Title:
SIGNAL PROCESSING METHOD AND COMMUNICATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/179670
Kind Code:
A1
Abstract:
Provided in the present application are a signal processing method and a communication apparatus. In the method, a first device can determine P resource elements among L resource elements from among resource elements corresponding to a first time-domain symbol, wherein the P resource elements are used for mapping a first reference signal, which is about to be sent to a second device, and resource elements, other than the P resource elements, among the L resource elements do not send any signal. Any two of the L resource elements are spaced by resource elements, the number of which is an integral multiple of M, and the first reference signal, which is received by the second device on a specific sampling point, will not be interfered with by signals which are mapped on resource elements, other than the L resource elements, corresponding to the first time-domain symbol. The second device can measure the energy of different sampling points of the first reference signal in the time domain, so as to realize the measurement of different beams, such that not only can the accuracy of beam measurement be improved, but also a plurality of beams can be trained in one time-domain symbol, thereby reducing resource overheads.
