US 12,756,506 B2 · Methods of collision resolution between multiple high priority PUCCHs with HARQ-ACK and a low priority PUSCH

Abstract

A user equipment (UE) is described. The UE includes circuitry configured to determine that a physical uplink control channel (PUCCH) with high priority (HP) carrying HP hybrid automatic repeat request-acknowledgements (HARQ-ACKs) overlaps with a physical uplink shared channel (PUSCH) with low priority (LP). When only one HP PUCCH with HP HARQ-ACK overlaps with a LP PUSCH, multiplex the HP HARQ-ACK on the LP PUSCH starting from an orthogonal frequency-division multiplexing (OFDM) symbol that is available after a first consecutive demodulation reference signal (DM-RS) OFDM symbol. When more than one HP PUCCH with HP HARQ-ACK overlaps with a LP PUSCH, for each overlapping HP PUCCH carrying the HP HARQ-ACK, multiplex a corresponding HP HARQ-ACK on confined symbols of the LP PUSCH.

A user equipment (UE), comprising:

circuitry configured to:
determine that a physical uplink control channel (PUCCH) with high priority (HP) carrying HP hybrid automatic repeat request-acknowledgements (HARQ-ACKs) overlaps with a physical uplink shared channel (PUSCH) with low priority (LP);
when overlapping with only one HP PUCCH with HP HARQ-ACK is known before an LP PUSCH transmission, multiplex a first HP HARQ-ACK from a first overlapping HP PUCCH on the LP PUSCH and transmit later overlapping HP PUCCH(s) carrying the HP HARQ-ACK by partially dropping the LP PUSCH with the first HP HARQ-ACK perform channel dropping for later overlapping HP PUCCH with HP HARQ-ACK;
and
when overlapping with more than one HP PUCCH with HP HARQ-ACK is known before an LP PUSCH transmission, cancel the LP PUSCH and transmit HP PUCCHs with HP HARQ-ACKs.
