    摘要： Apparatuses, systems, and methods for a wireless device to perform methods to implement mechanisms for a UE to request a beam quality measurement procedure. A user equipment device may be configured to perform a method including performing transmitting a request to perform a beam quality measurement procedure for downlink receptions (e.g., a P3 procedure) to a base station/network entity, receiving instructions to perform the beam quality measurement procedure from the base station, and transmitting results of the beam quality measurement procedure to the base station. In some embodiments, transmission of the request may be response to at least one trigger condition and/or detection of a condition at the UE. The request may include an indication of a preferred timing offset. The instructions to perform the beam quality measurement procedure may include a schedule for the beam quality measurement.

    摘要： An interface circuit in a recipient electronic device (such as a cellular telephone) may provide preference-indication information for an electronic device (such as an access point). Notably, the recipient electronic device may compute preference-indication information associated with the recipient electronic device, where the preference-indication information indicates whether the recipient electronic device prefers that the electronic device use downlink (DL) multi-user (MU) MIMO transmissions when communicating with the recipient electronic device. Then, the recipient electronic device may provide the preference-indication information in a packet or a frame associated with the electronic device. In some embodiments, the recipient electronic device determines a trigger event (such as measuring a motion indication), and the computing may be selectively performed based at least in part on the trigger event. Moreover, the preference-indication information may include additional information that was used by the recipient electronic device to compute the preference indication of the recipient electronic device.

    摘要： An enhanced listen-before-talk procedure may be performed by a device for efficiently accessing and utilizing available resources. The procedure may include specifying input parameter values pertaining to intended wireless communications of the device, adjusting output parameter values based on the input parameter values and an access history of the device, and determining whether to access at least a portion of the wireless communication resources to conduct the wireless communications, based at least on the output parameter values. The output parameter values may pertain to wireless communication resources accessible to the device, and the access history may keep track of wireless communication resource accesses previously made by the device. Input parameter values may include requested channel occupation time, requested frequency resource, requested transmission power, and/or priority and/or urgency of requested transmission, while output parameter values may include energy detection threshold, contention window size, and/or extended clear channel assessment bypass.
