Communication system, base station, terminal, and communication method

摘要

A multiservice is implemented by connecting one base station and one terminal via one wireless link.;There is provided communication control means 2-1 that performs communication in compliance with an OFDMA scheme having traffic channels including first sub-channels for containing information showing enabled or disabled sub-channels and second sub-channels for storing data pertaining to services in correspondence with the first sub-channels, that allocates a plurality of first sub-channels to a plurality of services, respectively, and that connects one base station to one terminal via one wireless link, thereby establishing communication pertaining to the plurality of services.

1. A communication system comprising:
communication control means that allocates one wireless link between one base station and one terminal and that adds, in the one wireless link, communication including, in addition to a first service provided by communication initially performed, a second service differing from the first service, wherein the first service has a first priority and the second service has a second priority differing from the first priority, wherein communication is performed in compliance with an OFDMA scheme having traffic channels including first sub-channels including information showing enabled or disabled sub-channels and second sub-channels storing data pertaining to the services in correspondence with the first sub -channels, wherein, when the communication control means adds the communication including, in addition to the first service provided by the initially-performed communication, the second service differing from the first service, the communication control means allocates, in addition to a first sub-channel allocated to the initially-performed communication, another first sub-channel differing from the first sub-channel allocated to the initially-performed communication, wherein the communication control means associates, on the basis of priorities corresponding to the respective services, the priorities with the first sub-channels and allocates the second sub-channels on the basis of the priority.
