  • MOTION-BASED BEAM MANAGEMENT TECHNIQUES IN WIRELESS COMMUNICATIONS
    Publication number: 20230232257
    Abstract: Methods, systems, and devices for wireless communications are described that provide for a user equipment (UE) to detect motion of the UE based on a motion sensor, such as an inertial measurement unit (IMU). The UE, based on the detected motion, may trigger a measurement procedure in which measurements of different beams or cells are performed at a greater periodicity than if the motion were not detected. The indication from the motion sensor may indicate that UE acceleration, rotation, orientation, or any combinations thereof, exceeds a threshold and results in the UE switching to a fastest available measurement periodicity. After triggering the fastest available measurement periodicity, the UE may adjust the measurement periodicity based on newly obtained beam measurements and converge to a measurement periodicity based on observed metrics.

  • Transmission opportunity control method and apparatus
    Patent number: 11683732
    Abstract: In various embodiments, an access point sends a first frame. The first frame carries a TXOP handover enforcement THE indication field which is a first value or a second value. The first value instructs a station that has accessed a channel to hand over a held TXOP to the access point, and the second value instructs the station that has accessed the channel to hand over the held TXOP to the access point when a handover condition is satisfied. It can be learned that the STA hands over the held TXOP to the AP. Therefore, the AP may be a TXOP holder through the TXOP handover even if the AP fails to obtain the channel through contention, so that a probability of holding the TXOP by the AP is improved, a probability of scheduling a STA by the AP is improved, and system resource utilization is improved.

  • Techniques for managing beams using spectral efficiency estimates of two port reference signals
    Patent number: 11658704
    Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a base station and a user equipment (UE) may utilize multi-port reference signals to determine a beam pair for rank-2 transmissions. For example, a UE may receive a set of multi-port reference signals, where each multi-port reference signal of the set corresponds to a unique beam pair and is received via two ports associated with two different polarizations. The UE may determine a spectral efficiency estimation for each multi-port reference signal of the set, select a beam pair associated with a multi-port reference signal with the highest determined spectral efficiency estimation of the set, and transmit an indication of the selected beam pair to the base station. Therefore, the UE and the base station may communicate using a beam pair which maximizes the spectral efficiency and rate of rank-2 transmissions.
