Description

Communication method and communication device

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on February 8, 2024, with application number 202410178285.1 and application name “Communication Method and Communication Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communications, and more particularly, to a communication method and a communication device. Background Art

[0003] Currently, when uplink information needs to be transmitted using an uplink resource within a timeslot, if the timeslot contains only subband full duplex (SBFD) symbols, uplink resource #1 for the SBFD timeslot can be determined from the resources configured for the SBFD timeslot. Alternatively, if the timeslot contains only non-SBFD symbols, uplink resource #2 for the non-SBFD timeslot can be determined from the resources configured for the non-SBFD timeslot. However, when both SBFD and non-SBFD symbols exist within the timeslot, if uplink information is to be transmitted, only uplink resource #1 for the SBFD timeslot and uplink resource #2 for the non-SBFD timeslot can be determined within the timeslot, and it is not possible to determine whether uplink resource #1 or uplink resource #2 should be used to transmit the uplink information.

[0004] Furthermore, in actual communication systems, in a mixed time slot containing both SBFD and non-SBFD symbols, if multiple uplink resources are to be transmitted and these multiple uplink resources overlap in time, it is necessary to concatenate the multiple different information carried by the multiple overlapping uplink resources through encoding to obtain a total bit sequence, and then transmit this total bit sequence on a single uplink resource. Therefore, if the payload size of the multiple overlapping uplink resources is less than the number of bits in the total bit sequence, it is necessary to re-determine an uplink resource in the mixed time slot for transmitting the total bit sequence.

[0005] Therefore, in a mixed time slot where both SBFD symbols and non-SBFD symbols exist, how to determine which resource to use to ensure the integrity of the communication system needs to be solved urgently. Summary of the Invention

[0006] The present application provides a communication method and a communication device, which can determine an uplink resource for transmitting uplink information in a mixed time slot where SBFD symbols and non-SBFD symbols coexist, so as to ensure the integrity of the communication system.

[0007] In a first aspect, a communication method is provided, the method comprising: receiving first indication information from a network device, the first indication information being used to determine first resources and second resources corresponding to first uplink information in a first time slot, the first time slot comprising sub-band full-duplex SBFD symbols and non-SBFD symbols, the first resource being used for the SBFD time slot, and the second resource being used for the non-SBFD time slot; and sending the first uplink information on a third resource in the first time slot, the third resource belonging to one of the first resource and the second resource.

[0008] Based on the above scheme, in the first time slot where both SBFD symbols and non-SBFD symbols exist, when there is first uplink information to be sent, a third resource for transmitting the first uplink information can be determined from the first resource used for the SBFD time slot and the second resource used for the non-SBFD time slot, and the third resource belongs to the first resource or the second resource. In this way, an uplink resource can be determined in the mixed time slot for transmitting the uplink information, which can take into account the existing communication system while ensuring a more complete SBFD system design.

[0009] In combination with the first aspect, in certain implementations of the first aspect, the first uplink information is sent on the third resource within the first time slot, including: when the time domain symbol index of the first resource does not include the non-SBFD symbol index in the first time slot and the time domain symbol index of the second resource does not include the SBFD symbol index in the first time slot, and / or when both the first resource and the second resource can be used for uplink transmission, the first uplink information is sent on the third resource within the first time slot.

[0010] Based on the above scheme, in the first time slot, when all symbols of the first resource in the first time slot are SBFD symbols and all symbols of the second resource in the first time slot are non-SBFD symbols, and / or when both the first resource and the second resource can be used for uplink transmission, that is, all time-frequency domain resources of the first resource and the second resource are valid uplink resources, one of the first resource and the second resource is determined as the third resource, and uplink information is sent on the determined third resource, which can effectively ensure the operation of the system and ensure that the SBFD system design is more perfect.

[0011] In combination with the first aspect, in certain implementations of the first aspect, the third resource belongs to one of the first resource and the second resource, including: when the time slot symbol index of the first resource includes the non-SBFD symbol index in the first time slot and / or the first resource cannot be used for uplink transmission, the third resource belongs to the second resource, the time domain symbol index of the second resource does not include the SBFD symbol index in the first time slot and / or the second resource can be used for uplink transmission; or, when the time slot symbol index of the second resource includes the SBFD symbol index in the first time slot and / or the second resource cannot be used for uplink transmission, the third resource belongs to the first resource, the time domain symbol index of the first resource does not include the non-SBFD symbol index in the first time slot and / or the first resource can be used for uplink transmission.

[0012] Based on the above scheme, when the time domain symbol index of the first resource includes the non-SBFD symbol index of the first time slot and / or the first resource cannot be used for uplink transmission, that is, when the first resource is an invalid resource, the third resource belongs to a valid second resource, and all symbols of the second resource in the first time slot are non-SBFD symbols and / or the second resource can be used for uplink transmission. In addition, when the time domain symbol index of the second resource includes the SBFD symbol index of the first time slot and / or the second resource cannot be used for uplink transmission, that is, when the second resource is an invalid resource, the third resource belongs to a valid first resource, and all symbols of the first resource in the first time slot are SBFD symbols and / or the first resource can be used for uplink transmission. In other words, when only one of the first resource and the second resource is valid, the third resource is the valid one of the first resource and the second resource, thereby effectively ensuring the operation of the system and ensuring a more complete design of the SBFD system.

[0013] In combination with the first aspect, in certain implementations of the first aspect, the third resource belongs to one of the first resource and the second resource, including: the third resource belongs to the one of the first resource and the second resource that is located earlier in the time domain, and / or the third resource belongs to the one of the first resource and the second resource indicated by the network device, and / or the third resource belongs to the one of the first resource and the second resource that is predefined by the protocol, and / or the third resource belongs to the one of the first resource and the second resource that does not have a frequency domain offset, and / or the third resource belongs to the one of the first resource and the second resource that has a frequency domain offset, and / or the third resource belongs to the one of the first resource and the second resource that has the same time slot type as the fourth resource, and the fourth resource is used to carry the first downlink information, and the first uplink information includes feedback information of the first downlink information.

[0014] When the first resource used for the SBFD time slot is obtained by adding a frequency domain offset to the second resource used for the non-SBFD time slot, the first resource is the one that has the frequency domain offset, and the second resource is the one that has not the frequency domain offset.

[0015] Based on the above scheme, the party with a forward position in the time domain and / or the party indicated by the network device and / or the party predefined by the protocol and / or the party without frequency domain offset and / or the party with frequency domain offset and / or the party with the same time slot type as the fourth resource used to carry the first downlink information can be determined from the first resource and the second resource. That is, based on the above multiple conditions, one party can be determined from the first resource and the second resource for transmitting uplink information, thereby effectively ensuring the operation of the system and ensuring a more complete design of the SBFD system.

[0016] In combination with the first aspect, in certain implementations of the first aspect, when the third resource belongs to the one of the first resource and the second resource indicated by the network device, the method also includes: receiving downlink control information DCI, which is used to indicate the one of the first resource and the second resource to which the third resource belongs.

[0017] Based on the above solution, one of the first resource and the second resource can be determined to be used for transmitting uplink information according to the instruction of the DCI, thereby effectively ensuring the operation of the system and ensuring a more complete design of the SBFD system.

[0018] In combination with the first aspect, in certain implementations of the first aspect, the method also includes: receiving second indication information from a network device, the second indication information being used to determine a fifth resource and a sixth resource corresponding to the second uplink information in a first time slot, the first time slot containing sub-band full-duplex SBFD symbols and non-SBFD symbols, the fifth resource being used for the SBFD time slot, and the sixth resource being used for the non-SBFD time slot; and sending the first uplink information using a seventh resource in the first time slot, the seventh resource belonging to one of the fifth resource and the sixth resource.

[0019] In combination with the first aspect, in certain implementations of the first aspect, the first uplink information is sent using the seventh resource within the first time slot, including: when the time domain symbol index of the fifth resource does not include the non-SBFD symbol index in the first time slot and the time domain symbol index of the sixth resource does not include the SBFD symbol index in the first time slot, and / or when both the fifth resource and the sixth resource can be used for uplink transmission, the first uplink information is sent using the seventh resource within the first time slot.

[0020] In combination with the first aspect, in certain implementations of the first aspect, the seventh resource belongs to one of the fifth resource and the sixth resource, including: when the time slot symbol index of the fifth resource includes the non-SBFD symbol index in the first time slot and / or the fifth resource cannot be used for uplink transmission, the seventh resource belongs to the sixth resource, the time domain symbol index of the sixth resource does not include the SBFD symbol index in the first time slot and / or the sixth resource can be used for uplink transmission; or, when the time slot symbol index of the sixth resource includes the SBFD symbol index in the first time slot and / or the sixth resource cannot be used for uplink transmission, the seventh resource belongs to the fifth resource, the time domain symbol index of the fifth resource does not include the non-SBFD symbol index in the first time slot and / or the fifth resource can be used for uplink transmission.

[0023] Based on the above solution, in the first time slot where both SBFD symbols and non-SBFD symbols exist, one of the fifth and sixth resources configured for the SBFD time slot can be determined as the seventh resource according to certain rules, such as the one with a forward time domain position between the fifth and sixth resources. The seventh resource is used to transmit the second uplink information. That is, an uplink resource is determined in the mixed time slot for transmitting the second uplink information. This ensures that the existing communication system is taken into account while ensuring a more complete SBFD system design.

[0024] In combination with the first aspect, in certain implementations of the first aspect, when the third resource overlaps with the seventh resource in the time domain, the method also includes: receiving third indication information from the network device, the third indication information being used to determine an eighth resource and a ninth resource corresponding to the first uplink information and the second uplink information in the first time slot, the first time slot containing sub-band full-duplex SBFD symbols and non-SBFD symbols, the eighth resource being used for the SBFD time slot, and the ninth resource being used for the non-SBFD time slot; and the tenth resource in the first time slot being used to send the first uplink information and the second uplink information, the tenth resource belonging to one of the eighth resource and the ninth resource.

[0025] In combination with the first aspect, in certain implementations of the first aspect, the first uplink information and the second uplink information are sent using the tenth resource within the first time slot, including: when the time domain symbol index of the eighth resource does not include the non-SBFD symbol index in the first time slot, the time domain symbol index of the ninth resource does not include the SBFD symbol index in the first time slot, and / or when both the eighth resource and the ninth resource can be used for uplink transmission, the first uplink information and the second uplink information are sent using the tenth resource within the first time slot.

[0026] In combination with the first aspect, in certain implementations of the first aspect, the tenth resource belongs to one of the eighth resource and the ninth resource, including: when the time slot symbol index of the eighth resource includes the non-SBFD symbol index in the first time slot and / or the eighth resource cannot be used for uplink transmission, the tenth resource belongs to the ninth resource, the time domain symbol index of the ninth resource does not include the SBFD symbol index in the first time slot and / or the ninth resource can be used for uplink transmission; or, when the time slot symbol index of the ninth resource includes the SBFD symbol index in the first time slot and / or the ninth resource cannot be used for uplink transmission, the tenth resource belongs to the eighth resource, the time domain symbol index of the eighth resource does not include the non-SBFD symbol index in the first time slot and / or the eighth resource can be used for uplink transmission.

[0029] Based on the above scheme, in the first time slot where SBFD symbols and non-SBFD symbols coexist, if the third resource used to transmit the first uplink information and the seventh resource used to transmit the second uplink information overlap in the time domain, the first uplink information and the second uplink information need to be put together on a new resource that can carry the first uplink information and the second uplink information for transmission. Therefore, it is necessary to determine one of the eighth resource and the ninth resource corresponding to the first uplink information and the second uplink information according to certain rules in the first time slot, for transmitting the first uplink information and the second uplink information.

[0071] It should be understood that in some scenarios, a UE can also be used to act as a base station. For example, a UE can act as a scheduling entity that provides sidelink signals between UEs in scenarios such as V2X, D2D, or P2P.

[0080] For ease of understanding, the following describes a communication system applicable to the embodiments of the present application. It should be understood that the following communication system is only an example, and the communication system applicable to the present application is not limited thereto.

[0081] Figure 1 is a schematic diagram of the architecture of a mobile communication system 100 applicable to an embodiment of the present application. As shown in Figure 1 , the mobile communication system includes a core network device 110, a radio access network device 120, and at least one terminal device (such as terminal device 130 and terminal device 140 in Figure 1 ). The terminal device is wirelessly connected to the radio access network device, and the radio access network device is wirelessly or wiredly connected to the core network device. The core network device and the radio access network device can be independent and distinct physical devices, or the core network device's functions and the radio access network device's logical functions can be integrated into the same physical device, or a single physical device can integrate some of the core network device's functions and some of the radio access network device's functions. The terminal device can be fixed or mobile. Figure 1 is merely a schematic diagram, and the communication system may also include other network devices, such as wireless relay devices and wireless backhaul devices, which are not shown in Figure 1 . The embodiments of the present application do not limit the number of core network devices, radio access network devices, and terminal devices included in the mobile communication system.

[0082] The embodiments of the present application can be applied to downlink signal transmission, uplink signal transmission, and D2D signal transmission. For downlink signal transmission, the transmitting device is a wireless access network device, and the corresponding receiving device is a terminal device. For uplink signal transmission, the transmitting device is a terminal device, and the corresponding receiving device is a wireless access network device. For D2D signal transmission, the transmitting device is a terminal device, and the corresponding receiving device is also a terminal device. The embodiments of the present application are not limited to the transmission direction of the signals.

[0083] The wireless access network device and the terminal device, as well as the terminal device and the terminal device, can communicate through the licensed spectrum (licensed spectrum), or can communicate through the unlicensed spectrum (unlicensed spectrum), or can communicate through the licensed spectrum and the unlicensed spectrum at the same time. The wireless access network device and the terminal device, as well as the terminal device and the terminal device, can communicate through the spectrum below 6G, or can communicate through the spectrum above 6G, or can communicate through the spectrum below 6G and the spectrum above 6G at the same time. The embodiments of the present application do not limit the spectrum resources used between the wireless access network device and the terminal device.

[0084] Figure 2 shows the three duplexing modes in NR. Currently, NR has frequency division duplex (FDD) and time division duplex (TDD).

[0085] FDD: As shown in Figure 2(a), frequency division dual (FDD) has two bandwidth parts (BWPs). The upper half of Figure 2(a) is the downlink (D) bandwidth, and the lower half is the uplink (U) bandwidth. As shown in Figure 2(a), in time slot 0, the terminal device can perform downlink transmissions on the downlink bandwidth part (DL BWP). The terminal device can also perform uplink transmissions on the uplink bandwidth part (UL BWP) of time slot 0. The DL BWP and UL BWP are located on different carriers and are separated in the frequency domain.

[0086] TDD: As shown in (b) of Figure 2, the center frequency of the DL BWP and the UL BWP are the same, and the bandwidths of the DL BWP and UL BWP can be the same or different. At the same time, the terminal device can only perform uplink or downlink transmission. For example, in time slot 0, only downlink transmission can be performed; in time slot 4, only uplink transmission can be performed; time slot 3 is a flexible (F) time slot, which can be used for both uplink and downlink transmission, but uplink and downlink transmission cannot be performed simultaneously on the same symbol in time slot 3. The minimum granularity of uplink and downlink transmission switching is the symbol. For example, time slot 3 is a mixed time slot, consisting of 14 or 12 orthogonal frequency division multiplexing (OFDM) symbols. In one possible case, when time slot 3 consists of 14 symbols, the first M symbols are downlink symbols, the last N symbols are uplink symbols, and the symbols other than M and N symbols are flexible symbols, where 0≤M≤14, 0≤N≤14, and M+N≤14. Downlink symbols are used for downlink transmission, uplink symbols are used for uplink transmission, and flexible symbols can be used for both uplink and downlink transmission. The specific transmission direction is notified to the terminal device by the network equipment through radio resource control (RRC) signaling or downlink control information (DCI) scheduling.

[0087] Compared with FDD, TDD occupies fewer frequency domain resources. However, in TDD, uplink and downlink transmissions cannot be performed simultaneously in one time slot. For example, time slot 0 can only be used for downlink transmission, not uplink transmission, which will increase the uplink transmission delay.

[0088] To address TDD latency issues, the standard proposes flexible duplexing, which can be understood as complementary TDD (C-TDD), full duplex, subband full duplex (SBFD), or other names. The core concept of SBFD is that uplink and downlink transmission resources can be configured simultaneously within a symbol or time slot in a TDD system. For example, as shown in Figure 2 (c), in time slot 0, a frequency domain resource exists within the downlink BWP that can be used for uplink transmission. Therefore, uplink transmission can be performed in time slot 0, reducing uplink transmission latency. This uplink frequency domain resource is typically called an uplink subband. Furthermore, downlink transmission can also be performed in time slot 0. Network devices can perform simultaneous uplink and downlink transmissions in time slot 0. Terminal devices can also perform simultaneous uplink and downlink transmissions in time slot 0. For example, a full-duplex terminal device can perform simultaneous uplink and downlink transmissions in time slot 0. Terminal devices can also perform only uplink or downlink transmission, such as half-duplex terminal devices. Compared with TDD, SBFD has more uplink resources and can improve uplink coverage.

[0089] Currently, the standard proposes that a time slot can be composed of SBFD symbols and non-SBFD (non-SBFD) symbols, but it is unknown whether a channel / signal transmission is allowed to be mapped to both SBFD and non-SBFD symbols. In addition, the standard also proposes that the channel sounding reference signal (SRS), physical uplink control channel (PUCCH), and physical uplink shared channel (PUSCH) can be configured with different resources and parameters for SBFD symbols and non-SBFD symbols in different time slots. Currently, when there is a piece of information that needs to be transmitted through an uplink resource in a time slot, when there are only SBFD symbols in the time slot, the resource to be used can be determined from the resources configured for the SBFD symbols in the time slot; or, when there are only non-SBFD symbols in the time slot, the resource to be used can also be determined from the resources configured for the non-SBFD symbols in the time slot.

[0090] Figure 3 is a schematic diagram of the PUCCH resources carrying hybrid automatic repeat request-acknowledgement (HARQ-ACK). As shown in Figure 3, time slots 0 to 3 are the time slots where SBFD symbols are located, and time slots 3 to 4 are the time slots where non-SBFD symbols are located. It can be seen that there are both SBFD symbols and non-SBFD symbols in time slot 3. It should be understood that Figure 3 is only a schematic diagram, and the time domain positions and frequency domain positions of SBFD symbols and non-SBFD symbols in time slot 3 are for reference only. For the convenience of description, the PUCCH resources used to transmit HARQ-ACK messages are referred to as HARQ-ACK PUCCH resources below. PUCCH#1 is the HARQ-ACK PUCCH resource for SBFD symbols, and PUCCH#2 is the HARQ-ACK PUCCH resource for non-SBFD symbols. As can be seen from Figure 3, in time slot 0, since there are only SBFD symbols, if a HARQ-ACK message needs to be sent, the current terminal device can confirm the use of PUCCH#1 to transmit the HARQ-ACK from the PUCCH configured for multiple SBFD symbols in time slot 0. Similarly, in time slots 1 and 2, since there are only SBFD symbols, when a HARQ-ACK message needs to be transmitted in time slot 1 or time slot 2, the terminal device can confirm the use of PUCCH#1. In addition, in time slot 4, there are only non-SBFD symbols. According to the current protocol, if a HARQ-ACK message needs to be sent, the terminal device can also determine the use of PUCCH#2 to transmit the HARQ-ACK.

[0091] However, when both SBFD and non-SBFD symbols exist in a time slot, as shown in Figure 3, there are both SBFD and non-SBFD symbols in time slot 3. According to the current protocol, if HARQ-ACK information needs to be sent at this time, only PUCCH#1 can be determined from multiple PUCCHs configured for SBFD symbols, and PUCCH#2 can be determined from multiple PUCCHs configured for non-SBFD symbols, but it is impossible to determine whether PUCCH#1 or PUCCH#2 is used. Therefore, in a mixed (flexible) time slot with both SBFD and non-SBFD symbols, when different resources are configured for SBFD and non-SBFD symbols, how to determine which symbol's resources to use needs to be solved urgently.

[0092] In an actual communication system, when multiple different information needs to be transmitted, the multiple different information may be transmitted through different uplink resources in one time slot. The uplink resources corresponding to different information may overlap in time. At this time, it is necessary to multiplex the different information and determine an uplink resource for transmission at that time.

[0093] The following example illustrates NR uplink multiplexing using uplink resources carrying different uplink control information (UCI). In the NR standard, uplink channels include but are not limited to PUCCH and PUSCH.

[0094] PUCCH can carry UCI, including scheduling request SR, hybrid automatic repeat request confirmation HARQ-ACK, channel state information CSI, etc. For multiple uplink carriers in the same PUCCH group, PUCCH will be sent on at most one uplink carrier at the same time. If two or more PUCCHs carrying different UCI overlap in time, these UCIs need to be carried together on the same PUCCH and sent. The PUCCH used for transmission can be one of the original two or more PUCCHs or a new PUCCH. This process is called UCI multiplexing on PUCCH. Since each UCI is a bit sequence, different bit sequences can be concatenated and jointly encoded or independently encoded and concatenated, and finally a total bit sequence is output and mapped to the PUCCH. The purpose of determining a new PUCCH is that when the payload of two or more PUCCHs that overlap in time and carry different UCI is less than the number of bits in the final output bit sequence, the original two or more PUCCHs can no longer be used to carry the final output bit sequence, and therefore a new PUCCH needs to be determined to carry the bit sequence.

[0095] The PUSCH is used to carry uplink data and / or aperiodic CSI. For multiple uplink carriers within the same PUCCH group, if PUCCH and PUSCH overlap at the same time, both cannot be transmitted simultaneously, regardless of whether they are on the same uplink carrier. Depending on the UCI content carried on the PUCCH, the UCI can be placed on the PUSCH and transmitted along with the data, a process known as UCI piggyback. Alternatively, the UCI can be multiplexed onto the PUSCH. Alternatively, the UCI can be discarded and only the PUSCH can be transmitted.

[0096] Figure 4 is a flowchart of the uplink multiplexing described above. As shown in Figure 4, if there are multiple PUCCHs that overlap in time, the UCI carried on these multiple PUCCHs must first be multiplexed onto a single PUCCH. This PUCCH can be any one of these multiple PUCCHs, or a newly determined PUCCH. Secondly, if the PUCCH and PUSCH overlap at the same time, multiplexing between the PUCCH and PUSCH is performed. The final output may be either a PUCCH or a PUSCH. As can be seen from the above, this PUSCH may or may not carry the UCI on the PUCCH.

[0097] Therefore, to ensure the integrity of the communication system design, if multiple uplink resources need to be sent on a mixed time slot that contains both SBFD symbols and non-SBFD symbols, it is necessary to determine whether the multiple uplink resources overlap in time. If overlap occurs, and a new uplink resource needs to be determined, and the information carried by the multiple uplink resources overlapping in the time domain needs to be multiplexed onto the newly determined uplink resource for transmission, how to determine the multiplexed uplink resource on the mixed time slot needs to be solved urgently.

[0098] Figure 5 is a schematic flow chart of a communication method 200 provided in an embodiment of the present application. As shown in Figure 5, the method 200 may include the following steps.

[0099] S210: The network device sends a first indication message to the terminal device, where the first indication information is used to determine uplink resource #1 and uplink resource #2. Accordingly, the terminal device receives the first indication information from the network device.

[0100] The first indication information is used to indicate SBFD parameters, parameters for uplink resources for non-SBFD, and parameters for uplink resources for SBFD. The terminal device can determine uplink resource #1 for the SBFD timeslot based on the parameters for the uplink resources for SBFD, and determine uplink resource #2 for the non-SBFD timeslot based on the parameters for the uplink resources for non-SBFD. Uplink resource #1 is an example of the first resource, and uplink resource #2 is an example of the second resource.

[0101] SBFD parameters include, but are not limited to, the following parameters: SBFD time slot index and SBFD subband position within the SBFD time slot. An SBFD time slot can be a DL time slot or a partial time slot within a UL time slot configured in the TDD parameters, or a time slot that is different from the three types of time slots in the TDD parameters. An SBFD subband position can be the frequency domain position of a UL subband and / or a DL subband.

[0102] Uplink resource parameters for non-SBFD include but are not limited to the following parameters: time domain location of uplink resources, frequency domain location of uplink resources, etc. Uplink resource parameters for non-SBFD may be one or more of RRC parameters, MAC-CE parameters, and DCI.

[0103] The parameters for uplink resources used for SBFD can be configured in the following two ways:

[0104] Method 1: Uplink resource parameters for non-SBFD are configured in the same manner as for "Uplink resource parameters for non-SBFD," including but not limited to the time domain location and frequency domain location of the uplink resources for SBFD. In other words, uplink resources for non-SBFD and uplink resources for SBFD are configured independently. In this case, uplink resource parameters for SBFD can be one or more of the following: RRC parameters, MAC-CE parameters, and DCI.

[0105] Method 2: Based on the "uplink resource parameters for non-SBFD", a frequency domain offset is configured for SBFD uplink resources. This frequency domain offset can be configured separately for each "uplink resource for non-SBFD", or a common frequency domain offset can be configured for all "uplink resources for non-SBFD". This frequency domain offset can be configured independently for a specific cell, a specific carrier, a specific bandwidth part (BWP), each PUCCH format, or each PUCCH resource. This frequency domain offset is configured for the uplink resources for SBFD relative to the uplink resources for non-SBFD. In other words, the "uplink resources for SBFD" can be obtained by adding the configured frequency domain offset value to the "uplink resources for non-SBFD".

[0106] It should be understood that when the network device adopts the configuration method of method 1, the parameters of the uplink resources for SBFD sent by the network device to the terminal device include but are not limited to: the time domain position of the uplink resources for SBFD, the frequency domain position of the uplink resources for SBFD, etc. When the network device adopts the configuration method of method 2, the parameters of the uplink resources for SBFD sent by the network device to the terminal device include a frequency domain offset for SBFD, so that the uplink resources for SBFD can be obtained by adding the frequency domain offset value to the uplink resources used for non-SBFD.

[0107] The parameters of the uplink resources for SBFD are used to determine the uplink resources for the SBFD timeslot, and the parameters of the uplink resources for non-SBFD are used to determine the uplink resources for the non-SBFD timeslot.

[0108] S220. The terminal device determines the uplink resource #3 that meets the preset conditions based on the resource type and the first indication information.

[0109] In one possible implementation, the terminal device determines, based on the first indication information, uplink resource #1 and uplink resource #2 corresponding to the first uplink information in the first time slot, where the first time slot includes sub-band full-duplex SBFD symbols and non-SBFD symbols, uplink resource #1 is used for the SBFD time slot, uplink resource #2 is used for the non-SBFD time slot, the SBFD time slot does not include non-SBFD symbols, and the non-SBFD time slot does not include SBFD symbols; in the first time slot, uplink resource #3 that meets a preset condition is used to send the first uplink information, where the preset condition is used to determine that one of uplink resource #1 and uplink resource #2 is uplink resource #3. Uplink resource #3 is an example of a third resource. Accordingly, the network device receives the first uplink information from the terminal device.

[0110] The uplink resource #1 is a resource determined among the uplink resources used for the SBFD timeslot, and the uplink resource #2 is a resource determined among the uplink resources used for the non-SBFD timeslot.

[0111] It is understood that a time slot is composed of symbols. For example, a time slot may be composed of 14 or 12 symbols. Therefore, uplink resource #1 may be a resource for SBFD symbols determined according to the first indication information, and uplink resource #2 may be a resource for non-SBFD symbols determined according to the first indication information. Both uplink resource #1 and uplink resource #2 may be used to transmit the first uplink information.

[0112] Specifically, for a time slot in which both SBFD symbols and non-SBFD symbols exist, the terminal device determines uplink resource #3 according to the resource type and the parameters indicated by the first indication information. The resource type includes resources for SBFD symbols and resources for non-SBFD symbols.

[0113] The uplink resources may include resources used for uplink transmission, such as PUCCH and PUSCH.

[0114] When the parameters of the uplink resources for SBFD indicated by the first indication information do not include frequency domain offset, or when the network device independently configures uplink resource #1 for SBFD and uplink resource #2 for non-SBFD using method one, within the mixed time slot, one party can be determined from uplink resource #1 and uplink resource #2 according to the following preset conditions. The determined party is uplink resource #3, and the first uplink information is transmitted on uplink resource #3.

[0115] In a possible implementation, the uplink resource #3 is an uplink resource that meets a first condition: the uplink resource #3 is the one with the earlier starting symbol in the time domain between the uplink resource #1 and the uplink resource #2.

[0116] For example, time slot 3 in Figure 3 is used as an example. As can be seen from the above, time slot 3 is a mixed time slot with both SBFD symbols and non-SBFD symbols. When UCI#1 information needs to be transmitted, a PUCCH needs to be determined for the transmission of UCI#1. The terminal device determines PUCCH#1 for the SBFD time slot and PUCCH#2 for the non-SBFD time slot based on the first indication information, and based on the time domain position of PUCCH#1 for the SBFD time slot and the time domain position of PUCCH#2 for the non-SBFD time slot indicated by the first indication information, determines PUCCH#1 with a closer time domain position in time slot 3 for transmitting UCI#1.

[0117] In one possible implementation, uplink resource #3 is an uplink resource that satisfies a second condition. The second condition is that uplink resource #3 is one of uplink resource #1 and uplink resource #2 indicated by a network device or predefined by a protocol. In other words, uplink resource #3 is one of uplink resource #1 and uplink resource #2 indicated by a network device or predefined by a protocol.

[0118] Exemplarily, time slot 3 in Figure 3 is used as an example. As can be seen from the above, time slot 3 is a mixed time slot with both SBFD symbols and non-SBFD symbols. When there is a UCI#1 information that needs to be transmitted, a PUCCH needs to be determined for the transmission of UCI#1. The terminal device determines the PUCCH#1 for the SBFD time slot and the PUCCH#2 for the non-SBFD time slot based on the first indication information, and can determine whether to use PUCCH#1 or PUCCH#2 based on the network device indication or protocol pre-definition. For example, if the network device indicates or the protocol pre-defines the use of PUCCH#1, the terminal device ultimately determines to use PUCCH#1 to transmit UCI#1. If the network device indicates or the protocol pre-defines the use of PUCCH#2, the terminal device ultimately determines to use PUCCH#2 to transmit UCI#1.

[0119] In a possible implementation, when the starting symbol of the uplink resource #1 used for the SBFD time slot and the uplink resource #2 used for the non-SBFD time slot in the time domain is the same symbol, the uplink resource #3 can also be the one of the uplink resource #1 and the uplink resource #2 that meets the second condition.

[0120] For example, time slot 3 in Figure 3 is used as an example. As can be seen from the above, time slot 3 is a mixed time slot with both SBFD symbols and non-SBFD symbols. When there is a UCI#1 information that needs to be transmitted, a PUCCH needs to be determined for the transmission of UCI#1. The terminal device determines the PUCCH#1 for the SBFD time slot and the PUCCH#2 for the non-SBFD time slot based on the first indication information, and determines that the starting symbol of PUCCH#1 and PUCCH#2 is the same based on the time domain position of PUCCH#1 for the SBFD time slot and the time domain position of PUCCH#2 for the non-SBFD time slot indicated by the first indication information. The terminal device can determine whether to use PUCCH#1 or PUCCH#2 based on the network device indication or protocol pre-definition. For example, if the network device indicates or the protocol pre-defines the use of PUCCH#1, the terminal device ultimately determines to use PUCCH#1 to transmit UCI#1. If the network device instructs or the protocol predefines the use of PUCCH#2, the terminal device finally determines to use PUCCH#2 to transmit UCI#1.

[0121] In one possible implementation, when uplink resource #3 is one of uplink resource #1 and uplink resource #2 indicated by the network device, the terminal device may further receive downlink control information DCI from the network device. Accordingly, the network device may further send DCI to the terminal device, where uplink resource #3 is one of uplink resource #1 and uplink resource #2 indicated by the DCI. Uplink resource #3 is an uplink resource that satisfies the third condition, which is that uplink resource #3 is one of uplink resource #1 and uplink resource #2 indicated by the DCI.

[0122] Specifically, the terminal device can also receive DCI information of semi-persistent scheduling (Semi-persistent Scheduling, SPS) from the network device, and needs to receive SPS PDSCH in response to the DCI information, and send SPS PDSCH HARQ-ACK feedback information to the network device. Therefore, the terminal device needs to determine a PUCCH for transmitting SPS PDSCH HARQ-ACK feedback information. That is, when PUCCH is used to transmit SPS PDSCH HARQ-ACK message, for the convenience of description, the PUCCH resource used to transmit SPS PDSCH HARQ-ACK message is referred to as SPS PDSCH HARQ-ACK PUCCH resource. The terminal device can activate the PUCCH resource indication field in the DCI according to the SPS transmission to indicate one of uplink resource #1 and uplink resource #2, that is, uplink resource #3 can be one of uplink resource #1 and uplink resource #2 indicated by the DCI of semi-persistent scheduling. In other words, uplink resource #3 is an uplink resource that meets the third condition. The third condition is that uplink resource #3 is either uplink resource #1 or uplink resource #2 as indicated by the PUCCH resource indication field in the SPS transmission activation DCI. Furthermore, for DCI information dynamically sent by a network device, the terminal device may also determine uplink resource #3 based on either uplink resource #1 or uplink resource #2 as indicated by the DCI. In summary, uplink resource #3 may be either uplink resource #1 or uplink resource #2 as indicated by the DCI.

[0123] For example, time slot 3 in Figure 3 is used as an example. As can be seen from the above, time slot 3 is a mixed time slot with both SBFD symbols and non-SBFD symbols. When the feedback information HARQ-ACK#1 corresponding to DCI#1 needs to be transmitted, a PUCCH needs to be determined for the transmission of HARQ-ACK#1. The terminal device can determine the PUCCH#1 for the SBFD time slot and the PUCCH#2 for the non-SBFD time slot based on the first indication information. The terminal device can determine to use PUCCH#1 according to the indication of the PUCCH resource indication field in the SPS transmission activation DCI, that is, the uplink resources for the SBFD symbols to transmit HARQ-ACK#1; or the terminal device can also determine to use PUCCH#2 according to the indication of the PUCCH resource indication field in the SPS transmission activation DCI, that is, the resources for non-SBFD symbols to transmit HARQ-ACK#1.

[0124] In one possible implementation, uplink resource #3 is an uplink resource that meets the fourth condition. The fourth condition is that uplink resource #3 is the one of uplink resource #1 and uplink resource #2 that has the same timestamp type as resource #4, and resource #4 is used to carry first downlink information, where the first uplink information includes feedback information about the first downlink information. Resource #4 is an example of a fourth resource.

[0125] Specifically, when the first uplink information is the feedback information HARQ-ACK of the PDSCH corresponding to the DCI, the terminal device can determine from uplink resource #1 and uplink resource #2 that the party with the same symbol type as the PDSCH resource is located according to the symbol (time slot) type of the physical downlink shared channel (PDSCH) resource (resource #4) as uplink resource #3. In other words, the uplink resource #3 is an uplink resource that meets the fourth condition. The fourth condition is that the uplink resource #3 is a HARQ-ACK PUCCH resource with the same symbol type as the PDSCH. The symbol (or time slot) type includes the SBFD symbols and non-SBFD symbols mentioned above. The HARQ-ACK PUCCH resource is an example of uplink resource #3.

[0126] For example, time slot 3 in Figure 3 is used as an example. As can be seen from the above, time slot 3 is a mixed time slot with both SBFD symbols and non-SBFD symbols. When feedback information HARQ-ACK#1 corresponding to DCI#1 needs to be transmitted, a PUCCH needs to be determined for the transmission of HARQ-ACK#1. The terminal device can determine PUCCH#1 for the SBFD time slot and PUCCH#2 for the non-SBFD time slot based on the first indication information. The terminal device can determine from uplink resource #1 and uplink resource #2 that the one with the same symbol type as the PDSCH is uplink resource #3. The PDSCH is the resource for transmitting DCI#1, and uplink resource #3 is used to transmit feedback information HARQ-ACK#1 for DCI#1. If the symbol type of the PDSCH is an SBFD symbol, uplink resource #3 is PUCCH#1; if the symbol type of the PDSCH is a non-SBFD symbol, uplink resource #3 is PUCCH#2.

[0127] When the parameters of the uplink resources used for SBFD indicated by the first indication information include frequency domain offset, or when the network device configures uplink resource #1 for the SBFD time slot using method two, that is, uplink resource #1 for the SBFD time slot is obtained by adding frequency domain offset configuration to uplink resource #2 for the non-SBFD time slot, within the mixed time slot, one party can be determined from uplink resource #1 and uplink resource #2 according to the following preset conditions, and the determined party is uplink resource #3, and the first uplink information is transmitted on uplink resource #3.

[0128] In one possible implementation, the terminal device can determine uplink resource #3 based on the frequency domain offset. Specifically, the protocol predefines or the network device indicates whether the frequency domain offset is used to configure the uplink resources for the SBFD timeslot. When the uplink resources for the SBFD timeslot are derived from the uplink resources for the non-SBFD timeslot plus the frequency domain offset, the uplink resources for the SBFD timeslot that are subject to the frequency domain offset are those for the SBFD timeslot. In other words, the implementation of the frequency domain offset indicates the use of the "uplink resources for the SBFD timeslot." The uplink resources for the non-SBFD timeslot that do not experience the frequency domain offset are those for the non-SBFD timeslot. In other words, the ineffectiveness of the frequency domain offset indicates the use of the "uplink resources for the non-SBFD timeslot." Whether the frequency domain offset is effective can be understood as whether the uplink resources are subject to the frequency domain offset. For example, as shown above, the terminal device configures the "uplink resources for the SBFD timeslot" by adding the configured frequency domain offset. Therefore, the "uplink resources for the SBFD timeslot" that are subject to the frequency domain offset are those for the non-SBFD timeslot, while the "uplink resources for the non-SBFD timeslot" are those that do not experience the frequency domain offset. Therefore, the terminal device can determine uplink resource #3 based on whether frequency domain offset occurs. When the network device indicates or the protocol predefines the use of frequency domain offset to configure the uplink resources for the SBFD time slot, uplink resource #3 is the uplink resource #1 for the SBFD time slot with frequency domain offset. If the network device indicates or the protocol predefines the use of frequency domain offset to configure the uplink resources for the SBFD time slot, uplink resource #3 is the uplink resource #2 for the non-SBFD time slot with no frequency domain offset. Uplink resource #3 is the one between uplink resource #1 and uplink resource #2 that meets the fifth condition. The fifth condition is that uplink resource #3 is the one between uplink resource #1 and uplink resource #2 that has or does not have a frequency domain offset.

[0129] For example, time slot 3 in Figure 3 is used as an example. As can be seen from the above, time slot 3 is a mixed time slot that contains both SBFD symbols and non-SBFD symbols. When UCI#1 information needs to be transmitted, a PUCCH needs to be determined for the transmission of UCI#1. The terminal device can determine PUCCH#1 for the SBFD time slot and PUCCH#2 for the non-SBFD time slot based on the first indication information. When the network device indicates or the protocol stipulates the use of frequency domain offset to configure uplink resources for the SBFD time slot, the uplink resources for the SBFD time slot are frequency-offset. For example, the uplink resource PUCCH#2 used by the network device for the non-SBFD time slot occupies 10 RBs in the frequency domain (RB#n to RB#n+9), and the frequency domain offset is 5 RBs. Since the uplink resource for the SBFD time slot is configured using frequency domain offset, the uplink resource PUCCH#1 used for the SBFD time slot occupies 10 RBs in the frequency domain (RB#n+5 to RB#n+14). Therefore, the terminal device uses PUCCH#1 (RB#n+5 to RB#n+14) for SBFD time slots with frequency domain offset to transmit UCI#1. In one possible scenario, when the possible bandwidth of PUCCH#2 is the entire bandwidth of the BWP, that is, the entire uplink bandwidth in the frequency domain of the non-SBFD symbols in the DL BWP in time slot 3, PUCCH#2 will not be frequency offset at this time, so PUCCH#1 is ultimately determined to be used to transmit UCI#1. Conversely, if the terminal device does not use frequency domain offset to configure uplink resources for SBFD time slots, PUCCH#2 for non-SBFD time slots without frequency domain offset is used to transmit UCI#1.

[0130] It should be noted that when the network device uses method 2 to configure the uplink resources for the SBFD time slot, the uplink resource #1 used for the SBFD time slot and the uplink resource #2 used for the non-SBFD time slot must occupy the same symbols in the time domain, that is, the starting symbol is the same, the ending symbol is the same, and the number of occupied symbols is the same. The only difference is the frequency domain position. For example, the starting symbol and ending symbol occupied by PUCCH #1 and PUCCH #2 are exactly the same. Therefore, the terminal device can determine whether to use PUCCH #1 or PUCCH #2 based on whether the frequency domain position of PUCCH #1 or PUCCH #2 is frequency domain offset. For details, see the above description of uplink resource #3 determined based on frequency domain offset, which will not be repeated here.

[0131] It should also be noted that whether the frequency domain offset is effective can be used to indicate whether the uplink resources for the SBFD time slot or the uplink resources for the non-SBFD time slot are used, that is, "frequency domain offset is effective" indicates the use of "uplink resources for the SBFD time slot", and "frequency domain offset is not effective" indicates the use of "uplink resources for the non-SBFD time slot".

[0132] It should be noted that, when the starting symbol of uplink resource #1 and uplink resource #2 is the same symbol, that is, the starting position of uplink resource #1 and uplink resource #2 in the time domain is the same, the terminal device can determine one of uplink resource #1 and uplink resource #2 to send the first uplink information according to the second condition and / or the third condition and / or the fourth condition and / or the fifth condition. For example, when the starting symbol of uplink resource #1 and uplink resource #2 is the same symbol, it can also be determined as uplink resource #3 according to the uplink resource #1 and uplink resource #2 indicated by the network device or predefined by the protocol. When the starting symbols of uplink resource #1 and uplink resource #2 are different, that is, the starting positions of uplink resource #1 and uplink resource #2 in the time domain are different, the terminal device can also directly determine whether to use uplink resource #1 or uplink resource #2 according to the second condition and / or the third condition and / or the fourth condition. That is to say, the above preset conditions may be used in combination to determine uplink resource #3, or the above preset conditions may be used alone to determine uplink resource #3, and this application does not impose any limitation on this.

[0133] In a possible implementation, the terminal device may determine uplink resource #3 that satisfies some of the above preset conditions for uplink information of a specific type. For uplink information other than the specific type, the terminal device may determine uplink resource #3 based on conditions other than the preset conditions.

[0134] For example, the terminal device may determine uplink resource #3 that satisfies the first condition for a specific type of UCI. For example, for SPS PDSCH HARQ-ACK, scheduling request (SR), and channel state information (CSI) semi-statically configured via RRC signaling, uplink resource #3 that satisfies the first condition may be determined based on the first condition. For UCI with PUCCH resources dynamically indicated by DCI, the PUCCH carrying the UCI may be directly indicated by the DCI.

[0135] In a possible implementation, the terminal device may use different preset conditions to determine uplink resource #3 for different types of uplink information.

[0136] Exemplarily, UCI may be HARQ-ACK, SR, or CSI. For HARQ-ACK, PUCCH#1 that satisfies the first condition may be determined from PUCCH#1 and PUCCH#2 based on a first condition. For SR and CSI, PUCCH#2 that satisfies the second condition may be determined from PUCCH#1 and PUCCH#2 based on a second condition. It should be understood that the above-mentioned PUCCHs carrying HARQ-ACK, SR, and CSI are merely examples. HARQ-ACK may also determine PUCCH#2 that satisfies the second condition from PUCCH#1 and PUCCH#2 based on a second condition. SR and CSI may also determine PUCCH#1 that satisfies the first condition from PUCCH#1 and PUCCH#2 based on a first condition.

[0137] Based on the above scheme, in a time slot containing both SBFD and non-SBFD symbols, the terminal device can, based on preset conditions, determine one of the two, uplink resource #1 for the SBFD time slot and uplink resource #2 for the non-SBFD time slot, as uplink resource #3 for transmitting the first uplink information. This balances scheduling flexibility and signaling overhead, ensuring a more comprehensive SBFD system design. Furthermore, different preset conditions can be used to determine the uplink resource for transmitting the uplink information, providing greater flexibility in the use of conditions.

[0138] In one possible implementation, the terminal device may determine that one of uplink resource #1 and uplink resource #2 is uplink resource #3 based on whether the uplink resource is valid. In other words, uplink resource #3 is an uplink resource that satisfies the sixth condition: that uplink resource #3 is a valid uplink resource #1 or uplink resource #2.

[0139] The definition of whether uplink resources are valid is as follows.

[0140] Definition 1: The time-domain symbol index of uplink resource #1 used in an SBFD time slot does not include a non-SBFD symbol index in the first time slot, and the time-domain symbol index of uplink resource #2 used in a non-SBFD time slot does not include a SBFD symbol index in the first time slot. The first time slot is a mixed time slot containing both SBFD and non-SBFD symbols. In other words, a valid uplink resource #1 is one in which all symbols of uplink resource #1 in the first time slot are SBFD symbols, and a valid uplink resource #2 is one in which all symbols of uplink resource #2 in the first time slot are non-SBFD symbols.

[0141] Definition 2. Uplink resource #1 used for an SBFD timeslot and uplink resource #2 used for a non-SBFD timeslot can both be used for uplink transmission. That is, all time-frequency resources of uplink resource #1 can be used for uplink transmission, and all time-frequency resources of uplink resource #2 can be used for uplink transmission. In other words, all time-frequency resources of uplink resource #1 and uplink resource #2 are uplink resources. In other words, valid uplink resource #1 is a resource that can be used for uplink transmission, and valid uplink resource #2 is a resource that can be used for uplink transmission.

[0142] For example, Figure 6 is a schematic diagram of PUCCH resources in a mixed time slot. As shown in Figure 6, according to Definition 1, it can be seen from the time domain that the symbols where PUCCH#1 is located are all SBFD symbols, and the symbols where PUCCH#2 is located are all non-SBFD symbols. The symbols where PUCCH#3 and PUCCH#4 are located have both SBFD symbols and non-SBFD symbols. Therefore, PUCCH#3 and PUCCH#4 are both invalid resources, because PUCCH#3 and PUCCH#4 do not belong to any type of symbol resources, and the terminal device will not determine a resource from PUCCH#3 and PUCCH#4. PUCCH#1 is a valid uplink resource for SBFD, but an invalid uplink resource for non-SBFD. PUCCH#2 is a valid uplink resource for non-SBFD, but an invalid uplink resource for SBFD. According to Definition 2, all time-frequency resources of PUCCH#1, PUCCH#2, and PUCCH#3 are uplink resources. Therefore, PUCCH#1 to PUCCH#3 are all valid resources. A part of PUCCH#4 in the frequency domain does not belong to uplink resources, so PUCCH#4 is an invalid resource.

[0143] It should be understood that uplink resource #3 is a valid uplink resource selected and determined by the terminal device based on the parameter information indicated by the first indication information from multiple uplink resources configured by the network device.

[0144] In a possible implementation, when only uplink resource #1 is valid among uplink resource #1 used for the SBFD time slot and uplink resource #2 used for the non-SBFD time slot, uplink resource #3 belongs to uplink resource #1; when only uplink resource #2 is valid among uplink resource #1 used for the SBFD time slot and uplink resource #2 used for the non-SBFD time slot, uplink resource #3 belongs to uplink resource #2.

[0145] In one possible implementation, when the uplink resource #1 used for the SBFD time slot and the uplink resource #2 used for the non-SBFD time slot are both valid resources, within the first time slot, the terminal device can determine one of the uplink resource #1 and the uplink resource #2 as the uplink resource #3 based on the first to fifth conditions.

[0146] In one possible implementation, when uplink resource #1 for an SBFD timeslot and uplink resource #2 for a non-SBFD timeslot are both invalid resources, and uplink information #1 is to be sent in the first timeslot, the terminal device may not send this uplink information #1. Alternatively, this uplink information #1 may be multiplexed onto the uplink resource carrying uplink information #2 for transmission.

[0147] Based on the above solution, in a mixed time slot of an SBFD system containing both SBFD and non-SBFD symbols, a terminal device can determine, based on valid definition conditions, whether uplink resource #1 for the SBFD time slot and uplink resource #2 for the non-SBFD time slot are valid. If only one is valid, that uplink resource is used as uplink resource #3 to transmit the first uplink information. If both uplink resource #1 and uplink resource #2 are valid, then one of them is determined based on the first to fifth conditions and the first uplink information is transmitted, thereby ensuring that the resulting uplink resource is valid, or that the uplink resource is capable of uplink transmission. This can more effectively guarantee system operation and ensure a more complete SBFD system design.

[0148] Based on the above scheme, when UCI#1 is to be transmitted in a mixed timeslot in an SBFD system, the uplink resource to be used for transmitting UCI#1 can be determined based on the first to sixth conditions mentioned above, from uplink resource#1 used for the SBFD timeslot and uplink resource#2 used for the non-SBFD timeslot. However, in an actual communication system, there may be multiple different UCIs to be transmitted, and these different UCIs can be transmitted via multiple PUCCHs. That is, UCI#1 can be sent via PUCCH#1, UCI#2 can be sent via PUCCH#2, UCI#3 can be sent via PUCCH#3, and so on. However, these PUCCHs carrying different UCIs may overlap in the time domain. As can be seen from the above, when overlap occurs in the time domain, the different UCIs need to be multiplexed onto a single PUCCH. This PUCCH can be any one of the multiple PUCCHs carrying different UCIs, or a newly determined PUCCH. Therefore, when it is necessary to re-determine a PUCCH for sending the multiplexed UCI, for the multiplexing process mentioned above, there are the following ways to determine the uplink resources before and after multiplexing.

[0149] The first method

[0150] 1. Before multiplexing, in the first time slot, for multiple different uplink information, the first uplink information and the second uplink information are used to illustrate. From the above, it can be seen that the uplink resource #3 used to send the first uplink information can be determined according to the first to fifth conditions mentioned above. Similarly, the uplink resource #4 used to send the second uplink information can also be determined according to the first to fifth conditions mentioned above.

[0151] Exemplarily, before multiplexing, that is, when there are multiple different UCIs to be transmitted, in a mixed time slot having both SBFD symbols and non-SBFD symbols, the terminal device can determine multiple PUCCHs for transmitting each of the multiple different UCIs based on the first to fifth conditions. For example, the terminal device determines that PUCCH#1 is transmitted for UCI#1; PUCCH#2 is transmitted for UCI#2; and PUCCH#n is transmitted for UCI#n, where n≥2.

[0152] 2. Determine whether uplink resources carrying different uplink information overlap in the time domain. If so, multiplexing is performed. This means that the uplink information carried by multiple uplink resources that overlap in the time domain is concatenated through coding to obtain a total bit sequence. Because the total bit sequence is greater than the maximum payload of each of the overlapping uplink resources, a new uplink resource is determined to transmit the total bit sequence. For example, if uplink resource #3 and uplink resource #4 overlap in the time domain, multiplexing is performed.

[0153] Exemplarily, the terminal device determines whether the n PUCCHs overlap in the time domain based on the parameters of the uplink resources for SBFD and the uplink resources for non-SBFD indicated by the first indication information. If they overlap, they need to be multiplexed. For example, PUCCH#1 and PUCCH#j overlap in the time domain, and UCI#1 and UCI#j need to be multiplexed together into a new PUCCH, 2≤j≤n. That is, UCI#1 and UCI#j can be cascaded and jointly encoded or independently encoded and cascaded, and the final output total bit sequence needs to be mapped to a new PUCCH. The terminal device needs to determine the new PUCCH after multiplexing.

[0154] 3. After multiplexing, in the first time slot, for the total bit sequence, if the terminal device determines that only one of uplink resource #1 and uplink resource #2 is valid according to the sixth condition, then uplink resource #5 used to transmit the total bit sequence can be valid uplink resource #1 or valid uplink resource #2. If the terminal device determines that both uplink resource #1 and uplink resource #2 are valid resources according to the sixth condition, it can also determine one of uplink resource #1 and uplink resource #2 as uplink resource #5 according to the first to fifth conditions, and uplink resource #5 is used to transmit the total bit sequence.

[0155] For example, after multiplexing, that is, when the total bit sequence needs to be mapped to a new PUCCH, the terminal device can determine a valid one from PUCCH#1 used for the SBFD time slot and PUCCH#2 used for the non-SBFD time slot according to the sixth condition, for transmitting the total bit sequence. If the terminal device determines that there are two valid PUCCHs according to the sixth condition, that is, both PUCCH#1 and PUCCH#2 are valid resources, it can also determine, according to the first to fifth conditions, one of the two valid PUCCHs for transmitting the total bit sequence.

[0156] For the sake of brevity, the following description uses the uplink information as UCI and the uplink resource as PUCCH to exemplify the multiplexing process in the mixed timeslot.

[0157] Second method

[0158] 1. Before multiplexing, in the first time slot, that is, when there are multiple different UCIs to be transmitted, multiple PUCCHs for transmitting each of the different UCIs can be determined based on the sixth condition. For example, the terminal device determines based on the sixth condition that PUCCH#1 is used to transmit UCI#1; PUCCH#2 is used to transmit UCI#2; and PUCCH#n is used to transmit UCI#n, where n≥2. Each of the multiple PUCCHs is a valid one of PUCCH#1 for the SBFD time slot and PUCCH#2 for the non-SBFD time slot, determined based on the sixth condition. If both PUCCH#1 for the SBFD time slot and PUCCH#2 for the non-SBFD time slot, determined based on the sixth condition, are valid resources, the terminal device further determines from PUCCH#1 and PUCCH#2 a PUCCH for transmitting each UCI based on the first to fifth conditions.

[0159] 2. The terminal device determines whether the n PUCCHs overlap in the time domain based on the parameters indicated by the first indication information. If so, they need to be multiplexed. For example, if PUCCH#1 and PUCCH#j overlap in the time domain, UCI#1 and UCI#j need to be multiplexed together into a new PUCCH, where 2≤j≤n. In other words, UCI#1 and UCI#j can be concatenated and jointly encoded or independently encoded and concatenated. The final output bit sequence needs to be mapped to a new PUCCH, and the terminal device needs to determine the multiplexed PUCCH.

[0160] 3. After multiplexing, in the first time slot, that is, when the total bit sequence needs to be mapped to a new PUCCH, the terminal device can determine a valid PUCCH from PUCCH#1 used for the SBFD time slot and PUCCH#2 used for the non-SBFD time slot according to the sixth condition, that is, PUCCH#1 or PUCCH#2 is used to transmit the total bit sequence. If the terminal device determines two valid PUCCHs according to the sixth condition, that is, both PUCCH#1 and PUCCH#2 are valid resources, it can also determine one of the two valid PUCCHs according to the first to fifth conditions to transmit the total bit sequence.

[0161] The third way

[0162] 1. Before multiplexing, in the first time slot, that is, when there are multiple different UCIs to be transmitted, the terminal device can determine multiple PUCCHs for transmitting each of the multiple different UCIs based on the first to fifth conditions. For example, the terminal device determines that PUCCH #1 is used to transmit UCI #1; PUCCH #2 is used to transmit UCI #2; and PUCCH #n is used to transmit UCI #n, where n ≥ 2.

[0163] 2. The terminal device determines whether the n PUCCHs overlap in the time domain based on the parameters indicated by the first indication information. If so, they need to be multiplexed. For example, if PUCCH#1 and PUCCH#j overlap in the time domain, UCI#1 and UCI#j need to be multiplexed together into a new PUCCH, where 2≤j≤n. In other words, UCI#1 and UCI#j can be concatenated and jointly encoded or independently encoded and concatenated. The final output bit sequence needs to be mapped to a new PUCCH, and the terminal device needs to determine the multiplexed PUCCH.

[0164] 3. After multiplexing, in the first time slot, that is, when the total bit sequence needs to be mapped to a new PUCCH, the terminal device can determine, based on the first to fifth conditions, which party is used to transmit the total bit sequence from PUCCH#1 used for the SBFD time slot and PUCCH#2 used for the non-SBFD time slot. That is to say, the terminal device determines the multiplexed PUCCH for transmitting the total bit sequence in the first time slot based on the first to fifth conditions.

[0165] Based on the above scheme, the uplink resources before and after multiplexing are determined by the above three methods to improve the processing flow of uplink multiplexing in mixed time slots where SBFD symbols and non-SBFD symbols coexist, thereby ensuring a more complete SBFD system design.

[0166] The above describes in detail the communication method provided by the present application. The following describes the communication device provided by the present application.

[0167] In order to realize the various functions of the communication devices (such as network devices, terminal devices) in the embodiments of the present application, each communication device can realize the corresponding functions through hardware structure, software module, or hardware structure plus software module.

[0168] Figure 7 is a schematic block diagram of a communication device 1000 provided in an embodiment of the present application.
