Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a communication method and device. Background Art

[0003] In a communication system, when a bandwidth part (BWP) is used for physical downlink shared channel (PDSCH) transmission between a network device and a terminal device, the terminal device can assume that several consecutive physical resource blocks (PRBs) use the same precoding matrix, where several consecutive PRBs are called a physical resource block group (PRG). This technology is called physical resource block bundling (PRB bundling).

[0004] In the future, it is possible to package multiple discrete frequency domain resources (such as multiple carriers) into an integrated single cell. In this case, how the terminal device determines the resource group (such as PRG) is still an issue to be studied. Summary of the Invention

[0005] The embodiments of the present application provide a communication method and apparatus, which enable a terminal device to determine a resource group in a scenario where multiple discrete frequency domain resources are packaged and integrated into a single cell, thereby reducing the power consumption of the terminal device.

[0006] In a first aspect, an embodiment of the present application provides a communication method that can be performed by a terminal device, where the terminal device may refer to the terminal device itself or to a processor, module, chip, or chip system in the terminal device that implements the method. In this method, the terminal device receives configuration information, where the configuration information is used to configure a resource block bundling size corresponding to each second frequency domain resource in a plurality of second frequency domain resources of a first frequency domain resource, where the resource blocks between different second frequency domain resources in the plurality of second frequency domain resources are discontinuous and the resource blocks of each second frequency domain resource are contiguous; and the terminal device determines a resource group corresponding to each second frequency domain resource based on the resource block bundling size corresponding to each second frequency domain resource.

[0007] It can be seen that in the embodiment of the present application, the first frequency domain resource includes multiple second frequency domain resources, and the resource blocks between different second frequency domain resources in the multiple second frequency domain resources are discontinuous, but the resource blocks of each second frequency domain resource are continuous. Then, the multiple discrete second frequency domain resources are packaged and integrated into a single cell corresponding to the first frequency domain resource. In this scenario, the terminal device can determine the resource group corresponding to each second frequency domain resource based on the resource block binding size corresponding to each configured second frequency domain resource, and then the terminal device can perform resource block binding for each second frequency domain resource, which can reduce the power consumption of the terminal device.

[0008] In an optional implementation, the first frequency domain resource is a bandwidth part (BWP), the second frequency domain resource is a carrier, the resource block is a physical resource block (PRB), the resource block bundling size is a physical resource block (PRB) bundling size, and the resource group is a physical resource block group (PRG). This shows that multiple discrete carriers can be packaged and integrated into a single cell corresponding to the BWP.

[0009] In one optional implementation, the resource block bundle size corresponding to each second frequency domain resource is the same, and the resource group corresponding to each second frequency domain resource includes M resource blocks, where M resource blocks are the resource blocks occupied by the second frequency domain resource, and M is a positive integer. Alternatively, it can be understood that when the resource block bundle size corresponding to each second frequency domain resource is the same, the size of the resource group corresponding to each second frequency domain resource is M.

[0010] It can be seen that when the resource block binding size corresponding to each second frequency domain resource is the same, the terminal device can determine that the resource group corresponding to each second frequency domain resource includes the M resource blocks occupied by the second frequency domain resource group itself.

[0011] Optionally, when the resource block bundles corresponding to each second frequency domain resource are of the same size and are all configured as broadband, the resource group corresponding to each second frequency domain resource includes M resource blocks. Alternatively, it can be understood that when the resource block bundles corresponding to each second frequency domain resource are of the same size and are all configured as broadband, the size of the resource group corresponding to each second frequency domain resource is M.

[0012] In another optional implementation, the resource block binding size corresponding to each second frequency domain resource is the same, and for the nth second frequency domain resource among the multiple second frequency domain resources: the size of the first resource group of the nth second frequency domain resource is P′-N start,n modP′; if (N start,n +N size,n )mod P′≠0, the size of the last resource group of the nth second frequency domain resource is (N start,n +N size,n )mod P′;if (N start,n +N size,n)mod P′=0, the size of the last resource group of the nth second frequency domain resource is P′. start,n is the starting number of the resource block in the nth second frequency domain resource, N size,n is the number of resource blocks included in the nth second frequency domain resource, P′ is the resource block bundling size corresponding to multiple second frequency domain resources, mod is the remainder function, and P′ and n are positive integers.

[0013] It can be seen that when the resource block bundling size corresponding to each second frequency domain resource is the same, for the nth second frequency domain resource among the multiple second frequency domain resources, the terminal device can determine the size of the first resource group and the last resource group corresponding to the nth second frequency domain resource based on the resource block bundling size corresponding to the multiple second frequency domain resources, the starting number of the resource block in the nth second frequency domain resource, and the number of resource blocks included in the nth second frequency domain resource. In addition, the size of the other resource groups corresponding to the nth second frequency domain resource is all P′.

[0014] In an optional implementation, P′ is determined based on one of the following: the sum of the bandwidths of the multiple second frequency domain resources, the maximum frequency domain interval of the multiple second frequency domain resources, or the minimum frequency domain interval of the multiple second frequency domain resources.

[0015] In another optional implementation, the resource block bundling size corresponding to each second frequency domain resource is different, and the resource group corresponding to the nth second frequency domain resource among the multiple second frequency domain resources includes M resource blocks, where M resource blocks are the resource blocks occupied by the second frequency domain resource, and M and n are positive integers. Alternatively, it can be understood that the resource block bundling size corresponding to each second frequency domain resource is different, and the size of the resource group corresponding to the nth second frequency domain resource among the multiple second frequency domain resources is M.

[0016] It can be seen that when the resource block binding size corresponding to each second frequency domain resource is different, for the nth second frequency domain resource among multiple second frequency domain resources, the terminal device can determine that the resource group corresponding to the nth second frequency domain resource includes the M resource blocks occupied by itself.

[0017] Optionally, the resource block binding size corresponding to each second frequency domain resource is different, and when the resource block binding size corresponding to the nth second frequency domain resource among multiple second frequency domain resources is configured as broadband, the resource group corresponding to the nth second frequency domain resource includes M resource blocks occupied by itself.

[0018] In another optional implementation, the resource block binding size corresponding to each second frequency domain resource is different. For the nth second frequency domain resource among the multiple second frequency domain resources: the size of the first resource group of the nth second frequency domain resource is P′ n -N start,n modP′ n; If (N start,n +N size,n )modP′ n ≠0, the size of the last resource group of the nth second frequency domain resource is (N start,n +N size,n )modP′ n ; If (N start,n +N size,n )modP′ n = 0, the size of the last resource group of the nth second frequency domain resource is P′ n Among them, N start,n is the starting number of the resource block in the nth second frequency domain resource, N size,n is the number of resource blocks included in the nth second frequency domain resource, P′ n is the resource block binding size corresponding to the nth second frequency domain resource, mod is the remainder function, P′ n and n are positive integers.

[0019] It can be seen that when the resource block binding size corresponding to each second frequency domain resource is different, for the nth second frequency domain resource among multiple second frequency domain resources, the terminal device can determine the size of the first resource group and the last resource group corresponding to the nth second frequency domain resource based on the resource block binding size corresponding to the nth second frequency domain resource, the starting number of the resource block in the nth second frequency domain resource, and the number of resource blocks included in the nth second frequency domain resource. In addition, the sizes of other resource groups corresponding to the nth second frequency domain resource are all P′ n .

[0020] In an optional embodiment, P′ n It is determined based on the bandwidth or frequency domain interval of the nth second frequency domain resource.

[0021] In an optional implementation, different resource groups use different precoding matrices. Therefore, the terminal device may assume that the network device uses different precoding matrices when using frequency domain resources in different resource groups for data transmission.

[0022] In a second aspect, an embodiment of the present application provides a communication method that can be performed by a network device, where the network device may refer to the network device itself, or to a processor, module, chip, or chip system in the network device that implements the method. In this method, the network device sends first configuration information, where the configuration information is used to configure a resource block bundling size corresponding to each of multiple second frequency domain resources in a first frequency domain resource, where the resource blocks between different second frequency domain resources in the second frequency domain resource are discontinuous and the resource blocks of each second frequency domain resource are contiguous, and the resource block bundling size corresponding to each second frequency domain resource is used to determine a resource group corresponding to the second frequency domain resource.

[0023] It can be seen that in the embodiment of the present application, the first frequency domain resource includes multiple second frequency domain resources, and the resource blocks between different second frequency domain resources in the multiple second frequency domain resources are discontinuous and the resource blocks of each second frequency domain resource are continuous, then the multiple discrete second frequency domain resources are packaged and integrated into a single cell corresponding to the first frequency domain resource. In this scenario, the network device configures the resource block binding size corresponding to each second frequency domain resource for the terminal device, which is conducive to the terminal device determining the resource group corresponding to each second frequency domain resource based on the resource block binding size corresponding to each second frequency domain resource, so that the terminal device can perform resource block binding, which can reduce the power consumption of the terminal device.

[0024] In an optional implementation, the first frequency domain resource is a bandwidth part (BWP), the second frequency domain resource is a carrier, the resource block is a physical resource block (PRB), the resource block bundling size is a physical resource block (PRB) bundling size, and the resource group is a physical resource block group (PRG). Thus, multiple discrete carriers are packaged and integrated into a single cell corresponding to the BWP.

[0025] In one optional implementation, the resource block bundles corresponding to each second frequency domain resource are of the same size, and the resource group corresponding to each second frequency domain resource includes M resource blocks, where M resource blocks are resource blocks occupied by the second frequency domain resource, and M is a positive integer. Alternatively, it can be understood that the resource block bundles corresponding to each second frequency domain resource are of the same size, and the size of the resource group corresponding to each second frequency domain resource is M.

[0026] It can be seen that when the resource block binding sizes corresponding to each second frequency domain resource are the same, the resource group corresponding to each second frequency domain resource may include M resource blocks occupied by the second frequency domain resource itself.

[0027] Optionally, when the resource block binding sizes corresponding to each second frequency domain resource are the same and are all configured as broadband, the resource group corresponding to each second frequency domain resource includes M resource blocks.

[0028] In another optional implementation, the resource block binding size corresponding to each second frequency domain resource is the same, and the resource block binding size corresponding to each second frequency domain resource is the same. For the nth second frequency domain resource among the multiple second frequency domain resources: the size of the first resource group of the nth second frequency domain resource is P′-N start,n modP′; if (N start,n +N size,n )mod P′≠0, the size of the last resource group of the nth second frequency domain resource is (N start,n +N size,n )mod P′; if (N start,n +N size,n)mod P′=0, the size of the last resource group of the nth second frequency domain resource is P′. start,n is the starting number of the resource block in the nth second frequency domain resource, N size,n is the number of resource blocks included in the nth second frequency domain resource, P′ is the resource block bundling size corresponding to multiple second frequency domain resources, mod is the remainder function, and P′ and n are positive integers.

[0029] It can be seen that when the resource block bundling size corresponding to each second frequency domain resource is the same, for the nth second frequency domain resource among the multiple second frequency domain resources, the sizes of the first resource group and the last resource group corresponding to the nth second frequency domain resource can be determined based on the resource block bundling size corresponding to the multiple second frequency domain resources, the starting number of the resource blocks in the nth second frequency domain resource, and the number of resource blocks included in the nth second frequency domain resource. In addition, the size of the other resource groups corresponding to the nth second frequency domain resource is P′.

[0030] In another optional implementation, P′ is determined based on one of the following: the sum of the bandwidths of the multiple second frequency domain resources, the maximum frequency domain interval of the multiple second frequency domain resources, or the minimum frequency domain interval of the multiple second frequency domain resources.

[0031] In another optional implementation, the resource block bundling size corresponding to each second frequency domain resource is different, and the resource group corresponding to the nth second frequency domain resource includes M resource blocks, where M resource blocks are the resource blocks occupied by the second frequency domain resource, and M and n are positive integers. Alternatively, it can be understood that the resource block bundling size corresponding to each second frequency domain resource is different, and the size of the resource group corresponding to the nth second frequency domain resource is M.

[0032] It can be seen that the resource block binding size corresponding to each second frequency domain resource is different, and the resource group corresponding to the nth second frequency domain resource among multiple second frequency domain resources may include M resource blocks occupied by the nth second frequency domain resource itself.

[0033] Optionally, the resource block binding size corresponding to each second frequency domain resource is different, and when the resource block binding size corresponding to the nth second frequency domain resource among multiple second frequency domain resources is configured as broadband, the resource group corresponding to the nth second frequency domain resource includes M resource blocks.

[0034] In an optional implementation manner, the resource block binding size corresponding to each second frequency domain resource is different. For the nth second frequency domain resource among the multiple second frequency domain resources: the size of the first resource group of the nth second frequency domain resource is P′ n -N start,n modP′ n ; If (N start,n +N size,n )modP′n ≠0, the size of the last resource group of the nth second frequency domain resource is (N start,n +N size,n )modP′ n ; If (N srart,n +N size,n )modP′ n = 0, the size of the last resource group of the nth second frequency domain resource is P′ n Among them, N start,n is the starting number of the resource block in the nth second frequency domain resource, N size,n is the number of resource blocks included in the nth second frequency domain resource, P′ n is the resource block binding size corresponding to the nth second frequency domain resource, mod is the remainder function, P′ n and n are positive integers.

[0035] It can be seen that the resource block binding size corresponding to each second frequency domain resource is different. For the nth second frequency domain resource among multiple second frequency domain resources, the size of the first resource group and the last resource group corresponding to the nth second frequency domain resource can be determined based on the resource block binding size corresponding to the nth second frequency domain resource, the starting number of the resource block in the nth second frequency domain resource, and the number of resource blocks included in the nth second frequency domain resource. In addition, the sizes of other resource groups corresponding to the nth second frequency domain resource are all P′ n .

[0036] In an optional embodiment, P′ n It is determined based on the bandwidth or frequency domain interval of the nth second frequency domain resource.

[0037] In an optional implementation, different resource groups use different precoding matrices. Therefore, when a network device uses different resource groups for data transmission, it can use different precoding matrices.

[0090] The embodiments disclosed herein will present various aspects, embodiments, or features of the present invention centered around a system comprising multiple devices, components, modules, etc. It should be understood that each system may include additional devices, components, modules, etc., and / or may not include all of the devices, components, modules, etc. discussed in conjunction with the accompanying drawings. Furthermore, combinations of these solutions may also be used.

[0091] The following is an introduction to the relevant concepts involved in the embodiments of this application:

[0092] 1. Carrier aggregation (CA).

[0093] Carrier aggregation (CA) is a technology that addresses the limited bandwidth of a single carrier. It aggregates two or more component carriers (CCs) to serve terminal devices, thereby supporting a larger transmission bandwidth. In carrier aggregation, there can be multiple cells providing services for a terminal device. In other words, a terminal device has multiple serving cells, including a primary cell (PCell) and one or more secondary cells (SCells). Figure 2 is a schematic diagram of carrier aggregation. As shown in Figure 2, the cells providing services for the terminal device include PCell (Cell 1) and two SCells (Cell 2 and Cell 3). The center frequencies of Cell 1, Cell 2, and Cell 3 are F1, F2, and F3, respectively.

[0094] The PCell is the cell where a terminal device establishes an initial connection, the cell where a radio resource control (RRC) connection is reestablished, or the designated primary cell during a handover. The PCell is responsible for RRC communication with the terminal device. The component carrier corresponding to the PCell is called the primary component carrier (PCC). For example, the component carrier corresponding to Cell 1 in Figure 2 is the PCC.

[0095] An SCell is added by a terminal device during RRC reconfiguration to provide additional radio resources. There is no RRC communication between the SCell and the terminal device. The component carrier corresponding to the SCell is called a secondary component carrier (SCC). For example, Cell 2 and Cell 3 in Figure 2 correspond to SCC1 and SCC2, respectively.

[0096] 2. Management of carrier aggregation and packaging of multiple discrete carriers.

[0097] Please refer to Figure 3, which is a schematic diagram of carrier aggregation management. As shown in Figure 3, in this carrier aggregation, each service cell corresponds to an independent medium access control (MAC) layer and physical layer (PHY). In addition, to improve the spectrum utilization efficiency of multiple carriers, multiple carriers can be managed uniformly at the L1 / L2 layer to reduce latency and save signaling overhead. Specifically, for unified management at the L1 layer, the downlink control information (DCI) of multiple service cells can be sent uniformly on one cell, thereby saving signaling overhead for other cells; network equipment can also dynamically switch service cells based on the channels and loads on each cell to improve user experience. For unified management at the L2 layer, the SCell can utilize the channel correlation with the PCell to reduce the number of beam scans in activation and achieve rapid activation of the SCell.

[0098] Furthermore, as shown in Figure 3, carrier 1 corresponds to serving cell 1, carrier 2 corresponds to serving cell 2, and carrier 3 corresponds to serving cell 3. Network equipment (such as the remote radio unit (RRU) / AAU in Figure 3) can simultaneously communicate with terminal devices using carriers 1, 2, and 3. As can be seen, in the carrier aggregation shown in Figure 3, different carrier resources belong to different serving cells, and therefore cell configuration for different carrier resources must be performed independently.

[0099] However, for some carriers below (Sub) 3 GHz, the bandwidth of each carrier is small, and the frequency spacing between carriers is also small. For discrete carrier resources with such close carrier spacing, if independent cell-level configuration and management are still performed, there will be a large overhead. Therefore, in the future, it is possible to package and merge multiple discrete carriers into an integrated single cell. Please refer to Figure 4, which is a schematic diagram of a fusion of multiple discrete carriers into a single cell. As shown in Figure 4, carriers 1, 2, and 3 are fused and packaged into fused service cell 1. That is, carriers 1, 2, and 3 correspond to one service cell, so that network equipment can perform unified configuration and management of carriers 1, 2, and 3.

[0100] In future systems (such as 6G systems), multiple discrete frequency domain resources may be packaged and integrated into a single cell. Specifically, multiple discrete frequency domain resources correspond to one serving cell. Multiple discrete frequency domain resources refer to non-contiguous resource blocks between multiple frequency domain resources. This integration of multiple discrete frequency domain resources can reduce the number of serving cells operated simultaneously by operators, improve the stickiness of multiple frequency domain resources, and facilitate re-farming.

[0101] 3. Carrier configuration, physical resource block bundling (PRB bundling) and resource block bundling.

[0102] In carrier aggregation, each carrier can be configured with an independent bandwidth part (BWP). Figure 5 is a schematic diagram of a BWP. The BWP shown in Figure 5 includes BWP 0, BWP 1, and BWP 2. BWP 0 includes N1+1 physical resource blocks (PRBs), BWP 1 includes N2+1 PRBs, and BWP 2 includes N3+1 PRBs. N1, N2, and N3 are all integers. Each BWP includes two parameters, one for the starting number of the PRB in the BWP, and the other for the starting number of the PRB in the BWP. The other is the number of PRBs included in the BWP In addition, in FIG5 , common resource block (CRB) 0 is the reference number of the PRB in each BWP, that is, the PRBs in each BWP are numbered with reference to CRB 0.

[0103] Physical resource block bundling (PRB bundling) refers to a technique in which, when a network device and a terminal device use a physical downlink shared channel (PDSCH) for transmission using a BWP, the terminal device can assume that several consecutive physical resource blocks (PRBs) use the same precoding matrix. These consecutive PRBs are called a physical resource block group (PRG). Therefore, if a terminal device uses PRB bundling, it must determine the PRG corresponding to the BWP.

[0104] Similarly, in future communication systems, for a frequency domain resource, a terminal device divides the frequency domain resource into one or more resource groups consisting of several consecutive resource blocks, and assumes that when a network device uses the frequency domain resources within the resource group for data transmission, it will use the same precoding matrix. This technology can be called resource block bundling. Optionally, this technology can also use other names, such as resource bundling, etc., and the embodiments of this application do not limit its name.

[0105] When multiple discrete carriers are packed and integrated into an integrated single cell, a BWP may include multiple carriers, and the PRBs between different carriers are non-continuous. For example, Figure 6 is a schematic diagram of another BWP. As shown in Figure 6, the BWP includes carrier 0 with a center frequency of f0 and carrier 1 with a center frequency of f1. Carrier 0 includes N1+1 PRBs, and carrier 1 includes N2+1 PRBs. The PRBs in carrier 0 are numbered from 0 to N1, and the PRBs in carrier 1 are numbered from N1+M1 to N1+M1+N2, where N1, N2, and M1 are all integers. It can be seen that the PRBs of carrier 0 are discontinuous with those of carrier 1, and the PRBs included in carrier 0 and carrier 1 are continuous. In addition, the PRBs in Figure 6 Represents the starting number of PRB in carrier 0, Represents the starting number of PRB in carrier 1, Represents the number of PRBs included in carrier 0, Indicates the number of PRBs included in carrier 1.

[0106] Similarly, in future communication systems, when multiple discrete frequency domain resources are packaged and integrated into a single cell as a collection, a first frequency domain resource includes multiple second frequency domain resources, the resource blocks between different second frequency domain resources in the multiple second frequency domain resources are non-continuous, and the resource blocks of each second frequency domain resource are continuous.

[0107] An embodiment of the present application provides a communication method 100. In this method, a network device sends configuration information to a terminal device, where the configuration information is used to configure a resource block bundling size corresponding to each of a plurality of second frequency domain resources of a first frequency domain resource, wherein the resource blocks between different second frequency domain resources in the plurality of second frequency domain resources are discontinuous and the resource blocks of each second frequency domain resource are contiguous; and the terminal device determines a resource group corresponding to each second frequency domain resource based on the resource block bundling size corresponding to each second frequency domain resource.

[0108] It can be seen that the first frequency domain resources include multiple second frequency domain resources. The resource blocks between different second frequency domain resources in the multiple second frequency domain resources are discontinuous, but the resource blocks of each second frequency domain resource are continuous. Then, the multiple discrete second frequency domain resources are packaged and integrated into a single cell corresponding to the first frequency domain resources. In this scenario, the terminal device can determine the resource group corresponding to each second frequency domain resource based on the resource block binding size corresponding to each configured second frequency domain resource. Then, the terminal device can perform resource block binding for each second frequency domain resource, which can reduce the power consumption of the terminal device.

[0109] The present application embodiment proposes a communication method 100. FIG7 is an interaction diagram of the communication method 100. The communication method 100 is described from the perspective of the interaction between the terminal device and the network device. The communication method 100 includes but is not limited to the following steps:

[0110] S101. A network device sends configuration information to a terminal device, where the configuration information is used to configure a resource block bundling size corresponding to each of a plurality of second frequency domain resources of a first frequency domain resource. Correspondingly, the terminal device receives the configuration information from the network device.

[0111] The resource blocks between different second frequency domain resources in the multiple second frequency domain resources are discontinuous, and the resource blocks of each second frequency domain resource are continuous.

[0112] It can be understood that the first frequency domain resources include multiple second frequency domain resources, the resource blocks between different second frequency domain resources in the multiple second frequency domain resources are discontinuous and the resource blocks of each second frequency domain resource are continuous. It can be considered that: multiple discrete second frequency domain resources are packaged and integrated into the cell corresponding to the first frequency domain resources.

[0113] In addition, the resource block bundling size corresponding to the second frequency domain resources can be understood as: the resource block bundling size referenced when dividing the second frequency domain resources into different groups; or can be understood as: the resource block bundling size used when determining the resource group corresponding to the second frequency domain resources. The resource group corresponding to the second frequency domain resources can be understood as: one or more resource groups obtained by dividing the second frequency domain resources based on the resource block bundling size.

[0114] In one optional implementation, the first frequency domain resource is a bandwidth portion (BWP), and the second frequency domain resource is a carrier. As can be seen, the BWP may include multiple carriers, where the PRBs between different carriers are discontinuous, while the PRBs within each carrier are contiguous. Alternatively, it can be understood that multiple carriers are packaged and integrated into the cell corresponding to the BWP.

[0115] It is understandable that when the first frequency domain resource is a BWP and the second frequency domain resource is a carrier, the resource block is a physical resource block PRB, and the resource block bundling size is a PRB bundling size. In this case, the network device configures the PRB bundling size corresponding to each carrier for the terminal device through configuration information, so that the terminal device can determine the PRG corresponding to each carrier based on the PRB corresponding to each carrier, and then the terminal device can perform PRB bundling, which can reduce the power consumption of the terminal device.

[0116] Optionally, the first frequency domain resource and the second frequency domain resource may also be other forms of frequency domain resources, for example, they may be frequency domain resources defined in a future system (such as a 6G system), which is not limited in this embodiment of the present application. Accordingly, the resource block, resource block bundling size, and resource group may be resource blocks, resource block bundling size, and resource groups defined in a future system, respectively, which are not limited in this embodiment of the present application.

[0117] It can be seen that in the scenario where multiple discrete second frequency domain resources are packaged and integrated into the cell corresponding to the first frequency domain resource, the network device configures the resource block binding size corresponding to each second frequency domain resource in the multiple second frequency domain resources for the terminal device, so that the terminal device can determine the resource group corresponding to each second frequency domain resource based on the resource block binding size corresponding to each second frequency domain resource. The terminal device can perform resource block binding, which can reduce the power consumption of the terminal device.

[0118] In one optional implementation, the network device configures the same resource block bundling size for multiple second frequency domain resources of the first frequency domain resource through configuration information, i.e., the resource block bundling sizes corresponding to the multiple second frequency domain resources are the same. Alternatively, it can be understood that the configuration information includes a resource block bundling size, and the resource block bundling size is the resource block bundling size corresponding to the multiple second frequency domain resources of the first frequency domain resource. Configuring the same resource block bundling size for multiple second frequency domain resources by the network device can reduce signaling overhead.

[0119] Optionally, the network device configures resource block bundling sizes corresponding to the multiple second frequency domain resources as wideband. For example, the network device configures PRB bundling sizes corresponding to the multiple carriers of the BWP as wideband.

[0120] Optionally, the network device configures the resource block bundling size corresponding to the multiple second frequency domain resources to P', where P' is a positive integer. For example, Figure 8 is a schematic diagram of a PRB bundling size. As shown in Figure 8, the network device configures the same PRB bundling size for carrier 0 and carrier 1, and the PRB bundling size corresponding to carrier 0 and carrier 1 is P' BWP .

[0121] In an optional implementation, the network device determines the resource block binding size P′ corresponding to the multiple second frequency domain resources based on the sum of the bandwidths of the multiple second frequency domain resources, or the maximum frequency domain interval of the multiple second frequency domain resources, or the minimum frequency domain interval of the multiple second frequency domain resources.

[0122] It is understandable that when the sum of the bandwidths of the multiple second frequency domain resources is within different ranges, the resource block bundling sizes corresponding to the multiple second frequency domain resources take different values. Thus, the network device determines the resource block bundling sizes corresponding to the multiple second frequency domain resources based on the range of the sum of the bandwidths of the multiple second frequency domain resources.

[0123] Alternatively, when the frequency domain intervals of multiple second frequency domain resources are within different ranges, the resource block bundling sizes corresponding to the multiple second frequency domain resources take different values. Thus, the network device determines the resource block bundling sizes corresponding to the multiple second frequency domain resources based on the range to which the maximum frequency domain interval of the multiple second frequency domain resources belongs or the range to which the minimum frequency domain interval belongs. Among them, the maximum frequency domain interval of the multiple second frequency domain resources refers to the maximum frequency domain interval among the frequency domain intervals of the multiple second frequency domain resources; the minimum frequency domain interval of the multiple second frequency domain resources refers to the minimum frequency domain interval among the frequency domain intervals of the multiple second frequency domain resources. For example, BWP#1 includes carrier 1, carrier 2, and carrier 3, and the subcarrier spacings of carrier 1, carrier 2, and carrier 3 are 15KHz, 30KHz, and 60KHz, respectively. Then, the maximum subcarrier spacing of carrier 1, carrier 2, and carrier 3 is 60KHz, and the minimum subcarrier spacing of carrier 1, carrier 2, and carrier 3 is 15KHz.

[0124] Optionally, the correspondence between the sum of the bandwidths of multiple second frequency domain resources and the resource block binding size corresponding to the multiple second frequency domain resources, or the correspondence between the frequency domain intervals of multiple second frequency domain resources and the resource block binding size corresponding to the multiple second frequency domain resources, can be predefined or pre-negotiated between the network device and the terminal device.

[0125] For example, if the BWP includes n carriers, the sum of the bandwidths of the n carriers and the PRB bundling size corresponding to the n carriers have the corresponding relationship shown in Table 1 below. Where n is a positive integer. Then, when the sum of the bandwidths of the n carriers is within the range of 1-12 MHz, the network device determines the PRB bundling size P' corresponding to the n carriers. BWPis 2; when the sum of the bandwidths of the n carriers is in the range of 12-24 MHz, the network device determines that the PRB bundling size corresponding to the n carriers is 4; when the sum of the bandwidths of the n carriers is in the range of 24-36 MHz, the network device determines that the PRB bundling size corresponding to the n carriers is 6.

[0126] Table 1

[0127] Optionally, the network device can configure the corresponding relationship between the sum of the bandwidths of multiple second frequency domain resources and the resource block binding sizes corresponding to the multiple second frequency domain resources for the terminal device through configuration information, and indicate that the resource block binding sizes corresponding to each second frequency domain resource are the same. In this case, the network device does not configure the specific numerical values ​​of the resource block binding sizes corresponding to the multiple second frequency domain resources. This method allows the terminal device to determine the resource block binding sizes corresponding to the multiple second frequency domain resources based on the corresponding relationship between the sum of the bandwidths of the multiple second frequency domain resources and the resource block binding sizes corresponding to the multiple second frequency domain resources, as well as the sum of the bandwidths of the multiple second frequency domain resources, after receiving the configuration information.

[0128] Similarly, the network device can configure the correspondence between the frequency domain intervals of multiple second frequency domain resources and the resource block binding sizes corresponding to the multiple second frequency domain resources for the terminal device through configuration information, and indicate that the resource block binding sizes corresponding to each second frequency domain resource are the same. In this case, the network device does not configure the specific numerical values ​​of the resource block binding sizes corresponding to the multiple second frequency domain resources. This method allows the terminal device to determine the resource block binding sizes corresponding to the multiple second frequency domain resources based on the correspondence between the frequency domain intervals of the multiple second frequency domain resources and the resource block binding sizes corresponding to the multiple second frequency domain resources, as well as the maximum frequency domain interval or the minimum frequency domain interval of the multiple second frequency domain resources after receiving the configuration information.

[0129] In another optional implementation, the network device configures different resource block binding sizes for multiple second frequency domain resources of the first frequency domain resource through configuration information, that is, the resource block binding sizes corresponding to the multiple second frequency domain resources are different. It can also be understood that: the configuration information includes the resource block binding size corresponding to each second frequency domain resource, and the resource block binding size corresponding to each second frequency domain resource is different. For example, Figure 9 is a schematic diagram of another PRB binding size. As shown in Figure 9, the network device configures different PRB binding sizes for carrier 0 and carrier 1, and the PRB binding size corresponding to carrier 0 is P' BWP,0 , the PRB bundling size corresponding to carrier 1 is P′ BWP,1 .

[0130] Optionally, the network device configures the resource block bundling sizes corresponding to the multiple second frequency domain resources to be different, and configures the resource block bundling size corresponding to the nth second frequency domain resource among the multiple second frequency domain resources to be wideband, where n is a positive integer. For example, the network device configures the PRB bundling sizes corresponding to the multiple carriers of the BWP to be different, and configures the PRB bundling size corresponding to the nth carrier among the multiple carriers to be wideband.

[0131] Optionally, the network device configures the resource block binding sizes corresponding to multiple second frequency domain resources to be different, and for the nth second frequency domain resource among the multiple second frequency domain resources: based on the bandwidth or frequency domain interval of the second frequency domain resource, determine the resource block binding size corresponding to the nth second frequency domain resource. It is understandable that when the bandwidth or frequency domain interval of the second frequency domain resource belongs to different ranges, the resource block binding size corresponding to the second frequency domain resource has different values. Thus, the network device determines the resource block binding size corresponding to the nth second frequency domain resource based on the range to which the bandwidth or frequency domain interval of the nth second frequency domain resource belongs. Among them, the correspondence between the bandwidth or frequency domain interval of the second frequency domain resource and the resource block binding size corresponding to the second frequency domain resource can be predefined or pre-negotiated between the network device and the terminal device.

[0132] For example, when the bandwidth of a carrier is in the range of 1-12 MHz, the network device determines the PRB bundling size of the carrier to be 2. For another example, when the bandwidth of a carrier is in the range of 12-24 MHz, the network device determines the PRB bundling size of the carrier to be 4. When the bandwidth of a carrier is in the range of 24-36 MHz, the network device determines the PRB bundling size of the carrier to be 6.

[0133] In summary, when multiple second frequency domain resources are integrated into a single cell corresponding to a first frequency domain resource, the network device configures the resource block bundling size corresponding to each of the multiple second frequency domain resources for the terminal device through configuration information. The resource block bundling size corresponding to each second frequency domain resource may be the same or different. This approach allows the terminal device to determine the resource group corresponding to each second frequency domain resource based on the resource block bundling size corresponding to each second frequency domain resource, thereby enabling the terminal device to perform resource block bundling and reducing the power consumption of the terminal device.

[0134] S102. The terminal device determines the resource group corresponding to each second frequency domain resource based on the resource block bundling size corresponding to each second frequency domain resource.

[0135] It is understandable that when the resource block bundling size corresponding to each second frequency domain resource is the same or different, the implementation method of the terminal device determining the resource group corresponding to each second frequency domain resource is different. The following describes the implementation method of the terminal device determining the resource group corresponding to each second frequency domain resource in combination with the two cases where the resource block bundling size corresponding to each second frequency domain resource is the same or different:

[0136] Case 1: The resource block bundling sizes corresponding to each second frequency domain resource are the same.

[0137] In an optional implementation, when the resource block binding size corresponding to each second frequency domain resource is the same, the terminal device determines that the resource group corresponding to each second frequency domain resource includes M resource blocks, where the M resource blocks are the resource blocks occupied by the second frequency domain resource. Alternatively, it can be understood that when the resource block binding size corresponding to each second frequency domain resource is the same, the terminal device determines that the size of the resource group corresponding to each second frequency domain resource is M.

[0138] Optionally, when the resource block binding size corresponding to each second frequency domain resource is the same and the resource block binding size corresponding to multiple second frequency domain resources is configured as wideband, the terminal device determines that the resource group corresponding to each second frequency domain resource includes M resource blocks, that is, determines that the size of the resource group corresponding to each second frequency domain resource is M.

[0139] That is to say, when the resource block binding size corresponding to each second frequency domain resource is the same, and the resource block binding size corresponding to multiple second frequency domain resources is configured as wideband, the resource group corresponding to each second frequency domain resource is a resource group, and the resource group includes all resource blocks occupied by the second frequency domain resource, or it can be understood that: the size of the resource group is all resource blocks occupied by the second frequency domain resource.

[0140] For example, when the configuration information is used to configure the resource block bundling size corresponding to each carrier in multiple carriers to be wideband, the terminal device determines a PRG corresponding to each carrier, and the PRG includes all PRBs occupied by the carrier.

[0141] In another optional implementation, when the resource block binding size corresponding to each second frequency domain resource is the same and is P′, for the nth second frequency domain resource among the multiple second frequency domain resources: the size of the first resource group of the nth second frequency domain resource is P′-N start,n modP′; if (N start,n +N size,n )mod P′≠0, the size of the last resource group of the nth second frequency domain resource is (N start,n +N size,n )mod P′; if (N start,n +N size,n)mod P′=0, the size of the last resource group of the nth second frequency domain resource is P′.

[0142] Among them, N start,n is the starting number of the resource block in the nth second frequency domain resource, N size,n is the number of resource blocks included in the nth second frequency domain resource, mod is the remainder function, and P′ and n are positive integers.

[0143] In addition, the size of the first resource group of the nth second frequency domain resource is P′-N start,n modP′, which can be understood as: the size of the first resource group of the nth second frequency domain resource is P′-N start,n modP′ continuous resource blocks, or it can be understood as: the first resource group of the nth second frequency domain resource includes P′-N start,n modP′ consecutive resource blocks. Similarly, the size of the last resource group of the nth second frequency domain resource is (N start,n +N size,n )mod P′, which can be understood as: the size of the last resource group of the nth second frequency domain resource is (N start,n +N size,n ) mod P′ continuous resource blocks, or it can be understood as: the last resource group of the nth second frequency domain resource includes (N start,n +N size,n ) mod P′ consecutive resource blocks. The size of the last resource group of the nth second frequency domain resource is P′, which can be understood as: the size of the last resource group of the nth second frequency domain resource is P′ consecutive resource blocks, or it can be understood as: the last resource group of the nth second frequency domain resource includes P′ consecutive resource blocks.

[0144] It can be seen that if the network device configures the resource block binding size corresponding to multiple second frequency domain resources as P′ through configuration information, the terminal device will use the resource block binding size P′ when determining the resource groups corresponding to multiple second frequency domain resources. Specifically, for the nth second frequency domain resource, the terminal device can determine the size of the first resource group and the size of the last resource group in the resource group corresponding to the nth second frequency domain resource based on P′, the starting number of the resource block in the nth second frequency domain resource, and the number of resource blocks included in the nth second frequency domain resource. In addition, the sizes of other resource groups in the resource group corresponding to the nth second frequency domain resource, except for the first resource group and the last resource group, are all P′, or it can be understood that: other resource groups corresponding to the nth second frequency domain resource all include P′ consecutive resource blocks.

[0145] It can also be understood that when the network device configures the resource block binding size corresponding to multiple second frequency domain resources to P′ through configuration information, for the nth second frequency domain resource, the terminal device can divide all resource blocks in the nth second frequency domain resource into several resource groups based on P′, the starting number of the resource block in the nth second frequency domain resource and the number of resource blocks included in the nth second frequency domain resource, and the number of consecutive resource blocks included in the nth second frequency domain resource, and the number of consecutive resource blocks included in each resource group is less than or equal to P′.

[0146] For example, Figure 10 is a schematic diagram of a PRG. As shown in Figure 10, the BWP includes carrier 1 and carrier 2, the PRBs in carrier 1 are numbered 6-10, and the PRBs in carrier 2 are numbered 15-19. The network device configures the PRB binding size of carrier 1 and carrier 2 as 2 through configuration information. For carrier 1, the terminal device determines that the size of the first PRG corresponding to carrier 1 is 2-6mode2=2; (6+5)mode2≠0, then the size of the last PRG corresponding to carrier 1 is (6+5)mode2=1. Furthermore, as shown in Figure 10, the terminal device determines that the PRG corresponding to carrier 1 includes PRG 1, PRG 2 ​​and PRG 3, PRG 1 includes PRB 6 and PRB 7, PRG 2 ​​includes PRB 8 and PRB 9, and PRG 3 includes PRB10. For carrier 2, the terminal device determines that the size of the first PRG corresponding to carrier 2 is 2-15mode2=1; (15+5)mode2=0, and the size of the last PRG corresponding to carrier 2 is 2. Furthermore, as shown in Figure 10, the terminal device determines that the PRGs corresponding to carrier 2 include PRG 4, PRG 5, and PRG 6, PRG 4 includes PRB 15, PRG 5 includes PRB 16 and PRB 17, and PRG 6 includes PRB 18 and PRB 19.

[0147] Optionally, the network device configures the corresponding relationship between the sum of the bandwidths of multiple second frequency domain resources and the resource block binding sizes corresponding to the multiple second frequency domain resources for the terminal device through configuration information, and indicates that the resource block binding sizes corresponding to the multiple second frequency domain resources are the same. The terminal device determines the resource block binding sizes corresponding to the multiple second frequency domain resources based on the corresponding relationship between the sum of the bandwidths of the multiple second frequency domain resources and the resource block binding sizes corresponding to the multiple second frequency domain resources, as well as the sum of the bandwidths of the multiple second frequency domain resources. The terminal device then determines the resource group corresponding to each second frequency domain resource in the multiple second frequency domain resources based on the resource block binding sizes corresponding to the multiple second frequency domain resources.

[0148] Optionally, the network device configures the correspondence between the frequency domain intervals of multiple second frequency domain resources and the resource block binding sizes corresponding to the multiple second frequency domain resources for the terminal device through configuration information, and indicates that the resource block binding sizes corresponding to the multiple second frequency domain resources are the same. The terminal device determines the resource block binding sizes corresponding to the multiple second frequency domain resources based on the correspondence between the frequency domain intervals of the multiple second frequency domain resources and the resource block binding sizes corresponding to the multiple second frequency domain resources, as well as the maximum frequency domain interval or the minimum frequency domain interval of the multiple second frequency domain resources. The terminal device then determines the resource group corresponding to each second frequency domain resource in the multiple second frequency domain resources based on the resource block binding sizes corresponding to the multiple second frequency domain resources.

[0149] Case 2: The resource block bundling sizes corresponding to each second frequency domain resource are different.

[0150] In an optional implementation, when the configuration information includes a resource block binding size corresponding to each second frequency domain resource in a plurality of second frequency domain resources, the terminal device determines that the resource block binding size corresponding to each second frequency domain resource is different.

[0151] In an optional implementation, when the resource block bundling size corresponding to the nth second frequency domain resource among multiple second frequency domain resources is configured as wideband, the terminal device determines that the resource group corresponding to the nth second frequency domain resource includes M resource blocks, and the M resource blocks are the resource blocks occupied by the nth second frequency domain resource. Alternatively, it can be understood that: when the resource block bundling size corresponding to the nth second frequency domain resource among multiple second frequency domain resources is configured as wideband, the terminal device determines that the size of the resource group corresponding to the nth second frequency domain resource is M.

[0152] For example, the configuration information configures the PRB bundling size corresponding to the nth carrier among multiple carriers as wideband, then the terminal device determines a PRG corresponding to the nth carrier, and the PRG includes all PRBs occupied by the nth carrier.

[0153] In an optional implementation, for the nth second frequency domain resource among the plurality of second frequency domain resources: for the nth second frequency domain resource among the plurality of second frequency domain resources: the size of the first resource group of the nth second frequency domain resource is P′ n -N start,n modP′ n ; If (N start,n +N size,n )modP′ n ≠0, the size of the last resource group of the nth second frequency domain resource is (N start,n +N size,n )modP′ n ; If (N srart,n +N size,n)modP′ n = 0, the size of the last resource group of the nth second frequency domain resource is P′ n .

[0154] Among them, N start,n is the starting number of the resource block in the nth second frequency domain resource, N size,n is the number of resource blocks included in the nth second frequency domain resource, P′ n is the resource block binding size corresponding to the nth second frequency domain resource, mod is the remainder function, P′ n and n are positive integers.

[0155] In addition, the size of the first resource group of the nth second frequency domain resource is P′ n -N start,n modP′ n , which can be understood as: the size of the first resource group of the nth second frequency domain resource is P′ n -N start,n modP′ n consecutive resource blocks, or it can be understood as: the first resource group of the nth second frequency domain resource includes P′ n -N start,n modP′ n The size of the last resource group of the nth second frequency domain resource is (N start,n +N size,n )modP′ n , which can be understood as: the size of the last resource group of the nth second frequency domain resource is (N start,n +N size,n )modP′ n consecutive resource blocks, or it can be understood as: the last resource group of the nth second frequency domain resource includes (N start,n +N size,n )modP′ n The size of the last resource group of the nth second frequency domain resource is P′ n , which can be understood as: the size of the last resource group of the nth second frequency domain resource is P′ n continuous resource blocks; or it can be understood as: the last resource group of the nth second frequency domain resource includes P′ n contiguous resource blocks.

[0156] It can be seen that when the network device configures different resource block binding sizes corresponding to multiple second frequency domain resources through configuration information, the terminal device uses the resource block binding size corresponding to each second frequency domain resource in the multiple second frequency domain resources to determine the resource group corresponding to the second frequency domain resource. Specifically, for the nth second frequency domain resource, the terminal device can be based on the resource block binding size P' corresponding to the nth second frequency domain resource. n , the starting number of the resource block in the nth second frequency domain resource and the number of resource blocks included in the nth second frequency domain resource, determine the size of the first resource group and the size of the last resource group in the resource group corresponding to the nth second frequency domain resource. In addition, the sizes of the other resource groups except the first resource group and the last resource group in the resource group corresponding to the nth second frequency domain resource are all P′ n , which can also be understood as: the other resource groups corresponding to the nth second frequency domain resource all include P′ n contiguous resource blocks.

[0157] That is to say, when the network device configures multiple second frequency domain resources corresponding to different resource block binding sizes through configuration information, for the nth second frequency domain resource, the terminal device can be based on the resource block binding size P' corresponding to the nth second frequency domain resource n , the starting number of the resource block in the nth second frequency domain resource and the number of resource blocks included in the nth second frequency domain resource, dividing all resource blocks in the nth second frequency domain resource into a plurality of resource groups, and the number of consecutive resource blocks included in each resource group is less than or equal to P′ n .

[0158] For example, Figure 11 is a schematic diagram of another PRG. As shown in Figure 11, the BWP includes carrier 1 and carrier 2, the PRBs in carrier 1 are numbered 6-10, and the PRBs in carrier 2 are numbered 15-19. The network device configures a PRB binding size of 2 for carrier 1 and a PRB binding size of 3 for carrier 2 through configuration information. For carrier 1, as described above, the terminal device determines that the PRG corresponding to carrier 1 includes PRG 1, PRG 2, and PRG 3, PRG 1 includes PRB 6 and PRB 7, PRG 2 ​​includes PRB 8 and PRB 9, and PRG 3 includes PRB10. For carrier 2, the terminal device determines that the size of the first PRG corresponding to carrier 2 is 3-15mod3=3; (15+5)mod 3≠0, then the size of the last PRG corresponding to carrier 2 is (15+5)mod 3=2. Furthermore, as shown in FIG11 , the terminal device determines that the PRG corresponding to carrier 2 includes PRG 7 and PRG 8 , PRG 7 includes PRB 15 , PRB 16 , and PRB 17 , and PRG 8 includes PRB 18 and PRB 19 .

[0159] It can be seen that when the network device configures the same or a single resource block binding size for multiple second frequency domain resources through configuration information, the terminal device uses the configured resource block binding size to perform resource block binding on each second frequency domain resource, that is, determines the resource group corresponding to each second frequency domain resource. When the network device configures a different resource block binding size for each second frequency domain resource in the multiple second frequency domain resources through configuration information, the terminal device uses the resource block binding size configured for each second frequency domain resource to perform resource block binding on the second frequency domain resource, that is, determines the resource group corresponding to the second frequency domain resource.

[0160] It is understandable that the terminal device determines the resource group corresponding to each second frequency domain resource, which can be understood as: resource block binding for each second frequency domain resource. Therefore, the terminal device believes that when the network device uses frequency domain resources within the same resource group to transmit data, the precoding matrix used is the same. Furthermore, for each resource group, the terminal device determines the decoding matrix corresponding to each resource group to receive the data transmitted by the network device using each resource group. The method in which the terminal device determines the decoding matrix corresponding to each resource group can reduce the power consumption of the terminal device compared to the terminal device determining the decoding matrix corresponding to each resource block in each second frequency domain resource.

[0161] In one optional implementation, the terminal device determines that when the network device uses different resource groups to transmit data, the precoding matrices used are different, and thus the terminal device determines a decoding matrix corresponding to each resource group. Alternatively, the terminal device determines that when the network device uses different resource groups to transmit data, the precoding matrices used are the same, and thus the terminal device determines a single decoding matrix corresponding to multiple resource groups.

[0162] It can be seen that in the embodiment of the present application, the first frequency domain resource includes multiple second frequency domain resources, and the resource blocks between different second frequency domain resources in the multiple second frequency domain resources are discontinuous and the resource blocks of each second frequency domain resource are continuous, so the multiple discrete second frequency domain resources are packaged and integrated into a single cell corresponding to the first frequency domain resource. In this scenario, the network device configures the resource block binding size of each second frequency domain resource for the terminal device, so that the terminal device determines the resource group corresponding to each second frequency domain resource based on the resource block binding size corresponding to each second frequency domain resource, and then performs resource block binding on each second frequency domain resource, which can reduce the power consumption of the terminal device.
