Claim 27:
28. The UE of claim 27,
wherein MIMO configuration information includes one or more of:
a MIMO rank;
a number of transmit antennas;
a number of receive antennas;
the TxBF directional parameter; and
the RxBF directional parameter,

wherein the configuration of the at least one processor to perform the CCA includes configuration of the at least one processor to:
compute an effective interference to one or more neighboring receiver nodes using at least the TxBF directional parameter and MIMO rank of the MIMO configuration information;
compare the effective interference with a default power detection threshold, wherein the effective interference being within the default power detection threshold identifies the success of the CCA; and
refrain from transmission of the spatial channel reservation response signal in response to the effective interference exceeding the default power detection threshold, and

wherein the RxBF directional parameter is identified by the spatial channel reservation signal via one of:
the RxBF directional parameter and MIMO rank embedded into a payload of the spatial channel reservation signal; or
the spatial channel reservation signal precoded using the RxBF directional parameter and MIMO rank.
