Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a method for transmitting system information, a communication device, and related equipment. Background Art

[0002] For high-frequency bands, signal transmission is based on beamforming. Beamforming is a technology that limits the energy of the transmitted signal to a certain beam direction to increase signal transmission efficiency. In order to achieve full coverage, network equipment will perform beam scanning. The New Radio (NR) protocol stipulates that the synchronization signal / physical broadcast channel block (SS / PBCH block) repeats within a period. Some types of physical downlink control channels (PDCCH) (such as Type0-PDCCH) and the corresponding SS / PBCH block use the same beam to send. In some scenarios, Type0-PDCCH is arranged in time division, and different beams occupy different time slots. However, continuous Type0-PDCCH signal transmission will result in the inability to transmit other signals for a long period of time. In the future, as the number of beams supported by network equipment increases, how to balance the transmission of Type0-PDCCH signals and other signals becomes an urgent problem to be solved. Summary of the Invention

[0003] The present application provides a system information transmission method, communication device and related equipment, which can provide Type0PDCCH transmission for each beam of a network device and ensure the transmission of other signals, thereby improving communication efficiency.

[0004] In the first aspect, the present application provides a system information transmission method, which can be executed by a network device, specifically including: the network device sends at least two first signals to the terminal device based on a first period, and one first signal corresponds to a beam of the network device; wherein, the first period includes a first time slot and a second time slot, the first time slot is used to transmit the first signal, and the second time slot is used to transmit other signals except the first signal, and at least one second time slot is located between two first time slots.

[0005] In the second aspect, the present application provides another system information transmission method, which can be executed by a terminal device, specifically including the terminal device monitoring a first signal based on a first period, and one first signal corresponds to a beam of a network device; wherein the first period includes a first time slot and a second time slot, the first time slot is used to transmit the first signal, and the second time slot is used to transmit other signals except the first signal, and at least one second time slot is located between two first time slots; according to the monitoring results, the terminal device receives the first signal.

[0006] In one possible design, the first signal is a Type0-PDCCH signal, and the other signals are uplink signals or downlink signals other than Type0-PDCCH, where the uplink signal refers to an uplink signal of terminal devices other than the terminal device receiving the Type0-PDCCH signal, and the downlink signal can be a downlink signal sent to the terminal device receiving the Type0-PDCCH signal, or a downlink signal sent to terminal devices other than the terminal device receiving the Type0-PDCCH signal.

[0007] In high-frequency scenarios, such as the 52.6 GHz and above frequency bands, in order to ensure cell coverage performance, there are certain requirements for the number of beams and the Type0-PDCCH signals corresponding to the beams. The above-mentioned design of a period including the first time slot and the second time slot can support the transmission of Type0-PDCCH signals while ensuring cell coverage performance, and avoid the long-term inability to transmit other signals, such as the uplink signals of other terminal devices in the cell, thereby improving communication performance.

[0008] In one possible design, in order to achieve more flexible configuration, the first time slot in the first cycle is divided into at least two first time slot groups, one first time slot group includes at least two first time slots, and at least one second time slot is located between the at least two first time slot groups.

[0009] Optionally, different first time slot groups include different numbers of first time slots. Thus, the transmission modes of the first signal and other signals can be designed for different scenarios, thereby increasing the flexibility of signal transmission and improving the communication performance of the system.

[0010] In one possible design, the first cycle includes g first time slot groups, where the configuration of the g first time slot groups is {N1, N2, ..., N j}, where j = 1, 2 ... g, the N j is the number of first time slots included in the jth first time slot group, g≥2, N j ≥1, the g and N j is an integer.

[0011] Optionally, g second time slot groups {K1, K2, ...K j}, K j is the number of second time slots included in the jth second time slot group, K j ≥1 and is an integer. The jth second time slot group is located after the jth first time slot group.

[0012] Optionally, the configuration of the first time slot and the second time slot in the first cycle can also be {N1, K1, N2, K2, ... N j , K j}.

[0013] Using time slot group configuration can adapt to time domain resource allocations with different uplink and downlink time slot ratios. This means that when the uplink and downlink time slot ratios in the first cycle are different, the configurations of the g first time slot groups or the g second time slot groups are the same. This eliminates the need to design separate first and second time slot distributions for different uplink and downlink time slot ratios, saving signaling overhead and improving communication efficiency.

[0014] In one possible design, the first cycle includes two first time slot groups, and the configuration of the two first time slot groups is {N1, N2}, where the value of N1 or N2 is any one of the set {2, 3, 4, 6, 7, 8, 10, 12, 14, 16, 24, 32}.

[0015] In one possible design, the first cycle includes two second time slot groups, and the configuration of the two second time slot groups is {K1, K2}, and the value of K1 or K2 is any one of the set {1, 2, 3, 4, 6, 7, 8, 10, 16, 20}.

[0016] In one possible design, the first cycle includes four first time slot groups, and the configuration of the four first time slot groups is {N1, N2, N3, N4}, where the values ​​of N1, N2, N3 or N4 are any one of the set {1, 2, 3, 4, 6, 7, 8, 9, 14, 16, 18}.

[0017] In one possible design, the first cycle includes four second time slot groups, and the configuration of the two second time slot groups is {K1, K2, K3, K4}, and the value of K1, K2, K3 or K4 is any one in the set {}.

[0018] In one possible design, sending at least two first signals to the terminal device based on the first period includes:

[0019] At least two first signals are sent to the terminal device based on at least two beams, and the starting time slot n of the first signal of the i-th beam satisfies: n = (O + floor (i * M) + floor (floor (i * M) / N) * K, O represents the starting time slot for the first beam to send the Type0-PDCCH signal, M represents the number of Type0-PDCCH signals sent in 1 time slot, N represents the number of time slots included in 1 first cycle, K represents the number of second time slots included in 1 first cycle, O = 0 or 5, M = 1, 2 or 1 / 2, i ≥ 1.

[0020] In one possible design of the second aspect, monitoring the first signal based on the first period includes:

[0021] Based on the first cycle monitoring of the first signal, the starting time slot n of the first signal corresponding to the i-th beam satisfies: n = (O + floor (i * M) + floor (floor (i * M) / N) * K, O represents the starting time slot of the first beam of the network device sending the first signal, M represents the number of times the first signal is monitored within 1 time slot, N represents the number of time slots included in 1 first cycle, K represents the number of second time slots included in 1 first cycle, O = 0 or 5, M = 1, 2 or 1 / 2, i ≥ 1.

[0064] In addition, various aspects or features of the present application can be implemented as methods, devices or products using standard programming and / or engineering techniques.

[0065] To facilitate understanding of the relevant contents of the embodiments of the present application, some concepts involved in the embodiments of the present application are exemplarily explained.

[0066] Quasi co-location relationship: Quasi co-location (QCL) relationship, the association in this application can also be called mapping, corresponding, and related. When there is QCL between two signals, that is, the same delay spread, the same Doppler spread, the same average gain, the same average delay, the same spatial parameters can be used to send or receive signals, and at least one of the same beam can be used to send or receive signals. The parameters of quasi co-location include: Doppler spread, Doppler frequency shift, average delay, delay spread and at least one of spatial reception parameters. QCL relationships can be divided into four categories: 'QCL-TypeA': {Doppler frequency shift, Doppler spread, average delay, delay spread}; 'QCL-TypeB': {Doppler frequency shift, Doppler spread}; 'QCL-TypeC': {Doppler frequency shift, average delay}; 'QCL-TypeD': {spatial reception parameters}. When selecting QCL relationship parameters, you can select them arbitrarily, for example, select average gain and 'QCL-TypeD'.

[0067] Beam: In the NR protocol, a beam can be represented by a spatial domain filter, also known as a spatial filter or spatial parameter. The beam used to transmit signals can be called a transmission beam (Tx beam), a spatial domain transmission filter, or a spatial transmission parameter. The beam used to receive signals can be called a reception beam (Rx beam), a spatial domain receive filter, or a spatial RX parameter.

[0068] The transmit beam may refer to the distribution of signal strength in different directions in space after the signal is transmitted by the antenna, and the receive beam may refer to the distribution of signal strength in different directions in space of the wireless signal received from the antenna.

[0069] Furthermore, the beam can be a wide beam, a narrow beam, or other types of beams. The beam forming technology can be beamforming technology or other technologies. The beamforming technology can specifically be digital beamforming technology, analog beamforming technology, or hybrid digital / analog beamforming technology.

[0070] Beams generally correspond to resources or signals. For example, when performing beam measurement, network equipment uses different resources to measure different beams. The terminal device then feeds back the measured resource quality, allowing the network equipment to determine the quality of the corresponding beam. During data transmission, beam information is also indicated by its corresponding resources. For example, the network equipment uses the resources in the transmission configuration indicator (TCI) of the downlink control information (DCI) to indicate the physical downlink shared channel (PDSCH) beam information to the terminal device.

[0071] Optionally, multiple beams with the same or similar communication characteristics can be considered a single beam. A beam can include one or more antenna ports for transmitting data channels, control channels, and sounding signals. The one or more antenna ports forming a beam can also be considered an antenna port set.

[0072] In the embodiments of the present application, if not specified, a beam refers to a transmitting beam of a network device. In beam measurement, each beam of the network device corresponds to a resource, and therefore the beam corresponding to the resource can be uniquely identified by the index of the resource.

[0073] A beam can be represented by a QCL relationship in a standard.

[0074] System information block: a system information block (SIB) contains system information blocks (SIBs) in a cell, and the information carried by the system information blocks is different, for example, SIB1 mainly carries some configuration information of the cell itself, such as random access related information, physical downlink control channel (PDCCH) related information, other information block related information, UE access cell information, cell identification information and the like.

[0075] Synchronization signal block: a synchronization signal block (SSB) can also be referred to as an SS (Synchronization Signal) / PBCH (Physical broadcast channel) block, and the SS / PBCH block contains at least one of a primary synchronization signal (PSS), a secondary synchronization signal (SSS), a physical broadcast channel (PBCH) and a demodulation reference signal (DMRS). The SS / PBCH block can also be referred to as an SSB / PBCH block, and the signals in the SS / PBCH block or the SSB / PBCH block can be the same antenna port.

[0076] Please refer to Figure 2, illustrating the signaling interaction process for the terminal device to access the cell. The terminal device first blindly detects the SSB. After blindly detecting the SSB, it will receive the main information block (MIB) information carried in the SSB. The MIB signal contains the configuration information of the control resource set (CORESET) and common search space (CSS) of SIB1, as well as other indications, such as subcarrier spacing. The terminal device receives the CORESET of SIB1 according to the indication, and the CORESET of SIB1 contains the PDCCH of SIB1. Exemplarily, the PDCCH of SIB1 can also be called "Type0-PDCCH", and the PDCCH signal of SIB1 is called "Type0-PDCCH signal". It can be understood that "Type0-PDCCH signal" is not used to limit the signal itself, and other names may be used in other implementations. The PDCCH of SIB1 indicates the PDSCH position of SIB1 and related information such as the modulation and coding strategy. The terminal device receives the PDSCH according to the indication of the PDCCH. In NR, the PDCCH of SIB1 and the physical downlink shared channel (PDSCH) of SIB1 have the same subcarrier spacing. The specific information of SIB1 is transmitted in the PDSCH, and the PDCCH of SIB1 indicates the time-frequency resource location of the PDSCH and other relevant information of the PDSCH, such as modulation and coding information. For frequency bands above 52.6GHz, the transmission of information is based on beamforming. Therefore, the transmission of PDCCH and PDSCH of SIB1 is also based on beams. Since the first signal received by the terminal device is SSB, and the SSB of the base station corresponds to each beam, the beam of SSB can be considered as a reference standard, and the relevant information of SIB1 is also associated with the beam of SSB, that is, the beam of SIB1 is the same as the beam of SSB, and the two types of information are sent using the same beam.

[0077] The following describes the system information transmission method and related devices described in the embodiments of the present application in conjunction with the accompanying drawings, wherein, based on a specially designed transmission period, the network device sends Type0-PDCCH to the terminal device through multiple beams. Figure 4 , Figure 4 This is a flow chart of a method for transmitting control information provided by an embodiment of the present application. Figure 4 As shown, the system information transmission method includes the following steps:

[0078] 101: The network device determines at least one first period for transmitting a first signal. Each first signal corresponds to a beam of the network device. In other words, the first period is the period for transmitting the first signal. Within each first period, multiple beams of the network device transmit their corresponding first signals.

[0079] It can be understood that 101 is an optional step, and the network device can determine the at least one first period according to system parameters or according to a protocol.

[0080] 102: The network device sends a first signal to the terminal device based on the first cycle, where the first cycle includes a first time slot and a second time slot, the first time slot is used to transmit the first signal, the second time slot is used to transmit signals other than the first signal, and at least one second time slot is located between two first time slots;

[0081] Exemplarily, the first signal may be a Type0-PDCCH signal. The first time slot is used to send a Type0-PDCCH signal and may be referred to as a "Type0-PDCCH time slot". The second time slot is used to send other signals except Type0-PDCCH, and the other signal may be an uplink signal or a downlink signal. Among them, a first time slot is used for a beam of a network device to send its own Type0-PDCCH signal, that is, a beam of a network device sends its own Type0-PDCCH signal in a first time slot. Accordingly, the terminal device receives the Type0-PDCCH signal based on the first time slot. A second time slot is used to send other signals. Taking the second time slot as an uplink signal as an example, the terminal device sends an uplink signal in the second time slot, and accordingly, the network device receives an uplink signal from the terminal device in the second time slot.

[0082] Optionally, the network device may send the configuration of the first cycle to the terminal device. For example, if there are multiple possible configuration methods for the first cycle, the network device may send the configuration index to the terminal device, such as the index in Table 5 or Table 8 below; or, the network device may send the configuration of the first cycle itself to the terminal device.

[0083] 103: The terminal device communicates with the network device based on the first period. Specifically, the terminal device monitors the first signal and receives the first signal.

[0084] According to the first period, the terminal device monitors the first signal on the corresponding time domain resource, and after successful monitoring, the terminal device receives the Type0-PDCCH signal from the network device on the time domain resource corresponding to the first time slot, and on the time domain resource corresponding to the second time slot, the terminal device can send a signal to the network device, or the terminal device can receive other signals from the network device except Type0-PDCCH.

[0085] The above system information transmission method can ensure that other signals can be transmitted in time, especially in the scenario above 52.6GHz, and the network device has more beams to transmit, which improves the performance of the communication system.

[0086] Next, the beams of the network device are further described. The beams of the network device have an index, which can be represented by the index of the synchronization signal block (SSB). That is, the index of the beam of the network device can be the same as the index of the corresponding SSB. The beams of the network device can be divided into multiple beam groups, and each beam group includes more than or equal to one beam. The Type0-PDCCH signal corresponding to the beam of the network device can be divided into multiple Type0-PDCCH groups, and each Type0-PDCCH group includes the Type0-PDCCH signal corresponding to one beam group. That is, one beam group includes N beams, and the corresponding Type0-PDCCH group can include N Type0-PDCCH signals. In terms of technical essence, the beam group and the Type0-PDCCH group are equivalent.

[0087] The number of Type0-PDCCH signals transmitted by the network device is related to the number of beams supported by the network device. According to different scenarios, the number of beams can be different. Optionally, the number of beams can be greater than 4, for example, it can be 32, 64 or 128. Accordingly, the network device transmits 32, 64 or 128 Type0-PDCCH signals.

[0088] Next, the above first period is described exemplarily.

[0089] The first period is a transmission period of the Type0-PDCCH signal. In one first period, multiple beams of the network device respectively transmit the Type0-PDCCH signal, one beam corresponds to one Type0-PDCCH, in other words, the network device transmits one Type0-PDCCH signal through one beam. Thus, in one transmission period, the transmission of the Type0-PDCCH of multiple beams of the network device can be completed. It can be understood that if there are multiple first periods, the multiple beams of the network device can repeatedly transmit the Type0-PDCCH signal in different first periods. Alternatively, in some embodiments, based on the number of beams, the network device can transmit the Type0-PDCCH signal based on multiple first periods, which can be included in one or more second periods.

[0090] The first period can include one or more time units, and in different embodiments, the number of time units included in the second period can be different. For example, the time unit can be a slot, and depending on different system parameter configurations, the number of slots included in one first period can be different. For example, the first period can be one radio frame, and one radio frame can include 40 slots. The second period can include 2 first periods, i.e., two radio frames, and thus one second period includes 80 slots.

[0091] One first period includes at least one first slot and at least one second slot. One first period can correspond to one Type0-PDCCH group, and the Type0-PDCCH signal in one Type0-PDCCH group is transmitted in at least one first slot in the corresponding first period. The at least one first slot in the first period for transmitting the Type0-PDCCH signal can be referred to as a "Type0-PDCCH slot group". In some embodiments, one Type0-PDCCH signal can be transmitted in one first slot, that is, one beam can transmit the Type0-PDCCH signal in one first slot; in other embodiments, multiple Type0-PDCCH signals can be transmitted in one first slot, in other words, multiple beams can transmit the Type0-PDCCH signal in one first slot.

[0092] Under different numerologies, the first period can adopt different configuration modes, and more examples will be given below.

[0093] Please refer to Figure 4, a first period is exemplarily shown from a symbol level. As shown in the figure, 1 first period includes 10 time slots, i.e. T=10, wherein time slots 0-7 are designed as first time slots for transmitting Type0-PDCCH signals, and time slots 8 and 9 are designed as second time slots for transmitting other signals. Taking an example of transmitting 1 Type0-PDCCH signal in 1 time slot, the starting symbol of the Type0-PDCCH signal is symbol 0, the Type0-PDCCH signal occupies 3 symbols from symbol 0 to symbol 2, and other signals occupy 11 symbols from symbol 3 to symbol 13. In one example, the other signals can be PDSCH signals carrying SIB1. Figure 4 In the above, the Type0-PDCCH signal corresponding to 1 time slot corresponds to 1 beam, and 8 beams of the network device can transmit corresponding Type0-PDCCH signals in 1 first period. If the network device has 64 beams, 8 first periods are occupied for transmission.

[0094] In other embodiments, the second period and the first period are configured according to the number of beams supported by the network device. For example, as shown in Figure 5 , 2 Type0-PDCCH signal transmission opportunities can be designed in 1 time slot, and then 16 beams can transmit corresponding Type0-PDCCH signals in 1 first period. If the network device has 128 beams, 8 first periods are occupied for transmission. Optionally, the 8 first periods can be contained in 2 second periods.

[0095] In a high-frequency scenario, for example, a frequency band of 52.6 GHz and above, in order to guarantee the cell coverage performance, the number of beams and the Type0-PDCCH signals corresponding to the beams have certain requirements. By using the above design of the period containing the first time slot and the second time slot, the transmission of the Type0-PDCCH signal can be supported under the premise of guaranteeing the cell coverage performance, and long-time transmission of other signals, such as uplink signals of other terminal devices in the cell, can be avoided, thereby improving the communication performance.

[0096] The following further describes the first period. A first period may include T time slots, where T≥2. In different implementations, the value of T may be different. In other words, the number of time slots included in a first period may be different. The T time slots include K second time slots and N first time slots, where K≥1. The relationship between T, K, and N satisfies: N=TK. It should be noted that the configuration parameters of the first period may be predefined by the protocol, or the configuration parameters of the first period may be dynamically configured by signaling, such as carried on a physical broadcast channel (PBCH). In different implementations, the configuration parameters of the first period may be at least two of T, K, or N. For example, the configuration parameters of the first period may be T and K, the configuration parameters of the first period may be T and N, or the configuration parameters of the first period may be K or N. Exemplarily, the value of T may be any one of the set {4, 5, 6, 8, 10, 12, 16, 20, 32, 36, 40}.

[0097] In some implementations, the configuration parameters of the first cycle may be T and K. The values ​​of T and K may refer to the following Table 1:

[0098] Table 1

[0099]

[0100] Taking T=5 as an example, indicating that one first period includes 5 time slots, and taking the example of sending two Type0-PDCCH signals in one first time slot, if K=2, indicating that one first period includes 3 first time slots and 2 second time slots, the number of Type0-PDCCH signals sent in one first period is 6; if K=1, indicating that one first period includes 4 first time slots and 1 second time slot, the number of Type0-PDCCH signals sent in one first period is 8. Taking the example of sending one Type0-PDCCH signal in one first time slot, if K=2, indicating that one first period includes 3 first time slots and 2 second time slots, the number of Type0-PDCCH signals transmitted in one first period is 3; if K=1, indicating that one first period includes 4 first time slots and 1 second time slot, the number of Type0-PDCCH signals transmitted in one first period is 4. Taking the example of sending one Type0-PDCCH signal in two time slots, if K=2, it means that the first period includes three first time slots and two second time slots, and the number of Type0-PDCCH signals sent in the first period is 1. If K=1, it means that the first period includes four first time slots and one second time slot, and the number of Type0-PDCCHs sent in the first period is 2.

[0101] Taking T=10 as an example, indicating that one first period includes 10 time slots, and taking the example of sending two Type0-PDCCH signals in one first time slot, if K=4, indicating that one first period includes 6 first time slots and 4 second time slots, the number of Type0-PDCCH signals sent in one first period is 12. If K=2, indicating that one first period includes 8 first time slots and 2 second time slots, the number of Type0-PDCCH signals sent in one first period is 16. Taking the example of sending one Type0-PDCCH signal in one first time slot, if K=4, indicating that one first period includes 6 first time slots and 4 second time slots, the number of Type0-PDCCH signals sent in one first period is 6. If K=2, indicating that one first period includes 8 first time slots and 2 second time slots, the number of Type0-PDCCH signals sent in one first period is 8. Taking the example of sending one Type0-PDCCH in two first time slots, if K=4, it means that the first cycle includes 6 first time slots and 4 second time slots, then the number of Type0-PDCCH signals sent in the first cycle is 3. If K=2, it means that the first cycle includes 8 first time slots and 2 second time slots, then the number of Type0-PDCCH signals sent in the first cycle is 4.

[0102] For example, T = 20 indicates that one first period includes 20 time slots, and for example, 2 Type0-PDCCH signals are transmitted in one first time slot, if K = 8, it indicates that the one first period includes 12 first time slots and 8 second time slots, and the number of Type0-PDCCH signals transmitted in the one first period is 24; if K = 5, it indicates that the one first period includes 15 first time slots and 5 second time slots, and the number of Type0-PDCCH signals transmitted in the one first period is 30; if K = 4, it indicates that the one first period includes 16 first time slots and 4 second time slots, and the number of Type0-PDCCH signals transmitted in the one first period is 32; if K = 2, it indicates that the one first period includes 18 first time slots and 2 second time slots, and the number of Type0-PDCCH signals transmitted in the one first period is 36; if K = 1, it indicates that the one first period includes 19 first time slots and 1 second time slot, and the number of Type0-PDCCH signals transmitted in the one first period is 38. For example, 1 Type0-PDCCH signal is transmitted in one time slot, if K = 8, it indicates that the one first period includes 12 first time slots and 8 second time slots, and the number of Type0-PDCCH signals transmitted in the one first period is 12; if K = 5, it indicates that the one first period includes 15 first time slots and 5 second time slots, and the number of Type0-PDCCH signals transmitted in the one first period is 15; if K = 4, it indicates that the one first period includes 16 first time slots and 4 second time slots, and the number of Type0-PDCCH signals transmitted in the one first period is 16; if K = 2, it indicates that the one first period includes 18 first time slots and 2 second time slots, and the number of Type0-PDCCH signals transmitted in the one first period is 18; if K = 1, it indicates that the one first period includes 19 first time slots and 1 second time slot, and the number of Type0-PDCCH signals transmitted in the one first period is 19. For example, 1 Type0-PDCCH signal is transmitted in 2 time slots, if K = 8, it indicates that the one first period includes 12 first time slots and 8 second time slots, and the number of Type0-PDCCH signals transmitted in the one first period is 6; if K = 4, it indicates that the one first period includes 16 first time slots and 4 second time slots, and the number of Type0-PDCCH signals transmitted in the one first period is 8; if K = 2, it indicates that the one first period includes 18 first time slots and 2 second time slots, and the number of Type0-PDCCH signals transmitted in the one first period is 9.

[0103] In some embodiments, the configuration parameters of the first period can be T and N, and the values of T and N can be as shown in Table 1:

[0104] Table 2

[0105]

[0106] Next, the number of Type0-PDCCH signals sent by the network device in a first period is exemplified. Under different system parameters, the number of Type0-PDCCH signals sent by the network device in a first time slot is different. The network device sends P Type0-PDCCH signals in a first period, and the value of P satisfies: P = M × (TK), M represents the number of Type0-PDCCH signals sent by the network device in a first time slot, M ≥ 1, P ≥ 2. The value of M can be any one of {1 / 2, 1, 2}, where M = 1 / 2 means that 1 Type0-PDCCH signal is transmitted in 2 first time slots, M = 1 means that 1 Type0-PDCCH signal is transmitted in 1 first time slot, and M = 2 means that 2 Type0-PDCCH signals are transmitted in 1 first time slot. If the network device sends one Type0-PDCCH signal in one first time slot, P = TK; if the network device sends two Type0-PDCCH signals in one first time slot, P = 2×(TK); if the network device sends one Type0-PDCCH signal in two first time slots, P = 1 / 2×(TK).

[0107] Taking M=2 and the configuration parameters of the first cycle as T and K as an example, the number P of Type0-PDCCH signals sent by the network device in a first cycle is shown in the following Table 3:

[0108] Table 3

[0109] T K P 5 2 6 10 4 12 20 8 24 40 16 48 80 32 64

[0110] Taking T=5 and K=2 as an example, T=5 means that one first cycle includes 5 time slots, K=2 means that there are 2 second time slots in the one first cycle. Based on this, there are 3 first time slots in the one first cycle, and the first cycle network device can send 8 Type0-PDCCH signals in the one first cycle.

[0111] Taking T=10 and K=4 as an example, T=10 means that 1 first cycle includes 10 time slots, K=4 means that there are 4 second time slots in the 1 first cycle. Based on this, the 1 first cycle includes 6 second time slots, and the first cycle network device can send 16 Type0-PDCCH signals in the 1 first cycle.

[0112] For example, T=20 and K=8, T=20 indicates that one first period contains 20 slots, and K=8 indicates that the one first period contains 8 first slots, based on which the one first period contains 12 first slots, and thus the network device can send 32 Type0-PDCCH signals in the one first period.

[0113] For example, T=40 and K=16, T=40 indicates that one first period contains 40 slots, and K=16 indicates that the one first period contains 16 second slots, based on which the one first period contains 24 first slots, and thus the network device can send 48 Type0-PDCCH signals in the one first period.

[0114] For example, T=80 and K=32, T=80 indicates that one first period contains 80 slots, and K=32 indicates that the one first period contains 32 second slots, based on which the one first period contains 48 first slots, and N=96 indicates that the network device can send 96 Type0-PDCCH signals in the one first period.

[0115] In the foregoing embodiments, the network device can send Type0-PDCCH signals in one first period under different configurations of T, K, or N is exemplarily illustrated. Through the foregoing design, the network device can send Type0-PDCCH signals of more number of beams based on the first period, and can balance the timely sending of other downlink signals or uplink signals of other terminal devices, thereby improving the communication efficiency.

[0116] Optionally, in some embodiments, the network device can send Type0-PDCCH signals to the terminal device based on a second period, where the second period includes at least two first periods. In one second period, the number of first slots contained in different first periods can be the same or different, thereby achieving more flexible configuration. In one example, the second period can be 2 frames, and the first period can be 10 slots, and thus one second period can include 8 first periods. As shown in FIG. 4, the second period includes 4 first periods, each of which includes 10 slots and includes 8 first slots and 2 second slots. Figure 6 As shown in FIG. 5, the second period includes 4 first periods, each of which includes 10 slots, where two first periods include 8 first slots and 2 second slots, and the remaining two first periods include 6 first slots and 4 second slots. Figure 7 As shown in FIG. 5, the second period includes 4 first periods, each of which includes 10 slots, where two first periods include 8 first slots and 2 second slots, and the remaining two first periods include 6 first slots and 4 second slots.

[0117] In some embodiments, the uplink and downlink time slot ratio in a first period can be different due to different system parameter configurations. The following describes T, the uplink and downlink time slot ratio, and K for different system parameter configurations. Exemplarily, T, the uplink and downlink time slot ratio, and K satisfy Table 4. In Table 4, SCS refers to the subcarrier spacing of the subcarriers in the resource carrying the Type0-PDCCH signal, D represents a downlink time slot for transmitting a downlink signal, Unknown represents a flexible time slot, which can be designed as a first time slot or a second time slot, and U represents an uplink time slot for transmitting an uplink signal.

[0122] Taking SCS of 15 kHz, T = 10, D + Unknown: U = 6:4, and K = 4 or 5 as an example, a first period includes 10 time slots, and according to D + Unknown: U = 6:4, the number of uplink time slots is determined to be 4, and the total number of downlink time slots and flexible time slots is 6. If K = 4, it means that the first period includes 4 second time slots and 6 first time slots, and the number of second time slots is equal to the number of uplink time slots, and the 4 second time slots are uplink time slots. If K = 5, it means that the first period includes 5 second time slots and 5 first time slots, and the number of second time slots is greater than the number of uplink time slots, and the 5 second time slots include 4 uplink time slots and 1 flexible time slot.

[0123] Taking SCS of 30 kHz, T = 20, D + Unknown: U = 12:8, and K = 8 or 10 as an example, a first period includes 20 time slots, and according to D + Unknown: U = 12:8, the number of uplink time slots is determined to be 8, and the total number of downlink time slots and flexible time slots is 12. If K = 8, it means that the first period includes 8 second time slots and 12 first time slots, and the number of second time slots is equal to the number of uplink time slots, and the 8 second time slots are uplink time slots. If K = 12, it means that the first period includes 12 second time slots and 8 first time slots, and the number of second time slots is greater than the number of uplink time slots, and the 12 second time slots include 8 uplink time slots and 4 flexible time slots.

[0124] The number of first time slots and second time slots under other configurations in Table 4 can be determined by a similar method, which is not described again here.

[0125] It should be noted that the configuration parameters of the second period and the first period can be pre-defined by a protocol, or the configuration parameters of the second period and the first period can be dynamically configured by signaling. In different embodiments, the configuration parameters of the second period and the first period can be at least two of T, K or N t . For example, the configuration parameters of the second period and the first period can be T and K, the configuration parameters of the second period and the first period can be T and N t , or the configuration parameters of the second period and the first period can be K or N t .

[0126] Since the network device transmits Type0-PDCCH signals in multiple beams in the second period and the first period, the starting slot of the Type0-PDCCH signal transmitted in each beam is described below. In one second period, the starting slot n of the Type0-PDCCH signal corresponding to the ith beam satisfies formula 1: n = (O + floor(i * M) + floor(floor(i * M) / N) * K, i is the serial number of the beam transmitting the Type0-PDCCH signal, which can also be understood as the index serial number of the SSB corresponding to the beam, i ≥ 1 and is an integer. O and M are configuration parameters, O represents the starting slot of a complete Type0-PDCCH signal transmission process of the network device, wherein the complete Type0-PDCCH signal transmission process refers to the process in which all beams of the Type0-PDCCH signal to be transmitted by the network device complete transmission, which can include one or more first periods to match the number of beams of the network device. Alternatively, O can represent the starting slot of the first beam of the network device transmitting the Type0-PDCCH signal. For the network device, M represents the number of Type0-PDCCH signals transmitted in one slot, and M takes any value in the set {1, 1 / 2, 2}, wherein "1" means that the network device transmits one Type0-PDCCH signal in one slot, "1 / 2" means that the network device transmits two Type0-PDCCH signals in one slot, and "2" means that the network device transmits one Type0-PDCCH signal in two slots. For the terminal device, M represents the number of times of listening to the Type0-PDCCH signal in one slot, and M takes any value in the set {1, 1 / 2, 2}, wherein "1" means that the terminal device listens to one Type0-PDCCH signal in one slot, "1 / 2" means that the terminal device listens to two Type0-PDCCH signals in one slot, and "2" means that the terminal device listens to one Type0-PDCCH signal in two slots. The first period N represents the number of slots in one first period, K represents the number of second slots contained in one first period, and floor represents rounding (which can be rounding down or rounding up). The second period.

[0127] The following Table 5 exemplarily provides parameter configurations for a frequency range of 52.6 GHz or above, 52.6 GHz-71 GHZ, or 52.6 GHz-100 GHz, where the frequency range of 52.6 GHz-71 GHZ or 52.6 GHz-100 GHz can be denoted as “FR3” or “extended FR2”. Number of search space sets per slot indicates the number of search spaces in each time slot, and the first symbol index indicates the starting symbol position of the Type0-PDCCH signal carrying CORESET#0, and the terminal device searches for the Type0-PDCCH signal carrying CORESET#0 at the position indicated by the first symbol index, indicates the number of symbols in the time domain of CORESET#0.

[0129]

[0130] In some embodiments, in a first period, a plurality of first time slot groups can be included, different first time slot groups can include different numbers of first time slots, and different first time slot groups can be filled with one or more second time slots. In this way, different numbers of Type0-PDCCH signals can be corresponded to, so as to provide more flexible configuration. Optionally, taking an example that g first time slot groups are included in a first period, the configuration of the first time slot groups can be {N1, N2, … N j}, where j = 1, 2 … g, N j is the number of first time slots included in the jth first time slot group, g ≥ 2, N j ≥ 1, and g and N jis an integer. One first time slot can transmit one or more Type 0-PDCCH signals. For example, the configuration of the first time slot group is {N1, N2}, which means that one first period includes two first time slot groups, the first group includes N1 time slots, corresponding to MxN1 Type 0-PDCCH signals, and the second group includes N2 time slots, corresponding to MxN2 Type 0-PDCCH signals, M is the number of Type 0-PDCCH signals in one first time slot, N1 and N2 are positive integers, N1+N2

[0131] The configuration of the first time slot group can also include the configuration of the second time slot {K1, K2}, which means that K1 second time slots follow the first group, and K2 second time slots follow the second group, and K1 and K2 can be equal or not equal. In some embodiments, the configuration of the first period can also be {N1, K1, N2, K2}. Alternatively, K1 and K2 can also be considered as second time slot groups, specifically, g second time slot groups {K1, K2, …K j} are configured after the aforementioned g first time slot groups. j Kj is the number of second time slots included in the jth second time slot group, Kj j is an integer greater than or equal to 1. The jth second time slot group is located after the jth first time slot group. Exemplarily, the configuration of the first time slot group or the second time slot group described above can be configured by a time slot pattern.

[0132] It should be noted that the first time slot group refers to the combination of multiple first time slots for transmission, which is a possible implementation, and is not used to limit the method provided in the present application. In other embodiments, the first time slot group can be a set of multiple first time slots, referred to as a "first time slot set"; or the first time slot group can be a bundling of multiple first time slots, referred to as a "first time slot bundling"; the second time slot group can be a set of multiple first time slots, referred to as a "second time slot set"; or the second time slot group can be a bundling of multiple second time slots, referred to as a "second time slot bundling". The configuration of the first time slot group or the second time slot group described above can be specified by a protocol or can be carried in a physical broadcast channel (PBCH) for transmission.

[0133] The first time slot and the second time slot can be flexibly configured in the form of time slot groups, and different time slot group configurations can be compatible with different uplink and downlink time slot ratios. Specifically, the configuration of one first time slot group can correspond to different uplink and downlink time slot ratios, in other words, the same first time slot group configuration can be used for different uplink and downlink time slot ratios. For the first time slot configuration {N1, N2} and the second time slot configuration {K1, K2}, the starting time slot n of the Type0-PDCCH signal corresponding to the i-th beam of the network device satisfies formula 2:

[0134] n = (O + floor(i * M) + floor(floor(i * M) / N1) * K1 + floor(floor(i * M) / (N1 + N2) * f(K1, K2), f(K1, K2) = abs(K1 - K2) or f(K1, K2) = K2 - K1

[0135] wherein O and M can be defined with reference to formula 1.

[0136] Exemplarily, the configuration {N1, N2} of the first time slot group can be {4, 3}, {8, 6} or {4, 1}, which will be further described below.

[0140] Taking {N1, N2} as {4, 3} and {K1, K2} as {1, 2} as an example, one first period includes two first time slot groups, one of which includes four first time slots, and one second time slot is located after the four time slots; the other first time slot group includes three first time slots, and two second time slots are located after the three first time slots in the first period. The first period uses the same first time slot group configuration, which can be applied to different uplink and downlink time slot ratio cases, which will be further described below.

[0141] Please refer to Figure 8 , Figure 8For the case that the first period includes 10 slots and the slot ratio is D:U=4:1, the ratio of uplink slots to downlink slots in one first period is 1:4, slots 4 and 9 are uplink slots, and slots 0-3 and 5-8 are downlink slots. {N1, N2} is {4, 3}, wherein the first time slot group 1 includes slots 0-3, the second slot included after the first time slot group 1 is uplink slot 4; the first time slot group 2 includes slots 5-7, and the second slot included after the first time slot group 2 is downlink slot 8 and uplink slot 9. The network device sends Type0-PDCCH signals based on the first time slot group 1 and the first time slot group 2, other terminal devices can send uplink signals in uplink slots 4 and 9, and the network device can send other signals except Type0-PDCCH in downlink slot 8. The first period Figure 8 The configuration mode of other first periods in the second period is similar to that of slots 0-9. Alternatively, Figure 8 The case of D+Unknown:U=4:1 can also be corresponded, wherein slots 4 and 9 are uplink slots, slots 3 and 8 are flexible slots and can be designed as first slots or second slots, and slots 0-2 and 5-7 are downlink slots.

[0142] Please refer to Figure 9 , Figure 9 For the case that the first period includes 10 slots and the slot ratio is D:U=8:2, the ratio of uplink slots to downlink slots in one first period is 2:8, slots 8 and 9 are uplink slots, and slots 0-7 are downlink slots. {N1, N2} is {4, 3}, wherein the first time slot group 1 includes slots 0-3, the second slot included after the first time slot group 1 is downlink slot 4; the first time slot group 2 includes slots 5-7, and the second slot included after the first time slot group 2 is uplink slots 8 and 9. The network device sends Type0-PDCCH signals based on the first time slot group 1 and the first time slot group 2, the network device can send other downlink signals except Type0-PDCCH signals in downlink slot 4, and other terminal devices can send uplink signals in uplink slots 8 and 9. The first period Figure 9 The configuration mode of other first periods in the second period is similar to that of slots 0-9. Alternatively, Figure 9 The case of D+Unknown:U=8:2 can also be corresponded, wherein slot 4 is a flexible slot and can be designed as a first slot or a second slot, slots 8 and 9 are uplink slots, and slots 0-3 and 5-7 are downlink slots.

[0143] It can be seen that when the configuration of the first time slot group {N1, N2} is {4, 3}, the method provided in the present application can be applied to the situation where the uplink and downlink time slot ratio is 1:4, and can also be applied to the situation where the uplink and downlink time slot ratio is 2:8. Therefore, without changing the time slot grouping configuration, it can be applied to scenarios with different uplink and downlink time slot ratios. In other words, for different uplink and downlink time slot ratios, the same time slot grouping configuration method can be used, without the need to perform time slot configuration of Type0-PDCCH signals for different time slot ratios. Such a flexible configuration method can meet the needs of different scenarios and reduce the configuration of time slot patterns, thereby reducing signaling overhead.

[0144] The following is an exemplary description of the configuration of other first time slot groups.

[0145] Taking {N1, N2} as {8, 6} and {K1, K2} as {2, 4} as an example, it means that one first cycle includes two first time slot groups: first time slot groups 1 and 2, where the first time slot group 1 includes 8 first time slots, and 2 second time slots are located after the first time slot group 1; the other first time slot group 2 includes 6 first time slots, and 4 second time slots are located after the first time slot group 2 in the first cycle.

[0146] Please refer to Figure 10 , Figure 10 In the case where the first cycle includes 20 time slots and the time slot ratio is D:U=8:2, the ratio of uplink time slots to downlink time slots in a first cycle is 2:8, time slots 8, 9, 18 and 19 are uplink time slots, and time slots 0 to 7 and 10 to 17 are downlink time slots. {N1, N2} is {8, 6}, where the first time slot group 1 includes time slots 0 to 7, and the second time slots included after the first time slot group 1 are uplink time slots 8 and 9; the first time slot group 2 includes time slots 10 to 15, and the second time slots included after the first time slot group 2 are downlink time slots 16 and 17, and uplink time slots 18 and 19. The network device sends Type0-PDCCH signals based on the first time slot group 1 and the first time slot group 2. The network device can send other downlink signals except Type0-PDCCH signals in downlink time slots 16 and 17. Other terminal devices send uplink signals based on uplink time slots 8, 9, 18 and 19. First cycle Figure 10 The configuration of the other first periods in the second period is similar to that of time slots 0 to 19. Or, Figure 8 It can also correspond to the case of D+Unknown:U=8:2, where time slots 8, 9, 18 and 19 are uplink time slots, time slots 0 to 5 and 10 to 15 are downlink time slots, and time slots 6, 7, 16 and 17 are flexible time slots and can be designed as the first time slot or the second time slot.

[0147] Please refer to Figure 11 , Figure 11For the case of 10 time slots in a first period and time slot ratio D:U=16:4, the ratio of uplink time slots and downlink time slots in one first period is 4:16, time slots 16-19 are uplink time slots, and time slots 0-15 are downlink time slots. {N1, N2} is {8, 6}, wherein the first time slot group 1 comprises time slots 0-7, the second time slot included after the first time slot group 1 is downlink time slots 8 and 9; the first time slot group 2 comprises time slots 10-15, and the second time slot included after the first time slot group 2 is uplink time slots 16-19. The network device sends Type0-PDCCH signals based on the first time slot group 1 and the first time slot group 2, the network device sends other downlink signals except Type0-PDCCH signals based on downlink time slots 8 and 9, and other terminal devices send uplink signals based on uplink time slots 16-19. The first period Figure 11 The configuration of the other first period in the second period is similar to time slots 0-19. Alternatively, Figure 11 The case of D+Unknown:U=16:4 can also be considered, wherein time slots 16-19 are uplink time slots, time slots 0-7 and 10-15 are downlink time slots, and time slots 8 and 9 are flexible time slots. Time slots 8 and 9 are the second time slots and are used for the network device to send other downlink signals except Type0-PDCCH signals.

[0148] It can be seen that when the configuration of the first time slot group is {8, 6}, the method provided in the present application can be applied to the case of uplink time slots and downlink time slots ratio 2:8, and can also be applied to the case of uplink time slots and downlink time slots ratio 4:16, so that for different uplink time slots and downlink time slots ratios, the first time slot group does not need to be configured respectively.

[0149] In some other embodiments, in addition to the case of one first period including two first time slot groups, a first period can also include a larger number of first time slot groups to provide more fine-grained Type0-PDCCH signal transmission configuration and adapt to different scenarios. Taking Table 7 as an example:

[0150] Table 7

[0152] In the following example, {N1, N2, N3, N4} is {4, 3, 4, 1}, and {K1, K2, K3, K4} is {1, 2, 1, 4}. This means that one first cycle includes four first time slot groups: first time slot groups 1 to 4, where first time slot group 1 includes four first time slots and one second time slot is located after first time slot group 1; first time slot group 2 includes three first time slots and two second time slots is located after first time slot group 2; first time slot group 3 includes four first time slots and one second time slot is located after first time slot group 3; and first time slot group 4 includes one first time slot and four second time slots is located after first time slot group 4. This second cycle may also include second time slots, and second time slots may be filled between different first time slot groups. Taking a first cycle including 20 time slots as an example, the 20 time slots are represented by "time slots 0 to 19", where time slots 0 to 3, 5 to 7, 10 to 13 and 15 are first time slots, time slots 4, 8, 9, 14 and 16 to 19 are second time slots, the first time slot group 1 includes time slots 0 to 3, the first time slot group 2 includes time slots 5 to 7, the first time slot group 3 includes 10 to 13, and the first time slot group 4 includes time slot 15.

The network device sends Type0-PDCCH signals based on the first time slot groups 1 to 4, and sends other downlink signals except Type0-PDCCH signals based on downlink time slots 8 and 16 to 18. Other terminal devices send uplink signals in uplink time slots 4, 9, 14 and 19. First cycle Figure 12 The configuration of the other first periods in the second period is similar to that of time slots 0 to 19. Or, Figure 12 It can also correspond to the case of D+Unknown:U=4:1, where time slots 4, 9, 14 and 19 are uplink time slots, time slots 0 to 3, 5 to 7, 10 to 13 and 15 are downlink time slots, and time slots 8, 16 to 18 are flexible time slots and can be designed as the first time slot or the second time slot.

[0154] Please refer to Figure 13 , Figure 13 In the case where the first cycle includes 20 time slots and the time slot ratio is D:U = 8:2, the ratio of uplink time slots to downlink time slots in a first cycle is 2:8, time slots 8-9 and 18-19 are uplink time slots, and time slots 0-7 and 10-17 are downlink time slots. {N1, N2, N3, N4} is {4, 3, 4, 1}, where the first time slot group 1 includes time slots 0-3, and the second time slot after the first time slot group 1 is downlink time slot 4; the first time slot group 2 includes time slots 5-7, and the second time slot after the first time slot group 2 is uplink time slots 8 and 9; the first time slot group 3 includes time slots 10-13, and the second time slot after the first time slot group 3 is downlink time slot 14; the first time slot group 4 includes time slot 15, and the second time slot after the first time slot group 4 is downlink time slots 16 and 17 and uplink time slots 18 and 19. The network device sends Type0-PDCCH signals based on the first time slot group 1 to 4, and sends other downlink signals except Type0-PDCCH signals based on downlink time slots 4, 14, 16 and 17. Other terminal devices send uplink signals based on uplink time slots 8, 9, 18 and 19. First cycle Figure 13 The configuration of the other first periods in the second period is similar to that of time slots 0 to 19. Or, Figure 13 It can also correspond to the case of D+Unknown:U=8:2, where time slots 8, 9, 18 and 19 are uplink time slots, time slots 0 to 3, 5 to 7, 10 to 13 and 15 are downlink time slots, and time slots 4, 14, 16 and 17 are flexible time slots and can be designed as the first time slot or the second time slot.

[0155] Please refer to Figure 14 , Figure 14In the case where the first cycle includes 20 time slots and the time slot ratio is D:U = 16:4, the ratio of uplink time slots to downlink time slots in a first cycle is 4:16, time slots 16 to 19 are uplink time slots, and time slots 0 to 15 are downlink time slots. {N1, N2, N3, N4} is {4, 3, 4, 1}, where the first time slot group 1 includes downlink time slots 0 to 3, and the second time slot after the first time slot group 1 is downlink time slot 4; the first time slot group 2 includes downlink time slots 5 to 7, and the second time slot after the first time slot group 2 is downlink time slots 8 and 9; the first time slot group 3 includes downlink time slots 10 to 13, and the second time slot after the first time slot group 3 is downlink time slot 14; the first time slot group 4 includes downlink time slot 15, and the second time slot after the first time slot group 4 is uplink time slots 16 to 19. The network device sends Type0-PDCCH signals based on the first time slot group 1 to 4, and sends other downlink signals except Type0-PDCCH signals based on downlink time slots 4, 8, 9 and 14. Other terminal devices send uplink signals in uplink time slots 16 to 19. Figure 14 The configuration of the other first periods in the second period is similar to that of time slots 0 to 19. Or, Figure 14 It can also correspond to the case of D+Unknown:U=16:4, where time slots 16 to 19 are uplink time slots, time slots 0 to 3, 5 to 7, 10 to 13 and 15 are downlink time slots, and time slots 4, 8, 9 and 14 are flexible time slots and can be designed as the first time slot or the second time slot.

[0156] It can be seen that when the configuration of the first time slot group is {4, 3, 4, 1}, the method provided in the present application can be applied to the situation where the uplink and downlink time slot ratio is 1:4, the situation where the uplink and downlink time slot ratio is 2:8, and the situation where the uplink and downlink time slot ratio is 4:16. Therefore, there is no need to configure the first time slot group separately for different uplink and downlink time slot ratios, saving signaling overhead.
