摘要： A Bluetooth-based data transmission method is provided. The method is applied on a first device and includes the following steps: establishing a communication connection with a second device; determining a sniff interval which comprises a sniff wake-up window; entering a sniff mode; and transmitting a first data packet to the second device in the sniff interval. The transmission duration of the first data packet is longer than or equal to two time slots. The step of transmitting the first data packet to the second device in the sniff interval includes the steps of starting to transmit the first data packet to the second device in an even time slot of the sniff interval or in an odd time slot of the sniff interval. With the data transmission method of the present application, synchronization between transmission of the first device and reception of the second device can be realized.

摘要： A method pertaining to leftover bits processing for proportional round-robin resource unit (RU) parsing in extreme high-throughput (EHT) systems involves processing a stream of bits to provide processed bits. The method also involves transmitting the processed bits to a station (STA) over a combination of multiple resource units (RUs) assigned to the STA. In processing the stream of bits, the method may involve parsing the stream of bits to the combination of multiple RUs. Moreover, in an event of leftover bits remaining from the parsing, the method may further involve distributing the leftover bits to one or more RUs but not all RUs of the combination of multiple RUs.

摘要： Various solutions for synchronization in non-terrestrial network (NTN) communications are proposed. An apparatus implemented in a user equipment (UE) obtains at least one of a downlink (DL) pre-compensated frequency value applied on a service link from a satellite of a non-terrestrial network (NTN) and a feeder link delay drift rate of a feeder link between a network node and the satellite. The apparatus further obtains a Doppler frequency shift value. Then, the apparatus performs a timing compensation through adjusting a sampling rate according to at least one of the DL pre-compensated frequency value, the feeder link delay drift rate, and the Doppler frequency shift value.

摘要： Solutions pertaining to adjusted public land mobile network (PLMN) search in mobile initiated connection only (MICO) mode in mobile communications are proposed. An apparatus implemented in a UE activates a MICO mode. The apparatus then postpones a periodic PLMN search in response to the UE being in the MICO mode, with the periodic PLMN search being controlled by a timer.

摘要： An acoustic echo cancellation (AEC) system includes a loudspeaker interface coupled to a loudspeaker, a microphone interface coupled to a microphone, and a processor executing a model. The model is arranged to predict and generate a spectral magnitude mask (SMM) through a neural network according to a first microphone signal output by the loudspeaker and a second microphone signal output by the microphone, wherein a noisy speech signal is a sum of a clean speech signal and a noise signal; the SMM is a ratio of a spectral magnitude of an estimated speech signal and a spectral magnitude of the noisy speech signal; a true mask is a ratio of a spectral magnitude of the clean speech signal and the spectral magnitude of the noisy speech signal; and a loss function of the model is a mean square error between the SMM and the true mask.

摘要： An acoustic echo cancellation (AEC) system includes an adaptive filter, a subtraction circuit, and a processor executing a model. The adaptive filter is arranged to generate an estimated echo signal according to a first microphone signal played by a loudspeaker. The subtraction circuit is arranged to subtract the estimated echo signal from a signal that is output from a microphone receiving both of a speech signal and an echo signal, to generate a second microphone signal, wherein the first microphone signal is not output from the microphone, and the echo signal is transmitted from the loudspeaker to the microphone. The model is arranged to perform short-time Fourier transform upon the first microphone signal and the second microphone signal, respectively, and generate an estimated speech signal through a neural network according to a first transformed microphone signal and a second transformed microphone signal.

摘要： Ternary content-addressable memory (TCAM) devices are described. The TCAMs described herein are designed to perform write operations—including data writes and mask writes—in a single clock cycle. For example, data input is written in a row of the TCAM during the first portion of a clock cycle, and a mask is written in another row of the TCAM during the second portion of the clock cycle, for example immediately after or after a programmable delay from the data write. In one implementation, a first bus is used both for data write and key search operations, and a second bus is used both for mask write and search masking operations. In another implementation, a first bus is used both for data write and key search operations, a second bus is used for mask write operations, and a third bus is used for search masking operations.

摘要： Solutions pertaining to spectrum sharing in coordination between a non-terrestrial network (NTN) and a terrestrial network (TN) are proposed. An apparatus implemented in a UE measures a signal strength of each of one or more TN cells and one or more NTN cells. The apparatus reports a result of the measuring to a TN. The apparatus also receives an indication from the TN configuring and activating a bandwidth part (BWP) that separates transmission by a base station of the TN from NTN downlink (DL) transmissions.

摘要： A first apparatus communicates with a second apparatus via a first link in a first frequency band and via a second link in a second frequency band different than the first frequency band by performing operations. For example, the first apparatus performs an independent enhanced distributed channel access (EDCA) on each of the first link and the second link. Then, the first apparatus obtains a transmit opportunity (TXOP). Next, the first apparatus synchronizes a starting time and/or an ending time of a transmission and a reception on the first link and the second link to avoid causing an in-device coexistence (IDC) interference due to the transmission and the reception occurring simultaneously. Alternatively, the first apparatus refrains from transmitting and receiving on the first link and the second link simultaneously to avoid causing the IDC interference.
