[0002] With the development of wireless communication networks, Reduced Capability (RedCap) terminals have been introduced.

Figure 1 As shown, the wireless communication system is a communication system based on mobile communication technology. The wireless communication system may include: several user equipment 110 and several base stations 120.

[0081] User equipment 110 can be a device that provides voice and / or data connectivity to a user. User equipment 110 can communicate with one or more core networks via a Radio Access Network (RAN). User equipment 110 can be an Internet of Things (IoT) user equipment, such as sensor devices, mobile phones, and computers with IoT user equipment capabilities. For example, it can be a fixed, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted device.

Alternatively, user equipment 110 can also be a device from an unmanned aerial vehicle (UAV). Alternatively, user equipment 110 can also be a vehicle-mounted device, such as a vehicle computer with wireless communication capabilities, or a wireless user equipment connected to an external vehicle computer. Alternatively, user equipment 110 can also be a roadside device, such as a street light, traffic light, or other roadside device with wireless communication capabilities.

[0082] Base station 120 can be a network-side device in a wireless communication system. This wireless communication system can be a fourth-generation mobile communication (4G) system, also known as a Long Term Evolution (LTE) system; or it can be a 5G system, also known as a New Radio (NR) system; or it can be the next generation after 5G. In this case, the access network in the 5G system can be called NG-RAN (New Generation-Radio Access Network).

[0083] The base station 120 can be an evolved NB (eNB) used in a 4G system. Alternatively, the base station 120 can also be a gNB (gNB) using a centralized-distributed architecture in a 5G system. When the base station 120 adopts a centralized-distributed architecture, it typically includes a central unit (CU) and at least two distributed units (DUs). The central unit is equipped with a protocol stack of the Packet Data Convergence Protocol (PDCP) layer, the Radio Link Control (RLC) layer, and the Media Access Control (MAC) layer; the distributed units are equipped with a physical (PHY) layer protocol stack. This disclosure does not limit the specific implementation of the base station 120.

Network management device 130 can be a core network device in a wireless communication system, such as a Mobility Management Entity (MME) in an Evolved Packet Core (EPC). Alternatively, it can be other core network devices, such as a Serving Gateway (SGW), a Public Data Network Gateway (PGW), a Policy and Charging Rules Function (PCRF), or a Home Subscriber Server (HSS). The implementation of network management device 130 is not limited in this embodiment.

[0089] To facilitate understanding by those skilled in the art, this disclosure provides multiple embodiments to clearly illustrate the technical solutions of the embodiments of this disclosure. Of course, those skilled in the art will understand that the multiple embodiments provided in this disclosure can be executed individually, or in combination with the methods of other embodiments in this disclosure, or individually or in combination with some methods in other related technologies; this disclosure does not limit these aspects.

[0090] To better understand the technical solutions described in any embodiment of this disclosure, the application scenarios in the related technologies are first explained:

[0091] Since NR is designed for terminals with high speed and low latency, the design may not meet the requirements of RedCap terminals. Therefore, the NR system needs to be modified to meet the requirements of RedCap terminals.

[0092] In some embodiments, to meet requirements such as low cost and low complexity, the frequency range (RF) bandwidth of RedCap can be limited. For example, the RF bandwidth can be limited to 5 MHz or 10 MHz, or the size of the RedCap buffer can be limited, thereby limiting the size of each received transmission block. For power-saving features, the communication process can be simplified, reducing the number of times RedCap users need to detect the downlink control channel.

[0093] MBS is a multicast and broadcast service in NR systems. During standardization, the CFR (Content Flow Chart) was defined to facilitate the transmission of MBS-related PDCCH and / or PDSCH. The configuration and transmission of MBS-related PDCCH and / or PDSCH are based on the CFR.

[0094] In one embodiment, for a terminal in Radio Resource Control (RRC) disconnected state, the terminal uses the frequency resources corresponding to resource set CORESET#0 as the CFR. The reason for using CORESET#0 as the basis for CFR configuration is that the terminal resides on the BWP corresponding to CORESET#0 when in RRC disconnected state. Here, RRC disconnected state includes RRC idle state and RRC inactive state.

[0095] In one embodiment, considering factors such as terminal bandwidth limitations and Time Division Duplexing (TDD), an initial UL BWP and / or DL ​​BWP will be defined for the RedCap terminal. In one embodiment, RedCap can reside on this initial DL BWP. That is, the terminal can receive paging messages on this BWP.

[0096] In one embodiment, please refer to Table 1, which illustrates a resource mapping diagram. For RedCap terminals, when the RedCap terminal is in an RRC disconnected state, the initial DL BWP detected by the RedCap terminal may not include the CFR of the MBS. For example, Cases 3 to 6 in Table 1.

[0098]

[0099]

[0100] like Figure 2 As shown, this embodiment provides a resource determination method, wherein the method is executed by a network device, and the method includes:

[0101] Step 21: Determine the reserved resources based on the reservation information;

[0102] The predetermined information indicates that: multicast and broadcast services (MBS) will be provided to Type 1 terminals or MBS services will not be provided to Type 1 terminals; the predetermined resources include at least one of the following: common frequency resources (CFR) and the initial downlink bandwidth portion (DL BWP) for use by Type 1 terminals.

[0103] Here, the terminals involved in this disclosure may be, but are not limited to, mobile phones, wearable devices, vehicle terminals, roadside units (RSUs), smart home terminals, industrial sensing devices, and / or medical devices. In this disclosure, the first type of terminal may be a RedCap terminal (RedCap UE), such as an electricity meter or water meter. The second type of terminal in this disclosure may be a non-RedCap terminal (Non-RedCap UE). A non-RedCap terminal can be any terminal other than a RedCap terminal. The capabilities of the first type of terminal and the second type of terminal differ, which may include differences in supported bandwidth, latency, and power. It should be noted that the first type of terminal is a reduced version of the capabilities of the second type of terminal. In the embodiments of this disclosure, the terminal may be in an RRC non-connected state. This RRC non-connected state includes an RRC idle state and an RRC inactive state. The terminal being in an RRC non-connected state can mean that the terminal is in either an RRC idle state or an RRC inactive state.

[0104] The network devices involved in this disclosure can be access devices for terminals accessing a network. Here, the network devices can be various types of base stations, such as base stations for third-generation (3G) networks, fourth-generation (4G) networks, fifth-generation (5G) networks, or other evolved base stations. It should be noted that the network devices in this disclosure are not limited to base stations in the access network, but can also be communication nodes in the core network, without limitation. For example, the determination and / or configuration operations in this disclosure can also be performed by network devices in the core network.

[0105] In one embodiment, the network device obtains reservation information, which may be determined based on the subscription information of a first type of terminal; in response to the reservation information instructing the first type of terminal to provide MBS, the device determines reservation resources, wherein the reservation resources include CFR and an initial DL BWP for use by the first type of terminal, the CFR being included within the initial DL BWP and / or the initial DL BWP and CFR being within the bandwidth supported by the first type of terminal. It should be noted that, in this disclosure, determining reservation resources may include configuring reservation resources, or determining reservation resources may simply be configuring reservation resources.

[0106] Here, the CFR allows Type 1 terminals to configure and transmit MBS-related PDCCH and / or PDSCH on the CFR. The initial DL BWP allows Type 1 terminals to listen for paging messages on the initial DL BWP.

[0107] In this disclosure, bandwidth may refer to bandwidth range, and is not limited here.

[0108] It should be noted that if a CFR is included in the initial DL BWP and the bandwidth range of the initial DL BWP is within the bandwidth range supported by the terminal, then the CFR can be determined to be within the bandwidth range supported by the terminal. Alternatively, if the CFR is not included in the initial DL BWP, then the CFR may or may not be within the bandwidth range supported by the terminal. Furthermore, if the CFR is not included in the initial DL BWP but the initial DL BWP is within the bandwidth range supported by the terminal, then the CFR may or may not be within the bandwidth range supported by the terminal. The initial DL BWP and CFR being within the bandwidth supported by the terminal can mean that the frequency ranges of both the initial DL BWP and CFR are not greater than the bandwidth range supported by the terminal; that is, the frequency range of the initial DL BWP is not greater than the bandwidth range supported by the terminal, and the frequency range of the CFR is not greater than the bandwidth range supported by the terminal. For example, the frequency range corresponding to the CFR is a to b, and the frequency range corresponding to the initial DL BWP is c to d, where a < b < c < d, and the bandwidth supported by the terminal is X. If the difference between b and a is less than X, then the CFR is within the bandwidth supported by the terminal; if the difference between b and a is greater than X, then the CFR is not within the bandwidth supported by the terminal. Similarly, if the difference between d and c is less than X, then the initial DL BWP is within the bandwidth supported by the terminal; if the difference between d and c is greater than X, then the initial DL BWP is not within the bandwidth supported by the terminal. If the difference between d and a is less than X, then both the CFR and the initial DL BWP are within the terminal's supported bandwidth. The terminal here can be a first-type terminal, for example, a RedCap terminal.

[0109] In one embodiment, the network device may configure the location of the time-frequency domain resources of the CFR to be within the location of the time-frequency domain resources of the initial DL BWP, wherein the time-frequency domain resources include time-domain and / or frequency-domain resources.

[0110] For example, the location corresponding to the time-frequency domain resources of the CFR is the first resource block, and the location corresponding to the time-frequency domain resources of the initial DL BWP is the second resource block, wherein the second resource block covers the first resource block. Here, the second resource block may cover the first resource block in the time domain and / or frequency domain, which is not limited in this disclosure. It should be noted that if the location of the time-frequency domain resources of the CFR is within the location of the time-frequency domain resources of the initial DL BWP, the second resource block may completely cover the first resource block. Here, the first resource block may be a sub-resource block of the second resource block, wherein the second resource block may contain multiple sub-resource blocks.

[0111] In one embodiment, the network device can be configured such that the sum of the bandwidth range of the CFR and the initial DL BWP is within the bandwidth range supported by the first type of terminal. Here, the first type of terminal can be a RedCap terminal.

[0112] For example, the frequency range of CFR corresponds to a first bandwidth, and the frequency range of the initial DL BWP corresponds to a second bandwidth, wherein both the first bandwidth and the second bandwidth are less than or equal to the bandwidth supported by the first type of terminal. In one embodiment, the first bandwidth may be less than the second bandwidth. Here, the first type of terminal may be a RedCap terminal; the initial DL BWP may be sent to the first type of terminal via a Master Information Block (MIB).

[0113] It should be noted that in the relevant technologies, the bandwidth corresponding to the frequency range of the initial DL BWP sent through the MIB can only be less than the bandwidth supported by the terminal, but the bandwidth corresponding to the frequency range of the initial DL BWP sent through the System Information Block (SIB) can be greater than the bandwidth supported by the terminal or less than or equal to the bandwidth supported by the terminal.

[0114] In one embodiment, the network device determines whether to configure or not configure predetermined resources based on predetermined information; wherein the predetermined information indicates whether to provide MBS to the first type of terminal or not to provide MBS to the first type of terminal.

[0115] In one embodiment, in response to providing MBS to a first type of terminal, the initial DL BWP is configured to include CFR and / or the initial DL BWP and CFR are configured within the bandwidth supported by the first type of terminal. Alternatively, in response to determining that MBS is not provided to the first type of terminal, the network device does not configure CFR, or the initial DL BWP configured by the network device does not include CFR, or the sum of the frequency domain resource ranges of the initial DL BWP and CFR configured by the network device is greater than the bandwidth range supported by the first type of terminal.

[0116] In one embodiment, the initial DL BWP and CFR have been configured before performing step 21, wherein the configured CFR is a CFR configured for non-RedCap terminals. In one embodiment, in response to the time-frequency domain position of the configured CFR not being included in the time-frequency domain position of the initial DL BWP, a CFR for use by the first type of terminal is configured; or, in response to the time-frequency domain position of the configured CFR being included in the time-frequency domain position of the initial DL BWP, a CFR for use by the first type of terminal is not configured.

[0117] For example, if the CFR already configured for a non-RedCap terminal is CORESET#0, and the initial DL BWP that has already been configured is also CORESET#0, then the position of the time-frequency domain of the configured CFR is included within the position of the time-frequency domain of the initial DL BWP. Alternatively, if the CFR already configured for a non-RedCap terminal is SIB1-configured, and the initial DL BWP that has already been configured is CORESET#0, then the position of the time-frequency domain of the configured CFR is not included within the position of the time-frequency domain of the initial DL BWP.

[0118] In one embodiment, a predetermined resource is configured; configuration information instructing the first type of terminal to perform processing operations on the MBS based on the configuration information is sent. For example, in response to the initial DL BWP containing a CFR, the first type of terminal can be instructed to listen to the MBS; or, in response to the initial DL BWP not containing a CFR, the first type of terminal can be instructed not to listen to the MBS; or, in response to the sum of the frequency domain resource ranges of the initial DL BWP and CFR being less than or equal to the bandwidth range supported by the first type of terminal, the first type of terminal can be instructed to listen to the MBS; or, in response to the sum of the frequency domain resource ranges of the initial DL BWP and CFR being greater than the bandwidth range supported by the first type of terminal, the first type of terminal can be instructed not to listen to the MBS. Here, the first type of terminal may be a terminal in a Radio Resource Control (RRC) disconnected state.

[0119] In this embodiment of the disclosure, predetermined resources are determined based on predetermined information; wherein, the predetermined information indicates whether to provide multicast and broadcast services (MBS) to the first type of terminal or not to provide MBS services to the first type of terminal; the predetermined resources include at least one of the following: common frequency resources (CFR) and / or the initial downlink bandwidth portion (DL BWP) for use by the first type of terminal. Thus, since the predetermined resources are determined based on predetermined information, the predetermined resources can be adapted to whether the network device provides MBS to the first type of terminal. Compared to randomly configuring predetermined resources, the common frequency resources (CFR) and / or the initial DL BWP for use by the first type of terminal can be configured for the first type of terminal, thereby achieving resource sharing to improve network resource utilization and / or reducing power consumption caused by frequent resource switching, and improving the terminal's battery life.

[0120] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0121] like Figure 3As shown, this embodiment provides a resource determination method, wherein the method is executed by a network device, and the method includes:

[0122] Step 31: In response to providing MBS to the first type of terminal, determine that CFR is included in the initial DL BWP.

[0123] Here, the first type of terminal is the Red Cap terminal. The initial DL BWP is the initial DLBWP for use by the first type of terminal.

[0124] In this disclosure, determining that a CFR is included within an initial DL BWP may include configuring the CFR to be included within the initial DL BWP.

[0125] It should be noted that if it is determined that MBS will not be provided to Type 1 terminals, the network device will not be configured with CFR, or the initial DL BWP configuration may not include CFR.

[0126] In one embodiment, in response to providing MBS to a first type of terminal, predetermined resources are configured, wherein the predetermined resources include at least one of the following: CFR and an initial DL BWP for use by the first type of terminal; the CFR is included in the initial DL BWP; configuration information indicating the predetermined resources is sent to the first type of terminal. The configuration information may instruct the first type of terminal to perform processing operations for MBS based on the configuration information. Exemplarily, in response to the initial DL BWP containing CFR, the first type of terminal is instructed to listen to MBS; or, in response to the initial DL BWP not containing CFR, the first type of terminal is instructed not to listen to MBS.

[0127] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0128] like Figure 4 As shown, this embodiment provides a resource determination method, wherein the method is executed by a network device, and the method includes:

[0129] Step 41: In response to providing MBS to the first type of terminal, determine that the sum of the frequency domain resource ranges of the initial DL BWP and CFR is less than or equal to the bandwidth range supported by the first type of terminal.

[0130] Here, the first type of terminal is the Red Cap terminal. The initial DL BWP is the initial DLBWP for use by the first type of terminal.

[0131] In this disclosure, if the sum of the frequency domain resource ranges of the initial DL BWP and CFR is less than or equal to the bandwidth range supported by the first type of terminal (that is, the sum of the frequency domain resource ranges of the DL BWP and CFR is within the bandwidth supported by the first type of terminal), then configuring the initial DL BWP and CFR to be within the bandwidth supported by the first type of terminal may be included.

[0132] It should be noted that if it is determined that MBS will not be provided to the first type of terminal, the network device will not be configured with CFR, or the sum of the frequency domain resource ranges of the initial DL BWP and CFR configured will be greater than the bandwidth range supported by the first type of terminal (that is, the sum of the frequency domain resource ranges of the initial DL BWP and CFR configured will not be within the bandwidth supported by the first type of terminal).

[0133] In one embodiment, in response to determining that MBS is to be provided to a first type of terminal, predetermined resources are configured, wherein the predetermined resources include at least one of the following: a Frequency Frame Rate (CFR) and an initial DL BWP for use by the first type of terminal; the initial DL BWP and CFR are within the bandwidth supported by the first type of terminal; and configuration information indicating the predetermined resources is sent to the first type of terminal. The configuration information may instruct the first type of terminal to perform processing operations for MBS based on the configuration information. For example, in response to the sum of the frequency domain resource ranges of the initial DL BWP and CFR being within the terminal bandwidth supported by the terminal, the first type of terminal is instructed to listen for MBS; or, in response to the sum of the frequency domain resource ranges of the initial DL BWP and CFR not being within the terminal bandwidth supported by the terminal, the first type of terminal is instructed not to listen for MBS.

[0134] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0135] like Figure 5 As shown in the embodiments of this disclosure, a resource determination method is provided, wherein the method is executed by a network device, and the method includes:

[0136] Step 51: Based on the time-frequency domain positional relationship between the initial DL BWP and the CFR used by the second type of terminal, determine the configuration operation for the CFR used by the first type of terminal;

[0137] The time-frequency domain location includes time domain and / or frequency domain location; the capabilities of the second type of terminal are different from those of the first type of terminal; the CFR used by the first type of terminal is included in the initial DL BWP, or the CFR used by the first type of terminal and the initial DL BWP are within the terminal bandwidth supported by the terminal.

[0138] Here, the first type of terminal is a RedCap terminal, and the second type of terminal is a non-RedCap terminal.

[0139] Here, the CFR for use by the second type of terminal can be the resources applied to MBS configured for non-RedCap terminals.

[0140] Here, the initial DL BWP can be the resources configured for the RedCap endpoint.

[0141] In one embodiment, before performing step 21, the network device configures an initial DL BWP for RedCap terminals and a CFR for use by a second type of terminal. Based on the time-frequency domain positional relationship between the configured initial DL BWP for RedCap terminals and the CFR for use by the second type of terminal, a configuration operation for the CFR for use by a first type of terminal is determined. Here, the configuration operation includes configuring the CFR for use by the first type of terminal or not configuring the CFR for use by the first type of terminal.

[0142] In one embodiment, if the time-frequency domain location of the CFR used by the second type of terminal is not included in the time-frequency domain location of the initial DLBWP, the network device configures the CFR used by the first type of terminal; or, if the time-frequency domain location of the CFR used by the second type of terminal is included in the time-frequency domain location of the initial DLBWP, the network device no longer configures the CFR used by the first type of terminal.

[0143] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0144] like Figure 6 As shown in the embodiments of this disclosure, a resource determination method is provided, wherein the method is executed by a network device, and the method includes:

[0145] Step 61: In response to the fact that the CFR for use by the second type of terminal is not included in the initial DL BWP, configure the CFR for use by the first type of terminal.

[0146] Here, the first type of terminal is a RedCap terminal, and the second type of terminal is a non-RedCap terminal. The initial DL BWP can be the initial DL BWP resource configured for a RedCap terminal.

[0147] In one embodiment, the CFR for use by the first type of terminal is included within the initial DL BWP, or the CFR for use by the first type of terminal and the initial DL BWP are within the terminal bandwidth supported by the terminal.

[0148] In one embodiment, the location corresponding to the time-frequency domain resources of the CFR used by the second type of terminal is the first resource block, and the location corresponding to the time-frequency domain resources of the initial DL BWP is the second resource block. If the second resource block does not cover the first resource block, then the time-frequency domain location of the CFR used by the second type of terminal is not included in the time-frequency domain location of the initial DL BWP. Here, it may be that the second resource block does not cover the first resource block in the time domain and / or frequency domain, which is not limited in this disclosure. Here, the time-frequency domain location of the CFR used by the second type of terminal not being included in the time-frequency domain location of the initial DL BWP may be that the second resource block does not completely cover the first resource block.

[0149] In one embodiment, in response to the time-frequency domain location of the CFR used by the second type of terminal not being included in the time-frequency domain location of the initial DL BWP, a CFR used by the first type of terminal is configured. Configuration information is sent to the first type of terminal, the configuration information including the CFR used by the first type of terminal; the configuration information is used to instruct the first type of terminal to perform processing operations for MBS based on the configuration information. Exemplarily, in response to the initial DL BWP containing a CFR, the first type of terminal is instructed to monitor MBS; or, in response to the initial DL BWP not containing a CFR, the first type of terminal is instructed not to monitor MBS; or, in response to the sum of the frequency domain resource ranges of the initial DL BWP and CFR being within the terminal bandwidth supported by the terminal, the first type of terminal is instructed to monitor MBS; or, in response to the sum of the frequency domain resource ranges of the initial DL BWP and CFR not being within the terminal bandwidth supported by the terminal, the first type of terminal is instructed not to monitor MBS.

[0150] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0151] like Figure 7 As shown in the embodiments of this disclosure, a resource determination method is provided, wherein the method is executed by a network device, and the method includes:

[0152] Step 71: In response to the fact that the CFR for the second type of terminal is included in the initial DL BWP, the CFR for the first type of terminal is not configured.

[0153] Here, the first type of terminal is a RedCap terminal, and the second type of terminal is a non-RedCap terminal. The initial DL BWP can be configured with resources for RedCap terminals.

[0154] In one embodiment, the CFR for use by the first type of terminal is included within the initial DL BWP, or the CFR for use by the first type of terminal and the initial DL BWP are within the terminal bandwidth supported by the terminal.

[0155] In one embodiment, the location corresponding to the time-frequency domain resources of the CFR used by the second type of terminal is a first resource block, and the location corresponding to the time-frequency domain resources of the initial DL BWP is a second resource block. If the second resource block covers the first resource block, then the time-frequency domain location of the CFR used by the second type of terminal is included within the time-frequency domain location of the initial DL BWP. Here, the second resource block may cover the first resource block in the time domain and / or frequency domain, which is not limited in this disclosure. Here, the inclusion of the time-frequency domain location of the CFR used by the second type of terminal within the time-frequency domain location of the initial DL BWP may mean that the second resource block completely covers the first resource block.

[0156] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0157] like Figure 8 As shown in the embodiments of this disclosure, a method for monitoring MBS is provided, wherein the method is executed by a first type of terminal, and the method includes:

[0158] Step 81: Based on the configuration results of the predetermined resources, perform monitoring and processing operations for MBS;

[0159] The reserved resources include at least one of the following: CFR and initial DL BWP for use by Type 1 terminals; the processing operations include: monitoring MBS or not monitoring MBS.

[0160] Here, the terminals involved in this disclosure may be, but are not limited to, mobile phones, wearable devices, vehicle terminals, roadside units (RSUs), smart home terminals, industrial sensing devices, and / or medical devices. In this disclosure, the first type of terminal may be a RedCap terminal, such as an electricity meter or water meter. The second type of terminal in this disclosure may be a non-RedCap terminal, which can be any terminal other than a RedCap terminal. The capabilities of the first type of terminal and the second type of terminal differ, which may include differences in supported bandwidth, latency, and power, etc. It should be noted that the first type of terminal is a terminal with reduced capabilities from the second type of terminal. In the embodiments of this disclosure, the terminal may be a terminal in an RRC non-connected state. This RRC non-connected state includes an RRC idle state and an RRC inactive state. The terminal being in an RRC non-connected state can mean that the terminal is in an RRC idle state or an RRC inactive state.

[0161] The network devices involved in this disclosure can be access devices for terminals accessing a network. Here, the network devices can be various types of base stations, such as base stations for third-generation (3G) networks, fourth-generation (4G) networks, fifth-generation (5G) networks, or other evolved base stations. It should be noted that the network devices in this disclosure are not limited to base stations in the access network; they can also be communication nodes in the core network, without limitation. For example, the configuration operations in this disclosure can also be performed by network devices in the core network.

[0162] In one embodiment, a first-type terminal receives configuration information sent by a network device, wherein the configuration information indicates a predetermined resource.

[0163] In one embodiment, the configuration information is determined by the network device based on predetermined information; wherein, the predetermined information may be determined based on the subscription information of the first type of terminal; wherein, the predetermined resources include a CFR and an initial DL BWP for use by the first type of terminal, the CFR being included within the initial DL BWP and / or the initial DL BWP and CFR being within the bandwidth supported by the first type of terminal. It should be noted that, in this disclosure, determining the predetermined resources may include: configuring the predetermined resources, or determining the predetermined resources may simply be configuring the predetermined resources.

[0164] Here, the configuration and transmission of PDCCH and / or PDSCH related to MBS are based on this CFR. Type 1 terminals can listen for paging messages on the initial DL BWP.

[0165] It should be noted that if a CFR is included in the initial DL BWP and the bandwidth range of the initial DL BWP is within the bandwidth supported by the terminal, then the CFR can be determined to be within the bandwidth supported by the terminal. Alternatively, if the CFR is not included in the initial DL BWP, then the CFR may or may not be within the bandwidth supported by the terminal. Furthermore, if the CFR is not included in the initial DL BWP but the initial DL BWP is within the bandwidth supported by the terminal, then the CFR may or may not be within the bandwidth supported by the terminal. The initial DL BWP and CFR being within the bandwidth supported by the terminal can mean that the frequency ranges of both the initial DL BWP and CFR are not greater than the bandwidth supported by the terminal; that is, the frequency range of the initial DL BWP is not greater than the bandwidth supported by the terminal, and the frequency range of the CFR is not greater than the bandwidth supported by the terminal. For example, the frequency range corresponding to the CFR is a to b, and the frequency range corresponding to the initial DL BWP is c to d, where a < b < c < d, and the bandwidth supported by the terminal is X. If the difference between b and a is less than X, then the CFR is within the bandwidth supported by the terminal; if the difference between b and a is greater than X, then the CFR is not within the bandwidth supported by the terminal. Similarly, if the difference between d and c is less than X, then the initial DL BWP is within the bandwidth supported by the terminal; if the difference between d and c is greater than X, then the initial DL BWP is not within the bandwidth supported by the terminal. If the difference between d and a is less than X, then both the CFR and the initial DL BWP are within the terminal's supported bandwidth. The terminal here can be a first-type terminal, for example, a RedCap terminal.

[0166] In one embodiment, the location of the time-frequency domain resources of the CFR is within the location of the time-frequency domain resources of the initial DL BWP, wherein the time-frequency domain resources include time-domain and / or frequency-domain resources.

[0167] For example, the location corresponding to the time-frequency domain resources of the CFR is the first resource block, and the location corresponding to the time-frequency domain resources of the initial DL BWP is the second resource block, wherein the second resource block covers the first resource block. Here, the second resource block may cover the first resource block in the time domain and / or frequency domain, which is not limited in this disclosure. It should be noted that if the location of the time-frequency domain resources of the CFR is within the location of the time-frequency domain resources of the initial DL BWP, the second resource block may completely cover the first resource block. Here, the first resource block may be a sub-resource block of the second resource block, wherein the second resource block may contain multiple sub-resource blocks.

[0168] In one embodiment, the sum of the bandwidth ranges of the CFR and the initial DL BWP is within the bandwidth range supported by the first type of terminal. Here, the first type of terminal may be a RedCap terminal. When the first type of terminal determines that the sum of the bandwidth ranges of the CFR and the initial DL BWP is within the bandwidth range supported by the first type of terminal, it is determined that the network device is configured such that the sum of the bandwidth ranges of the CFR and the initial DL BWP is within the bandwidth range supported by the first type of terminal.

[0169] For example, the frequency range of CFR corresponds to a first bandwidth, and the frequency range of the initial DL BWP corresponds to a second bandwidth, wherein both the first bandwidth and the second bandwidth are less than or equal to the bandwidth supported by the first type of terminal. In one embodiment, the first bandwidth may be less than the second bandwidth. Here, the first type of terminal may be a RedCap terminal; the initial DL BWP may be sent to the first type of terminal via a Master Information Block (MIB).

[0170] It should be noted that in the relevant technologies, the bandwidth corresponding to the frequency range of the initial DL BWP sent through the MIB can only be less than the bandwidth supported by the terminal. However, the bandwidth corresponding to the frequency range of the initial DL BWP sent through the System Information Block (SIB) can be greater than the bandwidth supported by the terminal, or it can be less than or equal to the bandwidth supported by the terminal.

[0171] In one embodiment, the first type of terminal can determine whether to perform monitoring processing operations for MBS based on the received CFR and initial DL BWP. That is, in response to determining the predetermined resource configuration of the network device based on the received CFR and initial DL BWP, it determines whether to receive MBS provided by the network device.

[0172] In one embodiment, in response to a first-type terminal determining that the network device configures an initial DL BWP containing a CFR and / or the sum of the bandwidth ranges of the initial DL BWP and CFR is within the bandwidth supported by the first-type terminal, the first-type terminal determines that the network device provides MBS to the first-type terminal. Alternatively, in response to a first-type terminal determining that: the network device does not provide MBS to the first-type terminal, the network device does not configure a CFR, or the initial DL BWP configured by the network device may not contain a CFR, or the sum of the bandwidth ranges of the initial DL BWP and CFR configured by the network device is not within the bandwidth supported by the first-type terminal, the first-type terminal determines that the network device does not provide MBS to the first-type terminal. Accordingly, the first-type terminal may determine not to perform monitoring processing operations for MBS; that is, the first-type terminal may determine that the network device does not provide MBS service to the first-type terminal. In one embodiment, the initial DL BWP and CFR have been configured before performing step 21, wherein the configured CFR is a CFR configured for non-RedCap terminals. In one embodiment, in response to the location of the time-frequency domain of the configured CFR not being included in the location of the time-frequency domain of the initial DLBWP, the first type of terminal will receive the CFR configured by the network device for use by the first type of terminal; or, in response to the location of the time-frequency domain of the configured CFR being included in the location of the time-frequency domain of the initial DLBWP, the first type of terminal will not receive the CFR configured by the network device for use by the first type of terminal.

[0173] For example, if the CFR already configured for a non-RedCap terminal is CORESET#0, and the initial DL BWP that has already been configured is also CORESET#0, then the position of the time-frequency domain of the configured CFR is included within the position of the time-frequency domain of the initial DL BWP. Alternatively, if the CFR already configured for a non-RedCap terminal is SIB1-configured, and the initial DL BWP that has already been configured is CORESET#0, then the position of the time-frequency domain of the configured CFR is not included within the position of the time-frequency domain of the initial DL BWP.

[0174] In this disclosure, the configuration result can be determined based on the configuration information.

[0175] In one embodiment, the network device configures predetermined resources and sends configuration information indicating the predetermined resources to a first type of terminal. Upon receiving the configuration information, the first type of terminal can perform processing operations on the MBS based on the configuration information. For example, in response to the initial DL BWP containing a CFR, the first type of terminal listens to the MBS; or, in response to the initial DL BWP not containing a CFR, the first type of terminal does not listen to the MBS; or, in response to the initial DL BWP and CFR being within the bandwidth supported by the terminal, the first type of terminal listens to the MBS; or, in response to the initial DL BWP and CFR not being within the bandwidth supported by the terminal, the first type of terminal does not listen to the MBS. Here, the first type of terminal may be a terminal in a Radio Resource Control (RRC) disconnected state.

[0176] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0177] like Figure 9 As shown in the embodiments of this disclosure, a method for monitoring MBS is provided, wherein the method is executed by a first type of terminal, and the method includes:

[0178] Step 91: In response to the initial DL BWP containing CFR, listen to MBS;

[0179] or,

[0180] In response to the initial DL BWP not containing CFR, MBS is not monitored;

[0181] or,

[0182] In response to the initial DL BWP and CFR, the MBS is monitored within the bandwidth supported by the first type of terminal;

[0183] or,

[0184] In response to the initial DL BWP and CFR not being within the bandwidth supported by the first type of terminal, MBS is not monitored.

[0185] Here, the initial DL BWP is the initial DL BWP for use by the first type of terminal.

[0186] In one embodiment, a first-type terminal receives configuration information sent by a network device, wherein the configuration information indicates a predetermined resource. The predetermined resource may include a Configuration Frame Rate (CFR), and in response to determining that a CFR is configured, the first-type terminal listens to the MBS; wherein the CFR is included within the initial DL BWP, or the CFR and the initial DL BWP are within the bandwidth supported by the terminal. Here, the CFR is a CFR configured specifically for the first-type terminal. The first-type terminal may be a RedCap terminal.

[0187] In one embodiment, a first-type terminal receives configuration information sent by a network device, wherein the configuration information indicates a predetermined resource. The predetermined resource may include a CFR and / or an initial DL BWP, and the first-type terminal compares the initial DL BWP with the CFR. In one embodiment, in response to the initial DL BWP containing the predetermined resource, the first-type terminal listens to the MBS; or, in response to the initial DL BWP not containing the predetermined resource, the first-type terminal does not listen to the MBS.

[0188] In one embodiment, a first-type terminal receives configuration information sent by a network device, wherein the configuration information indicates predetermined resources. The predetermined resources include a CFR and / or an initial DL BWP. The first-type terminal compares the bandwidth corresponding to the initial DL BWP, the bandwidth corresponding to the CFR, and the bandwidth supported by the first-type terminal. In one embodiment, in response to the bandwidth of the initial DL BWP and CFR being within the bandwidth supported by the first-type terminal, the first-type terminal listens to the MBS; or, in response to the bandwidth of the initial DL BWP and CFR not being within the bandwidth supported by the first-type terminal, the first-type terminal does not listen to the MBS.

[0189] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0190] like Figure 10 As shown in the embodiments of this disclosure, a method for monitoring MBS is provided, wherein the method is executed by a first type of terminal, and the method includes:

[0191] Step 101: In response to determining that a CFR is configured for use by the first type of terminal, monitor the MBS based on the CFR used by the first type of terminal;

[0192] The CFR for use by the first type of terminal is included in the initial DL BWP, or the CFR for use by the first type of terminal and the initial DL BWP are within the bandwidth supported by the first type of terminal.

[0193] Here, the first type of terminal is a RedCap terminal in the RRC non-connected state.

[0194] Here, the first type of terminal is determined to be configured with a CFR for use by the first type of terminal, that is, the time-frequency domain position of the CFR for use by the second type of terminal is not included in the time-frequency domain position of the initial DL BWP.

[0195] In one embodiment, the location corresponding to the time-frequency domain resources of the CFR used by the second type of terminal is the first resource block, and the location corresponding to the time-frequency domain resources of the initial DL BWP is the second resource block. If the second resource block does not cover the first resource block, then the time-frequency domain location of the CFR used by the second type of terminal is not included in the time-frequency domain location of the initial DL BWP. Here, it may be that the second resource block does not cover the first resource block in the time domain and / or frequency domain, which is not limited in this disclosure. Here, the time-frequency domain location of the CFR used by the second type of terminal not being included in the time-frequency domain location of the initial DL BWP may be that the second resource block does not completely cover the first resource block.

[0196] In one embodiment, in response to the fact that the time-frequency domain location of the CFR used by the second type of terminal is not included in the time-frequency domain location of the initial DL BWP, the network device configures the CFR used by the first type of terminal. The first type of terminal receives configuration information sent by the network device, the configuration information including the CFR used by the first type of terminal; after receiving the configuration information, the first type of terminal can perform processing operations for MBS based on the configuration information. For example, in response to the initial DL BWP containing the CFR, the first type of terminal monitors MBS; or, in response to the initial DL BWP not containing the CFR, the first type of terminal does not monitor MBS; or, in response to the initial DL BWP and CFR being within the bandwidth supported by the first type of terminal, the first type of terminal monitors MBS; or, in response to the initial DL BWP and CFR not being within the bandwidth supported by the first type of terminal, the first type of terminal does not monitor MBS.

[0197] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0198] like Figure 11 As shown in the embodiments of this disclosure, a method for monitoring MBS is provided, wherein the method is executed by a first type of terminal, and the method includes:

[0199] Step 111: In response to the first type of terminal listening to predetermined information on the initial DL BWP and reaching the timing for listening to MBS, switch to listening to MBS on CFR.

[0200] Here, the first type of terminal is a RedCap terminal in the RRC non-connected state.

[0201] In one embodiment, a first-type terminal receives configuration information sent by a network device, wherein the configuration information indicates a reserved resource. The reserved resource includes a CFR and / or an initial DL BWP, and the terminal compares the initial DL BWP with the CFR. In one embodiment, in response to the initial DL BWP not containing a CFR, the first-type terminal still listens to the MBS.

[0202] In one embodiment, in response to the first type of terminal listening for paging messages on the initial DL BWP and reaching the point where it is listening for MBS, the system switches to listening for MBS on the CFR. In response to the end of MBS listening on the CFR, the system switches back to listening for paging messages on the initial DL BWP.

[0203] In one embodiment, in response to the first type of terminal listening for random access messages on the initial DL BWP and reaching the time for listening for MBS, the system switches to listening for MBS on the CFR. In response to the end of MBS listening on the CFR, the system switches to listening for random access messages on the initial DL BWP.

[0204] Furthermore, after performing step 111, the method is as follows: Figure 12 The following are also shown:

[0205] Step 121: In response to the end of listening to the MBS on the CFR, switch to listening to the predetermined information on the initial DL BWP.

[0206] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0207] like Figure 13 As shown in the embodiments of this disclosure, a method for monitoring MBS is provided, wherein the method is executed by a first type of terminal, and the method includes:

[0208] Step 131: In response to the conflict between the timing of listening to the scheduled information and the timing of listening to the MBS, determine the listening operation based on the priority level of listening to the scheduled information and listening to the MBS.

[0209] The listening operation includes: listening to scheduled information or listening to MBS.

[0210] Here, the first type of terminal is a RedCap terminal in the RRC non-connected state.

[0211] In one embodiment, a first-type terminal receives configuration information sent by a network device, wherein the configuration information indicates a predetermined resource. The predetermined resource includes a CFR and / or an initial DL BWP, and the first-type terminal compares the initial DL BWP with the CFR. In one embodiment, in response to the initial DL BWP not containing a CFR, the first-type terminal still listens to the MBS.

[0212] In one embodiment, in response to the timing of listening to the predetermined information and listening to the MBS being the same, a listening operation is determined based on the priority level of listening to the predetermined information and listening to the MBS; wherein, the listening operation includes: listening to the predetermined information or listening to the MBS.

[0213] In one embodiment, a priority level for listening to predetermined information and a priority level for listening to MBS are preset. In another embodiment, in response to a conflict between the timing of listening to predetermined information and the timing of listening to MBS, and if the priority level of listening to predetermined information is higher than the priority level of listening to MBS, the predetermined information is listened to. It should be noted that, in this disclosure, "higher than" has the meaning of "higher than or equal to" in a specific scenario.

[0214] In one embodiment, a priority level for listening to predetermined information and a priority level for listening to MBS are preset. In another embodiment, in response to a conflict between the timing of listening to predetermined information and the timing of listening to MBS, and if the priority level of listening to predetermined information is lower than the priority level of listening to MBS, MBS is listened to. It should be noted that, in this disclosure, "lower than" has the meaning of "lower than or equal to" in a specific scenario.

[0215] Here, the reservation information can be information carried by paging messages or random access messages.

[0216] Furthermore, after completing step 131, the method is as follows: Figure 14 The following are also shown:

[0217] Step 141: Determine the priority level of the MBS to be monitored based on its type.

[0218] That is, the priority level in step 131 can be determined, for example, by step 141.

[0219] In one embodiment, in response to the importance parameter of MBS being greater than a parameter threshold, the priority level of the monitored MBS is determined to be greater than a level threshold; or, in response to the importance parameter of MBS being less than a parameter threshold, the priority level of the monitored MBS is determined to be less than a level threshold.

[0220] For example, if the MBS is an alert message MBS and its importance parameter is greater than a threshold, then the priority level of the monitored MBS is greater than the threshold. Here, the priority level of the monitored MBS can be higher than the priority of the pre-defined information. The pre-defined information can be information carried by a paging message or a random access message.

[0221] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0222] like Figure 15 As shown in the embodiments of this disclosure, a resource determination apparatus is provided, wherein the apparatus includes:

[0223] The determination module 151 is used to: determine the reserved resources based on the reserved information;

[0224] The predetermined information indicates that the first type of terminal will be provided with multicast and broadcast services (MBS) or not provided with MBS services; the predetermined resources include at least one of the following: common frequency resources (CFR) and the initial downlink bandwidth portion (DL BWP) for use by the first type of terminal.

[0225] It should be noted that those skilled in the art will understand that the execution module 151 described above can be configured to perform any one of the aforementioned steps 21 to 71, which will not be elaborated further here.

[0253] Other embodiments of the invention will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This disclosure is intended to cover any variations, uses, or adaptations of the invention that follow the general principles of the invention and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of the invention are indicated by the following claims.

[0254] The method of this disclosure embodiment may include at least one of the following:

[0255] Method 1:

[0256] In one embodiment, on the network side, the network determines the configuration of CFR and / or RedCap initial DL BWP based on whether MBS services are provided to RedCap terminals. If the network determines that related MBS services are provided to RedCap, it needs to support the RedCap Initial DL BWP to include CFR or the terminal's UE bandwidth to simultaneously monitor Initial DL BWP or CFR. Otherwise, the network does not consider the aforementioned limitations during configuration.

[0257] In one embodiment, the terminal determines whether it needs to monitor MBS services by comparing the configuration of CFR with the configuration of initial DL BWP. If the monitored initial DL BWP cannot cover CFR or the terminal's UE bandwidth cannot monitor either initial DL BWP or CFR at the same time, then the terminal will not monitor MBS.

[0258] Method 2:

[0259] In one embodiment, the network side determines whether the initial DL BWP includes the first CFR or whether the UE bandwidth at the network end can simultaneously monitor the initial DL BWP or CFR by comparing the positions of the RedCap initial DL BWP and the first CFR. If the conditions are not met, the network can configure a second CRF for RedCap. The second CFR needs to be included within the RedCap initial DL BWP or ensure that the second CRF and the RedCap initial DL BWP are within the UE bandwidth of RedCap.

[0260] In one embodiment, on the terminal side, it is determined whether there is a second CFR for RedCap. MBS services are received on the second CFR.

[0261] Method 3:

[0262] In one embodiment, the RedCap terminal receives MBS and monitors idle / inactive messages (e.g., paging, RACH) via BWP switching. Specifically, the terminal switches to CFR resources when it needs to receive MBS. After receiving the MBS, the terminal switches back to the initial DL BWP to receive information.

[0263] In one embodiment, when the terminal receives MBS and receives information in the idle / inactive state, such as paging, RACH, etc., there is a conflict:

[0264] In one embodiment, a receiving priority is defined; for example, MBS reception is always a low priority.

[0265] In one embodiment, the terminal determines the priority based on the type of MBS service. For example, if the MBS service subscribed to is for alert information, then the MBS service takes priority.

[0266] It should be understood that the present invention is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of the invention is limited only by the appended claims.
