Wireless communication base station apparatus, wireless communication mobile station apparatus, wireless communication method, and wireless communication system
View Patent ↗A wireless communication method and a wireless communication system wherein any communication interruption caused by changing RRB arrangement information can be avoided. In ST 301 , Node B ( 100 ) transmits informative information including the RRB arrangement information and RRB arrangement version. In ST 302 , UE ( 200 ) holds the RRB arrangement information and RRB arrangement version included in the informative information received from Node B ( 100 ). In ST 303 , UE ( 200 ) creates CQI information including both a CQI report value, which is calculated by use of the held RRB arrangement information, and the held RRB arrangement version. In ST 304 , UE ( 200 ) transmits the CQI information to Node B ( 100 ). In ST 305 , Node B ( 100 ) performs a scheduling based on the RRB arrangement information determined from the RRB arrangement version included in the received CQI information. In ST 306 , Node B ( 100 ) transmits the scheduling information to UE ( 200 ).
1. A wireless communication base station apparatus comprising:
a managing section that manages arrangement information and an arrangement version as an index of the arrangement information, the arrangement information representing an arrangement of a distributed channel where frequency and time are assigned in a distributed manner and a localized channel where frequency and time are assigned in a concentrated manner;
a broadcast information creating section that creates, every time the arrangement information changes, broadcast information including the arrangement information and the arrangement version; and
a transmitting section that transmits the broadcast information,
wherein the broadcast information creating section creates the broadcast information including one of the arrangement information and the arrangement version in an adjacent cell.
