摘要： A base station includes transmitter and associated processing circuits. The transmitter circuits are configured to transmit control information and data traffic to mobile terminals in repeating transmission intervals, each interval having defined control and data portions. The processing circuits are configured to dynamically determine that the control portion has insufficient resources for transmitting control information to one or more of the mobile terminals, and, in response, at least temporarily transmit control information in the data portion, rather than in the control portion, for a selected one or more of the mobile terminals. Correspondingly, a mobile terminal is configured to selectively search for and decode control information in the data portion of one or more transmission intervals, rather than in the control portion.

摘要： A method of decoding a signal that has been encoded by a tail-biting code based on at least one encoding parameter is disclosed. The at least one encoding parameter may be a trellis size or a quantity of aggregated encoding elements or a code rate. The method is suitable for use in a communication device and comprises receiving (510) the signal, performing (520) a first decoding attempt of the signal based on a first set of starting state metrics and a first encoding parameter hypothesis, the first decoding attempt resulting in a first set of ending state metrics. The method further comprises performing (520), if the first decoding attempt fails, a second decoding attempt of the signal based on a second set of starting state metrics based on the first set of ending state metrics and a second encoding parameter hypothesis different from the first encoding parameter hypothesis. Corresponding arrangement, communication device, and computer program product are also disclosed.

摘要： Methods and apparatus are disclosed for estimating inter-cell interference levels for resource elements of a received Orthogonal Frequency-Division Multiplexing (OFDM) signal. In an exemplary method in a wireless receiver, a reference symbol interference levels is measured for each of a plurality of reference symbols in a received OFDM signal, and interference scaling factors are mapped to each of a plurality of resource elements of the received OFDM signal. Each interference scaling factor reflects the probability that the corresponding resource element or group of resource elements is subject to interference from an interfering OFDM signal. Interference levels for each of the resource elements are then estimated as a function of the measured reference symbol interference levels and the interference scaling factors.

摘要： Systems and methods according to these exemplary embodiments provide for optimizing voltage use in digital circuits. This can be obtained by creating situations for digital circuits such that the effective critical path (ECP) can be used such as, for example, the case where a digital circuit includes a plurality of voltage domains powered by individual and possibly different voltage sources. This can then reduce voltage use in digital circuits.

摘要： The systematic and parity bits of a symbol are tightly coupled to each other based on the way in which the symbol is encoded. The relationship between the systematic and parity bits can be exploited to improve the accuracy of soft bit estimation for both the systematic bits and parity bits. In one embodiment, a received symbol is processed by demodulating the received symbol to determine an initial soft estimate of each systematic bit and corresponding one or more parity bits in the sequence. The systematic bit sequence is iteratively decoded to revise the soft estimate of the systematic bit. The initial soft estimate of the one or more parity bits associated with each systematic bit is revised based on the revised soft estimate of each systematic bit. The received symbol can be decoded or regenerated based on the revised soft estimate of each systematic bit and corresponding one or more parity bits.
