IPC: H04W74/00
Filed: 2018-05-08
Abstract: Embodiments of the present disclosure relate to a method, device and computer readable storage media for monitoring a RA procedure. In example embodiments, a method implemented at a terminal device is provided. According to the method, a timer is started to monitor selection of a RA resource in response to a RA procedure for accessing a network device being initiated. The timer is configured with expiration time. The timer is stopped in response to a RA resource being selected for transmitting a RA preamble to the network device. A preamble transmission counter is incremented in response to the timer expiring. The preamble transmission counter records the number of transmitted RA preambles. A failure of the RA procedure is indicated in response to the incremented preamble transmission counter exceeding a predetermined threshold. Embodiments of the present disclosure enable completion of the RA procedure regardless of out of coverage situation where no beam is available to be selected for transmitting a RA preamble.
