[0030] Figure 1 This is a schematic diagram illustrating an application scenario according to an embodiment of the present disclosure.

[0031] like Figure 1 As shown, the embodiments of this disclosure can be applied to scenarios where terminals communicate with network devices, but are not limited to this scenario. Figure 1 The entities shown are illustrative; the implementation methods or embodiments of this disclosure may include... Figure 1 All or part of the main body, or may include Figure 1 Other entities besides these, the number of each entity is arbitrary, not limited to Figure 1 . Figure 1 The connections shown are illustrative. Any entities may be connected or not connected, and the connection can be in any way, whether it is a direct or indirect connection, a wired connection or a wireless connection.

[0032] In one embodiment, the terminal includes, but is not limited to, communication devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices. The terminal can communicate with network devices, including, but not limited to, network devices in 4G, 5G, and 6G communication systems, such as base stations and core networks.

[0033] Figure 2 This is a schematic diagram illustrating uplink and downlink resources according to embodiments of the present disclosure.

[0034] like Figure 2As shown, the network device configures an uplink sub-band for the terminal in the downlink time domain resources (e.g., semi-static downlink symbols). The uplink sub-band is the uplink resource. The frequency domain resources outside the uplink sub-band and the guard band in the corresponding downlink time domain resources are the downlink resources. The downlink resources can also be called downlink sub-bands. A guard band is set between the downlink resources and the uplink resources. The guard band is not used to transmit information, including data and / or signals, thereby achieving frequency domain isolation to a certain extent and avoiding interference between uplink and downlink communication.

[0035] It should be noted that the embodiments of this disclosure are applicable to both situations where a protection band is provided between downlink and uplink resources and situations where no protection band is provided between downlink and uplink resources. The following embodiments illustrate this disclosure in the case where a protection band is provided between downlink and uplink resources.

[0036] The terminal can perform uplink transmission in the uplink subband of the downlink time domain resources. The terminal can be a full-duplex terminal or a legacy terminal; a legacy terminal can be a half-duplex terminal. The network device can be a full-duplex network device, capable of receiving uplink transmissions from the terminal in the uplink subband of the downlink time domain resources. It can also send (e.g., broadcast) synchronization signal blocks (SSBs) to terminals in the cell within the frequency domain resources corresponding to the downlink time domain resources, excluding the uplink subband.

[0037] In this scenario, the SSB and uplink transmission overlap in the downlink time domain resources. The terminal's uplink transmission can cause cross-link interference (CLI) to the downlink transmission (such as the SSB mentioned above), leading to problems in the terminal's SSB reception.

[0038] The embodiments disclosed herein can be applied to the scenario where the SSB and uplink transmission overlap in downlink time domain resources, as well as to other scenarios where the SSB and uplink transmission overlap in time domain resources.

[0039] Figure 3 This is a schematic flowchart illustrating a synchronization signal block receiving method according to an embodiment of the present disclosure. The synchronization signal block receiving method shown in this embodiment can be executed by a terminal.

[0040] like Figure 3 As shown, the synchronization signal block receiving method may include the following steps:

[0041] In step S301, it is determined that the synchronization signal block overlaps with the uplink transmission in the uplink subband in terms of time domain resources;

[0042] In step S302, the method for receiving the synchronization signal block is determined based on the instruction information sent by the network device, or the method for receiving the synchronization signal block is determined according to the protocol agreement.

[0043] Uplink transmission can include sending data to network devices, or it can include sending signaling to network devices.

[0044] This disclosure does not limit this.

[0045] In one embodiment, the uplink transmission includes at least one of the following:

[0046] Uplink transmission on dynamically scheduled resources, such as dynamically scheduled PUSCH (Physical Uplink Shared Channel);

[0047] Uplink transfers on pre-configured resources, such as CG PUSCH, where CG can be translated as configured grant.

[0048] In one embodiment, the overlap of SSB with uplink transmission in time domain resources includes at least one of the following:

[0049] The first time domain unit where the SSB is located partially overlaps with the second time domain unit where the uplink transmission is located.

[0050] The first time domain unit where the SSB is located completely overlaps with the second time domain unit where the uplink transmission is located.

[0051] Figures 4A to 4C This is a schematic diagram illustrating the overlap of synchronization signal blocks and uplink transmissions in the time domain resources according to embodiments of the present disclosure.

[0052] Taking the overlap of SSB and uplink transmission in downlink time slots as an example, that is, the aforementioned time domain resources include downlink time slots, in this case, the time slot can be called a Sub-Band Full Duplex (SBFD) time slot. The overlap of SSB and uplink transmission in time domain resources can include... Figures 4A to 4C Any one of the following situations.

[0053] like Figure 4A The time domain resources where the SSB resides completely overlap with the time domain resources where the uplink transmission resides. For example... Figure 4B As shown, the time domain resources where the SSB is located partially overlap with the time domain resources where the uplink transmission is located. As shown in 4C, the time slot where the SSB is located overlaps with the time slot where the uplink transmission is located, but within the overlapping time slots, the time domain resources where the SSB is located do not overlap with the symbols where the uplink transmission is located.

[0054] In one embodiment, the uplink subband includes at least one of the following:

[0055] Uplink subbands configured in a flexible time-domain unit;

[0056] Uplink subband configured in the downlink time domain unit.

[0057] The time-domain unit includes at least one of the following: frame, subframe, time slot, symbol, which can be an OFDM (Orthogonal Frequency Division Multiplexing) symbol.

[0058] Because SSB and uplink transmission overlap in time domain resources, uplink transmission may cause cross-link interference to SSB, which may lead to problems in terminal reception of SSB.

[0059] According to embodiments of this disclosure, when the SSB and uplink transmission overlap in time domain resources, the terminal can determine how to receive the SSB according to the instructions of the network device or the protocol agreement, so that the terminal can receive the SSB in a definite manner, which helps to ensure that the terminal receives the SSB correctly.

[0060] In one embodiment, determining how to receive the synchronization signal block according to the protocol includes:

[0061] According to the agreement, a synchronization signal block is received when the number of frequency domain units of the synchronization signal block and the uplink transmission interval is greater than or equal to a first number.

[0062] In one embodiment, the time-domain unit includes at least one of the following: a resource element (RE) and a resource block (RB).

[0063] Taking a time-domain unit including RBs as an example, if the first number is T, the terminal does not expect the frequency domain interval between the SSB and the uplink transmission to be less than T RBs. Correspondingly, the network device will not configure the frequency domain interval between the transmitted SSB and the terminal's uplink transmission to be less than T RBs. Therefore, the terminal can receive the SSB if the number of RBs between the SSB and the uplink transmission is greater than or equal to T.

[0064] According to embodiments of this disclosure, since the SSB and uplink transmission are spaced relatively far apart in the frequency domain, for example, the number of frequency domain units between them is greater than or equal to a first number, a greater degree of frequency domain isolation will be generated. Even if the time domain resources of the SSB and uplink transmission overlap, the interference caused by the uplink transmission to the SSB will be relatively small, which is beneficial to the reception quality of the SSB.

[0065] In one embodiment, the synchronization signal block receiving method further includes at least one of the following:

[0066] The first number shall be determined in accordance with the agreement;

[0067] The first number is determined based on the capability information of the terminal sent to the network device;

[0068] The first number is determined based on the signaling sent by the network device.

[0069] In one embodiment, the first number may be agreed upon by a protocol. In another embodiment, the first number may be indicated by the network device, for example, by the network device through signaling. In yet another embodiment, the network device may send capability information to the terminal, for example, capability information indicating that when the SSB and the uplink transmission time domain resources overlap, the terminal supports receiving the SSB when the SSB and the uplink transmission are separated by a first number of frequency domain units in the frequency domain, then the first number can be determined to be the first number indicated in the capability information.

[0070] In one embodiment, the synchronization signal block receiving method further includes: determining that a case where the number of frequency domain units between the synchronization signal block and the uplink subband spacing is less than a second number is an error.

[0071] When the number of frequency domain units between the SSB and the uplink subband is less than the second number, it can be determined that the SSB and the uplink subband are separated by a large frequency domain, and the interference of the uplink subband to the SSB is relatively strong. The terminal cannot ensure the reception quality of the SSB, so this situation can be identified as an error case.

[0072] In case of an error, the terminal can choose to perform only uplink transmission on time-domain resources where SSB and uplink transmission overlap, or to receive only SSB, in order to ensure that at least one of the uplink and downlink transmissions can proceed successfully.

[0073] In one embodiment, determining how to receive the synchronization signal block according to the protocol includes: receiving the synchronization signal block when the time domain resources where the synchronization signal block is located are not being transmitted uplink, according to the protocol.

[0074] In one embodiment, the terminal may not expect uplink transmissions on the time domain resources where the SSB resides, for example, if the time domain resources where the SSB resides include symbols. Correspondingly, the network device will not schedule the terminal to perform uplink transmissions on the time domain resources where the SSB resides.

[0075] Therefore, the terminal can receive the SSB even when the time domain resources where the SSB is located are not used for uplink transmission. Since the time domain resources where the SSB is located are not used for uplink transmission, the uplink transmission will not interfere with the SSB reception process, thus ensuring good SSB reception quality.

[0076] In one embodiment, uplink transmission is not performed on the time domain resources where the synchronization signal block resides, including one of the following:

[0077] We do not expect the resources in the first time domain where the synchronization signal block is located to overlap with the resources in the second time domain where the uplink transmission is located.

[0078] Uplink transmission is performed on time domain resources in the second time domain resources that do not overlap with the first time domain resources.

[0079] In one embodiment, not uplink transmission occurs in the time domain resources where the synchronization signal block resides. This may include the terminal not expecting the first time domain resources where the synchronization signal block resides to overlap with the second time domain resources where uplink transmission occurs. Correspondingly, the network device sends the first time domain resources where the SSB resides to the terminal, which do not overlap with the second time domain resources where the scheduling terminal performs uplink transmission. Since the first time domain resources where the SSB resides do not overlap with the second time domain resources where uplink transmission occurs, the uplink transmission will not interfere with the SSB reception process, ensuring good SSB reception quality.

[0080] In one embodiment, not performing uplink transmission on the time domain resources where the synchronization signal block resides can include performing uplink transmission on time domain resources in the second time domain resources that do not overlap with the first time domain resources. The first time domain resources where the network device sends the SSB to the terminal can overlap with the second time domain resources where the scheduling terminal performs uplink transmission. However, the terminal only performs uplink transmission on time domain resources in the second time domain resources that do not overlap with the first time domain resources. Therefore, the time domain resources actually used for uplink transmission do not overlap with the first time domain resources where the SSB resides. Thus, the uplink transmission will not interfere with the SSB reception process, ensuring good SSB reception quality.

[0081] In one embodiment, determining how to receive the synchronization signal block based on the indication information sent by the network device includes:

[0082] Based on the indication information, it is determined whether the synchronization signal block can be received or uplink transmission cannot be performed on the time domain resources that overlap with the synchronization signal block and uplink transmission, and the synchronization signal block is received on the overlapping time domain resources.

[0083] The indication information includes at least one of the following: system information, System Information Block (SIB), and Radio Resource Control (RRC) signaling. The proportion of indication information can be set as needed; for example, the indication information and its content are shown in Table 1.

[0084]

[0085] Table 1

[0086] As shown in Table 1, for example, the indication information occupies 1 bit. When the indication information is 0, it can indicate that the SSB can be received on the time domain resources overlapping with the uplink transmission, or it can indicate that uplink transmission cannot be performed on the time domain resources overlapping with the SSB. When the indication information is 1, it can indicate that the SSB cannot be received on the time domain resources overlapping with the uplink transmission, or it can indicate that uplink transmission can be performed on the time domain resources overlapping with the SSB.

[0087] In one embodiment, the network device may send indication information to the terminal, which indicates whether the terminal can receive the SSB or perform uplink transmission on time domain resources where the SSB and uplink transmission overlap.

[0088] Specifically, when the indication information indicates that the terminal can receive the SSB on time-domain resources overlapping with the uplink transmission, or when the indication information indicates that the terminal cannot perform uplink transmission on time-domain resources overlapping with the SSB, the terminal can determine that it can receive the SSB on the overlapping time-domain resources but cannot perform uplink transmission. Since the SSB can be received on the overlapping time-domain resources but uplink transmission cannot be performed, the uplink transmission will not interfere with the SSB reception process, thus ensuring good SSB reception quality.

[0089] When the indication information indicates that the terminal cannot receive an SSB on time-domain resources overlapping with uplink transmission, or when the indication information indicates that the terminal can perform uplink transmission on time-domain resources overlapping with SSB transmission, the terminal can determine that it cannot receive an SSB on the overlapping time-domain resources, but can perform uplink transmission. Since uplink transmission can perform on overlapping time-domain resources, it will interfere with the SSB reception process. Therefore, on overlapping time-domain resources, it is possible to perform only uplink transmission and not receive an SSB.

[0090] Figure 5 This is a schematic flowchart illustrating another synchronization signal block receiving method according to an embodiment of the present disclosure. The synchronization signal block receiving method shown in this embodiment can be executed by a terminal.

[0091] like Figure 5 As shown, the synchronization signal block receiving method further includes:

[0092] In step S501, capability indication information is sent to the network device, wherein the capability indication information is used to indicate that the terminal supports receiving the synchronization signal block when the synchronization signal block overlaps with the uplink transmission in the time domain.

[0093] It should be noted that, Figure 5 The embodiments shown can be implemented independently or in combination with at least one other embodiment of this disclosure. The specific choice can be made as needed, and this disclosure does not limit the scope of the embodiments.

[0094] In one embodiment, the terminal may send capability indication information to the network device to indicate whether the terminal supports receiving SSB when SSB and uplink transmission overlap in time domain resources.

[0095] If the terminal supports receiving SSBs when SSBs and uplink transmissions overlap in the time domain resources, the network device can configure the terminal to send SSBs to the terminal in the time domain resources when the terminal performs uplink transmissions.

[0096] If the terminal does not support receiving SSBs when the SSB and uplink transmission overlap in the time domain resources, the network device may not send SSBs to the terminal on the time domain resources when configuring the terminal for uplink transmission; or, when sending SSBs to the terminal on the time domain resources, it may not configure the terminal for uplink transmission on the time domain resources. Correspondingly, the terminal does not expect the time domain resources where the SSB resides to overlap with the time domain resources where the uplink transmission resides.

[0097] Figure 6 This is a schematic flowchart illustrating a synchronization signal block transmission method according to an embodiment of the present disclosure. The synchronization signal block transmission method shown in this embodiment can be executed by a network device, which can communicate with a terminal. The network device includes, but is not limited to, base stations in communication systems such as 4G base stations, 5G base stations, and 6G base stations. The terminal includes, but is not limited to, communication devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices.

[0098] like Figure 6 As shown, the method for transmitting synchronization signal blocks may include the following steps:

[0099] In step S601, it is determined that the synchronization signal block overlaps with the uplink transmission in the uplink subband configured for the terminal in the time domain resources;

[0100] In step S602, the method for sending a synchronization signal block to the terminal is determined based on the instruction information sent to the terminal, or the method for sending a synchronization signal block to the terminal is determined based on the protocol agreement.

[0101] Uplink transmission can include sending data to network devices, or it can include sending signaling to network devices.

[0102] This disclosure does not limit this.

[0103] In one embodiment, the uplink transmission includes at least one of the following:

[0104] Uplink transmission on dynamically scheduled resources, such as dynamically scheduled PUSCH;

[0105] Uplink transmissions on pre-configured resources, such as CG PUSCH.

[0106] In one embodiment, the overlap of SSB with uplink transmission in time domain resources includes at least one of the following:

[0107] The first time domain unit where the SSB is located partially overlaps with the second time domain unit where the uplink transmission is located.

[0108] The first time domain unit where the SSB is located completely overlaps with the second time domain unit where the uplink transmission is located.

[0109] In one embodiment, determining how to send a synchronization signal block to the terminal according to the protocol includes: sending a synchronization signal block to the terminal when the number of frequency domain units of the synchronization signal block and the uplink transmission interval is greater than or equal to a first number, according to the protocol.

[0110] In one embodiment, the uplink subband includes at least one of the following:

[0111] Uplink subbands configured in a flexible time-domain unit;

[0112] Uplink subband configured in the downlink time domain unit.

[0113] The time-domain unit includes at least one of the following: frame, subframe, time slot, symbol, which may be an OFDM symbol.

[0114] Since SSB and uplink transmission overlap in time domain resources, there is a problem that uplink transmission can cause cross-link interference to SSB, which can lead to problems in the terminal's reception of SSB.

[0115] According to embodiments of this disclosure, when the SSB overlaps with the uplink transmission in the uplink subband configured for the terminal in the time domain, the network device can determine how to send the SSB to the terminal based on the instruction information or protocol agreement sent to the terminal. Correspondingly, the terminal can also determine how to receive the SSB based on the instruction information or protocol agreement, thereby enabling the network device and the terminal to reach a consistent way to send and receive the SSB, which is beneficial to ensuring that the terminal receives the SSB correctly.

[0116] In one embodiment, determining how to send a synchronization signal block to the terminal according to the protocol includes: sending a synchronization signal block to the terminal when the number of frequency domain units of the synchronization signal block and the uplink transmission interval is greater than or equal to a first number, according to the protocol.

[0117] In one embodiment, the time-domain unit includes at least one of the following: resource element (RE) and resource block (RB).

[0118] Taking a time-domain unit including RBs as an example, if the first number is T, the terminal does not expect the frequency domain interval between the SSB and the uplink transmission to be less than T RBs. Correspondingly, the network device will not configure the frequency domain interval between the transmitted SSB and the terminal's uplink transmission to be less than T RBs. Therefore, the terminal can receive the SSB if the number of RBs between the SSB and the uplink transmission is greater than or equal to T.

[0119] According to embodiments of this disclosure, since the SSB and uplink transmission are spaced relatively far apart in the frequency domain, for example, the number of frequency domain units between them is greater than or equal to a first number, a greater degree of frequency domain isolation will be generated. Even if the time domain resources of the SSB and uplink transmission overlap, the interference caused by the uplink transmission to the SSB will be relatively small, which is beneficial to the reception quality of the SSB.

[0120] In one embodiment, the synchronization signal block transmission method further includes at least one of the following:

[0121] The first number shall be determined in accordance with the agreement;

[0122] The first number is determined based on the terminal's capability information;

[0123] The first number is determined based on the signaling sent to the terminal.

[0124] In one embodiment, the first number may be agreed upon by a protocol. In another embodiment, the first number may be indicated by the network device, for example, by the network device through signaling. In yet another embodiment, the network device may send capability information to the terminal, for example, capability information indicating that when the SSB and the uplink transmission time domain resources overlap, the terminal supports receiving the SSB when the SSB and the uplink transmission are separated by a first number of frequency domain units in the frequency domain, then the first number can be determined to be the first number indicated in the capability information.

[0125] In one embodiment, determining how to send a synchronization signal block to the terminal according to the protocol includes: sending the synchronization signal block to the terminal when the time domain resources where the synchronization signal block is located are not being transmitted uplink, according to the protocol.

[0126] In one embodiment, the terminal may not expect uplink transmissions on the time domain resources where the SSB resides, for example, if the time domain resources where the SSB resides include symbols. Correspondingly, the network device will not schedule the terminal to perform uplink transmissions on the time domain resources where the SSB resides.

[0127] Therefore, the terminal can receive the SSB even when the time domain resources where the SSB is located are not used for uplink transmission. Since the time domain resources where the SSB is located are not used for uplink transmission, the uplink transmission will not interfere with the SSB reception process, thus ensuring good SSB reception quality.

[0128] In one embodiment, uplink transmission is not performed on the time domain resources where the synchronization signal block resides, including one of the following:

[0129] The first time domain resources where the synchronization signal block is sent to the terminal do not overlap with the second time domain resources where the terminal performs uplink transmission.

[0130] The uplink transmission of the terminal is received on a time domain resource in the second time domain resource that does not overlap with the first time domain resource.

[0131] In one embodiment, not uplink transmission occurs in the time domain resources where the synchronization signal block resides. This may include the terminal not expecting the first time domain resources where the synchronization signal block resides to overlap with the second time domain resources where uplink transmission occurs. Correspondingly, the network device sends the first time domain resources where the SSB resides to the terminal, which do not overlap with the second time domain resources where the scheduling terminal performs uplink transmission. Since the first time domain resources where the SSB resides do not overlap with the second time domain resources where uplink transmission occurs, the uplink transmission will not interfere with the SSB reception process, ensuring good SSB reception quality.

[0132] In one embodiment, not performing uplink transmission on the time domain resources where the synchronization signal block resides can include performing uplink transmission on time domain resources in the second time domain resources that do not overlap with the first time domain resources. The first time domain resources where the network device sends the SSB to the terminal can overlap with the second time domain resources where the scheduling terminal performs uplink transmission. However, the terminal only performs uplink transmission on time domain resources in the second time domain resources that do not overlap with the first time domain resources. Therefore, the time domain resources actually used for uplink transmission do not overlap with the first time domain resources where the SSB resides. Thus, the uplink transmission will not interfere with the SSB reception process, ensuring good SSB reception quality.

[0133] In one embodiment, determining how to receive a synchronization signal block based on the instruction information sent to the terminal includes: determining, based on the instruction information, whether the terminal can receive the synchronization signal block or the terminal cannot perform uplink transmission on the time domain resources overlapping with the synchronization signal block, and sending the synchronization signal block to the terminal on the overlapping time domain resources.

[0134] The indication information includes at least one of the following: system information, System Information Block (SIB), and Radio Resource Control (RRC) signaling. The number of bits allocated to the indication information can be set as needed; for example, the indication information and its content are shown in Table 1 of the previous embodiments. For example, if the indication information occupies 1 bit, when the indication information is 0, it can indicate that an SSB can be received on time-domain resources overlapping with uplink transmission, or it can indicate that uplink transmission cannot be performed on time-domain resources overlapping with uplink transmission. When the indication information is 1, it can indicate that an SSB cannot be received on time-domain resources overlapping with uplink transmission, or it can indicate that uplink transmission can be performed on time-domain resources overlapping with uplink transmission.

[0135] In one embodiment, the network device may send indication information to the terminal, which indicates whether the terminal can receive the SSB or perform uplink transmission on time domain resources where the SSB and uplink transmission overlap.

[0136] Specifically, when the indication information indicates that the terminal can receive the SSB on time-domain resources overlapping with the uplink transmission, or when the indication information indicates that the terminal cannot perform uplink transmission on time-domain resources overlapping with the SSB, the terminal can determine that it can receive the SSB on the overlapping time-domain resources but cannot perform uplink transmission. Since the SSB can be received on the overlapping time-domain resources but uplink transmission cannot be performed, the uplink transmission will not interfere with the SSB reception process, thus ensuring good SSB reception quality.

[0137] When the indication information indicates that the terminal cannot receive an SSB on time-domain resources overlapping with uplink transmission, or when the indication information indicates that the terminal can perform uplink transmission on time-domain resources overlapping with SSB transmission, the terminal can determine that it cannot receive an SSB on the overlapping time-domain resources, but can perform uplink transmission. Since uplink transmission can perform on overlapping time-domain resources, it will interfere with the SSB reception process. Therefore, on overlapping time-domain resources, it is possible to perform only uplink transmission and not receive an SSB.

[0138] In one embodiment, the synchronization signal block transmission method further includes: receiving capability indication information sent by the terminal, wherein the capability indication information is used to indicate that the terminal supports receiving the synchronization signal block when the synchronization signal block overlaps with the uplink transmission in the time domain.

[0139] In one embodiment, the terminal may send capability indication information to the network device to indicate whether the terminal supports receiving SSB when SSB and uplink transmission overlap in time domain resources.

[0140] If the terminal supports receiving SSBs when SSBs and uplink transmissions overlap in the time domain resources, the network device can configure the terminal to send SSBs to the terminal in the time domain resources when the terminal performs uplink transmissions.

[0141] If the terminal does not support receiving SSBs when the SSB and uplink transmission overlap in the time domain resources, the network device may not send SSBs to the terminal on the time domain resources when configuring the terminal for uplink transmission; or, when sending SSBs to the terminal on the time domain resources, it may not configure the terminal for uplink transmission on the time domain resources. Correspondingly, the terminal does not expect the time domain resources where the SSB resides to overlap with the time domain resources where the uplink transmission resides.

[0142] It should be noted that other contents involved in this embodiment are described in the previous embodiments, and will not be repeated here.
