Method, base station and mobile station for timeslot selection and timeslot assignment
First Claim
1. A timeslot selection method of selecting a transmitting timeslot used by a mobile station in a wireless packet transmission system where said mobile station communicates with a base station, said timeslot selection method comprising the steps of:
- obtaining a propagation loss;
receiving an occupation state and an interference amount of an uplink timeslot from said base station;
obtaining a desired wave power from said propagation loss;
obtaining a ratio between said desired wave power and said propagation loss for said uplink timeslot in which said occupation state is idle; and
selecting said transmitting timeslot by using said ratio between said desired wave power and said propagation loss among uplink timeslots.

Abstract
A timeslot selection method is provided. The timeslot selection method includes the steps of: obtaining a propagation loss; receiving an occupation state and an interference amount of an uplink timeslot; obtaining a desired wave power from the propagation loss; obtaining a ratio between the desired wave power and the propagation loss for the uplink timeslot in which the occupation state is idle; and selecting the transmitting timeslot by using the ratio. In addition, a timeslot assignment method in which there are a plurality of TDD boundaries each of which is a boundary between at least an uplink timeslot and at least a downlink timeslot in a frame is provided. Furthermore, a timeslot assignment method is provided, in which assignment is carried out according to a service class included in a QoS request.
