[0087] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0088] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0089] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto.

For example, if the network device is about to enter or has already entered Network Energy Saving (NES) mode to save energy, the first information may be adjusted to on-demand mode. When the first information is in on-demand mode, the network device stops sending the first information according to the configuration information of the first information and then sends the first information again after receiving the request information sent by the terminal, for example, sending the first information according to the configuration information of the first information. Therefore, it is necessary to consider how to ensure that the terminal can smoothly send the request information to the network device.

[0095] FIG2 is an interactive schematic diagram showing a method for sending information according to an embodiment of the present disclosure.

[0096] As shown in FIG2 , the information sending method may include the following steps:

[0097] In step S201, the first network device sends downlink information to the terminal.

[0098] In some embodiments, the terminal receives downlink information sent by the first network device.

[0099] In some embodiments, the downlink information is used by the terminal to determine the first configuration information.

[0100] In step S202, the terminal determines first configuration information according to the downlink information.

[0101] In some embodiments, the first configuration information is used by the terminal to send request information.

[0102] In some embodiments, the request information is used to request the first network device or other network devices to send the first information.

[0103] For example, if the first configuration information corresponds to the first cell, the first configuration information can be used by the terminal to send request information to the network device in the first cell, that is, the terminal can send request information to the network device in the first cell according to the first configuration information.

[0104] For example, if the first configuration information has no corresponding relationship with a cell, the first configuration information can be used by the terminal to send request information to the network device in any cell, that is, the terminal can send request information to the network device in any cell according to the first configuration information.

[0105] In some embodiments, the request information may correspond to a cell, or may have no correspondence with a cell.

[0106] For example, there is a corresponding relationship between the request information and the first cell, and the request information can be used to request the network device to send the first information in the first cell.

[0107] For example, if the request information has no corresponding relationship with the cell, then the request information can be used to request the network device to send the first information in any cell.

[0108] In some embodiments, the first information includes at least one of the following: SIB1; SSB, CSI-RS, TRS, PDCCH, PDSCH, other newly defined signals, such as a signal consisting of a primary synchronization signal and a secondary synchronization signal, DRS, etc.

[0109] In some embodiments, the terminal may send first request information to the first network device, requesting the first network device to send the first information in the first cell.

[0110] Among them, if the first cell is the cell of the first network device, then the first network device can send the first information in the first cell according to the request information; if the first cell is the cell of the second network device (different from the first network device), the first network device can send a request to the second network device according to the request information to request the second network device to send the first information in the first cell. In this case, the request information can be used to request other network devices (such as the second network device) to send the first information.

[0111] According to an embodiment of the present disclosure, when the terminal attempts to receive the first information but is unable to receive the first information, the terminal can determine the first configuration information based on the first indication information sent by the network device. Accordingly, it can be ensured that the terminal can successfully obtain the first configuration information, and send a request information to the network device based on the first configuration information to request the network device to send the first information, thereby enabling the terminal to receive the first information from the network device when it needs to receive the first information, so that the terminal can smoothly perform subsequent communications based on the first information.

[0112] In some embodiments, the request information may also be referred to as a wake-up signal (WUS), and the wake-up signal may request the network device to send the first information.

[0113] For example, if the network device is in the NES state, causing the first information to be in the on-demand state, the network device will stop sending the first information according to the configuration information of the first information. The wake-up signal can be used to wake up the network device, for example, to request the network device to send the first information. The network device can adjust the state of the first information to the non-on-demand state, for example, to continue sending the first information according to the configuration information of the first information. Accordingly, the first configuration information can also be referred to as wake-up signal configuration information.

[0114] In some embodiments, the terminal may attempt to receive first information of the first cell based on the first condition.

[0115] In some embodiments, the first condition may include at least one of the following:

[0116] The terminal is in a non-connected state, wherein the non-connected state includes at least one of the following: an idle state and an inactive state;

[0117] The terminal obtains indication information for indicating that the first information is transmitted in the first cell. For example, the indication information may include an information element (IE) ssb-SubcarrierOffset (for example, which can be translated as a synchronized broadcast signal block subcarrier offset);

[0118] The terminal sends a request message to the network device, wherein the request message is used to request the network device to send the first information;

[0119] The terminal is in a connected state and receives a system information change indication;

[0120] The terminal is in a connected state, and the T311 timer (the specific meaning can be referred to in the relevant art, and the present disclosure does not elaborate on its meaning here) is running;

[0121] The terminal is in a connected state and has not obtained a valid version of system information, or has not obtained valid system information (such as SIB1) during a current modification.

[0122] The following uses several embodiments to exemplify the content of the first configuration information and the method for determining the content of the first configuration information.

[0123] In some embodiments, the first configuration information includes at least one of the following:

[0124] Time domain resource information;

[0125] Frequency domain resource information;

[0126] Request information.

[0127] For example, the time domain resource information in the first configuration information may indicate the time domain resource for the terminal to send the request information, and the terminal may send the request information to the network device on the time domain resource indicated by the time domain resource information. The granularity of the time domain resource may be a time domain unit, wherein the time domain unit includes at least one of the following: frame, subframe, time slot, and symbol.

[0128] For example, the frequency domain resource information in the first configuration information may indicate the frequency domain resource on which the terminal sends the request information, and the terminal may send the request information to the network device on the frequency domain resource indicated by the frequency domain resource information. The granularity of the frequency domain resource may be a frequency domain unit, wherein the frequency domain unit includes at least one of the following: Hertz (Hz), megahertz (MHz), resource block (RB), and resource element (RE).

[0129] In some embodiments, the resource information is determined based on at least one of the following:

[0130] The resources indicated by the downlink information;

[0131] The resources indicated by the downlink information, and the mapping relationship between the resources and the resource range;

[0132] The downlink information indicates a resource among multiple candidate resources.

[0133] For example, the downlink information may be a resource actually used to send the request information, and the terminal may send the request information on the resource indicated by the downlink information.

[0134] For example, downlink information can indicate resources, but the indicated resources are relative resources and need to be mapped to a specific resource range to determine the resources actually used to send the request information. The resource range includes but is not limited to carriers and bandwidth parts (BandWidth Part, BWP).

[0135] In this case, the downlink information can indicate resources (e.g., relative resources), and can also indicate a mapping relationship between resources and resource ranges. Alternatively, the terminal can predetermine (e.g., based on a protocol agreement, or based on a network device indication) the mapping relationship between resources and resource ranges. The terminal can then map the resources indicated by the downlink information to the resource range based on the mapping relationship, thereby determining the absolute time domain resources. For example, if the resources of the downlink information are one or more indexes, and the frequency domain resource range is a BWP, which includes multiple RBs, the terminal can determine, based on the mapping relationship, the RB corresponding to the index indicated by the downlink information in the BWP as the resource actually used to send the request information.

[0136] For example, the downlink information may indicate a resource among multiple candidate resources. For example, the terminal may predetermine (e.g., based on a protocol agreement or based on a network device indication) multiple candidate resources and an index of each candidate resource. The downlink information may indicate an index of a resource, and the terminal may determine, among the multiple candidate resources, that the candidate resource corresponding to the index indicated by the downlink information is the resource actually used to send the request information.

[0137] In some embodiments, the specific frequency domain unit can be determined based on the sub-carrier spacing (SCS) of the uplink bandwidth (UL band) used to send the request information, or it can be based on the SCS of the downlink bandwidth (DL band) where the SSB received by the terminal is located.

[0138] For example, the request information in the first configuration information may indicate the type of request information sent by the terminal to the network device, and the terminal may send request information of this type to the network device.

[0139] The following describes specific request information through several embodiments.

[0140] In some embodiments, the request information includes at least one of the following:

[0141] Preamble;

[0142] Physical Uplink Shared Channel (PUSCH).

[0143] Physical Uplink Control Channel (PUCCH).

[0144] In some embodiments, in response to the request information being a preamble, the network device may further indicate to the terminal at least one of the following:

[0145] The index of the preamble (index);

[0146] Random Access Occasion (RO) for sending preamble;

[0147] The correspondence between random access timing and SSB;

[0148] The transmit power of the preamble.

[0149] In some embodiments, when the request information is a preamble, in order to successfully send the preamble, the terminal can determine at least one piece of information such as the preamble index, the RO used to send the preamble, the correspondence between the RO and the SSB, and the preamble transmission power based on the network device indication. As for the information that the terminal fails to determine based on the network device indication, the terminal can determine it according to a predefined method (such as a protocol agreement).

[0150] In some embodiments, the preamble serving as the request information may correspond to the cell in which the terminal sends the request information. For example, the terminal needs to send the request information to the network device in the first cell, and the preamble corresponding to the first cell, such as preamble#1, may be determined. Then, preamble#1 may be sent to the network device in the first cell. The network device may determine, based on the received preamble#1, that the terminal requests the network device to send the first information.

[0151] The correspondence between the preamble and the cell may be agreed upon by a protocol or indicated by a network device, and the present disclosure does not limit this.

[0152] In some embodiments, in response to the request information being a PUSCH, the network device may further indicate to the terminal at least one of the following:

[0153] PUSCH modulation and coding scheme (MCS);

[0154] PUSCH transmit power.

[0155] In some embodiments, when the request information is carried in the PUSCH, in order to successfully send the PUSCH, the terminal can determine at least one piece of information such as the MCS of the PUSCH, the transmission power of the PUSCH, etc. based on the network device indication. As for the information that the terminal fails to determine based on the network device indication, the terminal can determine it according to a predefined method (such as protocol agreement).

[0156] In some embodiments, when the terminal carries the request information to the network device via the PUSCH, the terminal may also carry the information of the first cell in the PUSCH, and instruct the network device via the information of the first cell in the PUSCH. The request information specifically requests the network device to send the first information in the first cell. The network device may accordingly choose to send the first information in the first cell.

[0157] In some embodiments, the request information may include a combination of a preamble and a PUSCH, such as a portion of the request information being in the preamble and another portion being in the PUSCH. For example, in this case, the preamble may be included in random access message 1 (Msg1) and the PUSCH may be included in random access message 3 (Msg3).

[0158] In some embodiments, in response to the request information being a PUCCH, the network device may further indicate to the terminal at least one of the following:

[0159] The PUCCH format is determined based on network device instructions.

[0160] The PUCCH resource is determined based on the network device indication.

[0161] The PUCCH resource set (resource set) is determined based on the network device indication.

[0162] In some embodiments, when the request information is carried in the PUCCH, in order to successfully send the PUCCH, the terminal can determine at least one piece of information such as the PUCCH format, PUSCH resource, PUSCH resource set based on the network device indication. As for the information that the terminal fails to determine based on the network device indication, the terminal can determine it according to a predefined method (such as protocol agreement).

[0163] Several embodiments are used below to exemplify several types of first indication information.

[0164] In some embodiments, the downlink information includes at least one of the following: downlink control information DCI; physical downlink shared information PDSCH; system information (SI); media access control layer control element (MAC CE); radio resource control (RRC) signaling.

[0165] In some embodiments, the downlink control information includes at least one of the following: DCI 1_0 scrambled by a system information radio network temporary identifier (SI-RNTI); DCI 1_0 scrambled by a newly defined RNTI.

[0166] It should be noted that the embodiment of the present invention uses DCI1_0 as an example to illustrate the solution of the present invention. However, the solution of the present invention is not limited to DCI1_0 and can also be applied to other DCIs, and the present invention does not limit this.

[0167] It should be noted that DCI 1_0 scrambled by RNTI is not limited to DCI 1_0 scrambled by SI-RNTI, but may also include other traditional RNTIs, such as Paging Temporary Indentifier (P-RNTI), or newly introduced RNTIs, such as DCI scrambled by NES-RNTI. The present disclosure is not limited to this. The following embodiments mainly illustrate the technical solution of the present disclosure using DCI 1_0 scrambled by SI-RNTI.

[0168] In some embodiments, DCI 1_0 in which the indication information includes SI-RNTI scrambling is taken as an example.

[0169] In some embodiments, SI-RNTI scrambled DCI 1_0 may schedule system information, such as SIB1, SIBx (SIBs other than SIB1).

[0170] In some embodiments, the SI-RNTI scrambled DCI 1_0 may include at least one of the following information:

[0171] Frequency Domain Resource Allocation (FDRA) information field;

[0172] Time Domain Resource Allocation (TDRA) information domain;

[0173] Virtual Resource Block (VRB) to Physical Resource Block (PRB) mapping (VRB-to-PRB mapping) information field;

[0174] MCS information domain;

[0175] Redundancy Version (RV) information field;

[0176] System information indicator information field.

[0177] For example, the number of bits in the FDRA information field is in, Indicates the number of RBs occupied by the control resource set CORESET#0.

[0178] For example, the TDRA information field can occupy 4 bits. Considering that the TDRA table for scheduling SIB1 cannot be configured through RRC signaling, the application table is determined in a predefined manner. The following default A / B / C correspond to tables 5.1.2.1.1-2 (A for normal CP), 5.1.2.1.1-3 (A for normal ECP), 5.1.2.1.1-4 and 5.1.2.1.1-5, respectively. The TDRA indicates one row of the application table.

[0179] For example, Table 5.1.2.1.1-1: PDSCH time domain resource allocation applicable to DCI 1_0, 1_1, and 4_0 is shown in Table 1 below:

[0180] Table 1

[0181] For example, the VRB-to-PRB mapping information field may occupy 1 bit.

[0182] For example, the MCS information field may occupy 5 bits and may indicate one row in Table 5.1.4.1-1 specified in the protocol TS 38.214.

[0183] The RV information field may occupy 2 bits.

[0184] The system information indication information field may occupy 1 bit. For example, Table 7.3.1.2.1-2: System Information Indication Information Field is shown in Table 2 below:

[0185] Table 2

[0186] Among them, SIBs other than SIB1 and posSIBs are carried in the system information message.

[0187] In addition, the SI-RNTI scrambled DCI 1_0 may further include reserved bits. For example, for shared channel access in the FR1 or FR2 frequency band, the reserved bits may be 17 bits, and in other cases, the reserved bits may be 15 bits.

[0188] In an embodiment of the present disclosure, when the first configuration information is indicated to the first terminal through the SI-RNTI-scrambled DCI 1_0, the SI-RNTI-scrambled DCI 1_0 described in the above example can be multiplexed.

[0189] In some embodiments, the first bit in DCI 1_0 is used to indicate one of the following: DCI 1_0 is used to indicate the first configuration information; DCI 1_0 is used to schedule the system information block SIB; whether the PDSCH scheduled by DCI 1_0 is used to indicate the first configuration information.

[0190] As can be seen from the previous embodiments, traditional SI-RNTI-scrambled DCI 1_0 can schedule a SIB (e.g., SIB1 or other SIBs). However, according to the embodiments of the present disclosure, the function of SI-RNTI-scrambled DCI 1_0 is expanded to also indicate the first configuration information. Therefore, it is necessary for the terminal to clearly understand the function of SI-RNTI-scrambled DCI 1_0.

[0191] In this embodiment, the first bit in the SI-RNTI scrambled DCI 1_0 can be used to indicate the function of the SI-RNTI scrambled DCI 1_0, for example, to indicate that the SI-RNTI scrambled DCI 1_0 is used to indicate the first configuration information, or to indicate that the SI-RNTI scrambled DCI 1_0 is used to schedule the SIB, or to indicate whether the PDSCH scheduled by the SI-RNTI scrambled DCI 1_0 is used to indicate the first configuration information.

[0192] It should be noted that the "whether the PDSCH scheduled by DCI1_0 is used to indicate the first configuration information" described in the embodiments of the present disclosure (such as the above embodiments and subsequent embodiments) may include at least one of the following: whether the PDSCH scheduled by DCI 1_0 with SI-RNTI scrambling is used to carry the first configuration information; whether the PDSCH scheduled by DCI 1_0 with SI-RNTI scrambling is used to indicate the relevant information of the first configuration information (such as the identifier, index, etc. of the first configuration information). The relevant information of the first configuration information is associated with the first configuration information and can be used by the terminal to determine the first configuration information.

[0193] For example, the first bit in the SI-RNTI scrambled DCI 1_0 may be one bit (for example, the first bit or the last bit in the reserved bits) or multiple bits in the SI-RNTI scrambled DCI 1_0, or may be the first bit or the last bit in the SI-RNTI scrambled DCI 1_0.

[0194] For example, the indication value of the first bit is 1, which may indicate that the SI-RNTI-scrambled DCI 1_0 is used to indicate the first configuration information. The terminal may determine the first configuration information based on one or more bits (except the first bit) in the SI-RNTI-scrambled DCI 1_0, for example, based on all information fields (except the first bit) in the SI-RNTI-scrambled DCI 1_0.

[0195] For example, the indication value of the first bit is 0, which can indicate that the SI-RNTI-scrambled DCI 1_0 is used to schedule SIB (for example, carrying SI), and the terminal can carry SI based on the SI-RNTI-scrambled DCI 1_0. Furthermore, the terminal can determine one or more SIBs scheduled by the SI-RNTI-scrambled DCI 1_0 according to the System information indicator information field in the SI-RNTI-scrambled DCI 1_0, such as SIB1 or other SIBs other than SIB1.

[0196] In some embodiments, the first bit in DCI 1_0 and the system information indication field in DCI 1_0 are used to indicate one of the following:

[0197] The DCI 1_0 is used to indicate the first configuration information;

[0198] DCI 1_0 is used to indicate the first configuration information and is used to schedule SIB1;

[0199] DCI 1_0 is used to indicate the first configuration information and is used to schedule SIBx, where x is an integer greater than 1;

[0200] DCI 1_0 is used to schedule SIB1;

[0201] DCI 1_0 is used to schedule SIBx;

[0202] Whether the PDSCH scheduled by DCI 1_0 is used to indicate the first configuration information.

[0203] As can be seen from the previous embodiments, traditional SI-RNTI-scrambled DCI 1_0 can schedule SIB1 or other SIBs other than SIB1, such as SIBx, where x is an integer greater than 1. However, according to the embodiments of the present disclosure, the functionality of SI-RNTI-scrambled DCI 1_0 is expanded to also indicate first configuration information. Therefore, it is necessary for the terminal to clearly understand the functionality of SI-RNTI-scrambled DCI 1_0.

[0204] In this embodiment, the first bit in the SI-RNTI scrambled DCI 1_0 and the system information indication information field in the SI-RNTI scrambled DCI 1_0 can be used to indicate the function of the SI-RNTI scrambled DCI 1_0, for example, it can indicate that the SI-RNTI scrambled DCI 1_0 is used to indicate the first configuration information and is used to schedule SIB1, or indicate that the SI-RNTI scrambled DCI 1_0 is used to indicate the first configuration information and is used to schedule SIBx, or indicate that the SI-RNTI scrambled DCI 1_0 is used to schedule SIB1, or indicate that the SI-RNTI scrambled DCI 1_0 is used to schedule SIBx, or indicate whether the PDSCH scheduled by the SI-RNTI scrambled DCI 1_0 is used to indicate the first configuration information.

[0205] For example, the first bit in the SI-RNTI scrambled DCI 1_0 may be one bit (for example, the first bit or the last bit in the reserved bits) or multiple bits in the SI-RNTI scrambled DCI 1_0, or may be the first bit or the last bit in the SI-RNTI scrambled DCI 1_0.

[0206] For example, if the indication value of the first bit is 1, and the terminal determines that the SI-RNTI-scrambled DCI 1_0 carries the first configuration information, then parsing the System Information Indicator field is unnecessary. In this case, part or all of the information field in the SI-RNTI-scrambled DCI 1_0 can be refarmed, for example, to indicate the first configuration information. Exemplarily, the terminal can read the first configuration information based on all bits carried by DCI 1_0 except the first bit.

[0207] For example, if the indication value of the first bit is 0, and the terminal determines that the SI-RNTI-scrambled DCI 1_0 is not used to carry the first configuration information, then the terminal can determine that the SI-RNTI-scrambled DCI 1_0 is still used to schedule the SIB, and can then parse the System Information Indicator field to determine whether to schedule SIB1 or SIBn. Exemplarily, SIBn is a SIB other than SIB1.

[0208] For example, if the indication value of the first bit is 1 and the indication value of the System Information Indicator field is 0, the terminal determines that the SI-RNTI-scrambled DCI 1_0 is used to schedule SIB1 and carries the first configuration information. The terminal can then determine the first configuration information based on one or more bits (except the first bit) in the SI-RNTI-scrambled DCI 1_0, for example, based on all information fields (except the first bit) in the SI-RNTI-scrambled DCI 1_0.

[0209] For example, if the indication value of the first bit is 1 and the indication value of the System Information Indicator field is 1, the terminal determines that the SI-RNTI-scrambled DCI 1_0 is used to schedule SIBx and carries the first configuration information. The terminal can then determine the first configuration information based on one or more bits (except the first bit) in the SI-RNTI-scrambled DCI 1_0, for example, based on all information fields (except the first bit) in the SI-RNTI-scrambled DCI 1_0.

[0210] For example, the indication value of the first bit is 0, and the indication value of the System information indicator field is 0, and the terminal determines that the SI-RNTI-scrambled DCI 1_0 is used to schedule SIB1 and does not carry the first configuration information.

[0211] For example, the indication value of the first bit is 0, and the indication value of the System information indicator field is 1, and the terminal determines that the SI-RNTI-scrambled DCI 1_0 is used for scheduling SIBx and does not carry the first configuration information.

[0212] In some embodiments, the SI-RNTI scrambled DCI 1_0 may carry first configuration information, and the first configuration information may include time domain resources for sending request information, and may also include frequency domain resources for sending request information.

[0213] For example, the first configuration information in the SI-RNTI-scrambled DCI 1_0 includes the time domain resources used to send the request information. In some embodiments, the terminal may predetermine multiple time domain resource patterns, and the SI-RNTI-scrambled DCI 1_0 may indicate a time domain resource pattern index. The terminal may determine the time domain resource pattern used to send the request information from the multiple time domain resource patterns based on the time domain resource pattern index indicated by the SI-RNTI-scrambled DCI 1_0.

[0214] The time domain resource pattern may indicate which secondary time domain units in the primary time domain unit are used to send the request information. For example, the primary time domain unit includes a time slot, and the secondary time domain unit includes a symbol. For example, the primary time domain unit includes a subframe, and the secondary time domain unit includes a time slot. For example, the primary time domain unit includes a frame, and the secondary time domain unit includes a subframe.

[0215] It should be noted that the multiple time domain resource patterns and corresponding indexes predetermined by the terminal can be determined based on a predefined method (such as a protocol agreement) or can be determined based on network device instructions, and the present disclosure does not limit this.

[0216] For example, the first configuration information in the SI-RNTI-scrambled DCI 1_0 includes frequency domain resources for sending the request information. In some embodiments, the terminal may predetermine multiple frequency domain resource patterns, and the SI-RNTI-scrambled DCI 1_0 may indicate a frequency domain resource pattern index. The terminal may determine the time domain resource pattern for sending the request information from the multiple frequency domain resource patterns based on the frequency domain resource pattern index indicated by the SI-RNTI-scrambled DCI 1_0.

[0217] The time domain resource pattern may indicate which secondary frequency domain units in the primary frequency domain unit are used to send the request information. For example, the primary frequency domain unit includes RBs, and the secondary frequency domain unit includes REs. For example, the primary frequency domain unit includes a frequency band, and the secondary frequency domain unit includes a bandwidth part (BWP).

[0218] It should be noted that the multiple frequency domain resource patterns and corresponding indexes predetermined by the terminal can be determined based on a predefined method (such as protocol agreement) or can be determined based on network device instructions, and the present disclosure does not limit this.

[0219] For example, the first configuration information in the SI-RNTI-scrambled DCI 1_0 may also include an MCS for sending the request information. In some embodiments, the terminal may predetermine multiple MCS patterns, and the SI-RNTI-scrambled DCI 1_0 may indicate an MCS pattern index. The terminal may determine the MCS pattern for sending the request information from the multiple MCS patterns based on the MCS pattern index indicated by the SI-RNTI-scrambled DCI 1_0.

[0220] It should be noted that the multiple MCS patterns and corresponding indexes predetermined by the terminal can be determined based on a predefined method (such as protocol agreement) or can be determined based on network device instructions, and the present disclosure does not limit this.

[0221] In some embodiments, the resources of DCI 1_0 are blindly detected based on at least one of the following: search space Searchspace#0; control resource set CORESET#0.

[0222] The first configuration information in the SI-RNTI-scrambled DCI 1_0 is used by the terminal to send a request to the network device. The terminal needs to send the request to the network device because it has failed to obtain the first information. If the first information cannot be obtained, for example, if the first information includes SIB1, the terminal cannot determine other search spaces and core sets capable of transmitting DCI 1_0, except for Searchspace#0 and CORESET#0.

[0223] Therefore, in this case, the network device can transmit SI-RNTI-scrambled DCI 1_0 in Searchspace#0 and / or CORESET#0. Accordingly, even if the terminal fails to obtain the first information, the terminal can determine Searchspace#0 and / or CORESET#0, and then blindly detect SI-RNTI-scrambled DCI 1_0 based on Searchspace#0 and / or CORESET#0, so that the terminal can successfully blindly land SI-RNTI-scrambled DCI 1_0.

[0224] In some embodiments, the first configuration information may be indicated by DCI 1_0 scrambled by a newly defined RNTI.

[0225] In some embodiments, the newly defined RNTI-scrambled DCI 1_0 may carry first configuration information, and the first configuration information may include time domain resources for sending request information, and may also include frequency domain resources for sending request information.

[0226] For example, the first configuration information in the newly defined RNTI-scrambled DCI 1_0 includes the time domain resources used to send the request information. In some embodiments, the terminal may predetermine multiple time domain resource patterns, and the newly defined RNTI-scrambled DCI 1_0 may indicate a time domain resource pattern index. The terminal may determine the time domain resource pattern used to send the request information from the multiple time domain resource patterns based on the time domain resource pattern index indicated by the newly defined RNTI-scrambled DCI 1_0.

[0227] The time domain resource pattern may indicate which secondary time domain units in the primary time domain unit are used to send the request information. For example, the primary time domain unit includes a time slot, and the secondary time domain unit includes a symbol. For example, the primary time domain unit includes a subframe, and the secondary time domain unit includes a time slot. For example, the primary time domain unit includes a frame, and the secondary time domain unit includes a subframe.

[0228] It should be noted that the multiple time domain resource patterns and corresponding indexes predetermined by the terminal can be determined based on a predefined method (such as a protocol agreement) or can be determined based on network device instructions, and the present disclosure does not limit this.

[0229] For example, the first configuration information in the newly defined RNTI-scrambled DCI 1_0 includes frequency domain resources for sending the request information. In some embodiments, the terminal may predetermine multiple frequency domain resource patterns, and the newly defined RNTI-scrambled DCI 1_0 may indicate a frequency domain resource pattern index. The terminal may determine the time domain resource pattern for sending the request information from the multiple frequency domain resource patterns based on the frequency domain resource pattern index indicated by the newly defined RNTI-scrambled DCI 1_0.

[0230] The time domain resource pattern may indicate which secondary frequency domain units in the primary frequency domain unit are used to send the request information. For example, the primary frequency domain unit includes RBs, and the secondary frequency domain unit includes REs. For example, the primary frequency domain unit includes a frequency band, and the secondary frequency domain unit includes a bandwidth part (BWP).

[0231] It should be noted that the multiple frequency domain resource patterns and corresponding indexes predetermined by the terminal can be determined based on a predefined method (such as protocol agreement) or can be determined based on network device instructions, and the present disclosure does not limit this.

[0232] For example, the first configuration information in the newly defined RNTI-scrambled DCI 1_0 may also include an MCS for sending the request information. In some embodiments, the terminal may predetermine multiple MCS patterns, and the newly defined RNTI-scrambled DCI 1_0 may indicate an MCS pattern index. The terminal may determine the MCS pattern for sending the request information from the multiple MCS patterns based on the MCS pattern index indicated by the newly defined RNTI-scrambled DCI 1_0.

[0233] It should be noted that the multiple MCS patterns and corresponding indexes predetermined by the terminal can be determined based on a predefined method (such as protocol agreement) or can be determined based on network device instructions, and the present disclosure does not limit this.

[0234] In some embodiments, the downlink information used to indicate the first configuration information to the terminal may include, in addition to the downlink control information in the above embodiments, system information (SI). For example, the system information may indicate the first configuration information to one or more terminals. The indicated first configuration information may be applicable to one cell at the same time, or may be applicable to multiple cells at the same time, that is, the terminal may send request information in any of the multiple cells based on the first configuration information.

[0235] For example, the network device can indicate the first configuration information to the terminal through the system information in the first cell. The first configuration information can be used by the terminal to send request information in the first cell. Then the network device can monitor the request information sent by the terminal according to the first configuration information in the first cell.

[0236] For example, the network device can indicate the first configuration information to the terminal through the system information in the first cell. The first configuration information can be used by the terminal to send request information in the second cell. Then the network device can monitor the request information sent by the terminal according to the first configuration information in the second cell.

[0237] For example, the network device may indicate first configuration information to the terminal through system information in the first cell. The first configuration information may be used by the terminal to send request information in the first cell. The request information may request the network device to send first information in the second cell.

[0238] Among them, if the first cell and the second cell are cells of the same network device, after the network device receives the request information in the first cell, it can choose to send the first information in the second cell. If the first cell and the second cell are cells of different network devices, then after the network device of the first cell receives the request information in the first cell, it can send a request to the network device of the second cell (for example, forward the request information to the network device of the second cell) to request the network device of the second cell to send the first information in the second cell. The network device of the second cell can choose to send the first information in the second cell based on the request sent by the network device of the first cell.

[0239] In some embodiments, the first configuration information is used by the terminal to send a request message to the first network device, and the request message is used to request other network devices to send the first information; or, the first configuration information is used by the terminal to send a request message to other network devices, and the request message is used to request other network devices to send the first information; or, the first configuration information is used by the terminal to send a request message to the first network device, and the request message is used to request the first network device to send the first information.

[0240] In some embodiments, the first configuration information may be sent by the first network device to the terminal. When the first information of the first network device is in an on-demand state and the terminal needs to obtain the first information of the first network device, the terminal may send a request message to the first network device based on the first configuration information, where the request message is used to request the first network device to send the first information.

[0241] In this case, the first network device may choose to send the first information based on the request information sent by the terminal, so as to ensure that the terminal can receive the first information sent by other network devices.

[0242] In some embodiments, the first configuration information may be sent by the first network device to the terminal. When the first information of the other network device is in an on-demand state and the terminal needs to obtain the first information of the other network device, the terminal may send a request message to the second network device based on the first configuration information, where the request message is used to request the other network device to send the first information.

[0243] In this case, the first configuration information sent by the first network device to the terminal can be used by the terminal to send request information to other network devices. After receiving the request information, the other network devices can choose to send the first information to ensure that the terminal can receive the first information sent by the other network devices.

[0244] For example, the first network device and the other network device are different network devices. In the embodiments of the present disclosure, the network device may refer to a base station or a cell. Taking the first network device as a first cell and the other network devices as a second cell as an example, the first cell may be a cell that normally sends the first information, for example, sends the first information based on the configuration of the first information, and the second cell may be a cell that stops sending the first information, for example, the first information of the second cell is in an on-demand state. In this case, the first cell may be referred to as an anchor cell, and the second cell may be referred to as a non-anchor cell.

[0245] In some embodiments, the first configuration information may be sent by the first network device to the terminal. When the first information of the other network device is in an on-demand state and the terminal needs to obtain the first information of the other network device, the terminal may send a request message to the first network device based on the first configuration information, where the request message is used to request the other network device to send the first information.

[0246] In this case, the first network device can determine, based on the request information sent by the terminal, that the terminal requests other network devices to send the first information, so that the first network device can send a request to other network devices to request other network devices to send the first information, so as to ensure that the terminal can receive the first information sent by other network devices.

[0247] For example, the first network device and the other network device are different network devices. In the embodiments of the present disclosure, the network device may refer to a base station or a cell. Taking the first network device as a first cell and the other network devices as a second cell as an example, the first cell may be a cell that normally sends the first information, for example, sends the first information based on the configuration of the first information, and the second cell may be a cell that stops sending the first information, for example, the first information of the second cell is in an on-demand state. For example, the first cell may be referred to as an anchor cell, and the second cell may be referred to as a non-anchor cell.

[0248] In some embodiments, the first configuration information may be sent by the first network device to the terminal in the first cell, and the first configuration information may be applicable to multiple cells at the same time, that is, the terminal may send request information in any of the multiple cells according to the first configuration information.

[0249] For example, the first configuration information may include resource information, where the resource information is used to indicate resources. The first configuration information may also include a mapping relationship between resources and resource ranges, or the terminal may predetermine (e.g., based on a protocol agreement or based on a network device indication) the mapping relationship between resources and resource ranges. The resource range includes, but is not limited to, a carrier and an uplink bandwidth part (UL BWP). For example, the uplink bandwidth part may be an initial uplink bandwidth part (initial UL BWP).

[0250] Exemplarily, the terminal may determine the resource range information of the current cell based on SIB1 or RRC signaling, for example, obtain the carrier or initial UL BWP information of the current cell through SIB1.

[0251] In one possible implementation, the terminal obtains the corresponding first configuration information in the first cell. If the terminal sends the corresponding SIB1 request in the first cell to request other cells to transmit the corresponding SIB1, the terminal can parse the corresponding FDRA and / or TDRA based on the UL BWP where the first cell is located, thereby obtaining the time-frequency domain resources for the transmission request information and transmitting the request information on the corresponding resources.

[0252] In another possible implementation, the terminal obtains the corresponding first configuration information in the first cell. If the terminal needs to send request information in other cells to request SIB1 transmission of the other cells, the terminal may determine the UL BWP of the terminal based on the SIB1 and / or RRC signaling of the other cells, and parse the corresponding FDRA and / or TDRA based on the BWP to obtain the time-frequency domain resources of the request information and transmit the request information on the corresponding resources.

[0253] When the first information in the first cell is in an on-demand state, if the terminal needs to obtain the first information in the first cell, the terminal can determine resource range #1 of the first cell and map the resources indicated by the first configuration information to resource range #1, thereby determining resource #1 for sending the request information in the first cell. Then, in the first cell, the terminal can send the request information on resource #1. For example, the request information can request the network device to send the first information in the first cell.

[0254] When the first information in the second cell is in an on-demand state, if the terminal needs to obtain the first information in the second cell, the terminal can determine resource range #2 of the second cell and map the resources indicated by the first configuration information to resource range #2, thereby determining resource #2 for sending the request information in the second cell. Then, in the second cell, the terminal can send request information on resource #2. For example, the request information can request the network device to send the first information in the second cell.

For example, step S201 may be implemented as an independent embodiment, step S202 may be implemented as an independent embodiment, and steps S201+S202 may be implemented as independent embodiments, but are not limited thereto.

[0296] In some embodiments, the first configuration information is used by the terminal to send a request message to the first network device, and the request message is used to request the other network device to send the first information; or, the first configuration information is used by the terminal to send a request message to other network devices, and the request message is used to request the other network device to send the first information; or, the first configuration information is used by the terminal to send a request message to the first network device, and the request message is used to request the first network device to send the first information.

[0299] In some embodiments, the request information includes at least one of the following: a preamble; a physical uplink shared channel PUSCH; and a physical uplink control channel PUCCH.

[0300] In some embodiments, the first information includes at least one of the following: a system information block SIB1; a synchronization broadcast signal block SSB.

[0301] The second aspect and the optional implementation of the optional embodiment of the second aspect can be referred to the optional implementation in the embodiment shown in Figure 2 and other related parts in the embodiment involved in Figure 2, which will not be repeated here.

[0302] In some implementations, the Network Energy Saving (NES) topic has been researched to reduce energy consumption in base stations and the network. For example, during the research phase, NES technologies in the time, frequency, spatial, and power domains were thoroughly evaluated. During the standards phase, some technologies in the time, spatial, and power domains were standardized.

[0303] In NR, the time domain location of SSB / SIB1 transmission opportunities is semi-statically configured. The periodic transmission of common signals (SSB / SIB1 / cell-common PDCCH) will limit the base station's use of (deeper) sleep mode to save energy. Therefore, time domain technology achieves energy saving by limiting the transmission / reception of common signals and increasing the base station's sleep time. In the current protocol, SSB and SIB1 are periodically transmitted at a determined time-frequency resource location according to a period predefined by the protocol and / or configured by the network side.

[0304] In some embodiments, regarding SSB: an SSB occupies 4 consecutive OFDM symbols in the time domain, including PSS, SSS and PBCH. The NR system supports 5 SSB time domain transmission cases, namely case A-case E. The time domain pattern of the case depends on factors such as the SCS of the SSB, the operating frequency, the TDD / FDD standard, etc. Different SSB cases correspond to the number of SSBs in an SSB burst and the time domain resource positions occupied in the burst. The duration of the SSB burst is 5ms. Typically, the transmission period of the SSB is 20ms. Furthermore, the base station can configure the transmission period and time domain pattern of the SSB through the relevant information carried in SIB1. The maximum transmission period of the SSB is 160ms.

[0305] In some embodiments, regarding SIB1: SIB1 is scheduled through DCI format 1-0 transmitted in Type0-CSS. The SS related to Type-0 CSS and the corresponding time-frequency resource location can be indicated by MIB, or configured through SIB1 or RRC signaling. Its transmission period and time-frequency resource location depend on the SSB / SIB1 multiplexing pattern and the indication information carried in the DCI format 1-0 that schedules its transmission. The base station must send SIB1 periodically so that IDLE / INACTIVE UE and CONNECTED UE can obtain system information in a timely manner. In addition to the resource overhead caused by the SIB1 transmission itself, the CORESET#0 or other CORESET used for the PDCCH transmission that schedules the SIB1 transmission also occupies considerable time domain resources in the time domain.

[0306] On-demand SSB / SIB1 technology in the time domain is one of the important candidate technologies. In on-demand SSB / SIB1 technology, SSB / SIB1 is no longer sent periodically, but is sent according to the needs of the UE.

[0307] The base station stops sending SSB / SIB1 periodically (is in NES state), or uses a more sparse time domain pattern to send SSB / SIB1. When the UE has SSB / SIB1 requirements, it will send a wake-up signal (WUS) to the base station.

[0308] After receiving the WUS signal, the base station sends SSB / SIB1 (enters the non-NES state) and stops sending SSB / SIB1 (returns to the NES state) after sending one or more SSB bursts, depending on the network service load, the number of resident terminals, the service type, the time period, etc.

[0309] Taking on-demand SIB1 as an example, to send a WUS signal that triggers SIB1 transmission, the terminal needs to obtain the corresponding WUS configuration. The WUS configuration includes the time-frequency domain information required for the terminal to send the WUS signal and WUS signal-related information. For example, one way for the terminal to obtain the WUS configuration is for the terminal to obtain the WUS configuration of the current cell in another cell, where the other cell is a cell that periodically transmits SIB1. The main motivation for this method is that in a cell that periodically transmits SIB1, the terminal can obtain WUS-related configuration based on system information.

[0310] In some embodiments, SIB1 is basic system information that determines whether a terminal can camp in the current cell. In an on-demand SIB1 cell, a terminal must send a WUS based on the WUS configuration to request SIB1 transmission. Therefore, the latency for a terminal to obtain the WUS configuration determines the latency for the terminal to camp in the on-demand SIB1 cell. To enable a terminal to obtain the corresponding WUS configuration as quickly as possible, one possible approach is to obtain the corresponding WUS configuration in the current cell (the on-demand SIB1 cell).

[0311] In another scenario, for example, in a remote mountainous area with wide coverage, the terminal may not be able to search for other cells through cell search. The terminal can only obtain the corresponding WUS configuration based on the current cell.

[0312] The current protocol defines an on-demand SI mechanism for requesting SIBn (n>1). The base station configures the time-frequency domain resources and request information for the on-demand request. Based on the configuration, the terminal sends the request information on the corresponding resources. The specific mechanism includes:

[0313] In some embodiments, the application conditions are: when si-BroadcastStatus is configured as notBroadcasting, and when SI-RequestConfig is configured, the demanded Msg1 resources are determined based on SI-RequestConfig; otherwise, the request information is carried based on msg 3, and the request information is defined based on the following RRCSystemInfoRequest.

[0314] In some embodiments, the introduction motivation is: the concept of Beam is introduced in NR. In order to support full coverage of the cell, the base station needs to broadcast system messages to Beams in different directions in different slots.

[0315] At high frequencies, the maximum number of beams is 64. Therefore, using a non-broadcast approach can save base station power consumption. On the other hand, if broadcasting is used, PDCCH resources must be reserved to schedule system messages; these resources cannot be used for scheduling other PDSCHs.

[0316] In some embodiments, the request method includes at least one of the following:

[0317] Msg 1 based (based on message 1): The specified preamble index is allocated through SI-RequestConfig, and the UE sends the corresponding PRACH to request the base station to send system information. The base station responds to the UE by sending MSG2. As long as the RAPID in MSG2 is consistent with the preamble index sent by the UE, it is considered that the base station has received the UE's request.

[0318] Msg 3 based: The terminal transmits the RRCSystemInfoRequest message via Msg 3. If, after transmitting the request message, the terminal successfully receives the Msg 4 request message transmitted by the base station and successfully completes the random access response, the base station is considered to have responded to the user request. Otherwise, the base station is considered to have not responded to the user request. For details on the corresponding RRCSystemInfoRequest IE and the parameters used to determine the Msg 3 resources, please refer to the relevant technologies and will not be elaborated here.

[0319] The process of sending a request for information (e.g., Request for on-demand system information) can be as follows:

[0320] The UE shall, while SDT procedure is not ongoing:

[0321] 1>if the UE is not a RedCap UE and if SIB1 includes si-SchedulingInfo containing si-RequestConfig and criteria to select normal uplink (if the terminal is not a reduced capability (RedCap) terminal, and when SIB1 includes si-SchedulingInfo containing si-RequestConfig and is used for normal link);

[0322] 2>trigger the lower layer to initiate the Random Access procedure on normal uplink using the PRACH preamble(s)and PRACH resource(s)in si-RequestConfig corresponding to the SI message(s)that the UE requires to operate within the cell,and for which si-BroadcastStatus is set to notBroadcasting (using the PRACH preamble and PRACH resources in si-RequestConfig, triggering the lower layer to initiate the random access procedure on the normal uplink, si-RequestConfig corresponds to the SI message required for the UE to operate within the cell, and for the SI message, si-BroadcastStatus is set to notBroadcasting);

[0323] 2>if acknowledgement for SI request is received from lower layers (if confirmation for SI request is received from lower layers):

[0324] 3>acquire the requested SI message(s),immediately (immediately obtain the requested SI message);

[0325] 1>else (otherwise):

[0326] 2>apply the default L1 parameter values ​​as specified in corresponding physical layer specifications except for the parameters for which values ​​are provided in SIB1 (apply the default L1 parameter values ​​specified in the corresponding physical layer specifications, except for the parameters for which values ​​are provided in SIB1);

[0327] 2>apply the default MAC Cell Group configuration (apply the default MAC cell group configuration);

[0328] 2>apply the timeAlignmentTimerCommon included in SIB1 (apply the timeAlignmentTimerCommand included in SIB1);

[0329] 2>apply the CCCH configuration (apply CCCH configuration);

[0330] 2>initiate transmission of the RRCSystemInfoRequest message with rrcSystemInfoRequest (use RRCSystemInfoRequest to start the transmission of the RRCSystemInfoRequest message);

[0331] 2>if acknowledgement for RRCSystemInfoRequest message with rrcSystemInfoRequest is received from lower layers:

[0332] 3>acquire the requested SI message(s),immediately (immediately obtain the requested SI message).

[0333] In some embodiments, the terminal sends a WUS to the base station, and requests the base station to send the downlink signal and / or signal through the indication information carried by the WUS. In this embodiment, the terminal carries the request information through WUS signaling. Taking the downlink signal / channel as SSB / SIB1 as an example, the process related to the embodiment of the present invention may include the following steps:

[0334] Step 1: The terminal obtains WUS configuration information;

[0335] Step 2: The terminal determines that the gNB is in SIB1off and the terminal needs SIB1;

[0336] Step 3: The terminal sends a WUS to the gNB.

[0337] Step 4: gNB determines WUS to request SIB1;

[0338] Step 5: gNB sends SIB1;

[0339] Step 6: The terminal confirms that SIB1 is received.

[0340] The following is an illustrative description of the technical solution of the present disclosure from the perspectives of the terminal side and the network device side.

[0341] In some embodiments, from the terminal side:

[0342] A terminal supporting network energy saving obtains a WUS configuration through at least one of the following indication information, and sends a WUS signal based on the configuration to request corresponding SIB1 transmission:

[0343] In some embodiments, a terminal supporting network energy saving receives a DCI and obtains a WUS configuration based on the DCI information field indication information:

[0344] The DCI is DCI 1_0 scrambled by SI-RNTI;

[0345] The terminal determines whether the DCI carries WUS configuration information based on one reserved bit of the SI-RNTI-scrambled DCI 1_0;

[0346] If the reserved bit indication is 1, the terminal determines that the DCI carries WUS configuration information. If the reserved bit indication is 0, the terminal determines that the DCI is used to schedule SIBs;

[0347] The reserved bit is the first or last bit in DCI 1_0 (SI-RNTI scrambled);

[0348] In some embodiments, the terminal determines whether the DCI carries WUS configuration information based on one reserved bit of the SI-RNTI-scrambled DCI 1_0 and the System Information Indicator information field:

[0349] If the reserved bit indication is 1 and the corresponding System information indicator information field indication is 0, the terminal determines that the DCI carries WUS configuration information and is used to schedule SIB1;

[0350] If the reserved bit indication is 1 and the corresponding System information indicator information field indication is 1, the terminal determines that the DCI carries WUS configuration information and is used to schedule SIBs (except SIB1);

[0441] Implementation scenarios related to the embodiments of the present invention include the following implementation scenario one, implementation scenario two, implementation scenario three, implementation scenario four, and implementation scenario five.

[0442] Implementation scenario 1:

[0443] The terminal obtains the corresponding WUS signaling configuration information based on cell 1, and when it needs to request the network device corresponding to cell 2 to send SSB / SIB1 on cell 2, it sends the corresponding WUS signaling request information of cell 1 on cell 1.

[0444] In this scenario, Cell 2 is a cell that transmits SSB / SIB1 in on-demand mode. For example, the cell may be referred to as a non-anchor cell. When the terminal needs to transmit SSB / SIB1, it needs to send corresponding SIB1 / SSB request information.

[0445] In this scenario, cell 1 may be a cell that normally sends SSB / SIB1. For example, the cell may be called an anchor cell.

[0446] The anchor cell can configure WUS signaling configurations for SIB1 / SSB requests of one or more other cells (eg, non-anchor cells) and also receive SIB1 / SSB request information corresponding to multiple non-anchor cells.

[0447] For example, the UE sends SIB1 / SSB request information to cell 2 on cell 1. After receiving the request information, the network device corresponding to cell 1 transmits the request information to the network device corresponding to cell 2. After receiving the request information, the network device corresponding to cell 2 can decide whether to send SSB and SIB1 as needed.

[0448] In one possible implementation, the cell corresponding to the request information can be determined based on a predefined method. For example, different cells are associated with different information. If the terminal requests SIB1 for cell 2, WUS signaling corresponding to cell 2 can be transmitted. The mapping relationship between the different information and cells can be determined based on a signaling indication or a predefined method.

[0449] After receiving the WUS signaling, the network device may also determine the corresponding associated cell based on the WUS signaling, thereby performing subsequent operations.

[0450] Implementation scenario 2:

[0451] The terminal obtains the configuration information of the corresponding WUS signaling based on cell 1, and sends the corresponding WUS request information of cell 2 on cell 2 when it needs to request the network device corresponding to cell 2 to send SIB1 on cell 2.

[0452] In this scenario, Cell 2 is a cell that transmits SSB / SIB1 in on-demand mode. For example, the cell may be referred to as a non-anchor cell. When the terminal needs to transmit SSB / SIB1, it needs to send corresponding SIB1 / SSB request information.

[0453] In this scenario, cell 1 may be a cell that normally sends SSB / SIB1. For example, the cell may be called an anchor cell.

[0454] The anchor cell may configure WUS signaling configurations for SIB1 / SSB requests of one or more other cells (eg, non-anchor cells).

[0455] Exemplarily, the UE obtains the corresponding WUS signaling configuration on cell 1, and based on the above configuration, sends the corresponding SIB1 / SSB request information on cell 2. After receiving the above request information, the network device corresponding to cell 2 can decide whether to send SSB / SIB1 as needed;

[0456] Implementation scenario three:

[0457] The terminal obtains the configuration information of the corresponding WUS signaling based on cell 2, and when it needs to request the network device corresponding to cell 2 to send SSB / SIB1 on cell 2, it sends the corresponding WUS request information of cell 2 on cell 2.

[0458] In this scenario, Cell 2 is the cell that transmits SSB / SIB1 in on-demand mode. Furthermore, Cell 2 needs to be configured with the corresponding PUCCH format#2 configuration information. When the terminal needs to transmit SIB1, it needs to send the corresponding SIB1 / SSB request information.

[0459] In this scenario, if the cell is in the SIB1on state, the network device transmits the corresponding SIB1 information, and the terminal can obtain the corresponding WUS configuration based on the corresponding SI information.

[0460] In this scenario, if the cell is in the SIB1off state and the network device stops transmitting the corresponding SIB1 information, Cell 2 may require the terminal to obtain the corresponding WUS configuration information before obtaining SIB1. Accordingly, the WUS configuration information needs to be determined through SSB (e.g., MIB) configuration or newly defined downlink common signaling.

[0461] In a possible implementation manner, a pattern of the WUS configuration information is determined based on a predefined manner, and the pattern may be determined based on the configuration information.

[0462] In a possible implementation manner, cell 2 determines one of the predefined patterns based on a signaling indication.

[0463] It is worth noting that before the UE obtains the SIB1 information, it cannot obtain the frequency domain information corresponding to the initial UL BWP. It can only obtain the frequency domain information of the SSB. The resource location of the WUS signaling may use the frequency domain information corresponding to the SSB as a reference location. For details, see Examples 1 and 2, which are not repeated here.

[0464] It is worth noting that before the UE obtains the SIB1 information, the UE cannot obtain the TDD-related configuration information and can only obtain the time domain information of the SSB. The time domain position of the WUS signaling may use the time domain position corresponding to the SSB as a reference position.

[0465] From the terminal's perspective, when the terminal determines that cell 2 is in SSB / SIB1off, the terminal determines WUS signaling configuration information based on pdcch-ConfigSIB1, or determines the pattern of the configuration information, and transmits WUS signaling request SSB / SIB1 transmission based on the configuration information.

[0466] Implementation scenario four:

[0467] The terminal determines the WUS signaling configuration information based on a predefined method, and sends the corresponding WUS request information of cell 2 on cell 2 when it needs to request the network device corresponding to cell 2 to send SIB1 on cell 2.

[0468] In this scenario, Cell 2 is the cell that transmits SSB / SIB1 in on-demand mode. Furthermore, Cell 2 needs to be configured with the corresponding WUS signaling configuration information. When the terminal needs to transmit SIB1, it needs to send the corresponding SIB1 / SSB request information.

[0469] In this scenario, Cell 2 may require the terminal to obtain the corresponding WUS signaling configuration information before obtaining SIB1. Accordingly, the terminal may need to determine the WUS signaling configuration information based on the SSB information corresponding to Cell 2. The specific configuration information is similar to the pattern in implementation scenario 3 and will not be repeated here.

[0470] Implementation scenario five:

[0471] The terminal obtains the corresponding WUS configuration based on cell 1, and the WUS configuration can be applied to cell 1 and cell 2 at the same time.

[0472] In one possible implementation, the terminal obtains the corresponding WUS signaling configuration information based on cell 1, and obtains the UL carrier and / or UL BWP information of the terminal based on the SIB1 information corresponding to cell 1, thereby determining the time-frequency domain resources for the terminal's WUS transmission on cell 1. In this scenario, the UE sends SIB1 / SSB request information for cell 2 on cell 1. After receiving the request information, the network device corresponding to cell 1 transmits the request information to the network device corresponding to cell 2. After receiving the request information, the network device corresponding to cell 2 can decide whether to send SSB and SIB1 as needed.

[0473] In one possible implementation manner, the network device corresponding to cell 2 responds to the request information and sends SIB1 based on cell 2. The terminal obtains SIB1 in cell 2 and determines the UL carrier and / or UL BWP information of the terminal based on SIB1. The terminal determines the time-frequency domain resources for WUS transmission of the terminal on cell 2 based on the WUS configuration obtained in cell 1 and the UL carrier and / or UL BWP information of the terminal; in this scenario, when cell 2 is in the SIB1off phase subsequently, when the UE needs to obtain the corresponding SIB1, the UE sends SIB1 / SSB request information for cell 2 on cell 2, and after receiving the request information, the network device corresponding to cell 2 passes the request information to the network device corresponding to cell 2. After receiving the request information, the network device corresponding to Cell 2 can decide whether to send SIB1 as needed;

[0474] In a possible implementation manner, the WUS configuration may be based on system information SI configuration, where the SI may be existing SIBn information, eg, SIB1, SIB2, ..., or newly introduced SIBn information.

[0475] Based on the above implementation scenario, the solution of the present invention mainly considers that the terminal obtains the corresponding WUS configuration in cell 2 and the terminal obtains the WUS configuration before SIB1, designs a corresponding solution, and indicates the corresponding WUS configuration through signaling design.

[0476] In some embodiments, the terminal receives the indication signaling and determines the WUS configuration information, where the WUS configuration information includes at least one of the following:

[0477] Time domain resources for terminals to transmit WUS signals

[0478] Frequency domain resources for terminals to transmit WUS signals

[0480] Time domain resources corresponding to the WUS information: the time domain location includes at least one of the following: a period of WUS transmission, and a first time unit in which the WUS is transmitted.

[0481] In some embodiments, the first time unit is determined based on one or more of the following: a frame, a subframe, a time slot, a symbol.

[0482] In some embodiments, the frequency domain resources corresponding to the WUS information include at least one of the following: the lowest frequency domain position of the WUS transmission, the frequency domain range where the WUS transmission is located. Exemplarily, the frequency domain resources are determined based on the first frequency domain unit.

[0483] In some embodiments, the first frequency domain unit is determined based on one or more of the following: Hz, MHz, RB, RE, NR-ARFCN, GSCN.

[0484] In some embodiments, the WUS signal includes one or more of the following: Preamble, PUSCH, Preamble and PUSCH.

[0485] In some embodiments, if the signal includes a preamble, the corresponding factor includes at least one of the following:

[0486] Preamble index;

[0487] RO where the Preamble is transmitted;

[0488] The correspondence between RO and SSB;

[0489] Preamble transmission power;

[0490] In some embodiments, if the signal includes a PUSCH, the corresponding factor includes at least one of the following:

[0491] MCS;

[0492] Transmission power.

[0493] It should be noted that the terminal receives the indication information and determines the WUS configuration. The indication information may be used to indicate the WUS configuration information, and the WUS configuration information is determined based on the above method.

[0494] The indication information may also be used to indicate one of a plurality of WUS patterns. The WUS pattern is determined based on a predefined or signaling indication manner, and the WUS pattern is defined based on the above-mentioned WUS configuration.

[0495] As described above, the WUS configuration information and / or WUS pattern is carried based on the indication information, and the indication information is defined based on the following embodiments.

[0496] Example 1:
