As long as the same technical effect is achieved, the base station is not limited to a specific technical vocabulary. It should be noted that in the embodiment of the present application, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

[0039] In order to better understand the embodiments of the present application, the following contents are first introduced:

[0040] (1) Frame structure;

[0041] In order to support various frequency bands and deployment scenarios, New Radio (NR) supports flexible numerology configuration. A numerology (denoted by μ) corresponds to a subcarrier spacing configuration (and cyclic prefix length) in the frequency domain. In NR, a variety of different numerologies are defined by multiplying the basic subcarrier spacing (15kHz) by an integer N (i.e., expanding it by N times. N=2n, where n is an integer). As shown in Table 1 below:

[0042] Table 1 Frame structure parameter set

[0043]

[0044] As shown in Table 1, as the SCS increases, the number of slots contained in each subframe increases exponentially, while the time occupied by each slot decreases exponentially.

[0045] (2) Periodic signal

[0046] There are many signals in NR, some of which are periodically configured, that is, the period, offset value, number of continuous slots, and number of symbols in a single slot of the signal are given in the configuration parameters. Through the above configuration, the base station or UE is informed where to find the required signal.

[0047] This type of periodic signals 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), TRS resource configuration, RSSI (Receiver signal Strength indicator), SSB-MTC (measurement timing configuration), Dedicated scheduling request (SchedulingRequestResourceConfigdetermines physical layer resources on PUCCH where the UE may send the dedicated scheduling request), SRS resource configuration, etc.

[0048] Take the search space configuration in PDCCH as an example:

[0049] (3)PDCCH

[0050] PDCCH is a downlink control channel, carrying the control information of the uplink physical shared channel (Physical Uplink Shared Channel, PUSCH) and the downlink shared physical channel (Physical Downlink Share Channel, PDSCH) Downlink Control Information (Downlink Control Information, DCI). In Long Term Evolution (Long Term Evolution, LTE), PDCCH occupies the entire bandwidth in the frequency domain and the first 1-3 symbols of each subframe in the time domain. In NR, if PDCCH continues to occupy the entire bandwidth in the LTE way, it will undoubtedly be a waste of resources, and it will put forward high requirements on the user equipment (User Equipment, UE) (the terminal is taken as an example in each embodiment of the present application), which is not conducive to reducing the terminal cost. Therefore, the PDCCH in NR will be in the bandwidth part (Band Width Part, BWP), and the time domain does not occupy some fixed time slots. The PDCCH time-frequency resources in NR are mainly determined by: control resource set (control-resource set, CORESET) and search space.

[0051] (4) CORESET;

[0052] CORESET solves the problem of PDCCH existence range, such as time domain length and frequency domain range. Since NR has a large system bandwidth (up to 400M), if the static configuration method of LTE (occupying the entire system bandwidth) is used, the blind detection complexity will be greatly increased. Therefore, NR can use a configurable CORESET, and the time domain length and frequency domain range of CORESET can be configured through system information or Dedicated Radio Resource Control (RRC) messages.

[0053] The specific meanings of the configuration parameters involved in the RRC configuration are as follows in Table 2:

[0054] Table 2 CORESET configuration parameters

[0055]

[0056]

[0057] From the RRC signaling, we can see that the configuration of CORESET does not specify the specific time domain position (but only gives the time domain duration (number of symbols)), and the specific time domain position is given by Search Space. This design can achieve greater flexibility. CORESET can be configured at any frequency domain position (the configuration parameter FrequencyDomainResources IE is the Bitmap of the PRB number of the current BWP).

[0058] (5)Search space;

[0059] Search Space solves the problem of how UE searches. There is a similar concept in LTE, and its purpose is to reduce the blind detection complexity of UE as much as possible. Unlike LTE, the search space in NR is targeted at a certain CORESET. NR can configure different Search Spaces for different UEs, that is, different blind detection methods are configured for different UEs (such as monitoring period, monitoring symbol starting position, etc.). In this way, the blind detection complexity of UE can be further reduced.

[0060] The specific meanings of the configuration parameters involved in the RRC configuration are as follows in Table 3:

[0061] Table 3 Search space configuration parameters

[0062]

[0063] Assume that the CORESET configuration is as follows:

[0064] frequencyDomainResources=00011111111111——(3 0s, 12 1s): represents that the position of CORESET is 3 PRBs lower than PRB0, and there are 12 consecutive PRBs.

[0065] Duration = 2: indicates that this CORESET occupies 2 consecutive OFDM symbols.

[0066] Assume that the Search space is configured as follows:

[0067] monitoringSlotPeriodicityAndOffset=sl4.2: indicates that the period of the Search space is 4 slots and the offset is 2 slots.

[0068] monitoringSymbolsWithinSlot=00100000100000: represents that in each slot, there are two Occasions starting from the 3rd symbol and the 9th symbol respectively.

[0069] Duration = 2 means that the search space has two consecutive slots and each slot exists.

[0070] Figure 2 is a schematic diagram of the signal configuration provided in the embodiment of the present application, such as Figure 2 The figure shows the signal configuration diagram according to the above CORESET and Search space.

[0071] The signal configuration method and device provided in the embodiments of the present application are described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0072] Figure 3 is a flow chart of the signal configuration method provided in the embodiment of the present application, such as Figure 3 As shown, the method comprises the steps of:

[0073] Step 300, the communication device configures the first periodic signal based on the first configuration information;

[0074] The second configuration information in the first configuration information is determined based on the subcarrier spacing SCS, and / or the second configuration information in the first configuration information is predefined;

[0075] The first configuration information includes:

[0076] Periodic configuration information;

[0077] Time slot offset information;

[0078] Duration information; and

[0079] Symbol location configuration information.

[0080] Optionally, the communication device may be a terminal.

[0081] Optionally, the communication device may be a network side device.

[0082] Optionally, in order to overcome the problem that the use of a large SCS will result in a smaller maximum period supported by it, the configuration information of the periodic signal may be redefined or updated.

[0083] Optionally, the configuration information of the periodic signal may be redefined or updated based on the value of the SCS.

[0084] Optionally, the first configuration information is information required to configure the first periodic signal.

[0085] Optionally, the second configuration information is part or all of the configuration information that is redefined or updated based on the value of the SCS, or part or all of the configuration information may be directly predefined.

[0086] Optionally, in the B52.6GHz system, a large subcarrier spacing (SCS) can be introduced, such as SCS = 480K / 960K. Therefore, the number of slots contained in a subframe may increase, while the time occupied by each slot is very small. At this time, based on the capabilities of the UE, that is, considering the blind detection complexity of the UE and the ability of the UE to process data, some short-period configurations in the search space may not be applicable in many periodic signals, such as configurations with a period of 1, 2 or 4 slots. If a long-period configuration is used, such as a period of 80 slots, the offset configuration requires 7 bits to implement (27 = 128> 80), and its overhead accounts for a large proportion. In addition, the existing configuration supports a maximum period of 2560 slots, which is 320ms for SCS = 120K. If a larger SCS is used, such as SCS = 960K, it is still 40ms with a period of 2560 slots. Therefore, using a larger SCS will result in a smaller maximum period supported by it.

[0087] Therefore, in order to overcome the above defects, part or all of the configuration information may be redefined or updated based on the value of the SCS, or part or all of the configuration information may be directly predefined.

[0088] Optionally, the communication device can configure the first periodic signal based on periodic configuration information, time slot offset information, duration information, and symbol position configuration information; wherein all or part of the configuration information (i.e., the second configuration information) is determined based on the subcarrier spacing SCS, and / or all or part of the configuration information (i.e., the second configuration information) is predefined.

[0089] Optionally, the first periodic signal is a signal of any periodic configuration, that is, the period, offset value, number of continuous slots, and number of symbols occupied in a single slot of the signal are given in the configuration parameters.

[0090] In an embodiment of the present application, by determining the configuration information of the periodic signal based on the subcarrier spacing SCS and / or predefining the configuration information of the first periodic signal, it is possible to achieve more appropriate resource configuration for the periodic signal, adapt to the configuration of the periodic signal under various subcarrier spacing conditions, reduce the blind detection complexity of the terminal, and reduce the requirements for the terminal's ability to process data.

[0091] Optionally, the second configuration information includes at least one of the following:

[0092] Periodic configuration information;

[0093] Time slot offset information;

[0094] Duration information;

[0095] Symbol location configuration information.

[0096] Optionally, all or part of the information of the configuration periodic signal may be predefined or updated, so the second configuration information may include any one of the following items or a combination thereof:

[0097] Periodic configuration information;

[0098] Time slot offset information;

[0099] Duration information;

[0100] Symbol location configuration information.

[0101] Optionally, only one or more of the configuration information may be updated or predefined, or only another one or more of the configuration information may be updated or predefined, or multiple types of the information may be updated or predefined simultaneously.

[0102] For example, only the period configuration information may be updated or predefined, only the time slot offset information may be updated or predefined, or both the period configuration information and the time slot offset information may be updated or predefined. This embodiment does not limit this, and the same applies to other combinations of the second configuration information.

[0103] Optionally, one or more configuration information may be updated or predefined in the same manner, or may be updated or predefined in different manners. One or more configuration information may also be predefined, and then one or more of the same or different configuration information may be updated during signal configuration. This embodiment does not impose any restrictions on this.

[0104] For example, the period configuration information and time slot offset information may be updated or predefined in the same manner, or may be updated or predefined based on different methods. The period configuration information may be predefined and the time slot offset information may be updated during signal configuration, or the time slot offset information may be predefined and the period configuration information may be updated during signal configuration. This embodiment does not impose any restrictions on this, and the same applies to other combinations of the second configuration information.

[0105] In the embodiment of the present application, multiple possibilities of updating or predefining the second configuration information used to configure the periodic signal are provided, so that the periodic signal can be configured more flexibly.

[0106] Optionally, when the second configuration information includes period configuration information and / or time slot offset information, determining the second configuration information based on the subcarrier spacing SCS includes:

[0107] Update the second configuration information based on the subcarrier spacing SCS; or

[0108] The second configuration information is predefined based on the subcarrier spacing SCS.

[0109] Optionally, the periodic configuration information and / or time slot offset information may be updated or redefined, that is, when the second configuration information includes the periodic configuration information and / or time slot offset information, the communication device may update the second configuration information based on the subcarrier spacing SCS, or the communication device may predefine the second configuration information based on the subcarrier spacing SCS.

[0110] Optionally, the communication device may update the second configuration information based on the subcarrier spacing SCS when configuring the first periodic signal, that is, update the periodic configuration information and / or time slot offset information.

[0111] Optionally, before configuring the first periodic signal, the system can pre-set or the protocol can pre-define second configuration information associated with the subcarrier spacing SCS. When configuring the first periodic signal, the communication device can directly use the predefined second configuration information, that is, update the periodic configuration information and / or time slot offset information.

[0112] Optionally, when the second configuration information includes period configuration information, the communication device may update the period configuration information based on the subcarrier spacing SCS, or may predefine the period configuration information based on the subcarrier spacing SCS, and the communication device uses the predefined period configuration information when configuring the first periodic signal.

[0113] Optionally, when the second configuration information includes time slot offset information, the communication device may update the time slot offset information based on the subcarrier spacing SCS, or may predefine the time slot offset information based on the subcarrier spacing SCS, and the communication device uses the predefined time slot offset information when configuring the first periodic signal.

[0114] For example, taking the subcarrier spacing SCS to update the monitoringSlotPeriodicityAndOffset in the Search space as an example, when the communication device configures the first periodic signal, the value of the period in the monitoringSlotPeriodicityAndOffset in the Search space is directly multiplied by a fixed value based on the original configuration value to obtain an updated value. The period of the first periodic signal can be determined based on the updated period value.

[0115] For example, taking the subcarrier spacing SCS to update the monitoringSlotPeriodicityAndOffset in the Search space as an example, a new period value in the monitoringSlotPeriodicityAndOffset in the Search space can be predefined. The value of the predefined period can be determined by directly multiplying a fixed value based on the original value. The communication device can determine the period of the first periodic signal based on the predefined new period value.

[0116] For example, taking the subcarrier spacing SCS to update the monitoringSlotPeriodicityAndOffset in the Search space as an example, when the communication device configures the first periodic signal, the time slot offset information offset in the monitoringSlotPeriodicityAndOffset in the Search space is directly multiplied by a fixed value based on the original configuration value to obtain an updated value. The position of the first slot of the first periodic signal can be determined based on the updated offset value.

[0117] For example, taking the updating of monitoringSlotPeriodicityAndOffset in the Search space by the subcarrier spacing SCS as an example, a new time slot offset information offset value in the monitoringSlotPeriodicityAndOffset in the Search space can be predefined. The predefined time slot offset information offset value can be determined by directly multiplying a fixed value on the basis of the original value. The communication device can determine the position of the first slot of the first periodic signal based on the predefined new time slot offset information offset value.

[0118] Optionally, the determining the second configuration information based on the subcarrier spacing SCS includes:

[0119] Based on the subcarrier spacing SCS, determine a first calculation parameter corresponding to the SCS, and calculate and obtain the second configuration information based on the first calculation parameter; or

[0120] Based on the subcarrier spacing SCS, a first mathematical relationship between the SCS and a preset target reference SCS is determined, and based on the first mathematical relationship, the second configuration information is calculated and obtained.

[0121] Optionally, when updating period configuration information based on subcarrier spacing SCS, or predefining period configuration information based on subcarrier spacing SCS, a first calculation parameter corresponding to the SCS can be determined based on the subcarrier spacing SCS, and the period configuration information can be calculated based on the first calculation parameter.

[0122] Optionally, when updating period configuration information based on subcarrier spacing SCS, or predefining period configuration information based on subcarrier spacing SCS, a first mathematical relationship between the SCS and a preset target reference SCS can be determined based on the subcarrier spacing SCS, and the period configuration information can be calculated based on the first mathematical relationship.

[0123] Optionally, when updating the time slot offset information based on the subcarrier spacing SCS, or predefining the time slot offset information based on the subcarrier spacing SCS, a first calculation parameter corresponding to the SCS can be determined based on the subcarrier spacing SCS, and the time slot offset information can be calculated based on the first calculation parameter.

[0124] Optionally, when updating the time slot offset information based on the subcarrier spacing SCS, or predefining the time slot offset information based on the subcarrier spacing SCS, the first mathematical relationship between the SCS and a preset target reference SCS can be determined based on the subcarrier spacing SCS, and the time slot offset information can be calculated based on the first mathematical relationship.

[0125] Optionally, the calculation rule in this embodiment may be predefined, that is, may be preconfigured or predefined by a protocol.

[0126] Optionally, one or more configuration information may be updated or predefined based on the same calculation method, or may be updated or predefined based on different calculation methods. This embodiment does not limit this, and the same applies to other combinations of information.

[0127] Optionally, the calculating and obtaining the second configuration information based on the first calculation parameter includes:

[0128] The original second configuration information is multiplied by the first calculation parameter to obtain the second configuration information.

[0129] Optionally, when updating the period configuration information based on the subcarrier spacing SCS, or predefining the period configuration information based on the subcarrier spacing SCS, the first calculation parameter corresponding to the SCS can be determined based on the subcarrier spacing SCS, and the original period configuration information can be multiplied by the first calculation parameter to obtain the period configuration information.

[0130] Optionally, when updating period configuration information based on subcarrier spacing SCS, or predefining period configuration information based on subcarrier spacing SCS, a first calculation parameter corresponding to the SCS can be determined based on the subcarrier spacing SCS, and the original time slot offset information can be multiplied by the first calculation parameter to obtain the time slot offset information.

[0131] For example, when updating the period configuration information based on the subcarrier spacing SCS, or predefining the period configuration information based on the subcarrier spacing SCS, the first calculation parameter corresponding to the SCS can be determined to be 4 based on the subcarrier spacing SCS=480kHz, and the original period configuration information can be multiplied by 4 to obtain the period configuration information in the second configuration information. The first calculation parameter corresponding to the SCS can be determined to be 8 based on the subcarrier spacing SCS=960kHz, and the original period configuration information can be multiplied by 8 to obtain the period configuration information in the second configuration information.

[0132] For example, when updating the time slot offset information based on the subcarrier spacing SCS, or predefining the time slot offset information based on the subcarrier spacing SCS, the first calculation parameter corresponding to the SCS can be determined to be 4 based on the subcarrier spacing SCS=480kHz, and the original time slot offset information can be multiplied by 4 to obtain the time slot offset information in the second configuration information. The first calculation parameter corresponding to the SCS can be determined to be 8 based on the subcarrier spacing SCS=960kHz, and the original time slot offset information can be multiplied by 8 to obtain the time slot offset information in the second configuration information.

[0133] Optionally, the determining, based on the subcarrier spacing SCS, a first mathematical relationship between the SCS and a preset target reference SCS, and calculating and obtaining the second configuration information based on the first mathematical relationship includes:

[0134] Based on the subcarrier spacing SCS, determining that the SCS is P times a preset first reference SCS;

[0135] Multiplying the original second configuration information by the multiple P to obtain the second configuration information;

[0136] Wherein, 0<P≤1, or, P is a positive integer.

[0137] Optionally, when updating the period configuration information based on the subcarrier spacing SCS, or predefining the period configuration information based on the subcarrier spacing SCS, it is possible to determine P times the first reference SCS preset by the SCS based on the subcarrier spacing SCS, and multiply the original period configuration information by the multiple P to obtain the period configuration information.

[0138] Optionally, taking the first reference SCS=120KHz as an example, if the subcarrier spacing BWP SCS=480kHz, 480 / 120=4, the original period configuration information may be multiplied by 4 to obtain the period configuration information.

[0139] Optionally, when updating the period configuration information based on the subcarrier spacing SCS, or predefining the period configuration information based on the subcarrier spacing SCS, it is possible to determine P times the first reference SCS preset by the SCS based on the subcarrier spacing SCS, multiply the original period configuration information by the multiple P, and obtain the time slot offset information.

[0140] Optionally, taking the first reference SCS=120KHz as an example, if the subcarrier spacing BWP SCS=480kHz, 480 / 120=4, the original time slot offset information can be multiplied by 4 to obtain the time slot offset information.

[0141] Optionally, the first reference SCS may be pre-set or pre-specified by protocol.

[0142] Optionally, when the second configuration information includes period configuration information and / or time slot offset information, predefining the second configuration information includes:

[0144] Optionally, period configuration information may be predefined, and when configuring the first periodic signal, the communication device may perform configuration based on the predefined period configuration information.

[0145] Optionally, time slot offset information may be predefined, and when configuring the first periodic signal, the communication device may perform configuration based on the predefined time slot offset information.

[0146] For example, taking the subcarrier spacing SCS to update the monitoringSlotPeriodicityAndOffset in the Search space as an example, a new period value in the monitoringSlotPeriodicityAndOffset in the Search space can be predefined, and the communication device can determine the period of the first periodic signal based on the predefined new period value.

[0147] For example, taking the subcarrier spacing SCS to update the monitoringSlotPeriodicityAndOffset in the Search space as an example, a new time slot offset information offset value in the monitoringSlotPeriodicityAndOffset in the Search space can be predefined, and the communication device can determine the position of the first slot of the first periodic signal based on the predefined new time slot offset information offset value.

[0148] Optionally, only the period configuration information may be predefined, only the time slot offset information may be predefined, or both the period configuration information and the time slot offset information may be predefined. This embodiment does not limit this, and the same applies to other combinations of the second configuration information.

[0149] Taking the second configuration information including period configuration information and time slot offset information as an example, Figure 4 It is one of the schematic diagrams of the signal configuration method provided by the embodiment of the present application; the embodiment of the present application can determine the period and initial slot of PDCCH monitoring by modifying the definition of monitoringSlotPeriodicityAndOffset, and then confirm the position of subsequent slot(s) according to the definition of Duration already in the system, and confirm the position of PDCCH monitoring symbol in each slot through monitoringSymbolsWithinSlot. For example, the definition of monitoringSlotPeriodicityAndOffset can be modified, that is, the period and offset information carried by monitoringSlotPeriodicityAndOffset are all multiplied by a fixed value according to certain rules. The remaining parameters, such as monitoringSymbolsWithinSlot and Duration remain unchanged.

[0150] like Figure 4 As shown, assume that the configuration of CORESET is as follows:

[0151] frequencyDomainResources=00011111111111——(3 0s, 12 1s): represents that the position of CORESET is offset by 3 PRBs relative to PRB0, and there are 12 consecutive PRBs.

[0152] Duration = 2: indicates that this CORESET occupies 2 consecutive OFDM symbols.

[0153] Assume that the Search space is configured as follows:

[0154] monitoringSlotPeriodicityAndOffset=sl4.2: indicates that the period of the Search space is 4 slots and the offset is 2 slots.

[0155] monitoringSymbolsWithinSlot=00100000100000: represents that in each slot, there are two Occasions starting from the 3rd symbol and the 9th symbol respectively.

[0156] Duration = 2 means that the search space has two consecutive slots and each slot exists.

[0157] like Figure 4 As shown, when SCS = 480K, the period and offset information carried by monitoringSlotPeriodicityAndOffset can be multiplied by 4; when SCS = 960K, the period and offset information carried by monitoringSlotPeriodicityAndOffset can be multiplied by 8; then the position of the initial slot is obtained, and the position of the initial slot can be in any one of the slot groups, such as Figure 4 Slot 9, 10, 11, and 12 are a slot group, and the initial slot can be any one of them.

[0158] Then, the location of the subsequent slot(s) can be confirmed based on the existing Duration definition, and the location of the PDCCH monitoring symbol in each slot can be confirmed through monitoringSymbolsWithinSlot. Figure 4 As shown, Duration = 2, which means it lasts for two slots. monitoringSymbolsWithinSlot = 00100000100000: It means that in each slot, there are two Occasions starting from the 3rd symbol and the 9th symbol respectively.

[0159] Optionally, when the second configuration information includes symbol position configuration information, determining the second configuration information based on the subcarrier spacing SCS includes:

[0160] Based on the value corresponding to the original symbol position configuration information of the first periodic signal, after adding M zeros after each symbol, determine the value of the symbol position configuration information;

[0161] Herein, M is a first fixed value, which is determined based on the subcarrier spacing SCS.

[0162] Optionally, when the second configuration information includes symbol position configuration information, the value of the symbol position configuration information can be determined based on the value corresponding to the original symbol position configuration 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.

[0163] Optionally, when the second configuration information includes periodic configuration information, the communication device may update the symbol position configuration information based on the subcarrier spacing SCS, or may predefine the symbol position configuration information based on the subcarrier spacing SCS, and the communication device uses the predefined symbol position configuration information when configuring the first periodic signal.

[0164] Optionally, determining the first fixed value based on the subcarrier spacing SCS includes:

[0165] Based on the subcarrier spacing SCS, obtaining the first fixed value; or

[0166] The first fixed value is predefined based on the subcarrier spacing SCS.

[0167] Optionally, since the update or predefinition of the symbol position configuration information is based on the update or predefinition of the first fixed value, when the second configuration information includes the symbol position configuration information, the communication device can update the first fixed value M based on the subcarrier spacing SCS, or, can predefine the first fixed value M based on the subcarrier spacing SCS, and the communication device uses the predefined M to determine the symbol position configuration information when configuring the first periodic signal.

[0168] Optionally, determining the first fixed value based on the subcarrier spacing SCS includes:

[0169] Based on the subcarrier spacing SCS, determining a first fixed value corresponding to the SCS; or

[0170] Based on the subcarrier spacing SCS, a second mathematical relationship between the SCS and a preset target reference SCS is determined, and based on the second mathematical relationship, the first fixed value is calculated and obtained.

[0171] Optionally, when the first fixed value is updated based on the subcarrier spacing SCS and then the symbol position configuration information is updated, or the first fixed value is predefined based on the subcarrier spacing SCS, the first fixed value corresponding to the SCS can be determined based on the subcarrier spacing SCS, and then the symbol position configuration information can be determined.

[0172] For example, when the first fixed value is updated based on the subcarrier spacing SCS and then the symbol position configuration information is updated, or the first fixed value is predefined based on the subcarrier spacing SCS, the first fixed value corresponding to the SCS can be determined to be 3 based on the subcarrier spacing SCS=480kHz. The first fixed value corresponding to the SCS can be determined to be 7 based on the subcarrier spacing SCS=960kHz.

[0173] Optionally, 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 can be determined based on the subcarrier spacing SCS, and based on the second mathematical relationship, the first fixed value can be calculated to obtain the symbol position configuration information.

[0174] Optionally, the calculation rule in this embodiment may be predefined, that is, may be preconfigured or predefined by a protocol.

[0175] Optionally, the determining, based on the subcarrier spacing SCS, a second mathematical relationship between the SCS and a preset target reference SCS, and calculating and obtaining the first fixed value based on the second mathematical relationship includes:

[0176] Based on the subcarrier spacing SCS, determine that the quotient between the SCS and a preset second reference SCS is R, where R is a positive integer;

[0177] Subtract one from R to obtain the first fixed value.

[0178] Optionally, when the first fixed value is updated based on the subcarrier spacing SCS and thus the symbol position configuration information is updated, or when the first fixed value is predefined based on the subcarrier spacing SCS, the quotient between the SCS and a preset second reference SCS can be determined to be R based on the subcarrier spacing SCS, and R can be subtracted by one to obtain the first fixed value, and then the symbol position configuration information can be obtained.

[0179] For example, when the first fixed value is updated based on the subcarrier spacing SCS and then the symbol position configuration information is updated, or the first fixed value is predefined based on the subcarrier spacing SCS, taking the second reference SCS=120KHz as an example, if the subcarrier spacing BWP SCS=480kHz, 480 / 120-1=3, it can be determined that the first fixed value is 3, and then the symbol position configuration information is determined; if the subcarrier spacing BWP SCS=960kHz, 960 / 120-1=7, it can be determined that the first fixed value is 7, and then the symbol position configuration information is determined.

[0180] Taking the second configuration information including symbol position configuration information as an example, Figure 5This is the second schematic diagram of the signal configuration method provided by 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 through the definition of monitoringSlotPeriodicityAndOffset, and monitoringSlotPeriodicityAndOffset can be predefined or updated based on SCS or directly predefined or unchanged; the embodiment of the present application can directly confirm the monitoring symbol(s) in each PDCCH monitoring slot by modifying the definition of monitoringSymbolsWithinSlot.

[0181] like Figure 5 As shown, assume that the configuration of CORESET is as follows:

[0182] frequencyDomainResources=00011111111111——(3 0s, 12 1s): represents that the position of CORESET is offset by 3 PRBs relative to PRB0, and there are 12 consecutive PRBs.

[0183] Duration = 2: indicates that this CORESET occupies 2 consecutive OFDM symbols.

[0184] Assume that the Search space is configured as follows:

[0185] monitoringSlotPeriodicityAndOffset=sl4.2: indicates that the period of the Search space is 4 slots and the offset is 2 slots.

[0186] monitoringSymbolsWithinSlot=00100000100000: represents that in each slot, there are two Occasions starting from the 3rd symbol and the 9th symbol respectively.

[0187] Duration = 2 means that the search space has two consecutive slots and each slot exists.

[0188] like Figure 5 As shown, slots 9, 10, 11, and 12 of SCS480 correspond to slot 3 of SCS120; slots 13, 14, 15, and 16 of SCS480 correspond to slot 4 of SCS120.

[0189] The following two solutions are applicable to the embodiments of the present application:

[0190] a) Only the solution defined in monitoringSymbolsWithinSlot is modified; that is, the second configuration information only includes symbol position configuration information.

[0191] Directly modify the definition of monitoringSymbolsWithinSlot. For example, if monitoringSymbolsWithinSlot=00100000100000 is configured in the existing protocol, a fixed value of 0 is added after each symbol in monitoringSymbolsWithinSlot by default. In this case, the definition of monitoringSymbolsWithinSlot is at the symbol level.

[0192] Taking BWP SCS=480kHz, monitoringSymbolsWithinSlot=00100000100000 as an example, add 3 zeros after each symbol in each monitoringSymbolsWithinSlot; then monitoringSymbolsWithinSlot=0000000010000000000000000000000000100000000000000000000000000, and the search space to be monitored is at the symbol corresponding to the value of 1. Then an offset value can be added on this basis.

[0193] b) The second configuration information includes symbol position configuration information and duration information.

[0194] Optionally, the first fixed value may be predefined by the protocol, such as when the default SCS=480K, 3 zeros are added; when SCS=960K, 7 zeros are added; or a benchmark SCS is set, such as SCS=120K, the SCS of BWP is divided by the benchmark SCS, and the resulting value minus 1 is used as the number of zeros required to be added.

[0195] It should be noted that the offset value can be based on the slot or the symbol number. In the above example, the offset value is 0.

[0196] It should be noted that the two solutions listed above are only examples of the embodiments of the present application and are not intended to limit the embodiments of the present application.

[0197] Optionally, when the second configuration information includes symbol position configuration information, predefining the second configuration information includes:

[0198] Based on the value corresponding to the original symbol position configuration information of the first periodic signal, after adding N zeros after each symbol, determine the value of the symbol position configuration information;

[0199] Wherein, N is a second fixed value, and the second fixed value is predefined.

[0200] Optionally, the second fixed value N may be directly predefined, and then based on the value corresponding to the original symbol position configuration information of the first periodic signal, after adding N zeros after each symbol, the value of the symbol position configuration information is determined.

[0201] Optionally, when the second configuration information includes duration information, determining the second configuration information based on the subcarrier spacing SCS includes:

[0202] Determining a time slot spacing between time slots based on a subcarrier spacing SCS;

[0203] determining the duration information based on the time interval between the time slots and the time slot interval;

[0204] The time interval between the time slots is determined based on original duration information of the first periodic signal.

[0205] Optionally, when the second configuration information includes duration information, the time slot interval between time slots can be determined based on the subcarrier spacing SCS, and then the duration information can be determined in combination with the time interval between the time slots to configure the first periodic signal.

[0206] Taking the duration information as Duration in the Search space as an example, the time interval between the time slots can be determined based on the original duration information of the first periodic signal. For example, it can be determined that the first periodic signal was originally on 2 consecutive slots with a duration of 2ms. Then, on the basis of keeping the duration of 2ms unchanged, the duration information M can be determined based on the updated or predefined time slot interval (it can be understood that the search space to be monitored appears in M ​​slots, and the interval between each two search spaces is a determined time slot interval), so as to determine the positions of other slot(s) of the first periodic signal.

[0207] Optionally, determining the time slot interval between time slots based on the subcarrier spacing SCS includes:

[0208] Based on the subcarrier spacing SCS, obtaining the time slot spacing; or

[0209] The time slot interval is predefined based on the subcarrier spacing SCS.

[0210] Optionally, since the update or predefinition of the duration information is based on the update or predefinition of the time slot interval, when the second configuration information includes the duration information, the communication device can update the time slot interval based on the subcarrier interval SCS, or, can predefine the time slot interval based on the subcarrier interval SCS, and the communication device uses the predefined time slot interval to determine the duration information when configuring the first periodic signal.

[0211] Optionally, determining the time slot interval between time slots based on the subcarrier spacing SCS includes:

[0212] Based on the subcarrier spacing SCS, determining the time slot spacing corresponding to the SCS; or

[0213] Based on the subcarrier spacing SCS, a third mathematical relationship between the SCS and a preset target reference SCS is determined, and based on the third mathematical relationship, the time slot spacing is calculated and obtained.

[0214] Optionally, when the time slot interval is updated based on the subcarrier spacing SCS and then the duration information is updated, or when the time slot interval is predefined based on the subcarrier spacing SCS, the duration information corresponding to the SCS can be determined based on the subcarrier spacing SCS and then the duration information is determined.

[0215] For example, when the time slot interval is updated based on the subcarrier spacing SCS and then the duration information is updated, or the time slot interval is predefined based on the subcarrier spacing SCS, the time slot interval corresponding to the SCS can be determined to be 4 based on the subcarrier spacing SCS=480kHz. The time slot interval corresponding to the SCS can be determined to be 8 based on the subcarrier spacing SCS=960kHz.

[0216] Optionally, when updating the time slot interval based on the subcarrier spacing SCS and thus updating the duration information, or predefining the time slot interval based on the subcarrier spacing SCS, a third mathematical relationship between the SCS and a preset target reference SCS can be determined based on the subcarrier spacing SCS, and based on the third mathematical relationship, the time slot interval can be calculated to obtain the duration information.

[0217] Optionally, the calculation rule in this embodiment may be predefined, that is, may be preconfigured or predefined by a protocol.

[0218] Optionally, determining a third mathematical relationship between the SCS and a preset target reference SCS based on the subcarrier spacing SCS, and calculating and obtaining the time slot interval based on the third mathematical relationship includes:

[0219] Based on the subcarrier spacing SCS, determine that the quotient between the SCS and a preset third reference SCS is L, where L is a positive integer;

[0220] The time slot interval is determined to be L.

[0221] Optionally, when the time slot interval is updated based on the subcarrier spacing SCS and thus the duration information is updated, or when the time slot interval is predefined based on the subcarrier spacing SCS, the quotient between the SCS and a preset second reference SCS can be determined to be L based on the subcarrier spacing SCS, and the time slot interval can be determined to be L, thereby obtaining the duration information.

[0222] For example, when the time slot interval is updated based on the subcarrier spacing SCS and then the duration information is updated, or when the time slot interval is predefined based on the subcarrier spacing SCS, taking the third reference SCS=120KHz as an example, if the subcarrier spacing BWP SCS=480kHz, 480 / 120=4, it can be determined that the time slot interval is 4, and then the duration information is determined; if the subcarrier spacing BWP SCS=960kHz, 960 / 120=8, it can be determined that the time slot interval is 8, and then the duration information is determined.

[0223] Taking the second configuration information including duration information as an example, Figure 6 This is the third schematic diagram of the signal configuration method provided in the 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 through the definition of monitoringSlotPeriodicityAndOffset, and monitoringSlotPeriodicityAndOffset can be predefined or updated based on SCS or directly predefined or unchanged; the embodiment of the present application can confirm the position of subsequent slot(s) after modifying the definition of Duration, and confirm the position of PDCCH monitoring symbol in each slot through monitoringSymbolsWithinSlot.

[0224] like Figure 6 As shown, assume that the configuration of CORESET is as follows:

[0225] frequencyDomainResources=000111111 1111——(3 zeros, 12 ones): represents that the position of CORESET relative to PRB0 is offset by 3 PRBs, and there are 12 consecutive PRBs.

[0226] Duration = 2: indicates that this CORESET occupies 2 consecutive OFDM symbols.

[0227] Assume that the Search space is configured as follows:

[0228] monitoringSlotPeriodicityAndOffset=sl4.2: indicates that the period of the Search space is 4 slots and the offset is 2 slots.

[0229] monitoringSymbolsWithinSlot=00100000100000: represents that in each slot, there are two Occasions starting from the 3rd symbol and the 9th symbol respectively.

[0230] Duration = 2 means that the search space has two consecutive slots and each slot exists.

[0231] like Figure 6 As shown, slots 9, 10, 11, 12 of SCS = 480kHz correspond to slot 3 of SCS 120; slots 13, 14, 15, 16 of SCS = 480kHz correspond to slot 4 of SCS = 120kHz.

[0232] The following two solutions are applicable to this embodiment:

[0233] Solution c): Only the solution defined by Duration is modified; that is, the second configuration information only includes duration information.

[0234] Optionally, the definition of duration can be modified directly, for example, duration = M can be configured, then the search space to be monitored appears in M ​​slots by default, and each slot is separated by a second fixed value of slots. That is, after the definition of duration is modified, the second fixed value of slots may appear between the search spaces that originally appeared consecutively in slot 3 and slot 4, so the positions of these two search spaces are changed to slot 9 and slot 13, but the time interval between the two search spaces remains unchanged.

[0235] Solution d): The second configuration information includes duration information, period configuration information and time slot offset information.

[0236] Optionally, the updated or predefined content of monitoringSlotPeriodicityAndOffset may be combined to confirm multiple time domain positions of the search space. Figure 6As shown, the period configuration in monitoringSlotPeriodicityAndOffset can be updated or predefined, and then the offset in monitoringSlotPeriodicityAndOffset and the value in the Duration indication field are combined to jointly confirm multiple time domain positions of the search space, that is, (offset+duration{0,1…n})*fixed value+offset value.

[0237] As described in schemes c) and d), the time slot interval can be called the second fixed value and can be predefined by the protocol, such as multiplying by 4 when the default SCS=480kHz; multiplying by 8 when SCS=960K. Alternatively, a reference SCS is set, such as SCS=120kHz, and the SCS of the BWP is divided by the reference SCS, and the resulting value is used as the value to be multiplied.

[0238] It should be noted that the two solutions listed above are only examples of the embodiments of the present application and are not intended to limit the embodiments of the present application.

[0239] It should be noted that the offset value can be based on the slot or the symbol number.

[0240] Optionally, the offset value is 0.

[0241] Optionally, when the second configuration information includes duration information, predefining the second configuration information includes:

[0242] a time slot interval between predefined time slots;

[0248] Optionally, the period of the first periodic signal can be directly obtained according to the value of the period configuration information, or obtained after being updated.

[0249] Taking the period configuration information as monitoringSlotPeriodicityAndOffset in the Search space as an example, the period of the first periodic signal can be directly obtained according to the value of the period in monitoringSlotPeriodicityAndOffset, or obtained after updating.

[0250] Optionally, when the second configuration information includes time slot offset information, configuring the first periodic signal based on the first configuration information includes:

[0251] Based on the time slot offset information in the second configuration information, a position of a target time slot of the first periodic signal is determined.

[0252] Optionally, after determining the period of the first periodic signal, the position of a target slot, such as the first slot, in each period may be determined.

[0253] Optionally, the target time slot may be a predefined time slot, for example, it may be the first time slot of the first periodic signal, or it may be the last time slot.

[0254] Optionally, the position of the target time slot of the first periodic signal can be directly obtained according to the time slot offset information, or obtained after updating.

[0255] Taking the offset in monitoringSlotPeriodicityAndOffset in the Search space as an example, the position of the target time slot of the first periodic signal can be directly obtained according to the value of the offset in monitoringSlotPeriodicityAndOffset, or obtained after updating.

[0256] Optionally, when the second configuration information includes duration information, configuring the first periodic signal based on the first configuration information includes:

[0257] Based on the duration information in the second configuration information, the time interval between the time slots of the first periodic signal is determined, and based on the time interval, the positions of other time slots are determined, and the other time slots include: time slots other than the target time slot.

[0258] Optionally, after determining the position of the target slot in each cycle, such as the position of the first slot, the positions of other slot(s) may be determined.

[0259] Optionally, the target time slot may be a predefined time slot, for example, may be the first time slot of the first periodic signal, and the other time slots may be subsequent slot(s) of the first periodic signal.

[0260] Optionally, the time interval between time slots of the first periodic signal may be determined based on the duration information in the second configuration information, and then the time interval may be divided by the duration of each slot to obtain the positions of other slots relative to the first slot.
