[0017] 1 is a structural diagram of a wireless communication system according to an embodiment of the present application. The wireless communication system includes a terminal 11 and a network side device 12. Here, the terminal 11 may be referred to as a terminal device or user equipment (UE), and may be a terminal side device such as a mobile phone, a tablet personal computer (PDA), a laptop computer (also called a notebook computer), a personal digital assistant (PDA), a palmtop computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile internet device (MID), a wearable device (WD), a vehicle-mounted equipment (VUE), a pedestrian-mounted equipment (PUE), etc., where the wearable device includes a bracelet, an earphone, glasses, etc. It should be noted that the embodiment of the present application does not limit the specific type of the terminal 11. The network side equipment 12 may be a base station or a core network, where the base station may be called a Node B, an evolved Node B, an access point, a base transceiver station (BTS), a radio base station, a radio transceiver, a basic service set (BSS), an extended service set (ESS), a B node, an evolved B node (eNB), a home B node, a home evolved B node, a WLAN access point, a WiFi node, a transmitting receiving point (TRP), or any other suitable term in the art, as long as the same technical effect is achieved. The base station is not limited to a specific technical term. For illustrative purposes, the embodiments of this application only take base stations in an NR system as examples, but do not limit the specific type of base station.

[0018] To better understand each embodiment of the present application, the following will first be introduced.

[0019] (1) Frame structure, To support various frequency bands and deployment scenarios, New Radio (NR) supports flexible numerology arrangements. One numerology (represented by μ) corresponds to one subcarrier spacing arrangement (and cyclic prefix length) in the frequency domain. NR defines several different numerologies by multiplying the basic subcarrier spacing (15 kHz) by an integer N (i.e., expanding it by N times, where N = 2n, where n is an integer). These are shown in Table 1 below.

[0020] [Table 1]

[0021] As shown in Table 1, as the SCS increases, the number of slots included in each subframe increases exponentially, but the occupancy time of each slot decreases exponentially.

[0022] (2) Periodic signal NR has several types of signals, some of which are periodically arranged, i.e., the arrangement parameters specify the period, offset value, number of duration slots, and number of symbols per slot of this signal. This arrangement tells the base station or UE where to find the required signal.

[0023] This type of periodic signal includes search space configuration in the Physical Downlink Control Channel (PDCCH), Channel State Information Reference Signal (CSI-RS) resource configuration (NZP CSI-RS, ZP-CSIRS), Tracking Reference Signal (TRS) resource configuration, Receiver Signal Strength Indicator (RSSI), Synchronization Signal and PBCH Block-Measurement Timing Configuration (SSB-MTC), dedicated scheduling request (based on the scheduling request resource configuration, physical layer resources on the PUCCH are determined, and the UE can use the physical layer resources to transmit the dedicated scheduling request, i.e., SchedulingRequestResourceConfig determines physical layer resources on the PUCCH where the UE may send the dedicated scheduling request), Sounding Reference Signal (SRS) resource configuration, etc., where PUCCH refers to the Physical Uplink Control Channel.

[0024] Taking the search space arrangement in the physical downlink control channel (PDCCH) as an example, (3) PDCCH The PDCCH is a downlink control channel that carries control information (Downlink Control Information, DCI) for the uplink physical shared channel (PUSCH) and the physical downlink shared channel (PDSCH). In Long Term Evolution (LTE), the PDCCH occupies the entire bandwidth in the frequency domain and the first 1 to 3 symbols of each subframe in the time domain. In NR, if the PDCCH continues to occupy the entire bandwidth as in LTE, it will undoubtedly lead to resource waste and increase the requirements for user equipment (UE) (a terminal will be taken as an example in each embodiment of this application), which is disadvantageous to reducing terminal costs. Therefore, the PDCCH in NR is located within a bandwidth part (BWP) and does not occupy a fixed number of slots in the time domain. In NR, the PDCCH time-frequency resources are mainly determined by the control-resource set (CORESET) and the search space.

[0025] (4) Control resource set (CORESET), CORESET solves the problem of PDCCH range, such as its time domain length and frequency domain range. Because the NR system bandwidth is very large (up to 400 M), following the LTE static configuration method (which occupies the entire system bandwidth) would significantly increase the blind detection complexity. Therefore, NR may adopt a configurable CORESET, and the time domain length and frequency domain range of CORESET may be configured by system information or a dedicated Radio Resource Control (RRC) message.

[0026] The specific meanings of the configuration parameters related to the RRC configuration are as shown in Table 2 below.

[0027] [Table 2]

[0028] As can be seen from the RRC signaling, the placement of the CORESET does not specify a specific time domain location (only the time domain duration (number of symbols) is given), but the specific time domain location is given by the Search Space. This design can obtain greater flexibility. The CORESET may be placed at any frequency domain location (the placement parameter FrequencyDomainResources IE is a bitmap of the physical resource block (PRB) numbers of the current BWP).

[0029] (5) Search space, The search space solves the problem of how the UE searches. A similar concept exists in LTE, and its purpose is to reduce the blind detection complexity of the UE as much as possible. Unlike LTE, the search space in NR targets a single CORESET. NR can configure different search spaces for different UEs, that is, configure different blind detection methods (e.g., monitoring period, monitoring symbol start position, etc.) for different UEs. This further reduces the blind detection complexity of the UE.

[0030] The specific meanings of the configuration parameters related to the RRC configuration are as shown in Table 3 below.

[0031] [Table 3]

[0032] Assume that the CORESET is arranged as follows:

[0033] frequencyDomainResources=0001111111111--(three 0s, twelve 1s), which indicates that CORESET is offset by three PRBs from the position of PRB0, and that 12 PRBs are consecutive.

[0034] Duration=2, which indicates that this CORESET occupies two consecutive OFDM symbols.

[0035] The layout of the search space is assumed to be as follows:

[0036] monitoringSlotPeriodicityAndOffset=sl4.2, which indicates that the period of the search space is 4 slots and is offset by 2 slots.

[0037] Monitoring Symbols Within Slot = 00100000100000, which indicates that in each Slot, two Occasions start from the third and ninth symbols, respectively.

[0038] Duration=2 indicates that the search space has two consecutive slots, and each slot exists.

[0039] FIG. 2 is a schematic diagram of a signal constellation according to an embodiment of the present application, and shows a signal constellation diagram based on the above CORESET and Search space.

[0040] The following describes in detail the signal placement method and apparatus according to the embodiments of the present application through several embodiments and its application scenarios in conjunction with the drawings.

[0041] FIG. 3 is a flowchart of a signal placement method according to an embodiment of the present application. As shown in FIG. 3, the method includes the following steps:

[0042] In step 300, the communication device configures a first periodic signal based on first configuration information; wherein the second configuration information in the first configuration information is determined based on a subcarrier spacing SCS, and / or the second configuration information in the first configuration information is predefined; The first arrangement information is Periodic arrangement information; slot offset information; Duration information; Symbol position arrangement information.

[0043] Alternatively, the communication device may be a terminal.

[0044] Alternatively, the communication device may be a network side device.

[0045] Optionally, the placement information of the periodic signal may be redefined or updated to overcome the fact that using a larger SCS reduces the maximum period it supports.

[0046] Optionally, the placement information of the periodic signal may be redefined or updated based on the value of the SCS.

[0047] Optionally, the first arrangement information is information necessary for the arrangement of the first periodic signal.

[0048] Alternatively, the second configuration information may be a part or all of the configuration information that has been redefined or updated based on the value of the SCS, or may be a part or all of the configuration information that has been directly predefined.

[0049] Alternatively, the B52.6 GHz system may introduce a larger subcarrier spacing (SCS), e.g., SCS=480K / 960K. This increases the number of slots included in one subframe, but the occupancy time of each slot may be very short. In this case, depending on the UE's capabilities, i.e., considering the UE's blind detection complexity and data processing capabilities, some short-period configurations in the search space, such as a 1-, 2-, or 4-slot configuration, may not be applicable to many periodic signals. If a long-period configuration is used, e.g., an 80-slot period, the offset configuration requires 7 bits (27=128>80), resulting in a significant overhead. Conventional configurations support a maximum period of 2560 slots, which requires 320 ms for SCS=120K. Using a larger SCS, e.g., SCS=960K, still requires 40 ms for a 2560-slot period. Therefore, using a larger SCS causes a reduction in the maximum period it supports.

[0050] Therefore, to overcome the above drawbacks, some or all of the configuration information may be redefined or updated based on the value of the SCS, or some or all of the configuration information may be directly predefined.

[0051] Optionally, the communication device may configure the first periodic signal based on the periodic configuration information, slot offset information, duration information, and symbol position configuration information, where all or a part of the configuration information (i.e., the second configuration information) is determined based on the subcarrier spacing SCS, and / or all or a part of the configuration information (i.e., the second configuration information) is predefined.

[0052] Alternatively, the first periodic signal may be any one of the periodically arranged signals, i.e., the arrangement parameters may include the period of this signal, the offset value, the number of duration slots, and the number of symbols occupying a single slot.

[0053] In the embodiments of the present application, by determining the allocation information of the periodic signal based on the subcarrier spacing SCS and / or predefining the allocation information of the first periodic signal, more appropriate resource allocation for the periodic signal can be performed, thereby realizing adaptation to the allocation of periodic signals in the case of multiple types of subcarrier spacing, thereby reducing the blind detection complexity of the terminal and lowering the requirements for the data processing capability of the terminal.

[0054] Optionally, the second configuration information is: Periodic arrangement information; slot offset information; Duration information; and symbol position arrangement information.

[0055] Optionally, all or part of the information for arranging the periodic signal may be predefined or updated, so that the second arrangement information is: Periodic arrangement information; slot offset information; Duration information; The symbol position arrangement information may include any one of the above or a combination thereof.

[0056] Alternatively, only one or more types of configuration information may be updated or predefined, or only another type or types of configuration information may be updated or predefined, or multiple types of information may be updated or predefined simultaneously.

[0057] For example, only the periodic allocation information may be updated or predefined, only the slot offset information may be updated or predefined, or both the periodic allocation information and the slot offset information may be updated or predefined at the same time, but this embodiment is not limited thereto, and other combinations of second allocation information may be similar.

[0058] Alternatively, one or more of the configuration information may be updated or predefined according to the same method, or one or more of the configuration information may be updated or predefined according to different methods, or one or more of the configuration information may be predefined, and one or more of the same or different configuration information may be updated when configuring signals, and this embodiment is not limited thereto.

[0059] For example, the periodic arrangement information and the slot offset information may be updated or predefined according to the same method, or may be updated or predefined according to different methods, or the periodic arrangement information may be predefined and the slot offset information may be updated when the signal is arranged, or the slot offset information may be predefined and the periodic arrangement information may be updated when the signal is arranged, but this embodiment is not limited to this, and other combinations of second arrangement information are similar.

[0060] In the embodiment of the present application, multiple possibilities of second arrangement information to be used for arranging the periodic signal after being updated or predefined are provided, thereby realizing more flexible arrangement of the periodic signal.

[0061] Optionally, when the second configuration information includes periodic configuration information and / or slot offset information, determining the second configuration information based on a subcarrier spacing SCS includes: updating the second configuration information based on a subcarrier spacing SCS; or The second configuration information is predefined based on a subcarrier spacing SCS.

[0062] Alternatively, the periodic arrangement information and / or slot offset information may be updated or redefined, i.e., when the second arrangement information includes periodic arrangement information and / or slot offset information, the communication device may update the second arrangement information based on the subcarrier spacing SCS, or the communication device may pre-define the second arrangement information based on the subcarrier spacing SCS.

[0063] Optionally, when configuring the first periodic signal, the communication device may update the second configuration information based on the subcarrier spacing SCS, i.e., update the periodic configuration information and / or slot offset information.

[0064] Alternatively, before configuring the first periodic signal, second configuration information related to the subcarrier spacing SCS may be preset by the system or predefined by a protocol, and the communication device may directly use the predefined second configuration information when configuring the first periodic signal, i.e., update the periodic configuration information and / or slot offset information.

[0065] Alternatively, when the second configuration information includes periodic configuration information, the communication device may update the periodic configuration information based on the subcarrier spacing SCS, or may predefine the periodic configuration information based on the subcarrier spacing SCS, and the communication device uses the predefined periodic configuration information when configuring the first periodic signal.

[0066] Alternatively, when the second configuration information includes slot offset information, the communication device may update the slot offset information based on the subcarrier spacing SCS, or may predefine the slot offset information based on the subcarrier spacing SCS, and the communication device uses the predefined slot offset information when configuring the first periodic signal.

[0067] For example, take updating monitoringSlotPeriodicityAndOffset in the Search space with a subcarrier spacing SCS as an example. For example, when a communication device configures a first periodic signal, the communication device may directly multiply the period value in monitoringSlotPeriodicityAndOffset in the Search space by a fixed value based on the original configuration value to obtain an updated value, and then determine the period of the first periodic signal based on the updated period value.

[0068] For example, take updating monitoringSlotPeriodicityAndOffset in the Search space with the subcarrier spacing SCS as an example. For example, a new period value for monitoringSlotPeriodicityAndOffset in the Search space may be predefined, and this predefined period value may be determined by directly multiplying a fixed value based on the original value, and the communication device may determine the period of the first periodic signal based on the predefined new period value.

[0069] For example, take updating monitoringSlotPeriodicityAndOffset in the Search space with a subcarrier spacing SCS as an example. For example, when a communication device configures a first periodic signal, the communication device may directly multiply the slot offset information offset in monitoringSlotPeriodicityAndOffset in the Search space by a fixed value based on the original configuration value to obtain an updated value, and then determine the position of the first slot of the first periodic signal based on the updated offset value.

[0070] For example, taking updating monitoringSlotPeriodicityAndOffset in the Search space with the subcarrier spacing SCS as an example, for example, a new slot offset information offset value may be predefined for monitoringSlotPeriodicityAndOffset in the Search space, and this predefined slot offset information offset value may be determined by directly multiplying a fixed value based on the original value, and the communication device may determine the position of the first slot of the first periodic signal based on the predefined new slot offset information offset value.

[0071] Optionally, determining the second configuration information based on the subcarrier spacing SCS includes: determining a first calculation parameter corresponding to the subcarrier spacing SCS based on the SCS, and calculating and obtaining the second configuration information based on the first calculation parameter; or The method includes determining a first mathematical relationship between the subcarrier spacing SCS and a predetermined target reference SCS based on the subcarrier spacing SCS, and calculating and obtaining the second configuration information based on the first mathematical relationship.

[0072] Alternatively, when updating the periodic allocation information based on the subcarrier spacing SCS or pre-defining the periodic allocation information based on the subcarrier spacing SCS, a first calculation parameter corresponding to the SCS may be determined based on the subcarrier spacing SCS, and the periodic allocation information may be calculated and obtained based on the first calculation parameter.

[0073] Alternatively, when updating the periodic allocation information based on the subcarrier spacing SCS or predefining the periodic allocation information based on the subcarrier spacing SCS, a first mathematical relationship between the SCS and a preset target reference SCS may be determined based on the subcarrier spacing SCS, and the periodic allocation information may be calculated and obtained based on the first mathematical relationship.

[0074] Alternatively, when updating slot offset information based on subcarrier spacing SCS or pre-defining slot offset information based on subcarrier spacing SCS, a first calculation parameter corresponding to the SCS may be determined based on the subcarrier spacing SCS, and the slot offset information may be calculated and obtained based on the first calculation parameter.

[0075] Alternatively, when updating slot offset information based on subcarrier spacing SCS or predefining slot offset information based on subcarrier spacing SCS, a first mathematical relationship between the SCS and a preset target reference SCS may be determined based on the subcarrier spacing SCS, and the slot offset information may be calculated and obtained based on the first mathematical relationship.

[0076] Alternatively, the calculation rules in this embodiment may be predefined, ie, pre-configured or predefined by a protocol.

[0077] Alternatively, one or more of the configuration information may be updated or predefined based on the same calculation method, or one or more of the configuration information may be updated or predefined based on different calculation methods, and this embodiment is not limited to this, and other information combinations may be similar.

[0078] Optionally, calculating and obtaining the second configuration information based on the first calculation parameters includes: Multiplying the original second configuration information by the first calculation parameter to obtain the second configuration information.

[0079] Optionally, when updating the periodic allocation information based on the subcarrier spacing SCS or pre-defining the periodic allocation information based on the subcarrier spacing SCS, a first calculation parameter corresponding to the SCS may be determined based on the subcarrier spacing SCS, and the original periodic allocation information may be multiplied by the first calculation parameter to obtain the periodic allocation information.

[0080] Alternatively, when updating the periodic allocation information based on the subcarrier spacing SCS or pre-defining the periodic allocation information based on the subcarrier spacing SCS, a first calculation parameter corresponding to the SCS may be determined based on the subcarrier spacing SCS, and the original slot offset information may be multiplied by the first calculation parameter to obtain the slot offset information.

[0081] For example, when updating the periodic arrangement information based on the subcarrier spacing SCS or defining the periodic arrangement information in advance based on the subcarrier spacing SCS, based on the subcarrier spacing SCS = 480 kHz, it is determined that the first calculation parameter corresponding to the SCS is 4, and the original periodic arrangement information is multiplied by 4 to obtain the periodic arrangement information in the second arrangement information. Based on the subcarrier spacing SCS = 960 kHz, it is determined that the first calculation parameter corresponding to the SCS is 8, and the original periodic arrangement information is multiplied by 8 to obtain the periodic arrangement information in the second arrangement information.

[0082] For example, when updating the slot offset information based on the subcarrier spacing SCS or defining the slot offset information in advance based on the subcarrier spacing SCS, based on the subcarrier spacing SCS = 480 kHz, it is determined that the first calculation parameter corresponding to the SCS is 4, and the original slot offset information is multiplied by 4 to obtain the slot offset information in the second arrangement information. Based on the subcarrier spacing SCS = 960 kHz, it is determined that the first calculation parameter corresponding to the SCS is 8, and the original slot offset information is multiplied by 8 to obtain the slot offset information in the second arrangement information.

[0083] Optionally, determining the first mathematical relationship between the SCS and a preset target reference SCS based on the subcarrier spacing SCS, and calculating and obtaining the second arrangement information based on the first mathematical relationship includes determining that the SCS is P times the first reference SCS preset based on the subcarrier spacing SCS and multiplying the original second arrangement information by the multiple P to obtain the second arrangement information, where 0 < P ≤ 1, or P is a positive integer.

[0084] Alternatively, when updating the periodic allocation information based on the subcarrier spacing SCS or predefining the periodic allocation information based on the subcarrier spacing SCS, it may be determined based on the subcarrier spacing SCS that the SCS is P times the preset first reference SCS, and the original periodic allocation information may be multiplied by the multiple P to obtain the periodic allocation information.

[0085] Alternatively, taking the first reference SCS=120 KHz as an example, if the subcarrier spacing BWP SCS=480 kHz, then 480 / 120=4, and therefore the original periodic allocation information may be multiplied by 4 to obtain the periodic allocation information.

[0086] Alternatively, when updating the periodic allocation information based on the subcarrier spacing SCS or predefining the periodic allocation information based on the subcarrier spacing SCS, it may be determined that the SCS is P times the preset first reference SCS based on the subcarrier spacing SCS, and the original periodic allocation information is multiplied by the multiple P to obtain the slot offset information.

[0087] Alternatively, if the first reference SCS=120 KHz is taken as an example, and the subcarrier spacing BWP SCS=480 kHz, then 480 / 120=4, so the original slot offset information can be multiplied by 4 to obtain the slot offset information.

[0088] Alternatively, the first reference SCS may be pre-set or pre-defined by a protocol.

[0089] Optionally, when the second configuration information includes periodic configuration information and / or slot offset information, predefining the second configuration information includes: This includes predefining periodicity information and / or slot offset information.

[0090] Alternatively, the periodic allocation information may be predefined, and the communication device may allocate the first periodic signal based on the predefined periodic allocation information.

[0091] Alternatively, slot offset information may be predefined, and the communication device may configure the first periodic signal based on the predefined slot offset information.

[0092] For example, taking the example of updating monitoringSlotPeriodicityAndOffset in the Search space with the subcarrier spacing SCS, for example, a new period value in monitoringSlotPeriodicityAndOffset in the Search space may be predefined, and the communication device may determine the period of the first periodic signal based on the predefined new period value.

[0093] For example, taking the case of updating monitoringSlotPeriodicityAndOffset in the Search space with the subcarrier spacing SCS as an example, for example, one new slot offset information offset value in monitoringSlotPeriodicityAndOffset in the Search space may be predefined, and the communication device may determine the position of the first slot of the first periodic signal based on the predefined new slot offset information offset value.

[0094] Alternatively, only the periodic allocation information may be predefined, only the slot offset information may be predefined, or both the periodic allocation information and the slot offset information may be predefined. This embodiment is not limited to this, and other combinations of second allocation information may be similar.

[0095] For example, the second configuration information includes period configuration information and slot offset information. Figure 4 is a schematic diagram of a signal configuration method according to an embodiment of the present application. The embodiment of the present application determines the PDCCH monitoring period and initial slot by modifying the definition of monitoringSlotPeriodicityAndOffset, and further determines the location of subsequent slot(s) based on the existing definition of Duration in the system, and determines the location of the PDCCH monitoring symbol in each slot by monitoringSymbolsWithinSlot. For example, the definition of monitoringSlotPeriodicityAndOffset may be modified, i.e., all of the period and offset information carried by monitoringSlotPeriodicityAndOffset may be multiplied by a fixed value according to a certain rule. Other parameters, such as monitoringSymbolsWithinSlot and Duration, remain unchanged.

[0096] As shown in FIG. 4, the CORESET arrangement is assumed to be as follows:

[0097] frequencyDomainResources=0001111111111--(three 0s, twelve 1s), which indicates that CORESET is offset by three PRBs from the position of PRB0, and that 12 PRBs are consecutive.

[0098] Duration=2, which indicates that this CORESET occupies two consecutive OFDM symbols.

[0099] The layout of the search space is assumed to be as follows:

[0100] monitoringSlotPeriodicityAndOffset=sl4.2, which indicates that the period of the search space is 4 slots and is offset by 2 slots.

[0101] monitoringSymbolsWithinSlot=00100000100000, which indicates that in each slot, two Occasions start from the third and ninth symbols, respectively.

[0102] Duration=2 indicates that the search space has two consecutive slots, and each slot exists.

[0103] As shown in Figure 4, when SCS = 480K, all of the period and offset information carried by monitoringSlotPeriodicityAndOffset can be multiplied by 4, and when SCS = 960K, all of the period and offset information carried by monitoringSlotPeriodicityAndOffset can be multiplied by 8 to obtain the position of the initial slot, which can be any one of the slot groups. In Figure 4, slots 9, 10, 11, and 12 are one slot group, and the initial slot can be any one of them.

[0104] Then, based on the existing definition of Duration, the position of the subsequent slot(s) can be determined, and the position of the PDCCH monitoring symbol in each slot can be determined by monitoringSymbolsWithinSlot. As shown in Figure 4, Duration = 2 indicates two slots. monitoringSymbolsWithinSlot = 00100000100000 indicates that two Occasions start from the third and ninth symbols in each slot, respectively.

[0105] Optionally, when the second allocation information includes symbol position allocation information, determining the second allocation information based on a subcarrier spacing SCS includes: determining a value of the symbol position alignment information after adding M zeros after each symbol based on a value corresponding to original symbol position alignment information of the first periodic signal; Here, M is a first fixed value, and the first fixed value is determined based on the subcarrier spacing SCS.

[0106] Optionally, when the second alignment information includes symbol position alignment information, the value of the symbol position alignment information may be determined based on a value corresponding to the original symbol position alignment information of the first periodic signal after adding M zeros after each symbol, where M is a first fixed value determined based on the subcarrier spacing SCS.

[0107] Alternatively, when the second allocation information includes periodic allocation information, the communication device may update the symbol position allocation information based on the subcarrier spacing SCS, or may predefine the symbol position allocation information based on the subcarrier spacing SCS, and the communication device uses the predefined symbol position allocation information when allocating the first periodic signal.

[0108] Optionally, determining the first fixed value based on the subcarrier spacing SCS includes: obtaining the first fixed value based on a subcarrier spacing SCS; or and predefining the first fixed value based on a subcarrier spacing SCS.

[0109] Alternatively, the updating or predefining of the symbol position allocation information is based on a first fixed value, so that when the second allocation information includes symbol position allocation information, the communication device may update the first fixed value M based on the subcarrier spacing SCS, or may predefine the first fixed value M based on the subcarrier spacing SCS, and when allocating the first periodic signal, the communication device determines the symbol position allocation information using the predefined M.

[0110] Optionally, determining the first fixed value based on the subcarrier spacing SCS includes: determining a first fixed value corresponding to a subcarrier spacing SCS based on the SCS; or The method includes determining a second mathematical relationship between the SCS and a predetermined target reference SCS based on the subcarrier spacing SCS, and calculating and obtaining the first fixed value based on the second mathematical relationship.

[0111] Alternatively, the first fixed value may be updated based on the subcarrier spacing SCS, and the symbol position allocation information may be updated accordingly; or when the first fixed value is predefined based on the subcarrier spacing SCS, the first fixed value corresponding to the SCS may be determined based on the subcarrier spacing SCS, and the symbol position allocation information may be determined accordingly.

[0112] For example, when updating the first fixed value based on the subcarrier spacing SCS and further updating the symbol position arrangement information or predefining the first fixed value based on the subcarrier spacing SCS, it can be determined that the first fixed value corresponding to the SCS is 3 when the subcarrier spacing SCS is 480 kHz, or 7 when the subcarrier spacing SCS is 960 kHz.

[0113] Alternatively, when updating the first fixed value based on the subcarrier spacing SCS or predefining the first fixed value based on the subcarrier spacing SCS, a second mathematical relationship between the SCS and a preset target reference SCS may be determined based on the subcarrier spacing SCS, and the first fixed value may be calculated and obtained based on the second mathematical relationship, and symbol position configuration information may also be obtained.

[0114] Alternatively, the calculation rules in this embodiment may be predefined, ie, pre-configured or predefined by a protocol.

[0115] Optionally, determining a second mathematical relationship between the subcarrier spacing SCS and a preset target reference SCS based on the subcarrier spacing SCS, and calculating and obtaining the first fixed value based on the second mathematical relationship may include: Determine, based on the subcarrier spacing SCS, that a quotient between the SCS and a predetermined second reference SCS is R (R is a positive integer); and subtracting 1 from R to obtain the first fixed value.

[0116] Alternatively, when updating the first fixed value based on the subcarrier spacing SCS and further updating the symbol position allocation information, or pre-defining the first fixed value based on the subcarrier spacing SCS, determining that the quotient between the SCS and a preset second reference SCS is R based on the subcarrier spacing SCS, and subtracting 1 from R to obtain the first fixed value and further obtaining the symbol position allocation information.

[0117] For example, when updating the first fixed value based on the subcarrier spacing SCS and then updating the symbol position allocation information, or when pre-defining the first fixed value based on the subcarrier spacing SCS, taking the second reference SCS=120 KHz as an example, if the subcarrier spacing BWP SCS=480 kHz, then 480 / 120-1=3, so the first fixed value is determined to be 3, and further symbol position allocation information can be determined; if the subcarrier spacing BWP SCS=960 kHz, then 960 / 120-1=7, so the first fixed value is determined to be 7, and further symbol position allocation information can be determined.

[0118] For example, the second configuration information includes symbol position configuration information. Figure 5 is a second schematic diagram of a signal configuration method according to an embodiment of the present application. It should be noted that the embodiment of the present application can determine the PDCCH monitoring period and initial slot by defining monitoringSlotPeriodicityAndOffset, where monitoringSlotPeriodicityAndOffset may be pre-defined or updated based on the SCS, or may be directly pre-defined or may not be changed. The embodiment of the present application may directly identify the monitoring symbol(s) in each PDCCH monitoring slot by modifying the definition of monitoringSymbolsWithinSlot.

[0119] As shown in FIG. 5, the CORESET arrangement is assumed to be as follows:

[0120] frequencyDomainResources=0001111111111--(three 0s, twelve 1s), which indicates that CORESET is offset by three PRBs from the position of PRB0, and that 12 PRBs are consecutive.

[0121] Duration=2, which indicates that this CORESET occupies two consecutive OFDM symbols.

[0122] The layout of the search space is assumed to be as follows:

[0123] monitoringSlotPeriodicityAndOffset=sl4.2, which indicates that the period of the search space is 4 slots and is offset by 2 slots.

[0124] monitoringSymbolsWithinSlot=00100000100000, which indicates that in each slot, two Occasions start from the third and ninth symbols, respectively.

[0125] Duration=2 indicates that the search space has two consecutive slots, and each slot exists.

[0126] As shown in FIG. 5, slots 9, 10, 11, and 12 of the SCS480 correspond to slot 3 of the SCS120, and slots 13, 14, 15, and 16 of the SCS480 correspond to slot 4 of the SCS120.

[0127] The following two methods are both applicable to the embodiments of the present application.

[0128] a) Only modify the monitoringSymbolsWithinSlot definition, that is, the second configuration information only includes symbol position configuration information.

[0129] The definition of monitoringSymbolsWithinSlot is directly modified. For example, if monitoringSymbolsWithinSlot=00100000100000 is set in the existing protocol, then by default a first fixed number of zeros will be added after each symbol in monitoringSymbolsWithinSlot. At this time, the definition of monitoringSymbolsWithinSlot is at the symbol level.

[0130] For example, if BWP SCS=480kHz and monitoringSymbolsWithinSlot=00100000100000, add three zeros after each symbol in each monitoringSymbolsWithinSlot to get monitoringSymbolsWithinSlot=00000000100000000000000000000000001000000000000000000000000000000, and the search space that needs to be monitored is at the symbol corresponding to a value of 1. Then, an offset value can be added based on this.

[0131] b) The second arrangement information includes symbol position arrangement information and duration information.

[0132] Alternatively, the first fixed value may be predefined by the protocol, for example by default adding three zeros when SCS=480K, adding seven zeros when SCS=960K, or setting one reference SCS, for example SCS=120K, dividing the SCS of the BWP by this reference SCS and subtracting one from the resulting value to determine the number of zeros that need to be added.

[0133] It should be noted that the offset value may be slot-based or symbol-based. In the above example, the offset value is 0.

[0134] It should be noted that the two solutions listed above are merely examples of the embodiments of the present application, and are not intended to limit the embodiments of the present application.

[0135] Optionally, when the second arrangement information includes symbol position arrangement information, predefining the second arrangement information includes: determining a value of the symbol position alignment information after adding N zeros after each symbol based on a value corresponding to the original symbol position alignment information of the first periodic signal; Here, N is a second fixed value, which is predefined.

[0136] Alternatively, a second fixed value N may be directly predefined, and the value of the symbol position alignment information may be determined based on the value corresponding to the original symbol position alignment information of the first periodic signal after adding N zeros after each symbol.

[0137] Optionally, when the second configuration information includes duration information, determining the second configuration information based on a subcarrier spacing SCS includes: determining a slot spacing between slots based on the subcarrier spacing SCS; determining the duration information based on the inter-slot time interval and the slot interval; Here, the time interval between the slots is determined based on the original duration information of the first periodic signal.

[0138] Optionally, when the second configuration information includes duration information, after determining the slot intervals between slots based on the subcarrier spacing SCS, the duration information may be determined by combining the time intervals between the slots to configure the first periodic signal.

[0139] Taking the duration information as an example where the duration information is the duration in the search space, the time interval between slots may be determined based on the original duration information of the first periodic signal. For example, if it is determined that the first periodic signal originally exists on two consecutive slots and has a duration of 2 ms, then duration information M can be determined based on an updated or predefined slot interval while keeping the duration of 2 ms unchanged (this may be understood as meaning that the search space that needs to be monitored appears in M ​​slots, and the interval between every two search spaces is the determined slot interval), i.e., the position of other slot(s) of the first periodic signal can be determined.

[0140] Optionally, determining a slot spacing between slots based on the subcarrier spacing SCS includes: obtaining the slot spacing based on a subcarrier spacing SCS; or The method includes predefining the slot spacing based on a subcarrier spacing SCS.

[0141] Alternatively, the updating or predefining of the duration information is updating or predefining based on the slot interval, so that when the second configuration information includes duration information, the communication device may update the slot interval based on the subcarrier spacing SCS or predefine the slot interval based on the subcarrier spacing SCS, and when configuring the first periodic signal, the communication device determines the duration information using the slot interval based on the predefinition.

[0142] Optionally, determining a slot spacing between slots based on the subcarrier spacing SCS includes: determining a slot spacing corresponding to a subcarrier spacing SCS based on the SCS; or The method includes determining a third mathematical relationship between the subcarrier spacing SCS and a preset target reference SCS based on the subcarrier spacing SCS, and calculating and obtaining the slot spacing based on the third mathematical relationship.

[0143] Alternatively, the slot interval may be updated based on the subcarrier spacing SCS, and the duration information may be updated accordingly; or when the slot interval is predefined based on the subcarrier spacing SCS, the duration information corresponding to the SCS may be determined based on the subcarrier spacing SCS, and the duration information may be determined accordingly.

[0144] For example, when updating the slot interval based on the subcarrier spacing SCS and further updating the duration information, or predefining the slot interval based on the subcarrier spacing SCS, it can be determined that the slot interval corresponding to the SCS is 4 when the subcarrier spacing SCS is 480 kHz, or that the slot interval corresponding to the SCS is 8 when the subcarrier spacing SCS is 960 kHz.

[0145] Alternatively, when updating the slot interval based on the subcarrier spacing SCS and further updating the duration information, or when predefining the slot interval based on the subcarrier spacing SCS, a third mathematical relationship between the SCS and a preset target reference SCS may be determined based on the subcarrier spacing SCS, and the slot interval may be calculated and obtained based on the third mathematical relationship, and further the duration information may be obtained.

[0146] Alternatively, the calculation rules in this embodiment may be predefined, ie, pre-configured or predefined by a protocol.

[0147] Optionally, determining a third mathematical relationship between the subcarrier spacing SCS and a preset target reference SCS based on the subcarrier spacing SCS, and calculating and obtaining the slot spacing based on the third mathematical relationship may include: Determine, based on the subcarrier spacing SCS, that a quotient between the SCS and a predetermined third reference SCS is L (L is a positive integer); and determining that the slot interval is L.

[0148] Alternatively, the slot interval may be updated based on the subcarrier spacing SCS, and the duration information may be updated. Alternatively, when the slot interval is predefined based on the subcarrier spacing SCS, it may be determined that the quotient between the SCS and a preset second reference SCS is L based on the subcarrier spacing SCS, and the slot interval may be determined to be L, and the duration information may be obtained.

[0149] For example, when updating the slot spacing based on the subcarrier spacing SCS and then updating the duration information, or pre-defining the slot spacing based on the subcarrier spacing SCS, taking the third reference SCS=120 KHz as an example, if the subcarrier spacing BWP SCS=480 kHz, then 480 / 120=4, so the slot spacing can be determined to be 4 and the duration information can be determined. If the subcarrier spacing BWP SCS=960 kHz, then 960 / 120=8, so the slot spacing can be determined to be 8 and the duration information can be determined.

[0150] For example, the second configuration information includes duration information. Figure 6 is a third schematic diagram of a signal configuration method according to an embodiment of the present application. It should be noted that the embodiment of the present application can determine the period and initial slot of PDCCH monitoring by defining monitoringSlotPeriodicityAndOffset, which may be pre-defined or updated based on the SCS, or may be pre-defined directly or may not be changed. The embodiment of the present application can determine the position of subsequent slot(s) by modifying the definition of Duration, and determine the position of PDCCH monitoring symbol in each slot by monitoringSymbolsWithinSlot.

[0151] As shown in FIG. 6, the arrangement of CORESET is assumed to be as follows:

[0152] frequencyDomainResources=000111111 1111--(three 0s, twelve 1s), which indicates that CORESET is offset by three PRBs from the position of PRB0, and that 12 PRBs are consecutive.

[0153] Duration=2, which indicates that this CORESET occupies two consecutive OFDM symbols.

[0154] The layout of the search space is assumed to be as follows:

[0155] monitoringSlotPeriodicityAndOffset=sl4.2, which indicates that the period of the search space is 4 slots and is offset by 2 slots.

[0156] monitoringSymbolsWithinSlot=00100000100000, which indicates that in each slot, two Occasions start from the third and ninth symbols, respectively.

[0157] Duration=2 indicates that the search space has two consecutive slots, and each slot exists.

[0158] As shown in FIG. 6, slots 9, 10, 11, and 12 with SCS=480 kHz correspond to slot 3 with SCS=120 kHz, and slots 13, 14, 15, and 16 with SCS=480 kHz correspond to slot 4 with SCS=120 kHz.

[0159] The following two methods are applied to this embodiment.

[0160] Scheme c) is a scheme for modifying only the duration definition, that is, the second configuration information only includes duration information.

[0161] Alternatively, the duration definition can be directly modified, for example, by setting duration=M. In this case, by default, the search spaces to be monitored appear in M ​​slots, and each slot is separated by a second fixed number of slots. That is, after modifying the duration definition, the second fixed number of slots may appear between the search spaces that originally appeared consecutively in slot 3 and slot 4. Therefore, the positions of these two search spaces change to slot 9 and slot 13, but the time interval between these two search spaces remains the same.

[0162] Scheme d), the second configuration information includes duration information, period configuration information and slot offset information.

[0163] Alternatively, multiple time domain positions of the search space may be identified in conjunction with the updated or predefined content of monitoringSlotPeriodicityAndOffset. As shown in Figure 6, the periodic arrangement in monitoringSlotPeriodicityAndOffset may be updated or predefined, and the offset and duration indication domain values ​​in monitoringSlotPeriodicityAndOffset may be combined to identify multiple time domain positions of the search space, i.e., (offset + duration {0,1...n}) * fixed value + offset value.

[0164] As described in methods c) and d), the slot interval may be called a second fixed value, which may be predefined by the protocol, for example, by default, multiplying by 4 when SCS=480kHz, and by 8 when SCS=960kHz. Or, a reference SCS may be set, for example, SCS=120kHz, and the SCS of the BWP may be divided by this reference SCS, and the resulting value may be the value by which it needs to be multiplied.

[0165] It should be noted that the two solutions listed above are merely examples of the embodiments of the present application, and are not intended to limit the embodiments of the present application.

[0166] It should be noted that the offset value may be based on the number of slots or symbols.

[0167] Optionally, the offset value is zero.

[0168] Optionally, when the second configuration information includes duration information, predefining the second configuration information includes: predefining slot intervals between slots; determining the duration information based on the inter-slot time interval and the slot interval; Here, the time interval between the slots is determined based on the original duration information of the first periodic signal.

[0169] Optionally, when the second configuration information includes duration information, a slot interval between slots may be predefined, and the duration information may be determined based on the time interval between the slots and the slot interval, where the time interval between the slots is determined based on the original duration information of the first periodic signal.

[0170] Optionally, when the second arrangement information includes periodic arrangement information, arranging the first periodic signal based on the first arrangement information includes: Determining the period of the first periodic signal based on period allocation information in second allocation information.

[0171] Optionally, the period of the first periodic signal may be obtained directly based on the value of the period placement information, or may be obtained after updating.

[0172] For example, the periodicity allocation information is monitoringSlotPeriodicityAndOffset in the Search space. The periodicity of the first periodic signal may be directly obtained based on the periodicity value in monitoringSlotPeriodicityAndOffset, or may be obtained after updating.

[0173] Optionally, when the second configuration information includes slot offset information, configuring the first periodic signal based on the first configuration information includes: Determining a position of a target slot of the first periodic signal based on slot offset information in second configuration information.

[0174] Optionally, after determining the periods of the first periodic signal, the position of a target slot, for example the first slot, in each period may be determined.

[0175] Alternatively, the target slot may be a predefined slot, for example the first slot or the last slot of the first periodic signal.

[0176] Optionally, the position of the target slot of the first periodic signal may be obtained directly based on the slot offset information, or may be obtained after updating.

[0177] For example, the periodic allocation information is an offset in monitoringSlotPeriodicityAndOffset in the Search space. The position of the target slot of the first periodic signal may be obtained directly based on the value of the offset in monitoringSlotPeriodicityAndOffset, or may be obtained after updating.

[0178] Optionally, when the second configuration information includes duration information, configuring the first periodic signal based on the first configuration information includes: The method includes determining a time interval between slots of the first periodic signal based on duration information in the second configuration information, and determining the position of another slot based on the time interval, wherein the other slot includes a slot other than the target slot.

[0179] Alternatively, after determining the position of the target slot in each cycle, for example the position of the first slot, the positions of other slot(s) may be determined.

[0180] Alternatively, the target slot may be a predefined slot, for example the first slot of the first periodic signal, and the other slots may be subsequent slot(s) of the first periodic signal.

[0181] Optionally, the time interval between slots of the first periodic signal may be determined based on the duration information in the second configuration information, and the time interval may be further divided by the time length of each slot, thus obtaining the positions of other slots relative to the first slot.

[0182] Optionally, when the second arrangement information includes symbol position arrangement information, arranging the first periodic signal based on the first arrangement information includes: Determining the symbol position at which the first periodic signal is present in each slot based on the symbol position allocation information in the second allocation information.

[0183] Optionally, after determining the target slot and other slot(s) for each period, the symbol position in which this signal resides in each slot may be determined.

[0184] Alternatively, when the second arrangement information includes symbol position arrangement information, the symbol positions at which the first periodic signal is present in each slot may be determined directly based on the symbol position arrangement information in the second arrangement information, or the symbol positions at which the first periodic signal is present in each slot after updating may be determined.

[0185] Optionally, the first period information is A search space in PDCCH, a channel state information reference signal CSI-RS; a tracking reference signal TRS; a received signal strength indication RSSI; Synchronization signal block measurement sequence allocation information SSB-MTC; Scheduling request information; and a sounding reference signal (SRS).

[0186] Optionally, the first periodic information includes at least one of a search space in the PDCCH, a channel state information reference signal CSI-RS, a tracking reference signal TRS, a received signal strength indication RSSI, synchronization signal block measurement sequence configuration information SSB-MTC, scheduling request information, and a sounding reference signal SRS, but is not limited thereto.

[0187] Optionally, at least one of the periodic signals may be simultaneously arranged according to the method according to each embodiment of the present application.

[0188] In the embodiments of the present application, by determining the allocation information of the periodic signal based on the subcarrier spacing SCS and / or predefining the allocation information of the first periodic signal, more appropriate resource allocation for the periodic signal can be performed, thereby realizing adaptation to the allocation of periodic signals in the case of multiple types of subcarrier spacing, thereby reducing the blind detection complexity of the terminal and lowering the requirements for the data processing capability of the terminal.
