摘要： The present invention relates to a method and an arrangement (20) of increasing impairment co-variance matrix R u estimation accuracy in downlink in a user equipment (18) in a communication network system. De-spread is performed on HS-DSCH symbols to form a matrix X of de-spread symbols (100). The matrix X and channel estimates h c from CPiCH and modulation scheme information are used to form a matrix S of recovered symbols in hard value (101 ). The matrix X and the channel estimates h c1 the modulation scheme information and the matrix S output from the previous step are used to increase the estimation accuracy of the matrix S (102). The previous step (102) is repeated until the output symbols are the same as the input symbols or the number of iterations reaches a pre-defined maximum value (103). The matrix X and the matrix S with increased estimation accuracy are used to form an impairment co-variance matrix R u estimate (104). The impairment co-variance matrix R u estimate and the channel estimates h c from CPiCH are used to determine G-RAKE combining weight w and to estimate CPiCH SINR (105).

摘要： The present invention discloses a node for transmission mode switching for downlink transmission in a downlink channel (100), comprising: a configuring unit (110) adapted to configure an initial transmission mode for the downlink transmission as a default transmission mode; a deriving unit (120) adapted to derive channel quality metric (CQM) of the downlink channel; a first determining unit (130) adapted to determine a first predefined threshold on the basis of link level simulation of a first transmission mode and a second transmission mode; and a first switching unit (140) adapted to switch the transmission mode from the initial transmission mode to the first transmission mode or the second transmission mode on the basis of the CQM and the first predefined threshold. The present invention provides a simple, direct and efficient approach for transmission mode switching for downlink transmission in a downlink channel on the basis of available feedback from UE (or other kinds of terminals if appropriate) and/or link adaptation decisions from eNB (or other kinds of base stations if appropriate), provides high peak rate while maintaining cell coverage, and provides a proprietary solution without any impact on protocol/standard or UE implementation.

摘要： The present invention relates to an arrangement and method to design orthogonal UE-specific reference signals so that multiple UE-specific reference signals are feasible to support non-codebook-based multi-stream beamforming/precoding. This is achieved by re-using an existing UE-specific reference signal to obtain additional UE-specific reference signals being orthogonal to the existing UE reference signal.

摘要： The invention relates to a method and an arrangement for obtaining efficient radio resource utilization in a communication network comprising a communication network entity transmitting data on a downlink channel over a radio interface to one or more user equipments, each of which is transmitting data on an uplink channel to said communication network entity over said radio interface. The communication network entity receives transmit power control (TPC) commands on said uplink channel and, further, monitors a channel quality indicator (CQI) on said uplink channel from said user equipment in order to obtain channel quality indicator measurements. If there is a channel quality indicator available, the communication network entity calculates a required downlink power. Otherwise, the communication network entity decodes said received transmit power control commands. Thereafter said transmission power is adjusted either based on the calculated downlink power or based on the decoded transmit power control commands in order to obtain efficient radio resource utilization.

摘要： The present disclosure provides a method implemented in a wireless communication device for estimating a frequency offset between a carrier frequency of a received signal and a frequency of a local oscillator as well as the wireless communication device. The method comprises determining a plurality of phase change candidates for a phase change between a data symbol and a first reference symbol in the signal. The method further comprises generating a collection of constellation symbols from the data symbol and rotating the collection of constellation symbols by the plurality of phase change candidates. Then, one of the phase change candidates corresponding to one of the rotated collections of constellation symbols is selected in such a manner that said one of the rotated collections of constellation symbols matches a set of constellation points best. Next, the frequency offset is determined based on the selected phase change candidate.
