Abstract: Methods, systems, and devices for wireless communications are described. A first device and a second device may communicate via a channel. The first device may generate and transmit a reference signal, which may be a distortion probing reference signal with a high peak to average power ratio. In one implementation, the first device may use the reference signal as an input for a neural network model to learn a nonlinear response of the second device transmission components. In another implementation, the second device may sample the generated reference signal, and use the samples as inputs for a neural network model to learn the nonlinear response. The first device and the second device may exchange signaling based on learning the nonlinear response, and each device may compensate for the nonlinear response when communicating via the channel.

Abstract: Systems and techniques are disclosed to reduce pilot overhead by providing common reference signals coded with cover codes that are orthogonal in time and frequency domains. Common reference signals that are coded by cover codes orthogonal in both domains can be de-spread in both the time and frequency domains for improved resolution and larger pull-in windows for both. Also disclosed is semi-uniform pilot spacing in both the frequency and time domains. In a time domain, a first pilot symbol pair is spaced by a first time interval from each other and a second pilot symbol pair is spaced by a second time interval from the first pair, the second interval being greater than the first. In a frequency domain, a first set of pilot symbols is densely placed in a selected frequency band and a second set of pilot symbols is sparsely placed surrounding and including the selected frequency band.

Abstract: Methods, systems, and devices for wireless communication are described. Some wireless communications systems (e.g., New Radio (NR) systems) may support the dynamic configuration of time intervals (or slots) for communication in a specific link direction (e.g., uplink, downlink, sidelink, etc.). In such cases, a base station may dynamically allocate time intervals (or slots) for broadcast or multicast data (e.g., via a physical downlink control channel (PDCCH)) based on the dynamically determined configuration of certain time intervals (or slots). The dynamic allocation of resources for broadcast or multicast data may ensure that broadcast or multicast data is not scheduled to be transmitted during time intervals configured for uplink communication. In some cases, the broadcast or multicast data may be transmitted on a portion of a system bandwidth that is frequency division multiplexed with another portion of the system bandwidth allocated for mobile broadband (MBB) communications.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit, to a user equipment (UE), a configuration of a radio link monitoring resource for a radio link that transports downlink traffic for a first type of service, the first type of service having a higher reliability specification and a lower latency specification than a second type of service offered by the base station. The UE may receive the configuration, and detect that the radio link satisfies a failure condition for the first type of service based on monitoring the RLM resource. The UE may transmit a radio link failure (RLF) indication for the first type of service to the base station based on detecting that the radio link satisfies the failure condition for the first type of service. The base station may receive the RLF from the UE, and transmit an RLF response to the UE.

Abstract: Certain aspects of the present disclosure provide techniques for ordering a plurality of potential base stations to serve a user equipment on a supplemental uplink and providing random access channel (RACH) configuration parameters for each of the plurality of potential base stations to the user equipment. Certain aspects provide a method for wireless communication. The method generally includes communicating, by a user equipment (UE), with a first base station (BS) on a downlink on a first frequency band. The method further includes receiving, by the UE from the first BS, a list comprising RACH configuration parameters for each of a plurality of BSs. The method further includes selecting a second BS from the plurality of BSs based on an ordering of the plurality of BSs in the list and performing a RACH procedure with the second BS.

Abstract: The disclosed methods and apparatuses for round trip time (RTT) based positioning include generating or receiving a measurement report. The measurement report includes, for at least one transmission-reception point (TRP), a user equipment (UE) time difference and an offset of the at least one TRP. The UE time difference is a difference of a UE transmission time of an uplink reference signals (UL RS) to the at least one TRP and an earliest reception time representing a time of arrival (TOA) at the UE of an earliest path of a downlink reference signal (DL RS) from the at least one transmission-reception point (TRP). The offset is a difference of a stronger reception time representing a TOA at the UE of a stronger path of the DL RS from the at least one TRP and the earliest reception time.

Abstract: Systems, methods, apparatuses, and computer-readable storage media for managing power consumption of a mobile device are disclosed. The systems, method, apparatus, and computer-readable storage medium may cause the base station to identify an energy metric associated with a mobile device, and to configure the transmission between the base station and the mobile device based at least in part on the energy metric. The configuration of the transmission may reduce the power consumption of the mobile device for processing the transmission.

Abstract: Aspects of the present disclosure provide for the pairing of an inter-band carrier with a time division duplex (TDD) carrier. If the paired band is a frequency division duplex (FDD) band, then base stations and mobile devices may transmit and receive additional thin control channels on FDD carriers to enable full duplex operations. If the paired band is a TDD band, then a conjugate or inverse carrier may be used such that full duplex, or a close approximation thereto, is achieved. With the introduction of a paired channel and fast control channels, rapid uplink/downlink switching may be achieved for TDD carriers efficiently and effectively. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be capable of operating according to a first transmission efficiency operating mode and a second transmission efficiency operating mode that is less power efficient than the first transmission efficiency operating mode. The first transmission efficiency operating mode may be associated with a first undesired emission level that is greater than a second undesired emission level associated with the second transmission efficiency operating mode. The UE may select to operate in one of the two transmission efficiency operating modes based on one or more communication parameters (e.g., indicated by control signaling received from a base station). For example, the UE may select to operate in the first transmission efficiency operating mode based on determining that one or more of the communication parameters satisfies at least one parameter criterion for operating in the first transmission efficiency operating mode.
