Abstract
In order to enable control related to radio communication to be performed more appropriately when radio transmission schemes coexist, a radio communication apparatus according to an example aspect of the present invention includes a radio communication processing unit configured to perform communication using a first radio transmission scheme within a frequency band, wherein the radio communication processing unit is configured to perform communication using a second radio transmission scheme within a bandwidth part of the frequency band, radio resources within the bandwidth part being allocable for communication using the second radio transmission scheme.
Claims3
A method performed by a base station, the method comprising:
- performing communication using a first radio transmission scheme within a frequency band;
- performing communication using a second radio transmission scheme within a bandwidth part of the frequency band, radio resources within the bandwidth part being allocable for communication using the second radio transmission scheme;
- transmitting, to a terminal apparatus, first control information indicating the bandwidth part,
- wherein a radio resource within the bandwidth part has local identification information for locally identifying the radio resource within the bandwidth part;
- transmitting, to the terminal apparatus, the local identification information as resource allocation information,
- wherein the communication using the first radio transmission scheme and the communication using the second radio transmission scheme are uplink communication;
- and
- transmitting uplink reference signals for measurements within the bandwidth part and not transmitting the uplink reference signals outside the bandwidth part, when performing uplink communication using the second radio transmission scheme within the bandwidth part.
