Abstract: The present disclosure provides a method and device for multicast transmission, wherein a method for multicast transmission performed by a first network device includes: receiving a first message for requesting handover from a second network device; transmitting a second message for responding to the first message to the second network device.

Abstract: An electronic device may be provided with wireless circuitry and control circuitry. The wireless circuitry may include a phased antenna array. Sensors and other circuitry in the electronic device may generate sensor data such as accelerometer data, gyroscope data, magnetometer data, location data, and spatial ranging data. The wireless circuitry may establish and maintain one or more wireless links with external devices based on the sensor data as the device moves over time. For example, the wireless circuitry may perform physical layer beam adjustments, inter-radio access technology handovers, intra-radio access technology handovers, and/or dual connectivity adjustments based on the sensor data. This may allow the device to maintain one or more wireless links without having to sweep the signal beam of the phased antenna array over its entire field of view each time the device has moved.

Abstract: Disclosed are techniques related to wireless communication system to enable full duplex communication. A network node may include a transceiver, a memory, and a processor communicatively coupled to the transceiver and the memory. The transceiver, memory, and processor may be configured to determine downlink (DL) parent and child link priorities for parent and child time-domain resources that overlap in time at least partially. The transceiver, memory, and processor may also be configured to determine DL parent and child beams based on the DL parent and child link priorities. The transceiver, memory, and processor may further be configured to notify the parent node of the DL parent beam for the parent and child time-domain resources. The transceiver, memory, and processor may yet further be configured to concurrently receive parent traffic from the parent node using the DL parent beam and transmit child traffic to the child node using the DL child beam.

Abstract: Methods, systems, and apparatuses are described herein for beamforming based initial access, beam management, and beam based mobility designs for NR systems. Issues are identified and addressed related to one or more of initial access, control channel design, eMBB and URLLC mixing, and beam training. The methods, systems and apparatus may include a receiving scheduling information and a preemption indication via a DCI. In addition, there may be a detecting and decoding of the preemption indication, a determining of a HARQ feedback associated, and a sending, to a network node, of the HARQ feedback.

Abstract: Provided are a head-mounted device and a method for controlling a head-mounted device. The head-mounted device includes an adjustment assembly. The adjustment assembly includes an adjustment push block, a driving apparatus and an adjustment gear. Two adjustment push blocks are provided. One of the device host and the at least one of the device legs is provided with a fixed seat, and the other of the device host and the at least one of the device legs is provided with a movable seat, and each of the two adjustment push blocks is slidably disposed on the fixed seat. The adjustment gear is disposed at an output end of the driving apparatus, is located between the two adjustment push blocks, and is meshed with the two adjustment push blocks, and the two adjustment push blocks are configured to drive the device legs to rotate in opposite directions.
