Communications device, infrastructure equipment and methods

A method of transmitting data by a communications device in a wireless communications network, the method comprising

• receiving a data from each of a plurality of logical channels, each of the logical channels having an assigned relative priority,
• receiving a first downlink control message allocating first uplink communications resources of a wireless access interface for transmitting a transport block which is to carry the data from one or more of the plurality of logical channels,
• determining, based on the received first downlink control message, a priority for filling an available capacity of the transport block with the data from one or more of the plurality of logical channels, and
• transmitting the transport block in the allocated first uplink communications resources.

A method of receiving data by an infrastructure equipment in a wireless communications network, the method comprising

• transmitting a first downlink control message comprising an indication of a first dynamic grant allocating first uplink communications resources for transmission of data by a communications device,
• transmitting a second downlink control message, the second downlink control message comprising an indication of a second dynamic grant allocating second uplink communications resources for transmission of data by the communications device, and
• receiving a transport block using the first uplink communications resources, wherein
• the second uplink communications resources comprise at least a portion of the first uplink communications resources, and
• the first uplink communications resources are associated with a higher priority than the second uplink communications resources.
