Abstract: A wireless communication method includes configuring, by a first communication node, a first set of parameters related to random access procedure by a second communication node on a first communication link between the first communication node and the second communication node, and receiving, from the second communication node, a random access signal that uses the first set of parameters on the first communication link. The first communication node also provides wireless connectivity to a third communication node via a second communication link that shares at least some transmission resources with the first communication link. The first set of parameters includes one or more of a random access format, a random access sequence index set, a random access sequence root sequence index, a random access cyclic shift, and random access time-frequency resources.
