摘要： Network connection is provided by a method is performed in a control node. An indication pertaining to at least partly transfer a data transmission service of a wireless device from using a first network access method to using a second network access method associated with a network node is received. The network node is associated with a compatibility version. The indication comprises a compatibility version of the wireless device for the second network access method. The compatibility version of the wireless device is compared to the compatibility version of the network node. It is determined if there is a version mismatch between the compatibility version of the wireless device and the compatibility version of the network node. If so, the an expected performance impact of the wireless device using the second network access method is determined. Based on the determined performance impact, it is indicated whether or not the wireless device is allowed to establish a connection to the network node.

摘要： The embodiments of the present disclosure disclose a soft bit un-uniform quantization method, apparatus, computer program and storage medium. The soft bit un-uniform quantization method comprises: determining a threshold value; obtaining a quantization step according to the threshold value; obtaining a first data after a QAM demodulating and before a Turbo decoding in a wireless communication system; and performing a soft bit un-uniform quantization on the first data to obtain a quantization result according to the threshold value and the step. According to the present disclosure, the data after the QAM demodulating and before the Turbo decoding may obtain a distinguished Euclidean distance value and thus the performance can be improved greatly.

摘要： Systems and methods are provided for authenticating Internet Protocol (IP) Multimedia Subsystem (IMS) applications in a User Equipment (UE). A method includes: receiving a first Session Initiation Protocol (SIP) REGISTER message from an IMS application operating on the UE; transmitting a response message to the IMS application based on the received first SIP REGISTER message; receiving a second SIP REGISTER message from the IMS application operating on the UE; determining authentication for the IMS application based on the received second SIP REGISTER message from the IMS application operating on the UE; and based on the step of determining authentication for the IMS application, if the IMS application is authorized, then transmitting information associated with the first and second SIP REGISTER messages toward a SIP node or if the IMS application is unauthorized, then discarding data associated with the first and second SIP REGISTER messages.

摘要： In one aspect, the present invention exploits the termination conductances of a time-discrete harmonic mixer as another degree of freedom in configuring the mixer to meet given harmonic rejection performance requirements while using reduced number of unit cells. The values of these termination conductances are purposefully configured to introduce a desired non-linearity in quantization of the mixer transconductance by the unit cells. The non-uniform quantization produces a non-linear fitting of the transconductance levels to the transconductance points defining the target sinusoidal waveform. As a consequence of its termination conductance configuration, the contemplated mixer achieves levels of harmonic rejection with that would not be met if the reduced number of unit cells operated with uniform quantization. As a further advantage, the manipulated conductance values generally are lower than those used in conventional designs, e.g., on par with the maximum conductance of the mixer, as provided by mixer's set of unit cells.

摘要： View synthesis is performed based on obtained texture data and a depth map. The resolution of the depth map is lower than that of the texture data by a ratio dw in the x direction and by a ratio dh in the y direction. Texture pixel positions x, y are transformed into non-integer depth map pixel positions by performing divisions x/dw and y/dh and these non-integer depth map pixel positions are rounded to integer depth map pixel positions, and a view is synthesized based at least on the obtained texture data and depth map values at the integer depth map pixel positions and/or adjacent positions.

摘要： A network node that serves a cell in a cellular communication system is operated. An air interface of the cellular communication system is divided up into sequentially occurring frames, each of the frames comprising a plurality of sequentially occurring sub-frames, each of the sub-frames comprising a plurality of sequentially occurring symbols. Operation includes receiving and detecting a request signal transmitted by a device within the cell. Based at least in part on a characteristic of the request signal that is indicative of one or more device capabilities of the device, an associated time/frequency position for transmitting a response signal is ascertained. The response signal is transmitted at the ascertained time/frequency position.

摘要： Disclosed is an inductor (200, 1000, 1300) comprising an inductor coil (202) and terminals (204a, 204b; 1310a, 1310b). The inductor (200, 1000, 1300) is substantially symmetric about a symmetry axis. The inductor coil (202) has a first loop (206a; 1004; 1002) and a second loop (206b; 1006; 1008) arranged such that current in the first loop (206a; 1004; 1002) travels in a direction that is opposite to current in the second loop (206b; 1006; 1008) such that electromagnetic field components emanating at a certain distance from the first loop (206a; 1004; 1002) and the second loop (206b; 1006; 1008) also have opposite directions and tend to counteract each other.

摘要： A high-sensitivity receiver may be made by using multiple demodulators to demodulate a given signal. For example, the receiver may use a first demodulator to demodulate an input signal into a first sequence of soft bits and a second demodulator to demodulate the same input signal into a second sequence of soft bits. The two sequences of soft bits may then be compared and combined to create a sequence of hard bits. For example, in some embodiments, a soft bit combiner may combine the two sequences of soft bits into a third sequence of soft bits, which may then be input into a decoder to produce the final decoded hard bits. The secondary demodulator may be less complex, less expensive, demand less power, and/or require fewer computational resources when operating, than the first demodulator.
