name: RI
full_form: Rank Indicator
context: The minimum performance requirement in Table 9.9.4.1.2-2 is defined as a) The ratio of the throughput obtained when transmitting based on UE reported RI and that obtained when transmitting with fixed rank 1 shall be â¥ ï§ï±; b) The ratio of the throughput obtained when transmitting based on UE reported RI and that obtained when transmitting with fixed rank 2 shall be â¥ ï§ï²; For the parameters specified in Table 9.9.4.1.2-1, and using the downlink physical channels specified in Annex C.3.2, the minimum requirements are specified in Table 9.9.4.1.2-2. Table 9.9.4.1.2-1: RI Test (TDD) Table 9.9.4.1.2-2: Minimum requirement (TDD)
description: The Rank Indicator (RI) is a parameter used in the context of downlink physical channels to determine the minimum performance requirements for throughput when transmitting based on UE reported RI and fixed ranks. It plays a crucial role in ensuring that the user equipment (UE) meets specific standards for efficient data transmission, as outlined in Tables 9.9.4.1.2-1 and 9.9.4.1.2-2.
explanation: RI is classified as a Parameter because it serves as a configurable setting used to evaluate the performance of user equipment (UE) in terms of throughput, specifically in relation to rank-based transmission. This aligns with the 3GPP's focus on defining parameters that ensure optimal network and device performance.
