Abstract

A method for operating a communications device in a wireless network involves managing application layer data as Packet Data Units (PDUs). The method includes transmitting PDUs via a physical layer while restricting transmission to the specific PDUs of a set. If a data segment fails to transmit successfully, the method terminates transmission of the remaining PDUs in the set, conserving resources and improving efficiency. Alternatively, the method provides feedback from the physical layer to higher layers, such as the PDCP layer, to terminate PDU transmission upon detecting a failure. This approach enhances reliability, reduces latency, and optimizes energy usage by preventing unnecessary retransmissions of failed PDUs or their sets. The method emphasizes resource efficiency and high-performance communication by leveraging cross-layer feedback and adaptive control.

Dependent claims

A method of communicating data by a communications device via a wireless communications network, the method comprising

receiving application layer data for transmission at a protocol stack formed by the communications device for transmitting the data, the data being either received from an application layer forming part of the protocol stack as a set of Packet Data Units, PDUs, or a layer of the protocol stack being configured to form the application layer data into a set of PDUs, each PDU of the set including an indication that the PDU belongs to the set,
transmitting each of the PDUs of the set using a physical layer of the protocol stack as one or more data segments by controlling a transceiver of the communications device, wherein the transmitting the PDUs of the set using the physical layer of the protocol stack comprises
restricting the physical layer transmission to limit the transmitting of the one or more data segments to correspond to communicating each of the PDUs of the set, and
determining that one of the data segments has not been communicated successfully, and
in response to determining that one of the data segments has not been transmitted successfully, terminating the transmitting of the set of PDUs, which is to communicate the application layer PDU.
