    Abstract: Methods, systems, and devices for wireless communication are described. The method may include transmitting a first synchronization signal in a set of beam directions during a first symbol period of a synchronization subframe and transmitting a second synchronization signal in another set of beam directions during a second symbol period of the synchronization subframe. The second set of beam directions may be spatially interleaved with the first set of beam directions. Additionally, the method may include monitoring a first and second set of beam directions during a first and second symbol period of a random access subframe, respectively. Additionally, the method may include receiving, from a base station, first and second synchronization signals in a synchronization subframe, decoding the first synchronization signal, and transmitting an access request based at least in part on the decoded first synchronization signal.

    Abstract: Methods, systems, devices, and apparatuses are described for phase noise estimation. A transmitting device identifies a phase noise metric associated with a receiving device. The phase noise metric provides an indication of the expected phase noise for the receiving device. The transmitting device selects a plurality of pilot tones adjacent to each other and a plurality of null tones for a transmission to the receiving device based on the phase noise metric. The plurality of null tones may be adjacent to and on both sides of the pilot tones in the frequency domain. The transmitting device identifies its own phase noise metric and select the pilot tones adjacent to each other and plurality of null tones in further consideration of its own phase noise metric. The receiving device may use the pilot tones and plurality of adjacent null tones to determine a phase noise estimation for the transmission.

    Abstract: Described herein are methods, systems, and apparatus for jointly estimating channel and phase noise in a control symbol. In one example, a method for wireless communication is described that includes inserting a control tone at a first periodicity in a first subcarrier of a control symbol and inserting a pilot tone at a second periodicity in a second subcarrier of the control symbol, the pilot tone being offset from the control tone in the control symbol. The method also includes transmitting the control symbol. In another example, a method for wireless communication is described that includes receiving a control symbol comprising a control tone at a first periodicity, and a pilot tone at a second periodicity, the pilot tone being offset from the control tone in the control symbol. The method also includes performing a phase noise estimation and a channel estimation from the pilot tone.

    Abstract: Methods, systems, and devices are described for wireless communication at a user equipment (UE). A wireless communications system may improve UE discovery latency by dynamically selecting and switching beam forming codebooks at the millimeter wave base station and the wireless device. Selecting an optimal beam forming codebook may allow the wireless communication system to improve link margins between the base station without compromising resources. In some examples, a wireless device may determine whether the received signals from the millimeter wave base station satisfy established signal to noise (SNR) thresholds, and select an optimal beam codebook to establish communication. Additionally or alternately, the wireless device may further signal the selected beam codebook to the millimeter wave base station and direct the millimeter wave base station to adjust its codebook based on the selection.

    Abstract: This disclosure provides systems, methods, apparatuses, and computer programs encoded on computer storage media, for wireless communication. Various aspects support beam switching and changing antenna array configurations for communicating in a near field range. In some examples, a user equipment (UE) may transmit a beam group indicator to a network entity, and the UE and the network entity may perform beam switching operations associated with switch communication beams in association with changes to a distance between the UE and the network entity. In some such examples, the beam switching may switch from using beam weights for communications in a far field range to beam weights for communications in a near field range. Additionally or alternatively, the network entity may change configurations of an antenna array used to communicate with the UE in association with changes to the distance. Other aspects and features are also claimed and described.

    Abstract: This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, for wireless communication. In one aspect of the disclosure, a method for wireless communication performed by a user equipment (UE) includes receiving, from a base station, mapping information indicating, for each bandwidth part (BWP) of multiple BWPs, a mapping between a respective beam direction of multiple beam directions and the BWP. The method further includes receiving an allocation of a first BWP. The method also includes communicating, via the first BWP, one or more first messages using a first beam having a first beam direction, and receiving, from the base station, a change indicator associated with a second BWP or a second beam direction. The method includes communicating, via the second BWP, one or more second messages using a second beam having a second beam direction. Other aspects and features are also claimed and described.
