1. A method for wireless communication, comprising:
generating, by a terminal device, a first type of signaling that comprises an index corresponding to a resource selected from a set of resources for a reference signal;
transmitting, by the terminal device, the first type of signaling over a random access channel to a base station, wherein the first type of signaling initiates a beam link recovery procedure;
assuming, by the terminal device, a Quasi Co-Location (QCL) relation between (1) the resource and a downlink control channel, and (2) the resource and a downlink data channel;
receiving, by the terminal device from the base station, a second type of signaling carried in the downlink control channel using the QCL relation between the resource and the downlink control channel, wherein the second type of signaling notifies that the base station has received the first type of signaling from the terminal device, the second type of signaling further comprising an identification of the terminal device; and
receiving, by the terminal device from the base station, a data transmission carried in the downlink data channel according to the QCL relation between the resource and the downlink data channel.
