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: 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: A dual frequency synthesizer architecture for a wireless device operating in a time division duplex (TDD) mode is disclosed. In an exemplary design, the wireless device includes first and second frequency synthesizers. The first frequency synthesizer generates a first oscillator signal used to generate a first/receive local oscillator (LO) signal at an LO frequency for the receiver. The second frequency synthesizer generates a second oscillator signal used to generate a second/transmit LO signal at the same LO frequency for the transmitter. The two frequency synthesizers generate their oscillator signals to obtain receive and transmit LO signals at the same LO frequency when the wireless device operates in the TDD mode.
