Description

Resource allocation method and device

Technical Field

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

Background

In the related art, in Long Term Evolution (LTE) and LTE-Advanced (LTE-a) systems, a base station carries Resource allocation information of a Physical Downlink Shared Channel (PDSCH) and a Physical Uplink Shared Channel (PUSCH) respectively through Downlink scheduling allocation and Uplink scheduling request information, and a User terminal (UE) receives Downlink information or transmits Uplink information on a corresponding Resource Block (RB) according to the received Resource allocation information.

The Resource allocation method for the PDSCH includes three types, where the downlink Resource allocation type 0 is bitmap (bitmap) mapping allocation, that is, whether to schedule is indicated by 1 bit for each scheduling Resource unit, and the scheduling Resource unit is a Resource Block Group (RBG) and supports discontinuous RB scheduling. The downlink resource allocation type1 firstly indicates the RBG subset used by the UE by using one or more bits, and then adopts a bitmap mapping method in the subset to also support discontinuous RB scheduling. The downlink Resource allocation type 2 indicates a continuous RB Resource allocated to the UE by a coded Resource Indication Value (RIV), where RIV is a joint code of a start position and a length of the allocated Resource.

The resource allocation for the uplink PUSCH includes two allocation manners, and the uplink resource allocation type 0 is a continuous resource allocation manner and is the same as the downlink resource allocation type 2. The uplink resource allocation type1 supports non-contiguous RB allocation of up to two clusters, each cluster includes one or more contiguous RBGs, and the start resource index and the end resource index of the two clusters are jointly encoded.

However, considering characteristics of New air interface/Radio (NR), such as large system bandwidth, dynamic traffic load change, multiple subcarrier intervals, etc., if the existing resource allocation method is multiplexed, a large overhead is incurred, and flexibility of resource allocation is limited. For example, in the conventional NR, the system bandwidth of one carrier may reach 400MHz, and the number of carriers corresponding to the system bandwidth may be one of 3300 to 6600 (correspondingly, the number of PRBs corresponding to the system bandwidth is at least 275). For such a large system bandwidth, resources on the entire system bandwidth may be allocated to the UE in a manner similar to resource allocation in LTE. For the case of allocating the entire large bandwidth to the UE, the signaling overhead will be significantly increased according to the existing resource allocation method. In another way, a part of bandwidth in the whole large bandwidth is configured for the UE, but the bandwidth is still much larger than the system bandwidth configured for the UE in the existing LTE, and the problem of significant signaling overhead increase also exists.

In view of the above problems in the related art, no effective solution has been found.

It should be noted that, the above modules may be implemented by software or hardware, and for the latter, the following may be implemented, but not limited to: the modules are all positioned in the same processor; alternatively, the modules are respectively located in different processors in any combination.

Example 3

The embodiment provides a resource allocation indication method, which can reduce signaling overhead and improve flexibility of resource allocation.

The scheme in the embodiment is suitable for PDSCH and PUSCH resource allocation. Also, the existing method for indicating the PDSCH and the PUSCH resource allocation is also applicable. The present invention is not limited to a certain scenario, and can be applied to any scenario for indicating resource allocation. The resource granularity which can be indicated or characterized by the given resource allocation indication mode of the invention comprises at least one of the following: RB, RBG, RE, REG, subband.

The resource allocation indication method provided by this embodiment includes at least one of the following methods:

the first mode is as follows: the base station indicates a bandwidth mode to the terminal; second, resource allocation information in the bandwidth mode is indicated.

The band mode includes at least one of: a full bandwidth mode; almost full bandwidth mode; partial bandwidth mode.

Wherein: the almost full bandwidth mode refers to almost full bandwidth for the allocated resources. Conversely, only a very small portion of the resources on the entire bandwidth are unoccupied. The unoccupied resources are few with respect to the entire bandwidth resources. The partial bandwidth mode means that the allocated resources occupy only a portion of the entire bandwidth. The occupation situation of almost full bandwidth mode indication resources is larger than the situation of partial bandwidth mode indication resources occupation.

In case the bandwidth mode is an almost full bandwidth mode, or a partial bandwidth mode, optionally, the base station may further indicate the bandwidth situation by: case one, indicating the case of occupied bandwidth. And in case two, indicating the bandwidth occupation situation. This has the advantage of reducing signalling or indication overhead to some extent for large bandwidth or large number of occupied resources.

In the indication of the resource allocation information, the base station can indicate the occupied resource condition in the corresponding bandwidth mode for the terminal; or, the base station indicates the unoccupied resource condition in the corresponding bandwidth mode for the terminal. For the latter, the terminal can calculate the self occupied resource condition according to the resource condition which is not occupied.

The second mode is as follows: the base station indicates the bandwidth to the terminal; second, resource allocation information on the bandwidth is indicated.

For the second method, the bandwidth indicated by the base station for the terminal may be two cases: indicating bandwidth information of occupied resources under the condition of one; and in case two, bandwidth information indicating unoccupied resources. In case two, the base station needs to calculate and acquire the bandwidth information of the resources occupied by the base station through the bandwidth information of the unoccupied resources.

In the indication of the resource allocation information, the base station can indicate the occupied resource condition under the corresponding bandwidth for the terminal; or, the base station indicates the unoccupied resource condition under the corresponding bandwidth for the terminal. For the latter, the terminal can calculate the self occupied resource condition according to the resource condition which is not occupied.

The third mode is as follows: the resource allocation information is directly indicated.

For the third mode, the base station does not need to indicate bandwidth information where resources are allocated. The bandwidth information may be predefined in advance, or configured by higher layer radio resource control RRC signaling, or default bandwidth. The bandwidth may be a full bandwidth, or a certain sub-band or RBG or REG in the entire bandwidth.

In the indication of the resource allocation information, the base station can indicate the occupied resource condition for the terminal; or, the base station indicates the unoccupied resource condition for the terminal. For the latter, the terminal can calculate the self occupied resource condition according to the resource condition which is not occupied.

In the above three ways, please refer to the contents of the embodiments for more detailed ways of indicating the bandwidth and indicating the resource allocation location information under the specified bandwidth and for signaling design contents.

Optionally, without loss of generality, the method of this embodiment may be extended to a multi-step or nested resource allocation method.

The first implementation mode comprises the following steps:

the present embodiment provides a resource allocation method. Specifically, the manner of indicating resource allocation includes at least one of the following:

The specific manner of indicating the specific occupied or unoccupied resource condition is specifically described in the following embodiments.

Further, without loss of generality, this approach can be extended to a multi-step or nested resource allocation approach.

The following embodiments will further describe the resource allocation manner in the first embodiment in detail.

The second embodiment:

this embodiment provides a bandwidth indication method. This embodiment is mainly used to further explain the indication manner of the related bandwidth in the first embodiment.

The indication mode of the bandwidth comprises at least one of the following modes:

the first method is as follows: the bandwidth information is indicated by means of a bitmap (bitmap).

Specifically, the bandwidth information allocated to the terminal is indicated by a bitmap. Bitmap co-containmentBits, each bit corresponding to a subband, the highest bit representing subband 0 and the lowest bit representing subband N_bandwidth-1, and so on. Alternatively, the formula for calculating the number of bits contained in the bitmap can also be used for replacing the bandwidth of the BW systemAnd replacing the sub BW sub bandwidth with the corresponding RB number or RBG number or RE number. If a certain sub-band is allocated to a certain terminal, the corresponding bit in the bitmap is set to 1; otherwise, if a certain sub-band is not allocated to a certain terminal, the corresponding bit in the bitmap is set to 0.

The second method comprises the following steps: the bandwidth information is indicated by a bandwidth mode field or field.

Specifically, the bandwidth information allocated to the terminal is indicated by one bandwidth mode field or field. The bandwidth mode field or field contains a total of n bits. The different bandwidth modes are indicated by corresponding different bit positions 0 or 1 in the n bits. Wherein n is a positive integer greater than or equal to 1.

Alternatively, n bits may be used all for indicating the bandwidth mode. Alternatively, one of the n bits is used to indicate whether the mode is indicated for occupied resources or bandwidth. Preferably, the highest bit or the lowest bit is used to indicate whether the mode is the occupied resource or bandwidth indication mode. The remaining bits are used to indicate the bandwidth mode.

For example, the bandwidth mode field or field may be 2 bits, which may indicate at least one of the following situations: a no bandwidth mode; a full bandwidth mode; almost full bandwidth mode; partial bandwidth mode. It is not limited to specifically use which of "00", "01", "10", "11" indicates one of the above-described bandwidth modes.

As another example, the bandwidth mode field or field employs 1 bit to indicate whether full bandwidth mode or non-full bandwidth mode. As another example, 2 bits are used, the highest bit is used to indicate whether the mode is occupied resource or bandwidth indication mode, and the remaining 1 bit is used to indicate whether the mode is full bandwidth mode or non-full bandwidth mode.

Without loss of generality, the method can also be used in other scenarios of similar problems, and is not limited to the scenario or the method described in this embodiment or the present invention.

The manner in which the bandwidth is indicated is schematically illustrated in fig. 3 as an example. Fig. 3 is a schematic diagram of bandwidths allocated by a base station to a terminal in an embodiment of the present invention. The base station indicates bandwidth information allocated for the terminal in a bandwidth mode field in specific signaling. The specific signaling or the first signaling may be a higher layer radio resource management RRC signaling or a physical layer downlink control information DCI signaling. The DCI signaling may be uplink dedicated DCI signaling, or downlink dedicated DCI signaling, or shared DCI signaling.

The third method comprises the following steps: the bandwidth information is indicated by a bandwidth indication field or field.

Specifically, the bandwidth information allocated to the terminal is indicated by one bandwidth indication field or field. The bandwidth field or field may be represented in m bits. Wherein m is a positive integer greater than or equal to 1.

Alternatively, m bits may be used to indicate the bandwidth information all together. Alternatively, one of the m bits is used to indicate whether the mode is indicated for occupied resources or bandwidth. Preferably, the highest bit or the lowest bit is used to indicate whether the resource is occupied or the bandwidth is indicated. The remaining bits are used to indicate bandwidth information. For example, when m is 1, setting m to 1 indicates that the resource bandwidth is not occupied, and conversely, setting m to 0 indicates that the resource bandwidth is occupied. As another example, when m is 1, setting m to 1 indicates a non-full bandwidth, or, partial bandwidth condition. Conversely, setting m to 0 indicates a full bandwidth condition.

For another example, when m is 2, the highest bit position 0 indicates the full bandwidth mode, and the highest bit position 1 indicates the non-full bandwidth mode. The lowest bit position of 0 represents the occupied resource indication, and the lowest bit position of 1 represents the unoccupied resource condition. The non-occupied resources in the present invention are actually the complement of the occupied resources.

Optionally, a field or field indicating whether to occupy resources and/or bandwidth may be introduced to occupy X bits. X is a positive integer greater than or equal to 1. For example, one bit indicates information whether to indicate occupation of resources, and/or occupation of bandwidth. If the indication is that the resource is occupied and/or the bandwidth is occupied, the corresponding bit is 0. Otherwise, if the information of the unoccupied resources and/or the unoccupied bandwidth is indicated, the corresponding bit is 1.

Optionally, the information for indicating whether the currently indicated resource or bandwidth is an occupied resource or bandwidth is also indicated in combination with the information indicating the corresponding resource allocation or bandwidth indication.

The description in the present embodiment is merely an example of this embodiment, and is not limited to the setting, value, or expression in the example.

In addition, the field or bitmap information for indicating the bandwidth information is carried in at least one of the following signaling: high-level radio resource management RRC signaling, or physical layer downlink control information DCI signaling, or MAC signaling. The DCI signaling may be uplink dedicated DCI signaling, downlink dedicated DCI signaling, or shared DCI signaling.

The third embodiment is as follows:

the present embodiment provides an indication method of resource allocation. This embodiment is mainly used to further explain the indication method of related resource allocation in the first embodiment.

Here, the resource allocated to the terminal by the base station is referred to the entire system bandwidth. In the present embodiment, the frequency domain resource allocation method is used as an example, but the method is not limited to the use in the frequency domain, and the time domain is also applicable. For example, the frequency domain reference is adjusted to be a time domain reference, such as a subframe, a slot, a time window, a radio frame, a symbol, any combination thereof, and so on.

The indication mode of the resource allocation comprises at least one of the following modes:

the first method is as follows: and indicating the resource allocation information by using a bitmap (bitmap) mode.

The bitmap may indicate the following: in case one, indicating resources occupied by allocated devices (base stations or terminals); in case two, the unoccupied resources allocated to the device (base station or terminal) are indicated.

For the first mode, no matter whether the bitmap indicates resource occupation or resource occupation, in a large bandwidth scene, if the RBG is used as the minimum resource allocation granularity, the existing corresponding relationship between the bandwidth and the RBG size cannot meet the requirement. On the other hand, this approach also fails to allocate resources per a single RB. This will cause a large waste of resources for small traffic load situations, if the resources are still allocated in this way. However, if the resource allocation is performed with the minimum granularity according to the RB, a problem of large signaling or bit overhead occurs.

To reduce the bit overhead, the following method can be used: and modifying the corresponding relation between the RBG size and the bandwidth.

In the existing LTE, the correspondence between the system bandwidth and the RBG Size is shown in table 1. Note: the sub-carriers are spaced apart by 15 KHz.

TABLE 1

However, for NR, different subcarrier spacings are supported and are denoted by 15KHz x2 n. n is a positive integer greater than or equal to 0. For example, 15KHz, 30KHz, 60KHz, 120KHz, 240KHz, 480KHz, etc. Further, the bandwidth required to be supported in NR is at least 100MHz, up to 400MHz, or even more. In this case, if the subcarrier spacing adopted by the device is still 15KHz, the number of PRBs corresponding to the minimum supported bandwidth of 100KHz is 500, and the existing corresponding relationship between the PRBs of LTE and RBG Size cannot meet the requirement. At this time, a new bandwidth-to-RBG Size relationship needs to be defined. On the contrary, if the device uses a larger subcarrier spacing, the correspondence between the bandwidth and the RBG Size in table 1 above is still available. However, when the number of PRBs corresponding to the configured specific subcarrier spacing does not satisfy the situation given in table 1, for example, as shown in table 2, a new correspondence relationship needs to be defined to accommodate the situation where the number of PRBs is greater than that of the PRBs in the existing table.

TABLE 2

The definition of the correspondence between the new bandwidth and the RBG can consider the following aspects: the first aspect is as follows: the bit included in the bitmap indication is not increased. The second aspect is that: a trade-off between increasing bit overhead and granularity of resource allocation.

TABLE 3

Table 3 definition of RBG Size under the condition that existing bitmap contains bits, and table 3 only gives the corresponding RBG Size under some typical bandwidths, under the condition that the bitmap which originally indicates resource allocation occupies the same bits (for example, the maximum 20M bandwidth corresponds to RBG of 4, and the maximum bit occupied by bitmap is 25). The RBG Size cases corresponding to other bandwidths are not listed one by one, and the method is similar. As can be seen from table 3, in this way, the number of RBs included in one RBG is large, which is not beneficial to allocating resources to terminals with small loads, and if resource allocation is performed in this way, a certain resource waste problem will be caused.

Based on this, another way is to increase the number of bits contained in bitmap appropriately to compromise the case where the number of RBs contained in one RBG is large. For example, for the 100MHz case, at a subcarrier spacing of 15KHz, its corresponding RBG size may be 10 and its bitmap corresponding bits 50. The formula for calculating the bit occupied by the bitmap isOne of the above parameters can be determined by the subcarrier spacing, the number of bits contained in the bitmap, the number of occupied RBs, and the RBG size.

The second method comprises the following steps: the assigned resources are indicated with RIVs. The Resource Indication Value (RIV) is used to indicate a continuous segment of resources allocated to the UE, wherein the RIV is a joint code for a starting position and a length of the allocated resources.

Different from the existing LTE, the RIV described in the present invention can be used to indicate resources not allocated to a UE, in addition to indicating resources allocated to a terminal UE. The unallocated resource is not occupied by the UE. The UE can determine the self resource allocation condition through the unallocated resources configured by the base station.

The indication of resource allocation is included in DCI format X signaling. The DCI format X can be 1A/1B/1D/1C/0A/0B/4A/4B. For the uplink Resource allocation, the Resource allocation of DCI format0A/0B is specified by the "Resource block allocation and hopping Resource allocation" field. For DCIformat 4A/4B, its Resource allocation is specified by a "Resource block assignment" field. In order to inform the terminal whether the allocated resource is a resource occupied by itself or a resource that cannot be occupied by itself (i.e., an unoccupied resource), it is necessary to add a content indicating a resource attribute to the DCI format. The resource attribute is used to indicate whether the resource indicated in the DCI may be occupied or not occupied. The specific way for increasing the resource attribute includes at least one of the following:

the method comprises the following steps: and adding an occupied resource/unoccupied resource identification field in the DCI format, and using t bits for representation. The DCI format may be a format indicating resource allocation in the existing LTE technology, and other newly defined formats. t is a positive integer greater than or equal to 1.

For example, for PDSCH, the content in DCI format 1A/1B/1D/1C used to characterize resource allocation may include one of the following indications:

the centralized/distributed VRB assignment flag takes 1 bit.

Resource block assignment field, wherein localized VRB, occupiesA bit; distributed VRBs, represented by bits indicated in existing LTE.

Occupied resource/unoccupied resource identification field, using t bits. For example, the flag is 1 bit, the setting of the field to 0 indicates occupied resources, and the setting of the field to 1 indicates unoccupied resources. If the field is not included in the DCI format, it indicates that the indicated resource allocation is a resource that needs to be occupied.

For the PUSCH, the description is not repeated here similarly.

The second method comprises the following steps: the attribute indicating the resource is implicitly known by using a bit for indicating the localized/distributed in the existing DCI format. This approach may limit the flexibility of the manner in which occupied/unoccupied resources are indicated to some extent.

For example, a 0 for this bit indicates occupied resources (or unoccupied resources) and/or centralized VRB allocation. Conversely, bit position 1 indicates that unoccupied resources (or occupied resources) and/or distributed VRB assignments are indicated.

The third method comprises the following steps: for the indication resource block assignment field, t extra bits are added. The incremented bit may be located most significant or least significant. The meaning of the other bit representations remains unchanged. t is a positive integer greater than or equal to 1.

For example, the original resource block assignment field is represented by 5 bits. To indicate whether the current resource indicates an occupied or unoccupied resource situation, 1 bit is introduced, preferably the new bit is placed in the highest bit that is not used to calculate the RIV value. After the newly added highest-order bit needs to be removed in the calculation of the RIV value, the binary bit is converted into a decimal RIV value, and then the initial position and the sum of the length of the resource are obtained.

The third method comprises the following steps: adapted to indicate non-contiguous resource allocations. For PDSCH, VRBs allocated to UE are indicated by d fields through DCI format 1/2/2A/2B/2C or other formats in resource allocation TYPE 1. In a large bandwidth scenario, a great bit overhead will be caused by continuing to use the existing bitmap mode in the type1 mode to indicate the resource condition.

Based on this, other ways may be employed to indicate the condition that the device is not occupying resources, to reduce bit overhead. Other ways described herein are ways other than bitmap. The indication of an unoccupied resource situation is when the number of occupied resources is (much) larger than the unoccupied resource.

In type1, the resource allocation is specifically as follows, including at least one of the following:

the first domain containsBits specifying the selected RBG or REG or subset of subband groups, i.e., the value of p. P is the size of the RBG or REG or subband group.

The second field contains 1 bit to specify whether the resources within the subset are offset. Or, the second field contains 2 bits, and newly introduced 1 bit is used for specifying whether the resource is an occupied resource. The 2 bits may be combined to indicate the offset in the subset and whether the resource is occupied, or each bit may be used to indicate the offset in the subset and whether the resource is occupied, respectively.

The third field includes an identifier r. The r indicates the start of k resource sets, and the end position index. k may be a positive integer greater than or equal to 2. The resource may be an RBG or REG or a subband group. Each resource set corresponds to a contiguous segment of resources.Wherein, N is the number of RB/RBG or RE/REG or sub-band/sub-band group; m is the number of the starting point and the ending point corresponding to all the sets.

A field (t bit occupied) is newly introduced to specify whether the resource is an occupied resource or not.

If the DCI received by the terminal carries information indicating occupied resources or unoccupied resources, the resource allocation indication field correspondingly indicates occupied resources or unoccupied resources.

For the PUSCH, in the resource classification type1, a field indicating occupied resource/unoccupied resource is newly introduced in DCI format0A/0B/4A/4B or other format, t bits are occupied, and t is a positive integer greater than or equal to 1. The r value indicated by the resource allocation assignment corresponds to an r value corresponding to an occupied resource or an unoccupied resource. The terminal can acquire the start and end position information of the resource based on the r value. Particularly, if the occupied resource/unoccupied resource indication field indicates unoccupied resources, the terminal needs to indirectly obtain the condition of the occupied resources through the unoccupied resource information indicated by r. The occupied resources are the complement of the unoccupied resources.

The fourth embodiment:

this embodiment provides a specific implementation of the above embodiment. Here, an indication manner of a piece of continuous resource allocation is given.

Fig. 4 is a diagram illustrating a segment of continuous resource allocation according to an embodiment of the present invention. In fig. 4, a gray area is an occupied bandwidth allocated to the terminal by the base station, and a gray square area is a continuous resource allocated to the terminal by the base station under the occupied bandwidth configured for the terminal.

As shown in fig. 4, the bandwidth allocated by the base station to the terminal occupies a relatively large proportion of the whole system bandwidth. In order to reduce bit overhead caused by directly indicating the information of occupied bandwidth to the terminal, the base station indicates the information of unoccupied bandwidth for the terminal, thereby indirectly obtaining the information of occupied bandwidth.

Further, whether the bandwidth currently indicated to the terminal is occupied or unoccupied. And/or how to indicate the resources of the bandwidth. At least one of the following may be carried in signaling (physical layer DCI signaling, or higher layer RRC signaling):

occupied bandwidth/unoccupied bandwidth field occupying t1 bits; for example, t1 occupies 1 bit, 0 represents the occupied resource (e.g., bandwidth) case, and 1 represents the unoccupied resource (e.g., bandwidth).

A bandwidth resource allocation field occupying t2 bits; the number of bits occupied by t2 is related to the bandwidth resource, whether it is a continuous resource or a discontinuous resource. The indication manner of the continuous bandwidth or the discontinuous bandwidth resource is detailed in the third embodiment for the continuous resource and the corresponding content in the discontinuous resource allocation. For example, as shown in fig. 4, the unoccupied bandwidth is indicated to the terminal, and an RIV value is obtained by encoding the starting resource location index X1 and the length L, and t2 bits of the field correspond to a decimal number corresponding to the RIV and are converted into a binary number. Non-contiguous resource allocation in a manner similar to the way resources are characterized in type 1.

A subcarrier spacing indication field occupying t3 bits; for example, the existing subcarrier spacing is: 15KHz, 30KHz, 60KHz, 120KHz, 240KHz, 480KHz, etc. In order to indicate the subcarrier interval used for resource allocation, the subcarrier configured for the terminal or the subcarrier set may be indicated in the same bitmap manner. For example, 110000 indicates that the terminal is configured with 15KHz and 30 KHz. To reduce the bit overhead, the subcarrier spacing can be represented by 3 bits, e.g., 000 for 15KHz, 001 for 30KHz, 010 for 60KHz, 011 for 120KHz, 100 for 240KHz, and 101 for 480 KHz.

Through the bandwidth field, the terminal can indirectly obtain the information of the occupied bandwidth position (for example, through the system bandwidth, the unoccupied bandwidth, the occupied bandwidth is the complement of the unoccupied bandwidth in the system bandwidth). Further, referring to fig. 4, the terminal may obtain the resource actually allocated to the terminal by the base station according to the resource allocation indication signaling (e.g., physical layer DCI signaling) under the occupied bandwidth. The method comprises the following specific steps:

first, a terminal is directly configured with an occupied section of continuous resources. At this time, the signaling may not carry the field indicating occupied resources/unoccupied resources. I.e. by default as an occupied resource indication.

Second, continuous, or non-continuous, resources that are not configured by the terminal are indicated. At this time, in the resource allocation content under the bandwidth occupied by the indication, a field indicating occupied resources/unoccupied resources needs to be carried. As illustrated in FIG. 4, the base station may indicate unoccupied resources for the terminal, for example, by using the formula according to the case of set 1 (starting point X2 (denoted by S in the formula, e.g., S0), ending point X3 (denoted by S in the formula, e.g., S1)), set 2 (starting point X4 (denoted by S in the formula, e.g., S2), and ending point X5 (denoted by S in the formula, e.g., S3))R can be obtained. The terminal can obtain unoccupied resources according to the r value, and further, the allocated resource position information can be indirectly obtained through occupying the bandwidth and the unoccupied resource condition. Wherein, N is the number of RB/RBG or RE/REG or sub-band/sub-band group; m is the number of the starting point and the ending point corresponding to all the sets.

Further, the allocated resources are indicated in a manner similar to the manner of indication of the allocation of contiguous resources in the existing resource allocation manner. Alternatively, for subcarrier spacing other than 15KHz, an indication subcarrier spacing field needs to be given.

For the above bandwidth indication and the resource allocation indication under the bandwidth, the bandwidth indication and the resource allocation indication under the bandwidth may be carried in one signaling, or may be carried in different signaling respectively to indicate. The different signaling may be physical layer DCI signaling, or higher layer RRC signaling.

In another case, if the bandwidth allocated to the terminal by the base station is smaller, then the base station indicates to configure the occupied resource for the terminal. And further indicates the allocated resource situation to the terminal on the occupied bandwidth. At this time, according to the occupation situation of the resource allocated to the terminal, whether the resource occupation mode is adopted or the non-occupation mode is indicated is selected. For example, in the case that the number of resources allocated to the terminal on the occupied bandwidth is not large (for example, the occupied resources are much smaller than the unoccupied resources), it is preferable to allocate the resources in the occupied resource manner. Otherwise, the same principle is applied. The operation is the same as above.

In another case, the method of the present application or embodiment may be applied to a case where discontinuous resources are allocated to a terminal. Here, a one-to-one list description will not be provided.

The fifth embodiment:

this embodiment provides a resource allocation indication for all scheduled numerology subband cases. The terminal occupies the entire bandwidth and employs different numerologies on different subbands.

Fig. 5 is a schematic diagram of resource allocation with different numerology for different subbands according to an embodiment of the present invention. As shown in fig. 5, the gray diagonal line represents the sub-bandwidth resource with the sub-carrier spacing of f1, the dark gray grid represents the sub-bandwidth resource with the sub-carrier spacing of f2, and the dark gray vertical stripe represents the sub-bandwidth resource with the sub-carrier spacing of f 3. At least one of the plurality of sub-bandwidths may be configured for a terminal. That is, one terminal may configure multiple subbands, and different subbands configure different subcarrier intervals, or multiple terminals may share the entire bandwidth, and different terminals occupy different subbands and adopt different subcarrier intervals.

It is assumed that the entire bandwidth is fully allocated to one terminal, and the terminal configures different subcarrier spacings on different bandwidths. In order to indicate the resource allocation situation on different bandwidths to the terminal, the resource allocation indication mode provided by the invention is still applicable in the scene. The specific mode is as follows:

assume that the base station allocates resource on the bandwidth corresponding to subcarrier f1 for terminal 1. The method for allocating resources comprises at least one of the following steps:

the base station indicates bandwidth information other than the bandwidth corresponding to the f1 subcarrier to terminal 1. The indication mode comprises the following steps: method one, indicating bandwidth sets corresponding to f2 and f 3. Optionally, the bandwidth set may carry subcarrier spacing indications corresponding to f2 and f 3. Method two, indicating subcarrier spacing f1 and f2 corresponding bandwidths, respectively. The bandwidth signaling corresponding to the indications f2 and f3 may also carry resource allocation indication information indicating the bandwidth corresponding to f2 and f3 (for example, may indicate occupied resource indication in the corresponding bandwidth, or unoccupied resource indication). For the first mode, the resource allocation on the bandwidth corresponding to f2 and f3 needs to be further indicated. The indication information may be the same signaling as the signaling indicating the bandwidth, or may be indicated by different signaling. In addition, the terminal 1 obtains bandwidth information allocated by the base station to itself according to the indicated unoccupied bandwidth indication, and further obtains the resource allocation indication in the bandwidth corresponding to f1 in the same signaling or through another received signaling. The resource allocation here may indicate occupied resources or indicate unoccupied resources. In this way, the bandwidths of f1, f2 and f3, respectively, are circumvented, and the large bit overhead caused by the corresponding resource allocation indication at the respective bandwidths is avoided.

It is assumed that the entire bandwidth is fully allocated to multiple terminals (e.g., 3 terminals, f1 for terminal 1, f2 for terminal 2, f3 for terminal 3), and that the terminals configure different subcarrier spacings on different bandwidths. In order to indicate the resource allocation situation on different bandwidths to the terminal, the resource allocation indication mode provided by the invention is still applicable in the scene.

the occupied resource (or bandwidth)/unoccupied resource (or bandwidth) field indicates unoccupied resource (or bandwidth) if the terminal receives the first signaling. The terminal can obtain the position information corresponding to the unoccupied bandwidth or the resource according to the bandwidth indication field.

Further, according to a resource allocation field indicated by the first signaling or the second signaling and/or an occupied resource/unoccupied resource field in a specified bandwidth, the location information of the resource allocation is the resource to be occupied by itself or the resource that cannot be (un) occupied. The signaling of the indication bandwidth information and/or the resource allocation location information under the indication bandwidth may carry the adopted subcarrier spacing of the resource.

However, for resource allocation of the UE2 and the UE3 on the frequency bands corresponding to f2 and f3, respectively, an existing resource allocation manner, e.g., resource information indicating occupation under the corresponding bandwidths, may be adopted.

The occupied bits and/or the manner of resource indication and the type of resource allocation used can all refer to the schemes in embodiments one to four.

Embodiment six:

this embodiment is mainly used to supplement the description of some cases other than the above-described embodiments.

The base station configures a bandwidth mode for the user equipment, where the bandwidth mode indicates occupied bandwidth resources or unoccupied bandwidth resources or complementary resources of the occupied bandwidth resources, except for a predefined, physical layer uplink or downlink DCI signaling and a bandwidth-related designated field in at least one of high-level RRC signaling, such as an occupied bandwidth/unoccupied bandwidth field, or a mode that m bits are introduced into a field for indicating bandwidth resources to indicate occupied bandwidth/unoccupied bandwidth, and the like, the base station may implicitly know that the indicated bandwidth is unoccupied bandwidth and/or a resource mode in a specific DCI format mode. For example, when one of the dcifomat 1A/1B/1D/1C/0A/0B/4A/4B is used to indicate bandwidth and/or resource allocation, the ue may know that the currently indicated resource and/or bandwidth is unoccupied bandwidth and/or resource, or occupied bandwidth and/or resource, by detecting the format. Other DCI format formats for indicating resource allocation are also applicable to the method. Optionally, when the DCI signaling does not carry or indicate occupied bandwidth and/or resource/unoccupied bandwidth and/or resource information, the default base station indicates the occupied bandwidth and/or resource information to the user equipment.

Optionally, for the same user equipment, the same resource configuration pattern may be used on different subbands, for example, the resource occupied configuration pattern used on any subband (that is, information indicating occupied resources to the user equipment by the base station on any subband) or the resource unoccupied configuration pattern used on any subband (that is, information indicating unoccupied resources (resource information occupying a resource complement) to the user equipment by the base station on any subband); alternatively, for the same user equipment, different resource configuration modes may be adopted on different subbands, for example, on a first subband or subband group, the base station indicates the user equipment with information of occupied resources, and on a second subband or subband group, the base station indicates the user equipment with information of unoccupied resources (resource information of occupied resource complement). That is, the base station may flexibly configure the resource allocation manner on the sub-band (i.e., occupied resource allocation or unoccupied resource allocation) for the user equipment on multiple sub-bands.

Optionally, it is further extended that the user equipment determines the sub-band according to a predefined hopping rule over a plurality of sub-bands. Further, the base station may assign the same resource allocation manner or different resource allocation manners (i.e., occupied resource allocation or unoccupied resource allocation) to the ue on the two subbands before and after the hopping. The predefined hopping rule is, for example, sequentially increasing or decreasing according to the subband number, or hopping according to the hopping granularity of M/subbands or RBGs or REGs or RB or RE intervals, or determining the subband to hop each time according to a random number manner (for example, randomly generating a positive integer between [1, d ] to determine the subband, d is the total number of subbands or the total RB/RBG/RE/REG number corresponding to the subband), or other manners.

Alternatively, the same resource allocation pattern may be used for different ues on the same subband. For example, a first user or user group may employ a resource occupied mode or a resource unoccupied mode, and a second user or user group may also employ a resource occupied mode or a resource unoccupied mode. I.e. the occupied/unoccupied resource patterns are shared between user equipments and not user equipment specific; or, for different user equipments, different resource configuration modes may be adopted on the same subband. For example, a first user or user group adopts an occupied resource mode or an unoccupied resource mode, and a second user or user group also adopts an unoccupied resource mode or an unoccupied resource mode. That is, it is not necessary to flexibly configure the indicated resource to be the occupied resource or the unoccupied resource according to the respective resource allocation conditions between the user equipments, so as to reduce the signaling overhead.

Optionally, the signaling for indicating bandwidth configuration may be the same signaling as the signaling for indicating resource allocation under the bandwidth, or may be an independent signaling. For the latter, the base station may actually schedule and/or dynamically change the service, and flexibly configure or indicate the resource allocation condition for the user equipment.

Optionally, the same bandwidth and/or resource allocation mode/manner may be adopted for different cells as well; or different bandwidth and/or resource allocation patterns/manners. Similarly, for different UEs in the same cell, the same bandwidth and/or resource allocation mode/manner may be used; or different bandwidth and/or resource allocation patterns/manners.
