Abstract: A user equipment (UE) may increase the reliability of transmission of a Physical Uplink Control Channel (PUCCH) by transmitting repeated copies of the PUCCH, according to a repetition pattern spanning one or more slots. In an intra-slot mode, more than one copy may be transmitted within each configured slot, with or without frequency hopping. The number of copies as well as a temporal gap between the transmission of successive copies may be configured by the network. The repetition pattern may or may not be interrupted by slot boundaries. In an inter-slot mode, one copy is transmitted per configured slot. Different copies may be transmitted in different directions, according to a spatial consistency pattern. The UE may perform repeated transmission of PUCCHs to different Transmission-Reception Points (TRPs) using respectively different timing advances and/or transmit power levels.

Abstract: Methods, systems, and devices for wireless communications are described. To monitor a PDCCH for CA, a UE may receive PDCCH candidates in a plurality of configured component carriers (CCs). In response to a determination that a maximum number of virtual CCs that the UE is capable of monitoring for PDCCH is smaller than a number of the plurality of configured CCs, the UE groups the plurality of configured CCs into CC groups based at least in part on SCS numerologies and PDCCH monitoring configurations corresponding to span patterns within a slot of a DL subframe. The UE determines a maximum number of blind decoding operations and non-overlapped CCEs for each of the CC groups. The UE then monitors at least a first portion of the PDCCH candidates based on the maximum number of blind decoding operations and non-overlapped CCEs for each of the CC groups.
