Switching between different configurations of frequency and beam hopping for single-beam and multi-beam PUCCH

A method of wireless communication of a user equipment (UE), comprising:

• receiving a physical uplink control channel (PUCCH) resource information element (IE) for a PUCCH resource indicating a PUCCH resource intra-slot frequency hopping configuration;
• determining whether multiple PUCCH beams are activated for the PUCCH resource;
• determining a mode for frequency hopping and beam hopping for the PUCCH resource based on at least one of the PUCCH resource intra-slot frequency hopping configuration, or a determination whether the multiple PUCCH beams are activated;
• and
• transmitting on the PUCCH resource based on a determined mode.

An apparatus for wireless communication, the apparatus being a user equipment (UE), comprising:

• means for receiving a physical uplink control channel (PUCCH) resource information element (IE) for a PUCCH resource indicating a PUCCH resource intra-slot frequency hopping configuration;
• means for determining whether multiple PUCCH beams are activated for the PUCCH resource;
• means for determining a mode for frequency hopping and beam hopping for the PUCCH resource based on at least one of the PUCCH resource intra-slot frequency hopping configuration, or a determination whether the multiple PUCCH beams are activated;
• and
• means for transmitting on the PUCCH resource based on a determined mode.

A non-transitory computer-readable medium storing computer executable code, the code when executed by a processor at a user equipment (UE) causes the processor to:

• receive a physical uplink control channel (PUCCH) resource information element (IE) for a PUCCH resource indicating a PUCCH resource intra-slot frequency hopping configuration;
• determine whether multiple PUCCH beams are activated for the PUCCH resource;
• determine a mode for frequency hopping and beam hopping for the PUCCH resource based on at least one of the PUCCH resource intra-slot frequency hopping configuration, or a determination whether the multiple PUCCH beams are activated;
• and
• transmit on the PUCCH resource based on a determined mode.
