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: The transmission and reception group delay in a front end structure of a mobile device may be determined using closed loop calibration. The closed loop may be a near field radiated closed loop between pairs of antennas in an antenna array of the mobile device. The delay based on time of transmission and time of reception may be measured for a plurality of pairs of antennas, from which the transmit and receive group delay within a single path may be determined. The propagation delay of the signal between antennas may be included in the group delay calibration for increased accuracy. In another implementation, a conducted closed loop, e.g., in the transceiver or in a radio frequency switching network may be used to calibrate the group delay. Pre-characterization of the delay caused by components between the closed loop and antennas may be included in the group delay calibration for increased accuracy.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may transmit capability information including an indication of a discontinuous monitoring delay period. The UE may receive a message including an indication to adjust monitoring of a physical downlink control channel (PDCCH), and monitor for the PDCCH during the discontinuous monitoring delay period. The UE may adjust monitoring for the PDCCH following the discontinuous monitoring delay period during a temporal period based on the received indication to adjust monitoring of the PDCCH. In some examples, at least one of physical downlink shared channel (PDSCH) reception, downlink reference signal monitoring, uplink reference signal transmissions, and channel reporting is enabled during the temporal period while monitoring of the PDCCH is adjusted.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration signal indicating a codebook construction configuration for constructing a codebook of sequences for conveying a first type of uplink payload in a resource block that is orthogonal to a second type of uplink payload transmitted from a second UE in the resource block. The UE may construct the codebook of sequences for the first type of uplink payload according to the codebook construction configuration. The UE may generate the first type of uplink payload for transmission using a first sequence from the codebook of sequences. The UE may transmit the first type of uplink payload in the resource block, wherein the first type of uplink payload is multiplexed in the resource block with the second type of uplink payload from the second UE.

Abstract: The disclosure relates in some aspects to an energy-aware architecture that supports a low power scheduling mode. For example, a media access control (MAC) architecture for a base station (e.g., an enhanced Node B) and associated access terminals (e.g., UEs) can take the power needs of the access terminals into account when scheduling the access terminals. In some aspects, an access terminal may support a particular frame structure for a low power mode. Accordingly, scheduling of the access terminal may include use of the particular frame structure during low power mode.

Abstract: In an aspect, a UE obtains information (e.g., UE-specific information) associated with a set of triggering criteria (e.g., from a server, a serving network, e.g., in conjunction with or separate from a set of neural network functions) for a set of neural network functions. The UE obtains positioning measurement data associated with a location of the UE, and processes the positioning measurement data into a respective set of positioning measurement features based at least in part upon the positioning measurement data and at least one neural network function from the set of neural network functions that is triggered by at least one triggering criterion from the set of triggering criteria. The UE reports the processed set of positioning measurement features to a network component (e.g., BS, LMF, etc.).

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: Aspects enable and provide techniques for sidelink communication resource configuration and management. A first user equipment (UE) negotiates with a second UE to select a first communication resource set (ComReSet) from a plurality of ComReSets for sidelink communication. Each of the plurality of ComReSets has a corresponding periodicity of one or more hyper-frames. The first UE communicates with the second UE using the first ComReSet using a frame timing synchronized with the corresponding periodicity of the first ComReSet.

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.
