Transmitting uplink control information associated with a small data transmission operation

A network node for wireless communication, comprising:

• one or more memories;
• and
• one or more processors coupled with the one or more memories and configured to cause the network node to:
• transmit, to a user equipment (UE), a first downlink communication associated with a small data transmission (SDT) operation, the first downlink communication indicating a dedicated physical uplink control channel (PUCCH) resource set;
• transmit a second downlink communication during the SDT operation, the second downlink communication comprising at least one of an SDT communication or a non-SDT communication, the non-SDT communication being transmitted during a radio resource control (RRC) inactive state associated with the UE or an RRC idle state associated with the UE;
• and
• receive, during the SDT operation and via the dedicated PUCCH resource set, uplink control information (UCI) associated with the second downlink communication, wherein the SDT operation comprises a mobile terminated (MT) SDT (MT-SDT) operation, and wherein to receive the UCI, the one or more processors are further configured to cause the network node to receive the UCI during the MT-SDT operation.

A method of wireless communication performed by a user equipment (UE), comprising:

• receiving a first downlink communication associated with a small data transmission (SDT) operation, the first downlink communication indicating a dedicated physical uplink control channel (PUCCH) resource set;
• receiving a second downlink communication during the SDT operation, the second downlink communication comprising at least one of an SDT communication or a non-SDT communication, the non-SDT communication being received during a radio resource control (RRC) inactive state associated with the UE or an RRC idle state associated with the UE;
• and
• transmitting, during the SDT operation and using the dedicated PUCCH resource set, uplink control information (UCI) associated with the second downlink communication, wherein the SDT operation comprises a mobile terminated (MT) SDT (MT-SDT) operation, and wherein transmitting the UCI comprises transmitting the UCI during the MT-SDT operation.
