Abstract: A communications device (304) and a method for providing an improved channel access procedure for transmission of data. The communications device and an Access Point (AP) (302) are operating in a wireless communications network (300). The communications device performs a channel sensing procedure using a second slot counter Bn, which second slot counter is equal to a random backoff value or a first slot counter Sn. When trigger frame is received from the AP during the channel sensing procedure, which trigger frame triggers access to a channel, the communications device sets the first slot counter equal to the second slot counter and transmits the data to the AP on the channel. The communications device sets the first slot counter equal to a preset value and transmits the data to the AP in the absence of a received trigger frame and when the channel sensing procedure is completed.

Abstract: There is provided access to a communications channel in a wireless communications network. Stations (STAs) associated with an access point (AP) are grouped in at least two groups of STAs, each group being associated with a minimum transmission power level needed by the AP to communicate with the STAs in that group. A first time interval is allocated for a first group of STAs associated with highest minimum transmission power to access the communications channel concurrently with a third time interval being allocated by another AP for a third group of STAs associated with lowest minimum transmission power level needed by said another AP to communicate with the third group of STAs to access the communications channel.

Abstract: A transmitting node and a method performed by a transmitting node for performing data transmissions to at least one receiving node on a radio channel in a wireless communications network. First, the transmitting node sets at least two contention window sizes. The at least two contention window sizes are separately determined based on information associated with the least one receiving node. Then, the transmitting node defers a first transmission of data to the at least one receiving node for a first period and also defers at least one second transmission of data to the at least one receiving node. Further, the transmitting node performs a first or at least one second transmission of data to the at least one receiving node when an outcome of a corresponding first and at least second periods of observation of the radio channel, respectively, is that the radio channel is idle.

Abstract: This invention defines a medium access protocol for the support of mesh networking in wireless communications. It defines a phase for intra-cell and a phase for inter-cell traffic. During the inter-cell traffic a beacon phase is used for the reservation of transmissions. In this phase also information about the mesh topology is included and parallel transmission are supported. Even though this medium access protocol is intended to be proposed in standardization of IEEE 802.11 mesh networks (802.11) it could be used in any wireless mesh network.
