Abstract: This document discloses a solution for device-to-device communications. According to an aspect, a method comprises in a first terminal device: establishing an association with an access node; establishing a direct wireless link with a second, non-access-node, terminal device; causing transmission of a message to the access node, the message comprising a buffer status report and at least one information element indicating the direct wireless link; receiving, in response to the message, a trigger frame indicating a resource unit allocated to the direct wireless link; in response to the trigger frame, causing transmission of a data packet to the second terminal device over the direct wireless link in the allocated resource unit.

Abstract: Example embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of dual-channel backhaul in mesh network. The method comprises: generating, at a first device, a first transmit queue comprising a plurality of data packets to be transmitted to a second device on a first backhaul link; in accordance with a determination that a distribution strategy is met, distributing at least one data packet from the plurality of data packets; generating a second transmit queue comprising the at least one data packet, the second transmit queue to be transmitted to the second device on a second backhaul link different from the first backhaul link; and transmitting, to the second device, the plurality of data packets except for the at least one data packet on the first backhaul link and the at least one data packet on the second backhaul link. By such a dual-channel backhaul architecture, the channel resources on the two channels can be fully utilized for backhaul.

Abstract: A first device in a communication network receives from at least one second device in the communication network, a first request for acquiring a token, the token being permission for communicating with a third device. Based on the first request, a device from the at least one second device and the first device as a communication device is selected for providing a communication service to the third device in the communication network; and the token is transmitted to the communication device. The communication device receives the token for communicating with the third device. Other devices receive key information associated with communication of the third device from the first device, and monitor data associated with the communication of the third device.
