Patent number: 10555342Abstract: According to certain embodiments, a method by a radio node (110, 115) operating in multiple modes for power detection includes operating in a first mode. While operating in the first mode power levels of transmissions on a channel are compared to a first threshold to determine whether the channel is free. While operating the radio node (110, 115) in the first mode, power levels within a specified range are detected during a first time period. In response to detecting the power levels within the specified range during the first time period, the radio node (110, 115) is switched to a second mode that is a duty-cycle mode. While operating the radio node (110, 115) in the second mode, the power levels of the transmissions on the channel are compared to a second threshold during a first portion of a duty cycle and to a third threshold during a second portion of the duty cycle to determine whether the channel is free. The third threshold is different from the second threshold.Type: GrantFiled: October 5, 2016Date of Patent: February 4, 2020Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Jung-Fu Cheng, Håkan Andersson, Ashim Biswas, Daniel Figueiredo, John Skördeman

Patent number: 10542566Abstract: A technique for performing a clear channel assessment (CCA) in an unlicensed radio frequency (RF) spectrum is described. The CCA is performed for transmitting data (420) according to a first radio access technology (RAT) in coexistence with a second RAT. As to a method aspect of the technique, signals (411) are received in the unlicensed RF spectrum. The received signals (411) are processed according to an operating state. The processing in a first operating state (402) causes a first delay that is greater than a second delay caused by the processing in a second operating state (404). The operating state depends on the presence of data (420) to be transmitted according to the first RAT in the unlicensed RF spectrum. The CCA is performed based on the processed signals.Type: GrantFiled: January 27, 2017Date of Patent: January 21, 2020Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Håkan Andersson, Ashim Biswas, Daniel Figueiredo
