCH can be improved, and the transmission performance is improved.
