Abstract: This application discloses a method used to remove a target blockchain node group of a first tenant from a channel. In the method, an execution node of a second tenant receives configuration information of the target blockchain node group of the first tenant which is sent by a management node, obtains channel configuration information of the channel from a consensus organization, and generates channel adjustment information based on the channel configuration information and the configuration information of the target blockchain node group. The execution node of the second tenant sends the channel adjustment information to the consensus organization, and the consensus organization generates a block including the channel adjustment information. A blockchain node group of the second tenant obtains the block from the consensus organization, and adds the block to a blockchain stored in the second tenant.

Abstract: This document describes techniques and systems of a radar system with an angle-finding process for sparse uniform arrays. The described radar system includes a processor and an antenna that can receive electromagnetic energy reflected by objects in the surrounding environment. The antenna includes a one-dimensional (1D) or two-dimensional (2D) sparse array. The processor can determine, using the received electromagnetic energy, a signal subspace associated with the objects that includes an invariance equation. Using an estimated solution to the invariance equation, the processor determines a solution to the invariance equation. The solution to the invariance equation is used to determine angular phases associated with the objects. The processor can then determine, using the angular phases, angles associated with the objects. In this way, the described angle-finding process enables the radar system with a sparse array to efficiently determine angles associated with objects without blind spots.

Abstract: There are proposed methods, devices, and computer program products for prediction model management. In the method, gradient information associated with the prediction model is obtained based on sample data for a time slot in a predetermined time period. An offset of the time slot in the predetermined time period is acquired. A step size is determined for updating a parameter of the prediction model based on the gradient information, the offset, and historical gradient information that is determined based on historical sample data for a group of historical time slots before the time slot. With these implementations, the whole training procedure may be divided into multiple time period and each time period may further include multiple time slots. During each time period, the offset may be used to control the importance of the historical gradient information and the gradient information in determining the step size.

Generally, the described techniques provide for enhanced performance of an uplink control channel such as a physical uplink control channel (PUCCH) through the use of transmission diversity.

According to some aspects, a transmit diversity scheme may be employed at the RE level through application of different spatial precoders for different groups of REs of a given RB.
