Technical field

The present application relates to the field of communications technologies, and in particular, to a method and apparatus for determining a resource block group size.

Background technique

A Resource Block Group (RBG) is a set of consecutive centralized virtual resource blocks (VRBs). The RBG size indicates the number of VRBs included in each RBG. The virtual resource block may be a physical resource block (PRB), or may be an RB after the PRB performs a specific rule conversion, or may be an RB in a normal sense. In the Long Term Evolution (LTE), the RBG size is a fixed size determined according to the system bandwidth. For example, when the system bandwidth is less than or equal to 10 RBs, the RBG size is 1 RB, that is, one RB is an RBG; When the size is 11 to 26 RBs, the RBG size is 2 RBs, that is, two RBs are one RBG.

With the evolution of communication systems, the fifth generation (5G) new wireless communication system (New Radio, NR) is under study. In 5G NR, the system bandwidth can be 100M, 400M, 500M, etc., and one system bandwidth can be divided into one or more bandwidth parts (Band Width Part, BWP or BP). In order to support different services, different BPs may adopt different frame structure parameters (such as subcarrier spacing and/or CP length, etc.), and use time slots or minislots as scheduling units. However, different frame structures may result in different numbers of RBs in the BP of the same size, and the time domain scheduling resources in the NR can be flexibly scheduled. Therefore, determining the fixed size RBG according to the system bandwidth in LTE cannot meet the requirements of the 5G NR. .

And at least one of a signal transmission feature, a BP information, a channel feature, a system bandwidth information, and a service feature, and directly determine respective RBG sizes.

For example, the implementation process of determining the RBG size by the foregoing network device is exemplified by taking the control channel format information as an example.

First, the correspondence between each control channel format and the RBG size is preset. For example, for DCI format 1a, the RBG size corresponding to it may be preset to be 8 RBs or 6 RBs. For the DCI format 1C, the RBG size can be preset to be any of 8 RBs and 4 RBs. The preset RBG size for DCI format 2C or DCI format 2D may be one of 8 RBs, 6 RBs, 4 RBs, 3 RBs, 2 RBs, and 1 RB.

For example, the implementation process of determining the RBG size by the foregoing network device is exemplified by taking the signal transmission feature as an example.

First, the correspondence between each signal transmission characteristic or signal or channel and the RBG size is preset. For example, the RBG size corresponding to the system information/channel may be preset to be 8 RBs or 6 RBs. The RBG size may be preset to any one of 8 RBs and 4 RBs for the broadcast channel. The preset RBG size is one of 8 RBs, 6 RBs, 4 RBs, 3 RBs, 2 RBs, and 1 RB for a unicast channel or a physical downlink shared channel or a physical uplink shared channel.

Second, the RBG size is determined based on the signal transmission characteristics of the desired scheduling. For example, if the network device determines that the signal transmission characteristic of the required scheduling is system information, it may determine that the RBG size is 8 RBs or 6 RBs. For example, if the network device determines that the signal transmission feature of the scheduled scheduling is a broadcast channel, if the preset RBG size of the broadcast channel is 8 RBs, the network device may determine that the RBG size is 8 RBs, and the preset RBG size of the broadcast channel.

First, the correspondence between each signal transmission characteristic or signal or channel and control channel format and RBG size is preset. For example, for the system information/channel and the control channel format is format 1a, the RBG size corresponding thereto can be preset to be 8 RBs or 6 RBs. For the broadcast channel and the control channel format is format 1a, the RBG size can be preset to be any of 8 RBs and 4 RBs. For a unicast channel or a physical downlink shared channel or a physical uplink shared channel, and the control channel format is format 1a, the preset RBG size is 8 RBs and 6 RBs. For a unicast channel or a physical downlink shared channel or a physical uplink shared channel, and the control channel format is format 2d, the RBG size may be preset to one of 4 RBs, 3 RBs, 2 RBs, and 1 RB.

It can be understood that the RBG size corresponding to the combination of each of the signal transmission features and the control channel format in the embodiment of the present application may be set according to actual conditions, and the foregoing is only an example and is not limited.

Second, the RBG size is determined according to the signal transmission characteristics and control channel formats that are scheduled. For example, if the network device determines that the signal transmission characteristic of the required scheduling is system information and the control channel format is format 1a, the RBG size may be determined to be 8 RBs or 6 RBs. For another example, the network device determines that the signal transmission feature of the scheduled scheduling is a broadcast channel and the control channel format is format 1a, and the network device can determine that the broadcast channel and the control channel format are format 1a and the preset RBG size is 8 RBs. The RBG size is 8 RBs, and the broadcast channel and the control channel format are format 1a. The preset RBG size is 4 RBs, and the network device can determine that the RBG size is 4 RBs. For another example, the network device determines that the signal transmission characteristic of the required scheduling is a unicast channel and the control control channel format is format 1a, and the unicast channel and the control channel format are format 1a, and the preset RBG size is 8 RBs, and the network The device can determine that the RBG size is 8 RBs, and the unicast channel and the control channel format are format 1a. The preset RBG size is 4 RBs, and the network device can determine that the RBG size is 4 RBs. For another example, the network device determines that the signal transmission feature of the scheduled scheduling is a unicast channel and the control control channel format is format 2d, and the unicast channel and the control channel format are format 2d, and the preset RBG size is 4 RBs, and the network The device can determine that the RBG size is 4 RBs, and the unicast channel and the control channel format are format 2d. The preset RBG size is 1 RB, and the network device can determine that the RBG size is 1 RB.

It should be noted that the method for determining the RBG size according to the other information or determining the RBG size according to the combination of other information is similar to the foregoing embodiment, and the specific implementation process is not described herein again.

In the embodiment of the present application, the method for determining the RBG size may be used to determine the corresponding RBG size according to the actual scheduled service requirement, instead of determining the same RBG size for all services under a certain system bandwidth, to a certain extent. Increased flexibility in resource scheduling.

S102: The network device determines that the resource allocated by the terminal is in a subset of the BP where the resource is located.

In the embodiment of the present application, the network device determines that the resource allocated by the terminal is in a subset of the BP where the resource is located, and enables the network device to accurately determine the resource location of the bitmap, thereby accurately allocating resources to the terminal.

In a possible implementation manner, the process for the network device to determine the subset of the BP may be determined in a manner similar to the foregoing determining the RBG size. For example, each control channel information, each signal transmission feature, and each BP may be preset. Each channel characteristic, each system bandwidth information, each service feature, and the like corresponds to a subset of BP, and then the network device can be based on scheduled control channel information, signal transmission characteristics, BP information, channel characteristics, system bandwidth information, and At least one of the business characteristics, etc., directly determines a subset of the respective corresponding BPs.

For example, the implementation process of determining the subset of BP by the foregoing network device is still illustrated by taking the control channel format information as an example.

First, the correspondence between each control channel format and a subset of BP is preset. For example, for DCI format1a, a subset of BPs corresponding thereto can be preset to be the entire BP. The subset of BP that can be preset for DCI format 1C is either 1BP or 1/2BP. A subset of preset BPs such as DCI format 2C or DCI format 2D is one of 1BP, 1/2BP, 1/4BP, and 1/8BP.

It can be understood that, in the embodiment of the present application, a subset of the BPs corresponding to each control channel format may be set according to actual conditions, and the foregoing is only an example and is not limited thereto.

Second, a subset of BP is determined based on the desired control channel format. For example, if the network device determines that the control channel format of the required scheduling is DCI format 1a, then it can be determined that the subset of BP is the entire BP. For another example, if the network device determines that the control channel format of the required scheduling is DCI format 1C, and the subset of the preset BP of the DCI format 1C is 1 BP, the network device can determine that the subset of the BP is the entire BP, and the DCI format 1C is pre- In the case where the subset of BP is set to 1/2 BP, the network device can determine that the subset of BP is 1/2 BP.

In another possible implementation manner, the network device may further determine a size of the subset of the BP according to the size of the RBG. The correspondence between the RBG size and the BP subset may be determined according to the resource requirements of the specific scheduling. For example, the control channel format is still taken as an example. The format of the control channel for the scheduling is DCI format 2C or DCI format 2D. In the case, if the RBG size is 8 RBs, it can be determined that the subset of BP is the entire BP. The RBG size is 4 RBs, and it can be determined that the subset of BP is 1/2 BP. If the RBG size is 2 RBs, it can be determined that the subset of BP is 1/4 BP. The RBG size is 1 RB, and it can be determined that the subset of BP is 1/8 BP, as shown in FIG.

In this embodiment of the present application, the network device may determine one of the RBG size and a subset of the BP in the foregoing manner, and the other may be determined by signaling, for example, by using high layer signaling or physical layer signaling. The way is not limited here. The high-level signaling may be a radio resource control (RRC) signaling or a medium access control (MAC) control element (Control Element, CE) or other signaling, and the specific signaling is not performed here. limited. The physical layer signaling may be downlink control information or the like.

In a possible example, the subset of BPs involved in the foregoing embodiments may include multiple consecutive RBs, and may also include multiple discontinuous RBs. The RBG size is 4 RBs, and the subset of BP is 1/2 BP as an example. FIG. 5 shows a schematic diagram of a subset of BP including a plurality of consecutive RBs. Figure 6 shows a schematic diagram of a subset of BP comprising a plurality of non-contiguous RBs.

The subset of BP in the embodiment of the present application includes a plurality of non-contiguous RBs, which can reduce the occurrence of resource fragments to some extent, and can also improve the diversity gain. For example, when a network device allocates resources, if a subset of BP is a continuous RB, if a small part of resources remain in one subset and a small part of resources remain in another subset, it cannot be different at this time. The resources in the subset are allocated to one terminal, thus causing resource fragmentation. If the subset of BP can be continuous or non-contiguous, when resource allocation is performed, if a small part of resources remain in one subset and a small part of resources remain in the other subset, then no Continuous RBs form a BP subset, so multiple distributed resources can be distributed to one terminal, reducing resource fragmentation. For diversity gain, if the subset of BPs can be non-contiguous RBs, RBs located at different locations can be assigned to one terminal when resource allocation is performed. Different RB channel characteristics at different locations can provide frequency diversity gain and improve communication performance.

In another possible embodiment of the present application, the RBG determined by the network device may include multiple consecutive RBs or multiple non-contiguous RBs. In other words, the RBG may be continuous or non-contiguous.

In the embodiment of the present application, the combination between a continuous or non-contiguous RBG and a subset of continuous or non-contiguous BP may have the following situations:

A: consecutive RBs constitute RBG, and continuous RB/RBG constitutes a subset of BP;

B: consecutive RBs constitute RBG, and non-contiguous RB/RBGs constitute a subset of BP;

C: non-contiguous RBs constitute RBGs, and consecutive RBs/RBGs form a subset of BPs;

D: Non-contiguous RBs constitute RBGs, and non-contiguous RBs/RBGs form a subset of BPs.

Further, if the non-contiguous RBs form an RBG in the embodiment of the present application, one RBG composed of the non-contiguous RBs may be located in a subset of the same BP, or may be located between different subsets of BPs, for example, There may be the following situations:

E: non-contiguous RBs constitute RBGs, consecutive RBs form a subset of BPs, and RBGs are located in a subset of the same BP;

F: non-contiguous RBs constitute RBGs, non-contiguous RBs form a subset of BPs, and RBGs are located in a subset of the same BP;

G: non-contiguous RBs constitute RBGs, consecutive RBs form a subset of BPs, and RBGs are located between subsets of different BPs;

H: Non-contiguous RBs constitute RBGs, non-contiguous RBs form a subset of BPs, and RBGs are located between subsets of different BPs.

The present application describes the various situations involved above in conjunction with practical applications. In the embodiment of the present application, it is assumed that 8 RBs constitute one BP, a subset of BP is 1/2 BP, and 4 RBs in each RBG are taken as an example for description.

FIG. 15 is a schematic diagram of still another subset resource allocation of BP according to an embodiment of the present application. In FIG. 15, a subset of BP includes a first subset of BP and a second subset of BP, and a second subset of BP A subset and a second subset of BP are non-contiguous. In the first subset of non-contiguous BPs, a portion (half) of the RBs in the non-contiguous RBG are located in the first portion of the first subset of the BP, and another portion (the other half) of the RBs in the non-contiguous RBG are located in the BP.

Further, in a possible implementation manner, the combination manner of the RBG size and the subset allocation of the BP in the embodiment of the present application may have multiple implementation manners, for example, including a continuous RB/RBG for the BP subset, and the RBG includes In the case of consecutive RBs, if the RBG size is 1 RB, 2 RBs, and 4 RB cases, the combination of the RBG size and the subset allocation of BP can be as shown in FIG. 16. In this case, the RBG size and BP There are a total of seven combinations of combinations of subset assignments. Similarly, if a similar combination is adopted, for a case where the BP subset includes consecutive RBs/RBGs, and the RBG includes consecutive RBs, if the RBG size is 1 RB, 2 RBs, 4 RBs, and 8 RBs, In the case, there are a total of 15 combinations of combinations of RBG size and BP subset allocation.

For the case where the BP subset includes non-contiguous RB/RBG, and the RBG includes consecutive RBs, if the RBG size is 1 RB, 2 RBs, and 4 RB cases, the RBG size and the subset allocation of the BP are combined, Can be as shown in Figure 17. In Figure 17, there are a total of 14 combinations of combinations of RBG size and subset allocation of BP. Similarly, if a similar combination is adopted, for the case where the BP subset includes consecutive RBs and the RBG includes consecutive RBs, if the RBG size is 1 RB, 2 RBs, 4 RBs, and 8 RBs, There are a total of 30 combinations of combinations of RBG size and BP subset allocation.

In the embodiment of the present application, as shown in FIG. 16 and FIG. 17, the RBG is divided into consecutive RBs in each BP subset to form an RBG size. For example, when the RBG size is 4 RBs, The first 4 RBs of the 8 RBs form one RBG, and the last 4 RBs form one RBG. However, the RBGs in the embodiments of the present application can be non-contiguous, so each RB constituting one RBG can be randomly selected, for example, as shown in FIG. 18.

It can be understood that the interval of the RBs in the foregoing non-contiguous RBG in the embodiment of the present application may be predefined by a protocol, or may be determined by using signaling. The two RBs may be one RBG, or one RB may be one RBG, or may be three RBs. The non-contiguous allocation method may be used, which may be a protocol pre-defined. It can also be determined by means of signaling.

It can be understood that, in the embodiment of the present application, in order to determine a subset of the BPs in which the resources allocated to the terminal are located, the subset information needs to be determined. Specifically, the subset information may include at least one of a size of the subset, a resource partitioning method of the subset, a number of subsets, and scheduling subset information.

The resource partitioning method of the foregoing subset may be multiple. For example, the resource partitioning method of the subset may be determined according to the size of the RBG, or may be predefined, or the network device may notify the terminal by signaling. The specific signaling may be a high layer signal or a physical layer signaling. The high-level signaling may be a radio resource control (RRC) signaling or a medium access control (MAC) control element (Control Element) (CE) or other signaling, which is not limited herein. The physical layer signaling may be downlink control information or the like.

The method for dividing a resource of a specific subset may include dividing a continuous subset and/or dividing a non-contiguous subset.

For continuous subset partitioning, the following method may be included. If BP is to be divided into N subsets, BP may be equally divided into N shares, each of which represents a subset. For example, if one BP includes 20 RBs, the first to fifth RBs are the first subset, the sixth to tenth RBs are the second subset, and the eleventh to fifteenth RBs are the third subset. The subset, the sixteenth to the twentieth RB are the fourth subset.

For non-contiguous subset partitioning, multiple subset partitioning methods can be included. Specifically, the BP may be first divided into a plurality of consecutive parts, and then one or more non-contiguous parts are selected as a subset. Each part includes one or more RB/RBGs. The correspondence between the specific part and the subset may be predefined or signaled. For example, the subset may be first divided into M parts, and M may be predefined or notified, or may be related to the size of the RBG. For example, if the size of the RBG is 8 (or the size of the system's largest RBG or the size of the largest RBG currently available), there may be only one part, only one subset. If the size of the RBG is 4 (or half of the size of the largest RBG of the system or half of the size of the largest RBG currently available), it may be divided into 4 parts, corresponding to 2 subsets. The correspondence between the specific part and the subset may be that the first part and the third part correspond to the first subset, the second part and the fourth part correspond to the second subset; or the correspondence between the part and the subset may be The first part and the fourth part correspond to the first subset, and the second part and the third part correspond to the second subset. The specific correspondence is not limited herein.

For the resource partitioning method of the subset, the BP may be first divided into multiple RBGs, and the current maximum RBG size or the currently available maximum RBG size is divided. For example, if a BP includes 32 RBs and the system has a maximum RBG size of 8 RBs, one BP can be divided into 4 parts, and a subset of BPs is determined according to the actually used RBG size. If the actual RBG size is 8 RBs, the entire BP is a subset. If the actual RBG size is 4 RBs, the BP can be divided into two subsets. The selection of RBs that can be performed in each subset can be implemented in multiple manners, such as several modes in FIG. Among them, in the first method, the first four RBs in each one form the first subset of BP, and the last four RBs in each one constitute the second subset of BP. In the second mode, the first three RBs and the last one RB in each one are formed into a first subset, and the fourth RB to the seventh RB in each one constitute a second subset. In mode 3, the second RB, the fourth RB, the seventh RB, and the eighth RB in each copy constitute the first subset, and the first RB and the third RB in each one are included. The 5th RB and the 6th RB form a second subset. In the fourth method, the first RB, the second RB, the seventh RB, and the eighth RB in each of the first RBs are combined into a first subset, and the third RB and the fourth RB in each one are included. The 5th RB and the 6th RB form a second subset. In the fifth method, the first RB, the third RB, the fifth RB, and the seventh RB in each of the first RBs will be composed, and the second RB and the fourth in each one will be The RB, the sixth RB, and the eighth RB form a second subset. It can be known that the RBs in each subset in the embodiment of the present application can be randomly selected in each one. The positions of the RBs in each of the above methods are consistent, but in actual implementation, the positions of the RBs in each of the same subset may be inconsistent, for example, in the sixth method, the first one may be The first RB, the fifth RB, the sixth RB, and the seventh RB, the first RB, the third RB, the fourth RB, and the fifth RB in the second, in the third The first RB, the fifth RB, the seventh RB, and the eighth RB, and the third RB, the fifth RB, the sixth RB, and the seventh RB in the fourth part constitute the first subset And the second RB, the third RB, the fourth RB, and the eighth RB in the first share, the second RB, the sixth RB, the seventh RB, and the eighth in the second RB, the second RB, the third RB, the fourth RB, and the sixth RB in the third, the first RB, the second RB, the fourth RB, and the eighth in the fourth The RBs form the second subset. Therefore, in the embodiment of the present application, the RBs in each subset are randomly selected, and the positions of the RBs in each of the RBs may be the same or different, and the embodiments of the present application are not exhaustive.

Further, the method for dividing the subset described above may be predefined or signaled.

Optionally, the number of subset partitions may be predefined or may be signaled. Or the number of the subsets may be determined according to the size of the RBG. For example, the number of subset partitions may be a BP bandwidth/RBG size, and the value obtained by rounding up. For example, if a BP includes 32 RBs and the RBG size is 4 RBs, the BP can be divided into 8 subsets. If a BP includes 32 RBs and the RBG size is 2 RBs, the BP can be divided into 16 subsets.

Optionally, which one or which subsets are specifically scheduled may be predefined or signaled. The specific indication method may be an indication of the subset or a bitmap of the indication subset.

For example, the identifier for the indication subset is as follows: If the BP is divided into 8 subsets, each subset is identified by a sequence number, and 1 subset is scheduled, the identifiers of a subset of the 8 subsets may be indicated. For example, with 3 bits, for example, 000 represents the first subset, 001 represents the second subset, 010 represents the third subset, 011 represents the fourth subset, 100 represents the fifth subset, and 101 represents the sixth subset. , 110 represents the seventh subset, and 111 represents the eighth subset.

For example, the bit bitmap for the indication subset is exemplified as follows: divided into 4 subsets, the bit bitmap can be indicated by 4 bits, for example, the first bit represents the first subset, and the second bit represents the second sub- Set, the third bit represents the third subset, and the fourth bit represents the fourth subset. Wherein, the bit value of 0 indicates that the subset is not selected, and the bit value of 1 indicates the selected subset. Of course, the bit value of 0 may indicate the selected subset, and the bit value of 1 indicates that the subset is not selected. If the bit value is 0, the subset is not selected, the bit value is 1 to indicate the selected subset, then 0000 represents no subset; 0001 represents the fourth subset; 0010 represents the third subset; 0100 represents the second subset; Represents the first subset; 0011 represents the third subset and the fourth subset; 1100 represents the first subset and the second subset; 1001 represents the first subset and the fourth subset; 1010 represents the first a subset and a third subset; 0101 represents a second subset and a fourth subset; 0110 represents a second subset and a third subset; 0111 represents a second subset, a third subset, and a fourth subset; 1011 Represents the first subset, the third subset, and the fourth subset; 1110 represents the first subset, the second subset, and the third subset; 1101 represents the first subset, the second subset, and the fourth The subset and the fourth subset; 1111 represents the first subset, the second subset, the third subset, and the fourth subset. Of course, there may be other indication manners in the embodiments of the present application, which are not limited in the embodiments of the present application, and the remaining possibilities are not described herein again.

Alternatively, optionally, the size of the RBG may also be determined according to the indicated subset partitioning method or determined according to information of the currently indicated subset. For example, if the subset is divided into one, the size of the RBG is 8; if the subset is divided into two, the size of the RBG is 4.

In addition, the resource allocation method for the BP aggregation may be indicating the location of the specific BP, and then instructing to continue allocation for the resources on each BP. At the same time, RBG can be cross-BP. Multiple BP resources can also perform resource partitioning of BP subsets uniformly, that is, a subset of BPs can be cross-BP. The specifics are not limited herein.

It is further understood that the step of determining the subset of BP in the step S102 in the embodiment of the present application is an optional step.

S103: The network device determines a resource location of the bit bitmap.

In this embodiment of the present application, the network device may determine a resource location of the bitmap according to the determined RBG size and a subset of the BP.

In the embodiment of the present application, the implementation process of determining the resource location of the bit bitmap by the network device may be implemented by using existing technologies. For example, if the terminal determines that the subset information of the BP is full bandwidth and the RBG size is 8 RBs, the network device may determine that the first bit in the bitmap represents the first RBG, and the second bit represents the second RBG. RBG, and so on, and each RBG contains 8 RBs, except for the last RBG, so it is possible that the total number of RBs is not a multiple of 8.

For another example, if the network device determines that the subset of BP is 1/2 BP and the RBG size is 4 RBs, the network device can determine the meaning of the bits in the bitmap, for example, if the subset of BP is the second subset, That is, the latter half of the resource, the first bit of the bit bitmap represents the first RBG of the latter half of the resource, the second bit represents the second RBG of the latter half of the resource, and so on, and each RBG contains 4 RBs, except for the last RBG, so it is possible that the total number of RBs is not a multiple of four.

S104: The network device allocates resources to the terminal by using the determined RBG size.

In this embodiment of the present application, the network device may allocate resources to the terminal by using the determined RBG size at the resource location corresponding to the determined bit bitmap.

In the embodiment of the present application, the network device adopts the foregoing method for determining the RBG size and the resource scheduling manner, and one or both of the bandwidth portion and the RBG size may be determined according to specific service scheduling requirements, and the scheduling is improved to some extent. flexibility.

The implementation process of determining the RBG size by the network device in the embodiment of the present application may be understood as a method for implicitly determining the RBG size, and may also be determined by using a display mode, such as sending signaling to the network device by other devices. Indicates a specific RBG size, or indicates a resource that the network device needs to schedule, and the scheduled resource has a preset correspondence relationship with the RBG size.

It should be noted that, in the embodiment of the present application, the following implicit manner is determined by using a predefined manner, such as a protocol, and the display mode is determined by using signaling information.

S105: The terminal determines the RBG size.

In the embodiment of the present application, the terminal may determine the RBG size in an implicit manner similar to the network device, and details are not described herein.

In this embodiment, the terminal may also determine the RBG size by using a display manner. In this scenario, the network device may send configuration information or indication information to the terminal.

S106a: The network device sends the first configuration information to the terminal, where the first configuration information includes resource information that has a preset correspondence with the RBG size, for example, control channel information, signal transmission characteristics, BP information, and channel characteristics. At least one of each system bandwidth information and each service characteristic.

S106b: The terminal receives the configuration information sent by the network device, and determines the RBG size according to the configuration information.

In this embodiment, the terminal may preset the RBG size of each control channel information, each signal transmission feature, and each BP. After receiving the configuration information sent by the network device, the terminal has the RBG size included in the configuration information. The RBG size may be directly determined by preset control channel information, signal transmission characteristics, BP information, channel characteristics, system bandwidth information, and service characteristics of the corresponding relationship.

S107a: The network device sends first indication information to the terminal, where the first indication information is used to indicate the size of the RBG.

In the embodiment of the present application, after determining, by using the foregoing manner, the RBG size of the allocated resource, the network device may directly send, to the terminal, first indication information indicating that the allocated resource occupies the RBG size.

S107b: The terminal receives the first indication information sent by the network device, and determines the size of the RBG according to the first indication information.

It can be understood that, in the embodiment of the present application, the implementation manner of determining the RBG size according to the configuration information by the terminal in S105a and S105b, and the implementation manner of determining the RBG size according to the configuration information by the terminal in S106a and S106b may be performed alternatively.

Further, in the embodiment of the present application, the following steps may be further included:

S108: The terminal determines that the resource allocated by the network device is in a subset of the BP where the resource is located, to determine a resource location of the bitmap.

The terminal may determine the subset of the BP implicitly, or determine the size of the subset of the BP according to the size of the RBG, and determine the size of the BP device according to the RBG size. The implementation process of the subset of BP is similar, and will not be described here.

In a possible example, the terminal may also determine a subset of the BP in a display manner. For example, the network device may send the second indication information to the terminal, where the second indication information is used to indicate the subset information of the BP. The terminal receives the second indication information sent by the network device, and according to the second indication information, the subset information of the BP may be determined.

In another possible example, the network device may further send third indication information to the terminal, where the third indication information is used to indicate that the subset of the BP includes consecutive RBs or non-contiguous RBs.

In another possible example, the network device may further send fourth indication information to the terminal, where the fourth indication information is used to indicate that the RBG includes consecutive RBs or non-contiguous RBs.

In the embodiment of the present application, the terminal determines whether the RBG size, the RBG is continuous, the subset of the BP, and the BP subset are consecutive, and at least one of the four processes may be determined in an implicit manner, or at least one of It is determined by the display mode, which is not limited in the embodiment of the present application.

The first indicator information, the second indication information, the third indication information, and the fourth indication information may be used by the terminal to determine whether the RBG size, the RBG is continuous, and the subset of the BPs are displayed in the display mode. The network device respectively indicates to the terminal, and at least two of the four indication information may also be jointly indicated. In a possible embodiment, the network device may jointly indicate the first indication information, the second indication information, the third indication information, and the fourth indication information by using the same cell information.

In a possible implementation, in the embodiment of the present application, the indication of the resource allocation of the BP may be implemented by using a bit in the protocol header of the bit bitmap to indicate a bit bitmap, or a subset of the BP may be indicated by a bit. The way to allocate an index implements an indication of the resource allocation of the BP.

The following describes the indication process of various BP resource allocation situations in combination with actual applications.

In the embodiment of the present application, one bit in the protocol header of the bit bitmap may be used to indicate whether the subset of the currently scheduled BP is continuous or non-contiguous, for example, bit 0 represents continuous, and bit 1 represents discontinuity. When the bit value is 1, it indicates that the non-contiguous RBs form a subset of BPs, wherein the method in which the non-contiguous RBs form a subset of BPs may be protocol pre-defined or configured by signaling, for example, by radio resource control (Radio Resource) Control, RRC) signaling configuration.

In the embodiment of the present application, three bits may also be used to indicate whether a subset of the BP and the RBG are consecutive, for example, whether the first bit indication is the first subset of BP or the second subset of BP, and the second The bit indication indicates whether four consecutive RBs are one RBG, or that the non-contiguous (such as two intervals) RB is one RBG. For example, if the resource allocation mode of the first subset of BP is a non-contiguous RBG of the first subset of BP, the resource allocation mode of the second subset of BP is a continuous RBG of the second subset of BP. If the first bit takes a value of 0, it represents the first subset of BP; the first bit takes a value of 1, representing the second subset of BP. If the second bit takes a value of 0, it represents a continuous RBG; the second bit takes a value of 1, representing a non-contiguous RBG. Then the allocation of the first subset of BP is 01, and the allocation of the second subset of BP is 10. (The bit value is vice versa).

Further, the size of the RBG may be separately indicated. For example, if one RB, two RBs, four RBs, and eight RBs are supported, two bits are used to indicate the size of the specific RBG, or other values are This is not limited.

In this embodiment of the present application, the subset of the BP and the RBG may be jointly and jointly indicated, and the RBG size is separately indicated. such as:

00: the first subset of BP, continuous RBG; 01: the first subset of BP, non-contiguous RBG

10: The second subset of BP, continuous RBG; 11: The second subset of BP, non-contiguous RBG.

Of course, the meaning of other bit values is also possible, just for example.

In this embodiment of the present application, two bits may also be used to indicate whether it is the first subset of BP or the second subset of BP, whether the subset of BP is discontinuous and whether the RBG is continuous. such as:

00: the first subset of BP, continuous RBG;

01: the second subset of BP, continuous RBG;

10: a subset of discontinuous BP, non-contiguous RBG, the first subset of BP;

11: A subset of discontinuous BP, a non-contiguous RBG, and a second subset of BP.

or:

10: a subset of discontinuous BP, continuous RBG, the first subset of BP;

11: A subset of discontinuous BP, continuous RBG, second subset of BP.

or:

00: the first subset of BP, continuous RBG;

01: the second subset of BP, continuous RBG;

10: a subset of discontinuous BP, non-contiguous RBG, the first subset of BP;

11: A subset of discontinuous BP, a non-contiguous RBG, and a second subset of BP.

In this embodiment of the present application, it is also possible to use 3 bits to indicate whether it is the first subset of BP or the second subset of BP, whether the subset of BP is non-contiguous and whether the RBG is continuous. such as:

000: the first subset of BP, continuous RBG;

001: the second subset of BP, continuous RBG;

010: a subset of discontinuous BP, non-contiguous RBG, the first subset of BP;

011: a subset of discontinuous BP, a non-contiguous RBG, and a second subset of BP;

101: a subset of discontinuous BP, continuous RBG, first subset of BP;

110: A subset of discontinuous BP, a continuous RBG, and a second subset of BP.

Of course, the meaning of other bit values is also possible, just for example.

Further, in the embodiment of the present application, the combination of the RBG size and the subset allocation of the BP may be indicated by the bit in the protocol header of the bit bitmap. For the combination mode shown in FIG. 16, if the RBG size and BP are correctly indicated. For subset allocation, 3 bits are required for indication. For the combination shown in FIG. 17, if the RBG size and the subset allocation of BP are correctly indicated, four bits are required for indication.

Through the above embodiments, a subset design of discontinuous bandwidth portions is designed, which can support subset resource allocation of non-contiguous bandwidth parts, avoid resource fragmentation, and obtain frequency diversity gain and improve transmission performance.

In the foregoing embodiment of the present application, there are many types of RBGs. If the network device and the terminal determine the RBG size for each RBG size, a large signaling overhead is caused. In order to reduce signaling overhead, the network device may determine a set of RBG sizes, include at least one RBG size in the set of RBG sizes, and determine a required scheduled RBG size in the set to reduce signaling. Overhead. For example, if there are 8 RBG sizes available, three bits are needed to indicate the RBG size, and if a set of RBG sizes can be determined first, the RBG size of the part is included in the set. For example, if it is determined that a set includes 2 RBG sizes, only one bit is needed to indicate which one of the specific sets is used; if it is determined that one set includes 4 RBG sizes, only two bits are needed to indicate the specific use in the set. Which RBG size is OK. Therefore, the signaling overhead can be reduced by adopting a method of determining a set of RBG sizes.

FIG. 20 is a flowchart of another method for determining an RBG size according to an embodiment of the present application. Referring to FIG. 20, the method includes:

S201: The network device determines a set of RBG sizes.

In the embodiment of the present application, the determining the set of the RBG size includes determining the number of the RBG size and the specific value of the RBG size included in the set, for example, determining the RBG size set includes two types of values, where the two values are respectively It is 8 RBs and 4 RBs. A set can include one or more RBG sizes.

The network device may determine the set of RBG sizes according to at least one of control channel information, signal transmission characteristics, and BP information, channel characteristics, system bandwidth information, and service characteristics. For example, the network device can determine a set of RBG sizes based on at least one of a control channel format, control channel content, and scrambling information for the control channel. The network device may also determine a set of RBG sizes based on the information that the allocated resources use for the bearer. The information includes system information, broadcast information, cell level information, public information, user-specific information, and group information. The network device may also determine a set of RBG sizes based on information of the bandwidth portion BP in which the allocated resources are located. The information of the BP includes at least one of the following: bandwidth information of the bandwidth portion, carrier frequency information of the bandwidth portion, and frame structure information of the bandwidth portion.

In the embodiment of the present application, a set of RBG sizes corresponding to each control channel information, each signal transmission feature, each BP, each channel feature, each system bandwidth information, and each service feature may be preset, and then the network device may be controlled according to scheduling. The channel information, the signal transmission characteristics, the information of the BP, the characteristics of each channel, the bandwidth information of each system, and at least one of each service feature, directly determine a set of respective RBG sizes. System bandwidth information can be understood as bandwidth information of system bandwidth, carrier frequency information of system bandwidth, and frame structure information of system bandwidth. The carrier frequency information and frame structure information are understood as above.

The service feature can be understood as at least one of a mobile broadband service, a low-latency service, a high-reliability service, a video service, a voice service, a real-time service, a short message service, and a low-latency and high-reliability service. The channel feature can be understood as a feature of the network device using the determined RBG size allocated resources for carrying information, such as transmit diversity transmission, spatial multiplexing transmission, open loop transmission, closed transmission, wide beam transmission, narrow beam transmission, and single. At least one of streaming, multi-stream transmission, single-cell transmission, multi-point coordinated transmission, and the like.

For example, the correspondence between the control channel format and the set of RBG sizes may be preset in the embodiment of the present application. For example, the set of RBG sizes corresponding to the DCI format 1a may be preset to include one RBG size, and the one RBG size is 8 RBs. The set of RBG sizes corresponding to the DCI format 1C may be preset to include two RBG sizes, and the two RBG sizes are 8 RBs and 4 RBs, respectively. For the DCI format 2C or the DCI format 2D, the preset RBG size of the preset and the corresponding RBG size includes 4 RBG sizes, and the 4 RBG sizes are 8 RBs, 4 RBs, 2 RBs, and 1 respectively. RB.

It is to be understood that the RBG size set corresponding to each control channel format in the embodiment of the present application may be set according to actual conditions, and the foregoing is only an example and is not limited thereto. When determining the set of RBG sizes, the network device may determine the set of RBG sizes according to the control channel format that needs to be scheduled. For example, if the network device determines that the control channel format to be scheduled is DCI format 1a, it may be determined that the set of RBG sizes includes 1 RBG size, and the 1 RBG size is 8 RBs. For example, if the network device determines that the control channel format to be scheduled is DCI format 1C, it may be determined that the RBG size set includes two RBG sizes, and the two RBG sizes are 8 RBs and 4 RBs, respectively.

In the embodiment of the present application, the implementation manner of determining the RBG size set is similar to the foregoing implementation manner for determining the specific RBG size. Therefore, refer to the foregoing related description, and details are not described herein again.

S202: The network device determines a size of the first RBG in the set of RBG sizes.

In this embodiment of the present application, the network device may determine the RBG size to be scheduled in the determined RBG size set according to the resource scheduling situation. For example, in a case where the remaining resources to be allocated are relatively concentrated or continuous or relatively large, an RBG size with a relatively large RBG size may be selected in the determined RBG size set, and the remaining resources to be allocated are dispersed or discrete or less. In the case of the RBG size set, the RBG size with a smaller RBG size value may be selected.

In the embodiment of the present application, for convenience of description, the RBG size determined in the set of RBG sizes is distinguished, and the RBG size determined directly by using the manner involved in the foregoing embodiment, and the RBG size determined in the set of RBG sizes is called For the first RBG size.

S203: The network device allocates resources to the terminal by using the determined first RBG size.

In the embodiment of the present application, the set of the corresponding RBG size may be determined according to the actual scheduled service requirement, and the RBG size set may include one or more RBG sizes, which improves the flexibility of resource scheduling to some extent.

S204: The terminal determines a set of RBG sizes.

In the embodiment of the present application, the terminal may also determine a set of RBG sizes implicitly, and determine a first RBG size in the set, and determine, according to the first RBG size, the network device as described in the network device. The resources allocated by the terminal are not described here.

In the embodiment of the present application, the terminal may further determine the size of the first RBG in the set by using a display manner. For example, on the basis of the foregoing FIG. 20, the terminal may further include the following steps:

S205: The network device sends indication information and/or configuration information to the terminal.

The indication information is used to indicate the size of the first RBG. The configuration information is used to indicate a set of RBG sizes.

When the network device sends only the indication information to the terminal, the configuration information may not be sent, and the terminal device may determine the set of the RBG size by using an implicit method. The specific method is similar to the method determined by the network device, and details are not described herein. At this time, the indication information only indicates the RBG size in the set of RBG sizes. Signaling overhead can be reduced.

When the network device sends only the configuration information to the terminal, the indication information may not be sent, and the terminal device may determine the RBG size by using an implicit method. The specific method is similar to the method determined by the network device, and details are not described herein. Signaling overhead can be reduced.

S206: The terminal receives the indication information and/or the configuration information sent by the network device.

The terminal determines, according to the indication information, a size of the first RBG in the set. And/or, the terminal determines a set of RBG sizes according to the configuration information.

In the embodiment of the present application, the terminal determines the implementation manner of the first RBG size by receiving the indication information and/or the configuration information sent by the network device, which may save signaling overhead to some extent. For example, the indication information or configuration information may be sent to the terminal through high layer signaling (such as RRC signaling) or physical layer information (such as DCI signaling). The indication information and the configuration information may use the same signaling or different signaling, for example, the configuration information adopts high layer signaling, and the indication information uses physical layer signaling. The high-level signaling may be system-level or cell-level signaling, or may be user-level signaling, which is not limited herein.

S207: The terminal determines, according to the first RBG size, a resource allocated by the network device for the terminal.

In the embodiment of the present application, the terminal determines the implementation manner of the first RBG size by receiving the configuration information and the indication information sent by the network device, and the configuration information is sent to the terminal through the RRC signaling, and the indication information is sent to the terminal through the DCI. The configuration information is carried in the DCI, so the DCI signaling overhead can be saved to some extent.

Further, in the embodiment of the present application, the network device and the terminal may further determine a subset of the BP in which the resource allocated by the network device is located, where the network device and the terminal determine a specific implementation of the subset of the BP in which the resource allocated by the network device is located. For the manner, refer to the related descriptions in the foregoing embodiments, and details are not described herein again.

Further, in the embodiment of the present application, the subset of the BP may include multiple consecutive or non-contiguous RBs, and/or the RBG includes multiple consecutive or non-contiguous RBs. For the specific implementation process, refer to the foregoing embodiment. The related description is not repeated here.

In the above embodiment, the network device or terminal may determine a set of RBG sizes based on the information of the BP. The information of the BP may include at least one of the following information: bandwidth information of the BP, carrier frequency information of the BP, and frame structure information of the BP.

Hereinafter, a method of determining a set of RBG sizes will be described by taking a set of RBG sizes according to bandwidth information of BP as an example.

The terminal or the network device stores a correspondence between a bandwidth of the BP and a set of RBG sizes, wherein the bandwidth of the BP may be represented by the number of resource blocks (RBs). The correspondence relationship is, for example, a correspondence between a BP-sized interval and a set of RBG sizes. It may also be a correspondence between a BP-sized interval and an RBG size. In this case, it can be understood that the set of RBG sizes has only one value.

For example, the mapping between the BP-sized interval and the RBG-sized set of the terminal or the network device is used as an example. In this case, determining the set of the RBG size according to the bandwidth information of the BP may include the following steps, and may be performed by the terminal or the network device:

Determining a section of the first BP size according to the bandwidth information of the BP;

Determining a set of RBG sizes corresponding to the interval of the first BP size, or determining a size of the RBG corresponding to the interval of the first BP size.

The interval of the first BP size is the interval in which the size of the BP is located, and the size of the BP is the bandwidth of the BP, which may be in units of RBs. The size of the BP can be determined according to the bandwidth information of the BP, and the interval including the size of the BP is found in the interval of the BP size stored in the terminal or the network device, that is, the interval of the first BP size.

The correspondence may be presented in the form of a table, or may be presented in other manners. The embodiment of the present application does not limit its representation, as long as it can reflect the correspondence between the bandwidth of BP and the set of RBG sizes, such as BP size. The correspondence between the interval and the set of RBG sizes.

The following uses a table as an example to describe the implementation of a correspondence. Please refer to Table 1, which shows a correspondence between a BP size and a set of RBG sizes. Among them, the BP size interval is represented by the range of the number of RBs. P represents the size of the RBG, and the unit is also the number of RBs.

Table 1

In Table 1 above, each BP-sized interval may correspond to two configured RBG sizes, such as Configuration 1 and Configuration 2. There can be a value of RBG size in each configuration. The values of the RBG sizes corresponding to the two configurations constitute a set of RBG sizes. The network device may send the information of the configuration 1 or the configuration 2 as the indication information to the terminal, and the terminal determines the size of the first RBG in the foregoing embodiment according to the indication information. The information of configuration 1 is used to indicate that the terminal adopts the RBG size of configuration 1. The information of configuration 2 is used to indicate that the terminal adopts the RBG size of configuration 2.

The interval division of the BP size is described below in conjunction with a table. The BP bandwidth in the following table is in RB, that is, the size of the BP bandwidth can also be referred to as BP size. "-" stands for "to", for example "36-72" means "36 to 72".

Please refer to Table 2, which gives an example of interval division of BP size.

Table 2

BP bandwidth (in RB) <36 36-72 73-144

145-273

The boundary values between different intervals in the above table may be located in an interval smaller than the boundary value, or may be located in an interval larger than the boundary value. For example, in Table 2, 36 is located in the interval "36-72"; in another example, 36 may be located in the interval "≤36". Other boundary values are similar. The boundary values in the table below can also be treated the same.

The above 36 may be referred to as a first boundary value, 72 or 73 as a second boundary value, 144 or 145 as a third boundary value, and 273 as a fourth boundary value. Where 36 can be replaced by 35 or 37, then the first boundary value can take a value in [35, 36, 37]. 72 can be replaced by any of 69-71, and correspondingly, 73 can be replaced by any of 70-72, and the second boundary value can take a value of 69-72 or 70-73. 144 may be replaced by any of 137-143, and correspondingly, 145 may be replaced by any of 138-144, and the third boundary value may take a value of 137-144 or 138-145. The fourth boundary value is the maximum bandwidth of BP, such as 273 RBs or 275 RBs. For example, Table 3 gives an example of another BP partition.

table 3

BP bandwidth (in RB) <37 37-72 73-144 145-275

The interval of BP size considers all the values in the maximum bandwidth of BP, so that each value can find the corresponding interval. And this interval is unique, that is, there is no overlapping area between different intervals. In addition, the last interval maximum value is the value of the BP maximum bandwidth.

The above division method considers the overhead of control information when resource allocation is performed for each size of BP. In order to make the resource allocation of each size BP, the overhead of the control information is as balanced as possible, that is, the overhead is as close as possible, and the above division manner is designed. Of course, the above division example is only an example. Under the principle that the overhead is as close as possible, other division manners should also be within the protection scope of the present application. The control information may be, for example, downlink control information (DCI).

The maximum bandwidth of BP is 273 or 275, and the size of RB RBG is selected from [2, 4, 8, 16] as an example. If the size of the RBG is 16 RBs, then for 273 or 275 RBs, 18 bits are required to indicate the resources allocated in the BP (the resources are allocated, for example, in RBG granularity).

Taking 18 bits as an example, assuming that the maximum number of bits in each interval is 18, when the RBG size is 8, the maximum 8*18 RBs, that is, 144 RBs can be supported. If the RBG size is 4, 4* can be supported. 18=72 RBs; if the RBG size is 2, it can support a maximum of 2*18 RBs, that is, 36 RBs. Thus, the BP division of Table 2 or Table 3, or any alternative thereof, is devised.

The maximum value of each interval may be less than the maximum number of RBs calculated by the corresponding RBG size by X RBs, and X is the corresponding RBG size. Therefore, the first boundary value may take a value in [35, 36, 37]; the second boundary value may take a value in 69-72 or 70-73; the third boundary value may be in 137-144 or Take a value from 138-145.

Please refer to Table 4, which gives an example of another BP-sized interval partition.

Table 4

BP bandwidth (in RB) <17 17-40 41-112 113-273

The boundary values between different intervals in the above table may be located in an interval smaller than the boundary value, or may be located in an interval larger than the boundary value.

The above 17 may be referred to as a first boundary value, 40 or 41 as a second boundary value, 112 or 113 as a third boundary value, and 273 as a fourth boundary value. Where 17 can be replaced by 16, then the first boundary value can take a value in [16, 17]. 40 can be replaced by any of 37-39, and correspondingly, 41 can be replaced by any of 38-40, and the second boundary value can take a value of 37-40 or 38-41. 112 may be replaced by any of 105-111, and correspondingly, 113 may be replaced by any of 106-112, and the third boundary value may take a value of 105-112 or 106-113. The fourth boundary value is the maximum bandwidth of BP, such as 273 RBs or 275 RBs.

In the embodiment corresponding to Table 2 or Table 3, the interval division of the BP size considers the principle that the control information overhead is as close as possible when the BPs of different sizes perform resource allocation. In the present embodiment, the principle that the smaller the BP bandwidth is, the smaller the control information overhead is considered. The control information can be, for example, DCI.

In one design, the number of bits of control information is designed to be a plurality of different values, each of which may correspond to a BP-sized interval. For example, the number of bits of control information can be designed to be 4-6 values. Further, these values can be selected, for example, from [8, 10, 12, 14, 16, 18].

Please refer to Table 5, which gives an example of another BP-sized interval partition.

table 5

BP bandwidth (in RB) <68 68-136 137-204 205-273

The boundary values between different intervals in the above table may be located in an interval smaller than the boundary value, or may be located in an interval larger than the boundary value.

In this embodiment, the principle that the interval of the BP size is divided as evenly as possible is considered. Similarly, taking 1-273 or 275 RBs as an example, if divided into 4 intervals, each interval may include 273/4=68.25 RBs or 275/4=68.75 RBs.

The calculation result is only a quantity of reference values. Optionally, each section may include any number of RBs of 65-75. In addition, the divided sections may include the same number of RBs. The above table takes 68 RB or 69 RB as an example.

The above 68 may be referred to as a first boundary value, 136 or 137 as a second boundary value, 204 or 205 as a third boundary value, and 273 as a fourth boundary value. The first boundary value can take a value of 65-75. The second boundary value may be increased by N1 RBs based on the first boundary value, wherein N1 may take a value of 65-75. The third boundary value may be increased by N2 RBs based on the second boundary value, wherein N2 may take a value of 65-75. The fourth boundary value is the maximum bandwidth of BP, such as 273 RBs or 275 RBs. For example, Table 6 gives an example of another BP-sized interval partition.

Table 6

BP bandwidth (in RB) <69 69-138 139-206 207-275

The above description is based on the example of dividing the interval of four BP sizes. However, it is not intended to limit the present application. The BP-sized interval may be divided into five levels, that is, divided into five BP-sized intervals. Also consider the principle of dividing the BP size interval as evenly as possible. Also taking 1-273 or 275 RBs as an example. In this case, each interval may include 273/5=54.6 RBs or 273/5=55 RBs.

The calculation result is only a quantity of reference values. Optionally, each interval may include any number of RBs of 50-60. In addition, the divided intervals may include the same or different RB numbers. For example, 54 RBs or 55 RBs. An example of interval division of an RB size is given in Table 7.

Table 7

BP bandwidth (in RB) <55 55-110 111-165 166-220 221-273

The boundary values between different intervals in the above table may be located in an interval smaller than the boundary value, or may be located in an interval larger than the boundary value.

The above 55 may be referred to as a first boundary value, 110 or 111 as a second boundary value, 165 or 166 as a third boundary value, 220 or 221 as a fourth boundary value, and 273 as a fifth boundary value. The first boundary value can take a value of 50-60. The second boundary value may add M1 RBs based on the first boundary value, wherein M1 may take a value of 50-60. The third boundary value may add M2 RBs based on the second boundary value, where M2 may take a value of 50-60. The fourth boundary value may add M3 RBs based on the third boundary value, wherein M3 may take a value of 50-60. The fifth boundary value is the maximum bandwidth of BP, such as 273 RBs or 275 RBs. For example, Table 8 gives an example of another BP-sized interval partition.

Table 8

BP bandwidth (in RB) <56 56-112 113-166

167-222 223-275

By analogy, it can be divided into 6 BP-sized intervals, also taking 1-273 or 275 RBs as an example. In this case, each interval can include 273/6=45.5 RBs or 275/6=45.83 RBs.

The calculation result is only a quantity of reference values. Optionally, each section may include any number of RBs of 40-50. In addition, the divided sections may include the same number of RBs. For example, 45 RBs or 46 RBs. An example of interval division of an RB size is given in Table 9.

Table 9

BP bandwidth (in RB) <45 45-90 91-136 137-182 183-228 229-273

The boundary values between different intervals in the above table may be located in an interval smaller than the boundary value, or may be located in an interval larger than the boundary value.

The above 45 may be referred to as a first boundary value, 90 or 91 as a second boundary value, 136 or 137 as a third boundary value, 182 or 183 as a fourth boundary value, and 228 or 229 as a fifth boundary value. , 273 is called the sixth boundary value. The first boundary value can take a value of 40-50. The second boundary value may add L1 RBs based on the first boundary value, wherein L1 may take a value of 40-50. The third boundary value may add L2 RBs based on the second boundary value, wherein L2 may take a value of 40-50. The fourth boundary value may add L3 RBs based on the third boundary value, wherein L3 may take a value of 40-50. The fifth boundary value may add L4 RBs based on the fourth boundary value, wherein L4 may take a value of 40-50. The sixth boundary value is the maximum bandwidth of BP, such as 273 RBs or 275 RBs. For example, Table 10 gives an example of another BP-sized interval partition.

Table 10

BP bandwidth (in RB) <46 46-91 92-138 139-184 185-230 231-275

Please refer to Table 11, which gives an example of another BP-sized interval partition.

Table 11

BP bandwidth (in RB) <61 61-100 101-150 151-200 201-275

The division method considers the interval division of the BP size measured by channel state information (CSI), so that the data scheduling and the CSI measurement have the same BP-sized interval division, thereby improving the performance of data transmission.

The above examples of various BP-sized interval divisions are merely examples and are not intended to limit the application. After the interval division of the BP size is determined, the set of RBG sizes is determined according to the bandwidth information of the BP, and can be determined according to the correspondence relationship shown in Table 1. The set of RBG sizes may include two RBG sizes, corresponding to configuration 1 and configuration 2 in the table, respectively. Table 1 can be modified to other forms, such as the form shown in Table 12, where X ₀ , X ₁ , ..., Xmax is the boundary value of the interval of each BP size, and Xmax is the maximum bandwidth of BP.

Table 12

Considering the overhead of control information, it can be designed that the larger the bandwidth of BP (ie, the larger the size of BP), the larger the RBG size. The BP-sized interval in Table 1 or 12 is ranked according to the reference BP bandwidth (for example, the maximum or minimum BP bandwidth) in the interval.
