name: PTI
full_form: Precoding Type Indicator
context: stop the timer T3582. The UE should ensure that the PTI value assigned to this procedure is not released immediately. NOTE 1: The way to achieve this is implementation dependent. For example, the UE can ensure that the PTI value assigned to this procedure is not released during the time equal to or greater than the default value of timer T3592. While the PTI value is not released, the UE regards any received PDU SESSION RELEASE COMMAND message with the same PTI value as a network retransmission (see subclause 7.3.1). If the PDU SESSION RELEASE COMMAND message includes 5GSM cause #39 "reactivation requested", then after completion of the network-requested PDU session release procedure, the UE should re-initiate the UE-requested PDU session establishment procedure as specified in subclause 6.4.1 for: a) the PDU session type associated with the released PDU session; b) the SSC mode associated with the released PDU session; c) the DNN associated with the released PDU session; and d) the
description: The Precoding Type Indicator (PTI) is a parameter used in the context of network-requested PDU session release and reactivation procedures. It is utilized to ensure that the UE does not release the PTI value immediately, allowing for potential retransmissions or re-initiation of PDU session establishment procedures.
explanation: The provided description explicitly states that PTI is a parameter used within specific network procedures. Its function is to control and manage aspects of PDU sessions, making it a key attribute in these processes.
