Abstract: The present disclosure introduces methods and apparatus for configuring or preconfiguring random access procedures when there are multiple configurable numerologies for one carrier. In some embodiments, the random access numerology of the wireless device is configured using the system information block. In other embodiments, the random access numerology used by the wireless device is determined implicitly based on the detection of one or more synchronization signals.

Abstract: A wireless device (12) determines that an uplink control channel resource (20B) for a multi-slot uplink control channel transmission (16B) overlaps in time with an uplink control channel resource (20A) for a single-slot uplink control channel transmission (16A) in a slot (18X). The wireless device (12) decides, for the slot (18X), either to drop whichever of the multi-slot uplink control channel transmission (16B) and the single-slot uplink control channel transmission (16A) carries uplink control information of a lower priority or to drop a certain one of the multi-slot uplink control channel transmission (16B) and the single-slot uplink control channel transmission (16A), depending on whether the multi-slot uplink control channel transmission (16B) and the single-slot uplink control channel transmission (16A) carry uplink control information of different priorities or the same priority, respectively. The wireless device (12) drops the single-slot uplink control channel transmission (16A) or the multi-slot uplink control channel transmission (16B) in the slot (18X), according to that decision.

Abstract: Operating a wireless device in a wireless communication network, the wireless device being triggered for transmitting first signaling on a first resource structure associated to a first transmission quality and being triggered for transmitting second signaling on a second resource structure associated to a second transmission quality, the first resource structure and the second resource structure overlapping at least partly in time and/or being in the same transmission timing structure; the first signaling being communication signaling and representing first information, and the second signaling being control signaling representing second information, which is control information. Signaling is transmitted on the first resource structure, the signaling including second information mapped to the first resource structure, depending on the size of the first resource structure and the size of the resources within the first resource structure required by the mapping of the second information. The disclosure also pertains to related devices and methods.

Abstract: Methods and apparatuses disclosed herein enable the use of Demodulation Reference Signal (DMRS) sequences that are numbered relative to an overall system bandwidth, while simultaneously enabling wireless communication devices to determine the DRMS sequence elements mapped to their scheduled bandwidths within the system bandwidth. Advantageously, the wireless communication devices need not know the system bandwidth, or even be aware of where their scheduled bandwidths reside within the system bandwidth.

Abstract: A network node causes transmission of DCI that includes information for scheduling two or more TBs over two or more communication slots. The two or more TBs are associated with two or more HARQ process IDs. The information includes one or more of: a PUCCH resource indicator configured to indicate at least one resource for use for transmitting HARQ feedback related to the two or more TBs; a DAI configured to indicate a position of HARQ feedback related to the two or more TBs, in a HARQ codebook; a HARQ process ID indicator indicating two or more HARQ process IDs; and one or more NDIs configured to indicate whether at least one of the two or more TBs is a retransmission.
