Abstract: This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, for managing high volumes of space-time-streams in Wi-Fi systems. An access point (AP) may transmit packets including long training field (LTF) sections using a number of space-time-streams greater than eight. Mobile stations (STAs) in the system may or may not be capable of processing this number of streams. The AP may modulate an LTF section using a matrix with dimensions smaller than the number of streams by using tone-interleaving or by performing modulation with separate matrices in time and frequency. In some other implementations, the AP may split the antennas for transmission into groups, each group transmitting either different packets in a subset of streams or a same packet in a subset of tones. In further implementations, the AP may combine multiple space-time-streams into a super stream that supports reception at different types of STAs.

Abstract: Aspects are provided which handle dynamic blockage of beams transmitted by a base station to UEs in millimeter wave communication. In one aspect, the base station identifies at least two UEs with which the base station has established a link and which may be potentially blocked from the base station by a dynamic blocker such as a moving vehicle. After the potentially blocked UEs are identified, the base station schedules all identified UEs for joint beam training and receives feedback transmitted by the UEs to determine if a dynamically blocked spatial region exists. If a blockage exists, the base station performs a follow-up procedure to avoid the dynamically blocked spatial region and provide coverage for the UEs, for example, by blanking out or not using blocked beams in subsequent beam training and/or by coordinating with a neighbor cell. The base station may thus proactively improve coverage of dynamically blocked UEs.

The sector scheduler causes data to be transmitted to the UE via one or more transmit antennas of the first antenna array and at least one transmit antenna associated with a second antenna array of a selected adjacent sector based on the number of transmit antennas of the first antenna array being less than the maximum MIMO capability of the UE.
