1. A method for communication, comprising:
obtaining information that influences selecting a random access (RA) mode between a plurality of RA modes of a terminal device, the information indicating at least one of the following:
a status of a channel between the terminal device and a network device for performing RA,
a capability of the terminal device for performing random access, or
a predefined access category of the terminal device;
selecting a RA mode between the plurality of RA modes at least in part based on the obtained information; and
performing RA to the network device with the selected RA mode, wherein obtaining the information indicating the status of the channel comprises:
monitoring a power level of the channel, and wherein the method further comprises in response to a determination that the power level is below a power threshold, determining that the channel is idle, and selecting a quick random access mode, or in response to a determination that the power level is above a power threshold, determining that the channel is busy, and selecting a slow random access mode.
