Certain aspects of the present disclosure provide techniques for avoiding out of order uplink data reception upon data radio bearer (DRB) release or quality of service (QoS) flow addition. An exemplary method that may be performed by a user equipment (UE), includes receiving an indication from a base station (BS) that multiplexing of hybrid automatic retransmission request (HARQ) information and channel state information (CSI) is enabled in all physical uplink control channel (PUCCH) resources, generating a first CSI report regarding a first downlink (DL) channel from the BS, multiplexing a HARQ response to a transmission from the BS and the first CSI report in a PUCCH, and transmitting the PUCCH to the BS via one of the PUCCH resources.
