Abstract: The present disclosure provides a battery cover catch apparatus. The apparatus includes a battery cover, a slide switch, a catch, and a body. A chute which longitudinally extends is provided on the battery cover. The slide switch is disposed on the chute so as to be able to slide between a first position and a second position. The slide switch includes a block located inside the battery cover. The block is connected to the catch so as to drive the catch to slide synchronously. The catch includes a tongue disposed in a same direction as the extending direction of the chute. The body is provided with a recess correspondingly matching to the tongue. The tongue is engaged with the recess when the slide switch is in a first position, and the tongue is separated from the recess when the slide switch is in a second position.

Abstract: A battery lid lock structure comprises: a battery lid (10), a slide switch (20), a lock (30), and a main body (40). A longitudinally extended slide slot (11) is provided on the battery lid (10); the slide switch (20) is mounted on the slide slot (11) and is slidable back and forth between a first position and a second position, and comprises a lock head (21) located in the inner side of the battery lid (10); the lock head (21) and the lock (30) are connected together to drive the lock (30) to slide synchronously; the lock (30) comprises a bolt (31) extended and disposed in the same direction as the slide slot (11); a slot (41) correspondingly matching the bolt (31) is provided on the main body (40); when the slide switch (20) is at the first position, the bolt (31) and the slot (41) are engaged, when the slide switch (20) is at the second position, the bolt (31) and the slot (41) are separated.

Abstract: Embodiments of the present application provide a load balancing method and a network control node. An entity in which a serving cell is located selects a scheduling cell for an edge UE, and instructs the scheduling cell to allocate a data channel for the edge UE, and a control channel is retained in the serving cell and is not handed over. In this way, in a case of being transparent to the UE, an objective of load balancing is achieved by automatic fast coordinating and scheduling without handover. It can be seen that, in the foregoing load balancing manner, a data channel is used as transferring granularity, and a handover time delay does not need to be introduced, thereby implementing a function of fast balancing instantaneous load, and improving load balancing efficiency.

Abstract: A wireless data transmission method is disclosed, in which a transmitter buffers current RLC layer data. The method includes the following steps: the transmitter transmits the current RLC layer data to a receiver; receives a data-receiving packet indicating that the data is incorrectly received, the physical layer of the receiver generated and fed back by the physical layer of the receiver if a physical layer of the receiver determines that the data is incorrectly received; and transmits the buffered current RLC layer data to the receiver. A transmitting system and a receiving system are further disclosed. The method of the present disclosure may enhance the data transmission speed over the RLC layer.

Abstract: The present invention relates to a radio with a key and knob combination. To solve problems such as inconvenience caused by the independent PTT key and volume control knob on the traditional radios, the present invention provides a radio with a key and knob combination, comprising a PPT key unit and a volume control unit, wherein the key is installed inside a central cavity of the knob, which is a hollow knob, to form the key and knob combination. Rotation of the knob (106) may drive the shaft (102) and the toggle piece (111) to rotate synchronously, and then toggle the volume switch (112), while the pressed key (101) may cause the shaft (102) moving axially to toggle the PTT switch (103). When operating the radio with a single hand, users can both press the PTT key to initiate a call and rotate the knob to adjust the volume level by a thumb or a forefinger, and the operation is very convenient.
