Description

TECHNICAL FIELD

[0001] The present application relates to the wireless technical field, in particular to an information acquisition method, a sending method, an apparatus, a terminal, a device, a medium and a program product. BACKGROUND

[0002] Currently, in order to ensure network energy saving, a mechanism of triggering system information block SIB1 on demand is discussed in the existing communication standard. In a network energy-saving (NES) cell scenario, the SIB1 of the cell is not periodically sent (or broadcast) by default. 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 sends (or broadcasts) 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 send 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 sends the SIB1.

[0003] 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 sends 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.

[0111] To make the technical problems, technical solutions and advantages of the present application clearer, the following will be described in detail with reference to the accompanying drawings and specific embodiments.

[0112] The terms "first", "second", etc. in the specification and claims of the present application 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 application 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 associated objects before and after.

[0113] To make the technical solutions of the present application clearer, the following describes the background art related to the technical solutions of the present application.

[0114] At present, system information is divided into the following two categories:

[0115] 1) Master system information block, also known as SIB1, mainly used to store the most important necessary information in the entire network. Among them:

[0116] a) Scheduling occasion of SIB1: SIB1 is scheduled by PDCCH sent on resource set CORESET0 / CSS0 (or Type0-CSS), which is sent with a period of 20ms, and the specific scheduling occasion is indicated by the field in the Master Information Block (MIB);

[0117] b) SIB1 includes the SI-SchedulingInfo field, which indicates the relevant information of other SIBs, including the following two IEs:

[0118] Tag value valueTag: indicates the current version number of the SIB. When the terminal device detects a change in the value of this IE, it means that the corresponding SIB information has changed;

[0119] areasopce and systemInformationAreaID: When configured, it indicates which area this SIB belongs to. The SIB information of all cells in one area is the same. When not configured, the terminal device considers that this SIB is only valid for the current cell;

[0120] 2) Other SIBs: including the remaining various system information blocks (i.e., SIB2-SIB24):

[0121] a) Transmission timing of other SIBs: the network device configures the 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 the 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 the time domain. Each SIB message is periodically transmitted in the corresponding SI-window. When the position of an SI-window in the time domain is determined, the condition for the system frame SFN in which the SI-window is located is:

[0122]

[0123] wherein T is the period of the relevant SIB message, configured by the signaling parameter SI-Periodicity;

[0124] n is the order number corresponding to the entry of the signaling SI-SchedulingInfo in the signaling message list: SchedulingInfoList;

[0125] w is the length of the Si-Window, provided by the signaling parameter: SI-WindowLength;

[0126] N is the number of slots in one system frame;

[0127] In addition, the starting slot Slot a of the SI-window can be determined in the following way:

[0128] a = ((n-1) x w) mod N.

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

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

[0131] SI-windowlength: indicates the SIB reception window length (w);

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

[0133] b) The network device configures the parameter si-BroadcastStatus for each SIB. When the parameter is set to broadcast, the terminal device can directly detect the SIB according to the periodic configuration in the corresponding time domain position; if the parameter is set to non-broadcast, the terminal device needs to send an uplink signal 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 scheduled by system information-radio network temporary identity (SI-RNTI) scrambled DCI, 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] Bit field System information indicator 0 SIB1 [9, TS 38.331, Clause 5.2.1] 1 SI message message [9, TS 38.331, Clause 5.2.1]

[0137] 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:

[0138] The stored system information is more than 3 hours;

[0139] The network device indicates that the system information has changed through paging DCI.

[0140] The network device sets the short message indicator field (Short Messages Indicator) in the paging DCI to "10" or "11" to indicate that the system information has changed. The specific format of this field is as follows:

[0141]

[0142]

[0143] In addition, the first bit and the second bit in the short information field in the paging DCI indicate 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 this field is as follows:

[0144] Bit Short message field 1 System information change indication 2 ETWS and CMAS indication 3 Stop paging monitoring indication 4 System information change indication in eDRX 5-8 Not used

[0145] Further, the network device configures the terminal device with a modification period, which takes the system radio frame with SFN=0 as the starting point and has an integer multiple of the paging cycle. Specifically, the multiple of the paging cycle is indicated by the field modificationPeriodCoeff.

[0146] For the idle state terminal, it detects the paging DCI in each paging cycle, and for the connected state 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.

[0147] Currently, the mechanism of triggering SIB1 on demand is being discussed, the main purpose of which 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.

[0148] In one way, the terminal device only camps on the cell (or called Anchor Cell, or anchor cell) that periodically sends (or broadcasts) SIB1 (or called non-broadcasts), and only sends an uplink trigger signal to obtain SIB1 of the NES cell when there is a demand, and accesses and / or performs data transmission based on the NES cell.

[0149] In the lower, one possible specific implementation in this scenario is that the SIB1 of one or more NES cells (or called second cells) is sent on the cell (or called anchor cell) that periodically sends SIB1. Correspondingly, the terminal device sends an uplink trigger signal in the anchor cell to trigger the SIB1 of the corresponding NES cell. In this way, the NES cell can not send its own SIB1 at all, thereby achieving better energy saving effect.

[0150] However, since the terminal device resides on the anchor cell, when the SIB1 of the NES cell changes, the terminal device cannot acquire the SIB1 change of the NES cell in real time according to the prior art, which can cause the terminal device and the network to be misaligned in understanding the SIB1 of the NES cell, thereby affecting the transmission performance and transmission efficiency.

[0151] To solve the above technical problem, the embodiment of the present application provides an information acquisition method, wherein the terminal device can acquire the update indication of the SIB1 of at least one second cell on the first cell, so that the terminal device can acquire the change of the SIB1 of the second cell on the first cell in real time, thereby avoiding the terminal device and the network being misaligned in understanding the SIB1 of the second cell (NES cell), and affecting the transmission performance and transmission efficiency.

[0152] As shown in Fig. 1, the embodiment of the present application provides an information acquisition method, which is optionally executed by a terminal device, comprising: Figure 1

[0153] S110, receiving first information on the first cell, wherein the first information is used to indicate the update of the system information block (SIB1) of at least one second cell; wherein the SIB1 of the at least one second cell is non-broadcast information.

[0154] The information acquisition method provided by the embodiment of the present application is applied to the terminal device residing on the first cell, and when the SIB1 of the second cell changes, the terminal device needs to acquire the change of the SIB1 of the second cell in time, so as to enable the terminal device and the network to be aligned in understanding the system information of the second cell. By using the method provided by the embodiment, the terminal device can receive the change indication of the SIB1 of at least one second cell on the first cell, so that when the SIB1 of the second cell changes, the terminal device can acquire the change of the SIB1 of the second cell on the first cell in real time, so that the terminal device and the network are aligned in understanding the change state of the SIB1 of the second cell, thereby avoiding affecting the transmission performance and transmission efficiency.

[0155] Optionally, in one embodiment, the first cell includes but is not limited to only the anchor cell of the terminal device, and the second cell includes but is not limited to only the NES cell. By using this embodiment, when the terminal device resides on the anchor cell, the change of the SIB1 of the NES cell can be acquired in real time.

[0156] It should be noted that in the embodiment of the present application, the system information block (SIB1) mentioned can also be the remaining minimum system information (RMSI).

[0157] ​It should be noted that the SIB1 of the second cell is non-broadcast information, and it can also be understood that the SIB1 of the second cell is not periodically transmitted information, or the SIB1 of the second cell is on-demand triggered information.

[0158] In the embodiment of the application, the first information is used to indicate the update of the SIB1 of the at least one second cell, and includes one or more of the following:

[0159] The first information is used to indicate that the SIB1 of the at least one second cell exists update.

[0160] The first information is used to indicate the update state of the SIB1 of the at least one second cell, that is, whether there is an update.

[0161] The first information is used to indicate the second cell in which the SIB1 exists update.

[0162] In the embodiment of the application, optionally, the first information includes at least one of the following:

[0163] Physical Radio Network Temporary Identifier (P-RNTI) scrambled Downlink Control Information (DCI);

[0164] Paging Early Indication-Radio Network Temporary Identifier (PEI-RNTI) scrambled DCI.

[0165] In the embodiment of the application, in an implementation, optionally, the first information is P-RNTI scrambled DCI, and the method further includes:

[0166] 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.

[0167] In this implementation, the base station transmits 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.

[0168] Optionally, the first value is but not limited to only "00". With this embodiment, the "00" value of the short message indication field in the P-RNTI scrambled DCI is used to indicate the update of the SIB1 of the at least one second cell. In this way, in the case that the short message indication field of the P-RNTI scrambled DCI received by the terminal is "00", it is determined that the P-RNTI scrambled DCI is used to indicate the update of the SIB1 of the at least one second cell; or in other words, when the short message indication field of the P-RNTI scrambled DCI received by the terminal is "00", the terminal determines that the DCI indicates the update of the SIB1 of the at least one second cell; or in other words, the value "00" of the short message indication field 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.

[0169] Another embodiment, optionally, the "00" value of the short message indication field in the P-RNTI scrambled DCI is also used to indicate that the DCI is used to schedule a paging message, and / or the P-RNTI scrambled DCI is also used to indicate the update of the SIB1 of the first cell.

[0170] In the embodiments of the present application, optionally, the method further comprises:

[0171] 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.

[0172] 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 plurality of second bits of the short message field have a one-to-one correspondence relationship with the cell identifiers of the second cells; optionally, the terminal can further receive the first configuration information sent by the base station, and the first configuration information can include the cell identifiers of the at least one second cell and / or the mapping relationship between the plurality of second bits of the short message field and the at least one second cell. Optionally, the mapping relationship between the plurality of second bits of the short message field and the at least one second cell can be determined according to the arrangement order of the plurality of second bits of the short message field and the arrangement order of the cell identifiers of the plurality of second cells in the first configuration information, so as to determine which second cell corresponds to the update of the system information indicated by the plurality of second bits of the short message field.

[0173] 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".
