The term "base station" is not limited to specific technical terms. It should be noted that this application embodiment only uses a base station in an NR system as an example for description and does not limit the specific type of base station.

[0112] To better understand the technical solution of this application, the following describes the scheduling-based BWP handover.

[0113] A currently connected terminal (UE) can be configured with one or more BWPs in a serving cell. BWP handover is used to simultaneously activate an inactive BWP and deactivate an active BWP. BWP handover methods include: control using the Physical Downlink Control Channel (PDCCH), control using a BWP deactivation timer (bwp-inactivityTimer), control using Radio Resource Control (RRC) signaling, or control by the Media Access Control (MAC) entity itself when performing random access procedures or detecting consecutive Listen Before Talk (LBT) failures on a Special Cell (SpCell).

[0114] For BWP handover controlled by bwp-InactivityTimer, one bwp-InactivityTimer is configured for each serving cell, and one active BWP is associated with one bwp-InactivityTimer.

[0115] If the currently active BWP is not the default BWP (as indicated by defaultDownlinkBWP-Id), or if the currently active BWP is not the initial BWP (as indicated by defaultDownlinkBWP-Id when defaultDownlinkBWP-Id is not configured), and if it is not a dormant BWP (as associated with dormantBWP-Id) when dormantBWP-Id is configured, and there is a schedule, including the following:

[0116] The PDCCH indicating downlink allocation or uplink authorization is received on the BWP with scrambled Cell Radio Network Temporary Identity (C-RNTI) or Configured Scheduling Radio Network Temporary Identity (CS-RNTI);

[0117] Alternatively, it may receive an indication to allocate a downlink PDCCH scrambled with either the Group Radio Network Temporary Identity (G-RNTI) configured for multicast or the Group Configured Scheduling Radio Network Temporary Identity (G-CS-RNTI);

[0118] Or it received a PDCCH indicating downlink allocation or uplink authorization for an activated BWP with C-RNTI or CS-RNTI scrambling;

[0119] Alternatively, a Media Access Control Protocol Data Unit (MAC PDU) was transmitted on the configured grant and no LBT failure indication was received from the underlying layer;

[0120] Alternatively, a unicast-related MAC PDU or a multicast service (MBS)-related MAC PDU may be received on the downlink allocation.

[0121] If there is no running random access procedure in the current serving cell, or if the running random access procedure successfully completes after receiving the C-RNTI scrambled PDCCH, then the BWP-related bwp-InactivityTimer will be started or restarted.

[0122] For non-redcap UEs, the initial BWP is the BWP configured with the initial downlink BWP. For redcap UEs, the initial BWP is either the initial downlink BWP-RedCap (if configured) or the initial downlink BWP (if initial downlink BWP-RedCap is not configured).

[0123] When the bwp-InactivityTimer associated with the active BWP expires, if a default BWP is configured, the UE will perform a BWP handover and switch to the default BWP; otherwise, the UE will switch to the initial BWP.

[0124] When the UE receives a PDCCH for BWP handover, and the active BWP indicated by the PDCCH is not the default BWP (the BWP indicated by defaultDownlinkBWP-Id) or not the initial BWP (when defaultDownlinkBWP-Id is not configured), and is not the dormitory BWP when dormitoryBWP-Id is configured, then the UE starts or restarts the bwp-InactivityTimer associated with that BWP.

[0125] When a UE performs a Random Access Channel (RACH) procedure in a serving cell, after selecting a carrier, the UE stops the bwp-inactivityTimer of the active BWP associated with that serving cell for that carrier. If the cell is a secondary cell (SCell), the UE also stops the bwp-inactivityTimer of the active BWP of the SCell.

[0126] When the network side releases the configuration of bwp-InactivityTimer in the Radio Resource Control (RRC) signaling, the UE must stop the bwp-InactivityTimer of the active BWP in the serving cell.

[0127] To better understand the technical solution of this application, the following describes BWP handover based on random access.

[0128] A currently connected UE can be configured with one or more Backdoor Window (BWP) within a serving cell, but only one BWP can be active. When a UE initiates random access, it needs to check whether the currently active uplink BWP has RACH resources configured. If not, the UE needs to switch to the initial uplink BWP.

[0129] When a connected UE initiates random access, the bwp-InactivityTimer related to the active BWP of the current serving cell needs to be stopped. If the current serving cell is an SCell, the bwp-InactivityTimer related to the active BWP of the SpCell also needs to be stopped.

Thus, the terminal can reasonably perform relevant operations (such as switching, activation, etc.) on the uplink frequency domain resource based on the first and second conditions when initiating random access, and can also improve the performance of uplink frequency domain resource scheduling and switching during random access.

[0170] Optionally, the terminal type can be an Internet of Things (IoT) terminal, an Ambient Internet of Things (A-IoT) terminal, a Reduced Capability (RedCap) terminal, a Non-Terrestrial Network (NTN) terminal, a Very Small Aperture Terminal (VSAT) terminal, an A-IoT+RedCap terminal, an A-IoT+NTN terminal, an IoT+NTN terminal, etc.

[0171] It should be noted that an A-IoT+RedCap terminal indicates that the terminal can support both A-IoT and RedCap features simultaneously, such as a RedCap terminal equipped with an A-IoT module. A-IoT+NTN terminals, IoT+NTN terminals, etc. are similar, and will not be elaborated further here.

[0173] Optionally, the terminal's capabilities can include whether the terminal supports multiple active uplink frequency domain resources, the number of receive antennas or transmit antennas supported by the terminal, and the channel bandwidth or BWP bandwidth supported by the terminal.

[0175] It should be noted that the terminal's terminal energy consumption level can also be understood or replaced as the terminal's terminal energy consumption status.

[0176] For example, the terminal energy consumption level indicates the level of energy consumption of the terminal when performing a service. If the terminal is performing an Extended Reality (XR) service, it is a high power consumption service.

[0184] In this embodiment, the target uplink frequency domain resource can be an uplink frequency domain resource that is temporarily activated during the random access process, and the terminal deactivates the target uplink frequency domain resource after completing the random access.

[0185] It should be noted that for multi-active uplink frequency domain resources, it is not necessarily only the initial uplink frequency domain resource that is configured with RO, thereby optimizing uplink transmission during random access. Taking uplink frequency domain resources as an example of uplink BWP, for multi-active UL BWP, it is not necessarily only the initial UL BWP that is configured with RO.

[0186] In some embodiments, the terminal preferentially switches to a non-initial target uplink frequency domain resource that is configured with random access resources. In other words, the target uplink frequency domain resource is a non-initial uplink frequency domain resource configured with random access resources.

[0187] In this embodiment, the terminal selects other non-initial uplink frequency domain resources configured with RO (such as the target uplink frequency domain resource), which helps to balance the random access load (RACH load) among different uplink frequency domain resources, so that the terminal does not have to return to the initial uplink frequency domain resource to initiate random access (RACH).

[0195] In this embodiment, if the third condition is met, the terminal switches to the first target downlink frequency domain resource when initiating random access; and / or, if the fourth condition is met, the terminal activates the first target downlink frequency domain resource when initiating random access. Thus, the terminal can reasonably perform relevant operations (such as switching, activation, etc.) on the downlink frequency domain resource based on the third and fourth conditions when initiating random access, and can also improve the performance of downlink frequency domain resource scheduling and switching during random access.

[0196] In some embodiments, the third condition is agreed upon by a protocol, or the third condition is configured by a network-side device.

[0199] In some embodiments, where the second operation includes activating the first target downlink frequency domain resource, the wireless communication method 200 further includes:

[0200] After completing random access, the terminal activates the first target downlink frequency domain resource.

[0201] In this embodiment, the first target downlink frequency domain resource can be a downlink frequency domain resource that is temporarily activated during the random access process. The terminal deactivates the first target downlink frequency domain resource after completing the random access.

[0202] It should be noted that for multiple activated downlink frequency domain resources, it is not necessarily only the initial downlink frequency domain resources that are configured with random access response resources, thereby optimizing downlink transmission during the random access process.

[0203] In some embodiments, the terminal preferentially switches to a non-initial downlink frequency domain resource (such as a first target downlink frequency domain resource) that is configured with random access response resources. In other words, the first target downlink frequency domain resource is a non-initial downlink frequency domain resource that is configured with random access response resources.

[0204] In this embodiment, the terminal selects other non-initial downlink frequency domain resources (such as the first target downlink frequency domain resource) that are configured with random access response resources. This helps to balance the random access load (RACHload) among different downlink frequency domain resources, so that the terminal does not have to return to the initial downlink frequency domain resource to perform random access response.

[0209] The terminal does not support multiple activations of downlink frequency domain resources; the currently activated downlink frequency domain resource does not enable multiple activations of downlink frequency domain resources; the second target downlink frequency domain resource does not enable multiple activations of downlink frequency domain resources; the currently activated downlink frequency domain resource and the second target downlink frequency domain resource do not enable multiple activations of downlink frequency domain resources; the currently activated downlink frequency domain resource and the second target downlink frequency domain resource overlap in the time domain or frequency domain; the serving cell is SpCell, and at least one activated downlink frequency domain resource does not contain a downlink frequency domain resource with the same identifier as the first uplink frequency domain resource; at least one activated downlink frequency domain resource does not contain a downlink frequency domain resource with the same identifier as the first uplink frequency domain resource; the deactivation timer for at least one activated downlink frequency domain resource is not running;

[0212] In this embodiment, if the fifth condition is met, the terminal switches to the second target downlink frequency domain resource when initiating random access; and / or, if the sixth condition is met, the terminal activates the second target downlink frequency domain resource when initiating random access. Thus, the terminal can reasonably perform relevant operations (such as switching, activation, etc.) on the downlink frequency domain resource based on the fifth and sixth conditions when initiating random access, and can also improve the performance of downlink frequency domain resource scheduling and switching during random access.

[0213] In some embodiments, the fifth condition is agreed upon by a protocol, or the fifth condition is configured by a network-side device.

[0214] In some embodiments, the sixth condition is agreed upon by a protocol, or the sixth condition is configured by a network-side device.

[0215] In some embodiments, the identifier of the second target downlink frequency domain resource is the same as the identifier of the first uplink frequency domain resource. Taking a BWP as an example, the second target downlink frequency domain resource can be a BWP.

[0216] In some embodiments, the second target downlink frequency domain resource includes a third target downlink frequency domain resource, the identifier of which is the same as the identifier of the first uplink frequency domain resource. Optionally, the second target downlink frequency domain resource may include at least two downlink frequency domain resources, wherein the third target downlink frequency domain resource may be one of the at least two downlink frequency domain resources. Taking a BWP as an example, the second target downlink frequency domain resource may be an aggregation of multiple discrete BWPs.

[0220] In this embodiment, the terminal deactivates K downlink frequency domain resources, wherein the deactivation timers for the K downlink frequency domain resources are not running, thereby reducing the terminal power consumption caused by activating downlink frequency domain resources.

[0221] It should be noted that the deactivation timer for the activated downlink frequency domain resource is running, indicating that the activated downlink frequency domain resource may be continuously receiving scheduling based on other services. Therefore, deactivation may not be performed on it.

[0222] For example, taking the following frequency domain resource as a BWP, perform deactivation operations on K active DL BWPs where the deactivation timer (bwp-inactivityTimer) is not running.

[0261] Optionally, the terminal type can be IoT terminal, A-IoT terminal, RedCap terminal, NTN terminal, VSAT terminal, A-IoT+RedCap terminal, A-IoT+NTN terminal, IoT+NTN terminal, etc.

[0262] It should be noted that an A-IoT+RedCap terminal indicates that the terminal can support both A-IoT and RedCap features simultaneously, such as a RedCap terminal equipped with an A-IoT module. A-IoT+NTN terminals, IoT+NTN terminals, etc. are similar, and will not be elaborated further here.

[0263] Optionally, the list of terminal types may include, but is not limited to, at least one of the following: IoT terminal, A-IoT terminal, RedCap terminal, NTN terminal, VSAT terminal.

[0264] Optionally, the terminal's capabilities can include whether the terminal supports multiple active uplink frequency domain resources, the number of receive antennas or transmit antennas supported by the terminal, and the channel bandwidth or BWP bandwidth supported by the terminal.

[0271] Figure 4 This is a schematic flowchart of a wireless communication method 400 according to an embodiment of this application, such as... Figure 4 As shown, the wireless communication method 400 may include at least some of the following:

[0272] S410, the terminal performs the fourth operation when initiating random access; or, the terminal performs the fifth operation when initiating random access.

[0273] The fourth operation includes one of the following: stopping the deactivation timer of some or all downlink frequency domain resources that are active, or not stopping the deactivation timer of some or all downlink frequency domain resources that are active.

[0274] The fifth operation includes performing a random access procedure using the activated first downlink frequency domain resources of the first cell and the activated first uplink frequency domain resources of the second cell, wherein random access resources are configured on the first uplink frequency domain resources.

[0275] It should be understood that Figure 4 The steps or operations of the wireless communication method 400 are illustrated, but these steps or operations are merely examples, and other operations may be performed in this application. Figure 4 Variations of various operations within it.

[0276] In this embodiment, the terminal can be in an RRC connected state. Of course, the terminal can also be in other RRC states, and this application is not limited to this.

[0277] It should be noted that when a terminal initiates random access, in order not to affect the reception of the Random Access Response (RAR) or subsequent scheduling, the running deactivation timer needs to be stopped. When the network side is configured with multiple active downlink frequency domain resources, or the terminal supports multiple active downlink frequency domain resources, some active downlink frequency domain resources need to remain active, while other active downlink frequency domain resources do not necessarily need to remain active (e.g., downlink frequency domain resources that the network side does not send RARs to), then it is necessary to stop some or all of the running deactivation timers.

[0278] In this embodiment, when initiating random access, the terminal may either deactivate the deactivation timers for some or all of the activated downlink frequency domain resources, or not deactivate them. This allows for the efficient use of downlink frequency domain resources and improves the performance of downlink frequency domain resource scheduling and handover during random access. Alternatively, when initiating random access, the terminal may use the activated first downlink frequency domain resources of the first cell and the activated first uplink frequency domain resources of the second cell to perform the random access procedure. This improves random access performance and also enhances the performance of uplink and downlink frequency domain resource scheduling and handover during random access.

[0279] The deactivation timer described in this application embodiment can also be called an inactive timer, and this application does not limit it to that.

[0280] The frequency domain resources described in the embodiments of this application can be equivalent to or replaced with BWP or other similar descriptions such as small bandwidth or micro bandwidth. For example, uplink frequency domain resources can be equivalent to or replaced with uplink BWP, and downlink frequency domain resources can be equivalent to or replaced with downlink BWP. This application does not limit this.

[0281] In some embodiments, the first cell and the second cell may be the same or different, and this application embodiment does not limit this.

[0282] In some embodiments, during S410 described above, the terminal performs a fourth operation when initiating random access, including:

[0283] The terminal executes the fourth operation based on the running status of the deactivation timer for partially or fully activated downlink frequency domain resources of the serving cell; or,

[0284] If the serving cell is a secondary cell, the terminal performs the fourth operation based on the running status of the deactivation timer of the partially or fully activated downlink frequency domain resources of the SpCell.

[0285] In some embodiments, the terminal performs the fourth operation based on the running status of the deactivation timer for some or all of the activated downlink frequency domain resources of the serving cell, including at least one of the following:

[0286] If all active downlink frequency domain resources of the serving cell are running deactivation timers, the terminal stops all active downlink frequency domain resources of the serving cell from running deactivation timers.

[0287] If the deactivation timers for all active downlink frequency domain resources of the serving cell are running, the terminal stops the deactivation timers for the active target downlink frequency domain resources of the serving cell.

[0288] If the deactivation timer for at least one active downlink frequency domain resource of the serving cell is running, the terminal stops the deactivation timers for all active downlink frequency domain resources of the serving cell.

[0289] If the deactivation timer for at least one active downlink frequency domain resource of the serving cell is not running, the terminal does not stop the deactivation timers for all active downlink frequency domain resources of the serving cell.

[0290] If the deactivation timer for at least one active downlink frequency domain resource of the serving cell is running, the terminal stops the deactivation timer for the active target downlink frequency domain resource of the serving cell.

[0291] If the deactivation timer for at least one active downlink frequency domain resource of the serving cell does not run, the terminal does not stop the deactivation timer for the active target downlink frequency domain resource of the serving cell.

[0292] If the serving cell has only one active downlink frequency domain resource, and the deactivation timer of the active downlink frequency domain resource is running, the terminal stops the deactivation timer of the active downlink frequency domain resource.

[0293] In this embodiment, the terminal can determine whether to stop the deactivation timer of the activated downlink frequency domain resources based on the running status of the deactivation timer of the activated downlink frequency domain resources in the serving cell, thereby enabling more flexible control over the deactivation timer of the activated downlink frequency domain resources in the serving cell.

[0294] In some embodiments, the terminal performs the fourth operation based on the running status of the deactivation timer for some or all of the activated downlink frequency domain resources of SpCell, including at least one of the following:

[0295] If all active downlink frequency domain resources of the SpCell are running deactivation timers, the terminal stops all active downlink frequency domain resources of the SpCell from running.

[0296] If all the deactivation timers for the active downlink frequency domain resources of the SpCell are running, the terminal stops the deactivation timer for the active target downlink frequency domain resource of the SpCell.

[0297] If the deactivation timer of at least one active downlink frequency domain resource of the SpCell is running, the terminal stops the deactivation timers of all active downlink frequency domain resources of the SpCell.

[0298] If the deactivation timer of at least one active downlink frequency domain resource of the SpCell does not run, the terminal does not stop the deactivation timers of all active downlink frequency domain resources of the SpCell.

[0299] If the deactivation timer of at least one active downlink frequency domain resource of the SpCell is running, the terminal stops the deactivation timer of the active target downlink frequency domain resource of the SpCell;

[0300] If the deactivation timer of at least one active downlink frequency domain resource of the SpCell does not run, the terminal does not stop the deactivation timer of the active target downlink frequency domain resource of the SpCell;

[0301] If the SpCell has only one active downlink frequency domain resource, and the deactivation timer of the active downlink frequency domain resource is running, the terminal stops the deactivation timer of the active downlink frequency domain resource.

[0302] In this embodiment, the terminal can determine whether to stop the deactivation timer of the active downlink frequency domain resource based on the running status of the deactivation timer of the active downlink frequency domain resource in the SpCell, thereby enabling more flexible control over the deactivation timer of the active downlink frequency domain resource in the SpCell.

[0303] In some embodiments, the target downlink frequency domain resource satisfies at least one of the following:

[0306] If the serving cell is a secondary cell, the SpCell includes at least two active downlink frequency domain resources, and the at least two active downlink frequency domain resources include the first downlink frequency domain resource. The terminal uses the first downlink frequency domain resource and the first uplink frequency domain resource to perform a random access procedure.

[0307] If the serving cell is a secondary cell, and the SpCell only includes the activated first downlink frequency domain resources, the terminal uses the first downlink frequency domain resources and the first uplink frequency domain resources to perform a random access procedure;

[0308] If the serving cell is a secondary cell, and the SpCell includes an inactive first downlink frequency domain resource, the terminal activates the first downlink frequency domain resource, and the terminal uses the first downlink frequency domain resource and the first uplink frequency domain resource to perform a random access procedure.

[0309] In this embodiment, the first cell is SpCell and the second cell is the serving cell. When the terminal initiates random access, it uses the first downlink frequency domain resources activated by SpCell and the first uplink frequency domain resources activated by the serving cell to perform the random access process, thereby improving the performance of random access and the performance of uplink and downlink frequency domain resource scheduling and handover during random access.

[0310] In some embodiments, the association between the first downlink frequency domain resource and the first uplink frequency domain resource is indicated by the network side. Therefore, the terminal can obtain the association between the first downlink frequency domain resource and the first uplink frequency domain resource based on the network side indication.

[0315] The main idea of ​​Example 1 is as follows: 1. Define a set of features related to BWP so that the network side does not need to allocate a separate BWP for each potential new UE type and UE capability in the future; 2. When the network side configures a multi-active BWP (or configures a multi-active UL BWP and / or a multi-active DL BWP), or the terminal supports a multi-active BWP (or supports a multi-active UL BWP and / or a multi-active DL BWP), the terminal will change some BWP switching operations into BWP activation operations. For the currently active downlink BWP, whether to perform a deactivation operation depends on whether the deactivation timer (bwp-inactivityTimer) is running.

[0382] In some implementations, if the serving cell is SpCell and none of the at least one active downlink BWP has the same BWP identifier (bwp-ID) as the first uplink BWP, the terminal activates a second target downlink BWP when initiating random access, wherein the bwp-ID of the second target downlink BWP is the same as the bwp-ID of the first uplink BWP. For example, if the bwp-ID of the currently active downlink BWP is 2 and the bwp-ID of the first uplink BWP is 3, then the terminal activates the downlink BWP with bwp-ID = 3 (i.e., the second target downlink BWP is the downlink BWP with bwp-ID = 3). Optionally, the bwp-inactivityTimer of the at least one active downlink BWP is running.

Optionally, deactivation operations are performed on the K active downlink BWPs where the bwp-inactivityTimer is not running. Optionally, after the random access procedure is completed, the terminal performs a deactivation operation on the second target downlink BWP.

[0383] In some implementations, if the serving cell is SpCell and none of the at least one active downlink BWP has the same BWP identifier (bwp-ID) as the first uplink BWP, the terminal switches to the second target downlink BWP, where the bwp-ID of the second target downlink BWP is the same as the bwp-ID of the first uplink BWP. Optionally, the bwp-inactivityTimer of the at least one active downlink BWP is not running.

Optionally, the terminal does not support multi-active downlink BWPs, or the terminal does not support multi-active BWPs. Optionally, a deactivation operation is performed on the K active downlink BWPs whose bwp-inactivityTimer is not running.

[0384] In some implementations, if none of the at least one active downlink BWPs has the same bwp-ID as the first uplink BWP, the terminal activates a second target downlink BWP when initiating random access, wherein the bwp-ID of the second target downlink BWP is the same as the bwp-ID of the first uplink BWP. For example, if the bwp-ID of the currently active downlink BWP is 2 and the bwp-ID of the first uplink BWP is 3, then the terminal activates the downlink BWP with bwp-ID = 3 (i.e., the second target downlink BWP is the downlink BWP with bwp-ID = 3). Optionally, the bwp-inactivityTimer of the at least one active downlink BWP is running. Optionally, the first configuration information indicates that the second target downlink BWP does not support multi-active downlink BWPs, or the first configuration information indicates that the second target downlink BWP does not support multi-active BWPs.

Optionally, deactivation operations are performed on the K active downlink BWPs whose bwp-inactivityTimer is not running. Optionally, after the random access procedure is completed, the terminal performs deactivation operations on the second target downlink BWP.

[0385] In some implementations, if none of the at least one active downlink BWPs has the same BWP identifier (bwp-ID) as the first uplink BWP, the terminal switches to a second target downlink BWP, wherein the bwp-ID of the second target downlink BWP is the same as the bwp-ID of the first uplink BWP. Optionally, the bwp-inactivityTimer of the at least one active downlink BWP is not running. Optionally, the first configuration information indicates that the second target downlink BWP does not support multi-active downlink BWPs, or the first configuration information indicates that the second target downlink BWP does not support multi-active BWPs. Optionally, the terminal does not support multi-active downlink BWPs, or the terminal does not support multi-active BWPs. Optionally, a deactivation operation is performed on the K active downlink BWPs whose bwp-inactivityTimer is not running.

[0386] Example 2, taking frequency domain resources as BWP as an example. Specifically, Example 2 uses the following scheme as an example: when the terminal initiates random access, the bwp-inactivityTimer is used to process the running active downlink BWP (active DL BWP).

[0387] The main idea of ​​this embodiment is that when a terminal initiates random access, in order not to affect RAR reception or subsequent scheduling, it needs to stop the running bwp-inactivityTimer. When the network side is configured with multi-active BWP (or configured with multi-active UL BWP and / or multi-active DL BWP), or the terminal supports multi-active BWP (or supports multi-active UL BWP and / or multi-active DL BWP), some active downlink BWPs need to remain active, while other active downlink BWPs do not necessarily need to remain active (e.g., DLBWPs that do not transmit RAR on the network side), then it is not necessary to stop the running bwp-inactivityTimer of the serving cell.

[0388] Optionally, such as Figure 6 As shown, Embodiment 2 may include some or all of the steps in S2-1 to S2-3.

[0389] S2-1. The terminal receives second configuration information from the network-side device, including at least one of the following:

[0390] BWP deactivates the timer bwp-inactivityTimer;

[0391] Downlink BWP associated with an uplink BWP configured with random access resources.

[0392] For example, when a terminal initiates random access using the active UL BWP on the SpCell, the network-side device can instruct the terminal to use the DL BWP associated with the active UL BWP during the random access process. For instance, if a UE initiates RACH using the active UL BWP with bwp-ID=2 on the SpCell, and the network indicates that the UL BWP with bwp-ID=2 is associated with the DL BWP with bwp-ID=3, then the UE's random access on the SpCell will use both the active UL BWP with bwp-ID=2 and the active DL BWP with bwp-ID=3.

[0393] For example, when a terminal initiates random access on the active UL BWP of an SCell, the network-side device can instruct the terminal to use the SpCell DL BWP associated with the active UL BWP during the random access process. For instance, if a UE initiates RACH on the active UL BWP with bwp-ID=1 in an SCell, and the NW indicates that the SCell UL BWP with bwp-ID=1 is associated with the SpCell DL BWP with bwp-ID=4, then the UE's random access on the SCell will use both the active UL BWP with bwp-ID=1 and the active DL BWP with bwp-ID=4.

[0394] Optionally, when activating the multi-active BWP or multi-active DL BWP function, the network-side device may indicate the DL BWP associated with the UL BWP configured with random access resources.

[0395] This can be understood as follows: if the network-side device only activates a single-active downlink BWP, the UE will use this active DL BWP for random access. The network-side device does not need to separately indicate which active DL BWP the UE should use for downlink information when activating a multi-active DL BWP.

[0396] S2-2. The terminal initiates a random access procedure. Optionally, the terminal performs carrier selection in S2-2. Optionally, the terminal initiates a random access procedure in the serving cell.

[0399] The fifth operation includes performing a random access procedure using an activated first downlink BWP of the SpCell and an activated first uplink BWP of the serving cell, wherein random access resources are configured on the first uplink BWP.

[0400] Optionally, the terminal performs a fourth operation when initiating random access, including:

[0404] If the deactivation timers for all active downlink BWPs in the serving cell are running, the terminal stops the deactivation timers for all active downlink BWPs in the serving cell.

[0405] If the deactivation timers of all active downlink BWPs in the serving cell are running, the terminal stops the deactivation timer of the target downlink BWP of the serving cell.

[0406] If the deactivation timer of at least one active downlink BWP of the serving cell is running, the terminal stops the deactivation timers of all active downlink BWPs of the serving cell.

[0407] If the deactivation timer of at least one active downlink BWP of the serving cell does not run, the terminal does not stop the deactivation timers of all active downlink BWPs of the serving cell.

[0408] If the deactivation timer of at least one active downlink BWP of the serving cell is running, the terminal stops the deactivation timer of the target downlink BWP of the serving cell.

[0409] If the deactivation timer of at least one active downlink BWP of the serving cell does not run, the terminal does not stop the deactivation timer of the target downlink BWP of the serving cell.

[0410] If the serving cell has only one active downlink BWP, and the deactivation timer of the active downlink BWP is running, the terminal stops the deactivation timer of the active downlink BWP.

[0411] Optionally, the terminal performs the fourth operation based on the running status of the deactivation timer for the partially or fully activated downlink BWP in SpCell, including at least one of the following:

[0412] If all active downlink BWPs in the SpCell are running deactivation timers, the terminal stops all active downlink BWPs in the SpCell.

[0413] If all active downlink BWPs of the SpCell are running deactivation timers, the terminal stops the deactivation timer of the target downlink BWP of the SpCell.

[0414] If the deactivation timer of at least one active downlink BWP of the SpCell is running, the terminal stops the deactivation timers of all active downlink BWPs of the SpCell.

[0415] If the deactivation timer of at least one active downlink BWP of the SpCell does not run, the terminal does not stop the deactivation timers of all active downlink BWPs of the SpCell.

[0416] If the deactivation timer of at least one active downlink BWP of the SpCell is running, the terminal stops the deactivation timer of the active target downlink BWP of the SpCell.

[0418] If the SpCell has only one active downlink BWP, and the deactivation timer of the active downlink BWP is running, the terminal stops the deactivation timer of the active downlink BWP.
