  • Patent number: 12641453
    Abstract: This disclosure provides systems, methods and apparatuses for measurement of cells and determination of a non-standalone (NSA) coverage status using an NSA coverage database. The NSA coverage database may indicate candidate frequencies of New Radio (NR) cells that provide NSA coverage corresponding to a given Long Term Evolution (LTE) serving cell. The NSA coverage database may also indicate whether a system information block 1 (SIB1) has been previously received on a candidate frequency. The user equipment (UE) may perform measurement of candidate frequencies using the NSA coverage database, and may identify cases where a cell not providing NSA coverage has a same candidate frequency as a cell providing NSA coverage using the indication of whether SIB1 has been previously received on a candidate frequency.

  • Publication number: 20260018494
    Abstract: In a chip stacking structure, a third die, a second die, and a first die are sequentially stacked on a carrier board. A first redistribution layer and a first interface component of the first die form a first interface circuit, and a second redistribution layer and a second interface component of the second die form a second interface circuit. A first conductive structure penetrates through at least the second die and the third die, and a second conductive structure penetrates through at least the third die. The first interface circuit of the first die and the second interface circuit of the second die are separately electrically connected to another component through the insulated first conductive structure and the insulated second conductive structure.

  • Patent number: 11217932
    Abstract: Disclosed in the present disclosure is an electromagnetic compatibility type cable locking joint. The electromagnetic compatibility type cable locking joint comprises a joint main body, a joint cap, a sealing ring, and a shielding member. The joint main body has a central hole, and an inner step is provided in the central hole. The sealing ring is connected to the end of the joint main body, and a positioning groove is formed between the sealing ring and the inner step. The joint cap is connected to the sealing ring, the shielding member comprises an upper ring, a lower ring, and an arc-shaped elastic piece. A plurality of arc-shaped elastic pieces are uniformly arranged in a circle. The upper end of each arc-shaped elastic piece is formed on the upper ring, and the lower end of each arc-shaped elastic piece is formed on the lower ring.
