摘要： Embodiments herein relate to a method in a network node (12,15) for managing transmit power of a user equipment (10) in a cellular network (1); wherein the network node (12,15) is comprised in the cellular network (1) and serves the user equipment (10). The network node (12,15) increases a power of a control channel of the user equipment (10). The network node (12,15) further limits a power increase of a data channel to a level by reducing a power of a serving grant of the user equipment (10) an amount, which amount corresponds to the increased power of the control channel. The network node (12,15) also reduces a reference value of the data channel for maintaining a transport block size of the data channel, which reference value determines mapping from the serving grant to the transport block size.

摘要： A method for synchronization in a network node is disclosed. The method comprises determining an N-symbol slice of a received signal, the N-symbol slice corresponding to a sync point hypothesis, dividing the N-symbol slice into one or more segments, each of the one or more segments having the same symbol length, and determining one or more phase rotation operators for each of the one or more segments, the determined one or more phase rotation operators compensating for a phase rotation introduced by an initial frequency error. The method further comprises performing coherent correlation within each of the one or more segments using the determined one or more phase rotation operators, and performing differentially coherent correlation on each of the one or more segments.

摘要： A frequency deviation estimator (20, 40) estimates an instantaneous frequency deviation in a received signal that includes pilot sub-blocks non-contiguously distributed in time across a radio block. Each pilot sub-block comprising one or more pilot symbols. The estimator (20, 40) is configured to select, from the pilot sub-blocks non-contiguously distributed in time across the radio block, a particular pilot sub-block for which to obtain an instantaneous frequency deviation estimate. The estimator (20, 40) applies a Fast Fourier Transform (FFT) or a Discrete Fourier Transform (DFT) to a set of contiguous received signal samples that spans multiple ones of the pilot sub-blocks, including the particular pilot sub-block as well as one or more assisting pilot sub-blocks neighboring that particular pilot sub-block. The estimator (20, 40) then obtains an instantaneous frequency deviation estimate for the particular pilot sub-block based on the resulting FFT or DFT outputs.

摘要： A method of calculating combining weight vectors associated with a received composite information signal comprising at least one data stream transmitted from at least a first antenna and a second antenna is disclosed. The method starts with computing a parametric estimate of an impairment covariance matrix including at least a first impairment term associated with common pilots deployed by the first antenna and the second antenna respectively. The first impairment term captures effects of interferences between the common pilots, in addition to effects of interferences caused by each common pilot singly. The impairment covariance matrix further includes a data covariance term capturing effects of the at least one data stream and an interference term caused at least partially by contribution of thermal noise of receiver branches. Then the method computes the combining weight vector using the computed impairment covariance matrix.

摘要： A network node of a wireless communication network serves a wireless device that is transmitting one or more uplink channels to each of a serving cell and at least one non-serving cell. Inner-loop power control, ILPC, commands are sent (420) to the wireless device in such a way that only ILPC commands transmitted by the serving cell affect the power of one or more control channels transmitted by the wireless device to the serving cell. In addition, a power offset for a data channel transmitted by the wireless device to the at least one non-serving cell is adjusted (430), so as to compensate for an uplink-downlink power imbalance among the serving cell and the at least one non-serving cell.

摘要： A method that is implemented by a base station to decode a high speed dedicated physical control channel (HS-DPCCH) using a preamble and postamble of a hybrid automatic repeat request (HARQ) message while maintaining a fixed false alarm probability of interpreting a discontinuous transmission (DTX) as a HARQ acknowledgement (ACK) or HARQ negative acknowledgement (NACK). The method includes a set of steps, including receiving a signal from a user equipment (UE). The signal is despread using a G-RAKE demodulator. The despread signal is combined to produce a combined symbol estimate vector x including a preamble and postamble of the HARQ message. The combined symbol estimate vector x is checked to determine whether the signal includes a DTX, HARQ ACK or HARQ NACK, and then the DTX, HARQ ACK or HARQ NACK is output.

摘要： A signal is received containing a block of multiple symbols, each symbol containing information bits spread by a spreading sequence of chips. Each spreading sequence is determined by a channelization sequence and a first or second complex-valued scrambling sequence of chips. Each block is processed using a set of spreading sequences using correlations between pairs of spreading sequences in the set. Spreading sequence correlation values between each pair are manipulated and stored in lookup tables. A lookup table address is determined using a first set of reduced basic scrambling bits to retrieve correlation values. The first set of reduced basic scrambling bits is based on manipulation of one set of the basic scrambling bits that reduces a number of bits included in the determined address to less than a number of binary values in the one set of basic scrambling bits. The one set of basic scrambling bits is used to construct one of the first and second complex-valued scrambling sequences. The retrieved correlation values may be used in mitigating spreading sequence correlation interference between spreading sequences in the set.

摘要： A method in a network node for enhancing a channel estimate based on a Dedicated Physical Control Channel, DPCCH, between a user node and the network node is provided. The DPCCH has a first power. The network node receives (501) the DPCCH. The first power of the DPCCH is boosted with additional power, resulting in a second power. The network node then obtains (502) a channel estimate based on the DPCCH comprising the second power. As soon as said channel estimate is obtained, the network node removes (503) the additional power from the DPCCH based channel estimate.
