Description

Resource allocation method and device

Technical Field

The present application relates to the field of communications, and in particular, to a method and an apparatus for resource allocation.

Background

Machine Type Communication (MTC) refers to acquiring information of the physical world by deploying various devices with certain sensing, computing, executing and Communication capabilities, and implementing information transmission, coordination and processing through a network, thereby implementing human-to-object and object-to-object interconnection. At present, the Rel (release) -12, Rel-13 and Rel-14 versions of Long Term Evolution (LTE) can support MTC services.

In LTE Rel-13, a terminal (UE) capable of supporting MTC services is a Bandwidth-reduced Low-complexity UE (BL UE) or a Coverage Enhancement UE (CE UE), and its maximum supportable transmission and reception Bandwidth is 1.4MHz or a Narrow Band (NB). A narrow band contains the frequency width of 6 consecutive Physical Resource Blocks (PRBs) in frequency. To enable MTC to support higher data rates, LTE Rel-14 Further enhances MTC, referred to as Further Enhanced Machine-Type Communication (fesmtc). In LTE Rel-14, a bandwidth that can be supported by a UE performing MTC services and is used for transmitting service data is extended, that is, a Physical Uplink Shared Channel (PUSCH) bandwidth of 5MHz is supported, and a Physical Downlink Shared Channel (PDSCH) bandwidth of 5MHz or 20MHz is supported.

When allocating resources for BL UEs or CE UEs, the conventional LTE Rel-13 can only indicate a specific narrow band in the system bandwidth and indicate PRB allocation in the narrow band. I.e. the frequency width of the allocated resources does not exceed a narrow band, or 1.4 MHz. However, the MTC service of LTE Rel-14 supports larger PUSCH and PDSCH bandwidths, the frequency width of the resource required to be allocated can reach 5MHz or 20MHz, and at this time, the frequency width exceeds one narrow band, and the existing resource allocation scheme cannot meet the requirement of resource allocation.

Optionally, the resource block allocation information is used to indicate allocated narrowband and PRBs allocated within the allocated narrowband; the number of allocated narrow bands indicated by the state of the bits in which the resource block allocation information exists is greater than 1, and the PRBs allocated in each of the allocated narrow bands are the same.

The resource block allocation information for indicating allocated narrowband includes:

Optionally, the resource block allocation information is used to indicate that the PRBs allocated within the allocated narrowband include:

Optionally, the prohibited resource includes one or more of the following first prohibited resource, second prohibited resource, third prohibited resource, fourth prohibited resource, fifth prohibited resource, and sixth prohibited resource:

Referring to fig. 4, fig. 4 is a resource allocation method according to another embodiment of the present application, where the method is executed between a network device and a terminal, and the terminal may specifically be: smart mobile phone, panel computer, smart television, intelligent printer, intelligent insulating pot, smart electric meter equipment etc. this network equipment specifically can be: base station, smart phone, tablet, relay station, etc. The method takes 1/2 narrow bands, namely 3 PRBs, as resource units of resource allocation. And a resource allocation mode of combining the starting point with the length is adopted. The resource block allocation information of the present embodiment does not indicate the prohibited resource. As shown in fig. 4, the method comprises the following steps:

step S401, a network device sends resource block allocation information to a terminal, wherein the resource block allocation information is used for indicating the number of initial resource units and continuous resource units allocated by the network device, and the resource units are 1/2 narrow bands; the resource allocated to the terminal by the network equipment indicated by the resource block allocation information is selected from optional resources by the network equipment, and the optional resources are resources from which selection prohibition resources are deleted from all resources.

For the resource block allocation information in this embodiment, the resource unit is 1/2 narrowband, and the RIV value corresponding to each binary bit string of the resource block allocation information is used to indicate a starting resource unit allocated by the network device and the number of consecutive resource units, where the starting resource unit is an 1/2 narrowband, and the RIV value represents a position of a starting 1/2 narrowband allocated and the number of consecutive 1/2 narrowbands allocated. The position of the start 1/2 narrowband of allocation may be 3 consecutive PRBs starting from the first PRB contained in the narrowband (PRB with PRB index 0 within the narrowband), i.e. the first 1/2 of one narrowband; the sequence may be 3 consecutive PRBs starting from the fourth PRB (PRB with PRB index of 3 in the narrowband), included in the narrowband, that is, the postamble 1/2 of one narrowband. Assuming that the number of the narrow bands included in the system bandwidth is N, 1/2 narrow band sharing 2N allocation methods are allocated, 1/2 × 2 is allocated, that is, 1 narrow band sharing 2N-1 allocation method (starting from a PRB whose PRB index in the narrow band is 3, 1 narrow band is allocated across the narrow bands, that is, 2 1/2 narrow bands are allocated and located in 2 consecutive narrow bands, respectively, or one narrow band among N narrow bands is allocated), 3/2 narrow band sharing 2N-2 allocation methods are allocated, … … N-1/2 narrow band sharing 2 allocation methods are allocated, and N narrow band sharing 1 allocation methods are allocated. Therefore, 1/2 narrow bands are taken as resource units, the position of the initial 1/2 narrow band of allocation and the number of the continuous 1/2 narrow bands of allocation are indicated to be 2N + (2N-1) + (2N-2) + … … +2+1 ═ 2N +1 × N allocation method in total, namely, (2N +1) × N allocation method is shared by all the resources in total.

Taking the 20MHz system bandwidth as an example, the number N of narrow bands included in the system bandwidth is 16, and all the resources have 528 allocation methods in total. If the resource allocated to the terminal by the network device indicated by the resource block allocation information is all the resources, it indicates that the 528 allocation method requires 10 bits. However, the total of the 10 bits is 1024 value states, wherein only 528 value states indicate resource allocation, so that more unused value states exist, bits of resource block allocation information are not effectively utilized, and bit overhead of the resource block allocation information is large. Therefore, in this embodiment, the resource allocated to the terminal by the network device indicated by the resource block allocation information is selected from selectable resources by the network device, where the selectable resource is a resource from which the selection of resources is prohibited is deleted from all resources. Still taking 20MHz system bandwidth as an example, if there are 16 allocation methods for the prohibited resources, the selectable resource is 512 allocation methods left after 16 types of resource blocks are deleted from 528 allocation methods, and the resource block allocation information needs 9 bits, that is, the 512 allocation methods for the selectable resource can be indicated, thereby saving bit overhead of the resource block allocation information.

The selectable resource or the prohibited resource needs to be set in a network device and a terminal in a prescribed manner. The predefined manner may be a protocol specification. The selection prohibiting resource may specifically be: p consecutive resource units starting from the first starting resource unit. I.e., P1/2 consecutive ribbons starting from the first 1/2 ribbon.

Optionally, the first starting resource unit includes the first 1/2 narrowbands of each narrowband and P is equal to 1. I.e. the forbidden resource is the allocation of 1/2 narrowbands, and the starting position is the first PRB contained in the narrowband, i.e. the first 1/2 narrowbands to allocate each narrowband. There are N total resource allocation methods. Taking 20MHz system bandwidth as an example, the first 1/2 narrow bands of each of the 16 narrow bands are forbidden resources, and there are 16 allocation methods in total.

Alternatively, the first starting resource unit includes the last 1/2 narrowbands of each narrowband and P is equal to 1. I.e. the forbidden resource is 1/2 narrowbands allocated, and the starting position is the fourth PRB contained in the narrowband, i.e. the last 1/2 narrowbands to allocate each narrowband. There are N total resource allocation methods. Taking 20MHz system bandwidth as an example, the last 1/2 narrow bands of each of the 16 narrow bands are forbidden resources, and there are 16 allocation methods in total.

Alternatively, the first starting resource unit includes the last 1/2 narrowbands of each narrowband, and P is equal to 2. That is, 1 narrowband is allocated, the starting position is the fourth PRB contained in the narrowband, that is, 1 narrowband is allocated across the narrowband, and there are N-1 resource allocation methods. And the first starting resource unit further includes the first 1/2 narrowbands whose narrowband index is a narrowband of N/2-1, the P being equal to 4. Where N represents the number of narrow bands contained in the system bandwidth, and N is an even number. I.e. 2 narrow bands in the middle of the system bandwidth are allocated, there is 1 allocation method. And the forbidden resources total N distribution method. Taking 20MHz system bandwidth as an example, the forbidden resource total has 16 allocation methods.

Optionally, the system bandwidth for the communication between the network device and the terminal includes: 1.4MHz, 3MHz, 5MHz, 10MHz, 20 MHz. I.e. when the system bandwidth is one or more of 1.4MHz, 3MHz, 5MHz, 10MHz, 20MHz, the de-selection resource is present. In this case, the resource block allocation information is

And (4) a bit. And when the system bandwidth of the communication between the network equipment and the terminal is other system bandwidth, the forbidden resource does not exist. I.e. the alternative resources are all resources. In this case, the resource block allocation information is

And (4) a bit. For example, when the system bandwidth of the communication between the network device and the terminal is 15MHz, the forbidden resource does not exist.

As shown in table 1, the number of allocation methods for resource allocation and the bit number of resource block allocation information in the embodiment of the present application are shown in an exemplary table.

Table 1:

and step S402, the terminal determines the first resource allocated by the network equipment according to the resource block allocation information.

Step S403, the terminal sends information to the network device or receives information sent by the network device in the first resource.

The embodiment of the application can allocate resources in a narrow band and resources with larger bandwidth, improves the flexibility of resource indication, and meets the requirement of the UE supporting larger service data bandwidth (larger than 1.4 MHz). The technical scheme provided by the embodiment allocates all resources into selectable resources and non-selectable resources, and limits the selection of allocated resources from the selectable resources, so that the allocation of resources is realized, the bit overhead of resource block allocation information is saved, effective significance is fully given to various values of resource block allocation information bits, and the resource block allocation information bits are effectively utilized.

Referring to fig. 5, fig. 5 is a resource allocation method according to another embodiment of the present application, where the method is executed between a network device and a terminal, and the terminal may specifically be: smart mobile phone, panel computer, smart television, intelligent printer, intelligent insulating pot, smart electric meter equipment etc. this network equipment specifically can be: base station, smart phone, tablet, relay station, etc. The method uses narrow band, namely 6 PRBs as resource units of resource allocation. And a resource allocation mode of combining the starting point with the length is adopted. The resource block allocation information of the present embodiment does not indicate the prohibited resource. As shown in fig. 5, the method comprises the following steps:

step S501, a network device sends resource block allocation information to a terminal, wherein the resource block allocation information is used for indicating the number of initial resource units and continuous resource units allocated by the network device, and the resource units are narrow bands; the resource allocated to the terminal by the network equipment indicated by the resource block allocation information is selected from optional resources by the network equipment, and the optional resources are resources from which selection prohibition resources are deleted from all resources.

For the resource block allocation information in this embodiment, the resource unit is a narrowband, and an RIV value corresponding to each binary bit string of the resource block allocation information indicates the number of the allocated starting resource unit and the number of consecutive resource units. The number of narrow bands contained in the system bandwidth is set as N, 1 narrow band sharing N distribution method is distributed, 2 narrow band sharing N-1 distribution methods are distributed, … … the N-1 narrow band sharing 2 distribution methods are distributed, and the N narrow band sharing 1 distribution method is distributed. Therefore, the total number of allocated starting narrow bands and allocated continuous narrow bands is indicated to be N + (N-1) + (N-2) + … … +2+1 ═ N +1) × N/2 allocation method by taking 1 narrow band as a resource unit, i.e. the total number of all resources is (N +1) × N/2 allocation method.

Taking 20MHz system bandwidth as an example, the number N of narrow bands included in the system bandwidth is 16, and all the resources have a total allocation method of 136. And if the resources allocated to the terminal by the network equipment indicated by the resource block allocation information are all resources, indicating that the 136 allocation method needs 8 bits. However, there are 256 value states in total for 8 bits, and only 136 value states indicate resource allocation, so that there are many unused value states, bits of resource block allocation information are not effectively utilized, and bit overhead of the resource block allocation information is large. Therefore, in this embodiment, the resource allocated to the terminal by the network device indicated by the resource block allocation information is selected from selectable resources by the network device, where the selectable resource is a resource from which the selection of resources is prohibited is deleted from all resources. Still taking 20MHz system bandwidth as an example, if there are 8 allocation methods for the prohibited resource, the selectable resource is a 128 allocation method left after 8 kinds of the prohibited resource are deleted from 136 allocation methods, and the resource block allocation information needs 7 bits, that is, the 128 allocation method for the selectable resource can be indicated, thereby saving the bit overhead of the resource block allocation information.

The selectable resource or the prohibited resource needs to be set in a network device and a terminal in a prescribed manner. The predefined manner may be a protocol specification. The selection prohibiting resource may specifically be: p consecutive resource units starting from the first starting resource unit. I.e. P consecutive narrow bands starting from the first narrow band.

Optionally, the first starting resource unit includes a narrowband whose narrowband index is an even number and P is equal to 1. That is, the reselected resource is a narrowband whose index is an even number and 1 narrowband is allocated. There are N/2 resource allocation methods in total. Taking 20MHz system bandwidth as an example, namely, all the narrow bands with even indexes in 16 narrow bands are forbidden resources, and there are 8 allocation methods in total.

Alternatively, the first starting resource unit includes a narrowband whose narrowband index is an odd number and P is equal to 1. That is, the reselected resource is a narrowband to which 1 narrowband is allocated, and the allocated narrowband is a narrowband whose index is odd. There are N/2 resource allocation methods in total. Taking 20MHz system bandwidth as an example, namely, all the narrow bands with odd indexes in 16 narrow bands are forbidden resources, and there are 8 allocation methods in total.

Alternatively, the first starting resource unit includes all the narrow bands in the system bandwidth and P is equal to 1. I.e. the prohibited resource is any narrow band in the bandwidth of the allocation system. There are N total resource allocation methods.

Optionally, the system bandwidth for the communication between the network device and the terminal includes: 3MHz, 5MHz, 10MHz and 20 MHz. I.e. when the system bandwidth is one or more of 3MHz, 5MHz, 10MHz, 20MHz, the de-selection resource is present. In this case, the resource block allocation information is

One bit (forbidden resource allocation method is N/2) or

And (N) bits (the forbidden resource allocation method is N). And when the system bandwidth of the communication between the network equipment and the terminal is other system bandwidth, the forbidden resource is not stored. I.e. the alternative resources are all resources. In this case, the resource block allocation information is

As shown in table 2, a bit number indication table of resource allocation method number and resource block allocation information in the embodiment of the present application is shown.

Table 2:

for example, for a 20MHz system bandwidth, the number of bits of the resource block allocation information is 7, and the bits of the resource block allocation information are b6b5b4b3b2b1b 0. The 8 states of the bit b2b1b0 are used to indicate that 1 narrowband is allocated and only odd or even indexed narrowband can be allocated. b6b5b4b3b2b1b0, for indicating resource allocations of more than one narrowband. Each value of RIV corresponds to the location of a starting narrowband and the number of consecutive narrowbands allocated.

Step S502, the terminal determines the first resource allocated by the network equipment according to the resource block allocation information.

Step S503, the terminal sends information to the network device or receives information sent by the network device in the first resource.

The embodiment of the present application further provides a resource allocation method, and the embodiment is used for supporting a UE whose PDSCH or PUSCH bandwidth is 5 MHz. The method takes PRB as a resource unit of resource allocation. And a resource allocation mode of combining the starting point with the length is adopted. The resource block allocation information of the present embodiment does not indicate the prohibited resource.

In this embodiment, the resource block allocation information is used to indicate a starting resource unit allocated by the network device and the number of consecutive resource units, where the resource unit is a PRB; the resource allocated to the terminal by the network equipment indicated by the resource block allocation information is selected from optional resources by the network equipment, and the optional resources are resources from which selection prohibition resources are deleted from all resources.

In the existing LTE system, for downlink resource allocation, a resource allocation manner of a starting point combined with a length takes PRB as granularity and is a Type 2 resource allocation manner; for uplink resource allocation, the resource allocation mode of the starting point combined with the length takes the PRB as the granularity and is a Type 0 resource allocation mode. The embodiment is similar to the Type 2 or Type 0 resource allocation manner in the existing LTE system. And the RIV value corresponding to each binary bit string of the resource block allocation information represents the number of the starting PRB for allocating resources and the number of the PRBs for allocating continuously.

In this embodiment, the starting PRB is any PRB in the system bandwidth, and the number of allocated continuous PRBs is one of 1 to the number of PRBs in the system bandwidth. The forbidden resource is P consecutive resource units starting from the first starting resource unit.

In one particular approach, the embodiment allocates a maximum of 24 PRBs. This embodiment is applied to resource allocation of PDSCH or PUSCH.

Optionally, when a system bandwidth of communication between the network device and the terminal is 10MHz, 15MHz, and 20MHz, the first starting resource unit includes all PRBs in the system bandwidth, and P is greater than 24. Optionally, when the system bandwidth in which the network device and the terminal communicate is 20MHz, the first starting resource unit further includes PRBs whose PRB index within the system bandwidth is odd or even and P is equal to 1, and the first starting resource unit further includes PRBs whose PRB index within the system bandwidth is X and P is equal to 2; wherein X takes 26 different values of [0,99 ].

Optionally, when a system bandwidth of communication between the network device and the terminal is 20MHz, the first starting resource unit includes all PRBs in the system bandwidth and P is greater than 23; when the system bandwidth of the communication between the network device and the terminal is 10MHz or 15MHz, the first starting resource unit includes all PRBs in the system bandwidth and P is greater than 24.

The number of allocation methods for resource allocation and the number of bits of resource block allocation information in a specific embodiment of this embodiment are shown in table 3 below.

Table 3:

in another specific way, the embodiment allocates a maximum of 25 PRBs. This embodiment is applied to resource allocation of PUSCH.

Optionally, when a system bandwidth of communication between the network device and the terminal is 10MHz, 15MHz, and 20MHz, the first starting resource unit includes all PRBs in the system bandwidth, and P is greater than 25. Optionally, when a system bandwidth in which the network device and the terminal communicate is 20MHz, the first starting resource unit further includes all PRBs in the system bandwidth and P is equal to 1, and the first starting resource unit further includes PRBs whose PRB index within the system bandwidth is Y and P is equal to 2; where Y takes 52 different values within [0,99 ].

Optionally, when a system bandwidth of communication between the network device and the terminal is 20MHz, the first starting resource unit includes all PRBs in the system bandwidth and P is greater than 23; when the system bandwidth is 10MHz or 15MHz, the first starting resource unit includes all PRBs in the system bandwidth and P is greater than 25.

The number of allocation methods for resource allocation and the number of bits of resource block allocation information in another specific embodiment of this embodiment are shown in table 4 below.

Table 4:

An embodiment of the present application further provides a resource allocation method, and the embodiment is used for supporting a UE whose PDSCH or PUSCH bandwidth is 5 MHz. In this embodiment, the resource block allocation information is used to indicate the allocated narrowband and the allocated PRBs within the allocated narrowband; the number of allocated narrow bands indicated by the state of the bits in which the resource block allocation information exists is greater than 1, and the PRBs allocated in each of the allocated narrow bands are the same. The resource block allocation information of the present embodiment does not indicate the prohibited resource. That is, the resource allocated to the terminal by the network device indicated by the resource block allocation information is selected from selectable resources by the network device, and the selectable resource is a resource from which the selection of the resource is prohibited, among all resources.

The specific way that the resource block allocation information is used for indicating the allocated narrowband is that the resource block allocation information is used for indicating a starting narrowband index and whether resources are allocated to each narrowband of 3 consecutive narrowbands after the starting narrowband. If the starting narrowband index is i, the continuous 3 narrowbands after the starting narrowband index means that the narrowband index is 3 narrowbands of i +1, i +2 and i + 3.

The system bandwidth comprises N narrow bands, and the indexes are 0-N-1 respectively. In this embodiment, the starting narrowband index may be N.

There are 8 possible kinds indicating whether each of consecutive 3 narrowband after the starting narrowband allocates resources. The narrowband allocation resource is initiated by default. The specific approach applies to e.g. PDSCH.

The specific mode that the resource block allocation information is used for indicating the allocated narrow bands is that the resource block allocation information is used for indicating the initial narrow band index and the number of the allocated narrow bands. 1-4 narrow bands can be distributed. The allocated narrowband is a continuous narrowband starting from the narrowband indicated by the starting narrowband index. The second embodiment is applied to, for example, PUSCH.

The third specific way that the resource block allocation information is used for indicating the allocated narrowband is that the resource block allocation information is used for indicating a starting narrowband index and a starting point and the number of allocated narrowband in 4 consecutive narrowband starting from the starting narrowband. That is, in 4 consecutive narrow bands starting from the starting narrow band, the starting point is used to combine with the length indication, and the narrow band is used as the granularity. There are 10 possibilities, 4+3+2+ 1. If the starting narrowband index is i, the 4 consecutive narrowband indexes from the starting narrowband refer to 4 narrowband indexes i, i +1, i +2, i + 3.

The above three specific ways of using the resource block allocation information to indicate allocated narrowband can be applied to any system bandwidth. In particular, the above three specific ways of using the resource block allocation information to indicate allocated narrow bands are applied to the system bandwidth > 5 MHz.

When the system bandwidth of the communication between the network device and the terminal is 5MHz or 3MHz, the specific manner in which the resource block allocation information is used to indicate allocated narrow bands is that the resource block allocation information is used to indicate whether each narrow band in the system bandwidth is allocated. There are 16 possibilities for a 5MHz system bandwidth; there are 4 possibilities for a 3MHz system bandwidth.

And when the system bandwidth of the communication between the network equipment and the terminal is 5MHz or 3MHz, the concrete mode that the resource block allocation information is used for indicating the allocated narrow bands is that the resource block allocation information is used for indicating the number of the allocated narrow bands. Indicating the allocated narrowband starts with a narrowband whose index is 0. There are 4 possibilities for a 5MHz system bandwidth. There are 2 possibilities for a 3MHz system bandwidth.

When the system bandwidth of the communication between the network device and the terminal is 5MHz or 3MHz, a sixth specific way that the resource block allocation information is used for indicating allocated narrow bands is that the resource block allocation information is used for indicating allocated narrow band starting points and the number of the allocated narrow bands. Namely, the narrowband of the allocation is indicated by adopting an indication mode of combining the starting point with the length, and the narrowband is taken as the granularity. There are 10 possibilities for a 5MHz system bandwidth. There are 3 possibilities for a 3MHz system bandwidth.

It should be noted that, in the specific manner in which the resource block allocation information is used to indicate the allocated narrowband, the listed possibilities are the possibilities of all resource allocation methods, and the allocation method of the prohibited resource is not deleted.

The specific way that the resource block allocation information is used for indicating the PRBs allocated within the allocated narrowband is that the resource block allocation information is used for indicating the starting PRBs and the number of PRBs allocated within the narrowband. Namely, a resource allocation method of a starting point combination length is adopted, and PRB is used as a resource unit. Similar to the resource allocation in the existing DCI format 6-0A or 6-1A narrow band, all the resource allocation methods have 21 kinds. The resource allocation method in each of the starting narrowband and consecutive 3 narrowbands following the starting narrowband is the same.

The specific way that the resource block allocation information is used for indicating the PRBs allocated within the allocated narrowband is that when the allocated narrowband number M indicated by the resource block allocation information is 1, the resource block allocation information is used for indicating the starting PRB and PRB number allocated within the narrowband. I.e. using a narrowband intra resource allocation similar to the existing DCI format 6-0A or 6-1A starting point combination length. When the number M of allocated narrow bands indicated by the resource block allocation information is greater than 1, the resource block allocation information is used to indicate the number of PRBs allocated within the narrow band with the largest or smallest index among the allocated narrow bands, and all PRBs within the remaining M-1 narrow bands are allocated. The PRBs allocated in one of the narrowband with the largest or smallest index and the PRBs allocated in the remaining narrowband constitute consecutive PRBs. The resource block allocation information is used to indicate that the specific way second that the PRBs are allocated within the allocated narrowband applies to, for example, the PUSCH. The second embodiment ensures that the allocated resources are contiguous.

In this embodiment, the resource block allocation information is used to indicate allocated narrowbands, and the PRBs allocated within the allocated narrowbands may be respectively indicated by different binary bit strings. The allocated narrowband and the PRBs allocated within the allocated narrowband may also be represented by an RIV value corresponding to a binary bit string.

The forbidden resources comprise one or more of the following first forbidden resources, second forbidden resources, third forbidden resources, fourth forbidden resources, fifth forbidden resources and sixth forbidden resources:

the first forbidden resource comprises that when the system bandwidth of the communication between the network equipment and the terminal is more than or equal to 5MHz, the starting narrow-band index is one of the maximum value, the second large value or the third large value of all narrow-band indexes.

The second forbidden resource comprises the number of the allocated PRBs in the narrowband is 1.

The third forbidden resource comprises 1 and 2 PRBs allocated in the narrowband.

The fourth forbidden resource comprises the PRBs distributed in the narrowband are 1 and 2, the starting PRB distributed in the narrowband is the PRB with the index S, and the number of the PRBs is 3; where S is the PRB index within the narrowband, S takes 2 different values within [0,3 ]. In particular, S takes 1 and 2.

When the fifth forbidden resource comprises that the system bandwidth of the communication between the network equipment and the terminal is more than 5MHz, the starting narrow-band index is a natural number less than or equal to N-4, and the number of PRBs (physical resource blocks) distributed in a narrow band is 1 and 2; the starting narrowband index is N-4, the starting PRB distributed in the narrowband is the PRB of the index S, and the number of the PRBs is 3; and the starting narrowband index is one of N-3, N-2, N-1; where S is the PRB index within the narrowband, S takes 2 different values within [0,3], and N is the number of narrowbands included in the system bandwidth. In particular, S takes 1 and 2.

Table 5 illustrates the number of possible resource allocation methods and the number of bits used by the resource block allocation information when the system bandwidth is greater than 5MHz, where the specific manner one indicates the allocated narrowband and the specific manner one indicates PRBs allocated within the allocated narrowband, and the prohibited resources include the fourth (fifth) prohibited resource.

When the system bandwidth is 5MHz or 3MHz, indicating the allocated narrowband adopts a specific mode six, indicating the allocated PRB adopts a specific mode two within the allocated narrowband, and the number of possible resource allocation methods and the number of bits used by the resource block allocation information are also shown in the following table.
