Method and apparatus for determination of uplink/downlink transport block size and modulation and coding scheme

A method, comprising:

• transmitting configuration information including at least an indication of a configuration for
• a maximum transmission block size (TBS) for one of a physical uplink shared channel (PUSCH) transmission or a physical downlink shared channel (PDSCH) transmission, or
• a maximum modulation and coding scheme (MCS) for the one of the PUSCH transmission or the PDSCH transmission,
• wherein a TBS is determined based on at least the configured maximum TBS, and wherein one of
• a signal indicates whether the PUSCH or PDSCH transmission uses a default MCS,
• an MCS is determined based on at least the configured maximum MCS, or
• wherein the PUSCH is received or the PDSCH is transmitted based on the determined TBS and the determined MCS.

An apparatus, comprising:

• a transceiver configured to receive configuration information including at least an indication of a configuration for
• a maximum transmission block size (TBS) for one of a physical uplink shared channel (PUSCH) transmission or a physical downlink shared channel (PDSCH) transmission, or
• a maximum modulation and coding scheme (MCS) for the one of the PUSCH transmission or the PDSCH transmission;
• and
• a controller configured to
• determine a TBS based on at least the configured maximum TBS, and one of
• receive a signal indicating whether the PUSCH or PDSCH transmission uses a default MCS, or
• determine an MCS based on at least the configured maximum MCS,
• wherein the transceiver is configured to transmit the PUSCH or receive the PDSCH based on the determined TBS and the determined MCS.
