Abstract: Wireless communications systems and methods related to communicating in an integrated access backhaul (IAB) network are provided. A first wireless communication device receives synchronization information associated with one or more wireless communication of a multi-hop wireless network. The first wireless communication device determines a transmission timing adjustment for a second wireless communication device of the one or more wireless communication devices based on at least some of the synchronization information. The first wireless communication device transmits a message instructing the second wireless communication device to communicate with a third wireless communication device of the one or more wireless communication devices based on the transmission timing adjustment.

Abstract: High frequency wireless communication networks rely on directional transmit and receive beams to achieve large gains and overcome large pathlosses associated with high frequency signals. With highly directional signals, link failure may occur. Network nodes associated with the link failure, may need to identify new beam pairs and establish a new link as quickly as possible. In several aspects, beam sweep procedures are expedited, allowing for rapid link reestablishment. Disclosed techniques allow for rapid link reestablishment with and without beam correspondence.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, control signaling configuring the UE to use a first waveform for communicating via a first beam and a second waveform for communicating via a second beam, the first waveform being different than the second waveform. The UE may communicate a first data transmission via the first beam using the first waveform and communicate a second data transmission via the second beam using the second waveform.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit, to a base station, feedback information that indicates delay spread information. The UE may receive control signaling that indicates to use a first waveform of a set of different waveforms for a first data transmission via a first beam based on the feedback information. The UE may then communicate the first data transmission via the first beam using the first waveform

Abstract: Disclosed are techniques for using a channel state information (CSI) report framework to support positioning measurements in a wireless network. More particularly, a base station may identify one or more reference signal resources to be transmitted to a user equipment (UE) for obtaining at least one positioning measurement and configure the reference signal resources to be transmitted at least partially outside a current bandwidth that the base station and the UE are using to communicate data and control information. Accordingly, the base station may transmit, to the UE, a CSI report setting that indicates the positioning measurement to be reported and specifies that the positioning measurement is to be obtained from the configured reference signal resources.

Abstract: Methods, systems, and devices for wireless communications are described for phase error estimation and correction with sub-symbol resolution. A transmitting device may precode symbols (e.g., phase tracking reference signal (PT-RS) symbols) using a discrete Fourier transform (DFT). The transmitting device may map the DFT-precoded symbols to sets of adjacent subcarriers of a wireless signal, and may map other symbols to other subcarriers of the wireless signal. A receiving device may receive the wireless signal and may compare time domain representations of the DFT-precoded symbols with time domain representations of known reference symbols. The receiving device may estimate a phase error with sub-symbol resolution in the time domain based at least in part on the comparison, and may apply a phase correction in either the time or frequency domain to the other symbols.

Abstract: Methods, systems, and devices for wireless communication are described. Some examples provide for identifying a primary synchronization signal (PSS) sequence of a synchronization subframe, determining, for the synchronization subframe, an extended synchronization signal (ESS) sequence based at least in part on the PSS sequence and transmitting the synchronization subframe. Other examples provide for generating an ESS sequence for a synchronization subframe to be communicated to a UE, scrambling the ESS sequence based at least in part on cell-specific information associated with the base station and transmitting, to the UE, the scrambled ESS sequence in the synchronization subframe.
