Title:
復調基準信号（ＤＭＲＳ）において配信される情報のための保護の提供
Document Type and Number:
Japanese Patent JP7210484
Kind Code:
B2
Abstract:
Methods, systems, and devices for wireless communication are described. A device—such as a base station or user equipment (UE)—may transmit a demodulation reference signal (DMRS) including signaling information in addition to channel estimation information. To improve reception of the DMRS signaling information, the transmitting device may employ data protection techniques to the signaling information and modify a data payload transmitted in the physical data channel associated with the DMRS. In one aspect, the transmitting device may modify cyclic redundancy check (CRC) bits in the payload to include verification for the signaling information. In another aspect, the transmitting device may determine a scrambling code based on the signaling information, and may scramble the payload based on the scrambling code.
