摘要： Techniques described here related to a power headroom power headroom report generation trigger. One aspect of the disclosure includes a user equipment (UE) configured to measure a first path loss change of a first physical uplink shared channel (PUSCH) transmission transmitting from the first antenna panel to a first transmission and reception point (TRP). The UE can further measure a second path loss change of a second PUSCH transmission transmitting from the second antenna panel to a second TRP, the second PUSCH transmission transmitting simultaneously to the first PUSCH transmission. The UE can further determine whether to generate a powerhead report (PHR) based on the measured first path loss change and measured second path loss change. The UE can further generate the PHR based on the determination.

摘要： Devices, systems and methods are provided to improve pairing between first and second devices to mitigate risk that either device pairs with an unintended device by reducing transmit power to limit communication range between devices to be paired, using minimum and maximum received signal strength thresholds to reject unintended devices, and instructing user to move to another location when multiple devices are detected for pairing. The second device scanning time for detecting advertising signals from the first device is adjusted to detect multiple device co-existence. Pairing is controlled to occur when the second device is the only device that the first device detects.

摘要： In a 5G or 6G wireless network, the base station can assist user devices in aligning their beams toward the base station, and can align downlink beams toward each of the user devices, by exchanging brief test signals followed by brief encoded feedback messages. The test signals may be transmitted in different directions, or with different beam widths, or with other transmission parameters, thereby enabling the user device to select the best version and reply accordingly. In addition, the user device can determine, from information in a message accompanying the test signals, a direction or angle of each test signal, and thereby determine the correct direction toward the base station by adding 180 degrees, without further experimentation. For compact messaging, a zero-power state may be included in the modulation scheme, thereby providing an efficient format for selecting which beam or which direction is best received.

摘要： Apparatuses, systems, and methods for a user equipment device (UE) to determine a default beam for a dedicated PUCCH/SRS in a CC. The UE may determine a pathloss RS has been configured in the CC, e.g., responsive to the UE determining that spatial relationship information for a default transmission beam has not been configured and determine the default beam for transmissions based, at least in part, on the (configured) pathloss RS. Additionally, responsive to determining that the pathloss RS has not been configured in the CC, the UE may determine that no CORESETs/TCI states for a PDSCH in the CC have been configured and determine the default beam for transmissions based, at least in part, on a default transmission beam in another CC, a CC index, a PRACH procedure; a PUSCH transmission; an SRS transmission, and/or a PUCCH transmission.

摘要： A control method for controlling a connection destination of a station in a network is provided. In the control method, information is obtained regarding transmission power at a first access point in the network. The first access point performs communication complying with an IEEE802.11 standard and is in communication with a station which is connected to the first access point. Control processing is executed for controlling the first access point and a second access point that performs communication complying with the IEEE802.11 standard. The control processing is performed such that, on a basis that the transmission power is higher than a first predetermined value, the connection destination of the station is changed from the first access point to the second access point.

摘要： A base station transmits a first transmission using a first directional beam and determines an equivalent isotropic radiated power (EIRP) relationship between the first transmission and a physical downlink shared channel (PDSCH) for a user equipment (UE). The base station transmits, to the UE, an indication of the EIRP relationship between the first transmission and the PDSCH. Then, the base station transmits the PDSCH to the UE using the second directional beam. The UE uses the indication of the EIRP relationship to receive the PDSCH from the base station over the second directional beam.
