A system can include a network analysis platform that applies models to identify downlink interference at a network cell, such as at a base station. For a session at a cell, an expected performance with normalized downlink interference can be compared to an actual performance to determine whether the session is impacted.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a control channel message encoded according to a first format that is associated with a different set of shared data channel parameters than a second format supported by the UE. The second format is a legacy format relative to the first format. The UE may further determine that the control channel message is encoded according to the first format based at least in part on comparing one or more bit values, of the control channel message, in bit positions corresponding to a set of bits defined by the second format, and one or more expected bit values defined by the first format. The UE may select one or more resources for transmission based at least in part on information included in the control channel message. Numerous other aspects are provided.
