Abstract: A UE in one of an RRC idle mode or an RRC inactive mode may generate an emergency message including one or more of GPS coordinates, a timestamp, a UE ID, a personal ID of a user of the UE, an emergency level, or an emergency type, and transmit the emergency message to an NR-NTN. The emergency message may be transmitted in a dedicated time or frequency resource. The base station may receive the emergency message from the UE and forward the UE information to a network.

Abstract: Apparatus, methods, and computer-readable media for network coding for dual connectivity are disclosed herein. A base station (BS) sends encoded symbols from a first network coding layer to a first radio link control (RLC) layer and transmits, to a user equipment (UE), encoded data comprising the encoded symbols. The BS also transmits encoded data to a road side unit (RSU) for passing to the UE as a split transmission. The UE can receive encoded packets from the BS and RSU at a network coding layer via a second RLC layer. The UE recovers source packets from the encoded packets with a rateless network code at the network coding layer. The UE sequences the source packets into an ordered set of source packets at the network coding layer and sends the ordered set of source packets from the network coding layer to a packet data convergence protocol layer for processing.

Abstract: Techniques are described for wireless communication. An orthogonal frequency-division multiple access (OFDMA) configuration of an uplink channel is identified for communications in an unlicensed radio frequency spectrum band. An OFDMA waveform is generated based on the identified OFDMA configuration. The OFDMA waveform is communicated in a signal in the unlicensed radio frequency spectrum band. A virtual cell identifier of a first base station may be associated with transmissions between the first base station and a first user equipment (UE). A set of common resource blocks may be identified for transmission of a demodulation reference signal (DM-RS) between the first base station and the first UE. A configuration of an uplink channel may be dynamically selected for uplink communications in an unlicensed radio frequency spectrum band. A waveform may be generated based on the selected configuration. The waveform may be communicated in a signal in the unlicensed radio frequency spectrum band.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of one or more of an input size or an input structure for a transmitting-side neural network, wherein the input structure indicates one or more of non-zero values or locations for the non-zero values within an input, having the input size, to the transmitting-side neural network. The UE may communicate with a base station based at least in part on the indication of the one or more of the input size or the input structure of the transmitting-side neural network. Numerous other aspects are provided.

Abstract: Wireless communications systems and methods related to determining and transmitting delay measurements, such as propagation delay, between a base station (BS) and a user equipment (UE) are provided. In some aspects, a UE may receive, from a BS, a positioning reference signal (PRS). The UE may further transmit, in response to and at a predetermined time after the receiving the PRS, a sounding reference signal (SRS) to the BS. Further, the UE may receive, from the BS, a delay measurement corresponding to the PRS.

Abstract: Aspects relate to carrier aggregation. Selection of an uplink component carrier for carrier aggregation may be flexible in the sense that the frequency band of the uplink component carrier need not be one of the frequency bands allocated for the downlink component carriers. Thus, in some aspects, an uplink component carrier may be decoupled from (e.g., independent of) the downlink carriers. A decision of whether to implement flexible uplink component carrier selection may be based on network traffic (e.g., particular traffic use cases). As one example, the data throughput requirement for downlink traffic may be relatively high, but the component carriers selected for the downlink traffic to provide this throughput might not provide a desired level of service for the uplink traffic. Thus, one or more component carrier bands selected for the uplink traffic may be different from any of the component carrier bands selected for the downlink traffic.

Abstract: The present disclosure relates to methods and devices for wireless communication including an apparatus, e.g., a UE and/or a base station. In one aspect, the apparatus may receive, from a base station, SPS via RRC signaling. The apparatus may also determine a UE Rx-Tx time difference, the UE Rx-Tx time difference being equal to a difference between a downlink subframe reception time and an uplink subframe transmission time. The apparatus may also transmit, to the base station, the UE Rx-Tx time difference or receive, from the base station, a base station Rx-Tx time difference, the base station Rx-Tx time difference being equal to a difference between an uplink subframe reception time and a downlink subframe transmission time.

Abstract: Aspects of the present disclosure provide techniques for physical uplink shared channel transmissions sent using multiple frequency domain resource allocations (FDRAs). According to certain aspects, a user equipment (UE) determines at least a first part frequency domain resource allocation (FDRA) and a second part FDRA, transmits a first part of a physical uplink shared channel (PUSCH) on the first part FDRA with a first precoder, and transmits a second part of the PUSCH on the second part FDRA with a second precoder.
