It should be noted that in the embodiment of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.

[0058] For better understanding, the relevant concepts and principles involved in the embodiments of this application are explained below.

[0059] In the NR system, system information is divided into two categories: MIB and SIB.

[0060] The MIB is the first system information received by the UE when a cell is started. It contains some basic system parameters. The main purpose of the MIB is to enable the UE to perceive the existence and basic characteristics of the cell and to conduct further protocol procedures such as random access and cell selection based on this information.

[0061] SIB refers to a message format used to transmit system information in the NR system, including cell broadcast information, Medium Access Control (MAC) configuration information, Transport MAC (TMAC) configuration information, Radio Link Control (RLC) configuration information, Packet Data Convergence Protocol (PDCP) configuration information, Radio Resource Management (RRM) configuration information, and location information. SIB information is a very important part of the NR system. It contains some key system parameters, such as frequency, cell identification code, and cell coverage. It is one of the main methods to transmit network status and quality information to wireless devices. The main purpose of SIB information is to enable UE to obtain necessary system information and participate in cell coordination, thereby realizing the various functions of the NR system. SIB information is divided into different types according to functional characteristics.

[0062] For a specific Pcell, SIB1 information needs to be sent periodically. Other System Information (OSI) can be sent via a request, where the requested configuration information is included in SIB1. The OSI request technology is implemented through the following steps:

[0063] The UE receives SIB1 and camps on cell A;

[0064] The UE sends an OSI SIB request to cell A based on the request configuration information in SIB1.

[0065] After receiving the request, the cell generates the corresponding OSI SIB message and sends it to the UE;

[0066] After receiving the requested OSI SIB message, the UE can parse the information therein and perform corresponding processing.

[0067] System information transmission in Hetnet scenario:

[0068] In the Hetnet scenario shown in Figure 1b, multiple capacity cells (also called hotspot cells, capacity cells) are located near a coverage cell. In the following scenario, even if there is no traffic within the coverage cell, the coverage cell and capacity cells A+B+C still need to periodically transmit synchronization signal blocks (SSBs) and SIB1. This allows a UE reselecting to a capacity cell when it moves from a coverage cell to a capacity cell. This allows the UE to receive traffic, providing better quality of service than if it were transmitting within the coverage cell.

[0069] At the same time, for this scenario, there are currently two types of network energy-saving methods: when the coverage cell determines that the data capacity demand in the cell is low, capacity cells A / B / C can be turned off to save network energy.

[0070] Cell selection and cell reselection:

[0071] In the cell selection and reselection process, cells can be divided into:

[0072] -Acceptable cell: According to the S criterion, it can meet the minimum access requirements;

[0073] - Suitable cell: According to the S criteria, it can provide normal services to the UE, and the Public Land Mobile Network (PLMN) to which the cell belongs is consistent with the UE's subscription data. Among them, the PLMN can uniquely identify a communication operator and is composed of a Mobile Country Code (MCC) and a Mobile Network Code (MNC);

[0074] - Reserved cell: The cell is indicated as reserved in the system information;

[0075] - Barred cell: The system information indicates that the cell is barred.

[0076] Cell selection criteria (S criteria):

[0077] During the cell selection process, the terminal needs to measure the channel of the cell to be selected in order to perform channel measurement, that is, to evaluate the channel quality and determine whether it meets the criteria for staying. The measurement criterion for cell selection is called the S criterion. When the channel quality and signal strength of a cell meet the S criterion, it may be selected as the cell to stay. Meeting the S criterion means that: Srxlev>0 AND Squal>0. Among them, the power criterion is: received power Srxlev>0, and the quality criterion is: the signal quality received during the cell search: Squal>0. Among them, Srxlev=Q rxlevmeas –(Q rxlevmin +Q rxlevminoffset )–P compensation -Qoffset temp

[0078] The parameters in the above formula are defined as follows:

[0079] Srxlev: Cell selection receiving level value.

[0080] Q rxlevmeas : The measured reception level value / signal strength of the cell (such as Reference Signal Received Power (RSRP)).

[0081] Q rxlevmin (Network-side configuration): Minimum cell receive level. Increasing this value for a cell makes it more difficult for it to meet the S criteria and become a suitable cell, making it more difficult for the UE to select it, and vice versa. This parameter should be set so that the selected cell can provide the signal quality requirements for basic services.

[0082] Q rxlevminoffset (Network-side configuration): Cell minimum receive level offset. This parameter is used only when the UE is camped on a VPLMN and cell selection is triggered by periodic searches for high-priority PLMNs. Increasing this value for a cell makes it more difficult for the cell to meet the S criterion and become a suitable cell, making it more difficult for the UE to select the cell, and vice versa.

[0083] P compensation (Network side configuration): Used to punish UEs that cannot reach the maximum power of the cell. When the UE's maximum allowed transmit power is less than or equal to the maximum transmit power supported by the UE's capabilities, P compensation = 0. When the maximum allowed transmit power of the UE is greater than the maximum transmit power supported by the UE capability, P compensation = UE maximum allowed transmit power - UE capability supported maximum transmit power.

[0084] Qoffset temp(Network side configuration): Temporary offset applied to this cell. This value is configured with the ConnEstFailOffset parameter in RRC and is used for connection failure control. Squal = Q qualmeas –(Q qualmin +Q qualminoffset )-Qoffset temp

[0085] The parameters in the above formula are defined as follows:

[0086] Squal: cell selection quality value;

[0087] Q qualmeas : Measured cell quality value (such as Reference Signal Received Quality (RSRQ));

[0088] Q qualmin (Network-side configuration): Minimum received signal quality. This parameter indicates the minimum received signal quality required for reselection and is used to control the difficulty of cell reselection. This parameter is issued in SIB5. Increasing this value for a cell makes it more difficult for the cell to meet the S criterion and become a suitable cell, making it more difficult for the UE to select the cell, and vice versa.

[0089] Q qualminoffset (Network-side configuration): Minimum received signal quality offset. This parameter indicates the minimum received signal quality offset for a cell and is applied to the cell selection criterion (S-criterion). This parameter is used only when the UE is residing in a VPLMN and cell selection is triggered by periodic searches for high-priority PLMNs. Increasing this value for a cell makes it more difficult for the cell to meet the S-criterion and become a suitable cell, making it more difficult for the UE to select the cell, and vice versa.

[0090] Qoffset temp (Network-side configuration): Temporary offset applied to this cell.

[0091] Cell reselection criteria (R criteria):

[0092] When a UE is idle / inactive, after cell selection, it continuously monitors the signal quality of neighboring cells and the current cell in order to camp on a cell with higher priority or better channel quality. If the signal quality and rating of a neighboring cell meet the S criterion and certain reselection criteria, the UE will camp on that cell.

[0093] Measurement criteria for cell reselection:

[0094] After the UE successfully camps on the cell, it will continue to measure the cell. To minimize the UE energy consumption caused by the measurement, the RRC layer calculates the S criterion based on the RSRP / RSRQ measurement results and compares it with the intra-frequency measurement start threshold (Sintrasearch) and the inter-frequency measurement start threshold (Snonintrasearch) as the decision condition for whether to start neighbor cell measurement.

[0095] The UE measures the serving cell signal and detects the serving cell signal strength Srxlev or quality Squal.

[0096] Intra-frequency measurement start criteria: Srxlev <= Sintrasearch or Squal <= Snonintrasearch.

[0097] Inter-frequency measurement starting criteria (for frequencies of the same or lower priority): Srxlev<=Snonintrasearch or Squal<=Sintrasearch.

[0098] During the reselection process, the network can control the UE's stay by setting the priority of different frequencies. The UE will select the cell with the best channel quality at a certain frequency to provide the best service. There are three ways for the UE to obtain the frequency priority information it needs to use:

[0099] (1) System information: For a certain frequency point, the corresponding absolute priority is provided in the system information;

[0100] (2) RRC Release message: If the frequency priority is provided by dedicated RRC signaling, the priority in the SI is ignored;

[0101] (3) Inherited from other radio access technologies (RAT).

[0102] Same-frequency and same-priority inter-frequency cell reselection criteria (R criteria):

[0103] The cell ranking criteria are defined as follows, where Rs is used for the serving cell and Rn is used for the neighboring cell.

[0104] Rs=Qmeas,s+Qhyst-Qoffsettemp

[0105] Rn=Qmeas,n-Qoffset–Qoffsettemp

[0106] Qmeas: RSRP measurement;

[0107] Qoffset: The offset between the target candidate cell and the current resident cell. It is used to adjust the difficulty of reselection and reduce the ping-pong effect. When other parameters remain constant, increasing the offset increases the difficulty of reselecting same-frequency or same-priority cells, and vice versa. For same-frequency reselection, this parameter is equal to the inter-cell Qoffsets,n (inter-cell Qoffsets,n exists in the system broadcast) or 0 (inter-cell Qoffsets,n does not exist in the system broadcast). For inter-frequency reselection, this parameter is equal to 'inter-frequency Qoffsetfrequency + inter-cell Qoffsets,n' (inter-cell Qoffsets,n exists in the system broadcast) or 'inter-frequency Qoffsetfrequency' (inter-cell Qoffsets,n does not exist in the system broadcast).

[0108] Qhyst: Hysteresis value of the serving cell measurement. This parameter is related to the slow fading characteristics of the cell environment. A larger slow fading variance indicates a larger hysteresis value. A larger hysteresis value also increases the serving cell boundary, making it more difficult to reselect to a neighboring cell. This value is used to adjust the reselection difficulty and reduce the ping-pong effect. An excessively large value can lead to delayed reselection. If the terminal initiates a connection at this time, RRC connection establishment may fail.

[0109] In the case of Hetnet scenarios where network energy saving is not performed, multiple Capacity Cells need to periodically send system information SIB1 even when there is no service, which results in increased ineffective energy consumption of the network.

[0110] The following, in conjunction with the accompanying drawings, describes in detail the system information processing method, apparatus, terminal, network-side equipment, etc. provided in the embodiments of the present application through some embodiments and their application scenarios.

[0111] Please refer to Figure 2, which is a flow chart of a system information processing method provided by an embodiment of the present application, wherein the method is applied to a terminal. As shown in Figure 2, the method includes the following steps:

[0112] Step 201: The terminal executes a first action.

[0113] The first behavior includes at least one of the following:

[0114] Sending an uplink request signal to a network-side device corresponding to the first cell, where the uplink request signal is used to request system information of the second cell group;

[0115] Downlink control information is received from a network side device corresponding to the first cell, where the downlink control information is used to notify the terminal to receive system information of the second cell group.

[0116] The second cell group includes at least one cell different from the first cell.

[0117] It should be noted that the terminal can perform the above-mentioned first behavior when it is stationed or connected to the first cell, that is, sending an uplink request signal to the network side device corresponding to the first cell and / or receiving downlink control information from the network side device corresponding to the first cell.

[0118] Optionally, the downlink control information is carried by at least one of the following:

[0119] paging channel;

[0120] Group common control channel.

[0121] Optionally, the downlink control information includes at least one of the following:

[0122] an indication of whether to send system information of the second cell group;

[0123] Scheduling information of the system information of the second cell group;

[0124] a period of system information of the second cell group;

[0125] An indication of at least one cell of the second group of cells.

[0126] For example, the downlink control information includes an indication of whether to send the system information of the second cell group, so that the terminal can determine whether the network side device corresponding to the first cell will send the system information of the second cell group. If the indication is not to send, the terminal can send an uplink request signal to the network side device corresponding to the first cell to request the system information of the second cell group.

[0127] Alternatively, the downlink control information includes scheduling information of the system information of the second cell group, and / or the period of the system information of the second cell group, and / or an indication of at least one cell of the second cell group, so that the terminal can clearly know how to receive the system information of the second cell group based on the downlink control information, such as receiving the system information of the second cell group periodically according to the period, thereby ensuring that the terminal receives the system information of the second cell group.

[0128] Optionally, the system information of the second cell group includes at least one of the following:

[0129] cell identification;

[0130] cell identification group;

[0131] system information of each cell in the second cell group;

[0132] Common system information of the second cell group.

[0133] Step 202: When the terminal resides in or is connected to a first cell, the terminal receives system information corresponding to at least one cell in a second cell group from a network-side device corresponding to the first cell.

[0134] Exemplarily, in a Hetnet scenario, the first cell may be a coverage cell, and the second cell group is a cell group composed of capacity cells, that is, the cells in the second cell group are capacity cells.

[0135] For example, in one embodiment, when the terminal resides in or is connected to a coverage cell, it sends an uplink request signal to the network-side device (such as a base station) corresponding to the coverage cell to request system information of the second cell group; further, after receiving the uplink request signal, the network-side device corresponding to the coverage cell sends system information corresponding to at least one cell (capacity cell) in the second cell group to the terminal, thereby enabling the terminal to obtain system information corresponding to at least one capacity cell. Furthermore, the network-side device corresponding to the coverage cell can send the system information corresponding to the capacity cell after receiving the uplink request signal from the terminal, thereby eliminating the need to periodically send system information, thereby avoiding the situation where the capacity cell needs to periodically send SIB1 even when there is no service, effectively saving energy consumption of network measurement equipment.

[0136] Alternatively, in another embodiment, when the terminal is resident on or connected to a coverage cell, it receives downlink control information from a network-side device corresponding to the coverage cell. The downlink control information is used to notify the terminal to receive system information of the second cell group, so that the terminal can obtain system information corresponding to at least one capacity cell. Furthermore, the network-side device corresponding to the coverage cell can pre-notify the terminal to receive the system information corresponding to the capacity cell without having to wait until the terminal switches to the capacity cell before sending it, thereby helping to reduce the service delay of the terminal and also helping to improve the service experience of the terminal.

[0137] It should be noted that the above is only an example of coverage cell and capacity cell. The first cell and the second cell group are not limited to the above situation, and the embodiment of the present application does not make specific limitations on this.

[0138] In an embodiment of the present application, when a terminal resides in or is connected to a first cell, it sends an uplink request signal to a network-side device corresponding to the first cell to request system information of a second cell group, or receives downlink control information from a network-side device corresponding to the first cell, wherein the downlink control information is used to notify the terminal to receive system information of the second cell group; further, the terminal receives system information corresponding to at least one cell in a second cell group from the network-side device corresponding to the first cell, wherein the second cell group includes at least one cell different from the first cell. Furthermore, the network-side device can send system information corresponding to at least one cell in the second cell group after receiving the uplink request signal sent by the terminal, thereby avoiding periodic transmission of system information and thus helping to save energy consumption of the network-side device; alternatively, the network-side device can notify the terminal to receive system information of the second cell group through downlink control information, thereby eliminating the need for the network-side device to periodically transmit system information, which also helps to reduce energy consumption of the network-side device.

[0139] Optionally, the uplink request signal is used to indicate at least one of the following:

[0140] A physical layer cell index or group index of the requested system information;

[0141] The serving cell index or group index of the requested system information;

[0142] The SSB frequency or group index of the requested system information;

[0143] Type information of the requested system information;

[0144] Partial information of the system information requested.

[0145] It can be understood that the uplink request signal indicates the above content, so that the network side device can know based on the uplink request signal which cell or cells in the second cell group the system information requested by the terminal corresponds to, which is more conducive to the accurate sending of system information.

[0146] Optionally, before the terminal sends the uplink request signal, the method further includes:

[0147] The terminal receives first configuration information, where the first configuration information includes at least one of the following:

[0148] Configuration information of the uplink request signal;

[0149] measurement configuration information of the at least one cell.

[0150] It should be noted that the terminal receives the first configuration information, such as the configuration information of the uplink request signal, from the network-side device corresponding to the first cell, so that the terminal can determine how to configure and send the uplink request signal based on the configuration information of the uplink request signal. Alternatively, the terminal receives measurement configuration information of at least one cell in the second cell group from the network-side device corresponding to the first cell, so that the terminal can determine how to configure and send the uplink request signal based on the measurement configuration information, such as requesting the system information of which cell in the second cell group. Furthermore, by sending the first configuration information, the network-side device helps the terminal to clarify the sending and configuration of the uplink request signal, thereby helping to improve the communication performance between the terminal and the network-side device.

[0151] Optionally, the configuration information of the uplink request signal satisfies at least one of the following:

[0152] The configuration information of the uplink request signal shares the physical random access channel PRACH configuration of the first cell for requesting OSI;

[0153] The configuration information of the uplink request signal shares the random access channel occasion (RO) configuration corresponding to the first cell;

[0154] The RO configuration corresponding to the configuration information of the uplink request signal is independent of the RO configuration corresponding to the first cell.

[0155] In some embodiments, the configuration information of the uplink request signal shares the PRACH configuration used by the first cell to request an OSI. For example, the terminal sends the PRACH configuration used to request an OSI to the network-side device corresponding to the first cell, and the network-side device corresponding to the first cell sends the OSI corresponding to the first cell and all system information in neighboring cells of the first cell that needs to be requested.

[0156] In some embodiments, the configuration information of the uplink request signal shares the RO configuration of the first cell, or is independent of the RO configuration of the first cell. For example, the configuration information of the uplink request signal is different from the RO configuration of the first cell.

[0157] Optionally, when the configuration information of the uplink request signal shares the RO configuration corresponding to the first cell, the configuration information of the uplink request signal configures at least one independent PRACH preamble code (Preamble) for corresponding to at least one cell in the neighboring area of ​​the first cell that needs to request to send system information.

[0158] For example, the uplink request signal includes a Preamble, which corresponds to all cells in the neighborhood of the first cell that need to request the transmission of system information. Alternatively, the uplink request signal includes multiple Preambles, each of which corresponds to a cell or a cell group consisting of multiple cells in the neighborhood of the first cell that need to request the transmission of system information. In this way, it is possible to configure one or more Preambles to correspond to the cell or cell group in the neighborhood of the first cell that needs to request the transmission of system information, so that the network side device corresponding to the first cell can also clarify which cells the terminal requests the transmission of system information based on the uplink request signal sent by the terminal.

[0159] Optionally, when the RO configuration corresponding to the configuration information of the uplink request signal is independent of the RO configuration corresponding to the first cell, the configuration information of the uplink request signal configures at least one independent RO for corresponding to at least one cell in the neighboring area of ​​the first cell that needs to request to send system information, and the at least one RO is mapped to the SSB, and one SSB after mapping corresponds to at least one RO.

[0160] For example, the uplink request signal includes multiple ROs, each of which corresponds to a cell or a cell group consisting of multiple cells in the neighborhood of the first cell for which system information is requested to be sent. Furthermore, by configuring at least one RO, the network-side device corresponding to the first cell can determine, based on the uplink request signal sent by the terminal, which cells the terminal is requesting to send system information for.

[0161] Optionally, when one SSB corresponds to at least one RO, the at least one RO and the preamble code of the RO correspond to a cell or a cell group consisting of multiple cells in the neighboring area of ​​the first cell that need to request to send system information.

[0162] In the embodiment of the present application, the first configuration information may further include measurement configuration information of the at least one cell in the second cell group, where the measurement configuration information is used to indicate at least one of the following:

[0163] Shared with the neighboring cell measurement configuration of the first cell, or an independent cell measurement configuration;

[0164] Adding at least one of the following items per frequency layer in the neighboring cell measurement configuration of the first cell: a list of neighboring cells that meet a first condition, indication information indicating whether all cells on the frequency layer meet the first condition, and an uplink request signal configuration corresponding to the cells on the frequency layer;

[0165] Adding at least one of the following items to each cell in the neighboring cell measurement configuration of the first cell: indication information indicating whether the cell meets the first condition and an uplink request signal configuration corresponding to the cell;

[0166] The first condition includes at least one of the following:

[0167] The system information can only be obtained by sending an uplink request signal;

[0168] No residency is allowed in the community;

[0169] The cell does not allow cell selection;

[0170] The cell does not allow cell reselection;

[0171] The cell allows uplink access;

[0172] The cell does not provide paging;

[0173] Only uplink traffic is allowed in the cell.

[0174] It should be noted that if a frequency layer in the neighboring cell measurement configuration of the first cell is not configured with the uplink request signal configuration corresponding to the cell on the frequency layer, it indicates that the cell on the frequency layer is a normal cell. Alternatively, if a cell in the neighboring cell measurement configuration of the first cell is not configured with the uplink request signal configuration corresponding to the cell, it indicates that the cell is a normal cell, and the normal cell can be understood as a cell that periodically sends SIB1.

[0175] In which case, when the measurement configuration information of the at least one cell is shared with the neighboring cell measurement configuration of the first cell, the terminal can determine whether the cell (that is, the cell corresponding to the measurement configuration information) meets the first condition through the content of the measurement signal.

[0176] Optionally, when the measurement configuration information is an independent cell measurement configuration, the measurement configuration information includes at least one of the following:

[0177] Measuring the frequency of configuration associations;

[0178] Measurement configuration associated cells;

[0179] The uplink request signal configuration corresponding to the cell associated with the measurement configuration;

[0180] Threshold parameters related to measurement result judgment, such as RSRP, RSRQ, etc.

[0181] Optionally, the cell associated with the measurement configuration meets the first condition.

[0182] Exemplarily, the cell associated with the measurement configuration satisfies the first condition, which may mean that the system information corresponding to the cell associated with the measurement configuration needs to send an uplink request signal to obtain, or the cell associated with the measurement configuration does not allow residency and / or does not allow cell selection and / or does not allow cell reselection and / or does not provide paging, etc. For another example, when the measurement configuration information is used to add indication information of whether all cells on the frequency layer meet the first condition in each frequency layer in the neighboring area measurement configuration of the first cell, the fact that all cells meet the first condition may mean that the system information corresponding to these cells needs to send an uplink request signal to obtain, or these cells allow uplink access or only allow uplink residency, or these cells do not allow residency and / or do not allow cell selection and / or do not allow cell reselection and / or do not provide paging, etc. Of course, the embodiments of the present application also include other cells that meet the first condition, such as cells in the neighboring area measurement configuration of the first cell, etc., which will not be described in detail here.

[0183] In the embodiment of the present application, by limiting the first condition, the cells that need to meet the first condition are limited, which helps to configure the terminal uplink request signal.

[0184] Optionally, the measurement start condition for the cell or frequency that meets the first condition includes at least one of the following:

[0185] The S criterion power standard of the serving cell or the camped cell is less than or equal to a preset first threshold value, where the first threshold value and the threshold value for initiating cell reselection may be the same or different;

[0186] The S criterion quality standard of the serving cell or the camped cell is less than or equal to a preset second threshold value, where the second threshold value and the threshold value for initiating cell reselection may be the same or different;

[0187] The power value (such as RSRP) measured in the serving cell or the resident cell is less than or equal to a preset third threshold value;

[0188] The quality value (eg, RSRQ) measured by the serving cell or the camped cell is less than or equal to a preset fourth threshold.

[0189] Optionally, the preset third threshold value includes the threshold value configured by the network side device for the cell or frequency that meets the first condition; or, the preset fourth threshold value includes the threshold value configured by the network side device for the cell or frequency that meets the first condition.

[0190] It should be noted that the relevant contents of the power standard (Srxlev) of the S criterion or the quality standard (Squal) of the S criterion are as described above and will not be repeated here.

[0191] In the embodiment of the present application, after the terminal sends the uplink request signal, the method may further include at least one of the following:

[0192] The terminal determines N candidate cells for uplink random access, where N is a positive integer;

[0193] The terminal determines M target cells for uplink random access or uplink camping, where M is a positive integer.

[0194] It can be understood that after the terminal sends an uplink request signal to the network-side device corresponding to the first cell, the terminal determines N candidate cells for uplink random access, so that the terminal can select a cell from the N candidate cells for uplink random access to ensure cell switching of the terminal. Alternatively, the terminal determines M target cells for uplink random access or uplink residence to ensure that the terminal can smoothly switch to one of the target cells, effectively reducing the terminal's switching delay.

[0195] Optionally, the candidate cell or the target cell meets a second condition, where the second condition includes at least one of the following:

[0196] a. meet the first condition;

[0197] b. The cell is a resident cell;

[0198] c. The cell measurement result meets the power standard of the S criterion, for example, Srxlev>0;

[0199] d. The cell measurement result meets the quality standard of the S criterion, for example, Squal>0;

[0200] e. The R criterion value of the cell is greater than the R criterion value of the resident cell or serving cell;

[0201] f. The difference between the RSRP measured by the cell and the RSRP of the resident cell or serving cell is greater than or equal to the first threshold, wherein the first threshold is greater than or equal to 0;

[0202] g. The difference between the RSRQ measured by the cell and the RSRQ of the camped cell or serving cell is greater than or equal to the second threshold, and the second threshold is greater than or equal to 0;

[0203] h. The R criterion value or RSRP or RSRQ measured by the cell is the first N or the first M of all measured cells, where N is the same value as the aforementioned N candidate cells, and M is the same value as the aforementioned M target cells;

[0204] i. The cell is a suitable cell;

[0205] j. The PLMN list of the cell contains the PLMNs registered by the terminal.

[0206] Optionally, the M target cells are cells randomly selected from the N candidate cells.

[0207] Optionally, when the M target cells are cells randomly selected from the N candidate cells, each of the N candidate cells corresponds to the same random selection probability; or, each of the N candidate cells corresponds to a different random selection probability.

[0208] For example, in one embodiment, each of the N candidate cells has the same probability of being selected as the target cell. Alternatively, in another embodiment, each of the N candidate cells includes a corresponding probability value of being selected as the target cell, and the terminal performs selection based on the probability value corresponding to each candidate cell, thereby determining M target cells. This makes the terminal more flexible in selecting target cells.

[0209] In an embodiment of the present application, the terminal can send an uplink request signal to the network side device corresponding to the first cell to request system information of the second cell group. The sending condition of the uplink request signal includes at least one of the following:

[0210] The first cell is a cell configured to meet the first condition;

[0211] The RSRP or RSRQ measured by the serving cell or the camped cell is less than or equal to a third threshold;

[0212] At least one cell that meets the first condition is a resident cell;

[0213] The measurement result of at least one cell that meets the first condition meets the power standard of the S criterion;

[0214] The measurement result of at least one cell that meets the first condition meets the quality standard of the S criterion;

[0215] The R criterion value of at least one cell that meets the first condition is greater than the R criterion value of the camped cell or the serving cell;

[0216] The difference between the RSRP of at least one cell that meets the first condition and the RSRP of the camped cell or the serving cell is greater than or equal to the first threshold;

[0217] At least one cell meeting the first condition is determined as a candidate cell for uplink random access or an uplink random access cell or a target cell for uplink camping;

[0218] The terminal has a need to send a random access signal to at least one cell that meets the first condition.

[0219] In the embodiment of the present application, the conditions for sending the uplink request signal are limited, thereby effectively regulating the terminal's sending behavior for the uplink request signal, which helps to improve the communication capability between the terminal and the network side device.

[0220] Optionally, after the terminal sends the uplink request signal, the method further includes:

[0221] The terminal sends a random access signal to a network-side device corresponding to a third cell, where the third cell satisfies any of the following conditions:

[0222] included in the second cell group;

[0223] is one of N candidate cells for uplink random access, the N candidate cells being the N candidate cells for uplink random access determined by the terminal;

[0224] It is one of the M target cells that can perform uplink random access or uplink camping, and the M target cells are also the M target cells that can perform uplink random access or uplink camping determined by the terminal.

[0225] For example, taking the Hetnet scenario as an example, the first cell is a coverage cell. The terminal is residing in or connected to the coverage cell. After the terminal sends an uplink request signal to the network side device corresponding to the first cell, it can send a random access signal to the network side device corresponding to the third cell (for example, a capacity cell) to request access to the third cell, thereby ensuring that the terminal can normally access the capacity cell to ensure the service quality of the terminal.

[0226] In order to better understand the technical solution of this application, several specific embodiments are explained below.

[0227] Example 1:

[0228] Step 11: The terminal sends an uplink request signal in the first cell to a network-side device corresponding to the first cell, where the uplink request signal is used to request system information of the second cell group;

[0229] Step 12: The terminal receives system information corresponding to at least one cell in a second cell group from a network-side device corresponding to the first cell; the second cell group includes one or more cells different from the first cell.

[0230] The configuration of the uplink request signal includes the following schemes:

[0231] In some embodiments, the uplink request signal fully shares the PRACH configuration used by the first cell to request OSI information. That is, the terminal transmits the PRACH in the first cell, and the base station corresponding to the first cell transmits the OSI corresponding to the first cell and all system information in the neighboring cells of the first cell (the second cell group) that needs to be requested. In this case, the uplink request signal is configured as a new SIB type or integrated into the existing OSI system information type. This way, the uplink request signal has no additional overhead, helping to save terminal energy consumption.

[0232] In some embodiments, the uplink request signal uses the RO configuration of the first cell to configure one or more independent PRACH preambles for system information request signals of one or more cells:

[0233] For example, the uplink request signal includes a Preamble corresponding to all cells in the neighboring cells of the first cell that need to request to send system information;

[0234] Alternatively, the uplink request signal includes multiple preambles, wherein each preamble corresponds to a cell group consisting of one cell or multiple cells in the neighboring cells of the first cell that need to request to send system information.

[0235] Optionally, when one SSB corresponds to multiple ROs, RO+Preamble corresponds to a cell group consisting of one or more cells in the neighboring cells of the first cell that need to request to send system information.

[0236] The advantage of this solution is that the terminal can request system information on demand, and the overhead of the network side device corresponding to the first cell sending the system information is small.

[0237] In some embodiments, the uplink request signal uses an RO configuration independent of the RO of the first cell, and configures one or more independent ROs for request signals of system information of one or more cells, wherein the one or more ROs are mapped to the SSB, and after mapping, one SSB corresponds to one or more ROs:

[0238] For example, the uplink request signal includes multiple preambles, where each preamble corresponds to a cell group consisting of one or more cells in the neighboring cells of the first cell that need to request to send system information;

[0239] Optionally, when one SSB corresponds to multiple ROs, RO+Preamble corresponds to a cell group consisting of one or more cells in the neighboring cells of the first cell that need to request to send system information.

[0240] The advantage of this solution is that the terminal can request system information on demand, and it is completely independent of the RACH for random access and does not affect the RACH capacity.

[0241] In addition, the conditions for sending the uplink request signal include the following schemes:

[0242] In some embodiments, the terminal receives system information of the first cell and determines that the system information of the first cell configures cells whose system information requires sending uplink request signals to obtain, then the terminal sends uplink request signals to obtain system information of all these cells.

[0243] In some embodiments, the terminal receives system information of the first cell and determines that the system information of the first cell configures a cell whose system information requires an uplink request signal to be acquired. Then, the terminal sends an uplink request signal based on the measurement result (refer to the second embodiment), including at least one of the following:

[0244] a) The RSRP or RSRQ measured in the serving / camped cell is lower than or equal to a certain threshold;

[0245] b) The measurement result of at least one cell that meets the first condition meets b / c / d / e / f of the above second conditions.

[0246] Optionally, the terminal sends an uplink request signal corresponding to the cell whose measurement result meets the conditions.

[0247] In some embodiments, the terminal receives system information of the first cell and determines that the system information of the first cell configures a cell that requires an uplink request signal to obtain system information. The terminal sends an uplink request signal based on the determined candidate cell or target cell for random access.

[0248] Optionally, the terminal sends an uplink request signal corresponding to the candidate cell or the target cell.

[0249] In this embodiment, the system information of the second cell group may be the following scheme:

[0250] In some embodiments, the second cell group system information includes a cell identifier and system information corresponding to the cell.

[0251] In some embodiments, the second cell group system information includes common system information and dedicated system information of each cell, that is, the common system information, the cell identifier, and the dedicated system information corresponding to the cell.

[0252] In some embodiments, the second cell group is divided into multiple subgroups, each subgroup corresponds to the same system information, namely, includes a cell group identifier and system information corresponding to the cell group, and the cells included in the cell group are configured.

[0253] In some embodiments, the second cell group is divided into multiple subgroups, each subgroup corresponds to public system information and dedicated system information of each cell in the group, that is, includes {cell group identifier, public system information corresponding to the cell group, cell identifier and dedicated system information corresponding to the cell}.

[0254] Example 2:

[0255] Step 21: The terminal receives a measurement configuration, where the measurement configuration is associated with at least one cell that meets a first condition.

[0256] Step 22: The terminal measures the serving / camped cell and at least one cell that meets the first condition.

[0257] The measurement configuration includes the following solutions:

[0258] In some embodiments, the measurement configuration completely reuses the current neighboring cell measurement configuration. At this time, the terminal determines whether it meets the first condition through the content of the neighboring cell measurement signal, for example, the SSB indicates whether the cell needs to trigger system information through an uplink request signal.

[0259] In some embodiments, at least one of the following is added per frequency layer in the neighboring cell measurement configuration of the first cell:

[0260] i. A list of neighboring cells that meet the first condition, where the first condition is as described above;

[0261] ii. Indicates whether all cells on the frequency layer meet the first condition;

[0262] iii. Configure the uplink request signal configuration corresponding to the frequency layer or cell; if this parameter is not configured, it means that all cells on the frequency layer are normal cells.

[0263] In some embodiments, at least one of the following is added to the neighboring cell measurement configuration of the first cell:

[0264] iv. an indication of whether the cell satisfies the first condition;

[0265] v. Configure the uplink request signal configuration corresponding to the cell; if this parameter is not configured, it means that the cell is a normal cell.

[0266] In some embodiments, an independent cell measurement configuration is added for a cell that meets the first condition, where the measurement configuration includes at least one of the following:

[0267] a) measuring the frequency of configuration association;

[0268] b) measuring the cell associated with the configuration;

[0269] c) measuring the uplink request signal configuration corresponding to the cell associated with the configuration;

[0270] d) The measurement results determine the relevant threshold parameters (RSRP, RSRQ).

[0271] Example 3:

[0272] The terminal determines at least one of the following based on the measurement result:

[0273] a) Determine N1 candidate cells (N1>=1) for uplink random access;

[0274] b) Determine N2 target cells for uplink random access or uplink camping (N2>=1).

[0275] In some embodiments, when the signal quality of the cell in which the terminal resides meets a certain condition, the terminal starts measuring and evaluating the cell that meets the first condition.

[0276] In some embodiments, the terminal evaluates cells that meet the first condition, and uses the cell with the largest R criterion value as a candidate cell or target cell for uplink random access.

[0277] In some embodiments, the terminal needs to perform tracking measurement on a candidate cell or target cell determined to be capable of uplink random access. Measurement evaluation of the cell meeting the first condition is initiated when at least one of the following conditions is met:

[0278] c) The signal quality of the resident cell meets certain conditions;

[0279] d) The signal quality of the candidate cell or target cell for uplink random access meets certain conditions.

[0280] Example 4:

[0281] Step 31: The terminal receives, in the first cell, a downlink control signal sent by a network-side device corresponding to the first cell, where the downlink control signal is used to notify the terminal of receiving system information of the second cell group.

[0282] Step 32: The terminal receives, in the first cell, system information corresponding to at least one cell in a second cell group sent by a network-side device corresponding to the first cell; the second cell group includes one or more cells different from the first cell.

[0283] In some embodiments, the downlink control information is transmitted via the paging channel (eg, paging message) of the base station and the group common channel, indicating that the terminal can receive the system information of the second cell group a certain time after the downlink control information is received.

[0284] In addition, it should be noted that when the terminal performs the following actions:

[0285] a terminal receives an uplink request signal configuration in the first cell, sends an uplink request signal in the first cell or the second cell, the uplink request signal requests the system information of the second cell;

[0286] b. The terminal receives system information on the second cell;

[0287] The behavior of the terminal in the above-mentioned embodiment 2 or embodiment 3 is applicable and will not be described in detail here.

[0307] The configuration information of the uplink request signal shares the RO configuration corresponding to the first cell;

[0308] The RO configuration corresponding to the configuration information of the uplink request signal is independent of the RO configuration corresponding to the first cell.

[0309] Optionally, when the configuration information of the uplink request signal shares the RO configuration corresponding to the first cell, the configuration information of the uplink request signal configures at least one independent PRACH preamble code for corresponding to at least one cell in the neighboring area of ​​the first cell that needs to request to send system information.
