Abstract: Systems, methods, apparatuses, and computer program products for intelligent reflecting surface configuration. The method may include scanning for synchronization signal blocks and reflection surface synchronization signal blocks during a cell search at a frequency on a synchronization raster. The method may also include determining whether a synchronization signal block or a reflection surface synchronization signal block is detected as a result of the scanning. The method may further include selecting a detected synchronization signal block or a detected reflection synchronization signal block based on a measurement metric of the detected synchronization signal block and the detected reflection synchronization signal block. In addition, the method may include performing an access procedure with a network element using the selected synchronization signal block or the selected reflection synchronization signal block.

Abstract: Systems, methods, apparatuses, and computer program products for initialization and operation of intelligent reflecting surface. The method may include transmitting a synchronization signal block burst to a reflection surface device. The method may also include receiving a first measurement report of the synchronization signal block burst received at the reflection surface device. The method may further include determining a transmit beam for a subsequent synchronization signal block burst based on a highest strength of signals in the synchronization signal block burst. In addition, the method may include receiving a second measurement report of the subsequent synchronization signal block burst. Further, the method may include determining an arrival angle of the subsequent synchronization signal block burst at the reflection surface device. The method may also include establishing a connection with the reflection surface device based on the transmit beam and the arrival angle.

Abstract: Various communication system may benefit from the appropriate selection of communication parameters. For example, certain wireless communication systems may benefit from the user of a low-overhead high-rank codebook. A method can include determining a first partition of a precoding matrix with a higher resolution and a second partition of the precoding matrix with a lower resolution. The method can also include feeding back the first partition and the second partition.

Abstract: Various communication systems may benefit from new slot formats to support dynamic allocation between SC and CP-OFDMA. In accordance with some embodiments, a method may include transmitting, by a network entity, at least one physical downlink slot containing at least one physical downlink shared channel (PDSCH) and at least one physical downlink control channel (PDCCH). The at least one PDCCH is associated with at least one subcarrier waveform without a cyclic prefix (CP). The at least one PDSCH is associated with at least one CP-orthogonal frequency division multiplexing (OFDM) or single carrier (SC) waveform.

Abstract: Dynamic and partial sharing of the channel measurement downlink reference signal resources are provided. An apparatus performs determining information relating to an actual number of ports configured for a user equipment for channel measurements and determining a pool of channel state information reference signal resources for the user equipment. The pool of channel state information reference signal resources is provided in a radio resource control configuration and includes an excess number of ports compared to the actual number of ports. The apparatus also transmits to the user equipment via at least one of a medium access control control element or downlink control information, configured user equipment specific mapping for the pool of channel state information reference signal resources.
