Description

[Technical field]

[0001] This disclosure claims priority from Chinese Patent Application No. 201810301332.1, filed with the China Patent Office on April 4, 2018, the entire contents of which are incorporated herein by reference.

[0002] Technical Field The present disclosure relates to the field of communications, and in particular to a time domain resource determination and detection method and apparatus, a storage medium, and an electronic device. [Background technology]

[0003] background In the related art, communication is carried out at a carrier frequency such as 28 GHz or 45 GHz, which is higher than the carrier frequency used in the fourth generation (4G) mobile communication system. This high frequency channel has the disadvantages of large free propagation loss, easy absorption by oxygen, and large effect of rain attenuation, which seriously affect the coverage performance of the high frequency communication system. In order to ensure that the high frequency communication and the long term evolution (LTE) system have similar SINR (Signal to Interference plus Noise Ratio) within a certain coverage range, it is necessary to guarantee the antenna gain of the high frequency communication. Fortunately, for the carrier frequency of the high frequency communication, the wavelength is short, so it is certain that more antenna elements can be accommodated per unit area. More antenna elements means that the coverage performance of the high frequency communication can be guaranteed by improving the antenna gain by using the beamforming method.

[0004] With the beamforming method, the transmitting end can concentrate the transmission energy in one direction, and the transmission energy in other directions is small or nonexistent. That is, each beam has its own directivity and can only cover terminals in a certain direction, and the transmitting end, i.e., the base station, needs to transmit multiple beams to achieve complete coverage. Generally, the number of beams ranges from tens to hundreds. To meet the access requirements of terminals in different directions, it is necessary to achieve omnidirectional coverage of the system broadcast message. The communication station must repeatedly transmit the same system broadcast message in different beam directions. In addition, the "absolute overhead" of the system broadcast message is large in the communication station.

[0005] In new radio (NR) communication systems, system information is a minimum system The minimum system information is further divided into minimum system information (SI) and other system information (OSI). The minimum system information is further divided into master information (MII) carried by the physical broadcast channel (PBCH). The MIB is divided into the master information block (MIB) and the remaining minimum system information (RMSI) carried by the physical downlink shared channel (PDSCH). The RMSI is carried by the PDSCH and scheduled by the corresponding physical downlink control channel (PDCCH). B is used to provide basic system parameters of the cell. The remaining minimum system information is used to provide configuration information related to initial access, such as the configuration for sending initial access requests and the configuration for receiving initial access response messages. Other system information that needs to be broadcast is called other system information. RMSI transmission is shown in Figure 1. FIG. 1 is a schematic diagram of RMSI transmission according to the related art of the present disclosure. Time division multiplexing between RMSI and a synchronization signal physical broadcast channel block (SS / PBCH block, SSB) is performed. Multiplexing or frequency division multiplexing is supported in the standard.

[0006] Regarding the time division multiplexing mode, FIG. 2 is a schematic diagram of the time division multiplexing transmission of RMSI according to the related art of the present disclosure. As shown in FIG. 2, during RMSI transmission, RMSI transmission may overlap with the transmission of a synchronization signal block, and the two may also be mapped to the same block. Regarding RMSI PDSCH reception, if the current standard specifies that the terminal receives PDSCH according to the instruction of RMSI PDCCH resource allocation, the PDSCH is not considered to include the resource of SSB transmission. This does not mean that the priority of RMSI transmission is higher than SSB transmission, but that there is a limitation for the base station to consider the resource occupied by SSB when the base station allocates RMSI source and avoids scheduling RMSI PDSCH on the resource occupied by SSB. Because the terminal does not know the actual transmission location information of SSB when receiving RMSI, if the RMSI resource overlaps with the SSB resource, the terminal cannot realize RMSI PDSCH reception based on rate matching according to the location of the SSB resource.

[0007] In the time domain resource allocation according to the related art, PDSCH is only supported for occupying several consecutive symbols in a slot. As for RMSI transmission, in view of the above details, the resource allocation of RMSI PDSCH is greatly restricted when SSB occupies the center symbol of a certain slot, and even RMSI PDSCH transmission cannot be realized in this particular slot. It can be seen that the time domain resource allocation according to the related art cannot be applied to RMSI.

[0008] In view of the problems of the related art described above, no effective solution has yet been proposed. Summary of the Invention [Means for solving the problem]

[0049] In this embodiment, the first subcarrier spacing (SCS) means an SCS corresponding to a first channel signal, where the first channel signal means a synchronization signal physical broadcast channel block (SSB), and the second SCS means an SCS corresponding to a second channel signal, where the second channel signal includes at least one of 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, a PDSCH carrying random access collision resolution information, a PDSCH carrying message 2 (MSG2), or a PDSCH carrying message 4 (MSG4).

[0053] Optionally, if the terminal correctly detects not only the downlink control information of the RMSI but also the RMSI but does not correctly detect the random access response information, the terminal detects the downlink control information of the RMSI in other slots among the multiple slots in the monitoring window.

[0054] From the description of the above embodiments, it is clear to those skilled in the art that the methods of the above embodiments can be realized by software and a necessary general-purpose hardware platform, or of course by hardware. However, in many cases, the former is a preferred implementation example. Based on this understanding, the solutions provided by the present disclosure can be substantially, or the part that contributes to the related art can be implemented in the form of a software product.

The second determination module is configured to determine a symbol occupied by a second channel signal according to a time domain resource allocation pattern in the time domain resource allocation pattern set.

[0058] This embodiment further provides a time domain resource detection apparatus, which includes a detection module, which is configured to detect downlink control information of a second channel signal in one or more slots in a monitoring window corresponding to the second channel signal.

[0059] In some embodiments, the various modules can be realized by software or hardware. The hardware realization can be, but is not necessarily, carried out in the following manner: the modules are arranged in the same processor, or the various modules are arranged in each processor in any combination.

[0060] EMBODIMENT 3 In the concept of this embodiment, the first channel signal is a synchronization signal physical broadcast channel block (SS / PBCH block, SSB). The mapping pattern of the SSB in the slot can be different according to the different subcarrier intervals. The mapping pattern includes the following cases:

[0061] Case A As shown in FIG. 5, FIG. 5 is a mapping pattern 1 of SSBs in a slot according to an embodiment of the present disclosure. The SSB mapping pattern shown in FIG. 5 corresponds to an SSB mapping pattern with a subcarrier spacing of 15 kHz. FIG. 5 shows the transmission resources of various SSBs. A 15 kHz slot (i.e., 14 symbols of 15 kHz, which are symbol 0 to symbol 13) contains two SSBs. Each of the two SSBs occupies four symbols of 15 kHz. The two SSBs are respectively symbol 2 to symbol 5 and and are mapped to symbols 8 to 11.

[0062] Case B As shown in FIG. 6, FIG. 6 is a mapping pattern 2 of SSBs in slots according to an embodiment of the present disclosure. The SSB mapping pattern shown in FIG. 6 corresponds to an SSB mapping pattern with a subcarrier spacing of 30 kHz. FIG. 6 shows the transmission resources of various SSBs. Two 30 kHz slots (i.e., 28 symbols of 30 kHz, which are two groups of symbols 0 to 13) include four SSBs. Each of the four SSBs occupies four symbols of 30 kHz. The four SSBs are respectively mapped to symbols 4 to 7 of the first slot, symbols 8 to 11 of the first slot, symbols 2 to 5 of the second slot, and symbols 6 to 9 of the second slot.

[0063] Case C As shown in FIG. 7, FIG. 7 is a mapping pattern 3 of SSBs in slots according to an embodiment. The SSB mapping pattern shown in FIG. 7 corresponds to an SSB mapping pattern with a subcarrier spacing of 30 kHz. FIG. 7 shows the transmission resources of various SSBs. Two 30 kHz slots (i.e., 28 symbols of 30 kHz, which are two groups of symbols 0 to 13) contain four SSBs. Each of the four SSBs occupies four symbols of 30 kHz. The four SSBs are respectively mapped to symbols 2 to 5 of the first slot, symbols 8 to 11 of the first slot, symbols 2 to 5 of the second slot, and symbols 8 to 11 of the second slot.

[0064] Case D As shown in FIG. 8, FIG. 8 is a mapping pattern 4 of SSBs in slots according to an embodiment of the present disclosure. The SSB mapping pattern shown in FIG. 8 corresponds to an SSB mapping pattern with a subcarrier spacing of 120 kHz. FIG. 8 shows the transmission resources of various SSBs. Two 120 kHz slots (i.e., 28 symbols of 120 kHz, which are two groups of symbols 0 to 13) contain four SSBs. Each of the four SSBs occupies four symbols of 120 kHz. The four SSBs are respectively mapped to symbols 4 to 7 of the first slot, symbols 8 to 11 of the first slot, symbols 2 to 5 of the second slot, and symbols 6 to 9 of the second slot.

[0065] Case E As shown in FIG. 9, FIG. 9 is a mapping pattern 5 of SSBs in a slot according to an embodiment of the present disclosure. The SSB mapping pattern shown in FIG. 9 corresponds to an SSB mapping pattern with a subcarrier spacing of 240 kHz. FIG. 9 shows the transmission resources of various SSBs. Two 120 kHz slots (i.e., 56 symbols of 240 kHz, which are symbols 0 to 55) contain 8 SSBs. Each of the 8 SSBs occupies 4 symbols of 240 kHz, which are numbered symbols in the above period (56 symbols). The 8 SSBs are mapped to symbols 8 to 11, symbols 12 to 15, symbols 16 to 19, symbols 20 to 23, symbols 32 to 35, symbols 36 to 39, symbols 40 to 43, and symbols 44 to 47, respectively.

[0066] The above description shows the case of symbol occupancy when an SSB is mapped to a slot with the same subcarrier spacing as the SSB. If an SSB is mapped to a slot with a different subcarrier spacing than the SSB, the absolute time position occupied by the SSB is It remains the same, but the indices of the occupied symbols may be transformed into the indices of the symbols in the target subcarrier spacing.

[0067] For example, as shown in Table 1, if a 15 kHz SSB is mapped to a 30 kHz slot, there will be two 30 kHz slots containing two SSBs, and these two SSBs occupy symbols 4 to 11 in the first 30 kHz slot and symbols 2 to 9 in the second 30 kHz slot.

[0068] [Table 1]

[0069] In the case of receiving RMSI, it can be considered that an SSB with a specific subcarrier spacing is mapped to a slot corresponding to the subcarrier spacing of the RMSI. In the following embodiments, the time domain allocation location is described for various combinations of SSB and RMSI subcarrier spacing.

[0070] Pattern 1 is for time division multiplexing between SSB and RMSI. The number and position of RMSI search space symbols for pattern 1, shown in Table 2, are described below. The RMSI search space is used to carry the RMSI PDCCH. The grey Dc represents the second search space position in the slot. Note: It is also possible to transmit only the PDCCH in the second search space in a slot (i.e., corresponding to configurations 13 to 19).

[0071] [Table 2]

[0072] This embodiment provides a time domain resource allocation method and system, which includes: allocating non-contiguous PDSCH time domain resources, determining RMSI time domain resource allocation lists for different subcarrier spacing combinations, determining time domain resource allocations according to slot SSB mapping positions, and supporting PDCCH to schedule PDSCH located in the previous symbol in the same slot.

[0073] This embodiment further includes implementation solutions to illustrate the concept of this embodiment in various combinations of SCS.

[0074] Implementation example 1: SCS{SSB,RMSI}={15,15}kHz For the subcarrier spacing (SCS) combination of {SSB, RMSI} = (15, 15} kHz, Table 3 shows the mapping position of SSB in the slot and the possible positions of the RMSI search space. Based on this, Table 3 further shows the time domain allocation pattern of RMSI PDSCH in the presence of some or all of the SSB.

[0075] [Table 3]

[0076] As shown in Table 4, Dc represents the symbol in which the RMSI search space is located in the slot. In view of search space position 1, 2, 4 or 10, search space positions 1, 2, 4 and 10 are considered as one class because the symbol position in search space position 1, 2, 4 or 10 does not exceed the second symbol. In view of search space position 3, 5 or 6, search space positions 3, 5 and 6 are considered as one class because the last symbol in search space positions 3, 5 and 6 is the third symbol. If a slot includes two search spaces, the second search space is represented in gray. In the table, SSB represents the symbol to which the SSB is mapped. Dd represents the symbol occupied by the PDSCH. If a slot includes two search spaces, the symbol occupied by the PDSCH and assigned to the PDCCH in the second search space is represented in gray.

[0077] [Table 4]

[0078] Table 5 shows possible time domain resource allocation patterns when the slot in which the RMSI is located does not contain an SSB.

[0079] [Table 5]

[0080] If the labels of the Dc and SSB symbols in Tables 4 and 5 are hidden and only the labels of the PDSCH symbols in Tables 4 and 5 (i.e., Dd) are left, each row of Tables 4 and 5 corresponds to a time domain resource allocation pattern. That is, the set of symbols labeled with Dd in each row is defined to be a time domain resource allocation pattern. By merging the same resource allocation patterns, the time domain resource allocation pattern set shown in Table 6 is obtained. That is, Table 6 shows the set of possible time domain resource allocation patterns when the SCS combination is {SSB, RMSI}={15, 15} kHz. There are 34 sets in total. Some sets may be selected from these 34 sets, and the time domain allocation may be indicated by a corresponding number of bits of the RMSI PDCCH. For example, 32 sets may be selected from the 34 time domain resource allocation pattern sets to serve as the default time domain resource allocation pattern set for RMSI, and thus the currently used time domain resource allocation pattern of the PDSCH is indicated by 5 bits to the terminal. As another example, in the standard, Therefore, 15 sets are selected from the 34 time domain resource allocation pattern sets and defined as the default time domain resource allocation pattern set for RMSI, and therefore the currently used time domain resource allocation pattern of PDSCH is indicated to the terminal by 4 bits, one of which is in reserved state.

[0081] [Table 6]

[0082] Regarding the indication of the time domain resource allocation pattern according to this embodiment, a specific first SCS (corresponding to SSB) and a second SCS (RMSI, OSI, paging, msg2 or msg4), the time domain resource allocation patterns where the slots include SSBs (Table 4) and the time domain resource allocation patterns where the slots do not include SSBs (Table 5) are combined into one time domain resource allocation pattern set. The currently used time domain resource allocation pattern in this set is indicated to the terminal by downlink control information (DCI) signaling. Various combinations of the first SCS and the second SCS may correspond to the same or different time domain resource allocation pattern sets of the second signal channel.

[0083] In some other implementation examples, multiple time domain resource allocation pattern sets may be defined for a combination of a first SCS and a second SCS (including a combination of one first SCS and one second SCS corresponding to multiple time domain resource allocation pattern sets, or multiple combinations of a first SCS and a second SCS corresponding to multiple time domain resource allocation pattern sets). First, the used time domain resource allocation pattern set is indicated to the terminal by DCI signaling. Next, the currently used time domain resource allocation pattern in the designated set is further indicated to the terminal by DCI signaling. For example, when two time domain resource allocation pattern sets are defined, one corresponds to the time domain resource allocation pattern when the slot includes an SSB (Table 4), and the other corresponds to the time domain resource allocation pattern when the slot does not include an SSB (Table 5). The currently used time domain resource allocation pattern set is indicated to the terminal by one bit of downlink control information (DCI), and the currently used time domain resource allocation pattern in the indicated time domain resource allocation pattern set is also indicated. In this case, the terminal determines at least one time domain resource allocation pattern set according to the obtained first SCS (which may correspond to a frequency band, and the terminal may determine the first SCS according to the current frequency band to which the first signal channel belongs; alternatively, the terminal determines the first SCS by blindly detecting the first channel signal, i.e., the terminal detects the first signal channel by using different SCSs and obtains the value of the first SCS according to whether the detection is successful or not) and the obtained second SCS (which may be an SCS notified by the base station, for example, the second SCS is notified in a physical broadcast channel; alternatively, the second SCS may be predetermined or may correspond to a frequency band), and determines the time domain resource allocation pattern set and a specific time domain resource allocation pattern according to an instruction of the DCI.

[0084] For the time domain allocation pattern when a slot does not contain SSB, it can also be indicated by the existing indication method of time domain resource allocation. That is, the currently used time domain resource allocation is indicated by the parameter "start and length indicator (SLIV)". Each SLIV index corresponds to a symbol allocation scheme that can uniquely indicate the start symbol of the allocated symbols and the number of allocated symbols. For the time domain resource allocation pattern when a slot contains SSB, the currently used time domain resource allocation may be indicated by listing the time domain resource allocation pattern in a table together with DCI signaling.

[0085] In some other implementation examples, the currently used time domain resource allocation pattern set may be indicated not by the information bits of the downlink control information, but by defining a correspondence between the slot type and the time domain resource allocation pattern set. For example, the slots may be divided into two classes: slots containing the transmission resources of the first channel signal (SSB) and slots containing the transmission resources of the first channel signal (SSB). In this case, for a slot including a transmission resource of the first channel signal (SSB), the terminal determines a "time domain resource allocation pattern when the slot includes an SSB (Table 4)" and sets this as a currently used time domain resource allocation pattern set, and for a slot not including a transmission resource of the first channel signal (SSB), the terminal determines a "time domain resource allocation pattern when the slot does not include an SSB (Table 5)" and sets this as a time domain resource allocation pattern set. Furthermore, the base station indicates the currently used time domain resource allocation pattern to the terminal by downlink control information.

[0086] Specifically, for a specific combination of the first SCS and the second SCS, define multiple time domain resource allocation pattern sets. Furthermore, the terminal determines a currently used time domain resource allocation pattern set of a slot according to a current slot type.

[0087] Since a terminal does not know whether an SSB is actually being transmitted in a particular slot that includes an SSB transmission resource, this specification uses "whether a transmission resource for a first channel signal (SSB) is included" as the basis for distinguishing slot types, rather than "whether a first channel signal (SSB) is included."

[0088] In some other embodiments, the currently used time domain resource allocation pattern set may be indicated only by DCI signaling, i.e. the domain resource allocation pattern set is not related to the combination of SCSs, but rather a number of defined time domain resource allocation pattern sets may be applied to all combinations of the first SCS and the second SCS, and the currently used time domain resource allocation pattern set is only signaled by signaling.

[0089] In some other embodiments, the currently used time domain resource allocation pattern set may be determined according to the slot type only, i.e., the time domain resource allocation pattern set is not related to the SCS combination and is not signaled by signaling.

[0090] In some other embodiments, the time domain resource allocation pattern set may be determined by slot type and DCI signaling, i.e., multiple time domain resource allocation pattern sets are determined by slot type, and the currently used time domain resource allocation pattern set is signaled by DCI signaling. Alternatively, a group of time domain resource allocation pattern sets is indicated by DCI signaling, and the UE determines the currently used time domain resource allocation pattern set according to the slot type.

[0091] In some other implementations, the time domain resource allocation pattern set may be determined by a combination of the SCS, slot type, and DCI signaling.

[0092] Note: Regardless of which indication manner is used to determine the time domain resource allocation pattern set, the correspondence between the indication manner and the time domain resource allocation pattern set needs to be predefined. In some embodiments, the predefined one may be specified in a protocol.

[0093] Note: the DCI signaling may be signaling carried on other carriers, for example radio resource control (RRC) signaling carried on other carriers.

[0094] The above description can also be used for other implementations. Implementation example 2: SCS{SSB,RMSI}={15,30}kHz For the subcarrier spacing (SCS) combination of {SSB, RMSI}={15, 30} kHz, Table 7 shows the mapping position of SSB in a slot and the possible position of RMSI search space (i.e., Dc represents the symbol where RMSI search space is located in a slot). Based on this, the time domain allocation pattern of RMSI PDSCH when there are some or all of SSBs is further given. In this embodiment, in view of space positions 1, 2, 4 or 10, the search space positions 1, 2, 4 and 10 are considered as one class, since the symbol position does not exceed the second symbol. In view of the last symbol of search space positions 3, 5 or 6 being the third symbol, the search space positions 3, 5 and 6 are considered as one class. When a slot contains two search spaces, the second search space is represented in grey. SSB represents the symbol where SSB is mapped. Dd represents the symbol occupied by PDSCH. If a slot contains two search spaces, the symbols occupied by the PDSCH and assigned the PDCCH in the second search space are shown in grey.

[0095] [Table 7]

[0096] See Table 5 for possible time domain resource allocation patterns when the slot in which the RMSI is located does not contain an SSB.

[0097] If the labels of Dc and SSB symbols in Tables 7 and 5 are hidden and only the label of PDSCH symbols (i.e., Dd) in Tables 7 and 5 is left, each row of Tables 7 and 5 corresponds to a time domain resource allocation pattern. That is, the set of symbols labeled with Dd in each row is defined to be a time domain resource allocation pattern. By merging the same resource allocation patterns, the time domain resource allocation table shown in Table 8 is obtained. Table 8 shows the possible time domain resource allocation schemes when the SCS combination is {SSB, RMSI}={15, 30} kHz. There are a total of 28 schemes. Some of these 28 schemes may be selected, and the time domain allocation may be indicated by a corresponding number of bits in the RMSI PDCCH. For example, the currently used time domain resource allocation of the PDSCH is indicated to the terminal by 4 bits, and there are 4 reserved states. As another example, in order to reduce the bit overhead of the time domain resource allocation, the standard defines that 16 of the 28 time domain resource allocation schemes are the default time domain resource allocation pattern schemes of the RMSI, and therefore the currently used time domain resource allocation pattern of the PDSCH is indicated to the terminal by 4 bits.

[0098] [Table 8]

[0099] Implementation example 3: SCS{SSB,RMSI}={30,15}kHz For the subcarrier spacing (SCS) combination of {SSB, RMSI} = {30, 15} kHz, Table 9 shows the mapping of SSB mapping pattern 1 in the slot. In Table 9, the search positions and possible positions of the RMSI search space are shown (i.e., Dc denotes the symbol in the slot where the RMSI search space is located). Based on this, Table 9 shows the time domain allocation pattern of the RMSI PDSCH when there are some or all of the SSBs. See Table 3 for the index of the search space positions. Considering the space positions 1, 2, 4 or 10, the search space positions 1, 2, 4 and 10 are considered as one class since the symbol position does not exceed the second symbol. Considering that the last symbol in the search space positions 3, 5 or 6 is the third symbol, the search space positions 3, 5 and 6 are considered as one class. If a slot contains two search spaces, the second search space is shown in grey. SSB denotes the symbol to which the SSB is mapped. Dd denotes the symbol occupied by the PDSCH. If a slot contains two search spaces, the symbol occupied by the PDSCH and assigned to the PDCCH in the second search space is shown in grey.

[0100] [Table 9]

[0101] TIFF0007663661000010.tif142161

[0102] Table 10 shows the mapping positions of SSB mapping pattern 1 in a slot and the possible positions of the RMSI search space (i.e., Dc represents the symbol in which the RMSI search space is located in a slot). Based on this, the time domain allocation patterns of the RMSI PDSCH in the presence of some or all of the SSBs are further given.

[0103] When SSB0 is actually transmitted, search space location 1 is equivalent to search space location 3 with no SSB, which is not specifically shown in Table 10.

[0104] [Table 10]

[0105] See Table 5 for possible time domain resource allocation patterns when the slot in which the RMSI is located does not contain an SSB.

[0106] If the labels of Dc and SSB symbols in Table 10, Table 9, and Table 5 are hidden and only the labels of PDSCH symbols (i.e., Dd) in Table 10, Table 9, and Table 5 are left, each row of Table 9, Table 10, and Table 5 corresponds to a time domain resource allocation pattern. That is, the set of symbols labeled with Dd in each row is defined as a time domain resource allocation pattern. By merging the same resource allocation patterns, the time domain resource allocation table shown in Table 11 is obtained. Table 11 shows possible time domain resource allocation schemes when the SCS combination is {SSB, RMSI}={30, 15} kHz. There are 62 schemes in total. Some schemes may be selected from these 62 schemes, and the time domain allocation may be indicated by the corresponding number of bits of the RMSI PDCCH. For example, in the standard, the currently used time domain resource allocation pattern of PDSCH is indicated by 6 bits to the terminal, and there are two reserved states. As another example, in order to reduce the bit overhead of time domain resource allocation, the standard defines 16 of 62 time domain resource allocation schemes as the default time domain resource allocation pattern scheme for RMSI, and therefore the currently used time domain resource allocation pattern of PDSCH is indicated to the terminal by 4 bits.

[0107] In addition, Table 11 shows a generic set of time domain resource allocations for RMSI PDSCH for subcarrier spacing combination {SSB, RMSI}={30, 15} kHz. Alternatively, the time domain resource allocation table for RMSI PDSCH can be defined for each different mapping pattern of 30 kHz SSB (i.e., Pattern 1 and Pattern 2) to reduce the indication overhead.

[0108] In addition, define separate resource allocation tables for different search space types, for example, define different time domain resource allocation tables according to the following cases: when a slot includes only one search space, when a slot includes two search spaces and the PDCCH is included in the first search space of the two search spaces, and when a slot includes two search spaces and the PDCCH is included in the second search space of the two search spaces.

[0109] [Table 11]

[0110] TIFF0007663661000013.tif119150

[0111] Implementation example 4: SCS{SSB,RMSI}={30,30}kHz For the subcarrier spacing (SCS) combination of {SSB, RMSI}={30, 30} kHz, Tables 12 and 13 show the mapping positions of SSB mapping pattern 1 in a slot and the possible positions of the RMSI search space (i.e., Dc represents the symbol in the slot where the RMSI search space is located). Based on this, the time domain allocation patterns of the RMSI PDSCH in the presence of some or all of the SSBs are further given. Please refer to Table 3 for the index of the search space positions. Considering the space positions 1, 2, 4 or 10, the search space positions 1, 2, 4 and 10 are considered as one class, since the symbol position does not exceed the second symbol. Considering the last symbol of the search space positions 3, 5 or 6 is the third symbol, the search space positions 3, 5 and 6 are considered as one class. If a slot contains two search spaces, the second search space is represented in grey. SSB represents the symbol where the SSB is mapped. Dd denotes a symbol occupied by a PDSCH. When a slot includes two search spaces, the symbol occupied by a PDSCH in the second search space and assigned with a PDCCH is indicated in gray.

[0112] [Table 12]

[0113] [Table 13]

[0114] See Table 5 for possible time domain resource allocation patterns when the slot in which the RMSI is located does not contain an SSB.

[0115] If the labels of Dc and SSB symbols in Tables 12, 13, and 5 are hidden and only the labels of PDSCH symbols (i.e., Dd) in Tables 12, 13, and 5 are left, each row of Tables 12, 13, and 5 corresponds to a time domain resource allocation pattern. That is, the set of symbols labeled with Dd in each row is defined as a time domain resource allocation pattern. By merging the same resource allocation patterns, the time domain resource allocation table shown in Table 14 is obtained. When the SCS combination is {SSB, RMSI}={30, 30} kHz, there are a total of 53 possible time domain resource allocation schemes. Some schemes may be selected from these 53 schemes, and the time domain allocation may be indicated by the corresponding number of bits of the RMSI PDCCH. For example, in the standard, the currently used time domain resource allocation pattern set of PDSCH is indicated by 6 bits to the terminal, and there are 11 reserved states. As another example, in order to reduce the bit overhead of time domain resource allocation, the standard defines 16 of the 53 time domain resource allocation schemes as the default time domain resource allocation scheme for RMSI, and therefore the currently used time domain resource allocation pattern of PDSCH is indicated to the terminal by 4 bits.

[0116] In implementation example 1 of 30 kHz SSB pattern 2, the time domain resource allocation is the same as when the subcarrier spacing combination is {SSB, RMSI} = {15, 15} kHz. Table 6 may again be used as a generic set of time domain resource allocation configurations for 30 kHz SSB pattern 2.

[0117] [Table 14]

[0119] Implementation example 5: SCS{SSB,RMSI}={120,60}kHz For the subcarrier spacing (SCS) combination of {SSB, RMSI}={120, 60} kHz, Table 15 shows the mapping position of the SSB in the slot and the possible positions of the RMSI search space (i.e., Dc represents the symbol in the slot where the RMSI search space is located). Based on this, the time domain allocation pattern of the RMSI PDSCH in the presence of some or all of the SSBs is further given. Considering the space positions 1, 2, 4 or 10, the search space positions 1, 2, 4 and 10 are considered as one class, since the symbol position does not exceed the second symbol. Considering the last symbol of the search space positions 3, 5 or 6 is the third symbol, the search space positions 3, 5 and 6 are considered as one class. If the slot contains two search spaces, the second search space is represented in grey. SSB represents the symbol where the SSB is mapped. Dd represents the symbol occupied by the PDSCH. If a slot contains two search spaces, the symbols occupied by the PDSCH and assigned the PDCCH in the second search space are shown in grey.

[0120] The time domain resource allocation in search space positions 1-9 in Table 15 is identical to 30 kHz SSB mapping pattern 1 in implementation example 3 and will not be repeated here.

[0121] [Table 15]

[0122] TIFF0007663661000019.tif127157

[0123] See Table 5 for possible time domain resource allocation patterns when the slot in which the RMSI is located does not contain an SSB.

[0124] If the labels of Dc and SSB symbols in Tables 15 and 5 are hidden and only the labels of PDSCH symbols (i.e., Dd) in Tables 15 and 5 are left, each row of Tables 15 and 5 corresponds to a time domain resource allocation pattern. That is, the set of symbols labeled with Dd in each row is defined to be a time domain resource allocation pattern. By merging the same resource allocation patterns, a time domain resource allocation table shown in Table 16 is obtained. When the SCS combination is {SSB, RMSI}={30, 30} kHz, there are a total of 54 possible time domain resource allocation schemes. In addition, the time domain resource allocation in search space positions 1-9 is the same as the 30 kHz SSB mapping pattern 1 in implementation example 3. The above 54 schemes and the resource allocation corresponding to the above search space in Table 11 are combined as a generic set of time domain resource allocation. Some time domain resource allocation schemes may be selected from this generic set, and the time domain allocation is indicated by a corresponding number of bits of the RMSI PDCCH. For example, in the standard, the currently used time domain resource allocation of PDSCH is indicated to the terminal by 6 bits, and there are 11 reserved states. As another example, in order to reduce the bit overhead of time domain resource allocation, the standard defines that 16 of some time domain resource allocation schemes are the default time domain resource allocation schemes of RMSI, and therefore the currently used time domain resource allocation pattern of PDSCH is indicated to the terminal by 4 bits.

[0125] [Table 16]

[0126] TIFF0007663661000021.tif71158

[0127] Implementation example 6: SCS{SSB,RMSI}={120,120}kHz For the subcarrier spacing (SCS) combination of {SSB, RMSI}={120, 120} kHz, Table 17 shows the mapping position of SSB in a slot and the possible position of RMSI search space (i.e., Dc represents the symbol where RMSI search space is located in a slot). Based on this, the time domain allocation pattern of RMSI PDSCH in the presence of some or all of SSB is further given. In this embodiment, the situation of search space position {1, 2, 4, 5, 7, 8} is the same as the resource allocation situation of the corresponding search space in Table 12 and Table 13, and is not repeated here.

[0128] If a slot contains two search spaces, the second of these two search spaces is shown in grey. SSB denotes the symbol to which the SSB is mapped. Dd denotes the symbol occupied by the PDSCH. If a slot contains two search spaces, the symbol in the second search space occupied by the PDSCH and assigned with the PDCCH is shown in grey.

[0129] [Table 17]

[0130] See Table 5 for possible time domain resource allocation patterns when the slot in which the RMSI is located does not contain an SSB.

[0131] If the labels of Dc and SSB symbols in Tables 17 and 5 are hidden and only the labels of PDSCH symbols (i.e., Dd) in Tables 17 and 5 are left, each row of Tables 17 and 5 corresponds to a time domain resource allocation pattern. That is, the set of symbols labeled with Dd in each row is defined as a time domain resource allocation pattern. By merging the same resource allocation patterns, a time domain resource allocation table shown in Table 18 is obtained. When the SCS combination is {SSB, RMSI}={120, 120} kHz, there are a total of 31 possible time domain resource allocation schemes. In addition, for the search space allocation {1, 2, 4, 5, 7, 8}, the above 31 possible time domain resource allocation schemes and the corresponding search space resource allocation situations in Tables 12 and 13 are combined into a generic set of time domain resource allocations. Some time domain resource allocation schemes may be selected from this generic set, and the time domain allocation is indicated by a corresponding number of bits of the RMSI PDCCH. For example, in the standard, the currently used time domain resource allocation of PDSCH is indicated to the terminal by 6 bits, and there are 10 reserved states. As another example, in order to reduce the bit overhead of time domain resource allocation, the standard defines that 16 schemes of the generic set of time domain resource allocation are the default time domain resource allocation schemes of RMSI, and therefore the currently used time domain resource allocation pattern of PDSCH is indicated to the terminal by 4 bits.

[0132] [Table 18]

[0133] Implementation example 7: SCS{SSB,RMSI}={240,60}kHz For the subcarrier spacing (SCS) combination of {SSB, RMSI}={240, 60} kHz, Table 19 shows the mapping position of the SSB in the slot and the possible positions of the RMSI search space (i.e., Dc represents the symbol in the slot where the RMSI search space is located). Based on this, Table 19 shows the time domain allocation pattern of the RMSI PDSCH in the presence of some or all of the SSB.

[0134] In this case, the RMSI slot contains eight SSBs. To simplify the number of possible time domain allocation patterns, we assume that the actual transmission status of four consecutive SSBs (i.e., SSB0-3, or SSB4-7) is the same. When SSB is actually transmitted, all of SSB0-3 are considered to be transmitted when the base station allocates time domain resources for RMSI PDSCH. The same applies to SSB4-7. Different time domain allocation patterns are given as shown in Table 19. If a slot contains two search spaces, the second of the two search spaces is represented in grey. SSB represents the symbol to which SSB is mapped. Dd represents the symbol occupied by PDSCH. If a slot contains two search spaces, the symbol occupied by PDSCH and allocated PDCCH in the second search space is represented in grey.

[0135] [Table 19]

[0136] If we hide the labels of Dc and SSB symbols in Tables 19 and 5 and leave only the labels of PDSCH symbols (i.e., Dd) in Tables 19 and 5, each row of Tables 19 and 5 corresponds to a time domain resource allocation pattern. That is, the set of symbols labeled with Dd in each row is defined to be a time domain resource allocation pattern. By merging identical resource allocation patterns, we obtain the time domain resource allocation table shown in Table 20. For the SCS combination of {SSB, RMSI}={240, 60} kHz, there are a total of 32 possible time domain resource allocation schemes that serve as a generic set of time domain resource allocations. From this generic set, several The time domain resource allocation scheme of the RMSI PDCCH may be selected, and the time domain allocation may be indicated by a corresponding number of bits of the RMSI PDCCH. For example, in the standard, the currently used time domain resource allocation of the PDSCH is indicated to the terminal by 5 bits, and the corresponding relationship between various time domain resource allocation schemes and the value of the indication bit is defined. As another example, in order to reduce the bit overhead of the time domain resource allocation, the standard defines 16 of the 32 time domain resource allocation schemes as the default time domain resource allocation pattern scheme of the RMSI, and the corresponding relationship between various time domain resource allocation schemes and the value of the indication bit is defined, and therefore the currently used time domain resource allocation pattern of the PDSCH is indicated to the terminal by 4 bits.

[0137] [Table 20]

[0138] Implementation example 8: SCS{SSB,RMSI}={240,120}kHz For the subcarrier spacing (SCS) combination of {SSB, RMSI}={240, 120} kHz, Table 21 shows the mapping positions of SSB in a slot and possible positions of RMSI search space (i.e., Dc represents the symbol where RMSI search space is located in a slot). Based on this, the time domain allocation pattern of RMSI PDSCH in the presence of some or all of SSBs is further given.

[0139] If a slot contains two search spaces, the second of these two search spaces is used. In the figure, the search space is shown in gray. SSB indicates the symbol to which the SSB is mapped. Dd indicates the symbol occupied by the PDSCH. If a slot contains two search spaces, the symbol occupied by the PDSCH in the second search space and assigned with the PDCCH is shown in gray.

[0140] [Table 21]

[0141] TIFF0007663661000027.tif104165

[0142] If the labels of Dc and SSB symbols in Tables 21 and 5 are hidden and only the labels of PDSCH symbols (i.e., Dd) in Tables 21 and 5 are left, each row of Tables 21 and 5 corresponds to a time domain resource allocation pattern. That is, the set of symbols labeled with Dd in each row is defined as a time domain resource allocation pattern. By merging the same resource allocation patterns, a time domain resource allocation table shown in Table 22 is obtained. When the SCS combination is {SSB, RMSI}={240, 120} kHz, there are a total of 39 possible time domain resource allocation schemes, which serve as a generic set of time domain resource allocations. Some time domain resource allocation schemes may be selected from this generic set, and the time domain allocation patterns are indicated by a corresponding number of bits in the RMSI PDCCH. For example, in the standard, the currently used time domain resource allocation of PDSCH is indicated to the terminal by 5 bits. 32 time domain resource allocation schemes are selected from the 39 time domain resource allocation schemes, and the correspondence between various time domain resource allocation schemes and the value of the indication bit is determined. As another example, in order to reduce the bit overhead of time domain resource allocation, the standard defines 16 of the 39 time domain resource allocation schemes as the default time domain resource allocation scheme for RMSI, and determines the value of the indication bit, so that the currently used time domain resource allocation pattern of PDSCH is indicated to the terminal by 4 bits.

[0143] [Table 22]

[0144] Implementation example 9 One or more physical downlink control channel monitoring windows (PDCCH monitoring windows) are configured at the network side for transmitting the second signaling channel and the downlink control information corresponding to the second signaling channel. Different monitoring windows are associated with different SSBs. A terminal determines a position of a monitoring window corresponding to the SSB in response to receiving the SSB, and carries a second channel signal. The second channel signal includes at least one of 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, a PDSCH carrying random access collision resolution information, a PDSCH carrying MSG2, or a PDSCH carrying MSG4.

[0145] The terminal detects downlink control information (DCI) corresponding to the second channel signal in the configured monitoring window according to the search space configuration. The monitoring window includes one or more slots. When the monitoring window includes multiple slots, different monitoring windows may overlap. In this case, the monitoring window may include multiple second channel signals (corresponding to different SSBs). The terminal detects the second channel signal having a quasi-co-location (QCL) relationship with the SSB detected by the terminal. The channel signal of the SSB has a higher detection performance, but the second channel signal corresponding to the other SSB is the one that the terminal can detect first in the monitoring window. Even if the reception is successful, the access is not successful. Therefore, it cannot be considered that only one second channel signal is transmitted in multiple slots in one monitoring window for the terminal. That is, the terminal needs to detect the downlink control information of the second channel signal in one or more slots in the monitoring window corresponding to the second channel signal.

[0146] Specifically, in the following cases in the following process, the terminal needs to continue to detect the downlink control information of the second channel signal in other slots within the monitoring window.

[0147] Sub-Example 1 If the terminal correctly detects the downlink control information of the second channel signal in a particular slot in the monitoring window but does not correctly detect the second channel signal, the downlink control information of the second channel signal correctly detected by the terminal may not be a transmission in the beam direction or on the downlink port to which the terminal belongs (i.e., the successfully received downlink control information does not have a quasi-collocation (QCL) relationship with the SSB previously detected by the terminal, but is only successfully received by the terminal because the monitoring windows overlap). 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.

[0148] Sub-Example 2 If the terminal correctly detects not only the downlink control information of the RMSI but also the RMSI, and performs preamble transmission according to the random access configuration in the RMSI, but fails to correctly detect the random access response information, the possible reason in this case is that the RMSI received by the terminal does not have a quasi-collocation (QCL) relationship with the SSB previously detected by the terminal. That is, the received RMSI is not the target RMSI that the terminal should receive, and the random access request (preamble) transmitted according to the configuration in the detected RMSI is incorrect, so the base station does not return the corresponding random access response information. Therefore, the terminal continues to detect the downlink control information of the RMSI in other slots in the monitoring window corresponding to the first channel signal, and performs a new reception. The next random access request and receiving configuration are determined based on the received signal.

[0149] In the present application, the features of the various embodiments may be used in combination with each other in one embodiment unless there is a conflict, and each embodiment is merely a best mode for implementing the present application.

[0150] The embodiments provide a time domain resource allocation method and system. A time domain resource allocation solution that does not conflict with synchronization signal block transmission resources is obtained in view of the mapping patterns from synchronization signal blocks to slots in various subcarrier spacing combinations.

[0151] The solution of this embodiment avoids the restriction of resource allocation to RMSI PDSCH caused by the existing time domain resource allocation mode in which PDSCH is only supported for occupying a few consecutive symbols in a slot, thereby improving the efficiency and flexibility of resource allocation. In addition, a time domain resource allocation list is defined for different combinations of subcarrier intervals, which greatly reduces the overhead of time domain resource allocation and effectively supports the time domain resource allocation of RMSI PDSCH.
