Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a message transmission method, device, storage medium, and program product. Background Technology

[0002] Current network energy conservation research is discussing the mechanism of on-demand triggering of System Information Block 1 (SIB1) transmission by the terminal. In this scenario, the terminal triggers the energy-saving cell to transmit SIB1 on demand, thereby reducing the number of times the network transmits SIB1 and achieving energy conservation. When the terminal wants to receive SIB1, it can send an uplink wake-up signal to the energy-saving cell to notify it to transmit SIB1. Since the terminal needs to know the time-frequency resource information for transmitting the uplink wake-up signal in advance, it 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 the energy-saving cell needs to send the configuration information of the uplink wake-up signal to the base station with the anchor cell in advance. The specific process is as follows: Figure 1 As shown. Currently, energy-saving cells can indicate that SIB1 of the SSB-associated cell is triggered on demand through the Physical Broadcast Channel (PBCH) in the Synchronization Signal / PBCH Block (SSB).

[0003] When a terminal learns that the SIB1 of an energy-saving cell is triggered on demand via the PBCH indication in the SSB, this information can be obtained by using a field indication from the Master Information Block (MIB) message currently carried on the PBCH. However, if the field indication from 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 value of the field in the MIB is occupied, affecting the terminal's original functions and causing the terminal to be unable to access the energy-saving cell. Summary of the Invention

[0092] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0093] The following section will first introduce the content related to the solutions provided in the embodiments of this application.

[0094] The MIB message contains the following content:

[0095]

[0096]

[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]

[0102] The `controlResourceSetZero` parameter occupies the high four bytes of `pdcch-ConfigSIB1` carried by the PBCH, used to indicate the CORESET#0 information, thereby determining the bandwidth and frequency offset of CORESET#0. For each SSB and PDCCH subcarrier spacing, the high four bytes have 16 combinations that can indicate different configuration information, as shown in Table 13-1 below. Taking an SSB and PDCCH subcarrier spacing of 15kHz and a minimum bandwidth of 5MHz or 10MHz as an example, the index value 15 is a reserved index value.

[0103] Table 13-1: Mapping table of time-domain location and number of resources of control-resource set (CORESET) under the condition that the subcarrier resource blocks of SSB and PDCCH are both 15kHz and the minimum channel bandwidth is 5MHz or 10MHz.

[0104]

[0105] The `searchSpaceZero` parameter occupies the lower four bytes of `pdcch-configSIB1` carried by the PBCH, used to indicate the `SearchSpace#0` information, thereby determining the listening timing of the Type 0-PDCCH. For different multiplexing patterns, frequency bands, and subcarrier spacing of the SSB and PDCCH, the lower four bytes can have a total of 16 combinations to indicate different configuration information, as shown in Table 13-2 below. Taking SSB and CORESET positions following pattern 1 and frequency band FR2-1 as an example, index values ​​14 and 15 are reserved index values.

[0106] Table 13-12: PDCCH listening slot parameters of the Type 0-PDCCH common search space under the condition that the multiplexing pattern of FR2-1, SSB and CORESER is 1, or the multiplexing pattern of FR2-2, SSB and CORESER is 1 and the sub-carrier spacing (SCS) is 120kHz.

[0107]

[0108] 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 method of learning can be borrowed from the field indication in the MIB message currently carried on the PBCH.

[0109] For example, the index value reserved in ssb-SubcarrierOffset / the index value of the current SSB not associated with SIB1 can be used to indicate that the SIB1 of this cell is triggered on demand.

[0110] The reserved index value in the first 4 bits and / or last 4 bits of PDCCH-configSIB1 can also be used to indicate that the SIB1 of the cell is triggered on demand.

[0111] Alternatively, setting the cellBarred value in the MIB to Barred indicates that SIB1 for that cell is triggered on demand.

[0112] However, if SSB-subcarrierOffset is used, the reserved index value / the index value of the current SSB that is not associated with SIB1 is used to instruct SIB1 to trigger on demand, which will make the original function of determining the starting position of CORESET#0 frequency domain impossible.

[0113] If the index value reserved in the first 4 bits and / or last 4 bits of PDCCH-configSIB1 is used to instruct SIB1 to be triggered on demand, the original function of determining the CORESET#0 or searchspace#0 corresponding to the Type0-PDCCH CSS set will not be able to be implemented.

[0114] If the cellBarred value in the MIB is set to Barred (disabled), and the terminal cannot receive SIB1, the terminal will think that the cell cannot be accessed.

[0115] In other words, 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 value of the field in the MIB will be occupied, affecting the terminal's original function and causing the terminal to be unable to access the energy-saving cell.

[0116] To address the aforementioned problems, this invention provides a message transmission method, apparatus, storage medium, and program product. The method and apparatus are based on the same concept, and since the principles underlying the problems solved by the method and apparatus are similar, their implementations can be referred to interchangeably; repeated details will not be elaborated further.

[0117] like Figure 2The diagram shown is one of the flowcharts illustrating a message transmission method provided in an embodiment of the present invention. This 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 capabilities. Specifically, the method includes:

[0118] Step 201: Send the configuration information and terminal identifier of the energy-saving cell of the first network device to the second network device.

[0119] Optionally, the second network device is an anchor base station. It should be noted that the configuration information is related to the MIB message of the energy-saving cell, 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 determine which terminals correspond to the configuration information of the energy-saving cell, i.e., which terminals can utilize the configuration information of the energy-saving cell, based on the terminal identifier. Furthermore, 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.

[0120] The configuration information includes one or more of the following:

[0121] The first configuration parameter is used to determine the time-frequency domain resources of SIB1. Thus, when the energy-saving cell of the first network device subsequently sends an SSB to the terminal (wherein a certain (or specific) Information Element (IE) in the PBCH of the SSB indicates that the SIB1 associated with the SSB is triggered on demand), the terminal receives the SSB1 at the location of the time-frequency domain resources of SIB1 based on the first configuration parameter.

[0122] Energy-saving community signage;

[0123] 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 SSB.

[0124] It should be noted that when the first time information indicates the effective time of the first configuration parameter, the effective time can be the effective moment of the first configuration parameter. In this case, the effective time indicates that the SSB information sent by the energy-saving cell after the effective moment will indicate that the energy-saving cell is a cell that triggers SIB1 (on-demand SIB1). Alternatively, the effective time can be the effective period of the first configuration parameter (i.e., the first configuration parameter is valid during this period). In this case, the effective time indicates that after the effective period expires, the SSB configuration will be refreshed or invalidated, and the terminal needs to listen to the SSB information of the energy-saving cell before the effective period expires (i.e., within the effective period).

[0125] The first-time information indicates the transmission period of the SSB sent by the energy-saving cell, that is, how often the energy-saving cell sends an SSB, and the terminal can listen for the SSB within the transmission period.

[0126] The message transmission method of this invention transmits configuration related to the MIB message of the energy-saving cell between network devices in advance, namely the configuration information of the energy-saving cell of the first network device, thereby ensuring that the terminal can know the CRB configuration, or CORESET#0 configuration and / or searchspace#0 configuration, or cell access indication in advance, so as to receive SIB1 normally and enable the terminal to access the energy-saving cell.

[0127] Furthermore, because the network devices transmit configurations related to the MIB messages of the energy-saving cell in advance—that is, the energy-saving base station (the first network device) sends the configurations of the MIB messages (mainly including resource information of SIB1) that were originally transmitted between the energy-saving base station and the terminal to the anchor base station (the second network device) in advance—the energy-saving base station can adjust the values ​​assigned to the MIB bearer content. Upon receiving the MIB, the terminal can then know that the SIB1 of the SSB-associated cell is triggered on demand. It should be understood that since the energy-saving base station has already informed the terminal of the resource information corresponding to SIB1 in advance through the anchor base station, the energy-saving base station can use the fields in the MIB carried on the PBCH in the SSB to indicate that the SIB1 of the energy-saving cell is triggered on demand. This avoids the problem of the terminal being unable to receive SIB1 due to the on-demand trigger indicator bit being occupied, thus preventing the terminal from accessing the energy-saving cell.

[0128] In some embodiments, the first configuration parameter indicates the Common Resource Block (CRB) configuration of the energy-saving cell.

[0129] Furthermore, the configuration of the Common Resource Block (CRB) in the energy-saving community includes:

[0130] The actual K ssb Value; or,

[0131] The offset between the frequency domain starting position of the SSB in the energy-saving community and the frequency domain starting position of the corresponding CRB; or,

[0132] The frequency domain position of CRB 0 and the subcarrier spacing of CRB.

[0133] Here, the frequency domain position of CRB 0 is the absolute frequency of Point A, which can be represented by the Absolute Radio Frequency Channel Number (ARFCN).

[0134] In some embodiments, the first configuration parameter indicates the configuration of the control resource set CORESET#0 and / or the search space #0 of the energy-saving cell.

[0135] Furthermore, the control resource set CORESET#0 configuration and / or searchspace#0 configuration of the energy-saving community include:

[0136] The actual physical downlink control channel - system information block 1 configuration PDCCH-configSIB1 value can be the controlResourceSetZero value and / or the searchspaceZero value; or,

[0137] The offset between the starting position of the frequency domain of the energy-saving community SSB and the starting position of the CRB, and the starting position of the frequency domain of CORESET#0; or,

[0138] The absolute frequency domain position of CORESET#0 and / or the absolute time domain position of searchspace#0, such as the duration of searchspace#0, the period of searchspace#0 and the offset within the period, and the listening symbols within the time slot.

[0139] In some embodiments, the first configuration parameter indicates a cell access indication for an energy-saving cell.

[0140] Furthermore, the access indication for the energy-saving community includes whether access is prohibited or permitted in the energy-saving community.

[0141] Specifically, whether access is prohibited or permitted in an energy-saving community can be identified by the actual CellBarred value; or by the first field. Optionally, the first field is a barred / not barred field.

[0142] Optionally, there is a mapping relationship between the energy-saving community identifier and the first configuration parameter, and the mapping relationship is indicated by the first network device.

[0143] 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 (second network device), the terminal learns the corresponding first configuration parameters and thus selects the configuration to access the cell (energy-saving cell of the energy-saving base station).

[0144] Here, there is a mapping relationship between the energy-saving community identifier and the first configuration parameter. That is, in the scenario of multiple energy-saving communities, a specific community corresponds to the corresponding first configuration parameter.

[0145] In some embodiments, when the configuration information does not include the first configuration parameter, the energy-saving cell identifier implicitly indicates one of the following:

[0146] K of the energy-saving community ssb The value is a predefined value;

[0147] The frequency domain position and subcarrier spacing of CRB 0 in the energy-saving community are predefined values;

[0148] The high four bits and / or low four bits of PDCCH-configSIB1 in the energy-saving community are predefined values;

[0149] The resource locations of CORESET#0 and / or searchspace#0 in the energy-saving community are predefined values;

[0150] Energy-efficient communities are permitted to connect.

[0151] That is, if the configuration message does not contain the first configuration parameter, 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 are predefined values ​​ / the high 4 bits and / or low 4 bits of the energy-saving cell PDCCH-ConfigSIB1 are predefined values ​​ / the resource position of CORESET#0 and / or searchspace#0 is a predefined value / indicating that the energy-saving cell is allowed to access.

[0152] In an optional embodiment, step 201 above includes:

[0153] Configuration information for sending an uplink wake-up signal to a second network device, wherein the configuration information for the uplink wake-up signal includes the configuration information of the energy-saving cell of the first network device and the terminal identifier.

[0154] The message transmission method of this invention transmits the configuration information of the energy-saving cell of the first network device and the terminal identifier to the second network device. The configuration information includes one or more of the following: a first configuration parameter used to determine the time-frequency domain resources of the 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 for the energy-saving cell to send SSBs. By transmitting configurations related to the MIB message of the energy-saving cell between network devices in advance, the terminal can be guaranteed to know the CRB configuration, or the CORESET#0 configuration and / or the searchspace#0 configuration, or the cell access indication in advance, thereby enabling it to receive SIB1 normally and access the energy-saving cell.

[0155] like Figure 3 The diagram shown is a second flowchart illustrating the message transmission method provided in this embodiment of the invention. This 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. Specifically, the method includes:

[0156] Step 301: Receive the configuration information of the energy-saving cell of the first network device and the terminal identifier sent by the first network device.

[0157] Optionally, the first network device is an energy-saving base station or a base station with energy-saving capabilities. It should be noted that the configuration information is related to the MIB message of the energy-saving cell, 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 determine which terminals correspond to the configuration information of the energy-saving cell, i.e., which terminals can utilize the configuration information of the energy-saving cell, based on the terminal identifier. Furthermore, 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 first network device's energy-saving cell to the corresponding terminal based on the terminal identifier.

[0158] The configuration information includes one or more of the following:

[0159] The first configuration parameter is used to determine the time-frequency domain resources of SIB1. Thus, when the energy-saving cell of the first network device subsequently sends an SSB to the terminal (wherein a certain IE in the PBCH of the SSB indicates that the SIB1 associated with the SSB is triggered on demand), the terminal receives the SSB1 at the location of the time-frequency domain resources of SIB1 based on the first configuration parameter.

[0160] Energy-saving community signage;

[0161] 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 SSB.

[0162] It should be noted that when the first time information indicates the effective time of the first configuration parameter, the effective time can be the effective moment of the first configuration parameter. In this case, the effective time indicates that the SSB information sent by the energy-saving cell after the effective moment will indicate that the energy-saving cell is a cell that triggers SIB1 (on-demand SIB1). Alternatively, the effective time can be the effective period of the first configuration parameter (i.e., the first configuration parameter is valid during this period). In this case, the effective time indicates that after the effective period expires, the SSB configuration will be refreshed or invalidated, and the terminal needs to listen to the SSB information of the energy-saving cell before the effective period expires (i.e., within the effective period).

[0163] The first-time information indicates the transmission period of the SSB sent by the energy-saving cell, that is, how often the energy-saving cell sends an SSB, and the terminal can listen for the SSB within the transmission period.

[0164] The message transmission method of this invention receives configuration information of the energy-saving cell of a first network device and a terminal identifier sent by a first network device. The configuration information includes one or more of the following: a first configuration parameter used to determine the time-frequency domain resources of 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 for the energy-saving cell to send SSBs. By transmitting configuration related to the MIB message of the energy-saving cell between network devices in advance, the terminal can be guaranteed to know the CRB configuration, or the CORESET#0 configuration and / or the searchspace#0 configuration, or the cell access indication in advance, thereby enabling it to receive SIB1 normally and access the energy-saving cell.

[0165] In addition, because the network devices transmit the configuration related to the MIB message of the energy-saving cell in advance, that is, the energy-saving base station (the first network device) sends the configuration of the MIB message (mainly including the resource information of SIB1) that was originally transmitted between the energy-saving base station and the terminal to the anchor base station (the second network device) in advance, the energy-saving base station can adjust the value of the MIB bearer content, and the terminal can know that the SIB1 of the SSB associated cell is triggered on demand after receiving the MIB.

[0166] In some embodiments, the first configuration parameter indicates the Common Resource Block (CRB) configuration of the energy-saving cell.

[0167] Furthermore, the configuration of the Common Resource Block (CRB) in the energy-saving community includes:

[0168] The actual K ssb Value; or,

[0169] The offset between the frequency domain starting position of the SSB in the energy-saving community and the frequency domain starting position of the corresponding CRB; or,

[0170] The frequency domain position of CRB 0 and the subcarrier spacing of CRB.

[0171] Here, the frequency domain position of CRB 0 is the absolute frequency of Point A, which can be represented by the Absolute Radio Frequency Channel Number (ARFCN).

[0172] In some embodiments, the first configuration parameter indicates the configuration of the control resource set CORESET#0 and / or the search space #0 of the energy-saving cell.

[0173] Furthermore, the control resource set CORESET#0 configuration and / or searchspace#0 configuration of the energy-saving community include:

[0174] The actual physical downlink control channel - system information block 1 configuration PDCCH-configSIB1 value can be the controlResourceSetZero value and / or the searchspaceZero value; or,

[0175] The offset between the starting position of the frequency domain of the energy-saving community SSB and the starting position of the CRB, and the starting position of the frequency domain of CORESET#0; or,

[0176] The absolute frequency domain position of CORESET#0 and / or the absolute time domain position of searchspace#0, such as the duration of searchspace#0, the period of searchspace#0 and the offset within the period, and the listening symbols within the time slot.

[0177] In some embodiments, the first configuration parameter indicates a cell access indication for an energy-saving cell.

[0178] Furthermore, the access indication for the energy-saving community includes whether access is prohibited or permitted in the energy-saving community.

[0179] Specifically, whether access is prohibited or permitted in an energy-saving community can be identified by the actual CellBarred value; or by the first field. Optionally, the first field is a barred / not barred field.

[0180] Optionally, there is a mapping relationship between the energy-saving community identifier and the first configuration parameter, and the mapping relationship is indicated by the first network device.

[0181] 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 (second network device), the terminal learns the corresponding first configuration parameters and thus selects the configuration to access the cell (energy-saving cell of the energy-saving base station).

[0182] Here, there is a mapping relationship between the energy-saving community identifier and the first configuration parameter. That is, in the scenario of multiple energy-saving communities, a specific community corresponds to the corresponding first configuration parameter.

[0183] In some embodiments, when the configuration information does not include the first configuration parameter, the energy-saving cell identifier implicitly indicates one of the following:

[0184] K of the energy-saving community ssb The value is a predefined value;

[0185] The frequency domain position and subcarrier spacing of CRB 0 in the energy-saving community are predefined values;

[0186] The high four bits and / or low four bits of PDCCH-configSIB1 in the energy-saving community are predefined values;

[0187] The resource locations of CORESET#0 and / or searchspace#0 in the energy-saving community are predefined values;

[0188] Energy-efficient communities are permitted to connect.

[0189] That is, if the configuration message does not contain the first configuration parameter, 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 are predefined values ​​ / the high 4 bits and / or low 4 bits of the energy-saving cell PDCCH-ConfigSIB1 are predefined values ​​ / the resource position of CORESET#0 and / or searchspace#0 is a predefined value / indicating that the energy-saving cell is allowed to access.

[0190] In an optional embodiment, step 301 above includes:

[0191] The configuration information for receiving the uplink wake-up signal sent by the first network device includes the configuration information of the energy-saving cell of the first network device and the terminal identifier.

[0192] In an optional embodiment, the method further includes:

[0193] Based on the terminal identifier, the configuration information of the energy-saving cell of the first network device is sent to the terminal corresponding to the terminal identifier. In this way, the terminal can know the CRB configuration, or CORESET#0 configuration and / or searchspace#0 configuration, or cell access indication in advance based on the configuration information of the energy-saving cell of the first network device, so as to receive SIB1 normally and thus enable the terminal to access the energy-saving cell.
