Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a communication method and apparatus. Background Art

[0002] In a communication system, when a network device and a terminal device use a bandwidth part (BWP) for physical downlink shared channel (PDSCH) transmission, the terminal device may assume that a continuous number of physical resource blocks (PRBs) will use the same precoding matrix, where the continuous number of PRBs is referred to as a physical resource block group (PRG), and this technology is referred to as physical resource block bundling (PRB bundling).

[0003] In the future, it is possible to pack and fuse multiple discrete frequency domain resources (such as multiple carriers) into an integrated single cell. In this case, how the terminal device determines a resource group (such as a PRG) remains an issue to be studied. Summary of the Invention

[0004] Embodiments of this application provide a communication method and apparatus, which can enable a terminal device to determine a resource group in a scenario where multiple discrete frequency domain resources are packed and fused into a single cell, and can reduce the power consumption of the terminal device.

[0005] In a first aspect, embodiments of this application provide a communication method, which can be executed by a terminal device. Here, the terminal device may refer to the terminal device itself, or a processor, module, chip, or chip system in the terminal device that implements this method. In this method, the terminal device receives configuration information, where the configuration information is used to configure the resource block bundling size corresponding to each of multiple second frequency domain resources of a first frequency domain resource. The resource blocks between different second frequency domain resources among the multiple second frequency domain resources are discontinuous, and the resource blocks of each second frequency domain resource are continuous; 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.

[0006] It can be seen that in the embodiments of the present application, the first frequency-domain resource includes a plurality of second frequency-domain resources. The resource blocks between different second frequency-domain resources among the plurality of second frequency-domain resources are discontinuous, and the resource blocks of each second frequency-domain resource are continuous. Then, the plurality of discrete second frequency-domain resources are packaged and fused 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. Furthermore, the terminal device can perform resource block binding on each second frequency-domain resource, which can reduce the power consumption of the terminal device.

[0007] In an alternative embodiment, 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 binding size is the physical resource block (PRB) binding size, and the resource group is a physical resource block group (PRG). It can be seen that a plurality of discrete carriers can be packaged and fused into a single cell corresponding to the BWP.

[0008] In an alternative embodiment, the resource block binding 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. The M resource blocks are the resource blocks occupied by this second frequency-domain resource, where M is a positive integer. Or it can be understood that when the resource block binding 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.

[0009] 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 resource group itself of this second frequency-domain resource.

[0010] Optionally, when the resource block binding size corresponding to each second frequency-domain resource is the same and all are configured as wideband, the resource group corresponding to each second frequency-domain resource includes M resource blocks. Or it can be understood that when the resource block binding size corresponding to each second frequency-domain resource is the same and all are configured as wideband, the size of the resource group corresponding to each second frequency-domain resource is M.

[0011] In another alternative embodiment, the resource block binding size corresponding to each second frequency-domain resource is the same. 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 start，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 (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′. Where N start，n is the starting label of the resource blocks 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 binding size corresponding to multiple second frequency-domain resources, mod is the remainder function, and P′ and n are positive integers.

[0012] It can be seen that when the resource block binding sizes corresponding to each second frequency-domain resource are the same, for the nth second frequency-domain resource among multiple second frequency-domain resources, the terminal device can determine the sizes 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 multiple second frequency-domain resources, the starting label 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. Additionally, the sizes of the other resource groups corresponding to the nth second frequency-domain resource are all P′.

[0013] In an optional implementation manner, P′ is determined based on one of the following: the sum of the bandwidths of multiple second frequency-domain resources, the maximum frequency-domain interval of multiple second frequency-domain resources, or the minimum frequency-domain interval of multiple second frequency-domain resources.

[0014] In another optional implementation manner, the resource block binding sizes corresponding to each second frequency-domain resource are different. The resource group corresponding to the nth second frequency-domain resource among multiple second frequency-domain resources includes M resource blocks, and the M resource blocks are the resource blocks occupied by this second frequency-domain resource. M and n are positive integers. Or it can be understood that: the resource block binding sizes corresponding to each second frequency-domain resource are different, and the size of the resource group corresponding to the nth second frequency-domain resource among multiple second frequency-domain resources is M.

[0015] It can be seen that when the resource block binding sizes corresponding to each second frequency-domain resource are 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 it occupies itself.

[0016] Optionally, the resource block binding sizes corresponding to each second frequency-domain resource are 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 the M resource blocks it occupies itself.

[0017] In another optional implementation manner, the resource block binding sizes corresponding to each second frequency-domain resource are different. For the nth second frequency-domain resource among 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 mod P′ n; If (N start，n + N size，n ) mod P' n ≠ 0, the size of the last resource group of the nth second frequency-domain resource is (N start，n + N size，n ) mod P' n ; If (N start，n + N size，n ) mod P' n = 0, the size of the last resource group of the nth second frequency-domain resource is P' n . Wherein, N start，n is the starting label of the resource blocks 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.

[0018] It can be seen that when the resource block binding sizes corresponding to each second frequency-domain resource are different, for the nth second frequency-domain resource among multiple second frequency-domain resources, the terminal device can determine the sizes 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 label 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 sizes of the other resource groups corresponding to the nth second frequency-domain resource are all P' n .

[0019] In an optional implementation, P' n is determined based on the bandwidth or frequency-domain interval of the nth second frequency-domain resource.

[0020] In an optional implementation, the precoding matrices used between different resource groups are different. It can be seen that the terminal device can consider that when the network device uses the frequency-domain resources in different resource groups for data transmission, the precoding matrices used are different.

[0021] In a second aspect, an embodiment of the present application provides a communication method, which can be executed by a network device. Here, the network device can refer to the network device itself, or a processor, module, chip, or chip system in the network device that implements this method. In this method, the network device sends first configuration information, and the configuration information is used to configure the resource block binding size corresponding to each second frequency-domain resource in multiple second frequency-domain resources of the first frequency-domain resource. The resource blocks between different second frequency-domain resources in the second frequency-domain resources are discontinuous and the resource blocks of each second frequency-domain resource are continuous. The resource block binding size corresponding to each second frequency-domain resource is used to determine the resource group corresponding to the second frequency-domain resource.

[0022] It can be seen that in the embodiments of the present application, the first frequency-domain resource includes a plurality of second frequency-domain resources. The resource blocks between different second frequency-domain resources among the plurality of second frequency-domain resources are discontinuous, and the resource blocks of each second frequency-domain resource are continuous. Then, the plurality of discrete second frequency-domain resources are packaged and fused 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 beneficial for the terminal device to 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, enabling the terminal device to perform resource block binding and reducing the power consumption of the terminal device.

[0023] In an alternative embodiment, 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 binding size is the physical resource block (PRB) binding size, and the resource group is a physical resource block group (PRG). It can be seen that a plurality of discrete carriers are packaged and fused into a single cell corresponding to the BWP.

[0024] In an alternative embodiment, the resource block binding 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. The M resource blocks are the resource blocks occupied by this second frequency-domain resource, where M is a positive integer. Or, it can be understood that: the resource block binding size corresponding to each second frequency-domain resource is the same, and the size of the resource group corresponding to each second frequency-domain resource is M.

[0025] It can be seen that when the resource block binding size corresponding to each second frequency-domain resource is the same, the resource group corresponding to each second frequency-domain resource can include the M resource blocks occupied by this second frequency-domain resource itself.

[0026] Optionally, when the resource block binding size corresponding to each second frequency-domain resource is configured to be the same and broadband, the resource group corresponding to each second frequency-domain resource includes M resource blocks.

[0027] In another alternative embodiment, the resource block binding size corresponding to each second frequency-domain resource is the same. 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 start，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 (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′. Where N start，n is the starting label 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 binding size corresponding to multiple second frequency-domain resources, and mod is the remainder function. P′ and n are positive integers.

[0028] It can be seen that when the resource block binding sizes corresponding to each second frequency-domain resource are the same, for the nth second frequency-domain resource among 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 binding size corresponding to multiple second frequency-domain resources, the starting label 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. Additionally, the size of other resource groups corresponding to the nth second frequency-domain resource is P′.

[0029] In another alternative implementation, P′ is determined based on one of the following: the sum of the bandwidths of multiple second frequency-domain resources, the maximum frequency-domain interval of multiple second frequency-domain resources, or the minimum frequency-domain interval of multiple second frequency-domain resources.

[0030] In another alternative implementation, the resource block binding sizes corresponding to each second frequency-domain resource are different. 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 this second frequency-domain resource. M and n are positive integers. Or, it can be understood that: the resource block binding sizes corresponding to each second frequency-domain resource are different, and the size of the resource group corresponding to the nth second frequency-domain resource is M.

[0031] It can be seen that when the resource block binding sizes corresponding to each second frequency-domain resource are different, the resource group corresponding to the nth second frequency-domain resource among multiple second frequency-domain resources can include the M resource blocks occupied by the nth second frequency-domain resource itself.

[0032] Optionally, the resource block binding sizes corresponding to each second frequency-domain resource are 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.

[0033] In an alternative implementation, the resource block binding sizes corresponding to each second frequency-domain resource are different. For the nth second frequency-domain resource among 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 mod P′ n ; if (N start，n +N size，n ) mod P′n ≠0, the size of the last resource group of the nth second frequency-domain resource is (N start，n +N size，n ) mod P′ n ; if (N start，n +N size，n ) mod P′ n = 0, the size of the last resource group of the nth second frequency-domain resource is P′ n . Wherein, N start，n is the starting label of the resource blocks 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, and P′ n and n are positive integers.

[0034] It can be seen that the resource block binding sizes corresponding to each second frequency-domain resource are different. For the nth second frequency-domain resource among multiple second frequency-domain resources, the sizes of the first and last resource groups 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 label 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 sizes of the other resource groups corresponding to the nth second frequency-domain resource are all P′ n .

[0035] In an alternative implementation, P′ n is determined based on the bandwidth or frequency-domain interval of the nth second frequency-domain resource.

[0036] In an alternative implementation, the precoding matrices used between different resource groups are different. It can be seen that when the network device uses different resource groups for data transmission, different precoding matrices can be used.

In addition, combinations of these solutions can also be used.

[0090] The following introduces relevant concepts related to embodiments of the present application:

[0091] 1. Carrier Aggregation (CA).

[0092] CA is a technology to solve the problem of limited bandwidth of a single carrier. It aggregates two or more component carriers (CCs) together to serve a terminal device to support a larger transmission bandwidth. In carrier aggregation, there can be multiple cells serving a terminal device, that is, a terminal device has multiple serving cells, including a primary cell (PCell) and one or more secondary cells (SCells). Figure 2 FIG. [FIGURE NUMBER] is a schematic diagram of a carrier aggregation. As Figure 2 shown, the cells serving the terminal device include a PCell (Cell 1) and two SCells (Cell 2 and Cell 3), and the center frequencies of Cell 1, Cell 2, and Cell 3 are F1, F2, and F3, respectively.

[0093] Among them, the PCell is the cell for the terminal device to establish an initial connection, or the cell for radio resource control (RRC) connection reconstruction, or the primary cell designated during handover. The PCell is responsible for RRC communication with the terminal device. The carrier unit corresponding to the PCell is called the primary component carrier (PCC), for example Figure 2 the carrier unit corresponding to Cell 1 in FIG. [FIGURE NUMBER] is the PCC.

[0094] Please note that the figure numbers in the translation are placeholders and need to be filled in according to the actual figures in the original text.The SCell is added by the terminal device during RRC reconfiguration to provide additional radio resources. There is no RRC communication between the SCell and the terminal device. The carrier unit corresponding to the SCell is called a secondary component carrier (SCC). For example, Figure 2 Cell 2 and Cell 3 in

[0095] correspond to the carrier units SCC1 and SCC2 respectively.

[0096] Please refer to Figure 3 , Figure 3 for a schematic diagram of the management of carrier aggregation. As Figure 3 shown, in this carrier aggregation, each serving cell corresponds to an independent medium access control (MAC) layer and physical layer (PHY). In addition, to improve the spectral utilization efficiency of multiple carriers, multiple carriers can be uniformly managed at the L1 / L2 layer to reduce latency and save signaling overhead. Specifically, for the unified management at the L1 layer, the downlink control information (DCI) of multiple serving cells can be sent on one cell uniformly, thus saving the signaling overhead of other cells; the network device can also dynamically switch serving cells according to the channels and loads on each cell to improve the user experience. For the unified management at the L2 layer, the SCell can utilize the channel correlation with the PCell to reduce the number of beam scans during activation and achieve fast activation of the SCell.

[0097] In addition, as Figure 3 shown, Carrier 1 corresponds to Serving Cell 1, Carrier 2 corresponds to Serving Cell 2, and Carrier 3 corresponds to Serving Cell 3. The network device (such as the remote radio unit (RRU) / AAU in Figure 3 ) can communicate with the terminal device using Carrier 1, Carrier 2, and Carrier 3 simultaneously. It can be seen that Figure 3 in the carrier aggregation shown, different carrier resources belong to different serving cells, so the cell configurations of different carrier resources need to be independently performed.

[0098] However, for some carriers below (Sub) 3 GHz, the bandwidth of each carrier is small, and the frequency interval between carriers is also small. For such discrete carrier resources with a close carrier interval, if independent cell-level configuration management is still carried out, there will be a large overhead. Therefore, in the future, it is possible to pack and fuse multiple discrete carriers into an integrated single cell. Please refer to Figure 4 ,Figure 4 It is a schematic diagram of multiple discrete carriers being fused into a single cell. As Figure 4 shown, Carrier 1, Carrier 2, and Carrier 3 are fused and packaged into Integrated Serving Cell 1, that is, Carrier 1, Carrier 2, and Carrier 3 correspond to one serving cell, so that the network device can uniformly configure and manage Carrier 1, Carrier 2, and Carrier 3.

[0099] Then, in future systems (such as 6G systems), it may be possible to package and fuse multiple discrete frequency-domain resources into an integrated single cell, that is, multiple discrete frequency-domain resources correspond to one serving cell. Among them, multiple discrete frequency-domain resources refer to the fact that the resource blocks between multiple frequency-domain resources are discontinuous. This way of fusing multiple discrete frequency-domain resources can reduce the number of serving cells that the operator operates simultaneously, and can also enhance the stickiness of multiple frequency-domain resources and promote reclamation.

[0100] 3. Configuration of carriers, physical resource block bundling (PRB bundling), and resource block bundling.

[0101] In carrier aggregation, each carrier can be configured with an independent bandwidth part (BWP). Figure 5 It is a schematic diagram of a BWP. Figure 5 The BWP shown 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 is the starting label of the PRBs in the BWP and the other is the number of PRBs included in the BWP where i represents the label of the BWP. In addition, Figure 5 Common Resource Block (CRB) 0 in [] is the reference label for the PRBs in each BWP, that is, the labels of the PRBs in each BWP are labeled with reference to CRB 0.

[0102] Physical resource block bundling (PRB bundling) means that when a network device and a terminal device use a BWP for physical downlink shared channel (PDSCH) transmission, the terminal device can assume that a continuous number of physical resource blocks (PRBs) will use the same precoding matrix. Among them, a continuous number of PRBs is called a physical resource block group (PRG). Therefore, if the terminal device performs PRB bundling, it is necessary to determine the PRG corresponding to the BWP.

[0103] Similarly, in future communication systems, for a frequency-domain resource, when a terminal device divides the frequency-domain resource into one or more resource groups including a continuous number of resource blocks and assumes that the network device will use the same precoding matrix when transmitting data using the frequency-domain resources within the resource group, it can be called resource block bundling. Optionally, this technology can also use other names, such as resource bundling, etc. The naming in the embodiments of this application is not limited.

[0104] When multiple discrete carriers are packed and fused into an integrated single cell, a BWP may include multiple carriers, and the PRBs between different carriers are discontinuous. For example, Figure 6 is a schematic diagram of another BWP. As Figure 6 shown, this 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 labels of the PRBs in carrier 0 are from 0 to N1, and the labels of the PRBs in carrier 1 are 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 and carrier 1 are discontinuous, and the PRBs included in carrier 0 and carrier 1 are continuous respectively. In addition, Figure 6 in represents the starting label of the PRBs in carrier 0, represents the starting label of the PRBs in carrier 1, represents the number of PRBs included in carrier 0. represents the number of PRBs included in carrier 1.

[0105] Similarly, in future communication systems, when multiple discrete frequency-domain resources are packed and fused into a collective single cell, a first frequency-domain resource includes multiple second frequency-domain resources, and the resource blocks between different second frequency-domain resources are discontinuous, and the resource blocks of each second frequency-domain resource are continuous.

[0106] An embodiment of this 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 the resource block binding size corresponding to each of multiple second frequency-domain resources of a first frequency-domain resource. The resource blocks between different second frequency-domain resources among the multiple second frequency-domain resources are discontinuous, and the resource blocks of each second frequency-domain resource are continuous; the terminal device determines a resource group corresponding to each second frequency-domain resource based on the resource block binding size corresponding to each second frequency-domain resource.

[0107] It can be seen that the first frequency-domain resource includes multiple second frequency-domain resources. The resource blocks between different second frequency-domain resources among the multiple second frequency-domain resources are discontinuous, and the resource blocks of each second frequency-domain resource are continuous. Then, multiple discrete second frequency-domain resources are packaged and fused 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 configured for each second frequency-domain resource. Furthermore, the terminal device can perform resource block binding on each second frequency-domain resource, which can reduce the power consumption of the terminal device.

[0108] An embodiment of this application proposes a communication method 100, Figure 7 which is an interaction schematic 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:

[0109] S101. The network device sends configuration information to the terminal device, where the configuration information is used to configure the resource block binding size corresponding to each of multiple second frequency-domain resources of a first frequency-domain resource. Correspondingly, the terminal device receives the configuration information from the network device.

[0110] Among them, the resource blocks between different second frequency-domain resources among the multiple second frequency-domain resources are discontinuous, and the resource blocks of each second frequency-domain resource are continuous.

[0111] It can be understood that the first frequency-domain resource includes multiple second frequency-domain resources. The resource blocks between different second frequency-domain resources among 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 fused into the cell corresponding to the first frequency-domain resource.

[0112] In addition, the resource block binding size corresponding to the second frequency-domain resource can be understood as: the resource block binding size referred to when dividing the second frequency-domain resource into different groups; or it can be understood as: the resource block binding size used when determining the resource group corresponding to the second frequency-domain resource. The resource group corresponding to the second frequency-domain resource can be understood as: one or more resource groups obtained by dividing the second frequency-domain resource based on the resource block binding size.

[0113] In an alternative embodiment, the first frequency-domain resource is a bandwidth part (BWP), and the second frequency-domain resource is a carrier. It can be seen that a BWP may include multiple carriers, and the physical resource blocks (PRBs) between different carriers among the multiple carriers are discontinuous, while the PRBs in each carrier are continuous. Alternatively, it can also be understood that multiple carriers are packed and integrated into the cell corresponding to the BWP.

[0114] 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 binding size is the PRB binding size. In this case, the network device configures the PRB binding size corresponding to each carrier for the terminal device through configuration information, so that the terminal device can determine the physical resource block group (PRG) corresponding to each carrier based on the PRBs corresponding to each carrier, and then the terminal device can perform PRB binding, which can reduce the power consumption of the terminal device.

[0115] 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). The embodiments of the present application do not limit this. Correspondingly, the resource block, the resource block binding size, and the resource group may be the resource block, the resource block binding size, and the resource group defined in the future system respectively. The embodiments of the present application do not limit this.

[0116] It can be seen that in the scenario where multiple discrete second frequency-domain resources are packed and integrated into the cell corresponding to the first frequency-domain resource, the network device configures the resource block binding size corresponding to each of 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, and the terminal device can perform resource block binding, which can reduce the power consumption of the terminal device.

[0117] In an alternative embodiment, the network device configures the same resource block binding size 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 the same. Alternatively, it can be understood that the configuration information includes a resource block binding size, which is the resource block binding size corresponding to multiple second frequency-domain resources of the first frequency-domain resource. The method of the network device configuring the same resource block binding size for multiple second frequency-domain resources can reduce signaling overhead.

[0118] Optionally, the network device configures the resource block binding sizes corresponding to multiple second frequency-domain resources to be wideband. For example, the network device configures the PRB binding sizes corresponding to multiple carriers of the BWP to be wideband.

[0119] Optionally, the network device configures the resource block binding sizes corresponding to multiple second frequency-domain resources to be P′, where P′ is a positive integer. For example,Figure 8 It is a schematic diagram of the PRB binding size. As Figure 8 shown, the network device configures the same PRB binding size for carrier 0 and carrier 1, and the PRB binding size corresponding to carrier 0 and carrier 1 is P'. BWP .

[0120] 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.

[0121] It can be understood that when the sum of the bandwidths of the multiple second frequency domain resources is in different ranges, the resource block binding sizes corresponding to the multiple second frequency domain resources take different values. Thus, the network device determines the resource block binding size corresponding to the multiple second frequency domain resources based on the range where the sum of the bandwidths of the multiple second frequency domain resources is located.

[0122] Alternatively, when the frequency domain intervals of the multiple second frequency domain resources are in different ranges, the resource block binding sizes corresponding to the multiple second frequency domain resources take different values. Thus, the network device determines the resource block binding size corresponding to the multiple second frequency domain resources based on the range to which the maximum frequency domain interval or the minimum frequency domain interval of the multiple second frequency domain resources 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 intervals of carrier 1, carrier 2, and carrier 3 are 15KHz, 30KHz, and 60KHz respectively. Then, the maximum subcarrier interval of carrier 1, carrier 2, and carrier 3 is 60KHz, and the minimum subcarrier interval of carrier 1, carrier 2, and carrier 3 is 15KHz.

[0123] Optionally, the correspondence between the sum of the bandwidths of the 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 the 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.

[0124] For example, BWP includes n carriers, and the sum of the bandwidths of the n carriers and the PRB binding size corresponding to the n carriers have the correspondence shown in Table 1 below. Among them, n is a positive integer. Then, when the sum of the bandwidths of the n carriers is in the range of 1 - 12MHz, the network device determines the PRB binding size P' corresponding to the n carriers. BWPWhen it is 2; when the sum of the bandwidths of n carriers is in the range of 12 - 24 MHz, the network device determines that the PRB binding size corresponding to the n carriers is 4; when the sum of the bandwidths of n carriers is in the range of 24 - 36 MHz, the network device determines that the PRB binding size corresponding to the n carriers is 6.

[0125] Table 1

[0126] Sum of bandwidths of Nn carriers <![CDATA[P′ BWP > 1 to 12 MHz 2 12 to 24 MHz 4 24 to 36 MHz 6

[0127] Optionally, the network device can configure, through configuration information, 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 for the terminal device, and indicate that the resource block binding size corresponding to each second frequency-domain resource is the same. In this case, the network device does not configure the specific value of the resource block binding size corresponding to the multiple second frequency-domain resources. This method enables the terminal device, after receiving the configuration information, to determine the resource block binding size corresponding to the multiple second frequency-domain resources by itself based on the correspondence between the sum of the bandwidths of the multiple second frequency-domain resources and the resource block binding size corresponding to the multiple second frequency-domain resources, and the sum of the bandwidths of the multiple second frequency-domain resources.

[0128] Similarly, the network device can configure, through configuration information, the correspondence between the frequency-domain interval of multiple second frequency-domain resources and the resource block binding size corresponding to the multiple second frequency-domain resources for the terminal device, and indicate that the resource block binding size corresponding to each second frequency-domain resource is the same. In this case, the network device also does not configure the specific value of the resource block binding size corresponding to the multiple second frequency-domain resources. This method enables the terminal device, after receiving the configuration information, to determine the resource block binding size corresponding to the multiple second frequency-domain resources by itself based on the correspondence between the frequency-domain interval of the multiple second frequency-domain resources and the resource block binding size corresponding to the multiple second frequency-domain resources, and the maximum or minimum frequency-domain interval of the multiple second frequency-domain resources.

[0129] In another alternative 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 sizes corresponding to each second frequency-domain resource are different. For example, Figure 9 is a schematic diagram of another PRB binding size. As Figure 9 shown, the network device configures different PRB binding sizes for carrier 0 and carrier 1. The PRB binding size corresponding to carrier 0 is P' BWP，0 , and the PRB binding size corresponding to carrier 1 is P' BWP，1 .

[0130] Optionally, the network device configures the resource block binding sizes corresponding to multiple second frequency-domain resources to be different, and configures the resource block binding 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 binding sizes corresponding to multiple carriers of a BWP to be different, and configures the PRB binding 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. 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 can be understood that when the bandwidth or frequency-domain interval of the second frequency-domain resource belongs to different ranges, the values of the resource block binding sizes corresponding to the second frequency-domain resources are different. 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 that the PRB binding size of the carrier is 2. For another example, when the bandwidth of a carrier is in the range of 12 - 24 MHz, the network device determines that the PRB binding size of the carrier is 4. When the bandwidth of a carrier is in the range of 24 - 36 MHz, the network device determines that the PRB binding size of the carrier is 6.

[0133] In summary, when multiple second frequency-domain resources are integrated into a single cell corresponding to the first frequency-domain resource, the network device configures the resource block binding size corresponding to each second frequency-domain resource among the multiple second frequency-domain resources through configuration information. Among them, the resource block binding sizes corresponding to each second frequency-domain resource are the same or different. This method enables the terminal device to 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, so that the terminal device can perform resource block binding and reduce 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 binding size corresponding to each second frequency-domain resource.

[0135] It is understandable that when the resource block binding sizes corresponding to each second frequency domain resource are the same or different, the implementation manner for the terminal device to determine the resource group corresponding to each second frequency domain resource is different. The following describes the implementation manner for the terminal device to determine the resource group corresponding to each second frequency domain resource in combination with two cases where the resource block binding sizes corresponding to each second frequency domain resource are the same or different:

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

[0137] In an optional implementation manner, when the resource block binding sizes corresponding to each second frequency domain resource are the same, the terminal device determines that the resource group corresponding to each second frequency domain resource includes M resource blocks, and the M resource blocks are the resource blocks occupied by this second frequency domain resource. Or, it can be understood that: when the resource block binding sizes corresponding to each second frequency domain resource are 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 sizes corresponding to each second frequency domain resource are the same and the resource block binding sizes corresponding to multiple second frequency domain resources are 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 sizes corresponding to each second frequency domain resource are the same and the resource block binding sizes corresponding to multiple second frequency domain resources are configured as wideband, the resource group corresponding to each second frequency domain resource is a resource group, and this resource group includes all the resource blocks occupied by this second frequency domain resource, or it can be understood that: the size of this resource group is all the resource blocks occupied by this second frequency domain resource.

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

[0141] In another optional implementation manner, 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 multiple second frequency domain resources: the size of the first resource group of the nth second frequency domain resource is P′ - N start，n mod P′; if (N start，n + N stze，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, and the size of the last resource group of the nth second frequency-domain resource is P′.

[0142] Where N start，n is the starting label 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 mod P′, which can be understood as: the size of the first resource group of the nth second frequency-domain resource is P′ - N start，n mod P′ consecutive resource blocks, or it can be understood as: the first resource group of the nth second frequency-domain resource includes P′ - N start，n mod P′ 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′ 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 ) 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 the configuration information, when the terminal device determines the resource groups corresponding to the multiple second frequency-domain resources, it all uses the resource block binding size P′. Specifically, for the nth second frequency-domain resource among them, 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 label 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 in the resource group corresponding to the nth second frequency-domain resource except the first resource group and the last resource group is P′, or it can be understood as: the 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 be P' through configuration information, for the nth second frequency domain resource among them, the terminal device can divide all the resource blocks in the nth second frequency domain resource into several resource groups based on P', the starting label 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, and the number of consecutive resource blocks included in each resource group is less than or equal to P'.

[0146] Exemplarily, Figure 10 is a schematic diagram of a PRG. As Figure 10 shown, the BWP includes Carrier 1 and Carrier 2. The labels of the PRBs in Carrier 1 are 6 - 10, and the labels of the PRBs in Carrier 2 are 15 - 19. The PRB binding size configured by the network device for Carrier 1 and Carrier 2 through configuration information is both 2. For Carrier 1, the terminal device determines that the size of the first PRG corresponding to Carrier 1 is 2 - 6 mode 2 = 2; (6 + 5) mode 2 ≠ 0, so the size of the last PRG corresponding to Carrier 1 is (6 + 5) mode 2 = 1. Further, as Figure 10 shown, the terminal device determines that the PRGs corresponding to Carrier 1 include PRG1, PRG2, and PRG3. PRG1 includes PRB6 and PRB7. PRG2 includes PRB8 and PRB9, and PRG3 includes PRB10. For Carrier 2, the terminal device determines that the size of the first PRG corresponding to Carrier 2 is 2 - 15 mode 2 = 1; (15 + 5) mode 2 = 0, so the size of the last PRG corresponding to Carrier 2 is 2. Further, as Figure 10 shown, the terminal device determines that the PRGs corresponding to Carrier 2 include PRG4, PRG5, and PRG6. PRG4 includes PRB15, PRG5 includes PRB16 and PRB17, and PRG6 includes PRB18 and PRB19.

[0147] Optionally, the network device configures 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 through configuration information, and when indicating 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 size corresponding to the multiple second frequency domain resources based on the correspondence between the sum of the bandwidths of the multiple second frequency domain resources and the resource block binding size corresponding to the multiple second frequency domain resources, and the sum of the bandwidths of the multiple second frequency domain resources. The terminal device then determines the resource groups corresponding to each second frequency domain resource among the multiple second frequency domain resources based on the resource block binding size 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 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, and the maximum or 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 among 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 binding sizes corresponding to each second frequency-domain resource are different.

[0150] In an optional implementation manner, when the configuration information includes the resource block binding size corresponding to each second frequency-domain resource among the multiple second frequency-domain resources, the terminal device determines that the resource block binding sizes corresponding to each second frequency-domain resource are different.

[0151] In an optional implementation manner, when the resource block binding size corresponding to the nth second frequency-domain resource among the 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. Or, it can be understood that when the resource block binding size corresponding to the nth second frequency-domain resource among the 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, if the configuration information configures the PRB binding size corresponding to the nth carrier among multiple carriers as wideband, the terminal device determines a PRG corresponding to the nth carrier, and the PRG includes all the PRBs occupied by the nth carrier.

[0153] In an optional implementation manner, for the nth second frequency-domain resource among the multiple second frequency-domain resources: 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) mod P' 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 label 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 mod P' 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 mod P' 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 mod P' n consecutive resource blocks. The size of the last resource group of the nth second frequency-domain resource is (N start，n + N size，n ) mod P' 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 ) mod P' 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 ) mod P' n consecutive resource blocks. 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 consecutive resource blocks; or it can be understood as: the last resource group of the nth second frequency-domain resource includes P' n consecutive resource blocks.

[0156] It can be seen that when the network device configures different resource block binding sizes for multiple second frequency domain resources through configuration information, the terminal device uses the resource block binding size corresponding to each second frequency domain resource among 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 determine the sizes of the first resource group and the last resource group in the resource group corresponding to the nth second frequency domain resource based on the resource block binding size P' corresponding to the nth second frequency domain resource n , the starting label 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 the other resource groups in the resource group corresponding to the nth second frequency domain resource except the first resource group and the last resource group 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 consecutive resource blocks.

[0157] That is to say, when the network device configures different resource block binding sizes for multiple second frequency domain resources through configuration information, for the nth second frequency domain resource, the terminal device can divide all the resource blocks in the nth second frequency domain resource into several resource groups based on the resource block binding size P' corresponding to the nth second frequency domain resource n , the starting label 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 each resource group is less than or equal to P' n .

[0158] Exemplarily, Figure 11 is a schematic diagram of another PRG. As Figure 11 shown, the BWP includes carrier 1 and carrier 2. The labels of the PRBs in carrier 1 are 6 - 10, and the labels of the PRBs in carrier 2 are 15 - 19. The network device configures the PRB binding size for carrier 1 as 2 and the PRB binding size for carrier 2 as 3 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 - 15 mod 3 = 3; (15 + 5) mod 3 ≠ 0, so the size of the last PRG corresponding to carrier 2 is (15 + 5) mod 3 = 2. Furthermore, as Figure 11As shown in the figure, the terminal device determines that the PRGs corresponding to Carrier 2 include 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, to determine the resource group corresponding to each second frequency domain resource. When the network device configures different resource block binding sizes for each second frequency domain resource among 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, to determine 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 performing resource block binding on each second frequency domain resource. Thus, when the terminal device believes that the network device uses the 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 by 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 method by which the terminal device determines the decoding matrix corresponding to each resource block in each second frequency domain resource.

[0161] In an alternative implementation, when the terminal device determines that the network device uses different resource groups to transmit data, the precoding matrices used are different, so the terminal device determines the decoding matrices corresponding to each resource group respectively. Optionally, when the terminal device determines that the network device uses different resource groups to transmit data, the precoding matrices used are the same, so the terminal device only needs to determine one decoding matrix corresponding to multiple resource groups.

[0162] It can be seen that in the embodiments of the present application, the first frequency domain resource includes multiple second frequency domain resources. The resource blocks between different second frequency domain resources among 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 packed and fused into a single cell corresponding to the first frequency domain resource. In this scenario, the network device configures the resource block binding size for each second frequency domain resource for the terminal device. Thus, 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.
