Abstract

A method for operating an access point (100) providing access to a wireless network for a plurality of wireless devices (200), wherein the wireless network comprises at least one transmission channel(40) with a sequence of transmission slots. The method comprises the steps of assigning a first transmission slot (46-48) of the sequence of transmission slots to a first wireless device of the plurality of wireless devices for a scheduled transmission with a priority access to the first transmission slot for the first wireless device, detecting during the first transmission slot (46-48) that thefirst wireless device is currently not transmitting data in the assigned first transmission slot, and transmitting an indication to at least a subset of the plurality of wireless devices (200) indicating that at least a time range in the first transmission slot until an end of the first transmission slot is available to the plurality of wireless devices for a data transmission using a random access procedure.

Description

technical field [0001] The present application relates to a method for operating an access point providing access to a wireless network for a plurality of wireless devices and to corresponding access points. Furthermore, a method for operating a first wireless device of a plurality of wireless devices, which accesses a transmission channel of a wireless network, is provided. Additionally, a corresponding access point and first wireless device and a system including the access point and first wireless device are provided. In addition, a computer program including program code and a carrier including the computer program are provided. Background technique [0002] IEEE 802.11, also known as WLAN or Wi-Fi, is a wireless technology operating in the ISM (Industrial, Scientific, Medical) frequency band. The most common mode of operation is contention based CSMA / CA (Carrier Sense Multiple Access / Collision Avoidance). Another known mode of operation is Point Coordination Function...
