Abstract: An apparatus, which comprises at least one antenna array comprising a plurality of array elements having cross-polarized coupled branches, is configured to adjust at least its uplink beam steering direction by measuring (301), while transmitting a combined uplink signal via the plurality of the an-ay elements as individual signals forming the combined uplink signal, per an array element, first signal on an unused branch of the array element, and using the first signal and reference information in the memory to adjust if needed, at least one beam steering setting.

Abstract: Systems, methods, apparatuses, and computer program products for robust radio resource allocation for uplink radar and other user equipment calibration are provided. For example, a method may include receiving, at a network element, measurements of a set of synchronization signal blocks or channel state information reference signals or both synchronization signal blocks and channel state information reference signals from a user equipment. The method may additionally include sending to the user equipment a direct or indirect indication of a random access opportunity corresponding to a synchronization signal block index value or channel state information reference signal index value, wherein the indication is for usage to perform user equipment calibration.

Abstract: An apparatus comprising:



a switching arrangement configured to split an antenna array panel, comprising an array of antenna elements, to provide a first part for a first downlink beam from a first transmitter and a second part for a second downlink beam from a second transmitter, wherein the first downlink beam and the second downlink beam have independent directions; and
the switching arrangement being configured to enable inter-band carrier aggregation at receiver circuitry using a first component carrier received at the first part of the antenna array panel via the first downlink beam and a second component carrier received at the second part of the antenna array panel via the second downlink beam.
