Communication method and related apparatus

Abstract

A communication method and a related apparatus. In the communication method, a terminal device receives a first message from a network device, the first message comprising first configuration information and second configuration information. The first configuration information is used for indicating that a configuration type of transmission performed by using a first physical uplink control channel (PUCCH) resource is a first configuration type or a second configuration type. The second configuration information indicates that a symbol used for transmitting first uplink control information (UCI) is a subband full duplex (SBFD) symbol or a non-SBFD symbol. Transmission performed by using a PUCCH resource corresponding to the first configuration type can be carried in an SBFD symbol or a non-SBFD symbol. Transmission performed by using a PUCCH resource corresponding to the second configuration type may be carried in an SBFD symbol and a non-SBFD symbol. On the basis of the first configuration information and the second configuration information, the terminal device sends the first UCI on the first PUCCH resource located on the SBFD symbol and / or the non-SBFD symbol. Thus, the terminal device can more reasonably select an uplink transmission resource, thereby improving the efficiency of uplink transmission.

Description

A communication method and related apparatus

[0001] This application claims priority to Chinese Patent Application No. 202411599254.X, filed on November 8, 2024, entitled "A Communication Method and Related Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communication technology, and in particular to a network configuration method and apparatus. Background Technology

[0003] In a Time Division Duplex (TDD) system, uplink transmission is not possible on downlink symbols. In contrast to TDD systems, Subband Full Duplex (SBFD) systems allocate uplink subband resources within downlink symbols, thereby increasing the available uplink resources.

[0004] The downlink symbols configured with uplink subband resources are called SBFD symbols. Terminal devices can send uplink signaling through the uplink subband resources of an SBFD symbol, and simultaneously receive downlink signaling through the downlink subband resources of the same SBFD symbol. Non-SBFD symbols, on the other hand, refer to those symbols that cannot be used for SBFD operations. Non-SBFD symbols typically follow the traditional TDD mode, where uplink and downlink data are transmitted separately in different time slots / symbols.

[0005] However, different terminal devices support different SBFD capabilities. Therefore, how terminal devices should choose to transmit on SBFD symbols or non-SBFD symbols is a problem that urgently needs to be solved. Summary of the Invention

[0006] This application provides a communication method and related apparatus for improving the efficiency of uplink transmission.

[0007] Firstly, this application provides a communication method that can be applied to a terminal side, such as a terminal device, a communication module / processing module in the terminal device, or a circuit or chip in the terminal device responsible for communication functions (such as a modem chip, also known as a baseband chip, or a system-on-chip (SoC) chip containing a modem core or a system-in-package (SIP) chip), or a circuit or chip in the terminal device responsible for processing functions (such as a graphics processing unit (GPU)). Taking the application of this method to a terminal device as an example, in this method, the terminal device receives a first message from a network device. The first message includes first configuration information and second configuration information. The first configuration information is used to indicate whether the configuration type of the transmission using the first physical uplink control channel (PUCCH) resource is a first configuration type or a second configuration type. The second configuration information indicates whether the symbol used to transmit the first downlink control information (UCI) is a sub-band full-duplex (SBFD) symbol or a non-SBFD symbol.

[0008] Transmissions using PUCCH resources corresponding to the first configuration type can be carried on SBFD symbols or non-SBFD symbols. In this application, when the first configuration information indicates that the configuration type of the transmission of the first PUCCH resource is the first configuration type, it means that the network device instructs the terminal device to send UCI only on the first PUCCH resource on SBFD symbols, or only on the first PUCCH resource on non-SBFD symbols. Transmissions using PUCCH resources corresponding to the second configuration type can be carried on both SBFD symbols and non-SBFD symbols. In this application, when the first configuration information indicates that the configuration type of the transmission of the first PUCCH resource is the second configuration type, it means that the network device instructs the terminal device to send UCI on the first PUCCH resource on both SBFD symbols and non-SBFD symbols.

[0009] After receiving the first configuration information and the second configuration information (i.e., the first message) from the network device, the terminal device sends the first UCI on the first PUCCH resource located on SBFD symbols and / or non-SBFD symbols based on the first and second configuration information. This allows the terminal device to select uplink transmission resources more rationally, improving uplink transmission efficiency.

[0010] As can be seen from the above, the first configuration information is used to indicate either a first configuration type or a second configuration type. Transmissions using PUCCH resources corresponding to the first configuration type can be carried on SBFD symbols or non-SBFD symbols. Transmissions using PUCCH resources corresponding to the second configuration type can be carried on both SBFD symbols and non-SBFD symbols. The second configuration information indicates whether the symbol used to transmit the first UCI is an SBFD symbol or a non-SBFD symbol. Therefore, in scenarios requiring periodic or semi-persistent transmission of the first UCI, both the first and second configuration information constrain whether the symbol used to transmit the first UCI is an SBFD symbol. In this application, the relationship between the first and second configuration information provides detailed standard specifications for terminal devices to select first PUCCH resources on SBFD symbols and / or non-SBFD symbols to transmit the first UCI. This ensures consistency between terminal devices and network devices regarding uplink transmission resources used to carry periodic or semi-persistent reporting, thereby improving the SBFD system design.

[0011] Based on the first aspect, in an optional implementation, if the first configuration information and the second configuration information satisfy the first condition, the first UCI is sent on the first PUCCH resource located on the SBFD symbol.

[0012] Based on the first aspect, in one optional implementation, the first condition includes one or more of the following:

[0013] Condition 1: The first configuration information indicates that the configuration type of the transmission performed by the first PUCCH resource is the first configuration type, and the second configuration information indicates that the symbol used to transmit the first UCI is an SBFD symbol. Specifically, since the transmission performed using the PUCCH resource corresponding to the first configuration type can be carried on either an SBFD symbol or a non-SBFD symbol, and the second configuration information indicates an SBFD symbol, the first and second configuration information can be combined. Therefore, the terminal device selects the first PUCCH resource located on the SBFD symbol to transmit the first UCI according to the indication of the second configuration information.

[0014] Condition 2: The first configuration information indicates that the configuration type for the transmission performed by the first PUCCH resource is the first configuration type, the second configuration information indicates that the symbol used to transmit the first UCI is an SBFD symbol, and the SBFD configuration of the first uplink portion bandwidth (BWP) corresponding to the first PUCCH resource is effective. Specifically, the terminal device needs to further determine whether the SBFD configuration of the uplink BWP corresponding to the first PUCCH resource is effective. When the SBFD configuration of the uplink BWP corresponding to the first PUCCH resource is effective, and the first and second configuration information can be combined, the terminal device selects the first PUCCH resource located on the SBFD symbol to transmit the first UCI.

[0015] Based on the first aspect, in one optional implementation, if the first configuration information and the second configuration information satisfy the second condition, the first UCI is sent on the first PUCCH resource located on a non-SBFD symbol.

[0016] Based on the first aspect, in one optional implementation, the second condition includes one or more of the following:

[0017] Condition 3: The first configuration information indicates that the configuration type of the transmission performed by the first PUCCH resource is the first configuration type, and the second configuration information indicates that the symbol used to transmit the first UCI is a non-SBFD symbol. Specifically, since the transmission performed using the PUCCH resource corresponding to the first configuration type can be carried on either SBFD symbols or non-SBFD symbols, and the second configuration information indicates a non-SBFD symbol, the first and second configuration information can be combined. Therefore, the terminal device selects the first PUCCH resource located on a non-SBFD symbol to transmit the first UCI according to the indication of the second configuration information.

[0018] Condition 4: The first configuration information indicates that the configuration type for the transmission performed by the first PUCCH resource is the first configuration type; the second configuration information indicates that the symbol used to transmit the first UCI is a non-SBFD symbol; and the SBFD configuration of the first uplink BWP corresponding to the first PUCCH resource is effective. Specifically, the SBFD configuration of the uplink BWP corresponding to the first PUCCH resource is effective, but since the first and second configuration information can be combined, and the second configuration information indicates a non-SBFD symbol, the terminal device selects the first PUCCH resource located on a non-SBFD symbol to transmit the first UCI according to the indication of the second configuration information.

[0019] Condition 5: The first configuration information indicates that the configuration type of the transmission performed by the first PUCCH resource is the first configuration type, the second configuration information indicates that the symbol used to transmit the first UCI is an SBFD symbol, and the SBFD configuration of the first uplink BWP corresponding to the first PUCCH resource is not effective. Specifically, since the transmission performed using the PUCCH resource corresponding to the first configuration type can be carried on either an SBFD symbol or a non-SBFD symbol, and the second configuration information indicates a non-SBFD symbol, the first and second configuration information can be combined. However, since the SBFD configuration of the first uplink BWP corresponding to the first PUCCH resource is not effective, an SBFD symbol cannot be configured in the first uplink BWP. Therefore, the terminal device cannot transmit the first UCI on the first PUCCH resource located on an SBFD symbol, and the terminal device can only transmit the first UCI on the first PUCCH resource located on a non-SBFD symbol.

[0020] Condition 6: The first configuration information indicates that the configuration type of the transmission performed by the first PUCCH resource is the first configuration type, the second configuration information indicates that the symbol used to transmit the first UCI is a non-SBFD symbol, and the SBFD configuration of the first uplink BWP corresponding to the first PUCCH resource is not effective. Specifically, since the transmission performed using the PUCCH resource corresponding to the first configuration type can be carried on either SBFD symbols or non-SBFD symbols, and the second configuration information indicates a non-SBFD symbol, the first and second configuration information can be combined. However, since the SBFD configuration of the first uplink BWP corresponding to the first PUCCH resource is not effective, SBFD symbols cannot be configured in the first uplink BWP. Therefore, the terminal device can only transmit the first UCI on the first PUCCH resource located on a non-SBFD symbol.

[0021] Condition 7: The first configuration information indicates that the configuration type for the transmission performed by the first PUCCH resource is the second configuration type, the second configuration information indicates that the symbol used for transmitting the first UCI is an SBFD symbol, and the SBFD configuration of the first uplink BWP corresponding to the first PUCCH resource is not effective. Specifically, since the transmission performed using the PUCCH resource corresponding to the second configuration type can be carried by both SBFD and non-SBFD symbols, although the second configuration information indicates that the symbol used for transmitting the first UCI is an SBFD symbol, the terminal device still takes precedence over the indication of the first configuration information. However, since the SBFD configuration of the first uplink BWP corresponding to the first PUCCH resource is not effective, an SBFD symbol cannot be configured in the first uplink BWP. Therefore, the terminal device cannot send the first UCI on the first PUCCH resource located on an SBFD symbol, and the terminal device can only send the first UCI on the first PUCCH resource located on a non-SBFD symbol.

[0022] Condition 8: The first configuration information indicates that the configuration type of the transmission performed by the first PUCCH resource is the second configuration type, the second configuration information indicates that the symbol used to transmit the first UCI is a non-SBFD symbol, and the SBFD configuration of the first uplink BWP corresponding to the first PUCCH resource is not effective. Specifically, since the transmission performed using the PUCCH resource corresponding to the second configuration type can be carried by both SBFD and non-SBFD symbols, although the second configuration information indicates that the symbol used to transmit the first UCI is a non-SBFD symbol, the terminal device still takes precedence over the indication of the first configuration information. However, since the SBFD configuration of the first uplink BWP corresponding to the first PUCCH resource is not effective, SBFD symbols cannot be configured in the first uplink BWP. Therefore, the terminal device cannot send the first UCI on the first PUCCH resource located on an SBFD symbol, and the terminal device can only send the first UCI on the first PUCCH resource located on a non-SBFD symbol.

[0023] Based on the first aspect, in an optional implementation, if the first configuration information and the second configuration information satisfy the third condition, the first UCI is transmitted on the first PUCCH resource located on the SBFD symbol and the non-SBFD symbol.

[0024] Based on the first aspect, in one optional implementation, the third condition includes one or more of the following:

[0025] Condition 9: The first configuration information indicates that the configuration type for the transmission performed on the first PUCCH resource is the second configuration type, and the second configuration information indicates that the symbol used for transmitting the first UCI is an SBFD symbol. Specifically, since the transmission performed on the PUCCH resource corresponding to the second configuration type can be carried on both SBFD and non-SBFD symbols, although the second configuration information indicates that the symbol used for transmitting the first UCI is an SBFD symbol, the terminal device still takes precedence over the indication of the first configuration information. Therefore, the terminal device ignores the second configuration information, or in other words, the second configuration information is ineffective. Thus, the terminal device transmits the first UCI on the first PUCCH resource located on both SBFD and non-SBFD symbols.

[0026] Condition 10: The first configuration information indicates that the configuration type of the transmission performed by the first PUCCH resource is the second configuration type, and the second configuration information indicates that the symbol used to transmit the first UCI is a non-SBFD symbol. Specifically, since the transmission performed using the PUCCH resource corresponding to the second configuration type can be carried on both SBFD and non-SBFD symbols, although the second configuration information indicates that the symbol used to transmit the first UCI is a non-SBFD symbol, the terminal device still takes precedence over the indication of the first configuration information. Therefore, the terminal device ignores the second configuration information, or in other words, the second configuration information is ineffective. Thus, the terminal device transmits the first UCI on the first PUCCH resource located on both SBFD and non-SBFD symbols.

[0027] Condition 11: The first configuration information indicates that the configuration type of the transmission performed by the first PUCCH resource is the second configuration type, the second configuration information indicates that the symbol used for transmitting the first UCI is an SBFD symbol, and the SBFD configuration of the first uplink portion bandwidth (BWP) corresponding to the first PUCCH resource is effective. Specifically, since the transmission performed using the PUCCH resource corresponding to the second configuration type can be carried on both SBFD and non-SBFD symbols, although the second configuration information indicates that the symbol used for transmitting the first UCI is an SBFD symbol, the terminal device still prioritizes the indication of the first configuration information, so the terminal device ignores the second configuration information, or in other words, the second configuration information is not effective. Furthermore, since the SBFD configuration of the first uplink portion bandwidth (BWP) corresponding to the first PUCCH resource is effective, SBFD symbols can be configured in the first uplink BWP. Therefore, the terminal device transmits the first UCI on the first PUCCH resource located on both SBFD and non-SBFD symbols.

[0028] Condition 12: The first configuration information indicates that the configuration type of the transmission performed by the first PUCCH resource is the second configuration type, the second configuration information indicates that the symbol used to transmit the first UCI is a non-SBFD symbol, and the SBFD configuration of the first uplink portion bandwidth (BWP) corresponding to the first PUCCH resource is effective. Specifically, since the transmission performed using the PUCCH resource corresponding to the second configuration type can be carried by both SBFD and non-SBFD symbols, although the second configuration information indicates that the symbol used to transmit the first UCI is a non-SBFD symbol, the terminal device still prioritizes the indication of the first configuration information, so the terminal device ignores the second configuration information, or in other words, the second configuration information is ineffective. Furthermore, since the SBFD configuration of the first uplink portion bandwidth (BWP) corresponding to the first PUCCH resource is effective, SBFD symbols can be configured in the first uplink BWP. Therefore, the terminal device transmits the first UCI on the first PUCCH resource located on both SBFD and non-SBFD symbols.

[0029] Based on the first aspect, in an optional implementation, the first message further includes third configuration information. That is, the network device sends the third configuration information to the terminal device, and correspondingly, the terminal device receives the third configuration information from the network device. This third configuration information is used to indicate whether the SBFD configuration of the first uplink BWP is effective.

[0030] Based on the first aspect, in one optional implementation, the terminal device determines whether the SBFD configuration of the first uplink BWP is effective based on the intersection between the frequency domain of the first uplink BWP and the uplink sub-band of the cell. The intersection between the frequency domain of the first uplink BWP and the uplink sub-band of the cell can be understood as: the entire frequency domain of the first uplink BWP is located within the range of the uplink sub-band of the cell; or, the entire uplink sub-band of the cell is located within the frequency domain of the first uplink BWP; or, the frequency domain of the first uplink BWP and the uplink sub-band of the cell partially overlap.

[0031] Based on the first aspect, in one optional implementation, the first UCI is a periodically reported or semi-persistently reported UCI. For example, the first UCI is Channel State Information (CSI), Scheduling Request (SR), or Hybrid Automatic Repeat reQuest Acknowledgement (HARQ-ACK) corresponding to a Semi-Persistent Scheduling (SPS) Physical Downlink Shared Channel (PDSCH).

[0032] Accordingly, when the first UCI is CSI, the second configuration information is one or more parameters in the CSI reporting configuration information; when the first UCI is SR, the second configuration information is one or more parameters in the SR configuration information; when the first UCI is HARQ-ACK corresponding to SPS-PDSCH, the second configuration information is one or more parameters in the SPS-PDSCH configuration information.

[0033] Based on the first aspect, in one optional implementation, the first UCI is the CSI corresponding to the first CSI reporting configuration. The second configuration information applies to all BWPs in the cell where the first CSI reporting configuration is located, that is, all BWPs in the cell where the first CSI reporting configuration is located use the same type of symbol (SBFD symbol or non-SBFD symbol) for CSI reporting. In other words, the valid symbol type (SBFD symbol or non-SBFD symbol) indicated in the second configuration information is applicable to the transmission of all PUCCH resources in the CSI reporting configuration information (pucch-CSI-ResourceList);

[0034] Alternatively, the second configuration information applies to one of the BWPs in the cell where the first CSI reporting configuration is located. That is, each BWP individually configures the valid symbol type for PUCCH resource transmission, and each BWP corresponds to one set of second configuration information. In other words, for each BWP in the pucch-CSI-ResourceList within a CSI reporting configuration (the first CSI reporting configuration), the valid symbol type for PUCCH resource transmission is configured separately. When multiple BWPs are configured in the first CSI reporting configuration, the second configuration information needs to be configured separately for each BWP.

[0035] Secondly, this application provides a communication method that can be applied to the terminal side, such as a terminal device, a communication module / processing module in the terminal device, or a circuit or chip in the terminal device responsible for communication functions (such as a modem chip, also known as a baseband chip, or a system-on-chip (SoC) chip containing a modem core or a system-in-package (SIP) chip), or a circuit or chip in the terminal device responsible for processing functions (such as a graphics processing unit (GPU)). Taking the application of this method to a terminal device as an example, in this method, the terminal device does not expect to receive second configuration information and first configuration information for indicating the second configuration type. The second configuration information indicates that the symbol used for transmitting the first UCI is a sub-band full-duplex SBFD symbol or a non-SBFD symbol. The transmission using the first PUCCH resource corresponding to the second configuration type can be carried by SBFD symbols and non-SBFD symbols.

[0036] Upon receiving a first message, which includes second configuration information and first configuration information indicating a first configuration type, transmissions using the first PUCCH resource corresponding to the first configuration type can be carried on SBFD symbols and non-SBFD symbols. This avoids situations where the first configuration information indicates uplink transmission can be carried on SBFD symbols and non-SBFD symbols, while the second configuration information indicates that the symbols used for uplink transmission are either SBFD symbols or non-SBFD symbols. This avoids conflicts between the first and second configuration information, ensuring consistency between terminal devices and network devices in the uplink transmission resources used for carrying periodic reporting, semi-persistent reporting, or repetitive transmissions, thus improving the SBFD system design.

[0037] Optionally, the phrase "the terminal device does not expect to receive the second configuration information and the first configuration information for indicating the second configuration type" can be replaced with other descriptions. For example, the terminal device does not expect to receive a combination of information such as the second configuration information and the first configuration information for indicating the second configuration type; or, the terminal device does not expect to receive both the second configuration information and the first configuration information for indicating the second configuration type; or, the network device does not send the second configuration information and the first configuration information for indicating the second configuration type to the terminal device; or, the terminal device expects to receive the second configuration information and the first configuration information for indicating the first configuration type; or, the network device sends the second configuration information and the first configuration information for indicating the first configuration type to the terminal device.

[0038] Optionally, if the terminal device still receives the second configuration information and the first configuration information indicating the second configuration type, the terminal device may ignore the first configuration information and / or the second configuration information.

[0039] Next, the terminal device transmits the first UCI on the first PUCCH resource located on the SBFD symbol and / or non-SBFD symbol, based on the first configuration information and the second configuration information. Specifically, the process by which the terminal device selects to transmit the first UCI on the SBFD symbol and / or non-SBFD symbol is similar to that described in conditions 1 to 6 above; please refer to the description of conditions 1 to 6 above for details.

[0040] Optionally, during the process of selecting to transmit the first UCI on an SBFD symbol and / or a non-SBFD symbol, the terminal device also needs to determine whether the SBFD configuration of the uplink BWP corresponding to the first PUCCH resource is effective. That is, the terminal device can only select to transmit the first UCI on the first PUCCH resource located on an SBFD symbol if the SBFD configuration of the uplink BWP corresponding to the first PUCCH resource is effective.

[0041] Since the terminal device does not expect to receive the second configuration information and the first configuration information used to indicate the second configuration type, conditions 7 to 12 will not be triggered in this scenario.

[0042] Based on the second aspect, in an optional implementation, if the terminal device receives first configuration information indicating the second configuration type after receiving second configuration information from the network device, the terminal device may ignore the first configuration information and / or the second configuration information.

[0043] Thirdly, this application provides a communication device, comprising:

[0044] The transceiver unit is used to receive a first message, which includes first configuration information and second configuration information. The first configuration information is used to indicate whether the configuration type of the transmission using the first physical uplink control channel (PUCCH) resource is a first configuration type or a second configuration type. The second configuration information indicates whether the symbol used to transmit the first uplink control information (UCI) is a sub-band full-duplex (SBFD) symbol or a non-SBFD symbol. The transmission using the PUCCH resource corresponding to the first configuration type can be carried on SBFD symbols or non-SBFD symbols, and the transmission using the PUCCH resource corresponding to the second configuration type can be carried on SBFD symbols and non-SBFD symbols.

[0086] The present application will now be described with reference to the accompanying drawings. The terminology used in the embodiments section is for illustrative purposes only and is not intended to limit the scope of the application. Those skilled in the art will recognize that, with technological advancements and the emergence of new scenarios, the technical solutions provided in this application are equally applicable to similar technical problems.

[0087] First, some of the nouns or terms used in this application will be explained, and these nouns or terms are also part of the content of the invention.

[0088] (1) The terms “system” and “network” in this application are used interchangeably. “Multiple” refers to two or more. “And / or” describes the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, or B exists alone, where A and B can be singular or plural. The character “ / ” generally indicates that the related objects before and after are in an “or” relationship. “At least one of the following” or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, “at least one of A, B and C” includes A, B, C, AB, AC, BC or ABC. Unless otherwise specified, the ordinal numbers such as “first” and “second” mentioned in this application are used to distinguish multiple objects and are not used to limit the order, sequence, priority or importance of multiple objects. Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0089] (2) In this application, “sending information” can be understood as one device sending information to another device, or it can also be understood as one logical module within a device sending information to another logical module. For example, “terminal device sending information” can be understood as a terminal device sending information to another device (such as a network device), or it can be understood as logical module 1 in the terminal device sending information to logical module 2 in the network device.

[0090] In this application, "receiving information" can be understood as one device receiving information from another device, or it can also be understood as a logical module within a device receiving information from another logical module. For example, "terminal device receiving information" can be understood as a terminal device receiving information from another device (such as a network device), or it can be understood as logical module 1 in the terminal device receiving information from logical module 2 in the network device.

[0091] In this application, "sending information to... (e.g., a network device)" or the relevant illustrations in the accompanying drawings can be understood as the destination of the information being a network device. This can include sending information directly or indirectly to a network device. "Receiving information from... (e.g., a network device)" or "receiving information from... (e.g., a network device)" or "receiving information sent (e.g., by a network device)" or the relevant illustrations in the accompanying drawings can be understood as the source of the information being a network device. This can include receiving information directly or indirectly from a network device. Information may undergo necessary processing between the source and destination, such as format changes, encoding, modulation, etc., but the destination can understand the valid information from the source. Similar expressions in this application can be understood in a similar way, and will not be elaborated further here.

[0092] (3) Configuration and Pre-configuration: In this application, both configuration and pre-configuration are used. Configuration refers to the network device or server sending configuration information or parameter values ​​to the terminal device via messages or signaling, so that the terminal device can determine the communication parameters or resources for transmission based on these values ​​or information. Pre-configuration is similar to configuration; it can be parameter information or parameter values ​​pre-negotiated between the network device / server and the terminal device, parameter information or parameter values ​​specified by standard protocols for use by the base station / network device or terminal device, or parameter information or parameter values ​​pre-stored in the base station / server or terminal device. This application does not limit this.

[0093] It should be understood that these values ​​and parameters can change or be updated.

[0094] (4) In this application, “instruction” may include direct instruction and indirect instruction, and may also include explicit instruction and implicit instruction. When a certain instruction information is used to instruct A, it can be understood that the instruction information carries A, directly instructs A, or indirectly instructs A.

[0095] In this application, the information indicated by the instruction information is called the information to be instructed. In specific implementations, there are many ways to indicate the information to be instructed, such as, but not limited to, directly indicating the information to be instructed, such as the information to be instructed itself or its index. It can also indirectly indicate the information to be instructed by indicating other information, where there is a relationship between the other information and the information to be instructed; or it can indicate only a part of the information to be instructed, while the other parts are known or pre-agreed upon, for example, by using a pre-agreed (e.g., protocol-predefined) arrangement of various information to indicate specific information, thereby reducing instruction overhead to some extent. This application does not limit the specific method of instruction. It is understood that for the sender of the instruction information, the instruction information can be used to indicate the information to be instructed, and for the receiver of the instruction information, the instruction information can be used to determine the information to be instructed.

[0096] Next, we will introduce the possible, non-limiting scenarios involved in this application.

[0097] New radio (NR) systems employ frequency division duplex (FDD), time division duplex (TDD), and subband full duplex (SBFD) mechanisms. These will be described below with reference to Figure 1. Figure 1 is a schematic diagram illustrating the implementation of the duplex mechanism.

[0098] FDD mechanism: Downlink transmission can be performed on the downlink bandwidth part (DL BWP) of slot 0, and uplink transmission can also be performed on the downlink bandwidth part (UL BWP) of the same slot 0. DL BWP and UL BWP are located on different carriers and are separate in the frequency domain.

[0099] TDD Mechanism: As shown in Figure 1, the DL BWP and UL BWP share the same center frequency. Their bandwidths can be the same or different. At any given time, the terminal device can only perform uplink or downlink transmission. For example, only downlink transmission is possible in slot 0, only uplink transmission in slot 4, and slot 3 is a flexible time slot, which can be used for either uplink or downlink transmission, but not simultaneously. The smallest granularity for uplink / downlink switching is the symbol. For instance, slot 3 is a flexible time slot consisting of 14 or 12 Orthogonal Frequency Division Multiplexing (OFDM) symbols. The first M symbols are downlink symbols, the last N symbols are uplink symbols, and the middle 14-MN (or 12-MN) symbols are flexible symbols. 0 <= M <= 14, 0 <= N <= 14, 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. The specific transmission direction is notified to the terminal device by the network device through Radio Resource Control (RRC) signaling or Downlink Control Information (DCI) scheduling.

[0100] Compared to the FDD mechanism, the TDD mechanism occupies less frequency domain resources. However, because uplink and downlink transmissions cannot be performed simultaneously in the TDD mechanism, uplink transmission delay will increase.

[0101] The SBFD mechanism can optimize the uplink latency issue of the TDD mechanism. The core idea of ​​SBFD is that uplink and downlink transmission resources can be configured simultaneously on a specific symbol or time slot in a TDD system. For example, as shown in Figure 1, within a time slot such as slot 0, there exists a frequency domain resource within the downlink BWP (Band of Resources). Uplink transmission can be performed on this frequency domain resource, thus reducing uplink latency. This frequency domain resource is usually called the uplink subband or uplink available physical resource block (PRB). Downlink transmission can also occur on slot 0. Network devices can perform uplink and downlink transmissions simultaneously on slot 0 (limited to the uplink or downlink subband). Terminal devices can also perform uplink and downlink transmissions simultaneously on slot 0 (i.e., full-duplex terminal devices), or they can perform only uplink or downlink transmissions (half-duplex terminal devices).

[0102] Compared to the TDD mechanism, the SBFD mechanism provides more uplink transmission resources, thereby reducing uplink transmission latency.

[0103] Specifically, in the SBFD system, network devices send TDD configuration information and SBFD configuration information to terminal devices.

[0104] TDD configuration information includes, but is not limited to, one or more of the following parameters: slot indices for downlink, uplink, and flexible slots; and symbol indices for uplink, downlink, and flexible symbols within flexible slots. Specifically, downlink symbols in downlink and flexible slots are used for downlink data transmission; uplink symbols in uplink and flexible slots are used for uplink data transmission; and flexible symbols in flexible slots can be used for both uplink and downlink data transmission.

[0105] SBFD configuration information includes, but is not limited to, one or more of the following parameters: SBFD slot / symbol position, and SBFD sub-band position within the SBFD slot. The SBFD slot / symbol position refers to some or all of the downlink slots / symbols or flexible slots / symbols configured in the TDD configuration, i.e., converting some or all downlink slots / symbols or flexible slots / symbols into SBFD symbols; the SBFD sub-band can be the frequency domain position of the uplink sub-band and / or the downlink sub-band.

[0106] The following section introduces the time-domain configuration method of the SBFD mechanism.

[0107] For terminal devices in RRC connected state, the base station can configure the time and frequency domain positions of the SBFD subband within a TDD carrier through RRC parameters.

[0108] Time-domain configuration method: As shown in Figure 2, the base station semi-statically configures the time-domain location of the SBFD subband using RRC parameters (e.g., TDD-UL-DL-Pattern). The base station configures DL symbols, UL symbols, and flexible symbols using the TDD-UL-DL-ConfigCommon parameter. SBFD symbols can be configured on DL symbols and / or flexible symbols. A configured SBFD symbol can start or end at any symbol within a slot. The time-domain period of the SBFD subband can be the same as the period configured in dl-UL-TransmissionPeriodicity in TDD-UL-DL-Pattern, or an integer multiple of the period configured in dl-UL-TransmissionPeriodicity in TDD-UL-DL-Pattern.

[0109] A time slot can contain SBFD symbols and non-SBFD symbols. Based on whether it contains SBFD symbols or non-SBFD symbols, time slots can be divided into three categories:

[0110] SBFD time slot: A time slot is an SBFD time slot if all symbols in it are SBFD symbols. For example, the third and fourth time slots in a TDD cycle (five time slots) in Figure 2 are SBFD time slots.

[0111] Non-SBFD time slots: If all symbols in a time slot are non-SBFD symbols, then the time slot is an SBFD time slot. For example, the first and fifth time slots within a TDD cycle in Figure 2 are non-SBFD time slots.

[0112] Hybrid time slot: A time slot that contains both SBFD symbols and non-SBFD symbols is called a hybrid time slot. For example, the second time slot within a TDD cycle in Figure 2 is a hybrid time slot.

[0113] Next, we will introduce the measurement of Channel State Information (CSI).

[0114] CSI measurements rely on Channel Status Information Reference Signal (CSI-RS) resources. CSI-RS resources can be Non-Zero Power (NZP) CSI-RS, CSI-Interference Measurement (IM), and CSI-Synchronization Signal and PBCH Block (SSB). NZP CSI-RS resources are used for channel or interference measurements, CSI-IM is used for interference measurements, and CSI-SSB is used to configure a set of SSB resources within a cell for SSB measurements.

[0115] The network configures CSI-RS resources as periodic, semi-persistent, or aperiodic through the higher-layer signaling resourceType in the CSI-RS resource configuration.

[0116] The periodic CSI-RS takes effect immediately after the RRC configuration signaling is issued. CSI measurement results will be reported periodically, with the reporting period configured by the RRC. The unit of the period can be a time slot.

[0117] Semi-persistent CSI-RS is activated by the base station after being configured via RRC configuration signaling. Once activated, CSI measurement results will be reported periodically until a deactivation signaling is received. The reporting period is configured by RRC, and the unit of the period can be a time slot.

[0118] Aperiodic CSI-RS is activated by the base station after being configured by RRC configuration signaling, and is only sent once after activation.

[0119] The time-frequency position of the CSI-RS in each time slot is configured by RRC. In terms of time, it can occupy 1, 2 or 4 OFDM symbols. In the frequency domain, the minimum is 24RB and the maximum is the entire Bandwidth Part (BWP). The allocation granularity is 4RB.

[0120] The network configures the reporting resources bound to the CSI reporting configuration to be periodic, semi-persistent, or aperiodic via the higher-level signaling reportConfigType in the CSI reporting configuration.

[0121] Among them, non-periodic CSI reporting is triggered by DCI, and PUSCH used to send non-periodic CSI is also triggered by DCI.

[0122] Semi-persistent CSI reporting can be triggered in the following two ways:

[0123] Triggering method 1: Triggered via MAC CE, the physical uplink control channel (PUCCH) used to send semi-persistent CSI is configured by RRC signaling;

[0124] Triggering method 2: Triggered via DCI. The physical uplink shared channel (PUSCH) used to send semi-persistent CSI is also triggered via DCI.

[0125] Periodic CSI reporting is configured by RRC signaling, and the PUCCH used to send periodic CSI is also configured by RRC signaling.

[0126] Both semi-persistent CSI and periodic CSI can be reported on the PUCCH, and their resource configuration is as follows:

[0127] Among the configuration parameters mentioned above, the PUCCH used for sending periodic CSI reports and semi-persistent CSI reports includes the following two parameters:

[0128] reportSlotConfig: Used to determine the time slot in which a periodically occurring PUCCH occurs by using the period (in time slots) and the time slot offset value within the period.

[0129] pucch-CSI-ResourceList: This is used to indicate the PUCCH resource ID. This resource ID corresponds to a PUCCH-resource IE in the PUCCH-Config Information Element (IE). The PUCCH-resource IE indicates the time-frequency resource location of the PUCCH, such as the OFDM symbol location (start symbol and number of symbols) of the PUCCH in a time slot, the PRB location, whether it is repeated, and other information.

[0130] `pucch-CSI-ResourceList` is a list, and `CSI-ReportConfig` is configured for a serving cell. This cell will further configure one or more Base Window Devices (BWPs). The PUCCH used to carry the CSI report is configured independently for each BWP. At any given time, only one BWP will be active in a cell, and the CSI report will be transmitted on the PUCCH corresponding to the active BWP.

[0131] As shown above, in a TDD system, uplink transmission is not possible on downlink symbols. Compared to a TDD system, an SBFD system adds uplink available resources, namely the uplink subband resources configured on downlink symbols. These resources can only be used for downlink transmission in a TDD system, but can be used for uplink transmission in an SBFD system. Therefore, for terminal devices supporting the SBFD mechanism, the available resources on SBFD symbols and non-SBFD symbols are different.

[0132] Currently, there are two configuration types for periodic transmission, semi-persistent transmission, or repetitive transmission in the SBFD mechanism.

[0133] First configuration type: The periodic, semi-persistent, or repetitive transmission is performed only on SBFD symbols, or the periodic, semi-persistent, or repetitive transmission is performed only on non-SBFD symbols;

[0134] Second configuration type: Periodic transmission, semi-persistent transmission, or repetitive transmission can be performed on SBFD symbols and non-SBFD symbols.

[0135] The base station can configure the terminal equipment to use either a first configuration type or a second configuration type for periodic or semi-persistent transmission via RRC configuration signaling. Specifically, the configuration granularity of this RRC configuration signaling can be divided into the following three configuration granularities:

[0136] Configuration granularity one: Configure either a first configuration type or a second configuration type for each terminal device in each serving cell. That is, configure the transmission configuration type of PUCCH resources for each terminal device in the cell separately. Therefore, on a single terminal device, the transmission configuration type of all PUCCH resources is the same. In this case, the configuration granularity of this RRC configuration signaling is at the terminal device level.

[0137] Configuration granularity two: Configure either a first configuration type or a second configuration type for each BWP of each terminal device. That is, configure the transmission configuration type of PUCCH resources for each BWP of the terminal device separately; therefore, the configuration types of each BWP of the terminal device can be different. In this case, the configuration granularity of the RRC signaling for the configuration type is at the BWP level.

[0138] Configuration granularity three: Configure either the first configuration type or the second configuration type for each serving cell. This means that the configuration type for PUCCH resource transmission is uniformly configured for all terminal devices within the cell. Specifically, the configuration type is the same across all terminal devices within the same cell, and on a single terminal device, the configuration type for all PUCCH resource transmissions is identical. In this case, the configuration granularity of the RRC configuration signaling is at the cell level.

[0139] On the other hand, when configuring granularity two, for each PUCCH resource, the PUCCH-Resource parameter corresponding to the PUCCH resource in the RRC configuration signaling can be used to configure the PUCCH resource as the first configuration type or the second configuration type; or, through the RRC configuration signaling, all PUCCH resources configured in PUCCH-Config can be uniformly configured to adopt the first configuration type or the second configuration type.

[0140] Although base stations can use RRC signaling to select a first configuration type or a second configuration type for terminal devices, thereby determining whether data transmission should occur on SBFD symbols and / or non-SBFD symbols, different terminal devices support varying SBFD capabilities. Therefore, determining how terminal devices should select between SBFD and non-SBFD symbols for transmission is a pressing issue that needs to be addressed.

[0141] To address the aforementioned problems, this application provides a communication method and related apparatus for improving uplink transmission efficiency. The communication method and related apparatus provided in this application can be applied to various communication systems. For example, 5th generation (5G) mobile communication systems, new radio (NR) systems, long term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, future communication systems, vehicle-to-everything (V2X) communication systems, device-to-device (D2D) communication systems, Internet of Things (IoT) communication systems, industrial internet communication systems, or satellite communication systems, etc. The wireless communication systems involved in this application also include, but are not limited to, narrowband Internet of Things (NB-IoT) systems.

[0142] For example, please refer to Figure 3, which is a possible, non-limiting system diagram of the communication method and related apparatus used in this application. As shown in Figure 3, the communication system 10 includes a radio access network (RAN) 100 and a core network (CN) 200. Optionally, the communication system 10 may also include an Internet 300. The RAN 100 includes at least one RAN node (110a and 110b in Figure 3, collectively referred to as 110) and at least one terminal device (120a-120j in Figure 3, collectively referred to as 120). The RAN 100 may also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in Figure 3). The terminal device 120 is wirelessly connected to the RAN node 110. The RAN node 110 is connected to the core network 200 wirelessly or via a wired connection. The core network equipment in core network 200 and RAN node 110 in RAN 100 can be different physical devices, or they can be the same physical device integrating core network logical functions and radio access network logical functions. Terminal devices and RAN nodes can be interconnected via wired or wireless means.

[0143] RAN 100 can be a cellular system related to the 3rd Generation Partnership Project (3GPP), such as a fourth-generation (4G) mobile communication system, a fifth-generation (5G) mobile communication system, or a future communication system. RAN 100 can also be an open RAN (O-RAN or ORAN), a cloud radio access network (CRAN), an evolved universal terrestrial radio access (E-UTRA) system, or a wireless fidelity (WiFi) system. RAN 100 can also be a communication system that integrates two or more of the above systems.

[0144] RAN node 110, sometimes also referred to as network equipment, access network equipment, RAN device, RAN entity, or access node, constitutes part of the communication system and is used to help terminal equipment achieve wireless access. Multiple RAN nodes 110 in communication system 10 can be of the same type or different types. In some scenarios, the roles of RAN node 110 and terminal equipment 120 are relative. For example, network element 120i in Figure 3 can be a helicopter or drone, which can be configured as a mobile base station. For terminal equipment 120j accessing RAN 100 through network element 120i, network element 120i is a base station; but for base station 110a, network element 120i is a terminal equipment. RAN node 110 and terminal equipment 120 are sometimes both referred to as communication devices. For example, network elements 110a and 110b in Figure 3 can be understood as communication devices with base station functions, and network elements 120a-120j can be understood as communication devices with terminal equipment functions.

[0145] In one possible scenario, RAN node 110 can be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next-generation NodeB (gNB), a base station in a future mobile communication system, or an access node in a WiFi system. Optionally, RAN node 110 can also be a macro base station (as shown in Figure 3, 110a), a micro base station or indoor station (as shown in Figure 3, 110b), a relay node or donor node, or a radio controller in a CRAN scenario. Optionally, RAN node 110 can also be a server, a wearable device, a vehicle, or in-vehicle equipment. For example, the access network equipment in vehicle-to-everything (V2X) technology can be a roadside unit (RSU). All or part of the functions of RAN node 110 in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (e.g., a cloud platform). The RAN node 110 may also be equipped with communication modules, circuits, or chips that perform corresponding communication functions. The RAN node 110 may also be configured with program instructions for performing corresponding communication functions, as well as corresponding program instructions. The RAN node 110 in this application may also be a logic node, logic module, or software capable of implementing all or part of the functions of the RAN node 110.

[0146] In another possible scenario, multiple RAN nodes collaborate to assist terminal devices in achieving wireless access, with different RAN nodes each implementing a portion of the base station's functions. For example, RAN nodes can be central units (CUs), distributed units (DUs), CU-control plane (CPs), CU-user plane (UPs), or radio units (RUs), etc. CUs and DUs can be set up separately or included in the same network element, such as a baseband unit (BBU). RUs can be included in radio frequency equipment or radio frequency units, such as remote radio units (RRUs), active antenna units (AAUs), or remote radio heads (RRHs).

[0147] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an ORAN system, CU can also be called O-CU (open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software and hardware modules.

[0148] Terminal equipment can be any device or module that connects to the communication system shown above and has corresponding communication functions. Terminal equipment can also be referred to as a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), fixed wireless access (FWA), or customer premises equipment (CPE), etc. Terminal equipment includes wireless communication functions (providing voice / data connectivity to users). Examples include handheld devices with wireless connectivity, in-vehicle devices, and machine-type communication (MTC) terminals. Currently, terminal devices can include: mobile phones, tablets, laptops, PDAs, mobile internet devices (MIDs), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in self-driving (e.g., drones, vehicles), wireless terminals in remote medical surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, and wireless terminals in smart homes. For example, wireless terminals in self-driving can be drones, helicopters, or airplanes. For example, wireless terminals in vehicle-to-everything (V2X) can be in-vehicle equipment, vehicle-mounted equipment, in-vehicle modules, vehicles, or ships. Wireless terminals in industrial control can be cameras, robots, or robotic arms. Wireless terminals in smart homes can be televisions, air conditioners, robot vacuums, speakers, or set-top boxes. Terminal devices typically contain communication modules, circuits, or chips that perform corresponding communication functions, and they also contain program instructions for performing those functions.

[0149] The communication method and related apparatus of this application will be further described below with reference to the accompanying drawings.

[0150] In this application, the RAN node shown in Figure 3 can be replaced with other terms, such as "network device". For ease of description, unless otherwise specified, "network device" will be used throughout this application. It should be understood that the technical solutions provided in this application are also applicable to other different expressions or types of "network devices" (e.g., base stations).

[0151] Please refer to Figure 4, which is a schematic diagram of a possible implementation of the communication method in this application. It should be understood that this application uses a terminal device and a network device as examples to illustrate the method, but this application does not limit the execution subject of the interaction. For example, the terminal device shown in Figure 4 can also be implemented as a chip, baseband chip, modem chip, system-on-chip (SoC) chip containing a modem core, system-in-package (SIP) chip, communication module, chip system, processor, logic module, or software within the terminal device; similarly, the network device shown in Figure 4 can also be implemented as a chip, baseband chip, modem chip, system-on-chip (SoC) chip containing a modem core, system-in-package (SIP) chip, communication module, chip system, processor, logic module, or software within the network device. In this application, when referring to a terminal device, it may refer to the terminal device itself, or to the chip, communication module, integrated circuit, processor, logic module, or software in the terminal device used to implement the communication method provided in this application, and this application does not make any specific limitation; when referring to a network device, it may refer to the network device itself, or to the chip, communication module, integrated circuit, processor, logic module, or software in the network device used to implement the communication method provided in this application, and this application does not make any specific limitation.

[0152] As shown in Figure 4, the communication method of this application includes, but is not limited to, steps 401 to 402.

[0153] 401. The network device sends a first message to the terminal device, and the terminal device receives the first message from the network device accordingly.

[0154] The first message includes first configuration information and second configuration information. The first configuration information is used to indicate whether the configuration type of the transmission using the first physical uplink control channel (PUCCH) resource is the first configuration type or the second configuration type. The second configuration information indicates whether the symbol used to transmit the first uplink control information (UCI) is a sub-band full-duplex SBFD symbol or a non-SBFD symbol.

[0155] The first configuration information and the second configuration information in this application will be described below.

[0156] Regarding the first configuration information:

[0157] Transmissions using PUCCH resources corresponding to the first configuration type can be carried on SBFD symbols or non-SBFD symbols. In this application, when the first configuration information indicates that the configuration type for the transmission of the first PUCCH resource is the first configuration type, it means that the network device instructs the terminal device to send UCI only on the first PUCCH resource on SBFD symbols, or only on the first PUCCH resource on non-SBFD symbols.

[0158] Transmissions using PUCCH resources corresponding to the second configuration type can be carried on both SBFD symbols and non-SBFD symbols. In this application, when the first configuration information indicates that the transmission configuration type of the first PUCCH resource is the second configuration type, it means that the network device instructs the terminal device to send UCIs on the first PUCCH resources on both SBFD symbols and non-SBFD symbols.

[0159] For example, the first configuration information can specifically be one or more parameters in the PUCCH resource configuration information. The first PUCCH resource is the PUCCH resource configured by the first configuration information for periodic, semi-persistent, or repetitive transmission. As can be seen from the above, network devices can configure terminal devices to use either the first configuration type or the second configuration type for periodic, semi-persistent, or repetitive transmission via RRC configuration signaling. Specifically, the first configuration information can be used to configure the transmission of all PUCCH resources corresponding to the terminal device (equivalent to configuration granularity one or configuration granularity three above), meaning that the transmission configuration type of all PUCCH resources on the terminal device is the same, i.e., all are configured as either the first or second configuration type. At this point, the first PUCCH resource is all the PUCCH resources of the terminal device; or, the first configuration information can be used to configure the transmission of all PUCCH resources corresponding to one BWP of the terminal device (equivalent to configuration granularity two above). That is, on this terminal device, for the transmission of all PUCCH resources corresponding to different BWPs (equivalent to configuration granularity two above), the configuration type can be the same or different. In this case, the first PUCCH resource is the PUCCH resource corresponding to one of the BWPs of the terminal device. In configuration granularity two, for each PUCCH resource, the PUCCH-Resource parameter corresponding to that PUCCH resource in the RRC configuration signaling can be further configured as either the first configuration type or the second configuration type. That is, on this terminal device, for different PUCCH resources, the configuration type can be the same or different. Alternatively, when configuring at granularity two, RRC configuration signaling can be used to uniformly configure all PUCCH resources configured in PUCCH-Config using either the first configuration type or the second configuration type. That is, on the terminal device, all PUCCH resources configured in the same PUCCH-Config have the same configuration type; for PUCCH resources configured in different PUCCH-Configs, the configuration type can be the same or different.

[0160] Optionally, the network device also sends TDD configuration information to the terminal device, and correspondingly, the terminal device also receives TDD configuration information from the network device. For example, the TDD configuration information includes, but is not limited to, one or more of the following parameters: slot indices for downlink slots, uplink slots, and flexible slots; and symbol indices for uplink symbols, downlink symbols, and flexible symbols in the flexible slots. Specifically, downlink symbols in downlink slots and flexible slots are used for downlink data transmission; uplink symbols in uplink slots and flexible slots are used for uplink data transmission; and flexible symbols in flexible slots can be used for both uplink and downlink data transmission.

[0161] Optionally, the network device also sends SBFD configuration information to the terminal device, and correspondingly, the terminal device also receives SBFD configuration information from the network device. For example, the SBFD configuration information includes, but is not limited to, one or more of the following parameters: SBFD slot / symbol position, and SBFD sub-band position within the SBFD slot. The SBFD slot / symbol position refers to some or all of the downlink slots / symbols or flexible slots / symbols configured in the TDD configuration, i.e., converting some or all of the downlink slots / symbols or flexible slots / symbols into SBFD symbols; the SBFD sub-band can be the frequency domain position of the uplink sub-band and / or the downlink sub-band.

[0162] Regarding the second configuration information:

[0163] The second configuration information indicates whether the symbol used to transmit the first UCI is an SBFD symbol or a non-SBFD symbol. In this application, the first UCI is a periodically reported or semi-persistently reported UCI. For example, the first UCI is Channel State Information (CSI), Scheduling Request (SR), or Hybrid Automatic Repeat reQuest Acknowledgement (HARQ-ACK) corresponding to a Semi-Persistent Scheduling (SPS) Physical Downlink Shared Channel (PDSCH).

[0164] Accordingly, when the first UCI is CSI, the second configuration information is one or more parameters in the CSI reporting configuration information; when the first UCI is SR, the second configuration information is one or more parameters in the SR configuration information; when the first UCI is HARQ-ACK corresponding to SPS-PDSCH, the second configuration information is one or more parameters in the SPS-PDSCH configuration information.

[0165] In one possible implementation, the first UCI is the CSI corresponding to the first CSI reporting configuration. The second configuration information applies to all BWPs in the cell where the first CSI reporting configuration is located; that is, all BWPs in the cell where the first CSI reporting configuration is located use the same type of symbol (SBFD symbol or non-SBFD symbol) for CSI reporting. In other words, the valid symbol type (SBFD symbol or non-SBFD symbol) indicated in the second configuration information applies to the transmission of all PUCCH resources in the CSI reporting configuration information (pucch-CSI-ResourceList).

[0166] Alternatively, the second configuration information applies to one of the BWPs in the cell where the first CSI reporting configuration is located. That is, each BWP individually configures the valid symbol type for PUCCH resource transmission, and each BWP corresponds to one set of second configuration information. In other words, for each BWP in the pucch-CSI-ResourceList within a CSI reporting configuration (the first CSI reporting configuration), the valid symbol type for PUCCH resource transmission is configured separately. When multiple BWPs are configured in the first CSI reporting configuration, the second configuration information needs to be configured separately for each BWP.

[0167] Optionally, the first configuration information can be carried in RRC signaling; optionally, the second configuration information can be carried in RRC signaling.

[0168] Optionally, the first configuration information and the second configuration information can be carried in the same RRC signaling, that is, the first configuration information and the second configuration information are different information elements (IEs) in the same RRC signaling.

[0169] Optionally, the first configuration information and the second configuration information can be carried in different RRC signaling messages. For example, the terminal device first receives the first configuration information from the network device, and then receives the second configuration information from the network device; or, the terminal device first receives the second configuration information from the network device, and then receives the first configuration information from the network device.

[0170] 402. The terminal device transmits a first UCI on a first PUCCH resource located on an SBFD symbol and / or a non-SBFD symbol based on the first configuration information and the second configuration information.

[0171] After receiving the first configuration information and the second configuration information (i.e., the first message) from the network device, the terminal device sends the first UCI on the first PUCCH resource located on SBFD symbols and / or non-SBFD symbols based on the first and second configuration information. This allows the terminal device to select uplink transmission resources more rationally, improving uplink transmission efficiency.

[0172] As shown above, the first configuration information indicates either a first configuration type or a second configuration type. Transmissions using the PUCCH resources corresponding to the first configuration type can be carried on SBFD symbols or non-SBFD symbols. Transmissions using the PUCCH resources corresponding to the second configuration type can be carried on both SBFD symbols and non-SBFD symbols. The second configuration information indicates whether the symbol used to transmit the first UCI is an SBFD symbol or a non-SBFD symbol. Therefore, in scenarios where the first UCI needs to be transmitted periodically, semi-persistently, or repeatedly, both the first and second configuration information constrain whether the symbol used to transmit the first UCI is an SBFD symbol. Thus, how the terminal device selects to transmit the first UCI on SBFD symbols and / or non-SBFD symbols when faced with the indications of the first and second configuration information is a problem that urgently needs to be solved. In this application, a detailed standard specification is provided for the relationship between the first configuration information and the second configuration information, so that the terminal device can select the first PUCCH resource on the SBFD symbol and / or non-SBFD symbol to send the first UCI. This enables the terminal device and the network device to maintain consistency in the uplink transmission resources used to carry periodic or semi-persistent reporting, thereby improving the SBFD system design.

[0173] The following sections will introduce the various specifications provided in this application regarding how to select to send the first UCI on SBFD symbols and / or non-SBFD symbols.

[0174] In one possible implementation, if the first configuration information and the second configuration information satisfy a first condition, a first UCI is transmitted on the first PUCCH resource located on the SBFD symbol. The first condition includes one or more of the following:

[0175] Condition 1: The first configuration information indicates that the configuration type of the transmission performed by the first PUCCH resource is the first configuration type, and the second configuration information indicates that the symbol used to transmit the first UCI is an SBFD symbol. Specifically, since the transmission performed using the PUCCH resource corresponding to the first configuration type can be carried on either an SBFD symbol or a non-SBFD symbol, and the second configuration information indicates an SBFD symbol, the first and second configuration information can be combined. Therefore, the terminal device selects the first PUCCH resource located on the SBFD symbol to transmit the first UCI according to the indication of the second configuration information.

[0176] Condition 2: The first configuration information indicates that the configuration type for the transmission performed by the first PUCCH resource is the first configuration type, the second configuration information indicates that the symbol used to transmit the first UCI is an SBFD symbol, and the SBFD configuration of the first uplink portion bandwidth (BWP) corresponding to the first PUCCH resource is effective. Specifically, the terminal device needs to further determine whether the SBFD configuration of the uplink BWP corresponding to the first PUCCH resource is effective. When the SBFD configuration of the uplink BWP corresponding to the first PUCCH resource is effective, and the first and second configuration information can be combined, the terminal device selects the first PUCCH resource located on the SBFD symbol to transmit the first UCI.

[0177] In one possible implementation, if the first configuration information and the second configuration information satisfy a second condition, a first UCI is transmitted on a first PUCCH resource located on a non-SBFD symbol. The second condition includes one or more of the following:

[0178] Condition 3: The first configuration information indicates that the configuration type of the transmission performed by the first PUCCH resource is the first configuration type, and the second configuration information indicates that the symbol used to transmit the first UCI is a non-SBFD symbol. Specifically, since the transmission performed using the PUCCH resource corresponding to the first configuration type can be carried on either SBFD symbols or non-SBFD symbols, and the second configuration information indicates a non-SBFD symbol, the first and second configuration information can be combined. Therefore, the terminal device selects the first PUCCH resource located on a non-SBFD symbol to transmit the first UCI according to the indication of the second configuration information.

[0179] Condition 4: The first configuration information indicates that the configuration type for the transmission performed by the first PUCCH resource is the first configuration type; the second configuration information indicates that the symbol used to transmit the first UCI is a non-SBFD symbol; and the SBFD configuration of the first uplink BWP corresponding to the first PUCCH resource is effective. Specifically, the SBFD configuration of the uplink BWP corresponding to the first PUCCH resource is effective, but since the first and second configuration information can be combined, and the second configuration information indicates a non-SBFD symbol, the terminal device selects the first PUCCH resource located on a non-SBFD symbol to transmit the first UCI according to the indication of the second configuration information.

[0180] Condition 5: The first configuration information indicates that the configuration type of the transmission performed by the first PUCCH resource is the first configuration type, the second configuration information indicates that the symbol used to transmit the first UCI is an SBFD symbol, and the SBFD configuration of the first uplink BWP corresponding to the first PUCCH resource is not effective. Specifically, since the transmission performed using the PUCCH resource corresponding to the first configuration type can be carried on either an SBFD symbol or a non-SBFD symbol, and the second configuration information indicates a non-SBFD symbol, the first and second configuration information can be combined. However, since the SBFD configuration of the first uplink BWP corresponding to the first PUCCH resource is not effective, an SBFD symbol cannot be configured in the first uplink BWP. Therefore, the terminal device cannot transmit the first UCI on the first PUCCH resource located on an SBFD symbol, and the terminal device can only transmit the first UCI on the first PUCCH resource located on a non-SBFD symbol.

[0181] Condition 6: The first configuration information indicates that the configuration type of the transmission performed by the first PUCCH resource is the first configuration type, the second configuration information indicates that the symbol used to transmit the first UCI is a non-SBFD symbol, and the SBFD configuration of the first uplink BWP corresponding to the first PUCCH resource is not effective. Specifically, since the transmission performed using the PUCCH resource corresponding to the first configuration type can be carried on either SBFD symbols or non-SBFD symbols, and the second configuration information indicates a non-SBFD symbol, the first and second configuration information can be combined. However, since the SBFD configuration of the first uplink BWP corresponding to the first PUCCH resource is not effective, SBFD symbols cannot be configured in the first uplink BWP. Therefore, the terminal device can only transmit the first UCI on the first PUCCH resource located on a non-SBFD symbol.

[0182] Condition 7: The first configuration information indicates that the configuration type for the transmission performed by the first PUCCH resource is the second configuration type, the second configuration information indicates that the symbol used for transmitting the first UCI is an SBFD symbol, and the SBFD configuration of the first uplink BWP corresponding to the first PUCCH resource is not effective. Specifically, since the transmission performed using the PUCCH resource corresponding to the second configuration type can be carried by both SBFD and non-SBFD symbols, although the second configuration information indicates that the symbol used for transmitting the first UCI is an SBFD symbol, the terminal device still takes precedence over the indication of the first configuration information. However, since the SBFD configuration of the first uplink BWP corresponding to the first PUCCH resource is not effective, an SBFD symbol cannot be configured in the first uplink BWP. Therefore, the terminal device cannot send the first UCI on the first PUCCH resource located on an SBFD symbol, and the terminal device can only send the first UCI on the first PUCCH resource located on a non-SBFD symbol.

[0183] Condition 8: The first configuration information indicates that the configuration type of the transmission performed by the first PUCCH resource is the second configuration type, the second configuration information indicates that the symbol used to transmit the first UCI is a non-SBFD symbol, and the SBFD configuration of the first uplink BWP corresponding to the first PUCCH resource is not effective. Specifically, since the transmission performed using the PUCCH resource corresponding to the second configuration type can be carried by both SBFD and non-SBFD symbols, although the second configuration information indicates that the symbol used to transmit the first UCI is a non-SBFD symbol, the terminal device still takes precedence over the indication of the first configuration information. However, since the SBFD configuration of the first uplink BWP corresponding to the first PUCCH resource is not effective, SBFD symbols cannot be configured in the first uplink BWP. Therefore, the terminal device cannot send the first UCI on the first PUCCH resource located on an SBFD symbol, and the terminal device can only send the first UCI on the first PUCCH resource located on a non-SBFD symbol.

[0184] In one possible implementation, if the first configuration information and the second configuration information satisfy a third condition, a first UCI is transmitted on a first PUCCH resource located on an SBFD symbol and a non-SBFD symbol. The third condition includes one or more of the following:

[0185] Condition 9: The first configuration information indicates that the configuration type for the transmission performed on the first PUCCH resource is the second configuration type, and the second configuration information indicates that the symbol used for transmitting the first UCI is an SBFD symbol. Specifically, since the transmission performed on the PUCCH resource corresponding to the second configuration type can be carried on both SBFD and non-SBFD symbols, although the second configuration information indicates that the symbol used for transmitting the first UCI is an SBFD symbol, the terminal device still takes precedence over the indication of the first configuration information. Therefore, the terminal device ignores the second configuration information, or in other words, the second configuration information is ineffective. Thus, the terminal device transmits the first UCI on the first PUCCH resource located on both SBFD and non-SBFD symbols.

[0186] Condition 10: The first configuration information indicates that the configuration type of the transmission performed by the first PUCCH resource is the second configuration type, and the second configuration information indicates that the symbol used to transmit the first UCI is a non-SBFD symbol. Specifically, since the transmission performed using the PUCCH resource corresponding to the second configuration type can be carried on both SBFD and non-SBFD symbols, although the second configuration information indicates that the symbol used to transmit the first UCI is a non-SBFD symbol, the terminal device still takes precedence over the indication of the first configuration information. Therefore, the terminal device ignores the second configuration information, or in other words, the second configuration information is ineffective. Thus, the terminal device transmits the first UCI on the first PUCCH resource located on both SBFD and non-SBFD symbols.

[0187] Condition 11: The first configuration information indicates that the configuration type of the transmission performed by the first PUCCH resource is the second configuration type, the second configuration information indicates that the symbol used for transmitting the first UCI is an SBFD symbol, and the SBFD configuration of the first uplink portion bandwidth (BWP) corresponding to the first PUCCH resource is effective. Specifically, since the transmission performed using the PUCCH resource corresponding to the second configuration type can be carried on both SBFD and non-SBFD symbols, although the second configuration information indicates that the symbol used for transmitting the first UCI is an SBFD symbol, the terminal device still prioritizes the indication of the first configuration information, so the terminal device ignores the second configuration information, or in other words, the second configuration information is not effective. Furthermore, since the SBFD configuration of the first uplink portion bandwidth (BWP) corresponding to the first PUCCH resource is effective, SBFD symbols can be configured in the first uplink BWP. Therefore, the terminal device transmits the first UCI on the first PUCCH resource located on both SBFD and non-SBFD symbols.

[0188] Condition 12: The first configuration information indicates that the configuration type of the transmission performed by the first PUCCH resource is the second configuration type, the second configuration information indicates that the symbol used to transmit the first UCI is a non-SBFD symbol, and the SBFD configuration of the first uplink portion bandwidth (BWP) corresponding to the first PUCCH resource is effective. Specifically, since the transmission performed using the PUCCH resource corresponding to the second configuration type can be carried by both SBFD and non-SBFD symbols, although the second configuration information indicates that the symbol used to transmit the first UCI is a non-SBFD symbol, the terminal device still prioritizes the indication of the first configuration information, so the terminal device ignores the second configuration information, or in other words, the second configuration information is ineffective. Furthermore, since the SBFD configuration of the first uplink portion bandwidth (BWP) corresponding to the first PUCCH resource is effective, SBFD symbols can be configured in the first uplink BWP. Therefore, the terminal device transmits the first UCI on the first PUCCH resource located on both SBFD and non-SBFD symbols.

[0189] Optionally, the terminal device can determine whether the SBFD configuration of the first uplink BWP is effective in several ways.

[0190] Method 1: The first message also includes third configuration information. That is, the network device sends third configuration information to the terminal device, and the terminal device receives the third configuration information from the network device. This third configuration information is used to indicate whether the SBFD configuration of the first uplink BWP is effective.

[0191] Method 2: The terminal device determines whether the SBFD configuration of the first uplink BWP is effective based on the intersection between the frequency domain of the first uplink BWP and the uplink sub-band of the cell. The intersection between the frequency domain of the first uplink BWP and the uplink sub-band of the cell can be understood as: the entire frequency domain of the first uplink BWP is within the range of the uplink sub-band of the cell; or, the entire uplink sub-band of the cell is within the frequency domain of the first uplink BWP; or, the frequency domain of the first uplink BWP and the uplink sub-band of the cell partially overlap.

[0192] If the intersection between the frequency domain of the first uplink BWP and the uplink subband of the cell is greater than or equal to a preset threshold, the terminal device determines that the SBFD configuration of the first uplink partial bandwidth BWP has taken effect.

[0193] If the intersection between the frequency domain of the first uplink BWP and the uplink subband of the cell is less than a preset threshold, the terminal device determines that the SBFD configuration of the first uplink portion bandwidth BWP is not effective.

[0194] In this application, "greater than" can specifically mean "higher than", and "less than" can specifically mean "lower than". Furthermore, "greater than" in the examples can be replaced with "greater than or equal to", and "less than" can be replaced with "less than or equal to", without any specific limitation in this application. It should be understood that the examples provided in this application are merely illustrative and do not constitute a limitation on this application. Optionally, the preset threshold value is greater than or equal to 0 resource blocks (RBs).

[0195] In summary, after the terminal device receives the first configuration information and the second configuration information, provided that the SBFD configuration of the first uplink bandwidth (BWP) corresponding to the first PUCCH resource is effective, the terminal device will prioritize the first configuration information. Therefore, if the first configuration information indicates that the configuration type for transmission using the first PUCCH resource is the second configuration type, then regardless of whether the second configuration information indicates that the symbol used for transmitting the first UCI is an SBFD symbol or a non-SBFD symbol, the terminal device will transmit the first UCI on the first PUCCH resource located on both SBFD and non-SBFD symbols, as indicated by the first configuration information. If the first configuration information indicates that the configuration type for transmission using the first PUCCH resource is the first configuration type, then the terminal device will transmit the first UCI on the first PUCCH resource located on either SBFD or non-SBFD symbols, as indicated by the second configuration information. In other words, the second configuration information will only take effect if the configuration type for transmission using the first PUCCH resource is the first configuration type.

[0196] Conversely, when the terminal device receives the first configuration information and the second configuration information, if the SBFD configuration of the first uplink bandwidth BWP corresponding to the first PUCCH resource is not effective, the terminal device can only send the first UCI on the first PUCCH resource located on a non-SBFD symbol.

[0197] On the other hand, this application provides another communication method. In this communication method, the terminal device does not expect to receive second configuration information and first configuration information indicating the second configuration type. The second configuration information indicates that the symbol used to transmit the first UCI is a sub-band full-duplex SBFD symbol or a non-SBFD symbol. The transmission using the first PUCCH resource corresponding to the second configuration type can be carried on SBFD symbols and non-SBFD symbols.

[0198] Upon receiving a first message, which includes second configuration information and first configuration information indicating a first configuration type, transmissions using the first PUCCH resource corresponding to the first configuration type can be carried on SBFD symbols and non-SBFD symbols. This avoids situations where the first configuration information indicates uplink transmission can be carried on SBFD symbols and non-SBFD symbols, while the second configuration information indicates that the symbols used for uplink transmission are either SBFD symbols or non-SBFD symbols. This avoids conflicts between the first and second configuration information, ensuring consistency between terminal devices and network devices regarding uplink transmission resources used for carrying periodic or semi-persistent reporting, thus improving the SBFD system design.

[0199] Optionally, the phrase "the terminal device does not expect to receive the second configuration information and the first configuration information for indicating the second configuration type" can be replaced with other descriptions. For example, the terminal device does not expect to receive a combination of information such as the second configuration information and the first configuration information for indicating the second configuration type; or, the terminal device does not expect to receive both the second configuration information and the first configuration information for indicating the second configuration type; or, the network device does not send the second configuration information and the first configuration information for indicating the second configuration type to the terminal device; or, the terminal device expects to receive the second configuration information and the first configuration information for indicating the first configuration type; or, the network device sends the second configuration information and the first configuration information for indicating the first configuration type to the terminal device.

[0200] Optionally, if the terminal device still receives the second configuration information and the first configuration information indicating the second configuration type, the terminal device may ignore the first configuration information and / or the second configuration information.

[0201] Next, the terminal device transmits the first UCI on the first PUCCH resource located on the SBFD symbol and / or non-SBFD symbol, based on the first configuration information and the second configuration information. Specifically, the process by which the terminal device selects to transmit the first UCI on the SBFD symbol and / or non-SBFD symbol is similar to that described in conditions 1 to 6 above; please refer to the description of conditions 1 to 6 above for details.

[0202] Optionally, during the process of selecting to transmit the first UCI on an SBFD symbol and / or a non-SBFD symbol, the terminal device also needs to determine whether the SBFD configuration of the uplink BWP corresponding to the first PUCCH resource is effective. That is, the terminal device can only select to transmit the first UCI on the first PUCCH resource located on an SBFD symbol if the SBFD configuration of the uplink BWP corresponding to the first PUCCH resource is effective.

[0203] Since the terminal device does not expect to receive the second configuration information and the first configuration information used to indicate the second configuration type, conditions 7 to 12 will not be triggered in this scenario.

[0204] Accordingly, this application also provides related apparatus for implementing the above-described solutions. Please refer to Figure 5, which is a schematic diagram of a communication device 500 provided in an embodiment of this application. This communication device 500 can realize the functions of the terminal device in the above method embodiments, and therefore can also achieve the beneficial effects of the above method embodiments. In this application embodiment, the communication device 500 can be a terminal device, or an integrated circuit or component inside the terminal device, such as a chip, baseband chip, modem chip, SoC chip containing a modem core, system-in-package (SIP) chip, communication module, chip system, processor, etc.

[0205] As shown in Figure 5, the communication device 500 includes a transceiver unit 501 and a processing unit 502. Optionally, the transceiver unit 501 may include a transmitting unit and a receiving unit, which are used to perform transmitting and receiving, respectively.

[0206] The transceiver unit 501 is used to receive a first message, which includes first configuration information and second configuration information. The first configuration information is used to indicate whether the configuration type of the transmission using the first physical uplink control channel (PUCCH) resource is a first configuration type or a second configuration type. The second configuration information indicates whether the symbol used to transmit the first uplink control information (UCI) is a sub-band full-duplex (SBFD) symbol or a non-SBFD symbol. The transmission using the PUCCH resource corresponding to the first configuration type can be carried on SBFD symbols or non-SBFD symbols, and the transmission using the PUCCH resource corresponding to the second configuration type can be carried on SBFD symbols and non-SBFD symbols.

[0207] The transceiver unit 501 is also configured to transmit a first UCI on a first PUCCH resource located on an SBFD symbol and / or a non-SBFD based on the first configuration information and the second configuration information.

[0208] In one possible design, the processing unit 502 is used to determine that the SBFD configuration of the first uplink partial bandwidth BWP has taken effect when the intersection between the frequency domain of the first uplink BWP and the uplink subband of the cell is greater than or equal to a preset threshold.

[0209] The processing unit 502 is further configured to determine that the SBFD configuration of the first uplink partial bandwidth BWP is not effective if the intersection between the frequency domain of the first uplink BWP and the uplink subband of the cell is less than a preset threshold.

[0210] It should be noted that the information interaction and execution process between the modules / units in the communication device 500 are based on the same concept as the method embodiment corresponding to Figure 4 in this application.

[0217] Please refer to Figure 7, which is a schematic diagram of the structure of the communication device involved in the above embodiments provided in the embodiments of this application.

[0218] It is understood that the communication device 700 includes, for example, modules, units, elements, circuits, or interfaces, which are appropriately configured together to execute the technical solutions provided in this application.
