In some aspects, a first user equipment (UE) may communicate an inter-UE coordination (IUC) message with a second UE, the IUC message comprising first beam maintenance reference signal (BM RS) information. The UE may transmit a BM RS using, based on the first BM RS information, a set of BM RS resources. Numerous other aspects are described. ## Claims ### Claim 1 A first user equipment (UE) for wireless communication, comprising: one or more memories; and one or more processors, coupled to the one or more memories, configured to cause the first UE to: communicate an inter-UE coordination (IUC) message with a second UE, the IUC message comprising first beam maintenance reference signal (BM RS) information;
