Abstract
The invention relates to an improved radio resource allocation performed by a vehicular mobile terminal. The vehicular mobile terminal determines whether to determine radio resources based on the location of the vehicular mobile terminal or not, based on information received from an entity of the communication system. In case the radio resources are to be selected based on the location of the vehicular mobile terminal, the vehicular mobile terminal determines the location of the vehicular mobile terminal, and determines radio resources for communication with at least the second mobile terminal, based on the determined location of the vehicular mobile terminal.
Claims11
A communication apparatus, comprising:
- reception circuitry, which, in operation, receives parameter information in a cell in which the communication apparatus is located;
- and
- control circuitry, which is coupled to the reception circuitry and which, in operation, determines, based on the parameter information, whether to use radio resources which correspond to a geographical location of the communication apparatus,
- wherein, responsive to the parameter information indicating to use radio resources which correspond to a geographical location of the communication apparatus, the control circuitry:
- determines the geographical location of the communication apparatus,
- identifies a location subsection in which the communication apparatus is geographically located based on the parameter information, wherein the parameter information includes a first parameter indicative of a length of the location subsection, a second parameter indicative of a width of the location subsection, a third parameter indicative of a number of location subsections with respect to the length in longitude into which a location section is divided, and a fourth parameter indicative of a number of location subsections with respect to the width in latitude into which the location section is divided, wherein the first to fourth parameters are dynamically signaled from a radio base station,
- dynamically determines radio resources, which correspond to the identified location subsection in which the communication apparatus is geographically located, based on the length and width of the location subsection indicated by the first and second parameters and the numbers of location subsections into which the location section is divided with respect to longitude and latitude indicated by the third and fourth parameters, and
- performs communication using the determined radio resources.
A method performed by a communication apparatus, the method comprising:
- receiving parameter information in a cell in which the communication apparatus is located;
- determining, based on the parameter information, whether to use radio resources which correspond to a geographical location of the communication apparatus;
- responsive to the parameter information indicating to use radio resources which correspond to a geographical location of the communication apparatus,
- determining the geographical location of the communication apparatus,
- identifying a location subsection in which the communication apparatus is geographically located based on the parameter information, wherein the parameter information includes a first parameter indicative of a length of the location subsection, a second parameter indicative of a width of the location subsection, a third parameter indicative of a number of location subsections with respect to the length in longitude into which a location section is divided, and a fourth parameter indicative of a number of location subsections with respect to the width in latitude into which the location section is divided, wherein the first to fourth parameters are dynamically signaled from a radio base station,
- dynamically determining radio resources, which correspond to the identified location subsection in which the communication apparatus is geographically located, based on the length and width of the location subsection indicated by the first and second parameters and the numbers of location subsections into which the location section is divided with respect to longitude and latitude indicated by the third and fourth parameters, and
- performing communication using the determined radio resources.
