Abstract: Methods, systems, and devices for wireless communication are described. A base station may identify a sounding reference signal (SRS) configuration for user equipment (UE). The base station may transmit an SRS grant message to a UE indicating the SRS configuration. An indication of SRS parameters may be included in the SRS grant message, and may include the SRS parameters or a location of the SRS parameters. That is, SRS parameters may be transmitted in a control channel with the SRS grant message or may be separately sent in a data channel as indicated by the indication of SRS parameters. In some cases, SRS parameters may be determined based on previously received UE feedback regarding channel conditions or power limitations. Alternatively, the base station may make its own environment measurements or assign SRS parameters autonomously. The UE may signal SRS transmissions to the base station according to the SRS grant message.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for generating synchronization signals for cell synchronization. Certain aspects of the present disclosure provide a method for wireless communication. The method generally includes determining a symbol index for transmitting a sequence; determining an amount of cyclical shift in one of a frequency domain and a time domain to apply to the Zadoff-Chu sequence, wherein the amount of cyclical shift in the frequency domain is based on the sequence and the symbol index; shifting the sequence by the amount of cyclical shift; and transmitting the shifted sequence in a symbol corresponding to the symbol index. Consequently subframe synchronization can be acquired by detecting one synchronization symbol and uniquely identifying its cyclic shift applied to the ZC sequence.

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: Techniques are described for backhaul operations in a millimeter wave wireless communication system. A first base station of the millimeter wave wireless communication system identifies an access demand and one or more access communication parameters associated with the first base station. The first base station sends information to a second base station indicative of the access demand and the one or more access communication parameters, and determines one or more backhaul communication parameters associated with the second base station of the millimeter wave wireless communication system. The first base station establishes a wireless backhaul link with the second base station via the millimeter wave wireless communication system. The first base station partitions resources between an access link with one or more user equipments and the established wireless backhaul link based at least in part on the access demand, the one or more access communication parameters, or the backhaul communication parameters.

Abstract: A beamforming configuration is changed during a cyclic prefix that precedes a symbol period. For example, the beamforming configuration for a transmitter can be changed during an orthogonal frequency-division multiplexing (OFDM) cyclic prefix that precedes a fast Fourier transform (FFT) window. In this way, there is no loss of data signaling due to the transmitter reconfiguring its beamforming.
