Description

Uplink transmission method and communication device Technical Field The present application relates to the field of communications, and more particularly, to a method for uplink transmission and a communication apparatus. Background With the rapid development of New Radio (NR) in the fifth generation mobile communication technology, various communication requirements are presented, and in order to meet the requirements of the emerging services, a scheme of sub-band full duplex (subband-overlapping full duplex, SBFD) is proposed to promote the uplink coverage of the time division duplex (time division duplex, TDD) system. Sub-band full duplex refers to that in a TDD system, a network device can receive and transmit on one time slot or one orthogonal frequency division multiplexing (orthogonal frequency division multiplexing, OFDM) symbol by using different sub-bands for uplink transmission and downlink transmission. However, if Physical Uplink SHARED CHANNEL (PUSCH) transmission is performed on SBFD symbols (the frequency domain resources on SBFD symbols include uplink subbands and downlink subbands) and uplink symbols, since the frequency domain resources available for PUSCH transmission on uplink symbols are different from the frequency domain resources available for PUSCH transmission on SBFD symbols, the frequency domain resources occupied by PUSCH transmission configured by the base station may not be within the frequency domain resources available for PUSCH transmission on SBFD symbols. Disclosure of Invention The application provides an uplink transmission method and a communication device, which can ensure that the frequency domain resources occupied by SBFD symbols in PUSCH transmission cannot exceed the uplink sub-band range. In a first aspect, a method for uplink transmission is provided. The method can be applied to a terminal device side, such as a terminal device or a communication module in the terminal device, or a circuit or a chip (such as a modem (modem) chip, also called a baseband (baseband) chip, or a system on chip (SoC) chip or a system in package (SYSTEMIN PACKAGE, SIP) chip) containing a modem core, which is responsible for communication functions in the terminal device. The method is described by taking the application of the method to terminal equipment as an example. The method comprises the steps of receiving first information, wherein the first information is used for indicating first frequency domain resources, the first frequency domain resources comprise M resource block groups (resource block group, RBGs), M is a positive integer, determining second frequency domain resources according to the first frequency domain resources, the second frequency domain resources comprise M RBGs, the first RBGs included in the second frequency domain resources are determined based on the first RBGs included in the first frequency domain resources, if M is larger than 1, the first frequency domain interval is the same as the second frequency domain interval, the first frequency domain interval is the interval between the M-th RBGs included in the first frequency domain resources and the m+1th RBGs, the second frequency domain interval is the interval between the M-th RBGs included in the second frequency domain resources and the m+1th RBGs, m=1, 2, M-1, the first frequency domain resources are frequency domain resources of a first PUSCH on a non-SBFD time unit, and the second frequency domain resources are frequency domain resources of the first PUSCH on a SBFD time unit. Based on the above technical solution, in the case that the network device only indicates the first frequency domain resource of the first PUSCH on the non-SBFD time unit, the terminal device may determine the second frequency domain resource of the first PUSCH on the SBFD time unit according to the first frequency domain resource, instead of using the first frequency domain resource as the frequency domain resource of the first PUSCH on the SBFD time unit, so that it may be avoided that the first frequency domain resource indicated by the network device is not within the frequency domain resource range available for the first PUSCH transmission on the SBFD time unit, and the terminal device cannot transmit the first PUSCH on the SBFD time unit. In addition, the network device can indicate that the first frequency domain resource includes M RBGs by using the RBGs as granularity through the first information, so that the network device is beneficial to flexibly configuring continuous frequency domain resources or discontinuous frequency domain resources to the terminal device. With reference to the first aspect, in certain implementations of the first aspect, the first information further indicates a first frequency domain offset value, or the method further includes receiving second information, the second information being used to indicate the first frequency domain offset value. Optionally, the first RBG included in the s
