The present disclosure provides a method and a device in wireless communication. In one embodiment, the UE first receives a first signaling, then receives a second signaling, and finally receives a first radio signal on target time-frequency resources; wherein the target time-frequency resources comprise time-frequency resources among second time-frequency resources other than first time-frequency resources, and the second signaling is used for determining whether the target time-frequency resources comprise the first time-frequency resources and the second time-frequency resources. The present disclosure makes effective use of the remaining time-frequency resources that transmit control information in a time interval less than 1 millisecond, thus improving resource utilization.

Disclosed are a wireless communication system, a network device, and a terminal device. The network device dynamically configures a structure and a frame length of a current communication frame, and sends frame structure configuration information of the current communication frame in the current communication frame. The terminal device obtains the structure and the frame length of the current communication frame according to the frame structure configuration information of the current communication frame. A frame structure is dynamically configured, so as to consider different service characteristics and requirements for diverse data services in the future, design a frame structure with flexible dynamical resource configuration and satisfying both link adaptation and service requirement adaptation, and satisfy requirements of devices with different processing capabilities for processing time. The frame length is dynamically configured, so as to reduce the control overhead and scheduling overhead and decrease the implementation complexity.

Wireless communication system and device

Disclosed is a method for adjusting a demodulation pilot frequency in a wireless communication system, comprising: acquiring at least one among a wireless channel characteristic parameter, device capability information, and system requirement information; configuring in real-time, on the basis of the wireless channel characteristic parameter/device capability information/system requirement information acquired, different demodulation pilot frequency patterns for different transmission during a transmission process; notifying a receiving-end device the demodulation pilot frequency patterns employed. The present invention also provides a corresponding system for adjusting the demodulation pilot frequency. The present invention is not only capable of adjusting the configuration of the pilot frequency on the basis of device performance and system requirement, but also capable of adjusting the configuration of the pilot frequency on the basis of changes in wireless transmission environment. This allows the configuration of the pilot frequency to adapt to changes in communication link, thus facilitating improved transmission reliability, and allowing increased average capacity for the system.
