  • Patent number: 11611973
    Abstract: Examples pertaining to improvement on user equipment (UE) uplink latency in wireless communications are described. When an apparatus is in a special mode, a processor of the apparatus transmits to a network a request for permission to perform an uplink (UL) transmission for a plurality of times. The processor then receives from the network a grant. In response to receiving the grant, the processor performs the UL transmission to the network. In transmitting the request for the plurality of times, the processor transmits the request for the plurality of times at a frequency higher than a frequency at which the request to perform UL transmissions is transmitted to the network when the apparatus is in a normal operational mode.

  • Publication number: 20220408365
    Abstract: A power optimization method for uplink data transmission is provided. The power optimization method is applied to user equipment (UE). The power optimization method includes the following steps. The UE determines the current application scenario of the UE. The UE determines the data transmission window corresponding to the current application scenario. Data transmission windows corresponding to different application scenarios of the UE have at least one of different period to transmit data and different period to enter suspension. The UE may transmit data based on the determined data transmission window.

  • Publication number: 20210297898
    Abstract: A wireless communication method for reducing the receival of unwanted data is provided. The wireless communication method for a TCP session includes the steps of determining whether a TCP session associated with a first subscriber identity module (SIM) of the UE is not required; and in response to determining that the TCP session is not required, the processor terminates the TCP session.
