    Abstract: It is presented a method for obtaining a set of selected antennas in a mobile communication network, wherein each one of the selected antennas is intended to be used in data transmissions to a first mobile communication terminal. The method is performed in a network node of the mobile communication network and comprises candidate the steps of: obtaining a set of candidate antennas, wherein each one of the candidate antennas is arranged to send out the same cell identifier and at least some of the candidate antennas have different coverage areas; evaluating performance of at least a subset of the candidate antennas in relation to the first mobile communication terminal; and determining a set of selected antennas based on the performance of the candidate performance antennas having been evaluated. A corresponding network node, computer program and computer program product are also presented.

    Abstract: A method of communicating with a wireless terminal may include providing first information (e.g. SIR or rate) responsive to receiving first and second multiple-input-multiple-output (MIMO) data streams from the wireless terminal through a first antenna array of a first sector during a first transmission time interval. Second information (e.g. SIR or rate) may be provided responsive to receiving the first and second MIMO data streams from the wireless terminal through a second antenna array of a second sector during the first transmission time interval, TTI, with the first and second sectors being different and the first and second antenna arrays being different. An offset value may be generated responsive to the first information and/or the second information, with the offset value defining a difference between the first and second MIMO data streams for a second transmission time interval (e.g. difference between data rates of first and second MIMO data streams), and the offset value may be transmitted to the wireless terminal.

    Abstract: Hybrid Automatic Repeat Request (HARQ) and retransmission procedures for multi-stream transmission are disclosed. An example method begins with the simultaneous sending (410) of first and second data packets, in respective first and second MIMO streams of a rank-2 transmission, and with the transmission (420) of corresponding control data for each of the first and second streams, using first and second associated control channels, respectively. The first and second associated control channels are distinguishable by their respective mappings to the transmitted signal. The method continues with the receiving (430) of HARQ data indicating that the first data packet was successfully decoded, while the second data packet was not. In response, the wireless transceiver retransmits (440) the second data packet in a single stream of a rank-1 MIMO transmission, and transmits (450) corresponding control data for the single stream using the second associated control channel.

    Abstract: At least one transport data block is transmitted from a first sector of anetwork over a downlink to a wireless terminal during a time resource element for a multi-flow downlink transmission to the wireless terminal, and at least one transport data block is transmitted from a second sector of the network over a downlink to the wireless terminal during the time resource element for the multi-flow downlink transmission. A feedback message is received for the time resource element from the wireless terminal, wherein the feedback message includes a HARQ-ACK codeword selected from a HARQ-ACK codebook providing HARQ- ACK feedback for the at least one transport data block transmitted from the first sector and for the at least one transport data block transmitted from the second sector. The HARQ-ACK codeword is interpreted for the at least one transport data block transmitted from the first sector based on the first sector being a primary sector for the multi-flow downlink transmission.
