The present invention relates to a method for 1 for controlling transmission of data in a data communication network, the transmission of data being a transmission of data between a mining and/or construction machine and a network node of said data communication network, said transmission of data being carried out at least partly over a wireless communication link. The method comprises: —estimating a measure of the communication capacity of said wireless link, the estimation being based at least partly on a round-trip time of a transmission over said wireless communication link, and —adapting the data transmission load of said mining and/or construction machine on the wireless communication link on the basis of said measure. The invention also relates to a system and a mining and/or construction machine.

A method of tracking a user position using a crowd robot, a tag device, and a robot implementing the same are disclosed, and the robot includes a controller, which cumulatively stores position information of a tag device, generates a moving route corresponding to the stored position information of the tag device, and corrects the position information of the tag device based on position estimation information of a crowd robot around the tag device sent from the tag device.

Embodiments of this application provide a communication method and a communications apparatus. The method includes: generating a log record, where the log record is recorded by performing MDT log measurement when a terminal is in an inactive state; and when the terminal is in a connected state, sending the generated log record to a network device.

A method for establishing a wireless connection between a user equipment (UE) device and a base station in unlicensed radio frequency (RF) spectrum includes (a) receiving, at the UE device, a plurality of RF beams broadcasted by the base station, (b) identifying a selected RF beam of the plurality of RF beams having control information with a maximum received signal level, and (c) identifying a first channel occupancy time (COT1) of the base station from control information of the selected RF beam.

User equipment (UEs) within a sidelink communications system may employ control forwarding techniques. For example, a UE may piggyback resource reservation information received from other UEs when broadcasting its own resource reservation. A UE that may be in line of sight (LOS) with two other UEs that themselves are in a non-line of sight (NLOS) situation and may include resource reservation information associated with other UEs when broadcasting the control information. For example, when forwarding control information, a UE may identify additional resources available in a transmission interval, and may convey neighbor control information (e.g., known resource reservations of other UEs in the sidelink communications system) using the additional resources. In some cases, the piggybacked resource reservation information associated with the other UEs may be selected based on the amount of additional resources in the transmission interval, a priority of known resource reservation information, etc.

The various systems and methods disclosed herein provide for a secure, cost effective, and high accuracy location detection. In some implementations of the system and method for high accuracy location detection, a mobile location device obtains and calculates location data from a plurality of sources without requiring expensive and power inefficient processors. In some implementations, such secure, cost effective, and high accuracy location detection by the mobile location device is used in improved vehicle based transactions, such as energy dispensing and payment management systems and methods. In some such implementations, the mobile location device communicates with remote geomapping servers and payment systems to provide automated vehicle based transactions, such as energy dispensing sessions and payment.
