[0002] The present disclosure is based on and claims the priority of Chinese patent application with application number 202410405664X and application date April 3, 2024. The entire contents of the Chinese patent application are hereby introduced into the present disclosure in their entirety. Technical Field

[0003] The present disclosure relates to the field of wireless communication technologies, and in particular to an information transmission method, apparatus, device, storage medium, and computer program product. Background Art

[0004] Currently, network energy saving is an important means to reduce operator expenses and achieve low-carbon green 5G development. Network energy saving methods include time domain, frequency domain, power domain, and spatial domain. Currently, the focus is on energy saving when the network serves connected users. For example, in order to increase the shutdown opportunities in the time domain, the cell discontinuous transmission (DTX) or discontinuous reception (DRX) mechanism is introduced. In the frequency domain, SSB-less secondary cells (Scells) are introduced so that the base station can have more time to shut down the Scell ​​to achieve energy saving. In the spatial domain, adaptive antenna array shutdown is introduced. In the power domain, adaptive PDSCH transmission power adjustment is introduced to achieve network energy saving. However, in the above energy saving solutions, there is no adaptive adjustment of the configuration of signals or channels sent in broadcast form, such as synchronization signal blocks (SSBs), physical random access channels (PRACHs), and paging. Therefore, there is an urgent need to provide a technical solution that can adaptively indicate the configuration of SSBs, PRACHs, and paging. Summary of the Invention

[0126] Before introducing the technical solutions of the embodiments of the present disclosure, the relevant technologies are first introduced.

[0127] In related technologies, network energy conservation is an important means to reduce operators' operating expenses (OPEX) and achieve low-carbon, green 5G development. Network energy conservation methods include time domain, frequency domain, power domain, and spatial domain. Currently, the focus is on energy conservation when the network serves connected users. For example, to increase the shutdown opportunities in the time domain, a cell discontinuous transmission (DTX) or discontinuous reception (DRX) mechanism is introduced. The network can periodically enter an inactive period, during which the transmission of periodic / semi-persistent reference signals, such as the channel state information reference signal (CSI-RS), is reduced, thereby reducing the base station's transmission power consumption. The user equipment (UE) no longer sends periodic CSI reports or periodic / semi-persistent sounding reference signals (SRS), thereby reducing the base station's receiving power consumption. New data scheduling is no longer performed, and the transmission and reception of the semi-persistently scheduled physical downlink shared channel (SPS-PDSCH) and the configured authorized physical uplink shared channel (CG-PUSCH) are stopped. Introducing SSB-less secondary cells (Scells) in the frequency domain allows base stations to more frequently shut down Scells, achieving energy savings. Adaptive antenna array shutdown in the spatial domain and adaptive PDSCH transmit power adjustment in the power domain can both contribute to network energy savings.

[0128] However, in order to reduce the impact on UEs in idle or inactive states, the above energy-saving solution does not perform adaptive adjustment on the configuration of signals or channels sent in broadcast form, such as SSB, SIB1, PRACH, and paging.

[0129] Specifically, it may include:

[0130] First, considering that even when a cell has no user services, it still needs to send periodic broadcast signals, which prevents the base station from entering a deep sleep state and affects its energy efficiency. To this end, further research will be conducted on the adaptability of broadcast signals. One of the most direct energy-saving methods is to reduce the transmission period of SSB and SIB1 signals, sending them more sparsely and increasing the time interval between two consecutive transmissions. This will allow the network to enter a deeper sleep state.

[0131] Second, for PRACH, when the network configures PRACH resources, the network needs to always detect PRACH regardless of whether there is a UE sending PRACH, which will also increase the power consumption of the base station.

[0132] Third, for paging messages, due to the existing paging configuration, the paging timing of users in the cell is dispersed as evenly as possible within the DRX cycle. As a result, when the base station sends a paging message, especially for paging message updates or short messages, it is necessary to send relevant information in each paging frame. As a result, messages need to be sent at even intervals throughout the DRX cycle, and it is impossible to enter deep sleep for a long time, resulting in high power consumption of the base station.

[0133] Regarding how the aforementioned broadcast signals or channels can be adapted to achieve energy conservation in base stations, related technologies propose methods such as reducing SSB transmission density for SSB transmission adaptation, introducing two PRACH configurations, with the second PRACH adaptively transmitted on demand, and introducing a compact paging configuration, centralizing paging transmission within a DRX cycle rather than distributing it evenly. However, it is important to consider that the adaptation of these broadcast signals or channels will affect idle and inactive terminals. Since these terminals are not connected to a cell, they cannot receive terminal-specific control information and RRC messages indicating the adaptation of these broadcast signals or channels.

[0134] In the related art, it is proposed to use paging DCI to indicate the adaptation of common signals. However, one problem with using paging messages is that since they need to be broadcast to all terminals, once adaptation occurs, even if there is no need to send a paging message to the terminal, the network needs to send paging DCI on each paging occasion (PO), resulting in large network overhead.

[0135] Based on this, in an embodiment of the present disclosure, the network device sends downlink control information (DCI) to the terminal; wherein the DCI is used for at least one of the following: indicating the transmission configuration of the synchronization signal block (SSB); indicating the configuration of the physical random access channel (PRACH); indicating the paging-related configuration.

[0136] Referring to FIG. 1 , FIG. 1 is a schematic diagram of an implementation flow of an information transmission method according to an embodiment of the present disclosure, which is applied to a network device. As shown in FIG. 1 , the method includes step 101:

[0137] Step 101: Send DCI to the terminal;

[0138] The DCI is used for at least one of the following:

[0139] Indicates the transmission configuration of SSB;

[0140] Indicates the configuration of PRACH;

[0141] Indicates paging-related configuration.

[0142] Here, the DCI indicates the transmission configuration of the SSB, which can also be understood as the transmission configuration of the SSB being switched or changed from one configuration to another, and the indicated configuration is the configuration that takes effect subsequently.

[0143] Here, the DCI indicates the configuration of the PRACH, which can also be understood as the configuration of the PRACH being switched or changed from one configuration to another, and the indicated configuration is the configuration that takes effect subsequently.

[0144] Here, the DCI indicates a paging-related configuration, which can also be understood as a switch or change in the paging-related configuration, from one configuration to another, and the indicated configuration is the configuration that takes effect subsequently.

[0145] In some embodiments, the DCI is a DCI scrambled by a cyclic redundancy check (CRC) using a system information radio network temporary identifier (SI-RNTI).

[0146] Here, the DCI with SI-RNTI scrambled CRC can be used to schedule the transmission of system information such as SIB1.

[0147] Among them, SIB1 is transmitted on the downlink shared channel (DL-SCH) with a period of 160ms and a variable transmission repetition period within 160ms. The default transmission repetition period of SIB1 is 20ms, but the actual transmission repetition period depends on the network implementation. For the synchronization signal block (SSB) and control resource set (CORESET) multiplexing mode 1, the SIB1 repetition transmission period is 20ms. For SSB and CORESET multiplexing modes 2 / 3, the SIB1 transmission repetition period is the same as the SSB period. SIB1 includes information about the availability and scheduling of other SIBs (for example, mapping of SIBs to SI messages, periodicity, SI window size), and an indication of whether one or more SIBs are provided only on demand, and in this case, the configuration required for the user equipment (UE) to perform the system information (SI) request. SIB1 is a cell-specific SIB. For convenience of description, the times when SIB1 is transmitted are called SIB1 transmission times, abbreviated as SO.

[0148] The following is the information field included in the DCI of the scheduling SIB1 message. The DCI format is DCI 1_0, and the DCI is the DCI scrambled by SI-RNTI CRC:

[0149] Frequency domain resource allocation, occupation bits; among them, It indicates the size of CORESET 0 in the downlink (DL) bandwidth part (BWP, BandWidth Part), that is, the number of RBs;

[0150] Time domain resource allocation, occupies 4 bits;

[0151] The mapping of virtual resource blocks (VRBs) to physical resource blocks (PRBs) occupies 1 bit;

[0152] Modulation and coding scheme, occupies 5 bits;

[0153] Redundant version, occupies 2 bits;

[0154] System information indication, occupies 1 bit;

[0155] Reserved bit, occupies 17 bits, used for operation in a cell with shared spectrum channel access, otherwise it is 15 bits.

[0156] It can be seen from the above content that 17 bits are reserved in the case of shared spectrum access, and 15 bits are reserved otherwise, so the above indication information can be carried by the reserved bits.

[0157] The following details the implementation process of adaptive indication SSB configuration, PRACH configuration, and paging configuration.

[0158] In the first case, the network device adaptively indicates the SSB configuration through DCI.

[0159] In some embodiments, the indicating the transmission configuration of the SSB includes:

[0160] Indicates that the transmission configuration of the SSB is one SSB configuration among at least two SSB configurations configured in the network device.

[0161] Here, the network device may configure the at least two SSB configurations for the terminal through system information such as SIB1 message. Because idle / inactive terminals cannot receive user-specific indication information, idle / inactive terminals can obtain the configuration through broadcast system information.

[0162] Here, the SSB may include a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast channel (PBCH).

[0163] Here, the transmission configuration indicating SSB is one of the at least two SSB configurations configured in the network device, which can also be understood as the transmission configuration of SSB being switched, that is, being switched to one of the at least two SSB configurations configured in the network device.

[0164] In some embodiments, the transmission configuration indicating the SSB is one of the at least two SSB configurations configured by the network device, including:

[0165] Indicates that the transmission period of the SSB is one SSB period of at least two SSB periods configured for the network device.

[0166] Here, the transmission period of the indicated SSB is one of the at least two SSB periods configured by the network device. It can also be understood that the transmission period of the SSB has been switched, that is, it is switched to one of the at least two SSB periods configured by the network device.

[0167] Here, the network device may configure N SSB transmission periods for the terminal through system information such as a SIB1 message, where N is an integer greater than or equal to 2. For example, the SSB transmission period may be configured as {5ms, 10ms, 20ms, 40ms, 80ms, 160ms}.

[0168] Here, the network device can adaptively adjust the transmission configuration of SSB according to the energy-saving status of the network device, the user's measurement requirements, etc., and realize adaptive switching of SSB through the DCI indication.

[0169] Specifically, when the network device, such as a base station, is in an energy-saving state, the network device can adjust the transmission period of the SSB indicated by the DCI to a larger period, that is, the transmission period of the SSB has been switched. When the period of the SSB is larger, the interval between two adjacent SSBs sent by the network device is larger, so that there is a larger interval without waking up to send the SSB, and there is a chance to enter a deeper sleep, thereby achieving energy saving on the network side, such as the base station. When there are users in the network who need to measure with a smaller SSB period, the network device can adjust the transmission period of the SSB indicated by the DCI to a smaller period, that is, the transmission period of the SSB has been switched, thereby achieving self-adaptation of the SSB period, and the self-adaptation is achieved by the period of the SSB indicated by the DCI being one of the N SSB periods configured by the network device.

[0170] Here, the adaptive switching of the SSB cycle is applicable to terminals in a connected state, and is also applicable to terminals in an idle state or an inactive state.

[0171] This is because the SSB is the information that a terminal must first identify when accessing a cell. Only by reading the information in the PBCH contained in the SSB can the time-frequency resource location of the type 0 physical downlink control channel (type 0-PDCCH, type 0-Physical Downlink Control Channel) be obtained, thereby obtaining the SIB1 scheduling information. Therefore, if you want to obtain the SSB configuration through the SIB1 message, for cells that are independently accessible to idle or inactive terminals, the terminal needs to search for the synchronization signal for a longer time. After detecting the SSB, it must obtain the corresponding SIB1 to know the SSB transmission period information of the current cell.

[0172] In the second case, the PRACH configuration is adaptively indicated through DCI.

[0173] In some embodiments, the configuration indicating the PRACH includes at least one of the following:

[0174] Indicates whether the PRACH configuration is enabled;

[0175] Indicate that the configuration index of the PRACH is one of the at least two PRACH configuration indexes configured by the network device;

[0176] Indicate that the PRACH period is one of at least two PRACH periods configured by the network device;

[0177] Indicates the validity or activation status of the PRACH association period of the PRACH;

[0178] Indicates the validity or activation status of the PRACH associated mode period of the PRACH.

[0179] Here, the network device may configure an independent PRACH configuration for a terminal supporting Network Energy Saving (NES). Accordingly, the indication of whether the PRACH configuration is enabled may mean that when an independent PRACH configuration is configured for a terminal or user supporting Network Energy Saving (NES), the DCI may indicate whether the independent PRACH configuration is enabled. When not enabled, it means that users supporting NES use the same PRACH configuration as other non-energy-saving users, such as a relatively sparse PRACH configuration; when enabled, NES users use the independently configured PRACH configuration to meet the more random access requirements of users supporting NES.

[0180] Here, when a terminal or user supporting Energy Saving (NES) has multiple PRACH configurations available, the DCI may indicate which PRACH configuration is in effect.

[0181] Here, different PRACH configurations may have different indexes. For example, different PRACH configuration indexes are configured in a higher layer parameter such as RACH-ConfigGeneric, and the DCI may indicate which PRACH configuration index to use.

[0182] Here, as shown in Table 1, a terminal such as a UE can correspond to the preamble format, the system frame for sending PRACH (satisfying nSFNmodx=y, where nSFN represents the radio frame where the PRACH period is located, x represents the PRACH period, and y represents the position of the radio frame where the PRACH resource is located within the PRACH period), subframe position, start symbol, number of PRACH time slots in the subframe, number of PRACH opportunities in a PRACH time slot, and PRACH duration and other parameters through the PRACH configuration index (Configuration Index).

[0183] Table 1

[0184] Here, when the PRACH configuration provided by the network device for a terminal or user supporting network energy saving includes M period configurations, where M>1, i.e., M is an integer greater than 1, the DCI may indicate the PRACH period to be effective. For example, if the configured PRACH period includes 40ms and 80ms, the DCI indicates switching to the PRACH period corresponding to 80ms.

[0185] Here, the PRACH period may be adaptively adjusted according to the energy-saving state of the network device, the number of randomly accessed users, etc., and indicated through the DCI to achieve adaptive switching of the PRACH period.

[0186] Specifically, when the network device, such as a base station, is in an energy-saving state, the network device can adjust the PRACH period indicated by the DCI to a sparser period. By configuring a sparser period, or configuring fewer PRACH transmission opportunities within the same period, the frequency of the base station monitoring the PRACH can be reduced, thereby achieving energy saving of the base station. When the number of users who need to perform random access in the network increases, and a small amount of PRACH resources cannot meet the user access requirements, resulting in an increased probability of access collision, the network device needs to switch to a denser PRACH period, or switch to a configuration with more PRACH transmission opportunities. At this time, the network energy saving effect is poor, but the user experience is better, thereby achieving self-adaptation of the PRACH period. The self-adaptation is implemented by the DCI indicating that the PRACH period is one of the N PRACH periods configured by the network device. That is, the switching of the PRACH configuration is indicated by the indication information to achieve PRACH adaptation.

[0187] Here, for the PRACH resources in the time domain, the following three periods are defined:

[0188] The PRACH configuration period (or PRACH period) refers to the repetition period of the random access channel opportunity (RO) occurring in the time domain before considering validity and SSB association, corresponding to x in Table 1 above.

[0189] The PRACH association period refers to a time length with a value range of {10, 20, 40, 80, 160}, which can ensure that each SSB actually sent is mapped to a valid random access channel opportunity (RO) at least once, and has a minimum value.

[0190] The PRACH association period may start from radio frame 0 (frame 0), and the period is an integer multiple of the PRACH configuration period, such as 1, 2, 4, 8, 16 times, but not greater than 160ms.

[0191] A PRACH association pattern period includes one or more PRACH association periods. The mapping of SSBs to ROs within each association pattern period is repeated. Since the number of valid ROs may vary in different PRACH association periods, the mapping within each association pattern period is repeated by including one or more PRACH association periods.

[0192] Refer to FIG2 , which is a schematic diagram showing the relationship among a PRACH configuration period, a PRACH association period, and a PRACH association mode period.

[0193] Table 2 is the mapping relationship between the PRACH configuration period and the SSB to PRACH association period. As shown in Table 2, a PRACH association period, starting from frame 0, is used to map the SSB index to the PRACH opportunity (Occasion) association period. It is the minimum value in the set determined by the PRACH configuration period according to Table 2, so that The SSB index is mapped to the PRACH occasion at least once in the associated period, where the UE obtains the value of ssb-PositionInBurst from SIB1 or ServingCellConfigCommon If an integer number of SSB indices are mapped to PRACH opportunities within the associated period, there is a group of PRACH opportunities that are not mapped. If there are an integer number of SSB indices, it means that no SSB index is mapped to the set of PRACH opportunities. The association pattern period includes one or more association periods and is determined so that the mapping pattern between PRACH opportunities and SSB block indices is repeated at most once every 160 milliseconds, and after an integer number of association periods (if any), the PRACH opportunity is not associated with an SSB index and is not used for PRACH transmission.

[0194] Table 2

[0195] In some embodiments, the indication of the validity or activation status of the PRACH association period of the PRACH includes:

[0196] Indicates the validity or activation status of each M PRACH associated period; where M is an integer greater than 1.

[0197] In some embodiments, the indicating the validity or activation status of each M PRACH associated period includes:

[0198] Whether each PRACH associated period in each of the M PRACH associated periods is valid or activated is indicated in a bitmap manner.

[0199] Here, whether the function is effective or activated may also be described as whether the function can be used to transmit the PRACH.

[0200] Here, if you want to achieve energy saving at the PRACH association period level, you can configure a first time length T PAP , the first time length T PAPIt is an integer multiple of the PRACH association period, assuming it is M times, and then each first time length T is indicated by an Mbit bitmap PAP The validity status or activation status of M PRACH association periods within the period.

[0201] For example, M is equal to 2, the first bit represents the first PRACH association period, and the second bit represents the second PRACH association period. When the first bit is 0, it means that PRACH transmission cannot be performed in the PRACH association period corresponding to the first bit, so that network equipment such as base stations do not need to monitor in the corresponding PRACH association period, saving PRACH monitoring power consumption in the corresponding period. If the value of the first bit is 1, it means that the first PRACH association period is effective or activated. In this way, PRACH transmission can be performed in the first PRACH association period, so that the network equipment monitors in the PRACH association period.

[0202] Here, considering that the PRACH association period starts from radio frame 0 (frame0), the terminal such as UE can start from (SFN×10) mod T PAP =0 corresponds to the first bit in the M bits, the second PRACH association period corresponds to the second bit in the M bits, and so on, the Mth PRACH association period corresponds to the Mth bit in the M bits, where SFN represents the system frame number, T PAP It is an integer multiple of the PRACH association period. In this way, it is possible to determine which first PRACH association period corresponds to the first bit of the M bits based on the bit indication, determine the correspondence between the M bits and the PRACH association period, and determine whether the corresponding PRACH association period allows PRACH transmission based on the bit value.

[0203] In some embodiments, the indication of the validity or activation status of the PRACH associated mode period of the PRACH includes:

[0204] Indicates the validity or activation status of every L PRACH associated mode periods; where L is an integer greater than 1.

[0205] In some embodiments, the indicating the validity or activation status of each L PRACH associated mode period includes:

[0206] Whether each PRACH associated mode period in each L PRACH associated mode periods is valid or activated is indicated in a bitmap manner.

[0207] Here, whether the function is effective or activated may also be described as whether the function can be used to transmit the PRACH.

[0208] Here, for energy saving at the PRACH association pattern period level, a second time length T can also be defined. PAPP , the second time length T PAPP It is an integer multiple of the PRACH association pattern period, assuming it is L times, and then each second time length T is indicated by an L bit bitmap PAPP The validity status or activation of L PRACH association pattern periods within.

[0209] For example, L is equal to 2, the first bit represents the first PRACH association pattern period, and the second bit represents the second PRACH association pattern period. When the first bit is 0, it indicates that PRACH transmission cannot be performed in the corresponding PRACH association pattern period, so that network devices such as base stations do not need to monitor in the corresponding PRACH association pattern period, saving PRACH monitoring power consumption in the corresponding period. If the value of the first bit is 1, it indicates that the first PRACH association pattern period is effective or activated. In this way, PRACH transmission can be performed in this PRACH association pattern period, and the network device monitors in this PRACH association pattern period.

[0210] Here, considering that the PRACH association pattern period also starts from radio frame 0 (frame 0), the terminal such as UE can start from (SFN×10) mod T PAPP=0 corresponds to the first bit in the L bits, the second PRACH association pattern period corresponds to the second bit in the L bits, and so on, the Lth PRACH association pattern period corresponds to the Lth bit in the L bits, where SFN represents the system frame number, T PAPP It is an integer multiple of the PRACH association pattern period. In this way, it is possible to determine which first PRACH association pattern period corresponds to the first bit of the L bits according to the bit indication, determine the correspondence between the L bits and the PRACH association pattern period, and determine whether the corresponding PRACH association pattern period allows PRACH transmission according to the bit value.

[0211] In the third case, the paging configuration is adaptively indicated through DCI.

[0212] In some embodiments, the configuration indicating paging-related information includes at least one of the following:

[0213] Indicates whether the paging configuration is effective;

[0214] The paging configuration indicated to be in effect is one of the at least two paging configurations configured in the network device.

[0215] Here, the network device can configure a set of paging configurations for traditional terminals that do not support NES, and a set of special paging configurations for terminals that support NES. Accordingly, the indication of whether the paging configuration is effective can be understood as indicating whether the paging configuration corresponding to the terminal that supports NES is enabled to achieve adaptive paging configuration. When the paging configuration corresponding to the terminal that supports NES is not enabled, the network will transmit paging less frequently, and the paging capacity will also be smaller, but the network energy consumption can be lower. When the paging configuration corresponding to the terminal that supports NES is enabled, the capacity for accommodating paging becomes larger, but compared to switching to a similar traditional distributed paging configuration with a shorter adjacent PF (paging frame) interval, the network energy consumption is lower.

[0216] For example, when a dedicated paging configuration is configured for a Network Energy Saving (NES) terminal, the NES terminal can be instructed to use the dedicated paging configuration or a paging configuration dedicated to other non-NES terminals. For example, a "0" indication bit indicates the use of a paging configuration dedicated to other non-NES terminals, while a "1" indication bit indicates the use of a paging configuration dedicated to NES terminals.

[0217] Here, the paging configuration indicated to be effective is one of at least two network configurations, which can be understood as a paging configuration switch, that is, switching to one of the at least two paging configurations configured by the network device, that is, indicating which paging configuration to use subsequently.

[0218] Here, the network device may also configure two sets of paging configurations for the terminal supporting NES, one set supporting fewer paging occasions and the other set supporting more paging occasions, so as to adapt between the two sets. The configuration may be performed through SIB1 messages.

[0219] For example, the network device can configure at least two dedicated paging configurations for NES terminals, using an indication message to indicate which paging configuration to use after a certain application time. For example, a compact paging configuration 1 can be configured, where all paging opportunities are concentrated within a short window within the entire paging cycle, and a paging configuration 2 can be configured, similar to traditional paging, where paging opportunities are evenly distributed throughout the paging cycle. When the paging probability increases to a certain level, the device switches to paging configuration 2, which can accommodate more paging capacity.

[0220] Here, the principle of energy saving of paging is similar to that of PRACH, but it corresponds to the power consumption of network devices such as base stations when sending, while PRACH corresponds to the power consumption of network devices such as base stations when receiving.

[0221] In some embodiments, the sending of the DCI to the terminal includes:

[0222] The DCI is sent to the terminal at each transmission opportunity of the PDCCH carrying the DCI.

[0223] Here, the network device on the sending side may send the DCI carrying the above indication message to the terminal at each transmission opportunity of the PDCCH carrying the DCI.

[0224] Here, the receiving terminal can choose to Adapt The DCI may be received at a fixed transmission opportunity of the PDCCH carrying the DCI within the period, or at any transmission opportunity of the PDCCH carrying the DCI within the period.Adapt It should be a multiple of 20ms or 160ms.

[0225] It should be noted that in this way, the frequency of adaptive changes in SSB configuration, PRACH configuration, and paging configuration is allowed to be every T Adapt Supporting the change once has higher flexibility compared with the adaptive indication carried by paging DCI proposed in the related technical solutions.

[0226] In some embodiments, the sending of the DCI to the terminal includes:

[0227] Sending the DCI to the terminal according to a first period;

[0228] The first period is a multiple of the transmission period of SIB1 or a multiple of the transmission repetition period of SIB1.

[0229] Here, the network device on the sending side may periodically send the DCI carrying the above indication information, and the first period of sending the DCI is T Adapt , usually T Adapt It should be a multiple of 20ms or 160ms.

[0230] For example, only when (SFN×10) mod T Adapt =0, wherein SFN represents the system frame number, mod represents the modulus operation, and T Adapt Indicates that the DCI is sent in the first cycle or the nth transmission opportunity, where n is less than the maximum number of transmission opportunities in each first cycle. The corresponding receiving side also detects the indication information at the corresponding position to determine whether adaptive switching of the SSB configuration, PRACH configuration, and paging configuration occurs.

[0231] In some embodiments, different information bits in the DCI respectively indicate at least one of the following:

[0232] SSB configuration;

[0233] PRACH configuration;

[0234] Paging configuration.

[0235] Here, the adaptive indication of each signal or channel is independently indicated.

[0236] For example, assuming that the SSB includes 2 cycle switches, 1 bit is required; the PRACH may include whether to start, or even include starting configuration 1 or configuration 2, assuming that 2 bits are required. If the indication of the PRACH association period is considered, it is assumed that M bits are required, M=4; the adaptation of the paging configuration may include whether to start, or even include starting configuration 1 or configuration 2, assuming that 2 bits are required; a total of 7 bits are required, and the SI-RNTI scrambled PDCCH has 15 bits of reserved bits, which can be used to carry these indication information.

[0237] In some embodiments, at least one of the following configuration combinations is indicated by the information bits of the DCI:

[0238] SSB configuration;

[0239] PRACH configuration;

[0240] Paging configuration.

[0241] Here, adaptive switching of various signals or channels may also be indicated in combination.

[0242] In some embodiments, the method further comprises:

[0243] Define a combination list or an index list; each combination in the combination list or each index in the index list contains at least one of the following:

[0244] A value of SSB configuration;

[0245] A value of a PRACH configuration;

[0246] A value of a paging configuration;

[0247] A combination in the combination list or an index in the index list is indicated by an information bit of the DCI.

[0248] Here, different configurations of SSB or PRACH or paging may be combined, and the corresponding combination may be indicated by the DCI to obtain an adaptive indication of SSB or PRACH or Paging.

[0249] For example, assume that the combination list includes two combinations, which are represented as combination 1 and combination 2, respectively. Combination 1 includes an SSB configuration value of SSB cycle 1, a PRACH configuration value of exclusive configuration 1 start, and a paging configuration value of exclusive configuration 1 start. Combination 2 includes an SSB configuration value of SSB cycle 2, a PRACH configuration value of exclusive configuration 2 start, and a paging configuration value of exclusive configuration 1 start. One information bit of the DCI is used to indicate a combination in the combination list, for example, 0 is used to indicate combination 1, and 1 is used to indicate combination 2.

[0250] Here, different configurations of SSB or PRACH or paging can be combined to obtain different indexes, and the index value is indicated by the DCI to obtain the adaptive configuration of SSB or PRACH or Paging.

[0251] Table 3 is a schematic diagram of an index list. As shown in Table 3, it is assumed that the index list includes 4 indexes, namely 0, 1, 2, and 3, wherein index 0 includes an SSB configuration value of SSB cycle 1, a PRACH configuration value of exclusive configuration 1 start, and a paging configuration value of exclusive configuration 1 start, wherein SSB cycle 1 can represent a sparse cycle, the exclusive configuration 1 corresponding to PRACH can represent an exclusive PRACH configuration corresponding to a terminal that supports energy saving, and the exclusive configuration 1 corresponding to paging can represent a compact paging configuration. The two information bits of the DCI can be used to indicate an index in the index list, for example, 00 is used to indicate index 0, and 01 is used to indicate index 1.

[0252] Table 3

[0253] Here, considering that when there are many paging messages, the paging of traditional terminals will also be sent frequently, the network itself also needs to send information on the paging occasion (PO, Paging Occupation) configured for the traditional terminal. Therefore, the compact paging configuration configured for the R19 terminal can be deactivated, and switched to the same paging configuration as the traditional terminal, or switched to a distributed paging configuration dedicated to the R19 terminal to cope with a large number of paging messages. At this time, the terminal that has been paged needs to perform random access, so the random access configuration also needs to be switched synchronously, that is, from closing the PRACH configuration dedicated to the R19 terminal to opening it. Similarly, the SSB period is also switched from a sparse period to a dense period. Therefore, at this time, the dense period of the SSB and the exclusive configuration of the PRACH can be started through network configuration, and the exclusive configuration of paging can be started to achieve adaptive indication of SSB, PRACH, and paging.

[0254] The embodiments of the present disclosure have the following advantages:

[0255] (1) The network device sends a DCI to the terminal; wherein the DCI is used for at least one of the following: indicating the transmission configuration of the SSB; indicating the configuration of the PRACH; indicating the configuration related to paging.

[0256] In the disclosed embodiment, the configuration of signals or channels such as SSB, PRACH, and paging is adaptively indicated through the DCI.

[0257] In other words, adaptive adjustment can be made to the configuration of SSB, PRACH, paging and other signals or channels to adapt to network energy saving and the like.

[0258] (2) Adaptive switching of the configuration of signals or channels such as SSB, PRACH, and paging is applicable to terminals in connected state as well as terminals in idle or inactive state.

[0259] (3) Compared with the method of using paging DCI to indicate the adaptation of public signals in related arts, the adaptive switching of paging signals indicated by the DCI does not need to be sent on every paging occasion (PO), thus reducing network overhead.

[0260] 3 , which is a schematic diagram of an implementation flow of an information transmission method according to an embodiment of the present disclosure, and is applied to a terminal. As shown in FIG3 , the method includes step 301:

[0261] Step 301: Receive DCI sent by a network device;

[0262] The DCI is used for at least one of the following:

[0263] Indicates the transmission configuration of SSB;

[0264] Indicates the configuration of PRACH;

[0265] Indicates paging-related configuration.

[0266] Here, the DCI indicates the transmission configuration of the SSB, which can also be understood as the transmission configuration of the SSB being switched or changed from one configuration to another, and the indicated configuration is the configuration that takes effect subsequently.

[0267] Here, the DCI indicates the configuration of the PRACH, which can also be understood as the configuration of the PRACH being switched or changed from one configuration to another, and the indicated configuration is the configuration that takes effect subsequently.

[0268] Here, the DCI indicates a paging-related configuration, which can also be understood as a switch or change in the paging-related configuration, from one configuration to another, and the indicated configuration is the configuration that takes effect subsequently.

[0269] In some embodiments, the DCI is a DCI scrambled by CRC using SI-RNTI.

[0270] Here, the DCI with SI-RNTI scrambled CRC can be used to schedule the transmission of system information such as SIB1.

[0271] The following details the implementation process of adaptive indication SSB configuration, PRACH configuration, and paging configuration.

[0272] In the first case, the network device adaptively indicates the SSB configuration through DCI.

[0273] In some embodiments, the indicating the transmission configuration of the SSB includes:

[0274] Indicates that the transmission configuration of the SSB is one SSB configuration among at least two SSB configurations configured in the network device.

[0275] Here, the network device may configure the at least two SSB configurations for the terminal through system information such as SIB1 message. Because idle / inactive terminals cannot receive user-specific indication information, idle / inactive terminals can obtain the configuration through broadcast system information.

[0276] Here, the SSB may include a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast channel (PBCH).

[0277] Here, the transmission configuration indicating SSB is one of the at least two SSB configurations configured in the network device, which can also be understood as the transmission configuration of SSB being switched, that is, being switched to one of the at least two SSB configurations configured in the network device.

[0278] In some embodiments, the transmission configuration indicating the SSB is one of the at least two SSB configurations configured by the network device, including:

[0279] Indicates that the transmission period of the SSB is one SSB period of at least two SSB periods configured for the network device.

[0280] Here, the transmission period of the indicated SSB is one of the at least two SSB periods configured by the network device. It can also be understood that the transmission period of the SSB has been switched, that is, it is switched to one of the at least two SSB periods configured by the network device.

[0281] Here, the network device may configure N SSB transmission periods for the terminal through system information such as a SIB1 message, where N is an integer greater than or equal to 2. For example, the SSB transmission period may be configured as {5ms, 10ms, 20ms, 40ms, 80ms, 160ms}.

[0282] Here, the network device can adaptively adjust the transmission configuration of SSB according to the energy-saving status of the network device, the user's measurement requirements, etc., and realize adaptive switching of SSB through the DCI indication.

[0283] Specifically, when the network device, such as a base station, is in an energy-saving state, the network device can adjust the transmission period of the SSB indicated by the DCI to a larger period, that is, the transmission period of the SSB has been switched. When the period of the SSB is larger, the interval between two adjacent SSBs sent by the network device is larger, so that there is a larger interval without waking up to send the SSB, and there is a chance to enter a deeper sleep, thereby achieving energy saving on the network side, such as the base station. When there are users in the network who need to measure with a smaller SSB period, the network device can adjust the transmission period of the SSB indicated by the DCI to a smaller period, that is, the transmission period of the SSB has been switched, thereby achieving self-adaptation of the SSB period, and the self-adaptation is achieved by the period of the SSB indicated by the DCI being one of the N SSB periods configured by the network device.

[0284] Here, the adaptive switching of the SSB cycle is applicable to terminals in a connected state, and is also applicable to terminals in an idle state or an inactive state.

[0285] In the second case, the PRACH configuration is adaptively indicated through DCI.

[0286] In some embodiments, the configuration indicating the PRACH includes at least one of the following:

[0287] Indicates whether the PRACH configuration is enabled;

[0288] Indicate that the configuration index of the PRACH is one of the at least two PRACH configuration indexes configured by the network device;

[0289] Indicate that the PRACH period is one of at least two PRACH periods configured by the network device;

[0290] Indicates the validity or activation status of the PRACH association period of the PRACH;

[0291] Indicates the validity or activation status of the PRACH associated mode period of the PRACH.

[0292] Here, the network device may configure an independent PRACH configuration for a terminal supporting Network Energy Saving (NES). Accordingly, the indication of whether the PRACH configuration is enabled may mean that when an independent PRACH configuration is configured for a terminal or user supporting Network Energy Saving (NES), the DCI may indicate whether the independent PRACH configuration is enabled. When not enabled, it means that users supporting NES use the same PRACH configuration as other non-energy-saving users, such as a relatively sparse PRACH configuration; when enabled, NES users use the independently configured PRACH configuration to meet the more random access requirements of users supporting NES.

[0293] Here, when a terminal or user supporting Energy Saving (NES) has multiple PRACH configurations available, the DCI may indicate which PRACH configuration is in effect.

[0294] Here, different PRACH configurations may have different indexes. For example, different PRACH configuration indexes are configured in a higher layer parameter such as RACH-ConfigGeneric, and the DCI may indicate which PRACH configuration index to use.

[0295] Here, when the PRACH configuration provided by the network device for a terminal or user supporting network energy saving includes M period configurations, where M>1, i.e., M is an integer greater than 1, the DCI may indicate the PRACH period to be effective. For example, if the configured PRACH period includes 40ms and 80ms, the DCI indicates switching to the PRACH period corresponding to 80ms.

[0296] Here, the PRACH period may be adaptively adjusted according to the energy-saving state of the network device, the number of randomly accessed users, etc., and indicated through the DCI to achieve adaptive switching of the PRACH period.

[0297] Specifically, when the network device, such as a base station, is in an energy-saving state, the network device can adjust the PRACH period indicated by the DCI to a sparser period. By configuring a sparser period, or configuring fewer PRACH transmission opportunities within the same period, the frequency of the base station monitoring the PRACH can be reduced, thereby achieving energy saving of the base station. When the number of users who need to perform random access in the network increases, and a small amount of PRACH resources cannot meet the user access requirements, resulting in an increased probability of access collision, the network device needs to switch to a denser PRACH period, or switch to a configuration with more PRACH transmission opportunities. At this time, the network energy saving effect is poor, but the user experience is better, thereby achieving self-adaptation of the PRACH period. The self-adaptation is implemented by the DCI indicating that the PRACH period is one of the N PRACH periods configured by the network device. That is, the switching of the PRACH configuration is indicated by the indication information to achieve PRACH adaptation.

[0298] Here, for the PRACH resources in the time domain, the following three periods are defined:

[0299] The PRACH configuration period (or described as PRACH period) refers to the repetition period of random access channel opportunities (RO) occurring in the time domain before considering validity (validation) and SSB association.

[0300] The PRACH association period refers to a time length with a value range of {10, 20, 40, 80, 160}, which can ensure that each SSB actually sent is mapped to a valid random access channel opportunity (RO) at least once, and has a minimum value.

[0301] The PRACH association period may start from radio frame 0 (frame 0), and the period is an integer multiple of the PRACH configuration period, such as 1, 2, 4, 8, 16 times, but not greater than 160ms.

[0302] A PRACH association pattern period includes one or more PRACH association periods. The mapping of SSBs to ROs within each association pattern period is repeated. Since the number of valid ROs may vary in different PRACH association periods, the mapping within each association pattern period is repeated by including one or more PRACH association periods.

[0303] In some embodiments, the indication of the validity or activation status of the PRACH association period of the PRACH includes:

[0304] Indicates the validity or activation status of each M PRACH associated period; where M is an integer greater than 1.

[0305] In some embodiments, the indicating the validity or activation status of each M PRACH associated period includes:

[0306] Whether each PRACH associated period in each of the M PRACH associated periods is valid or activated is indicated in a bitmap manner.

[0307] Here, whether the function is effective or activated may also be described as whether the function can be used to transmit the PRACH.

[0308] Here, if you want to achieve energy saving at the PRACH association period level, you can configure a first time length T PAP , the first time length T PAP It is an integer multiple of the PRACH association period, assuming it is M times, and then each first time length T is indicated by an Mbit bitmap PAP The validity state or activation state of M PRACH association periods within the PRACH association period, wherein the validity state or activation state can represent whether it can be used to transmit the PRACH.

[0309] For example, M is equal to 2, the first bit represents the first PRACH association period, and the second bit represents the second PRACH association period. When the first bit is 0, it means that PRACH transmission cannot be performed in the PRACH association period corresponding to the first bit, so that network equipment such as base stations do not need to monitor in the corresponding PRACH association period, saving PRACH monitoring power consumption in the corresponding period. If the value of the first bit is 1, it means that the first PRACH association period is effective or activated. In this way, PRACH transmission can be performed in the first PRACH association period, so that the network equipment monitors in the PRACH association period.

[0310] Here, considering that the PRACH association period starts from radio frame 0 (frame0), the terminal such as UE can start from (SFN×10) mod T PAP =0 corresponds to the first bit in the M bits, the second PRACH association period corresponds to the second bit in the M bits, and so on, the Mth PRACH association period corresponds to the Mth bit in the M bits, where SFN represents the system frame number, T PAP It is an integer multiple of the PRACH association period. In this way, it is possible to determine which PRACH association period corresponds to the first bit of the M bits based on the bit indication, determine the correspondence between the M bits and the PRACH association period, and determine whether the corresponding PRACH association period allows PRACH transmission based on the bit value.

[0311] In some embodiments, the indication of the validity or activation status of the PRACH associated mode period of the PRACH includes:

[0312] Indicates the validity or activation status of every L PRACH associated mode periods; where L is an integer greater than 1.

[0313] In some embodiments, the indicating the validity or activation status of each L PRACH associated mode period includes:

[0314] Whether each PRACH associated mode period in each L PRACH associated mode periods is valid or activated is indicated in a bitmap manner.

[0315] Here, whether the function is effective or activated may also be described as whether the function can be used to transmit the PRACH.

[0316] Here, for energy saving at the PRACH association pattern period level, a second time length T can also be defined. PAPP , the second time length T PAPP It is an integer multiple of the PRACH association pattern period, assuming it is L times, and then each second time length T is indicated by an L bit bitmap PAPPThe validity status or activation of the L PRACH association pattern periods within the association pattern period, or whether they are available.

[0317] For example, L is equal to 2, the first bit represents the first PRACH association pattern period, and the second bit represents the second PRACH association pattern period. When the first bit is 0, it indicates that PRACH transmission cannot be performed in the corresponding PRACH association pattern period, so that network devices such as base stations do not need to monitor in the corresponding PRACH association pattern period, saving PRACH monitoring power consumption in the corresponding period. If the value of the first bit is 1, it indicates that the first PRACH association pattern period is effective or activated. In this way, PRACH transmission can be performed in this PRACH association pattern period, and the network device monitors in this PRACH association pattern period.

[0318] Here, considering that the PRACH association pattern period also starts from radio frame 0 (frame 0), the terminal such as UE can start from (SFN×10) mod T PAPP =0 corresponds to the first bit in the L bits, the second PRACH association pattern period corresponds to the second bit in the L bits, and so on, the Lth PRACH association pattern period corresponds to the Lth bit in the L bits, where SFN represents the system frame number, T PAPP It is an integer multiple of the PRACH association pattern period. In this way, it is possible to determine which PRACH association pattern period corresponds to the first bit of the L bits based on the bit indication, determine the correspondence between the L bits and the PRACH association pattern period, and determine whether the corresponding PRACH association pattern period allows PRACH transmission based on the bit value.

[0319] In the third case, the paging configuration is adaptively indicated through DCI.

[0320] In some embodiments, the configuration indicating paging-related information includes at least one of the following:

[0321] Indicates whether the paging configuration is effective;

[0322] The paging configuration indicated to be in effect is one of the at least two paging configurations configured in the network device.

[0323] Here, the network device can configure a set of paging configurations for traditional terminals that do not support NES, and a set of special paging configurations for terminals that support NES. Accordingly, the indication of whether the paging configuration is effective can be understood as indicating whether the paging configuration corresponding to the terminal that supports NES is enabled to achieve adaptive paging configuration. When the paging configuration corresponding to the terminal that supports NES is not enabled, the network will transmit paging less frequently, and the paging capacity will also be smaller, but the network energy consumption can be lower. When the paging configuration corresponding to the terminal that supports NES is enabled, the capacity for accommodating paging becomes larger, but compared to switching to a similar traditional distributed paging configuration with a shorter adjacent PF (paging frame) interval, the network energy consumption is lower.

[0324] For example, when a dedicated paging configuration is configured for a Network Energy Saving (NES) terminal, the NES terminal can be instructed to use the dedicated paging configuration or a paging configuration dedicated to other non-NES terminals. For example, a "0" indication bit indicates the use of a paging configuration dedicated to other non-NES terminals, while a "1" indication bit indicates the use of a paging configuration dedicated to NES terminals.

[0325] Here, the paging configuration indicated to be effective is one of at least two network configurations, which can be understood as a paging configuration switch, that is, switching to one of the at least two paging configurations configured by the network device, that is, indicating which paging configuration to use subsequently.

[0326] Here, the network device may also configure two sets of paging configurations for the terminal supporting NES, one set supporting fewer paging occasions and the other set supporting more paging occasions, so as to adapt between the two sets. The configuration may be performed through SIB1 messages.

[0327] For example, the network device can configure at least two dedicated paging configurations for NES terminals, using an indication message to indicate which paging configuration to use after a certain application time. For example, a compact paging configuration 1 can be configured, where all paging opportunities are concentrated within a short window within the entire paging cycle, and a paging configuration 2 can be configured, similar to traditional paging, where paging opportunities are evenly distributed throughout the paging cycle. When the paging probability increases to a certain level, the device switches to paging configuration 2, which can accommodate more paging capacity.

[0328] In some embodiments, the receiving DCI sent by the network device includes:

[0329] The DCI sent by the network device is received at a fixed transmission timing or any transmission timing of the PDCCH carrying the DCI.

[0330] Here, the network device on the sending side may send the DCI carrying the above indication message to the terminal at each transmission opportunity of the PDCCH carrying the DCI.

[0331] Here, the receiving terminal can choose to Adapt The DCI may be received at a fixed transmission opportunity of the PDCCH carrying the DCI within the period, or at any transmission opportunity of the PDCCH carrying the DCI within the period. Adapt It should be a multiple of 20ms or 160ms.

[0332] It should be noted that in this way, the frequency of adaptive changes in SSB configuration, PRACH configuration, and paging configuration is allowed to be every T Adapt Supporting the change once has higher flexibility compared with the adaptive indication carried by paging DCI proposed in the related technical solutions.

[0333] In some embodiments, the receiving DCI sent by the network device includes:

[0334] According to a first period, receiving the DCI sent by the network device;

[0335] The first period is a multiple of the transmission period of SIB1 or a multiple of the transmission repetition period of SIB1.

[0336] Here, the network device on the sending side may periodically send the DCI carrying the above indication information, and the first period of sending the DCI is T Adapt , usually T Adapt It should be a multiple of 20ms or 160ms.

[0337] For example, only when (SFN×10) mod T Adapt =0, wherein SFN represents the system frame number, mod represents the modulus operation, and T Adapt Indicates that the DCI is sent in the first cycle or the nth transmission opportunity, where n is less than the maximum number of transmission opportunities in each cycle. The corresponding receiving side also detects the indication information at the corresponding position to determine whether adaptive switching of the SSB configuration, PRACH configuration, and paging configuration occurs.

[0338] In some embodiments, different information bits in the DCI respectively indicate at least one of the following:

[0339] SSB configuration;

[0340] PRACH configuration;

[0341] Paging configuration.

[0342] For example, assuming that the SSB includes 2 cycle switches, 1 bit is required; the PRACH may include whether to start, or even include starting configuration 1 or configuration 2, assuming that 2 bits are required. If the indication of the PRACH association period is considered, it is assumed that M bits are required, M=4; the adaptation of the paging configuration may include whether to start, or even include starting configuration 1 or configuration 2, assuming that 2 bits are required; a total of 7 bits are required, and the SI-RNTI scrambled PDCCH has 15 bits of reserved bits, which can be used to carry these indication information.

[0343] In some embodiments, the information bits of the DCI indicate a combination of at least one of the following configurations:

[0344] SSB configuration;

[0345] PRACH resource configuration;

[0346] Paging configuration.

[0347] In some embodiments, the method further comprises:

[0348] Define a combination list or an index list; each combination in the combination list or each index in the index list contains at least one of the following:

[0349] A value of SSB configuration;

[0350] A value of a PRACH configuration;

[0351] A value of a paging configuration;

[0352] A combination in the combination list or an index in the index list is indicated by an information bit of the DCI.

[0353] Here, different configurations of SSB or PRACH or paging may be combined, and the corresponding combination may be indicated by the DCI to obtain an adaptive indication of SSB or PRACH or Paging.

[0354] For example, assume that the combination list includes two combinations, which are represented as combination 1 and combination 2, respectively. Combination 1 includes an SSB configuration value of SSB cycle 1, a PRACH configuration value of exclusive configuration 1 start, and a paging configuration value of exclusive configuration 1 start. Combination 2 includes an SSB configuration value of SSB cycle 2, a PRACH configuration value of exclusive configuration 2 start, and a paging configuration value of exclusive configuration 1 start. One information bit of the DCI is used to indicate a combination in the combination list, for example, 0 is used to indicate combination 1, and 1 is used to indicate combination 2.

[0355] Here, different configurations of SSB or PRACH or paging can be combined to obtain different indexes, and the index value is indicated by the DCI to obtain the adaptive configuration of SSB or PRACH or Paging.

[0356] For example, assume that the index list includes 4 indexes, namely 0, 1, 2, and 3, where index 0 contains an SSB configuration value of SSB cycle 1, a PRACH configuration value of exclusive configuration 1 start, and a paging configuration value of exclusive configuration 1 start, where SSB cycle 1 can represent a sparse cycle, the exclusive configuration 1 corresponding to PRACH can represent an exclusive PRACH configuration corresponding to a terminal that supports energy saving, and the exclusive configuration 1 corresponding to paging can represent a compact paging configuration. The two information bits of the DCI can be used to indicate an index in the index list, for example, 00 is used to indicate index 0, and 01 is used to indicate index 1.

[0357] The embodiments of the present disclosure have the following advantages:

[0358] (1) The network device sends a DCI to the terminal; wherein the DCI is used for at least one of the following: indicating the transmission configuration of the SSB; indicating the configuration of the PRACH; indicating the configuration related to paging.

[0359] In the disclosed embodiment, the configuration of signals or channels such as SSB, PRACH, and paging is adaptively indicated through the DCI.

[0360] In other words, adaptive adjustment can be made to the configuration of SSB, PRACH, paging and other signals or channels to adapt to network energy saving and the like.

[0361] (2) Adaptive switching of the configuration of signals or channels such as SSB, PRACH, and paging is applicable to terminals in connected state as well as terminals in idle or inactive state.

[0362] (3) Compared with the method of using paging DCI to indicate the adaptation of public signals in related arts, the adaptive switching of paging signals indicated by the DCI does not need to be sent on every paging occasion (PO), thus reducing network overhead.
