Method and apparatus for transmitting a HARQ-ACK

A base station for wireless communication, comprising:

• at least one memory;
• and
• at least one processor coupled with the at least one memory and configured to cause the base station to:
• determine one or more allocated resource blocks for a first physical uplink channel based on an indicated sub-band group and one or more resource block groups within the indicated sub-band group,
• wherein the sub-band group includes one or more sub-bands, each sub-band comprises one or more resource block groups, each resource block group comprises one or more resource blocks, and a resource block includes one or more contiguous resource elements in a frequency domain;
• transmit, to a user equipment (UE), scheduling information that schedules the UE to transmit the first physical uplink channel within a slot, wherein the slot includes a plurality of symbols,
• wherein the scheduling information indicates the indicated sub-band group and the one or more resource block groups within the indicated sub-band group;
• and
• receive the first physical uplink channel in the one or more allocated resource blocks in the slot,
• wherein the scheduling information includes a sub-band group index and a resource block group bitmap, and
• wherein each bit in the resource block group bitmap corresponds to each resource block group within the indicated sub-band group and indicates a resource assignment of the corresponding resource block group.

A user equipment (UE) for wireless communication, comprising:

• at least one memory;
• and
• at least one processor coupled with the at least one memory and configured to cause the UE to:
• receive scheduling information that schedules the UE to transmit a first physical uplink channel within a slot, wherein the slot includes a plurality of symbols, wherein the scheduling information indicates a sub-band group and one or more resource block groups within the sub-band group;
• determine one or more allocated resource blocks for the first physical uplink channel based on the sub-band group and the one or more resource block groups within the sub-band group, wherein the sub-band group includes one or more sub-bands, each sub-band comprises one or more resource block groups, each resource block group comprises one or more resource blocks, and a resource block includes one or more contiguous resource elements in a frequency domain;
• and
• transmit the first physical uplink channel in the one or more allocated resource blocks in the slot,
• wherein the scheduling information includes a sub-band group index and a resource block group bitmap, and
• wherein each bit in the resource block group bitmap corresponds to each resource block group within the indicated sub-band group and indicates a resource assignment of the corresponding resource block group.

A method performed by a user equipment (UE), the method comprising:

• receiving scheduling information that schedules the UE to transmit a first physical uplink channel within a slot, wherein the slot includes a plurality of symbols, wherein the scheduling information indicates a sub-band group and one or more resource block groups within the sub-band group;
• determining one or more allocated resource blocks for the first physical uplink channel based on the sub-band group and the one or more resource block groups within the sub-band group, wherein the sub-band group includes one or more sub-bands, each sub-band comprises one or more resource block groups, each resource block group comprises one or more resource blocks, and a resource block includes one or more contiguous resource elements in a frequency domain;
• and
• transmitting the first physical uplink channel in the one or more allocated resource blocks in the slot,
• wherein the scheduling information includes a sub-band group index and a resource block group bitmap, and
• wherein each bit in the resource block group bitmap corresponds to each resource block group within the indicated sub-band group and indicates a resource assignment of the corresponding resource block group.
