Abstract: A wireless communication method employed by an access point (AP) includes: negotiating with another AP for setting up a coordinated service period (SP), and sending a first announcement frame inside a first basic service set (BSS) to inform that the coordinated SP has been created. The step of negotiating with the another AP for setting up the coordinated SP includes: receiving a request frame from the another AP, wherein the request frame includes a plurality of SP parameters; and sending a response frame to the another AP. The AP belongs to the first BSS, and the another AP belongs to a second BSS different from the first BSS.

Abstract: The present invention provides a multiplication-accumulation circuit including a switched capacitor module, a buffer and a voltage-to-delay converter. The switched capacitor is controlled by an input signal to receive a ramp signal to generate a voltage signal. The buffer is configured to receive the voltage signal to generate a buffered signal. The voltage-to-delay converter is configured to convert the buffered signal to an output delay signal having delay time information.

Abstract: A down-converted voltage regulator is provided. The first energy storage element provides a pre-charged voltage between a connection terminal and a ground terminal during the first phase. The second energy storage element has a first terminal, and it has a second terminal coupled to the output terminal of the voltage regulator. The third energy storage element is coupled between the output terminal of the voltage regulator and the ground terminal. During the first phase, the first terminal of the second energy storage element is coupled to the first energy storage element through the connection terminal to receive the pre-charged voltage. During the second phase, the first energy storage element is coupled between the input terminal and the output terminal of the voltage regulator to be pre-charged to store the pre-charged voltage, and the first terminal of the second energy storage element is coupled to the ground terminal.

Abstract: A neural network (NN) performs macro placement on a chip. A mask is updated to mark invalid regions occupied by already-placed macros on a chip canvas. A policy network of the NN generates summary statistics of a two-dimensional (2D) continuous probability distribution over a continuous action space for a given state of the chip canvas. The NN selects an action based on the continuous probability distribution. The selected action corresponds to a coordinate in an unmasked region. The NN generates a trajectory including (state, action) pairs. The final state in the trajectory corresponds to a completed placement of macros.

Abstract: Examples pertaining to cell discontinuous transmission (DTX) and user equipment (UE) discontinuous reception (DRX) are described. A UE receives a configuration of a cell DTX from a network node with a cell DTX functionality. The configuration carries information regarding at least one of a periodicity, a start slot or a start offset and an on duration. Then, the UE skips a monitoring activity during one or more non-active periods of the cell DTX of the network node.
