According to certain embodiments, a method for use in a wireless device for transmitting uplink control information (UCI) on grant-free resources comprises reserving a subset of time/frequency resources of a grant-free uplink channel for transmitting UCI, and upon determining the wireless device has UCI to transmit on the grant-free uplink channel, transmitting the UCI to a network node in the reserved subset of time/frequency resources.

UCI on grant-free PUSCH

There is disclosed a method of operating a terminal () in a wireless communication network, the method comprising receiving and/or transmitting according to a transmission time interval, TTI, configuration, the TTI configuration indicating at least one short transmitting time interval having between one or two and seven symbols of duration in a subframe. There are also disclosed related methods and devices.

Short TTI patterns

According to certain embodiments, a method by a wireless device is provided for transmitting uplink control information (UCI) on a serving cell on the unlicensed spectrum. The method includes formatting the UCI as a shortened control signalling transmission and transmitting the UCI formatted as the shortened control signalling transmission to a network node. The shortened control signalling transmission is transmitted during a transmission opportunity on the serving cell on the unlicensed spectrum without performing channel sensing.

Systems and methods for uplink control information signaling design

According to an aspect, a transmitting device determines, for each of a plurality of transmissions, whether user data to be transmitted within a time transmission interval, TTT, will be closest in time to a DMRS transmitted before the user data or after the user data. If before the user data, all HARQ ACK/NACK data for the transmission is mapped to the earliest in time SC-FDMA symbol carrying user data in the transmission, and to pre-DFT symbols closest in time to the DMRS transmitted before the user data. If after the user data, all HARQ ACK/NACK data for the transmission is mapped to the last in time SC-FDMA symbol carrying user data in the transmission, and to pre-DFT symbols closest in time to the DMRS transmitted after the user data. SC-FDMA signals are formed from user data and control information for the transmission, based on the mapping.
