    摘要： In a communications system, a User Equipment (UE) initiates a transmission of user data to a host computer by receiving a Random Access Response (RAR) message comprising an indication of a time-domain resource allocation for a Msg3 transmission on PUSCH, and determining a slot offset value, K2, for the Msg3 transmission based on the indication of the time-domain resource allocation and a PUSCH table. The UE adds an additional slot offset value for the Msg3 transmission to the slot offset value, K2, to provide an increased slot offset value for the Msg3, and transmits the Msg3 transmission in accordance with the increased slot offset value, wherein the additional slot offset value varies in relation to an additional processing time T add needed for RAR message decoding compared to PDCCH decoding. The UE then transmits, to the base station, the user data to be forwarded to the host computer.

    摘要： A method and a radio network node for estimating channel quality for a downlink transmission to a user equipment. The radio network node operates a first sector and a second sector. The radio network node is configured to send CSI-RS in the first and second sectors. The radio network node receives uplink reference signals, and determines a command based on the uplink reference signals, wherein the command indicates one of said at least one radio resource to be configured for CSI-RS. The radio network node sends the command to the user equipment, and receives a set of CSI reports, wherein the reports are generated by the user equipment according to the command. The radio network node receives further uplink reference signals from the user equipment, and estimates channel quality for the downlink transmission based on the set of CSI reports and the further uplink reference signals.
