Techniques for enhancing performance in Industrial Internet-of-Things (IIoT) scenarios, including techniques for time-sensitive networking (TSN) and 5G wireless network integration. An example method, performed by a wireless device, comprises receiving system information (SI) from a radio base station (RBS) of a radio access network (RAN), the SI being indicative of support for TSN through the RBS, and establishing at least one TSN stream with an external data network, through the RBS. The example method further includes receiving a first timing signal from the wireless communications network, via the RBS, receiving a second timing signal from the external TSN data network to which the wireless device is connected, comparing the first timing signal to the second timing signal to determine an offset, and transmitting the offset to the wireless communications network.

Industrial automation with 5G and beyond

A method performed by a transmitting device, in a 3GPP wireless communicationsystem (), for handling generalized Precise Timing Protocol (gPTP) signaling, from a Time Sensitive Network (TSN) is provided. The transmitting device receives () a gPTP frame from the TSN network. The gPTP frame comprises time information, an indication of a time domain related to the time information and/or a Medium Access Control (MAC) address of a second end station connected to a receiving device. Basedon the indication of the time domain and/or the MAC address, the transmitting device determines () the receiving device which the gPTP frame relates to. The transmitting device transmits (), to the determined receiving device, the gPTP frame in a PDU session related to the determined receiving device.

Devices and methods for handling precise timing protocol frames

Methods and apparatus are provided. In an example aspect, a method in a network node is provided, the method comprising monitoring unlicensed spectrum access attempts for transmissions to and/or from at least one User Equipment, UE, in a first group of UEs configured to use unlicensed spectrum to send uplink transmissions and/or receive downlink transmissions and, in response to the monitoring, causing the UEs in the first group to use licensed spectrum to send uplink transmissions and/or receive downlink transmissions.

Using unlicensed and licensed spectrum

A method is disclosed of transmitting a communication. The method comprises performing a Clear Channel Assessment, CCA, procedure on a first channel in unlicensed spectrum, and, if the CCA procedure indicates that the first channel is occupied for at least a predetermined period, transmitting the communication on a second channel in licensed spectrum.

Transmitting a communication on a first channel or a second channel

A Virtual Endpoint and a method therein for enabling end-to-end connectivity between a wireless communication network and a wired communication network are disclosed. A Virtual Endpoint is implemented in the wireless communication network and certain user and control plane features used in the wired communication network are implemented in the VEP. The VEP maps data traffic between a device in the wireless communication network and a device in the wired communication network based on Quality-of-Service (QoS) and performs required actions defined by the features used in the wired communication network.

Methods for interworking between wireless and wired communication networks

Methods and apparatus are provided. In an example aspect, a method of transmitting data is provided. The method comprises determining if a first channel on a first cell is occupied and, if the first channel on the first cell is occupied for at least a predetermined period, transmitting the data on a second channel on a second cell.

Transmitting data when a first channel on a first cell is occupied

A device () is arranged on a source side of a wireless link () and receives data traffic from one or more source devices (). The device () forwards the data traffic via the wireless link () and via a further device (), which is arranged on a destination side of the wireless link (), towards one or more destination devices (). The device () receives redundancy information from the further device (). The redundancy information indicates redundant payload which is common to multiple data frames in the data traffic forwarded by the device (). Based on the redundancy information, the device () removes the indicated redundant payload from at least a part of the data traffic to be forwarded by the device ().

Redundancy control for data traffic through a wireless link

Embodiments of the disclosure provide methods, apparatus and machine-readable media relating to transport of data flows over cellular network. One method in a core network node comprises: obtaining configuration information for a data stream in an external data network, the configuration information indicating respective values for one or more fields within a header of data packets associated with the data stream which are to remain static; initiating transmission of the configuration information to a wireless device which is to receive the data stream; receiving a data packet associated with the data stream from the external data network; removing the one or more fields from the data packet to generate a compressed data packet; and initiating transmission of the compressed data packet to the wireless device.

Transport of data flows over cellular networks

A technique for Time-Sensitive Networking, TSN, over a radio access network, RAN, is described. As to a handling method aspect of the technique, system information is received from a radio base station of the RAN. The system information is implicative or indicative of support for TSN through the radio base station. Depending on the received system information, at least one TSN stream of the TSN through the radio base station is established or initiated to establish.

The disclosure provides various methods for time-aware scheduling of time-sensitive network (TSN) streams in 5G networks. One method, performed in a core network associated with a radio access network (RAN), is for scheduling resources in the RAN according to a transmission schedule associated with an external network. The method comprises receiving (), from the external network, a transmission schedule associated with a time-sensitive data stream and sending (), to the RAN, a request to allocate radio resources for communication of the data stream between the RAN and a user equipment (UE). The request further comprises information related to the transmission schedule. The method also comprises receiving (), from the RAN, a response indicating whether radio resources can be allocated to meet the transmission schedule associated with the data stream.
