Abstract: In a heterogeneous wireless network that includes a macro base station and one or more micro base stations, a wireless device to wirelessly transmit, in a first time slot at a first position in a first transmission subframe, data over a first physical communication channel. An ACK/NACK control message is received over a backhaul network connection a first time period after the first time slot. A response message is transmitted to the wireless device such that when the control message is received prior to the second time slot, then the response message uses data reception information from the control message and when the control message is not received prior to the second time slot, then the response message indicates that the data was successfully received.

Abstract: The present document provides a method for avoiding downlink data collision, an Access Point (AP) and a Station (STA). The method for avoiding downlink data collision includes: an AP receiving a radio frame for inquiring whether the AP has a Bufferable Unit (BU) of an STA transmitted by the STA; and after determining that there is a BU of the STA and the BU is larger than a predetermined threshold, the AP exchanging radio frames with the STA to reserve a channel, and transmitting the BU to the STA after succeeding in reserving the channel. The method can guarantee the fairness among various STAs and the reasonable utilization of channel resources, thus avoiding the collision; furthermore, the channel reservation frame transmitted by the AP can reserve a longer period of time, i.e. a plurality of BUs can be transmitted to the STA at a time, thus saving the link overhead.

Abstract: In a wireless network, full duplex communication is established using a half-duplex mechanism. During a full duplex communication opportunity, a first quantum of data is transmitted from a first station to a second station and a second quantum of data is received by the first station from the second station. The full duplex transmission opportunity is implicitly or explicitly established and ended using a transmission mechanism understood by half duplex wireless stations.

Abstract: Provided are a radio frame sending method and apparatus. In the method, when entering an awake state from a doze state, a station selects a pre-defined access category or an access category which is pre-negotiated with a centre station to contend for a wireless channel. Afterwards, the station sends a radio frame to the centre station via the wireless channel obtained through the contention, and then notifies the centre station to send buffered data to the station. The method and apparatus can be applied to flexibly and dynamically regulate an access category used for contending for a wireless channel when a station sends a radio frame which is used for notifying a centre station to send buffered data to the station.

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.
