Description

Resource indication method, terminal and network equipment

Technical Field

The present application relates to the field of mobile communications technologies, and in particular, to a resource indication method, a terminal, and a network device.

Background

In order to meet the demands of partial use cases of the internet of things, such as industrial wireless sensor networks, smart cities and wearable devices, the capacity-reducing (Reduced Capability, redCap) terminal reduces the complexity and cost of the terminal by reducing the bandwidth, the number of receiving and transmitting antennas, the processing capacity of the terminal and the like. The RedCap terminal considers that the control resource set (Control resource set, CORESET) and system information block 1 (System Information Block 1, sib1) reception of the type0 physical downlink control channel (type 0 Physical Downlink Control Channel, type 0-PDCCH) should be limited to within 5MHz, reducing the maximum bandwidth to 5 MHz.

In the prior art, in a cell search stage in a New Radio, NR, when a UE determines from a MIB message that there is a CORESET transmitting Type0-PDCCH CSS, the number of Resource positions of a continuous (RB) Resource Block of the CORESET is determined by the upper four bits of the pdfch-ConfigSIB 1 information in a master information Block (Master Information Block, MIB), and the number of symbols is continued. Table 1 is an example of a configuration table (the table is also referred to as CORESET0 configuration table in the present application), and different configuration tables are corresponding to different subcarrier spacing combinations of { SSB, PDCCH }, and different minimum channel bandwidths.

Under various configurations, the minimum RB number of CORESET is 24. According to subcarrier spacing and RB numberThe bandwidth of CORESET can be determined, +.>The number of symbols of CORESET is determined. Wherein the offset value (offset) indicates the number of RBs offset between the lowest physical resource block (Physical Resource Block, PRB) position of the synchronization signal block (Synchronization Signal and PBCH block, SSB) and the lowest PRB position of the Type-0 PDCCH CORESET.

TABLE 1

The UE determines the slot position (listening occasion monitoring occasions) of the detected PDCCH by the lowest 4 bits of the PDCCH-ConfigSIB 1. The parameters of the PDCCH detection time slot determined by 16 states of 4 bits are determined by tables, according to different frequency ranges (frequency ranges), different multiplexing patterns (multiplexing pattern) of SSB and CORESET, different subcarrier spacing combinations of SSB and PDCCH, and different corresponding tables, and table 2 gives one example of PDCCH monitoring opportunity parameters under multiplexing patterns 1 and FR1 of SSB and CORESET.

TABLE 2

In table 2, O represents an offset value of a slot in which a listening occasion of a different subcarrier interval is located, and M represents a density of the listening occasions.

For SSB and CORESET multiplexing mode 1, the UE monitors a TypeO-PDCCH corresponding to the detected SSB with a fixed period of 20 ms. The listening radio frames corresponding to a certain SSB may be configured in odd or even frames, depending onI represents the SSB index (SSB index). When M _frame If even, the listening occasion is placed in an even frame; when M _frame When odd, the listening occasion is placed in an odd frame. Each listening radio frame contains two consecutive listening slots, and the network is free to place the PDCCH associated with the SSB in either of two consecutive time periods, so the UE must listen to both consecutive slots. Monitoring the starting position of a time slot

After the UE monitors the TypeO-PDCCH, the frequency domain resource of the SIB1 scheduled by the TypeO-PDCCH is indicated by a DCI 1_0 Frequency domain resource assignment domain, the time domain resource is indicated by Time domain resource assignment bits, and the corresponding default PDSCH TDRA table is as follows, and the existing SIB1 scheduling is the simultaneous slot scheduling.

TABLE 3 Table 3

According to the existing protocol, the CORESET0 and SIB1 of legacy terminals may be larger than 5mhz, and it is difficult for r18redcap to multiplex the existing CORESET0 and SIB1 designs, requiring new CORESET and default PDSCH TDRAtable tables of type 0-PDCCH.

Referring to fig. 1, fig. 1 is a block diagram of a wireless communication system to which an embodiment of the present application is applicable. The wireless communication system includes a terminal 11 and a network device 12. The terminal 11 may also be referred to as a User terminal or a User Equipment (UE), and the terminal 11 may be a terminal-side Device such as a mobile phone, a tablet Computer (Tablet Personal Computer), a Laptop (Laptop Computer), a personal digital assistant (Personal Digital Assistant, PDA), a mobile internet Device (Mobile Internet Device, MID), a Wearable Device (Wearable Device), or a vehicle-mounted Device, which is not limited to a specific type of the terminal 11 in the embodiment of the present application. The network device 12 may be a base station and/or a core network element, where the base station may be a 5G or later version base station (e.g., a gNB, a 5G NR NB, etc.), or a base station in another communication system (e.g., an eNB, a WLAN access point, or other access points, etc.), where the base station may be referred to as a node B, an evolved node B, an access point, a base transceiver station (Base Transceiver Station, a BTS), a radio base station, a radio transceiver, a basic service set (Basic Service Set, BSS), an extended service set (Extended Service Set, ESS), a node B, an evolved node B (eNB), a home node B, a home evolved node B, a WLAN access point, a WiFi node, or some other suitable terminology in the field, and the base station is not limited to a specific technical vocabulary, and in the embodiment of the present application, the base station in the NR system is merely an example, but is not limited to a specific type of the base station.

The base stations may communicate with the terminal 11 under the control of a base station controller, which may be part of the core network or some base stations in various examples. Some base stations may communicate control information or user data with the core network over a backhaul. In some examples, some of these base stations may communicate with each other directly or indirectly over a backhaul link, which may be a wired or wireless communication link. A wireless communication system may support operation on multiple carriers (waveform signals of different frequencies). A multicarrier transmitter may transmit modulated signals on the multiple carriers simultaneously. For example, each communication link may be a multicarrier signal modulated according to various radio technologies. Each modulated signal may be transmitted on a different carrier and may carry control information (e.g., reference signals, control channels, etc.), overhead information, data, and so on.

The base station may communicate wirelessly with the terminal 11 via one or more access point antennas. Each base station may provide communication coverage for a respective corresponding coverage area.

Downlink transmissions may be made using licensed bands, unlicensed bands, or both. Similarly, uplink transmissions may be made using licensed bands, unlicensed bands, or both.

The embodiment of the application provides a resource indication method which can realize the type0-PDCCH CORESET configuration of different types of terminals. Further, the embodiment of the application can realize the configuration under the condition of maximally multiplexing the existing PBCH and DCI 1_0 information bits. Furthermore, the embodiment of the application can realize the configuration of the monitoring time (monitoring occasion) and the default PDSCH (default PDSCH) time domain resource configuration of different types of terminals. In the embodiment of the application, at least two types of terminals are introduced, one classification mode of different terminals can be a bandwidth range supported by the terminals, and the terminals are divided into different types of terminals according to the interval of the bandwidth range divided in advance. The at least two classes include a first class of terminals and a second class of terminals. Wherein the maximum bandwidth of the first class of terminals is smaller than the maximum bandwidth of the second class of terminals. For example, the first type of terminal may be a RedCap terminal (also referred to herein as a RedCap terminal or a 5MHz RedCap terminal, with a bandwidth within 5 MHz), and the second type of terminal may be a legacy terminal (also referred to herein as a legacy terminal, with a bandwidth typically greater than 5 MHz). For convenience of description, the type0-PDCCH CORESET is also abbreviated as CORESET0 in the present application, and in the description of the two types, the CORESET of the type0-PDCCH of the 5MHz RedCAP terminal is abbreviated as 5MHz CORESET0, and the CORESET of the type0-PDCCH of the legacy terminal is abbreviated as legacy CORESET0.

Referring to fig. 2, when applied to a terminal side, a resource indication method provided by an embodiment of the present application includes:

step 201, receiving PDCCH configuration information sent by a network, wherein the PDCCH configuration information includes first indication information for Type-0 PDCCH control resource set CORESET.

Here, the PDCCH configuration information may be carried in a MIB message, for example, pdfch-ConfigSIB 1 information carried in the MIB. The pdcch-ConfigSIB1 information generally has 8 bits, and specifically, the first indication information may be the upper four bits of the pdcch-ConfigSIB1 information, i.e., the top 4 bits.

Step 202, determining first resource location information according to the resource block and symbol set information of the first control resource set and the first indication information, to obtain a resource location where the control resource set is located, where the resource block and symbol set information of the first control resource set is the resource block and symbol set information of the control resource set corresponding to the first class terminal to which the first terminal belongs, and the resource block and symbol set information of the corresponding control resource set is set for different classes of terminals.

In the embodiment of the application, the resource block and symbol set information of the corresponding control resource set are set for the terminals of different terminal types, and the resource block and symbol set information of the control resource set is used for indicating the resource position of the control resource set of the terminal. The resource block and symbol set information of the control resource sets corresponding to the various terminals may be predefined or network configured. In particular, the resource block and symbol set information for the control resource set may be information in a CORESET0 configuration table similar to that shown in table 1.

Through the steps, the embodiment of the application can realize the type0-PDCCH CORESET configuration of different types of terminals.

In the embodiment of the present application, the first indication information may be a first field in the PDCCH configuration information, for example, the upper four bits in the PDCCH-ConfigSIB1 information. In step 202, the first terminal may determine the first resource location information from the resource block and symbol set information of the first control resource set with the value of the first field as an index.

The resource block and time slot symbol set information of the first control resource set includes at least one combination, each combination corresponding to a value of the first indication information. Each combination may specifically include at least one parameter of an RB number, a symbol number, and a first offset value, where the first offset value represents an offset between a minimum RB index of a control resource set of a Type-0PDCCH to a common RB index overlapping with an SSB minimum RB, or between a minimum RB index of a control resource set of a Type-0PDCCH to a minimum RB index of a control resource set of a Type-0PDCCH of a second Type terminal, or between a minimum RB index of a control resource set of a Type-0PDCCH to a maximum RB index of a control resource set of a Type-0PDCCH of the second Type terminal.

In this way, the embodiment of the application realizes that the CORESET0 configuration (for example, the legacy CORESET0 and 5mhz CORESET0 configuration) of different types of terminals is indicated simultaneously under the condition of not increasing the bit number by configuring the CORESET configuration table of the high four bits of the PDCCH-ConfigSIB1 and the reconfiguration type 0-PDCCH. The following description will be given by taking a 5MHz RedCap terminal and a legacy terminal as examples of the first type terminal and the second type terminal, respectively.

The CORESET0 configuration table of the first type of terminal (e.g., 5MHz RedCap terminal) includes SSB and CORESET multiplexing mode, RB number of CORESET, symbol number, and frequency domain offset value offset (first offset value). Because of the smaller number of RBs at 5MHz, in order to support higher aggregation levels, embodiments of the present application extend the number of symbols at 5MHz CORESET0 from a maximum of 3 to a maximum of N, N being greater than 3 in table 1.

The first offset value (frequency domain offset) means an offset from a minimum RB index of 5mhz CORESET0 to a common RB index overlapping with the SSB minimum RB, or an offset from a minimum RB index of 5mhz CORESET0 to a minimum RB index of legacy CORESET0, or an offset from a minimum RB index of 5mhz CORESET0 to a maximum RB index of legacy CORESET0. Specifically, the value of the first offset value (frequency domain offset) may be as follows:

(1) The first is that 5MHz CORESET0 overlaps with the CD-SSB frequency domain. At this time, the first offset value of 5MHz CORESET0 is 0 or more and is equal to or less than the difference between the number of 5MHz CORESET0 RBs and the number of cell definition SSB (CD-SSB) RBs.

(2) The second is that 5MHz CORESET0 does not overlap with legacy CORESET0, CD-SSB frequency domains. When the first offset value is positive and smaller than the CD-SSB start RB number, the 5MHz CORESET0 is offset downwards relative to the legacy CORESET0 frequency domain, the offset of the 5MHz CORESET0 is larger than or equal to the sum of the first offset value of the legacy CORESET0 and the 5MHz CORESET0 RB number or larger than or equal to the 5MHz CORESET0 RB number. When the first offset value is negative and the absolute value is greater than or equal to the RB number of legacy CORESET0 minus the first offset value or absolute value of legacy CORESET0 is greater than or equal to 0,5MHz CORESET0 is offset upward relative to the legacy CORESET0 frequency domain.

Table 4 shows an example of a CORESET0 configuration table in an embodiment of the present application, where the Index (Index) of the first column is the CORESET0 Index, the second column represents the SSB multiplexing pattern with CORESET0, the third column to the fifth column are the second class terminals (resource block and time slot symbol set information of legacy terminals), the sixth column to the eighth column are the first class terminals (resource block and time slot symbol set information of 5MHz RedCAP terminals), the third column and the sixth column each represent the RB number of CORESET, and the fourth column and the seventh column each represent the symbol number of CORESET The fifth column and the eighth column each represent a first offset value.

The embodiment of the application can pre-configure the table shown in the table 4 on both the network equipment and the terminal side, or the network equipment configures the table for the terminal. In this way, after receiving the PDCCH configuration information sent by the network device, the first terminal obtains a first value of the first indication information, uses the first value as an index, searches a row corresponding to the first value in the table, and obtains resource block and time slot symbol set information corresponding to a first type of terminal to which the first terminal belongs in the row. For example, when the first value is 8, the resource block and slot symbol set information corresponding to the first terminal is specifically: the RB number is 24, the symbol number is 2, and the first offset value is 4.

TABLE 4 Table 4

In the embodiment of the application, different types of terminals have different resource block and symbol set information of the control resource set, and the resource block and symbol set information of the different control resource sets can be specifically that at least one parameter in the resource block and symbol set information of the control resource sets of the different types of terminals has different values under at least one index. For example, in table 4, the values of the same parameters under the indexes 0 to 5 are the same for the first class terminal and the second class terminal, and the values of the same parameters under the indexes 6 to 14 are not completely the same.

In the embodiment of the present application, the PDCCH configuration information may further include second indication information of a listening occasion. At this time, the first terminal may determine first listening occasion information according to the search space set and the first symbol index set information of the first listening occasion and the second indication information.

Optionally, the search space set and the first symbol index set information of the first monitoring opportunity are the search space set and the first symbol index set information of the monitoring opportunity corresponding to the first type of terminal to which the first terminal belongs. Of course, the embodiment of the application can set the search space set and the first symbol index set information of the unified monitoring time for all terminals, and the application is not particularly limited.

Here, the search space set and the first symbol index set information of the first listening occasion are predefined or network configured. The search space set and the first symbol index set information for the first listening occasion may be information in a configuration table similar to the listening occasion (monitoring occasions) shown in table 2.

The second indication information may specifically be a second field in the PDCCH configuration information, for example, the lower four bits, i.e., the lowest 4 bits, in the pdfch-ConfigSIB 1 information. The first terminal uses the value of the second field as an index, and determines the first monitoring occasion information in the searching space set and the first symbol index set information of the first monitoring occasion.

The first symbol index set information and the search space set of the first listening occasion comprise at least one combination, and each combination comprises at least one parameter of a first parameter O, the number of the search space sets per time slot, a second parameter M and an index of a first symbol of the listening occasion. Wherein the first parameter O represents an offset value of a time slot where a listening occasion of different subcarrier intervals is located, and the second parameter M represents a density of the listening occasions.

In the first case that the bandwidth of CORESET0 of the second class of terminals is not greater than the maximum bandwidth of the first class of terminals, multiplexing the same resource block and symbol set information of the control resource set, the same search space set and first symbol index set information of the monitoring opportunity, and the same monitoring starting time slot calculation formula by the first class of terminals and the second class of terminals;

and under the second condition that the bandwidth of CORESET0 of the second type of terminal is larger than the maximum bandwidth of the first type of terminal and the frequency domain resource positions of the second type of terminal and the CORESET0 of the first type of terminal are overlapped, the first type of terminal and the second type of terminal determine the time slot positions of the monitoring time through different monitoring starting time slot calculation formulas. At this time, the first-class terminal and the second-class terminal may multiplex the same "search space set of listening occasions and first symbol index set information", and implement time division multiplexing of listening occasions by using different listening start time slot calculation formulas.

In the third case that the bandwidth of CORESET0 of the second class terminal is greater than the maximum bandwidth of the first class terminal, and the frequency domain resource positions of CORESET0 of the second class terminal and the first class terminal are not overlapped, the first class terminal and the second class terminal may multiplex the same "search space set and first symbol index set information of listening opportunity" and "listening start time slot calculation formula".

The following description will proceed with an example in which the first type terminal and the second type terminal are a 5MHz RedCap terminal and a legacy terminal, respectively.

The embodiment of the application can realize that when the existing CORESET0 is larger than 5MHz, the monitoring occasion of non-overlapping legacy CORESET0 and 5MHz CORESET0 are indicated simultaneously under the condition of not increasing the number of bits by configuring the low four bits of the PDCCH-ConfigSIB1, multiplexing the CORESET monitor occasion table of the existing type0-PDCCH and resetting the monitoring starting time slot formula. Specific:

(1) When CORESET0 of the legacy terminal is not more than 5MHz,5MHz RedCAP multiplexes the CORESET0 table, CORESET0 monitor occasin table and monitoring starting time slot formula of the existing legacy terminal.

(2) When CORESET0 of legacy terminal is greater than 5MHz andthe 5MHz CORESET0 overlaps with the CORESET0 frequency domain of the legacy terminal, 5MHz CORESET0 monitor occasion is time division multiplexed with the CORESET0 monitor octasion of the legacy terminal, and the monitoring start time slot formula is redesigned. 5MHz CORESET0 is the sequence number M of the listening radio frame corresponding to a certain SSB _frame The method comprises the following steps:

monitoring the starting time slot sequence number as

Wherein i represents an SSB index (SSB index), and the first parameter O represents an offset value of a time slot where a listening occasion of different subcarrier intervals is located; the second parameter M represents the density of listening occasions; μ represents a parameter related to the subcarrier spacing, and reference may be made in particular to the related art;representing the number of slots per subframe; s is S _offset Is the offset of the 5m core 0 listening start time slot relative to the core 0 listening start time slot of the legacy terminal. For example when M of legacy CORESET0 is equal to 1 or 1/2, S _offset Can take N _SSB M, here N _SSB Is the SSB beam number, and for example, when legacy CORESET 0M is equal to 2, S _offset 1 may be taken.

(3) When the CORESET0 of the legacy terminal is greater than 5MHz and the CORESET0 frequency domain of the legacy terminal is not overlapped with the CORESET0 frequency domain of the legacy terminal, the CORESET0 of the legacy terminal can be multiplexed with the CORESET0 monitor timing table and the listening start time slot formula of the legacy terminal by the CORESET0 of the legacy terminal.

In the embodiment of the application, after the first terminal obtains the first resource position information and the first monitoring time information, the first terminal can detect the PDCCH according to the first resource position information and the first monitoring time information. Then, third indication information of the time domain resource allocation domain in the downlink control information is obtained from the detected PDCCH. In this way, the first terminal may determine the first PDSCH time domain resource location information according to the slot offset and symbol set information of the first PDSCH and the third indication information.

Optionally, the time slot offset and symbol set information of the first PDSCH is time slot offset and symbol set information of a PDSCH corresponding to a first type of terminal to which the first terminal belongs. Of course, the embodiment of the present application may also set unified slot offset and symbol set information of PDSCH for all terminals, which is not particularly limited.

Here, the slot offset and symbol set information of the first PDSCH is predefined or network configured. The slot offset and symbol set information of the first PDSCH may be information in a PDSCH TDRA table similar to that shown in table 3.

The slot offset and symbol set information of the first PDSCH comprises at least one combination, each combination comprises a dmrs-type A-Position, PSDCH mapping type (PDSCH mapping type), and a PDSCH initial slot offset K ₀ At least one of parameters such as the number of transmission slots N, the transmission start symbol S, the number of transmission symbols L per slot, etc. And one value of each third indication information corresponds to one or two combinations, wherein the value of the transmission time slot comprises 1 and 2 when the value corresponds to two combinations, and the values respectively indicate that the first PDSCH time domain resource position is on 1 time slot or 2 time slots. Wherein one Transport Block (TB) is transmitted per slot.

Since the number of 5mhz CORESET0 symbols may be greater than 3, some configurations in the existing defaults PDSCH TDRA table are not available and require reconfiguration. By configuring the DCI 1_0Time domain resource assignment domain and the reconfiguration PDSCH TDRA table, flexible scheduling of SIB1 is realized without increasing the bit number.

For example, default PDSCH TDRA table of 5MHz RedCAP terminal contains dmrs-type A-Position, PDSCH mapping type, PDSCH starting slot offset K ₀ The number of transmission slots N, the transmission start symbol S, the number of transmission symbols L per slot. In addition, due to SIB1 time-slot scheduling transmissionsSIB1 has a small number of symbols, and particularly SIB1 is difficult to be carried in one slot when a subcarrier spacing (SCS) is 30kHz, and the number N of PDSCH transmission slots is configured in default PDSCH table, and PDSCH is transmitted in one TB in each slot.

The method of the embodiment of the present application is described above from the terminal side, and the method of the present application is described below from the network device side.

Referring to fig. 3, the resource indication method provided in the embodiment of the present application is applied to a network device, and includes:

Step 301, a network device sends PDCCH configuration information to a first terminal, wherein the PDCCH configuration information includes first indication information for a Type-0PDCCH control resource set CORESET; the first indication information is used for the first terminal to determine first resource position information according to resource block and symbol set information of a first control resource set and the first indication information, so as to obtain a resource position where the control resource set is located, wherein the resource block and symbol set information of the first control resource set is a resource block and symbol set of the control resource set corresponding to a first type of terminal to which the first terminal belongs, and the resource block and symbol set of the corresponding control resource set are set for different types of terminals.

Optionally, in the first case that the bandwidth of CORESET0 of the second class of terminals is not greater than the maximum bandwidth of the first class of terminals, the first class of terminals and the second class of terminals multiplex the same "resource block and symbol set information of control resource set", "search space set and first symbol index set information of listening occasion", and "listening start slot calculation formula".

And under the second condition that the bandwidth of CORESET0 of the second type of terminal is larger than the maximum bandwidth of the first type of terminal and the frequency domain resource positions of the second type of terminal and the CORESET0 of the first type of terminal are overlapped, the first type of terminal and the second type of terminal determine the time slot positions of the monitoring time through different monitoring starting time slot calculation formulas. For example, the first-type terminal and the second-type terminal multiplex the search space set and the first symbol index set information of the same listening opportunity, and implement time division multiplexing of the listening opportunity through different listening start time slot calculation formulas.

Specific examples of several configurations are provided further below taking the first class of terminals and the second class of terminals as 5MHz RedCap terminals and legacy terminals, respectively, as examples.

Example 1:

when both SSB SCS and CORESET0 SCS are 15kHz, CORESET0 configuration table is extended to include resource block and slot symbol set information for the 5MHz RedCap terminal, as shown in table 4 above. Table 4 may be defined as Set of resource blocks and slot symbols of CORESET for Type0-PDCCH search space set when { SS/PBCH block, PDCCH } SCS is {15,15}kHz for frequency bands with minimum channel bandwidth 5MHz or 10MHz.

When index in table 4 is 0-5, 5mhz RedCap terminal multiplexes legacy CORESET0, using the monitor occalasion table of legacy terminal and existing listening start time slot formula. When index in table 4 is 6 to 9, 12 to 14, the 5MHz remote terminal uses the re-designed resource block and slot symbol set information (5 MHz core 0), and since the 5MHz core 0 and legacy core 0 frequency domains overlap, the monitor occalasion table of the legacy terminal and the re-designed listening start slot formula are used. When index in table 4 is 10-11, 5mhz RedCap terminal uses redesigned 5mhz CORESET0, and because 5mhz CORESET0 and existing CORESET0 frequency domains do not overlap, monitor occalasion table and existing listening start time slot formula of legacy terminal are used.

When index in table 4 is 14 and index in table 2 is 0, 1, 8, monitor occasing corresponding to different SSBs for the existing CORESET0 and 5mhz CORESET0 within 20ms is shown in fig. 4, 5, 6. Fig. 4 shows CORESET index=14 (index in table 4), monitor occasion index =0 (index in table 2), S _offset Taking N _SSB Type0-PDCCH monitor occasion at M. Fig. 5 shows CORESET index= 14,monitor occasion index =1, s _offset Taking N _SSB Type0-PDCCH monitor occasion at M. Fig. 6 shows CORESET index= 14,monitor occasion index = 8,S _offset Type0-PDCCH monitor occasion when taken 1. In fig. 6, legacy CORESET0 is time division multiplexed with monitor octasion of 5mhz CORESET0, where the 5mhz CORESET0 frequency domain occupies 24rb, offset=4, 5mhz CORESET0 contains CD-SSB, and no returning is needed to receive CD-SSB and 5mhz CORESET0.

Example 2:

the CORESET0 configuration table was extended to include 5MHz RedCap at 15kHz,CORESET0 SCS of 30kHz as shown in Table 5. Table 5 may be defined as Set of resource blocks and slot symbols of CORESET for Type0-PDCCH search space set when { SS/PBCH block, PDCCH } SCS is {15,30}kHz for frequency bands with minimum channel bandwidth 5MHz or 10MHz.

TABLE 5

Because the number of 5MHz frequency domain symbols is small, SIB1 is difficult to bear in one time slot, 5MHz CORESET0 monitor occasion cannot be too dense, and M is 2. When CORESET index is 6,monitor occasion index, CORESET0 and 5mhz CORESET0 of legacy within 20ms correspond to monitor occalation for different SSBs as shown in fig. 7. Fig. 7 shows types 0-PDCCH monitor occasion at CORESET0 SCS30kHz, CORESET index= 8,monitor occasion index =8. In fig. 7, legacy CORESET0 is frequency division multiplexed with 5mhz CORESET0, where 5MHz CORESET0 offset =30rb is greater than the sum of the number of legacy CORESET0 offset and 5mhz CORESET0 RB, 5mhz CORESET0 is not overlapped with CD-SSB and legacy CORESET0 frequency domains, and returning is needed to receive CD-SSB and 5mhz CORESET0.

The present example reconfigures default PDSCH table of a 5MHz RedCap as shown in table 6. Table 6 may be defined as Default PDSCH time domain resource allocation A for normal CP for MHz RedCAP.

TABLE 5

When DCI 1_0 TDRA field is 0 in the tyoe0-PDCCH corresponding to SSB2, SIB1 transmits two time slots as shown in FIG. 8. Fig. 8 shows a type0-PDCCH scheduling SIB1 corresponding to SSB2 when CORESET0 SCS 30kHz,CORESET index = 8,monitor occasion index =8.

The embodiment of the application realizes that under the condition of not increasing the number of pdcch-ConfigSIB1 bits, the CORESET0 configuration and the non-overlapped CORESET0 monitoring occasion configuration of at least two terminals are respectively indicated by reconfiguring the CORESET0 configuration table. In addition, the embodiment of the application realizes flexible scheduling of the first-class terminal SIB1 under the condition of not increasing the bit number of DCI 1_0 by reconfiguring default PDSCH table of the first-class terminal.
