Title:
METHOD AND DEVICE FOR COMMUNICATION
Document Type and Number:
WIPO Patent Application WO/2019/214737
Kind Code:
A1
Abstract:
A method and device for communication. The method comprises: a first terminal side device determining a frequency domain resource of a scheduled first physical downlink shared channel (PDSCH), wherein the first PDSCH corresponds to a first demodulation reference signal (DM-RS) on a first antenna port; if the frequency domain resource comprises N consecutive frequency domain units, and each of Lconsecutive frequency domain units in the N frequency domain units has a second DM-RS on a second antenna port, the first terminal side device determining that pre-coding of the second DM-RS in each frequency domain unit of the L frequency domain units is the same, wherein the second DM-RS and the first DM-RS belong to the same code division multiplexing CDM group, and the second DM-RS corresponds to a scheduled second PDSCH of a second terminal side device; N is an integer greater than one, L is less than or equal to N, and is an integer greater than one.
