Time slot allocating apparatus, time slot allocating method thereof, memories and programs, mobile communication system and operating method
First Claim
1. A time slot allocating apparatus in a scheme applying a common frequency band to up/downlinks and using the frequency band in a first area and a second area, the time slot allocating apparatus being located in respective areas, the apparatus comprising:
- means for, when in the first area and the second area either one link of the up/downlinks is allocated to a first mobile station in the first area, allocating the other link having a time slot number equal to that of a time slot allocated to the first mobile station and being different from the link of the first mobile station, to a second mobile station in the second area.

Abstract
Concerned is time slot allocation in the CDMA-TDD scheme. A time slot of an uplink (UL) is allocated to a mobile station MS1 in cell 1. At this time, a time slot of a downlink (DL) having the same time slot number as that of the foregoing time slot is allocated to a mobile station MS2 in an adjacent cell 2 without avoiding the allocation. If there can occur deterioration of communication quality a process of allocating another time slot or the like will be performed as in the case of a mobile station MS2-1.
