Abstract: Methods, systems, and devices for wireless communications are described. A user equipment, UE, may identify (305) that the UE is not connected with a first network to which the UE subscribes, and identify a fallback configuration (310).

The UE may attempt (320) to connect with the second network based on the fallback configuration and the UE not being connected with the first network. In some cases, a base station of a network may establish a connection with UEs based on receiving registration messages from the UEs in response to transmitting an indication that the network is available as a fallback network, identify a congestion level of the network and switch to a non-subscriber rejection mode in which the base station rejects connection with non-subscriber UEs.

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.
