name: AA
full_form: Antenna Array
context: Idle mode is initiated by the UE, the UE shall considered the physical channel being immediately established. If the physical layer considers the post-verification of procedure AA failed [29, section 4.3.2.3A], the UE shall consider this as a "physical channel failure". NOTE: The criteria defined in this subclause only apply in case the UE performs synchronisation procedure AA (FDD only). [â¦] d) The UE shall start transmission on uplink at the time defined for the Enhanced Uplink in CELL_FACH state and IDLE mode in [1] and shall use a post-verification period for confirming the establishment of the downlink physical channel as follows: During the first 40 ms period of the first phase of the downlink synchronisation procedure the UE shall control its transmitter according to a downlink F-DPCH quality criterion as follows: - When the UE estimates the F-DPCH quality over the first 40 ms period of the first phase of the downlink synchronisation status evaluation to be worse than a
description: Antenna Array (AA) refers to a technology used in telecommunications for improving signal reception and transmission. In the context provided, it is related to the physical channel failure procedure during initial access preamble in CELL-FACH state.
explanation: The classification of AA as Technology is based on its role in enhancing signal quality and its mention in relation to specific procedures (post-verification of procedure AA) and criteria for physical channel establishment. This indicates that AA is a technological aspect rather than a protocol, network function, or any other predefined category.
