name: PSFCH
full_form: Physical Sidelink Feedback Channel
context: UE determines from the PSFCH reception - if the UE receives a PSFCH associated with a SCI format 2-A with Cast type indicator field value of "01" - report an ACK value to higher layers if the UE determines an ACK value from at least one PSFCH reception occasion from the number of PSFCH reception occasions in PSFCH resources corresponding to every identity of UEs that the UE expects to receive corresponding PSSCHs as described in clause 16.3; otherwise, report a NACK value to higher layers - if the PSFCH reception occasion is associated with a SCI format 2-B or a SCI format 2-A with Cast type indicator field value of "11" - report to higher layers an ACK value if the UE determines absence of PSFCH reception for the PSFCH reception occasion; otherwise, report a NACK value to higher layers A UE that transmitted SCI format 1-A, indicating one or more reserved resources in a resource pool enabled by sl-InterUE-CoordinationScheme2, attempts to receive associated PSFCH with conflict
description: The Physical Sidelink Feedback Channel (PSFCH) is a channel used for transmitting feedback information in sidelink communications. It is utilized by the UE to report ACK or NACK values based on the reception of PSFCH associated with different SCI formats and cast type indicators.
explanation: PSFCH is classified as a Connection entity, specifically a Channel, due to its role in carrying feedback information between network endpoints in sidelink communications. The context highlights its usage in UE procedures for receiving and reporting ACK/NACK values based on PSFCH receptions.
