Title:
INDICATION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/141195
Kind Code:
A1
Abstract:
Disclosed in the present application are an indication method and device, for supporting the demands of complicated and diverse scenes. The method comprises: generating and sending an arrangement indication for indicating a reference signal, the reference signal occupying at least one group of time frequency resources, the arrangement mode being frequency division, time division, frequency division + code division or time division + code division mode; in the frequency division mode, each group of time-frequency resources occupying one symbol of the time domain and at least one continuous sub-carrier of the frequency domain; in the time division mode, each group of time-frequency resources occupying at least one continuous symbol of the time domain and one sub-carrier of the frequency domain; in the frequency division + code division mode, each group of time-frequency resources occupying one symbol of the time domain and at least one continuous sub-carrier of the frequency domain, the reference signal being multiplexed, by means of an orthogonal code corresponding to said reference signal, on said group of time-frequency resources; and in the time division + code division mode, each group of time-frequency resources occupying at least one continuous symbol of the time domain and one sub-carrier of the frequency domain, and the reference signal being multiplexed, by means of an orthogonal code corresponding to said reference signal, on said group of time-frequency resources.
