[0001] Cross-reference to related applications

[0002] This application claims priority to Chinese Patent Application No. 202510137925.9, filed on February 7, 2025, entitled “Method, Terminal and Network Side Device for Listening to and Transmitting Physical Downlink Control Channel”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application belongs to the field of wireless communication technology, specifically relating to a method for monitoring and transmitting physical downlink control channels, a method for acquiring and transmitting uplink signal configurations, a terminal, and network-side equipment. Background Technology

[0004] Network energy saving (NES) technology refers to reducing unnecessary uplink / downlink, time domain / frequency domain / spatial domain transmissions to achieve network energy saving while minimizing impact on user equipment (UE) services or system performance.

[0005] In network energy-saving scenarios, the UE requests On-demand System Information Block 1 (OD-SIB1) by sending an Uplink Wake Up Signal (UL-WUS). However, in this scenario, after the network side starts sending System Information Block 1 (SIB1), there is currently no solution for how the UE listens to and schedules the Type 0 Physical Downlink Control Channel (PDCCH) for SIB1. Furthermore, the uplink signal configuration used to request the energy-saving cell's SIB1 transmission is provided by the system information block. If there are too many uplink signal configuration information fields, or too many forcibly configured information fields, it will increase overhead. Summary of the Invention

[0081] The following description, in conjunction with the accompanying drawings, details the method, terminal, and network-side equipment for monitoring and transmitting the physical downlink control channel provided in this application, through some embodiments and application scenarios.

[0082] Figure 2 is a flowchart illustrating a method for monitoring the physical downlink control channel provided in an embodiment of this application. This method 200 can be executed by a terminal. As shown in Figure 2, the method may include the following steps.

[0083] S202: The terminal sends a first uplink signal, which is used to request the transmission of at least one of the downlink signal, downlink channel and system information block of the first cell.

[0084] In this embodiment of the application, the first uplink signal includes, but is not limited to, UL-WUS, etc.

[0085] In this embodiment, the first cell can be a cell that periodically transmits at least one of downlink signals, downlink channels, and system information blocks, such as an NES cell that periodically transmits Type 0 PDCCH. Alternatively, the first cell can be a cell that allows terminals to request the transmission of at least one of downlink signals, downlink channels, and system information blocks on demand, such as an NES cell that allows terminals to request OD-SIB1 on demand.

[0086] In this embodiment, the downlink channel requested by the first uplink signal includes, but is not limited to, Type 0 Physical Downlink Control Channel (PDCCH), etc., and is not specifically limited. The system information block requested by the first uplink signal includes, but is not limited to, System Information Block 1 (SIB1), etc., and is not specifically limited.

[0087] S204: The terminal listens to at least one of the following in the first cell: downlink signal, downlink channel, and system information block.

[0088] The start time of terminal listening can include one of the following:

[0089] 1) The first moment;

[0090] 2) Second moment;

[0091] 3) The later of the first and second time points;

[0092] 4) The earlier of the first and second moments.

[0093] The first moment is a moment after the reference point, and the second moment is a moment after receiving the first uplink signal feedback.

[0094] The scenario described above, in which the listening is initiated at the later of the first and second moments, takes into account the reception of the first uplink signal feedback, which helps in the successful decoding of the first uplink signal feedback. This avoids the situation where the terminal starts listening before successfully receiving the first uplink signal feedback, thus preventing the terminal from wasting power due to premature listening and saving the terminal's power.

[0095] In one implementation, the reference point may be the start or end time slot of the receiving window for the first uplink signal feedback.

[0096] In one implementation, the reference point can be the start or end time slot of the first uplink signal feedback RAR receiving window.

[0097] In this embodiment of the application, the aforementioned first moment may include one of the following:

[0098] 1) The Xth time unit after the reference point, where X is a positive integer.

[0099] For example, if X is 5 and the time unit is a time slot, the terminal can start listening to at least one of the downlink signal, downlink channel, and system information block of the first cell in the 5th time slot after the reference point.

[0100] 2) When the first timer starts at the reference point and times out, the duration of the first timer is Y time units, where Y is a positive integer.

[0101] For example, Y is 3, the time unit is a symbol, the terminal starts the first timer at the reference point, the duration of the first timer is 3 symbols, when the first timer expires, the terminal starts listening to at least one of the downlink signal, downlink channel and system information block of the first cell.

[0102] 3) The timing of the first type 0 PDCCH after the Zth time unit following the reference point, where Z is a positive integer.

[0103] For example, if Z is 2 and the time unit is PDCCH timing, the terminal can start listening to at least one of the downlink signals, downlink channels, and system information blocks of the first cell at the timing of the first Type 0 PDCCH after the second PDCCH timing after the reference point.

[0104] For example, if Z is 3 and the time unit is a time slot, the terminal can start listening to at least one of the downlink signal, downlink channel, and system information block of the first cell at the time of the first Type 0 PDCCH after the third time slot after the reference point.

[0105] 4) The timing of the Mth type 0 PDCCH after the reference point, where M is a positive integer.

[0106] For example, if M is 6, the terminal can start listening to at least one of the downlink signals, downlink channels, and system information blocks of the first cell at the 6th Type 0 PDCCH after the reference point.

[0107] In cases where the reference point includes multiple time units, "after the reference point" can refer to the last time unit within the reference point, or it can refer to a specific time unit within the reference point; the specific meaning is not limited.

[0108] For example, a reference point may include multiple time slots. The term "after the reference point" could refer to the last time slot within the reference point, or it could refer to the third-to-last time slot within the reference point, etc.

[0109] For example, a reference point includes one time slot, and one time slot includes 12 symbols. The "after the reference point" could refer to the last symbol in the reference point time slot, or it could refer to the third to last symbol in the reference point time slot, etc.

[0110] Wherein, at least one of X, Y, Z and M is predefined by the protocol; or, at least one of X, Y, Z and M is indicated by one of the following: by configuration indication of the first uplink signal, by feedback indication of the first uplink signal, or by indication of a Random Access Response (RAR).

[0111] In this embodiment of the application, the second moment mentioned above may include one of the following:

[0112] 1) The time unit for receiving the first uplink signal feedback;

[0113] 2) The Oth time unit after receiving the first uplink signal feedback time unit, where O is a positive integer;

[0114] 3) The time when the second timer expires, wherein the second timer starts when the first uplink signal feedback is received, and the duration of the second timer is P time units, where P is a positive integer;

[0115] 4) The timing of the first type 0 PDCCH after the Qth time unit following the reception of the first uplink signal feedback, where Q is a positive integer;

[0116] 5) The timing of the Nth type 0 PDCCH after receiving the feedback of the first uplink signal, where N is a positive integer.

[0117] Wherein, at least one of the above O, P, Q and N is predefined by the protocol; or, at least one of the above O, P, Q and N is indicated by one of the following: indicated by the configuration of the first uplink signal, indicated by the feedback of the first uplink signal, indicated by RAR.

[0118] In this application embodiment, the above-mentioned time unit may include one of the following: symbol, slot, millisecond, second, frame, half frame, system frame, PDCCH occasion.

[0119] In this embodiment of the application, the step S204 described above may further include:

[0120] The terminal stops listening to at least one of the following in the first cell: downlink signal, downlink channel, and system information block, at the end of the first time window. The start time of the first time window may include one of the following:

[0121] 1) The first moment;

[0122] 2) Second moment;

[0123] 3) The later of the first and second time points;

[0124] 4) The earlier of the first and second moments.

[0125] In this embodiment, the first time window refers to a time window used to receive at least one of the downlink signal, downlink channel, and system information block of the first cell. The duration of the first time window can be predefined by the protocol, indicated by the configuration of the first uplink signal, or indicated by feedback from the first uplink signal. The duration of the first time window may include one or more time units.

[0126] In this embodiment of the application, the above method may further include:

[0127] The terminal acquires the configuration of the first uplink signal. The configuration of the first uplink signal is indicated by the system information block of the first cell or the second cell, wherein the second cell is the cell that periodically sends system information block 1.

[0128] The configuration for the terminal to obtain the first uplink signal can include two scenarios. Scenario 1: The terminal is camped in an NES cell and obtains the WUS configuration of the current NES cell. Scenario 2: The UE is camped in another cell (cell A) and obtains the WUS configuration of another NES cell in cell A.

[0129] In the first scenario mentioned above, some parameters in the WUS configuration can be left unconfigured, such as uplink frequency information. The terminal can directly use the parameter values ​​obtained from the SIB1 of the NES cell when it is camped on the NES cell. Therefore, the network side does not need to configure these parameters, which can save overhead.

[0130] For example, the first cell is an energy-saving cell (NES cell). After the UE camps on the NES cell, the UE receives the updated WUS configuration from the NES cell. That is, the WUS configuration is indicated by the first cell. Specifically, the WUS configuration can be indicated by the SIB X of the first cell.

[0131] For example, the second cell is a non-energy-efficient cell, cell A, which periodically sends SIB1. After the UE camps on the second cell, cell A, the UE receives the WUS configuration of the energy-efficient cell, NES cell. That is, the WUS configuration is indicated by the second cell. Specifically, the WUS configuration can be indicated by the SIB X of the second cell.

[0132] In some embodiments, the second cell is a cell that periodically transmits SIB1, and the first cell is a cell that non-periodically transmits SIB1.

[0133] In some embodiments, the second cell is a cell that periodically transmits SIB1, and the first cell is a cell that allows on-demand requests for SIB1 transmission.

[0134] In some embodiments, the first uplink signal is WUS, an uplink wake-up signal, used to request the transmission of system information blocks for the energy-saving cell.

[0135] In some embodiments, the first uplink signal is configured as a WUS configuration, which includes various parameters required for UL-WUS transmission.

[0136] For example, the WUS configurations for the target NES cell obtained by the UE from the first cell and the second cell are different. This includes the fact that the information fields included in the WUS configurations may be different, and the values ​​of the information fields in the specific WUS configurations may also be different. The UE sends UL-WUS based on the latest obtained WUS configuration associated with the target NES cell to request the transmission of SIB1 of the target NES cell.

[0137] For example, the WUS configuration obtained by the UE from the first cell does not include an information field related to uplink frequency information. The UE directly determines the uplink frequency-related information of UL-WUS based on the uplink frequency information of the first cell.

[0138] For example, the WUS configuration obtained by the UE from the second cell may optionally include an information field related to uplink frequency information, and the UE determines the uplink frequency related information of UL-WUS based on the uplink frequency information of the WUS configuration.

[0139] For example, the configuration of the first uplink signal can be a UL-WUS configuration.

[0140] It is worth mentioning that in step S202 above, the terminal can send the first uplink signal in the first cell or in the second cell, and the specific method is not limited.

[0141] In this embodiment of the application, the configuration of the first uplink signal may include a target parameter set, which may include at least one of the following target parameters:

[0142] 1) The physical cell identifier (PhysCellId) associated with the configuration of the first uplink signal;

[0143] 2. The list of physical cell identifiers (PhysCellIdList) associated with the configuration of the first uplink signal;

[0144] 3) Physical Random Access Channel Configuration Identifier Prach-ConfigurationIndex;

[0145] 4) The number of frequency domain opportunities for the Random Access Channel Occasion (RO) msg1-FDM;

[0182] 41) Second information field, the second information field being used to indicate that the configuration of the first uplink signal is applicable to the first cell or at least one second cell.

[0183] In this embodiment of the application, if the configuration of the first uplink signal does not include the target parameter, the terminal may use the value of the corresponding parameter in the cell that provides the configuration of the first uplink signal.

[0184] In some embodiments, when the target parameter set does not contain target parameters, the UE refers to the corresponding parameter values ​​in SIB1 of the cell providing WUS configuration.

[0185] In this embodiment of the application, the above method may further include:

[0186] Based on the Physical Cell Identifier (PhysCellId) and Absolute Radio Frequency Channel Number (ARFCN-ValueNR) in the configuration of the first uplink signal, the terminal determines whether the configuration of the first uplink signal is applicable to the first cell.

[0187] In one implementation, the terminal determines whether the configuration of the first uplink signal is applicable to the first cell based on the Physical Cell Identifier (PhysCellId) and the Absolute Radio Frequency Channel Number (ARFCN-ValueNR) in the configuration of the first uplink signal. This may include:

[0188] If the Physical Cell Identifier PhysCellId in the configuration of the first uplink signal is consistent with the Physical Cell Identifier PhysCellId of the first cell, and the Absolute Radio Frequency Channel Number ARFCN-ValueNR in the configuration of the first uplink signal is consistent with the Absolute Radio Frequency Channel Number ARFCN-ValueNR of the first cell, the terminal assumes that the configuration of the first uplink signal is applicable to the first cell.

[0189] In this embodiment of the application, the above method may further include:

[0190] The terminal determines whether the configuration of the first uplink signal is applicable to the first cell based on the first information field or the second information field in the configuration of the first uplink signal.

[0191] In one implementation, the terminal determines whether the configuration of the first uplink signal is applicable to the first cell based on the first information field or the second information field in the configuration of the first uplink signal, which may include:

[0192] If the first information field or the second information field in the configuration of the first uplink signal indicates that the configuration of the first uplink signal applies to the first cell, the terminal assumes that the configuration of the first uplink signal applies to the first cell.

[0193] In this embodiment of the application, the above method may further include:

[0194] The terminal determines whether the configuration of the first uplink signal is applicable to the first cell by whether it configures a physical cell identifier (PhysCellId) or a physical cell identifier list (PhysCellIdList) in the configuration of the first uplink signal.

[0195] In one implementation, the terminal determines whether the configuration of the first uplink signal is applicable to the first cell based on whether a physical cell identifier (PhysCellId) or a physical cell identifier list (PhysCellIdList) is configured in the configuration of the first uplink signal. This determination may include:

[0196] If the Physical Cell Identifier (PhysCellId) or Physical Cell Identifier List (PhysCellIdList) is not configured in the configuration of the first uplink signal, the terminal assumes that the configuration of the first uplink signal applies to the first cell.

[0197] In this embodiment of the application, when the terminal assumes that the configuration of the first uplink signal is applicable to the first cell, the values ​​of some target parameters in the target parameter set included in the configuration of the first uplink signal are referenced to the values ​​of the corresponding parameters in the first cell.

[0198] For example, the UE can determine whether the WUS configuration applies to a first cell or at least one second cell based on the following methods.

[0199] Method 1: The UE determines whether the WUS configuration applies to the current serving cell or other NES cells based on the Physical Cell Id and Absolute Radio Frequency Channel Number (ARFCN-ValueNR) in the WUS configuration. For example, if the Physical Cell Id in the WUS configuration is the same as the Physical Cell Id of the current serving cell, and the Absolute Radio Frequency Channel Number (ARFCN-ValueNR) in the WUS configuration is the same as the Absolute Radio Frequency Channel Number (ARFCN-ValueNR) of the current serving cell, the UE assumes that the WUS configuration applies to the current serving cell.

[0200] Method 2: The WUS configuration explicitly indicates whether the WUS configuration applies to the current serving cell or other cells. For example, by adding a first information domain and a second information domain, the UE determines whether the WUS configuration applies to the current serving cell or other cells based on the indication of the first information domain or the second information domain.

[0201] Method 3: The UE determines whether the WUS configuration is applicable to the currently serving cell based on whether the Physical Cell Identifier (PhysCellId) or the Physical Cell Identifier List (PhysCellIdList) is configured in the WUS configuration. For example, if the WUS configuration contains a PhysCellIdList field, the UE considers the WUS configuration applicable to other cells; if the WUS configuration does not contain a PhysCellIdList field, the UE considers the WUS configuration applicable to the currently serving cell.

[0202] In this embodiment, the frequency domain timing start position offset msg1-FrequencyStart of the random access channel timing includes: the frequency domain start position of the random access channel timing RO that allows the transmission of UL-WUS, and the offset at the RB granularity relative to the first resource block RB of the terminal carrier. The terminal carrier is determined by the carrier offset offsetToCarrier and the absolute frequency point A absoluteFrequencyPointA in the configuration of the first uplink signal. The subcarrier spacing of the RB granularity offset references ULSubCarrierSpacing in the WUS configuration; if ULSubCarrierSpacing is not configured in the WUS configuration, the subcarrier spacing of the uplink initial BWP of the cell providing the WUS configuration is referenced.

[0203] The physical downlink control channel monitoring method provided in this application embodiment involves a terminal sending a first uplink signal, which requests the transmission of at least one of the downlink signal, downlink channel, and system information block of a first cell. The terminal monitors at least one of the downlink signal, downlink channel, and system information block of the first cell, and the monitoring start time includes one of the following: a first time, a second time, a later time between the first and second times, or an earlier time between the first and second times. Wherein, the first time is a time after a reference point, and the second time is a time after receiving the feedback of the first uplink signal, providing a solution for monitoring at least one of the downlink signal, downlink channel, and system information block.

[0204] Figure 3 is a flowchart illustrating a method for monitoring the physical downlink control channel provided in an embodiment of this application. This method 300 can be executed by a terminal. As shown in Figure 3, the method may include the following steps.

[0205] S302: The terminal sends a first uplink signal, which is used to request the transmission of at least one of the downlink signal, downlink channel and system information block of the first cell.

[0206] In this embodiment, the first cell can be a cell that non-periodically transmits at least one of downlink signals, downlink channels, and system information blocks; or, the first cell can be a cell that allows terminals to request the transmission of at least one of downlink signals, downlink channels, and system information blocks on demand. Alternatively, the first cell can be understood as an energy-saving cell. Alternatively, the first cell can be a cell that non-periodically transmits SIB1. Alternatively, the first cell can be a cell that allows UEs to send uplink wake-up signals to request the transmission of SIB1.

[0207] In this embodiment, the downlink channel requested by the first uplink signal includes, but is not limited to, Type 0 PDCCH, etc., and is not specifically limited. The system information block requested by the first uplink signal includes, but is not limited to, SIB1, etc., and is not specifically limited.

[0208] S304: The terminal begins listening to at least one of the downlink signal, downlink channel, and system information block of the first cell at the later of the first and second time points.

[0209] The first moment is a moment after the reference point, and the second moment is a moment after receiving the first uplink signal feedback.

[0210] In one implementation, the reference point can be the start or end time slot of the receiving window for the first uplink signal feedback. For example, the reference point can be the start or end time slot of the RAR receiving window of UL-WUS.

[0211] The above method starts listening at the later of the first and second moments, which can ensure the successful decoding of the first uplink signal feedback and avoid the situation where the terminal starts listening before successfully receiving the first uplink signal feedback. This can prevent the terminal from wasting power due to premature listening and save the terminal's power.

[0212] S306: The terminal stops listening to at least one of the downlink signals, downlink channels, and system information blocks of the first cell at the end of the first time window.

[0213] In this embodiment, the first time window refers to a time window used for receiving at least one of the downlink signal, downlink channel, and system information block of the first cell. The start time of the first time window may include one of the following:

[0214] 1) The first moment;

[0215] 2) Second moment;

[0216] 3) The later of the first and second time points;

[0217] 4) The earlier of the first and second moments.

[0218] In this embodiment, the duration of the first time window can be predefined by the protocol, indicated by the configuration of the first uplink signal, or indicated by feedback from the first uplink signal. The duration of the first time window can include one or more time units. The end time of the first time window can be determined based on its start time and duration.

[0219] For example, if the start time of the first time window is t1 and the duration of the first time window is configured by WUS to be 3 time units, then the end time of the first time window is t2, which is the end time of the 3 time units after t1. Therefore, the terminal can stop listening to at least one of the downlink signals, downlink channels and system information blocks of the first cell at time t2.

[0220] In this embodiment, the terminal may receive the first uplink signal feedback before the start of the first time window, or it may receive the first uplink signal feedback after the start of the first time window; the specific timing is not limited. Regardless of the scenario, the terminal can begin monitoring at least one of the downlink signal, downlink channel, and system information block of the first cell at the later of the first and second time windows, and cease monitoring at least one of the downlink signal, downlink channel, and system information block of the first cell at the end of the first time window. Examples are provided below with reference to the accompanying drawings.

[0221] Figure 4 is a schematic diagram of a scenario of the listening window provided in an embodiment of this application. Referring to Figure 4, the terminal sends a UL-WUS request OD-SIB1 and receives the RAR before the start time of the first time window. The reference point is the starting time slot of the RAR receiving window. The first time is the Xth time unit after the reference point. The second time is the Oth time unit after receiving the RAR. As shown in the figure, the second time is later than the first time, so the terminal starts listening to the Type 0 PDCCH of OD-SIB1 at the second time and stops listening to the Type 0 PDCCH at the end time of the first time window.

[0222] Figure 5 is a schematic diagram of another scenario of the listening window provided in the embodiments of this application. Referring to Figure 5, the terminal sends a UL-WUS request OD-SIB1 and receives the RAR before the start time of the first time window. The reference point is the starting time slot of the RAR receiving window. The first time is the Xth time unit after the reference point. The second time is the Oth time unit after receiving the RAR. As shown in the figure, the first time is later than the second time, so the terminal starts listening to the Type 0 PDCCH of OD-SIB1 at the first time and stops listening to the Type 0 PDCCH at the end time of the first time window.

[0223] Figure 6 is a schematic diagram of another scenario of the listening window provided in the embodiments of this application. Referring to Figure 6, the terminal sends a UL-WUS request OD-SIB1 and receives the RAR after the start time of the first time window. The reference point is the start time slot of the RAR receiving window. The first time is the Xth time unit after the reference point. The second time is the Oth time unit after receiving the RAR. As shown in the figure, the second time is later than the first time, so the terminal starts listening to the Type 0 PDCCH of OD-SIB1 at the second time and stops listening to the Type 0 PDCCH at the end time of the first time window.

[0224] Figure 7 is a schematic diagram of another scenario of the listening window provided in the embodiments of this application. Referring to Figure 7, the terminal sends a UL-WUS request OD-SIB1 and receives the RAR before the start time of the first time window. The reference point is the start time slot of the RAR receiving window. The first time is the time when the first timer started at the reference point times out (the duration of the first timer is Y time units). The second time is the time when the second timer started at the moment of receiving the RAR times out (the duration of the second timer is P time units). As can be seen from the figure, the second time is later than the first time, so the terminal starts listening to the Type 0 PDCCH of OD-SIB1 at the second time, and the terminal stops listening to the Type 0 PDCCH at the end time of the first time window.

[0225] Of course, in other implementations, the terminal may also choose to start listening to the Type 0 PDCCH of OD-SIB1 (not shown in the figure) at the first moment (when the first timer counts for more than Y time units), or it may choose to start listening to the Type 0 PDCCH of OD-SIB1 (not shown in the figure) at the second moment (when the second timer counts for more than P time units), and there is no specific limitation.

[0226] Figures 4 through 7 above are illustrated using the starting time slot of the RAR receiving window as the reference point. The following illustration uses the ending time slot of the RAR receiving window as the reference point.

[0227] Figure 8 is a schematic diagram of another scenario of the listening window provided in the embodiments of this application. Referring to Figure 8, the terminal sends a UL-WUS request OD-SIB1 and receives the RAR before the start time of the first time window. The reference point is the end gap of the RAR receiving window. The first time is the Xth time unit after the reference point. The terminal can start listening to the Type 0 PDCCH of OD-SIB1 at the first time and stop listening to the Type 0 PDCCH at the end time of the first time window.

[0228] The following section, in conjunction with Table 1, will explain in detail the definition and function of each target parameter in the target parameter set included in the configuration of the first uplink signal.

[0229] Table 1

[0230] Here, "conditionally present" means that the parameter is only used if the usage conditions are met. The rightmost column of the table describes how, if the corresponding parameter is not configured, the parameter value in the cell providing the first uplink signal will be used. An example is given below.

[0231] If the WUS configuration does not contain the physical cell identifier PhysCellIdList, then the NES cell to which the WUS configuration applies is the NES cell itself that provided the WUS configuration.

[0232] If PhysCellIdList is configured in the WUS configuration but the absolute radio frequency channel number ARFCN-ValueNR is not configured, the UE will use the center frequency of the SSB of the cell that provides the WUS configuration.

[0233] If PhysCellIdList is configured in the WUS configuration but frequencyBandList is not configured, the terminal will use the frequencyBandList in the uplink frequency information FrequencyInfoUL-SIB of the cell that provides the WUS configuration.

[0234] If PhysCellIdList is configured in the WUS configuration but the uplink subcarrier spacing ULSubCarrierSpacing is not configured, the terminal uses the uplink initial BWP (initial Uplink BWP of SIB) of the cell that provides the WUS configuration.

[0235] If PhysCellIdLis is configured in the WUS configuration but the SIB1 request period sib1-RequestPeriod is not configured, the terminal will use si-RequestPeriod in SI-RequestConfig of the cell that provides the WUS configuration.

[0236] If PhysCellIdList is configured in the WUS configuration, but the number of SSBs associated with each RO (ssb-perRACH-Occasion) is not configured, the terminal uses the number of SSBs associated with each RO of the cell that provides the WUS configuration (RACH-ConfigGeneric of SIB1).

[0237] Whether the WUS configuration includes PhysCellIdList can also be described as whether the WUS configuration indicates the cell identifier. For example, if the WUS configuration does not indicate the physical cell identifier PhysCellIdList, then the NES cell to which this WUS configuration applies is the NES cell itself that provided the WUS configuration. For example, if the WUS configuration indicates the physical cell identifier PhysCellIdList (which can be one or more cell identifiers), but does not configure frequencyBandList, then the UE uses the value of frequencyBandList in FrequencyInfoUL-SIB of the SIB1 of the cell that provided the WUS configuration.

[0238] For details on the usage of other parameters, please refer to the notes in Table 1 above. They will not be repeated here.

[0239] In this embodiment of the application, the terminal may determine the uplink frequency point A (UL point A) in the following manner:

[0240] The first method: For Frequency Division Duplex (FDD) systems, the terminal can determine UL point A based on absoluteFrequencyPointA in the WUS configuration. If absoluteFrequencyPointA is not configured in the WUS configuration, the terminal can determine UL point A based on absoluteFrequencyPointA in the cell providing the WUS configuration. Alternatively, the terminal can also determine UL point A based on ssb-SubcarrierOffset and offsetToPointA in the cell providing the WUS configuration.

[0241] The second method: For Time Division Duplex (TDD) systems, the terminal can determine DL point A based on ssb-SubcarrierOffset and offsetToPointA in the WUS configuration. Since UL pointA and DL pointA are consistent in the TDD system, the terminal determines UL point A based on ssb-SubcarrierOffset and offsetToPointA.

[0242] If the WUS configuration does not include ssb-SubcarrierOffset, the terminal can determine DL pointA and then UL pointA based on the ssb-SubcarrierOffset of the cell providing the WUS configuration and offsetToPointA in the WUS configuration.

[0243] If the WUS configuration does not include offsetToPointA, the terminal can determine DL pointA and then UL pointA based on offsetToPointA in SIB1 of the cell providing the WUS configuration and ssb-SubcarrierOffset in the WUS configuration.

[0244] If the WUS configuration does not include ssb-SubcarrierOffset and offsetToPointA, the terminal can determine DL pointA and then UL pointA based on the ssb-SubcarrierOffset and offsetToPointA of the cell that provides the WUS configuration.

[0245] If the WUS configuration does not include ssb-SubcarrierOffset and offsetToPointA, the terminal can also determine UL pointA based on absoluteFquencyPointA in FrequencyInfoUL-SIB of the cell that provides the WUS configuration.

[0296] In this embodiment of the application, if the configuration of the first uplink signal does not include the target parameter, the terminal uses the value of the corresponding parameter in the cell that provides the configuration of the first uplink signal.

The first uplink signal is used to request the transmission of at least one of the downlink signal, downlink channel, and system information block of a first cell. The network-side device transmits the first uplink signal back to the terminal and transmits at least one of the downlink signal, downlink channel, and system information block of the first cell to the terminal. This provides a solution for the network-side device to transmit at least one of the downlink signal, downlink channel, and system information block.

[0321] Figure 10 is a flowchart illustrating a method for obtaining uplink signal configuration provided in an embodiment of this application. This method 1000 can be executed by a terminal. As shown in Figure 10, the method may include the following steps.

[0322] S1002: The terminal is configured to acquire the first uplink signal in the third cell, wherein the first uplink signal is used to trigger the transmission of downlink signals or system information in the fourth cell.

[0323] In some embodiments, the third cell and the fourth cell can be the same cell, that is, the cell in which the UE obtains the WUS configuration is the same cell as the cell in which the UE requests SIB1 to send.

[0324] In some embodiments, the UE obtains WUS configuration in the NES cell and sends a UL-WUS request to the NES cell for SIB1 transmission. In this embodiment, the NES cell is both the third cell and the fourth cell.

[0325] In some embodiments, the third cell and the fourth cell are different cells; the third cell is a non-energy-efficient cell, and the fourth cell is an energy-efficient cell. The first uplink signal is UL-WUS. The UE obtains WUS configuration in the non-energy-efficient cell, and UL-WUS is used to request SIB1 transmission in the energy-efficient cell.

[0326] In some embodiments, the third cell is the cell where the UE is currently camped, the fourth cell is an energy-saving cell, and the first uplink signal is UL-WUS. After the UE camps on an NES cell, it obtains the WUS configuration of the camped cell. When the camped cell becomes an energy-saving cell, it can use this configuration to request SIB1 transmission from the currently camped cell.

[0327] In some embodiments, the third cell is a cell that periodically transmits SIB1, and the fourth cell is a cell that non-periodically transmits SIB1.

[0328] In some embodiments, the third cell is a cell that periodically transmits SIB1, and the fourth cell is a cell that allows on-demand requests for SIB1 transmission.

[0329] In this embodiment of the application, after the terminal obtains the configuration of the first uplink signal in the third cell, it further includes:

[0330] Based on the configuration of the first uplink signal, the terminal determines that the fourth cell is the third cell.

[0331] In this embodiment of the application, the terminal determines the fourth cell as the third cell based on the configuration of the first uplink signal, including at least one of the following:

[0332] If the third information field is not configured in the configuration of the first uplink signal, the terminal determines the fourth cell as the third cell;

[0333] If the fourth information field in the configuration of the first uplink signal is consistent with the third cell, the terminal determines that the fourth cell is the third cell;

[0334] If the fifth information field in the configuration of the first uplink signal indicates that the configuration of the first uplink signal applies to the third cell, the terminal determines the fourth cell as the third cell.

[0335] In this embodiment of the application, the third information field or the fourth information field includes at least one of the following:

[0336] 1) Physical Cell Identifier (PhysCellId);

[0337] 2) Physical Cell Identifier List (PhysCellIdList);

[0338] 3) Absolute radio frequency channel number ARFCN-ValueNR.

[0339] In some embodiments, the first uplink signal is WUS, an uplink wake-up signal, used to request the transmission of system information blocks for the energy-saving cell.

[0340] In some embodiments, the first uplink signal is configured as a WUS configuration, which includes various parameters required for UL-WUS transmission.

[0341] In some embodiments, the UE determines whether the cell to which the WUS configuration applies (i.e., the fourth cell, i.e., the cell triggered by UL-WUS) is the cell (the third cell) to which the UE obtains the WUS configuration based on the following three methods:

[0342] Method 1: If PhysCellId or PhysCellIdList is not configured in the WUS configuration, the UE assumes / determines that the fourth cell is the third cell.

[0343] Method 2: If the PhysCellId in the WUS configuration is the same as the PhysCellId of the third cell, and the ARFCN-ValueNR in the WUS configuration is the same as the ARFCN-ValueNR of the third cell, then the UE assumes / determines that the fourth cell is the third cell.

[0344] Method 3: If the information field in the WUS configuration directly indicates that the WUS configuration applies to this cell (third cell), then the UE assumes / determines that the fourth cell is the third cell.

[0345] In this embodiment of the application, when the terminal determines that the fourth cell is the third cell, some target parameters in the target parameter set included in the configuration of the first uplink signal do not exist;

[0346] Alternatively, if the terminal determines that the fourth cell is the third cell, the terminal determines a portion of the target parameter values ​​in the target parameter set included in the configuration of the first uplink signal based on the target parameter values ​​of the third cell.

[0347] In this embodiment of the application, if the target parameter is not included in the target parameter set included in the configuration of the first uplink signal, the terminal uses the value of the corresponding parameter in the third cell system information to determine the value of the target parameter.

[0348] In some embodiments, if the fourth cell is determined to be the third cell, some target parameters in the target parameter set of the first uplink signal configuration are not present. For example, the target parameters include at least one of the following: PhysCellIdList, ARFCN-ValueNR, frequencyBandList, absoluteFrequencyPointA, offsetToPointA, offsetToCarrier, p-Max, ULSubCarrierSpacing, rsrp-ThresholdSSB, prach-RootSequenceIndex, msg1-SubcarrierSpacing, restrictedSetConfig, ss-PBCH-BlockPower, ssb-PositionsInBurst, tdd-UL-DL-ConfigurationCommon.

[0349] In some embodiments, if the fourth cell is determined to be the third cell, some target parameters in the target parameter set of the first uplink signal configuration do not exist, and the UE determines the value of the non-existent target parameter based on the corresponding value in the third cell.

[0350] In some embodiments, if the WUS configuration does not include a target parameter, the UE determines the value of the target parameter based on the corresponding parameter value in the cell where the WUS configuration is obtained.

[0391] The fifth information field is used to indicate that the configuration of the first uplink signal is applicable to the third cell.

[0392] The following section, in conjunction with Table 2, will explain in detail the definition and function of each target parameter in the target parameter set included in the configuration of the first uplink signal.

[0393] Table 2

[0394] Here, "conditionally present" means that the parameter is only used if the usage conditions are met. The rightmost column of the table describes how, if the corresponding parameter is not configured, the parameter value in the cell providing the first uplink signal will be used. An example is given below.

[0395] If the WUS configuration does not contain the physical cell identifier PhysCellIdList, then the NES cell to which the WUS configuration applies is the NES cell itself that provided the WUS configuration.

[0396] If PhysCellIdList is configured in the WUS configuration but the absolute radio frequency channel number ARFCN-ValueNR is not configured, the UE will use the center frequency of the SSB of the cell that provides the WUS configuration.

[0397] If PhysCellIdList is configured in the WUS configuration but frequencyBandList is not configured, the terminal will use the frequencyBandList in the uplink frequency information FrequencyInfoUL-SIB of the cell that provides the WUS configuration.

[0398] If PhysCellIdList is configured in the WUS configuration but the uplink subcarrier spacing ULSubCarrierSpacing is not configured, the terminal uses the uplink initial BWP (initial Uplink BWP of SIB) of the cell that provides the WUS configuration.

[0399] If PhysCellIdLis is configured in the WUS configuration but the SIB1 request period sib1-RequestPeriod is not configured, the terminal will use si-RequestPeriod in SI-RequestConfig of the cell that provides the WUS configuration.

[0400] If PhysCellIdList is configured in the WUS configuration, but the number of SSBs associated with each RO (ssb-perRACH-Occasion) is not configured, the terminal uses the number of SSBs associated with each RO of the cell that provides the WUS configuration (RACH-ConfigGeneric of SIB1).

[0401] Whether the WUS configuration includes PhysCellIdList can also be described as whether the WUS configuration indicates the cell identifier. For example, if the WUS configuration does not indicate the physical cell identifier PhysCellIdList, then the NES cell to which this WUS configuration applies is the NES cell itself that provided the WUS configuration. For example, if the WUS configuration indicates the physical cell identifier PhysCellIdList (which can be one or more cell identifiers), but does not configure frequencyBandList, then the UE uses the value of frequencyBandList in FrequencyInfoUL-SIB of the SIB1 of the cell that provided the WUS configuration.

[0402] For details on the usage of other parameters, please refer to the notes in Table 2 above. They will not be repeated here.

[0403] In this embodiment of the application, the terminal may determine the uplink frequency point A (UL point A) in the following manner:

[0404] The first method: For Frequency Division Duplex (FDD) systems, the terminal can determine UL point A based on absoluteFrequencyPointA in the WUS configuration. If absoluteFrequencyPointA is not configured in the WUS configuration, the terminal can determine UL point A based on absoluteFrequencyPointA in the cell providing the WUS configuration. Alternatively, the terminal can also determine UL point A based on ssb-SubcarrierOffset and offsetToPointA in the cell providing the WUS configuration.

[0405] The second method: For Time Division Duplex (TDD) systems, the terminal can determine DL point A based on ssb-SubcarrierOffset and offsetToPointA in the WUS configuration. Since UL pointA and DL pointA are consistent in the TDD system, the terminal determines UL point A based on ssb-SubcarrierOffset and offsetToPointA.

[0406] If the WUS configuration does not include ssb-SubcarrierOffset, the terminal can determine DL pointA and then UL pointA based on the ssb-SubcarrierOffset of the cell providing the WUS configuration and offsetToPointA in the WUS configuration.

[0407] If the WUS configuration does not include offsetToPointA, the terminal can determine DL pointA and then UL pointA based on offsetToPointA in SIB1 of the cell providing the WUS configuration and ssb-SubcarrierOffset in the WUS configuration.

[0408] If the WUS configuration does not include ssb-SubcarrierOffset and offsetToPointA, the terminal can determine DL pointA and then UL pointA based on the ssb-SubcarrierOffset and offsetToPointA of the cell that provides the WUS configuration.

[0409] If the WUS configuration does not include ssb-SubcarrierOffset and offsetToPointA, the terminal can also determine UL pointA based on absoluteFquencyPointA in FrequencyInfoUL-SIB of the cell that provides the WUS configuration.

[0410] The method for obtaining uplink signal configuration provided in this application embodiment involves the terminal obtaining the configuration of the first uplink signal in the third cell. The first uplink signal is used to trigger the transmission of downlink signals or system information in the fourth cell. The configuration of the first uplink signal has been optimized, which can reduce the overhead of the network side transmitting the configuration of the first uplink signal.
