Message transmission method and device, storage medium and program product

[0001] Cross-reference to Related Applications

[0002] The present disclosure claims priority from Chinese Patent Application No. 202411385388.1 filed on September 30, 2024 in China, the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0003] The present disclosure relates to the field of communication technology, and in particular to a message transmission method, device, storage medium and program product. BACKGROUND

[0004] The current network energy saving task is discussing the mechanism of terminal on-demand triggering the network to send System Information Block 1 (SIB1) of the energy saving cell. In this scenario, the terminal triggers the energy saving cell to send SIB1 on demand, thereby reducing the number of times of network sending SIB1 to achieve the purpose of energy saving. When the terminal wants to receive SIB1, it can send an uplink wake-up signal to the energy saving cell to notify the cell to send SIB1. Since the terminal needs to know the time-frequency resource information of the uplink wake-up signal in advance, the terminal needs to obtain the configuration information of the uplink wake-up signal from the anchor cell providing basic coverage in advance. That is, the base station with an energy saving cell needs to send the configuration information of the uplink wake-up signal to the base station with an anchor cell in advance, and the specific process is shown in FIG. 1. The current energy saving cell can indicate through the Physical Broadcast Channel (PBCH) in the Synchronization Signal / PBCH Block (SSB) that the SIB1 of the SSB associated cell is triggered on demand.

[0005] When the terminal learns that the SIB1 of the energy saving cell is triggered on demand through the PBCH in the SSB, the learning method can borrow the field indication in the Master Information Block (MIB) message currently carried on the PBCH. However, if the SIB1 of the energy saving cell is indicated as being triggered on demand using the field in the MIB currently carried on the PBCH, the original assignment of the field in the MIB is occupied, affecting the original function of the terminal, thereby causing the problem that the terminal cannot access the energy saving cell. SUMMARY

[0094] In order to make the technical problems, technical solutions and advantages of the present disclosure clearer, the following will be described in detail with reference to the drawings and specific embodiments.

[0095] Firstly, the contents related to the scheme provided by the embodiments of the present application will be introduced.

[0096] The contents contained in the MIB message are as follows:

[0097] The available fields are SSB subcarrier offset (ssb-SubcarrierOffset), pdcch-ConfigSIB1, and cellBarred. cellBarred indicates whether cell access is permitted.

[0098] The ssb-SubcarrierOffset field is used to characterize K. ssb K ssb The meaning is The offset between the subcarrier of the and the subcarrier of the SSB. For the FR1 scenario, K ssb The length is 5 bits, and it needs to be represented by the ssb-SubcarrierOffset field and PBCH. The current value range is 0-23; for the FR2 scenario, K ssb The length is 4 bits, and the value ranges from 0 to 11.

[0099] For frequency range 1 (FR1) and FR2 scenarios, the remaining K bits are 5 or 4 bits. ssb The value can also represent other meanings. For example, when K in the FR1 scene... ssb The value range is 24-29 or K in the FR2 scenario. ssb When the value range is 12-13, it indicates that the current SSB is not associated with SIB1 (Non-Cell-Defining SSB) and has a fixed frequency domain offset from the SSB (Cell-Defining SSB) associated with SIB1. When K in the FR1 scene... ssb The value range of K is 30 or in the FR2 scenario. ssb When the value is 14, this value is not yet used to represent specific content and is called a reserved index value. When K in the FR1 scene... ssb The value range of K is 31 or in the FR2 scenario. ssb When the value is 15, it indicates that the current SSB is not associated with SIB1, and there is no SSB associated with SIB1 in the current SSB's Global Synchronization Channel Number (GSCN).

[0100] pdcch-ConfigSIB1 is used to configure the control resource set CORESET#0 and search space SearchSpace#0, which represents the time-frequency resource location of the Physical Downlink Control Channel (PDCCH) carrying SIB1 scheduling information. The pdcch-ConfigSIB1 field contains the following information:

[0101] Wherein, controlResourceSetZero occupies the high four bytes of pdcch-ConfigSIB1 carried by PBCH, which is used to indicate CORESET#0 information, so as to determine the bandwidth and frequency domain offset of CORESET#0. For each SSB and PDCCH subcarrier spacing, the high 4 bytes have 16 combinations, which can indicate different configuration information, see Table 13-1 shown below. Taking the example that the SSB and PDCCH subcarrier spacing are both 15 kHz and the minimum bandwidth is 5 MHz or 10 MHz, the index value of 15 is a reserved index value.

[0102] Table 13-1: Mapping table of time domain location and resource number of control resource set (CORESET) under the condition that the subcarrier resource blocks of SSB and PDCCH are both 15 kHz and the minimum channel bandwidth is 5 MHz or 10 MHz.

[0103] Table 13-1

[0104] Wherein, searchSpaceZero occupies the low four bytes of pdcch-configSIB1 carried by PBCH, which is used to indicate SearchSpace#0 information, so as to determine the monitoring occasion of Type0-PDCCH. For different multiplexing patterns, frequency band ranges, SSB and PDCCH subcarrier spacing, the low 4 bytes have 16 combinations, which can indicate different configuration information, see Table 13-2 shown below. Taking the example that the SSB and CORESET location follow pattern 1 and the frequency band range is in FR2-1, the index values of 14 and 15 are reserved index values.

[0105] Table 13-12: PDCCH monitoring slot parameter table of Type0-PDCCH common search space under the condition that the multiplexing pattern of SSB and CORESER is 1 in FR2-1, or the multiplexing pattern of SSB and CORESER is 1 and the subcarrier spacing (SCS) is both 120 kHz in FR2-2.

[0106] Table 13-12

[0107] Here, when the terminal learns that the SIB1 of the energy saving cell is triggered on demand through the PBCH indication in the SSB, the learning method can borrow the field indication in the MIB message currently carried on the PBCH.

[0108] For example, the index value reserved in ssb-SubcarrierOffset / current SSB not associated with the index value of SIB1 can be used to indicate that the SIB1 of the cell is triggered on demand.

[0109] The index value reserved in the first 4 bits and / or the last 4 bits of PDCCH-configSIB1 can also be used to indicate that the SIB1 of the cell is triggered on demand.

[0110] The cellBarred value in the MIB can also be set to Barred to indicate that the SIB1 of the cell is triggered on demand.

[0111] However, if the index value reserved in ssb-SubcarrierOffset / current SIB1 not associated with the index value of SIB1 is used to indicate that the SIB1 is triggered on demand, the original function of determining the frequency domain starting position of CORESET#0 cannot be implemented.

[0112] If the index value reserved in the first 4 bits and / or the last 4 bits of PDCCH-configSIB1 is used to indicate that the SIB1 is triggered on demand, the original function of determining the CORESET#0 or searchspace#0 corresponding to the Type0-PDCCH CSS set cannot be implemented.

[0113] If the cellBarred value in the MIB is set to Barred (barred), and the terminal cannot receive the SIB1, the terminal will consider that the cell cannot be accessed.

[0114] That is, if the field in the MIB currently carried on the PBCH is used to indicate that the SIB1 of the energy saving cell is triggered on demand, the original assignment of the field in the MIB is occupied, which affects the terminal to implement the original function, thereby causing the terminal to be unable to access the energy saving cell.

[0115] To solve the above problems, the present disclosure provides a message transmission method, device, storage medium and program product. The method and device are based on the same application concept, and since the principles of solving problems are similar, the implementation of the device and the method can be mutually referred to, and the repeated parts will not be described again.

[0116] As shown in FIG. 2, one of the flowcharts of the message transmission method provided by the embodiments of the present disclosure is shown. The method is applied to a first network device. That is, the method is executed by the first network device. Optionally, the first network device is an energy saving base station or a base station with energy saving capability or a base station including an energy saving cell or a first radio access node with an energy saving cell. The base station can be a 4G or 5G base station, and the first radio access node can be a 4G radio access node or a 5G radio access node. The method specifically comprises:

[0117] In step 201, the second network device is sent the configuration information of the energy-saving cell of the first network device and the terminal identifier.

[0118] Optionally, the second network device comprises a base station with an anchor cell or a second radio access node with an anchor cell, the base station can be a 4G or 5G base station, and the second radio access node can be a 4G radio access node or a 5G radio access node. As an example, the second network device can be an anchor base station. It should be noted that the configuration information is the configuration related to the MIB message of the energy-saving cell, which is used to enable the terminal to normally receive the SIB1 of the energy-saving cell. It should be understood that, after receiving the configuration information of the energy-saving cell and the terminal identifier, the second network device can know which terminals the configuration information of the energy-saving cell corresponds to, i.e., which terminals can use the configuration information of the energy-saving cell, based on the terminal identifier. Wherein, after receiving the configuration information of the energy-saving cell and the terminal identifier, the second network device can send the configuration information of the energy-saving cell of the first network device to the corresponding terminal based on the terminal identifier.

[0119] The configuration information comprises one or more of the following:

[0120] A first configuration parameter; wherein the first configuration parameter is used to determine the time-frequency domain resource of the SIB1. In this way, when the energy-saving cell of the first network device subsequently sends the SSB (wherein a certain (or specific) information element (IE) in the PBCH in the SSB indicates that the SIB1 associated with the SSB is triggered on demand) to the terminal, the terminal receives the SIB1 at the position of the time-frequency domain resource of the SIB1 based on the first configuration parameter.

[0121] An energy-saving cell identifier;

[0122] First time information, the first time information indicates the effective time of the first configuration parameter; or the first time information indicates the transmission time period of the energy-saving cell sending the SSB.

[0123] It should be noted that, in the case where the first time information indicates the effective time of the first configuration parameter, the effective time can be the effective time of the first configuration parameter, at which time the effective time represents that the SSB information sent by the energy-saving cell after the effective time indicates that the energy-saving cell is an on-demand SIB1 cell, or the effective time can be the effective period of the first configuration parameter (i.e., the first configuration parameter is valid in this period), at which time the effective time indicates that after the effective period expires, the configuration of the SSB will be refreshed or invalidated, and the terminal needs to listen to the SSB information of the energy-saving cell within the effective period (i.e., within the effective period).

[0124] The first time information indicates a transmission time period of the SSB transmitted by the energy saving cell, that is, how long the energy saving cell transmits the SSB every time, and the terminal can listen to the SSB in the transmission time period of the SSB.

[0125] The message transmission method of the embodiment of the present disclosure transmits the configuration related to the MIB message of the energy saving cell between network devices in advance, that is, the configuration information of the energy saving cell of the first network device, so as to ensure that the terminal can know the CRB configuration in advance, or the CORESET#0 configuration and / or the search space searchspace#0 configuration, or the cell access indication, so as to be able to normally receive the SIB1, and further enable the terminal to access the energy saving cell.

[0126] In addition, since the configuration related to the MIB message of the energy saving cell is transmitted between network devices in advance, that is, the energy saving base station (the first network device) transmits the configuration related to the MIB message (mainly the resource information containing the SIB1) originally transmitted between the energy saving base station and the terminal to the anchor base station (the second network device) in advance, so that the energy saving base station can adjust the value of the MIB carrying content, and the terminal can know that the SIB1 of the SSB associated cell is triggered on demand after receiving the MIB. It should be understood that since the energy saving base station has already informed the terminal of the resource information corresponding to the SIB1 through the anchor base station in advance, the energy saving base station can use the field in the MIB carried in the PBCH to indicate that the SIB1 of the energy saving cell is triggered on demand, so that the problem that the terminal cannot normally receive the SIB1, and further cannot access the energy saving cell, caused by the fact that the corresponding indication bit is occupied due to the on-demand triggering, and the SIB1 cannot be received through the field in the MIB, will not occur.

[0127] In some embodiments, the first configuration parameter indicates a common resource block (CRB) configuration of the energy saving cell.

[0128] Further, the common resource block (CRB) configuration of the energy saving cell includes:

[0129] the actual K ssb value; or,

[0130] an offset value between the frequency domain starting position of the SSB of the energy saving cell and the frequency domain starting position of the CRB corresponding to the frequency domain starting position of the SSB; or,

[0131] the frequency domain position of the CRB 0 and the subcarrier spacing of the CRB.

[0132] Here, the absolute frequency of the frequency domain position of the CRB 0, i.e., Point A, can be represented by an Absolute Radio Frequency Channel Number (ARFCN) value.

[0133] In some embodiments, the first configuration parameter indicates a control resource set CORESET#0 configuration and / or a search space searchspace#0 configuration of the power saving cell.

[0134] Further, the control resource set CORESET#0 configuration and / or the search space searchspace#0 configuration of the power saving cell comprises:

[0135] The actual physical downlink control channel-system information block 1 configuration PDCCH-configSIB1 value can be a controlResourceSetZero value and / or a searchspaceZero value; or,

[0136] An offset value between the starting position of the CRB where the frequency domain starting position of the power saving cell SSB is located and the frequency domain starting position of the CORESET#0; or,

[0137] An absolute frequency domain position of the CORESET#0 and / or an absolute time domain position of the searchspace#0, such as a duration of the searchspace#0, a period of the searchspace#0 and an offset within the period, and a monitoring symbol within a slot.

[0138] In some embodiments, the first configuration parameter indicates a cell access indication of the power saving cell.

[0139] Further, the cell access indication of the power saving cell comprises a power saving cell barred access or a power saving cell allowed access.

[0140] Specifically, the power saving cell barred access or the power saving cell allowed access can be identified by an actual CellBarred value; or represented by a first field. Optionally, the first field is a barred / not barred field.

[0141] Optionally, there is a mapping relationship between the power saving cell identifier and the first configuration parameter, and the mapping relationship is indicated by the first network device.

[0142] It should be noted that after receiving the power saving cell identifier (carried in the above configuration information) sent by the anchor cell of the anchor base station (the second network device), the terminal learns the corresponding first configuration parameter, so as to access the cell (the power saving cell of the power saving base station) using the set of configurations.

[0143] Herein, the energy saving cell identifier has a mapping relationship with the first configuration parameter, that is, in the scenario of multiple energy saving cells, a specific cell corresponds to a corresponding first configuration parameter.

[0144] In some embodiments, in the case that the configuration information does not include the first configuration parameter, the energy saving cell identifier implicitly indicates one of the following information:

[0145] K of the energy saving cell ssb is a predefined value;

[0146] The frequency domain position and subcarrier spacing of CRB 0 of the energy saving cell are predefined values;

[0147] The high four bits and / or low four bits of PDCCH-ConfigSIB1 of the energy saving cell are predefined values;

[0148] The resource position of CORESET#0 and / or searchspace#0 of the energy saving cell is a predefined value;

[0149] The energy saving cell allows access.

[0150] That is, if the first configuration parameter is not included in the configuration message, the energy saving cell identifier can implicitly indicate that the Kssb value of the energy saving cell is a predefined value / the frequency domain position and subcarrier spacing of CRB 0 is a predefined value / the high four bits and / or low four bits of PDCCH-ConfigSIB1 of the energy saving cell are predefined values / the resource position of CORESET#0 and / or searchspace#0 is a predefined value / indicating that the energy saving cell allows access.

[0151] In an optional embodiment, the above step 201 comprises:

[0152] The second network device sends the configuration information of the uplink wake-up signal to the terminal, wherein the configuration information of the uplink wake-up signal comprises the configuration information of the energy saving cell of the first network device and the terminal identifier.

[0153] The message transmission method of the embodiments of the present disclosure transmits the configuration information of the energy-saving cell of the first network device and the terminal identifier to the second network device, wherein the configuration information comprises one or more of the following: a first configuration parameter used to determine the time-frequency domain resource of a system information block (SIB1); an energy-saving cell identifier; first time information indicating the effective time of the first configuration parameter; or the first time information indicating the transmission time period of the energy-saving cell transmitting an SSB. In this way, the configuration related to the MIB message of the energy-saving cell is transmitted in advance between network devices, so as to ensure that the terminal can learn the CRB configuration, or the CORESET#0 configuration and / or the search space#0 configuration, or the cell access indication in advance, thereby being able to normally receive the SIB1, and further enabling the terminal to access the energy-saving cell.

[0154] As shown in FIG. 3, it is a second flowchart of the message transmission method provided by the embodiments of the present disclosure. The method is applied to a second network device. That is, the method is executed by the second network device. Optionally, the second network device is an anchor base station. The method specifically comprises the following steps:

[0155] In step 301, the configuration information of the energy-saving cell of the first network device and the terminal identifier transmitted by the first network device are received.

[0156] Optionally, the first network device is an energy-saving base station or a base station with energy-saving capability. It should be noted that the configuration information is the configuration related to the MIB message of the energy-saving cell, which is used to enable the terminal to normally receive the SIB1 of the energy-saving cell. It should be understood that, after receiving the configuration information of the energy-saving cell and the terminal identifier, the second network device can learn which terminals the configuration information of the energy-saving cell corresponds to, i.e., which terminals can use the configuration information of the energy-saving cell, based on the terminal identifier. Wherein, after receiving the configuration information of the energy-saving cell and the terminal identifier, the second network device can transmit the configuration information of the energy-saving cell of the first network device to the corresponding terminal based on the terminal identifier.

[0157] The configuration information comprises one or more of the following:

[0158] a first configuration parameter, wherein the first configuration parameter is used to determine the time-frequency domain resource of the SIB1. In this way, when the energy-saving cell of the first network device transmits the SSB to the terminal subsequently (wherein a certain (or specific) IE in the PBCH in the SSB indicates that the SIB1 associated with the SSB is triggered on demand), the terminal receives the SIB1 at the position of the time-frequency domain resource of the SIB1 based on the first configuration parameter

[0159] an energy-saving cell identifier;

[0160] The first time information indicates an effective time of the first configuration parameter, or the first time information indicates a transmission time period of SSB transmission of the energy saving cell.

[0161] It should be noted that, in the case where the first time information indicates the effective time of the first configuration parameter, the effective time can be an effective time point of the first configuration parameter, at which time the effective time represents that the SSB information transmitted by the energy saving cell after the effective time point indicates that the energy saving cell is an on-demand SIB1 cell, or the effective time can be an effective time period of the first configuration parameter (i.e., the first configuration parameter is valid in this period), at which time the effective time indicates that after the effective time period expires, the configuration of the SSB will be refreshed or invalidated, and the terminal needs to listen to the SSB information of the energy saving cell within the effective time period (i.e., within the effective time period).

[0162] The first time information indicates a transmission time period of SSB transmission of the energy saving cell, i.e., how long the energy saving cell transmits SSB every time, and the terminal can listen to SSB within the transmission time period of SSB.

[0163] The message transmission method of the embodiments of the present disclosure receives the configuration information of the energy saving cell of the first network device and the terminal identifier sent by the first network device, wherein the configuration information includes one or more of the following: the first configuration parameter, which is used to determine the time-frequency domain resource of the system information block SIB1; the energy saving cell identifier; the first time information, which indicates the effective time of the first configuration parameter; or the first time information indicates a transmission time period of SSB transmission of the energy saving cell. In this way, the configuration related to the MIB message of the energy saving cell is transmitted in advance between network devices, so as to ensure that the terminal can know the CRB configuration, or the CORESET#0 configuration and / or the search space#0 configuration, or the cell access indication in advance, so as to be able to normally receive SIB1, and further enable the terminal to access the energy saving cell.

[0164] In addition, since the configuration related to the MIB message of the energy saving cell is transmitted in advance between network devices, i.e., the energy saving base station (the first network device) transmits the configuration related to the MIB message (mainly including the resource information of SIB1) originally transmitted between the energy saving base station and the terminal to the anchor base station (the second network device), so that the energy saving base station can adjust the assignment of the MIB carrying content, and the terminal can know that the SIB1 of the SSB associated cell is triggered on demand after receiving the MIB.

[0165] In some embodiments, the first configuration parameter indicates the common resource block CRB configuration of the energy saving cell.

[0166] Further, the common resource block, CRB, configuration of the energy saving cell comprises:

[0169] a frequency domain position of the CRB 0 and a subcarrier spacing of the CRB.

[0170] Here, the frequency domain position of the CRB 0 is the absolute frequency of the Point A, and the absolute frequency value can be represented by the Absolute Radio Frequency Channel Number (ARFCN).

[0171] In some embodiments, the first configuration parameter indicates a control resource set, CORESET, #0 configuration and / or a search space, searchspace, #0 configuration of the energy saving cell.

[0176] In some embodiments, the first configuration parameter indicates a cell access indication of the energy saving cell.

[0177] Further, the cell access indication of the energy saving cell comprises that the energy saving cell prohibits access or the energy saving cell allows access.

[0179] Optionally, the energy saving cell identifier has a mapping relationship with the first configuration parameter, and the mapping relationship is indicated by the first network device.

[0180] It should be noted that when the terminal receives the energy saving cell identifier (carried in the above configuration information) sent by the anchor cell of the anchor base station (the second network device), the terminal learns the corresponding first configuration parameter, so as to select the set of configuration to access the cell (the energy saving cell of the energy saving base station).

[0181] Here, the energy saving cell identifier has a mapping relationship with the first configuration parameter, that is, in the scenario of multiple energy saving cells, a specific cell corresponds to the corresponding first configuration parameter.

[0182] In some embodiments, in the case that the configuration information does not include the first configuration parameter, the energy saving cell identifier implicitly indicates one of the following information:

[0183] K of the energy saving cell ssb is a predefined value;
