- FIG. 1 is a block diagram showing a base station 10 according to the first embodiment of the present invention.
- Base station 10 transmits system information to a mobile station using a basic broadcast channel (Primary BCH) and a secondary broadcast channel (Secondary BCH).
- the mobile station receives the basic broadcast channel and performs a cell search.
- Cell search here refers to the procedure from cell detection to acquisition of minimum system information. Since a mobile station needs to receive a basic broadcast channel when establishing a connection with a base station, the basic broadcast channel is a channel whose frequency block and timing to be transmitted by the system are determined in advance. In addition, the mobile station Various system information is acquired by receiving the secondary broadcast channel.
- the base station 10 includes a system information generation unit 101, a system information division unit 103, and an encoding unit 105.
- a modulation unit 107 a multiplexing unit 109, a serial-parallel conversion unit 111, a scramble code generation unit 113, a scramble code multiplication unit 115, and a synthesis unit 117.
- System information generation section 101 generates system information to be transmitted to a mobile station.
- This system information includes system information necessary for cell search and system information other than system information necessary for cell search.
- the following information exists as system information other than the system information necessary for cell search.
- Mobile station timer value • Mobile station timer value, parameter value ' ⁇ ' Mobile station cell selection operation period, mobile station to base station reception level reporting period, mobile station initial transmission power, etc.
- Neighboring cell information ' ⁇ ⁇ Cell ID of neighboring cells, system bandwidth, broadcast channel bandwidth, number of transmitting antennas, timing information (timing deviation between base stations), transmission power, number of sectors, etc.
- Own cell channel configuration information ' ⁇ Information such as paging channel other than broadcast channel, L1 / L2 control channel, etc.

Information to be transmitted). At this time, system information division section 103 may include channel information (frequency block and timing) of the secondary broadcast channel in the information transmitted on the basic broadcast channel.
- System information necessary for cell search is encoded in encoding section 105a and modulated in modulation section 107a. Further, system information other than information necessary for cell search is encoded by the encoding unit 105b and modulated by the modulation unit 107b.
- the modulated system information is multiplexed into a basic broadcast channel and a secondary broadcast channel by a multiplexing unit 109, and is serial-parallel converted by a serial-to-parallel conversion unit 111, and is N-numbered on the frequency axis. It becomes an information symbol series.
- the N information symbol sequences on the frequency axis that have been serial-parallel converted are arranged on the frequency axis.
- Combining section 117 multiplexes a sequence of symbols having a sequence length of N multiplied by a scramble code onto a specific subcarrier corresponding to a synchronization signal of N subcarriers.
- the inverse Fourier transformer (IFFT) converts N symbols into orthogonal multicarrier signals.
- the CP (cyclic prefix) adder inserts CP into this multicarrier signal at every Fourier target time. Then, the base station 10 outputs the multicarrier signal output from the CP adding unit as a radio signal.
- the base station 10 may transmit the basic broadcast channel in a short cycle and transmit the secondary broadcast channel in a long cycle. Since the basic broadcast channel must be received first, it is preferable to transmit it in a short period in order to reduce the delay until reception. Note that the amount of information on the basic broadcast channel is small compared to the amount of information on the secondary broadcast channel, so the effect of overhead on transmission in a short cycle is small. On the other hand, since the mobile station does not need to receive the secondary broadcast channel in a hurry, it can reduce overhead by transmitting in a long cycle. [0026] Further, by using the same scramble code in the base station, signals from adjacent sectors do not interfere with each other, and are synthesized when signals transmitted from each sector are received (soft converter).
- Soft-combining When using soft compiling, soft combining may be used for both the basic and secondary broadcast channels. In addition, soft compiling may be used only for the basic broadcast channel, because the basic broadcast channel information is important and contains a lot of common information in the base station. By using soft compiling for the channel, the combined reception effect is effectively increased, and soft combining is applied only to the secondary broadcast channel. If the information power common to the base station is included in the secondary broadcast channel, the combined reception effect is increased.
- the basic broadcast channel may be divided into a portion for soft combining and a portion not for soft combining. For example, only the information common within the base may be soft combined using the same scramble code.

- Secondary broadcast channel receiving section 201b receives the secondary broadcast channel using the channel information of the extracted secondary broadcast channel, and extracts system information other than the system information necessary for cell search.
- the base station since the base station transmits system information necessary for cell search using the basic broadcast channel, the mobile station receives only the basic broadcast channel during cell search. do it. Therefore, the information that the mobile station receives on the basic broadcast channel. The information is reduced and the cell search time can be reduced.
- the broadcast channel is divided into the basic broadcast channel and the secondary broadcast channel.
- the system information transmitted through the secondary broadcast channel is secondary-reported. It may be further divided into channels and shared data channels.
- one broadcast channel may be divided into a plurality of blocks (basic broadcast channel block and secondary broadcast channel block).

Then, it transmits to the mobile station using a plurality of broadcast channels or a plurality of broadcast channel blocks. The mobile station receives only necessary ones of a plurality of broadcast channels or a plurality of broadcast channel blocks. For example, when a mobile station moves from sector to sector within the same base station, it is only necessary to receive sector-specific information that does not need to receive information specific to the base station.

- the information specific to the base station is the same information between different sectors in the base station, so the same scramble code is generated in the base station.
- different scramble codes are used for sector-specific information, and base station-specific information that does not include sector-specific information uses the same scramble code within the base station.
- signals from adjacent sectors do not interfere, and are synthesized when signals transmitted from each sector are received (soft combining (soft combining (soft -combining)).
- the pilot channel corresponding to the radio resource to be soft-combined may be shared between sectors. For example, by providing a pilot channel control unit as shown in Fig. 6, the pilot channel is shared between sectors. By doing so, the gain of soft combining can be increased.
- the pilot channel common between sectors only a part of the pilot channel in the frequency block may be made common between sectors, and the other part may be made independent between sectors. In this way, by dividing the inter-sector common pilot and the inter-sector independent pilot, it is possible to divide the processing common to each sector and the individual processing for each sector. Individual processing for each sector includes mobile station reception measurement and L1 / L2 control channel reception.
- the nanochannels may be orthogonal between sectors.
- a mobile station can receive orthogonal pilot channels, and obtain and combine the pilot channels.
- CDD Cyclic Delay Diversity
- the same scrambling code may be used in the upper station for information unique to the upper station. In this way, soft combining between base stations becomes possible.
- different scramble codes may not necessarily be used between the sectors to be combined or between base stations. In this case, it is also possible for the mobile station to independently receive a plurality of broadcast channels (in which the same information is transmitted) and combine them. This makes it possible to obtain the same effect as soft compiling (however, the effect of synthesis is smaller than that of soft compiling).
- the mobile station receives only the necessary broadcast channel, so that the information received by the mobile station on the broadcast channel is reduced, and the power consumption is reduced. Reduction and high-speed cell switching become possible. For example, whether the sector has changed can be determined from the cell ID detected at the time of cell search and the neighboring cell information.
- signals transmitted from a plurality of sectors can be combined and received (without interfering with each other), and reception with high quality is possible. .
- the transmission power of the broadcast channel or the radio resource block can be reduced.
