Description

Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to a frequency domain resource configuration method, apparatus, terminal, network-side equipment, and readable storage medium. Background Technology

[0002] Currently, in 5G New Radio (NR) systems, network-side equipment can configure multiple frequency domain resources (e.g., bandwidth parts (BWPs)) for a terminal's serving cell. Based on the terminal's communication needs, one of these BWPs can be activated. The terminal then performs uplink transmission or downlink reception on the activated BWP to communicate with the network-side equipment. In this configuration, multiple BWPs for a terminal's serving cell belong to the same carrier. Furthermore, network-side equipment can also configure frequency domain resources from multiple serving cells for the terminal to improve the terminal's data rate through aggregated large bandwidth.

[0003] However, the above technologies have several drawbacks. The network-side devices have poor flexibility in configuring frequency domain resources for terminals, which fails to meet the communication needs of terminals.

[0014] In a tenth aspect, a readable storage medium is provided, on which a program or instructions are stored, which, when executed by a processor, implement the steps of the method described in the first aspect, or implement the steps of the method described in the second aspect.

[0015] Eleventhly, a wireless communication system is provided, comprising: a terminal and a network-side device, wherein the terminal can be used to perform the steps of the method as described in the first aspect, and the network-side device can be used to perform the steps of the method as described in the second aspect.

[0016] In a twelfth aspect, a chip is provided, the chip including a processor and a communication interface coupled to the processor, the processor being configured to run a program or instructions to implement the steps of the method described in the first aspect, or to implement the steps of the method described in the second aspect.

[0018] In this embodiment, since the terminal can receive the first configuration information sent by the network-side device, and the N frequency domain resources indicated by the first configuration information include M frequency domain resources of cells that have not been configured to belong to, the network-side device can directly configure the frequency domain resources of multiple cells into M frequency domain resources without configuring the cells to which these M frequency domain resources belong. Thus, frequency domain resources distributed across multiple carriers in CA and multiple frequency domain resources on a single carrier in the BWP framework can use the same signaling framework, reducing the complexity of the terminal, network-side device, and protocol. And / or, since the terminal can receive the first configuration information sent by the network-side device, and the N frequency domain resources indicated by the first configuration information include P frequency domain resources belonging to the same cell (i.e., the first cell) but located on different carriers, the network-side device can configure frequency domain resources on different carriers into frequency domain resources within a single virtual cell (i.e., the first cell), thereby simplifying baseband complexity and reducing storage / computing resource overhead. Furthermore, the terminal can simultaneously perform uplink transmission or downlink reception on multiple frequency domain resources among the P frequency domain resources. This can also be understood as multiple frequency domain resources among the P frequency domain resources being activated at the same time, rather than being limited to only one frequency domain resource being activated in a cell at the same time, thereby reducing signaling overhead.

[0019] In this embodiment, since the network-side device can send first configuration information to the terminal, and the N frequency domain resources indicated by the first configuration information include M frequency domain resources of cells that are not configured to belong to any given cell, the network-side device can directly configure the frequency domain resources of multiple cells into M frequency domain resources without configuring the cells to which these M frequency domain resources belong. Thus, frequency domain resources distributed across multiple carriers in CA and multiple frequency domain resources on a single carrier in the BWP framework can use the same signaling framework, reducing the complexity of the terminal, network-side device, and protocol. And / or, since the network-side device can send first configuration information to the terminal, and the N frequency domain resources indicated by the first configuration information include P frequency domain resources belonging to the same cell (i.e., the first cell) but located on different carriers, the network-side device can configure frequency domain resources on different carriers into frequency domain resources within a single virtual cell (i.e., the first cell), thereby simplifying baseband complexity and reducing storage / computing resource overhead. In addition, network-side devices can trigger terminals to simultaneously perform uplink transmission or downlink reception on multiple frequency domain resources among the P frequency domain resources through the first configuration information. This can also be understood as multiple frequency domain resources among the P frequency domain resources being activated at the same time, rather than being limited to only one frequency domain resource being activated in a cell at the same time, thereby reducing signaling overhead.

[0035] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0036] The terminology used in the embodiments of this application will be explained below.

[0037] 1. Carrier Aggregation (CA)

[0038] CA (Carrier Aggregation) is a technology that aggregates the frequency domain resources of multiple carriers into a large bandwidth resource, allowing the terminal to simultaneously perform uplink transmission or downlink reception on this aggregated bandwidth, thereby increasing the terminal's data rate.

[0039] Based on the relationship between the aggregated carriers, CA can be divided into the following types:

[0040] 1) In-band continuous CA: The above multiple carriers belong to the same frequency band and are continuous in the frequency domain.

[0041] 2) In-band discontinuous CA: The above multiple carriers belong to the same frequency band, but are discontinuous in the frequency domain.

[0042] 3) Inter-band CA: The above multiple carriers belong to different frequency bands.

[0043] Generally, the serving cell when a terminal accesses the network becomes the primary cell (PCell) after the terminal enters the RRC connected state. Based on the terminal's service requirements and capabilities, network-side equipment can configure a CA (Central Access Control) for the terminal in the RRC connected state, which manifests as the terminal being configured with multiple secondary cells (SCells). Within the CA, there is only one Media Access Control (MAC) entity; multiple serving cells are aggregated at the MAC layer. The activation / deactivation of SCells can be controlled via RRC messages and the MAC control element (CE).

[0044] 2. BWP

[0045] BWP (Bandwidth-based Prefix) is one of the key mechanisms introduced in 5G NR. In this mechanism, terminals only listen for and transmit signals on frequency domain resources within the active BWP, and not on frequency domain resources outside the active BWP. This excludes Radio Resource Management (RRM) measurements, which have their own bandwidth range. BWP parameter configurations include: BWP bandwidth (number of Physical Resource Blocks (PRBs)), frequency domain location, subcarrier spacing, and cyclic prefix.

[0046] The main reasons for introducing BWP include:

[0047] 1) Terminal bandwidth capability is generally less than the system bandwidth of the cell. Furthermore, if the terminal operates on a bandwidth smaller than its own bandwidth capability when data rate requirements are not high, it is beneficial for the terminal to save power. Therefore, the concept of BWP is defined in NR.

[0048] 2) NR supports multiple subcarrier intervals, and the granularity of resource allocation varies for different subcarrier intervals. Introducing the concept of BWP is beneficial for resource allocation indexing within a BWP, which can reduce the scheduling overhead of DCI.

[0049] In NR, a BWP is a cell-level concept. Before entering RRC connected state, the terminal completes initial access using the initial downlink (DL) / uplink (UL) BWP of the serving cell. After entering RRC connected state, the terminal can be configured with up to four dedicated BWPs in that cell, but only one can be active at a time. If the terminal in RRC connected state is configured with a CA, then each SCell can be configured with up to four BWPs, and only one can be active at a time. When a SCell is active, there is exactly one active BWP; when a SCell is deactivated, all BWPs in that SCell are deactivated. Of the maximum four dedicated BWPs configured for a serving cell, some BWPs may be configured as the default BWP, a dormant BWP, or a first active BWP.

[0050] 3. BWP switching:

[0051] While a serving cell is active, the terminal performs a BWP handover based on the following triggering conditions:

[0052] 1) DCI Trigger: When network-side devices schedule data, they can simultaneously indicate BWP switching during scheduling. Specifically, the BWP indicator carried in the DCI indicates which BWP to switch to, and it also carries a carrier indicator field.

[0053] 2) If bwp-InactivityTimer times out, switch to the default BWP configured for this serving cell.

[0054] 3) For a Special Cell (SpCell), when the RRC message reconfigures the first active BWP of the SpCell, the signaling triggers the terminal to switch to the newly configured first active BWP; for a SCell, the network-side device can configure the first active BWP for the SCell, and when the SCell is activated, the first active BWP of the SCell is automatically activated.

[0055] 4) MAC Layer Initiated Random Access: In Time Division Duplex (TDD) systems, DLBWP and ULBWP are configured and switched in pairs, with the same center frequency but different bandwidths (e.g., DLBWP can have a large bandwidth, and ULBWP can have a small bandwidth). In Frequency Division Duplex (FDD) systems, DLBWP and ULBWP can be configured and controlled completely independently. When no random access resources are configured on the active ULBWP, the terminal needs to switch to the initial BWP to perform random access. When the terminal sends a preamble on an active UL BWP, the terminal needs to receive RAR on the paired DLBWP, thus potentially requiring a DLBWP handover.

[0056] 4. Starting Common Resource Block (CRB)

[0057] CRB is a common benchmark, including the starting point CRB 0 and the granularity. The granularity of CRB is a resource block RB, and the size of the RB is determined by the subcarrier spacing SCS of the BWP. The starting point of CRB, also known as PointA, can be obtained in two ways: Method 1) During the initial access process, it is derived from the frequency domain position of the System Information Block (SIB). The terminal obtains (Kssb + offsetToPointA) by receiving System Information Block 1 (SIB 1), where Kssb is obtained through the MIB and the Physical Broadcast Channel, and offsetToPointA is obtained through SIB1. This serves as the common CRB starting point for all terminals accessing from the same SSB. Method 2) It is obtained through the absolute frequency point PointA configured on the network side. Generally, this is suitable for configuring pointA for uplink FDD carriers that do not contain SSBs.

[0058] In carrier aggregation and single carrier, the network first configures the offset of the carrier's starting position from point A (offsetToCarrier in scs-SpecificCarrier), and then configures the offset of the BWP's starting position from the carrier's starting position. The advantage is that it reduces the configuration RIV overhead of the BWP.

[0064] The frequency domain resource configuration method, apparatus, terminal, network-side device, and readable storage medium provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0065] The frequency domain resource configuration method provided in this application can be executed by a frequency domain resource configuration device, a terminal, a functional module or entity within a terminal, a network-side device, or a functional module or entity within a network-side device. This application uses the execution of the frequency domain resource configuration method by a terminal or a network-side device as an example to illustrate the frequency domain resource configuration method provided in this application.

[0066] Figure 2 A flowchart illustrating the frequency domain resource configuration method provided in an embodiment of this application is shown. Figure 2 As shown, the frequency domain resource configuration method provided in this application embodiment may include the following steps 101 and 102.

[0067] Step 101: The terminal receives the first configuration information sent by the network-side device.

[0068] In this embodiment of the application, the first configuration information indicates N frequency domain resources, where N is a positive integer greater than 1.

[0069] In some embodiments of this application, the terminal can receive first configuration information sent by the network-side device while in a Radio Resource Control (RRC) connection state. Of course, the terminal can also receive the first configuration information while in other connection states, and this application does not limit this to these states.

[0070] In some embodiments of this application, the aforementioned frequency domain resources may include at least one of the following: BWP, sub-bandwidth, etc. Of course, the frequency domain resources may also include other resources, which are not limited in the embodiments of this application.

[0071] In some embodiments of this application, the first configuration information can be carried via dedicated signaling (e.g., RRC reconfiguration message or RRC connection recovery message) or broadcast (System Information Block (SIB)). The first configuration information can be sent multiple times or all at once. For example, the network side sends the first configuration information via an RRC reconfiguration message, configuring one frequency domain resource. Then, it sends the first configuration information again via an RRC reconfiguration message, adding another frequency domain resource, thus configuring the terminal with two frequency domain resources. In this case, the terminal obtains two frequency domain resources by receiving the first configuration information twice.

[0072] In one possible implementation of this application, the first configuration information may include configuration information for N frequency domain resources. This configuration information is used to configure the frequency domain resources and may include at least one of the following: the offset of the starting position of the carrier containing the frequency domain resource from point A; the offset of the starting position of the frequency domain resource from the starting position of the carrier containing the frequency domain resource (e.g., given via locationAndBandwidth); the subcarrier spacing; the cyclic prefix; the length of the frequency domain resource in the frequency domain (e.g., given via locationAndBandwidth); the offset of the starting position of the frequency domain resource from point A; and the offset of the starting position of the frequency domain resource from a given frequency domain reference point.

[0073] In another possible implementation of this application, the first configuration information may include configuration information for a portion of the N frequency domain resources. The first configuration information may explicitly or implicitly indicate whether a portion of the frequency domain resources already configured for the terminal are dedicated frequency domain resources for the terminal. Thus, if a portion of the frequency domain resources already configured for the terminal are dedicated frequency domain resources, the terminal can determine a portion of the N frequency domain resources and the portion of frequency domain resources already configured for the terminal as the N frequency domain resources. It can be understood that in this implementation, the N frequency domain resources may include a portion of the frequency domain resources configured by the configuration information in the first configuration information, and another portion of the frequency domain resources already configured for the terminal.

[0074] The frequency domain resources configured in the aforementioned terminal can be understood as the frequency domain resources already configured in the terminal before receiving the first configuration information. This configured frequency domain resource may include initial frequency domain resources, which are used by the terminal for initial access. For example, the network side may indicate that the initial frequency domain resources can be used in the connected state, in which case the network does not need to configure parameters such as the frequency domain position and subcarrier spacing of the initial frequency domain resources. Alternatively, the protocol may stipulate that the terminal can determine whether the acquired initial frequency domain resources can be considered usable in the connected state based on the content of the first configuration information. This method can also be a frequency domain resource indirectly indicated by the first configuration information. For example, if the first configuration information configures X1 frequency domain resources for the terminal, where X1 is the maximum number of configurable frequency domain resources supported by the terminal, then the terminal determines that the acquired initial frequency domain resources cannot be used as frequency domain resources usable in the connected state, and X1 is a positive integer.

[0075] In some embodiments of this application, the N frequency domain resources may include downlink frequency domain resources or uplink frequency domain resources. In one embodiment, the N frequency domain resources may be N downlink frequency domain resources. In another embodiment, the N frequency domain resources may be N uplink frequency domain resources. In yet another embodiment, the N frequency domain resources may be X² downlink frequency domain resources and N-X² uplink frequency domain resources, where X² is a positive integer.

[0076] In this embodiment of the application, the above-mentioned N frequency domain resources include at least one of the following:

[0077] M frequency domain resources, where M is a positive integer greater than 1, and these M frequency domain resources have not been configured to belong to any cell.

[0078] There are P frequency domain resources, which belong to the first cell and are located on different carriers, where P is a positive integer greater than 1.

[0079] In some embodiments of this application, the aforementioned M frequency domain resources may belong to the same carrier or different carriers. M can be a positive integer greater than or equal to 2.

[0080] In some embodiments of this application, the aforementioned M frequency domain resources can be configured or associated by default with the terminal's primary cell PCell or the terminal's currently only active cell.

[0081] In some embodiments of this application, the state of each of the above N frequency domain resources includes an active state or a deactivated state; the initial state of each of the above M frequency domain resources is indicated by the network-side device or agreed upon by the protocol.

[0082] In some examples, the state of each frequency domain resource can also be a dormant state. That is, the state of each frequency domain resource includes an active state, a deactivated state, or a dormant state.

[0083] In some examples, where the initial state of each of the M frequency domain resources is indicated by the network-side device, the network-side device may display the initial state of each frequency domain resource, or the network-side device may indicate the frequency domain resources in the M frequency domain resources whose initial state is active, while the unindicated frequency domain resources are inactive in the initial state.

[0084] In some examples, where the initial state of each of the M frequency domain resources is defined by the protocol, the protocol can define a method for determining the frequency domain resources whose initial state is active, so that the terminal can determine the initial state of each of the M frequency domain resources according to this method.

[0085] In some examples, the terminal can activate / deactivate frequency domain resources according to the initial state of each frequency domain resource.

[0086] Thus, since the embodiments of this application specify the possible states of each frequency domain resource, and the state of each frequency domain resource among the M frequency domain resources can be determined by the network-side device or by the protocol, after the terminal learns of the M frequency domain resources, it can accurately determine the initial state of each frequency domain resource and perform uplink transmission or downlink reception on the frequency domain resources that are in the active state among the N frequency domain resources. This allows the terminal to have a consistent understanding with the network-side device of the frequency domain resources that are in the active state of the terminal, thereby improving the reliability of terminal communication.

[0087] In some embodiments of this application, the M frequency domain resources mentioned above include initial frequency domain resources, which are frequency domain resources used for initial access.

[0088] It is understood that the initial frequency domain resource is the frequency domain resource used by the terminal for initial access, and this initial frequency domain resource can be a frequency domain resource in the frequency domain resources that the terminal has already configured. In this embodiment, it can be directly assumed that the initial frequency domain resource is included among the M frequency domain resources.

[0089] Thus, since the M frequency domain resources include the initial frequency domain resources, which are the frequency domain resources that have been configured in the terminal, the network-side device can omit the configuration information of the initial frequency domain resources in the first configuration information, thereby reducing the resource overhead of the network-side device in sending the first configuration information.

[0090] In some embodiments of this application, when a first condition is met, the M frequency domain resources include an initial frequency domain resource; wherein, the first condition includes at least one of the following: the first configuration information includes first indication information, which is used to indicate that the initial frequency domain resource is a dedicated frequency domain resource of the terminal; the first configuration information is used to configure M-1 frequency domain resources, and the number of the M-1 frequency domain resources is less than or equal to the maximum number of frequency domain resources that the terminal can configure, and the initial frequency domain resource is not included in the M-1 frequency domain resources.

[0091] In some embodiments of this application, the maximum number of frequency domain resources that a terminal can configure includes at least one of the following: the maximum number of frequency domain resources that a terminal can configure as agreed in the protocol, and the maximum number of frequency domain resources that a terminal supports.

[0092] It is understood that, in the embodiments of this application, the first configuration information can explicitly indicate whether the initial frequency domain resource is a dedicated frequency domain resource of the terminal through the first indication information. And / or, the first configuration information can implicitly indicate whether the initial frequency domain resource is a dedicated frequency domain resource of the terminal through the relationship between the number of configuration information of the frequency domain resources included in the first configuration information and the maximum number of frequency domain resources that the terminal can configure.

[0093] Thus, since the terminal can determine that the initial frequency domain resource is included among the M frequency domain resources when the first configuration information includes the first indication information, a consensus can be reached with the network side regarding whether the initial frequency domain resource can be used by the connected terminal, thereby ensuring normal communication. And / or, since the terminal can determine that the initial frequency domain resource is included among the M frequency domain resources when the number of M-1 frequency domain resources is less than or equal to the maximum number of frequency domain resources that the terminal can configure, without requiring additional indication from the network side device, the signaling overhead of the system can be reduced compared to the method where the first configuration information carries the first indication information.

[0094] In this embodiment of the application, P can be a positive integer greater than or equal to 2.

[0095] In some embodiments of this application, the fact that the P frequency domain resources reside on different carriers can be understood as meaning that the P frequency domain resources can belong to different carriers. For example, the P frequency domain resources can belong to P different carriers.

[0096] In some embodiments of this application, the first configuration information mentioned above includes:

[0097] M first identifiers, each first identifier is used by the terminal to uniquely identify a frequency domain resource from the M frequency domain resources.

[0098] In some embodiments of this application, when M frequency domain resources are included among N frequency domain resources, the first configuration information may include M first identifiers.

[0099] In some embodiments of this application, the terminal can uniformly number the M frequency domain resources, with the M first identifiers ID ranging from 0 to M-1. Where the M frequency domain resources include an initial frequency domain resource, the first identifier corresponding to that initial frequency domain resource can be 0.

[0100] Thus, since the first configuration information can include M first identifiers, the terminal can directly determine the corresponding frequency domain resource from the M frequency domain resources based on the first identifier, without having to determine the corresponding frequency domain resource through the cell identifier and the identifier of the frequency domain resource in the cell, as is the case in related technologies. Therefore, the amount of computation required for the terminal to determine the frequency domain resource can be reduced, thereby reducing the complexity of the terminal.

[0101] In some embodiments of this application, the first configuration information may further include:

[0102] N second identifiers, each second identifier is used by the terminal to uniquely identify a frequency domain resource from N frequency domain resources.

[0103] It can be understood that a portion of the N second identifiers can be used by the terminal to uniquely identify a frequency domain resource from M frequency domain resources, and a portion of the N second identifiers can be used by the terminal to uniquely identify a frequency domain resource from P frequency domain resources.

[0104] In some embodiments of this application, the terminal can uniformly number N frequency domain resources, with N first identifiers ID ranging from 0 to N-1. Where the N frequency domain resources include an initial frequency domain resource, the first identifier corresponding to that initial frequency domain resource can be 0.

[0105] Thus, since the first configuration information can include N second identifiers, the terminal can directly determine the corresponding frequency domain resource from the N frequency domain resources based on the second identifier, without having to determine the corresponding frequency domain resource through the cell identifier and resource identifier corresponding to the frequency domain resource as in related technologies. Therefore, the amount of calculation required for the terminal to determine the frequency domain resource can be reduced, thereby reducing the complexity of the terminal.

[0106] In some embodiments of this application, the aforementioned M frequency domain resources may include special frequency domain resources and M-1 ordinary frequency domain resources, or the M frequency domain resources may only include ordinary frequency domain resources. The special frequency domain resources and the M-1 ordinary frequency domain resources differ in function or terminal behavior, allowing the terminal to perform relevant operations (e.g., activation, deactivation, corresponding timer operations, etc.) based on the special frequency domain resources and the M-1 ordinary frequency domain resources. This function may include at least one of uplink transmission and downlink reception, and the behavior may include at least one of activation, deactivation, and corresponding timer operations. For example, a reference signal for wireless link monitoring will always be configured on the special frequency domain resources. Furthermore, when the terminal deactivates the last activated frequency domain resource, the terminal activates the special frequency domain resource.

[0107] The aforementioned special frequency domain resources may also be referred to as any of the following: main frequency domain resources, anchor frequency domain resources, terminal-level default frequency domain resources, etc. Of course, these special frequency domain resources may also be called by other names, and this application embodiment does not limit this.

[0108] In some embodiments of this application, the N frequency domain resources may further include X frequency domain resources of the first cell, where X is a natural number. These X frequency domain resources and P frequency domain resources are divided into at least one frequency domain resource group. The P frequency domain resources may belong to the same frequency domain resource group or different frequency domain resource groups, thereby allowing the terminal to perform relevant operations on the frequency domain resources (e.g., activation, deactivation, corresponding timer operations, etc.) based on at least one frequency domain resource group.

[0109] Step 102: The terminal performs uplink transmission or downlink reception on the active frequency domain resources among the N frequency domain resources according to the first configuration information.

[0110] In some embodiments of this application, the terminal may first determine N frequency domain resources according to the first configuration information, and then activate some of the N frequency domain resources according to the network side device instruction, network side device configuration or protocol agreement, and perform uplink transmission or downlink reception on the frequency domain resources in the activated state.

[0111] In some embodiments of this application, the terminal may only transmit and receive signals (such as data transmission and reception, signaling transmission and reception, and reference signal transmission and reception) within the frequency domain resources that are active in the N frequency domain resources. Outside of these frequency domain resources, the terminal does not need to perform these actions (i.e., data transmission and reception, signaling transmission and reception, and reference signal transmission and reception).

[0112] This application provides a frequency domain resource configuration method. A terminal receives first configuration information indicating N frequency domain resources from a network-side device, where N is a positive integer greater than 1. Based on the first configuration information, the terminal performs uplink transmission or downlink reception on the active frequency domain resources among the N frequency domain resources. The N frequency domain resources include at least one of the following: M frequency domain resources, where M is a positive integer greater than 1, and P frequency domain resources, where P belongs to a first cell and the carriers of the P frequency domain resources are different, where P is a positive integer greater than 1. Since the terminal can receive the first configuration information from the network-side device, and the N frequency domain resources indicated by the first configuration information include M frequency domain resources that are not configured to belong to a cell, the network-side device can directly configure the frequency domain resources of multiple cells as M frequency domain resources without configuring the cells to which these M frequency domain resources belong. Thus, frequency domain resources distributed across multiple carriers in CA and multiple frequency domain resources on a single carrier in the BWP framework can use the same signaling framework, reducing the complexity of terminals, network-side equipment, and protocols. And / or, since the terminal can receive first configuration information sent by the network-side equipment, and the N frequency domain resources indicated by this first configuration information include P frequency domain resources belonging to the same cell (i.e., the first cell) but located on different carriers, the network-side equipment can configure frequency domain resources on different carriers as frequency domain resources within a single virtual cell (i.e., the first cell), thereby simplifying baseband complexity and reducing storage / computing resource overhead. Furthermore, the terminal can simultaneously perform uplink transmission or downlink reception on multiple frequency domain resources among these P frequency domain resources. This can also be understood as multiple frequency domain resources among these P frequency domain resources being activated simultaneously, rather than being limited to only one frequency domain resource being activated in a single cell at any given time, thereby reducing signaling overhead.

[0113] It is understood that in communication systems of related technologies, CA and frequency domain resources have certain similarities in terms of both function and configuration. However, in the embodiments of this application, the M frequency domain resources configured by the network-side device for the terminal may not be configured to belong to any cell, so as to simultaneously meet the requirements of CA and bandwidth adaptation, thereby simplifying the complexity of the protocol and also simplifying the complexity of the terminal and network-side device.

[0114] Furthermore, in related communication systems, there may be underutilized fragmented frequency domain resources (the bandwidth of these fragmented spectrum resources is often very small (e.g., 30 MHz)). However, in the embodiments of this application, the network-side device can aggregate these spectrum resources into a serving cell (e.g., a first cell), which simplifies the complexity of the baseband and reduces storage / computing resource overhead and signaling overhead. This is manifested in that when a serving cell is activated, multiple frequency domain resources of that serving cell are treated as a whole and activated simultaneously.

[0115] Furthermore, in the communication systems of related technologies, within the system bandwidth of a cell, the network-side equipment may be unable to allocate a continuous segment of frequency domain resources to a terminal for various reasons. However, in the embodiments of this application, the network-side equipment can achieve a large bandwidth to meet the service needs of the terminal by configuring multiple non-contiguous active frequency domain resources. Moreover, resource scheduling within the frequency domain resource range will not increase the scheduling overhead of downlink control information (DCI).

[0116] Furthermore, in communication systems of related technologies, some terminals may need to perform multiple services with different SCSs simultaneously, and only one SCS can be supported on each frequency domain resource. However, in the embodiments of this application, the terminal can activate multiple frequency domain resources in a serving cell (e.g., the first cell), thereby enabling the function of performing multiple services with different SCSs simultaneously.

[0117] The following three different examples illustrate the specific schemes for the terminal to perform operations related to frequency domain resources.

[0118] Example 1: N frequency domain resources include M frequency domain resources.

[0119] In some embodiments of this application, the frequency domain resource configuration method provided in this application may further include the following steps 201 and 202, or steps 201 and 203.

[0120] Step 201: The terminal receives the second instruction information sent by the network-side device.

[0121] It should be noted that the execution order of steps 201 and 102 is not limited in this embodiment. In one example, the terminal may execute step 201 first, then step 102; in another example, the terminal may execute step 102 first, then step 201; in yet another example, the terminal may execute step 201 simultaneously with step 102. Figure 3 The example in the text illustrates this by having the terminal execute step 201 first, followed by step 102.

[0122] In this embodiment of the application, the second indication information is used to indicate whether to activate the first frequency domain resource among the M frequency domain resources, or to deactivate the first frequency domain resource.

[0123] In some embodiments of this application, the first frequency domain resource can be any frequency domain resource from M frequency domain resources. The number of the first frequency domain resources can be at least one.

[0124] In some embodiments of this application, when the second indication information is used to indicate the activation of the first frequency domain resource, the second indication information can be an activation command for the frequency domain resource. When the second indication information is used to indicate the deactivation of the first frequency domain resource, the second indication information can be a deactivation command for the frequency domain resource.

[0125] The second indication information may include an identifier for the first frequency domain resource, allowing the terminal to uniquely identify the first frequency domain resource from among the M frequency domain resources based on this identifier. Alternatively, the second indication information may indicate the first frequency domain resource using a bitmap. For example, the second indication information may include M bits, each corresponding to one of the M frequency domain resources. When a bit is 1, it indicates that the corresponding frequency domain resource is activated; when a bit is 0, it indicates that the corresponding frequency domain resource is deactivated. In other words, when the second indication information is used to indicate activation of the first frequency domain resource, the bit corresponding to the first frequency domain resource is 1; when the second indication information is used to indicate deactivation of the first frequency domain resource, the bit corresponding to the first frequency domain resource is 0.

[0126] In some embodiments of this application, the aforementioned second indication information may be carried by at least one of the following: DCI, MACCE, and RRC signaling. Of course, the second indication information may also be carried by other information, and this application does not limit this.

[0127] Step 202: If the second instruction information indicates that the first frequency domain resource should be activated, the terminal activates the first frequency domain resource according to the second instruction information.

[0128] Step 203: If the second instruction information indicates that the first frequency domain resource should be activated, the terminal activates the first frequency domain resource according to the second instruction information.

[0129] Thus, it can be seen that since the terminal can receive the second indication information sent by the network-side device and control the activation / deactivation state of frequency domain resources through the second indication information, it can meet the diverse needs of the terminal for data transmission or energy saving.

[0130] In some embodiments of this application, combined with Figure 2 ,like Figure 3As shown, the frequency domain resource configuration method provided in this application embodiment may further include the following step 204.

[0131] Step 204: If the terminal determines that it wants to activate the second frequency domain resource among the M frequency domain resources, the terminal will activate the third frequency domain resource among the M frequency domain resources.

[0132] It should be noted that the execution order of steps 204 and 102 is not limited in this embodiment. In one example, the terminal may execute step 204 first, then step 102; in another example, the terminal may execute step 102 first, then step 204; in yet another example, the terminal may execute step 204 simultaneously with step 102. Figure 4 The example in the text illustrates this by having the terminal execute step 204 first, followed by step 102.

[0133] In some embodiments of this application, the aforementioned second frequency domain resource can be any frequency domain resource from among M frequency domain resources. The number of such second frequency domain resources can be at least one.

[0134] In this embodiment, the third frequency domain resource is a frequency domain resource in an active state, and the third frequency domain resource and the second frequency domain resource cannot be in an active state at the same time.

[0135] In some embodiments of this application, the term "third frequency domain resource in an active state" can be understood as meaning that the third frequency domain resource is already in an active state before the terminal activates the second frequency domain resource. The number of such third frequency domain resources can be at least one.

[0136] In some embodiments of this application, the terminal may determine to activate the second frequency domain resource upon receiving an instruction from the network-side device to activate the second frequency domain resource; and / or, the terminal may determine to activate the second frequency domain resource when the second frequency domain resource is configured as a special frequency domain resource, after the terminal deactivates the only active frequency domain resource in the terminal. Of course, the terminal may also determine to activate the second frequency domain resource in other circumstances, which are not limited in this embodiment.

[0137] In some embodiments of this application, the terminal may first determine the third frequency domain resource from the frequency domain resources that are in an active state, and then activate the third frequency domain resource from the M frequency domain resources while activating the second frequency domain resource among the M frequency domain resources.

[0138] In some examples, the terminal can use predefined rules to determine the third frequency domain resource. These predefined rules include the relationship between the resource information of the second frequency domain resource and the resource information of the third frequency domain resource, determining the third frequency domain resource from the active frequency domain resources or N frequency domain resources. The resource information may include at least one of the following: carrier, subcarrier spacing, frequency domain range, etc.

[0139] For example, a terminal can determine a third frequency domain resource that belongs to the same carrier as the second frequency domain resource from the active frequency domain resources or N frequency domain resources based on the carrier of the second frequency domain resource.

[0140] For example, the terminal can determine a third frequency domain resource whose frequency domain range overlaps with that of the second frequency domain resource from the active frequency domain resources or N frequency domain resources, based on the frequency domain range of the second frequency domain resource.

[0141] In other examples, the terminal can receive indication information sent by the network-side device. This configuration information includes information about frequency domain resources that cannot be simultaneously active, as well as information about the second frequency domain resource. Based on this information, the terminal can determine the third frequency domain resource from the active frequency domain resources or from N frequency domain resources. For example, if the network-side device configures four frequency domain resources A1, A2, A3, and A4, indicating that A1 and A4 cannot be simultaneously active, and at time 1 the network-side device instructs the terminal to activate A1, and at time 2 the network-side device instructs the terminal to activate A3 and A4, then the terminal activates A3 and A4, while deactivating A1.

[0142] In some embodiments of this application, the terminal may use a predefined method to determine that the third frequency domain resource and the second frequency domain resource cannot be active simultaneously. If the third frequency domain resource is active while the second frequency domain resource is active, then the third frequency domain resource is deactivated. This predefined method may be agreed upon by a protocol, configured by the network-side device, or determined by the terminal itself.

[0143] In some examples, prior to step 204 above, the frequency domain resource configuration method provided in this application embodiment may further include step 205 below, and step 204 above can be specifically implemented through step 204a below.

[0144] Step 205: The terminal receives the third instruction information sent by the network-side device.

[0145] In this embodiment of the application, the aforementioned third indication information is used to indicate that the second frequency domain resource and the third frequency domain resource cannot be active simultaneously. The aforementioned third indication information may be carried by at least one of the following: DCI, MAC CE, or RRC signaling.

[0146] Step 204a: When the terminal activates the second frequency domain resource among the M frequency domain resources, the terminal activates the third frequency domain resource according to the third instruction information.

[0147] In some embodiments of this application, the terminal may first determine the third frequency domain resource from the M frequency domain resources according to the third instruction information, and then activate the third frequency domain resource.

[0148] Thus, since the terminal can receive the third indication information and accurately determine the third frequency domain resource that cannot be active at the same time as the second frequency domain resource through the third indication information, without the need for protocol specification, the complexity of the protocol can be reduced.

[0149] In some other examples, the terminal can receive configuration information sent by the network-side device. This configuration information is used to configure at least one group, each group including at least one of M frequency domain resources. Frequency domain resources in the same group cannot be active at the same time. Thus, the terminal can determine some frequency domain resources from the group where the second frequency domain resource is located, and determine the frequency domain resources that are the same as the active frequency domain resources as the third frequency domain resources.

[0150] In some other examples, the network can be configured to assign an identifier to each frequency domain resource associated with it, which is a frequency domain resource that cannot be active at the same time as the assigned frequency domain resource.

[0151] Thus, since the terminal can activate the third frequency domain resource (which cannot be activated at the same time as the second frequency domain resource) while activating the second frequency domain resource, it can avoid the terminal being unable to perform uplink transmission or downlink reception normally due to the second and third frequency domain resources being activated at the same time in subsequent steps, thereby improving the reliability of terminal communication.

[0152] In some embodiments of this application, the aforementioned M frequency domain resources include a fourth frequency domain resource. In some examples, combined with... Figure 2 ,like Figure 4 As shown, the frequency domain resource configuration method provided in this application embodiment may further include the following steps 206 to 209.

[0153] Step 206: The terminal receives the second configuration information sent by the network-side device.

[0154] It should be noted that the execution order of steps 206 and 101 is not limited in this embodiment. In one example, the terminal may execute step 206 first and then step 101, that is, the terminal may first receive the second configuration information sent by the network-side device and then receive the first configuration information sent by the network-side device; in another example, the terminal may execute step 101 first and then step 206, that is, the terminal may first receive the first configuration information sent by the network-side device and then receive the second configuration information sent by the network-side device; in yet another example, the terminal may execute step 101 while executing step 206, for example, the terminal may simultaneously receive the first and second configuration information sent by the network-side device, or the terminal may receive the first configuration information sent by the network-side device (which includes the second configuration information), or the terminal may receive the second configuration information sent by the network-side device (which includes the first configuration information). Figure 4 This is illustrated by executing step 101 first, followed by step 206.

[0155] In this embodiment of the application, the second configuration information is used to configure a first timer, which is used to periodically trigger the deactivation of the fourth frequency domain resource.

[0156] In some embodiments of this application, the aforementioned second configuration information may be carried by the first configuration information or by other signaling.

[0157] Step 207: When the terminal activates the fourth frequency domain resource according to the second configuration information, the terminal starts the first timer.

[0158] In some embodiments of this application, the second configuration information may include the value of the first timer, which can be understood as the duration of the first timer. Thus, the terminal can first obtain the duration of the first timer according to the second configuration information, and then start the first timer when the terminal activates the fourth frequency domain resource.

[0159] In some embodiments of this application, before step 207 above, the frequency domain resource configuration method provided in the embodiments of this application may further include step 210 below, and step 207 above may be implemented by step 207a, step 207b, or step 207c below.

[0160] Step 210: The terminal receives the third configuration information sent by the network-side device.

[0161] It should be noted that the execution order of steps 210 and 101 is not limited in this embodiment. In one example, the terminal may execute step 210 first and then step 101, that is, the terminal may first receive the third configuration information sent by the network-side device and then receive the first configuration information sent by the network-side device; in another example, the terminal may execute step 101 first and then step 210, that is, the terminal may first receive the first configuration information sent by the network-side device and then receive the third configuration information sent by the network-side device; in yet another example, the terminal may execute step 101 while executing step 210, for example, the terminal may simultaneously receive the first configuration information and the third configuration information sent by the network-side device, or the terminal may receive the first configuration information sent by the network-side device (which includes the third configuration information), or the terminal may receive the third configuration information sent by the network-side device (which includes the first configuration information).

[0162] In this embodiment of the application, the third configuration information is used to configure at least one of the following: the fifth frequency domain resource among the M frequency domain resources associated with the fourth frequency domain resource, and the special frequency domain resource among the M frequency domain resources.

[0163] In some embodiments of this application, the aforementioned fifth frequency domain resource can be any one of the M frequency domain resources other than the fourth frequency domain resource.

[0164] Step 207a: When the terminal activates the fourth frequency domain resource according to the second configuration information, if the third configuration information is used to configure a special frequency domain resource and the fourth frequency domain resource is not a special frequency domain resource, then the terminal starts the first timer.

[0165] In some embodiments of this application, if the third configuration information is used to configure a special frequency domain resource and the fourth frequency domain resource is not a special frequency domain resource, then when the terminal deactivates the fourth frequency domain resource, it activates the special frequency domain resource. That is, deactivating the fourth frequency domain resource will not result in the absence of an active frequency domain resource in the terminal. Therefore, the terminal can start the first timer.

[0166] Step 207b: When the terminal activates the fourth frequency domain resource according to the second configuration information, if the third configuration information is used to configure the fifth frequency domain resource associated with the fourth frequency domain resource, the terminal starts the first timer.

[0167] In some embodiments of this application, if the third configuration information is used to configure the fifth frequency domain resource associated with the fourth frequency domain resource, the terminal can still activate the fifth frequency domain resource when deactivating the fourth frequency domain resource. That is, deactivating the fourth frequency domain resource will not result in the absence of an active frequency domain resource in the terminal. Therefore, the terminal can start the first timer.

[0168] Step 207c: When the terminal activates the fourth frequency domain resource according to the second configuration information, if the third configuration information is used to configure a special frequency domain resource, and the fourth frequency domain resource is a special frequency domain resource, and the fourth frequency domain resource is not the only frequency domain resource that is currently active, then the terminal starts the first timer.

[0169] In some embodiments of this application, if the third configuration information is used to configure special frequency domain resources, and the fourth frequency domain resource is a special frequency domain resource, and the fourth frequency domain resource is not the only frequency domain resource that is currently active in the terminal, then when the terminal deactivates the fourth frequency domain resource, there may still be other frequency domain resources that are active in the terminal. That is, deactivating the fourth frequency domain resource will not result in the absence of active frequency domain resources in the terminal. Therefore, the terminal can start the first timer.

[0170] Thus, since the terminal can receive the third configuration information sent by the network-side device and determine whether deactivating the fourth frequency domain resource might result in the absence of an active frequency domain resource in the terminal, and only starts the first timer if it is determined that deactivating the fourth frequency domain resource will not result in the absence of an active frequency domain resource in the terminal, the occurrence of situations where the terminal deactivates the fourth frequency domain resource due to the first timer expiring, resulting in the absence of an active frequency domain resource in the terminal, can be reduced. This can reduce the occurrence of situations where the terminal cannot communicate with the network-side device, thereby improving the reliability of terminal communication.

[0171] In some embodiments of this application, step 207 can be specifically implemented by step 207d as described below.

[0172] Step 207d: According to the second configuration information, when the terminal activates the fourth frequency domain resource, if the fourth frequency domain resource is not the only frequency domain resource that is currently active, the terminal starts the first timer.

[0173] In some embodiments of this application, if the fourth frequency domain resource is not the only active frequency domain resource currently in the terminal when it is activated, other active frequency domain resources may still exist when the terminal deactivates the fourth frequency domain resource. That is, deactivating the fourth frequency domain resource may not result in the absence of active frequency domain resources in the terminal. Therefore, the terminal can start the first timer. If, during the operation of the first timer, the fourth frequency domain resource becomes the only active frequency domain resource currently in the terminal, the terminal stops the first timer.

[0174] Therefore, before starting the first timer, the terminal can determine whether deactivating the fourth frequency domain resource might result in the absence of an active frequency domain resource in the terminal. The first timer is only started if it is determined that deactivating the fourth frequency domain resource is unlikely to result in the absence of an active frequency domain resource in the terminal. Furthermore, if the fourth frequency domain resource becomes the only active frequency domain resource in the terminal during the first timer's operation, the terminal stops the first timer to prevent the fourth frequency domain resource from being deactivated. Thus, the likelihood of the terminal deactivating the fourth frequency domain resource due to the first timer timing out, resulting in the absence of an active frequency domain resource in the terminal, can be reduced. This reduces the likelihood of the terminal being unable to communicate with network-side devices, thereby improving the reliability of terminal communication.

[0175] Step 208: During the operation of the first timer, if the terminal receives the first downlink control information sent by the network-side device, the terminal restarts the first timer.

[0176] In this embodiment of the application, the first downlink control information is used to schedule the terminal to perform uplink transmission or downlink reception on the fourth frequency domain resources, wherein uplink transmission and downlink reception include initial transmission / new transmission.

[0177] In some embodiments of this application, if the terminal receives the first downlink control information sent by the network-side device during the operation of the first timer, it can be assumed that the network-side device may require the terminal to perform uplink transmission or downlink reception on the fourth frequency domain resources. Therefore, the terminal can restart the first timer to avoid the terminal activating the fourth frequency domain resources when there is a data transmission requirement due to the timer expires, which would result in the inability to perform uplink transmission or downlink reception on the fourth frequency domain resources.

[0178] In some embodiments of this application, the frequency domain resource configuration method provided in this application may further include the following step 211.

[0179] Step 211: If the fourth frequency domain resource is the only frequency domain resource that is currently active in the terminal during the first timer operation, then the terminal stops the first timer.

[0180] In some embodiments of this application, if the fourth frequency domain resource is the only frequency domain resource currently active in the terminal during the first timer operation, the terminal will activate the fourth frequency domain resource when the first timer expires. This may result in no active frequency domain resource in the terminal. Therefore, the terminal can stop the first timer.

[0181] Step 209: When the first timer expires, the terminal deactivates the fourth frequency domain resource.

[0182] In some embodiments of this application, if a fourth frequency domain resource is configured to be associated with a fifth frequency domain resource, the terminal can activate the fifth frequency domain resource when the first timer expires; if a fourth frequency domain resource is not configured to be associated with a fifth frequency domain resource, the terminal only activates the fourth frequency domain resource; if a special frequency domain resource is configured among M frequency domain resources, the terminal can activate the special frequency domain resource when the first timer expires.

[0183] Therefore, since the terminal can start the first timer when activating the fourth frequency domain resource based on the second configuration information, and restart the first timer upon receiving the first downlink control information sent by the network-side device during the first timer's operation, the situation where the terminal is unable to perform uplink transmission or downlink reception on the fourth frequency domain resource when the network-side device requires it to can be reduced. Furthermore, since the terminal can activate the fourth frequency domain resource when the first timer times out (i.e., when the terminal has not performed uplink transmission or downlink reception on the fourth frequency domain resource for a relatively long period), the terminal's power consumption can be reduced. Thus, the terminal's communication performance can be improved while its power consumption is reduced.

[0184] In some embodiments of this application, the frequency domain resource configuration method provided in the embodiments of this application may further include the following steps 210 and 212, or steps 210 and 213, or steps 210 or 214.

[0185] Step 210: The terminal receives the third configuration information sent by the network-side device.

[0186] In this embodiment of the application, the third configuration information is used to configure at least one of the following: the fifth frequency domain resource among the M frequency domain resources associated with the fourth frequency domain resource, and the special frequency domain resource among the M frequency domain resources.

[0187] Step 212: If the third configuration information is used to configure special frequency domain resources, then when the first timer expires, the terminal activates the special frequency domain resources according to the third configuration information.

[0188] In some embodiments of this application, the terminal can determine special frequency domain resources based on third configuration information, and when the first timer expires, the terminal activates the special frequency domain resources based on the third configuration information.

[0189] In this embodiment of the application, since the special frequency domain resources may be frequency domain resources that the network-side device needs the terminal to activate, the terminal can activate the special frequency domain resources according to the third configuration information when the first timer expires.

[0190] Step 213: If the third configuration information is used to configure special frequency domain resources, and the terminal does not currently have any active frequency domain resources when the first timer expires, then when the first timer expires, the terminal activates the special frequency domain resources according to the third configuration information.

[0191] In some embodiments of this application, since the special frequency domain resources may be frequency domain resources that the network-side device needs the terminal to activate, and the terminal does not currently have any active frequency domain resources when the first timer expires, and the fourth frequency domain resource may not have an associated fifth frequency domain resource configured, the terminal can activate the special frequency domain resources according to the third configuration information when the first timer expires, thereby avoiding the situation where there are no active frequency domain resources in the terminal.

[0192] Step 214: If the third configuration information is used to configure the fifth frequency domain resource associated with the fourth frequency domain resource, then when the first timer expires, the terminal activates the fifth frequency domain resource according to the third configuration information.

[0193] Therefore, since the terminal can receive the third configuration information sent by the network-side device and, based on this information, activate the special frequency domain resource or the fifth frequency domain resource when the first timer expires, this reduces the likelihood of the terminal lacking an active frequency domain resource when the first timer expires, thus reducing the possibility of the terminal being unable to communicate with the network-side device. Furthermore, the bandwidth of the special frequency domain resource or the fifth frequency domain resource can be less than that of the fourth frequency domain resource. This means that when the first timer expires, i.e., after a prolonged period without uplink transmission or downlink reception on the larger bandwidth fourth frequency domain resource, the terminal can fall back to the smaller bandwidth special frequency domain resource or the fifth frequency domain resource for uplink transmission or downlink reception. Therefore, this reduces the likelihood of the terminal occupying a larger bandwidth frequency domain resource for an extended period, thereby reducing terminal power consumption.

[0194] The following example will illustrate the complete process of Example 1.

[0195] Taking frequency domain resources as BWP as an example:

[0196] Step 1: The terminal camps on cell 1 and initiates initial access through the cell's initial BWP, entering the connected state.

[0197] Step 2: The terminal is in RRC connected state and receives an RRC reconfiguration message sent by the network-side device, which configures 5 BWPs (e.g., ...). Figure 5The configuration information for BWP 1, BWP 2, BWP 3, BWP 4, and BWP 5 shown includes the frequency domain location and bandwidth, subcarrier spacing, and cyclic prefix configuration for each BWP. The terminal determines that the initial BWP can be used as a dedicated BWP (e.g., as indicated by the RRC reconfiguration message, or when 5 is less than the maximum number of BWPs that the terminal can configure), and the ID of the initial BWP is 0. Wherein, as... Figure 5 As shown, BWP 0 and BWP 1 include SSB 1, BWP 0, BWP 1 and BWP 2 are located on carrier 1, BWP 3, BWP 4 and BWP 5 include SSB 2, and BWP 3, BWP 4 and BWP 5 are located on carrier 2.

[0198] Step 3: The terminal sets the initial state of each BWP. Assuming that the RRC reconfiguration message in Step 2 indicates that BWP1 and BWP4 are in the active state, the terminal sets the initial state of BWP1 and BWP4 to the active state, and sets the states of the remaining BWP0, BWP2, BWP3 and BWP5 to the default deactivated state.

[0199] Step 4: When the terminal activates BWP 1 and BWP 4, the terminal starts the first timer corresponding to each of BWP 1 and BWP 4. For each activated BWP, if there is data scheduled for new transmission on that BWP (e.g., receiving the first downlink control information sent by the network side device), the first timer is restarted. When the first timer expires, the terminal deactivates that BWP.

[0200] In one example, such as Figure 5 As shown, according to the RRC configuration message, the default BWP associated with BWP 1 is BWP 2, and the default BWP associated with BWP 4 is BWP 3. When the first timer corresponding to BWP 4 expires, the terminal deactivates BWP 4 and activates BWP 3. When the first timer corresponding to BWP 1 expires, the terminal deactivates BWP 1 and activates BWP 2.

[0201] In another example, such as Figure 6 As shown, according to the RRC configuration message, the default BWP associated with BWP 1 and BWP 4 is BWP 2. When the timer of BWP 4 expires first, the terminal deactivates BWP 4 and activates BWP 2. When the timer of BWP 1 expires, the terminal deactivates BWP 1. If BWP 2 is still active, the terminal does not need to reactivate BWP 2.

[0202] In another example, such as Figure 7As shown, according to the RRC configuration message, BWP1 is associated with BWP2 as the default BWP, and BWP4 is not associated with a default BWP. When the timer of BWP4 expires first, the terminal deactivates BWP4. When the timer of BWP1 expires, the terminal deactivates BWP1 and activates BWP2.

[0203] Step 5: The terminal operates on two default BWPs, such as BWP 2 and BWP 3. According to the RRC configuration message, if BWP2 is a special BWP (e.g., the primary BWP) and BWP 3 is a secondary BWP, the terminal starts the first timer for each BWP when BWP 2 and BWP 3 are activated. When the first timer expires, the corresponding BWP is deactivated. If only one BWP is active, and that BWP is BWP 2, the terminal stops the first timer. If all BWPs are deactivated, the terminal activates the primary BWP, i.e., activates BWP 2.

[0204] Example 2: N frequency domain resources include P frequency domain resources.

[0205] In some embodiments of this application, the aforementioned N frequency domain resources further include X frequency domain resources of the first cell, which differ from the P frequency domain resources, where X is a natural number. In some examples, combined with... Figure 2 ,like Figure 8 As shown, the frequency domain resource configuration method provided in this application embodiment may further include the following steps 215 and 216.

[0206] Step 215: The terminal receives the fourth configuration information sent by the network-side device.

[0207] It should be noted that the execution order of steps 215 and 101 is not limited in this embodiment. In one example, the terminal may execute step 215 first and then step 101, that is, the terminal may first receive the fourth configuration information sent by the network-side device and then receive the first configuration information sent by the network-side device; in another example, the terminal may execute step 101 first and then step 215, that is, the terminal may first receive the first configuration information sent by the network-side device and then receive the fourth configuration information sent by the network-side device; in yet another example, the terminal may execute step 101 simultaneously with step 215, for example, the terminal may simultaneously receive the first configuration information and the fourth configuration information sent by the network-side device, or the terminal may receive the first configuration information sent by the network-side device (which includes the fourth configuration information), or the terminal may receive the fourth configuration information sent by the network-side device (which includes the first configuration information). Figure 8The example shown is that the terminal executes step 101 first, and then step 215.

[0208] In some embodiments of this application, the first cell described above can be a virtual cell. The X frequency domain resources and P frequency domain resources can be configured by network-side devices, for example, by including configuration information for the X and P frequency domain resources in the first configuration information, or by being determined by the terminal according to predefined rules.

[0209] It is understood that in related technologies, the frequency domain resources of a cell can belong to the same carrier, that is, the frequency domain resources of a cell are located on the same carrier. However, in the embodiments of this application, the first cell is not the same as the cell in related technologies. The first cell can be a virtual cell, and the frequency domain resources of the first cell can include frequency domain resources belonging to different carriers in the system (i.e., P frequency domain resources).

[0210] In this embodiment of the application, the number of X frequency domain resources X is a positive integer, that is, the number of X frequency domain resources can be 0. At this time, X frequency domain resources and P frequency domain resources are P frequency domain resources.

[0211] In some embodiments of this application, where each of the X frequency domain resources and P frequency domain resources contains a different synchronization signal block (SSB), the configuration requirements of the SSB of the first cell are configured based on each of the X frequency domain resources and P frequency domain resources. Alternatively, the serving measurement object (MO) of the first cell may need to be configured in multiple ways.

[0212] In this embodiment of the application, the fourth configuration information is used to indicate Y frequency domain resource groups, each frequency domain resource group including at least one frequency domain resource among multiple frequency domain resources, the multiple frequency domain resources including X frequency domain resources and P frequency domain resources, where Y is a positive integer.

[0213] In some embodiments of this application, the terminal can divide X frequency domain resources and P frequency domain resources into Y frequency domain resource groups according to the Y frequency domain resource groups indicated by the fourth configuration information.

[0214] In some embodiments of this application, the aforementioned Y frequency domain resource groups satisfy at least one of the following:

[0215] Determined by the capabilities of the terminal;

[0216] Determined by the service type of the terminal;

[0217] It is determined by the terminal type.

[0218] In some embodiments of this application, the aforementioned Y frequency domain resource groups can also be determined by the bandwidth supported by the terminal.

[0219] Furthermore, in order to support the above-mentioned grouping method, the terminal also needs to report its capabilities, supported bandwidth, terminal type, and other information to the network-side equipment.

[0220] In some embodiments of this application, the terminal's capabilities may include any of the following: a reduced capability (RedCap) terminal, or a non-RedCap terminal. Of course, the terminal's capabilities may also include other capabilities, which are not limited to the specific capabilities described in this application.

[0221] In some embodiments of this application, the aforementioned service type may include any of the following: Enhanced Mobile Broadband (eMBB), Massive Machine Type Communication (mMTC), and Ultra-Reliable and Low-Latency Communications (URLLC). Of course, the service type may also include other types, which are not limited to those described in this application.

[0222] Thus, since the Y frequency domain resource groups can be determined by the terminal's capabilities and / or by the terminal's service type and / or by the terminal's terminal type, the terminal can directly activate all frequency domain resources in a certain frequency domain resource group according to the network-side device configuration or instructions, without having to determine and activate them one by one from the X and P frequency domain resources. This reduces the complexity of the terminal activating frequency domain resources, thereby reducing the complexity of the terminal.

[0223] In some embodiments of this application, considering that there is always a need in the network to activate only one or a few frequency domain resources in a frequency domain resource group, the network side can also instruct the terminal to activate one of X frequency domain resources or P frequency domain resources. For example, this can be indicated by the identifier of each frequency domain resource, and the desired state can be indicated by the activation / deactivation state field. Alternatively, the network side can indicate a frequency domain resource by using the identifier of the frequency domain resource group and the identifier of each frequency domain resource in the frequency domain resource group, and the desired state can be indicated by the activation / deactivation state field.

[0224] Step 216: The terminal activates the frequency domain resources in the Y frequency domain resource groups according to the fourth configuration information.

[0225] In some embodiments of this application, the terminal can divide the above-mentioned multiple frequency domain resources (i.e., X frequency domain resources and P frequency domain resources) into Y frequency domain resource groups according to the fourth configuration information, and activate the frequency domain resources in the Y frequency domain resource groups according to the instructions of the network side device.

[0226] The terminal can activate all frequency domain resources in one of the Y frequency domain resource groups, or activate all frequency domain resources in each of at least two frequency domain resource groups, according to instructions from the network-side device.

[0227] Thus, since the terminal can receive the fourth configuration information sent by the network-side device and activate the frequency domain resources in the Y frequency domain resource groups based on the fourth configuration information, that is, activate and deactivate frequency domain resources according to the granularity of the frequency domain resource groups, the network-side device does not need to indicate the activated or deactivated frequency domain resources one by one, which helps to reduce signaling overhead.

[0228] In some embodiments of this application, the terminal can also divide X frequency domain resources and P frequency domain resources into Y frequency domain resource groups according to a predefined grouping method.

[0229] For example, a terminal can group the frequency domain resources with bandwidth less than the bandwidth threshold from among X frequency domain resources and P frequency domain resources into one frequency domain resource group, and group the frequency domain resources with bandwidth greater than or equal to the bandwidth threshold from among X frequency domain resources and P frequency domain resources into another frequency domain resource group.

[0230] In some embodiments of this application, step 216 can be specifically implemented by step 216a as described below.

[0231] Step 216a: When the first cell is activated, the terminal activates all frequency domain resources in the first frequency domain resource group among the Y frequency domain resource groups.

[0232] In some embodiments of this application, the first frequency domain resource group may be the first activated frequency domain resource group among Y frequency domain resource groups, or the frequency domain resource group indicated by the network-side device, or the frequency domain resource group determined by the terminal, or the frequency domain resource group agreed upon by the protocol.

[0233] Thus, when the first cell is activated, the terminal can directly activate all frequency domain resources in the first frequency domain resource group without additional instructions from the network side equipment. Therefore, the signaling interaction between the terminal and the network side equipment can be reduced, thereby reducing the signaling overhead of the system.

[0234] In some embodiments of this application, the terminal may also activate a portion of the frequency domain resources in the first frequency domain resource group. These portion of frequency domain resources may be indicated by the network-side device or agreed upon by a protocol.

[0235] In some embodiments of this application, before step 216a above, the frequency domain resource configuration method provided in the embodiments of this application may further include step 217 below, and step 216a above can be specifically implemented by step 216a1 below.

[0236] Step 217: The terminal receives the fourth instruction information sent by the network-side device.

[0237] In this embodiment of the application, the aforementioned fourth indication information is used to indicate the first frequency domain resource group. The aforementioned fourth indication information may be carried by at least one of the following: DCI, MAC CE, and RRC signaling.

[0238] Step 216a1: When the first cell is activated, the terminal activates all frequency domain resources in the first frequency domain resource group according to the fourth configuration information and the fourth instruction information.

[0239] Thus, when the first cell is activated, the terminal immediately activates all frequency domain resources of the first frequency domain resource group of the first cell, thereby meeting the data transmission requirements.

[0240] In some embodiments of this application, before step 216 above, the frequency domain resource configuration method provided in the embodiments of this application may further include step 218 below, and step 216 above may be implemented by step 216b or step 216c below.

[0241] Step 218: The terminal receives the fifth instruction information sent by the network-side device.

[0242] In this embodiment of the application, the fifth instruction information is used to instruct the activation of all frequency domain resources in the second frequency domain resource group of the Y frequency domain resource groups, or to deactivate all frequency domain resources in the second frequency domain resource group of the Y frequency domain resource groups.

[0243] In some embodiments of this application, the aforementioned fifth indication information may be carried by at least one of the following: DCI, MACCE, or RRC signaling.

[0244] In some embodiments of this application, the aforementioned second frequency domain resource group can be any one of the Y frequency domain resource groups.

[0245] Step 216b: When the fifth instruction information indicates that all frequency domain resources in the second frequency domain resource group should be activated, the terminal activates all frequency domain resources in the second frequency domain resource group according to the fourth configuration information and the fifth instruction information.

[0246] In some embodiments of this application, the terminal may first determine Y frequency domain resource groups according to the fourth configuration information, and then determine the second frequency domain resource group from the Y frequency domain resource groups according to the fifth indication information. For example, the fifth indication information may include the identifier of the second frequency domain resource group, so that the terminal can determine the second frequency domain resource group according to the identifier of the second frequency domain resource group and activate all frequency domain resources in the second frequency domain resource group.

[0247] Thus, it can be seen that since the terminal can receive the fifth instruction information sent by the network-side device and activate all frequency domain resources in the second frequency domain resource group through the fifth instruction information, the control signaling overhead of the network side can be reduced.

[0248] Step 216c: When the fifth instruction information indicates to activate all frequency domain resources in the second frequency domain resource group, the terminal activates all frequency domain resources in the second frequency domain resource group according to the fourth configuration information and the fifth instruction information.

[0249] In some embodiments of this application, the terminal may first determine Y frequency domain resource groups according to the fourth configuration information, and then determine the second frequency domain resource group from the Y frequency domain resource groups according to the fifth instruction information, and deactivate all frequency domain resources in the second frequency domain resource group.

[0250] Thus, it can be seen that since the terminal can receive the fifth instruction information sent by the network-side device and activate all frequency domain resources in the second frequency domain resource group through the fifth instruction information, the control signaling overhead of the network side can be reduced.

[0251] In some embodiments of this application, considering that there is always a need in the network to activate only one or a few frequency domain resources in a frequency domain resource group, the network side can also instruct the terminal to activate one of X frequency domain resources or P frequency domain resources. For example, this can be indicated by the identifier of each frequency domain resource, and the desired state can be indicated by the activation / deactivation state field. Alternatively, the network side can indicate a frequency domain resource by using the identifier of the frequency domain resource group and the identifier of each frequency domain resource in the frequency domain resource group, and the desired state can be indicated by the activation / deactivation state field.

[0252] In some embodiments of this application, the aforementioned Y frequency domain resource groups include a third frequency domain resource group. In some examples, combined with Figure 2 ,like Figure 9 As shown, the frequency domain resource configuration method provided in this application embodiment may further include the following steps 219 to 222.

[0253] Step 219: The terminal receives the fifth configuration information sent by the network-side device.

[0254] It should be noted that the execution order of steps 220 and 101 is not limited in this embodiment. In one example, the terminal may execute step 220 first and then step 101, that is, the terminal may first receive the fifth configuration information sent by the network-side device and then receive the first configuration information sent by the network-side device; in another example, the terminal may execute step 101 first and then step 220, that is, the terminal may first receive the first configuration information sent by the network-side device and then receive the fifth configuration information sent by the network-side device; in yet another example, the terminal may execute step 101 while executing step 220, for example, the terminal may simultaneously receive the first configuration information and the fifth configuration information sent by the network-side device, or the terminal may receive the first configuration information sent by the network-side device (which includes the fifth configuration information), or the terminal may receive the fifth configuration information sent by the network-side device (which includes the first configuration information). Figure 9 The example in the text illustrates the process of the terminal executing step 101 first, followed by step 219.

[0255] In this embodiment of the application, the fifth configuration information is used to configure a second timer, which is used to periodically trigger the deactivation of all frequency domain resources in the third frequency domain resource group.

[0256] Step 220: According to the fifth configuration information, when the terminal activates all frequency domain resources in the third frequency domain resource group, the second timer is started.

[0257] It should be noted that the description of the terminal starting the second timer can be found in the specific description of the terminal starting the first timer in the above embodiments, and will not be repeated here in the embodiments of this application.

[0258] Step 221: During the operation of the second timer, if the terminal receives the second downlink control information sent by the network-side device, the terminal restarts the second timer.

[0259] In this embodiment, the aforementioned second downlink control information is used to schedule the terminal to perform uplink transmission or downlink reception on at least a portion of the frequency domain resources in the third frequency domain resource group. Uplink transmission and downlink reception include initial transmission / new transmission.

[0260] Step 222: When the second timer expires, the terminal deactivates all frequency domain resources in the third frequency domain resource group.

[0261] Therefore, since the terminal can start the second timer when activating all frequency domain resources in the third frequency domain resource group according to the fifth configuration information, and restart the second timer when it receives the second downlink control information sent by the network-side device during the second timer's operation, the situation where the terminal is unable to perform uplink transmission or downlink reception on at least some frequency domain resources in the third frequency domain resource group when the network-side device requires the terminal to perform uplink transmission or downlink reception on at least some frequency domain resources in the third frequency domain resource group can be reduced. Furthermore, since the terminal can activate all frequency domain resources in the third frequency domain resource group when the second timer times out, i.e., when the terminal has not performed uplink transmission or downlink reception on any frequency domain resource in the third frequency domain resource group for a relatively long period, the terminal's power consumption can be reduced. Thus, the terminal's communication performance can be improved while its power consumption is reduced.

[0262] In some embodiments of this application, the terminal may also receive seventh configuration information sent by a network-side device. This seventh configuration information is used to configure at least one third timer. Each third timer is used to periodically trigger the deactivation of a frequency domain resource in a frequency domain resource group. Thus, the terminal can start the third timer corresponding to a frequency domain resource when activating a frequency domain resource according to the seventh configuration information. During the operation of the third timer corresponding to the frequency domain resource, if a third downlink control information is received from the network-side device, the third timer corresponding to the frequency domain resource is restarted. The third downlink control information is used to schedule the terminal to perform uplink transmission or downlink reception on the frequency domain resource. And when the third timer corresponding to the frequency domain resource times out, the frequency domain resource is deactivated.

[0263] In some embodiments of this application, the frequency domain resource configuration method provided in this application may further include the following steps 223 and 224.

[0264] Step 223: The terminal receives the sixth configuration information sent by the network-side device.

[0265] In this embodiment of the application, the sixth configuration information is used to configure the default frequency domain resource group among the Y frequency domain resource groups.

[0266] Step 224: According to the sixth configuration information, when the second timer expires, the terminal activates all frequency domain resources in the default frequency domain resource group.

[0267] Thus, since the terminal can receive the sixth configuration information sent by the network-side device and configure the default frequency domain resource group among the Y frequency domain resource groups through the sixth configuration information, when the second timer expires, that is, when the terminal activates all frequency domain resources in the third frequency domain resource group, the terminal can activate all frequency domain resources in the default frequency domain resource group. Therefore, when the bandwidth of the default frequency domain resource group is small, for example, less than the bandwidth of the third frequency domain resource group, the terminal power consumption can be saved.

[0268] In some embodiments of this application, the terminal may also, according to the sixth configuration information, not activate all frequency domain resources in the default frequency domain resource group when the second timer times out.

[0269] In some embodiments of this application, the terminal, based on the sixth configuration information, activates only all frequency domain resources in the third frequency domain resource group when the second timer expires, but does not activate all frequency domain resources in the default frequency domain resource group; or, whether the terminal activates all frequency domain resources in the default frequency domain resource group can be determined by whether the network-side device has configured a default frequency domain resource group for the third frequency domain resource group, or whether a default frequency domain resource group has been configured.

[0270] In some embodiments of this application, the terminal may also activate the default frequency domain resources when the second timer times out, based on the sixth configuration information.

[0271] If the default frequency domain resource group is not configured, but the default frequency domain resource is configured, the terminal can activate the default frequency domain resource when the second timer expires.

[0272] In some embodiments of this application, when the default frequency domain resource group is activated, a third timer corresponding to each frequency domain resource in the default frequency domain resource group can be started. After the third timer corresponding to a certain frequency domain resource in the default frequency domain resource group times out, the terminal deactivates the frequency domain resource. When there is only one frequency domain resource in the default frequency domain resource group that is in an active state, the terminal stops the third timer corresponding to the frequency domain resource.

[0273] The following example will illustrate the complete process of Example 2.

[0274] Taking frequency domain resources as BWP as an example:

[0275] Step 1: When the terminal is activated in the first serving cell, the terminal activates Z BWPs in the third frequency domain resource group of the serving cell, where Z is a positive integer.

[0276] Step 2: While the first serving cell is in an active state, the terminal receives a BWP activation command or a BWP switching command, instructing the terminal to activate these Z BWPs simultaneously. Alternatively, the network can flexibly activate one or more of the Z BWPs according to service requirements.

[0277] Step 3: When the terminal activates Z BWPs, it starts a BWP timer (i.e., the second timer). If data transmission occurs on at least one of the Z BWPs, the terminal restarts the BWP timer. When the BWP timer expires, the terminal deactivates the Z BWPs and activates the default BWP (i.e., all BWPs in the default frequency domain resource group) on this serving cell. Alternatively, when the terminal activates Z BWPs, this BWP timer is per BWP, meaning each BWP corresponds to one BWP timer (i.e., the third timer). When data transmission occurs on a BWP, the terminal restarts the BWP timer corresponding to that BWP. When a BWP timer expires, the terminal deactivates the BWP corresponding to that BWP timer and activates the default BWP corresponding to that BWP. Alternatively, if the timers for the Z BWPs expire, only BWP deactivation is performed without switching to the default BWP. Alternatively, this behavior can also be determined by whether the network-side device has configured a default BWP for these Z BWPs.

[0278] For example, if there are special BWPs and regular BWPs on the first serving cell, the special BWP may be configured as the default BWP, while other regular BWPs may not be configured as the default BWP. When the timer of the special BWP expires, the terminal will switch the special BWP to the default BWP, while the timers of other regular BWPs will simply be deactivated when they expire.

[0279] Example 3: N frequency domain resources include M frequency domain resources and P frequency domain resources.

[0280] It should be noted that, for the case of N frequency domain resources, including M frequency domain resources and P frequency domain resources, the description of how the terminal activates frequency domain resources, deactivates frequency domain resources, starts timers, and stops timers can be found in the specific descriptions in Example 1 and Example 2, respectively. The embodiments of this application will not be repeated here.

[0281] Figure 10 A flowchart illustrating the frequency domain resource configuration method provided in an embodiment of this application is shown. Figure 10 As shown, the frequency domain resource configuration method provided in this application embodiment may include the following step 301.

[0282] Step 301: The network-side device sends the first configuration information to the terminal.

[0283] In this embodiment of the application, the first configuration information indicates N frequency domain resources, where N is a positive integer greater than 1.

[0284] In this embodiment, the aforementioned N frequency domain resources are used by the terminal for uplink transmission or downlink reception; the N frequency domain resources include at least one of the following:

[0285] M frequency domain resources, where M is a positive integer greater than 1, and these M frequency domain resources have not been configured to belong to any cell.

[0286] There are P frequency domain resources, which belong to the first cell and are located on different carriers, where P is a positive integer greater than 1.

[0287] It should be noted that the descriptions of the first configuration information, N frequency domain resources, M frequency domain resources, and P frequency domain resources mentioned above can be found in the specific descriptions in the above embodiments, and will not be repeated here in the embodiments of this application.

[0288] In some embodiments of this application, the first configuration information mentioned above includes: M first identifiers, each first identifier being used by the terminal to uniquely identify a frequency domain resource from the M frequency domain resources.

[0289] Thus, since the first configuration information sent by the network-side device to the terminal includes M first identifiers for the terminal to uniquely identify the M frequency domain resources from the M frequency domain resources, instead of sending the cell identifier of the cell to which the frequency domain resource belongs and the identifier of the frequency domain resource in the cell as in related technologies, the complexity of the terminal in determining the M frequency domain resources can be simplified, thereby reducing the complexity of the terminal.

[0290] In some embodiments of this application, the M frequency domain resources mentioned above include initial frequency domain resources, which are frequency domain resources used for initial access.

[0291] Thus, since the M frequency domain resources include initial frequency domain resources, which are frequency domain resources used for initial access, that is, frequency domain resources that the network-side device has already configured for the terminal before the network-side device sends the first configuration information, the network-side device can configure only M-1 frequency domain resources in the first configuration information. In other words, the network-side device can configure only a small number of frequency domain resources in the first configuration information, thereby reducing the amount of information in the first configuration information. In this way, the transmission resource overhead of the network-side device can be reduced.

[0292] In some embodiments of this application, when a first condition is met, the M frequency domain resources include an initial frequency domain resource; wherein the first condition includes at least one of the following: the first configuration information includes first indication information, which is used to indicate that the initial frequency domain resource is a dedicated frequency domain resource of the terminal; the first configuration information is used to configure M-1 frequency domain resources, and the number of the M-1 frequency domain resources is less than the maximum number of frequency domain resources that the terminal can configure, and the initial frequency domain resource is not included in the M-1 frequency domain resources.

[0293] Thus, on the one hand, since the M frequency domain resources may include the initial frequency domain resources already configured for the terminal by the network-side device, the network-side device can configure only a smaller number of M-1 frequency domain resources in the first configuration information and carry a smaller amount of first indication information in the first configuration information, thereby reducing the amount of information in the first configuration information. On the other hand, since the network-side device can also explicitly or implicitly indicate to the terminal whether the initial frequency domain resources are included in the M frequency domain resources by whether the first condition is met, the possibility of the terminal identifying initial frequency domain resources that are not needed by the network-side device as frequency domain resources in the M frequency domain resources can be reduced. In this way, while reducing the transmission resource overhead of the network-side device, it can be ensured that the terminal can perform uplink transmission or downlink reception based on the frequency domain resources required by the network-side device.

[0294] In some embodiments of this application, the state of each of the above N frequency domain resources includes an active state or a deactivated state; the initial state of each of the above M frequency domain resources is indicated by the network-side device or agreed upon by the protocol.

[0295] Thus, since the embodiments of this application specify the possible states of each frequency domain resource, and the state of each frequency domain resource among the M frequency domain resources can be determined by the network-side device or by the protocol, the network-side device can accurately indicate to the terminal or determine the initial state of each frequency domain resource through the protocol, and accurately determine the state of each frequency domain resource based on the initial state of each frequency domain resource, and accurately communicate with the terminal on the frequency domain resources that are in the active state among the N frequency domain resources, thereby improving the reliability of the network-side device's communication.

[0296] This application provides a frequency domain resource configuration method. A network-side device can send first configuration information to a terminal, indicating N frequency domain resources, so that the terminal can perform uplink transmission or downlink reception on the active frequency domain resources among the N frequency domain resources, where N is a positive integer greater than 1. The N frequency domain resources include at least one of the following: M frequency domain resources, where the M frequency domain resources are not configured to belong to any cell, where M is a positive integer greater than 1; and P frequency domain resources, where the P frequency domain resources belong to a first cell and are located on different carriers, where P is a positive integer greater than 1. Since the network-side device can send the first configuration information to the terminal, and the N frequency domain resources indicated by the first configuration information include M frequency domain resources that are not configured to belong to any cell, the network-side device can directly configure the frequency domain resources of multiple cells as M frequency domain resources without needing to configure the cells to which these M frequency domain resources belong. Thus, frequency domain resources distributed across multiple carriers in CA and multiple frequency domain resources on a single carrier in the BWP framework can use the same signaling framework, reducing the complexity of terminals, network-side equipment, and protocols. And / or, since the network-side equipment can send first configuration information to the terminal, and the N frequency domain resources indicated by this first configuration information include P frequency domain resources belonging to the same cell (i.e., the first cell) but located on different carriers, the network-side equipment can configure frequency domain resources on different carriers as frequency domain resources within a single virtual cell (i.e., the first cell), thereby simplifying baseband complexity and reducing storage / computing resource overhead. Furthermore, the network-side equipment can use the first configuration information to trigger the terminal to simultaneously perform uplink transmission or downlink reception on multiple frequency domain resources among the P frequency domain resources. This can also be understood as multiple frequency domain resources among the P frequency domain resources being activated simultaneously, rather than being limited to only one frequency domain resource being activated in a single cell at the same time, thereby reducing signaling overhead.

[0297] The following three different examples illustrate the specific schemes by which network-side devices instruct terminals to perform operations related to frequency domain resources.

[0298] Example 4: N frequency domain resources include M frequency domain resources.

[0299] In some embodiments of this application, the frequency domain resource configuration method provided in this application may further include the following step 401.

[0300] Step 401: The network-side device sends a second instruction message to the terminal.

[0301] In this embodiment of the application, the second indication information is used to indicate whether to activate the first frequency domain resource among the M frequency domain resources, or to deactivate the first frequency domain resource.

[0302] Thus, since the network-side device can send a second indication message to the terminal to indicate which frequency domain resources the network-side device needs the terminal to activate / deactivate, the terminal can accurately activate the frequency domain resources that the network-side device needs to activate / deactivate, thereby meeting the terminal's diverse needs such as data transmission or energy saving.

[0303] In some embodiments of this application, the frequency domain resource configuration method provided in this application may further include the following step 402.

[0304] Step 402: The network-side device sends a third instruction message to the terminal.

[0305] In this embodiment of the application, the aforementioned third indication information is used to indicate that the second frequency domain resource among the M frequency domain resources and the third frequency domain resource among the M frequency domain resources cannot be in an active state at the same time.

[0306] Thus, since the network-side device can send a third indication message to the terminal to indicate a third frequency domain resource that cannot be active at the same time as the second frequency domain resource, without requiring protocol specification, the complexity of the protocol can be reduced.

[0307] In some embodiments of this application, the M frequency domain resources mentioned above include a fourth frequency domain resource. In some examples, the frequency domain resource configuration method provided in the embodiments of this application may further include the following step 403.

[0308] Step 403: The network-side device sends the second configuration information to the terminal.

[0309] In this embodiment of the application, the second configuration information is used to configure a first timer, which is used to periodically trigger the deactivation of the fourth frequency domain resource.

[0310] Thus, since the network-side device can send the second configuration information to the terminal to configure the first timer for the terminal, the first timer is started when the fourth frequency domain resource is activated, and the fourth frequency domain resource is activated when the first timer expires, that is, when the terminal has not performed uplink transmission or downlink reception on the fourth frequency domain resource for a long time. Therefore, the power consumption of the terminal can be reduced.

[0311] In some embodiments of this application, the M frequency domain resources mentioned above include a fourth frequency domain resource. In some examples, the frequency domain resource configuration method provided in embodiments of this application may further include the following step 404.

[0312] Step 404: The network-side device sends third configuration information to the terminal.

[0313] In this embodiment of the application, the third configuration information is used to configure at least one of the following: the fifth frequency domain resource among the M frequency domain resources associated with the fourth frequency domain resource, and the special frequency domain resource among the M frequency domain resources.

[0314] Thus, since the network-side device can send third configuration information to the terminal to configure the terminal with the fifth frequency domain resource and / or the special frequency domain resource among the M frequency domain resources associated with the fourth frequency domain resource, the terminal can activate the fifth frequency domain resource or the special frequency domain resource when deactivating the fourth frequency domain resource. Therefore, the situation where the terminal does not have an active frequency domain resource due to the deactivation of the fourth frequency domain resource can be reduced, thereby reducing the situation where the network-side device cannot communicate with the terminal, thus improving the reliability of communication.

[0315] It should be noted that for a complete description of the process in Example 4, please refer to the specific description in Example 1 above. The embodiments of this application will not be repeated here.

[0316] Example 5: N frequency domain resources include P frequency domain resources.

[0317] In some embodiments of this application, the aforementioned N frequency domain resources further include X frequency domain resources of the first cell, which are different from the P frequency domain resources, where X is a natural number. In some examples, the frequency domain resource configuration method provided in the embodiments of this application may also include the following step 405.

[0318] Step 405: The network-side device sends the fourth configuration information to the terminal.

[0319] In this embodiment of the application, the fourth configuration information is used to indicate Y frequency domain resource groups, each of which includes at least one frequency domain resource from X frequency domain resources and P frequency domain resources, where Y is a positive integer.

[0320] In some embodiments of this application, the aforementioned Y frequency domain resource groups satisfy at least one of the following:

[0321] Determined by the capabilities of the terminal;

[0322] Determined by the service type of the terminal;

[0323] It is determined by the terminal type.

[0324] Therefore, since the Y frequency domain resource groups can be determined by the terminal's capabilities and / or by the terminal's service type and / or by the terminal's terminal type, the network-side device can directly instruct the terminal to activate all frequency domain resources in a certain frequency domain resource group according to needs, without having to determine and instruct the terminal to activate them one by one from the X and P frequency domain resources. This reduces the complexity of the network-side device instructing the terminal to activate frequency domain resources, thus reducing the complexity of the terminal.

[0325] In some embodiments of this application, the fourth configuration information described above is also used for the terminal to activate frequency domain resources (e.g., at least some frequency domain resources) in the Y frequency domain resource groups.

[0326] Therefore, since the network-side device can send fourth configuration information to the terminal to indicate Y frequency domain resource groups, the terminal can activate frequency domain resources in the Y frequency domain resource groups based on this fourth configuration information. That is, it can activate and deactivate frequency domain resources at the granularity of frequency domain resource groups. Therefore, the network-side device does not need to indicate the activated or deactivated frequency domain resources one by one, which helps to reduce signaling overhead.

[0327] In some embodiments of this application, the frequency domain resource configuration method provided in this application may further include the following step 406.

[0328] Step 406: The network-side device sends the fourth instruction information to the terminal.

[0329] In this embodiment of the application, the aforementioned fourth indication information is used to indicate the first frequency domain resource group among the Y frequency domain resource groups; the first frequency domain resource group is the frequency domain resource group activated by the terminal when activating the first cell.

[0330] Thus, since the network-side device can send a fourth indication message to the terminal to indicate the first frequency domain resource group required by the network-side device, when the first cell is activated, the terminal immediately activates all frequency domain resources of the first frequency domain resource group of the first cell, thereby meeting the data transmission requirements.

[0331] In some embodiments of this application, the frequency domain resource configuration method provided in this application may further include the following step 407.

[0332] Step 407: The network-side device sends the fifth instruction information to the terminal.

[0333] In this embodiment of the application, the fifth instruction information is used to instruct the activation of all frequency domain resources in the second frequency domain resource group of the Y frequency domain resource groups, or to deactivate all frequency domain resources in the second frequency domain resource group of the Y frequency domain resource groups.

[0334] Thus, since the network-side device can send a fifth indication message to the terminal, indicating the second frequency domain resource group required by the network-side device through the fifth indication message, the terminal can accurately activate or deactivate all frequency domain resources in the second frequency domain resource group required by the network-side device.

[0335] In some embodiments of this application, the aforementioned Y frequency domain resource groups include a third frequency domain resource group. In some examples, the frequency domain resource configuration method provided in embodiments of this application may further include the following step 408.

[0336] Step 408: The network-side device sends the fifth configuration information to the terminal.

[0337] In this embodiment of the application, the fifth configuration information is used to configure a second timer, which is used to periodically trigger the deactivation of all frequency domain resources in the third frequency domain resource group.

[0338] Therefore, since the network-side device can send fifth configuration information to the terminal to configure the second timer, the terminal can start the second timer when activating all frequency resources in the third frequency resource group. When the second timer expires—that is, when the terminal has not performed uplink transmission or downlink reception on any frequency resource in the third frequency resource group for an extended period—the terminal can then activate all frequency resources in the third frequency resource group. This reduces the terminal's power consumption. Thus, terminal communication performance can be improved while reducing terminal power consumption.

[0339] In some embodiments of this application, the frequency domain resource configuration method provided in this application may further include the following step 409.

[0340] Step 409: The network-side device sends the sixth configuration information to the terminal.

[0341] In this embodiment of the application, the sixth configuration information is used to configure the default frequency domain resource group among the Y frequency domain resource groups. The default frequency domain resource group is the frequency domain resource group that the terminal activates when deactivating all frequency domain resources in the third frequency domain resource group.

[0342] The frequency domain resource configuration method provided in this application can be executed by a frequency domain resource configuration device. This application uses the execution of the frequency domain resource configuration method by a frequency domain resource configuration device as an example to illustrate the frequency domain resource configuration device provided in this application.

[0343] This application provides a frequency domain resource configuration device. As an example, the frequency domain resource configuration device can be a communication device or a component in a communication device, such as a chip. The communication device can be a terminal, a network-side device, or a server, etc. Exemplarily, the terminal can be, but is not limited to, the type of terminal 11 listed above, and the network-side device can be, but is not limited to, the type of network-side device 12 listed above. This application does not impose specific limitations.

[0344] The frequency domain resource configuration device includes a receiving module, a transmitting module, and a processing module. These modules can be implemented in software or hardware. When implemented in hardware, the processing module can be implemented by a processor. Exemplarily, the processor can include general-purpose processors, special-purpose processors, such as a Central Processing Unit (CPU), microprocessor, Digital Signal Processor (DSP), Artificial Intelligence (AI) processor, Graphics Processing Unit (GPU), Application Specific Integrated Circuit (ASIC), Network Processor (NP), Field Programmable Gate Array (FPGA), or other programmable logic devices, gate circuits, transistors, discrete hardware components, etc. The receiving and transmitting modules can be implemented by a communication interface, which can include one or more of the following: transceiver, pins, circuits, bus, radio frequency unit, etc.

[0345] Specifically, see Figure 11 When the frequency domain resource configuration device is a terminal or a component within a terminal, the frequency domain resource configuration device 500 includes a receiving module 501, configured to receive first configuration information sent by a network-side device. This first configuration information indicates N frequency domain resources, where N is a positive integer greater than 1. The receiving module 501 is further configured to perform uplink transmission on the active frequency domain resources among the N frequency domain resources according to the first configuration information; or, the sending module 502 is further configured to perform downlink reception on the active frequency domain resources among the N frequency domain resources according to the first configuration information received by the receiving module 501. The aforementioned N frequency domain resources include at least one of the following: M frequency domain resources, where the M frequency domain resources are not configured to belong to a specific cell, where M is a positive integer greater than 1; and P frequency domain resources, where the P frequency domain resources belong to a first cell and are located on different carriers, where P is a positive integer greater than 1.

[0346] This application provides a frequency domain resource configuration device. Since the frequency domain resource configuration device can receive first configuration information sent by a network-side device, and the first configuration information indicates N frequency domain resources including M frequency domain resources of cells not yet configured, the network-side device can directly configure the frequency domain resources of multiple cells into M frequency domain resources without configuring the cells to which these M frequency domain resources belong. Thus, frequency domain resources distributed across multiple carriers in CA and multiple frequency domain resources on a single carrier in the BWP framework can use the same signaling framework, reducing the complexity of the frequency domain resource configuration device, network-side device, and protocol. And / or, since the frequency domain resource configuration device can receive the first configuration information sent by the network-side device, and the first configuration information indicates N frequency domain resources including P frequency domain resources belonging to the same cell (i.e., the first cell) but located on different carriers, the network-side device can configure frequency domain resources on different carriers into frequency domain resources within a single virtual cell (i.e., the first cell), thereby simplifying baseband complexity and reducing storage / computing resource overhead. Furthermore, the frequency domain resource configuration device can simultaneously perform uplink transmission or downlink reception on multiple frequency domain resources among the P frequency domain resources. This can also be understood as multiple frequency domain resources among the P frequency domain resources being activated simultaneously, rather than being limited to only one frequency domain resource being activated in a cell at the same time, thereby reducing signaling overhead.

[0347] In one possible implementation, the first configuration information includes M first identifiers, each first identifier being used by the frequency domain resource configuration device 500 to uniquely identify a frequency domain resource from the M frequency domain resources.

[0348] In one possible implementation, the M frequency domain resources mentioned above include an initial frequency domain resource, which is a frequency domain resource used for initial access.

[0349] In one possible implementation, under the condition that a first condition is met, the M frequency domain resources include an initial frequency domain resource; wherein the first condition includes at least one of the following: the first configuration information includes first indication information, which is used to indicate that the initial frequency domain resource is a dedicated frequency domain resource of the frequency domain resource configuration device 500; the first configuration information is used to configure M-1 frequency domain resources, and the number M-1 of the M-1 frequency domain resources is less than the maximum number of frequency domain resources that the frequency domain resource configuration device 500 can configure, and the M-1 frequency domain resources do not include the initial frequency domain resource.

[0350] In one possible implementation, the state of each of the N frequency domain resources includes an active state or a deactivated state; the initial state of each of the M frequency domain resources is indicated by the network-side device or agreed upon by the protocol.

[0351] In one possible implementation, the receiving module 501 is further configured to receive second indication information sent by the network-side device. This second indication information is used to indicate the activation or deactivation of a first frequency domain resource among the M frequency domain resources. The frequency domain resource configuration device 500 provided in this embodiment further includes a processing module 503, configured to activate the first frequency domain resource according to the second indication information received by the receiving module 501 when the second indication information indicates activation; or, configured to deactivate the first frequency domain resource according to the second indication information received by the receiving module 501 when the second indication information indicates deactivation.

[0352] In one possible implementation, the frequency domain resource configuration device 500 provided in this application embodiment further includes a processing module 503, which is used to activate a third frequency domain resource among the M frequency domain resources when the frequency domain resource configuration device 500 determines that a second frequency domain resource among the M frequency domain resources needs to be activated; wherein the third frequency domain resource is a frequency domain resource in an active state, and the third frequency domain resource and the second frequency domain resource cannot be in an active state at the same time.

[0353] In one possible implementation, the receiving module 501 is further configured to receive third indication information sent by the network-side device, the third indication information indicating that the second frequency domain resource and the third frequency domain resource cannot be active simultaneously. The processing module 503 is specifically configured to activate the third frequency domain resource according to the third indication information.

[0354] In one possible implementation, the aforementioned M frequency domain resources include a fourth frequency domain resource. The receiving module 501 receives second configuration information sent by the network-side device. This second configuration information is used to configure a first timer, which is used to periodically trigger the deactivation of the fourth frequency domain resource. The frequency domain resource configuration device 500 provided in this embodiment further includes a processing module 503, used to start the first timer when the frequency domain resource configuration device 500 activates the fourth frequency domain resource, based on the second configuration information received by the receiving module 501; and during the operation of the first timer, if the frequency domain resource configuration device 500 receives first downlink control information sent by the network-side device, then restart the first timer. This first downlink control information is used to schedule the frequency domain resource configuration device 500 to perform uplink transmission or downlink reception on the fourth frequency domain resource; and when the first timer times out, deactivate the fourth frequency domain resource.

[0355] In one possible implementation, the receiving module 501 is further configured to receive third configuration information sent by the network-side device. This third configuration information is used to configure at least one of the following: a fifth frequency domain resource among the M frequency domain resources associated with the fourth frequency domain resource, and a special frequency domain resource among the M frequency domain resources. The processing module 503 is specifically configured to: start a first timer if the third configuration information is used to configure a special frequency domain resource and the fourth frequency domain resource is not a special frequency domain resource; start a first timer if the third configuration information is used to configure a fifth frequency domain resource associated with the fourth frequency domain resource; start a first timer if the third configuration information is used to configure a special frequency domain resource, the fourth frequency domain resource is a special frequency domain resource, and the fourth frequency domain resource is not the only currently active frequency domain resource in the frequency domain resource configuration device 500.

[0356] In one possible implementation, the receiving module 501 is further configured to receive third configuration information sent by the network-side device. This third configuration information is used to configure at least one of the following: a fifth frequency domain resource among the M frequency domain resources associated with the fourth frequency domain resource, and a special frequency domain resource among the M frequency domain resources. The processing module 503 is further configured to: if the third configuration information is used to configure a special frequency domain resource, then upon the expiration of the first timer, activate the special frequency domain resource according to the third configuration information; or, if the third configuration information is used to configure a special frequency domain resource, and the frequency domain resource configuration device 500 currently has no active frequency domain resource upon the expiration of the first timer, then activate the special frequency domain resource according to the third configuration information upon the expiration of the first timer; or, if the third configuration information is used to configure a fifth frequency domain resource associated with the fourth frequency domain resource, then upon the expiration of the first timer, activate the fifth frequency domain resource according to the third configuration information.

[0357] In one possible implementation, the processing module 503 is further configured to: start a first timer if the fourth frequency domain resource is not the only frequency domain resource currently active in the frequency domain resource configuration device 500 when it is activated; and stop the first timer if the fourth frequency domain resource is the only frequency domain resource currently active in the frequency domain resource configuration device 500 during the operation of the first timer.

[0358] In one possible implementation, the aforementioned N frequency domain resources further include X frequency domain resources of the first cell, which are different from the P frequency domain resources, where X is a natural number. The receiving module 501 is also configured to receive fourth configuration information sent by the network-side device. This fourth configuration information indicates Y frequency domain resource groups, each of which includes at least one frequency domain resource from a plurality of frequency domain resources, including X and P frequency domain resources, where Y is a positive integer. The frequency domain resource configuration device 500 provided in this application embodiment may further include a processing module 503, configured to activate the frequency domain resources in the Y frequency domain resource groups according to the fourth configuration information received by the receiving module 501.

[0359] In one possible implementation, the processing module 503 is specifically used to activate all frequency domain resources in the first frequency domain resource group among the Y frequency domain resource groups when the first cell is activated.

[0360] In one possible implementation, the receiving module 501 is further configured to receive fourth indication information sent by the network-side device, the fourth indication information being used to indicate the first frequency domain resource group. The processing module 503 is specifically configured to activate all frequency domain resources in the first frequency domain resource group according to the fourth indication information.

[0361] In one possible implementation, the receiving module 501 is further configured to receive a fifth indication message sent by the network-side device. This fifth indication message indicates whether to activate or deactivate all frequency domain resources in the second frequency domain resource group within the Y frequency domain resource groups. Specifically, the processing module 503 is configured to activate all frequency domain resources in the second frequency domain resource group according to the fifth indication message when the fifth indication message indicates activation; or, if the fifth indication message indicates deactivation, deactivate all frequency domain resources in the second frequency domain resource group according to the fifth indication message.

[0362] In one possible implementation, the aforementioned Y frequency domain resource groups include a third frequency domain resource group. The receiving module 501 is further configured to receive fifth configuration information sent by the network-side device. This fifth configuration information is used to configure a second timer, which is used to periodically trigger the deactivation of all frequency domain resources in the third frequency domain resource group. The processing module 503 is further configured to, based on the fifth configuration information received by the receiving module 501, start the second timer when the frequency domain resource configuration device 500 activates all frequency domain resources in the third frequency domain resource group; and during the operation of the second timer, if the frequency domain resource configuration device 500 receives second downlink control information sent by the network-side device, restart the second timer based on the second downlink control information. This second downlink control information is used to schedule the frequency domain resource configuration device 500 to perform uplink transmission or downlink reception on at least some frequency domain resources in the third frequency domain resource group; and when the second timer expires, deactivate all frequency domain resources in the third frequency domain resource group.

[0363] In one possible implementation, the receiving module 501 is further configured to receive sixth configuration information sent by the network-side device, which is used to configure the default frequency domain resource group among the Y frequency domain resource groups. The processing module 503 is further configured to activate all frequency domain resources in the default frequency domain resource group when the second timer expires, based on the sixth configuration information received by the receiving module 501.

[0364] In one possible implementation, the aforementioned Y frequency domain resource groups satisfy at least one of the following: determined by the capabilities of the frequency domain resource configuration device 500; determined by the service type of the frequency domain resource configuration device 500; determined by the terminal type of the frequency domain resource configuration device 500.

[0365] See Figure 12 When the frequency domain resource configuration device is a network-side device or a component of a network-side device, the frequency domain resource configuration device 600 includes a transmission module 601, used to send first configuration information to the terminal. The first configuration information indicates N frequency domain resources, where N is a positive integer greater than 1. The N frequency domain resources are used by the terminal for uplink transmission or downlink reception. The N frequency domain resources include at least one of the following: M frequency domain resources, where the M frequency domain resources are not configured to belong to any cell, where M is a positive integer greater than 1; and P frequency domain resources, where the P frequency domain resources belong to the first cell and the carriers of the P frequency domain resources are different, where P is a positive integer greater than 1.

[0366] This application provides a frequency domain resource configuration device. Since the frequency domain resource configuration device can send first configuration information to the terminal, and the first configuration information indicates N frequency domain resources including M frequency domain resources of cells not yet configured, the frequency domain resource configuration device can directly configure the frequency domain resources of multiple cells into M frequency domain resources without configuring the cells to which these M frequency domain resources belong. Thus, frequency domain resources distributed across multiple carriers in CA and multiple frequency domain resources on a single carrier in the BWP framework can use the same signaling framework, reducing the complexity of the terminal, the frequency domain resource configuration device, and the protocol. And / or, since the frequency domain resource configuration device can send first configuration information to the terminal, and the first configuration information indicates N frequency domain resources including P frequency domain resources belonging to the same cell (i.e., the first cell) but located on different carriers, the frequency domain resource configuration device can configure frequency domain resources on different carriers into frequency domain resources within a single virtual cell (i.e., the first cell), thereby simplifying baseband complexity and reducing storage / computing resource overhead. Furthermore, the frequency domain resource configuration device can trigger the terminal to simultaneously perform uplink transmission or downlink reception on multiple frequency domain resources among the P frequency domain resources through the first configuration information. This can also be understood as multiple frequency domain resources among the P frequency domain resources being activated simultaneously, rather than being limited to only one frequency domain resource being activated in a cell at the same time, thereby reducing signaling overhead.

[0367] In one possible implementation, the first configuration information mentioned above includes: M first identifiers, each first identifier being used by the terminal to uniquely identify a frequency domain resource from the M frequency domain resources.

[0368] In one possible implementation, the M frequency domain resources mentioned above include an initial frequency domain resource, which is a frequency domain resource used for initial access.

[0369] In one possible implementation, under the condition that the first condition is met, the M frequency domain resources include the initial frequency domain resources; wherein the first condition includes at least one of the following: the first configuration information includes first indication information, which is used to indicate that the initial frequency domain resources are dedicated frequency domain resources of the terminal; the first configuration information is used to configure M-1 frequency domain resources, and the number of the M-1 frequency domain resources is less than the maximum number of frequency domain resources that can be configured by the terminal, and the initial frequency domain resources are not included in the M-1 frequency domain resources.

[0370] In one possible implementation, the state of each of the N frequency domain resources includes an active state or a deactivated state; the initial state of each of the M frequency domain resources is indicated by the frequency domain resource configuration device or agreed upon by the protocol.

[0371] In one possible implementation, the sending module 601 is further configured to send a second indication information to the terminal, the second indication information being used to indicate the activation of a first frequency domain resource among the M frequency domain resources, or the deactivation of the first frequency domain resource.

[0372] In one possible implementation, the sending module 601 is further configured to send a third indication information to the terminal, the third indication information being used to indicate that the second frequency domain resource among the M frequency domain resources and the third frequency domain resource among the M frequency domain resources cannot be in an active state at the same time.

[0373] In one possible implementation, the aforementioned M frequency domain resources include a fourth frequency domain resource. The aforementioned sending module 601 is further configured to send second configuration information to the terminal, the second configuration information being used to configure a first timer, the first timer being used to periodically trigger the deactivation of the fourth frequency domain resource.

[0374] In one possible implementation, the sending module 601 is further configured to send third configuration information to the terminal, the third configuration information being configured to configure at least one of the following: the fifth frequency domain resource among the M frequency domain resources associated with the fourth frequency domain resource, and the special frequency domain resource among the M frequency domain resources.

[0375] In one possible implementation, the aforementioned N frequency domain resources further include X frequency domain resources of the first cell, which are different from the P frequency domain resources, where X is a natural number. The aforementioned sending module 601 is also configured to send fourth configuration information to the terminal, which indicates Y frequency domain resource groups, each of which includes at least one frequency domain resource from the X and P frequency domain resources, where Y is a positive integer.

[0376] In one possible implementation, the sending module 601 is further configured to send a fourth indication information to the terminal, the fourth indication information being used to indicate a first frequency domain resource group among the Y frequency domain resource groups; wherein, the first frequency domain resource group is the frequency domain resource group activated by the terminal when activating the first cell.

It is understood that the aforementioned modem processor may also not be integrated into processor 810.

[0389] The radio frequency unit 801 is configured to receive first configuration information sent by the network-side device, the first configuration information indicating N frequency domain resources, where N is a positive integer greater than 1; and to perform uplink transmission or downlink reception on the active frequency domain resources among the N frequency domain resources according to the first configuration information. The aforementioned N frequency domain resources include at least one of the following: M frequency domain resources, where the M frequency domain resources are not configured to belong to a cell, where M is a positive integer greater than 1; and P frequency domain resources, where the P frequency domain resources belong to the first cell and are located on different carriers, where P is a positive integer greater than 1.

[0390] This application provides a terminal that can receive first configuration information sent by a network-side device. The first configuration information indicates N frequency domain resources, including M frequency domain resources from cells that are not currently configured to belong to. This means the network-side device can directly configure the frequency domain resources of multiple cells into M frequency domain resources without needing to configure the cells to which these M frequency domain resources belong. Thus, frequency domain resources distributed across multiple carriers in CA and multiple frequency domain resources on a single carrier in the BWP framework can use the same signaling framework, reducing the complexity of the terminal, network-side device, and protocol. And / or, since the terminal can receive the first configuration information sent by the network-side device, and the first configuration information indicates N frequency domain resources, including P frequency domain resources belonging to the same cell (i.e., the first cell) but located on different carriers, the network-side device can configure frequency domain resources on different carriers into frequency domain resources within a single virtual cell (i.e., the first cell), thereby simplifying baseband complexity and reducing storage / computing resource overhead. Furthermore, the terminal can simultaneously perform uplink transmission or downlink reception on multiple frequency domain resources among the P frequency domain resources. This can also be understood as multiple frequency domain resources among the P frequency domain resources being activated at the same time, rather than being limited to only one frequency domain resource being activated in a cell at the same time, thereby reducing signaling overhead.
