Abstract: Multi-User Multiple Input, Multiple Output (MU-MIMO) data transmissions are provided with a forward-predictive precoding matrix to mitigate the effects of a change in a state of a communication channel. First and second soundings are performed, at first and second times, to a receive antenna over a channel and, responsive to each of the soundings, first and second Channel State Information (CSI) are received. Based on the first and second CSI, a change in a state of the channel over a time period between the first and second time is determined. Based on the change in the state of the channel, a forward-predictive channel state matrix and/or a forward-predictive precoding matrix are determined that reflect a state of the channel at a future time and that are consistent with the determined change in the state over the time period. The forward-predictive precoding matrix is applied to a data transmission.

Abstract: A multi-mode switchable car includes a car body, a bogie, a wheel assembly, a steering driving module, a steering locking structure and a locking sensing structure. The car body is provided with a control module, and multiple wheel driving programs are preset. The bogie is rotatably connected to the car body. The wheel assembly includes a hub motor connected to the bogie or the car body and a wheel-type component detachably connected to the hub motor, wheel forms are switchable by connecting different wheel-type components to the hub motor. The steering driving module drives the bogie. The steering locking structure locks the bogie when located in a locking position. The locking sensing structure acquires a position of the steering locking structure and is electrically connected with the control module, and the control module switches the wheel driving programs according to position information acquired by the locking sensing structure.

Abstract: Devices, systems, methods, and non-transitory computer-readable media for modular network architecture. In one embodiment, a server includes a memory and an electronic processor. The memory stores cloud infrastructure definitions, the cloud infrastructure definitions including a plurality of microservices and security groups that define communication between each of the plurality of microservices. The electronic processor is configured to deploy a first virtual private cloud including a first portion of the plurality of microservices and all of the security groups, deploy a second virtual private cloud including a second portion of the plurality of microservices and the all of the security groups, and deploy a third virtual private cloud including a third portion of the plurality of microservices and the all of the security groups.

Abstract: The present invention discloses a distributed base station system as well as its networking method and base band unit. In this system, the base band unit (BBU) and RF unit (RFU) of the base station are separated, and the RFU is equipped with base band RF interfaces for interconnecting the BBU and transmitting data information, thereby forming the base station. Based on the separation of the BBU from the RFU, the BBU capacity is further divided at the same time, and every unit is also arranged independently. The BBU networking and capacity expansion may be achieved with capacity expansion interfaces and base band RF interfaces provided by BBU interface units in flexible and convenient ways.

Abstract: Controlled access is provided to a shared resource 23 such as an ontology (knowledge database) in order to maintain its quality without restraining the ability of users 21a, 21b, 21c . . . to contribute to that resource. An edit and query function 26 is used to determine the validity and consistency of individual contributions. The results of these checks and the level of contribution made by individual users to the information resource is used to produce a rating for each user of the resource, which is stored (24a, 24b . . . ) for use in prioritise and manage future contributions to the resource 23, provide metadata on the resource and to prioritise access control 28 to the resource. When a new contribution is made by a user a threshold of approval can be set before it is accepted into the main database 23. This threshold is based on the sum of the ratings points of the original contributor and of users that give their assent to the inclusion of that contribution.
