[0021] Figure 1 is a schematic diagram of an application scenario relating to an embodiment of the present disclosure.

[0022] As shown in Figure 1, embodiments of this disclosure can be applied to scenarios in which a terminal communicates with a network device, but are not limited to such scenarios. Each entity shown in Figure 1 is illustrative, and embodiments or examples of this disclosure may include all or some of the entities in Figure 1, or entities other than those in Figure 1. The number of entities is arbitrary and not limited to those in Figure 1. The connection relationships shown in Figure 1 are examples. Any entity may be connected or disconnected. Connections may be made in any way, such as direct or indirect, wired or wireless.

[0023] The terminals in the embodiments of this disclosure include, but are not limited to, mobile phones, tablet computers, wearable devices, sensors, IoT devices, and other communication devices. The terminals can communicate with network devices in 4G, 5G, 6G, and other communication systems, such as base stations and core networks.

[0024] In one embodiment, a network device can configure subbands for terminals; for example, an uplink subband for terminals can be configured in a slot, and for example, a downlink subband for terminals can be configured in a slot.

[0025] Where necessary, uplinks relating to embodiments of this disclosure may be referred to as UpLink (UL), and downlinks as DownLink (DL).

[0026] A slot configured with an uplink subband includes at least one downlink slot, a flexible slot, and an uplink slot. A slot configured with a downlink subband includes at least one uplink slot, a flexible slot, and a downlink slot.

[0027] Network devices can perform full-duplex communication in slots configured with an uplink subband and slots configured with a downlink subband. Therefore, slots configured with an uplink subband and a downlink subband are also called Subband Full Duplex (SBFD) slots. Similarly, slots without a subband configured are called non-SBFD slots. A terminal may be a terminal capable of half-duplex communication in an SBFD slot. For example, in an SBFD slot, a terminal can perform uplink transmissions but cannot receive downlink transmissions, or can receive downlink transmissions but cannot perform uplink transmissions. A symbol is called an SBFD symbol if it includes both an uplink subband and a downlink subband in the frequency domain. A slot is called an SBFD slot if selectively some symbols within it are configured as SBFD symbols. A slot is called an SBFD slot if selectively all symbols within it are configured as SBFD symbols.

[0028] Figure 2 is a schematic diagram of an SBFD slot according to an embodiment of the present disclosure.

[0029] Let's take an SBFD slot that includes a slot with an uplink subband configured as an example. As shown in Figure 2, in the five slots slot#0 to slot#4, the network device configures the uplink subband for terminals in slot#1 to slot#3. In this case, slot#1 to slot#3 are called SBFD slots, slot#0 is the downlink slot, slot#4 is the uplink slot, and slot#0 and slot#4 are called non-SBFD slots.

[0030] Among the frequency domain resources corresponding to a slot in which an uplink subband is set, downlink resources other than the uplink subband are called downlink subbands. By setting a guard band (GB) between the uplink subband and the downlink subband, the uplink subband and the downlink subband can be separated in the frequency domain.

[0031] When a network device transmits PDSCH to a terminal using multiple slots, some PDSCHs are placed in non-SBFD slots, while others are placed in SBFD slots. Therefore, a situation may arise where the primary frequency domain resources configured for the PDSCHs conflict with the uplink subband of the SBFD slot.

[0032] Of the multiple symbols included in an SBFD slot, the uplink subband can be set for all or part of the symbol. Symbols with a subband (e.g., uplink subband) set are called SBFD symbols, and symbols without a subband (e.g., uplink subband) set are called non-SBFD symbols. The first frequency domain resource set for PDSCH conflicts with the uplink subband of the SBFD slot. Specifically, the first frequency domain resource set for PDSCH in an SBFD slot conflicts with the uplink subband of the SBFD symbol.

[0033] If the first frequency domain resource configured for PDSCH conflicts with the uplink subband for SBFD symbols, the terminal may determine that it can receive PDSCH in SBFD symbols while the network device determines that the terminal cannot receive PDSCH in SBFD symbols, or vice versa. This discrepancy in the terminal's perception of whether it can receive PDSCH in SBFD symbols can lead to misunderstandings between the terminal and the network device, affecting direct communication between them. Therefore, it is necessary to clarify which symbols the terminal can receive PDSCH in.

[0034] Among these, the symbols in the embodiments of this disclosure may include OFDM (Orthogonal Frequency Division Multiplexing) symbols.

[0035] Figure 3 is a schematic flowchart of the reception determination method according to an embodiment of the present disclosure. The reception determination method according to this embodiment can be executed by a terminal.

[0036] As shown in Figure 3, the reception determination method may include the following steps.

[0037] In step S301, based on first information transmitted by the network device, symbols available for receiving a physical downlink shared channel (PDSCH) transmitted across multiple slots are determined. Here, the symbols include at least one of subband full-duplex SBFD symbols and non-SBFD symbols.

[0038] It should be noted that the embodiments shown in Figure 3 may be carried out independently or in combination with at least one other embodiment of the present disclosure. Specific choices can be made as needed, and the disclosure is not limited thereto.

[0039] In one embodiment, a terminal can receive first information transmitted by a network device and then, based on the first information, determine the symbols available for receiving a PDSCH transmitted in multiple slots. For example, it may be determined that the PDSCH transmitted in multiple slots can be received only with SBFD symbols, or only with non-SBFD symbols, or with both SBFD and non-SBFD symbols. This ensures that the symbols available for receiving the PDSCH transmitted in multiple slots, as determined by the terminal, match the network device's understanding, thereby ensuring the quality of communication between the network device and the terminal.

[0040] The embodiments of this disclosure primarily demonstrate technical solutions for cases where the SBFD symbol is a symbol with an uplink subband configured. However, the technical solutions of this disclosure are also applicable when the SBFD symbol is a symbol with a downlink subband configured.

[0041] In one embodiment, the PDSCH transmitted through multiple slots is The system includes at least one of the following: PDSCH repetition and semi-persistent scheduling (SPS) PDSCH.

[0042] Multiple PDSCHs scheduled by a single Downlink Control Information (DCI) are called Multiple PDSCH scheduled by single DCI.

[0043] Of these, SPS PDSCH may further include SPS PDSCH with repetition and SPS PDSCH without repetition.

[0044] In the case of SPS PDSCH with repetition, a network device can transmit multiple PDSCHs in an SPS resource, and each PDSCH may be transmitted repeatedly. Repeated transmission of a PDSCH is sometimes called a group. In this embodiment, a PDSCH transmitted in multiple slots may contain one group of PDSCHs in SPS PDSCH with repetition, or it may contain all groups of PDSCHs in SPS PDSCH with repetition.

[0045] In one embodiment, the first information includes at least one of frequency domain resource information and an instruction field.

[0046] The network device, through the first piece of information, indicates the symbols available for a terminal to receive a DSCH transmitted across multiple slots. The indication methods include, but are not limited to, explicit and implicit indications.

[0047] For example, if an explicit instruction method is employed, the first information transmitted by the network device may include an instruction field. The instruction field may be a newly added field in the signaling, or it may be an existing field in the multiplexed signaling (e.g., a field consisting of reserved bits). The signaling includes at least one of the following: Radio Resource Control (RRC) signaling, DCI, and Media Access Control Element (MAC CE). The terminal receives the instruction field in the signaling according to the instruction and can determine the symbol available to receive the PDSCH transmitted in multiple slots, as instructed by the network device.

[0048] For example, if an implicit instruction method is employed, the first information transmitted by the network device may include frequency domain resource information. The terminal can determine the frequency domain resources to be set up for the PDSCH transmitted in multiple slots according to the frequency domain resource information, and further determine the symbols available to receive the PDSCH transmitted in multiple slots, as instructed by the network device, according to the relationship between the frequency domain resources set up for the PDSCH transmitted in multiple slots and the downlink resources corresponding to the SBFD symbols.

[0049] It should be noted that in the embodiments of this disclosure, the downlink resource corresponding to the SBFD symbol may include a downlink subband, or it may include both a downlink subband and a guard band.

[0050] In one embodiment, the step of determining symbols available for receiving PDSCH transmitted in multiple slots based on first information transmitted by a network device is: When frequency domain resource information transmitted by a network device sets up a frequency domain resource for a PDSCH within a downlink resource corresponding to an SBFD symbol, the step of determining whether the PDSCH transmitted in multiple slots can be received with SBFD and non-SBFD symbols, and When configuring the frequency domain resources of a PDSCH such that the frequency domain resource information transmitted by a network device includes frequency domain resources other than downlink resources corresponding to SBFD symbols, the step of determining whether the PDSCH transmitted in multiple slots can be received only as SBFD symbols or non-SBFD symbols, It includes at least one of the following.

[0051] Figure 4A is a schematic diagram of a frequency domain resource according to an embodiment of the present disclosure. Figure 4B is a schematic diagram of another frequency domain resource according to an embodiment of the present disclosure.

[0052] For example, one slot contains 14 symbols. The uplink subband is set to symbols #6 to #10. The symbols that the PDSCH must occupy in an SBFD slot include symbols #3 to #8. Symbols #3 to #5 do not have an uplink subband set and are non-SBFD symbols, while symbols #6 to #8 are SBFD symbols.

[0053] As shown in Figure 4A, the frequency domain resource that the network device has set to a PDSCH transmitted across multiple slots is FD#1, and FD#1 is located within a downlink resource corresponding to an SBFD symbol (e.g., a downlink subband, or a downlink subband and a guard band). Based on the frequency domain resource information, the terminal can determine that the frequency domain resource set to a PDSCH transmitted across multiple slots is FD#1. If the terminal determines that FD#1 is located within a downlink resource corresponding to an SBFD symbol, it can determine that the network device is instructing the terminal to receive the PDSCH transmitted across multiple slots with both SBFD and non-SBFD symbols, for example, that the network device is instructing the terminal to receive the PDSCH transmitted across multiple slots with symbols #3 to #8.

[0054] As shown in Figure 4B, the frequency domain resource that the network device has set for the PDSCH transmitted across multiple slots is FD#1, and FD#1 includes frequency domain resources other than the downlink resource corresponding to the SBFD symbol. Based on the frequency domain resource information, the terminal can determine that the frequency domain resource set for the PDSCH transmitted across multiple slots is FD#1. If the terminal determines that FD#1 includes frequency domain resources other than the downlink resource corresponding to the SBFD symbol (for example, if there is a resource collision between FD#1 and the frequency domain resource other than the downlink resource in Figure 4B), the terminal can determine that the network device has instructed the terminal to receive the PDSCH transmitted across multiple slots using only non-SBFD symbols, and for example, it can determine that the PDSCH transmitted across multiple slots can be received using only non-SBFD symbols (symbols #3 to #5).

[0055] Furthermore, if FD#1 includes frequency domain resources other than downlink resources corresponding to SBFD symbols, the terminal may also determine that the network device has instructed the terminal to receive PDSCHs transmitted in multiple slots using only SBFD symbols. For example, if the symbol on which the first PDSCH among multiple PDSCHs is located contains an SBFD symbol, the terminal may determine that PDSCHs transmitted in multiple slots can be received using only SBFD symbols, or if all symbols on which the first PDSCH among multiple PDSCHs is located contain SBFD symbols, the terminal may determine that PDSCHs transmitted in multiple slots can be received using only SBFD symbols. The first PDSCH refers to the PDSCH transmitted in the first slot among multiple slots.

[0056] In one embodiment, the step of determining that PDSCH transmitted in multiple slots can be received only as SBFD symbols or non-SBFD symbols is: If the symbol on which the first PDSCH among the PDSCHs transmitted in multiple slots is located contains an SBFD symbol, the step of determining that the PDSCHs transmitted in multiple slots can be received with only SBFD symbols, and If all symbols on which the first PDSCH is located among PDSCHs transmitted in multiple slots are non-SBFD symbols, then it is determined that the PDSCHs transmitted in multiple slots can be received with only non-SBFD symbols. It includes at least one of the following.

[0057] For example, a terminal can determine which slot contains the first PDSCH among multiple PDSCHs being transmitted in those slots, and determine the symbol in which the first PDSCH in that slot is located. If the symbol in which the first PDSCH in that slot is located contains an SBFD symbol, the terminal can determine that the PDSCH transmitted in multiple slots can be received using only SBFD symbols. If all the symbols in which the first PDSCH in that slot is located are non-SBFD symbols, the terminal can determine that the PDSCH transmitted in multiple slots can be received using only non-SBFD symbols.

[0058] In one embodiment, the step of determining that PDSCH transmitted in multiple slots can be received only as SBFD symbols or non-SBFD symbols is: If all symbols on which the first PDSCH is located among PDSCHs transmitted in multiple slots are SBFD symbols, the step of determining that the PDSCHs transmitted in multiple slots can be received with only SBFD symbols, and If the symbol on which the first PDSCH among the PDSCHs transmitted in multiple slots is located contains a non-SBFD symbol, the step of determining that the PDSCHs transmitted in multiple slots can be received with only non-SBFD symbols, It includes at least one of the following.

[0059] For example, a terminal can determine which slot contains the first PDSCH among multiple PDSCHs being transmitted in those slots, and then determine the symbol in which the first PDSCH is located in that slot. If all the symbols in which the first PDSCH is located in that slot are SBFD symbols, the terminal can determine that the PDSCH transmitted in multiple slots can be received using only SBFD symbols. Also, if the symbols in which the first PDSCH is located in that slot include non-SBFD symbols, the terminal can determine that the PDSCH transmitted in multiple slots can be received using only non-SBFD symbols.

[0060] Note that the number of slots in which the PDSCH is located shown in the attached diagram is merely an example, and the PDSCH may be transmitted in slots other than those shown in the attached diagram.

[0061] Figure 5 is a schematic flowchart of another reception determination method according to an embodiment of the present disclosure. The reception determination method according to this embodiment can be performed by a terminal. As shown in Figure 5, the step of determining a symbol available for receiving a PDSCH transmitted in multiple slots, based on first information transmitted by a network device, includes the following steps:

[0062] In step S501, if frequency domain resources are set for receiving PDSCH with SBFD symbols and frequency domain resources are set for receiving PDSCH with non-SBFD symbols, it is determined that PDSCH transmitted in multiple slots can be received with both SBFD and non-SBFD symbols.

[0063] It should be noted that the embodiments shown in Figure 5 may be carried out independently or in combination with at least one other embodiment of the present disclosure. Specific choices can be made as needed, and the disclosure is not limited thereto.

[0064] In one embodiment, the first information transmitted by the network device may include frequency domain resource information. The frequency domain resource information may be set to a frequency domain resource for receiving PDSCH with an SBFD symbol and a frequency domain resource for receiving PDSCH with a non-SBFD symbol. Here, the frequency domain resource for receiving PDSCH with an SBFD symbol does not include any frequency domain resources other than the downlink resource corresponding to the SBFD symbol.

[0065] In this case, the terminal can determine, based on the frequency domain resource information, that frequency domain resources are configured for receiving PDSCH with SBFD symbols and for receiving PDSCH with non-SBFD symbols, and further determine that PDSCH transmitted in multiple slots can be received with both SBFD and non-SBFD symbols.

[0066] For example, a non-SBFD symbol can receive a PDSCH using the frequency domain resources intended for receiving PDSCHs with non-SBFD symbols, and an SBFD symbol can receive a PDSCH using the frequency domain resources intended for receiving PDSCHs with SBFD symbols.

[0067] In one embodiment, the instruction field occupies one or two bits. It should be noted that the number of bits occupied by the instruction field is not limited to one or two, but may be any other number. In the following embodiments, the technical solutions of this disclosure will be explained mainly by giving examples of cases where the instruction field occupies one bit and cases where the instruction field occupies two bits.

[0068] In one embodiment, the step of determining symbols available for receiving PDSCH transmitted in multiple slots based on first information transmitted by a network device is:

[0069] If the instruction field indicates that a PDSCH transmitted in multiple slots can be received with SBFD symbols and non-SBFD symbols, the steps include determining that a PDSCH transmitted in multiple slots can be received with SBFD symbols and non-SBFD symbols, and If the instruction field indicates that PDSCH transmitted in multiple slots can be received only as SBFD symbols or non-SBFD symbols, the step of determining that PDSCH transmitted in multiple slots can be received only as SBFD symbols or non-SBFD symbols, It includes at least one of the following.

[0070] In one embodiment, if the instruction field occupies 1 bit, the instruction field can indicate that a PDSCH transmitted in multiple slots can be received with both SBFD and non-SBFD symbols, or that a PDSCH transmitted in multiple slots can be received with either only SBFD symbols or only non-SBFD symbols.

[0071] For example, if the value of the instruction field occupying one bit is 1, it indicates that PDSCH transmitted across multiple slots can be received with both SBFD and non-SBFD symbols. If a terminal determines that the value of the instruction field occupying one bit is 1, it can determine that PDSCH transmitted across multiple slots can be received with both SBFD and non-SBFD symbols.

[0072] For example, if the value of the indicator field occupying one bit is 0, PDSCH transmitted across multiple slots can be received only as SBFD symbols or non-SBFD symbols. If a terminal determines that the value of the indicator field occupying one bit is 0, it can determine that PDSCH transmitted across multiple slots can be received only as SBFD symbols or non-SBFD symbols.

[0073] In one embodiment, determining that PDSCH transmitted in multiple slots can be received only as SBFD symbols or non-SBFD symbols means that If the symbol on which the first PDSCH is located among PDSCHs transmitted in multiple slots includes an SBFD symbol, it is determined that the PDSCHs transmitted in multiple slots can be received with only SBFD symbols, and If all symbols on which the first PDSCH is located in a PDSCH transmitted through multiple slots are non-SBFD symbols, then it is determined that the PDSCH transmitted through multiple slots can be received with only non-SBFD symbols. It includes at least one of the following.

[0074] For example, a terminal can determine which slot contains the first PDSCH among multiple PDSCHs being transmitted in those slots, and then determine the symbol on which the first PDSCH in that slot is located. If the symbol on which the first PDSCH in a slot is located contains an SBFD symbol, the terminal can determine that the PDSCH transmitted in multiple slots can be received using only SBFD symbols. Also, if all the symbols on which the first PDSCH in a slot is located are non-SBFD symbols, the terminal can determine that the PDSCH transmitted in multiple slots can be received using only non-SBFD symbols.

[0075] In one embodiment, the step of determining that PDSCH transmitted in multiple slots can be received only as SBFD symbols or non-SBFD symbols is: If all symbols on which the first PDSCH is located among PDSCHs transmitted in multiple slots are SBFD symbols, the step of determining that the PDSCHs transmitted in multiple slots can be received with only SBFD symbols, and If the symbol on which the first PDSCH among the PDSCHs transmitted in multiple slots is located contains a non-SBFD symbol, the step of determining that the PDSCHs transmitted in multiple slots can be received with only non-SBFD symbols, It includes at least one of the following.

[0076] For example, a terminal can determine which slot contains the first PDSCH among multiple PDSCHs being transmitted in those slots, and determine the symbols in which the first PDSCH is located in that slot. If all the symbols in which the first PDSCH is located in that slot are SBFD symbols, the terminal can determine that the PDSCH transmitted in multiple slots can only be received as SBFD symbols. If the symbols in which the first PDSCH is located in that slot include non-SBFD symbols, the terminal can determine that the PDSCH transmitted in multiple slots can only be received as non-SBFD symbols.

[0077] In one embodiment, the step of determining that PDSCH transmitted in multiple slots can be received only as SBFD symbols or non-SBFD symbols is: If all symbols on which the first PDSCH is located among PDSCHs transmitted in multiple slots are SBFD symbols, then it is determined that the PDSCHs transmitted in multiple slots can be received only as SBFD symbols, and If all symbols on which the first PDSCH is located are non-SBFD symbols among the PDSCHs transmitted in multiple slots, the step of determining that the PDSCHs transmitted in multiple slots can be received with only non-SBFD symbols, It includes at least one of the following.

[0078] For example, a terminal can determine which slot contains the first PDSCH among multiple PDSCHs being transmitted in those slots, and then determine the symbol in which the first PDSCH is located in that slot. If all the symbols in which the first PDSCH is located in a slot are SBFD symbols, the terminal can determine that PDSCHs transmitted in multiple slots can only be received as SBFD symbols. Also, if all the symbols in which the first PDSCH is located in a slot are non-SBFD symbols, the terminal can determine that PDSCHs transmitted in multiple slots can only be received as non-SBFD symbols.

[0079] In one embodiment, the step of determining symbols available for receiving PDSCH transmitted in multiple slots based on first information transmitted by a network device is: If the instruction field is a first value, a second value, or the instruction field is empty, then if it is indicated that PDSCH transmitted in multiple slots can be received only as SBFD symbols, then it is determined that PDSCH transmitted in multiple slots can be received only as SBFD symbols. If the indicator field is a first value, a second value, or the indicator field is empty, then it is determined that the PDSCH transmitted in multiple slots can be received only as non-SBFD symbols, and If the instruction field has a first value, a second value, or the field is empty, then it is determined that the PDSCH transmitted in multiple slots can be received with SBFD symbols and non-SBFD symbols. It includes at least one of the following.

[0080] It is understood that the content indicated by the first information differs depending on whether the indicator field has a first value, a second value, or is empty. The following describes, through several embodiments, what the content indicated by the first information is when the indicator field has a first value, a second value, and is empty. However, the correspondence between what is indicated by the first information and the indicator field taking a first value, a second value, and being empty is not limited to the following embodiments.

[0081] In one embodiment, if the instruction field occupies 1 bit, the instruction field can indicate that PDSCH transmitted in multiple slots can be received only as SBFD symbols, or that PDSCH transmitted in multiple slots can be received only as non-SBFD symbols; if the instruction field is empty, it can indicate that PDSCH transmitted in multiple slots can be received as both SBFD and non-SBFD symbols.

[0082] For example, if the value of the instruction field occupying one bit is 1, it indicates that PDSCH transmitted across multiple slots can only be received as SBFD symbols. When a terminal determines that the value of the instruction field occupying one bit is 1, it can determine that PDSCH transmitted across multiple slots can only be received as SBFD symbols.

[0083] For example, if the value of the 1-bit instruction field is 0, it indicates that PDSCH transmitted across multiple slots can only be received with non-SBFD symbols. If a terminal determines that the value of the 1-bit instruction field is 0, it can determine that PDSCH transmitted across multiple slots can only be received with non-SBFD symbols.

[0084] For example, if the terminal determines that the instruction field is empty, it can determine that PDSCH transmitted through multiple slots can be received with both SBFD and non-SBFD symbols.

[0085] In one embodiment, if the instruction field occupies 1 bit, the instruction field can indicate that a PDSCH transmitted in multiple slots can be received only as an SBFD symbol, or that a PDSCH transmitted in multiple slots can be received as both an SBFD symbol and a non-SBFD symbol. If the instruction field is empty, it can indicate that a PDSCH transmitted in multiple slots can be received only as a non-SBFD symbol.

[0086] For example, if the value of the instruction field occupying one bit is 1, it indicates that PDSCH transmitted across multiple slots can only be received as SBFD symbols. When a terminal determines that the value of the instruction field occupying one bit is 1, it can determine that PDSCH transmitted across multiple slots can only be received as SBFD symbols.

[0087] For example, if the value of the 1-bit instruction field is 0, it indicates that PDSCH transmitted across multiple slots can only be received as SBFD and non-SBFD symbols. If a terminal determines that the value of the 1-bit instruction field is 0, it can determine that PDSCH transmitted across multiple slots can only be received as SBFD and non-SBFD symbols.

[0088] For example, if the terminal determines that the instruction field is empty, it can determine that PDSCH transmitted across multiple slots can only be received with non-SBFD symbols.

[0089] In one embodiment, if the instruction field occupies 1 bit, the instruction field can indicate that a PDSCH transmitted in multiple slots can be received with both SBFD and non-SBFD symbols, or that a PDSCH transmitted in multiple slots can be received with only non-SBFD symbols; if the instruction field is empty, it can indicate that a PDSCH transmitted in multiple slots can be received with only SBFD symbols.

[0090] For example, if the value of the instruction field occupying one bit is 1, it indicates that PDSCH transmitted across multiple slots can be received with both SBFD and non-SBFD symbols. If a terminal determines that the value of the instruction field occupying one bit is 1, it can determine that PDSCH transmitted across multiple slots can be received with both SBFD and non-SBFD symbols.

[0091] For example, if the value of the 1-bit instruction field is 0, it indicates that PDSCH transmitted across multiple slots can only be received with non-SBFD symbols. If a terminal determines that the value of the 1-bit instruction field is 0, it can determine that PDSCH transmitted across multiple slots can only be received with non-SBFD symbols.

[0092] For example, if the terminal determines that the instruction field is empty, it can determine that PDSCH transmitted across multiple slots can only be received with SBFD symbols.

[0093] In one embodiment, the step of determining symbols available for receiving PDSCH transmitted in multiple slots based on first information transmitted by a network device is: If the instruction field indicates that a PDSCH transmitted in multiple slots can be received with both SBFD and non-SBFD symbols, the step of determining that a PDSCH transmitted in multiple slots can be received with both SBFD and non-SBFD symbols, If the instruction field indicates that PDSCH transmitted in multiple slots can be received only as SBFD symbols, the step of determining that PDSCH transmitted in multiple slots can be received only as SBFD symbols, and If the instruction field indicates that PDSCH transmitted in multiple slots can be received only as non-SBFD symbols, the step of determining that PDSCH transmitted in multiple slots can be received only as non-SBFD symbols, It includes at least one of the following.

[0094] In one embodiment, if the instruction field occupies 2 bits, the instruction field can indicate that a PDSCH transmitted in multiple slots can be received with both SBFD and non-SBFD symbols, or that a PDSCH transmitted in multiple slots can be received only with non-SBFD symbols, or that a PDSCH transmitted in multiple slots can be received only with SBFD symbols.

[0095] For example, if the value of the two-bit instruction field is 00, it indicates that PDSCH transmitted across multiple slots can be received with both SBFD and non-SBFD symbols. When a terminal determines that the value of the two-bit instruction field is 00, it can determine that PDSCH transmitted across multiple slots can be received with both SBFD and non-SBFD symbols.

[0096] For example, if the value of the two-bit instruction field is 01, it indicates that PDSCH transmitted across multiple slots can only be received as SBFD symbols. When a terminal determines that the value of the two-bit instruction field is 01, it can determine that PDSCH transmitted across multiple slots can only be received as SBFD symbols.

[0097] For example, if the value of the two-bit instruction field is 10, it indicates that PDSCH transmitted across multiple slots can only be received as non-SBFD symbols. If a terminal determines that the value of the two-bit instruction field is 10, it can determine that PDSCH transmitted across multiple slots can only be received as non-SBFD symbols.

[0098] In the embodiments of this disclosure, the ability to receive PDSCH transmitted in multiple slots using a certain type of symbol does not mean that the terminal must receive PDSCH transmitted in multiple slots using this type of symbol, but rather that the terminal can receive PDSCH transmitted in multiple slots using this type of symbol, but cannot receive PDSCH transmitted in multiple slots using symbols other than this type of symbol.

[0099] For example, when a terminal determines that it can receive a PDSCH transmitted in multiple slots with both SBFD and non-SBFD symbols, it does not mean that the terminal must receive the PDSCH transmitted in multiple slots with both SBFD and non-SBFD symbols in each slot where the PDSCH is located. Rather, it means that the terminal is capable of receiving the PDSCH transmitted in multiple slots with both SBFD and non-SBFD symbols in each slot where the PDSCH is located.

[0100] For example, when a terminal determines that it can receive a PDSCH transmitted across multiple slots using only SBFD symbols, it does not mean that the terminal must receive the PDSCH transmitted across multiple slots using SBFD symbols in each slot where the PDSCH is located. Rather, it means that the terminal can receive the PDSCH transmitted across multiple slots using SBFD symbols in each slot where the PDSCH is located, but cannot receive the PDSCH transmitted across multiple slots using non-SBFD symbols.

[0101] For example, when a terminal determines that it can receive a PDSCH transmitted in multiple slots using only non-SBFD symbols, it does not mean that the terminal must receive the PDSCH transmitted in multiple slots using only non-SBFD symbols in each slot where the PDSCH is located. Rather, it means that the terminal can receive the PDSCH transmitted in multiple slots using only non-SBFD symbols in each slot where the PDSCH is located, but cannot receive the PDSCH transmitted in multiple slots using only SBFD symbols.

[0102] It is further necessary to determine which symbol in each slot where the PDSCH is located the terminal will receive the PDSCH transmitted across multiple slots. The specific method for making this determination will be described in subsequent embodiments.

[0103] In one embodiment, the reception determination method further includes the step of receiving the PDSCH in a first frequency domain resource set up for the PDSCH in the multiple slots if it is determined that the PDSCH transmitted in multiple slots can be received with SBFD symbols and non-SBFD symbols, and the symbols occupied by the PDSCH in the multiple slots do not include SBFD symbols.

[0104] If the terminal determines that PDSCH transmitted across multiple slots can be received with both SBFD and non-SBFD symbols, it can further determine whether the symbols occupied by the PDSCH across those multiple slots include SBFD symbols.

[0105] If the symbols occupied by the PDSCH in multiple slots do not include the SBFD symbol, then when a terminal receives the PDSCH transmitted in multiple slots, the situation of receiving the PDSCH with the SBFD symbol will not occur. Therefore, the first resource FD#1 configured for the PDSCH in multiple slots will not conflict with frequency domain resources other than downlink resources. Consequently, the PDSCH can be received in multiple slots using FD#1. Correspondingly, a network device can transmit the PDSCH transmitted in multiple slots using FD#1 to terminals in multiple slots.

[0106] Figure 6 is a schematic flowchart of another reception determination method according to an embodiment of the present disclosure. The reception determination method shown in this embodiment can be performed by a terminal. As shown in Figure 6, the reception determination method further includes the following steps.

[0107] In step S601, if it is determined that the PDSCH transmitted in multiple slots can be received with SBFD symbols and non-SBFD symbols, and the symbols occupied by the PDSCH in the first slot of the multiple slots include at least one SBFD symbol, and the first frequency domain resource set up for the PDSCH in the first slot includes a frequency domain resource other than the downlink resource corresponding to the SBFD symbol, then the PDSCH is not received in the first slot.

[0108] It should be noted that the embodiment shown in Figure 6 can be implemented independently or in combination with at least one other embodiment of the present disclosure. Specific choices can be made as needed, and the disclosure is not limited. Furthermore, the first frequency domain resources set in each slot of a PDSCH transmitted through multiple slots may be identical. The first slot can refer to any slot among the multiple slots.

[0109] In one embodiment, the reception determination method further includes the step of receiving the PDSCH in the first slot if it is determined that the PDSCH transmitted in multiple slots can be received with SBFD symbols and non-SBFD symbols, and if the first frequency domain resource set for the PDSCH in the first slot of the multiple slots is located within the downlink resources corresponding to the SBFD symbols.

[0110] In one embodiment, if the terminal determines that the PDSCH transmitted in multiple slots can be received with 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 of the multiple slots includes frequency domain resources other than downlink resources corresponding to SBFD symbols.

[0111] If FD#1 includes frequency domain resources other than the downlink resource corresponding to the SBFD symbol, i.e., if FD#1 is not located within the downlink resource corresponding to the SBFD symbol, then when the terminal receives a PDSCH transmitted in multiple slots with the SBFD symbol in the first slot, FD#1 will collide with a frequency domain resource other than the downlink resource, and therefore does not need to receive the PDSCH transmitted in multiple slots in the first slot. Consequently, the network device does not need to send the PDSCH transmitted in multiple slots to the terminal in the first slot.

[0112] If FD#1 does not contain any frequency domain resources other than the downlink resource corresponding to the SBFD symbol, that is, if FD#1 is located within the downlink resource corresponding to the SBFD symbol, then when a terminal receives a PDSCH transmitted in multiple slots with the SBFD symbol in the first slot, FD#1 will not conflict with any frequency domain resources other than the downlink resource, and therefore the PDSCH can be received in the first slot. Thus, the network device can transmit a PDSCH transmitted in multiple slots to the terminal in the first slot.

[0113] In one embodiment, the reception determination method further includes the step of not receiving the PDSCH in the first slot if the symbols occupied by the PDSCH in the first slot of a plurality of slots include an uplink symbol. This embodiment can be combined with other embodiments of the present disclosure.

[0114] Regardless of whether the terminal decides to receive PDSCH transmitted across multiple slots with both SBFD and non-SBFD symbols, to receive PDSCH transmitted across multiple slots with only SBFD symbols, or to receive PDSCH transmitted across multiple slots with only non-SBFD symbols, it can determine whether the symbols occupied by the PDSCH in the first of the multiple slots used to receive the PDSCH include uplink symbols. If it is determined that the symbols occupied by the PDSCH in the first slot include uplink symbols, then FD#1 will conflict with frequency domain resources other than downlink resources, and therefore the PDSCH does not need to be received in the first slot. Consequently, the network device does not need to transmit PDSCH transmitted across multiple slots to the terminal in the first slot.

[0115] Figure 7 is a schematic flowchart of another reception determination method according to an embodiment of the present disclosure. The reception determination method according to this embodiment can be performed by a terminal. As shown in Figure 7, the reception determination method further includes the following steps.

[0116] In step S701, if it is determined that the PDSCH transmitted in multiple slots can be received with SBFD symbols and non-SBFD symbols, and the symbols occupied by the PDSCH in multiple slots include at least one SBFD symbol, and there is a second frequency domain resource that overlaps between the first frequency domain resource set for the PDSCH in multiple slots and the downlink resource corresponding to the SBFD symbol, then the PDSCH is received in the second frequency domain resource in multiple slots.

[0117] It should be noted that the embodiment shown in Figure 7 can be implemented independently or in combination with at least one other embodiment of the present disclosure. Specific implementations can be selected as needed and are not limited by the present disclosure. This embodiment can be applied when the first information is based on express instructions.

[0118] In one embodiment, if the terminal determines that PDSCH transmitted in multiple slots can be received with both SBFD and non-SBFD symbols, it can further determine whether there is a second frequency domain resource FD#2 that overlaps between a first frequency domain resource FD#1 configured for PDSCH in multiple slots and the downlink resource corresponding to the SBFD symbol.

[0119] If there is a second frequency domain resource, FD#2, that overlaps between FD#1 and the downlink resource corresponding to the SBFD symbol, the terminal can receive the PDSCH transmitted in multiple slots via FD#2 in multiple slots for receiving the PDSCH.

[0120] Since FD#2 is located within the downlink resource corresponding to the SBFD symbol, receiving PDSCH transmitted across multiple slots with FD#2 ensures that the frequency domain resources for receiving PDSCH with each slot's SBFD symbol do not conflict with frequency domain resources other than the downlink resource. Similarly, a network device can transmit PDSCH transmitted across multiple slots to a terminal using only the FD#2 of multiple slots.

[0121] Figure 8 is a schematic flowchart of another reception determination method according to an embodiment of the present disclosure. The reception determination method according to this embodiment can be performed by a terminal. As shown in Figure 8, the reception determination method further includes the following steps.

[0122] In step S801, if it is determined that a PDSCH transmitted in multiple slots can be received with SBFD symbols and non-SBFD symbols, and the symbols occupied by the PDSCH in multiple slots include at least one SBFD symbol, and there is an overlapping second frequency domain resource between a first frequency domain resource set for the PDSCH and the downlink resource corresponding to the SBFD symbol in multiple slots, then the PDSCH is received with the second frequency domain resource for the SBFD symbol in the first slot of the multiple slots, and the PDSCH is received with the first frequency domain resource for the non-SBFD symbol in the first slot.

[0123] It should be noted that the embodiments shown in Figure 8 may be carried out independently or in combination with at least one other embodiment of the present disclosure. Specific choices can be made as needed, and the disclosure is not limited thereto.

[0124] In one embodiment, if the terminal determines that PDSCH transmitted in multiple slots can be received with SBFD symbols and non-SBFD symbols, it can further determine whether there is an overlapping second frequency domain resource FD#2 between a first frequency domain resource FD#1 configured for PDSCH in a first slot of the multiple slots and the downlink resource corresponding to the SBFD symbol.

[0125] If there is an overlapping second frequency domain resource FD#2 between FD#1 and the downlink resource corresponding to the SBFD symbol, the terminal can receive a PDSCH transmitted in multiple slots via FD#2 in the SBFD symbol of the first slot, and can receive a PDSCH transmitted in multiple slots via FD#1 in the non-SBFD symbol of the first slot.

[0126] Since FD#2 is located within the downlink resource corresponding to the SBFD symbol, receiving PDSCH transmitted across multiple slots via FD#2 in the SBFD symbol ensures that the frequency domain resources for receiving PDSCH in each slot of the SBFD symbol do not conflict with frequency domain resources other than the downlink resource. However, since non-SBFD symbols do not have frequency domain resources other than the downlink resource, PDSCH transmitted across multiple slots can be received via FD#1 in the non-SBFD symbol, ensuring that the frequency domain resources are fully utilized without conflicting with frequency domain resources other than the downlink resource. Accordingly, the network device can transmit PDSCH transmitted across multiple slots to the terminal using only FD#2 in the SBFD symbol of the first slot, and transmit PDSCH transmitted across multiple slots to the terminal using FD#1 in the non-SBFD symbol of the first slot.

[0127] Figure 9 is a schematic flowchart of another reception determination method according to an embodiment of the present disclosure. The reception determination method according to this embodiment can be performed by a terminal. As shown in Figure 9, the reception determination method further includes the following steps.

[0128] In step S901, if it is determined that the PDSCH transmitted in multiple slots can be received with SBFD symbols and non-SBFD symbols, and the symbols occupied by the PDSCH in multiple slots include at least one SBFD symbol, then if the symbols occupied by the PDSCH in the first slot of the multiple slots do not include an SBFD symbol, the PDSCH is received in the first frequency domain resource configured for the PDSCH in the first slot, and / or, if the symbols occupied by the PDSCH in the first slot of the multiple slots include an SBFD symbol, the PDSCH is received in the second frequency domain resource that overlaps between the first frequency domain resource configured for the PDSCH in the first slot and the downlink resource corresponding to the SBFD symbol.

[0129] It should be noted that the embodiment shown in Figure 9 can be implemented independently or in combination with at least one other embodiment of the present disclosure. Specific choices can be made as needed and are not limited by the present disclosure.

[0130] In one embodiment, the terminal can determine that a PDSCH transmitted in multiple slots can be received with SBFD symbols and non-SBFD symbols, and that the symbols occupied by the PDSCH in multiple slots include at least one SBFD symbol, and further determine whether the symbols occupied by the PDSCH in a first slot among the multiple slots include an SBFD symbol.

[0131] For example, if it is determined that the symbols occupied by the PDSCH in the first slot do not include SBFD symbols, the first frequency domain resource set up for the PDSCH in the first slot will not conflict with any frequency domain resources other than the downlink resource, and the terminal can receive the PDSCH using the first frequency domain resource set up for the PDSCH in the first slot.

[0132] For example, if it is determined that the symbols occupied by the PDSCH in the first slot include SBFD symbols, the terminal can further determine a second frequency domain resource that overlaps with the first frequency domain resource set up for the PDSCH in the first slot and the downlink resource corresponding to the SBFD symbols. Since the second frequency domain resource is within the downlink resource corresponding to the SBFD symbols and does not conflict with any other frequency domain resources, the terminal can receive the PDSCH in the first slot using the second frequency domain resource.

[0133] Figure 10 is a schematic flowchart of another reception determination method according to an embodiment of the present disclosure. The reception determination method according to this embodiment can be performed by a terminal. As shown in Figure 10, the reception determination method further includes the following steps.

[0134] In step S1001, if it is determined that the PDSCH transmitted in multiple slots can be received by both SBFD symbols and non-SBFD symbols, and a third frequency domain resource for receiving the PDSCH with SBFD symbols and a fourth frequency domain resource for receiving the PDSCH with non-SBFD symbols are set, then the PDSCH is received by the third frequency domain resource with SBFD symbols and by the fourth frequency domain resource with non-SBFD symbols.

[0135] It should be noted that the embodiments shown in Figure 10 may be carried out independently or in combination with at least one other embodiment of the present disclosure. Specific choices can be made as needed, and the disclosure is not limited thereto.

[0136] In one embodiment, if a terminal determines that a PDSCH transmitted in multiple slots can be received with both SBFD and non-SBFD symbols, and that at least one SBFD symbol is included among the symbols occupied by the PDSCH in multiple slots, it can further determine whether the network device has configured a third frequency domain resource for receiving the PDSCH with SBFD symbols and a fourth frequency domain resource for receiving the PDSCH with non-SBFD symbols. Here, the third frequency domain resource does not include any frequency domain resources other than the downlink resource corresponding to the SBFD symbol.

[0137] If a network device decides to configure a third frequency domain resource for receiving PDSCH with SBFD symbols and a fourth frequency domain resource for receiving PDSCH with non-SBFD symbols, the third frequency domain resource does not conflict with other frequency domain resources because it does not include any other frequency domain resources besides the downlink resource corresponding to the SBFD symbol. Therefore, a PDSCH transmitted across multiple slots can be received in the third frequency domain resource in the SBFD symbols occupied by the PDSCH in the multiple slots used for PDSCH transmission. Correspondingly, the network device can transmit a PDSCH transmitted across multiple slots to a terminal in the third frequency domain resource in the SBFD symbols occupied by the PDSCH in the multiple slots used for PDSCH transmission.

[0138] However, since non-SBFD symbols do not have frequency domain resources other than downlink resources, the fourth frequency domain resource does not conflict with frequency domain resources other than downlink resources. Therefore, a PDSCH transmitted in multiple slots can be received in the fourth frequency domain resource in the non-SBFD symbols occupied by the PDSCH in the multiple slots used for PDSCH transmission. Correspondingly, a network device can transmit a PDSCH transmitted in multiple slots to a terminal in the fourth frequency domain resource in the non-SBFD symbols occupied by the PDSCH in the multiple slots used for PDSCH transmission.

[0139] Figure 11 is a schematic flowchart of another reception determination method according to an embodiment of the present disclosure. The reception determination method according to this embodiment can be performed by a terminal. As shown in Figure 11, the reception determination method further includes the following steps.

[0140] In step S1101, if it is determined that a PDSCH transmitted in multiple slots can be received with SBFD symbols and non-SBFD symbols, and if the symbols on which the PDSCH is located in the first of the multiple slots include non-SBFD symbols, then if the downlink resource corresponding to the non-SBFD symbols is greater than or equal to the first frequency domain resource set up for the PDSCH, a fifth frequency domain resource with a bandwidth equal to that of the first frequency domain resource is determined from the downlink resources, and the PDSCH is received in the first slot using the fifth frequency domain resource. And / or, if the downlink resource corresponding to the non-SBFD symbols is smaller than the first frequency domain resource set up for the PDSCH, the PDSCH is not received in the first slot.

[0141] It should be noted that the embodiment shown in Figure 11 can be implemented independently or in combination with at least one other embodiment of the present disclosure. Specific choices can be made as needed and are not limited by the present disclosure.

[0142] In one embodiment, the terminal can determine that a PDSCH transmitted in multiple slots can be received with SBFD symbols and non-SBFD symbols, and if the symbols in which the PDSCH is located in the first of the multiple slots include non-SBFD symbols, it can further determine the relationship between the downlink resource corresponding to the non-SBFD symbol and the first frequency domain resource set up for the PDSCH.

[0143] If the downlink resource corresponding to a non-SBFD symbol is larger than or equal to the first frequency domain resource configured for the PDSCH, the downlink resource corresponding to the non-SBFD symbol can determine a frequency domain resource (e.g., a fifth frequency domain resource) with a bandwidth equal to that of the first frequency domain resource, and then the PDSCH can be received in the first slot using the fifth frequency domain resource. Since the fifth frequency domain resource has the same bandwidth as the first frequency domain resource, smooth reception of the PDSCH can be guaranteed. Accordingly, the network device can transmit PDSCHs transmitted across multiple slots to the terminal using the fifth frequency domain resource in the first slot.

[0144] In one embodiment, the bandwidth of a first frequency domain resource can be determined first, and this bandwidth can be represented by the number of resource blocks (RBs), for example, k1 RBs.

[0145] For example, starting with the starting RB of the activation bandwidth part (BWP) corresponding to the first slot, k1 consecutive RBs within the activation BWP can be determined. If there are only k1-n RBs between the starting RB of the activation BWP and the first boundary of a resource other than the downlink resource (a boundary relatively close to the starting RB), then n more RBs can be determined within the downlink resource starting from the second boundary of the resource other than the downlink resource (a boundary relatively far from the starting RB), and the determined k1-n RBs and n RBs can be used as a fifth frequency domain range.

[0146] For example, using the end RB of the activated BWP corresponding to the first slot as the endpoint, k1 consecutive RBs within the activated BWP can be determined. If there are only k1-n RBs between the end RB of the activated BWP and the second boundary of a resource other than the downlink resource (a boundary relatively close to the end RB), then n more RBs can be determined within the downlink resource starting from the first boundary of the resource other than the downlink resource (a boundary relatively far from the end RB), and the determined k1-n RBs and n RBs can be used as a fifth frequency domain range.

[0147] For example, in an activated BWP, a frequency domain range having a duration of k2 consecutive RBs can be determined as a sixth frequency domain resource, and a fifth frequency domain range can be determined where the sixth frequency domain resource and the downlink resource corresponding to a non-SBFD symbol overlap, with k1 RBs.

[0148] If the downlink resource corresponding to a non-SBFD symbol is smaller than the first frequency domain resource configured for the PDSCH, a frequency domain resource equal to the bandwidth of the first frequency domain resource may not be determined for the downlink resource corresponding to the non-SBFD symbol, and the terminal will not receive the PDSCH in the first slot. In response to this, the network device does not need to send a PDSCH transmitted across multiple slots to the terminal in the first slot.

[0149] Figure 12 is a schematic flowchart of another reception determination method according to an embodiment of the present disclosure. The reception determination method according to this embodiment can be performed by a terminal. As shown in Figure 12, the reception determination method further includes the following steps.

[0150] In step S1201, if it is determined that a PDSCH transmitted in multiple slots can be received using only SBFD symbols, and there is an overlapping second frequency domain resource between the first frequency domain resource set for the PDSCH in the first of the multiple slots and the downlink resource corresponding to the SBFD symbol, then if the symbols occupied by the PDSCH in the first slot include non-SBFD symbols, the PDSCH will not be received in the first slot, and / or, if the symbols occupied by the PDSCH in the first slot include SBFD symbols and do not include uplink symbols, the PDSCH will be received using the second frequency domain resource in the first slot, and / or, if the symbols occupied by the PDSCH in the first slot include only SBFD symbols, the PDSCH will be received using the second frequency domain resource in the first slot.

[0151] It should be noted that the embodiments shown in Figure 12 may be carried out independently or in combination with at least one other embodiment of the present disclosure. Specific choices can be made as needed, and the disclosure is not limited thereto.

[0152] In one embodiment, the terminal can determine that a PDSCH transmitted in multiple slots can be received using only SBFD symbols, and that if there is an overlapping second frequency domain resource between a first frequency domain resource set for the PDSCH in a first slot among the multiple slots and a downlink resource corresponding to an SBFD symbol, it can further determine whether the symbols occupied by the PDSCH in the first slot include non-SBFD symbols.

[0153] For example, if the symbols occupied by a PDSCH in the first slot include non-SBFD symbols, then when the PDSCH is received in the first slot, the symbols occupied by the PDSCH will include non-SBFD symbols, thus violating the constraint that PDSCH transmitted in multiple slots can only be received with SBFD symbols. Therefore, the terminal does not need to receive PDSCH transmitted in multiple slots in the first slot. Correspondingly, the network device does not need to send PDSCH transmitted in multiple slots to the terminal in the first slot.

[0154] For example, if the symbols occupied by a PDSCH in the first slot include SBFD symbols and do not include uplink symbols, then when the PDSCH is received in the first slot, the symbols occupied by the PDSCH will include SBFD symbols, thus adhering to the constraint that PDSCHs transmitted in multiple slots can be received using only SBFD symbols. Therefore, the terminal can receive PDSCHs transmitted in multiple slots using the second frequency domain resource in the first slot. Correspondingly, the network device can transmit PDSCHs transmitted in multiple slots using the second frequency domain resource to the terminal in the first slot.

[0155] For example, if the symbols occupied by a PDSCH in the first slot include only SBFD symbols, then when the PDSCH is received in the first slot, the symbols occupied by the PDSCH will include only SBFD symbols, thus adhering to the constraint that PDSCHs transmitted in multiple slots can be received using only SBFD symbols. Therefore, the terminal can receive PDSCHs transmitted in multiple slots using the second frequency domain resource in the first slot. Correspondingly, the network device can transmit PDSCHs transmitted in multiple slots using the second frequency domain resource to the terminal in the first slot.

[0156] Figure 13 is a schematic flowchart of another reception determination method according to an embodiment of the present disclosure. The reception determination method according to this embodiment can be performed by a terminal. As shown in Figure 13, the reception determination method further includes the following steps.

[0157] In step S1301, if it is determined that a PDSCH transmitted in multiple slots can be received with only non-SBFD symbols, then if the symbols occupied by the PDSCH in the first of the multiple slots include SBFD symbols, the PDSCH will not be received in the first slot. And / or, if the symbols occupied by the PDSCH in the first slot include downlink symbols and / or flexible symbols, and do not include uplink symbols, the PDSCH will be received in the first slot. And / or, if the symbols occupied by the PDSCH in the first slot include only downlink symbols and / or flexible symbols, the PDSCH will be received in the first slot.

[0158] It should be noted that the embodiment shown in Figure 13 can be implemented independently or in combination with at least one other embodiment of the present disclosure. Specific implementations can be selected as needed and are not limited by the present disclosure.

[0159] In one embodiment, if the terminal determines that the PDSCH transmitted in multiple slots can be received only as non-SBFD symbols, it can further determine the symbols occupied by the PDSCH in the first slot.

[0160] For example, if the symbols occupied by a PDSCH in the first slot include SBFD symbols, then when a PDSCH is received in the first slot, the symbols occupied by the PDSCH will include SBFD symbols, thus violating the constraint that PDSCHs transmitted in multiple slots can only be received with non-SBFD symbols. Therefore, the terminal does not need to receive PDSCHs transmitted in multiple slots in the first slot. Correspondingly, the network device does not need to send PDSCHs transmitted in multiple slots to the terminal in the first slot.

[0161] For example, if the symbols occupied by a PDSCH in the first slot include downlink symbols and / or flexible symbols, but not uplink symbols, then when the PDSCH is received in the first slot, the symbols occupied by the PDSCH include downlink symbols and / or flexible symbols, but not uplink symbols. Since non-SBFD symbols include downlink symbols, flexible symbols, and uplink symbols, the constraint that a PDSCH transmitted in multiple slots can be received with only non-SBFD symbols can be met. Therefore, a terminal can receive a PDSCH transmitted in multiple slots in the first slot. Correspondingly, a network device can transmit a PDSCH transmitted in multiple slots to a terminal in the first slot.

[0162] For example, if the symbols occupied by a PDSCH in the first slot include only downlink symbols and / or flexible symbols, then when the PDSCH is received in the first slot, the symbols occupied by the PDSCH will also include only downlink symbols and / or flexible symbols. Therefore, PDSCHs transmitted in multiple slots are subject to the constraint that they can only be received with non-SBFD symbols. Consequently, a terminal can receive a PDSCH transmitted in multiple slots in the first slot. Correspondingly, a network device can transmit a PDSCH transmitted in multiple slots to a terminal in the first slot.

[0163] Figure 14 is a schematic flowchart of a receiving instruction method according to an embodiment of the present disclosure. The receiving instruction method shown in this embodiment can be performed by a network device, and the network device can communicate with a terminal. The network device includes, but is not limited to, base stations in a communication system such as 4G base stations, 5G base stations, and 6G base stations. The terminal includes, but is not limited to, mobile phones, tablet computers, wearable devices, sensors, IoT devices, and other communication devices.

[0164] As shown in Figure 14, the receiving instruction method may include the following steps.

[0165] In step S1401, first information is transmitted to the terminal. This first information is used to indicate symbols that the terminal can use to receive PDSCH transmitted in multiple slots, and the symbols include at least one of SBFD symbols and non-SBFD symbols.

[0166] In one embodiment, a network device can transmit first information to a terminal for indicating symbols available for receiving PDSCH transmitted in multiple slots, wherein the symbols include at least one of SBFD symbols and non-SBFD symbols. That is, the first information can indicate that the terminal can receive PDSCH transmitted in multiple slots with SBFD symbols and non-SBFD symbols, or can receive PDSCH transmitted in multiple slots with SBFD symbols only, or can receive PDSCH transmitted in multiple slots with non-SBFD symbols only.

[0167] For example, a network device can determine that it can transmit PDSCH transmitted in multiple slots to a terminal using only SBFD symbols, and through the first information, it can instruct the terminal to receive only PDSCH transmitted in multiple slots using SBFD symbols. Alternatively, a network device can determine that it can transmit PDSCH transmitted in multiple slots to a terminal using only non-SBFD symbols, and through the first information, it can instruct the terminal to receive only PDSCH transmitted in multiple slots using non-SBFD symbols. Alternatively, a network device can determine that it can transmit PDSCH transmitted in multiple slots to a terminal using both SBFD and non-SBFD symbols, and through the first information, it can instruct the terminal to receive PDSCH transmitted in multiple slots using both SBFD and non-SBFD symbols.

[0168] This ensures that the symbols that a terminal determines it can receive PDSCH transmitted through multiple slots match the symbols that a network device determines it can send PDSCH transmitted through multiple slots to the terminal. This results in a consistent understanding between the terminal and the network device, leading to improved communication quality between the network device and the terminal.

[0169] The embodiments of this disclosure are primarily used to illustrate technical solutions when the SBFD symbol is a symbol with an uplink subband configured. However, the technical solutions of this disclosure can also be applied when the SBFD symbol is a symbol with a downlink subband configured.

[0170] In one embodiment, the first information includes at least one of frequency domain resource information and an instruction field.

[0171] In one embodiment, if it is determined that the symbols available for transmitting a PDSCH transmitted across multiple slots to a terminal include SBFD symbols and non-SBFD symbols, the frequency domain resource information sets the frequency domain resource of the PDSCH within the downlink resource corresponding to the SBFD symbol, and / or, if it is determined that the symbols available for transmitting a PDSCH transmitted across multiple slots to a terminal include either SBFD symbols or non-SBFD symbols, the frequency domain resource information sets the frequency domain resource of the PDSCH to include frequency domain resources other than the downlink resource corresponding to the SBFD symbol.

[0172] As shown in Figure 4A, the network device can determine that it can transmit a PDSCH transmitted across multiple slots to the terminal using both SBFD and non-SBFD symbols. Furthermore, the frequency domain resource information transmitted by the network device to the terminal allows the frequency domain resource for the PDSCH transmitted across multiple slots to be set to FD#1, and FD#1 is located within the downlink resource corresponding to the SBFD symbol. If the terminal determines that FD#1 is located within the downlink resource corresponding to the SBFD symbol, it can then determine that it can receive the PDSCH transmitted across multiple slots using both SBFD and non-SBFD symbols. For example, it can determine that it can receive the PDSCH transmitted across multiple slots from symbol #3 to symbol #8. In response, the network device transmits the PDSCH transmitted across multiple slots from symbol #3 to symbol #8 to the terminal.

[0173] As shown in Figure 4B, the network device can determine that it can transmit a PDSCH transmitted across multiple slots to the terminal using non-SBFD symbols. Furthermore, the frequency domain resource information transmitted by the network device to the terminal allows the frequency domain resource for the PDSCH transmitted across multiple slots to be set to FD#1, and FD#1 includes frequency domain resources other than the downlink resource corresponding to the SBFD symbol. If the terminal determines that FD#1 contains frequency domain resources other than the downlink resource corresponding to the SBFD symbol (for example, if there is a resource collision between FD#1 and the frequency domain resource other than the downlink resource in Figure 4B), it can further determine that the PDSCH transmitted across multiple slots can only be received using either SBFD symbols or non-SBFD symbols. For example, it can determine that the PDSCH transmitted across multiple slots can only be received using non-SBFD symbols (symbols #3 to #5). In response, the network device transmits the PDSCH transmitted across multiple slots to the terminal using symbols #3 to #5.

[0174] Furthermore, if a network device determines that PDSCH transmitted across multiple slots can be sent to the terminal using only SBFD symbols, the frequency domain resource information can be configured to include frequency domain resources other than the downlink resource where FD#1 corresponds to the SBFD symbol. However, in this case, the terminal can only determine that PDSCH transmitted across multiple slots can be received using only SBFD symbols if the symbol on which the first PDSCH among the PDSCH transmitted across multiple slots is located contains an SBFD symbol, or if all the symbols on which the first PDSCH among the PDSCH transmitted across multiple slots is located are SBFD symbols.

[0175] In one embodiment, the step of determining whether PDSCH transmitted in multiple slots can be sent to the terminal using only SBFD symbols or non-SBFD symbols is: The steps include determining that if the symbol on which the first PDSCH among the PDSCHs transmitted in multiple slots is located includes an SBFD symbol, the PDSCHs transmitted in multiple slots can be sent to the terminal using only SBFD symbols, and If all symbols on which the first PDSCH is located in a PDSCH transmitted through multiple slots are non-SBFD symbols, the step of determining that the PDSCH transmitted through multiple slots can be sent to the terminal using only non-SBFD symbols, It includes at least one of the following.

[0176] For example, a network device can determine which slot contains the first PDSCH among multiple PDSCHs being transmitted in those slots, and then determine the symbol in which the first PDSCH is located in that slot. If the symbol in which the first PDSCH is located in that slot contains an SBFD symbol, the network device can determine that the PDSCH transmitted in multiple slots can be sent to the terminal using only SBFD symbols. Also, if all the symbols in which the first PDSCH is located in that slot are non-SBFD symbols, the network device can determine that the PDSCH transmitted in multiple slots can be sent to the terminal using only non-SBFD symbols.

[0177] In one embodiment, the step of determining whether PDSCH transmitted in multiple slots can be sent to the terminal using only SBFD symbols or non-SBFD symbols is: If all symbols on which the first PDSCH is located among PDSCHs transmitted in multiple slots are SBFD symbols, the step of determining that the PDSCHs transmitted in multiple slots can be sent to the terminal using only SBFD symbols, and If the symbol on which the first PDSCH among those transmitted in multiple slots is located contains a non-SBFD symbol, the step of determining that the PDSCH transmitted in multiple slots can be sent to the terminal using only non-SBFD symbols, It includes at least one of the following.

[0178] For example, a network device can determine which slot contains the first PDSCH among multiple PDSCHs being transmitted, and determine the symbols in that slot where the first PDSCH is located. If all the symbols in that slot where the first PDSCH is located are SBFD symbols, the network device can determine that the PDSCH transmitted across multiple slots can be sent to the terminal using only SBFD symbols. If the symbols in that slot where the first PDSCH is located include non-SBFD symbols, the network device can determine that the PDSCH transmitted across multiple slots can be sent to the terminal using only non-SBFD symbols.

[0179] In one embodiment, if it is determined that the symbols available for sending a PDSCH transmitted across multiple slots to a terminal include SBFD symbols and non-SBFD symbols, and the frequency domain resource information is configured such that the frequency domain resources of the PDSCH include frequency domain resources for receiving the PDSCH with SBFD symbols and frequency domain resources for receiving the PDSCH with non-SBFD symbols, then it is determined that the PDSCH transmitted across multiple slots can be transmitted with SBFD symbols and non-SBFD symbols.

[0180] In one embodiment, if a network device determines that the symbols available for sending PDSCH transmitted across multiple slots to a 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 is configured to set up frequency domain resources for receiving PDSCH with SBFD symbols and frequency domain resources for receiving PDSCH with non-SBFD symbols, and the frequency domain resources for receiving PDSCH with SBFD symbols do not include frequency domain resources other than the downlink resources corresponding to the SBFD symbols.

[0181] In this case, the network device can transmit PDSCH transmitted across multiple slots to the terminal using both SBFD and non-SBFD symbols. The terminal can determine, based on frequency domain resource information, that it can receive PDSCH transmitted across multiple slots using both SBFD and non-SBFD symbols.

[0182] For example, in the case of a non-SBFD symbol, the PDSCH may be transmitted to the terminal using frequency-domain resources for receiving PDSCH in a non-SBFD symbol, and in the case of an SBFD symbol, the PDSCH may be transmitted to the terminal using frequency-domain resources for receiving PDSCH in an SBFD symbol.

[0183] In one embodiment, the instruction field occupies one or two bits. It should be noted that the number of bits occupied by the instruction field is not limited to one or two, but may be any other number. The following embodiments will primarily illustrate the technical solutions of this disclosure using the cases where the instruction field occupies one bit and the case where the instruction field occupies two bits as examples.

[0184] In one embodiment, if it is determined that the symbols available for transmitting a PDSCH transmitted in multiple slots to a terminal include SBFD symbols and non-SBFD symbols, the instruction field indicates that the terminal can receive the PDSCH transmitted in multiple slots with SBFD symbols and non-SBFD symbols, and / or, if it is determined that the symbols available for transmitting a PDSCH transmitted in multiple slots to a terminal include SBFD symbols or non-SBFD symbols, the instruction field indicates that the terminal can receive the PDSCH transmitted in multiple slots with SBFD symbols or non-SBFD symbols only.

[0185] In one embodiment, if the instruction field occupies 1 bit, the instruction field can instruct the terminal that PDSCH transmitted in multiple slots can be received with SBFD symbols and non-SBFD symbols, or that PDSCH transmitted in multiple slots can be received with either SBFD symbols or non-SBFD symbols only.

[0186] For example, if a network device determines that the symbols it can use to send a PDSCH transmitted across multiple slots to a terminal include both SBFD and non-SBFD symbols, the value of the 1-bit instruction field sent to the terminal is 1, indicating that the terminal can receive the PDSCH transmitted across multiple slots with both SBFD and non-SBFD symbols.

[0187] For example, if a network device determines that the symbols it can use to send a PDSCH transmitted across multiple slots to a terminal include SBFD symbols or non-SBFD symbols, the value of the 1-bit instruction field sent to the terminal is 0, indicating that the terminal can only receive PDSCH transmitted across multiple slots as SBFD symbols or non-SBFD symbols.

[0188] In one embodiment, the step of determining whether PDSCH transmitted in multiple slots can be sent to the terminal using only SBFD symbols or non-SBFD symbols is: If the symbol on which the first PDSCH among the PDSCHs transmitted in multiple slots is located contains an SBFD symbol, the step of determining that the PDSCHs transmitted in multiple slots can be sent to the terminal using only SBFD symbols, and If all symbols on which the first PDSCH is located in a PDSCH transmitted through multiple slots are non-SBFD symbols, the step of determining that the PDSCH transmitted through multiple slots can be sent to the terminal using only non-SBFD symbols, It includes at least one of the following.

[0189] For example, a network device can determine which slot contains the first PDSCH among multiple PDSCHs being transmitted, and determine the symbol in which the first PDSCH is located within that slot. If the symbol in which the first PDSCH is located within that slot contains an SBFD symbol, the network device can determine that the PDSCH transmitted across multiple slots can be sent to the terminal using only SBFD symbols. Furthermore, if all the symbols in which the first PDSCH is located within that slot are non-SBFD symbols, the network device can determine that the PDSCH transmitted across multiple slots can be sent to the terminal using only non-SBFD symbols.

[0190] In one embodiment, the step of determining whether PDSCH transmitted in multiple slots can be sent to the terminal using only SBFD symbols or non-SBFD symbols is: If all symbols on which the first PDSCH is located among PDSCHs transmitted in multiple slots are SBFD symbols, the step of determining that the PDSCHs transmitted in multiple slots can be sent to the terminal using only SBFD symbols, and If the symbol on which the first PDSCH among those transmitted in multiple slots is located contains a non-SBFD symbol, the step of determining that the PDSCH transmitted in multiple slots can be sent to the terminal using only non-SBFD symbols, It includes at least one of the following.

[0191] For example, a network device can determine which slot contains the first PDSCH among multiple PDSCHs being transmitted, and determine the symbols in that slot where the first PDSCH is located. If all the symbols in that slot where the first PDSCH is located are SBFD symbols, the network device can determine that the PDSCH transmitted across multiple slots can be sent to the terminal using only SBFD symbols. If the symbols in that slot where the first PDSCH is located include non-SBFD symbols, the network device can determine that the PDSCH transmitted across multiple slots can be sent to the terminal using only non-SBFD symbols.

[0192] In one embodiment, the step of determining whether PDSCH transmitted in multiple slots can be sent to the terminal using only SBFD symbols or non-SBFD symbols is: If all symbols on which the first PDSCH is located among PDSCHs transmitted in multiple slots are SBFD symbols, the step of determining that the PDSCHs transmitted in multiple slots can be sent to the terminal using only SBFD symbols, and If all symbols on which the first PDSCH is located in a PDSCH transmitted through multiple slots are non-SBFD symbols, the step of determining that the PDSCH transmitted through multiple slots can be sent to the terminal using only non-SBFD symbols, It includes at least one of the following.

[0193] For example, a network device can determine which slot contains the first PDSCH among multiple PDSCHs being transmitted, and determine the symbols in that slot where the first PDSCH is located. If all the symbols in that slot where the first PDSCH is located are SBFD symbols, the network device can determine that the PDSCH transmitted across multiple slots can be sent to the terminal using only SBFD symbols. If all the symbols in that slot where the first PDSCH is located are non-SBFD symbols, the network device can determine that the PDSCH transmitted across multiple slots can be sent to the terminal using only non-SBFD symbols.

[0194] In one embodiment, the step of determining the symbols available for transmitting PDSCH to be transmitted in multiple slots is: If it is determined that the only symbols available to send a PDSCH transmitted across multiple slots to the terminal are SBFD symbols, then the terminal is instructed to receive the PDSCH transmitted across multiple slots as SBFD symbols only (the instruction field is the first value, the second value, or the instruction field is empty). If it is determined that the symbols available to send a PDSCH transmitted across multiple slots to the terminal consist only of non-SBFD symbols, the terminal is instructed to receive the PDSCH transmitted across multiple slots as only non-SBFD symbols (the instruction field is the first value, the second value, or the instruction field is empty), and If it is determined that a PDSCH transmitted across multiple slots can be transmitted with both SBFD and non-SBFD symbols, the terminal is instructed to receive the PDSCH transmitted across multiple slots with both SBFD and non-SBFD symbols (the instruction field is either a first value, a second value, or empty). It includes at least one of the following.

[0195] It is understood that the content indicated by the first information differs depending on whether the indicator field has a first value, a second value, or is empty. The following describes, through several embodiments, what the content indicated by the first information is when the indicator field has a first value, a second value, or is empty, but the correspondence between what the content indicated by the first information and whether the indicator field has a first value, a second value, or is empty is not limited to the following embodiments.

[0196] In one embodiment, if the instruction field occupies 1 bit, the instruction field can instruct the terminal that PDSCH transmitted in multiple slots can be received only as SBFD symbols, or that PDSCH transmitted in multiple slots can be received only as non-SBFD symbols. If the instruction field is empty, it can instruct the terminal that PDSCH transmitted in multiple slots can be received as both SBFD and non-SBFD symbols.

[0197] For example, a network device determines that it can send a PDSCH transmitted through multiple slots to a terminal using only SBFD symbols, and the value of the instruction field, which occupies 1 bit, sent to the terminal is 1, instructing the terminal that it can receive the PDSCH transmitted through multiple slots using only SBFD symbols.

[0198] For example, a network device may decide that it can send a PDSCH transmitted across multiple slots to a terminal using only non-SBFD symbols, and the value of the instruction field, which occupies one bit, sent to the terminal is 0, instructing the terminal that it can receive the PDSCH transmitted across multiple slots using only non-SBFD symbols.

[0199] For example, if a network device determines that it can send a PDSCH transmitted through multiple slots to a terminal with both SBFD and non-SBFD symbols, the network device sets the instruction field to empty, instructing the terminal that it can receive the PDSCH transmitted through multiple slots with both SBFD and non-SBFD symbols.

[0200] In one embodiment, if the instruction field occupies 1 bit, the instruction field can instruct the terminal that PDSCH transmitted in multiple slots can be received only as SBFD symbols, or that PDSCH transmitted in multiple slots can be received as both SBFD and non-SBFD symbols. If the instruction field is empty, the instruction field can instruct the terminal that PDSCH transmitted in multiple slots can be received only as non-SBFD symbols.

[0201] For example, a network device determines that it can send a PDSCH transmitted through multiple slots to a terminal using only SBFD symbols, and the value of the instruction field, which occupies 1 bit, sent to the terminal is 1, instructing the terminal that it can receive the PDSCH transmitted through multiple slots using only SBFD symbols.

[0202] For example, a network device determines that it can send a PDSCH transmitted through multiple slots to a terminal in both SBFD and non-SBFD symbols, and the value of the instruction field, which occupies one bit, sent to the terminal is 0, instructing the terminal that it can receive the PDSCH transmitted through multiple slots in both SBFD and non-SBFD symbols.

[0203] For example, if a network device determines that it can send PDSCH transmitted through multiple slots to a terminal using only non-SBFD symbols, the network device sets the instruction field to empty, instructing the terminal that PDSCH transmitted through multiple slots can be received using only non-SBFD symbols.

[0204] In one embodiment, if the instruction field occupies 1 bit, the instruction field can instruct the terminal that PDSCH transmitted in multiple slots can be received with both SBFD and non-SBFD symbols, or that PDSCH transmitted in multiple slots can be received with only non-SBFD symbols. If the instruction field is empty, the instruction field can instruct the terminal that PDSCH transmitted in multiple slots can be received with only SBFD symbols.

[0205] For example, a network device determines that it can send a PDSCH transmitted through multiple slots to a terminal in both SBFD and non-SBFD symbols, and the value of the instruction field, which occupies one bit, sent to the terminal is 1, instructing the terminal that it can receive the PDSCH transmitted through multiple slots in both SBFD and non-SBFD symbols.

[0206] For example, a network device may decide that it can send a PDSCH transmitted across multiple slots to a terminal using only non-SBFD symbols, and the value of the instruction field, which occupies 1 bit, sent to the terminal is , instructing the terminal that it can receive a PDSCH transmitted across multiple slots using only non-SBFD symbols.

[0207] For example, a network device may decide that it can send PDSCH transmitted through multiple slots to a terminal using only SBFD symbols, and the network device may set the instruction field to empty, instructing the terminal that PDSCH transmitted through multiple slots can be received using only SBFD symbols.

[0208] In one embodiment, if it is determined that the symbols available for sending a PDSCH transmitted in multiple slots to a terminal include SBFD symbols and non-SBFD symbols, the instruction field indicates that the terminal can receive the PDSCH transmitted in multiple slots with SBFD symbols and non-SBFD symbols, and / or if it is determined that the symbols available for sending a PDSCH transmitted in multiple slots to a terminal include only SBFD symbols, the instruction field indicates that the terminal can receive the PDSCH transmitted in multiple slots with SBFD symbols only, and / or if it is determined that the symbols available for sending a PDSCH transmitted in multiple slots to a terminal include only non-SBFD symbols, the instruction field indicates that the terminal can receive the PDSCH transmitted in multiple slots with non-SBFD symbols only.

[0209] In one embodiment, if the instruction field occupies 2 bits, the instruction field can instruct the terminal that PDSCH transmitted in multiple slots can be received with both SBFD and non-SBFD symbols, or that PDSCH transmitted in multiple slots can be received only with non-SBFD symbols, or that PDSCH transmitted in multiple slots can be received only with SBFD symbols.

[0210] For example, a network device determines that it can send a PDSCH transmitted through multiple slots to a terminal in both SBFD and non-SBFD symbols, and the value of the 2-bit instruction field sent to the terminal is 00, instructing the terminal that it can receive the PDSCH transmitted through multiple slots in both SBFD and non-SBFD symbols.

[0211] For example, a network device determines that it can send PDSCH transmitted through multiple slots to a terminal using only SBFD symbols, and the value of the 2-bit instruction field sent to the terminal is 01, instructing the terminal that PDSCH transmitted through multiple slots can be received using only SBFD symbols.

[0212] For example, a network device may decide that it can send PDSCH transmitted through multiple slots to a terminal using only non-SBFD symbols, and the value of the 2-bit instruction field sent to the terminal is 10, instructing the terminal that PDSCH transmitted through multiple slots can be received using only non-SBFD symbols.

[0213] In the embodiments of this disclosure, the statement that a PDSCH transmitted in multiple slots using a certain type of symbol can be sent to a terminal does not mean that the network device must transmit a PDSCH transmitted in multiple slots using this type of symbol to the terminal. Rather, it means that the network device can transmit a PDSCH transmitted in multiple slots using this type of symbol to the terminal, but cannot transmit a PDSCH transmitted in multiple slots using symbols other than this type of symbol to the terminal.

[0214] For example, when a network device determines that it can transmit a PDSCH transmitted across multiple slots to a terminal using both SBFD and non-SBFD symbols, it does not mean that the network device must transmit the PDSCH transmitted across multiple slots to the terminal using both SBFD and non-SBFD symbols in each slot where the PDSCH is located. Rather, it means that the network device is capable of transmitting the PDSCH transmitted across multiple slots to the terminal using both SBFD and non-SBFD symbols in each slot where the PDSCH is located.

[0215] For example, when a network device determines that it can send a PDSCH transmitted across multiple slots to a terminal using only SBFD symbols, it does not mean that the network device must send the PDSCH transmitted across multiple slots to the terminal using SBFD symbols in each slot where the PDSCH is located. Rather, it means that the network device can send the PDSCH transmitted across multiple slots to the terminal using SBFD symbols in each slot where the PDSCH is located, but cannot receive the PDSCH transmitted across multiple slots using non-SBFD symbols.

[0216] For example, when a network device determines that it can send a PDSCH transmitted across multiple slots to a terminal using only non-SBFD symbols, it does not mean that the network device must send the PDSCH transmitted across multiple slots to the terminal using only non-SBFD symbols in each slot where the PDSCH is located. Rather, it means that the network device can send the PDSCH transmitted across multiple slots to the terminal using only non-SBFD symbols in each slot where the PDSCH is located, but cannot receive the PDSCH transmitted across multiple slots using SBFD symbols.

[0217] The network device needs to further determine which symbol within each slot where the PDSCH is located will be used to transmit the PDSCH across multiple slots to the terminal. Specific methods for making these determinations will be described in the later examples.

[0218] In one embodiment, the receiving instruction method further includes the step of transmitting a PDSCH in a first frequency domain resource set up for a PDSCH in a plurality of slots if it is determined that a PDSCH transmitted in a plurality of slots can be transmitted with SBFD symbols and non-SBFD symbols, and the symbols occupied by the PDSCH in the plurality of slots do not include SBFD symbols.

[0219] If a network device determines that a PDSCH transmitted across multiple slots can transmit with both SBFD and non-SBFD symbols, it can further determine whether the symbols occupied by the PDSCH across those multiple slots include SBFD symbols.

[0220] If the symbols occupied by the PDSCH in multiple slots do not include SBFD symbols, when a network device transmits the PDSCH across multiple slots, the PDSCH will not be received by SBFD symbols. Therefore, the first resource FD#1 configured for the PDSCH in multiple slots will not conflict with frequency domain resources other than downlink resources, and thus the PDSCH can be transmitted using FD#1 in multiple slots.

[0221] In one embodiment, the receiving instruction method further includes the step of transmitting a PDSCH in a first slot if it is determined that a PDSCH transmitted in a plurality of slots can be transmitted with SBFD symbols and non-SBFD symbols, and a first frequency domain resource configured for the PDSCH in a first slot of the plurality of slots is located within the downlink resources corresponding to SBFD symbols.

[0222] If a network device determines that a PDSCH transmitted across multiple slots can be received with both SBFD and non-SBFD symbols, it can further determine whether a first frequency domain resource FD#1 configured for the PDSCH in a first of the multiple slots includes frequency domain resources other than downlink resources corresponding to SBFD symbols.

[0223] If FD#1 includes frequency domain resources other than the downlink resource corresponding to the SBFD symbol, i.e., if FD#1 is not located within the downlink resource corresponding to the SBFD symbol, when a network device receives a PDSCH transmitted in multiple slots with the SBFD symbol in the first slot, FD#1 will collide with frequency domain resources other than the downlink resource, and therefore does not need to send the PDSCH transmitted in multiple slots to the terminal in the first slot.

[0224] If FD#1 does not contain any frequency domain resources other than the downlink resource corresponding to the SBFD symbol, that is, if FD#1 is located within the downlink resource corresponding to the SBFD symbol, then when a network device receives a PDSCH transmitted in multiple slots with the SBFD symbol in the first slot, FD#1 will not conflict with any frequency domain resources other than the downlink resource, and therefore the PDSCH transmitted in multiple slots can be sent to the terminal in the first slot.

[0225] In one embodiment, the receiving instruction method further includes the step of not transmitting the PDSCH in the first slot if it is determined that the PDSCH transmitted in multiple slots can be transmitted with SBFD symbols and non-SBFD symbols, and the symbols occupied by the PDSCH in the first slot of the multiple slots include at least one SBFD symbol, and the first frequency domain resource set up for the PDSCH in the first slot includes frequency domain resources other than downlink resources corresponding to SBFD symbols.

[0226] In one embodiment, the receiving instruction method further includes the step of not transmitting a PDSCH in a first slot if the symbols occupied by the PDSCH in the first slot of a plurality of slots include an uplink symbol. This embodiment can be combined with other embodiments of the present disclosure.

[0227] Regardless of whether the network device decides that it can transmit a PDSCH transmitted across multiple slots to the terminal with both SBFD and non-SBFD symbols, or that it can transmit a PDSCH transmitted across multiple slots to the terminal with only SBFD symbols, or that it can transmit a PDSCH transmitted across multiple slots to the terminal with only non-SBFD symbols, it can decide whether the symbols occupied by the PDSCH in the first slot of the multiple slots used to receive the PDSCH (for example, a flexible slot configured with an uplink subband) include uplink symbols. If it is determined that the symbols occupied by the PDSCH in the first slot include uplink symbols, then the PDSCH does not need to be transmitted to the terminal in the first slot because FD#1 would conflict with frequency domain resources other than downlink resources.

[0228] In one embodiment, the receiving instruction method further includes the step of transmitting the PDSCH in multiple slots using the second frequency domain resource if it is determined that the PDSCH transmitted in multiple slots can be transmitted using both SBFD and non-SBFD symbols, and the symbols occupied by the PDSCH in multiple slots include at least one SBFD symbol, and there is an overlapping second frequency domain resource between the first frequency domain resource set for the PDSCH in multiple slots and the downlink resource corresponding to the SBFD symbol.

[0229] In one embodiment, if a network device determines that it can transmit PDSCH transmitted across multiple slots to a terminal using both SBFD and non-SBFD symbols, it can further determine whether there is a second frequency domain resource FD#2 that overlaps between a first frequency domain resource FD#1 configured for PDSCH across multiple slots and the downlink resource corresponding to the SBFD symbol.

[0230] If a second frequency domain resource, FD#2, exists that overlaps between FD#1 and the downlink resource corresponding to the SBFD symbol, the network device can send the PDSCH transmitted in multiple slots via FD#2 to the terminal in multiple slots for receiving the PDSCH.

[0231] Since FD#2 is located within the downlink resource corresponding to the SBFD symbol, sending PDSCH transmitted across multiple slots to the terminal via FD#2 ensures that the frequency domain resources for receiving PDSCH with the SBFD symbol in each slot do not conflict with frequency domain resources other than the downlink resource.

[0232] In one embodiment, the network device can determine whether there is a second frequency domain resource FD#2 that overlaps between a first frequency domain resource FD#1 configured for a PDSCH in a first slot of multiple slots and the downlink resource corresponding to an SBFD symbol, and then determine whether at least one SBFD symbol is included in the symbols occupied by the first PDSCH among the PDSCHs transmitted in multiple slots.

[0233] If there is a second frequency domain resource FD#2 that overlaps between FD#1 and the downlink resource corresponding to the SBFD symbol, and the symbols occupied by the first PDSCH among the PDSCHs transmitted in multiple slots include at least one SBFD symbol, then the network device can transmit the PDSCH transmitted in multiple slots via FD#2 to the terminal in multiple slots for transmitting the PDSCH to the terminal.

[0234] In one embodiment, the network device can determine whether there is a second frequency domain resource FD#2 that overlaps between a first frequency domain resource FD#1 configured for a PDSCH in a first slot of multiple slots and the downlink resource corresponding to the SBFD symbol, and then determine whether at least one SBFD symbol is included in the symbols occupied by all PDSCHs transmitted in the multiple slots.

[0235] If there is a second frequency domain resource FD#2 that overlaps between FD#1 and the downlink resource corresponding to the SBFD symbol, and if at least one SBFD symbol is included in the symbols occupied by all PDSCHs among the PDSCHs transmitted in multiple slots, then the network device can transmit the PDSCH transmitted in multiple slots via FD#2 to the terminal in multiple slots for transmitting the PDSCH to the terminal.

[0236] In one embodiment, the receiving instruction method further includes the step of transmitting the PDSCH using the second frequency domain resource for the SBFD symbol in the first slot of the multiple slots, and transmitting the PDSCH using the first frequency domain resource for the non-SBFD symbol in the first slot of the multiple slots, provided that it is determined that the PDSCH transmitted in multiple slots can be transmitted using both SBFD symbols and non-SBFD symbols, and the symbols occupied by the PDSCH in multiple slots include at least one SBFD symbol, and there exists an overlapping second frequency domain resource between a first frequency domain resource set up for the PDSCH and a downlink resource corresponding to an SBFD symbol in multiple slots.

[0237] In one embodiment, if a network device determines that it can transmit PDSCH transmitted across multiple slots to a terminal using both SBFD and non-SBFD symbols, it can further determine whether there is a second frequency domain resource FD#2 that overlaps between a first frequency domain resource FD#1 configured for PDSCH in a first slot among the multiple slots and the downlink resource corresponding to the SBFD symbol.

[0238] If there is a second frequency domain resource FD#2 that overlaps between FD#1 and the downlink resource corresponding to the SBFD symbol, the network device can send a PDSCH transmitted in multiple slots via FD#2 to the terminal in the SBFD symbol of the first slot, and a PDSCH transmitted in multiple slots via FD#1 to the terminal in the non-SBFD symbol of the first slot.

[0239] Since FD#2 is located within the downlink resource corresponding to the SBFD symbol, sending PDSCH transmitted across multiple slots to the terminal via FD#2 in the SBFD symbol ensures that the frequency domain resources used to send PDSCH to the terminal in each slot of the SBFD symbol do not conflict with frequency domain resources other than the downlink resource. However, since non-SBFD symbols do not have frequency domain resources other than the downlink resource, PDSCH transmitted across multiple slots can be sent to the terminal via FD#1 in the non-SBFD symbol, ensuring that it does not conflict with frequency domain resources other than the downlink resource and that the frequency domain resources are fully utilized.

[0240] In one embodiment, the receiving instruction method further includes the steps of transmitting a PDSCH on a first frequency domain resource configured for a PDSCH in the first slot if it is determined that a PDSCH transmitted in multiple slots can be transmitted with SBFD symbols and non-SBFD symbols, and the symbols occupied by the PDSCH in the multiple slots include at least one SBFD symbol, and the symbols occupied by the PDSCH in the first slot of the multiple slots do not include an SBFD symbol, and / or if the symbols occupied by the PDSCH in the first slot of the multiple slots include an SBFD symbol, then transmitting a PDSCH on a second frequency domain resource that overlaps between the first frequency domain resource configured for a PDSCH in the first slot and the downlink resource corresponding to the SBFD symbol.

[0241] In one embodiment, the network device can determine that a PDSCH transmitted in multiple slots can transmit with SBFD symbols and non-SBFD symbols, and that the symbols occupied by the PDSCH in multiple slots include at least one SBFD symbol, and can further determine whether the symbols occupied by the PDSCH in a first slot among the multiple slots include an SBFD symbol.

[0242] For example, if it is determined that the symbols occupied by the PDSCH in the first slot do not include SBFD symbols, the first frequency domain resource configured for the PDSCH in the first slot will not conflict with any frequency domain resources other than downlink resources. Therefore, the network device can transmit the PDSCH to the terminal using the first frequency domain resource configured for the PDSCH in the first slot.

[0243] For example, if the network device determines that the symbols occupied by the PDSCH in the first slot include SBFD symbols, it can further determine a second frequency domain resource that overlaps between the first frequency domain resource configured for the PDSCH in the first slot and the downlink resource corresponding to the SBFD symbols. Since the second frequency domain resource lies within the downlink resource corresponding to the SBFD symbols and does not conflict with any other frequency domain resources, the network device can transmit the PDSCH to the terminal using the second frequency domain resource in the first slot.

[0244] In one embodiment, the receiving instruction method further includes the step of transmitting the PDSCH using the third frequency domain resource for SBFD symbols and the PDSCH using the fourth frequency domain resource for non-SBFD symbols, if it is determined that a PDSCH transmitted in multiple slots can be transmitted using both SBFD and non-SBFD symbols, and a third frequency domain resource for receiving the PDSCH using SBFD symbols and a fourth frequency domain resource for receiving the PDSCH using non-SBFD symbols are configured.

[0245] In one embodiment, if a network device determines that a PDSCH transmitted across multiple slots can be sent to a terminal using both SBFD and non-SBFD symbols, and that the symbols occupied by the PDSCH across multiple slots include at least one SBFD symbol, the network device can further determine whether it has configured a third frequency domain resource for receiving the PDSCH using SBFD symbols and a fourth frequency domain resource for receiving the PDSCH using non-SBFD symbols. Here, the third frequency domain resource does not include any frequency domain resources other than the downlink resource corresponding to the SBFD symbol.

[0246] If a network device configures a terminal to receive a PDSCH using SBFD symbols and a fourth frequency domain resource to receive a PDSCH using non-SBFD symbols, the third frequency domain resource does not include any frequency domain resources other than the downlink resource corresponding to the SBFD symbols, and therefore does not conflict with any frequency domain resources other than the downlink resource. Consequently, for SBFD symbols occupied by PDSCHs in multiple slots used for PDSCH transmission, the third frequency domain resource can transmit PDSCHs transmitted in multiple slots to the terminal.

[0247] However, since non-SBFD symbols do not have frequency domain resources other than downlink resources, the fourth frequency domain resource does not conflict with frequency domain resources other than downlink resources. Therefore, in non-SBFD symbols occupied by PDSCH in multiple slots used for PDSCH transmission, the PDSCH can be transmitted to the terminal using the fourth frequency domain resource.

[0248] In one embodiment, the receiving instruction method further includes the steps of determining a fifth frequency domain resource from the downlink resources whose bandwidth is equal to that of the first frequency domain resource, if it is determined that a PDSCH transmitted in multiple slots can be transmitted with SBFD symbols and non-SBFD symbols, and if the symbols in which the PDSCH is located in the first of the multiple slots include non-SBFD symbols, then transmitting the PDSCH in the first slot using the fifth frequency domain resource if the downlink resource corresponding to the non-SBFD symbols is greater than or equal to the first frequency domain resource set up for the PDSCH, and / or not transmitting the PDSCH in the first slot if the downlink resource corresponding to the non-SBFD symbols is smaller than the first frequency domain resource set up for the PDSCH.

[0249] In one embodiment, the network device determines that a PDSCH transmitted in multiple slots can be sent to a terminal with SBFD symbols and non-SBFD symbols, and if the symbols in which the PDSCH is located in the first of the multiple slots include non-SBFD symbols, it can further determine the relationship between the downlink resource corresponding to the non-SBFD symbol and the first frequency domain resource configured for the PDSCH.

[0250] If the downlink resource corresponding to a non-SBFD symbol is larger than or equal to the first frequency domain resource configured for the PDSCH, the downlink resource corresponding to the non-SBFD symbol can determine a frequency domain resource (e.g., a fifth frequency domain resource) with a bandwidth equal to that of the first frequency domain resource, and then the PDSCH can be transmitted using the fifth frequency domain resource in the first slot. Since the fifth frequency domain resource has the same bandwidth as the first frequency domain resource, smooth reception of the PDSCH can be guaranteed.

[0251] In one embodiment, the bandwidth of a first frequency domain resource can first be determined, and this bandwidth can be represented by the number of RBs, for example, k1 RBs.

[0252] For example, starting with the starting RB of the activated BWP corresponding to the first slot, k1 consecutive RBs within the activated BWP can be determined. If there are only k1-n RBs between the starting RB of the activated BWP and the first boundary of a resource other than the downlink resource (a boundary relatively close to the starting RB), then n more RBs can be determined within the downlink resource starting from the second boundary of the resource other than the downlink resource (a boundary relatively far from the starting RB), and the determined k1-n RBs and n RBs can be used as a fifth frequency domain range.

[0253] For example, using the end RB of the activated BWP corresponding to the first slot as the endpoint, k1 consecutive RBs within the activated BWP can be determined. If there are only k1-n RBs between the end RB of the activated BWP and the second boundary of a resource other than the downlink resource (a boundary relatively close to the end RB), then n more RBs can be determined within the downlink resource starting from the first boundary of the resource other than the downlink resource (a boundary relatively far from the end RB), and the determined k1-n RBs and n RBs can be used as a fifth frequency domain range.

[0254] For example, in an activated BWP, a frequency domain range having a duration of k2 consecutive RBs can be determined as a sixth frequency domain resource, and a fifth frequency domain range can be determined where the sixth frequency domain resource and the downlink resource corresponding to a non-SBFD symbol overlap, with k1 RBs.

[0255] If the downlink resource corresponding to a non-SBFD symbol is smaller than the first frequency domain resource configured for the PDSCH, a frequency domain resource equal to the bandwidth of the first frequency domain resource may not be determined for the downlink resource corresponding to the non-SBFD symbol, and the network device will not transmit the PDSCH to the terminal in the first slot.

[0256] In one embodiment, the receiving instruction method further includes the steps of: if it is determined that a PDSCH transmitted in multiple slots can be transmitted using only SBFD symbols, and there is an overlapping second frequency domain resource between a first frequency domain resource set for the PDSCH in a first slot of the multiple slots and a downlink resource corresponding to an SBFD symbol, then if the symbols occupied by the PDSCH in the first slot include non-SBFD symbols, then not transmitting the PDSCH in the first slot; and / or, if the symbols occupied by the PDSCH in the first slot include SBFD symbols and do not include uplink symbols, then transmitting the PDSCH in the first slot using the second frequency domain resource; and / or, if the symbols occupied by the PDSCH in the first slot include only SBFD symbols, then transmitting the PDSCH in the first slot using the second frequency domain resource.

[0257] In one embodiment, the network device can determine that a PDSCH transmitted through multiple slots can be sent to a terminal using only SBFD symbols, and that if there is a second overlapping frequency domain resource between a first frequency domain resource set for the PDSCH in a first slot among the multiple slots and a downlink resource corresponding to an SBFD symbol, it can further determine whether the symbols occupied by the PDSCH in the first slot include non-SBFD symbols.

[0258] For example, if the symbols occupied by the PDSCH in the first slot include non-SBFD symbols, then when the PDSCH is transmitted to the terminal in the first slot, the symbols occupied by the PDSCH will include non-SBFD symbols, thus violating the constraint that PDSCH transmitted in multiple slots can only be transmitted to the terminal using SBFD symbols. Therefore, the network device does not need to transmit PDSCH transmitted in multiple slots to the terminal in the first slot.

[0259] For example, if the symbols occupied by a PDSCH in the first slot include SBFD symbols and do not include uplink symbols, then when the PDSCH is transmitted to a terminal in the first slot, the symbols occupied by the PDSCH will include SBFD symbols, thus adhering to the constraint that PDSCHs transmitted in multiple slots can be transmitted to a terminal using only SBFD symbols. Therefore, a network device can transmit PDSCHs transmitted in multiple slots using a second frequency domain resource to a terminal in the first slot.

[0260] For example, if the symbols occupied by a PDSCH in the first slot include only SBFD symbols, then when the PDSCH is received in the first slot, the symbols occupied by the PDSCH will include only SBFD symbols, thus adhering to the constraint that PDSCHs transmitted across multiple slots can be sent to a terminal using only SBFD symbols. Therefore, a network device can send a PDSCH transmitted across multiple slots using a second frequency domain resource to a terminal from the first slot.

[0261] In one embodiment, the receiving instruction method further includes the steps of: if it is determined that a PDSCH transmitted in multiple slots can be transmitted using only non-SBFD symbols, then not transmitting the PDSCH in the first slot of the multiple slots if the symbols occupied by the PDSCH in the first slot include SBFD symbols; and / or receiving the PDSCH in the first slot if the symbols occupied by the PDSCH in the first slot include downlink symbols and / or flexible symbols, but not uplink symbols; and / or transmitting the PDSCH in the first slot if the symbols occupied by the PDSCH in the first slot include only downlink symbols and / or flexible symbols.

[0262] In one embodiment, if the network device determines that the PDSCH transmitted through multiple slots can be sent to the terminal using only non-SBFD symbols, it can further determine the symbols occupied by the PDSCH in the first slot.

[0263] For example, if the symbols occupied by the PDSCH in the first slot include SBFD symbols, then when the PDSCH is sent to the terminal in the first slot, the symbols occupied by the PDSCH will include SBFD symbols, thus violating the constraint that PDSCH transmitted in multiple slots can only be sent to the terminal with non-SBFD symbols. Therefore, the network device does not need to send PDSCH transmitted in multiple slots to the terminal in the first slot.

[0264] For example, if the symbols occupied by the PDSCH in the first slot include downlink symbols and / or flexible symbols, then when the PDSCH is transmitted to the terminal in the first slot, the symbols occupied by the PDSCH will include downlink symbols and / or flexible symbols, but not uplink symbols. Since non-SBFD symbols include downlink symbols, flexible symbols, and uplink symbols, the constraint that a PDSCH transmitted in multiple slots can be transmitted to the terminal using only non-SBFD symbols can be met. Therefore, a network device can transmit a PDSCH transmitted in multiple slots to the terminal in the first slot.

[0265] For example, when the symbols occupied by PDSCH in the first slot include only downlink symbols and / or flexible symbols, when PDSCH is transmitted to the terminal in the first slot, since the symbols occupied by PDSCH also include only downlink symbols and / or flexible symbols, the PDSCH transmitted in multiple slots can be transmitted to the terminal only with non-SBFD symbols, thus complying with the constraint. Therefore, the network device can transmit the PDSCH transmitted in multiple slots to the terminal in the first slot.

[0266] Embodiments of the present disclosure also propose a resource determination method executed by a communication system including a terminal and a network device.

[0267] The terminal is configured to determine symbols available for receiving PDSCH transmitted in multiple slots based on the first information transmitted by the network device, and the symbols include at least one of SBFD symbols and non-SBFD symbols.

[0268] The network device is configured to determine symbols available for transmitting PDSCH transmitted in multiple slots to the terminal based on the first information transmitted to the terminal, and the symbols include at least one of SBFD symbols and non-SBFD symbols.
