Abstract:
1. A receiving apparatus that specifies modulation and coding schemes respectively for a plurality of transmitting apparatuses and receives data that the transmitting apparatuses transmit by using the specified modulation and coding schemes, the receiving apparatus comprising: a control unit that collects information on the amount of data to be transmitted by each transmitting apparatus; selects, for each individual transmitting apparatus, a modulation and coding scheme that transports a smaller amount of data per unit resource than the other modulation and coding schemes, from among a plurality of candidates for the modulation and coding schemes; determines whether necessary resources are allocable for reception of the data to be transmitted from the transmitting apparatuses, based on the amount of the data to be transmitted and the selected modulation and coding schemes; and when the resources are unallocable, changes the currently selected modulation and coding scheme of at least one of the transmitting apparatuses to another modulation and coding scheme that transports a larger amount of data per unit resource than the currently selected modulation and coding scheme.
