[0039] Figure 1 This is a schematic diagram illustrating an application scenario according to an embodiment of the present disclosure.

[0040] like Figure 1 As shown, the embodiments of this disclosure can be applied to scenarios where terminals communicate with network devices, but are not limited to this scenario. Figure 1 The entities shown are illustrative; the implementation methods or embodiments of this disclosure may include... Figure 1 All or part of the main body, or may include Figure 1 Other entities besides these, the number of each entity is arbitrary, not limited to Figure 1 . Figure 1 The connections shown are illustrative. Any entities may be connected or not connected, and the connection can be in any way, whether it is a direct or indirect connection, a wired connection or a wireless connection.

[0041] The terminals in this disclosure include, but are not limited to, communication devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices. The terminals can communicate with network devices, including but not limited to network devices in 4G, 5G, and 6G communication systems, such as base stations and core networks.

[0042] In one embodiment, the network device can configure a subband for the terminal, for example, it can configure an uplink subband for the terminal in a time slot, or it can configure a downlink subband for the terminal in a time slot.

[0043] It should be noted that the full name of the uplink involved in the embodiments of this disclosure can be uplink (UL), and the full name of the downlink involved can be downlink (DL).

[0044] The time slots configured with uplink subbands include at least one of the following: downlink time slots, flexible time slots, and uplink time slots. The time slots configured with downlink subbands include at least one of the following: uplink time slots, flexible time slots, and downlink time slots.

[0045] Network devices can perform full-duplex communication in time slots configured with uplink subbands and downlink subbands. Therefore, time slots configured with uplink and downlink subbands can also be called Subband Full Duplex (SBFD) time slots. Correspondingly, time slots without configured subbands can be called non-SBFD time slots. A terminal can be a terminal capable of half-duplex communication in an SBFD time slot. For example, in an SBFD time slot, a terminal can perform uplink transmission but cannot receive downlink transmission, or it can receive downlink transmission but cannot perform uplink transmission. A symbol that includes both uplink and downlink subbands in the frequency domain can be called an SBFD symbol. Optionally, when some symbols in a time slot are configured as SBFD symbols, that time slot can be called an SBFD time slot. Optionally, when all symbols in a time slot are configured as SBFD symbols, that time slot can be called an SBFD time slot.

[0046] Figure 2 This is a schematic diagram of an SBFD time slot according to an embodiment of the present disclosure.

[0047] Taking the SBFD time slot, which includes a time slot configured with an uplink subband, as an example. Figure 2 As shown, in slots #0 to #4 of the five time slots, the network device configures uplink subbands for the terminal in slots #1 to #3. Therefore, slots #1 to #3 can be called SBFD time slots; slot #0 is the downlink time slot, and slot #4 is the uplink time slot. Slots #0 and #4 can be called non-SBFD time slots.

[0048] In the frequency domain resources corresponding to the time slots configured with uplink sub-bands, the downlink resources other than the uplink sub-bands can be called downlink sub-bands. A guard band (GB) can be set between the uplink sub-bands and the downlink sub-bands to isolate them in the frequency domain.

[0049] When a network device transmits PDSCH to a terminal in multiple time slots, some PDSCHs are located in non-SBFD time slots and some PDSCHs are located in SBFD time slots. In this case, there may be a conflict between the first frequency domain resource configured for the PDSCH and the uplink subband in the SBFD time slot.

[0050] In the multiple symbols included in the SBFD time slot, the uplink subband can be configured on all or some of the symbols. Symbols configured with subbands (e.g., uplink subbands) can be called SBFD symbols, and symbols not configured with subbands (e.g., uplink subbands) can be called non-SBFD symbols. The first frequency domain resource configured by PDSCH conflicts with the uplink subband in the SBFD time slot. Specifically, the first frequency domain resource configured by PDSCH in the SBFD time slot conflicts with the uplink subband in the SBFD symbol.

[0051] When the first frequency domain resource configured for PDSCH conflicts with the uplink subband in an SBFD symbol, in some cases, the terminal determines that it can receive PDSCH on the SBFD symbol, while the network device determines that the terminal cannot receive PDSCH on the SBFD symbol; conversely, the terminal determines that it cannot receive PDSCH on the SBFD symbol, but the network device determines that the terminal can receive PDSCH on the SBFD symbol. It is evident that the terminal and the network device may have different understandings regarding whether the terminal can receive PDSCH on the SBFD symbol, which can affect the direct communication between the terminal and the network device. Therefore, it is necessary to clarify on which type of symbols the terminal can receive PDSCH.

[0052] The symbols used in this embodiment may include OFDM (Orthogonal Frequency Division Multiplexing) symbols.

[0053] Figure 3 This is a schematic flowchart illustrating a reception determination method according to an embodiment of the present disclosure. The reception determination method shown in this embodiment can be executed by a terminal.

[0054] like Figure 3 As shown, the receiving determination method may include the following steps:

[0055] In step S301, symbols that can be used to receive the Physical Downlink Shared Channel (PDSCH) transmitted in multiple time slots are determined based on the first information sent by the network device, wherein the symbols include at least one of the following: sub-band full-duplex (SBFD) symbols and non-SBFD symbols.

[0056] It should be noted that, Figure 3 The embodiments shown can be implemented independently or in combination with at least one other embodiment of this disclosure. The specific choice can be made as needed, and this disclosure does not limit the scope of the embodiments.

[0057] In one embodiment, the terminal can receive first information sent by the network device, and then determine, based on the first information, the symbols that can be used to receive PDSCH transmitted in multiple time slots. For example, it can be determined that PDSCH transmitted in multiple time slots can only be received on SBFD symbols, or that PDSCH transmitted in multiple time slots can only be received on non-SBFD symbols, or that PDSCH transmitted in multiple time slots can be received on both SBFD and non-SBFD symbols. Accordingly, it can be ensured that the symbols determined by the terminal that can be used to receive PDSCH transmitted in multiple time slots are consistent with the understanding of the network device, which is beneficial for ensuring the communication quality between the network device and the terminal.

[0058] It should be noted that the embodiments disclosed herein are mainly exemplified when the SBFD symbol is a symbol configured with an uplink subband. However, the technical solutions disclosed herein can also be applied to the case where the SBFD symbol is a symbol configured with a downlink subband.

[0059] In one embodiment, the PDSCH transmitted in multiple time slots includes at least one of the following:

[0060] PDSCH repetition;

[0061] Semi-Persistent Scheduling (SPS) PDSCH;

[0062] Multiple PDSCHs scheduled by a single Downlink Control Information (DCI) can be referred to as Multiple PDSCH scheduled by a single DCI.

[0063] SPS PDSCH can further include SPS PDSCH with repetition and SPS PDSCH without repetition.

[0064] For SPS PDSCH with repetition, network devices can send multiple PDSCHs in SPS resources. Each PDSCH can be repeatedly transmitted. The repeated transmission of a PDSCH can be called a group. In this embodiment, the PDSCH transmitted in multiple time slots can include the PDSCH in one group in SPS PDSCH with repetition, or it can include the PDSCH in all groups in SPS PDSCH with repetition.

[0065] In one embodiment, the first information includes at least one of the following: frequency domain resource information; an indication field.

[0066] The network device indicates the terminal via a first information instruction that it is capable of receiving symbols of DSCH transmitted in multiple time slots, and the indication method includes, but is not limited to, explicit indication and implicit indication.

[0067] For example, when using an explicit indication method, the first information sent by the network device may include an indication field. This indication field can be a newly added field in the signaling or a field already present in the multiplexed signaling (e.g., a field composed of reserved bits). The signaling includes at least one of the following: Radio Resource Control (RRC) signaling, DCI, or Media Access Control (MAC) control element (CE). Based on the indication field received in the signaling, the terminal can determine the symbols indicated by the network device that are sufficient to receive PDSCH symbols transmitted in multiple time slots.

[0068] For example, when using the implicit indication method, the first information sent by the network device may include frequency domain resource information. The terminal can determine the frequency domain resources configured for the PDSCH transmitted in multiple time slots based on the frequency domain resource information. Then, based on the relationship between the frequency domain resources configured for the PDSCH transmitted in multiple time slots and the downlink resources corresponding to the SBFD symbols, the terminal can determine the symbols indicated by the network device that are sufficient to receive the PDSCH transmitted in multiple time slots.

[0069] It should be noted that the downlink resources corresponding to the SBFD symbols in this embodiment may include downlink subbands, or may include downlink subbands and guard bands.

[0070] In one embodiment, determining symbols that can be used to receive PDSCH transmitted in multiple time slots based on first information sent by the network device includes at least one of the following:

[0071] When the frequency domain resource information sent by the network device configures the frequency domain resources of the PDSCH to be within the downlink resources corresponding to the SBFD symbol, it is determined that the PDSCH transmitted in multiple time slots can be received in both SBFD and non-SBFD symbols.

[0072] When the frequency domain resource information sent by the network device configures the frequency domain resources of the PDSCH to include frequency domain resources other than the downlink resources corresponding to the SBFD symbols, it is determined that the PDSCH transmitted in multiple time slots can only be received on SBFD symbols or non-SBFD symbols.

[0073] Figure 4AThis is a schematic diagram illustrating a frequency domain resource according to an embodiment of the present disclosure. Figure 4B This is a schematic diagram illustrating another frequency domain resource according to an embodiment of the present disclosure.

[0074] Taking a time slot containing 14 symbols as an example, uplink subbands are configured on symbols #6 to #10. The symbols that PDSCH needs to occupy in the SBFD time slot include symbols #3 to #8. Among them, symbols #3 to #5 are not configured with uplink subbands and are non-SBFD symbols, while symbols #6 to #8 are SBFD symbols.

[0075] like Figure 4A As shown, the network device configures the frequency domain resource of the PDSCH transmitted in multiple time slots as FD#1. FD#1 is within the downlink resources (e.g., downlink subband or downlink subband and guard band) corresponding to the SBFD symbol. Based on the frequency domain resource information, the terminal can determine that the frequency domain resource configured for the PDSCH transmitted in multiple time slots is FD#1. When the terminal determines that FD#1 is within the downlink resources corresponding to the SBFD symbol, it can determine that the network device instructs the terminal to receive the PDSCH transmitted in multiple time slots on both SBFD and non-SBFD symbols. For example, it can determine that the network device instructs the terminal to receive the PDSCH transmitted in multiple time slots on symbols #3 to #8.

[0076] like Figure 4B As shown, the network device configures the frequency domain resource of the PDSCH transmitted in multiple time slots as FD#1. FD#1 contains frequency domain resources other than the downlink resources corresponding to the SBFD symbol. The terminal can determine that the frequency domain resource configured for the PDSCH transmitted in multiple time slots is FD#1 based on the frequency domain resource information. When the terminal determines that FD#1 contains frequency domain resources other than the downlink resources corresponding to the SBFD symbol (e.g., ...), ... Figure 4B If there is a resource conflict between FD#1 and frequency domain resources other than downlink resources, it can be determined that the network device instructs the terminal to receive PDSCH transmitted in multiple time slots only on non-SBFD symbols, for example, to receive PDSCH transmitted in multiple time slots only on non-SBFD symbols (symbols #3 to #5).

[0077] It should be noted that when FD#1 contains frequency domain resources other than those located in the downlink resources corresponding to the SBFD symbol, the terminal can also determine that the network device instructs the terminal to receive PDSCHs transmitted in multiple time slots only in the SBFD symbol. For example, if the symbol containing the first PDSCH in multiple time slots includes the SBFD symbol, the terminal can determine that it can receive PDSCHs transmitted in multiple time slots only in the SBFD symbol; or, if the symbols containing the first PDSCH in multiple time slots are all SBFD symbols, the terminal can determine that it can receive PDSCHs transmitted in multiple time slots only in the SBFD symbol. Here, the first PDSCH refers to the PDSCH transmitted in the first time slot of the multiple time slots.

[0078] In one embodiment, determining that PDSCH transmitted in multiple time slots can only be received on SBFD symbols or non-SBFD symbols includes at least one of the following:

[0079] The symbol containing the first PDSCH in a PDSCH transmitted in multiple time slots includes the SBFD symbol, which determines that PDSCHs transmitted in multiple time slots can only be received on the SBFD symbol;

[0080] If the first PDSCH in a PDSCH transmitted across multiple time slots is located on a symbol that is not a SBFD symbol, it is determined that the PDSCH transmitted across multiple time slots can only be received on a non-SBFD symbol.

[0081] For example, a terminal can determine the time slot of the first PDSCH transmitted in multiple time slots, and determine the symbol in that time slot where the first PDSCH is located. If the symbol in that time slot where the first PDSCH is located includes an SBFD symbol, the terminal can determine that it can only receive PDSCH transmitted in multiple time slots on SBFD symbols; if the symbols in that time slot where the first PDSCH is located are all non-SBFD symbols, the terminal can determine that it can only receive PDSCH transmitted in multiple time slots on non-SBFD symbols.

[0082] In one embodiment, determining that PDSCH transmitted in multiple time slots can only be received on SBFD symbols or non-SBFD symbols includes at least one of the following:

[0083] The first PDSCH in a PDSCH transmitted in multiple time slots is a symbol that is entirely an SBFD symbol, which means that PDSCHs transmitted in multiple time slots can only be received on SBFD symbols.

[0084] If the symbol containing the first PDSCH in a PDSCH transmitted in multiple time slots includes a non-SBFD symbol, it is determined that the PDSCH transmitted in multiple time slots can only be received on a non-SBFD symbol.

[0085] For example, a terminal can determine the time slot of the first PDSCH transmitted in multiple time slots, and determine the symbol in that time slot where the first PDSCH is located. If all the symbols in that time slot where the first PDSCH is located are SBFD symbols, the terminal can determine that it can only receive PDSCH transmitted in multiple time slots on SBFD symbols; if the symbols in that time slot where the first PDSCH is located include non-SBFD symbols, the terminal can determine that it can only receive PDSCH transmitted in multiple time slots on non-SBFD symbols.

[0086] It should be noted that the number of time slots in which PDSCH is located shown in the attached figure is only a local example, and PDSCH can also be transmitted in time slots other than those shown in the attached figure.

[0087] Figure 5 This is a schematic flowchart illustrating another reception determination method according to an embodiment of the present disclosure. The reception determination method shown in this embodiment can be executed by a terminal. Figure 5 As shown, symbols that can be used to receive PDSCH transmitted in multiple time slots are determined based on the first information sent by the network device, including:

[0088] In step S501, when frequency domain resources for receiving PDSCH on SBFD symbols and frequency domain resources for receiving PDSCH on non-SBFD symbols are configured, it is determined that PDSCH transmitted in multiple time slots can be received on both SBFD and non-SBFD symbols.

[0089] It should be noted that, Figure 5 The embodiments shown can be implemented independently or in combination with at least one other embodiment of this disclosure. The specific choice can be made as needed, and this disclosure does not limit the scope of the embodiments.

[0090] In one embodiment, the first information sent by the network device may include frequency domain resource information, which may be configured with frequency domain resources for receiving PDSCH on SBFD symbols and frequency domain resources for receiving PDSCH on non-SBFD symbols. The frequency domain resources for receiving PDSCH on SBFD symbols do not include frequency domain resources located outside the downlink resources corresponding to the SBFD symbols.

[0091] In this case, the terminal can determine, based on the frequency domain resource information, that the frequency domain resources configured for receiving PDSCH on SBFD symbols and the frequency domain resources configured for receiving PDSCH on non-SBFD symbols, and thus determine that it can receive PDSCH transmitted in multiple time slots on both SBFD and non-SBFD symbols.

[0092] For example, in a non-SBFD symbol, PDSCH can be received on the frequency domain resources used for receiving PDSCH on the non-SBFD symbol, while in an SBFD symbol, PDSCH can be received on the frequency domain resources used for receiving PDSCH on the SBFD symbol.

[0093] In one embodiment, the indicator field occupies 1 bit or 2 bits. It should be noted that the number of bits occupied by the indicator field is not limited to 1 or 2; it can also be other numbers. The following embodiments mainly illustrate the technical solutions of this disclosure for the cases where the indicator field occupies 1 bit and 2 bits.

[0094] In one embodiment, determining symbols that can be used to receive PDSCH transmitted in multiple time slots based on first information sent by the network device includes at least one of the following:

[0095] When the indication field indicates that PDSCH transmitted in multiple time slots can be received on both SBFD and non-SBFD symbols, it is determined that PDSCH transmitted in multiple time slots can be received on both SBFD and non-SBFD symbols.

[0096] When the indication field indicates that PDSCH transmitted in multiple time slots can only be received on SBFD symbols or non-SBFD symbols, it is determined that PDSCH transmitted in multiple time slots can only be received on SBFD symbols or non-SBFD symbols.

[0097] In one embodiment, when the indication field occupies 1 bit, the indication field can indicate whether PDSCH transmitted in multiple time slots can be received on SBFD symbols and non-SBFD symbols, or whether PDSCH transmitted in multiple time slots can only be received on SBFD symbols or non-SBFD symbols.

[0098] For example, when the value of the 1 bit in the indication field is 1, it indicates that PDSCH transmitted in multiple time slots can be received on both SBFD and non-SBFD symbols. When the terminal determines that the value of the 1 bit in the indication field is 1, it can determine that it can receive PDSCH transmitted in multiple time slots on both SBFD and non-SBFD symbols.

[0099] For example, when the value of the 1 bit in the indication field is 0, PDSCH transmitted in multiple time slots can only be received on SBFD symbols or non-SBFD symbols. When the terminal determines that the value of the 1 bit in the indication field is 0, it can determine that PDSCH transmitted in multiple time slots can only be received on SBFD symbols or non-SBFD symbols.

[0100] In one embodiment, determining that PDSCH transmitted in multiple time slots can only be received on SBFD symbols or non-SBFD symbols includes at least one of the following:

[0101] The symbol containing the first PDSCH in a PDSCH transmitted in multiple time slots includes the SBFD symbol, which determines that PDSCHs transmitted in multiple time slots can only be received on the SBFD symbol;

[0102] If the first PDSCH in a PDSCH transmitted across multiple time slots is located on a symbol that is not a SBFD symbol, it is determined that the PDSCH transmitted across multiple time slots can only be received on a non-SBFD symbol.

[0103] For example, a terminal can determine the time slot of the first PDSCH transmitted in multiple time slots, and determine the symbol in that time slot where the first PDSCH is located. If the symbol in that time slot where the first PDSCH is located includes an SBFD symbol, the terminal can determine that it can only receive PDSCH transmitted in multiple time slots on SBFD symbols; if the symbols in that time slot where the first PDSCH is located are all non-SBFD symbols, the terminal can determine that it can only receive PDSCH transmitted in multiple time slots on non-SBFD symbols.

[0104] In one embodiment, determining that PDSCH transmitted in multiple time slots can only be received on SBFD symbols or non-SBFD symbols includes at least one of the following:

[0105] The first PDSCH in a PDSCH transmitted in multiple time slots is a symbol that is entirely an SBFD symbol, which means that PDSCHs transmitted in multiple time slots can only be received on SBFD symbols.

[0106] If the symbol containing the first PDSCH in a PDSCH transmitted in multiple time slots includes a non-SBFD symbol, it is determined that the PDSCH transmitted in multiple time slots can only be received on a non-SBFD symbol.

[0107] For example, a terminal can determine the time slot of the first PDSCH transmitted in multiple time slots, and determine the symbol in that time slot where the first PDSCH is located. If all the symbols in that time slot where the first PDSCH is located are SBFD symbols, the terminal can determine that it can only receive PDSCH transmitted in multiple time slots on SBFD symbols; if the symbols in that time slot where the first PDSCH is located include non-SBFD symbols, the terminal can determine that it can only receive PDSCH transmitted in multiple time slots on non-SBFD symbols.

[0108] In one embodiment, determining that PDSCH transmitted in multiple time slots can only be received on SBFD symbols or non-SBFD symbols includes at least one of the following:

[0109] The first PDSCH in a PDSCH transmitted in multiple time slots is a symbol that is entirely an SBFD symbol, which means that PDSCHs transmitted in multiple time slots can only be received on SBFD symbols.

[0110] If the first PDSCH in a PDSCH transmitted across multiple time slots is located on a symbol that is not a SBFD symbol, it is determined that the PDSCH transmitted across multiple time slots can only be received on a non-SBFD symbol.

[0111] For example, a terminal can determine the time slot of the first PDSCH transmitted in multiple time slots, and determine the symbol in that time slot where the first PDSCH is located. If all the symbols in that time slot where the first PDSCH is located are SBFD symbols, the terminal can determine that it can only receive PDSCH transmitted in multiple time slots on SBFD symbols; if all the symbols in that time slot where the first PDSCH is located are non-SBFD symbols, the terminal can determine that it can only receive PDSCH transmitted in multiple time slots on non-SBFD symbols.

[0112] In one embodiment, determining symbols that can be used to receive PDSCH transmitted in multiple time slots based on first information sent by the network device includes at least one of the following:

[0113] When the indication field takes the first value, the second value, or the indication field is empty, it indicates that PDSCH transmitted in multiple time slots can only be received on the SBFD symbol, thus determining that PDSCH transmitted in multiple time slots can only be received on the SBFD symbol.

[0114] When the indication field takes the first value, the second value, or the indication field is empty, it indicates that PDSCH transmitted in multiple time slots can only be received on non-SBFD symbols, thus determining that PDSCH transmitted in multiple time slots can only be received on non-SBFD symbols.

[0115] When the indication field takes the first value, the second value, or the field is empty, it indicates that PDSCH transmitted in multiple time slots can be received on both SBFD and non-SBFD symbols.

[0116] It is understood that the content indicated by the first information differs depending on whether the indicator field takes a first value, a second value, or is empty. The following examples illustrate the content indicated by the first information when the indicator field takes a first value, a second value, or is empty. However, the correspondence between the content indicated by the first information and the indicator field taking a first value, a second value, or being empty is not limited to the following examples.

[0117] In one embodiment, when the indication field occupies 1 bit, the indication field can indicate that PDSCH transmitted in multiple time slots can only be received on SBFD symbols, or that PDSCH transmitted in multiple time slots can only be received on non-SBFD symbols. When the indication field is empty, it can indicate that PDSCH transmitted in multiple time slots can be received on both SBFD symbols and non-SBFD symbols.

[0118] For example, when the value of the 1 bit in the indication field is 1, it indicates that PDSCH transmitted in multiple time slots can only be received on SBFD symbols. When the terminal determines that the value of the 1 bit in the indication field is 1, it can determine that it can only receive PDSCH transmitted in multiple time slots on SBFD symbols.

[0119] For example, when the value of the 1-bit indicator field is 0, it indicates that PDSCH transmitted in multiple time slots can only be received on non-SBFD symbols. When the terminal determines that the value of the 1-bit indicator field is 0, it can determine that PDSCH transmitted in multiple time slots can only be received on non-SBFD symbols.

[0120] For example, when a terminal determines that the indication field is empty, it can determine that it is able to receive PDSCH transmitted in multiple time slots on both SBFD and non-SBFD symbols.

[0121] In one embodiment, when the indication field occupies 1 bit, the indication field can indicate that PDSCH transmitted in multiple time slots can only be received on SBFD symbols, or that PDSCH transmitted in multiple time slots can be received on both SBFD and non-SBFD symbols. When the indication field is empty, it can indicate that PDSCH transmitted in multiple time slots can only be received on non-SBFD symbols.

[0122] For example, when the value of the 1 bit in the indication field is 1, it indicates that PDSCH transmitted in multiple time slots can only be received on SBFD symbols. When the terminal determines that the value of the 1 bit in the indication field is 1, it can determine that it can only receive PDSCH transmitted in multiple time slots on SBFD symbols.

[0123] For example, when the value of the 1-bit indicator field is 0, it indicates that PDSCH transmitted in multiple time slots can be received on both SBFD and non-SBFD symbols. When the terminal determines that the value of the 1-bit indicator field is 0, it can determine that it can receive PDSCH transmitted in multiple time slots on both SBFD and non-SBFD symbols.

[0124] For example, when a terminal determines that the indication field is empty, it can determine that it can only receive PDSCH transmitted in multiple time slots on non-SBFD symbols.

[0125] In one embodiment, when the indication field occupies 1 bit, the indication field can indicate that PDSCH transmitted in multiple time slots can be received on both SBFD and non-SBFD symbols, or that PDSCH transmitted in multiple time slots can only be received on non-SBFD symbols. When the indication field is empty, it can indicate that PDSCH transmitted in multiple time slots can only be received on SBFD symbols.

[0126] For example, when the value of the 1 bit in the indication field is 1, it indicates that PDSCH transmitted in multiple time slots can be received on both SBFD and non-SBFD symbols. When the terminal determines that the value of the 1 bit in the indication field is 1, it can determine that it can receive PDSCH transmitted in multiple time slots on both SBFD and non-SBFD symbols.

[0127] For example, when the value of the 1-bit indicator field is 0, it indicates that PDSCH transmitted in multiple time slots can only be received on non-SBFD symbols. When the terminal determines that the value of the 1-bit indicator field is 0, it can determine that PDSCH transmitted in multiple time slots can only be received on non-SBFD symbols.

[0128] For example, when a terminal determines that the indication field is empty, it can determine that it can only receive PDSCH transmitted in multiple time slots on the SBFD symbol.

[0129] In one embodiment, determining symbols that can be used to receive PDSCH transmitted in multiple time slots based on first information sent by the network device includes at least one of the following:

[0130] When the indication field indicates that PDSCH transmitted in multiple time slots can be received on both SBFD and non-SBFD symbols, it is determined that PDSCH transmitted in multiple time slots can be received on both SBFD and non-SBFD symbols.

[0131] When the indication field indicates that PDSCH transmitted in multiple time slots can only be received on SBFD symbols, it is determined that PDSCH transmitted in multiple time slots can only be received on SBFD symbols.

[0132] When the indication field indicates that PDSCH transmitted in multiple time slots can only be received on non-SBFD symbols, it is determined that PDSCH transmitted in multiple time slots can only be received on non-SBFD symbols.

[0133] In one embodiment, when the indication field occupies 2 bits, the indication field can indicate that PDSCH transmitted in multiple time slots can be received on both SBFD and non-SBFD symbols, or that PDSCH transmitted in multiple time slots can only be received on non-SBFD symbols, or that PDSCH transmitted in multiple time slots can only be received on SBFD symbols.

[0134] For example, when the value of the 2 bits in the indication field is 00, it indicates that PDSCH transmitted in multiple time slots can be received on both SBFD and non-SBFD symbols. When the terminal determines that the value of the 2 bits in the indication field is 00, it can determine that it can receive PDSCH transmitted in multiple time slots on both SBFD and non-SBFD symbols.

[0135] For example, when the value of the 2 bits in the indication field is 01, it indicates that PDSCH transmitted in multiple time slots can only be received on SBFD symbols. When the terminal determines that the value of the 2 bits in the indication field is 01, it can determine that it can only receive PDSCH transmitted in multiple time slots on SBFD symbols.

[0136] For example, when the value of the 2 bits in the indication field is 10, it indicates that PDSCH transmitted in multiple time slots can only be received on non-SBFD symbols. When the terminal determines that the value of the 2 bits in the indication field is 10, it can determine that PDSCH transmitted in multiple time slots can only be received on non-SBFD symbols.

[0137] It should be noted that the ability to receive PDSCH transmitted in multiple time slots for a certain type of symbol in the embodiments of this disclosure does not mean that the terminal must receive PDSCH transmitted in multiple time slots for that type of symbol. Rather, it means that the terminal can receive PDSCH transmitted in multiple time slots for that type of symbol, but cannot receive PDSCH transmitted in multiple time slots for symbols other than that type of symbol.

[0138] For example, when a terminal determines that it can receive PDSCH transmitted in multiple time slots on both SBFD and non-SBFD symbols, it means that the terminal can receive PDSCH transmitted in multiple time slots on both SBFD and non-SBFD symbols in each time slot where the PDSCH is located. It does not mean that the terminal needs to receive PDSCH transmitted in multiple time slots on both SBFD and non-SBFD symbols in every time slot where the PDSCH is located.

[0139] For example, if a terminal determines that it can only receive PDSCH transmitted in multiple time slots on an SBFD symbol, it means that the terminal can receive PDSCH transmitted in multiple time slots on an SBFD symbol within each time slot where the PDSCH resides, but cannot receive PDSCH transmitted in multiple time slots on non-SBFD symbols. It does not mean that the terminal needs to receive PDSCH transmitted in multiple time slots on an SBFD symbol within each time slot where the PDSCH resides.

[0140] For example, if a terminal determines that it can only receive PDSCH transmitted in multiple time slots on non-SBFD symbols, it means that the terminal can receive PDSCH transmitted in multiple time slots on non-SBFD symbols in each time slot where the PDSCH is located, but cannot receive PDSCH transmitted in multiple time slots on SBFD symbols. It does not mean that the terminal needs to receive PDSCH transmitted in multiple time slots on non-SBFD symbols in every time slot where the PDSCH is located.

[0141] Further determination is needed regarding which symbols in each time slot the terminal receives the PDSCH transmitted across multiple time slots. The specific determination method will be explained in subsequent embodiments.

[0142] In one embodiment, the reception determination method further includes: when it is determined that PDSCH transmitted in multiple time slots can be received on SBFD symbols and non-SBFD symbols, and the symbols occupied by PDSCH in the multiple time slots do not include SBFD symbols, receiving PDSCH on a first frequency domain resource configured in the multiple time slots.

[0143] If the terminal determines that it can receive PDSCH transmitted in multiple time slots on both SBFD and non-SBFD symbols, it can further determine whether the symbols occupied by the PDSCH in the multiple time slots include SBFD symbols.

[0144] When the symbols occupied by the PDSCH in multiple time slots do not include the SBFD symbols, the terminal will not receive the PDSCH transmitted in multiple time slots if it receives the PDSCH transmitted in multiple time slots. Therefore, the first resource FD#1 configured for the PDSCH in multiple time slots will not conflict with frequency domain resources other than downlink resources. Thus, the PDSCH can be received on FD#1 in multiple time slots. Correspondingly, the network device can send the PDSCH transmitted in multiple time slots to the terminal on FD#1 in multiple time slots.

[0145] Figure 6 This is a schematic flowchart illustrating another reception determination method according to an embodiment of the present disclosure. The reception determination method shown in this embodiment can be executed by a terminal. Figure 6 As shown, the receiving determination method also includes:

[0146] In step S601, when it is determined that PDSCH transmitted in multiple time slots can be received on both SBFD and non-SBFD symbols, and the symbols occupied by PDSCH in the first time slot of the multiple time slots include at least one SBFD symbol, and the first frequency domain resource configured for PDSCH in the first time slot includes frequency domain resources located outside the downlink resources corresponding to the SBFD symbol, PDSCH is not received in the first time slot.

[0147] It should be noted that, Figure 6 The illustrated embodiments can be implemented independently or in combination with at least one other embodiment of this disclosure, depending on the specific requirements; this disclosure is not limiting. Furthermore, the first frequency domain resource configured in each time slot for PDSCH transmitted in multiple time slots can be the same. The first time slot can refer to any one of the multiple time slots.

[0148] In one embodiment, the reception determination method further includes: receiving the PDSCH in the first time slot when it is determined that the PDSCH transmitted in multiple time slots can be received on both SBFD symbols and non-SBFD symbols, and the first frequency domain resource configured for the PDSCH in the first time slot of the multiple time slots is within the downlink resource corresponding to the SBFD symbol.

[0149] In one embodiment, if the terminal determines that it can receive PDSCH transmitted in multiple time slots on both SBFD symbols and non-SBFD symbols, it can further determine whether the first frequency domain resource FD#1 configured for the PDSCH in the first time slot of the multiple time slots contains frequency domain resources other than the downlink resources corresponding to the SBFD symbols.

[0150] When FD#1 contains frequency domain resources outside the downlink resources corresponding to the SBFD symbol (i.e., FD#1 is not located within the downlink resources corresponding to the SBFD symbol), if the terminal receives PDSCH transmitted in multiple time slots via the SBFD symbol in the first time slot, FD#1 will conflict with the frequency domain resources outside the downlink resources. Therefore, it is not necessary to receive PDSCH transmitted in multiple time slots in the first time slot. Correspondingly, the network device may not send PDSCH transmitted in multiple time slots to the terminal in the first time slot.

[0151] When FD#1 does not contain frequency domain resources outside the downlink resources corresponding to the SBFD symbol (i.e., FD#1 is within the downlink resources corresponding to the SBFD symbol), the terminal will not conflict with frequency domain resources outside the downlink resources when receiving PDSCH transmitted in multiple time slots via the SBFD symbol in the first time slot. Therefore, PDSCH can be received in the first time slot. Correspondingly, the network device can send PDSCH transmitted in multiple time slots to the terminal in the first time slot.

[0152] In one embodiment, the reception determination method further includes: if the symbols occupied by the PDSCH in a first time slot of a plurality of time slots include uplink symbols, then the PDSCH is not received in the first time slot. This embodiment can be combined with any other embodiment in this disclosure.

[0153] Regardless of whether the terminal determines it can receive PDSCH transmitted in multiple time slots on both SBFD and non-SBFD symbols, or only on SBFD symbols, or only on non-SBFD symbols, it can determine whether the symbols occupied by the PDSCH in the first time slot of the multiple time slots used for receiving the PDSCH include uplink symbols. If it is determined that the symbols occupied by the PDSCH in the first time slot include uplink symbols, then FD#1 will conflict with frequency domain resources other than downlink resources, and therefore the PDSCH can be excluded from reception in the first time slot. Correspondingly, the network device can choose not to send the PDSCH transmitted in multiple time slots to the terminal in the first time slot.

[0154] Figure 7 This is a schematic flowchart illustrating another reception determination method according to an embodiment of the present disclosure. The reception determination method shown in this embodiment can be executed by a terminal. Figure 7 As shown, the receiving determination method also includes:

[0155] In step S701, when it is determined that PDSCH transmitted in multiple time slots can be received on both SBFD symbols and non-SBFD symbols, the symbols occupied by PDSCH in the multiple time slots include at least one SBFD symbol, and there is an overlapping second frequency domain resource between the first frequency domain resource configured for PDSCH and the downlink resource corresponding to the SBFD symbol in the multiple time slots, PDSCH is received on the second frequency domain resource in the multiple time slots.

[0156] It should be noted that, Figure 7 The illustrated embodiments can be implemented independently or in combination with at least one other embodiment of this disclosure, depending on the specific requirements. This disclosure does not limit the scope of the embodiments. This embodiment is applicable to situations where the first information is based on a display instruction.

[0157] In one embodiment, if the terminal determines that it can receive PDSCH transmitted in multiple time slots on both SBFD symbols and non-SBFD symbols, it can further determine whether there is an overlapping second frequency domain resource FD#2 between the first frequency domain resource FD#1 configured for PDSCH in the multiple time slots and the downlink resource corresponding to the SBFD symbol.

[0158] When there is an overlapping second frequency domain resource FD#2 between the downlink resources corresponding to FD#1 and SBFD symbols, the terminal can receive PDSCH transmitted in multiple time slots in FD#2 during the multiple time slots used to receive PDSCH.

[0159] Since FD#2 is located within the downlink resources corresponding to the SBFD symbol, receiving PDSCH transmitted in multiple time slots at FD#2 ensures that the frequency domain resources for receiving PDSCH on the SBFD symbol in each time slot do not conflict with frequency domain resources outside the downlink resources. Correspondingly, network devices can send PDSCH transmitted in multiple time slots to the terminal only at FD#2 in multiple time slots.

[0160] Figure 8 This is a schematic flowchart illustrating another reception determination method according to an embodiment of the present disclosure. The reception determination method shown in this embodiment can be executed by a terminal. Figure 8 As shown, the receiving determination method also includes:

[0161] In step S801, when it is determined that PDSCH transmitted in multiple time slots can be received on SBFD symbols and non-SBFD symbols, the symbols occupied by PDSCH in the multiple time slots include at least one SBFD symbol, and there is an overlapping second frequency domain resource between the first frequency domain resource configured for PDSCH and the downlink resource corresponding to the SBFD symbol in the multiple time slots, PDSCH is received on the second frequency domain resource on the SBFD symbol in the first time slot of the multiple time slots, and PDSCH is received on the first frequency domain resource on the non-SBFD symbol in the first time slot.

[0162] It should be noted that, Figure 8 The embodiments shown can be implemented independently or in combination with at least one other embodiment of this disclosure. The specific choice can be made as needed, and this disclosure does not limit the scope of the embodiments.

[0163] In one embodiment, if the terminal determines that it can receive PDSCH transmitted in multiple time slots on both SBFD symbols and non-SBFD symbols, it can further determine whether there is an overlapping second frequency domain resource FD#2 between the first frequency domain resource FD#1 configured for PDSCH in the first time slot of the multiple time slots and the downlink resource corresponding to the SBFD symbol.

[0164] When there is an overlapping second frequency domain resource FD#2 between the downlink resources corresponding to FD#1 and SBFD symbols, the terminal can receive PDSCH transmitted in multiple time slots on FD#2 on the SBFD symbol in the first time slot, while it can receive PDSCH transmitted in multiple time slots on FD#1 on the non-SBFD symbol in the first time slot.

[0165] Since FD#2 is located within the downlink resources corresponding to the SBFD symbol, receiving PDSCH transmitted in multiple time slots on FD#2 of the SBFD symbol ensures that the frequency domain resources for receiving PDSCH on the SBFD symbol in each time slot do not conflict with frequency domain resources outside the downlink resources. On non-SBFD symbols, there are no frequency domain resources outside the downlink resources; therefore, receiving PDSCH transmitted in multiple time slots on FD#1 of the non-SBFD symbol does not conflict with frequency domain resources outside the downlink resources and helps ensure full utilization of frequency domain resources. Correspondingly, on the SBFD symbol in the first time slot, the network device can send PDSCH transmitted in multiple time slots to the terminal only on FD#2; on the non-SBFD symbols in the first time slot, it can send PDSCH transmitted in multiple time slots to the terminal on FD#1.

[0166] Figure 9 This is a schematic flowchart illustrating another reception determination method according to an embodiment of the present disclosure. The reception determination method shown in this embodiment can be executed by a terminal. Figure 9 As shown, the receiving determination method also includes:

[0167] In step S901, when it is determined that PDSCH transmitted in multiple time slots can be received on both SBFD and non-SBFD symbols, and the symbols occupied by PDSCH in the multiple time slots include at least one SBFD symbol, and the symbols occupied by PDSCH in the first time slot of the multiple time slots do not include SBFD symbols, PDSCH is received on the first frequency domain resource configured for PDSCH in the first time slot, and / or, when the symbols occupied by PDSCH in the first time slot of the multiple time slots include SBFD symbols, PDSCH is received on the second frequency domain resource overlapping between the first frequency domain resource configured for PDSCH and the downlink resource corresponding to the SBFD symbol in the first time slot.

[0168] It should be noted that, Figure 9 The embodiments shown can be implemented independently or in combination with at least one other embodiment of this disclosure. The specific choice can be made as needed, and this disclosure does not limit the scope of the embodiments.

[0169] In one embodiment, if a terminal determines that it is able to receive PDSCH transmitted in multiple time slots on both SBFD and non-SBFD symbols, and the symbols occupied by the PDSCH in the multiple time slots include at least one SBFD symbol, it may further determine whether the symbols occupied by the PDSCH in the first time slot of the multiple time slots include SBFD symbols.

[0170] For example, when it is determined that the symbols occupied by PDSCH in the first time slot do not include SBFD symbols, the first frequency domain resources configured for PDSCH in the first time slot will not conflict with the frequency domain resources other than the downlink resources. Therefore, the terminal can receive PDSCH on the first frequency domain resources configured for PDSCH in the first time slot.

[0171] For example, when it is determined that the symbols occupied by PDSCH in the first time slot include SBFD symbols, the terminal can further determine the second frequency domain resources that overlap between the first frequency domain resources configured for PDSCH and the downlink resources corresponding to the SBFD symbols in the first time slot. Since the second frequency domain resources are within the downlink resources corresponding to the SBFD symbols, they will not conflict with the frequency domain resources outside the downlink resources. Therefore, the terminal can receive PDSCH on the second frequency domain resources in the first time slot.

[0172] Figure 10 This is a schematic flowchart illustrating another reception determination method according to an embodiment of the present disclosure. The reception determination method shown in this embodiment can be executed by a terminal. Figure 10 As shown, the receiving determination method also includes:

[0173] In step S1001, when it is determined that PDSCH transmitted in multiple time slots can be received on SBFD symbols and non-SBFD symbols, and a third frequency domain resource for receiving PDSCH on SBFD symbols and a fourth frequency domain resource for receiving PDSCH on non-SBFD symbols are configured, PDSCH is received on the third frequency domain resource on SBFD symbols and PDSCH is received on the fourth frequency domain resource on non-SBFD symbols.

[0174] It should be noted that, Figure 10 The embodiments shown can be implemented independently or in combination with at least one other embodiment of this disclosure. The specific choice can be made as needed, and this disclosure does not limit the scope of the embodiments.

[0175] In one embodiment, when a terminal determines that it can receive PDSCH transmitted in multiple time slots on SBFD symbols and non-SBFD symbols, and the symbols occupied by the PDSCH in the multiple time slots include at least one SBFD symbol, it can further determine whether the network device has configured a third frequency domain resource for receiving PDSCH on SBFD symbols and a fourth frequency domain resource for receiving PDSCH on non-SBFD symbols, wherein the third frequency domain resource does not include frequency domain resources other than the downlink resources corresponding to the SBFD symbols.

[0176] When it is determined that the network device is configured with third frequency domain resources for receiving PDSCH on SBFD symbols and fourth frequency domain resources for receiving PDSCH on non-SBFD symbols, since the third frequency domain resources do not include frequency domain resources other than the downlink resources corresponding to the SBFD symbols, there will be no conflict between the third frequency domain resources and the frequency domain resources other than the downlink resources. Therefore, on the SBFD symbols occupied by PDSCH in multiple time slots used for PDSCH transmission, PDSCH transmitted in multiple time slots can be received on the third frequency domain resources. Correspondingly, the network device can send PDSCH transmitted in multiple time slots to the terminal on the SBFD symbols occupied by PDSCH in multiple time slots used for PDSCH transmission on the third frequency domain resources.

[0177] Since there are no frequency domain resources other than downlink resources on non-SBFD symbols, the fourth frequency domain resources will not conflict with frequency domain resources other than downlink resources. Therefore, PDSCH can be received on the fourth frequency domain resources on the non-SBFD symbols occupied by PDSCH in multiple time slots used for PDSCH transmission. Correspondingly, network devices can send PDSCH transmitted in multiple time slots to the terminal on the fourth frequency domain resources on the non-SBFD symbols occupied by PDSCH in multiple time slots used for PDSCH transmission.

[0178] Figure 11 This is a schematic flowchart illustrating another reception determination method according to an embodiment of the present disclosure. The reception determination method shown in this embodiment can be executed by a terminal. Figure 11 As shown, the receiving determination method also includes:

[0179] In step S1101, when it is determined that PDSCH transmitted in multiple time slots can be received on both SBFD and non-SBFD symbols, and the symbol where the PDSCH is located in the first time slot of the multiple time slots includes a non-SBFD symbol, if the downlink resource corresponding to the non-SBFD symbol is greater than or equal to the first frequency domain resource configured for the PDSCH, a fifth frequency domain resource is determined in the downlink resource, and the PDSCH is received on the fifth frequency domain resource in the first time slot, wherein the bandwidth of the fifth frequency domain resource is equal to that of the first frequency domain resource; and / or if the downlink resource corresponding to the non-SBFD symbol is less than the first frequency domain resource configured for the PDSCH, the PDSCH is not received in the first time slot.

[0180] It should be noted that, Figure 11 The embodiments shown can be implemented independently or in combination with at least one other embodiment of this disclosure. The specific choice can be made as needed, and this disclosure does not limit the scope of the embodiments.

[0181] In one embodiment, when a terminal determines that it can receive PDSCH transmitted in multiple time slots on both SBFD and non-SBFD symbols, and the symbol where the PDSCH is located in the first time slot of the multiple time slots includes a non-SBFD symbol, it can further determine the relationship between the downlink resources corresponding to the non-SBFD symbol and the first frequency domain resources configured for the PDSCH.

[0182] When the downlink resource corresponding to a non-SBFD symbol is greater than or equal to the first frequency domain resource configured for PDSCH, a frequency domain resource with bandwidth equal to that of the first frequency domain resource can be determined from the downlink resources corresponding to the non-SBFD symbol, for example, called the fifth frequency domain resource. Then, PDSCH can be received on the fifth frequency domain resource in the first time slot. Since the bandwidth of the fifth frequency domain resource is equal to that of the first frequency domain resource, it helps ensure successful PDSCH reception. Correspondingly, the network device can send PDSCH transmitted in multiple time slots to the terminal on the fifth frequency domain resource in the first time slot.

[0183] In one embodiment, the bandwidth of the first frequency domain resource can be determined first, wherein the bandwidth can be characterized by the number of resource blocks (RBs), for example, k1 RBs.

[0184] For example, starting from the initial RB of the active bandwidth part (BWP) corresponding to the first time slot, k1 consecutive RBs can be determined within the active BWP. If there are only k1-n RBs from the initial RB of the active BWP to the first boundary of the resource outside the downlink resource (the boundary relatively close to the initial RB), then n more RBs can be determined within the downlink resource starting from the second boundary of the resource outside the downlink resource (the boundary relatively far from the initial RB). The determined k1-n RBs and n RBs are then used as the fifth frequency domain range.

[0185] For example, the endpoint can be the ending RB of the active BWP corresponding to the first time slot, and k1 consecutive RBs can be determined in the active BWP. If there are only k1-n RBs from the ending RB of the active BWP to the second boundary of the resource outside the downlink resource (the boundary relatively close to the ending RB), n more RBs can be determined in the downlink resource starting from the first boundary of the resource outside the downlink resource (the boundary relatively far from the ending RB), and then the determined k1-n RBs and n RBs can be used as the fifth frequency domain range.

[0186] For example, in the activated BWP, a frequency domain range with a duration of k2 consecutive RBs can be determined as the sixth frequency domain resource, and the k1 RBs overlapping the sixth frequency domain resource and the downlink resources corresponding to non-SBFD symbols can be determined as the fifth frequency domain range.

[0187] When the downlink resource corresponding to a non-SBFD symbol is less than the first frequency domain resource configured for the PDSCH, then a frequency domain resource with bandwidth equal to the first frequency domain resource cannot be determined within the downlink resource corresponding to the non-SBFD symbol, and the terminal does not receive the PDSCH in the first time slot. Correspondingly, the network device may not send the PDSCH transmitted in multiple time slots to the terminal in the first time slot.

[0188] Figure 12 This is a schematic flowchart illustrating another reception determination method according to an embodiment of the present disclosure. The reception determination method shown in this embodiment can be executed by a terminal. Figure 12 As shown, the receiving determination method also includes:

[0189] In step S1201, when it is determined that PDSCH transmitted in multiple time slots can only be received on SBFD symbols, and there is an overlapping second frequency domain resource between the first frequency domain resource configured for PDSCH and the downlink resource corresponding to the SBFD symbol in the first time slot of the multiple time slots, if the symbols occupied by PDSCH in the first time slot include non-SBFD symbols, PDSCH is not received in the first time slot; and / or, if the symbols occupied by PDSCH in the first time slot include SBFD symbols but do not include uplink symbols, PDSCH is received on the second frequency domain resource in the first time slot; and / or, if the symbols occupied by PDSCH in the first time slot only include SBFD symbols, PDSCH is received on the second frequency domain resource in the first time slot.

[0190] It should be noted that, Figure 12 The embodiments shown can be implemented independently or in combination with at least one other embodiment of this disclosure. The specific choice can be made as needed, and this disclosure does not limit the scope of the embodiments.

[0191] In one embodiment, when a terminal determines that it can only receive PDSCH transmitted in multiple time slots on SBFD symbols, and there is an overlapping second frequency domain resource between the first frequency domain resource configured for PDSCH and the downlink resource corresponding to the SBFD symbol in the first time slot of the multiple time slots, it can further determine whether the symbols occupied by PDSCH in the first time slot include non-SBFD symbols.

[0192] For example, if the symbols occupied by the PDSCH in the first time slot include non-SBFD symbols, receiving the PDSCH in the first time slot would result in the PDSCH occupying non-SBFD symbols, which violates the limitation that PDSCH transmitted in multiple time slots can only be received on SBFD symbols. Therefore, the terminal may choose not to receive the PDSCH transmitted in multiple time slots in the first time slot. Correspondingly, the network device may choose not to send the PDSCH transmitted in multiple time slots to the terminal in the first time slot.

[0193] For example, if the symbols occupied by the PDSCH in the first time slot include SBFD symbols but not uplink symbols, and the PDSCH is received in the first time slot, the restriction that PDSCH transmitted in multiple time slots can only be received on SBFD symbols meets the requirement. Therefore, the terminal can receive PDSCH transmitted in multiple time slots on the second frequency domain resources in the first time slot. Correspondingly, the network device can send PDSCH transmitted in multiple time slots to the terminal on the second frequency domain resources in the first time slot.

[0194] For example, if the symbols occupied by the PDSCH in the first time slot only include SBFD symbols, and the PDSCH is received in the first time slot, the restriction that PDSCH transmitted in multiple time slots can only be received on SBFD symbols meets the requirement. Therefore, the terminal can receive PDSCH transmitted in multiple time slots on the second frequency domain resources in the first time slot. Correspondingly, the network device can send PDSCH transmitted in multiple time slots to the terminal on the second frequency domain resources in the first time slot.

[0195] Figure 13 This is a schematic flowchart illustrating another reception determination method according to an embodiment of the present disclosure. The reception determination method shown in this embodiment can be executed by a terminal. Figure 13 As shown, the receiving determination method also includes:

[0196] In step S1301, when it is determined that PDSCH transmitted in multiple time slots can only be received on non-SBFD symbols, if the symbols occupied by PDSCH in the first time slot of the multiple time slots include SBFD symbols, PDSCH is not received in the first time slot; and / or, if the symbols occupied by PDSCH in the first time slot include downlink symbols and / or flexible symbols, but do not include uplink symbols, PDSCH is received in the first time slot; and / or, if the symbols occupied by PDSCH in the first time slot only include downlink symbols and / or flexible symbols, PDSCH is received in the first time slot.

[0197] It should be noted that, Figure 13 The embodiments shown can be implemented independently or in combination with at least one other embodiment of this disclosure. The specific choice can be made as needed, and this disclosure does not limit the scope of the embodiments.

[0198] In one embodiment, after determining that the terminal can only receive PDSCH transmitted in multiple time slots on non-SBFD symbols, it can further determine the symbol occupied by the PDSCH in the first time slot.

[0199] For example, if the symbols occupied by the PDSCH in the first time slot include SBFD symbols, receiving the PDSCH in the first time slot would result in the PDSCH occupying symbols including SBFD symbols, which violates the limitation that PDSCH transmitted in multiple time slots can only be received on non-SBFD symbols. Therefore, the terminal may choose not to receive the PDSCH transmitted in multiple time slots in the first time slot. Correspondingly, the network device may choose not to send the PDSCH transmitted in multiple time slots to the terminal in the first time slot.

[0200] For example, if the symbols occupied by the PDSCH in the first time slot include downlink symbols and / or flexible symbols, but not uplink symbols, and if the PDSCH is received in the first time slot, the symbols occupied by the PDSCH include downlink symbols and / or flexible symbols, but not uplink symbols. Non-SBFD symbols, on the other hand, include downlink symbols, flexible symbols, and uplink symbols. This meets the limitation that PDSCH transmitted in multiple time slots can only be received on non-SBFD symbols. Therefore, the terminal can receive PDSCH transmitted in multiple time slots in the first time slot. Correspondingly, the network device can send PDSCH transmitted in multiple time slots to the terminal in the first time slot.

[0201] For example, if the symbols occupied by the PDSCH in the first time slot only include downlink symbols and / or flexible symbols, and the PDSCH is received in the first time slot, the symbols occupied by the PDSCH also only include downlink symbols and / or flexible symbols. This conforms to the limitation that PDSCH transmitted in multiple time slots can only be received on non-SBFD symbols. Therefore, the terminal can receive PDSCH transmitted in multiple time slots in the first time slot. Correspondingly, the network device can send PDSCH transmitted in multiple time slots to the terminal in the first time slot.

[0202] Figure 14 This is a schematic flowchart illustrating a receiving instruction method according to an embodiment of the present disclosure. The receiving instruction method shown in this embodiment can be executed by a network device, which can communicate with a terminal. The network device includes, but is not limited to, base stations in communication systems such as 4G base stations, 5G base stations, and 6G base stations. The terminal includes, but is not limited to, communication devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices.

[0203] like Figure 14 As shown, the method for receiving an instruction may include the following steps:

[0204] In step S1401, first information is sent to the terminal, wherein the first information is used to indicate that the terminal is capable of receiving symbols of PDSCH transmitted in multiple time slots, and the symbols include at least one of the following: SBFD symbols and non-SBFD symbols.

[0205] In one embodiment, the network device may send first information to the terminal to indicate that the terminal is capable of receiving symbols of PDSCH transmitted in multiple time slots, wherein the symbols include at least one of the following: SBFD symbols and non-SBFD symbols. That is, the first information may indicate that the terminal can receive PDSCH transmitted in multiple time slots using SBFD symbols and non-SBFD symbols, or can only receive PDSCH transmitted in multiple time slots using SBFD symbols, or can only receive PDSCH transmitted in multiple time slots using non-SBFD symbols.

[0206] For example, a network device may determine that it can only send PDSCH transmitted in multiple time slots to a terminal on SBFD symbols, and then instruct the terminal to receive PDSCH transmitted in multiple time slots on SBFD symbols through a first information; or, it may determine that it can only send PDSCH transmitted in multiple time slots to a terminal on non-SBFD symbols, and then instruct the terminal to receive PDSCH transmitted in multiple time slots on non-SBFD symbols through a first information; or, it may determine that it can send PDSCH transmitted in multiple time slots to a terminal on both SBFD symbols and non-SBFD symbols, and then instruct the terminal to receive PDSCH transmitted in multiple time slots on both SBFD symbols and non-SBFD symbols through a first information.

[0207] Therefore, it can be ensured that the symbols that the terminal determines can be used to receive PDSCH transmitted in multiple time slots are the same as the symbols that the network device determines can be used to send PDSCH to the terminal in multiple time slots. This achieves consistency in understanding between the terminal and the network device, which helps to ensure the communication quality between the network device and the terminal.

[0208] It should be noted that the embodiments disclosed herein are mainly exemplified when the SBFD symbol is a symbol configured with an uplink subband. However, the technical solutions disclosed herein can also be applied to the case where the SBFD symbol is a symbol configured with a downlink subband.

[0209] In one embodiment, the first information includes at least one of the following: frequency domain resource information; an indication field.

[0210] In one embodiment, when it is determined that the symbols that can be used to transmit PDSCH to the terminal in multiple time slots include SBFD symbols and non-SBFD symbols, the frequency domain resource information configures the frequency domain resources of the PDSCH to be within the downlink resources corresponding to the SBFD symbols; and / or, when it is determined that the symbols that can be used to transmit PDSCH to the terminal in multiple time slots include SBFD symbols or non-SBFD symbols, the frequency domain resource information configures the frequency domain resources of the PDSCH to include frequency domain resources located outside the downlink resources corresponding to the SBFD symbols.

[0211] like Figure 4AAs shown, the network device can determine that it can send PDSCH transmitted in multiple time slots to the terminal on both SBFD symbols and non-SBFD symbols. The frequency domain resource information sent by the network device to the terminal can be configured so that the frequency domain resource of the PDSCH transmitted in multiple time slots is FD#1, and FD#1 is within the downlink resource corresponding to the SBFD symbol. When the terminal determines that FD#1 is within the downlink resource corresponding to the SBFD symbol, it can further determine that it can receive PDSCH transmitted in multiple time slots on both SBFD symbols and non-SBFD symbols. For example, it can determine that it can receive PDSCH transmitted in multiple time slots on symbols #3 to #8. Correspondingly, the network device sends PDSCH transmitted in multiple time slots to the terminal on symbols #3 to #8.

[0212] like Figure 4B As shown, the network device can determine that it can send PDSCH transmitted in multiple time slots to the terminal on non-SBFD symbols. Therefore, the frequency domain resource information sent by the network device to the terminal can be configured so that the frequency domain resource of the PDSCH transmitted in multiple time slots is FD#1, and FD#1 includes frequency domain resources located outside the downlink resources corresponding to the SBFD symbol. When the terminal determines that FD#1 includes frequency domain resources located outside the downlink resources corresponding to the SBFD symbol (e.g., ...), ... Figure 4B If there is a resource conflict between FD#1 and frequency domain resources other than downlink resources, it can be further determined that PDSCH transmitted in multiple time slots can only be received on SBFD symbols or non-SBFD symbols. For example, it can be determined that PDSCH transmitted in multiple time slots can only be received on non-SBFD symbols (symbols #3 to #5). Correspondingly, the network device sends PDSCH transmitted in multiple time slots to the terminal on symbols #3 to #5.

[0213] It should be noted that when a network device determines that it can only send PDSCH transmitted in multiple time slots to the terminal on SBFD symbols, the frequency domain resource information can also be configured so that FD#1 includes frequency domain resources other than the downlink resources corresponding to the SBFD symbols. However, in this case, the first PDSCH in the PDSCH transmitted in multiple time slots must include the SBFD symbols, or all the first PDSCH symbols in the PDSCH transmitted in multiple time slots must be SBFD symbols, so that the terminal can determine that it can only receive PDSCH transmitted in multiple time slots on SBFD symbols.

[0214] In one embodiment, determining that PDSCH transmitted in multiple time slots can only be sent to the terminal on either SBFD symbols or non-SBFD symbols includes at least one of the following:

[0215] The symbol containing the first PDSCH in a PDSCH transmitted in multiple time slots includes the SBFD symbol, which determines that the PDSCH transmitted in multiple time slots can only be sent to the terminal on the SBFD symbol;

[0216] In a PDSCH transmitted across multiple time slots, the first PDSCH symbol is entirely composed of non-SBFD symbols, indicating that the PDSCH transmitted across multiple time slots can only be sent to the terminal on non-SBFD symbols.

[0217] For example, a network device can determine the time slot of the first PDSCH in multiple time slots, and determine the symbol of the first PDSCH in that time slot. If the symbol of the first PDSCH in that time slot includes an SBFD symbol, the network device can determine that it can only send the PDSCH transmitted in multiple time slots to the terminal on SBFD symbols; if all the symbols of the first PDSCH in that time slot are non-SBFD symbols, the network device can determine that it can only send the PDSCH transmitted in multiple time slots to the terminal on non-SBFD symbols.

[0218] In one embodiment, determining that PDSCH transmitted in multiple time slots can only be sent to the terminal on either SBFD symbols or non-SBFD symbols includes at least one of the following:

[0219] The first PDSCH in a PDSCH transmitted in multiple time slots is a symbol that is an SBFD symbol, which means that the PDSCH transmitted in multiple time slots can only be sent to the terminal on the SBFD symbol.

[0220] The symbol containing the first PDSCH in a PDSCH transmitted in multiple time slots includes a non-SBFD symbol, which determines that the PDSCH transmitted in multiple time slots can only be sent to the terminal on a non-SBFD symbol.

[0221] For example, a network device can determine the time slot of the first PDSCH in multiple time slots, and determine the symbol of the first PDSCH in that time slot. If all the symbols of the first PDSCH in that time slot are SBFD symbols, the network device can determine that it can only send the PDSCH transmitted in multiple time slots to the terminal on SBFD symbols; if the symbols of the first PDSCH in that time slot include non-SBFD symbols, the network device can determine that it can only send the PDSCH transmitted in multiple time slots to the terminal on non-SBFD symbols.

[0222] In one embodiment, when it is determined that the symbols that can be used to send PDSCH to the terminal for transmission in multiple time slots include SBFD symbols and non-SBFD symbols, and the frequency domain resource information configures the frequency domain resources of the PDSCH to include frequency domain resources on SBFD symbols for receiving PDSCH and frequency domain resources on non-SBFD symbols for receiving PDSCH, it is determined that PDSCH can be sent in multiple time slots on both SBFD symbols and non-SBFD symbols.

[0223] In one embodiment, when the network device determines that the symbols that can be used to send PDSCH transmitted in multiple time slots to the terminal include SBFD symbols and non-SBFD symbols, the first information sent to the terminal may include frequency domain resource information. The frequency domain resource information may be configured with frequency domain resources for receiving PDSCH on SBFD symbols and frequency domain resources for receiving PDSCH on non-SBFD symbols. The frequency domain resources for receiving PDSCH on SBFD symbols do not include frequency domain resources located outside the downlink resources corresponding to the SBFD symbols.

[0224] In this scenario, network devices can send PDSCH transmitted in multiple time slots to the terminal on both SBFD and non-SBFD symbols. The terminal can determine, based on frequency domain resource information, whether it can receive PDSCH transmitted in multiple time slots on both SBFD and non-SBFD symbols.

[0225] For example, in a non-SBFD symbol, PDSCH can be sent to the terminal on the frequency domain resources used for receiving PDSCH on the non-SBFD symbol, while in an SBFD symbol, PDSCH can be sent to the terminal on the frequency domain resources used for receiving PDSCH on the SBFD symbol.

[0226] In one embodiment, the indicator field occupies 1 bit or 2 bits. It should be noted that the number of bits occupied by the indicator field is not limited to 1 or 2; it can also be other numbers. The following embodiments mainly illustrate the technical solutions of this disclosure for the cases where the indicator field occupies 1 bit and 2 bits.

[0227] In one embodiment, when it is determined that the symbols that can be used to send PDSCH transmitted in multiple time slots to the terminal include SBFD symbols and non-SBFD symbols, the indication field indicates that the terminal can receive PDSCH transmitted in multiple time slots on both SBFD and non-SBFD symbols; and / or, when it is determined that the symbols that can be used to send PDSCH transmitted in multiple time slots to the terminal include either SBFD symbols or non-SBFD symbols, the indication field indicates that the terminal can only receive PDSCH transmitted in multiple time slots on either SBFD symbols or non-SBFD symbols.

[0228] In one embodiment, when the indication field occupies 1 bit, the indication field can indicate to the terminal that it is possible to receive PDSCH transmitted in multiple time slots on both SBFD and non-SBFD symbols, or it can indicate to the terminal that it is possible to receive PDSCH transmitted in multiple time slots on either SBFD or non-SBFD symbols.

[0229] For example, when a network device determines that the symbols that can be used to send PDSCH transmitted in multiple time slots to a terminal include SBFD symbols and non-SBFD symbols, the 1-bit value of the indication field sent to the terminal is 1, indicating that the terminal can receive PDSCH transmitted in multiple time slots in both SBFD and non-SBFD symbols.

[0230] For example, when a network device determines that the symbols that can be used to send PDSCH transmitted in multiple time slots to a terminal include SBFD symbols or non-SBFD symbols, and the value of 1 bit in the indication field sent to the terminal is 0, the terminal is instructed to receive PDSCH transmitted in multiple time slots only in SBFD symbols or non-SBFD symbols.

[0231] In one embodiment, determining that PDSCH transmitted in multiple time slots can only be sent to the terminal on either SBFD symbols or non-SBFD symbols includes at least one of the following:

[0232] The symbol containing the first PDSCH in a PDSCH transmitted in multiple time slots includes the SBFD symbol, which determines that the PDSCH transmitted in multiple time slots can only be sent to the terminal on the SBFD symbol;

[0233] In a PDSCH transmitted across multiple time slots, the first PDSCH symbol is entirely composed of non-SBFD symbols, indicating that the PDSCH transmitted across multiple time slots can only be sent to the terminal on non-SBFD symbols.

[0234] For example, a network device can determine the time slot of the first PDSCH in multiple time slots, and determine the symbol of the first PDSCH in that time slot. If the symbol of the first PDSCH in that time slot includes an SBFD symbol, the network device can determine that it can only send the PDSCH transmitted in multiple time slots to the terminal on SBFD symbols; if all the symbols of the first PDSCH in that time slot are non-SBFD symbols, the network device can determine that it can only send the PDSCH transmitted in multiple time slots to the terminal on non-SBFD symbols.

[0235] In one embodiment, determining that PDSCH transmitted in multiple time slots can only be sent to the terminal on either SBFD symbols or non-SBFD symbols includes at least one of the following:

[0236] The first PDSCH in a PDSCH transmitted in multiple time slots is a symbol that is an SBFD symbol, which means that the PDSCH transmitted in multiple time slots can only be sent to the terminal on the SBFD symbol.

[0237] The symbol containing the first PDSCH in a PDSCH transmitted in multiple time slots includes a non-SBFD symbol, which determines that the PDSCH transmitted in multiple time slots can only be sent to the terminal on a non-SBFD symbol.

[0238] For example, a network device can determine the time slot of the first PDSCH in multiple time slots, and determine the symbol of the first PDSCH in that time slot. If all the symbols of the first PDSCH in that time slot are SBFD symbols, the network device can determine that it can only send the PDSCH transmitted in multiple time slots to the terminal on SBFD symbols; if the symbols of the first PDSCH in that time slot include non-SBFD symbols, the network device can determine that it can only send the PDSCH transmitted in multiple time slots to the terminal on non-SBFD symbols.

[0239] In one embodiment, determining that PDSCH transmitted in multiple time slots can only be sent to the terminal on either SBFD symbols or non-SBFD symbols includes at least one of the following:

[0240] The first PDSCH in a PDSCH transmitted in multiple time slots is a symbol that is an SBFD symbol, which means that the PDSCH transmitted in multiple time slots can only be sent to the terminal on the SBFD symbol.

[0241] In a PDSCH transmitted across multiple time slots, the first PDSCH symbol is entirely composed of non-SBFD symbols, indicating that the PDSCH transmitted across multiple time slots can only be sent to the terminal on non-SBFD symbols.

[0242] For example, a network device can determine the time slot of the first PDSCH in a PDSCH transmitted across multiple time slots, and determine the symbol in that time slot where the first PDSCH is located. If all the symbols in that time slot where the first PDSCH is located are SBFD symbols, the network device can determine that it can only send the PDSCH transmitted across multiple time slots to the terminal on SBFD symbols; if all the symbols in that time slot where the first PDSCH is located are non-SBFD symbols, the network device can determine that it can only send the PDSCH transmitted across multiple time slots to the terminal on non-SBFD symbols.

[0243] In one embodiment, determining symbols that can be used to transmit PDSCH in multiple time slots includes at least one of the following:

[0244] When it is determined that the symbols that can be used to send PDSCH transmitted in multiple time slots to the terminal include only SBFD symbols, the terminal is instructed to receive PDSCH transmitted in multiple time slots only on SBFD symbols, wherein the indication field takes the first value, the second value, or the indication field is empty;

[0245] When it is determined that the symbols that can be used to send PDSCH transmitted in multiple time slots to the terminal include only non-SBFD symbols, the terminal is instructed to receive PDSCH transmitted in multiple time slots only on non-SBFD symbols, wherein the indication field takes the first value, the second value, or the indication field is empty;

[0246] When it is determined that a PDSCH transmitted in multiple time slots can be sent on both SBFD and non-SBFD symbols, the terminal is instructed to receive a PDSCH transmitted in multiple time slots on both SBFD and non-SBFD symbols, wherein the instruction field takes a first value, a second value, or is empty.

[0247] It is understood that the content indicated by the first information differs depending on whether the indicator field takes a first value, a second value, or is empty. The following examples illustrate the content indicated by the first information when the indicator field takes a first value, a second value, or is empty. However, the correspondence between the content indicated by the first information and the indicator field taking a first value, a second value, or being empty is not limited to the following examples.

[0248] In one embodiment, when the indication field occupies 1 bit, the indication field can indicate to the terminal that PDSCH transmitted in multiple time slots can only be received on SBFD symbols, or that PDSCH transmitted in multiple time slots can only be received on non-SBFD symbols. When the indication field is empty, it can indicate to the terminal that PDSCH transmitted in multiple time slots can be received on both SBFD symbols and non-SBFD symbols.

[0249] For example, if a network device determines that it can only send PDSCH transmitted in multiple time slots to the terminal on the SBFD symbol, the 1-bit value of the indication field sent to the terminal is 1, indicating to the terminal that it can only receive PDSCH transmitted in multiple time slots on the SBFD symbol.

[0250] For example, if a network device determines that it can only send PDSCH transmitted in multiple time slots to a terminal on a non-SBFD symbol, the 1-bit value of the indication field sent to the terminal is 0, indicating to the terminal that it can only receive PDSCH transmitted in multiple time slots on a non-SBFD symbol.

[0251] For example, if a network device determines that it can send PDSCH transmitted in multiple time slots to a terminal on both SBFD and non-SBFD symbols, the network device can set the indication field to empty to indicate to the terminal that it can receive PDSCH transmitted in multiple time slots on both SBFD and non-SBFD symbols.

[0252] In one embodiment, when the indication field occupies 1 bit, the indication field can indicate to the terminal that PDSCH transmitted in multiple time slots can only be received on SBFD symbols, or that PDSCH transmitted in multiple time slots can be received on both SBFD symbols and non-SBFD symbols. When the indication field is empty, it can indicate to the terminal that PDSCH transmitted in multiple time slots can only be received on non-SBFD symbols.

[0253] For example, if a network device determines that it can only send PDSCH transmitted in multiple time slots to the terminal on the SBFD symbol, the 1-bit value of the indication field sent to the terminal is 1, indicating to the terminal that it can only receive PDSCH transmitted in multiple time slots on the SBFD symbol.

[0254] For example, when a network device determines that it can send PDSCH transmitted in multiple time slots to a terminal on both SBFD and non-SBFD symbols, the 1-bit value of the indication field sent to the terminal is 0, indicating to the terminal that it can receive PDSCH transmitted in multiple time slots on both SBFD and non-SBFD symbols.

[0255] For example, when a network device determines that it can send PDSCH transmitted in multiple time slots to a terminal on a non-SBFD symbol, the network device can set the indication field to empty, indicating to the terminal that it can only receive PDSCH transmitted in multiple time slots on non-SBFD symbols.

[0256] In one embodiment, when the indication field occupies 1 bit, the indication field can indicate to the terminal that PDSCH transmitted in multiple time slots can be received on both SBFD and non-SBFD symbols, or that PDSCH transmitted in multiple time slots can only be received on non-SBFD symbols. When the indication field is empty, it can indicate to the terminal that PDSCH transmitted in multiple time slots can only be received on SBFD symbols.

[0257] For example, if a network device determines that it can send PDSCH transmitted in multiple time slots to a terminal on both SBFD and non-SBFD symbols, the 1-bit value of the indication field sent to the terminal is 1, indicating that the terminal can receive PDSCH transmitted in multiple time slots on both SBFD and non-SBFD symbols.

[0258] For example, if a network device determines that it can only send PDSCH transmitted in multiple time slots to a terminal on non-SBFD symbols, the 1-bit value of the indication field sent to the terminal indicates that the terminal can only receive PDSCH transmitted in multiple time slots on non-SBFD symbols.

[0259] For example, if a network device determines that it can only send PDSCH transmitted in multiple time slots to the terminal on the SBFD symbol, the network device can set the indication field to be empty to indicate that the terminal can only receive PDSCH transmitted in multiple time slots on the SBFD symbol.

[0260] In one embodiment, when it is determined that the symbols that can be used to send PDSCH transmitted in multiple time slots to the terminal include SBFD symbols and non-SBFD symbols, the indication field indicates that the terminal can receive PDSCH transmitted in multiple time slots on both SBFD and non-SBFD symbols; and / or, when it is determined that the symbols that can be used to send PDSCH transmitted in multiple time slots to the terminal include only SBFD symbols, the indication field indicates that the terminal can only receive PDSCH transmitted in multiple time slots on SBFD symbols; and / or, when it is determined that the symbols that can be used to send PDSCH transmitted in multiple time slots to the terminal include only non-SBFD symbols, the indication field indicates that the terminal can only receive PDSCH transmitted in multiple time slots on non-SBFD symbols.

[0261] In one embodiment, when the indication field occupies 2 bits, the indication field can indicate to the terminal that it is possible to receive PDSCH transmitted in multiple time slots on both SBFD and non-SBFD symbols, or indicate to the terminal that it is possible to receive PDSCH transmitted in multiple time slots on only non-SBFD symbols, or indicate to the terminal that it is possible to receive PDSCH transmitted in multiple time slots on only SBFD symbols.

[0262] For example, if a network device determines that it can send PDSCH transmitted in multiple time slots to a terminal on both SBFD symbols and non-SBFD symbols, and the 2-bit value of the indication field sent to the terminal is 00, it indicates to the terminal that it can receive PDSCH transmitted in multiple time slots on both SBFD symbols and non-SBFD symbols.

[0263] For example, if a network device determines that it can only send PDSCH transmitted in multiple time slots to the terminal on the SBFD symbol, the 2-bit value of the indication field sent to the terminal is 01, indicating to the terminal that it can only receive PDSCH transmitted in multiple time slots on the SBFD symbol.

[0264] For example, if a network device determines that it can only send PDSCH transmitted in multiple time slots to the terminal on non-SBFD symbols, the 2-bit indication field sent to the terminal has a value of 10, indicating to the terminal that it can only receive PDSCH transmitted in multiple time slots on non-SBFD symbols.

[0265] It should be noted that the ability to send PDSCH transmitted in multiple time slots to the terminal using a certain type of symbol in this embodiment does not mean that the network device must send PDSCH transmitted in multiple time slots to the terminal using that type of symbol. Rather, it means that the network device can send PDSCH transmitted in multiple time slots to the terminal using that type of symbol, but should not send PDSCH transmitted in multiple time slots to the terminal using symbols other than that type of symbol.

[0266] For example, when a network device determines that it can send a PDSCH transmitted in multiple time slots to the terminal using both SBFD and non-SBFD symbols, it means that the network device can send the PDSCH transmitted in multiple time slots to the terminal using both SBFD and non-SBFD symbols in each time slot where the PDSCH is located. It does not mean that the network device needs to send the PDSCH transmitted in multiple time slots to the terminal using both SBFD and non-SBFD symbols in every time slot where the PDSCH is located.

[0267] For example, if a network device determines that it can only send PDSCHs transmitted in multiple time slots to the terminal on SBFD symbols, it means that the network device can send PDSCHs transmitted in multiple time slots to the terminal on SBFD symbols within each time slot where the PDSCH resides, but cannot receive PDSCHs transmitted in multiple time slots on non-SBFD symbols. It does not mean that the network device needs to send PDSCHs transmitted in multiple time slots to the terminal on SBFD symbols in every time slot where the PDSCH resides.

[0268] For example, if a network device determines that it can only send PDSCHs transmitted in multiple time slots to the terminal on non-SBFD symbols, it means that the network device can send PDSCHs transmitted in multiple time slots to the terminal on non-SBFD symbols within each time slot where the PDSCH resides, but cannot receive PDSCHs transmitted in multiple time slots on SBFD symbols. It does not mean that the network device needs to send PDSCHs transmitted in multiple time slots to the terminal on non-SBFD symbols in every time slot where the PDSCH resides.

[0269] Further determination is needed regarding which symbols in each time slot the network device sends the PDSCH transmitted across multiple time slots to the terminal. The specific determination method will be explained in subsequent embodiments.

[0270] In one embodiment, the receiving indication method further includes: when it is determined that a PDSCH can be transmitted in multiple time slots on SBFD symbols and non-SBFD symbols, and the symbols occupied by the PDSCH in the multiple time slots do not include SBFD symbols, transmitting the PDSCH on a first frequency domain resource configured in the multiple time slots.

[0271] If a network device determines that it can transmit PDSCH in multiple time slots using both SBFD and non-SBFD symbols, it can further determine whether the symbols occupied by the PDSCH in multiple time slots include SBFD symbols.

[0272] When the symbols occupied by PDSCH in multiple time slots do not include SBFD symbols, when the network device sends PDSCH transmitted in multiple time slots, there will be no situation where PDSCH is received in SBFD symbols. Therefore, the first resource FD#1 configured for PDSCH in multiple time slots will not conflict with frequency domain resources other than downlink resources. Thus, PDSCH can be sent on FD#1 in multiple time slots.

[0273] In one embodiment, the receiving indication method further includes: when it is determined that a PDSCH can be transmitted in multiple time slots on both SBFD symbols and non-SBFD symbols, and the first frequency domain resource configured for the PDSCH in the first time slot of the multiple time slots is within the downlink resource corresponding to the SBFD symbol, transmitting the PDSCH in the first time slot.

[0274] If a network device determines that it can receive PDSCH transmitted in multiple time slots on both SBFD symbols and non-SBFD symbols, it can further determine whether the first frequency domain resource FD#1 configured for the PDSCH in the first time slot of the multiple time slots contains frequency domain resources other than the downlink resources corresponding to the SBFD symbols.

[0275] When FD#1 contains frequency domain resources outside the downlink resources corresponding to the SBFD symbol, that is, when FD#1 is not located within the downlink resources corresponding to the SBFD symbol, when the network device receives PDSCH transmitted in multiple time slots in the SBFD symbol in the first time slot, FD#1 will conflict with the frequency domain resources outside the downlink resources. Therefore, it is not necessary to send PDSCH transmitted in multiple time slots to the terminal in the first time slot.

[0276] When FD#1 does not contain frequency domain resources outside the downlink resources corresponding to the SBFD symbol, that is, when FD#1 is within the downlink resources corresponding to the SBFD symbol, the network device will not conflict with the frequency domain resources outside the downlink resources when receiving PDSCH transmitted in multiple time slots in the SBFD symbol in the first time slot. Therefore, PDSCH transmitted in multiple time slots can be sent to the terminal in the first time slot.

[0277] In one embodiment, the receiving indication method further includes: when it is determined that a PDSCH can be transmitted in multiple time slots on both SBFD symbols and non-SBFD symbols, and the symbols occupied by the PDSCH in the first time slot of the multiple time slots include at least one SBFD symbol, and the first frequency domain resource configured for the PDSCH in the first time slot includes frequency domain resources located outside the downlink resources corresponding to the SBFD symbols, the PDSCH is not transmitted in the first time slot.

[0278] In one embodiment, the receiving indication method further includes: in a first time slot of a plurality of time slots, the symbols occupied by the PDSCH include uplink symbols, and the PDSCH is not transmitted in the first time slot. This embodiment can be combined with any other embodiment in this disclosure.

[0279] Whether the network device determines that it can send PDSCH transmitted in multiple time slots to the terminal using SBFD symbols and non-SBFD symbols, or only using SBFD symbols, or only using non-SBFD symbols, it can determine whether the symbols occupied by the PDSCH in the first time slot (e.g., a flexible time slot configured with uplink subbands) of the multiple time slots used to receive the PDSCH include uplink symbols. If it is determined that the symbols occupied by the PDSCH in the first time slot include uplink symbols, then FD#1 will conflict with frequency domain resources other than downlink resources. Therefore, it is not necessary to send PDSCH to the terminal in the first time slot.

[0280] In one embodiment, the receiving indication method further includes: when it is determined that a PDSCH can be transmitted in multiple time slots on both SBFD symbols and non-SBFD symbols, the symbols occupied by the PDSCH in the multiple time slots include at least one SBFD symbol, and there is an overlapping second frequency domain resource between the first frequency domain resource configured for the PDSCH and the downlink resource corresponding to the SBFD symbol in the multiple time slots, the PDSCH is transmitted on the second frequency domain resource in the multiple time slots.

[0281] In one embodiment, if the network device determines that it can send PDSCH transmitted in multiple time slots to the terminal on both SBFD symbols and non-SBFD symbols, it can further determine whether there is an overlapping second frequency domain resource FD#2 between the first frequency domain resource FD#1 configured for PDSCH in the multiple time slots and the downlink resource corresponding to the SBFD symbol.

[0282] When there is an overlapping second frequency domain resource FD#2 between the downlink resources corresponding to FD#1 and SBFD symbols, the network device can send the PDSCH transmitted in multiple time slots to the terminal in FD#2 during the multiple time slots used to receive PDSCH.

[0283] Since FD#2 is located within the downlink resources corresponding to the SBFD symbol, sending PDSCH to the terminal via FD#2, which is transmitted in multiple time slots, ensures that the frequency domain resources for receiving PDSCH on the SBFD symbol in each time slot will not conflict with the frequency domain resources outside the downlink resources.

[0284] In one embodiment, the network device, based on determining whether there is an overlapping second frequency domain resource FD#2 between the first frequency domain resource FD#1 configured for PDSCH in the first time slot of multiple time slots and the downlink resource corresponding to the SBFD symbol, can also determine whether the symbol occupied by the first PDSCH in the PDSCH transmitted in multiple time slots contains at least one SBFD symbol.

[0285] When there is an overlapping second frequency domain resource FD#2 between the downlink resources corresponding to FD#1 and SBFD symbols, and the first PDSCH in the PDSCH transmitted in multiple time slots contains at least one SBFD symbol, the network device can send the PDSCH transmitted in multiple time slots to the terminal in FD#2 during the multiple time slots used to send the PDSCH to the terminal.

[0286] In one embodiment, the network device, based on determining whether there is an overlapping second frequency domain resource FD#2 between the first frequency domain resource FD#1 configured for PDSCH in the first time slot of multiple time slots and the downlink resource corresponding to the SBFD symbol, can also determine whether the symbols occupied by all PDSCHs transmitted in multiple time slots include at least one SBFD symbol.

[0287] When there is an overlapping second frequency domain resource FD#2 between the downlink resources corresponding to FD#1 and SBFD symbols, and all PDSCH symbols in the PDSCH transmitted in multiple time slots contain at least one SBFD symbol, the network device can send the PDSCH transmitted in multiple time slots to the terminal in FD#2 during the multiple time slots used to send the PDSCH to the terminal.

[0288] In one embodiment, the receiving indication method further includes: when it is determined that a PDSCH can be transmitted in multiple time slots on SBFD symbols and non-SBFD symbols, the symbols occupied by the PDSCH in the multiple time slots include at least one SBFD symbol, and there is an overlapping second frequency domain resource between the first frequency domain resource configured for the PDSCH and the downlink resource corresponding to the SBFD symbol in the multiple time slots, transmitting the PDSCH on the second frequency domain resource on the SBFD symbol in the first time slot of the multiple time slots, and transmitting the PDSCH on the first frequency domain resource on the non-SBFD symbol in the first time slot.

[0289] In one embodiment, if the network device determines that it can send PDSCH transmitted in multiple time slots to the terminal on both SBFD symbols and non-SBFD symbols, it can further determine whether there is an overlapping second frequency domain resource FD#2 between the first frequency domain resource FD#1 configured for PDSCH in the first time slot of the multiple time slots and the downlink resource corresponding to the SBFD symbol.

[0290] When there is an overlapping second frequency domain resource FD#2 between the downlink resources corresponding to FD#1 and SBFD symbols, the network device can send PDSCH transmitted in multiple time slots to the terminal on FD#2 on the SBFD symbol in the first time slot, while it can send PDSCH transmitted in multiple time slots to the terminal on FD#1 on the non-SBFD symbol in the first time slot.

[0291] Since FD#2 is located within the downlink resources corresponding to the SBFD symbol, sending PDSCH to the terminal via multiple time slots on FD#2 on the SBFD symbol ensures that the frequency domain resources for sending PDSCH to the terminal on the SBFD symbol in each time slot do not conflict with frequency domain resources outside the downlink resources. On non-SBFD symbols, there are no frequency domain resources outside the downlink resources, so sending PDSCH via multiple time slots on FD#1 on non-SBFD symbols does not conflict with frequency domain resources outside the downlink resources and helps to ensure that frequency domain resources are fully utilized.

[0292] In one embodiment, the receiving indication method further includes: when it is determined that a PDSCH can be transmitted in multiple time slots using both SBFD symbols and non-SBFD symbols, and the symbols occupied by the PDSCH in the multiple time slots include at least one SBFD symbol, and the symbols occupied by the PDSCH in the first time slot of the multiple time slots do not include SBFD symbols, transmitting the PDSCH on a first frequency domain resource configured for the PDSCH in the first time slot, and / or, when the symbols occupied by the PDSCH in the first time slot of the multiple time slots include SBFD symbols, transmitting the PDSCH on a second frequency domain resource overlapping between the first frequency domain resource configured for the PDSCH and the downlink resource corresponding to the SBFD symbol in the first time slot.

[0293] In one embodiment, if a network device determines that it can send a PDSCH transmitted in multiple time slots to a terminal using both SBFD and non-SBFD symbols, and the symbols occupied by the PDSCH in the multiple time slots include at least one SBFD symbol, it can further determine whether the symbols occupied by the PDSCH in the first time slot of the multiple time slots include SBFD symbols.

[0294] For example, when it is determined that the symbols occupied by PDSCH in the first time slot do not include SBFD symbols, there will be no conflict between the first frequency domain resources configured for PDSCH and the frequency domain resources other than downlink resources in the first time slot. Therefore, the network device can send PDSCH to the terminal on the first frequency domain resources configured for PDSCH in the first time slot.

[0295] For example, when it is determined that the symbols occupied by PDSCH in the first time slot include SBFD symbols, the network device can further determine the second frequency domain resources that overlap between the first frequency domain resources configured for PDSCH and the downlink resources corresponding to the SBFD symbols in the first time slot. Since the second frequency domain resources are within the downlink resources corresponding to the SBFD symbols, they will not conflict with frequency domain resources outside the downlink resources. Therefore, the network device can send PDSCH to the terminal on the second frequency domain resources in the first time slot.

[0296] In one embodiment, the receiving indication method further includes: when it is determined that PDSCH transmitted in multiple time slots can be sent on SBFD symbols and non-SBFD symbols, and a third frequency domain resource for receiving PDSCH on SBFD symbols and a fourth frequency domain resource for receiving PDSCH on non-SBFD symbols are configured, sending PDSCH on the third frequency domain resource on SBFD symbols and sending PDSCH on the fourth frequency domain resource on non-SBFD symbols.

[0297] In one embodiment, when a network device determines that it can send PDSCH transmitted in multiple time slots to a terminal on SBFD symbols and non-SBFD symbols, and the symbols occupied by the PDSCH in the multiple time slots include at least one SBFD symbol, it can further determine whether the network device has configured a third frequency domain resource for receiving PDSCH on SBFD symbols and a fourth frequency domain resource for receiving PDSCH on non-SBFD symbols, wherein the third frequency domain resource does not include frequency domain resources other than the downlink resources corresponding to the SBFD symbols.

[0298] When a network device configures a terminal with third frequency domain resources for receiving PDSCH on SBFD symbols and fourth frequency domain resources for receiving PDSCH on non-SBFD symbols, since the third frequency domain resources do not include frequency domain resources other than downlink resources corresponding to SBFD symbols, the third frequency domain resources will not conflict with frequency domain resources other than downlink resources. Therefore, on the SBFD symbols occupied by PDSCH in multiple time slots used for PDSCH transmission, PDSCH for multiple time slots can be transmitted to the terminal on the third frequency domain resources.

[0299] Since there are no frequency domain resources other than downlink resources on non-SBFD symbols, the fourth frequency domain resources will not conflict with the frequency domain resources other than downlink resources. Therefore, PDSCH can be sent to the terminal on the non-SBFD symbols occupied by PDSCH in the multiple time slots used for transmitting PDSCH.

[0300] In one embodiment, the receiving indication method further includes: when it is determined that a PDSCH can be transmitted in multiple time slots on both SBFD and non-SBFD symbols, and the symbol where the PDSCH is located in the first time slot of the multiple time slots includes a non-SBFD symbol, if the downlink resource corresponding to the non-SBFD symbol is greater than or equal to the first frequency domain resource configured for the PDSCH, determining a fifth frequency domain resource in the downlink resources, and transmitting the PDSCH on the fifth frequency domain resource in the first time slot, wherein the bandwidth of the fifth frequency domain resource is equal to that of the first frequency domain resource; and / or if the downlink resource corresponding to the non-SBFD symbol is less than the first frequency domain resource configured for the PDSCH, not transmitting the PDSCH in the first time slot.

[0301] In one embodiment, when a network device determines that it can send PDSCH transmitted in multiple time slots to a terminal on both SBFD and non-SBFD symbols, and the symbol where the PDSCH is located in the first time slot of the multiple time slots includes a non-SBFD symbol, it can further determine the relationship between the downlink resources corresponding to the non-SBFD symbols and the first frequency domain resources configured for the PDSCH.

[0302] When the downlink resource corresponding to a non-SBFD symbol is greater than or equal to the first frequency domain resource configured for PDSCH, a frequency domain resource with the same bandwidth as the first frequency domain resource can be determined from the downlink resources corresponding to the non-SBFD symbol, for example, called the fifth frequency domain resource. Then, PDSCH can be transmitted on the fifth frequency domain resource in the first time slot. Since the bandwidth of the fifth frequency domain resource is equal to that of the first frequency domain resource, it is beneficial to ensure successful reception of PDSCH.

[0303] In one embodiment, the bandwidth of the first frequency domain resource can be determined first, wherein the bandwidth can be characterized by the number of RBs, for example, k1 RBs.

[0304] For example, starting from the initial RB of the active BWP corresponding to the first time slot, k1 consecutive RBs can be determined within the active BWP. If there are only k1-n RBs from the initial RB of the active BWP to the first boundary of the resource outside the downlink resource (the boundary relatively close to the initial RB), n more RBs can be determined in the downlink resource starting from the second boundary of the resource outside the downlink resource (the boundary relatively far from the initial RB). The determined k1-n RBs and n n RBs are then used as the fifth frequency domain range.

[0305] For example, the endpoint can be the ending RB of the active BWP corresponding to the first time slot, and k1 consecutive RBs can be determined in the active BWP. If there are only k1-n RBs from the ending RB of the active BWP to the second boundary of the resource outside the downlink resource (the boundary relatively close to the ending RB), n more RBs can be determined in the downlink resource starting from the first boundary of the resource outside the downlink resource (the boundary relatively far from the ending RB), and then the determined k1-n RBs and n n RBs can be used as the fifth frequency domain range.

[0306] For example, in the activated BWP, a frequency domain range with a duration of k2 consecutive RBs can be determined as the sixth frequency domain resource, and the k1 RBs overlapping the sixth frequency domain resource and the downlink resources corresponding to non-SBFD symbols can be determined as the fifth frequency domain range.

[0307] If the downlink resource corresponding to a non-SBFD symbol is less than the first frequency domain resource configured for PDSCH, then a frequency domain resource with the same bandwidth as the first frequency domain resource cannot be determined in the downlink resource corresponding to the non-SBFD symbol, and the network device does not send PDSCH to the terminal in the first time slot.

[0308] In one embodiment, the receiving indication method further includes: when it is determined that PDSCH transmitted in multiple time slots can only be sent on SBFD symbols, and there is an overlapping second frequency domain resource between the first frequency domain resource configured for PDSCH and the downlink resource corresponding to the SBFD symbol in the first time slot of the multiple time slots, if the symbols occupied by PDSCH in the first time slot include non-SBFD symbols, PDSCH is not sent in the first time slot; and / or, if the symbols occupied by PDSCH in the first time slot include SBFD symbols but do not include uplink symbols, PDSCH is sent on the second frequency domain resource in the first time slot; and / or, if the symbols occupied by PDSCH in the first time slot only include SBFD symbols, PDSCH is sent on the second frequency domain resource in the first time slot.

[0309] In one embodiment, when a network device determines that it can only send PDSCH transmitted in multiple time slots to a terminal on SBFD symbols, and there are overlapping second frequency domain resources between the first frequency domain resources configured for PDSCH and the downlink resources corresponding to the SBFD symbols in the first time slot of the multiple time slots, it can further determine whether the symbols occupied by PDSCH in the first time slot include non-SBFD symbols.

[0310] For example, if the symbols occupied by the PDSCH in the first time slot include non-SBFD symbols, sending the PDSCH to the terminal in the first time slot would result in the PDSCH occupying non-SBFD symbols, which does not comply with the limitation that PDSCH transmitted in multiple time slots can only be sent to the terminal in SBFD symbols. Therefore, the network device may choose not to send the PDSCH transmitted in multiple time slots to the terminal in the first time slot.

[0311] For example, if the symbols occupied by PDSCH in the first time slot include SBFD symbols but not uplink symbols, and if PDSCH is sent to the terminal in the first time slot, the symbols occupied by PDSCH include SBFD symbols. This can meet the limitation that PDSCH transmitted in multiple time slots can only be sent to the terminal on SBFD symbols. Therefore, the network device can send PDSCH transmitted in multiple time slots to the terminal on the second frequency domain resources in the first time slot.

[0312] For example, if the symbols occupied by PDSCH in the first time slot only include SBFD symbols, and if PDSCH is received in the first time slot, the symbols occupied by PDSCH only include SBFD symbols, which can meet the limitation that PDSCH transmitted in multiple time slots can only be sent to the terminal on SBFD symbols. Therefore, the network device can send PDSCH transmitted in multiple time slots to the terminal on the second frequency domain resources in the first time slot.

[0313] In one embodiment, the receiving indication method further includes: when it is determined that PDSCH transmitted in multiple time slots can only be transmitted on non-SBFD symbols, if the symbols occupied by PDSCH in the first time slot of the multiple time slots include SBFD symbols, not transmitting PDSCH in the first time slot; and / or, if the symbols occupied by PDSCH in the first time slot include downlink symbols and / or flexible symbols, but do not include uplink symbols, receiving PDSCH in the first time slot; and / or, if the symbols occupied by PDSCH in the first time slot only contain downlink symbols and / or flexible symbols, transmitting PDSCH in the first time slot.

[0314] In one embodiment, the network device, after determining that it can only send PDSCH transmitted in multiple time slots to the terminal on non-SBFD symbols, can further determine the symbols occupied by the PDSCH in the first time slot.

[0315] For example, if the symbols occupied by the PDSCH in the first time slot include SBFD symbols, sending the PDSCH to the terminal in the first time slot would result in the PDSCH occupying symbols including SBFD symbols, which does not comply with the limitation that PDSCH transmitted in multiple time slots can only be sent to the terminal in non-SBFD symbols. Therefore, the network device may choose not to send the PDSCH transmitted in multiple time slots to the terminal in the first time slot.

[0316] For example, if the symbols occupied by the PDSCH in the first time slot include downlink symbols and / or flexible symbols, and the PDSCH is sent to the terminal in the first time slot, the symbols occupied by the PDSCH include downlink symbols and / or flexible symbols, but do not include uplink symbols. Non-SBFD symbols include downlink symbols, flexible symbols, and uplink symbols. This can meet the limitation that PDSCH transmitted in multiple time slots can only be sent to the terminal in non-SBFD symbols. Therefore, the network device can send PDSCH transmitted in multiple time slots to the terminal in the first time slot.

[0317] For example, if the symbols occupied by the PDSCH in the first time slot only include downlink symbols and / or flexible symbols, and if the PDSCH is sent to the terminal in the first time slot, the symbols occupied by the PDSCH also only include downlink symbols and / or flexible symbols, which meets the limitation that the PDSCH transmitted in multiple time slots can only be sent to the terminal in non-SBFD symbols. Therefore, the network device can send the PDSCH transmitted in multiple time slots to the terminal in the first time slot.

[0318] Embodiments of this disclosure also propose a resource determination method, executed by a communication system, which includes a terminal and network devices.

[0319] The terminal is configured to determine, based on first information sent by the network device, a symbol that can be used to receive PDSCH transmitted in multiple time slots, wherein the symbol includes at least one of the following: SBFD symbol, non-SBFD symbol.

[0320] The network device is configured to determine, based on first information sent to the terminal, symbols that can be used to transmit PDSCH to the terminal in multiple time slots, wherein the symbols include at least one of the following: SBFD symbols and non-SBFD symbols.
