A method for managing Hybrid Automatic Repeat Request (HARQ) feedback transmission by a Dual Sim Dual Standby (DSDS) User Equipment (UE) in a wireless communication network, is provided. The method includes determining, by the DSDS UE, whether a first parameter associated with a primary packet data is identical to a second parameter associated with a secondary packet data. Each of the first parameter and the second parameter comprises a reordering timer value, a New Data Indicator (NDI), a HARQ process number, and a DSDS Radio Frequency (RF) gap duration. The method further includes, in response to the first parameter associated with the primary packet data being determined to be identical to the second parameter associated with the secondary packet data and the primary packet data being successfully decoded at the DSDS UE, performing, by the DSDS UE, the HARQ feedback transmission with the wireless communication network.
