Random access resource allocation for integrated access and backhaul nodes

A method for wireless communications, comprising:

• receiving, by a second communication node from a first communication node, a first set of parameters related to random access procedure, wherein the random access procedure is performed by the second communication node on a first communication link between the first communication node and the second communication node;
• and
• transmitting, by the second communication node, a random access signal that uses the first set of parameters on the first communication link;
• wherein the first communication link shares at least some transmission resources with a second communication link between the first communication node and a third communication node;
• and
• wherein the first set of parameters include random access time-frequency resources;
• and
• wherein time domain resources of transmission resources are independently configured for the second communication node and the third communication node.

A wireless communications apparatus comprising a processor, wherein the processor is configured to:

• configure a first set of parameters related to random access procedure, wherein the random access procedure is performed by a second communication node on a first communication link between a first communication node and the second communication node;
• and
• receive, from the second communication node, a random access signal that uses the first set of parameters on the first communication link;
• wherein a second communication link between the first communication node and a third communication node shares at least some transmission resources with the first communication link;
• wherein the first set of parameters include random access time-frequency resources;
• and
• wherein time domain resources of transmission resources are independently configured for the second communication node and the third communication node.
