Abstract: One aspect provides a method of controlling transmit power in a wireless device, wherein a desired transmit power is determined as a result of detection of a receive signal parameter. The method comprises detecting a desired maximum transmit power and generating a sequence of attenuation factors. The sequence is generated by monotonically increasing a variable at a controlled rate between a starting value and the maximum transmit power. The method further comprises using each attenuation factor in turn to: (a) reduce the measured value of the received signal power; and (b) reduce a determined desired value of the transmit power, where the transmit power is continually reduced as the variable is increased.

Abstract: Method, receiver and computer program product for decoding a coded data block received at the receiver are disclosed. A first plurality of coded data bits representing the coded data block are received. First soft information values are determined corresponding to respective ones of the received first plurality of coded data bits, wherein each of the soft information values indicates a likelihood of a corresponding coded data bit having a particular value. An attempt is made to decode the coded data block using the first soft information values. The first soft information values are compressed. The compressed first soft information values are stored in a data store. A second plurality of coded data bits representing the coded data block is received and second soft information values corresponding to respective ones of the received second plurality of coded data bits are determined. The compressed first soft information values are retrieved from the data store and decompressed. The decompressed first soft information values are combined with the second soft information values, and an attempt is made to decode the coded data block using the combined soft information values.
