Abstract
Method and apparatus are provided for decoding a downlink control information (DCI) format that schedules a physical uplink shared channel (PUSCH) transmission and includes a field indicating whether or not data information is multiplexed in the PUSCH and for transmitting the PUSCH with or without data information depending on the indication by the field.
Claims20
A method comprising:
- receiving a physical downlink shared channel (PDSCH) that provides a transport block (TB), wherein the PDSCH reception is scheduled by a first downlink control information (DCI) format;
- identifying that a physical uplink control channel (PUCCH) transmission including acknowledgement information for the TB would overlap in time with a first physical uplink shared channel (PUSCH) transmission;
- multiplexing the acknowledgment information for the TB in the first PUSCH based on determining that a start time for transmission of the first PUSCH is after an end time of the PDSCH reception by at least a predetermined time;
- and
- transmitting the first PUSCH.
2 more elements
A user apparatus (UE) comprising:
- a transceiver configured to receive a physical downlink shared channel (PDSCH) that provides a transport block (TB), wherein the PDSCH reception is scheduled by a first downlink control information (DCI) format;
- and
- a processor configured to:
- identify that a physical uplink control channel (PUCCH) transmission including acknowledgement information for the TB would overlap in time with a first physical uplink shared channel (PUSCH) transmission;
- and
- multiplex the acknowledgment information in the first PUSCH based on a determination that a start time for transmission of the first PUSCH is after an end time of the PDSCH reception by at least a predetermined time,
- wherein the transceiver is further configured to transmit the first PUSCH.

A base station comprising:
- a transceiver configured to transmit a physical downlink shared channel (PDSCH) that provides a transport block (TB), wherein the PDSCH transmission is scheduled by a first downlink control information (DCI) format;
- and
- a processor configured to:
- identify that a physical uplink control channel (PUCCH) reception for inclusion of acknowledgement information for the TB would overlap in time with a first physical uplink shared channel (PUSCH) reception;
- and
- determine that the acknowledgment information is multiplexed in the first PUSCH based on a determination that a start time for reception of the first PUSCH is after an end time of the PDSCH transmission by at least a predetermined time,
- wherein the transceiver configured to receive the first PUSCH.
