Abstract: Methods, systems, and devices for wireless communications are described. The method, systems, and devices may include techniques for establishing a first connection with a first cell operating in accordance with a first radio access technology (RAT), and performing a beam sweep procedure for one or more candidate beams for adding or handover to a second cell operating in accordance with millimeter wave (mmW) RAT. The beam sweep procedure may be performed based on previous beam measurements stored in a measurement database. The techniques may further include selecting a beam from the one or more candidate beams for adding or handover to the second cell based on the beam sweep procedure, and adding or handing over to the second cell by establishing a second connection with the second cell using the selected beam.

Abstract: A UE determines a default beam for a physical downlink shared channel (PDSCH) that is independent of a beam for a physical downlink control channel (PDCCH). The default PDSCH beam may be determined based on information received in a medium access control-control element (MAC-CE), or a radio resource control (RRC) message, a downlink control information (DCI). The default PDSCH beam may be determined based on at least one active transmission configuration indication (TCI) state for the PDSCH.

Abstract: The choice of a transmit (Tx)-Receive (Rx) beam pair out of many available beam pairs between a base station and a millimeter wave (mmW)-capable UE is directly related to the performance of transmission between the base station and the UE. A method, apparatus, and computer-readable medium at a transmitting user equipment (UE) capable of (mmW) communication are disclosed to determine a new serving Tx-Rx beam pair using an artificial neural network. The UE may predict a set of good Tx-Rx beam pairs using the artificial neural network, wherein the artificial neural network comprises an input layer, a middle layer, and an output layer. The UE may then determine the new serving Tx-Rx beam pair based on the set of good Tx-Rx beam pairs.

Abstract: The choice of a transmit (Tx)-Receive (Rx) beam pair out of many available beam pairs between a base station and a millimeter wave (mmW)-capable UE is directly related to the performance of transmission between the base station and the UE. A method, apparatus, and computer-readable medium at a transmitting user equipment (UE) capable of (mmW) communication are disclosed to determine a new serving Tx-Rx beam pair based on cumulative strengths of a plurality of Tx-Rx beam pairs. The UE may iteratively perform a process of, until a predetermined number of synchronization cycles is reached: selecting one of the plurality of Transmit (Tx)-Receive (Rx) beam pairs based at least in part on a scheduling opportunity value of the selected Tx-Rx beam pair that has not been measured for a current synchronization period; and measuring a strength of the selected Tx-Rx beam pair.

Abstract: Aspects of the disclosure relate to a method of operating a scheduled entity for wireless communication with a network. In some aspects, the scheduled entity transmits a message that requests a scheduling entity to transmit at least one reference signal. The scheduled entity obtains channel state information based on the at least one reference signal. The scheduled entity transmits a report that includes the channel state information. In other aspects, the scheduled entity transmits a message that requests a scheduling entity to schedule a reference signal transmission for the scheduled entity. The scheduled entity obtains an assignment of resources for transmission of the reference signal in response to the message. The scheduled entity transmits the reference signal based on the assignment of resources. Other aspects, embodiments, and features are also claimed and described.

Abstract: Certain aspects of the present disclosure propose techniques for independently signaling features supported by a user equipment (UE) in different duplexing modes. The UE may be capable of communicating in frequency division duplexing (FDD) and time division duplexing (TDD) modes. The UE may obtain a FDD-specific feature group indicators (FGIs) set and a TDD-specific FGIs set, and signal at least one of the FDD-specific FGIs set or TDD-specific FGIs set. In addition, the UE may take one or more actions to reduce the likelihood of transitioning to a mode of operation that is different from its current mode of operation.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a mapping of more than one antenna element, associated with an antenna module or panel that is integrated with a radio frequency integrated circuit (RFIC), to an RFIC port via one or more switches. The UE may select antenna elements from the more than one antenna element based at least in part on one or more conditions being satisfied. The UE may perform, via the antenna elements, a communication to a network node. Numerous other aspects are described.
