IPC: H04W74/08

Abstract: A method for processing a network allocation vector (NAV) includes: terminating the receiving of a first radio frame when it is determined that a target receiving station of the first radio frame being received is not a first station; and updating an NAV of the first station or maintaining the NAV of the first station unchanged according to a remaining duration of the first radio frame and a first transmission opportunity duration carried in the first radio frame, where the remaining duration of the first radio frame is the transmission time used for transmitting the remaining part of the first radio frame after the receiving of the first radio frame is terminated. The technical solution solves the problem in the related art of collisions with hidden stations caused by an inaccurate NAV update in the existing art, thereby ensuring the accuracy of an NAV update and the fairness of transmission and channel contention, and reducing collisions among hidden stations.

Abstract: Provided are a method, apparatus and system for mapping user plane data and a storage medium. The method includes that: a user plane higher-layer entity of a first network element receives a data packet sent by a second network element and carrying a specified identifier; and the user plane higher-layer entity maps the data packet to at least one of: a user plane lower-layer entity of the first network element, a radio bearer (RB), and a logical channel (LCH) according to the specified identifier. With the solution described above, the problem, in the related art, of lacking data packet mapping between the user plane higher-layer entity and the user plane lower-layer entity in the 5G system architecture is solved, and data packet mapping to the lower-layer entity and/or the RB, and/or the LCH in the 5G system is implemented by the user plane higher layer.

Abstract: A method and device for transmission instruction, transmission triggering and transmission implementation for multi-station. A first station sends a radio frame carrying instruction information on a competed channel with a bandwidth being a first bandwidth to an access point, and the instruction information being used for instructing the access point to trigger the first station, or, trigger the first station and one or more other stations to perform uplink transmission; the problem in the related art that, if some station obtains a certain channel resources in a contention manner and the station itself only occupies a part of the channel resources for transmission, since all the bandwidth resources obtained from the contention is already claimed by the station for occupation, and other stations are unable to compete for occupation, thereby the waste of frequency resources is caused, is solved, and further, the waste of the air interface resources during large bandwidth transmission is effectively avoided.

Abstract: Provided are a data sending feedback method and apparatus, and a data sending method and apparatus. According to data sending feedback method, when reception of a radio frame fails, a receiving station detects whether transmission of the radio frame over a specified sub-channel in a working channel ends within predetermined time; after the receiving station detects that the transmission of the radio frame over the specified sub-channel in the working channel ends within the predetermined time, the receiving station sends a feedback frame to a sending station of the radio frame. The above-mentioned technical solution solves the technical problem in the related art that a receiving station does not send a feedback frame upon unsuccessful reception of a radio frame and thus a sending station cannot learn a receiving condition of the radio frame in time. In this way, the sending station is enabled to acquire the receiving condition of the radio frame in time and providing a strong support for subsequent data sending or retransmission.
