Title:
A CHANNEL REALIZING METHOD FOR MULTI-CARRIER SYSTEM CELL
Document Type and Number:
WIPO Patent Application WO/2007/045185
Kind Code:
A1
Abstract:
A channel realizing method for multi-carrier system cell, which retains the
frequency multiplex factor to be 1 within the cell, and sets schedule indication
channels for main carrier and subcarrier while reducing the interference between
the cells at the edge of the cell by carrier grouping layout, wherein the schedule
indication channel occupying the main carrier schedules the main carrier and
the schedule indication channel schedules the subcarrier, therefore the time-frequency
resource needed by each schedule indication channel is reduced due to the schedule
indication channels set for the main carrier and the subcarrier, respectively,
which greatly reduces main carrier resource allocated to the schedule indication
channel, compared with the prior art. After setting different schedule indication
channels for the main carrier and the subcarrier, respectively, the mobile terminal
can monitor the schedule indication channels occupying corresponding carriers
on the basis of current carriers occupied by itself, therefore the load for the
mobile terminal receiving the schedule indication information is reduced,
compared with prior art.
