A communication system that includes a management server communicatively coupled to a gNB and a plurality of remote antenna arrays distributed spatially over a geographical area. The management server causes each remote antenna array of the plurality of remote antenna arrays to obtain one or more signal synchronization block (SSB) signals in a mmWave frequency band from the gNB via a dedicated communication medium. Each remote antenna array of the plurality of remote antenna arrays obtains different SSB signals via the dedicated communication medium. The management server further causes each remote antenna array of the plurality of remote antenna arrays to execute beamforming to direct one or more beams of RF signals corresponding to the obtained one or more SSB signals to serve its corresponding UEs.

The present invention provides methods and apparatus for implementing spatial multiplexing in conjunction with the one or more multiple access protocols during the broadcast of information in a wireless network. One example includes transmitting a first and a second data signal to a remote unit from a respective first and a second spatially separate antenna of a base station so that the first and second data signals have a first spatial configuration, determining that the first and the second data signals are not spatially separated by the remote unit, reconfiguring the (spatial multiplexing logic) spatial configuration of the first and second data signals to a second spatial configuration, and transmitting a third and fourth data signal to the remote unit from a second different antenna configuration according to the second spatial configuration.

The present disclosure is directed to a system and method for selecting a sub-group of user terminals (UTs) among a group of UTs served by a sector of a cellular network to schedule independent data streams for transmission to over the same time-frequency interval. In one embodiment, the sub-group of UTs is selected to limit inter-user interference among the sub-group of UTs. In another embodiment, the sub-group of UTs is selected to limit inter-user interference experienced by a UT that is at or near the boundary of the sector that serves the sub-group of UTs.

A wireless communications system is presented that adapts its mode of operation between spatial and non-spatial multiplexing in response to transmission-specific variables. Mode determination logic determines, in response to a received signal, if spatial or non-spatial multiplexing should be used to transmit a subscriber datastream between the BTS and the UE. The mode determination logic receives a measure of a transmission characteristic of the signal, compares the transmission characteristic to a transmission characteristic threshold and selects either spatial or non-spatial multiplexing in response to the comparison. The transmission characteristic includes at least one of delay spread, post-processing signal-to-noise ratio, CRC failure, residual inter-symbol interference, mean square error, coherence time, and path loss.

Mitigating wireless networking problems of a wireless network

The present disclosure is directed to a system and method for determining an EIRP constraint for a data stream based on the direction that a beam carrying the data stream is to be radiated by an array of antennas rather than using a fixed EIRP constraint for all such beams. The system and method can use the direction the beam is to be radiated to determine a distance between the array of antennas and the closest point (or location) in which a human being can potentially be impacted by the radiated beam. For larger distances, the EIRP constraint can be adjusted upward, allowing for higher transmit power levels. Conversely, for comparatively smaller distances, the EIRP constraint can be adjusted downward, allowing for lower transmit power levels.

In wireless operating environments, wireless user devices are often within the coverage area of multiple base stations. The base station providing the best uplink for the user device may be different than the base station providing the best downlink for the user device. Systems and techniques for asymmetric uplink and downlink communications for a user device are provided. In embodiments, the user device initially synchronizes with a base station. Both the uplink and downlink are initially served by this base station. A determination is then made whether to handoff the downlink for the user device to another base station. When a determination is indicated, the downlink is handed off to the second base station. Thereafter, periodic measurements are made. The determinations whether to handoff the uplink and downlink for the user device are made independently.

A time domain channel response is determined from the estimated uplink channel. A sub-carrier distribution of uplink sounding sub-carriers is selected based on characteristics of the time domain channel response, wherein the distribution defines a spacing of pilot sub-carriers within the uplink sounding symbol. The subscriber transmits uplink sounding symbols having the selected sub-carrier distribution.
