name: RACH
full_form: Random Access Channel
context: The setting of RACH parameters that can be optimized are: - RACH configuration (resource unit allocation); - RACH preamble split (among dedicated, group A, group B); - RACH backoff parameter value; - RACH transmission power control parameters. As a minimum, RACH optimization is realized by UE providing RACH related information report to the NG RAN node, and by exchange of PRACH configuration of normal UL carrier and SUL carrier between NG RAN node. For CU-DU architecture, gNB-DU should be allowed to report its RACH configuration per cell to the gNB-CU, and the gNB-CU should be allowed to signal the RACH configuration per served cell to neighbouring NG RAN nodes. This allows NG-RAN nodes to identify whether RACH configurations of neighbouring cells are optimized or whether changes are needed in order to achieve a better RACH coordination between neighbouring cells. Upon receiving the polling message requesting RACH report, e.g. UE Information Request message, from the NG RAN node
description: The Random Access Channel (RACH) is a critical uplink channel in cellular networks used for initial access and handover procedures. It allows user equipment to request resources from the base station for data transmission. The RACH parameters, such as configuration, preamble split, backoff parameter value, and transmission power control parameters, can be optimized to improve network performance.
explanation: RACH is classified as a Channel based on its role in facilitating random access from user equipment to the network, as described in the context. The discussion around RACH optimization, configuration, and reporting further solidifies its classification as a channel within the network architecture.
