摘要： Coverage enhancements and coverage mode switching related optimizations are discussed for user equipments (UEs) that may switch between various coverage extension (CE) and non-CE modes of operation. In such enhancements, paging uncertainty and delays may be reduced by sending pages either simultaneously or using historical information over multiple coverage modes available to UEs. Random access procedures may be improved by providing CE mode random access procedures that are available when normal mode random access attempts fail and before declaring radio link failure. Additional aspects include improvements for more advanced UEs to improve coverage within normal mode operations by leveraging techniques used for narrowband CE mode operations, including transmission repetition and gapless transmission scheduling over hopped narrowband frequencies.

摘要： The disclosure provides for a user equipment (UE) detecting an indication of an application-specific latency reduction triggering condition that may trigger switching of a communication state of the UE. For example, the UE may be in an initial state. The UE may transition into a different state that is associated with lower latency for data transfer. In an aspect, the UE may trigger the indication for latency reduction even when the network-configured criteria for the indication has not yet been met. The UE may trigger an application-specific latency reduction triggering condition during the startup of an application, which triggers a resource request message even before the network-configured threshold value for generating such resource request messages is satisfied. The resource request message may cause the network to command the UE to transition to a state that has a latency less than that in the current state.

摘要： Embodiments described herein can address these and other issues by using radar machine learning to address the radio frequency (RF) to perform object identification, including facial recognition. In particular, embodiments may obtain IQ samples by transmitting and receiving a plurality of data packets with a respective plurality of transmitter antenna elements and receiver antenna elements. I/Q samples indicative of a channel impulse responses of an identification region obtained from the transmission and reception of the plurality of data packets may then be used to identify, with an autoencoder, a physical object in the identification region.

摘要： In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus operates in a first power mode with a first DL bandwidth in association with one of a radio resource control (RRC) idle state or an RRC connected state with a base station. The apparatus sets an inactivity timer and resets the inactivity timer upon receiving a DL assignment or an uplink grant. The apparatus transitions to a second power mode with a second DL bandwidth less than the first DL bandwidth upon expiration of the inactivity timer. Additionally, the apparatus monitors a set of symbols and a set of subcarriers of the second DL bandwidth for an activity indicator from the base station. The apparatus transitions from the second power mode to the first power mode upon receiving the activity indicator from the base station.

摘要： Techniques provided herein are directed toward enabling short-range proximity detection using radar sensors by reducing or eliminating OTA leakage. Embodiments generally include performing spatial cancellation by using a plurality of transmit/receive pairs of antenna elements to implement analog and/or digital leakage cancellation on the transmit and/or receive side. According to some embodiments null space projection cancellation, OTA leakage tracking, or adaptive minimum variance distortionless response (MVDR) beamforming may be performed to help preserve of the OTA leakage cancellation efficacy over time.

摘要： A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus begins to transmit a data packet and control information. Upon receiving an Ack of early decoding of the data packet prior to transmission of the entire data packet, the apparatus ceases transmission of the data packet, yet continues to transmit at least a portion of the control information. Transmission of the portion of the control information that is only needed to decode the data packet is ceased. Transmission of the residual portion of the control information ceases once its use ends. A receiving apparatus begins to receive the data packet and control information. After early decoding the packet, the apparatus transmits an Ack of early decoding and powers down a decoding module. Upon receiving a second Ack, the apparatus ceases to monitor the control information.

摘要： A UE may establish a communications link with a base station. The UE may determine at least two radio network temporary identifiers (RNTIs) associated with the communications link, wherein each of the at least two RNTIs is associated with a respective relay device of a plurality of relay devices. The UE may receive, from a first relay device of the plurality of relay devices, at least one first stream associated with a first RNTI of the at least two RNTIs, wherein the at least one first stream carries data or control information associated with the communications link. The UE may receive, from a second relay device of the plurality of relay devices, at least one second stream associated with a second RNTI of the at least two RNTIs, wherein the at least one second stream carries data or control information associated with the communications link.

The apparatus operates in a first power mode with a first DL bandwidth in association with one of a radio resource control (RRC) idle state or an RRC connected state with a base station. The apparatus transitions to a second power mode with a second DL bandwidth less than the first DL bandwidth. Additionally, the apparatus monitors a set of symbols and a set of subcarriers of the second DL bandwidth for an activity indicator from the base station. The apparatus transitions from the second power mode to the first power mode upon receiving the activity indicator from the base station. In an aspect, control information associated with a modulation scheme may be within the set of symbols and the set of subcarriers. The control information may correspond to a particular constellation point.
