A method for wireless communications, comprising: detecting , by a first wireless node, during a first portion of a first discovery opportunity, at least one directional preamble sent by a second wireless node via a transmit beam, wherein the first discovery opportunity comprises a first plurality of symbols and the first portion is allocated for transmission of directional preambles and comprises a first set of symbols of the first plurality of symbols; sending , by the first wireless node, during a second portion of the first discovery opportunity, a beam response to the second wireless node to indicate the detection of the directional preamble during the first portion of the first discovery opportunity, wherein: the second portion is allocated for transmission of a beam response and comprises a second set of symbols of the first plurality of symbols, the first discovery opportunity comprises a third portion, including a third set of symbols of the first plurality of symbols, between the first portion and the second portion, and the third portion is allocated for transmission of peer discovery messages corresponding to a discovery opportunity prior to the first discovery opportunity; and monitoring , by the first wireless node, during a second discovery opportunity after the first discovery opportunity, for a peer discovery message indicating receipt of the beam response by the second wireless node, wherein the second discovery opportunity comprises a second plurality of symbols. detecting , by a first wireless node, during a first portion of a first discovery opportunity, at least one directional preamble sent by a second wireless node via a transmit beam, wherein the first discovery opportunity comprises a first plurality of symbols and the first portion is allocated for transmission of directional preambles and comprises a first set of symbols of the first plurality of symbols; sending , by the first wireless node, during a second portion of the first discovery opportunity, a beam response to the second wireless node to indicate the detection of the directional preamble during the first portion of the first discovery opportunity, wherein: the second portion is allocated for transmission of a beam response and comprises a second set of symbols of the first plurality of symbols, the first discovery opportunity comprises a third portion, including a third set of symbols of the first plurality of symbols, between the first portion and the second portion, and the third portion is allocated for transmission of peer discovery messages corresponding to a discovery opportunity prior to the first discovery opportunity; and monitoring , by the first wireless node, during a second discovery opportunity after the first discovery opportunity, for a peer discovery message indicating receipt of the beam response by the second wireless node, wherein the second discovery opportunity comprises a second plurality of symbols. the second portion is allocated for transmission of a beam response and comprises a second set of symbols of the first plurality of symbols, the first discovery opportunity comprises a third portion, including a third set of symbols of the first plurality of symbols, between the first portion and the second portion, and the third portion is allocated for transmission of peer discovery messages corresponding to a discovery opportunity prior to the first discovery opportunity; and monitoring , by the first wireless node, during a second discovery opportunity after the first discovery opportunity, for a peer discovery message indicating receipt of the beam response by the second wireless node, wherein the second discovery opportunity comprises a second plurality of symbols. <EOS>
