name: PMI
full_form: Precoding Matrix Indicator
context: For the parameters specified in Table 9.4.1.1.2-1, and using the downlink physical channels specified in Annex C.3.2, the minimum requirements are specified in 9.4.1.1.2-2. Table 9.4.1.1.2-1: PMI test for single-layer (TDD) Table 9.4.1.1.2-2: Minimum requirement (TDD)
description: The Precoding Matrix Indicator (PMI) is a parameter used in the context of downlink physical channels, specifically for single-layer transmissions in Time Division Duplexing (TDD) mode. It is utilized to indicate the precoding matrix used for transmitting data, which is crucial for ensuring efficient and reliable communication over the wireless channel. The PMI is subject to minimum requirements as specified in 3GPP standards, such as those outlined in Table 9.4.1.1.2-1 and Table 9.4.1.1.2-2, to guarantee optimal performance under various conditions.
explanation: PMI is classified as a Parameter because it represents a specific value or setting used within the context of downlink physical channels in TDD mode. Its primary function is to indicate the precoding matrix, which directly affects how data is transmitted and received, thus fitting into the category of parameters that are crucial for the operation and optimization of telecommunication systems as defined by 3GPP specifications.
