Classification: CPC H  B | IPC B  H

Claim 0:
1. 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:
request a non-precoded sounding reference signal (SRS) from one or more served user equipments (UEs) at one or more intervals;
determine a channel estimate to each of the one or more served UEs using the non-precoded SRS received from the one or more served UEs;
compute multiple input, multiple output (MIMO) configuration information for the base station based on one or more of the channel estimate and a running average of interference covariance, Rnn, from the one or more served UEs;
perform an enhanced clear channel assessment (eCCA) using a first random contention window value, wherein the eCCA is performed on a shared communication channel;
transmit a spatial channel reservation signal on the shared communication channel to at least one of the one or more served UEs in response to success of the eCCA, wherein the spatial channel reservation signal identifies the MIMO configuration information, including at least a transmit beamforming (TxBF) directional parameter; and
transmit data on the shared communication channel to the at least one of the one or more served UEs in response to a spatial channel reservation response signal received from the at least one of the one or more served UEs.
