Abstract: Methods, systems, and devices for wireless communications are described. To reduce peak-to-average power ratio (PAPR) associated with transmissions in a wireless communications system, a user equipment (UE) may implement tone reservation techniques. The UE may receive downlink control information from a base station that indicates a set of allocated resources that the UE is to use for the tone reservation. The UE may identify a first set of tones of the set of allocated resources for transmitting a data signal and a second set of tones of the set of allocated resources for transmitting a peak-reduction signal that reduces the peak power of the data signal. The UE may transmit the data signal and the peak-reduction signal based on the received downlink control information.

Abstract: Methods, systems, and devices for wireless communications supporting techniques for enhanced line-of-sight (LOS) communications with analog multi-path beamforming are described. A first wireless device may receive, from a second wireless device, an indication of a capability of the second wireless device to concurrently transmit first signaling in a first analog beamforming direction using a first transmission configuration indicator (TCI) state corresponding to a LOS mode, and second signaling in a second analog beamforming direction using a second TCI state corresponding to an indirect LOS mode. The first wireless device may then receive, from the second wireless device, a first downlink message in the first analog beamforming direction using the first TCI state concurrently with a second downlink message in the second analog beamforming direction using the second TCI state.

Abstract: The present disclosure relates to dynamic antenna array reconfiguration and signaling in millimeter wave bands. A user equipment (UE) may detect an antenna array change condition. The UE may transmit a request for beam training for an antenna array configuration in response to the detecting. The request for beam training may include a requested antenna array configuration for the UE and an indication of beam weights to use with the requested antenna array configuration. A base station may determine whether to grant or deny the requested antenna array configuration for the UE. The UE may receive, from the base station, an indication of an antenna array configuration for the UE. The base station may transmit the number of reference signals as a set of contiguous channel state information reference signals (CSI-RS). The UE may train the reconfigured active antenna array configuration based on the reference signals.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support power headroom differential reporting for reference resource signals transmitted at different transmission power than other uplink transmissions. In a first aspect, a method of wireless communication includes determining a power headroom value, by a user equipment (UE), using a maximum configured transmission power and a transmission power configured for an uplink transmission at a configured modulation and coding scheme (MCS). The UE determines a reference resource signal power headroom value using the maximum configured transmission power and a reference resource signal transmission power configured for a reference resource signal transmission, calculates a reference resource power headroom differential between the power headroom value and the reference resource signal power headroom value, and transmits a report including the uplink transmission power headroom value and the reference resource power headroom differential. Other aspects and features are also claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may generate a signal for a set of synchronization signal blocks (SSBs) for an SSB burst set, wherein the set of SSBs are associated with a set of analog beamforming configurations associated with a set of spatial directions. The base station may transmit the signal for the set of SSBs using the set of analog beamforming configurations over the set of spatial directions. The base station may receive one or more random access channel (RACH) communications corresponding to one or more SSBs of the set of SSBs in accordance with one or more frequency domain beam sweeping configurations corresponding to one or more analog beamforming configurations of the set of analog beamforming configurations. Numerous other aspects are described.
