[0101] FIG. 2 is an interaction diagram illustrating a method of receiving information according to an embodiment of the present disclosure.

[0102] In step S201, the network device transmits first information of a second cell to a terminal in a first cell.

[0103] In some embodiments, the terminal receives the first information of the second cell in the first cell.

[0104] In some embodiments, the first information of the second cell is in an on-demand transmission state.

[0105] In some embodiments, the first information comprises at least one of: system information, a Synchronization Signal Block (SSB).

[0106] In some embodiments, the SSB can contain a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS), a Physical Broadcast Channel (PBCH), etc.

[0107] In some embodiments, the system information can comprise a System Information Block (SIB), wherein the SIB can comprise, for example, a SIB1, and can also comprise other SIBs.

[0108] The following embodiments mainly take the case where the first information comprises system information as an example to illustrate the technical solutions of the present disclosure, and any embodiment applicable to system information is also applicable to the case where the first information comprises an SSB.

[0109] In step S202, the terminal determines that the random access to the second cell can be initiated in the case where it is determined that the first condition is met (for example, the communication environment meets the first condition).

[0110] In some embodiments, the network device can suspend the transmission of system information in the second cell for some reason, for example, adjust the system information of the second cell from a traditional transmission state to an on-demand transmission state.

[0111] In some embodiments, the network device can stop transmitting system information in the second cell for some reason, for example, transmit the system information of the second cell based on the first cell.

[0112] In some embodiments, the system information of the second cell is in a traditional transmission state, which can mean that the network device transmits the system information in the second cell based on a configuration or a protocol predefined rule.

[0113] In some embodiments, the system information of the second cell is in an on-demand transmission state, which can mean that the network device stops transmitting the system information in the second cell based on a configuration or a protocol predefined rule, and waits until the system information needs to be transmitted (for example, based on the implementation of the network device, or based on the terminal request), and then transmits based on the configuration or the protocol predefined rule.

[0114] For example, the system information in the second cell is in the on-demand transmission state, the network device can decide whether to transmit the system information in the second cell based on implementation.

[0115] For example, the system information in the second cell is in the on-demand transmission state, the terminal can transmit request information to the network device in the case of needing to acquire the system information in the second cell, the request information is used to request the network device to transmit the system information in the second cell. In this case, the network device can decide whether to transmit the system information in the second cell based on implementation.

[0116] For example, the request information can also be called a wake-up signal (WUS) when the network device and / or the second cell is in the dormant state.

[0117] In some embodiments, considering that the system information in the second cell is in the on-demand transmission state, the reason can be that the second cell supports NES and is in the dormant state. In this case, if the network device is requested to transmit the system information in the second cell, it will cause the second cell to leave the dormant state, and the second cell being in the dormant state is conducive to reducing network transmission power consumption, and the second cell leaving the dormant state is not conducive to reducing network transmission power consumption, thereby not meeting the power consumption reduction requirement of the second cell.

[0118] Therefore, in some embodiments, the system information can be transmitted by the first cell other than the second cell (i.e., the network device transmits in the first cell), without the second cell transmitting (i.e., the network device does not transmit in the second cell), which is conducive to ensuring that the second cell does not leave the dormant state, and the second cell being in the dormant state is conducive to reducing network transmission power consumption, so as to meet the power consumption reduction requirement of the second cell.

[0119] And the relevant information contained in the system information of the second cell can be used by the terminal in the process of initiating random access to the second cell, so that the terminal can also acquire the system information of the second cell from the first cell in the case of failing to acquire the system information from the second cell, thereby successfully initiating random access to the second cell.

[0120] It should be noted that in some embodiments, since the second cell is in the dormant state, the terminal can camp on the first cell and initiate random access to the second cell based on demand under certain conditions and complete communication in the second cell, and in this process, the terminal still camps on the first cell, which is conducive to the second cell returning to the dormant state as soon as possible and stopping data transmission with the terminal, so as to meet the power consumption reduction requirement of the second cell.

[0121] FIG. 3 is a schematic flowchart illustrating a system information sending method according to an embodiment of the present disclosure.

[0122] As shown in FIG. 3, the second cell is a cell supporting NES, and the second cell can be in a dormant state. When the second cell is in the dormant state, the network device suspends sending system information in the second cell, for example, the system information in the second cell is in an on-demand transmission state.

[0123] The first cell can provide the terminal with a WUS configuration, and the terminal can send a WUS to the first cell according to the WUS configuration when it needs to acquire the configuration information of the second cell. After receiving the WUS, the first cell can send the system information of the second cell to the terminal, so that the terminal can receive the system information of the second cell in the first cell. For example, the WUS configuration can be based on the system information of the second cell, or RRC, MAC CE or DCI, which is not limited by the present disclosure.

[0124] For example, the system information of the second cell can be acquired by the first cell (for example, the network device of the first cell) from the second cell (for example, the network device corresponding to the second cell), or can be acquired from the core network device, which is not limited by the present disclosure.

[0125] It should be noted that the system information of the second cell can be sent by the network device in the first cell after the first cell receives the WUS from the terminal, or the network device can decide whether to send the system information of the second cell in the first cell based on implementation; and the system information of the first cell itself can be in a traditional sending state and be sent based on a periodic or protocol predefined rule.

[0126] In the related art, the terminal initiates random access to the second cell, and needs to camp on the second cell to receive the system information of the second cell. In this case, the terminal can relatively accurately determine that the second cell meets the coverage needs and network requirements, and then initiates random access to the second cell.

[0127] In the scenario of the embodiment shown in FIG. 3, the terminal camps on the first cell and receives the system information of the second cell in the first cell. In this case, the terminal cannot camp on the second cell and cannot meet the condition of random access in the prior art, and the terminal can not accurately determine the coverage of the second cell, which can cause the second cell not to meet the coverage needs, and then cause the terminal to fail to initiate random access to the second cell, resulting in waste of the terminal's overhead.

[0128] According to the embodiments of the present disclosure, in the case that the system information is in the on-demand state in the second cell, the terminal can determine that the random access to the second cell can be initiated only in the case that the first condition is met, instead of determining that the random access to the second cell can be initiated in the case that the first condition is not met, which is beneficial to avoid the failure of the random access to the second cell initiated by the terminal and the waste of the overhead of the terminal.

[0129] In some embodiments, in the case that the terminal determines that the random access to the second cell can be initiated, the terminal can determine whether to initiate the random access to the second cell according to the needs of the terminal itself and / or the access requirements of the operator.

[0130] For example, the access requirements of the operator can be represented by a Public Land Mobile Network (PLMN) related configuration, which can be predefined or indicated by the network device, for example, the network device indicates the PLMN related configuration through the SIB1.

[0131] The PLMN related configuration can indicate whether the terminal can camp on or access the second cell. When the terminal determines that the terminal cannot camp on or access the second cell based on the PLMN related configuration, it can be determined that the random access to the second cell cannot be initiated, so that the random access to the second cell will not be initiated. When the terminal determines that the terminal can camp on or access the second cell based on the PLMN related configuration, it can be determined that the random access to the second cell can be initiated, so that the random access to the second cell can be initiated according to the needs.

[0132] For example, the terminal determines that the communication of the second cell needs to be accessed based on the needs of the terminal itself, and then determines that the random access to the second cell can be initiated in the case that the random access to the second cell can be initiated. If the terminal determines that the communication of the second cell does not need to be accessed, the random access to the second cell can not be initiated even if the random access to the second cell can be initiated.

[0133] In some embodiments, the configuration information for initiating the random access to the second cell is included in the system information of the first cell.

[0134] For example, the configuration information for initiating the random access to the second cell can include random access channel (RACH) configuration information, and the system information of the first cell can carry the RACH configuration information and send it to the terminal.

[0135] However, the configuration information for initiating random access to the second cell in the embodiments of the present disclosure is not limited to being carried by the system information of the first cell, for example, can be carried by the WUS configuration information sent by the first cell to the terminal, or can also be carried by other information, for example, RRC, MAC CE or DCI, and the present disclosure does not limit this.

[0136] In some embodiments, the terminal sends (for example, sends to the network device in the first cell) a wake-up signal (WUS) in the first cell, wherein the wake-up signal is used to request the network device to send the system information of the second cell in the first cell.

[0137] In some embodiments, the configuration information of the wake-up signal is used to indicate whether the second cell is a cell supporting network energy saving or is in a network energy saving state. In some embodiments, the second cell is a cell supporting network energy saving.

[0138] For example, the second cell can be a NES supporting cell, and the second cell can be in a sleep state or can not be in a sleep state. Whether the second cell is in a sleep state can be indicated to the terminal by the network device through the configuration information of the WUS. For example, the terminal can receive the configuration information of the WUS in the first cell. It can also be implemented based on the needs of the network device.

[0139] For example, the related information of the second cell (for example, whether it is in a sleep state) can be determined based on a predefined manner (for example, protocol agreement) or based on network device indication. For example, the terminal determines that the configuration can be applied to the second cell according to the WUS configuration sent by the network device, and then determines that the second cell is in a sleep state and / or the second cell is a NES supporting cell.

[0140] In some embodiments, the first condition includes at least one of the following:

[0141] The first cell and the second cell are inter-frequency cells;

[0142] The first cell and the second cell are intra-frequency cells;

[0143] The priority of the second cell is higher than the priority of the first cell;

[0144] The priority of the second cell is lower than the priority of the first cell;

[0145] The priority of the first cell is equal to the priority of the second cell;

[0146] The first parameter of the second cell is greater than a first threshold value;

[0147] the first parameter of the first cell is less than a second threshold value;

[0148] the second parameter of the second cell belongs to a first value range;

[0149] the second parameter of the second cell is greater than the second parameter of the first cell.

[0150] In some embodiments, the first cell and the second cell are inter-frequency cells, which can mean that the frequency point corresponding to the first cell is different from the frequency point corresponding to the second cell, or the frequency domain range corresponding to the first cell is different from the frequency domain range corresponding to the second cell. The frequency point may, for example, be represented by an absolute radio frequency channel number (ARFCN).

[0151] In some embodiments, the first parameter and / or the second parameter are determined based on measurement of a reference signal. In some embodiments, the resource information of the reference signal is included in the system information of the first cell, and / or the resource information of the reference signal is included in the system information of the second cell.

[0152] For example, the reference signal includes but is not limited to SSB and channel state information reference signal (CSI-RS).

[0153] For example, the terminal can measure the reference signal in the second cell and / or the reference signal in the neighboring cell of the second cell according to the resource information of the reference signal to obtain the first parameter and / or the second parameter.

[0154] The resource information of the reference signal may, for example, be included in the system information of the first cell or the system information of the second cell.

[0155] It should be noted that the resource information of the reference signal is not limited to being carried in the system information of the first cell or the system information of the second cell, but can also be carried in other information. For example, the resource information of the reference signal can be carried in radio resource control (RRC) signaling, downlink control information (DCI), media access control control element (MAC CE), or the resource information of the reference signal can be predefined (for example, agreed by a protocol), and the disclosure does not limit this.

[0156] In some embodiments, the first condition comprises: the first cell and the second cell are inter-frequency cells, and / or, the priority of the second cell is higher than the priority of the first cell; and the first parameter of the second cell is greater than the first threshold. The priority in this embodiment may, for example, be referred to as a cell reselection priority.

[0157] For example, in the scenario where the first cell and the second cell are inter-frequency cells, the first condition may, for example, comprise that the first parameter of the second cell is greater than the first threshold.

[0158] For example, the first condition may, for example, comprise that the priority of the second cell is higher than the priority of the first cell, and the first parameter of the second cell is greater than the first threshold.

[0159] For example, in the scenario where the first cell and the second cell are inter-frequency cells, the first condition may, for example, comprise that the priority of the second cell is higher than the priority of the first cell, and the first parameter of the second cell is greater than the first threshold.

[0160] In this embodiment, when the first cell and the second cell are inter-frequency cells, and / or, the priority of the second cell is higher than the priority of the first cell, the terminal is camped in the first cell, and the second cell has a relatively high probability of meeting the coverage requirement, so for the second cell, it is only necessary to determine whether the first parameter of the second cell is greater than the first threshold.

[0161] For example, the first threshold may, for example, be represented as Thresh X,HighQ The first threshold may, for example, be configured based on system information of the first cell, or the first threshold may, for example, be configured based on system information of the second cell, and the present disclosure is not limited thereto.

[0162] For example, in the case where the first parameter of the second cell is greater than the first threshold, it may, for example, be determined that the second cell does meet the coverage requirement, and reselecting to the second cell is conducive to achieving higher communication quality, so it may, for example, be determined that the second cell can be initiated for on-demand access.

[0163] In some embodiments, the state in which the first parameter of the second cell is greater than the first threshold lasts for a duration greater than or equal to a first duration.

[0164] For example, in the first condition, the first parameter of the second cell being greater than the first threshold may, for example, be that the first parameter of the second cell is greater than the first threshold for a relatively long duration, for example, for a duration greater than or equal to a first duration.

[0165] On this basis, it may, for example, be determined that the first parameter does meet the first condition only in the case where the first parameter of the second cell is greater than the first threshold for a relatively long duration, so as to avoid misjudging that the first condition is met when the first parameter of the second cell is greater than the first threshold only for a short time.

[0166] The first time length may be represented as Treselection, for example. RAT The first time length may be indicated by the network device or predefined (e.g. agreed by protocol), which is not limited in the disclosure.

[0167] In some embodiments, the first parameter is determined based on at least one of the following:

[0168] a parameter related to the measured first cell quality value;

[0169] a parameter related to the measured first cell reception level value;

[0170] a parameter indicated by the network device or predefined.

[0171] For example, the first parameter may include at least one of S qual and S rxlev .

[0172] For example, the first parameter includes S qual , S qual may be determined based on at least one of Q qualmeas , Q qualmin , Q qualminoffset , Q offsettemp . For example, S qual = Q qualmeas -(Q qualmin +Q qualminoffset )-Q offsettemp .

[0173] For example, Q qualmeas is used to represent the measured first cell quality value, and the Q qualmin , Q qualminoffset , Q offsettemp are values indicated by the network device or predefined values.

[0174] The definition of the parameters in the above embodiments can refer to Table 1 below:

[0175] Table 1

[0176] wherein RSRP refers to Reference Signal Receiving Power, RSSI refers to Received Signal Strength Indication, RSRQ refers to Reference Signal Receiving Quality, ConnEstFailureControl refers to Connection Establishment Failure Control, and connEstFailOffset refers to Connection Establishment Failure Offset.

[0177] Q qualmin Q qualminoffset Q offsettemp may be determined based on a predefinition or a network device indication.

[0178] For example, in the case of Q qualmin Q qualminoffset Q offsettemp In the case of being indicated by a network device, for example, the network device can indicate Q qualmin , for example, the network device can indicate Q qualminoffset , for example, the network device can indicate Q offsettemp For example, the related meanings of q-QualMIn and q-QualMInOffset can refer to TS 36.304 [4] in 3GPP communication protocol.

[0179] In some embodiments, the first condition comprises: the first cell and the second cell are inter-frequency cells, and / or the priority of the second cell is lower than the priority of the first cell; and the first parameter of the second cell is greater than the second threshold, and the first parameter of the first cell is less than the second threshold. The priority in the embodiment can be referred to as cell reselection priority.

[0180] For example, in the case of the first cell and the second cell being inter-frequency cells, the first condition can comprise the first parameter of the second cell being greater than the second threshold, and the first parameter of the first cell being less than the second threshold.

[0181] For example, the first condition can comprise the priority of the second cell being lower than the priority of the first cell, the first parameter of the second cell being greater than the second threshold, and the first parameter of the first cell being less than the second threshold.

[0182] For example, in the scenario that the first cell and the second cell are inter-frequency cells, the first condition can comprise that the priority of the second cell is lower than the priority of the first cell, the first parameter of the second cell is greater than the second threshold, and the first parameter of the first cell is less than the second threshold.

[0183] In the embodiment, when the first cell and the second cell are inter-frequency cells, and / or the priority of the second cell is lower than the priority of the first cell, the terminal camps in the first cell for cell reselection, and the second cell only has a relatively low probability of meeting the coverage requirement, therefore, for the second cell, it is not only necessary to determine whether the first parameter of the second cell is greater than the first threshold, but also necessary to determine whether the first parameter of the first cell is less than the second threshold.

[0184] For example, the second threshold can be represented as Thresh X,LowP The second threshold can be configured based on system information of the first cell, or the second threshold can be configured based on system information of the second cell, and the disclosure does not limit this.

[0185] For example, in the case that the first parameter of the second cell is greater than the second threshold, and the first parameter of the first cell is less than the second threshold, it can be determined that the second cell has a greater probability of meeting the coverage requirement relative to the first cell, and reselecting to the second cell is conducive to achieving higher communication quality, so it can be determined that the second cell can be initiated for random access.

[0186] In some embodiments, the first parameter of the second cell is greater than the second threshold, and / or the state duration that the first parameter of the first cell is less than the second threshold is greater than or equal to the second duration.

[0187] For example, the first parameter of the second cell is greater than the second threshold, and / or the first parameter of the first cell is less than the second threshold, specifically, the first parameter of the second cell is greater than the second threshold, and / or the first parameter of the first cell is less than the second threshold for a relatively long time, for example, the state duration is greater than or equal to the second duration.

[0188] On this basis, only in the case that the first parameter of the second cell is greater than the second threshold, and / or the first parameter of the first cell is less than the second threshold for a relatively long time, it can be determined that the first parameter indeed meets the first condition, so as to avoid that the first parameter of the second cell is only greater than the second threshold for a short time, and / or the first parameter of the first cell is only less than the second threshold for a short time, and misjudge that the first condition is met.

[0189] Wherein, the second duration can be represented as Treselection RATThe second time length can be indicated by the network device or predefined (for example, agreed by protocol), and the disclosure does not limit this.

[0190] For example, the first parameter can include S qual and at least one of S rxlev .

[0191] For example, the first parameter includes S rxlev , S rxlev may be determined based on at least one of Q rxlevmeas , Q rxlevmin , Q rxlevminoffset , P compensation , Q offsettemp . For example, S rxlev = Q rxlevmeas -(Q rxlevmin +Q rxlevminoffset )-P compensation -Q offsettemp .

[0192] For example, the Q rxlevmeas is used to represent the measured first cell received level value, and the Q offsettemp , Q rxlevmin , Q rxlevminoffset , P compensation are values indicated by the network device or predefined values.

[0193] The definition of the parameters in the above embodiments can refer to Table 2 below:

[0194] Table 2

[0195] Wherein, RSRP refers to Reference Signal Receiving Power, ConnEstFailureControl refers to connection establishment failure control, and connEstFailOffset refers to connection establishment failure offset.

[0196] Q qualmin , Q qualminoffset , Q offsettemp may be determined based on predefinition or network device indication.

[0197] For example, in the case where Q rxlevmeas , Q rxlevminoffset , Q offsettemp are indicated by the network device, for example, the network device can indicate Q rxlevmeasFor example, the network device can indicate Q rxlevminoffset For example, the network device can indicate Q offsettemp For example, the related meanings of Q-RxLevMin, q-RxLevMinOffset can refer to TS 36.304 [4] in 3GPP communication protocol.

[0198] In some embodiments, the first condition comprises: the first cell and the second cell are intra-frequency cells, and / or the priority of the first cell is equal to the priority of the second cell; and the second parameter of the second cell belongs to a first value range, and / or the second parameter (e.g. R value) of the second cell is greater than the second parameter (e.g. R value) of the first cell.

[0199] For example, in the scenario that the first cell and the second cell are intra-frequency cells, the first condition comprises that the second parameter of the second cell belongs to a first value range.

[0200] For example, the priority of the first cell is equal to the priority of the second cell, and the second parameter of the second cell belongs to a first value range.

[0201] For example, in the scenario that the first cell and the second cell are intra-frequency cells, the first condition comprises that the second parameter of the second cell is greater than the second parameter of the first cell.

[0202] For example, the priority of the first cell is equal to the priority of the second cell, and the second parameter of the second cell is greater than the second parameter of the first cell.

[0203] For example, in the scenario that the first cell and the second cell are intra-frequency cells, the first condition comprises that the priority of the first cell is equal to the priority of the second cell, and the second parameter of the second cell belongs to a first value range.

[0204] For example, in the scenario that the first cell and the second cell are intra-frequency cells, the first condition comprises that the priority of the first cell is equal to the priority of the second cell, and the second parameter of the second cell is greater than the second parameter of the first cell.

[0205] For example, in the scenario that the first cell and the second cell are intra-frequency cells, the first condition comprises that the second parameter of the second cell belongs to a first value range, and the second parameter of the second cell is greater than the second parameter of the first cell.

[0206] For example, the priority of the first cell is equal to the priority of the second cell, the second parameter of the second cell is greater than the second parameter of the first cell, and the second parameter of the second cell is greater than the second parameter of the first cell.

[0207] For example, in a scenario where the first cell and the second cell are intra-frequency cells, the first condition includes that the priority of the first cell is equal to the priority of the second cell, the second parameter of the second cell belongs to a first value range, and the second parameter of the second cell is greater than the second parameter of the first cell.

[0208] In this embodiment, when the first cell and the second cell are intra-frequency cells, or when the priorities of the first cell and the second cell are equal, cell reselection can be performed according to the case of intra-frequency cells. On this basis, in order to determine whether the second cell can be reselected, it can be determined whether the second parameter of the second cell belongs to the first value range, or whether the second parameter of the second cell is greater than the second parameter of the first cell.

[0209] For example, the first value range can be [R best-rangeToBestCell ,R best ], where R best is the R value corresponding to the cell with the highest ranking of the second parameter (the R value is the largest), and the R value may, for example, include at least one of R s , R n . If multiple cells meet the above requirements, the terminal selects the cell with the highest ranking of the R value. R best-rangeToBestCell is a value indicated by the network device or a predefined (for example, agreed by the protocol) value, and the present disclosure does not limit this.

[0210] When the second parameter of the second cell belongs to the first value range, and / or the second parameter of the second cell is greater than the second parameter of the first cell, it can be determined that the second cell indeed meets the coverage requirement, and reselecting to the second cell is beneficial to achieve higher communication quality, so it can be determined that the on-demand access to the second cell can be initiated.

[0211] In some embodiments, the second parameter of the second cell belongs to the first value range, and / or the state duration that the second parameter of the second cell is greater than the second parameter of the first cell is greater than or equal to a third duration.

[0212] For example, the second parameter of the second cell belongs to the first value range, and / or, the state duration that the second parameter of the second cell is greater than the second parameter of the first cell is greater than or equal to the third duration, specifically, the second parameter of the second cell belongs to the first value range, and / or, the state duration that the second parameter of the second cell is greater than the second parameter of the first cell is greater than or equal to the third duration is relatively long, for example, the duration is greater than or equal to the third duration.

[0213] On this basis, in the case that the second parameter of the second cell belongs to the first value range, and / or, the state duration that the second parameter of the second cell is greater than the second parameter of the first cell is relatively long, it is determined that the first parameter really satisfies the first condition, so as to avoid that the second parameter of the second cell only belongs to the first value range for a short time, and / or, the second parameter is only greater than the second parameter of the first cell for a short time, and the first condition is misjudged as being satisfied.

[0214] The third duration may, for example, represent Treselection RAT The second duration may be indicated by the network device or may be predefined (for example, agreed by a protocol), and the disclosure does not limit this.

[0215] In some embodiments, the terminal may compare S qual and S rxlev When S rxlev > S IntraSearchP and / or S qual > S IntraSearchQ , the terminal may not perform intra-frequency measurement, otherwise, the terminal performs intra-frequency measurement. The threshold values S IntraSearchP and S IntraSearchQ may be values indicated by the network device (for example, indicated by SIB2) or predefined values (for example, agreed by a protocol), and the disclosure does not limit this.

[0216] For example, in the case of determining to perform intra-frequency measurement, the first condition includes: the first cell and the second cell are same-frequency cells, and / or, the priority of the first cell is equal to the priority of the second cell; and the second parameter of the second cell belongs to the first value range, and / or, the second parameter of the second cell is greater than the second parameter of the first cell.

[0217] In some embodiments, the second parameter is determined based on at least one of the following:

[0218] a reference signal received power measurement quality related parameter of the first cell;

[0219] Parameters related to the quality of the reference signal received power measurement in neighboring cells;

[0220] Parameters indicated or predefined by the network device.

[0221] For example, the second parameter may include R s and R n At least one of them.

[0222] For example, R s Can be based on Q meas,s Q hyst Q offsettemp At least one parameter is determined. For example, R s =Q meas,s +Q hyst -Q offsettemp .
