  • Publication number: 20200404560
    Abstract: When a quantity of radio resources available for a terminal device is less than a quantity of required radio resources, the terminal device sends a request to another terminal device, to request the another terminal device to release at least one radio resource currently used by the another terminal device or reselect a radio resource. The another terminal device that receives the request may autonomously release or request a network to release the at least one radio resource currently used by the another terminal device, or autonomously reselect or request a network to reselect the radio resource, and send a response to the terminal that sends the request. Nonconsecutive fragmented radio resources may be integrated into consecutive and relatively large radio resources, so that radio resource fragments are reduced, and the terminal device can send control information and data in a timely manner, thereby improving radio resource utilization.

  • Publication number: 20200236597
    Abstract: In various embodiments, an access point sends a first frame. The first frame carries a TXOP handover enforcement THE indication field which is a first value or a second value. The first value instructs a station that has accessed a channel to hand over a held TXOP to the access point, and the second value instructs the station that has accessed the channel to hand over the held TXOP to the access point when a handover condition is satisfied. It can be learned that the STA hands over the held TXOP to the AP. Therefore, the AP may be a TXOP holder through the TXOP handover even if the AP fails to obtain the channel through contention, so that a probability of holding the TXOP by the AP is improved, a probability of scheduling a STA by the AP is improved, and system resource utilization is improved.

  • Publication number: 20190379508
    Abstract: Embodiments relate to the field of wireless communication technologies and provide a method for performing channel sounding, a network-side device, and a terminal. A first terminal sends a resource scheduling request to a network-side device when the first terminal starts a communication connection with a second terminal. The resource scheduling request carrying information about the second terminal requests the network-side device to allocate a transmission resource for channel sounding between the first terminal and the second terminal. The first terminal receives a sounding reference signal sent by the second terminal, and obtains information of a channel for communication between the first terminal and the second terminal. The method enables quick and effective channel sounding between terminals, thereby increasing communication efficiency between the terminals.
