Description

Resource allocation method, device and equipment

Technical Field

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

Background

With the development of Communication technology, the application of Long Term Evolution (LTE) system is becoming more and more widespread, and one application thereof is for MTC (Machine Type Communication). In the LTE system, data in a Physical channel may be transmitted through a PRB (Physical Resource Block), where the PRB corresponds to 12 continuous subcarriers in a frequency domain and corresponds to one slot (i.e., a half subframe) in a time domain. Wherein, a narrowband contains the frequency width of 6 PRBs in the frequency domain. In Rel-13 version of LTE, a terminal device capable of supporting MTC service is a BL UE (Bandwidth-reduced Low-complexity User Equipment) or a CE UE (Coverage Enhancement User Equipment), and its maximum supportable transmission and reception Bandwidth is 1.4MHz, that is, it can only receive and transmit data within one narrow band. The Rel-13 version of LTE provides CE UEs with two Coverage Enhancement modes, namely CE mode a for smaller Coverage Enhancement degrees and CE mode B for larger Coverage Enhancement degrees.

Before data transmission is performed between the network device and the terminal device, the network device allocates physical resources for data transmission to the terminal device. The physical resources include one or more PRBs. The network device may first determine a narrowband (which may be referred to as a target narrowband for convenience of description) for data transmission of the terminal device, and then select a PRB allocated for the terminal device among 6 PRBs included in the target narrowband. The network device may determine index information for the target narrowband and may determine allocation information for PRBs within the narrowband based on the PRBs selected from the target narrowband. The allocation information of the PRBs in the narrowband may be 3 bits. For example, with 0-5 identifying 6 PRBs in a narrowband, the bit state 000 of allocation information for PRBs within the narrowband corresponds to 0, 001 corresponds to 1,010 corresponds to 2.. 110 corresponds to 0 and 1,111 corresponds to 2 and 3, and if the PRBs allocated by the network device for the terminal device are 0 and 1, then the state of the bits of allocation information for PRBs within the narrowband can be determined to be 110. The network device may send resource allocation information to the terminal device, where the resource allocation information may include the determined index information and allocation information of PRBs in the narrowband. The terminal device also stores the resource allocation rule, then determines the corresponding PRB according to the bit state of the resource allocation information, and performs data transmission based on the determined PRB.

In order to enable MTC to support higher data rates, in Rel-14 release of LTE, the bandwidth for transmitting data that can be supported by a terminal device performing MTC services is extended. In CE mode B, the PUSCH (Physical Uplink Shared channel) Bandwidth supported by BL UE and non-BL UE (non-Bandwidth-reduced Low-complexity UE) still maintains 1.4 MHz. However, for PDSCH (Physical Downlink Shared channel), the maximum data bandwidth supported by the BL UE is extended to 5MHz, and the data bandwidth of PDSCH supported by the non-BL UE may be 1.4MHz, 5MHz or 20 MHz. In addition, in the LTE system, the system bandwidth supported by the network device may also be various, such as 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz, 20MHz, and the like.

In the course of implementing the present disclosure, the inventors found that the prior art has at least the following problems:

when physical resources are allocated, the network device can only allocate physical resources to the terminal device within one narrow band, and data can only be transmitted between the terminal device and the network device on the physical resources within one narrow band, so that the efficiency of data transmission is low, and the requirement of the terminal device for performing MTC services on higher data rate cannot be met.

To make the objects, technical solutions and advantages of the present disclosure more apparent, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

In practice, the network device and the terminal device may transmit data through a communication system (such as an LTE system or an evolved system thereof). In a communication system, data in a physical channel may be transmitted through a PRB, which corresponds to 12 consecutive subcarriers in the frequency domain and one slot (i.e., a half subframe) in the time domain. Wherein, one narrowband contains 6 PRBs in the frequency domain. 4 consecutive narrow bands can constitute a wide band. For example, a 20MHz system bandwidth may include 100 PRBs, 96 PRBs of which may constitute 16 narrow bands, and 16 narrow bands may constitute 4 wide bands, that is, 16 narrow bands or 4 wide bands in the 20MHz system bandwidth. The physical resources include one or more PRBs.

Before transmitting data, the network device needs to allocate a physical resource to the terminal device, so that the network device and the terminal device can transmit data on the physical resource.

In order to meet the requirement of a terminal device performing MTC service on higher data rate, this embodiment provides a method for resource allocation, which may be executed by a network device, as shown in fig. 4, where a processing flow of the method may be as follows:

step 401, the network device sends resource allocation information to the terminal device.

In an implementation, a PRB index, a narrowband index, and a wideband index may be set. The PRBs within the system bandwidth of the network device may be numbered in ascending (or descending) frequency order, and the number of each PRB is the PRB index of the PRB. PRB indexed by n is PRB_n. The narrow bands within the system bandwidth may also be numbered in ascending (or descending) frequency order, and the number of each narrow band is a narrow band index of the narrow band. The narrowband indexed i is NB_i。NB_iMay contain physical resource blocks, PRBs, in frequency_n,PRB_n+1，PRB_n+2，PRB_n+3，PRB_n+4，PRB_n+5Wherein PRB_nIs a narrowband NB_iThe PRB with the smallest middle index value is also called the first PRB. The wideband in the system bandwidth may also be numbered in ascending (or descending) frequency order, and the number of each wideband is the wideband index of the wideband. Wideband WB with index j_j。WB_jMay contain a narrow band NB in frequency_i，NB_i+1，NB_i+2，NB_i+3Wherein NB is_iFor wideband WB_jThe narrow band with the smallest index value. For example, for a 20MHz system bandwidth, the narrowband index is 0-15, the PRB index is 0-99, and the wideband index is 0-3. Wherein n, i and j are all nonnegative integers.

When the index indication information may indicate the allocated starting narrowband, specific implementations may include the following.

(1) The index indication information may be used to indicate a narrowband index, where the narrowband index is a multiple of X, X is one of 4, 2, and 1, and the starting narrowband is a narrowband represented by the narrowband index.

In an implementation, the bit state of the index indication information may indicate a narrowband index. For example, for a 20MHz system bandwidth, a value of X is 4, and a narrowband index that the index indication information needs to indicate is one of 0, 4, 8, and 12, the index indication information may be 2 bits, and include 4 different bit states, which respectively indicate 0, 4, 8, and 12, and at this time, the starting narrowband may be NB_iAnd i is one of 0, 4, 8 and 12. Similarly, if X takes a value of 2, the index indication information may be 3 bits for indicating that the narrowband index is one of 0, 2, 4, 6, 8, 10, 12, and 14, and the starting narrowband may be NB_iAnd i is one of 0, 2, 4, 6, 8, 10, 12 and 14.

(2) The index indication information is used for indicating the physical resource block PRB index, the index of the narrow band where the PRB is located is a multiple of X, the value of X is one of 4, 2 and 1, and the starting narrow band is the narrow band where the PRB represented by the PRB index is located.

In an implementation, the bit state of the index indication information may indicate a PRB index. For example, for a 10MHz system bandwidth, the value of X is 4, the index of a narrow band in the system bandwidth is 0 to 7, the PRB index that the index indication information needs to indicate is one of 1 and 25, the index indication information is 1 bit, includes 2 different bit states, and indicates one of 1 and 25 respectively, at this time, the starting narrow band may be an NB_iAnd i is one of 0 and 4.

(3) The index indication information is used to indicate a wideband index, and the starting narrowband is the narrowband with the smallest index value among the narrowbands included in the wideband represented by the wideband index.

In an implementation, the bit state of the index indication information may indicate a wideband index. For example, for a 20MHz system bandwidth, the index indication information needs to indicate one of

wideband indexes

0, 1,2, and 3, the index indication information is 2 bits, and includes 4 different bit states, each indicating one of 0, 1,2, and 3, and at this time, the starting narrowband may be NB_iAnd i is 0 and one of 4, 8 or 12.

The index indication information may be

A number of bits, wherein,

may represent the number of PRBs that the system bandwidth contains in frequency. For example, if the system bandwidth is 20MHz and X is 4, the index indication information may be 2 bits; the system bandwidth is 10MHz, and X is 4, the index indication information may be 1 bit. The bit number of the index indication information corresponding to each value of X under different system bandwidths can be seen in table 8.

The following explains the narrowband allocation information.

In an implementation, the narrowband allocation information may be 2 bits or 3 bits, and a bit state of the narrowband allocation information may be used to indicate whether the allocated physical resource is within 1 narrowband or greater than 1 narrowband. When resource allocation within 1 narrowband is indicated, the narrowband may be the starting narrowband. When resource allocation of more than 1 narrowband is indicated, the narrowband allocation information may indicate resource allocation within G consecutive narrowbands starting from the starting narrowband, G may be a positive integer and not more than 4 or 16.

When the narrowband allocation information indicates resource allocation in more than one narrowband, there may be several cases:

(1) the number of bits of the narrowband allocation information may be 3, and the physical resources allocated by the narrowband allocation information may include (NB)_i,NB_i+1)、(NB_i,NB_i+2)、(NB_i,NB_i+3)、(NB_i+1,NB_i+2)、(NB_i+1,NB_i+3)、(NB_i+2,NB_i+3)、(NB_i,NB_i+1,NB_i+2)、(NB_i+1,NB_i+2,NB_i+3)、(NB_i,NB_i+1,NB_i+3)、(NB_i,NB_i+2,NB_i+3)、(NB_i,NB_i+1,NB_i+2,NB_i+3) One or more of (a).

Wherein, NB_iIs an initial narrow band; NB_i、NB_i+1、NB_i+2And NB_i+3There may be 4 narrow bands in succession.

This case may be applicable to a scenario where the system bandwidth is greater than 3MHz, the data bandwidth of the terminal device is equal to 5MHz, and the 3-bit indication indicates that the allocated physical resource is 4 narrow bands at most, i.e. 24 PRBs or one wide band. In this case, the number of resource blocks allocated in the bit state of the resource allocation information is equal to or less than 24. G is not more than 4.

(2) The bit number of the narrowband allocation information is 3, and the physical resource allocated by the narrowband allocation information comprises WB_j、(WB_j,WB_j+1)、(WB_j+1,WB_j+2)、(WB_j+2,WB_j+3)、(WB_j,WB_j+1,WB_j+2)、(WB_j+1,WB_j+2,WB_j+3)、(WB_j,WB_j+1,WB_j+2,WB_j+3) One or more of (a). Or, the physical resource allocated by the narrow-band allocation information comprises WB_j、(WB_j,WB_j+1)、(WB_j,WB_j+2)、(WB_j,WB_j+3)、(WB_j,WB_j+1,WB_j+2)、(WB_j,WB_j+1,WB_j+3)、(WB_j,WB_j+2,WB_j+3)、(WB_j,WB_j+1,WB_j+2,WB_j+3) One or more of (a).

Among them, WB_jRepresenting by narrowband NB_i、NB_i+1、NB_i+2、NB_i+3A broadband of compositions; WB (wideband weight division multiple Access)_j+1Representing by narrowband NB_i+4、NB_i+5、NB_i+6、NB_i+7A broadband of compositions; WB (wideband weight division multiple Access)_j+2Representing by narrowband NB_i+8、NB_i+9、NB_i+10、NB_i+11A broadband of compositions; WB (wideband weight division multiple Access)_j+3Representing by narrowband NB_i+12、NB_i+13、NB_i+14、NB_i+15A broadband of compositions; NB_iIs an initial narrow band; narrow band NB_i～NB_i+15Is a continuous narrow band; WB (wideband weight division multiple Access)_j,WB_j+1,WB_j+2,WB_j+3Is a continuous broadband.

This case may be applicable to a scenario where the system bandwidth is 20MHz, the data bandwidth of the terminal device is equal to 20MHz, and the 3-bit indication indicates that the allocated physical resources are 16 narrow bands at most, i.e. 96 PRBs or 4 wide bands. In this case, the number of resource blocks allocated in the bit state of the resource allocation information is not more than 96. G is not more than 16.

(3) The bit number of the narrowband allocation information is 2, and the physical resource allocated by the narrowband allocation information includes (NB)_i,NB_i+1)。

Wherein, NB_iIs an initial narrow band; NB_i、NB_i+1Is a continuous 2 narrow bands.

This case may be applicable to a scenario where the system bandwidth is 3MHz, and the 2-bit indication indicates that the allocated physical resources are at most 2 narrow bands.

In the above cases, the physical resource allocated by the narrowband allocation information may further include (PRB)_n,PRB_n+1，PRB_n+2，PRB_n+3) And/or NB_i. Wherein, NB_iTo initiate narrowband, (PRB)_n,PRB_n+1，PRB_n+2，PRB_n+3) Is NB_iThe index of the contained PRBs is the smallest 4 PRBs. In this way, the narrowband allocation Information may also indicate allocation of 4 PRBs within the narrowband and allocation of physical resources of the entire narrowband, which is compatible with resource allocation of DCI (Downlink Control Information) format 6-1B of Rel-13 version of LTE. Thus, when the allocated physical resources are physical resources of a group of terminal devices, for example, resources of Random Access Response (RAR) are allocated, the same physical resources can be allocated to UEs supporting a larger data bandwidth (greater than 1.4MHz) and UEs supporting a 1.4MHz data bandwidth, so that multiple sets of resources are prevented from being transmitted to UEs with different bandwidth capabilities, and the efficiency of resource utilization is improved.

The present embodiment provides examples of narrowband allocation information indicating resource allocation under several different scenarios, which are described in detail below.

For the above case (1), the narrowband of the narrowband allocation information allocation may be continuous, as shown in table 1:

TABLE 1

In table 1, the first two bit states may indicate whether the allocated physical resources are within the narrowband, indicating whether 4 PRBs are allocated or the entire narrowband (i.e., 6 PRBs) is allocated, respectively. The latter 6 states indicate that the allocated physical resources are greater than 1 narrowband. It may be indicated that consecutive 2,3 or 4 narrow bands are allocated. The resource allocation indication of table 2 may indicate that resources of 4 narrow bands, i.e., 24 PRBs or one wide band, are allocated at most. The resource allocation indication of table 2 may indicate that 4 PRBs are allocated, 1 narrowband physical resource is allocated, and thus may be compatible with resource allocation of DCI format 6-1B of Rel-13 version of LTE.

For the above case (1), the narrowband of the narrowband allocation information allocation may be continuous or discontinuous, as shown in table 2:

TABLE 2

In table 2, the first two bit states may indicate whether the allocated physical resources are within the narrowband, indicating whether 4 PRBs are allocated or the entire narrowband (i.e., 6 PRBs) is allocated, respectively. The latter 6 states indicate that the allocated resources are greater than 1 narrowband. It may indicate that 2,3 or 4 narrow bands are allocated. When the indication is allocated with 2,3 narrow bands, the narrow bands may be continuous or discontinuous. The resource allocation indication of table 2 may indicate that physical resources of 4 narrow bands, i.e., 24 PRBs or one wide band, are allocated at most. The resource allocation indication of table 2 may indicate that 4 PRBs are allocated, 1 narrowband physical resource is allocated, and thus may be compatible with resource allocation of DCI format 6-1B of Rel-13 version of LTE.

For the above case (2), the narrowband of the narrowband allocation information allocation may be continuous. The physical resources allocated by the narrow-band allocation information comprise WB_j、(WB_j,WB_j+1)、(WB_j+1,WB_j+2)、(WB_j+2,WB_j+3)、(WB_j,WB_j+1,WB_j+2)、(WB_j+1,WB_j+2,WB_j+3)、(WB_j,WB_j+1,WB_j+2,WB_j+3) One or more of (a). For example, as shown in table 3:

TABLE 3

In Table 3, WB_jIs represented by NB_iOf 4 successive narrow bands, i.e. narrow bands NB, for the starting narrow band_i、NB_i+1、NB_i+2、NB_i+3；WB_j+1Is represented by NB_i+4Of 4 successive narrow bands, i.e. narrow bands NB, for the starting narrow band_i+4、NB_i+5、NB_i+6、NB_i+7；WB_j+2Is represented by NB_i+8Of 4 successive narrow bands, i.e. narrow bands NB, for the starting narrow band_i+8、NB_i+9、NB_i+10、NB_i+11；WB_j+3Is represented by NB_i+12Of 4 successive narrow bands, i.e. narrow bands NB, for the starting narrow band_i+12、NB_i+13、NB_i+14、NB_i+15. When the 3-bit state is 000, it indicates that 4 PRBs are allocated or that physical resources of the entire narrowband are allocated. The resource allocation indication of table 3 may indicate allocation of physical resources of 16 narrow bands, i.e., 96 PRBs or 4 wide bands, at the maximum. The resource allocation of table 3 comprises allocation of 4 PRBs or 1 narrowband (6 PRBs), which is compatible with resource allocation of Rel-13.

The narrowband of the narrowband allocation information allocation may also be as shown in table 4.

TABLE 4

In table 4, when the 3-bit state is 000, it indicates that 4 PRBs are allocated or indicates that the physical resource of the entire narrowband is allocated; when the 3bit state is 001, it indicates that two consecutive narrow bands are allocated, wherein NB_iAnd NB_i+1May be WB_jThe two narrow bands with the minimum middle index value. The latter 6 states indicate that the allocated physical resources are greater than or equal to 1 bandwidth.

For the above case (2), the narrowband allocated by the narrowband allocation information may be continuous or discontinuous, and the physical resource allocated by the narrowband allocation information includes WB_j、(WB_j,WB_j+1)、(WB_j,WB_j+2)、(WB_j,WB_j+3)、(WB_j,WB_j+1,WB_j+2)、(WB_j,WB_j+1,WB_j+3)、(WB_j,WB_j+2,WB_j+3)、(WB_j,WB_j+1,WB_j+2,WB_j+3) One or more of (a). When 8 narrow bands are allocated, the resource allocation indicated by the state of the bit includes (WB)_j,WB_j+1)、(WB_j,WB_j+2)、(WB_j,WB_j+3) One or more of (a). When 12 narrow bands are allocated, the resource allocation of the 3-bit status indication includes (WB)_j,WB_j+1,WB_j+2)、(WB_j,WB_j+1,WB_j+3)、(WB_j,WB_j+2,WB_j+3) One or more of (a). The narrowband of the narrowband allocation information allocation may also be as shown in table 5 or table 6:

TABLE 5

TABLE 6

For the above case (3), the narrowband of the narrowband allocation information allocation may be as shown in table 7:

TABLE 7

In table 7, the narrowband allocation information may indicate that physical resources of 2 narrowbands, i.e., 12 PRBs, are allocated at most. The resource allocation of table 7 may be applied to a terminal device supporting a data bandwidth of 5MHz, and may also be applied to a terminal device supporting a data bandwidth of 20 MHz. The resource allocation indication of table 7 may indicate that 4 PRBs within a narrowband are allocated, the physical resources of the entire narrowband are allocated, and thus are compatible with the resource allocation of DCI format 6-1B of Rel-13 version of LTE.

In the first mode, the number of bits of the resource allocation information may be as shown in table 8:

TABLE 8

In the first embodiment, when the system bandwidth of a terminal device supporting 20MHz data bandwidth is less than 20MHz and greater than 3MHz, if the narrowband index indicated by a certain bit state in the bit states of the narrowband allocation information exceeds the maximum value of the narrowband index in the system bandwidth, the narrowband allocation information is invalid.

Or, for a terminal device supporting 20MHz of data bandwidth, when the system bandwidth is less than 20MHz and greater than 3MHz, if a narrowband index indicated by a certain bit state in the bit states of the narrowband allocation information exceeds the maximum value of the narrowband indexes in the system bandwidth, a narrowband indicated by an index value that does not exceed the maximum value of the narrowband indexes in the system bandwidth is valid in the narrowband indexes indicated by the narrowband allocation information.

Optionally, the value of X may be determined according to the system bandwidth of the network device. When the system bandwidth of the network device is the first system bandwidth, the narrowband index or the narrowband where the PRB is locatedThe index is X₁Multiples of (d); when the system bandwidth of the network device is the second system bandwidth, the index of the narrowband or the index of the narrowband where the PRB is located is X₂Multiples of (a).

Or, the value of X may be determined according to the data bandwidth supported by the terminal device. When the data bandwidth supported by the terminal device is the first data bandwidth, the index of the narrow band where the PRB is located or the index of the narrow band where the PRB is located is X₁Multiples of (d); when the data bandwidth supported by the terminal device is the second data bandwidth, the index of the narrow band where the PRB is located or the index of the narrow band where the PRB is located is X₂Multiples of (a).

Wherein the first system bandwidth is greater than the second system bandwidth; the first data bandwidth is greater than the second data bandwidth, X₁Greater than X₂，X₁、X₂The values of (A) are respectively one of 4, 2 and 1.

Based on the above processing, for a larger system bandwidth, a larger granularity allocation mode may be adopted; for smaller system bandwidth, a smaller granularity of allocation may be employed. Similarly, for larger data bandwidth, a larger granularity allocation mode can be adopted; for smaller data bandwidth, a smaller granularity of allocation may be employed. Therefore, the distribution granularity can be matched with the current system bandwidth or network bandwidth, and the reasonability of resource distribution is improved.

Based on the first method, the network device may first determine the starting narrowband allocated to the terminal device and G consecutive narrowbands starting from the starting narrowband, and then may determine the physical resource allocated to the terminal device from the G consecutive narrowbands. The network device may determine the index indication information according to a starting narrowband included in the physical resource allocated to the terminal device, may determine a bit state of the narrowband allocation information according to the physical resource allocated from the consecutive G narrowbands, and further obtains the bit state of the resource allocation information according to the determined index indication information and the narrowband allocation information.

And in the second mode, the bit number of the resource allocation information is less than or equal to 5, the bit number of the resource allocation information is the same as the number of the narrow band groups NBGs, each bit of the resource allocation information corresponds to one NBG, and two states of each bit indicate whether physical resources contained in the corresponding NBG are allocated or not.

In an implementation, the narrow bands within the system bandwidth may be grouped to obtain at least one Narrow Band Group (NBG). Wherein one NBG may contain at least one narrow band. In the second method, the resource allocation is performed by bit mapping with NBG as granularity. The number of bits of the resource allocation information may be the same as the number of the divided NBGs, and each NBG may be mapped to one bit, and two bit states of the bit may indicate whether the corresponding NBG is allocated. For example, bit state 0 may indicate that the corresponding NBG is not allocated and bit state 1 may indicate that the corresponding NBG is allocated. When a certain NBG is allocated, all PRBs in the NBG are allocated. In the second mode, any two NBGs contain a maximum difference of the number of narrow bands not exceeding 1.

The NBG may be divided according to the following scheme in table 9:

TABLE 9

The numbers corresponding to the NBG division examples indicate the number of narrow bands included in each NBG.

For example, for a 20MHz system bandwidth, 3,3,3,3,4 indicates that 5 NBGs are totally divided, each NBG in the first 4 NBGs includes 3 narrow bands, and the last NBG includes 4 narrow bands, that is, the index of the narrow band included in the first NBG is 0 to 2, the index of the narrow band included in the second NBG is 3 to 5, the index of the narrow band included in the third NBG is 6 to 8, the index of the narrow band included in the fourth NBG is 9 to 11, and the index of the narrow band included in the fifth NBG is 12 to 15;

for a 15MHz system bandwidth, 2,2,2,3,3 denote that 5 NBGs are divided in total, each NBG in the first 3 NBGs comprises 2 narrow bands, each NBG in the last 2 NBGs comprises 3 narrow bands, namely, the index of the narrow band contained in the first NBG is 0-1, the index of the narrow band contained in the second NBG is 2-3, the index of the narrow band contained in the third NBG is 4-5, the index of the narrow band contained in the fourth NBG is 6-8, and the index of the narrow band contained in the fifth NBG is 9-11; for a 10MHz system bandwidth, 2,2,2,2 means to divide 4 NBGs altogether, each NBG containing 2 narrow bands;

for a 5MHz system bandwidth, 1,1,2 indicates that 3 NBGs are divided in total, each NBG in the first 2 NBGs contains 1 narrowband, and the last 1 NBG contains 2 narrowbands;

for a 3MHz system bandwidth, 1,1 indicates that 2 NBGs are divided in total, each NBG containing 1 narrowband.

The number of resource allocation bits adopted by this embodiment is the same as the resource allocation of DCI format 6-1B of Rel-13 version of LTE. This embodiment can be applied to a terminal device supporting a data bandwidth of 20 MHz. When the system bandwidth is less than or equal to 5MHz, this embodiment can also be applied to a terminal device supporting a data bandwidth of 5 MHz.

Based on the second method, the network device may determine the NBG allocated to the terminal device first, and then determine the bit state of each bit in the resource allocation information.

And in the third mode, the bit number of the resource allocation information is less than or equal to 5, and the resource allocation information is used for indicating the initial NBG and the number Z of the continuous NBGs of the allocation.

In an embodiment of the third mode, Z may be a positive integer smaller than or equal to K, K is the number of all NBGs in the system bandwidth, and the difference between the numbers of narrow bands included in any two NBGs is at most 1.

In an implementation, the narrowbands within the system bandwidth can be grouped resulting in at least one NBG. Wherein one NBG may contain at least one narrow band. In the third mode, the resources are allocated in a mode of combining the starting point and the length by taking NBG as granularity. Recording the number of NBG in the system bandwidth as N, the number of bits allocated by the resource as

In the existing LTE system, for downlink resource allocation, the resource allocation manner of the starting point combination length is Type 2 resource allocation, and for uplink resource allocation, the resource allocation manner of the starting point combination length is Type 0 resource allocationThe method. In this embodiment, the resource allocation method of the starting point combination length is similar to the existing downlink Type 2 resource allocation method/uplink Type 0 resource allocation method. Except that the granularity of the resource allocation is NBG.

A Resource Indication Value (RIV) corresponding to a binary number of one bit indicates a start NBG and the number of consecutive NBGs. The number of consecutive NBGs represented may be 1 NBG to one of all N NBGs in the system bandwidth. The NBG is divided as shown in table 10:

watch 10

System bandwidth	3MHz	5MHz	10MHz	15MHz	20MHz
						Number of narrow bands contained in system bandwidth	2	4	8	12	16
Number of NBGs included in system bandwidth	2	3	5	7	7
						Division of NBG example 1	1,1	1,2,1	1,2,2,2,1	1,2,2,2,2,2,1	3,2,2,2,2,2,3

For example, for a 20MHz system bandwidth, 3,2,2,2,2, 3 indicates that 7 NBGs are totally divided, each NBG in the 1 st and 7 th NBGs includes 3 narrow bands, and each NBG in the rest NBGs includes 2 narrow bands, that is, the first NBG includes a narrow band having an index of 0 to 2, the second NBG includes a narrow band having an index of 3 to 4, the third NBG includes a narrow band having an index of 5 to 6, the fourth NBG includes a narrow band having an index of 7 to 8, the fifth NBG includes a narrow band having an index of 9 to 10, the sixth NBG includes a narrow band having an index of 11 to 12, and the seventh NBG includes a narrow band having an index of 13 to 15;

for a 15MHz system bandwidth, 1,2,2,2,2, 1 indicates that 7 NBGs are divided in total, each of the 1 st and 7 th NBGs contains 1 narrowband, and each of the remaining NBGs contains 2 narrowbands;

for a 10MHz system bandwidth, 1,2,2,2,1 indicates that 5 NBGs are divided, each of the 1 st and 5 th NBGs contains 1 narrowband, and each of the remaining NBGs contains 2 narrowband;

for a 5MHz system bandwidth, 1,2,1 indicates that 3 NBGs are divided in total, each of the 1 st and 3 rd NBGs contains 1 narrowband, and the 2 nd NBG contains 2 narrowbands;

for a 3Hz system bandwidth, 1,1 indicates a total division of 2 NBGs, each containing 1 narrowband.

The number of resource allocation bits adopted by this embodiment is the same as the resource allocation of DCI format 6-1B of Rel-13 version of LTE. This embodiment may be applied to a UE supporting a data bandwidth of 20 MHz. This embodiment may also be applied to a UE supporting a data bandwidth of 5MHz when the system bandwidth is 5MHz or less.

Based on the third method, the network device may first determine the NBG allocated to the terminal device, that is, determine the number Z of the allocated initial NBG and consecutive NBG, and then determine the bit state of each bit in the resource allocation information.

In another embodiment of mode three, the bandwidth of Z consecutive NBGs may be less than or equal to 5MHz, and one NBG contains 1 or 2 narrow bands.

In an implementation, a narrow band within the system bandwidth may be partitioned into at least one NBG, and resources may be allocated in a manner of starting point in combination with length. In this embodiment, the resource allocation method of the starting point combination length is similar to the existing downlink Type 2 resource allocation method/uplink Type 0 resource allocation method. Except that the granularity of the resource allocation is NBG. A Resource Indication Value (RIV) corresponding to a binary number of bits of the Resource allocation indicates a start NBG and the number of consecutive NBGs. The number of consecutive NBGs, Z, is expressed as a minimum of 1, and the maximum frequency width of the Z NBGs is not more than 5 MHz. The NBG is divided as shown in table 11:

TABLE 11

The numbers corresponding to the dividing examples of the NBG indicate the number of narrow bands included in each NBG. This embodiment uses the same number of resource allocation bits as the resource allocation of format 6-1B of Rel-13 version of LTE. This embodiment may be applied to a UE supporting a data bandwidth of 5 MHz.

Step 402, in terms of physical resources, the network device receives uplink information sent by the terminal device and/or sends downlink information to the terminal device.

In implementation, after the network device allocates the physical resource to the terminal device, the network device may send downlink information to the terminal device on the physical resource, and may receive uplink information sent by the terminal device on the physical resource.

The terminal device may determine the NBG corresponding to each bit and determine whether the corresponding NBG is allocated according to the bit state of the bit. In this way, the terminal device can determine the NBG allocated by the network device according to the state of each bit in the resource allocation information.

For the specific processing procedure of the third method, reference may be made to the relevant description in step 401, and details are not described here.

In the third mode, the terminal device may analyze the resource allocation information, obtain a bit of each bit in the resource allocation information, determine the number Z of the initial NBG and the consecutive NBG according to the state of each bit, and determine the NBG, which is the physical resource allocated by the network device.

Step 603, the terminal device sends uplink information to the network device and/or receives downlink information sent by the network device on the physical resource allocated by the network device.
