A method and a device in a node used for wireless communication are disclosed in the present disclosure. A first node transmits a first Random-Access (RA) Preamble and a first radio signal, the first RA Preamble being associated with the first radio signal, the first RA Preamble being transmitted on a Physical Uplink Shared Channel (PUSCH), and a first bit block being used for generating the first radio signal; receives Physical Downlink Control Channel PDCCH, the PDCCH comprising a first information block; and transmits a second RA Preamble and a second radio signal, the second RA Preamble being associated with the second radio signal, and the second RA Preamble being transmitted on a PUSCH, the first bit block being used for generating the second radio signal; the RA channels being Physical Random Access Channel (PRACH) occasions.

Method and device in a node used for wireless communication

Example systems and methods are provided for maintaining a system clock during a sleep mode of a mobile communication device. An example system may include a high frequency clock circuit configured to generate a system clock, and a low frequency clock circuit configured to generate a sleep clock, where the sleep clock has a lower frequency than the system clock. The example system may further include a sleep system configured to deactivate the system clock in response to the mobile communication device entering sleep mode. The sleep system may include a sleep counter configured to use the sleep clock to maintain a sleep count for the deactivated system clock during the sleep mode, and a calibration unit configured to activate a calibration clock at periodic intervals during the sleep mode and utilize the calibration clock to calibrate a frequency of the sleep clock.
