Description

Technical Field

[0001] This invention relates to the field of communications, and more specifically, to a method and apparatus for determining and detecting time-domain resources, a storage medium, and an electronic device. Background Technology

[0002] In related technologies, communication uses carrier frequencies higher than those used in fourth-generation (4G) communication systems, such as 28GHz and 45GHz. These high-frequency channels suffer from drawbacks such as higher free propagation loss, susceptibility to oxygen absorption, and significant susceptibility to rain attenuation, severely impacting the coverage performance of high-frequency communication systems. To ensure that high-frequency communication achieves a similar SINR to LTE (Long Term Evolution) systems within their coverage area, it is necessary to guarantee the antenna gain of high-frequency communication. Fortunately, because the carrier frequencies corresponding to high-frequency communication have shorter wavelengths, more antenna elements can be accommodated per unit area. More antenna elements mean that beamforming techniques can be used to improve antenna gain, thereby ensuring the coverage performance of high-frequency communication.

[0003] By employing beamforming, the transmitting end can concentrate its transmission energy in a specific direction, while consuming little or no energy in other directions. In other words, each beam has its own directionality, and each beam can only cover terminals in a certain direction. The transmitting end, i.e., the base station, needs to transmit multiple beams to achieve omnidirectional coverage. Typically, the number of beams is in the dozens or even hundreds. To meet the access needs of terminals that may appear in various directions, omnidirectional coverage of system broadcast messages must be achieved. Communication stations need to repeatedly transmit the same system broadcast message in each beam direction. For communication stations, this also presents the problem of increased "absolute overhead" of system broadcast messages.

[0004] In next-generation wireless communication (NR) systems, system information is divided into minimum system information (Minimum SI) and other system information (Other SI). Minimum SI is further divided into "Main System Information (MIB)" carried on the Physical Broadcast Channel (PBCH) and "Remaining Minimum SI (RMSI)" carried on the Physical Downlink Shared Channel (PDSCH). RMSI is carried on the PDSCH and scheduled by the corresponding Physical Downlink Control Channel (PDCCH). The Main SI provides basic cell system parameters, while the Remaining Minimum SI provides initial access-related configuration information, such as the initial access request transmission configuration and the initial access response message reception configuration. Other system information that needs to be broadcast is called Other SI. Regarding the transmission of RMSI, such as... Figure 1 As shown, Figure 1This is a schematic diagram of RMSI transmission in the related technology of this invention. The standard supports time-division multiplexing or frequency-division multiplexing between RMSI and the synchronization signal physical broadcast channel block (SS / PBCH block, abbreviated as SSB).

[0005] For time-division multiplexing, such as Figure 2 As shown, Figure 2 This is a schematic diagram of time-division multiplexing (TDD) transmission of RMSI in the related technology of this invention. During the duration of RMSI transmission, it is very likely to overlap with the transmission of synchronization signal blocks, and the two may even be mapped to the same time slot. Regarding RMSI PDSCH reception, the current standard explicitly states that when a terminal receives PDSCH according to the instructions in the RMSI PDSCH resource allocation, it does not assume that it contains resources used for SSB transmission. This does not mean that RMSI transmission has a higher priority than SSB, but rather that the base station needs to consider the resources occupied by SSB when allocating RMSI resources and avoid scheduling RMSI PDSCH on resources occupied by SSB. The reason is that when receiving RMSI, the terminal cannot yet know the actual transmission location information of the SSB. Therefore, when the resources of the two overlap, the terminal cannot perform rate-matched RMSI PDSCH reception according to the resource location of the SSB.

[0006] Under the time-domain resource allocation method in related technologies, only a certain number of consecutive symbols within a time slot are supported for PDSCH. Considering the above-mentioned special characteristics, for RMSI transmission, when SSB appears in the middle symbol of a time slot, the resource allocation of RMSI PDSCH will be greatly limited, and it may even be impossible to achieve RMSI PDSCH transmission within a certain time slot. Therefore, the time-domain resource allocation method in related technologies is not suitable for RMSI.

[0007] There are currently no effective solutions to the aforementioned problems in the relevant technologies. Summary of the Invention

[0079] Example 3

[0080] In this embodiment, the first channel signal is the synchronization signal physical broadcast channel block (SS / PBCH block, abbreviated as SSB). The mapping pattern of the SSB in the time slot can differ under different subcarrier intervals, including:

[0081] Case A: As Figure 5 As shown, Figure 5 This is the mapping of SSB in time slots in this embodiment of the invention. Figure 1This is an SSB mapping pattern corresponding to a 15kHz subcarrier spacing, illustrating the transmission resources of each SSB. A 15kHz slot (i.e., 14 15kHz symbols, symbol 0-symbol 13) contains two SSBs, each occupying 4 15kHz symbols, and mapped to symbol 2-symbol 5 and symbol 8-symbol 11 respectively.

[0082] Case B: As Figure 6 As shown, Figure 6 This is the mapping of SSB in time slots in this embodiment of the invention. Figure 2 This is an SSB mapping pattern corresponding to a 30kHz subcarrier spacing, illustrating the transmission resources of each SSB. It contains 4 SSBs within two 30kHz slots (i.e., 28 30kHz symbols, two symbols 0-symbol 13), each occupying 4 30kHz symbols, and mapped to symbols 4-7 and 8-11 in the first slot, and symbols 2-5 and 6-9 in the second slot, respectively.

[0083] Case C: As Figure 7 As shown, Figure 7 This is the mapping of SSB in time slots in this embodiment of the invention. Figure 3 This is another SSB mapping pattern corresponding to the 30kHz subcarrier spacing, illustrating the transmission resources of each SSB. It contains 4 SSBs within two 30kHz slots (i.e., 28 30kHz symbols, two symbols 0-symbol 13), each occupying 4 30kHz symbols, and mapped to symbols 2-5 and 8-11 in the first slot, and symbols 2-5 and 8-11 in the second slot, respectively.

[0084] Case D: As Figure 8 As shown, Figure 8 This is the mapping of SSB in time slots in this embodiment of the invention. Figure 4This is an SSB mapping pattern corresponding to a 120kHz subcarrier spacing, illustrating the transmission resources of each SSB. It contains 4 SSBs within two 120kHz slots (i.e., 28 120kHz symbols, two symbols 0-symbol 13), each occupying 4 120kHz symbols, and mapped to symbols 4-7 and 8-11 in the first slot, and symbols 2-5 and 6-9 in the second slot, respectively.

[0085] Case E: As Figure 9 As shown, Figure 9 This is the mapping of SSB in time slots in this embodiment of the invention. Figure 5 This is an SSB mapping pattern corresponding to a 240kHz subcarrier spacing, illustrating the transmission resources of each SSB. It contains 8 SSBs within two 120kHz slots (i.e., 56 240kHz symbols, symbol 0-symbol 55), each occupying 4 240kHz symbols. The symbols are numbered within the aforementioned time period (56 symbols), and the 8 SSBs are mapped to symbol 8-symbol 11, symbol 12-symbol 15, symbol 16-symbol 19, symbol 20-symbol 23, symbol 32-symbol 35, symbol 36-symbol 39, symbol 40-symbol 43, and symbol 44-symbol 47 respectively.

[0086] The above description illustrates the symbol occupancy when the SSB is mapped to a time slot with the same subcarrier spacing. When the SSB is mapped to a time slot with a different subcarrier spacing, the absolute time position occupied by the SSB remains unchanged, but the occupied symbol index needs to be transformed to the symbol index of the target subcarrier spacing.

[0087] For example, as shown in Table 1, when a 15kHz SSB is mapped to a 30kHz slot, the two 30kHz slots contain two SSBs, which occupy the symbols: symbol 4-symbol 11 for the first 30kHz slot and symbol 2-symbol 9 for the second 30kHz slot.

[0088] Table 1

[0089]

[0090] For the RMSI reception process, it can be considered that the SSB under a certain subcarrier interval is mapped to the time slot corresponding to the RMSI subcarrier interval. In subsequent embodiments, the time domain allocation position will be described for different combinations of SSB and RMSI subcarrier intervals.

[0091] In this context, pattern 1 is a time-division multiplexing of SSB and RMSI, as shown in Table 2. For pattern 1, there are the following RMSI search space symbol counts and positions, and the search space is used to carry RMSIPDCCH. Among them, gray DC represents the second search space position within a slot. Note: Within a slot, it can also refer to sending the PDCCH within the second search space (i.e., corresponding to configuration 13-19).

[0092] Table 2

[0093]

[0094]

[0095] This embodiment provides a time-domain resource allocation method and system, including: non-contiguous PDSCH time-domain resource allocation; defining an RMSI time-domain resource allocation list for different subcarrier spacing combinations; defining time-domain resource allocation considering the mapping position of synchronization signal blocks in the time slot; and supporting PDCCH scheduling of PDSCH located in the preceding symbol within the same time slot.

[0096] This embodiment also includes the following implementation schemes, used to illustrate the scheme of this embodiment under different SCS and SCS combinations:

[0097] Implementation method 1: SCS{SSB,RMSI}={15,15}kHz

[0098] Table 3 shows the mapping positions of SSBs in the slot and the possible spatial locations of RMSI search for the subcarrier spacing combination SCS{SSB,RMSI}={15,15}kHz. Based on this, a diagram of the RMSIPDSCH time-domain allocation is further given when some or all SSBs are present.

[0099] Table 3

[0100]

[0101] As shown in Table 4, Dc represents the symbol of the RMSI search space within a time slot. For Searchspacelocations 1, 2, 4, and 10, the symbol position does not exceed the second symbol, so we group them together. For Searchspacelocations 3, 5, and 6, the last symbol is the third symbol, so we group them together. When a slot contains two search spaces, the second one is shown in gray. SSB represents the symbol mapped by the SSB. Dd represents the symbol occupied by the PDSCH. When a slot contains two search spaces, the symbol occupied by the PDSCH allocated by the PDCCH in the second search space is shown in gray.

[0102] Table 4

[0103]

[0104] Table 5 shows the possible time-domain resource allocation patterns when there is no mapped SSB in the slot where the RMSI is located.

[0105] Table 5

[0106]

[0107]

[0108] The labels for Dc and SSB symbols in Tables 4 and 5 are hidden, leaving only the PDSCH symbol label (i.e., Dd). Each row in the tables corresponds to a time-domain resource allocation pattern; that is, the set of symbols labeled Dd in each row is defined as a time-domain resource allocation pattern. Merging identical resource allocation patterns yields the time-domain resource allocation pattern set shown in Table 6. Table 6 presents the possible time-domain resource allocation pattern set for the SCS combination {SSB,RMSI} = {15,15}kHz, totaling 34 patterns. Several patterns can be selected from these, and the corresponding number of bits can be used in the RMSI PDCCH for time-domain allocation indication. For example, 32 patterns can be selected as the default time-domain resource allocation pattern set for RMSI, and 5 bits can be used to indicate the currently used PDSCH time-domain resource allocation pattern to the terminal. For example, in the standard, 15 types are defined as the default time-domain resource allocation pattern set of RMSI. Correspondingly, 4 bits are used to indicate to the terminal the PDSCH time-domain resource allocation pattern currently used. At this time, there is a state as a reserved state.

[0109] Table 6

[0110]

[0111]

[0112] In the time-domain resource allocation pattern indication method described in this embodiment, for a specific combination of a first SCS (corresponding to an SSB) and a second SCS (corresponding to at least one of the following RMSI / OSI / paging / msg2 / msg4, etc.), the time-domain resource allocation pattern when the time slot contains an SSB (Table 4) and the time-domain resource allocation pattern when the time slot does not contain an SSB (Table 5) are merged into a time-domain resource allocation pattern set. Downlink control information (DCI) signaling is used to indicate the currently used time-domain resource allocation pattern to the terminal within the aforementioned set. Different combinations of the first SCS and the second SCS can correspond to the same or different time-domain resource allocation pattern sets used for the second signal channel.

[0113] In other implementations, multiple time-domain resource allocation pattern sets can be defined for combinations of the first SCS and the second SCS (including: one combination of the first SCS and the second SCS corresponding to multiple time-domain resource allocation pattern sets, or multiple combinations of the first SCS and the second SCS corresponding to multiple time-domain resource allocation pattern sets). The DCI signaling first indicates to the terminal which time-domain resource allocation pattern set is being used, and then further indicates to the terminal within the specified set which time-domain resource allocation pattern is currently being used. For example, two time-domain resource allocation pattern sets can be defined, corresponding to the time-domain resource allocation pattern when the time slot contains an SSB (Table 4) and the time-domain resource allocation pattern when the time slot does not contain an SSB (Table 5), respectively. In the downlink control information (DCI), 1 bit is used to indicate to the terminal the currently used time-domain resource allocation pattern set, and the currently used time-domain resource allocation pattern is further indicated within the aforementioned time-domain resource allocation pattern set. At this point, the terminal determines the sets of time-domain resource allocation patterns based on the first SCS (which may correspond to a frequency band; the terminal can determine the first SCS based on the frequency band to which the current first signal channel belongs, or the terminal can determine the first SCS by blindly detecting the first channel signal, i.e., using different SCSs to detect the first signal channel and determining the value of the first SCS based on whether the detection is successful) and the second SCS (which may be an SCS notified by the base station, such as the second SCS notified in the physical broadcast channel, or it may be a predefined one or correspond to a frequency band). The terminal then determines which specific time-domain resource allocation pattern set it is based on the DCI indication.

[0114] For time-domain allocation patterns that do not contain SSBs within the time slots described above, existing time-domain resource allocation indication methods can also be used, i.e., using the parameter 'start and length indicator (SLIV)' to indicate the current time-domain resource allocation. Each SLIV index corresponds to a symbol allocation scheme, uniquely indicating the starting symbol and the number of allocated symbols. For time-domain resource allocation patterns that contain SSBs within the time slots, the indication can still be provided by listing time-domain resource allocation patterns in a table, combined with DCI signaling.

[0115] In other implementations, instead of using information bits in the downlink control information to indicate the currently used time-domain resource allocation pattern set, a correspondence between time slot types and time-domain resource allocation pattern sets can be defined. For example, time slots can be divided into two categories: time slots containing first channel signal (SSB) transmission resources and time slots not containing first channel signal (SSB) transmission resources. In this case, for time slots containing first channel signal (SSB) transmission resources, the terminal determines the "time-domain resource allocation pattern when the time slot contains SSB (Table 4)" as the currently used time-domain resource allocation pattern set; for time slots not containing first channel signal (SSB) transmission resources, the terminal determines the "time-domain resource allocation pattern when the time slot does not contain SSB (Table 5)" as the time-domain resource allocation pattern set. Furthermore, the base station uses downlink control information to indicate the currently used time-domain resource allocation pattern to the terminal.

[0116] Specifically, under a certain combination of a first SCS and a second SCS, multiple sets of time-domain resource allocation patterns are defined. Furthermore, the terminal determines which set of time-domain resource allocation patterns is used for the current time slot based on the current time slot type.

[0117] Since the terminal does not know whether an SSB was actually transmitted within a time slot containing SSB transmission resources, the criterion for distinguishing time slot types is "whether it contains first channel signal (SSB) transmission resources," rather than "whether it contains first channel signal (SSB)."

[0118] In other implementations, the currently used time-domain resource allocation pattern set can be notified only through DCI signaling. That is, the time-domain resource allocation pattern set is not related to the SCS combination, and the defined multiple time-domain resource allocation pattern sets are applicable to all combinations of the first SCS and the second SCS. The currently used time-domain resource allocation pattern set is notified only through signaling.

[0119] In other implementations, the set of time-domain resource allocation patterns currently used can be determined solely by the time slot type, meaning that the set of time-domain resource allocation patterns is not related to the SCS combination and does not require signaling notification.

[0120] In other implementations, the time-domain resource allocation pattern set can be determined by combining the time slot type with DCI signaling. That is, multiple time-domain resource allocation pattern sets are determined by the time slot type, and the DCI signaling is used to notify which time-domain resource allocation pattern set is currently used; or, a set of time-domain resource allocation pattern sets is indicated by DCI signaling, and the UE determines which time-domain resource allocation pattern set is currently used by using the time slot type.

[0121] In other implementations, the time-domain resource allocation pattern set can be determined by combining SCS combination, time slot type, and DCI signaling.

[0122] Note: Regardless of the method used to determine the set of time-domain resource allocation patterns, the correspondence between the set of time-domain resource allocation patterns and the indication method must be predefined. This predefinition can be specified in the protocol.

[0123] Note: The DCI signaling mentioned above can also be signaling carried on other carriers, such as Radio Resource Control (RRC) signaling on other carriers.

[0124] The above description also applies to other implementation methods.

[0125] Implementation Method 2: SCS{SSB,RMSI}={15,30}kHz

[0126] Table 7 shows the mapping positions of SSBs in a slot and the possible RMSI search space positions (i.e., Dc is the symbol where the RMSI search space is located within the slot) under the subcarrier spacing combination SCS{SSB,RMSI}={15,30}kHz. Based on this, the diagram of RMSI PDSCH time-domain allocation is further given when some or all SSBs are present. Among them, for Searchspacelocations 1, 2, 4, 10, the symbol positions do not exceed the second symbol, so we consider them as one category. For Searchspacelocations 3, 5, 6, the last symbol is the third symbol, so we consider them as another category. When a slot contains two search spaces, the second one is indicated in gray. SSB represents the symbol mapped by the SSB. Dd represents the symbol occupied by the PDSCH. When a slot contains two search spaces, the symbol occupied by the PDSCH allocated by the PDCCH in the second search space is indicated in gray.

[0127] Table 7

[0128]

[0129] When there is no mapped SSB in the slot where the RMSI is located, the possible time-domain resource allocation methods are still shown in Table 5.

[0130] The labels for Dc and SSB symbols in Tables 7 and 5 are hidden, leaving only the PDSCH symbol label (i.e., Dd). Each row in the table corresponds to a time-domain resource allocation pattern; that is, the set of symbols labeled Dd in each row is defined as a time-domain resource allocation pattern. Merging identical resource allocation methods yields the time-domain resource allocation table shown in Table 8. Table 8 presents 28 possible time-domain resource allocation methods under the SCS combination {SSB,RMSI}={15,30}kHz. Several methods can be selected from these and used to indicate the time-domain allocation in the RMSI PDCCH using the corresponding number of bits. For example, 5 bits can be used to indicate the currently used PDSCH time-domain resource allocation to the terminal, with 4 states as reserved states. Furthermore, to reduce the bit overhead of time-domain resource allocation, the standard defines 16 of these as the default time-domain resource allocation methods for RMSI, correspondingly using 4 bits to indicate the currently used PDSCH time-domain resource allocation to the terminal.

[0133] Implementation Method 3: SCS{SSB,RMSI}={30,15}kHz

[0134] Table 9 shows the mapping positions of SSBs in the slot under the subcarrier spacing combination SCS{SSB,RMSI}={30,15}kHz, as well as the possible RMSI search space positions (i.e., Dc is the symbol where the RMSI search space is located within the time slot). Based on this, the time-domain allocation pattern of RMSI PDSCH is further given when some or all SSBs are present. The space location index comes from Table 3. For Searchspace locations 1, 2, 4, 10, the symbol positions do not exceed the second symbol, so we group them together. For Searchspace locations 3, 5, 6, the last symbol is the third symbol, so we group them together. When a slot contains two search spaces, the second one is shown in gray. SSB represents the symbol mapped by the SSB; Dd represents the symbol occupied by the PDSCH. When a slot contains two search spaces, the symbol occupied by the PDSCH allocated by the PDCCH in the second search space is shown in gray.

[0135] Table 9

[0136]

[0137]

[0138] Table 10 shows the mapping positions of SSBs in the slot under SSB mapping pattern 1, as well as the possible RMSI search space positions (i.e., Dc is the symbol where the RMSI search space is located within the time slot). Based on this, a diagram of the RMSI PDSCH time domain allocation is further given when some or all SSBs are present.

[0139] When SSB0 is actually transmitted, for search space location 1, it is equivalent to the case of search space location 3 without SSB. This is not specifically listed in Table 10.

[0140] Table 10

[0141] Only SSB0 and SSB3 differ from the positions in pattern 1.

[0142]

[0143]

[0144] When there is no mapped SSB in the slot where the RMSI is located, the possible time-domain resource allocation methods are still shown in Table 5.

[0145] The labels for Dc and SSB symbols in Tables 9, 10, and 5 are hidden, leaving only the PDSCH symbol label (i.e., Dd). Each row in the table corresponds to a time-domain resource allocation pattern; that is, the set of symbols labeled Dd in each row is defined as a time-domain resource allocation pattern. Merging identical resource allocation methods yields the time-domain resource allocation table shown in Table 11. Table 8 presents 62 possible time-domain resource allocation methods for the SCS combination {SSB, RMSI} = {30, 15} kHz. Several methods can be selected from these and used to indicate the time-domain allocation in the RMSI PDCCH using the corresponding number of bits. For example, in the standard, 6 bits are used to indicate the currently used PDSCH time-domain resource allocation pattern to the terminal, with two states as reserved time-domain resource allocation patterns. Furthermore, to reduce the bit overhead of time-domain resource allocation, the standard defines 16 of these as the default time-domain resource allocation methods for RMSI, correspondingly using 4 bits to indicate the currently used PDSCH time-domain resource allocation to the terminal.

[0146] In addition, Table 11 is the complete set of RMSI PDSCH time-domain resource allocation under subcarrier spacing combination {SSB,RMSI}={30,15}kHz. RMSI PDSCH time-domain resource allocation tables can also be defined separately for different mapping patterns (i.e. pattern 1 and pattern 2) of 30kHz SSB, thereby reducing indication overhead.

[0147] In addition, separate resource allocation tables are defined for different search space types. For example, different time-domain resource allocation tables are defined as follows: a time slot contains only one search space; a time slot contains two search spaces, and the PDCCH is contained in the first search space; a time slot contains two search spaces, and the PDCCH is contained in the second search space.

[0148] Table 11

[0149]

[0150]

[0151] Implementation Method 4: SCS{SSB,RMSI}={30,30}kHz

[0152] With subcarrier spacing combination SCS{SSB,RMSI}={30,30}kHz, Tables 12 and 13 show the mapping positions of SSBs in the slot under SSB mapping pattern 1, as well as the possible RMSI search space positions (i.e., Dc is the symbol where the RMSI search space is located within the time slot). Based on this, the time-domain allocation pattern of RMSI PDSCH is further given when some or all SSBs are present. The space location index comes from Table 3. For Searchspace locations 1, 2, 4, and 10, the symbol positions do not exceed the second symbol, so we group them together. For Searchspace locations 3, 5, and 6, the last symbol is the third symbol, so we group them together. When a slot contains two search spaces, the second one is indicated in gray. SSB represents the symbol mapped by the SSB; Dd represents the symbol occupied by the PDSCH. When a slot contains two search spaces, the symbol occupied by the PDSCH allocated by the PDCCH in the second search space is indicated in gray.

[0153] Table 12

[0154]

[0155] Table 13

[0156]

[0157] When there is no mapped SSB in the slot where the RMSI is located, the possible time-domain resource allocation methods are still shown in Table 5.

[0158] The Dc and SSB symbols in Tables 12, 13, and 5 are hidden, leaving only the PDSCH symbol label (i.e., Dd). Each row in the table corresponds to a time-domain resource allocation pattern; that is, the set of symbols labeled Dd in each row is defined as a time-domain resource allocation pattern. Merging identical resource allocation methods yields the time-domain resource allocation table shown in Table 14. As for the possible time-domain resource allocation methods under the SCS combination {SSB,RMSI}={30,30}kHz, there are 53 possible methods. Several can be selected from these, and the corresponding number of bits is used in the RMSI PDCCH for time-domain allocation indication. For example, in the standard, 6 bits are used to indicate the currently used PDSCH time-domain resource allocation to the terminal, with 11 of them defined as reserved states. Furthermore, to reduce the bit overhead of time-domain resource allocation, the standard defines 16 of these as the default time-domain resource allocation methods for RMSI, correspondingly using 4 bits to indicate the currently used PDSCH time-domain resource allocation to the terminal.

[0159] In the implementation method 1 for the 30kHz SSB pattern 2, the time-domain resource allocation is the same under the subcarrier spacing combination {SSB,RMSI}={15,15}kHz, and Table 6 can be reused as the complete set of time-domain resource allocation configuration under the 30kHz SSB pattern 2.

[0160] Table 14

[0161]

[0162]

[0163] Implementation Method 5: SCS{SSB,RMSI}={120,60}kHz

[0164] Table 15 shows the mapping positions of SSBs in a slot and the possible RMSI search space positions (i.e., Dc is the symbol where the RMSI search space is located within the slot) under the subcarrier spacing combination SCS{SSB,RMSI}={120,60}kHz. Based on this, the diagram of RMSI PDSCH time-domain allocation is further given when some or all SSBs are present. Among them, for Searchspace locations 1, 2, 4, 10, the symbol positions do not exceed the second symbol, so we consider them as one category. For Searchspace locations 3, 5, 6, the last symbol is the third symbol, so we consider them as another category. When a slot contains two search spaces, the second one is indicated in gray. SSB represents the symbol mapped by the SSB. Dd represents the symbol occupied by the PDSCH. When a slot contains two search spaces, the symbol occupied by the PDSCH allocated by the PDCCH in the second search space is indicated in gray.

[0165] The temporal resource allocation under search space locations 1-9 in the table is the same as that in implementation method 3, where the 30kHz SSB mapping pattern 1 is the same, so it will not be listed again here.

[0166] Table 15

[0167]

[0168]

[0169] When there is no mapped SSB in the slot where the RMSI is located, the possible time-domain resource allocation methods are still shown in Table 5.

[0170] The Dc and SSB symbols in Tables 15 and 5 are hidden, and only the PDSCH symbol (i.e., Dd) is retained. Each row in the table corresponds to a time-domain resource allocation pattern, that is, the set of symbols marked as Dd in each row is defined as a time-domain resource allocation pattern. Merging the same resource allocation methods yields the time-domain resource allocation table shown in Table 16. As for the possible time-domain resource allocation methods under the SCS combination {SSB,RMSI}={30,30}kHz, there are a total of 54. In addition, for the time-domain resource allocation under search spacelocations 1-9, which is the same as the 30kHz SSB mapping pattern 1 in implementation method 3, the resource allocation corresponding to the above search space in Table 11 needs to be merged with these 54 to form the complete set of time-domain resource allocations. Several types can be selected from this set, and the corresponding number of bits is used in the RMSI PDCCH to indicate the time-domain allocation. For example, in the standard, 6 bits are used to indicate the currently used PDSCH time-domain resource allocation to the terminal, and 10 of them are defined as reserved states. For example, in order to reduce the bit overhead of time-domain resource allocation, the standard defines 16 time-domain resource allocation methods as the default for RMSI, and uses 4 bits to indicate to the terminal the PDSCH time-domain resource allocation currently used.

[0174] Implementation method 6: SCS{SSB,RMSI}={120,120}kHz

[0175] Table 17 shows the mapping positions of SSBs in the slot and the possible RMSI search space positions (i.e., Dc is the symbol where the RMSI search space is located within the time slot) under the subcarrier spacing combination SCS{SSB,RMSI}={120,120}kHz. Based on this, a diagram of the RMSI PDSCH time-domain allocation is further given when some or all SSBs are present. The case of search spacelocation{1,2,4,5,7,8} is the same as the resource allocation of the corresponding search space in Tables 12 and 13, and will not be repeated here.

[0176] When a slot contains two search spaces, the second one is indicated in gray; SSB represents the symbol mapped by SSB; Dd represents the symbol occupied by PDSCH. When a slot contains two search spaces, the symbol occupied by PDSCH allocated by PDCCH in the second search space is indicated in gray.

[0177] Table 17

[0178]

[0179] When there is no mapped SSB in the slot where the RMSI is located, the possible time-domain resource allocation methods are still shown in Table 5.

[0180] The Dc and SSB symbols in Tables 17 and 5 are hidden, leaving only the PDSCH symbol label (i.e., Dd). Each row in the table corresponds to a time-domain resource allocation pattern; that is, the set of symbols labeled Dd in each row is defined as a time-domain resource allocation pattern. Merging identical resource allocation methods yields the time-domain resource allocation table shown in Table 18. As for the possible time-domain resource allocation methods under the SCS combination {SSB,RMSI}={120,120}kHz, there are 31 possible methods. Additionally, for the search spacelocation {1,2,4,5,7,8}, the resource allocation information corresponding to the search space in Tables 12 and 13 needs to be merged with the above 31 resource configurations to form the complete set of time-domain resource allocations. Several methods can be selected from this set, and the corresponding number of bits is used in the RMSI PDCCH to indicate the time-domain allocation. For example, in the standard, 6 bits are used to indicate the currently used PDSCH time-domain resource allocation to the terminal, with 10 of them defined as reserved states. For example, in order to reduce the bit overhead of time-domain resource allocation, the standard defines 16 time-domain resource allocation methods as the default for RMSI, and uses 4 bits to indicate to the terminal the PDSCH time-domain resource allocation currently used.

[0183] Implementation Method 7: SCS{SSB,RMSI}={240,60}kHz

[0184] Table 19 shows the mapping positions of SSBs in the slot and the possible RMSI search space positions (i.e., Dc is the symbol where the RMSI search space is located within the time slot) under the subcarrier spacing combination SCS{SSB,RMSI}={240,60}kHz. Based on this, a diagram of the RMSI PDSCH time domain allocation is further given when some or all SSBs are present.

[0185] At this point, an RMSI slot contains 8 SSBs. To simplify the number of possible time-domain allocation patterns, it is assumed that four consecutive SSBs (i.e., SSB0 to SSB3, or SSB4 to SSB7) have the same actual transmission status. In this case, if any SSB from SSB0 to SSB3 is actually transmitted, the base station will treat it as if all SSB0 to SSB3 have been transmitted when allocating time-domain resources for RMSI PDSCH. The same logic applies to SSB4 to SSB7. Table 19 shows different time-domain allocation patterns. When a slot contains two search spaces, the second one is indicated in gray; SSB represents the symbol mapped by the SSB; Dd represents the symbol occupied by the PDSCH. When a slot contains two search spaces, the symbol occupied by the PDSCH allocated by the PDCCH in the second search space is indicated in gray.

[0186] Table 19

[0187]

[0188] The Dc and SSB symbols in Tables 19 and 5 are hidden, leaving only the PDSCH symbol label (i.e., Dd). Each row in the table corresponds to a time-domain resource allocation pattern; that is, the set of symbols labeled Dd in each row is defined as a time-domain resource allocation pattern. Merging identical resource allocation methods yields the time-domain resource allocation table shown in Table 20. As a complete set of 32 possible time-domain resource allocation methods under the SCS combination {SSB,RMSI}={240,60}kHz, several can be selected and indicated in the RMSI PDCCH using the corresponding number of bits. For example, in the standard, 5 bits are used to indicate the currently used PDSCH time-domain resource allocation to the terminal, defining the correspondence between various time-domain resource allocation patterns and the value of the indicator bits. For example, in order to reduce the bit overhead of time-domain resource allocation, the standard defines 16 time-domain resource allocation methods as the default of RMSI, defines the correspondence between various time-domain resource allocation patterns and indicator bit values, and uses 4 bits to indicate to the terminal the PDSCH time-domain resource allocation currently used.

Based on this, a diagram of the RMSI PDSCH time domain allocation is further given when some or all SSBs are present.

[0193] In this context, when a slot contains two search spaces, the second one is indicated in gray; SSB represents the symbol mapped by SSB; Dd represents the symbol occupied by PDSCH. When a slot contains two search spaces, the symbol occupied by PDSCH allocated by PDCCH in the second search space is indicated in gray.

[0197] The Dc and SSB symbols in Tables 21 and 5 are hidden, leaving only the PDSCH symbol label (i.e., Dd). Each row in the table corresponds to a time-domain resource allocation pattern; that is, the set of symbols labeled Dd in each row is defined as a time-domain resource allocation pattern. Merging identical resource allocation methods yields the time-domain resource allocation table shown in Table 22. As a complete set of 39 possible time-domain resource allocation methods under the SCS combination {SSB,RMSI}={240,120}kHz, several can be selected and used in the RMSI PDCCH for time-domain allocation indication using the corresponding number of bits. For example, in the standard, 5 bits are used to indicate the currently used PDSCH time-domain resource allocation to the terminal, selecting 32 time-domain resource allocation patterns and defining the correspondence between various time-domain resource allocation patterns and the indicator bit values. For example, in order to reduce the bit overhead of time-domain resource allocation, the standard defines 16 time-domain resource allocation methods as the default of RMSI, defines the correspondence between various time-domain resource allocation patterns and indicator bit values, and uses 4 bits to indicate to the terminal the PDSCH time-domain resource allocation currently used.

[0201] Implementation Method 9:

[0202] For the transmission of the second signal channel and its corresponding downlink control information, the network side configures one or more Physical Downlink Control Channel (PDCCH) monitoring windows, each associated with a different Sub-Session Block (SSB). The terminal determines the location of the monitoring window carrying the second channel signal corresponding to that SSB based on the reception of the SSB. The second channel signal includes at least one of the following: a Physical Downlink Shared Channel (PDSCH) carrying Residual Minimum System Information (RMSI), a PDSCH carrying paging information, a PDSCH carrying Other System Information (OSI), a PDSCH carrying Random Access Response Information (RAR), a PDSCH carrying Random Access Collision Resolution Information (RAR), a PDSCH carrying MSG2, and a PDSCH carrying MSG4.

[0203] Within a configured monitoring window, the terminal detects downlink control information (DCI) corresponding to the second channel signal according to the search space configuration. The monitoring window contains one or more time slots, and overlaps may exist between different monitoring windows when multiple time slots are present. In this case, a single monitoring window may contain multiple second channel signals (corresponding to different SSBs). Second channel signals with quasi-co-location relationships (QCL) with the detected SSBs have higher detection performance, but the terminal may first detect a second channel signal within the monitoring window that corresponds to other SSBs. Even if correctly received, this could lead to unsuccessful access. Therefore, the terminal cannot assume that only one second channel signal is transmitted within multiple time slots of a monitoring window. That is, the terminal needs to detect the downlink control information of the second channel signal within one or more time slots of the monitoring window corresponding to the second channel signal.

[0204] Specifically, when the terminal encounters the following situation in the subsequent process, it needs to continue to detect the downlink control information of the second channel signal in other time slots in the monitoring window.

[0205] Sub-example 1: If the terminal correctly detects the downlink control information of the second channel signal in a certain time slot of the monitoring window, but fails to correctly detect the second channel signal, the downlink control information of the second channel signal correctly monitored by the terminal may not be the transmission of the downlink port or beam direction to which the terminal belongs (i.e., the successfully received downlink control information does not have a quasi-co-location (QCL) relationship with the SSB previously detected by the terminal, but is successfully received by the terminal only due to the overlap of the monitoring windows). Therefore, the terminal needs to continue to detect the downlink control information of the second channel signal in other time slots of the monitoring window.

[0206] In Sub-Example 2, if the terminal correctly detects the downlink control information of the RMSI and the RMSI itself, and performs preamble transmission according to the random access configuration configured in the RMSI, but fails to correctly detect the random access response information, the possible reason is that the RMSI received by the terminal does not have a quasi-co-location (QCL) relationship with the SSB previously detected by the terminal. That is, it is not the RMSI the terminal intends to receive. Therefore, the random access request (preamble) sent according to the configuration in this RMSI is incorrect, and the base station will not reply with the corresponding random access response information. Consequently, the terminal continues to detect the downlink control information of the RMSI in other time slots within the monitoring window corresponding to the first channel signal, and determines the subsequent random access request and reception configuration based on the new reception.

[0207] In this application, the technical features of the various embodiments can be combined and used in one embodiment without conflict. Each embodiment is merely the preferred embodiment of this application.

[0208] This scheme presents a time-domain resource allocation method and system. Considering the mapping pattern of synchronization signal blocks to time slots under different subcarrier spacing combinations, a time-domain resource allocation scheme that does not conflict with the transmission resources of synchronization signal blocks is derived.

[0209] The solution in this embodiment avoids the resource allocation limitations of RMSI PDSCH caused by existing time-domain resource allocation methods that only support a certain number of consecutive symbols occupied by PDSCH within a time slot. It provides efficiency and flexibility in resource allocation. Furthermore, by defining separate time-domain resource allocation lists for different subcarrier spacing combinations, the overhead of time-domain resource allocation is significantly reduced. This effectively supports time-domain resource allocation for RMSI PDSCH.
