Abstract: A method of operating a communications device in a wireless communications network is provided, the method comprising transmitting to an infrastructure equipment of the wireless communications network a time source indication, the time source indication indicating to the infrastructure equipment that the communications device is a source of timing information. The timing information may be in accordance with a non-3GPP protocol, may be generated outside of the wireless communications network, and/or may be used by entities (including logical protocol entities, applications and the like) which are outside of the scope of 3GPP specifications. An example of such timing information is time information which is compliant with the IEEE 802.1AS specification. According to the present methods, a wireless communications network can support time sensitive networking based on timing information which may have its origin and/or destination(s) outside the scope of the wireless communications network.

Abstract: A method of processing data frames for transmission on a wireless access interface of a wireless communications system, the method comprising receiving a first data frame comprising a first protocol header, the first protocol header associated with a medium access control (MAC) frame format for data transmission within a local area network (LAN), applying header compression in accordance with a header compression context to the first data frame by compressing one or more protocol header fields of the first protocol header to form a first compressed data frame for transmission on the wireless access interface, receiving a second data frame comprising a second protocol header associated with the MAC frame format, and determining that none of the fields of the second protocol header are to be compressed in accordance with the header compression context before the second data frame is transmitted on the wireless access interface.

Abstract: A method for determining a route in an Integrated Access Backhaul “IAB” mesh zone. The method comprises transmitting, to each IAB node of a plurality of IAB nodes, one or more discovery parameters for each IAB node; determining one or more route selection parameters for each IAB node to select a route; a first IAB node of the plurality of IAB nodes determining, based on the one or more discovery parameters, that a second IAB node of the plurality of IAB nodes is discoverable; and upon receiving a packet, selecting a route from the first IAB node based on the one or more route selection parameters and on the first IAB node determining that the second IAB node is discoverable.

Abstract: A method of operating a communications device in a wireless communications network, the wireless communications network comprising infrastructure equipment providing a wireless access interface, the method comprising: receiving a downlink control information (DCI) message, the DCI message comprising a time domain indication of a start time and a duration of communications resources of the wireless access interface, and determining the start time and the duration of the allocated communications resources based on the time domain indication. The time domain indication comprising an indication a combined start and length indicator value (SLIV) calculated based on a symbol period number and a duration, and a slot offset, when the allocated communications resources are within a single time slot, and determining a start time by determining the symbol period number indicated by the SLIV value calculated using either a first rule or a second rule and the slot offset value.

Abstract: A method of operating a communications device to receive data from a wireless communications network is provided. The method comprises receiving a plurality of downlink transmissions in physical downlink shared channel resources of a wireless access interface provided by the wireless communications network. Each downlink transmission is a transmission of a data unit transmitted according to a different Hybrid Automatic Repeat Request, HARQ, type process. The method comprises determining that an uplink transmission of the HARQ-ACKs, which is scheduled in uplink resources of the wireless access interface, is cancelled and cannot be transmitted in the scheduled uplink resources and receiving a trigger from the wireless communications network to transmit the cancelled HARQ-ACKs in subsequently scheduled uplink resources by selecting one of a plurality of configured HARQ-ACK codebooks to transmit the cancelled HARQ ACKs, wherein the configured HARQ-ACK codebook is selected based on one or more conditions.
