1. A wireless communication method, comprising:
performing, by a user device, a random access preamble transmission to a network node;
transmitting, by the user device, a response message to the network node, wherein the response message carries link recovery indication information indicating the user device is performing a link recovery procedure;
monitoring, by the user device, a downlink control information with a cyclic redundancy check (CRC) scrambled by a first type of radio network temporary identifier; and
performing, by the user device after detecting the downlink control information with the CRC scrambled by the first type of radio network temporary identifier, a transmission to the network node on a channel of a same cell as a cell of the random access preamble transmission using a same spatial filter as that for the random access preamble transmission and a power that is determined based on an index of 0 for a target power in a target power set, a path loss estimation associated with a reference signal of an index qnew, and a closed loop power control having a value of 0.
