摘要： Systems and methods for controlling in situ resistive heating elements may be utilized to enhance hydrocarbon production within a subterranean formation. An in situ resistive heating element may be controlled by heating a controlled region associated with the in situ resistive heating element, injecting a control gas into the controlled region, and adjusting the electrical conductivity of the controlled region with the control gas. The controlled region may be located such that the heating and injecting may change the shape of the in situ resistive heating element and/or guide the in situ resistive heating element towards subterranean regions of potentially higher productivity and/or of higher organic matter.

摘要： An exemplary method of communicating includes multiplexing control signaling in a physical uplink control channel (PUCCH) onto a physical uplink shared channel (PUSCH) by puncturing PUSCH data with PUCCH control information using a uniform distribution of the PUCCH information within at least one resource block of the PUSCH data. One example includes using a first constant amplitude zero autocorrelation sequence (CAZAC) index on PUCCH for communicating CQI and ACK information together and using a second, different CAZAC sequence index for communicating CQI information alone or with NAK information or DTX. The used index provides an indication of whether ACK information is communicated. The used index also provides implicit DTX detection without additional processing.

摘要： A low complexity RACH preamble detector is described herein. The RACH is filtered out of the received signal in the time domain through a low pass polyphase filter (22) and the decimated (24). By consequence the dimension of the FFT can be reduced. The RACH is extracted from the output of the FFT and it is correlated with a CAZAC frequency domain reference sequence (16). Thereafter, the signal obtained is transformed in the time domain (18) and a peak is retrieved (20).

摘要： The present invention provides a method of processing a baseband signal including user signals transmitted by a plurality of users. The method includes applying frequency offset compensations to the baseband signal, thereby to form respective frequency-shifted baseband signals. Each frequency compensation shifts the baseband signal by a multiple of a selected frequency offset and each resulting frequency-shifted baseband signal includes frequency-shifted user signals. The method also includes assigning at least some of the frequency-shifted user signals to groups. Each group corresponds to one of the frequency compensations and the assignment is carried out so that each group includes frequency- shifted user signals that have an estimated frequency offset that lies within a range determined by the corresponding frequency compensation. The method further includes estimating a frequency offset of each of the user signals based on the frequency-shifted user signal and the frequency compensation of the group including the frequency-shifted user signal.

摘要： A communication system includes a decentralized, flat architecture where a plurality of base nodes each include controller capabilities so that a centralized base node such as a radio network controller is not required. At least one of the base nodes acts as an anchor node. The anchor node associates a time stamp with at least one packet and provides that to the plurality of base nodes. In one example, a multicast approach is used by a router device for distributing the packet and the associated time stamp to the plurality of base nodes. Each base node controls a timing of a transmission of the at least one packet over a wireless interface responsive to the associated time stamp.
