Samsung patents method for managing data reception during network bandwidth switches

1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising: receiving, from a base station, information for configuring hybrid automatic repeat request-acknowledgement (HARQ-ACK) feedback mode for a first semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH) configuration; identifying that a first bandwidth part (BWP) is deactivated and a second BWP is activated, wherein the first SPS PDSCH configuration is activated before the first BWP is deactivated and the second BWP is activated; when the first BWP is deactivated or the second BWP is activated, determining whether or not to process the first SPS PDSCH configuration based on the HARQ-ACK feedback mode; wherein the determining whether or not to process the first SPS PDSCH configuration based on the HARQ-ACK feedback mode includes: suspending or clearing the first SPS PDSCH configuration when the HARQ-ACK feedback mode is a first mode in which HARQ-ACK feedback is required; and performing reception of SPS PDSCHs based on the first SPS PDSCH configuration when the HARQ-ACK feedback mode is a second mode in which the HARQ-ACK feedback is not required, wherein the first BWP and the second BWP are uplink (UL) BWPs, wherein the UE is capable of transmitting ACK or negative acknowledgement (NACK) in the first mode, and wherein the UE is incapable of transmitting ACK or NACK in the second mode.
