摘要： A method of communicating between nodes on a plurality of channels within the unlicensed spectrum is disclosed where coordination of the acquiring of the different channels is provided so that a further channel is acquired prior to the occupancy time of the currently used channel expiring. The method involves determining at one node that a channel in the unlicensed band has been acquired for a predetermined occupancy time. Initiating a scan of at least one further channel within the unlicensed spectrum to determine if a further channel is available. Once a predetermined time has passed and within the predetermined occupancy time, acquiring the available channel by transmitting a signal on it.

摘要： A method of scheduling user equipment, a multiple antenna network node and computer program are disclosed. The method comprises: estimating at least one access network node channel within the unlicensed band between at least one access node operable to transmit in the unlicensed band, such as a WiFi Access Point, and the multiple antenna network node. Estimating a plurality of user equipment channels within the unlicensed band between a plurality of user equipment and the multiple antenna network node. Determining a degree of channel correlation of each of the plurality of user equipment channels and the at least one access node channel. Selecting at least one of the multiple user equipment to be scheduled, using the degree of channel correlation as a selection parameter, a lower degree of channel correlation increasing a user equipment's chance of being selected. In this manner the interference that LTE transmissions from and to scheduled UEs create on the at least one access node is reduced.

摘要： According to an example aspect of the present invention, there is provided a method, including receiving, by a wireless device of a first wireless network, a control request frame from a second access node of a second wireless network, the control request frame including at least a number of nulls for the wireless device. The wireless device selects a subset of antenna elements, wherein the number of antenna elements is in accordance with the number of nulls for the wireless device, and the antenna elements are selected based on reception powers of antenna elements of at least a frame from a first access node of the first wireless network and/or the second access node of the second wireless network. The wireless device transmits a control response frame with the selected antenna elements, and a data frame to the first access node with the selected antenna elements.

摘要： Example embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of channel coordination in the unlicensed spectrum. The method comprises receiving, at a first device and from a plurality of second devices, information about carrier sensing to be performed by the plurality of the second devices; determining a transmission pattern for a target second device of the plurality of the devices based on the information about the carrier sensing and information about time sensitive traffic of the plurality of the second devices, the transmission pattern including at least a sensing period for transmission of time sensitive traffic of the target second device and a muting period of the target second device; and transmitting a first message indicative of the transmission pattern to the target second device. In this way, the interoperability of the TSN network device and the normal network device can be efficiently improved in an industrial automation scenario. By controlling the access/transmission of the TSC traffic in the TSC dedicated transmission period, the TSC traffic of the target network device can be protected and the latency requirements can be satisfied.
