Claim 17:
18. A base station configured for wireless communication, the base station comprising:
at least one processor; and
a memory coupled to the at least one processor,
wherein the at least one processor is configured to:
compute multiple input, multiple output (MIMO) configuration information for a shared communication channel between the base station and at least one user equipment (UE) scheduled for uplink transmissions, wherein the MIMO configuration information is based one or more of a channel estimate and a current interference covariance, Rnn, from the at least one UE;
perform an enhanced clear channel assessment (eCCA) using a first random contention window value, wherein the eCCA is performed on the shared communication channel;
transmit a spatial channel reservation signal on the shared communication channel to a first UE of the at least one UE in response to success of the eCCA, wherein the spatial channel reservation signal identifies the MIMO configuration information, including at least a receive beamforming (RxBF) directional parameter; and

receive the uplink transmissions from the first UE on the shared communication channel in response to a spatial channel reservation response signal received from the first UE.
