Uplink control information transmission format selection

A network node for selection of uplink control information (UCI) transmission format, comprising:

• a memory;
• a communication interface;
• and
• at least one processor communicatively coupled to the memory and the communication interface, the at least one processor configured to:
• determine whether to use a coherent transmission;
• upon determining to use a coherent transmission, selecting a coherent transmission format for UCI transmission as a selected format for UCI transmission;
• upon determining not to use a coherent transmission:
• determining whether to use an orthogonal sequence based on a size of an assigned resource and a size of UCI payload;
• upon determining to use an orthogonal sequence, selecting a non-coherent transmission format with an orthogonal sequence for UCI transmission as the selected format for UCI transmission;
• and
• upon determining not to use an orthogonal sequence, selecting a non-coherent transmission format with a non-orthogonal sequence for UCI transmission as the selected format for UCI transmission;
• and
• use the selected format for UCI transmission.

A network node for selection of uplink control information (UCI) transmission format, comprising:

• means for determining whether to use a coherent transmission;
• means for selecting, upon determining to use a coherent transmission, a coherent transmission format for UCI transmission as a selected format for UCI transmission;
• means for determining, upon determining not to use a coherent transmission, whether to use an orthogonal sequence based on a size of an assigned resource and a size of UCI payload;
• means for selecting, upon determining to use an orthogonal sequence, a non-coherent transmission format with an orthogonal sequence for UCI transmission as the selected format for UCI transmission;
• means for selecting, upon determining not to use an orthogonal sequence, a non-coherent transmission format with a non-orthogonal sequence for UCI transmission as the selected format for UCI transmission;
• and
• means for using the selected format for UCI transmission.

A non-transitory computer-readable medium storing computer-executable instructions that, when executed by a network node for selection of uplink control information (UCI) transmission format, cause the network node to:

• determine whether to use a coherent transmission;
• upon determining to use a coherent transmission, select a coherent transmission format for UCI transmission as a selected format for UCI transmission;
• upon determining not to use a coherent transmission:
• determine whether to use an orthogonal sequence based on a size of an assigned resource and a size of UCI payload;
• upon determining to use an orthogonal sequence, select a non-coherent transmission format with an orthogonal sequence for UCI transmission as the selected format for UCI transmission;
• and
• upon determining not to use an orthogonal sequence, select a non-coherent transmission format with a non-orthogonal sequence for UCI transmission as the selected format for UCI transmission;
• and
• use the selected format for UCI transmission.
