A method of multibeam steering includes determining, by a user equipment (UE) equipped with a plurality of antenna elements, a plurality of amplitude values and a plurality of phase values for the multibeam steering; and generating, simultaneously, a first beam and a second beam based on the plurality of amplitude values and the plurality of phase values.

A system, method and apparatus for wireless communications is provided. A user equipment (UE) transmit a capability message comprising an information element indicating that the first UE is capable of establishing multiple sidelinks with at one additional UE. The UE receives one or more radio resource control (RRC) messages comprising configuration parameters for establishing multiple sidelinks with the at least one additional UE. The UE establishes communications with the at least one additional UE using the multiple sidelinks based on the received configuration parameters.

Sidelink user equipment (UE) capability signaling enhancement

A system, method and apparatus for wireless communications is provided. A user equipment (UE) receives, from a first base station, one or more first messages that include measurement configuration parameters and sidelink parameters associated with a first cell. The UE establishes a sidelink with a second UE based on the sidelink parameters and transmits, to the first base station, a measurement report based on the measurement configuration parameters. Responsive to the measurement report, the UE receives a second message comprising second configuration parameters of a second cell of a second base station. The second configuration parameters do not comprise sidelink parameters. The UE then switches from the first cell of the first base station to the second cell of the second base station. The sidelink of the first cell is handed over to an uplink of the second cell.

A system, method and apparatus for mobile communications including sidelink transmissions is provided. A user equipment (UE) receives configuration parameters of a cell for sidelink communications with a second UE that includes configuration parameters for a first bandwidth part (BWP) and a second BWP of the cell. The first configuration parameters indicate first radio resources of the cell and a first numerology for the first BWP. The second configuration parameters indicate second radio resources of the cell and a second numerology for the second BWP. The UE transmits the one or more first sidelink signals and channels via the first BWP and based on the first configuration parameters. The UE then receives one or more second sidelink signals and channels via the second BWP and based on the second configuration parameters.

A method of data transmission in a 5G network includes receiving, by an internet of things (IoT) device, one or more configuration parameters associated with a prediction-based model; performing a measurement by the IoT device; determining, by the IoT device, a first data sample based on the measurement performed by the IoT device; determining, by the IoT device based on the prediction-based model and using the one or more configuration parameters, whether to transmit the first data sample to a non-terrestrial networking (NTN) node; and transmitting the first data sample to the NTN node in response to determining to transmit the first data sample. The transmitting may indicate that a predicted value corresponding to the first data sample is erroneous.
