HYBRID SECTOR SELECTION AND BEAMFORMING
An example method may include configuring a pattern of a sounding packet of a first wireless node in a resource space. Configuring the pattern may include assigning first precoders to a first subset of the resource space for a first antenna sector of the first wireless node; and assigning second precoders to a second subset of the resource space for a second antenna sector of the first wireless node. The method may include wirelessly transmitting the sounding packet with the configured pattern to a second wireless node. The method may include transmitting data packets from the first wireless node to the second wireless node according to one or more transmission parameters that are at least one of received from the second wireless node or determined based on channel state information (CSI) feedback received from the second wireless node.
1 . A method, comprising:
generating at least one of channel state information (CSI) and one or more transmission parameters based on a sounding packet, the one or more transmission parameters including at least one of transmit antenna state and a beamforming matrix, wherein the sounding packet comprises:
multiple pluralities of precoders associated with subsets of a resource space, wherein a given plurality of the multiple pluralities of precoders is received at a wireless node from a particular antenna sector of a sender node; and
sending at least one of the one or more transmission parameters and CSI feedback that includes or is derived from the CSI.
