Title:
APPARATUS AND METHOD IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/223982
Kind Code:
A1
Abstract:
An apparatus and a method in a wireless communication system. The apparatus comprises a processing circuit, the processing circuit being configured to: determine an idle resource element in a P2 process and/or a P3 process based on a channel state information-reference signal (CSI-RS) mapping structure, wherein only a transmission beam is scanned in the P2 process, only a reception beam is scanned in the P3 process, and the idle resource element refers to a resource element which is not occupied by a CSI-RS in an OFDM symbol occupied by the CSI-RS; and when the P2 process and/or the P3 process is carried out, control a base station so that same uses the idle resource element to send data and/or control information to a user equipment.
