name: PBCH
full_form: Physical Broadcast Channel
context: 8. Rel-16 introduces aggregation level 16 (only for MBMS dedicated cells) to enhance performance in low SINR conditions. - PBCH repetition: Similar to the scheme defined for eMTC (but with additional symbol-level rotation for interference randomization), PBCH is repeated in CAS.

description: The Physical Broadcast Channel (PBCH) is a critical component in Long-Term Evolution (LTE) and 5G terrestrial broadcast systems. It broadcasts essential system information to user equipment within the Evolved Universal Terrestrial Radio Access (E-UTRA) framework.
explanation: PBCH is classified as a Wireless Access Technology because it facilitates communication between base stations and user devices in wireless networks, specifically focusing on broadcasting system information crucial for device operation.
