摘要： Systems and methods for providing an efficient mechanism for transmitting encoded downlink assignment index (DAI) and for signaling the ACK/NAK information corresponding to downlink grant allocations in an over the air radio telecommunications network with time division duplex (TDD) capability, where aggregation of component carriers (CCs) is used. Downlink control messages containing encoded DAI information are transmitted with downlink allocation grants. A receiver observes the encoded DAI and the downlink allocation grants and forms corresponding ACK/NAK signals. Method embodiments for forming the ACK/NAK signals for CC groups and frames or subframes are provided. The ACK/NAK signals are then encoded using method embodiments and transmitted over parallel channels for each CC group to the transmitter. By using method embodiments for selecting resources for use in the transmission, the last observed DL grant can be identified by the transmitter and the transmitter can detect an error at the receiver.

摘要： Systems and methods are provided for enabling different “bundling” methods for downlink transmissions and provide different interpretations of the acknowledgement/negative-acknowledgement bit. A user equipment is configured so that it commonly acknowledges all downlink transmission time intervals within a bundle so that if one packet is determined to be erroneous, all packets in that bundle will be retransmitted. Additionally, the systems and methods are implemented by allowing an interpretation to be applied to the uplink acknowledgement/negative-acknowledgement field such that the user equipment is able to divide bundled downlink packets into smaller windows in Long Term Evolution (LTE) Release 8 time division duplex (TDD) mode. In LTE Advanced (LTE-A) TDD mode, various embodiments provide bundling within the time domain, within the frequency domain, and within a hybrid time-frequency domain. Furthermore, enhanced channel selection methods are also provided in support of the above-mentioned bundling methods in accordance with various embodiments.

摘要： A gas sensor includes an in-fiber resonant wavelength device provided in a fiber core at a first location. The fiber propagates a sensing light and a power light. A layer of a material is attached to the fiber at the first location. The material is able to absorb the gas at a temperature dependent gas absorption rate. The power light is used to heat the material and increases the gas absorption rate, thereby increasing sensor performance, especially at low temperatures. Further, a method is described of flash heating the gas sensor to absorb more of the gas, allowing the sensor to cool, thereby locking in the gas content of the sensor material, and taking the difference between the starting and ending resonant wavelengths as an indication of the concentration of the gas in the ambient atmosphere.
