Abstract: An antenna system having an antenna array including at least first and second phased array antennas, and a method for field-calibrating the antenna array. Before and after a handover period, communication with respective first and second external satellites or other communication systems is performed using both the first and second antennas. A first beam is formed prior to the handover period. During a first portion of the handover period: a second beam is formed for the communication with the first satellite using the first antenna; the second antenna is deactivated for external communication; and the second antenna is calibrated. During a second portion of the handover period, the second antenna is reactivated for a handed over communication with the second satellite by forming a third beam using the second antenna, while the first antenna maintains its communication with the first satellite via the second beam.

Abstract: An example method of wireless data transmission may include determining a configuration of multiple antenna element nodes. The configuration may indicate a frequency band of operation for each of the multiple antenna element nodes and the configuration may be determined based on one or more network factors of multiple frequency bands. The method may also include selecting, based on the configuration, a signal path to couple to each of the multiple antenna element nodes from multiple signal paths. The multiple signal paths may each be configured to amplify signals carried thereon and at least two of the multiple signal paths may be coupled between each antenna element node and a common node. The method may further include directing, based on the configuration, wireless communications over the multiple antenna element nodes.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may generate a recommendation for a first codebook that is for a single transmit receive point (TRP) and that does not include a time domain (TD) or Doppler domain (DD) basis, or for a second codebook that is for multiple TRPs or that includes a TD or DD basis. The UE may transmit the recommendation. Numerous other aspects are described.

Abstract: In an example method, a user equipment (UE) device determines one or more component carriers available to the UE device for at least one of transmitting or receiving data over a wireless network. The UE device transmits, to the wireless network, for each component carrier, an indication whether the component carrier supports at least one of transmitting or receiving data according to a multi-transmission and receiving points (multi-TRP) communication protocol.

Abstract: According to one embodiment, a wireless base station includes a transmitter and a receiver. The transmitter transmits a control signal and one or more operation signals to the second wireless communication terminal. The control signal instructs to transmit a signal that requests terminal-to-terminal communication between a first wireless communication terminal and the second wireless communication terminal. The operation signals are used for operating at least a part of the first wireless communication terminal. The receiver is capable of receiving at least one of a response signal or a data signal transmitted from the first wireless communication terminal to the second wireless communication terminal after the operation signals are transmitted.
