Abstract: On a first channel, an access point (10) of the wireless communication system maintains a first wireless link to a first wireless station (11). On a second channel, the access point (10) maintains a second wireless link to a second wireless station (11). Further, the access point receives a measurement report from the first wireless station (11). The measurement report represents a level of interference from the second channel to the first channel. Based on the measurement report, the access point (10) controls multi-link operation on the first wireless link and the second wireless link.

Abstract: 36626WO FB/MS/br - 35 - Abstract Channel access coordination for TXOP sharing An access point of a wireless communication system operates on a primary bandwidth part 5 (Ch2, Ch3) of a medium. This operation on the primary bandwidth part (Ch2, Ch3) is based on carrier sensing to gain access to the primary bandwidth part of the medium. Further, the access point scans a secondary bandwidth part (Ch1, Ch2) of the medium to detect control messages transmitted on the secondary bandwidth part (Ch1, Ch2), without performing carrier sensing to gain access to the secondary bandwidth part (Ch1, Ch2) of the medium. Further, the AP 10 detects a control message indicating that another AP reserved a transmission opportunity, TXOP, on the secondary bandwidth part (Ch1, Ch2) of the medium. In response to the control message, the AP cooperates with the other AP by sharing the TXOP for performing one or more transmissions of data. 15 (Fig. 6)

Abstract: 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.

Abstract: An access point (10) of a wireless communication system configures a carrier for communication with one or more wireless devices (11) associated with the access point (10). Further, the access point (10) 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 (10) cooperates with one or more other access points (10) of the wireless communication system by sharing the TXOP based on spatial multiplexing of wireless transmissions on the carrier.

Abstract: In a wireless communication system, an access point (10) contends with at least one further access point (10) for a set of transmission resources. In response to winning contention for the set of transmission resources, the access point (10) shares at least a subset of the transmission resources with the at least one further access point (10). In addition, the access point (10) exchanges information with the at least one further access point (10). Based on the exchanged information, the access point (10) coordinates wireless transmissions on the shared subset of transmission resources.

Abstract: An approach of transmission comprises a method of enabling Hybrid Automatic Request, HARQ, in an IEEE 802.11 communication. The method comprises 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 comprises 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.

Abstract: A transceiver device comprises a controller arranged to identify a first set of control information within the data packet, and to re-map the data packet such that the first set of control information is mapped on bits known to be more robust. The transceiver device further comprises a transmitter arranged to transmit the re-mapped data packet. The first set of control information holds information which enables for identification to combine soft bits from repeated transmissions at a receiver of the packet. The bits known to be more robust have more distinct value distribution in signal space of a used modulation and coding scheme than other bits. The transceiver device is arranged to transmit a data packet. A corresponding method, computer program, access point and station are also disclosed.

Abstract: A technique for transmitting data from a passive radio device (100) is described. As to a method aspect of the technique, an antenna (102) of the passive radio device (100) is exposed to an incident radio signal (502). A frequency domain representation of the incident radio signal (502) comprised at least one muted gap between active subcarriers within a bandwidth of the incident radio signal (502). The incident radio signal (502) is backscattered from the antenna by modulating an impedance of the antenna according to the data using at least two different modulation frequencies that differ by less than the bandwidth.
