Abstract
Various solutions for dynamic and static cross-carrier physical uplink control channel (PUCCH) signaling and configuration in mobile communications are described. An apparatus, implementable in a UE, selects a component carrier (CC) from a plurality of CCs with a static approach or a dynamic approach. The UE then performs a PUCCH transmission to a network using the selected CC.
Claims18
A method, comprising:
- selecting, by a processor of an apparatus implemented in a user equipment (UE), a component carrier (CC) from a plurality of CCs;
- and
- performing, by the processor, a physical uplink control channel (PUCCH) transmission to a network using the selected CC,
- wherein the performing of the PUCCH transmission comprises:
- receiving downlink control information (DCI) from the network;
- and
- either:
- determining a size of a k1 bit-field in the DCI based on a largest list among a plurality of lists in a PUCCH group comprising the plurality of CCs;
- or
- padding the k1 bit-field in the DCI in an event that a shorter K1 list among the plurality of lists in the PUCCH group comprising the plurality of CCs is used.
