  • Patent number: 11796627
    Abstract: Disclosed are methods and systems for a WLAN device operating on DFS channels to calibrate the PRI as well as delays between partial pulses of received radar pulses that are impaired due to channel and filtering effects. The calibrated PRI may approximate the PRI of the transmitted pulses. The calibrated delay between the partial pulses estimates the interval between two partial pulses that originally belong to the same transmitted pulse. Using the calibrated PRI and the calibrated delay between partial pulses, the WLAN device may reconstruct the original pulses from received impaired pulses even when the impaired pulses are delayed and partial pulses of the original pulses. The WLAN device may use the calibrated results to correct the shortened PW and varying PRI of the impaired pulses to restore the partial pulses to their full PW with a relatively uniform PRI, increasing the probability of detecting the radar signals.

  • Publication number: 20230333242
    Abstract: Some embodiments of the present disclosure provide a manner for sensing devices (UEs) to collaborate with base stations to sense an environment. The UEs may obtain observations based on sensing signals transmitted in the environment and provide the observations to a dedicated processing node. The processing node is configured to process the received observations to coherently combine the observations to generate an enhanced observation. In addition to distributing the sensing to multiple UEs, the processing of the observations may also be distributed.

  • Publication number: 20230318693
    Abstract: Some embodiments of the present disclosure provide a transmit receive point (TRP) with sensing abilities. Through sensing over time, the TRP can obtain details of past locations of a user equipment (UE) and a current location of the UE. Furthermore, the TRP can predict a future location for the UE. Accordingly, the TRP can proactively arrange for switching of beam directions used for both downlink channels and uplink channels. Aspects of the present application relate to a unified physical layer beam switch mechanism for intra-cell mobility and inter-cell mobility. Intra-cell beam switching, wherein a to-be-activated beam is from the same cell as the existing beam, may be triggered by physical layer signaling or media access control signaling. Inter-cell beam switching, wherein a to-be-activated beam is from a different cell than the existing beam, may be triggered by physical layer signaling or media access control signaling.

  • Publication number: 20230309174
    Abstract: Some embodiments of the present disclosure provide proactive beam failure recovery initiation. The proactive initiation may occur at the transmit receive point or at the user equipment. Beam failure, which leads to the beam failure recovery initiation may be proactively detected using sensing or artificial intelligence. A part of any beam failure recovery process is new beam identification. Such new beam identification may be carried out in a traditional manner, using reference signal beam measurement and training. Alternatively, new beam identification may be carried out in a proactive manner, using sensing or artificial intelligence. When indicating a direction for the new beam, a coordinate system may be used. The indicating may reference an absolute beam direction or a differential beam direction by using the coordinate system.

  • Publication number: 20230300813
    Abstract: Some embodiments of the present disclosure provide beam indication solutions. A first solution relates to absolute beam indication and a second solution relates to differential beam indication. Through, for example, information determined using sensing, these beam indication solutions allow for information transfer between transmit receipt point and user equipment to occur on a relatively narrow beam. By reducing scanning, a solution based on beam indication aspects of the present application reduce overhead and, consequently, reduce latency. Another benefit of a narrow beam is improved spectral efficiency. The sensing may allow for a relationship between a beam and an external environment to be established. The relationship allows for a beam to be indicated in a direct and agile manner.

  • Publication number: 20230284139
    Abstract: An air interface is the wireless communications link between two or more communicating devices. An air interface generally includes a number of components that specify how a transmission is to be sent and/or received, e.g. components defining a waveform, a frame structure, a multiple access scheme, a coding scheme, etc. Artificial intelligence (AI) may be implemented in relation to one or more components of the air interface. Therefore, a network may need to accommodate operation for both air interfaces that are not AI enabled and air interfaces that are AI enabled. In some embodiments, methods are provided for switching between different AI modes and a non-AI mode. In some embodiments, a measurement signaling mechanism and related feedback channel configuration is provided so that the same measurement signaling mechanism and related feedback channel may be used regardless of whether a device implements an AI-enabled air interface.

  • Publication number: 20230276249
    Abstract: Restrictions associated with the use of multiple carriers in long-term evolution (LTE) and/or new radio (NR) may impede implementing a flexible personalized spectrum for different user equipments (UEs). Apparatuses, devices, and methods are instead provided in which there is more flexible spectrum utilization, e.g. in which there may be fewer restrictions and more options for configuring carriers and/or bandwidth parts (BWPs) on a UE-specific basis. As one example, in some embodiments, there is not necessarily coupling between carriers, e.g. between uplink and downlink carriers. For example, an uplink carrier and a downlink carrier may be independently indicated so as to allow the uplink carrier and downlink carrier to be independently added, released, modified, activated, deactivated, and/or scheduled.
