Description

Method, device and device for resource allocation 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 technique

With the development of communication technologies, the application of the Long Term Evolution (LTE) system is more and more widely used, and one application thereof is for MTC (Machine Type Communication). In the LTE system, the data in the physical channel can be transmitted through a Physical Resource Block (PRB). The PRB corresponds to 12 consecutive subcarriers in the frequency domain and one time slot in the time domain (ie, half of the sub-carriers). frame). Among them, a narrow band contains the frequency width of 6 PRBs in the frequency domain. In the Rel-13 version of the LTE, the terminal device capable of supporting the MTC service is a BL (Bandwidth-Reduced Low-complexity User Equipment) or a CE UE (Coverage Enhancement User Equipment). The device has a maximum transmit and receive bandwidth of 1.4 MHz, that is, it can only accept and transmit data within a narrow band. The Rel-13 version of LTE provides two coverage enhancement modes for CE UEs, namely CE mode A (Coverage Enhancement mode A) for smaller coverage enhancement, and for greater coverage enhancement. CE mode B (Coverage Enhancement mode B).

Before the network device and the terminal device perform data transmission, the network device first allocates physical resources for transmitting data to the terminal device. The physical resource includes one or more PRBs. The network device may first determine a narrowband for data transmission of the terminal device (referred to as a target narrowband for convenience of description), and then select a PRB allocated for the terminal device among the 6 PRBs included in the target narrowband. The network device may determine the index information of the target narrowband, and may determine the allocation information of the PRB in the narrowband according to the PRB selected from the target narrowband. The allocation information of the PRB in the narrowband may be 3 bits. For example, 0-5 is used to identify 6 PRBs in the narrowband. The bit status 000 of the allocation information of the PRB in 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, if the network device is When the PRB allocated by the terminal device is 0 and 1, the state of the bit of the allocation information of the PRB in the narrowband can be determined to be 110. The network device may send the resource allocation information to the terminal device, where the resource allocation information may include the determined index information and the allocation information of the narrow-band PRB. The resource allocation rule is also stored in the terminal device, and then the corresponding PRB is determined according to the state of the bit of the resource allocation information, and the data transmission is performed based on the determined PRB.

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

In carrying out the process of the present disclosure, the inventors have found that the prior art has at least the following problems:

When allocating physical resources, the network device can only allocate physical resources to the terminal device in a narrow band. The terminal device and the network device can only transmit data on a physical resource in a narrow band, resulting in low efficiency of transmitting data.

NB _i may include physical resource blocks PRB _n , PRB _n+1 , PRB _n+2 , PRB _n+3 , PRB _n+4 , PRB _n+5 in frequency, wherein PRB _n is the smallest index value in the narrow band NB _i The PRB, also known as the first PRB. The broadband within the system bandwidth can also number each broadband in ascending order (or descending order), and the number of each broadband is the broadband index of the broadband. The index is j's broadband is WB _j . WB _j may include narrowband NB _i , NB _i+1 , NB _i+2 , NB _i+3 in frequency, where NB _i is a narrowband with the smallest index value in the wideband WB _j . For example, for a 20 MHz system bandwidth, the narrowband index is 0 to 15, the PRB index is 0 to 99, and the wideband index is 0 to 3. Where n, i, j are all non-negative integers.

When the foregoing index indication information may indicate the initial narrowband of the allocation, the specific implementation manner may include the following.

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

In an implementation, the bit status of the index indication information may indicate a narrowband index. For example, for a 20 MHz system bandwidth, the value of X is 4, and the index indication information needs to indicate that the narrowband index is one of 0, 4, 8, and 12. The index indication information may be 2 bits, including 4 different bit states. , indicating 0, 4, 8, and 12, respectively, in this case, the initial narrow band may be NB _i , and i is one of 0, 4, 8, and 12. Similarly, if the value of X is 2, the index indication information may be 3 bits, indicating that the narrowband index is one of 0, 2, 4, 6, 8, 10, 12, and 14, and the initial narrowband may be NB. _i , i is one of 0, 2, 4, 6, 8, 10, 12, 14.

(2) The index indication information is used to indicate the physical resource block PRB index, the index of the narrowband where the PRB is located is a multiple of X, the value of X is one of 4, 2, 1, and the initial narrowband is the PRB represented by the PRB index. The narrow band where it is.

In an implementation, the bit status of the index indication information may indicate a PRB index. For example, for a 10 MHz system bandwidth, the value of X is 4, the index of the narrowband in the system bandwidth is 0 to 7, and the index indication information needs to indicate one of the PRB indexes of 1 and 25, and the index indication information is 1 bit. Two different bit states are included, one of 1 and 25, respectively, in which case the starting narrowband can be NB _i and i is one of 0 and 4.

(3) The index indication information is used to indicate the broadband index, and the initial narrowband is a narrowband in the narrowband included in the wideband indicated by the wideband index with the smallest index value.

In an implementation, the bit status of the index indication information may indicate a wideband index. For example, for a 20 MHz system bandwidth, the index indication information needs to indicate that the broadband index is one of 0, 1, 2, and 3. The index indication information is 2 bits, including 4 different bit states, indicating 0, 1, 2, and respectively. One of the three, at this time, the initial narrow band may be NB _i , and i is one of 0 and 4, 8 or 12.

The index indication information can be

Bits, among them,

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

The narrowband allocation information will be described below.

In an implementation, the narrowband allocation information may be 2 bits or 3 bits, and the bit state of the narrowband allocation information may be used to indicate whether the allocated physical resource is within one narrowband or greater than one narrowband. When a resource allocation within a narrow band is indicated, the narrow band may be the starting narrow band. When indicating resource allocation greater than one narrow band, the narrowband allocation information may indicate resource allocations within consecutive G narrowbands starting from the starting narrowband, and G may be a positive integer and no more than 4 or 16.

When the narrowband allocation information indicates that the resource allocation is greater than within a narrowband, the following situations may exist:

(1) The number of bits of the narrowband allocation information may be three, 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 One or more of (NB _i , NB _i+1 , NB _i+2 , NB _i+3 ).

Where NB _i is the initial narrow band; NB _i , NB _i+1 , NB _i+2 and NB _i+3 may be four consecutive narrow bands.

This case can be applied to a scenario where the system bandwidth is greater than 3 MHz, the data bandwidth of the terminal device is equal to 5 MHz, and the 3-bit indicates that the allocated physical resources are at most 4 narrowbands, that is, 24 PRBs or one broadband. At this time, the number of resource blocks allocated by the bit state of the resource allocation information is less than or equal to 24. G does not exceed 4.

(2) the number of bits of the narrowband allocation information is 3, the physical resource narrowband allocation information distribution includes _{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 One or more of _j+2 , WB _j+3 ). Alternatively, the physical resources allocated by the narrowband allocation information include 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 One or more of ₊₂ , WB _j+3 ).

Wherein, WB _j represents a broadband composed of narrowbands NB _i , NB _i+1 , NB _i+2 , NB _i+3 ; WB _j+1 represents narrowband NB _i+4 , NB _i+5 , NB _i+6 , Broadband composed of NB _i+7 ; WB _j+2 represents a wideband consisting of narrowband NB _i+8 , NB _i+9 , NB _i+10 , NB _i+11 ; WB _j+3 represents narrowband NB _i+12 , Broadband composed of NB _i+13 , NB _i+14 , NB _i+15 ; NB _i is the initial narrow band; narrow band NB _i ～ NB _i+15 is a continuous narrow band; WB _j , WB _j+1 , WB _j+2 , WB _j+3 is a continuous broadband.

This case can be applied to a scenario where the system bandwidth is 20 MHz, the data bandwidth of the terminal device is equal to 20 MHz, and the 3-bit indicates that the allocated physical resources are at most 16 narrowbands, that is, 96 PRBs or 4 broadbands. At this time, the number of resource blocks allocated by the bit state of the resource allocation information is less than or equal to 96. G does not exceed 16.

(3) The number of bits of the narrowband allocation information is 2, and the physical resources allocated by the narrowband allocation information include (NB _i , NB _i+1 ).

Where NB _i is the initial narrow band; NB _i and NB _i+1 are two consecutive narrow bands.

This case can be applied to a scenario where the system bandwidth is 3 MHz, and 2 bits indicate that the allocated physical resources are at most 2 narrowbands.

The physical resources allocated by the narrowband allocation information may further include (PRB _n , PRB _n+1 , PRB _n+2 , PRB _n+3 ) and/or NB _i . Where NB _i is the initial narrow band, and (PRB _n , PRB _n+1 , PRB _n+2 , PRB _n+3 ) are the 4 PRBs with the smallest index among the PRBs included in NB _i . In this way, the narrowband allocation information may also indicate that the four PRBs in the narrowband are allocated and the physical resources of the entire narrowband are allocated, so that the resource allocation of the DCI (Downlink Control Information) format 6-1B of the Rel-13 version of the LTE is compatible. In this way, when the allocated physical resource is a physical resource of a group of terminal devices, such as a resource that allocates a random access response (RAR), it can provide UE and support that support a larger data bandwidth (greater than 1.4 MHz). A UE with a 1.4 MHz data bandwidth allocates the same physical resource, and avoids sending multiple sets of resources to UEs with different bandwidth capabilities, thereby improving the efficiency of resource utilization.

This embodiment provides an example of narrowband allocation information indicating resource allocation in several different scenarios, as follows.

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 that the allocated physical resources are within a narrow band, indicating whether to allocate 4 PRBs or allocate the entire narrow band (ie, 6 PRBs), respectively. The last six states indicate that the allocated physical resources are greater than one narrow band. It can be indicated that two consecutive, three or four narrow bands are allocated. The resource allocation indication of Table 2 may indicate that at most 4 narrowbands, that is, 24 PRBs or one broadband resource are allocated. The resource allocation indication of Table 2 may indicate that 4 PRBs are allocated and 1 narrow-band physical resource is allocated, so that it can be compatible with the resource allocation of the LTE Rel-13 version of DCI format 6-1B.

For the above case (1), the narrowband of the narrowband allocation information distribution may be continuous or discontinuous, such as a table. 2 shows:

Table 2

In Table 2, the first two bit states may indicate that the allocated physical resources are within a narrow band, indicating whether to allocate 4 PRBs or allocate the entire narrowband (ie, 6 PRBs), respectively. The last six states indicate that the allocated resources are greater than one narrow band. It can be indicated that 2, 3 or 4 narrow bands are allocated. When the indication is assigned 2 or 3 narrow bands, these narrow bands may be continuous or discontinuous. The resource allocation indication of Table 2 may indicate that at most 4 narrowbands, that is, 24 PRBs or one broadband physical resource are allocated. The resource allocation indication of Table 2 may indicate that 4 PRBs are allocated and 1 narrow-band physical resource is allocated, so that it can be compatible with the resource allocation of the LTE Rel-13 version of DCI format 6-1B.

For the above case (2), the narrow band of the narrowband allocation information distribution may be continuous. The physical resources allocated by the narrowband allocation information include WB _j , (WB _j , WB _j+1 ), (WB _j+1 , WB _j+2 ), (WB _j+2 , WB _j+3 ), (WB _j , One of 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 ) Kind or more. For example, Table 3 shows:

table 3

In Table 3, WB _j represents four consecutive narrowbands with narrowband NB _i as the starting, ie narrowband NB _i , NB _i+1 , NB _i+2 , NB _i+3 ; WB _j+1 denotes NB _{i+ 4} is the continuous four narrow bands of the initial narrow band, that is, the narrow bands NB _i+4 , NB _i+5 , NB _i+6 , NB _i+7 ; WB _j+2 represents the continuous narrow band of NB _i+8 as the starting 4 Narrowbands, ie narrowband NB _i+8 , NB _i+9 , NB _i+10 , NB _i+11 ; WB _j+3 denotes four consecutive narrowbands with narrowband starting from NB _i+12 , ie narrowband NB _{i+ 12} , NB _i+13 , NB _i+14 , NB _i+15 . When the state of the 3 bit is 000, it indicates that 4 PRBs are allocated, or the physical resources of the entire narrow band are allocated. The resource allocation indication of Table 3 may indicate up to 16 narrowband allocations, ie 96 PRBs or 4 broadband physical resources. The resource allocation of Table 3 includes the allocation of 4 PRBs or 1 narrowband (6 PRBs), which is compatible with the resource allocation of Rel-13.

The narrow band of narrowband allocation information distribution can also be as shown in Table 4.

Table 4

In Table 4, when the state of the 3 bit is 000, it indicates that 4 PRBs are allocated, or the physical resources of the entire narrowband are allocated. When the state of the 3bit is 001, the indication is that two consecutive narrowbands are allocated, where NB _i and NB _i+1 may be two narrow bands with the smallest index value in WB _j . The last six states indicate that the allocated physical resources are greater than or equal to 1 broadband.

For the above case (2), narrow-band narrowband allocation information may be continuous, or may be discontinuous, physical resource narrowband allocation information distribution 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 One or more of WB _j+2 , WB _j+3 ), (WB _j , WB _j+1 , WB _j+2 , WB _j+3 ). When eight narrowbands are allocated, the resource allocation indicated by the state of the bit includes one or more of (WB _j , WB _j+1 ), (WB _j , WB _j+2 ), (WB _j , WB _j+3 ) Kind. When 12 narrowbands are allocated, the resource allocation indicated by the 3-bit state includes (WB _j , WB _j+1 , WB _j+2 ), (WB _j , WB _j+1 , WB _j+3 ), (WB _j , One or more of WB _j+2 , WB _j+3 ). The narrow band of narrowband allocation information distribution can 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 distribution can be as shown in Table 7:

Table 7

In Table 7, the narrowband allocation information may indicate up to 2 narrowbands, that is, physical resources of 12 PRBs. The resource allocation of Table 7 can be applied to a terminal device supporting a data bandwidth of 5 MHz, and can 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 in the narrowband are allocated, and the entire narrowband physical resource is allocated, so that it is compatible with the resource allocation of the DCI format 6-1B of the Rel-13 version of LTE.

In mode 1, the number of bits of resource allocation information can be as shown in Table 8:

Table 8

It should be noted that, in the first mode, for a terminal device supporting a data bandwidth of 20 MHz, when the system bandwidth is less than 20 MHz and greater than 3 MHz, if the bit state of the narrowband allocation information, the narrowband index indicated by a certain bit state exceeds the system. The narrowband allocation information is invalid within the bandwidth, and the narrowband allocation information is invalid.

Or, for a terminal device supporting a data bandwidth of 20 MHz, when the system bandwidth is less than 20 MHz and greater than 3 MHz, if the bit state of the narrowband allocation information, the narrowband index indicated by the bit state exceeds the maximum value of the narrowband index in the system bandwidth, Then, in the index of the narrow band indicated by the narrowband allocation information, a narrow band indicated by an index value not exceeding the maximum value of the narrowband index in the system bandwidth is effective.

Optionally, the value of X may be determined according to a system bandwidth of the network device. When the system bandwidth is a first network device system bandwidth, or narrow-band index PRB index narrowband where X is a multiple of _1; a network device when the system bandwidth is the second system bandwidth, the narrow band where the narrowband PRB index or index Is a multiple of X ₂ .

Alternatively, the value of X can be determined according to the data bandwidth supported by the terminal device. When the terminal device is supported by a first data bandwidth data bandwidth, or narrow-band narrowband PRB index where the index is a multiple X _1; narrowband when the terminal device is supported by the data bandwidth of the second data bandwidth, where the narrowband PRB index or The index is a multiple of X ₂ .

Wherein the first system bandwidth is greater than a second system bandwidth; a first data bandwidth greater than the second data width, X ₁ is greater than X _2, X _1, X ₂ is a value of each of 4,2,1.

Based on the above processing, a larger granularity allocation mode can be adopted for a larger system bandwidth, and a smaller granularity allocation mode can be adopted for a smaller system bandwidth. Similarly, for larger data bandwidths, a larger granularity allocation scheme can be used; for smaller data bandwidths, a smaller granularity allocation scheme can be employed. In this way, the granularity of the allocation can be matched with the current system bandwidth or network bandwidth, thereby improving the rationality of resource allocation.

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

In the second mode, the number of bits of the resource allocation information is less than or equal to 5, the number of bits of the resource allocation information is the same as the number of the narrowband group NBG, and each bit of the resource allocation information corresponds to one NBG, and the two states of each bit represent corresponding Whether the physical resources contained in the NBG are allocated.

In an implementation, narrowbands within the system bandwidth may be grouped to obtain at least one Narrowband Group (NBG). Wherein, one NBG may include at least one narrow band. In the second method, the NBG is used as the granularity, and the resource allocation is performed by using the bit mapping method. The number of bits of the resource allocation information may be the same as the number of divided NBGs, each The NBG can be mapped to a bit, and the two bit states of the bit can 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. If a certain NBG is allocated, all PRBs in the NBG are allocated. In the second mode, the difference between the number of narrowbands included in any two NBGs does not exceed one.

The NBG can be divided according to Table 9 in different system bandwidths:

Table 9

The number corresponding to the NBG partitioning example indicates the number of narrowbands included in each NBG.

For example, for a 20 MHz system bandwidth, 3, 3, 3, 3, 4 means that a total of 5 NBGs are divided. Each of the first 4 NBGs includes 3 narrowbands, and the latter NBG includes 4 narrowbands, that is, the first NBG. The index of the narrowband included is 0 to 2, the index of the narrowband included in the second NBG is 3 to 5, the index of the narrowband included in the third NBG is 6-8, and the index of the narrowband included in the fourth NBG is 9 to 11, the fifth NBG contains a narrowband index of 12 to 15;

For a 15 MHz system bandwidth, 2, 2, 2, 3, 3 means that a total of 5 NBGs are divided. Each of the first 3 NBGs includes 2 narrowbands, and each of the last 2 NBGs includes 3 narrowbands, that is, The first NBG includes a narrowband index of 0 to 1, the second NBG includes a narrowband index of 2 to 3. The third NBG includes a narrowband index of 4 to 5. The fourth NBG includes a narrowband. The index is 6-8, the fifth NBG contains a narrowband index of 9-11; for a 10MHz system bandwidth, 2, 2, 2, 2 means that a total of 4 NBGs are divided, and each NBG includes 2 narrowbands;

For a 5 MHz system bandwidth, 1, 1, 2 indicates that a total of three NBGs are divided. Each of the first two NBGs includes one narrowband, and the latter NBG includes two narrowbands.

For a 3 MHz system bandwidth, 1, 1 means that a total of 2 NBGs are divided, and each NBG contains 1 narrow band.

The number of resource allocation bits used in this embodiment is the same as the resource allocation of the DCI format 6-1B of the 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 5 MHz, 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 first determine the NBG allocated to the terminal device, and then determine the bit status of each bit in the resource allocation information.

In the third mode, the number of bits of the resource allocation information is less than or equal to 5. The resource allocation information is used to indicate the allocated starting NBG and the number Z of consecutive NBGs.

In an implementation manner of the third method, Z may be a positive integer less than or equal to K, K is the number of all NBGs in the system bandwidth, and the difference between the narrowband numbers included in any two NBGs is at most 1.

In an implementation, narrowbands within the system bandwidth can be grouped to obtain at least one NBG. Wherein, one NBG may include at least one narrow band. In the third method, the NBG is used as the granularity, and the resources are allocated by using the starting point and the length. Note that the number of NBGs in the system bandwidth is N, and the number of bits allocated by the resource is

In the existing LTE system, for the downlink resource allocation, the resource allocation mode of the starting point combined length is the type 2 Type 2 resource allocation mode. For the uplink resource allocation, the resource allocation mode of the starting point combined length is the type 0 Type 0 resource allocation mode. In this embodiment, the resource allocation manner of the starting point combined length is similar to the existing downlink Type 2 resource allocation manner/uplink Type 0 resource allocation manner. The difference is that the granularity of resource allocation is NBG.

The Resource Indication Value (RIV) corresponding to the binary number of bits represents a starting NBG and a continuous number of NBGs. The number of consecutive NBGs indicated may be one of all N NBGs in one NBG to system bandwidth. An example of how NBG is divided is shown in Table 10:

Table 10

System bandwidth	3MHz	5MHz	10MHz	15MHz	20MHz
The number of narrow bands included in the system bandwidth	2	4	8	12	16
The number of NBGs included in the system bandwidth	2	3	5	7	7
NBG division example one	1,1	1,2,1	1,2,2,2,1	1,2,2,2,2,2,1	3,2,2,2,2,2,3
NBG division example two	1,1	1,2,1	2,1,2,1,2	2,2,1,2,1,2,2	2,2,3,2,3,2,2
Number of bits allocated by resource	2	3	4	5	5

The number corresponding to the NBG partitioning example indicates the number of narrowbands included in each NBG.

For example, for a 20 MHz system bandwidth, 3, 2, 2, 2, 2, 2, 3 means that a total of 7 NBGs are divided, and each of the first and seventh NBGs includes three narrowbands, and the remaining NBGs Each NBG includes two narrowbands, that is, the index of the narrowband included in the first NBG is 0 to 2, the index of the narrowband included in the second NBG is 3 to 4, and the index of the narrowband included in the third NBG is 5-6. The fourth NBG includes a narrowband index of 7-8, the fifth NBG includes a narrowband index of 9-10, the sixth NBG includes a narrowband index of 11-12, and the seventh NBG includes a narrowband. The index is 13 to 15;

For a 15 MHz system bandwidth, 1, 2, 2, 2, 2, 2, 1 means that a total of 7 NBGs are divided, and each of the 1st and 7th NBGs includes 1 narrowband, and each of the remaining NBGs NBG contains 2 narrow bands;

For a 10 MHz system bandwidth, 1, 2, 2, 2, 1 means that a total of five NBGs are divided, and each of the first and fifth NBGs includes one narrow band, and each of the remaining NBGs includes two. Narrow band

For a 5 MHz system bandwidth, 1, 2, 1 means that a total of three NBGs are divided, and each of the first and third NBGs includes one narrow band, and the second NBG includes two narrow bands;

For a 3 Hz system bandwidth, 1, 1 means that a total of 2 NBGs are divided, and each NBG contains 1 narrow band.

The number of resource allocation bits used in this embodiment is the same as the resource allocation of the DCI format 6-1B of the Rel-13 version of LTE. This embodiment can be applied to UEs that support a data bandwidth of 20 MHz. This embodiment can also be applied to UEs supporting a data bandwidth of 5 MHz when the system bandwidth is less than or equal to 5 MHz.

Based on mode 3, the network device may first determine the NBG allocated to the terminal device, that is, determine the initial NBG of the allocation and the number Z of consecutive NBGs, and then determine the bit status of each bit in the resource allocation information.

In another implementation of mode three, the bandwidth of the Z consecutive NBGs may be less than or equal to 5 MHz, and one NBG includes one or two narrowbands.

In an implementation, a narrow band within a system bandwidth may be divided into at least one NBG, and resources are allocated in a manner that combines a starting point and a length. In this embodiment, the resource allocation manner of the starting point combined length is similar to the existing downlink Type 2 resource allocation manner/uplink Type 0 resource allocation manner. The difference is that the granularity of resource allocation is NBG. A Resource Indication Value (RIV) corresponding to a binary number of bits of resource allocation indicates a starting NBG and a continuous number of NBGs. The number of consecutive NBGs represented by Z is a minimum of 1, and the maximum bandwidth of Z NBGs is not more than 5 MHz. An example of how NBG is divided is shown in Table 11:

Table 11

The number corresponding to the partitioning example of the NBG indicates the number of narrowbands included in each NBG. The number of resource allocation bits used in this embodiment is the same as the resource allocation in format 6-1B of the Rel-13 version of LTE. This embodiment can be applied to UEs that support a data bandwidth of 5 MHz.

Step 402: On the physical resource, the network device receives the uplink information sent by the terminal device and/or sends the uplink information to the terminal device. Downstream information.

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

This embodiment provides a method for resource allocation, which can be performed by a user terminal. As shown in FIG. 6, the processing flow of the method can be as follows:

Step 601: The terminal device receives resource allocation information sent by the network device.

The resource allocation information is used to allocate physical resources, the number of bits of the resource allocation information is less than or equal to 7 bits, and the number of physical resource blocks PRB allocated by at least one bit state of the resource allocation information is greater than 6, and the bits of the resource allocation information The number of resource blocks allocated by the state is less than or equal to 96.

In an implementation, after the network device sends the resource allocation information to the terminal device, the terminal device may receive the resource allocation information, and then obtain the bit state of the resource allocation information.

Step 602: The terminal device determines, according to the bit status of the resource allocation information, a physical resource allocated by the network device.

In an implementation, after acquiring the bit status of the resource allocation information, the terminal device may determine the physical resource indicated by the bit status of the received resource allocation information according to the manner in which the pre-stored resource allocation information indicates the allocated physical resource.

The manner in which the resource allocation information indicates the allocated physical resources may be various. This embodiment provides several feasible processing manners, as follows.

In a first manner, the resource allocation information may include index indication information and narrowband allocation information, the index indication information may be used to indicate a starting narrowband of the allocation, and the narrowband allocation information may be used to indicate resource allocation in consecutive G narrowbands starting from a starting narrowband. , G is a positive integer and is less than or equal to 16, as shown in FIG. 5a, is a schematic diagram of resource allocation information, as shown in FIG. 5b, a schematic diagram of physical resources allocated for resource allocation information, wherein the system bandwidth is 20 MHz.

For the specific processing of the first method, refer to the related description in step 401, and details are not described herein again.

In the first method, the terminal device may parse the resource allocation information, obtain the index indication information and the narrowband allocation information, and then determine the corresponding initial narrowband according to the obtained index indication information, and may obtain the narrowband according to the obtained The allocation information determines consecutive G narrowbands starting from the first starting narrowband, and determines the physical resources allocated by the network device from the consecutive G narrowbands.

In the second mode, the number of bits of the resource allocation information is less than or equal to 5, the number of bits of the resource allocation information is the same as the number of the narrowband group NBG, and each bit of the resource allocation information corresponds to one NBG, and the two states of each bit represent corresponding Whether the physical resources contained in the NBG are allocated.
