摘要： The present invention relates to a ball picking robot, comprising a walking mechanism, a ball picking mechanism, a ball pushing mechanism and a ball storage mechanism. The ball picking mechanism comprises a ball picking basket, an air cylinder used for driving the ball picking basket to move up and down, an air storage tank used for providing an air source for the air cylinder, a solenoid valve arranged at the air outlet of the air storage tank, a micro air pump connected to the air storage tank, and a shielding assembly arranged at an opening in the rear end of the ball picking basket. A first gear is mounted at the input end of the micro air pump. The ball pushing mechanism comprises a rotary ball discharging assembly, comprising an either-rotation motor, a rotary impeller connected to a first output shaft of the either-rotation motor through a belt assembly.

摘要： The invention relates to a double-sided drilling fixture for die-forged pistons and a double-sided drilling process thereof. It overcomes the defects of low efficiency and accuracy of the double-sided drilling operation for die-forged pistons in the prior art. The invention comprises a die-forged piston, a fixture base assembly, an upper load-resisting assembly and a lower expansion-resisting assembly. The upper load-resisting assembly is installed on the fixture base assembly and disposed above the die-forged piston. A fixation base, whose upper surface shape is the same as internal surface shape of the die-forged piston, is installed above the fixture base assembly. The die-forged piston is sleeved on the fixation base. The invention achieves simultaneous drilling on both sides of the two rear skirt surfaces of die-forged pistons and delivers quick clamping and automatic fixation, significantly reducing the difficulty in the assembly of drilling plate and workpiece and increasing the alignment accuracy.

摘要： Aspects of the present disclosure relate to techniques for non-codebook based uplink (UL) transmission. In some cases, a user equipment (UE) may signal, to a network entity, capability information of the UE for non-codebook uplink transmissions. The UE may then receive, signaling, from the network entity, indicating a plurality of sounding reference signal (SRS) configurations based at least on the signaled capability information, wherein at least one configuration indicates at least one SRS resource and determine a plurality of precoding candidates, wherein each precoding candidate is associated with a configured SRS resource. The UE may then transmit the SRSs using the associated precoding candidates.

摘要： Certain aspects of the present disclosure relate to communication systems, and more particularly, to a partial channel state information reference signal (CSI-RS) port indication. A method by a base station (BS) includes configuring a user equipment (UE) with a CSI-RS resource, of one or more CSI-RS resources associated with a CSI report. The CSI-RS includes a set of CSI-RS ports. The BS provides a first indication to the UE of a subset of groups of the CSI-RS ports to be used by the UE for channel measurements and/or a second indication to the UE of a subset of groups of the CSI-RS to be used by the UE for interference measurements. Based on the indication, the UE performs channel measurements and/or interference measurements using the indicated subset of CSI-RS ports.

摘要： A method, an apparatus, and a computer program product for wireless communication are provided in which a signal including a signal from a UE is received. System information of a neighboring eNodeB is obtained. The received signal is processed based on the system information in order to enhance the received signal with respect to the signal from the UE.

摘要： Certain aspects of the present disclosure provide techniques for implicitly linking aperiodic channel state information (A-CSI) reports to CSI-reference signal (CSI-RS) resources. In an aspect, the UE may be instructed to report on specific CSI-RS resource(s) via explicit signaling in the UE grant. Other aspects disclose techniques for implicit CSI-RS resource selection by the UE that require fewer signaling resources. Instead of explicitly signaling CSI-RS resources to the UE, the UE may implicitly select CSI-RS resource for CSI feedback reporting based on information known to the UE, e.g. a subframe on which a reporting request is received. This may reduce the impact of the additional signaling in the UE grant.

摘要： A method for transmitting an acknowledgement/negative acknowledgement is described. Cell-specific symbol-level cyclic shift hopping is applied to data single-carrier frequency division multiplexing symbols of the acknowledgement/negative acknowledgement. A discrete Fourier transform is applied to the data single-carrier frequency division multiplexing symbols. Cell-specific symbol-level phase hopping is applied to the data single-carrier frequency division multiplexing symbols. The data single-carrier frequency division multiplexing symbols are transmitted in a slot.
