Abstract
Provided are a random access method and device, which may reduce the latency of a terminal device in a random access process and improve the reliability of a first message (MSG) in the random access process. The method includes that: in response to a terminal device initiating random access to a base station of a target cell and the random access is successful, and the terminal device sends first information to the base station of the target cell, the first information including at least one of an Uplink (UL) Timing Advance (TA) and a parameter related to transmission power for a preamble.
Claims19
A method for communication, comprising:
- in response to a terminal device initiating random access to a base station of a target cell and the random access being successful, sending, by the terminal device, first information to the base station of the target cell, the first information comprising a parameter related to transmission power for a preamble,
- identification information of the target cell and
- a beam index used by the terminal device.
A method for communication, comprising:
- acquiring, by a base station of a target cell, first information, the first information comprising a parameter related to transmission power for a preamble, identification information of the target cell and a beam index used by the terminal device;
- and
- updating or configuring, by the base station of the target cell, configuration information related to the transmission power for the preamble during the random access according to the first information.
A terminal device, comprising a transceiver, wherein the transceiver is configured to:
- in response to a terminal device initiating random access to a base station of a target cell and the random access being successful,
- send first information to the base station of the target cell, the first information comprising a parameter related to transmission power for a preamble, identification information of the target cell and a beam index used by the terminal device.
