[0062] To facilitate understanding by those skilled in the art, the embodiments of the present disclosure list multiple implementation methods to clearly illustrate the technical solutions of the embodiments of the present disclosure. Of course, those skilled in the art will understand that the multiple embodiments provided in the embodiments of the present disclosure can be implemented individually, or can be implemented together with the methods of other embodiments in the embodiments of the present disclosure, or can be implemented together with some methods in other related technologies individually or in combination; the embodiments of the present disclosure do not limit this.
[0063] In each embodiment of the present disclosure, unless otherwise specified or provided for by logic, the terms and / or descriptions between the embodiments are consistent and can be referenced by each other. The technical features in different embodiments can be combined to form a new embodiment based on their inherent logical relationships.
[0064] The terms used in the embodiments of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure.
[0065] In order to improve uplink coverage and throughput, duplex enhancement has been studied for sub-band full duplex (SBFD).
[0066] In some embodiments, a carrier component (CC) is divided into multiple subbands (SBs) in the frequency domain on a downlink or flexible (F) symbol, and the multiple SBs include one UL subband (UL subband) and at least one (1 or 2) DL subbands (DL subband). The base station can send DL signals on the DL subband and receive UL signals on the UL subband at the same time.
[0067] In some examples, DL or F symbols may be configured in at least one of the following ways:
[0068] Common signaling, such as TDD-UL-DL-ConfigCommon configuration;
[0069] Dedicated signaling, such as TDD-UL-DL-ConfigDedicated configuration;
[0070] The physical layer signaling may be, for example, a DCI format 2_0 indication.
[0071] In some examples, a time slot (Slot) contains multiple symbols, for example, for a normal cyclic prefix (Normal CP), each time slot contains 14 orthogonal frequency division multiplexing (OFDM) symbols; for an extended cyclic prefix (Extended CP), each time slot contains 12 OFDM symbols.
[0072] In the embodiment of the present disclosure, a symbol includes both a DL subband and a UL subband in the frequency domain, and the symbol may be called an SBFD symbol.
[0073] When a time slot includes at least one SBFD symbol among multiple symbols included in the time slot, the time slot may be called a SBFD time slot.
[0074] Referring to FIG. 2 a , time slot n is a DL time slot, time slots n+1 to n+3 are SBFD time slots, and time slot n+4 is a UL time slot.
[0075] All the symbols included in the DL time slot are downlink (DL) symbols, and all the symbols included in the UL time slot are uplink (UL) symbols.
[0076] In some embodiments, when all the multiple symbols included in a time slot are SBFD symbols, the time slot may be called a SBFD time slot.
[0077] In some embodiments, a guard band (GB) may exist between the DL subband and the UL subband to reduce interference between DL signals in the DL subband and UL signals in the UL subband through frequency domain isolation.
[0078] In some embodiments, downlink control information (DCI) indicates that the physical downlink shared channel (PDSCH) is transmitted in multiple time slots and can be in the following forms:
[0079] 1. In PDSCH aggregation or repetition transmission, the DCI indicates that the PDSCH is to be received in k consecutive time slots.
[0080] 2. In semi-persistent scheduling (SPS) PDSCH transmission, DCI activates the SPS PDSCH configured by Radio Resource Control (RRC), and the terminal periodically receives the PDSCH on certain time domain resources.
[0081] In some examples, the number of repetitions k of the SPS PDSCH can be configured via RRC.
[0082] 3. When one DCI schedules multiple PDSCH transmissions, the DCI indicates at least one of the following: one frequency domain resource allocation, multiple time domain resource allocations, and PDSCH reception on multiple time-frequency resources.
[0083] In some embodiments, the frequency domain (FD) range available for DL transmission in SBFD symbols may be discontinuous. One possible scenario is when the GB and UL subbands are unavailable for DL transmission. In this case, the frequency domain range available for DL transmission in DL symbols differs from that in SBFD symbols. The DCI instructs the UE to receive PDSCH in multiple time slots. Within a time slot, the frequency domain (FD) range for SBFD symbols and non-SBFD symbols containing the PDSCH must be determined.
[0084] In some embodiments, the DCI instructs the UE to receive PDSCH in multiple time slots. The PDSCH may be: PDSCH repeated transmission, SPS PDSCH with or without repeated transmission, or multiple PDSCHs scheduled by a single DCI.
[0085] (1) PDSCH repeated transmission
[0086] Configuration parameters in RRC: pdsch-AggregationFactor, ENUMERATED{n2,n4,n8};
[0087] According to the frequency domain range FD#1 indicated by the DCI, the PDSCH is received in k consecutive time slots, where k=pdsch-AggregationFactor.
[0088] (2) SPS PDSCH with or without repeated transmission
[0089] Configuration parameters in RRC: PDSCH period P, number of HARQ processes, number of repetitions k = pdsch-AggregationFactor-r16, ENUMERATED{n1,n2,n4,n8} and other information.
[0090] If pdsch-AggregationFactor-r16 is not configured, the number of repetitions k is determined according to the pdsch-AggregationFactor in the PDSCH-config cell.
[0091] PDSCH is received periodically according to the time-frequency range indicated by DCI.
[0092] (3) Single DCI schedules multiple PDSCHs
[0093] Please refer to Figure 2b. According to the multiple time domain ranges indicated by the DCI, a frequency domain range FD#1, the UE receives PDSCH#0, PDSCH#1, PDSCH#2, and PDSCH#3 in FD#1 within the indicated multiple time domain ranges.
[0094] Please refer to Figure 2c. The symbol where PDSCH#0 is located is a DL symbol, while the symbols where PDSCH#1, PDSCH#2, and PDSCH#3 are located are all SBFD symbols, and overlap with the outside of the DL frequency domain range (the outside of the DL frequency domain range cannot be used for DL transmission). In this case, it is necessary to determine the frequency domain range used by PDSCH#0, PDSCH#1, PDSCH#2, and PDSCH#3.
[0095] FIG3 is a flow chart of an information processing method according to an exemplary embodiment. The information processing method is executed by a terminal. As shown in FIG3 , the information processing method may include the following steps:
[0096] S101: Receive DCI; DCI is used to indicate multiple PDSCH transmissions in multiple time slots;
[0097] S102: Determine a frequency domain range for PDSCH transmission on a symbol used for PDSCH transmission in each time slot according to the DCI; wherein the symbol includes at least one of an SBFD symbol and a non-SBFD symbol.
[0098] In some examples, the terminal may be various mobile terminals or fixed terminals, including but not limited to mobile phones, wearable devices, Internet of Things devices, etc.
[0099] In some examples, a terminal receives DCI sent by a network device. The network device may be a base station, such as a gNB.
[0100] In some examples, PDSCH transmission is used for transmission of downlink data, such as transmission of unicast data, paging signals, random access response messages, and other data.
[0101] In some examples, the multiple PDSCH transmissions indicated by the DCI may be multiple different PDSCH transmissions or multiple repeated transmissions of the same PDSCH.
[0102] In some examples, DCI is used to instruct the terminal to receive PDSCH in multiple time slots, for example, DCI is used to instruct the terminal to perform PDSCH repetition transmission in multiple time slots, SPS PDSCH with or without repetition transmission, or to instruct the terminal to receive multiple PDSCH transmissions scheduled by a single DCI.
[0103] In some examples, DCI may be used to indicate time domain resource information for PDSCH transmission.
[0104] For example, the time domain resource information includes information such as the time slot position, the starting symbol position within the time slot, and the time domain length. The time domain length can be used to indicate the number of consecutive symbols allocated to the PDSCH, counting from the starting symbol position.
[0105] For example, the time domain resource allocation information of the DCI includes a row index, and the row index is used by the terminal to search for time domain resource information for PDSCH transmission from a pre-configured time domain resource allocation table.
[0106] In some examples, the DCI may be used to indicate the symbol position occupied by the PDSCH within each of a plurality of slots.
[0107] In some examples, the symbols in a time slot may be all SBFD symbols, or all non-SBFD symbols, or may include both SBFD and non-SBFD symbols.
[0108] In some examples, an SBFD symbol is a symbol that includes both a DL subband and a UL subband in the frequency domain, and a non-SBFD symbol is a symbol that does not include both a DL subband and a UL subband in the frequency domain. For example, a non-SBFD symbol is a DL symbol, a UL symbol, or an F symbol.
[0109] In some examples, the DCI may indicate multiple PDSCH transmissions based on mini-slot scheduling. A mini-slot may consist of a portion of consecutive symbols within a time slot. For example, the length of a downlink mini-slot may be 2, 4, or 7 symbols, and the mini-slot may start at any symbol within a time slot.
[0110] In some examples, the network may notify the terminal of the symbols used for PDSCH transmission in multiple time slots through higher layer signaling or physical layer signaling. For example, the physical layer signaling includes DCI.
[0111] In some examples, symbols used for PDSCH transmission within multiple time slots include SBFD symbols and / or non-SBFD symbols.
[0112] For example, all symbols used for PDSCH transmission in a time slot are non-SBFD symbols; or, all symbols used for PDSCH transmission in a time slot are SBFD symbols; or, symbols used for PDSCH transmission in a time slot include SBFD symbols and non-SBFD symbols.
[0113] In some examples, the types of symbols used for PDSCH transmission in different time slots may be the same or different, for example, the symbols used for PDSCH transmission in time slot n are all non-SBFD symbols, the symbols used for PDSCH transmission in time slot n+1 are all SBFD symbols, and the symbols used for PDSCH transmission in time slot n+2 include SBFD symbols and non-SBFD symbols.
[0114] In some examples, the frequency domain range used for PDSCH transmission in SBFD symbols is the same as or different from the frequency domain range used for PDSCH transmission in non-SBFD symbols.
[0115] In some examples, the DCI may be used to indicate a frequency domain range used for PDSCH transmission in non-SBFD symbols. For example, the FDRA (Frequency Domain Resource Allocation) field in the DCI indicates that the frequency domain range used for PDSCH transmission in non-SBFD symbols is a first frequency domain range.
[0116] In some examples, the frequency domain range of the PDSCH transmission is used to indicate the frequency domain position occupied by the PDSCH transmission.
[0117] In some examples, the frequency domain range can be characterized by a resource grid (RG), a bandwidth part (BWP), a physical resource block (PRB) and / or a resource block (RB).
[0118] In some examples, in an SBFD symbol, a frequency domain range that can be used for DL transmission is called a DL frequency domain range, and a frequency domain range that cannot be used for DL transmission is called a non-DL frequency domain range.
[0119] In some examples, the DL frequency domain range may be a frequency domain range where the DL subband overlaps with the BWP.
[0120] As shown in Figure 4, slot n is a DL slot, slots n+1 through n+3 are SBFD slots, and slot n+4 is a UL slot. The symbols in slot n and slot n+4 are non-SBFD symbols, while the symbols in slots n+1 through n+3 are SBFD symbols. In an SBFD symbol, the DL frequency domain range can be the frequency domain range where the DL subband overlaps with the BWP. The frequency domain range where the GB and UL subband overlap with the BWP is the non-DL frequency domain range.
[0121] In other examples, the DL frequency domain range may be a frequency domain range where a DL subband and a GB overlap with a BWP.
[0122] In some examples, the frequency domain range used for PDSCH transmission in the SBFD symbol is the second frequency domain range, and the second frequency domain range can be a frequency domain range that overlaps the first frequency domain range indicated by the DCI and the DL frequency domain range in the SBFD symbol.
[0123] An embodiment of the present disclosure provides an information processing method, which receives DCI; wherein the DCI is used to indicate multiple PDSCH transmissions in multiple time slots; based on the DCI, a frequency domain range for PDSCH transmission is determined on the symbol used for PDSCH transmission in each time slot; wherein the symbol includes at least one of an SBFD symbol and a non-SBFD symbol. In this way, the frequency domain ranges on the SBFD symbol and the non-SBFD symbol where the PDSCH transmission is located can be clearly determined, which can improve the reliability of the PDSCH transmission and can make up for the deficiency in the prior art of how to determine the frequency domain range of the PDSCH transmission in the SBFD symbol.
[0124] In some embodiments, the method may further comprise the steps of:
[0125] Receive first information; the first information is used to indicate at least one of the following:
[0126] The types of symbols that can be used for multiple PDSCH transmissions;
[0127] The type of symbols that can be used by any one of multiple PDSCH transmissions.
[0128] In this embodiment, by receiving the first information, since the first information clearly indicates the categories of symbols that can be used for multiple PDSCH transmissions and at least one of the categories of symbols that can be used for any one of the multiple PDSCH transmissions, the category of symbols that can be used for PDSCH transmission can be clearly determined, which improves the reliability of executing multiple PDSCH transmissions compared to the case where the symbol category is uncertain.
[0129] In some embodiments, the first information is used to indicate at least one of the following:
[0130] Multiple PDSCH transmissions can use SBFD symbols and non-SBFD symbols, and any one of the multiple PDSCH transmissions can use SBFD symbols or non-SBFD symbols;
[0131] Multiple PDSCH transmissions can use SBFD symbols and non-SBFD symbols, and any one of the multiple PDSCH transmissions can use SBFD symbols and non-SBFD symbols;
[0132] Multiple PDSCH transmissions can use SBFD symbols, and any one of the multiple PDSCH transmissions can use SBFD symbols;
[0133] The multiple PDSCH transmissions can use non-SBFD symbols, and any one of the multiple PDSCH transmissions can use non-SBFD symbols.
[0134] Multiple PDSCH transmissions can use both SBFD and non-SBFD symbols. Any one of the multiple PDSCH transmissions can use only SBFD or non-SBFD symbols. As shown in Figure 5a, PDSCH#0 through PDSCH#3 can use both SBFD and non-SBFD symbols. PDSCH#0 uses non-SBFD symbols, while PDSCH#1 through PDSCH#3 use SBFD symbols.
[0135] Multiple PDSCH transmissions can use both SBFD and non-SBFD symbols, and any one of the multiple PDSCH transmissions can use both SBFD and non-SBFD symbols. As shown in Figure 5b , PDSCH#0 through PDSCH#3 can use both SBFD and non-SBFD symbols. PDSCH#0 uses non-SBFD symbols, PDSCH#1 through PDSCH#2 use both SBFD and non-SBFD symbols, and PDSCH#3 uses SBFD symbols.
[0136] Multiple PDSCH transmissions can use SBFD symbols, and any one of the multiple PDSCH transmissions can use SBFD symbols. Referring to FIG5c , PDSCH#1 to PDSCH#3 transmissions use SBFD symbols, and any one of PDSCH#1 to PDSCH#3 transmissions uses SBFD symbols.
[0137] Multiple PDSCH transmissions can use non-SBFD symbols, and any one of the multiple PDSCH transmissions can use non-SBFD symbols. Referring to Figure 5d , PDSCH#0 to PDSCH#1 transmissions use non-SBFD symbols, and any one of the PDSCH transmissions from PDSCH#0 to PDSCH#1 uses non-SBFD symbols.
[0138] In this embodiment, the first information clearly indicates symbols that can be used to perform multiple PDSCH transmissions and symbols that can be used to perform any one of the multiple PDSCH transmissions, so that the multiple PDSCH transmissions are more reliable.
[0139] In some embodiments, receiving the first information may include:
[0140] Receive first information sent via a first message; wherein the first message includes: at least one of a DCI message, a radio resource control (RRC) message, a media access control (MAC) control element (CE) message, and a system information block (SIB).
[0141] In some embodiments, the terminal receives the first information sent by the network device through a DCI message.
[0142] In some embodiments, the terminal receives the first information sent by the network device through an RRC message.
[0143] In some embodiments, the terminal receives the first information sent by the network device through a MAC CE message.
[0144] In some embodiments, the terminal receives the first information sent by the network device through a SIB1 message.
[0145] In this embodiment, the first information can be received by reusing messages in the communication process, which can reduce signaling overhead, reduce resource consumption, and improve resource utilization efficiency.
[0146] In some embodiments, in step S102, determining the frequency domain range for PDSCH transmission on the symbol for PDSCH transmission in each time slot according to the DCI may include at least one of the following:
[0147] For any time slot, the symbol used for PDSCH transmission in the time slot is a non-SBFD symbol, and the frequency domain range used for PDSCH transmission in the non-SBFD symbol is determined to be a first frequency domain range; the first frequency domain range is: the frequency domain range indicated by the DCI for the non-SBFD symbol;
[0148] For any time slot, the symbol used for PDSCH transmission in the time slot is an SBFD symbol, and the frequency domain range used for PDSCH transmission in the SBFD symbol is determined to be the target frequency domain range.
[0149] In some examples, the FDRA field in the DCI indicates that the frequency domain range used for PDSCH transmission in non-SBFD symbols is the first frequency domain range.
[0150] In some examples, the target frequency domain range may be the same as or different from the first frequency domain range.
[0151] In this embodiment, by determining the frequency domain range used for PDSCH transmission in non-SBFD symbols as the first frequency domain range, and determining the frequency domain range used for PDSCH transmission in SBFD symbols as the target frequency domain range, the frequency range used when receiving PDSCH transmission on non-SBFD symbols and SBFD symbols is determined, so that the UE can receive PDSCH transmission at the correct location, thereby improving the reliability of PDSCH transmission. In some embodiments, the target frequency domain range is a second frequency domain range, where the second frequency domain range is: a frequency domain range that overlaps the first frequency domain range and the DL frequency domain range in the SBFD symbol.
[0152] In this embodiment, for any time slot, if the symbol used for PDSCH transmission in the time slot is a non-SBFD symbol, the frequency domain range used for PDSCH transmission in the non-SBFD symbol of the time slot is determined to be the first frequency domain range (for example, FD#1); if the symbol used for PDSCH transmission in the time slot is a SBFD symbol, the frequency domain range used for PDSCH transmission in the SBFD symbol of the time slot can be determined to be the second frequency domain range (for example, FD#2).
[0153] In some examples, for any time slot, the symbols used for PDSCH transmission in the time slot are only SBFD symbols or non-SBFD symbols. The frequency domain range used for PDSCH transmission in non-SBFD symbols is a first frequency domain range, and the frequency domain range used for PDSCH transmission in SBFD symbols is a second frequency domain range.
[0154] Referring to Figure 6a, slot n is a DL slot, and all symbols in slot n are non-SBFD symbols. Slots n+1 through n+3 are SBFD slots, and all symbols in slots n+1 through n+3 are SBFD symbols. The DCI indicates a frequency domain range of FD#1 for non-SBFD symbols, which indicates that the frequency domain range used for PDSCH#0 transmission by the non-SBFD symbols in slot n is FD#1. The symbols used for PDSCH#1 transmission in slot n+1 are SBFD symbols, which indicates that the frequency domain range used for PDSCH#1 transmission by the SBFD symbols in slot n+1 is FD#2. The symbols used for PDSCH#2 transmission in slot n+2 are SBFD symbols, which indicates that the frequency domain range used for PDSCH#2 transmission by the SBFD symbols in slot n+2 is FD#2. The symbol used for PDSCH#3 transmission in time slot n+3 is an SBFD symbol. Therefore, the frequency domain range used for PDSCH#3 transmission in the SBFD symbol in time slot n+3 can be determined to be FD#2. FD#2 is the frequency domain range where FD#1 overlaps with the DL frequency domain range in the SBFD symbol.
[0155] In other examples, the symbols used for PDSCH transmission in a time slot may include SBFD symbols and non-SBFD symbols. The frequency domain range used for PDSCH transmission in the non-SBFD symbols is a first frequency domain range, and the frequency domain range used for PDSCH transmission in the SBFD symbols is a second frequency domain range.
[0156] Referring to Figure 6b , time slot n is a DL time slot, and the symbols of time slot n are all non-SBFD symbols; time slots n+1 to n+3 are all SBFD time slots, and the symbols used for PDSCH#1 transmission in time slot n+1 include non-SBFD symbols and SBFD symbols; the symbols used for PDSCH#2 transmission in time slot n+2 include non-SBFD symbols and SBFD symbols; and the symbols used for PDSCH#3 transmission in time slot n+3 are all SBFD symbols. The DCI indicates the frequency domain range for non-SBFD symbols as FD#1. This indicates that: the frequency domain range used for PDSCH#0 transmission by the non-SBFD symbol in slot n is FD#1; the frequency domain range used for PDSCH#1 transmission by the non-SBFD symbol in slot n+1 is FD#1, and the frequency domain range used for PDSCH#1 transmission by the SBFD symbol in slot n+1 is FD#2; the frequency domain range used for PDSCH#2 transmission by the non-SBFD symbol in slot n+2 is FD#1, and the frequency domain range used for PDSCH#2 transmission by the SBFD symbol in slot n+2 is FD#2; and the frequency domain range used for PDSCH#3 transmission by the SBFD symbol in slot n+3 is FD#2. FD#2 is the frequency domain range where FD#1 overlaps with the DL frequency domain range in the SBFD symbol.
[0157] In this embodiment, by determining the frequency domain range for PDSCH transmission in non-SBFD symbols as the first frequency domain range, and determining the frequency domain range for PDSCH transmission in SBFD symbols as the second frequency domain range, the second frequency domain range is a frequency domain range overlapping the first frequency domain range and the DL frequency domain range in the SBFD symbols, so that the frequency range used for receiving PDSCH transmission on non-SBFD symbols and SBFD symbols is determined, so that the UE can receive PDSCH transmission at the correct position, thereby improving the reliability of PDSCH transmission; in addition, the number of PDSCHs that are canceled in multiple PDSCH transmissions can be reduced as much as possible, so that the number of PDSCH transmissions received in multiple PDSCH transmissions can be increased, thereby improving downlink throughput, and the number of times multiple repeated transmissions of the same PDSCH are received can be increased, thereby increasing downlink coverage; in addition, since no additional signaling is required to indicate the frequency domain range of PDSCH transmission in the SBFD symbol, the implementation is simple, the complexity is low, and the signaling overhead is reduced.
[0158] In some embodiments, the target frequency domain range is a third frequency domain range, wherein the third frequency domain range is: a frequency domain range indicated by the DCI for the SBFD symbol.
[0159] In this embodiment, for any time slot, if the symbol used for PDSCH transmission in the time slot is a non-SBFD symbol, the frequency domain range used for PDSCH transmission in the non-SBFD symbol of the time slot is determined to be the first frequency domain range (for example, FD#1); if the symbol used for PDSCH transmission in the time slot is a SBFD symbol, the frequency domain range used for PDSCH transmission in the SBFD symbol of the time slot can be determined to be the third frequency domain range (for example, FD#3).
[0160] For example, DCI includes two sets of FDRA, and the two sets of FDRA respectively indicate FD#1 and FD#3, where FD#1 is used for non-SBFD symbols and FD#3 is used for SBFD symbols.
[0161] Referring to Figure 6c , slot n is a DL slot, and all symbols in slot n are non-SBFD symbols. Slots n+1 through n+3 are SBFD slots, and all symbols in slots n+1 through n+3 are SBFD symbols. The DCI indicates the frequency domain ranges for non-SBFD symbols as FD#1 and FD#3, respectively. This indicates that the frequency domain ranges for non-SBFD symbols in slot n used for PDSCH#0 transmission are FD#1; the frequency domain ranges for SBFD symbols in slot n+1 used for PDSCH#1 transmission are FD#3; and the frequency domain ranges for SBFD symbols in slot n+2 used for PDSCH#2 transmission are FD#3. The frequency domain range for SBFD symbols in slot n+3 used for PDSCH#3 transmission are FD#3.
[0162] In some examples, if the DCI indicates a third frequency domain range for the SBFD symbol, the priority of using the third frequency domain range is higher than the priority of using the second frequency domain range.
[0163] In this embodiment, by determining the frequency domain range for PDSCH transmission in non-SBFD symbols as the first frequency domain range, and determining the frequency domain range for PDSCH transmission in SBFD symbols as the third frequency domain range, the frequency range used when receiving PDSCH transmission on non-SBFD symbols and SBFD symbols is determined, so that the UE can receive PDSCH transmission at the correct position, thereby improving the reliability of PDSCH transmission; in addition, the number of PDSCHs that are canceled in multiple PDSCH transmissions can be reduced as much as possible, so that the number of PDSCH transmissions received in multiple PDSCH transmissions can be increased, thereby improving downlink throughput, and the number of times the same PDSCH is received for multiple repeated transmissions can be increased, thereby increasing downlink coverage.
[0164] In some embodiments, when a first condition is met, the target frequency domain range is a fourth frequency domain range; wherein the first condition includes: a bandwidth used for DL transmission in the SBFD symbol is greater than or equal to a bandwidth of the first frequency domain range.
[0165] In this embodiment, for any time slot, if the symbol used for PDSCH transmission in the time slot is a non-SBFD symbol, the frequency domain range used for PDSCH transmission in the non-SBFD symbol of the time slot is determined to be the first frequency domain range (for example, FD#1); if the symbol used for PDSCH transmission in the time slot is a SBFD symbol, when the first condition is met, the frequency domain range used for PDSCH transmission in the SBFD symbol of the time slot can be determined to be the fourth frequency domain range (for example, FD#4). In this way, FD adaptation of PDSCH on SBFD symbols and non-SBFD symbols can be achieved, and since the frequency range used for receiving PDSCH transmission on non-SBFD symbols and SBFD symbols is determined, the UE can receive PDSCH transmission at the correct position, thereby improving the reliability of PDSCH transmission.
[0166] In this embodiment, when the bandwidth used in the SBFD symbol is greater than or equal to the bandwidth in the non-SBFD symbol, the frequency domain range used for PDSCH transmission in the SBFD symbol is determined to be the fourth frequency domain range, which can improve the performance of PDSCH transmission in the SBFD symbol, thereby improving the reliability of PDSCH transmission; in addition, since no additional signaling is required to indicate the frequency domain range of PDSCH transmission in the SBFD symbol, the implementation is simple, the complexity is low, and the signaling overhead is reduced.
[0167] It can be understood that when the first condition is met, the bandwidth used for DL transmission in the SBFD symbol is greater than or equal to the bandwidth of the first frequency domain range. In this case, there will be a certain frequency domain range in the SBFD symbol, and the bandwidth used for DL transmission contained in the frequency domain range is equal to the bandwidth of the first frequency domain range, that is, there will be a fourth frequency domain range in the SBFD symbol.
[0168] In some embodiments, the number of RBs included in the fourth frequency domain range is equal to the number of RBs included in the first frequency domain range, and the fourth frequency domain range is a frequency domain range that overlaps the fifth frequency domain range with the frequency domain range used for DL transmission in the SBFD symbol; wherein, the starting RB of the fifth frequency domain range is the starting RB in the BWP, or the ending RB of the fifth frequency domain range is the ending RB in the BWP.
[0169] In some examples, the fourth frequency domain range may be the same as the fifth frequency domain range.
[0170] 6 d , time slot n is a DL time slot, and the symbols of time slot n are all non-SBFD symbols; time slot n+1 to time slot n+3 are all SBFD time slots, and the symbols of time slot n+1 to time slot n+3 are all SBFD symbols. The DCI indicates the frequency domain range for non-SBFD symbols as FD#1. Therefore, the frequency domain range used for PDSCH#0 transmission in the non-SBFD symbol in slot n is determined to be FD#1. If the bandwidth used for DL transmission in the SBFD symbols in slots n+1 through n+3 is greater than or equal to the bandwidth of FD#1, and since the number of RBs included in FD#1 is equal to the number of RBs included in FD#4, the starting RB of the fifth frequency domain range (e.g., FD#1_1) is the starting RB in the BWP, and FD#4 is the frequency domain range where FD#1_1 overlaps with the frequency domain range used for DL transmission in the SBFD symbol, it can be determined that FD#4 is the same as FD#1_1. That is, the frequency domain range used for PDSCH#1 transmission in the SBFD symbol in slot n+1 is FD#4, and the frequency domain range used for PDSCH#2 transmission in the SBFD symbol in slot n+2 is FD#4. The frequency domain range used for PDSCH#3 transmission in the SBFD symbol in slot n+3 is FD#4.
[0171] In other examples, the fourth frequency domain range may be different from the fifth frequency domain range.
[0172] 6e, time slot n is a DL time slot, and the symbols of time slot n are all non-SBFD symbols; time slot n+1 to time slot n+3 are all SBFD time slots, and the symbols of time slot n+1 to time slot n+3 are all SBFD symbols. The DCI indicates the frequency domain range for non-SBFD symbols as FD#1. Therefore, it can be determined that the frequency domain range used for PDSCH#0 transmission in the non-SBFD symbol in slot n is FD#1. If the bandwidth used for DL transmission in the SBFD symbols in slots n+1 to n+3 is greater than or equal to the bandwidth of FD#1, and since the number of RBs included in FD#1 is equal to the number of RBs included in FD#4, the starting RB of the fifth frequency domain range (e.g., FD#1_1) is the starting RB in the BWP, and FD#4 is the frequency domain range where FD#1_1 overlaps with the frequency domain range used for DL transmission in the SBFD symbol, it can be determined that FD#4 is different from FD#1_1. That is, the frequency domain range used for PDSCH#1 transmission in the SBFD symbol in slot n+1 is FD#4, and the frequency domain range used for PDSCH#2 transmission in the SBFD symbol in slot n+2 is FD#4. The frequency domain range used for PDSCH#3 transmission in the SBFD symbol in slot n+3 is FD#4.
[0173] For example, FD#1 includes RB#10 to RB#20, FD#1_1 includes RB#0 to RB#21, and it can be determined that FD#4 includes RB#0 to RB#8 and RB#20 to RB#21.
[0174] In some examples, if the DCI indicates a third frequency domain range for the SBFD symbol, the priority of using the third frequency domain range is higher than the priority of using the fourth frequency domain range.
[0175] In this embodiment, by determining that the frequency domain range used for PDSCH transmission in the SBFD symbol is the fourth frequency domain range, since the number of RBs included in the fourth frequency domain range is equal to the number of RBs included in the first frequency domain range, and the fourth frequency domain range is the frequency domain range that overlaps the fifth frequency domain range and the frequency domain range used for DL transmission in the SBFD symbol, the starting RB of the fifth frequency domain range is the starting RB in the BWP, or the ending RB of the fifth frequency domain range is the ending RB in the BWP, the frequency range used when receiving PDSCH transmission on the SBFD symbol is determined, so that the UE can receive the PDSCH transmission at the correct position, thereby improving the reliability of PDSCH transmission in the SBFD symbol; in addition, the number of PDSCHs that are canceled in multiple PDSCH transmissions can be reduced as much as possible, so that the number of PDSCH transmissions received in multiple PDSCH transmissions can be increased, thereby improving downlink throughput, and the number of times the same PDSCH is received for multiple repeated transmissions can be increased, thereby increasing downlink coverage.
[0176] In some embodiments, the method may further include:
[0177] For any time slot, if the symbols used for PDSCH transmission in the time slot include SBFD symbols and do not meet the first condition, it is determined that the PDSCH in the time slot is not received.
[0178] In this embodiment, in a time slot, the symbol where the PDSCH is transmitted includes at least one SBFD symbol, and the bandwidth used for DL transmission in the SBFD symbol is smaller than the bandwidth of the first frequency domain range, and the PDSCH in the time slot is not received. This facilitates implementation and avoids the additional complex design required to ensure the performance of receiving the PDSCH.
[0179] It can be understood that when the first condition is not met, the bandwidth used for DL transmission in the SBFD symbol is smaller than the bandwidth of the first frequency domain range. In this case, the fourth frequency domain range and the fifth frequency domain range do not exist in the SBFD symbol, so that the fourth frequency domain range is a frequency domain range in which the fifth frequency domain range overlaps with the frequency domain range used for DL transmission in the SBFD symbol, and the bandwidth for DL transmission contained in the fourth frequency domain range is equal to the bandwidth of the first frequency domain range.
[0180] In some embodiments, in the above step S102, determining the frequency domain range for PDSCH transmission on the symbol for PDSCH transmission in each time slot according to the DCI may include:
[0181] Symbols used for PDSCH transmission in at least one time slot include non-SBFD symbols, and the frequency domain range used for PDSCH transmission in each time slot is determined to be a first frequency domain range; the first frequency domain range is: the frequency domain range indicated by DCI for non-SBFD symbols.
[0182] In this embodiment, when the symbols used for PDSCH transmission in at least one time slot include non-SBFD symbols, the frequency domain ranges used for PDSCH transmission in all time slots may be uniformly determined as the first frequency domain range indicated by the DCI for non-SBFD symbols.
[0183] In this embodiment, by determining the frequency domain range used for PDSCH transmission in each time slot as the first frequency domain range, the frequency range used for receiving non-SBFD symbols and SBFD symbols is determined, so that the UE can receive PDSCH transmission at the correct position, thereby improving the reliability of PDSCH transmission. There is no need for signaling to separately indicate the frequency domain range of PDSCH transmission in the SBFD symbol. The implementation is simple, the complexity is low, and the signaling overhead is reduced.
[0184] In some embodiments, in the above step S102, determining the frequency domain range for PDSCH transmission on the symbol for PDSCH transmission in each time slot according to the DCI may include:
[0185] The symbols used for PDSCH transmission in at least one time slot include SBFD symbols, and the frequency domain range used for PDSCH transmission in each time slot is determined to be the second frequency domain range; the second frequency domain range is: the frequency domain range overlapping the first frequency domain range and the DL frequency domain range in the SBFD symbol.
[0186] In this embodiment, when the symbols used for PDSCH transmission in at least one time slot include SBFD symbols, the frequency domain range used for PDSCH transmission in all time slots can be uniformly determined as the second frequency domain range (for example, FD#2), that is, the frequency domain range used for PDSCH transmission in all time slots is the frequency domain range that overlaps with the first frequency domain range and the DL frequency domain range in the SBFD symbol.
[0187] 6f , the symbols used for PDSCH transmission in the DL time slot are non-SBFD symbols, and the symbols used for PDSCH transmission in the SBFD time slot are SBFD symbols. The frequency domain range used for PDSCH transmission in all time slots can be uniformly determined as FD#2.
[0188] In this embodiment, by determining the frequency domain range used for PDSCH transmission in each time slot as the second frequency domain range, the frequency range used for receiving non-SBFD symbols and SBFD symbols is determined, so that the UE can receive PDSCH transmission at the correct position, thereby improving the reliability of PDSCH transmission. There is no need for signaling to separately indicate the frequency domain range of PDSCH transmission in the SBFD symbol. The implementation is simple, the complexity is low, and the signaling overhead is reduced.
[0189] In some embodiments, the method further comprises:
[0190] For any time slot, when the frequency domain range used for PDSCH transmission in the time slot is determined to be the first frequency domain range, if the symbol used for PDSCH transmission in the time slot includes an SBFD symbol, and the first frequency domain range and the non-DL frequency domain range in the SBFD symbol have an overlapping frequency domain range, it is determined that the PDSCH in the time slot is not received.
[0191] Here, determining not to receive the PDSCH in the time slot may include determining to cancel receiving the PDSCH in the time slot.
[0192] In this embodiment, if the symbols used for PDSCH transmission in a certain time slot include SBFD symbols, and it is determined that the first frequency domain range used for PDSCH transmission in the time slot has an overlapping frequency domain range with the non-DL frequency domain range in the SBFD symbol, the PDSCH in the time slot is not received. This can be easily implemented, avoiding the additional complex design due to the need to ensure the performance of receiving PDSCH, and making up for the deficiency in the prior art of lacking a definition of whether the PDSCH transmission on the SBFD symbol is received.
[0193] 6g , if the frequency domain range for PDSCH transmission in a certain SBFD time slot is determined to be FD#1, when the symbols for PDSCH transmission in the SBFD time slot include SBFD symbols, the PDSCH in the SBFD time slot is not received.
[0194] In some embodiments, the first information includes an information field; the value of the information field is a first bit value, and the first information is used to indicate that the multiple PDSCH transmissions can use SBFD symbols and non-SBFD symbols, and any one of the multiple PDSCH transmissions can use SBFD symbols or non-SBFD symbols;
[0195] Alternatively, the value of the information field is the second bit value, and the first information is used to indicate that multiple PDSCH transmissions can use SBFD symbols and non-SBFD symbols, and any one PDSCH transmission in the multiple PDSCH transmissions can use SBFD symbols and non-SBFD symbols;
[0196] Alternatively, the value of the information field is the third bit value, and the first information is used to indicate that multiple PDSCH transmissions can use SBFD symbols, and any one of the multiple PDSCH transmissions can use SBFD symbols;
[0197] Alternatively, the value of the information field is the fourth bit value, and the first information is used to indicate that multiple PDSCH transmissions can use non-SBFD symbols, and any one PDSCH transmission among the multiple PDSCH transmissions can use non-SBFD symbols.
[0198] In some examples, the information field includes several bits, such as two bits.
[0199] In some examples, the first bit value is "00", or the second bit value is "01", or the third bit value is "10", or the fourth bit value is "11".
[0200] In this embodiment, the content indicated by the first information can be determined by the value of the information field of the first information. Different values enable the first information to clearly indicate the symbols that can be used for multiple PDSCH transmissions, as well as the symbols that can be used for any one of the multiple PDSCH transmissions. Since the symbols that can be used can be clearly determined, multiple PDSCH transmissions will be more reliable.
[0201] In some embodiments, the method further comprises at least one of the following:
[0202] The value of the information field is a first bit value. For any time slot, if the symbol where the PDSCH in the time slot is located includes at least one UL symbol or includes both SBFD and non-SBFD symbols, it is determined that the PDSCH in the time slot is not received;
[0203] The value of the information field is a second bit value. For any time slot, if the symbol where the PDSCH in the time slot is located includes at least one UL symbol, it is determined that the PDSCH in the time slot is not received;
[0204] The value of the information field is the third bit value. For any time slot, if the symbol where the PDSCH in the time slot is located includes at least one non-SBFD symbol, it is determined that the PDSCH in the time slot is not received.
[0205] The value of the information field is the fourth bit value. For any time slot, if the symbol where the PDSCH in the time slot is located includes at least one SBFD symbol or UL symbol, it is determined that the PDSCH in the time slot is not received.
[0206] In this embodiment, the multiple PDSCH transmissions indicated by the value of the information field of the first information and the symbols that can be used for any PDSCH transmission can be combined with the symbols where the PDSCH in each time slot is actually located to determine whether to receive the PDSCH in each time slot. This facilitates implementation and avoids the need for additional complex design to ensure the performance of receiving the PDSCH, and enables the UE to receive the PDSCH transmission at the correct location, thereby improving the reliability of the PDSCH transmission.
[0207] In some embodiments, the PDSCH in the plurality of time slots includes at least one of the following:
[0208] Repeated transmission of PDSCH;
[0209] SPS PDSCH without repeated transmission;
[0210] Multiple PDSCHs scheduled by a single DCI.
[0211] In some examples, the multiple PDSCHs are: multiple PDSCHs in one or more PDSCH sets that are repeatedly transmitted by the SPS PDSCH.
[0212] In this embodiment, the repeated transmission of each PDSCH can be called a group of PDSCHs. There are multiple groups of PDSCHs in the SPS PDSCH with repeated transmission. The symbol categories of the PDSCHs of different groups may be different. For example, the PDSCH of Group#1 is in a non-SBFD symbol, and the symbol where the PDSCH of Group#2 is located includes a SBFD symbol.
[0213] In some examples, for an SPS PDSCH with repeated transmission, multiple PDSCHs refer to multiple PDSCHs in a group.
[0214] 7 , for an SPS PDSCH with repeated transmission, one SPS PDSCH is repeatedly transmitted four times to form a group including PDSCH#0 to PDSCH#3. The symbol where PDSCH#0 is located is a non-SBFD symbol, and the symbols where PDSCH#1 to PDSCH#3 are transmitted are SBFD symbols.
[0215] In some other examples, for an SPS PDSCH with repeated transmission, the multiple PDSCHs refer to multiple PDSCHs in all groups.
[0216] In this embodiment, the PDSCHs in the multiple time slots indicated by the DCI may be PDSCHs with repeated transmission, SPS PDSCHs with non-repeated transmission, or multiple PDSCHs scheduled by a single DCI, thereby enabling the solution provided by the embodiment of the present disclosure to be suitable for different application scenarios.
[0217] This embodiment can be combined with any other embodiments without contradiction; any scheme (or optional scheme) in this embodiment can be combined with each other without contradiction; any scheme in this embodiment can be combined with any scheme in other embodiments without contradiction; the steps in this embodiment can be exchanged in order without contradiction.
[0218] The following information processing method is performed by a network device and is similar to the description of the information processing method performed by the terminal mentioned above; and, for technical details and technical effects not disclosed in the embodiment of the information processing method performed by the network device, please refer to the description of the example of the information processing method performed by the terminal, and no detailed description will be given here.
[0219] FIG8 is a flow chart of an information processing method according to an exemplary embodiment. The information processing method is executed by a network device. As shown in FIG8 , the information processing method may include the following steps:
[0220] S201: Send DCI; wherein the DCI is used to indicate multiple PDSCH transmissions in multiple time slots; wherein the symbols used for PDSCH transmission in each time slot include at least one of SBFD symbols and non-SBFD symbols; the frequency domain range used for PDSCH transmission in the SBFD symbol is the same as or different from the frequency domain range used for PDSCH transmission in the non-SBFD symbol.
[0221] In some examples, the information processing method can be performed by a network device, which can be a base station, and the base station can be a gNB.
[0222] In some examples, a network device sends DCI to a terminal, which may be a mobile terminal or a fixed terminal, including but not limited to a mobile phone, a wearable device, an Internet of Things device, etc.
[0223] In some examples, PDSCH transmission is used for transmission of downlink data, such as transmission of unicast data, paging signals, random access response messages, and other data.
[0224] In some examples, the multiple PDSCH transmissions indicated by the DCI may be multiple different PDSCH transmissions or multiple repeated transmissions of the same PDSCH.
[0225] In some examples, DCI is used to instruct the terminal to receive PDSCH in multiple time slots, for example, DCI is used to instruct the terminal to perform PDSCH repetition transmission in multiple time slots, SPS PDSCH with or without repetition transmission, or to instruct the terminal to receive multiple PDSCH transmissions scheduled by a single DCI.
[0226] In some examples, DCI may be used to indicate time domain resource information for PDSCH transmission.
[0227] For example, the time domain resource information includes information such as the time slot position, the starting symbol position within the time slot, and the time domain length. The time domain length can be used to indicate the number of consecutive symbols allocated to the PDSCH, counting from the starting symbol position.
[0228] For example, the time domain resource allocation information of the DCI includes a row index, and the row index is used by the terminal to search for time domain resource information for PDSCH transmission from a pre-configured time domain resource allocation table.
[0229] In some examples, the DCI may be used to indicate the symbol position occupied by the PDSCH within each of a plurality of slots.
[0230] In some examples, the symbols in a time slot may be all SBFD symbols, or all non-SBFD symbols, or may include both SBFD and non-SBFD symbols.
[0231] In some examples, an SBFD symbol is a symbol that includes both a DL subband and a UL subband in the frequency domain, and a non-SBFD symbol is a symbol that does not include both a DL subband and a UL subband in the frequency domain. For example, a non-SBFD symbol is a DL symbol, a UL symbol, or an F symbol.
[0232] In some examples, the DCI may indicate multiple PDSCH transmissions based on mini-slot scheduling. A mini-slot may consist of a portion of consecutive symbols within a time slot. For example, the length of a downlink mini-slot may be 2, 4, or 7 symbols, and the mini-slot may start at any symbol within a time slot.
[0233] In some examples, the network may notify the terminal of the symbols used for PDSCH transmission in multiple time slots through higher layer signaling or physical layer signaling. For example, the physical layer signaling includes DCI.
[0234] In some examples, symbols used for PDSCH transmission within multiple time slots include SBFD symbols and / or non-SBFD symbols.
[0235] For example, all symbols used for PDSCH transmission in a time slot are non-SBFD symbols; or, all symbols used for PDSCH transmission in a time slot are SBFD symbols; or, symbols used for PDSCH transmission in a time slot include SBFD symbols and non-SBFD symbols.
[0236] In some examples, the types of symbols used for PDSCH transmission in different time slots may be the same or different, for example, the symbols used for PDSCH transmission in time slot n are all non-SBFD symbols, the symbols used for PDSCH transmission in time slot n+1 are all SBFD symbols, and the symbols used for PDSCH transmission in time slot n+2 include SBFD symbols and non-SBFD symbols.
[0237] In some examples, the frequency domain range used for PDSCH transmission in SBFD symbols is the same as or different from the frequency domain range used for PDSCH transmission in non-SBFD symbols.
[0238] In some examples, the DCI may be used to indicate a frequency domain range used for PDSCH transmission in non-SBFD symbols. For example, the FDRA field in the DCI indicates that the frequency domain range used for PDSCH transmission in non-SBFD symbols is a first frequency domain range.
[0239] In some examples, the frequency domain range of the PDSCH transmission is used to indicate the frequency domain position occupied by the PDSCH transmission.
[0240] In some examples, the frequency domain range can be characterized by a resource grid, a bandwidth portion, a physical resource module, and / or a resource block.
[0241] In some examples, in an SBFD symbol, a frequency domain range that can be used for DL transmission is called a DL frequency domain range, and a frequency domain range that cannot be used for DL transmission is called a non-DL frequency domain range.
[0242] In some examples, the DL frequency domain range may be a frequency domain range where the DL subband overlaps with the BWP.
[0243] In other examples, the DL frequency domain range may be a frequency domain range where a DL subband and a GB overlap with a BWP.
[0244] In some examples, the frequency domain range used for PDSCH transmission in the SBFD symbol is the second frequency domain range, and the second frequency domain range can be a frequency domain range that overlaps the first frequency domain range indicated by the DCI and the DL frequency domain range in the SBFD symbol.
[0245] An embodiment of the present disclosure provides an information processing method, by sending DCI; wherein the DCI is used to indicate multiple PDSCH transmissions in multiple time slots; based on the DCI, a frequency domain range used for PDSCH transmission is determined on the symbol used for PDSCH transmission in each time slot; wherein the symbol includes at least one of an SBFD symbol and a non-SBFD symbol. In this way, the frequency domain ranges on the SBFD symbol and the non-SBFD symbol where the PDSCH transmission is located can be clearly determined, which can improve the reliability of the PDSCH transmission and can make up for the deficiency in the prior art in how to determine the frequency domain range of the PDSCH transmission in the SBFD symbol.
[0246] In some embodiments, the method may further include:

[0250] In this embodiment, by sending the first information, since the first information clearly indicates the categories of symbols that can be used for multiple PDSCH transmissions and at least one of the categories of symbols that can be used for any one of the multiple PDSCH transmissions, the category of symbols that can be used for PDSCH transmission can be clearly determined, which improves the reliability of executing multiple PDSCH transmissions compared to the case where the symbol category is uncertain.
[0251] In some embodiments, the first information is used to indicate at least one of the following:
[0252] Multiple PDSCH transmissions can use SBFD symbols and non-SBFD symbols, and any one of the multiple PDSCH transmissions can use SBFD symbols or non-SBFD symbols;

[0255] The multiple PDSCH transmissions can use non-SBFD symbols, and any one of the multiple PDSCH transmissions can use non-SBFD symbols.
[0256] In this embodiment, the first information clearly indicates symbols that can be used to perform multiple PDSCH transmissions and symbols that can be used to perform any one of the multiple PDSCH transmissions, so that the multiple PDSCH transmissions are more reliable.
[0257] In some embodiments, sending the first information may include:
[0258] The first information is sent through a first message; wherein the first message includes: at least one of a DCI message, an RRC message, a MAC-CE message, and a SIB message.
[0259] In some embodiments, the first information is sent to the terminal via a DCI message.
[0260] In some embodiments, the first information is sent to the terminal via an RRC message.
[0261] In some embodiments, the first information is sent to the terminal via a MAC CE message.
[0262] In some embodiments, the first information is sent to the terminal via a SIB1 message.
[0263] In this embodiment, the first information can be sent by reusing messages in the communication process, which can reduce signaling overhead, reduce resource consumption, and improve resource utilization efficiency.
[0264] In some embodiments, for any time slot, the symbol used for PDSCH transmission in the time slot is a non-SBFD symbol, and the frequency domain range used for PDSCH transmission in the time slot is a first frequency domain range; the first frequency domain range is: the frequency domain range indicated by the DCI for the non-SBFD symbol;
[0265] And / or, for any time slot, the symbols used for PDSCH transmission in the time slot are SBFD symbols, and the frequency domain range used for PDSCH transmission in the time slot is the target frequency domain range.
[0266] In some examples, the FDRA field in the DCI indicates that the frequency domain range used for PDSCH transmission in non-SBFD symbols is the first frequency domain range.
[0267] In some examples, the target frequency domain range may be the same as or different from the first frequency domain range.
[0268] In some embodiments, the target frequency domain range is a second frequency domain range, wherein the second frequency domain range is: a frequency domain range where the first frequency domain range overlaps with a DL frequency domain range in the SBFD symbol.
[0269] In this embodiment, for any time slot, if the symbol used for PDSCH transmission in the time slot is a non-SBFD symbol, the frequency domain range used for PDSCH transmission in the non-SBFD symbol of the time slot is determined to be the first frequency domain range (for example, FD#1); if the symbol used for PDSCH transmission in the time slot is a SBFD symbol, the frequency domain range used for PDSCH transmission in the SBFD symbol of the time slot can be determined to be the second frequency domain range (for example, FD#2).
[0270] In some examples, for any time slot, the symbols used for PDSCH transmission in the time slot are only SBFD symbols or non-SBFD symbols. The frequency domain range used for PDSCH transmission in non-SBFD symbols is a first frequency domain range, and the frequency domain range used for PDSCH transmission in SBFD symbols is a second frequency domain range.
[0271] In other examples, the symbols used for PDSCH transmission in a time slot include SBFD symbols or non-SBFD symbols. The frequency domain range used for PDSCH transmission in the non-SBFD symbols is a first frequency domain range, and the frequency domain range used for PDSCH transmission in the SBFD symbols is a second frequency domain range.
[0272] In some embodiments, the target frequency domain range is a third frequency domain range, wherein the third frequency domain range is: a frequency domain range indicated by the DCI for the SBFD symbol.
[0273] In this embodiment, for any time slot, if the symbol used for PDSCH transmission in the time slot is a non-SBFD symbol, the frequency domain range used for PDSCH transmission in the non-SBFD symbol of the time slot is determined to be the first frequency domain range (for example, FD#1); if the symbol used for PDSCH transmission in the time slot is a SBFD symbol, the frequency domain range used for PDSCH transmission in the SBFD symbol of the time slot can be determined to be the third frequency domain range (for example, FD#3).
[0274] For example, DCI includes two sets of FDRA, and the two sets of FDRA respectively indicate FD#1 and FD#3, where FD#1 is used for non-SBFD symbols and FD#3 is used for SBFD symbols.
[0275] In some embodiments, if the DCI indicates a third frequency domain range for the SBFD symbol, the priority of using the third frequency domain range is higher than the priority of using the second frequency domain range.
[0276] In some embodiments, when a first condition is met, the target frequency domain range is a fourth frequency domain range; wherein the first condition includes: a bandwidth used for DL transmission in the SBFD symbol is greater than or equal to a bandwidth of the first frequency domain range.
[0277] In this embodiment, for any time slot, if the symbol used for PDSCH transmission in the time slot is a non-SBFD symbol, the frequency domain range used for PDSCH transmission in the non-SBFD symbol of the time slot is determined to be the first frequency domain range (for example, FD#1); if the symbol used for PDSCH transmission in the time slot is an SBFD symbol, when the first condition is met, the frequency domain range used for PDSCH transmission in the SBFD symbol of the time slot can be determined to be the fourth frequency domain range (for example, FD#4). In this way, FD adaptation of PDSCH on SBFD symbols and non-SBFD symbols can be achieved.
[0278] In some embodiments, the number of RBs included in the fourth frequency domain range is equal to the number of RBs included in the first frequency domain range, and the fourth frequency domain range is a frequency domain range that overlaps the fifth frequency domain range with the frequency domain range used for DL transmission in the SBFD symbol; wherein, the starting RB of the fifth frequency domain range is the starting RB in the BWP, or the ending RB of the fifth frequency domain range is the ending RB in the BWP.
[0279] In some examples, the fourth frequency domain range may be the same as the fifth frequency domain range.
[0280] In other examples, the fourth frequency domain range may be different from the fifth frequency domain range.
[0281] In some examples, if the DCI indicates a third frequency domain range for the SBFD symbol, the priority of using the third frequency domain range is higher than the priority of using the fourth frequency domain range.
[0282] In some embodiments, the symbols used for PDSCH transmission in at least one time slot include non-SBFD symbols, and the frequency domain range used for PDSCH transmission in each time slot is a first frequency domain range; the first frequency domain range is: the frequency domain range indicated by DCI for non-SBFD symbols.
[0283] In this embodiment, when the symbols used for PDSCH transmission in at least one time slot include non-SBFD symbols, the frequency domain ranges used for PDSCH transmission in all time slots may be uniformly determined as the first frequency domain range indicated by the DCI for non-SBFD symbols.
[0284] In some embodiments, the symbols used for PDSCH transmission in at least one time slot include SBFD symbols, and the frequency domain range used for PDSCH transmission in each time slot is a second frequency domain range; the second frequency domain range is: a frequency domain range that overlaps the first frequency domain range with the downlink DL frequency domain range in the SBFD symbol.
[0285] In this embodiment, when the symbols used for PDSCH transmission in at least one time slot include SBFD symbols, the frequency domain range used for PDSCH transmission in all time slots can be uniformly determined as the second frequency domain range (for example, FD#2), that is, the frequency domain range used for PDSCH transmission in all time slots is the frequency domain range that overlaps with the first frequency domain range and the DL frequency domain range in the SBFD symbol.
[0286] In some embodiments, the first information includes an information field; the value of the information field is a first bit value, and the first information is used to indicate that the multiple PDSCH transmissions can use SBFD symbols and non-SBFD symbols, and any one of the multiple PDSCH transmissions can use SBFD symbols or non-SBFD symbols;
[0287] Alternatively, the value of the information field is the second bit value, and the first information is used to indicate that multiple PDSCH transmissions can use SBFD symbols and non-SBFD symbols, and any one PDSCH transmission in the multiple PDSCH transmissions can use SBFD symbols and non-SBFD symbols;
[0288] Alternatively, the value of the information field is the third bit value, and the first information is used to indicate that multiple PDSCH transmissions can use SBFD symbols, and any one of the multiple PDSCH transmissions can use SBFD symbols;
[0289] Alternatively, the value of the information field is the fourth bit value, and the first information is used to indicate that multiple PDSCH transmissions can use non-SBFD symbols, and any one PDSCH transmission among the multiple PDSCH transmissions can use non-SBFD symbols.
[0290] In some examples, the information field includes several bits, such as two bits.
[0291] In some examples, the first bit value is "00", or the second bit value is "01", or the third bit value is "10", or the fourth bit value is "11".
[0292] In this embodiment, the content indicated by the first information can be determined by the value of the information field of the first information. Different values enable the first information to clearly indicate the symbols that can be used for multiple PDSCH transmissions, as well as the symbols that can be used for any one of the multiple PDSCH transmissions. Since the symbols that can be used can be clearly determined, multiple PDSCH transmissions will be more reliable.
[0293] In some embodiments, the PDSCH in the plurality of time slots includes at least one of the following:
[0294] Repeated transmission of PDSCH;
[0295] SPS PDSCH without repeated transmission;
[0296] Multiple PDSCHs scheduled by a single DCI.
[0297] In some examples, the multiple PDSCHs are: multiple PDSCHs in one or more PDSCH sets that are repeatedly transmitted by the SPS PDSCH.
[0298] In this embodiment, the repeated transmission of each PDSCH can be called a group of PDSCHs. There are multiple groups of PDSCHs in the SPS PDSCH with repeated transmission. The symbol categories of the PDSCHs of different groups may be different. For example, the PDSCH of Group#1 is in a non-SBFD symbol, and the symbol where the PDSCH of Group#2 is located includes a SBFD symbol.
[0299] In some examples, for an SPS PDSCH with repeated transmission, multiple PDSCHs refer to multiple PDSCHs in a group.
[0300] In some other examples, for an SPS PDSCH with repeated transmission, the multiple PDSCHs refer to multiple PDSCHs in all groups.
[0301] In this embodiment, the PDSCHs in the multiple time slots indicated by the DCI may be PDSCHs with repeated transmission, SPS PDSCHs with non-repeated transmission, or multiple PDSCHs scheduled by a single DCI, thereby enabling the solution provided by the embodiment of the present disclosure to be suitable for different application scenarios.
[0302] This embodiment can be combined with any other embodiments without contradiction; any scheme (or optional scheme) in this embodiment can be combined with each other without contradiction; any scheme in this embodiment can be combined with any scheme in other embodiments without contradiction; the steps in this embodiment can be exchanged in order without contradiction.
[0303] In order to further explain any embodiment of the present disclosure, several specific embodiments are provided below.
[0304] Figure 9 is an interactive diagram illustrating an information processing method according to an embodiment of the present disclosure. As shown in Figure 9, the information processing method may include the following steps:
[0305] Step S301: The base station sends first information to indicate multiple PDSCH transmissions and symbols that can be used by any of the PDSCH transmissions.
[0306] In some embodiments, the UE receives first information, where the first information indicates multiple PDSCH transmissions and symbols that can be used by any of the PDSCH transmissions when one DCI indicates multiple PDSCH transmissions.
[0307] Step S302: The base station sends a DCI to indicate multiple PDSCH transmissions.
[0308] In some embodiments, the UE receives DCI indicating multiple PDSCH transmissions.
[0309] Step S303: The UE determines the frequency domain range of multiple PDSCH transmissions indicated by a DCI.
[0310] The frequency domain range indicated by the Frequency Domain Resource Allocation (FDRA) field in the DCI in non-SBFD symbols is FD#1. In SBFD symbols, the frequency domain range available for DL transmission is called the DL frequency domain range, while the frequency domain range unavailable for DL transmission is called the non-DL frequency domain range. FD#2 is the frequency domain range where FD#1 overlaps with the DL frequency domain range.
[0311] In some examples, the DL frequency domain range is a frequency domain range where the DL subband overlaps with the BWP.
[0312] In other examples, the DL frequency domain range is a frequency domain range where the DL subband and the GB overlap with the BWP.
[0313] In some examples, the UE determines the frequency domain range used by multiple PDSCHs scheduled by a DCI on SBFD and non-SBFD symbols.
[0314] In some examples, the UE determines the frequency domain range used by multiple PDSCHs scheduled by a DCI on SBFD or non-SBFD symbols.
[0315] In some embodiments, the first information indicates at least one of the following:
[0316] Multiple PDSCH transmissions can occur simultaneously in SBFD and non-SBFD symbols, and any one PDSCH transmission can occur only in SBFD or non-SBFD symbols.
[0317] Multiple PDSCH transmissions can occur simultaneously in SBFD and non-SBFD symbols, and any one PDSCH transmission can occur simultaneously in SBFD and non-SBFD symbols.

[0323] Solution 3-3: Among the multiple PDSCH symbols indicated by the DCI, at least one symbol is SBFD. In all time slots, the FD of the PDSCH uses FD#2.
[0324] Solution 3-4: DCI includes two sets of FDRA, indicating FD#1 and FD#3, which are used for non-SBFD symbols and SBFD symbols respectively.
[0325] In a time slot, if the symbol where the PDSCH is located is non-SBFD, FD uses FD#1; if the symbol where the PDSCH is located is a SBFD symbol, FD uses FD#3.
[0326] Scheme 3-5: FD adaptation of PDSCH on SBFD symbols and non-SBFD symbols.
[0327] In a time slot, if the symbol where the PDSCH is located is non-SBFD, FD uses FD#1. If the symbol where the PDSCH is located is a SBFD symbol and condition 0 is met, FD uses FD#4.
[0328] In some examples, condition 0: the bandwidth available for DL transmission in the SBFD symbol is greater than or equal to the bandwidth of FD#1.
[0329] In some examples, the number of RBs included in FD#4 used by the SBFD symbol is equal to the number of RBs in FD#1, and FD#4 is the portion where FD#1-1 overlaps with the frequency domain range available for DL transmission.
[0330] In some examples, the FD#1-1 starting RB is the starting RB in the BWP.
[0331] In some examples, the end RB of FD#1-1 is the end RB in the BWP.
[0332] In some examples, in a time slot, the symbol where the PDSCH is located has an SBFD symbol, which does not meet condition 0, and the PDSCH is not received.

[0338] Solution 3-6: PDSCH uses FD#2. In a time slot, the symbol where the PDSCH is located includes at least one non-SBFD symbol, and the PDSCH in the time slot is not received.
[0339] In some embodiments, the first information indicates that multiple PDSCH transmissions are only in non-SBFD symbols, and any PDSCH transmission can only be in non-SBFD symbols, and schemes 3-7 are performed.
[0340] Solution 3-7: PDSCH uses FD#1. In a time slot, the symbol where the PDSCH is located includes at least one SBFD symbol or UL symbol, and the PDSCH in the time slot is not received.
[0341] The information processing method provided by the embodiments of the present disclosure can be applied to scenarios of repeated PDSCH transmission, SPS PDSCH without repeated transmission, or multiple PDSCHs scheduled by a single DCI.
[0342] For SPS PDSCH with repeated transmission, the repetition of each PDSCH can be called a group PDSCH. There are multiple groups of PDSCH in SPS PDSCH with repetition. The symbol categories of PDSCHs in different groups may be different. For example, the PDSCH of Group#1 is in non-SBFD symbols, and the PDSCH of Group#2 includes SBFD symbols.
[0343] Option 1: For SPS PDSCH with repeated transmission, multiple PDSCHs refer to multiple PDSCHs in one group.
[0344] Option 2: For SPS PDSCH with repeated transmission, multiple PDSCHs refer to multiple PDSCHs in all groups.
[0345] Under the conditions of Option 1 or Option 2, one or more of the above-mentioned Schemes 3-1, 3-2, 3-3, 3-4, 3-5, 3-6 and 3-7 are used.
[0346] In some embodiments, the execution steps on the base station side refer to the relevant description content on the terminal side and will not be repeated here.
[0347] In the examples of the present disclosure, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other examples, or with optional implementations in other embodiments.
