- a collision permissible channel is a channel that does not need to be scheduled at the base station before transmission
- a collision non-permissible channel is a channel that needs to be scheduled at the base station before transmission.
- the collision-acceptable channels include one or more of (A1) a high-speed access channel, (A2) a reserved channel, and (A3) an uplink synchronization channel.
- the collision non-permission channel includes one or more of (B1) uplink shared data channel and (B2) uplink shared control channel.
- the uplink shared data channel includes traffic data and / or layer 3 control messages.
- the control message contains information related to handover and is necessary for retransmission control. Important information may be included.
- the uplink shared data channel is assigned one or more frequency chunks according to scheduling in the time domain or both time and frequency domains. In this case, resource allocation is planned at the base station so that users associated with better channels (channels) can preferentially transmit packets in the time domain or both time and frequency domains. (Scheduled).
- the number of frequency chunks to be allocated is determined depending on the data rate, data size, etc. that the mobile station intends to transmit. Relatively low, requires only data rate, and if there are multiple users, one chunk may be shared by multiple users.
- one chunk can be used by one user. Also, one user can use multiple chunks. When one chunk is shared by multiple users, some multiplexing is performed so that the channels of multiple users are orthogonal to each other within the chunk. For example, a single FDMA or distributed FDMA may be performed within that chunk.
- TTI is a unit of information transmission, and some control channel is added as overhead for each TTI.
- the length of the transmission time interval may be changed adaptively. Increasing the TTI length reduces the frequency of overhead transmission and improves the traffic data transmission efficiency.
- shortening the TTI can suppress a significant deterioration in throughput.

- FFS layer 2 control messages
- resource allocation is planned at the base station so that users associated with better channels (channels) can preferentially transmit packets.
- scheduling depending on the superiority or inferiority of the channel state is not essential (however, as will be described later, some link adaptation may be performed for the shared control channel). ).
- the base station allocates chunks and TTIs to each mobile station and performs scheduling to avoid contention for shared control channels .
- the base station performs scheduling depending on the number of users. In order to keep the packet error rate low, it is desirable to perform highly accurate transmission power control. In addition, it is desirable to improve the quality of received packets by transmitting the uplink shared control channel over a wide frequency range and obtaining the frequency diversity effect.
- the control information for changing the scheduling content of the uplink shared data channel is transmitted in order to notify the base station of the buffer size and Z or transmission power of the mobile station. It is.
- This control information may be transmitted regularly or irregularly. For example, it may be transmitted from the mobile station when the buffer size and / or transmission power changes.
- the base station may change the scheduling content according to such a change in the situation of the mobile station.
- the buffer size and transmission power status may not be able to be expressed with an information amount of about 10 bits, for example.
- Control information for scheduling the downlink shared data channel is transmitted to notify the base station of downlink channel quality information (CQI: channel quality indicator).
- CQI channel quality information
- the CQI may be a received SIR measured by a mobile station, for example. This information may be sent regularly or irregularly. For example, it may be reported to the base station when the channel quality changes.
- This control information may be expressed with an information amount of about 5 bits, for example.
- channel estimation is performed by distinguishing between mobile stations that move at high speed and mobile stations that do not move at high speed.
- a first pilot channel for a mobile station in a normal communication environment that does not move at high speed, and a second pilot channel for a mobile station moving at a high speed that can reach several hundred kilometers per hour are provided.
- the first pilot channel is mapped to a predetermined number (typically two places before and after the TTI) for each TTI.
- the first pilot channel may be used for channel estimation and received signal quality measurement. Synchronization timing may be captured using the first pilot channel.
- the second pilot channel is mapped to zero or more locations in the TTI depending on the mobile station's moving speed and propagation path conditions. This may not be necessary depending on the moving speed of the mobile station.
- the first pilot channel is always Since the second pilot channel may not be transmitted, it is a supplemental pilot channel.
- the mapping position and the number of mappings for the first and / or second pilot channels may be selected as appropriate from the predetermined mapping candidates.
- FIG. 10 shows an example of pilot channel mapping when only the first pilot channel is included in the TTI.
- eight (data) symbols are included in one TTI, and the first pilot channel is assigned to the first and last two symbols.
- CP indicates a guard interval with a cyclic prefix.
- the parts indicated by data, data, ... represent the data of the collision-allowed or collision-non-permissible channel
- FIG. 11 shows an example in which two first pilot channels and one second pilot channel are mapped in the cage.
- the second pilot channel is mapped in the middle of the trap (for example, the fourth symbol).
- the pilot channel (first pilot channel) is commonly used for the uplink shared control channel and the uplink shared data channel. This pilot channel is used for CQI measurement and channel estimation. This pilot channel is mapped to the first and last symbols in the TTI.
- the supplementary pilot channel (second pilot channel) may or may not be assigned depending on the channel conditions of each user. In the example shown, it is not assigned. Multiple shared control channels for multiple users in the same symbol are multiplexed by CDMA and by Z or F DMA (including localized and distributed), thereby providing a frequency diversity effect.
- the pilot channel and the uplink shared control channel include information on each user multiplexed in a chunk transmitting them, and the control information on each user is mapped to be orthogonal to each other by FDMA or the like. More specific mapping examples will be described later.

- the pilot channel may be multiplexed so as to be orthogonal to each user's signal by the CDMA method.
- both the pilot channel and the uplink shared control channel can be multiplexed by the FDMA method or by the CDMA method.
- mapping example 1 user A, who can use two chunks, uses the two chunks to code-multiplex and transmit the uplink shared control channel. This mapping example is advantageous when the amount of data transmission related to user A is large.
- mapping example 2 user A who can use two chunks uses a single chunk to code-multiplex and transmit a shared control channel. In this example, fairness among users is maintained.
- mapping example 3 two chunks are used with half the transmission power per user A power chunk that can use two chunks, and the shared control channel is code-multiplexed and transmitted. In this example, fairness among users is maintained.
- a plurality of uplink shared control channels for a plurality of users may be multiplexed by the FDM method, by the CDM method, or by both the FDM and CDM methods, and the channels for each user may be orthogonal to each other.
- the base station notifies the mobile station of information (mapping information) on how the shared control channels of various users are multiplexed using the downlink shared control channel.
- the mobile station transmits an uplink shared control channel according to the notified instruction content.
- the orthogonality by the CDM system is more likely to be broken due to multipath interference, reception timing shift, and the like, compared to the orthogonality by the FDM system. For this reason, in one embodiment of the present invention, if the number of users to be multiplexed is equal to or less than a predetermined number N, the FDM method is used for multiplexing.

- FIG. 13C shows a state in which uplink shared control channels of a plurality of users are multiplexed by distributed FDMA and CDMA systems. If the number of users is 4 or less, the uplink shared control channel is multiplexed by the distributed FDMA system, and if the number of users is 5 or more, it is multiplexed by both the FDMA and CDMA systems.

In this way, the base station can acquire control information other than the essential control information for all users by examining received signals in a relatively narrow dedicated frequency band, and simplifies signal processing at the base station.

It is.
- Each of the modulation and encoding units performs data modulation on the channel input thereto using the instructed modulation scheme, and channel-encodes using the instructed encoding scheme.
- the modulation scheme and coding scheme used for each channel may be different for each channel, or the same scheme may be used for two or more channels.
- the modulation method or coding method may be set to be fixed and unchanged.
- Multiplexer 259 multiplexes each channel to create and output a shared control channel.
- Link adaptation methods include Adaptive Modulation and Coding (AMC) and Transmission Power Control (TPC) control.
- AMC Adaptive Modulation and Coding
- TPC Transmission Power Control
- Fig. 26 shows the principle of adaptive modulation and coding (AMC) control, and it is necessary to change the modulation method and / or coding method adaptively according to the channel condition. It is intended to achieve quality. More specifically, if the transmission power from users (mobile stations) 1 and 2 is the same, the channel condition for user 1 far from the base station is expected to be bad (bad CQI). The modulation multilevel number is set to be small and / or the channel coding rate is set to be small. In the example shown in the figure, QPSK is used as the modulation scheme for user 1 and 2 bits of information are transmitted per symbol.
- AMC adaptive modulation and coding
- the user 2 close to the base station is expected to have good channel conditions (good CQI), and the modulation multilevel number is set large and / or the channel coding rate is set large.
- good CQI good channel conditions
- 16QAM is used as the modulation method for user 2 and 4 bits of information is transmitted per symbol.
- the required quality can be achieved by increasing the reliability for users with poor channel conditions, and the throughput can be improved while maintaining the required quality for users with good channel conditions.
- Multiple combinations of modulation schemes and encoding schemes are prepared in advance, and the number of transmission control bits can be saved by communicating information (MCS number) indicating the combination.
- MCS number communicating information
- Such MCS numbers may be the same as those used for the shared data channel, may be prepared separately for the shared control channel, or a part of those provided for the shared data channel may be used.
- transmission of the shared control channel is not required to be as fast as the shared data channel.
- information such as the modulation method, coding method, number of symbols, etc. applied to that channel is required, so that information is notified to the receiving side by some means. It is necessary to. Also, since the number of bits that can be transmitted per symbol differs depending on whether the channel condition is good or not, information can be transmitted with a small number of symbols if the channel condition is good, but otherwise a large number of symbols is required. .
- the MCS used for the shared control channel may be determined according to the number of control bits required for transmission. In other words, when a large number of control bits must be transmitted, a large MCS number (a large number of modulation levels and a large channel code rate) may be used. In addition, a small MCS number (a small modulation multi-level number and a small channel coding rate) may be used if only a small number of bits and control bits are transmitted.
- FIG. 28 shows an example of an uplink frame configuration.
- the shared control channel, pilot channel, and shared data channel are multiplexed by the time division multiplexing (TDM) method.
- the shared control channel mainly includes information used for demodulating the shared data channel and is also called an L1L2 signaling control channel.
- L1L2 signaling control channel In the situation shown in (A), the uplink channel state is good and a relatively large MCS number is used for the shared control channel. Therefore, the period occupied by the L1L2 signaling control channel is relatively short.
- the uplink channel state is better than (A), which is good enough to allocate resources by scheduling. In this case, a relatively small MCS number is used for the shared control channel.
- the modulation scheme and channel coding scheme are kept constant, and known combinations are used on the transmission side and the reception side. Therefore, it is not necessary to separately notify the modulation method and the like in order to demodulate the channel under transmission power control.
- the mobile station estimates the uplink transmission power using the propagation loss L and transmits the shared control channel using that power.
- the propagation loss L is expressed by the difference between the transmission power P at the base station and the reception power P at the mobile station. Notification t r broadcasted from the base station
- FIG. 31 is a flowchart showing another example of the transmission power control method. This method is called “CQI-based TPC” for convenience.
- the mobile station transmits an uplink pilot channel to the base station, and the base station measures CQI based on the reception level of the uplink pilot channel.
- the base station refers to a table as shown in Fig. 27 and determines the MCS number to be used for the uplink shared data channel based on the quality of CQI.
- the correspondence between the MCS number of the shared data channel and the transmission power applied to the shared control channel is known by the base station and mobile station.
- the determined content is the downlink shared control channel, and the MCS number is notified to the mobile station.
- the mobile station derives the transmission power corresponding to the shared control channel according to the notified MCS number, and transmits both the shared data channel and the shared control channel to the base station.
- FIG. 32 shows an example of combination of control information and transmission power control method.
- the shared control channel may include control information other than the essential control information and the essential control information.
- the essential control information includes information indicating the MCS and the like used for the uplink shared data channel, and the MCS and the like are informed to the base station power mobile station.
- the correspondence between the transmission power of the shared control channel and the MCS number of the shared data channel can be set in advance. Therefore, since the mobile station can derive the transmission power of the uplink shared control channel from the notified MCS number, the control bit for controlling the transmission power of the uplink shared control channel is not included in the downlink shared control channel. (It is unnecessary). Since essential control information cannot be demodulated unless it is properly received, the shared control channel containing essential control information should be transmitted with high quality. Therefore, it is desirable that CQI-based TPC be performed with higher accuracy than open-loop TPC.
- AMC control is performed even for the shared control channel.
- the shared control channel requires less high throughput than the shared data channel.
- the MCS can be selected according to the channel state, and the quality of the shared control channel can be improved. Can be achieved.

- pilot channels are regularly transmitted on the uplink.
- the base station that has received the pilot channel measures uplink channel conditions and derives channel quality information (CQI).

- L1L2 and transmission power (P) etc. are included.
- Various parameters are in table format, for example
- Channel quality information CQI, modulation and coding rate information MCS, transmission period T and transmission power P are related to each other, and at least
- channel quality information CQI Other parameters are uniquely derived from the channel quality information CQI.
- poor channel quality CQI is due to MCS with a small number of transmitted bits, long transmission period T and large
- channel quality information CQI channel quality information
- modulation and coding rate information MCS modulation and coding rate information
- transmission period ⁇ transmission period
- the transmission method for the uplink shared control channel is determined.
- the frame configuration shown in Fig. 28 (A) is adopted for users with good channel conditions, and conversely the frame configuration shown in Fig. 28 (B) for users with poor channel conditions.
- Information indicating the determined radio parameters is reported to the mobile station through the shared control channel.
- the information indicating the radio parameters may or may not represent all the above parameters individually.
- a radio parameter table is commonly used by the base station and the mobile station, only the MCS is notified to the mobile station, and the mobile station can derive other parameters from the MCS.
- the CQI measured at the base station may be notified to the mobile station. In any case, it is only necessary that the mobile station can appropriately know the radio parameters determined by the base station.
- the MCS determined from the reception quality CQI of the uplink channel is notified to the mobile station.
- the mobile station sets various radio parameters according to the notified instruction content. More specifically, the MCS is set by the shared control channel generation unit 233 in FIG. 23 (adaptive modulation and channel coding units 255-258 in FIG. 25). The transmission period T of the shared control channel is as shown in Fig. 23
- the uplink shared control channel is transmitted with appropriately adjusted radio parameters.
- the base station does not need to know the transmission power of the uplink shared control channel. Big sending This is because the reception quality only increases as the signal is transmitted with the transmission power. Therefore, information indicating how much the transmission power of the shared control channel is or how it changes does not have to be transmitted between the base station and the mobile station. On the other hand, the MCS and transmission period T of the shared control channel are received appropriately if they are unknown.
