name: CSICH
full_form: CPCH Status Indicator Channel
context: CSICH is a fixed rate (SF=256) physical channel used to carry CPCH status information. A CSICH is always associated with a physical channel used for transmission of CPCH AP-AICH using the same channelization and scrambling codes. CSICH frame consists of 15 consecutive access slots (AS) each of length 40 bits. Each access slot consists of two parts, a part of duration 4096 chips with no transmission that is not formally part of the CSICH, and a Status Indicator (SI) part consisting of 8 bits b8i,â¦.b8i+7, where i is the access slot number. The part of the slot with no transmission is reserved for use by AICH, AP-AICH or CD/CA-ICH. The modulation used by the CSICH is the same as for the PICH. The phase reference for the CSICH is the Primary CPICH.
description: A fixed rate physical channel used to carry CPCH status information, always associated with a physical channel used for transmission of CPCH AP-AICH using the same channelization and scrambling codes.
explanation: The context explicitly describes CSICH as a physical channel, which justifies its classification as a Channel. The details provided about its structure, association with other channels, and modulation further support this categorization.
