[0034] To make the application purposes, technical solutions and advantages of the present application more clear, the embodiments of the present application are described below with reference to the drawings, and it should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other in any manner without conflict.

[0035] In 5G system, the concept of BWP is proposed and widely used. BWP is a continuous frequency domain resource in frequency domain. Up to four downlink BWPs can be configured for a UE. The bandwidth of each BWP should be equal to or greater than the bandwidth of the synchronization signal block (SSB), but it can contain SSB or not. Only one BWP can be active at a given time, and the UE is not expected to receive physical downlink shared channel (PDSCH), physical downlink control channel (PDCCH), channel state information-reference signal (CSI-RS) or tracking reference signal (TRS) outside the active BWP.

[0036] Similarly, up to four uplink BWPs can be configured for a UE. Only one BWP can be active at a given time. If the UE is configured with a supplementary uplink, the UE can also be configured with up to four carrier bandwidth parts in the supplementary uplink. Only one BWP can be active at a given time, and the UE must not transmit physical uplink shared channel (PUSCH) or physical uplink control channel (PUCCH) outside the active BWP.

[0037] Switching between multiple BWPs can be achieved. Switching can be achieved through radio resource control (RRC) configuration, timer triggering, or downlink control information (DCI) indication.

[0038] Currently, the switching of frequency domain resources is implemented through BWP switching. Different BWPs have different frequency domain resources, PDCCH monitoring occasions, and / or maximum multiple-input multiple-output (MIMO) layer configurations. Energy saving can be achieved through BWP switching. For example, switching to a BWP with a small bandwidth or a BWP with a small maximum MIMO layer number can achieve the effect of UE power saving. There are multiple ways for existing BWP switching, such as RRC configuration / reconfiguration, timer-based BWP switching, and DCI indication. However, there is a switching delay (for example, 1 ms, 0.75 ms, or 3 ms) when switching the BWP, which will result in the inability to quickly switch the BWP according to the demand in the data scheduling process, affecting the data scheduling efficiency and the UE energy saving effect.

[0039] FIG. 1 is a flowchart of a frequency domain resource determination method provided by an embodiment of the present application. As shown in FIG. 1, the frequency domain resource determination method provided by the embodiment of the present application includes the following steps.

[0040] In step S110, configuration information sent by a second node is received. The configuration information includes a frequency domain resource set configuration. The frequency domain resource set includes multiple frequency domain resources. The multiple frequency domain resources have an association relationship. The multiple frequency domain resources are continuous in the frequency domain or discrete in the frequency domain.

[0041] The frequency domain resource determination method provided by the embodiment is applied to a first node in a mobile communication network. The first node can be a UE in the mobile communication network or a terminal-side device or node in other mobile communication networks. The first node performs data transmission or reception in the mobile communication network according to the scheduling of a second node. The second node is a base station or other device or node on the base station side in the mobile communication network. The resources used by the first node for data transmission in the mobile communication network are scheduled by the second node.

[0042] In this embodiment, the first node receives configuration information sent by the second node, which includes a frequency domain resource set configuration. The frequency domain resource set configuration is used to configure the relevant configuration information of a frequency domain resource set including multiple frequency domain resources. The first node can receive the configuration information sent by the second node via a downlink control message, which can be any type of control information sent by the second node to the first node, such as DCI or RRC. The frequency domain resource set configured by the frequency domain resource set configuration includes multiple frequency domain resources, which are associated and can be continuous or discrete in the frequency domain. The configuration information is used to configure a frequency domain resource set for the first node, which includes multiple frequency domain resources allocated to the first node, and these multiple frequency domain resources are associated. The multiple frequency domain resources can be continuous or discontinuous in the frequency domain. In this embodiment, BWP is used as an example for illustration.

[0043] Multiple frequency domain resources in a frequency domain resource set can be multiple frequency domain resources in a frequency domain resource group, or multiple frequency domain resources with an association relationship. For example, the frequency domain resource set includes at least one first-type frequency domain resource and at least one second-type frequency domain resource, and the first-type and second-type frequency domain resources are associated with each other. Here, "association" can be configuring an associated frequency domain resource identifier or a frequency domain resource group identifier in the parameter configuration of the associated frequency domain resource. In some embodiments, "association" is configuring an associated frequency domain resource identifier in the parameter configuration of a frequency domain resource. The first-type frequency domain resource can be a parent frequency domain resource but cannot be a child frequency domain resource, while the second-type frequency domain resource can be both a parent and a child frequency domain resource. At least one child frequency domain resource is associated with a parent frequency domain resource; the state of at least one child frequency domain resource is determined based on the state of the associated parent frequency domain resource.

[0044] Step S120: Determine one or more active frequency domain resources in the frequency domain resource set.

[0045] The configuration information received by the first node indicates that one or more frequency domain resources in the configured frequency domain resource set can be active. After receiving the configuration information, the first node can determine one or more active frequency domain resources in the frequency domain resource set. One or more active frequency domain resources can be active simultaneously. The state of a frequency domain resource can include active or inactive states, and multiple frequency domain resources in the set can be active and / or inactive. Active states can include dormant, power-saving, or normal states. Defining multiple states is to achieve rapid switching from small to large frequency domain bandwidths. By switching the states of various frequency domain resources, multiple small frequency domain bandwidths can be combined into a large frequency domain bandwidth.

[0046] In this context, the frequency domain resources in the dormant state can be configured to ignore / deactivate / disable PDCCH-related settings. The first node does not perform blind PDCCH detection / listening in the frequency domain resources during the dormant state. In some embodiments, Channel State Information (CSI) measurements and / or CSI reporting can be performed during the dormant state. These CSI measurements and / or CSI reporting are periodic.

[0047] In some embodiments, during the sleep state, the corresponding uplink frequency domain resources can be used for Sounding Reference Signal (SRS) transmission. In some embodiments, the SRS transmission period is longer in the sleep state than in the normal state. In some embodiments, the SRS frequency domain is sparser in the sleep state. For example, in the sleep state, every 8 resource blocks (RBs) constitute one SRS frequency domain resource, while in the normal state, every 2 RBs constitute one SRS frequency domain resource.

[0048] In some embodiments, during the uplink frequency domain resource sleep state, the first node has at least one of the following characteristics: does not send a scheduling request (SR), does not send a buffer status report (BSR), does not perform a random access channel (RACH) (e.g., does not send Msg 1), does not send configured grant (CG) data, and does not send an acknowledgment / negative acknowledgment (ACK-NACK).

[0049] In some embodiments, the sleep state can be divided into a first sleep state and a second sleep state. In the first sleep state, the UE can perform CSI measurements and reporting. CSI reporting includes at least one of the following: Rank Indicator (RI), Layer Indicator (LI), CSI-RS Resource Indicator (CRI), Channel Quality Indication (CQI), and Precoding Matrix Indicator (PMI). In the second sleep state, the UE can perform RSRP and RSRQ measurements and reporting. The second sleep state is more power-efficient than the first sleep state. The sleep state described in this application embodiment can be either the first sleep state or the second sleep state. In some embodiments, the state of frequency domain resources can include at least one of the following: first sleep state, second sleep state, power-saving state, normal state, and deactivation state.

[0050] In some embodiments, signaling can be used to indicate the activation / deactivation of a frequency domain resource group (or a set of frequency domain resources). When a frequency domain resource group is activated, its first type of frequency domain resources are in a normal state, and the frequency domain resources associated with the first type of frequency domain resources are in one of the following states: a first sleep state, a sleep state, or a power-saving state. Other frequency domain resource states are in one of the following states: a second sleep state, or a deactivated state.

[0051] In some embodiments, when a frequency domain resource group is activated / enabled, its first type of frequency domain resource state is normal, and other frequency domain resource states are one of the following: first hibernation state, hibernation state, power saving state.

[0052] In some embodiments, when a frequency domain resource group is deactivated, all frequency domain resources are deactivated.

[0053] In some embodiments, the state of a frequency domain resource group includes at least one of the following: fully active, enabled, or deactivated.

[0054] When a frequency domain resource group is in an enabled / fully activated state, data scheduling can be performed within it.

[0055] The fully activated state is when all frequency domain resources within the frequency domain resource group are activated. In the deactivated state, data scheduling does not occur within that frequency domain resource group. The enabled state is when at least one frequency domain resource within the frequency domain resource group is activated.

[0056] In some embodiments, the state of a frequency domain resource includes: a normal state, a dormant state, and a deactivated state. In some embodiments, the state of a frequency domain resource includes: a normal state, a second dormant state, and a deactivated state. In some embodiments, the state of a frequency domain resource includes: a normal state, a first dormant state, and a deactivated state. In some embodiments, the state of a frequency domain resource includes: a normal state, a second dormant state, a first dormant state, and a deactivated state. In some embodiments, the state of a frequency domain resource includes: a normal state, a first dormant state, a power-saving state, and a deactivated state. In some embodiments, the state of a frequency domain resource includes: a normal state, a dormant state, a power-saving state, and a deactivated state.

[0057] The power-saving state and normal state of frequency domain resources can each correspond to a set of parameter configurations. In the power-saving state, the configuration corresponding to the power-saving state is used / enabled; in the normal state, the configuration corresponding to the normal state is used / enabled. The two sets of configurations cannot be activated / used simultaneously. In some embodiments, the frequency domain resources in the frequency domain resource set do not have a power-saving state, only a normal state. In some embodiments, the parameters of the power-saving state of uplink frequency domain resources satisfy one of the following: uplink discontinuous reception (DRX) is configured, the SR period is greater than the SR period of the normal state, the SRS period is greater than the SRS period of the normal state, the SR period is greater than the first parameter, and the SRS period is greater than the second parameter. The first parameter is 640 time slots or 5120 time slots. An SR period greater than the SR period of the normal state means that the SR period configured in the power-saving state is greater than the SR period configured in the normal state of the frequency domain resources. An SRS period greater than the SRS period of the normal state means that the SRS period configured in the power-saving state is greater than the SRS period configured in the normal state of the frequency domain resources. In some embodiments, the second parameter is 160 milliseconds or 2560 time slots.

[0058] For frequency domain resources that are inactive, the first node does not perform any operations on the inactive frequency domain resources.

[0059] Each frequency domain resource in the frequency domain resource set is in only one state at a time.

[0060] The switching delay between the active and inactive states of frequency domain resources is greater than the switching delay between each active state.

[0061] The switching delay of frequency domain resources between power-saving state and normal state is greater than the switching delay between power-saving state and sleep state.

[0062] The switching delay of frequency domain resources between power-saving state and normal state is less than or equal to the switching delay between power-saving state and sleep state.

[0063] The switching delay of frequency domain resources between power-saving state and normal state is less than or equal to the switching delay between normal state and sleep state.

[0064] The switching delay between power-saving and normal states for frequency domain resources is greater than the switching delay between normal and sleep states.

[0065] In some embodiments, the switching delay of frequency domain resources between power-saving state and normal state is 0 or 1 time slot.

[0066] In some embodiments, the switching delay between the frequency domain resource and the normal state is 0 or 1 time slot.

[0067] Within a set of frequency domain resources, multiple active frequency domain resources can form or be considered as a single active large frequency domain resource.

[0068] Step S130: Uplink data transmission or downlink data reception is performed on one or more active frequency domain resources.

[0069] After identifying one or more active frequency domain resources in the frequency domain resource set, the first node can then transmit uplink data or receive downlink data on those identified active frequency domain resources. The frequency domain resources configured in the frequency domain resource set by the configuration information received by the first node can be either frequency domain resources used for uplink data transmission or frequency domain resources used for downlink data reception.

[0070] In one embodiment, the PUSCH or PDSCH is transmitted on one active frequency domain resource, or the PUSCH or PDSCH is transmitted across multiple active frequency domain resources. That is, active frequency domain resources can be used individually or together to carry the data to be transmitted.

[0071] In 6G communication systems, where the maximum bandwidth can reach 800MHz, continuously activating a large bandwidth would lead to high power consumption, while using a small bandwidth would limit system transmission efficiency. Switching between large and small bandwidths could be time-consuming, hindering flexible resource scheduling based on service needs. Therefore, this application proposes the concept of a frequency domain resource set. This set includes multiple related frequency domain resources, forming a large bandwidth frequency domain resource. By leveraging the relationships between these resources, rapid adaptive adjustment of frequency domain resources can be achieved, enabling flexible switching between large and small bandwidths while maintaining energy efficiency, thereby increasing the flexibility of frequency domain resource scheduling.

[0072] Figure 2 is a schematic diagram of the frequency domain resource set in the frequency domain resource determination method provided in the embodiment of this application. The multiple associated frequency domain resources in the frequency domain resource set shown in Figure 2 are adjacent and do not overlap in the frequency domain. Figure 2 shows a frequency domain resource set composed of 7 frequency domain resources that are adjacent and do not overlap in the frequency domain.

[0073] In some embodiments, multiple associated frequency domain resources in a frequency domain resource set may be discrete in the frequency domain, i.e., discontinuous. Some frequency domain resource sets may have continuous frequency domain resources, while others may have discontinuous frequency domain resources.

[0074] In some embodiments, the states of multiple frequency domain resources in a frequency domain resource set are related. These multiple frequency domain resources can be divided into two categories: a first category of frequency domain resources and a second category of frequency domain resources. The first category of frequency domain resources are the associated frequency domain resources, also known as anchor frequency domain resources, while the second category of frequency domain resources are those associated with another frequency domain resource, also known as extended frequency domain resources. The frequency domain resource set includes at least one first category of frequency domain resources and at least one second category of frequency domain resources. Alternatively, the first category of frequency domain resources can be referred to as parent frequency domain resources, and the second category of frequency domain resources as child frequency domain resources. In some embodiments, the state of the first category of frequency domain resources does not change with changes in the associated frequency domain resources. The second category of frequency domain resources can be a parent frequency domain resource, a child frequency domain resource, or simultaneously a parent of one frequency domain resource and a child of another. A child frequency domain resource changes with the state of its associated parent frequency domain resource. The state of a parent frequency domain resource does not change with changes in the state of its associated child frequency domain resources. As shown in Figure 2, frequency domain resource 4 is a first-class frequency domain resource, and the others are second-class frequency domain resources. Frequency domain resources 3 and 5 are sub-frequency domain resources associated with frequency domain resource 4, and their status changes with frequency domain resource 4. Frequency domain resource 2 is a sub-frequency domain resource of frequency domain resource 3 (i.e., frequency domain resource 3 is the parent frequency domain resource of frequency domain resource 2), and its status changes with the state of frequency domain resource 3. Frequency domain resource 6 is a sub-frequency domain resource of frequency domain resource 5 (i.e., frequency domain resource 5 is the parent frequency domain resource of frequency domain resource 6), and its status changes with the state of frequency domain resource 5. Frequency domain resource 7 is a sub-frequency domain resource of frequency domain resource 6 (i.e., frequency domain resource 6 is the parent frequency domain resource of frequency domain resource 7), and its status changes with the state of frequency domain resource 6. Frequency domain resource 1 is a sub-frequency domain resource of frequency domain resource 2 (i.e., frequency domain resource 2 is the parent frequency domain resource of frequency domain resource 1), and its status changes with the state of frequency domain resource 2.

[0075] In some embodiments, when the state of the first type of frequency domain resource in the frequency domain resource set is normal, the state of the frequency domain resources adjacent to or associated with the first type of frequency domain resource is one of the following: normal state, dormant state, or power-saving state.

[0076] In some embodiments, the state of the first type of frequency domain resources does not change with the state of adjacent or associated frequency domain resources; the state of the second type of frequency domain resources changes with the state of associated frequency domain resources.

[0077] For example, when a frequency domain resource is in a normal state, its adjacent / related frequency domain resources are in a dormant state. Then, a second node can allocate resources from the dormant frequency domain resources. For instance, a first node receives a scheduled resource on a normal frequency domain resource that includes a dormant frequency domain resource. Alternatively, the DCI of a normal frequency domain resource A can be used to schedule the PDSCH / PUSCH of a dormant frequency domain resource. Figure 3 is a schematic diagram of frequency domain resource scheduling provided in an embodiment of this application. As shown in Figure 3, a PDSCH is scheduled on the DCI of a normal frequency domain resource 4, which includes both a dormant frequency domain resource 3 and a normal frequency domain resource 4. Since the first node only refrains from blind detection / listening to the PDCCH on the dormant frequency domain resources, scheduling the dormant frequency domain resources does not require a switching time. In other words, the normal and dormant frequency domain resources form an active large BWP, and the frequency domain resources on the active large BWP can be scheduled.

[0078] For example, when a frequency domain resource is in a normal state, its adjacent / associated frequency domain resources are in a power-saving state. Frequency domain resources in the power-saving state can be scheduled on frequency domain resources in the normal state. That is, the DCI received by the first node on frequency domain resources in the normal state can schedule / indicate PDSCH / PUSCH on frequency domain resources in the power-saving state. Alternatively, frequency domain resources in the normal state can be scheduled on frequency domain resources in the power-saving state. That is, the DCI received by the first node on frequency domain resources in the power-saving state can schedule / indicate PDSCH / PUSCH on frequency domain resources in the normal state. Or, PDSCH / PUSCH on both normal and power-saving frequency domain resources can be scheduled. The DCI received by the first node on frequency domain resources in the power-saving state and the scheduled PDSCH / PUSCH must meet the configuration / activation requirements of the frequency domain resources in the power-saving state. Figure 4 is a schematic diagram of another frequency domain resource scheduling provided in an embodiment of this application. As shown in Figure 4, a PDSCH is scheduled on frequency domain resource 2 in a normal state using DCI. This PDSCH includes frequency domain resource 1 in a power-saving state and frequency domain resource 2 in a normal state. A PDSCH is scheduled on frequency domain resource 3 in a power-saving state using DCI. This PDSCH includes frequency domain resource 3 in a power-saving state and frequency domain resource 2 in a normal state. It can be understood that frequency domain resources 1, 2, and 3 form an active large BWP, and frequency domain resources on the active large BWP can be scheduled.

[0079] The first node's DCI reception and PDSCU / PUSCH scheduling for frequency domain resources in power-saving mode need to meet the configuration / activation requirements of frequency domain resources in power-saving mode. For example, the minimum K0(K0) configuration for frequency domain resources in power-saving mode. min If the value of K0 is {0, 2} and the currently effective minimum K0 value is 2, then the DCI transmitted on frequency domain resources in power-saving state should satisfy K0 ≥ 2. Resource scheduling DCIs that include frequency domain resources in power-saving state (transmitted on frequency domain resources in normal state or power-saving state) should also satisfy K0 ≥ 2.

[0080] In some embodiments, in addition to the state change with the associated frequency domain resources, the state of frequency domain resources can be switched according to some other conditions. That is, the state of multiple frequency domain resources is determined according to a first condition, which includes at least one of the following: data scheduling indication, timer, state change of related frequency domain resources, connected discontinuous reception (C-DRX) state of the first node, discontinuous reception / discontinuous transmission state of the cell, and indication signaling.

[0081] Specifically, when the first condition is a data scheduling instruction, for example, a frequency domain resource in power-saving mode switches to normal mode after receiving a data scheduling instruction. For example, a frequency domain resource in dormant mode switches to either power-saving or normal mode after receiving a data scheduling instruction.

[0082] In this configuration, when the first condition is a timer, for example, after the timer expires, the frequency domain resource in the power-saving state switches to a sleep state or an inactive state. For example, after the timer expires, the frequency domain resource in the sleep state switches to an inactive state. For example, after the timer expires, the frequency domain resource in the normal state switches to a power-saving state or a sleep state. When the frequency domain resource switches to the normal state and / or sleep state and / or power-saving state, the timer starts running or is triggered. When the timer is running, if a (new) data schedule is received on the frequency domain resource, the timer is reset. The unit of the timer is a slot or millisecond. The timer can be configured in a set of frequency domain resources. The timer can be configured individually for each frequency domain resource. In some embodiments, the timer running in different states of the frequency domain resource is the same. In some embodiments, the timers running in different states of the frequency domain resource are different. That is, multiple timers can be configured for one frequency domain resource. Each timer corresponds to one state.

[0083] Specifically, if the first condition is a change in the state of a relevant frequency domain resource, and the state of a frequency domain resource related to frequency domain resource A changes, then the state of frequency domain resource A will also change. For example, if the state of frequency domain resource B related to frequency domain resource A switches to a normal state, then the state of frequency domain resource A switches to a power-saving state or a dormant state. Similarly, if the state of frequency domain resource B related to frequency domain resource A switches to a power-saving state, then the state of frequency domain resource A switches to a dormant state or an inactive state. Finally, if the state of frequency domain resource B related to frequency domain resource A switches to a dormant state, then the state of frequency domain resource A switches to an inactive state.

[0084] In some embodiments, when the first condition is the C-DRX state of the first node, the state of the frequency domain resources is related to the C-DRX state of the first node. For example, during C-DRX active time, the activated frequency domain resources are in a normal state; during C-DRX non-active time, the activated frequency domain resources are in a power-saving state or a dormant state. For example, the activated frequency domain resources mentioned above are activated second-type frequency domain resources.

[0085] Wherein, when the first condition is the Discontinuous Reception (DRX) / Discontinuous Transmission (DTX) state of the cell, in some embodiments, the state of the frequency domain resources is related to the state of the Cell DTX / DRX. For example, when in the Cell DTX / DRX active time, the activated frequency domain resources are in a normal state or a power-saving state; when in the Cell DTX / DRX non-active time, the activated frequency domain resources are in a power-saving state or a dormant state. For example, the activated frequency domain resources mentioned above are activated second-type frequency domain resources.

[0086] Wherein, when the first condition is an indication signaling, the indication signaling is used to indicate at least one of the following: one of a plurality of frequency domain resources is designated as a first type of frequency domain resource; switching of the first type of resource among the plurality of frequency domain resources; whether multiple frequency domain resources support simultaneous activation of more than one frequency domain resource among the plurality of frequency domain resources; the state of each frequency domain resource in the frequency domain resource set; the state of the frequency domain resource set. In some embodiments, the indication signaling indicates the state of the frequency domain resource set, and all frequency domain resources in the frequency domain resource set switch to the indicated state. In some embodiments, the indication signaling indicates the state of the frequency domain resource set, and all active frequency domain resources in the frequency domain resource set switch to the indicated state. In some embodiments, the indication signaling indicates the state of each frequency domain resource in the frequency domain resource set, for example, by indicating the state of each frequency domain resource in the frequency domain resource set through a bitmap, and the corresponding frequency domain resource in the frequency domain resource set switches to the indicated state. In some embodiments, the indication signaling indicates a frequency domain resource switch, or indicates a state switch of a frequency domain resource. For example, the indication signaling indicates the index (or identifier) ​​of a frequency domain resource, and the active frequency domain resource within the frequency domain resource group switches to the corresponding frequency domain resource. This can instruct a switch to a first-class frequency domain resource within a set of frequency domain resources (e.g., a frequency domain resource group). The original first-class frequency domain resource is then converted to a second-class frequency domain resource. For example, the instruction signaling can indicate the state of a frequency domain resource: '00' indicates normal state, '01' indicates power-saving state, '10' indicates sleep state, and '11' indicates inactive state. Activated frequency domain resources or first-class frequency domain resources are switched to the corresponding frequency domain resource state according to the instruction signaling. For example, the instruction signaling can indicate the configuration index (or identifier) ​​of a frequency domain resource, instructing a switch to the corresponding configuration.

[0087] The first condition used may differ at different times. For example, when the frequency domain resource is in a normal state, the state switch is determined based on whether the timer has expired and / or signaling indications. When the frequency domain resource is in a power-saving or sleep state, the state switch is determined based on whether data scheduling and / or signaling indications are received. When the frequency domain resource is in an inactive state, the state switch is determined based on the relevant frequency domain resource status and / or signaling indications. For example, when the first set of frequency domain resources is enabled, the switch to the second set of frequency domain resources is determined based on the timer and / or signaling indications. When the second set of frequency domain resources is enabled, the switch to the first set of frequency domain resources is determined based on signaling indications and / or the presence or absence of data scheduling. The second set of frequency domain resources is more power-efficient than the first set. Here, the first and second sets of frequency domain resources are only used to distinguish different frequency domain resources. This can be the frequency domain resource configuration described above.

[0088] In some embodiments, a first condition is determined based on first preset information; the first preset information includes at least one of the following: current frequency domain resource configuration status; C-DRX status of the first node; signaling indication.

[0089] In some embodiments, for each frequency domain resource in the frequency domain resource set, when the frequency domain resource is in a normal state, the frequency domain resource state is determined based on whether the timer has expired and / or signaling indication; when the frequency domain resource is in a power-saving state or a sleep state, the frequency domain resource state is determined based on whether data scheduling and / or signaling indication have been received.

[0090] In some embodiments, at least one first-class frequency domain resource in a set of frequency domain resources is activated.

[0091] In some embodiments, at least one of the multiple frequency domain resources is configured with Virtual Resource Block to Physical Resource Block (VRB-to-PRB) interleaving parameters, or each of the multiple frequency domain resources is configured with VRB-to-PRB interleaving parameters. When a PDSCH or PUSCH is scheduled within an active frequency domain resource, interleaving mapping to a Physical Resource Block (PRB) is performed according to the configured VRB-to-PRB interleaving parameters; and / or when a PDSCH or PUSCH is scheduled within multiple active frequency domain resources, interleaving mapping to a PRB is performed separately within each scheduled active frequency domain resource according to the configured VRB-to-PRB interleaving parameters. No interleaving mapping is performed between multiple active frequency domain resources. In some embodiments, the frequency domain resource group is configured with VRB-to-PRB interleaving parameters. When PDSCH or PUSCH is scheduled in multiple active frequency domain resources, interleaving mapping is performed according to the VRB-to-PRB interleaving parameters configured in the frequency domain resource group. If PDSCH or PUSCH is scheduled in an active frequency domain resource, physical resource blocks are interleaved according to the VRB-to-PRB interleaving parameters configured in that frequency domain resource.

[0092] In some embodiments, when a PDSCH or PUSCH is scheduled within an active frequency domain resource, if interleaving is used, an interleaving mapping PRB is performed according to the interleaving parameters configured in the frequency domain resource. When a PDSCH or PUSCH is scheduled within multiple active frequency domain resources, if interleaving is used, an interleaving mapping PRB is performed separately within each scheduled active frequency domain resource, and then interleaving between frequency domain resources is performed. The interleaving rules between frequency domain resources are predefined.

[0093] In some embodiments, interleaving is enabled only when a PDSCH or PUSCH is scheduled within an active frequency domain resource. That is, interleaving is not enabled when a PDSCH or PUSCH is scheduled within multiple active frequency domain resources.

[0094] In 5G communication systems, time-domain resource configuration and frequency-domain resource configuration are configured separately for each frequency-domain resource. Therefore, when multiple small BWPs are combined into a large BWP, it is necessary to consider how to determine and indicate the time-domain resource configuration and frequency-domain resource configuration.

[0095] A frequency domain resource group / frequency domain resource set can be configured as a large BWP.

[0096] In some embodiments, each downlink frequency domain resource set is configured with at least one of the following: PDSCH configuration parameters, PDSCH time domain resource allocation parameter set, PDSCH frequency domain resource related parameters (unit resource indication granularity, frequency domain resource allocation method, frequency domain resource size, etc.), PRB bundling type (prb-BundlingType), and rate matching related parameters.

[0097] In some embodiments, each uplink frequency domain resource set is configured with at least one of the following: PUSCH configuration parameters, PUSCH time domain resource allocation parameter set, PUSCH frequency domain resource related parameters (unit resource indication granularity, frequency domain resource allocation method, frequency domain resource size, etc.), power control related parameters, PUCCH configuration parameters, and codebook related parameters.

[0098] When more than one frequency domain resource is active in a frequency domain resource set, the parameters configured in the frequency domain resource set take effect. That is, data scheduling can be performed according to the configuration in the frequency domain resource set. If a parameter is configured in the frequency domain resource set, the configured parameters in the frequency domain resource set take effect; if certain parameters are not configured in the frequency domain resource set, the parameter configuration on the first type of frequency domain resource or the frequency domain resource receiving DCI is used. In other words, when multiple frequency domain resources are active, the configuration parameters in the frequency domain resource set will replace the corresponding configuration parameters on the first type of frequency domain resource or the frequency domain resource receiving DCI.

[0099] In some embodiments, when there are more than one active frequency domain resource in a frequency domain resource set, and when data scheduling needs to span multiple frequency domain resources, the time domain resource configuration is indicated according to the time domain configuration-related parameters on the frequency domain resources receiving the DCI.

[0100] The advantage of configuring multiple related frequency domain resources is that when data packets are large, resources from multiple frequency domain resources can be directly scheduled, speeding up data packet transmission. Frequency domain resources also consume less energy outside of normal operation.

[0101] In one embodiment, frequency domain resource configuration is used to configure an uplink frequency domain resource set and / or a downlink frequency domain resource set. The uplink frequency domain resource set is activated or deactivated together with the downlink frequency domain resource set; and / or at least one first-type frequency domain resource in the uplink frequency domain resource set has the same center frequency as at least one first-type frequency domain resource in the downlink frequency domain resource set.

[0102] In some embodiments, the configuration and / or status of uplink and downlink frequency domain resources must remain the same. That is, both uplink and downlink will have frequency domain resource groups configured, and the status of each frequency domain resource within them must remain the same.

[0103] In some embodiments, each frequency domain resource in the uplink frequency domain resource set is associated with one frequency domain resource in a downlink frequency domain resource set; or each frequency domain resource in the downlink frequency domain resource set is associated with one uplink frequency domain resource. The center frequency of the uplink first-type frequency domain resource must be the same as the center frequency of its associated (same identifier) ​​downlink first-type frequency domain resource. The center frequency of other second-type frequency domain resources is not required. Figure 5 is a schematic diagram of the uplink and downlink frequency domain resource association relationship provided in an embodiment of this application. As shown in Figure 5, both the uplink frequency domain resource set and the downlink frequency domain resource set include three frequency domain resources, wherein the center frequency of downlink frequency domain resource 1 is the same as that of uplink frequency domain resource 1.

[0104] When downlink and uplink frequency domain resources are in one-to-one correspondence, for ACK-NACK, in some embodiments, when a downlink schedule is scheduled across multiple frequency domain resources, its ACK-NACK is fed back on the uplink first-type frequency domain resources; when a downlink schedule is transmitted only on one frequency domain resource, its ACK-NACK is fed back on its corresponding downlink frequency domain resource. In some embodiments, all downlink data schedule ACK-NACKs are transmitted on the uplink first-type frequency domain resources. For CSI reports, in some embodiments, CSI reports are transmitted only on the uplink first-type frequency domain resources; in other embodiments, CSI reports are transmitted on the corresponding uplink frequency domain resources.

[0105] In some embodiments, uplink and downlink traffic volumes differ, with downlink traffic sometimes being higher and uplink traffic sometimes being higher. Therefore, the activation and / or status of uplink and downlink frequency domain resources may not match.

[0106] When downlink traffic is high and uplink traffic is low, a downlink frequency domain resource set is associated with an uplink frequency domain resource. The center frequency of the uplink frequency domain resource is the same as the center frequency of the first type of frequency domain resource in the downlink frequency domain resource set. Figure 6 is a schematic diagram of another uplink and downlink frequency domain resource association provided by an embodiment of this application. As shown in Figure 6, the uplink frequency domain resource set includes one uplink frequency domain resource, and the downlink frequency domain resource set includes three frequency domain resources. The center frequency of downlink frequency domain resource 1 is the same as that of uplink frequency domain resource 1.

[0107] Downlink traffic is low, while uplink traffic is high; one downlink frequency domain resource is associated with one set of uplink frequency domain resources. In some embodiments, uplink and downlink traffic volumes change over time. The configuration and / or status of uplink and downlink frequency domain resources need to change as service demands evolve.

[0108] In some embodiments, the first signaling indicates whether the second type of frequency domain resources in the uplink or downlink frequency domain resource set are activated or used. Whether the second type of uplink and downlink frequency domain resources are used can be indicated to the first node via signaling from the second node. For example, when there is a lot of uplink traffic and a little downlink traffic, it can be indicated that the downlink second type of frequency domain resources are not used / deactivated, while the uplink second type of frequency domain resources can be used. When there is little uplink traffic and a lot downlink traffic, it can be indicated that the uplink second type of frequency domain resources are not used / deactivated, while the downlink second type of frequency domain resources can be used / activated. When there is a lot of both uplink and downlink traffic, it can be indicated that the downlink second type of frequency domain resources can be used / activated, and the uplink second type of frequency domain resources can be used / activated. When there is little uplink and downlink traffic, it can be indicated that the downlink second type of frequency domain resources are not used / disabled / not activated, and the uplink second type of frequency domain resources are not used / not activated. It should be noted that "use / enable" here refers to whether the state of the frequency domain resources can be changed, or whether scheduling is possible on the frequency domain resources. Only by using / enabling can the status of frequency domain resources be further determined.

[0109] In some embodiments, the frequency domain resource configuration configures a first frequency domain resource, which is divided into N second frequency domain resources according to a first rule. The first rule is predefined or indicated by predetermined signaling; and / or the first rule is determined according to the configuration of the control resource set (CORESET).

[0110] The second node configures a first frequency domain resource configuration for the first node. This first frequency domain resource configuration can be divided into N second frequency domain resource configurations according to a first rule. The first rule is at least one of the following: a predefined frequency domain resource unit, a CORESET configuration, or a signaling indication. For example, 0 RBs / Resource Block Groups (RBGs). Then, each 0 RBs / RBGs constitutes one second frequency domain resource. If a node has fewer than 0 RBs / RBGs, then all remaining RBs / RBGs constitute one second frequency domain resource. 0 can be predefined or indicated by signaling (e.g., RRC signaling). Figure 7 is a schematic diagram of frequency domain resource partitioning provided by an embodiment of this application. As shown in Figure 7, the first frequency domain resource includes 5 second frequency domain resources. Second frequency domain resources 1-4 each include 0 RBs, and the remaining RBs form second frequency domain resource 5.

[0111] The first rule is the configuration of CORESETs. For example, different second frequency domain resources are configured according to the frequency domain location of the CORESET. Each second frequency domain resource contains at least one CORESET. Figure 8 is a schematic diagram of another frequency domain resource partitioning provided by an embodiment of this application. As shown in Figure 8, the first frequency domain resource includes four second frequency domain resources, and each second frequency domain resource includes at least one CORESET.

[0112] The first rule is signaling indication. For example, RRC signaling / DCI signaling indicates the frequency domain location of each second frequency domain resource configuration.

[0113] In some embodiments, if after partitioning the second frequency domain resources, there exists a CORESET or other parameter configuration that spans multiple second frequency domain resources, then the CORESET or other parameter is only effective when all the multiple second frequency domain resources spanned are in normal or power-saving state.

[0114] In some embodiments, configuration information on second frequency domain resources in normal, power-saving, dormant, or active states is valid. For example, if a CSI-RS configuration spans multiple second frequency domain resources, the first node only receives CSI-RS on active second frequency domain resources. For example, the UE only performs blind detection / listening DCI on active second frequency domain resources (excluding dormant states). For example, only active second frequency domain resources can be scheduled.

[0115] The following is an illustration of a specific frequency domain resource set configuration:

[0116] Configure a frequency domain resource group, which includes multiple frequency domain resources that are interconnected. For example, frequency domain resource 1 is associated with frequency domain resource 2, frequency domain resource 2 is associated with frequency domain resource 1 and frequency domain resource 3, frequency domain resource 3 is associated with frequency domain resource 2 and frequency domain resource 4, and so on. Configure the initially activated frequency domain resource via RRC, or activate a predefined frequency domain resource. For example, if RRC configures frequency domain resource 2 as the initially activated frequency domain resource, then frequency domain resource 2 is in a normal state, its associated frequency domain resources 1 and 3 are in a dormant state, and frequency domain resource 4 is in an inactive state. In some embodiments, configuring the initially activated frequency domain resource via RRC, or activating a predefined frequency domain resource, cannot switch it to a dormant, inactive, or power-saving state. Frequency domain resource 2 can receive DCI, and DCI can schedule resources on frequency domain resources 1, 2, and 3. If DCI schedules on frequency domain resource 1 or frequency domain resource 3, the corresponding frequency domain resource switches to a normal state. For example, when frequency domain resource 3 switches to the normal state, a timer on frequency domain resource 3 is triggered, and its associated frequency domain resource 4 switches to the sleep state. If there is no data scheduling on frequency domain resource 3, it switches to the sleep state after the timer expires, and its associated frequency domain resource 4 switches to the inactive state. In this way, adaptive frequency domain resource state switching can be achieved.

[0117] This application also provides frequency domain resource configuration / state switching based on artificial intelligence (AI). The first node and / or the second node use AI models to configure frequency domain resources or adaptively adjust the state of frequency domain resources.

[0118] The second-node model trains / uses the AI ​​model based on the first information, i.e., it uses the first information as input to the AI ​​model. The first information includes at least one of the following: CSI report, channel state information, Quality of Service (QoS) information, packet size, service-related information, frequency domain resource configuration information, PDCCH monitoring search space set and control resource set configuration information, PDSCH scheduling information, reference signal configuration information, and channel state information measurement configuration information. The CSI report includes at least one of the following: RI, PMI, CQI, Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), and LI. The service QoS information includes at least one of the following: QoS level, latency requirements, reliability indicators, priority information, etc. The service-related information includes at least one of the following: arrival time, period, and service jitter information, etc. The frequency domain resource configuration information includes at least one of the following: frequency domain resource size (e.g., BWP size) / available frequency domain resource size / available frequency domain resource size for scheduling, number of frequency domain resources, and modulation and coding scheme (MCS) related information.

[0119] The AI ​​model outputs second information based on the first information. The second information includes at least one of the following: frequency domain resource configuration information and frequency domain resource activation / configuration information. The frequency domain resource configuration information includes: frequency domain resource group configuration information, the number of frequency domain resources within the frequency domain resource group, the frequency domain resource status, the frequency domain resource size (e.g., BWP size) / available frequency domain resource size / schedulable frequency domain resource size, the number of frequency domain resources, and MCS-related information. The frequency domain resource activation / configuration information includes: the recommended activated frequency domain resources, the recommended configured frequency domain resource size, the recommended frequency domain resource status, the number of frequency domain resources in the recommended configured frequency domain resource group, the recommended activated frequency domain resource group, the recommended configured frequency domain resource number, the recommended configured / used MCS, the recommended configured / used sub-carrier space (SCS), the recommended configured time domain resource configuration information, the recommended configured frequency domain resource configuration information, and the recommended triggered frequency domain resource status. For example, the AI ​​model outputs the recommended activated frequency domain resources based on CSI information. For example, the AI ​​model outputs the recommended triggered frequency domain resource status based on CSI information. For example: The AI ​​model outputs suggested frequency domain resources to be activated based on CSI information and service-related information. For example: The AI ​​model outputs suggested frequency domain activation configurations / activations based on service packet size and / or service QoS information, or suggests the configuration / use of MCS, and / or suggests the triggering of frequency domain resource status. For example: The AI ​​model outputs suggested activated frequency domain resources and / or suggested triggering frequency domain resource status based on CSI information, service QoS information, and frequency resource configuration information.

[0120] The second node configures frequency domain resources based on the second information. The second node instructs frequency domain resource switching based on the second information. The second node indicates the frequency domain resource status based on the second information. The second node configures frequency domain resource groups based on the second information. The second node instructs frequency domain resource group activation / deactivation based on the second information. The second node instructs switching of the first type of frequency domain resources within the frequency domain resource group based on the second information.

[0121] The first node-side AI model is the same as the second node-side AI model, but outputs second information based on the first information. The first information is the same as above, and additionally may include at least one of the following: activated frequency domain resource configuration, activated frequency domain resource status. In some embodiments, the first node sends a third signaling to the second node based on the output second information. The third signaling includes the second information.

[0122] The AI ​​models on both the second and first nodes form a bilateral model. The AI ​​model can be trained on the second node and sent to the first node, or trained on the first node and sent to the second node. The second and first nodes adaptively switch frequency domain resources or frequency domain resource states based on the AI ​​model. Since the second and first nodes use the same AI model, their output second information should be identical. However, to ensure reliability, synchronization / calibration is still required. Synchronization / calibration can be achieved by the first node sending a fourth signaling message to the second node at a predefined time, or by the second node sending a fourth signaling message to the first node at a predefined time. The predefined time is determined by the time parameters (e.g., period, offset, etc.) configured by the second node for the first node. The fourth signaling message includes the second information output by the AI ​​model. The receiving end compares the received fourth signaling message (i.e., the information output by its own AI model) to determine whether to continue using the AI ​​model or stop using it. If the AI ​​model is to be stopped, the receiving end can send a fifth signaling message to either the first or second node to inform them that the AI ​​model has been discontinued.
