- FIG. 1 shows the relationship between frequencies and radio frames in the FDD scheme.
- different frequencies are used for uplink and downlink, and signal transmission in each band is performed independently.
- FIG. 2 shows the relationship between frequency and radio frame in the TDD scheme.
- TDD the same frequency is used for uplink and downlink.
- Uplink channels and downlink channels are time-division multiplexed. Therefore, although it is not strictly communicated in both directions at the same time, it is possible to realize visual communication, boost (or substantially) simultaneous communication.
- Fig. 3 shows the blending of the FDD method and the TDD method.
- consideration is given to the fact that different frequencies are used for the upper and lower links, and that the transmission timings of the upper and lower links do not coincide.
- the FDD method is preferable from the viewpoint of realizing a high transmission rate.
- some sort of filter is needed to properly separate the transmitted and received signals within the device (base station and user equipment) ( Figure 4). This is not advantageous for a terminal that needs to be downsized.
- the FDD method is described in Non-Patent Document 1, for example! /.
- Non-Patent Document 1 3GPP TS 25.201, "Physical layer-General description"
- Non-Patent Document 2 “Digital Car Telephone System Standard” Radio System Development Center, RCR STD-27, April 30, 1991
- the FDD system is adopted in the W-CDMA system, and the TDD / FDD system is adopted in a personal digital cellular (PDC) or GSM system and is operated independently! For this reason, the user must prepare a terminal (user device) for each system. If it is acceptable to mix user devices with different simultaneous transmission / reception methods, it may be possible to build a more user-friendly system, but such a proposal does not seem to have been made so far. Furthermore, even if user devices with different simultaneous transmission / reception methods are allowed to be mixed in the system, problems such as how to distinguish user devices with different simultaneous transmission / reception methods must also be solved.
- An object of the present invention is to provide a mobile communication system that allows a mixture of user apparatuses having different simultaneous transmission / reception methods, and a base station, a user apparatus, and a method used in the mobile communication system.
- a first user apparatus that performs bidirectional communication using a frequency division duplex (FDD) system
- a second user apparatus that performs bidirectional communication using a time division duplex (TDD) system
- a mobile communication system including a base station that communicates with the first and second user apparatuses is used.
- the base station uses the user identification information unique to the user apparatus, flag information indicating what the simultaneous transmission / reception method included in the uplink control channel is, or a signature that is selectively used according to the simultaneous transmission / reception system. Distinguish transmission and reception methods.
- FIG. 1 is a diagram for explaining an FDD scheme.
- FIG. 2 is a diagram for explaining the TDD scheme.
- FIG. 3 is a diagram for explaining an FDD / TDD system.
- FIG. 4 shows an FDD communication apparatus.
- FIG. 5 shows a TDD communication apparatus.
- FIG. 6 is a conceptual diagram of a mobile communication system according to an embodiment of the present invention.
- FIG. 7 is a flowchart showing an operation according to an embodiment of the present invention.
- FIG. 8 is a diagram showing a state of scheduling according to an embodiment of the present invention.
- Example 1 For convenience of explanation, the present invention is described in several embodiments. The division of each embodiment is not essential to the present invention. Two or more embodiments may be used as necessary. .
- Example 1 Example 1
- FIG. 6 shows a conceptual diagram of a mobile communication system according to an embodiment of the present invention.
- FIG. 6 shows a first user apparatus (UE1), a second user apparatus (UE2), and a base station (NodeB).
- UE1 first user apparatus
- UE2 second user apparatus
- NodeB base station
- the first user apparatus is a user apparatus that performs bidirectional communication using the FDD scheme.
- the device may be a force, fixed terminal which is typically a mobile terminal.
- the first user equipment uses the FDD method and can achieve a high data rate.
- the second user apparatus is a user apparatus that performs bidirectional communication using the TDD scheme.
- This user apparatus is also typically a mobile terminal, but may be a fixed terminal.
- the second user equipment uses the TDD method and communicates voice packets (VoIP), for example. Therefore, for the second user equipment, the data rate may be relatively low, but a small size is desirable.
- VoIP voice packets
- the base station communicates with the user apparatus while determining which radio resource is allocated to which user apparatus in the uplink and downlink.
- the base station communicates with a communication element (not shown) (for example, a core network).
- FIG. 7 shows operations performed in the base station and user apparatus according to an embodiment of the present invention.
- the user equipment transmits a random access channel (RACH) to the base station.
- RACH random access channel
- the random access channel is a channel for making an intention to request resource allocation.
- the random access channel can be transmitted at any timing by the user equipment, but it may collide with channels from other user equipment. In the event of a collision, both or one of the user devices will retransmit the channel.
- the base station grants access (access grant) and requests the user equipment to provide further information.
- the user apparatus notifies the base station of further information (setup information) according to the access permission.
- Further information includes information necessary for resource allocation, etc., and typically includes user-specific identification information (ID).
- ID user-specific identification information
- the required quality of communication desired by the user equipment and other information may be notified to the base station.
- the base station determines whether the simultaneous communication method of the user apparatus is FDD or FDD / TDD based on the information obtained from the user apparatus in the “UE determination” step! Determine. As shown in the following methods 1 to 3, there are several possible methods for determining the simultaneous communication method of the user equipment.
- Identification information power specific to user equipment FDD method or TDD / FDD method may be set.
- the identification information (identification number) of FDD user equipment is # 0000 It may be set within the range of 0 to # 09999, and the identification information (identification number) of the TDD system user device may be set within the range of # 10000 to # 19999. If the user equipment identification number is set according to these rules! /, The base station can identify what the simultaneous communication method is by referring to the user equipment identification information. The identification information of the user apparatus may be notified to the base station as setup information.
- the flag information power uplink control channel indicating whether the simultaneous communication method of the user equipment is the FDD method or the TDD / FDD method. For example, if the flag information or flag bit is “1”, the FDD method may be determined, and if the flag information or flag bit is “0”, the TDD / FDD method may be determined. This flag information may also be notified to the base station as the setup information.
- the signatures used in the random access channel may be pre-classified. For example, signatures # 1 to # 10 are reserved for FDD user equipment, and signatures # 1;! To # 20 are reserved for STDD / FDD user equipment!
- User devices select a signature according to their own method and perform random access according to what their own simultaneous communication method is.
- the base station can determine the simultaneous transmission / reception method of the user apparatus by determining which signature the user apparatus is using. According to this method, it is possible to determine the simultaneous communication method of the user device at a very early point of time of initial access.
- the base station performs scheduling and allocates radio resources to the user apparatus.
- Scheduling may be time scheduling, frequency scheduling and both time and frequency scheduling.
- Scheduling information indicating the contents of uplink and / or downlink radio resource allocation is reported to the user equipment through the downlink control channel.
- the user equipment receives the downlink data channel, transmits the uplink control channel, or transmits the uplink data channel according to the scheduling information. Send a message.
- FIG. 8 is a diagram showing a state of scheduling according to an embodiment of the present invention.
- the scheduler of the base station determines scheduling information so that resource allocation as shown in the figure is realized in the uplink and downlink.
- a radio resource may be fixedly allocated in advance for a channel that must be transmitted, such as a broadcast channel (BCH) or an uplink L1 / L2 control channel.
- BCH broadcast channel
- uplink L1 / L2 control channel For example, in the uplink L1 / L2 control channel, information indicating the downlink channel state (CQI) needs to be periodically reported to the base station.
- CQI downlink channel state
- the acknowledgment information (ACK / NACK) for the downlink data channel plays a fundamental role in retransmission control, and whether or not to retransmit is directly related to the level of throughput. Should be reported to. For this reason, it is desirable that opportunities to report CQI and delivery confirmation information to the base station are secured in advance at a high frequency. Furthermore, it is preferable to consider the broadcast channel and uplink L1 / L2 control channel for TDD user equipment so that the transmission timing does not overlap.
- the TDD scheme needs to be scheduled so that the uplink and downlink transmission timings for individual user apparatuses are different. From the viewpoint of efficiently performing such scheduling, it is preferable to plan the allocation of radio resources to the TDD user equipment first and allocate the remaining radio resources to the FDD user equipment.
