Abstract: Method, device and computer program product for wireless communication are provided. A method includes: receiving, by a wireless communication terminal, a first release message; and releasing, by the wireless communication terminal, at least one small data transmission, SDT, configuration stored in the wireless communication terminal according to a cell where the first release message is received or according to information of SDT configuration carried by the first release message.

Abstract: A battery door for a hearing device includes: a body having a bottom part and a sidewall, the bottom part having a first bottom surface and the sidewall having a first wall surface, the first wall surface comprising contact points for supporting a battery with a battery radius, wherein the first bottom surface and the first wall surface at least partly defines a battery compartment for housing the battery with the battery axis, wherein the contact points of the first wall surface arranged at a battery distance from the battery axis, and wherein a center axis perpendicularly crosses the pivoting axis and crosses the battery axis.

Abstract: It is provided a method, device and system for transmitting an ACK response in bidirectional data transmission. When receiving windows on both sides of a transmission are simultaneously full, no new information frames can be transmitted to the other side before the ACK timer times out. This situation is called an ACK interlock delay. In the present disclosure, a communication device actively transmits a control frame carrying an ACK response to an opposite communication terminal when it detects that the local receiving window and the receiving window of the opposite communication terminal are both full, thus avoiding ACK interlock delays, avoiding wasting time, and improving the rate of transmission and link establishment.

Abstract: A method for sending an ACK from the receiver to the sender is disclosed. The receiver starts an ACK timer with the ACK timeout value being smaller than the RTX timeout value. The ACK timer is stopped or cancelled when an ACK is sent from the receiver to the sender. When the number of the delayed ACK for I-frames is close to the receive widow size of the receiver or the ACK timer is timeout, the receiver sends an ACK to the sender actively. When the receiver receives a Poll frame from the sender due to RTX retransmission timeout, the receiver sends an ACK to the sender passively. The receiver adjusts the ACK timeout value used next time based on the following: timeout value of a current ACK timer, RTX timeout value of the sender, the receive widow size of the receiver and the number of I-frames for which ACKs have not been sent, in order to reduce the S-frames and stops of data transmission, thus improving the data transmission speed and the bandwidth utilization.

Abstract: This invention relates to a method used to switch input/output audio data streams seamlessly and related digital devices, wherein the digital device comprises a local physical sound card, a short-distance wireless communication module and an audio switching management module. When a wireless audio transmission channel is connected, the audio switching management module automatically passes the output audio data stream by an audio application module to a wireless audio device through the wireless audio transmission channel and passes the input audio data stream to the audio application module through the wireless audio transmission channel. When the wireless audio transmission channel is disconnected the audio switching management module automatically passes the output audio data flow to a wired audio device through the local physical sound card and passes the input audio data flow from the wired audio device to the audio application module through the local physical sound card.
