Method and means for allocating time slots in a TDD system
First Claim
1. Method of allocating time slots in a time division duplex communication system, in which information is transmitted and received in predetermined time frames each having a predetermined number of time slots, wherein first and second types of time slots selected from receiving and transmitting type time slots are allocated, the first time slot of each frame is allocated as the first type of time slot, and the second time slot of each frame is allocated as the second type of time slot, said method comprising:
- determining, based on an amount of information to be transferred, whether at least one time slot following the second time slot of a current frame should be allocated as the first type of time slot, and if so, always allocating the last time slot of the current frame as the first type of time slot, whereby the last time slot of the current frame and the first time slot of a succeeding frame are the same type of time slots; and
allocating time slots following the second time slot of the current frame as additional receiving or transmitting time slots dependent on an amount of information to be transmitted and/or received, wherein if additional time slot(s) are allocated for the second type of time slot, always allocating at least the third time slot of the current frame as an additional second type time slot.

Abstract
Method and apparatus for allocating tie slots in a time division duplex communication system. First and second types of time slots selected from receiving and transmitting type time slots are allocated as the first and second time slots, respectively, in a current frame. Based on an amount of information to be transferred, it is determined whether at least one time slot following the second time slot of the frame should be allocated as the first type of time slot, and if so, the last time slot of the frame is always allocated as the first type of time slot, whereby the last time slot of the frame and the first time slot of a succeeding frame are of the same type. If an additional time slot(s) is allocated for the second type of time slot, the third slot is always designated for the second type.
