Abstract: A method, device and computer readable medium for determining TA. A method includes, the network device (120) determines an estimation of a timing advance and an error of the timing advance based on a random access preamble received from the terminal device (110). The network device (120) determines different communication modes with different lengths of overheads for the terminal device (110) based on the error. The network device (120) may update the estimation of the timing advance based on feedback information from the terminal device (110). In this way, accuracy of the estimation of the timing advancing is improved.

Abstract: The method implemented at a network device includes dividing a wireless system bandwidth into a plurality of non-overlapping bandwidth ranges each including a plurality of operating channels available for channel bonding. The method also includes allocating one of the plurality of bandwidth ranges for a wireless communication between the network device and a terminal device served by the network device. The method further includes determining, from the plurality of operating channels for the bandwidth range, one operating channel as a primary channel of the wireless communication. Embodiments of the present disclosure also provide a corresponding network device, a method implemented at a terminal device and a corresponding terminal device, and a non-transitory computer-readable medium.
