Abstract:
1. A communication apparatus comprising: a plurality of antennas; a setting unit for setting a communication mode for different one or more counterpart communication apparatuses to a non-spatial multiplexing mode or a spatial multiplexing mode; and a transmission processing unit for processing a transmitting signal to the different one or more counterpart communication apparatuses to output the processed signal to said plurality of antennas, on the basis of said set communication mode, wherein said setting unit switches the setting of the communication mode for said different one or more counterpart communication apparatuses from said non-spatial multiplexing mode to said spatial multiplexing mode, based at least in part on a capability of a communication system comprising the communication apparatus and said different one or more counterpart communication apparatuses, and a minimum reserved traffic rate (MRTR) associated each of at least some of said different one or more counterpart communication apparatuses, wherein said setting unit switches the setting of the communication mode for said different one or more counterpart communication apparatuses from said non-spatial multiplexing mode to said spatial multiplexing mode, in response to determining that a ratio of a radio resource reserved for service flows associated with each of at least some of said different one or more counterpart communication apparatuses relative to all radio resources exceeds a threshold value.
