Description

FIELD OF THE INVENTION

The present invention relates to a mobile communication method in which a mobile station transmits uplink data with a predetermined period to a radio base station using the uplink radio resource allocated to this mobile station for long-term use, the transmission starting at the time the allocation starts. The present invention also relates to a mobile station and a radio base station.

State of the art

Standardization Organization W-CDMA (Wideband-Code Division Multiple Access), 3GPP, as a communication method that will replace the W-CDMA scheme and the HSDPA (High Speed Downlink Packet Access, high-speed packet downlink transmission) is considering LTE (Long Term Evolution), whose standards are still under development. In the LTE scheme, it is proposed to use the OFDMA (Orthogonal Frequency Division Division Multiple Access) scheme as the radio access method in the downlink, and the SC-FDMA (Single-Carrier Frequency Division Multiple Access) scheme is supposed to be used in the uplink frequency division multiple access and single carrier). In the OFDMA scheme, the frequency band is divided into many narrow frequency bands (subcarriers), and the data is transmitted on the corresponding subcarriers that are closely adjacent to the frequency band, partially overlapping, but not creating mutual interference, which allows to achieve high data rates with efficient use of the frequency spectrum . In the SC-FDMA scheme, by dividing the frequency band and using different frequency bands when transmitting by different terminals, mutual interference between the terminals is reduced. SC-FDMA is characterized by reduced fluctuations in transmit power, which reduces power consumption and increases the range of terminals.

In an LTE scheme, a plurality of mobile stations communicate with each other, sharing (dividing) one or more physical channels in both the uplink and the downlink. A channel shared by multiple mobile stations is commonly referred to as a shared channel. In the LTE system, the shared channels are the Physical Uplink Shared Channel (PUSCH) in the uplink and the Physical Downlink Shared Channel (PDSCH, Physical Downlink Shared Channel) in the downlink. In addition, such shared channels are, as transport channels, an uplink shared channel (UL-SCH) in an uplink, and a downlink shared channel (DL-SCH) in a downlink.

In a communication system using shared channels, for each subframe (1 ms in the LTE scheme), it is necessary to select a mobile station UE to which a shared channel will be allocated, and to report (signal) to the selected mobile station UE that a shared channel is allocated to this mobile station . In the LTE scheme, the control channel used for the indicated signaling is called the Physical Downlink Control Channel (PDCCH) or the L1 / L2 control channel (the L1 / L2 control channel of the downlink), and the mobile selection operation performed for each subframe the UE to which the shared channel will be allocated is usually called scheduling. This operation may also be called dynamic scheduling, since the mobile station UE to which the shared channel is allocated is selected dynamically for each subframe. In addition, instead of the expression “allocation of a shared channel” used above, the expression “allocation of radio resource for a shared channel” may be used.

The physical downlink control channel information includes, for example, downlink scheduling information, an uplink scheduling grant, and the like. Downlink scheduling information includes, for example, downlink shared channel allocation block allocation information, terminal UE-IDs, number of streams, precoding vector information, data size, modulation method, hybrid automatic re-request information transmissions (hybrid automatic repeat request, HARQ), etc. The uplink scheduling grant includes, for example, uplink shared channel allocation information on a downlink resource block, terminal UE-IDs, data size, demodulation method, uplink transmission power information, demodulation reference signal information MIMO uplink, etc. For the aforementioned downlink scheduling information and an uplink scheduling grant, the generic name “downlink control information (DCI)” may be used.

To determine whether an uplink scheduling grant or downlink scheduling information is addressed to a given mobile station, the indicated mobile station uses the UE-ID (RNTI) contained in the uplink scheduling grant or in the downlink scheduling information. More specifically, the CRC bits included in the uplink scheduling grant or in the downlink scheduling information are logically masked by the RNTI of the mobile station to which the uplink scheduling grant or downlink scheduling information is addressed. Using the CRC bits, the mobile station performs a CRC check, and if the result of the CRC check is success, then the mobile station considers that the uplink scheduling grant or downlink scheduling information is addressed to the mobile station, and if the result of the CRC check is unsuccessful, then the mobile the station considers that the uplink scheduling grant or downlink scheduling information is addressed to a given mobile station. Since CRC bits are used to determine the correctness or incorrectness of decoding the transmitted signal, for a mobile station that receives a signal in which the CRC bits are logically masked by the RNTI of another mobile station, the result of the CRC check will fail even if the specified signal was received correctly. The bit depth (number of bits) of the CRC and the bit width of the RNTI ID can be equal to, for example, 16. As a rule, in one subframe, the mobile station attempts to decode, for example, 40 uplink scheduling grants or 40 sending downlink scheduling information, the number of said uplink scheduling grants or sending downlink scheduling information can be, for example, a signal addressed to a given mobile station and a signal addressed to another mobile station, and a signal containing only noise without any useful signal, etc.

A known method of long-term planning (persistent scheduling), developed to implement VolP and similar technologies. Using this method, the radio base station eNB is configured to regularly allocate uplink or downlink (PUSCH or PDSCH) radio resource to a mobile station with a predetermined period starting from a subframe (allocation start time) indicated by the PDCCH (uplink scheduling grant communication or sending downlink scheduling information). Long-term planning may also be referred to as semi-persistent scheduling. The allocation start point mentioned here in the case of a downlink is a subframe in which downlink scheduling information is transmitted, and in the case of an uplink, it is an uplink subframe indicated by an uplink scheduling grant. The predetermined period is, for example, 20 ms. In long-term planning, the uplink scheduling grant or downlink scheduling information is transmitted via the PDCCH only for the first transmission act, while for subsequent transmission acts, neither the uplink scheduling grant nor the downlink scheduling information is transmitted via the PDCCH that reduces the need for radio frequency resources needed to transmit uplink scheduling grants or downlink scheduling information inii communication, that is, to reduce overhead and improve the efficiency of the communication system.

As indicated above, there are two types of uplink scheduling grant and downlink scheduling information: one type is for reporting resource allocation information to a mobile station using dynamic scheduling, the other type is for reporting resource allocation information to a mobile station on a long-term planning method . In this case, the allocation method used (dynamic planning or long-term planning) is determined based on the RNTI identifier or similar data, for example, based on the RNTI identifier specified in the uplink scheduling grant or in the downlink scheduling information. More specifically, for dynamic planning and for long-term planning, different RNTIs are set, and the allocation method used is determined based on the CRC check result of the corresponding RNTI.

The problem solved by the present invention

As mentioned above, a scheduling method (dynamic scheduling or long-term scheduling) reported to the mobile station by an uplink scheduling grant or downlink scheduling information is determined based on an RNTI or similar data specified in an uplink scheduling grant or scheduling information downlink, and in one subframe (in a time interval of 1 ms), the mobile station attempts to decode about 40 grants plan tion uplink or 40 parcels of information downlink scheduling. Since both the CRC and the RNTI have a bit depth of 16, the probability of a false positive is 1/2 ¹⁶ . Accordingly, when 40 grants of uplink scheduling or 40 sendings of downlink scheduling information are subject to decoding, the probability of false positive is 1/2 ¹⁶ × 40. False positive here refers to a situation in which a mobile station considers that an uplink scheduling grant or downlink scheduling information is addressed to a given mobile station, although the radio base station in this mobile station has neither an uplink scheduling grant nor downlink scheduling information communication did not transmit. When allocating a resource using the dynamic planning method, the negative impact of false positives is small, since the term for allocating a resource reported by an uplink planning grant or downlink planning information is limited by the duration of the corresponding subframe. However, when allocating a resource using the long-term planning method, false positives have a significant negative impact, because after the uplink planning grant or the downlink planning information indicates the moment of allocation, the long-term radio resource allocation is carried out. As a result, for example, the mobile station can transmit in the uplink, although the radio base station has not allocated any radio resources for this. The uplink signal transmitted in such a situation is an obstacle for other mobile stations, which leads to a significant decrease in the quality indicators of the mobile communication system. The problem of false positives can also occur when, instead of RNTI, a specific bit is used in the PDCCH to indicate the scheduling method, the value of which corresponds to either regular allocation of PDSCH (radio resource downlink) for long-term planning or dynamic allocation of PDSCH (radio resource downlink) during normal planning .

The implementation of the invention

The design of a mobile communication system in accordance with the first embodiment of the present invention

Next, with reference to FIG. 1, a construction of a mobile communication system in accordance with a first embodiment of the present invention is described. In this embodiment, the description is given as an example of a mobile communication system using an LTE scheme, but the present invention is also applicable to mobile communication systems using other schemes.

In the mobile communication system in accordance with this embodiment, the mobile station UE is configured to transmit uplink data to a radio base station eNB with a predetermined period using the PUSCH (uplink radio resource) for long-term use, and transmission starts at the time of allocation. More specifically, in the mobile communication system in accordance with this embodiment, the mobile station UE is configured to transmit uplink data to the radio base station using the uplink radio resource by predetermined scheduling information of the designated mobile station for long-term use with a predetermined period.

As shown in FIG. 1, the mobile station UE includes a long-term communication parameter information receiving section 11, a long-term allocation signal receiving section 12, and an uplink data transmission section 13.

The long-term communication parameter information receiving module 11 is configured to receive long-term planning information from a radio base station eNB containing a predetermined period and uplink radio resource information. In addition, the module 11 for receiving information about the parameters of long-term communication is configured to report the specified information about the radio resource of the uplink communication module 12 for receiving a signal of long-term allocation. Specifically, the long-term communication parameter information receiving unit 11 is configured to extract long-term scheduling information from an RRC message transmitted by the radio base station eNB. The uplink radio resource information here is, for example, the information discussed below, which serves to limit the range of information to be reported by a long-term allocation signal (i.e., via predetermined scheduling information), i.e., a PDCCH (uplink scheduling grant ) containing the command for the long-term allocation of the channel PUSCH (uplink radio resource) for long-term planning. Details are explained in the following description.

The information elements of the PDCCH (uplink scheduling grant) reporting long term allocation may be information elements, shown as an example in FIG. 2.

The Format Indicator indicates the communication line to which the PDCCH information refers (uplink or downlink). Information for the downlink is also called simplified downlink control information.

The Hopping flag indicates whether or not hopping is applied to the upstream signal, the transmission of which is requested by the PDCCH.

RB assignment information is resource allocation information for an uplink signal, the transmission of which is requested by the PDCCH.

The modulation and coding scheme information (MCS information) is the modulation and coding scheme information for the uplink signal, the transmission of which is requested by the PDCCH. The information about the modulation and coding scheme here is, for example, information such as data size, modulation scheme, and the Redundancy Version in HARQ.

The New Data Indicator is information about the type of transmission of the upstream signal, the transmission of which is requested by the PDCCH (new transmission or retransmission).

Transmission power control (TPC) information is information for controlling the transmission power of an uplink signal indicated by a PDCCH.

The cyclic shift for the demodulation reference signal (Cyclic shift for DMRS) is information about the cyclic shift of the demodulation reference signal for the uplink signal indicated by the PDCCH.

A CQI request is an uplink CQI request.

RNTI / CRC are CRC bits logically masked by a UE-ID (RNTI).

It should be noted that the above information items of the PDCCH (uplink scheduling grant) are merely examples, and other information elements may be included in the PDCCH, just as some of the above information elements may not be included in the PDCCH.

The uplink radio resource information may be information for limiting a range of information values to be reported by the aforementioned PDCCH (uplink scheduling grant) in accordance with the following description. For example, the uplink radio resource information may be information serving to limit the range of information to be reported by the aforementioned resource block allocation information. More specifically, the uplink radio resource information may be information serving to impose a limit on the number of resource blocks to be reported by the above resource block allocation information. In particular, the uplink radio resource information may be information serving to limit the number of resource blocks to be reported by the aforementioned resource block allocation information to 2 and 3. If the number of resource blocks reported by the PDCCH (uplink scheduling grant communication line), neither 2 nor 3 is equal, then the information about the uplink radio resource and the information (information about the allocation of the resource block) reported via the PDCCH (grant grant uplink Ia) do not match.

Alternatively, the uplink radio resource information may be information serving to indicate the largest number of resource blocks to be reported by the above resource block allocation information. For example, the uplink radio resource information may be information serving to limit the number of resource blocks to be reported by the above resource block allocation information to values less than or equal to 3. If the number of resource blocks reported by the PDCCH (scheduling grant uplink) exceeds 3, then the uplink radio resource information and information (resource block allocation information) reported via the PDCCH (grant uplink planning) do not match.

It will be appreciated that the uplink radio resource information, instead of the above example of indicating the largest value of the number of resource blocks reported by the above resource block allocation information, may indicate the smallest value of the number of resource blocks. Alternatively, the uplink radio resource information may indicate both the largest and smallest values of the number of resource blocks to be reported by the above resource block allocation information. For example, the uplink radio resource information may indicate 10 as the largest value of the number of resource blocks to be notified by the above resource block allocation information, and may indicate 5. If the number of resource blocks reported by channel PDCCH (uplink scheduling grant), more than 10 or less than 5, then the information about the radio resource of the uplink communication and information (information about the allocation of the block ESOURCES) communicated through channel PDCCH (uplink grant scheduling) do not correspond to each other.

When using the uplink radio resource information to impose a limit on a range of information values to be reported by the above resource block allocation information, the method of said restriction may include not only the above-described restriction of the number of resource blocks. The uplink radio resource information may also impose a limit on the range of values of other information to be reported through resource block allocation information. For example, the uplink radio resource information may be information imposing a restriction on the position of the resource block on the frequency axis, reported by the aforementioned resource block allocation information. Alternatively, the uplink radio resource information may be information imposing a restriction on the information to be reported by the above modulation and coding scheme information, for example, information limiting a range of values of parameters such as a modulation scheme, data size, and the like. In particular, the uplink radio resource information may be information imposing a restriction on the modulation scheme to be reported by the modulation and coding scheme information, and more specifically, information limiting the modulation scheme options that can be communicated by the modulation scheme information and coding, only QPSK scheme. If the modulation scheme reported by the PDCCH (uplink scheduling grant) differs from QPSK (for example, it is a 16QAM modulation scheme), then the uplink radio resource information and information (modulation and coding scheme information) reported by the channel PDCCH (uplink scheduling grant) do not match.

It should be noted that information on the uplink radio resource, instead of the illustrated above example of limiting the allowed modulation scheme variants to be reported by the modulation and coding scheme information, to the QPSK only, can limit the allowed modulation scheme information to be reported by the modulation scheme information and encoding, only 16QAM, only 64QAM, or QPSK and 16QAM. More specifically, the uplink radio resource information may indicate whether the QPSK, 16QAM, and 64QAM are each of the allowed variations of the modulation scheme to be reported by the modulation and coding scheme information.

Alternatively, the uplink radio resource information may be information imposing a limitation, for example, on the size of the data to be reported by modulation and coding scheme information. For example, the uplink radio resource information may be information limiting the size of the data to be reported by modulation and coding scheme information to 320 bits. If the data size reported via the PDCCH (uplink scheduling grant) is different from 320 bits (for example, 512 bits), then the uplink radio resource information and information (modulation and coding scheme information) reported by channel PDCCH (uplink scheduling grant), do not match. It is understood that the value 320 used here for the number of bits is just an example, and instead of it, the number of bits other than 320 can be set. In addition, although only one data size value is specified in the above example, two or more data size values are allowed . For example, the uplink radio resource information may be information to limit the size of the data to be reported by modulation and coding scheme information, for example, 320 bits and 640 bits.

Alternatively, the uplink radio resource information may be information imposing a restriction on the size of the data to be reported by modulation and coding scheme information, for example, values not exceeding 320 bits. If the data size reported via the PDCCH (uplink scheduling grant) is more than 320 bits (for example, 512 bits), then the uplink radio resource information and information (modulation and coding scheme information) reported through the channel PDCCH (uplink scheduling grant) do not match. It is understood that the value 320 used here for the number of bits is just an example, and instead of it, the number of bits other than 320 can be set. In addition, although the data size is set to the largest value in the above example, the smallest data size value can be set instead. or, alternatively, the largest and smallest data size values can be specified. For example, 640 bits can be set as the largest data size value, and 320 bits can be set as the smallest data size value. If the data size reported through the PDCCH (uplink scheduling grant) is more than 640 bits or less than 320 bits, then the uplink radio resource information and information (modulation and coding scheme information) reported through the PDCCH (grant uplink planning) do not match.

It should be noted that the information about the uplink radio resource instead of the illustrated by the above example, imposing a restriction on the information communicated by the information on the allocation of the resource block or on the information communicated by the information on the modulation and coding scheme, can in the same way impose a restriction on any element information other than the above. In addition, the above resource block allocation information and modulation and coding scheme information are information related to resource blocks or information related to the modulation scheme or data size, therefore, resource block allocation information and modulation and coding scheme information may be referred to as transmission format information.

The long-term allocation signal receiving unit 12 is configured to receive the long-term allocation signal from the radio base station eNB. Specifically, the long-term allocation signal receiving unit 12 is configured to receive, from the radio base station eNB, as a long-term allocation signal of the PDCCH (uplink scheduling grant) addressed to this mobile station and containing a command for the long-term allocation of the PUSCH (uplink radio resource) for long-term planning. For example, the long-term assignment signal receiving unit 12 may be configured to verify, based on the RNTI and similar parameters specified in the PDCCH, whether the PDCCH (uplink scheduling grant) containing the PUSCH long-term allocation command is addressed to the mobile station (uplink radio resource) for long-term planning. Instead, the long-term allocation signal receiving unit 12 may be configured to check, based on the RNTI and similar parameters specified in the PDCCH, whether the received PDCCH is intended to dynamically allocate the PUSCH (uplink radio resource), i.e. whether this PDCCH is an uplink scheduling grant for dynamic scheduling.

In the case where to implement long-term planning in the LTE scheme, an indication of whether the PDCCH (uplink scheduling grant) reports on the long-term allocation of the PUSCH (uplink radio resource) for long-term planning or on the dynamic allocation of the PUSCH (uplink radio resource) ) for dynamic scheduling, performed by one specific bit in the PDCCH, then the long-term allocation signal receiving module 12 may be configured to determine whether the PDCCH is reporting anirovaniya uplink) allocation of the long channel PUSCH (uplink radio resource) for the long-term plan or dynamic channel allocation on the PUSCH (uplink radio resources) for dynamic scheduling, based on one of said bit.

Alternatively, if to implement long-term scheduling in the LTE scheme, an indication of whether the PDCCH (uplink scheduling grant) reports on the long-term allocation of the PUSCH (uplink radio resource) for long-term scheduling or on the dynamic allocation of the PUSCH (uplink radio resource) ) for dynamic scheduling, carried out by a part of the PDCCH information elements, the long-term allocation signal receiving unit 12 may be configured to determine whether the PDCCH is reporting ( welt uplink scheduling) on long-term allocation of channel PUSCH (uplink radio resource) for the long term planning or dynamically allocated channel PUSCH (uplink radio resources) for dynamic scheduling, on the basis of said part elements PDCCH information.

In addition, the long-term allocation signal receiving unit 12 is configured to receive uplink radio resource information from the long-term planning information receiving unit 11. The uplink radio resource information here, as mentioned above, is information serving to impose a limit on the range of values of the information to be reported by the long term allocation signal, i.e. a PDCCH (uplink scheduling grant) containing a command for long-term allocation of a PUSCH (uplink radio resource) for long-term scheduling.

In addition, the long-term allocation signal receiving unit 12 checks whether the uplink radio resource information and the information to be reported by the long-term allocation signal, i.e. channel PDCCH (uplink scheduling grant) containing a command for the long-term allocation of the channel PUSCH (radio resource uplink communication) for long-term planning. If the long-term allocation signal receiving unit 12 recognizes the uplink radio resource information and information to be reported by the long-term allocation signal, i.e. channel PDCCH (uplink scheduling grant) containing a command for long-term allocation of the PUSCH (radio resource uplink) for long-term planning, not consistent with each other, then the module 12 receiving the long-term allocation signal refuses to use the long-term allocation signal, i.e. a PDCCH (uplink scheduling grant) containing a command for long-term allocation of a PUSCH (uplink radio resource) channel for long-term scheduling, which the long-term allocation signal receiving unit 12 has been addressed to this mobile station.

Specifically, in this case, the long-term allocation signal receiving unit 12 considers the information reported by the long-term allocation signal, i.e. a PDCCH (uplink scheduling grant) containing a command for long-term allocation of a PUSCH (uplink radio resource) for long-term scheduling addressed to a non-given mobile station. In the above operation, the long-term allocation signal receiving unit 12 transmits a long-term allocation signal, i.e. a PDCCH (uplink scheduling grant) containing a command for long-term allocation of a PUSCH (uplink radio resource) for long-term scheduling in which no waiver has been performed to the uplink data transmitting unit 13.

The following is an example of the above operation, including the rejection of the use of the long-term allocation signal, i.e. a PDCCH (uplink scheduling grant) containing a command for long-term allocation of a PUSCH (uplink radio resource) for long-term scheduling.

If the uplink radio resource information is information limiting the number of resource blocks to be reported by the resource block allocation information to, for example, 2 or 3, and the number of resource blocks reported by the PDCCH (uplink scheduling grant) is not is neither 2 nor 3, then the long-term allocation signal receiving unit 12 recognizes the uplink radio resource information and the information (resource block allocation information) reported via the channel and the PDCCH (uplink scheduling grant) is not consistent with each other and refuses to use the information of the PDCCH (uplink scheduling grant).

Alternatively, if the uplink radio resource information is information limiting the number of resource blocks to be reported by the resource block allocation information, for example, 3 or less, and the number of resource blocks reported by the PDCCH (uplink scheduling grant) greater than 3 (for example, equal to 5), then the long-term allocation signal receiving module 12 recognizes the uplink radio resource information and information (information about the allocation of the resource block), schennuyu through channel PDCCH (uplink grant scheduling) not corresponding to each other, and performs the rejection of the use of information of the channel PDCCH (uplink grant scheduling).

Alternatively, if the uplink radio resource information is information limiting the number of resource blocks to be reported by the resource block allocation information, for example, from 5 to 10 inclusive, and the number of resource blocks reported by the PDCCH (uplink scheduling grant communication), greater than 10 or less than 5 (for example, equal to 12), then the long-term allocation signal receiving module 12 recognizes the uplink radio resource information and information (allocation information resource block) reported by the PDCCH (uplink scheduling grant) is not consistent with each other and refuses to use the information of this PDCCH (uplink scheduling grant).

Alternatively, if the uplink radio resource information is information restricting the modulation scheme to be reported by the modulation and coding scheme information, for example, only to the QPSK scheme, and the modulation scheme reported by the PDCCH (uplink scheduling grant) is not is a QPSK scheme (and is, for example, a 16QAM scheme), then the long-term allocation signal receiving unit 12 recognizes uplink radio resource information and information (modulation scheme information and coding ) reported by the PDCCH (uplink scheduling grant) are not consistent with each other and rejects the use of the information of this PDCCH (uplink scheduling grant).

Alternatively, if the uplink radio resource information is information limiting the size of the data to be reported by the modulation and coding scheme information to, for example, 320 bits, and the data size reported through the PDCCH (uplink scheduling grant) is not equal to 320 bits (and is, for example, 1024 bits), then the long-term allocation signal receiving module 12 recognizes the uplink radio resource information and information (information about the modulation and coding scheme), summarized by the channel PDCCH (uplink scheduling grant), are not consistent with each other and rejects the use of the information of this channel PDCCH (uplink scheduling grant).

Alternatively, if the uplink radio resource information is information limiting the size of the data to be reported by the modulation and coding scheme information to, for example, 320 bits or less, and the data size reported through the PDCCH (uplink scheduling grant ), more than 320 bits (and is, for example, 512 bits), then the long-term allocation signal receiving module 12 recognizes the uplink radio resource information and information (modulation scheme information and coding ) reported by the PDCCH (uplink scheduling grant) are not consistent with each other and rejects the use of the information of this PDCCH (uplink scheduling grant).

Alternatively, if the uplink radio resource information is information limiting the size of the data to be reported by modulation and coding scheme information, for example, a value in the range from 320 bits to 640 bits inclusive, and the data size reported through the PDCCH (grant scheduling of the uplink), more than 640 bits or less than 320 bits (for example, 1024 bits), the module 12 receiving the long-term allocation signal recognizes information about the radio resource of the uplink deformations of (information about a modulation and coding scheme), communications through channel PDCCH (uplink grant scheduling) not corresponding to each other, and performs the rejection of the use of information of the channel PDCCH (uplink grant scheduling).

In the above example, the long-term allocation signal receiving unit 12 checks whether the uplink radio resource information and the information to be communicated by the long-term allocation signal correspond to each other, i.e. channel PDCCH (uplink scheduling grant), reporting the long-term allocation of the channel PUSCH (radio resource uplink communication) for long-term planning, but instead, the module 12 receiving the long-term allocation signal may check for inconsistencies other than those above, and if such non-conformities, the long-term allocation signal receiving unit 12 may refuse to use the long-term allocation signal, i.e. a PDCCH (uplink scheduling grant) containing a command for long-term allocation of a PUSCH (uplink radio resource) for long-term scheduling. For example, if the mobile station does not have the ability to transmit in the uplink using the 64QAM scheme, and the module 12 receiving the long-term allocation signal by the long-term allocation signal, i.e. channel PDCCH (uplink scheduling grant), containing the command for the long-term allocation of the channel PUSCH (radio resource uplink communication) for long-term planning, received a request to transmit using the 64QAM scheme, the module 12 receiving the long-term allocation signal may refuse to use this long-term signal discharge, i.e. a PDCCH (uplink scheduling grant) containing a command for long-term allocation of a PUSCH (uplink radio resource) for long-term scheduling.

Another example is the situation in which the largest data that the mobile station can transmit is 10,000 bits, and the module 12 receiving the long-term allocation signal by means of the long-term allocation signal, i.e. channel PDCCH (uplink scheduling grant), containing the command for the long-term allocation of the channel PUSCH (radio resource uplink communication) for long-term planning, received a request to transmit an upward signal with a data size of 20,000 bits, the module 12 receiving a signal of long-term allocation may refuse to use the signal long-term discharge, i.e. a PDCCH (uplink scheduling grant) containing a command for long-term allocation of a PUSCH (uplink radio resource) for long-term scheduling.

A situation is not excluded in which in the signal of long-term allocation, i.e. the PDCCH (in the uplink scheduling grant) containing the command for the long-term allocation of the PUSCH (uplink radio resource) for long-term scheduling contains a bit configuration that does not indicate the information to be reported by the indicated signal. Accordingly, when the configuration of the bits of the long-term allocation signal, i.e. channel PDCCH (uplink scheduling grant), containing the command for the long-term allocation of the channel PUSCH (radio resource uplink communication) for long-term planning, does not mean information to be reported by the specified signal, the module 12 receiving the long-term allocation signal may refuse to use the long-term allocation signal, those. a PDCCH (uplink scheduling grant) containing a command for long-term allocation of a PUSCH (uplink radio resource) for long-term scheduling. In this case, the expression “bit configuration not meaning the information to be reported by the indicated signal” may in other words be formulated as “bit configuration not to be reported”. In this case, the long-term allocation signal receiving unit 12 may, regardless of the uplink radio resource information, determine whether some configuration of the bits of the long-term allocation signal, i.e. channel PDCCH (uplink scheduling grant) containing a command for long-term allocation of the channel PUSCH (radio resource uplink) for long-term planning, the value of the above information. Alternatively, the long-term allocation signal receiving unit 12 may determine whether some bit configuration of the long-term allocation signal has, i.e. channel PDCCH (uplink scheduling grant), containing a command for the long-term allocation of the channel PUSCH (radio resource uplink communication) for long-term planning, the value of the above information, in the absence of information about the radio resource uplink communication.

The following are examples of the aforementioned bit configuration, which was not intended to be reported.

If, for example, it is specified that the number of resource blocks indicated in the long-term allocation signal by the resource block allocation information shown in FIG. 2 never exceeds 10, then the bit configuration representing the number of resource blocks in the resource block allocation information and corresponding a value greater than 10 is recognized as a bit configuration that was not intended to be reported. Specifically, the mobile station UE refuses to use the long-term allocation signal if the number of resource blocks indicated by the resource block allocation information in the long-term allocation signal is greater than 10.

Alternatively, if, for example, it is specified that the data size indicated in the signal of long-term allocation of information about the modulation and coding scheme shown in FIG. 2 never exceeds 1000, then the bit configuration representing the size of the data in the information about the modulation and coding scheme and corresponding to a value greater than 1000 is recognized as a bit configuration that was not intended to be reported. Specifically, the mobile station UE refuses to use the long-term allocation signal if the data size value indicated by the modulation and coding scheme information in this long-term allocation signal exceeds 1000.

It should be noted that the expression “if the data size value indicated by the modulation and coding scheme information is greater than 1000” may mean, for example, that a part of the bits of the specified modulation and coding scheme information does not represent a certain value set in advance.

If the data size is specified by a four-digit binary number written as "abcd" (where the first character " a " corresponds to the most significant bit), then in the form of a decimal number, the data size is expressed as (data size expressed as a decimal number) = 2 ³ × a +2 ² × b + 2 ¹ × c + 2 ⁰ × d.

If the bit a , which is the most significant bit, is not 0, i.e. if a = 1, then the data size is at least 8. Specifically, the mobile station UE may refuse to use the long-term allocation signal if some of the modulation and coding scheme information bits in this long-term allocation signal do not represent a certain value set in advance. In particular, the mobile station UE may refuse to use the long-term allocation signal if the most significant bit of the modulation and coding scheme information in this long-term allocation signal does not represent a certain value set in advance (if, for example, as in the above example, the most significant bit is not equal to 0), or if a predetermined number of successive bits, starting with the most significant bit does not constitute a value set in advance (for example, if a bit audio, audio is not equal to the bit b s 0 on the assumption that in the above example to indicate the aforementioned certain value specified in advance, using two consecutive bits). The same technology can be used if the information on the modulation and coding scheme indicates both the data size and the modulation scheme.

Alternatively, if, for example, it is specified that the modulation scheme indicated in the signal of long-term allocation of information about the modulation and coding scheme shown in FIG. 2 is always a QPSK scheme, then the bit configuration representing the modulation scheme in the information about the modulation and coding scheme and corresponding to a 16QAM or 64QAM scheme, is recognized as a bit configuration that was not intended to be reported. Specifically, the mobile station UE refuses to use the long-term allocation signal if the modulation scheme indicated by the modulation and coding scheme information in this long-term allocation signal is not a QPSK scheme.

Alternatively, if, for example, the bit configuration in the information about the modulation and coding scheme indicates the modulation scheme used in the retransmission, then this bit configuration is recognized as a bit configuration, which was not supposed to be reported, since the long-term allocation signal is inherently a signal that needs to be started new gear. Specifically, if the modulation and coding scheme information in the long-term allocation signal reports a bit configuration indicating the modulation scheme used in the retransmission, then the mobile station UE refuses to use the long-term allocation signal.

Alternatively, if, for example, it is specified that the value of the transmission power control information shown in FIG. 2 is always 1 in the long-term allocation signal, then 0 as the value of the transmission power control information is recognized as a bit configuration, which was not intended to be reported. Specifically, the mobile station UE refuses to use the long-term allocation signal if the transmission power control information value in this long-term allocation signal is 0. Although in the above example, the number of bits of the transmission power control information is 1, the indicated number of bits may differ from 1 and be equal to, for example, 2 or 3. For example, if the number of bits of the transmission power control information is 2, and it is specified that the value of the transmission power control information is always 11, the configuration bits 10, 01 and 00 are considered configuration bits that are not supposed to communicate.

Alternatively, if, for example, it is specified that the cyclic shift value for the demodulation reference signal shown in FIG. 2 is always 1 in the long-term allocation signal, then 0 is recognized as a bit configuration for the cyclic shift value for the demodulation reference signal, which is not reported was supposed. Specifically, the mobile station UE refuses to use the long term allocation signal if the cyclic shift value for the demodulation reference signal in this long term allocation signal is 0. Although in the above example, the number of bits in the cyclic shift for the demodulation reference signal is 1, the number of bits may differ from 1 and be equal, for example, 2 or 3.

Alternatively, if, for example, it is specified that the CQI request value shown in FIG. 2 is always 1 in the long-term allocation signal, then 0 as the CQI request value is recognized by the bit configuration, which was not intended to be reported. Specifically, the mobile station UE refuses to use the long-term allocation signal if the CQI request value in this long-term allocation signal is 0.

Alternatively, if, for example, it is specified that the value of the new data indicator shown in FIG. 2 is always 1 in the long-term allocation signal, then 0 as the value of the new data indicator is recognized by the bit configuration, which was not supposed to be reported. Specifically, the mobile station UE refuses to use the long-term allocation signal if the value of the new data indicator in this long-term allocation signal is 0.

Alternatively, the mobile station UE may determine that some bit configuration is a bit configuration not to be reported based on information contained in a previously received long-term allocation signal. For example, if the data size indicated by the modulation and coding scheme information in the previously received long-term allocation signal was always 320 bits, then the mobile station UE may consider the bit configuration indicating a data size other than 320 bits as a bit configuration not to be reported . Earlier, as an example, it was assumed that a false positive occurs in the mobile station UE, which has never before received the correct long-term allocation signal. In the case where the mobile station UE has received at least three times a long-term allocation signal having the same data size, the mobile station UE may consider the bit configuration with a data size different from the above data size, the bit configuration, which was not supposed to be reported. Alternatively, the mobile station UE may consider the bit configuration with a data size different from the aforementioned data size, a bit configuration that was not expected to be reported if the mobile station UE had received at least three consecutive times a long-term allocation signal having the same data size. It should be noted that the numerical values used in the above example are 320 bits and three times are only examples, and these numerical values may be different.

The above operations for not using a PDCCH (uplink scheduling grant) containing a command for long-term allocation of a PUSCH (uplink radio resource) for long-term scheduling can be performed simultaneously. Specifically, if when performing several operations to refuse to use the PDCCH channel containing the command to use long-term scheduling, at least one of these operations will establish the need to refuse to use the PDCCH channel, then the use of the PDCCH channel containing the command about using long-term planning.

The uplink data transmission unit 13 is configured to transmit uplink data to be transmitted via the PUSCH (uplink radio resource) allocated by the PDCCH.

Specifically, the uplink data transmission unit 13 is configured to determine, as the aforementioned start time of the allocation, the uplink transmission subframe if the above-described long-term allocation signal is received from the long-term allocation signal receiving unit 12, i.e. a PDCCH (uplink scheduling grant) containing a command for long-term allocation of a PUSCH (uplink radio resource) channel for long-term scheduling and indicating the named transmission subframe on the uplink, and then, with the possibility of starting at the named time, the start of allocation of long-term uplink transmission data via the PUSCH (uplink radio resource) for long-term scheduling, with the aforementioned predetermined period. In the example of FIG. 3, after receiving the long term allocation signal by the long term allocation signal receiving unit 12 in the subframe # 3 via the PDCCH, the uplink data transmission unit 13 transmits in the uplink with a period of 20 ms starting from the transmission subframe # 7 indicated PDCCH data, uplink data through a PUSCH channel (uplink radio resource) mapped to a resource block (a set of subcarriers). In other words, the uplink data transmission unit 13 is configured to transmit uplink data via a PUSCH (uplink radio resource) mapped to a resource block (a plurality of subcarriers) indicated by the PDCCH in subframes # 7, # 27, # 47, ....

A radio base station eNB in accordance with the present invention is configured to report a predetermined period and uplink radio resource information to the mobile station UE. Since the description related to the uplink radio resource information is the same as the above description for the mobile station UE, this description is not given here.

As shown in FIG. 4, the radio base station eNB includes a long-term parameter information transmitting unit 21, a long-term allocation signal transmitting unit 22, and an uplink data receiving unit 23.

The long-term communication parameter information transmitting unit 21 is configured to transmit long-term planning information (communication parameter information using long-term planning) to the mobile station UE, including a predetermined period and uplink radio resource information. Specifically, the long-term communication parameter information transmitting unit 21 is configured to transmit long-term scheduling information to the mobile station UE using the RRC message. The uplink radio resource information here is information imposing a restriction on the range of information values to be reported by the long-term allocation signal, i.e. a PDCCH (uplink scheduling grant) containing a command for long-term allocation of a PUSCH (uplink radio resource) for long-term scheduling. Since the description of the uplink radio resource information is the same as the description above for the mobile station UE, this description is not given here.

The long-term communication parameter information transmitting section 21 may set the uplink radio resource information based on the data type. For example, if the data type is VolP, then the long-term communication parameter information transmitting module 21 may, as information on the uplink radio resource, set information limiting the number of resource blocks to be reported by the resource block allocation information to 3 or less, and if if the data type is a stream, the module 21 for transmitting information about the parameters of long-term communication can set information limiting the number of uplink radio resource information your resource blocks to be reported through resource block allocation information of 10 or less.

Alternatively, if the data type is VolP, then the long-term communication parameter information transmitting module 21 may, as information on the uplink radio resource, specify information limiting the modulation scheme to be reported by the modulation and coding scheme information, the QPSK scheme, and if the type data is a stream, then the module 21 for transmitting information about the parameters of long-term communication can as information about the radio resource of the uplink communication set information limiting the modulation scheme, next aschuyu by post information about modulation and coding scheme, the scheme QPSK or 16QAM.

Alternatively, if the data type is VolP, then the long-term communication parameter information transmitting module 21 may, as information on the uplink radio resource, set information limiting the data size to be reported by modulation and coding scheme information to 320 bits, and if if the data type is a stream, then the module 21 for transmitting information about the parameters of long-term communication can specify information limiting the size of the data as information about the uplink radio resource, dlezhaschy by post information about modulation and coding scheme value of 640 bits. A specific method of limiting the range of information values to be reported by a long-term allocation signal, i.e. a PDCCH (uplink scheduling grant) containing a command for long-term allocation of a PUSCH (uplink radio resource) for long-term scheduling can be determined based on the type of data for which a resource is allocated by the long-term scheduling method. The concept of “data type” used above can also be interpreted as a “type of service”, that is, as information indicating the type of packet data service, which may be, for example, VolP service, voice service, data streaming service, file transfer service (FTP, File Transfer Protocol), etc.

In the above example, the long-term communication parameter information transmitting unit 21 sets the uplink radio resource information based on the data type, but instead of the data type, it can specify the specified uplink radio resource information based on the type of contract, logical channel type, cell type or priority type . The type of contract characterizes the contract concluded with the subscriber of the mobile station UE, and may be, for example, a contract of a basic type of service, a contract of a special type of service, a contract with a payment independent of the volume of services provided, a contract with a payment depending on the volume of services provided, and t .P.

A cell type is information about the functional characteristics of a cell, an example of which is the location of a cell indoors or outdoors, in a city or in a rural area, etc. The type of logical channel can be, for example, a dedicated control channel (Dedicated Control Channel, DCCH) or a dedicated data channel (Dedicated Traffic Channel, DTCH). In turn, several channels can be defined in the DCCH and DTCH.

A radio channel here is a radio data transmission channel, uniquely corresponding to a logical channel through which said data is transmitted. Accordingly, the concept of a radio channel has approximately the same meaning as the concept of a logical channel.

The priority type determines the priority level of the transmission of upstream and downstream data. For example, data with a first priority level during transmission takes precedence over data with a second priority level. The priority type can be combined with a logical channel and called the priority of the logical channel. Alternatively, the priority type may be called a priority class.

The long-term allocation signal transmission unit 22 is configured to transmit the long-term allocation signal to the mobile station UE. Specifically, the long term allocation signal transmission unit 22 is configured to transmit to the mobile station a UE as a long term allocation signal of a PDCCH (uplink scheduling grant) containing a command for long term allocation of a PUSCH (uplink radio resource) for long term scheduling. Moreover, if, for example, as described above, it is specified that the transmission power control information value shown in FIG. 2 is always 1 in the long-term allocation signal, then the long-term allocation signal transmission unit 22 can always be set as the transmission power control information value 1. Alternatively, if, for example, as described above, it is specified that in the long-term allocation signal, the cyclic shift value for the demodulation reference signal shown in FIG. 2 is always 1, then the signal transmitting unit 22 for long-term allocation as a cyclic shift value for DMRS can always set 1. Alternatively, if, for example, as described above, it is specified that the CQI request value shown in figure 2 is always 1 in the long-term allocation signal, then module 22 for transmitting a long-term allocation signal, the CQI can always be set to 1. As an option, if, for example, as described above, it is specified that the value of the new data indicator shown in FIG. 2 is always 1 in the long-term allocation signal, then the mode 22 s as the value of the new data indicator of long-term allocation of transmission signal can always set 1.

The uplink data receiving unit 23 is configured to receive uplink data to be transmitted via the PUSCH (uplink radio resource) allocated by the PDCCH. Specifically, the uplink data receiving unit 23 is configured to determine an uplink transmission subframe indicated by the PDCCH as an allocation start point if the long-term allocation signal transmission unit 22 is transmitted with a long-term allocation signal, and with a possibility of starting at the named start time of the allocation and the aforementioned predetermined period of long-term reception of uplink data through the channel PUSCH (uplink radio resource) for long-term planning.

The operation of a mobile communication system in accordance with a first embodiment of the present invention

Next, with reference to FIG. 5, operation of a mobile communication system in accordance with a first embodiment of the present invention is described.

As shown in FIG. 5, in step S101, the mobile station UE by means of an RRC message or the like. receives long-term scheduling information from the radio base station eNB, including the aforementioned predetermined period and uplink radio resource information. In this case, the information about the uplink radio resource is, for example, information that serves to limit the range of information values to be reported by a long-term allocation signal, i.e. a PDCCH (uplink scheduling grant) containing a command for long-term allocation of a PUSCH (uplink radio resource) for long-term scheduling. The description of the uplink radio resource information is the same as the description above for the mobile station UE and is not given here.

In step S102, the mobile station UE receives a long-term allocation signal transmitted by the radio base station eNB via the PDCCH. More specifically, the mobile station UE receives, from a radio base station eNB, a PDCCH (uplink scheduling grant) containing a command for long-term allocation of a PUSCH (uplink radio resource) for long-term scheduling as a long-term allocation signal.

In step S103, the mobile station UE checks whether the uplink radio resource information and the information reported by the long term allocation signal, i.e. channel PDCCH (uplink scheduling grant) containing a command for the long-term allocation of the channel PUSCH (radio resource uplink communication) for long-term planning. A detailed description of the compliance check operation is the same as that given above for the mobile station UE and is not given here. If the mobile station UE determines that the uplink radio resource information and the information reported by the long term allocation signal, i.e. channel PDCCH (uplink scheduling grant) containing the command for the long-term allocation of the channel PUSCH (radio resource uplink communication) for long-term planning, do not match each other (step S103: YES), the process goes to step S104.

In step S104, the mobile station UE refuses to use the long-term allocation signal, i.e. a PDCCH (uplink scheduling grant) containing a command for long-term allocation of a PUSCH (uplink radio resource) for long-term scheduling. Specifically, the mobile station UE recognizes the information communicated by the long-term allocation signal, i.e. a PDCCH (uplink scheduling grant) containing a command for long-term allocation of a PUSCH (uplink radio resource) for long-term scheduling addressed to a non-given mobile station UE.

In step S105, the mobile station UE determines, as the aforementioned start time of the allocation, the uplink transmission subframe indicated by the long-term allocation signal, i.e. channel PDCCH (uplink scheduling grant) containing a command for long-term allocation of the channel PUSCH (radio resource uplink communication) for long-term planning, and then from the moment the allocation starts in step S105 with a predetermined period begins long-term transmission of uplink data through the channel PUSCH (radio resource uplink) for long-term planning.

In this case, the mobile station UE transmits uplink data via the PUSCH (uplink radio resource) for long-term scheduling until the aforementioned PUSCH (uplink radio resource) for long-term scheduling is released.

The technical result of a mobile communication system in accordance with the first embodiment of the present invention

In accordance with the foregoing, the probability of a false positive for one PDCCH (uplink scheduling grant or downlink scheduling information) is 1/2 ¹⁶ . Since the mobile station UE, as a rule, attempts to decode approximately 40 PDCCHs in one subframe, the resulting false alarm probability is 40 × 1/2 ¹⁶ = 0,0006.

The aforementioned false positive is a situation in which the mobile station UE recognizes the received PDCCH as being addressed to this mobile station UE, although said PDCCH was not really addressed to this mobile station UE. In such a situation, the decoded information is highly likely to be meaningless. As described above, a restriction is made on the range of information values in the PDCCH, and if the mobile station UE receives a PDCCH with information outside the limited range, then the mobile station UE refuses to use the specified channel PDCCH, so that the likelihood of false response can be significantly reduced. For example, suppose that the number of bits in a non-CRC PDCCH is 24, and in the specified 24 bits, the limitation is on the 12-bit range. For simplicity of calculations, we also assume that the use of the specified configuration of 12 bits is limited to the transmission of information of the same type. If the mobile station UE receives a PDCCH with information that is outside the range of the range described above, then the mobile station UE performs an operation of not using said PDCCH information. The probability of false alarm, calculated as 40 × 1/2 ¹⁶ × 1/2 ^12/2 = 1,5 × ^{24 -7} 10, in this case, considerably lower.

Specifically, the mobile communication system in accordance with the first embodiment of the present invention makes it possible to reduce the likelihood of a false positive when decoding a PDCCH (uplink scheduling grant) reporting resource allocation for long-term scheduling. Thus, the mobile communication system in accordance with the first embodiment of the present invention makes it possible to implement a reliable and efficient method of mobile communication, a mobile station and a radio base station.
