    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling indicating a first set of thresholds corresponding to a first set of reference signal densities and a second set of thresholds corresponding to a second set of reference signal densities. The first set of thresholds may be associated with enabled uplink demodulation reference signal (DMRS) bundling, and the second set of thresholds may be associated with disabled uplink DMRS bundling. The UE may select a reference signal density from the first set or the second set based on a DMRS bundling status and map reference signaling (e.g., a DMRS, a phase tracking reference signal (PTRS), or both) to a set of resources based on the reference signal density. Uplink channel repetitions may occur in disjoint symbols and in such cases, DMRS bundling may be activated when PTRSs between repetitions meet a threshold.

    Abstract: This disclosure provides systems, methods, and devices for wireless communication that support reliability enhancements for implicit beam switching operations. In a first aspect, a method of wireless communication includes transmitting, by a wireless communication device, a channel state information (CSI) report using a first beam; monitoring, by the wireless communication device, for an implicit beam switch indication during a time window, the implicit beam switch indication corresponding to acceptance of Transmission Configuration Indicator (TCI) information indicated by the CSI report; and switching, by the wireless communication device, to a second beam from the first beam based on the implicit beam switch indication, the second beam different from the first beam. Other aspects and features are also claimed and described.

    Abstract: A wireless device (e.g., a UE or a base station) may identify a first subcarrier mapping associated with one or more redundant subcarriers. The one or more redundant subcarriers may correspond to one or more UWs in a UW-OFDM waveform. The wireless device may identify a second subcarrier mapping associated with one or more reference signals. A simultaneous application of the first subcarrier mapping and the second subcarrier mapping may be associated with one or more collisions. The wireless device may modify at least one of the first subcarrier mapping or the second subcarrier mapping to eliminate the one or more collisions. The wireless device may generate the UW-OFDM waveform based on the modified at least one of the first subcarrier mapping or the second subcarrier mapping. The wireless device may transmit a signal based on the generated UW-OFDM waveform.

    Abstract: A first network node may transmit an authentication proof to a second network node. The authentication proof may be based on a first credential associated with the first network node. The first network node may be authenticable based on the authentication proof. The second network node may identify whether the first network node is authentic based on the authentication proof. The second network node may transmit a configuration request to the first network node. The configuration request may include a phase-modulated indication of a second credential associated with the second network node. The configuration request may be based on a random phase. The second network node may be authenticable based on the configuration request. The first network node may transmit a configuration response to the second network node. The configuration response may include a phase-modulated confidential parameter. The configuration response may be based on the configuration request.
