Embodiments of a method and apparatus for wireless communications are disclosed. In an embodiment, a wireless device includes a wireless transceiver configured to communicate within a transmit opportunity (TXOP), where the wireless transceiver is further configured to receive a frame indicating a preemption allowance for low latency indication frame transmission from a second wireless device, and a controller configured to control the wireless transceiver to pause or resume data transmission within the TXOP in response to the frame indicating the preemption allowance for low latency indication frame transmission from the second wireless device.

There is provided a communication apparatus and a terminal apparatus that can improve low latency operation performance. The communication apparatus includes a control unit that configures a configuration value related to a DRX operation in a terminal apparatus depending on a state of the terminal apparatus that can perform wireless communication by both a first communication scheme and a second communication scheme; and a transmission unit that transmits the configuration value configured by the control unit to a base station apparatus or the terminal apparatus. In a case that the terminal apparatus is in a first state, the control unit configures the configuration value to a first value for the first communication scheme and the second communication scheme in such a manner that the first communication scheme and the second communication scheme come into an active state at temporally different timings, with regard to the DRX operation.
