  • Publication number: 20230027103
    Abstract: Methods, systems, and devices for wireless communications are described. In some communications systems, interference may impede signaling between a base station and a target user equipment (UE) such that a base station may identify a donor UE to relay communications to the target UE. The donor UE may receive a coded data packet from the base station, and may identify a radio network temporary identifier (RNTI) scrambling code for the packets addressed to the target UE. In cases where the donor UE identifies that the packet has an RNTI scrambling code associated with the target UE, the donor UE may forward the coded data packet to the target UE base on the RNTI scrambling code. Such early detection of data packets addressed to the target UE may allow for the UE to forward a data packet without fully decoding the packet.

  • Publication number: 20230013691
    Abstract: A cell handover method is disclosed. A terminal obtains a signal attenuation observation instruction, detects, in response to the signal attenuation observation instruction, signal strength and a signal attenuation parameter of a first cell, and sends the signal strength and the signal attenuation parameter to a network side device. Then, the network side device determines, based on the signal strength and the signal attenuation parameter, whether a cell handover is to be performed by the terminal. After performing a cell handover for the terminal is determined, the terminal is triggered to perform the cell handover from the first cell to a second cell.

  • Patent number: 11556356
    Abstract: A call to an external interface to execute a target callee program associated with a first addressing mode in a secondary runtime environment (RTE) is received from a caller program associated with a second addressing mode running in a primary RTE. An address of a share area (SA) storing existing dynamic link object information in the primary RTE in storage is passed to the secondary RTE. The SA is accessible by both the caller program and the target callee program. In response to a request to load a dynamic link object by an initiating program during execution of the target callee program in the secondary RTE, an entry address of the dynamic link object is retrieved in the SA. The dynamic link object is loaded based on the retrieved entry address of the dynamic link object.

  • Publication number: 20230000983
    Abstract: The syntheses of two phosphoramidite building blocks based on BNSF and BNSMB structures are disclosed. Furthermore, some common molecular intermediates have been designed and linked to the central biphenyl core of the two molecules, resulting in a versatile and cost-effective design. These compounds can be effectively introduced to DNA oligonucleotides via the well-established standard cyanoethylphosphoramidite chemistry on the nucleic acid synthesizer. Fragmentation of these BNSF- and BNSMB-functionalized DNA strands is achieved by both one-photon and two-photon photolysis of photoliable bonds of [2-(2-nitrophenyl)propoxy]carbonyl groups on BNSF and BNSMB molecules respectively, resulting in two short pieces of single-stranded DNAs.
