MOBILE COMMUNICATIONS SYSTEM, BASE STATION, USER APPARATUS, AND METHOD
First Claim
1. A mobile communications system, comprising:
- a first user apparatus which conducts a two-way communication using frequency division duplex (FDD);
a second user apparatus which conducts a two-way communication using time division duplex (TDD); and
a base station which communicates with the first and second user apparatuses, whereinthe base station distinguishes among simultaneous transmitting and receiving schemes of the user apparatuses based on user-apparatus specific user identification information, flag information showing a simultaneous transmitting and receiving scheme included in an uplink control channel;
or signatures, a proper use of which is made according to the simultaneous transmitting and receiving scheme.

Abstract
A mobile communications system is disclosed. The mobile communications system includes: a first user apparatus for two-way communicating using frequency division duplex (FDD); a second user apparatus for two-way communicating using time division duplex (TDD); and a base station for communicating with the first and second user apparatuses. The base station distinguishes among the simultaneous transmitting and receiving schemes of the user apparatuses based on user-apparatus specific user identification information, flag information showing a simultaneous transmitting and receiving scheme that is included in an uplink control channel, or signatures, a proper use of which is made according to the simultaneous transmitting and receiving scheme.

4. A base station which is used in a mobile communications system, the base station communicating with a first user apparatus which conducts a two-way communication using frequency division duplex (FDD), and a second user apparatus which conducts a two-way communication using frequency division duplex/time division duplex (FDD/TDD), wherein
a simultaneous transmitting and receiving scheme of the user apparatuses is distinguished based on user-apparatus specific user identification information, flag information showing a simultaneous transmitting and receiving scheme included in an uplink control channel, or signatures, a proper use of which is made according to the simultaneous transmitting and receiving scheme.

7. A user apparatus which is used in a mobile communications system having a base station which communicates with user apparatuses of different simultaneous transmitting and receiving schemes, wherein an uplink control channel is transmitted which includes flag information indicating whether each of the simultaneous transmitting and receiving schemes is frequency division duplex (FDD) or frequency division duplex/time division duplex (FDD/TDD).
-
8. A method which is used in a mobile communications system which includes a first user apparatus which conducts a two-way communication using frequency division duplex (FDD), a second user apparatus which conducts a two-way communication using time division duplex (TDD), and a base station which communicates with the first and second user apparatuses, comprising the steps of:
-
by the base station, distinguishing among simultaneous transmitting and receiving schemes of the user apparatuses based on user-apparatus specific user identification information, flag information showing a simultaneous transmitting and receiving scheme included in an uplink control channel;
or signatures, a proper use of which is made according to the simultaneous transmitting and receiving scheme; andby the base station, planning to allocate a radio resource to the second user apparatus, and allocating another radio resource to the first user apparatus; and reporting, to the first and second user apparatuses, scheduling information showing a status of allocating of the radio resources.
