name: SCH
full_form: Synchronization Channel
context: SCH is a downlink signal used for cell search. SCH consists of two sub channels, the Primary and Secondary SCH. The 10 ms radio frames of the P- SCH are divided into 15 slots, each of length 2560 chips. P-SCH consists of a modulated code of length 256 chips, the Primary Synchronisation Code (PSC) denoted cp transmitted once every slot. The PSC is the same for every cell in the system. S-SCH consists of repeatedly transmitting a length 15 sequence of modulated codes of length 256 chips, the Secondary Synchronisation Codes (SSC), transmitted in parallel with the Primary SCH. The SSC is denoted csi,k in figure 18, where i = 0, 1, â¦, 63 is the number of the scrambling code group, and k = 0, 1, â¦, 14 is the slot number. Each SSC is chosen from a set of 16 different codes of length 256. This sequence on the Secondary SCH indicates which of the code groups the cell's downlink scrambling code belongs to. The primary and secondary synchronization codes are modulated by the symbol a, which
description: The Synchronization Channel (SCH) is a downlink signal used for cell search in FDD mode. It consists of two sub-channels: Primary SCH and Secondary SCH, which are used to transmit synchronization codes that help the UE identify the cell and its scrambling code group.
explanation: Based on the context provided from 3GPP TS 34.943, section 5, SCH is classified as a Connection because it refers to a specific downlink signal used for cell search, which involves communication between the network and user equipment (UE). The description of SCH's structure and function in transmitting synchronization codes further supports this classification.
