1. A first node, comprising:
at least one processor; and
one or more non-transitory computer-readable storage media coupled to the at least one processor and storing programming instructions for execution by the at least one processor, wherein the programming instructions, when executed, cause the first node to perform operations comprising:
transmitting a first plurality of random access preambles by using a first spatial filter, wherein a first plurality of physical random access channel occasions are used for transmission of the first plurality of random access preambles;
monitoring a first control signaling during a first time window in response to the transmitting of the first plurality of random access preambles;
transmitting a second plurality of random access preambles by using a second spatial filter, wherein a second plurality of physical random access channel occasions are used for transmission of the second plurality of random access preambles; and
monitoring a second control signaling during a second time window in response to the transmitting of the second plurality of random access preambles;
wherein a length of the first time window is the same as a length of the second time window, and a first quantity of the first plurality of random access preambles is different than a second quantity of the second plurality of random access preambles, wherein the length of the first time window is one of a plurality of candidate time lengths, and a number of the first plurality of random access preambles is one of a plurality of candidate numbers, wherein the plurality of candidate numbers corresponds to a same candidate time length of the plurality of candidate time lengths.
