WO2025166770A1 - State determination and inidication methods and apparatus, communication system, and storage medium - Google Patents

Abstract

The present disclosure relates to the technical field of communications, and relates in particular to state determination and indication methods and apparatus, a communication system, and a storage medium. The state determination method comprises: in response to first information of a first cell being unobtainable, determining the state of the first cell, the state of the first cell comprising: the first cell being in a prohibited state or the first cell being in a non-prohibited state. The present disclosure avoids a first cell being determined to be in a prohibited state when first information is in an on-demand state, rather than when the signal quality of the first cell is too poor for a terminal, leading the terminal to rarely reside in the first cell, thereby creating wireless resource waste in a network.

Description

State determination, indication method and device, communication system and storage medium Technical Field

The present disclosure relates to the field of communication technology, and in particular to a state determination method, a state indication method, a state determination device, a state indication device, a terminal, a network device, a communication system, and a storage medium.

The method includes: in response to an inability to obtain first information of a first cell, determining the status of the first cell, wherein the status of the first cell includes: the first cell is in a prohibited state; or the first cell is in a non-prohibited state.

According to a second aspect of an embodiment of the present disclosure, a status indication method is proposed, which is executed by a network device. The method includes: sending first indication information to a terminal, wherein the first indication information is used to determine the status of the first cell in response to the terminal being unable to obtain first information of the first cell, wherein the status of the first cell includes: the first cell is in a prohibited state; or the first cell is in a non-prohibited state.

In some embodiments, the main purpose of cell selection is to enable the terminal to quickly select a cell with satisfactory signal quality under the selected PLMN (Public Land Mobile Network) for residency. The terminal determines whether the cell selection conditions are met based on the measured cell signal strength (e.g., Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ)) and related parameters, which can be configured based on the System Information Block (SIB)1.

The terminal is in disconnected state:

The terminal has camped on a cell (for example, completed the cell selection process).

A UE that meets the above conditions can select a more suitable cell by continuously performing cell quality detection and/or measurement.

In some embodiments, when performing cell selection or cell reselection among candidate cells, the terminal may receive first information from the candidate cells, such as System Information Block (SIB) 1. When the terminal fails to receive the first information from the first cell among the candidate cells, the terminal determines that the first cell is in a barred state, i.e., the first cell is excluded from candidate cells for a period of time (e.g., 300 seconds). During this period, the terminal will not consider the first cell as a candidate cell when performing cell selection or cell reselection, and will not select or reselect the first cell.

However, there are many reasons why the terminal cannot receive the first information in the first cell. For example, the signal quality of the first cell is too poor for the terminal. Although the network device sends the first information in the first cell, the terminal cannot receive the first information. For example, when the network device is about to enter the Network Energy Saving (NSE) mode or is already in the NES mode, the first information may be in an on-demand state in the first cell. That is, the network device stops sending the first information in the first cell. When the terminal needs to obtain the first information, it may send a request message to the network device. After receiving the request message, the network device may choose to send the first information in the first cell.

It can be seen that the terminal cannot receive the first information in the first cell, which may not be caused by the poor signal quality of the first cell for the terminal. It may be that the first information is in an on-demand state in the first cell, not because the signal quality of the first cell is poor for the terminal.

In this case, if the terminal cannot receive the first information in the first cell, it is inaccurate to directly determine that the first cell is in a banned state. For example, for a specific first cell, it is possible that the signal quality of the first cell is acceptable for the terminal, but the first information in the first cell is in an on-demand state, causing the terminal to determine the first cell as a banned state and no longer attempt to reside in the first cell, resulting in very few terminals residing in the first cell, wasting wireless resources in the network.

FIG2 is an interactive schematic diagram illustrating a state determination method according to an embodiment of the present disclosure.

As shown in FIG2 , the state determination method may include the following steps:

In step S201, the terminal attempts to obtain first information of a first cell.

In some embodiments, the terminal may attempt to obtain the first information of the first cell based on the first condition. That is, if the first condition is met, the terminal may attempt to obtain the first information of the first cell.

In some embodiments, the first condition may include at least one of the following:

The terminal is in a non-connected state, wherein the non-connected state includes at least one of the following: an idle state and an inactive state;

The terminal obtains indication information for indicating that the first information is transmitted in the first cell. For example, the indication information may include an information element (IE) ssb-SubcarrierOffset (which may be translated as synchronized broadcast signal block subcarrier offset).

The terminal sends a request message to the network device, wherein the request message is used to request the network device to send the first information;

The terminal is in a connected state and receives a system information change indication;

The terminal is in a connected state, and the T311 timer (the specific meaning can be referred to in the relevant art, and the present disclosure does not elaborate on its meaning here) is running;

The terminal is in a connected state and fails to obtain a valid version of system information, or fails to obtain valid system information (eg, SIB1) during a current modification.

For example, in some embodiments, when the terminal is in a non-connected state, the terminal may attempt to acquire first information of the first cell.

In some embodiments, when the terminal obtains indication information for indicating that the first information is transmitted in the first cell, the terminal may attempt to obtain the first information of the first cell.

In some embodiments, when the terminal sends request information to the network device to request the network device to send first information to the terminal, the terminal may attempt to obtain the first information of the first cell.

In some embodiments, when the terminal is in a connected state and receives a system information change indication, the terminal may attempt to obtain first information of the first cell.

In some embodiments, when the terminal is in a connected state and the T311 timer is running, the terminal may attempt to obtain the first information of the first cell. The activation and operation mechanism of the T311 timer has been described in detail in the relevant art and will not be repeated here.

In some embodiments, when the terminal is in a connected state and the terminal fails to obtain a valid version of system information, or does not obtain valid system information during the current modification, the terminal may try to Try to obtain the first information of the first cell.

In step S201, the terminal attempts to obtain first information of a first cell. In some embodiments, the terminal successfully obtains the first information of the first cell, while in some embodiments, the terminal cannot obtain the first information of the first cell.

In step S202, in response to the terminal being unable to obtain the first information of the first cell, the terminal determines a state of the first cell, where the state of the first cell includes:

The first cell is in a barred state; or

The first cell is in a not barred state.

The terminal attempts to obtain first information of the first cell and determines the state of the first cell according to the obtained result. In some embodiments, the terminal determines that the first information of the first cell is obtained, and thus can perform cell selection/reselection or camp on the first cell based on the first information.

In some embodiments, the terminal determines that the first information cannot be obtained, which can be determined based on terminal implementation or based on a predefined method. In short, the terminal determines that the acquisition of the first information is unsuccessful.

For example, the terminal determines that it cannot obtain the first information based on its own implementation, which may include the terminal attempting to obtain the first information based on the first condition, and attempting to obtain the first information one or more times in the transmission cycle of the first information, but failing to successfully obtain the first information, and the terminal determines that it cannot obtain the first information in the first cell.

For example, the terminal determines that it cannot obtain the first information based on a predefined method. The predefined rules may include the terminal attempting to obtain the first information based on the first condition, and attempting to obtain the first information in n times (n is an integer greater than or equal to 1, which can be agreed upon by the protocol or indicated by the network or determined based on the terminal capability) the transmission period of the first information, and the terminal determines that the first information cannot be obtained in the first cell.

In some embodiments, if the terminal attempts to obtain the first information in the first cell but fails to obtain the first information, it can be determined that the first information of the first cell cannot be obtained. In this case, according to an embodiment of the present disclosure, the first cell may not be directly determined to be in a prohibited state, but it may be further determined whether the first cell is in a prohibited state or in an unprohibited state. That is, if the terminal fails to obtain the first information, the terminal will not directly determine that the first cell is in a prohibited state, but there will be a subsequent determination mechanism to verify the state of the first cell. This is to avoid erroneously determining that the first cell in an unprohibited state is in a prohibited state.

Based on this, it is helpful to avoid determining the first cell as a prohibited state when the first information is in an on-demand state, rather than when the signal quality of the first cell is too poor for the terminal, resulting in few terminals residing in the first cell and wasting wireless resources in the network.

In some embodiments, the first information includes at least one of the following:

System Information Block SIB1;

Synchronization advertising signal block (SS (Synchronization Signal) and PBCH (Physical downlink Broadcast Channel) Block, SSB).

It should be noted that the first information is not limited to the above-mentioned SSB and SIB1, but may also include other information, such as Channel State Information Reference Signal (CSI-RS), Tracking Reference Signal (TRS), Physical Downlink Control Channel (PDCCH), Physical Downlink Shared Channel (PDSCH), and other newly defined signals, such as signals composed of primary synchronization signals and secondary synchronization signals, discovery reference signals (DRS), etc.

In some embodiments, when the terminal determines that the first cell is in a barred state, the terminal may exclude the first cell from the A period of time (e.g., 300 seconds) outside of candidate cells for cell selection or cell reselection. This period of time may be agreed upon by the protocol, indicated by the network device, or determined based on the terminal's capabilities. During this period of time, the terminal will not consider the primary cell when performing cell selection or cell reselection.

In some embodiments, when the terminal determines that the first cell is not in a barred state, if the first terminal can obtain the first configuration information, then the terminal can send a request message to the network device according to the first configuration to request the network device to send the first information. And/or, when the terminal determines that the first cell is not in a barred state, the terminal can determine the first cell as a candidate cell for cell selection or cell reselection, so that the first cell can be considered during cell selection or cell reselection.

For example, the network device may be requested to send the first information in the first cell, or the network device may be requested to send the first information in other cells. When the other cells are not cells under the network device of the first cell, the network device of the first cell may forward the request information to the network devices of the other cells, thereby requesting the network devices of the other cells to send the first information in the other cells.

It should be noted that, in different network devices and/or in different cells, the first configuration information used to send the request information may be the same or different, and this disclosure does not limit this.

The following uses several embodiments to exemplify how a terminal determines the state of a first cell when the terminal cannot obtain the first information of the first cell.

In some embodiments, determining the state of the first cell includes at least one of the following:

determining a state of the first cell according to first indication information of the network device;

determining the state of the first cell according to whether the terminal obtains the first configuration information, for example, the first configuration information may be used by the terminal to send a request message to the network device, where the request message is used to request the network device to send the first information;

The state of the first cell is determined according to the type of the first cell.

It should be noted that the methods for determining the status of the first cell may not be limited to the above methods, and the present disclosure does not impose any restrictions on this.

For example, when a terminal is unable to obtain the first information of a first cell, it may send a request message to a network device based on the first configuration information to request the network device to send the first information in the first cell. Furthermore, the terminal may determine the status of the first cell based on whether the first information can be received in the first cell after sending the request message. For example, if the first information cannot be received in the first cell after sending the request message, it may be determined that the first cell is in a banned state; if the first information can be received in the first cell after sending the request message, it may be determined that the first cell is not in a banned state, and the previous inability to obtain the first information was not due to the first cell being banned, but was due to other reasons.

In some embodiments, the first indication information includes at least one of the following:

Master Information Block (MIB);

Physical Broadcast Channel (PBCH);

Scrambling sequence of the physical broadcast channel.

In some embodiments, spare bits in the MIB may be used as the first indication information.

In some embodiments, a reserved bit in the PBCH may be used as the first indication information.

For example, the reserved bits in the PBCH may include the bits in the PBCH. and/or For example, when communicating in the FR1 frequency band, the reserved bits in the PBCH may include and bit.

In some embodiments, determining the state of the first cell includes at least one of the following:

In response to the terminal communicating in the first frequency range FR1, according to the state of the first cell of the physical broadcast channel;

In response to the terminal communicating in the second frequency range FR2, determining a state of the first cell according to the master information block;

In response to the terminal communicating in the second frequency range FR2, the state of the first cell is determined according to the scrambling code sequence of the physical broadcast channel.

For example, the first frequency domain range may include the FR1 frequency band, and the second frequency domain range may include the FR2 frequency band.

It should be noted that, in the scenarios of communication in the first frequency domain range and communication in the second frequency domain range, determining the state of the first cell may not be limited to the methods shown in the above embodiments, and this disclosure does not limit this. For example, when communicating in the first frequency domain range, the state of the first cell may also be determined based on the MIB, or based on the scrambling code sequence of the PBCH; for example, when communicating in the second frequency domain range, the state of the first cell may also be determined based on the PBCH.

In some embodiments, for example, when the first indication information indicates a first value, the terminal may determine that the state of the first cell is in a prohibited state; for example, when the first indication information indicates a second value, the terminal may determine that the state of the first cell is in a non-prohibited state.

In some embodiments, determining the state of the first cell according to a scrambling code sequence of a physical broadcast channel includes at least one of the following:

determining a state of the first cell according to relevant parameters of a scrambling code sequence of a physical broadcast channel;

The state of the first cell is determined according to an initial value of a scrambling code sequence of a physical broadcast channel.

In some embodiments, the parameters related to the PBCH scrambling code sequence may include, for example, a v value of the PBCH scrambling code sequence (for its specific meaning, please refer to the relevant art, and this disclosure does not elaborate on its meaning here). It should be noted that the parameters related to the PBCH scrambling code sequence are not limited to the v value, and may also be, for example, the length of the PBCH scrambling code sequence, which is not limited in this disclosure.

Take the relevant parameters of the PBCH scrambling code sequence including the v value of the PBCH scrambling code sequence as an example.

For example, the terminal can determine whether the v value belongs to the first value set. If the v value belongs to the first value set, it can be determined that the first cell is in a prohibited state; if the v value does not belong to the first value set, it can be determined that the first cell is in a non-prohibited state.

For example, the terminal can determine the value set to which the v value belongs. If the v value belongs to the first value set, it can be determined that the first cell is in a prohibited state; if the v value belongs to the second value set, it can be determined that the first cell is in a non-prohibited state.

In some embodiments, the relevant parameters are determined based on at least one of the following:

bits in the System Frame Number (SFN);

Half-frame indication bit.

For example, the v value can be determined based on the second least significant bit (LSB) and the third LSB in the SFN, wherein the second LSB and the third LSB can be expressed as and The corresponding relationship between the value x of the second LSB and the value y of the third LSB and the value v can be shown in the following Table 1:

Table 1

For example, the terminal determines the state of the first cell based on the value set to which the v value belongs. For example, the first value set is {0, 1} and the second value set is {2, 3}. When the terminal determines that the v value is 2, it can be determined that the v value belongs to the second value set, and further determines that the first cell is in an unbanned state.

For example, the v value can be determined based on the half-frame indication bit and the 2nd LSB and the 3rd LSB in the SFN, wherein the half-frame indication bit can be expressed as The corresponding relationship between the value z of the half-frame indication bit, the value x of the second LSB, and the value y of the third LSB and the value v can be shown in the following Table 2:

Table 2

For example, the terminal determines the state of the first cell based on the value set to which the v value belongs. For example, the first value set is {0, 1, 2, 3}, and the second value set is {4, 5, 6, 7}. When the terminal determines that the v value is 5, it can be determined that the v value belongs to the second value set, and further determines that the first cell is in an unbanned state.

In some embodiments, the terminal may determine the state of the first cell according to the initial value of the scrambling code sequence of the PBCH.

For example, in the first m-sequence (the specific meaning of which can be found in related art and will not be elaborated herein) corresponding to the scrambling code sequence of the PBCH, if the initial value of x ₁ (n) is determined based on the first method, the terminal can determine that the first cell is in a prohibited state; if the initial value of x ₁ (n) is determined based on the second method, the terminal can determine that the first cell is in a non-prohibited state.

For example, the first manner may include: x ₁ (0)=1, x ₁ (n)=0, n=0, 1, 2, . . . , 30.

For example, the second manner may include: x ₁ (1)=1, x ₁ (n)=0, n=0, 2, 3, . . . , 30.

In some embodiments, determining the state of the first cell according to whether the terminal acquires the first configuration information includes at least one of the following:

In response to the terminal acquiring the first configuration information, determining that the first cell is in an unbarred state;

In response to the terminal failing to acquire the first configuration information, determining that the first cell is in a barred state;

In response to the terminal failing to obtain the first configuration information, it is determined that the first cell is in a prohibited state within a first time period; in response to the terminal obtaining the first configuration information within the first time period, it is determined that the state of the first cell is changed to a non-prohibited state.

In some embodiments, the first configuration information can be used by the terminal to send a request message to the network device to request The network device sends first information.

The request information may request the network device to send the first information in the first cell, or may request the network device to send the first information in other cells. When the other cells are not cells under the network device of the first cell, the network device of the first cell may forward the request information to the network devices of the other cells, thereby requesting the network devices of the other cells to send the first information in the other cells.

It should be noted that, in different network devices and/or in different cells, the first configuration information used to send the request information may be the same or different, and this disclosure does not limit this.

In some embodiments, upon obtaining the first configuration information, the terminal may determine that the first cell is not in a prohibited state. In this case, the terminal may choose to send a request message in the first cell based on the first configuration information to request the network device to send the first information in the first cell. The terminal may also determine that the first cell is a candidate cell for cell selection or cell reselection, thereby determining whether to select or reselect the first cell during cell selection or cell reselection, and not ignoring the first cell.

In some embodiments, if the terminal fails to obtain the first configuration information, it may determine that the first cell is in a prohibited state. In this case, the terminal may exclude the first cell from candidate cells for cell selection or cell reselection for a period of time (e.g., 300 seconds). For example, this period of time may be referred to as a first duration. The first duration may be agreed upon by a protocol, or may be indicated by a network device, or may be determined based on terminal capabilities. The terminal will not consider the first cell during cell selection or cell reselection within the first duration.

It should be noted that, in an embodiment of the present disclosure, the terminal fails to obtain the first configuration information, which may include receiving the first configuration information based on the receiving period of the first configuration information, not receiving the first configuration information in one period, or not receiving the first configuration information in multiple periods of a period number threshold, and it can be determined that the first configuration information has not been received.

In some embodiments, when the terminal fails to obtain the first configuration information, it can determine that the first cell is in a prohibited state and exclude the first cell from candidate cells for cell selection and cell reselection for a period of time. For example, this period of time can be called a first duration.

During the first duration, the terminal may continue to attempt to obtain the first configuration information. If the terminal still fails to obtain the first configuration information within the first duration, the first cell remains in the prohibited state. If the terminal obtains the first configuration information within the first duration, it may be determined that the state of the first cell has changed to the unprohibited state, and thus the first cell may be determined to be a candidate cell for cell selection or cell reselection.

In some embodiments, after obtaining the first configuration information, the terminal may send a request message to the network device based on the first configuration information to request the network device to send the first information. After sending the request message to the network device, the terminal may attempt to receive the first information in the first cell and determine the status of the first cell based on whether the first information is received within the second time period.

For example, the first information is periodic information, and the second duration may include N periods of the first information, which may be agreed upon by a protocol, or may be indicated by a network device, or may be determined based on terminal capabilities.

After sending the request information to the network device, the terminal may attempt to receive the first information in the first cell and determine whether the first information is received within a period of N first information. If the terminal receives the first information within the period of N first information, it may be determined that the first cell is not in a barred state. If the terminal does not receive the first information within the period of N first information, it may be determined that the first cell is in a barred state.

An example is given in which the terminal is in a non-connected state, for example, the terminal is in a radio resource control (RRC) idle (RRC_idle) state or an RRC_inactive state, and the state of the first cell is determined based on whether the terminal obtains the first configuration information.

The request information may also be referred to as a wake-up signal (WUS), and the wake-up signal may request the network device to send the first information. For example, if the network device is in the NES state, causing the first information to be in the on-demand state, the network device will stop sending the first information according to the configuration information of the first information. The wake-up signal may be used to wake up the network device, for example, to request the network device to send the first information, and the network device may adjust the state of the first information to a non-on-demand state, for example, to continue sending the first information according to the configuration information of the first information. Accordingly, the first configuration information may also be referred to as wake-up signal configuration information.

The process of the embodiment of the present disclosure may be as follows:

In step 1:

1>if the UE is in RRC_IDLE or in RRC_INACTIVE (when the terminal is in RRC_IDLE state or RRC_INACTIVE state);

2>if ssb SubcarrierOffset indicates SIB1 is transmitted in the cell (TS 38.213[13]) and if SIB1 acquisition is required for the UE (if ssb SubcarrierOffset indicates SIB1 is transmitted in the cell (based on the cell defined in TS 38.213[13]) and if SIB1 acquisition is required for the UE):

3>acquire the SIB1, which is scheduled as specified in TS 38.213[13];

3>if the UE is unable to acquire the SIB1:

3>if the UE is a NES UE and obtains the WUS configuration (the terminal is an NES terminal (for example, it supports NES functions and obtains WUS configuration information):

4>send WUS and acquire the SIB1 (send WUS and acquire SIB1);

3>else if the UE is a NES UE and does not obtain the WUS configuration (otherwise, if the UE is a NES UE and does not obtain the WUS configuration)

4>If the field in MIB message is set to "allowed"(when the field intraFreqReselection in MIB message is set to "allowed"):

5> the UE may exclude the barred cell as a candidate for cell selection/reselection for up to 300 seconds (the terminal will exclude the barred cell as a candidate for cell selection/reselection within 300 seconds);

4>If the field in MIB message is set to not allowed:

5> the UE may exclude the barred cell as a candidate for cell selection/reselection for up to 300 seconds (the terminal will exclude the barred cell as a candidate for cell selection/reselection within 300 seconds);

5>If the cell operates in licensed spectrum:

6>the UE shall not re-select to another cell on the same frequency as the barred cell and exclude such cell(s) as candidate(s) for cell selection/reselection for 300 seconds.

In some embodiments, the first configuration information is obtained in at least one of the following ways:

Acquiring first configuration information based on a predefined method;

Acquiring first configuration information based on the indication signaling;

Acquire first configuration information in the first cell;

The first configuration information is obtained in cells other than the first cell.

In some embodiments, the terminal may obtain the first configuration information based on a predefined method. For example, the first configuration information may be agreed upon by a protocol, and the terminal may determine the first configuration information based on the agreement.

In some embodiments, the terminal may obtain the first configuration information based on indication signaling. For example, the indication signaling may be indication signaling in the first cell, or the indication information may be indication signaling of a cell other than the first cell, or the indication information may be indication signaling sent by a network device of the first cell, or the indication information may be indication signaling sent by a network device other than the network device of the first cell. The indication signaling may be broadcast signaling or unicast signaling, which is not limited in this disclosure.

In some embodiments, the terminal may obtain the first configuration information in the first cell. For example, the network device may carry the first configuration information in the MIB or DCI in the first cell, wherein the DCI used to carry the first configuration information includes but is not limited to DCI 1_0, such as DCI format 1_0 scrambled by System Information-Radio Network Temporary Identifier (SI-RNTI).

In some embodiments, the terminal may obtain the first configuration information in other cells other than the first cell. For example, the terminal may monitor system information of other cells and obtain the first configuration information from the system information sent by the other cells.

In some embodiments, the terminal may first attempt to obtain the first configuration information in the first cell. If the first configuration information cannot be obtained in the first cell, the terminal may attempt to obtain the first configuration information in the second cell. After obtaining the first configuration information in the second cell, the terminal may send a request message in the first cell based on the first configuration information.

In some embodiments, the type of the first cell includes one of the following:

Cells that support network energy conservation;

Cells that do not support network energy saving;

A cell supporting sending of first information based on an on-demand mode;

A cell that does not support sending the first information based on the on-demand mode;

a cell that sends the first information based on an on-demand mode;

A cell that does not send the first information based on the on-demand mode.

In some embodiments, the terminal can determine the content indicated by the second indication information based on whether the first configuration information is obtained (in this case the second indication information is an implicit indication). For example, if the terminal obtains the first configuration information, it can be determined that the second indication information indicates that the first cell is of a partial type. If the terminal fails to obtain the first configuration information, it can be determined that the second indication information indicates that the first cell is of another partial type.

In some embodiments, determining the state of the first cell according to the type of the first cell includes at least one of the following:

In response to the first cell being a cell that does not support network energy saving, and/or does not support sending the first cell based on the on-demand mode, a cell for which the first information is transmitted, and/or, for a cell which does not transmit the first information based on the on-demand mode, determining that the first cell is in a prohibited state;

In response to the first cell being a cell supporting network energy saving and/or being a cell supporting sending the first information based on an on-demand mode and/or being a cell sending the first information based on an on-demand mode, determining that the first cell is in an unbarred state;

In response to the first cell being a cell supporting network energy saving and/or being a cell supporting sending the first information based on an on-demand mode and/or being a cell sending the first information based on an on-demand mode, and the terminal acquiring the first configuration information, determining that the first cell is in a non-barred state;

In response to the first cell being a cell supporting network energy saving and/or being a cell supporting sending the first information based on an on-demand mode and/or being a cell sending the first information based on an on-demand mode, and the terminal failing to acquire the first configuration information, determining that the first cell is in a prohibited state;

In response to the first cell being a cell supporting network energy saving, and/or being a cell supporting sending first information based on an on-demand mode, and/or being a cell sending first information based on an on-demand mode, and the terminal failing to obtain the first configuration information, it is determined that the first cell is in a prohibited state within a first time period, and in response to the terminal obtaining the first configuration information within the first time period, it is determined that the state of the first cell is changed to a non-prohibited state.

In some embodiments, in order to simplify the description, a cell that does not support network energy saving, and/or a cell that does not support sending first information based on an on-demand mode, and/or a cell that does not send first information based on an on-demand mode can be described as a first cell of the first type; and a cell that supports network energy saving, and/or a cell that supports sending first information based on an on-demand mode, and/or a cell that sends first information based on an on-demand mode can be described as a first cell of the second type.

For example, when the terminal fails to obtain the first information in the first cell, the terminal can determine the type of the first cell. If the first cell belongs to the first type, it can be determined that the first cell did not receive the first information of the first cell, and it is not caused by the first cell supporting NES (for example, because the network device stops sending the first information in NES mode), and/or, it is not caused by the first cell supporting the sending of the first information based on the on-demand mode (for example, because the network device is in NES mode and the first information is in on-demand mode), and/or, it is not caused by the first cell sending the first information based on the on-demand mode (for example, the first information in the first cell stops sending because it is in on-demand mode). Then it is highly likely that the signal quality of the first cell is very poor for the terminal, resulting in the terminal failing to receive the first information in the first cell. Therefore, it can be determined that the first cell is in a prohibited state.

For example, when the terminal fails to obtain the first information in the first cell, the terminal can determine the type of the first cell. If the first cell belongs to the second type, it can be determined that the first cell did not receive the first information of the first cell, which may be due to the first cell supporting NES (for example, because the network device stops sending the first information in NES mode), and/or, it may be due to the first cell supporting the sending of the first information based on the on-demand mode (for example, because the network device is in NES mode and the first information is in on-demand mode), and/or, it may be due to the first cell sending the first information based on the on-demand mode (for example, the first information in the first cell stops sending because it is in on-demand mode), rather than because the signal quality of the first cell is very poor for the terminal, resulting in the terminal failing to receive the first information in the first cell. Therefore, it can be determined that the first cell is in an unbanned state.

In some embodiments, when the terminal determines that the type of the first cell is the first type, it may determine that the first cell is in a prohibited state. In this case, the terminal may exclude the first cell from candidate cells for cell selection or cell reselection for a period of time (e.g., 300 seconds). For example, this period of time may be referred to as a first duration. The first duration may be agreed upon by a protocol, or may be indicated by a network device, or may be determined based on terminal capabilities. The terminal will not consider the first cell when performing cell selection or cell reselection within the first duration.

In some embodiments, when the terminal determines that the type of the first cell is the second type, it can determine that the first cell is in an unbanned state. In this case, the terminal can choose to send request information in the first cell according to the first configuration information to request the network device to send the first information in the first cell; the terminal can also determine that the first cell It is a candidate cell for cell selection and cell reselection, so that when performing cell selection and cell reselection, it can be determined whether it is necessary to select or reselect to the first cell, and the first cell will not be ignored.

In some embodiments, when the terminal determines that the type of the first cell is the second type, it can further determine whether the terminal has obtained the first configuration information. If the terminal obtains the first configuration information, it can be determined that the first cell is in an unbanned state. If the terminal fails to obtain the first configuration information, it can be determined that the first cell is in a banned state.

In some embodiments, when the terminal determines that the type of the first cell is the second type, if the first configuration information cannot be obtained, it can determine that the first cell is in a prohibited state and exclude the first cell from the candidate cells for cell selection and cell reselection for a period of time. For example, this period of time can be called the first duration.

During the first duration, the terminal may continue to attempt to obtain the first configuration information. If the terminal still fails to obtain the first configuration information within the first duration, the first cell remains in the prohibited state. If the terminal obtains the first configuration information within the first duration, it may be determined that the state of the first cell has changed to the unprohibited state, and thus the first cell may be determined to be a candidate cell for cell selection or cell reselection.

In some embodiments, when the terminal determines that the type of the first cell is the second type, if the terminal obtains the first configuration information, it can send a request message to the network device according to the first configuration information to request the network device to send the first information. After sending the request message to the network device, the terminal can attempt to receive the first information in the first cell and determine the status of the first cell based on whether the first information is received within the second time period.

For example, the first information is periodic information, and the second duration may include N periods of the first information, which may be agreed upon by a protocol, or may be indicated by a network device, or may be determined based on terminal capabilities.

After sending the request information to the network device, the terminal may attempt to receive the first information in the first cell and determine whether the first information is received within a period of N first information. If the terminal receives the first information within the period of N first information, it may be determined that the first cell is not in a barred state. If the terminal does not receive the first information within the period of N first information, it may be determined that the first cell is in a barred state.

In some embodiments, the type of the first cell is determined based on at least one of the following:

Second indication information of the network device;

an identifier of the first cell;

The frequency band where the first cell is located.

In some embodiments, the type of the first cell may be determined based on a predefined rule, or may be indicated by a network device.

In some embodiments, the second indication information includes at least one of the following:

For example, when it is determined that the identifier of the first cell does not belong to the identifier set, it may be determined that the first cell is of the first type, that is, the first cell is a cell that does not support network energy saving, and/or, a cell that does not support sending the first information based on the on-demand mode, and/or, a cell that does not send the first information based on the on-demand mode. When it is determined that the identifier of the first cell belongs to the identifier set, it may be determined that the first cell is of the second type, that is, the first cell is a cell that supports network energy saving, and/or, a cell that supports sending the first information based on the on-demand mode, and/or, a cell that sends the first information based on the on-demand mode.

In some embodiments, the second duration in the above embodiments may be associated with a cell. For example, the second durations corresponding to different cells may be different or the same.

In some embodiments, it is considered that the network device determines whether to notify the sending of the first information mainly based on the number of terminals connected and the business conditions, such as sending the first information on demand. For example, if it is not working hours, the number of terminals connected is relatively small and the business demand is relatively small, the network device stops sending the first information and sends the first information after receiving the request information; correspondingly, if it is working hours, the number of terminals connected is relatively large and the business demand is relatively large, the network device sends the first information based on the normal mode (for example, sending the first information according to the configuration information of the first information). Therefore, the cell type may change at different times.

On this basis, in some embodiments, when the terminal determines that the first cell is of the second type based on that the identifier of the first cell belongs to the identifier set, it can be determined that the first cell is of the second type within a period of time t, and that the first cell is of the first type outside of time t.

In some embodiments, a terminal supporting network energy saving receives indication information and determines the corresponding cell status when SIB1 cannot be obtained. Correspondingly, the network device transmits indication information for the terminal to determine the corresponding cell status when SIB1 cannot be obtained. The following is a specific invention scheme based on different indication information;

Embodiment 1.1: The indication information is based on the reserved bit indication carried by the MIB and/or PBCH.

Based on different SSB patterns and frequency domain ranges, the reserved bits carried by PBCH are shown in Table 3 below:

Table 3

For example, in the FR1 licensed scenario, the reserved bits carried by the PBCH are

Exemplarily, the indication information is based on the Bit or Bit indication.

Exemplarily, the indication information is based on the spare bit indication in the MIB.

For example, in FR1 scenario, the indication information is based on the PBCH carried Bit or Bit indication; in the FR2 scenario, the indication information is based on the spare bit indication in the MIB.

For example, in FR1 scenario, the indication information is based on the PBCH carried Bit or Bit indication; in the FR2 scenario, the indication information is determined based on the scrambling method of the PBCH. For the specific scrambling method, see Example 1.2.

Exemplarily, when the indication information indicates a first value, e.g., 0, the terminal determines that the cell is in a barred state and excludes the cell from a range of candidate cells for cell selection/reselection for a first time length, where the first time length is determined based on a predefined method, signaling configuration, or UE capability. Exemplarily, the first time length is equal to 300 seconds. During the first time length, the terminal will not choose to camp on the current cell.

Exemplarily, when the indication information indicates a second value, e.g., the indication is 1, the terminal determines that the cell is in a not barred state and includes the cell in a range of candidate cells for cell selection/reselection;

Exemplarily, if the terminal determines that the cell is in the not barred state, under the condition that the terminal obtains the first configuration information, the terminal sends a trigger message to trigger the network device to send SIB1 and attempt to receive SIB1. The first configuration information is based on the above definition and will not be repeated here; correspondingly, if the network device receives the trigger information, it can start transmitting SIB1.

Example 1.2: The indication information is based on the PBCH scrambling method.

Exemplarily, the indication method is determined based on the v value of the PBCH scrambling sequence. For users supporting network energy saving, if the v value belongs to a first value set, the terminal determines that the cell is in a barred state; if the v value belongs to a second value set, the terminal determines that the cell is in a not barred state;

For example, the first value set is {0, 1}, and the second value set is {2, 3}, and the corresponding v value is based on the 2nd and 3rd LSB of SFN (ie, ) is determined, and the corresponding relationship is shown in Table 1 above.

For example, the first value set is {0, 1, 2, 3}, and the second value set is {4, 5, 6, 7}, and the corresponding v value is based on the half-frame indication bit, ie, The corresponding relationship is shown in Table 2 above.

Exemplarily, the indication method is determined based on an initial value of a PBCH scrambling sequence. Exemplarily, if an initial value of a first m-sequence x ₁ (n) corresponding to the PBCH scrambling sequence is determined based on the following method: x ₁ (0) = 1, x ₁ (n) = 0, n = 0, 1, 2, ..., 30, the terminal determines that the cell is in a barred state; if the initial value of x ₁ (n) is determined based on the following method: x ₁ (1) = 1, x ₁ (n) = 0, n = 0, 2, 3, ..., 30, the terminal determines that the cell is not in a barred state.

Exemplarily, if the terminal determines that the cell is in a barred state and excludes the cell from a range of candidate cells for cell selection/reselection for a first time length, the first time length being determined based on a predefined method, signaling configuration, or UE capability, and exemplarily, the first time length being equal to 300s. During the first time length, the terminal will not choose to camp on the current cell;

Exemplarily, if the terminal determines that the cell is in the not barred state, the terminal obtains the first configuration information Under the condition of the information, the terminal sends a trigger message to trigger the network device to send SIB1 and try to receive SIB1. The first configuration information is based on the above definition and will not be repeated here. Correspondingly, if the network device receives the trigger information, it can start transmitting SIB1.

Embodiment 1.3: The terminal determines the state of the current cell based on whether the first configuration information corresponding to the current cell is obtained.

Exemplarily, the configuration information is used by the terminal to send trigger information to trigger the transmission of cell system information; exemplary, the configuration information may be a WUS configuration, and the trigger information may be a WUS. The terminal may obtain the first configuration information based on other cell indication information, or based on the current cell indication information, or based on a predefined method, and the present invention is not limited thereto.

For example, if the terminal obtains the WUS configuration corresponding to the current cell, the terminal determines that the corresponding SIB1 can be obtained by sending the WUS. The terminal determines that the cell is in the not-barred state, and the terminal sends the WUS, triggering the network device to send SIB1 and attempt to receive SIB1. Correspondingly, if the network device receives the trigger information, it can start transmitting SIB1.

Exemplarily, if the terminal does not obtain the WUS configuration corresponding to the current cell, the terminal determines that it cannot obtain the corresponding SIB1 based on the method of sending the WUS. The terminal determines that the cell is in a barred state and excludes the cell from the range of cell selection/reselection candidate cells for a first time length, the first time length being determined based on a predefined method, signaling configuration, or UE capability. Exemplarily, the first time length is equal to 300s. During the first time length, the terminal will not choose to stay in the current cell;

Exemplarily, if the terminal does not obtain the WUS configuration corresponding to the current cell, the terminal determines that it cannot obtain the corresponding SIB1 based on the method of sending WUS. The terminal determines that the cell is in a barred state and temporarily excludes the cell from the range of cell selection/reselection candidate cells for a first time length. The first time length is determined based on a predefined method, signaling configuration or UE capability. Exemplarily, the first time length is equal to 300s. Within the first time length,

If the terminal does not obtain the WUS configuration corresponding to the current cell, the terminal will not choose to camp on the current cell;

If the terminal obtains the WUS configuration corresponding to the current cell within the first time length, the terminal updates the current cell status to the not barred status, sends the WUS, triggers the network device to send SIB1, and attempts to receive SIB1; correspondingly, if the network device receives the trigger information, it can start transmitting SIB1.

Exemplarily, if the terminal obtains the WUS configuration corresponding to the current cell, the terminal determines whether the cell is in a barred state based on the second condition, specifically including:

If the terminal fails to obtain SIB1 information after N SIB1 configuration cycles after sending the WUS, the terminal determines that the cell is in the barred state; otherwise, the terminal determines that the cell is in the not barred state;

After the terminal sends a WUS, if SIB1 is not obtained, the terminal continues to send WUS. After sending WUS N times, if SIB1 information is still not obtained, the terminal determines that the cell is in the barred state. Otherwise, the terminal determines that the cell is in the not barred state.

The N is determined based on pre-definition, signaling configuration or a pre-defined method.

In some embodiments, a terminal supporting network energy saving determines a cell type, and based on the cell type, determines a corresponding cell state when SIB1 cannot be acquired.

Embodiment 2.1: A terminal supporting network energy saving determines a cell type based on indication information and, based on the cell type, determines a corresponding cell state when SIB1 cannot be obtained.

Correspondingly, the network device sends indication information to indicate the corresponding cell type.

Exemplarily, the indication information is based on MIB and/or PBCH reserved bit indication, and the specific indication method is referenced. Consider Example 1.1, which will not be described in detail here;

Exemplarily, the indication information is indicated based on the PBCH scrambling method. For the specific indication method, refer to Example 1.2 and will not be repeated here.

Exemplarily, the indication information is based on whether the WUS configuration indication is obtained. For specific indication methods, refer to Example 1.3 and will not be repeated here.

Exemplarily, if the indication information indicates that the cell type is a cell supporting network energy saving and/or a cell supporting sending system information in an on-demand mode, when the terminal cannot obtain SIB1, the terminal determines that the cell is in a not barred state and includes the cell in a range of candidate cells for cell selection/reselection;

Exemplarily, if the terminal determines that the cell is in the not barred state, under the condition that the terminal obtains the first configuration information, the terminal sends a trigger message to trigger the network device to send SIB1 and attempt to receive SIB1. The first configuration information is based on the above definition and will not be repeated here; correspondingly, if the network device receives the trigger information, it can start transmitting SIB1.

Exemplarily, if the terminal determines that the cell is in a not barred state, under the condition that the terminal has not obtained the first configuration information, the terminal searches for other cells and attempts to receive system information of other cells to obtain the first configuration information corresponding to the current cell.

Exemplarily, if the indication information indicates that the cell type is a cell supporting network energy saving and/or a cell supporting sending system information in an on-demand mode, when the terminal cannot obtain SIB1, if the terminal obtains the WUS configuration corresponding to the current cell, the terminal determines that the cell is in a not barred state and includes the cell in a range of candidate cells for cell selection/reselection;

Exemplarily, if the indication information indicates that the cell type is a cell supporting network energy saving and/or a cell supporting on-demand mode transmission of system information, when the terminal is unable to obtain SIB1, if the terminal does not obtain the WUS configuration corresponding to the current cell, the terminal determines that the cell is in a barred state and excludes the cell from the range of cell selection/reselection candidate cells for a first time length, the first time length being determined based on a predefined method, signaling configuration, or UE capability, and exemplarily, the first time length is equal to 300s. During the first time length, the terminal will not choose to camp on the current cell;

Exemplarily, if the indication information indicates that the cell type is a cell that supports network energy saving and/or a cell that supports sending system information in an on-demand mode, when the terminal cannot obtain SIB1, if the terminal does not obtain the WUS configuration corresponding to the current cell, the terminal determines that it cannot obtain the corresponding SIB1 based on the method of sending WUS. The terminal determines that the cell is in a barred state and temporarily excludes the cell from the range of cell selection/reselection candidate cells for a first time length. The first time length is determined based on a predefined method, signaling configuration or UE capability. Exemplarily, the first time length is equal to 300s. Within the first time length,

If the terminal does not obtain the WUS configuration corresponding to the current cell, the terminal will not choose to camp on the current cell;

If the terminal obtains the WUS configuration corresponding to the current cell within the first time length, the terminal updates the current cell status to the not barred status, includes the cell in the cell selection/reselection range, sends the WUS, triggers the network device to send SIB1, and attempts to receive SIB1; correspondingly, if the network device receives the trigger information, it can start transmitting SIB1.

Embodiment 2.2: A terminal supporting network energy saving determines a cell type based on a predefined method and, based on the cell type, determines a corresponding cell state when SIB1 cannot be obtained.

Exemplarily, the terminal determines whether the cell is a cell supporting network energy saving and/or a cell supporting on-demand mode transmission of system information based on whether the cell ID belongs to the first set. That is, if the cell ID belongs to the first set, the terminal determines that the cell is a cell supporting network energy saving and/or a cell supporting on-demand mode transmission of system information, and vice versa. Yes;

Exemplarily, the terminal determines whether the cell is a cell supporting network energy saving and/or a cell supporting on-demand transmission of system information based on whether the cell band belongs to the first set. That is, if the cell band belongs to the first set, the terminal determines that the cell is a cell supporting network energy saving and/or a cell supporting on-demand transmission of system information, and vice versa.

Exemplarily, the first set is determined based on a signaling indication or a predefined manner;

In one scenario, network equipment determines whether to send system information on demand based primarily on the number of connected users and service conditions. For example, during non-working hours, when the number of connected users is relatively small and service demand is relatively low, the network equipment stops sending system information and only sends system information after receiving a trigger message. Conversely, during working hours, when the number of connected users is relatively large and service demand is relatively high, the network equipment sends system information in a normal mode. Therefore, the cell type may change over time.

Based on the above background, in another possible implementation, within a first time period, the terminal determines whether the cell is a cell that supports network energy saving and/or a cell that supports on-demand transmission of system information based on whether the cell ID belongs to a first set. That is, if the cell ID belongs to the first set, the terminal determines that the cell is a cell that supports network energy saving and/or a cell that supports on-demand transmission of system information, and vice versa.

Outside the first time period, the terminal determines that the cell is a cell that does not support network energy saving and/or a cell that does not send system information based on an on-demand mode;

Based on the above background, in another possible implementation, within a first time period, the terminal determines whether the cell is a cell that supports network energy saving and/or a cell that supports on-demand transmission of system information based on whether the band to which the cell belongs belongs to the first set. That is, if the cell belongs to the first set, the terminal determines that the cell is a cell that supports network energy saving and/or a cell that supports on-demand transmission of system information, and vice versa.

The first time length is determined based on a predefined method, signaling configuration or UE capability. Exemplarily, the first time length is equal to 300s. Within the first time length,

If the terminal does not obtain the WUS configuration corresponding to the current cell, the terminal will not choose to camp on the current cell;

If the terminal obtains the WUS configuration corresponding to the current cell within the first time length, the terminal updates the current cell status to the not barred status, includes the cell in the cell selection/reselection range, sends the WUS, triggers the network device to send SIB1, and attempts to receive SIB1; correspondingly, if the network device receives the trigger information, it can start transmitting SIB1.
