An access point of a wireless communication system configures a carrier for communication with one or more wireless devices associated with the access point. Based on a backoff counter maintained by the access point, the access point contends for access to the carrier to transmit data. In response to another access point winning contention for access to the carrier, the access point cooperates at least with the access point winning the contention by sharing a transmission opportunity reserved on the carriers by the access point winning the contention and transmitting at least a part of the data in the shared transmission opportunity. During the shared transmission opportunity the access point pauses the backoff counter.

Backoff counter handling for TXOP sharing

An access point () of a wireless communication system configures a carrier for communication with one or more wireless devices () associated with the access point (). Further, the access point () contends for access to the carrier and, in response to winning contention for access to the carrier, reserves a transmission opportunity, TXOP, on the carrier. Further, the access point () cooperates with one or more other access points () of the wireless communication system by sharing the TXOP based on spatial multiplexing of wireless transmissions on the carrier.

Sharing of TXOP based on spatial multiplexing

An approach for transmission provides a method of enabling Hybrid Automatic Request, HARQ, in an IEEE 802.11 communication. The method includes transmitting, in an element in a Block Acknowledgement, BA, setup of a Medium Access Control, MAC, message, which element indicates a request to use HARQ, receiving a response to said request, and starting to apply HARQ. The approach includes a network entity of a wireless network using IEEE 802.11. The network entity includes a transmitter arranged to transmit, in an element in a Block Acknowledgement, BA, setup of a Medium Access Control, MAC, message, which element indicates a request to use HARQ, a receiver arranged to receive a response to said request, and a communication handler arranged to start to apply HARQ.

A technique for performing a multi-layer transmission of data on a radio frequency is described. The multi-layer transmission comprising multiple layers each having a different robustness on the radio frequency. As to a method aspect of the technique, a contention procedure is performed with respect to each of a plurality of access classes, ACs, for accessing the radio frequency. The multi-layer transmission is performed upon success of the contention procedure of at least one of the ACs. In a transmission opportunity defined by the successful contention procedure, data associated with the successful AC is transmitted on a main layer of the multi-layer transmission simultaneously with data associated with at least one further AC on at least one further layer, which is less robust than the main layer of the multi-layer transmission.
