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 control channel (PDCCH) that provides a first downlink control information (DCI) format;
- decoding the first DCI format, wherein the first DCI format:
- schedules a physical uplink shared channel (PUSCH) transmission, and
- includes a first field indicating whether or not uplink shared channel (UL-SCH) information is multiplexed in the PUSCH;
- determining to multiplex or not multiplex UL-SCH information in the PUSCH depending on the indication in the first field;
- and
- transmitting the PUSCH based on the determination.
4 more elements
A user equipment (UE) comprising:
- a receiver configured to receive a physical downlink control channel (PDCCH) that provides a first downlink control information (DCI) format;
- a decoder configured to decode the first DCI format, wherein the first DCI format:
- schedules a physical uplink shared channel (PUSCH) transmission, and
- includes a first field indicating whether or not uplink shared channel (UL-SCH) information is multiplexed in the PUSCH;
- a multiplexer configured to multiplex or not multiplex UL-SCH information in the PUSCH depending on the indication in the first field;
- and
- a transmitter configured to transmit the PUSCH.
4 more elements
A base station comprising:
- an encoder configured to encode a first downlink control information (DCI) format, wherein the first DCI format:
- schedules a physical uplink shared channel (PUSCH) transmission, and
- includes a first field indicating whether or not uplink shared channel (UL-SCH) information is multiplexed in the PUSCH;
- a transmitter configured to transmit a physical downlink control channel (PDCCH) with the first DCI format;
- a receiver configured to receive the PUSCH;
- and
- a de-multiplexer configured to de-multiplex or not de-multiplex UL-SCH information in the PUSCH depending on the indication in the first field.
