DESCRIPTION

Assignment of uplink confirmation signal Technical field

The present invention relates to a mobile communication procedure in which a mobile station initiates a reception of downlink data, transmitted from a radio base station, using a downlink radio resource assigned persistently in the first cycles, at an initial start time of assignment, and transmits confirmation information for the downlink data using a persistently assigned uplink radio resource, and refers to the mobile station and the radio base station.

Prior art

The W-CDMA standardization organization, 3GPP, has considered a communication procedure as a successor to the W-CDMA scheme and the HSDPA scheme, specifically, the LTE scheme (long-term evolution), and work has begun of setting specifications.

As the radio access scheme of the LTE scheme, the use of OFDMA in the downlink and SC-FDMA (multiple frequency division access of a single carrier) in the uplink is being considered.

OFDMA is a scheme to divide a frequency band into several narrow frequency bands (subcarriers) and transmit data loaded into the respective divided frequency bands. In this scheme, high-speed transmission is achieved and the frequency use efficiency is improved by providing subcarriers densely in the frequency bands such that the subcarriers partially overlap but do not interfere with each other.

The SC-FDMA is a transmission scheme that reduces interference between terminals by dividing a frequency band and transmitting data using different frequency bands between several terminals. The SC-FDMA has a characteristic of less fluctuation in transmission power, which achieves low power consumption and wide terminal coverage.

The LTE scheme is a system in which several mobile stations perform communication by sharing one or more physical channels both uplink and downlink.

A channel shared by several mobile stations is generally referred to as a shared channel, which is, in the LTE scheme, a "physical uplink shared channel (PUSCH)" in the uplink and a "physical downlink shared channel. (PDSCH) ”on the downlink.

In addition, such a shared channel is, as a transport channel, an "uplink shared channel (UL-SCH)" on the uplink and a "downlink shared channel (DL-SCH)" on the downlink .

In such a communication system that uses shared channels as described above, it is necessary to select the mobile station, UE, to which the shared channel is to be assigned, and transmit, to the mobile station, UE, selected, a signal indicating the allocation of the shared channel, for each subframe (1 ms, in the LTE scheme).

In the LTE scheme, a control channel used for signaling is called "physical downlink control channel (PDCCH)" or "downlink L1 / L2 control channel (control channel L1 / L2 DL)".

Meanwhile, the processing for each subframe of selection of the mobile station, UE, to which the shared channel is to be assigned is generally referred to as "programming." In this case, the processing can also be referred to as "dynamic programming", because the mobile station, UE, to which the shared channel is to be assigned is dynamically selected for each subframe. In addition, the "shared channel assignment" described above may alternatively be expressed as "assignment of a radio resource for the shared channel".

The physical downlink control channel information includes, for example, the "downlink programming information", "the uplink programming concession", and the like.

The downlink programming information includes, for example, downlink resource block allocation information, UE ID, the number of flows, information on the prior coding vector, data size, modulation scheme, information on the HARQ (automatic repetition request

tnbrida), and the like, on the downlink shared channel.

Meanwhile, the "uplink programming concession" includes, for example, uplink resource block allocation information, UE ID, data size, modulation scheme, uplink transmission power information, information on the demodulation reference signal in the uplink MIMO, and the like, on the uplink shared channel.

Note that the "downlink programming information" and "uplink programming concession" described above can collectively be referred to as "downlink control information (DCI)".

In the LTE scheme, the HARQ is applied to a communication using the shared channel described above. For example, in the downlink, the mobile station, UE, decodes the downlink shared channel, and transmits, to the radio base station, eNB, confirmation information (ACK / nAcK) based on the decoding result (result CRC check) using the physical uplink control channel (PUCCH).

Then, the radio base station, eNB, performs the retransmission control according to a content of the confirmation information, which is expressed either with a positive response (ACK) indicating that the transmitted signal is properly received or either a negative response (NACK) that indicates that the transmitted signal is not received properly.

Figure 8 shows the dynamic downlink programming and HARQ processing in a mobile communication system of the LTE scheme described above.

In subframe # 3, the radio base station, eNB, transmits downlink programming information via a PDCCH to the mobile station, UE and downlink data via a PDSCH.

Then, the mobile station, UE, receives downlink data through the PDSCH, based on the downlink programming information received through the PDCCH.

In subframe # 7, the mobile station, UE, transmits the confirmation information for the downlink data using a PUCCH, and the radio base station, eNB, receives the confirmation information (ACK / NACK) mapped to the PUCCH.

The radio resource of the PDSCH described above is dynamically assigned as being notified by the PDCCH. In addition, the radio resource of the PUCCH described above is associated with the radio resource number of the PDCCH described above. The dynamic allocation of such radio resource of the PDCCH also results in the dynamic allocation of such radio resource of the PUCCH.

That is, in the normal downlink programming (dynamic programming) of a mobile communication system of the LTE scheme, the radio base station, eNB, is configured to dynamically allocate a downlink radio resource and a radio resource uplink to the mobile station, UE, through the PDCCH, being the downlink radio resource for transmitting downlink data to the mobile station, UE, being the uplink radio resource for transmitting confirmation information for Downlink data.

In addition, in the dynamic programming described above, a time difference is set between a subframe from which a PUCCH signal is transmitted and a subframe from which a PDCCH signal and a PDSCH signal are transmitted.

On the other hand, in the “persistent programming” that is being considered to achieve VoiP and the like, the radio base station, eNB, is configured to initiate a persistent assignment of the downlink radio resource (PDSCH) to a mobile station in the first cycles, in a subframe (first allocation start time) in which the downlink programming information is transmitted to the mobile station, UE, through the PDCCH, and to persistently allocate the radio resource of uplink (PUCCH) to the mobile station, UE, through the upper layer signaling (radio resource control: RRC).

In "persistent programming", the downlink programming information is transmitted by the PDCCH only in a first transmission, and the downlink programming information is not transmitted by the PDCCH in the subsequent transmissions. For this reason, the procedure for associating a radio resource of the PUCCH with a radio resource number of the PDCCH cannot be applied, unlike the "dynamic programming" described above.

Therefore, the uplink radio resource (PUCCH) in the "persistent programming" is persistently assigned to the mobile station, UE, using the upper layer signaling (RRC).

In this case, the uplink radio resource represents, for example, a code resource in the code multiplexing or a frequency resource in the frequency multiplexing.

The frequency resource may be designated by a resource block number of a resource block (set of subcarriers) from which the PUCCH is transmitted.

In addition, when a plurality of confirmation information is multiplexed within a resource block, the uplink radio resource may be designated by a predetermined identification number. For example, an identification number may be used to designate a quantity of cyclic displacement in the CAZAC sequence displacement multiplexing or an orthogonal cover code in the block propagation.

In addition, usually in the HARQ, a time difference is set between a time point at which the downlink radio resource (PDSCH) described above is assigned and a time point at which the resource is allocated. uplink radius (PUCCH) described above. Therefore, a transmission time of the PUCCH is uniquely determined by designating a first allocation start time through the PDCCH.

In the example shown in Figure 9, the downlink radio resource (PDSCH) described above is assigned persistently in 20 ms cycles, and the uplink radio resource (PUCCH) described above is assigned persistently for each downlink radio resource (PDSCH).

Specifically, the downlink radio resource (PDSCH) is persistently allocated in subframes # 3, # 23, ..., while confirmation information is transmitted in subframes # 7, No. 27,

Note that, in subframe # 3 of the example shown in Figure 9, a first assignment start time is designated by the PDCCH.

NTT DOCOMO ET AL, “UL ACK / NACK resource allocation for DL semi-persistent scheduling”, 3GPP DRAFT, R2- 082485, 3RD GENERATION PARTNERSHIP PROJECT (3GPP), MOBILE COMPETENCE CENTER, 650, ROUTE DES LUCIOLES, F-06921 SOPHIA- ANTIPOLIS CEDEX, FRANCE, vol. RAN WG2, No. Kansas City, USA, 20080429, April 29, 2008 (), XP050140169, [retrieved on] describes allocation of uplink ACK / NACK resources in persistent semi-programming. In particular, it is mentioned that only the frequency / code index and the temporal periodicity for semi-persistent ACK / NACK resources will be configured for RRC signaling. The starting point for semi-persistent ACK / NACK resources through the time at which the mobile station receives PDCCh for semi-persistent programming.

Summary of the invention

Problems that will be solved by the invention

In this case, in the prior art, a time difference between a time point at which the downlink radio resource (PDSCH) described above is assigned and a time point at which the radio resource is allocated from Uplink (PUCCH) described above, is specified as a predetermined period of time (for example, four subframes).

Therefore, when a time of the downlink radio resource (PDSCH) assigned in "persistent programming" is changed, a time in which the uplink radio resource (PUCCH) resource is also assigned is similarly changed.

Note that, in persistent programming, the uplink radio resource (PUCCH) such as a code resource in the code multiplexing and a frequency resource in the frequency multiplexing is persistently assigned to the mobile station, Ue , using the upper layer signaling as described above. For this reason, even in the case where a time is changed in which the uplink radio resource (PUCCH) is allocated, the uplink radio resource (PUCCH) such as the code resource is not changed. and the frequency resource.

At this time, if the uplink radio resource (PUCCH) assigned at a changed time is already used by another mobile station, UE, the uplink radio resource (PUCCH) after the change competes with the radio resource of Uplink (PUCCH) of the other mobile station, EU. Therefore, there has been a problem that the procedure of changing the time of the downlink radio resource (PDSCH) assigned in the "persistent programming" described above cannot be performed.

In other words, there has been a problem that a moment of the radio resource cannot be freely changed

downlink (PDSCH) assigned in "persistent programming", since a time difference is set between a time point at which the downlink radio resource (PDSCH) described above is assigned and a time point in which is assigned the uplink radio resource (PUCCH) described above, and the uplink radio resource (PUCCH) is set in advance.

Therefore, the present invention has been made to solve the above problems. An object of the present invention is to provide a mobile communication procedure, a mobile station and a radio base station that are capable of flexibly establishing a time of a downlink radio resource (PDSCH) assigned in "persistent programming" .

Ways of carrying out the invention

(Configuration of mobile communication system in accordance with the first embodiment of the present invention)

Referring to Figure 1 and Figure 2, a configuration of a mobile communication system according to a first embodiment of the present invention is described. This embodiment is described by mentioning a mobile communication system of the LTE scheme, but the present invention can also

apply to mobile communication systems to which any other scheme applies.

In a mobile communication system according to this embodiment, the mobile station, UE, is configured to initiate a reception of the downlink data transmitted from the radio base station, eNB, using a PDSCH (radio resource downlink) persistently assigned in first cycles, at a first start time of assignment, and to transmit confirmation information (ACK / NACK) for downlink data using a PUCCh (uplink radio resource).

In this case, a time difference is established between a moment of reception of the downlink data and a moment of transmission of the confirmation information.

As shown in Figure 1, the mobile station, UE, includes a persistent information receiving unit 11, a persistent assignment signal receiving unit 12, a downlink data receiving unit 13 and an ACK transmitter unit 14 / NACK.

The persistent information receiver unit 11 is configured to receive, from the radio base station, eNB, persistent information (persistent communication information) containing the first cycle and the first information described above on the uplink radio resource (PUCCH ).

Specifically, the persistent information receiving unit 11 is configured to acquire the persistent information described above based on an RRC message transmitted by the radio base station, eNB.

As will be described below, in the mobile communication system according to the first embodiment of the present invention, the information on the uplink radio resource (PUCCH) includes first information on the uplink radio resource (PUCCH) and second information on the uplink radio resource (PUCCH), and is notified from the radio base station, eNB, to the mobile station, UE.

As will be described below, the second information on the uplink radio resource (PUCCH) is notified by a persistent allocation signal, that is, a PDCCH indicating a persistent assignment of the PDSCH (downlink radio resource) for "persistent programming".

In this case, the information on the uplink radio resource (PUCCH) represents, for example, a resource block number of a resource block (set of subcarriers) to which the PUCCH is transmitted, or an identification number used when multiplying a plurality of confirmation information within a resource block.

For example, a quantity of cyclic displacement in the multiplexing of the CAZAC sequence cyclic displacement or an orthogonal cover number in the block propagation can be designated by such identification number.

In addition, a portion of information on the uplink radio resource (PUCCH) information is notified by persistent information (persistent communication information), while the rest of the information is notified by the persistent allocation signal such as It will be described below.

In this case, for example, the persistent information is an RRC message and the persistent assignment signal is the PDCCH indicating a persistent assignment of the PDSCH (downlink radio resource) for "persistent programming".

More precisely, for example, of the information on the uplink radio resource (PUCCH), a resource block number of a resource block (set of subcarriers) from which the PUCCH is transmitted can be notified by the persistent information (persistent communication information), while the rest of the information, specifically, an identification number used when multiplying a plurality of confirmation information within a resource block is notified by the persistent assignment signal as it is will describe below.

In this case, for example, the identification number is a quantity of cyclic displacement in the multiplexing of the CAZAC sequence cyclic displacement or an orthogonal cover number in the block propagation.

Note that the example described above is simply an example. The identification number used when multiplying a plurality of confirmation information within a resource block can be notified by persistent information (persistent communication information), while the rest of the information, namely, the resource block number of the Resource block (set of subcarriers) from which the PUCCH is transmitted can be notified by the persistent allocation signal.

Alternatively, a part of the information on the uplink radio resource (PUCCH) divided by any other procedure can be notified by persistent information (persistent communication information), while the rest of the information can be notified by the signal of persistent assignment.

Meanwhile, the information on the uplink radio resource (PUCCH) described above can be in any way provided that the radio resource can be identified.

For example, the information on the uplink radio resource (PUCCH) may be an identification number of a code resource in the code multiplexing described above, an identification number of a frequency resource in the frequency multiplexing, an identification number of a time resource in the time multiplexing, or an identification number of a resource in a hybrid multiplexing of the code multiplexing, the frequency multiplexing and the time multiplexing described above.

Also in this case, a part of the information on the uplink radio resource (PUCCH) is notified by persistent information (persistent communication information), while the rest of the information is notified by the persistent allocation signal.

More precisely, for example, when multiplexing is performed in accordance with a time multiplexing time multiplexing and frequency multiplexing, an identification number of a resource in the time multiplexing can be notified by persistent information (information on persistent communication), while an identification number of a resource in the frequency multiplexing can be notified by the persistent allocation signal, and vice versa.

Meanwhile, for example, when multiplexing is performed in accordance with a time multiplexing of the time multiplexing and the code multiplexing, an identification number of a resource in the time multiplexing can be notified by persistent information (persistent communication information ), while an identification number of a resource in the code multiplexing can be notified by the persistent assignment signal, and vice versa.

Meanwhile, for example, when multiplexing is performed in accordance with a frequency multiplexing of the frequency multiplexing and the code multiplexing, an identification number of a resource in the frequency multiplexing can be notified by persistent information (persistent communication information ), while an identification number of a resource in the code multiplexing can be notified by the persistent assignment signal, and vice versa.

The example described above shows a case in which a part of the information of the uplink radio resource information (PUCCH) is notified by persistent information (persistent communication information), while the rest of the information is notifies by persistent assignment signal. However, it is not always necessary to define the information to be notified by persistent information (persistent communication information) and the information to be notified by means of the persistent assignment signal so that they are exclusive to each other. This information may partially or totally overlap between st

Meanwhile, the information described above on the uplink radio resource (PUCCH) is supplied to the transmitting unit 14 of ACK / NACK.

In addition, in a mobile communication system of the LTE scheme, information is not included in the first allocation start time described above in such persistent information.

This is intended to cause the radio base station, eNB, to flexibly determine a time resource for allocating the PDSCH (downlink radio resource) described above, thereby improving the efficiency of use of the radio resource. when "persistent programming" is applied.

Meanwhile, it is not necessary that the time of transmission of the uplink radio resource (PUCCH) be contained as persistent information, since this information is determined uniquely based on the time of reception of the downlink radio resource (PDSCH) described above and a fixed time deviation.

For example, the transmission time of the uplink radio resource (PUCCH) can be defined as follows:

(Uplink radio resource transmission moment (PUCCH)) = (PDSCH downlink radio resource reception time)) + 4 ms

Meanwhile, the previous value of 4 ms is simply an example and therefore can be different from 4 ms. Alternatively, 4 ms can be expressed as four subframes.

The persistent assignment signal receiver unit 12 is configured to receive the persistent assignment signal from the radio base station, eNB.

Specifically, the persistent assignment signal receiver unit 12 is configured to receive, from the radio base station, eNB, a PDCCH indicating a persistent assignment of the PDSCH (downlink radio resource) for "persistent programming", such as persistent assignment signal.

For example, the persistent assignment signal receiver unit 12 may be configured to determine, based on RNTI or the like set for PDCCH, if the PDCCH is a PDCCH to indicate a persistent assignment of the PDSCH (downlink radio resource) for the "Persistent programming" or a PDCCH to dynamically allocate the PDSCH (downlink radio resource) for normal downlink programming.

Meanwhile, the persistent assignment signal receiver unit 12 may be configured to determine, based on a specific bit in the PDCCH, if the PDCCH is a PDCCH to indicate a persistent assignment of the PDSCH (downlink radio resource) for the "Persistent programming" or a PDCCH to dynamically allocate the PDSCH (downlink radio resource) for normal downlink programming.

Alternatively, when a portion of information elements in the PDCCH is configured to indicate whether the PDCCH is a PDCCH to indicate a persistent assignment of the PDSCH (downlink radio resource) for "persistent programming", or a PDCCH for dynamically assigning the PDSCH (downlink radio resource) for normal downlink programming, the persistent assignment signal receiving unit 12 may be configured to determine, based on the part of information elements in the previous PDCCH, if the PDCCH is a PDCCH to indicate a persistent assignment of the PDSCH (downlink radio resource) for "persistent programming", or a PDCCH to dynamically assign the PDSCH (downlink radio resource) for normal downlink programming.

In addition, the persistent assignment signal contains the second information on the uplink radio resource (PUCCH), in addition to the information to indicate a persistent assignment of the PDSCH (downlink radio resource) for "persistent programming".

In this case, the second information on the uplink radio resource (PUCCH) is, for example, a resource block number of the PUCCH (uplink radio resource), or information indicating an identification number used when a plurality of confirmation information is multiplexed within a resource block.

More precisely, as described above, the second information on the uplink radio resource (PUCCH) is information other than the information reported by persistent information (persistent communication information) (first radio resource information uplink (PUCCH)) of the information on the uplink radio resource (PUCCH).

In other words, a part of the information of the uplink radio resource information (PUCCH) is notified by persistent information (persistent communication information), while the rest of the information is notified by the assignment signal persistent.

In this case, for example, the persistent information is the RRC message, and the persistent assignment signal is the PDCCH indicating a persistent assignment of the PDSCH (downlink radio resource) for "persistent programming".

More precisely, for example, of the information on the uplink radio resource (PUCCH), the resource block number of the resource block (set of subcarriers) from which the PUCCH is transmitted can be notified by the information persistent (persistent communication information), while the rest of the information, specifically, the identification number used when multiplying a plurality of confirmation information within a resource block can be notified by the persistent allocation signal.

In this case, the identification number is, for example, the amount of cyclic displacement in the CAZAC sequence displacement multiplexing or the orthogonal cover number in the block propagation.

Note that the example described above is simply an example. From the information on the uplink radio resource (PUCCH), the identification number used when multiplying a plurality of

Confirmation information within a resource block can be notified by persistent information (persistent communication information), while the rest of the information, specifically, the resource block number of the resource block (subcarrier set) from which PUCCH is transmitted can be notified by persistent assignment signal.

Alternatively, a part of the information on the uplink radio resource (PUCCH) divided by any other procedure can be notified by persistent information (persistent communication information), while the rest of the information can be notified by the signal of persistent assignment.

Details of the second information on the uplink radio resource (PUCCH) will be described below.

Such second information on the uplink radio resource (PUCCH) is provided to the transmitting unit 14 of ACK / NACK.

The downlink data receiver unit 13 is configured to receive the downlink data transmitted by the PDSCH (downlink radio resource) allocated by the PDCCH.

Specifically, the downlink data receiving unit 13 is configured to, when receiving the persistent assignment signal (persistent assignment signal) described above by the persistent assignment signal receiving unit 12, determine a subframe that has received such a PDCCH as the first allocation start time described above, and initiate a persistent reception of the downlink data by means of the PDSCH (downlink radio resource) for the "persistent programming" in the first cycle described above, in the first time of start of assignment.

In the example shown in Figure 2, since the persistent assignment signal receiving unit 12 has received the persistent allocation signal described above in subframe # 3 by the PDCCH, the downlink data receiving unit 13 is configured to receive the downlink data via the PDSCH (downlink radio resource) mapped to resource blocks (resource block: subcarrier set) within subframe # 3 designated by the PDCCH.

In addition, the downlink data receiver unit 13 is configured to initiate a downlink data reception via a PDSCH (downlink radio resource) mapped to the resource blocks (resource block: subcarrier set) designated using the PDCCH in the 20 ms cycle, in subframe # 3.

That is, the downlink data receiver unit 13 is configured to receive the downlink data by means of the PDSCH (downlink radio resource) mapped to resource blocks (resource block: subcarrier set) designated by the PDCCH in subframes # 3, # 23, # 43, ....

The transmitting unit 14 of ACK / NACK is configured to receive, from the receiving unit 11 of persistent information, the first information on the uplink radio resource (PUCCH) notified by the persistent information.

In addition, the transmitting unit 14 of ACK / NACK is configured to receive, from the receiving unit 12 of persistent information, the second information about the uplink radio resource (PUCCH) notified by the persistent assignment signal.

The ACK / NACK transmitter unit 14 is configured to determine the uplink radio resource (PUCCH) based on the first information on the uplink radio resource (PUCCH) notified by persistent information and the second information on the resource uplink radio (PUCCH) notified by the persistent assignment signal, and to transmit confirmation information (ACK / NACK) corresponding to the downlink data received by the uplink radio resource (PUCCH). The confirmation information (ACK / NACK) is determined based on a decryption result of the downlink data by the downlink data receiver unit 13.

Using Figure 3, an example of a method of determining the uplink radio resource (PUCCH) based on the first information described above on the uplink radio resource (PUCCH) notified by persistent information and the second is shown. Information on the uplink radio resource (PUCCH) notified by the persistent assignment signal.

In Figure 3, two resource blocks are defined as uplink radio resource (PUCCH), and # 0 and # 1 are defined as resource block numbers thereof.

Meanwhile, eight radio resources are defined in each resource block, and # 0, # 1, # 2, ..., # 7 is defined as their identification numbers. For example, these identification numbers may be the identification numbers described above when a plurality of confirmation information is multiplexed within a resource block.

In this case, it is considered a case in which the resource block number No. 1 is designated by the first information on the uplink radio resource (PUCCH) notified by persistent information and the identification number is designated No. 5 by the second information on the uplink radio resource (PUCCH) notified by the persistent assignment signal.

In this case, the transmitting unit 14 of ACK / NACK determines the radio resource defined by the resource block number # 1 and the identification number # 5 within that resource block as a radio resource to transmit the confirmation information (ACK / NACK) corresponding to the downlink data received, that is, the uplink radio resource (PUCCH).

Specifically, the radio resource for transmitting the confirmation information (ACK / NACK) corresponding to the downlink data received, that is, the uplink radio resource (PUCCH), is determined based on the first information on the resource uplink radio (PUCCH) notified by persistent information and the second information on the uplink radio resource (PUCCH) notified by the persistent allocation signal.

In other words, part of the information about the uplink radio resource (PUCCH) is notified by persistent information, while the rest of the information is notified by the persistent assignment signal, and the link radio resource. Ascending (PUCCH) is determined based on both information.

In the example described above, the resource block number is notified by the first information described above on the uplink radio resource (PUCCH), while the identification information in a resource block is notified by the second information described. previously on the uplink radio resource (PUCCH). Instead, the identification information in a resource block can be notified by the first information described above on the uplink radio resource (PUCCH), while the resource block number can be notified by the second information described above. on the uplink radio resource (PUCCH).

Alternatively, a portion of the information on the uplink radio resource (PUCCH) divided by any other procedure may be reported as the first information on the uplink radio resource (PUCCH), while the rest of the information may be notified as a second information about the uplink radio resource (PUCCH).

In this case, the identification information in a resource block is, for example, the amount of dclic displacement in the CAZAC sequence displacement multiplexing or the orthogonal cover number in the block propagation.

Meanwhile, a plurality of identification numbers may be defined to identify resources other than those described above, and a portion of the plurality of identification numbers may be notified by the first information described above on the uplink radio resource (PUCCH), while the rest of the plurality of identification numbers can be notified by the second information described above on the uplink radio resource (PUCCH).

Although in the example described above eight radio resources are defined in each resource block, a similar procedure of determining the uplink radio resource (PUCCH) is applicable when more or less than eight radio resources are defined.

Meanwhile, although in the example described above two resource blocks are defined, it is also possible to define a single resource block or three or more resource blocks.

Meanwhile, in the example described above, the uplink radio resource (PUCCH) is determined based on the first information on the uplink radio resource (PUCCH) notified by persistent information and the second information on the resource. Uplink Radio (PUCCH) notified by persistent assignment signal. Instead, it is possible to apply a configuration in which the first information about the uplink radio resource (PUCCH) is not notified by persistent information and the second information about the uplink radio resource (PUCCH) is notifies using the PDCCH. In this configuration, the uplink radio resource (PUCCH) can only be determined by the second information on the uplink radio resource (PUCCH).

In this case, there is a disadvantage in that the number of bits for the information on the uplink radio resource (PUCCH) is increased, while there is an advantage in that the uplink radio resource (PUCCH) ) can be established more flexibly.

In the example described above, for example, the second information may be at least one of information such as a resource block number # 1 and information such as an identification number # 5.

Specifically, the identification number used when multiplying the plurality of confirmation information within a resource block or the resource block number of the PUCCH can be notified by the PDCCH.

By way of this, the second information on the uplink radio resource (PUCCH) is defined as a part of information elements to be notified by a persistent assignment signal (persistent assignment signal).

In this case, for example, when a signal format of the persistent assignment signal is the same as a signal format of the dynamic assignment signal in dynamic programming, the power control command bits used for the control of Transmission power in the dynamic allocation signal can be used as second information on the uplink radio resource (PUCCH).

In persistent programming, there is only little importance in the notification of the power control command used for transmission power control. Therefore, the bits of the command used for transmission power control can be used as second information on the uplink radio resource (PUCCH).

Alternatively, when the signal format of the persistent assignment signal is the same as the signal format of the dynamic assignment signal in dynamic programming, the bits that designate the "redundancy version" in the dynamic assignment signal They can be used as second information on the uplink radio resource (PUCCH).

In persistent programming, there is only little importance in the notification of the bits to designate the redundancy version. Therefore, the bits to designate the redundancy version can be used as second information on the uplink radio resource (PUCCH).

In this case, the redundancy version is set to a default redundancy version.

Alternatively, when the signal format of the persistent assignment signal is the same as the signal format of the dynamic assignment signal in dynamic programming, the bits that designate the “MCS (modulation and coding scheme)” in The dynamic assignment signal can be used as the second information on the uplink radio resource (PUCCH).

Since the number of bits to designate such MCS in persistent programming is smaller compared to dynamic programming, a part or all of such bits to designate the MCS can be used as second information on the uplink radio resource (PUCCH ).

Alternatively, when the signal format of the persistent assignment signal is the same as the signal format of the dynamic assignment signal in dynamic programming, a bit of a "new data indicator" in the dynamic assignment signal It can be used as a second information on the uplink radio resource (PUCCH).

Alternatively, when the signal format of the persistent allocation signal is the same as the signal format of the dynamic allocation signal in dynamic programming, a part or all of the bits to designate the "RB allocation" in The dynamic assignment signal can be used as the second information on the uplink radio resource (PUCCH).

Since the number of bits to designate such allocation of RB in persistent programming is smaller compared to dynamic programming, a part or all of such bits to designate the allocation of RB can be used as a second information on the radio resource of uplink (PUCCH).

Instead, when the signal format of the persistent assignment signal is the same as the signal format of the dynamic assignment signal in dynamic programming, at least any one of the power control command bit, the bit to designate the "redundancy version", the bits to designate the "MCS", the bits of the "new data indicator", and the bits to designate the "allocation of RB" can be used as second information on the radio resource of uplink (PUCCH).

In this case, since the resource can be designated based on a plurality of information elements in the PDCCH, it is possible to make a resource allocation of the PUCCH (uplink radio resource) in a more flexible manner.

If the first information about the uplink radio resource (PUCCH) is not notified by persistent information and only the second information about the uplink radio resource (PUCCH) is notified by the PDCCH, the control command bits of power, the bits to designate the "redundancy version", the bits to designate the "MCS", the bits of the "new data indicator", and the bits to designate the "allocation of RB" can be used as a signal to notify Information on the uplink radio resource (PUCCH).

In this case, the information on the uplink radio resource (PUCCH) is the identification number used when the plurality of confirmation information is multiplexed within a resource block or the PUCCH resource block number, for example .

As described above, the identification of whether the received PDCCH is the persistent assignment signal (persistent assignment signal) or the dynamic assignment signal is made based on RNTI or the like established in the PDCCH.

In other words, the mobile station, UE, considers the PDCCH as a dynamic allocation signal when the CRC in the RNTI of dynamic programming is “OK” (valid), and considers the PDCCH as a persistent allocation signal (persistent allocation signal) ) when the CRC in the RNTI of persistent programming is “OK”.

Then, when PDCCH is considered as a persistent assignment signal (persistent assignment signal), the mobile station, UE, receives a signal reception while considering that any of the bits of the power control command, the bits to designate the "Redundancy version", the bits to designate the "MCS", the "new data indicator" bits, and the bits to designate the "RB assignment" is used as the second information on the uplink radio resource ( PUCCH).

Note that a time at which confirmation information (ACK / NACK) is transmitted for the downlink data received by the uplink radio resource (PUCCH) is a uniquely determined time based on the time the resource is received. downlink radio (PDSCH) and fixed time deviation, as described above.

In addition, in the example described above, although the confirmation information (ACK / NACK) for the PDSCH (downlink data) is transmitted by the PUCCH, the confirmation information for the downlink data can be transmitted multiplexing with PUSCH when transmits a physical uplink shared channel to transmit uplink data in a subframe in which the confirmation information (ACK / NACK) is transmitted.

Alternatively, when the physical uplink shared channel for transmitting uplink data is assigned in the subframe in which the confirmation information (ACK / NACK) is transmitted, the confirmation information for such downlink data can be transmitted. as partial information within the PUSCH.

On the other hand, the radio base station, eNB, in accordance with the present invention is configured to notify, to the mobile station, UE, the first cycle and the information on the uplink radio resource (PUCCH).

The description of such information on the uplink radio resource (PUCCH) is omitted, as it is the same as the description provided for the mobile station, UE.

As shown in Fig. 4, the radio base station, eNB, includes a persistent information transmitter unit 21, a persistent assignment signal transmitter unit 22, a downlink data transmitter unit 23 and a receiver unit 24 from ACK / NACK.

The persistent information transmitter unit 21 is configured to transmit, to the mobile station, UE, the persistent information (persistent communication information) containing the first cycle and the first information on the uplink radio resource (PUCCH).

Specifically, the persistent information transmitter unit 21 is configured to notify the mobile station, UE, of the persistent information described above using an RRC message.

The description of the first information on the uplink radio resource (PUCCH) is omitted, as it is the same as the description provided for the mobile station, UE. Meanwhile, such first information on the uplink radio resource (PUCCH) is provided to the receiving unit 24 of ACK / NACK.

The persistent assignment signal transmitter unit 22 is configured to transmit, to the mobile station, UE, a persistent assignment signal.

Specifically, the persistent assignment signal transmitter unit 22 is configured to transmit, to the mobile station, UE, the PDCCH indicating a persistent assignment of the PDSCH (downlink radio resource) for "persistent programming", as a signal of persistent assignment.

Note that such a persistent assignment signal contains the information to indicate a persistent assignment of the PDSCH (downlink radio resource) for "persistent programming", and additionally contains second information about the uplink radio resource (PUCCH ) to notify the PUCCH resource block number (uplink radio resource) and the identification number used when multiplying a plurality of confirmation information within a resource block.

In this case, as described above, it is also possible to execute a processing in which the information on the uplink radio resource (PUCCH) is not notified by persistent information and the second information on the link radio resource. Ascending (PUCCH) is notified by the PDCCH.

The second information on the uplink radio resource (PUCCH) is supplied to the receiving unit 24 of ACK / NACK.

Note that the persistent allocation signal transmitter unit 22 may be configured to determine the content of the second information described above on the uplink radio resource (PUCCH) such that the radio resource of the confirmation information for the Downlink data does not compete with radio resources of the confirmation information transmitted from other mobile stations.

Using Figure 5, an example of a procedure for determining the content of the second information on the uplink radio resource (PUCCH) such that the radio resource of the confirmation information for the downlink data does not compete with the radio resources of the confirmation information transmitted from the other mobile stations.

In Figure 5, two resource blocks are defined as uplink radio resource (PUCCH), and # 0 and # 1 are defined as resource block numbers thereof. Meanwhile, eight radio resources are defined in each resource block, and # 0, # 1, # 2, ..., # 7 is defined as their identification numbers.

In this case, an assumption is made that the resource block number # 1 is notified by persistent information as the first information on the uplink radio resource (PUCCH).

Meanwhile, at a time of transmission of this confirmation information, the radio resources corresponding to the identification numbers No. 2, No. 3 and No. 4 in the resource block number No. 1 already They have been used by a mobile station, EU, No. A, a mobile station, EU, No. B and a mobile station, EU, No. C, respectively.

In this case, when the uplink radio resource (PUCCH) to be transmitted from the mobile station, UE, using the second information on the uplink radio resource (PUCCH) competes with the uplink radio resources (PUCCH) to be transmitted from the mobile stations, EU No. A, EU No. B and EU No. C, the transmission characteristics of the uplink radio resources (PUCCH) of the mobile stations, EU, competitors and the mobile station, EU, will be significantly deteriorated.

Accordingly, in order to avoid the competition described above, the persistent allocation signal transmitter unit 22 determines, for example, to establish the identification number of the uplink radio resource (PUCCH) of the mobile station, UE, to No. 5 by using the second information on the uplink radio resource (PUCCH). In this case, the determination to set the identification number to # 5 is simply an example and it is also possible to set the identification number to # 6 or # 1 provided there is no competition.

Alternatively, when processing is performed in which “the first information about the uplink radio resource (PUCCH) is not notified by persistent information and only the second information about the uplink radio resource is notified ( PUCCH) by means of the PDCCH ”as described above, the persistent allocation signal transmitter unit 22 may determine to notify the“ resource block number # 1 ”and the“ identification number No. 5 ”as information on the uplink radio resource in order to avoid the competition mentioned above.

In this case, it is also possible to notify, for example, the identification number No. 0 or No. 1 or the resource block No. 0 instead of the "Identification No. 5" as long as it does not occur competition.

The downlink data transmitter unit 23 is configured to transmit downlink data transmitted by the PDSCH (downlink radio resource) assigned by the PDCCH.

Specifically, the downlink data transmitter unit 23 is configured to, when the persistent assignment signal (persistent assignment signal) described above is transmitted by the persistent assignment signal transmitter unit 22, to determine a subframe in which it has been transmitted such PDCCH as the first allocation start time described above and initiate a transmission of the downlink data via the PDSCH (downlink radio resource) for "persistent programming" persistently in the first cycle described above, in the first start time of assignment.

The ACK / NACK receiving unit 24 is configured to receive, from the persistent information transmitter unit 21, the first information on the uplink radio resource (PUCCH) notified by the persistent information.

In addition, the ACK / NACK receiving unit 24 receives, from the persistent allocation signal transmitter unit 22, the second information on the uplink radio resource (PUCCH) notified by the persistent allocation signal.

The ACK / NACK receiving unit 24 is configured to determine the uplink radio resource (PUCCH) based on the first information on the uplink radio resource (PUCCH) notified by persistent information and the second information on the resource uplink radio (PUCCH) notified by persistent assignment signal, and to receive confirmation information (ACK / NACK) for downlink data transmitted by the uplink radio resource (PUCCH).

In this case, a procedure for determining the uplink radio resource (PUCCH) based on the first information on the uplink radio resource (PUCCH) notified by persistent information and the second information on the link radio resource Ascending (PUCCH) notified by the persistent assignment signal is the same as the description in the mobile station, UE, and will therefore be omitted.

(Operations of the mobile communication system in accordance with the first embodiment of the present invention)

Then, the mobile station, UE, acquires the first information on the uplink radio resource (PUCCH).

In step S102, the mobile station, UE, receives the persistent assignment signal (persistent assignment signal) transmitted from the radio base station, eNB, via the PDCCH. Then, the mobile station, UE, acquires the second information on the uplink radio resource (PUCCH) included in the persistent allocation signal.

In step S102, the mobile station, UE, determines a moment of reception of the persistent assignment signal as the first time of assignment start.

In step S103, the mobile station, UE, determines the uplink radio resource (PUCCH) based on the first information on the uplink radio resource (PUCCH) and the second information on the uplink radio resource (PUCCH).

In this case, for example, the first information on the uplink radio resource (PUCCH) may be the PUCCH resource block number, while the second information on the uplink radio resource (PUCCH) may be the orthogonal cover sequence number in the block propagation or the identification number that designates the amount of displacement in the CAZAC sequence.

Uplink radio (PUCCH) is similar to the procedure described above for determining the uplink radio resource (PUCCH) that has already been described in conjunction with the ACK / NACK transmitter unit 14 described above of the mobile station, UE.

In this case, when the processing is carried out in which “the first information on the uplink radio resource (PUCCH) is not notified by persistent information and only the second information on the uplink radio resource is notified ( PUCCH) by means of the PDCCH ”as described above, the uplink radio resource (PUCCH) is determined in step S103 based on the second information on the uplink radio resource (PUCCH) mapped on the PDCCH.

In step S104, the mobile station, UE, receives the downlink data via the PDSCH (downlink radio resource) for the "persistent programming" designated by the persistent assignment signal at a time of receiving the "programming persistent ”calculated from the first assignment start time and the first cycle.

In step S105, the mobile station, UE, transmits the confirmation information (ACK / NACK) for the downlink data received in step S104 via the uplink radio resource (PUCCH) determined in step S103.

Then, the mobile station, UE, receives downlink data via the PDSCH (downlink radio resource) assigned persistently in the first cycle (step S104), and transmits the confirmation information (ACK / NACK) for the downlink data via the PUCCH (uplink radio resource) (step S105).
