    摘要： A method for channel estimation includes receiving data at a number of frequency intervals in a frequency band over a number of first time intervals. A first set of channel estimates is determined for each pilot symbol within the data over a second time interval comprising at least one first time interval, and time-direction interpolation is performed to determine a second set of channel estimates for a number of data portions in a frequency interval using the first set of channel estimates. The frequency interval comprises a data portion comprising a pilot symbol. Frequency-direction interpolation is performed to determine a third set of channel estimates for each first time interval. The time-direction interpolation and the frequency-direction interpolation can be performed in reverse order with the channel estimates generated by the frequency-direction interpolation being used as inputs for time-direction interpolation.

    摘要： A method for receiver processing in a 3GPP Long Term Evolution (LTE) receiver processing chain in a wireless mobile device is provided. LTE initial sub-frame transmitted from a base station is received on a LTE signalling channel. The sub-frame is received using a basic receiver. An integrity check is performed to determine if the sub-frame was demodulated and decoded correctly by the basic receiver. An advanced receiver is enabled prior to receiving an expected retransmission sub-frame based upon the integrity check failing and a hybrid-acknowledgement request (HARQ) negative acknowledgement (NAK) being sent by the wireless mobile device. The retransmission sub-frame is received using the advanced receiver. The basic receiver is enabled when the integrity check of the retransmission sub-frame passes and a acknowledgement (ACK) is by the wireless mobile device or a new data indicator (NDI) is set in a control channel indicating that the transmission is an initial transmission.

    摘要： Aspects of the present application include using adaptive measurement intervals to improve RSSI scan accuracy. A method may involve determining a first power value in respect of a first measurement time interval, determining whether or not the first power value meets at least one criterion, when the first power value does not meet the at least one criterion, determining at least one additional power value, selecting at least one power value from a set of power values that have been determined, the set including the first power value and the at least one additional power value, and determining the power value for use in cell selection or cell re-selection based on the selected at least one power value. The methods may be applied to any cell selection or re-selection scheme for which an adaptive measurement interval may be beneficial.

    摘要： A method, a system, a wireless device and a computer program product are provided. A process for decoding transmitted symbols in MIMO systems is provided. The received point coordinates and estimated candidate coordinates are represented by a reduced bit representation naturally dividing each dimension into uniformly sized bit segments. A bounded region surrounding the received point is defined in the total number of dimensions, the bounded region being a hypercube. For each candidate, an elimination process is carried out including: determining a position of the candidate to be inside or outside the bounded region, eliminating the candidate if it is outside, storing it if it is inside, adding a further bit thereby reducing a size of the bounding region; repeating the elimination process for the candidates stored as potential solutions until a single solution is obtained; determining the transmitted symbols from the single solution found.

    摘要： Described herein are methods and devices for use in telecommunication cell selection and re-selection for which there may be multiple different sizes of transmission bandwidth configurations in a telecommunications operating band. For each of a plurality of channel hypotheses, in which each channel hypothesis has a hypothetical occupied portion and a hypothetical guard band portion, a respective metric is calculated based on a power value for the hypothetical occupied portion and a power value for the hypothetical guard band portion. Based on the metrics determined for the plurality of channel hypotheses, at least one channel hypothesis is selected for further processing for cell selection or re-selection. The metric is calculated by determining a difference between the power value for the hypothetical occupied portion and the power value for the hypothetical guard band portion.
