Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may include a first set of antenna arrays disposed in a first shape and a receiving device may include a second set of antenna arrays disposed in a second shape. A first axis that intersects an antenna array of the first set of antenna arrays and a centroid of the first shape may be offset from a vertical direction by a first angular offset. A second axis that intersects an antenna array of the second set of antenna arrays and a centroid of the second shape may be offset from the vertical direction by a second angular offset that is different than the first angular offset. The transmitting device may transmit signaling to the receiving device using the first and second sets of antenna arrays, respectively based on difference between the first and second angular offsets.

Abstract: An apparatus, at a network entity, for scheduling multi-user multiple-input multiple-output (MU-MIMO) transmissions to a co-scheduled set of user equipment (UEs) from an antenna array comprising multiple panels is disclosed. The apparatus comprises: a processor; a memory communicatively coupled to the processor; and executable instructions code stored in the memory, which when executed by the processor, cause the processor to: determine a reduced set of entries of panel-to-UE assignment from among multiple combinations of panel-to-UE assignment; and select, from within the reduced set, an entry of the panel-to-UE assignment for scheduling, based on a proportionately fair (PF) metric, wherein a panel-to-UE assignment is a mapping of the panels assigned to transmit to a selection of the UEs using associated serving beams configured for transmission to the respective UEs.

Abstract: A first wireless communication device may encode real samples of data to obtain encoded data based at least in part on adding one or more time domain complex samples to the real samples of the data. A function of the one or more time domain complex samples may be a known value, and the function may be a sum of exponentials of the one or more time domain complex samples. The first wireless communication device may transmit, to a second wireless communication device, the encoded data.

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: Methods, systems, and devices for wireless communication are described. An FNC may be implemented to manage operations of a wireless fronthaul network. The FNC may monitor one or more network conditions and parameters of a network, which may include a fronthaul network and a radio access network. The fronthaul network may include at least one DU that supports wireless communications with a plurality of RUs via a plurality of fronthaul communication links, and the radio access network may include the plurality of RUs supporting communications for a plurality of wireless devices. The FNC may output, based on the one or more network conditions and the parameters, one or more fronthaul operation parameters for the at least one DU to support wireless communication for at least one RU of the plurality of RUs via one or more respective communication links of the plurality of communication links.

Abstract: Methods, apparatuses, and computer-readable medium for fronthaul compression are provided. An example method may include receiving, from a UE, uplink data via one or more active tones of a plurality of tones in a symbol, the uplink data corresponding to an access vector. The example method may further include compressing the uplink data based on a linear transformation of a pseudo-access vector generated based on the access vector, the linear transformation including a matrix, the compression enabling a second network entity to decompress the compressed uplink data without knowing one or more locations associated with the one or more active tones. The example method may further include transmitting, to the second network entity, the compressed uplink data.
