    • 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.

    • 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).

    • An intelligent assisted transmission method is provided. In the method, a Multicast and Broadcast Service (MCBCS) Server transmits Multicast Broadcast Service (MBS) data to a base station in an MBS area. The base station transmits the MBS data to a user equipment. If the user equipment cannot correctly receive the MBS data, it returns a Not Acknowledgement (NACK) message to the base station. The base station transmits an intelligent assisted transmission prompt to the MCBCS Server. The MCBCS Server transmits an intelligent assisted transmission request to adjacent base stations of the base station. When the intelligent assisted transmission request is received, the adjacent base stations return an intelligent assisted transmission response. The MCBCS Server transmits the MBS data to the adjacent base stations, and the adjacent base stations transmit the MBS data to the user equipment.
