Abstract:
Disclosed is a method and device for configuring sidelink resources. The method includes: a network side indicates time domain resources of a sidelink resource pool used for sidelink communication, where the sidelink resource pool includes at least one slot in time domain, and a slot includes at least one time domain symbol, the time domain resources of the sidelink resource pool are dedicated resources of the sidelink communication, or resources shared by the sidelink communication and a cellular link. Further disclosed are a system for configuring resources, and a storage medium.
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:
A method of setup a protection mechanism for scheduled transmissions to multiple stations is introduced. Through transmitting a control frame addressing to multiple stations for immediate simultaneous responses, the transmitter would know the stations that are ready for receiving the scheduled data frames and schedule the packet for those stations. Combining the transmission of the control frame with the power saving mechanism would allow triggering a group of power saving stations to wake up at same for receiving the control frame and scheduled user data frames. A new mechanism of simultaneous group responses to the control frame with orthogonal identifier information for individual station is provided to uniquely identify the responding stations.
Abstract:
Access to a wireless medium is controlled based on contention arbitration. A certain number of wireless devices are allowed by an access point to contend for a transmission opportunity. A trigger frame is used to communicate access opportunities to multiple devices. A beacon transmission may additionally be used for communication of access opportunities.
Abstract:
Provided are a method and system for a wireless STA to access a channel. The method includes that the wireless STA acquires a transmission ending moment of a wireless frame when selecting to refuse or drop the wireless frame and not updating a locally stored Network Allocation Vector (NAV); and the wireless STA accesses the channel when the transmission of the wireless frame is ended and a preset condition is met. According to the disclosure, a collision problem may happen to the wireless STA, and the wireless STA can access the channel only when the preset condition is determined to be met after the transmission of the wireless frame is ended, so that the problem of transmission collision with a hidden STA during the wireless frame transmission of the wireless STA is solved.

Abstract:
A transmitting wireless device dynamically and periodically transmits beacon frames including either full set of information or a partial information about the BSS. The wireless device schedules the target beacon transmission time and target dynamic beacon transmission time to have different starting time and different interval for each BSS. A Nack based mechanism for detecting and report missing dynamic beacon frames is used to provide the wireless access point with a feedback information of dynamic beacon transmission for improving the transmission efficiency and reliability.

Abstract:
Provided are a symbol attribute determination method, a node and a storage medium. The symbol attribute determination method includes determining the attribute of a symbol by using a first mode. The attribute includes the attribute of being unavailable or the attribute of being available. The first mode is a default mode or a configured mode.
Abstract:
Provided are a timing information configuration method, apparatus and system and a storage medium. The timing information configuration method includes that a first node predefines or configures timing information of a second node. The timing information includes at least one of: a timing mode, a downlink transmission timing alignment mode, a timing advance (TA) configuration mode, a TA value, an offset of a TA value, a number of orthogonal frequency division multiplexing (OFDM) symbols that an uplink transmission timing is advanced or delayed relative to a downlink transmission timing for alignment, or a number of OFDM symbols that an uplink reception timing is advanced or delayed relative to a downlink reception timing for alignment. The timing information configuration method includes that a second node determines timing information of the second node in a manner of predefinition or in a manner of being configured.
