Abstract: Present implementations are directed to simultaneous uplink transmissions based on multi-TRP operation. In some arrangements, a wireless communication method includes receiving, by a wireless communication device, a first downlink signaling that is associated with a second downlink signaling, and simultaneously transmitting, by the wireless communication device, a first uplink transmission and a second uplink transmission that are scheduled by the first downlink signaling and the second downlink signaling, respectively.

Abstract: The invention provides a neural electrode, including a current generation device, a first and a second electrode. The current generation device is connected to the first and second electrodes through a conductive metal wire respectively. At least one of the first and second electrodes is a graphene electrode. The graphene electrode has soft texture and desirable stability to tolerate the repeated pressing and folding treatment, very high charge injection efficiency, and desirable in vivo stability, and is configured to electrically stimulate tissues and organs such as hearts and nerves to promote electrical stimulation and repair of neurons, to further promote regeneration of neural functions. The invention further provides use of a mineralized three-dimensional porous graphene foam material to prepare a bone defect filler. The bone defect filler has desirable biological compatibility, promotes cell proliferation, and accelerates and induces osteogenic differentiation of bone marrow mesenchymal stem cells.

Abstract: An address competition method of a multi-connected type control system. The method aims at solving the problem of how to set an indoor machine communication address in the multi-connected type air conditioner system efficiently. For the purpose, a primary control device (such as an air conditioner outdoor machine) performs broadcasting on each address in a preset address section in sequence. A slave control device (such as the air conditioner indoor machine) responds to the primary control device on the basis of preset responding time and the number of currently broadcasting times of the primary control device. The primary control device to which a communication address is distributed temporarily is responded so as to finish address competition rapidly. Meanwhile, the primary control device can perform continuous broadcasting on one address for repeatedly, so that the competition success rate of the address is increased.
