Description

Method for transmitting control information and base station and user equipment

Technical field

The embodiments of the present invention relate to the field of communications, and in particular, to a method for transmitting control information, a base station, and a user equipment.

Background technique

In the Release-13 specification of the prior art, the maximum supported bandwidth of the Downlink Control Information (DCI) format 6-1A (or 6-0A) can only be one narrowband, and one narrowband corresponds to continuous. The six physical resource blocks, the current DCI format6-1A (or 6-0A), can support a maximum transport block size of 1000 bits.

For example, the Rel-13 DCI format 6-1A resource allocation is used as an example. In the existing system, DCI format 6-1A is included.

The bits are used to indicate the narrowband index value of the resource allocation in the system bandwidth, and the last 5 bits in the DCI format 6-1A resource block allocation field are used to indicate the allocated physical resource blocks within the indicated narrowband, where

Indicates the number of all physical resource blocks included in the downlink system bandwidth. For the allocation of the physical resource blocks in the narrowband, according to the resource allocation mode of the starting point combined with the length, the allocation of the physical resource blocks in the narrowband has a maximum of 21 resource allocation situations. Therefore, if the allocation of the physical resource blocks in the narrowband corresponds to the bit b ₄ b ₃ b ₂ b ₁ b ₀ , its value can only be from 00000 to 10101.

In the prior art, the base station is a low-complexity user equipment with a reduced bandwidth or a resource allocation manner of the coverage enhanced user equipment, and can only indicate a specific narrowband in the system bandwidth and the allocation of the corresponding physical resource block in the narrowband. Low-complexity user equipment or coverage-enhanced user equipment with reduced bandwidth can only support a maximum of 1000 bits of transport block size, for Time Division Duplex (TDD) or Half Duplex-Frequency Division Duplex (Half Duplex-Frequency Division Duplex, In the HD-FDD system, since the uplink transmission and the downlink transmission are time-division transmission, 10 subframes in one radio frame cannot be used as the uplink subframe or the downlink subframe, so that the peak rate of data transmission is lower than the Rel-13 specification. The expected 1 megabit per second (Mbps).

According to the requirements of the Rel-13 DCI format 6-1A (or 6-0A) in the prior art, the user equipment can support When the maximum bandwidth is greater than one narrowband, the existing resource allocation mode cannot indicate a resource allocation scenario greater than one narrowband. For TDD or HD-FDD systems, the peak rate of data transmission is lower than the 1 Mbps expected by Rel-13, so some medium-rate Machine Type Communication (MTC) services cannot be supported.

In order to make the object, the features and the advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. The described embodiments are only a part of the embodiments of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of the present invention.

First, the system architecture of the method for transmitting control information of the present invention is introduced. The present invention is mainly applied to an LTE system or an advanced long-term evolution (LTE-A, LTE Advanced) system. The present invention can also be applied to other communication systems, for example, Wideband Code Division Multiple Access (WCDMA), Time Division-Synchronous Code Division Multiple Access (TD-SCDMA), and the like. As long as there is an entity in the communication system that can send information, other entities in the communication system can receive the information.

In the embodiment of the invention, the transmission may be transmission or reception. If the transmission of the one side device is the transmission, the processing of the other side communication device corresponding to the side device is the receiving; if the transmission of the one side device is the receiving, the processing of the other side communication device corresponding to the side device is the sending; vice versa.

The working bandwidth may be one or more of processing bandwidth, radio frequency processing bandwidth, and baseband processing bandwidth. For example, the operating bandwidth is 1.4 MHz (or 200 KHz, or 180 KHz). The working bandwidth is a frequency resource with a specific frequency width. The working bandwidth may be composed of one or more subcarriers (eg, a subcarrier size of 15 Khz, or 2.5 KHz, or 3.75 KHz), or may be composed of one or more resource blocks.

Referring to FIG. 1 , a system architecture diagram of a method for transmitting control information according to the present invention is applied to a communication system, as shown in FIG. 1 , a base station (English name Base station) and a user equipment (User Equipment, UE) 1 to The UE 6 constitutes a communication system, in which the base station transmits one or more of system information, RAR message and paging message to one or more UEs of UE1 to UE6, and the base station transmits the control information of the present invention. The transmitting end device in the method, UE1 to UE6, is a receiving end device in the method for transmitting control information of the present invention. In addition, UE4 to UE6 also form a communication system, in which UE5 can be implemented as a function of a base station, and UE5 can send one or more of system information, control information, and paging message to UE4 and UE6. One or more UEs.

The details are described below separately.

An embodiment of the method for transmitting control information of the present invention is applicable to a scenario in which a base station sends control information to a UE, and adopts the same downlink control information format without adding control information bits, and can support indication of narrowband resources. The allocation can also support resource allocation indicating larger bandwidth, and can also support indicating a larger transport block size, avoiding newly added bit overhead, and improving the flexibility of resource indication. Referring to FIG. 2, the method for transmitting the control information may include the following steps:

201. The downlink control information carries indication information, where the indication information includes N bits, and a position of the N bits in the indication information corresponds to a position of N bits in the first field.

Wherein, N is a natural number greater than or equal to 2 and less than or equal to 5, the first field includes 5 bits, and the first field is a field indicating resource allocation in the narrowband in the first resource allocation information, according to the first resource allocation The number of physical resource blocks allocated by the information is less than or equal to the first physical resource block threshold, and the transport block size determined according to the number of physical resource blocks allocated according to the first resource allocation information is not greater than the first transport block threshold.

In the embodiment of the present invention, the base station serves the UE, and the UE may specifically include a Machine Type Communication (MTC) user equipment, that is, a low complexity user equipment, or a low power consumption user equipment, or an enhanced user equipment. . Generally, the low-complexity user equipment or the low-power MTC user equipment supports a working bandwidth smaller than that of a normal user equipment. In the embodiment of the present invention, the number of physical resource blocks allocated according to the first resource allocation information is less than or equal to the first physical resource block threshold, and the transport block size determined according to the number of physical resource blocks allocated according to the first resource allocation information is not greater than the first transport block. The threshold, the resource allocation information that meets the two conditions that the number of physical resource blocks is less than or equal to the first physical resource block threshold, and the determined transport block size is not greater than the first transport block threshold is specifically the first resource allocation information described in the embodiment of the present invention. And the first resource allocation information includes a first field, where the first field is capable of determining how to perform resource allocation in the narrowband according to the first resource allocation information. Therefore, the foregoing indication information may be generated by the location of the N bits in the indication information and the location of the N bits in the first field, where the indication information is carried by the base station in the downlink control information, and the number of bits included in the indication information cannot exceed 5.

In some embodiments of the invention, the first physical resource block threshold is six and the first transport block threshold is 1000 bits. The threshold values of the first physical resource block and the threshold value of the first transport block are not limited in the embodiment of the present invention. For the different application scenarios of the downlink control information, the two types of thresholds may be flexibly configured.

By way of example, the following is a low complexity of the bandwidth reduction described in the Rel-13 specification in the prior art. The number of physical resource blocks that can be allocated in the current scheme for resource allocation and the determined transport block size are all limited, so that no more physical resources can be supported in the prior art. In the embodiment of the present invention, the original downlink control information format is not changed, and the downlink control information carries the indication information, where the position of the N bits of the indication information in the indication information corresponds to the first The position of N bits in a field, but the N bits of the indication information can support both the indication of narrowband resource allocation and the resource allocation indicating larger bandwidth, and also support the indication of a larger transport block size, among N bits. The value of a bit state is not limited and can be configured according to the resource configuration indicated. Specifically, in a case where the state of at least one of the N bits of the indication information is 0, in accordance with the trigger condition of step 202, step 202 may be performed, and the state of each bit of the N bits of the indication information is 1. In the case that the trigger condition of step 203 is met, step 203 can be performed.

202. When the state of at least one of the N bits is 0, the downlink resource information carries the first resource allocation information, where the indication information is N bits of the 5 bits included in the first field.

In the embodiment of the present invention, the resource allocation information that satisfies the two conditions that the number of physical resource blocks is less than or equal to the first physical resource block threshold, and the determined transport block size is not greater than the first transport block threshold is specifically described in the embodiment of the present invention. The first resource allocation information, by indicating that the state of the at least one of the N bits of the information is 0, the base station needs to transmit the first resource allocation information to the user equipment, where the indication information may be the 5 bits included in the first field. N bits. For example, the high N bits of the 5 bits included in the first field may constitute the indication information, or the lower N bits of the 5 bits included in the first field may constitute indication information, which is not limited herein.

In some embodiments of the present invention, the first resource allocation information is specifically: a narrowband index field and a first field; wherein the narrowband index field indicates an index value of the narrowband.

For example, the Rel-13 DCI format 6-1A resource allocation is used as an example. The DCI format 6-1A is included.

The number of at least one physical resource block allocated according to the third resource allocation information is greater than the first physical resource block threshold.

Other resource allocation information. For convenience of description, in the embodiment of the present invention, when the status of each bit in the indication information is 1, the base station needs to transmit the second resource allocation information or the third resource allocation information to the user equipment, so the second resource allocation information or the The three resource allocation information is carried in the downlink control information.

The first transport block threshold may be 1000 bits. Similarly, the number of at least one physical resource block allocated according to the third resource allocation information is greater than the first physical resource block threshold, that is, the number of physical resource blocks allocated according to the third resource allocation information has at least two. Therefore, the number of physical resource blocks allocated by the third resource allocation information may be greater than the threshold of the first physical resource block, but the number of physical resource blocks allocated by the third resource allocation information is not required to be greater than the first physical resource. The source block threshold is intended to indicate that the number of one or several physical resource blocks allocated by the third resource allocation information is greater than the first physical resource block threshold, but the number of other physical resource blocks allocated by the third resource allocation information may still be less than or Equal to the first physical resource block threshold.

Therefore, the transport block size determined by the number of physical resource blocks allocated by the second resource allocation information may be greater than the first transport block threshold, but the transport block size determined by the number of physical resource blocks allocated by the second resource allocation information is not required to be greater than the first transmission. Block threshold.

The first transport block threshold may be 1000 bits. Similarly, the number of at least one physical resource block allocated according to the third resource allocation information is greater than the first physical resource block threshold. That is, the number of physical resource blocks allocated according to the third resource allocation information has at least two types, and thus the number of physical resource blocks allocated by the third resource allocation information may be greater than the first physical resource block threshold, but the third resource allocation is not required. The number of physical resource blocks allocated for information must be greater than the first physical resource block threshold. The intention is to indicate that the number of one or several physical resource blocks allocated by the third resource allocation information is greater than the first physical resource block threshold, but the number of other physical resource blocks allocated by the third resource allocation information may still be less than or equal to the first physical Resource block threshold.

The base station can When the control information bit is not added, the same downlink control information format is adopted, which can support the indication of narrowband resource allocation and the resource allocation indicating larger bandwidth, and can also support indicating a larger transport block size and avoid new addition. The bit overhead increases the flexibility of resource indication.

The second field includes (5-N) or M=(4-N) bits, that is, the indication information and the second field occupy 5 or 4 bits, and the second field is used to indicate within the indicated narrow band. Allocated physical resource blocks, where

M is a predetermined positive integer. For example, M=(5-N) or M=(4-N).

Specifically, the second resource is included in the second resource allocation information and the third resource allocation information, but the first bit state set and the second bit state set in the third field may indicate different means of resource allocation, if the base station A first set of bit states is used in the third field, each bit state in the first set of bit states of the third field indicating resource allocation within the narrow band. If the base station is in the third word The second bit state set is used in the segment, and each bit state in the second bit state set of the third field indicates the number of narrowband allocations. The number of narrowband bands allocated is exemplified in the following embodiments.

Indicates that different types of resource classification methods are used for narrowband allocation of different channels. Preferably, (K+M) bits indicate narrowband allocation of the uplink shared channel according to the Type 2 resource allocation type, and (K+M) bits according to Type 0 resources. The allocation type indicates a narrowband resource allocation of the downlink shared channel.

According to the foregoing description of the present invention, the downlink control information sent by the base station is received by using the first downlink control information format, where the downlink control information is used to schedule an uplink shared channel or a downlink shared channel, and the indication information is obtained from the downlink control information. Wherein the indication information includes N bits, and N is a natural number greater than or equal to 2 and less than or equal to 5.

The number of physical resource blocks allocated according to the first resource allocation information is less than or equal to the first physical resource block threshold, and the transport block size determined according to the number of physical resource blocks allocated according to the first resource allocation information is not greater than the first transport block threshold. When the state of at least one of the N bits is 0, the first resource allocation information is acquired from the downlink control information, and the indication information is N bits out of the 5 bits included in the first field.

The number of at least one physical resource block allocated according to the third resource allocation information is greater than the first physical resource block threshold. The downlink control information can adopt the same downlink control information format without adding bits, and can support both narrowband resource allocation and resource allocation indicating larger bandwidth, and can also support indicating a larger transport block size. The medium-rate MTC service can also be supported, avoiding the newly added bit overhead, and improving the flexibility of resource indication.

To facilitate a better understanding and implementation of the foregoing solutions of the embodiments of the present invention, the following application scenarios are specifically illustrated. The method for transmitting control information provided by the embodiment of the present invention is used for how to allocate resources of a larger bandwidth (for example, more than 6 physical resource blocks). The embodiment of the present invention can reuse the DCI format of the Enhanced Machine-Type Communications (eMTC) (eg, 6-0A/1A) Differentiate between narrowband resource allocation and larger bandwidth resource allocation, and/or DCI format (eg, 6-0A/1A) that multiplexes eMTC indicates a larger TBS. When the embodiment of the present invention supports a larger bandwidth resource allocation and/or a larger transport block size (TBS), the low-complexity user equipment of the bandwidth reduction or the downlink control information format of the coverage enhanced user equipment is indicated in the narrowband The high (or low) N bits of the 5 bits of the resource allocation are all set to 1, N is a positive integer, and N is greater than or equal to 2, such as N is equal to 2 or 3. A larger resource allocation is performed in units of narrow bands (continuous G physical resource blocks, such as G equal to 5). The initial narrow band is indicated first, and then the specific number of narrow bands used for information transmission is indicated. When the resource allocation is less than or equal to a narrow band, the resource allocation is performed by using Rel-13 DCI format 6-0A, DCI format 6-1A, DCI format 6-0B, or DCI format 6-1B, when the allocated resource may be larger than a narrow band. At the time, the technical solution of the present invention is used to indicate resource allocation. When the downlink control information indicates a larger TBS, the TBS is determined according to the 4-bit or 5-bit or 3-bit MCS field.

In the existing DCI format 6-0A or DCI format 6-1A,

or

Indicates the index of the narrowband, usually a narrow band consisting of 6 consecutive physical resource blocks. Further, the first field of 5 bits indicates the resource allocation within the indicated narrow band.

FIG. 4 is a schematic diagram of an application scenario for resource allocation by using DCI format 6-1A according to an embodiment of the present invention. If DCI format 6-0A or DCI format 6-1A is used for allocation of physical resource blocks in a narrowband, for the uplink resource allocation, the resource allocation method of the starting point combined length is Type 2 resource allocation information, and for the downlink resource allocation, the starting point is combined. The resource allocation method of the length is type 0Type 0 resource allocation information. In the prior art, DCI format 6-0A or DCI format 6-1A allocates up to 21 cases of narrow-band physical resource blocks, that is, a state of 5 bits indicating the allocation of physical resource blocks in a narrowband b ₄ b ₃ b ₂ b ₁ b _{0 is} up to 21 cases of 00000 to 10101.

For resource allocation of low-complexity user equipment or coverage enhanced user equipment with reduced bandwidth in the Rel-13 specification, it is impossible to have a narrow-band physical resource block of "11b ₂ b ₁ b ₀ " or "111b ₁ b ₀ " Assign status. Therefore, in DCI format 6-0A or DCI format 6-1A, when the bit state of the high (or low) N-bit bit in the 5-bit field corresponding to the physical resource block allocation in the narrowband is all one, the downlink control may be indicated. Information is resource allocation for larger bandwidth or indicates a larger transport block size, where N is a positive integer, N is greater than or equal to 2, and N is less than 5.

It should be noted that the downlink control information used for resource allocation of a larger bandwidth means that the resource allocation of the downlink control information may exceed 6 RBs, but it does not mean that the resource allocation of the downlink control information always exceeds 6 RBs. Similarly, the downlink control information is used to indicate that the larger transport block size means that the TBS indicated by the downlink control information may exceed 1000 bits, but it does not mean that the TBS indicated by the downlink control information always exceeds 1000 bits.

As shown in FIG. 4, DCI format 6-1A may indicate resource allocation within a narrow band, and may also indicate resource allocation for a larger bandwidth. The UE determines the status bit b ₄ b _3, if the status bit b ₄ b ₃ is not all 1, the UE determines a resource allocation according to the first resource allocation information, wherein the first resource allocation information resources must not exceed 6 RB That is, the first resource allocation information is resource allocation within a narrow band. For PUSCH resource allocation, the first resource allocation information is a Type 2 resource allocation, and for PDSCH resource allocation, the first resource allocation information is a Type 0 resource allocation.

If the bit status of b ₄ b ₃ is all 1, the UE determines the allocated resource according to the third resource allocation information, wherein the resource allocated by the third resource allocation information may exceed 6 RBs. That is, the third resource allocation information can support resource allocation of a larger bandwidth.

As shown in FIG. 5, the DCI format 6-0A can be used to indicate a transport block size of no more than 1000 bits, and can also indicate a transport block size of more than 1000 bits. In FIG. 5, the UE determines the status bit b ₄ b _3, if the status bit b ₄ b ₃ is not all 1, the UE determines the modulation coding method according to the TBS field of the downlink control information and the TBS determining a first embodiment. The TBS determined by the UE according to the first TBS determination manner must not exceed 1000 bits. If the bit status of b ₄ b ₃ is all 1, the UE determines the TBS according to the modulation coding method field and the second TBS determination manner in the downlink control information. The TBS determined by the UE according to the second TBS determination manner may exceed 1000 bits. The TBS determination mode refers to determining the TBS according to resource allocation, modulation coding mode, and TBS table.

As shown in FIG. 6, DCI format 6-0A is used, indicating: resource allocation in a narrow band and a transport block size of not more than 1000 bits, resource allocation in a narrow band, and a transport block size exceeding 1000 bits, and a resource having a larger bandwidth. distribution. In FIG. 6, if the bit state of b ₄ b ₃ is not all ones, the UE determines the TBS according to the modulation coding method field in the downlink control information and the first TBS determination manner. The TBS determined by the UE according to the first TBS determination manner must not exceed 1000 bits. And the UE determines the allocated resource according to the first resource allocation information, where the resource allocated by the first resource allocation information does not exceed 6 RBs. That is, the first resource allocation information is resource allocation within a narrow band.

In FIG. 6, UE determines the status bit b ₄ b _3, if the status bit b ₄ b ₃ are all 1, according to the UE downlink control information b _2, b _1, b ₀ of the three bits The state determination determines whether the TBS is determined by the second resource allocation information and the second TBS determination manner, or determines the TBS by using the third resource allocation information to determine the resource allocation and the third TBS determination manner. Some states of the three bits b ₂ , b ₁ , and b ₀ indicate that the UE determines the TBS by using the second resource allocation information to determine the resource allocation and the second TBS determining mode. The other states of the three bits b ₂ , b ₁ , and b ₀ indicate that the UE determines the resource allocation using the third resource allocation information and the third TBS determination mode determines the TBS.

The third TBS determination manner is different from the second TBS determination manner. The definitions of the first resource allocation information, the third resource allocation information, and the second TBS determination manner are as described above. For example, in FIG. 6, when the state of b ₂ , b ₁ , and b ₀ is any one of 000 to 011, it is determined that the resource allocation is determined using the second resource allocation information, and the TBS is determined using the second TBS determination manner. When the state of b ₂ , b ₁ , and b ₀ is any one of 100 to 111, it is determined that the third resource allocation information is used to determine the resource allocation, and the third TBS determination manner is used to determine the TBS.

The implementation manner of the third resource allocation information in the embodiment of the present invention is exemplified. For example, the third resource allocation information may include the following three methods:

Method 1: First indicate the index of the narrowband, and then indicate the narrowband as the starting point of the resource allocation, and indicate the number of narrowbands allocated to the UE.

The UE may perform PUSCH transmission or PDSCH reception on all RBs included in the allocated narrowband. Correspondingly, the base station can perform PUSCH reception or PDSCH transmission on all RBs included in the allocated narrowband.

E.g:

PUSCH resource block allocation

Bits indicate a narrowband index;

The status of 2 bits is fixed at 11;

3 or 2 bits indicate the number of narrow bands.

PDSCH resource block allocation

Bits indicate a narrowband index;

The status of 2 bits is fixed at 11;

3 or 2 bits indicates the number of narrow bands.

The narrowband index described above may be the starting narrowband index. In an embodiment of the invention, a narrow band is composed of H consecutive physical resource blocks. Such as H=6, or H=5. use

or

The bits indicate one of the 2 ^k narrow bands. The index of the starting narrowband is NB _i , where i = 0, 1, ..., 2 ^k -1. For H = 5, for system bandwidth of 20MHz, a total of 20 narrow-band, but the base station may indicate only the first 16 narrow band (i.e., NB ₀ ~ NB ₁₅₎ narrowband index. This ensures that regardless of H=5 or H=6, it can be used.

or

The bits indicate a narrow band of the 16 narrow bands.

The state of the two bits is fixed at 11 to indicate that the downlink control information is for larger bandwidth scheduling. The 3 bits indicating the number of narrow bands are used to indicate the number of narrowbands allocated to the PUSCH transmission or PDSCH transmission of the UE.

Tables (1-a) and (1-b) below list two possible indication relationships when 3 bits indicate the number of narrow bands. For example, in the table (1-a), one narrowband NB _i includes 6 RBs, and if the starting NB _i narrowband includes RB indexes of PRB _n , PRB _n+1 , PRB _n+2 , PRB _n+3 , PRB _{n +4} , PRB _n+5 . If the number of the 3 bits indicating the number of narrowband indications is 3/2, the base station allocates a total of 1.5 narrowbands with the NB _i as the starting narrowband (including the initial narrowband), that is, the RB allocated by the base station to the UE is _{_{PRB n, PRB n + 1,}} PRB n + 2, PRB n + 3, PRB n + 4, PRB n + 5, PRB n + 6, PRB n + 7, PRB n + 8. If the index of the RB allocated by the base station for the UE exceeds the RB index with the largest system bandwidth, the index of the RB actually used by the UE is the number of all RBs corresponding to the index mod system bandwidth of the RB pre-allocated by the UE, where mod is a modulo operation.

Of course, it is also possible to use a 3-bit state fixed to 111 to indicate that the downlink control information is for larger bandwidth scheduling. Only two bits can be indicated at this time to indicate the number of narrow bands.

E.g:

PUSCH resource block allocation

Bits indicate a narrowband index;

The status of 3 bits is fixed at 111;

2 or 1 bits indicate the number of narrow bands.

PDSCH resource block allocation

Bits indicate a narrowband index;

The status of 3 bits is fixed at 111;

2 or 1 bits indicates the number of narrow bands.

Method 2: First indicate an index of the narrowband, and then indicate that the indicated narrowband is a starting narrowband for resource allocation, and allocate resources for the UE within the G narrowband resources.

E.g:

PUSCH resource block allocation

Bits indicate a narrowband index;

The status of 2 bits is fixed at 11;

3 or 2 bits indicate that resources are allocated for the UE within the G narrowband resources.

PDSCH resource block allocation

Bits indicate a narrowband index;

The status of 2 bits is fixed at 11;

3 or 2 bits indicates that resources are allocated for the UE within the G narrowband resources.

The method of indicating the index of the narrow band is as described in the method 1, and will not be described again here. Considering 3MHz, 5MHz, 10MHz, 15MHz, the number of RBs included in 20MHz is a multiple of 5, and it can be specified that a narrow band contains 5 RBs, that is, H=5.

As described in Method 1, the 2 bit state is fixed to 11 to indicate that the downlink control information is for a larger bandwidth adjustment. Degree.

3 or 2 bits indicates that resources are allocated for the UE within the G narrowband resources. The size of G is predetermined, such as G=3, or 5, or 10. Allocating resources for the UE in the G narrowband resources refers to a narrowband starting with the indicated narrowband, and allocating resources for the UE in the narrowbands of the starting narrowband (the G narrowbands include the initial narrowband).

As shown in FIG 7, for 20MHz system bandwidth, comprising a narrow band 20, but for a narrow band index indicating any one of 0 to 15, a narrow band (NB _i denotes an index of a narrowband i, i = 0, ......, 15 ).

For example, three bits b ₂ b ₁ b ₀ indicate resource allocation within five narrow bands starting with NB _i as a narrow band. Table 3 below lists resource allocation information within G = 5 narrow bands.

b₂,b₁,b₀ b ₂ , b ₁ , b ₀	窄带分配Narrowband allocation
000000	NB_i,NB_i+1 NB _i , NB _i+1

100100	NB_i+2,NB_i+3，NB_i+4 NB _i+2 , NB _i+3, NB _i+4
101101	NB_i,NB_i+1，NB_i+2，NB_i+3 NB _i , NB _i+1, NB _i+2, NB _i+3
110110	NB_i+1，NB_i+2，NB_i+3，NB_i+4 NB _i+1, NB _i+2, NB _i+3, NB _i+4
111111	NB_i,NB_i+1，NB_i+2，NB_i+3，NB_i+4 NB _i , NB _i+1, NB _i+2, NB _i+3, NB _i+4

Method 3: The downlink control information indicates that the resource allocation of the larger bandwidth is based on the narrowband, and the resource allocation method of the starting point combined with the length is used for resource allocation of the larger bandwidth.

In the existing LTE system, for the uplink resource allocation, the resource allocation method of the starting point combined length is Type 2 resource allocation information. For downlink resource allocation, the resource allocation method of the starting point combined length is Type 0 resource allocation information.

In method 3, each narrow band includes H physical resource blocks. For different system bandwidths, H can be the same or different. For example, for 3MHz, 5MHz, 10MHz, 15MHz, 20MHz system bandwidth, H=6. For another example, for 3MHz, 5MHz, 10MHz, 15MHz system bandwidth, H = 5; and for 20MHz system bandwidth, H = 6. For another example, for 3MHz, 5MHz, 10MHz, 15MHz system bandwidth, H = 5; and for 20MHz system bandwidth, H = 10.

It should be noted that for a system bandwidth of 20 MHz, if H=6, there are a total of 16 narrow bands. According to the resource allocation method of the starting point combined with the length, when the resource allocation of the larger bandwidth is performed within the system bandwidth of 20 MHz, the minimum bandwidth allocation of the larger bandwidth is 2 narrow bands, that is, the minimum resource allocation is 2 narrow bands. For other system bandwidths, a similar rule can be made, that is, the minimum length of the allocation of larger bandwidth resources is L narrow bands, where L is an integer greater than 1 (for example, L=2). When L=2, Log2(A*(A-1)/2) bits are required to indicate a larger bandwidth resource allocation (a resource allocation method according to the starting point combined length), where A is the total number of narrowbands included in the system bandwidth.

For the downlink larger bandwidth resource allocation: A = floor(log2(N _DL ^RB /H)), where floor is the round-down function and N _DL ^RB is the number of RBs included in the downlink bandwidth. Alternatively, A=ceil(log2(N _DL ^RB /H)), where ceil is a round-down function and N _DL ^RB is the number of RBs included in the downlink bandwidth.

For the uplink larger bandwidth resource allocation: A = floor(log2(N _UL ^RB /H)), where floor is the round-down function and N _UL ^RB is the number of RBs included in the upstream bandwidth. Alternatively, A=ceil(log2(N _UL ^RB /H)), where ceil is a round-down function and N _UL ^RB is the number of RBs included in the uplink bandwidth.

E.g:

PUSCH resource block allocation

The bits indicate narrowband resources according to Type 2;

The status of bits is fixed to all 1s;

The bits indicate narrowband resources according to Type 2.

PDSCH resource block allocation

The bits indicate narrowband resources according to Type 0;

The status of bits is fixed to all 1s;

The bits indicate a narrowband resource according to Type 0.

E.g:

PUSCH resource block allocation

The bits indicate narrowband resources according to Type 2;

The status of bits is fixed to all 1s;

The bits indicate narrowband resources according to Type 2.

PDSCH resource block allocation

The bits indicate narrowband resources according to Type 0;

The status of bits is fixed to all 1s;

The bits indicate a narrowband resource according to Type 0.

The first downlink control information format corresponds to the K bit indicating the narrowband index, and the M bits in the 5-bit position corresponding to the field indicating the resource allocation in the narrowband in the first downlink control information format constitute K+M Bits, this K+M bits use a starting point combined with a length of resource allocation method for larger bandwidth resource allocation.

For downlink resource allocation with greater bandwidth,

For the allocation of resources with higher bandwidth,

M=Log2(A*(A+1)/2)-K or M=Log2(A*(A-1)/2)-K. Alternatively, M = Log2(A*(A+1)/2)-K-1 or M=Log2(A*(A-1)/2)-K-1.

As shown in Figure 8 and Figure 9,

or

When M=3, the narrowband allocation of PUSCH or PDSCH. Of course, M can also be equal to 2, in which case the 3 bits b4, b3, and b2 are fixed to 111 to indicate that the downlink control information is a resource allocation for a larger bandwidth.

The second resource allocation information in the embodiment of the present invention is exemplified. For example, the second resource allocation information may adopt the following method: first indicating a narrowband index, and then indicating resource allocation in a narrowband.

E.g:

PUSCH resource block allocation

Bits indicate a narrowband index;

The state of N bits is fixed to all 1s;

M bits indicate resource allocation within a narrow band.

PDSCH resource block allocation

Bits indicate a narrowband index;

The state of N bits is fixed to all 1s;

M bits indicate resource allocation within a narrow band.

Wherein, the indication of the narrowband index is as explained in the foregoing embodiment.

N all 1 bits are used to indicate that the downlink control information indicates a larger TBS. The size of N is predetermined, and N is greater than or equal to 2 and less than or equal to 5. If N=5, then no bit indicates resource allocation in the narrowband, and at this time, 6 RBs in the default narrowband are used for PUSCH or PDSCH transmission.

M bits indicate resource allocation within a narrow band. M is a predetermined positive integer. For example, M=(5-N) or M=(4-N). For example, N=4, then 1 bit indicates resource allocation within the narrow band. It is assumed that the indicated narrowband includes RBs: PRB _i , PRB _i+1 , PRB _i+2 , PRB _i+3 , PRB _i+4 , PRB _i+5 . One bit can indicate the RB allocation within the narrowband according to the following table. As shown in Table 7 below,

As shown in Table 8 below, N = 3, 2 bits indicates resource allocation within the narrow band.

Next, the indication information is used to indicate the third resource allocation information or the second resource allocation information. E.g:

PUSCH resource block allocation

Bits indicate a narrowband index;

The state of N bits is fixed to all 1s;

M bits indicate the resource allocation or the number of narrow bands within the narrow band.

PDSCH resource block allocation

Bits indicate a narrowband index;

The state of N bits is fixed to all 1s;

N all 1 bits are used to indicate that the downlink control information indicates a larger TBS or a larger bandwidth allocation. The size of N is predetermined, and N is greater than or equal to 2 and less than 5. Certain bit states in the M bits indicate resource allocation within the narrow band. Other bit states in the M bits indicate the number of narrow bands. M is a predetermined positive integer. For example, M=(5-N) or M=(4-N).

As shown in Table 9 below, if the state of the N bits is all ones and some of the bit states in the M bits indicate resource allocation within the narrowband, the downlink control information indicates a larger TBS. If the state of the N bits is all ones and some of the bit states in the M bits indicate the number of narrowbands, the downlink control information indicates a larger bandwidth allocation.

Next, the second TBS determination mode will be exemplified.

The transport block size is determined according to the second TBS determination manner according to the number of RBs allocated according to the second resource allocation information in the downlink control information and the downlink modulation and coding scheme indicated in the downlink control information. The table below gives a second TBS determination. Where I _TBS is the index of TBS, I _TBS =I _MCS . The I _MCS is an index of the modulation and coding mode indicated by the downlink control information. N _PRB is the number of RBs allocated according to the second resource allocation information. The _{TBS of the} PUSCH or PDSCH transmission can be determined by checking the following table according to I _TBS and N _PRB . For example, shown in Table 10 below.

Or determine the TBS according to the TBS table in the existing standard according to I _TBS and fun (N _PRB , Y). Fun(N _PRB , Y) is a function of N _PRB and Y. For example, Y=4, fun(N _PRB , Y)=N _PRB +4. Or determine the TBS according to the TBS table in the existing standard according to I _TBS =fun(I _MCS ,Z) and N _PRB . Z is a predetermined positive integer. For example, Z=8, I _MCS =fun(I _MCS ,Z)=I _MCS +8.

The embodiment of the present invention can distinguish the resource allocation in the narrowband and the resource allocation in the larger bandwidth in the DCI format 6-0A or the DCI format 6-1A without increasing the bit overhead. The bit overhead and the newly defined downlink control information format are avoided, and the flexibility of resource indication is improved.
