1. A communication method, applied to a first communication node, comprising:
in response to a condition being satisfied, determining a quasi co-location reference signal of a first quasi co-location type associated with an activated transmission configuration indication (TCI) state, the activated TCI state having a minimum TCI state identifier, wherein the condition comprises:
the first communication node is not provided with spatial relationship information of an uplink signal, and
a serving cell where the uplink signal is located is not configured with a control resource set (CORESET);
determining information of the uplink signal according to the quasi co-location reference signal; and
communicating with a second communication node based on the information,
wherein the determining the information of the uplink signal comprises:
determining a pathloss reference signal of the uplink signal according to the quasi co-location reference signal.
