[0081] The execution entities involved in the embodiments of this disclosure include, but are not limited to, terminals (UE, User Equipment) in cellular mobile communication systems and base stations in cellular mobile communication systems.

[0082] Figure 2 This is a flowchart illustrating an application method for the downlink initial bandwidth portion according to an exemplary embodiment, such as... Figure 2 As shown, the reference signal availability indication method of this disclosure is applied to a network device, and the application method of the downlink initial bandwidth portion of this disclosure includes the following processing steps:

[0083] Step 201: Configure at least one type of downlink initial BWP resource for the paging user so that the paging user can use the BWP resource to listen for paging messages.

[0084] In this embodiment of the disclosure, network devices such as base stations need to determine the downlink initial bandwidth portion (BWP) resources of at least one type. The network devices can configure the corresponding downlink initial BWP resources for paging users. As one implementation, the base stations can configure the corresponding downlink initial BWP resources for paging users, or the core network can configure a strategy for configuring the corresponding downlink initial BWP resources for paging users, notify each base station of the relevant BWP resource configuration strategy, and then each base station configures the relevant BWP resources for paging users based on the configuration strategy.

[0085] In some exemplary embodiments, determining the at least one type of downlink initial bandwidth portion (BWP) resource includes: determining the at least one type of downlink initial bandwidth portion (BWP) resource according to the type of the paging user. As one implementation, determining the at least one type of downlink initial bandwidth portion (BWP) resource includes: determining the at least one type of downlink initial bandwidth portion (BWP) resource according to paging-specific service attributes.

[0086] In this embodiment of the disclosure, the network equipment includes base stations, relay stations, radio remote units, etc., and may also be core network side equipment.

[0087] In this embodiment of the disclosure, the at least one type includes a type determined according to the type of the paging user. The type of the paging user includes at least one of the following: a Redcap terminal type, or an enhanced Redcap terminal type.

[0088] As one implementation, in this embodiment of the disclosure, the at least one type includes a type determined according to paging-specific service attributes. The type determined according to paging-specific service attributes includes a type determined according to services belonging to a network slice. A network slice provides logically independent networks for related services such as autonomous driving and the Internet of Things to meet diverse service needs and support various application scenarios based on mobile networks.

[0089] In this embodiment of the disclosure, the BWP resource of the type determined according to the specific service attributes of paging includes N initial BWPs, where N is greater than or equal to 1. As an example, the N initial BWPs include: initial BWPs configured with the Master Information Block (MIB) and / or initial BWPs configured for specific types of users.

[0090] In this embodiment of the disclosure, each of the N initial BWPs is configured with a specific type of paging search space. As an example, the specific type of paging search space is configured as a Redcap terminal or an enhanced Redcap terminal. Alternatively, the specific type of paging search space is configured as a slice.

[0091] In this embodiment of the disclosure, based on the foregoing processing steps, the application method for the downlink initial bandwidth portion of this embodiment of the disclosure may further include:

[0092] The auxiliary information of the paging user is sent to the core network or other base stations, so that the other base stations use the at least one type of downlink BWP resources to paging the paging user.

[0093] As an example, sending the auxiliary information of the paging user to the core network includes: adding indication information of the paging user to the terminal radio paging information (UERadioPagingInfo) or the initial UE message, and sending it to the core network. Base stations or relay stations acting as access nodes notify the core network or other base stations of the auxiliary information of their paging users, facilitating subsequent downlink initiation of BWP paging of the user by the base station in which segment or category (there may be multiple) of the paging user. As one embodiment, the auxiliary information of the paging user indicates the type of the target user being paging, such as whether it is a Redcap user; or the slice supported by the target user being paging.

[0094] As an example, terminal radio capability information is carried in the RAN paging message; and / or, terminal radio capability information is carried in the CN paging message.

[0095] Specifically, the base station adds indication information of the paging target user to the UERadioPagingInfo and notifies the core network. For example, the base station adds information such as the user being a Redcap user and their slice to the UERadioPagingInfo.

[0096] The core network carries terminal radio capabilities, such as UE Radio Capability for Paging, in the paging message to assist the base station in initiating paging at the correct downlink initial BWP;

[0097] As an example, the base station carries terminal radio capabilities (such as UE Radio Capability for Paging) in RAN paging to assist the base station in initiating paging at the correct downlink initial BWP.

[0098] Figure 3 This is a flowchart illustrating an application method for the downlink initial bandwidth portion according to an exemplary embodiment, such as... Figure 3 As shown, the application method of the downlink initial bandwidth portion of this disclosure embodiment is applied to a terminal, and the application method of the downlink initial bandwidth portion of this disclosure embodiment includes the following processing steps:

[0099] Step 301: Select a target BWP based on predetermined rules to listen for paging messages.

[0100] In this embodiment of the disclosure, the predetermined rules include:

[0101] Perform a modulo operation on N target BWPs based on the terminal's identification information, and listen for paging messages on the corresponding target BWPs based on the modulo operation result; or

[0102] The target BWP is an initial BWP configured for a specific type of user, and it is configured with a paging search space, prioritizing or only listening for paging messages on individually configured initial BWPs (possibly more than one); or

[0103] Select a specific downlink initial BWP to listen for paging messages based on the slice supported by the terminal; or

[0104] Listen for paging messages on multiple downlink initial BWPs.

[0105] The following specific example further illustrates the essence of the technical solution of the embodiments of this disclosure.

[0106] Network devices, such as base stations or relay stations acting as access nodes, configure various types of downlink initial BWPs for paging users. These types can be categorized according to the type of the paging target user, such as a Redcap-type terminal or an enhanced Redcap-type terminal introduced in a later version. Alternatively, they can be categorized according to specific paging service attributes; for example, by belonging to a particular slice. In this embodiment, the network device can also be a related device on the core network side.

[0107] A specific type of downlink initial BWP is configured with N, where N is at least greater than 1.

[0108] The N downlink initial BWPs can contain initial BWPs configured in different ways. For example, they can include MIB-configured initial BWPs and / or initial BWPs configured for specific types of users.

[0109] As an example, N can be equal to 1, meaning that a specific type of user also listens for paging messages using the MIB-configured initial BWP.

[0110] Alternatively, N can be equal to 1, which is the initial BWP configured for a specific type of user. This downlink initial BWP includes coreset0. If a configured initial BWP includes coreset0, it can be used as a paging listener. In this case, if the number of users is small, there is no need to configure other downlink initial BWPs. coreset0 is a special type of coreset. The coreset is used for the transmission PDCCH of SIB1 scheduling, and its related configuration parameters are clearly defined in the relevant protocols, so they will not be repeated here.

[0111] As an example, N can be 2, meaning that if both the initial BWP configured by MIB and the initial BWP configured for a specific type of user are configured with a search space for paging of that specific user, then both can be used for paging of that specific user.

[0112] As an example, N can be 2, which means that two initial BWPs can be configured for a specific type of user and used for paging of that user. This is used in scenarios where the paging load is relatively large.

[0113] In this embodiment of the disclosure, the downlink initial BWP used by a specific type of user is configured with a search space for a specific type of paging. As an example, all N downlink initial BWPs include a search space for paging. If the network is configured with M initial BWPs, but only the N initial BWPs with configured search spaces are included in the calculation, where M is greater than or equal to N.

[0114] In this embodiment of the disclosure, as an example, the search space for a particular type of paging may be configured for Redcap or an enhanced Redcap.

[0115] In this embodiment of the disclosure, as an example, the search space for a particular type of paging may be configured for a certain slice.

[0116] In this embodiment of the disclosure, N downlink initial BWPs of a specific type may have the same or different parameters; they may have the same or different configurations, wherein different configurations include the case of no configuration and the case of configuration.

[0117] In this embodiment, the same configuration parameters can be reused in multiple downlink initial BWPs. As one example, some parameters can be reused from the MIB-configured initial BWP, while the corresponding fields may not exist in the initial BWP configured for a specific user. For instance, the Physical Control Channel (PCCH) parameters may not be configured in the initial BWP configured for a specific user, meaning that either the parameters in the MIB-configured initial BWP are reused or a new set of parameters is reconfigured.

[0118] In this embodiment of the disclosure, the same configuration can be reused in multiple downlink initial BWPs. This means that the terminal may need to hop to an initial BWP with that configuration in order to use it. For example, some downlink BWPs may not have this set of parameter configurations, and the terminal may need to hop to other downlink initial BWPs to use the parameters configured thereon.

[0119] The following examples illustrate this: N downlink initial BWPs can be configured with the same or different Broadcast Control Channel (BCCH) parameters: for example, the modificationPeriodCoeff parameter can be different, and for Redcap users, the modificationPeriodCoeff can be configured to be longer.

[0120] As an example, the downlink initial BWP can be configured with the same or different PCCH parameters: for example, the parameter defaultPagingCycle can be different, and for Redcap users, defaultPagingCycle can be configured to be longer.

[0121] As an example, the downlink initial BWP can be configured with the same or different Permanent Equipment Identifier (PEI) parameters. For instance, a PEI can be sent on each downlink initial BWP with the same configuration parameters.

[0122] As an example, the downlink initial BWP can be configured with the same or different Tracking Reference Signal (TRS) parameters. For instance, a TRS with identical configuration parameters can be sent on each downlink initial BWP.

[0123] As an example, the downlink initial BWP can be configured with different synchronization signals and PBCH blocks (SSBs). The SSB can be CD-SSB or NCD-SSB, or SSB can be configured or not. Furthermore, SSB parameters can be conditionally configured. For example, if the default PagingCycle is longer than a certain threshold, synchronization on this initial BWP can depend on the SSBs of other initial BWPs, such as the SSB configuration on the initial BWP configured in the MIB. In this case, the terminal needs to hop to the initial BWP configured in the MIB.

[0124] In this embodiment of the disclosure, based on the aforementioned initial BWP resource configuration on the network side, the terminal selects a target BWP for paging message listening based on predetermined rules. As an example, the predetermined rules can be based on the UE-ID modulo the total number of N downlink initial BWPs; listening is then performed on the corresponding downlink initial BWP according to the modulo index. For example, if the MIB-configured initial BWP and two downlink initial BWPs are configured for paging specific types of users, they are arranged according to 0, 1, and 2, and the modulo operation result can be used as an index to correspond to 0, 1, and 2, serving as the listening target.

[0125] In this embodiment of the disclosure, as an example, the predetermined rule may also be: if a paging search space is configured on the initial BWP configured for a specific type of user, then the specific user will listen on a single configured initial BWP (possibly more than one); here, regardless of whether the MIB-configured initial BWP is configured with a paging search space for a specific user.

[0126] In this embodiment of the disclosure, as an example, a predetermined rule may be used to select a specific downlink initial BWP according to the slice supported by the terminal.

[0127] In this embodiment of the disclosure, as an example, the terminal may listen to multiple downlink initial BWPs. Here, it can listen simultaneously or sequentially.

[0128] In this embodiment of the disclosure, network devices such as base stations add indication information of the paging user to the terminal radio paging information (UERadioPagingInfo) or the initial UE message and send it to the core network. The base station or relay station, acting as an access node, notifies the core network or other base stations of the auxiliary information of its paging user, facilitating subsequent downlink initial BWP paging of the user by the base station in which category (or possibly multiple categories).

[0129] As an example, terminal radio capability information is carried in the RAN paging message; and / or, terminal radio capability information is carried in the CN paging message.

[0130] Specifically, the base station adds indication information of the paging target user to the UERadioPagingInfo and notifies the core network. For example, the base station adds information such as the user being a Redcap user and their slice to the UERadioPagingInfo.

[0131] The core network carries terminal radio capabilities, such as UE Radio Capability for Paging, in the paging message to assist the base station in initiating paging at the correct downlink initial BWP;

[0132] As an example, the base station carries terminal radio capabilities (such as UE Radio Capability for Paging) in RAN paging to assist the base station in initiating paging at the correct downlink initial BWP.
