[0001] Cross-reference to Related Applications

[0002] The present disclosure claims priority from Chinese Patent Application No. 202410982797.3 filed on July 22, 2024 in China, the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0003] The present disclosure relates to the field of wireless technology, and particularly refers to an information acquisition method, a sending method, a device, a terminal, an equipment, a medium and a program product. BACKGROUND

[0004] Currently, in order to ensure network energy saving, a mechanism of triggering system information block (SIB) 1 on demand is being discussed in existing communication standards. In a network energy-saving (NES) cell scenario, by default, the SIB1 of the cell is not periodically transmitted (or broadcast transmitted). A terminal device can only camp on a cell (which can also be referred to as an anchor cell or a non-NES cell, such as a first cell) that periodically transmits (or broadcast transmits) the SIB1. When the terminal device has a data transmission requirement, the terminal device sends an uplink trigger signal (such as a physical random access channel (PRACH) signal) to enable the network device to transmit the SIB1 of the NES cell (such as a second cell), and access and perform data transmission based on the NES cell. In some cases, the terminal device can also directly acquire the system information block SIB1 of the NES cell on the cell (which can also be referred to as an anchor cell or a non-NES cell, such as a first cell) that periodically transmits the SIB1.

[0005] However, in some cases, the system information block SIB1 of the NES cell can dynamically change. According to the mechanism in the prior art, when the terminal device camps on the cell that periodically transmits the SIB1, the terminal device cannot acquire the changed NES cell system information in real time. This will cause the terminal device and the network to be out of alignment in understanding the SIB1 of the NES cell, thereby affecting the transmission performance and transmission efficiency.

[0113] In order to make the technical problems, technical solutions and advantages of the present disclosure clearer, the following will be described in detail with reference to the drawings and specific embodiments.

[0114] The terms "first", "second", and the like in the specification and claims of the present disclosure are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present disclosure can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second" are generally of a kind and do not limit the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally represents an "or" relationship between the objects before and after it.

[0115] In order to clearly illustrate the technical solutions of the present disclosure, the following describes the background art related to the technical solutions of the present disclosure.

[0116] At present, system information is divided into the following two categories:

[0117] 1) Master system information block, also known as SIB1, mainly used to store the most important necessary information in the entire network. Among them:

[0118] a) SIB1 transmission occasion: SIB1 is scheduled by the physical downlink control channel (PDCCH) transmitted on the resource set CORESET0 / CSS0 (or Type0-CSS), which is transmitted every 20ms, and the specific transmission occasion is indicated by the field in the master information block (MIB); CORESET is a control resource set, and CSS is a common search space;

[0119] b) SIB1 includes SI-SchedulingInfo field, which indicates the relevant information of other SIBs, including the following two IEs:

[0120] Tag value valueTag: indicates the current version number of the SIB. When the terminal device detects that the IE value changes, it means that the corresponding SIB information has changed;

[0121] Area scope areascope and system information block area identifier systemInformationAreaID: When configured, it indicates which area the SIB belongs to. The SIB information of all cells in one area is the same. When not configured, the terminal device considers that the SIB is only valid for the current cell;

[0122] 2) Other SIBs: including the remaining various system information blocks (that is, SIB2-SIB24):

[0123] a) Transmission occasion of other SIBs: network device configures parameter schedulingInfoList, and the terminal device determines the time window for transmitting the corresponding SIB message according to the SIB information configured in the parameter. Specifically, the parameter includes field SI-window, and the lengths of all SIB messages SI-window are the same. Each SIB message is associated with an SI-window, and the SI-windows of different SIB messages cannot overlap in time domain. Each SIB message is periodically transmitted in the corresponding SI-window. When the position of an SI-window in time domain is determined, for the system frame (System frame number, SFN) in which the SI-window is located, the condition is:

[0124] Wherein, T is the period of the relevant SIB message, which is configured by signaling parameter SI-Periodicity;

[0125] n is the order number corresponding to the entry of the signaling SI-SchedulingInfo in the signaling message list: SchedulingInfoList;

[0126] w is the length of Si-Window, which is provided by the signaling parameter: SI-WindowLength;

[0127] N is the number of slots in a system frame;

[0128] In addition, the starting slot Slot a of the SI-window can be determined in the following way: a = ((n-1) x w) mod N.

[0129] According to the above, for each SIB, the following parameters are included:

[0130] SI-periodicity, indicating the transmission period (N) of the current SIB;

[0131] SI-windowlength: indicating the SIB receiving window length (w);

[0132] According to the number of elements in schedulingInfoList, the value of n is determined (for example, SIB2 corresponds to n = 1, SIB3 corresponds to n = 2).

[0133] b) The network device configures the parameter si-BroadcastStatus for each SIB. When this parameter is set to broadcast, the terminal device can directly detect the SIB according to the period configuration in the corresponding time domain position; if the parameter is set to non-broadcast, the terminal device needs to send uplink signals on demand to trigger the transmission of the corresponding SIB;

[0134] c) When the information of a certain SIB changes, the valueTag value in SIB1 also changes. Correspondingly, after the terminal device receives the system information update indication, it will first detect SIB1, and then further detect the corresponding SIB after finding the corresponding tag change.

[0135] 3) All system information blocks are scrambled by system information - radio network temporary identity (SI-RNTI) downlink control information (DCI) scheduling, which contains the system information indicator System information indicator field. The value of this field is 0, which represents scheduling transmission as SIB1, and the value is 1, which represents scheduling transmission as other SI, as shown in the following table:

[0136] Based on the above configuration method of system information, in some cases, the terminal device needs to update the system information it has stored, for example:

[0137] The stored system information has exceeded 3 hours;

[0138] The network device indicates that the system information has changed through paging DCI.

[0139] The network device sets the short message indicator field in the paging DCI to "10" or "11" to indicate that the system information has changed. The specific format of the field is as follows:

[0140] In addition, the network device indicates in the first bit and the second bit in the short message field in the paging DCI which type of SIB has changed. Specifically, the first bit indicates that the system information of SIBs other than SIB6-SIB8 has changed, and the second bit indicates that the system information of SIB6-SIB8 has changed. The specific format of the field is as follows:

[0141] ETWS is the Earthquake and Tsunami Warning System;

[0142] CMAS is the Commercial Mobile Alert Service;

[0143] eDRX is the extended DRX cycle.

[0144] Further, the network device configures the terminal device with a modification period, which starts at the system radio frame with SFN=0 and has an integer multiple of the paging cycle. Specifically, the multiple of the paging cycle is indicated by the field modificationPeriodCoeff.

[0145] For an idle terminal, it detects the paging DCI in each paging cycle. For a connected terminal, it detects the paging DCI at least once in each modification period. After the terminal device receives the indication of the system message update in a modification period, it starts to detect the corresponding SIB at the start time of the next modification period.

[0146] Currently, the mechanism of triggering SIB1 on demand is being discussed. The main purpose is to not periodically send (or broadcast) SIB1 in the NES cell scenario under normal circumstances, thereby saving energy. When the terminal device has a demand, it can send an uplink trigger signal (PRACH signal) to enable the network device to send SIB1 of the NES cell.

[0147] In one mode, the terminal device only camps on a cell (or referred to as an anchor cell) that periodically transmits (or referred to as broadcast transmission) SIB1 (or referred to as non-broadcast transmission), and only transmits an uplink trigger signal to acquire SIB1 of the NES cell when there is a demand, and accesses and / or performs data transmission based on the NES cell.

[0148] In a lower mode, one possible implementation of the scenario is that SIB1 of one or more NES cells (or referred to as second cells) is transmitted on a cell (or referred to as an anchor cell) that periodically transmits SIB1. Correspondingly, the terminal device transmits an uplink trigger signal to trigger SIB1 of the corresponding NES cell in the anchor cell. In this mode, the NES cell can not transmit its own SIB1 at all, thereby achieving better energy saving effect.

[0149] However, since the terminal device camps on the anchor cell, when the SIB1 of the NES cell changes, according to the prior art, the terminal cannot acquire the SIB1 change of the NES cell in real time, which may cause the terminal device and the network to be out of alignment in understanding the SIB1 of the NES cell, thereby affecting the transmission performance and transmission efficiency.

[0150] To solve the above technical problems, the embodiments of the present disclosure provide an information acquisition method, so that the terminal can acquire the update indication of the SIB1 of the at least one second cell on the first cell, so that the terminal can acquire the change of the SIB1 of the second cell on the first cell in real time, thereby avoiding the problem that the terminal and the network are out of alignment in understanding the SIB1 of the corresponding second cell (NES cell), thereby affecting the transmission performance and transmission efficiency.

[0151] As shown in FIG. 1, the flowchart of the information acquisition method according to the embodiments of the present disclosure is shown. Optionally, the method according to the embodiments is executed by the terminal, and includes the following steps.

[0152] S110, receiving first information on a first cell, the first information being used to indicate an update of a system information block SIB1 of at least one second cell; wherein the SIB1 of the at least one second cell is non-broadcast information.

[0153] The information acquisition method provided in the embodiments of the present disclosure is applied to a terminal camping on a first cell. When the SIB1 of a second cell changes, the terminal needs to acquire the change of the SIB1 of the second cell in a timely manner, so as to enable the terminal and the network to align the understanding of the system information of the second cell. By using the method provided in the embodiments, the terminal can receive the change indication of the SIB1 of at least one second cell on the first cell. In this way, when the SIB1 of the second cell changes, the terminal can acquire the change of the SIB1 of the second cell in real time on the first cell, so that the understanding of the terminal and the network on the change of the SIB1 of the second cell is kept aligned, and the transmission performance and transmission efficiency are avoided from being affected.

[0154] Optionally, in an embodiment, the first cell includes, but is not limited to, only an anchor cell capable of camping on the terminal, and the second cell includes, but is not limited to, only a NES cell. By using this embodiment, in the case that the terminal camps on the anchor cell, the change of the SIB1 of the NES cell can be obtained in real time.

[0155] It should be noted that in the embodiments of the present disclosure, the system information block SIB1 mentioned can also be Remaining Minimum System Information (RMSI).

[0156] It should be noted that the SIB1 of the second cell is non-broadcast information, and can also be understood as that the SIB1 of the second cell is not periodically transmitted information, or the SIB1 of the second cell is on-demand triggered information.

[0157] In the embodiments of the present disclosure, the first information is used to indicate the update of the SIB1 of at least one second cell, and includes one or more of the following:

[0158] The first information is used to indicate that the SIB1 of at least one second cell exists update;

[0159] The first information is used to indicate the update state of the SIB1 of at least one second cell, that is, whether there is update;

[0160] The first information is used to indicate the second cell in which the SIB1 exists update.

[0162] Physical Radio Network Temporary Identifier (P-RNTI) scrambled Downlink Control Information (DCI);

[0163] The DCI is scrambled by a paging early indication-radio network temporary identifier (PEI-RNTI).

[0164] In one embodiment of the present disclosure, the first information is DCI scrambled by a P-RNTI, and the method further includes:

[0165] The short message indication field of the first information is a first value, and the terminal determines that the first information is used to indicate the update of the SIB1 of the at least one second cell according to the first value.

[0166] In this embodiment, the base station sends the first information on the first cell, and the short message indication field of the first information is a first value, which is used to indicate the update of the SIB1 of the at least one second cell.

[0167] Optionally, the first value is but not limited to only "00". In this embodiment, the "00" value of the short message indication field in the DCI scrambled by the P-RNTI is used to indicate the update of the SIB1 of the at least one second cell. In this way, when the terminal receives the DCI scrambled by the P-RNTI and the short message indication field of the DCI is "00", it is determined that the DCI is used to indicate the update of the SIB1 of the at least one second cell; or when the terminal receives the DCI scrambled by the P-RNTI and the short message indication field of the DCI is "00", the terminal determines that the DCI indicates the update of the SIB1 of the at least one second cell; or the short message indication field takes the value "00", which can also be understood as indicating that there is a field indicating the update of the SIB1 of the at least one second cell. Specifically, the field can be a short message field or a newly added field, such as one or more of the first indication field and the second indication field described below.

[0168] In another embodiment, the "00" value of the short message indication field in the DCI scrambled by the P-RNTI is also used to indicate that the DCI is used to schedule a paging message, and / or the DCI scrambled by the P-RNTI is also used to indicate the update of the SIB1 of the first cell.

[0169] In one embodiment of the present disclosure, the method further includes:

[0170] The terminal determines the update of the SIB1 of the at least one second cell according to the second bit of the short message field of the DCI.

[0171] Optionally, the second bit of the short message field can include one or more bits of the 5th bit to the 8th bit; optionally, the second bit of the short message field has a one-to-one correspondence with the cell identifier of the second cell; optionally, the terminal can further receive the first configuration information sent by the base station, wherein the first configuration information can include the cell identifier of the at least one second cell and / or the mapping relationship between the second bit of the short message field and the at least one second cell. Optionally, the mapping relationship between the second bit of the short message field and the at least one second cell can be determined according to the arrangement order of the second bit of the short message field and the arrangement order of the cell identifier of the second cell in the first configuration information, so as to determine the system information update indicated by the second bit of the short message field and which second cell.

[0172] It can be understood that in this embodiment, the short message indication field of the first indication information can take values of "10" or "11".

[0173] In this embodiment, optionally, the first information is the P-RNTI scrambled DCI, and the first information further includes the first indication field. The method further includes:

[0174] The terminal determines the system information update of the at least one second cell according to the first indication field, or in other words, the terminal determines the update state of the system information of the at least one second cell according to the first indication field.

[0175] Optionally, the method further includes:

[0176] determining the system information update of the at least one second cell according to the third bit of the first indication field,

[0177] or determining the system information update of the first cell group according to the third bit of the first indication field; wherein the first cell group includes the at least one second cell.

[0178] It should be noted that in the embodiments of the present disclosure, the first indication field mentioned does not include the short message field and the short message indication field. Optionally, compared with the P-RNTI scrambled DCI format in the prior art, the first indication field is a newly added field in the DCI.

[0179] Optionally, in the embodiments of the present disclosure, the third bit of the first indication field is any bit in the first indication field; in one implementation, each bit (the third bit) in the first indication field corresponds to at least one second cell, and is used to indicate the update state of the system information of the corresponding second cell; optionally, when the value indicated by the third bit is 0, it indicates that there is no update of SIB1 of the corresponding second cell; when the value indicated by the third bit is 1, it indicates that there is an update of SIB1 of the corresponding second cell. Of course, the correspondence between the value indicated by the third bit and the corresponding update state is only an example, and the specific implementation is not limited thereto.

[0180] As shown in FIG. 2, in the embodiments of the present disclosure, the correspondence between each bit in the first indication field and the cell identifier of the corresponding second cell is optional. The first indication field is a newly added bitmap in the DCI scrambled by the P-RNTI; optionally, the terminal also receives the first configuration information sent by the base station, and the first configuration information includes the cell identifier of at least one second cell; and / or the mapping relationship between the first indication field and the at least one second cell.

[0181] In one implementation, in combination with FIG. 2, the first configuration information includes a cell list, and the cell list includes the cell identifier of at least one second cell; optionally, the cell identifier includes but is not limited to only including the physical cell identifier (PCI). Optionally, according to the arrangement order of the plurality of cell identifiers in the cell list and the arrangement order of the plurality of bits in the first indication field, the cell identifier of the at least one second cell in the cell list and the plurality of bits in the first indication field have a one-to-one correspondence relationship. By corresponding the plurality of bits in the first indication field and the cell identifier of the second cell in the cell list, the corresponding mapping relationship can be determined.

[0182] For example, in combination with FIG. 2, according to the arrangement order of the plurality of cell identifiers in the cell list and the arrangement order of the plurality of bits in the first indication field, the first cell identifier (cell identifier 1) in the cell list corresponds to the first bit in the first indication field, the second cell identifier (cell identifier 2) in the cell list corresponds to the second bit in the first indication field, and so on, forming a one-to-one correspondence relationship between the cell identifier of the at least one second cell in the cell list and the plurality of bits in the first indication field.

[0183] In another implementation, each bit (third bit) in the first indication field corresponds to at least one first cell group, and is used to indicate the update state of the SIB1 of part or all of the second cells in the corresponding first cell group. Optionally, when the value indicated by the third bit is 0, it indicates that the SIB1 of the corresponding second cell in the first cell group is not updated; and when the value indicated by the third bit is 1, it indicates that the SIB1 of the corresponding second cell in the first cell group is updated.

[0184] In this implementation, the P-RNTI scrambled DCI further includes a second indication field. In this implementation, the method further includes:

Optionally, the first configuration information can further include the mapping relationship between the first cell group and at least one second cell, and the mapping relationship is used to indicate the corresponding relationship between the first cell group and the corresponding first cell.

[0192] Optionally, the first configuration information can further include the mapping relationship between each bit (third bit) in the first indication field and the first cell group. In one implementation, according to the arrangement order of the multiple bits in the first indication field and the arrangement order of the multiple first cell groups, the multiple bits in the first indication field and the multiple first cell groups have a one-to-one mapping relationship.

[0193] Optionally, each first cell group has a corresponding group identifier, and the network configures each first cell group with a corresponding group identifier and a cell list of corresponding second cells, which includes at least one cell identifier of the second cells. In this way, according to the arrangement order of the plurality of bits in the first indication field and the arrangement order of the group identifiers of the plurality of first cell groups, the plurality of bits in the first indication field and the plurality of first cell groups have a one-to-one mapping relationship. For example, the first bit in the first indication field corresponds to the first group identifier arranged in sequence, the second bit in the first indication field corresponds to the second group identifier arranged in sequence, and so on, forming a one-to-one mapping relationship between the plurality of bits in the first indication field and the plurality of first cell groups.

[0194] Optionally, the first configuration information can further include a mapping relationship between the second indication field and at least one of the second cells.

[0195] For example, the first bit in the second indication field has a mapping relationship with the Nth second cell of the first group identifier in the plurality of first cell groups, which is used to indicate that the Nth second cell in the cell group corresponding to the first group identifier has SIB1 update; wherein N is an integer greater than 1 and less than the total number of all second cells in the cell group; similarly, the second bit in the second indication field has a mapping relationship with the Mth second cell of the second group identifier in the plurality of first cell groups, which is used to indicate that the Mth second cell in the cell group corresponding to the second group identifier has SIB1 update; wherein M is an integer greater than 1 and less than the total number of all second cells in the cell group; and so on.

Of course, the correspondence between the value indicated here and the update state indicated by the corresponding value is only for illustration, and is not limited thereto.
