Downlink control indicator (DCI) monitoring and semi-persistent scheduling (SPS) reception with limited capability devices

A method of wireless communication performed by a base station, the method comprising:

• transmitting, to a user equipment, a semi-persistent scheduling (SPS) grant, the SPS grant indicating a periodicity and at least a first SPS resource, the first SPS resource associated with a first physical uplink control channel (PUCCH) resource in a second slot;
• transmitting, in a first slot scheduled fora downlink data communication for the user equipment and prior to an end of a last symbol of the downlink data communication in the first slot, an SPS release, wherein the downlink data communication is scheduled in a first SPS resource in the first slot, wherein the first physical uplink control channel (PUCCH) resource in the second slot is scheduled for receiving a first hybrid automatic repeat request acknowledgement (HARQ-ACK) for the downlink data communication in the first slot;
• and
• receiving, from the user equipment in the first PUCCH resource scheduled for receiving the first HARQ-ACK for the downlink data communication, and instead of the first HARQ-ACK for the downlink data communication, a second HARQ-ACK for the SPS release,
• wherein the receiving the second HARQ-ACK for the SPS release is based on the user equipment receiving the SPS release prior to the end of the last symbol of the downlink data communication in the first slot, and the user equipment refraining from decoding the downlink data communication in the first slot, and the user equipment refraining from transmitting the first HARQ-ACK for the downlink data communication in the first PUCCH resource in the second slot.

A user equipment, comprising:

• a transceiver configured to:
• receive, from a base station, a semi-persistent scheduling (SPS) grant, the SPS grant indicating a periodicity;
• and
• a processor in communication with the transceiver, the processor configured to:
• monitor, in a first slot scheduled for a downlink data communication, for an SPS release and the downlink data communication, wherein the downlink data communication is scheduled in a first SPS resource in the first slot, wherein a first physical uplink control channel (PUCCH) resource in a second slot is scheduled to provide a first hybrid automatic repeat request acknowledgement (HARQ-ACK) for the downlink data communication, and wherein the monitoring comprises receiving the SPS release prior to an end of a last symbol of the downlink data communication in the first slot;
• wherein the transceiver is further configured to:
• refrain, based on receiving the SPS release prior to the end of the last symbol of the downlink data communication in the first slot:
• from decoding the downlink data communication in the first slot;
• and
• from transmitting the first HARQ-ACK for the downlink data communication in the first PUCCH resource in the second slot;
• and
• transmit, to the base station in the first PUCCH resource scheduled to provide the first HARQ-ACK for the downlink data communication, and instead of the first HARQ-ACK for the downlink data communication, a second HARQ-ACK for the SPS release, wherein the transmitting the second HARQ-ACK is based on the receiving the SPS release prior to the end of the last symbol of the downlink data communication.

A base station, comprising:

• a processor;
• and
• a transceiver in communication with the processor, the transceiver configured to:
• transmit, to a user equipment, a semi-persistent scheduling (SPS) grant, the SPS grant indicating a periodicity and at least a first SPS resource, the first SPS resource associated with a first physical uplink control channel (PUCCH) resource in a second slot;
• transmit, in a first slot scheduled for a downlink data communication for the user equipment and prior to an end of a last symbol of the downlink data communication in the first slot, an SPS release, wherein the downlink data communication is scheduled in a first SPS resource in the first slot, wherein the first physical uplink control channel (PUCCH) resource in the second slot is scheduled for receiving a first hybrid automatic repeat request acknowledgement (HARQ-ACK) for the downlink data communication in the first slot;
• and
• receive, from the user equipment in the first PUCCH resource scheduled for receiving the first HARQ-ACK for the downlink data communication, and instead of the first HARQ-ACK for the downlink data communication, a second HARQ-ACK for the SPS release,
• wherein to receive the second HARQ-ACK for the SPS release is based on the user equipment receiving the SPS release prior to the end of the last symbol of the downlink data communication in the first slot, and the user equipment ref refraining from decoding the downlink data communication in the first slot, and the user equipment refraining from transmitting the first HARQ-ACK for the downlink data communication in the first PUCCH resource in the second slot.
