Abstract: A spring adjusting device and a valve assembly including the same. The spring adjusting device includes an adjusting screw rod, a spring, and a spring seat which is located between the adjusting screw rod and the spring. A groove is arranged in the spring seat, which can contain an end part of one end of the adjusting screw rod, and is provided with a cylindrical side wall. The spring adjusting device can prevent the end part of the adjusting screw rod from being separated from the groove, and the spring from being bent on the whole, thereby improving the overall working performance of the valve assembly.

Abstract: This disclosure relates to the mobile communications field, and in particular, to a buffer processing technology in a wireless communications system. In a buffer processing method, user equipment UE triggers a direct link buffer status report, where the direct link buffer status report is at least used to report an amount of buffered data generated by the UE for a first service, and the first service is currently transmitted in a device-to-device (D2D) direct communication mode; and when the UE determines to transmit the first service in a base station relay mode, the UE stops reporting the amount of the buffered data generated by the UE for the first service to a base station. In this way, the UE stops reporting the amount of the buffered data of the first service to the base station when the UE switches from direct link transmission to base station relay transmission.

Abstract: A multicast transmission method is disclosed. A base station of a first cell obtains first multicast resource information of at least one second cell, where the base station of the first cell is different from a base station of each second cell; and the base station of the first cell sends second multicast resource information to user equipment, where the second multicast resource information is used to indicate a resource configuration used by each second cell to transmit multicast service data. The base station of the first cell actively sends obtained multicast resource information to the user equipment in a broadcast manner. In this way, the base station of the first cell does not need to configure, in a unicast manner for each user equipment, a resource location for sending/reading the multicast service data of each second cell, thereby reducing signaling overheads.

In the foregoing solution, the communication path can be selected from the at least two communication paths, to send the message of the V2X service. In this way, a communication path is flexibly selected for a V2X service.

Abstract: Embodiments of the present invention propose a D2D communications method, apparatus, and system. In the solution, a D2D SPS available period in which a first terminal is capable of using a D2D SPS resource is greater than one SC period. Therefore, in the D2D SPS available period, the first terminal needs to determine the D2D SPS resource only one time, and a second terminal also needs to decode SCI only one time to determine the D2D SPS resource. In this way, the first terminal does not need to determine a D2D SPS resource in each SC period, and the second terminal also does not need to decode SCI in each SC period to determine the D2D SPS resource. Therefore, D2D communication efficiency is improved.

Abstract: Embodiments of the present invention provide a data transmission method and apparatus, and relate to the communications field. The method includes: obtaining configuration information; establishing at least one logical channel according to an identifier of each logical channel and the corresponding transmission mode indication; obtaining a transmission resource according to the transmission mode indication of a logical channel to which device-to-device (D2D) buffered data belongs; and sending the D2D buffered data by using the obtained transmission resource. A problem that a resource allocation mode used by a terminal during D2D communication is relatively single and is not flexible enough is resolved, and the terminal can use different resource allocation modes according to a logical channel granularity, so that not only consumption of signaling resources of a network device can be reduced, but also QoS requirements of some services that require relatively high QoS can be satisfied.

Abstract: A system optimizes performance of parallel queries by dividing a query into a plurality of sub queries. The query is divided according to a plurality of data ranges associated with the query. The system creates an available queue, and a defer queue. The system assigns the plurality of sub queries into the available queue. The system then processes, in parallel, the plurality of sub queries in the available queue. During the processing, if the system determines that a data range associated with a sub query comprises unavailable data, the system assigns the sub query to the defer queue as a defer range sub query. After completing the processing of the plurality of sub queries in the available queue, the system processes a plurality of defer range sub queries in the defer queue.
