Detailed Description

Before the technical scheme of the embodiment of the application is introduced, related technology is introduced.

In the related art, network energy saving is an important means for reducing the operation expenditure (opex) of operators and realizing 5G development. The network energy saving method comprises the aspects of time domain, frequency domain, power domain, space domain and the like. The energy saving under the condition that the network serves the connected state User is studied intensively, for example, a cell Discontinuous Transmission (DTX) or Discontinuous Reception (DRX) mechanism is introduced for increasing the time domain turn-off time, the network can periodically enter a non-active period, the transmission of periodic/semi-persistent reference signals such as channel state information reference signals (CSI-RS) is reduced in the non-active period, the transmission power consumption of a base station is reduced, user Equipment (UE) does not perform transmission of periodic CSI report any more, and periodic/semi-persistent Sounding Reference Signals (SRS) are transmitted, so that the receiving power consumption of the base station is reduced, new data scheduling is not performed any more, and the transmission and the reception of semi-persistent scheduled physical downlink shared channels (SPS-PDSCH) and configuration authorized physical uplink shared channels (CG-PUSCH) are stopped. And a secondary cell (Scell) without SSB (SSB-Less) is introduced in the frequency domain, so that the base station can have more occasions to turn off the Scell, thereby realizing energy conservation. The antenna array of the airspace introduction self-adaption is turned off, and the power domain introduction self-adaption PDSCH transmission power adjustment can realize network energy saving.

However, in the above-described power saving scheme, in order to reduce the impact on idle or inactive UEs, the configuration of signals or channels transmitted in broadcast form, such as SSB, SIB1, PRACH, paging, etc., is not adaptively adjusted.

Specifically, it may include:

First, considering that when a cell is not served by a user, a periodic broadcast signal still needs to be transmitted, so that the base station cannot enter a deep sleep state, which will affect the energy saving effect of the base station. For this reason, the adaptation of the broadcast signal will be further studied, and one of the most straightforward energy-saving ways is to reduce the transmission period of SSB and SIB1 signals, transmit with a thinner transmission density, and increase the time interval between two adjacent transmissions, so that the network can enter a deeper sleep state.

Second, for PRACH, when the network configures PRACH resources, the network needs to detect the PRACH all the time no matter whether there is a PRACH transmitted by the UE, which also causes the power consumption of the base station to become large.

Third, for paging messages, since the paging timing of users in a cell is dispersed in the DRX cycle as uniformly as possible in the existing paging configuration, when a base station transmits a paging message, especially for paging message update or short message (short message) transmission, each paging frame (PAGING FRAME) needs to transmit related information, so that the message needs to be transmitted at uniform intervals in the whole DRX cycle, and the base station cannot enter into long-time deep sleep, thereby having large power consumption.

For the above-mentioned energy saving of how the broadcast signal or channel adapts to the base station, related technology proposes to perform SSB transmission adaptation by reducing the SSB transmission density, introducing two sets of PRACH configurations, the second set of PRACH on-demand adaptive transmission, introducing compact paging (paging) configuration, and implementing energy saving by performing centralized transmission instead of uniformly distributed transmission in one DRX cycle. However, it must be considered that the adaptation of these broadcast signals or channels will affect terminals in idle and inactive states, which cannot receive terminal-specific control information and RRC messages to indicate the adaptation of these broadcast signals or channels, since there is no access cell.

In the related art, it is proposed to use paging DCI to indicate adaptation of a common signal, but one problem with paging message is that since it needs to be broadcasted to all terminals, once adaptation occurs, the network needs to send paging DCI on every paging occasion (PO, paging Occasion) even though it is not needed to send paging message to the terminals, resulting in a large network overhead.

Based on the above, in the embodiment of the application, the network equipment sends Downlink Control Information (DCI) to the terminal, wherein the DCI is used for at least one of indicating transmission configuration of a Synchronous Signal Block (SSB), indicating configuration of a Physical Random Access Channel (PRACH) and indicating paging related configuration.

Referring to fig. 1, fig. 1 is a schematic flow chart of an implementation of an information transmission method according to an embodiment of the present application, which is applied to a network device, as shown in fig. 1, and the method includes step 101:

Step 101, transmitting DCI to a terminal;

wherein the DCI is for at least one of:

indicating a transmission configuration of the SSB;

Indicating a configuration of the PRACH;

indicating a paging related configuration.

Here, the DCI indicates the transmission configuration of the SSB, which may be understood as a change or a handover of the transmission configuration of the SSB, and is adjusted from one configuration to another, where the indicated configuration is a configuration that is subsequently validated.

Here, the DCI indicates the configuration of the PRACH, which may also be understood as that the configuration of the PRACH is switched or changed, and is adjusted from one configuration to another, where the indicated configuration is a configuration that is subsequently validated.

Here, the DCI indicates a paging-related configuration, which may also be understood as that the paging-related configuration is switched or changed, and is adjusted from one configuration to another, and the indicated configuration is a configuration that is subsequently validated.

In some embodiments, the DCI is DCI scrambled by a Cyclic Redundancy Check (CRC) with a system information radio network temporary identity (SI-RNTI).

Here, the SI-RNTI scrambles DCI of the CRC may be used to schedule transmission of system information such as SIB 1.

Wherein SIB1 is transmitted on a DownLink shared channel (DL-SCH, downLink SHARED CHANNEL) with a period of 160ms and a variable transmission repetition period within 160 ms. The default transmission repetition period of SIB1 is 20ms, but the actual transmission repetition period depends on the network implementation. For Synchronization Signal Block (SSB), synchronization SIGNAL AND PBCH Block, and control resource set (CORESET, control Resource Set) multiplexing mode 1, the sib1 repetition transmission period is 20ms. For SSB and CORESET multiplexing modes 2/3, the sibb 1 transmission repetition period is the same as the SSB period. SIB1 includes information about the availability and scheduling of other SIBs (e.g., SIB to SI message mapping, periodicity, SI window size) and an indication of whether one or more SIBs are provided only on demand, and in this case, the User Equipment (UE) performs the configuration required for the system information (SI, system Information) request. SIB1 is a cell-specific SIB. For convenience of description, those occasions when SIB1 is transmitted are called SIB1 transmission time, SO for short.

The following is the information field included in the DCI scheduling SIB1 message, the DCI format is DCI 1_0, and the DCI is DCI scrambling CRC by SI-RNTI:

frequency domain resource allocation, occupation Bits, wherein, the bit number is equal to the bit number,The RB number, which is the size CORESET 0 in the Downlink (DL) BandWidth Part (BWP);

Time domain resource allocation occupies 4bits;

Mapping from Virtual Resource Blocks (VRB) to Physical Resource Blocks (PRB), occupying 1bit;

A modulation and coding scheme occupies 5bits;

Redundancy version, occupying 2bits;

System information indicates that 1bit is occupied;

reserved bits occupy 17bits for operation in cells with shared spectrum channel access, otherwise 15bits.

From the above it can be seen that there is a 17 bit reservation in case of shared spectrum access, otherwise there is a 15 bit reservation, so the above indicated information can be carried by the reserved bits.

The implementation procedure of the adaptive indication SSB configuration, the PRACH configuration and the paging configuration is described in detail below.

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

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

Here, the network device may configure the at least two SSB configurations for the terminal through system information such as SIB1 message. Since the idle state/inactive state terminal cannot receive the user-specific indication information, the idle state/inactive state terminal can obtain the user-specific indication information when the broadcasted system information is configured.

Here, the SSB may include a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS), and a Physical Broadcast Channel (PBCH).

Here, the transmission configuration of the indicated SSB is one SSB configuration of at least two SSB configurations of the network device configuration, which may also be understood as a switching of the transmission configuration of the SSB, i.e. to one SSB configuration of at least two SSB configurations of the network device configuration.

In some embodiments, the transmission configuration indicating SSB is one of at least two SSB configurations of the network device configuration, comprising:

Here, the transmission period of the indication SSB is one SSB period of at least two SSB periods configured by the network device, which may also be understood as that the transmission period of the SSB is switched, that is, switched to one SSB period of at least two SSB periods configured by the network device.

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

Here, the network device may adaptively adjust the transmission configuration of the SSB according to the power saving state of the network device, the measurement requirement of the user, and the like, and the DCI indicates the transmission configuration to implement adaptive handover of the SSB.

Specifically, when the network device, such as a base station, is in an energy-saving state, the network device may adjust the transmission period of the SSB indicated by the DCI to a larger period, that is, the transmission period of the SSB is switched, and when the period of the SSB is larger, the interval between two adjacent SSBs sent by the network device is larger, so that there may be a larger interval without waking up to send the SSB, and there is a chance to enter deeper sleep, so as to realize energy saving of the network side, such as the base station. When there is a need for measurement of a smaller SSB period for a user in the network, the network device may adjust the transmission period of the SSB indicated by the DCI to be the smaller period, that is, the transmission period of the SSB is switched, so as to implement adaptation of the SSB period, where the adaptation implementation manner is implemented by using the DCI to indicate that the period of the SSB is one of N SSB periods configured by the network device.

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

Considering that the SSB is the information to be first identified by the terminal access cell, the time-frequency resource position of a physical downlink control channel (type 0-PDCCH, type0-Physical Downlink Control Channel) with type0 can be obtained by reading the information in the PBCH contained in the SSB, so that the scheduling information of the SIB1 is obtained. Therefore, if the SSB configuration is to be acquired through the SIB1 message, for the cells independently available for the idle state or inactive (inactive) state terminal to access, the terminal needs a long time of synchronization signal search, and after the SSB is detected, the corresponding SIB1 is acquired to know the transmission period information of the SSB of the current cell.

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

In some embodiments, the indicating the configuration of the PRACH comprises at least one of:

Indicating whether configuration of the PRACH is enabled;

Here, the network device may configure an independent PRACH configuration for a terminal supporting Network Energy Saving (NES), and accordingly, the indicating whether the configuration of the PRACH is enabled may refer to whether the independent PRACH configuration is enabled when the independent PRACH configuration is configured for a terminal or a user supporting Network Energy Saving (NES). When not enabled, it means that the NES-enabled user uses the same PRACH configuration, e.g., a relatively sparse PRACH configuration, as the other non-energy saving users, and when enabled, the NES user uses the independently configured PRACH configuration to meet the more random access requirements of the NES-enabled user.

Here, when a terminal or user supporting energy saving (NES) has multiple sets of PRACH configurations available, the DCI may indicate which set the PRACH configuration is in effect.

Here, different PRACH configurations may have different indexes. For example, configuring different PRACH configuration indexes (Configuration Index) in higher layer parameters such as RACH-ConfigGeneric, the DCI may indicate which PRACH configuration index to use.

Here, as shown in table 1, the terminal, for example, the UE, through the PRACH configuration index (Configuration Index), can correspond to parameters such as a preamble (preamble) format, a system frame for transmitting the PRACH (nSFNmodx =y is satisfied, where nSFN indicates a radio frame where the PRACH period is located, x indicates the PRACH period, y indicates a location of the PRACH resource where the radio frame is located in the PRACH period), a subframe location, a start symbol, a number of PRACH slots in a subframe, a number of PRACH opportunities (occalations) in one PRACH slot, and a duration of the PRACH.

TABLE 1

Here, when the PRACH configuration provided by the network device for a terminal or user supporting network power 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 validated. For example, the configured PRACH period includes 40ms,80ms, and the DCI indicates to switch to the PRACH period corresponding to 80 ms.

Here, the period of the PRACH may be adaptively adjusted according to the energy saving state of the network device, the number of users accessing randomly, and the like, and the indication is performed through the DCI, so as to implement adaptive switching of the period of the PRACH.

Specifically, when the network device, such as a base station, is in an energy-saving state, the network device may adjust the period of the PRACH indicated by the DCI to a sparse period, and by configuring the PRACH with the sparse period or configuring fewer transmission opportunities in the same period, the frequency of the base station monitoring the PRACH may be reduced, so as to achieve energy saving of the base station. When the number of users needing random access in the network increases, a small amount of PRACH resources cannot meet the access requirements of the users, and the access collision probability increases, the network equipment needs to be switched to a denser PRACH period or to be switched to a configuration with more PRACH transmission opportunities, and at the moment, the network energy-saving effect is poor, but the user experience is good, so that the self-adaption of the PRACH period is realized. The adaptive implementation mode is implemented by indicating the period of the PRACH to be one of N PRACH periods configured by the network equipment through the DCI. That is, the indication information indicates the switching of the PRACH configuration, so as to achieve the self-adaptation of the PRACH.

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

The PRACH configuration period (or described as PRACH period) refers to a repetition period of a random access channel occasion (RO) occurring in the time domain before consideration of validity and SSB association. Corresponding to x in table 1 above.

The PRACH association period (association period) is a time length with a value range {10,20,40,80,160}, which can satisfy that each SSB actually transmitted is mapped to an effective random access channel (RO) at least once, and the value is the smallest.

Wherein, the PRACH association period (PRACH association period) may refer to starting 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.

The PRACH association pattern period (association pattern period) includes one or more PRACH association periods, and the SSB-to-RO mapping within each association pattern period (association pattern period) is repeated. Since the number of valid ROs in different PRACH association periods may be different, it is ensured that the mapping within each association pattern period is repeated by including one or more PRACH association periods.

Referring to fig. 2, fig. 2 is a schematic diagram of a relationship among a PRACH configuration period, a PRACH association period, and a PRACH association pattern period.

Table 2 is a mapping relationship of PRACH configuration period and SSB to PRACH association period, as shown in table 2, one PRACH association period, starting from frame 0, the association period for mapping SSB index to PRACH occasion (Occasion) is the minimum value in the set determined by PRACH configuration period according to table 2, such thatThe SSB indices are mapped to PRACH occalation at least once within the association period, where the UE obtains from the SSB-PositionInBurst values in SIB1 or ServingCellConfigCommonIf there is a set of PRACH occasions that are not mapped after an integer number of SSB indices are mapped to PRACH occasions within the association periodThe SSB indices indicate that no SSB index is mapped to the set of PRACH occasions. The association pattern period comprises one or more association periods and is determined such that the mapping pattern between PRACH occasions and SSB block indexes repeats at most once every 160 milliseconds, after an integer number of association periods (if any) PRACH occasions are not associated with SSB indexes and are not used for PRACH transmission either.

TABLE 2

In some embodiments, the indicating an effective or active state of a PRACH association period of a PRACH comprises:

In some embodiments, the indicating the effective or active state per M PRACH association periods comprises:

Here, whether the PRACH is validated or activated may also be described as available for transmission.

Here, if the PRACH association period (association period) level of power saving is to be achieved, a first time length T _PAP may be configured, where the first time length T _PAP is an integer multiple of the PRACH association period (association period), assumed to be M times, and then the effective state or active state of the M PRACH association periods (association period) within each first time length T _PAP is indicated by a bitmap (bitmap) of Mbit.

For example, M is equal to 2, the first bit (bit) indicates a first PRACH association period (association period), the second bit indicates a second PRACH association period (association period), and when the first bit is 0, it indicates that the transmission of the PRACH cannot be performed in the PRACH association period (association period) corresponding to the first bit, so that the network device, such as the base station, does not need to monitor in the corresponding PRACH association period, and PRACH monitoring power consumption in the corresponding period is saved. If the first bit has a value of 1, it indicates that the first PRACH association period (association period) is active or active, so that the first PRACH association period (association period) enables transmission of PRACH, and the network device listens during the PRACH association period (association period).

Here, considering that the PRACH association period (association period) is started from the radio frame0 (frame 0), the terminal, e.g., UE, may correspond to the 1 st bit of M bits from the 1 st PRACH association period position determined by (sfn×10) mod T _PAP =0, the 2 nd PRACH association period corresponds to the 2 nd bit of M bits, and so on, the M PRACH association period corresponds to the M th bit of M bits, wherein SFN represents a system frame number, T _PAP is an integer multiple of the PRACH association period (association period), so that it may be determined which first PRACH association period corresponds to the first bit of M bits according to the bit indication, the correspondence between M bits and PRACH association period may be determined, and whether the corresponding PRACH association period allows transmission of PRACH according to the value of the bits.

In some embodiments, the indicating an effective or active state of a PRACH association mode period of a PRACH comprises:

In some embodiments, the indicating the effective or active state per L PRACH association mode periods comprises:

Here, for the PRACH association pattern period level of energy saving, a second time length T _PAPP may also be defined, where the second time length T _PAPP is an integer multiple of PRACH association pattern period, assuming L times, and then the validation state or activation of L PRACH association pattern period in each second time length T _PAPP is indicated by the bitmap of the L bits.

For example, L is equal to 2, the first bit (bit) indicates a first PRACH association pattern period, the second bit indicates a second PRACH association pattern period, and when the first bit is 0, it indicates that transmission of PRACH cannot be performed in the corresponding PRACH association pattern period, so that the network device, such as the base station, does not need to monitor in the corresponding PRACH association pattern period, and PRACH monitoring power consumption in the corresponding period is saved. If the value of the first bit is 1, the first PRACH association mode period is validated or activated, so that the PRACH transmission can be performed in the PRACH association mode period, and the network equipment monitors in the PRACH association mode period.

Here, considering that PRACH association pattern period also starts from radio frame 0 (frame 0), the terminal, such as UE, may correspond to 1 st bit of L bits from a position determined by (sfn×10) mod T _PAPP =0, 2 nd PRACH association pattern period corresponds to 2 nd bit of L bits, and so on, L PRACH association pattern period corresponds to L th bit of L bits, wherein SFN represents a system frame number, T _PAPP is an integer multiple of PRACH association pattern period, so that it may be determined which first PRACH association pattern period corresponds to the first bit of L bits according to bit indication, the correspondence between L bits and PRACH association pattern period may be determined, and whether or not corresponding PRACH association pattern period allows transmission of PRACH according to a bit value.

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

In some embodiments, the indicating paging related configuration includes at least one of:

indicating whether the paging configuration is in effect;

Here, the network device may configure a set of paging configurations for terminals that do not conventionally support NES, and a set of dedicated paging configurations for terminals that support NES. Accordingly, the indication of whether the paging configuration is effective may be understood as indicating whether the paging configuration corresponding to the NES-supporting terminal is enabled to implement the adaptation of the paging configuration. When the paging configuration corresponding to the NES supporting terminal is not enabled, the paging time of the network is less, and the paging capacity is smaller, but the network energy consumption can be smaller. When the paging configuration corresponding to the NES-enabled terminal is enabled, the capacity of the accommodated page becomes larger, but the power consumption of the network is smaller than in a similar conventional distributed paging configuration switched to a shorter adjacent PF (paging frame) interval.

For example, when a specific paging configuration is configured for a Network Energy Saving (NES) terminal, the NES terminal may be instructed to use the specific paging configuration or to use other non-NES terminal specific paging configurations. For example, an indication bit of "0" indicates that other non-NES terminal-specific paging configurations are used, and an indication bit of "1" indicates that NES terminal-specific paging configurations are used.

Here, the paging configuration indicating that the validity is one of at least two network configurations may be understood as that the paging configuration is switched, i.e. switched to one of the at least two paging configurations of the network device configuration. I.e. indicating which paging configuration to use subsequently.

Here, the network device may also configure 2 sets of paging configurations for the terminals supporting NES, one set supporting fewer paging occasions, one set supporting more paging occasions, so as to adapt between the two sets. Configuration may be via SIB1 message.

For example, the network device may configure the NES terminal with at least 2 specific paging configurations, which one the paging configuration used after a certain effective time (application time) is indicated by an indication message. For example, a compact paging configuration 1 may be configured, wherein all paging occasions are concentrated within a short time window of the entire paging cycle, and a paging configuration 2 similar to conventional paging, which is uniformly dispersed throughout the entire paging cycle, is further configured. When the paging probability increases to a certain extent, switching to paging configuration 2 can accommodate more paging capacity.

Here, the principle of Paging (Paging) energy saving is similar to PRACH, but corresponds to power consumption transmitted by a network device such as a base station, and PRACH corresponds to power consumption received by a network device such as a base station.

In some embodiments, the sending DCI to a terminal includes:

and sending the DCI to the terminal at each transmission opportunity of the PDCCH carrying the DCI.

Here, the network device on the transmitting side may send the DCI carrying the above indication message to the terminal at every transmission opportunity of the PDCCH carrying the DCI.

Here, the terminal on the receiving side may receive the DCI at a fixed transmission timing at which the PDCCH carrying the DCI may be selected in the period T _Adapt, or may receive the DCI at any transmission timing at which the PDCCH carrying the DCI may be selected in the period. Typically T _Adapt should be a multiple of 20ms, or a multiple of 160 ms.

It should be noted that, in this way, the frequency of the adaptive changes of the SSB configuration, the PRACH configuration, and the paging configuration is allowed to be changed once per T _Adapt support, which has higher flexibility compared with the adaptive indication carried by paging DCI proposed in the related technical solution.

In some embodiments, the sending DCI to a terminal includes:

transmitting the DCI to the terminal according to a first period;

Here, the network device on the transmitting side may periodically transmit the DCI carrying the above indication information, where the first period of transmitting the DCI is T _Adapt, and typically T _Adapt should be a multiple of 20ms, or a multiple of 160 ms.

For example, the DCI is transmitted to the terminal only on the first transmission occasion at which the frame start satisfying (sfn×10) mod T _Adapt =0, where SFN represents a system frame number, mod represents a remainder, T _Adapt represents the first period, or on the nth transmission occasion, where n is smaller than the maximum number of transmission occasions in each first period. The corresponding receiving side also detects the indication information at the corresponding position and judges whether the self-adaptive switching of SSB configuration, PRACH configuration and paging configuration occurs or not.

In some embodiments, at least one of the following is indicated by different information bits in the DCI, respectively:

SSB configuration;

PRACH configuration;

Paging configuration.

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

For example, assuming that SSB contains 2 period handovers, requiring 1 bit, PRACH may contain whether to initiate or even contain initiation of configuration 1 or configuration 2, assuming 2 bits are required, if considering the indication of PRACH association period (association period), assuming M bits are required, m=4, adaptation of paging configuration may contain whether to initiate or even contain initiation of configuration 1 or configuration 2, assuming 2 bits are required, 7 bits are required altogether, SI-RNTI scrambled PDCCH has 15 bits of reserved bits, through which these indication information can be carried.

In some embodiments, the combination of at least one of the following configurations is indicated by information bits of the DCI:

SSB configuration;

PRACH configuration;

Paging configuration.

Here, adaptive switching of individual signals or channels may also be indicated in combination.

In some embodiments, the method further comprises:

a value of SSB configuration;

A value of PRACH configuration;

a value of paging configuration;

Here, different configurations of SSB or PRACH or Paging (Paging) may be combined, with corresponding combinations indicated by the DCI to obtain an adaptive indication of SSB or PRACH or Paging.

For example, assuming that the combination list includes 2 combinations, denoted as combination 1 and combination 2, respectively, wherein the combination 1 includes an SSB configuration with a value of SSB period 1, a PRACH configuration with a value of dedicated configuration 1 and a paging configuration with a value of dedicated configuration 1, the combination 2 includes an SSB configuration with a value of SSB period 2, a PRACH configuration with a value of dedicated configuration 2 and a paging configuration with a value of dedicated configuration 1, one of the combinations in the combination list is indicated by 1 information bit of the DCI, for example, combination 1 is indicated by 0 and combination 2 is indicated by 1.

Here, different configurations of SSB or PRACH or Paging (Paging) may be combined to obtain different indexes, and the index value is indicated through the DCI to obtain an adaptive configuration of SSB or PRACH or Paging.

Table 3 is an illustration of an index list, as shown in table 3, assuming that the index list includes 4 indexes, namely 0, 1, 2 and 3, where the value of one SSB configuration included in the index 0 is SSB period 1, the value of one PRACH configuration is dedicated configuration 1 and the value of one paging configuration is dedicated configuration 1 and is started, where SSB period 1 may represent a sparse period, dedicated configuration 1 corresponding to PRACH may represent dedicated PRACH configuration corresponding to a terminal supporting energy saving, dedicated configuration 1 corresponding to paging may represent compact paging configuration, and one index in the index list may be indicated by 2 information bits of the DCI, for example, index 0 is indicated by 00 and index 1 is indicated by 01.

TABLE 3 Table 3

Here, considering that paging of the legacy terminal is frequently transmitted when paging messages are more, information is also required to be transmitted on paging occasions (POs, paging Occation) configured for the legacy terminal by the network itself, the paging configuration of compact (compact) configured for the R19 terminal may be deactivated, switched to use the same paging configuration as the legacy terminal, or switched to a distributed paging configuration dedicated for the R19 terminal to cope with a large number of paging messages. At this time, the terminal after being paged needs to perform random access, so that the random access configuration also needs to be switched synchronously, that is, switched from the PRACH configuration dedicated for the closed R19 terminal to the open state. The same SSB period is also switched from a sparse period to a dense period, so that the SSB, the PRACH and the paging can be adaptively indicated by starting the dense period of the SSB and the dedicated configuration of the PRACH through the network configuration and starting the dedicated configuration of the paging (paging).

The embodiment of the application has the following advantages:

(1) The network equipment sends DCI to the terminal, wherein the DCI is used for at least one of indicating the transmission configuration of SSB, indicating the configuration of PRACH and indicating the paging related configuration.

In the embodiment of the application, the configuration of signals or channels such as SSB, PRACH, paging and the like is adaptively indicated through the DCI.

That is, adaptive adjustment of the configuration of SSB, PRACH, paging, etc. signals or channels may be implemented to adapt to network power saving, etc.

(2) The self-adaptive switching of the configuration of signals or channels such as SSB, PRACH, paging and the like is suitable for the terminal in a connection state and also suitable for the terminal in an idle state or a non-active state.

(3) By the adaptive switching of the paging signal indicated by the DCI, there is no need to transmit at each paging occasion (PO, paging Occasion) compared to the related art method of indicating the adaptation of the common signal using the paging DCI, and thus network overhead can be reduced.

The PRACH configuration period (or described as PRACH period) refers to a repetition period of a random access channel occasion (RO) occurring in the time domain before consideration of validity and SSB association.

Here, if the PRACH association period (association period) level of power saving is to be achieved, a first time length T _PAP may be configured, where the first time length T _PAP is an integer multiple of the PRACH association period (association period), assumed to be M times, and then an effective state or an active state of the M PRACH association periods (association period) within each first time length T _PAP is indicated by a bitmap (bitmap) of Mbit, where the effective state or the active state may characterize whether the PRACH is available for transmission.

Here, considering that the PRACH association period (association period) is started from the radio frame0 (frame 0), the terminal, e.g., UE, may correspond to the 1 st bit of M bits from the 1 st PRACH association period position determined by (sfn×10) mod T _PAP =0, the 2 nd PRACH association period corresponds to the 2 nd bit of M bits, and so on, the M PRACH association period corresponds to the M th bit of M bits, wherein SFN represents a system frame number, T _PAP is an integer multiple of the PRACH association period (association period), and thus, it may be determined which PRACH association period corresponds to the first bit of M bits according to the bit indication, determine the correspondence between M bits and PRACH association period, and determine whether the corresponding PRACH association period allows transmission of PRACH according to the value of the bits.

Here, for the PRACH association pattern period level of energy saving, a second time length T _PAPP may also be defined, where the second time length T _PAPP is an integer multiple of PRACH association pattern period, assuming L times, and then indicates the validation state or activation, or availability, of the L PRACH association pattern period in each second time length T _PAPP by the bitmap of the L bits.

Here, considering that PRACH association pattern period also starts from radio frame 0 (frame 0), the terminal, such as UE, may correspond to 1 st bit of L bits from a position determined by (sfn×10) mod T _PAPP =0, 2 nd PRACH association pattern period corresponds to 2 nd bit of L bits, and so on, L PRACH association pattern period corresponds to L th bit of L bits, wherein SFN represents a system frame number, T _PAPP is an integer multiple of PRACH association pattern period, so that it may be determined which PRACH association pattern period corresponds to the first bit of L bits according to bit indication, the correspondence of L bits to PRACH association pattern period may be determined, and whether or not corresponding PRACH association pattern period allows transmission of PRACH according to the value of bits.
