摘要： Methods, systems, and devices are described for low latency communications within a wireless communications system. An eNB and/or a UE may be configured to operate within the wireless communications system and may send triggers to initiate communications using a dedicated resource in a wireless communications network that supports transmissions having a first subframe type and a second subframe type, the first subframe type comprising symbols of a first duration and the second subframe type comprising symbols of a second duration that is shorter than the first duration. Communications may be initiated by transmitting a trigger from the UE or eNB using the dedicated resource, and initiating communications following the trigger. The duration of time between the trigger and initiating communications can be significantly shorter than the time to initiate communications using legacy LTE communications.

摘要： An apparatus, configured to communicate with other apparatuses in a wireless network and operating in a frequency-division duplexing mode, can be caused to refrain from transmitting during a number of subframes of a frame of a downlink frequency band prior to a detection of a radar transmission, can be caused to send a first signal, related to monitoring for the radar transmission, to a second apparatus, and can be caused to change the number of the subframes of the frame of the downlink frequency band in response to an event that can be an increase or a decrease in a load of the apparatus or the detection of the radar transmission. Optionally, placement of the subframes within the frame of the downlink frequency band can correspond to placement of subframes that are designated for an uplink communication within a frame configured in accordance with the Long-Term Evolution Time-Division Duplex standard.

摘要： A computing device operating according to a frequency division multiplexed protocol in which communication occurs over a signal formed from a plurality of sub-channels selected from anywhere in a frequency spectrum. A computing device may select sub-channels cognitively by using information about sub-channels previously deemed suitable or unsuitable by that computing device or other computing devices. A described technique for determining sub-channel suitability includes analyzing radio frequency energy in the sub-channel to detect signals generated by another computing device or high noise levels. Information may also be used to cognitively select sub-channels to be analyzed, such as by first selecting for analysis previously-used sub-channels.

摘要： Improved diagnostics of transmission line (100) noise are enabled by adapting DSL equipment (110, 120) to make measurements of quiet line noise also in the transmit bands, so that noise can be measured at both ends for the same frequency or frequency bands. An estimate of the point where noise enters the line, as well as an estimate of the noise power at that point can be made from the relationship between the so measured noise levels at both ends of the line.
