Abstract
A transportation vehicle, a network entity, apparatuses, methods, and computer programs for communicating messages with other transportation vehicles and for adapting a physical layer configuration. The method for a transportation vehicle and for communicating messages with other transportation vehicles in a mobile communication system includes communicating broadcast messages using a first physical layer configuration of the mobile communication system and communicating non-broadcast messages using a second physical layer configuration of the mobile communication system.
Claims23
A transportation vehicle apparatus for communicating messages with other transportation vehicles in a mobile communication system, the apparatus comprising:
- one or more interfaces configured to communicate in the mobile communication system;
- and
- a control module configured to control the one or more interfaces, wherein the control module controls the one or more interfaces to:
- in response to determining that a message is a broadcast message, communicate the broadcast message using a first physical layer configuration of the mobile communication system,
- in response to determining that a message is a non-broadcast message, adapt a configuration of the physical layer to a second configuration, wherein a first spectral efficiency of the first configuration is less than a second spectral efficiency of the second configuration, and wherein to adapt includes communicate, to the other transportation vehicles, information related to adapting the configuration of the physical layer by decreasing a subcarrier spacing, and in response to receiving a plurality of adaptation proposals from the other transportation vehicles, compare corresponding robustness of the received adaptation proposals to identify one of the received adaptation proposals having a highest robustness and adapt the second configuration of the physical layer to correspond to the one of the received adaptation proposals, and
- communicate the non-broadcast message to the other transportation vehicles using the second physical layer configuration of the mobile communication system.
A network entity apparatus for adapting a physical layer configuration for communicating non-broadcast messages among a plurality of transportation vehicles in a mobile communication system, the apparatus comprising:
- one or more interfaces to communicate in the mobile communication system;
- and
- a control module configured to control the one or more interfaces, wherein the control module controls the one or more interfaces to:
- communicate broadcast messages using a first physical layer configuration of the mobile communication system;
- and
- communicate non-broadcast messages using a second physical layer configuration of the mobile communication system.
A method for a transportation vehicle and for communicating messages with other transportation vehicles in a mobile communication system, the method comprising:
- in response to determining that a message is a broadcast message, communicating the broadcast message using a first physical layer configuration of the mobile communication system,
- in response to determining that a message is a non-broadcast message, adapting a configuration of the physical layer to a second configuration, wherein a first spectral efficiency of the first configuration is less than a second spectral efficiency of the second configuration, and wherein adapting includes communicating, to the other transportation vehicles, information related to adapting the configuration of the physical layer by decreasing a subcarrier spacing, and in response to receiving a plurality of adaptation proposals from the other transportation vehicles, comparing corresponding robustness of the received adaptation proposals to identify one of the received adaptation proposals having a highest robustness and adapting the second configuration of the physical layer to correspond to the one of the received adaptation proposals;
- and
- communicating non-broadcast messages using a second physical layer configuration of the mobile communication system.
A method for adapting, by a network entity, a configuration of a physical layer for communicating non-broadcast messages among a plurality of transportation vehicles in a mobile communication system, the method comprising:
- initiating communicating the non-broadcast messages using a first configuration of the physical layer having a first spectral efficiency;
- adapting the configuration of the physical layer to a second configuration having a second spectral efficiency, wherein the first spectral efficiency is less than the second spectral efficiency, and wherein adapting includes communicating, to the plurality of transportation vehicles, information related to adapting the configuration of the physical layer by decreasing a subcarrier spacing, and in response to receiving a plurality of adaptation proposals from the transportation vehicles, comparing corresponding robustness of the received adaptation proposals to identify one of the received adaptation proposals having a highest robustness and adapting the second configuration of the physical layer to correspond to the one of the received adaptation proposals;
- and
- communicating the non-broadcast messages among the plurality of transportation vehicles using the second configuration of the physical layer.
