As shown in Fig. 2 , the reference signal availability indication method of this embodiment of the disclosure is applied to a network device, and the downlink initial bandwidth part of this embodiment of this disclosure The application method of the bandwidth part includes the following processing steps:

Step 201, configuring at least one type of downlink initial BWP resource for a paging user, so that the paging user uses the BWP resource to monitor paging messages.

In the embodiment of the present disclosure, a network device such as a base station needs to determine the at least one type of downlink initial bandwidth part BWP resource. The corresponding downlink initial BWP resource may be configured by the network device for the paging user. As an implementation, the base station configures the corresponding downlink initial BWP resource for the paging user, or the core network configures the corresponding downlink initial BWP resource strategy for the paging user, and notifies each base station of the relevant BWP resource configuration strategy , and each base station configures related BWP resources for the paging user based on the configuration strategy.

In some exemplary embodiments, the determining the at least one type of downlink initial bandwidth part BWP resource includes: determining at least one type of downlink initial bandwidth part BWP resource according to the type of the paging user. As an implementation manner, determining the at least one type of downlink initial bandwidth part BWP resource includes: determining the at least one type of downlink initial bandwidth part BWP resource according to a paging-specific service attribute.

In the embodiment of the present disclosure, the network device includes a base station, a relay station, a remote radio unit, etc., and may also be a core network side device.

In the embodiment of the present disclosure, the at least one type includes a type determined according to the type of the paging user. Wherein, the type of the paging user includes at least one of the following: type of Redcap terminal, type of enhanced Redcap terminal.

As an implementation manner, in this embodiment of the present disclosure, the at least one type includes a type determined according to a paging-specific service attribute. The type determined according to the attribute of the specific paging service includes the type determined according to the service belonging to the network slice (slice). Network slicing is to provide logically independent networks for related services such as autonomous driving and the Internet of Things to meet diverse business needs and support various application scenarios based on mobile networks.

In the embodiment of the present disclosure, the type of BWP resource determined according to the paging-specific service attribute includes N initial BWPs, where N is greater than or equal to 1. As an example, the N initial BWPs include: an initial BWP configured with a master system information block (Master Information Block, MIB) and/or an initial BWP configured for a specific type of user.

In the embodiment of the present disclosure, a specific type of paging search space is configured in each of the N initial BWPs. As an example, the search space of the specific type of paging is configured for a Redcap terminal or an enhanced Redcap terminal. Or, the search space of the specific type of paging is configured for a certain slice.

In the embodiment of the present disclosure, on the basis of the foregoing processing steps, the application method of the downlink initial bandwidth part in the embodiment of the present disclosure may further include:

As an example, the sending the auxiliary information of the paging user to the core network includes: adding the 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. The base station or relay station as an access node notifies the core network or other base stations of its auxiliary information for paging users, so as to facilitate which or which type (possibly multiple) downlink initial BWP paging users of subsequent base stations. As an embodiment, the auxiliary information of the paging user indicates the type of the paging target user, such as whether it is a Redcap user; or the slice supported by the paging target user.

The core network carries terminal wireless capabilities such as UE Radio Capability for Paging in the paging message, which is used to assist the base station to initiate paging at the correct downlink initial BWP;

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

Fig. 3 is a schematic flowchart of a method for applying an initial downlink bandwidth part according to an exemplary embodiment. The method for applying the initial bandwidth portion includes the following processing steps:

In step 301, a target BWP is selected based on a predetermined rule to monitor paging messages.

In the embodiment of the present disclosure, the predetermined rules include:

The target BWP is an initial BWP configured for a specific type of user, and a paging search space is configured, and the paging message is listened to first or only on a separately configured initial BWP (possibly more than one); or

Listen for paging messages at multiple downlink initial BWPs.

The essence of the technical solution of the embodiment of the present disclosure is further clarified through a specific example below.

A network device, such as a base station or a relay station serving as an access node, configures multiple types of downlink initial BWPs for paging users. The type may be classified according to the type of the paging target user, such as a Redcap type terminal or an enhanced Redcap type terminal introduced in a subsequent version. Alternatively, the type may be a type according to a specific paging service attribute; for example, a type classified according to belonging to a certain slice. In the embodiments of the present disclosure, the network device may also be a related device on the core network side.

There are N number of downlink initial BWP configurations of a specific type, where N is at least greater than 1.

The N downlink initial BWPs may include initial BWPs configured in different configuration modes. For example, including MIB-configured initial BWPs and/or initial BWPs configured for specific types of users.

As an example, N may be equal to 1, that is, a specific type of user also uses the MIB-configured initial BWP to monitor paging messages.

Alternatively, N can be equal to 1, that is, the initial BWP configured for a specific type of user, and the downlink initial BWP includes coreset0. If a configured initial BWP includes coreset0, it can be used as a paging monitor. At this time, if the number of users is small, there is no need to additionally configure other downlink initial BWPs. coreset0 is a special type of coreset. The coreset is the coreset used to transmit the PDCCH scheduled by the SIB1, and its related configuration parameters are clearly defined in related protocols, and will not be repeated here.

As an example, N can be 2, that is, if the MIB-configured initial BWP and the initial BWP configured for a specific type of user are also configured with a search space for paging for a specific user; then both can be used as paging for a specific user .

As an example, N may be 2, that is, two initial BWPs configured for a specific type of user can be used as paging for a specific user, and this case is used in a scenario where the paging load is relatively large.

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

In the embodiment of the present disclosure, as an example, the search space of a specific type of paging may be configured for Redcap or enhanced Redcap.

In the embodiments of the present disclosure, as an example, a specific type of paging search space may be configured for a certain slice.

In the embodiment of the present disclosure, the N downlink initial BWPs of a specific type may have the same parameters or different parameters; they may have the same configuration or different configurations, wherein the different configurations include unconfigured and configured situations.

In the embodiment of the present disclosure, the same configuration parameter can be multiplexed in multiple downlink initial BWPs. As an example, some parameters may reuse parameters in the MIB-configured initial BWP, and corresponding fields may not exist in the initial BWP configured for a specific user. For example, physical control channel (Physical Control CHannel, PCCH) parameters may not be configured for the initial BWP configured for a specific user, which means reusing the parameters in the MIB-configured initial BWP or reconfiguring a set of new parameters.

In the embodiment of the present disclosure, the same configuration can be multiplexed in multiple downlink initial BWPs. This means that the terminal may need to frequency hop to the initial BWP with this configuration before it can be used. For example, some downlink BWPs do not have this set of parameter configurations, and need to hop to other downlink initial BWPs to use the parameters configured there.

The relevant examples are listed below for illustration: N downlink initial BWPs can be configured with the same or different Broadcast Control Channel (BCCH) parameters: for example, the parameter modificationPeriodCoeff can be different, and the modificationPeriodCoeff can be configured longer for Redcap users.

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 the defaultPagingCycle can be configured longer for Redcap users.

As an example, the downlink initial BWP may be configured with the same or different permanent equipment identifier (Permanent Equipment Identifier, PEI) parameters. For example, the PEI can be sent on each downlink initial BWP, and its configuration parameters are the same.

As an example, the downlink initial BWP may be configured with the same or different tracking reference signal (Tracking Reference Signal, TRS) parameters. For example, a TRS may be sent on each downlink initial BWP, and its configuration parameters are the same.

As an example, the downlink initial BWP may be configured with different synchronization signals and PBCH blocks (Synchronization Signal and PBCH block, SSB). The SSB here can be CD-SSB or NCD-SSB, or, SSB is configured or not configured. Furthermore, SSB parameters can also be configured conditionally. For example, if the defaultPagingCycle is longer than a certain threshold, the synchronization on the initial BWP can depend on the SSB of other initial BWPs, such as the SSB configuration on the initial BWP configured by MIB for synchronization. At this time, the terminal needs to frequency hop to the initial BWP configured in the MIB.

In the embodiments of the present disclosure, based on the aforementioned initial BWP resource configuration on the network side, the terminal selects a target BWP based on a predetermined rule to monitor paging messages. As an example, the predetermined rule can take the modulus of the total number of N downlink initial BWPs according to the UE-ID; monitor the corresponding downlink initial BWP according to the index of the modulus; for example, MIB-configured initial BWP and specific type of user Two downlink initial BWPs are configured for paging, and they are arranged according to 0, 1, and 2, and the result of the modulo operation can be used as an index to correspond to 0, 1, and 2 as the monitoring object.

In this embodiment of the present 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 has priority or only listens on the separately configured initial BWP ( may be greater than 1); here, regardless of whether the MIB-configured initial BWP configures a paging search space for a specific user.

In the embodiments of the present disclosure, as an example, the predetermined rule may select a specific downlink initial BWP according to slices supported by the terminal.

In the embodiments of the present disclosure, as an example, the terminal may monitor multiple downlink initial BWPs. Here, you can monitor at the same time or sequentially.

In the embodiment of the present disclosure, a network device such as a base station adds the indication information of the paging user to the terminal radio paging information (UERadioPagingInfo) or the initial UE message, and sends it to the core network. The base station or relay station as an access node notifies the core network or other base stations of its auxiliary information for paging users, so as to facilitate which or which type (possibly multiple) downlink initial BWP paging users of subsequent base stations.
