Description

Methods, apparatus, terminals, and network-side equipment for determining the location of system information resources

[0001] This disclosure claims priority to Chinese Patent Application No. 202510118663.1, filed with the Chinese Patent Office on January 24, 2025, entitled "Method, Apparatus, Terminal and Network-Side Device for Determining the Location of System Information Resources", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure relates to the field of communication technology, and in particular to a method, apparatus, terminal and network-side equipment for determining the location of system information resources. Background Technology

[0003] Network energy conservation research primarily discusses various technologies that help reduce the energy consumption of network devices from the perspectives of time domain, frequency domain, spatial domain, and power domain. In current New Radio (NR) systems, the Primary Synchronization Signal (PSS), Secondary Synchronization Signal (SSS), and Physical Broadcast Channel (PBCH) are time-division multiplexed to form a Synchronization Signal Block (SSB). For an initially accessed cell, network-side equipment periodically transmits the SSB, and the terminal completes synchronization and cell search processes based on these periodic SSBs. During cell search, the terminal needs to acquire the Master Information Block (MIB) and the Physical Downlink Shared Channel (PDSCH) of System Information Block 1 (SIB1) to determine the main information residing in the cell, such as time information, random access resources, and paging resources.

[0004] When a User Equipment (UE) receives a SIB1 PDSCH, the following process is required: receiving an SSB; receiving downlink control information (DCI) that schedules the SIB1 PDSCH; and receiving the SIB1 PDSCH. The network-side device needs to send time-domain and frequency-domain resource-related information for detecting this DCI in the PBCH's MIB, then send the DCI, and then send the SIB1 PDSCH scheduled for that DCI. This transmission can be time-division multiplexed, which is not conducive to the network device entering sleep mode and wastes network power. Summary of the Invention

Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0049] In describing the embodiments of this disclosure, some concepts used in the following description will first be explained.

[0050] I. Resource diagrams for NR SSB:

[0051] The PSS, SSS, and PBCH employ TDM (Time Division Multiplexing). Each SSB occupies four Orthogonal Frequency Division Multiplexing (OFDM) symbols, with the PSS and SSS each occupying one symbol, and the PBCH occupying two symbols. The symbol order of PSS, SSS, and PBCH is PSS-PBCH-SSS-PBCH. The bandwidth of the SSB is 20 Physical Resource Blocks (PRBs), the bandwidth of the PSS / SSS is 12 PRBs, and the bandwidth of the PBCH is 20 PRBs. The center frequencies of the PSS / SSS and PBCH are aligned. The demodulation reference signals (DMRS) of the PSS, SSS, PBCH, and PBCH within the SSB are mapped to time-domain and frequency-domain resources (time domain: symbols, frequency domain: subcarriers) as shown in Table 1.

[0052] Table 1: Mapping of PSS, SSS, PBCH, and PBCH DMRS in time-domain and frequency-domain resources.

[0053] II. PBCH and PBCH DMRS:

[0054] PBCH generation: 24 bits of Broadcast Control Channel (BCCH) information (including 23 bits of MIB) and 8 bits of physical layer information are used to obtain a 32-bit PBCH payload. This payload then undergoes interleaving, first scrambling, and Cyclic Redundancy Check (CRC) (24 bits) to generate a 56-bit PBCH payload. Polar coding, rate matching, second scrambling, and Quadrature Phase Shift Keying (QPSK) modulation are then performed to generate a 432-symbol PBCH sequence. The PBCH DMRS sequence occupies 144 symbols.

[0055] III. Contents of MIB Instructions

[0056] The fields carried by the MIB include one or more of the following:

[0057] System Frame Number (SFN): 10 bits in total. The MIB carries 6 of the 10 bits of the high-order bits, and the remaining 4 low-order bits of the SFN are transmitted in the PBCH transport block as part of the channel coding.

[0058] Subcarrier Spacing Common: The subcarrier spacing used in Remaining Minimum System Information (RMSI) / Message 2 (MSG2) / Message 4 (MSG4); the subcarrier spacing is 15kHz and 30kHz for subcarriers less than 6GHz, and 60kHz and 120kHz for subcarriers greater than 6GHz.

[0059] SSB Subcarrier Offset: Represents the frequency domain subcarrier offset of the SSB relative to the Common Resource Block (CRB), denoted as k. SSB This field can be expanded to 5 bits using one coded bit in the PBCH transport block. The SSB subcarrier offset may indicate that the cell does not provide SIB1. In this case, the SIB1 Physical downlink control channel (PDCCH) configuration field indicates whether the UE can find the frequency location of the SSB carrying SIB1 scheduling information, or whether the UE cannot find the frequency range of the SSB carrying SIB1 scheduling information.

[0060] Demodulation Reference Signal (DMRS) Type A Position: Indicates the position of the first downlink (DL) and uplink (UL) DMRS.

[0061] PDCCH SIB1 configuration (pdcch-ConfigSIB1): This determines a common control resource set (CORESET), a common search space, and necessary PDCCH parameters. If the SSB subcarrier offset might indicate that the cell does not provide SIB1, then the PDCCH SIB1 configuration field indicates whether the UE can find the frequency location of the SSB carrying SIB1 scheduling information, or whether the UE cannot find the frequency range of the SSB carrying SIB1 scheduling information.

[0062] CellBarred: Indicates whether the cell prohibits UE from camping;

[0063] IntraFreqReselection: Indicates whether intrafrequency cell reselection is allowed; controls intrafrequency reselection when high-priority cells are prohibited from access.

[0064] The embodiments of this disclosure provide a method, apparatus, terminal, and network-side device for determining the location of system information resources, in order to solve the problem of wasted power consumption during the terminal's detection of SIB1 PDSCH.

[0065] The method and apparatus are based on the same concept of the application. Since the methods and apparatus solve problems in similar ways, the implementation of the apparatus and methods can refer to each other, and the repeated parts will not be described again.

[0066] As shown in Figure 1, an embodiment of this disclosure provides a method for determining the location of system information resources, applied to a terminal, specifically including the following steps:

[0067] Step 101: The terminal determines the resource location of the physical layer downlink shared channel (PDSCH) of the bearing system information block (SIB) based on the relevant information of the first target object.

[0068] The relevant information of the first target object includes at least one of the following: scheduling information indicated by the first target object; resource location of the first target object;

[0069] The first target object includes at least one of the following: a first broadcast channel; a synchronization block.

[0070] In this embodiment, the first target object can be sent by a network-side device. The terminal receives the first target object and determines the resource location of the PDSCH carrying the SIB based on the relevant information of the first target object. The first target object can be a first broadcast channel, such as a PBCH or other broadcast channels with the same or similar functions. The first broadcast channel can explicitly or implicitly indicate scheduling information, such as directly indicating the content of the scheduling information or indicating the index corresponding to the scheduling information. The scheduling information can be the scheduling information of the PDSCH carrying the SIB. The terminal can directly determine the resource location of the PDSCH carrying the SIB based on the scheduling information indicated by the first broadcast channel, and thus can receive the PDSCH carrying the SIB at the determined resource location.

[0071] The terminal can also determine the resource location of the PDSCH carrying the SIB based on the resource location of the first broadcast channel. The resource location of the first broadcast channel and the resource location of the PDSCH carrying the SIB are related, such as having a certain offset between them or a fixed mapping relationship.

[0072] Taking the first broadcast channel as PBCH as an example, the terminal can directly determine the resource location of the PDSCH carrying the SIB based on the scheduling information indicated by the PBCH, or it can determine the resource location of the PDSCH carrying the SIB based on the resource location of the PBCH.

[0073] The first target object can also be a synchronization block, which is a functional block used for synchronization, such as a synchronization signal block (SSB), or other synchronization blocks with the same or similar functions as the SSB. The synchronization block can explicitly or implicitly indicate scheduling information, such as directly indicating the content of the scheduling information or indicating the index corresponding to the scheduling information. The scheduling information indicated by the synchronization block can be scheduling information indicated by synchronization signals (e.g., PSS, SSS) within the synchronization block. For example, the synchronization signals in the synchronization block carry the scheduling information through a sequence, or the resources of the synchronization signals in the synchronization block correspond to the resources of the PDSCH carrying the SIB. Alternatively, the scheduling information indicated by the synchronization block can also be scheduling information indicated by the PBCH within the synchronization block, which can be the scheduling information of the PDSCH carrying the SIB. The terminal can determine the resource location of the PDSCH carrying the SIB based on the scheduling information indicated by the synchronization block, and thus can receive the PDSCH carrying the SIB at the determined resource location.

[0074] The terminal can also determine the resource location of the PDSCH carrying the SIB based on the resource location of the synchronization block. The resource location of the synchronization block and the resource location of the PDSCH carrying the SIB are related, for example, they have a certain offset or a fixed mapping relationship. The resource location of the synchronization block can be the resource location of the synchronization signal (e.g., PSS, SSS) in the synchronization block, or it can be the resource location of the PBCH in the synchronization block.

[0075] It should be noted that the first broadcast channel may be included in the synchronization block or it may be an independent broadcast channel. For example, if the synchronization block includes the first broadcast channel, the terminal can determine the resource location of the PDSCH carrying the SIB based on the scheduling information indicated by the first broadcast channel or the scheduling information indicated by the synchronization block. The scheduling information indicated by the first broadcast channel and the scheduling information indicated by the synchronization block may be the same, or the scheduling information indicated by the first broadcast channel may be considered as the scheduling information indicated by the synchronization block. The terminal can also determine the resource location of the PDSCH carrying the SIB based on the resource location of the first broadcast channel or the resource location of the synchronization block. The resource location of the first broadcast channel may also be considered as the resource location of the synchronization block.

[0076] The terminal can also determine the resource location of the PDSCH carrying the SIB based on the scheduling information indicated by the first target object and the resource location of the first target object. For example, the scheduling information indicates the offset between the resource location of the first target object and the resource location of the PDSCH carrying the SIB. The terminal can determine the resource location of the PDSCH carrying the SIB based on the offset and the resource location of the first target object.

[0077] In this embodiment of the disclosure, the SIB can be System Information Block 1 (SIB1) or other SIBs.

[0078] In embodiments of this disclosure, the terminal determines the resource location of the PDSCH carrying the SIB based on the scheduling information indicated by the first target object and / or the resource location of the first target object. The first target object may be a first broadcast channel and / or a synchronization block. This scheme simplifies the process of the terminal determining the resource location of the PDSCH carrying the SIB, and also simplifies the process of the network-side device sending the PDSCH carrying the SIB, which is beneficial for the terminal and the network-side device to save power consumption.

[0079] In some embodiments, the scheduling information includes at least one of the following:

[0080] (1) First offset information: The first offset information is the offset between the resource location of the first target object and the resource location of the PDSCH carrying the SIB. For example, the offset between the resource location of the first broadcast channel and the resource location of the PDSCH carrying the SIB, or the offset between the resource location of the synchronization block and the resource location of the PDSCH carrying the SIB. Based on the first offset information and the resource location of the first target object, the terminal can determine the resource location of the PDSCH carrying the SIB. For example, as shown in Figure 2, assuming the first target object is PBCH, the terminal can determine the resource location of the PDSCH of SIB1 based on the resource location of PBCH and the first offset. At this time, it is no longer necessary to indicate the scheduling information of the PDSCH carrying the SIB through DCI, which is beneficial to network energy saving.

[0081] (2) Periodic transmission configuration information of the PDSCH carrying the SIB; the first target object may also indicate the periodic transmission configuration information of the PDSCH carrying the SIB. In some embodiments, the periodic transmission configuration information includes at least one of the following:

[0082] The value of the transmission period of the PDSCH carrying the SIB;

[0083] The starting position of the PDSCH carrying the SIB within the transmission cycle;

[0084] The end position of the PDSCH carrying the SIB within the transmission cycle;

[0085] The transmission duration of the PDSCH carrying the SIB within the transmission cycle;

[0086] The number of transmissions of the PDSCH carrying the SIB within a transmission cycle;

[0087] The first index is an index corresponding to the periodic transmission configuration information. The periodic transmission configuration information corresponding to the first index may include one or more of the above-mentioned configuration information contents. Based on the first index, at least one of the above-mentioned periodic transmission configuration information can be determined. For example, if the first target object indicates that the first index is 2, the periodic transmission configuration information corresponding to index 2 includes: the value of the transmission period, the starting position of the PDSCH carrying the SIB within the transmission period, the transmission duration of the PDSCH carrying the SIB within the transmission period, and the number of transmissions of the PDSCH carrying the SIB within the transmission period.

[0088] The terminal can determine the resource location of the PDSCH carrying the SIB based on this periodic transmission configuration information.

[0089] (3) The temporal resource location of the PDSCH carrying the SIB; the first target object can also indicate the temporal resource location of the PDSCH carrying the SIB, so that the terminal can directly determine the temporal resource location of the PDSCH carrying the SIB according to the indication of the first target object. The temporal resource location can be the absolute time information of the PDSCH carrying the SIB, such as at least one of the following: the start time unit of the PDSCH carrying the SIB, the time unit length of the PDSCH carrying the SIB, etc. The start time unit is, for example, the starting subframe and / or the starting time slot and / or the starting symbol of the PDSCH carrying the SIB, etc. The time unit length can be the number of subframes and / or the number of time slots and / or the number of symbols occupied by the PDSCH carrying the SIB, etc.

[0090] (4) Frequency domain resource location of the PDSCH carrying the SIB. The first target object can also indicate the frequency domain resource location of the PDSCH carrying the SIB, so that the terminal can directly determine the frequency domain resource location of the PDSCH carrying the SIB based on the indication of the first target object. The frequency domain resource location can be the absolute frequency domain information of the PDSCH carrying the SIB, such as at least one of the following: the number of subcarriers occupied by the PDSCH carrying the SIB, the starting position of the occupied subcarriers, the number of occupied resource blocks (RBs), the starting position of the occupied resource blocks, etc.

[0091] It should be noted that the scheduling information may also include multiple items of the above information. For example, the first target object may indicate the time-domain resource location and frequency-domain resource location of the PDSCH carrying the SIB, or the first target object may indicate the periodic transmission configuration information and time-domain resource location of the PDSCH carrying the SIB, or the first target object may indicate the periodic transmission configuration information and frequency-domain resource location of the PDSCH carrying the SIB, or the first target object may indicate the first offset information and the periodic transmission configuration information. These are not listed one by one here.

[0092] In some embodiments, the scheduling information may include, in addition to one or more of the information described above, at least one of the following: mapping information between Virtual Resource Blocks (VRBs) and PRBs, modulation indication information, and redundancy version information. One or more of the above scheduling information can be indicated by different fields in the MIB.

[0093] In some embodiments, the first target object indicates the first offset information in a manner that includes at least one of the following:

[0094] The first target object indicates the value of the first offset information;

[0095] The first target object carries a third index, which is the index corresponding to the first offset information.

[0096] In this embodiment, the first target object can explicitly or implicitly indicate the first offset information, such as directly indicating the value of the first offset information or indicating the index corresponding to the first offset information. For example, the network pre-configures or the protocol predefines multiple indices corresponding to offset information. The network-side device indicates the target index in the first target object. The terminal can determine the corresponding first offset information based on the target index. Based on the first offset information and the resource location of the first target object, the resource location of the PDSCH carrying the SIB can be determined.

[0097] In some embodiments, the first offset information includes: frequency domain offset information and / or time domain offset information;

[0098] The frequency domain offset information includes at least one of the following:

[0099] The number of frequency domain units between the first target object and the common resource block (CRB);

[0100] The number of frequency domain units between the first target object and the PDSCH carrying the SIB;

[0101] The time-domain offset information includes the number of time units between the first target object and the PDSCH carrying the SIB.

[0102] In this embodiment, the first offset information can be time-domain offset information and / or frequency-domain offset information. The first target object indicating frequency-domain offset information can be the number of frequency-domain cells indicating the interval between the first target object and the CRB, or the number of frequency-domain cells indicating the interval between the first target object and the PDSCH carrying the SIB. The frequency-domain cells include at least one of the following: subcarriers and RBs. For example, if the first target object is a PBCH, the PBCH can indicate the frequency-domain offset between the SSB / PBCH and the SIB1 PDSCH. This frequency-domain offset can include at least one of the following: the number of subcarriers between the SSB / PBCH and the CRB / SIB1 PDSCH; and the number of consecutive RBs between the SSB / PBCH and the SIB1 PDSCH. The frequency-domain offset information can be directly displayed in the first target object or determined by the index indicated by the first target object.

[0103] The first target object indicates the time-domain offset information, which may indicate the number of time units between the first target object and the PDSCH carrying the SIB. The time unit includes at least one of the following: time slot, symbol, frame, and subframe. For example, the first target object is a PBCH, which indicates the time-domain offset between the SSB / PBCH and the SIB1 PDSCH. This time-domain offset may be at least one of the following: the number of time slots between the SSB / PBCH and the SIB1 PDSCH, the number of symbols between the SSB / PBCH and the SIB1 PDSCH, the number of subframes between the SSB / PBCH and the SIB1 PDSCH, or the number of system frames between the SSB / PBCH and the SIB1 PDSCH. This time-domain offset can be displayed in the first target object or determined by an index indicated by the first target object.

[0104] For example, the offset information between the resource location of the first target object and the resource location of the PDSCH carrying the SIB can be a fixed value agreed upon by the network configuration or protocol. Different offset information corresponds to different indices, and the first target corresponds to the target index. The terminal can determine the first offset information based on the correspondence between the offset information and the index.

[0105] In some embodiments, when the first target object is the first broadcast channel, the master information block (MIB) carried by the first broadcast channel contains at least a portion of the scheduling information; and / or, the physical layer information of the first broadcast channel contains at least a portion of the scheduling information.

[0106] In this embodiment, the scheduling information of the PDSCH carrying the SIB can be included in the MIB, or in the physical layer information, or some scheduling information can be included in the MIB and the rest in the physical layer information. For example, if the first target object is the PBCH, the scheduling information of the SIB PDSCH can be included in the PBCH's MIB, or in the PBCH's physical layer information, or some scheduling information can be included in both the MIB and the PBCH's physical layer information.

[0107] In some embodiments, the first field in the MIB contains at least a portion of the scheduling information; the first field includes at least one of the following: a system frame number field; a physical downlink control channel (PDCCH) configuration information field; and a subcarrier common interval field.

[0108] In this embodiment, when the MIB contains scheduling information of the PDSCH carrying the SIB, one or more of the following fields may contain the scheduling information: system frame number field (systemFrameNumber), configuration information field (pdcch-ConfigSIB1) of the PDCCH, and subcarrier common interval field (subCarrierSpacingCommon).

[0109] In this scenario, the first field in the MIB has different interpretations depending on whether the network is in power-saving or non-power-saving mode. For example, in non-power-saving mode, the pdcch-ConfigSIB1 field in the MIB indicates the common control resource set (CORESET) and common search space information of the SIB1 PDCCH, while the system frame number field indicates partial information about the system frame number of the cell. When the network-side equipment is in power-saving mode, the pdcch-ConfigSIB1 field and system frame number field in the MIB can be reinterpreted to indicate the scheduling information of the PDSCH carrying SIB1.

[0110] In some embodiments, the terminal can also determine the resource location of the PDSCH carrying the SIB based on the resource location of the first target object. In some embodiments, the resource location of the first target object and the resource location of the PDSCH carrying the SIB have a mapping relationship. The mapping relationship can be agreed upon by a protocol, predefined, or configured by the network side. For example: if the resource location of the first target object is A, the resource location of the PDSCH carrying the SIB is N time slots after A; if the resource location of the first target object is B, the resource location of the PDSCH carrying the SIB is N time slots after B. The terminal can directly determine the resource location of the PDSCH carrying the SIB based on the resource location of the first target object and the mapping relationship.

[0111] In some embodiments, the first target object and the PDSCH carrying the SIB have a first resource configuration mode, and the resource location of the PDSCH carrying the SIB is related to the first resource configuration mode.

[0112] In some embodiments, the first resource configuration mode includes one of the following:

[0113] The first target object overlaps with the time domain resources of the PDSCH carrying the SIB, but the frequency domain resources do not overlap.

[0114] The first target object overlaps with the frequency domain resources of the PDSCH carrying the SIB, but their time domain resources do not overlap.

[0115] The first target object does not overlap with the time domain resources and frequency domain resources of the PDSCH carrying the SIB.

[0116] In this embodiment, the resource location of the first target object and the resource location of the PDSCH carrying the SIB satisfy the first resource configuration mode. For example, frequency division, time division, or a combination of frequency and time division modes. Specifically, in frequency division mode, the time-domain resources of the first target object and the PDSCH carrying the SIB overlap, but their frequency-domain resources do not overlap. For example, the scheduling information may include the frequency-domain offset between the first target object and the PDSCH carrying the SIB, allowing the terminal to determine the frequency-domain location of the PDSCH carrying the SIB based on the frequency-domain location of the first target object and the frequency-domain offset.

[0117] In time-division mode, the frequency domain resources of the first target object and the PDSCH carrying the SIB overlap, but the time domain resources do not overlap. For example, the scheduling information may include the time domain offset between the first target object and the PDSCH carrying the SIB. The terminal can determine the time domain position of the PDSCH carrying the SIB based on the time domain position of the first target object and the time domain offset.

[0118] In frequency division and time division mode, the time domain resources of the first target object and the PDSCH carrying the SIB do not overlap and the frequency domain resources do not overlap. For example, the scheduling information may include the time domain offset and frequency domain offset between the first target object and the PDSCH carrying the SIB. The terminal can determine the time domain position of the PDSCH carrying the SIB based on the time domain position of the first target object and the time domain offset, and determine the frequency domain position of the PDSCH carrying the SIB based on the frequency domain position of the first target object and the frequency domain offset.

[0119] In some embodiments, the first target object carries a second index, which is an index of a first resource configuration pattern between the first target object and the PDSCH carrying the SIB.

[0120] In this embodiment, the first target object carries a second index. This can be understood as the first target object containing or indicating the value of the second index, or the first target object implicitly indicating the second index through a predefined or preconfigured method. For example, a target field indicating 00 in the first target object means the second index is 0, a target field indicating 01 means the second index is 1, a target field indicating 11 means the second index is 2, and so on. For example, if the first target object is a PBCH, the time-domain / frequency-domain offset between the PBCH and the SIB1PDSCH can be a fixed value agreed upon by the protocol, that is, the source configuration pattern between the two is fixed. In the case of multiple first resource configuration patterns, the index indicating the pattern in the PBCH can also be understood as the PBCH indicating that the scheduling information of the SIB PDSCH is specifically an index of a resource configuration pattern pattern.

[0121] In some embodiments, the first target object carries first indication information, which indicates that the first target object is associated with a PDSCH carrying an SIB, and / or indicates that the first target object does not have an associated PDSCH carrying an SIB.

[0122] In this embodiment, the first target object carries first indication information, such as fields within the first target object indicating the first indication information or related information such as an index of the first indication information, or the first target object having an association with the first indication information. This first indication information is used to indicate whether the current first target object is associated with a PDSCH carrying an SIB. The first target object may be associated with one or more PDSCHs carrying SIBs, in which case the relevant information of the first target object can be used to determine the resource location of the associated PDSCH carrying the SIB. The first target object may also not have an associated PDSCH carrying an SIB; in this case, the relevant information of the first target object cannot be used to determine the resource location of the PDSCH carrying the SIB. This can also be understood as not every resource location of a first target object can be combined with offset information to determine the resource location of a PDSCH carrying an SIB. There is a many-to-one relationship between the first target object and the PDSCH carrying the SIB. It can be understood that the first target object carrying the first indication information can also indicate that X first target objects are associated with one PDSCH carrying an SIB.

[0123] It should be noted that the first indication information indicates whether the current first target object has an associated PDSCH of a bearer SIB. This can also be understood as the first indication information carried by the first target object indicating whether it has an associated PDSCH of a bearer SIB. For example, when a terminal receives a PBCH sent by a network-side device, based on the first indication information carried by the PBCH, it can determine whether the PBCH is associated with a PDSCH of a certain bearer SIB, or it can be understood as determining whether the relevant information of the PBCH can be used to determine the resource location of the PDSCH of the bearer SIB.

[0124] In some embodiments, when the network-side device is in an energy-saving state and / or when the terminal sends an uplink wake-up signal (WUS) to the network-side device, the relevant information of the first target object is used to determine the resource location of the PDSCH carrying the SIB.

[0125] In this embodiment, when the network-side device is in an energy-saving state, the terminal can determine the resource location of the PDSCH carrying the SIB based on the relevant information of the first target object sent by the network-side device. For example, if the network-side device is in an energy-saving state, the first target object sent carries the scheduling information of the PDSCH carrying the SIB, or it is assumed that the resource location of the first target object sent by the network-side device at this time can be used to determine the resource location of the PDSCH carrying the SIB.

[0126] When the network-side equipment is in power-saving or non-power-saving mode, the fields in the first target object can be interpreted differently. For example, in non-power-saving mode, the pdcch-ConfigSIB1 field in the MIB indicates the CORESET and common search space information of the SIB1 PDCCH, and the system frame number field in the MIB indicates partial information about the system frame number of the cell. When the network-side equipment is in power-saving mode, the pdcch-ConfigSIB1 field, system frame number field, etc., in the MIB can be used to indicate the scheduling information of the PDSCH carrying the SIB.

[0127] The terminal can also send an uplink WUS to the network-side device, which triggers the network-side device to send a first target object. At this time, the first target object carries the scheduling information of the PDSCH carrying the SIB, or by default, the resource location of the first target object sent by the network-side device can be used to determine the resource location of the PDSCH carrying the SIB.

[0128] In some embodiments, the method further includes:

[0129] Send an uplink wake-up signal (WUS) to the network-side device. The uplink WUS carries first information, which is used to request at least one of the following:

[0130] The network-side device transmits a first broadcast channel and a PDSCH carrying an SIB;

[0131] The network-side device sends a synchronization block and a PDSCH carrying an SIB;

[0132] The network-side device sends a first broadcast channel;

[0133] The network-side device sends a synchronization block;

[0134] The network-side device sends a PDSCH carrying the SIB.

[0135] In this embodiment, the terminal sends an uplink WUS to the network-side device, which can be used to request the network-side device to send a first target object and / or the PDSCH carrying the SIB. It should be noted that the first target object triggered by the terminal sending the uplink WUS request may be different from the first target object of the PDSCH carrying the SIB determined by the terminal. For example: the uplink WUS is used to trigger the network-side device to send a first broadcast channel and the PDSCH carrying the SIB; the terminal can determine the resource location of the PDSCH carrying the SIB based on the relevant information of the synchronization block. Another example: the uplink WUS is used to trigger the network-side device to send a synchronization block; the terminal can determine the resource location of the PDSCH carrying the SIB based on the first broadcast channel. Yet another example: the first broadcast channel may be included within the synchronization block; the terminal sends an uplink WUS to trigger the network-side device to send the first broadcast channel; the terminal can determine the resource location of the PDSCH carrying the SIB based on the relevant information of the first broadcast channel, or it can determine the resource location of the PDSCH carrying the SIB based on the relevant information of the synchronization block.

[0136] In some embodiments, the first information is carried by sequence information of the uplink WUS, and / or, the first information is carried by resource information of the uplink WUS. Specifically, different sequence information can be used to carry first information for requesting different content, and / or different resource information can be used to carry first information for requesting different content.

[0137] The following example illustrates how the terminal determines the resource location of the PDSCH carrying the SIB based on the relevant information of the first target object.

[0138] Example 1: The terminal determines the resource location of the PDSCH carrying the SIB based on the scheduling information indicated by the first target object. Taking the first target object as PBCH, which is contained within an SSB, and the SIB as SIB1 as an example.

[0139] The PBCH may include scheduling information for the PDSCH carrying SIB1. The payload bits included in the PBCH include payload bits generated by the higher layers and payload bits generated by the physical layer. This scheduling information may be included in the payload bits generated by the higher layers, such as the MIB, without limitation. For example, the scheduling information may be included in the payload bits generated by the physical layer; or, some of the scheduling information for the PDSCH carrying SIB1 may be included in the MIB, and the rest may be included in the payload bits of the physical layer; or, the entire content of the scheduling information for the PDSCH carrying SIB1 may be included in the MIB.

[0140] In non-energy-saving mode, the network-side device transmits the SSB signal periodically and the PBCH channel periodically. When the network-side device wants to conserve network power and is in energy-saving mode, the PBCH is transmitted on demand, for example, only when the UE sends a UL WUS request for PBCH. The scheme in this embodiment where the PBCH indicates the scheduling information of the PDSCH carrying SIB1 can be a PBCH transmitted when the network-side device is in energy-saving mode. Only when the network-side device wants to conserve network power will it indicate the scheduling information of the PDSCH carrying SIB1 in the transmitted PBCH. In non-energy-saving mode, the PBCH still indicates pdcch-ConfigSIB1, and the UE then detects the SIB1 PDCCH through pdcch-ConfigSIB1. The SIB1 PDCCH includes the scheduling information of the PDSCH carrying SIB1.

[0141] The scheduling information in the PBCH indicating the PDSCH carrying SIB1 may include the following two methods:

[0142] Method 1: Some fields in the MIB are used to indicate the scheduling information of the PDSCH carrying SIB1. These fields can be newly added fields or pre-set fixed fields. The scheduling information may include information related to the resource location of SIB1, such as frequency domain resource allocation information and time domain resource allocation information of the PDSCH. In addition, the scheduling information of the PDSCH carrying SIB1 may also include VRB-PRB mapping information, modulation indication information, and redundancy version information. Different fields in the MIB are used to indicate one or more of the above scheduling information.

[0143] Method 2: Some fields in the MIB have different interpretations in energy-saving and non-energy-saving states. For example, in non-energy-saving state, the pdcch-ConfigSIB1 field in the MIB indicates the CORESET and common search space information of the PDSCH carrying SIB1; the system frame number field in the MIB indicates partial information about the cell's system frame number. In energy-saving state, the pdcch-ConfigSIB1 field and the system frame number field in the MIB can be reinterpreted to indicate the scheduling information of the PDSCH carrying SIB1. If the system frame number field is no longer provided in the current cell's MIB, it can be provided by other cells, such as neighboring cells.

[0144] When the cell is in a non-energy-saving state, the PBCH indicates the CORESET and common search space information of the PDSCH carrying SIB1; when the cell is in an energy-saving state, the PBCH indicates the scheduling information of the PDSCH carrying SIB1. Since the number of indication bits required for the common control resource set (CORESET) and scheduling information of the PDSCH carrying SIB1 differs, the scheduling information of the PDSCH carrying SIB1 requires more bits. Therefore, the frequency domain resources and / or time domain resources occupied by the PBCH differ between the cell's non-energy-saving and energy-saving states. The frequency domain resources occupied by the PBCH in the energy-saving state are greater than those in the non-energy-saving state; and / or, the time domain resources occupied by the PBCH in the energy-saving state are greater than those in the non-energy-saving state.

[0145] The PBCH includes scheduling information for the PDSCH carrying SIB1, which can be periodic transmission configuration information for the PDSCH carrying SIB1. This includes information such as the transmission period of the PDSCH carrying SIB1, the start and end positions of the PDSCH within the transmission period, the transmission duration, and the number of transmissions. The PBCH can explicitly indicate the values ​​of some parameters for the periodic transmission of the PDSCH carrying SIB1. Based on these specific values ​​of the periodic transmission configuration information, the terminal can determine the resource location of the PDSCH carrying SIB1.

[0146] Alternatively, the PBCH can also include an index corresponding to the periodic transmission configuration information. Different periodic transmission configuration information can correspond to different indices. For example, the correspondence between the index and the values ​​of some parameters of the periodic transmission configuration information can be agreed upon by the protocol.

[0147] In this embodiment, the terminal determines the resource location of the PDSCH carrying the SIB based on the scheduling information indicated by the PBCH, without having to determine it through the control channel, thus saving the execution time for receiving the SIB. Furthermore, the network-side device does not need to send the scheduling information of the SIB through the control channel, thus saving network power consumption.

[0148] Example 2: When the terminal determines the resource location of the PDSCH carrying the SIB based on the scheduling information indicated by the first target object, a resource allocation relationship exists between the first target object and the PDSCH carrying the SIB. Taking the first target object as SSB / PBCH and the SIB as SIB1 as an example.

[0149] There are three resource allocation modes for the SSB / PBCH and the PDSCH carrying the SIB: time-division, frequency-division, and time-division and frequency-division. As shown in Figure 3, the SSB / PBCH and the PDSCH carrying the SIB are in a time-division multiplexing relationship. Schematic diagrams for frequency-division and time-division and frequency-division are not shown here.

[0150] For example, the PBCH indicates the frequency domain resource information of the PDSCH carrying the SIB. Specifically, this frequency domain resource information can be the frequency domain offset between the SSB / PBCH and the PDSCH carrying the SIB. This frequency domain offset can include at least one of the following:

[0151] (1) The number of subcarriers spaced between SSB / PBCH and PDSCH carrying SIB;

[0152] The number of subcarriers can be the subcarrier offset of the SSB / PBCH relative to the CRB in the frequency domain, such as kSSB in Figure 3. The subcarrier offset is, for example, the subcarrier offset between the subcarrier 0 of the RB with the lowest position in the frequency domain of the SSB / PBCH and the subcarrier 0 of the CRB that overlaps with the subcarrier 0 of that RB.

[0153] For the frequency division or time division and frequency division resource allocation mode between SSB / PBCH and PDSCH carrying SIB, the number of subcarriers spaced between SSB / PBCH and PDSCH carrying SIB can be determined based on kSSB.

[0154] (2) The number of consecutive RBs between the SSB / PBCH and the PDSCH carrying the SIB, as shown in Figure 3, corresponding to the number of RBs for the offset. The number of RBs in this interval is the offset from the first RB with the lowest position in the frequency domain of the PDSCH carrying the SIB to the CRB that overlaps with the subcarrier 0 of the RB with the lowest position in the frequency domain of the SSB / PBCH.

[0155] Here, the subcarrier spacing corresponding to the number of RBs and / or the number of subcarriers in the frequency domain offset between the SSB / PBCH and the PDSCH carrying the SIB can be the same as or equal to the subcarrier spacing of the PDSCH carrying the SIB.

[0156] The frequency domain resource information of the PDSCH carrying the SIB indicated in the PBCH may also include: the number of RBs corresponding to the PDSCH carrying the SIB, and the subcarrier spacing corresponding to the number of RBs is the subcarrier spacing of the PDSCH carrying the SIB. The subcarrier spacing may be configured in the MIB or agreed upon by the protocol.

[0157] For example, the PBCH indicates the time-domain resource information of the PDSCH carrying the SIB. Specifically, this time-domain resource information can be the time-domain offset between the SSB / PBCH and the PDSCH carrying the SIB. This time-domain offset can include at least one of the following:

[0158] (1) The number of subframes (or frames) and / or slots and / or symbols offset between SSB / PBCH and PDSCH carrying SIB, as shown in K0 in Figure 3;

[0159] a: The time-domain offset between the SSB / PBCH and the PDSCH carrying the SIB can be: the time-domain offset between the first symbol of the SSB / PBCH and the first symbol of the PDSCH carrying the SIB, such as: the number of time slots offset between the first symbol of the SSB / PBCH and the first symbol of the PDSCH carrying the SIB;

[0160] b: The time-domain offset between the SSB / PBCH and the PDSCH carrying the SIB can be: the time-domain offset between the last symbol of the SSB / PBCH and the first symbol of the PDSCH carrying the SIB, such as: the number of time slots offset between the last symbol of the SSB / PBCH and the first symbol of the PDSCH carrying the SIB;

[0161] c: The time-domain offset between the SSB / PBCH and the PDSCH carrying the SIB can be: the time-domain offset between the first symbol of the SSB / PBCH and the last symbol of the PDSCH carrying the SIB; or, the time-domain offset between the SSB / PBCH and the PDSCH carrying the SIB can be: the time-domain offset between the last symbol of the SSB / PBCH and the last symbol of the PDSCH carrying the SIB.

[0162] (2) The time-domain offset between SSB / PBCH and PDSCH carrying SIB can include offsets of more than one time type, such as: time-domain offsets include slot offsets and symbol offsets, subframe offsets and radio frame offsets, etc.

[0163] The temporal resource information of the PDSCH carrying the SIB, as indicated by the PBCH, may also include: absolute time information indicating the location of the PDSCH carrying the SIB, such as: the position of the start symbol (and / or end symbol) of the PDSCH carrying the SIB in the time slot, the duration of the PDSCH carrying the SIB, etc., which may be the number of subframes (or frames) and / or time slots and / or symbols occupied by the PDSCH carrying the SIB.

[0164] In the above scheme, the PBCH may further include first indication information, which indicates whether the current SSB / PBCH will be associated with a PDSCH carrying an SIB, or indicates that X SSB / PBCHs are associated with a PDSCH carrying an SIB. In this embodiment, not the resource location of each SSB / PBCH can be combined with offset information to determine the resource location of a PDSCH carrying an SIB. There is a many-to-one relationship between SSB / PBCHs and PDSCHs carrying SIBs, and one SSB / PBCH among multiple SSB / PBCHs and the PDSCH carrying an SIB have a time-division, frequency-division, or time-division and frequency-division resource allocation relationship.

[0165] Example 3: When the terminal determines the resource location of the PDSCH carrying the SIB based on the scheduling information indicated by the first target object, the scheduling information indicated by the first target object is the index corresponding to the time-domain (and / or frequency-domain) resource of the PDSCH carrying the SIB. Taking the first target object as SSB / PBCH and the SIB as SIB1 as an example.

[0166] In Example 2, the PBCH can explicitly indicate the specific values ​​of the frequency domain resource information and / or time domain resource information of the PDSCH carrying the SIB. The UE can directly obtain the frequency domain resources and / or time domain resources corresponding to the PDSCH carrying the SIB based on the content indicated in the PBCH.

[0167] In addition, the PBCH can also indicate the index corresponding to the frequency domain resource information of the PDSCH carrying the SIB. For example, this index corresponds to at least one table in the protocol, which includes various parameters of the frequency domain resources of the PDSCH carrying the SIB, such as the number of subcarriers between the SSB / PBCH and the PDSCH carrying the SIB, and the number of consecutive RBs between the SSB / PBCH and the PDSCH carrying the SIB. The UE can determine the frequency domain resources corresponding to the PDSCH carrying the SIB based on the index and table corresponding to the frequency domain resource information of the PDSCH carrying the SIB.

[0168] Similarly, the PBCH can also indicate an index corresponding to the time-domain resource information of the PDSCH carrying the SIB. For example, this index corresponds to at least one table in the protocol, which includes various parameters of the time-domain resources of the PDSCH carrying the SIB, such as the time slot (and / or one or more of the subframe, frame, symbol, etc.) between the SSB / PBCH and the PDSCH carrying the SIB. The UE can determine the time-domain resources corresponding to the PDSCH carrying the SIB based on the index and table corresponding to the time-domain resource information of the PDSCH carrying the SIB.

[0169] For example, there are several predefined fixed time-domain and / or frequency-domain resource allocation patterns between the SSB / PBCH and the PDSCH carrying the SIB. By indicating the index corresponding to these predefined time-domain and / or frequency-domain resource allocation patterns in the PBCH, the terminal can determine the time-domain and / or frequency-domain resources of the PDSCH carrying the SIB.

[0170] Example 4: When the network-side equipment is in network power-saving mode, the UE sends a UL WUS request to send the first target object. The first target object is the PBCH, for example.

[0171] When network-side equipment wishes to conserve network power and is in energy-saving mode, the PBCH is sent on demand. The network-side equipment only sends the PBCH when the UE sends a UL WUS request. The PBCH only provides the UE with some key cell access information; the UE still needs to obtain other cell access information based on the PDSCH carrying SIB1.

[0172] When the PBCH includes the PDSCH common control resource set CORESET carrying SIB1 and common search space information, the UE can perform the following operations:

[0173] The UE detects the PSS / SSS for downlink synchronization; the UE sends UL WUS1 to request the PBCH, which includes the Type#0CSS configuration; the UE sends UL WUS2 to request the PDSCH carrying SIB1; the UE blindly monitors the PDCCH carrying SIB1 according to the Type#0CSS; the UE receives the SIB1 PDSCH according to the scheduling of the SIB1 PDCCH.

[0174] According to the scheme of this disclosure embodiment, the PBCH can directly indicate the scheduling information of the PDSCH carrying SIB1. The UE behavior is as follows: the UE detects PSS / SSS and performs downlink synchronization; the UE sends UL WUS1 to request the PBCH, which includes the scheduling information of the PDSCH carrying SIB1; the UE sends UL WUS2 to request the PDSCH carrying SIB1; the UE receives the PDSCH carrying SIB1 according to the scheduling information of the PDSCH carrying SIB1 included in the PBCH.

[0175] In some embodiments, in order to reduce UE power consumption and enable the UE to receive SIB1 faster, the UE may perform the following actions:

[0176] The UE detects the PSS / SSS and performs downlink synchronization; the UE sends a UL WUS1 request PBCH and a PDSCH carrying SIB1, the PBCH including the scheduling information of the PDSCH carrying SIB1; the UE receives the PDSCH carrying SIB1 according to the scheduling information of the PDSCH carrying SIB1 included in the PBCH.

[0177] In the three scenarios described above, the UL WUS sent by the UE may request "PBCH and PDSCH carrying SIB1", or request "PBCH", or request "PDSCH carrying SIB1". Therefore, the UL WUS can carry first information, which is used to request the network-side device to send "PBCH and PDSCH carrying SIB1", or send "PBCH" or send "PDSCH carrying SIB1".

[0178] UL WUS can carry different first information through different sequences. By sending UL WUS with different sequences, the UE enables the network-side device to determine the message type that the UE wants to request. The message type can be "PBCH and PDSCH carrying SIB1" or "PBCH" or "PDSCH carrying SIB1".

[0179] UL WUS can carry different first information on different resources. By sending UL WUS on different resources, the UE enables the network-side device to determine the message type that the UE wants to request. The message type can be "PBCH and PDSCH carrying SIB1" or "PBCH" or "PDSCH carrying SIB1".

[0180] UL WUS can also carry different content of primary information through different sequences and different resources, which will not be elaborated here.

[0181] In this embodiment, the network-side device sends time-domain and / or frequency-domain resource-related information for detecting the PDSCH carrying SIB1 in the MIB of the PBCH. By indicating the scheduling information of the PDSCH carrying SIB1 in the PBCH, the UE can determine the resource location of SIB1. The process of the UE receiving the PDSCH carrying SIB1 is as follows: receive SSB / PBCH; receive the PDSCH carrying SIB1. This process helps the network-side device save power.

[0182] In embodiments of this disclosure, the terminal determines the resource location of the PDSCH carrying the SIB based on the scheduling information indicated by the first target object and / or the resource location of the first target object. The first target object may be a first broadcast channel and / or a synchronization block. This scheme simplifies the process of the terminal determining the resource location of the PDSCH carrying the SIB, and also simplifies the process of the network-side device sending the PDSCH carrying the SIB, which is beneficial for the network-side device to save power consumption.

[0183] As shown in Figure 4, this embodiment of the present disclosure also provides a method for determining the location of system information resources, applied to a network-side device, including:

[0184] Step 401: The network-side device sends a first target object to the terminal. The relevant information of the first target object is used to determine the resource location of the PDSCH carrying the SIB.

[0185] The relevant information of the first target object includes at least one of the following: scheduling information indicated by the first target object; resource location of the first target object;

[0186] The first target object includes at least one of the following: a first broadcast channel; a synchronization block.

[0187] In this embodiment, the network-side device sends the first target object, the terminal receives the first target object, and determines the resource location of the PDSCH carrying the SIB based on the relevant information of the first target object. The first target object can be a first broadcast channel, such as a PBCH or other broadcast channels with the same or similar functions as a PBCH. The first broadcast channel can explicitly or implicitly indicate scheduling information, such as directly indicating the content of the scheduling information or indicating the index corresponding to the scheduling information. The scheduling information can be the scheduling information of the PDSCH carrying the SIB. The terminal can directly determine the resource location of the PDSCH carrying the SIB based on the scheduling information indicated by the first broadcast channel, and thus can receive the PDSCH carrying the SIB at the determined resource location.

[0188] The terminal can also determine the resource location of the PDSCH carrying the SIB based on the resource location of the first broadcast channel. The resource location of the first broadcast channel and the resource location of the PDSCH carrying the SIB are related, such as having a certain offset between them or a fixed mapping relationship.

[0189] Taking the first broadcast channel as PBCH as an example, the terminal can directly determine the resource location of the PDSCH carrying the SIB based on the scheduling information indicated by the PBCH, or it can determine the resource location of the PDSCH carrying the SIB based on the resource location of the PBCH.

[0190] The first target object can also be a synchronization block, which is a functional block used for synchronization, such as a synchronization signal block (SSB), or other synchronization blocks with the same or similar functions as the SSB. The synchronization block can explicitly or implicitly indicate scheduling information, such as directly indicating the content of the scheduling information or indicating the index corresponding to the scheduling information. The scheduling information indicated by the synchronization block can be scheduling information indicated by synchronization signals (e.g., PSS, SSS) within the synchronization block. For example, the synchronization signals in the synchronization block carry the scheduling information through a sequence, or the resources of the synchronization signals in the synchronization block correspond to the resources of the PDSCH carrying the SIB. Alternatively, the scheduling information indicated by the synchronization block can also be scheduling information indicated by the PBCH within the synchronization block, which can be the scheduling information of the PDSCH carrying the SIB. The terminal can determine the resource location of the PDSCH carrying the SIB based on the scheduling information indicated by the synchronization block, and thus can receive the PDSCH carrying the SIB at the determined resource location.

[0191] The terminal can also determine the resource location of the PDSCH carrying the SIB based on the resource location of the synchronization block. The resource location of the synchronization block and the resource location of the PDSCH carrying the SIB are related, for example, they have a certain offset or a fixed mapping relationship. The resource location of the synchronization block can be the resource location of the synchronization signal (e.g., PSS, SSS) in the synchronization block, or it can be the resource location of the PBCH in the synchronization block.

[0192] It should be noted that the first broadcast channel may be included in the synchronization block or it may be an independent broadcast channel. For example, if the synchronization block includes the first broadcast channel, the terminal can determine the resource location of the PDSCH carrying the SIB based on the scheduling information indicated by the first broadcast channel or the scheduling information indicated by the synchronization block. The scheduling information indicated by the first broadcast channel and the scheduling information indicated by the synchronization block may be the same, or the scheduling information indicated by the first broadcast channel may be considered as the scheduling information indicated by the synchronization block. The terminal can also determine the resource location of the PDSCH carrying the SIB based on the resource location of the first broadcast channel or the resource location of the synchronization block. The resource location of the first broadcast channel may also be considered as the resource location of the synchronization block.

[0193] The terminal can also determine the resource location of the PDSCH carrying the SIB based on the scheduling information indicated by the first target object and the resource location of the first target object. For example, the scheduling information indicates the offset between the resource location of the first target object and the resource location of the PDSCH carrying the SIB. The terminal can determine the resource location of the PDSCH carrying the SIB based on the offset and the resource location of the first target object.

[0194] The SIB can be System Information Block 1 (SIB1) or other SIBs.

[0195] In embodiments of this disclosure, the network-side device sends a first target object, and the terminal can determine the resource location of the PDSCH carrying the SIB based on the scheduling information indicated by the first target object and / or the resource location of the first target object. The first target object may be a first broadcast channel and / or a synchronization block. This scheme simplifies the process of the terminal determining the resource location of the PDSCH carrying the SIB, and also simplifies the process of the network-side device sending the PDSCH carrying the SIB, which is beneficial for both the terminal and the network-side device to save power consumption.

[0196] In some embodiments, the scheduling information includes at least one of the following:

[0197] (1) First offset information, which is the offset information between the resource location of the first target object and the resource location of the PDSCH carrying the SIB. The terminal can determine the resource location of the PDSCH carrying the SIB based on the first offset information and the resource location of the first target object.

[0198] (2) Periodic transmission configuration information of the PDSCH carrying the SIB; the first target object may also indicate the periodic transmission configuration information of the PDSCH carrying the SIB. In some embodiments, the periodic transmission configuration information includes at least one of the following:

[0199] The value of the transmission period of the PDSCH carrying the SIB;

[0200] The starting position of the PDSCH carrying the SIB within the transmission cycle;

[0201] The end position of the PDSCH carrying the SIB within the transmission cycle;

[0202] The transmission duration of the PDSCH carrying the SIB within the transmission cycle;

[0203] The number of transmissions of the PDSCH carrying the SIB within a transmission cycle;

[0204] The first index is an index corresponding to the periodic transmission configuration information. The periodic transmission configuration information corresponding to the first index may include one or more of the above configuration information contents. At least one of the above periodic transmission configuration information can be determined based on the first index.

[0205] (3) The temporal resource location of the PDSCH carrying the SIB; the first target object can also indicate the temporal resource location of the PDSCH carrying the SIB, so that the terminal can directly determine the temporal resource location of the PDSCH carrying the SIB according to the indication of the first target object. The temporal resource location can be the absolute time information of the PDSCH carrying the SIB. For example, at least one of the following: the start time unit of the PDSCH carrying the SIB, the time unit length of the PDSCH carrying the SIB, etc. The start time unit is, for example, the starting subframe and / or the starting time slot and / or the starting symbol of the PDSCH carrying the SIB, etc., and the time unit length can be the number of subframes and / or the number of time slots and / or the number of symbols occupied by the PDSCH carrying the SIB, etc.

[0206] (4) Frequency domain resource location of the PDSCH carrying the SIB. The first target object can also indicate the frequency domain resource location of the PDSCH carrying the SIB, so that the terminal can directly determine the frequency domain resource location of the PDSCH carrying the SIB based on the indication of the first target object. The frequency domain resource location can be the absolute frequency domain information of the PDSCH carrying the SIB, such as at least one of the following: the number of subcarriers occupied by the PDSCH carrying the SIB, the starting position of the occupied subcarriers, the number of occupied RBs, the starting position of the occupied resource block, etc.

[0207] In some embodiments, the scheduling information may include, in addition to one or more of the information described above, at least one of the following: VRB-PRB mapping information, modulation indication information, and redundancy version information. One or more of the above scheduling information can be indicated by different fields in the MIB.

[0208] In some embodiments, the first target object indicates the first offset information in a manner that includes at least one of the following:

[0209] The first target object indicates the value of the first offset information;

[0210] The first target object carries a third index, which is the index corresponding to the first offset information.

[0211] In this embodiment, the first target object can explicitly or implicitly indicate the first offset information, such as directly indicating the value of the first offset information or indicating the index corresponding to the first offset information. For example, the network pre-configures or the protocol predefines multiple indices corresponding to offset information. The network-side device indicates the target index in the first target object. The terminal can determine the corresponding first offset information based on the target index. Based on the first offset information and the resource location of the first target object, the resource location of the PDSCH carrying the SIB can be determined.

[0212] In some embodiments, the first offset information includes: frequency domain offset information and / or time domain offset information;

[0213] The frequency domain offset information includes at least one of the following:

[0214] The number of frequency domain units between the first target object and the CRB;

[0215] The number of frequency domain units between the first target object and the PDSCH carrying the SIB;

[0216] The time-domain offset information includes the number of time units between the first target object and the PDSCH carrying the SIB.

[0217] In this embodiment, the first offset information may be time-domain offset information and / or frequency-domain offset information. The first target object indicating frequency-domain offset information may indicate the number of frequency-domain cells between the first target object and the CRB, or it may indicate the number of frequency-domain cells between the first target object and the PDSCH carrying the SIB. The frequency-domain cells include at least one of the following: subcarriers and RBs. The frequency-domain offset information may be directly displayed in the first target object, or it may be determined by the index indicated by the first target object.

[0218] The first target object indicates the number of time units between the first target object and the PDSCH carrying the SIB. The time unit includes at least one of the following: time slot, symbol, frame, or subframe. This time offset can be indicated by display within the first target object or determined by an index indicated by the first target object.

[0219] In some embodiments, when the first target object is the first broadcast channel, the master information block (MIB) carried by the first broadcast channel contains at least a portion of the scheduling information; and / or, the physical layer information of the first broadcast channel contains at least a portion of the scheduling information.

[0220] In this embodiment, the scheduling information of the PDSCH carrying the SIB can be included in the MIB, or in the physical layer information, or some scheduling information can be included in the MIB and the rest in the physical layer information. For example, if the first target object is the PBCH, the scheduling information of the SIB PDSCH can be included in the PBCH's MIB, or in the PBCH's physical layer information, or some scheduling information can be included in both the MIB and the PBCH's physical layer information.

[0221] In some embodiments, the first field in the MIB contains at least a portion of the scheduling information; the first field includes at least one of the following: a system frame number field; a physical downlink control channel (PDCCH) configuration information field; and a subcarrier common interval field.

[0222] In this scenario, the first field in the MIB has different interpretations depending on whether the network is in power-saving or non-power-saving mode. For example, in non-power-saving mode, the pdcch-ConfigSIB1 field in the MIB indicates the common control resource set (CORESET) and common search space information of the SIB1 PDCCH, while the system frame number field indicates partial information about the system frame number of the cell. When the network-side equipment is in power-saving mode, the pdcch-ConfigSIB1 field and system frame number field in the MIB can be reinterpreted to indicate the scheduling information of the PDSCH carrying SIB1.

[0223] In some embodiments, the resource location of the first target object is mapped to the resource location of the PDSCH carrying the SIB. This mapping relationship can be agreed upon by a protocol, predefined, or configured by the network side. For example: if the resource location of the first target object is A, the resource location of the PDSCH carrying the SIB is N time slots after A; if the resource location of the first target object is B, the resource location of the PDSCH carrying the SIB is N time slots after B. The terminal can directly determine the resource location of the PDSCH carrying the SIB based on the resource location of the first target object and the mapping relationship.

[0224] In some embodiments, the first target object and the PDSCH carrying the SIB have a first resource configuration mode, and the resource location of the PDSCH carrying the SIB is related to the first resource configuration mode.

[0225] In some embodiments, the first resource configuration mode includes one of the following:

[0226] The first target object overlaps with the time domain resources of the PDSCH carrying the SIB, but the frequency domain resources do not overlap.

[0227] The first target object overlaps with the frequency domain resources of the PDSCH carrying the SIB, but their time domain resources do not overlap.

[0228] The first target object does not overlap with the time domain resources and frequency domain resources of the PDSCH carrying the SIB.

[0229] In this embodiment, the resource location of the first target object and the resource location of the PDSCH carrying the SIB satisfy the first resource configuration mode. For example, frequency division, time division, or a combination of frequency and time division modes. Specifically, in frequency division mode, the time-domain resources of the first target object and the PDSCH carrying the SIB overlap, but their frequency-domain resources do not overlap. For example, the scheduling information may include the frequency-domain offset between the first target object and the PDSCH carrying the SIB, allowing the terminal to determine the frequency-domain location of the PDSCH carrying the SIB based on the frequency-domain location of the first target object and the frequency-domain offset.

[0230] In time-division mode, the frequency domain resources of the first target object and the PDSCH carrying the SIB overlap, but the time domain resources do not overlap. For example, the scheduling information may include the time domain offset between the first target object and the PDSCH carrying the SIB. The terminal can determine the time domain position of the PDSCH carrying the SIB based on the time domain position of the first target object and the time domain offset.

[0231] In frequency division and time division mode, the time domain resources of the first target object and the PDSCH carrying the SIB do not overlap and the frequency domain resources do not overlap. For example, the scheduling information may include the time domain offset and frequency domain offset between the first target object and the PDSCH carrying the SIB. The terminal can determine the time domain position of the PDSCH carrying the SIB based on the time domain position of the first target object and the time domain offset, and determine the frequency domain position of the PDSCH carrying the SIB based on the frequency domain position of the first target object and the frequency domain offset.

[0232] In some embodiments, the first target object carries a second index, which is an index of a first resource configuration pattern between the first target object and the PDSCH carrying the SIB.

[0233] In this embodiment, the first target object carries a second index. This can be understood as the first target object containing or indicating the value of the second index, or the first target object implicitly indicating the second index through a predefined or preconfigured method. For example, a target field indicating 00 in the first target object means the second index is 0, a target field indicating 01 means the second index is 1, a target field indicating 11 means the second index is 2, and so on. For example, if the first target object is a PBCH, the time-domain / frequency-domain offset between the PBCH and the SIB1PDSCH can be a fixed value agreed upon by the protocol, that is, the pattern between the two is fixed. In the case of multiple first resource configuration modes, the index indicating the pattern in the PBCH can also be understood as the PBCH indicating that the scheduling information of the SIB PDSCH is specifically an index of a pattern.

[0234] In some embodiments, the first target object carries first indication information, which indicates that the first target object is associated with a PDSCH carrying an SIB, and / or indicates that the first target object does not have an associated PDSCH carrying an SIB.

[0235] In this embodiment, the first target object carries first indication information, such as fields within the first target object indicating the first indication information or related information such as an index of the first indication information, or the first target object having an association with the first indication information. This first indication information is used to indicate whether the current first target object is associated with a PDSCH carrying an SIB. The first target object may be associated with one or more PDSCHs carrying SIBs, in which case the relevant information of the first target object can be used to determine the resource location of the associated PDSCH carrying the SIB. The first target object may also not have an associated PDSCH carrying an SIB; in this case, the relevant information of the first target object cannot be used to determine the resource location of the PDSCH carrying the SIB. This can also be understood as not every resource location of a first target object can be combined with offset information to determine the resource location of a PDSCH carrying an SIB. There is a many-to-one relationship between the first target object and the PDSCH carrying the SIB. It can be understood that the first target object carrying the first indication information can also indicate that X first target objects are associated with one PDSCH carrying an SIB.

[0236] In some embodiments, when the network-side device is in an energy-saving state, and / or when the terminal sends an uplink wake-up signal (WUS) to the network-side device, the relevant information of the first target object is used to determine the resource location of the PDSCH carrying the SIB.

[0237] In this embodiment, when the network-side device is in an energy-saving state, the terminal can determine the resource location of the PDSCH carrying the SIB based on the relevant information of the first target object sent by the network-side device. For example, if the network-side device is in an energy-saving state, the first target object sent carries the scheduling information of the PDSCH carrying the SIB, or it is assumed that the resource location of the first target object sent by the network-side device at this time can be used to determine the resource location of the PDSCH carrying the SIB.

[0238] In some embodiments, before sending the first target object to the terminal, the method further includes:

[0239] The receiving terminal sends an uplink WUS, the uplink WUS carrying first information, the first information being used to request at least one of the following:

[0240] Network-side equipment sends the first broadcast channel and the PDSCH carrying the SIB;

[0241] Network-side devices send synchronization blocks and PDSCH carrying SIBs;

[0242] The network-side device sends the first broadcast channel;

[0243] Network-side devices send synchronization blocks;

[0244] The network-side device sends the PDSCH carrying the SIB.

[0245] In this embodiment, the terminal sends an uplink WUS to the network-side device, which can be used to request the network-side device to send a first target object and / or the PDSCH carrying the SIB. It should be noted that the first target object triggered by the terminal sending the uplink WUS request may be different from the first target object of the PDSCH carrying the SIB determined by the terminal. For example: the uplink WUS is used to trigger the network-side device to send a first broadcast channel and the PDSCH carrying the SIB; the terminal can determine the resource location of the PDSCH carrying the SIB based on the relevant information of the synchronization block. Another example: the uplink WUS is used to trigger the network-side device to send a synchronization block; the terminal can determine the resource location of the PDSCH carrying the SIB based on the first broadcast channel. Yet another example: the first broadcast channel may be included within the synchronization block; the terminal sends an uplink WUS to trigger the network-side device to send the first broadcast channel; the terminal can determine the resource location of the PDSCH carrying the SIB based on the relevant information of the first broadcast channel, or it can determine the resource location of the PDSCH carrying the SIB based on the relevant information of the synchronization block.

[0246] In some embodiments, the first information is carried by sequence information of the uplink WUS, and / or, the first information is carried by resource information of the uplink WUS. Specifically, different sequence information can be used to carry first information for requesting different content, and / or different resource information can be used to carry first information for requesting different content.

[0247] In embodiments of this disclosure, the network-side device sends a first target object, and the terminal can determine the resource location of the PDSCH carrying the SIB based on the scheduling information indicated by the first target object and / or the resource location of the first target object. The first target object may be a first broadcast channel and / or a synchronization block. This scheme simplifies the process of the terminal determining the resource location of the PDSCH carrying the SIB, and also simplifies the process of the network-side device sending the PDSCH carrying the SIB, which is beneficial for both the terminal and the network-side device to save power consumption.
