Wireless packet communication method and system for transmitting packets between base station and radio terminal station
First Claim
1. A wireless packet communication system including at least one radio terminal station, and a base station for multiplexing packets to be transmitted using a plurality of subcarriers and for sending the multiplexed packets to said at least one radio terminal station, said system comprising:
- means provided in said base station for simultaneously sending reference signals on said subcarriers with the same level to said at least one radio terminal station;
report means provided in said at least one radio terminal station for reporting to said base station received conditions of the reference signal of each subcarrier or of each subband corresponding to a frequency band occupied by a plurality of subcarriers; and
means provided in said base station for allocating the subcarrier or the subband to each of said packets to be transmitted depending upon the reported received conditions of said subcarrier or said subband, said allocation being performed in a transmission order of said packets.

Abstract
A wireless packet communication system includes at least one radio terminal station, and a base station for multiplexing packets to be transmitted using a plurality of subcarriers and for sending the multiplexed packets to the at least one radio terminal station. The system has a unit provided in the base station for simultaneously sending reference signals on the subcarriers with the same level to the at least one radio terminal station, a report unit provided in the at least one radio terminal station for reporting to the base station received conditions of the reference signal of each subcarrier or of each subband corresponding to a frequency band occupied by a plurality of subcarriers, and a unit provided in the base station for allocating the subcarrier or the subband to each of the packets to be transmitted depending upon the reported received conditions of the subcarrier or the subband, the allocation being performed in a transmission order of the packets.

12. A communication method in a wireless packet communication system including at least one radio terminal station, and a base station for multiplexing packets to be transmitted using a plurality of subcarriers and for sending the multiplexed packets to said at least one radio terminal station, said method comprising the steps of:
-
simultaneously sending from said base station reference signals on said subcarriers with the same level to said at least one radio terminal station;
reporting from said at least one radio terminal station to said base station received conditions of the reference signal of each subcarrier or of each subband corresponding to a frequency band occupied by a plurality of subcarriers; and
allocating in said base station the subcarrier or the subband to each of said packets to be transmitted depending upon the reported received conditions of said subcarrier or said subband, said allocation being performed in a transmission order of said packets. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
