摘要： The present disclosure proposes methods for performing and controlling retransmission in a MIMO system and relevant network elements therefor. A method for performing retransmission includes transmitting one or more data blocks to the base station by using a first set of beams. The number of beams in the first set of beams corresponds to a first channel rank. Each beam of the first set of beams is generated by using at least one of pilot channel, data channel and control channel. The method further includes receiving a signal from the base station indicating erroneously received data blocks, and retransmitting the erroneously received data blocks in response to the signal.

摘要： A method of coordinated scheduling of a downlink transmission flow from a first radio network node to a user equipment UE in a second radio network node. The method includes scheduling the downlink transmission flow so that the in-sequence delivery of the received data blocks can be kept in an acceptable level in the UE by adjusting a scheduling priority of the downlink transmission flow in the second radio network node. The method may further include estimating one or more buffer-related parameters based on buffered data for the downlink transmission flow from the first radio network node, and determining, based on the estimated one or more buffer-related parameter and/or one or more parameters associated with the operation status of the second radio network node, if the in-sequence delivery of the received data blocks to higher layers can be in an acceptable level in the UE.
