摘要： Systems and/or methods of receiving communications at a receiving node that communicates with a transmitting node over a first communication channel and a second communication channel are disclosed. The method includes receiving, at the receiving node, a request-to-send message from the transmitting node over the first communication channel, the request-to-send message indicating that the transmitting node has data to be transmitted to the receiving node over the second communication channel, determining at the receiving node whether the second communication channel is available for reception of the data, in response to determining that the second communication channel is available for reception of the data, reserving the second communication channel for use by the transmitting node, and receiving the data from the transmitting node over the second communication channel.

摘要： 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. In response to determining that the channel is free, transmission is initiated on the channel.

摘要： 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.

摘要： Systems and methods of performing a listen-before-talk (LBT) radio protocol in a communication system are provided. In one exemplary embodiment, a method (600) by a radio component (403, 503) of a wireless device (400, 500) may include receiving (601), by the radio component, from a baseband component (401, 501) of the wireless device, transmit data during a transmit-time interval associated with a synchronous wireless communication system. Further, the method may include, detecting (603), by the radio component, that a medium associated with an asynchronous communication system is available. Also, in response to detecting, the method may include, transmitting (605), by the radio component, the transmit data on the medium during the transmit-time interval.
