Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an apparatus for wireless communication at a wireless node comprises one or more memories, and one or more processors, coupled to the memory. The one or more processors can be configured to transmit or receive tri-state feedback indicating a result of decoding one or more communications. The tri-state feedback can be associated with three potential states. The three potential states can indicate whether (i) decoding of a control channel was unsuccessful, (ii) decoding of the control channel was successful and decoding of a data channel was unsuccessful, or (iii) decoding of the control channel and the data channel was successful.

Abstract: Various aspects described herein relate to techniques for synchronization channel design and signaling in wireless communications systems (e.g., a 5th Generation (5G) New Radio (NR) system). In an aspect, a method includes identifying a frequency band supported by a user equipment (UE), identifying one or more frequency locations based on the identified frequency band, and the one or more frequency locations are a subset of synchronization raster points used for synchronization signal transmission. The method further includes searching for at least one synchronization signal based on the one or more identified frequency locations.

Abstract: Techniques are described for wireless communication. One method includes identifying a traffic condition associated with data to be transmitted between a network access device and at least one user equipment (UE); selecting, based at least in part on the traffic condition, a dynamic subframe type of a time-division duplex (TDD) subframe; and indicating the dynamic subframe type in a TDD header of the TDD subframe. Another method includes identifying, in a TDD header of a subframe, an indication of a dynamic subframe type of the TDD subframe; and transmitting data or receiving data in a data region of the TDD subframe based at least in part on the dynamic subframe type.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a device such as a user equipment (UE), a base station, or both, to perform a channel noise and interference estimation based on a set of null resources in a data channel. The device may identify a first configuration for a set of demodulation reference signals (DMRSs) in a first set of time periods of a data channel and a second configuration for a set of null resources in a second set of time periods of the data channel. The second set of time periods may be nonoverlapping with the first set of time periods. The device may perform a channel estimation procedure on the data channel based on the null resources and the DMRS resources. The device may process data received via resources of the data channel based on the channel estimation procedure.

Abstract: Wireless devices can use various super-slot formats to facilitate wireless communication using half duplex (HD) frequency-division duplex (FDD) (HD-FDD). A super-slot has a duration that can span over multiple slots and/or subframes. A super-slot can include uplink symbols and downlink symbols. The super-slot can include a guard period that separates uplink symbols from downlink symbols in the same super-slot. A super-slot can support signal repetition to provide coverage enhancement. Signal repetition can be combined with frequency hopping in a super-slot to provide diversity gain.

Abstract: A user equipment (UE) generates a positioning state information (PSI) report that is transmitted in a lower layer channel container, e.g., in the Physical channel or Medium Access Control channel, to a network entity to reduce latency. The PSI report is generated based on a plurality of PSI report elements determined from uplink (UL), downlink (DL) or UL and DL positioning measurements performed by the UE. Each PSI report element includes information related to positioning measurements performed by the UE. The transmission of at least one PSI report element generated by the UE may be postponed and not included in a current PSI report. The PSI report includes one or more indications of postponement, indicating that one or more PSI report elements have been postponed. A serving base station may grant a lower layer channel container for a second PSI report to contain the previously postponed PSI report elements.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives, during one or more time units up to a first time, a configuration to provide a positioning state information (PSI) report, measures, after the first time up to a second time, one or more positioning reference signal (PRS) transmissions, and transmits, at a third time after the second time, the PSI report on an uplink physical channel, the PSI report including measurements of the one or more PRS resources, wherein a length of time between the second time and the third time is greater than a timing requirement Z′.
