Abstract: Methods, systems, and devices for wireless communication are described. In some systems, a user equipment (UE) may transmit, to a network entity, a first signal including a request to update a resolution of a phase shifting operation associated with beam-based communications. The UE may receive, from the network entity, a second signal approving the request. The UE may communicate using a beam according to an updated resolution of the phase shifting operation based on the second signal approving the request. Additionally, or alternatively, the UE may transmit a first signal including a request to suspend a beam refinement process based on the resolution of the phase shifting operation. The UE may receive a second signal approving the request to suspend the beam refinement process. The UE may communicate with the network entity using a beam based on suspending further beam refinement in response to the second signal.

The apparatus may be configured to select one of a first beam or a second beam for the transmission of the uplink signal based on the PSD. The second beam may be wider than the first beam, and may be generated by a single antenna element of the apparatus. The apparatus may be configured to transmit the uplink signal using the selected one of the first beam or the second beam.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may transmit, to a second wireless device, capability control signaling indicating a first quantity of beam switches is supported within a first time period for a first antenna subarray, a first antenna module, or both, of the first wireless device. The first wireless device may receive from the second wireless device in accordance with the capability control signaling, a grant scheduling one or more messages and indicating a set of beams of the first wireless device over which to communicate the one or more messages in respective transmission time intervals (TTIs) of the first time period. The first wireless device may then transmit or receive, over the first time period using the first antenna subarray, the first antenna module, or both, the one or more messages using the set of beams.

Abstract: Wireless communication system may be configured to use different frequency bands for uplink communication and downlink communication. For example, a wireless system may use multiple frequency bands for downlink with carrier aggregation, and the wireless system may use only one frequency band for uplink. Up-conversion and down-conversion between baseband signals and RF signals, using a fixed frequency local oscillator signal may cause energy leak to an adjacent frequency band during transmission of signal and may result in interferences to other radio communication devices using the adjacent bands. To limit the amount of energy that leaks out of its assigned radio frequency bands, the UE may use local oscillator signals with different frequencies for up-conversion and down-conversion and may switch the frequencies of the local oscillator signals between reception of downlink signals and transmission of uplink signals.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may be communicating with a base station via beamformed transmissions on an active beam. The UE may receive from the base station refined reference signals (RRSs) that include an active beam RRS corresponding to the active beam. The UE may identify that the active beam RRS corresponds to the active beam and perform a beam state measurement on the active beam RRS. The UE may refine the active beam based at least in part on the beam state information of the active beam RRS.

Abstract: An apparatus is disclosed for jammer detection. In example aspects, the apparatus includes a wireless transceiver configured to be connected to one or more antennas. The wireless transceiver is configured to translate a received signal from a first frequency to a second frequency using a reference signal to produce a translated received signal, with the reference signal including at least one frequency having an association with one or more targeted frequencies of a potential jamming signal. The wireless transceiver is also configured to convert at least a version of the translated received signal in the analog domain into a converted received signal in the digital domain. The wireless transceiver is further configured to detect that the converted received signal comprises a jamming signal based on the association and using at least one threshold and determine a jamming frequency of the jamming signal based on the frequency of the reference signal.
