Transmission method and apparatus thereof

A terminal device, comprising a processor and a transceiver, wherein

• the processor is configured to perform idle state sensing on one or more candidate transmission frequency domain resources, wherein the one or more candidate transmission frequency domain resources are configured for physical uplink control channel (PUCCH) information transmission, wherein the one or more candidate transmission frequency domain resources are determined based on PUCCH resource configuration information that includes an identifier mapped to m bandwidth parts of n available bandwidth parts within a period of time, wherein the m bandwidth parts are selectively activated by a network device to be used as the one or more candidate transmission frequency domain resources for the terminal device to perform uplink transmissions, wherein m is greater than 1, m is less than n, and m and n are both positive integer values;
• the processor is further configured to determine, based on a sensing result of the candidate transmission frequency domain resources, a transmission frequency domain resource from the one or more candidate transmission frequency domain resources for PUCCH information transmission, wherein, in response to sensing that at least two candidate transmission frequency domain resources from the one or more candidate transmission frequency domain resources are in an idle state, the processor is configured to select one candidate transmission frequency domain resource from the at least two candidate transmission frequency domain resources based on an identifier of the terminal device, and determine the selected candidate transmission frequency domain resource as a transmission domain resource for PUCCH information transmission;
• and
• the transceiver is configured to transmit the PUCCH information by using the determined transmission frequency domain resource.

A non-transitory machine-readable medium having instructions stored therein, which when executed by a processor of a terminal device, cause the processor to perform operations, the operations comprising:

• performing idle state sensing on one or more candidate transmission frequency domain resources, wherein the one or more candidate transmission frequency domain resources are configured for physical uplink control channel (PUCCH) information transmission on a physical uplink control channel, wherein the one or more candidate transmission frequency domain resources are determined based on PUCCH resource configuration information that includes an identifier mapped to m bandwidth parts of n available bandwidth parts within a period of time, wherein the m bandwidth parts are selectively activated by a network device to be used as the one or more candidate transmission frequency domain resources for the terminal device to perform uplink transmissions, wherein m is greater than 1, m is less than n, and m and n are both positive integer values;
• determining, based on a sensing result of the one or more candidate transmission frequency domain resources, a transmission frequency domain resource from the one or more candidate transmission frequency domain resources for PUCCH information transmission, comprising:
• in response to sensing that at least two candidate transmission frequency domain resources from the one or more candidate transmission frequency domain resources are in an idle state, selecting, by the terminal device, one candidate transmission frequency domain resource from the at least two candidate transmission frequency domain resources based on an identifier of the terminal device, and determining the selected candidate transmission frequency domain resource as a transmission domain resource for PUCCH information transmission;
• and
• transmitting the PUCCH information by using the determined transmission frequency domain resource.
