An interference measurement method includes receiving, by a receiving side, a signal. The signal includes a second pilot sent by an interference sending side, and the interference sending side is an interference source when the receiving side performs receiving measurement on a first pilot of a sending side; and performing, by the receiving side, interference measurement on the interference sending side. The interference measurement includes measurement of the second pilot, and both the receiving side and the sending side use an OTFS system.

An electrical connector comprises an insulative housing, a printed circuit board retained in the insulative housing, and a limiting member. The insulative housing has a mating portion and a main portion extending backwards from the mating portion. The printed circuit board has a tongue portion exposed in front of the mating portion and a plurality of golden fingers disposed on the tongue portion for mating with a complementary connector. The limiting member defines a pair of first limiting plates parallel and opposite to each other. The first limiting plates are located in front of the mating portion entirely and on both sides of the tongue portion in a transverse direction, a first guiding slot is formed between each first limiting plate and corresponding lateral surface of the tongue portion in the transverse direction for leading the complementary connector to be plugged.

A service virtual machine provides service to any number of virtual machines on a hypervisor over a first communication channel. When an anomaly is detected within the provided service, any virtual machine using the first communication channel switches to a second communication channel and receives service from a second virtual machine. The second virtual machine may execute upon the same computer or on a different computer. Hooking points within the hypervisor provide a means for the service virtual machines to monitor traffic and provide service to the protected virtual machines. When a service virtual machine is suspended, it is repopulated, upgraded or rebooted, and then restored to service. Once restored, any protected virtual machine may be switched back to the restored service virtual machine. Virtual machines may be switched to a different communication channel by modifying a configuration file. Both communication channels may be in use at the same time.

The present invention provides a method of providing feedback information in a user equipment of a communication system based on MIMO, comprising: determining a first latest measured long-term covariance matrix according to a downlink channel matrix model; transmitting the quantization of a first latest estimated long-term covariance matrix corresponding to the first latest measured long-term covariance matrix to the base station; determining a second latest measured long-term covariance matrix according to a downlink channel matrix model; determining the variation information of a second latest estimated long-term covariance matrix with respect to an estimated long-term covariance matrix of the last-time reset point; and transmitting the quantization of the variation information to the base station. With such a solution, overhead during the feedback of long-term covariance matrix is greatly reduced in MIMO scenario.

A fixing structure for fixing a display panel is disclosed. The fixing structure includes a bezel and a cover. The bezel includes a frame, a first bending portion bent from a side of the frame, and a first hooking portion connected to an end of the first bending portion. The cover and the bezel cover the display panel together. The cover includes a board, a first curved portion bent from a side of the board, and a first hook component connected to an end of the first curved portion and installed inside the frame and the first bending portion. The first hook component engages with the first hooking portion and fixes a side of the display panel on the side of the first curved portion as the bezel combines with the cover.
