Abstract: An apparatus is disclosed for flexible beamforming using frequency-division multiplexing. In an example aspect, an apparatus includes an antenna array and a wireless transceiver with two or more dedicated receive paths respectively coupled to two or more antenna elements of the antenna array, two or more mixers, a first combiner, a second combiner, and a switching circuit. The first combiner has a first input coupled to a first dedicated receive path and an output coupled to an input of a first mixer. The second combiner has a first input coupled to an output of the first mixer and a second input coupled to an output of a second mixer. The switching circuit is configured to selectively connect a second dedicated receive path to a second input of the first combiner or connect the second dedicated receive path to an input of the second mixer.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a first device and a second device may communicate over a communication link using a set of antenna elements. The first device may identify one or more antenna array reconfiguration trigger conditions and may correspondingly select a first subset of antenna elements for operation. The first device may transmit a message to the second device including an indication of the antenna array reconfiguration at the first device, a request for the second device to modify the second device's antenna array configuration, or both. The second device may receive the message and, based on the indication or the request, may modify its antenna array configuration. For example, the second device may select a second subset of antenna elements based on the selected first subset of antenna elements. The devices may communicate using their modified antenna array configurations.

Abstract: Various aspects of the disclosure relate to communicating uplink control information. As one example, a user equipment may send uplink control information to a base station. In some aspects, the number of symbols used to communicate the uplink control information may be based on a link gain associated with the UE and/or based on a payload size of the uplink control information. As another example, the user equipment may send channel information for a number of beams to the base station. In some aspects, the number of beams may be based on the type of channel that is used to send the uplink control information.

Abstract: Certain aspects of the present disclosure provide techniques for signaling information regarding beams used for data and control transmissions to a UE. For example, a method for wireless communications by a user equipment (UE), may generally include signaling information to a base station (BS) that the UE is seeking recovery of a beamformed link between the BS and the UE, and participating in recovery of the beamformed link in accordance with the information. A method for wireless communications by a base station (BS), may generally include receiving information from a user equipment (UE) that the UE is seeking recovery of a beamformed link between the BS and the UE, and participating in recovery of the beamformed link in accordance with the information.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. A wireless node may determine a pattern for transmitting multiple synchronization communications in one or more synchronization communication sets. The wireless node may determine a set of resources, in the one or more synchronization communication sets, to be used to transmit the multiple synchronization communications based at least in part on the pattern. The wireless node may transmit the multiple synchronization communications using the set of resources. A first synchronization communication, of the multiple synchronization communications, may be frequency division multiplexed with a second synchronization communication. Numerous other aspects are provided.

Abstract: Aspects of the disclosure relate to a method of operating a scheduled entity for wireless communication. In some aspects, the scheduled entity detects a fluctuation in a beam strength of at least one transmit beam from a scheduling entity. The scheduled entity transmits a first message to the scheduling entity, the first message indicating at least the fluctuation in the beam strength of the at least one transmit beam from the scheduling entity.

Abstract: In aspects, a user equipment may be configured to determine a preconfigured frequency band that is less than an available system bandwidth. The UE may be further configured to perform an initial access procedure with a base station using the preconfigured frequency band. The initial access procedure may include a random access channel (RACH) procedure.
