name: TFI
full_form: Transport Format Indicator
context: Description: When the Node B receives a HS-DSCH DATA FRAME where the 1-bit FSN/DRT Reset IE is set to 1, the Node B should reset any state of congestion estimation based on previously received FSN and DRT values. Node B may instead decide to start a new estimation of congestion detection initiated with the FSN and DRT values included in this HS-DSCH data frame. FSN/DRT Reset IE set to 1 may indicate a discontinuity in the sequence of the transmitted DRT and FSN values in the transmitted HS-DSCH data frames belonging to the associated MAC-d flow. If the 1-bit FSN/DRT Reset IE is set to 0, Node B may use the included DRT and FSN values for congestion detection. Value range: 0 Node B may use the included DRT and FSN values for congestion detection. 1 Node B should not use previously received FSN and DRT values for congestion detection. Field length: 1 bit.
description: The Transport Format Indicator (TFI) is a parameter used in downlink transmission. It specifies the format of the transport block, including its length and the number of transport blocks. A TFI value of zero bits or a number of transport blocks equal to zero indicates whether data is being transmitted within a specific Transmission Time Interval (TTI).
explanation: The text explicitly refers to TFI as a 'parameter' used in the downlink transmission process. It describes how TFI influences the structure and content of data transmission, making it a parameter rather than a broader telecommunications concept.
