摘要： A method and apparatus for an access point (AP) accessing a channel occupied by a neighboring AP within clear channel assessment (CCA) range. The method is implemented by setting a transmit null towards the neighboring AP, while acquiring accurate channel knowledge with minimal bandwidth penalty to surrounding networks, via a combination of sparse explicit sounding, and a following implicit channel estimation of the neighboring APs for updating the explicit data achieved by the sparse explicit sounding. An AP implementing the method is also disclosed.

摘要： A communication device operating in time division duplex (TDD) mode using multiple antennas is provided herein. The communication device uses receive channel estimation measurements to perform transmit beamforming and multiple input multiple output (MIMO) transmission, based on self-calibration of the various up/down paths via a method of transmission and reception between its own antennas, thus achieving reciprocity mapping between up and down links. Either user equipment (UE) or a base station may routinely perform this self-calibration to obtain the most current correction factor for the channel reciprocity to reflect the most current operating conditions present during TDD MIMO operation.

摘要： A system having a multi-layer (multi-stream) multiple-input-multiple-output (MIMO) receiving system, having a MIMO baseband module and a radio distribution network (RDN) connected to the MIMO receiving system. The RDN has two or more beamformers that are fed by two or more antennas, so that a total number of antennas in the system are greater than the number of branches of the MIMO baseband module. Each of the beamformers combines RF signals coming from the antennas. The system further implements an antenna routing module that swaps antennas between different beamformers according to one or more qualitative indicators derived from the baseband module, thus increasing the probability of grouping antennas that have lower conflicts between best phases of different layers' transmitted signals. The system increases the range of antenna selection beyond the set of antennas available for each beamformer.
