Description

Technical Field

[0001] This application relates to the field of mobile communication technology, specifically to a resource indication method, a terminal, and a network device. Background Technology

[0002] To meet the needs of certain IoT use cases, such as industrial wireless sensor networks, smart cities, and wearable devices, Reduced Capability (RedCap) terminals reduce terminal complexity and cost by reducing bandwidth, decreasing the number of transceiver antennas, and reducing terminal processing power. RedCap terminals consider reducing the maximum bandwidth to 5MHz, and the reception of the control resource set (CORESET) and System Information Block 1 (SIB1) of the type 0 Physical Downlink Control Channel (type 0-PDCCH) should be limited to within 5MHz.

[0003] In existing technologies, during the cell search phase in New Radio (NR), when the UE determines from the MIB message that a CORESET transmitting Type 0-PDCCH CSS exists, it determines the number of consecutive resource locations (Resource Blocks, RBs) and the number of continuous symbols of the CORESET using the high four bits of the pdcch-ConfigSIB1 information in the Master Information Block (MIB). Table 1 is an example of a configuration table (hereinafter referred to as the CORESET0 configuration table). Different configuration tables will correspond to different subcarrier spacing combinations of {SSB, PDCCH} and different minimum channel bandwidths.

[0004] Under various configurations, the minimum number of redundancies (RBs) in CORESET is 24. This varies depending on the subcarrier spacing and the number of RBs. The bandwidth of CORESET can be determined. Determine the number of symbols in the CORESET. The offset value indicates the number of RBs between the lowest Physical Resource Block (PRB) position of the Synchronization Signal and PBCH block (SSB) and the lowest PRB position of the Type-0 PDCCH CORESET.

[0005]

[0006] Table 1

[0007] The UE determines the time slot position (monitoring occasions) for PDCCH detection using the lowest 4 bits of pdcch-ConfigSIB1. The parameters of the PDCCH detection time slot, determined by the 16 states of the 4 bits, are specified in a table. Depending on the frequency range, the multiplexing pattern of SSB and CORESET, and the subcarrier spacing combination of SSB and PDCCH, the corresponding tables also differ. Table 2 provides an example of the PDCCH monitoring occasion parameters under multiplexing patterns 1 and FR1 of SSB and CORESET.

[0008]

[0009] Table 2

[0010] In Table 2, O represents the offset value of the time slot where the listening opportunity is located for different subcarrier intervals, and M represents the density of listening opportunities.

[0011] For SSB and CORESET multiplexing mode 1, the UE listens to and detects the Type O-PDCCH corresponding to the SSB at a fixed period of 20ms. The listening radio frame corresponding to a certain SSB may be configured in either odd or even frames, depending on... The value of , where i represents the SSB index. When M frame When M is even, the listening timing is placed in even-numbered frames; when M... frame When the number of frames is odd, the listening time slot is placed in an odd-numbered frame. Each listening radio frame contains two consecutive listening time slots. The network is free to place the PDCCH associated with the SSB in either of the two consecutive time slots; therefore, the UE must listen in two consecutive time slots. Listening time slot start position.

[0012] After the UE listens to the TypeO-PDCCH, the frequency domain resources of the TypeO-PDCCH scheduling SIB1 are indicated by the DCI 1_0Frequency domain resource assignment field, and the time domain resources are indicated by the Time domain resource assignment 4 bits, corresponding to the following default PDSCH TDRA table. The existing SIB1 scheduling is all simultaneous slot scheduling.

[0013]

[0014] Table 3

[0015] According to the existing protocol, the CORESET0 and SIB1 of the legacy terminal may be greater than 5MHz. R18RedCap cannot reuse the existing CORESET0 and SIB1 design and needs to design a new CORESET and default PDSCHTDRAtable table for type0-PDCCH. Summary of the Invention

[0051] Please see Figure 1 , Figure 1 This diagram illustrates a block diagram of a wireless communication system applicable to embodiments of this application. The wireless communication system includes a terminal 11 and a network device 12. The terminal 11 can also be referred to as a user terminal or user equipment (UE). The terminal 11 can be a mobile phone, tablet computer, laptop computer, personal digital assistant (PDA), mobile internet device (MID), wearable device, or in-vehicle device, etc. It should be noted that the specific type of terminal 11 is not limited in this embodiment. Network device 12 can be a base station and / or a core network element. The base station can be a 5G or later version base station (e.g., gNB, 5G NR NB, etc.), or a base station in other communication systems (e.g., eNB, WLAN access point, or other access point, etc.). The base station can be referred to as a node B, evolved node B, access point, base transceiver station (BTS), radio base station, radio transceiver, basic service set (BSS), extended service set (ESS), B node, evolved B node (eNB), home B node, home evolved B node, WLAN access point, WiFi node, or any other suitable term in the field. As long as the same technical effect is achieved, the base station is not limited to specific technical terms. It should be noted that in this embodiment of the application, only a base station in an NR system is used as an example, but the specific type of base station is not limited.

[0052] The base station can communicate with terminal 11 under the control of a base station controller, which in various examples may be part of the core network or some base stations. Some base stations may communicate control information or user data with the core network via backhaul. In some examples, some of these base stations may communicate with each other directly or indirectly via backhaul links, which may be wired or wireless communication links. The wireless communication system may support operation on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can transmit modulated signals on multiple carriers simultaneously. For example, each communication link may be a multi-carrier 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, etc.

[0053] The base station can wirelessly communicate with terminal 11 via one or more access point antennas. Each base station can provide communication coverage for its respective coverage area. The coverage area of ​​an access point can be divided into sectors that constitute only a part of that coverage area. The wireless communication system may include different types of base stations (e.g., macro base stations, micro base stations, or pico base stations). Base stations may also utilize different radio technologies, such as cellular or WLAN radio access technologies. Base stations may be associated with the same or different access networks or operator deployments. The coverage areas of different base stations (including coverage areas of the same or different types of base stations, coverage areas using the same or different radio technologies, or coverage areas belonging to the same or different access networks) may overlap.

[0054] Communication links in a wireless communication system may include an uplink for carrying uplink (UL) transmissions (e.g., from terminal 11 to network device 12) or a downlink for carrying downlink (DL) transmissions (e.g., from network device 12 to terminal 11). UL transmissions may also be referred to as reverse link transmissions, and DL transmissions may also be referred to as forward link transmissions. Downlink transmissions may be carried out using licensed frequency bands, unlicensed frequency bands, or both. Similarly, uplink transmissions may be carried out using licensed frequency bands, unlicensed frequency bands, or both.

[0055] This application proposes a resource indication method that enables the configuration of type0-PDCCHCORESET for different types of terminals. Furthermore, this application can also achieve the above configuration while maximizing the reuse of existing PBCH and DCI 1_0 information bits. Even further, this application can also configure the monitoring occasion and default PDSCH time-domain resource for different types of terminals. This application introduces at least two types of terminals. One way to classify different terminals is by the bandwidth range they support. Based on a pre-defined bandwidth range, terminals are divided into different types. These at least two types include a first type of terminal and a second type of terminal. The maximum bandwidth of the first type of terminal is less than the maximum bandwidth of the second type of terminal. For example, the first type of terminal can be a RedCap terminal (also referred to as a RedCap terminal or a 5MHz RedCap terminal in this application, with a bandwidth within 5MHz), while the second type of terminal can be a traditional terminal (also referred to as a legacy terminal in this application, whose bandwidth is typically greater than 5MHz). For ease of description, the type0-PDCCH CORESET will be abbreviated as CORESET0 in this application. In the example description of the above two types, the type0-PDCCH CORESET of the 5MHz RedCap terminal will be abbreviated as 5MHz CORESET0, and the type0-PDCCH CORESET of the traditional terminal will be abbreviated as legacy CORESET0.

[0056] Please refer to Figure 2 The resource indication method provided in this application, when applied to the terminal side, includes:

[0057] Step 201: Receive PDCCH configuration information sent by the network, wherein the PDCCH configuration information includes first indication information for the Type-0 PDCCH control resource set CORESET.

[0058] Here, PDCCH configuration information can be carried in MIB messages, for example, the pdcch-ConfigSIB1 information carried in the MIB. The pdcch-ConfigSIB1 information usually has 8 bits. Specifically, the first indication information can be the high four bits of the pdcch-ConfigSIB1 information, that is, the highest 4 bits.

[0059] Step 202: Determine the first resource location information based on the resource block and symbol set information of the first control resource set and the first indication information, and obtain the resource location where the control resource set is located. 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 type of 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 types of terminals.

[0060] In this embodiment, resource block and symbol set information for control resource sets is set for different terminal types. This information indicates the resource location of the terminal's control resource set. The resource block and symbol set information for each terminal can be predefined or network-configured. Specifically, the resource block and symbol set information for control resource sets can be similar to the information in the CORESET0 configuration table shown in Table 1.

[0061] Through the above steps, the embodiments of this application can realize the type0-PDCCH CORESET configuration of different types of terminals.

[0062] In this embodiment, the first indication information may be the first field in the PDCCH configuration information, for example, the high four bits of the pdcch-ConfigSIB1 information. In step 202, the first terminal can use the value of the first field as an index to determine the first resource location information in the resource block and symbol set information of the first control resource set.

[0063] 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 among the number of RBs, the number of symbols, and a first offset value, wherein the first offset value represents the offset between the minimum RB index of the control resource set of Type-0 PDCCH and the common RB index overlapping with the minimum RB of SSB, or the offset between the minimum RB index of the control resource set of Type-0 PDCCH and the minimum RB index of the control resource set of Type-0 PDCCH of the second type of terminal, or the offset between the minimum RB index of the control resource set of Type-0 PDCCH and the maximum RB index of the control resource set of Type-0 PDCCH of the second type of terminal.

[0064] Thus, by configuring the high four bits of pdcch-ConfigSIB1 and reconfiguring the CORESET configuration table of type0-PDCCH, this embodiment of the application achieves the simultaneous indication of the CORESET0 configuration of different types of terminals (e.g., indicating legacy CORESET0 and 5MHz CORESET0 configuration) without increasing the number of bits. The following description uses the first type of terminal and the second terminal as examples, namely a 5MHz RedCap terminal and a legacy terminal, respectively.

[0065] The CORESET0 configuration table for the first type of terminal (such as a 5MHz RedCap terminal) includes the SSB and CORESET multiplexing methods, the number of RBs in the CORESET, the number of symbols, and the frequency domain offset (first offset value). Since the number of RBs in 5MHz is relatively small, in order to support a higher aggregation level, this embodiment of the application expands the number of symbols in 5MHz CORESET0 from a maximum of 3 in Table 1 to a maximum of N, where N is greater than 3.

[0066] The first offset value (frequency domain offset) means the offset between the smallest RB index of 5MHz CORESET0 and the common RB index that overlaps with the smallest RB of SSB, or the offset between the smallest RB index of 5MHz CORESET0 and the smallest RB index of legacyCORESET0, or the offset between the smallest RB index of 5MHz CORESET0 and the largest RB index of legacyCORESET0. Specifically, the first offset value (frequency domain offset) may have the following values:

[0067] (1) The first type is when the 5MHz CORESET0 and CD-SSB frequency domains overlap. In this case, the first offset value of 5MHz CORESET0 is greater than or equal to 0 and less than or equal to the difference between the number of RBs of 5MHz CORESET0 and the number of RBs of the cell-defined SSB (CD-SSB).

[0068] (2) The second scenario is that the 5MHz CORESET0 frequency domain does not overlap with the legacy CORESET0 and CD-SSB frequency domains. When the first offset value is positive and less than the starting RB number of CD-SSB, the 5MHz CORESET0 frequency domain is offset downwards relative to the legacy CORESET0 frequency domain, and the offset of the 5MHz CORESET0 is greater than or equal to the sum of the first offset value of the legacy CORESET0 and the number of RBs in the 5MHz CORESET0 frequency domain, or greater than or equal to the number of RBs in the 5MHz CORESET0 frequency domain. When the first offset value is negative and its absolute value is greater than or equal to the number of RBs in the legacy CORESET0 minus the first offset value of the legacy CORESET0 frequency domain, or its absolute value is greater than or equal to 0, the 5MHz CORESET0 frequency domain is offset upwards relative to the legacy CORESET0 frequency domain.

[0069] Table 4 provides an example of a CORESET0 configuration table in an embodiment of this application. The first column contains the CORESET0 index; the second column represents the SSB and CORESET0 multiplexing pattern; columns three to five contain resource block and time slot symbol set information for the second type of terminal (legacy terminal); and columns six to eight contain resource block and time slot symbol set information for the first type of terminal (5MHz RedCap terminal). Columns three and six both represent the number of RBs in the CORESET, and columns four and seven both represent the number of symbols in the CORESET. Both the fifth column and the eighth category represent the first offset value.

[0070] In this embodiment, the table shown in Table 4 can be pre-configured on both the network device and the terminal side, or the network device can configure the table for the terminal. Thus, after receiving the PDCCH configuration information sent by the network device, the first terminal obtains the first value of the first indication information therein, uses the first value as an index to find the row corresponding to the first value in the table, and obtains the resource block and time slot symbol set information corresponding to the first type of terminal to which the first terminal belongs from that row. For example, when the first value is 8, the resource block and time slot symbol set information corresponding to the first terminal is specifically: RB number is 24, symbol number is 2, and first offset value is 4.

[0071]

[0072] Table 4

[0073] In this embodiment, different types of terminals have different resource block and symbol set information for their control resource sets. Specifically, the resource block and symbol set information for different control resource sets can mean that, at least under one index, the values ​​of at least one parameter in the resource block and symbol set information of the control resource sets for different types of terminals are different. For example, in Table 4, the values ​​of the same parameter are the same for the first type of terminal and the second type of terminal under indices 0 to 5, but the values ​​of the same parameter are not completely the same under indices 6 to 14.

[0074] In this embodiment, the PDCCH configuration information may further include second indication information for the listening timing. In this case, the first terminal can determine the first listening timing information based on the search space set and the first symbol index set information of the first listening timing, and the second indication information.

[0075] Optionally, the search space set and the first symbol index set information of the first monitoring timing are the search space set and the first symbol index set information of the monitoring timing corresponding to the first type of terminal to which the first terminal belongs. Of course, in this embodiment of the application, a unified search space set and first symbol index set information of the monitoring timing can also be set for all terminals, and this application does not specifically limit this.

[0076] Here, the search space set and the first symbol index set information for the first monitoring occasion are either predefined or network-configured. The search space set and the first symbol index set information for the first monitoring occasion can be similar to the information in the monitoring occasions configuration table shown in Table 2.

[0077] The second indication information may specifically be the second field in the PDCCH configuration information, for example, the lower four bits (the lowest four bits) of the pdcch-ConfigSIB1 information. The first terminal uses the value of the second field as an index to determine the first listening timing information from the search space set and the first symbol index set information of the first listening timing.

[0078] The search space set and first symbol index set information for the first listening opportunity include at least one combination, each combination including at least one of the following parameters: a first parameter O, the number of search space sets per time slot, a second parameter M, and the index of the first symbol of the listening opportunity. The first parameter O represents the offset value of the time slot where the listening opportunities for different subcarrier intervals are located, and the second parameter M represents the density of the listening opportunities.

[0079] In the first case where the bandwidth of CORESET0 of the second type of terminal is not greater than the maximum bandwidth of the first type of terminal, the first type of terminal and the second type of terminal reuse the same "resource block and symbol set information of control resource set", "search space set and first symbol index set information of listening timing", and "calculation formula for listening start time slot".

[0080] In the second scenario, where the bandwidth of CORESET0 of the second type of terminal is greater than the maximum bandwidth of the first type of terminal, and the frequency domain resource locations of CORESET0 of the second type of terminal and the first type of terminal overlap, the first type of terminal and the second type of terminal determine the time slot location of the listening opportunity using different listening start time slot calculation formulas. In this case, the first type of terminal and the second type of terminal can reuse the same "search space set and first symbol index set information for listening opportunities," and achieve time-division multiplexing of listening opportunities through different listening start time slot calculation formulas.

[0081] In the third case, where the bandwidth of CORESET0 of the second type of terminal is greater than the maximum bandwidth of the first type of terminal, and the frequency domain resource positions of CORESET0 of the second type of terminal and the first type of terminal do not overlap, the first type of terminal and the second type of terminal can reuse the same "search space set and first symbol index set information of listening timing" and "calculation formula of listening start time slot".

[0082] The following explanation will continue using the first type of terminal and the second type of terminal as examples, namely a 5MHz RedCap terminal and a legacy terminal, respectively.

[0083] This application embodiment, by configuring the lower four bits of pdcch-ConfigSIB1, reusing the existing type0-PDCCH CORESET monitor occasion table, and redesigning the monitoring start time slot formula, achieves the simultaneous indication of non-overlapping legacy CORESET0 and 5MHz CORESET0 monitoring occasions without increasing the number of bits when the existing CORESET0 is greater than 5MHz. Specifically:

[0084] (1) When the CORESET0 of the legacy terminal is not greater than 5MHz, the 5MHz RedCap reuses the existing legacy terminal's CORESET0 table, CORESET0 monitor occasion table and monitoring start time slot formula.

[0085] (2) When the CORESET0 of the legacy terminal is greater than 5MHz and the frequency domains of 5MHz CORESET0 overlap with those of the legacy terminal's CORESET0, the 5MHz CORESET0 monitor occasion and the legacy terminal's CORESET0 monitor occasion are time-division multiplexed, and the monitoring start time slot formula is redesigned. 5MHz CORESET0 corresponds to the sequence number M of a monitoring radio frame of a certain SSB. frame for:

[0086]

[0087] The monitoring start time slot number is

[0088] Where i represents the SSB index, the first parameter O represents the offset value of the time slot where the listening opportunity is located for different subcarrier intervals, the second parameter M represents the density of listening opportunities, and μ represents the parameters related to the subcarrier interval, which can be referred to in relevant existing technologies for details; S represents the number of time slots in each subframe; offset This is the offset of the 5M CORESET0 listener start time slot relative to the legacy terminal's CORESET0 listener start time slot. For example, when M of legacy CORESET0 equals 1 or 1 / 2, S... offset N can be chosen SSB M, here, N SSB It refers to the number of SSB beams. For example, when legacy CORESET0 M equals 2, S offset One can be chosen.

[0089] (3) When the CORESET0 of the legacy terminal is greater than 5MHz and the frequency domains of 5MHz CORESET0 and the CORESET0 of the legacy terminal do not overlap, 5MHz CORESET0 can reuse the CORESET0 monitor occasion table and the monitoring start time slot formula of the legacy terminal.

[0090] In this embodiment, after obtaining the first resource location information and the first listening opportunity information, the first terminal can detect the PDCCH based on the first resource location information and the first listening opportunity information. Then, it obtains the third indication information of the time-domain resource allocation field in the downlink control information from the detected PDCCH. In this way, the first terminal can determine the time-domain resource location information of the first PDSCH based on the time slot offset and symbol set information of the first PDSCH and the third indication information.

[0091] Optionally, the slot offset and symbol set information of the first PDSCH is the slot offset and symbol set information of the PDSCH corresponding to the first type of terminal to which the first terminal belongs. Of course, embodiments of this application may also set uniform slot offset and symbol set information for all terminals, and this application does not specifically limit this.

[0092] Here, the slot offset and symbol set information of the first PDSCH are predefined or network-configured. The slot offset and symbol set information of the first PDSCH can be similar to the information in the PDSCH TDRA table shown in Table 3.

[0093] The first PDSCH's slot offset and symbol set information includes at least one combination. Each combination includes at least one of the following parameters: dmrs-TypeA-Position, PDSCH mapping type, PDSCH start slot offset K0, number of transmission slots N, start symbol S, and number of symbols transmitted per slot L. Each value of the third indication information corresponds to one or two combinations. When corresponding to two combinations, the transmission slot value includes 1 and 2, indicating that the first PDSCH time-domain resource location is on one or two slots, respectively. Each slot transmits one transport block (TB).

[0094] The following explanation will continue using the first type of terminal and the second type of terminal as examples, namely a 5MHz RedCap terminal and a legacy terminal, respectively.

[0095] Since the number of 5MHz CORESET0 symbols may be greater than 3, some configurations in the existing default PDSCH TDRA table are unavailable and need to be reconfigured. By configuring the DCI 1_0Time domain resource assignment field and reconfiguring the PDSCH TDRA table, flexible scheduling of SIB1 is achieved without increasing the number of bits.

[0096] For example, the default PDSCH TDRA table for a 5MHz RedCap terminal includes dmrs-TypeA-Position, PDSCH mapping type, PDSCH start time slot offset K0, number of transmission time slots N, transmission start symbol S, and number of symbols transmitted per time slot L. Additionally, because the number of SIB1 symbols transmitted when scheduling SIB1 in the same time slot is relatively small, especially when the sub-carrier space (SCS) is 30kHz, it is difficult for SIB1 to be carried within a single time slot. Therefore, the default PDSCH table is configured with the number of PDSCH transmission time slots N, and one TB of PDSCH is transmitted in each time slot.

[0097] The methods of the embodiments of this application have been described above from the perspective of the terminal side. The methods of this application are described below from the perspective of the network device side.

[0098] Please follow Figure 3 The resource indication method provided in this application embodiment, when applied to a network device, includes:

[0099] Step 301: The network device sends PDCCH configuration information to the first terminal. The PDCCH configuration information includes first indication information for the Type-0 PDCCH control resource set CORESET. The first indication information is used to enable the first terminal to determine the first resource location information based on the resource block and symbol set information of the first control resource set and the first indication information, thereby obtaining the resource location of the control resource set. The resource block and symbol set information of the first control resource set is the resource block and symbol set of the control resource set corresponding to the first type of terminal to which the first terminal belongs, and the resource block and symbol set of the corresponding control resource set is set for different types of terminals.

[0100] Through the above steps, this application embodiment realizes the type0-PDCCH CORESET configuration for different types of terminals.

[0101] Specifically, in this embodiment, the types of terminals include a first type of terminal and a second type of terminal, wherein the maximum bandwidth of the first type of terminal is less than the maximum bandwidth of the second type of terminal. The resource block and symbol set information of the first control resource set can be predefined or network-configured.

[0102] The resource block and time slot symbol set information of the first control resource set specifically includes a combination of at least one number of RBs, a number of symbols, and a first offset value. The first offset value represents the offset between the minimum RB index of the control resource set of the Type-0 PDCCH and the common RB index that overlaps with the minimum RB of the SSB, or the offset between the minimum RB index of the control resource set of the Type-0 PDCCH of the Type-0 terminal and the minimum RB index of the control resource set of the Type-0 PDCCH of the second type terminal, or the offset between the minimum RB index of the control resource set of the Type-0 PDCCH of the Type-0 terminal and the maximum RB index of the control resource set of the Type-0 PDCCH of the second type terminal.

[0103] Optionally, the PDCCH configuration information further includes second indication information for the listening timing; the second indication information is used for the first terminal to determine the first listening timing information based on the search space set and the first symbol index set information of the first listening timing and the second indication information.

[0104] Optionally, the search space set and the first symbol index set information of the first listening time are the search space set and the first symbol index set information of the listening time corresponding to the first type of terminal to which the first terminal belongs.

[0105] Here, the search space set and the first symbol index set information for the first listening opportunity can be predefined or network-configured.

[0106] The search space set and first symbol index set information for the first listening time slot include a combination of at least one first parameter O, the number of search space sets per time slot, a second parameter M, and the index of the first symbol of the listening time slot.

[0107] Optionally, in the first case where the bandwidth of CORESET0 of the second type of terminal is not greater than the maximum bandwidth of the first type of terminal, the first type of terminal and the second type of terminal reuse the same "resource block and symbol set information of the control resource set", "search space set and first symbol index set information of the listening timing", and "calculation formula for the listening start time slot".

[0108] In the second scenario, where the bandwidth of CORESET0 of the second type of terminal is greater than the maximum bandwidth of the first type of terminal, and the frequency domain resource locations of CORESET0 of the second type of terminal and the first type of terminal overlap, the first type of terminal and the second type of terminal determine the time slot location of the listening opportunity using different listening start time slot calculation formulas. For example, the first type of terminal and the second type of terminal can reuse the same "search space set and first symbol index set information of the listening opportunity", and achieve time-division multiplexing of the listening opportunity by using different listening start time slot calculation formulas.

[0109] In the third case, where the bandwidth of CORESET0 of the second type of terminal is greater than the maximum bandwidth of the first type of terminal, and the frequency domain resource positions of CORESET0 of the second type of terminal and the first type of terminal do not overlap, the first type of terminal and the second type of terminal reuse the same "search space set and first symbol index set information of listening timing" and "calculation formula of listening start time slot".

[0110] In this embodiment of the application, the network device may also send a PDCCH carrying downlink control information according to the first resource location information and the first listening timing information. The downlink control information includes third indication information of time domain resource allocation domain. The third indication information is used for the first terminal to determine the time domain resource location information of the first PDSCH according to the time slot offset and symbol set information of the first PDSCH and the third indication information.

[0111] Optionally, the slot offset and symbol set information of the first PDSCH is the slot offset and symbol set information of the PDSCH corresponding to the first type of terminal to which the first terminal belongs.

[0112] Here, the slot offset and symbol set information of the first PDSCH can be predefined or network-configured.

[0113] The first PDSCH slot offset and symbol set information includes at least one combination of dmrs-TypeA-Position, PDSCH mapping type, PDSCH start slot offset K0, number of transmission slots N, transmission start symbol S, and number of symbols transmitted per slot L, and one value for each third indication information, corresponding to one or two combinations. When corresponding to two combinations, the value of the transmission slot includes 1 and 2, respectively indicating that the first PDSCH time domain resource position is on 1 slot or 2 slots, and each slot transmits one TB.

[0114] The following provides specific examples of several configurations, using the first type of terminal and the second type of terminal as examples, which are respectively 5MHz RedCap terminals and legacy terminals.

[0115] Example 1:

[0116] When both SSB SCS and CORESET0 SCS are 15kHz, the CORESET0 configuration table is expanded to include the resource block and slot symbol set information for the 5MHz RedCap terminal, as shown in Table 4 above. Table 4 can 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 of 5MHz or 10MHz.

[0117] When the index in Table 4 is 0–5, the 5MHz RedCap terminal reuses the legacy CORESET0, using the legacy terminal's monitor occasion table and the existing monitoring start time slot formula. When the index in Table 4 is 6–9, or 12–14, the 5MHz RedCap terminal uses the redesigned resource block and time slot symbol set information (5MHz CORESET0). Since the frequency domains of 5MHz CORESET0 and legacy CORESET0 overlap, the legacy terminal's monitor occasion table and the redesigned monitoring start time slot formula are used. When the index in Table 4 is 10–11, the 5MHz RedCap terminal uses the redesigned 5MHz CORESET0. Since the frequency domains of 5MHz CORESET0 and the existing CORESET0 do not overlap, the legacy terminal's monitor occasion table and the existing monitoring start time slot formula are used.

[0118] When the index in Table 4 is 14 and the indexes in Table 2 are 0, 1, and 8, within 20ms, the existing CORESET0 and 5MHz CORESET0 monitor occasions corresponding to different SSBs are as follows: Figure 4 , 5 As shown in Figures 6 and 6. Among them, Figure 4 This indicates that CORESETindex = 14 (the index in Table 4), monitor occasion index = 0 (the index in Table 2), and S offset Take N SSB M-time type0-PDCCH monitor occasion. Figure 5This indicates that CORESET index = 14, monitor occasionindex = 1, and S offset Take N SSB M-time type0-PDCCH monitor occasion. Figure 6 This indicates that CORESET index = 14, monitor occasion index = 8, and S offset The type0-PDCCH monitor occasion when 1 is selected. Figure 6 In the monitor occasion time-division multiplexing of legacy CORESET0 and 5MHz CORESET0, the frequency domain of 5MHz CORESET0 occupies 24RB, offset=4, and 5MHz CORESET0 includes CD-SSB. Reception of CD-SSB and 5MHz CORESET0 does not require retuning.

[0119] Example 2:

[0120] When the SSB SCS is 15kHz and the CORESET0 SCS is 30kHz, the CORESET0 configuration table is expanded to include 5MHz RedCap as shown in Table 5. Table 5 can 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 of 5MHz or 10MHz.

[0121]

[0122] Table 5

[0123] Because the number of symbols in the 5MHz frequency domain is relatively small, SIB1 cannot be carried out within a single time slot. Therefore, the 5MHz CORESET0 monitor occasions cannot be too frequent, and M is set to 2. When the CORESET index is 6 and the monitor occasion index is 8, the legacy CORESET0 and 5MHz CORESET0 within 20ms correspond to different SSBs and their corresponding monitor occasions as follows: Figure 7 As shown. Figure 7This indicates the type0-PDCCH monitor occasion when CORESET0 SCS30kHz, CORESET index=8, and monitor occasion index=8. Figure 7 In the case of frequency division multiplexing of legacy CORESET0 and 5MHz CORESET0, the offset of 5MHz CORESET0 = 30RB is greater than the sum of the offset of legacy CORESET0 and the number of RBs of 5MHz CORESET0. The frequency domains of 5MHz CORESET0, CD-SSB and legacy CORESET0 do not overlap. Retuning is required to receive CD-SSB and 5MHz CORESET0.

[0124] This example reconfigures the default PDSCH table for 5MHz RedCap as shown in Table 6. Table 6 can be defined as Default PDSCH time domain resource allocation A for normal CP for 5MHz RedCap.

[0125]

[0126] Table 5

[0127] When the DCI 1_0 TDRA field in the tyoe0-PDCCH corresponding to SSB2 is 0, such as Figure 8 The SIB1 transmission shows two time slots. Figure 8 SSB2 corresponds to type 0-PDCCH scheduling SIB1 when CORESET0 SCS 30kHz, CORESET index=8, and monitor occasion index=8.

[0128] This application embodiment, by reconfiguring the CORESET0 configuration table, enables the indication of CORESET0 configurations for at least two types of terminals and non-overlapping CORESET0 monitoringoccasion configurations without increasing the number of pdcch-ConfigSIB1 bits. Furthermore, this application embodiment also achieves flexible scheduling of the first type of terminal SIB1 without increasing the number of DCI 1_0 bits by reconfiguring the default PDSCH table.
