Publication number: 20210288681Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for a DPD training procedure. A base station may transmit, for a plurality of iterations, a signal to at least one UE through a plurality of transmit chains and with application of DPD. The signal transmitted for each iteration may be transmitted with a BW that extends over a plurality of subcarriers and includes pilots extending over a BW subset that increases in subcarrier size for each iteration. The base station may receive, for each iteration, feedback from the at least one UE based on the transmitted signal and apply DPD to each of the plurality of transmit chains based on the feedback. Accordingly, the base station may transmit to one or more UEs through the plurality of transmit chains and with application of the DPD pilot signals that extend over the entire BW.Type: ApplicationFiled: March 12, 2020Publication date: September 16, 2021Inventors: Igor GUTMAN, Michael LEVITSKY, Assaf TOUBOUL, Ronen SHAKED

Patent number: 10651967Abstract: Aspects of the present disclosure provide a method performed at a user equipment (UE) that includes determining a first suggested modulation coding scheme (MCS) and a second suggested MCS for one or more first time periods and one or more second time periods, respectively, based on first/second time differences between the one or more first time periods/second time periods and one or more time periods allocated for a demodulation reference signal (DMRS). The method further includes receiving, from the BS, an indication of a first MCS and a second MCS determined by the BS based on the first suggested MCS and the second suggested MCS.

Patent number: 10404334Abstract: A 5G base station transmitter at least partially precodes data for beam forming, and generates digital precoded baseband signals. Cross product circuitry coupled to the digital precoder, generates digital cross products of the digital precoded baseband signals. Both the baseband signals and the cross products are put through digital-to-analog converters (DACs), then provided to an analog non-linear precoder. The analog non-linear precoder combines the analog baseband signals, the cross products, with pre-distortion and precoder coefficients to generate a signal that is pre-compensated for power amplifier non-linearity. The pre-compensated signal is amplified by the power amplifier and transmitted via a phased antenna array. The number of extra DACs required for inserting pre-distortion when a hybrid digital/analog precoder is used can be limited to approximately N RF ? ( N RF - 1 ) 2 , where NRF is the number of outputs of the digital precoder.Type: GrantFiled: September 28, 2018Date of Patent: September 3, 2019Assignee: Maxlinear Asia Singapore PTE LTDInventor: Ronen Shaked

Publication number: 20190215139Abstract: Systems and methods are provided for digital interference cancellation during continuous wave (CW) tests for high quadrature amplitude modulation (QAM) for point-to-point frequency-division duplexing (FDD) systems. During reception of signals, test signals that are configured for assessing performance in accordance with a particular criterion, in a device or a system handling the reception, may be injected. During processing of the received signals, and in response to a determination that the test signals and one or more other signals different than the received RF signals, cause interference to the received RF signals, and where the interference is unrelated to the assessing based on the criteria, one or more cancellation adjustments may be applied, during processing of the RF signals, for mitigating effects of the interference.Type: ApplicationFiled: January 8, 2018Publication date: July 11, 2019Inventors: Kobi Sturkovich, Ronen Shaked, Eitan Tsur

Patent number: 10243601Abstract: A system and method for frequency reuse for wireless point-to-point backhaul. Frequency reuse is enabled through the cancellation of interfering signals generated by interference sources. In one embodiment, a conventional dish antenna is complemented with one or more additional auxiliary antennas (e.g., isotropic). The one or more additional auxiliary antennas enable cancellation of interfering signals whose direction of arrival (DOA) is off the dish antenna's bore-sight.Type: GrantFiled: December 4, 2017Date of Patent: March 26, 2019Assignee: MAXLINEAR ASIA SINGAPORE PTE LTDInventors: Ronen Shaked, Ilan Reingold, Eitan Tsur, Eran Ridel
