Description

Technical Field

[0002] Currently, the 3rd Generation Partnership Project (3GPP) has carried out research on the Reduced Capability NR Devices (REDCAP) project. The goal is to reduce the complexity of User Equipment (UE) and save costs on the premise of coexisting with R15 (3GPP Release 15) or R16 (3GPP Release 16) User Equipment (UE).

[0095] Please refer to Figure 1, which shows a schematic structural diagram of a wireless communication system provided by an embodiment of the present disclosure. As Figure 1 shown, the wireless communication system is a communication system based on cellular mobile communication technology. The wireless communication system may include: a plurality of user equipments 110 and a plurality of base stations 120.

[0096] Among them, the user equipment 110 may be a device that provides voice and / or data connectivity to users. The user equipment 110 may communicate with one or more core networks via a Radio Access Network (RAN). The user equipment 110 may be an Internet of Things (IoT) user equipment, such as a sensor device, a mobile phone (or referred to as a "cellular" phone), and a computer with an IoT user equipment. For example, it may be a fixed, portable, pocket-sized, handheld, computer-integrated, or vehicle-mounted device. For example, a Station (STA), a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, a user device, or a user equipment. Or, the user equipment 110 may also be a device of an unmanned aerial vehicle. Or, the user equipment 110 may also be a vehicle-mounted device, such as a vehicle-mounted computer with wireless communication function, or a wireless user equipment external to the vehicle-mounted computer. Or, the user equipment 110 may also be a roadside device, such as a street lamp, a signal lamp, or other roadside devices with wireless communication function.

[0097] The base station 120 may be a network-side device in the wireless communication system. Among them, the wireless communication system may be a fourth-generation mobile communication technology (4G) system, also known as the Long Term Evolution (LTE) system; or, the wireless communication system may also be a 5G system, also known as the New Radio system or 5G NR system. Or, the wireless communication system may also be the next-generation system of the 5G system. Among them, the access network in the 5G system may be referred to as the New Generation-Radio Access Network (NG-RAN).

[0098] Among them, the base station 120 may be an evolved Node B (eNB) adopted in a 4G system. Alternatively, the base station 120 may also be a gNode B (gNB) with a centralized distributed architecture adopted in a 5G system. When the base station 120 adopts a centralized distributed architecture, it generally includes a central unit (CU) and at least two distributed units (DUs). A protocol stack of the Packet Data Convergence Protocol (PDCP) layer, the Radio Link Control (RLC) layer, and the Medium Access Control (MAC) layer is provided in the central unit; a Physical (PHY) layer protocol stack is provided in the distributed unit. The specific implementation manner of the base station 120 is not limited in the embodiments of the present disclosure.

[0099] A wireless connection can be established between the base station 120 and the user equipment 110 through a wireless air interface. In different embodiments, the wireless air interface is a wireless air interface based on the fourth-generation mobile communication network technology (4G) standard; alternatively, the wireless air interface is a wireless air interface based on the fifth-generation mobile communication network technology (5G) standard, such as the new air interface; or the wireless air interface may also be a wireless air interface based on the next-generation mobile communication network technology standard of 5G.

[0100] In some embodiments, an E2E (End to End) connection can also be established between user equipments 110. For example, in vehicle-to-everything (V2X) communication scenarios such as vehicle-to-vehicle (V2V) communication, vehicle-to-infrastructure (V2I) communication, and vehicle-to-pedestrian (V2P) communication.

[0101] Here, the above user equipment can be regarded as the terminal equipment in the following embodiments.

[0102] In some embodiments, the above wireless communication system may further include a network management device 130.

[0103] A plurality of base stations 120 are respectively connected to a network management device 130. Among them, the network management device 130 may be a core network device in a wireless communication system. For example, the network management device 130 may be a Mobility Management Entity (MME) in an Evolved Packet Core (EPC). Alternatively, the network management device may also 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), etc. The embodiments of the present disclosure do not limit the implementation form of the network management device 130.

[0104] For the convenience of those skilled in the art to understand, the embodiments of the present disclosure list multiple implementation manners to clearly illustrate the technical solutions of the embodiments of the present disclosure. Of course, those skilled in the art can understand that the multiple embodiments provided by the embodiments of the present disclosure can be executed alone, or can be executed together after being combined with the methods of other embodiments in the embodiments of the present disclosure, or can be executed alone or in combination with some methods in other related technologies; the embodiments of the present disclosure do not make any limitations in this regard.

[0105] After the introduction of the Redcap UE, an uplink initial BWP or a downlink initial BWP can be separately configured for the Redcap UE in SIB1. Usually, the Redcap UE will preferentially use the uplink initial BWP / downlink initial BWP separately configured for the Redcap UE. Only in the scenario where the network does not have an uplink initial BWP / downlink initial BWP separately configured for the Redcap UE, the Redcap UE can use the uplink initial BWP / downlink initial BWP of a traditional (legacy) UE.

[0106] The downlink initial BWP separately configured for the Redcap UE can be: initialDownlinkBWP-RedCap, and the downlink initial BWP configured for a traditional (legacy) UE (all types of UEs) can be: initialDownlinkBWP.

[0107] If initialDownlinkBWP-RedCap exists, the RedCap UE uses initialDownlinkBWP-RedCap instead of initialDownlink BWP. If the locationAndBandwidth of this initialDownlinkBWP-RedCap contains the entire CORESET#0, the RedCap UE applies the locationAndBandwidth when receiving this field (e.g., determines the frequency location of the signal related to this locationAndBandwidth), but the RedCap UE uses CORESET#0 until it receives RRCSetup / RRCResume / RRC re-establishment. Otherwise, i.e., if the locationAndBandwidth of this BWP does not contain the entire CORESET#0, the UE uses this BWP to receive downlink messages during initial access (Msg2, MsgB, Msg4) and after initial access.

[0108] If initialDownlinkBWP-RedCap does not exist, the RedCap UE uses initialDownlinkBWP, provided that the initialDownlinkBWP does not exceed the maximum bandwidth of the RedCap UE.

[0109] It can be seen that: when the bandwidth of initialDownlinkBWP-RedCap includes the entire CORESET#0, the terminal will use this initial BWP after receiving the RRC message, and will use CORESET#0 before receiving the RRC message. If the bandwidth of this initial BWP does not include the entire CORESET#0, the terminal uses this initial BWP for receiving messages during the random access procedure (Msg2, MsgB, Msg4).

[0110] The control channel configuration on the initial BWP is specified as follows:

[0111] That is, for the downlink initial BWP that does not include CORESET#0 and CD-SSB, the search space for paging messages and the search space for system messages (including SIB1 and other SIB messages) are not allowed.

[0112] Paging for users introduces Paging Earlier Indication (PEI), which is used to indicate whether the UE needs to monitor subsequent Paging Occasions (POs). Paging packet information can be carried in the PEI. The set of PEI parameters can be broadcast in the system message, that is, the PEI for multiple downlink initial BWPs is shared;

[0113] However, not all downlink initial BWPs have CD-SSBs, etc., that is, not all downlink initial BWPs can be configured with paging messages. And in the Release 18 standard, that is, in the enhanced-capability reduced UE (e-Redcap) in the R18 standard, not all initial BWPs have CD-SSBs.

[0114] Therefore, under different downlink initial BWP configurations, how to configure the set of PEI parameters and implement the corresponding PEI configuration for different configured downlink initial BWPs is an urgent problem to be solved.

[0115] As Figure 2 shown, an information transmission method provided by an embodiment of the present disclosure is executed by a base station and includes:

[0116] Step 201: Determine a set of paging earlier indication (PEI) parameters associated with a specific downlink initial BWP, where the set of PEI parameters is at least used for the UE to determine the monitoring resources of the PEI associated with the specific downlink initial BWP.

[0117] Here, the monitoring resources indicated by the set of PEI parameters include, but are not limited to, at least one of the following: the search space for PEI monitoring; the first monitoring moment of the PEI.

[0118] In a possible implementation, the specific downlink initial BWP may include at least one of the following:

[0119] A specific downlink initial BWP;

[0120] The downlink initial BWP of a specific type of UE;

[0121] The downlink initial BWP that meets a predetermined condition.

[0122] In a possible implementation, the downlink initial BWP that meets a predetermined condition may include: the downlink initial BWP that can be configured with a paging message.

[0123] In a possible implementation, the sets of PEI parameters associated with different specific downlink initial BWPs are different.

[0124] The set of paging early indication (PEI) parameters determined for a specific downlink initial BWP may include: determining a corresponding set of PEI parameters for each downlink initial BWP. That is, one set of PEI parameters corresponds to one downlink initial BWP.

[0125] In a possible implementation, the base station may also configure a common set of PEI parameters for multiple downlink initial BWPs. That is, the listening resources of the PEI in one downlink initial BWP include: a part of the listening resources indicated by the common set of PEI parameters, and another part of the listening resources indicated by the set of PEI parameters configured separately for the PEI of the downlink initial BWP.

[0126] In a possible implementation, the set of PEI parameters used by the base station and the terminal may be divided into two parts. That is, parameter set 1 is configured commonly for multiple downlink initial BWPs, and parameter set 2 is configured separately for the PEI of a certain downlink initial BWP.

[0127] In a possible implementation, PEI parameter set 1 (pei-Config) is carried by DownlinkConfigCommonSIB;

[0128] In a possible implementation, PEI parameter set 2 may be carried by PDCCH-ConfigCommon. Here, PDCCH-ConfigCommon may be carried in the system message. For example, PDCCH-ConfigCommon may be carried in system information block 1 (SIB1).

[0129] In a possible implementation, PEI parameter set 2 may be carried by pei-ConfigBWP in PDCCH-ConfigCommon.

[0130] In this way, by determining the set of PEI parameters associated with a specific downlink initial BWP, a set of PEI parameters can be configured separately for a specific downlink initial BWP, instead of multiple downlink initial BWPs sharing the same set of PEI parameters, which improves the flexibility of the configuration of the set of PEI parameters and meets the requirements of different downlink initial BWPs for the set of PEI parameters.

[0131] In an embodiment, the specific downlink initial BWP includes at least one of the following items:

[0132] The downlink initial BWP configured with a paging search space;

[0133] The downlink initial BWP including the transmission resources of the first type of control resource set #0 (CORESET #0), where the first type of CORESET #0 is at least associated with the first type of UE;

[0134] The downlink initial BWP including the transmission resources of the second type of CORESET #0, where the second type of CORESET #0 is associated with a second type of UE, and a first type of UE is different from the second type of UE;

[0135] The downlink initial BWP configured with the cell-defined synchronization signal CD-SSB;

[0136] The downlink initial BWP configured with the non-cell-defined synchronization signal NCD-SSB;

[0137] The downlink initial BWP including the transmission resources of the first type of CORESET #0 and configured with the CD-SSB;

[0138] The downlink initial BWP including the transmission resources of the second type of CORESET #0 and configured with the CD-SSB.

[0139] Here, the set of PEI parameters can be conditionally configured, that is, the set of PEI parameters is configured for the downlink initial BWP only when the downlink initial BWP meets the above conditions.

[0140] The set of PEI parameters is used to indicate the monitoring resources of the PEI, and the PEI is used to indicate to the UE whether it is necessary to monitor a predetermined PO. Here, the predetermined PO can include one or more POs after the PEI.

[0141] Therefore, for the downlink initial BWP, if it is necessary for the UE to monitor the PEI, configure the set of PEI parameters. For example, if there is no paging message in the downlink initial BWP, then the UE does not need to monitor the paging message, let alone the PEI. Therefore, the set of PEI parameters can be not configured.

[0142] Here, the first type of CORESET #0 can be the CORESET #0 for the first type of UE and the second type of UE.

[0143] The first type of UE can be a non-capability-reduced UE, such as an eMMB UE, etc.

[0144] The second type of CORESET #0 can be the CORESET #0 for the second type of UE. For example, the second type of CORESET #0 can be the CORESET #0 for the capability-reduced UE in the 3GPP Release 18 (R18) standard.

[0145] In a possible implementation, the downlink initial BWP supported by the first type of UE is greater than or equal to that of the second type of UE.

[0146] For example, the downlink initial BWP supported by the first type of UE is greater than or equal to 20Mhz. The downlink initial BWP supported by the second type of UE is less than or equal to 20Mhz.

[0147] In a possible implementation, the bandwidth of the first type of CORESET#0 is greater than the bandwidth of the second type of CORESET#0.

[0148] In one embodiment, the second type of UE includes at least one of the following:

[0149] UE with reduced capabilities;

[0150] UE with enhanced reduced capabilities (eRedCap).

[0151] For example, when the PDCCH-ConfigCommon associated with the downlink initial BWP configures the paging early indication (PEI) parameter set associated with a specific downlink initial bandwidth part BWP, it needs to meet the conditions indicated by the InitialBWP-Paging field, for configuring the paging early indication (PEI) parameter set associated with a specific downlink initial bandwidth part BWP. That is, when the downlink initial BWP meets one of the following conditions, the downlink can optionally configure the paging early indication (PEI) parameter set associated with a specific downlink initial bandwidth part BWP on the downlink initial BWP. That is, the downlink initial BWP needs to meet at least one of the following conditions (i.e., the configuration prerequisite conditions) to optionally configure the PEI parameter set on this downlink initial BWP:

[0152] Configured with a paging search space (paging-SearchSpace);

[0153] The location and bandwidth (LocationAndBandwith) of the downlink initial BWP includes CORESET#0;

[0154] The location and bandwidth (LocationAndBandwith) of the downlink initial BWP includes CORESET#0, and the downlink initial BWP includes a CD-SSB;

[0155] The location and bandwidth (LocationAndBandwith) of the downlink initial BWP includes CORESET#0, and the downlink initial BWP includes an SSB (including a CD-SSB and an NCD-SSB).

[0156] In this way, by determining the PEI parameter set associated with a specific downlink initial BWP, the listening resources of the PEI can be indicated to the UE. Furthermore, the UE can listen to the PEI, and then listen to the PO when needed, saving the UE's power. On the other hand, not configuring the PEI parameter set on the downlink initial BWP that cannot transmit paging messages reduces useless configurations and saves resources.

[0157] Such as Figure 3As shown in the figure, an embodiment of the present disclosure provides an information transmission method, which is executed by a base station and includes:

[0158] Step 301: Send the PEI listening indication information indicating the set of PEI parameters to the UE.

[0159] Step 301 can be implemented independently or in combination with Step 201.

[0160] The base station can send the PEI listening indication information to the UE. After receiving the PEI listening indication information, the UE can determine the set of paging early indication (PEI) parameters associated with a specific downlink initial BWP.

[0161] In one embodiment, the specific downlink initial BWP includes a downlink initial BWP for a second type of UE, where the downlink initial BWP for the second type of UE is different from the downlink initial BWP used by a first type of UE.

[0162] In a possible implementation, the bandwidth of the downlink initial BWP for the second type of UE is less than or equal to the bandwidth of the downlink initial BWP used by the first type of UE.

[0163] Here, it is possible to determine only the configuration conditions for the set of PEI parameters of the downlink initial BWP (initialDownlinkBWP-RedCap) of the second type of UE. The second type of UE may include eRedCap UE in the 3GPP Release 17 (R17) standard and eRedCap UE in the 3GPP Release 18 (R18) standard.

[0164] In a possible implementation, the downlink initial BWP used by the first type of user already defaults to meeting the above preconditions for the PEI configuration parameters.

[0165] Due to the diversity of the downlink initial BWP for the second type of UE, for example, not all downlink initial BWPs for the second type of UE have CD-SSB. Therefore, it is possible to determine the set of PEI parameters for the downlink initial BWP of the second type of UE that meets the conditions.

[0166] The downlink initial BWP of the second type of UE that meets the conditions is the above-mentioned specific downlink initial BWP.

[0167] In a possible implementation, the UE listens for the PEI on the specific downlink initial BWP having the set of PEI parameters.

[0168] The base station can send the PEI listening indication information to the UE. In this way, the UE can determine whether the downlink initial BWP has a set of PEI parameters.

[0169] If the downlink initial BWP has a set of PEI parameters, the UE can monitor the PEI based on the set of PEI parameters.

[0170] If the downlink initial BWP does not have a set of PEI parameters, the UE may not monitor the PEI. For example, the UE can monitor all POs.

[0171] In a possible implementation, the UE selects the specific downlink initial BWP corresponding to the type of the UE according to the type of the UE, and monitors the PEI.

[0172] The UE can monitor the specific downlink initial BWP corresponding to its own type based on its own type.

[0173] In a possible implementation, the UE monitors the downlink initial BWP based on a predetermined rule.

[0174] The predetermined rule may include: the UE monitors the specific downlink initial BWP corresponding to its own type.

[0175] For example, since the RedCap UE supports a smaller bandwidth of the downlink initial BWP (e.g., less than 20 MHz), the base station may be configured with a downlink initial BW for the RedCap UE (e.g., a bandwidth of 5M). The RedCap UE can select the specific downlink initial BWP for the RedCap UE to monitor the PEI.

[0176] In a possible implementation, the UE uses the following expression (1)) to determine the specific downlink initial BWP for monitoring the PEI:

[0177] Index = UE-ID mod N (1)

[0178] Wherein, the Index represents the index of the downlink initial BWP corresponding to the PEI monitored by the UE, the UE-ID represents the identifier of the UE, and N represents the total number of the specific downlink initial BWPs having the set of PEI parameters.

[0179] There may be multiple specific downlink initial BWPs having a set of PEI parameters. The base station can set the paging message of the UE in one of the specific downlink initial BWPs. The base station can determine the specific downlink initial BWP for sending the paging message based on expression (1). The UE determines the specific downlink initial BWP based on the same rule and monitors the PEI in the specific downlink initial BWP.

[0180] As Figure 4 shown, an information transmission method provided by an embodiment of the present disclosure is executed by a user equipment UE, including:

[0181] Step 401: Receive the PEI listening indication information sent by the base station to indicate the set of PEI parameters, where the set of PEI parameters is associated with a specific downlink initial BWP, and the set of PEI parameters is at least used for the UE to determine the listening resources of the PEI associated with the specific downlink initial BWP.

[0182] Here, the listening resources indicated by the set of PEI parameters include, but are not limited to, at least one of the following: the search space for PEI listening; the first listening moment of the PEI.

[0183] In a possible implementation, the specific downlink initial BWP may include at least one of the following items:

[0184] A specific downlink initial BWP;

[0185] The downlink initial BWP of a specific type of UE;

[0186] The downlink initial BWP that meets a predetermined condition.

[0187] In a possible implementation, the downlink initial BWP that meets a predetermined condition may include: the downlink initial BWP capable of configuring a paging message.

[0188] In a possible implementation, the sets of PEI parameters associated with different specific downlink initial BWPs are different.

[0189] Determining the set of paging early indication (PEI) parameters associated with a specific downlink initial BWP may include: determining the corresponding set of PEI parameters for each downlink initial BWP. That is, one set of PEI parameters corresponds to one downlink initial BWP.

[0190] In a possible implementation, the base station may also configure a shared set of PEI parameters for multiple downlink initial BWPs. That is, the listening resources of the PEI in one downlink initial BWP include: a part of the listening resources indicated by the shared set of PEI parameters, and another part of the listening resources indicated by the set of PEI parameters configured separately for the PEI of the downlink initial BWP.

[0191] In a possible implementation, the sets of PEI parameters used by the base station and the terminal can be divided into two parts. That is, parameter set 1 is configured shared for multiple downlink initial BWPs, and parameter set 2 is configured separately for the PEI of a certain downlink initial BWP.

[0192] In a possible implementation, the PEI parameter set 1 (pei-Config) is carried by DownlinkConfigCommonSIB;

[0193] In a possible implementation, the PEI parameter set 2 may be carried by PDCCH-ConfigCommon. Here, PDCCH-ConfigCommon may be carried in the system message. For example, PDCCH-ConfigCommon may be carried in System Information Block 1 (SIB1).

[0194] In a possible implementation, the PEI parameter set 2 may be carried by pei-ConfigBWP in PDCCH-ConfigCommon.

[0195] The base station may send PEI listening indication information to the UE. After receiving the PEI listening indication information, the UE may determine the paging early indication PEI parameter set associated with a specific downlink initial BWP.

[0196] In this way, by determining the PEI parameter set associated with a specific downlink initial BWP, the PEI parameter set can be configured separately for the specific downlink initial BWP, instead of multiple downlink initial BWPs sharing the same PEI parameter set, which improves the flexibility of the PEI parameter set configuration and meets the requirements of different downlink initial BWPs for the PEI parameter set.

[0197] In one embodiment, the specific downlink initial BWP includes at least one of the following items:

[0198] The downlink initial BWP configured with a paging search space;

[0199] The downlink initial BWP including the transmission resources of the first type of control resource set #0 CORESET #0, where the first type of CORESET #0 is at least associated with the first type of UE;

[0200] The downlink initial BWP including the transmission resources of the second type of CORESET #0, where the second type of CORESET #0 is associated with the second type of UE, and the first type of UE is different from the second type of UE;

[0201] The downlink initial BWP configured with the cell-defined synchronization signal CD-SSB;

[0202] The downlink initial BWP configured with the non-cell-defined synchronization signal NCD-SSB;

[0203] The downlink initial BWP including the transmission resources of the first type of CORESET #0 and configured with the CD-SSB;

[0204] The downlink initial BWP including the transmission resources of the second type of CORESET #0 and configured with the CD-SSB.

[0205] Here, the PEI parameter set can be a conditional configuration, that is, the PEI parameter set is configured for the downlink initial BWP only when the downlink initial BWP meets the above conditions.

[0206] Here, the PEI parameter set can be an optional configuration, that is, the PEI parameter set is optionally configured for the downlink initial BWP only when the downlink initial BWP meets the above conditions. If the above conditions are not met, it is necessarily not allowed to configure the PEI parameter set for the downlink initial BWP.

[0207] The PEI parameter set is used to indicate the listening resources of the PEI, and the PEI is used to indicate to the UE whether it is necessary to listen to a predetermined PO. Here, the predetermined PO can include one or more POs after the PEI.

[0208] Therefore, for the downlink initial BWP, if it is necessary for the UE to listen to the PEI, configure the PEI parameter set. For example, if there is no paging message in the downlink initial BWP, then the UE does not need to listen to the paging message, let alone listen to the PEI. Therefore, the PEI parameter set can be not configured.

[0209] Here, the first type of CORESET#0 can be the CORESET#0 for the first type of UE and the second type of UE.

[0210] The first type of UE can be a non-capability-reduced UE, such as an eMMB UE, etc.

[0211] The second type of CORESET#0 can be the CORESET#0 for the second type of UE. For example, the second type of CORESET#0 can be the CORESET#0 for the capability-reduced UE in the 3GPP Release18 (R18) standard.

[0212] In a possible implementation, the downlink initial BWP supported by the first type of UE is greater than or equal to that of the second type of UE.

[0213] For example, the downlink initial BWP supported by the first type of UE is greater than or equal to 20Mhz. The downlink initial BWP supported by the second type of UE is less than or equal to 20Mhz.

[0214] In a possible implementation, the bandwidth of the first type of CORESET#0 is greater than the bandwidth of the second type of CORESET#0.

[0215] In an embodiment, the second type of UE includes at least one of the following:

[0216] Capability-reduced UE;

[0217] Enhanced capability-reduced UE (eRedCap).

[0218] For example, the PDCCH-ConfigCommon associated with the downlink initial BWP needs to meet the conditions indicated by InitialBWP-Paging when configuring the set of paging early indication (PEI) parameters associated with a specific downlink initial bandwidth part BWP, for configuring the set of paging early indication (PEI) parameters associated with a specific downlink initial bandwidth part BWP. That is, when the downlink initial BWP meets one of the following conditions, the downlink initial BWP can optionally configure the set of paging early indication (PEI) parameters associated with a specific downlink initial bandwidth part BWP, that is, it needs to meet one of the following conditions (i.e., the configuration prerequisite condition) to optionally configure the set of PEI parameters on this downlink initial BWP:

[0219] Configured with a paging search space (paging-SearchSpace);

[0220] The location and bandwidth (LocationAndBandwith) of the downlink initial BWP contains CORESET #0;

[0221] The location and bandwidth (LocationAndBandwith) of the downlink initial BWP contains CORESET #0, and the downlink initial BWP contains a CD-SSB;

[0222] The location and bandwidth (LocationAndBandwith) of the downlink initial BWP contains CORESET #0, and the downlink initial BWP contains an SSB (including CD-SSB and NCD-SSB).

[0223] In this way, by determining the set of PEI parameters associated with a specific downlink initial BWP, the listening resources of the PEI can be indicated to the UE. Furthermore, the UE can listen to the PEI, and then listen to the PO when needed, saving the UE's power. On the other hand, the set of PEI parameters is not configured on the downlink initial BWP that cannot transmit paging messages, reducing useless configurations and saving resources.

[0224] In one embodiment, the specific downlink initial BWP includes: the downlink initial BWP for the second type of UE, where the downlink initial BWP for the second type of UE is different from the downlink initial BWP used by the first type of UE.

[0225] In a possible implementation, the bandwidth of the downlink initial BWP for the second type of UE is less than or equal to the bandwidth of the downlink initial BWP used by the first type of UE.

[0226] Here, it is possible to determine only the configuration conditions for the set of PEI parameters of the initial downlink BWP (initialDownlinkBWP-RedCap) of the second type of UE. The second type of UE may include eRedCap UE in the 3GPP Release 17 (R17) standard and eRedCap UE in the 3GPP Release 18 (R18) standard.

[0227] In a possible implementation, the initial downlink BWP used by the first type of user already defaultly satisfies the above preconditions for the PEI configuration parameters.

[0228] Due to the diversity of the initial downlink BWP for the second type of UE, for example, not all initial downlink BWPs for the second type of UE have CD-SSB. Therefore, it is possible to determine the set of PEI parameters for the initial downlink BWP of the second type of UE that meets the conditions.

[0229] The initial downlink BWP of the second type of UE that meets the conditions is the above-mentioned specific initial downlink BWP.

[0230] As Figure 5 shown, an embodiment of the present disclosure provides an information transmission method, which is executed by a user equipment UE and includes:

[0231] Step 501: Listen for the PEI on the specific initial downlink BWP having the set of PEI parameters.

[0232] Step 501 can be implemented independently or in combination with step 401.

[0233] The base station may send PEI listening indication information to the UE. In this way, the UE can determine whether the initial downlink BWP has a set of PEI parameters.

[0234] If the initial downlink BWP has a set of PEI parameters, then the UE can listen for the PEI based on the set of PEI parameters.

[0235] If the initial downlink BWP does not have a set of PEI parameters, then the UE may not listen for the PEI. For example, the UE may listen for all POs.

[0236] As Figure 6 shown, an embodiment of the present disclosure provides an information transmission method, which is executed by a user equipment UE and includes:

[0237] Step 601: Determine the specific initial downlink BWP for listening for the PEI using expression (1):

[0238] Wherein, the Index represents the index of the downlink initial BWP corresponding to the PEI listened by the UE, the UE-ID represents the identifier of the UE, and N represents the total number of the specific downlink initial BWPs with the PEI parameter set.

[0239] Step 601 can be implemented independently or in combination with Step 401 and / or Step 501.

[0240] There can be multiple specific downlink initial BWPs with the PEI parameter set. The base station can set the paging message of the UE in one of the specific downlink initial BWPs. The base station can determine the specific downlink initial BWP for sending the paging message based on Expression (1), and the UE determines the specific downlink initial BWP based on the same rule and listens for the PEI in the specific downlink initial BWP.

[0241] In one embodiment, the listening for the PEI on the specific downlink initial BWP with the PEI parameter set includes:

[0242] Select the specific downlink initial BWP corresponding to the type of the UE according to the type of the UE, and listen for the PEI.

[0243] The UE can listen for the specific downlink initial BWP corresponding to its own type based on its own type.

[0244] In a possible implementation, the UE listens for the downlink initial BWP based on a predetermined rule.

[0245] The predetermined rule can include: the UE listens for the specific downlink initial BWP corresponding to its own type.

[0246] For example, since the RedCap UE supports a smaller bandwidth of the downlink initial BWP (e.g., less than 20 MHz), the base station can be configured with a downlink initial BW for the RedCap UE (e.g., with a bandwidth of 5M). The RedCap UE can select the specific downlink initial BWP for the RedCap UE to listen for the PEI.

[0247] To further explain any embodiment of the present disclosure, a specific embodiment is provided below.

[0248] 1. Protect a method for configuring a PEI parameter set in a network;

[0249] a) The specific PEI parameter set is associated with the downlink initial BWP configuration;

[0250] b) As an embodiment, the PEI parameter set is: pei-ConfigBWP

[0251] c) As an embodiment, the PEI parameter set carries the search space for PEI monitoring and the first monitoring time of the PEI.

[0252] 2. The protocol may specify that a specific PEI parameter set can only be configured in the following initial BWP (the EI parameter set can be configured in the downlink initial BWP that meets one of the following conditions):

[0253] a) There is a paging search space (paging-SearchSpace) configured on the downlink initial BWP;

[0254] b) The downlink initial BWP must include the entire CORESET#0 (the first type of CORESET#0) / CORESET#0-bis (the second type of CORESET#0); (where CORESET#0-bis is the second type of CORESET#0, that is, the 0th control resource set introduced for subsequent R18 Redcap UEs)

[0255] c) The downlink initial BWP must include the entire CORESET#0 / CORESET#0-bis and CD-SSB;

[0256] d) The downlink initial BWP must be configured with CD-SSB;

[0257] e) The downlink initial BWP must be configured with CD-SSB or NCD-SSB.

[0258] 3. The condition that the protocol specifies a specific PEI parameter set can only be met in the following initial BWP can be for a downlink initial BWP configured for a specific type (such as initialDownlinkBWP-RedCap):

[0259] a) As an embodiment, the specific type of terminal is a Redcap type terminal of R17; or an eRedcap type terminal of R18.

[0260] 4. The terminal monitors the paging message on the selected downlink initial BWP. If there is no specific PEI parameter set configured on it, there is no need to monitor the PEI (that is, directly monitor the PO);

[0261] a) The terminal selects the downlink initial BWP to monitor the paging message based on a predetermined rule.

[0262] b) As an embodiment, the predetermined rule can take the modulo of the total number of N downlink initial BWPs according to the UE-ID (on which the paging search space is configured); monitor on the corresponding downlink initial BWP according to the modulo index;

[0263] As an example: The predefined rules can be differentiated according to user types. For example, a Redcap UE listens for paging messages on the initialDownlinkBWP-RedCap.

[0264] Therefore, in the PDCCH-ConfigCommon, in the precondition description for the configuration of the paging early indication PEI parameter set pei-ConfigBWP-r17 associated with a specific downlink initial BWP, namely Cond InitialBWP-Paging, it is necessary to explain that the paging early indication PEI parameter set pei-ConfigBWP-r17 associated with the downlink initial BWP can be optionally configured only on the downlink initial BWP that meets specific preconditions. The following are some examples of the explanation of the preconditions for InitialBWP-Paging:
