Abstract: A method for retransmission of uplink transmissions, performed by a wireless device with configured uplink grants. The method comprises transmitting a first transmission to a network node with a redundancy version (RV). The wireless device then determines to retransmit the first transmission, and retransmits the first transmission with a retransmission RV based on the type of retransmission. For a non-adaptive retransmission, the retransmission RV value is the same as the RV of the first retransmission. For an adaptive retransmission, the retransmission RV is the RV value received in a retransmission grant.

Abstract: A cellular network supports radio communication based on a first configuration which organizes a time-frequency space in first resource elements and radio communication based on a second configuration which organizes the time-frequency space in second resource elements and assigns at least one of the second resource elements to a utilization which is in conflict with the radio communication based on the first configuration. A node (100-A) of the cellular network sends an indication (20) to a communication device (10-A, 10-B). The indication (20) comprises time domain and/or frequency domain information for defining a pattern comprising at least one of the first resource elements which is to be disregarded by the communication device (10-A, 10-B) when performing radio communication with the cellular network based on the first configuration and/or the second configuration.

Abstract: A system and method of Random-Access Response, RAR, messaging when a base station employs narrow beamforming. Multiple RAR messages are successively transmitted from the base station to a User Equipment, UE, before any response to a RAR message is received from the UE. Thus, despite any calibration mismatch between Uplink, UL, and Downlink, DL, beams in the beamformed system, a RAR message is not only received by the UE, but is received over the most-suitable DL beam for that UE. Each RAR message may contain a message-specific scheduling-delay indicator in the UL grant carried in the RAR message to provide an adjustable time delay for the UE's uplink transmission scheduled by the UL grant. Multiple RAR transmissions can schedule a single UL transmission at a specific time instance or different UL transmissions at different time intervals. The UE may report to the base station the best DL RAR transmission detected by the UE.
