name: TA
full_form: Terminal Adapter
context: applies the TA value measured by itself and performs RACH-less LTM upon receiving the cell switch command. The network may also send a TA value in the LTM cell switch command MAC CE without early TA acquisition. Depending on the availability of a valid TA value, the UE performs either a RACH-less LTM or RACH-based LTM cell switch. If the TA value is provided in the cell switch command, the UE applies the TA value as instructed by the network. In the case where UE-based TA measurement is configured, but no TA value is provided in the cell switch command, the UE applies the TA value by itself if available. Meanwhile, the UE performs RACH-less LTM cell switch upon receiving the cell switch command. If no valid TA value is available, the UE performs RACH-based LTM cell switch. Regardless of whether the UE is configured for UE-based TA measurement for a certain candidate cell, it will still follow the PDCCH order, which includes requesting a random access procedure towards the candidate
description: TA (Terminal Adapter) is a critical network attribute used in Random Access Channel (RACH) procedures and cell switching in LTE networks. It influences the timing advance applied by the User Equipment (UE) during the random access process, ensuring proper synchronization with the base station.
explanation: The text describes TA as a parameter that affects the UE's transmission timing during cell switch procedures. This role in network operation and performance directly classifies it as a parameter.
