Description

Handover delay determination method, device, equipment, storage medium and chip Technical Field

[0001] The present disclosure relates to the field of communication technologies, and in particular to a method, apparatus, device, storage medium, and chip for determining a handover delay. Background Art

[0002] The network device configures the terminal equipment (User Equipment, UE) with different search space set groups (Search Space Set Group, SSSG) with different PDCCH (physical downlink control channel, downlink control channel) monitoring periods to achieve the purpose of energy saving on the terminal side. When the terminal equipment has more intensive uplink and downlink services, a more intensive period configuration will be used to monitor the PDCCH. The network device configures multiple search space sets (Search Space Sets) into different search space set groups (Search Space Set Group, SSSG), and can instruct the UE through PDCCH which group of SSSG configurations to use for PDCCH monitoring. The network device can directly trigger the UE to switch the SSSG through PDCCH, and the UE switches the SSSG according to the switching delay configured by the network device.

[0003] In related technologies, in order to save UE costs, the UE's processing capability is reduced. However, when the UE's processing capability is reduced, if the network device configures the switching delay for the UE according to the processing capability of the traditional terminal device, it may cause the UE to be unable to complete the switching between SSSGs using a shorter configured delay.

[0044] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0045] It is understood that in this disclosure, "plurality" refers to two or more than two, and other quantifiers are similar. "And / or" describes the association relationship of related objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the related objects before and after are in an "or" relationship. The singular forms "a", "the" and "the" are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0046] It should be further understood that the terms "first," "second," and the like are used to describe various types of information, but such information should not be limited to these terms. These terms are used solely to distinguish information of the same type from one another and do not imply a particular order or level of importance. In fact, the terms "first," "second," and the like are fully interchangeable.

[0047] It is further understood that although operations are described in a particular order in the drawings in the embodiments of the present disclosure, this should not be construed as requiring that the operations be performed in the particular order shown or in a serial order, or that all of the operations shown be performed to obtain the desired results. In certain circumstances, multitasking and parallel processing may be advantageous.

[0048] It should be noted that all actions of acquiring signals, information or data in this application are carried out in compliance with the relevant data protection laws and policies of the country where they are located and with the authorization given by the owner of the corresponding device.

[0049] To facilitate understanding, the terms involved in this disclosure are first introduced.

[0050] 1. PDSCH (physical downlink shared channel): PDSCH is used to carry downlink higher-layer control signaling and user data.

[0051] 2. PUSCH (physical uplink shared channel): PUSCH is used to carry uplink high-layer / physical layer control signaling and user data.

[0052] 3. PUCCH (physical uplink control channel): PDCCH is used to carry Hybrid Automatic Repeat reQuest (HARQ) Acknowledgement / Negative Acknowledgement (ACK / NACK) messages.

[0053] 4. PDCCH (physical downlink control channel): The PDCCH channel transmits DCI (Downlink Control Information) related to the physical uplink and downlink shared channels (PUSCH, PDSCH). DCI information includes several related contents such as RB (Resource Block) allocation information and HARQ requests. Only when the terminal device correctly decodes the DCI information can it correctly process PDSCH or PUSCH data.

[0054] 5. BWP (Band Bidth Part): BWP is a subset of the terminal device channel bandwidth. It flexibly adjusts the terminal device's receive and transmit bandwidth through bandwidth adaptation in NR (New Radio), so that the terminal device's receive and transmit bandwidth does not need to be as large as the cell's bandwidth. The terminal can only activate one UL (uplink) BWP and one DL (downlink) BWP at the same time. Each BWP is configured with an SCS (Sub-Carrier Spacing). Unless otherwise specified, all signals and channels on the BWP use the SCS.

[0055] 6. SSSG (Search Space Set Group). The UE uses SSSG to monitor PDCCH. The UE can switch SSSG in two ways: Method 1. The network device triggers the UE to switch SSSG through PDCCH; Method 2. The UE is triggered to switch SSSG by a timer. For example, during the period when the timer is running, one group of SSSG configurations is used to monitor PDCCH. When the timer expires, another group of SSSG is used to monitor PDCCH.

[0056] FIG1 is a flow chart showing a method for determining a handover delay according to an exemplary embodiment. The method for determining a handover delay is applied to a network device. As shown in FIG1 , the method for determining a handover delay includes the following steps.

[0057] In step S101 , the search space set group switching capability of the terminal device is determined.

[0058] Among them, the terminal device proposed in any embodiment of the present disclosure can be a mobile phone, a tablet, a portable computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, etc. The present disclosure does not limit the application scenario, and the terminal device may sometimes also be referred to as user equipment, terminal, access terminal, UE unit, UE station, mobile device, mobile station, mobile station, mobile client, etc.

[0059] Among them, the network device proposed in any embodiment of the present disclosure can be a device for communicating with a terminal device. The network device can also be called an access network device or a wireless access network device. It can be a transmission reception point (TRP), an evolved NodeB (eNB or eNodeB) in an LTE system, a home base station (for example, home evolved NodeB, or home Node B, HNB), a base band unit (BBU), or a wireless controller in a cloud radio access network (CRAN) scenario, or the network device can be a relay station, an access point, a vehicle-mounted device, a wearable device, a network device in a 5G network, or a network device in a future evolved PLMN network, etc. It can be an access point (AP) in a WLAN, or a gNB of an NR, and the embodiments of the present application are not limited.

[0060] The switching capability is the ability of a terminal device to switch between SSSGs. This switching capability is positively correlated with the processing capability of the terminal device. The stronger the processing capability of the terminal device, the stronger the switching capability of the terminal device to the SSSG and the shorter the switching delay of the terminal device to the SSSG. In the following description, the switching capability will be referred to as the processing capability. A service cell can access multiple terminal devices, including first-category terminal devices and second-category terminal devices.

[0061] The first category of terminal equipment is a terminal equipment whose processing capability is not relaxed. For example, the first category of terminal equipment (non-eRedCap UE) can be a terminal equipment with ordinary reduced capability (RedCap UE), an ordinary terminal equipment (Normal UE), etc.; the terminal equipment with not relaxed processing capability is a terminal equipment whose processing capability of the physical layer channel or physical layer signal is not relaxed, that is, the terminal equipment whose processing capability is not reduced or is normally reduced, and the switching delay of switching SSSG is shorter.

[0062] The second category of terminal devices may be terminal devices with relaxed processing capabilities, such as the evolved reduced processing capability terminal devices (eRedCap UE) in 3GPP Release 18 and later versions. A terminal device with relaxed processing capabilities is a terminal device with relaxed processing capabilities for physical layer channels or physical layer signals. The processing capabilities of a terminal device with relaxed processing capabilities are reduced compared to the processing capabilities of a terminal device without relaxed processing capabilities. Accordingly, the switching delay of a terminal device with relaxed processing capabilities switching SSSG is longer than the switching delay of a terminal device without relaxed processing capabilities switching SSSG.

[0063] Among the two types of terminal devices, namely non-eRedCap UE and eRedCap UE, for the processing capabilities of each terminal device, the relationship can be that the minimum processing capability of non-eRedCap UE > the minimum processing capability of eRedCap UE; for the switching delay of each terminal to switch SSSG, the relationship can be that the minimum switching delay corresponding to the minimum processing capability of non-eRedCap UE < the minimum switching delay corresponding to the minimum processing capability of eRedCap UE.

[0064] Among them, the switching delay is the switching duration allocated by the network device for the terminal device to switch SSSG. This switching delay is affected by the PDCCH blind detection delay and the PUCCH preparation delay, both of which are related to the PDSCH processing delay. The PDSCH processing delay includes the PDCCH blind detection delay, the PDSCH decoding delay, and the PUCCH preparation delay. The longer the PDSCH processing delay, the longer the corresponding switching delay of SSSG. Therefore, when the network device allocates the switching delay for the terminal device to switch SSSG, it needs to consider the PDSCH processing duration of the terminal device.

[0065] In step S102, according to the minimum switching delay corresponding to the search space set group switching capability, send the target switching delay to the terminal device.

[0066] Among them, the minimum switching delays corresponding to terminal devices with different SSSG processing capabilities are different, and there are multiple minimum switching delays corresponding to terminal devices with the same processing capability. These multiple minimum switching delays are the same or different.

[0067] Exemplarily, the minimum switching delays corresponding to terminal devices with different processing capabilities are shown in Table 1.

[0068] Table 1 Minimum switching delay values

[0069]

[0070] [[ID=二十二]]It can be understood that each element and each corresponding relationship in Table 1 exist independently; these elements and corresponding relationships are exemplarily listed in the same table, but it does not mean that all elements and corresponding relationships in the table must exist simultaneously as shown in Table 1. The value of each element and each corresponding relationship therein is independent of the values or corresponding relationships of any other elements in Table 1. Therefore, those skilled in the art can understand that the value of each element and each corresponding relationship in this Table 1 are all independent embodiments.

[0071] Among them, the minimum switching delay of the first type of terminal equipment is not limited to the values ​​listed in Table 1, but can also be other values. This disclosure no longer gives examples one by one for the other values ​​of the minimum switching delay of the second type of terminal equipment and the minimum switching delay of the first type of terminal equipment.

[0072] In Table 1, there are multiple minimum handover delays for the first processing capability, and these minimum handover delays are the same; there are multiple minimum handover delays for the second processing capability, and these minimum handover delays are different. Because the first processing capability is smaller than the second processing capability, the multiple minimum handover delays corresponding to the first processing capability are greater than the multiple minimum handover delays corresponding to the second processing capability. The symbols in Table 1 are OFDM (Orthogonal Frequency Division Multiplexing) symbols.

[0073] There is a corresponding relationship between the μ value of the terminal device in Table 1 and the subcarrier spacing of the current BWP of the terminal device.

[0074] For example, the μ value of the terminal device can be obtained by the following formula (1).

[0075] Δf=2 u *15 (1)

[0076] Wherein, Δf is the subcarrier spacing, μ is the μ value of the terminal device, which can be 0, 1, 2, 3, 4….

[0077] It can be seen from formula (1) that after determining the subcarrier spacing of the terminal device's current BWP, the network device can determine the μ value of the terminal device, and then determine a row in Table 1 based on the μ value of the terminal device; after determining the search space set group switching capability of the terminal device, the network device can determine a column in Table 1, and based on the determined row and column, a minimum switching delay can be determined.

[0078] Among them, the minimum switching delay corresponding to the first processing capability and the second processing capability can be the minimum switching delay applicable to the first type of terminal equipment, that is, the terminal equipment whose processing capability is not relaxed. The RedCap UE and the Normal UE have the same processing capability. The RedCap UE can have the first processing capability and the second processing capability, and the Normal UE can also have the first processing capability and the second processing capability. In the related art, in order to save energy consumption of the first type of terminal equipment, the PDSCH processing capability of the first type of terminal equipment will be reduced, so that the PDSCH processing time of the first type of terminal equipment is relaxed to N times the original time. After the PDSCH processing time is relaxed, the blind detection delay of the PDCCH will also be relaxed. For example, the bandwidth of the evolved eRedCap UE with reduced processing capability under the R18 standard is further reduced to 5MHZ compared to the bandwidth of the ordinary reduced-capability terminal equipment RedCap UE and the ordinary terminal equipment Normal UE under the R17 standard. At the same time, the PDSCH processing time is relaxed, so that the processing capability of the terminal equipment under the R18 standard is lower than that of the terminal equipment under the R17 standard and the R16 standard.

[0079] However, when the first type of terminal device without relaxed processing capability evolves into the second type of terminal device with relaxed processing capability, if the network device still allocates switching delay for the second type of terminal device based on the minimum switching delay required by the first type of terminal device, the switching delay allocated by the network device will not be aligned with the switching delay required by the second type of terminal device. That is, the switching delay allocated by the network device to the second type of terminal device may be smaller than the switching delay required by the second type of terminal device. At this time, the second type of terminal device with lower processing capability cannot complete the switching of SSSG based on the smaller switching delay. That is, the lower processing capability of the second type of terminal device cannot support the completion of SSSG switching with a smaller switching delay.

[0080] In order to avoid the situation where the switching delay allocated by the network device is not aligned with the switching delay required by the second type of terminal device, a column of minimum switching delays can be redefined in the network device. For details, refer to the following Table 2.

[0081] Table 2 Minimum switching delay values

[0082]

[0083] It is understood that each element and each corresponding relationship in Table 2 exists independently; these elements and corresponding relationships are illustratively listed in the same table, but this does not mean that all elements and corresponding relationships in the table must exist simultaneously as shown in Table 2. The value of each element and each corresponding relationship is independent of the value of any other element or corresponding relationship in Table 2. Therefore, those skilled in the art will understand that the value of each element and each corresponding relationship in Table 2 is an independent embodiment.

[0084] The minimum switching delay for the second type of terminal equipment in Table 2 is not limited to M1, M2, and M3, but can also be the values ​​represented by other symbols. Table 2 is only an example. The minimum switching delay for the first type of terminal equipment is not limited to the values ​​listed in Table 2, but can also be other values. This disclosure will not cite other values ​​of the minimum switching delay for the second type of terminal equipment and the minimum switching delay for the first type of terminal equipment one by one. The symbols in Table 1 are OFDM (Orthogonal Frequency Division Multiplexing) symbols.

[0085] In Table 2, the third processing capability has multiple identical or different minimum switching delays M1, M2, and M3, etc. The terminal device with the third processing capability may be a second-category terminal device with a relaxed processing capability. When the μ value of the second-category terminal device is 0, the network device determines the minimum switching delay of the second-category terminal device to be M1. When the μ value of the second-category terminal device is 1, the network device determines the minimum switching delay of the second-category terminal device to be M2. When the μ value of the second-category terminal device is 2, the network device determines the minimum switching delay of the second-category terminal device to be M3. M1, M2, and M3 may be the same or different, and M1, M2, and M3 are all greater than the minimum switching delay of the first-category terminal device. For example, M1, M2, and M3 are greater than the minimum switching delay corresponding to the first processing capability.

[0086] Among them, after defining the minimum switching delay of the second type of terminal device, if the network device determines that the search space group switching capability of the terminal device is the third switching capability, then the target switching delay is sent to the second type of terminal device according to the minimum switching delay corresponding to the third switching capability.

[0087] The target switching delay sent by the network device is greater than or equal to the minimum switching delay and less than the maximum switching delay. The maximum switching delay can be 52, and of course it can also be other values. This disclosure does not limit this.

[0088] For example, when the network device determines that the minimum switching delay is M1, based on the scheduling state of the network device itself, a target switching delay can be determined within the integer range of [M1, 52] and sent to the terminal device.

[0089] Through the above technical solution, the network device can determine the SSSG switching capability of the terminal device, determine the minimum switching delay corresponding to the SSSG switching capability, and send the target switching delay to the terminal device based on the minimum switching delay. In this process, after the processing capability of the terminal device is reduced, the network device can also re-determine the processing capability of the terminal device, and send the target switching delay to the terminal device based on the minimum switching delay corresponding to the reduced processing capability of the terminal device, so that the terminal device with reduced processing capability can receive the corresponding target switching delay, thereby avoiding the situation where the target switching delay required by the terminal device is not aligned with the target switching delay configured by the network device.

[0090] FIG2 is a flow chart showing a method for determining a handover delay according to an exemplary embodiment. The method for determining a handover delay is applied to a network device. As shown in FIG2 , the method for determining a handover delay includes the following steps.

[0091] In step S201, the search space set group switching capability of the terminal device is determined.

[0092] For the embodiment of this step, please refer to the above-mentioned step S101 and will not be described in detail here.

[0093] Among them, the switching capability includes at least one of the first switching capability, the second switching capability and the third switching capability, the terminal device includes at least one of the first type of terminal device and the second type of terminal device, and the target switching delay is sent to the terminal device according to the minimum switching delay corresponding to the search space group switching capability, including at least one of the following steps S202, S203 and S204.

[0094] In step S202, a second target switching delay is sent to the first category terminal device and / or the second category terminal device according to the minimum switching delay corresponding to the second switching capability.

[0095] Among them, the first type of terminal equipment is a terminal equipment with non-relaxed processing capabilities, such as normal terminal equipment Normal UE, normal RedCap UE with reduced processing capabilities, etc.; the second type of terminal equipment is a terminal equipment with relaxed processing capabilities, such as evolved eRedCap UE with reduced processing capabilities.

[0096] The second switching capability / second processing capability can be an unrelaxed processing capability, which can be applicable to ordinary terminal equipment Normal UE with unrelaxed processing capability; when the processing capability of Normal UE is reduced and Normal UE evolves into RedCap UE, the second switching capability is applicable to ordinary RedCap UE with reduced processing capability; when the processing capability of RedCap UE is reduced and RedCap UE evolves into eRedCap UE, the second switching capability is applicable to the evolved eRedCap UE with reduced processing capability.

[0097] It is understandable that the second target handover delay can be the unrelaxed handover delay, applicable to normal terminal equipment (Normal UE) with unrelaxed processing delay. When the processing delay of the Normal UE is relaxed and the Normal UE evolves to a RedCap UE, the second target handover delay applies to normal RedCap UE with reduced processing capability. When the processing delay of the RedCap UE is relaxed and the RedCap UE evolves to an eRedCap UE, the second target handover delay applies to the evolved eRedCap UE with reduced processing capability. Therefore, the second target handover delay obtained based on the minimum handover delay corresponding to the second handover capability is applicable to the first category of terminal equipment and / or the second category of terminal equipment.

[0098] It can be understood that when the Normal UE evolves into a RedCap UE, the RedCap UE has two processing capabilities. The RedCap UE may not relax the processing capability or may reduce the processing capability normally. When the RedCap UE evolves into an eRedCap UE, the eRedCap UE has three processing capabilities. The eRedCap UE may evolve to reduce the processing capability, that is, further reduce the processing capability compared to the normal reduction of the processing capability, or may reduce the processing capability normally, or may not reduce the processing capability.

[0099] For example, the second type of terminal equipment is a terminal equipment with reduced capabilities that is evolved based on the first type of terminal equipment, so the second switching capability applicable to the first type of terminal equipment can also be applicable to the second type of terminal equipment.

[0100] Among them, when it is determined that the SSSG switching capability of the terminal device is the second switching capability, the first target switching delay can be sent to the first type of terminal device and / or the second type of terminal device according to the minimum switching delay corresponding to the second switching capability.

[0101] For example, when it is determined that the SSSG switching capability of the terminal device is the second switching capability, the second target switching delay can be sent to the terminal device based on multiple minimum switching delays such as 10, 12 and 22 corresponding to the second processing capability in Table 2. The terminal device is a first-class terminal device and / or a second-class terminal device.

[0102] In step S203, the first target switching delay is sent to the first type of terminal device and / or the second type of terminal device according to the minimum switching delay corresponding to the first switching capability.

[0103] Among them, the first switching capability / first processing capability can be an ordinary relaxed processing capability, the first switching capability is less than the second switching capability, or the first processing capability is less than the second processing capability, and the first switching capability can be applicable to RedCap UE with ordinary reduced processing capability; when the processing capability of RedCap UE is reduced and RedCap UE evolves into eRedCap UE, the first switching capability is applicable to the evolved eRedCap UE with reduced processing capability.

[0104] It is understood that the first target handover delay can be a normal relaxed handover delay applicable to RedCap UEs. When the processing delay of RedCap UEs is relaxed and RedCap UEs evolve to eRedCap UEs, the first target handover delay applies to the evolved eRedCap UEs with reduced processing capabilities. Therefore, the first target handover delay obtained based on the minimum handover delay corresponding to the first handover capability is applicable to first-category terminal devices and / or second-category terminal devices.

[0105] For example, the second type of terminal equipment is a terminal equipment with reduced capabilities that is evolved based on the first type of terminal equipment. Therefore, the first switching capability applicable to the first type of terminal equipment can also be applicable to the second type of terminal equipment.

[0106] Among them, when it is determined that the SSSG switching capability of the terminal device is the first switching capability, the first target switching delay can be sent to the first type of terminal device and / or the second type of terminal device according to the minimum switching delay corresponding to the first switching capability.

[0107] For example, when it is determined that the SSSG switching capability of the terminal device is the first switching capability, a first target switching delay greater than or equal to 25 can be sent to the terminal device based on the minimum switching delay of 25 corresponding to the first processing capability in Table 2. The terminal device is a first-class terminal device and / or a second-class terminal device.

[0108] Among them, since the minimum switching delay corresponding to the first processing capability is greater than the minimum switching delay corresponding to the second processing capability, and the first target switching delay is greater than the minimum switching delay corresponding to the first processing capability, and the second target switching delay is greater than the minimum switching delay corresponding to the second processing capability, the first target switching delay is greater than the second target switching delay.

[0109] In step S204, the third target switching delay is sent to the second type of terminal device according to the minimum switching delay corresponding to the third switching capability.

[0110] The third switching capability / third processing capability may be an evolved relaxed processing capability. The third switching capability is less than the first switching capability, or in other words, the third processing capability is less than the first processing capability. The third switching capability may be applicable to second-category terminal devices with evolved reduced processing capabilities, such as eRedCap UEs. Since RedCap UEs and Normal UEs in the first category of terminal devices do not have relaxed processing capabilities and do not possess the evolved relaxed processing capabilities, the third switching capability cannot be applied to RedCap UEs and Normal UEs in the first category of terminal devices.

[0111] Among them, when it is determined that the SSSG switching capability of the terminal device is the third switching capability, the third target switching delay can be sent to the second type of terminal device according to the minimum switching delay corresponding to the third switching capability.

[0112] For example, when it is determined that the SSSG switching capability of the terminal device is the third switching capability, the third target switching delay can be sent to the terminal device based on the minimum switching delays such as M1, M2 and M3 corresponding to the third processing capability in Table 2. The terminal device is a second-category terminal device.

[0113] Among them, since the minimum switching delay corresponding to the third processing capability is greater than the minimum switching delay corresponding to the first processing capability, and the third target switching delay is greater than the minimum switching delay corresponding to the third processing capability, and the first target switching delay is greater than the minimum switching delay corresponding to the first processing capability, the third target switching delay is greater than the first target switching delay.

[0114] For example, after determining the second handover capability of any terminal device among Normal UE, RedCap UE, and eRedCap UE, the network device will send the second target handover delay to the terminal device based on the minimum handover delay corresponding to the second handover capability. After determining the first handover capability of any terminal device among RedCap UE and eRedCap UE, the network device will send the first target handover delay to the terminal device based on the minimum handover delay corresponding to the first handover capability. After determining the third handover capability of the eRedCap UE, the network device will send the third target handover delay to the terminal device based on the minimum handover delay corresponding to the third handover capability. It is understood that the network device sends the target handover delay to the terminal device based on the handover capability of the terminal device it determines.

[0115] It is understandable that there is no order relationship among steps S202, S203, and S204. After the search space set group switching capability of the terminal device is determined, any one of steps S202, S203, and S204 can be executed.

[0116] Through the above technical solution, when the network device determines that the processing capability of the first type of terminal device is the first switching capability or the second switching capability, it will send the first target switching delay or the second target switching delay to the first type of terminal device according to the minimum switching delay corresponding to the first switching capability or the second switching capability; when the network device determines that the processing capability of the second type of terminal device is the first switching capability or the second switching capability or the third switching capability, it will send the first target switching delay or the second target switching delay or the third target switching delay to the second type of terminal device according to the minimum switching delay corresponding to the first switching capability or the second switching capability or the third switching capability, so that the first type of terminal device and the second type of terminal device with different processing capabilities can respectively obtain the corresponding target switching delay, thereby avoiding the situation where the target switching delay configured by the network device is not aligned with the switching delay required by the terminal device.

[0117] FIG3 is a flow chart showing a method for determining a handover delay according to an exemplary embodiment. The method for determining a handover delay is applied to a network device. As shown in FIG3 , the method for determining a handover delay includes the following steps.

[0118] In step S301, the search space set group switching capability of the terminal device is determined.

[0119] For the embodiment of this step, please refer to the above-mentioned step S101 and will not be described in detail here.

[0120] In step S302, the target switching delay is sent to the terminal device according to the minimum switching delay corresponding to the search space set group switching capability and the subcarrier spacing of the terminal device bandwidth.

[0121] Among them, when there are at least two types of terminal devices within the network coverage of the network device, it is necessary to determine a minimum switching delay based on the SSSG switching capability of the terminal device and the subcarrier spacing of the terminal device BWP, and send the target switching delay to the terminal device based on the minimum switching delay.

[0122] For example, in the case where the terminal devices within the network coverage of the network device include three types of terminal devices, namely Normal UE, RedCap UE and eRedCap UE, which are included in the first type of terminal devices and the second type of terminal devices, if the subcarrier spacing of the BWP of these three types of terminal devices is 100KHZ, the network device cannot determine which type of terminal device the configured target switching delay is based only on the subcarrier spacing of 100KHZ; if the network device only determines that the processing capability of the terminal device is the third processing capability, since there are multiple minimum switching delays under the third processing capability, the network device cannot determine the required minimum switching delay from the multiple minimum switching delays.

[0123] In order to determine the required minimum switching delay when there are multiple types of terminal devices, it is necessary to determine a minimum switching delay based on the SSSG switching capability of the network device and the subcarrier spacing of the BWP of the terminal device.

[0124] Among them, referring to the above formula (1), after determining the subcarrier spacing of the BWP of the terminal device, the μ value of the terminal device can be determined, and then a row in Table 2 can be determined; after determining the processing capability of the terminal device, a column in Table 2 can be determined, and finally a minimum switching delay can be determined based on the μ value of the terminal device and the subcarrier spacing of the BWP.

[0125] For example, when the μ value of the terminal device is determined to be 1 and the processing capability of the terminal device is the third processing capability, the minimum switching delay of the terminal device can be determined to be M2; and a target switching delay greater than or equal to M2 is sent to the terminal device.

[0126] The network device and the terminal device have unified the correspondence between the terminal device's processing capability, the terminal device's μ value, and the minimum switching delay. Specifically, the network device and the terminal device both define the correspondence between the terminal device's processing capability, the terminal device's μ value, and the minimum switching delay as shown in Table 2. For example, the network device and the terminal device both define the correspondence between the terminal device's μ value, the third processing capability, and the minimum switching delay. Thus, once the network device determines the terminal device's processing capability and the terminal device's μ value, it can directly determine the minimum switching delay and then return the target switching delay required by the terminal device.

[0127] In any embodiment of the present disclosure, the target switching delay needs to be within the range of values ​​between the minimum processing delay and the maximum processing delay, that is, within the range of values ​​greater than or equal to the minimum processing delay and less than the maximum processing delay, and the value is determined according to the scheduling situation of the network device.

[0128] Among them, the multiple minimum switching delays under the third processing capability are greater than the multiple minimum switching delays under the first processing capability. For example, the multiple minimum switching delays under the third processing capability can be N times the multiple minimum switching delays under the first processing capability. The multiple minimum switching delays under the third processing capability can also be the sum of the multiple minimum switching delays under the first processing capability and a preset value, and the preset value is a positive number.

[0129] The minimum switching delay corresponds to the processing capability of the terminal device and is the fastest delay at which the terminal device can switch to the SSSG under the current processing capability. Of course, the terminal device can also switch to the SSSG with a delay greater than or equal to the minimum switching delay, or with a delay slower than the minimum switching delay. Therefore, the network device can configure a target switching delay greater than or equal to the minimum switching delay for the terminal device. It is understandable that the terminal device cannot switch to the SSSG using a switching delay that does not match the processing capability of the terminal device. For example, the terminal device cannot switch to the SSSG using a target switching delay that is less than the minimum switching delay.

[0130] Through the above technical solution, when there are at least two types of terminal devices within the network coverage of the network device, a minimum switching delay can be determined from multiple minimum switching delays based on the SSSG switching capability of the network device and the subcarrier spacing of the BWP of the terminal device, and then a target switching delay greater than or equal to the minimum switching delay is sent to the terminal device.

[0131] FIG4 is a flow chart showing a method for determining a handover delay according to an exemplary embodiment. The method for determining a handover delay is applied to a network device. As shown in FIG4 , the method for determining a handover delay includes the following steps.

[0132] In step S401, the search space set group switching capability of the terminal device is determined.

[0133] For the embodiment of this step, please refer to the above-mentioned step S101 and will not be described in detail here.

[0134] In step S402, when the type of the terminal device is the target type, the target switching delay is sent to the terminal device according to the minimum switching delay corresponding to the subcarrier spacing of the terminal device bandwidth.

[0135] Among them, when the type of terminal device within the network coverage of the network device is only the target type, the network device itself knows the processing capability of the terminal device of the target type, and there is no need to determine the processing capability of the terminal device. Therefore, the terminal device can determine a minimum switching delay based on the subcarrier spacing of the terminal device's current BWP.

[0136] The target type may be the Normal UE and RedCap UE included in the first category of terminal equipment, or the eRedCap UE included in the second category of terminal equipment.

[0137] The network device is pre-installed with the processing capability of the target type of terminal device.

[0138] For example, when the only terminal device within the network coverage of the network device is Normal UE and the subcarrier spacing of the terminal device is 100KHZ, the network device itself knows that the processing capability of the Normal UE is the second processing capability. At this time, based on the subcarrier spacing of the Normal UE of 100KHZ, it can be determined that the μ value of the Normal UE is 2, and then the minimum switching delay corresponding to 2 is determined to be 22.

[0139] For example, when the only terminal device within the network coverage of the network device is the eRedCap UE and the subcarrier spacing of the terminal device is 100KHZ, the network device itself knows that the processing capability of the eRedCap UE is the third processing capability. At this time, based on the subcarrier spacing of the eRedCap UE of 100KHZ, the μ value of the Normal UE can be determined to be 2, and then the minimum switching delay corresponding to 2 can be determined to be M3.

[0140] Through the above technical solution, when there are only target-type terminal devices within the coverage of the network device, the processing capabilities of the target-type terminal devices can be preset in the network device. When the network device needs to allocate a target switching delay for the terminal device, it is only necessary to determine the μ value of the terminal device based on the subcarrier spacing, and then determine the minimum switching delay corresponding to the μ value from multiple minimum switching delays under the preset terminal device processing capability based on the μ value, without determining the processing capability of the terminal device, that is, there is no need for the terminal device to report the processing capability of the terminal device to the network device.

[0141] FIG5 is a flow chart showing a method for determining a handover delay according to an exemplary embodiment. The method for determining a handover delay is applied to a network device. As shown in FIG5 , the method for determining a handover delay includes the following steps.

[0142] In step S501, the search space set group switching capability reported by the terminal device is received.

[0143] In the case where the first type of terminal device has the first switching capability and the second switching capability, and the second type of terminal device has the first switching capability, the second switching capability, and the third switching capability, if the network device needs to determine the switching capability currently used by the terminal device, the terminal device may report its own SSSG switching capability to the network device to explicitly determine the SSSG switching capability of the terminal device. The network device may directly receive the SSSG switching capability reported by the terminal device, where the SSSG switching capability includes any one of the first switching capability, the second switching capability, and the third switching capability.

[0144] The network device predefines a correspondence between multiple minimum switching delays under a first switching capability and the μ value of a terminal device, a correspondence between multiple minimum switching delays under a second switching capability and the μ value of a terminal device, and a correspondence between multiple minimum switching delays under a third switching capability and the μ value of a terminal device. Upon receiving the SSSG switching capability reported by the terminal device, the network device can determine the multiple minimum switching delays corresponding to the SSSG switching capability.

[0145] Among them, the SSSG switching capability reported by the terminal device is the current switching capability / processing capability of the terminal device. When the terminal device reports the switching capability, it can directly inform the network device of its own switching capability in an explicit manner.

[0146] For example, the RedCap UE in the first category of terminal devices can inform the network device of its own switching capability through the UE capability (terminal processing capability) signaling searchSpaceSwitchCapability2-R16 (search space set group switching capability 2-R16) or searchSpaceSetGrp-switchCap2-R17 (search space set group switching capability 2-R17), and the SSSG switching capability is indicated in the UE capability signaling.

[0147] For example, the eRedCap UE in the second type of terminal device can inform the network device of its own switching capability through RRC (Radio Resource Control) signaling searchSpaceSetGrp-switchCap0-R18 (search space set group switching capability 0-R18), and the SSSG switching capability is indicated in the RRC signaling.

[0148] Among them, after the network device receives the SSSG switching capability reported by the first type of terminal device, the network device will allocate the target switching delay for the first type of terminal device through the RRC signaling searchSpaceSwitchingDelay-R16 (search space switching delay-R16); after the network device receives the SSSG switching capability reported by the second type of terminal device, the network device will allocate the target switching delay for the second type of terminal device through the RRC signaling searchSpaceSwitchingDelay-R18 (search space switching delay-R18).

[0149] In step S502, a target switching delay is sent to the terminal device according to the minimum switching delay corresponding to the search space set group switching capability.

[0150] For an embodiment of this step, please refer to the above-mentioned step S102 and will not be described in detail here.

[0151] Through the above technical solution, the network device can determine the SSSG switching capability of the terminal device in an explicit manner, and thus send the target switching delay to the terminal device according to the minimum switching delay corresponding to the SSSG switching capability of the terminal device.

[0152] FIG6 is a flow chart showing a method for determining a handover delay according to an exemplary embodiment. The method for determining a handover delay is applied to a network device. As shown in FIG6 , the method for determining a handover delay includes the following steps.

[0153] In step S601, the search space set group switching capability of the terminal device is determined according to the PDSCH processing capability reported by the terminal device.

[0154] Among them, when the second type of terminal device has the first switching capability, the second switching capability and the third switching capability, if the network device needs to determine the switching capability currently used by the terminal device, the terminal device can report its own PDSCH processing capability to the network device, and the network device implicitly determines the SSSG switching capability of the terminal device based on the PDSCH processing capability.

[0155] The PDSCH processing capability includes a first PDSCH processing capability, a second PDSCH processing capability, and a third PDSCH processing capability. The first PDSCH processing capability is smaller than the second PDSCH processing capability, and the third PDSCH processing capability is smaller than the first PDSCH processing capability. The second PDSCH processing capability is the unrelaxed processing capability, the first PDSCH processing capability is the normal reduced processing capability, and the third PDSCH processing capability is the evolved reduced processing capability.

[0156] The terminal device may implicitly report its own switching capability to the network device. For example, the network device may receive the PDSCH processing capability reported by the terminal device and determine the SSSG switching capability of the terminal device based on the PDSCH processing capability, where the PDSCH processing capability includes any one of a first PDSCH processing capability, a second PDSCH processing capability, and a third PDSCH processing capability.

[0157] For example, when the network device receives the first PDSCH processing capability reported by the terminal device, it can implicitly determine that the SSSG switching capability of the terminal device is the first switching capability; when the network device receives the second PDSCH processing capability reported by the terminal device, it can implicitly determine that the SSSG switching capability of the terminal device is the second switching capability; when the network device receives the third PDSCH processing capability reported by the terminal device, it can implicitly determine that the SSSG switching capability of the terminal device is the third switching capability.

[0158] The first type of terminal equipment has a first PDSCH processing capability and a second PDSCH processing capability. For example, Normal UE and RedCap UE both have the first PDSCH processing capability and the second PDSCH processing capability. The second type of terminal equipment has a first PDSCH processing capability, a second PDSCH processing capability, and a third PDSCH processing capability. For example, eRedCap UE has the first PDSCH processing capability, a second PDSCH processing capability, and a third PDSCH processing capability.

[0159] In step S602, a target switching delay is sent to the terminal device according to the minimum switching delay corresponding to the search space set group switching capability.

[0160] For an embodiment of this step, please refer to the above-mentioned step S102 and will not be described in detail here.

[0161] Through the above technical solution, the terminal device reports its own PDSCH processing capability to the network device. The network device can implicitly determine the SSSG switching capability of the terminal device through the PDSCH processing capability, and thus send the target switching delay to the terminal device based on the minimum switching delay corresponding to the SSSG switching capability of the terminal device.

[0162] FIG7 is a flow chart showing a method for determining a handover delay according to an exemplary embodiment. The method for determining a handover delay is applied to a network device. As shown in FIG7 , the method for determining a handover delay includes the following steps.

[0163] In step S701, the search space set group switching capability of the terminal device is determined according to the terminal type reported by the terminal device.

[0164] The terminal types include the first type of terminal equipment non-eRedCap UE and the second type of terminal equipment eRedCap UE. The first type of terminal equipment includes Normal UE and RedCap UE

[0165] Among them, when the eRedCap UE in the second type of terminal device has the third processing capability, if the network device needs to determine the switching capability currently used by the terminal device, the terminal device can report its own terminal type to the network device, and the network device implicitly determines the SSSG switching capability of the terminal device based on the terminal type.

[0166] The terminal device may implicitly report its own switching capability to the network device. For example, the network device receives the terminal type reported by the terminal device and determines the search space set group switching capability of the terminal device based on the terminal type.

[0167] For example, when the network device receives a report from the terminal device indicating that the terminal type is eRedCap UE, it may implicitly determine that the SSSG switching capability of the terminal device is the third switching capability.

[0168] In step S702, a target switching delay is sent to the terminal device according to the minimum switching delay corresponding to the search space set group switching capability.

[0169] For an embodiment of this step, please refer to the above-mentioned step S102 and will not be described in detail here.

[0170] Through the above technical solution, the terminal device reports its own terminal type to the network device, and the network device can implicitly determine the SSSG switching capability of the terminal device through the terminal type, and thus send the target switching delay to the terminal device according to the minimum switching delay corresponding to the SSSG switching capability of the terminal device.

[0171] FIG8 is a flowchart of a method for determining a switching delay according to an exemplary embodiment. The method for determining a switching delay is applied to a network device. As shown in FIG8 , the method for determining a switching delay includes the following steps, wherein step S802 and step S803 may be executed simultaneously by the network device or separately.

[0172] In step S801, the search space set group switching capability of the terminal device is determined.

[0173] For the embodiment of this step, please refer to the above-mentioned step S101 and will not be described in detail here.

[0174] In step S802, RRC signaling is sent to the terminal device according to the minimum switching delay corresponding to the search space set group switching capability, and the RRC signaling carries the target switching delay.

[0175] Among them, the network device receives the switching capability reported by the terminal device through UE capability signaling, which is a type of RRC signaling; the network device determines the minimum switching delay based on the switching capability carried in the UE capability signaling, and then configures a target switching delay greater than or equal to the minimum switching delay in the RRC signaling, and sends the RRC signaling to the terminal device.

[0176] The terminal device switches the SSSG according to the duration indicated by the target switching delay.

[0177] In step S803, a downlink control signaling is sent to the terminal device, where the downlink control signaling is used to instruct the terminal device to switch to a target search space set group according to the downlink control signaling.

[0178] Among them, the network equipment will not only send RRC signaling, but also send DCI (downlink control signaling) signaling, instructing the terminal device to switch to the target SSSG with the target switching delay according to the target SSSG carried in the DCI signaling, and monitor the PDCCH with the target SSSG.

[0179] The target SSSG includes a sparse-cycle SSSG and a dense-cycle SSSG. The terminal device uses the sparse-cycle SSSG to monitor the PDCCH with a sparser cycle, and the terminal device uses the dense-cycle SSSG to monitor the PDCCH with a denser cycle.

[0180] The terminal device is located within the network coverage of the network device, so the network device knows whether the business of each terminal device is busy. When the business of the terminal device is busy, the SSSG with a dense cycle can be sent to the terminal device with busy business, so that the terminal device with busy business uses the SSSG to monitor the PDCCH with a more dense cycle; when the business of the terminal device is idle, the SSSG with a sparse cycle can be sent to the terminal device with sparse business, so that the terminal device with sparse business uses the SSSG to monitor the PDCCH with a more sparse cycle.

[0181] Among them, the network device can instruct the terminal device to perform SSSG switching in an explicit or implicit manner in the DCI signaling.

[0182] For example, the network device can directly carry the target SSSG in the DCI signaling to instruct the terminal device to switch to the target SSSG; the network device can also configure a timer in the DCI signaling, that is, use the configuration of one set of SSSG to monitor the PDCCH during the period when the timer is running, and use the configuration of another set of SSSG to monitor the PDCCH when the timer runs to another period.

[0183] Through the above technical solution, the network device can send RRC signaling and DCI signaling, so that the terminal device can switch to the target SSSG after the target switching delay indicated in the RRC signaling and the target SSSG in the DCI signaling.

[0184] FIG9 is a flow chart showing a method for determining a handover delay according to an exemplary embodiment. The method for determining a handover delay is applied to a terminal device. As shown in FIG9 , the method for determining a handover delay includes the following steps.

[0185] In step S901, a target switching delay of a switching search space set group sent by a network device is received, where the target switching delay is determined by the network device according to a minimum switching delay corresponding to a search space set group switching capability of the terminal device.

[0186] There are multiple minimum switching delays corresponding to the SSSG switching capability of the terminal device, and the minimum switching delays corresponding to the same SSSG switching capability are the same or different.

[0187] As shown in Table 2 above, the network device determines multiple minimum handover delays based on the terminal device's SSSG handover capability. From these minimum handover delays, the network device then determines a single minimum handover delay based on the terminal device's μ value. After determining the minimum handover delay, the network device sends a target handover delay, which is greater than or equal to the minimum handover delay and less than the maximum handover delay, to the terminal device. The terminal device then performs SSSG handover based on the target handover delay.

[0188] This step S901 can refer to the above-mentioned steps S101 and S102, and will not be repeated here.

[0189] Through the above technical solution, the network device can determine the SSSG switching capability of the terminal device, determine the minimum switching delay corresponding to the SSSG switching capability, and send the target switching delay to the terminal device based on the minimum switching delay. In this process, after the processing capability of the terminal device is reduced, the network device can also re-determine the processing capability of the terminal device, and send the target switching delay to the terminal device based on the minimum switching delay corresponding to the reduced processing capability of the terminal device, so that the terminal device with reduced processing capability can receive the corresponding target switching delay, avoiding the situation where the target switching delay received by the terminal device is not aligned with the target switching delay configured by the network device.

[0190] FIG10 is a flowchart of a method for determining a switching delay according to an exemplary embodiment. The method for determining a switching delay is applied to a terminal device. As shown in FIG10 , the method for determining a switching delay includes at least one of the following steps S110, S111, and S112.

[0191] In step S1001, a first target switching delay of a switching search space set group sent by the network device is received, where the first target switching delay is determined by the network device according to a minimum switching delay corresponding to a first switching capability of the terminal device.

[0192] Please refer to the above step S203 for this step, which will not be described again here.

[0193] In step S1002, a second target switching delay of the switching search space set group sent by the network device is received, where the second target switching delay is determined by the network device according to the minimum switching delay corresponding to the second switching capability of the terminal device.

[0194] Please refer to the above step S202 for this step, which will not be described again here.

[0195] In step S1003, a third target switching delay of the switching search space set group sent by the network device is received, where the third target switching delay is determined by the network device according to the minimum switching delay corresponding to the third switching capability of the terminal device;

[0196] The first target switching delay is greater than the second target switching delay, and the third target switching delay is greater than the first target switching delay.

[0197] Please refer to the above step S204 for this step, which will not be described again here.

[0198] Through the above technical solution, when the network device determines the first switching capability or the second switching capability of the first type of terminal device, it will send the first target switching delay or the second target switching delay to the first type of terminal device according to the minimum switching delay corresponding to the first switching capability or the second switching capability; when the network device determines the first switching capability or the second switching capability or the third switching capability of the second type of terminal device, it will send the first target switching delay or the second target switching delay or the third target switching delay to the second type of terminal device according to the minimum switching delay corresponding to the first switching capability or the second switching capability or the third switching capability, so that the first type of terminal device and the second type of terminal device with different processing capabilities can respectively obtain the corresponding target switching delay, thereby avoiding the situation where the target switching delay configured by the network device is not aligned with the switching delay required by the terminal device.

[0199] FIG11 is a flowchart of a method for determining a switching delay according to an exemplary embodiment. The method for determining a switching delay is applied to a terminal device. As shown in FIG11 , the method for determining a switching delay includes at least one of the following steps S1101, S1102, and S1103.

[0200] In step S1101, the search space set group switching capability of the terminal device is reported to the network device.

[0201] This step can refer to the above-mentioned step S501 and will not be described again here.

[0206] Through the above technical solution, the terminal device reports its own switching capability, PDSCH processing capability and at least one of the terminal type to the network device. The network device can determine the SSSG switching capability of the terminal device through at least one of the switching capability, PDSCH processing capability and terminal type of the terminal device, and thus send the target switching delay to the terminal device according to the minimum switching delay corresponding to the SSSG switching capability of the terminal device.

[0207] FIG12 is a flow chart showing a method for determining a handover delay according to an exemplary embodiment. The method for determining a handover delay is applied to a terminal device. As shown in FIG12 , the method for determining a handover delay includes the following steps.

[0208] In step S1201, an RRC signaling sent by the network device is received, where the RRC signaling carries the target handover delay.

[0209] This step can refer to the above-mentioned step S802 and will not be described again here.

[0210] In step S1202, a downlink control signaling sent by the network device is received.

[0211] This step can refer to the above-mentioned step S803 and will not be described again here.

[0212] In step S1203, switching to the target search space set group is performed according to the target search space set group indicated in the downlink control signaling.

[0213] This step can refer to the above-mentioned step S803 and will not be described again here.

[0214] Through the above technical solution, the network equipment can configure RRC signaling and DCI signaling so that the terminal device switches to the target SSSG after the target switching delay indicated in the RRC signaling and the target SSSG in the DCI signaling.

[0215] FIG13 shows a method for determining a handover delay according to an exemplary embodiment. The method is applied to a terminal device and a network device. The method includes the following steps:

[0216] In step S1301, the terminal device reports its search space set group switching capability to the network device.

[0217] Among them, the terminal device can report its own SSSG switching capability to the network device in at least one of the following ways: the terminal device directly reports its own SSSG switching capability to the network device, the terminal device reports its own PDSCH processing capability to the network device, and the terminal device reports its own terminal type to the network device.

[0220] Please refer to the above step S701 for the terminal device to report its own terminal type to the network device, and will not be repeated here.

[0221] In step S1302, the network device sends a target switching delay to the terminal device according to the minimum switching delay corresponding to the search space set group switching capability reported by the terminal device.

[0222] This step can refer to the above-mentioned step S102 and will not be described again here.

[0223] In step S1303, the terminal device switches to the target search space set group according to the target switching delay.

[0225] Through the above technical solution, the network device can determine the SSSG switching capability of the terminal device, and determine the minimum switching delay corresponding to the SSSG switching capability, and send the target switching delay to the terminal device based on the minimum switching delay, and the terminal device switches to the target SSSG with the target switching delay. In this process, after the processing capability of the terminal device is reduced, the network device can also re-determine the processing capability of the terminal device, and send the target switching delay to the terminal device based on the minimum switching delay corresponding to the reduced processing capability of the terminal device, so that the terminal device after the processing capability is reduced can receive the target switching delay with increased delay, thereby avoiding the situation where the target switching delay required by the terminal device is not aligned with the target switching delay configured by the network device.
