Abstract: The present disclosure relates generally to the field of wireless communications and, in particular, to techniques for spatially quantizing a spherical coverage of a user equipment (UE) and using the spatially quantized spherical coverage in beamforming at the UE and a network node in a wireless communication system. To this end, the UE transmits, to the network node, location information of the UE and antenna parameter measurements which are taken at least one time in at least one spatial section of the spatially quantized spherical coverage. The network node obtains a signal model based on the UE location information and the antenna parameter measurements. The signal model may be obtained by using a data processing algorithm, e.g., a machine learning algorithm. The signal model is indicative of how reference signals are to be transmitted from the network node to the UE. By so doing, it is possible to optimize the transmission of the reference signals from the network node to the UE, since the network node knows which of the spatial sectors of the spatially quantized spherical coverage of the UE is most suitable for their reception.

Abstract: Aspects of the disclosure relate to beam sweeping with controllable reflective surfaces in the presence of co-located base stations of different network operators. A first base station that is co-located at a site with a second base station may perform a first beam sweep. The first beam sweep includes transmitting a plurality of directional beams. The first base station further transmits a control signal to a controllable reflective surface to control the controllable reflective surface to reduce a likelihood of a redirection of a directional beam of a potential second beam sweep by the second base station towards a user equipment associated with the second base station. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a failure to decode scheduled downlink transmissions directed to the UE on a first beam. The UE may determine whether the failure is due to the first beam being beam blocked. If the failure is due to beam blocking, the UE may transmit, to the base station, a beam blocking detection scheduling request that may request a set of uplink resources for the UE to transmit a channel state information (CSI) report including the beam blocking detection information. The UE may transmit the beam blocking detection scheduling request on a set of uplink beams. The UE may be configured to determine a cyclic shift to apply to the PUCCH based on the determination that the failure is due to beam blocking, or based on the format of the PUCCH, or a combination thereof.

Abstract: Aspects of the disclosure relate to devices, systems and methods for multi-beam formation. A user equipment (UE) may determine a sampling interval for references signals to be transmitted by a base station for an upcoming control or data communication. For example, the UE may determine a maximum sampling interval tolerable for channel estimation and select the sampling interval based on the maximum. In some examples, the UE determines the sampling interval based on characteristics of its motion. The UE transmits an indication of the sampling interval to the base station. Based on the indication, the base station selects an interval for the reference signals and transmits the reference signals to the UE to enable it to perform the channel estimation for the multi-beam. The base station may determine to select the interval for the reference signals such that it is less than or equal to the sampling interval indicated by the UE.
