Wireless communication method with packet scheduling

Abstract

To reduce power consumption of a mobile station, this invention provides a wireless communication method for communicating between a base station and a plurality of terminals using a plurality of channels, the channels being slots obtained by dividing frequency-divided carriers by time, in which the base station allocates a set of the channels which is composed of a plurality of neighboring carriers and/or a plurality of successive slots for the each terminal, and the base station allocates at least one of the channels included in the channel sets for packet transmission the terminals.

What is claimed is: 
     
         1 . An information processing device implemented in a wireless terminal which communicates with a base station, the base station and a plurality of terminals communicating by using M channels, information indicating N (N is integer, N<M) channels to be allocated to each terminal is transmitted from the base station,
 the information processing device comprising:   a receiver which receives an input of the information;   a controller which judges, among the M channels, whether each of the N channels is to be monitored or not on the basis of the information;   a monitor which monitors states of the N channels to be monitored on the basis of the judging; and   a transmitter which outputs, to the base station, channel information related to only the monitored N channels and does not output, to the base station, channel information related to channels other than monitored N channels.   
     
     
         2 . The information processing device according to  claim 1 , wherein:
 the channels are configured to provide a plurality of time slots for each frequency region,   the information indicates time information related to time slots to be monitored, and   the monitor performs monitoring of the time slots corresponding to the time information.   
     
     
         3 . The information processing device according to  claim 1 , wherein:
 the channels are configured to provide a plurality of frequency regions for each time slot,   the information indicates frequency information related to at least one of the frequency regions to be monitored, and   the monitor performs monitoring of the at least one frequency region corresponding to the frequency information.   
     
     
         4 . An information processing device implemented in a wireless terminal which communicates with a base station, wherein information to judge whether a part of channels, less than a total number of the plurality of channels, is to be monitored or not is transmitted from the base station to each terminal,
 the information processing device comprising:   a receiver which receives an input of the information as to whether the part of the channels are to be monitored or not;   a monitor which monitors states of only the part of channels to be monitored on the basis of the information transmitted from the base station; and   a transmitter which outputs, to the base station, channel information related to states of only the part of channels to be monitored, and does not output channel information related to states of channels other than the channels to be monitored.   
     
     
         5 . The information processing device according to  claim 4 , wherein:
 the channels are configured to provide a plurality of time slots for each frequency region,   the information indicates time information related to time slots to be monitored, and   the monitor performs monitoring of the time slots corresponding to the time information.   
     
     
         6 . The information processing device according to  claim 4 , wherein:
 the channels are configured to provide a plurality of frequency regions for each time slot,   the information indicates frequency information related to at least one of the frequency regions to be monitored, and   the monitor performs monitoring of the at least one frequency region corresponding to the frequency information.   
     
     
         7 . An information processing device implemented in a wireless terminal which communicates with a base station, the base station and a plurality of terminals communicating by using M channels, wherein information indicating N (N is integer, N<M) channels to be allocated to each terminal is transmitted from the base station,
 the information processing device comprising:   a part for receiving an input of the information;   a part for judging, among the M channels, whether each of the N channels is to be monitored or not on the basis of the information;   a part for monitoring states of the N channels to be monitored on the basis of the judging; and   a part for outputting, to the base station, channel information related to only the monitored N channels and not outputting, to the base station, channel information related to channels other than monitored N channels.   
     
     
         8 . The information processing device according to  claim 7 , wherein:
 the channels are configured to provide a plurality of time slots for each frequency region,   the information indicates time information related to time slots to be monitored, and   the part for monitoring performs monitoring of the time slots corresponding to the time information.   
     
     
         9 . The information processing device according to  claim 7 , wherein:
 the channels are configured to provide a plurality of frequency regions for each time slot,   the information indicates frequency information related to at least one of the frequency regions to be monitored, and   the part for monitoring performs monitoring of the at least one frequency region corresponding to the frequency information.
