Description

Communication method and related device Technical Field The present application relates to the field of communications technologies, and in particular, to a communications method and a related device. Background In a time division duplex (Time Division Duplex, TDD) system, uplink transmission is not possible on the downlink symbol. The subband full duplex (subband full duplex, SBFD) system configures uplink subband resources in the downlink symbols by the SBFD system relative to the TDD system, thereby increasing the uplink available resources. The downlink symbol configured with the uplink subband resource is SBFD symbols. The terminal device may send uplink signaling through uplink subband resources in SBFD symbols, and may also receive downlink signaling through downlink subband resources in SBFD symbols. Whereas non-SBFD symbols refer to those symbols that are not available for SBFD operation, non-SBFD symbols typically follow a conventional TDD mode, i.e., uplink and downlink data are transmitted on different time slots/symbols, respectively. However, SBFD capabilities supported by different terminal devices are also different. Therefore, how to select to transmit on SBFD symbols or SBFD symbols is a current problem to be solved. Disclosure of Invention The application provides a communication method and a related device, which are used for improving the uplink transmission efficiency. In a first aspect, the present application provides a communication method, which may be applied to a terminal side, for example, a terminal device, a communication module/processing module in the terminal device, or a circuit or a chip in the terminal device that is responsible for a communication function (such as a modem (modem) chip, also called a baseband (baseband) chip, or a system on chip (SoC) chip or a system in package (SYSTEM IN PACKAGE) SIP chip that includes a modem core), or a circuit or a chip in the terminal device that is responsible for a processing function (such as a graphics processor (graphics processing unit, GPU)). Taking the example that the method is applied to the terminal equipment, in the method, the terminal equipment receives a first message from the network equipment, wherein the first message comprises first configuration information and second configuration information, the first configuration information is used for indicating that the configuration type of transmission using the first physical uplink control channel (physical uplink control channel, PUCCH) resource is the first configuration type or the second configuration type, and the second configuration information is used for indicating that the symbol used for transmitting the first uplink control information (Downlink Control Information, UCI) is a sub-band full duplex SBFD symbol or a non-SBFD symbol. The transmission performed by using the PUCCH resource corresponding to the first configuration type may be carried in SBFD symbols or non-SBFD symbols. In the present 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 indicates that the network device instructs the terminal device to send UCI only on the first PUCCH resource on SBFD symbols or send UCI only on the first PUCCH resource on non-SBFD symbols. Transmissions using PUCCH resources corresponding to the second configuration type may be carried over SBFD symbols and non-SBFD symbols. In the application, when the first configuration information indicates that the configuration type of the transmission of the first PUCCH resource is the second configuration type, the network equipment indicates that the terminal equipment can send UCI on the first PUCCH resource with SBFD symbols and the first PUCCH resource with non-SBFD symbols. After receiving the first configuration information and the second configuration information (i.e., the first message) from the network device, the terminal device transmits a first UCI based on the first configuration information and the second configuration information on a first PUCCH resource located on SBFD symbols and/or non-SBFD symbols. Therefore, the terminal equipment can select uplink transmission resources more reasonably, and the efficiency of uplink transmission is improved. As can be seen from the above, the first configuration information is used to indicate the first configuration type or the second configuration type. The transmission performed by using the PUCCH resource corresponding to the first configuration type may be carried in SBFD symbols or non-SBFD symbols. Transmissions using PUCCH resources corresponding to the second configuration type may be carried over SBFD symbols and non-SBFD symbols. The second configuration information indicates whether the symbol used to transmit the first UCI is SBFD symbols or non-SBFD symbols. It can be seen that, in a scenario where periodic or semi-persistent tra
