Abstract: Methods, systems, and devices for wireless communications are described. A communication device, which may be otherwise known as user equipment (UE) may support repetition of physical downlink control channels (PDCCH) and handling a combined PDCCH candidate associated with multiple search space sets. For example, a UE may combine a first PDCCH candidate corresponding to a first search space set and a second PDCCH candidate corresponding to a second search space set to form a combined PDCCH candidate. The UE may decode the combined PDCCH candidate based on one or more factors, for example, such as a blind decoding PDCCH candidate threshold. As a result, the UE may decode the combined PDCCH candidate in addition to decoding of individual PDCCH candidates, thereby providing increased flexibility for downlink control information (DCI) and improving the reliability of PDCCH.

Abstract: Methods, systems, and devices for wireless communication are described to indicate a transmission scheme configuration for a message and whether the message is a retransmission or new transmission. In a first example, a base station may configure a subset of one or more feedback process identifiers (IDs) for multicast messages. In such cases, if a grant includes a feedback process ID associated with one of the reserved IDs, the message scheduled by the grant may be a retransmission of a multicast message. In a second example, feedback process IDs may be dynamically allocated to multicast or unicast messages via a corresponding grant. A message may be identified as a new transmission or retransmission of a unicast message or multicast message based on a combination of an ID associated with the grant and a new data indicator (NDI) of the grant.

For example, in a multi-TRP scenario that includes two TRPs, the UE may eliminate overlap of these uplink channels for each of the two TRPs individually and may additionally eliminate overlap of these uplink channels between the two TRPs.
