Abstract: A wireless device may receive a first synchronization signal block (SSB) in a radio frequency band of a first cell of a neighbor base station, and report a physical cell identifier (PCI) for the first cell to a serving base station. The serving base station may identify, based on the PCI report, whether a radio frequency band of the first SSB is in or off a synchronization raster, and determine whether to instruct the UE to report a global cell identifier (CGI) for the neighbor base station (e.g., CGI for the neighbor cell) based on the identification. The wireless device may identify CGI based system information obtained from the neighbor cell, system information obtained from a master cell associated with the neighbor base station, system information obtained from CGI broadcast from the neighbor cell, or system information requested from the neighbor cell using dedicated resources, based on the instruction.

Abstract: A user equipment (UE) may initiate a random access (RACH) procedure using an uplink resource selected based on a corresponding received synchronization signal block. The UE may detect a random access procedure trigger. The UE may configure a selection threshold time. The selection threshold time may be based at least in part on a latency requirement of the UE. The UE may select a synchronization signal block having a corresponding uplink resource within the selection threshold time. The synchronization signal block and corresponding uplink resource satisfy one or more parameters or conditions. The UE may transmit a random access preamble on the corresponding uplink resource.

Abstract: A grouped photography studio lighting system with software-driven and simultaneous wireless dimming control comprises a wireless remote controller, a computer and several studio lights. The computer includes a software for controlling the wireless remote controller to transmit wireless signal. Each studio light has a receiver for receiving the wireless signal and lights an object according to the wireless signal. The wireless remote controller can switch on or increase a parameter of some studio lights and switch off or decrease the parameter of other studio lights simultaneously when a control mark is under a planar control. The grouped photography studio lighting system can further be used with a photography device and/or a sensor. The photography device is controlled by the computer via a wire or wireless signal. The sensor connects the computer via a wire or wireless signal, and each studio light is controlled according to the sensor detection.

Abstract: A system and methods for estimating a noise power level in an uplink signal for a virtual MIMO system is disclosed. The system comprises a demodulation reference signal (DMRS) module configured to obtain a DMRS receive symbol from the uplink signal and determine a DMRS sequence for a first UE in the virtual MIMO system. An autocorrelation module is configured to calculate an average autocorrelation value for the subcarriers in the uplink signal. A cross-correlation module is configured to calculate first and second cross-correlation values of the uplink signal Rz (l) for values of l selected such that the sum of the received power from the first UE and the second UE can be accurately estimated. A noise power level module is configured to determine the noise power level for the uplink signal using the average autocorrelation value and the first and second cross correlation values.

Abstract: A device for extending and controlling signals of a camera shutter release cable through an isolated switch is provided. A single short signal is generated to a camera shutter release cable by a manual button, another control device or a computer command, and extended into a multiple short signal with well isolation, good stability and enough voltage level through multiple isolated switches, so as to simultaneously activate several cameras connected in parallel to focus and snap. Therefore, it is able to prevent that the voltage levels provided by a single short signal are too low to simultaneously activate all of those cameras connected from the interference between them. Moreover, the foregoing multiple short signal can further be individually, partially or together controlled by a computer, a USB and a CPU, so as to simultaneously activate the cameras connected in parallel to focus and snap rapidly.

The phase detection module receives an IF signal, and detects a sine and a cosine signals corresponding to the IF signal.

The phase angle adjustment module adjusts the phase angle according to one of the sine and the cosine signals and a threshold. The loop filter generates a frequency offset angle according to the phase angle. The conversion module generates a sine and a cosine parameters according to the frequency offset angle, and transfers the sine and the cosine parameters to the phase detection module.
