[0027] This disclosure provides an information processing method, a communication device, a communication system, and a storage medium.

[0028] In a first aspect, embodiments of this disclosure propose an information processing method, executed by a base station, comprising: sending a DCI in a first SI window, wherein the DCI is used to schedule multiple PDSCHs; and the multiple PDSCHs are used to carry multiple SIs.

[0029] In the above embodiments, a DCI can be sent in a first SI window so that the DCI can schedule multiple PDSCHs carrying SIs, that is, multiple SIs can be sent in one SI window; this allows the terminal to blindly detect multiple SIs in one SI window, which can reduce blind detection of SIs and facilitate energy saving for the base station and the terminal.

[0030] In conjunction with some embodiments of the first aspect, in some embodiments, the first information field of the DCI is used to indicate the time-domain resources of a plurality of PDSCHs; or, the first information field of the DCI is used to indicate an entry in a first table, wherein an entry is used to indicate the time-domain resources of at least one PDSCH.

[0031] In the above embodiments, the time domain resources of multiple PDSCHs can be indicated by one information field of DCI, or by one entry in a table, thereby realizing the scheduling of PDSCHs of multiple bearer SIs by DCI based on one SI window, and realizing energy saving of base stations and terminals.

[0032] In conjunction with some embodiments of the first aspect, in some embodiments, the first table is agreed upon by the protocol, or the first table is configured by the base station.

[0033] In the above embodiments, the first table (i.e., the time-domain resource allocation table for PDSCH) can be determined in a variety of ways, which can adapt to more application scenarios.

[0034] In conjunction with some embodiments of the first aspect, in some embodiments, an entry is used to indicate at least one of the following for at least one PDSCH: a first symbol position, the first symbol position being the time-domain start symbol position of the PDSCH; a second symbol position, the second symbol position being the time-domain end symbol position of the PDSCH; a first time-domain length, the first time-domain length being the time-domain symbol length of the PDSCH; a first time-domain interval, the first time-domain interval being the time-domain interval between the time-domain unit of the PDSCH and the time-domain unit of the scheduled DCI; a time-domain resource position, the time-domain resource position being used to indicate the relative time-domain position of the Demodulation Reference Signal (DMRS) in the PDSCH; and resource mapping information, the resource mapping information being used to indicate the resource mapping method of the PDSCH.

[0035] In the above embodiments, time-domain resource indication for at least one PDSCH of an entry can be achieved using fewer bits in the DCI, which can save bit resources in the DCI so that the DCI can have more remaining bits to implement other functions.

[0036] In conjunction with some embodiments of the first aspect, in some embodiments, the first SI window is one of the following: any SI window among the SI windows of the multiple scheduled SIs; or the SI window with the smallest index value among the SI windows of the multiple scheduled SIs.

The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0094] In some embodiments, the core network equipment may be a single device, multiple devices, or a group of devices. Network functions may be virtual or physical. The core network includes, for example, at least one of the following: Evolved Packet Core (EPC), 5G Core Network (5GCN), Next Generation Core (NGC), and 6G Core Network (6GCN).

[0095] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions provided in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in this disclosure are also applicable to similar technical problems.

[0096] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1A, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1A are illustrative. The communication system may include all or some of the main bodies in FIG1A, or it may include other main bodies outside of FIG1A.

[0098] In some embodiments, when a User Equipment (UE) powers on, the UE acquires System Information (SI) for cell selection and / or cell reselection. System Information may include at least one of the following: a Master Information Block (MIB) and a System Information Block (SIB); wherein the MIB and SIB Type 1 (i.e., SIB1) are two important pieces of system information required for the UE to select and / or lock onto a cell. The MIB and SIB are referred to as Minimum System Information (MSI). Standalone SIB1 is referred to as Remaining Minimum System Information (RMSI). Other system information, such as from SIB2 to subsequent SIBn (e.g., n=12, etc.), is referred to as Other System Information (OSI). SIB1 is periodically broadcast via the Downlink Shared Channel (DL-SCH) or transmitted via unicast over the DL-SCH. Other system information (such as SIB2 to SIBn) can be broadcast periodically via DL-SCH, broadcast on demand via DL-SCH, or transmitted via DL-SCH in a unicast manner.

[0099] SIB1 contains scheduling information for all system information messages. SIBs with the same period can be mapped to the same system information. The scheduling information includes the SI window length (in units of time slots; all scheduled SIs have the same SI window length), each SI has its own transmission period (e.g., 8, 16, 32, or 64 radio frames, a radio frame can be 10 milliseconds (ms), etc.), and the configuration of one or more SIBs contained in each SI. Each SIB has its own corresponding SI window. Within a specific search space within the SI window, the base station uses DCI to schedule the SIs corresponding to that SI window (the search space of DCI for transmission scheduling OSI is the search space for all specific search spaces). The SI windows corresponding to each SI do not overlap in the time domain. That is, only one SI can be scheduled within an SI window, and multiple SIs cannot be scheduled.

[0100] In some embodiments, the SI window mechanism corresponding to an SI is determined as follows: the starting slot#a of the SI window corresponding to SI n is as follows: a = x mod N; the SFN it belongs to is as follows: SFN mod T = FLOOR(x / N); where n is the order of one or more SIs included in the above SI scheduling information; N is the number of slots contained in a radio frame; T is the period of SI n. x = (n-1) × w, where w is the SI window length. SFN is the system frame number, also known as the radio frame number or frame number.

[0101] In some embodiments, the base station sends a DCI that schedules an SI within the SI window, and the DCI schedules a PDSCH; the PDSCH carries information about a scheduled SI.

[0102] For example, consider the following scenario where each SI message contains one or more SIBs. As shown in Table 1 below, the SI of the first entry in the schedulingInfoList of SIB1 is SIB2, the SIs of the second entry are SIB3 and SIB4, the SI of the third entry is SIB5, and the SI of the fourth entry is SIB6. The subcarrier spacing is 30 kHz, and the number of time slots in a radio frame is 20. The SI window length is 20 time slots, and different SIs have different periodicities.

[0103] Table 1

[0104] For example, the transmission methods of the four SIs shown in Table 1 can be as shown in Figure 1B, wherein SI1 can be transmitted in radio frames 0, 8, 16, 24, 32, 40, 48 and 56; SI2 can be transmitted in radio frames 1, 9, 17, 25, 33, 49 and 57; SI3 can be transmitted in radio frames 2, 18, 34 and 50; and SI4 can be transmitted in radio frames 3 and 35.

[0105] In some embodiments, the UE can be a terminal, or the terminal can be a UE.

[0106] Figure 2A is an interactive schematic diagram illustrating an information processing method according to an embodiment of the present disclosure. As shown in Figure 2A, this embodiment of the present disclosure relates to an information processing method used in a communication system 100, the method comprising:

[0107] In step S2101, the base station sends DCI to the terminal in the first SI window.

[0108] In some embodiments, the terminal receives DCI sent by the base station in the first SI window.

[0109] Optionally, the base station may send DCI to the terminal within a first SI window. Correspondingly, the base station may receive DCI within a first SI window.

[0110] Optionally, DCI is used to schedule multiple PDCSHs; multiple PDSCHs are used to carry SIs.

[0111] For example, one DCI can be used to schedule multiple PDSCHs. In embodiments of this disclosure, the multiple can be two or more.

[0112] For example, multiple PDSCHs used to carry SIs may include at least one of the following: one PDSCH used to carry one SI, and one PDSCH used to carry multiple SIs. Here, when one DCI is used to schedule multiple PDSCHs and one PDSCH is used to carry one or more SIs, the base station can send multiple SIs through one DCI, so that the terminal can blindly detect the DCI in the first SI window, which can reduce blind detection of PDSCHs, etc., and is beneficial to energy saving for both the base station and the terminal.

[0113] For example, the DCI can be any type of DCI.

[0114] For example, the DCI can be a pre-defined DCI used to schedule SIs. For example, the DCI can be a DCI scrambled with the System Information Radio Network Temporary Identity (SI-RNTI). Thus, if the terminal retrieves the SI-RNTI's DCI, it determines that the base station is scheduling a system message.

[0115] Optionally, the first SI can be one of the following: any SI window among the multiple scheduled SIs, and the SI window with the smallest index value among the multiple scheduled SIs.

[0116] For example, the scheduled SIs can be two or more.

[0117] For example, there are four scheduled SIs: SI1, SI2, SI3, and SI4. The SI windows corresponding to SI1, SI2, SI3, and SI4 are SI window 1, SI window 2, SI window 3, and SI window 4, respectively. DCI can be sent in any one of these SI windows, or in the SI window with the smallest index value (e.g., SI window 1). As shown in Figure 2B, SI windows 1, SI2, SI3, and SI4 can be radio frames (or frames) with sequence numbers 0, 1, 2, and 3, respectively. Therefore, DCI can be sent in radio frames with sequence numbers 0, 1, 2, 3, or 4.

[0118] Optionally, the scheduled SIs may be adjacent in the time domain or consecutive in the time domain. For example, as shown in Figure 1B, the scheduled SI1, SI2, SI3, and SI4 may be adjacent or consecutive in the time domain.

[0119] Optionally, the scheduled SIs can also be discontinuous in the time domain. For example, the scheduled SI1, SI2, SI3, and SI4 can be on radio frames 0, 2, 4, and 6, respectively; thus, the scheduled SI1, SI2, SI3, and SI4 can be discontinuous in the time domain.

[0120] Optionally, the period of the SI window for the multiple scheduled SIs is a multiple of the first value. For example, the period of each SI window for the multiple scheduled SIs is a multiple of the first value.

[0121] For example, SIs are periodic; such as base stations periodically broadcasting SIs or scheduling SIs once every SI period. For instance, if an SI has a period of 8 frames, it can be scheduled in frame 0, frame 8, frame 16, ..., frame 8×n, where n is an integer greater than or equal to 0. Correspondingly, the SI window of an SI is also periodic; for example, if the SI window period of an SI is 8 frames, DCIs will be sent in frame 0, frame 8, frame 16, ..., frame 8×n to schedule the SI. The period of the SI window can be different or the same for different SIs. In this embodiment, the serial numbers of radio frames (or frames), time slots, and symbols can all start from 0, for example, radio frame 0, radio frame 1, time slot 0, time slot 1, symbol 0, symbol 1, etc.; in other embodiments, the serial numbers of radio frames (or frames), time slots, and symbols can all start from 1, for example, radio frame 1, radio frame 2, time slot 1, time slot 2, symbol 1, symbol 2, etc. The serial numbers of radio frames (or frames), time slots, and symbols can all start from 0.

[0122] For example, SI is transmitted within the SI window. If SI is periodic, then SI will be transmitted periodically within the SI window; the periodicity of the SI window can be represented by the period of the SI window.

[0123] For example, the first value can be any value.

[0124] For example, the first value can be the minimum period of the SI window of the scheduled SIs. For instance, as shown in Table 1 and Figure 1B, the periods of the SI windows of the scheduled SIs 1, SI 2, SI 3 and SI 4 can be 8, 8, 16 and 32 radio frames (or frames), respectively; the minimum period of the SI window of these 4 SIs is 8 radio frames, so the first value is 8 radio frames.

[0125] For example, the first value can be the greatest common divisor of the periods of the SI windows of multiple SIs. For instance, the periods of the SI windows of the scheduled SI1, SI2, SI3 and SI4 can be 8, 16, 24 and 32 radio frames, respectively; the greatest common divisor of 8, 16, 24 and 32 is 8, so the first value is 8 radio frames.

[0126] In some embodiments, the first information field of the DCI is used to indicate the time-domain resources of a plurality of PDSCHs.

[0127] Optionally, the first information field can be any information field or a specified information field in the DCI.

[0128] Optionally, the first information field may be one or more bits.

[0129] Optionally, the first information field of the DCI is used to schedule the time-domain resources of multiple PDSCHs at once.

[0130] Optionally, the content indicated in the first information field of the DCI is defined by the communication protocol or configured by the SIB. This SIB can be any type of SIB or SIB1, etc.

[0131] Optionally, the first information field of the DCI is used to indicate the PDSCH time-domain resource allocation information for multiple PDSCHs. Here, the PDSCH time-domain resource allocation information can be any form of information, such as an entry, row, column, or cell in a table, etc., as long as the first information field in the DCI is used to indicate the time-domain resources of multiple PDSCHs in one scheduling.

[0132] In some embodiments, the first information field of the DCI is used to indicate an entry in a first table, whereby an entry indicates a time-domain resource of at least one PDSCH. In embodiments of this disclosure, at least one can be one or more.

[0133] Optionally, the name of the first table is not limited; for example, it may be called the PDSCH time-domain resource allocation table.

[0134] Optionally, the first table includes one or more entries; at least one of the entries in the first table indicates the time-domain resources of multiple PDSCHs.

[0135] Optionally, the entry can be indicated by the index of the entry indicated by the first information field of the DCI. For example, if the first information field of the DCI is "001" or a first value, it can be used to indicate the first entry in the first table; if the first information field of the DCI is "010" or a second value, it can be used to indicate the second entry in the first table; and so on.

[0136] Optionally, an entry may indicate at least one of the following for at least one PDSCH: first symbol position, second symbol position, first time domain length, first time interval, time domain resource position, and resource mapping information.

[0137] For example, the first symbol position is the time-domain start symbol position of the PDSCH. For instance, the first symbol position can be any symbol in any time slot. For example, the time-domain start symbol position of the PDSCH is the k-th symbol.

[0138] For example, the second symbol position is the time-domain end symbol position of the PDSCH. For instance, the second symbol position can be any symbol in any time slot. For example, the time-domain end symbol position of the PDSCH is the (k+i)th symbol.

[0139] For example, the first time-domain length is the length of the time-domain symbol in which the PDSCH is located. For instance, the first time-domain length can be at least one symbol or any time unit length. For example, if the time-domain start symbol position of the PDSCH is the k-th symbol and the time-domain end symbol position of the PDSCH is the (k+i)-th symbol, then the time-domain symbol length in which the PDSCH is located can be i symbols.

[0140] For example, the first time-domain interval is the time-domain interval between the time-domain unit where the PDSCH is located and the time-domain unit of the scheduled DCI. For example, the first time-domain interval can be at least one symbol, at least one time slot, or any time-domain length. For example, if the time-domain unit of the scheduled DCI is the k-th time slot and the time-domain unit where the PDSCH is located is the (k+j)-th time slot, then the first time interval can be j time slots.

[0141] For example, the time-domain resource location is used to indicate the relative time-domain location of the DMRS in the PDSCH. For instance, if the PDSCH starts from symbol 6 and the DMRS occupies symbol 2 relative to the PDSCH (i.e., the relative time-domain location), then the DMRS is at symbol 8 (i.e., the absolute time-domain location). Here, the encoded bits, after modulation, need to be mapped to resource elements (REs); when mapping to REs, symbol locations containing the DMRS need to be avoided, therefore the time-domain resource location of the PDSCH can be configured.

[0142] For example, resource mapping information is used to indicate the resource mapping method of PDSCH.

[0143] For example, under different PDSCH resource mappings, the mapping method of DMRS in PDSCH is different.

[0144] Optionally, the time-domain resources of a PDSCH include at least one of the following: a first symbol position, a second symbol position, a first time-domain length, a first time interval, a time-domain resource position, and resource mapping information.

[0145] Optionally, when an entry is used to indicate the time-domain resource of a PDSCH, it may be: the entry is used to indicate at least one of the following of the PDSCH: first symbol position, second symbol position, first time-domain length, first time interval, time-domain resource position, and resource mapping information.

[0146] Optionally, when an entry is used to indicate the time-domain resources of multiple PDSCHs, it may be: the entry is used to indicate the time-domain resources of each PDSCH in the multiple PDSCHs; or, an entry is used to indicate the time-domain resources of the first PDSCH in the multiple PDSCHs, and the time-domain resources of the other PDSCHs in the multiple PDSCHs, excluding the first PDSCH, are determined based on the time-domain resources of the first PDSCH.

[0147] Optionally, when an entry is used to indicate the time-domain resources of multiple PDSCHs, at least a portion of the time-domain resources of each PDSCH in the multiple PDSCHs may be the same or different. For example, the first time-domain length of each PDSCH in the multiple PDSCHs may be the same or different; the first time-domain interval of each PDSCH in the multiple PDSCHs may be the same or different; the time-domain resource location of each PDSCH in the multiple PDSCHs may be the same or different; and the resource mapping information of each PDSCH in the multiple PDSCHs may be the same or different.

[0148] Optionally, when an entry is used to indicate the time-domain resources of multiple PDSCHs, the time-domain resources of each PDSCH can be configured individually or in association.

[0149] For example, when an entry is used to indicate the time-domain resources of multiple PDSCHs, one implementation is as follows: an entry is used to indicate the time-domain resources of each PDSCH of the multiple PDSCHs. For example, if the multiple PDSCHs are PDSCH1, PDSCH2, and PDSCH3, then an entry can indicate at least one of the following: the first symbol positions of PDSCH1, PDSCH2, and PDSCH3 are the first symbol of the first time slot, the second symbol of the second time slot, and the second symbol of the third time slot, respectively; the second symbol positions of PDSCH1, PDSCH2, and PDSCH3 are the fifth symbol of the first time slot, the sixth symbol of the second time slot, and the seventh symbol of the third time slot, respectively; the second symbol positions of PDSCH1, PDSCH2, and PDSCH3 are the fifth symbol of the first time slot, the sixth symbol of the second time slot, and the seventh symbol of the third time slot, respectively; the second symbol positions of PDSCH1, PDSCH2, and PDSCH3 are the fifth symbol of the first time slot, the sixth symbol of the second time slot, and the seventh symbol of the third time slot, respectively; the third symbol positions of PDSCH1, PDSCH2, and PDSCH3 are the sixth symbol of the first time slot, the sixth symbol of the second time slot, and the seventh symbol of the third time slot, respectively; the fourth symbol positions of PDSCH1, PDSCH2, and PDSCH3 are the sixth symbol of the first time slot, the sixth symbol of the second time slot, and the seventh symbol of the third time slot, respectively; the fifth ... The first time domain length 0 consists of 4 symbols, 4 symbols, and 5 symbols, respectively; the first time intervals of PDSCH1, PDSCH2, and PDSCH3 are 1 symbol per time slot, 2 symbols per time slot, and 2 symbols per time slot, respectively; the time domain resource positions of PDSCH1, PDSCH2, and PDSCH3 occupy the first symbol of the first time slot, the second symbol of the second time slot, and the second symbol of the third time slot, respectively; the resource mapping methods of PDSCH1, PDSCH2, and PDSCH3 are the first mapping method, the first mapping method, and the second mapping method, respectively. Here, when an entry is used to indicate the time domain resources of each PDSCH of multiple PDSCHs, the time domain resources of each PDSCH can be at least partially the same or at least partially different.

[0150] For example, one entry is used to indicate the time-domain resources of multiple PDSCHs. Another implementation is that one entry is used to indicate the time-domain resources of the first PDSCH among the multiple PDSCHs, and the time-domain resources of the other PDSCHs besides the first PDSCH are determined based on the time resources of the first PDSCH. For example, if the multiple PDSCHs are PDSCH1, PDSCH2, and PDSCH3, then one entry can indicate at least one of the following: the first symbol position of PDSCH1 (i.e., the first PDSCH) is the first symbol in the first time slot; the second symbol position of PDSCH1 is the fifth symbol in the first time slot; the first time-domain length of PDSCH1 is 4 symbols; the first time interval of PDSCH1 is 1 time slot; the time-domain resource position of PDSCH is the first symbol in the first time slot; and the resource mapping information of PDSCH1 can be a first mapping method. The time-domain resources of PDSCH2 and PDSCH3 can then be configured according to the protocol and default settings. For example, the first symbol positions of PDSCH2 and PDSCH3 can be configured as the first symbol of the second time slot and the first symbol of the third time slot, respectively (the symbols of PDSCH2 and PDSCH3 are the same as those of PDSCH1, but in different time slots); the second symbol positions of PDSCH2 and PDSCH3 can be configured as the fifth symbol of the second time slot and the fifth symbol of the third time slot, respectively (the symbols of PDSCH2 and PDSCH3 are the same as those of PDSCH1). (The symbols are the same, but they are located in different time slots); the first time domain length of PDSCH2 and PDSCH3 is 4 symbols (the same as the first time domain length of PDSCH1); the first time interval of PDSCH2 and PDSCH3 is 2 time slots and 3 time slots, respectively; the time domain resource positions of PDSCH2 and PDSCH3 are the first symbol of the second time slot and the first symbol of the third time slot, respectively; the resource mapping information of PDSCH2 and PDSCH can both be the first mapping method (the same as the resource mapping method of PDSCH1). Here, when an entry is used to indicate the time domain resources of each PDSCH of multiple PDSCHs, the time domain resources of each PDSCH can be at least partially the same or at least partially different.

[0151] For example, based on the above embodiments, an entry may also indicate an offset value, and the time-domain resources of the other PDSCHs can be determined based on the time-domain resources and offset value of the first PDSCH. For example, if an entry indicates that the first symbol position of PDSCH1 (i.e., the first PDSCH) is the first symbol of the first time slot and an offset value of one time slot, then the first symbol positions of PDSCH2 and PDSCH3 are configured as the first symbol of the second time slot and the first symbol of the third time slot, respectively; if an entry indicates that the first time-domain length of PDSCH1 is four symbols and an offset value of one symbol, then the first time-domain lengths of PDSCH2 and PDSCH3 can both be five symbols.

[0152] Optionally, when the first table includes multiple entries, the time-domain resources of the PDSCH indicated by each of the multiple entries can be configured individually or in association, or the time-domain resources of the PDSCH indicated by each of the entries can be at least partially the same or different.

[0153] For example, the first table includes a first entry and a second entry; among the multiple PDSCHs indicated by the first and second entries, the time domain resources of each PDSCH can be at least partially the same or at least partially different; here, flexible configuration can be implemented.

[0154] Optionally, the first table is defined by the protocol, or the first table is configured by the base station.

[0155] For example, the first table may be agreed upon by the communication protocol or may be determined through negotiation between the base station and the terminal.

[0156] For example, before step S2101, the method further includes: the base station sending first information to the terminal, the first information being used to indicate a first table. Here, the first information can be replaced by a system message other than the one being scheduled or an SIB, etc.

[0157] In some embodiments, the first symbol position, the second symbol position, the first time domain length, the first time interval, the time domain resource position, and the resource mapping information can all be one or more bits.

[0158] In some embodiments, the names of the first symbol position, the second symbol position, the first time domain length, the first time interval, the time domain resource position, and the resource mapping information are not limited; the first symbol position can be the start symbol position, etc.; the second symbol position can be empty, such as the end symbol position, etc.

[0159] In some embodiments, terms such as “send,” “transmit,” “report,” “distribute,” “transmit,” “bidirectional transmission,” “send and / or receive” can be used interchangeably.

[0160] In some embodiments, the names of information, etc., are not limited to the names described in the embodiments. Terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "bit", and "data" can be used interchangeably.

[0161] In some embodiments, terms such as "certain", "preset", "specified", "default", "set", "indicated", "a certain", "any", and "first" can be used interchangeably. "Certain A", "preset A", "specified A", "default A", "set A", "indicated A", "a certain A", "any A", and "first A" can be interpreted as A pre-defined in a protocol or the like, or as A obtained through setting, configuration, or instruction, or as specific A, specified A, a certain A, any A, or first A, but are not limited thereto.

[0162] In step S2102, the base station reschedules the conflicting PDSCH in a non-conflicting time-domain resource. Here, the conflicting PDSCH can be sent without using the conflicting time-domain resource.

[0163] In some embodiments, the base station retransmits the DCI to the terminal using non-conflicting time-domain resources. The DCI is used to schedule conflicting PDSCHs.

[0164] In some embodiments, the terminal receives DCI sent by the base station in a non-conflicting time domain resource, and the DCI is used to schedule conflicting PDSCHs.

[0165] In some embodiments, if the time-domain resource carrying the PDSCH of SI conflicts with the first time-domain resource, the conflicting PDSCH is rescheduled on the non-conflicting time-domain resource.

[0166] In some embodiments, if the time-domain resources carrying the PDSCH of SI conflict with the first time-domain resources, the terminal detects the PDSCH carrying SI on non-conflicting time-domain resources.

[0167] Optionally, the first time-domain resource includes at least one of the following: uplink time-domain resources and downlink time-domain resources that have a higher priority than the time-domain resources of the PDSCH carrying the SI.

[0168] Optionally, the uplink time domain resources can be uplink time domain resources configured in an SIB (e.g., SIB1) or other time domain resources.

[0169] Optionally, downlink time-domain resources that have a higher priority than the time-domain resources of the PDSCH carrying the SI can be the time-domain resources of the SSB.

[0170] Optionally, the conflicting PDSCH may be rescheduled on non-conflicting time-domain resources, including one of the following:

[0171] In the next SI window following the one where the conflict occurred, the conflicting PDSCH is rescheduled.

[0172] Within the SI window of the SI carried by the conflicting PDSCH, the conflicting PDSCH is rescheduled.

[0173] At the second PDCCH listening time following the first PDCCH listening time, the conflicting PDSCH is rescheduled.

[0174] Optionally, the first PDCCH listening time is the PDCCH listening time of the conflicting DCI used for scheduling SI; the second PDCCH listening time is the PDCCH listening time of the non-conflicting DCI used for scheduling SI. Here, at the second PDCCH listening time after the first PDCCH listening time, rescheduling the conflicting PDSCH includes: at the next non-conflicting PDCCH listening time of the DCI used for scheduling SI after the conflicting PDCCH listening time, rescheduling the conflicting PDSCH.

[0175] Optionally, the PDSCH carrying the SI is detected on non-conflicting time-domain resources, including one of the following:

[0176] In the next SI window following the one where the conflict occurred, detect the PDSCH carrying the SI;

[0177] Within the SI window of the SI carried by the conflicting PDSCH, detect the PDSCH carrying the SI.

[0178] At the second PDCCH listening time following the first PDCCH listening time, the PDSCH carrying SI is detected.

[0179] For example, as shown in Figure 2C, the multiple scheduled SIs can be SI1, SI2, SI3, and SI4, respectively; the SI windows corresponding to SI1, SI2, SI3, and SI4 are SI window 1, SI window 2, SI window 3, and SI window 4, respectively. The base station can transmit a DCI in SI window 1 of SI1 (e.g., frame 0), which is used to schedule four PDSCHs; these four PDSCHs are used to carry SI1, SI2, SI3, and SI4, respectively. For example, the DCI for scheduling SIs can be transmitted in the first time slot of frame 0, and PDSCHs for carrying SI1, SI2, SI3, and SI4 can be scheduled in the first to fourth time slots of frame 0, respectively. The base station can also transmit the DCI for scheduling SIs in the window of SI1 (e.g., frame 8), and PDSCHs for carrying SI1 and SI2 can be scheduled in the first to second time slots of frame 8, respectively.

[0180] For example, as shown in Figure 2D, the multiple scheduled SIs can be SI1, SI2, SI3, and SI4, respectively; the SI windows corresponding to SI1, SI2, SI3, and SI4 are SI window 1, SI window 2, SI window 3, and SI window 4, respectively. The base station can send a DCI in SI window 1 of SI1 (e.g., frame 0), which is used to schedule 4 PDSCHs; these 4 PDSCHs are used to carry SI1, SI2, SI3, and SI4, respectively. For example, the DCI for scheduling SIs is sent in the first time slot of frame 0, and the PDSCHs for carrying SI1, SI2, SI3, and SI4 are scheduled in the first to fourth time slots of frame 0, respectively. However, if other resources conflict with the resources carrying the PDSCH of SI3, the scheduling of the PDSCH of SI3 in the third time slot of frame 0 is skipped; and the PDSCH carrying SI3 is rescheduled in SI window 3 of SI3 (e.g., frame 2), such as by sending DCI in the first time slot of frame 2 to schedule the PDSCH of SI3 (i.e., the PDSCH carrying SI3 in the first time slot of frame 2). Optionally, the base station may also send DCI in SI window 2 of SI2 (e.g., frame 2), SI window 4 of SI4 (e.g., frame 3), or any frame after SI window 1 of SI (e.g., frame 0) to schedule the PDSCH carrying SI3.

[0181] For example, as shown in Figure 2E, the multiple SIs to be scheduled can be SI1, SI2, SI3, and SI4, respectively; the SI windows corresponding to SI1, SI2, SI3, and SI4 are SI window 1, SI window 2, SI window 3, and SI window 4, respectively. The base station can send a DCI in SI window 1 of SI1 (e.g., frame 0), which is used to schedule 4 PDSCHs; these 4 PDSCHs are used to carry SI1, SI2, SI3, and SI4, respectively. For example, the DCI for scheduling SIs is sent in the first time slot of frame 0, and the PDSCHs for carrying SI1, SI2, SI3, and SI4 are scheduled in the first to fourth time slots of frame 0, respectively. However, if other resources conflict with the resources carrying the PDSCH of SI3, the scheduling of the PDSCH of SI3 in the 3rd time slot of frame 0 is skipped; and DCI can be sent in the 5th time slot of SI1's SI window 1 (e.g., frame 0) and any time slot after the 5th time slot to schedule the PDSCH carrying SI3 (e.g., scheduling the PDSCH carrying SI3 in the 5th time slot of frame 0 or any time slot after the 5th time slot). Here, the PDSCH can be scheduled on any non-conflicting resource after a conflict occurs. In this way, conflicting PDSCHs can be scheduled in a smaller granular time domain unit, thereby saving transmission resources.

[0182] In some embodiments, “get,” “obtain,” “receive,” “transmit,” “send and / or receive” can be used interchangeably and can be interpreted as receiving from other entities, obtaining from protocols, obtaining from higher layers, obtaining through self-processing, or autonomously implementing, among other meanings.

[0183] The information processing method disclosed herein may include at least one of steps S2101 to S2102. For example, step S2101 may be implemented as a standalone embodiment; step S2102 may be implemented as a standalone embodiment; a combination of steps S2101 and S2102 may be implemented as a standalone embodiment.

[0184] In some embodiments, step S2101 may be optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0185] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0186] Figure 3 is an interactive schematic diagram illustrating an information processing method according to an embodiment of the present disclosure. As shown in Figure 3, this embodiment of the present disclosure relates to an information processing method for a communication system 100, the method including one of the following steps:

[0187] In step S3101, the base station sends a DCI in the first SI window, where the DCI is used to schedule multiple PDSCHs; the multiple PDSCHs are used to carry SIs. Optionally, one PDSCH is used to carry one or more SIs.

[0188] The optional implementations of step S3101 can be found in the optional implementations of step S2101 in Figure 2A, as well as other related parts in the embodiments involved in Figure 2A, which will not be repeated here.

[0189] In some embodiments, the first information field of the DCI is used to indicate the time-domain resources of a plurality of PDSCHs; or, the first information field of the DCI is used to indicate an entry in a first table, wherein an entry is used to indicate the time-domain resources of at least one PDSCH.

[0190] In some embodiments, the first table is defined by the protocol, or the first table is configured by the base station.

[0191] In some embodiments, the first SI window is one of the following: any SI window among the SI windows of the multiple scheduled SIs; or the SI window with the smallest index value among the SI windows of the multiple scheduled SIs.

[0195] In some embodiments, the method further includes: when the time-domain resources of the PDSCH carrying SI conflict with the first time-domain resources, the base station reschedules the conflicting PDSCH on non-conflicting time-domain resources.

[0196] In some embodiments, the first time-domain resource includes at least one of the following: uplink time-domain resources; downlink time-domain resources with higher priority than the time-domain resources of the PDSCH carrying SI.

[0197] In some embodiments, rescheduling a conflicting PDSCH on a non-conflicting time-domain resource includes one of the following: rescheduling the conflicting PDSCH in the next SI window after the conflicting SI window; rescheduling the conflicting PDSCH in the SI window of the SI carried by the conflicting PDSCH; or rescheduling the conflicting PDSCH in the next non-conflicting PDCCH listening time of the DCI used for scheduling SI after the PDCCH listening time of the conflicting DCI used for scheduling SI.

[0200] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0201] This disclosure relates to an information processing method, which may include at least one of the following:

[0202] In some embodiments, for periodically broadcast SIs, a base station transmits a DCI scrambled with SI-RNTI in an SI window. This DCI schedules multiple PDSCHs, which are used to carry multiple SIs respectively. The SI windows of these multiple SIs are adjacent in the time domain.

[0203] Optionally, the periodicity of the SI window of the multiple SIs is a multiple of the first value, for example, the first value may be the minimum of the SI window periodicity of the multiple SIs.

[0204] Optionally, the SI window for sending the DCI to the scheduled SI can be one of the adjacent SI windows. Here, we take the SI window with the smallest SI index as an example.

[0205] In some embodiments, PDSCH time-domain resource allocation information for DCI to schedule multiple PDSCHs at once can be defined in the protocol or configured in SIB1.

[0206] Optionally, a PDSCH time-domain resource allocation table (e.g., the first table in the previous embodiment) is defined or configured, which contains one or more entries; at least one entry may include indication information for multiple PDSCH time-domain resources. Each PDSCH time-domain resource indication information includes at least one of the following:

[0207] The starting symbol position in the time domain of PDSCH; for example, the starting time domain position of PDSCH is the kth symbol in the slot;

[0208] Time-domain symbol length of PDSCH;

[0209] The time interval between the time domain unit (e.g., time slot) where the PDSCH is located and the time domain unit that schedules the DCI (if there are multiple PDSCH time domain resources in an entry, each PDSCH time domain resource may have this time interval, or only the first PDSCH time domain resource may have this time interval, and the time domain units where the other PDSCH time domain resources are located are shifted sequentially after the time domain unit of the first PDSCH time domain resource).

[0210] The time-domain resource location of PDSCH DMRS: the relative time-domain location of DMRS in PDSCH; for example, the time-domain resource location is the nth symbol in the time-domain symbols occupied by PDSCH, or the time-domain symbol index of DMRS in the time slot where PDSCH is located;

[0211] The resource mapping method of PDSCH; under different PDSCH resource mapping methods, the mapping method of DMRS in PDSCH is different.

[0212] Optionally, when the base station schedules PDSCHs used to carry SIs, the DCI scrambled with SI-RNTI indicates which entry in the aforementioned PDSCH time-domain resource allocation table should be applied. For example, if the table has a total of 9 entries, the DCI can have 3 bits used to indicate the index of the entry to be applied; when the indicated index includes 1 PDSCH time-domain resource, then 1 PDSCH is scheduled according to the indication of that time-domain resource; when the indicated index contains N (N>2) PDSCH time-domain resources, then N PDSCHs are scheduled according to the indication of those N time-domain resources. Each PDSCH can carry 1 SI.

[0213] Optionally, as shown in Figure 2D, if a time-domain resource conflict occurs, for example, the resource used to carry the PDSCH for SI conflicts with the time-domain resource configured as UL in SIB1, or the PDSCH carrying SI conflicts with the time-frequency resource of SSB, the base station will not transmit the PDSCH carrying SI on the conflicting resource, i.e., skip the conflicting PDSCH resource. However, the SI that is not transmitted due to the conflict can be handled as follows: if the time-domain resource of the PDSCH scheduled by DCI conflicts, it can be rescheduled for transmission in a subsequent SI window; or, the SI can be rescheduled in the SI window of the SI carried by the conflicted PDSCH, as shown in Figure 2D.

[0214] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.
