[0124] Figure 2 is an interactive schematic diagram of an information receiving or sending method according to an embodiment of the present disclosure. As shown in Figure 2, the embodiments of the present disclosure relate to an information receiving or sending method, which includes:

[0125] Step S2101: The terminal records the first identifier of the first cell where the main receiver is located when it switches from wake-up state to sleep state.

[0126] In some embodiments, the first cell refers to the cell in which the terminal's primary receiver switches from a wake-up state to a sleep state. Optionally, the first cell can be understood as the terminal's serving cell, and the first identifier is the identifier of the serving cell. In some embodiments, the wake-up state means that the primary receiver is in an active state, and the terminal can receive or send data based on the primary receiver. In some embodiments, the sleep state means that the primary receiver is not in an active state, and the terminal cannot receive or send data based on the primary receiver.

[0127] In this embodiment of the disclosure, when the terminal determines that the main receiver has switched from a wake-up state to a sleep state, the terminal records the first identifier of the first cell in which it is currently located.

[0128] In some embodiments, the first identifier includes a cell identifier or a region identifier, wherein the region identifier indicates a region that includes one or more cells indicated by the cell identifier.

[0129] In some embodiments, the master receiver is an LP-WUR. The LP-WUR can support at least two types. One type of LP WUR only supports envelope detection of OOK (On Off Keying) symbols of LP WUS (Low Power Wake Up Signal), hereinafter referred to as OOK LR. This receiver has relatively poor link performance. Another type of LP WUR can detect the OFDM (Orthogonal Frequency Division Multiplexing) time-domain or frequency-domain sequence (i.e., overlaid OFDM sequence) carried by the OOK symbols of LP WUS, thereby improving link performance; this is referred to as OFDM LR. OFDM LR may also be able to detect PSS (Primary Synchronization Signal) / SSS (Secondary Synchronization Signal) sequences in existing protocols. However, if the PSS / SSS is not in the frequency band supported by the OFDM LR, the OFDM LR cannot receive the PSS / SSS.

[0130] In some embodiments, when there is no downlink information to receive or uplink information to send, the terminal can switch the main receiver from a wake-up state to a sleep state. In other embodiments, when the terminal is in power-saving mode, the terminal can switch the main receiver from a wake-up state to a sleep state. It should be noted that the embodiments disclosed herein are illustrative examples, and the terminal can switch the main receiver from a wake-up state to a sleep state in other circumstances, which are not limited in this disclosure.

[0131] In some embodiments, to properly detect LP WUS, the terminal obtains the time and frequency location of the LP WUS transmitted by the network device. The terminal can obtain and maintain time and frequency synchronization by detecting a synchronization signal. When MR is enabled, the terminal obtains synchronization by detecting the synchronization signal SSB. When MR is disabled and LR is enabled, synchronization is maintained by a low-power synchronization signal (LP-SS) specifically for LP WUS (for LR that can perform OFDM signal detection, synchronization can also continue to be maintained by SSB). In addition to being used for synchronization, LP-SS can also be used as a reference signal for RRM (Radio Resource Management) measurements.

[0132] In some embodiments, network devices can broadcast the frequency domain positions of the cell's LP WUS and LP-SS (Low Power Synchronization Signal) to terminals via system information. Terminals in RRC idle state can obtain the configuration information (including frequency domain position, time domain position, power information, etc.) of the cell's LP WUS / LP-SS by listening to the system information. In this way, when the terminal determines that it is entering MR sleep state, it can use LR to listen to LP-SS / LP WUS at the configured frequency domain / time domain positions.

[0133] Optionally, LP-SS configuration is per-cell, meaning each cell can be configured with its own LP-SS. It's possible for a cell to have an LP-SS while its neighboring cells do not. The frequency domain locations of the LP-SS in different cells may be the same or different. The power of the LP-SS in different cells may also be the same or different. The LP-SS may contain cell ID information.

[0134] In step S2102, the terminal determines the second cell in which the main receiver is located when it switches from sleep mode to wake-up mode.

[0135] Optionally, the second cell refers to the cell in which the terminal's main receiver switches from sleep mode to wake-up mode.

[0136] In some embodiments, the terminal has multiple ways to determine whether the main receiver switches from sleep state to wake-up state.

[0137] For example, a terminal receives a low-power wake-up signal from a network device via a low-power receiver, determining that its main receiver has switched from sleep mode to wake-up mode. In this embodiment of the disclosure, the network device can wake up the terminal's main receiver by sending a low-power wake-up signal. Optionally, the network device sends a low-power wake-up signal when it determines that there is downlink information that needs to be transmitted.

[0138] For example, when the terminal confirms that it has uplink transmission resources, it determines that the terminal's main receiver switches from sleep mode to wake-up mode. In this embodiment of the present disclosure, if the terminal has uplink transmission resources, the terminal needs to send uplink information through the main receiver, therefore the terminal determines that the main receiver switches from sleep mode to wake-up mode.

[0139] For example, when the terminal confirms that the signal quality of the low-power receiver is lower than a quality threshold, it determines that the terminal's main receiver switches from sleep mode to wake-up mode. Optionally, the quality threshold is used to indicate the threshold at which the low-power receiver cannot normally send or receive information. Optionally, this quality threshold is configured by the network device or agreed upon by the communication protocol, and this disclosure embodiment does not limit this.

[0140] In some embodiments, the second identifier includes a cell identifier or a region identifier, wherein the region identifier indicates a region that includes one or more cells indicated by the cell identifier.

[0141] In some embodiments, the first identifier of the first cell and the second identifier of the second cell can be the same or different. Optionally, the first identifier and the second identifier are area identifiers. If the first identifier and the second identifier are the same, then for the first cell and the second cell with the same first identifier and second identifier, at least one of the following information is the same for the first cell and the second cell:

[0142] (1) Temporal resources for paging timing.

[0143] In some embodiments, the time-domain resource for paging timing is a PF (Paging Frame) or PO (Paging Occasion) time-domain resource.

[0144] (2) Paging search space.

[0145] In some embodiments, the paging search space is the paging search space.

[0146] (3) Low-power reference signal configuration.

[0147] For example, the low-power reference signal may include, but is not limited to, LP-SS. Alternatively, LP-SS can be considered a type of low-power reference signal. It should be noted that the LP-SS in this embodiment is merely illustrative, and this embodiment does not limit the low-power reference signal to LP-SS; the low-power reference signal can be other signals. For example, the low-power reference signal may be LP-SS, and the low-power reference signal configuration may include an LP-SS configuration.

[0148] (4) Low-power wake-up signal configuration.

[0149] In some embodiments, the low-power reference signal configuration includes an LP WUS configuration.

[0150] (5) Time domain resources for paging advance instructions.

[0151] In some embodiments, the time-domain resources for paging early indication include the PEI (paging early indication) time-domain location.

[0152] (6) Search space for advance paging instructions.

[0153] In some embodiments, the search space for advance paging indication includes a PEI search space configuration.

[0154] (7) The time of network devices located within the first and second identifiers.

[0155] (8) Configuration associated with random access.

[0156] It should be noted that the above embodiments are described with at least one piece of information (1)-(8) being the same. In another embodiment, the area identifier of the first cell is the same as the area identifier of the second cell, which can be understood as the information (1)-(8) in the above embodiments being the same.

[0157] In some embodiments of this disclosure, after the main receiver of the terminal is woken up, there are multiple scenarios for determining the second cell.

[0158] Optionally, if the main receiver and the terminal's low-power receiver are on the same frequency band or carrier, the second cell is the cell indicated by the cell identifier included in the low-power reference signal received by the low-power receiver. In this embodiment, the main receiver and the terminal's low-power receiver are always deployed on the same band or carrier. In this case, when the main receiver is in sleep mode or the low-power receiver is working, the terminal can determine the ID of the cell corresponding to the LP-SS through the cell ID information carried in the LP-SS. After the main receiver wakes up, it can directly receive the SSB (Synchronization Signaling Block) and other signals of that cell on the same band / carrier. The second cell is the cell corresponding to the cell ID carried in the LP-SS that the low-power receiver is listening to.

[0159] Optionally, the main receiver and the terminal's low-power receiver operate on different frequency bands or carriers. The frequency band or carrier of the main receiver and the frequency band or carrier of the low-power receiver are bound together. The second cell is the cell indicated by the cell identifier included in the low-power reference signal received by the low-power receiver. In this embodiment, the main receiver and the terminal's low-power receiver can be deployed on different bands or carriers, but there is a predetermined binding relationship between the band or carrier where the low-power receiver is located and the band or carrier where the main receiver is located. In this case, when the main receiver is in sleep mode or the low-power receiver is working, the terminal can determine the cell ID corresponding to the LP-SS through the cell ID information carried in the LP-SS. After the main receiver wakes up, it directly receives the SSB and other signals of that cell on the band or carrier bound to the band or carrier where the LP-SS is located. The second cell is the cell corresponding to the cell ID carried in the LP-SS that the low-power receiver is listening to. However, the spectrum resources occupied by the legacy NR channels of this second cell are different from the spectrum resources of the LP-SS.

[0160] Optionally, the main receiver and the terminal's low-power receiver operate on different frequency bands or carriers, and there is no binding relationship between the frequency band or carrier of the main receiver and the frequency band or carrier of the low-power receiver. The second cell is a cell selected through a cell selection process. In this embodiment, the main receiver and the terminal's low-power receiver can be deployed on different bands or carriers, and there is no predetermined binding relationship between the band or carrier where the low-power receiver is located and the band or carrier where the main receiver is located. In this case, when the main receiver and the terminal's low-power receiver are working, the terminal can determine the ID of the cell corresponding to the LP-SS through the cell ID information carried in the LP-SS. However, after the main receiver is woken up, the main receiver does not know the frequency domain location of the cell corresponding to the LP-SS. Therefore, the terminal selects the second cell by performing a cell search at the supported frequency locations.

[0161] In step S2103, the terminal determines whether to listen for downlink information or send uplink information after waking up, based on whether the first identifier of the first cell and the second identifier of the second cell are the same.

[0162] In some embodiments, monitoring downlink information refers to monitoring paging information. For example, the paging information may be paging DCI or other information, which is not limited in this disclosure.

[0163] It should be noted that the monitoring in this embodiment can also be understood as receiving, that is, receiving downlink information after the terminal is woken up.

[0164] In some embodiments, sending uplink information refers to sending random access information. Optionally, the random access information refers to information used for PRACH, or other information, which is not limited in this disclosure.

[0165] In some embodiments, determining the method for monitoring downlink information or sending uplink information based on whether the first identifier of the first cell and the second identifier of the second cell are the same includes: if the first identifier and the second identifier are the same, monitoring downlink information or sending uplink information based on the system information of the first cell. Optionally, the first identifier and the second identifier being the same includes: the cell identifier of the first cell being the same as the cell identifier of the second cell. Alternatively, the area identifier of the first cell being the same as the area identifier of the second cell. In some embodiments, the system message of the first cell includes at least one of the following: time-domain resources for paging timing, paging search space, low-power reference signal configuration, low-power wake-up signal configuration, time-domain resources for paging advance indication, and paging advance indication search space.

[0166] Optionally, listening to downlink information or sending uplink information based on the system information of the first cell includes: listening to downlink information or sending uplink information based on the system information of the first cell after a first time delay. Here, the first time delay refers to the delay at which the terminal is woken up. Alternatively, it can be understood as the terminal listening to downlink information or sending uplink information based on the system information of the first cell after being woken up and after the first time delay.

[0167] In some embodiments, determining the method for monitoring downlink information or sending uplink information based on whether the first identifier of the first cell and the second identifier of the second cell are the same includes: if the first identifier and the second identifier are different, obtaining the system information of the second cell, and monitoring downlink information or sending uplink information based on the system information of the second cell. Optionally, the first identifier and the second identifier being different includes: the cell identifier of the first cell and the cell identifier of the second cell being different. Or, the area identifier of the first cell and the area identifier of the second cell being different. In some embodiments, the system information of the second cell includes system information such as MIB (Master Information Block) and SIB (System Information Blocks).

[0168] It should be noted that when the main receiver and the terminal's low-power receiver are on different frequency bands or carriers, and the frequency band or carrier of the main receiver is bound to the frequency band or carrier of the low-power receiver, the first identifier and the second identifier are different. The system information of the second cell is obtained, and downlink information is monitored or uplink information is sent based on the system information of the second cell.

[0169] Optionally, listening to downlink information or sending uplink information based on the system information of the second cell includes: listening to downlink information or sending uplink information based on the system information of the second cell after a first delay and a second delay. Here, the first delay refers to the delay at which the terminal is woken up, and the second delay refers to the delay at which the terminal obtains the system information of the second cell.

[0170] Optionally, the first and second delays can also be referred to as a fourth delay. Therefore, listening to downlink information or sending uplink information based on the system information of the second cell after the first and second delays can be understood as listening to downlink information or sending uplink information based on the system information of the second cell after the fourth delay. This fourth delay includes the delay of the terminal being woken up and the delay of the terminal obtaining the system information of the second cell. Alternatively, the fourth delay may be greater than the delay of the terminal being woken up.

[0171] In some embodiments, determining the method of listening to downlink information or sending uplink information based on whether the first identifier of the first cell and the second identifier of the second cell are the same includes: if the first identifier and the second identifier are different, selecting the second cell through a cell selection process, obtaining the system information of the second cell, and listening to downlink information or sending uplink information based on the system information of the second cell.

[0172] It should be noted that when the main receiver and the terminal's low-power receiver are on different frequency bands or carriers, and there is no binding relationship between the frequency band or carrier of the main receiver and the frequency band or carrier of the low-power receiver, the first identifier and the second identifier are different. The second cell is selected through the cell selection process, the system information of the second cell is obtained, and downlink information is listened to or uplink information is sent based on the system information of the second cell.

[0173] Optionally, listening to downlink information or sending uplink information based on the system information of the second cell includes: listening to downlink information or sending uplink information based on the system information of the second cell after a first delay, a second delay, and a third delay. The first delay refers to the delay when the terminal is woken up, the second delay refers to the delay when the terminal obtains the system information of the second cell, and the third delay refers to the delay of the cell selection process.

[0174] Optionally, the first, second, and third delays can also be referred to as the fifth delay. Therefore, listening to downlink information or sending uplink information based on the system information of the second cell after the first, second, and third delays can be understood as listening to downlink information or sending uplink information based on the system information of the second cell after the fifth delay. This fifth delay includes the delay of the terminal being woken up, the delay of the cell selection process, and the delay of the terminal obtaining the system information of the second cell. Alternatively, the fifth delay may be greater than the delay of the terminal being woken up.

[0175] In step S2104, the network device sends downlink information to the terminal multiple times.

[0176] In this embodiment of the disclosure, the above method provides multiple ways to monitor downlink information, and correspondingly, the network device will also send downlink information multiple times in different ways.

[0177] In some embodiments, sending downlink information to the terminal multiple times includes: sending downlink information multiple times within a first delay after the terminal confirms that it has been woken up and after the first delay after the terminal confirms that it has been woken up, where the first delay refers to the delay after the terminal is woken up.

[0178] In some embodiments, sending downlink information to the terminal multiple times includes: sending downlink information multiple times within a first delay and a second delay after the terminal confirms being woken up, and after the first delay and the second delay after the terminal confirms being woken up. The first delay refers to the delay when the terminal is woken up, and the second delay refers to the delay when the terminal obtains system information of the second cell.

[0179] In some embodiments, sending downlink information to the terminal multiple times includes: sending downlink information multiple times within the first, second, and third delays during which the terminal confirms being woken up, and after the first, second, and third delays during which the terminal confirms being woken up. The first delay refers to the delay during which the terminal is woken up, the second delay refers to the delay during which the terminal acquires the second cell, and the third delay refers to the delay during the cell selection process.

[0180] Step S2105: The terminal listens to downlink information based on a determined method of listening to downlink information.

[0181] It should be noted that this embodiment of the disclosure uses the terminal listening to downlink information in steps S2104-S2105 as an example for illustration. In another embodiment, the terminal can also send uplink information based on a determined method of sending uplink information, and the network device receives the uplink information sent by the terminal.

[0182] In some embodiments, receiving uplink information sent by the terminal includes: receiving uplink information sent by the terminal within a first delay after the terminal confirms being woken up and after the first delay after the terminal confirms being woken up, wherein the first delay refers to the delay after the terminal is woken up.

[0183] In some embodiments, receiving uplink information sent by the terminal includes: receiving uplink information sent by the terminal within a first delay and a second delay after the terminal confirms being woken up, and after the first delay and the second delay after the terminal confirms being woken up, wherein the first delay refers to the delay after the terminal is woken up, and the second delay refers to the delay after the terminal obtains system information of the second cell.

[0250] Step S5101: The network device sends downlink information to the terminal multiple times or receives uplink information sent by the terminal.

[0251] Step S5101 is similar to step S2104 above, and will not be described again here.

[0252] In step S5102, the terminal determines whether to listen for downlink information or send uplink information after waking up, based on whether the first identifier of the first cell and the second identifier of the second cell are the same.

[0253] Step S5102 is similar to step S2103 above, and will not be described again here.

[0254] Figure 6 is a flowchart illustrating an information receiving or sending method according to an embodiment of the present disclosure. As shown in Figure 6, the present disclosure relates to an information receiving or sending method, which includes:

[0255] In step S6101, the terminal needs to record the cell ID or area ID of the cell (first cell) in which it transitions from MR working state to MR sleep / LR active state.

[0256] In some embodiments, a single cell contains identical system information configurations. However, different cells may have the same or different system information configurations. Therefore, the concept of an area is introduced here. An area can contain one or more cells. The explanation of an area is as follows: For cells with the same area ID, these cells can be considered to have partially or completely identical system information configurations, especially those related to listening to paging and initiating random access.

[0257] For example, they have the same PF / PO time domain resource configuration. For example, they have the same paging search space configuration. For example, they have the same LP WUS / LP-SS configuration. For example, they have the same PEI (paging early indication) time domain location configuration. For example, they have the same PEI search space configuration. For example, they have the same timing. For example, they have the same random access related configurations.

[0258] In step S6102, the terminal determines the second cell where it resides after being woken up.

[0259] In some embodiments, Case 1: The LR and MR are always deployed on the same band / carrier. In this case, when the UE is in MR sleep mode / LR is active, it can determine the cell ID corresponding to the LP-SS through the cell ID information carried in the LP-SS. After the MR wakes up, it can directly receive the SSB and other signals of that cell on the same band / carrier. The second cell is the cell corresponding to the cell ID carried in the LP-SS that the LR is listening to.

[0260] In some embodiments, Case 2: The LR and MR can be deployed on different bands / carriers, but there is a predetermined binding relationship between the band / carrier where the LR is located and the band / carrier where the MR is located. In this case, when the UE is in MR sleep mode / LR is active, it can determine the cell ID corresponding to the LP-SS through the cell ID information carried in the LP-SS. After the MR wakes up, it directly receives the SSB and other signals of the cell on the band / carrier bound to the band / carrier where the LP-SS is located. The second cell is the cell corresponding to the cell ID carried by the LP-SS that the LR is listening to, but the spectrum resources occupied by the legacy NR channels of this cell are different from the spectrum resources of the LP-SS.

[0261] In some embodiments, Case 3: The LR and MR can be deployed on different bands / carriers, and there is no predetermined binding relationship between the band / carrier where the LR is located and the band / carrier where the MR is located. In this case, when the UE is in sleep mode / the LR is active, it can determine the cell ID corresponding to the LP-SS through the cell ID information carried in the LP-SS. However, after the MR wakes up, the MR does not know the frequency domain location of the cell corresponding to the LP-SS. Therefore, the UE can only select the second cell by performing a cell search at the supported frequency locations.

[0262] In some embodiments, when the terminal wakes up, if the terminal detects that the cell ID of the cell it resides in after wake-up (hereinafter referred to as "the second cell") is the same as the cell ID of the first cell (when neither the first cell nor the second cell has an area ID configured), or if the terminal detects that the area ID of the second cell is the same as the area ID of the first cell (when both the first cell and the second cell have area IDs configured), the terminal can directly listen for paging DCI based on the configuration of the system information stored in the first cell (configuration of PF / PO time domain position / PEI time domain position / PEI search space / paging search space). Specifically, after the terminal receives the LP WUS (or has uplink data to transmit / or needs to activate MR to enter working state due to insufficient LR listening signal quality), it can prepare to receive paging DCI after the wake-up delay. The wake-up delay is the time required from the terminal receiving the LP WUS wake-up instruction to the terminal activating its hardware and software functions to the point where it can normally perform PDCCH listening.

[0263] In some embodiments, under situations 1 and 2 above, when the terminal wakes up, if the terminal detects that the cell ID of the second cell is different from the cell ID of the first cell (when neither the first nor the second cell has an area ID configured), or if the terminal detects that the area ID of the second cell is different from the area ID of the first cell (when both the first and second cells have area IDs configured), the terminal needs to first listen to the system information of the second cell, and then listen to the paging DCI according to the PF / PO time domain position / PEI time domain position / PEI search space / paging search space configuration obtained from the system information of the second cell. That is, considering that the configuration of the second cell for the PF / PO time domain position / PEI time domain position / PEI search space / paging search space is likely to be different from that of the first cell, and the terminal did not obtain the system information of the second cell before waking up, the terminal needs to listen to the system information of the second cell after waking up to obtain the configuration information of the second cell, so as to listen to the paging DCI according to the corresponding configuration information. In Case 1, because the terminal needs to listen to system information before listening to paging DCI in the time domain, the time required for the terminal to go from receiving LP WUS to being able to listen to paging DCI is longer than in Case 2. In Case 2, after the terminal receives LP WUS (either because it has uplink data to transmit or because the quality of the LR listening signal is not good enough, requiring MR to be activated to enter the working state), it can only prepare to receive paging DCI after the wake-up delay plus the system information acquisition delay. Consider an example where the terminal only needs to listen to paging DCI and not PEI, since the PF / PO paging search space is in SIB1. The maximum propagation period of SIB1 is 160ms, and the number of repetitions within 160ms depends on the specific SSB configuration, so a possible example of system information acquisition delay is 160ms.

[0264] In some embodiments, under scenario 3 above, after the terminal wakes up, it needs to determine the second cell through a cell selection process. After determining the second cell, if the terminal detects that the cell ID of the second cell is different from the cell ID of the first cell (when neither the first nor the second cell has an area ID configured), or if the terminal detects that the area ID of the second cell is different from the area ID of the first cell (when both the first and second cells have area IDs configured), the terminal needs to first select the second cell through a cell selection process, then listen to the system information of the second cell, and then listen to the paging DCI based on the PF / PO time domain location / PEI time domain location / PEI search space / paging search space configuration obtained from the listened system information of the second cell. That is, considering that the configuration of the PF / PO time domain location / PEI time domain location / PEI search space / paging search space of the second cell may be different from that of the first cell, and the terminal did not obtain the system information of the second cell before waking up, the terminal needs to listen to the system information of the second cell after waking up to obtain the configuration information of the second cell, so as to listen to the paging DCI according to the corresponding configuration information. In Case 2, because the terminal needs to perform a cell selection process in the time domain, then listen to system information, and finally listen to paging DCI, the time required for the terminal to go from receiving LP WUS to being able to listen to paging DCI is longer. In Case 3, after the terminal receives LP WUS (either because it has uplink data to transmit or because the quality of the LR listening signal is not good enough, requiring MR to be activated to enter the working state), it can only prepare to receive paging DCI after the wake-up delay + cell selection process delay + system information acquisition delay. Considering that the cell selection process requires detection of 8 frequency points, listening to 5 SSBs on each frequency point, and the period of each SSB is 20ms, the cell selection process delay for 8 frequency points is about 700ms; for the system information listening process, considering that the terminal only needs to listen to paging DCI and not PEI, since the PF / PO paging search space is in SIB1. The maximum propagation period of SIB1 is 160ms, and the number of times it repeats within 160ms depends on the specific SSB configuration. Therefore, the system information acquisition delay can be considered to be 160ms.

[0265] In some embodiments, under deployment scenarios (1) and (2), since the terminal is in idle state, the base station is unaware whether the terminal is in Case 1 or Case 2 state upon wake-up, or even whether the terminal is using LR to listen to LP WUS or using MR. To ensure that the terminal can receive paging information in a timely manner, the base station needs to send one or more paging DCIs during the period after the wake-up delay ends, and also needs to send one or more paging DCIs during the period after the wake-up delay + system information acquisition delay ends.

[0266] In some embodiments, in the deployment scenario of case (3), since the terminal is in idle state, the base station is unaware whether the terminal is in Case 1 or Case 3 state when it is woken up, or even whether the terminal is using LR to listen to LP WUS or using MR. In order to ensure that the terminal can receive paging information in a timely manner, the base station needs to send one or more paging DCIs during the period after the wake-up delay ends, and also needs to send one or more paging DCIs during the period after the wake-up delay + cell selection process delay + system information acquisition delay ends.

[0267] This disclosure also proposes an apparatus (also referred to as a communication device, etc.) for implementing any of the above methods. For example, an apparatus is proposed that includes units or modules for implementing the steps performed by the terminal in any of the above methods.

For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
