US 2023/0413267 A1 · Semantic Communication and Programmable Protocol Stack: Media Access Control

Abstract

This disclosure relates to techniques for performing communication in a wireless communication system. The communication may be semantic communication and/or may use a programmable protocol stack. A protocol stack at a transmitter and/or receiver may include customization from an application platform, e.g., which may replace one or more layers relative to a non-customized protocol stack. A transmitter may transmit data, via the customized protocol stack, using a best effort data channel, e.g., with transmission characteristics that are relatively lossy in comparison to a data channel used by the non-customized protocol stack. A receiver may receive the data and may determine whether reception is successful, e.g., from a semantic point of view. A media access control layer may interact with both the customized and non-customized stacks. The proposed system may support higher data rates, less retransmissions, and/or better quality of user experience.

Dependent claims

A method, comprising:

at a media access control (MAC) layer of a base station of a cellular network:
establishing communication with a first user equipment (UE);
receiving, from a higher layer of a first protocol stack operating according to a 3 GPP wireless standard, first data for the first UE;
receiving, from a layer of a second protocol stack, different from the first protocol stack, associated with a first application platform, an indication that the second protocol stack has second data for the first UE;
exchanging one or more coordination message with the layer of the second protocol stack to determine a standardized resource sharing for transmission of the first data and the second data to the UE;
and
providing, to a physical layer of the base station, the first data for transmission to the first UE according to the standardized resource sharing.
