Abstract: Apparatuses and methods for obtaining and providing hybrid automatic repeat request acknowledgement (HARQ-ACK) information. A method for providing HARQ-ACK information includes receiving a configuration for a slot offset value and receiving a physical sidelink shared channel (PSSCH) over a number of sub-channels in a first slot. The PSSCH includes a transport block (TB). The method includes determining a second slot as an earliest slot with resources for transmission of a physical sidelink feedback channel (PSFCH) that is after the first slot by a number of slots equal to the slot offset value. The PSFCH includes the HARQ-ACK information that is in response to reception of the TB. The method further includes transmitting the PSFCH in the second slot.

Abstract: A method for a user equipment (UE) to provide hybrid automatic repeat request acknowledgement (HARQ-ACK) information includes transmitting physical sidelink shared channels (PSSCHs), where each of the PSSCH transmissions provides a transport block (TB); receiving physical sidelink feedback channels (PSFCHs); and generating values for HARQ-ACK information bits from the PSFCH receptions. The PSFCH receptions correspond to the PSSCH transmissions and the values of the HARQ-ACK information bits correspond to the TBs in the PSSCH transmissions. The method further includes generating a HARQ-ACK codeword that includes the values of the HARQ-ACK information bits arranged in a predetermined order and transmitting the HARQ-ACK codeword in a physical uplink control channel (PUCCH).

Abstract: A readable storage medium, a bone modeling registration system and an orthopedic surgical system are provided. The readable storage medium stores thereon a program, which, when executed, acquires image information of a bone surface of a target object from a stereoscopic vision scanner; creates a first virtual bone model by 3D reconstruction according to the image information of the bone surface; registers the first virtual bone model to a pre-stored second virtual bone model of the target object, and obtains coordinates of the target object in a navigation image coordinate system based on position and posture information of the stereoscopic vision scanner. With this arrangement, a need to place a fiducial marker on the bone is dispensed with, avoiding secondary damage caused to a patient, reducing contact between surgical instruments with the patient's body and the chance of contamination and facilitating cleaning of the instruments.

Abstract: A method for correcting position of an osteotomy guide tool is disclosed. A trackable element mounted on the osteotomy guide tool or on the robotic arm tracks the position of the osteotomy guide tool and generates position information of the trackable element. According to the current position and the desired position of the trackable element, a robotic arm drives the osteotomy guide tool and the trackable element to move, until the trackable element is moved to the desired position. This method does not need to consider the absolute position accuracy of the robotic arm, and does not rely on the experience of the surgeon. The tool has several guiding features, which can provide guides for osteotomy operations, so that the same osteotomy guide tool can perform multiple operations of osteotomy and punching, thus greatly reducing the operation time and improving the operation efficiency.
