NOTE: If compressor uses CID field in compressed packet, the CID field should be included in the feedback packet and the Code and CID should be set as defined in [40]. â¦ The purpose of the base test case is to verify that the compressor properly implements
description: Cell ID (CID) is a parameter used in ROHC RTP O-mode compression, specifically in the computation of the CRC and in the construction of the feedback packet. It is an essential attribute for ensuring accurate and reliable data transmission.
explanation: The text describes CID as a parameter used within a specific technical context (ROHC RTP O-mode compression) and highlights its functional role in data transmission reliability.
