摘要： The present disclosure relates to a method in a base station and to a base station for link adaption. The base station serves a UE and is configured to indicates a modulation and coding scheme and uplink radio resources for transmission by the UE of a succeeding flexible subframe. The base station receives an uplink transmission from the UE and demodulates one or more flexible subframes including perform error detection and determining an estimate of SINR. The base station determines if that flexible uplink subframe was affected by interference caused by a DL data payload transmission from a neighboring base station during that same flexible subframe. Based on that the decision, the base station determines and applies an adaptation value to the estimated SINR. It then selects a modulation and coding scheme or other transmission parameter(s), e.g., transmission bit rate, for a succeeding uplink transmission from the UE in the flexible uplink and provides it to the UE.

摘要： Method and arrangement in a relay node, for selecting communication mode. The relay node is configured to communicate with a base station via a donor antenna over a first link and to communicate with a user equipment via a coverage antenna over a second link. The method comprises obtaining an isolation value, based on the radio wave isolation between the relay donor antenna and the relay coverage antenna. The obtained isolation value is compared with an isolation threshold level value. The relay node is configured to communicate in full duplex mode if the obtained isolation value exceeds the isolation threshold level value, otherwise in half duplex mode. Information concerning the configured duplex mode of the relay node is transmitted to the base station. Also a method and arrangement in a base station is described.

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.
