Power headroom report for LTE-NR co-existence

Abstract:

Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for a power headroom report for multiple radio access technologies (RATs). A user equipment (UE) may support multiple RATs that correspond to different transmission time intervals (TTIs). A UE may determine a reporting schedule for power headroom reports (PHRs) for a first RAT and a second schedule for PHRs for a second RAT. The UE may generate a PHR for the first RAT and a companion PHR for the second RAT, and may transmit the PHR and companion PHR based at least in part on the first PHR schedule. In some examples, the UE may receive a PHR type from the base station, and may determine a joint PHR based on the type. The UE may determine a joint PHR schedule based on a granularity of supported RATs.
